In addition, there is also a food processor that does not need to be washed by hand, such as the Chinese utility model patent CN212879008U, which discloses a food processor with a stable crushing cup body, including a machine body with an internal mounting chamber, the cup body is detachably provided in the mounting chamber, and the motor is fixedly installed in the machine body. Although this type of machine can also replace different cup bodies, the machine body still generates a large noise when rotating at high speed and the crushing device cuts the food materials, and most of the noise will pass through the gap between the mounting chamber and the cup body to the outside world, seriously affecting the consumer's experience. Utility Model Content

[0003] The utility model aims to provide a food processing machine with good noise reduction effect, 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 good noise reduction effect, including a machine body, a cup body assembly arranged in the machine body and having a grinding chamber, a grinding device arranged in the grinding chamber, and a motor assembly arranged below the cup body assembly and transmission connected to the grinding device. The machine body is formed with an installation cavity, the cup body assembly includes a plurality of cup bodies, and one of the plurality of cup bodies is detachably arranged in the installation cavity, and the machine body is also hinged with a cover body, which can cover the top opening of the installation cavity to seal the cup body in the installation cavity.

[0005] The present application is configured to include a plurality of cup bodies through a cup body assembly, and one of the plurality of cup bodies is detachably arranged in the installation cavity, so that users can replace different cup bodies according to different usage requirements, such as a crushing cup, a dry grinding cup, and a minced meat cup, etc., so as to process different ingredients, thereby improving the user experience. In addition, the installation cavity can play a certain positioning role on the cup body, ensure the stability of the position of the cup body in the installation cavity, and avoid the situation where the cup body shakes greatly, 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. At the same time, the cover body is covered on the opening at the top of the installation cavity, so that the installation cavity can be closed after the cover body is closed, and then the cup body is closed in the installation cavity. On the one hand, when the food processor is processing food, both the noise generated by the cup body crushing the food and the noise generated by the motor assembly in the machine body can be blocked in the installation cavity, avoiding the noise from directly propagating outward through the opening at the top of the installation cavity, which helps to further improve the noise reduction effect, thereby achieving the cup body assembly being detachable relative to the machine body while also being able to significantly reduce the working noise, satisfying the consumer's quiet use experience; on the other hand, the cup body is hidden and installed, which realizes the protection of the cup body, avoiding the cup body from direct contact with the outside world, causing external dust to fly into the installation cavity or even the cup body, causing the food to be contaminated, and ensuring the consistency of the appearance of the whole machine, especially the food processor that does not need to be washed by hand, thereby improving the user experience.

[0006] In a preferred implementation of a food processor with good noise reduction effect, the cup body assembly includes a first cup body and a second cup body, and the crushing devices in the first cup body and the second cup body are adapted to a first rotational speed and a second rotational speed respectively.

[0007] By configuring the cup body assembly to include a first cup body and a second cup body, the crushing devices in the first cup body and the second cup body are adapted to the first rotation speed and the second rotation speed respectively, so that after the first cup body or the second cup body is installed in the installation cavity, the crushing devices in different cup bodies have different rotation speeds, that is: the crushing device in the first cup body has a first rotation speed, and the crushing device in the second cup body has a second rotation speed. When the first cup body requires high speed and low torque, such as a waste crushing cup, the first speed is higher and the torque is lower to achieve high-speed crushing of the food, thereby ensuring the crushing effect of the food; when the second cup body requires low speed and high torque, such as a dry grinding cup, the second speed is lower and the torque is larger to achieve effective grinding of the food, thereby ensuring that the food processor can adapt to different cup bodies to achieve processing of different food ingredients, thereby improving user experience.

[0008] In a preferred implementation of a food processor with good noise reduction effect, a speed change mechanism is provided at the bottom of the first cup body and / or the second cup body, and one end of the speed change mechanism is transmission connected to the crushing device, and the other end is transmission connected to the motor assembly.

[0009] By providing a speed changing mechanism at the bottom end of the first cup body and / or the second cup body, and one end of the speed changing mechanism is transmission connected to the crushing device, and the other end is transmission connected to the motor assembly, when the speed changing mechanism is provided at the bottom end of the first cup body or the second cup body, after the torque output by the motor assembly is transmitted to the speed changing mechanism, the speed changing mechanism is accelerated or decelerated to transmit the speed-changed torque to the crushing device, thereby achieving different rotation speeds of the crushing devices in different cup bodies.

[0010] In a preferred implementation of a food processor with good noise reduction effect, the motor assembly includes a variable frequency motor, and the variable frequency motor can output a first rotation speed and a second rotation speed.

[0011] By configuring the motor assembly to include a variable frequency motor, and the variable frequency motor can output a first speed and a second speed, the structural components are omitted to achieve outputs at different speeds, which helps to improve the compactness of the entire machine structure, while also reducing production costs and the weight of the entire machine, making it easier for users to take and put the food processor. At the same time, the variable frequency motor can achieve outputs at different speeds according to different cup bodies, and more preferably, can also achieve outputs at different speeds according to different ingredients, further improving the effect of ingredient processing.

[0012] In a preferred implementation of a food processor with good noise reduction effect, the bottom end of the cover body abuts against the top end of the cup body.

[0013] By setting the bottom end of the cover body to abut against the top end of the cup body, the compactness of the overall assembly is enhanced, and the cover body abuts against the top end of the cup body after being closed, cooperating with the installation cavity to achieve axial limitation of the cup body, thereby further achieving the positioning effect of the cup body in the installation cavity after the cover body is closed, which is beneficial to maintaining the stability of the cup body during the processing and avoiding shaking of the cup body, thereby further reducing the knocking noise caused by the shaking of the cup body.

[0014] In a preferred implementation of a food processor with good noise reduction effect, the cover body is pressed onto the top of the cup body through a flexible member.

[0015] By setting a flexible part to be pressed against the top of the cup body, the axial limiting effect of the cup body is achieved when the cover is closed, and the cup body is in flexible contact with the cover body when it shakes, effectively avoiding the cup body and the cover body from colliding with each other and generating vibration noise. At the same time, the top of the cup body is further isolated from the outside world by the flexible part, so that the noise transmitted from the cup body is further reduced under the isolation effect of the flexible part, which helps to further improve the noise reduction effect. The setting of the flexible part can avoid the collision between the bottom wall of the cover body and the top wall of the cup body when the cover is closed with great force, further strengthening the protection effect of the cover body and the cup body, and reducing the collision noise generated when the cover is closed, improving the user experience.

[0016] In a preferred implementation of a food processor with good noise reduction effect, the cup body assembly includes a grinding cup and a cup cover covering the mouth of the grinding cup.

[0017] By configuring the cup body assembly to include a grinding cup and a cup cover covering the grinding cup, the noise generated by the cup body when processing food can be reduced by the cup 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 cup cover covers the mouth of the grinding cup, which, on the one hand, prevents the material in the grinding cup from splashing to the outside and causing a cleaning burden, and on the other hand, protects the inside of the grinding cup to prevent external dust from entering and contaminating the internal material, thereby further improving the performance of the food processor.

[0018] In a preferred implementation of a food processor with good noise reduction effect, the motor assembly can rotate forward and reverse to drive the grinding device to have a first rotation direction and a second rotation direction opposite to the first rotation direction.

[0019] By setting the motor assembly to be able to rotate forward and reverse, the crushing device can be driven to have a first rotation direction and a second rotation direction opposite to the first rotation direction, so that the crushing device can achieve cutting and crushing of food in different directions through different rotation directions, which helps to improve the crushing effect, and at the same time can improve the crushing efficiency and shorten the food processing time.

[0020] In a preferred implementation of a food processor with good noise reduction effect, the crushing device is provided with a first blade and a second blade, the first blade is provided in front of the first rotation direction, and the second blade is provided in front of the second rotation direction.

[0021] By providing the crushing device with a first blade and a second blade, the first blade is arranged in front of the first rotation direction, and the second blade is arranged in front of the second rotation direction, the crushing device can process the food through different blades when it rotates in different directions. For example, when performing initial processing on the food, the motor assembly drives the crushing device to rotate along the first rotation direction, and the first blade performs preliminary crushing of the food; after a period of preliminary crushing, the motor assembly drives the crushing device to rotate along the second rotation direction, and the second blade performs further fine crushing of the food, thereby ensuring the food crushing effect and helping to further improve the food processing efficiency.

[0022] In a preferred implementation of a food processor with good noise reduction effect, a concave groove is provided on the top of the machine body, a fixing piece is fixed in the groove, the fixing piece is provided with an upwardly protruding hinge, and the rotating shaft of the cover body is inserted into the hinge.

[0023] The positioning of the cover body on the top of the body is achieved by providing grooves and fixing parts. At the same time, the fixing part is provided with an upwardly protruding hinge part which cooperates with the rotating shaft of the cover body to achieve a hinged limiting effect of the cover body. On the one hand, a simple installation structure can be used to ensure that the cover body is stably fixed on the top of the body to prevent the cover body from being separated from the body. On the other hand, the hinge part and the rotating shaft can be used to realize the rotation of the cover body around the rotating shaft, thereby realizing the locking and disengagement between the cover body and the cup body, and realizing the protection and noise reduction effects of the cup body when the cover body is locked with the cup body. When the cover body is separated from the cup body, it is convenient to take the cup body out of the installation cavity without removing the cover body from the body, thereby simplifying the user's use steps and improving the user experience.

The machine body 1 is formed with a mounting chamber 11, the cup body assembly 2 includes a plurality of cup bodies 2, and the plurality of cup bodies 2 are selectively detachably arranged in the mounting chamber 11, and the machine body 1 is also hinged with a cover body 5, which can cover the top opening of the mounting chamber 11 to seal the cup body 2 in the mounting chamber 11.

[0036] The present application is configured to include a plurality of cup bodies 2 through the cup body assembly 2, and one of the plurality of cup bodies 2 is detachably arranged in the installation cavity 11, so that the user can replace different cup bodies 2 according to different usage requirements, such as a crushing cup, a dry grinding cup, and a minced meat cup, etc., so as to process different ingredients, thereby improving the user experience. In addition, the installation cavity 11 can play a certain positioning role for the cup body 2, ensure the stability of the position of the cup body 2 in the installation cavity 11, and avoid the situation where the cup body 2 shakes greatly, thereby further reducing the noise generated by the shaking of the cup body 2, and is beneficial to the stability of the cup body 2 during the working process of the food processing part. In addition, the cup body assembly 2 is located in the installation cavity 11, and the noise generated in the cup body assembly 2 can be repeatedly rebounded in the installation cavity 11, 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. At the same time, the cover body 5 covers the open top of the installation cavity 11, so that the installation cavity 11 is closed after the cover body 5 is closed, and the cup body 2 is enclosed in the installation cavity 11. On the one hand, when the food processor is processing food, both the noise generated by the cup body 2 crushing the food and the noise generated by the motor assembly 4 in the body 1 can be blocked in the installation cavity 11, avoiding the noise from directly propagating outward through the open top of the installation cavity 11, which helps to further improve the noise reduction effect, thereby achieving the cup body assembly 2 being detachable relative to the body 1 while also significantly reducing the working noise, satisfying the consumer's quiet use experience; on the other hand, the hidden installation of the cup body 2 is achieved, and the protection of the cup body 2 is achieved, avoiding the cup body 2 from directly contacting the outside world, causing external dust to fly into the installation cavity 11 or even the cup body 2, causing the food to be contaminated, and ensuring the consistency of the appearance of the whole machine, especially the food processor that does not need to be washed by hand, thereby improving the user experience.

[0037] As a preferred embodiment of the present application, Figure 1 , Figure 4 , Figure 5 As shown, the cup body assembly 2 includes a first cup body 22 and a second cup body 23, and the crushing devices 3 in the first cup body 22 and the second cup body 23 are adapted to a first rotation speed and a second rotation speed respectively.

[0038] By setting the cup body assembly 2 as the cup body 2 including the first cup body 22 and the second cup body 23, the crushing devices 3 in the first cup body 22 and the second cup body 23 are adapted to the first rotation speed and the second rotation speed respectively, so that after the first cup body 22 or the second cup body 23 is installed in the installation cavity 11, the crushing devices 3 in different cup bodies 2 have different rotation speeds, that is: the crushing device 3 in the first cup body 22 has a first rotation speed, and the crushing device 3 in the second cup body 23 has a second rotation speed. When the first cup body 22 requires high speed and low torque, such as a waste crushing cup, the first speed is higher and the torque is smaller to achieve high-speed crushing of food materials, thereby ensuring the crushing effect of the food materials; when the second cup body 23 requires low speed and high torque, such as a dry grinding cup, the second speed is lower and the torque is larger to achieve effective grinding of food materials, thereby ensuring that the food processor can adapt to different cup bodies 2 to achieve processing of different food materials, thereby improving user experience.

[0039] Of course, the cup body assembly 2 in the present application is not limited to the first cup body 22 and the second cup body 23, and it can also include more cup bodies 2 to realize the processing of different ingredients, and the crushing devices 3 in different cup bodies 2 are adapted to different rotation speeds.

[0040] It should be noted that the present application does not specifically limit the output mode of the first speed and the second speed, which can be any one of the following embodiments:

[0041] Embodiment 1: In this embodiment, a speed change mechanism 7 is provided at the bottom of the first cup body 22 and / or the second cup body 23, and one end of the speed change mechanism 7 is transmission-connected to the crushing device 3, and the other end is transmission-connected to the motor assembly 4. Preferably, Figure 5 As shown, a speed change mechanism 7 is disposed in the second cup body 23 . Specifically, the speed change mechanism 7 is a speed change gear box. The torque of the motor assembly 4 is transmitted to the gear box and then decelerated in the gear box and output to the crushing device 3 .

[0042] By providing a speed changing mechanism 7 at the bottom end of the first cup body 22 and / or the second cup body 23, and one end of the speed changing mechanism 7 is transmission connected to the crushing device 3, and the other end is transmission connected to the motor assembly 4, when the speed changing mechanism 7 is provided at the bottom end of the first cup body 22 or the second cup body 23, after the torque output by the motor assembly 4 is transmitted to the speed changing mechanism 7, the speed changing mechanism 7 is accelerated or decelerated to transmit the speed-changed torque to the crushing device 3, thereby achieving different rotation speeds of the crushing device 3 in different cup bodies 2.

[0043] Embodiment 2: In this embodiment, the motor assembly 4 includes a variable frequency motor, and the variable frequency motor can output a first rotation speed and a second rotation speed.

[0044] By configuring the motor assembly 4 to include a variable frequency motor, and the variable frequency motor can output a first speed and a second speed, the structural components are omitted to achieve outputs at different speeds, which helps to improve the compactness of the entire machine structure, while also reducing production costs, reducing the weight of the entire machine, and making it easier for users to take and put the food processor. At the same time, the variable frequency motor can achieve outputs at different speeds according to different cup bodies 2, and more preferably, can also achieve outputs at different speeds according to different ingredients, further improving the effect of ingredient processing.

[0046] By setting the bottom end of the cover body 5 to abut against the top end of the cup body 2, the compactness of the overall assembly is enhanced, and the cover body 5 abuts against the top end of the cup body 2 after being closed, cooperating with the installation cavity 11 to achieve axial limitation of the cup body 2, thereby further achieving the positioning effect of the cup body 2 in the installation cavity 11 after the cover body 5 is closed, which is beneficial to maintaining the stability of the cup body 2 during the processing and avoiding the shaking of the cup body 2, thereby further reducing the knocking noise caused by the shaking of the cup body 2.

[0047] As a preferred embodiment of the present application, Figure 2 As shown, the cover body 5 is pressed onto the top end of the cup body 2 through the flexible member 8 .

[0048] By setting the flexible member 8 to be pressed against the top of the cup body 2, the axial limiting effect of the cup body 2 is achieved when the cover body 5 is closed, and the cup body 2 is in flexible contact with the cover body 5 when shaking, effectively avoiding the situation where the cup body 2 and the cover body 5 collide with each other and generate vibration noise. At the same time, the top of the cup body 2 is further isolated from the outside world by the flexible member 8, so that the noise transmitted from the cup body 2 is further reduced under the isolation effect of the flexible member 8, which helps to further improve the noise reduction effect. In addition, the setting of the flexible member 8 prevents the bottom wall of the cover body 5 from colliding with the top wall of the cup body 2 when a large force is applied when the cover body 5 is closed, further strengthening the protection effect of the cover body 5 and the cup body 2, and reducing the collision noise generated when the cover body 5 is closed, improving the user experience.

[0049] Furthermore, if Figure 2 As shown, the cup body assembly 2 includes a grinding cup and a cup cover covering the mouth of the grinding cup.

[0050] By configuring the cup body assembly 2 to include a grinding cup and a cup cover covering the grinding cup, the noise generated by the cup body 2 when processing food can be reduced by the cup 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 cup cover covers the mouth of the grinding cup, which, on the one hand, prevents the material in the grinding cup from splashing to the outside and causing a cleaning burden, and on the other hand, protects the inside of the grinding cup to prevent external dust from entering and contaminating the internal material, thereby further improving the performance of the food processor.

[0051] As a preferred embodiment of the present application, the motor assembly 4 can rotate forward and reversely to drive the crushing device 3 to have a first rotation direction and a second rotation direction opposite to the first rotation direction.

[0052] By setting the motor assembly 4 to be able to rotate forward and reverse, the crushing device 3 is driven to have a first rotation direction and a second rotation direction opposite to the first rotation direction, so that the crushing device 3 can achieve cutting and crushing of food in different directions through different rotation directions, which helps to improve the crushing effect, and at the same time can improve the crushing efficiency and shorten the food processing time.

[0053] Furthermore, if Figure 6 As shown, the pulverizing device 3 is provided with a first blade 31 and a second blade 32 , wherein the first blade 31 is provided in front of the first rotation direction, and the second blade 32 is provided in front of the second rotation direction.

[0054] By providing the crushing device 3 with a first blade 31 and a second blade 32, the first blade 31 is arranged in front of the first rotation direction, and the second blade 32 is arranged in front of the second rotation direction, the crushing device 3 can process the food through different blades when it rotates in different directions. For example, when performing initial processing on the food, the motor component 4 drives the crushing device 3 to rotate along the first rotation direction, and the first blade 31 is used to perform preliminary crushing of the food; after a period of preliminary crushing, the motor component 4 drives the crushing device 3 to rotate along the second rotation direction, and the second blade 32 is used to further finely crush the food, thereby ensuring the food crushing effect and helping to further improve the food processing efficiency.

At the same time, the fixing member 6 is provided with an upwardly protruding hinge portion 61 that cooperates with the rotating shaft of the cover body 5 to achieve a hinged limiting effect of the cover body 5. On the one hand, a simple installation structure can be used to ensure that the cover body 5 is stably fixed on the top of the body 1 to prevent the cover body 5 from being separated from the body 1. On the other hand, the hinge portion 61 and the rotating shaft can be used to realize the rotation of the cover body 5 around the rotating shaft, thereby realizing the locking and disengagement between the cover body 5 and the cup body 2, and realizing the protection and noise reduction effects of the cup body 2 when the cover body 5 is locked with the cup body 2. When the cover body 5 is separated from the cup body 2, it is convenient to take the cup body 2 out of the installation cavity 11, and there is no need to remove the cover body 5 from the body 1, thereby simplifying the user's use steps and improving the user's use experience.
