DETAILED DESCRIPTION

[0068] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be described in more detail below in conjunction with the accompanying drawings in the preferred embodiments of the present invention.

[0069] like Figure 1 , Figure 2 and Figure 3As shown, the embodiment of the utility model provides a gas processing device, including a housing 1, on which a first vent 111, a second vent 112 and a third vent 131 are provided; a gas processing component 2 is arranged in the housing 1 and is used to process the gas; a gas driving component 3 is arranged in the housing 1 and is used to drive the gas to enter the housing 1 through the first vent 111 and / or the second vent, and to be discharged from the third vent 131 after being processed by the gas processing component 2. Among them, the first vent 111 is used to connect to the additive molding device, and the second vent 112 is used to connect to the external gas.

[0070] It can be understood that when the first air vent 111 is opened and the second air vent 112 is blocked, only the second air vent 112 can take in air and be processed by the gas processing component 2; when the second air vent 112 is opened and the first air vent 111 is blocked, only the first air vent 111 can take in air and be processed by the gas processing component 2; when both the first air vent 111 and the second air vent 112 are opened, both the first air vent 111 and the second air vent 112 can take in air and be processed by the gas processing component 2 together.

[0071] Moreover, the first vent 111 and the second vent 112 can be connected to different positions or different devices correspondingly, so that the first vent 111 and the second vent 112 enter the gas of different positions or different devices, or the first vent 111 and the second vent 112 can be connected to the same position or the same device, so that the first vent 111 and the second vent 112 enter the gas of the same position or the same device to accelerate the processing speed of the gas at the position. The above can be selected according to actual needs when used, and this application does not limit it.

[0072] The gas processing device provided in the embodiment of the utility model can be a device capable of processing gas, for example, the gas processing device can be an air purifier, wherein the gas processing component 2 can be a device for purifying or filtering gas such as a filter element, which is used to filter or purify the gas entering the housing 1, and the gas driving component 3 can be a device capable of driving the flow of gas such as a fan. Moreover, the first vent 111 can be used to communicate with the exhaust port of the additive molding device to purify the gas output by the additive molding device, and the second vent 112 is connected to the air outside the gas processing device, such as the air in the user's room, to purify the indoor air.

[0073] The gas treatment device provided by the embodiment of the utility model has a first vent 111 and a second vent 112 on the shell 1, wherein the first vent 111 can be used to communicate with the exhaust port of the additive molding device, and the second vent 112 can be communicated with the air outside the gas treatment device. When the gas driving member 3 is started, the gas in the additive molding device and / or the gas outside the gas treatment device can enter the shell 1 through the first vent 111 and the second vent 112 respectively, and be discharged from the third vent 131 after being processed by the gas treatment member 2, so that the gas of the additive molding device can be processed, and the air outside the gas treatment device, such as indoor air, can be processed. Compared with the prior art, the gas treatment device provided by the embodiment of the utility model can process different gases, increase the function of the gas treatment device, improve its versatility, and be more convenient to use.

[0074] In order to improve the utilization rate of the gas processing unit 2, in some embodiments, see Figure 2 The gas processing component 2 includes an air inlet end 21; an air duct may be provided in the shell 1, one end of the air duct is connected to the first air vent 111 and the second air vent 112, and the other end of the air duct is connected to the air inlet end 21, and the air duct is used to guide the gas entering the shell 1 through the first air vent 111 and / or the second air vent to the air inlet end 21.

[0075] After the gas enters the gas inlet end 21 of the gas treatment component 2, the gas will enter the gas treatment component 2 through the gas inlet end 21, so that the gas treatment component 2 processes the air.

[0076] It is understandable that if the gas can directly enter the gas treatment component 2 through the inlet end of the gas treatment component 2 for treatment, the utilization rate of the gas treatment component 2 will be improved. For example, the gas to be filtered directly enters the filter element through the inlet end of the filter element, which will improve the utilization rate of the filter element and improve the filtering effect of the gas. In the above embodiment, an air duct is provided in the housing 1, and the air duct connects the first air vent 111, the second air vent 112 and the air inlet end 21 of the gas treatment component 2, so that the gas entering from the first air vent 111 and the second air vent 112 can directly enter the air inlet end 21 of the gas treatment component 2 through the air duct, thereby improving the utilization rate of the gas treatment component 2 and further improving the gas treatment effect.

[0077] The gas processing unit 2 may further include a gas outlet 22 corresponding to the gas inlet 21;

[0078] Buffer cotton is arranged on the side wall of the gas outlet end 22, and the buffer cotton extends along the axial direction of the gas treatment component 2. In the axial direction of the gas treatment component 2, the length of the buffer cotton can be 1cm to 10cm; and / or, the gas outlet end 22 is provided with a handle.

[0079] Among them, the air inlet end 21 and the air outlet end 22 can be located at both ends of the axial direction of the gas treatment component 2, and the buffer cotton is located on the side wall of the air outlet end 22. The gas treatment component 2 can be abutted against the inner wall of the shell 1 through the buffer cotton, which can prevent the gas treatment component 2 from shaking due to abnormal factors such as vibration of the device, thereby protecting the gas treatment component 2 and preventing it from being damaged. Moreover, when the air outlet end 22 is provided with both the buffer cotton and the handle, the buffer cotton can increase the friction between the shell 1 and the gas treatment component 2, so that the user can lift the shell 1 and the gas treatment component 2 together by holding the handle, which is convenient for moving the device. Specifically, the axial length of the gas treatment component 2 can be 1cm to 10cm to make it more reliable to use.

[0080] Of course, in the case where only a handle is provided at the gas outlet end 22, after the user fixes the housing 1, the user can hold the handle to pull out or put in the gas treatment component 2, which is convenient for disassembling the gas treatment component 2. It can be understood that by providing different buffer cottons, the friction between the buffer cotton and the housing 1 can be changed. In some cases, the gas treatment component 2 can be disassembled from the housing 1 by only pulling the handle without fixing the housing 1.

[0081] In some embodiments, the shell 1 may include a lower shell and an upper shell 13, the lower shell is detachably connected to the upper shell 13, a first channel connected to the airway is provided on the lower shell, and a second channel is provided on the upper shell. When the lower shell is connected to the upper shell 13, the first channel and the second channel are connected, the gas processing component 2 is provided in the first channel, and the gas driving component 3 is provided in the second channel.

[0082] When the gas processing device is in use, the first channel and the second channel are connected, and the gas driving member 3 starts to drive the gas flow to flow in the first channel and the second channel, so that the gas is processed by the gas processing member 2 and then discharged from the third vent 131. When the gas flows, the gas in the additive molding device connected to the first vent 111 and / or the external gas connected to the second vent 112 are sucked into the housing 1 for processing.

[0083] The upper shell 13 and the lower shell are detachably connected, which is convenient for disassembly and maintenance of the gas processing unit 2. The upper shell 13 and the lower shell can be connected by a quick-release method such as a snap connection to facilitate replacement of the gas processing unit 2.

[0084] In some embodiments, see Figure 2 and Figure 3The lower shell may include a first shell 11 and a second shell 12, the first shell 11 includes a first open end and a first closed end, the second shell 12 is provided with the aforementioned first channel, the two ends of the first channel respectively include a second open end and a third open end, that is, one end of the second channel may include the second open end, and the other end may include the third open end, the second shell 12 is provided in the first shell 11, the first shell 11 and the second shell 12 are connected, and the first closed end corresponds to the second open end, the first open end corresponds to the third open end, and a gap 14 is provided between the first shell 11 and the second shell 12; the air inlet end 21 is opposite to the second open end; the aforementioned second vent 112 is provided between the first open end and the third open end; a first vent 111 is provided on the first shell 11 between the first closed end and the second open end; the gap 14 is an airway.

[0085] According to the above embodiment, after the gas enters the gap 14 through the first vent 111 and / or the second vent 112, it can flow along the gap 14 to the second open end under the drive of the gas driving member 3, and then enter the gas processing member 2 through the inlet end 21, so that the gap 14 can guide the gas entering the shell 1 through the first vent 111 and / or the second vent to the gas driving member 3, and the gap 14 forms the aforementioned air channel, which has a simple structure and is reliable in use. Specifically, the first shell 11 can be a cylinder with one end closed and the other end open, and the second shell 12 can be a cylinder with both ends open, and the internal space thereof forms the first channel.

[0086] Among them, the size of the gap between the first shell 11 and the second shell 12 can be 3mm-30mm, specifically, the size can be 10mm, so as to ensure that the size between the two is not too large while ensuring the smooth flow of airflow; in the axial direction of the gas processing device, the size of the upper shell 13 can be 100mm-170mm, the size of the first shell 11 of the lower shell can be 230mm-300mm, and the size of the gas processing component 2 can be 170mm-250mm.

[0087] In some embodiments, see Figure 2 and Fig.10 A plurality of protrusions 113 are arranged inside the first closed end, and the plurality of protrusions 113 are evenly distributed along the circumference of the first closed end; and the second open end is supported by the plurality of protrusions 113. There are at least two protrusions 113.

[0088] Among them, the second open end is supported by multiple protrusions 113. On the one hand, it can be achieved that a gap 14 is maintained between the first closed end of the first shell 11 and the second open end of the second shell 12. On the other hand, since the multiple protrusions 113 are evenly distributed along the circumference of the first closed end, when the gas entering the gap 14 reaches the first closed end, it can enter the gas processing component 2 evenly in multiple ways under the blocking effect of the multiple protrusions 113, thereby avoiding excessive local air intake of the gas processing component 2 and increasing the load, thereby extending the service life of the gas processing component 2.

[0089] Specifically, the protruding member 113 may be a U-shaped member, one side of which is connected to the inner end surface of the first closed end, and the open end of which is connected to the inner side surface of the first closed end.

[0090] In some embodiments, see Figure 2 , Figure 3 and Fig.12 A mounting member 122 may be provided on the inner wall of the second shell 12 , and the distance between the mounting member 122 and the second opening end is less than or equal to 30 cm. The mounting member 122 is used to support the gas processing member 2 .

[0091] The gas processing component 2 can be supported on the mounting component 122 , which can facilitate the installation and fixation of the gas processing component 2 in the second housing 12 .

[0092] Among them, the mounting member 122 can be a boss protruding toward the inner center of the second shell 12 based on the inner wall of the second shell 12, and the boss can extend along the circumference of the second shell 12; the distance between the mounting member 122 and the second opening end can be less than or equal to 30mm, and the specific distance can be determined according to actual needs during implementation, and the present application does not limit it. Specifically, due to the setting of the aforementioned protrusion 113, there is enough space for gas circulation between the gas processing member 2 and the first closed end, and therefore, the distance between the mounting member 122 and the second opening end can be 0mm.

[0093] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The gas processing device may further include a cover body 4 , which is detachably covered in the first vent 111 to open or close the first vent 111 .

[0094] In some embodiments, see Figure 8 and Fig. 9 A mounting hole 114 is provided on the first shell 11; the cover body 4 may include a main body 41 and a plug-in column 42 connected to the main body 41, at least the plug-in column 42 is an elastic member, and the plug-in column 42 is plugged into the mounting hole 114; the main body 41 is detachably covered in the first vent 111.

[0095] In the above embodiment, the plug-in column 42 is an elastic member, and when the plug-in column 42 is interference-fitted in the mounting hole 114, the body 41 can be covered in the first vent 111 or detached from the first vent 111 to open or close the first vent 111. Of course, the body 41 and the plug-in column 42 can be integrally formed and are both elastic members, for example, the cover body 4 is a silicone cover, to improve the sealing performance of the first vent 111 when it is closed.

[0096] The plug-in column 42 and the hole wall of the mounting hole 114 may be interference fit; or, the size of the end of the plug-in column 42 may be larger than the size of other positions, so that after the end of the plug-in column 42 passes through the mounting hole 114, the plug-in column 42 can be snapped into the mounting hole 114.

[0097] In order to facilitate the cover body 4 to open or close the first vent 111, a first card slot connected to the first vent 111 may be provided on the first shell 11, and the cover body 4 may further include a first card block connected to the body 41, and when the cover body 4 is covered in the first vent 111, the first card block is engaged in the first card slot. When the cover body 4 needs to be opened, the first card block can be moved to separate the body 41 from the first vent 111; when the cover body 4 needs to be closed, the first card block can be aligned with the first card slot to cover the body 41 in the first vent 111, which is convenient for operation.

[0098] In some embodiments, see Figure 2 , Figure 4 and Figure 5 The outer peripheral wall of the third opening end is provided with a convex edge 121, which extends along the circumference of the third opening end and abuts against the inner wall of the first opening end, and at least one first through hole 1211 connected to the gap 14 is provided on the convex edge 121, and the end of the first through hole 1211 is the aforementioned second air vent 112; the gas processing device can also include a movable part 5, which is movably arranged on the first shell 11, and the movable part 5 is used to move between a first position and a second position relative to the first shell 11, and at least one second through hole 51 is provided on the movable part 5; in the first position, the first through hole 1211 and the second through hole 51 are opposite and connected, so that the second air vent 112 is opened; in the second position, the first through hole 1211 and the second through hole 51 are staggered, so that the second air vent 112 is closed.

[0099] In the above embodiment, the first through hole 1211 on the convex edge 121 is connected to the second air vent 112. Therefore, when the second air vent 112 needs to be opened, the movable part 5 can be placed in the first position, so that the first through hole 1211 and the second through hole 51 are relative and connected, so that the second air vent 112 is opened, that is, the second air vent 112 is connected to the outside through the second through hole 51; when the second air vent 112 needs to be closed, the movable part 5 can be placed in the second position, so that the first through hole 1211 and the second through hole 51 are misaligned, so that the second air vent 112 is closed, that is, the first through hole 1211 is blocked by the movable part 5, so that the second air vent 112 is closed, and the operation is convenient.

[0100] For further convenience of use, in some embodiments, the movable member 5 is rotatably disposed on the first housing 11, and the movable member 5 is used to rotate relative to the first housing 11 to switch between the first position and the second position. When the second vent 112 needs to be opened or closed, it is only necessary to rotate the movable member 5 to switch the state between the first through hole 1211 and the second through hole 51, thereby realizing the opening or closing of the second vent 112, and the operation is more convenient and quick.

[0101] In some embodiments, see Figure 2 , Figure 6 and Figure 7 The gas processing device may further include a connecting member 6, which is connected to the upper shell 13 and is also detachably connected to the first shell 11. The connecting member 6 is used to limit the movable member 5 to the first position or the second position.

[0102] The movable member 5 is movably connected to the connecting member 6, and the movable member 5 is movably connected to the first shell 11 through the connecting member 6. That is, if the connecting member 6 and the upper shell 13 are removed from the first shell 11, the movable member 5 is removed synchronously along with the connecting member 6 and the upper shell 13. In other words, there may be no direct connection between the movable member 5 and the first shell 11, and the movable member 5 may be fixed to the first shell 11 by the connecting member 6.

[0103] In some embodiments, see Figure 4 , Figure 6 and Figure 7, a long strip-shaped limiting through hole 61 can be opened on the connecting member 6, and the limiting through hole 61 extends along the moving direction of the movable member 5; the movable member 5 is movably connected to the connecting member 6, and the movable member 5 is connected to the first shell 11 through the connecting member 6; a limiting protrusion 52 is provided on the movable member 5, and the limiting protrusion 52 is inserted into the limiting through hole 61, and the limiting protrusion 52 is used to move along the extending direction of the limiting protrusion 52 to drive the movable member 5 to move relative to the first shell 11; when the limiting protrusion 52 moves to one end of the limiting through hole 61, the movable member 5 is in the first position, and when the limiting protrusion 52 moves to the other end of the limiting through hole 61, the movable member 5 is in the second position.

[0104] According to the above embodiment, when it is necessary to open the second air vent 112, the limiting protrusion 52 can be moved to one end of the limiting through hole 61. At this time, the movable part 5 can be in the first position, the first through hole 1211 and the second through hole 51 are connected, and the second air vent 112 can be opened; when it is necessary to close the second air vent 112, the limiting protrusion 52 can be moved in the opposite direction to the limiting protrusion 52 to the other end of the limiting through hole 61. At this time, the movable part 5 can be in the second position, the first through hole 1211 and the second through hole 51 are misaligned, the second air vent 112 is closed, and the operation is more convenient.

[0105] Of course, see Figure 6 The connecting member 6 may further be provided with a third through hole 62 communicating with the first through hole 1211 , so that the second vent 112 may be communicated with the outside through the third through hole 62 .

[0106] In some embodiments, see Figure 3 , Figure 6 and Fig.13 , the connecting member 6 is connected to the upper shell 13, and is also detachably connected to the first shell 11, so that the upper shell 13 and the lower shell are detachably connected through the connecting member 6, and the connecting member 6 is used to open or cover the first opening end and the third opening end to achieve the installation and removal of the gas treatment component 2 in the second shell 12. Specifically, when the connecting member 6 is detached from the first shell 11, the first opening end of the first shell 11 and the third opening end of the second shell 12 are opened, and the gas treatment component 2 can be taken out from the second shell 12 at this time to repair or replace the gas treatment component 2; after the gas treatment component 2 is installed in the second shell 12, the connecting member 6 can be connected to the first shell 11 to cover the first opening end and the third opening end to achieve the installation of the gas treatment component 2.

[0107] There are many ways to detachably connect the connector 6 and the first housing 11. For ease of operation, in some embodiments, see Figure 3 , Figure 6 and Fig.13A plurality of card slots 115 may be provided on the inner wall of the first shell 11, and the plurality of card slots 115 are arranged at intervals along the circumference of the first shell 11. A plurality of card blocks 63 are provided on the outer wall of the connecting member 6, and the plurality of card blocks 63 are arranged at intervals along the circumference of the connecting member 6. The card blocks 63 can be plugged in and out of the corresponding card slots 115. Specifically, the shape of the slot can be L-shaped, and the slot includes a first section and a second section that are connected. The first section extends along the axial direction of the first shell 11, and the second section extends along the circumferential direction of the first shell 11. When assembling the connecting member 6 and the first shell 11, the connecting member 6 can be moved first to insert the block 63 into the second section through the first section, and then when the connecting member 6 is screwed along the first direction, the block 63 can be connected to the second section, thereby realizing the connection and fixation between the connecting member 6 and the first shell 11. When the connecting member 6 is screwed along the second direction opposite to the first direction, the block 63 can be moved out of the first section, and then the connecting member 6 can be lifted up to separate the block 63 from the first section, thereby realizing the disassembly and separation of the connecting member 6 from the first shell 11.

[0108] That is to say, there may be no direct connection between the movable member 5 and the first shell 11 , and the movable member 5 may be fixed on the first shell 11 by means of the connecting member 6 .

[0109] In some embodiments, see Figure 2 , Figure 3 and Fig.11 The shell 1 may also include an upper shell 13, which is connected to the connecting member 6, and a fourth through hole 132 is provided on the upper shell 13; a third air vent 131 is provided in the upper shell 13; a gas driving member 3 is arranged in the upper shell 13, and the gas driving member 3 includes an intake end and an exhaust end, the intake end is opposite to and connected to the fourth through hole 132, and the exhaust end is opposite to and connected to the third air vent 131; the gas processing member 2 also includes an outlet end 22, which is opposite to and connected to the fourth through hole 132.

[0110] According to the above embodiment, when the gas driving component 3 is started, its suction end can directly suck the gas discharged from the gas outlet end 22 of the gas processing component 2 to its exhaust end through the fourth through hole 132, and finally discharge it from the third vent 131 to achieve gas processing.

[0111] In addition, since the upper shell 13 is connected to the connecting member 6, when the gas processing component 2 needs to be maintained, the upper shell 13 can be screwed to allow the upper shell 13 to drive the connecting member 6 to rotate relative to the first shell 11, thereby disassembling and separating the connecting member 6 from the first shell 11.

[0112] It can be understood that the fourth through hole 132 can penetrate the connecting member 6 and the movable member 5 so that the gas outlet end 22 of the gas processing member 2 and the gas intake end of the gas driving member 3 can be communicated.

[0113] In some embodiments, see Figure 2 The upper shell 13 may include a first end 133 corresponding to the suction end and a second end 134 corresponding to the exhaust end, and the cross-sectional area of ​​at least the first end 133 of the first end 133 and the second end 134 gradually increases from the first end 133 to the second end 134. That is, the overall shape of the first end 133 may be trumpet-shaped, and the trumpet-shaped structure may reduce the gas flow resistance, thereby being more conducive to the gas driving member 3 sucking gas to discharge the processed gas.

[0114] In some embodiments, the inner wall surface of the first end 133 is an arc surface that protrudes toward the inside of the first end 133, thereby reducing the resistance of the inner wall surface of the first end 133 to the gas flow and being more conducive to the gas flow.

[0115] In some embodiments, the gas processing device may further include a movable part, which is movably arranged on the shell 1, and the movable part 5 is used to move between a first position and a second position relative to the shell 1, and at least one second through hole is provided on the movable part; in the first position, the second air vent 112 and the second through hole are relative to and connected to each other, so that the second air vent 112 is open; in the second position, the second through hole and the second air vent 112 are staggered, so that the second air vent 112 is closed.

[0116] When it is necessary to open the second vent 112, the movable part can be moved to the first position, at which time the second vent 112 is relative to and connected to the second through hole, and the second vent 112 can be opened. When it is necessary to close the second vent 112, the movable part can be moved to the second position, at which time the second through hole and the second vent 112 are staggered, and the second vent 112 is blocked and closed, and the operation is convenient and quick.

[0117] The embodiment of the utility model also provides an additive molding device, characterized in that it includes: an additive molding device, an air pipe and the aforementioned gas processing device, the air pipe is detachably connected to the additive molding device and the gas processing device respectively, and the first vent 111 is used to communicate with the air pipe.
