Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a motor used for vacuum cleaners. Background Art

[0002] A vacuum cleaner is a household appliance that is mainly used to clean dust, debris and other tiny particles from the surface of the floor, furniture, carpets, etc. It creates a certain vacuum inside the vacuum cleaner through the high-speed rotation of the motor, thereby sucking dust and dirt into the dust bag or dust box inside the vacuum cleaner to achieve the purpose of cleaning. Among them, the motor is the core component of the vacuum cleaner, which is mainly responsible for generating suction and driving the fan to rotate, thereby sucking in dust and debris.

[0003] However, in order to facilitate assembly, traditional vacuum cleaners usually connect the motor and the fan into a module, and a protective cover is provided on the outside of the fan to protect the fan. The protective cover is installed on the outside of the fan by screws, which makes it inconvenient to disassemble the fan and thus inconvenient to clean the fan. If the fan is not cleaned for a long time, the dust collection efficiency is likely to be reduced. In view of the above problems, the inventor proposes a motor for a vacuum cleaner to solve the above problems. Utility Model Content

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 without creative work are within the scope of protection of the utility model.

[0019] Example: Figure 1-5 As shown, the utility model provides a motor for a vacuum cleaner, including a mounting base 1, a mounting cover 2 is fixedly connected to the top of the mounting base 1, a fixing column 3 is fixedly installed inside the bottom end of the mounting base 1, a fixing column 3 is fixedly connected to the middle of the top of the mounting base 1 and located inside the mounting cover 2, a turntable 4 is rotatably connected to the outside of the fixing column 3, a driving end of the mounting base 1 movably passes through the fixing column 3 and the mounting cover 2 and is fixedly connected to a fan 5, a protective cover 6 is provided at the top of the mounting base 1 and located on the outside of the mounting cover 2, and a centrally symmetrically distributed clamping assembly 7 is provided on the turntable 4, and the protective cover 6 and the mounting cover 2 are connected via the clamping assembly 7.

[0020] The clamping assembly 7 includes an arc groove 71, which is provided on the turntable 4. A guide rail 72 is fixedly connected to the side of the top of the mounting seat 1 close to the arc groove 71. A slider 73 is slidably clamped to the top of the guide rail 72. A clamping block 74 with symmetrical distribution of centers is provided at the top of the turntable 4. The bottom ends of the clamping blocks 74 are fixedly connected to limiting columns 75. The limiting columns 75 are slidably clamped in the arc groove 71. The bottom ends of the limiting columns 75 are fixedly connected to the top of the slider 73. The outer side of the protective cover 6 is provided with a clamping groove 76 with symmetrical distribution of centers. The ends of the clamping blocks 74 that are away from each other are movably inserted in the clamping groove 76.

[0021] By adopting the above technical scheme, when the protective cover 6 is installed to the outer side of the mounting cover 2, the snap-fit ​​block 74 is movably inserted into the corresponding snap-fit ​​groove 76 to fix the relative position of the protective cover 6 and the mounting cover 2. When the protective cover 6 needs to be disassembled, one of the snap-fit ​​blocks 74 is pushed inward to make the snap-fit ​​block 74 disengage from the inside of the snap-fit ​​groove 76. By utilizing the cooperation between the arc groove 71 and the limiting column 75, the snap-fit ​​block 74 is pushed inward while driving the turntable 4 to rotate, and at the same time driving the remaining snap-fit ​​blocks 74 to move inward at the same time and disengage from the inside of the snap-fit ​​groove 76, thereby releasing the restriction on the vertical movement of the protective cover 6 and facilitating the disassembly of the protective cover 6.

[0022] The top of the inner wall of the mounting cover 2 is fixedly connected with a fixing plate 77 which is symmetrically distributed in the center. The sides of the clamping blocks 74 which are close to each other are fixedly connected with guide rods 79 . The ends of the guide rods 79 which are away from the clamping blocks 74 are movable and penetrate the corresponding fixing plates 77 .

[0023] By adopting the above technical solution and providing the guide rod 79, it is convenient to guide the centripetal movement of the clamping block 74 and improve the stability of the clamping block 74 when moving.

[0024] A spring 78 is disposed between the fixing plate 77 and the clamping block 74 on one side thereof close to the clamping block 74 . The spring 78 is movably sleeved on the outer side of the guide rod 79 .

[0025] By adopting the above technical solution and providing the spring 78 , it is convenient to reset the clamping block 74 . At the same time, the elastic force of the spring 78 is utilized to make the clamping block 74 and the clamping slot 76 more tightly clamped.

[0026] An air inlet 8 is provided at the middle of the top of the protective cover 6 , and exhaust holes 9 are provided on the outer side of the protective cover 6 and are symmetrically distributed around the center.

[0027] By adopting the above technical solution, by providing the air inlet 8 and the exhaust hole 9, it is convenient for high-pressure airflow to enter from the air inlet 8 and to be discharged from the exhaust hole 9, thereby forming a negative pressure space.

[0028] The sides of the top ends of the clamping blocks 74 that are away from each other are both configured as inclined surfaces.

[0029] By adopting the above technical solution and setting the sides of the top ends of the clamping blocks 74 that are away from each other as inclined surfaces, the protective cover 6 can be installed better.

[0030] Working principle: When cleaning the fan of the vacuum cleaner motor, the module formed by the fixing column 3 and the fan 5 is removed, and then one of the clamping blocks 74 is pushed inwardly, and the centripetal movement of the clamping block 74 is guided by the cooperation between the guide rod 79 and the fixing plate 77, and the spring 78 is compressed to make the clamping block 74 escape from the inside of the clamping groove 76, and the cooperation between the arc groove 71 and the limiting column 75 is used to push the clamping block 74 inwardly, while driving the turntable 4 to rotate, and at the same time driving the remaining clamping blocks 74 to move inwardly at the same time and escape from the inside of the clamping groove 76, thereby releasing the restriction on the vertical movement of the protective cover 6, and then facilitating the removal of the protective cover 6;

[0031] When installing the protective cover 6, the protective cover 6 can be installed by placing the protective cover 6 on the outside of the installation cover 2 and movably inserting the clamping block 74 into the corresponding clamping slot 76. At the same time, the elastic force of the guide rod 79 is used to make the clamping block 74 and the clamping slot 76 more tightly connected.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
