[0002] An air purifier, also known as an "air cleaner," is a product that can absorb, decompose or transform various air pollutants to effectively improve air cleanliness. It is mainly used to solve indoor air pollution problems caused by decoration pollution such as dust, pollen, odor, formaldehyde, bacteria, allergens, etc.

[0003] The main functions of common air purifiers at present are to filter dust, eliminate bacteria, filter formaldehyde, etc. Most of them use high temperature sterilization, disinfectant sterilization or ultraviolet sterilization. When using ultraviolet sterilization, early products use UV lamps to directly irradiate and sterilize, and later changed to UV lamps irradiating photocatalysts to sterilize. When using photocatalysts to sterilize, the sterilization efficiency is high and the function is simple to implement, so it is adopted by many air purifier manufacturers.

[0004] Currently, most air purifiers on the market purify air through internal activated carbon filters. However, the air cannot be effectively purified through the filter alone, and the purification quality is not high. In addition, the grille plates are mostly fixed and installed by multiple bolts. When the internal part of the air purifier is damaged and needs to be repaired, the staff needs to manually turn the knobs of multiple bolts to disassemble it for repair, which not only consumes manpower, but also has slow maintenance efficiency, affecting the use effect.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 5 The utility model provides a technical solution: a UV photocatalyst air purifier, comprising an air purifier body 1, a side wall of the air purifier body 1 is provided with a detachable grid plate 4, a centrifugal fan 5 is installed on the top of the air purifier body 1, an isolation plate 6 is installed inside the air purifier body 1, UV lamp beads 7 are installed on the side walls of the isolation plate 6, and installation grooves 8 are opened on the side walls of the isolation plate 6, and a detachable photocatalyst filter element 9 is arranged in the installation groove 8.

[0031] Dual centrifugal fans 5 are provided to increase the pressure of the incoming air, and the grid plates 4 on both sides allow the air to enter from both sides, thereby accelerating the air intake rate.

[0032] It should be noted that the UV lamp beads 7 are symmetrically arranged on the surface of the isolation plate 6, and the UV lamp beads 7 form a photocatalyst excitation light source. The photocatalyst light source is matched with a photocatalyst filter element 9, and is matched with an air circulation fan and dual-channel vents on both sides to form an air duct, so that the gas in the air has enough time and conditions to fully contact with the photocatalyst filter element 9, thereby improving the quality of purification.

[0033] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a fixing block 2 is fixed to the side wall of the air purifier body 1, a support rod 3 is fixed inside the fixing block 2, and a grid plate 4 is rotatably sleeved with the support rod 3.

[0034] After long-term use, the air purifier body 1 may have internal faults, so it needs to be disassembled for inspection and repair. The grille plate 4 is disassembled to expose the inside of the air purifier for easy inspection and repair.

[0035] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an embedded block 41 is embedded inside the grid plate 4, and a rotating rod 42 is rotatably connected to the surface of the embedded block 41. A driving bevel gear 43 is fixedly sleeved on the end of the rotating rod 42, and driven bevel gears 44 are meshed at both ends of the driving bevel gear 43. A screw rod 45 is fixed in the middle of the driven bevel gear 44, and an insert rod 46 is sleeved on the external thread of the screw rod 45.

[0036] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the screw rod 45 is rotatably connected to the embedded block 41 , and a slot for plugging with the plug rod 46 is provided inside the air purifier body 1 .

[0037] It should be noted that there are two screw rods 45 , and the threads on the surfaces of the two screw rods 45 are arranged oppositely, so that the two insertion rods 46 can slide inward or outward at the same time.

[0038] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a groove 91 is provided inside the isolation plate 6 , a spring 92 is fixed to the inner wall of the groove 91 , a sliding rod 93 is fixed to the end of the spring 92 , a control rod 94 is fixed to the top of the sliding rod 93 , and a limiting rod 95 is fixed to the end side of the sliding rod 93 .

[0039] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, both sides of the photocatalyst filter element 9 are provided with limiting grooves for facilitating the clamping of the limiting rod 95 , and the surface of the isolation plate 6 is provided with an annular groove for facilitating the horizontal sliding of the control rod 94 .

[0040] It should be noted that a control terminal is provided on the top of the air purifier, and a display screen of air purification values ​​is provided on the surface. The control terminal transmits a signal to the UV lamp beads 7 and the display screen to start the air purifier, and the air purifier is turned on and used. The technical solution belongs to the existing technology in this field. The specific model specifications to be adopted need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0041] The use method and advantages of the utility model: When the UV photocatalyst air purifier is working, the working process is as follows:

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the air purifier is used to purify formaldehyde gas in the air, the purifier is turned on by the control end, and the UV lamp beads 7 are immediately turned on to form a photocatalyst excitation light source. The photocatalyst light source is matched with the photocatalyst filter element 9, and the centrifugal fan 5 is used to pressurize the air intake. At the same time, the air intake is double-channel, so that the gas in the air has enough time and conditions to fully contact with the photocatalyst filter element 9, thereby quickly completing the purification effect and improving the quality of purification;

[0043] The photocatalyst filter element 9 needs to be replaced for long-term use. When replacing, first rotate the rotating rod 42 to drive the active bevel gear 43 to rotate. When the active bevel gear 43 rotates, the driven bevel gears 44 at both ends rotate immediately and drive the middle screw rod 45 to rotate, and the plug rod 46 of the external threaded sleeve of the screw rod 45 slides inward immediately, so that the plug rod 46 is embedded in the grid plate 4 and disengaged from the air purifier body 1, and then the grid plate 4 is turned over and rotated around the support rod 3, so that the interior of the air purifier body is exposed, and then the control rod 94 is manually pressed to slide horizontally along the annular groove. When the control rod 94 slides, the sliding rod 93 at the bottom immediately drives the limiting rod 95 to slide into the groove 91 of the isolation plate 6 and squeeze the spring 92, so that the limiting rod 95 is separated from the photocatalyst filter element 9, so that the photocatalyst filter element 9 is quickly disassembled and then replaced. At the same time, the interior of the air purifier body 1 can be quickly inspected and repaired, thereby improving the inspection efficiency.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments.
