[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] Please see Figure 1-6 As shown, a hair removal wax heater for localized body hair removal includes:

[0038] Top cover 1, bottom shell 7, wax storage pot 2, middle frame 3 and heating plate 4;

[0039] The lower shell 7 is provided with a heating plate 4 inside, which is in contact with the bottom surface of the wax storage pot 2. The heating plate 4 is used to heat the wax storage pot 2.

[0040] The bottom of the heating plate 4 is provided with a PCB control board 6. The heating plate 4 and the PCB control board 6 are connected by a plug-in type. The PCB control board 6 and the lower shell 7 are fastened and fixed by a clamping component 704.

[0041] The above technical solution can ensure stability during use and has a high temperature protection function to avoid the risk of burns during use.

[0042] A clamping component 704 is fixedly installed in the inner cavity of the lower shell 7. The PCB control board 6 is clamped and fixed in the inner cavity of the lower shell 7 by the clamping component 704. A charging socket 601 is fixedly connected to one end of the PCB control board 6. An opening that mates with the charging socket 601 is opened on the side wall of the lower shell 7. A working indicator light 602 is fixedly installed on the upper surface of the PCB control board 6.

[0043] Preferably, the clamping component 704 is an elastic buckle or hook fixed to the inner wall of the lower shell 7. The edge of the PCB control board 6 is provided with a slot or hole that matches the clamping component 704. During installation, the PCB control board 6 is pushed into the inner cavity of the lower shell 7 until the protruding part of the clamping component 704 is engaged in the slot or hole on the edge of the PCB control board 6, thereby firmly clamping and fixing the PCB control board 6 in the lower shell 7.

[0044] The plug-in fixed connection between the heating plate 4 and the PCB control board 6 is achieved through a connector 603 and a connector 401. The connector 401 is fixedly disposed on the bottom surface of the heating plate 4, and the connector 603 is fixedly disposed on the upper surface of the PCB control board 6. Through this technical solution, the fixing function is achieved by inserting the connector 401 into the inner cavity of the connector 603, thereby fixing the heating plate 4 on the PCB control board 6.

[0045] The connector 401 is fixedly provided with contacting pieces 402 on both sides, and the connector 603 is fixedly connected with contacting springs 604 on both sides of the inner cavity. With this technical solution, when the connector 401 is inserted into the inner cavity of the connector 603, the contacting springs 604 can press against the contacting pieces 402 due to their elasticity, thereby fixing the connector 401. Furthermore, the contact between the contacting pieces 402 and the contacting springs 604 enables electrical connection, thereby connecting the heating plate 4 and the PCB control board 6.

[0046] Both sides of the inner cavity sidewall of the lower shell 7 are fixedly connected with slots 702, and both sides of the middle frame 3 are fixedly connected with buckles 301. Through this technical solution, the middle frame 3 and the lower shell 7 can be fixed together by the snap-fit ​​of buckles 301 and slots 702, and the snap-fit ​​fixation can facilitate subsequent disassembly.

[0047] A plurality of support frames 701 are fixedly installed in the inner cavity of the lower shell 7. The support frames 701 are used to support the fixed heating plate 4. A plurality of second heat dissipation holes 703 are opened at the bottom wall of the inner cavity of the lower shell 7.

[0048] During assembly, the bottom surface of the heating plate 4 abuts against the support plane of the support frame 701, thereby stably supporting the heating plate 4 at a predetermined height and ensuring that its top surface maintains good contact with the bottom surface of the wax storage pot 2.

[0049] A temperature sensor 5 is fixedly installed on the bottom surface of the heating plate 4. The temperature sensor 5 is electrically connected to the PCB control board 6. Through this technical solution, the temperature sensor 5 can be used to monitor the heating temperature during heating, thereby playing a warning role.

[0050] Preferably, the temperature sensor 5 is embedded or closely fitted into a sensor mounting slot on the bottom surface of the heating plate 4 to ensure the accuracy and real-time performance of temperature measurement. The PCB control board 6 has a preset temperature control program that receives the temperature signal fed back by the temperature sensor 5 and compares it with the preset temperature setting value. When the temperature of the heating plate 4 is detected to reach the set value, the PCB control board 6 can control the heating plate 4 to reduce its power and enter the heat preservation state, and the working indicator light 602 will light up to indicate to the user that heating is complete. When the temperature of the heating plate 4 is detected to exceed the preset safety threshold, the PCB control board 6 will immediately cut off the power supply to the heating plate 4 to prevent overheating and avoid the risk of burns or equipment damage. At the same time, the working indicator light 602 can provide over-temperature warnings through different light states.

[0051] The middle frame 3 is provided with a middle frame fixing ring 303 inside, which is used to place and support the wax storage pot 2. Preferably, the inner diameter of the middle frame fixing ring 303 is slightly larger than the maximum outer diameter of the bottom of the wax storage pot 2, forming a clearance fit or loose fit. The wax storage pot 2 is placed directly inside the middle frame fixing ring 303, and a certain gap is left between the outer wall of the pot and the inner wall of the middle frame fixing ring 303. This clearance fit makes it easy for the user to put the wax storage pot 2 in and out. At the same time, the weight of the wax storage pot 2 itself and its contact with the heating plate 4 below can ensure its stability during the heating process. Preferably, the side of the wax storage pot 2 is provided with an annular limiting ring to limit the placement depth of the wax storage pot 2 and ensure good contact between the bottom of the pot and the heating plate 4.

[0052] A middle frame protrusion 302 is provided on the side wall of the middle frame fixing ring 303. The middle frame protrusion 302 is used to provide an interference fit when the upper cover 1 and the middle frame 3 are closed. Through this technical solution, by closing the upper cover 1 onto the middle frame 3, the middle frame protrusion 302 plays the role of interference connection, so that the upper cover 1 remains fixed when closed.

[0053] Preferably, the inner periphery of the upper cover 1 is provided with an annular inner groove 102 or an elastic slot corresponding to the position of the middle frame protrusion 302; when the upper cover 1 is closed, the middle frame protrusion 302 is partially embedded in the annular inner groove 102 on the inner side of the upper cover 1, and an interference fit is formed by the elastic deformation of the material; or, the middle frame protrusion 302 is engaged with the corresponding elastic slot on the inner side of the upper cover 1, producing an interference fixing effect to ensure the stability of the upper cover 1 when closed.

[0054] The upper cover 1 is provided with a plurality of first heat dissipation holes 101. Through the setting of the first heat dissipation holes 101, excess heat in the wax storage pot 2 during heating can be discharged. At the same time, it has the function of regulating the air pressure inside the wax storage pot 2, so as to avoid the situation of splattering or excessive heating temperature when heating the hair removal wax. The user can apply the heated hair removal wax to the body part where hair removal is required. The wax softens the hair follicle by physical action. The wax is peeled off the moment it solidifies. The peeled hair removal wax will pull the hair out, achieving the effect of fast hair removal.

[0055] In practical use:

[0056] 1. The user places the solid hair removal wax block into the inner cavity of the wax storage pot 2, places the wax storage pot 2 on the middle frame fixing ring 303 inside the middle frame 3, ensures that the bottom of the wax storage pot 2 is in complete contact with the top surface of the heating plate 4, closes the top cover 1, so that the top cover 1 and the middle frame protrusion 302 on the side wall of the middle frame 3 form an interference fit to achieve a stable cover.

[0057] 2. Power the device by connecting the charging socket 601 to the external power supply. After power is on, the PCB control board 6 controls the heating plate 4 to start heating. The working indicator light 602 indicates that heating is in progress. The temperature sensor 5 collects the temperature data of the heating plate 4 in real time and feeds it back to the PCB control board 6.

[0058] 3. When the temperature sensor 5 detects that the temperature of the heating plate 4 has reached the preset working temperature, the PCB control board 6 automatically adjusts the power of the heating plate 4 to enter the heat preservation state. At this time, the working indicator light 602 changes color, and the heat dissipation hole continues to discharge excess heat to maintain the stable air pressure in the wax storage pot 2 and avoid the risk of the pot exploding due to overheating or steam pressure.

[0059] 4. After observing the color of indicator light 602, open the top cover 1 and use the hair removal tool to apply the melted hair removal wax. Apply the wax evenly to the body area where hair removal is needed. After the wax has solidified, quickly peel it off against the direction of hair growth. The wax and hair will come off together.

[0060] 5. If the temperature sensor 5 detects that the temperature of the heating plate 4 exceeds the safety threshold, the PCB control board 6 will immediately cut off the power supply to the heating plate 4, and the working indicator light 602 will turn to the alarm state to prevent burns or equipment damage.

[0061] 6. After use, disconnect the power supply and wait for the equipment to cool down before disassembling the middle frame 3 to clean or replace the wax storage pot 2.

[0062] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
