Description

Technical Field

[0001] This utility model belongs to the field of mosquito repellent technology, specifically relating to an electric mosquito repellent. Background Technology

[0002] Mosquito infestations are a common problem affecting people's comfort and health in daily life and various activities. Whether in homes, offices, outdoor camping, or temporary rest areas, mosquito bites not only cause itchy and uncomfortable skin but can also transmit various diseases, posing a potential threat to people's quality of life and physical health. To address this issue, various mosquito repellent products have emerged. Among them, mosquito repellents based on the principle of electrothermal evaporation have become a common choice in many scenarios due to their ease of use, stable mosquito-repelling effect, and lack of frequent operation.

[0003] Existing electric mosquito repellent products typically consist of a mosquito repellent liquid, a repellent bottle, and a heater. Their working principle involves connecting the heater to a power outlet to introduce an electric current. The heat energy converted from the electrical energy heats the mosquito repellent liquid inside the bottle, causing the effective mosquito-repelling ingredients in the liquid to evaporate and diffuse into the surrounding air, thus repelling mosquitoes. These products are generally designed to be compact to adapt to different placement needs, reduce space occupation, and facilitate flexible use in various environments.

[0004] However, existing electric mosquito repellent products still have many problems that need to be solved in actual use:

[0005] First, the product lacks stability. Due to its compact design, the product's high center of gravity and limited bottom support area make it prone to tipping over when not in use, during daily movement, or under slight outdoor vibrations. Tipping can lead to mosquito repellent leakage, contaminating surfaces, and may also affect heating efficiency due to poor contact between the heater and the repellent bottle. Furthermore, it can pose safety hazards in damp outdoor environments.

[0006] Secondly, the battery life is poor. Existing mosquito repellent bottles generally have a small capacity, typically only around 45 ml, which, under normal usage, can only maintain a continuous mosquito-repelling effect for about 5 days. Frequent replacement of the mosquito repellent not only increases user costs but also reduces ease of use. Especially at night, during outdoor camping, or in unattended situations, if the mosquito repellent runs out and is not replaced in time, the mosquito-repelling effect is easily interrupted, affecting its effectiveness.

[0007] Secondly, disassembly and storage are inconvenient. Most existing mosquito repellents adopt a one-piece structure design, with tightly connected components and a lack of convenient disassembly mechanisms. During off-seasons or when transport is required, the product cannot be disassembled and folded, taking up considerable storage space and making it inconvenient to store in small spaces such as backpacks or storage boxes. Furthermore, the overall structure makes daily cleaning and maintenance difficult; after long-term use, dust, stains, or outdoor debris on the surface of the components are hard to remove completely.

[0008] Finally, maintenance costs are high and resources are wasted. Because the product has a unibody structure, there is a lack of independent connection and disassembly design between the components. When one part of the structure is damaged, it is impossible to replace or repair the individual faulty part. The entire product must be scrapped, which not only increases the user's operating costs but also causes unnecessary waste of resources.

[0009] In summary, existing electric mosquito repellent products have significant shortcomings in terms of stability, battery life, ease of disassembly, storage, and maintenance, and there is an urgent need for an improved product that can solve these problems. Utility Model Content

The lower edge of the upper shell is provided with a retaining block corresponding to the protrusion, and the retaining block is provided with an upwardly inclined retaining part, which is retained in the retaining groove.

[0019] With the above structural design, the buckle design has strong stability and is not easy to fall off when used outdoors. The greater the weight of the upper shell, the tighter and more stable the buckle becomes.

[0020] Preferably, the inner shell is provided with a mounting plate, the circuit board is mounted on the mounting plate, the lower end face is provided with the mounting port, and the heating ring is located above the mounting port.

[0021] Preferably, the upper shell and the middle shell are spaced apart by a certain distance, and the distance between them is 1-2 cm.

[0036] Example 1

[0037] Please see Figures 1 to 3 An electric mosquito repellent includes a lower shell 1, a middle shell 2, and an upper shell 3, which are detachably connected. The lower shell 1 houses a power supply 4 for load-bearing and positioning. The middle shell 2 has an installation port 5 for mounting a mosquito repellent liquid bottle, and also includes a circuit board 6 and a heating ring 7 connected to the power supply 4 to heat and release the mosquito repellent liquid. The top of the upper shell 3 has a hook 10 for hanging when used outdoors. Therefore, the components of this invention are easy to assemble and disassemble, convenient for storage, maintenance, and replacement. The design of the lower shell 1 provides load-bearing and positioning, ensuring the stability of the mosquito repellent during use. Compared to existing mosquito repellents, the overall structure of this device is larger, allowing for a larger capacity mosquito repellent liquid bottle, thus extending its continuous use time.

[0038] Specifically, the lower shell 1 has a flared structure with its diameter gradually increasing from top to bottom, which ensures that the lower part has a larger size when placed horizontally, thereby improving the stability of the placement and reducing the risk of being tipped over.

[0039] In this embodiment, the lower shell 1 and the middle shell 2 are connected by a threaded connection or a snap-fit ​​connection, and the upper shell 3 and the middle shell 2 are connected by a snap-fit ​​connection. The top of the middle shell 2 has multiple protrusions 2a, and each protrusion 2a has an upwardly inclined retaining groove 2b extending inward from one side. The lower edge of the upper shell 3 has a retaining block 3a corresponding to the protrusions 2a, and the retaining block 3a has an upwardly inclined retaining part 3b, which is engaged within the retaining groove 2b. During installation, the retaining part 3b of the upper shell 3 is aligned with the retaining groove 2b of the middle shell 2, and after rotation, it enters the retaining groove 2b to complete the installation. Because the retaining groove 2b and the retaining part 3b are designed with an inclination, they have better stability after assembly and are less likely to fall off.

[0040] Furthermore, the inner shell 2 is provided with a mounting plate 9, on which the circuit board 6 is mounted, and the lower end face is provided with the mounting port 5, and the heating ring 7 is located above the mounting port 5.

[0041] In this embodiment, the upper shell 3 adopts an arc-shaped eaves structure, which can shield the internal structure and play a waterproof role. At the same time, there is a certain distance between the upper shell 3 and the middle shell 2, and the distance between the distance is 1-2cm, which can ensure that the heated gas can diffuse to the surroundings along the gap, thereby improving the gas diffusion effect.

[0042] In this embodiment, the lower shell 1, middle shell 2 and upper shell 3 are all made of PC+ABS alloy plastic, which is sturdy and durable, and its own weight reaches more than 2KG. It is not easy to tip over outdoors and has a windproof function.

[0043] Example 2

[0044] This embodiment has the same structure as Embodiment 1, except that the bottom of the lower shell 1 is provided with a counterweight, and the counterweight is detachable, which can further improve the stability of the mosquito repellent.
