Technical Field

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

[0002] Electric fans are widely used in homes and offices as a common cooling device in summer.

In some products, the mosquito repellent liquid heating device and the fan's air outlet structure lack effective coordination, resulting in a limited diffusion range of the mosquito-repellent ingredients and affecting the actual usage effect.

[0022] Reference Figures 1 to 3A mosquito-repellent fan according to an embodiment of the present invention includes a support base 110, on which a fan device 120 is provided. The fan device 120 is oscillating about a horizontal rotation axis. The fan device 120 includes an air inlet side 115 and an air outlet 126. A mosquito-repellent device 130 is provided on the side of the fan device 120 where the air inlet side 115 is located. A first air inlet 124 is provided on the side of the air inlet side 115 near the mosquito-repellent device 130. The support base 110 is provided with a ventilation opening 113 communicating with the mosquito-repellent device 130. The ventilation opening 113 corresponds to the position of the first air inlet 124, so that the mosquito-repellent ingredients can diffuse outward from the ventilation opening 113 and enter the fan device 120 from the first air inlet 124, thereby improving the diffusion efficiency of the mosquito-repellent ingredients and increasing the content of mosquito-repellent ingredients in the air, which is beneficial to improving the mosquito-repellent effect.

[0023] Specifically, refer to Figure 2 The rod body 100 contains an oscillating motor 101, which drives the support base 110 to rotate around a vertical axis, thereby enabling the fan to deliver air in different horizontal directions. The support base 110 includes two support arms 111 located on both sides of the fan device 120. The two sides of the fan device 120 are pivotally connected to the two support arms 111 and can oscillate around a horizontal axis of rotation. An oscillating motor 112 is installed inside one of the support arms 111 to control the oscillation of the fan device 120, thereby achieving air delivery adjustment in different height directions.

[0024] It is understood that the fan assembly 120 includes a front housing 121, a main housing 122, and a rear housing 123. The front housing 121 is located on the air outlet side of the fan and has an air outlet 126 for guiding airflow forward. The rear housing 123 is located on the air inlet side 115 of the fan and has a second air inlet 125 for drawing air in from the air inlet side 115. The main housing 122, as the core structure of the fan, houses components such as the motor and fan blades. The first air inlet 124 extends along the axial direction of the fan assembly, increasing the air inlet area and helping to improve air intake efficiency. The main housing 122 is connected to the support arm 111 of the support base 110 via a pivot structure, allowing the fan assembly 120 to tilt and swing between the support arms 111.

[0025] The mosquito repellent device 130 is mounted on the support base 110, located on the air inlet side 115 of the fan device 120 and below the fan device 120. The mosquito repellent device 130 includes a mounting base 131, which is inserted into the support base 110. A liquid storage bottle 135 containing mosquito repellent liquid, such as mosquito coil liquid, is connected below the mounting base 131. The liquid storage bottle 135 is fixed to the connector 133 of the mounting base 131 by a threaded connection, facilitating disassembly and replacement. A heating chamber 134 contains a heating element. When heated by electricity, the mosquito repellent liquid in the liquid storage bottle 135 evaporates in the heating chamber 134, forming a gaseous mosquito repellent component.

[0026] Understandably, the first air inlet 124 is located above the vent 113. When the fan is working, a negative pressure area is formed on the air inlet side 115. After the mosquito repellent ingredient escapes from the vent 113, it is drawn into the fan through the first air inlet 124 and blown out from the air outlet 126 with the airflow, thus achieving effective diffusion of the mosquito repellent ingredient. Furthermore, the first air inlet 124 extends along the axial direction of the fan device 120. When the fan device 120 tilts, the vent 113 still corresponds to the position of the first air inlet 124. The mosquito repellent ingredient overflowing from the vent 113 can enter the fan device 120 through the first air inlet 124, thereby ensuring that the fan device 120 can still effectively absorb the mosquito repellent ingredient when blowing air at different heights, ensuring a good mosquito repellent effect. Furthermore, the first air inlet 124 is also located on the top of the main housing 122 away from the mosquito repellent device 130, that is, the first air inlet 124 is symmetrically arranged on the upper and lower sides of the main housing 122, which helps to increase the air intake area and improve the effect of air blowing and heat dissipation. Moreover, there is no need to distinguish the orientation during installation, avoiding incorrect installation and improving installation efficiency.

[0027] Furthermore, referring to Figure 3 The mounting base 131 is equipped with a protective sleeve 132, which is located above the connector 133. A heating chamber 134 is formed inside the protective sleeve 132, and a vent 113 is connected to the heating chamber 134, allowing the evaporated mosquito-repellent component to diffuse outwards through the vent 113. To ensure that the mosquito-repellent component can smoothly escape from the vent 113 and enter the fan device 120, the support base 110 is also equipped with an air inlet 114, located on one side of the mounting base 131 and connected to the heating chamber 134. This air inlet 114 is used to maintain a pressure balance inside and outside the heating chamber 134, preventing excessive negative or positive pressure from affecting the evaporation and diffusion of the mosquito-repellent liquid. Furthermore, the top of the protective sleeve 132 is tightly attached to the inner circumferential wall of the vent 113 section of the support base 110, forming a sealed structure to ensure that the mosquito-repellent component mainly diffuses outwards from the vent 113, preventing leakage at other locations.

[0028] In practical use, the user can install the liquid storage bottle 135 onto the mounting base 131. After connecting the power, the mosquito repellent device 130 begins to heat up, and the mosquito repellent liquid gradually evaporates. At the same time, the fan device 120 is activated, and the fan motor drives the fan blades to rotate, drawing in air from the second air inlet 125 and the first air inlet 124. Since the first air inlet 124 corresponds to the vent 113, the escaped mosquito repellent components are directly drawn into the fan device 120 and blown into the indoor space from the air outlet 126 with the airflow, forming an airflow containing mosquito repellent components, thereby increasing the concentration of mosquito repellent components in the indoor air and enhancing the mosquito repellent effect.

[0029] In addition, refer to Figure 4 and Figure 5 The fan device 120 can be tilted up and down by the oscillating motor 112 and rotated horizontally by the oscillating motor 101, thereby expanding the air delivery range and the diffusion range of the mosquito repellent ingredients. It is suitable for different usage scenarios and user needs, effectively improving the utilization rate and diffusion efficiency of mosquito repellent liquid, and overcoming the problems of insufficient diffusion and limited range of mosquito repellent ingredients in traditional mosquito repellent fans.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
