Description

Technical Field

[0001] This utility model relates to the field of waterproof motor technology, specifically a motor with waterproof function. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is represented by the letter M in circuit diagrams. Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines.

[0003] Traditional motors are often used in relatively dry environments, so they generally do not have waterproofing capabilities. Once water gets inside the motor, it will corrode the internal circuitry, causing damage to the internal circuitry, resulting in a short circuit and preventing the motor from operating normally. This affects the normal use of the motor and causes a certain degree of economic loss. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a waterproof motor that offers advantages such as good waterproof performance and ease of use, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a waterproof motor, comprising a motor body, a drive shaft mounted on the outer wall of the motor body, a junction box mounted on the top of the motor body, a terminal block fixedly fitted inside the junction box, a top cover mounted on the top of the junction box, a conduit fixedly fitted on the top of the top cover, a movable plug fixedly fitted on the bottom of the top cover, a sealing plate mounted on the outer wall of the motor body, a rotating plate fixedly fitted on the outer wall of the drive shaft, a fixing ring fixedly fitted inside the sealing plate, a sealing ring installed inside the sealing plate, a sponge absorbent plate installed inside the sealing plate, and a sealing plate mounted on the outer wall of the sealing plate.

[0006] As a preferred technical solution of this utility model: the outer wall shape of the movable plug matches the inner wall shape and size of the junction box, and a rubber sealing gasket is installed on the outer wall of the movable plug.

[0007] As a preferred technical solution of this utility model: the conduit is made of natural rubber, and the installation position of the conduit corresponds to the installation position of the terminal block.

[0008] As a preferred technical solution of this utility model: the inner cavity of the sealing plate is provided with a rotating groove, and the inner wall shape of the rotating groove matches the outer wall shape and size of the rotating plate.

[0009] As a preferred technical solution of this utility model: the outer wall shape of the sponge absorbent plate matches the outer wall shape of the sealing plate, and the sealing plate is installed on the outer wall of the sealing plate by fixing screws.

[0010] As a preferred technical solution of this utility model: there are two sponge water-absorbing plates, and the two sponge water-absorbing plates are respectively installed in the inner cavities on the upper and lower sides of the sealing plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This waterproof motor uses a top cover on the top of the junction box and a movable plug on the outer wall of the top cover. When the top cover is installed on the top of the terminal block, the movable plug will seal the top of the junction box, thereby achieving a seal. The wires are then passed through the conduit on the top of the top cover into the inner cavity of the junction box, connecting the wires to the terminal block. The conduit further ensures the seal inside the junction box.

[0013] 2. This waterproof motor uses a sealing plate on the outer wall of the motor body to seal the drive shaft and the motor body. When the drive shaft rotates, the inner wall of the sealing plate and the outer wall of the rotating plate act as a barrier against water. The water entering the inner cavity of the sealing plate is absorbed by the sponge absorbent plate in the inner cavity of the rotating plate, thus achieving a better sealing effect on the motor body.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 A waterproof motor includes a motor body 1, a drive shaft 2 mounted on the outer wall of the motor body 1, a junction box 3 mounted on the top of the motor body 1, a terminal block 4 fixedly mounted in the inner cavity of the junction box 3, a top cover 5 mounted on the top of the junction box 3, a conduit 6 fixedly mounted on the top of the top cover 5, a movable plug 7 fixedly mounted on the bottom of the top cover 5, a sealing plate 8 mounted on the outer wall of the motor body 1, a rotating plate 9 fixedly mounted on the outer wall of the drive shaft 2, a fixing ring 10 fixedly mounted in the inner cavity of the sealing plate 8, a sealing ring 11 mounted in the inner cavity of the sealing plate 8, a sponge absorbent plate 12 mounted in the inner cavity of the sealing plate 8, and a sealing plate 13 mounted on the outer wall of the sealing plate 8.

[0022] In the above structure, by using the top cover 5 provided on the top of the junction box 3 and the movable plug 7 provided on the outer wall of the top cover 5, when the top cover 5 is installed on the top of the junction box 3, the outer wall of the movable plug 7 will enter the inner cavity of the junction box 3, thereby sealing the top of the junction box 3, thus achieving a better waterproof effect and preventing water from entering the inner cavity of the junction box 3.

[0023] In a preferred embodiment, the outer wall shape of the movable plug 7 matches the inner wall shape and size of the junction box 3, and a rubber sealing gasket is installed on the outer wall of the movable plug 7.

[0024] In the above structure, the movable plug 7 installed on the outer wall of the top cover 5 seals the top of the junction box 3 when the top cover 5 is installed on the top of the junction box 3. The outer wall of the movable plug 7 is equipped with a rubber sealing gasket, which further enhances the sealing effect on the top of the junction box 3.

[0025] In a preferred embodiment, the conduit 6 is made of natural rubber, and the installation position of the conduit 6 corresponds to the installation position of the terminal block 4.

[0026] In the above structure, by installing a conduit 6 on the top of the top cover 5, when it is necessary to connect the wire to the terminal 4, the wire is inserted from the inner cavity of the conduit 6 into the inner cavity of the junction box 3. The inner wall of the conduit 6 will be tightly connected to the outer wall of the wire, thereby achieving a good sealing effect and preventing water from entering the inner cavity of the junction box 3 through the conduit 6.

[0027] In a preferred embodiment, the inner cavity of the sealing plate 8 is provided with a rotating groove, and the inner wall shape of the rotating groove matches the outer wall shape and size of the rotating plate 9.

[0028] In the above structure, through the rotating groove opened in the inner cavity of the sealing plate 8 and the rotating plate 9 set on the outer wall of the drive shaft 2, the rotating plate 9 will rotate in the inner cavity of the sealing plate 8 during the rotation of the drive shaft 2. At this time, if the external water wants to pass through the sealing plate 8 and enter the inner cavity of the motor body 1, it needs to pass through the rotating plate 9 and the sealing plate 8 before entering the inner cavity of the motor body 1.

[0029] In a preferred embodiment, the outer wall shape of the sponge absorbent plate 12 matches the outer wall shape of the sealing plate 13, and the sealing plate 13 is installed on the outer wall of the sealing plate 8 by fixing screws.

[0030] In the above structure, the sponge absorbent plate 12 installed in the inner cavity of the sealing plate 8 can absorb the water that has penetrated into the inner cavity of the sealing plate 8, thereby preventing water from passing through the inner cavity of the sealing plate 8. The waterproof effect is further improved by the action of the rotating plate 9 and the inner wall of the sealing plate 8.

[0031] In a preferred embodiment, there are two sponge absorbent plates 12, and the two sponge absorbent plates 12 are respectively installed in the inner cavities on the upper and lower sides of the sealing plate 8.

[0032] In the above structure, the sponge absorbent plates 12 installed in the inner cavities on the upper and lower sides of the sealing plate 8 allow external water to enter the inner cavity of the sealing plate 8 through the gap between the rotating plate 9 and the inner wall of the sealing plate 8. The water is then absorbed by the sponge absorbent plates 12. The sealing ring 11 in the inner cavity of the sealing plate 8 can be replaced by removing the sealing plate 13 from the outer wall of the sealing plate 8.

[0033] Working Principle: During use, the device utilizes a top cover 5 installed on the top of the junction box 3 and a movable plug 7 on its outer wall. When the top cover 5 is installed on the outer wall of the junction box 3, the outer wall of the movable plug 7 enters the inner cavity of the junction box 3, sealing the top of the junction box 3 and improving the sealing effect within the junction box 3. When connecting the wire to the terminal 4, the wire passes through the inner cavity of the conduit 6, causing the inner wall of the conduit 6 to fit against the outer wall of the wire, thereby... To achieve a better sealing effect, a sealing plate 8 is installed on the outer wall of the motor body 1. When the drive shaft 2 rotates, the rotating plate 9 on the outer wall of the drive shaft 2 will rotate in the inner cavity of the sealing plate 8. Under the action of the outer wall of the rotating plate 9 and the inner wall of the sealing plate 8, water that wants to enter the inner cavity of the motor body 1 needs to pass through the outer wall of the rotating plate 9 and the inner wall of the sealing plate 8. Under the action of the sponge water-absorbing plate 12, the water entering the inner cavity of the sealing plate 8 is absorbed, thereby achieving a better sealing effect and ensuring the sealing performance of the motor body 1 during use.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
