Technical Field

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

[0002] Electric sprayers are powered by batteries to drive a water pump, which atomizes medicine or other liquids and sprays them evenly onto objects. A filter is installed at the bottom of the water inlet pipe to filter the liquid stored inside the sprayer, preventing clogging of the nozzles.

[0003] Since the water inlet pipe of the electric sprayer lacks a valve to control the on / off state, a leak-proof valve can be installed between the filter and the water supply pipe to prevent water leakage when the electric sprayer is not started. The leak-proof valve is connected to the filter via a hose, which is cumbersome to install and easy to fall off. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure between the filter element and the leak-proof valve of an electric sprayer, so as to solve the problems of cumbersome installation and operation and easy detachment of the leak-proof valve and filter element on existing electric sprayers.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a connection structure between an electric sprayer filter element and a leak-proof valve, comprising:

[0006] A filter element, on which a first connector tube is provided;

[0007] The leak-proof valve includes a valve body, a spring, a ball, and a housing. The housing is provided with a connector, which is inserted into the first connector pipe. The valve body is fixedly installed inside the housing. The spring is located inside the valve body. One side of the ball contacts the spring, and the opposite side blocks the connector. The end of the valve body is inserted and fixed to the water supply pipe of the sprayer.

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

[0009] The end of the connector tube is provided with two symmetrically arranged fastening plates. The end of the fastening plate is provided with an inverted part, which passes through the first connector tube and fastens to the inner wall of the filter element.

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

[0011] A rubber ring is provided between the sphere and the shell, with one side of the rubber ring contacting the sphere and the other side contacting the shell.

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

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

[0015] The valve body is provided with several circumferentially arranged ribs, and the top of the ribs is provided with an arc-shaped guide surface.

[0016] As a further description of the above technical solution:

[0017] The valve body has annular raised ribs on the outside.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, a leak-proof valve is arranged between the water supply pipe and the filter element of the electric sprayer. One end of the leak-proof valve is connected to the filter element through the housing, and the other end is connected to the water supply pipe. When the electric sprayer is not started, the spring inside the leak-proof valve presses against the ball, causing the ball to block the first connector pipe for liquid inlet on the housing, preventing liquid from entering the water supply pipe and avoiding water leakage when the electric sprayer is not started.

[0020] 2. In this utility model, the leak-proof valve does not require a rubber tube and can be directly installed on the filter element, simplifying the installation steps. After the insertion tube and the first connector tube are inserted into place, the inverted part prevents the insertion tube from falling back and detaching from the filter element, making it less likely to fall off.

[0028] 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.

[0029] Example 1

[0030] Please see Figure 1-4 This utility model provides a technical solution: a connection structure between a filter element and a leak-proof valve in an electric sprayer, comprising:

[0031] Filter element 1, on which a first connector tube 11 is provided;

[0032] The leak-proof valve 3 includes a valve body 31, a spring 32, a ball 33, and a housing 39. A connector 391 is provided on the housing 39. The connector 391 is inserted into the first connector pipe 11. The valve body 31 is fixedly installed in the housing 39. The spring 32 is provided in the valve body 31. One side of the ball 33 contacts the spring 32, and the opposite side blocks the connector. The end of the valve body 31 is inserted and fixed to the water supply pipe of the sprayer.

[0033] A rubber ring 34 is provided between the ball 33 and the shell 39. One side of the rubber ring 34 contacts the ball 33 and the other side contacts the shell 39, which improves the sealing quality and effectively enhances the water-stopping and leak-proof effect of the leak-proof valve 3.

[0034] The valve body 31 is provided with a second connector pipe 35 at the bottom, and a conical boss 351 is provided on the second connector pipe 35 to facilitate the connection and fixation of the leak-proof valve 3 to the water supply pipe of the sprayer.

[0035] The valve body 31 has an annular rib 37 on its outer side. The valve body 31 can be fixedly installed in the housing 39 by interference fit or ultrasonic welding. When the valve body 31 is assembled by interference fit, the annular rib 37 can effectively improve the connection strength and prevent loosening.

[0036] Working Principle: A leak-proof valve 3 is installed between the water supply pipe of the electric sprayer and the filter element 1. One end of the leak-proof valve 3 is connected to the filter element 1 through the housing 39, and the other end is connected to the water supply pipe. When the electric sprayer is not running, the spring 32 inside the leak-proof valve 3 presses against the ball 33, causing the ball 33 to block the first connector pipe 11 for liquid inlet on the housing 39, preventing liquid from entering the leak-proof valve 3 and the water supply pipe, thus preventing water leakage when the electric sprayer is not running. When the electric sprayer is running, a negative pressure is generated in the water supply pipe of the sprayer. Under the action of the pressure difference, the spring 32 is squeezed back, and the ball 33 releases the blockage on the connector pipe 391, realizing normal water supply. The leak-proof valve does not require a rubber hose and is directly installed on the filter element, simplifying the installation steps. After the connector pipe and the first connector pipe are inserted into place, the inverted part prevents the connector pipe from retracting and detaching from the filter element, making it less likely to fall off.

[0037] Example 2

[0038] Based on the above embodiments, the following improved technical solutions are further made in this embodiment: two fastening plates 3911 are symmetrically arranged at the end of the insertion tube 391, and the end of the fastening plate 3911 is provided with a buckle part 3912. The buckle part 3912 passes through the first connector tube 11 and is fastened to the inner wall of the filter element 1.

[0039] The insertion tube 391 forms two separate fastening plates 3911 at its end through a notch extending inward from the end face, so as to facilitate the insertion tube 391 to be inserted and fastened with the first connector tube 11. After being inserted into place, the inverted part 3912 prevents the insertion tube 391 from retracting and disengaging from the filter element 1.

[0040] Example 3

[0041] Based on the above embodiments, this embodiment further improves upon the following technical solution: a plurality of circumferentially arranged ribs 36 are provided inside the valve body 31, and an arc-shaped guide surface 361 is provided on the top of the ribs 36.

[0042] Rib 36 is used to support and position spring 32, while the arc-shaped guide surface 361 at the top of rib 36 limits the stroke of ball 33.

[0043] 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.
