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...

Abstract

The invention relates to a dust collecting type negative pressure dust suction machine. The dust collecting type negative pressure dust suction machine comprises a machine box, and the upper side and the lower side of the machine box are provided with an air guide opening and an air outlet correspondingly. A barrel-shaped filter element is detachably arranged inside the machine box and corresponds to the air guide opening, and an air inlet channel is formed by the barrel-shaped filter element and the air guide opening. The bottom of the barrel-shaped filter element is provided with a dust receiving device corresponding to the barrel-shaped filter element. The dust receiving device is detachably suspended in the machine box. An exhaust fan is arranged below the dust receiving device. Due to the arrangement of the barrel-shaped filter element, filtered dust can fall down freely, and meanwhile the bottom of the barrel-shaped filter element is provided with the dust receiving device so as to achieve dust gathering, so that the service life of the barrel-shaped filter element is prolonged, and the filtering effect is improved. A dust patting device is arranged above the dust receiving device, the dust patting device pats a filter screen on the barrel-shaped filter element so as to remove dust adsorbed on the filter screen in a patting mode, and therefore the situation that the filter screen is blocked by dust is reduced, and the service life of the barrel-shaped filter element is prolonged.

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...
