Description

Technical Field

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

[0002] With the popularization of social media, people's pursuit of "flawless skin" has become stronger and stronger, and hair removal has become an important part of improving personal image. Because it can be applied to multiple parts of the body, such as legs, underarms, face, and back, it meets the diverse needs of different users. It does not require an appointment with a professional beauty institution or hospital, saving time and energy, and is therefore widely used.

[0003] During use, lasers or intense pulsed light emit high-energy beams, generating a large amount of heat inside the device. Therefore, a heat dissipation structure is needed to cool it down and prevent irreversible damage to the internal components. To dissipate heat, it is difficult to avoid opening small holes in the device for heat dissipation. However, with prolonged use, dust can enter the device through these small holes and accumulate, seriously affecting the lifespan of the internal components. Existing heat dissipation structures for hair removal devices often have dedicated ventilation channels at the air outlet. These channels only allow air to flow in a preset direction, thus avoiding backflow problems. However, this also causes the airflow to move in the opposite direction to clean the inside of the device.

[0004] Therefore, a heat dissipation structure for hair removal devices is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a heat dissipation structure for hair removal devices, which has advantages such as self-cleaning and long service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution: It includes an outer shell, inside which a protective shell is provided. Two or more motors are fixedly mounted on both the upper and lower surfaces of the protective shell, with one end open. Holes 1 and 2 are respectively opened on the two sides near the opposite end. A groove is opened at corresponding positions on both the upper and lower surfaces inside the protective shell. A gear is installed inside the groove. The output end of the motor is rotatably connected to the gear. A soft band is fitted over the outer surface of the gear, and the middle of the soft band is hollowed out. The protective shell is provided with a Tesla valve-shaped exhaust plate, and the exhaust plate located in the middle is disposed inside the flexible strip.

[0007] Preferably, a sealing cover is provided on the outer side of the protective shell, and the sealing cover is fixedly installed on the inner surface of the outer shell. A sealed space is formed between the sealing cover, the inner surface of the outer shell, and the protective shell. An exhaust filter screen is provided on the side of the outer shell in the sealed space.

[0008] Preferably, the upper inner surface of the protective shell has a groove two at the opening, a threaded rod is provided inside the groove two, a motor two is fixedly provided on one outer surface of the protective shell, the output end of the motor two is rotatably connected to the threaded rod, and a sliding plate is sleeved on the outer surface of the threaded rod.

[0009] Preferably, a heat-conducting plate and a bidirectional fan are fixedly installed inside the outer shell, and the two ends of the heat-conducting plate are fixedly connected to the bidirectional fan and the opening end of the protective shell, respectively.

[0010] Preferably, the length of the hollowed-out section in the middle of the soft strip is half of its total length, and the height of the hollowed-out section of the soft strip and the height of the exhaust plate are consistent with the internal height of the protective shell.

[0011] Preferably, an air intake filter is provided on one side surface of the housing, and the air intake filter and the exhaust filter are not on the same plane.

[0017] 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. Example

[0018] Please see Figure 1 - Figure 7 The heat dissipation structure for a hair removal device in this embodiment includes a housing 14, a protective shell 15 inside the housing 14, two or more motors 9 fixedly mounted on the upper and lower surfaces of the protective shell 15 with one end open, and holes 18 and 19 respectively opened on the two sides near the opposite end. Grooves 8 are opened at corresponding positions on the upper and lower surfaces inside the protective shell 15, and gears 6 are installed inside the grooves 8. The output end of the motor 9 is rotatably connected to the gear 6. A soft band 10 is sleeved on the outer surface of the gear 6, and the soft band 10 is hollowed out in the middle. The protective shell 15 is provided with a Tesla valve-shaped exhaust plate 7, and the exhaust plate 7 located in the middle is located inside the flexible strip 10. Among them, motor 9 is electrically connected to the control equipment outside the protective shell 15. Under normal working conditions, the heat energy of the hair removal device is discharged to the exhaust filter 5 through hole 19 inside the protective shell 15. After a certain period of use, the electric gear 6 of motor 9 and the soft belt 10 on its outer surface rotate simultaneously. When the soft belt 10 rotates to the side where hole 19 is located, the fan rotates in the opposite direction, drawing external air into the device through hole 18 and discharging it. This cleans the inside of the heat dissipation mechanism and the air inlet, completing self-cleaning, improving the cleanliness of the device, avoiding dust accumulation, and extending the overall service life of the device.

[0019] A sealing cover 4 is provided on the outside of the protective shell 15. The sealing cover 4 is fixedly installed on the inner surface of the outer shell 14. A sealed space is formed between the sealing cover 4, the inner surface of the outer shell 14, and the protective shell 15. An exhaust filter 5 is provided on the side of the outer shell 14 in the sealed space. Among them, the sealed space formed between the sealing cover 4, the inner surface of the outer shell 14, and the protective shell 15 allows air to circulate only in two places: the exhaust filter 5 and the air exchange port of the protective shell 15. This enables precise control of the internal airflow, allowing the airflow to be more concentrated and directed to the key areas that need cooling, thereby enhancing the heat dissipation effect.

[0020] The upper inner surface of the protective shell 15 has a groove 12 at the opening, and a threaded rod 13 is provided inside the groove 12. A motor 16 is fixedly provided on one side of the outer surface of the protective shell 15. The output end of the motor 16 is rotatably connected to the threaded rod 13. A sliding plate 11 is fitted on the outer surface of the threaded rod 13. The width of the slide plate 11 is not less than half the width of the opening of the protective shell 15. The motor 16 is electrically connected to the control device outside the protective shell 15. When the airflow direction changes, the motor 16 drives the threaded rod 13, so that the slide plate 11 can move linearly inside the slot 12, thereby closing the other entrance and exit in the direction required by the airflow, avoiding airflow diversion, reducing the speed and affecting the heat dissipation effect.

[0021] A heat-conducting plate 2 and a bidirectional fan 3 are fixedly installed inside the outer shell 14. The two ends of the heat-conducting plate 2 are fixedly connected to the bidirectional fan 3 and the opening end of the protective shell 15, respectively. The heat-conducting plate 2, the bidirectional fan 3, and the protective shell 15 are all tightly connected, forming an effective airflow channel. This allows the cooling air to come into more direct contact with the surface of the heat-conducting plate 2, thereby enhancing the heat exchange effect and improving the heat dissipation efficiency.

[0022] The length of the hollowed-out part in the middle of the soft strip 10 is half of its total length, and the height of the hollowed-out part of the soft strip 10 and the height of the exhaust plate 7 are consistent with the internal height of the protective shell 15. The upper and lower surfaces of the hollowed-out part of the soft strip 10 are flush with the upper and lower surfaces of the inner part of the protective shell 15, so that the airflow will not be blocked by obstacles when passing through the inside of the protective shell, thereby reducing the wind speed and affecting the heat dissipation and dust removal effect.

[0023] An intake filter 1 is provided on one side surface of the outer casing 14. The intake filter 1 and the exhaust filter 5 are not on the same plane. The intake filter 1 and the exhaust filter 5 are located on two different surfaces of the housing 14, thereby reducing the chance of the incoming air mixing with the outgoing air, preventing the so-called "airflow short circuit", ensuring that the air entering the equipment is as uncontaminated as possible, enhancing the heat dissipation effect and improving the cleanliness of the equipment's interior.

[0024] The inner surface of the protective shell 15 at the end opposite the opening and the sliding plate 11 are in contact with the soft strip 10. The longer partition of the exhaust plate 7 is tightly fitted to the inner wall of the protective shell 15, while the shorter partition of the exhaust plate 7 does not contact the inner wall of the protective shell 15. Among them, the skateboard 11 and the soft belt 10 can effectively isolate the airflow inside the protective shell 15 that is not blocked by the skateboard 11, which helps to maintain a stable airflow and reduce noise caused by airflow turbulence.

[0025] The working principle of the above embodiments is as follows: During use, motor 9 and motor 16 are electrically connected to the control equipment outside the protective shell 15. Under normal working conditions, the heat energy of the hair removal device is discharged through the protective shell 15 through hole 19 to the exhaust filter 5. After a certain period of use, the electric gear 6 of motor 9 and the soft belt 10 on its outer surface rotate simultaneously. When the soft belt 10 rotates to the side where hole 19 is located, motor 16 drives the slide plate 11 to move and change the air duct. The fan rotates in the opposite direction, drawing external air into the device through hole 18 and discharging it. This cleans the inside of the heat dissipation mechanism and the air inlet, completing self-cleaning, improving the cleanliness of the device, avoiding dust accumulation, and extending the overall service life of the device.

[0026] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0027] 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.
