Description

Exhaust device

The present invention relates to an air suction device, and more particularly to an air suction device suitable for a stepless charging vacuum cleaner.

The cleaning principle of the vacuum cleaner is to absorb dust and dry dirt such as wires, paper scraps, hair, etc. from the floor, carpet, walls, furniture and other surfaces that are not easy to remove dirt with a broom by means of suction. Its main components are motors, filter bags (or filters), hoses, extension tubes and nozzles in a variety of shapes. Modern vacuum cleaners vary in accessories. They are designed to remove carpet dirt, rough brush, fine brush, rotating brush, flat nozzle for cleaning the corner, polishing brush for cleaning the floor, and vacuum cleaner. In other respects, such as collecting items, finding small objects and cleaning electrical appliances, the dust is greatly improved.

At present, vacuum cleaners have become very popular for families, especially those who have been covered with carpets on the ground, using dust and dust that are very difficult to remove by general brooms, and more need to use vacuum cleaners to perform cleaning work, but general vacuum cleaners are usually limited by The location of the indoor AC outlet is not free to be used in any corner. Even if the extension cord is added, it is also tied by the wire. It is still not convenient enough to use.

In addition, the portable or mobile vacuum cleaner is too noisy due to the rotation of the fan of the air extracting device, causing discomfort in the ear when used. In addition, when using a hand-held or mobile vacuum cleaner, the driving force of the air extracting device is too large. The vibration of the portable or mobile vacuum cleaner is too large, making it difficult for people to use.

In view of the fact that the conventional vacuum cleaner using the exhaust device lacks an effective method of silencing and shockproof, it is urgent to propose a novel mechanism, which can have a vacuum cleaner that is silenced and shockproof.

One of the aims of the present invention is to provide an air extracting device having a sound absorbing and shockproof for use in a rechargeable vacuum cleaner.

In order to achieve the above object, the present invention is an air extracting device, which is suitable for a rechargeable vacuum cleaner, comprising: a motor; a deflector that engages the motor, the deflector is further provided with a plurality of guiding airflow holes; And coupling the baffle; a muffler cover for sealing the baffle and the leaf fan; and a shock absorbing cover for covering the muffler cover.

The above described objects, features, and advantages of the present invention will become more apparent from the description of the preferred embodiments.

In order to enable your review committee to have a better understanding and understanding of the features, purposes and functions of this creation, the following is a detailed description of the detailed structure of the device and the concept of the design, so that the reviewer can understand the creation. The detailed description is as follows: Fig. 1 shows a front exploded view of an air extracting device according to an embodiment of the present invention. Fig. 2 shows a rear view exploded view of an air extracting device according to an embodiment of the present invention. The pumping The air device is suitable for a rechargeable vacuum cleaner, and includes a motor 11, a deflector 12, a bearing 13, a draft fan 14, a muffler cover 15, and a shock shield 16. The deflector 12 is coupled to the motor 11. The deflector 12 is further provided with a plurality of guiding airflow holes, and the deflector 12 is fixed to the front edge of the motor 11 by at least one screw hole 127. Furthermore, the structure of the air deflector 12 further includes a hollow ring disk 121, and one of the hollow ring disks 121 has an inner ring frame 122, and the inner ring frame 122 is coupled to the plurality of guide vanes 123, and each The guide vanes 123 are arcuate, and each of the guide vanes 123 extends out of the hollow ring disk 121 to be coupled to an outer ring frame 124, and a central aperture of the hollow ring disk 121 extends through the axis of the motor. The core and the plurality of guide vanes 123 are driven by the motor 11 to generate an air flow and guide the direction of the air flow. In addition, the plurality of guiding airflow holes 125 are disposed between the hollow ring disk 121 and the outer ring frame 124, and each of the guiding airflow holes 125 is adjacent to each of the two guiding blades 123. The outer arc portion 123a of each of the guide vanes 123 has an L-shaped connecting portion 126 for connecting the outer arc portion 123a of each of the guide vanes 123 with the outer ring frame 124.

The fan blade 14 is coupled to the deflector 12, and the plurality of air guiding holes 125 on the deflector 12 has a function of guiding the direction of the airflow of the fan blade 14, and the fan blade 14 is further The fan 141 includes a hollow shaft 141a, and a plurality of curved blades 141b are disposed around the hollow shaft 141a. A hollow baffle 142 is coupled to the fan 141 for preventing the plurality of curved blades. When the 141b is rotated, friction is generated with the muffler cover 15. The air extracting device further includes a bearing 13 that is coupled to the hollow shaft 141a of the draft fan 14 to couple the draft fan 14 to the axis of the motor 11.

The muffler cover 15 is configured to seal the deflector 12 and the leaf fan 15 The cover plate 12 and the periphery of the draft fan 14 are covered, so that the sound of the airflow generated by the motor 11 driven by the draft fan 14 can be reduced, thereby reducing the noise decibel of the entire exhaust device. The center of the muffler cover 15 further has a plurality of protruding brackets 151. The anti-vibration cover 16 is configured to cover the muffler cover 15 , and the anti-vibration cover 16 covers the periphery of the muffler cover 15 , thereby suppressing the vibration intensity of the motor 11 driven by the exhaust fan blade 14 and the muffler cover. In turn, the vibration force of the overall air extracting device during operation is reduced. The anti-vibration cover 16 is a hollow ring cover.
