Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine with stable operation. Background Art

[0002] Existing wall-breaking machines such as soymilk machines and wall-breaking machines usually include a machine base, a detachable cup body with a crushing chamber installed on the machine base, a crushing device installed in the crushing chamber, and a motor assembly installed under the cup body and connected to the crushing device. When users use the food processor, they put the food in the cup body assembly, and the motor assembly rotates at high speed and drives the crushing device to rotate to process the food. Although this type of machine can replace different cup bodies to process different ingredients, its cup body is exposed to the outside world, and the crushing device will produce a lot of noise when cutting the food, which is not a good user experience. There is also a food processor that does not require hand washing. For example, Chinese utility model patent CN212879008U discloses a food processor with a stable grinding cup body for taking and placing, including a body with an installation cavity, the cup body is detachably arranged in the installation cavity, and the motor is fixedly installed in the body. Although this model can also replace different cup bodies, the body will still generate a lot of noise when it rotates at high speed and the grinding device cuts the food, and most of the noise will pass through the gap between the installation cavity and the cup body to the outside. At the same time, the installation cavity has a poor effect of limiting the cup body. When the cup body rotates, it will increase the vibration and collide with the inner wall of the installation cavity. Noise, seriously affecting the consumer experience. Utility Model Content

[0003] The utility model aims to provide a food processing machine with stable operation, in which the cup body is detachable relative to the machine body to realize multi-functions and the working noise of the food processing machine can be reduced at the same time.

[0004] To achieve the above-mentioned purpose, the utility model provides a food processing machine with stable operation, including a machine body, a cup body assembly arranged on the machine body and having a grinding chamber, the machine body is formed with a mounting chamber, the cup body assembly is detachably arranged in the mounting chamber, the cup body assembly includes a grinding cup and an inner cover covering the cup mouth of the grinding cup, the machine body is also hinged with an outer cover, the outer cover covers the top opening of the mounting chamber, and the bottom end of the outer cover is pressed onto the inner cover, the inner cover is provided with a first exhaust hole, and the outer cover is provided with a second exhaust hole connected to the first exhaust hole.

[0005] The present application sets the cup body assembly to be detachably installed in the installation cavity, so that users can replace different cup body assemblies according to different usage requirements, such as a crushing cup, a dry grinding cup, and a minced meat cup, so as to process different ingredients, thereby improving the user experience. In addition, the installation cavity can play a certain positioning role for the cup body assembly. The installation cavity can limit the cup body assembly circumferentially to ensure the stability of the position of the cup body assembly in the installation cavity, avoid the cup body assembly from shaking significantly, thereby further reducing the noise generated by the shaking of the cup body, and is beneficial to the stability of the cup body during the operation of the food processing part. In addition, the cup body assembly is located in the installation cavity, and the noise generated in the cup body assembly can be repeatedly rebounded in the installation cavity, thereby greatly reducing the energy of the noise, and then reducing the volume of the noise propagating outward, which helps to improve the noise reduction effect.

[0006] At the same time, the cup body assembly includes a crushing cup and an inner cover that covers the mouth of the crushing cup, so that the noise generated by the cup body assembly when processing food can be reduced by the inner cover, and the noise after noise reduction can be further reduced by the outer cover, thereby achieving double noise reduction, which helps to further improve the noise reduction effect. The inner cover covers the mouth of the crushing cup, on the one hand, to prevent the material in the crushing cup from splashing to the outside to cause cleaning burden, and on the other hand, to protect the inside of the crushing cup to prevent external dust from entering and contaminating the internal material, thereby further improving the performance of the food processing machine. The bottom end of the outer cover is crimped on the top of the inner cover, so that the outer cover can be closed to the installation cavity after the cover is closed, and then the cup body assembly is closed in the installation cavity, so as to achieve axial limitation of the cup body assembly, so that the positioning effect of the cup body assembly in the installation cavity is further achieved after the cover is closed, which is conducive to maintaining the stability of the cup body assembly during the processing process, avoiding the shaking of the cup body assembly, and further reducing the knock noise caused by the shaking of the cup body assembly. In addition, the inner cover is provided with a first exhaust hole, and the outer cover is provided with a second exhaust hole connected to the first exhaust hole, so that when the food processor is processing food, the gas generated in the grinding chamber can be discharged to the outside through the first exhaust hole and the second exhaust hole, effectively avoiding the situation where the internal pressure continues to increase due to excessive gas in the grinding chamber, causing the inner cover to be pushed open, thereby ensuring the smooth processing of food.

[0007] In a preferred implementation of a food processor with stable operation, the outer cover is pressed onto the top end of the inner cover by a flexible member.

[0012] By providing a ventilation plug in the first exhaust hole and / or the second exhaust hole, when the food processor is processing food, if there is a lot of food in the grinding chamber and it overflows upward, the food can be blocked by the ventilation plug, which effectively avoids the occurrence of overflow. While achieving ventilation, overflow is avoided, and the working stability of the whole machine is further improved.
