[0008] The length and width of the card slot are equal to those of the assembly slot, and the opening depth of the card slot is equal to the protruding height of the limit block. When the vertical surface of the push-pull plate is embedded in the inspection opening, the limit block protrudes from the assembly slot through the spring and is embedded in the card slot.

[0009] A clearance groove is opened inwardly on the outer surface of the push-pull plate, the opening height of the clearance groove is equal to the depth of the card slot, and the length of the clearance groove is less than the length of the assembly slot and is connected to the assembly slot.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The oxygen production device of the present application prepares oxygen based on the air separation technology in the prior art. Therefore, the device will miniaturize the various components used for air separation and install them centrally to meet the production of oxygen. Due to the miniaturization of the components, considering that the later assembly and maintenance in the box are inconvenient, the device divides the box into two parts, the upper and lower parts, and a sliding push-pull plate is designed in the lower cavity.

In order to prevent the connecting pipe from being exposed to the outside and being contaminated by the external environment when not in use, the present application provides an operating window on the box body to provide an operating space when the connecting pipe is connected to the external pipeline. At the same time, a baffle is rotatably connected outside the operating window. When not in use, the baffle is used to shield the operating window to protect the connecting pipe and prevent the connecting pipe from being directly exposed to the outside and being contaminated.

[0017] (3) Furthermore, the molecular sieve used for oxygen separation in the present application is installed in a separation box. In order to achieve a better effect of screening oxygen, the present application sets up multiple separation boxes, each of which is connected to the filter by a branch pipe, and a valve is set on the branch pipe. The valve can be used to control the oxygen path entering each separation box from the filter box and the volume of air entering the separation box, thereby controlling the speed and efficiency of oxygen preparation to a certain extent. At the same time, compared with the production of oxygen in a single separation box, the design of multiple separation boxes makes the burden of each separation box smaller, so that the internal molecular sieve can be used for a longer time.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0031] See also Figure 1 , Figure 2 and Figure 7The portable oxygen generator in this embodiment includes a box 100, and a handle 100a is rotatably connected to the box 100 for easy carrying of the oxygen generator. The box 100 is a hollow structure, and a partition is fixedly installed horizontally in the center of the box 100. The partition increases the three-dimensional structure inside the box 100 to divide the box 100 into two upper and lower cavities. The oxygen production principle in this embodiment adopts the air separation technology in the prior art. The core components of the air separation technology are a compressor 101, a filter 102, a separation box 103 and an air storage tank 104. After the compressor 101 compresses and pressurizes the external air, the compressed air is sent to the filter 102 by using an air guide pipe 101a connected to the output end of the compressor 101 to remove impurities and water in the air. The impurity-free air enters the separation box 103 through the air delivery pipe 102a connected to the output end of the filter 102. The separation box 103 has a built-in molecular sieve. The molecular sieve adsorbs nitrogen, while oxygen passes through the molecular sieve layer and is discharged. When the molecular sieve is saturated, a regeneration cycle is triggered. At this time, the molecular sieve is heated to release the adsorbed nitrogen, and then adsorbs it again. The generated oxygen is delivered to the gas storage tank 104 for storage using the air delivery pipe 103a set at the output end of the separation box 103. The gas storage tank 104 is connected to a connecting pipe 104a, which can be connected to an external pipeline for easy use. Therefore, in this embodiment, the compressor 101 and the filter 102 are installed in the lower cavity, and the separation box 103 and the gas storage tank 104 are installed in the upper cavity to form an oxygen production mechanism together.

[0032] See also Figure 4 and Figure 51 is a schematic diagram of the structure for facilitating the installation of oxygen production components in this embodiment. Since the portable oxygen production device is small in size, each oxygen production component is assembled after being reduced in size in proportion. The different functions of the oxygen production components will lead to different failure rates and maintenance requirements. The internal space of the portable oxygen production device is limited. Therefore, it is inconvenient to operate inside the device when inspecting the oxygen production components that need maintenance. Therefore, in this embodiment, inspection ports 100d are opened on opposite sides of the lower cavity of the box body 100. The inspection ports 100d are connected to the lower cavity. Push-pull plates 200 are symmetrically slidably connected in the lower cavity. The compressor 101 and the filter 102 that need regular maintenance among the oxygen production components are placed on the two push-pull plates 200 respectively, so that the compressor 101 and the filter 102 can be pulled out of the box body 100 by pulling the push-pull plates 200 for easy maintenance. Further, in order to hide the inspection port 100d, the present application makes the push-pull plate 200 an L-shaped structure, so that the push-pull plate 200 It is divided into a horizontal surface and a right-angle surface, and the right-angle surface is used to fill the inspection opening 100d, so as to effectively protect the inside of the box body 100 and make the device more beautiful. It is worth noting that the push-pull plate 200 and the inspection opening 100d are only fitted to cover, but cannot be fixed. It is easy to be shaken during carrying, causing the push-pull plate 200 to accidentally slide out. Therefore, in this embodiment, an assembly groove 200b is opened on the right-angled upper surface of the push-pull plate 200, and the assembly groove 200b is symmetrically installed with Spring 202, the upper surface of spring 202 is connected to limit block 201, limit block 201 protrudes from assembly groove 200b, and a slot is provided on the inner wall of inspection port 100d opposite to limit block 201, and the limit block 201 is connected with the slot to fix the right-angle surface of push-pull plate 200 in inspection port 100d. Furthermore, considering that compressor 101 and filter 102 can be pulled out from box body 100, air duct 101a and air delivery pipe 102a need to be pre-placed with sufficient length.

[0033] See also Figure 8200b, and the depth of the slot is equal to the height of the protruding stopper 201. When the vertical surface of the push-pull plate 200 is embedded in the inspection port 100d, the stopper 201 protrudes from the assembly slot 200b through the spring 202 and is embedded in the slot. Furthermore, in order to facilitate the operation of the stopper 201, after the stopper 201 is disconnected from the slot, the locking structure is in an open state, so that the push-pull plate 200 can slide and be pulled out. The opening height of the giving way groove 200c is equal to the depth of the card slot, and the length of the giving way groove 200c is less than the length of the assembly groove 200b and is connected to the assembly groove 200b. The limit block 201 is exposed to the outside through the giving way groove 200c, and a handle is connected to the outer surface of the limit block 201, and the handle extends to the outside through the giving way groove 200c. The handle is used to press downward to make the limit block 201 squeeze the spring 202. The space generated by the spring 202 being compressed is for the limit block 201 to descend. After the limit block 201 descends, it is detached from the card slot, and then an outward force is applied to the push-pull plate 200 through the handle, so that the push-pull plate 200 is pulled out of the box body 100.

[0034] See also Figure 7 In order to facilitate the compressor 101 to draw air from the outside, the present application provides an air inlet hole on the vertical surface of the push-pull plate 200, and the input end of the compressor 101 is in contact with the air inlet hole to facilitate air absorption.

[0035] See also Figure 2 and Figure 6 This is the air supply control structure diagram in this embodiment. First, in order to increase the efficiency of air separation, the present application sets up multiple separation boxes 103, and the air separated by the multiple separation boxes 103 is provided by the filter 102. Therefore, in order to make the air intake of each separation box 103 equal, the present application uses a tee to connect multiple branch pipes at the end of the air supply pipe 102a, and each branch pipe is equipped with a valve and is connected to the multiple separation boxes 103 one by one. The valve can be used to control the oxygen path of the filter 102 entering each separation box 103 and the volume of air entering the separation box 103, so that the speed and efficiency of oxygen preparation can be controlled to a certain extent. At the same time, compared with the production of oxygen by a single separation box 103, the design of multiple separation boxes 103 makes the burden of each separation box 103 smaller, so that the internal molecular sieve can be used for a longer time. In order to facilitate the operation of the valve, the branch pipes are all arranged outside the box body 100 in the present application so that the valves on the branch pipes are located outside the box body 100.

[0036] See also Figure 3This is a structural diagram of the protection mechanism in this embodiment. This embodiment is provided with an operation window 100c. The operation window 100c provides an operation space when the connecting pipe 104a is connected to an external pipe. In order to prevent the connecting pipe 104a from being exposed to the outside and contaminated by the external environment when not in use, this embodiment is covered with a baffle 100b on the outside of the operation window 100c. Connecting ears 100b-1 are connected on both sides of the baffle 100b. The connecting ears 100b-1 are rotatably connected to both sides of the inclined surface. In order to facilitate the unobstructed rotation of the baffle 100b, an inclined surface is cut on one side of the upper cavity of the box body 100 close to the gas tank 104, and the operation window 100c is arranged below the surface of the box body 100.

[0037] See also Figure 4 In order to constrain the sliding push-pull plate 200, the present application symmetrically opens a slide groove on the bottom surface of the lower cavity of the box body 100, and a cross bar is centrally provided on the upper surface of the slide groove. The lower surface of the push-pull plate 200 is symmetrically provided with a slide bar 200a, and the slide bar 200a is slidably connected in the slide groove.

[0038] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
