[0001] This utility model relates to the field of ceiling fan technology, specifically to a mosquito-repellent ceiling fan. [Background Technology]

[0002] Currently, ceiling fans on the market only have an airflow function. When mosquitoes bother users in the summer, they need to use additional devices such as electric mosquito repellent liquid and mosquito repellent tablets. These mosquito repellent devices are usually placed on the ground or tabletop, which requires separate placement and affects aesthetics. This is especially problematic for families with children, as children need to be prevented from accessing and playing with them.

[0003] Patent No. "201721017126.5" discloses a novel small ceiling fan structure. This application sets a mosquito repellent sheet in the bottom of the ceiling fan for mosquito repellency, which solves the defect of placing the mosquito repellent device directly on the ground or table. However, when the mosquito repellent sheet is placed in the bottom of the ceiling fan, the mosquito repellent substance emitted by the mosquito repellent sheet inside is difficult to be emitted, resulting in uneven distribution of the mosquito repellent substance and difficulty in achieving a good mosquito repellency effect.

[0004] In view of the above-mentioned technical problems, this utility model is proposed in this study. [Utility Model Content]

[0005] The technical problem to be solved by this utility model is to provide a mosquito-repellent ceiling fan. By setting a mosquito-repellent mechanism at the bottom of the ceiling fan body and setting a fan in the mosquito-repellent mechanism, the mosquito-repellent substance volatilized from the mosquito-repellent sheet can be easily blown out of the cavity. Then, the main fan blade assembly blows the mosquito-repellent substance into the room, realizing whole-room circulation. This solves the problem that the mosquito-repellent substance accumulates in the cavity and is difficult to disperse, resulting in uneven distribution of the mosquito-repellent substance in the room.

[0006] To solve the above-mentioned technical problems, this utility model proposes a mosquito-repellent ceiling fan, including a ceiling fan body and a mosquito-repellent mechanism disposed at the bottom of the ceiling fan body. The ceiling fan body includes an external rotor motor, a main fan blade assembly, and a hanging assembly. The external rotor motor includes a rotor assembly and a stator assembly. One end of the hanging assembly is connected to the stator assembly, and the other end is connected to the ceiling. The main fan blade assembly is connected to the rotor assembly. The mosquito-repellent mechanism includes a housing connected to the bottom of the stator assembly and a fixed cover disposed at the bottom of the housing and detachably connected to the bottom of the housing. A cavity for accommodating a mosquito-repellent sheet is formed between the fixed cover and the housing. A plurality of ventilation holes are formed on the housing to connect the cavity to the room. A fan is provided in the cavity to accelerate the evaporation of the mosquito-repellent substance from the mosquito-repellent sheet and blow the evaporated mosquito-repellent substance into the room through the ventilation holes.

[0007] As described above, a mosquito-repellent ceiling fan has an inner shell connected to its top in the cavity, the fan is disposed in the inner shell, and the inner shell has several through holes.

[0008] As described above, the mosquito-repellent ceiling fan has through holes on the side wall and bottom of the inner shell.

[0009] In the mosquito-repellent ceiling fan described above, the fixing cover is snapped into the outer casing.

[0010] As described above, the mosquito-repellent ceiling fan has a circular cross-section, and correspondingly, the fixed cover also has a circular cross-section. The bottom inner wall of the outer shell is surrounded by several snap-fit ​​protrusions, and the upper outer side of the fixed cover is provided with a slot that snaps into the snap-fit ​​protrusions. The slot includes a vertical guide section and a horizontal locking section. The upper part of the horizontal locking section is formed with a limiting part for restricting the movement of the protrusions in the horizontal locking section.

[0011] As described above, a mosquito-repellent ceiling fan has a receiving groove formed on the fixed cover for accommodating a mosquito-repellent sheet.

[0012] As described above, the mosquito-repellent ceiling fan also includes an auxiliary fan blade assembly on the rotor assembly for agitating the external airflow of the mosquito-repellent mechanism to disperse the mosquito-repellent substance emitted by the mosquito-repellent tablet into the room.

[0013] As described above, a mosquito-repellent ceiling fan includes an auxiliary fan blade assembly that is connected to the lower part of an outer rotor assembly.

Detailed Implementation Methods

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 1-8As shown, this utility model includes a mosquito-repellent ceiling fan, comprising a ceiling fan body 1 and a mosquito-repellent mechanism 2 disposed at the bottom of the ceiling fan body 1. The ceiling fan body 1 includes an external rotor motor 10, a main fan blade assembly 11, and a hanging assembly 12. The external rotor motor 10 includes a rotor assembly 100 and a stator assembly 101. One end of the hanging assembly 12 is connected to the stator assembly 101, and the other end is connected to the ceiling. The main fan blade assembly 11 is connected to the rotor assembly 100. The mosquito-repellent mechanism 2 includes a housing 20 connected to the bottom of the stator assembly 101 and a fixed cover 21 disposed at the bottom of the housing 20 and detachably connected to the bottom of the housing 20. A cavity 22 for accommodating a mosquito repellent sheet 3 is formed between the fixed cover 21 and the housing 20. A plurality of ventilation holes 23 are formed on the housing 20 to connect the cavity 22 to the room. A fan 24 is provided in the cavity 22 for accelerating the evaporation of mosquito repellent substances from the mosquito repellent sheet 3 and blowing the evaporated mosquito repellent substances from the mosquito repellent sheet 3 into the room through the ventilation holes 23.

[0035] In this application, by installing a fan 24 in the cavity 22, the mosquito repellent substance volatilized from the mosquito repellent tablet 3 can be easily blown out of the cavity 22. Then, the main fan blade assembly 11 blows the mosquito repellent substance into the room, realizing whole-room circulation and avoiding the accumulation of mosquito repellent substance in the cavity 22, which makes it difficult to disperse and causes uneven distribution of mosquito repellent substance in the room.

[0036] It should be noted that the structure of each part of the ceiling fan body 1 in this application is conventional technology in the field, and therefore will not be described in detail in this application.

[0037] like Figure 3 , Figure 5 and Figure 6 As shown, as a further solution in this embodiment, to prevent the fan 24 from blowing air onto the mosquito repellent sheet 3 and affecting its operation, the cavity 22 is provided with an inner shell 4 connected to its top. The fan 24 is disposed in the inner shell 4, and the inner shell 4 is provided with several through holes 40. The through holes 40 are also provided on the side walls and bottom of the inner shell 4. By placing the fan 24 in the inner shell 4, the fan 24 can be isolated from the mosquito repellent sheet 3, preventing the mosquito repellent sheet 3 from affecting the operation of the fan 24. Similarly, to facilitate the air blown by the fan 24 to reach the mosquito repellent sheet 3, through holes 40 are also provided at the bottom of the inner shell 4. The through holes 40 at the bottom of the shell allow the fan 24 to blow directly onto the mosquito repellent sheet 3, while the through holes 40 on the side facilitate the blowing of the mosquito repellent substance emitted by the mosquito repellent sheet 3 into the room.

[0038] like Figure 7 , Figure 8As shown, as a further embodiment, the fixing cover 21 is snapped into the outer shell 20. The outer shell 20 has a circular cross-section, and correspondingly, the fixing cover 21 also has a circular cross-section. A plurality of snap-fit ​​protrusions 41 are arranged around the bottom inner wall of the outer shell 20. The upper outer side of the fixing cover 21 has a slot 42 for engaging with the snap-fit ​​protrusions 41. The slot 42 includes a vertical guide section 420 and a horizontal locking section 421. A limiting part 422 for restricting the movement of the snap-fit ​​protrusions 41 within the horizontal locking section 421 is formed on the upper part of the horizontal locking section 421. A receiving groove 423 for accommodating the mosquito repellent sheet 3 is formed on the fixing cover 21. In this embodiment, when placing the mosquito repellent patch 3, the mosquito repellent patch 3 is placed in the receiving groove 423. Then, the fixing cover 21 is aligned with the bottom of the outer shell 20, the fixing cover 21 is pushed up and then rotated, and the locking protrusion 41 falls into the vertical guide section 420. Then, the locking protrusion 41 continues to rotate and enters the horizontal locking section 421 until it can no longer be rotated. Then the fixing cover 21 can be released. Under the action of gravity, the fixing cover 21 will fall, and the locking protrusion 41 will abut against the upper part of the horizontal locking section 421. The limiting part 422 will prevent the locking protrusion 41 from sliding out of the horizontal locking section 421. In order to further prevent the fixing cover 21 from loosening, the upper edge of the horizontal locking section 421 can be set at an angle, and the higher side is connected to the limiting part 422, so that the locking protrusion 41 will be locked on one side of the limiting part 422. When replacing the mosquito repellent sheet 3, push the fixing cover 21 upwards and then rotate it in the opposite direction to move the snap-fit ​​protrusion 41 to the vertical guide section 420, and then it can be removed.

[0039] like Figure 1 and Figure 4 As shown, as a further solution of this embodiment, since the mosquito repellent mechanism 2 is located directly below the ceiling fan body 1, and the wind force in this area is relatively weak, the mosquito repellent substance is still easy to accumulate in this area. Therefore, this application also provides an auxiliary fan blade assembly 5 on the rotor assembly 100 to disturb the external airflow of the mosquito repellent mechanism 2 so as to disperse the mosquito repellent substance emitted by the mosquito repellent sheet 3 into the room. The auxiliary fan blade assembly 5 includes an annular plate 50 connected to the lower part of the rotor assembly 100. The auxiliary fan blade assembly 5 also includes a blade group 51. The blade group 51 is composed of several thin blades 52 that are equally spaced and distributed around the outer edge of the annular plate 50. The cross-section of the thin blades 52 is arc-shaped. There are two sets of blade groups 51, which are respectively distributed on the upper and lower sides of the annular plate 50. The mosquito repellent mechanism 2 is located in the blade group 51 on the lower side of the annular plate 50, and the lower part of the rotor assembly 100 is located in the blade group 51 on the upper side of the annular plate 50. In this application, by setting two sets of blade groups 51, the blade group 51 located on the upper side of the annular plate 50 can carry away the heat generated by the outer rotor during operation, while the blade group 51 located on the lower side of the annular plate 50 can dissipate the mosquito repellent material around the mosquito repellent mechanism 2 into the room, thereby achieving a better mosquito killing effect.
