Technical Field

[0001] This utility model relates to the field of electric sprayer technology, and in particular to a leak-proof design for an electric sprayer filter. Background Technology

[0002] Electric sprayers are powered by batteries to drive a water pump, turning medicine or other liquids into a mist that is then sprayed evenly onto other objects.

[0003] To prevent leaks, electric sprayers need to integrate the leak-proof function into the water pump, which results in high water pump costs and inconvenient maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a leak-proof water-stopping filter for electric sprayers, so as to solve the problems of high water pump cost and inconvenient maintenance of existing electric sprayers.

[0006] The filter module has a connecting seat that extends into itself, and the bottom surface of the connecting seat has a through hole.

[0007] The leak-proof module includes a valve body and a connector tube. The valve body is inserted into the connector seat. The valve body has an annular rib on its side wall, which contacts the inner wall of the connector seat. The connector tube extends out of the filter module and has a conical boss on its outer side. The connector tube is used to connect to the sprayer's water inlet pipe.

[0008] As a further description of the above technical solution:

[0009] The end of the connector is provided with a conical enlarged section.

[0010] As a further description of the above technical solution:

[0011] The leak-stopping module also includes an elastic element and a sealing element. The elastic element is located inside the valve body, and the sealing element is located between the elastic element and the through hole. One side of the sealing element contacts the elastic element, and the other side contacts the wall of the through hole.

[0012] As a further description of the above technical solution:

[0013] A rubber sealing ring is provided between the plug and the through hole.

[0014] As a further description of the above technical solution:

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the filter element of the electric sprayer integrates filtration and leak prevention functions. The connection structure between the leak prevention module and the filter module can be hidden inside the filter module, which effectively improves the connection reliability and eliminates the need for a water pump with integrated leak prevention function, thereby reducing the cost of the electric sprayer water pump and facilitating maintenance.

[0018] 2. In this utility model, the valve body of the leak-proof module is fixed to the connecting seat by an interference fit, and the connection strength is further improved by extrusion deformation using annular ribs. In addition, the bottom of the side wall of the valve body is thickened to improve its resistance to deformation, and the annular ribs are set on the thickened area of ​​the valve body side wall to improve the firmness of the interference fit assembly of the valve body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-3 This utility model provides a technical solution: a leak-proof water-stopping filter element for an electric sprayer, comprising:

[0028] The filter module 1 has a connecting seat 11 extending into itself, and a through hole 111 is provided on the bottom surface of the connecting seat 11.

[0029] Leak-stopping module 2 includes a valve body 21 and a connector tube 22. The valve body 21 is inserted into the connector seat 11. An annular rib 211 is provided on the side wall of the valve body 21. The annular rib 211 contacts the inner wall of the connector seat 11. The connector tube 22 extends out of the filter module 1. A conical boss 221 is provided on the outer side of the connector tube 22. The connector tube 22 is used to connect to the sprayer inlet pipe. The conical boss 221 facilitates the connection and assembly of the connector tube 22 and the sprayer inlet pipe.

[0030] The connection structure between the leak-stopping module 2 and the filter module 1 is hidden inside the filter module 1, effectively improving connection reliability and effectively controlling the overall length of the filter element, making it easy to remove or place the filter element from the sprayer body during subsequent use of the electric sprayer. The valve body 21 of the leak-stopping module 2 is inserted and fixed to the connecting seat 11 by an interference fit, and the connection strength is further improved by the extrusion deformation of the annular rib 211.

[0031] The leak-stopping module 2 also includes an elastic element 23 and a sealing element 24. The elastic element 23 is disposed inside the valve body 21, and the sealing element 24 is disposed between the elastic element 23 and the through hole 111. One side of the sealing element 24 contacts the elastic element 23, and the other side contacts the wall of the through hole 111. A rubber sealing ring 25 is provided between the sealing element 24 and the through hole 111. The sealing element 24 and the connecting seat 11 achieve flexible contact through the rubber sealing ring 25, thereby improving the sealing effect.

[0032] An annular boss 112 is provided on the bottom surface of the connecting seat 11. The rubber sealing ring 25 is fitted on the outside of the annular boss 112 to effectively position the rubber sealing ring 25 and improve the leak-proof effect.

[0033] Working principle: The filter element of the electric sprayer integrates filtration and leak-proof functions. The connection structure between the leak-proof module 2 and the filter module 1 can be hidden inside the filter module 1, effectively improving connection reliability. Furthermore, it eliminates the need for a water pump with integrated leak-proof function, reducing the cost of the electric sprayer's water pump and facilitating maintenance. The valve body 21 of the leak-proof module 2 is inserted and fixed to the connecting seat 11 via an interference fit, and the connection strength is further enhanced by the compression deformation of the annular rib 211.

[0034] Furthermore, for filter module 1 with insufficient thickness, the connecting seat 11 can extend outward to facilitate the installation of leak-stopping module 2. Although leak-stopping module 2 protrudes from filter module 1 and does not achieve a hidden connection structure, the overall length of the filter element is limited, which does not affect ease of use.

[0035] Example 2

[0036] Based on the above embodiments, this embodiment further improves upon the following technical solution: the thickness of the side wall of the valve body 21 gradually decreases from the bottom to the top.

[0037] The bottom of the side wall of the valve body 21 is thickened to improve its resistance to deformation, and the annular ribs 211 are provided on the side wall of the valve body 21 in the thickened area to improve the firmness of the interference fit assembly of the valve body 21.

[0038] Example 3

[0039] Based on the above embodiments, this embodiment further improves upon the following technical solution: a conical enlarged hole section 12 is provided at the end of the connecting seat 11.

[0040] When the valve body 21 is inserted into the connecting seat 11, the enlarged section 12 facilitates the insertion of the valve body 21 into the connecting seat 11, thus improving assembly convenience.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
