[0038] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0039] See Figure 1-5 The utility model discloses a gas filtering device 1, which can be used for gas filtering of medical equipment, including a partition plate 13, a shell 11 and an upper cover 12, the upper cover 12 is buckled into the opening of the shell 11, the partition plate 13 is arranged in the shell 11, and the partition plate 13 is arranged perpendicular to the upper cover 12.

[0040] A plurality of air cavities 111 are provided in the upper cover 12 and the outer shell 11. The partition plate 13 is installed in the air cavities 111. The partition plate 13 contacts the outer shell 11 and the upper cover 12 respectively. The partition plate 13 is provided between any two of the air cavities 111. Specifically, a mounting groove 112 is provided in the opening of the outer shell 11. The shape of the mounting groove 112 matches that of the upper cover 12. The mounting groove 112 is used for snap-fit ​​installation of the upper cover 12. The height of the partition plate 13 is greater than or equal to the distance from the upper cover 12 to the bottom of the air cavity 111. When the upper cover 12 is snap-fitted and installed in the mounting groove 112, the top of the partition plate 13 contacts the upper cover 12. As an embodiment, three air cavities 111 are provided in the outer shell 11, but the number of air cavities 111 that can be provided in the outer shell 11 is not limited to three.

[0041] In particular, a filter component, such as a filter element, a solid absorbent, etc., can be placed in the air cavity 111. The filter components placed in each air cavity 111 can be the same or different, and can be specifically configured according to the current gas filtering requirements.

[0042] An air outlet pipe 113 and an air inlet pipe 114 are provided on the side wall of the shell 11, and any one of the air cavities 111 is provided with an air inlet 1111 and an air outlet 1112. The air inlet 1111 is connected to the air inlet pipe 114, and the air outlet pipe 113 is connected to the air outlet 1112. The number of the air outlet pipes 113 is the same as the number of the air outlets 1112, and the number of the air inlet pipes 114 is the same as the number of the air inlet ports 1111. Specifically, the outer shell 11 is provided with an outlet pipe 113 and an inlet pipe 114 connecting the internal air cavity 111 and the outside. Each air cavity 111 is provided with an independent air inlet 1111 and an air outlet 1112. The air inlet pipe 114 and the air outlet pipe 113 are connected to the air inlet 1111 and the air outlet 1112 respectively. The gas enters the air cavity 111 from the inlet pipe 114 and the air inlet 1111, and is output from the air outlet 1112 and the outlet pipe 113.

[0043] Specifically, the partition plate 13 divides the space within the housing 11 into multiple air cavities 111. Gas is input through the air inlet 1111 and output from the air outlet 1112 after passing through the air cavity 111. A filter assembly can be placed in any air cavity 111 to form a filter. The provision of multiple air cavities 111 can meet the needs of multiple gas filtration, enabling the gas supply equipment to filter multiple gases, avoiding the use of multiple gas filters for processing, reducing the tedious installation operation of connecting multiple gas filters, and improving the convenience of operation. It can be understood that the device inherits multiple independent air cavities 111. By connecting the air outlet 1112 between the air cavities 111 with the air inlet 1111, the need for multiple filters to filter in series can be met.

[0044] In particular, the paths between the various air cavities 111 can be set differently, that is, the gas enters from the air inlet 1111, passes through the air cavity 111, and is output again from the air outlet 1112. The paths of the gas in the various air cavities 111 can be set differently, so that the filtering paths of the gas are different.

[0045] As an embodiment, the upper cover 12 includes a sealing gasket 121. The shape of the sealing gasket 121 matches the mounting groove 112. The sealing gasket 121 can be placed in the mounting groove 112. The sealing gasket 121 is disposed in the air cavity 111, and the partition plate 13 abuts against the sealing gasket 121. Specifically, the outer periphery of the sealing gasket 121 contacts the inner wall of the outer shell 11, and the two surfaces of the sealing gasket 121 contact the upper cover 12 and the partition plate 13 respectively. This can block the gaps between the upper cover 12 and the partition plate 13, as well as between the upper cover 12 and the outer shell 11, preventing gas leakage and ensuring the airtightness of the air cavity 111. In addition, the partition plate 13 separates the air cavities 111, and the sealing gasket 121 can prevent the spaces between the air cavities 111 from being connected.

[0046] The device includes a fastener 15 , the housing 11 is provided with a screw hole 116 , the threaded structure provided on the fastener 15 matches the screw hole 116 , the upper cover 12 is provided with an opening 122 , and the fastener 15 passes through the opening 122 and is connected to the screw hole 116 .

[0047] Specifically, the upper cover 12 is provided with an opening 122, and the sealing gasket 121 is provided with a hole 1211 corresponding to the opening 122. The fastener 15 passes through the opening 122 and the hole 1211 and is connected to the screw hole 116, so that the upper cover 12 and the sealing gasket 121 are fixed in the installation groove 112. At the same time, the upper cover 12 and the sealing gasket 121 are supported on the partition plate 13 by the fastener 15, thereby avoiding the separation of the air cavities 111, preventing gas contact between the air cavities 111, and improving the air tightness in the air cavity 111.

[0048] In this embodiment, the fastener 15 is a self-tapping screw, but the type of the fastener 15 is not limited to the self-tapping screw used in this embodiment.

[0049] The device includes a detection member 14 connected to the housing 11 and positioned near the outlet pipe 113. The detection member 14 is a timing identification board that records and identifies the time the device has been in use. By performing a detection at the outlet pipe 113, the current device usage time can be obtained. Furthermore, the detection member 14 is mounted outside the housing 11 for easy maintenance and replacement.

[0050] As an embodiment, the detection element 14 may be a concentration detection sensor. The detection element 14 is disposed on the gas outlet pipe 113 and can detect the concentration of various contents of the outlet gas in the gas outlet pipe 113 .

[0051] The housing 11 includes filter cotton 115. The housing 11 is provided with an installation compartment. The filter cotton 115 is installed in the installation compartment. An installation compartment is provided between the air inlet 1111 and the air inlet pipe, and an installation compartment is provided between the air outlet 1112 and the air outlet pipe.

[0052] It can be understood that the installation compartment is installed inside the shell 11 and is arranged near the side wall where the air inlet 1111 and the air outlet 1112 are located. The installation compartment is set between the air inlet 1111 and the air inlet channel, and between the air outlet 1112 and the air outlet channel. The filter cotton 115 is installed in the installation compartment, thereby blocking the air inlet 1111 and the air inlet channel, and the air outlet 1112 and the air outlet channel, so that the gas entering the air cavity 111 and the output air cavity 111 are filtered by the filter cotton 115. The filtration efficiency is improved by combining the filter cotton 115 and the filter assembly in the air cavity 111.

[0053] The partition plate 13 is provided with reinforcing ribs 131, and the reinforcing ribs 131 are perpendicular to the body of the partition plate 13. There is a certain distance between each reinforcing rib 131. By placing filter materials or absorbents in adjacent reinforcing ribs 131, and placing different filter materials or absorbents in different intervals, the filter components composed in each air cavity 111 are different, and the filtering effects are different. The filter components are combined according to actual needs, thereby enhancing the filtering effect on the gas.

[0054] Optionally, the housing 11 is provided with a handle 16 on a side wall opposite to the air inlet 1111. Specifically, the housing 11 is provided with the handle 16, which can improve the convenience of moving the device when the device is moved.
