Technical Field
[0001] The utility model relates to a water tank structure of an oxygen generator, belonging to the technical field of the water tank of an oxygen generator. Background Art
[0002] The existing oxygen generators on the market mainly use the principle of pressure swing adsorption technology to generate oxygen. This scheme uses a compressor to pressurize air, and the pressurized air passes through a molecular sieve to separate nitrogen in the air, thereby generating oxygen with a higher concentration. In order to keep the oxygen output by the oxygen generator appropriately humid, the high-concentration oxygen will first pass through the water tank and then reach the oxygen outlet of the oxygen generator. The role of the water tank is to humidify the high-concentration oxygen and cool the oxygen. The water tank is generally detachably arranged on the oxygen generator and needs to be filled with water irregularly.
[0003] The Chinese utility model patent with the authorization announcement number of CN220046748U discloses an oxygen generator with a humidifying function. The oxygen generator is equipped with a water storage tank, and the oxygen is humidified through the water storage tank. However, this scheme has a relatively complex structure, and the water level of the water storage tank cannot be confirmed during night use. Summary of the Utility Model
[0004] In order to overcome the problems existing in the prior art, the utility model provides a water tank structure of an oxygen generator, which is beneficial to determining the water level of the water storage tank even during night use. The specific technical solutions are as follows.
[0005] A water tank structure of an oxygen generator includes a housing and a water tank, and is characterized in that: a water tank installation groove is arranged on the housing, and the water tank is accommodated in the water tank installation groove; a light guiding member is arranged at the bottom of the water tank installation groove, and a light emitting member is arranged closely adjacent to the light guiding member; the water tank installation groove is provided with a first observation window above the light guiding member, a part of the water tank corresponding to the first observation window is made of a transparent material, and the housing is provided with a second observation window corresponding to the first observation window.
[0006] By adopting the above technical solution, when the oxygen generator is used at night, the light emitted by the light emitting member shines from the bottom of the water tank installation groove to the bottom of the water tank, making the bottom position of the water tank highly bright. Due to the different refractive indices of water and air to light, the water level height and air flow condition in the water tank can be clearly observed through the first observation window and the second observation window.
[0007] Furthermore, the housing includes a front shell, a rear shell and a top cover, and the water tank installation groove is located on the top cover. Arranging the water tank installation groove on the top cover facilitates the removal or insertion of the entire water tank. The water tank installation groove is located between the front shell and the rear shell, and the second observation window is located on the front shell or the rear shell.
[0008] Further, the water tank includes a water tank chamber and a water tank cover. The water tank chamber includes a water storage cavity and an air inlet cavity, and the air inlet cavity is communicated with the water tank air inlet. The water storage cavity and the air inlet cavity are separated by a rib plate, and ventilation holes are provided at the bottom of the rib plate to communicate the water storage cavity and the air inlet cavity. The light guide member is located below the water storage cavity. Oxygen enters the air inlet cavity through the air inlet, and then enters the water storage cavity through the ventilation holes. The water in the water storage cavity humidifies the oxygen. Preferably, the water tank chamber is made of a transparent material. Preferably, when the water tank is accommodated in the water tank installation groove, the water tank cover is flush with the top cover. This makes the appearance of the entire oxygen generator more regular and beautiful.
[0009] Further, an air outlet interface is provided on the water tank cover, and the air outlet interface is communicated with the water storage cavity. The water in the water storage cavity humidifies the oxygen, and the oxygen is output to an external pipeline through the air outlet interface.
[0010] Further, a water filling port is provided on the water tank cover, and a sealing plug is movably provided on the water filling port. By providing a water filling port on the water tank cover, water can be added without opening the entire water tank cover.
[0011] Further, a handle is also provided on the water tank cover. The handle is beneficial for taking out the entire water tank from the water tank installation groove.
[0012] In the present utility model, by providing a lighting structure at the bottom of the water tank, it is convenient for users to observe the flow of oxygen through the ventilation holes and the water level in the water storage cavity of the water tank in a dark environment. In addition, the water tank is located on the top cover, making it more convenient to take out and place. Description of the Drawings

Detailed implementation manner
[0019] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0020] See Figures 1 - 5 , an oxygen generator water tank structure, including a housing 1 and a water tank 2, the housing 1 includes a front housing 1.1, a rear housing 1.2 and a top cover 1.3, and the top cover 1.3 is located between the front housing 1.1 and the rear housing 1.2; as Figure 2 shown, the water tank mounting groove 3 is located on the top cover 1.3, and a part of the top cover 1.3 is recessed downward to form the water tank mounting groove 3, and the water tank 2 is accommodated in the water tank mounting groove 3. Setting the water tank mounting groove 3 on the top cover 1.3 facilitates the removal or insertion of the entire water tank 2.
[0021] As Figure 2 , Figure 5 shown, a light guide member 4 is provided at the bottom of the water tank mounting groove 3, and a light emitting member 5 is provided close to the light guide member 4, the light emitting member 5 is located below the light guide member 4, and the light guide member 4 allows the light emitted by the light emitting member 5 to enter the water tank 2; the water tank mounting groove 3 is provided with a first observation window 3.1 above the light guide member 4, and the corresponding part of the water tank 2 to the first observation window 3.1 is made of a transparent material, and the housing 1 is provided with a second observation window 1.4 corresponding to the first observation window 3.1, and the second observation window 1.4 is located on the front housing 1.1. Among them, the light guide member 2 is made of a material capable of guiding light, preferably made of a light-transmitting material. The first observation window 3.1 and the second observation window 1.4 can be made of a transparent material window, or can be directly provided with a hollowed window for easy observation.
[0022] Adopting the above technical solution, when the oxygen generator is used at night, the light emitted by the light emitting member 5 shines from the bottom of the water tank mounting groove 3 to the bottom of the water tank 2, making the bottom position of the water tank 2 bright. Due to the different refractive indices of water and air to light, the water level height and air flow condition (bubble condition) in the water tank 2 can be clearly observed through the first observation window 3.1 and the second observation window 1.4.
[0023] As Figure 3 , Figure 4As shown in the figure, the water tank 2 includes a water tank chamber 2.1 and a water tank cover 2.2. The water tank chamber 2.1 includes a water storage cavity 2.1.1 and an air inlet cavity 2.1.2. The air inlet cavity 2.1.2 is communicated with the water tank air inlet 2.3. The water storage cavity 2.1.1 and the air inlet cavity 2.1.2 are separated by a rib plate 2.1.3. A ventilation hole 2.1.4 is provided at the bottom of the rib plate 2.1.3, and the ventilation hole 2.1.4 communicates the water storage cavity 2.1.1 and the air inlet cavity 2.1.2. The light guide member 4 is located below the water storage cavity 2.1.1. Oxygen in the molecular sieve (not shown) is transported to the water tank air inlet 2.3 through a pipeline, enters the air inlet cavity 2.1.2 through the water tank air inlet 2.3, and then the oxygen enters the water storage cavity 2.1.1 through the ventilation hole 2.1.4.

Preferably, when the water tank 2 is accommodated in the water tank installation groove 3, the water tank cover 2.2 is flush with the top cover 1.3. This makes the appearance of the entire oxygen generator more regular and beautiful. When the water tank 2 is installed in the water tank installation groove 3, the water tank air inlet 2.3 will be hermetically connected to the upstream pipeline or interface to prevent oxygen leakage. A one-way valve (not shown) can be installed in the ventilation hole 2.1.4 that communicates the water storage cavity 2.1.1 and the air inlet cavity 2.1.2 to prevent the water in the water storage cavity 2.1.1 from entering the air inlet cavity 2.1.2. Of course, a one-way valve can also be not provided. Even if there is water in the air inlet cavity 2.1.2, the air pressure in the air inlet cavity 2.1.2 will send the water back into the water storage cavity 2.1.1. Among them, the top of the rib plate 2.1.3 is hermetically connected to the water tank cover 2.2 to maintain a certain pressure in the air inlet cavity 2.1.2.
[0024] An air outlet interface 2.2.1 is provided on the water tank cover 2.2, and the air outlet interface 2.2.1 is communicated with the water storage cavity 2.1.1.

[0025] A water filling port (not shown) is provided on the water tank cover 2.2, and a sealing plug 2.2.2 is movably provided on the water filling port. Removing the sealing plug 2.2.2 allows water to be added to the water storage cavity 2.1.1.
[0026] A handle 2.2.3 is also provided on the water tank cover 2.2. The handle 2.2.3 is beneficial for taking out the entire water tank 2 from the water tank installation groove 3.
