[0050] With the improvement of people's living standards, hair removal devices have become one of the commonly used electronic devices in people's lives. In the related art, in order to make the shape of the hair removal device more in line with the user's usage habits, the head of the hair removal device is set to be arc-shaped, but the arc-shaped setting will cause insufficient space, resulting in the head shell and the heat dissipation shell inside the hair removal device cannot be fixed by screw connection, reducing the structural stability of the hair removal device.

[0051] The utility model mainly provides a hair removal device, aiming to solve the technical problem of how to improve the structural stability of the hair removal device.

[0052] The specific structure of the hair removal device will be mainly described below.

[0053] like Figures 1 to 7 As shown, Figure 1 This is a schematic structural diagram of an embodiment of the hair removal device of the utility model; Figure 2 This is a structural exploded view of an embodiment of the hair removal device of the utility model; Figure 3 for Figure 2 A partial enlarged view of the middle A; Figure 4This is a structural exploded view of another embodiment of the hair removal device of the utility model; Figure 5 for Figure 4 A partial enlarged view of point B in the middle; Figure 6 It is a cross-sectional schematic diagram of an embodiment of the hair removal device of the utility model; Figure 7 for Figure 6 A partial enlarged view of point C in the middle.

[0054] The hair removal device comprises: a shell 10, the shell 10 comprises a head 11 and a tail 12 connected in the length direction thereof, the head 11 is arranged in an arc shape, and the head 11 and the tail 12 cooperate to form an installation cavity; and a heat dissipation shell 20, the heat dissipation shell 20 is arranged in the installation cavity, and one end of the heat dissipation shell 20 is connected to the shell wall of the tail 12, and the other end of the heat dissipation shell 20 is fixedly connected to the head 11, and the heat dissipation shell 20 is used to carry at least part of the element 40 to be dissipated; wherein, one of the head 11 and the heat dissipation shell 20 is provided with a clamping position 13, and the other is provided with a buckle 21 that is clamped and matched with the clamping position 13, and the heat dissipation shell 20 is clamped with the clamping position 13 through the buckle 21.

[0055] In this embodiment, the form of the shell 10 can be many, for example, it can be formed by splicing two shell parts, or it can be formed by splicing three or more shell parts. Taking the shell 10 including an upper shell 15 and a lower shell 16 as an example, the upper shell 15 and the lower shell 16 are spliced ​​along the width direction of the shell 10 to enclose and form an installation cavity. The width direction of the shell 10 is perpendicular to the length direction. The shell 10 is in the shape of a long strip as a whole, wherein the head 11 is arranged in an arc shape, and the arc-shaped head 11 is more in line with the user's usage habits and can improve the appearance integrity of the hair removal device. The heat dissipation shell 20 is used for installing the heat dissipation element 40, and the heat dissipation element 40 can be a functional element such as a lamp tube or a chip. The heat dissipation shell 20 needs to be fixedly connected to the shell 10 to achieve stable installation in the installation cavity and make the heat dissipation element 40 installed in the heat dissipation shell 20 more stable.

[0056] Taking the example that the clamping position 13 is provided on the head 11 and the buckle 21 is provided on the heat dissipation shell 20, the specific forms of the clamping position 13 and the buckle 21 are not limited, and it is only necessary that the clamping position 13 and the buckle 21 can be clamped and fixed. The clamping position 13 and the buckle 21 are clamped and fixed, which can realize the fixed connection between the head 11 of the housing 10 and the heat dissipation shell 20, and eliminate the need for fasteners, so that the fixing method of the head 11 and the heat dissipation shell 20 can be simplified on the basis of setting the head 11 to be arc-shaped, so as to improve the assembly convenience and assembly stability of the hair removal device.

[0057] Specifically, Figure 5 and Figure 7As shown, the heat dissipation shell 20 is formed with a heat dissipation channel 22, which is used to dissipate heat from the heat dissipation element 40; the outer shell 10 is provided with an air outlet 14, which is connected to the heat dissipation channel 22; the buckle 21 and the clamping position 13 connect part of the side wall of the heat dissipation channel 22 with part of the peripheral wall of the air outlet 14.

[0058] The heat dissipation channel 22 can be used for heat dissipation airflow, and the heat dissipation element 40 can be installed in the heat dissipation channel 22, so that the airflow flowing through the heat dissipation channel 22 can bring the heat of the heat dissipation element 40 to the air outlet 14. The housing 10 is also provided with an air inlet, and the hair removal device can also include an air supply component, which is installed between the air inlet and the heat dissipation channel 22. The air supply component has many forms, such as a fan. The air supply component can drive the external airflow to flow from the air inlet into the heat dissipation channel 22, take away the heat of the heat dissipation element 40, and then flow out of the air outlet 14, so as to achieve heat dissipation of the heat dissipation element 40. The buckle 21 and the latch 13 connect the heat dissipation channel 22 with the air outlet 14. The connection means that one of the buckle 21 and the latch 13 is connected, abutted or close to the end of the heat dissipation channel 22, and the other is connected, abutted or close to the periphery of the air outlet 14. In this way, the buckle 21 and the latch 13 can form an extension of the heat dissipation channel 22, or guide the airflow of the heat dissipation channel 22 to the air outlet 14, so that the heat dissipation airflow can fully flow out of the air outlet 14 after flowing out of the heat dissipation channel 22, thereby preventing the heat dissipation airflow from flowing to other positions of the installation cavity.

[0059] For example, Figure 5 and Figure 7 As shown, the wall of the heat dissipation channel 22 includes a first wall portion 23, one of the buckle 21 and the clamping position 13 is arranged at one end of the first wall portion 23 close to the air outlet 14, and the other is arranged on the peripheral wall of the air outlet 14. In this way, the interference of the buckle 21 and the clamping position 13 with other components in the installation cavity or the heat dissipation shell 20 can be reduced, so as to simplify the clamping process of the buckle 21 and the clamping position 13.

[0060] Specifically, Figure 8 and Fig. 9 As shown, Figure 8 This is a structural exploded view of another embodiment of the hair removal device of the utility model; Fig. 9 for Figure 8 The partial enlarged view of the D in the middle. The buckle 21 is arranged on the first wall portion 23, and the wall surface of the buckle 21 close to the heat dissipation channel 22 is formed as a guide surface 211, and the guide surface 211 and the inner wall surface of the first wall portion 23 together constitute an air guide structure. The guide surface 211 can guide the heat dissipation airflow flowing to the end of the heat dissipation channel 22 to the air outlet 14 more and more fully, thereby further reducing the cross-flow of the heat dissipation airflow to other positions of the installation cavity, so as to further improve the heat dissipation effect of the heat dissipation shell 20.

[0061] For example, Figure 7As shown, the wall of the heat dissipation channel 22 includes a first wall portion 23 and a second wall portion 24 that are arranged opposite to each other, the heat dissipation element 40 is arranged close to the second wall portion 24, or the heat dissipation element 40 is installed on the second wall portion 24, and the buckle 21 or the clamping position 13 is arranged on the first wall portion 23. The heat dissipation element 40 is arranged on the side wall away from the buckle 21, so as to avoid the clamping position 13 and the buckle 21 from squeezing or damaging the heat dissipation element 40, thereby improving the protection effect of the heat dissipation element 40.

[0062] Specifically, Figures 7 to 9 As shown, the housing 10 includes an upper housing 15, a lower housing 16 and a decorative housing 17. The upper housing 15 and the lower housing 16 are spliced ​​along the width direction of the housing 10 to enclose a mounting cavity. The width direction of the housing 10 is perpendicular to the length direction. The decorative housing 17 is covered on the outer side of the lower housing 16. The air outlet 14 is opened in the lower housing 16. The flow cross section of the air outlet 14 is greater than or equal to the flow cross section of the heat dissipation channel 22 to avoid the part of the heat dissipation component 40 extending out of the heat dissipation channel 22. The decorative housing 17 is provided with a plurality of air outlet holes 171, and the plurality of air outlet holes 171 are all connected to the air outlet 14.

[0063] The decorative shell 17 can protect and decorate the lower shell 16. The air outlet 14 is arranged between the air outlet hole 171 and the heat dissipation channel 22. The air outlet 14 has a large flow cross section, so that the part of the heat dissipation element 40 extending out of the heat dissipation channel 22 can be avoided. In this way, the direct contact between the heat dissipation element 40 and the shell 10 can be reduced, so as to avoid the force on the shell 10 from being transmitted to the heat dissipation element 40, so as to improve the protection effect of the heat dissipation element 40. Multiple air outlet holes 171 all correspond to the same air outlet 14, and the air outlet hole 171 has a small flow cross section, so it can hide and decorate the air outlet 14, so as to improve the appearance integrity of the hair removal device on the head 11.

[0064] For example, Figure 5 As shown, the peripheral wall of the air outlet 14 is provided with two first connecting arms 131 extending toward each other, and the two first connecting arms 131 are connected by the second connecting arm 132. Part of the peripheral wall of the air outlet 14, the two first connecting arms 131 and the second connecting arm 132 together enclose a clamping position 13. The two first connecting arms 131 can provide a fixing base for the second connecting arm 132. When the clamping position 13 is clamped with the buckle 21, the second connecting arm 132 directly contacts and cooperates with the buckle 21, thereby improving the matching stability of the clamping position 13 and the buckle 21.

[0065] Specifically, Fig. 9As shown, the heat dissipation shell 20 includes a first wall portion 23, and the first wall portion 23 is provided with a buckle 21; wherein, a force release hole 231 is provided through the first wall portion 23, and the force release hole 231 can be used to release force for the first wall portion 23 during the process of the buckle 21 and the clamping position 13 being clamped. During the process of the buckle 21 and the clamping position 13 being clamped, the first wall portion 23 can release force through the force release hole 231, so that the buckle 21 can be slightly deformed to be clamped with the clamping position 13, thereby preventing the buckle 21 from being broken during the force application process, so as to improve the structural stability of the buckle 21.

[0066] In practical applications, such as Fig. 9 As shown, the force release hole 231 is located on a side of the buckle 21 away from the locking position 13 , so that the first wall portion 23 can release force more accurately when the buckle 21 is subjected to force, thereby improving the force release effect.

[0067] For example, Fig.10 As shown, Fig.10 The partial structural cross-sectional view of an embodiment of the hair removal device of the utility model includes a control element 30, a heat dissipation element 40 and an electrical connector 50. The control element 30 and the heat dissipation element 40 are respectively arranged on two opposite sides of the first wall portion 23. The electrical connector 50 is electrically connected to the control element 30. The electrical connector 50 can pass through the pressure relief hole 231 and be electrically connected to the heat dissipation element 40.

[0068] The control element 30 may be a circuit board, and the control element 30 is installed outside the heat conduction channel 81. One end of the electrical connector 50 is connected to the heat dissipation element 40, and the other end passes through the drain hole 231 to connect to the control element 30, so as to achieve electrical conduction between the control element 30 and the heat dissipation element 40. Installing the control element 30 outside the heat conduction channel 81 can avoid installing the control element 30 and the heat dissipation element 40 in the same space, thereby avoiding the control element 30 from being affected by the high temperature from the heat dissipation element 40, so as to improve the working stability of the control element 30. Passing the electrical connector 50 through the drain hole 231 can avoid the need for the electrical connector 50 to bypass the first wall portion 23 or to open another hole through the first wall portion 23, thereby improving the effective utilization of the drain hole 231.

[0069] Specifically, Fig.11 As shown, Fig.11 This is a structural exploded view of another embodiment of the hair removal device of the utility model. One of the shell wall of the tail 12 and the heat dissipation shell 20 is provided with a clamping column 121, and the other is provided with a clamping hole 25 adapted to the clamping column 121. The heat dissipation shell 20 is clamped with the clamping hole 25 through the clamping column 121, and is limitedly matched with the shell wall of the tail 12. In this way, the connection position of the heat dissipation shell 20 and the outer shell 10 can be increased, and the connection stability can be improved, so as to further improve the installation stability of the heat dissipation shell 20 in the installation cavity.

[0070] For example, Fig.12 and Fig.13 As shown, Fig.12 This is a partial structural diagram of an embodiment of the hair removal device of the utility model; Fig.13 This is a schematic diagram of the internal structure of an embodiment of the hair removal device of the present utility model.

[0071] The head 11 has a skin-contacting portion 111, which is used to contact the part of the skin to be depilated, and the heat dissipation shell 20 includes a second wall portion 24 spaced from the skin-contacting portion 111; the depilatory device also includes: a refrigeration element 60, which is arranged between the skin-contacting portion 111 and the second wall portion 24, and the cold compress surface of the refrigeration element 60 is thermally connected to the skin-contacting portion 111; a heat-conducting element 70, which is at least partially arranged between the refrigeration element 60 and the second wall portion 24, and the heat-conducting element 70 is thermally connected to the heat dissipation surface of the refrigeration element 60; a support member 80, which is arranged between the second wall portion 24 and the heat-conducting element 70, and is connected to the second wall portion 24 and the heat-conducting element 70, and the support member 80 is used to support the heat-conducting element 70; wherein the support member 80 is formed with at least one heat-conducting channel 81, and the heat-conducting channel 81 is used to dissipate heat from the heat-conducting element 70.

[0072] In this embodiment, the refrigeration element 60 can be in many forms, taking the semiconductor refrigeration element 60 as an example. The refrigeration element 60 has a heat dissipation surface and a cold compress surface, and the cold compress surface is used to directly or indirectly adhere to the skin, and is used to cool the skin at the position to be depilated. The heat dissipation surface is used to dissipate heat. The better the heat dissipation effect of the heat dissipation surface, the better the cold compress effect of the cold compress surface. Therefore, the heat of the heat dissipation surface should be dissipated in time. The heat conducting element 70 is connected to the heat dissipation surface to quickly conduct the heat of the heat dissipation surface to the heat conducting element 70, and then the heat conducting element 70 is dissipated through the heat conduction channel 81 of the support member 80, thereby improving the heat dissipation efficiency of the refrigeration element 60.

[0073] The heat conducting member 70 may include a first heat conducting section 71 and a second heat conducting section 72. The first heat conducting section 71 is arranged between the refrigeration member 60 and the second wall portion 24, and the first heat conducting section 71 is thermally connected to the heat dissipation surface of the refrigeration member 60, and the second heat conducting section 72 is thermally connected to the first heat conducting section 71, and the second heat conducting section 72 extends in a direction away from the first heat conducting section 71; the support member 80 is arranged between the second wall portion 24 and the first heat conducting section 71, and is connected to the second wall portion 24 and the first heat conducting section 71. The support member 80 is used to support the first heat conducting section 71, and the heat conducting channel 81 is used to dissipate heat for the first heat conducting section 71.

[0074] Specifically, Fig.12As shown, the support member 80 includes at least two support plates 82, and opposite ends of the support plates 82 are respectively connected to the second wall portion 24 and the heat conducting member 70, and at least two support plates 82 are arranged at intervals, and a heat conducting channel 81 is formed between any two adjacent support plates 82. Multiple support plates 82 can increase the support position of the heat conducting member 70, thereby improving the support stability of the heat conducting member 70. At the same time, multiple support plates 82 can also form multiple heat conducting channels 81 to increase the heat dissipation area of ​​the heat conducting member 70 and improve the heat dissipation effect.

[0075] For example, Fig.13 As shown, one end of the support member 80 is connected to the second wall portion 24, and the other end of the support member 80 is formed with a receiving groove 83 for receiving the heat conductive member 70. The receiving groove 83 can increase the installation area of ​​the heat conductive member 70 on the support member 80 to improve the installation stability of the heat conductive member 70.

[0076] Specifically, Fig.13 As shown, the support member 80 includes a support plate 82, and the support member 80 includes a plate body 84 and a limiting arm 85. The plate body 84 is connected to the second wall portion 24, and the plate body 84 extends in a direction away from the second wall portion 24. The limiting arm 85 protrudes from the periphery of the plate body 84 away from the second wall portion 24, and the limiting arm 85 and the plate body 84 cooperate to form a receiving groove 83.
