Low-noise food processor

Abstract

The invention discloses a low-noise food processor. The low-noise food processor comprises a base and a stirring cup arranged on the base, a motor and a circuit board are arranged in the base; the stirring cup comprises a cup body and a cup cover; a crushing cutter is arranged in cup body, a motor drives the crushing cutter, the cup cover comprises an upper cover and a lower cover; the lower covercomprises a lower cover top wall, a lower cover side wall and a sealing ring; at least part of the side wall of the lower cover extends into the cup body, the sealing ring is arranged between the side wall of the lower cover and the cup body, a through hole is formed in the top wall of the lower cover, an upward surrounding edge is arranged on the edge of the top wall of the lower cover, the upper cover covers the surrounding edge, and a silencing cavity is defined between the upper cover and the lower cover and communicated with the outside through an exhaust gap which is arranged at the upper cover. After noise generated in the cup body enters the silencing cavity from the through hole, the noise pressure is released and attenuated, and then the noise is further attenuated through the exhaust gap and discharged, so that the discharged noise is greatly attenuated, and the noise is greatly reduced.

Description

technical field [0001] The invention belongs to the field of food processing machines, in particular to a low-noise food processing machine. Background technique [0002] Existing food processing machines usually include a machine base and a stirring cup. A circuit board and a motor are arranged in the machine base. The stirring cup includes a cup body and a cup cover. , the circuit board controls the motor to drive the pulverizer to rotate to realize the pulverization of the ingredients in the pulverization chamber. It is not easy to open. There is usually an air outlet connected to the outside world between the feeding cover and the feeding hole. However, during the pulverization process, the pulverizer will cut the food and produce noise, so that the noise will be transmitted outward through the air outlet of the cup lid, causing food The processing machine has the problem of high noise during use, which affects the user experience. [0003] In order to solve the above ...

The stirring cup includes a cup body and a cup cover. , the circuit board controls the motor to drive the pulverizer to rotate to realize the pulverization of the ingredients in the pulverization chamber. It is not easy to open. There is usually an air outlet connected to the outside world between the feeding cover and the feeding hole. However, during the pulverization process, the pulverizer will cut the food and produce noise, so that the noise will be transmitted outward through the air outlet of the cup lid, causing food There is a problem of high noise when the processing machine is in use, which affects the user experience

[0003] In order to solve the above problems, the structure of the feeding cover is often improved in the prior art, and a sound-absorbing structure is added in the feeding cover to reduce the noise in advance. However, this noise reduction scheme makes the structure of the feeding cover more complicated. At the same time, the small space of the feeding cover also limits its poor noise reduction effect, and the complex structure also brings the problem that the feeding cover is not easy to clean
