DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] refer to Figure 1 and Figure 2 , the present application provides a hair removal device with a heat dissipation mechanism, including a body shell 1, a circuit board 2, a light source module 3 and a heat dissipation module 4;

[0032] The circuit board 2, the light source module 3 and the heat dissipation module 4 are all arranged in the housing 1. A processing unit 5 is set on the circuit board 2. The light source module 3 and the heat dissipation module 4 are fixed on the circuit board 2 and connected to the processing unit 5 through the circuit board 2.

[0033] In addition, a laser opening is provided on the side wall of the body shell 1, and the light source module 3 extends out from the laser opening, thereby realizing the laser irradiation function. A lower air inlet 7 is provided on the bottom plate of the body shell 1 at a position corresponding to the heat dissipation module 4, and a heat sink 6 is provided between the lower air inlet 7 and the heat dissipation module 4. The heat sink 6 covers the light source module 3. When the heat dissipation module 4 is working, air can be inhaled from the lower air inlet 7. An air outlet 8 is also provided on the side wall of the body shell 1 at a position corresponding to the heat dissipation module 4. When the heat dissipation module 4 is working, air can be blown out from the air outlet 8, thereby realizing the function of dissipating the heat on the heat sink 6.

[0034] As described in the above embodiment, a cooling fan is provided in the heat dissipation module 4, and the heat dissipation module 4 is connected to the processing unit 5, so that the cooling fan is started to suck and blow air according to the control signal sent by the processing unit 5, thereby achieving the function of heat dissipation. The light source module 3 is a laser transmitter for laser hair removal, which is used to perform laser irradiation according to the control signal sent by the processing unit 5, thereby achieving the hair removal effect;

[0035] Among them, since the heat sink 6 covers the light source module 3 and the heat dissipation module 4, the heat generated by the light source module 3 when it is close to the user's skin for irradiation can be directly conducted to the heat sink 6, and since the heat sink 6 is arranged between the lower air inlet 7 and the heat dissipation module 4, when the heat dissipation module 4 draws air from the lower air inlet 7, the heat sink 6 can be cooled at the same time, thereby achieving an enhanced heat dissipation effect.

[0036] Through the above structure, this embodiment realizes large-area heat dissipation of the light source module and the heat dissipation module by setting a heat sink covering the light source module and the heat dissipation module, and the heat dissipation module inhales cooling air from the lower air inlet and blows it out from the air outlet, thereby achieving the function of enhancing the heat dissipation effect, solving the problem in the prior art that the light source component of the existing hair removal device will generate a lot of heat during use, and the light source component will directly contact the user's skin, causing the user to easily burn the skin when using laser hair removal, thereby improving the safety of the hair removal device when in use.

[0037] refer to Figure 2 , In one embodiment, a heat dissipation fin 61 is provided below the heat sink 6;

[0038] A cavity 41 is provided in the light source module 3, and the cavity 41 is connected to the air outlet 8. The heat dissipation fins 61 are inserted into the cavity 41, and then the heat dissipation fins 61 are inserted into the light source module 3, so as to achieve the function of conducting the heat generated by the light source module 3 through the heat dissipation fins 61 to the heat sink 6 for dissipation.

[0039] As described in the above embodiment, a heat sink 6 is provided with a heat sink fin 61 under the heat sink 6, and a cavity 41 is provided in the light source module 3. When the heat sink 6 covers the light source module 3 and the heat dissipation module 4, the heat sink fin 61 is inserted into the cavity 41, and since the cavity 41 is connected to the air outlet 8, the function of exporting the heat generated by the light source module 3 and then blowing it out from the air outlet 8 is realized.

[0040] A layer of heat-conducting material is pasted on the inner wall of the cavity 41 , so as to realize the function of increasing the heat-conducting efficiency between the heat sink 6 and the light source module 3 . It can be understood that the heat-conducting material in this embodiment is graphene.

[0041] refer to Figure 1 In one embodiment, a trigger button 11 is further provided on the housing 1, and a button plate 21 is further provided on one side of the circuit board 2;

[0042] The key board 21 is connected to the circuit board 2 , and a key unit 12 is provided on the key board 21 at a position corresponding to the trigger key 11 . When the user presses the trigger key 11 , the trigger key 11 is deformed and presses the key unit 12 , thereby achieving the function of the trigger key unit 12 .

[0043] As described in the above embodiment, a key panel 21 is provided on one side of the circuit board 2. It can be understood that the key panel 21 is used to fix the key unit 12. In addition, a trigger button 11 is also provided on the body shell 1. It can be understood that the trigger button 11 is made of soft rubber material, and the key unit 12 is fixed under the trigger button 11. Therefore, when the user presses the trigger button 11, the trigger button 11 is deformed and presses the key unit 12, thereby achieving the function of the trigger button unit 12.

[0044] refer to Figure 1 and Figure 3 ,In one embodiment, the keypad 21 is connected to a sensing unit 22;

[0045] The sensing unit 22 is fixed in the light source module 3 and transmits an induction current to the light source module 3. When the user's skin contacts the light source module 3, the processing unit 5 determines that the induction current fluctuates, thereby realizing the touch recognition function.

[0046] As described in the above embodiment, the keypad 21 is connected to a sensing unit 22, the sensing unit 22 is clamped in the light source module 3, and the sensing unit 22 is connected to the processing unit 5 through the keypad 21. It can be understood that a contact head made of crystal material is provided at one end of the light source module 3, and two electrodes, one positive and one negative, are provided on the sensing unit 22. Therefore, the sensing unit 22 can continuously output a corresponding induced current to the contact head, so that the contact head can achieve an effect similar to capacitive touch recognition. When the light source module 3 contacts the user's skin, the induced current between the user's skin and the sensing unit 22 fluctuates. At this time, the processing unit 5 recognizes that the light source module 3 contacts the user's skin, thereby realizing the touch recognition function;

[0047] It is understandable that since the light source module 3 consumes large power when irradiating laser, and continuous irradiation of laser can easily cause damage to the user's body due to improper use, in this embodiment, the light source module 3 can only be controlled to perform normal laser irradiation when the processing unit 5 recognizes through the sensing unit 22 that the light source module 3 is close to the user's skin.

[0048] refer to Figure 2 In one embodiment, a switch button 23 is also provided on one side of the circuit board 2;

[0049] The switch button 23 is connected to the circuit board 2. A switch opening is provided on the side wall of the housing 1. When the circuit board 2 is arranged in the housing 1, the switch button 23 extends from the switch opening, thereby realizing the corresponding switch control function.

[0050] As described in the above embodiment, a switch button 23 is provided on one side of the circuit board 2, and the switch button 23 extends from the side wall of the body shell 1. When the user presses the switch button 23, the application can be switched to an on state or an off state. After the application is switched to the on state, the user can control the illumination of the light source module 3 by pressing the trigger button 11.

[0051] refer to Figure 2 , In one embodiment, a relay 24 is also provided on the circuit board 2;

[0052] The input end of the relay 24 is connected to the storage capacitor 25 fixed on the circuit board 2 through the circuit board 2 , and the other end of the relay 24 is connected to the light source module 3 , thereby realizing the function of voltage conversion and power supply for the light source module 3 .

[0053] As described in the above embodiment, a storage capacitor 25 and a relay 24 are provided on the circuit board 2, wherein the input end of the relay 24 is connected to the storage capacitor 25, and the output end of the relay 24 is connected to the light source module 3. It can be understood that the light source module 3 requires a larger voltage for power supply during laser irradiation, so the relay 24 can charge the storage capacitor 25 and then transform the power released by the storage capacitor 25 and input it into the light source module 3, thereby realizing the function of transforming the power supply for the light source module 3.

[0054] refer to Figure 4 In one embodiment, the housing 1 is further provided with a tail end heat dissipation port 13;

[0055] The tail end heat dissipation port 13 is arranged on the opposite side of the body shell 1 to the light source module 3, and the circuit board 2 is provided with a power supply socket 26 connected to the storage capacitor 25. When the circuit board 2 is arranged in the body shell 1, the power supply socket 26 passes through the connection hole set on the tail end heat dissipation port 13, thereby realizing the function of connecting an external charging line and dissipating internal heat at the same time.

[0056] As described in the above embodiment, a tail end heat dissipation port 13 is further provided at the tail end of the body shell 1, a power supply socket 26 connected to the storage capacitor 25 is provided on the circuit board 2, and a charging opening is also provided on the tail end heat dissipation port 13. When the circuit board 2 is arranged in the body shell 1, the power supply socket 26 passes through the connection hole provided on the tail end heat dissipation port 13, thereby realizing the function of connecting an external charging cable for charging.

[0057] From the above embodiments, it can be seen that the greatest beneficial effect of the present application is that by providing a heat sink covering the light source module and the heat dissipation module, and by the heat dissipation module sucking in cooling air from the lower air inlet and blowing it out from the air outlet, a large area of ​​heat dissipation for the light source module and the heat dissipation module is achieved, thereby achieving the function of enhancing the heat dissipation effect, solving the problem in the prior art that the light source component of the existing hair removal device will generate a lot of heat during use, and the light source component will directly contact the user's skin, causing the user to easily burn the skin when using laser hair removal, thereby improving the safety of the hair removal device when in use.

[0058] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
