Description

Technical Field

[0001] The utility model relates to the technical field of portable energy storage fans, in particular to a waist-hanging fan. Background Art

[0002] The waist-hanging fans currently on the market have a relatively simple structure. When the fans are hung around the waist, the clothes they wear can easily block the air inlet, causing the fans to not work properly. In severe cases, the clothes will be sucked into the fan blades, causing damage to the clothes and the fan. Therefore, it is necessary to improve the existing waist-hanging fans so that the fans can be used normally. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, the utility model provides a waist-hanging fan, and the specific technical solution is as follows:

[0004] A waist-hanging fan comprises a main unit, a motor, a fan blade, a battery and a control circuit installed inside the main unit, a belt buckle is provided outside the main unit, the fan blade is installed on the motor output shaft, the battery supplies power to the motor through the control circuit and controls the motor to rotate, a protective cover is clamped above the air inlet grille, a cavity is formed between the protective cover and the casing, and an air inlet is left at the bottom to prevent the air inlet from being blocked.

[0005] The shielding cover is in the shape of a shell, with an air inlet bottom hole at its lower end, a hook that is buckled with the host at the edge of the lower end, a hole that is engaged with the hook on the host, and an elastic hook piece at the middle and upper edge of the shielding cover, which can be snapped onto the air inlet of the host.

[0006] The elastic hook piece is a sheet-shaped body, and is an integral structure with the side wall of the barrier cover. A buckle protruding outward is provided at the end of the elastic hook piece, and the hook protrudes upward to form a buckle.

[0007] A clothing buckle is arranged on the upper part of the main body, and the clothing buckle can be used for clamping clothing.

[0008] The bottoms of the clothing buckle and the belt buckle are provided with serrated anti-skid patterns.

[0009] Beneficial effects: The waist-mounted fan of the utility model can provide air volume for local positions such as the waist and back to eliminate local heat for the user. It not only has low energy consumption, but also has sufficient air volume to ensure the use effect. A protective cover is set on the front, which can effectively prevent the air inlet grille from being blocked by foreign objects during use, resulting in a reduction in air intake, thereby affecting the air output, and further improving the use effect.

[0014] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings:

[0015] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the positions or elements referred to must have specific directions, be constructed and operated in specific directions. Therefore, they cannot be understood as limitations on the present invention.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0017] like Figures 1 to 4 As shown, a portable waist-hanging fan includes a host 1, a button 37, a motor, a fan blade 5, a circuit board 7 and a battery 6, wherein the button 37 is installed on the top of the host 1, and a circuit board electrically connected to the button 37 is installed in the host 1. The host 1 includes an upper shell 2 and a lower shell 3, a battery is installed inside the lower shell 3, and a circuit board is installed next to the battery. A clothing buckle 23 and a belt buckle 31 are installed on the outside of the host 1, and an air inlet 25 and an air outlet 33 are arranged on the surface of the host 1. The air inlet 25 and the air outlet 33 are connected with the fan blade chamber 51, and a protective cover 4 is installed on the air inlet 25. A hollow cavity 41 is formed between the protective cover 4 and the host 1, and an air inlet is left at the bottom to prevent the air inlet slot from being blocked.

[0018] A fan blade 5 is installed at the output end of the motor, and the fan blade 5 is installed in the fan blade chamber 51. The battery 6, the circuit board and the motor are electrically connected. The fan blade chamber 51 is installed on the fixing column 37 of the lower housing 3 with screws through the screw hole 71. The upper housing 2 and the lower housing 3 are clamped together through the matching clamping block 35 and the clamping hole 29. The anti-blocking cover 4 is clamped on the top of the upper housing 2. The clamping block 43 and the pin 47 of the anti-blocking cover 4 are respectively installed with the clamping port 27 and the socket 22 on the upper housing.

[0019] The shielding cover 4 is in the shape of a shell, and an air inlet bottom hole is provided at its lower end, a hook 47 is provided at the lower edge to be buckled with the host, a hole is provided on the host to be buckled with the hook, and an elastic hook piece 43 is provided at the middle and upper edge of the shielding cover, and the elastic hook piece 43 can be buckled on the air inlet of the host. The elastic hook piece 43 is a sheet-shaped body, and is an integral structure with the side wall of the shielding cover 4, and a buckle protruding outward is provided at the end of the elastic hook piece, and the hook protrudes upward to form a hook 47.

[0020] When the utility model is used, the belt buckle 31 is clamped on the inside of the pants, the main unit 1 is located on the outside of the pants, and the clothing buckle 23 clamps the top, so that the air outlet 33 faces upward and is located between the back and the top. When working, the fan motor drives the impeller 5 to rotate, and the air enters the cavity 41 from below the anti-blocking cover 4, and then enters the inside of the main unit 1 from the air inlet grille 25. Under the action of the fan blades 5, the air is accelerated in the fan blade cavity 51 and blown out from the air outlet 33. The anti-blocking cover 4 forms a barrier between the clothes and the air inlet 25, effectively preventing the clothes from blocking the air inlet 25 and affecting the air intake. The bottom of the belt buckle 31 is provided with a serrated anti-slip pattern 33, which is used to increase the friction between the belt buckle 31 and the pants to prevent the main unit 1 from sliding.

[0021] The above content is a further detailed description of the utility model in combination with specific preferred implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the protection scope of the utility model.
