Background

The use of vacuum cleaners has become increasingly popular. With the development of science and technology, dust collectors are breaking through their own shortcomings. As a core component of a vacuum cleaner, the cleaning of a high-efficiency hepa filter has been a great problem for consumers. Whether water washing or beating or blowing, as shown in figure 1, requires access to a dirty filter and faces secondary contamination with dust. The consumer is therefore quite resistant to cleaning the filter. However, if cleaning is not performed, the cleaning efficiency of the cleaner is greatly reduced. Therefore, a structure for cleaning the filter without disassembling the filter is very important for consumers.

For a vacuum cleaner, the larger the area of the filter, the less frequently cleaning is required and the more dust is sucked at one time. It is therefore generally desirable to make the number of pleats N and the pleat height H of the hpa as large as possible, as shown in fig. 2. The larger the H is, the more difficult the dust embedded into the root of the filter is to clean, and no matter the dust is washed by water, brushed by a small brush or stirred by a strip, the dead angles are difficult to contact in a mechanical mode.

Detailed Description

The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.

As shown in fig. 3-7, the utility model provides a self-cleaning mechanism of vacuum cleaner, which comprises a cleaner main body 4, a HEPA filter 5 arranged in the cleaner main body, and an air duct system, wherein the air duct system comprises a valve 1, an air duct 2 and a HEPA frame air inlet grid 3;

the valve 1 is arranged on the dust collector main body, the HEPA frame air inlet grid 3 is arranged in the HEPA filter, and the valve 1 and the HEPA frame air inlet grid 3 are communicated through the air duct 2.

The utility model discloses an utilize the vacuum that forms when the dust catcher motor operates, designed a ducting system, when the main suction inlet 41 that lies in on the dust catcher main part 4 was plugged up, opened this valve 1, inside the outside air directly supplemented the filter, the internal and external vacuum that forms of hepa was poor, when the pressure of inside was far greater than external pressure this moment, just can shake off the dust of the external adhesion of hepa, the effect can be more obvious if relapse several times.

The working principle is explained as follows:

during normal operation, the valve 1 is in a closed state under the action of the elastic element 12, the main suction port part forms vacuum when the fan runs at high speed, dust and air are sucked into the machine along the main suction pipe under the action of the vacuum, part of dust is adhered to the HEPA 51 after being filtered by the HEPA 51 in the HEPA filter 5, and part of dust falls into the dust barrel 42.

When the dust adsorbs to a certain degree, the sea handkerchief 51 is blocked, and the resistance grow, and the vacuum degree reduces in the dust bucket 42, and the amount of wind reduces, and suction weakens, and suction k vacuum plating the amount of wind, clears up sea handkerchief 51 this moment, and the operation mode is:

block up main suction inlet 41, inside the biggest negative pressure that can form of back machine is blocked up to main suction inlet 41, the internal and external vacuum degree of sea handkerchief 51 also can reach certain balance, beat button 11 several times repeatedly this moment, through beating button 11, valve 1 can be opened, outside air can switch on to inside the sea handkerchief 51 along wind channel 2, because inside and the external world of sea handkerchief 51 communicates with each other this moment, the inside pressure of sea handkerchief 51 can be higher than the sea handkerchief 51 outside, under the repetitive action of this pressure, the last adsorbed dust of sea handkerchief 51 can be shaken off to the dirt bucket 42 in, thereby clear up sea handkerchief 51 under the condition of not opening the dirt bucket.

The following are preferred embodiments:

1. the vacuum degree of the motor is more than or equal to 6KPa, when the vacuum degree of the motor is less than 6KPa, and the air duct 2 is opened, the pressure difference formed between the sea and the sea 51 inside and outside is not enough to shake the sea handkerchief paper, and the effect is not good.

2. As shown in FIG. 4, the minimum cross-sectional area S2 of the air duct 2 is more than or equal to 600mm²(rectangle is A. about. B, ellipse is π. about. a. about. B, circle is π. r²) So as to form a better pressure difference between the inside and the outside of the HEPA 51.

3. As shown in FIG. 5, the opening area S1 pi d h is 900mm or more of the valve 1². The opening area of the valve 1 determines the upper limit of the air volume and pressure acting inside the hepa 51, and the larger the value, the better the beating effect.

4. As shown in the figures 6-7, the height C between the upper edge of the air inlet grid of the HEPA frame and the end surface of the HEPA frame is more than or equal to 7mm, the distance D between the air inlet grid of the HEPA frame and the motor opening is more than or equal to 20mm, C and D determine the air volume directly sucked away by the motor and the air volume acting on the interior of the HEPA, and the larger C and D are, the larger the pressure difference between the interior and the exterior of the HEPA is, the better the flapping.

In the description of the present application, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.
