[0040] See Figure 1 and Figure 2In one embodiment of this utility model application, a portable mosquito repellent is disclosed, including a housing 10, a power supply 20, a control component 30, a heating component 40, and a reflector 50. The housing 10 has a first chamber 11 and a second chamber 12. The power supply 20 and the control component 30 are disposed in the first chamber 11. The power supply 20 is electrically connected to the control component 30. The heating component 40 is disposed in the second chamber 12. The heating component 40 is electrically connected to the control component 30.

[0041] The power supply 20 disclosed in this embodiment includes, but is not limited to, devices that can temporarily store electrical energy, such as dry cell batteries, lithium batteries, and storage batteries. The portable mosquito repellent is powered by the power supply 20 to the control unit 30. The control unit 30 transmits electrical energy to the heating unit 40. The heating unit 40 converts electrical energy into heat energy and slowly raises the temperature. No external power supply 20 is needed during the entire working process. It can generate heat continuously, which is beneficial for use in outdoor environments and has the advantage of being easy to carry.

[0042] In this embodiment, the power supply 20 and the control unit 30 are disposed in the first chamber 11, and the heating element 40 and the reflective sheet 50 are disposed in the second chamber 12 with the reflective surface of the reflective sheet 50 facing the heating element 40. This optimizes the space inside the housing 10, allowing the heat generated by the heating element 40 and the heat reflected by the reflective sheet 50 to accumulate in the second chamber 12, thereby reducing the impact on the first chamber 11, protecting the power supply 20 and the control unit 30, and preventing circuit failures or safety issues of the power supply 20 caused by high temperatures.

[0043] Specifically, the heating element 40 divides the second chamber 12 into a first cavity 121 and a second cavity 122; the first cavity 121 is used to accommodate the mosquito repellent sheet; the reflective sheet 50 is disposed in the second cavity 122; the reflective sheet 50 is used to reflect the heat from the heating element 40. By simultaneously releasing heat into the first cavity 121 and the second cavity 122 through the heating element 40, the mosquito repellent sheet disposed in the first cavity 121 releases mosquito repellent components, forming a mosquito repellent barrier; at the same time, the reflective sheet 50 disposed in the second cavity 122 reflects heat back to the surface of the heating element 40, which can reduce heat loss and make the surface temperature of the heating element 40 more stable, maintaining the preset working temperature.

[0044] Therefore, the heat from the heating element 40 is concentrated and radiated toward the first cavity 121, which improves heating efficiency, reduces energy consumption, and increases battery life when working in outdoor environments.

[0045] like Figure 2As shown, this embodiment also takes into account reducing the contact area between the heating element 40 and the housing 10, and places the heating element 40 in the middle of the second chamber 12, thereby reducing the heat transfer to the housing 10 and further reducing meaningless heat loss; at the same time, when used outdoors, the mosquito repellent can be held in hand or placed on a table, reducing the temperature rise of the housing 10, avoiding burns or damage to the table, and improving the safety of use.

[0046] On the other hand, the reflector 50 can also block the heat from the heating element 40 from being transferred to the housing 10, further reducing the temperature of the housing 10 and improving the safety of use.

[0047] In another embodiment of this invention, the housing 10 is disclosed as a mica heat-insulating housing 10. The heating element 40 is disposed within the housing 10, so some heat will inevitably be absorbed by the housing 10. The housing 10, made of mica material, utilizes the unique layered structure and mineral composition of mica to form a low thermal conductivity insulation layer, further preventing heat loss to the surrounding environment, achieving a heat preservation effect, increasing the temperature within the second chamber 12, and improving heating efficiency; simultaneously, it further enhances the safety of the mosquito repellent.

[0048] Specifically, as another embodiment of this application, the reflective sheet 50 is disclosed to include any one of aluminum alloy plate, stainless steel plate, and galvanized steel plate. In this embodiment, the reflective sheet 50 can be manufactured using high infrared reflective materials, and heat reflection effect can be achieved using plates such as aluminum alloy plate, stainless steel plate, and galvanized steel plate.

[0049] It should be noted that this embodiment only lists the types of reflective sheet 50, but the protection scope of this utility model is not limited to this. Other types of reflective sheet 50, as long as they can achieve the technical effects disclosed in this application, can be used as equivalent replacements for the concept of this utility model and should also be within the protection scope of this application.

[0050] like Figure 3 As shown, in another embodiment of this application, an assembly groove 13 is provided on the inner wall of the housing 10. The assembly groove 13 is located on the side of the second cavity 122 away from the heating element 40. The heating element 40 includes a fixing frame 41 and a heating plate 42. The fixing frame 41 is connected to the housing 10. The heating plate 42 is disposed on the fixing frame 41 and electrically connected to the control element 30. A support grid 14 is provided in the assembly groove 13. A support rib 411 protrudes from the side of the fixing frame 41 facing the second cavity 122. The support rib 411 and the support grid 14 respectively abut against both sides of the reflector 50.

[0051] The reflector 50 disclosed in this embodiment will continuously heat up during the process of continuously reflecting heat. Therefore, by clamping the reflector 50 with the support grid 14 and the support ribs 411, the reflector 50 is fixed in the assembly groove 13, reducing contact with the housing 10. This can reduce heat transfer between the reflector 50 and the housing 10, keep the housing 10 at room temperature, and improve the safety of use.

[0052] Specifically, in this embodiment, the shape of the assembly groove 13 can be matched with the shape of the reflector 50, for example, both being square, so that the reflector 50 is assembled in the assembly groove 13, with its edge in contact with the side wall of the assembly groove 13. At the same time, the two sides of the reflector 50 abut against the bearing grille and the support rib 411 respectively, achieving the effect of locking the reflector 50, increasing the stability of the structure, and making it easier to adapt to outdoor use environments with frequent movement.

[0053] For example Figure 3 As shown, in another embodiment of this invention, the heating element 40 and the housing 10 are assembled with screws. The outer edge of the fixing frame 41 is provided with screw holes, and screw posts are provided on the inner wall of the housing 10. The fixing frame 41 and the housing 10 are connected by screws. Furthermore, the fixing frame 41 is annular, with connecting holes on its inner edge. The heating plate 42 is positioned at the center of the fixing frame 41, and the edge of the heating plate 42 extends to the side of the fixing frame 41. Through holes are provided corresponding to the positions of the connecting holes. Bolts or pins are inserted into the through holes and connecting holes to connect the heating plate 42 and the fixing frame 41.

[0054] Based on this, in this embodiment, the area of ​​the central hollow of the fixing frame 41 can be larger than the area of ​​the heating plate 42, and only part of the edge of the heating plate 42 contacts the fixing frame 41. Therefore, the heat transfer between the heating plate 42 and the fixing frame 41 can be reduced, and further, the heat transferred from the fixing frame 41 to the housing 10 can be reduced, so that the heat of the heating plate 42 can be concentrated and transferred to the mosquito repellent sheet, thereby improving the heating efficiency.

[0055] Specifically, as another embodiment of this application, the supporting rib 411 is disclosed to be arranged around the edge of the heating plate 42. In this embodiment, the supporting rib 411 avoids the heating plate 42 to prevent blocking the heat reflected by the reflector 50. Simultaneously, the area between the heating plate 42 and the reflector 50 is extremely hot due to continuous heat transfer and reflection. By avoiding this area, the supporting rib 411 can be prevented from being damaged by high temperatures, thus preventing deformation and improving structural stability.

[0056] Specifically, as another embodiment of this application, a heat-absorbing layer is disclosed on the side of the heating plate 42 facing the reflector 50. This heat-absorbing layer includes any one of a black chrome coating, a black nickel coating, a blackboard paint layer, or a silica sol heat-absorbing coating. The heat-absorbing layer disclosed in this embodiment is used to absorb the heat reflected back from the reflector 50, as well as the heat within the second cavity 122. By providing the heat-absorbing layer, the temperature of the side of the heating plate 42 facing the second cavity 122 is further maintained, reducing heat loss and allowing more heat to dissipate from the side of the heating plate 42 facing the first cavity 121, concentrating the heating of the mosquito repellent sheet, further improving heating efficiency and extending heating time. Using coatings with high heat absorption efficiency and good heat resistance, such as black chrome coating, black nickel coating, blackboard paint layer, or silica sol heat-absorbing coating, can extend the service life of the heating element 40.

[0057] like Figure 2 and Figure 3 As shown, in another embodiment of this application, a slot 412 is provided on the side of the fixing frame 41 facing the first cavity 121; the portable mosquito repellent includes an elastic pressure rod 60, one end of which is inserted into the slot 412, and the other end is bent and facing the heating plate 42, for pressing the mosquito repellent sheet against the heating plate 42.

[0058] In this embodiment, the elastic pressure rod 60 is inserted into the slot 412 and remains stable. The end of the elastic pressure rod 60 is bent and elastic. By abutting against the mosquito repellent sheet, the mosquito repellent sheet is pressed onto the heating plate 42. Therefore, during operation, the heat on the heating plate 42 can be quickly transferred to the mosquito repellent sheet to increase the speed at which the mosquito repellent sheet releases the mosquito repellent ingredients.

[0059] Furthermore, in this embodiment, the mosquito repellent sheet is held between the elastic pressure rod 60 and the heating plate 42, which can improve the stability of the mosquito repellent sheet, reduce displacement, and lower the risk of it falling off.

[0060] like Figure 1 As shown in another embodiment of this application, the side of the housing 10 is provided with an insertion port 15 communicating with the first cavity 121, and the insertion port 15 is used to insert the mosquito repellent pad. The mosquito repellent pad disclosed in this embodiment is a consumable and needs to be replaced periodically; therefore, the insertion port 15 is provided on the side of the first cavity 121 to facilitate the replacement of the mosquito repellent pad. At the same time, it can also increase the connectivity between the first cavity 121 and the surrounding environment, which is beneficial to the diffusion of the mosquito repellent ingredients.

[0061] like Figure 1 and Figure 2As shown in another embodiment of this application, the housing 10 is provided with a plurality of perforated holes 16, and the perforated holes 16 array is arranged on the side of the first cavity 121 away from the heating element 40. The perforated holes 16 disclosed in this embodiment are used to increase the connectivity between the first cavity 121 and the surrounding environment. During operation, the mosquito repellent gas emitted by the mosquito repellent sheet is accelerated to be emitted into the surrounding environment through the perforated holes 16, which is conducive to the rapid formation of a mosquito repellent barrier.

[0062] like Figure 3 As shown in another embodiment of this application, the control component 30 includes a control circuit board 31, a control switch 32, a wiring port 33, and a light emitter 34. The control circuit board 31 is disposed in the first chamber 11 and can be a printed circuit board to centrally connect electrical components such as the power supply 20, the control switch 32, the wiring port 33, and the light emitter 34. The control switch 32 is disposed on the control circuit board 31 and can be a mechanical switch, a touch switch, a voice-activated switch, etc., to function as an open / close circuit.

[0063] The wiring port 33 is located on the control circuit board 31, on the side of the control circuit board 31 away from the second chamber 12. In this embodiment, a data cable can be connected through the wiring port 33 to charge the power supply 20 to replenish power and reuse the mosquito repellent.

[0064] The light emitter 34 is disposed on the control circuit board 31; the light emitter 34 is used to display the remaining power of the power supply 20. Specifically, the light emitter 34 disclosed in this embodiment includes, but is not limited to, light-emitting diodes, mini LED beads, etc.

[0065] In summary, this application discloses a portable mosquito repellent device, including a housing 10, a power supply 20, a control component 30, a heating component 40, and a reflective sheet 50. The housing 10 contains a first chamber 11 and a second chamber 12. The power supply 20 and the control component 30 are located in the first chamber 11 and are electrically connected. The heating component 40 is located in the second chamber 12 and is electrically connected to the control component 30. The heating component 40 divides the second chamber 12 into a first cavity 121 and a second cavity 122. The first cavity 121 is used to accommodate the mosquito repellent sheet. The reflective sheet 50 is located in the second cavity 122, with its reflective surface facing the heating component 40. The reflective sheet 50 reflects the heat from the heating component 40. The reflective sheet 50 disclosed in this embodiment reflects heat back to the surface of the heating component 40, reducing heat loss and stabilizing the surface temperature of the heating component 40, maintaining a preset operating temperature. Therefore, the heat from the heating element 40 is concentrated and radiated into the first cavity 121, which improves heating efficiency, reduces energy consumption, and increases battery life when working in outdoor environments.
