Description

Sealing assembly and food processor

Technical Field

The invention relates to the field of small household appliances, in particular to a sealing assembly and a food processor.

Background

With the increasing living standard of people, many different types of food processors appear on the market. The functions of the food processor mainly include, but are not limited to, functions of making soybean milk, squeezing fruit juice, making rice paste, mincing meat, shaving ice, making coffee and/or blending facial masks and the like. The food processor can comprise a soybean milk machine, a stirrer or a wall breaking food processor and other machines for crushing and stirring food. The food processor can vacuumize the space in the stirring cup assembly, and can keep food fresh and resist oxidation. Before the cup cover assembly is taken down from the stirring cup assembly, the negative pressure state in the cup needs to be relieved, and the cup cover assembly can be opened after the air is exhausted. However, the existing food processor needs to cover the center of the cup body well and then vacuumize, and if a consumer does not pack the food or has food stuck in the center cover, the vacuumize and vacuum pressure maintaining are ineffective, so that the food cannot achieve the fresh-keeping effect.

Referring to fig. 1 to 11, in the illustrated embodiment, the food processor may be a soymilk maker, a juice extractor, a wall breaking machine, or the like. The food processor comprises a cup seat assembly (not shown), a cup body assembly 1 and a cup cover assembly 2.

The cup holder assembly is in the form of a stand provided with a motor (not shown). A stirring knife assembly 13 is arranged in the cup body assembly 1. The motor drives the stirring blade assembly 13 to rotate to stir the food material. The invention is not limited to the above, and the stirring blade assembly 13 can also be arranged on the cup cover assembly 2, and when in use, the stirring blade assembly extends into the cup body assembly 1 to stir the food material. A control circuit board (not shown) is also installed in the cup holder assembly for providing power and control signals to control the operation of the food processor.

Referring now to FIGS. 1-7, the lid assembly 2 is shown removably mounted to the bowl assembly 1. The cap assembly 2 comprises a cap 21, and a sealing assembly, a pull rod 23 and an elastic element 24 which are arranged on the cap 21. The cap 21 includes a main body 210, a through hole 211 and an accommodating hole 212 penetrating the main body 210, a first abutting block 214 extending from the main body 210, a guide block 215, a pair of stop blocks 216 and a pair of slide blocks 217. The guide block 215 and the pair of stoppers 216 are disposed near the through hole 211. The first abutting block 214 is located between the pair of sliding blocks 217.

The seal assembly passes through the through hole 211 and is positioned on the cap 21. The sealing assembly includes an exhaust valve 220, an exhaust cover 221 and a button 222 assembled to the exhaust valve 220, a first sealing ring 223 positioned between the exhaust valve 220 and the cup cover 21, a second sealing ring 224 positioned between the exhaust valve 220 and the exhaust cover 221, a sealing ring 25 positioned on the button 222, and a second elastic member (not shown). The exhaust valve 220 includes a first intake hole 2201, a second intake hole 2202, a suction hole 2203, a recess 2204 communicating with the suction hole 2203, and an outlet hole 2205 communicating with the recess 2204. The air outlet hole 2205 and the first air inlet hole 2201 are communicated with the outside, and the second air inlet hole 2202 is communicated with the space in the cup body assembly 1. The suction hole 2203 is connected to a vacuum pump (not shown) through a suction pipe (not shown) for evacuating the cup assembly 1. The air outlet 2205 is communicated with the outside, so that air in the cup body assembly 1 enters the air suction hole 2203 through a vacuum pump and is discharged to an external space from the recess 2204 and the air outlet 2205. A one-way valve (not shown) is arranged in the air exhaust pipe to prevent outside air from entering the cup body assembly 1 through the air exhaust pipe. The button 222 includes a pressing portion 2220, an extending portion 2223 extending downward from the pressing portion 2220, a pair of protruding portions 2221 extending to one side from the pressing portion 2220, and a pair of positioning posts 2222. The sealing ring 25 is located on the extending portion 2223, and the extending portion 2223 passes through the first air inlet hole 2201. Referring to fig. 9 to 10, when the button 222 is not pressed, the sealing ring 25 seals the first air inlet 2201, so that the cup body assembly 1 is sealed, and at this time, vacuum pumping can be performed; when the button 222 is pressed downwards, the sealing ring 25 moves downwards to open the first air inlet hole 2201, so that outside air enters the cup body assembly 1 through the first air inlet hole 2201 and the second air inlet hole 2202, the pressure of the cup body assembly 1 is relieved, and the cup lid assembly 2 can be opened normally. The elastic force of the second elastic member after being compressed causes the button 222 to be sprung upward. The positioning post 2222 abuts against the cup cover 21 to prevent the button 222 from separating from the cup cover 21 when bouncing upwards.

The pull rod 23 includes a second abutting block 231, a boss 232, a pair of crimping portions 233 and a pair of recesses 234. The two opposite ends of the elastic element 24 respectively abut against the first abutting block 214 and the second abutting block 231. The elastic force of the elastic member 24 after being compressed pushes the pull rod 23 to move. When the pull rod 23 is assembled to the cap 21, the boss 232 passes through the receiving hole 212 of the cap 21 and can move along the receiving hole 212. The height of the boss 232 is 3 mm-10 mm. The pair of crimping portions 233 are used to crimp the pair of projections 2221 of the button 222, so that the button 222 is held in a depressed state. The pair of crimping portions 233 are located below the pair of stoppers 216 of the lid 21 to prevent the pull rod 23 from being separated upward from the lid 21. The pair of sliding blocks 217 of the cap 21 are located in the pair of grooves 234 of the pull rod 23, and the guide block 215 is located between the pair of crimping portions 233, so that smooth horizontal movement of the pull rod 23 is effectively ensured. In this embodiment, the sliding block 217 is disposed on the cup cover 21, and the groove 234 is disposed on the pull rod 23, but the present application is not limited thereto, and the sliding block 217 may be disposed on the pull rod 23, and the groove 234 is correspondingly disposed on the cup cover 21.
