Description

Technical Field

[0001] The utility model relates to an air outlet structure of an oxygen generator, belonging to the technical field of oxygen generators. Background Art

[0002] Household oxygen generators have increasingly entered families in need. Common household oxygen generators adopt the pressure swing adsorption technology and need to use a compressor to pressurize air to maximize the oxygen generation efficiency of the oxygen generator. The compressor is also the main component of the atomizer. Therefore, an oxygen generator adopting the pressure swing adsorption technology usually integrates an atomization function. Such an oxygen generator has both an oxygen outlet (oxygen interface) and an atomization outlet (atomization interface). The oxygen outlet of the existing oxygen generator is mostly exposed. The advantage of this solution is that the oxygen generator can be directly used when it is turned on, and it is convenient to insert and remove the nasal oxygen tube. However, the oxygen outlet is directly exposed to the air, and lack of protection measures makes it extremely easy to be contaminated by dust, bacteria or other foreign objects in the environment. Since the atomization port of the oxygen generator is communicated with the air outlet of the compressor, there will be a large back pressure (air pressure) at the atomization port during normal oxygen generation work. Commonly, metal parts with good strength are used for sealing in a threaded manner, and the unsealing operation during atomization is relatively complicated. Due to the development of oxygen generation technology, the power of the compressor used in current household small oxygen generators is relatively small, and the generated back pressure is below 140 kPa, and ordinary silicone plugs can be used for sealing. However, how to reliably set the air outlet cover of the oxygen generator is still a technical problem to be solved in the field. In addition, how to simplify the assembly process of the air outlet structure of the oxygen generator is also a technical problem to be solved in the field. Summary of the Utility Model

[0003] In order to overcome the problems existing in the prior art, the utility model provides an air outlet structure of an oxygen generator, which is beneficial to simplifying the installation process of the air outlet structure. The specific technical solutions are as follows.

[0004] An air outlet structure of an oxygen generator, characterized by comprising: a housing, a cylinder member arranged on the housing, an air outlet pipe bracket and an air outlet cover;

[0005] The cylinder member extends inward from the inner surface of the housing, and both the inner end and the outer end of the cylinder member are open;

[0006] The air outlet pipe bracket includes a plate member, an air inlet joint and an air outlet joint. The air inlet joint and the air outlet joint are respectively located on both sides of the plate member and are communicated with each other; the plate member is fixed to the housing and / or the cylinder member, and the plate member covers and abuts against the inner end of the cylinder member, and the air outlet joint is accommodated in the cylinder member;

[0007] The air outlet cover is covered on the outer end of the cylinder member.

[0008] With the above technical solution, during assembly, the air outlet pipe bracket is fixed to the housing and / or the cylinder component through fasteners. The air inlet joint is connected to the air pipe inside the oxygen generator. The air outlet cover covers the outer end of the cylinder component, thereby protecting the air outlet joint inside the cylinder component and preventing foreign objects from entering the air outlet joint. When the oxygen or atomization function of the oxygen generator is needed, uncover the air outlet cover and connect an external pipe to the air outlet joint. The solution of the present utility model greatly simplifies the installation process of the air outlet structure.

[0009] Further, the air outlet cover has an inner plug and an outer plug. When the air outlet cover is covered on the outer end of the cylinder component, the inner plug is in tight fit with the inner wall of the air outlet joint, and the outer plug is in tight fit with the outer wall of the air outlet joint. Tight fit means close fit, with a large frictional force between the two and a certain degree of airtightness, preventing air leakage from the air outlet joint and avoiding the air pressure inside the air outlet joint from pushing the air outlet cover away from the air outlet joint.

[0010] Further, the periphery of the housing corresponding to the outer end of the cylinder component has a groove for accommodating the air outlet cover. By providing the groove, it can be avoided that the air outlet cover protrudes from the outer surface of the housing after installation, making the air outlet cover roughly flush with the outer surface of the housing.

[0011] Further, the inner side of the air outlet cover has a boss that is engaged with the inner wall of the outer end of the cylinder component. The cooperation between the boss and the cylinder component achieves a certain sealing effect, preventing foreign objects from entering the cylinder component and the air outlet joint; moreover, the boss can improve the overall strength of the air outlet cover and prevent large deformation.

[0012] Further, a hook hole is provided on the housing, and an anti - detachment hook is provided on the air outlet cover, and the anti - detachment hook is inserted into the hook hole. By providing the anti - detachment hook, when uncovering the air outlet cover, it can be prevented that the air outlet cover detaches from the housing and is easily lost.

[0013] Further, the air outlet cover is made of an elastic material. Preferably, the air outlet cover is made of TPU or silica gel.

[0014] Further, an installation groove is provided on the inner end surface of the cylinder component, and a sealing ring is provided in the installation groove. The plate component abuts against the inner end of the cylinder component through the sealing ring. The sealing ring helps to prevent foreign objects such as moisture from entering the inside of the oxygen generator.

[0015] Further, the plate component is also provided with positioning rib strips that are attached to the outer wall of the cylinder component. By providing the positioning rib strips, when installing the air outlet pipe bracket, the air outlet pipe bracket can be quickly and accurately positioned.

[0016] Further, the air outlet cover is an oxygen port cover, and the corresponding air outlet joint is an oxygen outlet joint.

[0017] Further, the air outlet cover is an atomizing port cover, and the corresponding air outlet joint is an atomizing outlet joint.

[0018] Based on the same inventive concept, the present utility model also relates to an oxygen generator having the above-mentioned air outlet structure of the oxygen generator.

[0019] The present utility model greatly simplifies the installation process of the air outlet structure, is simple to use and convenient to operate, can effectively protect the air outlet of the oxygen generator, and prevent the internal pipelines such as the oxygen outlet and atomizing outlet of the oxygen generator from being contaminated by external impurities and bacteria.

Among them, the plate member 3.1 is fixed to the housing 1 by fasteners. Of course, the plate member 3.1 can also be fixed to the cylinder member 2.

[0032] Preferably, the housing 1 has a groove 1.1 around the outer end corresponding to the cylinder member 2, and the groove 1.1 is used to receive the air outlet cover 4. By providing the groove 1.1, it is possible to prevent the air outlet cover 4 from protruding from the outer surface of the housing 1 after installation, so that the air outlet cover 4 is substantially flush with the outer surface of the housing 1.

[0033] In a specific embodiment, as Figure 6 shown, the air outlet cover 4 is an atomizing port cover, which has an inner plug 4.1 and an outer plug 4.2.
