Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen generators, and particularly relates to an oxygen generator housing and an oxygen generator. Background Art

[0002] The existing oxygen generators have a relatively complex structure, with a large number of assembled components. The production and assembly processes are correspondingly complex, resulting in high production costs and low production efficiency, which have an adverse impact on the pre-production and post-inspection and maintenance of the internal oxygen generator components.

[0003] For example, the patent with the publication number CN205755119U discloses an oxygen generator housing, which focuses on the way of the sleeving mechanism between the first sub-housing and the second sub-housing, and the oxygen generator component accommodation cavity with one end open formed after the first sub-housing and the second sub-housing are connected to each other, and also includes a third sub-housing for covering the opening. The above oxygen generator housing needs three sub-housings to be combined with each other to form the overall oxygen generator housing, with a large number of assembled components, resulting in a reduction in production efficiency. The method of splicing the above first sub-housing, second sub-housing and third sub-housing will also result in poor sealing performance of the housing, because the gaps between the housings will have an adverse impact on the waterproof, dustproof and noise reduction of the oxygen generator;

[0004] In addition, a special structural member is also required inside the oxygen generator housing to fix the components to be installed inside the oxygen generator, resulting in a relatively complex structure. During the assembly process, each component needs to be installed separately, resulting in a relatively complex assembly process. Moreover, installation positions need to be reserved between the components, resulting in relatively high requirements for alignment accuracy. Otherwise, once interference occurs, the components cannot be installed in place, which will further cause the oxygen generator to malfunction, resulting in a reduction in production efficiency and safety performance.

[0057] In order to more clearly illustrate the overall concept of the present utility model, the following provides a detailed description by way of example in conjunction with the accompanying drawings of the specification.

[0058] The present utility model relates to an oxygen generator housing, such as Figures 1-11As shown in the figure, it includes a top cover 1, a chassis 2, and a base 3; the top cover 1 is provided with a first connecting part; the chassis 2 adopts an integrated structure; the chassis 2 is provided with a first positioning part and a second positioning part; the first positioning part cooperates with the first connecting part to connect the chassis 2 below the top cover 1; a wind hood 4 is connected inside the chassis 2, and a plurality of air inlet holes 7 are opened on the first side of the wind hood 4 relative to the chassis 2, and an air inlet 6 is opened on the second side of the chassis 2 opposite to the first side, and air flow enters the chassis 2 through the air inlet 6 and circumferentially flows around the wind hood 4 to the air inlet holes 7 to form an oxygen charging path; the base 3 has a second connecting part that cooperates with the second positioning part to connect the base 3 below the chassis 2.

[0059] A shell of an oxygen generator of the present application is composed of the connection of the top cover 1, the chassis 2, and the base 3, making the structure of the oxygen generator shell more simplified, the overall structure more compact, the production and assembly efficiency high, and the production cost greatly reduced. The chassis 2 adopts an integrated structure, and the chassis 2 does not need to be assembled by splicing multiple sub-shells, and there are no gaps generated by the splicing method, further improving the overall waterproof, dustproof, and noise reduction performance of the chassis 2, and then improving the safety performance of the chassis 2. By setting a first connecting part on the top cover 1 and a first positioning part on the chassis 2, and matching the first connecting part with the first positioning part, the top cover 1 is connected to the top of the chassis 2, so as to seal the top of the chassis 2 and protect the oxygen generating unit inside the chassis 2, further improving the waterproof, dustproof, and noise reduction performance of the whole machine, facilitating assembly and maintenance, and strengthening the connection strength of the oxygen generator shell; by matching the second positioning part of the chassis 2 with the second connecting part of the base 3, the base 3 is connected to the bottom of the chassis 2, so that internal structural parts such as the wind hood 4 can be first connected to the base 3 and then the chassis 2 can be directly sleeved outside the base 3. There is no splicing gap between the chassis 2 and the base 3, further enhancing the waterproof, dustproof, and noise reduction performance of the oxygen generator shell, and when assembling the oxygen generator, the oxygen generator unit can be directly installed on the base and then the chassis 2 can be put on, so as to facilitate assembly and later disassembly and maintenance.

[0060] In addition, a plurality of air inlet holes 7 are opened on the first side of the wind hood 4 connected inside the chassis 2 relative to the chassis 2, and an air inlet 6 is opened on the second side of the chassis 2 opposite to the first side, and air flow enters the chassis 2 through the air inlet 6 and circumferentially flows around the wind hood 4 to the air inlet holes 7 to form an oxygen charging path; thus, the flow path of the air flow can be extended, and some impurities will fall during the process of flowing along the oxygen charging path and will not enter the air inlet holes 7 to participate in oxygen generation and heat dissipation, so that the gas is fully filtered, and the noise of the gas flow can also be reduced, improving the noise reduction efficiency.

[0061] As a preferred embodiment, a mounting position for the filtration device 5 and a mounting position for the oxygen generator unit are further provided inside the chassis 2. A part of the airflow entering the intake hole 7 passes through the filtration device 5 and enters the oxygen generator unit for oxygen-nitrogen separation, and another part of the airflow is used to dissipate heat from the oxygen generator unit through the fan inside the wind cover 4. An atomizing joint 8 and an oxygen outlet joint 9 connected to the oxygen generator unit are connected outside the chassis 2. The atomizing joint 8 is used to output compressed air for atomization or humidification by the atomization unit, and the oxygen outlet joint 9 is used to output the oxygen of the oxygen generator unit for patients to use. An installation groove 29 is also formed outside the chassis 2 for accommodating the humidifying bottle 27. A switch 28 is further connected to the outside of the chassis 2, and the operation or shutdown of the oxygen generator is realized by pressing the switch 28.

[0062] The filtration device 5 and the oxygen generator unit are arranged inside the chassis 2. The airflow entering the intake hole 7 is divided into two paths. One path passes through the filtration device 5 and enters the oxygen generator unit to realize oxygen-nitrogen separation and oxygen preparation, and the other path uses the airflow through the fan to dissipate heat from the oxygen generator unit. Through the structural layout of the present application, a reasonable distribution of the airflow is realized, which can not only realize the heat dissipation and cooling treatment of the oxygen generator unit but also realize the sufficient preparation of oxygen, improve the heat dissipation performance and oxygen production efficiency, and further improve the service life of the oxygen generator housing and even the oxygen generator.

[0063] As a preferred embodiment, an exhaust hole 30 facing the top cover 1 is provided on the side of the wind cover 4 opposite to the intake hole 7, and an air inlet hole 31 is formed on the side of the filtration device 5 facing the exhaust hole 30. The airflow in the intake hole 7 of the wind cover 4 is discharged through the exhaust hole 30 and then enters the filtration device 5 through the air inlet hole 31.

[0064] As Figures 9-11 shown, the gas inside the wind cover 4 is output through the exhaust hole 30. One path is output through the exhaust hole 30, enters the filtration device 5 through the air inlet hole 31, and then enters the oxygen generator unit through the filtration device 5 to realize oxygen-nitrogen separation.

[0065] As a preferred embodiment, the oxygen generator housing further includes a bottom plate 32. The bottom plate 32 is connected to the bottom plate 32 mounting position of the chassis 2. The bottom plate 32 can separate the chassis 2 from the base 3, forming a first cavity for mounting the wind cover 4 inside the chassis 2, so that an exhaust passage for gas flow is formed inside the base 3. Vent holes for connecting the first cavity and the exhaust passage are provided on the bottom plate 32. An exhaust port 1 for gas discharge is provided on the periphery of the base 3. The gas in the first cavity enters the exhaust passage through the vent holes and then flows out from the exhaust port 10.

[0066] By providing a bottom plate 32 between the chassis 2 and the base 3, the installation of the oxygen generator unit located above the base 3 in the chassis 2 can be achieved, enabling the oxygen generator unit to be stably connected inside the chassis 2, thereby enhancing the connection strength of the oxygen generator and avoiding misalignment during transportation or use due to shaking. An exhaust passage for gas circulation is formed inside the base 3. Vent holes communicating with the exhaust passage are provided on the bottom plate 32. The base 3 also has an exhaust port 10, allowing the airflow for heat dissipation entering the interior of the chassis 2 and gases such as nitrogen generated during the oxygen generation process to flow out to the outside through the vent holes, the exhaust passage, and the exhaust port 10, preventing the airflow from staying inside the oxygen generator housing, further improving the noise reduction performance of the oxygen generator, and enhancing the operating efficiency of the oxygen generator.

[0067] Further, on the side of the bottom plate 32 facing the chassis 2, a plurality of positioning grooves for accommodating elastic components connected to the oxygen generator unit are provided; the elastic components include springs connected in the positioning grooves and elastic pads connected to the springs, and the elastic pads can be connected to the oxygen generator unit.

[0068] There are a plurality of positioning grooves for accommodating elastic components on the bottom plate 32. The elastic components are used to buffer the impact force between the bottom plate 32 and the oxygen generator unit. The springs are connected in the positioning grooves, and the springs are connected with elastic pads. The elastic pads are connected to the oxygen generator unit, thereby avoiding rigid connection between the oxygen generator unit and the bottom plate 32. During transportation or use, shaking may cause friction or even wear between the oxygen generator unit and the bottom plate 32. The collision force between the oxygen generator unit and the bottom plate 32 can be buffered, further enhancing the elasticity of the connection between the oxygen generator unit and the bottom plate 32, reducing the impact force between the oxygen generator unit and the bottom plate 32. The impact force is absorbed and dispersed through the self-elastic deformation of the elastic pads and springs, further protecting the oxygen generator unit and the bottom plate 32, avoiding damage to the entire oxygen generator, and increasing the service life of the oxygen generator.

[0069] Regarding the connection method between the top cover 1 and the chassis 2, it is not limited by this application. Specifically, any of the following implementation methods can be adopted:

[0071] As Figure 3 shown, a first convex edge 14 protruding from the surface of the top cover 1 is provided on the inner circumference of the top cover 1. The first convex edge 14 surrounds at least part of the circumference of the top cover 1. Preferably, the first convex edge 14 covers the entire circumference of the top cover 1 to enhance the connection firmness.

During use, the top cover 1 is placed on the top of the chassis 2, and the first convex edge 14 is fitted into the first groove 15 to achieve snap connection of the top cover 1 to the chassis 2. By providing the first convex edge 14 on the inner side of the top cover 1 and the second groove 17 on the top of the chassis 2, the top cover 1 can be fitted into the chassis 2, and there is no splicing gap between the top cover 1 and the chassis 2 along the height direction of the chassis 2. This not only enhances the waterproof, dustproof and noise reduction performance, strengthens the connection stability between the top cover 1 and the chassis 2, but also improves the connection aesthetics between the top cover 1 and the chassis 2, enhancing the user experience.

[0072] Embodiment 2: The first connecting portion includes a first groove 15 provided at the outer edge where the top cover 1 and the chassis 2 are joined, and the first positioning portion includes a first convex edge 14 provided at the outer edge of the chassis 2 corresponding to the first groove 15.

[0073] In this embodiment, different from the above embodiment, the first convex edge 14 is provided protruding from the top of the chassis 2, at least in a partial area around the circumference of the chassis 2. Preferably, the first convex edge 14 surrounds the entire circumference of the top of the chassis 2 to enhance the connection strength between the chassis 2 and the top cover 1. A first groove 15 is provided on the inner side of the top cover 1 corresponding to the first convex edge 14.

[0082] Based on the above two implementation manners, the connection between the chassis 2 and the base 3 is realized by the cooperation and connection of the first convex edge and the first groove. In order to further enhance the connection strength between the chassis 2 and the base 3 and the accuracy of assembling the chassis 2 and the base 3, and to avoid the dislocation phenomenon of the oxygen generator housing after assembly due to shaking during transportation and use, there are also the following two implementation manners:

[0083] Embodiment Three: The second positioning portion includes a second convex edge 16 provided on the outer edge where the chassis 2 and the base 3 are joined, and the second connection portion includes a second groove 17 provided on the outer edge of the base 3 corresponding to the second convex edge 16; the second positioning portion further includes a third boss 20 provided inside the chassis 2, and the third boss 20 has a third screw hole 24; the second connection portion further includes a fourth boss 21 provided inside the base 3, and the fourth boss 21 has a fourth screw hole 25 that mates with the third screw hole 24.

[0084] Embodiment Four: The second positioning portion includes a second groove 17 provided on the outer edge where the chassis 2 and the base 3 are joined, and the second connection portion includes a second convex edge 16 provided on the outer edge of the base 3 corresponding to the second groove 17; the second positioning portion further includes a third boss 20 provided inside the chassis 2, and the third boss 20 has a third screw hole 24; the second connection portion further includes a fourth boss 21 provided inside the base 3, and the fourth boss 21 has a fourth screw hole 25 that mates with the third screw hole 24. The chassis 2 and the base 3 are connected by screwing through the third screw hole 24 and the fourth screw hole 25.

[0085] As Figure 5 and Figure 6 shown, a second groove 17 that surrounds at least a partial area of the circumference of the chassis 2 is connected near the bottom inside the chassis 2. Preferably, the second groove 17 surrounds the entire circumference of the chassis 2. With such a setting, a preset distance is formed from the second groove 17 of the chassis 2 to the bottom of the chassis 2 to form a socketing area where the base 3 can be socketed inside the chassis 2. During use, the chassis 2 is placed above the base 3 so that the bottom of the chassis 2 can be socketed outside the base 3, and the socketing area on the chassis 2 can cover the outer peripheral surface of the base 3.

This can not only enhance the connection strength of the oxygen generator housing, achieve the performance of waterproofing, dustproofing and noise reduction, but also enhance the aesthetic appearance and improve the user experience.

[0086] Above the second groove 17 of the chassis 2, there is a third boss 20, which is arranged opposite to the fourth boss 21 protruding from the inner wall and connected inside the base 3, so that the third screw hole 24 and the fourth screw hole 25 can cooperate; the chassis 2 and the base 3 are firmly connected by screws passing through the third screw hole 24 and the fourth screw hole 25, so that the connection between the chassis 2 and the base 3 is more firm, and the support strength of the oxygen generator unit can be enhanced.

[0087] It should be noted that, in addition to the above embodiments, the base 3 and the chassis 2 can also be fixedly connected by means including but not limited to socket structures, snap structures, screws or cementing.

[0088] As a preferred embodiment, the top cover 1 includes a cover body 11, a handle 12 connected above the cover body 11 and a panel 13; the cover body 11 is provided with a first connecting portion, and the panel 13 has a display screen for displaying the working state of the oxygen generator unit.

[0090] This application also relates to an oxygen generator, an oxygen generator based on an oxygen generator housing according to any one of the above, including an oxygen generator housing, a filtering device 5 connected inside the oxygen generator housing, and an oxygen generator unit. The oxygen generator unit includes a compressor, an adsorption tower and a gas storage tank respectively connected inside the chassis 2.

[0091] The chassis 2 is an integral structure, effectively isolating water, dust and noise, improving the level of protection of the oxygen generator housing against the entry of solid foreign objects, and greatly improving the degree of tightness against moisture and water intrusion. Due to the good sealing performance of the oxygen generator housing, the internal air flow of the oxygen generator housing, the structures such as the compressor, adsorption tower and gas storage tank in the oxygen generator unit, and the noise sources such as the fan installed in the wind cover 4 are effectively isolated, further improving the noise reduction performance of the oxygen generator. As Figure 5 shown, when the oxygen generator is in use, external air enters the chassis 2 through the air inlet 6 of the chassis 2, and the air entering the chassis 2 bypasses the periphery of the wind cover 4 and reaches the air inlet holes 7 on the side wall of the wind cover 4, and enters the wind cover 4 from the air inlet holes 7. The gas entering the wind cover 4 is divided into two paths: the first path of air is discharged through the exhaust holes 30 of the wind cover 4 and then enters the air filtering device 5 through the air inlet holes 31 of the filtering device 5 for filtration, and then enters the compressor assembly and the molecular sieve system for oxygen-nitrogen separation; the second path of air, due to the action of the fan, is directly blown on the compressor by the fan and then discharged from the ventilation holes of the bottom plate 32 and the exhaust port 10 of the base 3, so as to meet both the oxygen generation requirements of the oxygen generator unit and the heat dissipation requirements of the compressor assembly; the heat dissipation effect and oxygen generation effect during the entire intake process are further improved, and the service life of the oxygen generator is further extended.
