Description

[Technical field]

[0001] The present invention relates to the technical field of vacuum cleaners, and in particular to vacuum cleaners capable of self-dusting. [Background technology]

[0002] With the development of science and technology, vacuum cleaners have become one of the indispensable household electrical appliances in people's daily life. The working principle of a vacuum cleaner is to suck air from the suction port by the high-speed rotation of the motor, generate a certain vacuum in the dust box, and make the dust reach the dust filter bag in the dust box through the floor brush, connecting pipe, handle, hose, and main suction pipe to achieve cleaning. In addition, by arranging different suction heads, the vacuum cleaner can clean the dust in places that are difficult to clean, such as hair and furniture gaps, thereby improving the indoor air quality and maintaining household hygiene. However, after the vacuum cleaner is used, it is necessary to clean the garbage and dust in the dust bucket so as to avoid the problem that the dust accumulates in the filter assembly and the vacuum cleaner's dust suction effect is poor.

[0003] In the conventional vacuum cleaner, a dust blowing passage is provided on the outside of the filter assembly, and the fan assembly blows dust into the dust blowing passage to blow away dust on the inner wall of the dust cup body and the outside of the filter assembly, thereby achieving self-cleaning. However, the conventional vacuum cleaner can only clean the dust on the surface of the filter assembly, and cannot clean the dust attached to the inside of the filter assembly, so that the dust accumulates and the vacuum cleaner's dust suction effect gradually deteriorates.

In the present invention, when the self-dust-removing vacuum cleaner is in a self-dust collection mode, the base station 4 is connected to the housing 1, the base station 4 drives the motor assembly 3 to rotate, the positions of the air suction port 311 and the air exhaust port 312 change, the air suction port 311 is used to communicate with the outside, the air exhaust port 312 communicates with the ventilation passage 21 and the ventilation port 22, the dust removal port 13 is open and communicates with the base station 4, and thus the dust adhering to the filter assembly 2 is blown away and dropped into the base station 4 for collection, thereby avoiding environmental pollution.

[0019] Referring to FIG. 2, the filter assembly 2 includes a filter element 23 and a filter element holder 24, the filter element holder 24 is provided in the housing 1, the filter element 23 is provided in the filter element holder 24, there is a gap between the filter element 23 and the filter element holder 24 which serves as the air passage 21, and the air vent 22 is located in the filter element 23.

[0020] 2 and 4, a connecting bracket 11 and an attachment base 12 are provided in a housing 1, one end of the connecting bracket 11 is connected to the attachment base 12, and the other end of the connecting bracket 11 is connected to a filter assembly 2. The connecting bracket 11 has a communication cavity 111 with both ends open and an air cavity 112 with both ends open. The lower end of the communication cavity 111 communicates with the ventilation port 22 of the filter assembly 2, the lower end of the air cavity 112 communicates with the ventilation passage 21, and the lower end of the housing 1 has a dust suction port 14. When the self-dust-removing vacuum cleaner is in a dust suction mode, the upper end of the communication cavity 111 communicates with the air suction port 311, and gas enters through the dust suction port 14 and then flows out through the filter assembly 2, the communication cavity 111 and the air exhaust port 312 in sequence, thereby realizing gas circulation. The upper end of the cavity 112 is blocked, preventing dust from being directly discharged without passing through the filter assembly 2; and when the self-dust-removing vacuum cleaner is in self-dust-collection mode, the upper end of the communicating cavity 111 and the upper end of the air cavity 112 both communicate with the air exhaust port 312, and gas enters through the air suction port 311 and flows out through the communicating cavity 111, the inside of the filter assembly 2, the air passage 21, and the dust removal port 13 in sequence.

Here, the motor module 32 rotates the blades in conjunction with the motor at high speed, generating air negative pressure in the housing 31 to form a negative pressure difference with the outside atmosphere, and sucking up dust. When the self-dust-cleaning vacuum cleaner is in the dust-suction mode, the baffle 33 blocks the upper end of the air cavity 112, and the gas must pass through the filter assembly 2 to be filtered before entering the communication cavity 111. When the self-dust-cleaning vacuum cleaner is in the self-dust-collecting mode, the driven tooth plate 34 rotates, and the baffle 33 leaves the upper end of the air cavity 112, thus the air outlet 312 communicates with the air cavity 112 and the communicating cavity 111, so that the gas moves the dust particles inside and outside the filter assembly 2 together and simultaneously to the base station 4 for collection.
