Technical Field

[0001] The utility model relates to the technical field of fresh air systems, in particular to a filter layer flushing structure and a fresh air system. Background Art

[0002] The central air conditioning fresh air system draws outdoor air into the machine, filters it, and blows it into the room. At the same time, it draws the dirty air in the room out to the outside, thereby gradually replacing the indoor air with fresh and healthy air. The working principle of this fresh air system to purify the air is physical filtration, that is, using filters to filter out harmful substances.

[0003] The filters used in the fresh air fan can be divided into primary filters and secondary filters according to their functions. The primary filters are mainly used to filter coarse particles such as hair and catkins and can be washed with water, while the secondary filters include HEPA filters and activated carbon filters, which are used to filter PM2.5 and viruses, bacteria and heavy metal particles attached to PM2.5, remove harmful gases in the inhaled air and absorb odors. However, the above two types of secondary filters cannot be washed with water, that is, washing with water cannot restore the use loss of the secondary filters. Therefore, in the prior art, only the primary filters can be washed with water, and the secondary filters can only be replaced as consumables.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a filter layer flushing structure and a fresh air system are proposed. Utility Model Content

[0009] Furthermore, a primary grille is fixed to the outer side of the air inlet by screws, and a boss is provided at the bottom end of the inclined surface of the air inlet.

[0010] Furthermore, two disassembly and assembly components are provided at the outlet end of the ventilation duct, and the disassembly and assembly components include a slot and a magnetic limit plate.

The advantage of this design is that there is no need to remove the primary grille 4 for cleaning. It is only necessary to pressurize the water flowing out of the water outlet pipe 102 at the output end of the water pump 101 and spray it from the atomizing nozzle array 103 to flush the primary grille 4. Under the action of gravity and the limiting action of the boss 5, the flushing water flow will naturally fall into the water pocket plate 109, and further flow into the water storage box 106 through the inlet 108. By arranging a filter plate 107 in the middle of the water storage box 106, the clean water is returned to the water pump 101 through the water inlet pipe 104 to realize a closed loop, so that the primary grille 4 can be automatically flushed and cleaned, and the frequency of refilling can be reduced by recycling the cleaning liquid, which has stronger applicability.

[0023] like Figure 1 to Figure 2 As shown, a fresh air system is installed with a filter layer flushing structure, including a ventilation pipe 2, the ventilation pipe 2 is a right-angled trapezoidal structure with an inclined inlet end, and an air inlet 3 is opened at the inlet end of the ventilation pipe 2, a primary grille 4 is fixed to the outside of the air inlet 3 by screws, and a boss 5 is arranged at the bottom of the inclined surface of the air inlet 3, and two disassembly assemblies 6 are arranged at the outlet end of the ventilation pipe 2, and the disassembly assemblies 6 include a slot 601 and a magnetic stop plate 602, the two slots 601 are arranged in parallel at the bottom of the rear end of the ventilation pipe 2, and the top of the slot 601 corresponds to a magnetic stop plate 602 fixed to the ventilation pipe. 2.

It is only necessary to pressurize the water flowing out of the water outlet pipe 102 at the output end of the water pump 101 and spray it from the atomizing nozzle array 103 to flush the primary grille 4. Under the action of gravity and the limiting action of the boss 5, the flushing water flow will naturally fall into the water pocket plate 109, and further flow into the water storage box 106 through the inlet 108. By setting a filter plate 107 in the middle of the water storage box 106, the clean water will flow back to the water pump 101 through the water inlet pipe 104 again. A closed loop is realized in the process, and automatic flushing and cleaning of the primary grille 4 is achieved.
