Description

Filter component for vacuum cleaner

Technical Field

The utility model belongs to the technical field of vacuum cleaners, and more specifically, particularly relates to a filter component for a vacuum cleaner.

Background Art

The working principle of a vacuum cleaner is that the vacuum cleaner motor rotates at high speed, sucking air into the air inlet, making the inside of the dust box vacuum, sucking dust into the dust box, and the dust is discharged from the exhaust port after filtering. To ensure the filtering effect, a filter element and a filter cover are often used in combination for double-layer filtration.

When the existing filter element and filter cover are assembled for filtering, larger dust and debris are concentrated on the outside of the filter cover and inside the dust box. When cleaning the dust inside the dust box, it is difficult to completely scrape out entangled objects such as hair. In addition, the dust is relatively light. When cleaning the dust box, it is difficult to squeeze the dust out and clean it all at once by pushing it out with a push plate.

Embodiment 1:

As shown in Figures 1 to 7:

The utility model provides a filter component for a vacuum cleaner, comprising a main component 1, a connecting component 2, a dust box 3 and a filter core 4; a vacuum cleaner is arranged inside the main component 1, an exhaust port is provided on the rear outer wall of the main component 1, and the bottom of the main component 1 is connected to the top of the connecting component 2; the bottom of the connecting component 2 is connected to the top of the dust box 3, and a filter cover 5 is installed inside the connecting component 2; the filter core 4 is installed inside the filter cover 5; a buckle cover 301 is movably connected to the bottom of the dust box 3 through an axis, and a slideway 302 is arranged on the right side of the dust box 3; a push plate 6 is slidably engaged with the inside of the slideway 302, and an auxiliary block 7 is interference engaged with the lower part of the slideway 302; a scraper ring 601 is integrally formed on the inner side of the push plate 6, and a push rod 602 is arranged at the bottom of the push plate 6; a limiting hole 702 is arranged inside the auxiliary block 7.

As shown in Figures 4 and 6, a clamping block 701 is provided at the right end of the auxiliary block 7. The clamping block 701 protrudes from the right end surface of the slideway 302. The interior of the limiting hole 702 is penetrated by the push rod 602. When the push rod 602 moves downward, the limiting hole 702 can limit and support the bottom of the push rod 602 to avoid bending or breaking of the push rod 602 when the buckle cover 301 is pushed open. When the push rod 602 moves upward, the limiting hole 702 limits the blocking piece 6021, so that the push plate 6 has the maximum upward movement distance.

As shown in Figures 2 and 3, a threaded groove is opened on the top outer wall of the filter core 4, and the filter core 4 is fixedly connected to the bottom of the main unit 1 by threaded engagement. The filter core 4 and the main unit 1 are fixedly connected by threaded engagement, which plays a filtering role and makes the filter core 4 removable and replaceable.

As shown in Figures 3 and 5, the inner wall of the scraper ring 601 is attached to the outer wall of the filter cover 5, and the outer wall of the scraper ring 601 is attached to the inner wall of the dust box 3. The height of the push rod 602 is less than the height of the dust box 3, and the bottom end of the push rod 602 is provided with a baffle 6021, and the outer diameter of the baffle 6021 is greater than the aperture size of the limiting hole 702. When the push plate 6 is pulled downward, the push rod 602 is simultaneously driven downward. When the push rod 602 moves downward to the inside of the slide groove 3011, the scraper ring 601 seals the outside of the filter cover 5 and the dust box 3. The dust and debris inside the dust box 3 are scraped and squeezed, and the push plate 6 is pushed downward continuously, and the push rod 602 pushes the buckle cover 301 while sliding in the slide groove 3011, and the scraper ring 601 pushes the dust and debris inside the dust box 3 outward, and the hair and other debris outside the filter cover 5 can be completely removed. When the push plate 6 is pushed to the top surface of the auxiliary block 7, the movement of the push plate 6 can be stopped by the collision between the push plate 6 and the auxiliary block 7. At the same time, due to the action of inertia, the debris and dust continue to move downward, and the dust inside the dust box 3 is cleaned.

As shown in Figure 2, an annular structure clamping plate is provided on the top of the connecting member 2, the cross-section of the clamping plate is a right-angle structure, and the clamping plate is fixedly clamped on the inner bottom end of the main unit 1. An annular plate is provided on the bottom of the connecting member 2, and the annular plate is interference fit and plugged into the top of the dust box 3. The connecting member 2 can be used to assemble and connect the main unit 1 and the dust box 3 to form an integrated structure for dust collection and filtering.

As shown in Figure 4, small filtering holes are opened inside the filter cover 5, and the top outer wall of the filter cover 5 is fixedly connected to the inner lower side of the connecting piece 2 by threaded engagement, and the height of the filter cover 5 is lower than the height of the dust box 3. When the vacuum cleaner sucks air and dust into the dust box 3 through the air suction pipe, preliminary filtration is performed through the filter cover 5 to block larger dust and debris into the dust box 3 and the outside of the filter cover 5, thereby reducing the filtration load of the filter element 4, protecting the filter element 4, preventing larger debris or particles from damaging the filter element 4, and making the filter cover 5 easy to disassemble and clean.

As shown in Figure 7, a slide groove 3011 is opened on the right side of the top surface of the buckle cover 301, the right end of the slide groove 3011 is in an open state, and the slide groove 3011 is located below the push rod 602. When the push rod 602 moves down, it is inserted into the slide groove 3011. As the push rod 602 continues to move downward, it slides inside the slide groove 3011 and pushes the buckle cover 301 to rotate, thereby realizing automatic opening so as to dump the dust inside the dust box 3.

The specific usage and function of this embodiment are as follows:

In the present invention, the filter element 4 is first installed on the upper inner side of the connecting member 2, and then the filter cover 5 is installed on the lower inner side of the connecting member 2, and then the connecting member 2 is connected to the bottom of the main body 1, and finally the connecting member 2 is connected to the top of the dust box 3 by interference fit to complete the assembly;

After vacuuming through the main unit 1, larger dust and debris are filtered to the outside of the dust box 3 through the filter cover 5, and smaller dust is filtered through the filter element 4. When cleaning the dust inside the dust box 3, first remove the dust suction connecting pipe, then push the push plate 6 downward, and simultaneously drive the scraper ring 601 to compress the dust inside the dust box 3 to make it dense and solid, then continue to move the push plate 6 downward so that the push rod 602 is inserted into the slide groove 3011 to push the buckle cover 301 open, and the dust is discharged outward to complete the cleaning.

Embodiment 2, on the basis of embodiment 1, the connecting member 2 can also be replaced with a threaded engagement connection structure, the upper part of the connecting member 2 is fixedly connected to the bottom of the main component 1 by threaded engagement, and the lower part of the connecting member 2 is fixedly connected to the dust box 3 by threaded engagement. The connection method of the connecting member 2 can be selected and adapted according to the size of the vacuum cleaner and the size of the dust box 3, so that the dust box 3, the filter element 4, and the filter cover 5 can be assembled, and it is also convenient to disassemble for cleaning or replacement.
