Optionally, the host top case 101 has a host convex top 101a, and the host convex top 101a is used for mounting the connection mechanism 200.

The container body 310 is used for carrying food materials to be processed. The shape of the container body 310 is in principle not limited and may be cylindrical, conical, etc. In this embodiment, the container body 310 is tapered in shape. The container body 310 is detachably mounted on the main body unit 100, and the cutting tool 320 at the bottom of the container body 310 is connected to the motor 103 in the main body unit 100. Alternatively, the cutting tool 320 may be directly connected to the output shaft of the motor 103, or may be connected to the output shaft of the motor 103 via a clutch or the like. When the motor 103 rotates, the cutting tool 320 may be driven to rotate to stir and cut the food material in the container body 310.

Optionally, the container lid mechanism 400 further includes a container lid seal 403 and a container lid seal 402. The container lid gasket 402 is located on the end surface of the top of the container body 310 and abuts against the lower end surface of the container lid 401 to form a seal. The container lid seal ring 403 is positioned on the inner wall of the top opening of the container body 310, and abuts against the circumferential end surface of the container lid 401 to form a seal.

The air tube 105 is located partially within the host mechanism 100 and partially within the connection mechanism 200, such that the air tube 105 is connected to the exhaust cap 501 assembly via the connection mechanism 200. Illustratively, the connection mechanism 200 has a suction nozzle 204, one end of the air tube 105 away from the suction pump 106 is connected to the suction nozzle 204, and the suction nozzle 204 can be connected to the exhaust nozzle 501a of the exhaust cover 501, so that the suction pump 106 can vacuum the container body 310 through the air tube 105, the suction nozzle 204 and the exhaust nozzle 501 a.

Further, one end of the connection mechanism 200 is connected to the main body mechanism 100, and in particular, one end of the connection mechanism 200 is rotatably mounted to the main body protrusion top portion 101a of the main body upper case 101. In this way, the connection mechanism 200 is rotatable relative to the host top case 101 between an operational position above the container lid 401 and an open position. In this embodiment, the connection mechanism 200 is rotated up and down. The open position of the linkage 200 is above the working position, as shown in fig. 2 and 4. When the connection mechanism 200 is rotated to the working position, the connection mechanism 200 is connected to the venting cap mechanism 500 in the container cover 401, and at this time, the suction nozzle 204 is connected to the venting nozzle 501a of the venting cap 501, so that the container body 310 can be evacuated. When the link mechanism 200 is rotated to the open position, the suction nozzle 204 is separated from the exhaust nozzle 501a, and at this time, the exhaust nozzle 501a is communicated with the external environment.

As shown in fig. 4 to 6, the suction nozzle 204 is supported by an elastic material and is disposed in a horn shape. That is, the suction nozzle 204 has a certain elasticity. After the suction nozzle 204 is sleeved on the exhaust nozzle 501a, the inner wall of the suction nozzle 204 is abutted to the outer wall of the exhaust nozzle 501a, and during vacuum pumping, the inner wall of the suction nozzle 204 and the outer wall of the exhaust nozzle 501a can be tightly connected to form effective surface connection, so that the sealing effect is good, and air-tight connection and air suction can be performed at the moment. When the vacuum degree in the container body 310 reaches a predetermined vacuum degree, the motor 103 may drive the cutting tool 320 to rotate, completing the vacuum cutting. After the vacuum cutting is completed, the connecting structure can be directly removed. Specifically, when the suction nozzle 204 initially moves upward, the edge of the suction nozzle 204 is deformed by a tensile force and slides along the air discharge nozzle 501a until being separated, and then the suction nozzle 204 is separated from the air discharge nozzle 501a of the air discharge cover 501 by its own elasticity, so that the container body 310 can be taken out. Optionally, the suction nozzle 204 further has a nozzle channel 204b, and the nozzle channel 204b communicates the air pipe 105 with the nozzle opening 204a of the suction nozzle 204 after the air pipe 105 is installed in the suction nozzle 204.

Referring to fig. 4 and 14, in the vacuum mixer 10 of the present invention, the trumpet-shaped suction nozzle 204 is engaged with the exhaust nozzle 501a of the exhaust cover 501 to vacuumize the container body 310, and the suction nozzle 204 is elastically deformed and gradually separated from the exhaust nozzle 501a to take out the container body 310 when the connecting mechanism 200 is moved from the operating position to the open position. The problem that the process of taking off the container after cutting is finished is complex at present is effectively solved, the container mechanism 300 can be taken out by removing the connecting mechanism 200, the cut container mechanism 300 can be taken out conveniently, the operation process is simple, and the use by a user is convenient.

As shown in fig. 3-6, 9, 10, and 13, in one embodiment, the exhaust nozzle 501a has an exhaust opening 501a2, and the upper portion of the exhaust opening 501a2 is an exhaust outlet sealing surface 501a1 for mating with the nozzle opening sealing surface 204a1 of the nozzle 204. The nozzle sealing surface 204a1 is a sloped or arcuate surface and the exhaust outlet sealing surface 501a1 conforms to the shape of the nozzle sealing surface 204a 1.

The exhaust nozzle 501a is located at the upper central axis of the exhaust cover 501, and the exhaust nozzle 501a is similar to the mouth of a pig. The exhaust opening 501a2 of the exhaust nozzle 501a faces upward, and the top of the exhaust opening 501a2 is an upwardly convex oblique edge forming the exhaust port sealing surface 501a 1. The suction nozzle 204 has a nozzle opening 204a, and the nozzle opening 204a is formed in a trumpet shape. The opening 204a2 of the nozzle 204a faces downward, and the inner wall of the nozzle 204a is a beveled nozzle sealing surface 204a 1. When the coupling mechanism 200 is in the operative position, the nozzle port sealing surface 204a1 engages the exhaust port sealing surface 501a1 in a suction-tight manner. At this time, the space formed by the exhaust cap 501 and the suction nozzle 204 communicates with the air tube 105 through the nozzle passage 204b to form a closed cavity of the air tube 105.

The nozzle sealing surface 204a1 and the exhaust outlet sealing surface 501a1 may be both sloped or curved, which ensures a reliable seal between the nozzle sealing surface 204a1 and the exhaust outlet sealing surface 501a 1. Moreover, the sloped or arcuate surfaces ensure that the nozzle sealing surface 204a1 gradually disengages from the exhaust outlet sealing surface 501a1 when the coupling mechanism 200 is removed from the operating position, facilitating removal of the coupling mechanism 200.

Referring to fig. 3 to 10 and 13, in an embodiment, the lower portion of the exhaust nozzle 501a has a horizontal seal 501b, the exhaust cap 501 further has an exhaust cap center hole 501c located on the horizontal seal surface 501b, and an exhaust cap exhaust hole 501f located on the periphery of the exhaust cap center hole 501c, and the exhaust cap exhaust hole 501f communicates with the upper and lower spaces of the exhaust cap 501. The exhaust cover mechanism 500 further comprises a one-way air valve 503, the one-way air valve 503 is mounted in the exhaust cover central hole 501c, and the one-way air valve 503 can abut against or be far away from the horizontal sealing surface to close or open the exhaust cover exhaust hole 501 f.

The one-way air valve 503 has a one-way air valve sealing surface 503a, and the one-way air valve sealing surface 503a can be selectively attached to the horizontal sealing surface 501B in an airtight manner so as to open or close the exhaust hole 501f of the exhaust cover and implement communication and isolation between the air pipe sealed cavity B and the container cavity A1.

Optionally, the number of the exhaust cover exhaust holes 501f is multiple, the exhaust cover exhaust holes 501f are circumferentially arranged on the periphery side of the exhaust cover central hole 501c, the exhaust cover central hole 501c and the exhaust cover exhaust holes 501f which are circumferentially arranged are coaxially arranged, and the exhaust cover exhaust holes 501f communicate with the upper space and the lower space of the exhaust cover 501. Thus, the gas in the container body 310 can be discharged through the discharge cap discharge hole 501 f.

When the connecting mechanism 200 is in the working position and the container body 310 is vacuumized, the one-way valve sealing surface 503a of the one-way valve 503 is far away from the horizontal sealing surface 501B, at this time, the exhaust cover exhaust hole 501f is in the open state, the air pipe sealed cavity B is communicated with the container cavity a1 of the container body 310, and the air in the container body 310 can be exhausted. At the moment when the suction nozzle 204 is removed, the horizontal sealing surface 501B of the one-way air valve is abutted, the exhaust hole 501f of the exhaust cover is in a sealing state, the air pipe sealed cavity B is isolated from the container cavity A1 of the container body 310, and air in the external environment cannot enter the container cavity A1.

Referring to fig. 3 and 9 to 12, in one embodiment, the container cover 401 has an upper outer ring rib 401d having a ring shape and an upper inner ring rib 401c located inside the upper outer ring rib 401d, and the exhaust cover 501 has a lower ring rib 501 g. The exhaust cover 501 is mounted on the container cover 401, the lower ring rib 501g is located between the upper outer ring rib 401d and the upper inner ring rib 401c, the lower ring rib 501g abuts against the upper outer ring rib 401d, the upper inner ring rib 401c surrounds the outer side of the end of the exhaust nozzle 501a far away from the suction nozzle 204, and the upper outer ring rib 401d, the lower ring rib 501g, the exhaust nozzle 501a and the upper inner ring rib 401c surround the circular air flow channel.

As shown in fig. 9 to 14, the upper outer ring rib 401d of the container cover 401 is engaged with the lower ring rib 501g of the exhaust cover 501 and sealed at the joint by the exhaust cover gasket 502 to ensure the sealing property at the joint of the container cover 401 and the exhaust cover 501. At this time, container cover 401 is engaged with venting cover 501 and forms an inner space in the coupling bead, and is partitioned into a circular space A3 and a circular space a2, which are coaxial, by upper inner bead 401c of container cover 401, to form a loop-shaped air flow passage. The container lid vent hole 401a is opened between the upper outer ring rib 401d and the upper inner ring rib 401c, and at this time, the container cavity a1 of the container body 310 communicates with the circular space a2 and the circular space A3 of the container lid 401 to form a container closed cavity a.

Thus, when the container body 310 is evacuated, the gas in the container body 310 enters the circular space a1 through the container lid vent hole 401a, enters the circular space a2 through the gap between the upper inner ring rib 401c and the exhaust lid 501, enters the gas tube sealed chamber B through the exhaust lid 501 vent hole 501f of the exhaust lid 501, and is delivered to the air pump 106 through the gas tube 105.

In one embodiment, the exhaust cover 501 has a slag stop 501d, and the slag stop 501d is disposed at an end of the exhaust nozzle 501a away from the suction nozzle 204 and extends in a circumferential direction. The slag blocking edges 501d are located at the top and inside the top of the upper inner ring rib 401c and form an air permeable gap in cooperation with the upper inner ring rib 401 c. The slag trap 501d serves to block the passage of slag. After the slag blocking edge 501d is protruded, the ventilation channel between the upper inner ring rib 401c and the exhaust cover 501 can be bent. Thus, the upper inner ring rib 401c or the exhaust cover 501 can block the residue from entering the circular space a2, and the exhaust cover mechanism 500 and the connection mechanism 200 can be cleaned conveniently.

Referring to fig. 4, 15 to 17, in an embodiment, the connection mechanism 200 includes a first upper connection housing 201, a first lower connection housing 202, a first nozzle support 203 and a hook 205, the first upper connection housing 201 is mounted on the first lower connection housing 202, the nozzle 204 partially extends through the first lower connection housing 202, the first nozzle support 203 is used for mounting the air tube 105 on the nozzle 204, the hook 205 is rotatably mounted on the first lower connection housing 202, and a hook edge 205a of the hook 205 can be hooked on an edge of the exhaust cover 501.

The first upper connecting shell 201 and the first lower connecting shell 202 are arranged in a matching way to form a cavity for installing the suction nozzle 204 and the first suction nozzle bracket 203. The first nozzle holder 203 has a middle through pipe wall structure, one end of the air pipe 105 far away from the air pump 106 is mounted at one end of the middle through pipe wall of the first nozzle holder 203, the nozzle 204 is mounted at the other end of the middle through pipe wall of the first nozzle holder 203, and optionally, the first nozzle holder 203 is further fixed to the first lower connecting shell 202 by a screw or the like, so that one end of the air pipe 105 far away from the air pump 106 and the nozzle 204 are reliably mounted on the first nozzle holder 203.

One end of the first upper connecting shell 201 and one end of the first lower connecting shell 202 are rotatably mounted on the top of the main machine upper shell 101, and the other end of the first lower connecting shell 202 is used for mounting the hook 205. The first lower connecting shell 202 has a rotation shaft hole 202a, and the hook 205 is fitted to the rotation shaft hole 202a of the first lower connecting shell 202 through a rotation shaft 205b thereon to be mounted to the connecting mechanism 200. Also, the hook 205 is pivotable about the rotating shaft 205 b. Optionally, the connecting mechanism 200 further comprises a biasing spring 206, the biasing spring 206 is offset from the rotation axis 205b and is located between the hook 205 and the first connecting upper shell 201. The biasing spring 206 has a biasing function against both ends. The hook 205 has a hook edge 205a provided at a lower portion thereof and a hook edge arc end surface 205 c. When the connection mechanism 200 enters the working position, the hook-side arc end surface 205c of the hook side 205a abuts against the exhaust cover outer circle end surface 501h of the exhaust cover 501 and slides downwards to enable the hook side 205a to hook the exhaust cover outer circle lower end surface 501e, at this time, the suction nozzle 204 synchronously enters the working position, and the suction nozzle opening 204a is in fit connection with the exhaust nozzle 501 a.

Referring to fig. 13 to 15, the operation of the vacuum agitator 10 of the present embodiment is as follows:

after the container body 310 is mounted on the main body mechanism 100, the connecting mechanism 200 is rotated to the working position. At this time, the suction nozzle 204 of the link mechanism 200 is fitted to the outside of the exhaust nozzle 501a of the exhaust cover 501, and the nozzle opening sealing surface 204a1 is fitted to the outside of the exhaust opening sealing surface 501a 1. When the vacuum pump 106 evacuates the container body 310, the nozzle sealing surface 204a1 is in close contact with the exhaust port sealing surface 501a1 due to external back pressure. The gas in the container body 310 enters the circular space a2 through the container cover vent hole 401a, enters the circular space A3 through the gap between the upper inner ring rib 401c and the exhaust cover 501, enters the air pipe 105 closed cavity through the exhaust cover vent hole 501f of the exhaust cover 501, and is delivered to the air pump 106 through the air pipe 105.

When the vacuum degree in the container cavity a1 reaches a predetermined vacuum degree, the food material in the container body 310 is vacuum cut. After the vacuum cutting is completed, the attachment mechanism 200 needs to be removed. At this time, the hook 205 is pressed upward to urge the groove edge to come off the lower end surface 501e of the outer circle of the exhaust cover. When the link mechanism 200 is further lifted up, the nozzle opening sealing surface 204a1 is deformed by tensile force and slides along the exhaust opening sealing surface 501a1 of the exhaust cover 501 until it is separated, and then the nozzle 204 is separated from the exhaust cover 501 by its own elasticity. At the moment of disengagement, air enters the upper part of the one-way air valve 503 and covers the one-way air valve 503 to form external back pressure to drive the one-way air valve 503 to move downwards, the sealing surface 503a of the one-way air valve is tightly attached to the horizontal sealing surface 501b, the exhaust hole 501f of the exhaust cover is closed, the container sealed cavity A continues to maintain a vacuum state, and the connecting mechanism 200 with the suction nozzle 204 disengaged further returns to the open position due to the elastic force of the pivoting area.

Referring to fig. 3, 4, and 18 to 21, in an embodiment, the container cover 401 has a mounting hole and a container cover inlet hole 401b located on a peripheral side of the mounting hole, and the container cover inlet hole 401b communicates with the container cavity of the container body 310. The container cover 401 assembly further comprises a button 405 and a one-way air plug 404 capable of mounting the button 405, the one-way air plug 404 is mounted in the mounting hole, the one-way air plug 404 is made of an elastic material, and the edge of the one-way air plug 404 can move along with the button 405 to seal or open the air inlet hole 401b of the container cover.

When the container cavity a1 is in a vacuum state, the external back pressure urges the one-way air lock sealing surface 404a of the one-way air lock 404 against the container cover sealing surface 401e and the container cover air inlet hole 401b is closed. When the button 405 is pressed downward, the one-way air plug 404 is pressed downward to deform, so that the edge of the sealing surface 404a of the one-way air plug is tilted upward to expose the air inlet hole 401b of the container cover. At this point, air enters the container cavity from the external environment, and the button 405 is depressed until the vacuum in the container cavity a1 is removed, at which point the container lid 401 may be conveniently opened upward. The direction of the arrows shown in fig. 21 is the direction of the ambient air flow into the container cavity a 1. Releasing the button 405, the one-way air lock 404 rebounds to return to the original position along with the button 405.

Referring to fig. 1 to 4, in an embodiment, the host mechanism further includes a pressure sensor 107 and a controller 102, the pressure sensor 107 is disposed in the air pipe 105 and is used for detecting the pressure in the air pipe 105, and the pressure sensor 107 is further electrically connected to the controller 102 and is used for feeding back a pressure signal in the air pipe 105. One end of the air pipe 105 is connected with the air suction pump 106, the other end of the air pipe 105 is connected with a three-way joint, one outlet of the three-way joint is used for being connected with the suction nozzle 204, and the other outlet of the three-way joint is used for being connected with the pressure sensor 107. The pressure sensor 107 can thus detect the pressure of the gas in the gas pipe 105 and feed this pressure signal back to the controller 102, which monitors the pressure in the gas pipe 105 in real time by the controller 102. Furthermore, the controller 102 may be electrically connected to the air pump 106, so that the controller 102 can adjust the pressure in the air pipe 105 to adjust the vacuum degree of the container body 310 after vacuum is drawn.

Further, a nozzle spring 211 is disposed between the second nozzle holder 212 and the second upper case 210. The nozzle spring 211 is urged upward and downward to provide a biasing function to the second nozzle holder 212, thereby maintaining a downward force of the nozzle 204.

The upper part of the exhaust cover 501 is provided with an annular rib 504 matched with the annular groove 214a on the inner wall of the annular ring 214.
