Description

Technical Field

[0001] This utility model relates to the technical field of high-speed blenders, and in particular to a pulverizing device used in high-speed blenders. Background Technology

[0002] The pulverizing device used in a high-speed blender employs a high-speed electric motor to drive stainless steel blades, cutting and blending ingredients within the blender. This process pulverizes the ingredients to a fine degree, reducing the cell walls to a fine texture and fully releasing nutrients such as vitamins, minerals, phytochemicals, and proteins from the cells. A high-speed blender combines the functions of a juicer, soy milk maker, ice cream maker, food processor, and grinder, offering multiple uses in one machine. After a period of use, the blades may become dull and lose their sharpness, requiring replacement. Alternatively, the blade assembly may need to be disassembled for thorough cleaning of the bottom of the blender and the heating plate.

[0003] Currently, the existing technology disclosed in Chinese Utility Model Patent No. ZL202421427891.4 is a structure for a quick-change blade blender for soy milk. This structure includes a shell and a driver. A bottom cover is installed inside the shell. A heating plate is connected to the upper part of the bottom cover via a heating plate fixing ring. A cup body is connected to the upper part of the heating plate. A sealing ring is installed between the cup body and the heating plate fixing ring. A blade shaft is rotatably installed in the middle of the heating plate and the bottom cover. A blade head is detachably installed at the upper end of the blade shaft. The driver is located below the shell, and the input end of the blade shaft is connected to the output end of the driver. The cutting head includes a handle, a retaining sleeve, a blade, and multiple balls. The blade is riveted to the handle. A groove is formed on the lower outer wall of the handle. The retaining sleeve is installed below the blade and fits into the lower part of the handle. A retaining spring is engaged in the groove to limit the position of the retaining sleeve. The retaining sleeve has ball holes for installing balls. The lower part of the handle has ball grooves with a gradually changing depth to cooperate with the balls. This allows for multiple cutting heads to be used on one machine when changing cutting heads. When the cutting head needs to be removed, the handle is rotated in the opposite direction. The highest point of the ball groove moves away from the ball groove. At this time, pulling the handle will cause the balls to retract into the retaining sleeve without support, and the cutting head is removed. When debris accumulates in the ball holes or ball grooves, the balls cannot pop out of the ball holes or cannot disengage from the ball grooves, causing the quick cutting head replacement function to fail. Furthermore, this structure is complex. Utility Model Content

[0004] The purpose of this invention is to provide a pulverizing device and a high-speed blender with easily detachable blades to solve the problems mentioned in the background art. The blades on this pulverizing device are easy to disassemble, and its structure is particularly simple, making it more suitable for use in high-speed blenders.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A crushing device with easily disassembled blades includes a blade shaft, blades, a sleeve seat, and an elastic limiting member. The blades are fixedly connected to the sleeve seat wall, and the sleeve seat has two symmetrically arranged slots at its lower opening. The lower shaft of the blade shaft has two symmetrically arranged cross pins, and the top shaft of the blade shaft has an annular groove. The elastic limiting member is fitted into the annular groove and is securely connected to the top of the blade shaft.

[0007] The sleeve seat, carrying the cutting tool, is fitted onto the cutter shaft from top to bottom. The slot engages with the transverse pin to restrict the radial movement of the sleeve seat. The top shaft of the cutter shaft, carrying an elastic limiting member, extends from the upper shaft hole of the sleeve seat. The elastic limiting member is interference-fitted with the upper shaft hole and presses against the top surface of the sleeve seat to restrict the axial movement of the sleeve seat. The cutting tool is fixedly connected to the cutter shaft.

[0008] Furthermore, the lower opening of the slot is provided with a notch, and the horizontal pin is cylindrical. The notch guides the slot on the sleeve seat to smoothly slide onto the horizontal pin.

[0009] Furthermore, in order to facilitate the removal of the cutting tool from the cutting shaft for tool replacement, a handle is provided on the upper part of the sleeve seat above the cutting tool. The handle is formed by the inward indentation of the upper part of the sleeve seat.

[0010] Furthermore, in order to facilitate the passage of the elastic limiting member through the shaft hole in the sleeve seat, the inner diameter of the lower shaft hole of the sleeve seat is slightly larger than the diameter of the elastic limiting member.

[0011] The elastic limiting component is an O-ring silicone ring; a countersunk hole is provided at the opening of the upper shaft hole on the top surface of the sleeve seat, and the silicone ring is partially embedded in the countersunk hole.

[0012] Another technical solution of this utility model: A high-speed blender includes a blending cup and a motor. The motor is located at the bottom of the blending cup, and the rotating shaft of the motor passes upward through the bottom plate of the blending cup and is screwed and fixedly connected to the pulverizing device, which is installed inside the blending cup. When the blades become dull after a period of use, the user can pinch the handle on the sleeve seat and pull it upward. The elastic limiting member is deformed and reduced by external force, and the sleeve seat, along with the blades, separates from the blade shaft. Then, a brand new, sharp blade of the same specification can be installed back onto the blade shaft.

[0013] This utility model provides a crushing device and a high-speed blender with easy-to-disassemble blades. Because the blades on the crushing device are restricted to radial movement by a slot on the sleeve seat and a cross pin, and the axial movement of the blades is restricted by an O-ring silicone ring and a countersunk hole on the top surface of the sleeve seat, the blades are very easy to disassemble and replace.

[0024] The sleeve seat 3, carrying the cutter 2, is fitted onto the cutter shaft 1 from top to bottom. The slot 7 engages with the cross pin 5 to restrict the radial movement of the sleeve seat 3. The top shaft of the cutter shaft 1, carrying the elastic limiting member 4, passes through and extends from the upper shaft hole of the sleeve seat 3 with an interference fit. The elastic limiting member 4 presses against the top surface of the sleeve seat 3 to restrict the axial movement of the sleeve seat 3. The cutter 2 is fixedly connected to the cutter shaft 1.

[0025] Furthermore, the horizontal pin 6 is cylindrical, and the lower opening of the slot 5 is provided with a notch 51, which guides the slot 5 on the sleeve seat to smoothly slide onto the horizontal pin 6.

[0026] Furthermore, in order to facilitate the removal of the cutting tool from the cutting shaft for tool replacement, a handle 31 is provided on the upper part of the sleeve seat 3 located above the cutting tool 2. The handle 31 is formed by the inward indentation of the upper part of the sleeve seat 3.

[0027] Furthermore, in order to facilitate the smooth passage of the elastic limiting member 4 through the shaft hole in the sleeve seat 3, the inner diameter of the lower shaft hole in the sleeve seat 3 is slightly larger than the diameter of the elastic limiting member 4.

[0028] The elastic limiting member 4 is an O-ring silicone ring; a countersunk hole 32 is provided at the upper shaft hole opening on the top surface of the sleeve seat 3, and part of the O-ring silicone ring is embedded in the countersunk hole 32.

[0029] like Figure 5 As shown, a high-speed blender includes a blending cup 81 and a motor 82. The motor 82 is located at the bottom of the blending cup 81. The rotating shaft of the motor 82 passes upward through the bottom plate of the blending cup 81 and is screwed and fixedly connected to the crushing device. The crushing device is installed inside the blending cup 81. The motor 82 drives the crushing device to rotate at high speed to make food.

[0030] The principle of this invention is as follows: When the blades on the blender become dull after a period of use, the user can pinch the handle 31 on the sleeve seat and pull it upwards. The elastic limiting member 4 is deformed and reduced by external force, and the sleeve seat, along with the blade 2, separates from the blade shaft 1. Then, a brand new, sharp blade of the same specification is installed back onto the blade shaft, which realizes quick disassembly of the blade, and the connection structure between the blade and the blade shaft is also very simple.

[0031] Although the embodiments of this utility model have shown the technical solutions, those skilled in the art can understand that the technical solutions proposed by replacing, modifying or altering these embodiments in combination with conventional technology without departing from the principles and structure of this utility model are substantially the same as those of this utility model.
