Description

Technical Field

[0001] This utility model relates to the field of junction boxes, and in particular to a moisture-proof junction box for water pumps. Background Technology

[0002] The junction box on a water pump is a crucial component connecting the power supply and the motor, providing a safe and reliable circuit connection and protecting the circuitry from damage. However, when the water pump operates in a humid environment, ambient moisture can enter the junction box, causing it to become damp. Existing junction boxes lack a moisture-absorbing structure; the moisture condenses inside, contacting the internal circuit board and causing corrosion, thus affecting its lifespan.

[0003] To address the aforementioned problems, we propose a moisture-proof junction box for water pumps. Utility Model Content

[0004] The purpose of this invention is to provide a moisture-proof junction box for water pumps, which has the advantage of being moisture-proof.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a moisture-proof junction box for a water pump, comprising a box body, two placement nets fixedly connected to the bottom of the inner cavity of the box body, a cloth bag provided inside the placement net, and the cloth bag filled with moisture-absorbing material; external connecting pipes are connected to both sides of the box body, and an internal connecting member threadedly connected to the box body is provided inside the external connecting pipe, a silicone sleeve fixedly connected inside the internal connecting member, and lubricating oil provided inside the silicone sleeve.

[0006] By adopting the above technical solution, the moisture entering the box can be absorbed by setting up a mesh, cloth bag and moisture-absorbing material, thereby keeping the inside of the box dry; by setting up internal connectors, silicone sleeve and lubricating oil, the wiring can be sealed after installation, increasing the waterproof sealing of the junction box.

[0007] The present invention is further configured such that: a circuit board is installed at the bottom of the inner cavity of the box, and wires are electrically connected to both sides of the circuit board.

[0008] By adopting the above technical solution, a wire is set up to connect with the water pump, and the signal transmission function is realized by transmitting signals to the water pump through the wire.

[0009] The present invention is further configured such that: the lubricating oil is wrapped around the surface of the wire, and the lubricating oil is filled inside the silicone sleeve.

[0010] The above technical solution uses lubricating oil to lubricate the wires and also to seal the surface of the wires and the silicone sleeve.

[0011] The present invention is further configured such that the surface of the wire is in sealed contact with the inner wall of the silicone sleeve.

[0012] Using the above technical solution, the silicone sleeve is tough, and the inner diameter of the end of the silicone sleeve facing the inner wall of the box is smaller than the diameter of the wire. By passing the wire through the inner wall of the lubricating oil, the silicone sleeve can be forcibly squeezed. The wire can pass through the inside of the silicone sleeve, and the inner wall of the end of the silicone sleeve near the inside of the box will be tightly attached to the surface of the wire to form a seal.

[0013] The present invention is further configured such that: the top of the box body is provided with a box cover, and the inside of the box cover is threaded with a fixing screw that is threadedly connected to the box body.

[0014] The above technical solution uses a lid to seal the top of the box, and screws to securely connect the box and the lid.

[0015] The present invention is further configured such that the moisture-absorbing material is specifically quicklime.

[0016] Using the above technical solution, quicklime has strong water absorption and moisture absorption properties, which can effectively remove moisture. After absorbing moisture from the air, quicklime will turn into calcium hydroxide, thereby helping to keep the air inside the box dry. The gauze is breathable, can wrap the quicklime to prevent it from leaking, and will not block the quicklime from absorbing moisture through the moisture-absorbing material.

[0017] In summary, this utility model has the following beneficial effects:

[0018] This invention features a mesh screen inside the junction box, with a cloth bag containing moisture-absorbing material placed inside the mesh screen. When moisture appears inside the box, the moisture-absorbing material can absorb the moisture through the cloth bag and mesh screen, thus ensuring the dryness of the box interior and achieving a moisture-proof function. Furthermore, by utilizing the flexibility of the silicone sleeve, after a wire passes through it, the inner wall of the silicone sleeve can tightly adhere to the surface of the wire, achieving a waterproof seal. Combined with lubricating oil coating the surface of the wire and filling the inside of the silicone sleeve to form a secondary seal, the waterproof effect of the junction box is further enhanced.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A moisture-proof junction box for a water pump includes a box body 1. Two placement nets 2 are fixedly connected to the bottom of the inner cavity of the box body 1. The placement nets 2 have cloth bags 3 inside, and the cloth bags 3 are filled with moisture-absorbing material 4. External connecting pipes 5 are connected to both sides of the box body 1. The external connecting pipes 5 have internal connecting parts 6 that are threaded to the box body 1. The internal connecting parts 6 have silicone sleeves 7 fixedly connected inside, and the silicone sleeves 7 have lubricating oil 8 inside. By setting the placement nets 2 inside the box body 1 and placing the cloth bags 3 filled with moisture-absorbing material 4 inside the placement nets 2, when moisture appears inside the box body 1, the moisture-absorbing material 4 can absorb the moisture through the cloth bags 3 and placement nets 2, thereby ensuring the dryness of the inside of the box body 1 and realizing the moisture-proof function of the inside of the box body 1. By utilizing the toughness of the silicone sleeve 7, after the wire 10 passes through the silicone sleeve 7, the inner wall of the silicone sleeve 7 can fit tightly with the surface of the wire 10, thereby achieving a seal and waterproofing. Combined with the lubricating oil 8 wrapping the surface of the wire 10 and filling the inside of the silicone sleeve 7 to form a secondary seal, the waterproofing effect of the junction box can be enhanced a second time.

[0027] A circuit board 9 is also installed at the bottom of the inner cavity of the box 1. Both sides of the circuit board 9 are electrically connected to wires 10. The wires 10 are used to connect with the water pump and transmit signals to the water pump, thus realizing the signal transmission function.

[0028] Lubricating oil 8 is wrapped around the surface of the wire 10 and filled inside the silicone sleeve 7. The lubricating oil 8 is used to lubricate the wire 10 and also to seal the surface of the wire 10 and the silicone sleeve 7.

[0029] The surface of the wire 10 is also in sealed contact with the inner wall of the silicone sleeve 7. The silicone sleeve 7 is flexible, and the inner diameter of the end of the silicone sleeve 7 facing the inner wall of the box 1 is smaller than the diameter of the wire 10. By passing the wire 10 through the inner wall of the lubricating oil 8, the silicone sleeve 7 can be forcibly squeezed. The wire 10 can pass through the inside of the silicone sleeve 7, and the inner wall of the end of the silicone sleeve 7 near the inside of the box 1 will be tightly attached to the surface of the wire 10 to form a seal.

[0030] The top of the box body 1 is provided with a box cover 11. The box cover 11 is internally threaded with a fixing screw 12 that is threadedly connected to the box body 1. The box cover 11 is used to close the top of the box body 1, and the fixing screw 12 is used to fix the box body 1 and the box cover 11 together.

[0031] The moisture-absorbing material 4 is specifically quicklime. Quicklime has a strong ability to absorb water and moisture, and can effectively remove moisture. After absorbing moisture from the air, quicklime will turn into calcium hydroxide, thereby helping to keep the air inside the box 1 dry. The gauze is breathable and can wrap the quicklime to prevent it from leaking out, and will not block the quicklime from absorbing moisture through the moisture-absorbing material 4.

[0032] Brief description of usage: When using the device, if moisture is generated inside box 1;

[0033] The moisture-absorbing material 4 can absorb the moisture generated inside the box 1 through the gauze bag 3 and the perforated net 2. After absorbing the moisture, the moisture-absorbing material 4 will also generate heat, increasing the temperature inside the box 1 and thus reducing the humidity inside the box 1.

[0034] During installation, the wire 10 is inserted into the silicone sleeve 7. Since the inner diameter of the silicone sleeve 7 facing the inside of the box 1 is smaller than that of the wire 10, and the silicone sleeve 7 is flexible, when the wire 10 passes through the silicone sleeve 7, pulling the end of the wire 10 facing the inside of the box 1 can force one end of the wire 10 out of the silicone sleeve 7. However, during this process, the wire 10 will compress the silicone sleeve 7 and then spring back. After the silicone sleeve 7 springs back, its inner wall can fit tightly against the surface of the wire 10, thereby forming a seal.

[0035] After the wire 10 and the circuit board 9 are installed and connected, lubricating oil 8 is filled into the inside of the silicone sleeve 7 facing outward. The lubricating oil 8 can coat the surface of the wire 10 and fill the inside of the silicone sleeve 7, thereby forming an oil film. This oil film also has a waterproof function, which can prevent water from entering the inside of the box 1 through the space between the wire 10 and the silicone sleeve 7 when the junction box is used in water.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
