[0002] An oxygen concentrator is a device that produces oxygen; its core function is to produce oxygen using air separation technology.

[0003] When an oxygen concentrator produces oxygen, if the generated oxygen contains high levels of moisture, it will reduce the purity and quality of the oxygen, posing safety hazards and health risks to users. Therefore, a monitoring and alarm device is needed for real-time monitoring to allow for timely countermeasures. Existing oxygen concentrator moisture monitoring and alarm devices only monitor the moisture content in the oxygen at key gas path locations. Excessive moisture content at the oxygen concentrator's air inlet can cause premature wear of internal components such as filters and adsorbents, thus shortening the oxygen concentrator's lifespan.

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. Example 1

[0025] Please see Figures 1-7 This utility model discloses a moisture monitoring and alarm device for an oxygen concentrator, including a housing 1 and a chassis 2 located below the housing 1, and also includes a filter assembly 3, an air compressor 4, a heat dissipation assembly 5, a separation assembly 6, and a monitoring assembly 7, wherein:

[0026] The outer side of the housing 1 is equipped with a control console 11, the control console 11 is equipped with an air intake pipe 111, and the bottom surface of the chassis 2 is equipped with several universal wheels 21.

[0027] Please refer to the appendix. Figure 5 The filter assembly 3 includes an air intake filter element 31, with an external air cylinder 75 fixed to the top of the air intake filter element 31. The bottom of the air intake filter element 31 is connected to an adsorption bottle 32, which is connected to one side of the air compressor 4. The other side of the air compressor 4 is connected to a condenser pipe 51, which passes through the bracket 22. Specifically, the air intake filter element 31 removes solid particles and liquid water from the air to ensure air cleanliness and protect downstream equipment from damage. The adsorption bottle 32 further adsorbs impurities in the air and enters the air compressor 4 for compression and separation of oxygen and nitrogen.

[0028] The monitoring component 7 includes a gas chamber 71, a moisture analysis probe 72 is installed on the top of the gas chamber 71, the moisture analysis probe 72 is electrically connected to a PLC module 73, the PLC module 73 is electrically connected to an alarm light 74, and the alarm light 74 is installed on the top surface of the outer side of the housing 1.

[0029] Please refer to the appendix. Figure 6 The gas chamber 71 includes an outer gas chamber 711 and an inner gas chamber 712. One side of the outer gas chamber 711 is connected to an outer gas cylinder 75, and the bottom of the inner gas chamber 712 is connected to a high-pressure valve 61. The high-pressure valve 61 is connected to a gas storage tank 62. Specifically, the high-pressure valve 61 can be controlled and adjusted by the flow meter adjustment knob 112, thereby controlling the speed of oxygen release from the oxygen pipe 65.

[0030] In this embodiment, the moisture analysis probe 72 monitors the air in the external air chamber 711, converts the detected moisture content signal into an electrical signal, and transmits it to the PLC module 73. The PLC module processes the received signal and determines whether the moisture content exceeds the standard. If the moisture content exceeds the standard, an alarm is triggered by the alarm light 74. Example 2

[0031] Based on the above embodiment 1, please refer to the appendix. Figure 2 , Figure 3 , Figure 4 as well as Figure 7 The control panel 11 is equipped with a flow meter adjustment knob 112 and a start button 113, and a bracket 22 is welded to the top surface of the chassis 2.

[0032] The air compressor 4 is fixedly connected to the chassis 2 by screws. The chassis 2 below the air compressor 4 is provided with several heat dissipation holes 23 that connect to the outside.

[0033] The bracket 22 is provided with a heat dissipation groove 52, and a small fan 53 is fixedly installed in the heat dissipation groove 52. The small fan 53 is located below the condenser pipe 51. Specifically, the small fan 53 blows air into the condenser pipe 51 to cool down the high-temperature compressed gas inside it, so as to avoid high temperature damage to subsequent molecular sieve and other components.

[0034] The separation component 6 includes a solenoid valve 63, which is connected to one end of the condenser tube 51. Two molecular sieves 64 are symmetrically arranged on one side of the support 22. The molecular sieves 64 are connected to the solenoid valve 63. Specifically, the solenoid valve 63 can make the two molecular sieves 64 work alternately, which is convenient for nitrogen removal operation after the molecular sieves 64 become clogged after long-term use.

[0035] The gas storage tank 62 is installed between the molecular sieves 64, which connect the two sides of the gas storage tank 62. One side of the internal gas chamber 712 is connected to the oxygen pipe 65.

[0036] In this embodiment, the separated gas is alternately introduced into the molecular sieve 64 by the solenoid valve 63 to filter out impurities such as nitrogen, and then enters the gas storage tank 62 for storage. The oxygen enters the internal gas chamber 712 after being pressurized by the high-pressure valve 61. The moisture content is monitored by the moisture analysis probe 72, thereby realizing simultaneous internal and external monitoring and alarm.

[0037] The working principle and usage process of this utility model are as follows: First, the device is moved to the predetermined position by using the universal wheels 21 of the chassis 2 and the handle on the box 1. Then, the start button 113 is turned on. After the air compressor 4 is started, it begins to draw air from the inside of the box 1. The air pressure inside the box 1 decreases, and external air is filled by air intake pipe 111. The external air enters the external air cylinder 75 and the air intake filter 31 below it.

[0038] The air entering the external air cylinder 75 then enters the external air chamber 711. The air comes into contact with the moisture analysis probe 72 and its moisture content is monitored in real time. The moisture analysis probe 72 converts the detected moisture content signal into an electrical signal and transmits it to the PLC module 73. The PLC module processes the received signal and determines whether the moisture content exceeds the standard. If it does, it controls the alarm light to light up and issues an alarm signal, thus completing the monitoring and alarm of the external air moisture content and taking countermeasures as soon as possible to avoid excessive wear and tear on the adsorption bottle 32 and the air intake filter 31 due to prolonged heavy work.

[0039] Air entering through the intake filter 31 is filtered to remove solid particles and liquid water, ensuring air cleanliness and protecting downstream equipment from damage. It then passes through the adsorption bottle 32 to further adsorb impurities before entering the air compressor 4. After compression, oxygen is separated from nitrogen and other gases, and then enters the condenser 51. A small fan 53 blows air into the condenser 51 to cool the high-temperature compressed gas inside, preventing damage to downstream components such as the molecular sieve. The separated gas is alternately passed through the molecular sieve 64 via the solenoid valve 63 to filter out impurities such as nitrogen, and then enters the gas storage tank 62 to obtain pure oxygen. After pressure regulation by the high-pressure valve 61, the oxygen enters the internal gas chamber 712. The moisture content is monitored using the moisture analysis probe 72, enabling simultaneous internal and external monitoring and alarm. Once the oxygen in the internal gas chamber 712 passes the monitoring, it can be released from the oxygen pipe 65 for use.
