Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waterproof technology for electric sprayer handles, and particularly relates to a waterproof structure for an electric sprayer handle. Background Technology
[0002] In existing electric sprayer designs, the handle shell is usually assembled by splicing the two halves vertically, but this method has significant shortcomings in waterproofing. Because it is often difficult to completely seal the seams of the handle shell, and environmental factors may affect it during use, moisture can easily seep into the interior of the handle shell through the seams.
[0003] Once moisture enters the handle's casing, it can damage internal electronic components and batteries, causing malfunctions or short circuits. It can also lead to corrosion and other problems, severely impacting the handle's lifespan and overall performance. Furthermore, accidental contact with a damp handle can pose a risk of electric shock, reducing safety during use.
[0004] However, if it is designed as a one-piece molded structure, electronic components are difficult to install and cannot be disassembled, making it inconvenient for later maintenance. Utility Model Content
[0005] The purpose of this utility model is to address the problem that existing electric sprayer handle shells are usually assembled by splicing them together in a vertically split manner. While this structure may be relatively simple to assemble, it has significant shortcomings in waterproof performance. Since it is often difficult to completely seal the seams of the handle shell, and environmental factors may affect the use of the product, moisture can easily seep into the interior of the handle shell through the seams, affecting the safety of use. Therefore, this utility model proposes a waterproof structure for electric sprayer handles.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof structure for an electric sprayer handle, comprising a cylindrical first mounting shell and a second mounting shell, wherein the first mounting shell is provided with an inwardly recessed connecting surface, and the second mounting shell is provided with a notched abutting surface, and a sealing ring is provided between the connecting surface and the notched abutting surface, the first mounting shell and the second mounting shell forming a mounting groove, and the battery, water pump and water delivery pipe are all located in the mounting groove.

[0040] Please see Figure 1-6 This utility model provides a technical solution: a waterproof structure for an electric sprayer handle, including a cylindrical first mounting shell 1 and a second mounting shell 2. The first mounting shell 1 is provided with an inwardly recessed connecting surface 3, and the second mounting shell 2 is provided with a notched abutting surface 4. A sealing ring 5 is provided between the connecting surface 3 and the notched abutting surface 4. The first mounting shell 1 and the second mounting shell 2 form a mounting groove 6, and the battery 7, water pump 8 and water pipe 9 are all located in the mounting groove 6.
[0041] A fixing groove 10 is provided on the connecting surface 3, and the sealing ring 5 is connected in the fixing groove 10.
[0042] A button 13 mounting groove 11 is provided on the connecting surface 3, and a waterproof adhesive backing 12 is provided in the button 13 mounting groove 11. The button 13 is attached to the waterproof adhesive backing 12. This improves the waterproofness of the button hole.

[0048] Several connecting blocks extend inward to the periphery of the battery, ensuring the stability of the batteries within the handle housing.
[0049] The structure of this utility model is not limited to providing a connecting surface on the first mounting shell and a notched abutting surface inside the second mounting shell. Alternatively, a notched abutting surface can be provided on the first mounting shell and a connecting surface on the second mounting shell, with the notched abutting surface and the connecting surface sealed by a sealing ring.
[0050] Working principle: The handle shell is designed as a horizontally spliced first and second mounting shell. The connection between the first and second mounting shells is set into a regular, evenly stressed cylindrical shape with a certain length of connection surface. A sealing ring is placed in the middle of the connection to improve the sealing performance. At the same time, waterproof adhesive is applied to the bottom of the button and a sealing plug is placed on the charging port, thus achieving complete waterproofing. Compared with the previous one-piece structure and vertical splicing structure, this structure is not only easier to disassemble and repair, but also, compared with the traditional vertical connection, the horizontal connection of this structure, together with the sealing ring, has a smaller exposed area, better sealing performance, better waterproof effect, and improved safety during use.
[0051] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
