Description

Technical Field

[0001] The utility model relates to the technical field of hair removal devices, and particularly relates to a hair removal device. Background Art

[0002] With the development of modern society, people's living standards have been continuously improved, and people's demands for beauty products have become increasingly rich. As a new type of beauty product, hair removal devices have a broad market prospect. Currently, most hair removal devices on the market use laser technology for hair removal, that is, the hair removal device generates laser through a light source and irradiates it on the human skin. Melanocytes in the hair follicles will absorb the laser, increasing the temperature of the hair follicles, and then destroying the hair follicles to achieve the effect of hair removal. Since a large amount of heat is generated during the laser irradiation process, existing hair removal devices will dissipate the heat in a timely manner by adding a heat dissipation mechanism inside to avoid burning the user's skin due to excessive heat and leaving a bad experience for consumers.

[0003] As disclosed in a hair removal device of Chinese Patent CN217406918U, it specifically discloses a method of dissipating heat inside the hair removal device through the combined action of a main heat dissipation component and an auxiliary heat dissipation component to improve the user experience. Although this method can achieve the cooling effect inside the hair removal device, there are still certain problems. For example, through this heat dissipation method, the heat can only be discharged to the outside of the hair removal device through one channel, that is, the main heat dissipation component. That is, only a single heat dissipation outlet is used for heat dissipation, and it is easy to occur that the heat cannot be discharged to the outside in a timely and effective manner, that is, the heat dissipation efficiency is relatively slow.

[0033] Reference Figure 1 and 2 , in a preferred embodiment, the heat dissipation device includes a mounting shell 2 and a fan 23 located inside the mounting shell 2. The air inlet 201 and the air outlet are both provided on the mounting shell 2. The air outlet includes a first air outlet 202 and a second air outlet 203.

[0034] In this embodiment, with the rotation of the fan 23, part of the heat generated during the operation of the instrument can be discharged to the outside through the first air outlet 202 and the first heat dissipation hole 11; while the other part of the heat is discharged to the outside through the second air outlet 203 and the second heat dissipation hole 12.

[0038] Reference Figure 3 and 4 , in a preferred embodiment, a plurality of heat dissipation fins 420 are provided on the heat dissipation member 42. The plurality of heat dissipation fins 420 are arranged at intervals. An air duct 421 is formed between two adjacent heat dissipation fins 420. The first air outlet 202, the air duct 421 and the first heat dissipation hole 11 are sequentially communicated to form a second heat dissipation channel.

[0039] A plurality of air ducts 421 are formed between the heat dissipation fins 420 arranged at intervals. On the one hand, the air duct 421 can play a role in guiding the flow. At the same time, under the action of the plurality of air ducts 421, the hot air discharged from the first air outlet 202 can be quickly and evenly discharged to the outside. In this embodiment, a part of the hot air coming out of the first air outlet 202 will first flow through the air duct 421 to the first heat dissipation hole 11 (that is, through the second heat dissipation channel), and finally be discharged outside the instrument.

[0040] Reference Figure 3 and 4 , in a preferred embodiment, the heat dissipation support 40 includes a bottom plate 402, a partition plate 403, a baffle plate 404, a first side plate 405 and a second side plate 406. The bottom plate 402, the partition plate 403, the baffle plate 404, the first side plate 405 and the second side plate 406 enclose to form a receiving cavity 401. A first opening 407 is provided on the first side plate 405. A second opening 408 is formed by the interval between the baffle plate 404 and the second side plate 406. One end of the air duct 421 is communicated with the first heat dissipation hole 11 through the first opening 407, and the other end is communicated with the first air outlet 202 through the second opening 408.

[0041] Reference Figure 3, part of the heat sink 420 is covered by the baffle 404. The air from the first air outlet 202 enters the air duct 421 through the second opening 408. Under the partial shielding of the baffle 404, the heat can be discharged to the outside along the path of the second heat dissipation channel. Specifically, the heat dissipation path of the second heat dissipation channel is as follows: The hot air coming out of the first air outlet 202 enters the air duct 421 through the second opening 408. Under the action of the wind direction, the hot air in the air duct 421 flows through the first opening 407 to the first heat dissipation hole 11 and is thus discharged to the outside.

[0042] Reference Figure 1-4 and Figure 7 , in the preferred embodiment, the heat dissipation support 40 further includes a connecting plate 411. The connecting plate 411 and the second side plate 406 are connected to form a communication channel 410. Part of the first air outlet 202 is communicated with the first heat dissipation hole 11 through the communication channel 410; a third opening 409 communicated with the communication channel 410 is further opened on the first side plate 405. The first air outlet 202, the communication channel 410, the third opening 409 and the first heat dissipation hole 11 are sequentially communicated to form a third heat dissipation channel; the partition plate 403 separates the second heat dissipation channel and the third heat dissipation channel.

[0043] Reference Figure 1-4 and Figure 7 , part of the hot air from the first air outlet 202 is discharged to the outside through the second heat dissipation channel, while the other part is discharged through the third heat dissipation channel. The heat dissipation path of the third heat dissipation channel is as follows: The hot air coming out of the first air outlet 202 first flows into the communication channel 410 and then is discharged to the outside through the third opening 409. And the two heat dissipation channels are separated by the partition plate 403, so the hot air in the second heat dissipation channel and the third heat dissipation channel do not communicate with each other and will not affect each other, which further improves the heat dissipation efficiency.

[0044] Reference Figure 6, in a preferred embodiment, the hair removal mechanism includes a light source member 3, the light source member 3 is connected to a heat dissipation part 4, the light source member 3 includes a filter 30, a lamp tube 31 and a reflector 32. Both ends of the reflector 32 are connected to the filter 30 to form a cavity 33, and the lamp tube 31 is located inside the cavity 33; the cavity 33 is part of the third heat dissipation channel. The light emitted by the lamp tube 31 is reflected by the reflector 32 to the filter 30, and then the filter 30 filters light of different wavelengths, and finally the required light is retained to irradiate the human skin, so as to achieve a better hair removal effect. The working principle of the light source member 3 is a known technology in the art and will not be elaborated here. In this embodiment, as part of the third heat dissipation channel, when the wind passes through the cavity 33, it can take away part of the heat generated by the light emission of the light source member 3 inside the cavity 33, that is, it simultaneously realizes the effect of dissipating the heat generated by the light emission of the light source member 3. The hot air at the first air outlet 202 is dissipated through the structure setting of this dual-channel, which can achieve a better heat dissipation effect and also realizes the purpose of rapid heat dissipation.

[0045] Reference Figure 1 , in a further preferred embodiment, a fixing plate 5 is further provided inside the housing 1.

Both the thermoelectric cooler 13 and the transparent crystal 14 are located inside the housing 1, and the thermoelectric cooler 13 and the transparent crystal 14 are connected to the front end of the light source member 3 (here, the front end refers to the end close to the filter 30, and the end close to the reflector 32 is the rear end). The thermoelectric cooler 13, the transparent crystal 14, the light source member 3 and the heat dissipation device are structurally compact inside the entire hair removal device housing 1, making the hair removal device as a whole have the advantages of being small and portable.

[0049] The hair removal instrument provided by the present utility model has the following beneficial effects: Through the setting of double air outlets and double heat dissipation holes, the heat generated when the hair removal instrument works can be discharged to the outside through different air outlets and heat dissipation holes respectively, and the heat dissipation is faster; in addition, the hot air from the first air outlet 202 is dissipated through two independent heat dissipation channels (i.e., the second heat dissipation channel and the third heat dissipation channel), further improving the heat dissipation efficiency; and the whole hair removal instrument has three heat dissipation channels (refer to Figure 7 ), achieving the purpose of rapid heat dissipation and making the user experience better.
