Description

Technical Field

[0001] This utility model relates to the field of oxygen generation equipment technology, specifically an oxygen generator with an easy-to-replace filter element. Background Technology

[0002] Currently, some oxygen concentrators are inconvenient to replace their filters after prolonged use. The filter is one of the main components of an oxygen concentrator. A search revealed existing technology with announcement number CN214597883U, whose general solution is as follows: The system uses components such as a support block, a locking rod, a sliding rod, a first spring, a second spring, and a filter. The locking rod limits the position of the support block, while the sliding rod and the locking block further limit the support block, facilitating filter installation. The first spring allows the sliding rod to automatically rebound upwards, and the second spring allows the locking block to automatically reset.

[0003] It can be seen that in the existing technology, the filter element must first be replaced by stopping the machine. Secondly, the components such as the support block, clamping rod, sliding rod, first spring, second spring and filter element need to be disassembled, which results in a long filter element replacement time. Utility Model Content

[0004] The purpose of this invention is to provide an oxygen generator with an easy-to-replace filter element, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oxygen concentrator with an easy-to-replace filter element, comprising a housing, an air compressor housed within the housing, and a filter element assembly housed on the side of the housing; the air compressor is connected to the filter element assembly via an air inlet pipe; the filter element assembly includes a housing, which is connected to the air inlet pipe via an air inlet; a support shaft is housed within the housing, and a support plate is rotatably mounted on the support shaft, with a through hole on the support plate; a support cylinder is also provided on the side of the support plate facing the housing; wherein the support cylinder has a mesh structure, and there are multiple support cylinders arranged circumferentially on the support plate; a filter element is housed within the support cylinder, and by rotating the support plate, an air outlet on the bottom surface of the support cylinder is connected to the air inlet.

[0006] As a preferred technical solution of this utility model, it also includes fasteners; by loosening the fasteners, the support plate can be rotated on the support shaft, and by tightening the fasteners, the bottom surface of the support cylinder can be pressed against the housing.

[0007] As a preferred technical solution of this utility model: a sealing gasket is also provided on the bottom surface of the support cylinder, and the sealing gasket is pressed against the outside of the air inlet to complete the sealing between the air inlet and the air outlet.

[0008] As a preferred technical solution of this utility model, it also includes a plug, which is connected to the support plate to fix the filter element inside the support cylinder.

[0009] As a preferred technical solution of this utility model: the housing is further provided with a positioning mark line, and the support plate is further provided with an indicator arrow.

[0010] The beneficial effects of this utility model by adopting the above technical solution are: 1. Since there are multiple support cylinders on the support plate, and the support plate can rotate on the support shaft, the air outlet of the support cylinder can be aligned with the air inlet by rotating the support plate, so that the filter element can be replaced simply and conveniently, thereby shortening the filter element replacement time.

[0011] 2. Since there are multiple support cylinders, when one support cylinder is aligned with the air inlet, the other support cylinder is separated from the air inlet. At this time, the user can take out the filter element in the other support cylinder. Therefore, by using multiple support cylinders to alternately connect with the air inlet, the filter element can be replaced without stopping the machine, and the replaced filter element can be cleaned.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0019] Please see Figure 1-5 This utility model provides an embodiment of an oxygen generator with an easy-to-replace filter element, comprising a housing 1, an air compressor 4 inside the housing 1, and a filter element assembly 3 on the side of the housing 1; the air compressor 4 is connected to the filter element assembly 3 through an air inlet pipe 2; the filter element assembly 3 includes a housing 30, which is connected to the air inlet pipe 2 through an air inlet 32; a support shaft 31 is provided inside the housing 30, and a support plate 36 is rotatably mounted on the support shaft 31, and the support plate 36 is provided with a through hole 310; a support cylinder 35 is provided on the side of the support plate 36 facing the housing 30; wherein, the support cylinder 35 has a mesh structure, and there are multiple support cylinders 35 arranged circumferentially on the support plate 36; a filter element 39 is provided inside the support cylinder 35, and by rotating the support plate 36, the air outlet 312 on the bottom surface of the support cylinder 35 is connected to the air inlet 32.

[0020] In summary, since the support plate 36 has multiple support cylinders 35, and the support plate 36 can rotate on the support shaft 31, the air outlet 312 of the support cylinder 35 can be aligned with the air inlet 32 ​​by rotating the support plate 36, thus making the replacement of the filter element 39 simple and convenient, shortening the replacement time of the filter element 39. At the same time, since there are multiple support cylinders 35, when one support cylinder 35 is aligned with the air inlet 32, the other support cylinder 35 is separated from the air inlet 32. At this time, the user can take out the filter element 39 in the other support cylinder 35; or take it out after the filter element 39 has been used up. Therefore, by using the alternating connection of multiple support cylinders 35 with the air inlet 32, the filter element 39 can be replaced without stopping the machine, and the replaced filter element 39 can be cleaned. The external air source enters the outside of the support cylinder 35 through the through hole 310, and then enters the filter element 39 inside the support cylinder 35 through the mesh support cylinder 35. The air source through the filter element 39 is then transported to the air compressor 4 through the air inlet pipe 2.

[0021] Furthermore, by loosening the fastener 37, the support plate 36 can rotate on the support shaft 31, at which point the old support cylinder 35 is replaced. Then, by tightening the fastener 37 to press the bottom surface of the support cylinder 35 against the housing 30, the new support cylinder 35 can be fixed inside the housing 30. The fastener 37 is preferably a bolt, which is adapted to be connected to the external threaded post at the end of the support shaft 31.

[0022] Furthermore, since a sealing gasket 34 is provided on the bottom surface of the support cylinder 35, and the sealing gasket 34 abuts against the outside of the air inlet 32 ​​to complete the seal between the air inlet 32 ​​and the air outlet 312; therefore, by covering the air inlet 32 ​​and the air outlet 312 radially with the sealing gasket 34, the air source can be prevented from entering the air inlet 32 ​​through the gap between the opposing surfaces of the support cylinder 35 and the housing 30; wherein, one end of the sealing gasket 34 is fitted on the end face of the support cylinder 35, and the other end is in contact with the inner wall surface of the housing 30.

[0023] Based on the above solution, the filter element 39 is fixed inside the support cylinder 35 by connecting the plug 38 to the support cylinder 35. Therefore, the plug 38 can be used to prevent the filter element 39 from falling off, and at the same time, the plug 38 can be used to fix the filter element 39 inside the support cylinder 35.

[0024] Furthermore, since the housing 30 is also provided with a positioning mark line 33 and the support plate 36 is also provided with an indicator arrow 311, when the indicator arrow 311 is aligned with the positioning mark line 33, it can remind the user that the air outlet 312 and the air inlet 32 ​​are aligned. Based on this, it can also avoid the phenomenon that the air inlet 32 ​​and the air outlet 312 cannot be aligned due to excessive rotation by the user.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
