Description

Technical Field

[0001] This utility model relates to the field of food processor technology, and more specifically, to a motor vibration damping pad and a food processor using the same. Background Technology

[0002] Currently, with social progress and technological development, high-speed blenders are increasingly widely used in households. However, the noise level of these blenders has been a persistent problem for many users. Existing high-speed blenders have reduced their noise levels from an early 90dB(A) to the current industry standard of 75dB(A) through various noise reduction, sound insulation, vibration damping, and sound absorption technologies, providing a relatively quiet user experience. However, after a long period of technological updates and iterations, the threshold for noise reduction has gradually increased. Once the noise level reaches a certain point, further technological breakthroughs in noise reduction become particularly difficult. Therefore, developing an efficient and comprehensive vibration reduction technology has become crucial for improving product performance.

[0003] To address this issue, patents CN109004789B and CN109004788B disclose a motor vibration damping pad. This pad is designed to significantly dissipate vibration energy, effectively reducing the vibration amplitude and frequency of the motor system, thereby eliminating noise caused by motor vibration. However, existing motor vibration damping pads typically employ a simple mounting structure, which lacks space for deformation buffering. For example, the second flange end face of the damping pad is usually flat, and the end face of the fixing component is also flat, resulting in direct contact between the two planes and a lack of buffering space for deformation. Therefore, this type of damping pad can only achieve partial vibration damping and cannot achieve comprehensive vibration damping.

[0004] In summary, while some vibration damping pads currently on the market can reduce motor system vibration to some extent, their simple installation structure and lack of necessary deformation buffer space limit the comprehensiveness and effectiveness of their vibration damping effect. Therefore, developing a new type of vibration damping pad that can effectively overcome these shortcomings is of great significance for improving the overall performance of high-speed blenders.

[0018] 1. In this solution, multi-dimensional vibration reduction is achieved by setting buffer sections in different directions on the vibration damping pad body. The first and third buffer sections provide axial buffering, effectively absorbing axial vibration during motor operation; while the second and fourth buffer sections play a role in the vertical direction, reducing vertical vibration, forming an all-round buffer structure, which enables the vibration damping pad to better adapt to vibration in different directions, thereby significantly improving the vibration reduction effect, reducing noise, and improving the overall performance and user experience of the blender.

[0019] 2. In this design, a first annular groove and a second buffer rib are incorporated to enhance the damping capacity of the damping pad body along the axial direction of the mounting hole, effectively absorbing axial vibrations during motor operation. The annular ribs on the upper and lower support surfaces further improve the vertical stability of the damping pad, ensuring smooth operation of the food processor. The even distribution of the lower boss and the design of the first clearance groove not only increase the strength and rigidity of the lower flange but also provide more dispersion paths for vibrations, reducing the possibility of vibrations being transmitted to the food processor base. Raised ribs on the outer circumference of the cylinder form an effective fourth buffer, enhancing the damping effect of the damping pad in the circumferential direction. This allows the entire damping pad to provide comprehensive buffer protection in three-dimensional space, significantly reducing noise during food processor operation and further improving the user experience.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1 As shown, a vibration damping pad for a motor 31 is provided in the first embodiment of this utility model. The vibration damping pad body 33 includes a cylindrical body 331. The upper and lower ends of the cylindrical body 331 are respectively provided with an upper flange 332 and a lower flange 333. A mounting hole 335 is provided through the cylindrical body 331. A first buffer portion is provided on the top surface of the upper flange 332, a second buffer portion is provided on the inner end surface of the mounting hole 335, a third buffer portion is provided on the bottom end surface of the lower flange 333, and a fourth buffer portion is provided on the outer end surface of the cylindrical body 331. Each buffer portion forms a protrusion or depression on its end surface to leave a buffer zone. With the axis of the mounting hole 335 as the reference line, the first buffer portion and the third buffer portion provide axial buffering for the vibration damping pad body 33 along the reference line, and the second buffer portion and the fourth buffer portion provide vertical buffering for the vibration damping pad body 33 along the reference line. Multiple buffer zones constitute an all-round buffering structure.

[0036] Furthermore, such as Figure 1 , 2As shown in Figure 3, in this embodiment, the top of the upper flange 332 of the damping pad body 33 is provided with at least one first annular groove 334 to form a first buffer part, and the inner circumferential wall of the cylinder 331 is provided with at least two annular ribs 3310 to form a second buffer part. The upper flange 332 has an upper support surface 3321, and the lower flange 333 has a lower support surface 3331. Annular ribs 3310 are provided on the inner wall of the cylinder 331 corresponding to the upper support surface 3321 and the lower support surface 3331. The bottom surface of the lower flange 333 is provided with a lower boss 337 to form a third buffer part. Multiple lower bosses 337 are evenly arranged and a first clearance groove 338 is left between adjacent lower bosses 337. Multiple ribs 336 are axially evenly distributed on the outer circumferential wall of the cylinder 331 to form a fourth buffer part. In other words, buffer zones are provided at the upper and lower ends, as well as the inner and outer rings, of the vibration damping pad body 33. These buffer zones not only enhance the structural strength of the vibration damping pad body 33 but also significantly improve its buffering performance. The ring ribs 3310 at the upper support surface 3321 and the lower support surface 3331 ensure stable support of the vibration damping pad body 33 during installation, while also increasing the buffer area and improving the overall buffering effect. Figure 4 As shown, multiple first clearance grooves 338 are provided on the lower boss 337, which not only reduces the weight of the damping pad body 33, but also helps to optimize the buffering performance, allowing vibration energy to be more evenly distributed to each buffer zone. The raised ribs 336 on the outer circumference of the cylinder 331, i.e., the fourth buffer part, enhance the outer ring structure of the damping pad body 33, and at the same time provide an additional buffer layer to effectively resist vibration interference from the outside. This all-round buffering structure design of this embodiment enables the damping pad body 33 to provide excellent buffering performance in multiple directions, thereby ensuring that the food processor remains stable during operation and extending its service life.

[0037] To enhance the buffering effect and stability of the vibration damping pad body 33, in this embodiment, the number of first annular grooves 334 is preferably two, and the two first annular grooves 334 are symmetrically arranged about the axis of the mounting hole 335. This design allows the motor 31 to be installed more smoothly, reducing vibration and noise. Simultaneously, the annular ribs 3310 also increase the structural strength of the cylinder 331 and improve the durability of the vibration damping pad. Furthermore, to further optimize the buffering effect, the annular ribs 3310 of the second and fourth buffer sections can be designed as wavy or spiral shapes. This increases the elasticity of the buffer section, allowing the vibration damping pad to better absorb and disperse energy when subjected to impact, thereby achieving a better vibration damping effect. At the same time, the wavy or spiral annular ribs 3310 also increase the surface area of ​​the cylinder 331, improving heat dissipation performance and extending the service life of the vibration damping pad.

[0038] It should be noted that the vibration damping pad body 33 in this embodiment is generally made of a material with an elastomer, such as silicone, rubber, or TPE. Testing has shown that the harder the elastomer material, the more stably the motor assembly 3 is fixed, but the easier it is for the vibration energy of the motor 31 to be transmitted to the main unit, resulting in a poorer vibration damping effect. Conversely, the softer the elastomer material, the more buffered the motor assembly 3 is fixed, and the less likely the vibration energy of the motor 31 is to be transmitted to the main unit, resulting in a better vibration damping effect, but the motor 31 is less stable. Therefore, a vibration damping pad that is neither too hard nor too soft needs to be selected. Experimental testing shows that if the vibration damping pad hardness is below Shore A 30A, the vibration damping effect is good, but the machine shakes more, resulting in a poor user experience. If Shore A 45A or higher is selected, the machine is more stable, but the vibration damping effect is poor. Based on actual testing, this embodiment preferably uses an elastomer with a hardness of 35A to 45A for the vibration damping pad body.

[0039] like Figure 5 As shown, the axial distance between the ring rib 3310 located on the upper support surface 3321 and the upper support surface 3321 is L1, and the axial distance between the ring rib 3310 located on the lower support surface 3331 and the lower support surface 3331 is L2. The width of the ring rib 3310 is a. L1 and L2 are equal and not zero. The values ​​of L1 and L2 are both less than 0.5a, and the value of a is from 0.5mm to 1mm. The inner diameter of the vibration damping pad body 33 is small at both ends and large in the middle. The mounting hole 335 corresponds to... The inner diameter at the upper flange 332 is D1, the inner diameter at the mounting hole 335 corresponding to the lower flange 333 is D2, and the inner diameter between the two annular ribs 3310 at the upper support surface 3321 and the lower support surface 3331 corresponding to the mounting hole 335 is D3. D1 and D2 are equal and both D1 and D2 are less than D3. The width of the first annular groove 334 is 1.2mm to 1.5mm and the depth is 1mm to 1.2mm. The depth of the first clearance groove 338 is 1.5mm to 2mm.

[0040] Furthermore, the arrangement of the first annular groove 334 and the first clearance groove 338 effectively avoids interference between the motor assembly 3 and the vibration damping pad body 33 during installation, ensuring smooth installation. In this embodiment, all the inner and outer perimeters of the buffer zones combine to form an all-around buffer and vibration damping system between the bracket 32 ​​and the fixed column 11, thus reducing noise by 2 to 3 dB(A) compared to existing technologies.

[0041] like Figure 6As shown, this is a vibration damping pad for a motor 31 provided in the second embodiment of the present invention. The difference from the first embodiment is that the top of the upper flange 332 of the damping pad body is provided with at least one upper boss 3311 to form a first buffer portion. Multiple upper bosses 3311 are evenly arranged, and a second clearance groove 3312 is left between adjacent upper bosses 3311.

The upper flange 332 has an upper support surface. 3321, the lower flange 333 has a lower support surface 3331, and the inner wall of the cylinder 331 corresponding to the upper support surface 3321 and the lower support surface 3331 is provided with ring ribs 3310. The bottom surface of the lower flange 333 is provided with a lower boss 337 to form a third buffer part. Multiple lower bosses 337 are evenly arranged and a first clearance groove 338 is left between adjacent lower bosses 337. Multiple ribs 336 are axially evenly distributed on the outer circumferential wall of the cylinder 331 to form a fourth buffer part.

[0042] like Figure 7 As shown, a motor 31 vibration damping pad is provided in the third embodiment of this utility model. The difference from the second embodiment is that at least one second annular groove 33111 is opened on the upper boss 3311 of the vibration damping pad body, and the center of the second annular groove 33111 is set on the axis of the mounting hole 335.

[0043] like Figure 8 As shown, this is a vibration damping pad for a motor 31 provided in the fourth embodiment of the present invention. The difference from the first embodiment is that the top of the upper flange 332 of the damping pad body is provided with protrusions 3313 to form a first buffer portion. Multiple protrusions 3313 are grouped together, and multiple groups are evenly distributed on the top of the upper flange 332. A third clearance groove 339 is left between adjacent groups.

[0044] Furthermore, the protrusions 3313 are columnar and each group has at least 3 protrusions 3313 for the motor assembly. The protrusions 3313 in each group are arranged in a straight line and the extension of the line intersects the axis of the mounting hole 335.

[0045] like Figures 9 to 11As shown, a food processor according to the fifth embodiment of this utility model includes a main unit assembly 1 and a cup assembly 2. The cup assembly 2 is mounted on the main unit assembly 1. A motor assembly 3 is disposed inside the main unit assembly 1. The motor assembly 3 includes a motor 31 and a bracket 32. The motor 31 is fixedly mounted in the middle of the bracket 32. Mounting holes 321 are formed around the bracket 32.

The lower ends of the hole 321 abut against each other. The top of the main unit 1 is provided with a fixing post 11 corresponding to the mounting hole 321. The bottom of the fixing post 11 is connected to a plug post 111 for insertion into the mounting hole 335. The outer diameter of the plug post 111 is smaller than the outer diameter of the fixing post 11. When the plug post 111 is inserted into the mounting hole 335, the bottom surface of the fixing post 11 abuts against the top surface of the damping pad body 33. At the same time, one end of the plug post 111 extends out from the mounting hole 335 and is fixedly connected to the damping pad body 33 through the washer 12 and screw 13.

[0046] In this embodiment, a single shock-absorbing pad body is provided with multiple buffer zones. The bottom surface of the fixing post 11 and the first annular groove 334 form a first buffer zone 3301.

The gap between the outer wall of the insertion post 111 and the mounting hole 335 corresponding to the inner wall of the cylinder 331 is a second buffer zone 3302. The gap between the outer wall of the insertion post 111 and the mounting hole 335 corresponding to the upper flange 332 is... The gap between the inner walls is the fourth buffer zone 3304. The second buffer zone 3302 and the fourth buffer zone 3304 are both 0.2mm to 0.3mm. The first clearance groove 338, together with the outer wall of the gasket 12 and the insert 111, forms the fifth buffer zone 3305. The gap between the outer wall of the cylinder 331 and the inner wall of the mounting hole 321 is the sixth buffer zone 3306. The sixth buffer zone 3306 is 0.2mm to 0.3mm. The protruding rib 336 of the cylinder 331 and the mounting hole 321 form an interference fit, and the interference amount is 0.1mm to 0.3mm.

[0047] In this embodiment, the vibration damping pad body 33 can effectively absorb and disperse vibration energy when the motor 31 is working, reducing the transmission of vibration from the motor assembly 3 to other parts of the food processor, thereby improving the stability and service life of the food processor. Furthermore, the multiple buffer zones enhance the vibration damping effect, enabling it to handle vibrations of different frequencies and amplitudes, ensuring smoother and quieter operation of the food processor. Simultaneously, the fit between the insertion post 111 and the mounting hole 335, as well as the fixing method of the gasket 12 and screw 13, ensures that the vibration damping pad body 33 is securely installed on the main unit assembly 1, preventing loosening or detachment, further improving the reliability and safety of the food processor.
