Technical Field

[0002] The invention relates to a gas processing component and a device, and in particular to a gas filtering component and a gas filtering device. Background Art

[0003] The existing gas filter assembly and filter device are usually assembled on the side or bottom, which is inconvenient to operate and cannot meet the requirements of structural sealing of the filter device with multiple airflow turns. Summary of the invention

[0004] The object of the present invention is to provide a gas filter assembly, comprising a box-shaped shell, the shell having a top, a bottom, and a side, at least one filter component is arranged in the inner cavity of the shell, the peripheral part of the filter component is sealed and connected to the inner surface of the shell, and the filter component divides the inner cavity of the shell into an air inlet cavity and an air outlet cavity, characterized in that an air inlet of the shell connected to the air inlet cavity is arranged on the side and / or bottom of the shell, and an air outlet of the shell connected to the air outlet cavity is arranged on the side and / or bottom of the shell; the top of the shell is sealed to the outside; and the top and / or bottom of the shell are provided with a shell sealing body protruding and / or recessed in the outer surface of the shell.

[0005] The filter component can be in the shape of a strip or a cylinder, and is formed by stacking or folding filter membrane materials.

[0006] The shell sealing body may be in the shape of a strip frame, which may be an independent component connected to the shell or a structural feature on the shell, and may be a rectangular, annular or irregular shaped sealing strip frame, which may be an elastomer or a hard material that seals with the elastomer.

[0007] There are no air inlets or outlets on the top of the filter assembly housing, which facilitates vertical plugging and unplugging of the filter assembly.

[0008] When a block-shaped filter component folded from a filter membrane material is used, the shell is provided with continuous or discontinuous limiting ribs protruding from the inner surface of the shell. The limiting ribs assist the shell in positioning the block-shaped filter component at a preset position in the inner cavity of the shell and restrict the flow of adhesive; the area enclosed by the continuous limiting ribs is more conducive to the injection of adhesive, avoiding the loss of adhesive before solidification, ensuring that a sufficient amount of adhesive is in full contact with the folded side of the filter membrane material of the filter component, and better sealing the filter component and the shell as a whole.

[0009] An optimized solution is that two filter components are arranged vertically and not close to each other in the inner cavity of the shell, forming two air inlet cavities opened on the side of the shell and two shell air inlets connected to the respective air inlet cavities, the space between the two filter components is the air outlet cavity, and the shell air outlet opened at the bottom of the shell is connected to the air outlet cavity; the vertical refers to the vertical relative to the top plane of the shell.

[0010] Another structure is that a continuous shielding rib is provided on one side of the shell cavity of the shell air outlet between two vertically arranged filter components at the bottom of the shell to prevent unsolidified adhesive from flowing into the shell air outlet during adhesive pouring.

[0011] To facilitate the insertion and removal of the filter assembly, a component is provided on the top of the shell to facilitate the use of fingers or tools to pull it upwards. The component may be an external handle or may be formed by the structure of the top of the shell itself.

[0012] A gas filter device using the above-mentioned gas filter component includes a box body with a accommodating space, the box body is provided with an air inlet and an air outlet, the box body is provided with a first accommodating chamber that can accommodate a fan, and the box body is provided with a second accommodating chamber for accommodating the above-mentioned gas filter component. The gas filter component is inserted through the top opening of the second accommodating chamber, and the shell seal on the gas filter component is sealed and connected with the corresponding first box body seal on the second accommodating chamber; the first box body seal can be an elastic strip frame-shaped seal, which can be provided with a groove, and the hard gas filter component shell seal is pressed into the groove with interference fit to achieve a sealed connection.

[0013] Furthermore, it also includes a third accommodating chamber, the first accommodating chamber of the box body is located between the second accommodating chamber and the third accommodating chamber; the air inlet of the box body is opened at the top of the box body and communicates with the third accommodating chamber, and the third accommodating chamber accommodates the gas regulating component.

[0014] In a preferred solution, the fan is suspended on the top of the first accommodating chamber.

[0015] In order to better regulate the gas, one or more gas regulating components are placed in the third accommodating chamber of the box body, including but not limited to a gas adsorption component, a gas filtering component, a carbon dioxide decomposition component, and an oxygen generation component.

[0016] Furthermore, a gas humidification module is connected to the air outlet of the box.

[0017] The beneficial effects of the present invention are: the top of the gas filter assembly is sealed to the outside, the side or bottom is for air intake and outlet, the top is applied and then the assembly can be vertically taken out and installed, the operation is convenient and the assembly can be sealed with the matching gas filter device.

[0029] Embodiment 1:

[0030] like Figure 1A , 1B As shown, a gas filter assembly includes a box-shaped shell 1, the shell 1 has a top 11, a bottom 12, and a side 13. A strip-shaped filter component 2 is arranged in a vertical position in the shell cavity 10. The vertical refers to the verticality relative to the plane of the shell top 11. The filter component 2 divides the shell cavity 10 into an air inlet cavity 101 and an air outlet cavity 102. The shell air inlet 101a connected to the air inlet cavity 101 is opened in the shell side 13, and the shell air outlet 102b connected to the air outlet cavity 102 is opened in the shell bottom 12. The filter component 2 is formed by a membrane material for filtering gas particles, which is folded back and forth in a "Z" shape in sequence. The upper and lower parts of the "Z"-shaped folding of the filter component 2 are sealed to the inner surfaces of the shell top 11 and the shell bottom 12 respectively by adhesive G, and the peripheral part of the side of the filter component 2 is sealed to the inner surface of the shell side 13 by adhesive G. As shown Figure 1AAs shown in the enlarged part, the bottom of the shell is provided with a continuous limiting rib 141 protruding from the inner surface 14 of the shell. The limiting rib 141 assists the shell in positioning the block-shaped filter component 2, especially one side of the "Z"-shaped fold, and restricts the possible free flow of the adhesive G before solidification, ensuring that the adhesive G fully enters the edge of the "Z"-shaped folded part of the filter membrane material to achieve a reliable seal. The continuous limiting rib 141 can also prevent the adhesive G from flowing into the shell outlet 102b before solidification due to its high shielding effect; in order to facilitate the removal of the gas filter assembly from the matching filter device (not shown), the top 11 of the shell is provided with a component 111 that is convenient for fingers or tools to apply force and pull upwards. This example shows an external handle 111, which can also be an inwardly recessed or protruding structure on the top of the shell. ; In order to achieve a sealed connection between the gas filter assembly and the matching filter device, the top 11 and the bottom 12 of the shell 1 are provided with a strip-frame-shaped shell sealing body 151 protruding from the outer surface 15 of the shell, wherein the top 11 of the shell is a first shell sealing body 151a protruding in a rectangular strip-frame shape, and the bottom 12 of the shell is a second shell sealing body 151b protruding in a ring-shaped strip-frame shape; when the gas filter assembly of this embodiment is in use, the top 11 of the shell faces upward, and the gas enters from the air inlet 101a on the side 13 of the shell. After being filtered by the filter component 2, the gas flows out from the air outlet 102b arranged at the bottom 12 of the shell, and the gas filter assembly is suitable for vertical plugging and unplugging; in order to ensure the accurate plugging and unplugging position, the top 11 of the shell is provided with an angled area 112 to prevent the shell 1 with a rectangular cross-section from being plugged and unplugged incorrectly.

[0031] Example 2: Figure 2A , 2B As shown, the biggest difference from the previous embodiment is that the housing inner cavity 10 is provided with two filter components 2 arranged vertically and not close to each other, forming two air inlet cavities 101 opened on the side 13 of the housing and two housing air inlets 101a respectively connected to the respective air inlet cavities, the space between the two filter components 2 is the air outlet cavity 102, and the housing air outlet 102b opened on the bottom 12 of the housing is connected to the air outlet cavity 102; Figure 2C The shell 1 is formed by sealingly connecting an upper shell and a lower shell by welding or bonding. A continuous limiting rib 141 is provided on the lower shell to form an adhesive G injection groove, which helps to ensure that the edge of the "Z"-shaped folded part of the filter membrane material is reliably sealed with the inner surface of the shell. Compared with Example 1, the parallel arrangement of the filter components 2 in this example can multiply the filtration area, increase the dust holding capacity and reduce the filtration resistance.

[0032] Example 3: Figure 3As shown, the biggest difference from Example 2 is that a continuous shielding rib 142 protrudes from the air outlet 102b of the lower shell toward the inner cavity of the inner shell to prevent the unsolidified adhesive G from flowing into the shell air outlet 102b when the adhesive G is poured. Continuous limiting ribs 141 protrude from the periphery of the lower shell to assist in sealing the edges of the "Z"-shaped folded portions of the filter membrane materials of the two filter components 2. In order to clearly show the lower shell structure, the filter component 2 on the right side of the figure is partially cut away.

[0033] Example 4: Figure 4A , 4B As shown, the biggest difference from the aforementioned embodiment is that the filter component 2 is cylindrical, and the top and bottom of the edge of the "Z"-shaped folded part of the filter membrane material are sealed and connected to the inner surfaces of the top 11 and the bottom 12 of the shell respectively. The internal space of the cylindrical filter component 2 is the air outlet cavity 102, and the space between the inner surface of the shell 1 and the outer surface of the cylindrical filter component 2 is the air inlet cavity 101. At the air outlet 102b of the lower shell, two continuous annular shielding ribs 142 protrude toward the inner cavity of the shell to prevent the adhesive G that has not yet solidified from flowing into the air outlet 102b of the shell when the adhesive G is poured. The cylindrical filter component 2 helps to increase the filtration area and reduce the airflow resistance; when the distance to the filter membrane material is close, in the present invention, the functions of the limiting ribs and the shielding ribs can be combined.

[0034] Example 5: Figure 5A , 5B As shown, a gas filter device using the gas filter assembly in the above-mentioned embodiment 3 includes a box body 3 with a storage space, which is placed horizontally when in use, and the box body 3 is provided with an air inlet 301 opened upward and an air outlet 302 opened downward, and the box body 3 is provided with a first storage chamber 300, and a fan F is suspended at the top of the first storage chamber 300. Experiments show that the fan F suspended at the top of the first storage chamber 300 has better operating efficiency and the lowest noise in the filtering device; the box body 3 is provided with a second storage chamber 304 for accommodating the above-mentioned gas filter assembly, and the gas filter assembly housing 1 is placed through the top opening 3040 of the second storage chamber 304, and the first housing seal 151a on the top 11 of the gas filter assembly is in contact with the corresponding housing seal 151a on the top 31 of the second storage chamber The first box seal 3041 is sealed and connected. This example shows the first box seal 3041 made of elastic silicone rubber or TPE, etc., which is an integral strip frame with a groove-shaped cross-section. The hard gas filter assembly shell seal 151 is pressed into the groove with interference fit to achieve a sealed connection; the second shell seal 151b on the bottom 12 of the gas filter assembly is sealed and connected with the corresponding second box seal 321 on the bottom 32 of the second accommodating cavity; the box 3 is also provided with a third accommodating cavity 303 located on the other side of the first accommodating cavity 300, and the two are connected through the fan front channel 305. The box air inlet 301 is opened at the top 31 of the box and communicates with the third accommodating cavity 303. The third accommodating cavity 303 accommodates a gas regulating component 4 placed horizontally. Figure 5AA gas adsorption component 41, a gas filtering component 42, and a carbon dioxide decomposition component 43 are shown, and an oxygen generating component, a hydrogen generating component, etc. may also be used; the arrow in the figure indicates the direction of gas flow; the gas filter assembly shell 1 can be taken out of the second accommodating chamber 304 of the box body 3 by pulling the handle 111 on the gas filtering assembly shell 1, and the handle on the gas regulating component 4 is omitted in the figure.

[0035] Example 6: Figure 6 As shown, the difference from Example 5 is that a gas humidification module 5 that can be filled with humidification liquid is connected to the air outlet 302 of the box body through the rear channel 306 of the filter component, and the top 51 of the humidification module is provided with an openable and closable cover 511 to seal the liquid filling port. The arrow indicates the direction of air flow. The gas enters the box body through the gas regulating component 4, and enters the humidification module 5 through the gas filter component. Finally, the humidified airflow flows out from the air outlet 50 of the gas humidification module 5; the description of the control module, display module, etc. that may be involved in the present invention is omitted.
