Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen diffusion technology, specifically to an oxygen diffusion terminal. Background Technology
[0002] In high-altitude areas where oxygen is generally scarce, oxygen generators are widely used. The principle behind these generators is as follows: Molecular sieves are installed inside the generator. When air is compressed by a compressor and enters the molecular sieve tower, the sieves adsorb nitrogen from the air, while the unabsorbed oxygen is collected. Because the generator absorbs outside air and separates oxygen, the separated oxygen inevitably contains some impurities, dust, etc. Sometimes, impurities are also unavoidable in the oxygen delivery pipeline, resulting in insufficiently clean oxygen at the oxygen diffusion terminal outlet. Therefore, a filtration device is needed to filter the oxygen from the oxygen supply system.
[0003] For example, in the prior art, Chinese utility model patent with publication number CN213698400U discloses a diffusion oxygen distribution device, including an oxygen inlet, an oxygen outlet, and an oxygen pipe. The oxygen inlet is located outside the room and connected to an oxygen supply device. The oxygen pipe connects the oxygen inlet and the oxygen outlet. The oxygen outlet is located inside the room and includes a cylinder support and an oxygen outlet cylinder. The upper part of the cylinder support is mounted on the upper part of the room, and the lower part is connected to the oxygen outlet cylinder. The front and rear parts of the oxygen outlet cylinder are respectively equipped with a front cover and a rear cover. The front cover has several ventilation holes, and oxygen diffuses from the ventilation holes to the surrounding area. The rear cover is equipped with a wall-penetrating connector, and the other end of the wall-penetrating connector is connected to the oxygen pipe.
[0004] However, the oxygen diffusion device mainly focuses on reducing oxygen output noise. Furthermore, although the patent also includes a filter, it is located at the oxygen inlet, neglecting the impurities that may exist in the oxygen delivery pipeline of the oxygen supply system. In view of this, this application proposes a device that designs the filter structure at the oxygen diffusion terminal. Utility Model Content
[0005] This invention aims to solve the problem that the oxygen at the outlet of the diffusion terminal is not clean enough due to impurities in the oxygen itself or in the delivery pipeline. It proposes an oxygen diffusion terminal with a filter structure. The filter structure can be quickly disassembled and assembled through a detachable design, which ultimately improves the cleanliness of the oxygen at the outlet of the diffusion terminal.
[0006] To achieve the above-mentioned objectives, the technical solution of this utility model is as follows: An oxygen diffusion terminal includes an oxygen outlet cylinder, one end of which is connected to an oxygen supply device, and the other end is an oxygen outlet. A base is provided at the end of the oxygen outlet cylinder near the oxygen outlet. A diffusion assembly covering the oxygen outlet is detachably connected to the base. The diffusion assembly includes a shell, an inner filter element, and an outer diffusion plate. The inner filter element is installed inside the shell and faces the oxygen outlet. The outer diffusion plate is located at the center of the end face of the shell away from the base and covers the inner filter element. The outer diffusion plate has uniform diffusion mesh holes.
[0007] Furthermore, a circular groove is provided around the oxygen outlet on the end face of the base, and a connecting end that matches and connects to the circular groove is provided on the side of the outer shell near the base, and the connecting end is inserted into the circular groove.
[0008] Furthermore, multiple slots are evenly arranged around the circular groove on the end face of the base, and several buckles are provided on the side wall of the connecting end of the outer shell, which are connected to the slots one by one.
[0009] Furthermore, both the slot and the buckle are made of magnets.
[0010] Furthermore, the outer shell is provided with a number of pins, and the edge of the inner filter element is provided with connecting ears that match the number of pins. The connecting ears are provided with pin holes that cooperate with the pins.
[0011] Furthermore, a differential pressure sensor is fixedly installed at the center of the outer diffusion plate.
[0012] Furthermore, a mounting bracket for mounting a diffusion fan is provided on the end face of the outer casing near the outer diffusion plate.
[0013] Furthermore, an isolation net is also installed at the oxygen outlet.
[0014] The working principle of this utility model is as follows: Installation stage: Place the inner filter element inside the outer shell, and then insert the entire diffusion assembly into the circular groove on the base through the connecting end. Rotate the outer shell according to the position of the slot opening on the base so that the buckle on the outer shell is screwed into the slot. The slot and buckle are positioned by magnetic adsorption. Working phase: After the oxygen supply equipment is turned on, oxygen enters the oxygen outlet cylinder, and then enters the inner filter element from the oxygen outlet to filter out fine impurities and dust in the gas. After that, oxygen enters the room through the diffusion mesh on the outer diffusion plate to distribute oxygen. Replacement phase: After the diffusion terminal has been used for a period of time, remove the diffusion components, replace the inner filter element and clean the diffusion mesh on the outer diffusion plate, and then reinstall it in the same way. The diffusion terminal can then continue to operate.
[0015] In summary, this utility model has the following advantages: 1. This utility model proposes an oxygen diffusion terminal with a filter structure, which improves the cleanliness of the oxygen at the outlet of the diffusion terminal, and the filter element can be quickly disassembled and installed through the detachable design, making maintenance very convenient.
[0016] 2. In this utility model, the quick matching and connection of the diffusion components can be achieved by the cooperation between the circular groove on the base and the connecting end of the outer shell; the quick positioning of the diffusion components can be facilitated by the cooperation of the slot and the buckle. The slot and the buckle are designed as a magnetic structure, which can improve the connection stability of the diffusion components.
[0017] 3. In this utility model, the differential pressure sensor can be used to detect the air pressure and indicate whether the inner filter element needs to be replaced.
[0018] 4. In this utility model, the inner filter element and the outer shell are quickly connected by a pin and a connecting ear, enabling quick disassembly and replacement.
[0019] 5. In this utility model, a mounting bracket for a diffusion fan is provided on the outer side of the outer diffusion plate. A diffusion fan can be added to diffuse the oxygen at the outlet of the outer diffusion plate, thereby improving the oxygen diffusion effect at the oxygen outlet.
[0020] 6. In this utility model, the isolation net can isolate large impurity particles or foreign objects from the oxygen inlet pipe. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] Example 1: An oxygen diffusion terminal, such as Figure 1As shown, it includes an oxygen outlet cylinder 13, one end of which is connected to an oxygen supply device, and the other end is an oxygen outlet. A base 1 is provided near the oxygen outlet of the oxygen outlet cylinder 13. A diffusion assembly 4 covering the oxygen outlet is detachably connected to the base 1. The diffusion assembly 4 includes a shell 401, an inner filter element 402, and an outer diffusion plate 403. The inner filter element 402 is installed inside the shell 401 and faces the oxygen outlet. The outer diffusion plate 403 is located at the center of the end face of the shell 401 away from the base 1 and covers the inner filter element 402. The outer diffusion plate 403 is provided with uniform diffusion mesh.
[0029] In this invention, the inner filter element 402 serves to intercept large impurity particles or foreign objects in the air intake pipe. After the dispersion terminal has been used for a period of time, the dispersion assembly 4 is removed, the inner filter element 402 is replaced, the mesh of the outer dispersion plate 403 is cleaned, and then it is reinstalled. Disassembly and maintenance are convenient.
[0030] Example 2: Based on Example 1, the detachable connection structure between the diffusion component 4 and the base 1 will be further described.
[0031] like Figure 2 As shown, a circular groove 5 is provided around the oxygen outlet on the end face of the base 1. The outer shell 401 is provided with a connecting end 6 that matches and connects to the circular groove 5 on the side close to the base 1. The connecting end 6 is inserted into the circular groove 5 and can rotate in the circular groove 5.
[0032] Furthermore, multiple slots 7 are evenly arranged around the circular groove 5 on the end face of the base 1, and several buckles 8 are provided on the side wall of the connecting end 6 of the outer shell 401, which are connected to the slots 7 one by one. After the connecting end 6 of the outer shell 401 is inserted into the circular groove 5, the buckles 8 are moved into the corresponding slots 7 by rotating the outer shell 401, thereby realizing the positioning of the dispersion component 4, which facilitates the disassembly and assembly of the dispersion component 4.
[0033] Furthermore, in order to improve the installation stability of the dispersion component 4, both the slot 7 and the buckle 8 are made of magnets. In this embodiment, N35 grade neodymium magnets (diameter Φ3mm, magnetic attraction force ≥8N) can be used to prevent the dispersion component 4 from shifting and falling out due to the impact of unstable oxygen flow.
[0034] Example 3: Based on Example 1, further, like Figure 3 and Figure 4 As shown, the outer casing 401 has several pins 11 inside, and the inner filter element 402 has several connecting ears 12 matching the number of pins 11 on its edge. The connecting ears 12 have pin holes that mate with the pins 11. The pin holes allow for quick disassembly and assembly of the inner filter element, facilitating replacement.
[0035] Example 4: Based on any of the above embodiments, further, like Figure 2 As shown, a differential pressure sensor 9 is also fixedly installed at the center of the outer diffusion plate 403. The differential pressure sensor 9 can detect the pressure difference between the space pressure between the inner filter element 402 and the outer diffusion plate 403 and the ambient pressure. Based on the detected pressure difference value, it can be linked with the alarm device to indicate whether to replace the filter element. When the differential pressure sensor 9 triggers the alarm, the diffusion assembly 4 can be directly peeled off to replace the filter element and clean the diffusion mesh on the outer diffusion plate 403.
[0036] Example 5: Based on any of the above embodiments, further, like Figure 2 As shown, a mounting bracket 10 for mounting a diffusion fan is provided on the end face of the outer casing 401 near the outer diffusion plate 403. A diffusion fan can be added through the mounting bracket 10 to diffuse the oxygen at the outlet of the outer diffusion plate 403, thereby improving the oxygen diffusion effect at the oxygen outlet.
[0037] Example 6: Based on any of the above embodiments, further, like Figure 2 As shown, an isolation net 3 is also installed at the oxygen outlet of the oxygen cylinder 13. The isolation net 3 can isolate large impurity particles or foreign objects from the oxygen inlet pipe.
[0038] The working principle of this utility model is as follows: Installation stage: The inner filter element 402 is connected to the inner side of the outer shell 401 through the pin 11. Then the entire diffusion assembly 4 is inserted into the circular groove 5 on the base 1 through the connecting end 6. The outer shell 401 is rotated according to the opening position of the slot 7 on the base 1 so that the buckle 8 on the outer shell 401 is screwed into the slot 7. The slot 7 and the buckle 8 are positioned by magnetic adsorption. Working phase: After the oxygen supply equipment is turned on, oxygen enters the oxygen outlet cylinder, and then enters the inner filter element 402 from the oxygen outlet to filter out fine impurities and dust in the gas. Then, it enters the room through the diffusion mesh on the outer diffusion plate 403 to distribute oxygen. Replacement phase: After the diffusion terminal has been used for a period of time, remove the diffusion assembly 4, replace the inner filter element 402 and clean the diffusion mesh on the outer diffusion plate 403, and then reinstall it in the same way, and the diffusion terminal can continue to operate.
[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
