Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumping, in particular to an electric vacuum sealer. Background Art

[0002] The Mason jar is sealed by pumping air with an electric vacuum sealer. As shown in the patent with the application number CN202211085654X, the existing electric vacuum sealer includes a housing, an interface provided at the lower end of the housing, and an air pump installed in the housing. When in use, the interface is sleeved on the mouth of the Mason jar, and the air pump operates to extract the air in the Mason jar for sealing. Reducing the air in the Mason jar is beneficial to the preservation of food in the Mason jar.

[0003] When storing powdery food (such as nutritional products like milk powder, etc.) in the Mason jar, during the air extraction process of the existing electric vacuum sealer, the internal powdery food is easily extracted together. The powdery food enters the vacuum pump along with the air, which easily causes damage to the vacuum pump. Summary of the Utility Model

[0004] In order to solve the drawback that powdery food easily enters the vacuum pump when the existing electric vacuum sealer works, the utility model provides an electric vacuum sealer, which can prevent powdery food from entering the vacuum pump to prevent damage to the vacuum pump.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] An electric vacuum sealer includes a housing and an air pump. A groove that can accommodate the mouth of the Mason jar is provided at the lower end of the housing. A sealing ring adapted to the Mason jar is provided at the mouth of the groove. The air pump is installed in the housing. An air extraction port connected to the air pump is provided at the bottom of the groove; the vacuum sealer further includes a powder blocking member, which includes a connecting pipe, a filter screen, and a powder blocking plate. The upper end of the connecting pipe is connected to the air extraction port, the lower end of the connecting pipe is closed and fixedly connected to the powder blocking plate. The edge of the powder blocking plate protrudes from the side surface of the connecting pipe. Air holes are provided on the side surface of the connecting pipe, and the filter screen is installed on the air holes.

[0007] Through the above setting, after the vacuum sealer extracts the powdery food, the powder blocking plate and the filter screen block the powdery food from entering the air pump, thereby preventing damage to the air pump.

[0008] Further, the ratio of the radius of the powder blocking plate to the radius of the groove is greater than 4 / 5.

[0009] Through the above setting, the radius of the powder blocking plate is larger, increasing the contact area between the powder blocking plate and the air flow, so that the powdery food in the air flow is more likely to adhere to the powder blocking plate.

[0010] Further, the powder blocking plate is arranged parallel to the bottom of the groove, and the distance between the powder blocking plate and the bottom of the groove is less than or equal to centimeters.

[0011] With the above settings, the distance between the powder baffle and the groove is small, making it easier for the powdered food in the air flow to adhere to the powder baffle and reducing the powdered food in the air flow.

[0012] Furthermore, the upper end of the connecting pipe is provided with an external thread that is threadedly connected to the air extraction port.

[0013] With the above settings, the connecting pipe can be installed on the air extraction port by threading, facilitating the disassembly and assembly of the powder blocking member.

[0014] Furthermore, a plurality of air holes are uniformly arranged along the circumference of the connecting pipe.

[0015] With the above settings, the air extraction speed of the air extraction pump is increased to improve the sealing efficiency.

[0016] Furthermore, the powder blocking member further includes rib strips, which are fixedly connected to the upper side of the powder baffle.

[0017] With the above settings, while increasing the strength of the powder blocking member, the surface area of the powder blocking member is further increased, so that the powdered food in the air flow can more easily adhere to the powder blocking member.

[0018] Furthermore, the distance between the upper side of the rib strip and the bottom of the groove is less than 2 millimeters.

[0019] With the above settings, the air flow collides with the rib strip above the powder baffle and adheres to the rib strip, further reducing the powdered food in the air flow.

[0020] Furthermore, the number of rib strips is the same as the number of air holes and they correspond one by one. The rib strip is a V-shaped structure with an opening facing the corresponding air hole, and the rib strip is arranged on the radial outside of the corresponding air hole.

[0021] Furthermore, the vacuum sealer further includes a rechargeable battery and a charging port. The rechargeable battery is installed in the housing to supply power to the air extraction pump. The charging port is arranged on the outer surface of the housing and can be connected to a charging cable to charge the rechargeable battery.

[0022] With the above settings, the vacuum sealer is powered by the rechargeable battery. After the power is exhausted, the rechargeable battery is charged through the charging port, increasing the convenience of using the vacuum sealer.

[0023] Furthermore, the rechargeable battery is set as a lithium battery.

[0024] With the above settings, the lithium battery has a high energy density, so that the vacuum sealer of the present application has a long battery life. Description of the Drawings

The upper end of the connecting pipe 7 is connected to the air suction port 6, and the lower end of the connecting pipe 7 is closed and fixedly connected to the powder blocking plate 9. The edge of the powder blocking plate 9 protrudes from the side of the connecting pipe 7, and the side of the connecting pipe 7 is provided with air holes, and the filter screen 8 is installed on the air holes.

[0031] Through the above arrangement, after the vacuum sealer extracts the powdery food, the powder blocking plate 9 and the filter screen 8 prevent the powdery food from entering the vacuum pump 4, thereby preventing the vacuum pump 4 from being damaged.

[0032] The shell 3 of the present application is basically a cylinder, the groove is circular and coaxially arranged at the lower end of the shell 3, the sealing ring 5 is arranged on the inner side of the notch of the groove, the inner diameter of the sealing ring 5 is adapted to the outer diameter of the mouth of the Mason jar, to ensure that the mouth of the Mason jar has good air tightness after being inserted into the groove, the vacuum pump 4 is powered by a battery or a plug-in, the powder baffle 9 is circular, the lower end of the connecting pipe 7 is connected to the center of the powder baffle 9, the suction port 6 is arranged at the center of the groove, so that the air flow around the powder baffle 9 is more uniform, and when the vacuum pump 4 is running, the air in the Mason jar is sucked out, such as Figure 4 As shown, the airflow passes through the edge of the powder blocking plate 9 and moves toward the filter 8 along the upper surface of the powder blocking plate 9. When the airflow contains powdery food, the powdery food will adhere to the powder blocking plate 9 to reduce the powdery food in the airflow; finally, the airflow passes through the filter 8 and the air holes, and the filter 8 filters out the powdery food in the airflow to prevent the powdery food from entering the vacuum pump 4 and damaging the vacuum pump 4; preferably, the connecting pipe 7 is detachably connected to the vacuum port 6 to facilitate the removal of the powder blocking component for cleaning.

[0033] As an implementation method, the ratio of the radius of the powder blocking plate 9 to the radius of the groove is greater than 4 / 5.

[0034] Through the above settings, the radius of the powder baffle 9 is made larger, increasing the contact area between the powder baffle 9 and the air flow, so that the powdery food in the air flow is more likely to adhere to the powder baffle 9.

[0035] Specifically, the gap width between the edge of the powder baffle 9 and the side wall of the groove is greater than or equal to 5 mm, so as to ensure that the air flow can move upward more smoothly.

[0036] As a way of implementation, the powder baffle 9 is arranged parallel to the bottom of the groove, and the distance between the powder baffle 9 and the bottom of the groove is less than or equal to 1 centimeter.

[0037] Through the above settings, the distance between the powder baffle 9 and the groove is made smaller, so that the powdery food in the air flow is more likely to adhere to the powder baffle 9, reducing the powdery food in the air flow.

[0038] Specifically, the distance between the powder baffle 9 and the bottom of the groove is greater than or equal to 5 mm to ensure that the air flow can move smoothly along the upper surface of the powder baffle 9 towards the filter screen 8.

[0042] Through the above settings, the air extraction speed of the air extraction pump 4 is increased to improve the sealing efficiency.

[0043] As a way of implementation, the powder baffle member further includes a rib 10, and the rib 10 is fixedly connected to the upper side of the powder baffle 9.

[0044] Through the above settings, while increasing the strength of the powder baffle member, the surface area of the powder baffle member is further increased, so that the powdery food in the air flow can adhere to the powder baffle member more easily.

[0045] As a way of implementation, the distance between the upper side of the rib 10 and the bottom of the groove is less than 2 mm.

[0046] Through the above settings, the air flow collides with the rib 10 above the powder baffle 9 and adheres to the rib 10, so as to further reduce the powdery food in the air flow.

[0047] As a way of implementation, the number of ribs 10 is the same as the number of air holes and they correspond one by one. The rib 10 is a V-shaped structure with an opening facing the corresponding air hole, and the rib 10 is arranged radially outside the corresponding air hole.

[0048] As an implementation, the vacuum sealer further includes a rechargeable battery and a charging port 11. The rechargeable battery is installed in the housing 3 to supply power to the air pump 4. The charging port 11 is provided on the outer surface of the housing 3 and can be connected to a charging cable to charge the rechargeable battery.

[0049] With the above arrangement, the vacuum sealer is powered by the rechargeable battery. After the power is exhausted, the rechargeable battery can be charged through the charging port 11, which increases the convenience of using the vacuum sealer.
