Description

Technical Field

[0001] This utility model relates to the field of fresh air system technology, and in particular to an indoor air purification and ventilation device. Background Technology

[0002] Indoor air purification and ventilation are important measures to improve air quality and protect health. They are mainly divided into three categories: natural ventilation, mechanical ventilation, and air purification technology. Natural ventilation has the lowest cost, but areas with severe pollution need to rely on mechanical ventilation or purification equipment. Purification equipment is usually used in conjunction with mechanical ventilation, and filtration is undoubtedly the most widely used purification measure. Among the existing indoor purification equipment that combines mechanical ventilation and purification equipment, wall-mounted ventilation equipment is the most widely used. It purifies indoor air by drawing in outdoor air, aligning it for filtration and heating, and then introducing it into the room. However, due to the tight connection structure and complex layout of existing equipment, the innermost filter components are difficult to replace quickly. Long-term accumulation of dust will block the air duct and reduce the filtration quality. Therefore, this utility model improves the existing equipment to address the above problems.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-5 This utility model discloses an indoor air purification and ventilation device, comprising a housing 1, which is a semi-enclosed box structure with an opening at the back. A front panel assembly is located inside the housing 1, and a back panel assembly is connected and fixed to the housing 1 via the front panel assembly. The back panel assembly is vertically mounted and fixed to a wall 11. A filter assembly is horizontally positioned above the back of the back panel assembly. The wall 11 has through holes to accommodate the filter assembly. The modular design facilitates device maintenance and upgrades, improving practicality. The front panel assembly includes the housing 1, with an installation opening at the upper part of its front surface. A mounting plate is installed within the installation opening. A warning light strip 2 is provided, and the back of the warning light strip 2 is connected and fixed to the circuit board 3. The circuit board 3 is installed and fixed inside the back of the outer casing 1. An air outlet 4 is provided below the circuit board 3 on the top surface of the outer casing 1. An exhaust fan 14 is installed and fixed on the air outlet 4 on the front side of the fixing plate 7. An electric heating element 15 is provided a distance above the exhaust fan 14. The electric heating element 15 is installed and fixed on the fixing plate 7. The exhaust fan 14 and the electric heating element 15 are both connected to the circuit board 3 through wires. The circuit board 3 automatically coordinates all functional components to work together, which improves practicality.

[0020] In this utility model, to solve the problems of difficult disassembly and filter replacement in existing equipment, the following technical solution is adopted: The outer shell 1 has symmetrically arranged snap-fit ​​interfaces 6 on its left and right sides; the inner front face of the outer shell 1 is horizontally fixed with insertion sleeves 5, and the insertion sleeves 5 have pin holes inside; the back plate assembly includes a fixing plate 7; the front face of the fixing plate 7 is fixed with pin posts 8 at positions corresponding to the insertion sleeves 5; the front face of the fixing plate 7 is fixed with snap-fit ​​interfaces 6; the front face of the fixing plate 7 has evenly spaced through holes, and connecting bolts 10 are installed in the through holes; the connecting bolts 10 are screwed... The filter assembly, including a duct 12, is fixed to the wall 11. The duct 12 is fitted into a through hole in the wall 11. The front end of the duct 12 is connected to the fixing plate 7, and the other end of the duct 12 is fitted with a rain cover 13. The duct 12 has a filter element frame 16 inside. The filter element frame 16 is a cone-shaped support structure. The front end of the filter element frame 16 is fixed to the fixing plate 7.

[0021] Working Principle: When using this utility model, firstly, power is supplied to circuit board 3, then circuit board 3 will perform a self-test. The self-test structure is then displayed by indicator light bar 2. After the self-test is normal, the exhaust fan 14 is started to expel the air inside the device, creating a negative pressure environment inside the device, thereby allowing outdoor air to enter the device. The outdoor air first filters out dust through filter screen 17, then is heated and sterilized by heating element 15, and finally sent into the room through exhaust fan 14 from air outlet 4, filling the room with dust-free and sterile purified air. When the filter needs to be replaced, circuit board 3 controls indicator light bar 2 to prompt the personnel. After noticing the prompt, the personnel first press the buckle 9 fastened in the buckle interface 6 to disengage it from the buckle interface 6, then pull out the outer shell 1 to disengage the pin post 8 from the plug sleeve 5. Then the filter frame 16 installed and fixed on the fixing plate 7 can be seen. Then the filter frame 16 is removed and a clean filter screen 17 is replaced to restore the filtration and purification capacity of the device. Finally, the outer shell 1 is reinstalled to continue working.
