Description
Technical Field
[0001] The utility model relates to a fan, in particular to a rechargeable floor fan. Background Art
[0002] As a common indoor ventilation and cooling device, the floor fan is widely used in various places, such as office buildings, workshops of industrial and mining enterprises, restaurants and hotels, and families, due to its advantages of large air volume and low noise. Especially in the hot summer, the floor fan can not only effectively improve the indoor air circulation through large-range air supply, but also provide a significant cooling effect for users, improving the comfort of the environment. In addition, the floor fan can be used by simply placing it on the ground, which has a certain degree of safety, so it is very popular in families and public places.
[0003] However, traditional floor fans generally rely on 220V mains power supply. Therefore, when in use, their placement positions are restricted by the positions of power sockets. Especially in some outdoor places or where power is inconvenient, the use of floor fans is severely restricted. To solve this problem, fans with charging functions have emerged on the market. Such fans can be used offline after charging, expanding the usage scenarios of the fans.
[0004] Although the fans with charging functions alleviate the problem of power supply restrictions to a certain extent, the existing rechargeable fans usually adopt low-voltage motors for driving. Due to the power limitation of the low-voltage motors, these rechargeable fans can only provide limited power for the rotation of the fan blades during operation, and cannot provide sufficient power for the oscillation device of the fan at the same time. This means that the existing rechargeable fans cannot achieve the oscillation function during use, resulting in a limited air supply range of the fan, and only able to provide air flow in a fixed direction. For scenarios that require covering a large space or being shared by multiple people, the functions of such fans are insufficient and cannot meet the users' needs for comprehensive ventilation.
[0005] In addition, the existing rechargeable floor fans often have a relatively simple structural design and single functions. Except for the basic air supply function, they lack intelligent controls such as multi-angle air direction adjustment, which reduces the user experience to a certain extent. Therefore, it is necessary to make further improvements to it. Content of the Utility Model
[0006] The purpose of the utility model is to overcome the deficiencies of the existing technologies and provide a rechargeable floor fan with a simple structure, convenient use, and capable of realizing oscillating blowing without external power supply.
[0007] The object of the present utility model is achieved in the following manner: A rechargeable floor fan, which includes a base. The base is connected to the fan main body through a vertical rod. A motor is installed in the fan main body, and the motor drives the fan blades in the fan cover to rotate to generate air flow movement. The fan main body includes a support frame. The support frame is connected to the vertical rod through a swing frame. A motor, a storage battery and a main control circuit board are installed in the support frame and connected to each other. An outer shell is sleeved outside the support frame. A control panel and a display panel are installed on the outer shell and connected to the main control circuit board. A battery compartment is arranged in the support frame, and the storage battery is fixedly installed in the battery compartment. An elevation angle adjusting device is further arranged between the support frame and the swing frame. The swing frame includes a bearing seat arranged at the top of the vertical rod.

[0008] The upper end of the swing base is covered with a swing mask. The swing motor is fixedly installed on the swing mask. The driving gear is rotatably installed between the swing base and the swing mask through a rotating shaft.
[0009] The swing motor is a reduction motor.
[0010] The elevation angle adjusting device includes rotating shafts arranged on both sides of the swing frame. Hinge holes are arranged on both sides of the support frame and connected to the rotating shafts. The support frame is hingedly installed on the swing frame through the hinge holes and can swing up and down.
[0011] The elevation angle adjusting device includes elevation angle positioning plates installed on both sides of the support frame. A number of adjusting holes are distributed on the elevation angle positioning plates with the hinge holes as the center. Correspondingly, positioning beads are arranged on the swing frame and buckled in the adjusting holes to control the elevation angle of the fan.
[0012] The storage battery is a lithium battery and is connected to the main control circuit board in series after being connected in multiple sections.
[0013] The beneficial effects of the present utility model are as follows: 1. The structure is simple, the production cost is low, and the market competitiveness is improved. 2.

[0017] The present utility model will be further specifically described below with reference to the accompanying drawings. A rechargeable floor fan includes a base 1, the base 1 is connected to the fan main body through a vertical rod 2, a motor 3 is installed in the fan main body, and the motor 3 drives the fan blades in the fan cover 4 to rotate to generate air flow movement; the fan main body includes a support frame 5, the support frame 5 is connected to the vertical rod 2 through a swing frame 6, a motor 3, a storage battery 7 and a main control circuit board 8 are installed in the support frame 5 and connected, an outer shell 9 is sleeved outside the support frame 5, a control panel 10 and a display panel 11 are installed on the outer shell 9 and connected to the main control circuit board 8; a battery compartment 12 is provided in the support frame 5, and the storage battery 7 is fixedly installed in the battery compartment 12; an elevation angle adjustment device is further provided between the support frame 5 and the swing frame 6; the swing frame 6 includes a bearing seat 61 provided at the top of the vertical rod 2, a swing base 62 is rotatably sleeved on the bearing seat 61, a sector gear 63 is further fixedly installed on the bearing seat 61, and a gear 65 driven by a swing motor 64 is provided in the swing base 62 and meshes with the sector gear 63.
[0018] The upper end of the swing base 62 is covered with a swing mask 66, the swing motor 64 is fixedly installed on the swing mask 66, and the driving gear 65 is rotatably installed between the swing base 62 and the swing mask 66 through a rotating shaft 13.
[0019] The swing motor 64 is a reduction motor.
[0020] The elevation angle adjustment device includes rotating shafts 13 provided on both sides of the swing frame 6, hinge holes 14 are provided on both sides of the support frame 5 and connected to the rotating shafts 13, and the support frame 5 is swingably hinged to the swing frame 6 through the hinge holes 14.
[0021] The elevation angle adjustment device includes elevation angle positioning plates 15 installed on both sides of the support frame 5, a plurality of adjustment holes 16 are distributed on the elevation angle positioning plates 15 with the hinge holes 14 as the center, and correspondingly, positioning beads 17 are provided on the swing frame 6 and snapped into the adjustment holes 16 to control the elevation angle of the fan.
[0022] The storage battery 7 is an 18650 lithium battery, and is connected to the main control circuit board 8 in series after being connected in multiple sections.
[0023] Working principle: During normal operation, the fan in this case is connected to the mains power supply to work, and the mains power supply charges the storage battery while working. When the mains power supply is disconnected, the system is powered by the storage battery to maintain the continuous operation of the fan, so as to facilitate users to use in places where there is a power outage or the mains power supply cannot be used.
[0024] It should be noted that in a fan main unit powered by a storage battery, a brushed or brushless motor is used as the power. Compared with a traditional AC motor, the power and torque of such a motor are smaller than those of the AC motor used with mains electricity. Therefore, there is no DC motor on the market whose tail extends backward to be connected to a reduction gearbox to drive the fan to swing and blow air. Therefore, in this case, an independent swing frame is provided to drive the fan main unit to swing. Among them, the swing frame 6 includes a bearing seat 61 provided at the top of the vertical rod 2, and a swing base 62 is rotatably sleeved on the bearing seat 61. A sector gear 63 is also fixedly installed on the bearing seat 61, and a gear 65 driven by a swing motor 64 is arranged inside the swing base 62 and meshes with the sector gear 63. When the swing motor drives the gear to rotate, since the sector gear is fixed to the vertical column and cannot rotate, the swing motor drives the swing frame to rotate in the reverse direction when working, thereby driving the main unit of the fan to rotate relative to the vertical column, so as to realize the swing and blowing of the fan. Compared with a traditional fan, the swing mechanism in this case works independently. That is, when the user does not use the swing function, the swing mechanism does not work, thus not consuming energy. In a traditional fan, even when the swing function is not used, the fan motor still drives the gearbox of the swing mechanism to rotate, thus wasting some energy. For a fan powered by a storage battery, it is particularly important to save energy consumption and extend its battery life. Therefore, in this case, an independent motor is used to drive the fan to work and swing, which can greatly save energy and improve the efficiency of the fan.
[0025] Furthermore, in order to meet the requirement of the pitch angle when the fan is working, in this case, on both sides of the swing frame 6, there are rotating shafts 13, and hinge holes 14 are provided on both sides of the support frame 5 and are connected to the rotating shafts 13. The support frame 5 is pivotally installed on the swing frame 6 through the hinge holes 14 in a vertically swingable manner. On both sides of the support frame 5, there are elevation positioning plates 15. A number of adjustment holes 16 are distributed on the elevation positioning plates 15 with the hinge holes 14 as the center. Correspondingly, positioning beads 17 are provided on the swing frame 6 and are buckled in the adjustment holes 16 to control the elevation angle of the fan. When the user needs to adjust, only need to swing the main unit forcefully so that the positioning post is buckled with the corresponding height adjustment hole. The elastic buckle structure enables the user to use it immediately after adjustment without operating a locking device, making the adjustment more convenient and fast, so it can be widely promoted and used.
[0026] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the claims of the present invention.
