Description

Technical Field

[0001] This utility model relates to the field of powder dispensing needle technology, specifically a powder dispensing needle with a ball screw and a one-way bearing structure. Background Technology

[0002] Coffee is a beverage made from roasted and ground coffee beans. When brewing coffee, the coffee is ground into powder and then brewed with boiling water. However, because the coffee powder is not evenly distributed inside the coffee tray, a coffee maker is used to mix and stir the coffee powder inside the tray to improve the thoroughness of the mixing. Whether it is pour-over coffee extraction or espresso extraction, the goal is to make the coffee powder layer more uniform and avoid over-extraction or under-extraction.

[0003] In existing coffee brewing methods, a twisted metal plate is pressed down to generate rotational power, which drives the coffee needle to rotate and stir the coffee grounds in the portafilter. This can also mix the coffee grounds placed inside the coffee tray. However, this method has the disadvantages of large size, complex shape, and high cost. To address these issues, we have proposed a coffee needle with a ball screw and one-way bearing structure. Utility Model Content

[0004] To address the shortcomings of existing powder dispensing needles with ball screws and one-way bearings, this invention provides a powder dispensing needle with a ball screw and one-way bearing structure. This needle allows for synchronous rotation of the powder needle during the downward pressing process by pressing down on the handle to rotate the ball screw. Simultaneously, the spring's rebound action returns the device to its initial state, improving the efficiency of the powder dispensing needle and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a powder dispensing needle with a ball screw and a one-way bearing structure, including a magnetic chuck, a support component above the magnetic chuck, a height adjustment component inside the support component, a limit component threadedly installed in the height adjustment component, a rotatable ball screw sleeved in the limit component, and a mixing mechanism for stirring coffee powder fixed below the ball screw. A pressing component is installed above the ball screw. When the pressing component presses down on the ball screw, the ball screw is limited by the limit component, causing the mixing mechanism connected to the ball screw to rotate.

[0006] Preferably, the height adjustment component includes a limiting sleeve, the lower end of which is threadedly fitted inside the upper end of the support component, and the upper end of the limiting sleeve is threadedly fitted with a fastening nut installed on the upper end of the support component.

[0007] Preferably, the limiting component includes a bearing housing, and a set of pins is installed on both sides inside the bearing housing. At the same time, the bearing housing is threaded into the lower end of the limiting sleeve, and the inner side of the pins is movably sleeved into the interior of the spiral groove on the outside of the ball screw.

[0008] Preferably, the pressing component includes a handle sleeve, a handle is sleeved on the top end of the handle sleeve, the handle sleeve is sleeved inside the limiting sleeve, and a bearing is installed inside the lower end of the handle sleeve, wherein the bearing is sleeved inside the ball screw.

[0009] Preferably, a washer is mounted on the outside of the upper end of the ball screw, and a spring is mounted on the outside of the ball screw, wherein the spring is installed between the bearing seat and the washer.

[0010] Preferably, the mixing mechanism includes a needle plate, the bottom of which is fitted with a powder needle for mixing and stirring coffee powder, and the needle plate is sleeved on the outside of the lower end of the ball screw via a one-way bearing.

[0012] Compared with existing powder application devices with ball screws and one-way bearings, this utility model has the following advantages:

[0013] Beneficial effects:

[0014] 1. This powder dispenser with a ball screw and one-way bearing structure introduces the ball screw structure to the coffee industry, providing a smooth feel while also enhancing mechanical functionality and user comfort. When the handle is pressed down, the inner side of the pin engages with the spiral groove on the outside of the ball screw. As the ball screw is pressed down, the pin assists in controlling its synchronous rotation, which in turn drives the powder dispenser to contact and agitate the powder. Furthermore, the one-way bearing prevents the needle plate from springing back when the ball screw rebounds, thus avoiding interference with the powder mixing effect.

[0015] 2. The powder dispensing needle with ball screw and one-way bearing structure is installed by threaded connection of the equipment, with the handle sleeve and ball screw installed inside the adjusting nut, which improves the convenience of replacing the powder needle when the adjusting nut is installed inside the support component.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A powder dispensing needle with a ball screw and one-way bearing structure includes a magnetic chuck 1, a support component 2 above the magnetic chuck 1, and a height adjustment component inside the support component 2. The height adjustment component effectively adjusts the height of the mixing component. A limit component is threadedly installed in the height adjustment component. The limit component drives a pin 6 to engage with the inside of a spiral groove on the outside of the ball screw 7. A rotatable ball screw 7 is sleeved in the limit component, and a mixing mechanism for mixing coffee powder is fixed below the ball screw 7. The mixing mechanism mixes the powder tray placed at the lower end. A pressing component is installed above the ball screw 7. When the pressing component presses down on the ball screw 7, the ball screw 7 is limited by the limit component, causing the mixing mechanism connected to the ball screw 7 to rotate. The pressing component presses down to control the lower end of the ball screw 7 to move, and at the same time, the ball screw 7 drives the mixing mechanism to rotate, and the mixing mechanism mixes and stirs the coffee powder.

[0024] Please see Figure 3The height adjustment component includes a limiting sleeve 3. The lower end of the limiting sleeve 3 is threadedly fitted inside the upper end of the support component 2. The upper end of the limiting sleeve 3 is threadedly fitted with a fastening nut 4 installed on the upper end of the support component 2. By rotating the limiting sleeve 3, the limiting sleeve 3 and the upper end of the support component 2 move threadedly, allowing the user to adjust the height of the limiting sleeve 3 inside the support component 2. At the same time, rotating the fastening nut 4 installed on the upper end of the limiting sleeve 3 causes the fastening nut 4 to move downward, thus maintaining stability when the fastening nut 4 drives the limiting sleeve 3 to be installed inside the support component 2.

[0025] Please see Figure 3 The limiting component includes a bearing seat 5, with a set of pins 6 installed on both sides inside the bearing seat 5. The bearing seat 5 is threaded into the lower end of the limiting sleeve 3. The inner side of the pins 6 is movably sleeved into the spiral groove on the outside of the ball screw 7. By installing the pins 6 inside the bearing seat 5 and the bearing seat 5 being spirally installed inside the lower end of the limiting sleeve 3, the bearing seat 5 drives the pins 6 to engage in the spiral groove on the outside of the ball screw 7. When the pressing component presses down on the ball screw 7, the pins 6 move inside the spiral groove on the outside of the ball screw 7, thereby driving the ball screw 7 to rotate. The ball screw 7 drives the mixing mechanism to rotate, and the mixing mechanism can then mix and stir the coffee powder.

[0026] Please see Figure 1 and Figure 5 The pressing component includes a handle sleeve 11, with a handle 12 fitted onto the top of the handle sleeve 11. The handle sleeve 11 is fitted inside the limiting sleeve 3, and a bearing 8 is installed inside the lower end of the handle sleeve 11. The bearing 8 is fitted inside the ball screw 7 and installed inside the limiting sleeve 3 via the handle sleeve 11. At the same time, the upper end of the ball screw 7 is installed inside the handle sleeve 11 via the bearing 8. The bearing 8 reduces the frictional resistance when the ball screw 7 rotates. Pressing the handle 12 downward pushes the handle sleeve 11 downward, and at the same time, the ball screw 7 can drive the mixing mechanism to stir.

[0027] Please see Figure 5 A washer 9 is mounted on the upper part of the ball screw 7, and a spring 10 is mounted on the outer side of the ball screw 7. The spring 10 is installed between the bearing seat 5 and the washer 9. By pressing the handle 12, the washer 9 is moved downward. After the pressing of the handle 12 is stopped, the ball screw 7 returns to its initial state under the elastic action of the spring 10, thus maintaining the convenience of resetting the ball screw 7.

[0028] Please see Figure 2The mixing mechanism includes a needle plate 14, with a powder needle 15 for mixing and stirring coffee powder installed at the bottom of the needle plate 14. The needle plate 14 is sleeved on the outside of the lower end of the ball screw 7 via a one-way bearing 13. A one-way bearing 13 is installed on the inside of the needle plate 14. When the ball screw 7 moves downward and rotates, it can drive the needle plate 14 to rotate synchronously. At the same time, when the ball screw 7 rebounds and rotates, the one-way rotation of the one-way bearing 13 limits the position of the needle plate 14, preventing the needle plate 14 from rotating in the opposite direction.

[0029] Please see Figure 3 The magnetic chuck 1 has a positioning hole 16 inside. A powder tray is placed inside the magnetic chuck 1. The magnetic chuck 1 can be driven to be snapped onto the iron positioning post through the positioning hole 16. At the same time, the magnetic chuck 1 is magnetically attracted to it to ensure the stability of the powder dispensing needle during use.

[0030] Working principle: When in use, place the coffee trolley inside the magnetic chuck 1, which is fixed by a magnetic device. Press down the handle 12, which pushes the ball screw 7 downward, causing the coffee needle 15 to contact the coffee trolley. The ball screw 7 has a spiral groove on its outside, and the pin 6 is movably sleeved inside the spiral groove, causing the ball screw 7 to rotate synchronously. This causes the coffee needle 15 to stir the coffee powder inside the coffee trolley. At the same time, the spring 10 can push the pad 9 upward, so that the ball screw 7 returns to its initial state. Under the action of the one-way bearing 13, the needle plate 14 is prevented from rotating synchronously.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
