Description

Air circulation fan structure Technical Field The utility model belongs to the technical field of air circulation, and particularly relates to an air circulation fan structure. Background The air circulation fan is mainly used for indoor air circulation, so that indoor air temperature distribution is uniform. An air circulation fan may be used as the fan. For example, chinese patent literature of publication No. CN217999915U discloses a detachable air circulation fan structure, and specifically discloses a detachable air circulation fan structure, which includes a spherical mesh enclosure, a driving assembly, fan blades and a supporting seat. Wherein the front side of the spherical mesh enclosure is detachably provided with a protective mesh cover. Specifically, the protective net cover can be locked on the front end surface of the spherical net cover through screws, and can be mounted on the front end surface of the spherical net cover through a lock catch or a buckle, so that the protective net cover and the spherical net cover can be detachably connected. In addition, the back side of the spherical mesh enclosure is also inwards sunken with a mounting cavity, the mounting cavity is provided with an opening part and faces away from the protective mesh cover, and the opening part of the mounting cavity extends towards the direction of the protective mesh cover to form a mounting opening. The driving component can be detachably arranged in the mounting cavity, and when the spherical mesh enclosure is detached from the driving component, the spherical mesh enclosure can be moved along a linear direction, so that the spherical mesh enclosure is separated from the driving component. Therefore, when the spherical net cover is required to be cleaned, the spherical net cover can be independently disassembled, and the spherical net cover is convenient to be cleaned. The drive assembly includes a mounting housing and a first motor, the mounting housing being detachably connected within the mounting cavity. Further, in order to make the installation casing set up more pleasing to the eye in the installation cavity back whole, the lateral surface of installation casing can set up to be spherical structure to after the equipment, the sphere of installation casing and the outer spherical flush of spherical screen panel form into a complete spherical structure, and make the oral area that the installation casing can fill the installation cavity completely. In order to realize that the drive assembly can be installed, the installation part is arranged at the outer side part of the installation shell and is close to the installation opening, and when the installation part is connected to the supporting seat, the installation part is close to the bottom side of the spherical mesh enclosure, wherein the installation part is provided with a center line A passing through the spherical center of the spherical mesh enclosure. The first motor is fixedly arranged in the mounting shell and forms an integral structure with the mounting shell, a main shaft of the first motor extends into the spherical net cover, an included angle between the axis of the main shaft of the first motor and the central line A is 30-60 degrees, and the fan blade is detachably connected to the main shaft of the first motor. When the circulating fan needs to be disassembled and washed, a user can disassemble the protective net cover and the fan blades one by one, and then loosen the locking piece of the spherical net cover and the driving assembly, so that the spherical net cover can be taken down from the driving assembly along one direction, the spherical net cover, the fan blades and the protective net cover are separated, and the spherical net cover, the fan blades and the protective net cover can be independently disassembled for cleaning, so that the cleaning is more convenient, and the cleaning is cleaner. The installation department is 30 ~60 contained angle scope of the main shaft of first motor, can make the support seat in the bottom of spherical screen panel, can reduce the air-out face of spherical screen panel to the distance of support seat dorsal part, under the circumstances that can dismantle spherical screen panel along a straight line direction, not only make the structure of circulation fan compact, pleasing to the eye to the support atress is balanced, stable. In the technical solution disclosed in the above patent document, in the process of assembling the fan, the housing needs to be connected with the driving mechanism in the supporting seat, and then the driving assembly is installed. And after the shell is assembled on the supporting seat, a motor and the like of the redrive assembly are installed in the shell, so that the installation operation is complex, and the installation is inconvenient. Disclosure of utility model The utility model aims to provide an air circulation fan structure which is used for solving the problem that
