Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a filter and an ozone sterilizer containing the filter. Background Technology

[0002] Ozone sterilizers work by using the strong oxidizing properties of ozone to destroy the structure and function of microorganisms, thus achieving sterilization and disinfection. At the same time, ozone decomposes into oxygen on its own, leaving no residual pollution. Therefore, they are widely used in many fields such as medical and health care, food processing, water treatment, public spaces, and home life.

[0003] For most civilian ozone sterilizers, the ozone used for sterilization is mainly produced from oxygen in the air. Therefore, in order to protect the ozone generator, extend the equipment life, avoid secondary pollution, and improve the safety of sterilization, a filter device is usually installed on the air intake side of the ozone generator to achieve preliminary filtration of the air.

[0004] In existing technologies, the filters installed on the air intake side of civilian ozone sterilizers typically employ a simple two-stage filtration system to meet the requirements of ozone generators. This consists of a primary filter using a non-woven fabric or sponge filter and a secondary filter made of activated carbon. The primary filter intercepts large particulate impurities such as hair, lint, and dust from the air, while the secondary filter uses activated carbon to adsorb fine dust, formaldehyde, and odor molecules (such as sweat and musty smells) from the air. This improves air freshness while preventing these substances from reacting with ozone to generate byproducts.

[0005] However, after a period of use, the activated carbon intermediate filter needs to be replaced. Since the activated carbon intermediate filter is located on the inside, the primary filter must be removed first when replacing it, which makes the replacement and installation of the activated carbon intermediate filter troublesome. In addition, the adsorption capacity of the activated carbon filter is limited, which shortens its replacement cycle. Furthermore, the primary filter is also prone to clogging, which leads to a shortened cleaning and maintenance cycle for the primary filter, requiring users to perform maintenance frequently.

[0006] Therefore, it is necessary to improve the filters and ozone sterilizers containing filters in the existing technology. Utility Model Content

[0007] The purpose of this invention is to overcome the defects in the existing technology and provide a filter that extends the replacement and maintenance cycle and facilitates replacement and maintenance operations, as well as an ozone sterilizer containing the filter.

[0008] To solve the above-mentioned technical problems, this utility model provides a filter, comprising: The mounting plate is vertically positioned and has circular mounting through holes along its own thickness. The filter shell is horizontal in the axial direction, and its outer edge is sealed to the inner wall of the assembly through hole. It rotates on the mounting plate with the axis of the assembly through hole as the center line. Both ends of the filter shell are densely covered with air vents. The inner cavity of the filter shell is used to store granular activated carbon. The inner diameter of the air vents is smaller than the particle size of the activated carbon. The filter shell is fixedly connected to a material pipe. The material pipe is located on the air inlet side of the mounting plate and is detachably connected to a sealing plug. A primary filter layer is detachably attached to the air inlet end of the filter housing; A flow guide is disposed on the air outlet side of the mounting plate and forms a flow guide cavity with the mounting plate and the filter shell. The flow guide is fixedly connected to an air outlet pipe that communicates with the flow guide cavity. The air outlet pipe is used to connect to an ozone generator.

[0009] Preferably, in order to facilitate fixing the position of the feed tube and to facilitate the replenishment of activated carbon particles into the filter shell, a locking component is also included. The locking component is used to lock the feed tube at the feeding station, where the feed tube extends vertically and the top opening is set upward.

[0010] Preferably, in order to achieve position locking of the material tube, the locking assembly includes a locking sleeve, which slides vertically on the air inlet side of the mounting plate. The sliding trajectory of the locking sleeve includes a locking position and a release position located above the locking position. The outer circumferential edge of the material tube under the injection position is sealed and fitted with the inner circumferential wall of the locking sleeve under the locking position. Under the release position, the locking sleeve is located above the material tube and is separated from the material tube.

[0011] Preferably, to facilitate the assembly of the filter housing, the filter housing includes an axially horizontal filter cylinder and mesh plates fixed to both ends of the filter cylinder, with the air vents disposed on the mesh plates.

[0012] Preferably, in order to increase the capacity of the filter shell, the mesh plates at both ends of the filter cylinder have concave surfaces facing each other with the notches facing each other.

[0013] Preferably, in order to reduce dust accumulation in the primary filter layer and extend the cleaning and maintenance cycle, both sides of the mesh plate and both sides of the primary filter layer are spherical surfaces, and the mesh plate located at the air inlet end of the filter cylinder is bonded to the primary filter layer.

[0014] Preferably, for the portable and detachable connection of the primary filter layer, an assembly ring is fixedly connected to the circumferential outer edge of the primary filter layer, and the filter shell is magnetically connected to the assembly ring.

[0015] Preferably, in order to ensure a precise and detachable connection between the primary filter layer and the filter housing, a positioning sleeve and a positioning shaft are provided between the circumferential outer edge of the filter housing and the assembly ring, which are inserted and fitted along the axis parallel to the assembly through hole.

[0016] Preferably, in order to facilitate monitoring of the usage status of the primary filter and the activated carbon inside the filter housing, the exhaust pipe is connected to a VOC sensor and a flow sensor.

[0017] To solve the above-mentioned technical problems, this utility model also discloses an ozone sterilizer, comprising: The outer shell houses an ozone generator and a disinfection chamber. The output of the ozone generator is connected to the disinfection chamber. The outer shell is provided with an installation through hole and a pick-up / placement port. The pick-up / placement port is connected to the disinfection chamber and is detachably covered with a cover plate. As described in any of the above technical solutions, the filter mounting plate is disposed on the mounting through hole, and the air outlet pipe is located inside the housing and connected to the input end of the ozone generator.

[0018] In summary, compared with the prior art, the filter of this utility model and the ozone sterilizer containing the filter can be easily adjusted by rotating the filter shell on the mounting plate. When it is necessary to replace the activated carbon, the filter shell can be discharged downwards to remove the sealing plug, which facilitates the discharge of activated carbon. Then the filter shell can be adjusted upwards to facilitate the replenishment of activated carbon into the filter shell. The activated carbon can be replaced without removing the primary filter layer, making maintenance convenient and quick. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] like Figures 1-4 As shown, a filter according to this utility model includes: Mounting plate 1 is vertically arranged and has circular mounting through holes 11 along its own thickness direction; The filter shell 2 is horizontal in the axial direction. Its outer edge is sealed to the inner wall of the assembly through hole 11 and rotates on the mounting plate 1 with the axis of the assembly through hole 11 as the center line. Both ends of the filter shell 2 are densely covered with air vents 221. The inner cavity of the filter shell 2 is used to store granular activated carbon. The inner diameter of the air vents 221 is smaller than the particle size of the activated carbon. The filter shell 2 is fixedly connected to a material pipe 214. The material pipe 214 is located on the air inlet side of the mounting plate 1 and is detachably connected to a sealing plug 215. Primary filter layer 3 is detachably covered at the air inlet end of filter housing 2; The air guide 4 is set on the air outlet side of the mounting plate 1 and forms an air guide cavity with the mounting plate 1 and the filter shell 2. The air guide 4 is fixedly connected to the air outlet pipe 41, which is connected to the air guide cavity. The air outlet pipe 41 is used to connect to the ozone generator.

[0022] The filter of this utility model is set at the air inlet of the ozone sterilizer. Its mounting plate 1 is used to fix it on the ozone sterilizer. After installation, when the ozone sterilizer is running, the outside air is introduced from the outside and filtered through the filter. The primary filter layer 3 is used to filter large particulate impurities such as hair, cotton wool, and dust in the air. The primary filter layer 3 is preferably a sponge filter layer or a non-woven fabric filter layer.

[0023] After initial filtration through the primary filter layer 3, the outside air then comes into contact with activated carbon particles in the inner cavity of the filter shell 2 through the vent 221 at the air inlet end. The activated carbon particles adsorb fine dust, formaldehyde, and musty and sweat odor molecules in the air, further purifying the air. The purified air is discharged from the vent 221 at the other end and enters the guide hood 4. After being discharged through the air outlet pipe 41 of the guide hood 4, it enters the ozone generator to produce ozone for sterilization and disinfection.

[0024] Unlike existing technologies, the filter shell 2 of this invention can rotate inside the assembly through hole 11 while maintaining a sealed connection between its outer circumferential edge and the inner circumferential wall of the assembly through hole 11. With this structure, the orientation of the feed pipe 214 of the filter shell 2 can be adjusted to meet different usage needs.

[0025] Specifically, when the activated carbon becomes saturated and needs replacement, simply rotate the filter shell 2 so that the end of the feed pipe 214 furthest from the filter shell 2 faces downwards, then unscrew the sealing plug 215 to allow the activated carbon inside the filter shell 2 to drain downwards through the feed pipe 214. After the activated carbon is drained, adjust the orientation of the feed pipe 214 so that the end furthest from the filter shell 2 faces upwards, then replenish activated carbon into the filter shell 2 through the feed pipe 214. After replenishment, replace the sealing plug 215 to block the feed pipe 214. Therefore, the filter of this invention allows for the draining, replenishment, and replacement of activated carbon inside the filter shell 2 without disassembling the primary filter layer 3, making maintenance more convenient.

[0026] When a large amount of particulate impurities accumulate on the surface of the primary filter layer 3, the primary filter layer 3 can be removed from the end of the filter housing 2. The primary filter layer 3 can then be cleaned and maintained to remove the impurities attached to its surface before being installed back onto the filter housing 2.

[0027] A further improvement is that it also includes a locking component 5, which is used to lock the material tube 214 at the injection station, where the material tube 214 extends vertically and the top opening is set upward.

[0028] With the above design, the material tube 214 can be easily locked at the injection station by the locking component 5, so that the material tube 214 is kept in the upward position, which makes it convenient to inject activated carbon particles into the filter shell 2 through the material tube 214 at this station.

[0029] In order to lock the position of the material tube 214, the locking component 5 in this utility model includes a locking sleeve 51. The locking sleeve 51 slides vertically on the air inlet side of the mounting plate 1. The sliding trajectory of the locking sleeve 51 includes a locking position and a release position located above the locking position. The outer circumferential edge of the material tube 214 under the injection position is sealed and fitted with the inner circumferential wall of the locking sleeve 51 under the locking position. Under the release position, the locking sleeve 51 is located above the material tube 214 and is separated from the material tube 214.

[0030] Specifically, the locking assembly 5 also includes a slide rail 52 fixed to the mounting plate 1 and extending vertically above the mounting through hole 11. The slide rail 52 has a T-shaped cross-section and a slider 53 slides on the slide rail 52. The slider 53 is integrally connected to the locking sleeve 51. Limiting protrusions 521 are fixed at both ends of the side of the slide rail 52 facing away from the mounting plate 1 to limit the sliding range of the slider 53 and the locking sleeve 51.

[0031] With the above structure, when the slider 53 contacts the top limiting protrusion 521, the locking sleeve 51 is in the separation position. The filter housing 2 and the feed tube 214 can rotate around the axis of the assembly through hole 11. When the feed tube 214 is rotated to the bottom of the filter housing 2, so that the opening of the feed tube 214 is facing downwards, the sealing plug 215 can be removed to facilitate the discharge of saturated activated carbon particles. When the feed tube 214 is rotated to the top of the filter housing 2, the opening of the feed tube 214 is facing upwards. At this time, the feed tube 214 and the locking sleeve 51 are on the same axis. The locking sleeve 51 is then slid downwards through the sliding block 53 and the slide rail 52, so that the locking sleeve 51 is sealed on the feed tube 214 from the upper right to the lower right. The bottom of the locking sleeve 51 contacts the lower limiting protrusion 521. At this time, the locking sleeve 51 is in the locking position, which can lock the position of the feed tube 214, so that the feed tube 214 is kept upwards, which facilitates the injection of activated carbon particles into the filter housing 2 through the feed tube 214.

[0032] A further improvement is that the filter housing 2 includes an axially horizontal filter cylinder 21 and mesh plates 22 fixed at both ends of the filter cylinder 21, with air vents 221 provided on the mesh plates 22.

[0033] This design facilitates the assembly of the filter housing 2. More specifically, the outer circumferential edge of the filter cylinder 21 has two integrally formed protruding rings 213. The mounting plate 1 is located inside the two protruding rings 213. An annular rubber ring 23 is also fixed between the outer circumferential edge of the filter cylinder 21 and the two protruding rings 213. An annular sealing groove is integrally formed on the rubber ring 23. The side wall of the sealing groove is in close contact with the inner circumferential wall of the assembly through hole 11 and the two sides. In this way, excessive wear is avoided when the rigid filter housing 2 and the rigid mounting plate 1 rotate relative to each other, ensuring the installation seal.

[0034] A further improvement is that the mesh plates 22 at both ends of the filter cylinder 21 have concave surfaces facing each other, and the notches are set directly opposite each other.

[0035] With the above design, the inner cavity of the filter shell 2 is increased by the two mesh plates 22 having opposing recesses integrally formed, thereby increasing the amount of activated carbon particles that can be temporarily stored in the filter shell 2, so as to adsorb more impurity gases and extend the replacement cycle of activated carbon particles.

[0036] A further improvement is that the curved surfaces of both sides of the mesh plate 22 and both sides of the primary filter layer 3 are spherical, and the mesh plate 22 located at the air inlet end of the filter cylinder 21 is attached to the primary filter layer 3.

[0037] The above design results in a hemispherical curved surface for the primary filter layer 3. This reduces dust accumulation and clogging, while also improving filtration efficiency. Specifically, compared to a vertical plane, during filtration, the airflow disperses along the tangent of the curved surface when passing through the primary filter layer 3. This allows dust particles to adhere evenly to the entire outer surface of the primary filter layer 3, preventing excessive local dust accumulation. Furthermore, the curved surface facilitates force dispersion in the primary filter layer 3, resulting in loose dust adhesion and preventing compaction of the gaps. This allows airflow to pass through the surrounding gaps, ensuring even dust accumulation across the entire surface of the primary filter layer 3. The air resistance increases slowly, resulting in a longer clogging cycle compared to a planar structure. In addition, the spherical structure of the primary filter layer 3 makes cleaning and maintenance easier. Only the convex surface needs to be rinsed with water, without repeated rubbing. In contrast, planar sponge or non-woven fabric filter layers require forceful squeezing to remove compacted dust after clogging, which can easily damage the internal structure of the sponge or non-woven fabric.

[0038] A further improvement is that an assembly ring 31 is fixedly connected to the circumferential outer edge of the primary filter layer 3, and the filter housing 2 is magnetically connected to the assembly ring 31. This magnetic connection facilitates quick disassembly and reassembly of the assembly ring 31 and the filter housing 2, thereby facilitating the quick disassembly and reassembly of the primary filter layer 3 and the filter housing 2 for cleaning and maintenance of the primary filter layer 3.

[0039] A further improvement is that a positioning sleeve 211 and a positioning shaft 311 are provided between the circumferential outer edge of the filter shell 2 and the assembly ring 31, which are axially inserted and fitted parallel to the assembly through hole 11.

[0040] Specifically, the filter cartridge 21 has a ring array of positioning sleeves 211 integrally connected to it on its outer circumferential edge. A magnet 212 is fixed on the side of the positioning sleeve 211 facing away from the mounting plate 1. The magnet 212 has a through hole. The through hole is coaxial with the inner circumferential wall of the positioning sleeve 211 and its inner diameter is larger than that of the positioning sleeve 211. The assembly ring 31 has a ring array of protrusions 32 corresponding to the positioning sleeves 211. The protrusions 32 are iron blocks with a rust-proof coating on their surface. A positioning shaft 311 is fixed on the side of the protrusions 32 adjacent to the mounting plate 1. The positioning shaft 311 and the positioning sleeve 211 are inserted and fitted along the axis of the assembly through hole 11.

[0041] After adopting the above results, the magnet 212 can attract the protrusion 32, causing the assembly ring 31 to move towards the filter shell 2. The positioning shaft 311 and the positioning sleeve 211 are interlocked to position the radial position of the primary filter layer 3 relative to the filter shell 2, ensuring that the primary filter layer 3 and the filter shell 2 are coaxial. During disassembly, it is only necessary to control the protrusion 32 to move away from the mounting plate 1 along the axis of the assembly through hole 11, so that the positioning shaft 311 can be disengaged from the positioning sleeve 211 and the magnet 212.

[0042] A further improvement is that the exhaust pipe 41 is connected to a VOC sensor 411 and a flow sensor 412. By setting the flow sensor 412, it is convenient to monitor the air flow rate discharged from the exhaust pipe 41 to preliminarily determine the usage status of the primary filter layer 3, that is, whether the primary filter layer 3 is blocked. The VOC sensor 411 can detect the volatile organic compounds, that is, the VOC content, in the air entering the ozone generator input end, thereby determining the usage status of the activated carbon particles in the filter shell 2, that is, whether adsorption saturation has been reached.

[0043] Based on the above-mentioned filter, this utility model also discloses an ozone sterilizer, comprising: The outer casing 6 has an ozone generator and a disinfection chamber built inside. The output end of the ozone generator is connected to the disinfection chamber. The outer casing 6 is provided with an installation through hole 61 and a pick-up and put-out port. The pick-up and put-out port is connected to the disinfection chamber. The pick-up and put-out port is detachably covered with a cover plate 62. The filter described above has a mounting plate 1 disposed on a mounting through hole 61, and an outlet pipe 41 located inside the housing 6 and connected to the input end of the ozone generator.

[0044] More specifically, the top of the outer casing 6 is equipped with a touch screen 63 for convenient control of the device operation and display of monitoring data from the VOC sensor 411 and flow sensor 412, thereby determining and displaying the clogging status of the primary filter layer 3 and the adsorption status of activated carbon particles in the filter housing 2. The bottom of the outer casing 6 is equipped with casters 64 for easy movement of the device. A heat dissipation vent 67 is also provided at the bottom of the outer casing 6. The ozone generator is fixedly mounted directly above the heat dissipation vent 67 to facilitate heat dissipation during ozone generator operation and prevent it from operating in a closed, high-temperature environment. The mounting through-hole 61 and cover plate 62 are both located on the back of the outer casing 6, with the outer circumferential edge of the mounting plate 1 fixedly connected to the inner circumferential wall of the mounting through-hole 61. The outer casing 6 is connected to a power plug 66 via a power cord 65 for convenient power supply to the device.

[0045] In this ozone sterilizer, the filter housing 2 can be rotated to adjust the position of the feed pipe 214, making it convenient to discharge and replenish the activated carbon inside the filter housing 2 without removing the primary filter layer 3, thus facilitating maintenance. Furthermore, the mesh plates 22 at both ends of the filter housing 2 are concave, increasing the capacity of the filter housing 2 and extending the replacement cycle of the activated carbon. In addition, the primary filter layer 3 adopts a convex curved structure, increasing the filtration area, enhancing the filtration effect, and preventing dust accumulation and clogging, further extending the cleaning and maintenance cycle of the primary filter layer 3 and reducing the maintenance burden on users.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
