Description

Baking equipment

[0001] This application claims priority to Chinese Patent Application No. 202520522431.8, filed on March 24, 2025, entitled “Baking Equipment”, which is incorporated herein by reference in its entirety. Technical Field

[0002] This application relates to the field of electrode drying technology, specifically to a baking device. Background Technology

[0003] In the manufacturing process of battery electrode sheets, baking equipment is usually used to bake the electrode sheets to remove residual solvents. During the baking process, the baking chamber needs to be evacuated to create a vacuum state, thereby lowering the boiling point of the solvent and improving the drying efficiency of the electrode sheets.

[0004] In related technologies, in order to enable the door to withstand the pressure difference between the internal and external environments of the baking equipment, the baking equipment usually adopts a heavy door structure to reduce the risk of door deformation or damage. However, during long-term use, the door is prone to sinking or tilting due to its excessive weight, which reduces the sealing effect of the door on the baking cavity. Therefore, how to reduce the risk of the door sinking or tilting in order to improve the sealing effect of the door on the baking cavity is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] In view of the above problems, this application provides a baking device to reduce the risk of the door sinking or tilting, thereby improving the sealing effect of the door on the baking cavity.

[0006] This application provides a baking device, comprising: a housing having a baking cavity and an opening communicating with the baking cavity; a door connected to the housing for opening or closing the opening; and a first support assembly including a first support member and a second support member, the first support member being disposed on the housing and the second support member being disposed on the door. When the door is closed, the second support member rests on the side of the first support member near the top of the housing. By disposing the first support member on the housing and the second support member on the door, and when the door is closed, resting the second support member on the side of the first support member near the top of the housing, the second support member can transfer the weight of the door to the first support member, which is then distributed to the housing. This achieves the transfer of part of the weight of the door to the housing, reducing the risk of the door sinking or tilting due to excessive weight during long-term use. Furthermore, the weight transferred from the door to the housing creates pressure on the housing, ensuring a tight seal between the door and the housing, thereby improving the sealing effect of the door on the baking cavity.

[0007] In some embodiments, the baking equipment further includes a hinge assembly connected between the housing and the door. A first support member is disposed on the side of the housing away from the hinge assembly, and a second support member is disposed on the side of the door away from the hinge assembly. This arrangement allows the first and second support members to support the side of the door away from the hinge assembly when the door is closed, thereby reducing the risk of sinking or tilting on that side. Furthermore, the first and second support members can transfer some of the door's weight to the housing. This transferred weight not only exerts pressure on the housing, ensuring a tight fit between the door and the housing, but also reduces the load on the hinge assembly, decreasing the door's dependence on it. This reduces the risk of damage to the hinge assembly due to prolonged exposure to the full load of the door, thus extending its service life.

[0008] In some embodiments, the first support member is disposed on the side of the housing away from the top, and the second support member is disposed on the side of the door away from the top. This arrangement allows the first and second support members to support the bottom of the door when it is closed, reducing the risk of the door sinking or tilting. Furthermore, the first and second support members can transfer some of the door's weight to the housing. This transferred weight not only creates pressure on the housing, ensuring a tight fit between the door and the housing, but also reduces the load on the hinge assembly, decreasing the door's dependence on the hinge assembly. This reduces the risk of damage to the hinge assembly due to prolonged exposure to the full load of the door, thus extending the hinge assembly's service life.

[0009] In some embodiments, one of the first support member and the second support member is provided with a first rolling part, and the other of the first support member and the second support member is provided with a first bearing surface. When the door is in the closed state, the first rolling part abuts against the first bearing surface. By providing a first rolling part on one of the first support member and the second support member, and a first bearing surface on the other of the first support member and the second support member, the first rolling part can roll along the first bearing surface during the closing process of the door and abut against the first bearing surface when the door is in the closed state. On the one hand, the friction between the first support member and the second support member can be reduced, making the closing process of the door smoother. This not only reduces the risk of wear or deformation of the first support member and the second support member, but also reduces the impact force on the box when the door is closed, reducing the risk of wear or deformation of the door and the box due to excessive impact force. On the other hand, the first rolling part can convert the rolling friction between itself and the first bearing surface into a supporting force for the door, thereby reducing the risk of the door sinking or tilting.

[0010] In some embodiments, the second support member has a first rolling portion, and the first support member has a first bearing surface and a guide surface connecting the first bearing surface. The guide surface is bent from the side of the first bearing surface away from the housing towards the direction away from the top. The guide surface can guide the first rolling portion to roll toward the first bearing surface during the closing of the door, so that the first rolling portion rolls smoothly onto the first bearing surface and is supported on the first bearing surface. This achieves a smooth transition of the first rolling portion from a rolling state to a stationary support state, reducing the risk of collision or impact between the first rolling portion and the first support member, thereby reducing noise and structural wear, and helping to extend the service life of the first support member and the second support member.

[0011] In some embodiments, one of the first support member and the second support member further includes: a first mounting base, including two first mounting portions disposed opposite to each other and spaced apart; a first rotating shaft connected between the two first mounting portions; wherein the first rolling portion includes a first rolling bearing, the first rolling bearing being sleeved on the first rotating shaft, the axial direction of the first rolling bearing being parallel to the first bearing surface and perpendicular to the axial direction of the opening. By configuring the first rolling portion to include the first rolling bearing, and making the axial direction of the first rolling bearing parallel to the first bearing surface and perpendicular to the axial direction of the opening, the first rolling bearing can roll along the axial direction of the opening on the first bearing surface during the closing process of the door. On the one hand, making the movement trajectory of the first rolling bearing parallel to the axial direction of the opening helps to further reduce the frictional loss between the first support member and the second support member, making the closing process of the door easier; on the other hand, the first rolling bearing can withstand the vertical gravity generated by the weight of the door and transfer part of the weight of the door to the housing, which can effectively reduce the risk of the door sinking or tilting due to excessive weight during long-term use.

[0012] In some embodiments, the door includes: a door body; a sealing plate connected to the side of the door body near the housing; and a floating mechanism disposed between the door body and the sealing plate. By disposing the floating mechanism between the door body and the sealing plate, the floating mechanism can drive the sealing plate to float towards the housing when the door is in the closed state, and fit against the edge of the opening communicating with the baking cavity to seal the baking cavity, thereby effectively improving the sealing effect and reliability of the door to the baking cavity.

[0013] In some embodiments, the door further includes a second support assembly disposed between the door body and the sealing plate. The second support assembly is at least partially disposed on the sealing plate and is rotatably supported on the door body. By disposing at least partially on the sealing plate and being rotatably supported on the door body, the second support assembly can roll along a preset trajectory as the sealing plate floats during the floating mechanism's operation. This reduces friction between the sealing plate and the door body, improving the smoothness of the sealing plate's floating and reducing the risk of wear or deformation between the sealing plate and the door body. Furthermore, the second support assembly provides support for the sealing plate, allowing it to fit more tightly and stably against the edge of the opening, further improving the door's sealing effect on the baking cavity.

[0014] In some embodiments, the second support assembly includes: a third support member disposed on the side of the door body facing the sealing plate; and a fourth support member disposed on the side of the sealing plate facing the door body. One of the third and fourth support members is provided with a second rolling portion, and the other of the third and fourth support members is provided with a second bearing surface. The second rolling portion can roll against the second bearing surface. This arrangement allows the second rolling portion to roll on the second bearing surface as the sealing plate floats during the floating mechanism's operation. On one hand, this reduces the friction between the sealing plate and the door body, improving the smoothness of the sealing plate's floating and reducing the risk of wear or deformation between the sealing plate and the door body. On the other hand, the third support member provides support for the sealing plate, and the fourth support member transfers part of the sealing plate's weight to the door body, reducing the risk of deformation or sinking of the sealing plate during long-term floating. This allows the sealing plate to fit more tightly and stably against the edge of the opening, further improving the sealing effect of the door on the baking cavity and extending the door's service life.

[0015] In some embodiments, one of the third support member and the fourth support member further includes: a second mounting base, including two second mounting portions that are opposite to each other and spaced apart; a second rotating shaft connected between the two second mounting portions; wherein the second rolling portion includes a second rolling bearing, the second rolling bearing is sleeved on the second rotating shaft, the axial direction of the second rolling bearing is parallel to the second bearing surface and perpendicular to the arrangement direction of the door body and the sealing plate. By configuring the second rolling part to include a second rolling bearing, with the axis of the second rolling bearing parallel to the second bearing surface and perpendicular to the arrangement direction of the door body and the sealing plate, the second rolling bearing can roll along the arrangement direction of the door body and the sealing plate on the second bearing surface during the floating process driven by the floating mechanism to float the sealing plate. On the one hand, making the movement trajectory of the second rolling bearing parallel to the floating direction of the sealing plate helps to further reduce the frictional loss between the third support and the fourth support, reducing the risk of jamming during the floating of the sealing plate, thereby effectively improving the smoothness of the floating of the sealing plate. On the other hand, the second rolling bearing can transfer part of the weight of the sealing plate to the door body, reducing the risk of deformation or sinking of the sealing plate during long-term floating, thereby allowing the sealing plate to fit more tightly and stably against the edge of the opening, which is beneficial to extending the service life of the door.

[0016] In some embodiments, the second support assembly further includes a first fixing rod disposed on the side of the sealing plate facing the door body and extending axially along the second rolling bearing, and a fourth support member disposed on the side of the first fixing rod near the third support member. This arrangement enhances the bending strength of the sealing plate in the extension direction of the first fixing rod and reduces the risk of deformation of the sealing plate due to floating.

[0017] In some embodiments, the floating mechanism includes an elastic component connected between the door body and the sealing plate. The elastic component provides a pressing force towards the housing to the sealing plate when the door is closed. This arrangement allows the sealing plate to float towards the housing and fit tightly against the edge of the opening, effectively improving the door's effect on the baking cavity. Furthermore, the elastic component can automatically adjust the compression amount according to the flatness of the opening edge, effectively improving the sealing strength between the sealing plate and the opening edge.

[0018] In some embodiments, a receiving cavity is formed between the door body and the sealing plate, and a floating mechanism is disposed within the receiving cavity; the door body includes two side plates disposed opposite to each other on both sides of the receiving cavity; the floating mechanism further includes a second fixing rod connected between the two side plates, and an elastic component disposed between the second fixing rod and the sealing plate. The second fixing rod can provide stable support for the elastic component and transfer part of the elastic restoring force generated when the elastic component contracts to the door body, reducing the risk of damage to the elastic component or uneven stress on the sealing plate due to stress accumulation at the end of the elastic component near the door body.

[0019] In some embodiments, the elastic component includes: a positioning post, one end of which is fixed to the side of the second fixing rod facing the sealing plate, and the other end extending towards the sealing plate and spaced apart from it; and an elastic body, sleeved over the positioning post, with one end abutting against the positioning post or the second fixing rod and the other end abutting against the sealing plate. By providing a positioning post on the side of the second fixing rod facing the sealing plate and sleeved over the positioning post, the positioning post can guide the elastic body, allowing it to compress or reset along the arrangement direction of the sealing plate and the door body. This reduces the risk of lateral displacement or twisting of the elastic body during compression or reset, making the floating trajectory of the sealing plate controllable during door closing. This not only improves the stability of the sealing plate during floating but also enhances its sealing effect. By spaced the positioning post from the sealing plate, the gap between them provides contraction space for the elastic body, reducing the risk of elastic body failure due to contraction.

[0020] In some embodiments, the floating mechanism includes a plurality of second fixed rods extending along a first direction and spaced apart sequentially along a second direction. Each second fixed rod is provided with a plurality of elastic components between itself and the sealing plate, and these elastic components are also spaced apart sequentially along the first direction. The second direction is parallel to the arrangement direction of the top and bottom of the housing and perpendicular to the first direction. This arrangement allows the multiple elastic components to be distributed at multiple positions between the sealing plate and the door body. On the one hand, the multiple elastic components can automatically adjust the compressive force according to the force applied, further improving the sealing effect of the sealing plate on the baking cavity. On the other hand, when one elastic component becomes fatigued or damaged, the remaining elastic components can still maintain the pressure on the sealed door towards the housing, giving the door fault tolerance and reducing the risk of air leakage in the baking cavity due to the sealed door failing to float towards the housing during operation. Furthermore, the multiple elastic components can share the thrust of the housing towards the door, mitigating the fatigue and aging rate of the elastic components and helping to extend the service life of the door.

[0021] In some embodiments, the door further includes a limiting component disposed between the door body and the sealing plate, with at least a portion of the limiting component extending to the side of the sealing plate facing away from the door body. The limiting component can limit the floating range of the sealing plate when it floats towards the housing, reducing the risk of the sealing plate tilting or misaligning relative to the edge of the opening due to excessive floating displacement towards the housing, thereby reducing the likelihood of sealing failure.

[0022] In some embodiments, a clearance groove is formed on the side of the sealing plate facing away from the door body; the limiting component includes: a fixing part disposed on the door body; and a limiting body disposed on the side of the fixing part near the sealing plate and extending at least partially into the clearance groove. When the door is in the open state, there is a gap between the limiting body and the bottom wall of the clearance groove. By providing a clearance groove on the side of the sealing plate facing away from the door body and extending the limiting body of the limiting component into the clearance groove, and ensuring a gap between the limiting body and the bottom wall of the clearance groove when the door is in the open state, the gap between the limiting body and the clearance groove provides floating space for the sealing plate towards the housing during the closing process, allowing the sealing plate to float within the floating space defined by the limiting component.

[0040] In the manufacturing process of battery electrode sheets, active materials, typically in the form of a slurry, are first coated onto the current collector surface using a coating device. Since the slurry contains solvents, these solvents remain on the electrode sheets after coating. The solvents can react with the electrolyte, causing corrosion of the electrode sheets or leading to gas expansion inside the battery, thus affecting battery stability. To remove the residual solvents from the electrode sheets, a baking process is usually employed. During baking, the baking chamber is evacuated to create a vacuum, thereby lowering the boiling point of the solvent and improving the drying efficiency of the electrode sheets.

[0041] In related technologies, in order to enable the door to withstand the pressure difference between the inside and outside environment of the baking equipment, the baking equipment usually adopts a heavy door structure to reduce the risk of door deformation or damage; however, during long-term use, the door is prone to sinking or tilting due to its excessive weight, which reduces the sealing effect of the door on the baking cavity.

[0042] Based on the above considerations, this application provides a baking device. The baking device includes a housing, a door, and a first support assembly. The housing forms a baking cavity and an opening communicating with the baking cavity. The door is connected to the housing and is used to open or close the opening. The first support assembly includes a first support member and a second support member. The first support member is disposed on the housing, and the second support member is disposed on the door. When the door is closed, the second support member is supported on the side of the first support member near the top of the housing. By placing the first support member on the cabinet and the second support member on the door, and when the door is closed, the second support member is supported on the side of the first support member near the top of the cabinet. The second support member can transfer the weight of the door to the first support member, and then the first support member distributes it to the cabinet. This transfers part of the weight of the door to the cabinet, which not only reduces the risk of the door sinking or tilting due to excessive weight during long-term use, but also creates pressure on the cabinet due to the weight of the door, allowing the door to fit tightly against the cabinet and improving the sealing effect of the door on the baking cavity.

[0043] The baking equipment of this application embodiment can be used to bake electrode sheets during the battery production process. It can at least reduce the risk of door sinking or tilting during long-term use, thereby improving the sealing effect of the door on the baking cavity.

[0044] The electrode sheets dried by the baking equipment disclosed in this application can be used in batteries. These batteries can be used in electrical devices that use batteries as a power source or in various energy storage systems that use batteries as energy storage elements. Electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0045] For ease of explanation, the following embodiments use a baking device according to an embodiment of this application as an example.

[0046] Referring to Figures 1 to 3, this application provides a baking apparatus 1000. The baking apparatus 1000 includes a housing 100, a door 200, and a first support assembly 300. The housing 100 forms a baking cavity 100a and an opening 100b communicating with the baking cavity 100a. The door 200 is connected to the housing 100 and is used to open or close the opening 100b. The first support assembly 300 includes a first support member 310 and a second support member 320. The first support member 310 is disposed on the housing 100, and the second support member 320 is disposed on the door 200. When the door 200 is in the closed state, the second support member 320 is supported on the side of the first support member 310 near the top of the housing 100.

[0047] The housing 100 has a baking cavity 100a and an opening 100b communicating with the baking cavity 100a. A door 200 is connected to the side of the housing 100 with the opening 100b for opening or closing the opening 100b. When the door 200 is in the closed state, it can close the opening 100b to seal it, so that the baking cavity 100a is in a relatively closed state.

[0048] The first support member 310 can be disposed on the side wall 120 of the housing 100; or, the first support member 310 can also be disposed on the door frame 110 which is on the same side as the opening 100b and surrounds the opening 100b. The second support member 320 is disposed on the door 200 and is disposed corresponding to the first support member 310.

[0049] The top of the box 100 is located on the upper side of the baking equipment 1000 along the direction of gravity, and correspondingly, the bottom of the box 100 is located on the lower side of the baking equipment 1000 along the direction of gravity. The top and bottom of the box 100 are arranged opposite each other along the direction of gravity. When the box 100 is in the closed state, the second support member 320 provided on the door 200 is supported on the side of the first support member 310 provided on the box 100 near the top of the box 100, and the projection of the second support member 320 toward the bottom of the box 100 is at least partially located on the first support member 310, so that the second support member 320 can transfer the weight of the door 200 to the first support member 310.

[0050] The baking equipment 1000 may include a plurality of first support components 300. The plurality of first support components 300 may be disposed on the side of the baking equipment 1000 away from the hinge assembly 400, that is, a plurality of first support members 310 are disposed on the side of the housing 100 away from the hinge assembly 400, and are arranged sequentially at intervals along the arrangement direction of the top and bottom of the housing 100. A plurality of second support members 320 are disposed on the side of the door 200 away from the hinge assembly 400, and when the door 200 is in the closed state, the plurality of second support members 320 are supported on the side of the corresponding first support member 310 near the top of the housing 100; alternatively, the plurality of first support components 300 may also be disposed on the side of the baking equipment 1000 away from the top. That is, multiple first support members 310 are disposed on the side of the box 100 away from the top, and are arranged at intervals in a direction perpendicular to the arrangement direction of the top and bottom. Multiple second support members 320 are disposed on the side of the door 200 away from the top of the box 100, and when the door 200 is in the closed state, the multiple second support members 320 are supported on the side of the corresponding first support member 310 near the top of the box 100; or, a portion of the multiple first support components 300 may be disposed on the side of the baking device 1000 away from the hinge assembly 400, and another portion may be disposed on the side of the baking device 1000 away from the hinge assembly 400.

[0051] By placing the first support member 310 on the housing 100 and the second support member 320 on the door 200, and when the door 200 is closed, the second support member 320 is supported on the side of the first support member 310 near the top of the housing 100. The second support member 320 can transfer the weight of the door 200 to the first support member 310, and then the first support member 310 distributes it to the housing 100. This transfers part of the weight of the door 200 to the housing 100, which not only reduces the risk of the door 200 sinking or tilting due to excessive weight during long-term use, but also creates pressure on the housing 100 due to the weight of the door 200, allowing the door 200 to fit tightly against the housing 100, thereby improving the sealing effect of the door 200 on the baking cavity 100a.

[0052] In some embodiments, please continue to refer to Figures 1 and 2. The baking apparatus 1000 further includes a hinge assembly 400, which is connected between the housing 100 and the door 200. A first support member 310 is disposed on the side of the housing 100 away from the hinge assembly 400, and a second support member 320 is disposed on the side of the door 200 away from the hinge assembly 400.

[0053] The door 200 is connected to the housing 100 via a hinge assembly 400. The hinge assembly 400 not only provides the door 200 with a rotation function, allowing the door 200 to rotate relative to the housing 100 so that the door 200 can open or close the opening 100b, but also provides support for the door 200 so that the door 200 will not fall or wobble during opening and closing, thereby improving the reliability of the door 200.

[0054] The first support member 310 may be disposed on the side wall 120 of the housing 100 away from the hinge assembly 400; or, the first support member 310 may be disposed on the door frame 110 of the housing 100 away from the hinge assembly 400. The second support member 320 may be disposed on the end of the door 200 away from the hinge assembly 400.

[0055] By placing the first support member 310 on the side of the housing 100 away from the hinge assembly 400 and the second support member 320 on the side of the door 200 away from the hinge assembly 400, when the door 200 is closed, the first support member 310 and the second support member 320 can support the side of the door 200 away from the hinge assembly 400, thereby reducing the risk of sinking or tilting on the side of the door 200 away from the hinge assembly 400; furthermore, the first support member 310 and the second support member 320... The support member 320 can transfer part of the weight of the door 200 to the housing 100. The weight transferred from the door 200 to the housing 100 not only creates pressure on the housing 100, allowing the door 200 to fit tightly against the housing 100, but also reduces the load on the hinge assembly 400, reduces the dependence of the door 200 on the hinge assembly 400, thereby reducing the risk of damage to the hinge assembly 400 due to long-term bearing of the full load of the door 200, and can extend the service life of the hinge assembly 400.

[0056] In some embodiments, the first support member 310 is disposed on the side of the housing 100 away from the top, and the second support member 320 is disposed on the side of the door 200 away from the top of the housing 100.

[0057] The first support member 310 can be installed on the door frame 110 on the side of the box 100 away from the top, and the second support member 320 can be installed on the end of the door 200 on the side away from the top of the box 100.

[0058] By placing the first support member 310 on the side of the housing 100 away from the top and the second support member 320 on the side of the door 200 away from the top of the housing 100, the first support member 310 and the second support member 320 can support the bottom of the door 200 when the door 200 is closed, reducing the risk of the door 200 sinking or tilting. Furthermore, the first support member 310 and the second support member 320 can transfer part of the weight of the door 200 to the housing 100. The weight transferred from the door 200 to the housing 100 not only creates pressure on the housing 100, allowing the door 200 to fit tightly against the housing 100, but also reduces the load on the hinge assembly 400, decreasing the door 200's dependence on the hinge assembly 400. This reduces the risk of the hinge assembly 400 being damaged due to bearing the full load of the door 200 for a long time, thus extending the service life of the hinge assembly 400.

[0059] In some embodiments, referring to Figure 3, one of the first support member 310 and the second support member 320 is provided with a first rolling portion 321. The other of the first support member 310 and the second support member 320 is provided with a first bearing surface 311. When the door 200 is in the closed state, the first rolling portion 321 abuts against the first bearing surface 311.

[0060] When the first rolling part 321 is provided on the first support member 310, the first bearing surface 311 is provided on the second support member 320, and the first rolling part 321 is located on the side of the first support member 310 near the top of the box 100, while the first bearing surface 311 is located on the side of the second support member 320 away from the top of the box 100; when the first rolling part 321 is provided on the second support member 320, the first bearing surface 311 is provided on the first support member 310, and the first rolling part 321 is located on the side of the second support member 320 away from the top of the box 100, while the first bearing surface 311 is located on the side of the first support member 310 near the top of the box 100.

[0061] During the closing process of the door 200, when the door 200 is closed to a set angle, the first rolling part 321 can contact the first bearing surface 311 and roll along the first bearing surface 311. Since the first rolling part 321 generates rolling friction with the first bearing surface 311 when rolling, it can reduce the friction between the second support member 320 and the first support member 310. When the door 200 is in the closed state, that is, when the door 200 is closed in place, the side of the door 200 close to the box 100 is in contact with the box 100, which can prevent the first rolling part 321 from continuing to roll along the first bearing surface 311, so that the first rolling part 321 abuts against the first bearing surface 311, thereby allowing the first rolling part 321 to convert the rolling friction between itself and the first bearing surface 311 into a supporting force for the door 200.

[0062] By providing a first rolling part 321 on one of the first support member 310 and the second support member 320, and providing a first bearing surface 311 on the other of the first support member 310 and the second support member 320, the first rolling part 321 can roll along the first bearing surface 311 during the closing process of the door 200, and abut against the first bearing surface 311 when the door 200 is in the closed state. On the one hand, this reduces the friction between the first support member 310 and the second support member 320, thus improving the stability of the door 200. The closing process is smoother, which not only reduces the risk of wear or deformation of the first support member 310 and the second support member 320, but also reduces the impact force on the box 100 when the door 200 is closed, reducing the risk of wear or deformation of the door 200 and the box 100 due to excessive impact force. On the other hand, the first rolling part 321 can convert the rolling friction between itself and the first bearing surface 311 into a supporting force for the door 200, thereby reducing the risk of the door 200 sinking or tilting.

[0063] In some embodiments, please continue to refer to FIG3, the second support member 320 is provided with a first rolling part 321, and the first support member 310 is provided with a first bearing surface 311 and a guide surface 312. The guide surface 312 is bent from the side of the first bearing surface 311 away from the box body 100 toward the top away from the box body 100.

[0064] The guide surface 312 is connected to the side of the first bearing surface 311 away from the housing 100, and is curved from the side of the first bearing surface 311 away from the housing 100 toward the top away from the housing 100. The guide surface 312 can serve as a front end extension of the first bearing surface 311, and can be used to guide the first rolling part 321 to roll toward the first bearing surface 311 during the closing of the door 200, so that the first rolling part 321 abuts against and is supported on the first bearing surface 311.

[0065] In some embodiments, a first rolling portion 321 is provided on a first support member 310, a first bearing surface 311 and a guide surface 312 are provided on a second support member 320, and the guide surface 312 is bent from the side of the first bearing surface 311 away from the housing 100 toward the top of the housing 100.

[0066] In some embodiments, the connection between the guide surface 312 and the first bearing surface 311 is smoothly arranged, which not only allows the first rolling part 321 to pass smoothly through the connection between the guide surface 312 and the first bearing surface 311, but also alleviates or eliminates the vibration of the first rolling part 321 during the process of rolling from the guide surface 312 to the first bearing surface 311, which helps to improve the stability of the door 200 during the closing process.

[0067] By providing a first bearing surface 311 and a guide surface 312 on the first support member 310, and with the guide surface 312 bent from the side of the first bearing surface 311 away from the box body 100 toward the top away from the box body 100, the guide surface 312 can guide the first rolling part 321 to roll toward the first bearing surface 311 during the closing of the door body 200, so that the first rolling part 321 rolls smoothly onto the first bearing surface 311 and is supported on the first bearing surface 311. This achieves a smooth transition of the first rolling part 321 from the rolling state to the static support state, which can reduce the risk of collision or impact between the first rolling part 321 and the first support member 310, thereby reducing noise and structural wear, and helping to extend the service life of the first support member 310 and the second support member 320.

[0068] In some embodiments, referring to Figure 3, one of the first support member 310 and the second support member 320 further includes a first mounting base 322 and a first rotating shaft 324. The first mounting base 322 includes two first mounting portions 323 that are opposite to each other and spaced apart. The first rotating shaft 324 is connected between the two first mounting portions 323. The first rolling portion 321 includes a first rolling bearing 3211, which is sleeved on the outside of the first rotating shaft 324. The axial direction of the first rolling bearing 3211 is parallel to the first bearing surface 311 and perpendicular to the axial direction of the opening 100b.

[0069] In this embodiment, one of the first support member 310 and the second support member 320 is the one that has a first rolling part 321. For ease of description, the following embodiment uses the one with the first rolling part 321 as the second support member 320, with the second support member 320 located on the side of the door body 200 away from the hinge assembly 400, and the first support member 310 located on the side of the box body 100 away from the hinge assembly 400 as an example.

[0070] The second support member 320 includes a first mounting base 322 and a first rotating shaft 324. The first mounting base 322 is fixed to the side of the door body 200 away from the hinge assembly 400, and extends at least partially in a direction away from the hinge assembly 400. Two first mounting portions 323 are provided on the portion of the first mounting base 322 extending away from the hinge assembly 400. The two first mounting portions 323 are spaced apart along the arrangement direction of the side of the door body 200 connected to the hinge assembly 400 and the side where the second support member 320 is provided, and the two first mounting portions 323 form corresponding shaft holes. The two ends of the first rotating shaft 324 are fixed in the shaft holes of the corresponding first mounting portions 323. A first rolling bearing 3211 is sleeved on the outside of the first rotating shaft 324 and can rotate circumferentially along the first rotating shaft 324. The axial direction of the first rolling bearing 3211 is parallel to the first bearing surface 311 and perpendicular to the axial direction of the opening 100b; wherein, the axial direction of the opening 100b is parallel to the arrangement direction of the door body 200 and the box body 100 when the door body 200 is in the closed state.

[0071] The first mounting base 322 can be fixed to the door body 200 by welding, riveting, bolting, magnetic adsorption or adhesive connection, but is not limited to these methods.

[0072] By configuring the first rolling part 321 to include a first rolling bearing 3211, and making the axial direction of the first rolling bearing 3211 parallel to the first bearing surface 311 and perpendicular to the axial direction of the opening 100b, the first rolling bearing 3211 can roll along the axial direction of the opening 100b on the first bearing surface 311 during the closing process of the door 200. On the one hand, making the movement trajectory of the first rolling bearing 3211 parallel to the axial direction of the opening 100b helps to further reduce the frictional loss between the first support member 310 and the second support member 320, making the closing process of the door 200 easier. On the other hand, the first rolling bearing 3211 can withstand the vertical gravity generated by the weight of the door 200 and transfer part of the weight of the door 200 to the housing 100, which can effectively reduce the risk of the door 200 sinking or tilting due to excessive weight during long-term use.

[0073] In some embodiments, referring to FIG4, the door 200 includes a door body 210, a sealing plate 220, and a floating mechanism 230. The sealing plate 220 is connected to the side of the door body 210 near the housing 100. The floating mechanism 230 is disposed between the door body 210 and the sealing plate 220.

[0074] When the door 200 is closed, the sealing plate 220 is located on the side of the door body 210 closest to the box 100.

[0075] The door body 210 can serve as the rigid frame of the door 200, and can provide a certain degree of rigid support for the sealing plate 220. The material of the door body 210 can be selected from metals with high strength, high temperature resistance and deformation resistance, such as high-temperature resistant stainless steel and aluminum alloy, but is not limited to these.

[0076] The sealing plate 220 can serve as a sealing structure for the door 200. The material of the sealing plate 220 can be selected from non-metals or metals possessing properties such as high temperature resistance and flexibility, including polyimide, polyetheretherketone, and stainless steel, but is not limited to these. When the material of the sealing plate 220 is stainless steel, the surface of the sealing plate 220 can be polished, or an elastic sealing element can be provided on the side of the sealing plate 220 facing the housing 100.

[0077] During the closing process of the door 200, when the side of the sealing plate 220 facing away from the door body 210 contacts the edge of the opening 100b, the edge of the opening 100b exerts a pushing force on the floating mechanism 230, triggering the floating mechanism 230 to drive the sealing plate 220 to float towards the housing 100. When the door 200 opens, the pushing force of the edge of the opening 100b on the floating mechanism 230 disappears, the floating mechanism 230 returns to its natural state, and drives the sealing plate 220 to float towards the door body 210. The edge of the opening 100b can be a portion of the housing 100 surrounding the opening 100b, or it can be the door frame 110.

[0078] By placing the floating mechanism 230 between the door body 210 and the sealing plate 220, the floating mechanism 230 can drive the sealing plate 220 to float toward the box 100 when the door body 200 is in the closed state, and fit against the edge of the opening 100b of the baking cavity 100a to seal the baking cavity 100a, which can effectively improve the sealing effect and reliability of the door body 200 to the baking cavity 100a.

[0079] In some embodiments, referring to FIG4, the door body 200 further includes a second support assembly 250. The second support assembly 250 is disposed between the door body 210 and the sealing plate 220, and the second support assembly 250 is at least partially disposed on the sealing plate 220 and is rotatably supported on the door body 210.

[0080] The second support assembly 250 is supported on the door body 210, and during the floating process of the floating mechanism 230 driving the sealing plate 220 to float, the second support assembly 250 can roll along a preset trajectory as the sealing plate 220 floats. Specifically, when the floating mechanism 230 drives the sealing plate 220 to float towards the housing 100 and when the floating mechanism 230 drives the sealing plate 220 to float towards the door body 210, the second support assembly 250 can roll along the preset trajectory as the sealing plate 220 floats.

[0081] By at least partially placing the second support component 250 on the sealing plate 220 and providing rollable support to the door body 210, the second support component 250 can roll along a preset trajectory as the sealing plate 220 floats during the floating process driven by the floating mechanism 230. On the one hand, this reduces the friction between the sealing plate 220 and the door body 210, which not only improves the smoothness of the floating of the sealing plate 220 but also reduces the risk of wear or deformation between the sealing plate 220 and the door body 210. On the other hand, the second support component 250 can support the sealing plate 220, allowing the sealing plate 220 to fit more tightly and stably against the edge of the opening 100b, further improving the sealing effect of the door body 200 on the baking cavity 100a.

[0082] In some embodiments, referring to Figure 4 and also Figures 5 and 6, the second support assembly 250 includes a third support member 251 and a fourth support member 252. The third support member 251 is located on the side of the door body 210 facing the sealing plate 220. The fourth support member 252 is located on the side of the sealing plate 220 facing the door body 210. One of the third support member 251 and the fourth support member 252 has a second rolling portion 2521, and the other of the third support member 251 and the fourth support member 252 has a second bearing surface 2511. The second rolling portion 2521 can roll against the second bearing surface 2511.

[0083] The third support member 251 and the fourth support member 252 are arranged parallel to the arrangement direction of the top and bottom of the box body 100. Along the arrangement direction of the top and bottom of the box body 100, the fourth support member 252 located on the sealing plate 220 is closer to the top of the box body 100 than the third support member 251 located on the door body 210, so that the fourth support member 252 can be supported on the third support member 251.

[0084] When the second rolling part 2521 is provided on the third support member 251, the second bearing surface 2511 is provided on the fourth support member 252; when the second rolling part 2521 is provided on the fourth support member 252, the second bearing surface 2511 is provided on the third support member 251. The second rolling part 2521 can roll against the second bearing surface 2511. During the process of the floating mechanism 230 driving the sealing plate 220 to float, the second rolling part 2521 can roll on the second bearing surface 2511 as the sealing plate 220 floats.

[0085] By providing a second rolling part 2521 on one of the third support member 251 and the fourth support member 252, and providing a second bearing surface 2511 on the other of the third support member 251 and the fourth support member 252, the second rolling part 2521 can roll on the second bearing surface 2511 as the sealing plate 220 floats during the floating process driven by the floating mechanism 230. On the one hand, this reduces the friction between the sealing plate 220 and the door body 210, thereby improving the smoothness of the floating of the sealing plate 220 and reducing the friction between the sealing plate 220 and the door body 210. There is a risk of wear or deformation between the main bodies 210; on the other hand, the third support 251 can support the sealing plate 220, and the fourth support 252 can transfer part of the weight of the sealing plate 220 to the door body 210 through the third support 251, which can reduce the risk of deformation or sinking of the sealing plate 220 during long-term floating, so that the sealing plate 220 can fit more tightly and stably with the edge of the opening 100b, which can further improve the sealing effect of the door body 200 on the baking cavity 100a and help extend the service life of the door body 200.

[0086] In some embodiments, one of the third support member 251 and the fourth support member 252 further includes a second mounting base 2522 and a second rotating shaft 2524. The second mounting base 2522 includes two opposing and spaced-apart second mounting portions 2523, and the second rotating shaft 2524 connects the two second mounting portions 2523. The second rolling portion 2521 includes a second rolling bearing 2521a, which is sleeved on the second rotating shaft 2524. The axial direction of the second rolling bearing 2521a is parallel to the second bearing surface 2511 and perpendicular to the arrangement direction of the door body 210 and the sealing plate 220.

[0087] In this embodiment, one of the third support member 251 and the fourth support member 252 is the one that has a second rolling part 2521. For ease of description, the following embodiment will be described using the fourth support member 252 as an example, where the one with the second rolling part 2521 is provided.

[0088] The fourth support member 252 includes a second mounting base 2522 and a second rotating shaft 2524. The second mounting base 2522 is fixed to the side of the sealing plate 220 facing the door body 210 and extends at least partially toward the third support member 251. Two second mounting portions 2523 are provided on the portion of the second mounting base 2522 extending toward the third support member 251. The two second mounting portions 2523 are spaced apart along the arrangement direction of the side of the door body 200 connected to the hinge assembly 400 and the side where the second support member 320 is provided, and the two second mounting portions 2523 form corresponding shaft holes. The two ends of the second rotating shaft 2524 are fixed in the shaft holes of the corresponding second mounting portions 2523. A second rolling bearing 2521a is sleeved on the second rotating shaft 2524 and can rotate circumferentially along the second rotating shaft 2524. The axial direction of the second rolling bearing 2521a is parallel to the second bearing surface 2511 and perpendicular to the arrangement direction of the door body 210 and the sealing plate 220; wherein, the arrangement direction of the door body 210 and the sealing plate 220 is also the floating direction of the sealing plate 220.

[0089] By configuring the second rolling part 2521 to include a second rolling bearing 2521a, and making the axial direction of the second rolling bearing 2521a parallel to the second bearing surface 2511 and perpendicular to the arrangement direction of the door body 210 and the sealing plate 220, the second rolling bearing 2521a can roll on the second bearing surface 2511 along the arrangement direction of the door body 210 and the sealing plate 220 during the floating process driven by the floating mechanism 230 to float. On the one hand, this makes the movement trajectory of the second rolling bearing 2521a parallel to the floating direction of the sealing plate 220, which helps to... Further reducing the frictional loss between the third support member 251 and the fourth support member 252 can reduce the risk of jamming when the sealing plate 220 floats, thereby effectively improving the smoothness of the floating of the sealing plate 220. On the other hand, the second rolling bearing 2521a can transfer part of the weight of the sealing plate 220 to the door body 210, which can reduce the risk of deformation or sinking of the sealing plate 220 during long-term floating, so that the sealing plate 220 can fit more tightly and stably with the edge of the opening 100b, which is beneficial to extending the service life of the door body 200.

[0090] In some embodiments, the second support assembly 250 further includes a first fixing rod 253, which is disposed on the side of the sealing plate 220 facing the door body 210 and extends axially along the second rolling bearing 2521a. A fourth support member 252 is disposed on the side of the first fixing rod 253 near the third support member 251.

[0091] The first fixing rod 253 extends axially along the second rolling bearing 2521a, that is, the extension direction of the first fixing rod 253 is perpendicular to the floating direction of the sealing plate 220.

[0092] The first fixing rod 253 can be fixed to the sealing plate 220 by means of welding, bolting, riveting, snap-fit ​​connection, etc.

[0093] The fourth support member 252 can be integrally formed on the first fixed rod 253; or it can be fixedly connected to the first fixed rod 253. The fixed connection method can be welding, bolting, riveting, snap-fit ​​connection, etc., but is not limited to these.

[0094] By setting the first fixing rod 253 on the side of the sealing plate 220 facing the door body 210, and extending the first fixing rod 253 along the axial direction of the second rolling bearing 2521a, the bending strength of the sealing plate 220 in the extension direction of the first fixing rod 253 can be enhanced, and the risk of deformation of the sealing plate 220 due to floating can be reduced.

[0095] The door body 200 may include multiple second support assemblies 250. The fourth support member 252 of each of the multiple second support assemblies 250 is disposed on the side of the first fixing rod 253 near the third support member 251, and the fourth support members 252 of the multiple second support assemblies 250 are sequentially spaced along the extension direction of the first fixing rod 253. The number of second support assemblies 250 can be two, three, five, six, eight, etc., but is not limited to these. The specific number of second support assemblies 250 can be selected according to the dimensions of the first fixing rod 253 along its extension direction. By setting multiple second support assemblies 250, not only can the smoothness of the floating of the sealing plate 220 be further improved, but the gravity of the sealing plate 220 can also be distributed along the axial direction of the second rolling bearing 2521a to multiple areas of the door body 210, reducing the risk of local stress concentration.

[0096] In some embodiments, referring to Figures 4 and 6, the floating mechanism 230 includes an elastic component 231. The elastic component 231 is connected between the door body 210 and the sealing plate 220. The elastic component 231 is used to provide a clamping force on the sealing plate 220 toward the housing 100 when the door body 200 is in the closed state.

[0097] During the closing process of the door 200, the side of the sealing plate 220 facing away from the door body 210 first contacts the edge of the opening 100b. As the door 200 continues to close, the edge of the opening 100b generates a pushing force toward the sealing plate 220, causing the elastic component 231 to contract and generate an elastic restoring force toward the cabinet 100. This elastic restoring force can be converted into a pressing force of the sealing plate 220 toward the cabinet 100, causing the sealing plate 220 to float toward the cabinet 100 and fit tightly against the edge of the opening 100b, effectively improving the effect of the door 200 on the baking cavity 100a. When the door 200 is in the closed state, the edge of the opening 100b provides a continuous pushing force to the sealing plate 220, keeping the elastic component 231 in a continuous compressed state, thus continuously providing a pressing force of the sealing plate 220 toward the cabinet 100.

[0098] During the opening of the door 200, the thrust of the edge of the opening 100b toward the sealing plate 220 disappears, the elastic component 231 recovers its elastic deformation as the thrust disappears, and drives the sealing plate 220 to float toward the door body 210.

[0099] By connecting the elastic component 231 between the door body 210 and the sealing plate 220, the elastic component 231 can provide a pressing force to the sealing plate 220 towards the box 100 when the door body 200 is in the closed state, so that the sealing plate 220 floats towards the box 100 and fits tightly against the edge of the opening 100b, which can effectively improve the effect of the door body 200 on the baking cavity 100a; in addition, the elastic component 231 can also automatically adjust the compression amount according to the flatness of the edge of the opening 100b, which can effectively improve the sealing strength between the sealing plate 220 and the edge of the opening 100b.

[0100] In some embodiments, referring to Figures 4 and 6, a receiving cavity 200a is formed between the door body 210 and the sealing plate 220. A floating mechanism 230 is disposed within the receiving cavity 200a. The door body 200 includes two side plates 240 disposed opposite to each other on both sides of the receiving cavity 200a. The floating mechanism 230 further includes a second fixing rod 232 connected between the two side plates 240, and an elastic component 231 disposed between the second fixing rod 232 and the sealing plate 220.

[0101] The two side plates 240 can be part of the door body 210; or the two side plates 240 can be structures independent of the door body 210, used to seal the receiving cavity 200a between the door body 210 and the sealing plate 220.

[0102] The extension direction of the second fixing rod 232 can be parallel to the extension direction of the first fixing rod 253, so that the first fixing rod 253 and the second fixing rod 232 do not interfere with each other structurally.

[0103] By connecting the second fixing rod 232 between the two side plates 240 and setting the elastic component 231 between the second fixing rod 232 and the sealing plate 220, the second fixing rod 232 can provide stable support for the elastic component 231 and transfer part of the elastic restoring force generated when the elastic component 231 contracts to the door body 210, thereby reducing the risk of damage to the elastic component 231 or uneven stress on the sealing plate 220 due to stress accumulation at the end of the elastic component 231 near the door body 210.

[0104] In some embodiments, referring to Figure 6, the elastic component 231 includes a positioning post 2311 and an elastic body 2312. One end of the positioning post 2311 is fixed to the side of the second fixing rod 232 facing the sealing plate 220, and the other end extends toward the sealing plate 220 and is spaced apart from the sealing plate 220. The elastic body 2312 is sleeved on the positioning post 2311, and one end of the elastic body 2312 abuts against the positioning post 2311 or the second fixing rod 232, and the other end abuts against the sealing plate 220.

[0105] The positioning post 2311 can be integrally formed on the side of the second fixing rod 232 facing the sealing plate 220; or it can be fixed to the side of the second fixing rod 232 facing the sealing plate 220 by a fixed connection. The fixed connection method can be welding, adhesive connection, etc., but is not limited to these.

[0106] In some embodiments, the positioning post 2311 may include a base and a positioning body. The base is fixed to the side of the second fixing rod 232 facing the sealing plate 220, and the positioning body extends from the side of the base facing the sealing plate 220 toward the sealing plate 220, with the end of the positioning body closer to the base and spaced apart from the sealing plate 220. Alternatively, the positioning post 2311 may consist only of the positioning body, with one end fixed to the side of the second fixing rod 232 facing the sealing plate 220, and the other end extending toward the sealing plate 220 and spaced apart from it.

[0107] If the positioning post 2311 includes a base and a positioning body, then one end of the elastic body 2312 abuts against the side of the base facing the sealing plate 220, and the other end abuts against the sealing plate 220. If the positioning post 2311 only includes the positioning body, then one end of the elastic body 2312 abuts against the second fixing rod 232, and the other end abuts against the sealing plate 220.

[0108] The elastic body 2312 can be a spring.

[0109] By setting a positioning post 2311 on the side of the second fixing rod 232 facing the sealing plate 220, and sleeved the elastic body 2312 on the positioning post 2311, the positioning post 2311 can guide the elastic body 2312, so that the elastic body 2312 can be compressed or reset along the arrangement direction of the sealing plate 220 and the door body 210. This reduces the risk of lateral displacement or twisting of the elastic body 2312 during compression or reset, thereby making the floating trajectory of the sealing plate 220 controllable during the closing of the door body 200. This not only improves the stability of the sealing plate 220 during the floating process, but also improves the sealing effect of the sealing plate 220. By setting the positioning post 2311 and the sealing plate 220 at intervals, the interval between the positioning post 2311 and the sealing plate 220 can provide contraction space for the elastic body 2312, thereby reducing the risk of the elastic body 2312 failing due to contraction.

[0110] In some embodiments, referring to Figure 4, the floating mechanism 230 includes a plurality of second fixing rods 232, which extend along a first direction XX and are spaced apart sequentially along a second direction YY. Each second fixing rod 232 is provided with a plurality of elastic components 231 between itself and the sealing plate 220, and these elastic components are spaced apart sequentially along the first direction XX. The second direction YY is parallel to the arrangement direction of the top and bottom of the housing 100 and perpendicular to the first direction XX.

[0111] The number of second fixing rods 232 can be two, three, five, seven, eight, etc., but is not limited to these. The number of elastic components 231 between each second fixing rod 232 and the sealing plate 220 can be two, four, five, six, eight, etc., but is not limited to these. The specific number of second fixing rods 232 and the specific number of elastic components 231 can be selected according to the size of the door body 200.

[0112] By setting multiple second fixing rods 232 extending along the first direction XX and spaced apart along the second direction YY, and setting multiple elastic components 231 between each second fixing rod 232 and the sealing plate 220, the multiple elastic components 231 are distributed at multiple positions between the sealing plate 220 and the door body 210. On the one hand, the multiple elastic components 231 can automatically adjust the compression force according to the force, which can further improve the sealing effect of the sealing plate 220 on the baking cavity 100a. On the other hand, when one elastic component 231 becomes fatigued or damaged, the remaining elastic components 231 can still maintain the pressing force of the sealing door towards the box body 100, so that the door body 200 has fault tolerance capability, which can reduce the risk of the baking cavity 100a leaking air because the sealing door cannot float towards the box body 100 during the operation of the baking equipment 1000. Furthermore, the multiple elastic components 231 can share the thrust of the box body 100 towards the door body 200, which can alleviate the fatigue aging rate of the elastic components 231 and help extend the service life of the door body 200.

[0113] In some embodiments, please continue to refer to Figures 4 and 6, the door body 200 further includes a limiting component 260, which is disposed between the door body 210 and the sealing plate 220, and at least a portion of the limiting component 260 extends to the side of the sealing plate 220 facing away from the door body 210.

[0114] The limiting component 260 can be integrally formed on the door body 210; or the limiting component 260 can be fixedly connected to the door body 210. The fixed connection method can be welding, riveting, bolting, snap-fit ​​connection, etc., but is not limited to these.

[0115] By extending at least a portion of the limiting component 260 to the side of the sealing plate 220 facing away from the door body 210, the limiting component 260 can limit the floating range of the sealing plate 220 when it floats toward the housing 100, thereby reducing the risk that the sealing plate 220 may tilt or misalign with the edge of the opening 100b due to excessive floating displacement toward the housing 100, and thus reducing the possibility of sealing failure of the sealing plate 220.

[0116] In some embodiments, the door 200 includes two limiting components 260. One of the two limiting components 260 is disposed on the side of the door body 210 near the top of the box 100, and the other is disposed on the side of the door body 210 near the bottom of the box 100. This is to limit the floating displacement of the sealing plate 220 toward the box 100 on both sides along the arrangement direction of the top and bottom of the box 100. This can effectively improve the overall floating uniformity of the sealing plate 220, thereby improving the sealing effect of the sealing plate 220 on the baking cavity 100a.

[0117] In some embodiments, a clearance groove 220a is formed on the side of the sealing plate 220 facing away from the door body 210. The limiting assembly 260 includes a fixing part 261 and a limiting body 262. The fixing part 261 is disposed on the door body 210. The limiting body 262 is disposed on the side of the fixing part 261 near the sealing plate 220 and extends at least partially into the clearance groove 220a. When the door 200 is in the open state, there is a gap between the limiting body 262 and the bottom wall of the clearance groove 220a.

[0118] When the door 200 is closed, the clearance groove 220a is located on the side of the sealing plate 220 closest to the housing 100. The bottom wall of the clearance groove 220a is the inner wall of the clearance groove 220a opposite to the housing 100.

[0119] By configuring the limiting component 260 to include a fixing part 261 and a limiting body 262, and by placing the fixing part 261 on the door body 210 and the limiting body 262 on the fixing part 261, the structural strength of the limiting body 262 can be improved, and the risk of the limiting body 262 deforming or breaking under the impact of the bottom wall of the avoidance groove 220a can be reduced.

[0120] By providing an clearance groove 220a on the side of the sealing plate 220 facing away from the door body 210, and extending the limiting body 262 of the limiting component 260 into the clearance groove 220a, and ensuring that there is a gap between the limiting body 262 and the bottom wall of the clearance groove 220a when the door body 200 is in the open state, the gap between the limiting body 262 and the clearance groove 220a can provide the sealing plate 220 with floating space toward the box body 100 during the closing process of the door body 200, so that the sealing plate 220 can float within the floating space defined by the limiting component 260.
