Description

Technical Field

[0001] The utility model relates to a fan, in particular to a waist-hanging fan, belonging to the field of daily necessities. Background Art

[0002] A fan is a mechanical structure that can be used to generate airflow. It is usually composed of a motor and blades arranged on the motor output shaft. When the motor is powered on, the blades rotate to form airflow. Household fans are used to cool people down in hot weather. According to their size, they are divided into three types: floor-standing, desktop and portable. Among them, portable fans are suspended by external fixed structures such as lanyards, buckles, hooks and other suspension structures to achieve portability while freeing the user's hands.

[0003] A waist-hanging fan refers to a portable fan that is hung around the user's waist when in use. In the prior art, the air inlet of a waist-hanging fan is often blocked by clothing due to its hanging position, resulting in a failure of air intake. Clothes need to be frequently arranged so that it can be used normally, which seriously affects the use effect and service life. In addition, due to the limited size of portable fans, their air volume is small, and most fans have a single air outlet direction, which cannot meet the use requirements. Summary of the Invention

[0004] In view of this, the present invention provides a waist-hanging fan to solve the above-mentioned problems existing in the prior art.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A waist-mounted fan comprises a housing, a fan, a circuit board and a power supply arranged in the housing;

[0007] The outer shell includes a main body shell and an upper shell and a lower shell respectively buckled on the upper and lower end surfaces of the main body shell, the upper shell and the lower shell have air outlets, the air outlets are provided with a plurality of air guide blades, and the side walls of the main body shell have at least one hanging buckle and a plurality of air inlet holes;

[0008] The fan, the circuit board and the power supply are electrically connected and fixedly connected to the inner wall of the main shell respectively. The fan output shaft is provided with fan blades. The circuit board is electrically connected to a button embedded in the shell.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, there are two hanging fasteners, which are symmetrically arranged and face opposite directions.

[0011] Furthermore, it also includes an outer cover mounted on the upper edge of the main shell, a through hole is formed through the middle of the outer cover, and an air guide ring is provided on the inner wall of the through hole, which extends obliquely toward the center of the through hole and the direction of air outlet.

[0012] Furthermore, the fan blades are turbine-type fan blades.

[0013] Furthermore, the power supply is a rechargeable power supply, and the power supply is electrically connected to a charging socket embedded in the housing.

[0014] The beneficial effects of the utility model are:

[0015] Compared with the prior art, the utility model arranges the air inlet in a circle on the side wall of the shell, ensuring that the air inlet can still work when the clothes are blocking it, avoiding the air inlet from being blocked and causing the fan to fail to work. It adopts a double air outlet method and provides an outer cover on the upper air outlet. The wind guide ring thereon is used to increase the wind speed. When in use, different air outlet effects are presented at both ends through different hanging directions, enriching the use effect and use environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1-3 As shown, the waist-hanging fan includes a housing, a fan 1, a circuit board 2 and a power supply 3 arranged in the housing;

[0023] The outer shell includes a main shell 4 and an upper shell 5 and a lower shell 6 respectively fastened to the upper and lower end surfaces of the main shell 4. The upper shell 5 and the lower shell 6 have an air outlet 7, and the air outlet 7 is provided with a plurality of air guide blades. The side wall of the main shell 4 has at least one hanging fastener 8 and a plurality of air inlet holes 9.

[0024] The fan 1, circuit board 2 and power supply 3 are electrically connected and fixedly connected to the inner wall of the main shell 4 respectively. The fan blades 10 are set on the output shaft of the fan 1, and the circuit board 2 is electrically connected to the button embedded in the shell.

[0025] When in use, the waist-hanging fan is worn on the user's waist with the hanging buckle 8. After starting, the fan works and blows air from the air outlets 7 of the upper shell 5 and the lower shell 6 respectively, so that the user can have air blown above and below the waist.

[0026] In another embodiment of the present invention, there are two hanging fasteners 8, which are symmetrically arranged and facing opposite directions. Different hanging fasteners 8 can be used to change the direction of the waist-hanging fan after wearing it to meet different blowing needs.

[0028] The provision of the air guide ring 12 changes the air outlet direction of the air outlet 7, increases the wind speed of the air outlet at the upper end, and makes the upper and lower air outlets 7 produce different wind speeds to meet different usage requirements.

[0029] In another embodiment of the present invention, the fan blade 10 is a turbine fan blade 10 .

[0030] In another embodiment of the present invention, the power source 3 is a rechargeable power source 3 , and the power source 3 is electrically connected to a charging socket embedded in the housing.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
