Description

Technical Field

[0001] This utility model relates to the field of controller technology, and more specifically to a controller for remotely controlling an oxygen generator. Background Technology

[0002] An oxygen concentrator is a machine that produces oxygen using air separation technology or chemical reactions. It performs a series of physical transformations on air, including compression, separation, and distillation, to generate high concentrations of oxygen; or it utilizes the decomposition of drugs through a catalyst to form oxygen. Oxygen concentrators can provide oxygen to patients with cardiovascular and cerebrovascular diseases and respiratory illnesses, such as myocardial infarction, cerebral thrombosis, chronic bronchitis, and emphysema. They can also provide oxygen to patients suffering from heatstroke, carbon monoxide poisoning, drug poisoning, and other conditions requiring oxygen therapy; and can provide oxygen to pregnant women, the elderly, or those experiencing hypoxia due to impaired cardiopulmonary function. They are also suitable for relieving fatigue and restoring bodily functions after strenuous physical or mental exertion. Furthermore, they can be used for oxygen supply in small and medium-sized hospitals, clinics, and health stations in remote areas, as well as in sanatoriums, home oxygen therapy facilities, sports training centers, and high-altitude military stations. The oxygen concentrator controller provides manual control for staff.

[0003] For example, an oxygen generator controller with prior art publication number CN216623008U can provide different oxygen concentration options according to preset oxygen concentrations. This avoids the energy consumption caused by continuous oxygen supply in the prior art to a certain extent, reduces the operating time of the oxygen generator, and can slow down the aging of the equipment to a certain extent, thus protecting the equipment itself. It also prevents the problem of excessively high ambient oxygen content caused by continuous oxygen supply in existing oxygen generators and avoids the potential health hazards to users, thereby improving the safety of the equipment during use.

[0004] Existing oxygen concentrator controllers typically use RS485 or CAN bus for communication with the oxygen concentrator, requiring a four-core cable. This places high demands on on-site operators and is prone to wiring errors. Therefore, this invention provides a flexible and user-friendly controller for remotely controlling oxygen concentrators. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a controller for remotely controlling an oxygen concentrator. By setting a dedicated bus chip on the main control board, and using two core wires to achieve power supply and communication between the main control board and the oxygen concentrator, the two core wires do not need to distinguish polarity and can be connected arbitrarily during field wiring, ensuring reliable power supply and communication functions. It has the advantages of flexible wiring and convenient use, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a controller for remotely controlling an oxygen generator, comprising a bottom shell, a main control board fixedly disposed inside the bottom shell, a display screen connected to the top of the main control board, a detachable top cover fixedly disposed on the top of the bottom shell, an opening on the top of the top cover, the display screen disposed inside the opening, two interfaces fixedly disposed on the main control board, each interface having a core wire connected inside, a wire management assembly disposed inside the bottom shell, the wire management assembly comprising a mounting plate fixedly disposed on the inner wall of the bottom of the bottom shell, two winding rods rotatably connected to the top of the mounting plate, both winding rods being disposed below the main control board, and two core wires respectively wound around the two winding rods.

[0007] In a preferred embodiment, two fixing components are fixedly provided at the front end of the bottom shell. The fixing components include two symmetrically distributed sleeves, and clamping blocks are slidably connected inside the sleeves. The two clamping blocks cooperate to clamp the core wire to prevent the core wire from automatically loosening and affecting the neatness.

[0008] In a preferred embodiment, a compression spring is connected between the clamping block and the inner wall of the sleeve. Each clamping block is fixed with a pull rod on the side away from the core wire. One end of the pull rod passes through the compression spring and the sleeve in sequence and extends to the outside of the sleeve. The compression spring pushes the clamping block to move out of the sleeve. The two clamping blocks clamp the core wire under the elastic force of the two compression springs, thereby improving the stability of the core wire.

[0009] In a preferred embodiment, two turntables extend through the bottom of the bottom shell, and the top of the turntables extends through the bottom shell and is fixed to the bottom of the winding rod. The turntables facilitate the user's manual rotation of the winding rod to wind up the core wire.

[0010] In a preferred embodiment, heat dissipation holes are provided on both sides of the bottom shell to facilitate heat dissipation of the main control board. Filter plates are fixedly installed inside both heat dissipation holes to block dust and impurities in the air, preventing dust and impurities from entering the controller and affecting heat dissipation.

[0011] In a preferred embodiment, a clamping plate is connected to the bottom of the base shell. The clamping plate is located on the outside of the two turntables and can be clamped to the side of the bed, the headboard, or other locations, so that the user can easily pick up and put down the controller at any time, thus realizing convenient control of the oxygen concentrator.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model sets a dedicated bus chip on the main control board and uses two core wires to realize the power supply and communication connection between the main control board and the oxygen generator. Furthermore, the two core wires do not need to distinguish polarity and can be connected arbitrarily during field wiring, which can ensure reliable power supply and communication functions. It has the advantages of flexible wiring and convenient use.

[0014] 2. The two winding rods inside the bottom shell can be used to wind up the two core wires separately, which can quickly adjust the length of the core wires and store them in an orderly manner, making the overall layout neater. At the same time, the core wires are clamped and fixed by the fixing components, which can play a fixing role. 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] Refer to the instruction manual appendix Figures 1-6 This utility model provides a controller for remotely controlling an oxygen generator, including a bottom shell 1, a main control board 2 fixedly installed inside the bottom shell 1, a display screen 3 connected to the top of the main control board 2, a detachable top cover 4 fixedly installed on the top of the bottom shell 1, an opening 5 on the top of the top cover 4, the display screen 3 being located inside the opening 5, and two interfaces 6 fixedly installed on the main control board 2, each of the two interfaces 6 being connected to a core wire 7.

[0026] The bottom shell 1 is equipped with a cable management assembly 8, which includes a mounting plate 81. The mounting plate 81 is fixed to the inner wall of the bottom of the bottom shell 1. Two winding rods 82 are rotatably connected to the top of the mounting plate 81. The two winding rods 82 are located below the main control board 2. Two core wires 7 are wound around the two winding rods 82 respectively. Two turntables 10 pass through the bottom of the bottom shell 1. The top of the turntables 10 passes through the bottom shell 1 and is fixed to the bottom of the winding rods 82. Two storage slots can be set at the bottom of the bottom shell 1 to store the two turntables 10 respectively, so as to avoid the turntables 10 protruding outward and affecting the fixation of the controller. At the same time, multiple grooves can be set at the bottom of the turntables 10 to facilitate the user to rotate the turntables 10.

[0027] In practical use, the user first connects one end of the two core wires 7 to the interface 6 on the main control board 2. A dedicated bus chip is used on the main control board 2, and the two core wires 7 connect the main control board 2 to the oxygen generator. The oxygen generator acts as the host, providing power to the main control board 2 and transmitting data via the two core wires 7. These two core wires 7 are polarity-insensitive and can be connected arbitrarily during on-site wiring, ensuring effective power supply and communication. The controller can collect oxygen generator operating data in real time and issue control commands, making it very flexible and convenient to use. Furthermore, the controller has two winding rods 82 inside to wind up the two core wires 7 respectively. When wiring is needed, the user can grasp one end of the core wire 7 and pull it off the winding rod 82. Alternatively, the user can rotate the turntable 10 to reverse the winding rod 82, rewinding the excess core wire 7 back onto the winding rod 82, improving aesthetics.

[0028] Refer to the instruction manual appendix Figure 6 The bottom shell 1 is fixedly provided with two fixing components 9 at its front end. The fixing components 9 include two symmetrically distributed sleeves 91. The sleeves 91 are slidably connected with clamping blocks 92. The two clamping blocks 92 cooperate to clamp the core wire 7. Specifically, an arc-shaped groove can be formed on the inner side of the two clamping blocks 92. The core wire 7 is clamped in a ring-like manner by the elastic force of the compression spring 93. The clamping block 92 is connected to the inner wall of the sleeve 91 by the compression spring 93. Each clamping block 92 is fixedly provided with a pull rod 94 on the side away from the core wire 7. One end of the pull rod 94 passes through the compression spring 93 and the sleeve 91 in sequence and extends to the outside of the sleeve 91.

[0029] By setting two clamping blocks 92 to clamp the core wire 7 for fixation, the stability of the core wire 7 can be improved, and the core wire 7 can be prevented from extending too much from the bottom shell 1 due to the rotation of the winding rod 82. When it is necessary to adjust the length of the core wire 7, the user only needs to move the two pull rods 94 in opposite directions to drive the clamping blocks 92 to release the core wire 7. Conversely, when the pull rods 94 are released, the clamping blocks 92 move towards the core wire 7 under the elastic force of the compression spring 93, which can re-clamp the core wire 7 to achieve the fixation function.

[0030] like Figure 2 As shown, heat dissipation holes 11 are provided on both sides of the bottom shell 1, and filter plates 12 are fixedly installed inside the two heat dissipation holes 11. The heat dissipation holes 11 facilitate the heat dissipation of the main control board 2, while the filter plates 12 can block dust and impurities in the air and prevent dust and impurities from entering the controller and affecting heat dissipation.

[0031] The bottom of the base shell 1 is connected to a clamping plate 13, which is located on the outside of the two turntables 10. The clamping plate 13 makes it convenient for users to place the controller on the side or head of the bed, so that users can quickly take the controller and adjust the oxygen machine.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
