Description

Technical Field

[0001] The invention relates to the technical field of air treatment equipment, in particular to an oxygen generator with an air purification function. Background Art

[0002] Tourists or short-term workers in plateau areas are prone to hypoxia due to their inability to adapt to the low concentration of air in the plateau. In the prior art, a diffuse oxygen generator is usually used to alleviate the indoor hypoxia. The oxygen generator mainly inhales gas from the surrounding air, compresses the gas through a compressor to increase the concentration of the gas, and the compressed gas passes through a molecular sieve filter. The molecular sieve can selectively adsorb impurities such as nitrogen and allow oxygen to pass through. Finally, the oxygen-rich gas is released into the surrounding environment to increase the oxygen content. The oxygen generator can provide a stable and pure oxygen supply, help improve respiratory function, and alleviate the discomfort symptoms caused by hypoxia. However, the existing oxygen generator does not have the function of air purification when in use, which is not convenient for people to use. Therefore, a solution is proposed in the prior art.

[0003] For example, Chinese patent publication number CN221131428U discloses an oxygen concentrator with air purification function, including a shell, an oxygen concentrator is fixedly connected to the inner bottom of the shell, a negative ion generator is fixedly connected to the air outlet of the oxygen concentrator, a three-way pipe is fixedly connected to the air outlet of the negative ion generator, a filter cartridge is fixedly connected to the end of the three-way pipe away from the negative ion generator, a sealing plate is movably connected to the back of the shell, a connecting rod is fixedly connected to the bottom of the sealing plate, a filter plate is fixedly connected to the bottom of the connecting rod, a fixed sleeve is fixedly connected to the back of the shell, and a threaded rod is connected to the internal thread of the fixed sleeve. The oxygen concentrator with air purification function can greatly increase the oxygen content and negative ion content in the device.

[0004] There are still some shortcomings in the above application. The negative ion generator in the device is set at a low position, and the activity range of negative ions is limited. The air at higher places is difficult to purify, which affects the air purification effect. At the same time, the negative ion generator usually uses high-voltage ionization to generate negative ions. When generating negative ions, an equal amount of positive ions will also be generated. A large number of positive ions will be accompanied by static electricity. The closer to the device, the higher the concentration of charged ions. When the device is used for a long time close to the wall, a large amount of charged particles and dust are easily attached to and accumulated on the wall, polluting the wall and making it difficult to clean.

[0005] Therefore, it is necessary to provide an oxygen concentrator with air purification function to solve the above technical problems. Summary of the invention

[0012] As a further solution of the present invention, a pulling rope is connected between the blocking plate and the inner support rod, and two ends of the pulling rope are respectively fixed to the outer side surface of the blocking plate and the side surface of the inner support rod.

[0013] As a further solution of the present invention, the two baffle plates are respectively located on one side of the air inlet and the outlet. When the two baffle plates are folded, the air inlet and the outlet are covered by the two baffle plates.

[0014] As a further solution of the present invention, a guide tube is fixed between the inner wall of the shell and the outer wall of the built-in tube, and the pulling rope slides through the guide tube.

[0015] As a further solution of the present invention, a storage cavity is provided at the bottom of the shell, and a bottom moving assembly is provided in the storage cavity, which is transmission-connected to the inner support rod and allows the whole to be conveniently moved and transferred.

[0016] As a further solution of the present invention, a convex rib arranged along the length direction of the connecting rod is fixed on the side surface of the connecting rod, and a guide groove slidably matched with the convex rib is formed at the bottom end of the built-in cylinder.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The inner support rod is driven upward by the setting of the call-out component, so that the inner support rod is moved out of the built-in cylinder, thereby placing the negative ion generator at a higher position, so that the negative ions generated by the negative ion generator can be fully combined with the air from a higher position, and harmful substances in the air can be inactivated and removed from top to bottom, thereby increasing the activity range of negative ions, purifying the air more fully and effectively, and effectively improving the air purification effect.

At the same time, the expansion angle of the barrier component can be adjusted by extending the inner support rod to different degrees, thereby adjusting the isolation distance between the outer shell and the wall. In a relatively narrow space, the separation distance between the outer shell and the wall can be reduced to meet the use requirements of different occasions.

[0021] 3. When the entire device is not in use, the inner support rod is driven downward and retracted into the built-in tube through the provided call-out assembly, so that the negative ion generator is stored in the top of the built-in tube, thereby effectively reducing the volume of the entire device, reducing the occupied space, and facilitating storage and transfer. At the same time, the downward-moving inner support rod drives the barrier assembly to automatically fold, thereby automatically folding and storing the barrier assembly, and synchronously completing the folding of the barrier assembly, further reducing the overall volume. At the same time, the folded barrier assembly can cover and protect the air inlet and outlet, preventing dust and impurities in the external environment from entering the interior of the shell through the air inlet and outlet, effectively improving the protection of the entire device and extending the service life of the entire device.

[0022] 4. During use, when the inner support rod is extended upward, the bottom moving assembly automatically retracts to the bottom of the outer shell, so that the outer shell is stably placed, effectively improving the placement stability of the entire device, and allowing the entire device to automatically switch between stable placement and convenient movement, combining stable placement and convenient movement functions, effectively improving overall practicality.

The side wall of the shell 4 is fixed with a control panel 7 electrically connected to the negative ion generator 10, the oxygen concentrator 12 and the servo motor 103. The negative ion generator 10, the oxygen concentrator 12 and the servo motor 103 are controlled by the control panel 7. The shell 4 The bottom of the air conditioner is provided with a storage chamber 8, and a bottom moving assembly 2 is provided in the storage chamber 8, which is transmission-connected with the inner support rod 9 and enables the whole to be conveniently moved and transferred; when in use, the negative ion generator 10 and the oxygen concentrator 12 are controlled by the control panel 7 to work, and the negative ion generator 10 generates and releases negative ions into the air when working, and the negative ions actively capture harmful substances in the air, inactivate microorganisms, bacteria and viruses in the air and on the surface of objects, thereby purifying the indoor air; the oxygen concentrator 12 is provided with an air compressor, a molecular sieve adsorption tower, a gas exchanger, an oxygen concentration monitor and other accessories The air in the indoor environment can enter the oxygen generator 12 through the air inlet 15 and the air inlet pipe 14 in sequence. The air compressor in the oxygen generator 12 compresses the air and sends it to the molecular sieve adsorption tower. Through the selective adsorption of the molecular sieve, impurities such as nitrogen are separated and only oxygen is allowed to pass through. Subsequently, the pure oxygen is further processed by the gas exchanger to increase the concentration of the output oxygen. The produced oxygen is transported to the discharge port 16 through the discharge pipe 13, and is discharged through the discharge port 16 to diffuse into the indoor environment, thereby increasing the oxygen content in the indoor space and providing a comfortable indoor environment.

[0039] When in use, the inner support rod 9 is driven to move upward by the call-out assembly 1, so that the inner support rod 9 is moved out of the built-in cylinder 11, thereby placing the negative ion generator 10 at a higher position, so that the negative ions generated by the negative ion generator 10 can be fully combined with the air from a higher position, and harmful substances in the air can be inactivated and removed from top to bottom, thereby increasing the activity range of the negative ions, purifying the air more fully and effectively, and effectively improving the air purification effect; in the process of the inner support rod 9 moving upward and extending, the inner support rod 9 triggers the barrier assembly 3 to expand to the outside of the shell 4, thereby effectively isolating the negative ion generator 10 from the air through the barrier assembly 3. The outer shell 4 and the wall are separated to ensure that the outer shell 4 is always separated from the wall, so as to prevent a large number of charged particles near the outer shell 4 from adhering to the wall and polluting the wall. At the same time, the expansion angle of the barrier component 3 can be adjusted by extending the inner support rod 9 to different degrees, so as to adjust the isolation distance between the outer shell 4 and the wall. In a relatively narrow space, the separation distance between the outer shell 4 and the wall can be reduced to meet the use requirements of different occasions. Furthermore, when the overall device is not in use, the inner support rod 9 is driven by the set call-out component 1 to move down and retract into the built-in cylinder 11, so that negative ions are generated. The device 10 is stored in the top of the built-in cylinder 11, thereby effectively reducing the volume of the entire device, reducing the occupied space, and facilitating storage and transfer. At the same time, the inner support rod 9 that moves downward drives the barrier component 3 to automatically fold, so that the barrier component 3 is automatically folded and stored, and the folding of the barrier component 3 is completed simultaneously, further reducing the overall volume. At the same time, the folded barrier component 3 can cover and protect the air inlet 15 and the exhaust port 16. When not in use, dust and impurities in the external environment are prevented from entering the interior of the housing 4 through the air inlet 15 and the exhaust port 16, effectively improving the protection of the entire device and extending the life of the device. The service life of the whole device; when the inner support rod 9 is moving downward and retracted into the built-in cylinder 11, the inner support rod 9 pushes the bottom moving component 2 to extend from the bottom of the outer shell 4, so that the whole device can be conveniently moved through the set bottom moving component 2, which is convenient for transfer and use. When in use, when the inner support rod 9 is moving upward and extending, the bottom moving component 2 automatically retracts to the bottom of the outer shell 4, so that the outer shell 4 is stably placed, effectively improving the placement stability of the whole device, so that the whole device can automatically switch between stable placement and convenient movement, and has both stable placement and convenient movement functions, effectively improving the overall practicality.

The separation distance between the outer shell 4 and the wall can be reduced in a relatively narrow space to meet the usage requirements of different occasions. When not in use, the inner support rod 9 moves downward and retracts to make the pulling rope 301 in a relaxed state, so that under the action of its own weight, the blocking plate 302 automatically rotates in the opposite direction and folds, that is, the blocking plate 302 is in contact with the outer wall of the outer shell 4, completing the folding of the blocking plate 302 and further reducing the overall volume.

[0042] Further Figure 4 and Figure 7As shown, it is worth explaining in detail that two blocking plates 302 are provided and the two blocking plates 302 are respectively located on two adjacent side surfaces of the four sides of the shell 4; when the shell 4 is located at a corner, the two wall surfaces of the corner are blocked simultaneously by the two blocking plates 302 arranged on two adjacent side surfaces of the four sides of the shell 4, ensuring the effect of preventing charged particles from adhering to the wall surface.

[0043] Further Figure 4 and Figure 7 As shown, it is worth explaining in detail that the two baffle plates 302 are respectively located on one side of the air inlet 15 and the exhaust port 16. When the two baffle plates 302 are folded, the air inlet 15 and the exhaust port 16 are covered by the two baffle plates 302; the two folded baffle plates 302 cover and protect the air inlet 15 and the exhaust port 16, and when not in use, dust and impurities in the external environment are prevented from entering the interior of the housing 4 through the air inlet 15 and the exhaust port 16, thereby effectively improving the protection of the overall device and extending the service life of the overall device.

The liquid in the cylinder 11 is squeezed, thereby pushing the first piston plate 204 downward in the built-in cylinder 11 through the hydraulic pressure, so that the connecting rod 203 drives the connecting plate 201 to move downward, so that the universal wheel 202 extends from the storage chamber 8 and contacts the ground, so that the entire device can be conveniently moved through the set universal wheel 202, which is convenient for transfer and use. During use, when the inner support rod 9 is in the process of moving upward and extending, under the action of the self-weight of the outer shell 4 and the components inside the outer shell 4, the outer shell 4 moves downward and makes the bottom end of the outer shell 4 contact the ground. At this time, the universal wheel 202 automatically retracts into the storage chamber 8, so that the outer shell 4 is stably placed, effectively improving the placement stability of the overall device, so that the overall device can automatically switch between stable placement and convenient movement, and has both stable placement and convenient movement functions, effectively improving the overall practicality.

In the process of the inner support rod 9 moving upward, the inner support rod 9 pulls the barrier plate 302 through the pulling rope 301. It is flipped and unfolded to the outside of the shell 4, so that the shell 4 and the wall are effectively isolated by the blocking plate 302, ensuring that the shell 4 is always isolated from the wall, and preventing a large amount of charged particles near the shell 4 from adhering to the wall and polluting the wall; when the inner support rod 9 is in the process of moving upward and extending, the hydraulic pressure in the built-in cylinder 11 is released, and under the action of the deadweight of the shell 4 and the components inside the shell 4, the shell 4 moves downward and makes the bottom end of the shell 4 contact with the ground. At this time, the universal wheel 202 automatically retracts into the storage cavity 8, so that the shell 4 is stably placed.

[0047] When not in use, the servo motor 103 drives the driving gear 102 to rotate in the opposite direction, thereby driving the inner support rod 9 to move downward and retract into the inner tube 11, so that the negative ion generator 10 is stored in the top of the inner tube 11, and the inner support rod 9 that moves downward and retracts makes the pulling rope 301 in a relaxed state, so that under the self-weight of the blocking plate 302, the blocking plate 302 automatically rotates in the opposite direction and folds, that is, the blocking plate 302 is in contact with the outer wall of the shell 4, and the blocking plate 302 is folded. The air inlet 15 and the exhaust port 16 are covered; at the same time, the inner support rod 9 drives the second piston plate 205 to move downward in the built-in cylinder 11, so that the liquid in the built-in cylinder 11 is squeezed by the second piston plate 205, and the first piston plate 204 is pushed downward in the built-in cylinder 11 by hydraulic pressure, so that the connecting rod 203 drives the connecting plate 201 to move downward, so that the universal wheel 202 extends from the storage chamber 8 and contacts the ground, so that the entire device can be conveniently moved by the set universal wheel 202, which is convenient for transfer and use.

[0048] Further Figure 6 and Fig.11 As shown, it is worth explaining in detail that a convex rib 206 arranged along the length direction of the connecting rod 203 is fixed on the side surface of the connecting rod 203, and a guide groove slidably adapted to the convex rib 206 is opened at the bottom end of the built-in cylinder 11; during specific operation, the movement of the connecting rod 203 is guided and limited by the cooperation of the set convex rib 206 and the guide groove, thereby improving the stability of the extension and retraction switching of the universal wheel 202.

[0051] In summary: when in use, the inner support rod 9 is driven upward by the set call-out component 1, so that the inner support rod 9 is moved out of the built-in tube 11, thereby placing the negative ion generator 10 at a higher position, so that the negative ions generated by the negative ion generator 10 can be fully combined with the air from a higher position, and harmful substances in the air are inactivated and removed from top to bottom, thereby increasing the activity range of negative ions, purifying the air more fully and effectively, and effectively improving the air purification effect; in the process of the inner support rod 9 moving upward and extending, the inner support rod 9 triggers the barrier component 3 to expand to the outside of the outer shell 4, thereby effectively isolating the outer shell 4 and the wall through the barrier component 3, ensuring that the outer shell 4 is always isolated from the wall, and avoiding a large number of charged particles near the outer shell 4 from adhering to the wall and polluting the wall. When not in use, the inner support rod 9 is driven downward by the set call-out component 1 to retract into the built-in tube 11, so that the negative ion generator 10 is stored in the top end of the built-in tube 11, and the inner support rod that moves downward 9 drives the barrier component 3 to be automatically folded, thereby automatically folding and storing the barrier component 3, and synchronously completing the folding of the barrier component 3, further reducing the overall volume. At the same time, the folded barrier component 3 can cover and protect the air inlet 15 and the exhaust port 16. When not in use, dust and impurities in the external environment are prevented from entering the interior of the shell 4 through the air inlet 15 and the exhaust port 16, effectively improving the protection of the entire device and extending the service life of the entire device; when the inner support rod 9 is in the process of moving downward and retracting into the built-in cylinder 11, the inner support rod 9 pushes the bottom moving component 2 to extend from the bottom of the shell 4, so that the entire device can be conveniently moved through the set bottom moving component 2, which is convenient for transfer and use. When in use, when the inner support rod 9 is in the process of moving upward and extending, the bottom moving component 2 automatically retracts to the bottom of the shell 4, so that the shell 4 is stably placed, effectively improving the placement stability of the entire device, so that both stable placement and convenient movement functions are achieved, and the overall practicality is effectively improved.

The servo motor 103, the control panel 7 and the negative ion generator 10 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.
