Description

Technical Field

[0001] The utility model relates to the field of vacuum sealing machines, in particular to a multifunctional portable vacuum sealing machine. Background Art

[0002] The vacuum sealer puts food into a sealed bag and then extracts the air in the bag. The sealing process is completed when the predetermined vacuum degree is reached in the bag. The vacuuming is mainly completed through a vacuum chamber and a vacuum device. The bag mouth of the sealed bag is placed in the vacuum chamber, and the air in the vacuum chamber is extracted by the vacuum device to form a negative pressure, thereby sucking out the air in the sealed bag to form a vacuum state.

[0003] At present, vacuum sealers have a water collection container connected in series between the vacuum chamber and the vacuum device. The water collection container filters out the food juice that enters the airway with the airflow during vacuuming, which can prevent the air suction device from sucking in food juice and causing damage. At present, the water collection container of some vacuum sealers can be disassembled from the machine body, which is convenient for dumping the collected juice and rinsing and cleaning. However, there is also an airway built into the machine body between the water collection container and the vacuum chamber. The airway may have residual juice, which can cause bacteria to grow.

[0004] In addition, the vacuum device therein mainly includes a vacuum pump and a vacuum pipe. The air outlet of the vacuum pump is connected to the outside air, while the air inlet is connected to the vacuum chamber on the sealing machine through the vacuum pipe.

[0038] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0039] like Figures 1 to 16 As shown, a multifunctional portable vacuum sealer comprises a cover body 1 and a base body 2 that can be opened and closed, a sealing assembly 3 and a sealing ring 4 are arranged between the cover body 1 and the base body 2, and a vacuum chamber A is formed between the cover body 1 and the base body 2 through the sealing ring 4, a vacuum pump 5 and a main control board 6 for controlling the sealing assembly 3 and the vacuum pump 5 are arranged in the cover body 1, and the main control board 6 is electrically connected to a battery pack 10, a water receiving container 8 is detachably connected to the cover body 1, and the water receiving container 8 is connected to the air suction port 51 of the vacuum pump 5, and an air suction pipe 81 is arranged on the water receiving container 8, and the air suction pipe 81 directly leads to the vacuum chamber A;

[0040] This vacuum sealing machine can separate the exhaust pipe 81 from the cover body 1 together with the water receiving container 8, so as to facilitate the flushing and cleaning of the water receiving container 8 and the exhaust pipe 81, and has good hygiene. It can avoid the exhaust pipe 81 being fixedly installed in the cover body 1 or the base body 2, and the food juice sucked in during vacuuming will remain in the pipe for a long time, causing bacteria to grow.

[0041] It also includes an external air suction port 901, which is movably matched with the cover body 1, and a gas path conversion mechanism 9 is provided on the cover body 1 corresponding to the activity track of the external air suction port 901. When the external air suction port 901 is active, the state of the gas path conversion mechanism 9 is changed so that the external air suction port 901 is selectively connected to the suction port 51 of the vacuum pump 5;

[0042] In addition to conventionally evacuating the vacuum chamber A, this vacuum seal can also utilize the external vacuum port 901 to evacuate other vacuum packaging containers with a one-way exhaust interface 20, and the state of the gas path conversion mechanism 9 is changed by the action of the external vacuum port 901, so as to quickly switch between the vacuum chamber A and the external vacuum port 901.

[0043] The gas path conversion mechanism 9 includes a silicone valve seat 91 and a valve needle 92. The valve seat 91 is provided with a valve needle plug hole 911. One side of the valve needle plug hole 911 is provided with an opening 912 connected to the suction port 51 of the vacuum pump 5. The outer end of the valve needle 92 is connected to the external air extraction port 901. The inner end of the valve needle 92 is provided with a bypass port 921, which is plugged and matched with the valve needle plug hole 911. By rotating the valve needle 92, the bypass port 921 is connected or misaligned with the opening 912, so that the suction port 51 and the external air extraction port 901 are connected or disconnected.

[0044] This structure realizes the connection or isolation between the suction port 51 and the external air extraction port 901 by simple mechanical rotation of the valve needle 92. In more embodiments, the gas path conversion mechanism 9 can also be a reversing valve connecting the vacuum chamber A and the external air extraction port 901. The reversing valve is electrically connected to the gas path selection switch. The gas path selection switch is triggered by a starting structure such as a button, rotation, or mechanical structure, so that the reversing valve electronically switches the internal gas path, so that the suction port 51 of the vacuum pump 5 can be connected to the external air extraction port 901 or to the vacuum chamber A.

[0045] In addition, a positioning needle 913 extends into the valve needle insertion hole 911 , and the inner end of the valve needle 92 is inserted into the positioning needle 913 . The positioning needle 913 can ensure that the valve needle 92 can rotate coaxially, thus playing a supporting role.

[0046] The cover body 1 includes a shell 11, and the gas path conversion mechanism 9 also includes a gas path selection knob 93 rotatably connected to the shell 11, the valve needle 92 is coaxially connected to the inner end of the gas path selection knob 93, and the gas path selection knob 93 is provided with a suction interface 931 for docking with the exhaust interface 20 of the vacuumed object, and the external suction port 901 is opened on the gas path selection knob 93 along the axis and is connected with the suction interface 931; this structure can drive the valve needle 92 to rotate through the gas path selection knob 93 to achieve switching between connection and isolation, and also has an interface function, and when external suction is performed, it can dock with the exhaust interface 20 of other vacuumed objects.

[0047] A control switch 12 is also provided in the cover body 1, and the control switch 12 cooperates with the dynamic contact of the air circuit conversion mechanism 9. When the air circuit conversion mechanism 9 is connected to the external air suction port 901 and the suction port 51 of the vacuum pump 5, the control switch 12 cuts off the working circuit of the sealing component 3; the control switch 12 can be a mechanical micro switch, and a dynamic contact is provided on the valve needle 92 or the air circuit selection knob 93. When the valve needle 92 or the air circuit selection knob 93 is rotated to the connection position of the external air suction port 901, the dynamic contact touches the switch key of the micro switch, so that the heating and sealing operation cannot be performed during external air suction.

[0048] The water receiving container 8 is also provided with an exhaust pipe 82 connected to the inner cavity of the water receiving container 8, the suction port 51 of the vacuum pump 5 is connected to the exhaust pipe 82, and the shell 11 is provided with a first interface 101, the opening 912 is connected to the vacuum chamber A through the first interface 101, and the external exhaust port 901 is connected to the suction port 51 of the vacuum pump 5 through the air path conversion mechanism 9, the vacuum chamber A, and the inner cavity of the water receiving container 8 in sequence; this connection method can reduce the number of accessories inside the cover body 1, occupy less space, make the cover body 1 more compact and small, avoid the complicated layout of accessories, and have fewer exhaust pipes 81 connected during assembly, which can improve assembly efficiency.

[0049] The housing 11 is provided with a knob assembly port 103; the gas path conversion mechanism 9 further includes a knob connection seat 94 rotatably connected to the knob assembly port 103, the gas path selection knob 93 is fastened to the knob connection seat 94;

[0050] The side of the knob connecting seat 94 is connected to an arc-shaped elastic arm 941, and two positioning notches 942 are recessed on the elastic arm 941 at intervals. Two anti-rotation baffles 943 are extended from the elastic arm 941 and are respectively placed on the outer sides of the positioning notches 942. A positioning clamping plate 105 is extended from the shell 11 and is selectively matched with the two positioning notches 942 as the knob connecting seat 94 rotates. The positioning clamping plate 105 is placed between the two anti-rotation baffles 943.

[0051] In addition, a switch pressing plate 944 is extended from the inner side of the knob connecting seat 94 . The switch pressing plate 944 cooperates with the switch key of the control switch 12 (preferably a micro switch) when the knob connecting seat 94 rotates.

[0052] Two connecting bosses 932 extend from the gas path selection knob 93, and the two connecting bosses 932 are placed on the opposite sides of the valve needle 92; a rectangular groove 945 is stretched inwardly on the knob connecting seat 94, and the two connecting bosses 932 and the valve needle 92 are directionally inserted into the rectangular groove 945, and a through hole 946 is correspondingly provided at the bottom of the rectangular groove 945. The gas path selection knob 93 is assembled and connected to the knob connecting seat 94 by passing the through hole 946 and the connecting boss 932 through the fastening unit.

[0053] The gas path selection knob 93 is provided with a first stop position and a second stop position corresponding to the connection state and the isolation state of the external air extraction port 901. The gas path selection knob 93 is provided with an isolation mark 933 and a connection mark 934 corresponding to the first stop position and the second stop position, respectively. The shell 11 is provided with an indicator mark 112 corresponding to the connection mark 934 or the partition mark 933. In the present embodiment, the isolation mark 933 may be a similar word such as "sealed", the connection mark 934 may be a similar word such as "external extraction", and the indicator mark 112 may be a simple pattern with a "- " structure.

[0054] The use principle of the valve needle 92 and the gas path selection knob 93:

[0055] First, refer to Figure 5As shown, in the isolated state, the air path selection knob 93 is in the second anti-rotation position, and the corresponding positioning clamping plate 105 is clamped in one of the positioning notches 942 on the knob connecting seat 94. At this time, the anti-rotation baffle 943 corresponding to the positioning notch 942 restricts the knob connecting seat 94 from continuing to rotate toward one side thereof; correspondingly, the bypass port 921 of the valve needle 92 is misaligned with the opening 912 of the silicone valve seat 91, and the external air suction port 901 is isolated from the air suction port 51 of the vacuum pump 5. At this time, the vacuum sealing machine only performs vacuuming and sealing operations on the sealing bag.

[0056] When the isolation state is switched to the connection state, the user rotates the gas path selection knob 93, and the gas path selection knob 93 drives the knob connection seat 94 to rotate synchronously. In this process, the positioning card plate 105 presses against the elastic arm 941, compressing and deforming the elastic arm 941, and at the same time plays a damping role, until the gas path selection knob 93 is in the anti-rotation position 1, and the corresponding positioning card plate 105 is clamped in another positioning notch 942 of the knob connection seat 94, as shown in the figure, and the anti-rotation baffle 943 corresponding to the positioning notch 942 restricts the knob connection seat 94 from continuing to rotate (refer to Figure 6 As shown), correspondingly, the bypass port 921 of the valve needle 92 is opposite to the opening 912 of the silicone valve seat 91, and the external air suction port 901 is connected to the suction port 51 of the vacuum pump 5. At this time, the vacuum sealing machine can vacuum other vacuumed objects through the external air suction port 901.

[0057] The housing 11 includes a bottom shell 113 and an outer shell 114 assembled and connected to the bottom shell 113, an upper clamping plate 115 and a lower clamping plate 116 extend oppositely between the outer shell 114 and the bottom shell 113, a knob assembly opening 103 is formed between the upper clamping plate 115 and the lower clamping plate 116, and a convex ring shaft 947 rotatably connected to the knob assembly opening 103 extends from the knob connection seat 94;

[0058] Since the valve seat 91 is made of silicone material, the cooperation between the valve seat 91 and the valve needle 92 alone may easily cause pressure to cause the valve seat 91 to deform, resulting in air leakage between the valve needle 92 and the opening 912. Therefore, the knob assembly port 103 can not only act as a bearing, but also support the air path selection knob 93. The cooperation between the knob assembly port 103 and the convex ring shaft 947 can ensure that the air path selection knob 93 is coaxially connected to the knob assembly port 103, thereby reducing the stress of the valve needle 92 applied to the valve seat 91.

[0059] A valve seat mounting seat 1131 extends from the bottom shell 113, and the silicone valve seat 91 is fixed in the valve seat mounting seat 1131. A push column 1141 extends from the outer shell 114 corresponding to the valve seat mounting seat 1131, and the push column 1141 presses against the top of the silicone valve seat 91. During installation, the silicone valve seat 91 has been fixed in the valve seat mounting seat 1131 by interference fit, and the push column 1141 prevents the silicone valve seat 91 from shifting upward, thereby better fixing the silicone valve seat 91.

[0060] The gas path selection knob 93 is connected with a silicone sealing ring 17 along the outer peripheral edge of the air suction interface 931; in normal use, when the external air suction port 901 needs to evacuate other vacuumed objects, the air suction interface 931 can be sealed and docked at the exhaust interface 20 similar to the bottle mouth to perform vacuuming work. However, when the exhaust interface 20 has a small diameter and a short length and fails to form a sealing fit with the exhaust interface 20, the air suction interface 931 can be pressed against the vacuumed object, so that the silicone sealing ring 17 surrounds the outer periphery of the exhaust interface 20, so that a sealed cavity is formed between the air suction interface 931 and the vacuumed object, thereby realizing a vacuumized environment.

[0061] The air extraction pipe 81 includes an air extraction outer pipe section 811 and an air extraction inner pipe section 812. The air extraction inner pipe section 812 is placed in the water receiving container 8, and its upper end is close to the inner top surface of the water receiving container 8. The air extraction inner pipe section 812 with a certain height is helpful to separate air and juice, and the height of the air extraction inner pipe section 812 determines the maximum liquid storage capacity of the inner cavity of the water receiving container 8. Therefore, in the most ideal state, the closer the upper end of the air extraction inner pipe section 812 is to the inner top surface, the better. The increase in liquid storage capacity can reduce the number of times the water receiving container 8 is poured out, and extend the single use time of the vacuum sealer.

[0062] In other embodiments, the outer vacuum tube section 811 only needs to be inserted into the vacuum chamber A. This method is more effective in preventing juice from entering the vacuum air path. However, in this embodiment, the vacuum sealing machine needs to clean up the juice dripping into the vacuum chamber A while vacuuming. Therefore, the outer vacuum tube section 811 extends out of the water receiving container 8 along the disassembly and assembly direction and is inserted into the vacuum chamber A, and its lower end is arranged close to the bottom of the vacuum chamber A. The closer the outer vacuum tube section 811 is to the bottom of the chamber, the cleaner the juice in the vacuum chamber A is cleaned.

[0063] The water receiving container 8 is also provided with an exhaust pipe 82, and the exhaust pipe 82 includes an exhaust outer pipe section 821 and an exhaust inner pipe section 822. The exhaust inner pipe section 822 is placed in the water receiving container 8, and its upper end is closely arranged toward the inner top surface of the water receiving container 8 and is level or close to the height of the exhaust inner pipe section 812. The exhaust outer pipe section 821 extends out of the water receiving container 8 and is inserted into the cover body 1 to be connected with the suction port 51 of the vacuum pump 5. This structure can prevent the juice in the water receiving container 8 from being sucked into the exhaust pipe 82 and entering the vacuum pump 5.

[0064] The suction pipe 81 is arranged close to an inner wall of the water receiving container 8, and the exhaust pipe 82 is arranged close to the inner wall of the opposite side of the water receiving container 8; this structure allows the suction pipe 81 and the exhaust pipe 82 to be arranged as far apart as possible, thereby reducing the possibility that the suction pipe 81 sucks the liquid into the water receiving container 8 and splashes the liquid into the exhaust pipe 82;

[0065] In order to further avoid the above-mentioned problem, a water baffle 831 is extended from the inner top surface of the water receiving container 8, and the water baffle 831 is arranged between the inner air suction pipe section 812 and the inner air exhaust pipe section 822; in the present embodiment, the water baffle 831 is in an arc-shaped structure and is arranged close to the inner air suction pipe section 812, and is mainly arranged around the outer periphery of the inner air suction pipe section 812. The water baffle 831 can prevent the juice just sprayed into the water receiving container 8 by the inner air suction pipe section 812 from splashing into the inner air exhaust pipe section 822.

[0066] The water receiving container 8 comprises a water receiving box 83 with a box opening at the bottom and a box cover 84 detachably covered on the box opening, the air suction pipe 81 and the exhaust pipe 82 are integrally connected to the box cover 84; a water pouring port 841 is provided on the box cover 84, and a sealing cover 85 is detachably covered at the water pouring port 841, and the juice collected in the water receiving container 8 is poured out through the water pouring port 841. When cleaning, the box cover 84 is removed from the water receiving box 83, so that the inner walls of the water receiving box 83 and the box cover 84 and the tube cavities of the air suction pipe 81 and the exhaust pipe 82 can be better cleaned.

[0067] In addition, at least the water receiving box 83 of the water receiving container 8 is preferably made of transparent plastic material, so that the user can directly observe the liquid level in the water receiving container 8 during the vacuuming process, and can dump the accumulated liquid in the water receiving container 8 in time, eliminating the liquid level detection structure, and the operation is simple and direct.

[0068] A first sealing ring 18, a second sealing ring 19 and an exhaust interface 20 are clamped between the outer shell 114 and the bottom shell 113. The outer vacuum pipe section 811 passes through the first sealing ring 18 and is inserted into the vacuum chamber A. The outer exhaust pipe section 821 passes through the second sealing ring 19 and is connected to the air inlet end of the exhaust interface 20. The air outlet end of the exhaust interface 20 is connected to the suction port 51 of the vacuum pump 5.

[0069] The first sealing ring 18 plays a sealing role after the outer vacuum tube section 811 is inserted, so that the water receiving container 8 is immediately sealed during the insertion and assembly process, and the operation is simpler and more convenient; the outer vacuum tube section 811 is directly inserted into the vacuum chamber A through the first sealing ring 18, so that there is no need for excessive fixed pipelines between the vacuum chamber A and the water receiving container 8.

[0070] Similarly, after the exhaust outer pipe section 821 is inserted, the second sealing ring 19 can seal with the exhaust interface 20, and the exhaust interface 20 can act as an elbow, so that the cover body 1 can be reduced in size and more compact in shape.

[0071] The shell 114 is provided with a container installation cavity 117 with three open sides, the water receiving container 8 is detachably connected in the container installation cavity 117, and the surface of the water receiving container 8 smoothly transitions to the surface of the shell 114. The cooperation of the water receiving container 8 and the shell 114 in this structure can enhance the aesthetics of the vacuum sealer;

[0072] In addition, the shell 114 is provided with step surfaces 1171 corresponding to the three open openings, and the water receiving container 8 is extended with an outer flange 86 that abuts against the step surface 1171; among the above-mentioned three open openings, the top open opening is used for the disassembly and assembly entry of the water receiving container 8, and the open openings on both sides expose the side surfaces of the water receiving container 8, which is convenient for the user to observe the liquid level on the one hand, and convenient for the user to clamp the water receiving container 8 with his fingers for disassembly and assembly on the other hand, and there is no need to arrange handles, pulls and other structures on the water receiving container 8, thereby keeping the water receiving container 8 smooth and beautiful.

[0080] The decompression button 14 mainly includes a button base 14a and a button body 14b. The button base 14a is slidably connected to the guide seat 118. The avoidance cavity 141 is opened on the button base 14a, and the outer end of the button base 14a extends out of the shell 11 and is connected to the button body 14b. The user realizes the sliding of the decompression button 14 through the button body 14b, and the reset spring 21 automatically resets the decompression button 14 through its elastic potential energy to realize automatic locking.

[0081] The cover body 1 is connected with a limit pressure cover 22 placed above the decompression button 14, and the limit pressure cover 22 is provided with a guide clamping groove 221 corresponding to the avoidance cavity 141, which is suitable for the sliding vertical plate 151 to slide up and down, and a circular vertical guide groove 222 is provided on one side of the guide clamping groove 221, and the sliding vertical plate 151 is provided with a circular guide column 154 that linearly slides with the vertical guide groove 222;

[0082] The limit pressure cover 22 is actually covered on the guide seat 118, limiting the decompression button 14 from sliding back and forth between the guide seat 118 and the limit pressure cover 22, and the vertical guide groove 222 and the circular guide column 154 can ensure that the linkage part 15 can slide vertically, and the guide clamping groove 221 cooperates with the sliding vertical plate 151 to prevent the linkage part 15 from swinging left and right with the circular guide column 154 as the center.

[0083] In this embodiment, the upper connection portion includes an upper inverted block 143 integrally arranged on the side wall of the avoidance cavity 141, and a buckle inlet 1110 is opened on the bottom wall of the housing 11 corresponding to the avoidance cavity 141. The lower connection portion includes a buckle pin 144 fixed on the press-fit surface, and a lower inverted block 145 is provided on the top of the buckle pin 144 to be buckled and connected with the upper inverted block 143, and the opposite surfaces of the lower inverted block 145 and the upper inverted block 143 are both provided with an inclined introduction surface 146;

[0084] When the cover body 1 and the base body 2 are pressed together, the inclined guide surfaces 146 between them enable the upper inverted block 143 and the lower inverted block 145 to complete the buckling connection, and when the buckling pin 144 passes through the buckling entrance 1110 and extends into the avoidance cavity 141, its top pushes the linkage member 15 to move upward, the action is continuous and the operation is simple.

[0085] A main control board 6 is arranged on one side of the inner cavity of the shell 11, and the first switch 13 is a micro switch and is connected to the main control board 6; a decompression button 14 is connected to each of the left and right sides of the cover body 1, and a linkage member 15 is connected to the decompression button 14 corresponding to the micro switch; the upper inverted blocks 143 on the left and right decompression buttons 14 cooperate with the lower inverted blocks 145 arranged on the left and right, so that the cover body 1 can be smoothly pressed on the seat body 2, so that the force is more uniform.

[0086] The main control board 6 is also connected to a second switch 61 for turning on and off the working circuit of the vacuum pump 5. A through hole 1111 is provided on the shell 11 corresponding to the second switch 61. A vacuum valve 23 connected to the vacuum chamber A is installed on the through hole 1111. The vacuum valve 23 senses the pressure of the vacuum chamber A and triggers the second switch 61 through deformation. Only when the vacuum chamber A is in a vacuum state or a near vacuum state can the second switch 61 be triggered through the vacuum valve 23 to stop the vacuum pump 5, and then the sealing component 3 is started for sealing.

[0087] Specifically, the vacuum valve 23 includes a valve housing 231 and an elastic valve membrane 232. The elastic valve membrane 232 is connected to the opening of the valve housing 231 and encloses and defines an air pressure sensing chamber 233. The elastic valve membrane 232 covers the outside of the second switch 61 and elastically triggers the second switch 61. A limiting top column 234 extending toward the elastic valve membrane 232 is provided along the center of the bottom wall of the valve housing 231. The second switch 61 is also a micro switch.

[0088] The principle is that when the vacuum chamber A and the air pressure sensing chamber 233 are connected to each other, before vacuuming, the elastic valve membrane 232 is in the initial position and elastically presses against the switch key of the second switch 61, so that the main control board 6 determines that the vacuum chamber A is in a non-vacuum state. At this time, the working circuit of the sealing component 3 is disconnected, and the air pressure sensing chamber 233 forms a negative pressure with the vacuum chamber A. The elastic valve membrane 232 is sucked into the air pressure sensing chamber 233, and the elastic valve membrane 232 leaves the second switch 61. The switch key of the second switch 61 is reset, so that the main control board 6 determines that the vacuum chamber A is in a vacuum state before the working circuit of the sealing component 3 can be connected. The cooperation of the second switch 61 and the vacuum valve 23 can improve the safety of the sealing machine.

[0090] The bottom surface of the base body 2 is also connected with a magnet sheet 24; the vacuum sealer can be adsorbed on, for example, a refrigerator in the kitchen through the magnet sheet 24, which is convenient for users to use.

A sealing ring 4 is embedded in the lower sealing groove 202, and the sealing ring 4 is a raised structure with a high middle and low ends. In the prior art, the sealing ring 4 is relatively long and prone to bending. Therefore, in this embodiment, the middle of the lower sealing groove 202 is made higher. After the sealing ring 4 is embedded, the middle of the sealing ring 4 is slightly higher. When the cover body 1 and the seat body 2 are pressed together, it is ensured that the middle can be sealed and crimped with the upper sealing ring 4 first; after the two ends are moved upward by external force, they can also be sealed. After the lock tongue body and the press locker of the cover body cooperate, the seal is maintained in the best state.

[0093] In the present embodiment, an upper sealing groove 104 is provided on the joint surface of the cover body corresponding to the lower sealing groove 202, and a sealing ring 4 is embedded in the upper sealing groove 104. After the upper and lower sealing rings are abutted against each other, a vacuum chamber A is formed between the lower groove 201 and the cover body 1, and the sealing component 3 is arranged in the vacuum chamber A. The sealing component 3 built into the vacuum chamber can improve the sealing effect compared with being external to the vacuum chamber.

[0094] The sealing component 3 includes a long strip heating module 31 and a pressure contact strip 32, and the long strip heating module 31 and the pressure contact strip 32 are movably in contact with each other and are placed in the vacuum chamber A. The strip heating module 31 is connected to the cover body 1, and the pressure contact strip 32 is connected to the base body 2. In this embodiment, the long strip heating module 31 and the pressure contact strip 32 are built into the vacuum chamber A, and the sealing work is completed immediately after vacuuming.
