Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically a novel indoor air purification device. Background Technology

[0002] Air purifiers are a type of high-tech electrical appliance that is currently popular in the era of green environmental protection and health. Their main function is to comprehensively purify the air in relatively enclosed environments such as offices, public spaces, homes, and vehicles, addressing various physical, chemical, and microbial air pollutants.

[0003] During the use of air purifiers, if the working time is long, some dust and other impurities will often be absorbed on the surface of the internal cavity and the external air inlet. If they are not cleaned in time, they may affect the performance of the air purifier. However, existing air purifiers are generally cleaned by disassembly and cleaning, but this method is not only time-consuming, but may also cause damage to the internal connecting parts during disassembly.

[0004] Therefore, since it does not meet the existing needs, we propose a new type of indoor air purification device. Utility Model Content

[0005] This utility model provides a novel indoor air purification device, which has beneficial effects and solves the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a novel indoor air purification device, comprising a cylinder with a mounting base, the cylinder being divided into a first connecting cylinder, a protective cylinder and a second connecting cylinder, a groove being provided on the top surface of the mounting base, a gear disk being provided inside the groove, and the gear disk being provided with a driving gear and several driven gears, and the top of the driving gear being fixedly connected to the bottom surface of the transmission rod.

[0007] The second connecting cylinder is equipped with a cleaning assembly, which consists of a transmission rod, a scraper, and a brush plate. The upper surface of the transmission rod is symmetrically provided with scrapers, and each scraper is provided with a brush plate on the surface away from the transmission rod.

[0008] As an optional solution of the novel indoor air purification device described in this utility model, the bottom of the first connecting cylinder is connected to several driven gears inside the mounting base via a connecting rod. The driven gears 113 can rotate around the connecting rod 123. At the same time, a cleaning brush strip is fixedly installed on the mounting base of the first connecting cylinder for cleaning the outer surface of the first connecting cylinder. In addition, two cleaning brush strips are provided on the outer side of the first connecting cylinder, and the two cleaning brush strips are respectively fixedly installed on the surface of the mounting base.

[0009] As an optional solution of the novel indoor air purification device described in this utility model, the diameter of the protective cylinder is larger than the diameter of the second connecting cylinder, and multiple connecting blocks are provided between the protective cylinder and the second connecting cylinder. In addition, a first sound insulation plate is provided on the inner wall of the protective cylinder, and the first sound insulation plate is attached to the inner wall of the protective cylinder.

[0010] As an optional solution of the novel indoor air purification device described in this utility model, the second connecting cylinder is provided with a first exhaust fan, a composite filter component and a second exhaust fan, the top of the second connecting cylinder is provided with a detachable cover plate, and the surface of the cover plate is also provided with multiple air holes, and a second sound insulation plate is provided on the inner wall of the second connecting cylinder.

[0011] As an optional solution of the novel indoor air purification device described in this utility model, the first exhaust fan is disposed below the cover plate, and a composite filter component is disposed below the first exhaust fan. In addition, multiple second exhaust fans are disposed, and are respectively disposed at the bottom of the second connecting cylinder.

[0012] As an optional solution for a novel indoor air purification device according to this utility model, the composite filter component is composed of a pre-filter, a HEPA filter, and an activated carbon filter, wherein the pre-filter, HEPA filter, and activated carbon filter are arranged longitudinally at equal intervals.

[0013] As an optional solution for a novel indoor air purification device according to this utility model, a plurality of damping buffers are installed between the first connecting cylinder and the second connecting cylinder.

[0014] As an optional embodiment of the novel indoor air purification device described in this utility model, the lower end of the drive gear is fixedly connected to the output end of the drive motor, and the drive motor is disposed on the bottom surface of the mounting base.

[0015] This utility model has the following beneficial effects:

[0016] 1. This novel indoor air purification device uses a drive motor to rotate, causing the active and driven gears to rotate together. The first connecting cylinder and transmission rod also rotate together. Because the active and driven gears rotate at different speeds, the difference in their rotation speeds allows for self-cleaning of the inner wall of the second connecting cylinder. The cleaned dust and other impurities are then adsorbed and filtered by the composite filter assembly due to the action of the first exhaust fan. Furthermore, the rotation of the first connecting cylinder allows the pores on its surface to be cleaned by the brush plate. This method effectively removes dust and other impurities adhering to the inside of the second connecting cylinder and the surface of the pores in the first connecting cylinder. Moreover, it exhibits lower rotational resistance and a more stable overall structure compared to conventional rotating components.

[0017] 2. This novel indoor air purification device, on the one hand, reduces the noise generated by the internal parts of the second connecting cylinder due to operation by setting a first sound insulation plate and a second sound insulation plate inside the protective cylinder and the second connecting cylinder respectively. On the other hand, by setting several damping buffers between the first and second connecting cylinders, the vibrations generated inside the second connecting cylinder by the second exhaust fan or the cleaning components during cleaning can be absorbed to varying degrees by the damping buffers. In this way, not only is the stability of the second connecting cylinder guaranteed, but the noise generated by vibration is also reduced to a certain extent. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-3 A novel indoor air purification device includes a cylindrical body 1 with a mounting base 101. The cylindrical body 1 is divided into a first connecting cylinder 102, a protective cylinder 103, and a second connecting cylinder 104. A groove 111 is formed on the top surface of the mounting base 101. A gear disk 112 is arranged inside the groove 111. The gear disk 112 is provided with a driving gear 114 and several driven gears 113. The top of the driving gear 114 is fixedly connected to the bottom surface of the transmission rod 116.

[0027] The second connecting cylinder 104 is equipped with a cleaning component 125, which consists of a transmission rod 116, a scraper 117 and a brush plate 119. The upper surface of the transmission rod 116 is symmetrically provided with scrapers 117, and each scraper 117 is provided with a brush plate 119 on the surface away from the transmission rod 116.

[0028] The bottom of the first connecting cylinder 102 is connected to several driven gears 113 inside the mounting base 101 via a connecting rod 124. The bottom of the protective cylinder 103 is fixedly connected to the top of the first connecting cylinder 102. Meanwhile, the bottom of the second connecting cylinder 104 passes through the protective cylinder 103 and is fixedly installed inside the first connecting cylinder 102. In addition, a cleaning brush is fixedly installed on the mounting base of the first connecting cylinder 102 for cleaning the outer surface of the first connecting cylinder. Furthermore, two cleaning brushes 126 are provided on the outside of the first connecting cylinder 102 and are fixedly installed on the surface of the mounting base 101, thereby effectively ensuring that outside air can enter the interior of the first connecting cylinder 102 through multiple air holes.

[0029] The first exhaust fan 110 is located below the cover plate 123. A composite filter assembly 108 is located below the first exhaust fan 110. In addition, multiple second exhaust fans 109 are provided and are respectively located at the bottom of the second connecting cylinder 104.

[0030] The lower end of the drive gear 114 is fixedly connected to the output end of the drive motor 115, while the drive motor 115 is mounted on the bottom surface of the mounting base 101.

[0031] In this embodiment: when the drive motor 115 mounted on the mounting base 101 is started, since the output end of the drive motor 115 is connected to the drive gear 114, the drive gear 114 and several driven gears 113 meshing with it will rotate. On the one hand, the several driven gears 113 are connected to the first connecting cylinder 102 through the connecting rod 124, so the first connecting cylinder 102 will also rotate with the rotation of the driven gears 113. Since two cleaning brush strips 126 are provided on the surface of the mounting base 101, the two cleaning brush strips 126 will clean the air holes on the surface of the first connecting cylinder 102 to a certain extent as the first connecting cylinder 102 rotates. On the other hand, the drive gear... 114 is connected to the transmission rod 116, which causes the scraper 117 mounted on the surface of the transmission rod 116 and the brush plate 119 set on the surface of the scraper 117 to rotate with the rotation of the transmission rod 116. Since the driving gear 114 and the driven gear 113 rotate at different speeds, the self-cleaning work of the inner wall of the second connecting cylinder 104 can be completed by using the gear rotation difference between the two. The cleaned floating dust and other impurities are adsorbed and filtered by the composite filter assembly 108 due to the action of the first exhaust fan 110. In this way, not only are floating dust and other impurities attached to the inside of the second connecting cylinder 104 and the air holes on the surface of the first connecting cylinder 102 effectively cleaned, but the rotational resistance is also smaller than that of ordinary rotating components, and the overall structure is more stable.

[0032] When air purifiers are used indoors, sufficient noise reduction is also necessary. This application incorporates a multi-layered sound-absorbing structure to isolate the noise generated during operation of the air purifier.

[0033] Example 2

[0034] This embodiment is an improvement based on Embodiment 1, according to... Figure 2 As shown, a plurality of damping buffers 107 are installed between the first connecting cylinder 102 and the second connecting cylinder 104. One end of each damping buffer 107 is fixedly connected to the surface of the first connecting cylinder 102, and the other end of each damping buffer 107 is fixedly connected to the surface of the second connecting cylinder 104.

[0035] The diameter of the protective cylinder 103 is larger than the diameter of the second connecting cylinder 104. At the same time, multiple connecting blocks 106 are provided between the protective cylinder 103 and the second connecting cylinder 104. In addition, a first sound insulation plate 105 is provided on the inner wall of the protective cylinder 103. The first sound insulation plate 105 is attached to the inner wall of the protective cylinder 103. The sound insulation material used for the first sound insulation plate 105 is polyurea aerogel.

[0036] The second connecting cylinder 104 is equipped with a first exhaust fan 110, a composite filter assembly 108, and a second exhaust fan 109. A detachable cover plate 123 is provided at the top of the second connecting cylinder 104, and the surface of the cover plate 123 is also provided with multiple air holes. In addition, a second sound insulation plate 118 is provided on the inner wall of the second connecting cylinder 104, and the sound insulation material used for the second sound insulation plate 118 is also polyurea aerogel.

[0037] In this embodiment: on the one hand, by providing a first sound insulation plate 105 and a second sound insulation plate 118 inside the protective cylinder 103 and the second connecting cylinder 104 respectively, the noise generated by the internal parts of the second connecting cylinder 104 due to operation is reduced to a certain extent. On the other hand, by providing a number of damping buffers 107 between the first connecting cylinder 102 and the second connecting cylinder 104, the damping buffers 107 are of the KHS170-150 type. This allows the vibration generated inside the second connecting cylinder 104 by the second exhaust fan 109 or the vibration generated by the cleaning component 125 during cleaning to be absorbed to different degrees by the damping buffers 107. In this way, not only is the stability of the second connecting cylinder 104 guaranteed, but the noise generated by vibration is also reduced to a certain extent.

[0038] Example 3

[0039] This embodiment is an improvement based on Embodiment 1, according to... Figure 4As shown, the composite filter assembly 108 consists of a primary filter 122, a HEPA filter 121, and an activated carbon filter 120, which are arranged longitudinally at equal intervals.

[0040] In this embodiment: the primary filter 122 is mainly used to filter dust particles larger than five micrometers and is made of polyester fiber; the HEPA filter 121 is mainly used to filter impurities from 0.1 micrometer to 0.3 micrometers; and the activated carbon filter 120 is mainly used to adsorb foreign matter. Therefore, the multi-layer filtration effect of the primary filter 122, HEPA filter 121 and activated carbon filter 120 ensures a better filtration effect.
