Description

Technical Field

[0001] This utility model relates to the field of hair removal device technology, specifically a waterproof hair removal device. Background Technology

[0002] With the advancement of dermatological research and optical technology, people began to explore the possibility of using optical principles for hair removal. The emergence of laser hair removal technology laid the theoretical foundation for the development of hair removal devices.

[0003] Existing hair removal devices typically involve slowly moving the device along the area to be treated, ensuring each area receives even light exposure and utilizing photothermal principles to remove hair. However, after hair removal, some hair may remain on the device's surface, and the surface can become dirty over time. Therefore, cleaning the device is necessary to improve the user experience.

[0004] However, because hair removal devices generate a lot of heat during use, most have multiple ventilation holes on their surface for heat dissipation. These ventilation holes connect to the inside of the device. Therefore, when cleaning the device, water may enter through these ventilation holes and come into contact with the electronic components, potentially damaging them and affecting the device's usability. To address this, we propose a waterproof hair removal device to effectively solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof hair removal device to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a waterproof hair removal device, comprising a body, on which a first heat dissipation plate is fixedly mounted. The first heat dissipation plate has several groups of first heat dissipation areas arranged in a circle. A second heat dissipation plate is rotatably connected to the side of the first heat dissipation plate facing the outside of the body. The second heat dissipation plate has several groups of second heat dissipation areas arranged in a circle. The number and distribution position of the first heat dissipation areas and the second heat dissipation areas are the same. Several circumferentially arranged sealing blocks are fixedly mounted on the side of the first heat dissipation plate facing the second heat dissipation plate. Several sealing blocks and several first heat dissipation areas are staggered. The number of sealing blocks is equal to the number of second heat dissipation areas. When the second heat dissipation area is rotated to a position directly opposite the sealing block, the second heat dissipation area and the first heat dissipation area are staggered.

[0007] Optionally, the side wall of the housing is provided with a mounting groove for the first heat sink and the second heat sink to be embedded. The first heat sink is fixedly connected to the inner side wall of the mounting groove, and the second heat sink is rotatably connected to the inner side wall of the mounting groove. A plurality of spring balls are arranged circumferentially on the side of the inner side wall of the mounting groove. A plurality of limiting grooves for the spring balls to be embedded are provided on the inner side wall of the mounting groove, and the number of limiting grooves is twice the number of spring balls.

[0008] Optionally, a knob is fixedly provided on the side of the second heat sink facing the outside of the body, and the knob protrudes to the outside of the body.

[0009] Optionally, a connector is fixedly provided on the side of the second heat sink facing the first heat sink, and a connecting groove is provided on the side of the first heat sink facing the second heat sink for the connector to rotate and connect.

[0010] Optionally, a sealing ring is fixedly provided on the inner wall of the connecting groove. Both the sealing ring and the second heat sink are annular. The outer ring surface of the sealing ring is fixedly connected to the inner wall of the connecting groove, and the inner ring surface of the sealing ring and the outer ring surface of the second heat sink are sealed together.

[0011] Compared with the prior art, this utility model provides a waterproof hair removal device, which has the following beneficial effects:

[0012] This invention features a rotatable second heat dissipation plate located outside the first heat dissipation plate. By rotating the second heat dissipation plate, the heat dissipation areas on the two heat dissipation plates can be distributed in two ways: staggered and aligned. When staggered, the sealing block blocks the heat dissipation holes of the second heat dissipation plate, preventing water from entering the hair removal device and giving it a waterproof function.

[0020] 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 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 6 A waterproof hair removal device includes a body 1. A first heat dissipation plate 2 is fixedly mounted on the body 1. The first heat dissipation plate 2 has several groups of first heat dissipation areas 201 arranged in a circle. A second heat dissipation plate 3 is rotatably connected to the side of the first heat dissipation plate 2 facing the outside of the body 1. The second heat dissipation plate 3 has several groups of second heat dissipation areas 301 arranged in a circle. The number and distribution of the first heat dissipation areas 201 and the second heat dissipation areas 301 are consistent to ensure that the first heat dissipation areas 201 and the second heat dissipation areas 301 can dissipate heat when the body 1 is running.

[0022] A plurality of circumferentially arranged sealing blocks 4 are fixedly provided on the side of the first heat dissipation plate 2 facing the second heat dissipation plate 3. The plurality of sealing blocks 4 and the plurality of first heat dissipation areas 201 are staggered. The number of sealing blocks 4 is equal to the number of second heat dissipation areas 301. When the second heat dissipation area 301 is rotated to the position directly opposite the sealing block 4, the second heat dissipation area 301 and the first heat dissipation area 201 are staggered, and the size of the sealing block 4 is larger than the size of the second heat dissipation area 301. So that when the machine body 1 needs to be cleaned, the second heat dissipation plate 3 can be rotated to the state where the second heat dissipation area 301 and the first heat dissipation area 201 are staggered. At this time, the second heat dissipation area 301 of the sealing block 4 will move to the position directly opposite the sealing block 4. Since the size of the sealing block 4 is larger than the size of the second heat dissipation area 301, the sealing block 4 can completely seal the second heat dissipation area 301, thereby preventing water from entering the first heat dissipation plate 2 from the second heat dissipation area 301, that is, preventing water from entering the interior of the machine body 1, and avoiding affecting the use of the machine body 1.

[0023] To ensure the second heat sink 3 can be fixed when rotated to the appropriate position, this application provides a mounting groove 101 on the side wall of the body 1 for the first heat sink 2 and the second heat sink 3 to be inserted. The first heat sink 2 is fixedly connected to the inner side wall of the mounting groove 101, and the second heat sink 3 is rotatably connected to the inner side wall of the mounting groove 101. Several spring-loaded balls 302 are arranged circumferentially on the side of the inner side wall of the mounting groove 101 on the second heat sink 3. Several spring-loaded balls 302 are provided on the inner side wall of the mounting groove 101. The spring ball 302 is embedded in the limiting groove 102, and the number of limiting grooves 102 is twice the number of spring balls 302, so that when the second heat dissipation plate 3 rotates to align with the second heat dissipation area 301 and the first heat dissipation area 201, it can be positioned by the spring ball 302 and the limiting groove 102, so that the heat inside the body 1 can be dissipated; when the second heat dissipation plate 3 rotates to align with the second heat dissipation area 301 and the sealing block 4, it can also be positioned, so that the body 1 has a waterproof function.

[0024] To make the rotation of the second heat sink 3 more convenient, this application provides a knob 303 on the side of the second heat sink 3 facing the outside of the body 1. The knob 303 protrudes to the outside of the body 1 so that the user can more conveniently control the rotation of the second heat sink 3.

[0025] Furthermore, a connector 304 is fixedly provided on the side of the second heat sink 3 facing the first heat sink 2, and a connecting groove 202 is provided on the side of the first heat sink 2 facing the second heat sink 3 for the connector 304 to rotate and connect, so that the second heat sink 3 will not detach from the first heat sink 2 when rotating, thus avoiding affecting the waterproof effect.

[0026] In this embodiment, a sealing ring 203 is fixedly provided on the inner sidewall of the connecting groove 202. Both the sealing ring 203 and the second heat sink 3 are annular. The outer ring surface of the sealing ring 203 is fixedly connected to the inner sidewall of the connecting groove 202. The inner ring surface of the sealing ring 203 and the outer ring surface of the second heat sink 3 are sealed together, so that after water enters between the first heat sink 2 and the second heat sink 3 from the connection between the second heat sink 3 and the mounting groove 101, it will be blocked by the sealing ring 203, preventing water from reaching the position of the first heat dissipation area 201, thus improving the waterproof effect of the body 1.

[0027] The working principle and usage process of this utility model are as follows: First, when using the hair removal device normally, rotate the second heat dissipation plate 3 at a certain angle so that the second heat dissipation area 301 and the first heat dissipation area 201 are aligned. At this time, the heat generated inside the device 1 can be dissipated to the outside of the device 1. When it is necessary to clean the device 1, rotate the second heat dissipation plate 3 at a certain angle so that the second heat dissipation area 301 and the first heat dissipation area 201 are misaligned, and align the second heat dissipation area 301 with the sealing block 4. At this time, the second heat dissipation area 301 is sealed, and the device 1 can be cleaned with water.
