Description

Technical Field

[0001] This invention relates to the field of electrical appliances, and more specifically to a refrigeration device. Background Technology

[0002] When preserving food such as vegetables and fruits, it's not only about lowering the temperature of the food, but also about adjusting the oxygen content within the storage space. Existing refrigeration equipment includes containers with adjustable oxygen levels for food storage, but each container can only be set to either a high-oxygen or low-oxygen state, making it impossible to flexibly switch between them according to user needs. Summary of the Invention

[0003] The purpose of this invention is to provide a refrigeration device that can switch between a low-oxygen state and a high-oxygen state inside a container.

[0004] To achieve the above objectives, the present invention provides a refrigeration device, including a container and an oxygen control module located outside the container. The container has a low-oxygen through hole and a high-oxygen through hole communicating with its interior and exterior. The oxygen control module has a low-oxygen interface corresponding to the low-oxygen through hole and a high-oxygen interface corresponding to the high-oxygen through hole.

[0005] The refrigeration equipment also includes a converter disposed between the container and the oxygen control module. The converter has a first state and a second state. When the converter is in the first state, the low oxygen interface is connected to the low oxygen through hole and the high oxygen interface is connected to the outside of the container. When the converter is in the second state, the high oxygen interface is connected to the high oxygen through hole and the low oxygen interface is connected to the outside of the container.

[0006] As a further improvement of the present invention, the converter includes a valve seat movably disposed relative to the container along a first direction, the valve seat including a main body and a plurality of adapter ports arranged along the first direction on the main body;

[0007] The adapter includes a first adapter and a second adapter. The valve seat is movable to a first position and a second position. When the converter is in the first state, the valve seat is in the first position. When the converter is in the second state, the valve seat is in the second position. When the valve seat is in the first position, the first adapter connects to the low-oxygen interface and the low-oxygen through hole. When the valve seat is in the second position, the second adapter connects to the high-oxygen interface and the high-oxygen through hole.

[0008] As a further improvement of the present invention, the adapter further includes a third adapter and a fourth adapter. When the valve seat is in the first position, one end of the third adapter is connected to the high oxygen interface and the other end is connected to the outside of the container. When the valve seat is in the second position, one end of the fourth adapter is connected to the low oxygen interface and the other end is connected to the outside of the container.

[0009] As a further improvement of the present invention, the main body includes a first side, a second side and a third side located on different sides thereon, the two ends of the first adapter and the second adapter respectively penetrate through the first side and the second side, and the two ends of the third adapter and the fourth adapter respectively penetrate through the first side and the third side.

[0010] As a further improvement of the present invention, the converter further includes a fixing plate fixedly disposed relative to the container, the valve seat being slidably connected to the fixing plate along a first direction, the fixing plate being provided with a first mark and a second mark arranged along the first direction, the valve seat being in a first position covering the second mark to expose the first mark, and the converter being in a second position covering the first mark to expose the second mark.

[0011] As a further improvement of the present invention, a sliding limiting structure is provided between the valve seat and the fixed plate for limiting the movable range of the valve seat relative to the fixed plate from a first position to a second position.

[0012] As a further improvement of the present invention, the converter includes a base and a valve core rotatably disposed in the base. The base includes a first opening communicating with the low oxygen interface, a second opening communicating with the low oxygen through hole, a third opening communicating with the high oxygen interface, a fourth opening communicating with the high oxygen through hole, and a fifth and a sixth opening communicating with the outside of the container. The valve core can be rotated to a third position and a fourth position. When the converter is in the first state, the valve core is in the third position, and when the converter is in the second state, the valve core is in the fourth position.

[0013] When the valve core is in the third position, the first opening and the second opening are connected, and the third opening and the sixth opening are connected. When the valve core is in the fourth position, the third opening and the fourth opening are connected, and the first opening and the fifth opening are connected.

[0014] As a further improvement of the present invention, the valve core is provided with a first three-way hole and a second three-way hole arranged along its axial direction. The first three-way hole includes a first port, a second port and a third port located on the outer peripheral surface of the valve core, and the second three-way hole includes a fourth port, a fifth port and a sixth port located on the outer peripheral surface of the valve core.

[0015] When the valve core is in the third position, the first port corresponds to the first opening, the second port corresponds to the second opening, the fifth port corresponds to the sixth opening, and the sixth port corresponds to the third opening. When the valve core is in the fourth position, the first port corresponds to the fifth opening, the third port corresponds to the first opening, the fourth port corresponds to the fourth opening, and the fifth port corresponds to the third opening.

[0016] As a further improvement of the present invention, the valve core is provided with a third mark and a fourth mark arranged in its circumferential direction, and the converter also includes an indicator mark located on one side of the valve core in the radial direction. When the valve core is in the third position, the indicator mark points to the third mark, and when the valve core is in the fourth position, the indicator mark points to the fourth mark.

[0017] As a further improvement of the present invention, the valve core includes an extension that extends out of the seat body, and the outer periphery of the extension is formed with anti-slip texture.

[0018] Beneficial effects:

[0019] In the refrigeration equipment provided by the present invention, the oxygen content in the air inside the container can be changed by controlling whether the converter is in the first state or the second state, so that the inside of the container can be changed into a high oxygen area or a low oxygen area according to the customer's needs.

[0047] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0048] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0049] This invention provides a refrigeration device, such as... Figure 1-18As shown, the refrigeration equipment includes a container 10 and an oxygen control module 20 located outside the container 10.

[0050] Container 10 is used to store food such as vegetables and fruits. It can be understood as a box-shaped object placed in a compartment of a refrigeration device (such as a cold storage compartment), or a structure that isolates storage space in a compartment, or an inner liner structure that forms an entire compartment.

[0051] The oxygen control module 20 includes a low oxygen interface 21 and a high oxygen interface 22. External air can enter the oxygen control module 20 through the low oxygen interface 21. After the external air enters the oxygen control module 20, the oxygen control module 20 will discharge the oxygen in the external air through the high oxygen interface 22, and low oxygen gas will be formed inside the oxygen control module 20.

[0052] In this article, low-oxygen gas is gas with an oxygen content lower than that of the atmosphere, and high-oxygen gas is gas with an oxygen content higher than that of the atmosphere.

[0053] The container 10 has a low-oxygen through-hole 11 and a high-oxygen through-hole 12 connecting its interior and exterior. The low-oxygen interface 21 and the low-oxygen through-hole 11 are correspondingly arranged, and the high-oxygen interface 22 and the high-oxygen through-hole 12 are correspondingly arranged. The refrigeration equipment also includes a converter 30 disposed between the container 10 and the oxygen control module 20. The converter 30 is used to control whether the low-oxygen interface 21 and the low-oxygen through-hole 11 are connected, and whether the high-oxygen interface 22 and the high-oxygen through-hole 12 are connected.

[0054] The converter 30 includes a first state and a second state. When the converter 30 is in the first state, the low-oxygen interface 21 connects to the low-oxygen through-hole 11, which in turn connects to the interior of the container 10, and the high-oxygen connector connects to the exterior of the container 10. When the oxygen control module 20 is working, air from inside the container 10 enters it. The oxygen control module 20 can discharge the oxygen from the incoming air to the exterior of the container 10 through the high-oxygen connector, thus creating low-oxygen gas inside the oxygen control module 20. Because the oxygen control module 20 and the interior of the container 10 are connected, the oxygen content inside the container 10 decreases due to natural airflow, thus creating a low-oxygen region inside the container 10. In this text, the exterior of the container 10 refers to the atmosphere.

[0055] When the converter 30 is in the second state, the high oxygen interface 22 is connected to the high oxygen through hole 12, which in turn connects to the inside of the container 10, and the low oxygen interface 21 is connected to the outside of the container 10. Air from the outside of the container 10, i.e., the atmosphere, can enter the oxygen control module 20 through the low oxygen interface 21. The oxygen control module 20 will discharge the oxygen in the air that enters it into the container 10 through the high oxygen interface 22 and the high oxygen through hole 12, thereby increasing the oxygen content in the air inside the container 10 and making the inside of the container 10 a high oxygen area.

[0056] Understandably, container 10 is not completely sealed. When oxygen enters container 10 through high oxygen vent 12, the air in container 10 will leak out through the gaps in container 10.

[0057] The oxygen control module 20 includes a cathode plate, an anode plate, and an electrolyte filling the space between the cathode plate and the anode plate. The oxygen control module comes into contact with air from inside the container 10 through the cathode plate. Oxygen from the air inside the container 10 undergoes a reduction reaction at the cathode plate: O2 + 2H2O + 4e- - →4OH - Correspondingly, an oxidation reaction occurs at the anode plate, generating oxygen, i.e.: 4OH⁻ - →O2 + 2H2O + 4e - The oxygen generated at the anode plate is discharged into the atmosphere. It can be seen that the oxygen control module 20 can transfer the oxygen in the container 10 to the atmosphere, thereby reducing the oxygen concentration in the container 10.

[0058] As can be imagined, to increase the oxygen content in container 10, the cathode plate can be exposed to air from the atmosphere. The oxygen in the air from the atmosphere will undergo a reduction reaction at the cathode plate: O2 + 2H2O + 4e - →4OH - Correspondingly, an oxidation reaction occurs at the anode plate, generating oxygen, i.e.: 4OH⁻ - →O2 + 2H2O + 4e - The oxygen generated at the anode plate is discharged into container 10 to increase the oxygen content in container 10.

[0059] In summary, the refrigeration equipment provided by this invention allows for the alteration of the oxygen content inside the container 10 by controlling whether the converter 30 is in the first or second state. This enables the container 10 to be configured as a high-oxygen or low-oxygen area according to customer needs. Specifically, when the converter 30 is in the first state, the container 10 becomes a low-oxygen area; when the converter 30 is in the second state, the container 10 becomes a high-oxygen area.

[0060] like Figure 1-10 As shown, in a first specific embodiment of the present invention, the converter 30 includes a valve seat 31 movably disposed relative to the container 10 along a first direction. The valve seat 31 includes a main body 311 and a plurality of adapter ports 312 arranged along the first direction on the main body 311.

[0061] It should be noted that in this article, the first direction refers to the location of container 10, oxygen control module 20, and converter 30. Figure 8 The up and down directions in the shown state.

[0062] The adapter 312 includes a first adapter 3121 and a second adapter 3122, and the valve seat 31 can move along a first direction to a first position and a second position. When the converter 30 is in the first state, the valve seat 31 is in the first position. When the converter 30 is in the second state, the valve seat 31 is in the second position. That is, when the valve seat 31 switches between the first position and the second position, the converter 30 will also switch between the first state and the second state.

[0063] Specifically, when valve seat 31 is in the first position (e.g.) Figure 7-8 As shown), the first adapter 3121 connects the low-oxygen interface 21 and the low-oxygen through hole 11, so that the oxygen control module 20 can connect to the inside of the container 10. When the valve seat 31 is in the second position (as shown), Figure 9-10 As shown), the second adapter 3122 connects the high oxygen interface 22 and the high oxygen through hole 12, so that the oxygen discharged from the high oxygen interface 22 of the oxygen control module 20 can enter the interior of the container 10.

[0064] Furthermore, the adapter 312 also includes a third adapter 3123 and a fourth adapter 3124. When the valve seat 31 is in the first position, one end of the third adapter 3123 is connected to the high-oxygen port 22, and the other end is connected to the outside of the container 10. When the valve seat 31 is in the first position, the oxygen control module 20 needs to discharge the oxygen in its internal air through the high-oxygen port 22. With the above configuration, the oxygen discharged from the high-oxygen port 22 will be discharged to the outside of the container 10 after passing through the third adapter 3123.

[0065] When the valve seat 31 is in the second position, one end of the fourth adapter 3124 is connected to the low oxygen port 21, and the other end is connected to the outside of the container 10. When the valve seat 31 is in the second position, external air needs to enter the oxygen control module 20 so that oxygen can be discharged from the high oxygen port 22 of the oxygen control module 20. With the above setting, external air enters the low oxygen port 21 through the fourth adapter 3124 and then enters the oxygen control module 20.

[0066] In other embodiments, the third adapter 3123 and the fourth adapter 3124 may be omitted. When the valve seat 31 is in the first position, there is a gap between it and the high-oxygen interface 22, and the air outlet of the high-oxygen interface 22 is exposed to the atmosphere, thus directly connecting to the atmosphere. Similarly, when the valve seat 31 is in the second position, there is a gap between it and the low-oxygen interface 21, and the air inlet of the low-oxygen interface 21 is exposed to the atmosphere, thus directly connecting to the atmosphere.

[0067] In this embodiment, the main body 311 includes a first side 3125, a second side 3126 and a third side 3127 located on different sides thereon. The two ends of the first adapter 3121 and the second adapter 3122 respectively penetrate through the first side 3125 and the second side 3126. The two ends of the third adapter 3123 and the fourth adapter 3124 respectively penetrate through the first side 3125 and the third side 3127.

[0068] The low-oxygen interface 21 and high-oxygen interface 22 on the oxygen control module 20 are located near the first side 3125, and the low-oxygen through hole 11 and high-oxygen through hole 12 on the container 10 are located near the second side 3126. In this embodiment, the first side 3125 and the second side 3126 are two opposite sides on the main body 311, and the third side 3127 connects the first side 3125 and the second side 3126. The container 10 and the oxygen control module 20 are located on opposite sides of the converter 30, respectively. The first adapter 3121 and the second adapter 3122 are cylindrical and extend through the first side 3125 and the second side 3126, and the third adapter 3123 and the fourth adapter 3124 are L-shaped and extend through the first side 3125 and the third side 3127.

[0069] In this embodiment, two low-oxygen interfaces 21 and two low-oxygen through holes 11 are provided, with each low-oxygen interface 21 and each low-oxygen through hole 11 corresponding to the other. Correspondingly, two first adapter interfaces 3121 and two third adapter interfaces 3123 are also provided. When the valve seat 31 is in the first position, the two first adapter interfaces 3121 are connected to the two low-oxygen interfaces 21 and the two low-oxygen through holes 11, respectively. In this way, the air in the container 10 and the air in the oxygen control module 20 can circulate. That is, the air in the container 10 can enter the oxygen control module 20 through one first adapter interface 3121, and the low-oxygen gas generated in the oxygen control module 20 can enter the container 10 through the other first adapter interface 3121. When the valve seat 31 is in the second position, the two third adapter interfaces 3123 are connected to the two low-oxygen interfaces 21 and the outside of the container 10, respectively. The air outside the container 10 can enter the oxygen control module 20 through the two third adapter interfaces 3123.

[0070] The converter 30 also includes a fixing plate 32 fixedly disposed relative to the container 10. The valve seat 31 is slidably connected to the fixing plate 32 along a first direction. The fixing plate 32 is provided with a first mark 321 and a second mark 322 arranged along the first direction. When the valve seat 31 is in the first position, the second mark 322 is covered so that the first mark 321 is exposed. When the valve seat 31 is in the second position, the first mark 321 is covered so that the second mark 322 is exposed.

[0071] The functions of the first identifier 321 and the second identifier 322 are to show the state inside the container 10. With the above settings, when the valve seat 31 moves along the first direction to the first position and the second position, it will correspondingly cover one of the first identifier 321 and the second identifier 322, and expose the other. In this way, by observing the exposed identifier, the user can understand the state inside the container 10.

[0072] As described above, when the valve seat 31 is in the first position, the inside of the container 10 is a low-oxygen area, and when the valve seat 31 is in the second position, the inside of the container 10 is a high-oxygen area. Therefore, the first identifier 321 represents that the inside of the container 10 is a low-oxygen area, and the second identifier 322 represents that the inside of the container 10 is a high-oxygen area.

[0073] In this embodiment, the first identifier 321 is specifically the Chinese character "low oxygen", and the second identifier 322 is specifically the Chinese character "high oxygen". It can be understood that the first identifier 321 and the second identifier 322 can also use other symbols, as long as the two are different. For example, the first identifier 321 can be the letter "L", the second identifier 322 can be the letter "H", or the first identifier 321 can be the number "1", and the second identifier 322 can be the number "2".

[0074] A sliding limit structure 33 is provided between the valve seat 31 and the fixed plate 32 for limiting the movable range of the valve seat 31 relative to the fixed plate 32 from the first position to the second position.

[0075] Specifically, the sliding limit structure contains a chute formed on the fixed plate 32 and a limit strip 332 connected to the valve seat 31 and slidably disposed in the chute. In the first direction, the size occupied by the chute is larger than the size occupied by the limit strip 332. When the valve seat 31 moves relative to the fixed plate 32 along the first direction, the limit strip 332 moves with the valve seat 31 and slides in the chute. When the valve seat 31 moves to the first position and the second position, the limit strip 332 will move to the end of the chute and abut against the fixed plate 32, so that it cannot move further.

[0076] As Figure 11-18As shown, in the second specific embodiment of the present invention, the converter 30 includes a base 34 and a valve core 35 rotatably disposed within the base 34. The base 34 includes a first opening 341 communicating with the low oxygen interface 21, a second opening 342 communicating with the low oxygen through hole 11, a third opening 343 communicating with the high oxygen interface 22, a fourth opening 344 communicating with the high oxygen through hole 12, a fifth opening 345 communicating with the outside of the container 10, and a sixth opening 346. The valve core 35 can be rotated to a third position and a fourth position. When the converter 30 is in the first state, the valve core 35 is in the third position. When the converter 30 is in the second state, the valve core 35 is in the fourth position. That is, rotating the valve core 35 can switch the converter 30 between the first state and the second state, thereby controlling whether the low oxygen interface 21 and the low oxygen through hole 11 are connected and whether the high oxygen interface 22 and the high oxygen through hole 12 are connected.

[0077] Converter 30 is configured such that when valve core 35 is in the third position (e.g.) Figure 16 As shown), the first opening 341 and the second opening 342 are connected, the third opening 343 and the sixth opening 346 are connected, and the valve core 35 is in the fourth position (as shown). Figure 17 As shown), the third opening 343 and the fourth opening 344 are connected, and the first opening 341 and the fifth opening 345 are connected.

[0078] With the above configuration, when the valve core 35 is in the third position, the low oxygen port 21 and the low oxygen through hole 11 will be connected, while the high oxygen port 22 will be connected to the outside of the container 10. Thus, the low oxygen port 21 of the oxygen control module 20 can be connected to the inside of the container 10, and the air inside the container 10 can enter the oxygen control module 20 through the low oxygen port 21. The oxygen in the air entering the container 10 can be discharged to the outside of the container 10 through the high oxygen port 22 under the action of the oxygen control module 20. When the valve core 35 is in the fourth position, the high oxygen port 22 and the high oxygen through hole 12 will be connected, while the low oxygen port 21 will be connected to the outside of the container 10. The air outside the container 10 can enter the inside of the oxygen control module 20 through the low oxygen port 21, and the oxygen in the air entering the oxygen control module 20 can be discharged through the high oxygen port 22 and enter the inside of the container 10.

[0079] In this embodiment, the valve core 35 is provided with a first three-way hole 351 and a second three-way hole 352 arranged along its axial direction. The first three-way hole 351 includes a first port 3511, a second port 3512, and a third port 3513 located on the outer peripheral surface of the valve core 35. The second three-way hole 352 includes a fourth port 3521, a fifth port 3522, and a sixth port 3523 located on the outer peripheral surface of the valve core 35. The first port 3511, the second port 3512, and the third port 3513 of the first three-way hole 351 are interconnected, and the fourth port 3521, the fifth port 3522, and the sixth port 3523 of the second three-way hole 352 are interconnected.

[0080] When valve core 35 is in the third position (e.g.) Figure 16 As shown), the first port 3511 corresponds to the first opening 341, the second port 3512 corresponds to the second opening 342, the fifth port 3522 corresponds to the sixth opening 346, the sixth port 3523 corresponds to the third opening 343, and the remaining third port 3513 and fourth port 3521 are closed by the inner wall of the seat 34. Thus, the first opening 341 will be connected to the second opening 342, and the third opening 343 will be connected to the sixth opening 346.

[0081] When valve core 35 is in the fourth position (e.g.) Figure 17 As shown, the first port 3511 corresponds to the fifth opening 345, the third port 3513 corresponds to the first opening 341, the fourth port 3521 corresponds to the fourth opening 344, the fifth port 3522 corresponds to the third opening 343, and the remaining second port 3512 and sixth port 3523 are closed by the inner wall of the seat 34. Thus, the first opening 341 will be connected to the fifth opening 345, and the third opening 343 will be connected to the fourth opening 344.

[0082] Specifically, in this embodiment, the seat 34 includes a fourth side 347, a fifth side 348, a sixth side 349, and a seventh side 3410 located on its outer side. The fourth side 347 and the sixth side 349 are arranged opposite each other, and the fifth side 348 and the seventh side 3410 are arranged opposite each other. The oxygen control module 20 is located near the fourth side 347, and the container 10 is located near the sixth side 349. The first opening 341 and the third opening 343 are located on the fourth side 347, the second opening 342 and the fourth opening 344 are located on the sixth side 349, the fifth opening 345 is located on the seventh side 3410, and the sixth opening 346 is located on the fifth side 348. The first three-way hole 351 and the second three-way hole 352 are both approximately "T" shaped. The first port 3511 and the second port 3512 of the first three-way hole 351 are two ports arranged opposite each other, and the fourth port 3521 and the fifth port 3522 of the second three-way hole 352 are two ports arranged opposite each other.

[0083] It is conceivable that the positions of the first opening 341 to the sixth opening 346 and the positions of the ports of the first three-way hole 351 and the second three-way hole 352 in this embodiment are not limited to the situation described above. They can also be adjusted according to the requirements. When the valve core 35 is in the third position, the first port 3511 corresponds to the first opening 341, the second port 3512 corresponds to the second opening 342, the fifth port 3522 corresponds to the sixth opening 346, and the sixth port 3523 corresponds to the third opening 343. When the valve core 35 is in the fourth position, the first port 3511 corresponds to the fifth opening 345, the third port 3513 corresponds to the first opening 341, the fourth port 3521 corresponds to the fourth opening 344, and the fifth port 3522 corresponds to the third opening 343.

[0084] In this embodiment, both the first three-way hole 351 and the second three-way hole 352 include two interconnected channels. In other embodiments, the first three-way hole 351 can be changed into two non-interconnected first channels and second channels, and the second three-way hole 352 can be changed into two non-interconnected third channels and fourth channels. When the valve core 35 is in the third position, the first opening 341 and the second opening 342 are connected through the first channel, and the third opening 343 and the sixth opening 346 are connected through the fourth channel. When the valve core 35 is in the fourth position, the first opening 341 and the fifth opening 345 are connected through the second channel, and the third opening 343 and the fourth opening 344 are connected through the third channel.

[0085] In this embodiment, two low-oxygen interfaces 21 and two low-oxygen through holes 11 are provided. Correspondingly, two first openings 341, two second openings 342, two fifth openings 345, and two first three-way holes 351 are provided. When the valve core 35 is in the third position, the two low-oxygen interfaces 21 and the two low-oxygen through holes 11 are connected through the two first three-way holes 351 respectively. When the valve core 35 is in the fourth position, the two low-oxygen interfaces 21 are connected to the outside of the container 10 through the two first three-way holes 351 respectively. The function of providing two low-oxygen interfaces 21 and two low-oxygen through holes 11 has been explained in the first embodiment above, and will not be repeated here.

[0086] The valve core 35 is provided with a third mark 353 and a fourth mark 354 arranged in its circumferential direction. The converter 30 also includes an indicator mark 36 located on one side of the valve core 35 in the radial direction to point to the third mark 353 or the fourth mark 354. When the valve core 35 is in the third position, the indicator mark 36 points to the third mark 353. When the valve core 35 is in the fourth position, the indicator mark 36 points to the fourth mark 354.

[0087] The converter 30 includes a fixed plate 32 fixedly disposed relative to the container 10, and the aforementioned indicator 36 is disposed on the fixed plate 32. Specifically, the indicator 36 may be an arrow.

[0088] The functions of the third identifier 353 and the fourth identifier 354 are to show the state inside the container 10. When the converter 30 is in the first state, the valve core 35 is in the third position, and the indicating identifier 36 points to the third identifier 353. When the converter 30 is in the second state and the valve core 35 is in the fourth position, the indicating identifier 36 points to the fourth identifier 354. In this way, by observing whether the indicating identifier 36 points to the third identifier 353 or the fourth identifier 354, the user can understand the state inside the container 10.

[0089] When the indicating identifier 36 points to the third identifier 353, it indicates that the inside of the container 10 is a low-oxygen area. When the indicating identifier 36 points to the fourth identifier 354, it indicates that the inside of the container 10 is a high-oxygen area.

[0090] In this embodiment, the third identifier 353 is specifically the Chinese character "low", and the fourth identifier 354 is specifically the Chinese character "high". It can be understood that the third identifier 353 and the fourth identifier 354 can also adopt other symbols, as long as the two are distinguishable. For example, the third identifier 353 can be the letter "L", the fourth identifier 354 can be the letter "H", or the third identifier 353 can be the number "1", and the fourth identifier 354 can be the number "2".

[0091] The valve seat 31 includes an extending portion 355 that extends outside the seat body 34, and an anti-slip pattern 3351 is formed on the outer periphery of the extending portion 355. When the converter 30 is in use, the user manually turns the extending portion 355 to switch between the third position and the fourth position, and the anti-slip pattern 3351 can prevent slipping when the extending portion 355 is turned.
