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 typically have their blades fixed at the bottom of the machine. When blending food, the small gap between the blades and the bottom makes it difficult to clean away residual food fibers and impurities, easily leading to mold growth on the bottom and affecting the user experience. Secondly, after blending, the finished product tends to remain at the bottom, making it inconvenient to use. Furthermore, most existing high-speed blenders use unidirectional rotating blades; as the rotation speed increases, the noise level also increases, becoming a concern for users. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-speed blender that is easy to clean up food residue at the bottom, 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 clockwise or counterclockwise around its central vertical axis under the drive of the drive mechanism.

[0010] At least two blades are arranged on the blade holder around the axis, and the first end of each blade is mounted on the blade holder in a manner that allows it to rotate about its corresponding vertically extending axis. The second end of each blade is a free end. When the blade holder rotates clockwise, the second end of each blade rotates outward in a posture away from the blade holder and is located on the periphery of the blade holder, and the windward side of each blade has a cutting edge. When the blade holder rotates counterclockwise, the second end of each blade rotates inward and retracts, at which time the cutting edge of each blade faces inward.

[0011] By designing the pulverizing blade with a blade holder and at least two blades, with the first end of each blade mounted on the blade holder in a manner that allows it to rotate around its corresponding vertically extending axis, and the second end of each blade being a free end, when the blade holder rotates clockwise, the second end of each blade can rotate outward relative to the blade holder and be located on the periphery of the blade holder. The windward side of each blade has a cutting edge, thereby achieving effective cutting and pulverizing of food. Conversely, when the blade holder rotates counterclockwise, each blade rotates inward and retracts, with the cutting edge facing inward. After the blade holder stops rotating, it is convenient to clean the food residue at the bottom of the chamber, avoiding hand injuries from the blade edges during cleaning, thus solving the problem of difficult cleaning in existing high-speed blenders. At the same time, the extension of each blade when rotating clockwise and retraction when rotating counterclockwise can effectively reduce noise and improve the problem of excessive noise from existing unidirectional rotating blades.

[0012] Preferably, the tool holder includes:

[0013] The active seat is connected to the output end of the drive mechanism, and the active seat is provided with the aforementioned rotating shafts corresponding to the positions of each blade;

[0014] The driven ring is located on the periphery of the driving seat, and the driven ring has upwardly extending limit posts corresponding to the positions of each blade;

[0015] Each blade has a strip-shaped hole extending along its length in the middle, which is used to constrain the corresponding driven ring's limiting post.

[0016] When the drive seat rotates forward, it drives the blade and driven ring to rotate forward. The strip hole on the blade moves relative to the limit post on the driven ring, thereby driving the blade to rotate outward and extend. Conversely, when the drive seat rotates in reverse, it drives the blade and driven ring to rotate in reverse. The strip hole on the blade moves in the opposite direction relative to the limit post on the driven ring, thereby driving the blade to retract.

[0017] Preferably, the strip-shaped hole has:

[0018] The first end, relatively close to the first end of the blade;

[0019] The second end, relatively close to the second end of the blade;

[0020] When the tool holder rotates forward, the strip-shaped holes on each blade extend radially along the corresponding driven ring, and the limiting post is located at the first end of the corresponding strip-shaped hole; when the tool holder rotates in reverse, the extending direction of the strip-shaped holes on each blade is arranged at an angle to the radial direction of the corresponding driven ring, and the limiting post is located at the second end of the corresponding strip-shaped hole.

[0021] Furthermore, the active seat includes:

[0022] Active loop, where the axis is the axis mentioned above;

[0023] Connecting arms extend radially outward from the outer circumferential surface of the automatic drive ring. The number of connecting arms matches the number of blades, and each connecting arm is arranged at circumferential intervals along the drive ring. The outer end of each connecting arm is provided with the aforementioned rotating shaft.

[0024] Furthermore, when the tool holder reverses, the extension direction of the strip holes on each blade is perpendicular to the extension direction of the connecting arm where the blade is located.

[0025] In the above scheme, in order to limit the position of each blade when it rotates forward, preferably, the active seat is provided with a limiting protrusion corresponding to the position of each rotating shaft. When the blade holder rotates forward, the limiting protrusion is located on the leeward side of the corresponding blade and contacts the first end of the corresponding blade.

[0026] In the above embodiments, to improve the cell wall breaking efficiency, preferably, the chamber has a bottom wall and an annular sidewall extending upward from the periphery of the bottom wall. The annular sidewall is provided with ribs that extend upward at an incline, with the incline direction opposite to the forward rotation direction of the blade holder. The rib design slows down the flow velocity of the liquid within the chamber and changes the flow direction of the liquid, thereby improving the cell wall breaking efficiency of the pulverizer.

[0027] Preferably, the angle between the rib and the horizontal plane is 30 to 60°.

[0028] Preferably, there are at least two ribs arranged circumferentially along the annular sidewall.

[0029] Preferably, the shredder is located below the rib.

[0030] Compared with existing technologies, the advantages of this invention are as follows: By designing the pulverizing blade with a blade holder and at least two blades, the first end of each blade is mounted on the blade holder in a manner that allows it to rotate around its corresponding vertically extending axis. The second end of each blade is a free end. When the blade holder rotates clockwise, the second end of each blade can rotate outward relative to the blade holder and be located on the periphery of the blade holder. The windward side of each blade has a cutting edge, thereby achieving effective cutting and pulverizing of food. Conversely, when the blade holder rotates counterclockwise, each blade rotates inward and retracts, with the cutting edge facing inward. After the blade holder stops rotating, it is convenient to clean the food residue at the bottom of the chamber, avoiding hand injuries from the blade edges during cleaning, thus solving the problem of difficult cleaning in existing blenders. At the same time, the extension of each blade during clockwise rotation and retraction during counterclockwise rotation can effectively reduce noise and improve the problem of excessive noise from existing unidirectional rotating blades.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] Example 1:

[0039] like Figures 1-5 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, and a drive mechanism.

[0040] The housing 1 has a chamber 10 with a feed inlet at the top, and a cover 14 for opening and closing the feed inlet. The chamber 10 has a bottom wall 11 and an annular sidewall 12 extending upwards from the periphery of the bottom wall 11. Ribs 13 protrude from the annular sidewall 12 and gradually slope upwards along it, with the slope direction opposite to the forward rotation direction of the cutter holder 20. In this embodiment, there are three ribs 13, spaced apart circumferentially along the annular sidewall 12. The angle between each rib 13 and the horizontal plane is 30° to 60° (the angle can be any value between 30° and 60°, such as 30°, 40°, 50°, 60°, etc.). The angle between each rib 13 and the horizontal plane remains constant from bottom to top. Simultaneously, the bottom of the annular sidewall 12 has an outlet that can be opened or closed. When the outlet is open, the slurry after cell disruption can be discharged through the outlet. The opening and closing mechanism of the outlet is the same as in the prior art and will not be described in detail here.

[0041] The aforementioned crushing blade 2 is located inside the chamber 10, below the rib 13, and can work under the drive of the drive mechanism (which is an existing motor) to crush the food ingredients that enter from the feed inlet. Specifically, the crushing blade 2 includes a blade holder 20 and four blades 21.

[0042] The tool holder 20 includes a driving seat 22 and a driven ring 23. The driving seat 22 has a driving ring 221 and connecting arms 222 extending radially outward from the outer circumference of the driving ring 221. There are four connecting arms 222, which are arranged at intervals along the circumference of the driving ring 221. Each connecting arm 222 has an upwardly extending rotating shaft 24 at its outer end. The driving ring 221 is connected to the motor shaft and can rotate clockwise or counterclockwise around its central vertically extending axis 200 under the drive of the motor shaft. The driven ring 23 is located on the periphery of the driving seat 22, and the driven ring 23 has upwardly extending limiting posts 231 corresponding to the positions of each connecting arm 222.

[0043] Four blades 21 are arranged on the tool holder 20 around axis 200, and the first end 211 of each blade 21 is sleeved on the outer circumference of its corresponding rotating shaft 24 and can rotate around the rotating shaft 24. The second end 212 of each blade 21 is a free end. Each blade 21 has a strip-shaped hole 214 extending along the length direction of the blade 21 in the middle, so that the limiting post 231 on the corresponding driven ring 23 can be constrained therein (through the cooperation of the limiting post 231 and the strip-shaped hole 214, the driven ring 23 can be constrained with each blade 21 and rotate clockwise or counterclockwise with each blade). The strip-shaped hole 214 has a first end 214a and a second end 214b, with the first end 214a relatively close to the first end 211 of the blade 21 and the second end 214b relatively close to the second end 212 of the blade 21.

[0044] like Figure 2 , 3As shown, when the tool holder 20 rotates forward, the second end 212 of each blade 21 rotates outward in a posture away from the tool holder 20 and is located on the periphery of the tool holder 20. At this time, the strip hole 214 on each blade 21 extends radially along the corresponding driven ring 23, the limiting post 231 is located at the first end 214a of the corresponding strip hole 214, and each blade 21 has a cutting edge 213 on the windward side.

[0045] In order to limit the position of the blade when rotating forward, each connecting arm 222 is provided with a limiting protrusion 25 on its outer end. When the blade holder 20 rotates forward, the limiting protrusion 25 is located on the leeward side of the corresponding blade 21 and contacts the first end 211 of the corresponding blade 21.

[0046] like Figure 4 As shown, when the tool holder 20 reverses, the second end 212 of each blade 21 rotates inward and retracts. At this time, the cutting edge 213 of each blade 21 faces inward, and the extension direction of the strip hole 214 on each blade 21 is perpendicular to the extension direction of the connecting arm 222 where the blade 21 is located. The limiting post 231 is located at the second end 214b of the corresponding strip hole 214. During reverse rotation, the blade is limited by the cooperation between the strip hole 214 and the limiting post 231.

[0047] In summary, this embodiment, by incorporating an extendable and retractable rotating blade, allows the blade to extend for cell wall breaking during normal operation and retract during cleaning, preventing hand injuries during cleaning and increasing the distance between the blade and the annular sidewall, facilitating the removal of residual food fibers and other impurities. Simultaneously, the inclined ribs 13 slow down the liquid flow rate and change its direction, improving cell wall breaking efficiency. Furthermore, the blade's extension during forward rotation and retraction during reverse rotation effectively reduces noise.

[0048] Example 2:

[0049] like Figure 6 As shown, this is a preferred embodiment of the blender of the present invention. This embodiment is basically the same as the first embodiment, except that the inclination angle of each rib 13 is different in this embodiment, and the angle between a single rib 13 and the horizontal plane gradually decreases from bottom to top.

[0050] 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.

[0051] 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.

[0052] The term "radial" is also used in the specification and claims of this utility model, meaning basically along the inside and outside direction, and is not limited to the radial direction that passes through the center of the circle, but can also be slightly deviated from the radial direction.
