Description

Technical Field

[0001] This utility model relates to the field of bean grinding technology, and in particular to an adjustable grinder. Background Technology

[0002] An adjustable grinder is a device that allows for precise adjustment of the particle size of powder according to needs. Its core function is to control the particle size of the ground beans by adjusting the spacing of the grinding components. It is usually equipped with an adjustment mechanism, which changes the spacing of the blades by rotating the adjustment components: the smaller the spacing, the finer the powder; the larger the spacing, the coarser the powder. Different powder sizes are suitable for different brewing methods. Therefore, adjustable grinders can meet diverse brewing needs and help users adjust the powder size according to their preferences or brewing equipment, thereby optimizing the extraction effect and taste.

[0003] The distance between a pair of relatively rotating cutter discs (or grinding cores) in the grinding chamber is changed by adjusting mechanisms such as knobs and dials, using thread or gear transmission. After the beans enter from the feed inlet, they are sheared, crushed and pulverized between the rotating cutter discs. The smaller the distance, the finer the powder particles, and the larger the distance, the coarser the powder particles. Finally, the ground powder falls into the powder hopper below through the gap between the cutter discs to complete the collection, thereby achieving precise control over the fineness of the powder.

[0004] In existing technologies, some adjustable grinders typically rely on rigid mechanical structures to fix the blade spacing. When the blades wear out after long-term use, or are impacted by beans during grinding, or as the usage time increases, the blades inevitably suffer wear and tear, and the blade spacing is prone to slight deviation, resulting in a decrease in adjustment accuracy. Therefore, an adjustable grinder is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable grinder, which aims to improve the problem that the adjustment accuracy of some adjustable grinders inevitably decreases as the cutter disc wears down with increasing use time.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable grinder includes a housing, an inner feed port fixedly connected to the inside of the housing, an adjusting mechanism fixedly connected to the top of the feed port, a sealing cover fixedly connected to the top of the adjusting mechanism, a connecting ring fixedly connected to the outside of the sealing cover, a storage cup threadedly connected to the top of the connecting ring, a control mechanism fixedly connected to the front side of the adjusting mechanism, and a flow guide fixedly connected to the rear side of the adjusting mechanism.

[0008] The adjustment mechanism includes a bracket, a motor is fixedly connected to the top of the bracket, a battery is fixedly connected to the top of the motor, a grinding head is slidably connected to the bottom of the bracket, and an adjustment component is fixedly connected to the drive end of the motor.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a rotating shaft, a pre-tightening spring sleeved on the outside of the rotating shaft, a movable grinding head slidably connected to the outside of the rotating shaft, a push ring slidably connected to the bottom of the movable grinding head, a rotating shaft slidably connected to the bottom of the push ring, and a rotating block fixedly connected to the outside of the rotating shaft.

[0011] As a further description of the above technical solution:

[0012] The bottom of the bracket is fixedly connected to the top of the feed port, and the top of the rotating shaft is fixedly connected to the drive end of the motor.

[0013] As a further description of the above technical solution:

[0014] The other end of the preload spring is fixedly connected to the top of the moving grinding head, and the internal thread of the rotating shaft is connected to the outside of the rotating shaft;

[0015] As a further description of the above technical solution:

[0016] The control mechanism includes a vertical plate, a connecting frame is fixedly connected to the front side of the vertical plate, and a limit component is fixedly connected to the front side of the connecting frame;

[0017] As a further description of the above technical solution:

[0018] The limiting component includes a button, a slide rod is slidably connected inside the button, two spring rods are slidably connected inside the connecting frame, a slip ring is slidably connected outside the slide rod, and two limiting blocks are slidably connected inside the connecting frame;

[0019] As a further description of the above technical solution:

[0020] The far side of each limiting block is fixedly connected to the near side of each of the two spring rods, and the outside of the slip ring is slidably connected to the inside of the connecting frame;

[0021] As a further description of the above technical solution:

[0022] The rear side of the vertical plate is fixedly connected to the front side of the bracket, and the rear side of the button is slidably connected to the front side of the connecting frame.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by rotating the rotating block, the rotating shaft moves, thereby causing the rotating shaft to rotate along the bottom of the rotating shaft, which in turn drives the push ring to move, causing the push ring to drive the moving grinding head to move, thus reducing or increasing the distance between the moving grinding head and the fixed grinding head. The pre-tightening spring provides limit and buffer for the moving grinding head, thereby realizing convenient adjustment of the distance between the fixed grinding head and the moving grinding head. This makes the structure for adjusting the grinding coarseness simple and convenient, reduces the occupied area, and makes the later maintenance of the entire equipment simpler and more convenient.

[0025] 2. In this utility model, by sliding the slide rod to the right, the protrusion at one end of the slide rod presses the two limiting blocks to a distance, causing the slide rod to fit into the gap between the two limiting blocks. After the slide rod fits into the gap between the two limiting blocks, the spring outside the spring rod will press the limiting blocks back to their original positions, locking the slide rod in place. When the grinder needs to be used again, slide the slide rod to the right again to let the slip ring pass through the gap formed by the two limiting blocks, and then pull the slide rod to the left to let the slide rod slide out of the button, releasing the slide rod from the button and achieving the limiting of the button, preventing accidental activation of the grinder.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 2 The present invention provides an embodiment of an adjustable grinder, comprising a housing 1, which serves as an overall support frame, providing a mounting base for internal components and providing protection. A feed inlet 2 is fixedly connected inside the housing, used to guide the ground powder to a lower collection area. An adjustment mechanism 3 is fixedly connected to the top of the feed inlet 2, which is a component for adjusting the grinding fineness. A sealing cover 7 is fixedly connected to the top of the adjustment mechanism 3, which is used to close the top opening of the adjustment mechanism 3 to prevent beans from leaking out or foreign objects from entering. A connecting ring 4 is fixedly connected to the outside of the sealing cover 7, and the connecting ring 4 has an internal thread on its inner side, which enables a detachable connection with the storage cup 5 through thread engagement.

[0034] The top of the connecting ring 4 is threaded with a storage cup 5, which is used to store the beans to be ground. Its bottom opening is connected to the sealing cap 7, so that the beans can fall naturally into the adjusting mechanism 3. The front side of the adjusting mechanism 3 is fixedly connected with a control mechanism 6, which integrates a switch. By controlling the start and stop of the motor 32, the grinding process can be controlled. The rear side of the adjusting mechanism 3 is fixedly connected with a guide shroud 8, which is used to guide the small amount of dust generated during grinding to a specific area to reduce dust accumulation inside the outer shell 1.

[0035] The adjustment mechanism 3 includes a bracket 31 for fixing the motor 32, battery 34 and fixed grinding head 33 to ensure the stability of each component. The top of the bracket 31 is fixedly connected to the motor 32, which serves as a power source to drive the adjustment component 35. The top of the motor 32 is fixedly connected to the battery 34, which provides power to the motor 32 and the control mechanism 6. The bottom of the bracket 31 is slidably connected to the fixed grinding head 33, which is fixed in position and has annular grinding teeth on its inner side, which cooperate with the moving grinding head 353 to form a grinding cavity. The drive end of the motor 32 is fixedly connected to the adjustment component 35, which adjusts the position of the moving grinding head 353 through mechanical transmission, thereby changing the grinding coarseness.

[0036] The adjustment component 35 includes a rotating shaft 351. One end of the rotating shaft 351 is fixedly connected to the drive end of the motor 32, and the other end passes through the moving grinding head 353. When the motor 32 is running, it drives the rotating shaft 351 to rotate at high speed, and then drives the moving grinding head 353 to rotate synchronously through the rotating shaft 351. A pre-tensioning spring 352 is sleeved on the outside of the rotating shaft 351. One end of the pre-tensioning spring 352 abuts against the housing of the motor 32, and the other end abuts against the top of the moving grinding head 353. The moving grinding head 353 is pre-pressed towards the fixed grinding head 33 by continuous elastic force, and then the wear gap between the moving and fixed grinding heads 33 is compensated by the elastic force to achieve the effect of maintaining grinding accuracy for a long time. The moving grinding head 353 is slidably connected to the outside of the rotating shaft 351. The outside of the moving grinding head 353 is provided with grinding teeth that are adapted to the fixed grinding head 33. It can slide along the rotating shaft 351. Through relative rotation and spacing changes with the fixed grinding head 33, the grinding effect is achieved.

[0037] A push ring 354 is slidably connected to the bottom of the moving grinding head 353. The inner side of the push ring 354 is threadedly connected to the rotating shaft 355, and the outer side is in contact with the bottom of the moving grinding head 353. When the rotating shaft 355 rotates, it drives the push ring 354 to move axially, and then pushes the moving grinding head 353 to slide along the rotating shaft 351 through the push ring 354, thereby changing the distance between the moving and fixed grinding heads 33. The bottom of the push ring 354 is slidably connected to the rotating shaft 355. The outer side of the rotating shaft 355 is provided with an external thread. When the rotating block 356 drives the rotating shaft 355 to rotate, the rotational motion is converted into the axial linear motion of the push ring 354 through the threaded engagement, thereby achieving the effect of moving the push ring 354. The rotating block 356 is fixedly connected to the outside of the rotating shaft 355 for manual rotation by the user. When the rotating block 356 rotates, it drives the rotating shaft 355 to rotate synchronously, and then adjusts the distance between the moving and fixed grinding heads 33 through the transmission chain to achieve the effect of controlling the fineness of the powder.

[0038] Reference Figure 3 and Figure 4 The control mechanism 6 includes a vertical plate 61, which is fixedly connected to the bracket 31 of the adjustment mechanism 3 to provide stable support for the connecting frame 62. The connecting frame 62 is fixedly connected to the front side of the vertical plate 61. The connecting frame 62 is a frame structure with an internal sliding rail for accommodating and guiding the movement of each component of the limiting component 63. At the same time, it connects the limiting component 63 to the vertical plate 61. The limiting component 63 is fixedly connected to the front side of the connecting frame 62.

[0039] The limiting component 63 includes a button 631, which protrudes from the outer casing 1 for user operation by pressing. A slide rod 632 is slidably connected inside the button 631. One end of the slide rod 632 engages with the button 631, and the other end extends into the connecting frame 62. Two spring rods 635 are slidably connected inside the connecting frame 62. Each spring rod 635 consists of a rod body and a sleeved spring. One end is fixed to the inner wall of the connecting frame 62, and the other end is connected to the limiting block 634. In its natural state, the spring force pushes the limiting block 634 to maintain it in the limited position. When the limiting block 634 is pushed, the spring rod 635 retracts and stores force, ensuring the continued operation of the limiting function through elastic reset. Effectively, a slip ring 633 is slidably connected to the outside of the slide rod 632, and the outer side abuts against two limit blocks 634. When the slide rod 632 slides downward, the movement of the slip ring 633 pushes the two limit blocks 634 to move synchronously. Two limit blocks 634 are slidably connected inside the connecting frame 62. The inner side of the limit block 634 is provided with a protrusion that matches the outer groove of the rotating block 356. In its natural state, it is engaged in the groove of the rotating block 356 under the action of the spring rod 635. When pushed by the slip ring 633, the limit block 634 slides to both sides along the track of the connecting frame 62. By engaging and disengaging the limit blocks 634, the slide rod 632 is controlled to prevent accidental activation of the grinding machine.

[0040] Reference Figure 1 , Figure 3 The bottom of the bracket 31 is fixedly connected to the top of the feed port 2. The bracket 31 provides reliable support for components such as the motor 32 and the fixed grinding head 33. The overall structure prevents component displacement caused by vibration during the grinding process. The top of the rotating shaft 351 is fixedly connected to the drive end of the motor 32. When the motor 32 is running, the torque of the drive end directly drives the rotating shaft 351 to rotate. Then, the rotation of the rotating shaft 351 transmits power to the moving grinding head 353, so as to drive the moving grinding head 353 to rotate relative to the fixed grinding head 33 to achieve the grinding effect.

[0041] The other end of the preload spring 352 is fixedly connected to the top of the moving grinding head 353. One end of the preload spring 352 abuts against the housing of the motor 32, and the other end is fixed to the moving grinding head 353. The elastic deformation of the spring generates a continuous downward preload force, which drives the moving grinding head 353 to always be in contact with the fixed grinding head 33. The elastic force compensates for the wear gap caused by long-term use. The internal thread of the rotating shaft 355 is connected to the outside of the rotating shaft 351. When the rotating block 356 drives the rotating shaft 355 to rotate, the rotating shaft 355 moves axially along the rotating shaft 351 through the thread transmission. Then, the axial displacement of the rotating shaft 355 pushes the push ring 354 to achieve the effect of adjusting the distance between the moving grinding head 353 and the fixed grinding head 33.

[0042] The far side of the limiting block 634 is fixedly connected to the near side of the two spring rods 635. The spring rods 635 directly transmit their elastic force to the limiting block 634 through the fixed connection with the limiting block 634. The external sliding connection of the slip ring 633 is slidably connected to the inside of the connecting frame 62. The connecting frame 62 provides a radial sliding track for the slip ring 633. When the sliding rod 632 pushes the slip ring 633, the radial movement of the slip ring 633 accurately pushes the limiting blocks 634 on both sides, thereby achieving the effect of controlling the opening and closing of the limiting blocks 634.

[0043] The rear side of the vertical plate 61 is fixedly connected to the front side of the bracket 31. This fixed connection integrates the control mechanism 6 and the core bracket 31 of the adjustment mechanism 3, allowing the control mechanism 6 to be positioned synchronously with the adjustment mechanism 3. The rear side of the button 631 is slidably connected to the front side of the connecting frame 62. The connecting frame 62 provides axial sliding guidance for the button 631. When the user presses the button 631, the button 631 slides stably backward along the front track of the connecting frame 62.

[0044] Working principle: When grinding beans is required, first open the sealing cover 7 and pour the beans into it. The beans fall into the fixed grinding head 33 through the guide shroud 8. When adjusting the grinding time, the rotating block 356 can be manually rotated. The rotating block 356 rotates, driving the rotating shaft 355 to move. This causes the rotating shaft 355 to rotate along the bottom of the rotating shaft 351, which in turn drives the push ring 354 to move. This, in turn, drives the moving grinding head 353 to move, so that the moving grinding head 353 interacts with the fixed grinding head 353. The spacing between the grinding heads 33 is reduced or enlarged, and the bottom of the pre-tension spring 352 is connected to the top of the moving grinding head 353, so that the pre-tension spring 352 provides a limit and buffer for the moving grinding head 353, thereby adjusting the moving grinding head 353. The powder after grinding can fall into the collection container along the feed port 2, thereby adjusting the distance between the fixed grinding head 33 and the moving grinding head 353, making the grinding fineness adjustment structure simple and convenient and reducing the occupied area, making the later maintenance of the entire equipment simpler and more convenient.

[0045] When the grinder is no longer in use, slide the slide bar 632 to the right, causing the protrusion at one end of the slide bar 632 to press the two limiting blocks 634 to the opposite side, so that the slide bar 632 can be inserted into the gap between the two limiting blocks 634. After the slide bar 632 is inserted into the gap between the two limiting blocks 634, the spring outside the spring rod 635 will press the limiting blocks 634 back to their original position, so that the limiting blocks 634 lock the slide bar 632. When the grinder needs to be used again, slide the slide bar 632 to the right again so that the slip ring 633 passes through the gap formed by the two limiting blocks 634, and then pull the slide bar 632 to the left so that the slide bar 632 slides out of the button 631, so that the slide bar 632 releases the restriction on the button 631.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
