Description

Auto-cleaning filter screen

Technical field

The utility model belongs to field of household appliances, relates in particular to a kind of auto-cleaning filter screen.

Background technology

Screen pack is a large amount of applies to household electric appliances, be used for air is filtered, as landing in the air-conditioner split type, need screen pack to be set at the air inlet place, screen pack is the meeting laying dust after use a period of time, cause that the mesh obstruction causes ventilation not smooth, the cleaning mode of present most of screen pack all is to adopt by hand to pull down filtering net cleaning, and the user cleans inconvenience.

Summary of the invention

The object of the present invention is to provide a kind of cleaning screen pack more easily.

The utility model is achieved by the following technical solution:

A kind of auto-cleaning filter screen, comprise at least two screen holders, be equipped with filter screen and dust brush on it, the filter screen of dust brush on another screen holder on one of them screen holder, under the effect of transmission mechanism, one of them screen holder can slide with respect to another screen holder; One end of sweep-up pipe is communicated with dust exhaust apparatus, and the other end is provided with suction port, and this suction port is near filter screen.

In the utility model, in the time of need cleaning filter screen, open transmission mechanism, one of them screen holder slides with respect to another screen holder, dust brush on one of them screen holder cleans the filter screen on another screen holder, dust exhaust apparatus siphons away the dust on the filter screen, and in terms of existing technologies, the cleaning of filter screen described in the utility model is more convenient; During the cleaning dust, a plurality of dust brushes are worked simultaneously, and cleaning efficiency is higher.

Further improvement of the utility model is:

Described screen holder is two, and the distance of these two screen holders two sides farthest are the open type groove, and the open type groove is provided with port and strip opening, and is corresponding, and described dust brush is bar shaped; In two relative sliding processes of screen holder, the port on the open type groove can be relative with described suction port.Adopt the dust brush of bar shaped, dedusting face is big, good dedusting effect, and the dust under the dust brush removes can be collected in the strip opening of open type groove, and enters in the dust exhaust apparatus through open type groove port, suction port.

Described two bar shaped dusts brush is perpendicular to the glide direction of screen holder, and described dust brush is located on its place screen holder near another described screen holder one side.Promptly two dusts brush is located at the lower side position of upper sieve frame and the upper side edge position of bottom screen holder respectively, and what this structure can make the dust brush cleans the area maximum with water, avoids leaving the dead angle.

The upper side edge of the superposed described screen holder of one of them described open type groove, another described open type groove is positioned at the lower side of the described screen holder of bottom; Described sweep-up pipe is located on the vertical side of described filter screen.When the cleaning filter screen, dust can fall under the gravity effect, the open type groove is located on the upper and lower side of screen holder, and the effect of collecting dust is better.

A screen holder is provided with chute therein, and another screen holder places in this chute and can slide relatively; And the side on one of them screen holder is provided with tooth bar, and another screen holder is provided with the gear that matches with this tooth bar, and gear is connected with motor output shaft by gear shaft, and described transmission device is this tooth bar, gear, gear shaft, motor.During the cleaning dust, open motor, gear rotation under gear shaft drives, gear drives tooth bar again and screen holder slides up and down, and the dust on the filter screen is cleaned.

Described tooth bar is two, two relative sides of a difference described screen holder located therein, and corresponding, described gear is two, is located at two relative sides of another described screen holder respectively.Gear, rack drives screen holder by two relative sides slide, and be more reliable, steady when screen holder slides.

The specific embodiment

Extremely shown in Figure 6 as Fig. 1, a kind of auto-cleaning filter screen, comprise two screen holders 1, be equipped with filter screen 2 and dust brush 3 on it, the filter screen 2 of dust brush 3 on another screen holder 1 on one of them screen holder 1, under the effect of transmission mechanism, one of them screen holder 1 can slide with respect to another screen holder 1; One end of sweep-up pipe 4 is communicated with dust exhaust apparatus 5, and the other end is provided with suction port 6, and this suction port 6 is near filter screen 2.

Wherein, bottom screen holder 1 is a fixed mount, upper sieve frame 1 is a travelling carriage, the lower side of the upper side edge of the screen holder 1 on top, the screen holder 1 of bottom respectively is provided with an open type groove 7, sweep-up pipe 4 is located on the vertical side of filter screen, and open type groove 7 is provided with port 8 and strip opening 9, and is corresponding, two dusts brush 3 is for bar shaped and perpendicular to the glide direction of screen holder 1, two dusts brushes 3 are located at the lower side position of upper sieve frame 1 and the upper side edge position of bottom screen holder 1 respectively; In two screen holders, 1 relative sliding process, the port 8 on the open type groove 7 can be relative with suction port 6; A screen holder 1 is provided with chute 10 therein, and another screen holder 1 places in this chute 10 and can slide relatively; And two vertical sides on one of them screen holder 1 respectively are provided with tooth bar 11, the both sides of another screen holder 1 respectively are provided with a gear 12 that matches with tooth bar 11, gear 12 is connected with motor 14 output shafts by gear shaft 13, and transmission device is this tooth bar 11, gear 12, gear shaft 13, motor 14.
