Description

Technical Field

[0001] This utility model relates to the field of vacuum device technology, specifically a convenient vacuum device for food preservation. Background Technology

[0002] Vacuum sealing devices are essential tools in the food preservation field, playing a crucial role in the food industry. They effectively extend the shelf life of food. By removing air from the packaging, a low-oxygen environment is created, inhibiting the growth and reproduction of aerobic microorganisms and significantly reducing the risk of food spoilage. Whether it's perishable foods like meat and seafood, or dried goods like grains and nuts, they can maintain freshness for a longer period under vacuum. This device also maximizes the preservation of the food's nutritional components and original flavor. By reducing contact between oxygen and food, it prevents oxidation of food components, maintaining the food's color, texture, and nutritional value. Simultaneously, it helps prevent food from becoming damp and moldy, keeping food dry and hygienic. Vacuum sealing devices are indispensable in food processing, storage, and transportation, providing strong guarantees for food safety and quality, and meeting people's demand for high-quality food. According to the utility model disclosed in patent authorization announcement number CN204150264U, a vacuuming device for food seasonings includes a vacuuming tube, a heater, a vacuum machine, a vacuuming device cylinder, a discharge port, a feed port, a support frame, and rollers. The vacuuming cylinder is surrounded by a support frame, and rollers are arranged below the support frame. In order to facilitate the drying of the vacuuming cylinder and the preservation of food seasonings, a heater is provided inside the vacuuming device, which adopts an electric heating method. The cylinder of the vacuuming device is connected to the vacuum machine through a vacuuming tube. The feed port is set at the top of the vacuuming device, and the discharge port is set at the bottom.

[0003] However, there are certain issues with the disassembly of the vacuum pump at the end of the vacuuming process in food preservation vacuum devices. During disassembly, a small amount of outside air can enter the vacuum bag. Although the device effectively removes a large amount of air from the bag during the vacuuming process, creating a relatively vacuum environment, the intrusion of air during disassembly disrupts the original vacuum state. This may cause some food inside the vacuum bag to re-expose to air, increasing the risk of food spoilage and weakening the preservation effect of the vacuum device to some extent. Utility Model Content

[0004] The purpose of this invention is to provide a convenient food preservation vacuum device, which solves the problem that a small amount of air will enter the vacuum bag when the vacuum pump is disassembled at the end of the vacuuming process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient food preservation vacuum device, comprising a vacuum pump, a fixed tube fixedly connected to the left side of the vacuum pump, a connecting tube inserted into the outside of the fixed tube, a vacuum bag fixedly connected to the outside of the connecting tube, a fixed block fixedly connected to the left side of the vacuum pump, the fixed block contacting the connecting tube, a limiting sleeve rotatably connected to the outside of the fixed block, a protrusion fixedly connected inside the limiting sleeve, the protrusion slidingly connected to the fixed block, a positioning plate fixedly connected to the right side of the vacuum bag, a positioning rod fixedly connected to the left side of the vacuum pump, the positioning rod slidingly connected to the positioning plate, and a sealing mechanism provided on the connecting tube.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4A convenient food preservation vacuum device includes a vacuum pump 1, a fixed tube 2 fixedly connected to the left side of the vacuum pump 1, a connecting tube 3 inserted into the outside of the fixed tube 2, a vacuum bag 31 fixedly connected to the outside of the connecting tube 3, a fixed block 4 fixedly connected to the left side of the vacuum pump 1, the fixed block 4 contacting the connecting tube 3, and a limiting sleeve 41 rotatably connected to the outside of the fixed block 4, the limiting sleeve 41 contacting the vacuum pump 1.

[0022] Please see Figure 2-4 The limiting sleeve 41 is connected to the connecting pipe 3 by a thread. The design of the limiting sleeve 41 can limit the connecting pipe 3. The limiting sleeve 41 has a protrusion 42 fixedly connected inside, and the protrusion 42 is slidably connected to the fixing block 4. The right side of the vacuum bag 31 is fixedly connected to the positioning plate 43, which is slidably connected to the connecting pipe 3 and contacts the limiting sleeve 41. The design of the positioning plate 43 can position the connecting pipe 3. The left side of the vacuum pump 1 is fixedly connected to the positioning rod 44, which is slidably connected to the positioning plate 43. The connecting pipe 3 is provided with a sealing mechanism 5.

[0023] Please see Figure 2-4 The sealing mechanism 5 includes a slide plate 51, which is slidably connected inside the connecting pipe 3. A sealing gasket 52 is fixedly connected to the right side of the slide plate 51. The sealing gasket 52 is slidably connected to the connecting pipe 3. A push rod 53 is fixedly connected inside the slide plate 51. The push rod 53 is slidably connected to the sealing gasket 52 and the connecting pipe 3. The push rod 53 can move the sealing gasket 52. A baffle 54 is fixedly connected inside the connecting pipe 3. The baffle 54 is slidably connected to the push rod 53. A first through hole 541 is opened inside the baffle 54. The baffle 54 can limit the sealing gasket 52.

[0024] Please see Figure 2-4 The fixed tube 2 is internally fixedly connected to a top plate 55, which is in contact with the top rod 53. The top plate 55 has a second through hole 551 inside. The connecting tube 3 has an air inlet hole 56 inside. A spring 57 is provided on the outside of the top rod 53. One end of the spring 57 is in contact with the connecting tube 3, and the other end of the spring 57 is in contact with the sliding plate 51. The design of the spring 57 can drive the sealing gasket 52 to reset. The design of the sealing mechanism 5 can prevent air from entering the vacuum bag 31 when the vacuum bag 31 is disassembled.

[0025] The specific implementation process of this utility model is as follows: In use, by inserting the connecting pipe 3 into the fixed pipe 2, the positioning rod 44 is slidably sleeved with the positioning plate 43, and then the limiting sleeve 41 is rotated to make the limiting sleeve 41 and the connecting pipe 3 undergo threaded movement, thereby limiting the connecting pipe 3 and keeping the connection between the connecting pipe 3 and the fixed pipe 2 stable.

[0026] After the connecting pipe 3 is inserted into the fixing pipe 2, the push rod 53 will contact the top plate 55, and the push rod 53 will drive the sealing gasket 52 to move through the sliding plate 51. The sliding plate 51 will squeeze the spring 57 and move the sealing gasket 52 to the left side of the air inlet 56, so that the gas in the vacuum bag 31 can enter the connecting pipe 3 through the air inlet 56, thus facilitating the vacuum pump 1 to evacuate the vacuum bag 31.

[0027] When disassembling the vacuum bag 31, the connecting tube 3 is separated from the fixing tube 2. The spring force of the spring 57 can then drive the sliding plate 51 to move, causing the sliding plate 51 to move the sealing gasket 52 back to the right side of the air inlet 56, thus blocking the air inlet 56 again and preventing air from entering the vacuum bag 31.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
