Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with good noise reduction effect. Background Technology

[0002] Existing food processors, such as soy milk makers, typically include a main unit with a built-in motor and a detachable cup assembly located above the main unit, containing a built-in mixing element. After the cup assembly is placed on the main unit, the mixing element is connected to the motor. When the user uses the food processor, the motor drives the mixing element to rotate at high speed to pulverize the ingredients. However, this process generates significant noise. Some of this noise is due to the collision of ingredients as they are pulverized, while other noise is generated by the upper connector connected to the mixing element and the lower connector connected to the motor shaft transmitting torque. To reduce noise propagation, Chinese invention patent CN118986163A discloses a food processor with a recessed groove at the top of the base (main unit). A second positioning part is located within the recessed groove, and the cup is installed within it. The cup is positioned against the base by the second positioning part, and a soundproof cover is installed on the outside of the cup. The recessed groove and the soundproof cover work together to reduce noise throughout the entire food processor. However, users have found that during actual use, there is still a significant amount of noise transmitted to the outside world, especially from the upper and lower connectors, which seriously affects the user experience. How to further reduce the noise generated by the torque transmission of the upper and lower connectors is a technical problem that urgently needs to be solved. Utility Model Content

[0003] The purpose of this utility model is to provide a food processing machine with good noise reduction effect, so as to solve the problem that, even with the addition of a soundproof cover on the outside of the cup body and the setting of a recessed groove on the top of the main unit to reduce noise, the noise from the upper and lower connectors during operation directly impacts the inner wall of the soundproof cover and is transmitted outward, affecting the noise reduction effect of the soundproof cover.

[0004] To achieve the above objectives, this utility model provides a food processing machine with good noise reduction effect, including a main unit with a motor, a detachable grinding cup mounted on the main unit and having a grinding chamber inside, and a soundproof cover covering the outside of the grinding cup. The grinding chamber is equipped with a grinding device, which includes a grinding blade and an upper connector that is drivenly connected to the grinding blade. The top of the motor shaft is equipped with a lower connector that is drivenly connected to the upper connector. The top of the main unit is provided with a partially recessed groove, and the bottom wall of the groove is provided with an upwardly protruding positioning ring. The grinding cup includes a cup body and a cup base fixed below the cup body. The bottom end of the cup body is installed in the groove, and the bottom wall of the cup body is provided with a positioning groove to accommodate the positioning ring. The cup base is inserted between the positioning ring and the side wall of the groove. The soundproof cover is covered on the outside of the cup body, and its bottom end abuts against the top wall of the main unit.

[0005] This application features a recessed groove on the top of the main unit, into which the bottom of the cup is installed. This groove, by limiting the bottom of the cup after it is installed on the main unit, greatly improves the stability of the connection between the cup and the main unit. Additionally, the bottom wall of the groove has an upward-protruding positioning ring, and the bottom wall of the cup has a positioning groove to accommodate the positioning ring. The cooperation of the positioning ring and the positioning groove further enhances the positioning of the cup and the main unit, thereby improving the stability of their connection and preventing significant relative vibration and noise between the cup and the main unit during food processing, thus helping to reduce noise generation. Furthermore, the cup base is inserted between the positioning ring and the side wall of the sink, and the soundproof cover is placed on the outside of the cup body with its bottom end abutting against the top wall of the main unit. Through the positioning ring and positioning groove, the cup base and the side wall of the sink, and the soundproof cover, multiple layers of sound insulation structure are achieved for the upper and lower connectors. That is, multiple layers of sound insulation structure are formed on the outside of the upper and lower connectors, including the sound insulation of the positioning ring and positioning groove, the sound insulation of the cup base and the side wall of the sink, and the sound insulation of the soundproof cover. A meandering noise reduction path is formed between the various sound insulation structures. When the upper and lower connectors generate noise during transmission, the sound waves of the noise will encounter multiple refractions and reflections when propagating in the multi-layer sound insulation structure, resulting in energy loss. This effectively isolates the direct noise transmission between the upper and lower connectors and the soundproof cover, thereby effectively reducing the transmission of noise and greatly improving the overall noise reduction effect of the machine.

[0006] In a preferred embodiment of a food processing machine with good noise reduction effect, a handle is rotatably connected to the side wall of the cup body, and an annular sound insulation cavity is formed between the sound insulation cover and the side wall of the cup body, and the handle can be rotated and stored in the annular sound insulation cavity.

[0007] A handle is rotatably connected to the side wall of the cup body, and the handle can be rotated and stored in the annular sound insulation cavity. When the cup body needs to be lifted, the user can rotate the handle to a position that is easy to grip, so as to easily lift the entire cup body. When the cup body does not need to be lifted, the handle can be rotated and stored in the annular sound insulation cavity. This allows the annular sound insulation cavity to achieve sound insulation and noise reduction while also storing the handle, which saves space and maintains the overall aesthetics, and helps to reduce the radial space occupied by the whole machine.

[0008] In a preferred embodiment of a food processing machine with good noise reduction effect, the side wall facing the cup body is configured to conform to the side wall of the cup body, and when the handle is folded close to the cup body, the handle can be tightly attached to the side wall of the cup body.

[0009] By aligning the handle's sidewall facing the glass with the glass's sidewall, the handle can fit snugly against the glass when folded and stored, reducing its radial footprint and preventing interference with the soundproof cover. This also reduces the radial dimension of the soundproof cover, making the overall structure more compact. Furthermore, this design allows the soundproof cover to be a rotating body that matches the glass. Preferably, both the soundproof cover and the glass are cylindrical or nearly cylindrical. This allows users to install the soundproof cover at any angle; moreover, the circumferential distance between the soundproof cover and the glass is the same, ensuring that noise from the glass reaches the inner wall of the soundproof cover evenly. This radially cancels out the impact of noise on the soundproof cover and also causes reflected noise to cancel each other out, resulting in better noise reduction.

[0010] In a preferred embodiment of a food processor with good noise reduction effect, the crushing cup is further provided with a bottom cover fixed to the bottom of the cup body. The bottom cover has an upwardly recessed sound insulation groove in the middle. The upper connector is located in the sound insulation groove, and the lower connector is inserted into the sound insulation groove and connected to the upper connector in a transmission manner.

[0011] By providing an upwardly recessed sound insulation groove in the middle of the bottom cover, the upper connector is located in the sound insulation groove, and the lower connector is inserted into the sound insulation groove and connected to the upper connector in a transmission manner. This allows the noise generated when the upper and lower connectors are in motion to be effectively blocked in the sound insulation groove, further improving the overall noise reduction effect of the machine.

[0012] In a preferred embodiment of a food processor with good noise reduction effect, the grinding cup is further provided with a bottom cover fixed to the bottom of the cup body, and the outer wall of the bottom cover and the inner wall of the cup base form a positioning groove.

[0013] By setting the positioning groove to be formed by the outer wall of the bottom cover and the inner wall of the cup base, the positioning groove can be formed simultaneously with the bottom cover while it is connected and fitted to the cup base. This eliminates the need to form the positioning groove separately on the bottom cover, simplifies the production process, and helps to reduce production costs.

[0014] In a preferred embodiment of a food processing machine with good noise reduction effect, the bottom wall of the settling tank is provided with a shock-absorbing pad, and the bottom end of the cup base abuts against the top of the shock-absorbing pad.

[0015] By installing shock-absorbing pads on the bottom wall of the settling tank, and having the bottom of the cup base abut against the top of the shock-absorbing pads, on the one hand, flexible isolation between the cup base and the bottom wall of the settling tank can be achieved, effectively avoiding direct contact between the cup base and the bottom wall of the settling tank, which would cause collision noise during food processing, thus further reducing noise generation; on the other hand, by utilizing the sound absorption properties of the shock-absorbing pads, the noise generated during the transmission of the upper and lower connectors can be absorbed, thereby enhancing the overall noise reduction effect of the food processing machine.

[0016] In a preferred embodiment of a food processing machine with good noise reduction effect, the main unit is equipped with a micro switch, the positioning ring is provided with a clearance opening for the extension of the connecting rod of the micro switch, and the positioning groove is provided with a top rod that can be inserted into the clearance opening.

[0017] By incorporating a microswitch within the main unit, the microswitch is only triggered when the grinding cup is properly installed, ensuring the safe operation of the food processor. Simultaneously, the positioning ring features a clearance opening for the microswitch's connecting rod to extend from it, and a push rod that can be inserted into the clearance opening is located within the positioning groove. Compared to a design where the clearance opening is located inside the positioning ring, this reduces the radial space occupied by the clearance opening, thereby decreasing the overall radial dimension of the main unit and making the machine more compact, further enhancing its portability.

[0018] In a preferred embodiment of a food processing machine with good noise reduction effect, the positioning ring is further provided with a positioning notch, and the positioning groove is provided with a positioning protrusion that is inserted and matched with the positioning notch.

[0019] By providing a positioning notch in the positioning ring and a positioning protrusion in the positioning groove that engages with the positioning notch, the grinding cup, once installed on the main unit, can not only be effectively positioned through the cooperation of the positioning ring and the positioning groove, but also further limited by the engagement of the positioning notch and the positioning protrusion. This further enhances the stability of the connection between the grinding cup and the main unit, preventing vibration and noise caused by unstable connection.

[0020] In a preferred embodiment of a food processing machine with good noise reduction effect, the positioning ring, the sink, and the sound insulation cover are all coaxially arranged with the motor shaft.

[0021] By setting the positioning ring, sink, and soundproof cover coaxially with the motor shaft, the installation of the grinding cup is more convenient and quick. At the same time, the distance between the soundproof cover and the grinding cup can be nearly equal, so that noise can be better reflected and absorbed inside the soundproof cover, thereby further improving the noise reduction effect of the whole machine.

[0022] In a preferred embodiment of a food processing machine with good noise reduction effect, the outer periphery of the top wall of the main unit is provided with a stepped section with the stepped surface facing upward, and the bottom end of the soundproof cover abuts against the stepped surface.

[0023] By providing an upward-facing step on the outer periphery of the top wall of the main unit, and with the bottom of the soundproof cover abutting against the step surface, noise must bend downwards and outwards to escape to the outside when it travels through the soundproof cover, which helps to further improve the noise reduction effect.

Detailed Implementation

[0031] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0032] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1 to 4As shown, this utility model provides a food processing machine with good noise reduction effect, including a main unit 5 with a motor 4 inside, a detachable grinding cup 1 with a grinding chamber inside the main unit 5, and a soundproof cover 2 covering the outside of the grinding cup 1. The grinding chamber is provided with a grinding device 3, which includes a grinding blade 31 and an upper connector 32 that is drivenly connected to the grinding blade 31. The top of the motor 4 shaft of the motor 4 is provided with a lower connector 6 that is drivenly connected to the upper connector 32. The top of the main unit 5 is provided with a recessed groove 51, and the bottom wall of the groove 51 is provided with a positioning ring 511 that protrudes upward. The grinding cup 1 includes a cup body 11 and a cup base 12 fixed below the cup body 11. The bottom end of the cup body 11 is installed in the groove 51, and the bottom wall of the cup body 11 is provided with a positioning groove 14 to accommodate the positioning ring 511. The cup base 12 is inserted between the positioning ring 511 and the side wall of the groove 51. The soundproof cover 2 is covered on the outside of the cup body 11 and its bottom end abuts against the top wall of the main unit 5.

[0034] This application provides a recessed groove 51 at the top of the main unit 5, with the bottom of the cup body 11 installed within the groove 51. This design significantly improves the stability of the connection between the cup body 11 and the main unit 5 by limiting the bottom of the cup body 11 after it is installed on the main unit 5. Additionally, the bottom wall of the groove 51 has an upwardly protruding positioning ring 511, and the bottom wall of the cup body 11 has a positioning groove 14 to accommodate the positioning ring 511. The cooperation between the positioning ring 511 and the positioning groove 14 further enhances the positioning of the cup body 11 and the main unit 5, thereby improving the stability of their connection and preventing significant relative vibration and noise between the cup body 11 and the main unit 5 during food processing, thus helping to reduce noise generation. Furthermore, the cup base 12 is inserted between the positioning ring 511 and the side wall of the recess 51, and the sound insulation cover 2 is placed on the outside of the cup body 11 with its bottom end abutting against the top wall of the main unit 5. Through the positioning ring 511 and the positioning groove 14, the cup base 12 and the side wall of the recess 51, and the sound insulation cover 2, multiple layers of sound insulation structure are formed on the outside of the upper connector 32 and the lower connector 6, including the sound insulation of the positioning ring 511 and the positioning groove 14, the sound insulation of the cup base 12 and the side wall of the recess 51, and the sound insulation of the sound insulation cover 2. A meandering noise reduction path is formed between the various sound insulation structures. When the upper connector 32 and the lower connector 6 generate noise during transmission, the sound waves of the noise will encounter multiple refractions and reflections when propagating in the multi-layer sound insulation structure, resulting in energy loss. This effectively isolates the direct noise transmission between the upper connector 32 and the lower connector 6 and the sound insulation cover 2, thereby effectively reducing the transmission of noise and greatly improving the noise reduction effect of the whole machine.

[0035] As a preferred embodiment of this application, such as Figure 3 , Figure 4As shown, a handle 15 is rotatably connected to the side wall of the cup body 11, and an annular soundproof cavity is formed between the soundproof cover 2 and the side wall of the cup body 11. The handle 15 can be rotated and stored in the annular soundproof cavity.

[0036] By rotatably connecting a handle 15 to the side wall of the cup body 11, and by rotating the handle 15 into the annular sound insulation cavity, the user can easily lift the entire cup body 11 assembly by rotating the handle 15 to a position that is easy to grip when the cup body 11 assembly needs to be lifted; when the cup body 11 assembly does not need to be lifted, the handle 15 can be rotated into the annular sound insulation cavity, so that the annular sound insulation cavity can not only achieve sound insulation and noise reduction, but also store the handle 15, which saves space and maintains the overall aesthetics, and helps to reduce the radial space occupied by the whole machine.

[0037] Furthermore, such as Figure 4 As shown, the side wall of the handle 15 facing the cup body 11 is set in the same shape as the side wall of the cup body 11, and when the handle 15 is folded close to the cup body 11, the handle 15 can be in close contact with the side wall of the cup body 11.

[0038] By conforming the sidewall of the handle 15 facing the cup body 11 to the sidewall of the glass, the handle 15 can fit snugly against the cup body 11 when folded and stored, thus reducing the radial space occupied by the handle 15 when stored. This avoids interference with the soundproof cover 2 and also reduces the radial dimension of the soundproof cover 2, making the overall structure more compact. Furthermore, this design allows the soundproof cover 2 to be a rotating body that matches the cup body 11. Preferably, both the soundproof cover 2 and the cup body 11 are cylindrical or approximately cylindrical. This allows users to install the soundproof cover 2 at any angle. Additionally, the circumferential distance between the soundproof cover 2 and the cup body 11 is the same, ensuring that noise emitted from the cup body 11 reaches the inner wall of the soundproof cover 2 evenly. This radially cancels the impact of noise on the soundproof cover 2 and also causes reflected noise to cancel each other out, resulting in better noise reduction.

[0039] As a preferred embodiment of this application, such as Figure 2 As shown, the crushing cup 1 is also provided with a bottom cover 13 fixed to the bottom end of the cup body 11. The bottom cover 13 has an upwardly recessed sound insulation groove 131 in the middle. The upper connector 32 is located in the sound insulation groove 131, and the lower connector 6 is inserted into the sound insulation groove 131 and is connected to the upper connector 32 in a transmission manner.

[0040] By providing an upwardly recessed sound insulation groove 131 in the middle of the bottom cover 13, with the upper connector 32 located inside the sound insulation groove 131 and the lower connector 6 inserted into the sound insulation groove 131 and connected to the upper connector 32, the noise generated when the upper connector 32 and the lower connector 6 are in motion can be effectively blocked in the sound insulation groove 131, further improving the noise reduction effect of the whole machine.

[0041] It should be noted that this application does not specifically limit the forming method of the positioning groove 14. As one preferred embodiment of this application, such as... Figure 2 As shown, the crushing cup 1 is also provided with a bottom cover 13 fixed to the bottom end of the cup body 11. The outer side wall of the bottom cover 13 and the inner side wall of the cup base 12 form a positioning groove 14.

[0042] By setting the positioning groove 14 to be formed by the outer wall of the bottom cover 13 and the inner wall of the cup base 12, the bottom cover 13 can achieve connection and cooperation with the cup base 12 while the positioning groove 14 can be formed simultaneously. This eliminates the step of separately forming the positioning groove 14 on the bottom cover 13, simplifies the production process, and helps to reduce production costs.

[0043] As a preferred embodiment of this application, such as Figure 2 As shown, the bottom wall of the settling tank 51 is provided with a shock-absorbing pad 7, and the bottom end of the cup base 12 abuts against the shock-absorbing pad 7.

[0044] By providing a shock-absorbing pad 7 on the bottom wall of the settling tank 51, and having the bottom end of the cup base 12 abut against the top of the shock-absorbing pad 7, on the one hand, flexible isolation between the cup base 12 and the bottom wall of the settling tank 51 can be achieved, effectively preventing direct contact between the cup base 12 and the bottom wall of the settling tank 51, which would cause collision noise during food processing, and further reducing noise generation; on the other hand, by utilizing the sound absorption performance of the shock-absorbing pad 7, the noise generated during the transmission of the upper connector 32 and the lower connector 6 can be absorbed, thereby enhancing the overall noise reduction effect of the food processing machine.

[0045] As a preferred embodiment of this application, such as Figure 3 As shown, the main unit 5 is equipped with a micro switch 8, and the positioning ring 511 is equipped with a clearance opening 5111 for the extension of the connecting rod of the micro switch 8. The positioning groove 14 is equipped with a top rod that can be inserted into the clearance opening 5111.

[0046] By incorporating a microswitch 8 within the main unit 5, the microswitch 8 is only triggered when the grinding cup 1 is properly installed, thus ensuring the safe operation of the food processor. Simultaneously, the positioning ring 511 has a clearance opening 5111 for the extension of the connecting rod of the microswitch 8, and the positioning groove 14 has a push rod that can be inserted into the clearance opening 5111. Compared to a design where the clearance opening 5111 is located inside the positioning ring 511, this reduces the radial space occupied by the clearance opening 5111, thereby reducing the overall radial dimension of the main unit 5, making the entire machine more compact, and further improving the product's portability.

[0047] As a preferred embodiment of this application, such as Figure 3As shown, the positioning ring 511 is also provided with a positioning notch 5112, and the positioning groove 14 is provided with a positioning protrusion that is inserted and engaged with the positioning notch 5112.

[0048] By providing a positioning notch 5112 in the positioning ring 511 and a positioning protrusion in the positioning groove 14 that engages with the positioning notch 5112, the crushing cup 1, after being installed on the host 5, can not only be effectively positioned by the cooperation of the positioning ring 511 and the positioning groove 14, but also further limited by the engagement of the positioning notch 5112 and the positioning protrusion. This further improves the stability of the connection between the crushing cup 1 and the host 5, and avoids vibration and noise caused by unstable connection between the two.

[0049] Of course, the positioning notch 5112 and the positioning protrusion are not limited to the above-mentioned settings. Alternatively, the positioning notch 5112 can be set in the positioning groove 14 and the positioning protrusion can be set on the positioning ring 511. This will not be elaborated further here.

[0050] As a preferred embodiment of this application, such as Figure 1 As shown, the positioning ring 511, the sink 51, and the soundproof cover 2 are all coaxially arranged with the motor 4 shaft of the motor 4.

[0051] By setting the positioning ring 511, the sink 51, and the soundproof cover 2 coaxially with the motor 4 shaft of the motor 4, the installation of the crushing cup 1 is more convenient and quick. At the same time, the distance between the soundproof cover 2 and the crushing cup 1 can be nearly equal, so that noise can be better reflected and absorbed inside the soundproof cover 2, thereby further improving the noise reduction effect of the whole machine.

[0052] As a preferred embodiment of this application, such as Figure 2 As shown, the outer periphery of the top wall of the main unit 5 is provided with a stepped section with the stepped surface 52 facing upwards, and the bottom end of the soundproof cover 2 abuts against the stepped surface 52.

[0053] By providing an upward-facing stepped section with a stepped surface 52 on the outer periphery of the top wall of the main unit 5, and having the bottom end of the soundproof cover 2 abutting against the stepped surface 52, noise needs to be discharged to the outside through a downward and outward bending path when it propagates to the outside through the soundproof cover 2, which helps to further improve the noise reduction effect.

[0054] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
