Description
Technical Field
[0001] The present utility model relates to the technical field of oxygen generators, and particularly to an air intake structure of an oxygen generator. Background Art
[0002] An oxygen generator refers to a machine for producing oxygen. When an oxygen generator is in use, impurities contained in the air are filtered and intercepted through a filter cotton provided at the air intake part thereof, so as to ensure that there is no large amount of impurities remaining in the air inhaled into the interior of the oxygen generator, thereby reducing the filtration burden of subsequent filter elements for purifying air. In order to ensure high-quality oxygen production, the filter cotton for primary air filtration should be cleaned once every certain period of application to ensure that the filtering function of the filter cotton is not affected. However, the existing oxygen generator does not have a corresponding reminder function to remind the nursing staff to clean the filter cotton at intervals, and it is also unable to force the nursing staff to clean it at intervals, which has deficiencies. Content of the Utility Model

Through the installation and cooperation of an embedded plug board and an air intake matching notch, the pressing start of an extension board and a timing on-off switch can be synchronously realized, so as to automatically control the timing module to start timing, and the usage time of the oxygen generator is recorded through timing. When the timing value is reached, through signal feedback, a buzzer reminder is realized to remind the nursing staff that the filter cotton that has intercepted impurities in the air for a long time needs to be cleaned to ensure the quality of the incoming air and ensure high-quality oxygen production.

[0007] Further, a set of reminder parts and a set of timing opening and closing switches are fixedly installed on the rear side surface of the inner end of the upper-side embedded notch. The reminder part is a buzzer, and the timing opening and closing switch is a touch switch, and the button end of the timing opening and closing switch faces the front side; when the extension plate is inserted and matched in the embedded notch, the rear end surface of the extension plate is in pressure contact with the button end of the timing opening and closing switch, and at this time the timing opening and closing switch is in the pressed and started state.
[0008] Further, a microcontroller and a timing module electrically connected thereto are provided inside the oxygen generator main body; the reminder part and the timing opening and closing switch are both electrically connected to the microcontroller; the timing value of the timing module is twelve hours; a set of reminder closing switches is fixedly installed on the rear side surface of the inner end of the lower-side embedded notch, and the reminder closing switch is electrically connected to the microcontroller; when the timing opening and closing switch is in the pressed and started state, the timing opening and closing switch feeds back a signal to the microcontroller, and the microcontroller controls the timing module to start timing; when the timing value of the timing module is reached, the timing module feeds back a signal to the microcontroller, and the microcontroller controls the reminder part to start beeping; when the reminder closing switch is in the pressed and started state, the timing opening and closing switch feeds back a signal to the microcontroller, and the microcontroller controls the reminder part to close.
[0009] The present utility provides an air intake structure of an oxygen generator, which has the following beneficial effects:
[0010] Through the installation and matching of the embedded plug board and the air intake matching notch, the present utility can synchronously realize the pressing and starting of the extension plate and the timing opening and closing switch, so as to automatically control the timing module to start timing, and record the use time of the oxygen generator through timing.

[0011] Through the cooperation and installation of the extension plate and the embedded notch, the present utility model can block the reminder off switch used to control the closing of the reminder component in the buzzer startup state. Thus, when realizing the buzzer reminder, it forces the operation of the nursing staff, making it impossible to turn off the reminder component in the buzzer startup state before disassembling and separating the embedded plug board. Through the forced disassembly and separation operation of the embedded plug board, it is convenient for the nursing staff to clean the filter cotton synchronously, ensuring that the filter cotton is cleaned once every certain period of use time to guarantee the quality of the incoming air.

[0027] The working principle of this embodiment:
[0028] When the outside air is inhaled into the oxygen generator main body 1, first, large-volume impurities that may be contained in the inhaled air are filtered and intercepted through the air-permeable filtration opening 201 of the embedded insertion plate 2, and then the air that enters the air intake matching notch 101 through the air-permeable filtration opening 201 is further filtered and intercepted by the filter cotton 4 to intercept and filter the impurities contained in the inhaled air, and the air after double filtration can enter the oxygen generator main body 1 through the air intake matching notch 101.
[0029] When the embedded insert plate 2 is fixedly installed inside the air intake mating notch 101 through the threaded connection and cooperation of the locking bolt 3 with the threaded blind hole 105, at this time, the extension plate 202 that is fitted and inserted inside the embedded notch 103 will press against the button end of the timing on-off switch 107. At this time, the timing on-off switch 107 is in the pressed and started state, and the timing on-off switch 107 gives a feedback signal to the microcontroller 1010. The microcontroller 1010 controls the timing module 109 to start timing. The timing module 109 of this utility model is twelve hours, but it is not limited to this timing value and can be changed and set according to requirements; when the timing value of the timing module 109 is reached, the timing module 109 gives a feedback signal to the microcontroller 1010, and the microcontroller 1010 then controls the reminder 106 that is a buzzer to start beeping, so as to remind the nursing staff through this beeping that they need to clean the filter cotton 4 that has intercepted impurities in the air for a long time;
[0030] For the closing operation of the reminder 106 in the beeping start state, it is necessary to disassemble the locking bolt 3 along the threaded blind hole 105, and then pinch the pinch plate 203 to separate the embedded insert plate 2 from the air intake mating notch 101, exposing the part of the embedded notch 103 covered by the extension plate 202. At this time, the nursing staff can press the reminder off switch 108 located in the lower-side embedded notch 103, so as to give a signal feedback to the microcontroller 1010 through it, and control the reminder 106 to close through the microcontroller 1010. Through this design, a mandatory operation can be implemented for the nursing staff, so that the reminder 106 in the beeping start state cannot be closed before disassembling and separating the embedded insert plate 2, and through the mandatory disassembly and separation operation of the embedded insert plate 2, it is convenient for the nursing staff to synchronously clean the filter cotton 4.
