Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a clutch and a food processor. Background Technology

[0002] With the continuous improvement of people's living standards, many different types of food processors have appeared on the market. The functions of food processors mainly include, but are not limited to, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. Food processors can include soy milk makers, blenders, or high-speed blenders—machines that pulverize and mix food. Existing food processors suffer from problems such as vibration and high noise levels during operation, and the clutches used in food processors are prone to breakage during operation. Utility Model Content

[0003] This application provides a clutch and a food processor that can reduce vibration and noise during operation, and can increase the strength of the clutch so that it is not easy to break during operation.

[0004] This application provides a clutch. The clutch includes: a rigid frame, comprising a frame body and transmission teeth protruding from the frame body; and a soft covering layer covering the rigid frame, the soft covering layer comprising a frame covering layer covering the frame body and a transmission covering layer covering the transmission teeth, and the soft covering layer is made of a soft material. When the food processor starts working, the motor starts, and the motor's output shaft begins to rotate, causing impact between the clutch and the clutch. Because the soft covering layer covers the rigid frame, it can reduce vibration and noise. Furthermore, by covering the rigid frame 10 with a soft covering layer, the overall strength of the clutch can be increased, preventing the clutch from breaking during operation.

[0005] Furthermore, the transmission gear includes a transmission surface, and the transmission covering layer includes an abutment layer covering the transmission surface, wherein the abutment layer is provided with a plurality of support ribs. Because the abutment layer is provided with a plurality of support ribs, and these support ribs have a certain degree of elasticity, they will deform under stress, preventing the abutment layer from tearing during operation, thus making the structure more stable and reliable.

[0006] Furthermore, a reinforcing portion is provided at the connection between the skeleton covering layer and the abutment layer. Because the reinforcing portion is provided at the connection between the skeleton covering layer and the abutment layer, the stress at the connection can be eliminated or reduced, preventing the connection from tearing during operation, resulting in a more stable and reliable structure.

[0007] Furthermore, the reinforcing portion includes a sloped or arc-shaped surface connected to the skeleton covering layer and the abutment layer. This results in a reliable structure and simple manufacturing.

[0008] Furthermore, the thickness of the flexible covering layer ranges from 1.2 mm to 4 mm. This provides good shock absorption without increasing costs.

[0009] Furthermore, the thickness of the skeleton body is not less than 0.8 mm. This ensures that the rigid skeleton has high strength.

[0010] Furthermore, the frame body includes perforations, and the frame covering layer includes a first portion covering the upper surface of the frame body, a second portion covering the lower surface of the frame body, and a third portion passing through the perforations, wherein the third portion is connected to the first portion and the second portion. In this way, the frame covering layer and the frame body are more tightly bonded, making the clutch structure more reliable and extending its service life.

[0011] Furthermore, the rigid skeleton includes a plurality of transmission teeth arranged circumferentially along the skeleton body, and the perforation includes a first perforation disposed between two adjacent transmission teeth. This further strengthens the bond between the skeleton covering layer and the skeleton body, thereby making the clutch structure more reliable and extending its service life.

[0012] Furthermore, the perforation includes a second perforation radially disposed inside the transmission tooth. This further ensures a tighter bond between the skeleton covering layer and the skeleton body.

[0013] Furthermore, the soft coating layer is applied to the rigid skeleton via an overmolding process or a secondary vulcanization process. This simplifies manufacturing.

[0014] This application provides a food processor. The food processor includes: a base, comprising a base and a support seat disposed on the base, the base housing a motor; a mixing cup assembly assembled on the base, the mixing cup assembly including a mixing cup and a mixing blade assembly disposed at the bottom of the mixing cup, the mixing blade assembly including a blade shaft, blades, and a clutch as described above, the output shaft of the motor having a mating clutch cooperating with the clutch; and a cover assembled on the support seat, the cover covering the mixing cup assembly.

[0015] Furthermore, the frame body is provided with a mounting hole that mates with the cutter shaft and a boss surrounding the mounting hole. The boss protrudes from the soft covering layer, and the cutter shaft is provided with a stepped portion that abuts against the boss. Through the abutting engagement between the boss and the stepped portion, the clutch can be stably fixed to the cutter shaft, making the clutch more stable and reliable during operation.

[0016] Furthermore, the skeleton body is fixedly connected to the cutter shaft by welding or a threaded structure. This allows for convenient and reliable fixing of the clutch to the cutter shaft. Attached Figure Description

[0024] Please see Figures 1 to 5The food processor 100 can be used to make soy milk, rice paste, juice, etc. The food processor 100 includes a base 30, a blending cup assembly 40, a lid 50, and a motor (not shown).

[0025] The base 30 includes a base 31 and a support 32 disposed on the base 31, and a motor is disposed inside the base 31. The support 32 and the base 31 can be integrally formed, or they can be formed separately and then assembled together.

[0026] The mixing cup assembly 40 is assembled on the base 31. The mixing cup assembly 40 includes a mixing cup 41, a heating plate 43 disposed at the bottom of the mixing cup 41, and a mixing blade assembly. The mixing blade assembly includes a blade shaft 421, blades, and a clutch 423. The output shaft of the motor is provided with a docking clutch that engages with the clutch 423. The mixing cup 41 is used to hold food ingredients, the heating plate 43 is used to heat the food ingredients in the mixing cup 41, and the mixing blade assembly is used to stir and pulverize the food ingredients in the mixing cup 41.

[0027] The clutch 423 includes a rigid frame 10 and a soft covering layer 20. The rigid frame 10 includes a frame body 11 and transmission teeth 12 protruding from the frame body 11. The rigid frame 10 can be made of metal, hard plastic, etc., and is not limited to these.

[0028] A soft covering layer 20 covers the rigid frame 10. The soft covering layer 20 includes a frame covering layer 21 covering the frame body 11 and a transmission covering layer 22 covering the transmission gear 12. The soft covering layer 20 is made of a soft material. The material of the soft covering layer 20 can be rubber, silicone, or other materials, but is not limited to these.

[0029] The lid 50 is assembled to the support base 32 and covers the mixing cup assembly 40. In one embodiment, the lid 50 is rotatably assembled to the support base 32. In another embodiment, the lid 50 is detachably assembled to the support base 32.

[0030] When the food processor 100 starts working, the motor starts and the output shaft of the motor begins to rotate. Impact will occur between the engagement clutch and the clutch 423. Since the soft covering layer 20 covers the rigid frame 10, it can play a role in shock absorption and noise reduction. In addition, by covering the rigid frame 10 with the soft covering layer 20, the overall strength of the clutch 423 can be increased, preventing the clutch 423 from breaking during operation.

[0031] The transmission gear 12 includes a transmission surface 125, and the transmission covering layer 22 includes an abutment layer 225 covering the transmission surface 125. The abutment layer 225 is provided with a plurality of support ribs 226. Because the abutment layer 225 is provided with a plurality of support ribs 226, and the support ribs 226 have a certain degree of elasticity, they will deform under force, preventing the abutment layer 225 from being torn during operation, making the structure more stable and reliable.

[0032] A reinforcing part 23 is provided at the connection between the skeleton covering layer 21 and the abutment layer 225. Because the reinforcing part 23 is provided at the connection between the skeleton covering layer 21 and the abutment layer 225, the stress at the connection between the skeleton covering layer 21 and the abutment layer 225 can be eliminated or reduced, and the connection between the skeleton covering layer 21 and the abutment layer 225 can be prevented from being torn during operation, making the structure more stable and reliable.

[0033] The reinforcing part 23 includes a sloped or arc-shaped surface connected to the skeleton covering layer 21 and the abutment layer 225. This results in a reliable structure and simple manufacturing.

[0034] Preferably, the thickness of the flexible covering layer 20 is between 1.2 mm and 4 mm. This provides good shock absorption without increasing costs.

[0035] In some embodiments, the thickness of the soft covering layer 20 can be 1.2 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, or any value between any two of the above.

[0036] Preferably, the thickness of the skeleton body 11 is not less than 0.8 mm. This ensures that the rigid skeleton 10 has high strength.

[0037] In some embodiments, the thickness of the skeleton body 11 can be 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3 mm, or any value between any two adjacent values ​​mentioned above, and is not limited thereto.

[0038] The frame body 11 includes a perforation 111. The frame covering layer 21 includes a first portion 211 covering the upper surface of the frame body 11, a second portion 212 covering the lower surface of the frame body 11, and a third portion 213 passing through the perforation 111. The third portion 213 is connected to the first portion 211 and the second portion 212. In this way, the frame covering layer 21 and the frame body 11 are more tightly bonded, making the clutch 423 structure more reliable and its service life longer. The shape, size, and position of the perforation 111 can be set according to specific circumstances and are not limited here.

[0039] The rigid frame 10 includes a plurality of transmission teeth 12 arranged circumferentially along the frame body 11, and the perforation 111 includes a first perforation 1111 disposed between two adjacent transmission teeth 12. This further strengthens the bond between the frame covering layer 21 and the frame body 11, thereby making the clutch 423 structure more reliable and extending its service life.

[0040] The perforation 111 includes a second perforation 1112 radially disposed inside the transmission tooth 12. This further strengthens the bond between the skeleton covering layer 21 and the skeleton body 11. In the illustrated embodiment, the number of transmission teeth 12 is the same as the number of second perforations 1112, but this is not a limitation.

[0041] In some embodiments, the soft coating layer 20 is coated onto the rigid skeleton 10 by an overmolding process or a secondary vulcanization process. This facilitates manufacturing.

[0042] The frame body 11 is provided with a mounting hole 119 that mates with the cutter shaft 421 and a boss 112 surrounding the mounting hole 119. The boss 112 protrudes from the soft covering layer 20. The cutter shaft 421 is provided with a stepped portion 4211 that abuts against the boss 112. Through the abutting engagement between the boss 112 and the stepped portion 4211, the clutch 423 can be stably fixed on the cutter shaft 421, making the clutch 423 more stable and reliable during operation.

[0043] The skeleton body 11 is fixedly connected to the cutter shaft 421 by welding or threaded connection. In this way, the clutch 423 can be conveniently and reliably fixed to the cutter shaft 421.
