Description

Technical Field

[0001] This utility model relates to the field of mosquito repellent technology, and in particular to an electric heating mosquito repellent. Background Technology

[0002] Electric mosquito repellents, also known as electric mosquito coils, are common household or outdoor mosquito control devices. They are mainly divided into liquid mosquito repellent devices and electric mosquito repellent mat devices, depending on the type of mosquito repellent used. Existing electric mosquito repellent mat devices primarily work by placing a slot above a fixed heating element inside the device and limiting the space within the slot to hold the mosquito repellent mat in place.

[0003] US Publication No. 6078728A discloses a volatile carrier for supplying volatile components to a heating device thereby distributing the volatile components. The heating device has a passageway selected from a group consisting of channels, tunnels, chambers, and open slots. The passageway has end openings adapted to receive an inserted volatile carrier to position the volatile carrier near a heat source of the heating device. The volatile carrier comprises: a. a substantially single reservoir block containing the supply of the volatile components; and b. a unidirectional propulsion device by which a user manually advances the reservoir block outside the heat source to expose different portions of the reservoir block to heat. While this technical solution can repel mosquitoes by heating the mosquito repellent pad with a heat source, the heat source is bi-directional, meaning only the heat from one side of the pad is effectively utilized, while the heat from the other side is wasted, resulting in low heat source efficiency. Furthermore, the inconvenience of charging, especially outdoors, significantly impacts the device's battery life. Therefore, an electric mosquito repellent device is provided to address these issues.

[0030] Please see Figures 1-4 As shown, in this embodiment, the housing assembly 11 includes a first housing 111, a second housing 112, and a mounting member 113. The first housing 111 is a hollow cavity with one open end. The second housing 112 is fixedly mounted on the first housing 111, and the two together form a sealed hollow cavity. The circuit board 13, the heating and heat insulation component 14, and the battery assembly 16 are respectively fixedly mounted in this cavity.

The outer side of the housing assembly 11 is covered with a cover 114, which enhances the connection performance of the first housing 111 and the second housing 112.

[0031] Please see Figure 4As shown, specifically, the first housing 111 is provided with a first receiving cavity 1111 and a second receiving cavity 1112. The battery assembly 16 is disposed in the first receiving cavity 1111, and the circuit board 13 and the heating and heat insulation assembly 14 are disposed in the second receiving cavity 1112.

[0032] Please see Figures 1-3 As shown, in this embodiment, a slot 121 is provided through the protective cover 12, and the mosquito repellent sheet 15 is detachably snapped into the slot 121; the protective cover 12 is also provided with multiple perforated slots 122, through which the volatile mosquito repellent agent generated by the heating and heat insulation component 14 heating the mosquito repellent sheet 15 diffuses. In this embodiment,

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, the circuit board 13 is electrically connected to the heating and heat insulation component 14, the battery component 16, the button component 17, the charging interface 18, and the indicator light component 19, respectively.

[0034] Please see Figure 2 , Figure 3 and Figure 5As shown, in this embodiment, the heating and heat insulation assembly 14 includes a heat insulation chamber 141, a heat insulation layer 142, and a heating element 143. The heat insulation chamber 141 is a hollow cavity with one open end, which is fixedly disposed in the second cavity 1112. The heat insulation layer 142 and the heating element 143 are tightly fitted together and fixedly disposed in the heat insulation chamber 141. The mosquito repellent sheet 15 is detachably and tightly fitted to one side of the heating element 143 and disposed opposite to the heat insulation layer 142. The function of the heat insulation chamber 141 is to reduce air convection, thereby improving the heat insulation effect of the heat insulation layer 142 and the heating efficiency of the heating element 143 to a certain extent. The heat insulation layer 142 tightly fits the heating element 143 and completely covers it, so as to minimize the heat dissipation of the heating element 143 on the opposite side of the heat insulation layer 142. In this embodiment, the heat insulation layer 142 includes glass fiber cotton and aluminum foil arranged in sequence. The glass fiber cotton is closely attached to the heating element 143, which minimizes the conduction of heat on the back of the heating element 143. The aluminum foil can effectively reduce the heat on the back of the heating element 143 by heat radiation.

[0035] Please see Figure 5 and Figure 6 As shown, in this embodiment, the heating element 143 includes a heating film 1431 and a heat-conducting plate 1432. The heating film 1431 is fixedly disposed between the heat insulation layer 142 and the heat-conducting plate 1432. The heat-conducting plate 1432 can be in close contact with the mosquito repellent sheet 15. The heat generated by the heating film 1431 is transferred to the mosquito repellent sheet 15 through the heat-conducting plate 1432 for heating. In this embodiment, the heating film 1431 is a thin film with metal foil or metal wire as the internal conductive heating element. After being energized, the temperature of the heating film 1431 will continuously rise, thereby conducting the generated heat sequentially to the heat-conducting plate 1432 and the mosquito repellent sheet 15. The size of the heating film 1431 is smaller than the size of the heat-conducting plate 1432. In other embodiments, the heating element 143 can be a single unit or composed of multiple different heating components. Specifically, the heating element 143 can also be a ceramic heating element or a graphene heating element. In this embodiment, a temperature control resistor 14311 is attached to the heating film 1431 to monitor the temperature of the heating film 1431 in real time.

[0036] Please see Figures 1-3As shown, in this embodiment, the mosquito repellent pad 15 is a pad structure impregnated with mosquito repellent agent. Heated by the heating element 143, it releases the agent to achieve the mosquito repellent function. The battery assembly 16 uses a polymer lithium-ion battery. In this embodiment, the button assembly 17 includes a button body 171 and a button housing 172. The button body 171 is fixedly mounted on the circuit board 12, and the button housing 172 is mounted on the button body 171 and passes through the housing assembly 11 via the button hole 1122. Preferably, the button housing 172 is made of silicone material, which makes a sealed contact with the button hole 1122, thereby improving the waterproof performance of the housing assembly 11 to a certain extent. In this embodiment, the charging interface 18 can be a Micro USB interface, a Type C interface, or a Lightning interface. Preferably, the charging interface 18 uses a Type C interface. Specifically, a waterproof plug 181 is detachably mounted on the charging interface 18, with one end of the waterproof plug 181 mounted on the housing assembly 11, protecting the charging interface 18.

[0037] It should be noted that the specific working process of the electric mosquito repellent 10 of this utility model is as follows: the heating element 143 heats the mosquito repellent sheet 15 placed on it, causing the mosquito repellent agent on the mosquito repellent sheet 15 to evaporate, thereby achieving the mosquito repellent operation; the heating element 143 is insulated by the cooperation of the heat insulation chamber 141 and the heat insulation layer 142, so that most of the heat of the heating element 143 is only conducted to one side of the mosquito repellent sheet 15, thereby greatly reducing the heat waste of the heating element 143 and improving the battery life of the electric mosquito repellent 10 to a certain extent; at the same time, the battery assembly 16 is charged through the charging interface 18, the remaining power of the battery assembly 16 can be easily observed in real time through the indicator light assembly 19, and multiple heating levels can be set through the button assembly 17 to correspond to different target heating temperatures.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the 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.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
