Abstract
Description
Technical Field
[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a blender. Background Technology
[0002] Most blenders on the market currently use the shearing force of high-speed rotating blades to break down the cell walls of food, crushing, mixing, and stirring the food into a smooth paste or juice. Examples include the structures disclosed in Chinese invention patent applications CN202411094725.1 (application number CN118648809A, publication number CN118648809A) and CN201610708148.X (application number CN106073448B), which both describe a high-speed blender.
[0003] Existing high-speed blenders suffer from low blending efficiency and incomplete blending. Furthermore, the high-speed rotation of the blades causes the food fluid to rotate rapidly within the blender, creating irregular turbulence that constantly impacts the blender walls and generates noise. In addition, the up-and-down oscillation of the liquid surface during blending also traps a large amount of air, forming bubbles. The bursting of these bubbles also produces noise, resulting in existing high-speed blenders operating at a relatively high noise level. Utility Model Content
[0004] The first technical problem to be solved by this utility model is to provide a blender that can improve the cell wall breaking efficiency in light of the current state of the technology.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a blender, comprising:
[0006] The casing has an internal chamber with a feed inlet;
[0007] A pulverizing blade is located in the chamber and can work under the drive of the drive mechanism to pulverize the food ingredients to be broken from the feed inlet.
[0008] The crushing blade is characterized by comprising:
[0009] The tool holder is connected to the output end of the drive mechanism and can rotate at low speed or high speed around the axis extending vertically from its center under the drive of the drive mechanism.
[0010] At least two blades are arranged at intervals around the aforementioned axis on the periphery of the tool holder, and the tail end of each blade is rotatably mounted on the tool holder. The head end of each blade is a free end extending outward relative to the tool holder. Each blade has a first state of being inclined upward or downward relative to the horizontal surface and a second state of being arranged horizontally.
[0011] An elastic element acts on the blade to ensure that the blade always tends to rotate to a first state; and the elastic element is arranged to elastically deform when the blade holder rotates at high speed, causing the blade to rotate to a second state.
[0012] This invention, through the design of the blade holder, blade, and elastic element, allows the blade to automatically adjust its angle according to the rotational speed of the blade holder. Specifically, when the blade holder rotates at low speed, the blade is in a first state of upward or downward tilt under the action of the elastic element. At this time, the angle of the blade relative to the horizontal plane is relatively large, which is beneficial to increasing the cutting range of the blade and thus improving the cutting efficiency. When the blade holder rotates at high speed, under the action of centrifugal force, the blade overcomes the elastic force of the elastic element and rotates to a second state of horizontal arrangement. At this time, the angle of the blade relative to the horizontal plane becomes smaller, and the diameter area of the blade during cutting becomes larger, which is beneficial to further cell wall breaking and cutting. At the same time, the smaller angle of the blade relative to the horizontal plane reduces the resistance during blade rotation and increases the rotational speed. Therefore, this invention can control the particle size of the food after cell wall breaking and cutting by controlling the rotational speed of the blade holder.
[0013] The "level" mentioned above is relative to "tilt". It can be understood as basically level, but not necessarily a completely level state. For example, the blade may be slightly tilted relative to the horizontal plane, but the tilt angle is much smaller than the tilt angle of the blade in the first state.
[0014] The "low speed" and "high speed" mentioned above are also two relative rotational states, which can be satisfied by the rotational speed at "high speed" being greater than the rotational speed at "low speed".
[0015] Preferably, the tail end of the blade is rotatably connected to the blade holder via a rotating shaft, and the elastic element acts on the rotating shaft.
[0016] The aforementioned elastic components can be metal springs, rubber components, etc.
[0017] Preferably, when the blade is tilted upward relative to the horizontal surface in the first state, the elastic element is a downwardly arched arc-shaped elastic sheet, and the first end of the elastic sheet is constrained together with the rotating shaft, and the second end of the elastic sheet is adjacent to or abuts the lower surface of the blade holder; when the blade is tilted downward relative to the horizontal surface in the first state, the elastic element is an upwardly arched arc-shaped elastic sheet, and the first end of the elastic sheet is constrained together with the rotating shaft, and the second end of the elastic sheet is adjacent to or abuts the upper surface of the blade holder.
[0018] To further improve cell wall breaking efficiency, preferably, the blades are arranged in pairs facing each other, with at least two sets. The blades of the first set are tilted upwards in the first state, and the blades of the second set are tilted downwards in the first state. This increases the cutting range of the blades in the first state, thereby improving the cell wall breaking efficiency.
[0019] Preferably, each blade is arranged in a clockwise or counterclockwise spiral direction.
[0020] Furthermore, the driving mechanism is a motor, with the motor shaft extending upwards and connected to the tool holder.
[0021] In the above embodiments, preferably, it also includes vertically extending ribs, at least two of which are arranged circumferentially at intervals on the inner surface of the cavity.
[0022] When the blender is working, the rotational forces generated by the ribs and blades are perpendicular to each other, effectively blocking the impact of the liquid and preventing large particles from entering, further increasing the difference between the liquid's rotational speed and the blade's rotational speed. This effective cooperation between the ribs and blades increases the probability of successful cutting. Simultaneously, the ribs can be made of silicone or other flexible materials to increase flexibility and reduce the impact noise caused by the high-speed rotation of particles.
[0023] The length and installation height of the ribs can be designed according to actual needs to ensure that particles are blocked from impacting the inner wall of the chamber to the greatest extent without affecting the cell wall breaking efficiency.
[0024] Because a "vortex" phenomenon occurs when liquid rotates at high speed, resulting in a higher liquid level at the outer edge and a lower level in the middle, a baffle plate is preferably included. This baffle plate is horizontally placed within the chamber, with a through hole in its center and notches along its edges corresponding to the positions of the ribs for insertion. The suspended baffle plate automatically adapts to the liquid level and reduces the "vortex" phenomenon, thereby lowering the risk of spillage during beverage preparation.
[0025] Furthermore, the baffle plate gradually slopes downwards from the center to the edge. This design allows the liquid on the outer edge to contact the baffle plate earlier and causes the liquid to converge towards the center along the baffle plate, further reducing the "vortex" phenomenon.
[0026] In the above embodiments, preferably, the housing includes a pot body that is hollow inside and open at the top, and a cover body that is placed on the pot body. The pot body and the cover body together form the above-mentioned cavity, and the open top of the pot body is the feed inlet.
[0027] Compared with existing technologies, the advantages of this invention are as follows: Through the design of the blade holder, blade, and elastic element, the blade can automatically adjust its angle according to the rotational speed of the blade holder. Specifically, when the blade holder rotates at low speed, the blade is in a first state of upward or downward tilt under the action of the elastic element. At this time, the angle of the blade relative to the horizontal plane is relatively large, which is beneficial to increasing the cutting range of the blade and thus improving the cutting efficiency. When the blade holder rotates at high speed, under the action of centrifugal force, the blade overcomes the elastic force of the elastic element and rotates to a second state of horizontal arrangement. At this time, the angle of the blade relative to the horizontal plane becomes smaller, and the diameter area of the blade during cutting becomes larger, which is beneficial to further cell wall breaking and cutting. At the same time, the smaller angle of the blade relative to the horizontal plane reduces the resistance during blade rotation and increases the rotational speed. Therefore, this invention can control the particle size of the food after cell wall breaking and cutting by controlling the rotational speed of the blade holder. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0036] like Figures 1-7 As shown, this is a preferred embodiment of a blender according to the present invention. The blender includes a shell 1, a crushing blade 2, a drive mechanism 3, ribs 4, and a blocking plate 5.
[0037] The housing 1 includes a pot body 1a that is hollow inside and open at the top, and a cover body 1b that is placed on the pot body 1a to open and close the open top. The pot body 1a and the cover body 1b together form the aforementioned chamber 10, and the open top of the pot body 1a is a feeding port for the food to be crushed to enter.
[0038] The pulverizer 2 is located inside the chamber 10 and can operate under the drive of the drive mechanism 3 to pulverize the food ingredients that enter from the feed inlet. The pulverizer 2 includes a blade holder 21, a blade 22, and an elastic element 23.
[0039] The tool holder 21 is connected to the output end of the drive mechanism 3 and can rotate at low speed or high speed around the axis 20 extending vertically from its center under the drive of the drive mechanism 3.
[0040] There are four blades 22, spaced apart around the aforementioned axis 20 on the periphery of the tool holder 21. The tail end 222 of each blade 22 is rotatably mounted on the tool holder 21 via a pivot 24. The head end 221 of each blade 22 is a free end extending outward relative to the tool holder 21. Each blade 22 has a first state of being inclined upward or downward relative to the horizontal plane, and a second state of being horizontally arranged. In this embodiment, the blades 22 are arranged in pairs facing each other, forming two groups. The blades 22 of the first group are inclined upward in the first state, and the blades 22 of the second group are inclined downward in the first state. Furthermore, each blade 22 is arranged in a clockwise or counterclockwise rotational direction.
[0041] There are four elastic elements 23, each acting on its corresponding blade 22 to ensure that the corresponding blade 22 always tends to rotate to the first state; and each elastic element 23 is arranged to elastically deform when the tool holder 21 rotates at high speed, causing the corresponding blade 22 to rotate to the second state (e.g., ...). Figure 3 The blade 22 in the dashed section is in the second state, and the blade 22 in the solid section is in the first state. Specifically, when the blade 22 is tilted upward relative to the horizontal surface in the first state, the elastic element 23 is a downwardly arched arc-shaped elastic sheet, and the first end 231 of the elastic sheet is sleeved on the outer periphery of the rotating shaft 24 and fixed relative to the rotating shaft 24, while the second end 232 of the elastic sheet is adjacent to or abuts the lower surface of the tool holder 21; when the blade 22 is tilted downward relative to the horizontal surface in the first state, the elastic element 23 is an upwardly arched arc-shaped elastic sheet, and the first end 231 of the elastic sheet is sleeved on the outer periphery of the rotating shaft 24 and fixed relative to the rotating shaft 24, while the second end 232 of the elastic sheet is adjacent to or abuts the upper surface of the tool holder 21.
[0042] The drive mechanism 3 is a motor, and the motor shaft 24 extends upward and is connected to the tool holder 21.
[0043] When the blender is initially in operation, the food is relatively large. The blades rotate at low speed under the drive mechanism 3. The angle of the blades relative to the horizontal plane is large under the action of the elastic element 23, which makes the cutting range of the blades larger and the initial cutting more efficient. After cutting for a certain period of time or after the motor current value is detected to be stable, the motor speed is gradually increased. At this time, the blades rotate under the action of centrifugal force, overcoming the elastic force of the elastic element. The cutting diameter area of each blade becomes larger, further breaking down the food.
[0044] like Figure 2 , 4 As shown in Figures 5 and 6, there are four ribs 4, each extending vertically and arranged at equal intervals along the circumference on the inner side of the chamber 10.
[0045] There are three blocking plates 5, which are horizontally placed at intervals in the vertical direction in the chamber 10. Each blocking plate 5 has a through hole 50 in the center and a notch 51 on the edge of each blocking plate 5 corresponding to the position of each rib 4, so that the rib 4 can be inserted. At the same time, each blocking plate 5 gradually slopes downward from the center to the edge.
[0046] When the blender is working, the rotational force of the liquid generated by the ribs 4 and the blades is perpendicular to each other, which can effectively block the impact of the liquid and block large particles, further increasing the difference between the rotational speed of the liquid and the rotational speed of the blades. The effective cooperation between the ribs 4 and the blades increases the cutting probability. At the same time, since the ribs 4 are made of relatively soft material, they can reduce the impact noise caused by the high-speed rotation of particles.
[0047] Meanwhile, because the liquid will generate a "vortex" phenomenon when it rotates at high speed, that is, the liquid level is high on the outer ring and low in the middle, the suspended baffle can automatically adapt to the liquid level and reduce the "vortex" phenomenon, thereby reducing the risk of "overflow" during the beverage preparation process. The shape of the baffle, which gradually tilts downward from the center to the edge, allows the liquid on the outer ring to reach the baffle earlier and causes the liquid to gather towards the center along the arc, further reducing the "vortex" phenomenon.
[0048] In the specification and claims of this utility model, terms indicating direction, such as "upper," "lower," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
[0049] The term "vertical" is also used in the specification and claims of this utility model, meaning basically along the up and down direction, and is not limited to just the vertical direction, but can also be slightly deviated from the vertical direction.
