Description

Technical Field

[0001] This utility model relates to a water tank, specifically an oxygen generator water tank, and belongs to the technical field of oxygen generator water tanks. Background Technology

[0002] The water tank of an oxygen concentrator is the core component of its humidification system. It is responsible for storing and humidifying oxygen, ensuring that the output oxygen is moist and comfortable, and avoiding dry gas irritating the respiratory tract. Oxygen concentrators separate oxygen from the air through molecular sieves, membrane separation, or water electrolysis technology, but the output oxygen is usually dry. The water in the tank (distilled water or cooled boiled water is recommended) can humidify the oxygen, making it closer to the humidity of the human respiratory tract, improving the comfort of oxygen inhalation, and is especially suitable for people with respiratory tract sensitivities or those who inhale oxygen for a long time.

[0003] However, the interior of the water tank of current oxygen concentrators is usually just a hollow water cavity, with an oxygen inlet pipe and an oxygen outlet pipe on the outer shell. There is a water inlet on the top of the outer shell. Since there is no mechanism to guide oxygen and water flow inside the outer shell, oxygen and water are only separated by a rectangular partition. Oxygen and water directly enter the interior of the water tank. When oxygen and water pass through the structural channels, it is difficult to avoid right angles or narrow areas. The turbulence of airflow and water flow generates noise, affecting the comfort of users. At present, the water inlet and oxygen inlet of oxygen concentrators are on the same side. The oxygen is in direct vertical contact with the liquid surface. The contact area between oxygen and water is small, and the oxygen wet slip rate is low, which affects the comfort of users. Utility Model Content

[0004] The purpose of this utility model is to provide an oxygen generator water tank to solve the above problems. By setting a baffle inside the outer shell of the oxygen generator water tank to allow oxygen and water to pass through, water and oxygen are prevented from entering the water tank directly and vertically, reducing the noise generated by oxygen and water entering the water tank. The design of the air inlet flowing parallel to the liquid surface avoids turbulence from damaging the humidification effect and improves the user's comfort.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: an oxygen generator water tank, comprising a bottom shell and a top shell fastened to the bottom shell, a sealing plate sandwiched between the top shell and the bottom shell, a water inlet mechanism, an oxygen inlet pipe, and an oxygen outlet provided on the bottom shell, an oxygen outlet pipe provided on the sealing plate, a partition one provided inside the bottom shell, an air passage formed between the partition one and the inner wall of the bottom shell, the air passage communicating with the oxygen inlet pipe, a partition two provided inside the bottom shell opposite to the partition one, an entry door formed between the partition two and the partition one, and a partition three provided inside the bottom shell, a water passage formed between the partition three and the partition one.

[0006] Preferably, the end of the partition at the oxygen inlet pipe is arc-shaped, and the partition opposite to the end of the oxygen inlet pipe is arranged parallel to the inner wall of the bottom shell.

[0007] Preferably, the second partition has an L-shaped structure, and the side of the first partition and the side of the second partition are located on the same plane.

[0008] Preferably, the third partition has an arc-shaped structure, and the distance between the bottom of the third partition and the bottom of the first partition is less than the distance between the top of the third partition and the top of the first partition.

[0009] Preferably, the bottom of the top shell has four rectangular locking posts, and the bottom shell has four rectangular locking holes, with the locking posts engaging inside the locking holes.

[0010] Preferably, the water inlet mechanism includes a water inlet, the end of the bottom shell is provided with a water inlet, the water inlet is connected to a water channel, and a sealing plug is provided on the water inlet.

[0011] Preferably, the sealing plate is provided with a liquid level tube, which is embedded in a hole on the top shell, and the oxygen outlet tube passes through another hole on the top shell.

[0012] Preferably, the bottom of the bottom shell is provided with two positioning posts facing each other.

[0013] Preferably, the two positioning posts are at the same height as the oxygen inlet pipe, and the two positioning posts are arranged in a triangle with the oxygen inlet pipe.

[0014] The beneficial effects of this utility model are as follows: Water is added to the water tank through the water inlet mechanism. Because the third baffle has an arc-shaped structure and the distance between its bottom and the bottom of the first baffle is less than the distance between its top and bottom, this design facilitates the smooth flow of water from the inlet to the bottom of the third baffle, and the noise is relatively low when adding water. When the oxygen generator is working, oxygen enters the water tank through the oxygen inlet pipe. The setting of the first baffle at the oxygen inlet pipe allows the oxygen to enter the interior of the bottom and top shells more smoothly, reducing noise. After the oxygen enters, it circulates through the air passage formed between the first baffle and the inner wall of the bottom shell. The oxygen then enters the water surface through the inlet gate formed between the first baffle and the second baffle, which has an L-shaped structure. The side of the first baffle and the side of the second baffle are on the same plane. This design helps the oxygen to enter the water surface smoothly and come into contact with the water. The horizontal setting of the inlet gate and the liquid surface facilitates full contact between the oxygen and the liquid surface, making the oxygen more thoroughly wetted and making the user's breathing more comfortable. The oxygen is humidified after full contact with the water. At the same time, the design of the first baffle reduces the noise of the air intake. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figures 1-6 As shown, the oxygen generator water tank includes a bottom shell 1 and a top shell 2 that is fastened to the bottom shell 1. A sealing plate 8 is sandwiched between the top shell 2 and the bottom shell 1. A water inlet mechanism 6, an oxygen inlet pipe 3, and an oxygen outlet 11 are provided on the bottom shell 1. An oxygen outlet pipe 4 is provided on the sealing plate 8. A partition 12 is provided inside the bottom shell 1. An air passage 13 is formed between the partition 12 and the inner wall of the bottom shell 1. The air passage 13 is connected to the oxygen inlet pipe 3. A partition 2 14 is provided inside the bottom shell 1, which is opposite to the partition 12. An entry door 15 is formed between the partition 2 14 and the partition 12. A partition 3 16 is provided inside the bottom shell 1. A water passage 17 is formed between the partition 3 16 and the partition 12.

[0019] As a technical optimization of this utility model, the end of the partition 12 located at the oxygen inlet pipe 3 is arc-shaped. The partition 12 facing away from the oxygen inlet pipe 3 is arranged parallel to the inner wall of the bottom shell 1, which facilitates the entry of oxygen into the interior of the bottom shell 1 and the top shell 2, making the oxygen entry smoother.

[0020] As a technical optimization of this utility model, the second partition 14 has an L-shaped structure, and the side of the first partition 12 and the side of the second partition 14 are located on the same plane, so that oxygen enters the water surface through the inlet door 15 between the first partition 12 and the second partition 14.

[0021] As a technical optimization of this utility model, the partition 3 16 has an arc-shaped structure, and the distance between the bottom of the partition 3 16 and the bottom of the partition 1 12 is less than the distance between the top of the partition 3 16 and the top of the partition 12. This facilitates the flow of water from the inlet 602 to the bottom of the partition 3 16, and reduces the amount of oxygen at the oxygen outlet, allowing the oxygen to fully contact the water and making the discharged oxygen more slippery.

[0022] As a technical optimization of this utility model, the bottom of the top shell 2 is provided with four rectangular locking posts 9, and the bottom shell 1 is provided with four rectangular locking holes 10. The locking posts 9 are fastened into the inside of the locking holes 10, thereby fastening the top shell 2 and the bottom shell 1 together and fixing the sealing plate 8.

[0023] As a technical optimization of this utility model, the water inlet mechanism 6 includes a water inlet 602. The end of the bottom shell 1 is provided with a water inlet 602. The water inlet 602 is connected to the water channel 17. A sealing plug 601 is provided on the water inlet 602 to enable water to be added from the water inlet 602. The sealing plug 601 blocks the water inlet 602 to prevent water leakage.

[0024] As a technical optimization of this utility model, the sealing plate 8 is provided with a liquid level pipe 5, which is embedded in a hole on the top shell 2, and the oxygen outlet pipe 4 passes through another hole on the top shell 2, so as to facilitate observation of the liquid volume between the bottom shell 1 and the top shell 2, add water in time, and reduce the noise of water flow.

[0025] As a technical optimization of this utility model, two positioning posts 7 are provided at the bottom of the bottom shell 1 to increase the levelness of the overall structure, maintain the stability of the liquid level, and avoid backflow caused by insufficient humidification due to too low water level or too high water level.

[0026] As a technical optimization of this utility model, the two positioning posts 7 are at the same height as the oxygen inlet pipe 3, and the two positioning posts 7 and the oxygen inlet pipe 3 are arranged in a triangle to increase the stability of the overall structure.

[0027] When using this utility model, firstly, during the installation of the overall structure, the four locking posts 9 at the bottom of the top shell 2 are accurately aligned and snapped into the four locking holes 10 on the bottom shell 1. Through this snapping method, not only is a stable connection between the top shell 2 and the bottom shell 1 achieved, but the sealing plate 8 located between the two is also fixed, ensuring the stability of the overall structure of the water tank. After the installed water tank is installed on the oxygen generator, the two positioning posts 7 set opposite each other at the bottom of the bottom shell 1 can increase the levelness of the overall structure and maintain the stability of the liquid level.Meanwhile, the two positioning posts 7 are at the same height as the oxygen inlet pipe 3 and are arranged in a triangle, further enhancing the stability of the water tank when placed, preventing shaking or tilting from affecting normal use. Oxygen is introduced through the oxygen inlet pipe 3 and discharged through the oxygen outlet pipe 4. Locate the water inlet 602 at the end of the bottom shell 1 and remove the sealing plug 601. The sealing plug 601 normally blocks the water inlet 602 to prevent water leakage from the water tank. Slowly inject an appropriate amount of water into the water tank through the water inlet 602. The water will flow into the water tank through the water channel 17 connected to the water inlet 602. Because the partition 3 16 has an arc-shaped structure, and the distance between its bottom and the bottom of partition 1 12 is less than the distance between its top and bottom, this design facilitates the smooth flow of water from the water inlet 602 to the bottom of partition 3 16, and the noise during water filling is relatively low. During the water filling process, the water can be easily added through the water inlet 602. The liquid level tube 5, embedded in the hole of the top shell 2 on the sealing plate 8, observes the liquid level in the water tank. When the liquid level reaches a suitable height, water addition is stopped, and then the sealing plug 601 is reinserted into the water inlet 602 to prevent water leakage. A suitable liquid level ensures sufficient contact between oxygen and water, achieving a good humidification effect, while facilitating timely water addition and preventing insufficient humidification due to low water level or backflow due to excessive water level. Then, when the oxygen generator is working, oxygen enters the water tank from the oxygen inlet pipe 3. The end of the baffle 12 located at the oxygen inlet pipe 3 has an arc-shaped structure. The baffle 12 facing away from the oxygen inlet pipe 3 is set parallel to the inner wall of the bottom shell 1. This design allows oxygen to enter the interior of the bottom shell 1 and the top shell 2 more smoothly, reducing noise. After entering, the oxygen flows through the air passage 13 formed between the baffle 12 and the inner wall of the bottom shell 1. The oxygen then flows through the baffle 12 and the L-shaped air passage 13. The oxygen enters the water through the inlet door 15 formed between the partitions 12 and 14. The sides of the partitions 12 and 14 are on the same plane. This design helps the oxygen to enter the water smoothly and come into contact with the water. The horizontal setting of the inlet door 15 and the liquid surface facilitates full contact between the oxygen and the liquid surface, making the oxygen more humid and making the user's breathing more comfortable. After the oxygen comes into full contact with the water, it is humidified. At the same time, the design of the partition 12 reduces the noise of the air intake. Then, the oxygen is discharged from the water tank through the oxygen outlet pipe 4 that passes through the hole 2 in the top shell on the sealing plate 8. The special structure of the partition 3 16 can also reduce the amount of oxygen at the oxygen outlet during the oxygen flow process, so that the oxygen and water have more contact time and ensure that the discharged oxygen is more humid and meets the usage requirements. Finally, the water level in the water tank is observed regularly through the liquid level pipe 5. If the water level is too low, water is added in time according to the above water addition operation to ensure that the water tank can continuously and normally provide humidification function for the oxygen.
