Description

Technical Field

[0001] The utility model relates to the technical field of foaming filters, in particular to an adjustable quick-release oxygen foaming filter. Background Art

[0002] An oxygen foaming filter is a filter used for filtering and purifying oxygen, and is mainly applied to various water-containing electrical appliances such as water dispensers. It is usually made of materials such as alumina powder, glass fiber, linear low-density polyethylene, urethane vinyl ether, methyltriethoxysilane, AC foaming agent and auxiliary agents.

[0003] In the prior art, although the filter plays a role in filtering the air flow, it also delays the air flow to a certain extent. Limited by the number of holes and the contact area inside the filter, the filter also limits the maximum air flow rate. When a user uses a partially barreled water under-mounted water dispenser, the water dispenser is limited by the power of the devices inside the water dispenser, and the provided air flow rate is relatively fixed, and the air flow rate cannot be adjusted by changing the filter. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the utility model to solve its technical problems is: an adjustable quick-release oxygen foaming filter, comprising: a through-hole filter; a cylindrical filter, which is used for filtering, and the outer wall of the cylindrical filter is slidably connected to the inner wall of the through-hole filter; a wrapping ring, which is used for accommodating the through-hole filter, and the inner wall of the wrapping ring is slidably connected to the outer wall of the through-hole filter; a combining device, which is used to prevent the through-hole filter and the cylindrical filter from falling off, and the outer wall of the combining device is slidably connected to the outer wall of the wrapping ring; the cylindrical filter includes a filter element column, a blind hole is opened at the bottom of the filter element column, a chamfer groove is opened at the edge of the blind hole, a limiting groove is opened on the outer wall of the filter element column, and the outer wall of the filter element column is slidably connected to the inner wall of the through-hole filter. This filter itself has the ability to change the flow rate of the flowing gas following the change of the air flow size, so that when the air flow rate is faster, the air flow passing through the filter can also become larger.

[0005] Preferably, the combining device includes a fixing ring, a positioning push plate is fixedly connected to the outer wall of the fixing ring, a sliding plate is fixedly connected to the bottom of the fixing ring, a rotating cylinder is rotatably connected to the bottom of the sliding plate, a clamping ring is slidably connected to the inner wall of the fixing ring, the outer walls of the clamping ring and the fixing ring are both slidably connected to the outer wall of the through-hole filter, the top of the through-hole filter is in contact with the bottom of the positioning push plate, and the outer wall of the positioning push plate is slidably connected to the outer wall of the cylindrical filter through the limiting groove. The combining device and the wrapping ring stably wrap the through-hole filter and the cylindrical filter, making it difficult for the through-hole filter and the cylindrical filter to fall off.

[0006] Preferably, the wrapping ring includes a protective cylinder. A sliding groove is formed in the wall of the protective cylinder. An elastic ring is fixedly connected to the bottom of the protective cylinder. A connecting ring is fixedly connected to the bottom of the elastic ring. A limiting ring is fixedly connected to the outer wall of the connecting ring. The outer wall of the protective cylinder is slidably connected to the outer wall of a sliding plate through the sliding groove. The inner wall of the protective cylinder is slidably connected to the inner wall of a through-hole filter element. The bottom of the through-hole filter element contacts the bottom of the limiting ring. Since the disassembly and assembly steps between the wrapping ring and the merging device are simple, the purpose of convenient loading and unloading of the filter element is achieved.

[0007] The beneficial effects of the present utility model are as follows:

[0008] 1. By providing a foaming filter element composed of a through-hole filter element, a cylindrical filter element, a merging device, and a wrapping ring, the present utility model enables the filter element itself to have the ability to change the flow rate of the flowing gas according to the change in the size of the air flow. When the air flow rate is faster, the flow rate of the air flow through the filter element can also increase.

[0009] 2. By providing a merging device and a wrapping ring, the through-hole filter element and the cylindrical filter element are stably wrapped, making it difficult for the through-hole filter element and the cylindrical filter element to fall off, and the disassembly and assembly steps are simple, thus achieving the purpose of convenient loading and unloading.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and design various embodiments with various modifications suitable for specific purposes.

[0016] Embodiment: Please refer to Figure 1 - Figure 4 , the present utility model provides a technical solution: an adjustable quick-release oxygen foaming filter element, comprising: a through-hole filter element 1; a cylindrical filter element 2 for filtering, the outer wall of the cylindrical filter element 2 is slidably connected to the inner wall of the through-hole filter element 1; a wrapping ring 4 for receiving the through-hole filter element 1, the inner wall of the wrapping ring 4 is slidably connected to the outer wall of the through-hole filter element 1; a combining device 3 for preventing the through-hole filter element 1 and the cylindrical filter element 2 from falling off, the outer wall of the combining device 3 is slidably connected to the outer wall of the wrapping ring 4; the cylindrical filter element 2 includes a filter element column 21, a blind hole 22 is opened at the bottom of the filter element column 21, a chamfer groove 23 is opened at the edge of the blind hole 22, a limiting groove 24 is opened on the outer wall of the filter element column 21, the outer wall of the filter element column 21 is slidably connected to the inner wall of the through-hole filter element 1, the position of the filter element is fixed during use, and the filter element is connected to the fixing mechanism in the pipeline through the combining device 3, the wrapping ring 4 and the like, so at this time the positions of the combining device 3 and the wrapping ring 4 are fixed. Since the combining device 3 and the wrapping ring 4 fix the position of the through-hole filter element 1, the position of the through-hole filter element 1 subjected to an upward impact remains unchanged at this time. Due to the setting of the blind hole 22 and the chamfer groove 23 at the bottom of the cylindrical filter element 2, the air flow preferentially enters the blind hole 22 along the chamfer of the chamfer groove 23, and then enters the filter element column 21 through the blind hole 22, and finally flows out from the filter element column 21 to complete the filtration. During this process, due to the impact of the air flow inhaled from the outside and the air flow in the pipeline, the whole cylindrical filter element 2 moves upward along the through hole in the through-hole filter element 1. When the cylindrical filter element 2 extends out of the through-hole filter element 1, the area of the air flow contacting the foaming filter element becomes larger, and at the same time, more holes through which the air flow can overflow from the upper end of the filter element become more. When the air flow decreases, due to the action of gravity, the cylindrical filter element 2 slowly falls back into the through-hole filter element 1, so that the larger the air flow, the more the air flow that the filter element can pass through.

[0017] The merging device 3 includes a fixing ring 31. The outer wall of the fixing ring 31 is fixedly connected with a positioning push plate 32. The bottom of the fixing ring 31 is fixedly connected with a sliding plate 33. The bottom of the sliding plate 33 is rotatably connected with a rotating cylinder 34. The inner wall of the fixing ring 31 is slidably connected with a clamping ring 35. The outer walls of the clamping ring 35 and the fixing ring 31 are both slidably connected with the outer wall of the through-hole filter element 1. The top of the through-hole filter element 1 is in contact with the bottom of the positioning push plate 32. The outer wall of the positioning push plate 32 is slidably connected with the outer wall of the cylindrical filter element 2 through a limiting groove 24. After the cylindrical filter element 2 is placed into the through-hole filter element 1, the merging device 3 is pushed into the wrapping ring 4. At this time, the sliding plate 33 drives the rotating cylinder 34 to slide on the sliding groove 42 until the rotating cylinder 34 contacts the bottom of the sliding groove 42. Since the rotating cylinder 34 moves along the shape of the sliding groove 42 when sliding downward, the bottom edge of the rotating cylinder 34 first contacts the elastic ring 43. Under the reaction force of the elastic ring 43, the rotating cylinder 34 returns to the vertical state and is buckled at a pre-set position at the bottom of the sliding groove 42. At this time, when the fixing ring 31 is lifted upward, due to the limitation caused by the opening at the top of the rotating cylinder 34 and the bottom of the sliding groove 42, the merging device 3 is fixed on the wrapping ring 4.

[0018] The wrapping ring 4 includes a protection cylinder 41. A sliding groove 42 is formed in the wall of the protection cylinder 41. The bottom of the protection cylinder 41 is fixedly connected with an elastic ring 43. The bottom of the elastic ring 43 is fixedly connected with a connecting ring 44. The outer wall of the connecting ring 44 is fixedly connected with a limiting ring 45. The outer wall of the protection cylinder 41 is slidably connected with the outer wall of the sliding plate 33 through the sliding groove 42. The inner wall of the protection cylinder 41 is slidably connected with the inner wall of the through-hole filter element 1. The bottom of the through-hole filter element 1 is in contact with the bottom of the limiting ring 45. The through-hole filter element 1 is placed into the interior of the wrapping ring 4 from top to bottom, so that the bottom of the through-hole filter element 1 contacts the limiting ring 45 on the connecting ring 44. After the cylindrical filter element 2 is placed into the through-hole filter element 1, the merging device 3 is pushed into the wrapping ring 4. At this time, the sliding plate 33 drives the rotating cylinder 34 to slide on the sliding groove 42 until the rotating cylinder 34 contacts the bottom of the sliding groove 42. The wrapping ring 4 cooperates with the merging device 3 to stably fix the through-hole filter element 1 in the wrapping ring 4.

[0019] Working principle:

[0020] During use, when the foaming filter element is placed in the pipeline passage of an under-counter water dispenser for barreled water, the air flow moves upward from bottom to top. When passing through the foaming filter element, it will first impact the bottoms of the through-hole filter element 1 and the cylindrical filter element 2. Since the filter elements are fixed in position during use, and the filter elements are connected to the fixing mechanism in the pipeline through the merging device 3, the wrapping ring 4, the merging device 3 and the wrapping ring 4 are fixed in position at this time. Since the merging device 3 and the wrapping ring 4 fix the position of the through-hole filter element 1, the position of the through-hole filter element 1 subjected to the upward impact remains unchanged at this time. Due to the arrangement of the blind hole 22 and the chamfer groove 23 at the bottom of the cylindrical filter element 2, the air flow preferentially enters the blind hole 22 along the chamfer of the chamfer groove 23, then enters the filter element column 21 through the blind hole 22, and finally flows out from the filter element column 21 to complete the filtration. During this process, due to the impact of the air flow inhaled from the outside and the air flow in the pipeline, the entire cylindrical filter element 2 moves upward along the through-hole in the through-hole filter element 1, and under the restriction of the positioning push plate 32 on the limiting groove 24, the cylindrical filter element 2 extends out of the through-hole filter element 1 and does not detach from the through-hole filter element 1. When the cylindrical filter element 2 extends out of the through-hole filter element 1, the area of the air flow contacting the foaming filter element becomes larger, and at the same time, there are more holes through which the air can overflow from the upper end of the filter element. When the air flow decreases, due to the action of gravity, the cylindrical filter element 2 slowly falls back into the through-hole filter element 1, so that the larger the air flow, the more air flow the filter element can pass through, thus achieving the purpose of adjusting the air flow through amount.

[0021] The merging device 3 and the wrapping ring 4 are provided to position the through-hole filter element 1. The through-hole filter element 1 is placed into the interior of the wrapping ring 4 from top to bottom, such that the bottom of the through-hole filter element 1 contacts the limiting ring 45 on the connecting ring 44. After the cylindrical filter element 2 is placed into the through-hole filter element 1, the merging device 3 is pushed into the wrapping ring 4. At this time, the sliding plate 33 drives the rotating cylinder 34 to slide on the sliding groove 42 until the rotating cylinder 34 contacts the bottom of the sliding groove 42. Since the rotating cylinder 34 moves along the shape of the sliding groove 42 when sliding downward, the bottom edge of the rotating cylinder 34 preferentially contacts the elastic ring 43. Under the reaction force of the elastic ring 43, the rotating cylinder 34 is restored to the vertical state and is buckled at a preset position at the bottom of the sliding groove 42. At this time, when the fixing ring 31 is lifted, since the top of the rotating cylinder 34 and the bottom of the sliding groove 42 are grooved to generate a limit, the merging device 3 is fixed on the wrapping ring 4. To remove the merging device 3, just rotate the fixing ring 31 along the rotation direction of the sliding plate 33, such that the sliding plate 33 is slightly deformed and jumps out of the sliding groove 42, then the removal can be completed. The snap ring 35 in the fixing ring 31 and the outer wall of the through-hole filter element 1 have an interference fit, such that the fixing ring 31 limits the top of the through-hole filter element 1 to prevent the through-hole filter element 1 from detaching from the protection cylinder 41 under the impact of air flow. The positioning push plate 32 on the fixing ring 31, while the fixing ring 31 is fixed, embeds the bottom protruding part into the gap formed by the limiting groove 24, thereby completing the limitation of the cylindrical filter element 2 and preventing the cylindrical filter element 2 that moves upward under the impact of air flow from detaching from the through-hole filter element 1.
