Description

Technical Field

[0001] The invention belongs to the technical field of gas filling facilities, and in particular relates to a health-care oxygen tank oxygen filling device. Background Art

[0002] Oxygen is a major element for the human body to carry out metabolism and maintain life. Breathed oxygen is converted into usable oxygen in the human body, which is called blood oxygen. The blood carries blood oxygen to transport energy to the whole body, and the amount of blood oxygen transported is closely related to the working state of the heart and brain. The normal human body's blood oxygen saturation is maintained above 95% to ensure that the body has sufficient oxygen supply. If the blood oxygen content is too low, it is easy to cause insufficient oxygen supply to the body, which will affect metabolism and physiological functions. On the contrary, too high blood oxygen may also cause aging of cells in the body, so maintaining a suitable blood oxygen level is very important to ensure human health.

[0003] As people's awareness of self-health continues to increase, oxygen is no longer just a "patent" used by medical departments for clinical patients. Outdoor sports, mountaineering, tourism, drivers, athletes, pregnant women, surgeons, middle-aged and elderly people, chronic patients with cardiovascular and respiratory systems, medical rehabilitation groups, office white-collar workers, and even beauty salons are not uncommonly equipped with health oxygen tanks. In particular, in recent years, health oxygen tanks filled with oxygen can be purchased on demand in places such as pharmacies, shopping malls, and supermarkets. Since the basic structure of the aforementioned health oxygen tank can be fully understood by reading Chinese patents such as CN2726620Y (portable atomizing health oxygen tank), CN2901006Y (ventilation type pressure reduction regulating device), and CN104984453B (full-automatic oxygen supply device for health oxygen tank), which are not limited to the examples and are designed by the inventor of this application, it will not be repeated.

[0004] According to professional common sense, many health oxygen tanks are used in rotation, just like the liquefied gas tanks used for cooking in daily life. When they are used up, they are replaced to save usage costs and avoid wasting resources.

[0005] The model of filling the health oxygen tank with oxygen and then distributing the oxygen-filled health oxygen tank to various sales points is an offline business model (referred to as the "O2O" model). It is based on this model, coupled with the increasing use of health oxygen tanks, that the development of an oxygen filling device as an oxygen filling station has good positive significance. Specifically, the oxygen filling device as an oxygen filling station can ensure the stability and reliability of the oxygen supply, because the centralized oxygen supply system can ensure uninterrupted (continuous supply) oxygen by centrally installing the oxygen supply equipment and system in a specific area and transporting it to the point of use through pipelines or storage tanks; saving space and labor costs; reducing operating costs; improving safety; facilitating management and monitoring; and having a wide range of applicable scenarios, etc. In view of the fact that no relevant technical information on the health oxygen tank oxygen filling device that can fully reflect the aforementioned positive significance has been found in the Chinese and foreign patents and non-patent literature disclosed so far, the applicant has made beneficial explorations and repeated designs, and formed the technical solution to be introduced below.

[0022] See you next time Figure 1 and Figure 2 As a first embodiment, the aforementioned oxygenation delivery pipe 3 is arranged in the form of a single piece along the height direction of the aforementioned left frame 1 and the right frame 2 from top to bottom or from bottom to top between the opposite sides of the left and right frames 1 and 2, and the upper and lower adjacent oxygenation delivery pipes 3 are both parallel to each other and spaced from each other; as a second embodiment, the aforementioned oxygenation delivery pipe 3 is arranged in the form of two front-to-back parallel pairs along the height direction of the aforementioned left frame 1 and the right frame 2 from top to bottom or from bottom to top between the opposite sides of the aforementioned left and right frames 1 and 2, and the upper and lower adjacent oxygenation delivery pipes 3 are also both parallel to each other and spaced from each other.

[0023] The applicant has cited two specific implementation methods above. Figure 1 and Figure 2 The second embodiment is shown in the figure. Of course, the present invention is not limited to the two embodiments listed above. When the first embodiment is adopted, the oxygen flow transition pipe 41 is formed into an interface for connecting with the oxygen delivery pipe 3. When the second embodiment is adopted, the oxygen flow transition pipe 41 is formed into an interface for connecting with the oxygen delivery pipe 3. Figure 1 As shown, the oxygen flow transition pipe 41 is formed into two interfaces for connecting to two oxygenation delivery pipes 3 respectively. Figure 1 As shown, in the second embodiment, the oxygen flow splitting transition pipe 41 is in a U-shape with two interfaces and tilted 90 degrees to the right.

[0024] In addition, in the case of the second embodiment, there are three pairs of upper, middle and lower oxygen delivery pipes 3, that is, a total of six oxygen delivery pipes 3. According to professional common sense, if the distance between the left and right frames 1 and 2 is reasonably increased, the number of oxygen delivery pipes 3 can be increased accordingly, such as increasing the three pairs to four or five pairs, etc. In addition, in the second embodiment, fifteen oxygen outlet nozzles 33 are shown to be extended in the length direction of each oxygen delivery pipe 3. Since each oxygen outlet nozzle 33 corresponds to a health oxygen tank oxygenation positioning control mechanism 5, there are ninety oxygen outlet nozzles 33 and corresponding health oxygen tank oxygenation positioning control mechanisms 5 in the second embodiment. The above number is also not affected by the embodiment, because if the distance between the left and right frames 1 and 2 is reasonably increased, the length of the oxygen delivery pipe 3 can be increased accordingly, and the number of the corresponding oxygen outlet nozzles 33 and the number of the health oxygen tank oxygenation positioning control mechanisms 5 connected thereto can also be increased adaptively. Furthermore, according to professional common sense, the number of oxygen outlet nozzles 33 is proportional to the number of oxygen filling positioning control mechanisms 5 of the health oxygen tank, and can be changed according to the requirements of the application scenario.

[0025] Please see the key Figure 1, in this embodiment, the aforementioned left frame body 1 includes a left front column 11 of the frame body, a left rear column 12 of the frame body, a left top cross beam 13 of the frame body, a left bottom cross beam 14 of the frame body, a first middle cross beam 15 of the left frame body, and a second middle cross beam 16 of the left frame body. The left top cross beam 13, the first middle cross beam 15 of the left frame body, the second middle cross beam 16 of the left frame body, and the left bottom cross beam 14 are fixedly connected in sequence from top to bottom between the opposite sides of the left front and rear columns 11 and 12 of the frame body, so that the left frame body 1 forms a structure in the shape of the Chinese character "mu". The aforementioned right frame body 2 includes a right front column 21 of the frame body, a right rear column 22 of the frame body, a right top cross beam 23 of the frame body, a right bottom cross beam 24 of the frame body, a first middle cross beam 25 of the right frame body, and a second middle cross beam 26 of the right frame body.

[0026] According to professional common sense, the forms of the above-mentioned left and right frame bodies 1 and 2 are not limited by this embodiment either. For example, when the heights of the left and right frame bodies 1 and 2 need to be increased accordingly, then the first middle cross beam 15 of the left frame body and the first middle cross beam 25 of the right frame body are adaptively increased.

[0027] In Figure 1 and Figure 2 it is also shown that the L-shaped fixing plate 81 is adopted and the left and right ends of the connecting beam 8 of the health oxygen tank oxygen filling fixing frame are respectively fixed to the opposite sides of the aforementioned left and right frame bodies 1 and 2 by means of the L-shaped fixing plate screw 811. For example, the left and right ends of a pair of connecting beams 8 of the health oxygen tank oxygen filling fixing frames located in the upper part are respectively fixed to the opposite sides of the left and right top cross beams 13 and 23 of the frame body. Since the fixing methods of the left and right ends of the other connecting beams 8 of the health oxygen tank oxygen filling fixing frames in the middle and lower parts can be fully understood by analogy, the applicant will not elaborate one by one.

[0028] From Figure 1 and Figure 2 as shown, a left frame body traveling wheel 141 with a braking function is provided at the front bottom and the rear bottom of the front end of the aforementioned left frame body bottom cross beam 14, and a right frame body traveling wheel 241 with a braking function is provided at the front bottom and the rear bottom of the front end of the aforementioned right frame body bottom cross beam 24.

[0029] In order to ensure safety, the pressure transmitter 32 is an explosion-proof pressure transmitter; the solenoid valve 411 is an explosion-proof solenoid valve; a relief valve 43 is provided at the upper end of the oxygen distribution pipe 4, and the relief valve 43 is an explosion-proof relief valve. Since the working mechanism of the relief valve 43 and the pressure transmitter 32 belongs to the known technology, the applicant will not explain it in detail.

[0030] Still see Figure 1 and Figure 2 The aforementioned human-machine interface operation controller 7 is arranged on a panel 9, which is fixed to the upper part of the aforementioned left frame 1, and a pressure gauge 91 and a group of start-stop control switches 92 are arranged on the panel 9, the pressure gauge 91 is connected to the aforementioned oxygen introduction distribution pipe 4, and the pressure gauge 91 reveals the oxygen pressure introduced into the oxygen distribution pipe 4, that is, reveals the oxygen pressure of the oxygen supply source, because the oxygen supply source start-stop control valve 421 is normally open, and the pressure gauge 91 and a group of start-stop control switches 92 are electrically connected to the human-machine interface operation controller 7, and the aforementioned group of start-stop control switches 92 are explosion-proof start-stop control switches; the aforementioned electrical box 6 is fixed on the electrical box bracket 61, and the electrical box bracket 61 is fixed to the left end of the supporting fixed beam 10 at the lower part of the aforementioned frame.

[0031] Please see the key Figure 3 And combined with Figure 1 and Figure 2 The aforementioned oxygen filling positioning control mechanism 5 for the health care oxygen tank comprises an oxygen filling fixing frame 51 for the health care oxygen tank, an oxygen filling opening and closing valve 52 for the health care oxygen tank and a clamping bolt 53 for the health care oxygen tank. The oxygen filling fixing frame 51 for the health care oxygen tank is fixed to the aforementioned oxygen filling fixing frame connecting beam 8 for the health care oxygen tank, and the oxygen filling fixing frame 51 for the health care oxygen tank has an oxygen tank neck insertion cavity 511. The opening and closing valve inlet 521 of the oxygen filling opening and closing valve 52 for the health care oxygen tank is connected and communicated with the aforementioned oxygen outlet nozzle 33, and the opening and closing valve outlet 52 of the oxygen filling opening and closing valve 52 for the health care oxygen tank is connected and communicated with the aforementioned oxygen outlet nozzle 33. The opening 522 is inserted into the cavity 511 toward the neck of the aforementioned health care oxygen tank. The aforementioned health care oxygen tank oxygen filling on-off valve 52 is controlled by an on-off valve operating hand wheel 523 to connect or block (on / off) the on-off valve air inlet 521 and the on-off valve air outlet 522. The health care oxygen tank clamping bolt 53 is threadedly arranged on the aforementioned health care oxygen tank oxygen filling fixing frame 51 at a position corresponding to the on-off valve air outlet 522, and a clamping bolt operating disk 531 is arranged at the end of the health care oxygen tank clamping bolt 53 away from the health care oxygen tank oxygen filling fixing frame 51.

[0032] The side of the aforementioned health care oxygen tank oxygenation fixing frame 51 facing the aforementioned health care oxygen tank oxygenation fixing frame connecting beam 8 is fixed to the health care oxygen tank oxygenation fixing frame connecting beam 8 through the health care oxygen tank oxygenation fixing frame connecting plate 512.

[0033] In this embodiment, the oxygen filling opening and closing valve 52 of the foregoing health care oxygen tank is an explosion-proof valve; the oxygen filling fixing frame 51 of the foregoing health care oxygen tank has a rectangular structure of Chinese characters.

[0034] Please refer to Figure 4 and combine with Figures 1 to 3 , when it is necessary to fill gaseous oxygen into the health care oxygen tank 20 shown in Figure 4 , the neck of the health care oxygen tank 20 to be filled with oxygen is inserted into the foregoing health care oxygen tank neck insertion cavity 511. The on-site operator rotates the clamping bolt operation panel 531, and then opens the health care oxygen tank filling opening and closing valve 52 by rotating the opening and closing valve operation handwheel 523. The oxygen filling conveying pipe 3 fills the health care oxygen tank 20 through its oxygen outlet nozzle 33. During this process, when the pressure in the oxygen filling conveying pipe 3 decreases, the solenoid valve 411 automatically opens and oxygen enters the oxygen filling conveying pipe 3. Since the foregoing oxygen supply source opening and closing control valve 421 is normally open, the oxygen (gaseous oxygen) in the oxygen supply source such as an oxygen storage tank or a similar device sequentially passes through the oxygen supply source connecting pipe 42, the introduced oxygen distribution pipe 4, the oxygen shunt transition pipe 41, the oxygen filling conveying pipe 3, the oxygen outlet nozzle 33, the opening and closing valve air inlet 521, and the opening and closing valve air outlet 522, and finally enters the health care oxygen tank 20 through the health care oxygen tank air inlet on the health care oxygen tank 20. When the oxygen filling is completed, the health care oxygen tank filling opening and closing valve 52 is closed by operating the opening and closing valve operation handwheel 523, and the clamping bolt operation panel 531 is loosened (unscrewed), and the health care oxygen tank 20 that has completed the oxygen filling is removed. Since the reusable health care oxygen tank 20 is usually equipped with a pressure gauge and corresponding adjustment switches, etc., when the pressure in the health care oxygen tank 20 reaches the set value and is revealed by its pressure gauge, the oxygen filling switch on the health care oxygen tank 20 will automatically close. Of course, the operator can also observe the reading of the pressure gauge of the health care oxygen tank 20 at the same time. If the pressure shown by the pressure gauge reaches the rated pressure, it can be considered that the health care oxygen tank 20 is full. During the use process, the foregoing pressure transmitter 32 can measure the pressure signal in the oxygen filling conveying pipe 3 and convert the pressure signal into an electrical signal and feedback it to the human-machine interface operation controller 7 to reflect the online monitoring of the oxygen pressure in the oxygen filling conveying pipe 3 to ensure safety. The function of the foregoing relief valve 43 is that when the pressure at the control point exceeds the set value, it will automatically discharge a certain amount of gas, that is, release the excess pressure to ensure safety.

[0035] To sum up, the technical solution provided by the present invention makes up for the deficiencies in the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
