DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example:

[0023] like Figures 1 to 5 As shown, this embodiment provides a silent and energy-saving oxygen concentrator, including a box body 1, a vertical plate 2 is provided in the middle of the box body 1, the vertical plate 2 divides the internal space of the box body 1 into a front chamber 3 and a rear chamber 4, an oxygen production component 5 is provided in the front chamber 3, and an air compressor 6 is provided in the rear chamber 4. A water storage tank 7 is provided on the upper and lower sides of the box body 1, and a water pipe 8 is provided on the front and back sides of the vertical plate 2. The water pipe 8 is repeatedly bent from bottom to top, and the upper and lower ends of the water pipe 8 are respectively connected to the corresponding water storage tank 7. A submersible pump 9 is provided at the bottom of the lower water storage tank 7, and the outlet of the submersible pump 9 is connected to the lower end of the water pipe 8 on one side. The air outlet of the air compressor 6 is connected to the air pipe A1. 0 is connected to the air inlet at the lower end of the oxygen production component 5. The back of the box body 1 is provided with an air extraction port 11 at the bottom and a nitrogen exhaust port 12 at the top. The air extraction port 11 and the nitrogen exhaust port 12 are respectively equipped with a muffler 13. The outer end port of the muffler 13 is detachably connected to a filter plate 14. The muffler 13 of the air extraction port 11 is connected to the air inlet of the air compressor 6 through the air supply pipe B15, and the muffler 13 of the nitrogen exhaust port 12 is connected to the nitrogen outlet of the oxygen production component 5 through the air supply pipe C16. An oxygen exhaust port 17 is provided on the front of the box body 1. The oxygen exhaust port 17 is connected to the oxygen outlet of the oxygen production component 5 through the air supply pipe D18. The inner wall of the box body 1 is equipped with sound insulation cotton 19.

[0024] By using the silencer 13 and the sound insulation cotton 19 in combination, the noise generated when the gas enters and exits and when the air compressor 6 and the oxygen production component 5 are in operation is suppressed, the quiet performance is improved, and the user experience is improved; when the air compressor 6 draws air from the outside and the oxygen production component 5 discharges nitrogen to the outside, the silencer 13 is used to reduce the noise generated by the air extraction port 11 and the nitrogen exhaust port 12 when the gas passes through, and the sound insulation cotton 19 installed on the inner wall of the box 1 absorbs the noise generated when the air compressor 6 and the oxygen production component 5 are in operation, increasing the difficulty of the noise spreading to the outside through the box 1. Specifically, the oxygen production component 5 includes a pair of molecular sieve towers and a valve mechanism matched therewith. The two molecular sieve towers alternately discharge oxygen and discharge nitrogen to achieve the effect of continuous oxygen output.

[0025] By using the water tank 7, water pipe 8 and submersible pump 9 in combination, the heat in the box body 1 that is difficult to diffuse due to the obstruction of the sound insulation cotton 19 is conducted to the water tank 7 located outside the box body 1, thereby improving the heat dissipation speed and reducing the risk of overheating; the cooling water in the water tank 7 located on the lower side can be pumped into the water tank 7 on the upper side under the action of the submersible pump 9, and the cooling water in the water tank 7 on the upper side can flow downward into the water tank 7 on the lower side under the action of its own gravity, forming a flow circulation of cooling water. When the cooling water flows through the water pipe 8, the heat in the box body 1 can be conducted to the cooling water through the water pipe 8. When the cooling water flows into the water tank 7, the heat in the cooling water diffuses to the outside through the water tank 7, thereby achieving the effect of diffusing the internal heat to the outside. The shape of the water pipe 8 is to increase the length of the cooling water movement path in the box body 1, thereby improving the effect of conducting heat in the box body 1 to the cooling water.

[0026] Furthermore, a valve 20 is provided at the upper end of the water delivery pipe 8 , and an observation window 21 for observing the liquid level inside the water tank 7 is provided on the front side of the water tank 7 .

[0027] To ensure optimal heat exchange within the water pipe 8, the cooling water is allowed to remain in the water tank 7 for a certain period of time to dissipate heat before flowing back into the water pipe 8. For the upper water tank 7, this is done by manipulating the valve 20 at the upper end of the water pipe 8. For the lower water tank 7, this is done by turning the submersible pump 9 on and off. An observation window 21 allows staff to check the cooling water levels in both water tanks 7, preventing either tank from being too low in cooling water, which could affect heat dissipation efficiency.

[0028] Furthermore, a connecting rod 22 is connected between the water tank 7 and the box body 1, and a distance is left between the water tank 7 and the box body 1 for air flow to pass through.

[0029] The connecting rod 22 is used to keep a distance between the water tank 7 and the box body 1, so as to facilitate heat dissipation of the water tank 7.

[0030] Furthermore, a water supply port 23 is provided at the top of the water storage tank 7 on the upper side, and a water discharge port 24 is provided at the bottom of the water storage tank 7 on the lower side. The water supply port 23 and the water discharge port 24 are each provided with a valve 20 .

[0031] The staff can conveniently add water to or reduce water from the water storage tank 7 through the water supply port 23 and the water discharge port 24 . The valve 20 is used to control the opening and closing of the connected water supply port 23 and the water discharge port 24 .

[0032] Furthermore, support columns 25 are evenly arranged on the bottom edge of the box body 1 , reinforcement rods 26 are connected between adjacent support columns 25 , and self-locking universal wheels 27 are provided at the bottom of the support columns 25 .

[0033] With the help of the self-locking universal wheels 27, the box body 1 can be flexibly moved to a predetermined position. When it is necessary to move, the staff unlocks the self-locking universal wheels 27 and pushes the box body 1. When it is necessary to stop, the staff locks the self-locking universal wheels 27. The reinforcing rod 26 is used to increase the strength of the support column 25 connected to it and reduce the risk of the support column 25 being bent.

[0034] Furthermore, a temperature sensor 28 is provided in each of the front chamber 3 and the rear chamber 4 , and the temperature sensor 28 is electrically connected to the submersible pump 9 .

[0035] The temperature inside the box 1 is checked in time by the temperature sensor 28. When the temperature inside the box 1 exceeds the predetermined maximum safe temperature, the submersible pump 9 receiving the control signal of the temperature sensor 28 is started, allowing cooling water to flow through the water pipe 8, thereby accelerating the heat dissipation and reducing the temperature inside the box 1 back to a safe temperature range.

[0036] The working principle and use process of this utility model:

[0037] Before oxygen production begins, staff add an appropriate amount of cooling water to the water tank 7 and install cleaned filter screens 14 on the outer ports of the two mufflers 13. To produce oxygen, the air compressor 6 and oxygen production assembly 5 are started. Outside air enters the housing 1 through the air extraction port 11. Driven by the air compressor 6, the air then enters the oxygen production assembly 5. Oxygen is separated from the air and sent to the oxygen discharge port 17, which is typically connected to equipment that uses oxygen. The remaining nitrogen and other gases are then sent to the nitrogen discharge port 12 for discharge to the outside. The cooling water below is pumped upward by the pump, while the cooling water above flows downward under its own gravity. The flowing cooling water transfers heat from the housing 1 to the upper and lower water tanks 7 and dissipates it to the outside, reducing the risk of overheating within the housing 1. After oxygen production is complete, the air compressor 6, oxygen production assembly 5, and submersible pump 9 are shut down. If the cooling water has exceeded its specified usable life, the cooling water in the water tank 7 can be drained through the drain port 24.

[0038] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
