Specific implementation method:

[0026] The present invention is further described below with reference to specific embodiments. Figure 1 —7:

[0027] The utility model provides a peristaltic pump foam shield, which comprises an upper shell 1 and a lower shell 2. The upper shell 1 and the lower shell 2 are sealed and connected to form a foaming agent chamber 3. A liquid adding port 4 communicating with the foaming agent chamber 3 is arranged on the upper shell 1, and a liquid outlet 5 communicating with the foaming agent chamber 3 is arranged on the lower shell 2. A peristaltic pump 6 is arranged at the bottom of the lower shell 2. The inlet of the peristaltic pump 6 is connected with the liquid outlet 5 of the foaming agent chamber 3 through a first pipe 7, and the outlet is connected with a second pipe 8. The second pipe is respectively connected with a water pipe and a foaming head through a three-way joint 8.

[0028] The working principle of the utility model is:

[0029] Add a proper amount of foaming agent into the foaming agent chamber 3 through the liquid adding port 4. The peristaltic pump starts to work, extracts the foaming agent in the foaming agent chamber 3 through the first pipe 7 and transports it through the second pipe 8, and then mixes it with the water in the tap water pipe, and absorbs air in the air through the foaming head to generate foam and spray it into the toilet.

[0030] It should be noted that the foaming head utilizes the principle of Venturi to generate foam. The foaming head can be purchased directly from the market, and the utility model itself does not describe its structure in detail.

[0031] The peristaltic pump 6 is a liquid delivery device that can achieve high-precision flow control by controlling the driver speed and the hose with different flow rates. Therefore, compared with the liquid suction pump in the prior art, the utility model can accurately control the liquid suction volume, control the liquid suction volume within 1ml, and use less liquid.

[0032] Furthermore, the utility model also provides a foaming agent overflow port 9 on the upper shell 1 which is connected with the foaming agent chamber 3 .

[0033] Generally speaking, the upper shell 1 and the lower shell 2 are connected by ultrasonic welding. Of course, a sealing ring combined with a buckle or the like can also be used for sealing connection.

[0034] It should be noted that a peristaltic pump installation cavity 10 is formed by the upward protrusion of the bottom surface of the lower housing 2 of the present utility model. A first peristaltic pump card slot 11 is provided on the top surface of the peristaltic pump installation cavity 10. A wire 12 is connected to the peristaltic pump 6. A bottom cover 13 that covers the peristaltic pump 6, the first pipeline 7, the second pipeline 8, and the wire 12 is detachably provided on the bottom surface of the lower housing 2. A second peristaltic pump card slot 14 is provided on the bottom cover 13. The peristaltic pump is clamped between the first peristaltic pump card slot 11 and the second peristaltic pump card slot 14. The first peristaltic pump card slot 11 and the second peristaltic pump card slot 14 can limit the peristaltic pump 6 to prevent it from generating displacement. The setting of the bottom cover 13 also covers the first pipeline 7, the second pipeline 8, and the wire 12, making the product more tidy and improving the quality of the product.

[0035] As described above, the bottom cover 13 is detachably connected to the lower housing 2. Specifically, several elastic buckles 15 extend downward from the bottom surface of the lower housing 2. Hooks are provided at the lower ends of the elastic buckles 15. The hooks of the elastic buckles 15 are buckled on the bottom surface of the bottom cover 13. This connection method is convenient and firm for disassembly and assembly.

[0036] In order to improve the heat dissipation effect or facilitate observing the internal situation of the bottom cover 13, several strip-shaped through holes 16 are provided on the bottom cover 13 of the present utility model. The distribution positions of the strip-shaped through holes 16 are set according to the actual situation.

[0037] The present utility model also provides a positioning buckle 17 on the bottom surface of the lower housing 2 for positioning the second pipeline 8 and the wire 12. The second pipeline 8 and the wire 12 are clamped on the corresponding positioning buckles 17. In this way, the positions of the second pipeline 8 and the wire 12 on the lower housing 2 are positioned, and the wiring is clean and tidy.

[0038] In addition, the present utility model provides a mutually connected channel 18 on one side of the upper housing 1 and the lower housing 2. The channel 18 is independent of the foaming agent cavity 3. One end of the second pipeline 8 and the wire 12 extends out of the upper housing 1 through the channel 18. With this structure, the wiring is hidden, and the structure is compact and clean.

[0039] In order to facilitate the installation of the present utility model, installation lugs 19 for installation are provided on the upper housing 1. The present utility model is fixed at the corresponding position of the intelligent toilet through the cooperation of the installation lugs 19 and screws.

[0040] As can be seen from the above, the peristaltic pump of the present utility model is installed on the bottom surface of the lower housing 2, with a compact structure and a hidden wiring making the whole clean and tidy.

[0041] The above embodiments are only one of the preferred embodiments of the present utility model, and do not limit the implementation scope of the present utility model. Therefore, all equivalent changes made according to the shape, structure, and principle of the present utility model should be covered within the protection scope of the present utility model.
