To further clarify the technical solutions and effects adopted by the present application to achieve the intended purpose, the following detailed description is given with reference to the accompanying drawings and preferred embodiments according to the present application. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Referring to fig. 1-5, the food processor comprises a machine head 1, a food cup 2 detachably connected with the machine head 1, and a stirring assembly 3 driven by the machine head 1; the machine head 1 comprises a top cover 12 provided with a key hole 121, a key 12 positioned in the key hole 121, a shell 11 which forms a machine head inner cavity together with the top cover 12, a motor 13 arranged in the machine head inner cavity and a circuit board 14, wherein the motor 13 is connected with the stirring assembly 3 in a driving way, the circuit board 14 is electrically connected with the motor 13, and an electric switch key 141 positioned below the key 15 is arranged on the circuit board 14; a key sealing member 16 is disposed between the key 12 and the electrical switch key 141, and includes a sealing member body 161 abutting against the lower end of the hole wall of the key hole 121, a pressing contact portion 162 abutting against the electrical switch key 141, an elastic portion 163 connected between the sealing member body 161 and the pressing contact portion 162, and an elastic sealing edge 164 annularly disposed on the outer side surface of the elastic portion 163, and the elastic sealing edge 164 abuts against the hole wall of the key hole 121 to form a first sealing structure.

The utility model discloses a be equipped with button sealing member 16 between button 12 and electrical switch key 141, be in order to form sealedly to the aircraft nose inner chamber in button hole 121 department to prevent the gap of leaking that exists between the pore wall of button 12 and button hole 121, avoid outside liquid to leak into the aircraft nose inner chamber through button hole 121 in order to influence the work of motor 13 or/and circuit board 14.

Specifically, the elastic portion 163 includes an elastic straight tube 1631 extending upward from the sealing member body 161 and an elastic fold surface 1632 connected between the elastic straight tube 1631 and the pressing contact portion 162, and the elastic sealing edge 164 is disposed around an outer side surface of the elastic straight tube 1631.

The elastic straight tube 1631 generates circumferential elasticity to the hole wall of the key hole 121 to ensure that the elastic sealing edge 164 can be always abutted against the hole wall of the key hole 121, and a first sealing structure is formed by the elastic sealing edge 164 for a gap between the key 12 and the hole wall of the key hole 121. To improve the reliability of the elastomeric seal 164, at least 2 rings of elastomeric seal 164 may be optionally provided to improve sealing performance.

The elastic pleat 1632 provides the pressing contact portion 162 to move up and down relative to the sealing member body 161 mainly by generating elastic deformation, so that the sealing relationship formed by the abutting between the elastic sealing edge 164 and the hole wall of the key hole 121 is not destroyed when the pressing contact portion 162 moves up and down during the operation of the key 12. When the key 12 is pressed, the pressing contact portion 162 is pushed to be pressed synchronously, and the electrical switch key 141 is triggered to perform electrical switching, so as to implement the operation of turning on or off the food processor.

The seal body 161 has a stepped portion 1611 on an upper end surface thereof, and the stepped portion 1611 has a first sealing surface on an upper end surface thereof. The lower end surface of the hole wall of key hole 121 abuts against the first sealing surface of step 1611, and forms a second sealing structure for the gap between key 12 and the hole wall of key hole 121. Therefore, even if the elastic sealing edge 164 fails in the long-term use process, liquid enters the key hole 121, and the liquid cannot further leak into the inner cavity of the handpiece under the action of the second sealing structure.

To improve the reliability of the second seal structure, for this reason, a fixing bracket 17 is fixedly provided in the head cavity, the circuit board 14 is fixed on the fixing bracket 17, and the lower end of the seal member body 161 is supported on the fixing bracket 17 or the circuit board 14. The key sealing piece 16 is directly or indirectly supported by the fixing support 17, so that the lower end faces of the sealing piece body 161 and the hole wall of the key hole 121 can be always kept in a butting sealing relationship to enable the key sealing piece 16 to seal and block the key hole 121 from the lower part of the key hole 121, and the sealing performance is improved.

The fixed support 17 is provided with a motor mounting groove 171, the motor 13 is vertically assembled in the inner cavity of the machine head, and the upper end of the motor 13 is accommodated in the motor mounting groove 171, so that the fixed support 17 can play a role in fixedly assembling the motor 13 in the inner cavity of the machine head. For example, the fixing bracket 17 is provided with a plurality of screw holes, the inner wall of the housing 11 is correspondingly provided with a plurality of studs, and screws are screwed into the corresponding studs through the screw holes to fixedly assemble the fixing bracket 17 and the inner wall of the housing 11.

A motor mounting seat 111 is provided at a bottom side of the housing 11, a fixing bracket 17 is positioned above the motor mounting seat 111, and the motor 13 is assembled between the motor mounting seat 111 and the fixing bracket 17. During the assembly, place motor 13's lower terminal spacing earlier in motor mount pad 111, establish fixed bolster 17 cover again and make motor 13's last end hold in motor mounting groove 171 on motor 13 in, it can to fix fixed bolster 17 and shell 11 through current fixed knot structures such as screw, double-screw bolt for motor 13's assembly easy operation when producing the cooking machine.

The food processor is embodied as a soybean milk machine, a stirrer or a wall breaking machine and the like. In the embodiment shown in the drawings of the application, the cooking cup 2 is detachably assembled below the machine head 1, and essentially forms a cup type stirrer or a cup type cooking machine.

For convenience of movement or carrying, a rechargeable battery 19 is also typically provided in the interior cavity of the handpiece. In one embodiment, the fixing bracket 17 further includes a battery mounting bracket 172, the battery mounting bracket 172 is engaged with the inner wall of the housing 11 to define a battery mounting space in the inner cavity of the handpiece, and the rechargeable battery 19 is located in the battery mounting space. Therefore, the fixing bracket 17 also functions to fix the rechargeable battery 19.
