Description

TECHNICAL FIELD

[0002] A vacuum sealer is a device used to seal food, medicine and other items. Its working principle is to extract the air in the packaging bag, thereby creating a low-oxygen environment, which helps to extend the shelf life of the items, prevent oxidation and bacterial growth. Vacuum sealers are often used in homes, restaurants and food processing industries to maintain the freshness of food and extend the shelf life.

[0003] The existing vacuum machine can extract the gas in the vacuum bag, so an air outlet is arranged in the vacuum cavity to extract the gas in the vacuum bag and achieve vacuum sealing packaging of the vacuum bag. However, in actual use, the sealing ring arranged around the vacuum cavity is too tightly attached, causing the gas path of the vacuum bag to be sealed, thereby affecting the efficiency of the air outlet in extracting vacuum. In order to better extract the gas in the vacuum bag, a telescopic air nozzle is arranged in the main body. However, the existing telescopic air nozzle has two parts, the first part is a flat hollow tube, and the second part is an adapter for connecting a vacuum pump. When in use, the gas in the vacuum bag is extracted through the air nozzle, and the gas in the vacuum cavity is extracted through the air outlet arranged in the vacuum cavity.

[0027] A cover body 11 is arranged on the main body 1, and the cover body 11 and the main body 1 form a cavity, and a telescopic flow guide mechanism 3 is arranged inside the cavity. The main body 1 forms a lower chamber 13 at the side close to the cover body 11, and an air extraction device is arranged in the lower chamber 13. The lower chamber 13 is used to place a vacuum bag to be vacuumized and vacuumized by the air extraction device. The telescopic flow guide mechanism 3 is configured to switch between a first position and a second position. In the first position, the telescopic flow guide mechanism 3 extends into the vacuum bag and guides the gas to the lower chamber 13. In the second position, the telescopic flow guide mechanism 3 is retracted into a preset position. By arranging the telescopic flow guide mechanism 3, the flow guide plate 33 can extend into the inside of the vacuum bag, and the gas in the vacuum bag is guided to the vacuum chamber of the vacuum sealing machine through the gas guide channel 331 arranged on the flow guide plate 33, avoiding the problem of air path sealing caused by the sealing ring being too tight in the traditional design.

[0028] Further, the main body 1 is formed with a lower chamber 13, and a heating assembly is arranged near the lower chamber 13; the flip cover 2 is formed with an upper chamber at a position corresponding to the lower chamber 13, and a pressing strip is arranged near the upper chamber, the pressing strip is arranged corresponding to the heating assembly, and a sealing ring 14 is arranged around the upper chamber and the lower chamber 13, so as to improve the air tightness of the vacuum chamber in the closed state, the flip cover 2 can be operated between an open state and a closed state, in the closed state, the upper chamber and the lower chamber 13 form a closed space, i.e. a vacuum chamber, and the pressing strip and the heating assembly abut each other, in the open state, the upper chamber is away from the lower chamber 13; the main body 1 is provided with a controller, and an output end of the controller is electrically connected with a control end of a vacuum pump, the heating assembly and the telescopic flow guide mechanism 3.

[0029] Further, the main body 1 is formed with a cover 11, the cover 11 is internally provided with the telescopic flow guide mechanism 3 and the controller, the cover 11 is provided with an opening 12 on a side wall, the lower chamber 13 is arranged near the opening 12, a plurality of supporting plates 15 are arranged on one side of the lower chamber 13 near the opening 12, the supporting plates 15 are used to keep the bag opening of the vacuum bag in an open state, so as to facilitate the flow guide plate 33 to extend into the vacuum bag, and a plurality of air suction ports 16 are further arranged in the lower chamber 13, the air suction ports 16 are connected to the vacuum pump, the gas in the vacuum bag is guided into the vacuum chamber through the air guide channel 331, and the gas in the vacuum chamber is sucked away by the vacuum pump through the air suction ports 16, so that the vacuum chamber enters a negative pressure state, and the vacuum bag enters a vacuum state, and the sealing effect of the vacuum bag is improved.

[0030] Further, the telescopic flow guide mechanism 3 is provided with a flow guide plate 33, which is provided with a plurality of air guide channels 331 at the first end, which are used to guide the air into the lower chamber 13. In this embodiment, the air guide channels 331 are a plurality of parallel grooves formed on the surface of the flow guide plate 33. In order to improve the air extraction efficiency, the air guide channels 331 are provided on the upper surface and the lower surface of the flow guide plate 33. The air guide channels 331 are used to communicate the inside of the vacuum bag and the vacuum chamber. The length of the flow guide plate 33 is A, and the length of the air guide channel 331 is B. Then B is between 1 / 3A and 1 / 2A. By controlling the length of the air guide channel 331, it is ensured that the air guide channel 331 can guide the air in the vacuum bag into the vacuum chamber, avoiding the situation that the air path is sealed. At the same time, the structural strength of the flow guide plate 33 is ensured, avoiding the phenomenon that the flow guide plate 33 is broken during operation due to the length of the air guide channel 331 being too long. By embedding the air guide channel 331 in the flow guide plate 33, the thickness of the flow guide plate 33 can be effectively reduced. In the long-term use process, the sealing ring 14 may be deformed due to the thickness of the flow guide plate 33 being too thick, affecting the sealing effect of the sealing ring 14. In order to avoid the above problems, a clearance groove is provided on the sealing ring 14 corresponding to the flow guide plate 33. When the vacuum sealer is in the closed state, the clearance groove in the upper chamber and the clearance groove in the lower chamber 13 form a through hole for the flow guide plate 33 to pass through. When the flow guide plate 33 passes through the through hole, the sealing ring 14 will be attached to the flow guide plate 33 to prevent the air in the vacuum chamber from escaping, affecting the air tightness of the vacuum chamber. The flow guide plate 33 is connected with a transmission assembly 34 at the second end, and the transmission assembly 34 is electrically connected with the output end of the controller.

[0031] The telescopic flow guide mechanism 3 is configured to switch between a first position and a second position. In the first position, the flow guide plate 3 is extended from the opening 12 under the action of the sliding block 341 and enters the vacuum bag, so that the opening end of the air guide channel 331 is above the heating assembly. When the vacuum sealer executes the air extraction instruction, the air in the bag can be guided into the vacuum chamber. In the second position, the flow guide plate 3 is withdrawn from the vacuum bag under the action of the sliding block 341 and is retracted to a preset position. The preset position can be adjusted according to actual use needs. For example, if batch food preservation operation is performed, the flow guide plate 3 can be retracted to the vacuum chamber position to shorten the movement distance of the flow guide plate 3 and improve the work efficiency. If the main body is cleaned, the flow guide plate 3 can be retracted into the cover body 11.
