Description

Technical Field

[0001] The invention relates to the field of air purification, and in particular to an air purification device. Background Art

[0002] With the development of industrialization, air pollution is becoming more and more serious. The harmful substances mixed in the air seriously endanger the health of the general public. Due to the need for health, the use of air purification devices is becoming more and more common. Air purification devices can effectively filter harmful substances such as dust, bacteria, viruses, anti-allergens, formaldehyde, etc. in the air, and deliver the filtered safe air to ensure human health. Among them, dust removal is very critical. In the prior art, dust in the air is often filtered by setting a dust filter. This dust filtering method has the following disadvantages: 1) Since the distribution of dust in the air sucked into the air purification device is often uneven, the amount of dust gathered in each place on the dust filter will increase. In some areas, a large amount of dust will accumulate, and then the dust filter will be blocked, which will eventually lead to low filtering efficiency; 2) The dust filter can only generally intercept and filter dust below a certain size, and cannot filter in layers, which leads to the need for frequent replacement or cleaning of the dust filter; 3) It is extremely inconvenient to replace and clean the dust filter.

[0003] For example, the patent with application number CN202020864871.9 discloses an air purification device, and the filter in the air purification device has the above-mentioned disadvantages. The patent with application number CN202020159584.8 discloses an environmentally friendly air purification device, which removes dust on the filter in the following way: the output shaft of the motor drives the semicircular rotating block to rotate, and each time the semicircular rotating block rotates to the right half, the filter will be squeezed to the right through the filter dust removal baffle. When the semicircular rotating block rotates to the left half, the filter will rebound to its original position under the action of the spring, and this process will be repeated to achieve the effect of shaking off the dust accumulated on the surface of the filter. Although this method can achieve a certain cleaning effect, the effect is poor and the dust that is shaken off will still be sucked onto the filter by the exhaust fan.

[0004] Therefore, an air purification device that can solve the above problems is urgently needed. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies of the prior art, the present invention aims to provide an air purification device, which solves the problems existing in the prior art. The air entering the air purification device is fully mixed by setting a first mixing plate and a second mixing plate.

After the initial mixing, the dust in the air will be evenly distributed on the dust removal mechanism, and will not cause a rapid local blockage. The dust in the air can be filtered step by step through the dust removal mechanism, and the filtering effect is good. The dust removal mechanism is very convenient to clean and replace. The nano-silver antibacterial gel filter is set to have the effect of killing bacteria and viruses. The photocatalyst filter is set to eliminate harmful substances such as formaldehyde and benzene.

[0016] (III) Beneficial effects

[0017] 1. The present invention fully mixes the air entering the air purification device through the arrangement of the first mixing plate and the second mixing plate. After the air in the air purification device is fully mixed by the first mixing plate and the second mixing plate, the dust is fully filtered after passing through the dust removal mechanism. After the initial mixing, the dust in the air will be evenly distributed on the dust removal mechanism, and will not cause a relatively fast local blockage. The dust in the air can be filtered step by step through the dust removal mechanism, and the filtering effect is good. The dust removal mechanism is very convenient to clean and replace. After that, the air will pass through the nano silver antibacterial gel filter screen to achieve the effect of sterilization and virus killing. After that, the air will pass through the photocatalyst filter screen to eliminate harmful substances such as formaldehyde and benzene. After that, it will pass through the activated carbon filter screen to achieve the effect of deodorization. The purified air returns to the outside world, so that the environment is purified and the health of the human body is guaranteed.

[0018] 2. The present invention sets the first mixing plate to be composed of a first frame and a plurality of longitudinal peak-shaped first mixing blocks, and sets the second mixing plate to be composed of a second frame and a plurality of transverse peak-shaped second mixing blocks, so that the air will be blocked by the first mixing block and the second mixing block in turn and will be diverted to both sides of the first mixing block and the second mixing block in turn, so that the dust that may originally be gathered into a mass will be effectively dispersed, and the air between two adjacent first mixing blocks and the air between two adjacent second mixing blocks will form a cross-mixing, which greatly improves the mixing effect, so that the air entering the air purification device is not only longitudinally mixed but also transversely mixed, so that the mixing is sufficient. In addition, the first mixing plate and the second mixing plate of this form can block relatively large solid impurities in the air, such as hair, etc., and have a good effect of initial screening of the air;

[0019] 3. The present invention configures the dust removal mechanism to consist of a primary dust removal plate, a secondary dust removal plate and a tertiary dust removal plate, wherein the first vertical partition plate on the back of the primary dust removal plate divides the filter holes on the secondary dust removal plate into two even parts, and the mesh plate on the back of the secondary dust removal plate divides the filter holes on the tertiary dust removal plate into four even parts, so that the dust in the air can be filtered step by step, so that the filter holes are not easily blocked, and at the same time, the left and right widths of the dust removal mechanism are greatly stretched, so that the entire dust removal mechanism can accommodate a larger amount of dust, so that the dust removal mechanism is not easily blocked, thereby enhancing the efficiency and effect of purification, and at the same time, there is no need to frequently clean the dust removal mechanism. The dust mechanism is cleaned and replaced, wherein the arrangement of the first vertical partition plate and the mesh plate will form a narrow air duct between the primary dust removal plate and the secondary dust removal plate, and between the secondary dust removal plate and the tertiary dust removal plate, and the air duct can accelerate the speed and strength of air propagation, so as to have a good impact on the filter hole, so that the dust adhering to the edge of the filter hole is blown away in time, further ensuring the smoothness of the filter hole, making it difficult to be blocked, and at the same time greatly improving the purification efficiency. In addition, the arrangement of the first vertical partition plate and the mesh plate can easily clean the secondary dust removal plate and the tertiary dust removal plate, specifically by moving and scraping;

[0020] 4. The present invention arranges U-shaped grooves, connecting rods and brush rollers on the first vertical partition and the second vertical partition, so that the dust accumulated on the secondary dust removal plate and the tertiary dust removal plate can be thoroughly removed, and the cleaning effect is better. Moreover, the brush roller is relatively soft, which plays a good protective role on the secondary dust removal plate and the tertiary dust removal plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the attached embodiment of the present invention Figure 1-12 The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention provides a technical solution: an air purification device, comprising a power assembly 1, a filter assembly 2 is connected to the right side of the power assembly 1, the filter assembly 2 comprises a fixed frame 3 fixed to the right side of the power assembly 1, a first mixing plate 4, a second mixing plate 5, a dust removal mechanism 6, a nano silver antibacterial gel filter 7, a photocatalyst filter 8 and an activated carbon filter 9 are sequentially plugged into the fixed frame 3 from right to left, an air inlet 10 is opened on the right side of the fixed frame 3, and a top cover 11 is detachably connected to the top of the fixed frame 3. The present invention fully mixes the air entering the air purification device through the arrangement of the first mixing plate 4 and the second mixing plate 5, and the air is purified. The air in the air purification device is fully mixed by the first mixing plate 4 and the second mixing plate 5, and then the dust is fully filtered after passing through the dust removal mechanism 6. After the initial mixing, the dust in the air will be evenly distributed on the dust removal mechanism 6, and will not cause a fast local blockage. After that, the air will pass through the nano silver antibacterial gel filter 7, which has the effect of sterilizing and killing viruses. After that, the air will pass through the photocatalyst filter 8, which has the effect of eliminating harmful substances such as formaldehyde and benzene. After that, it passes through the activated carbon filter 9, which has the effect of removing odors. The purified air returns to the outside world, so that the environment is purified and the health of the human body is guaranteed. The air purification device can be made into a small size or a large size. The small size can be used indoors at home or in the office, and the large size can be used in the factory or outdoors where the environmental pollution is serious.

[0036] The first mixing plate 4 includes a first frame 12, and a plurality of first mixing blocks 13 with peak-shaped cross sections are fixed between the upper and lower inner edges of the first frame 12, and a first air duct 14 is left between adjacent first mixing blocks 13. The second mixing plate 5 includes a second frame 15, and a plurality of second mixing blocks 16 with peak-shaped cross sections are fixed between the left and right inner edges of the second frame 15, and a second air duct 17 is left between adjacent second mixing blocks 16. When the outside air is sucked into the air purification device from the air inlet 10, it first contacts the first mixing block 13 on the first mixing plate 4. Since the first mixing block 13 is set to be in the shape of a peak, the air will be blocked and diverted to both sides of the first mixing block 13, so that the dust that may have originally gathered into a mass will be effectively dispersed, and the air between two adjacent first mixing blocks 13 will form a cross-mixing, and the mixing effect is good. The principle of the second mixing plate 5 is the same as that of the first mixing plate 4, except that the second mixing plate 16 is arranged horizontally, so that the air entering the air purification device is mixed not only longitudinally but also horizontally, thereby fully mixing the air. In addition, the first mixing plate 4 and the second mixing plate 5 of this form can block relatively large solid impurities in the air, such as hair, etc., and have a good effect of preliminary screening of the air.

[0037] The dust removal mechanism 6 is sequentially arranged from right to left as a primary dust removal plate 18, a secondary dust removal plate 19 and a tertiary dust removal plate 20. The primary dust removal plate 18, the secondary dust removal plate 19 and the tertiary dust removal plate 20 are provided with filter holes 21 of equal number and same specifications. A plurality of first vertical partitions 22 are arranged on the left end face of the primary dust removal plate 18. The right end face of the first vertical partition 22 is fixed on the interval between two adjacent longitudinal columns of filter holes 21, and its left end face is connected to the right end face of the secondary dust removal plate 19. The filter holes 21 on the secondary dust removal plate 19 are divided into two parts. A mesh plate 23 is provided on the left end surface of the secondary dust removal plate 19. The right end surface of the mesh plate 23 is fixed on the interval between the filter holes 21. The left end surface of the mesh plate 23 contacts the right end surface of the tertiary dust removal plate 20. The filter holes 21 on the tertiary dust removal plate 19 are divided into four parts. The size of the filter holes 21 is set according to needs. The primary dust removal plate 18, the secondary dust removal plate 19 and the tertiary dust removal plate 20 are adjacent to each other in sequence. Figure 5 As shown, Figure 6 yes Figure 5 The disassembly diagram of the , it should be noted here that, for the sake of clarity, Figure 5 and Figure 6 The dust removal mechanism 6 and Figure 2 The left and right ends of the dust removal mechanism 6 are exchanged, and the description of the left and right is based on Figure 1 For reference, Figure 5 , Figure 6The left is described as right, and the right is described as left. The first vertical partition 22 on the back of the first-level dust removal plate 18 divides the filter holes 21 on the second-level dust removal plate 19 into two even parts, and the grid plate 23 on the back of the second-level dust removal plate 19 divides the filter holes on the third-level dust removal plate 20 into four even parts, so that the dust in the air can be filtered step by step. For example, the first-level dust removal plate 18 can filter dust with a diameter greater than d, then the second-level dust removal plate 19 can filter dust with a diameter less than d and more than 1 / 2d, and the third-level dust removal plate 19 can filter dust with a diameter less than 1 / 2d and more than 1 / 4d. In this way, the dust in the air is filtered step by step, so that the filter holes 21 are not easy to be blocked. At the same time, the left and right widths of the dust removal mechanism 6 are greatly stretched, so that the entire dust removal mechanism 6 can accommodate a larger amount of dust, so that the dust removal mechanism 6 is not easy to be blocked, thereby enhancing the efficiency and effect of purification, and there is no need to frequently clean and replace the dust removal mechanism 6. However, because the prior art often only has a relatively thin filter plate, the filter holes thereon are easily blocked and need to be frequently cleaned or replaced, which is very troublesome. The arrangement of the first vertical partition 22 and the mesh plate 23 will form a narrow air duct between the primary dust removal plate 18 and the secondary dust removal plate 19, and between the secondary dust removal plate 19 and the tertiary dust removal plate 20. The air duct can accelerate the speed and strength of air propagation, thereby having a good impact on the filter hole 21, so that the dust adhering to the edge of the filter hole 21 is blown away in time, further ensuring the smoothness of the filter hole 21, making it not easy to be blocked, and also greatly improving the purification efficiency. In addition, the arrangement of the first vertical partition 22 and the mesh plate 23 can easily clean the secondary dust removal plate 19 and the tertiary dust removal plate 20. When the secondary dust removal plate 19 needs to be cleaned, it is only necessary to slowly pull the primary dust removal plate 18 out of the air purifier. In the process of slowly pulling out, the first vertical partition 22 will scrape off the dust accumulated on the surface of the secondary dust removal plate 19, and multiple first vertical partitions 22 can perform multiple scrapings, and the scraping effect is good. When the tertiary dust removal plate 20 needs to be cleaned, it is only necessary to slowly pull the secondary dust removal plate 19 out of the air purifier, and the mesh plate 23 can scrape off the dust on the tertiary dust removal plate 20. In addition, by splicing the primary dust removal plate 18, the secondary dust removal plate 19 and the tertiary dust removal plate, it is convenient to finally clean the dust removal mechanism 6, and there will be no situation where the middle part cannot be cleaned. It should also be noted that the dust removal mechanism 6 is not limited to a three-stage dust removal setting, and the dust removal mechanism 6 can be set to a multi-stage dust removal as needed, and the filter holes 21 can be divided into two, four, eight, sixteen, etc. step by step.

[0038] The shape of the filter hole 21 is a square, wherein the shape of the filter hole 21 is set to be a square, so that it is convenient to divide the filter hole 21 into even equal parts, such as evenly dividing into two equal parts, four equal parts, eight equal parts, etc.

[0039] A U-shaped groove 25 is provided at the left end of the second vertical partition 24 on the first vertical partition 22 and the mesh plate 23, and a connecting rod 26 is connected between the upper and lower ends of the U-shaped groove 25, and a brush roller 27 is rotatably connected between the two connecting rods 26. When the first vertical partition 22 and the mesh plate 23 scrape the secondary dust removal plate 19 and the tertiary dust removal plate 20, the dust accumulated on the secondary dust removal plate 19 and the tertiary dust removal plate 20 can be more effectively removed and removed more thoroughly, and the brush roller 27 is relatively soft, which plays a good protective role on the secondary dust removal plate 19 and the tertiary dust removal plate 20.

[0040] The fixed frame 3 is provided with a first mixing plate plug-in slot 28, a second mixing plate plug-in slot 29, a dust removal mechanism plug-in slot 30, a nano silver antibacterial gel filter plug-in slot 31, a photocatalyst filter plug-in slot 32, and an activated carbon filter plug-in slot 33 from right to left, wherein the dust removal mechanism plug-in slot 30 is sequentially plugged with a primary dust removal plate 18, a secondary dust removal plate 19 and a tertiary dust removal plate 20. This plug-in method facilitates the installation and disassembly of the first mixing plate 4, the second mixing plate 5, the primary dust removal plate 18, the secondary dust removal plate 19 and the tertiary dust removal plate 20, the nano silver antibacterial gel filter 7, the photocatalyst filter 8 and the activated carbon filter 9.

[0041] Handles 34 are fixed on the outer surfaces of the first mixing plate 4, the second mixing plate 5, the first dust removal plate 18, the second dust removal plate 19 and the third dust removal plate 20, the nano silver antibacterial gel filter 7, the photocatalyst filter 8 and the activated carbon filter 9. The handles 34 are arranged to facilitate the first mixing plate 4, the second mixing plate 5, the first dust removal plate 18, the second dust removal plate 19 and the third dust removal plate 20, the nano silver antibacterial gel filter 7, the photocatalyst filter 8 and the activated carbon filter 9 to be pulled out from the fixed frame 3.

[0042] The power assembly 1 includes a vertical box 35, a control panel 36 is provided on the upper part of the vertical box 1, a suction fan 37 is provided on the lower part, and an air outlet is provided on the vertical box 1. When working, air is sucked in through the suction fan 37, and the control panel can adjust the wind speed, temperature, humidity, etc.

[0043] Working principle: When working, the suction fan 37 sucks the outside air into the air purification device, and the air entering the air purification device is fully mixed through the arrangement of the first mixing plate 4 and the second mixing plate 5. The air in the air purification device is fully mixed after passing through the first mixing plate 4 and the second mixing plate 5, and then passes through the dust removal mechanism 6 to fully filter the dust. After the initial mixing, the dust in the air will be evenly distributed on the dust removal mechanism 6, and will not cause a rapid local blockage. The dust in the air can be filtered step by step through the dust removal mechanism 5, and the filtering effect is good. The dust removal mechanism 6 is very convenient to clean and replace. After that, the air will pass through the nano silver antibacterial gel filter 7, which has the effect of sterilization and virus killing. After that, the air will pass through the photocatalyst filter 8, which has the effect of eliminating harmful substances such as formaldehyde and benzene. After that, it passes through the activated carbon filter 9, which has the effect of deodorization. The purified air returns to the outside world, so that the environment is purified and the health of the human body is guaranteed. The air purification device can be made into a small size or a large size. The small size can be used indoors at home or in an office, while the large size can be used in a factory or outdoors where the environment is seriously polluted.
