Description

Mute noise reduction type dust collector structure Technical Field The invention relates to the technical field of dust collectors, in particular to a mute noise reduction type dust collector structure. Background With the development of the age and the improvement of the living standard, dust collection equipment, particularly a household dust collector, has been widely used. A vacuum cleaner is an electric appliance that sucks dust or garbage by generating air negative pressure in a sealed housing using a motor (suction motor/suction motor). The Chinese patent grant bulletin number is CN208988696U, the grant bulletin day 2019 is 06 month 18, a vertical dust collector is disclosed, the vertical dust collector comprises a dust barrel, an upper seat, a dust collection motor, a filter cylinder and a plurality of bottom wheels, wherein the filter cylinder is arranged in the dust barrel, the bottom wheels are arranged at the outer bottom of the dust barrel, an air inlet seat pipe is arranged on the side wall of the dust barrel, the upper end of the dust barrel is opened, the upper seat seals the upper end opening of the dust barrel, the upper seat is clamped with the dust barrel, a motor cavity is arranged in the dust barrel, the dust collection motor is arranged in the motor cavity, the motor cavity is communicated with the inside of the dust barrel, the communicating part of the motor cavity and the inside of the dust barrel is separated by the filter cylinder, an air outlet end of the dust collection motor faces the air outlet, the air inlet end of the dust collection motor faces the dust barrel, a sponge barrel is arranged in the filter cylinder, and the outer side wall of the sponge barrel contacts with the inner side wall of the filter cylinder. The disadvantage of the above patent is that the vacuum cleaner lacks guiding function for the sucked air during operation, which easily causes larger wind noise to the air flow and greatly influences the use experience of the user. In view of the foregoing, there is a need for a silent noise reduction type dust collector structure with good noise reduction effect. Disclosure of Invention The invention provides a mute noise reduction type dust collector structure with good noise reduction effect, which aims to overcome the defect that the prior dust collector has no guiding effect on sucked air and is easy to cause larger wind noise to be generated by air flow. In order to achieve the above purpose, the present invention adopts the following technical scheme: The utility model provides a silence type dust catcher structure of making an uproar falls, includes the frame, install the dirt cup on the frame, be equipped with dust absorption pipe and negative pressure pipe on the dirt cup, the intubate is installed to one of them one end of dust absorption pipe, the other end of dust absorption pipe is linked together with the inside of dirt cup, one of them one end of negative pressure pipe is linked together with the inside of dirt cup, the filter mantle is installed to the port department of one of them end of negative pressure pipe, still be equipped with the device that induced drafts on the frame, the other end of negative pressure pipe is linked together with the device that induced drafts, be equipped with a plurality of wind-guiding blades on the lateral wall of filter mantle, wind-guiding blade interval evenly distributed. When the dust cup is used, the air suction device works, a negative pressure area is formed at the negative pressure pipe, air with garbage is sucked into the dust cup through the dust suction pipe, then the sucked garbage is remained in the dust cup under the blocking of the filter cover, and air flow passes through gaps between adjacent air guide blades on the filter cover and is discharged from the negative pressure pipe. The ventilation gaps are arranged between the adjacent air guide blades, and the air flow can uniformly pass through each ventilation gap through the uniform distribution arrangement of the air guide blades, so that the noise generated during the working of the dust collector is greatly reduced, and the noise reduction effect is good. Preferably, the shape of the filter cover is a bucket shape, the opening of the filter cover is matched with the port of the negative pressure pipe in a clamping manner, the shape of the air guide blade is an arc shape, the air guide blades are distributed annularly about the geometric center line of the filter cover and are uniformly arranged at intervals, one end of each air guide blade is fixed on one side close to the opening of the filter cover, the other end of each air guide blade is fixed on one side close to the bottom of the filter cover, and the width of each air guide blade is gradually reduced from one end to the other end. The clamping mode is simple and convenient, easy to assemble and disassemble, and convenient for later maintenance and repair. Through the shape design of t
