Description

Technical Field

[0001] This invention relates to vacuum devices and related vacuum articles, and more specifically, to a vacuum assembly suitable for containers and related vacuum articles. Background Technology

[0002] With technological advancements and economic development, an increasing number of consumer products are available on the market. For example, traditional vacuum systems typically include bags and vacuum devices. The bags can be used to hold food. The vacuum device can remove air from the bags to extend storage time and reduce storage volume. However, during the venting process, liquid inside the bags can easily leak out and enter the vacuum device, potentially causing damage. Summary of the Invention

[0003] The purpose of this invention is to provide a vacuum assembly suitable for containers and related vacuum products to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention discloses a vacuum assembly suitable for containers. The vacuum assembly includes a vacuum device and a liquid receiver. The liquid receiver is detachably mounted to the vacuum device and includes a receiving box, a seal, and a floating device. The receiving box includes an inlet and an outlet. The seal is located near the outlet of the receiving box. The floating device is movable relative to the receiving box between an initial position and a clamped position. The floating device includes a buoyancy component and a magnetic component. At least a portion of the buoyancy component is movably accommodated within the receiving box. The magnetic component is in contact with the buoyancy component and provides magnetic force when the vacuum device and the liquid receiver are mounted together. When the buoyancy device is in the initial position, the magnetic force does not drive the buoyancy device away from the initial position. After liquid flowing from the container drives the buoyancy device from the initial position to an actuated position between the initial position and the clamped position, the magnetic force drives the buoyancy device from the actuated position to the clamped position, whereby the buoyancy device clamps the seal with the receiving box to seal the outlet of the receiving box.

[0005] In one embodiment of the present invention, the receiving box further includes an upper box portion and a lower box portion detachably mounted to the upper box portion. The inlet is located in the lower box portion, and the outlet is located in the upper box portion.

[0006] In one embodiment of the invention, the liquid receiver further includes at least one auxiliary seal connected between the upper housing and the lower housing, and located between the vacuum device and the receiving box and / or between the receiving box and the container.

[0007] In one embodiment of the present invention, the vacuum device is provided with a first mating part, and the receiving box is provided with a second mating part, which mates with the first mating part to facilitate the installation of the vacuum device and the liquid receiver.

[0008] In one embodiment of the present invention, the buoyancy assembly includes a first buoyancy member and a second buoyancy member detachably mounted to the first buoyancy member. The second buoyancy member is disc-shaped. The first buoyancy member includes a main body portion and at least one extension portion extending from the main body portion and passing through the second buoyancy member.

[0009] In one embodiment of the present invention, the magnetic element is disposed between the first buoyancy element and the second buoyancy element, or at least a portion thereof is disposed within the first buoyancy element.

[0010] In one embodiment of the invention, the receiving box is provided with a guide portion that cooperates with the at least one extension portion to guide the buoyancy component.

[0011] In one embodiment of the present invention, the vacuum device includes a vacuum pump, a controller, and a pressure sensor; the controller is electrically connected to the vacuum pump. The pressure sensor is electrically connected to the controller to drive the controller to control the vacuum pump based on the detection result of the pressure sensor.

[0012] In one embodiment of the invention, the liquid receiver further includes at least one auxiliary seal connected between the vacuum device and the receiving box and / or between the receiving box and the container.

[0013] To achieve the above objectives, the present invention also discloses a vacuum article. The vacuum article includes a container and a vacuum assembly. The container includes a container body, a valve seat, and a one-way valve. The valve seat is disposed on the container body. The one-way valve is disposed on the valve seat. The vacuum assembly includes a vacuum device and a liquid receiver. The liquid receiver is detachably mounted to the vacuum device. The liquid receiver includes a receiving box, a seal, and a floating device. The receiving box includes an inlet and an outlet. The seal is located near the outlet of the receiving box. The floating device is movable relative to the receiving box between an initial position and a clamped position. The floating device includes a buoyancy component and a magnetic component. At least a portion of the buoyancy component is movably accommodated within the receiving box. The magnetic component is in contact with the buoyancy component, and provides magnetic force when the vacuum device and the liquid receiver are mounted together. When the buoyancy device is in the initial position, the magnetic force does not drive the buoyancy device away from the initial position. After the liquid flowing out of the container drives the buoyancy device from the initial position to an actuation position between the initial position and the clamping position, the magnetic force drives the buoyancy device from the actuation position to the clamping position, and the buoyancy device clamps the seal with the receiving box to seal the outlet of the receiving box.

[0014] In one embodiment of the present invention, the receiving box is provided with a first engaging portion, and the valve seat is provided with a second engaging portion, which cooperates with the first engaging portion to align the receiving box and the valve seat.

[0015] In one embodiment of the invention, the container further includes a filter element disposed on the valve seat and used to filter particles.

[0016] In one embodiment of the invention, the junction box further includes an upper box portion and a lower box portion detachably mounted to the upper box portion. The inlet is located in the lower box portion, and the outlet is located in the upper box portion.

[0017] In one embodiment of the invention, the liquid receiver further includes at least one auxiliary seal connected between the upper housing and the lower housing, and located between the vacuum device and the receiving box and / or between the receiving box and the valve seat of the container.

[0018] In one embodiment of the present invention, the vacuum device is provided with a first mating part, and the receiving box is provided with a second mating part, which mates with the first mating part to facilitate the installation of the vacuum device and the liquid receiver.

[0019] In one embodiment of the present invention, the buoyancy assembly includes a first buoyancy member and a second buoyancy member detachably mounted to the first buoyancy member. The second buoyancy member is disc-shaped. The first buoyancy member includes a main body portion and at least one extension portion extending from the main body portion and passing through the second buoyancy member.

[0020] In one embodiment of the present invention, the magnetic element is disposed between the first buoyancy element and the second buoyancy element, or at least a portion thereof is disposed within the first buoyancy element.

[0021] In one embodiment of the invention, the receiving box is provided with a guide portion that cooperates with the at least one extension portion to guide the buoyancy component.

[0022] In one embodiment of the invention, the vacuum device includes a vacuum pump, a controller, and a pressure sensor. The controller is electrically connected to the vacuum pump. The pressure sensor is electrically connected to the controller to drive the controller to control the vacuum pump based on the detection result of the pressure sensor.

[0023] In one embodiment of the invention, the liquid receiver further includes at least one auxiliary seal connected between the vacuum device and the receiving box and / or between the receiving box and the valve seat of the container.

[0024] In summary, the liquid receiver of the present invention uses the buoyancy device and the receiving box to clamp the sealing member, thereby sealing the outlet of the receiving box and preventing liquid flowing from the container from entering the vacuum device. Therefore, the present invention can effectively prevent liquid from damaging the vacuum device.

[0048] In the following detailed description of preferred embodiments, please refer to the accompanying drawings, which illustrate specific embodiments in which the invention can be implemented by way of illustration. Here, directional terms such as "up," "down," "left," "right," "front," "rear," etc., are used to describe the directional references in the drawings. Components of the invention can be arranged in multiple different directions. Therefore, directional terms are used for illustrative purposes and not for any limitation. Therefore, the drawings and descriptions should be considered illustrative and not restrictive.

[0049] Please see Figures 1 to 4 . Figure 1 This is a schematic diagram of the vacuum product 1A in the first embodiment of the present invention. Figure 2 This is an exploded view of the vacuum product 1A described in the first embodiment of the present invention. Figure 3 This is an exploded view of container 11A in the first embodiment of the present invention. Figure 4 This is a partial cross-sectional view of the container 11A described in the first embodiment of the present invention. Figures 1 to 4 As shown, the vacuum product 1A includes a container 11A and a vacuum assembly 12A. The container 11A includes a container body 111A, a valve seat 112A, and a one-way valve 113A. The container body 111A is used to contain food or any other object. The valve seat 112A is disposed on the container body 111A. The one-way valve 113A is located on the valve seat 112A. The vacuum assembly 12A expels air from the container body 111A. The one-way valve 113A allows air from the container body 111A to be extracted from the container 11A through the vacuum assembly 12A via the valve seat 112A and the one-way valve 113A, and prevents ambient air from entering the container body 111A via the valve seat 112A.

[0050] In this embodiment, the container body 111A and the one-way valve 113A can be a flexible sealing bag and a patch-type one-way valve 113A attached to the valve seat 112A, respectively. However, the present invention is not limited to this embodiment. For example, in another embodiment, the container body can be a rigid box or a rigid can, and the one-way valve can be a rubber umbrella valve. Alternatively, in another embodiment, the valve seat can be omitted, and the container body and the one-way valve can be a flexible sealing bag and a patch-type one-way valve attached to the container body, respectively.

[0051] Furthermore, such as Figure 4As shown, in this embodiment, the container 11A further includes a filter element 114A disposed on the valve seat 112A, which is configured to filter particles to prevent the one-way valve 113A from being damaged by the particles. Specifically, the filter element 114A may be made of a mesh fabric and installed onto the valve seat 112A by insert injection molding. However, the present invention is not limited to this embodiment. For example, in another embodiment, the filter element may be omitted.

[0052] Please refer to the following: Figures 5 to 10 . Figure 5 This is a schematic diagram of the vacuum component 12A when the vacuum device 121A and the liquid receiver 122A are separated in the first embodiment of the present invention. Figure 6 This is a diagram showing the internal structure of the vacuum assembly 12A when the vacuum device 121A and the liquid receiver 122A are separated in the first embodiment of the present invention. Figure 7 This is an exploded view of the vacuum component 12A described in the first embodiment of the present invention. Figure 8 This is a schematic diagram of the vacuum product 1A when the buoyancy device 1223A is in the initial position in the first embodiment of the present invention. Figure 9 This is a schematic diagram of the vacuum product 1A when the buoyancy device 1223A described in the first embodiment of the present invention is located in the clamping position K3A. Figure 10 This is a schematic block diagram of the vacuum device 121A described in the first embodiment of the present invention. Figures 5 to 10 As shown, the vacuum assembly 12A includes a vacuum device 121A and a liquid receiver 122A. The vacuum device 121A includes a vacuum pump 1211A for extracting air from the container body 111A from the container 11A, and a controller 1212A electrically connected to and used to control the vacuum pump 1211A. In this embodiment, the controller 1212A may be a control circuit board. However, the invention is not limited to this embodiment. The liquid receiver 122A is detachably mounted to the vacuum device 121A. The liquid receiver 122A includes a receiver box 1221A, a seal 1222A, and a buoyancy device 1223A. The receiver box 1221A is configured to be detachably connected to the valve seat 112A and includes an inlet P1A and an outlet P2A. The seal 1222A is located near the outlet P2A of the receiver box 1221A. The buoyancy device 1223A is positioned relative to the receiver box 1221A. Figure 8 The initial position K1A shown is Figure 9The device moves between the clamping positions K3A shown. The buoyancy device 1223 includes a buoyancy component 12231A and a magnetic element 12232A. At least a portion of the buoyancy component 12231A is movably disposed within the receiving box 1221A. The magnetic element 12232A is in contact with the buoyancy component 12231A. The magnetic element 12232A cooperates with a magnetic attraction element 1213A on the vacuum device 121A, thereby generating magnetic attraction; for example, when the vacuum device 121A is assembled with the liquid receiver 122A, the magnetic element 12232A provides magnetic attraction. The buoyancy device 1223A can be moved by liquid flowing from the container 11A and / or by magnetic attraction. Figure 8 As shown, when the buoyancy device 1223A is in the initial position K1A, for example, when no liquid flows out of the container 11A, the distance between the magnetic component 12232A and the magnetic attraction component 1213A on the vacuum device 121A is too large, resulting in insufficient magnetic force to overcome gravity, preventing the buoyancy device 1223A from leaving the initial position K1A by magnetic attraction. During the venting process, the liquid flowing out of the container 11A causes the buoyancy device 1223A to leave the initial position K1A. Figure 9 As shown, the liquid flowing out of the container 11A drives the buoyancy device 1223A from the initial position K1A to the actuated position K2A between the initial position K1A and the clamping position K3A. Because the distance between the magnetic component 12232A and the magnetic component 1213A on the vacuum device 121A decreases, a magnetic force sufficient to overcome gravity is generated. This causes the buoyancy device 1223A to move from the actuated position K2A to the clamping position K3A under the magnetic attraction. The buoyancy device 1223A clamps the sealing component 1222A with the receiving box 1221A to seal the outlet P2A of the receiving box 1221A. This arrangement effectively prevents the liquid flowing out of the container 11A from overflowing from the liquid receiver 122 into the vacuum device 121A, thereby preventing damage to the vacuum device 121A.

[0053] It should be noted that after the vacuum device 121A is separated from the liquid receiver 122A, the buoyancy device 1223A can be driven by gravity to move to the actuation position K2A away from the clamping position K3A, thereby opening the outlet P2A of the receiver box 1221A.

[0054] In this embodiment, the magnetic component 12232A and the magnetic attraction component 1213A can be two permanent magnets. However, the present invention is not limited to this embodiment. For example, in another embodiment, the magnetic component and the magnetic attraction component can be a permanent magnet and a ferromagnetic component, respectively.

[0055] like Figures 2 to 4 as well as Figures 6 to 9 As shown, to facilitate the installation of the receiving box 1221A and the valve seat 112A, a first engaging portion M1A is provided on the receiving box 1221A, and a second engaging portion M2A is provided on the valve seat 112A, which connects with the first engaging portion M1A, aligning the receiving box 1221A and the valve seat 112A. In this embodiment, the first engaging portion M1A can be a paired recessed structure, and the second engaging portion M2A can be a paired protruding structure inserted into the first engaging portion M1A. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first engaging portion and the second engaging portion can be a paired protruding structure and a paired recessed structure, respectively.

[0056] like Figures 5 to 9 As shown, to facilitate the assembly of the vacuum device 121A and the liquid receiver 122A, a first mating part C1A is provided on the vacuum device 121A, and a second mating part C2A is provided on the receiver 1221A, which mates with the first mating part C1A. In this embodiment, the first mating part C1A can be a paired recessed structure, and the second mating part C2A can be a paired protruding structure inserted into the first mating part C1A. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first mating part and the second mating part can be a paired protruding structure and a paired recessed structure, respectively.

[0057] Furthermore, such as Figures 6 to 9As shown, the receiving box 1221A has a first receiving space S1A and a second receiving space S2A. The inlet P1A communicates with the first receiving space S1A, and the outlet P2A communicates between the first receiving space S1A and the second receiving space S2A. Liquid flowing out of the container 11A can flow into the first receiving space S1A through the inlet P1A, and when the outlet P2A is not sealed, it can flow into the second receiving space S2A through the outlet P2A. The sealing member 1222A is disposed on the wall of the receiving box 1221A and is in contact with the first receiving space S1A. The buoyancy assembly 12231A includes a first buoyancy member B1A and a second buoyancy member B2A detachably installed to the first buoyancy assembly B1A. The second buoyancy member B2A is disc-shaped and is housed in the second receiving space S2A. The first buoyancy member B1A includes a main body B11A and an extension B12A extending from the main body B11A and passing through the second buoyancy member B2A. The first accommodating space S1A accommodates the main body portion B11A and is configured to connect with the sealing member 1222A. In other words, the main body portion B11A is located in the second buoyancy member B2A on the side near the inlet P1A of the receiving box 1221A, and the extension portion B12A extends from the main body portion B11A in a direction away from the inlet P1A of the receiving box 1221A. At least a portion of the magnetic member 12232A is disposed within the distal end of the extension portion B12A of the first buoyancy member B1A away from the main body portion B11A.

[0058] In this embodiment, the second buoyancy member B2A may be made of foam material, such that the buoyancy device 1223A moves from the initial position K1A through the actuation position k2a to the clamping position K3A before the liquid overflows from the second receiving space S2A, thereby sealing the outlet P2A. However, the invention is not limited to this embodiment. For example, in another embodiment, the second buoyancy member may be a plastic float.

[0059] Preferably, such as Figures 6 to 9As shown, the liquid receiver 122A further includes a first auxiliary seal 1224A and a second auxiliary seal 1225A. The first auxiliary seal 1224A is disposed on the receiving box 1221A and connected between the vacuum device 121A and the receiving box 1221A to prevent leakage from the gap between the vacuum device 121A and the receiving box 1221A. The second auxiliary seal 1225A is disposed on the receiving box 1221A and connected between the receiving box 1221A and the valve seat 112A of the container 11A to prevent leakage from the gap between the receiving box 1221A and the valve seat 112A of the container 11A. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first auxiliary seal may be disposed on the vacuum device, and the second auxiliary seal may be disposed on the valve seat. Alternatively, in another embodiment, at least one of the first and second auxiliary seals may be omitted.

[0060] In addition, such as Figures 7 to 10 As shown, in this embodiment, the vacuum device 121A further includes a pressure sensor 1214A. The pressure sensor 1214A is electrically connected to the controller 1212A and is used to sense the suction end pressure of the vacuum pump 1211A. When the buoyancy device 1223A is in the clamping position K3A, for example, when the seal 1222A is clamped by the buoyancy device 1223A and the receiving box 1221A, the suction end pressure of the vacuum pump 1211A drops rapidly. When the pressure sensor 1214A detects that the suction end pressure of the vacuum pump 1211A reaches a predetermined low pressure, the controller 1212A can stop the vacuum pump 1211A to prevent the vacuum device 121A from overloading. However, the present invention is not limited to this embodiment. For example, in another embodiment, the pressure sensor may be omitted.

[0061] Please see Figures 11 to 14 . Figure 11 This is a diagram showing the internal structure of the vacuum component 12B in the second embodiment of the present invention. Figure 12 This is an exploded view of the vacuum component 12B described in the second embodiment of the present invention. Figure 13 This is a schematic diagram of the vacuum component 12B when the buoyancy device 1223B is located at the initial position K1B in the second embodiment of the present invention. Figure 14 This is a schematic diagram of the vacuum component 12B when the buoyancy device 1223B is in the clamping position K3B according to the second embodiment of the present invention. Figures 11 to 14As shown, the vacuum assembly 12B can be applied to containers similar to 11A in the first embodiment. The vacuum assembly 12B includes a vacuum device 121B and a liquid receiver 122B detachably mounted to the vacuum device 121B. The liquid receiver 122B includes a receiving box 1221B, a sealing element 1222B, and the buoyancy device 1223B. The receiving box 1221B includes an upper box portion 12211B and a lower box portion 12212B detachably mounted to the upper box portion 12211B. A first mating portion C1B is provided on the vacuum device 121B, and a second mating portion C2B is provided on the upper box portion 12211B of the receiving box 1221B, which mates with the first mating portion C1B to facilitate the installation of the vacuum device 121B and the liquid receiver 122B. The first mating portion C1B and the second mating portion C2B can be a paired recessed structure and a paired protruding structure, respectively. A first engaging portion M1B is provided on the lower box portion 12212B of the receiving box 1221B, which is configured to cooperate with a second engaging portion located on the valve seat of the container, so that the receiving box 1221B is aligned with the valve seat of the container. An inlet P1B of the receiving box 1221B is provided on the lower box portion 12212B, and an inlet P2B of the receiving box 1221B is provided on the upper box portion 12211B. A sealing member 1222B is provided on the wall of the upper box portion 12211B of the receiving box 1221B, near the outlet P2B of the receiving box 1221B. The buoyancy device 1223B is located relative to the receiving box 1221B via... Figure 14 The actuation position K2B shown is in Figure 13 The initial position K1B shown is... Figure 14 The buoyancy device 1223B moves between the clamping positions K3B shown. When the buoyancy device 1223B is located as shown... Figure 14 When the clamping position K3B is shown, the seal 1222B is clamped by the buoyancy device 1223B and the receiving box 1221B to seal the outlet P2B of the receiving box 1221B.

[0062] The buoyancy device 1223B includes a buoyancy component 12231B and a magnetic component 12232B. The buoyancy component 12231B is movably accommodated in a receiving space SB defined by the upper box portion 12211B and the lower box portion 12212B of the receiving box 1221B. The buoyancy component 12231B includes a first buoyancy component B1B and a second buoyancy component B2B detachably mounted on the first buoyancy component B1B. The second buoyancy component B2B is disc-shaped, and the first buoyancy component B1B includes a main body portion B11B and an extension portion B12B. The main body portion B11B of the first buoyancy component B1B is located on the side of the second buoyancy component B2B away from the inlet P1B of the receiving box 1221B, so as to connect with the sealing component 1222B. An extension B12B of the first buoyancy member B1B extends from the main body B11B of the first buoyancy member B1B toward the inlet P1B of the receiving box 1221B and passes through the second buoyancy member B2B. The magnetic member 12232B is connected to the first buoyancy member B1B and at least a portion is disposed within the proximal end of the extension B12B of the first buoyancy member B1B near the main body B11B of the first buoyancy member B1B, to cooperate with the magnetic attraction member 1213B on the vacuum device 121B. A guide GB is provided on the lower box portion 12212B of the receiving box 1221B, which is configured to cooperate with the extension B12B to guide the buoyancy assembly 12231B back to the initial position K1B. The guide GB may be defined by a plurality of vertical walls WB located on the lower box portion 12212B.

[0063] The liquid receiver 122B further includes a first auxiliary seal 1224B, a second auxiliary seal 1225B, and a third auxiliary seal 1226B. The first auxiliary seal 1224B is disposed on the receiving box 1221B and connected between the vacuum device 121B and the receiving box 1221B to prevent leakage from the gap between the vacuum device 121B and the receiving box 1221B. The second auxiliary seal 1225B is disposed on the receiving box 1221B and connected between the receiving box 1221B and the valve seat of the container to prevent leakage from the gap between the receiving box 1221B and the valve seat of the container. The third auxiliary seal 1226B is disposed on the upper box portion 12211B and connected between the upper box portion 12211B and the lower box portion 12212B of the receiving box 1221B of the container, to prevent leakage from the gap between the upper box portion 12211B and the lower box portion 12212B of the receiving box 1221B.

Figure 20 When the clamping position K3D is shown, the seal 1222D is clamped by the buoyancy device 1223D and the receiving box 1221D to seal the outlet P2D of the receiving box 1221D.

The buoyancy component 12231D is movably accommodated within a receiving space SD defined by the upper box portion 12211D and the lower box portion 12212D of the receiving box 1221D.

The main body portion B11D of the first buoyancy member B1D is located on the side of the second buoyancy member B2D away from the inlet P1D of the receiving box 1221D and close to the sealing member 1222D. Two extensions B12D of the first buoyancy member B1D extend from the main body B11D of the first buoyancy member B1D toward the inlet P1D of the receiving box 1221D and pass through the second buoyancy member B2D. The magnetic member 12232D connects the main bodies B11D of the first buoyancy member B1D and the second buoyancy member B2D to cooperate with the magnetic attraction member 1213D on the vacuum device 121D.
