It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the scope of protection of the utility model.

[0037] refer to Figure 1 and Figure 2 The utility model provides a mosquito repellent, including a mounting base 1 and a heating component 2. The mounting base 1 is provided with a mounting cavity 101; the heating component 2 includes a flexible heating plate 21 and a pair of heat transfer plates 22, the heat transfer plates 22 are installed in the mounting cavity 101, and the pair of heat transfer plates 22 are respectively arranged on both sides of at least part of the flexible heating plate 21, and the heat transfer plates 22 transfer the heat of the flexible heating plate 21 to the mosquito repellent sheet.

[0038] In this embodiment, the heating component 2 includes a flexible heating plate 21 and a pair of heat transfer plates 22. The flexible heating plate 21 is at least partially arranged between the pair of heat transfer plates 22. The flexible heating plate 21 transfers heat to the mosquito repellent sheet through the heat transfer plate 22. The flexible heating plate 21 has a higher heating temperature and can achieve high-precision temperature control. The higher temperature can enhance the volatilization effect of the mosquito repellent sheet and improve the mosquito repellent efficiency.

[0039] Specifically, a pair of heat transfer plates 22 are aluminum plates. A pair of heat transfer plates 22 are suitable for being arranged on both sides of the flexible heating plate 21 and fixedly connected to the flexible heating plate 21 by laser welding. Most of the heating plates of current mosquito repellents are heated by ceramic plates, and the heating temperature can only reach 110°C to 130°C. The heating temperature cannot be well controlled and the heating efficiency is low. The heating component 2 of the present application can accurately control the heating temperature at about 165°C, which greatly improves the heating efficiency. By controlling the current of the flexible heating plate 21 to control its temperature, when the flexible heating plate 21 is heated, the heat will be transferred to the heat transfer plate 22, and then the heat will be transferred to the mosquito repellent plate through the two heat transfer plates 22. There is a temperature sensor on the flexible heating plate 21. When the temperature is controlled at 165°C to 170°C, the mosquito repellent plate can be fully volatilized, and the temperature will not be too high, thereby causing the shell to overheat and scald the user. It is worth noting that the heat transfer plate 22 can also be other heat transfer metals, such as copper. The heat transfer plates 22 are arranged on both sides of the flexible heating plate 21, which can effectively protect the flexible heating plate 21 and prevent accidental damage to the flexible heating plate 21. The heat transfer plates 22 and the flexible heating plate 21 can also be fixedly installed by adhesive or other fixing methods.

[0040] Further, refer to Figure 3 A first placement cavity 102 is also provided in the mounting base 1, and the first placement cavity 102 is suitable for placing a mosquito repellent sheet. An insertion port 111 and an air outlet 112 connected to the first placement cavity 102 are respectively provided on both sides of the mounting base 1. The mounting cavity 101 is connected to the first placement cavity 102, and the heat transfer plate 22 is in direct contact with the mosquito repellent sheet.

[0041] In this embodiment, the installation cavity 101 is connected to the first placement cavity 102, so that the heating component 2 of the installation cavity 101 is in direct contact with the mosquito repellent sheet in the first placement cavity 102, and the contact area between the heat transfer plate 22 and the mosquito repellent sheet is large, which greatly improves the heating efficiency and thus improves the mosquito repellent efficiency.

[0042] Specifically, the mounting base 1 includes a first frame 11, two first placement cavities 102 are arranged in the first frame 11, two groups of insertion ports 111 are also arranged at intervals on the first frame 11, a mounting cavity 101 is further arranged between the two first placement cavities 102, and the two sides of the mounting cavity 101 are respectively connected to the two first placement cavities 102. The insertion port 111 and the air outlet 112 are respectively located on the two sides of the first frame 11, and preferably, the direction of the insertion port 111 is perpendicular to the direction of the air outlet 112. Of course, in a modified embodiment, a group of insertion ports 111 may also be provided, but in this case the heating component 2 can only heat the mosquito repellent sheet on one side, resulting in heat waste on one side of the heating component 2. Therefore, preferably in this embodiment, two groups of insertion ports 111 are also spaced apart on the first frame 11, and both groups of insertion ports 111 can be used to insert mosquito repellent sheets, and the installation cavity 101 is relatively located between the two groups of insertion ports 111, so that the heating component 2 is relatively located between the two groups of insertion ports 111, thereby maximizing the use of the heat of the heating component 2, enhancing the volatilization effect of the mosquito repellent sheet, and greatly improving the mosquito repellent efficiency.

[0043] It is worth noting that reference Figure 5 Two sets of mesh frames 13 are also provided on both sides of the air outlet 112 of the first frame 11, one of the mesh frames 13 is provided with a plurality of fixing posts, and the other mesh frame 13 is provided with a plurality of fixing holes correspondingly, and the fixing posts penetrate the first frame 11 and are fixedly connected to the fixing holes. The specific installation structure of the two sets of mesh frames 13 is not further limited in this application.

[0044] Further, refer to Figures 3 to 6 , and also includes a second frame 12, which is arranged at the bottom of the first frame 11. A second placement cavity 121 is provided in the second frame 12, and the second placement cavity 121 is communicated with the installation cavity 101. A circuit board 122 is provided in the second placement cavity 121, and the flexible heating plate 21 is connected to the circuit board 122.

[0045] In this embodiment, a circuit board 122 is provided at the bottom of the mounting base 1, and the flexible heating plate 21 is connected to the circuit board 122. The circuit board 122 controls the current of the flexible heating plate 21, and then controls the temperature of the flexible heating plate 21. The temperature control of the flexible heating plate 21 is more accurate and sensitive.

[0046] Specifically, a first placement hole 113 is further provided at the bottom of the first frame 11. The first placement hole 113 is relatively located at the bottom of the installation cavity 101. The first placement hole 113 communicates with the first placement cavity 102 and the second placement cavity 121. The bottom of the heat transfer plate 22 is suitable for being placed in the first placement hole 113, and the flexible heating plate 21 is suitable for being connected to the circuit board 122 through the first placement hole 113. The thickness of the heat transfer plate 22 is adapted to the thickness of the first placement hole 113, so that the bottom of the heat transfer plate 22 is clamped and fixed in the first placement hole 113. A fixing hole is further provided at the top of the heat transfer plate 22. The fixing member passes through the fixing hole and then connects to the first frame 11, so that the top of the heat transfer plate 22 is fixedly installed on the first frame 11. In a modified embodiment, a fixing groove is further provided at the top of the heat transfer plate 22, and a fixing column is provided on the first frame 11. The fixing column is matched with the fixing groove and installed. There are various ways to fix the flexible heating plate 21, which will not be described in detail in this application.

[0047] Further, refer to Figure 2 The flexible heating plate 21 includes a heating portion 211 and a connecting portion 212. The heating portion 211 is arranged between a pair of heat transfer plates 22 and arranged in the installation cavity 101; the connecting portion 212 is suitable for passing through the first placement hole 113 and connecting the heating portion 211 and the circuit board 122. The connecting portion 212 is at least partially folded and arranged in the second placement cavity 121.

[0048] In this embodiment, the connecting portion 212 is at least partially folded and arranged in the second placement cavity 121, so that the heat transfer plate 22 and the heating portion 211 sandwiched therebetween are movable relative to the circuit board 122, thereby preventing the connecting portion 212 from being separated from the circuit board 122 during installation, resulting in poor contact between the flexible heating plate 21 and the circuit board 122 and malfunctioning, thereby improving the safety of the installation of the flexible heating plate 21.

[0049] Specifically, the heating part 211 is completely sandwiched between a pair of heat transfer plates 22. The heating part 211 is square, which greatly increases the heating area of ​​the heating part 211. At the same time, there is still a certain distance between the heating part 211 and the top and bottom of the heat transfer plate 22. The part of the heat transfer plate 22 that is not in contact with the heating part 211 is fixedly connected to the first frame 11 to prevent the first frame 11 from being damaged due to excessive temperature, thereby increasing the connection strength between the heat transfer plate 22 and the first frame 11. At the same time, when the mosquito repellent shakes, the connecting part 212 folded in the second placement cavity 121 can also play a buffering role to prevent the connecting part 212 from being pulled and broken. The bottom of the heat transfer plate 22 is set in the first placement hole 113, and the connecting part 212 passes through the first placement hole 113 and then connects to the circuit board 122. Preferably, the flexible heating plate 21 is also provided with a temperature sensor 214. The specific position of the temperature sensor 214 is not further limited in this application. In this embodiment, the temperature sensor 214 is arranged at the top of the connecting portion 212 and is spaced apart from the heat transfer plate 22. The temperature detection is more accurate and the processing is simpler. Of course, the temperature sensor 214 can also be arranged on the heating portion 211, and a hole is opened on the heat transfer plate 22.

[0050] Further, refer to Figure 4 and Figure 5 A second placement hole 114 is further provided at the bottom of the first frame body 11 . The second placement hole 114 communicates with the first placement cavity 102 and the installation cavity 101 . An indicator light is provided in the second placement hole 114 , and the indicator light is connected to the circuit board 122 .

[0051] In this embodiment, the indicator light can remind the user that the flexible heating plate 21 has started working, so that the user can know and be alert; and the indicator light can display the status of the mosquito repellent tablet, which is helpful for the user to judge the remaining content of the mosquito repellent tablet.

[0052] Specifically, there are two heating components 2, and the two heating components 2 are sequentially arranged in the installation cavity 101 along the insertion direction of the insertion port 111. The two heating components 2 have higher thermal conductivity and better heat uniformity. The indicator light is arranged along the air outlet 112 of the first frame 11 and is relatively located between the two heating components 2. The wire of the indicator light passes through the second placement hole 114 and is connected to the circuit board 122.

[0053] Furthermore, the flexible heating plate 21 is provided with a plurality of first positioning holes 213 , and the heat transfer plate 22 is provided with a plurality of second positioning holes 221 . The first positioning holes 213 match the second positioning holes 221 , so that the flexible heating plate 21 and the heat transfer plate 22 are accurately installed.

[0054] In this embodiment, the first positioning hole 213 of the flexible heating plate 21 matches the second positioning hole 221 of the heat transfer plate 22, which facilitates the relative positioning of the flexible heating plate 21 and the heat transfer plate 22, and further facilitates the fixed connection between the flexible heating plate 21 and the heat transfer plate 22, thereby preventing the heating portion 211 of the flexible heating plate 21 from being exposed to the heat transfer plate 22, thereby improving the assembly efficiency of the flexible heating plate 21 and the heat transfer plate 22.

[0055] Specifically, a battery shell is further provided at the bottom of the second frame 12, and a battery is provided in the battery shell, and the battery is connected to the circuit board 122. During assembly, the flexible heating plate 21 is placed between a pair of heat transfer plates 22, and the first positioning hole 213 of the flexible heating plate 21 and the second positioning hole 221 of the heat transfer plate 22 are aligned and then fused by a laser welding process, and then the heating component 2 is placed in the mounting cavity 101 of the mounting seat 1 through the first placement hole 113 at the bottom of the mounting seat 1, and then the air outlet 112 of the mounting seat 1 is covered by a pair of mesh frames 13, and the mesh frames 13 are fixed by screws, and finally the circuit board 122 is installed in the second placement cavity 121 of the mounting seat 1, and the connection part 212 of the flexible heating plate 21 is folded in the second placement cavity 121 of the mounting seat 1, and then the mounting seat 1 and the battery shell are fixed by screws, and finally the quick hook top cover is installed on the mesh frame 13, and the mosquito repellent is installed. During operation, two first placement cavities 102 are provided in the middle of the mounting base 1 for placing mosquito repellent sheets. The mosquito repellent sheets are heated by the heating component 2, so that the mosquito repellent substances can be emitted through the mesh holes on the mesh frame 13 to achieve the mosquito repellent effect. Moreover, the gap between the two first placement cavities 102 is equivalent to the thickness of the mosquito repellent sheet. When the mosquito repellent sheet is inserted into the placement bin, the mosquito repellent sheet is in close contact with the two heat transfer plates 22, so that the heat can be transferred to the mosquito repellent sheet in the first time, thereby giving full play to the effect of the mosquito repellent sheet.

[0056] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
