Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, specifically a new type of household multi-purpose sealing machine. Background Technology

[0002] A sealing machine is a machine that seals containers after they have been filled with products. Home cooking is no longer limited to "cooking and eating immediately," but has seen new scenarios such as "pre-prepared food storage," "leftover food repackaging," "resealing of takeout containers," and "portioned food preservation." For example, working people may prepare lunches a week in advance and need to seal the containers to prevent cross-contamination of odors; leftovers from family meals, if simply covered with plastic wrap, are prone to spoilage due to insufficient sealing, while a sealing machine can achieve a tight seal, extending the shelf life.

[0003] Existing sealing machines have limited functionality and are mostly inconvenient to select vacuum sealing or sealing of food containers as needed, making them impractical. Furthermore, most existing vacuum sealing machines require manual pressing of the top cover during use, which leads to inconvenience in operation.

[0004] To address the aforementioned issues, a novel multi-purpose household sealing machine is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel household multi-purpose sealing machine includes a body, an installation groove is provided at the lower front end of the body, a sealing base is fixedly connected in the installation groove, a vacuum chamber is provided at the top center of the sealing base, a cavity is provided at the upper interior of the front end of the body, limit posts are fixedly connected to both sides of the lower interior of the cavity, and the limit posts are located on both sides of the installation groove, a limit protrusion is fixedly connected to the lower exterior of the limit posts, an airbag cover is fixedly connected between the tops of the limit posts, an airbag is fixedly connected to the bottom of the airbag cover, an airbag sealing plate is fixedly connected to the bottom of the airbag, a vacuum groove is provided at the center of the bottom of the airbag sealing plate, and a vacuum groove is provided on the outer ring of the vacuum groove. The upper sealing silicone is used. A heating wire support silicone is fixedly connected to the bottom front end of the airbag sealing plate. A first heating wire is fixedly connected to the bottom of the heating wire support silicone. An air pump is fixedly connected to the right side of the body. An air pump is set at the front end of the air pump and is fixedly connected to the inner wall of the body. A food container slot is opened on the top of the body. A top cover is rotatably connected to the rear end of the top of the body. A latch is set on the outside of the top cover. A heating sealing assembly is installed on the inside of the top cover. A latch is set on the outside of the top cover. Sliding grooves are opened on both sides of the sealing base. A water collection tank buckle is fixedly connected to the rear end of the sealing base. A card seat slider is fixedly connected to both sides of the mounting groove. A water collection tank latch is fixedly connected to the rear end of the mounting groove.

[0007] By adopting the above technical solution, the airbag's inflating and deflating allows for the up-and-down movement of the airbag sealing plate. The airbag sealing plate also ensures close contact between the first heating wire mounted on it and the silicone pressure bag installed in the mounting groove, guaranteeing a heat-sealing effect. When the airbag inflates, it ensures effective vacuum sealing, eliminating the need for manual pressing and making the process more convenient.

[0008] As a further description of the above technical solution: the heating sealing assembly includes a through groove, which is disposed inside the top cover and communicates with the interior of the top cover. A heating wire frame is disposed inside the through groove. A second heating wire is fixedly connected to the outside of the heating wire frame. A connector is fixedly connected to the outer ring of the heating wire frame. A limit rod is slidably connected through the connector. A second spring is sleeved on the outer ring of the limit rod. The second spring is disposed between the connector and the interior of the top cover. A fixing sheet metal is fixedly connected between the ends of the two limit rods. A second airbag is fixedly connected to the outside of the fixing sheet metal. An ultraviolet lamp plate is fixedly connected to the middle of the inner side of the heating wire frame.

[0009] By adopting the above technical solution, the heating wire holder can be moved up and down by controlling the inflation and deflation of the second airbag. The airbag is connected to the output end of the air pump and the solenoid valve through an air tube. When the lunch box needs to be heated, the air pump is activated, and the output end blows out gas, causing the airbag to inflate and push the heating wire holder downward, so that it makes close contact with the lunch box support silicone on the machine body, ensuring the heating effect of the sealed lunch box.

[0010] As a further description of the above technical solution: the outer ring of the vacuum chamber is provided with a lower sealing silicone, and the lower sealing silicone is fixedly connected to the sealing base.

[0011] By adopting the above technical solution, a groove is opened on the top of the sealing base outside the vacuum chamber, and the lower sealing silicone is installed in the groove.

[0017] By adopting the above technical solution, when the double-way solenoid valve is not working, both ends are sealed, so that the air bladder end and the vacuum chamber end do not interfere with each other. When the double-way solenoid valve is energized, the two air pipes are interconnected, so that the air bladder end and the vacuum chamber end are connected, and the negative pressure and positive pressure at both ends cancel each other out, and both return to atmospheric pressure.

[0018] As a further description of the above technical solution: a sealing clip is provided on the outside of the food container slot, and the sealing clip is fixedly connected to the machine body.

[0019] By adopting the above technical solution, the sealing film covering the lunch box can be easily fixed by the sealing clip.

[0020] As a further description of the above technical solution: the top front end of the sealing base is provided with a placement groove, and a bag-pressing silicone is fixedly connected in the placement groove, and the bag-pressing silicone is located below the first heating wire.

[0021] By adopting the above technical solution, the silicone bag is used to limit the position of the packaging bag, and the first heating wire is used to seal the packaging bag.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a novel household multi-purpose sealing machine.

A first heating wire 17 is fixedly connected to the bottom of the heating wire support silicone 16, which can seal the packaging bag. An air pump 18 is fixedly connected to the right side of the main body 1. The airbag 13 is connected to the output end of the air pump 18 via an air tube, and a two-way solenoid valve 20 is connected between them. When the airbag 13 needs to be inflated, the air pump 18 is activated, and air is output into the airbag 13, causing the airbag 13 to inflate. A vacuum pump 19 is provided at the front end of the air pump 18 and is fixedly connected to the inner wall of the main body 1. The input end of the vacuum pump 19 is connected to the vacuum chamber 6 via an air tube, allowing it to evacuate air from the vacuum chamber 6.

[0028] Reference Figure 6 and Figure 7 The heating sealing assembly includes a through groove 27, which is located inside the top cover 22 and communicates with the interior of the top cover 22. A heating wire frame 28 is installed inside the through groove 27, and an ultraviolet lamp hole (not shown in the figure) is provided through the outer side of the heating wire frame 28. A second heating wire 23 is fixedly connected to the outside of the heating wire frame 28. A mica partition (not shown in the figure) for heat insulation is provided on the outer side of the heating wire frame 28, and the second heating wire 23 is installed on the mica partition. The heating wire frame 28 has six evenly distributed connectors 29 fixedly connected to its outer ring. Each of the six connectors 29 has a limit rod 30 that is slidably connected through it. The limit rod 30 has a second spring 31 sleeved on its outer ring. The second spring 31 is located between the connector 29 and the top cover 22. A fixing sheet metal 32 is fixedly connected between the ends of the two limit rods 30. A second airbag 33 is fixedly connected to the outside of the fixing sheet metal 32. An ultraviolet lamp plate 34 is fixedly connected to the middle of the inner side of the heating wire frame 28. The ultraviolet lamp plate 34 is a UV lamp, and its lamp beads correspond exactly to the ultraviolet lamp holes, so that the ultraviolet light can pass through the lamp holes and irradiate the lunch box to achieve the sterilization effect.

[0029] Inside the top cover 22, six limiting rods 30, which mate with six connecting pieces 29 around the perimeter of the heating wire frame 28, are equipped with six second springs 31. These second springs 31 continuously apply an upward force to the heating wire frame 28, ensuring that when the machine is not sealing the lunchbox, the lifting of the heating wire frame 28 does not contact the lunchbox support silicone. The heating wire frame 28 can be moved up and down by controlling the inflating and deflating of the second airbag 33. An air pump (not shown in the diagram) is installed inside the top cover 22. The second airbag 33 is connected to the air pump output and a solenoid valve via an air tube. When the lunchbox needs to be heated, the air pump starts, and air is blown out, causing the second airbag 33 to inflate, pushing the heating wire frame 28 downwards and ensuring close contact with the lunchbox support silicone on the machine body 1, thus guaranteeing the heating effect for sealing the lunchbox.

[0030] Reference Figure 1-5The sealing base 3 has a placement groove 4 at its top front end, and a bag-pressing silicone 5 is fixedly connected in the placement groove 4. The bag-pressing silicone 5 is used to limit the position of the packaging bag and, together with the first heating wire 17, seals the packaging bag. The bag-pressing silicone 5 is located below the first heating wire 17. A lower sealing silicone 26 is provided on the outer ring of the vacuum chamber 6, and the lower sealing silicone 26 is fixedly connected to the sealing base 3. The top of the sealing base 3 has a groove on the outside of the vacuum chamber 6, and the lower sealing silicone 26 is installed in the groove. Four limiting posts 9 are all through and slidably connected to the airbag sealing plate 11, so that the airbag sealing plate 11 can be stably raised and lowered along the four corner limiting posts 9. A first spring 10 is sleeved on the outer ring of the limiting post 9. The first spring 10 is located between the limiting protrusion 12 and the airbag sealing plate 11. The airbag sealing plate 11 can be lifted upward by the reset of the first spring 10. The output end of the blowing pump 18 is connected to the air bag 13 via an air tube, and the input end of the suction pump 19 is connected to the vacuum chamber 6 via an air tube (not shown in the figure). Both the blowing pump 18 and the suction pump 19 are equipped with a double-way solenoid valve 20 on their outer sides. The two ends of the double-way solenoid valve 20 are respectively connected to the vacuum chamber 6 and the air bag 13 via air tubes. When the double-way solenoid valve 20 is not in operation, both ends are sealed, preventing interference between the air bag 13 end and the vacuum chamber 6 end. When the double-way solenoid valve 20 is energized, the two air tubes are interconnected, connecting the air bag 13 end and the vacuum chamber 6 end, canceling out the negative and positive pressures at both ends, restoring both to atmospheric pressure. A sealing clip 25 is provided on the outside of the lunchbox slot 21, and the sealing clip 25 is fixedly connected to the body 1, facilitating the securing of the sealing film covering the lunchbox. A latch 24 is provided on the outside of the top cover 22, facilitating the locking of the top cover 22.

[0031] Working principle: When sealing a packaging bag, the open end of the bag to be sealed is laid flat on the sealing base 3, so that the bag opening covers the vacuum chamber 6, and the edge of the bag opening is placed above the pressure silicone 5 in the placement groove 4. At this time, the lower sealing silicone 26 on the outer ring of the vacuum chamber 6 and the subsequently pressed airbag sealing plate 11 form an initial sealing base. After the equipment is started, the air pump 18 delivers gas to the airbag 13 through the air pipe. During this process, the end of the double-way solenoid valve 20 connected to the airbag 13 is in a closed state. After the gas enters the airbag 13, the airbag 13 expands and pushes the bottom airbag sealing plate 11 to slide downward along the limiting post 9. During this process, the first spring 10 on the outer ring of the limiting post 9 is compressed by the airbag sealing plate 11 until the upper sealing silicone 15 at the bottom of the airbag sealing plate 11 is completely adhered to the lower sealing silicone 26 of the sealing base 3. At this time, the vacuum chamber 6 and the vacuum groove 14 form a sealed vacuum space. At this time, the vacuum pump 19 starts, and its input end is connected to the vacuum chamber 6 through an air pipe, which can evacuate the vacuum chamber 6. At the same time, the airbag sealing plate 11 drives the first heating wire 17 installed on it to make close contact with the bag-pressing silicone 5 installed on the sealing base 3, thereby ensuring the heat sealing effect. When the airbag 13 inflates, it ensures the working effect of vacuum sealing. The whole process avoids manual pressing, making it more convenient. After the vacuum sealing work is completed, the double-way solenoid valve 20 is activated, and the two air pipes are interconnected, connecting the end of the airbag 13 and the end of the vacuum chamber 6. The positive pressure of the airbag 13 and the negative pressure of the vacuum tank 14 cancel each other out, and both return to atmospheric pressure. The airbag sealing plate 11 will be lifted upward under the force of the first spring 10 installed at its four corners, thereby opening the vacuum chamber 6, making it easy to take out the vacuum bag. When sealing the lunchbox, place the food-filled lunchbox into the lunchbox slot 21, ensuring the lunchbox is centered. Then, take a sealing film of the appropriate size and cover the opening of the lunchbox, securing the edges of the sealing film with the sealing film clip 25 on the outside of the lunchbox slot 21 to prevent displacement. Next, flip the top cover 22 so that the second heating wire 23 inside the top cover 22 aligns with the sealing film at the opening of the lunchbox. When the machine is not sealing the lunchbox, the heating wire holder 28 is raised and does not contact the lunchbox support silicone. By controlling the inflating and deflating of the second airbag 33, the heating wire holder 28 moves up and down. The second airbag 33 is connected to the air pump output and a solenoid valve (not shown in the figure) via an air tube. When the lunchbox needs to be heated, the air pump starts, and air is blown out from the output, causing the second airbag 33 to inflate, pushing the heating wire holder 28 downwards, thus ensuring close contact with the lunchbox support silicone on the top of the machine body 1. This ensures that the second heating wire 23 fits tightly against the sealing film and the lunchbox opening, guaranteeing the heating effect for sealing the lunchbox. During the heating process, the air pump remains on to ensure that the second airbag 33 remains inflated. After heating is complete, the air pump stops working, the solenoid valve starts, thereby expelling the air from inside the second airbag 33, and the second airbag returns to its normal state. The heating wire holder 28 rebounds under the action of the second springs 31 around it, and then the top cover can be opened for easy access to the lunchbox.
