Embodiment Construction
[0028] Such as figure 1 As shown, a dust-collecting negative pressure vacuum cleaner described in the embodiment of the present invention includes a chassis 1, the upper and lower sides of the chassis 1 are respectively provided with an air guide 2 and an air outlet 3, and the bottom of the chassis 1 An exhaust fan 4 is provided, and the gas enters from the air guide port 2, passes through the entire chassis 1, and is discharged from the air outlet 3.
[0029] The casing 1 is provided with a cylindrical filter element 5, the cylindrical filter element 5 corresponds to the air guide port 2, and forms an air inlet channel therewith, and a plurality of evenly distributed studs are arranged on the upper side of the cylindrical filter element 5 , the stud directly passes through the casing 1 and is fixed with a nut, so that the cylindrical filter element 5 can be detachably installed inside the casing 1, and the replacement is simple.
[0030] Such as Figure 2-3 As shown, the bo...

The invention relates to a dust-collecting type negative pressure vacuum cleaner, which comprises a case, an air guide port and an air outlet are respectively provided on the upper and lower sides of the case, and a cylindrical filter element is detachably arranged in the case. The filter element corresponds to the air guide and forms an air inlet channel with it; the bottom of the cylindrical filter element is provided with a corresponding dust collecting device, and the dust collecting device is detachably suspended in the chassis, and the dust collecting device is detachable. There is an exhaust fan below the device. In the present invention, the filtered dust can fall freely by providing a cylindrical filter element, and at the same time, a dust collecting device is arranged at the bottom of the cylindrical filter element to realize the accumulation of dust, thereby prolonging the service life of the cylindrical filter element and increasing the filtering effect; There is a dust blowing device above the dust device. The dust blowing device slaps the filter screen on the cylindrical filter element and slaps off the dust adsorbed on the filter screen, thereby reducing the situation of dust blocking the filter screen and increasing the service life of the cylindrical filter element.
Description
technical field [0001] The invention relates to air conditioner cleaning equipment, in particular to a dust-collecting negative-pressure dust collector with a dust hopper for dust collection. Background technique [0002] In the field of air-conditioning cleaning, ordinary negative pressure vacuum cleaners use superimposed primary, medium, and high-efficiency filters to complete the dust collection work. The primary, medium, and high-efficiency filters are all rectangular filters with small filtering areas. The three-layer filter is to separate the dust layers, so that the high-efficiency filter only filters small dust, and prevents small dust from clogging the high-efficiency filter, thereby increasing the service life of the high-efficiency filter. [0003] Because the dust content in the working environment is very large, most of it is the dust that has accumulated for one year or even several years and has not been cleaned. Since the filter is the "dust holding" containe...
