[0045] As Figure 1-8 shown, this embodiment discloses a food processing and treatment device with a noise reduction mechanism.

[0046] A food processing and treatment device with a noise reduction mechanism includes

[0047] a base 100, which is configured with a driving component 120 inside a housing 110, and the output end of the driving component 120 extends above the base 100;

[0048] a cooking cup 200, which is arranged above the base 100, and the output end of the driving component 120 can extend into the cooking cup 200;

[0049] a cooking head 600, which is located inside the cooking cup 200 and is connected to the output end of the driving component 120, and is driven by the driving component 120 to process the food inside the cooking cup 200;

[0050] including a noise reduction device for reducing the noise of the cooking cup 200 and / or the base 100;

[0051] the noise reduction device includes a first noise reduction box 300, and at least a first noise reduction cavity is arranged inside the housing of the first noise reduction box 300; an air inlet 301 and an air outlet 302 are arranged on the housing and are communicated with the first noise reduction cavity;

[0052] an air flow driving component 130 drives the air inside the cooking cup 200 and / or the base 100 to form an air flow, and the air flow is output after passing through the first noise reduction box 300;

[0053] the cross-sectional areas of the air inlet 301 and the air outlet 302 are both smaller than the cross-sectional area of the noise reduction cavity.

[0054] The above is the basic solution of this embodiment.

[0055] Specifically referring to Figure 1 - Figure 2 shown, the cooking head 600 is a cutting knife and is connected to the output shaft of the driving component 120, and the driving component 120 drives the cutting knife to rotate to cut the food inside the cooking cup 200;

[0056] The usage mode of this embodiment is the same as that of a food processor that processes food with a cutting knife in the prior art, and will not be elaborated here.

[0057] In the setting of the food processor of this embodiment, the noise usually comes from the noise generated by the driving component 120 itself during operation, the sound generated when the cooking head 600 cuts food, and the sound generated when the food impacts the inner wall of the cooking cup 200. Therefore, during the noise reduction process, it is necessary to reduce the noise not only for the base 100 but also for the cooking cup 200 part.

[0058] In this embodiment, a noise reduction device is provided to reduce the noise of the base 100 and / or the cooking cup 200 to meet the noise elimination requirement.

[0059] In this embodiment, the noise reduction principle of the noise reduction device is as follows: Noise is conducted through air as a carrier. Therefore, it is only necessary to reduce the noise of the air. A first noise reduction box 300 is provided, and a first noise reduction cavity is reasonably arranged in the first noise reduction box 300. The cross-sectional areas of the air inlet 301 and the air outlet 302 are both smaller than the cross-sectional area of the first noise reduction cavity. That is to say, when the air flow enters the first noise reduction cavity through the air inlet 301, the cross-sectional area increases, and the air flow suddenly diffuses, resulting in a gradual attenuation of the sound energy per unit cross-sectional area of the air flow. When it is output to the outside through the air outlet 302, the cross-sectional area per unit decreases, and the sound energy passing through also decreases. Thus, the air flow is noise-reduced again, thereby completing the noise elimination of the base 100.

[0060] In this embodiment, the driving component 120 is preferably a driving motor, and is provided with two output shafts. One output shaft is connected upward to the cooking head 600, and the other output shaft is connected downward to an air flow driving component 130.

[0061] Preferably, in this embodiment, the air flow driving component 130 is a fan.

[0062] When the first noise reduction box 300 is arranged on the cooking cup 200, an air port is arranged on the top cover of the cooking cup 200 and is communicated with the air inlet 301 of the first noise reduction box 300.

[0063] When the first noise reduction box 300 is arranged on the base 100, the chamber for accommodating the driving component 120 is communicated with the air inlet 301, and an air outlet grille 110.1 is arranged at the bottom of the base 100 and is communicated with the air outlet 302.

[0064] In this embodiment, a diversion channel a and a noise reduction groove b are arranged in the first noise reduction cavity through a first partition structure, and the diversion channel a and the noise reduction groove b communicate the air inlet 301 and the air outlet 302.

[0065] To increase the noise reduction effect, in this embodiment, a special diversion channel a is provided in the first noise reduction chamber to enable the air flow to have a longer movement path in the first noise reduction chamber and improve the noise reduction effect. Specifically, refer to Figure 3 As shown, the diversion channel a is connected to the air inlet 301, guiding the air flow to the noise reduction groove b. After the air flow diffuses and undergoes multiple reflections and refractions in the noise reduction groove b, the noise energy in the air flow is attenuated, and then the noise-reduced air flow is output from the air outlet 302.

[0066] In particular, in this embodiment, the diversion channel a is provided, and the cross-sectional area of the diversion channel a is smaller than the area of the air inlet 301. Therefore, the air flow undergoes a noise reduction effect when entering the diversion channel a.

[0067] Among them, the air inlet 301 is located in the middle of the housing, and the diversion channel a is arranged radially outward from the air inlet 301;

[0068] The first partition structure includes a first partition 310 in a cross shape. The first partition 310 is radially arranged around the air inlet 301 and forms a noise reduction groove b with an opening between the first partition 310 and the flange of the air inlet 301.

[0069] The air flow enters the first noise reduction chamber from the air inlet 301 in the middle of the first noise reduction box 300. After entering the diversion channel a, it moves radially outward along the diversion channel a. During the movement, part of the air flow is introduced into the noise reduction groove b, collides with the inner wall of the first partition 310 in the noise reduction groove b, and then is output from the opening after reflection or refraction, and continues to move along the diversion channel a until it reaches the air outlet 302.

[0070] Specifically, in this embodiment, the first partition 310 includes an intersecting first rib 311 and a second rib 312. The first rib 311 extends radially from the air inlet 301, and both ends of the second rib 312 are provided with side blocking segments 313 that are bent toward the air inlet 301.

[0071] Specifically, refer to Figure 3 As shown, in this embodiment, the first rib 311 extends radially from the edge of the air inlet 301, and the second rib 312 is perpendicular or angled to the first rib 311. Two noise reduction grooves b are separated on both sides of the first rib 311, and side blocking segments 313 are provided at both ends of the second rib 312 to set the opening direction of the noise reduction groove b, so that the direction of the air flow entering the noise reduction groove b is inclined relative to the diversion channel a.

[0072] Preferably, in this embodiment, two second rib positions 312 are provided on the first rib position 311. Therefore, the two second rib positions 312 also partition out noise reduction grooves b, increasing the number of noise reduction grooves b, so that as much air flow in the diversion channel a as possible can enter the noise reduction grooves b for noise reduction.

[0073] Preferably, in this embodiment, the first partition structure further includes a second partition 320. The second partition 320 extends radially from the air inlet 301 and is located between two adjacent first partitions 310.

[0074] Specifically referring to Figure 4 As shown, by providing the second partition 320, the diversion channel a is divided into two small channels, and the air flows in the two small channels can respectively enter the noise reduction grooves b on both sides, further improving the noise reduction effect.

[0075] In this embodiment, to increase the moving path of the air flow, a second noise reduction cavity is further provided in the housing. The first noise reduction cavity and the second noise reduction cavity are separated up and down by a partition layer 330. A second partition structure opposite to the direction of the first partition structure is provided in the second noise reduction cavity;

[0076] The first noise reduction cavity and the second noise reduction cavity are communicated through an air passing hole 331.

[0077] Specifically referring to Figure 5 As shown, the first noise reduction box 300 is successively provided with a top seat 340, a partition layer 330, and a bottom seat 350 from top to bottom. The first noise reduction cavity is located between the top seat 340 and the partition layer 330, and the second noise reduction cavity is located between the partition layer 330 and the bottom seat 350; the air passing hole 331 is provided on the partition layer 330;

[0078] Moreover, in order to extend the moving path, the air passing hole 331 is provided at a position close to the outer wall of the first noise reduction box 300, and the air outlet 302 is provided at the central part of the bottom case.

[0079] When the air flow moves, it enters the first noise reduction cavity through the air inlet 301 and moves radially outward in the first noise reduction cavity. During the movement, it is noise-reduced through the noise reduction groove b; when it moves to the outer ring of the first noise reduction cavity, it enters the second noise reduction cavity through the air passing hole 331 and also moves radially inward in the second noise reduction cavity. During the movement, it is noise-reduced through the noise reduction groove b, and then reaches the central air outlet 302 for output.

[0080] In this embodiment, the second partition structure and the first partition structure are only set as reverse structures in terms of direction, and other structures are the same, so no further description will be given here;

[0081] At the same time, in this embodiment, the second partition 320 is provided on the end face of the partition layer 330.

[0082] In this embodiment, a sound insulation cotton is further included.

[0083] In this embodiment, the air outlet 302 is arranged in the middle of the base 350, and the sound insulation cotton is filled at the position of the air outlet 302. When the air flow outputs from the air outlet 302, it passes through the sound absorption effect of the sound insulation cotton for another noise reduction.

[0084] Preferably, in this embodiment, the first noise reduction box 300 is arranged in the base 100 to reduce the noise generated by the driving component 120. At the same time, a sound insulation shell 700 is arranged outside the driving component 120, and a sound absorption hole is arranged at the bottom of the sound insulation shell 700. The noise generated by the driving component 120 is isolated in the sound insulation shell 700, and under the action of the air flow driving component 130, it forms an air flow with the air in the sound insulation shell 700 and enters the first noise reduction box 300 through the sound absorption hole.

[0085] Preferably, in order to support the sound insulation shell 700, support ribs 710 are arranged on the lower end surface of the sound insulation shell 700, and the support ribs 710 abut against the first noise reduction box 300 to support the sound insulation shell 700.

[0086] In this embodiment, a coupler 800 is arranged on the base 350, and the coupler 800 electrically connects the driving component 120 and the circuit system in the base 100; the driving component 120 can be taken out from the base 100 together with the cooking cup 200; during installation, the driving component 120 is placed on the base 100 and the coupler 800 is connected to achieve power on.

[0087] Preferably, in this embodiment, the lower part of the coupler 800 is arranged on the first noise reduction box 300.

[0088] In other embodiments, if the first noise reduction box 300 is arranged on the cooking cup 200, the sound absorption member 710 can be arranged between the air outlet part of the cooking cup 200 and the first noise reduction box 300.

[0089] In this embodiment, the first noise reduction box 300 is arranged in the base 100. In order to reduce the noise in the cooking cup 200, the noise reduction device further includes a second noise reduction box 500;

[0090] The first noise reduction box 300 is arranged in the base 100, and the second noise reduction box 500 is arranged on the cooking cup 200;

[0091] The second noise reduction box 500 is provided with an air inlet hole 502 and an air outlet hole 501, and the cross-sectional area of the air flow passing through the air inlet hole 502 and the air outlet hole 501 is smaller than the cross-sectional area of the third noise reduction cavity in the second noise reduction box 500.

[0092] In this embodiment, the noise reduction principle of the second noise reduction box 500 is the same as that of the first noise reduction box 300, and will not be elaborated here.

[0093] Wherein, a sound insulation cover 400 is arranged outside the cooking cup 200; the second noise reduction box 500 is arranged on the sound insulation cover 400, and the second noise reduction box 500 is arranged on the sound insulation cover 400 and extends into the cooking cup 200.

[0094] The lower end of the sound insulation cover 400 is open, detachably connected to the base 100, and completely covers the cooking cup 200, forming a sound insulation space in the inner cavity;

[0095] The second noise reduction box 500 is arranged on the top of the sound insulation cover 400 and extends into the cooking cup 200 to communicate with the inner cavity of the cooking cup 200.

[0096] Specifically, in this embodiment, an air inlet protrusion 510 is provided on the lower end surface of the second noise reduction box 500, an air inlet channel is arranged on the air inlet protrusion 510, and the air inlet hole 502 is arranged on the side of the air inlet protrusion 510 to connect the air inlet channel.

[0098] The wind guide sleeve 211 is connected to the wind guide neck 520 to form a wind guide space in the wind guide neck 520. The air flow in the cooking cup 200 enters the wind guide space through the wind groove on the cup cover 210, and then moves along the air inlet channel through the air inlet hole 502 into the second noise reduction box 500 and is output to the outside from the air outlet hole 501 of the second noise reduction box 500;

[0099] When the air flow enters the air inlet channel from the wind guide space, the cross-sectional area of the flow-through section decreases, and the entering air flow is noise-reduced for the first time. When the air flow enters the second noise reduction cavity from the air inlet channel, the cross-sectional area of the flow-through section increases, so the second noise reduction is carried out; when the air flow is output to the outside from the air outlet hole 501, the cross-sectional area of the flow-through section decreases again, so the noise reduction is carried out once again.
