Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen concentrators, and particularly relates to a temperature control device used in an oxygen concentrator. Background Art

[0002] By using the adsorption performance of molecular sieves and physical principles, a large-displacement oil-free compressor is used as the power to separate nitrogen and oxygen in the air, and finally obtain high-concentration oxygen. This type of oxygen generator produces oxygen quickly and has a high oxygen concentration. It is suitable for oxygen therapy and oxygen health care for all kinds of people. The operating temperature of molecular sieves is generally 5-35℃, so the oxygen production effect is best when the air is within this temperature range;

[0003] For example, the Chinese patent publication number CN220232311U proposes “a gas temperature control device for an oxygen concentrator, comprising an oxygen concentrator body and a temperature control chamber, an air intake pipe is arranged outside the temperature control chamber, an air intake fan is arranged on the air intake pipe, and an end of the air intake pipe close to the temperature control chamber is respectively connected with a first connecting pipe and a second connecting pipe at the upper and lower ends thereof…”;

[0004] Although the above device maintains the air temperature between 5-35°C, such a temperature control device separates the heating space from the cooling space, resulting in a larger required volume and the need to be used separately from the oxygen generator. For this reason, we propose a temperature control device that can integrate heating and cooling together to reduce the occupied space. Utility Model Content

[0005] The utility model provides a temperature control device used in an oxygen concentrator, which solves the problems in the prior art.

[0008] The heat dissipation pipe is inserted and connected in the heat dissipation device. A heating element is attached to the inner wall of the heating pipe to heat the air entering the pipe. A detection element is also provided at the air inlet of the heat dissipation pipe to detect the temperature entering the pipe.

[0009] When the temperature detected by the detection component is lower than 5°C, the air is heated when passing through the heating tube. If the detected temperature is higher than 35°C, the air is cooled when passing through the heat dissipation tube. The heated / cooled air is discharged along the tail of the gas pipeline to the molecular sieve for adsorption.

[0010] Furthermore, the detection component includes an air inlet nozzle arranged at the air inlet of the heat dissipation pipe, and a temperature sensor is also arranged at the tail of the air inlet nozzle for detecting the air temperature of the inlet pipe.

[0011] Furthermore, a connecting pipe is provided between the heat dissipation pipe and the heating pipe.

[0012] Furthermore, the tail of the heating tube is connected through an exhaust pipe for exhausting air.

[0013] Furthermore, the heating element includes a resistance wire arranged on the inner wall of the heating tube.

[0014] Furthermore, the heat dissipation device includes multiple groups of heat dissipation fins, which are pressed together, and the heat dissipation pipes are inserted into the heat dissipation fins in a serpentine shape. A mounting plate is also provided above the heat dissipation fins, and two groups of heat dissipation fans are installed on the inner side of the mounting plate for air cooling the heat dissipation fins.

[0015] Furthermore, the connecting device includes connecting plates arranged on the heat dissipation fins at both ends, and a clamping plate for clamping the heating tube is also integrally arranged between the two groups of connecting plates.

[0016] Furthermore, grooves are provided on the inner side of the clamping plate corresponding to the heating tube, and rubber pads are fixedly provided on the inner side of the grooves.

[0017] After adopting the above technical solution, the beneficial effects of the utility model are:

[0018] In the utility model, by arranging the heating tube and the heat dissipation tube together, the air can be cooled down by the heat dissipation tube and the heat dissipation device, or heated up by the resistance wire in the heating tube, so that the air enters the molecular sieve within a suitable range. The temperature control device has a smaller volume and can be directly installed inside the oxygen generator for use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment: A temperature control device for an oxygen concentrator comprises a gas pipeline 10 and a heat dissipation device, wherein a connecting device is provided between the heat dissipation device and the gas pipeline 10;

[0028] like Figure 1 As shown, the gas pipeline 10 includes a heat dissipation pipe 101 for air to enter, and a heating pipe 102 is connected through one end of the heat dissipation pipe 101. Figure 3-4 As shown, a resistance wire 105 is fixedly arranged on the inner wall of the heating tube 102, and the resistance wire 105 can heat the air in the heating tube 102. An air inlet nozzle 104 is also inserted into the air inlet of the heat dissipation tube 101;

[0029] like Figure 5 As shown, a temperature sensor 107 is also embedded inside the tail end of the air inlet nozzle 104, which is used to detect the temperature of the air entering from the air inlet nozzle 104. When the air temperature is lower than 5°C, the resistance wire 105 is started to heat the air in the heating tube 102. When the temperature is between 5°C and 35°C, the air is output along the air pipeline 10 without heating or cooling. When the temperature is higher than 35°C, the heat dissipation device needs to be used to cool the air.

[0030] The whole process of air entering and exiting the pipeline is that the air first enters the pipeline along the heat dissipation pipe 101, passes through the heat dissipation pipe 101 to the heating pipe 102, and finally is discharged along the exhaust pipe 106 at the tail of the heating pipe 102. The air should be cooled / heated to a suitable temperature (i.e., between 5-35°C) in the gas pipeline 10 before being discharged;

[0031] like Figure 1-2 How does the heat dissipation device shown cool down the air in the gas pipeline 10? Specifically, the heat dissipation device includes heat dissipation fins 20. Multiple groups of heat dissipation fins 20 are pressed together. A heat dissipation pipe 101 is also connected to one end of the heating pipe 102. The heat dissipation pipe 101 is inserted into the heat dissipation fins 20 in a serpentine shape. When the temperature is higher than 35°C, the heating pipe 102 will not heat the air. The air enters the heat dissipation pipe 101 along the heating pipe 102. The heat dissipation pipe 101 is a copper pipe. The heat dissipation pipe 101 is also fixedly connected to the heat dissipation fins 20. The heat in the pipe is dissipated through the heat dissipation fins 20. In order to enhance the heat dissipation effect, a mounting plate 21 is also provided at the upper end of the heat dissipation fins 20. Two groups of heat dissipation fans 22 are also provided on the mounting plate 21 to perform air cooling and heat dissipation on the heat dissipation fins 20. When the temperature drops to between 5°C and 35°C, the air is output to the molecular sieve through the gas pipeline 10 for oxygen production.

[0032] A connecting pipe 103 is also provided between the heat dissipation pipe 101 and the heating pipe 102;

[0033] like Figure 1 As shown, in order to facilitate the fixing of the position of the heating tube 102, a connecting plate 30 is provided on the heat dissipation fins 20 at both ends, and a clamping plate 31 is fixedly connected to the end of the connecting plate 30, so that all the heating tubes 102 are clamped in the clamping plate 31, and grooves are opened on the inner side of the clamping plate 31 corresponding to the heating tube 102, and a rubber pad 32 is fixedly installed in the groove, so that the heating tube 102 can remain fixedly connected to the clamping plate 31.

[0034] The temperature control device mentioned above adopts existing control software or other control devices, so its principle is not described in detail here, and the appropriate temperature can be set according to needs.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
