FIG. 3 is a schematic diagram showing the principle of the third embodiment of the negative pressure tube residual cleaning mechanism of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the invention can be implemented in various different ways as defined and covered by the claims. Referring to FIG. 1 , the negative pressure tube accumulation and cleaning mechanism fixing device of the utility model is installed on a storage device, and the first embodiment of the vacuum tube accumulation and cleaning mechanism of the utility model is used for the storage tank. The feces in 1 are removed. The negative pressure take-up tube surplus cleaning mechanism includes a toilet passage 8, a pipe tee 6 and a fluid connected to the toilet passage 8 for cleaning out the accumulated feces in the toilet pipe of the pick-up device Lead channel 3. The sump 1 is provided with a receiving passage 12 through which a defecation from a toilet or a toilet can be input into the sump 1, and the accommodating passage 12 is open to the outside. The outlet passage 8 is an outer portion of the toilet passage 1 of the toilet bowl 1, which communicates with the storage tank 1. After the toilet valve 7 is connected in series on the outlet passage 8, it is connected in series with the pipe tee 6. The outlet end interface of the pipe tee 6 exits the joint 5. The branch interface of the pipe tee 6 is connected to the inlet valve 2 of the fluid connection passage 3, and the inlet end of the fluid connection passage 3 is provided with the fluid bucket 4; that is: the branch interface and the fluid of the pipe tee 6 The connecting passage 3 is connected, and the fluid guiding passage 3 is provided with an inlet valve 2, and the inlet valve 2 is located between the fluid inlet 4 and the branch port of the pipe tee 6. The fluid bucket 4 is taken as an open container, and water is injected into the circulation bucket 4 to constitute a water plug action negative pressure take-up tube accumulation cleaning mechanism. When the negative pressure draining tube surplus cleaning mechanism of the present invention is used for taking the toilet, the toilet valve 7 is opened, and the airing valve 2 is in the off state, and the pick-up device (not shown) is taken. The pick-up interface device is connected with the toilet connector 5, and the pick-and-place device is operated to make the pick-up device operate in a negative pressure state, and the take-out operation is performed, and under the action of the negative pressure, the storage in the storage tank 1 is The suction is taken to the pick-up device, and then the feces are removed using the pick-up device. When the above-described escaping process is completed, the faecal interface device of the pick-up device is not removed from the toilet connector 5 first. In this way, the negative pressure working state of the negative pressure take-up tube and the pick-and-place device of the present invention is maintained, that is, if the negative pressure working state is not terminated or is not suspended, the first will be The toilet valve 7 is closed, and water is again injected into the fluid hopper 4 so that at least the valve front portion of the pilot valve 2 of the fluid connection passage 3 is filled, and then the inlet valve 2 is opened. At this time, under the action of the external air pressure, the fluid connection channel 3, or the water in the fluid bucket 4, flows through the pipe tee 6, the toilet connector 5, and the pick-up device. After the interface device, the access pipe of the pick-up device is quickly entered. Due to the shut-off of the toilet valve 7 and the negative pressure working state of the pick-up device, a pressure difference occurs between the tail end of the drain pipe and the opening of the fluid bucket 4, and in addition to the external air pressure, the fluid bucket 4 The added water quickly enters the draining pipe to clean up the accumulated feces in the pipe. Specifically, before the inlet valve 2 is opened, due to the closing of the outlet valve 7, the front end of the retort conduit is closed, and the faeces in the defecating pipeline lose the pressure difference and cannot continue to enter the body of the sluice device. Become a pipeline. Moreover, since the viscosity of the pipe accumulating itself is greater than that of water, the front end of the water that quickly enters the pipe is inevitably blocked by the pipe accumulation to form a water plug; the incompressibility of the water plug and the end of the pipe And the pressure difference between the opening of the fluid bucket 4, the water plug is pushed by the rear air, and the work of draining the pipeline will continue to push the work into the body of the pick-up device, thereby realizing the elimination of the toilet tube surplus, and In addition, since the water can simultaneously clean the inner wall of the pipe, the tube of the pipe can be cleaned to obtain a more ideal cleaning effect. In other embodiments, it is also possible to form a gas pressure in the fluid hopper 4 and the fluid connection passage 3 by means of the gas without adding water to the fluid hopper 4. Specifically, when the above operation is performed without adding water to the fluid bucket 4, a gas plug will be formed in the tail portion of the pipe trunk in the pipe of the pick-up device; for the same reason, the gas plug acts, the pipe balance It will continue to be pushed into the body of the pick-up device, and the same can be achieved. Therefore, Figure 1 is also a schematic diagram of the mechanism for the negative pressure of the negative pressure to take up the waste pipe. The cleaning effect of the air plug on the inner wall of the pipe is not as good as that of the water. Therefore, the negative pressure of the air pipe is used to remove the pipe, and the cleaning mechanism is more effective than the water plug. The negative pressure is taken from the pipe and the pipe is cleaned. Secondly, the implementation of the gas plug action negative pressure take-up tube balance is eliminated, and it is not necessary to apply water filling to the fluid bucket 4, in which case the setting of the fluid bucket 4 is unnecessary. Referring to FIG. 2, the second embodiment of the negative pressure tube residual cleaning mechanism of the present invention is different from the first embodiment in that: the second embodiment of the negative pressure tube residual cleaning mechanism of the present invention further includes A water tank 11, a water supply passage 10 connecting the water tank 11 and the fluid bucket 4, and a water supply valve 9 installed on the water supply passage 10. Preferably, the water tank 11 is a toilet water tank. The water supply valve 9 is located between the water tank 11 and the fluid hopper 4 to control the on and off of the water supply of the water tank 11 to the fluid hopper 4. In this way, the water filling of the fluid bucket 4 is taken from the water tank 11, and is controlled by the provided water supply valve 9 and the water supply passage 10; Referring to FIG. 3, the third embodiment of the negative pressure tube residual cleaning mechanism of the present invention The difference between the mode and the second embodiment is that: the third embodiment of the negative pressure tube accumulation cleaning mechanism of the present invention eliminates the water tank 11, but directly connects the water supply passage 10 with the external pipe, thereby passing through the outside. The pipe bow I water supplies water to the fluid bow I bucket 4. The water supply valve 9 controls the opening and closing of the water supply to the fluid hopper 4 by the external pipe. Thus, the difference between FIG. 3 and FIG. 2 is that the water plug acts on the negative pressure take-up tube to accumulate the cleaning mechanism, and the water filling of the fluid bucket 4 is controlled by the provided water supply valve 9 and the water supply passage 10, and the water supply pipe is provided. The water of 12 is taken from an external pipe. Fig. 2 and Fig. 3 except that the water injection operation in the fluid bucket 4 is different from the water injection shown in Fig. 1, the other conveniences and the tube accumulation are eliminated, and the operation process is the same as that in Fig. 1. The toilet valve 7, the pilot valve 2, or the water supply valve 9 is taken as a manual valve, or is taken as a self-control valve controlled by a program; the self-control valve controlled by the setting program is operated according to the pick-up device. The state implements an automatic on/off operation, which makes the tube accumulation easier and faster. The sump is also specifically provided with an air passage for supporting the negative pressure, but is not shown in the drawings. The structure of the negative pressure tube accumulation and elimination mechanism of the utility model has a single structural state, and during the process of removing the accumulated storage space in the interface device for taking and consuming the pipe, there is no positive pressure entering the storage tank 1 Therefore, it is not necessary to carry out special pressure treatment for the storage tank 1, and the operation safety of the storage tank 1 and other equipment connected to the storage tank 1 can be ensured; Negative pressure, there will be no outward diffusion of accumulated odor in the storage tank 1; in addition, the use of negative pressure to take the toilet and the implementation of the tube balance will not require the removal of the device. Adding specialized agencies; The auxiliary negative pressure-receiving tube surplus cleaning mechanism for the storage facilities has the characteristics of simple structure, low cost and easy operation. The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
