Description

Technical Field

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

[0002] The existing food processing machine usually includes a cup body with a crushing chamber, a cup cover covering the cup body, a motor arranged at the bottom of the cup body, and a housing for accommodating the motor. The rotating shaft driven by the motor penetrates the bottom wall of the cup body and extends into the cup body. A crushing device is arranged at the end of the rotating shaft. When the user uses the food processing machine, the food is placed in the crushing chamber, and the crushing device rotates at high speed under the drive of the motor to realize the processing of the food. In the process of assembling the motor, in order to achieve the fixation of the motor, a motor bracket is usually arranged above the motor, and the motor is fixed under the cup body through the motor bracket. When the motor bracket and the motor are fixedly connected, the two are fixedly connected by a fixing member. However, the motor will generate a large vibration when rotating at a high speed. After the vibration is transmitted to the motor bracket, it will be transmitted to the cup body and other components through the motor bracket, causing a large vibration noise of the whole machine. In order to reduce the transmission of noise, some manufacturers will set a shock-absorbing member between the motor bracket and the fixing member to isolate the two, and reduce the transmission of vibration from the motor to the motor bracket through the buffering and shock-absorbing effect of the shock-absorbing member. However, during the actual assembly of the motor, the assemblers will screw the fixings and the motor bracket too tightly, causing the shock absorber clamped between the fixings and the motor bracket to be compressed too much, which in turn causes the shock absorber to lose its elasticity and buffering and shock-absorbing function, resulting in a deterioration in the shock-absorbing effect of the entire machine. Larger vibration noise will be generated during the food processing process, seriously affecting the consumer experience. Utility Model Content

[0003] The utility model aims to provide a food processing machine with good shock-absorbing effect, so as to solve the problem that in the existing food processing machine, the fixing piece for fixing the motor bracket to the motor is screwed too tightly with the motor bracket, causing the shock-absorbing piece clamped between the motor bracket and the fixing piece to be compressed too much, thereby causing the shock-absorbing piece to lose elasticity and buffer shock absorption.

[0004] To achieve the above-mentioned purpose, the utility model provides a food processing machine with good shock-absorbing effect, comprising a cup body with a crushing chamber, a motor arranged at the bottom of the cup body, a rotating shaft driven by the motor penetrating the bottom wall of the cup body and extending into the cup body, a crushing device is arranged at the end of the rotating shaft, the food processing machine also comprises a motor bracket and a fixing member fixing the motor bracket to the motor, a shock-absorbing member is arranged between the fixing member and the motor bracket to isolate the two, the fixing member comprises a threaded portion arranged at the front end, a limiting portion arranged at the rear end and a connecting portion connecting the two, the threaded portion is fastened to the motor, the limiting portion is located at the outside of the motor bracket, the motor bracket is provided with an avoidance hole, the shock-absorbing member comprises a shock-absorbing ring isolated between the limiting portion and the motor bracket and a shock-absorbing sleeve isolated between the connecting portion and the avoidance hole, a protrusion protruding outward relative to the threaded portion is arranged on the connecting portion, and when the fixing member is installed in place, the protrusion abuts against the outer wall of the motor.

[0005] The present application provides a shock-absorbing member between the fixing member and the motor bracket to isolate the two, so that after the motor bracket is fixedly connected to the motor through the fixing member, the fixing member and the motor bracket are flexibly isolated through the shock-absorbing member, so that when the food processing machine is working, the vibration generated by the high-speed rotation of the motor is transmitted to the motor bracket through the fixing member, and the vibration is reduced by the shock-absorbing member, effectively reducing the transmission of the vibration to the motor bracket, and then reducing the transmission of the vibration on the motor bracket to the cup body, achieving the effect of shock reduction and noise reduction. At the same time, the shock-absorbing member includes a shock-absorbing ring isolated between the limiting part and the motor bracket and a shock-absorbing sleeve isolated between the connecting part and the avoidance hole, which realizes the all-round isolation of the motor bracket and the fixing member, further reducing the transmission of vibration to the motor bracket, and at the same time, the shock-absorbing sleeve can limit the central positioning of the fixing member, thereby ensuring the coaxiality of the fixing member and the avoidance hole, thereby ensuring the coaxiality of the motor and the motor bracket, and improving the stability of operation.

[0006] In addition, the connecting portion is provided with a protrusion protruding outward relative to the threaded portion. When the fixing part is installed in place, the protrusion abuts against the outer wall of the motor. Compared with the existing method in which the lower part of the fixing part is entirely a threaded portion, the protrusion can abut against the outer wall of the motor when the fixing part is installed in place, thereby realizing axial positioning of the fixing part. On the one hand, it can enable the assembler to feel that the fixing part has been installed in place and does not need to be further tightened; on the other hand, under the limiting effect of the outer wall of the motor, the fixing part cannot be further tightened, so that the fixing part can be fixed in a reasonable limiting space during assembly, avoiding the fixing part being screwed too tightly during assembly, resulting in excessive squeezing of the flexible part, especially the shock-absorbing ring, by the fixing part, resulting in the shock-absorbing ring being unable to provide buffering and shock-absorbing, which in turn causes the motor to transmit greater vibration to the motor bracket, thereby ensuring the shock-absorbing effect of the shock-absorbing part and reducing the generation of vibration noise.

[0007] In a preferred implementation of a food processor with good shock absorption effect, the outer diameter of the connecting portion is enlarged relative to the threaded portion to form a step surface toward one side of the connecting portion, and the step surface forms a protrusion that abuts against the outer wall of the motor.

[0008] By setting the step surface to expand the outer diameter of the connecting part relative to the threaded part to form a step surface facing one side of the connecting part, when the fixing part is installed in place, the step surface abuts against the outer wall of the motor, thereby achieving axial positioning of the fixing part and preventing the fixing part from being further tightened. At the same time, the expansion of the outer diameter of the connecting part can realize the molding of the bulge, which has a simple structure and is convenient for demolding during production, helping to improve production efficiency. In addition, the expansion of the outer diameter of the connecting part can improve the overall strength of the fixing part and ensure the reliability of the connection and fixation of the fixing part.

[0009] In a preferred implementation of a food processor with good shock-absorbing effect, the limiting portion is an annular convex rib extending outward from the bottom end of the connecting portion, and the bottom surface of the annular convex rib abuts against the outer wall of the motor.

[0010] By setting the limiting part as an annular convex rib extending outward from the bottom end of the connecting part, and the bottom surface of the annular convex rib abuts against the outer wall of the motor, when the fixing part is installed in place, the bottom surface of the annular convex rib abuts against the outer wall of the motor, thereby achieving circumferential positioning of the fixing part and preventing the fixing part from being further tightened. Preferably, the bottom wall of the shock-absorbing sleeve abuts against the top wall of the annular convex rib, thereby achieving positioning of the shock-absorbing sleeve and the entire shock-absorbing part, ensuring the stability of the position of the shock-absorbing part, and further ensuring its shock-absorbing effect.

[0011] In a preferred implementation of a food processor with good shock absorption effect, the food processor also includes an air guide cover arranged below the motor, the air guide cover is supported below the motor bracket, and an isolation pad is provided between the air guide cover and the motor bracket.

[0012] By providing an isolation pad between the air guide cover and the motor bracket, the motor bracket and the air guide cover are in flexible contact, so that the vibration energy transmitted to the motor bracket during the rotation of the motor can be buffered and shock-absorbed under the action of the isolation pad, effectively reducing the transmission of the motor bracket to the air guide cover, avoiding direct contact between the motor bracket and the air guide cover, resulting in relative collision with the air guide cover when the motor bracket vibrates and generates noise, and transmitting the vibration to the air guide cover, causing greater vibration of the whole machine, further improving the shock absorption and noise reduction effect of the whole machine.

[0013] In a preferred implementation of a food processor with good shock absorption effect, a support surface is provided on the top of the air guide cover, an isolation pad is provided on the support surface, the support surface is provided with an annular rib extending upward, and the isolation pad is sleeved on the outside of the annular rib.

[0014] By providing the support surface with annular ribs extending upward and the isolation pad being sleeved on the outside of the annular ribs, the radial limiting effect of the support surface on the isolation pad is achieved, thereby ensuring the reliable stability of the position of the isolation pad, thereby avoiding lateral displacement of the isolation pad after long-term use, resulting in poor shock absorption effect of the isolation pad or even failure to achieve shock absorption, thereby ensuring its buffering and shock absorption effect.

[0015] In a preferred implementation of a food processor with good shock absorption effect, the isolation pad includes an isolation ring clamped between the air guide cover and the motor bracket and a positioning ring extending upward to the inner side of the motor bracket, and the outer side wall of the positioning ring abuts against the inner side wall of the motor bracket.

[0016] By configuring the isolation pad to include an isolation ring clamped between the air guide cover and the motor bracket and a positioning ring extending upward to the inner side of the motor bracket, and the outer wall of the positioning ring abuts against the inner wall of the motor bracket, the isolation pad can not only isolate and dampen the motor bracket and the air guide cover, but also achieve the positioning function of the motor bracket and the isolation pad with the help of the positioning ring, thereby ensuring the accuracy of the connection between the motor bracket and the isolation pad, and further ensuring the shock-absorbing effect of the isolation pad.

[0017] In a preferred implementation of a food processor with good shock-absorbing effect, an outer side wall of the shock-absorbing sleeve is provided with an annular rib extending outward, and the annular rib abuts against the hole wall of the avoidance hole.

[0018] By providing the outer wall of the shock-absorbing sleeve with an annular rib extending outward, and the annular rib abutting against the hole wall of the avoidance hole, on the one hand, with the help of the structural characteristics of the annular rib, when the vibration transmitted from the motor to the fixing part is transmitted to the shock-absorbing sleeve, the larger elastic deformation of the annular rib can greatly improve the buffering and shock-absorbing effect of the shock-absorbing sleeve, and further improve the shock-absorbing effect; on the other hand, it can improve the tightness of the fit between the shock-absorbing sleeve and the avoidance hole, and then further improve the coaxiality of the fixing part and the avoidance hole, thereby ensuring the coaxiality of the motor and the motor bracket and improving the stability of operation.

[0019] In a preferred implementation of a food processor with good shock absorption effect, a flexible pad is clamped between the motor bracket and the motor.

[0020] By clamping a flexible pad between the motor bracket and the motor, flexible isolation of the motor bracket and the motor is achieved, so that the vibration generated when the motor rotates is reduced by the buffering and shock absorption of the flexible pad and is transmitted to the motor bracket, thereby reducing the transmission of the vibration on the motor bracket to the cup body, achieving the effect of shock absorption and noise reduction.

[0021] In a preferred implementation of a food processor with good shock-absorbing effect, the flexible pad is provided with a through hole for the threaded portion to pass through, and the motor is provided with a positioning rib extending outward and abutting against the inner wall of the through hole.

[0022] By providing the motor with positioning ribs extending outward and abutting against the inner wall of the through hole, the flexible pad can be positioned radially by the positioning ribs, thereby ensuring the position reliability of the flexible pad, thereby ensuring its buffering and shock absorbing effect, and avoiding the situation where the flexible pad is displaced after long-term use, resulting in a deterioration of its shock absorbing effect.

[0023] In a preferred implementation of a food processor with good shock absorption effect, the motor includes a winding coil, and a side wall of the motor bracket is provided with a ventilation hole, and a lateral projection of the ventilation hole at least partially overlaps with the winding coil.

[0024] By providing a vent on the side wall of the motor bracket, and the lateral projection of the vent at least partially overlaps with the winding coil, when the airflow flows inward through the vent, it can blow directly onto the winding coil, thereby achieving direct and effective heat dissipation of the winding coil, which helps to improve the heat dissipation effect of the motor.

[0034] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0035] like Figures 1 to 5 As shown, the utility model provides a food processing machine with good shock absorption effect, comprising a cup body 1 with a crushing chamber, a motor 2 arranged at the bottom of the cup body 1, a rotating shaft driven by the motor 2 passes through the bottom wall of the cup body 1 and extends into the cup body 1, a crushing device 4 is arranged at the end of the rotating shaft, the food processing machine also includes a motor bracket 3 and a fixing member 6 that fixes the motor bracket 3 to the motor 2, a shock absorbing member 7 is arranged between the fixing member 6 and the motor bracket 3 to isolate the two, the fixing member 6 includes a threaded portion 62 arranged at the front end, a limiting portion 61 arranged at the rear end and a connecting portion 63 connecting the two, the threaded portion 62 is fastened to the motor 2, the limiting portion 61 is located at the outside of the motor bracket 3, the motor bracket 3 is provided with an avoidance hole 31, the shock absorbing member 7 includes a shock absorbing ring 71 isolated between the limiting portion 61 and the motor bracket 3 and a shock absorbing sleeve 72 isolated between the connecting portion 63 and the avoidance hole 31, a protrusion 64 protruding outward relative to the threaded portion 62 is arranged on the connecting portion 63, and when the fixing member 6 is installed in place, the protrusion 64 abuts against the outer wall of the motor 2.

[0036] The present application provides a shock absorbing member 7 between the fixing member 6 and the motor bracket 3 to isolate the two, so that after the motor bracket 3 is fixedly connected with the motor 2 through the fixing member 6, the fixing member 6 and the motor bracket 3 are flexibly isolated through the shock absorbing member 7, so that when the food processing machine is working, the vibration generated by the high-speed rotation of the motor 2 is transmitted to the motor bracket 3 through the fixing member 6, and the vibration is reduced by the shock absorbing member 7, which effectively reduces the transmission of the vibration to the motor bracket 3, and then reduces the transmission of the vibration on the motor bracket 3 to the cup body 1, and achieves the effect of shock reduction and noise reduction. At the same time, the shock absorbing member 7 includes a shock absorbing ring 71 isolated between the limiting part 61 and the motor bracket 3 and a shock absorbing sleeve 72 isolated between the connecting part 63 and the avoidance hole 31, which realizes the all-round isolation of the motor bracket 3 and the fixing member 6, further reduces the transmission of the vibration to the motor bracket 3, and at the same time, the shock absorbing sleeve 72 can limit the central positioning of the fixing member 6, thereby ensuring the coaxiality of the fixing member 6 and the avoidance hole 31, thereby ensuring the coaxiality of the motor 2 and the motor bracket 3, and improving the stability of operation.

[0037] In addition, a protrusion 64 protruding outward relative to the threaded portion 62 is provided on the connecting portion 63. When the fixing member 6 is installed in place, the protrusion 64 abuts against the outer wall of the motor 2. Compared with the existing method in which the lower part of the fixing member 6 is entirely a threaded portion 62, the protrusion 64 can abut against the outer wall of the motor 2 when the fixing member 6 is installed in place, thereby realizing the axial positioning of the fixing member 6. On the one hand, it can enable the assembler to feel that the fixing member 6 has been installed in place and does not need to be further tightened; on the other hand, under the limiting effect of the outer wall of the motor 2, the fixing member 6 cannot be further tightened, so that the fixing member 6 can be fixed in a reasonable limiting space during assembly, avoiding the fixing member 6 from being screwed too tightly during assembly, resulting in excessive squeezing of the flexible member, especially the shock-absorbing ring 71 by the fixing member 6, causing the shock-absorbing ring 71 to be unable to provide buffering and shock-absorbing, and then causing the motor 2 to transmit greater vibration to the motor bracket 3, which can ensure the shock-absorbing effect of the shock-absorbing member 7 and reduce the generation of vibration noise.

[0038] It should be noted that the present application does not specifically limit the structure of the protrusion 64, which may be any one of the following embodiments:

[0040] By setting the step surface such that the outer diameter of the connection part 63 is enlarged relative to the threaded part 62 to form a step surface facing the connection part 63, when the fixing part 6 is installed in place, the step surface abuts against the outer wall of the motor 2, thereby achieving axial positioning of the fixing part 6 and preventing the fixing part 6 from being further tightened. At the same time, the enlargement of the outer diameter of the connection part 63 can realize the molding of the protrusion 64, which has a simple structure and is convenient for demolding during production, helping to improve production efficiency. In addition, the enlargement of the outer diameter of the connection part 63 can improve the overall strength of the fixing part 6 and ensure the reliability of the connection and fixation of the fixing part 6.

[0041] Embodiment 2: The limiting portion 61 is an annular convex rib extending outward from the bottom end of the connecting portion 63 , and the bottom surface of the annular convex rib abuts against the outer wall of the motor 2 .

[0042] By setting the limiting portion 61 as an annular convex rib extending outward from the bottom end of the connecting portion 63, and the bottom surface of the annular convex rib abuts against the outer wall of the motor 2, when the fixing member 6 is installed in place, the bottom surface of the annular convex rib abuts against the outer wall of the motor 2, thereby achieving circumferential positioning of the fixing member 6 and preventing the fixing member 6 from being further tightened. Preferably, the bottom wall of the shock-absorbing sleeve 72 abuts against the top wall of the annular convex rib, thereby achieving positioning of the shock-absorbing sleeve 72 and the entire shock-absorbing member 7, ensuring the stability of the position of the shock-absorbing member 7, and further ensuring its shock-absorbing effect.

[0043] It should be further explained that the present application does not specifically limit the structure of the annular rib in this embodiment. It can be a complete circle around the connecting portion 63, or it can be a plurality of intermittent ribs around the connecting portion 63, which will not be described in detail here.

[0046] Furthermore, if Figure 2 As shown, a support surface 51 is provided on the top of the air guide cover 5 , and the isolation pad 9 is provided on the support surface 51 . The support surface 51 is provided with an annular rib 511 extending upward, and the isolation pad 9 is sleeved on the outside of the annular rib 511 .

[0047] By providing the support surface 51 with an upwardly extending annular rib 511 and the isolation pad 9 being sleeved on the outside of the annular rib 511, the radial limiting effect of the support surface 51 on the isolation pad 9 is achieved, thereby ensuring the reliable stability of the position of the isolation pad 9, thereby avoiding the lateral displacement of the isolation pad 9 after long-term use, resulting in the isolation pad 9 The shock-absorbing effect becomes worse or even cannot be achieved, thereby ensuring its buffering and shock-absorbing effect.

[0048] It should be noted that the present application does not specifically limit the structure of the isolation pad 9. As a preferred embodiment of the present application, the isolation pad 9 includes an isolation ring clamped between the air guide cover 5 and the motor bracket 3 and a positioning ring extending upward to the inner side of the motor bracket 3, and the outer wall of the positioning ring abuts against the inner wall of the motor bracket 3.

[0049] By configuring the isolation pad 9 to include an isolation ring clamped between the air guide cover 5 and the motor bracket 3 and a positioning ring extending upward to the inner side of the motor bracket 3, and the outer wall of the positioning ring abuts against the inner wall of the motor bracket 3, the isolation pad 9 can not only isolate and shock-absorb the motor bracket 3 and the air guide cover 5, but also achieve the positioning function of the motor bracket 3 and the isolation pad 9 with the help of the positioning ring, thereby ensuring the accuracy of the connection between the motor bracket 3 and the isolation pad 9, and further ensuring the shock-absorbing effect of the isolation pad 9.

[0050] As a preferred implementation of the present application, Figure 4 As shown, the outer side wall of the shock-absorbing sleeve 72 is provided with an annular rib 511 extending outward, and the annular rib 511 abuts against the hole wall of the avoidance hole 31 .

[0051] By providing the outer side wall of the shock-absorbing sleeve 72 with an outwardly extending annular rib 511, and the annular rib 511 abuts against the hole wall of the avoidance hole 31, on the one hand, with the help of the structural characteristics of the annular rib 511, when the vibration transmitted from the motor 2 to the fixing member 6 is transmitted to the shock-absorbing sleeve 72, the annular rib 511 is greatly elastically deformed, thereby greatly improving the buffering and shock-absorbing effect of the shock-absorbing sleeve 72, and further improving the shock-absorbing effect; on the other hand, it can improve the tightness of the fit between the shock-absorbing sleeve 72 and the avoidance hole 31, and further improve the coaxiality between the fixing member 6 and the avoidance hole 31, thereby ensuring the coaxiality of the motor 2 and the motor bracket 3, and improving the stability of operation.

[0052] As a preferred implementation of the present application, Figure 4 As shown, a flexible pad 8 is clamped between the motor bracket 3 and the motor 2 .

[0053] By clamping a flexible pad 8 between the motor bracket 3 and the motor 2, flexible isolation of the motor bracket 3 and the motor 2 is achieved, so that the vibration generated when the motor 2 rotates is reduced by the buffering and shock absorption of the flexible pad 8 and is transmitted to the motor bracket 3, thereby reducing the transmission of the vibration on the motor bracket 3 to the cup body 1, achieving the effect of shock absorption and noise reduction.

[0054] Furthermore, if Figure 4 As shown, the flexible pad 8 is provided with a through hole for the threaded portion 62 to pass through, and the motor 2 is provided with a positioning rib 21 extending outward and abutting against the inner wall of the through hole.

[0055] By providing the motor 2 with a positioning rib 21 extending outward and abutting against the inner wall of the through hole, the flexible pad 8 can be positioned radially by the positioning rib 21, thereby ensuring the position reliability of the flexible pad 8, and further ensuring its buffering and shock absorbing effect, thereby avoiding the situation where the flexible pad 8 is displaced after long-term use, resulting in a deterioration of its shock absorbing effect.
