[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A structural schematic diagram of a preferred embodiment of a wall-type multifunctional negative pressure precision storage tank provided by the utility model; Figure 2 for Figure 1 A structural cross-sectional view of the gas storage tank and the filter box shown; Figure 3 for Figure 1 A rear view of the structure of the gas tank shown; Figure 4 for Figure 2 A schematic diagram of the structure at A in the middle is an enlarged view. The wall-mounted multifunctional negative pressure precision storage tank includes an air intake protection mechanism 2 arranged inside the gas storage tank 1, the air intake protection mechanism 2 is used to sterilize the gas inside the gas storage tank 1, the top of the gas storage tank 1 is connected to a central negative pressure pipe 3, one side of the gas storage tank 1 is connected to a shunt gas supply mechanism 6, the shunt gas supply mechanism 6 is used for multi-pipeline gas supply to prevent single-pipeline gas supply blockage, and one side of the top of the gas storage tank 1 is connected to a filter box 8; the air intake protection mechanism 2 includes a connecting block 21 arranged at the bottom of the inner cavity of the gas storage tank 1, an ozone-free ultraviolet lamp 22 is inserted inside the connecting block 21, a transparent cover 23 is connected to the top of the connecting block 21, and a vent hole 24 is opened on the connecting block 21.

[0022] The air holes 24 are provided on the connecting block 21 to facilitate the internal air of the transparent cover 23 to communicate with the outside, thereby preventing the transparent cover 23 from being sealed internally and causing the transparent cover 23 to burst due to the expansion of gas due to the increase of temperature.

[0023] In the specific implementation process, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the split flow gas delivery mechanism 6 includes a main flow pipe 61 connected to one side of the gas storage tank 1 , and a manual control valve 62 is provided on the main flow pipe 61 .

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both sides of the main flow pipe 61 are connected to the branch pipe 63, the branch pipe 63 is provided with a solenoid valve 64, and the top of the filter box 8 is connected to the air discharge pipe 65.

[0025] It should be noted that: under normal circumstances, when the wavelength of the ultraviolet sterilization lamp is less than 200nm, it will react with the oxygen in the gas tank 1 to produce ozone. The ozone cannot be filtered by the filter box 8 and will be directly ingested by the human body, causing harm. By utilizing the 254nm wavelength unique to the ozone-free ultraviolet lamp 22, ozone is prevented from being generated. The transparent cover 23 is made of quartz glass with good light transmittance to avoid insufficient light transmittance and the situation where ultraviolet rays cannot penetrate the transparent cover 23. The gas tank 1 is connected to the central negative pressure pipe 3, the filter box 8 and the gas tank 1 are a cast integral part, the connecting block 21 is connected to the internal thread of the gas tank 1 and is sealed, the ozone-free ultraviolet lamp 22 is keyed to the connecting block 21, the transparent cover 23 and the connecting block 21 are a cast integral part, the mainstream pipe 61 is flange-connected to the gas tank 1, the mainstream pipe 61 is flange-connected to the shunt pipe 63, the solenoid valve 64 is flange-connected to the shunt pipe 63, and the manual control valve 62 is flange-connected to the mainstream pipe 61.

[0026] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a one-way valve 4 is connected to the central negative pressure pipe 3, a pressure gauge 5 is arranged on the top of the gas storage tank 1, and a controller 10 is arranged on the gas storage tank 1.

[0027] By setting a one-way valve 4 on the central negative pressure pipe 3, in order to prevent the gas in the gas storage tank 1 from returning to the central negative pressure pipe 3 and causing pollution to the pipe, the controller 10 is a logic controller.

[0028] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a through hole is opened on one side of the filter box 8, and an insert block 7 is inserted inside the through hole. A filter screen 12 is connected to one side of the insert block 7, and a sealing ring 13 is provided on one side of the insert block 7.

[0029] By providing the plug block 7 on one side of the filter screen 12, the filter screen 12 can be replaced with a new one after a period of use. By providing the sealing ring 13 on one side of the plug block 7, the gap between the plug block 7 and the filter box 8 can be reduced to improve the sealing performance.

[0030] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a plug plate 9 is connected to one side of the gas storage tank 1, and a connecting back plate 11 is sleeved on the plug plate 9.

[0031] It is convenient to insert the plug board 9 into the interior of the connecting backboard 11 and hang it on the wall.

[0032] It should be noted that: the one-way valve 4 is flange-connected to the central negative pressure pipe 3, the pressure gauge 5 is flange-connected to the gas tank 1, the mesh number of the filter screen 12 is 200 meshes, the filter screen 12 is movably inserted in the interior of the plug block 7, the interior of the filter box 8 is provided with a groove for use with a sealing ring 13, the sealing ring 13 is inserted in the interior of the groove, the plug block 7 is adhered and connected to the sealing ring 13, the plug block 7 and the filter box 8 are fixed and limited by bolts, the plug plate 9 and the gas tank 1 are a cast-in-one piece, the connecting back plate 11 is sleeved on the plug plate 9, and the connecting back plate 11 is fixed to the wall by bolts.

[0033] The working principle of the wall-type multifunctional negative pressure precision storage tank provided by the utility model is as follows:

[0034] When in use, the connecting back plate 11 is fixed to the wall by bolts, and the plug plate 9 on the back of the gas tank 1 is inserted into the inside of the connecting back plate 11. Oxygen enters the inside of the gas tank 1 through the central negative pressure pipe 3. The ozone-free ultraviolet lamp 22 inside the gas tank 1 sterilizes the oxygen inside the gas tank 1 by irradiating ultraviolet rays of a specific wavelength. Since the wavelength of the ozone-free ultraviolet lamp 22 does not meet the reaction conditions of oxygen, oxygen will not react with ultraviolet rays to produce ozone. In order to avoid that the temperature inside the transparent cover 23 will increase with the ozone-free ultraviolet light, the ozone-free ultraviolet lamp 22 will not react with the ultraviolet light to produce ozone. The line lamp 22 rises when it works, and the gas inside the transparent cover 23 expands. The through hole opened on the connecting block 21 helps the inside of the transparent cover 23 to communicate with the outside. The sterilized oxygen enters the interior of the filter box 8 through the main flow pipe 61, and passes through the 200-mesh filter 12. The filter 12 can filter out most of the fine particles in the oxygen. To prevent the main flow pipe 61 from being blocked, the controller 10 can open the shunt pipe 63 through the solenoid valve 64. The shunt pipe 63 transports oxygen to the interior of the filter box 8, and then transports it to the patient through the vent pipe 65.
