Description

Technical Field

[0001] This utility model relates to the field of oxygen generator technology, and more specifically to a vehicle-mounted portable oxygen generator. Background Technology

[0002] An oxygen concentrator is a device that produces oxygen using air separation technology or a chemical reaction. The atmosphere at high altitudes is characterized by low pressure and low oxygen. As altitude increases, the air becomes increasingly thinner, causing drivers to experience headaches, dizziness, nausea, vomiting, memory loss, slow reaction time, and a significant decrease in mental and physical efficiency. Therefore, equipping a vehicle with an oxygen concentrator is essential. Existing vehicle oxygen concentrators typically use physical methods to produce oxygen. They convert the car's DC power supply to AC power through a switching inverter. The oxygen concentrator then uses Pressure Swing Adsorption (PSA), utilizing the difference in adsorption capacity of molecular sieves for nitrogen and oxygen in the air, to separate oxygen and nitrogen under pressure changes.

[0003] For example, a portable car oxygen concentrator with prior art publication number CN219564717U reduces the size and weight of the small oxygen concentrator to half of the original, making it lightweight, easy to carry, and space-saving. It is powered by a car power adapter plug and a USB plug, which greatly increases the range of applications.

[0004] However, the existing technology described above still has the following problems in use: Traditional car-mounted oxygen concentrators are connected to the car with bolts. Due to the varying road smoothness in different regions, when the car is driving on bumpy roads, the car body will generate significant vibrations. This can easily cause the bolts to loosen, resulting in the oxygen concentrator colliding with the car body. The vibrations are directly transmitted to the oxygen concentrator, which can easily damage the internal parts and shorten the lifespan of the oxygen concentrator. Based on this, this utility model provides a car-mounted portable oxygen concentrator with shock absorption function. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a vehicle-mounted portable oxygen concentrator. Through the cooperation of a slider and a slide rail, the main body of the oxygen concentrator is supported and installed inside the vehicle. This not only facilitates adjustment of the oxygen concentrator's position but also makes it convenient to carry and use. Furthermore, the shock-absorbing spring and damper between the first and second sleeves work together to provide shock absorption at the bottom of the oxygen concentrator's main body, effectively preventing damage from shaking and extending its service life, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted portable oxygen concentrator, comprising an oxygen concentrator body, with mounting components on both sides of the bottom of the oxygen concentrator body. Each mounting component includes a slider, with two first sleeves connected to the top of each slider and a slide rail at the bottom of each slider. A damper is connected inside each first sleeve, with the top of the damper connected to the bottom of the oxygen concentrator body via a second sleeve. A shock-absorbing spring is connected between the top of the first sleeve and the second sleeve, and the shock-absorbing spring is sleeved on the outside of the damper. Limiting frames are fixedly provided on both outer walls of the oxygen concentrator body, and protective covers are provided inside both limiting frames to protect the side wall structure of the oxygen concentrator body.

[0007] In a preferred embodiment, a rubber sleeve is bonded between the first sleeve and the second sleeve. The rubber sleeve is fitted over the outside of the shock-absorbing spring. The rubber sleeve is soft and can play a dustproof role on the outside of the damper and the shock-absorbing spring.

[0008] In a preferred embodiment, each of the two sliders is threaded with two fastening bolts at its top. The two fastening bolts are located between the two first sleeves. Each of the two slide rails has multiple equally spaced threaded holes at its top. The fastening bolts are threaded to one of the threaded holes. The sliders are fixed by the fastening bolts, which makes it easy for the user to quickly adjust the position of the oxygen concentrator body.

[0009] In a preferred embodiment, multiple equally spaced rectangular fixing holes are provided on both sides of the top of the two slide rails to improve the stability of the slide rails during installation.

[0010] In a preferred embodiment, magnets are fixedly embedded in the bottom walls of both limiting frames, and iron plates are fixedly embedded in the bottom of both protective covers. The iron plates and magnets are magnetically attracted to each other. The magnetic attraction between the magnets and iron plates is used to firmly fix the protective covers in the limiting frames. At the same time, it is convenient for users to quickly disassemble and adjust them.

[0011] In a preferred embodiment, both protective covers have multiple evenly distributed ventilation holes on their outer walls for normal air intake and exhaust of the oxygen generator body.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses the cooperation of slider and slide rail to support and install the main body of the oxygen concentrator in the vehicle, which not only makes it easy to adjust the position of the main body of the oxygen concentrator, but also makes it convenient to carry and use. In addition, the shock-absorbing spring and damper between the first sleeve and the second sleeve cooperate to play a shock-absorbing role at the bottom of the oxygen concentrator main body, effectively preventing the oxygen concentrator main body from being damaged by shaking, thereby extending its service life.

[0014] 2. By installing protective covers on both the left and right sides of the oxygen concentrator, the protective covers can protect the ventilation holes and control panel on the side walls of the oxygen concentrator, preventing objects inside the vehicle from colliding with the control panel and affecting the normal operation of the oxygen concentrator. The use of magnets and iron plates to magnetically attract the protective covers and limit frames improves the firmness of the protective covers and limit frames, and also makes it easy for users to quickly remove the protective covers and use the control panel for adjustment.

[0022] 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.

[0023] Refer to the instruction manual appendix Figures 1-5This utility model provides a portable vehicle-mounted oxygen generator, including an oxygen generator body 1. The oxygen generator body 1 draws in air from outside or inside the vehicle through a built-in fan. The air mainly contains about 78% nitrogen, 21% oxygen, and a small amount of other gases. After pretreatment, the air is pressurized by a compressor pump and sent into an adsorption tower filled with molecular sieves. Under pressure, the molecular sieves preferentially adsorb nitrogen molecules in the air, while oxygen molecules, due to their weak adsorption capacity, will flow out from the other end of the adsorption tower as "unadsorbed gas". The oxygen concentration in the outflowing gas can reach more than 90%, which can be inhaled by the user. When the molecular sieves in the adsorption tower reach saturation in adsorption of nitrogen, the system will automatically reduce the pressure in the adsorption tower. At this time, the adsorption capacity of the molecular sieves for nitrogen decreases, and the previously adsorbed nitrogen will be released and discharged from the device. The molecular sieves recover their adsorption capacity and enter the next cycle. Since the above is the prior art, it will not be described in detail here.

[0024] The oxygen concentrator body 1 has mounting components 2 on both sides of its bottom. Each mounting component 2 includes a slider 21. The top of each slider 21 is connected to two first sleeves 22. The bottom of each slider 21 is provided with a slide rail 23. Each first sleeve 22 is connected to a damper 24. The damper 24 is a device that controls vibration and reduces kinetic energy through damping force. The top of the damper 24 is connected to the bottom of the oxygen concentrator body 1 through a second sleeve 25. A shock-absorbing spring 26 is connected between the top of the first sleeve 22 and the second sleeve 25. The shock-absorbing spring 26 is sleeved on the outside of the damper 24.

[0025] Two fastening bolts 6 are threaded to the top of each of the two sliders 21. The two fastening bolts 6 are located between the two first sleeves 22. The top of each of the two slide rails 23 has multiple equally spaced threaded holes 7. The fastening bolts 6 are threaded to one of the threaded holes 7. The top sides of each of the two slide rails 23 have multiple equally spaced rectangular fixing holes 8.

[0026] In actual use, the user first fixes the two slide rails 23 in the trunk of the car, then puts the two sliders 21 at the bottom of the oxygen concentrator body 1 onto the two slide rails 23 respectively, and then pushes the oxygen concentrator body 1 slowly into place, and then tightens the fastening bolts 6 to fix it. The oxygen concentrator body 1 can then be carried and used. The oxygen concentrator body 1 can provide high-concentration medical oxygen to the people in the car to reduce or alleviate altitude sickness. At the same time, the oxygen concentrator body 1 is protected by the car body and can be used in harsh outdoor environments. Loosening the fastening bolts 6 allows the oxygen concentrator body 1 to be taken out of the car, making it very portable. In addition, when the vehicle is driving on bumpy roads, the shock-absorbing spring 26 between the first sleeve 22 and the second sleeve 25 can generate elastic deformation to absorb some energy and reduce the vibration amplitude and impact. At the same time, the damper 24 can dampen the vibration, thereby improving the shock absorption effect and preventing the oxygen concentrator body 1 from shaking and being damaged, thus extending the service life of the oxygen concentrator body 1.

[0027] A rubber sleeve 5 is bonded between the first sleeve 22 and the second sleeve 25. The rubber sleeve 5 is fitted on the outside of the shock-absorbing spring 26. The rubber sleeve 5 is soft and can play a dustproof role on the outside of the damper 24 and the shock-absorbing spring 26.

[0028] Refer to the instruction manual appendix Figures 1-3 and Figure 5 The oxygen concentrator body 1 has two fixed limiting frames 3 on its outer walls. Each limiting frame 3 has a protective cover 4 inside. The outer walls of each protective cover 4 have multiple evenly distributed ventilation holes 11. The protective covers 4 can protect the ventilation openings and control panel of the oxygen concentrator body 1, preventing items inside the vehicle from colliding with the control panel of the oxygen concentrator body 1 and affecting the normal operation of the oxygen concentrator body 1. In addition, magnets 9 are fixedly embedded in the bottom walls of each limiting frame 3, and iron plates 10 are fixedly embedded in the bottom of each protective cover 4. The iron plates 10 and magnets 9 are magnetically attracted to each other. The magnetic attraction between magnets 9 and iron plates 10 makes the protective covers 4 firmly fixed in the limiting frames 3. At the same time, it is convenient for users to quickly disassemble and adjust the equipment.
