Detailed implementation manners

[0023] To make the above objects, features and advantages of this utility model more obvious and understandable, the following detailed description of the specific implementation manners of this utility model will be given in conjunction with the accompanying drawings of the specification.

[0024] In the following description, many specific details are set forth to fully understand this utility model. However, this utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of this utility model. Therefore, this utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of this utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0026] Furthermore, this utility model is described in detail in conjunction with schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of this utility model here. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0027] Refer to Figures 1-5, an embodiment of the present utility model provides a small oxygen generator with a noise reduction structure, including a compressor unit and a molecular sieve for realizing the oxygen generation function. After the air enters the compressor unit from the air inlet end and is compressed, nitrogen and oxygen are separated under the action of the molecular sieve, and nitrogen and other mixed gases are discharged through the nitrogen discharge end. The following will summarize this part of the combination as the oxygen generation assembly. In addition, the present utility model further includes an encapsulation part 1 and a component 2. The encapsulation part 1 is used to encapsulate the whole machine. Specifically:

[0028] The component 2 is arranged inside the encapsulation part 1. The oxygen generation assembly is arranged on the component 2 and there is no contact with the encapsulation part 1;

[0029] The component 2 has a flexible structure, and an independent and distributed intake branch 3 and exhaust branch 4 are respectively constructed thereon. All the intake branches 3 are configured to communicate with the air inlet end of the oxygen generation assembly, and all the exhaust branches 4 are configured to communicate with the nitrogen discharge end of the oxygen generation assembly;

[0030] Based on the above, when the oxygen generation assembly is working, the external air is dispersed and enters through multiple intake branches 3. Similarly, nitrogen and other mixed gases are dispersed and discharged through multiple exhaust branches, so as to avoid the occurrence of highly concentrated gas flow, achieve the sound absorption effect, and through the flexible characteristics of the component 2, the formation of its own vibration of the component 2 can be further avoided, thereby further eliminating the sound effect caused by intake and exhaust;

[0031] Synchronously with the above, when the oxygen generation assembly is working, by virtue of the flexible characteristics of the component 2, the transmission of vibration to the encapsulation part 1 can be reduced, thereby reducing the occurrence of the phenomenon that the noise emitted from the oxygen generation assembly is transmitted to the external air;

[0032] Compared with the prior art, the present utility model can achieve a better noise reduction effect as a whole by performing sound absorption treatment on the intake process, exhaust process and the operation of the oxygen generation assembly respectively. For the component 2 in the present utility model, structures such as sponge blocks or silicone blocks can be used.

[0033] Further, referring to Figures 2-5 , the component 2 has a first side 5 and a second side 6. The intake branch 3 penetrates through the first side 5 and the second side 6. The first side 5 is provided with a first cover 7, which forms a covering effect on the first side 5. The air inlet end is connected to the inside of the first cover 7. When intake, the external air passes through the component 2 from the second side 6 and then reaches the inside of the first cover 7 to enter the air inlet end, realizing the effect of the air passing through the component 2, thereby increasing the sound absorption effect of the component 2 on the air.

[0034] Further, referring to Figures 2-5, the component 2 has a third side 8 and a fourth side 9, and the exhaust branch 4 penetrates through the third side 8 and the fourth side 9. The second housing 10 is provided on the third side 8 in the same way as the first housing 7. The nitrogen discharge end is communicated with the inner side of the second housing 10. When exhausting, nitrogen enters the second housing 10 and then reaches the fourth side 9 through the plurality of exhaust branches 4 respectively, so as to realize the discharge of nitrogen along the inside of the whole component 2, thereby increasing the silencing effect during exhaust.

[0035] Further, referring to Figures 4-6 , a back side is formed between the first side 5 and the second side 6. Similarly, a back side is also formed between the third side 8 and the fourth side 9, so that the lengths of the intake branch 3 and the exhaust branch 4 can be increased, and the intake branch 3 and the exhaust branch 4 are arranged perpendicular to each other, so that the utilization effect of the volume of the component 2 can be fully improved on the basis of non-interference.

[0036] Further, referring to the setting manner of the component 2 on the encapsulation part 1 in the figure. Specifically, the present invention further includes a supporting part 11. The supporting part 11 is of a frame structure and only plays a supporting role. The supporting part 11 is connected to the encapsulation part 1 through a buffer mechanism 12. The component 2 is arranged on the supporting part 11, so as to achieve an indirect connection effect with the encapsulation part 1. By means of the buffer mechanism 12, the phenomenon that the vibration on the component 2 is transmitted to the encapsulation part 1 can be further reduced, so as to further prevent the vibration of the oxygen generation assembly from being transmitted to the encapsulation part 1, thereby reducing the sound emitted by the oxygen generation assembly.

[0037] Further, referring to Figures 1-3 , the encapsulation part 1 further includes a base 101 and a housing 102, and the two are detachably connected. For example, they can be assembled by a bolt assembly. The buffer mechanism 12 is connected to the base 101. When maintaining the internal oxygen generation assembly part, only the housing 102 needs to be removed, thereby improving the overall practicability of the present invention. For the buffer mechanism 12, a spring assembly or the like can be adopted.

[0038] Further, referring to Figures 2-5, for the setting of the component 2 on the supporting part 11, specifically, the second side 6 forms a lap joint with the supporting part 11 to maintain contact, so that when admitting air, the air flows from the bottom upwards to the second side 6. The peripheral side of the housing 102 is provided with grille openings 13, and the grille openings 13 are distributed on two opposite sides of the housing 102, and their height is slightly lower than the second side 6. Thus, when admitting air, the outside air can enter the housing 102 through the grille openings 13 and directly reach the second side 6 upwards, so as to reduce the path that the air flow passes through from outside the device to the second side 6, thereby improving the air intake efficiency. The fourth side 9 is extended to be located outside the housing 102, and this side is not on the same side as the position where the grille openings 13 are formed, so as to separate the air intake place from the final exhaust place, thereby maintaining a sufficient distance.

[0039] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without excessive experimentation, such development efforts will be a routine task of design, manufacturing and production.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
