Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1, a portable cooling fan includes a housing 10, a control circuit board, a power supply, and a fan.
Referring to fig. 1, 2 and 3, the casing 10 is flat and includes a bottom casing and a face casing covering the bottom casing. The first air inlet 11 is opened on one side wall of the housing 10, the first air outlet 12 is opened on the opposite side wall, the first air inlet 11 faces downwards and the first air outlet 12 faces upwards when the air conditioner is in use. Part of the edge of the first air inlet 11 protrudes outwards to form a first protection corner 111. The first protection corner 111 is preferably disposed at a side of the first air inlet 11 close to the clothes. The first protection corner 111 blocks surrounding clothes to prevent the clothes from being adsorbed to the first air inlet 11. Meanwhile, the first protection angle 111 is formed by protruding a part of the edge of the first air inlet 11, so that the area of the actual air inlet of the first air inlet 11 is enlarged, and the probability that the first air inlet 11 is shielded by the clothes is further reduced.
Be equipped with inner shell 20 in the shell 10, the fan is located in inner shell 20 cover, the fan includes rotor and flabellum, second air intake 21 is seted up to inner shell 20 top surface, second air intake 21 and first air intake 11 intercommunication, second air outlet 22 is seted up to inner shell 20 lateral wall, the outer wall butt of second air outlet 22 makes first air outlet 12 sealed in the inner wall of first air outlet 12, the air flows in from first air intake 11, get into the fan through second air intake 21, promote to second air outlet 22 by the fan and flow out. The top surface of the casing 10 is provided with a plurality of third air inlets 16 for auxiliary air intake. At least one of the first air inlet 11, the second air inlet 21, the third air inlet 16 and the second air outlet 22 is provided with fragrance material 30.
Part of the edge of the second air outlet 22 protrudes outwards to form a second protection corner 121. The second protection corner 121 is preferably disposed at the side of the second air outlet 22 close to the clothes. An acute angle is formed between the air outlet direction of the second air outlet 22 and the bottom surface of the housing 10, so that air flowing out of the second air outlet 22 can be blown to the surface of a human body at a certain inclination angle and spread along the surface of the human body, and the heat dissipation effect is better.
The first air inlet 11 is formed in the side wall of the outer shell 10, the second air inlet 21 is formed in the top surface of the inner shell 20, and the second air outlet 22 is formed in the side wall of the inner shell 20 far away from the first air inlet 11, so that the path of air between the first air inlet 11 and the second air outlet 22 is in a shape of a 'ji'. The air undergoes multiple reversals as it moves through the 'poly' shaped path, each reversal causing the air to be more uniformly mixed, particularly after aromatherapy is applied, with better fragrance diffusion uniformity.
Referring to fig. 4, 5 and 6, the housing 10 is provided with a clip 40 for detachable connection to a human body. When in use, the clamping head is clamped at the waist area of a human body.
The cartridge 40 is detachably coupled to the housing 10. Specifically, at least one guide groove 13 and a limiting groove 14 communicated with the guide groove 13 are formed in the bottom surface of the housing 10, at least one side of the limiting groove 14 is a first limiting inclined surface, a limiting portion 41 opposite to the limiting groove 14 is arranged on the chuck 40, at least one side of the limiting portion 41 is a second limiting inclined surface, the limiting portion 41 is placed in the guide groove 13 and can slide to the limiting groove 14 along the guide groove 13, and the first limiting inclined surface and the second limiting inclined surface are attached to limit the relative position of the housing 10 and the chuck 40. In this embodiment, the number of the guide grooves 13, the limiting grooves 14, and the limiting portions 41 is two, the cross section of the limiting groove 14 is a right trapezoid, and the cross section of the limiting portion 41 is a right trapezoid.
The bottom surface of the shell 10 is also provided with an elastic positioning part 15, the chuck 40 is also provided with a convex backstop part 42, and when the limiting part 41 is placed in the guide groove 13, the elastic positioning part 15 presses the chuck 40 to fall back; when the position-limiting portion 41 slides to the position-limiting groove 14, the elastic positioning portion 15 is ejected and abutted against the retaining portion 42, and at this time, the position-limiting portion 41 cannot slide. If the chuck 40 needs to be removed, the elastic positioning portion 15 is pressed to make the elastic positioning portion 15 fall back, the limiting portion 41 slides downwards until the limiting portion 41 moves out of the limiting groove 14, the limiting portion 41 moves out of the guiding groove 13, and the separation of the chuck 40 and the housing 10 is completed.
Referring to fig. 1 and 2 again, a wind shield 23 is formed by protruding a side of the second air inlet 21 of the inner casing 20 close to the first air outlet 12, and the wind shield 23 is arc-shaped and is used for shielding air flowing in from the first air inlet 11.
The top surface of the housing 10 is further provided with a power button 18, and the power button 18 is electrically connected to the control circuit board.
The power supply is mounted in the housing. In this scheme, the power source is a battery.
The top surface of the shell 10 is provided with a plurality of anti-skidding blocks 17. When the portable cooling fan is placed to the desk top in the reverse direction, the anti-skid blocks 17 play an anti-skid role. The anti-skid blocks 17 are preferably four and are symmetrically distributed on the top surface of the shell 10.
The utility model discloses a portable cooling fan is equipped with on the shell 10 and is used for dismantling the chuck 40 of connecting the human body, conveniently carries and can also liberate both hands simultaneously. The partial edge of the first air inlet 11 protrudes outwards to form a first protection angle 111, and the first protection angle 111 blocks surrounding clothes, so that the clothes are prevented from being adsorbed to the first air inlet 11, and meanwhile, the first protection angle 111 is formed by protruding the partial edge of the first air inlet 11 outwards, so that the actual air inlet area of the first air inlet 11 is enlarged, and the probability that the first air inlet 11 is blocked by the clothes is further reduced. An acute angle is formed between the air outlet direction of the second air outlet 22 and the bottom surface of the housing 10, so that air flowing out of the second air outlet 22 can be blown to the surface of a human body at a certain inclination angle and spread along the surface of the human body, and the heat dissipation effect is better. The outer wall of the second air outlet 22 abuts against the inner wall of the first air outlet, so that the first air outlet is sealed, air enters the fan from the first air inlet 11 and the second air inlet 21, and then is directly pushed to the second air outlet 22 by the fan to flow out, and therefore the structure is compact and the size is small.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
