The vacuum pump 140 of the vacuum pumping apparatus 100 generally comprises a motor and a pump body, wherein the motor is used for driving the pump body to rotate, so as to drive air to flow along a fixed direction, thereby achieving the effect of pumping air on one side to the other side. The vacuum pump 140 further comprises a housing for mounting the motor and pump body within the housing, thereby providing a protective effect to the motor and pump body, and in addition, the housing also provides a cavity passage for air circulation. The shell is also provided with an air inlet 141a and an air outlet 142, the air inlet 141a is connected with the air extraction hole 131a, and the air outlet 142 is communicated with an exhaust hole formed in the cavity wall of the accommodating cavity 101, so that air extracted from the container to be vacuumized through the air extraction hole 131a enters the vacuum pump 140 through the air inlet 141a connected with the air extraction hole, the extracted air is exhausted to the air outlet 142 under the action of the vacuum pump 140, and the exhausted air is finally exhausted to the outside of the accommodating cavity 101 through the exhaust hole; after the process is continued for a while, most or all of the air in the container is exhausted, so that the effect of vacuumizing the container needing vacuumizing is achieved. In addition, the control circuit board is connected to the vacuum pump 140, and controls the on and off states of the vacuum pump 140 under the control of the control circuit board. In addition, the power supply module is electrically connected to the control circuit board, so that the power supply module can supply power to the control circuit board to ensure the normal operation of the whole vacuum pumping device 100. It is understood that the vacuum pump 140, the control circuit board and the power supply module are located in the accommodating chamber 101 and connected to the mounting bracket 120, or the mounting bracket 120 is connected to the housing, and may be fixedly connected or detachably connected. The present invention preferably has a detachable connection, such as a snap connection, a screw connection, etc., to facilitate assembly, maintenance, etc.

Because the vacuum extractor 100 inevitably sucks food materials while extracting air from a container to be vacuumized, in the technical scheme of the present invention, an isolation buffer cavity 170 is formed outside a casing of the vacuum extractor, and the isolation buffer cavity 170 communicates with the pumping hole 131a and the container to be vacuumized, so that food to be pumped or residual juice splashed during a whipping process firstly passes through the isolation buffer cavity 170 and is attached to an inner wall of the isolation buffer cavity 170, thereby preventing the food from being directly attached to the pumping hole 131a to block the pumping hole 131a, and achieving a good vacuum extracting effect. Further, the isolation buffer cavity 170 is located at the bottom of the shell, so that when the vacuum pumping device 100 is located above the container, the isolation buffer cavity 170 is closer to the container, and therefore a part of food materials are stopped on a first suction path, and a subsequent suction path is ensured to be more smooth.

Specifically, in order to achieve a good communication effect between the air inlet 141a of the vacuum pump 140 and the air suction hole 131a on the cavity wall of the accommodating chamber 101, a connecting column 141 is convexly arranged on a side of the vacuum pump 140 opposite to the air suction hole 131a, the air inlet 141a is opened on the connecting column 141, and the connecting column 141 is inserted into the air suction hole 131a and is hermetically connected with the inner wall of the air suction hole 131 a. The connecting column 141 is convexly arranged on one side of the vacuum pump 140 opposite to the air suction hole 131a, the connecting column 141 is inserted into the air suction hole 131a and is hermetically connected with the inner wall of the air suction hole 131a, and the air inlet 141a is formed in the connecting column 141, so that air coming in and going out from the air suction hole 131a can only pass through the air inlet 141a of the vacuum pump 140, and the air is discharged into the accommodating cavity 101 through the air outlet 142 in the operation process of the vacuum pump 140. Specifically, when the connection column 141 of the vacuum pump 140 is hermetically connected to the inner wall of the pumping hole 131a, a sealing ring may be disposed between the connection column 141 and the inner wall of the pumping hole 131 a; of course, an internal thread may be disposed on the inner wall of the air exhaust hole 131a, and an external thread may be disposed on the outer wall of the connection column 141, so that the sealing effect of the internal thread and the external thread is achieved by screwing the internal thread and the external thread.

In addition, the shape of the isolation buffer cavity 170 is not limited, and may be, for example, a circle, a polygon, or the like. The isolation buffer cavity 170 may be connected to the housing by an integral connection structure or a separate connection structure. It is understood that the container to be evacuated mentioned above may be a cup, a tub, a bag, or the like.

According to the technical scheme of the invention, the one-way valve 160 is arranged on the pipeline communicated with the air suction hole 131a or the air inlet 141a, and the one-way valve 160 is communicated with the air suction hole 131a towards the air inlet 141a, so that the air in the container can only be discharged outside under the action of the vacuum pump 140, and the outside air is prevented from entering the container. Meanwhile, the isolation cache cavity 170 which is communicated with the air suction hole 131a and a container to be vacuumized is arranged on the outer wall of the shell, so that food sucked in the vacuumizing process is firstly adsorbed to the wall of the isolation cache cavity 170, and the effect of preventing the air suction hole 131a from being blocked is achieved.

By dividing the housing into the upper cover 110 and the lower cover 130, when the mounting bracket 120 is detachably connected to the upper cover, the vacuum pump 140 and other parts can be mounted on the mounting bracket 120, and then the mounting bracket 120 is connected to the upper cover 110, so that the assembly is easy for a worker, and the problem that large parts are difficult to assemble is avoided. Similarly, the above effect can be achieved when the mounting bracket 120 is detachably connected to the lower cover 130, or when the mounting bracket 120 is detachably connected to both the upper cover 110 and the lower cover 130. Specifically, the detachable connection manner includes a snap connection, a screw connection, a magnetic connection, or the like.

Based on the above case having the upper cover 110 and the lower cover 130, the present invention preferably: the mounting bracket 120 is detachably coupled to the upper cover 110 at one side and to the lower cover 130 at the other side.

The air vent may be a circular hole or a polygonal hole opened at any position of the upper cover 110 or the lower cover 130, or a connection gap between the upper cover 110 and the lower cover 130 may be used as the air vent. The upper cover 110 and the lower cover 130 may be detachably connected by a screw connection or a snap connection.

Specifically, in order to stop some food materials with a large volume outside the vacuum extractor 100, please refer to fig. 2, fig. 3, fig. 6, fig. 7, and fig. 8, a groove is formed on a surface of the lower cover 130 away from the upper cover 110, the air exhaust hole 131a is opened on a bottom wall of the groove, the lower cover 130 is further detachably connected with a cover plate 180, and the cover plate 180 is provided with a sieve hole 181 communicating with the isolation buffer cavity 170.

Through deviating from the surface of upper cover 110 at lower cover 180 and being formed with the cell body, the diapire at this cell body is seted up to aspirating hole 131a, lower cover 130 still can be dismantled and be connected with a lid and close cell body open-ended apron 180, set up the sieve mesh 181 that the intercommunication keeps apart cache chamber 170 on the apron 180, make this apron 180 can stop the great edible material of volume outside evacuating device 100, can guarantee again that the container can be through sieve mesh 181 and aspirating hole 131a intercommunication on the apron 180, thereby guarantee that the air in the container still can pass through aspirating hole 131a, and then discharge outside the container through vacuum pump 140's effect. In addition, the cover plate 180 is detachably connected to the lower cover 130, so that the user can conveniently clean the inner wall of the buffer cavity 170 by removing the cover plate 180.

It is understood that the sieve holes 181 may be circular holes, square holes, or linear holes.

By setting up sieve mesh 181 into long strip shape, and the width dimension B of this sieve mesh 181 satisfies: b is more than 0mm and less than or equal to 0.8mm, so that the sieve holes 181 have the effect of stopping most food materials properly. If B is greater than 0.8mm, the width of the sieve hole 181 is too wide, so that many food materials can pass through the sieve hole 181, and more food materials are firstly adhered to the inner wall of the isolation buffer cavity 170, and then the extraction hole 131a is blocked after a period of time, which affects the normal use of the vacuum apparatus 100.

Referring to fig. 7, the thickness of the area of the cover plate 180 where the screen holes 181 are formed is defined as D, where D is greater than 0.2mm and less than or equal to 1.2 mm.

The cover plate 180 can bear certain impact strength and can ensure better ventilation effect. If the thickness D of the area of the cover plate 180 where the sieve holes 181 are formed is less than or equal to 0.2mm, the thickness of the cover plate 180 is small, and the strength of the cover plate 180 after the sieve holes 181 are formed is difficult to ensure; if D is greater than 1.2mm, the thickness of the cover plate 180 is thick, which affects the effect of sucking air in the container.

Further, the distance between the cover plate 180 and the bottom wall of the tank body is defined as L, and L is larger than 1mm and smaller than or equal to 10 mm.

If the distance L between the cover plate 180 and the bottom wall of the tank body is less than or equal to 1mm, the depth of the cavity of the isolation cache cavity 170 is shallow, so that the cavity is quickly filled with food materials, and a user needs to frequently clean the inner wall of the cavity of the isolation cache cavity 170; if the distance L between the cover plate 180 and the bottom wall of the tank body is larger than 10mm, the depth of the cavity for isolating the cache cavity 170 is deep, so that the air exhaust efficiency can be influenced after certain food materials are accumulated in the cavity.

Further, referring to fig. 5, the lower cover 130 further has a pressure relief hole 131b, the accommodating cavity 101 further has a pressure relief switch assembly, the upper cover 110 or the lower cover 130 has an air inlet, and the pressure relief switch assembly is fixedly connected to the mounting bracket 120 and communicates the pressure relief hole 131b with the air inlet.

Specifically, the pressure relief switch assembly includes a pressure relief valve 150, and the effect of venting gas through the pressure relief valve 150 (or blocked by the pressure relief valve 150) is achieved by controlling the open (or closed) state of the pressure relief valve 150.

On the basis that the lower cover 130 has the pressure relief hole 131b, the pressure relief hole 131b is opened in the bottom wall of the tank body and is communicated with the isolation buffer cavity 170.

Through communicating pressure release hole 131b with isolation buffer memory chamber 170 for outside air through relief valve 150 can pass pressure release hole 131b and get into isolation buffer memory chamber 170, and then gets into the container through the sieve mesh 181 of apron 180 in, thereby realize the pressure release process, realize the effect that the atmospheric pressure of outside air and air in the container is the same, make the user open the lid of container more easily, further eat the edible material in the edible container.
