Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a waterproof control structure for household appliances. Background Technology

[0002] Household appliances refer to various electrical and electronic appliances used in homes and similar places. These include refrigeration appliances, air conditioners, cleaning appliances, kitchen appliances, electric heating appliances, beauty and health appliances, and audio-visual appliances, etc. Different household appliances all require plugs for electrical connection. The plug is an important component that connects the electrical product to the power source. It ensures the safe transmission of current and enables the equipment to work properly. Plugs are usually made of metal conductors and insulating materials.

[0003] While existing plugs offer numerous advantages, they still suffer from several drawbacks. They lack adequate waterproofing of the conductive rod, meaning that when a wet hand inserts the plug, liquid adheres to the outside of the conductive rod and can then enter the socket. Since liquid is conductive, this can cause a short circuit, resulting in poor plug safety. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a waterproof control structure for household appliances.

[0005] The technical solution adopted by this utility model to solve its technical problem is a waterproof control structure for household appliances, including a plug body, a waterproof cover, and a protective tube. Conductive rods are provided on both outer walls of the plug body, and slide rails are installed on both outer walls of the plug body. A slide groove is opened on one side of the outer wall of the slide rail, and an movable hole is opened on one side of the inner wall of the slide groove. A waterproof cover is provided on the outside of the plug body, and limit blocks are installed on both sides of the inside of the waterproof cover. A connecting rod is installed on one outer wall of the limit block, and a protective tube is inserted into both outer walls of the waterproof cover.

[0006] By adopting the above technical solution, the protective cover shields and protects the plug body and conductive rod, preventing liquid adhesion to the conductive rod when not in use. This effectively prevents moisture from entering the plug body, ensuring the safe use of household appliances. Furthermore, the protective tube shields the conductive rod, preventing it from being struck by external objects when not in use, ensuring its flatness and extending its lifespan. Additionally, by preferentially inserting the protective tube into the socket's hole, the insertion trajectory of the conductive rod is restricted, reducing the risk of damage to the socket's interior.

[0007] Specifically, an electrical wire is inserted and installed on the lower outer wall of the plug body, and the electrical wire is electrically connected to the conductive rod.

[0008] By adopting the above technical solution, the plug body pushes the conductive rod into the socket hole, and the household appliances are powered and operated normally through the wire, ensuring the normal transmission of current and avoiding safety hazards caused by poor wire contact.

[0009] Specifically, a sealing ring is fixedly attached to one side of the inner wall of the waterproof cover, and the inner ring of the sealing ring is in contact with the outer wall of the plug body.

[0010] By employing the above technical solution, the tight contact between the sealing ring and the outer wall of the plug body effectively prevents moisture from seeping in through gaps. This design improves the sealing performance and reliability of the waterproof structure.

[0011] Specifically, the limiting block adopts a rectangular shape design, the size of the limiting block is smaller than the inner wall size of the slide groove, and the limiting block is located inside the slide groove.

[0012] By adopting the above technical solution, the limiting block and the sliding groove can ensure the stable installation of the waterproof cover on the plug body and ensure that the movement trajectory of the protective cover on the outside of the plug body is controlled. This design prevents the waterproof cover from shaking or falling off the plug body, thereby improving the stability and safety of the waterproof structure.

[0013] Specifically, the outer diameter of the connecting rod is smaller than the inner diameter of the movable hole, and the connecting rod is located inside the movable hole.

[0014] By adopting the above technical solution, the connecting rod can move freely within the movable hole. This design allows the waterproof cover to be adjusted and fixed to a certain extent on the plug body, thereby ensuring the flexibility and adaptability of the waterproof structure.

[0015] Specifically, a spring is provided on one side of the outer wall of the connecting rod, and the inner wall of the waterproof cover is elastically connected to the slide rail through the spring.

[0016] By adopting the above technical solution, the stability of the waterproof cover can be increased, and it can also buffer external impacts to a certain extent, protecting the plug body from damage. In addition, the spring can push the waterproof cover back to its original position when it is not in use, ensuring the relative position of the waterproof cover on the outside of the plug body is stable.

[0017] Specifically, a silicone ring is fixedly attached to the inner wall of the protective tube, the conductive rod is located inside the silicone ring, and a material outlet is opened on the outer wall of the silicone ring.

[0018] By adopting the above technical solution, the silicone ring can further prevent moisture from entering the conductive rod area. The softness and elasticity of the silicone ring allow it to fit tightly against the conductive rod, thereby improving the waterproof effect. At the same time, the material passage on the outer wall of the silicone ring allows the conductive rod to pass through without compromising the waterproof performance of the silicone ring. After the waterproof cover is reset, the elasticity of the silicone ring allows it to deform and reset, thus achieving a sealed shielding of the protective tube again. This design not only ensures the waterproof effect but also facilitates the connection between the conductive rod and the socket.

[0019] The beneficial effects of this utility model are:

[0020] (1) The waterproof control structure for household appliances described in this utility model provides shielding and protection for the plug body and conductive rod, preventing liquid from adhering to the conductive rod when not in use, effectively preventing moisture from entering the plug body and ensuring the safe use of household appliances.

[0021] (2) The waterproof control structure for household appliances described in this utility model can shield the conductive rod, prevent the conductive rod from being hit by external objects when it is not in use, ensure the flatness of the conductive rod, improve the service life of the conductive rod, and limit the insertion trajectory of the conductive rod by preferentially inserting the protective tube into the socket hole, thereby reducing the damage of the conductive rod to the inside of the socket.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the waterproof control structure for household appliances of this utility model includes a plug body 1, a waterproof cover 2, and a protective tube 25. Conductive rods 11 are provided on both outer walls of the plug body 1, and slide rails 13 are installed on both outer walls of the plug body 1. A slide groove 14 is opened on one side of the outer wall of the slide rail 13, and an movable hole 15 is opened on one side of the inner wall of the slide groove 14. The waterproof cover 2 is provided on the outside of the plug body 1. Limiting blocks 21 are installed on both sides of the inside of the waterproof cover 2. A connecting rod 22 is installed on one outer wall of the limiting block 21. The protective tube 25 is inserted and installed on both outer walls of the waterproof cover 2.

[0030] During use, the protective cover shields the plug body 1 and the conductive rod 11, preventing liquid adhesion to the conductive rod 11 when not in use. This effectively prevents moisture from entering the plug body, ensuring the safe use of household appliances. The protective tube 25 also shields the conductive rod 11, preventing it from being bumped by external objects when not in use, ensuring the flatness of the conductive rod 11, and extending its service life. Furthermore, by preferentially inserting the protective tube 25 into the socket hole, the insertion trajectory of the conductive rod 11 is restricted, reducing the risk of damage to the socket.

[0031] For the circuit to be connected, for example, such as Figure 2 As shown, a wire 12 is inserted and installed on the lower outer wall of the plug body 1, and the wire 12 is electrically connected to the conductive rod 11.

[0032] When in use, the plug body 1 pushes the conductive rod 11 into the socket hole, and the household appliances are powered and operated normally through the wire 12, ensuring normal current transmission and avoiding safety hazards caused by poor contact of the wire 12.

[0033] For sealing, exemplarily, such as Figure 3 As shown, a sealing ring 24 is fixedly attached to one side of the inner wall of the waterproof cover 2, and the inner ring of the sealing ring 24 is in contact with the outer wall of the plug body 1.

[0034] During use, the tight contact between the sealing ring 24 and the outer wall of the plug body 1 effectively prevents moisture from seeping in through gaps. This design improves the sealing performance and reliability of the waterproof structure.

[0035] To limit the distance of movement, for example, such as Figure 3 As shown, the limiting block 21 adopts a rectangular shape design. The size of the limiting block 21 is smaller than the inner wall size of the slide groove 14, and the limiting block 21 is located inside the slide groove 14.

[0036] During use, the limiting block 21 and the sliding groove 14 can ensure the stable installation of the waterproof cover 2 on the plug body 1 and ensure that the movement trajectory of the protective cover on the outside of the plug body 1 is controlled. This design prevents the waterproof cover 2 from shaking or falling off on the plug body 1, thereby improving the stability and safety of the waterproof structure.

[0037] For relative motion stability, for example, such as Figure 3 As shown, the outer diameter of the connecting rod 22 is smaller than the inner diameter of the movable hole 15, and the connecting rod 22 is located inside the movable hole 15.

[0038] During use, the connecting rod 22 can move freely within the movable hole 15. This design allows the waterproof cover 2 to be adjusted and fixed to a certain extent on the plug body 1, thereby ensuring the flexibility and adaptability of the waterproof structure.

[0039] For reset, exemplarily, such as Figure 3 As shown, a spring 23 is provided on the outer wall of one side of the connecting rod 22, and the inner wall of the waterproof cover 2 is elastically connected to the slide rail 13 through the spring 23.

[0040] When in use, it can increase the stability of the waterproof cover 2, and at the same time, it can buffer external impacts to a certain extent, protect the plug body 1 from damage, and the spring 23 can push the waterproof cover 2 to reset when it is not in use, ensuring that the relative position of the waterproof cover 2 on the outside of the plug body 1 is stable.

[0041] For sealing and protection, exemplarily, such as Figure 4 As shown, a silicone ring 26 is fixedly attached to the inner wall of the protective tube 25, the conductive rod 11 is located inside the silicone ring 26, and a material outlet is opened on the outer wall of the silicone ring 26.

[0042] During use, the silicone ring 26 further prevents moisture from entering the conductive rod 11 area. The softness and elasticity of the silicone ring 26 allow it to fit tightly against the conductive rod 11, thereby improving the waterproof effect. At the same time, the material passage on the outer wall of the silicone ring 26 allows the conductive rod 11 to pass through without compromising the waterproof performance of the silicone ring 26. After the waterproof cover 2 is reset, the elasticity of the silicone ring 26 causes it to deform and reset, thus achieving a complete seal and shielding of the protective tube 25. This design not only ensures the waterproof effect but also facilitates the connection between the conductive rod 11 and the socket.

[0043] In use, before normal use, the waterproof cover 2 is securely attached to the plug body 1 via the elastic connection between the spring 23 and the slide rail 13. The sealing ring 24 and the silicone ring 26 respectively ensure the waterproof performance of the plug body 1 and the conductive rod 11 area. As needed, the position of the waterproof cover 2 on the plug body 1 can be adjusted by moving the position of the connecting rod 22 in the movable hole 15.

[0044] When the plug body 1 is inserted into the socket, the protective tube 25 is allowed to enter the socket hole first. This restricts the insertion trajectory of the conductive rod 11. As the plug body 1 is pushed in further, the conductive rod 11 will pass through the silicone ring 26 and the socket hole, achieving electrical connection with the socket.

[0045] After use, pull the plug body 1 out of the socket. At this time, the conductive rod 11 will first detach from the socket hole. After pulling out the plug body 1, the spring force of the spring 23 will push the waterproof cover 2 back to its original position, ensuring that the plug body 1 and the conductive rod 11 are completely covered again.

[0046] It should be noted that this utility model is a waterproof control structure for household appliances. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
