[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, an oxygen production device 10 is provided, including an adsorption unit (not shown), a compressor 100 and a recovery unit 200. The adsorption unit is provided with an exhaust port for discharging the analyzed gas. The compressor 100 is provided with a heat dissipation chamber 110. The recovery unit 200 is arranged in the heat dissipation chamber 110, and is provided with a recovery chamber 220 having an air inlet 210 and an air outlet (not shown), and the air inlet 210 is connected to the exhaust port.

[0030] When the oxygen production equipment 10 in the above embodiment is in use, the decomposed gas in the adsorption unit enters the recovery chamber 220 through the exhaust port and the air inlet 210, so that the decomposed gas in the recovery chamber 220 can cool down the compressor 100, ensuring that the temperature of the compressor 100 will not be too high after long-term operation, and can maintain an efficient working state, thereby improving the reliability of the oxygen production equipment 10 and improving the utilization rate of the decomposed gas.

[0031] It should be noted that the adsorption unit refers to a container filled with an adsorbent or a molecular sieve. The desorbed gas refers to the gas desorbed by the adsorbent or the molecular sieve after it reaches a saturated state, mainly nitrogen.

[0032] The adsorption unit may be configured as any adsorption structure for adsorption oxygen production in the prior art. Specifically in this embodiment, the compressor 100 is configured as an air compressor.

[0033] like Figure 3As shown, further, the compressor 100 is further provided with a heat dissipation port 120 communicating with the heat dissipation cavity 110, and the air outlet is communicated with the heat dissipation port 120. In this way, the analyzed gas in the recovery cavity 220 and the gas in the heat dissipation cavity 110 can jointly purge the heat dissipation port 120 of the compressor 100, ensuring that there is no debris blockage at the heat dissipation port 120 and extending the service life of the compressor 100.

[0034] Specifically in this embodiment, heat dissipation fins in heat transfer cooperation with the compressor 100 are installed at the heat dissipation port 120. In this way, the analyzed intake air can accelerate the heat dissipation efficiency of the heat dissipation fins, thereby increasing the heat dissipation efficiency of the compressor 100, ensuring that the temperature of the compressor 100 does not become too high after long-term operation, and improving the reliability of the oxygen generation device 10.

[0035] As Figure 3 and Figure 4 shown, optionally, the oxygen generation device 10 further includes an exhaust air duct 300, and the exhaust air duct 300 is communicated with the heat dissipation port 120. In this way, the exhaust air duct 300 can guide the gas in the heat dissipation cavity 110 and the analyzed gas in the recovery cavity 220 to the outside, reducing the noise of the oxygen generation device 10.

[0036] As Figure 3 shown, specifically in this embodiment, the heat dissipation port 120 is provided at the top of the compressor 100. In this way, the resistance encountered by the gas in the heat dissipation cavity 110 and the analyzed gas in the recovery cavity 220 during the discharge process is reduced. While ensuring that the gas in the heat dissipation cavity 110 and the analyzed gas in the recovery cavity 220 can be smoothly discharged, the airflow noise is also reduced.

[0037] Among them, the number of the recovery members 200 can be flexibly adjusted according to actual usage needs. The recovery member 200 can be a recovery box, a recovery tank, a recovery pipe or other recovery structures.

[0038] As Figure 3 shown, optionally, the number of the recovery members 200 is at least one, and each recovery member 200 is installed in the heat dissipation cavity 110. Each air inlet 210 is communicated with the air outlet, and each air outlet is communicated with the heat dissipation port 120. In this way, by increasing the number of the recovery members 200, the analyzed gas is more evenly distributed in the heat dissipation cavity 110, ensuring that the temperature of the compressor 100 does not become too high after long-term operation, and enabling it to maintain a high-efficiency working state, improving the reliability of the oxygen generation device 10.

[0039] In one embodiment, the oxygen generation device 10 further includes a first connecting pipe. One end of the first connecting pipe is communicated with the air outlet, and the other end is communicated with the heat dissipation port 120. In this way, the analyzed gas in the first connecting pipe can also dissipate heat from the compressor 100, ensuring that the temperature of the compressor 100 does not become too high after long-term operation, and enabling it to maintain a high-efficiency working state, improving the reliability of the oxygen generation device 10.

[0040] As Figure 3 shown, in one embodiment, the oxygen generation device 10 further includes a second connecting pipe 400. One end of the second connecting pipe 400 communicates with the air inlet 210, and the other end communicates with the exhaust port. In this way, the analysis gas in the second connecting pipe 400 can also dissipate heat from the compressor 100, ensuring that the temperature of the compressor 100 will not be too high after long-term operation, and enabling it to maintain an efficient working state, thereby improving the reliability of the oxygen generation device 10.

[0041] It should be noted that the analysis gas discharged from the exhaust port is a low-temperature gas. The analysis gas in the first connecting pipe can exchange heat with the gas in the heat dissipation cavity 110 through the first connecting pipe. The analysis gas in the second connecting pipe 400 can exchange heat with the gas in the heat dissipation cavity 110 through the second connecting pipe 400. The analysis gas in the recovery cavity 220 can exchange heat with the gas in the heat dissipation cavity 110 through the recovery member 200.

[0042] As Figure 1 and Figure 3 shown, optionally, a connecting flange 500 is provided at one end of the second connecting pipe 400 away from the recovery cavity 220, and the connecting flange 500 communicates with the exhaust port. In this way, the exhaust port can communicate with the second connecting pipe 400 through the connecting flange 500, ensuring the reliability of the sealed connection while improving the convenience of assembling the oxygen generation device 10.

[0043] In one embodiment, the air inlet 210 and the air outlet are respectively located on opposite sides of the recovery cavity 220. In this way, the recovery cavity 220 can buffer the analysis gas, so that the flow rate of the analysis gas at the air outlet can be kept stable, thereby ensuring stable heat dissipation of the compressor 100 and improving the reliability of the oxygen generation device 10.

[0044] In one embodiment, the oxygen generation device 10 further includes a heat exchange member, which is installed on the outer wall of the recovery member 200 and is in heat transfer cooperation with the recovery member 200. In this way, the heat exchange member can accelerate the heat exchange rate between the analysis gas in the recovery cavity 220 and the gas in the heat dissipation cavity 110, increasing the heat dissipation performance of the compressor 100 and improving the reliability of the oxygen generation device 10.

[0045] Among them, the heat exchange member can be set as heat exchange fins, heat exchange strips or other heat exchange structures.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0049] In the present application, unless otherwise clearly specified and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0050] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0051] It should also be understood that when interpreting the connection relationship or position relationship of elements, although not explicitly described, the connection relationship and position relationship are interpreted to include an error range, and this error range should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "about", "approximate" or "substantially" can mean within one or more standard deviations, which are not defined herein.

[0052] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0053] The above embodiments only represent several implementation manners of this application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
