Description

Technical Field

[0001] This utility model relates to the technical field of oxygen generator equipment, specifically a portable environmental conditioning device based on air oxygen generation. Background Technology

[0002] As people's living standards continue to improve, they are paying more and more attention to health. Human health is inseparable from oxygen. In some special environments, conditions or situations where natural oxygen is insufficient to meet people's normal needs, supplemental oxygen inhalation or emergency oxygen inhalation has become an important means for people to maintain their health.

[0003] Existing technology CN222489505U discloses a novel portable oxygen concentrator, including a body and a fixing strap. An extension strap is embedded and fixedly disposed on one side of the body. A fixing mechanism is provided between the extension strap and the fixing strap to facilitate fixing the position of the extension strap and the fixing strap. A storage mechanism is provided on one side of the body to facilitate storing the fixing strap. The storage mechanism includes a box, a cover plate, a perforation, a compression component, a movable shaft, a baffle, and a torsion spring. The box is fixed to one side of the body. By wrapping the fixing strap around the outside of the movable shaft, the fixing strap is pulled out during use. The fixing strap drives the movable shaft to rotate, and the torsion spring is tightened. Then, the screw is rotated, causing the screw to move along the screw hole until it compresses the outside of the fixing strap, thereby fixing the position of the fixing strap. By fixing the fixing strap to one side of the extension strap, the device can be carried by the fixing strap.

[0004] However, the following shortcomings still exist in actual use: when fixing the fixing strap, the screw needs to be rotated continuously, which is inefficient; and the fixing method of pressing the outside of the fixing strap by the screw is prone to damage after repeated use, affecting the service life of the fixing strap.

[0005] Based on this, a portable environmental conditioning device based on air oxygen generation is now available, which can eliminate the drawbacks of existing devices. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-6 As shown, a portable environmental conditioning device based on air oxygen generation includes a housing 100. A fixing box 101 is fixedly connected to the outer end of the housing 100. A rotating shaft 102 is rotatably connected within the fixing box 101. One end of a spring-loaded spring 103 is fixedly connected to the rotating shaft 102, and the other end of the spring-loaded spring 103 is connected to the fixing box 101. A fixing strap 104 is fixedly connected to the rotating shaft 102 and wound around the outer end of the rotating shaft 102. A fixing mechanism for fixing the fixing strap 104 is provided on the rotating shaft 102. The fixing box 101 has an unlocking mechanism. The device includes an oxygen-generating module inside the housing 100 and a heat dissipation component on the housing 100. When the device needs to be carried, pulling the fixing strap 104 causes the rotating shaft 102 to rotate, which in turn causes the spring 103 to twist and store energy. The fixing mechanism secures the fixing strap 104 for easy carrying. When the fixing strap 104 needs to be retracted, the fixing is released by the unlocking component, and the fixing strap 104 returns to its original position under the twist of the spring 103. Continuous oxygen production is achieved through the oxygen-generating module, and the heat dissipation component ensures the working performance of the oxygen-generating module.

[0025] In this embodiment, as Figure 5 and Figure 6 As shown, the fixing mechanism includes a gear 201, which is fixedly connected to the rotating shaft 102. A locking block 202 is connected to the gear 201 and is slidably connected in a corresponding groove 203 on the fixing box 101. One end of the locking block 202 is fixedly connected to a spring 204, and the other end of the spring 204 is fixedly connected to the inner wall of the groove 203. When the fixing band 104 is pulled out, the rotating shaft 102 drives the gear 201 to rotate. The locking block 202 slides in the groove 203 and compresses the spring 204 through the unlocking component. When the fixing band 104 is pulled to a suitable length, the locking block 202 resets and engages in the tooth groove of the gear 201 under the elastic force of the spring 204, thereby fixing the rotating shaft 102 and fixing the position of the fixing band 104.

[0026] In one embodiment, such as Figure 6As shown, the unlocking component includes a trapezoidal fixing block 301, which is fixedly connected to one end of the locking block 202 located within the slide groove 203. The inclined surface of the trapezoidal fixing block 301 is engaged with a trapezoidal moving block 302, which is slidably connected within the slide groove 203. One end of the trapezoidal moving block 302 is fixedly connected to a second spring 303, and the other end of the second spring 303 is connected to the inner wall of the slide groove 203. The end of the trapezoidal moving block 302 away from the second spring 303 is fixedly connected to a pressing block 304. Pressing block 304 extends out of slide groove 203. When it is necessary to retract the fixing band 104, press pressing block 304. Pressing block 304 drives trapezoidal moving block 302 to slide in slide groove 203 and compress spring 2 303. The inclined surface of trapezoidal moving block 302 presses the inclined surface of trapezoidal fixing block 301, causing trapezoidal fixing block 301 to drive locking block 202 to disengage from the tooth groove of gear 1 201, releasing the fixation of rotating shaft 102. Under the elastic force of spring spring 103, rotating shaft 102 rotates in the opposite direction, winding and retracting fixing band 104. The operation is convenient.

[0027] In one embodiment, such as Figure 4As shown, the oxygen generation module includes an air inlet 401 located on the side of the housing 100. The air inlet 401 is connected to an air filter 402, which is connected to the input of an air compressor 403 via a guide pipe. The output of the air compressor 403 is connected to the input of a condenser assembly 404. The condenser assembly 404 is existing technology and will not be described in detail here. The output of the condenser assembly 404 is equipped with a solenoid valve 405, which is connected to a first molecular sieve tower 406 and a second molecular sieve tower 407 via guide pipes. The first molecular sieve tower 406 and the second molecular sieve tower 407 are connected to an oxygen storage tank 408 via a second solenoid valve 410. The output of the oxygen storage tank 408 is equipped with a pressure regulating valve 409. Nitrogen gas is provided on the first molecular sieve tower 406 and the second molecular sieve tower 407. The nitrogen outlet 411 is equipped with a pressure relief valve 412. The solenoid valve 405, solenoid valve 410, and pressure relief valve 412 are electrically connected to the controller. Outside air enters through the air inlet 401, passes through the air filter 402 to remove impurities, and then enters the air compressor 403 to be compressed. The compressed air enters the condenser assembly 404 for cooling and drying to remove moisture. Then, the controller controls the opening and closing of the solenoid valve 405, so that the dried air alternately enters the first molecular sieve tower 406 and the second molecular sieve tower 407. The molecular sieves adsorb nitrogen from the air and produce oxygen. The oxygen enters the oxygen storage tank 408 for storage through the solenoid valve 410. The stored oxygen is output for user use after the pressure is regulated by the pressure regulating valve 409. The adsorbed nitrogen is discharged through the pressure relief valve 412 at the nitrogen outlet 411, realizing continuous oxygen production and meeting the user's oxygen intake needs in different environments.

[0028] In one embodiment, such as Figure 3 As shown, the heat dissipation component includes a heat dissipation hole 501, which is located on the housing 100. A cooling fan 502 is fixedly connected to the heat dissipation hole 501, and a filter screen 503 is connected to the heat dissipation hole 501 through a removable unit. During operation, the oxygen generation module generates heat. The cooling fan 502 accelerates the airflow inside the housing 100, and the heat is discharged through the heat dissipation hole 501, thereby achieving heat dissipation inside the housing 100. The filter screen 503 can prevent external dust and other impurities from entering the housing 100 through the heat dissipation hole 501, thus avoiding impurities from affecting the working performance of the oxygen generation module.

[0029] In one embodiment, such as Figure 3As shown, the easily detachable unit includes two movable blocks 601, which are slidably connected in corresponding movable slots 602 on the housing 100. The filter screen 503 has a corresponding slot 603 on each movable block 601. One end of a spring 604 is fixedly connected to each movable block 601, and the other end of the spring 604 is connected to the inner wall of the movable slot 602. A push rod 605 is connected to each movable block 601, extending out of the movable slot 602 to mount the filter screen. At step 503, push the push rod 605 to move the movable block 601 within the movable slot 602 and compress the spring 604, placing the filter screen 503 at the heat dissipation hole 501. Release the push rod 605, and under the elastic force of the spring 604, the movable block 601 resets and locks into the slot 603 of the filter screen 503, thus fixing the filter screen 503. To disassemble, push the push rod 605 again to disengage the movable block 601 from the slot 603, and the filter screen 503 can be removed. The operation is simple and convenient.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the end of the fixing strap 104 away from the rotating shaft 102 is fixedly connected to the buckle 701, and the side of the box 100 away from the fixing box 101 is fixedly connected to the fixing block 702. The fixing block 702 is provided with a fixing groove 703 corresponding to the buckle 701. After the fixing strap 104 is pulled out, the buckle 701 is inserted into the fixing groove 703 of the fixing block 702, and the device can be carried by the fixing strap 104.

[0031] In one embodiment, such as Figure 2 As shown, four support feet 800 are fixedly connected to the lower end of the box 100. The support feet 800 can support the box 100, prevent the bottom of the box 100 from directly contacting the ground, prevent moisture or impurities from the ground from corroding the bottom of the box 100, and also facilitate the stability of the box 100 when placing equipment.

[0032] The above embodiments disclose a portable environmental conditioning device based on air oxygen generation. Pressing the pressing block 304 causes the trapezoidal moving block 302 to slide within the slide groove 203, compressing the second spring 303. The inclined surface of the trapezoidal moving block 302 presses against the inclined surface of the trapezoidal fixing block 301, causing the trapezoidal fixing block 301 to retract the locking block 202 back into the slide groove 203, pulling the fixing belt 104. The fixing belt 104 drives the rotating shaft 102 to rotate, causing the spring 103 to twist and store elastic potential energy. Simultaneously, the gear 201 on the rotating shaft 102 rotates. After the fixing strap 104 is pulled to the appropriate length, the pressing block 304 is released. Under the elastic force of the spring 204, the locking block 202 resets and engages with the tooth groove of the gear 201, thereby fixing the rotating shaft 102 and fixing the position of the fixing strap 104. The buckle 701 engages with the fixing groove 703 of the fixing block 702, and the device can be carried by the fixing strap 104. During oxygen production, outside air enters through the air inlet 401, is filtered by the air filter 402 to remove impurities, and then enters the air compressor 403 to be compressed. The compressed air then enters the condenser. Component 404 is cooled and dried to remove moisture. Then, the controller controls the opening and closing of solenoid valve 405, causing the dried air to alternately enter the first molecular sieve tower 406 and the second molecular sieve tower 407. The molecular sieves adsorb nitrogen from the air, producing oxygen. The oxygen enters the oxygen storage tank 408 via solenoid valve 410 for storage. The stored oxygen is then pressure-regulated by pressure regulating valve 409 before being supplied to users. The adsorbed nitrogen is discharged through pressure relief valve 412 at nitrogen outlet 411, achieving continuous oxygen production to meet users' oxygen intake needs in different environments. The hot air fan 502 accelerates the airflow inside the housing 100, and the heat is discharged through the heat dissipation hole 501 to dissipate heat inside the housing 100. The filter screen 503 prevents external dust and other impurities from entering the housing 100 through the heat dissipation hole 501, thus avoiding impurities from affecting the working performance of the oxygen generation module. When it is necessary to clean or replace the filter screen 503, push the push rod 605. The push rod 605 drives the moving block 601 to slide in the moving groove 602, so that the moving block 601 disengages from the slot 603 of the filter screen 503, and the filter screen 503 can be removed for cleaning or replacement.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
