Description

Technical Field

[0001] The invention belongs to the technical field of cultural relics protection, and more specifically, particularly relates to a cultural relics collecting device with nitrogen protection function. Background Art

[0002] NFC (Near Field Communication) is a short-range wireless communication technology that allows devices to exchange data within a few centimeters. Its background technology can be traced back to the development of RFID (Radio Frequency Identification) technology. NFC usually operates at a frequency of 13.56MHz, which enables fast pairing and data transmission between devices. The key features of NFC technology include low power consumption, ease of use, and high security. It supports a variety of application scenarios, such as mobile payments, smart tags, data exchange, electronic ticketing, etc. NFC devices can be divided into two types: active and passive. Active devices can send and receive signals, while passive devices are powered and transmit data through signals sent by active devices.

[0003] The protection and research of cultural relics involves sampling of cultural relics. At present, in the sampling of cultural relics, the extracted cultural relic samples are generally stored in plastic ziplock bags, and then the sample information is registered on label paper, which is then affixed to the sample bag. This method of preserving and registering cultural relic samples has great defects. In terms of sample preservation, when sealing cultural relic samples with ziplock bags, although the air in the bag is beneficial to prevent the cultural relic samples from being squeezed and collided, it is easy to cause the cultural relic samples to oxidize; although exhausting the air in the bag is beneficial to prevent the samples from being oxidized, it also loses the buffering effect of the gas against squeezing and collision. In terms of information registration, the space on the label paper is limited and it is difficult to fill in detailed registration information, and the label paper is easy to fall off when it is attached to the surface of the ziplock bag, resulting in information loss.

[0004] Traditional cultural relics protection bags usually only provide simple wrapping and isolation functions, and have limited effect in protecting cultural relics from extrusion and collision, and cannot effectively buffer external pressure shocks.

[0005] In terms of preventing cultural relics from oxidizing, the lack of effective gas replacement and control methods makes it difficult to reduce the oxygen content in the storage environment of cultural relics, thus failing to provide good antioxidant protection for the cultural relics.

[0006] As for the sealing and operation convenience of cultural relics protection bags, the existing designs are often not ideal. The sealing method is complicated, the protection performance is unstable, and when it is necessary to remove or replace the internal protection parts, the operation is cumbersome and difficult.

[0007] During the nitrogen filling process, the existing methods may have problems such as slow nitrogen filling speed and difficult operation, and are unable to quickly and effectively create a suitable nitrogen environment for cultural relics.

[0008] In addition, cultural relics protection bags also have limitations in production, manufacturing and maintenance. Existing products are usually of integrated design, and each component cannot be produced and tested independently, making it difficult to ensure production efficiency and quality. Moreover, once a part is damaged or its performance deteriorates, the entire protection bag often needs to be replaced, increasing the cost of use.

[0009] At the same time, the existing cultural relics protection bags have weak self-repair and multi-layer protection capabilities when dealing with external impacts and damage. Once the protective bag is scratched or damaged, it cannot be effectively self-repaired and provide additional protection in a timely manner, increasing the risk of damage to cultural relics.

[0010] In terms of exhaust design, the existing exhaust structure is simple and cannot effectively exhaust oxygen. It is also difficult to prevent the backflow of external air, which affects the stability of the gas environment in the cultural relics protection bag. Summary of the invention

[0013] Preferably, positioning holes are provided through the upper and lower sides of the middle part of the partition frame, and two first magnetic blocks are fixedly installed on the upper and lower sides of the partition frame located on both sides of the positioning holes. The partition frame is located at one-third of the top from the bottom of the cultural relics protection bag, an NFC chip is fixedly installed in the middle of the front surface of the cultural relics protection bag, the front side surfaces of the cultural relics protection bag near the top and the bottom are fixedly installed with second Velcro, and the rear side surfaces of the cultural relics protection bag near the top and the bottom are fixedly installed with first Velcro, a supporting bag is fixedly installed on the inner wall of the cultural relics protection bag located below the partition frame, a groove is provided above the supporting bag, and an annular metal clip is installed inside the supporting bag through the groove, and when the nitrogen filling bag is located inside the cultural relics protection bag, the annular metal clip is sleeved on the outer ring of the nitrogen filling bag, and the annular metal clip is used to squeeze the nitrogen filling bag so that the nitrogen inside the nitrogen filling bag is discharged.

[0014] Preferably, the cultural relics protection bag is composed of a plurality of layers, including: a first protective layer, a second protective layer and a third protective layer, the cultural relics protection bag is the outermost layer, and the third protective layer is the innermost layer, and air chambers are formed between the cultural relics protection bag, the first protective layer, the second protective layer and the third protective layer, and the air chambers are used for separation to improve the protective effect of the multiple layers inside the cultural relics protection bag, the surfaces of the first protective layer and the second protective layer are covered with a sealant layer, and each sealant layer faces the cultural relics protection bag, and each sealant layer has strong viscosity. When the cultural relics protection bag or the sealant layer is broken, each sealant layer will adhere to the previous layer to fill the broken holes, and two second magnetic blocks are fixedly embedded at the bottom of the cultural relics sample bag, and two third magnetic blocks are fixedly embedded at the top of the nitrogen-filled bag.

[0015] Preferably, when the cultural relic sample bag and the nitrogen-filled bag are both installed inside the cultural relic protection bag, the two third magnetic blocks at the top of the nitrogen-filled bag are magnetically attracted to the two first magnetic blocks at the bottom of the partition frame, and the two second magnetic blocks at the bottom of the cultural relic sample bag are magnetically attracted to the two first magnetic blocks at the top of the partition frame, each of the exhaust bins is provided with a first air inlet groove, a first lower U-groove, a second lower U-groove, an upper U-groove and a Z-shaped groove, and the first air inlet groove, the first lower U-groove, the second lower U-groove, the upper U-groove and the Z-shaped groove are opened in sequence from the inner wall to the outer wall of the cultural relic sample bag, a third one-way valve is fixedly installed at the connection between each of the first air inlet groove and the first lower U-groove, air can only be discharged outward from the third one-way valve, and cannot flow back from the first lower U-groove to the third one-way valve, the end of each of the first lower U-groove is connected to the initial end of the second lower U-groove, the end of each of the second lower U-groove is connected to the initial end of the upper U-groove, the end of each of the upper U-groove is connected to the initial end of the Z-shaped groove, and each of the Z-shaped grooves is connected to the outside of the cultural relic sample bag.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the nitrogen-filled bag is squeezed to inject nitrogen into the cultural relic sample bag through the second one-way valve and the first one-way valve, and the original air in the cultural relic sample bag is discharged through the exhaust chamber. At this time, the nitrogen content inside the cultural relic sample bag is relatively high, and the filling effect of the nitrogen can make the cultural relic sample bag bulge, which is beneficial to prevent the cultural relic samples from being squeezed and collided. At the same time, the nitrogen also plays a role in reducing the oxygen content in the cultural relic sample bag, which is beneficial to the anti-oxidation of the cultural relic samples. The front side of the cultural relic protection bag is also integrated with an NFC chip. When registering information on cultural relic sampling, a mobile phone or other device can be used to approach the NFC chip of the cultural relic protection bag. After the mobile phone senses the NFC chip, the electronic registration interface of the cultural relic sample information can be opened on the mobile phone to realize the electronic registration of the cultural relic sample information, thereby solving the problem that the physical label paper is easy to fall off and lose, and the problem of limited registration information.

[0017] In the present invention, the nitrogen-filled bag is inserted into the cultural relic protection bag from bottom to top, the second one-way valve on the top of the nitrogen-filled bag is inserted into the first one-way valve, and at the same time, two third magnetic blocks on the top of the nitrogen-filled bag are magnetically attracted to the first magnetic block at the bottom of the partition frame, and the partition frame is fixed inside the cultural relic protection bag, so that the cultural relic sample bag and the nitrogen-filled bag can be easily installed, and the accuracy of the installation of the cultural relic sample bag and the nitrogen-filled bag is improved, and at the same time, it can be prevented that the nitrogen-filled bag leaks nitrogen due to deflection when discharging nitrogen, and at the same time, a plurality of first magnetic blocks, third magnetic blocks and second magnetic blocks are used for magnetic attraction, so that it can be ensured that the cultural relic sample bag and the nitrogen-filled bag will not fall off after installation, thereby improving the safety of installation.

[0018] In the present invention, the first Velcro on the top and bottom of the cultural relic protection bag are both adhered to the second Velcro on the reverse side, and at this time, the first Velcro and the second Velcro can seal the top and bottom of the cultural relic protection bag, the operation is simple, and the protection performance is good, and the nitrogen filling bag and the cultural relic sample bag can be protected. When taking the nitrogen filling bag and the cultural relic sample bag, an annular metal clip is installed at the bottom of the nitrogen filling bag, and a first pull ring is installed at the top of the cultural relic sample bag, so the user can directly pull the second pull ring and the first pull ring to remove the nitrogen filling bag and the cultural relic sample bag, which greatly improves the convenience of disassembly.

[0019] In the present invention, when it is necessary to squeeze the nitrogen in the nitrogen filling bag into the cultural relic sample bag, the user squeezes the annular metal clip with force, and when the middle part of the annular metal clip is subjected to force, both sides of the annular metal clip are driven to deform together. At this time, the deformation of the annular metal clip can increase the squeezing force on the nitrogen filling bag, and the nitrogen in the nitrogen filling bag can be quickly flushed into the cultural relic sample bag, thereby effectively increasing the nitrogen flushing speed and reducing the operation difficulty of different groups of people.

[0020] In the present invention, the nitrogen filling bag and the cultural relic sample bag inside the cultural relic protection bag are both independently designed, so that during the production process, each module can be more conveniently manufactured and quality tested separately, thereby improving production efficiency and product quality. During use, if a module is damaged or needs maintenance, the corresponding module can be replaced separately without replacing the entire cultural relic protection bag, thereby reducing the cost of use. For example, when the nitrogen inside the cultural relic sample bag is insufficient, the user can replace the nitrogen filling bag, and the nitrogen filling bag can repeatedly fill the cultural relic sample bag with nitrogen, thereby extending the service life of the cultural relic protection bag.

[0021] In the present invention, when encountering external force impact, it can play a better protective role. When the cultural relic protection bag is scratched by foreign objects, the air between the cultural relic protection bag and the first protective layer will be quickly discharged. At this time, the first protective layer will be quickly adhered to the inner layer of the cultural relic protection bag under pressure. At this time, the sealant layer on the surface of the first protective layer will adhere and seal with the inner layer of the cultural relic protection bag. At this time, the first protective layer plays a role in repairing the cultural relic protection bag and can play a second-layer protective role. Similarly, when the first protective layer is damaged, the second protective layer can play the same protective role. The cultural relic protection bag adopts a multi-layer design and a self-repairing function, so that the overall protective ability of the cultural relic protection bag can be improved, and the protection of cultural relics is further improved.

[0022] In the present invention, air enters the second lower U groove through the first lower U groove, then the air enters the upper U groove through the second lower U groove, and finally is discharged outward through the Z-shaped groove. The exhaust bin adopts a design in which the first air inlet groove has a large opening and the Z-shaped groove has a small opening. The aperture at one end of the Z-shaped groove is slightly larger, which is conducive to oxygen gathering and outflow. The aperture at one end of the Z-shaped groove becomes smaller, which can appropriately limit the gas flow rate and prevent nitrogen from leaking too quickly. The first air inlet groove, the first lower U groove, the second lower U groove, the upper U groove and the Z-shaped groove in the exhaust bin are generally of a tortuous design. The tortuous design can increase the contact area and residence time between the gas and the channel wall, which is conducive to the gradual discharge of oxygen molecules to the outside through diffusion, and at the same time can prevent the rapid backflow of external air to a certain extent.

At the same time, the nitrogen also plays a role in reducing the oxygen content in the cultural relics sample bag 3, which is beneficial to the anti-oxidation of the cultural relics samples. The front side of the cultural relics protection bag 1 is also integrated with an NFC chip 11. When the cultural relics are sampled and registered, a mobile phone or other device can be used to approach the NFC chip 11 of the cultural relics protection bag 1. After the mobile phone senses the NFC chip 11, the electronic registration interface of the cultural relics sample information can be opened on the mobile phone to realize the electronic registration of the cultural relics sample information. The inner walls on both sides of the opening of the cultural relics sample bag 3 are respectively fixedly installed with sealing grooves 38 and sealing convex strips 39. The left and right side walls of the cultural relics sample bag 3 near the top are fixedly installed with two exhaust bins 4, and the two exhaust bins 4 are used for oxygen discharge.

[0027] Positioning holes 15 are provided on the upper and lower sides of the middle of the partition frame 14, and two first magnetic blocks 16 are fixedly installed on the upper and lower sides of the partition frame 14 on both sides of the positioning holes 15. The partition frame 14 is located at one-third of the top from the bottom of the cultural relics protection bag 1, and an NFC chip 11 is fixedly installed in the middle of the front surface of the cultural relics protection bag 1. The front side surfaces of the cultural relics protection bag 1 near the top and the bottom are fixedly installed with second Velcro 13, and the rear side surfaces of the cultural relics protection bag 1 near the top and the bottom are fixedly installed with first Velcro 12. A supporting bag 18 is fixedly installed on the inner wall of the cultural relics protection bag 1 below the partition frame 14, and a groove 19 is provided above the supporting bag 18. The inner part of the supporting bag 18 is through An annular metal clamp 17 is installed through the groove 19. When the nitrogen-filled bag 34 is located inside the cultural relic protection bag 1, the annular metal clamp 17 is sleeved on the outer ring of the nitrogen-filled bag 34. The annular metal clamp 17 is used to squeeze the nitrogen-filled bag 34 so that the nitrogen inside the nitrogen-filled bag 34 is discharged, so that the cultural relic sample bag 3 and the nitrogen-filled bag 34 can be easily installed, and the accuracy of the installation of the cultural relic sample bag 3 and the nitrogen-filled bag 34 is improved. At the same time, it can prevent the nitrogen-filled bag 34 from leaking nitrogen due to deflection when discharging nitrogen. At the same time, multiple first magnetic blocks 16, third magnetic blocks 35 and second magnetic blocks 32 are used for magnetic attraction, which can ensure that the cultural relic sample bag 3 and the nitrogen-filled bag 34 will not fall off after installation, thereby improving the safety of installation.

[0028] The cultural relics protection bag 1 is composed of multiple layers, including: a first protective layer 2, a second protective layer 22 and a third protective layer 23. The cultural relics protection bag 1 is the outermost layer, and the third protective layer 23 is the innermost layer. An air filling chamber 24 is formed between the cultural relics protection bag 1, the first protective layer 2, the second protective layer 22 and the third protective layer 23. The air filling chamber 24 is used for separation to improve the protective effect of the multiple layers inside the cultural relics protection bag 1. The surfaces of the first protective layer 2 and the second protective layer 22 are covered with a sealing layer 21, and each sealing layer 21 faces the cultural relics protection bag 1. Each sealing layer 21 has strong viscosity. When the cultural relics protection bag 1 or the sealing layer 21 is broken, each sealing layer 21 The adhesive layer 21 will adhere to the previous layer to fill the broken holes. Two second magnetic blocks 32 are fixedly embedded in the bottom of the cultural relic sample bag 3, and two third magnetic blocks 35 are fixedly embedded in the top of the nitrogen bag 34. At this time, the sealing adhesive layer 21 on the surface of the first protective layer 2 will adhere and seal with the inner layer of the cultural relic protection bag 1. At this time, the first protective layer 2 plays a role in repairing the cultural relic protection bag 1 and can play a second layer of protection. Similarly, when the first protective layer 2 is damaged, the second protective layer 22 can play the same protective role. The cultural relic protection bag 1 adopts a multi-layer design and a self-repairing function, so as to improve the overall protection ability of the cultural relic protection bag 1 and further improve the protection of cultural relics.

[0029] When the cultural relic sample bag 3 and the nitrogen-filled bag 34 are both installed inside the cultural relic protection bag 1, the two third magnetic blocks 35 at the top of the nitrogen-filled bag 34 are magnetically attracted to the two first magnetic blocks 16 at the bottom of the partition frame 14, and the two second magnetic blocks 32 at the bottom of the cultural relic sample bag 3 are magnetically attracted to the two first magnetic blocks 16 at the top of the partition frame 14, and each exhaust chamber 4 is provided with a first air inlet groove 41, a first lower U groove 43, a second lower U groove 44, an upper U groove 45 and a Z-shaped groove 46 inside, and the first air inlet groove 41, the first lower U groove 43, the second lower U groove 44, the upper U groove 45 and the Z-shaped groove 46 are opened in sequence from the inner wall to the outer wall of the cultural relic sample bag 3, and a third one-way valve 42 is fixedly installed at the connection between each first air inlet groove 41 and the first lower U groove 43, so that air can only be discharged outward from the third one-way valve 42, and cannot be discharged outward from the first lower The U-groove 43 flows back to the third one-way valve 42, and the end of each first lower U-groove 43 is connected to the initial end of the second lower U-groove 44, and the end of each second lower U-groove 44 is connected to the initial end of the upper U-groove 45, and the end of each upper U-groove 45 is connected to the initial end of the Z-shaped groove 46. The air continues to move forward, and the air enters the second lower U-groove 44 through the first lower U-groove 43, and then the air enters the upper U-groove 45 through the second lower U-groove 44, and finally is discharged outward through the Z-shaped groove 46. The exhaust chamber 4 adopts the design of a large opening of the first air inlet groove 41 and a small opening of the Z-shaped groove 46. The aperture of one end of the Z-shaped groove 46 is slightly larger, which is conducive to oxygen gathering and outflow, and the aperture of one end of the Z-shaped groove 46 becomes smaller, which can appropriately limit the gas flow rate to prevent nitrogen from leaking too quickly. Each Z-shaped groove 46 is connected to the outside of the cultural relic sample bag 3.

[0030] Working principle: In the first step, when collecting cultural relics, the user puts the cultural relics into the cultural relic sample bag 3, and then squeezes and seals the opening of the cultural relic sample bag 3 through the sealing groove 38 and the sealing convex strip 39, and then puts the cultural relic sample bag 3 into the cultural relic protection bag 1, and then sticks the first Velcro 12 and the second Velcro 13 on the top of the cultural relic protection bag 1, and then puts the nitrogen-filled bag 34 into the cultural relic protection bag 1. At this time, the second one-way valve 36 on the top of the nitrogen-filled bag 34 is inserted into the first one-way valve 31 at the bottom of the cultural relic sample bag 3, and then presses the cultural relic protection bag 1, and the nitrogen-filled bag 34 is squeezed to inject nitrogen into the cultural relic sample bag 3 through the second one-way valve 36 and the first one-way valve 31. The original air in the cultural relic sample bag 3 is discharged through the exhaust chamber 4. At this time, the nitrogen content inside the cultural relic sample bag 3 is relatively high. The filling effect of nitrogen can make the cultural relic sample bag 3 swell, which is beneficial to prevent the cultural relic samples from being squeezed and collided. At the same time, nitrogen also plays a role in reducing the oxygen content in the cultural relic sample bag 3, which is beneficial to prevent the cultural relic samples from being oxidized. The front side of the cultural relic protection bag 1 is also integrated with an NFC chip 11. When registering the cultural relic sampling information, a mobile phone or other device can be used to approach the NFC chip 11 of the cultural relic protection bag 1. After the mobile phone senses the NFC chip 11, the electronic registration interface of the cultural relic sample information can be opened on the mobile phone to realize the electronic registration of the cultural relic sample information.

[0031] In the second step, when installing the cultural relic sample bag 3, the cultural relic sample bag 3 is inserted into the cultural relic protection bag 1 from top to bottom, and the cultural relic sample bag 3 moves downward to the partition frame 14 and stops. At this time, the first one-way valve 31 at the bottom of the cultural relic sample bag 3 is inserted into the positioning hole 15 opened in the partition frame 14, and at the same time, the two second magnetic blocks 32 at the bottom of the cultural relic sample bag 3 are magnetically attracted to the two first magnetic blocks 16 at the top of the partition frame 14, and then the nitrogen-filled bag 34 is inserted into the cultural relic protection bag 1 from bottom to top, and the second one-way valve 36 at the top of the nitrogen-filled bag 34 is inserted into the first one-way valve 31. At the same time, the top of the nitrogen-filled bag 34 The two third magnetic blocks 35 are magnetically attracted to the first magnetic block 16 at the bottom of the partition frame 14. By fixing the partition frame 14 inside the cultural relic protection bag 1, the cultural relic sample bag 3 and the nitrogen-filled bag 34 can be easily installed, thereby improving the accuracy of the installation of the cultural relic sample bag 3 and the nitrogen-filled bag 34, and preventing the nitrogen-filled bag 34 from leaking due to deflection when discharging nitrogen. At the same time, the plurality of first magnetic blocks 16, the third magnetic block 35 and the second magnetic block 32 are used for magnetic attraction, thereby ensuring that the cultural relic sample bag 3 and the nitrogen-filled bag 34 will not fall off after installation, thereby improving the safety of installation; After the cultural relic sample bag 3 and the nitrogen-filled bag 34 are installed, the user sticks the first Velcro 12 on the top and bottom of the cultural relic protection bag 1 to the second Velcro 13 on the back. At this time, the first Velcro 12 and the second Velcro 13 can seal the top and bottom of the cultural relic protection bag 1. The operation is simple and the protection performance is good. It can protect the nitrogen-filled bag 34 and the cultural relic sample bag 3. When taking the nitrogen-filled bag 34 and the cultural relic sample bag 3, an annular metal clip 17 is installed at the bottom of the nitrogen-filled bag 34, and a first pull ring 33 is installed at the top of the cultural relic sample bag 3. Therefore, the user can directly pull the second pull ring 37 and the first pull ring 33 to remove the nitrogen-filled bag 34 and the cultural relic sample bag 3, which greatly improves the convenience of disassembly.

[0032] In the third step, when it is necessary to squeeze the nitrogen in the nitrogen filling bag 34 into the cultural relic sample bag 3, the user squeezes the annular metal clip 17 with force. When the middle of the annular metal clip 17 is stressed, the two sides will be deformed together. At this time, the deformation of the annular metal clip 17 can increase the squeezing force on the nitrogen filling bag 34, and the nitrogen in the nitrogen filling bag 34 can be quickly filled into the cultural relic sample bag 3, effectively increasing the nitrogen filling speed and reducing the operation difficulty of different groups of people; The nitrogen filling bag 34 and the cultural relic sample bag 3 inside the cultural relic protection bag 1 are both independently designed, so that during the production process, each module can be more conveniently manufactured and quality tested separately, thereby improving production efficiency and product quality. During use, if a module is damaged or needs maintenance, the corresponding module can be replaced separately without replacing the entire cultural relic protection bag 1, thereby reducing the use cost. For example, when the nitrogen inside the cultural relic sample bag 3 is insufficient, the user can replace the nitrogen filling bag 34, and the nitrogen filling bag 34 can repeatedly fill the cultural relic sample bag 3 with nitrogen, thereby extending the service life of the cultural relic protection bag 1; The cultural relic protection bag 1 adopts a multi-layer design, and the cultural relic protection bag 1, the first protective layer 2, the second protective layer 22 and the third protective layer 23 are separated by an air chamber 24. Therefore, the overall structure of the cultural relic protection bag 1 has good impact resistance and can play a good protective role when encountering external force impact. When the cultural relic protection bag 1 is scratched by a foreign object, the air between the cultural relic protection bag 1 and the first protective layer 2 will be quickly discharged. At this time, the first protective layer 2 will be pressed and will quickly adhere to the inner layer of the cultural relic protection bag 1. At this time, the sealant layer 21 on the surface of the first protective layer 2 will adhere and seal with the inner layer of the cultural relic protection bag 1. At this time, the first protective layer 2 plays a role in repairing the cultural relic protection bag 1 and can play a second-layer protection role. Similarly, when the first protective layer 2 is damaged, the second protective layer 22 can play the same protective role. The cultural relic protection bag 1 adopts a multi-layer design and a self-repairing function, thereby improving the overall protection ability of the cultural relic protection bag 1 and further improving the protection of cultural relics. When the nitrogen in the nitrogen filling bag 34 is filled into the cultural relic sample bag 3, the nitrogen quickly enters the cultural relic sample bag 3, and the original air in the cultural relic sample bag 3 quickly enters the first air inlet groove 41, and the air passes through the third one-way valve 42 and enters the first lower U groove 43. The air entering the first lower U groove 43 can no longer return to the cultural relic sample bag 3 through the third one-way valve 42, and the air continues to move forward, and the air passes through the first lower U groove 43 and enters the second lower U groove 44, and then the air passes through the second lower U groove 44 and enters the upper U groove 45, and finally is discharged outward through the Z-shaped groove 46, and the exhaust chamber 4 is used. The first air inlet groove 41 is designed with a large opening and the Z-shaped groove 46 is designed with a small opening. The aperture of one end of the Z-shaped groove 46 is slightly larger, which is conducive to the gathering and outflow of oxygen. The aperture of one end of the Z-shaped groove 46 becomes smaller, which can appropriately limit the gas flow rate and prevent nitrogen from leaking too quickly. The first air inlet groove 41, the first lower U groove 43, the second lower U groove 44, the upper U groove 45 and the Z-shaped groove 46 in the exhaust chamber 4 are generally of a tortuous design. The tortuous design can increase the contact area and residence time between the gas and the channel wall, which is conducive to the gradual discharge of oxygen molecules to the outside through diffusion, and at the same time can prevent the rapid backflow of external air to a certain extent.
