Description

Technical Field

[0001] The present invention relates to the technical field of fresh air filtering, and in particular to a self-cleaning fresh air filtering device for seven-heng buildings. Background Art

[0002] A fresh air filter is a device used to improve indoor air quality. It is usually installed in the ventilation system of a building. Its main function is to filter the external air entering the room and remove harmful substances such as particulate matter, bacteria, viruses, pollen, dust, odor, etc., thereby providing cleaner and healthier indoor air. However, the filter in the existing filter device cannot be cleaned automatically and needs to be manually removed for cleaning, which is time-consuming and labor-intensive. In addition, if the filter is not cleaned in time, it is easy to be clogged by dust, resulting in reduced filtering effect.

[0003] The patent with patent number CN202111623516.8 discloses an energy-saving fresh air unit and its purification and filtering device. The cleaning brush of the patent can clean the inner wall of the air inlet pipe and the air outlet pipe installed indoors, thereby reducing the dust inside the fresh air unit when in use, and through the rotation of the inner barrel inside the outer barrel, it is easier to self-clean the dust on the cleaning brush. The dust on the cleaning brush can also be collected and processed by the storage box, thereby improving the self-cleaning and filtering effect of the overall device. The first scraper and the second scraper can clean the dust on the filter net, as well as the first filter plate and the second filter plate. The cleaning process is carried out, and the first dust box and the second dust box are driven to rise and fall by the second electric hydraulic rod inside the sliding frame, so that the dust scraped by the first scraper and the second scraper can be collected and processed by the first dust box and the second dust box respectively, thereby improving the use effect and filtering effect of the filter. Although this patent solves the above problems, the scraper can only clean the dust on the surface of the filter, and cannot automatically clean the dust in the micropores inside the filter, and frequent friction can easily cause damage to the filter plate structure, thereby reducing the filtering effect. Therefore, a self-cleaning fresh air filter device for Qiheng Building is proposed to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a self-cleaning fresh air filtering device for seven-heng buildings in view of the deficiencies in the above-mentioned prior art.

Open the sliding door and insert the filter element into the positioning slide rail to fix it. When the filter element needs to be cleaned, just pull it out from the positioning slide rail and start the motor. The motor drives the eccentric shaft one, the transmission shaft and the eccentric shaft two to rotate. The eccentric shaft one and the eccentric shaft two drive the slide frame to move back and forth left and right. The slide frame drives the connecting rod and the center slide rod to move back and forth left and right. The center slide rod drives the splint to move back and forth. When the splint moves, it squeezes the spring to generate vibration, which drives the filter element to vibrate, shakes off the impurities, and drops them out from the limiting slide and the notch opened on the bottom of the filter box.

When the side sliding rod slides to the left, it drives the push rod to move to the left, and the push rod drives the paddle plate to deflect, and the paddle plate drives the water spraying tube to deflect. When the push plate moves to the right, the torsion spring drives the water spraying tube to reset, thereby driving the water spraying tube to swing when the push rod moves back and forth left and right.

After absorbing impurities, water falls to the bottom of the filter box, and then flows into the drainage box through the water outlet inclined frame. The one-way valve in the drain pipe can be opened to discharge the water with impurities. At the same time, the impurities shaken off the filter element fall onto the partition in the drainage box through the groove on the positioning slide rail. The partition isolates some impurities from the water. When the push rod moves back and forth left and right, it drives the L-shaped push rod and the push plate to move back and forth left and right, and the push plate pushes the impurities deep in the partition to the door panel.

[0008] The present invention adopts the above technical solution to bring the following beneficial effects:

[0009] 1. The self-cleaning fresh air filter device for Qiheng Building inserts the filter element into the positioning slide rail for fixing. When the filter element needs to be cleaned, the filter element can be pulled out from the positioning slide rail. It is convenient and quick. When the splint moves, the spring is squeezed to generate vibration, which drives the filter element to vibrate, and the impurities are shaken off and fall out from the limiting slide groove and the grooves on the bottom of the filter box. In this way, some impurities can be automatically removed from the filter element without manual cleaning, which prevents the filter element from being blocked due to excessive accumulation of impurities and improves the filtering efficiency.

[0010] 2. In the self-cleaning fresh air filtration device for Qiheng buildings, water flows out from the water outlet trough and contacts the wind entering the filter box, adsorbs impurities that are not filtered out, and then flows into the bottom of the filter box, improving the filtering effect of the device. The reagent flows from the slot to the right side of the partition and mixes with the water, enhancing the adsorption of water and improving the adsorption effect. Water is sprayed into the filter box through the nozzle arranged on the water spray circular pipe, increasing the adsorption area. The water spray circular pipe swings, increasing the spraying area, further increasing the adsorption area, thereby promoting the adsorption efficiency.

[0011] 3. The self-cleaning Qiheng building fresh air filter device can discharge water with impurities by opening the one-way valve in the drain pipe, thereby automatically discharging the impurities. It is convenient and quick. The partition separates some impurities from water to avoid excessive impurities adhering to the water, which is convenient for subsequent recycling and improves practicality. The push plate pushes the impurities deep in the partition to the door panel, thereby concentrating the impurities and making it convenient for staff to remove the impurities.
