[0024] Embodiment

[0025] As Figure 1-4 shown, this embodiment provides a portable cushion fan, including a lower shell 1. The lower shell 1 is a rectangular box with an open upper end. A spiral air duct 4 is arranged inside the lower shell 1, a fan 5 is arranged inside the spiral air duct 4, an air inlet plate 6 is arranged at the lower end of the lower shell 1, a filter screen 7 is fixed behind the air inlet plate 6, a middle shell 2 is bolted to the top of the lower shell 1. The middle shell 2 is a rectangular plate, the bottom of the middle shell 2 is recessed downward and fixedly connected to the bottom of the lower shell 1. A matching tooth piece 8 protruding upward is arranged at the bottom of the middle shell 2, and an aroma sheet 9 is fixed on the matching tooth piece 8. A rectangular upper shell 3 is fixed to the top of the middle shell 2. The PC filter screen 7 is fixed inside the air inlet plate 6 through a clamping position and glue, playing a role in dust prevention. The aroma sheet 9 is fixed by the matching tooth piece 8 protruding from the middle shell 2 component of the fan to prevent the aroma sheet 9 from being sucked into the air duct during air intake. By setting the aroma sheet 9 or other mosquito repellent sheets, wormwood sheets, etc., mosquitoes can be driven away.

[0026] As a further solution of the present application, a rechargeable battery 10 is arranged on the right side of the spiral air duct 4, and the rechargeable battery 10 is electrically connected to the fan 5.

[0027] As a further solution of the present application, a remote control 11 is arranged outside the lower shell 1. The remote control 11 is provided with buttons and a display screen. The buttons include a power switch, a timing button, and a wind volume button.

[0028] As a further solution of the present application, the spiral air duct 4 is provided with an air outlet 13 upward, and a wind deflector 14 corresponding to the air outlet 13 is provided at the upper end of the lower housing 1.

[0029] As a further solution of the present application, a circuit board 15 is fixedly arranged at the bottom of the spiral air duct 4, and the circuit board 15 is electrically connected to the remote controller 11; there is a charging interface at the top of the remote controller 11 for charging in the use state.

[0030] As a further solution of the present application, two bearings 16 are arranged up and down inside the central axis of the fan 5. The design of the two bearings 16 makes the rotation speed of the fan 5 more uniform, and at the same time, less power can bring out a greater and more stable wind force.

[0031] As a further solution of the present application, as Figure 5 shown, the eight corners of the lower housing 1 and the upper housing 3 are all set to an arc surface 17 structure. The arc surface 17 structure can reduce the friction force with the seat cushion, which is convenient for the placement and removal of the blower on the seat cushion.

[0032] As a further solution of the present application, an opening 18 adapted to the fan 5 is provided in the middle of the middle housing 2.

[0033] Working principle: When in use, after the blower is installed on the seat cushion, by clicking the power button on the blower remote controller 11, the blower power is turned on, and the internal fan 5 starts to rotate. After the fan 5 rotates, the wind enters the spiral air duct 4 in the center of the blower through the air inlet 12 channel. Along with the direction of the air volume being thrown out, the diameter of the spiral air duct 4 changes from small to large, and the position of the outlet is the largest. As Figure 6 shown, a wind deflector 14 is provided at the position of the air outlet 13. The length and interval design of the wind deflector 14 can make the air volume on both sides of the air outlet 13 blow out evenly, and make the air volume avoid the seat belt hole 19 in the middle of the seat cushion, and blow into the seat cushion more smoothly. By clicking the timing button of the remote controller 11, there are three time gears of 30 minutes, 45 minutes, and 60 minutes for adjustment respectively. By clicking the air volume button of the blower remote controller 11, there are three air volume modes: Mode 1 is the low-speed mode, Mode 2 is the high-speed mode, and Mode 3 is the gust mode. The soft gust simulates the natural wind, and the fan 5 will have a strong wind every 30 seconds in the gust mode. There is also a screen display on the remote controller 11. When the timing and air volume buttons are pressed, the screen switches from the power display to the display of the current button adjustment.

[0034] Although the present utility model has been described in detail by referring to the accompanying drawings and in conjunction with the preferred embodiments, the present utility model is not limited thereto. Without departing from the spirit and essence of the present utility model, those of ordinary skill in the art can make various equivalent modifications or substitutions to the embodiments of the present utility model, and these modifications or substitutions should all fall within the scope of the present utility model. / Any person familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present utility model, and they should all be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
