Description

A fast switching structure of air duct for Hypa self-cleaning vacuum cleaner

technical field

The invention relates to the field of small household appliances, in particular to an air duct quick switching structure for a Hypa self-cleaning vacuum cleaner.

Background technique

The working principle of the vacuum cleaner is to use the motor to drive the blades to rotate at high speed, generate air negative pressure in the sealed shell, and absorb the surface of the carpet, floor, wall and other objects with dust, and the dust is sucked into the dust along with the air. After the separation component, the dust is filtered by the Hypa in the dust-air separation component and collected by the dust bucket, and the filtered clean air is discharged out of the vacuum cleaner body.

After the Hypa has been working for a period of time, a large amount of dust is adsorbed on the surface of the dust collecting bucket. A large amount of dust adheres to the surface of the Hypa, which will block the tiny filter holes on the surface of the Hypa, thereby affecting the filtration of the Hypa. The current vacuum cleaners on the market have the following problems: On the one hand, the existing vacuum cleaners lack the function of self-cleaning the Hypa. Generally, after the Hypa is clogged, the Hypa will be slapped to remove debris after the machine is disassembled. , or directly replace the Hypa after disassembly, either way will take a lot of cleaning time, and the latter will directly lead to the replacement cost of consumables; on the other hand, even if the existing vacuum cleaner is equipped with Hypa self-cleaning function , also adopts the electromagnetic relay structure, that is, mechanically beats the hypa, so that the dust on the surface of the hypa shakes off into the dust collection bucket. Complicated and expensive to use.

For this reason, our company has developed a self-cleaning vacuum cleaner, which uses two air ducts and two motors to divide the Hypa into two, and the two motors work at the same time, so that half of the Hypa can filter dust in the forward direction. When dust is removed, the other half of the Hypa will carry out reverse air blowing and dust removal, and the existing air duct switching structure, on the one hand, is bloated and complex in structure, on the other hand, the wind energy loss is too large during the switching process of the air duct, resulting in high noise , small wind and other issues. In view of this, it is necessary to develop a fast air duct switching structure for the Hypa self-cleaning vacuum cleaner to solve the above problems.

Limited by the limiting plate 1357.

Take the communication between the right guide air duct 1322 and the confluence port 1353 as an example to further elaborate. Referring to Fig. 3 , there is no air flow in the left air guide channel 1312, the left wind deflector 181 is in a natural drooping state, the air flow in the right air guide channel 1322 flows in the direction of arrow B, and the right air guide plate 182 is blocked by the right air guide channel. The airflow at 1322 is pushed to a horizontal state, and the left windshield 181 is restricted by the left front limiting plate 1354 and the left rear limiting plate 1356 because of its tendency to rotate to the left, so that the left air guide duct 1312 is blocked by the left windshield 181 Blocked, the airflow flowing into the air duct switching channel 135 is blocked by the left windshield 181 and can only flow into the confluence port 1353 .
