Description

Technical Field

[0001] This utility model relates to the field of night light technology, specifically a mosquito-killing night light. Background Technology

[0002] In daily life, mosquitoes not only bite people, causing itching and discomfort, but may also spread various diseases, seriously affecting people's quality of life and health. Mosquito-killing night lights, as a device that combines lighting and mosquito killing functions, are widely used in homes, hotels, hospitals and other places due to their convenience and significant effects. They utilize the phototaxis of mosquitoes to attract them, and then kill them through a high-voltage electric grid. At the same time, the soft light of the night light can also meet the needs of nighttime illumination. However, most existing mosquito-killing nightlights have a fixed height. When placed on tables, chairs, bedside tables, or other similar locations, their height is difficult to match the 0.5-1.5 meter height range where mosquitoes are most active, resulting in a significant reduction in mosquito-killing effectiveness and failing to fully utilize the device's function. In terms of storage, existing fixed-height mosquito-killing nightlights are not easy to adjust in height, take up a lot of space when not in use, and due to their exposed structure, they are prone to dust accumulation on the internal high-voltage grid and lighting components, affecting their lifespan and effectiveness. Therefore, a mosquito-killing nightlight is needed to solve the problems existing in the current technology. Utility Model Content

[0003] The purpose of this invention is to provide a mosquito-killing night light to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mosquito-killing night light, comprising a lamp holder, a night light body fixed to the lower end of the lamp holder, a high-voltage electric grid sleeved on the outside of the night light body, and an overlapping and contracting mechanism sleeved on the outside of the high-voltage electric grid. The overlapping and contracting mechanism comprises a transparent protective grille, an internally threaded collar, and an externally threaded sleeve. The transparent protective grille is fixed to the lower end face of the lamp holder, the internally threaded collar is fixed to the lower end face of the transparent protective grille, and the externally threaded sleeve is threadedly connected to the threaded groove of the internally threaded collar.

[0005] Preferably, the internal cavity of the external threaded sleeve is provided with a collection groove, and the inner width of the collection groove is greater than the diameter of the high-voltage power grid.

[0006] Preferably, the side surface of the transparent protective grille is provided with a strip-shaped hollow groove, and the upper end of the transparent protective grille is fixed to the bottom of the lamp holder.

[0007] Preferably, the lower end of the external threaded sleeve is fixed with a support base, and a receiving groove is provided between the external threaded sleeve and the support base.

[0008] Preferably, the internal threaded collar engages with the receiving groove, and both the support base and the side surfaces of the internal threaded collar are provided with anti-slip hand-grooving texture.

[0009] Preferably, the upper end of the high-voltage grid is fixed to the bottom of the lamp holder, and a power-conducting base is provided on the side surface of the lamp holder.

[0010] This utility model provides a mosquito-killing night light, which has the following advantages compared with the prior art: Through a designed overlapping and contraction mechanism, and the threaded connection between the inner threaded collar and the outer threaded sleeve, the overlap distance between the outer threaded sleeve and the transparent protective grille can be flexibly adjusted, thereby adjusting the usage height of the night light. This effectively compensates for the gap between the night light's placement on tables, chairs, bedside tables, etc., and the height range (0.5-1.5 meters) where mosquitoes are active, improving the mosquito-killing effect and adapting to different usage scenarios. With the transparent protective grille and external threaded sleeve, after use, rotating the support base will cause the external threaded sleeve to rotate, so that the transparent protective grille and the external threaded sleeve completely overlap, and the internal threaded collar is embedded in the receiving groove. On the one hand, a relatively sealed space is formed, reducing the accumulation of dust on the night light body and the high-voltage power grid when idle; on the other hand, the overall volume is minimized, making it convenient to store, pack and carry, saving space and facilitating mobile use.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4This utility model provides a mosquito-killing night light, including a lamp holder 1. A night light body 2 is fixed to the lower end of the lamp holder 1. A high-voltage electric grid 3 is sleeved on the outside of the night light body 2. An overlapping and contracting mechanism 5 is sleeved on the outside of the high-voltage electric grid 3. The overlapping and contracting mechanism 5 includes a transparent protective grille 6, an internally threaded collar 7, and an externally threaded sleeve 8. The transparent protective grille 6 is fixed to the lower end face of the lamp holder 1, the internally threaded collar 7 is fixed to the lower end face of the transparent protective grille 6, and the externally threaded sleeve 8 is threaded into the threaded groove of the internally threaded collar 7. A strip-shaped hollow groove 12 is opened on the side surface of the transparent protective grille 6. The upper part of the transparent protective grille 6... The end is fixed to the bottom of the lamp holder 1; after use, rotate the support base 10, which will drive the external threaded sleeve 8 to rotate along the thread groove of the internal threaded collar 7 until the transparent protective grille 6 and the external threaded sleeve 8 completely overlap. At this time, the internal threaded collar 7 is just embedded in the receiving groove 11 of the support base 10, forming a relatively sealed space, which greatly slows down the dust accumulation speed of the night light body 2 and the high voltage grid 3 when idle. In addition, the maximum overlap state between the transparent protective grille 6 and the external threaded sleeve 8 greatly reduces the overall volume, making the night light easier to store and carry, whether at home or when going out.

[0015] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the external threaded sleeve 8 has a collection groove 9 inside, and the inner width of the collection groove 9 is larger than the diameter of the high-voltage grid 3. The lower end of the external threaded sleeve 8 is fixed with a support base 10, and a receiving groove 11 is provided between the external threaded sleeve 8 and the support base 10. The internal threaded collar 7 is engaged with the receiving groove 11. The side surfaces of the support base 10 and the internal threaded collar 7 are provided with anti-slip hand-grooving texture. During use, the overlap distance between the external threaded sleeve 8 and the transparent protective grid 6 can be flexibly adjusted by rotating the internal threaded collar 7, so as to realize the free adjustment of the height of the night light body 2. Since most mosquitoes are active at a height of 0.5-1.5 meters above the ground, this design effectively solves the problem that there is a gap between the night light and the optimal height for mosquito activity when it is placed on a table, chair, or bedside table, and significantly improves the mosquito killing effect.

[0016] Further as Figure 1 As shown, it is worth noting that the upper end of the high-voltage grid 3 is fixed to the bottom of the lamp holder 1, and the side surface of the lamp holder 1 is provided with a power supply 4. When the lamp holder 1 is connected to the power supply through the wire of the power supply 4 and the power switch is turned on, the night light body 2 will light up immediately, providing soft lighting for getting up at night. At the same time, the high-voltage grid 3 is simultaneously powered on, using the light emitted by the night light body 2 to attract mosquitoes. When a mosquito touches the high-voltage grid 3 through the transparent protective grille 6, it will be instantly electrocuted and killed. The mosquito carcass will fall directly into the collection groove 9 of the external threaded sleeve 8 for easy cleaning later.

[0017] The solution has the following working process: Before use, the lamp holder 1 is connected to the power supply through the wire on the power socket 4 and then powered on. After the power switch is pressed, the night light body 2 is powered on and used for nighttime lighting. When the high voltage grid 3 is powered on, when mosquitoes are attracted by the light source of the night light body 2 and come into contact with the high voltage grid 3 through the transparent protective grille 6, they will be electrocuted and killed. The electrocuted mosquito corpses fall into the collection groove 9 of the external threaded sleeve 8 for collection. During use, rotating the inner threaded collar 7 along the outer threaded sleeve 8 can adjust the inner and outer overlap distance between the outer threaded sleeve 8 and the transparent protective grille 6, thereby adjusting the usage height of the night light body 2 according to usage needs; most mosquitoes are active at a height of 0.5-1.5 meters above the ground, and the adjustable height of the night light body 2 effectively makes up for the gap between its placement on indoor tables, chairs, bedside tables and the optimal range of mosquito activity height; After use, rotate the support base 10 to drive the external threaded sleeve 8 to rotate along the thread groove of the internal threaded collar 7 until the transparent protective grille 6 and the external threaded sleeve 8 completely overlap. At this time, the internal threaded collar 7 is embedded in the receiving groove 11 of the support base 10. The lowered transparent protective grille 6 and the external threaded sleeve 8 overlap can create a relatively sealed space for the night light body 2 and the high voltage grid 3, thereby alleviating the situation of dust accumulation on the surface of the night light body 2 and the high voltage grid 3 when idle. In addition, the maximum overlap state of the transparent protective grille 6 and the external threaded sleeve 8 can shrink the overall space occupied. This shrinking volume design makes the night light easy to store and carry in a bag.
