TECHNICAL FIELD

[0001] The present application relates to the technical field of sealing machines, in particular to a sealing machine. BACKGROUND

[0002] With the improvement of people's living quality today, sealing machines have gradually appeared in each household. In the related art, the bag opening of a vacuum bag filled with food is placed in a sealing machine, the vacuum bag is vacuumized, and then the user manually presses the lock button or the pressure relief button on both sides of the sealing machine to release the pressure in the sealing cavity of the sealing machine, so that the cover of the sealing machine can be opened, and the vacuum bag can be taken out. In the whole operation process, the user needs to manually complete the pressure relief operation with force, the operation is complicated, the automation degree of the sealing machine is low, and the use performance of the product is low. CONTENT OF THE UTILITY MODEL

[0003] The present application aims to at least solve one of the technical problems existing in the prior art or related art.

[0004] To this end, the present application provides a sealing machine.

[0005] Therefore, the present application provides a sealing machine, which comprises a first cover group, a first sealing chamber and a first matching part. The first sealing chamber is movably connected with the first cover, the first cover is provided with a sealing part, the first sealing chamber is provided with an air inlet, and the first sealing chamber can move relative to the first cover to switch between a first position and a second position. A second cover group is movably connected with the first cover group, and the second cover group comprises a second sealing chamber and a second matching part. At least one of the first matching part and the second matching part is a magnetic part. When the first cover group and the second cover group are in a closed state, the first matching part and the second matching part are magnetically attracted to drive the first sealing chamber to move to the first position. The first sealing chamber and the second sealing chamber enclose a vacuum chamber, and the air inlet abuts against the sealing part to block the air inlet. When the first cover group and the second cover group are in an open state and the vacuum chamber is in a vacuum state, the first matching part and the second matching part are separated, the second cover group drives the first sealing chamber to move from the first position to the second position, so that the air inlet is separated from the sealing part to open the air inlet.

[0006] The sealing machine provided by the present application comprises a first cover group and a second cover group. The second cover group is movably connected with the first cover group.

[0007] The first cover group comprises a first cover, a first sealing chamber and a first matching part. The second cover group comprises a second sealing chamber and a second matching part.

[0008] The first sealing bin is movably connected with the first cover body, and the first sealing bin is movable relative to the first cover body to switch between a first position and a second position. When the first sealing bin moves to the first position, the first sealing bin and the second sealing bin enclose a vacuum cavity, and the first matching part and the second matching part are magnetically attracted to each other. When the first sealing bin moves to the second position, the first sealing bin and the second sealing bin are separated, and the first matching part and the second matching part are separated.

[0009] When the vacuum bag is subjected to a vacuumizing operation, the bag opening of the vacuum bag is first placed in the first sealing bin or the second sealing bin, and then the first cover body set or the second cover body set is closed, so that the first cover body set and the second cover body set are in a closed state, the first matching part and the second matching part are magnetically attracted to each other, the second sealing bin and the first sealing bin enclose a vacuum cavity, and the second sealing bin presses the first sealing bin to drive the first sealing bin to move to the first position, so that the air inlet provided on the first sealing bin abuts against the sealing part provided on the first cover body to block the air inlet. At this time, the air in the environment cannot enter the vacuum cavity through the air inlet. The vacuum cavity is subjected to a vacuumizing operation, and the first sealing bin and the second sealing bin are attracted together by the air pressure. After the vacuumizing operation is completed, the first cover body set or the second cover body set is opened, the first matching part and the second matching part are separated and no longer provide a pressing force. The first sealing bin and the second sealing bin are attracted together by the air pressure, and the second sealing bin drives the first sealing bin to move from the first position to the second position. At this time, the air inlet provided on the first sealing bin is separated from the sealing part provided on the first cover body, and air flows into the vacuum cavity through the air inlet. The vacuum cavity is no longer in a sealed vacuum state, and the first sealing bin and the second sealing bin are no longer affected by the pressure difference. The first sealing bin and the second sealing bin are separated and fall off to complete the opening operation of the sealing machine.

[0010] Therefore, by reasonably arranging the structure of the sealing machine, the sealing machine has the function of automatic pressure relief, and the user does not need to manually operate the pressure relief. The operation of the sealing machine is time-saving, labor-saving and convenient. The use performance of the sealing machine is enriched, and the use performance and market competitiveness of the sealing machine are improved.

[0011] It can be understood that at least one of the first matching part and the second matching part is a magnetic part, that is, the first matching part is a magnetic part, or the second matching part is a magnetic part, or both the first matching part and the second matching part are magnetic parts.

[0012] When both the first matching part and the second matching part are magnetic parts, the first matching part and the second matching part are magnetically attracted to each other. For example, the first matching part includes any one or a combination of the following: a samarium-cobalt magnet, a ferrite magnet, a neodymium-iron-boron magnet, and an aluminum-nickel-cobalt magnet. The second matching part includes any one or a combination of the following: a samarium-cobalt magnet, a ferrite magnet, a neodymium-iron-boron magnet, and an aluminum-nickel-cobalt magnet.

[0013] When one of the first cooperating member and the second cooperating member is a magnetic member, the other is a metal member, the first cooperating member and the second cooperating member are magnetically attracted to each other, wherein the metal member comprises at least one of an iron member, a cobalt member and a nickel member.

[0014] According to the sealing machine provided in the application, the sealing machine can further have the following additional technical features.

[0015] In some technical solutions, the sealing machine further comprises a support part arranged on one of the first cover group and the second cover group, and the support part is used to support the first cover group and the second cover group.

[0016] In this technical solution, the structure of the sealing machine is further limited.

[0017] The sealing machine further comprises a support part arranged on one of the first cover group and the second cover group, that is, the support part is arranged on the first cover group or the support part is arranged on the second cover group.

[0018] The support part has the function of supporting the first cover group and the second cover group.

[0019] When the sealing machine is placed on a loading surface (such as a table top, a counter top and a cabinet top), the support part is in contact with the loading surface, and the support part supports the first cover group and the second cover group.

[0020] Exemplarily, the support part comprises a support leg, and the support leg can separate the first cover group and the second cover group from the loading surface.

[0021] Exemplarily, the support part comprises a support surface, and the support surface forms part of the outer surface of one of the first cover group and the second cover group. That is, the first cover group or the second cover group with the support surface is attached to the loading surface.

[0022] It can be understood that when the support part is arranged on the first cover group, the first cover group is closer to the loading surface than the second cover group.

[0023] It can be understood that when the support part is arranged on the second cover group, the second cover group is closer to the loading surface than the first cover group.

[0024] Exemplarily, when the first cover group and the second cover group are in the closed state, the support part is arranged on the first cover group, and the sealing machine is placed on the loading surface, the first cover group is located between the second cover group and the loading surface.

[0025] Exemplarily, when the first cover group and the second cover group are in the closed state, the support part is arranged on the second cover group, and the sealing machine is placed on the loading surface, the second cover group is located between the first cover group and the loading surface.

[0026] In some embodiments, when the support part is arranged in the first cover group and in the closed state, the first cover group further comprises an air inlet pipe arranged in the first sealing chamber, and one end of the air inlet pipe is connected to the air inlet.

[0027] In this embodiment, the structure of the first cover group is further defined.

[0028] The first cover group further comprises an air inlet pipe, and one end of the air inlet pipe is arranged in the first sealing chamber and connected to the air inlet.

[0029] When the first cover group and the second cover group are in the open state, air can enter the air inlet pipe through the air inlet, and then enter the vacuum cavity through the air inlet pipe.

[0030] It can be understood that the other end of the air inlet pipe has the function of guiding air to the vacuum cavity. The other end of the air inlet pipe has a height difference with the air inlet, so as to reduce the probability of juice flowing from the vacuum cavity to the air inlet through the air inlet pipe.

[0031] In some embodiments, when in the closed state, the other end of the air inlet pipe extends into the second sealing chamber.

[0032] In this embodiment, the cooperation structure of the first sealing chamber, the second sealing chamber and the air inlet pipe is further defined.

[0033] When the support part is arranged in the first cover group and in the closed state, the other end of the air inlet pipe extends into the second sealing chamber. Air flows to the vacuum cavity through the other end of the air inlet pipe. That is, the first cover group is located between the second cover group and the support part, and part of the juice has the possibility of accumulating in the first sealing chamber. Air flows into the vacuum cavity through the other end of the air inlet pipe, which raises the height of air entering the vacuum cavity. Therefore, even if the first sealing chamber accumulates juice, the juice will not enter the air inlet pipe through the other end of the air inlet pipe, which can avoid the situation that juice flows into the inside of the sealing machine through the air inlet. This structure provides support for the use performance of the sealing machine and is beneficial to prolong the service life of the sealing machine.

[0034] In some embodiments, the first cover group further comprises an elastic member, and the elastic member is located between the first sealing chamber and the first cover. The elastic member is used to drive the first sealing chamber to reset when the cover is opened.

[0035] In this embodiment, the structure of the first cover group is further defined.

[0036] The first cover group further comprises an elastic member. The elastic member is located between the first sealing chamber and the first cover.

[0037] When the first cover group and the second cover group are in the closed state, the first sealing bin extrudes the elastic member, so that the elastic member is in a compressed state. It can be understood that the magnetic attraction force of the first fitting member and the second fitting member is greater than the elastic force of the elastic member in the compressed state.

[0038] When the first cover group and the second cover group are in the open state, the first fitting member and the second fitting member are separated and no longer provide a pressing force. Because the first sealing bin and the second sealing bin are attracted together by air pressure, the second sealing bin will drive the first sealing bin to move from the first position to the second position, and at the same time, the elastic member will drive the first sealing bin to move from the first position to the second position, providing effective and reliable structural support for the movement of the first sealing bin to the second position.

[0039] In some technical solutions, optionally, the number of elastic members is a plurality, and the plurality of elastic members are arranged at intervals.

[0040] In this technical solution, the number of elastic members is further limited.

[0041] The number of elastic members is a plurality, and the plurality of elastic members are arranged at intervals. This setting increases the contact area and contact angle of the elastic member with the first cover and the first sealing bin, and can simultaneously drive the first sealing bin to move from multiple directions, so as to avoid the inclination of the first sealing bin and the situation that the first sealing bin is stuck in a certain place of the first cover, and provide structural support for the effective resetting of the first sealing bin to the second position.

[0042] In some technical solutions, optionally, the sealing machine further comprises a sealing structure for sealing the connection between the first sealing bin and the second sealing bin.

[0043] In this technical solution, the sealing machine further comprises a sealing structure, and when the first cover group and the second cover group are in the closed state, the sealing structure seals the connection between the first sealing bin and the second sealing bin, so as to ensure the sealing property of the vacuum cavity enclosed by the first sealing bin and the second sealing bin, avoid air leakage, and provide structural support for the sealing machine to effectively seal the bag opening of the vacuum bag.

[0044] The sealing structure includes sealing cotton, rubber members, plastic members, and the like, which are not listed one by one here.

[0045] In some technical solutions, optionally, the sealing structure comprises a first sealing ring arranged in the first sealing bin and surrounding the first sealing bin, and a second sealing ring arranged in the second sealing bin and surrounding the second sealing bin, and the first sealing ring and the second sealing ring abut when in the closed state.

[0046] In this technical solution, the sealing structure comprises a first sealing ring and a second sealing ring.

[0047] The first sealing ring is arranged in the first sealing chamber and surrounds the first sealing chamber. The second sealing ring is arranged in the second sealing chamber and surrounds the second sealing chamber. That is, the first sealing chamber serves as a mounting carrier of the first sealing ring and has the functions of mounting and fixing the first sealing ring. The second sealing chamber serves as a mounting carrier of the second sealing ring and has the functions of mounting and fixing the second sealing ring.

[0048] When the first cover group and the second cover group are in the closed state, under the magnetic attraction of the first matching part and the second matching part, the first sealing ring and the second sealing ring abut, and after the vacuum cavity is vacuumized, the first sealing ring and the second sealing ring are tightly attracted together to effectively seal the connection between the first sealing chamber and the second sealing chamber, avoiding the occurrence of air leakage.

[0049] In some technical solutions, optionally, the first cover comprises: a first shell; a first cover body connected with the first shell, the first shell and the first cover body enclosing a first mounting cavity, the first cover body being provided with an opening, the first mounting cavity being communicated with the opening, the first sealing chamber being movably arranged in the first mounting cavity, and the mouth wall of the opening being located at the peripheral side of the first sealing chamber; wherein the first matching part is arranged on the first shell or the first cover body, and the sealing part is arranged on the first shell.

[0050] In this technical solution, the first cover comprises the first shell and the first cover body. The first cover body is connected with the first shell. The first shell and the first cover body enclose the first mounting cavity, and the first sealing chamber is movably arranged in the first mounting cavity, that is, the first sealing chamber can move relative to the first mounting cavity to switch between the first position and the second position.

[0051] The first cover body is provided with an opening, the first mounting cavity is communicated with the opening, and the mouth wall of the opening is located at the peripheral side of the first sealing chamber. That is, part of the first sealing chamber is exposed to the first cover through the opening. This provides structural support for effective abutment of the first sealing chamber and the second sealing chamber. The first shell covers the outside of the first cover body and has the functions of protecting the first cover body and the first sealing chamber, which can ensure the appearance aesthetics of the first cover group.

[0052] Further, the first matching part is arranged on the first shell or the first cover body, that is, the first matching part is arranged on the first shell, or the first matching part is arranged on the first cover body. That is, one of the first shell and the first cover body serves as a mounting carrier of the first matching part and has the functions of mounting and fixing the first matching part.

[0053] Further, the sealing part is arranged on the first shell, that is, the first shell serves as a mounting carrier of the sealing part and has the functions of mounting and fixing the sealing part.

[0054] Exemplarily, the air inlet is located at the bottom of the first sealing chamber.

[0055] Exemplarily, the air inlet is located at a side of the first sealing chamber.

[0056] In some embodiments, the first cover body is provided with a stop plate configured to limit the displacement of the first sealing chamber in the second position.

[0057] In this embodiment, the first cover body is provided with a stop plate configured to limit the displacement of the first sealing chamber in the second position. When the first sealing chamber moves to the second position, the stop plate blocks the first sealing chamber, so that the first sealing chamber cannot continue to move relative to the first cover body, thereby ensuring the effective fit size of the first sealing chamber and the first cover body.

[0058] In some embodiments, the second cover body set further comprises a second housing, and a second cover body connected to the second housing, wherein the second sealing chamber is arranged in the second cover body, and the second fit component is arranged in the second housing or the second cover body.

[0059] In this embodiment, the second cover body set further comprises a second housing and a second cover body.

[0060] The second sealing chamber is arranged in the second cover body, i.e., the second cover body serves as a mounting carrier of the second sealing chamber, and has the function of mounting and fixing the second sealing chamber. The second housing covers the outer side of the second cover body, and has the function of protecting the second cover body and the second sealing chamber, thereby ensuring the aesthetic appearance of the second cover body set.

[0061] The second fit component is arranged in the second housing or the second cover body. The second fit component is arranged in the second housing, or the second fit component is arranged in the second cover body. That is, one of the second housing and the second cover body serves as a mounting carrier of the second fit component.

[0062] In some embodiments, the sealing machine further comprises a vacuum pump arranged in at least one of the first cover body set and the second cover body set, and a circuit board arranged in at least one of the first cover body set and the second cover body set, wherein the circuit board is electrically connected to the vacuum pump, and the circuit board controls the operation of the vacuum pump to control the vacuum pump to perform vacuumization on the vacuum cavity in the closed state.

[0063] In this embodiment, the sealing machine further comprises a vacuum pump and a circuit board, and the vacuum pump and the circuit board are electrically connected.

[0064] The vacuum pump is arranged in at least one of the first cover body set and the second cover body set. That is, the vacuum pump is arranged in the first cover body set. Alternatively, the vacuum pump is arranged in the second cover body set. Alternatively, the number of vacuum pumps is multiple, and a part of the multiple vacuum pumps are arranged in the first cover body set, and another part of the multiple vacuum pumps are arranged in the second cover body set.

[0065] The circuit board is arranged in at least one of the first cover group and the second cover group. That is, the circuit board is arranged in the first cover group. Alternatively, the circuit board is arranged in the second cover group. Alternatively, the number of the circuit boards is multiple, and a part of the circuit boards is arranged in the first cover group, and another part of the circuit boards is arranged in the second cover group.

[0066] The circuit board controls the vacuum pump to work to control the vacuum pump to pump the vacuum cavity to meet the use requirement of the sealing machine in the closed state.

[0067] In some technical solutions, the number of the first matching members and the second matching members is multiple, and each first matching member is matched with at least one second matching member; the number of the air inlets and the sealing members is multiple, and each air inlet is matched with at least one sealing member.

[0068] In the technical solution, the number of the first matching members is multiple, and the number of the second matching members is multiple. Each first matching member is matched with at least one second matching member. When the first cover group and the second cover group are in the closed state, each first matching member is magnetically attracted to at least one second matching member.

[0069] The arrangement increases the matching area of the first matching member and the second matching member, can improve the tightness of the first sealing cavity and the second sealing cavity, and is beneficial to improving the effectiveness and reliability of the first sealing cavity and the second sealing cavity to enclose the vacuum cavity.

[0070] In the technical solution, the number of the air inlets is multiple, and the number of the sealing members is multiple. Each air inlet is matched with at least one sealing member. When the first cover group and the second cover group are in the closed state, each air inlet is abutted to at least one sealing member to block the air inlet.

[0071] The arrangement increases the area of the air inlet, increases the gas entering the vacuum cavity through the air inlet per unit time when the first cover group and the second cover group are in the open state, and enables the first sealing cavity and the second sealing cavity to be quickly and effectively separated.

[0072] In some technical solutions, optionally, when the first cover group and the second cover group are in the closed state, the attractive force between the first matching member and the second matching member is F1, the elastic force of the elastic member is F2, and F1>F2.

[0073] In the technical solution, when the first cover group and the second cover group are in the closed state, the attractive force between the first matching member and the second matching member is F1, and the elastic force of the elastic member is F2. The relationship between F1 and F2 is limited to satisfy F1>F2, so that the second sealing cavity is tightly pressed together with the first sealing cavity.

[0074] When the sealing machine works, the first cover group or the second cover group is opened, the first matching part and the second matching part are separated and no longer provide the pressing force F1. The first sealing chamber and the second sealing chamber are attracted together by the vacuum, the second cover group is opened, the second cover group moves upward, the second sealing chamber moves upward together with the first sealing chamber, and the elastic force F2 of the elastic part also acts on the first sealing chamber to push the first sealing chamber to move upward. At this time, the air inlet on the first sealing chamber is separated from the sealing part, air enters through the air inlet at the bottom, the vacuum cavity is no longer in a sealed vacuum state, the first sealing chamber and the second sealing chamber are no longer subjected to the pressure, and the first sealing chamber resets under the action of the elastic part.

[0075] In some technical solutions, optionally, along the height direction of the sealing machine, the height of the air inlet pipe of the first cover group is greater than the height of the first sealing ring.

[0076] In this technical solution, the height relationship between the air inlet pipe and the first sealing ring is limited, so that along the height direction of the sealing machine, the height of the air inlet pipe of the first cover group is greater than the height of the first sealing ring. In this way, when the support part is arranged on the first cover group and is in the closed cover state, air flows into the vacuum cavity through the other end of the air inlet pipe. That is, the first cover group is located between the second cover group and the support part, and part of the juice has the possibility of accumulating in the first sealing chamber. Air flows into the vacuum cavity through the other end of the air inlet pipe, which raises the height of the air entering the vacuum cavity. In this way, even if the first sealing chamber accumulates juice, the juice will not enter the air inlet pipe through the other end of the air inlet pipe, and the situation of juice flowing into the sealing machine through the air inlet can be avoided. This provides structural support for ensuring the use performance of the sealing machine and is beneficial to prolong the service life of the sealing machine.

[0077] In some technical solutions, optionally, when the first cover group and the second cover group are in the open cover state, the distance from the air inlet to the sealing part along the height direction of the sealing machine is H2, and when switching from the open cover state to the closed cover state, the movement distance of the first sealing chamber in the height direction of the sealing machine is L1, and H2

[0078] In this technical solution, when the first cover group and the second cover group are in the open cover state, the distance from the air inlet to the sealing part along the height direction of the sealing machine is H2, and when switching from the open cover state to the closed cover state, the movement distance of the first sealing chamber in the height direction of the sealing machine is L1. The positional relationship between H2 and L1 is limited to satisfy H2 BRIEF DESCRIPTION OF DRAWINGS

[0097] When the first cover set 100 and the second cover set 200 are in a closed state, the first cooperating member 130 and the second cooperating member 220 are magnetically attracted to each other, driving the first sealing chamber 120 to move to the first position, the first sealing chamber 120 and the second sealing chamber 210 enclosing a vacuum cavity 300, and the air inlet 122 abutting against the sealing member 140 to block the air inlet 122.

[0098] When the first cover set 100 and the second cover set 200 are in an open state, and the vacuum cavity 300 is in a vacuum state, the first cooperating member 130 and the second cooperating member 220 are separated, and the second cover set 200 drives the first sealing chamber 120 to move from the first position to the second position, so that the air inlet 122 is separated from the sealing member 140 to open the air inlet 122.

[0099] A sealing machine 10 is provided, which includes a first cover set 100 and a second cover set 200. The second cover set 200 is openably and closably connected to the first cover set 100.

[0100] The first cover body set 100 comprises a first cover body 110, a first sealing bin 120 and a first matching piece 130. The second cover body set 200 comprises a second sealing bin 210 and a second matching piece 220.

[0101] The first sealing bin 120 is movably connected with the first cover body 110, and the first sealing bin 120 can move relative to the first cover body 110 to switch between a first position and a second position. When the first sealing bin 120 moves to the first position, the first sealing bin 120 and the second sealing bin 210 enclose the vacuum cavity 300, and the first matching piece 130 and the second matching piece 220 are magnetically attracted to each other. When the first sealing bin 120 moves to the second position, the first sealing bin 120 and the second sealing bin 210 are separated, and the first matching piece 130 and the second matching piece 220 are separated.

[0102] When the vacuum bag is subjected to the vacuumizing operation, the bag opening of the vacuum bag is first placed in the first sealing bin 120 or the second sealing bin 210, and then the first cover body set 100 or the second cover body set 200 is closed, so that the first cover body set 100 and the second cover body set 200 are in a closed state, the first matching piece 130 and the second matching piece 220 are magnetically attracted to each other, the second sealing bin 210 and the first sealing bin 120 are enclosed to form the vacuum cavity 300, and the second sealing bin 210 presses the first sealing bin 120 to drive the first sealing bin 120 to move to the first position, so that the air inlet 122 provided on the first sealing bin 120 abuts against the sealing piece 140 provided on the first cover body 110 to block the air inlet 122. At this time, the air in the environment cannot enter the vacuum cavity 300 through the air inlet 122. The vacuum cavity 300 is subjected to the vacuumizing operation, and the first sealing bin 120 and the second sealing bin 210 are attracted together by the air pressure. After the vacuumizing operation is completed, the first cover body set 100 or the second cover body set 200 is opened, and the first matching piece 130 and the second matching piece 220 are separated and no longer provide a pressing force. The first sealing bin 120 and the second sealing bin 210 are attracted together by the air pressure, and the second sealing bin 210 drives the first sealing bin 120 to move from the first position to the second position. At this time, the air inlet 122 provided on the first sealing bin 120 is separated from the sealing piece 140 provided on the first cover body 110, and the air flows into the vacuum cavity 300 through the air inlet 122. The vacuum cavity 300 is no longer in a sealed vacuum state, and the first sealing bin 120 and the second sealing bin 210 are no longer affected by the pressure difference, so that the first sealing bin 120 and the second sealing bin 210 are separated and fall off to complete the opening operation of the sealing machine 10.

[0103] Therefore, by reasonably arranging the structure of the sealing machine 10, the sealing machine 10 has the function of automatic pressure relief, and the user does not need to manually operate the pressure relief. The operation of the sealing machine 10 is time-saving, labor-saving and convenient, the use performance of the sealing machine 10 is enriched, and the use performance and market competitiveness of the sealing machine 10 are improved.

[0104] It can be understood that at least one of the first fitting member 130 and the second fitting member 220 is a magnetic member, that is, the first fitting member 130 is a magnetic member, or the second fitting member 220 is a magnetic member, or both the first fitting member 130 and the second fitting member 220 are magnetic members.

[0105] When both the first fitting member 130 and the second fitting member 220 are magnetic members, the first fitting member 130 and the second fitting member 220 are magnetically attracted to each other. Illustratively, the first fitting member 130 includes any one or a combination of the following: a samarium-cobalt magnet, a ferrite magnet, a neodymium-iron-boron magnet, and an alnico magnet. The second fitting member 220 includes any one or a combination of the following: a samarium-cobalt magnet, a ferrite magnet, a neodymium-iron-boron magnet, and an alnico magnet.

[0106] When one of the first fitting member 130 and the second fitting member 220 is a magnetic member, the other is a metal member, and the first fitting member 130 and the second fitting member 220 are magnetically attracted to each other, wherein the metal member includes at least one of an iron member, a cobalt member, and a nickel member.

[0107] The embodiment provides a sealing machine 10, in addition to the technical features of the above-mentioned embodiment, the embodiment further includes the following technical features, such as Figure 2 and Figure 5 As shown in the sealing machine 10 further includes a support portion 400.

[0108] The support portion 400 is arranged in one of the first cover group 100 and the second cover group 200.

[0109] The support portion 400 is used to support the first cover group 100 and the second cover group 200.

[0110] In this embodiment, the structure of the sealing machine 10 is further limited.

[0111] The sealing machine 10 further includes a support portion 400, and the support portion 400 is arranged in one of the first cover group 100 and the second cover group 200, that is, the support portion 400 is arranged in the first cover group 100, or the support portion 400 is arranged in the second cover group 200.

[0112] The support portion 400 has the effect of supporting the first cover group 100 and the second cover group 200.

[0113] When the sealing machine 10 is placed on a loading surface (such as a table top, a counter top, and a cabinet top), the support portion 400 is in contact with the loading surface, and the support portion 400 supports the first cover group 100 and the second cover group 200.

[0114] Illustratively, the support portion 400 includes a support leg, and the support leg can separate the first cover group 100 and the second cover group 200 from the loading surface.

[0115] Exemplarily, the support part 400 comprises a support surface which forms part of the outer surface of one of the first cover set 100 and the second cover set 200. That is, the first cover set 100 or the second cover set 200 which is provided with the support surface is attached to the object support surface.

[0116] It can be understood that when the support part 400 is provided in the first cover set 100, the first cover set 100 is closer to the object support surface than the second cover set 200.

[0117] It can be understood that when the support part 400 is provided in the second cover set 200, the second cover set 200 is closer to the object support surface than the first cover set 100.

[0118] Exemplarily, when the first cover set 100 and the second cover set 200 are in the closed state, the support part 400 is provided in the first cover set 100, and the sealing machine 10 is placed on the object support surface, the first cover set 100 is located between the second cover set 200 and the object support surface.

[0119] Exemplarily, when the first cover set 100 and the second cover set 200 are in the closed state, the support part 400 is provided in the second cover set 200, and the sealing machine 10 is placed on the object support surface, the second cover set 200 is located between the first cover set 100 and the object support surface.

[0120] The embodiment provides a sealing machine 10, in addition to the technical features of the above-mentioned embodiment, the embodiment further comprises the following technical features, such as Figure 4 As shown in the figure, when the support part 400 is provided in the first cover set 100 and in the closed state, the first cover set 100 further comprises an air inlet pipe 150.

[0121] The air inlet pipe 150 is provided in the first sealing chamber 120.

[0122] One end of the air inlet pipe 150 is connected to the air inlet 122.

[0123] In this embodiment, the structure of the first cover set 100 is further limited.

[0124] The first cover set 100 further comprises an air inlet pipe 150, the air inlet end is provided in the first sealing chamber 120, and one end of the air inlet 122 is connected to the air inlet 122.

[0125] When the first cover set 100 and the second cover set 200 are in the open state, air can enter the air inlet pipe 150 through the air inlet 122, and enter the vacuum cavity 300 through the air inlet pipe 150.

[0126] It can be understood that the other end of the air inlet pipe 150 has the function of guiding air to the vacuum cavity 300. The other end of the air inlet pipe 150 has a height difference with the air inlet 122, so as to reduce the probability of juice in the vacuum cavity 300 flowing to the air inlet 122 through the air inlet pipe 150.

[0127] The embodiment provides a sealing machine 10, in addition to the technical features of the above-mentioned embodiments, the embodiment further comprises the following technical features: when in the closed state, the other end of the air inlet pipe 150 extends into the second sealing chamber 210.

[0128] In this embodiment, the cooperation structure of the first sealing chamber 120, the second sealing chamber 210 and the air inlet pipe 150 is further limited.

[0129] When the support part 400 is arranged on the first cover group 100 and in the closed state, the other end of the air inlet pipe 150 extends into the second sealing chamber 210. Air flows to the vacuum cavity 300 through the other end of the air inlet pipe 150. That is, the first cover group 100 is located between the second cover group 200 and the support part 400, and part of the juice has the possibility of accumulating in the first sealing chamber 120. Air flows into the vacuum cavity 300 through the other end of the air inlet pipe 150, which raises the height of air entering the vacuum cavity 300. Therefore, even if the first sealing chamber 120 accumulates juice, the juice will not enter the air inlet pipe 150 through the other end of the air inlet pipe 150, which can avoid the situation that juice flows into the sealing machine 10 through the air inlet. It provides structural support for ensuring the use performance of the sealing machine 10, and is beneficial to prolong the service life of the sealing machine 10.

[0130] The embodiment provides a sealing machine 10, in addition to the technical features of the above-mentioned embodiments, the embodiment further comprises the following technical features: as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The first cover group 100 further comprises an elastic member 160.

[0131] The elastic member 160 is located between the first sealing chamber 120 and the first cover 110.

[0132] The elastic member 160 is used to drive the first sealing chamber 120 to reset in the open cover state.

[0133] In this embodiment, the structure of the first cover group 100 is further limited.

[0134] The first cover group 100 further comprises an elastic member 160. The elastic member 160 is located between the first sealing chamber 120 and the first cover 110.

[0135] When the first cover group 100 and the second cover group 200 are in the closed state, the first sealing chamber 120 presses the elastic member 160, so that the elastic member 160 is in a compressed state. It can be understood that the magnetic attraction force of the first fitting member 130 and the second fitting member 220 is greater than the elastic force of the elastic member 160 in the compressed state.

[0136] When the first cover group 100 and the second cover group 200 are in the open state, the first fitting member 130 and the second fitting member 220 are separated and no longer provide a pressing force. Because the first sealing chamber 120 and the second sealing chamber 210 are attracted together by air pressure, the second sealing chamber 210 drives the first sealing chamber 120 to move from the first position to the second position, and at the same time, the elastic member 160 drives the first sealing chamber 120 to move from the first position to the second position, thereby providing effective and reliable structural support for the movement of the first sealing chamber 120 to the second position.

[0137] Exemplarily, the elastic member 160 includes a spring.

[0138] The embodiment provides a sealing machine 10, in addition to the technical features of the above-mentioned embodiments, the embodiment further includes the following technical features: the number of elastic members 160 is multiple.

[0139] The multiple elastic members 160 are arranged at intervals.

[0140] In this embodiment, the number of elastic members 160 is further limited.

[0141] The number of elastic members 160 is multiple, and the multiple elastic members 160 are arranged at intervals. This setting increases the contact area and contact angle of the elastic member 160 with the first cover 110 and the first sealing chamber 120, and simultaneously drives the first sealing chamber 120 to move from multiple directions, so as to avoid the inclination of the first sealing chamber 120 and the situation that the first sealing chamber 120 is stuck in a certain place of the first cover 110, thereby providing structural support for the effective resetting of the first sealing chamber 120 to the second position.

[0142] The embodiment provides a sealing machine 10, in addition to the technical features of the above-mentioned embodiments, the embodiment further includes the following technical features: as shown in Figure 1 The sealing machine 10 further includes a sealing structure 500.

[0151] When in the closed state, the first sealing ring 510 and the second sealing ring 520 abut.

[0152] In this embodiment, the sealing structure 500 comprises a first sealing ring 510 and a second sealing ring 520.

[0192] In this embodiment, the number of the first matching members 130 is multiple, and the number of the second matching members 220 is multiple. Each first matching member 130 matches with at least one second matching member 220. When the first cover group 100 and the second cover group 200 are in the closed state, each first matching member 130 is magnetically attracted to at least one second matching member 220.

[0197] This arrangement increases the area of the air inlet 122, and when the first cover group 100 and the second cover group 200 are in the open state, it increases the amount of gas entering the vacuum chamber 300 per unit time via the air inlet 122, so that the first sealed chamber 120 and the second sealed chamber 210 can be quickly and effectively separated.

The second cover body 240 is provided with a plurality of second mounting positions, and each second mounting position is provided with a second matching member 220.

[0203] When the first cover group 100 and the second cover group 200 are in the closed state, the plurality of first matching members 130 and the plurality of second matching members 220 are magnetically attracted to provide a pressing force F1. As shown in Figure 5 , under the action of the pressing force F1, the first sealing chamber 120 moves downward by L1, and the air inlet 122 at the bottom of the first sealing chamber 120 also moves downward by L1, so that the air inlet 122 is blocked by the sealing member 140 at the bottom to seal the air inlet 122.

[0204] At the same time, the first sealing chamber 120 is provided with an elastic member 160 below, when the first sealing chamber 120 moves downward by L1, the elastic member 160 below the first sealing chamber 120 is in a compressed state, the elastic member 160 provides an elastic force F2, F1>F2, so that the second sealing chamber 210 and the first sealing chamber 120 are tightly pressed together.

[0205] The first sealing chamber 120 is provided with a first sealing ring 510 (such as sealing cotton), and the second sealing chamber 210 is provided with a second sealing ring 520 (such as sealing cotton), and the first sealing ring 510 and the second sealing ring 520 cooperate to prevent the first sealing chamber 120 and the second sealing chamber 210 from leaking air.

[0206] When the sealing machine 10 starts to vacuum, the vacuum cavity 300 enclosed by the first sealing chamber 120 and the second sealing chamber 210 forms a vacuum state, at this time, the first sealing chamber 120 and the second sealing chamber 210 are tightly attracted together under the action of air pressure.

[0207] When the sealing machine 10 finishes working, the first cover group 100 or the second cover group 200 is opened, the first matching part 130 and the second matching part 220 are separated and no longer provide the pressing force F. The first sealing chamber 120 and the second sealing chamber 210 are attracted together by the vacuum, the second cover group 200 is opened, so that the second cover group 200 moves upward by L2, the second sealing chamber 210 drives the first sealing chamber 120 to move upward together, at the same time, the elastic force F2 of the elastic part 160 also acts on the first sealing chamber 120, and pushes the first sealing chamber 120 to move upward by L3. At this time, the air inlet 122 on the first sealing chamber 120 is separated from the sealing part 140, air enters through the air inlet 122 at the bottom, the vacuum cavity 300 is no longer in a sealed vacuum state, the first sealing chamber 120 and the second sealing chamber 210 are no longer subjected to the pressure, and the first sealing chamber 120 is separated from the second sealing chamber 210. When L3 is greater than L1, the first sealing chamber 120 no longer moves because the baffle 115 of the first cover body 114 is limited in the first cover body 114, and the opening cover operation is completed.

[0208] The sealing machine 10 further comprises a supporting part 400, the supporting part 400 is arranged in one of the first cover group 100 and the second cover group 200, and the supporting part 400 is used for supporting the first cover group 100 and the second cover group 200. That is, when the sealing machine 10 is placed on a supporting surface, and the first cover group 100 and the second cover group 200 are in the closed state, the first cover group 100 is located between the supporting part 400 and the second cover group 200, or the second cover group 200 is located between the supporting part 400 and the first cover group 100.

[0209] Exemplarily, the air inlet 122 is located at the bottom of the first sealing chamber 120, or the air inlet 122 is located at the side of the first sealing chamber 120.

[0210] Exemplarily, the number of the first matching part 130 and the second matching part 220 is one.

[0211] Exemplarily, the number of the first matching part 130 and the second matching part 220 is multiple.

[0212] Exemplarily, the first matching part 130 is located at the opening 1142 of the first sealing chamber 120.

[0213] Exemplarily, the first matching part 130 is located in the first sealing chamber 120.

[0214] Exemplarily, the first matching part 130 is located on the first housing 112.

[0215] Exemplarily, the second matching part 220 is located on the second housing 230.

[0216] Exemplarily, the second fitting part 220 is located on the second cover body 240.

[0217] As shown in the figure, the first sealing bin 120 moves downward by L1 under the action of the pressing force F1 provided by the first fitting part 130 and the second fitting part 220. Figure 5

[0218] As shown in the figure, when the first cover body group 100 and the second cover body group 200 are in the open cover state, the distance from the air inlet 122 to the sealing part 140 is H2, and the distance from the bottom of the first sealing bin 120 to the inner bottom wall of the first cover body 110 is H1, wherein 0<H2<L1<H1. Figure 4

[0219] Exemplarily, the bottom of the first sealing bin 120 is provided with the air inlet 122, and the first sealing bin 120 is provided with the air inlet pipe 150, one end of the air inlet pipe 150 is connected with the air inlet 122, and the height of the air inlet pipe 150 is greater than the overall height of the first sealing bin 120 after the sealing cotton is installed. This setting can avoid that the accumulated water in the first sealing bin 120 flows to the inside of the sealing machine 10 through the air inlet pipe 150.

[0220] The first sealing bin 120 can move relative to the first cover body 110, the first sealing bin 120 can move upward to reset under the action of the elastic part 160, and the first sealing bin 120 can move downward and compress the elastic part 160 under the action of the pressure.

[0221] The elastic force of the elastic part 160 in the compressed state is greater than the vacuum pressure inside the vacuum cavity 300, which can reduce the cover opening resistance of the sealing machine 10 and reduce the cover opening difficulty of the sealing machine 10.

[0222] The embodiment provides a sealing machine 10, in addition to the technical features of the above-mentioned embodiment, the embodiment further includes the following technical features: when the first cover body group 100 and the second cover body group 200 are in the closed cover state, the attractive force between the first fitting part 130 and the second fitting part 220 is F1, and the elastic force of the elastic part 160 is F2, F1>F2.

[0223] In this technical scheme, when the first cover body group 100 and the second cover body group 200 are in the closed cover state, the attractive force between the first fitting part 130 and the second fitting part 220 is F1, and the elastic force of the elastic part 160 is F2. And limit the relationship between F1 and F2, so that F1>F2, so that the second sealing bin 210 and the first sealing bin 120 are tightly pressed together.

[0224] ​​When the sealing machine 10 finishes working, the first cover group 100 or the second cover group 200 is opened, the first matching part 130 and the second matching part 220 are separated and no longer provide the pressing force F1. The first sealing chamber 120 and the second sealing chamber 210 are attracted together by the vacuum, the second cover group 200 is opened, so that the second cover group 200 moves upward, the second sealing chamber 210 drives the first sealing chamber 120 to move upward together, at the same time, the elastic force F2 of the elastic part 160 also acts on the first sealing chamber 120, and pushes the first sealing chamber 120 to move upward. At this time, the air inlet 122 on the first sealing chamber 120 is separated from the sealing part 140, air enters through the air inlet 122 at the bottom, the vacuum cavity 300 is no longer in a sealed vacuum state, the first sealing chamber 120 and the second sealing chamber 210 are no longer subjected to the pressure, and the first sealing chamber 120 is reset under the action of the elastic part 160.

[0225] The embodiment provides a sealing machine 10, in addition to the technical features of the above-mentioned embodiment, the embodiment further includes the following technical features: the height of the air inlet pipe 150 of the first cover group 100 is greater than the height of the first sealing ring 510 in the height direction of the sealing machine 10.

[0226] In the technical scheme, the height relationship of the air inlet pipe 150 and the first sealing ring 510 is limited, so that the height of the air inlet pipe 150 of the first cover group 100 is greater than the height of the first sealing ring 510 in the height direction of the sealing machine 10. In this way, when the support part 400 is arranged on the first cover group 100 and is in the cover closing state, air flows to the vacuum cavity 300 through the other end of the air inlet pipe 150. That is, the first cover group 100 is located between the second cover group 200 and the support part 400, and part of the juice has the possibility of accumulating in the first sealing chamber 120. Air flows into the vacuum cavity 300 through the other end of the air inlet pipe 150, which raises the height of air entering the vacuum cavity 300. In this way, even if the juice is accumulated in the first sealing chamber 120, the juice will not enter the air inlet pipe 150 through the other end of the air inlet pipe 150, and the situation that the juice flows into the sealing machine 10 through the air inlet can be avoided. The structural support for ensuring the use performance of the sealing machine 10 is provided, and the service life of the sealing machine 10 is prolonged.

[0227] The embodiment provides a sealing machine 10, in addition to the technical features of the above-mentioned embodiment, the embodiment further includes the following technical features: as shown in Figure 4 and Figure 5 When the first cover group 100 and the second cover group 200 are in the cover opening state, the distance from the air inlet 122 to the sealing part 140 is H2 in the height direction of the sealing machine 10, when the cover opening state is switched to the cover closing state, the movement distance of the first sealing chamber 120 in the height direction of the sealing machine 10 is L1, and H2 < L1.

[0228] In the technical solution, when the first cover group 100 and the second cover group 200 are in the open cover state, the distance from the air inlet 122 to the sealing element 140 in the height direction of the sealing machine 10 is H2, when switching from the open cover state to the closed cover state, the movement distance of the first sealing chamber 120 in the height direction of the sealing machine 10 is L1. The positional relationship of H2 and L1 is limited to satisfy H2 < L1. That is, the movement distance of the first sealing chamber 120 in the height direction of the sealing machine 10 is greater than the distance from the air inlet 122 to the sealing element 140, so that the air inlet 122 and the sealing element 140 are elastically compressed and sealed, so that the air inlet 122 is effectively blocked by the sealing element 140, which can ensure the air tightness of the air inlet 122.
