The present application provides a food processor. The food processor includes: host computer body 6 be provided with motor 7 in the host computer body 6, the assembly is in cup 3 on the host computer body 6 install cutter unit spare 4 on the cup 3, wherein, cutter unit spare 4 includes: a central rotating shaft 2; a blade 41 mounted on the central spindle 2 and inside the cup 3; and the transmission gear 1 is fixedly connected with the central rotating shaft 2, and the transmission gear 1 is driven by the motor 7. The motor 7 drives the cutter component 4 to rotate through the transmission seat 8 and the transmission teeth 1 so as to stir or smash the articles in the cup body 3.

As shown in fig. 2 and 3, the transmission gear 1 includes an inner core body 11 and an encapsulating layer 12 covering the inner core body 11. The inner core body 11 is configured with a plurality of teeth 111 extending radially outward, the teeth 111 including a drive zone 1111 for driving and a reduced-size guide zone 1112 at the end of the drive zone 1111. The encapsulating layer 12 is wrapped on the transmission zone 1111, and the guide zone 1112 is exposed relative to the encapsulating layer 12. According to this structure, as shown in fig. 2, in the assembled state, the transmission zone 1111 is engaged with the transmission seat 8, and the guide zone 1112 is spaced apart from the transmission seat 8. Therefore, the food processor can reduce the transmission noise between the transmission seat 8 and the transmission teeth 1 through the encapsulating layer 12 in the stirring process by coating the encapsulating layer 12 at the position of the transmission area 1111 of the transmission teeth 1. The guide region 1112 is not coated with the encapsulating layer, so that even if the assembly of the cutter assembly 4 is slightly deviated, the guide region 1112 is in sharp contact with the transmission seat 8, the encapsulating layer 12 cannot be damaged, the service life of the cutter assembly 4 is prolonged, and in the case of normally assembling the cutter assembly 4, the guide region 1112 is not in contact with the transmission seat 8, so that additional transmission noise cannot be generated.

In one embodiment, the ratio of the length of the drive zone 1111 to the guide zone 1112 is (3:1) - (5: 1). With this structure, the guide region 1112 is small in size, so that even if the guide region 1112 is not in contact with the holder 8, the torque transmission effect is not affected and no additional transmission noise is generated in the case of normal assembly of the tool assembly. In one particular embodiment, the ratio of the length of the drive zone 1111 to the guide zone 1112 is 3.6: 1. More specifically, the drive zone 1111 is 9.7mm in length and the guide zone 1112 is 2.7mm in length.

In further embodiments, the guide region 1112 tapers in width and/or thickness along the drive region 1111 to the guide region 1112. Specifically, the guiding region 1112 may be in the shape of a pyramid, a cone, a truncated pyramid, a truncated cone, or the like. This shape of the guide region 1112 serves to guide the mounting when the gear 1 is assembled with the gear seat 8, facilitating the drive mounting between the gear 1 and the gear seat 8. It should be understood that the width described herein is the circumferential dimension of the guide region 1112 and the thickness is the radial dimension of the guide region 1112.

The inner core body 11 is made of hard material, and the rubber coating layer 12 is made of elastic material. For example, the hard material may be a metal material or a hard plastic, and the elastic material may be rubber or PVC or silicone. The inner core body 11 supported by the hard material ensures the transmission stability of the transmission seat 8 and the transmission teeth 1, so that the beating effect of the blade 41 is ensured; the encapsulating layer 12 is used for effectively reducing transmission noise generated in the rotating process.

Fig. 4 schematically shows the cutter assembly 4. As shown in fig. 5 and 6, the motor 7 includes an output shaft 71, and a transmission base 8 is provided on the output shaft 71. The cutter member 4 includes: a central rotating shaft 2; a blade 41 mounted on the central spindle 2 and inside the cup 3; and a driving gear 1 installed on the central rotating shaft 2 and offset from the blade 41, the driving gear 1 being drivingly engaged with the driving seat 8.

To stably mount the cutter assembly 4 to the cup body 3, the food processor further includes a cutter mounting ring 42 (shown in fig. 5). Tool mounting ring 42 is removably engaged with tool assembly 4 and pressed against cup body 3 to fixedly mount tool assembly 4 to cup body 3. In a specific embodiment, the cutter assembly 4 includes a bearing 43 and a bearing sleeve 44, and the bearing sleeve 44 is fixedly sleeved outside the bearing 43. A bearing 43 and a bearing bush 44 are mounted on the bottom wall 31 of the cup body 3, and the bearing 43 carries the central rotating shaft 2. The bearing sleeve 44 is provided with threads, the cutter mounting ring 42 is of an annular structure, and the inner wall of the cutter mounting ring 42 is provided with threads matched with the bearing sleeve 44. Thus, as the tool mounting ring 42 is threaded with the bearing sleeve 44, the tool mounting ring 42 is also tightly and fixedly press-fitted against the bottom wall 31 of the cup body 3, thereby fixedly mounting the tool assembly 4 on the cup body 3. It should be understood that the removable engagement of the tool mounting ring 42 and the tool assembly 4 (or the bearing sleeve 44) may also be a form fit manner such as a plug-in structure fit or an interference fit, and will not be described herein again.

In order to ensure a secure mounting of the tool mounting ring 42 between the cup bodies 3, an elastic body 5 is provided compressed between the tool mounting ring 42 and the bottom wall 31 of the cup body 3. Thus, as the cutter mounting ring 42 is tightened onto the bearing sleeve 44, the elastomer 5 is compressed between the bottom wall 31 of the cup 3 and the cutter mounting ring 42. Elastomer 5 greatly increases the resistance to movement of tool mounting ring 42 relative to bottom wall 31 of cup 3, which ensures that tool mounting ring 42 is always fixedly mounted to bottom wall 31 of cup 3, and thus tool assembly 4 remains fixedly mounted to cup 3.

As shown in fig. 5, a first groove 421 is formed in the surface of the cutter mounting ring 42 facing the bottom wall 31 of the cup body 3, and a first boss 311 is formed in the bottom wall 31 of the cup body 3. The elastic body 5 is disposed in the first groove 421 and compressed by the first boss 311. In this structure, the first groove 421 acts as a limit for the elastic body 5, so that the elastic body 5 is conveniently and fixedly mounted; in addition, the first boss 311 compresses the elastic body 5, so that the friction force between the cutter mounting ring 42 and the bottom wall 31 of the cup body 3 is effectively increased, and the cutter assembly 4 is not easy to loosen after being mounted.

In one embodiment, the first recess 421 is an annular groove, the elastic body 5 is an annular ring, and the first boss 311 is an annular boss. Thus, after the tool mounting ring 42 is mounted on the bottom wall 31 of the cup body 3, the pressing force applied to the elastomer 5 is uniform, which further helps to ensure that the tool assembly 4 is not easily loosened after mounting.

In other embodiments, the first recess 421 may be an annular groove, the resilient body 5 may be an annular ring, and the first boss 311 may be a plurality of discrete bosses. In addition, the first recess 421 may also be a plurality of discrete grooves, the elastic body 5 includes a plurality of discrete elastic blocks, each groove is correspondingly provided with an elastic block, or the elastic body 5 includes a plurality of connected elastic blocks, and the thickness of the connecting part between the elastic blocks is smaller than that of the elastic blocks so as to facilitate the installation of the elastic blocks into the plurality of discrete grooves. The first land 311 may be an annular land or a plurality of discrete lands, the locations of which match the locations of the discrete grooves.

As also shown in fig. 5, a second boss 312 is also formed on the bottom wall 31 of the cup body 3. When first boss 311 compresses tightly in elastomer 5, second boss 312 and cutter mounting ring 42 contact to realize the stable contact of diapire 31 and cutter mounting ring 42 of cup 3, avoid producing relative rocking between cup 3 and the cutter mounting ring 42, thereby guarantee that cutter unit 4 installs stably.

Both the second boss 312 and the first boss 311 are configured on the bottom wall 31 of the cup body 3, and the second boss 312 is located inside the first boss 311 and forms a concentric ring. By configuring the second boss 312 and the first boss 311 to form a concentric ring, consistency of contact effect of the second boss 312 and the cutter mounting ring 42 in different radial directions is ensured, and stability of the cutter assembly 4 is further improved.

In addition, the height of the second bosses 312 is greater than or equal to the height of the first bosses 311. In this case, the elastic body 5 protrudes out of the first groove 421 before being pressed by the first boss 311. In one embodiment, the difference between the height of the second boss 312 and the height of the first boss 311 is 0 to 0.4mm, preferably 0.3 mm. With this structure, it is ensured that the second boss 312 will abut against the tool mounting ring 42 while the first boss 311 presses the elastic body 5, which further ensures that the tool assembly 4 will be stably mounted on the cup body 3 and avoids relative shaking between the cup body 3 and the tool mounting ring 42.

It should be understood that the first boss 311 and the second boss 312 may also be provided on the cutter mounting ring 42, and the first recess 421 is provided on the bottom wall 31 of the cup body 3, which will not be described herein.

Further, a surface of the cutter attachment ring 42 remote from the bottom wall 31 of the cup body 3 is provided with a mounting and dismounting operation groove 422. The mounting and dismounting operation groove 422 is used for placing mounting tools, which facilitates mounting and dismounting of the cutter mounting ring 42.

In addition, as shown in fig. 7 and 8, the food processor of the present application further includes a main body 6, and the main body 6 includes a body 61 and a body upper cover 62 detachably mounted above the body 61. The motor 7 is arranged in a space enclosed by the body 61 and the upper cover 62, and the motor 7 is suspended on the body upper cover 62. In addition, the upper body cover 62 is fixedly connected to the body 61 through a mounting portion 622, the mounting portion 622 is configured on the upper body cover 62 or the body 61, and a second shock pad 623 is disposed on the mounting portion 622.

In the food processor of the present application, the motor 7 is hung on the body upper cover 62. Compared with the case that the motor 7 is arranged on the machine body 61 or the machine body lower cover 63, the assembling error accumulation of the motor 7 and the cutter assembly 4 is greatly reduced, so that the higher coaxiality between the motor 7 and the cutter assembly 4 is ensured, and the vibration noise generated when the motor 7 rotates at a high speed is reduced. In addition, the second shock absorbing pad 623 stably holds the fixing member 624 (e.g., a screw) passing through it to connect the body cover 62 and the body 61, which greatly reduces the possibility of relative displacement between the body cover 62 and the body 61, thereby further ensuring high coaxiality between the motor 7 and the cutter assembly 4, and further contributing to reducing the vibration noise generated when the motor 7 rotates at high speed. In addition, the second shock absorbing pad 623 itself also has a good buffering function, which also helps to reduce the generation of vibration noise by the body cover 62.

In one embodiment, the second shock pad 623 is made of an elastic material such as rubber or PVC or silicone.

As shown in fig. 9, 10, 11, 12 and 13, the motor bracket 9 is provided with a second mounting hole 95 and a semi-closed first mounting hole 91, a second mounting screw 94 passes through the mounting hole 72 on the motor 7 and is fixed on the second mounting hole 95, a first shock pad 92 is arranged in the first mounting hole 91, and a first mounting screw 93 passes through the motor cover 10 and the first shock pad 92 outside the motor 7 and is fixedly connected with the machine body upper cover 62 so as to suspend and mount the motor 7 on the machine body upper cover 62 through the motor bracket 9. According to this structure, the semi-closed first mounting hole 91 facilitates the installation of the first cushion 92 therein even if the outer diameter of the first cushion 92 is larger than the inner diameter of the first mounting hole 91 (for example, a portion of the first cushion 92 may be extruded out of the notch of the first mounting hole 91). The first shock-absorbing pad 92 tightly installed in the first installation hole 91 can play a role of buffering the shock generated during the high-speed rotation of the motor 7, prevent the displacement of the motor 7 relative to the machine body upper cover 62, ensure the coaxiality of the motor 7 and the cutter assembly 4, and thus reduce the shock noise.

In one embodiment, the first cushion 92 is made of an elastic material such as rubber or PVC or silicone.

In further embodiments, the first cushion 92 is an annular structure having an outer diameter greater than or equal to an inner diameter of the first mounting hole 91. Thus, after the first cushion 92 is installed in the first installation hole 91, the first cushion 92 is closely attached to the inner wall of the first installation hole 91.

In another embodiment, a sound insulation cover can be arranged outside the cup body 3. The sound-proof housing can be dismantled and fix on cup 3, and this helps reducing the outgoing of food processor during operation noise, plays better syllable-dividing effect.
