Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a fan with easy-to-clean fan blades. Background Art

[0002] A fan is a commonly used electrical appliance. Existing fans are mainly composed of a protective cover, a mask plate, a motor, a fan blade and other components. The mask plate is connected to the protective cover, and the fan blade is located inside the protective cover. The protective cover protects the fan blade and prevents the high-speed rotating fan blade from contacting with external objects or people, thereby causing damage to objects or people.

[0003] During long-term use of existing fans, a lot of dust will adhere to the surface of the fan blades, so the fan blades need to be cleaned. When cleaning the fan blades, the fan blades need to be disassembled first. When disassembling, the fan mask plate on the fan needs to be disassembled first, and then the fan blades are disassembled from the output shaft of the motor, and the disassembled fan blades are cleaned and then installed back on the fan.

[0004] In traditional fans, the mask plate and the protective cover are often connected by screws, and the fan blades and the output shaft of the motor are also connected by screws, retaining rings and other components. When disassembling the mask plate and the fan blades, tools such as screwdrivers and retaining ring pliers are required, which makes disassembly more troublesome and inconvenient for disassembly and cleaning of the fan blades.

[0006] The purpose of the utility model is achieved through the following technical solutions: a fan that is easy to clean the fan blades, comprising a protective cover, a motor, a mask plate, and a fan blade, wherein the motor is arranged on the protective cover, a fan blade connector is connected to the output shaft of the motor, and a plurality of slots are arranged in the circumferential direction of the fan blade connector; a plug-in portion matching the slot is arranged at one end of the fan blade;

[0007] The mask plate and the protective cover are connected by snaps; a plurality of snaps are provided on one side of the mask plate, and snap grooves corresponding to the snaps are provided on the end surface of the protective cover;

[0008] A wind pressure locking mechanism is arranged on the inner side of the protective cover; when the fan is in the on state, the wind pressure locking mechanism locks the mask plate.

[0009] In the utility model, the mask plate and the protective cover are connected by a snap connection. When installing the mask plate, it is only necessary to insert the snap parts on the mask plate into the snap grooves on the protective cover, and then rotate the mask plate in one direction by a certain angle to clamp the mask plate and the protective cover; when disassembling, it is only necessary to rotate it in the opposite direction by a certain angle, so that the mask plate can be removed. The fan blades and the fan blade connector are connected by plugging, and the fan blades are installed and removed by plugging and pulling. In the utility model, the installation and removal of the mask plate and the fan blades are relatively convenient, and there is no need to use tools such as screwdrivers. The mask plate and the fan blades can be easily and conveniently installed and removed, which facilitates the cleaning of the fan blades. The wind pressure locking mechanism can lock the mask plate when the fan is turned on, thereby preventing the mask plate from accidentally falling off from the protective cover during the use of the fan.

[0010] Preferably, it further comprises a column and a base, wherein the lower end of the column is connected to the base, and the upper end of the column is connected to the motor.

[0011] Preferably, the cross-sections of the slot and the plug-in portion are both T-shaped.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0025] like Figures 1 to 5 As shown, a fan with easy blade cleaning includes a protective cover 3, a motor 6, a mask plate 4, blades 5, a column 2, and a base 1. The motor 6 is arranged on the protective cover 3, the lower end of the column 2 is connected to the base 1, and the upper end of the column 2 is connected to the motor 6.

[0026] The output shaft of the motor 6 is connected to a blade connector 7, which is a cylindrical structure. A plurality of slots 8 are provided in the circumferential direction of the blade connector 7. One end of the blade 5 is provided with a plug-in portion 9 that matches the slot 8. The cross sections of the slot 8 and the plug-in portion 9 are both T-shaped. The blade 5 is connected to the blade connector 7 by plugging.

[0027] The mask plate 4 is snap-connected to the protective cover 3. A plurality of snap-fit ​​members 10 are provided on one side of the mask plate 4, and snap-fit ​​grooves 19 corresponding to the snap-fit ​​members 10 are provided on the end surface of the protective cover 3. The snap-fit ​​members 10 are mushroom-shaped.

[0028] A wind pressure locking mechanism is provided on the inner side of the protective cover 3. When the fan is in the on state, the wind pressure locking mechanism locks the mask plate 4. Among them, the wind pressure locking mechanism includes a first fixed block 12 and a second fixed block 13. The first fixed block 12 and the second fixed block 13 are both arranged at the bottom of the inner side of the protective cover 3. A guide rod 14 is provided between the first fixed block 12 and the second fixed block 13. The guide rod 14 is arranged along the axial direction of the protective cover 3. A slider 15 is slidably connected to the guide rod 14, and a ventilating body 16 and a locking column 17 are provided on the slider 15. The ventilating body 16 is bowl-shaped.

An elastic member 18 is provided between the slider 15 and the first fixed block 12. In this embodiment, the elastic member 18 is a spring. When the fan is turned on, the rotating blades 5 will blow outward, and the wind will blow onto the ventilating body 16 and form wind pressure on the ventilating body 16. Under the action of the wind pressure, the slider moves toward the mask plate 4, and the sliding movement drives the locking column 17 to move. The front end of the locking column 17 is inserted into the locking hole 11 on the mask plate 4, thereby locking the mask plate 4 to prevent the mask plate 4 from being separated from the protective cover 3 during the use of the fan. When the fan is turned off, the wind pressure acting on the ventilating body 16 disappears, and the slider is reset under the action of the elastic member 18.

[0029] In the utility model, the mask plate 4 is connected to the protective cover 3 by a snap connection. When installing the mask plate 4, it is only necessary to insert the snap member 10 on the mask plate 4 into the snap groove 19 on the protective cover 3, and then rotate the mask plate 4 in one direction by a certain angle to clamp the mask plate 4 and the protective cover 3; when disassembling, it is only necessary to rotate it in the opposite direction by a certain angle, so that the mask plate 4 can be removed. The fan blades 5 are connected to the fan blade connector 7 by plugging, and the fan blades 5 are installed and removed by plugging and unplugging. In the utility model, the mask plate 4 and the fan blades 5 are convenient to install and remove, and there is no need to use tools such as screwdrivers. The mask plate 4 and the fan blades 5 can be easily and conveniently installed and removed, which facilitates the cleaning of the fan blades 5.
