Description

Technical Field

[0001] The utility model relates to the technical field of micro-pressure oxygen chamber equipment, in particular to a noise reduction component for a micro-pressure oxygen chamber. Background Technique

[0002] A micro-pressure oxygen chamber is a health care device that supplies rich oxygen after pressurization. As the air pressure in the chamber increases, the partial pressure of oxygen in the air also increases. The physically dissolved oxygen in the blood and tissues increases, the partial pressure of oxygen in the alveoli increases significantly, the oxygen penetration power increases, the blood oxygen content increases, and the blood oxygen diffusion function restores cell vitality, quickly eliminates exercise fatigue, and effectively improves the body's antioxidant capacity.

[0003] Existing micro-pressure oxygen chambers generally use the equipped oxygen generator set to generate oxygen, and then transport it to the micro-pressure oxygen chamber through a gas pipe. Since the oxygen generator set will generate high-frequency vibration and noise, these noises will be transmitted to the micro-pressure oxygen chamber along with the oxygen, thus forming a relatively large noise in the micro-pressure oxygen chamber. Secondly, the oxygen is directly discharged into the micro-pressure oxygen chamber, and the air flow is concentrated and the flow rate is too high, which will also form noise, seriously affecting the product experience. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a noise reduction component for a micro-pressure oxygen chamber to solve the technical problems in the above background technique.

[0005] The technical solution of the utility model is as follows:

[0006] A noise reduction component for a micro-pressure oxygen chamber includes an oxygen generation end noise reduction box and an oxygen chamber end noise reduction box. The opposite surfaces of the oxygen generation end noise reduction box are respectively provided with an air inlet joint A and an exhaust joint; one side surface of the oxygen chamber end noise reduction box is provided with an air inlet joint B, and a plurality of pneumatic mufflers are installed at intervals on the top surface; the exhaust joint and the air inlet joint are connected by an air pipe; steel wool balls are filled in both the oxygen generation end noise reduction box and the oxygen chamber end noise reduction box.

[0007] Further, the air inlet joint A and the exhaust joint are respectively arranged at the diagonals of the opposite surfaces, and the air inlet joint B is arranged at the central position near the bottom side of the oxygen chamber end noise reduction box.

[0008] Further, ear plates are arranged at the rear ends of the left and right sides of the oxygen chamber end noise reduction box, and screw holes are opened on the ear plates.

[0009] The beneficial effects of the utility model are as follows:

[0010] In the utility model, steel wool balls are filled in both the oxygen generation end noise reduction box and the oxygen chamber end noise reduction box. When the oxygen flowing through the steel wool balls with high-frequency vibration causes the steel wool balls to also generate high-frequency vibration, the dense steel wires in the steel wool balls will rub against each other and vibrate independently to convert the vibration energy into heat consumption. The pneumatic mufflers disperse the discharge of oxygen, increase the discharge surface, and reduce the flow rate, thereby avoiding the "hissing" noise. Description of the Drawings

[0014] The following further describes the detailed embodiments of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0015] As Figure 1-2 shown:

[0016] A micro-pressure oxygen storage noise reduction component includes an oxygen generation end noise reduction box 1 and an oxygen storage end noise reduction box 3. The opposite faces of the oxygen generation end noise reduction box 1 are respectively provided with an air inlet joint A 11 and an exhaust joint 12; one side face of the oxygen storage end noise reduction box 3 is provided with an air inlet joint B 31, and a plurality of pneumatic mufflers 4 are installed at intervals on the top surface; the exhaust joint 12 and the air inlet joint are connected by a gas transmission pipe 2; steel wool is filled in both the oxygen generation end noise reduction box 1 and the oxygen storage end noise reduction box 3.

[0017] In order to increase the flow path length of the air flow in the oxygen generation end noise reduction box 1 and the oxygen storage end noise reduction box 3, the air inlet joint A 11 and the exhaust joint 12 are respectively arranged at the diagonals of the opposite faces, and the air inlet joint B 31 is arranged at the center position near the bottom side of the oxygen storage end noise reduction box 3.

[0018] As an optimized solution, ear plates 32 are arranged at the rear ends of the left and right sides of the oxygen storage end noise reduction box 3, and screw holes are provided on the ear plates 32 for convenient installation on the inner wall of the micro-pressure oxygen storage.

[0019] In the present utility model, the oxygen generation end noise reduction box 1 is installed on one side of an external oxygen generation device. The outlet of the oxygen generation device is connected to the air inlet joint A 11, and then oxygen is transported to the oxygen storage end noise reduction box 3 through the gas transmission pipe 2 after passing through the oxygen generation end noise reduction box 1. The oxygen storage end noise reduction box 3 is installed inside the micro-pressure oxygen storage. After the oxygen enters the inside of the oxygen storage end noise reduction box 3, it is dispersed and discharged into the oxygen storage end noise reduction box 3 by the pneumatic mufflers 4.

[0020] Steel wool is filled in both the oxygen generation end noise reduction box 1 and the oxygen storage end noise reduction box 3. There are two sources of noise. The main aspect is that the oxygen discharged from the oxygen generation equipment transmits the working vibration and noise of the oxygen generation equipment. Through the oxygen transmission into the micro-pressure oxygen storage, and the micro-pressure oxygen storage is in a closed state, thus generating very loud noise in the micro-pressure oxygen storage. Secondly, the oxygen is directly discharged from the pipeline into the micro-pressure oxygen storage, with concentrated air flow and too high flow rate, thus generating the "hissing" noise.

[0021] In the present utility model, steel wool is filled in both the oxygen generation end noise reduction box 1 and the oxygen storage end noise reduction box 3. When the oxygen flowing at high frequency vibrates through the steel wool, the steel wool will also generate high-frequency vibration. The dense steel wires in the steel wool will rub against each other and vibrate autonomously to convert the vibration energy into heat consumption. The pneumatic muffler 4 disperses the discharge of oxygen, increases the discharge area, reduces the flow rate, and thus avoids the "hissing" noise.

[0022] The above has described in detail the embodiments of the present utility model in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
