Description

Technical Field

[0001] This application relates to the field of oxygen generator technology, and in particular to a self-cleaning air intake grille structure for a diffusion oxygen generator. Background Technology

[0002] Oxygen concentrators produce oxygen using various principles, such as air separation technology and molecular sieve physical adsorption and desorption technology, to meet the oxygen needs of people requiring oxygen therapy. A common type of conventional diffusion-type oxygen concentrator requires an air intake filter to filter the incoming air.

[0003] The existing Chinese patent (authorization announcement number: CN216204150U) mentions a high-altitude diffusion oxygen generator that can filter the airflow by setting a deodorizing frame at the air inlet, and then adsorb odors in the airflow by an activated carbon adsorption mesh plate, thereby reducing the probability of polluted airflow entering the room. It can also buffer the compressed airflow to reduce the impact on the oxygen generator, and at the same time detect the gas quality, so that users can monitor the air quality in real time. It is simple and convenient to operate, and stable and reliable in operation.

[0004] Most existing oxygen concentrators have a filter screen installed inside to filter dust and impurities from the air entering the machine. Although this is simple and easy, dust, hair, and other impurities will accumulate on the filter screen if it is not cleaned for a long time. When the filter screen needs to be maintained, it usually requires disassembling the housing, which is inconvenient. Utility Model Content

[0005] The purpose of this application is to provide a self-cleaning air intake grille structure for a diffusion oxygen generator, in order to solve the problem that the housing or filter screen door often needs to be disassembled when the filter screen needs to be maintained.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A self-cleaning air intake grille structure for a diffusion oxygen concentrator includes a base plate, a housing fixedly connected to the top of the base plate, a door hinged to the outer side of the housing, an oxygen concentrator installed inside the housing, an air intake grille body installed outside the housing, an oxygen outlet pipe installed at the top of the housing and connected to the oxygen concentrator, a control panel installed on the outer side of the housing and electrically connected to the oxygen concentrator, a cleaning mechanism provided on the outer side of the housing, and a protective mechanism provided at the top of the housing.

[0007] By adopting the above technical solution, the oxygen generator is powered on, and then the parameters are preset through the control panel. The oxygen generator is then started, and its internal fan starts working, generating negative pressure suction to draw outside air into the oxygen generator through the air intake grille on the outside of the casing. The oxygen generator then performs gas separation, and the prepared high-purity oxygen is delivered to the oxygen outlet pipe through the oxygen generator's outlet. The cleaning mechanism facilitates the cleaning of the filter plate by the staff, and the protective mechanism reduces the amount of dust entering the oxygen outlet pipe.

[0008] Furthermore, the cleaning mechanism includes a filter frame fixedly connected to the outside of the housing. An air inlet is provided on the outside of the filter frame, and a filter plate is installed on the inside of the air inlet. A movable seat is slidably connected to the inside of the filter frame, and a brush is slidably connected to the outside of the movable seat. The brush abuts against the filter plate when it moves. A drive rod is fixedly connected to the top of the movable seat. The top of the drive rod passes through the filter frame and is fixedly connected to a drive head. The drive rod is slidably connected to the filter frame.

[0009] By adopting the above technical solution, the cleaning can be completed simply by pulling the drive head to move the drive rod, which in turn moves the moving seat. The moving seat then moves the brush to wipe the filter plate. The cleaning can be completed simply by pulling the drive head, thus reducing the workload.

[0010] Furthermore, guide rods are symmetrically fixedly connected to the inner side of the filter frame, one end of the guide rod passes through the movable seat, and the guide rod is slidably connected to the movable seat.

[0011] By adopting the above technical solution, the guide rod provides an additional support point for the moving seat, so that the moving seat can remain stable when moving.

[0012] Furthermore, a slot is provided on the inner side of the movable seat, a movable plate is slidably connected to the inner side of the slot, the outer side of the movable plate is fixedly connected to the brush, a spring is fixedly connected to the outer side of the movable plate, and one end of the spring is fixedly connected to the inner side of the slot.

[0013] By adopting the above technical solution, the elastic potential energy of the spring maintains a certain pressure between the brush and the filter plate, thereby improving the cleaning effect of the brush.

[0014] Furthermore, the inner side of the empty slot is symmetrically provided with sliding grooves, and the outer side of the movable plate is symmetrically fixedly connected with sliders, which are slidably connected to the sliding grooves.

[0015] By adopting the above technical solution, the slider and the groove provide guidance for the moving plate, so that the moving plate maintains the correct motion trajectory when moving.

[0016] Furthermore, the protective mechanism includes a protective seat disposed on the top of the outer shell of the oxygen outlet pipe, connecting plates are symmetrically fixedly connected to the outer side of the protective seat, a rotating shaft is fixedly connected between the two connecting plates, a protective plate is rotatably connected to the outer side of the rotating shaft, the protective plate overlaps with the protective seat, and a buffer pad is fixedly connected to the bottom of the protective plate.

[0017] By adopting the above technical solution, the protective plate is rotated on the shaft by the staff, so that the protective plate is rotated above the protective seat, thereby protecting the oxygen outlet pipe.

[0018] In summary, this application includes at least one of the following beneficial effects; 1. In this application, when cleaning the filter plate, the operator first pulls the drive head to move the drive rod, which in turn moves the moving seat. The moving seat then moves the brush to wipe the filter plate. The cleaning can be completed simply by pulling the drive head, without disassembling the housing, which reduces the workload and improves work efficiency.

[0019] 2. In this application, after the oxygen concentrator is used, the operator can rotate the protective plate on the rotating shaft so that the protective plate is rotated above the protective seat, thereby protecting the oxygen outlet pipe and reducing the risk of dust and insects entering the oxygen concentrator through the oxygen outlet pipe.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a self-cleaning air intake grille structure for a diffusion oxygen generator.

[0024] Reference Figure 1 and Figure 2 A self-cleaning air intake grille structure for a diffusion oxygen generator includes a base plate 1, a housing 2 fixedly connected to the top of the base plate 1, a door 3 hinged to the outside of the housing 2, an oxygen generator 4 installed inside the housing 2, an air intake grille body 5 installed outside the housing 2, an oxygen outlet pipe 6 installed at the top of the housing 2 and connected to the oxygen generator 4, a control panel installed on the outside of the housing 2 and electrically connected to the oxygen generator 4, a cleaning mechanism provided on the outside of the housing 2, and a protective mechanism provided at the top of the housing 2.

[0025] When using oxygen concentrator 4, connect the power supply to oxygen concentrator 4, then complete the parameter preset through the control panel, start oxygen concentrator 4, its internal fan starts to work, generating negative pressure suction, and introduces outside air into oxygen concentrator 4 through the air intake grille body 5 on the outside of the housing 2. Then oxygen concentrator 4 performs gas separation, and the prepared high-purity oxygen is delivered to oxygen outlet pipe 6 through the air outlet of oxygen concentrator 4. The cleaning mechanism makes it easy for staff to clean the filter plate, and the protective mechanism reduces dust from entering oxygen outlet pipe 6.

[0026] Reference Figures 2 to 4 The cleaning mechanism includes a filter frame 7 fixedly connected to the outside of the housing 2. An air inlet 8 is provided on the outside of the filter frame 7. A filter plate is installed on the inside of the air inlet 8. A movable seat 9 is slidably connected to the inside of the filter frame 7. A brush 10 is slidably connected to the outside of the movable seat 9. When the brush 10 moves, it abuts against the filter plate. A drive rod 11 is fixedly connected to the top of the movable seat 9. The top of the drive rod 11 passes through the filter frame 7 and is fixedly connected to a drive head 12. The drive rod 11 is slidably connected to the filter frame 7.

[0027] Among them, the inner side of the filter frame 7 is symmetrically fixedly connected with guide rods 13, one end of the guide rod 13 passes through the movable seat 9, and the guide rod 13 is slidably connected to the movable seat 9.

[0028] In addition, a slot 14 is provided on the inner side of the movable seat 9, and a movable plate 15 is slidably connected to the inner side of the slot 14. The outer side of the movable plate 15 is fixedly connected to the brush 10, and a spring 16 is fixedly connected to the outer side of the movable plate 15. One end of the spring 16 is fixedly connected to the inner side of the slot 14.

[0029] Furthermore, the inner side of the empty groove 14 is symmetrically provided with sliding grooves 17, and the outer side of the movable plate 15 is symmetrically fixedly connected with sliders, which are slidably connected to the sliding grooves 17.

[0030] When cleaning the filter plate, the operator first pulls the drive head 12 to move the drive rod 11, which in turn moves the moving seat 9. The moving seat 9 then moves the brush 10 to wipe the filter plate. The brush 10 is made of flexible rubber, which reduces the risk of damaging the filter screen. Cleaning can be completed simply by pulling the drive head 12, without disassembling the housing 2, which reduces the workload and improves the efficiency. The operator can directly operate the external drive structure to start the self-cleaning process, realizing a self-cleaning mode of external operation and internal cleaning. When the movable seat 9 moves, the guide rod 13 provides an additional support point for the movable seat 9, so that the movable seat 9 can remain stable when moving; When the brush 10 comes into contact with the filter plate, the reaction of the brush 10 will drive the moving plate 15 to move in the slot 14. The movement of the moving plate 15 will squeeze the spring 16, causing the spring 16 to compress and generate elastic potential energy. The elastic potential energy of the spring 16 will maintain a certain pressure between the brush 10 and the filter plate, thereby improving the cleaning effect of the brush 10. When the movable plate 15 moves, the slider and the groove 17 provide guidance for the movable plate 15, so that the movable plate 15 maintains the correct movement trajectory when moving.

[0031] Reference Figure 1 , Figure 2 and Figure 5 The protective mechanism includes a protective seat 18 set on the top of the outer shell 2 of the oxygen outlet pipe 6. Connecting plates 19 are symmetrically fixedly connected to the outer side of the protective seat 18. A rotating shaft is fixedly connected between the two connecting plates 19. A protective plate 20 is rotatably connected to the outer side of the rotating shaft. The protective plate 20 overlaps with the protective seat 18. A buffer pad 21 is fixedly connected to the bottom of the protective plate 20.

[0032] After the oxygen concentrator 4 is used, the operator rotates the protective plate 20 on the rotating shaft so that the protective plate 20 is rotated above the protective seat 18, thereby protecting the oxygen outlet pipe 6 and reducing the risk of dust and insects entering the oxygen concentrator 4 through the oxygen outlet pipe 6. When the protective plate 20 is rotated above the protective seat 18, the buffer pad 21 is made of rubber. Rubber has a certain degree of flexibility, which can buffer the impact force and reduce noise and component wear.

[0033] Working principle: When using oxygen concentrator 4, connect the power supply to oxygen concentrator 4, then complete the parameter preset through the control panel, start oxygen concentrator 4, its internal fan starts to work, generating negative pressure suction, and introduces outside air into oxygen concentrator 4 through the air intake grille body 5 on the outside of the housing 2. Then oxygen concentrator 4 performs gas separation, and the prepared high-purity oxygen is delivered to oxygen outlet pipe 6 through the air outlet of oxygen concentrator 4. The operator pulls the drive head 12 to drive the drive rod 11 to move, and the moving seat 9 moves. The moving seat 9 drives the brush 10 to wipe the filter plate. The brush 10 is made of flexible rubber, which can reduce the risk of damaging the filter screen. Cleaning can be completed by simply pulling the drive head 12.
