Description

Technical Field

[0001] This utility model relates to the field of purification equipment technology, specifically to an indoor environment purification device. Background Technology

[0002] After a building is renovated, it will generate a certain amount of indoor environmental pollution. Because paint and some building materials contain harmful gases, these gases mix in the air and enter the human body through the respiratory tract, causing various adverse effects on the human body. Therefore, it is necessary to treat the indoor air. The quality of the indoor environment is closely related to health. Here, let's first talk about the home environment that everyone comes into contact with.

[0003] Existing air purification equipment falls far short of expectations. Taking the living room as an example, even if the area is not very large, it is difficult to feel a significant freshness after the equipment has been running for a long time. When the room is large, the purification time will increase significantly, and the efficiency is difficult to meet daily needs. The HEPA filter that the equipment relies on can filter micron-sized particles, but its adsorption capacity for gaseous pollutants is very limited. The commonly used activated carbon filter is easily saturated and needs to be replaced frequently, which increases the cost of use and causes inconvenience in operation. When the room temperature rises or the equipment's fan speed changes, the saturated activated carbon filter may release pollutants again, making the previous purification efforts futile. Most environmental purification equipment uses a single purification technology or simply combines HEPA and activated carbon filters, which is insufficient to deal with the complex pollution problems in the home environment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes an indoor environmental purification device that significantly improves indoor air purification efficiency. It can cover different indoor areas, including large living rooms, and can quickly bring a noticeable sense of freshness after being turned on, avoiding the problem of excessively long purification time in large spaces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an indoor environmental purification device, comprising a purification box, universal wheels fixedly installed at the bottom of the purification box, a control plate fixedly installed on one side of the purification box, a preliminary composite filter slidably installed at the front end of the purification box, an exhaust fan fixedly installed at the bottom inside the purification box, diversion plates fixedly installed on both sides of the bottom inside the purification box, a limiting plate fixedly installed at the upper end of the diversion plates, the preliminary composite filter slidably connected to the limiting plate, a fixing block fixedly connected to the inner side wall of the purification box, an ultraviolet germicidal lamp fixedly connected to one side of the fixing block, a negative ion generator fixedly installed at the center inside the purification box, an exhaust fan fixedly installed at the upper end of the negative ion generator, a fixing frame fixedly installed at the bottom inside the purification box, a filter connecting frame slidably installed in the fixing frame, and an air outlet hopper fixedly installed at the upper end of the purification box.

[0007] Preferably, a handle is fixedly installed at the outer end of the preliminary composite filter.

[0008] Preferably, the front end of the purification box is provided with a sliding groove, the filter connecting frame is slidably connected to the sliding groove, and the filter connecting frame is magnetically connected to the fixing frame.

[0009] Preferably, the air outlet duct has a sound-absorbing compartment inside, and sound-absorbing cotton is fixedly installed in the inner ring of the air outlet duct. The air outlet duct has a horn-shaped structure, and the large-diameter end of the air outlet duct is fixedly connected to the upper end of the purification box.

[0010] Preferably, the diversion plate is inclined, and the inclined direction of the diversion plate is towards the exhaust fan.

[0011] Preferably, the ultraviolet germicidal lamps are provided in two sets, and both sets of ultraviolet germicidal lamps are located between the negative ion generator and the limiting plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1 - Figure 5 An indoor environmental purification device includes a purification box 1, with casters 2 fixedly installed at the bottom of the purification box 1, a control plate 3 fixedly installed on one side of the purification box 1, a preliminary composite filter 6 slidably installed at the front end of the purification box 1, an exhaust fan 16 fixedly installed at the bottom inside the purification box 1, and diversion plates 15 fixedly installed on both sides of the bottom inside the purification box 1. A limiting connecting plate 13 is fixedly installed at the upper end of the diversion plate 15, and the preliminary composite filter 6 is slidably connected to the limiting connecting plate 13. A fixing block 18 is fixedly connected to the inner side wall of the purification box 1, and an ultraviolet germicidal lamp 19 is fixedly connected to one side of the fixing block 18. A negative ion generator 11 is fixedly installed at the center inside the purification box 1, and an exhaust fan 12 is fixedly installed at the upper end of the negative ion generator 11. A fixing frame 9 is fixedly installed at the bottom inside the purification box 1, and a filter connecting frame 8 is slidably installed inside the fixing frame 9. An air outlet duct 5 is fixedly installed at the upper end of the purification box 1.

[0023] When in use, the device is turned on by controlling the connection plate 3. After the exhaust fan 16 starts, it generates negative pressure, drawing indoor air into the purification box 1. The inclined guide plate 15, facing the exhaust fan 16, can guide the air to quickly converge to the area of ​​the exhaust fan 16, avoiding air stagnation at the bottom of the purification box 1 and ensuring that the air enters the subsequent purification stage efficiently. If a lot of dust or hair is found on the surface of the filter, you can hold the handle 7 at the outer end of the filter and pull out the filter along the limiting connecting plate 13. Rinse it with clean water or use a vacuum cleaner to remove surface impurities, dry it, and then reinstall it. If the filter is damaged or the filtration effect is significantly reduced, a new filter needs to be replaced in time. If the first adsorption cotton 14 and the second adsorption cotton 17 are yellowed and clumped, the activated carbon filter 22 loses its ability to adsorb odors, and the surface of the photocatalyst layer 21 is dirty, you need to pull out the filter connecting frame 8, take out the old component and replace it with the corresponding new component. After replacement, push it back into its original position and ensure that it is magnetically fixed with the fixing frame 9. Wipe the outer shell of the purification box 1 and the control connection plate 3 with a dry cloth regularly to avoid dust accumulation affecting the heat dissipation of the equipment.

[0024] like Figure 5 As shown, the filter connecting frame 8 contains, in sequence, a first adsorbent cotton 14, a filter screen 10, an activated carbon filter screen 22, a photocatalyst layer 21, and a second adsorbent cotton 17. During the above-mentioned use, the air filtered by the preliminary composite filter screen 6 will continue to enter the filter connecting frame 8: the first adsorbent cotton 14 first further adsorbs fine dust particles in the air, then the filter screen 10 intercepts even smaller suspended particles, then the activated carbon filter screen 22 adsorbs odors and harmful gases in the air, and the photocatalyst layer 21, with the assistance of the subsequent ultraviolet germicidal lamp 19, can catalytically decompose residual harmful organic matter in the air. Finally, the second adsorbent cotton 17 filters the treated air again to ensure that impurities are completely removed and achieve multi-layer deep purification.

[0025] like Figure 1 As shown, a handle 7 is fixedly installed at the outer end of the preliminary composite filter screen 6. During the above-mentioned use, when the preliminary composite filter screen 6 accumulates a lot of impurities due to long-term use and the filtration efficiency decreases, the user can hold the handle 7 and pull the preliminary composite filter screen 6 outward along the sliding track of the limiting connecting plate 13 for cleaning or replacement. After cleaning and drying, the filter screen can be pushed back to its original position along the track using the handle 7. The operation is convenient and does not require the use of additional tools.

[0026] like Figure 1As shown, the front end of the purification box 1 has a sliding groove, the filter connecting frame 8 is slidably connected to the sliding groove, and the filter connecting frame 8 is magnetically connected to the fixing frame 9. During the above-mentioned use, when it is necessary to replace the filter component inside the filter connecting frame 8, the user can pull the filter connecting frame 8 outward so that it slides along the sliding groove and is removed from the magnetic attraction range of the fixing frame 9. After the replacement is completed, the filter connecting frame 8 is aligned with the sliding groove and pushed in until it is magnetically attached to the fixing frame 9 to achieve a stable installation. The whole process does not require disassembling the main body of the purification box 1, and the replacement efficiency is high.

[0027] like Figure 1 or Figure 3 As shown, a sound-absorbing compartment 20 is provided inside the air outlet 5, and sound-absorbing cotton 4 is fixedly installed in the inner ring of the air outlet 5. The air outlet 5 has a horn-shaped structure, and the large-diameter end of the air outlet 5 is fixedly connected to the upper end of the purification box 1. During the above-mentioned use, the clean air that has undergone multi-layer purification and negative ion treatment will be transported upward to the air outlet 5 under the action of the suction fan 12. The sound-absorbing compartment 20 can reduce the noise generated by air flow, and the sound-absorbing cotton 4 further absorbs high-frequency noise, achieving low-noise air outlet. The horn-shaped structure receives air through the large-diameter end and outputs it through the small-diameter end, making the air diffusion range wider and the air outlet more uniform, ensuring that clean air quickly covers the indoor space.

[0028] like Figure 2 or Figure 3 As shown, the diversion plate 15 is set at an angle, and the angle of the diversion plate 15 is towards the exhaust fan 16. In the above-mentioned use, in addition to guiding the air to converge, it can also prevent the accumulation of a small amount of condensate or impurities that may be generated during the purification process at the bottom of the purification box 1. The inclined structure allows the condensate or impurities to flow along the plate towards the discharge area near the exhaust fan 16 (if the equipment has a related structure), reducing the corrosion of the internal components of the purification box 1 and extending the service life of the equipment.

[0029] like Figure 3 As shown, there are two sets of ultraviolet germicidal lamps 19, and both sets of ultraviolet germicidal lamps 19 are located between the negative ion generator 11 and the limiting plate 13. During the above-mentioned use, the air that has been preliminarily filtered will flow through the area of ​​the ultraviolet germicidal lamps 19. When the two sets of ultraviolet germicidal lamps 19 are turned on at the same time, they can release sufficient ultraviolet light to kill bacteria, viruses, mold spores and other microorganisms in the air. The coverage is wider and the sterilization is more thorough. Because it is located in front of the negative ion generator 11, it can ensure that the air entering the negative ion generator 11 has been sterilized, avoid the combination of microorganisms and negative ions affecting the purification effect, and prevent microorganisms from spreading into the room with the negative ions.

[0030] like Figure 1 or Figure 3As shown, the exhaust fan 16, negative ion generator 11, ultraviolet germicidal lamp 19, and suction fan 12 are all electrically connected to the control board 3. During the above-mentioned use, the control board 3 can also adjust the speed of the exhaust fan 16 and suction fan 12, and control the start and stop time of the ultraviolet germicidal lamp 19 to meet the usage needs of different indoor environments such as low noise in the bedroom and strong purification in the living room. The operation is intuitive and convenient.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
