Description

Technical Field

[0001] The present invention relates to the technical field of food and medicinal material processing equipment, and in particular to an automatic food and medicinal material grinder driven by magnetic force. Background Art

[0002] Traditional pounding and grinding methods have long been widely used in the primary processing of food and Chinese medicinal materials, especially in home kitchens, Chinese medicine pharmacies, and some small-scale processing scenarios. Common tools include a ceramic or stone bowl combined with a wooden or stone pestle. Users use the pestle to pound food ingredients (such as garlic, chili peppers, Sichuan peppercorns, sesame seeds, and ginger) or medicinal herbs (such as angelica, wolfberries, and dried ginger) to achieve the desired effects, such as crushing, extracting juice, mixing, or pulverizing.

[0003] However, the above-mentioned traditional equipment has obvious limitations and defects, including:

[0004] Traditional pestle and pounding relies entirely on manual labor, requiring users to rely on experience to determine the required force, frequency, and duration. Different operators processing the same raw material can produce significantly different finished products in terms of taste, fineness, and shape, lacking consistency and standardization.

[0005] The pestle generally has a large mass to enhance the impact force, but this also causes users to feel tired after long-term operation, which is not friendly enough, especially for women, the elderly or users with insufficient hand strength.

[0006] Traditional grinding methods have poor processing effects on certain materials with strong fibrous or high hardness, or are even unable to process them, and have obvious adaptability shortcomings.

[0007] The current market lacks intelligent grinding equipment that can set working parameters (such as frequency, stroke, impact force, etc.) according to different raw materials, which cannot meet the growing demand of modern families for convenient, intelligent and standardized processing.

[0008] The user needs to hold the stick continuously to operate and cannot do other things during the process, which makes the use efficiency low. Summary of the Invention

[0009] The purpose of the present invention is to address the defects and shortcomings of the existing technology and provide a food and medicine grinder that frees manpower and automatically completes pounding and grinding; the operating program can be adjusted to adapt to different food ingredients and herbs; the output grinding effect is stable and the consistency is improved; the shock-absorbing spring design buffers impact and extends the service life of the entire machine.

[0010] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: it includes a grinder body 1, a pestle assembly 2, the pestle assembly 2 includes a pestle body 21, a pestle permanent magnet 22 arranged inside the pestle body, a shock-absorbing spring 23 arranged below the pestle permanent magnet, and a pestle cover 24 that closes the upper end of the pestle body 21; a driving device 3 is arranged inside the grinder body 1 for driving the pestle assembly 2 to reciprocate up and down.

[0011] The driving device 3 is a magnetic driving device, which includes: a motor 31 installed inside the grinder body 1; a motor gear 32 connected to the output end of the motor 31; a driving gear 33 meshing with the motor gear 32; a permanent magnet rotating bracket 34 fixed to the driving gear 33; and a main permanent magnet 35 installed in the permanent magnet rotating bracket 34.

[0012] The motor 31 operates under the control of the control system, driving the main body permanent magnet 35 to rotate, and then drives the pestle assembly 2 to achieve linear reciprocating motion in the grinder body through the magnetic repulsion and attraction between the pestle permanent magnet 22 and the pestle permanent magnet.

[0013] A guide structure 4 is provided between the pestle assembly 2 and the grinder body 1 , and the guide structure 4 is used to limit the movement direction of the pestle assembly 2 to axial linear reciprocating.

[0014] A control knob 11 is provided on the bottom side of the grinder body 1 .

[0015] The present invention operates as follows: The grinder comprises a grinder body and a pestle assembly. The pestle assembly comprises the pestle body, a pestle permanent magnet disposed within the pestle body, a shock-absorbing spring positioned below the permanent magnet, and a sealing cover. A magnetic drive mechanism is housed within the grinder body. This mechanism primarily uses a motor to drive a rotating structure, generating a dynamic magnetic field that interacts with the magnet within the pestle assembly.

[0016] The motor starts under the control of the control system, and its output shaft drives the motor gear to rotate. The motor gear meshes with the drive gear, causing the drive gear to rotate synchronously in the opposite direction. The drive gear further drives the permanent magnet rotating bracket mounted on it. The rotating bracket is equipped with a main permanent magnet. As the main permanent magnet rotates, its polarity (north and south poles) continuously changes relative position.

[0017] Since the pestle assembly is also provided with a pestle permanent magnet, when the main body permanent magnet rotates, its polarity and the pestle permanent magnet will periodically form a magnetic force of "like repels like" and "opposites attract each other". This magnetic force directly applies an alternating upward and downward push and pull force to the pestle assembly, causing the pestle assembly to produce linear reciprocating motion in the vertical direction within the grinder body. In order to ensure that the pestle assembly only moves in the vertical direction, a guide structure is provided between the grinder body and the pestle assembly to limit its deflection or rotation. Ultimately, through the dynamic control of the electromagnetic force, the pestle is regularly driven, thereby achieving high-frequency automatic pounding and grinding of food or medicinal materials in the bowl.

[0018] After adopting the above technical solution, the beneficial effects of the present invention are as follows: it realizes motion drive through the magnetic field effect between permanent magnets, without the need for direct mechanical connection, avoiding mechanical friction, loss and noise problems, and significantly improving the life and stability of the whole machine. This device is started with one button through the automatic control system, and can continuously complete the hammering and grinding tasks, greatly reducing the labor intensity of the user. The present invention adopts magnetic drive to achieve a stable and controllable motion rhythm, and cooperates with a shock-absorbing spring buffer structure to achieve repeated hammering with uniform force and controllable frequency, which is suitable for a variety of food and medicinal materials with different hardness. It adopts a transmission mode of motor-gear-rotating bracket-magnet, and the mechanical structure is highly integrated. At the same time, the guide structure is used to ensure the precise movement direction of the hammer, making the operation process efficient and stable.

[0019] The only control knob on the periphery allows users to adjust the operating mode or force to suit the grinding requirements of different ingredients, improving the user experience while ensuring both aesthetics and operational effectiveness. The low-noise design of this invention makes it suitable for home use: due to the use of indirect magnetic drive and a shock-absorbing structure, the overall operating process is quiet, making it suitable for kitchens, pharmacies, baby food stores, and other environments that require a quiet environment.

DETAILED DESCRIPTION

[0027] Example 1

[0028] See Figure 1-3 As shown, the technical solution adopted in this specific embodiment is as follows: it includes a grinder body 1 and a pestle assembly 2. The pestle assembly 2 includes a pestle body 21, a pestle permanent magnet 22 disposed within the pestle body, a shock-absorbing spring 23 disposed below the pestle permanent magnet, and a pestle cover 24 that seals the upper end of the pestle body 21. A magnetic drive device 3 is disposed within the grinder body 1 for driving the pestle assembly 2 to reciprocate up and down. The magnetic drive device 3 includes: a motor 31 mounted within the grinder body 1; a motor gear 32 connected to the output end of the motor 31; a drive gear 33 meshing with the motor gear 32; a permanent magnet rotating bracket 34 fixed to the drive gear 33; and a main body permanent magnet 35 mounted within the permanent magnet rotating bracket 34. The motor 31 operates under the control of a control system, driving the main body permanent magnet 35 to rotate. This, in turn, drives the pestle assembly 2 to achieve linear reciprocating motion within the grinder body through the magnetic repulsion and attraction between the motor 31 and the pestle permanent magnet 22. A guide structure 4 is provided between the pestle assembly 2 and the grinder body 1. The guide structure 4 is used to limit the movement direction of the pestle assembly 2 to an axial linear reciprocating direction. A control knob 11 is provided on the bottom side of the grinder body 1.

[0029] This embodiment utilizes a magnetic drive with a stable and controllable rhythm, coupled with a shock-absorbing spring structure, to achieve repeated beatings with uniform force and controllable frequency, making it suitable for a variety of food and medicinal materials of varying hardness. It utilizes a motor-gear-rotating bracket-magnet transmission mechanism, resulting in a highly integrated mechanical structure. A guide structure ensures precise movement of the pestle, ensuring efficient and stable operation.

[0030] Example 2

[0031] See Figure 1 、 4As shown in Figure 5, the difference between this embodiment and embodiment 1 is that the driving device 3 is an electromagnetic direct drive mechanism, which includes an electromagnetic coil 51, and a buffer permanent magnet 52 is provided underneath; the electromagnetic coil 51 changes the direction of the magnetic pole by periodically switching the current direction through the control system PCBA, and uses the magnetic field attraction and repulsion effect to drive the beating stick assembly 22 to produce reciprocating motion.

[0032] The control system switches the direction of the current in the electromagnet or electromagnetic coil according to the program, periodically changes its polarity, and forms periodic attraction and repulsion with the permanent magnet in the pestle assembly, thereby driving the pestle assembly to move up and down rapidly in the main body to achieve automatic grinding.

[0033] Other components and connection relationships are the same as those in Example 1.

[0034] What embodiment 1 adopts is rotating permanent magnet drive structure, its core is to drive the main body permanent magnet on the rotating bracket to rotate continuously by motor, utilize the periodic change of magnetic pole direction, produce repulsion and attraction with the permanent magnet inside the club, thereby driving the club to move up and down. This method relies on mechanical transmission, and the structure includes motor, gear and rotating parts, has the advantages of strong stability and large impact force, and is suitable for processing food or medicinal materials with larger hardness and coarse particles. However, due to the presence of multiple transmission parts, the structure is relatively complex, and the cost and volume are slightly high.

[0035] In contrast, Example 2 uses an electromagnet drive method, which periodically changes the direction of the current in the electromagnet or electromagnetic coil through a control system, thereby changing the magnetic polarity and forming an alternating magnetic force with the permanent magnet of the pestle to achieve linear reciprocating motion. In contrast, this method does not rely on a rotating mechanism, has a simpler structure, and a faster control response speed. It is particularly suitable for scenarios that require high-speed, lightweight operation, such as grinding softer or higher-frequency raw materials. At the same time, due to the reduction of mechanical friction components, its noise and energy consumption are also relatively low.

[0036] In summary, the two driving modes have their own advantages and disadvantages. Example 1 is more suitable for high-intensity hammering needs and has a wide range of applications; Example 2 highlights intelligence and lightness, and is suitable for application scenarios such as home kitchens and small grinding. Users can choose according to actual needs.

[0037] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
