Description

Technical Field

[0001] The invention relates to the technical field of air sterilizers, in particular to a high-efficiency and energy-saving air sterilizer. Background Art

[0002] An air sterilizer is a device used to eliminate or kill bacteria, viruses, molds and other microorganisms in the air. It is widely used in hospitals, schools, offices and other places. Its main function is to purify and disinfect the air through physical or chemical methods, thereby improving indoor air quality and reducing the risk of infection. Among them, a plasma air sterilizer is a device that uses plasma technology to purify and disinfect the air. Its working principle is mainly to generate plasma through high-voltage discharge, releasing high-energy electrons, ions and free radicals. These active substances can destroy the cell membranes of microorganisms such as bacteria, viruses and fungi, thereby achieving a sterilization effect. At the same time, plasma can also decompose harmful gases and odors in the air, such as formaldehyde, benzene, TVOC, etc., thereby improving indoor air quality. Plasma air sterilizer has many advantages, including high-efficiency sterilization ability, environmental protection, low energy consumption and long service life.

[0003] In the prior art, after the air sterilizer has been running for a long time, the filter will accumulate a lot of dust, bacteria and other contaminants, and the filter must be cleaned or replaced regularly. However, this process usually requires manual disassembly and replacement of the filter, which not only consumes time and energy, but also increases maintenance costs. Improper operation may also cause equipment damage or human contamination. Therefore, this traditional manual replacement method has defects in convenience and hygiene. Especially when the air sterilizer needs to be operated frequently, the frequency and tediousness of manual operation make the maintenance efficiency of the equipment low, and also increase the labor intensity of the user. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide a high-efficiency and energy-saving air sterilizer to solve the technical problem that the air sterilizer requires manual disassembly and replacement of the filter, which is cumbersome and inefficient to operate and difficult to meet the needs of frequent maintenance and efficient operation.

[0008] By adopting the above technical solution, the cleaning assembly is driven by the rotation of the blower, and the brush on the scraper rod can clean the filter surface in real time to avoid dust and impurities accumulation, thereby extending the service life of the filter, reducing the frequency of manual maintenance, and improving the automation of the equipment. At the same time, the design of the filter cleaning assembly enables the equipment to maintain a stable purification efficiency during long-term operation, thereby reducing the operating cost. In terms of filter replacement, the automatic release of the old filter and the precise installation of the new filter are achieved through the cooperation of the one-way shaft and the reciprocating thread. The filter to be replaced is pushed from the placement chamber to the specified position, and the old filter slides into the recovery chamber under the action of gravity. The filter is prevented from being stuck by the angled structure designed in the recovery chamber. The entire replacement process does not require manual intervention and can be completed by sending instructions through the control panel. It is convenient and efficient, and greatly reduces the manual operation cost caused by frequent filter replacement. In addition, during the filter replacement process, an infrared sensor is used for detection to ensure that the new filter is accurately positioned each time it is pushed. At the same time, the partition design of the recovery chamber and the placement chamber is reasonable, which is convenient for operators to centrally process the old filter or replace the new filter, further improving the environmental protection performance of the equipment and user experience.

[0056] The working principle of the present invention is as follows: when in use, after the power is turned on, the air sterilizer starts, and the suction force generated by the blower 501 sucks the gas into the casing 1, and the gas passes through the high-efficiency filter layer 1401, the photocatalyst filter layer 1402 and the nano silver activated carbon filter layer 1403 in sequence. These three layers of filter screens are coordinated in multiple stages to efficiently filter and adsorb particulate matter, harmful substances and bacteria and viruses in the gas, thereby significantly improving the effect and efficiency of air purification;

At this time, the inner ring of the one-way shaft 504 drives the outer ring to rotate synchronously, and the reciprocating thread 505 on the surface of the outer ring pushes the moving block 506 to move back and forth on the one-way shaft 504. The moving block 506 drives the integrated filter 14 to unlock through the connecting rod 507 and the push rod 509. The old filter slides into the recovery chamber 6 under the action of gravity. The recovery chamber 6 is provided with an inclined surface design to prevent the filter from being stuck at the entrance. The filter to be replaced falls into the working area from the placement chamber 7, and cooperates with the fixing groove 1404 through the bevel at the bottom, and is accurately positioned by the push rod 509 to complete the replacement operation, thereby ensuring the stability and sealing of the new filter.

[0059] To ensure timely replacement of the filter, the operator can open the placement chamber 7 through the first cover plate 23 and place multiple sets of filters to be replaced. The electric push rod 401 arranged in the placement chamber 7 will push the new filter to the replacement area at a regular time according to the detection of the infrared sensor 22, avoiding the inconvenience of manual operation. When the old filter accumulated in the recovery chamber 6 needs to be processed, the operator can open the second cover plate 24 to centrally clean and process the filter in the recovery chamber 6. The entire system design realizes the automatic cleaning and automatic replacement functions of the filter, improves the utilization efficiency and intelligence level of the equipment, and effectively reduces the frequency and difficulty of manual maintenance. It is convenient, efficient, energy-saving and environmentally friendly.
