Description

Technical Field

[0001] The present disclosure relates to the field of coffee processing tools, and particularly to a pressing needle type powder distributor and a coffee powder distribution device. Background Art

[0002] Currently, with the rise of coffee culture, the demand for coffee making tools is also increasing continuously. At the same time, Italian coffee is the mainstream demand of most people. However, when making Italian coffee, because the particles of Italian coffee powder are ground finer, the coffee powder is prone to produce oil, resulting in the situation of coffee powder caking. In response to this situation, some manufacturers have produced a coffee stirrer to solve this problem.

[0003] For example, Chinese Patent Document CN221205169U discloses a coffee stirrer, which includes a fixed ring; a vertical cylinder installed at the center of the fixed ring, with a spiral blade movably arranged up and down inside, and a guiding groove for guiding the rotation of the spiral blade is opened at the bottom of the vertical cylinder; a pressing head installed on the top of the spiral blade for pressing; a rotating frame connected to the bottom end of the spiral blade through a rotating mechanism, and a stirring rod for stirring is installed at the bottom of the rotating frame. Pressing down the pressing head can make the spiral blade move downwards. When the spiral blade moves downwards, it rotates under the guiding action of the guiding groove, so as to achieve the effect of rotating and moving downwards. The spiral blade rotates and moves downwards to drive the rotating frame to rotate and move downwards through the rotating mechanism, and the rotating frame rotates and moves downwards to stir the material through the stirring rod.

[0004] However, the above design of the coffee stirrer has the following problems:

[0005] For the above coffee stirrer, although pressing down the pressing head can make the spiral blade move downwards, and the spiral blade rotates under the action of the guiding groove when moving downwards, so as to achieve the effect of rotating and moving downwards, but because the pressing head is repeatedly pressed down for a long time to make the spiral blade move downwards, the spiral blade and the guiding groove repeatedly rub against each other, resulting in damage to the structure of the guiding groove, making it difficult for the spiral blade to rotate on the guiding groove, which is not conducive to the rotation and downward movement of the rotating frame.

[0012] In one embodiment, equidistant threads are provided on the inner cavity wall of the guiding and pushing middle cylinder, and the equidistant threads extend along the axial direction of the guiding and pushing middle cylinder; the guiding spiral groove is formed between two adjacent thread segments of the equidistant threads.

[0018] A coffee powder distributing device includes the pressing needle type powder distributor described in any one of the above embodiments.

[0019] Compared with the prior art, the present disclosure has at least the following advantages:

[0020] 1) By arranging the pressing and pushing assembly at the first end of the guiding and pushing middle cylinder, and extending the pushing part into the inner cavity of the guiding and pushing middle cylinder, the end of the pushing part slides through the second end of the guiding and pushing middle cylinder, so that the powder distributing mechanism is arranged at the end of the pushing part.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] To better understand the technical solutions and beneficial effects of the present disclosure, the following further describes the present disclosure in detail with specific embodiments:

[0030] As Figure 1As shown in the figure, the pressing needle-type powder distributor 10 of an embodiment includes a pressing and pushing assembly 100, a guiding and pushing middle cylinder 200, and a powder distributing mechanism 300; the pressing and pushing assembly 100 is arranged to move up and down at the first end of the guiding and pushing middle cylinder 200, and a pushing part 110 extends into the inner cavity of the guiding and pushing middle cylinder 200; the end of the pushing part 110 slidably penetrates through the second end of the guiding and pushing middle cylinder 200, and the powder distributing mechanism 300 is arranged at the end of the pushing part 110; a guiding spiral groove 210 is formed on the inner cavity wall of the guiding and pushing middle cylinder 200; the guiding spiral groove 210 is arranged in a spiral shape around the circumferential direction of the pushing part 110 and extends towards the second end of the guiding and pushing middle cylinder 200; a friction abutting part 1110 protrudes from the pushing part 110 into the guiding spiral groove 210; the friction abutting part 1110 slidably abuts against the groove wall of the guiding spiral groove 210, so that the pushing part 110 rotates the powder distributing mechanism 300 along the guiding spiral groove 210.

[0031] It can be understood that by arranging the pressing and pushing assembly 100 at the first end of the guiding and pushing middle cylinder 200, and at the same time extending the pushing part 110 into the inner cavity of the guiding and pushing middle cylinder 200, the end of the pushing part 110 slidably penetrates through the second end of the guiding and pushing middle cylinder 200, so that the powder distributing mechanism 300 is arranged at the end of the pushing part 110. Because a guiding spiral groove 210 is formed in the inner cavity of the guiding and pushing middle cylinder 200, and at the same time the guiding spiral groove 210 is arranged in a spiral shape around the circumferential direction of the pushing part 110, and at the same time the guiding spiral groove 210 extends towards the second end of the guiding and pushing middle cylinder 200, and a friction abutting part 1110 protrudes from the pushing part 110 into the guiding spiral groove 210, so that the friction abutting part 1110 slidably abuts against the guiding spiral groove 210. When the pressing and pushing assembly 100 moves downward, the friction abutting part 1110 of the pushing part 110 will move downward along the path of the guiding spiral groove 210, so that the pushing part 110 rotates the powder distributing mechanism 300 along the guiding spiral groove 210, and the powder distributing mechanism 300 moves downward; by arranging the guiding spiral groove 210 in a spiral shape around the circumferential direction of the pushing part 110 and extending towards the second end of the guiding and pushing middle cylinder 200, the friction path of the pushing part 110 becomes longer. When the pushing part 110 moves downward, it will not repeatedly rub in the same place, avoiding the influence on the smoothness of the pressing and pushing assembly 100 due to the single friction of the inner wall structure of the guiding and pushing middle cylinder 200.

[0032] It can be understood that compared with the prior art, in the above-mentioned pressing needle-type powder distributor 10, by arranging the guiding spiral groove 210 in a spiral shape around the circumferential direction of the pushing part 110, the friction path of the guiding and pushing middle cylinder 200 becomes longer, thereby reducing the situation of repeatedly rubbing the inner wall structure, avoiding repeatedly rubbing the pushing part 110 at the same position, reducing the situation that the inner wall structure of the guiding and pushing middle cylinder 200 is worn due to sliding friction, protecting the structure of the guiding and pushing middle cylinder 200, and enabling the pressing and pushing assembly 100 to drive the powder distributing mechanism 300 more smoothly.

[0033] As Figure 1 shown, in one embodiment, the pressing and pushing assembly 100 includes a pressing handle 120 and a torsion push rod 130; the pressing handle 120 is slidably sleeved on the first end of the guiding and pushing middle cylinder 200; the torsion push rod 130 is arranged to move up and down in the inner cavity of the guiding and pushing middle cylinder 200, and the first end of the torsion push rod 130 abuts against the pressing handle 120; the second end of the torsion push rod 130 slidably penetrates through the second end of the guiding and pushing middle cylinder 200 and is connected to the powder distributing mechanism 300; the friction holding part 1110 is arranged on the torsion push rod 130. It can be understood that the pressing handle 120 is slidably sleeved on one end of the guiding and pushing middle cylinder 200, and at the same time the torsion push rod 130 is arranged to move up and down in the inner cavity of the guiding and pushing middle cylinder 200. Because the first end of the torsion push rod 130 abuts against the pressing handle 120, and the second end of the torsion push rod 130 slidably penetrates through the second section of the guiding and pushing middle cylinder 200, when the pressing handle 120 is pressed and rotated downward, the torsion push rod 130 will rotate downward synchronously along the direction of the guiding and pushing middle cylinder 200. At the same time, because the torsion push rod 130 is connected to the powder distributing mechanism 300, and the friction holding part 1110 is arranged on the torsion push rod 130, the friction holding part 1110 will move downward along the guiding spiral groove 210, so that the torsion push rod 130 drives the powder distributing mechanism 300 to rotate downward, so that the powder distributing mechanism 300 achieves the powder distributing effect.

[0034] As Figure 1 shown, in one embodiment, the torsion push rod 130 includes a friction body 1310 and a connecting rod body 1320 which are connected; the friction body 1310 is close to and abuts against the pressing handle 120; the connecting rod body 1320 slidably penetrates through the second end of the guiding and pushing middle cylinder 200 and is connected to the powder distributing mechanism 300; the friction holding part 1110 is arranged on the friction body 1310. It can be understood that the friction body 1310 is close to and abuts against the pressing handle 120. When the pressing handle 120 is pressed downward, the friction body 1310 will rotate downward along the track of the guiding spiral groove 210. Also, because the connecting rod body 1320 slidably penetrates through the guiding and pushing middle cylinder 200 and is connected to the powder distributing mechanism 300, when the friction body 1310 rotates downward, it drives the connecting rod body 1320 to move downward, and the connecting rod body 1320 is connected to the powder distributing mechanism 300, so that the friction body 1310 drives the powder distributing mechanism 300 to rotate downward when moving downward.

[0035] As Figure 1As shown, in one embodiment, the inner cavity wall of the guiding and pushing middle cylinder 200 is provided with equidistant threads 220, and the equidistant threads 220 extend along the axial direction of the guiding and pushing middle cylinder 200; a guiding rotation groove 210 is formed between two adjacent thread segments of the equidistant threads 220. It can be understood that by providing the equidistant threads 220 on the inner cavity wall of the guiding and pushing middle cylinder 200 and the equidistant threads 220 extending along the axial direction of the guiding and pushing middle cylinder 200, the inner cavity wall of the guiding and pushing middle cylinder 200 forms the guiding rotation groove 210, so that the friction abutting portion 1110 slides and abuts against the guiding rotation groove 210, thereby enabling the pushing portion 110 to drive the powder distributing mechanism 300 to move along with the rotation of the guiding groove.

[0036] Combined with Figure 1 and Figure 2 As shown, specifically, a compression spring 400 is arranged in the inner cavity of the guiding and pushing middle cylinder 200; the compression spring 400 is sleeved on the connecting rod body 1320; one end of the compression spring 400 abuts against the friction body 1310, and the other end of the compression spring 400 abuts against the bottom of the guiding and pushing middle cylinder 200. It can be understood that since one end of the compression spring 400 abuts against the friction body 1310, when the friction body 1310 moves downward along the guiding rotation groove 210, the compression spring 400 will be compressed downward along with the friction body 1310. At the same time, since one end of the connecting rod body 1320 is connected to the friction body 1310 and the other end is connected to the powder distributing mechanism 300, when the friction body 1310 moves downward, it will drive the powder distributing mechanism 300 to rotate downward. When the pressing handle 120 is released, since the friction body 1310 no longer moves downward under the action of force, the compression spring 400 will press the pressing handle 120 to reset upward according to the spring force, so that the friction body 1310 also resets upward, enabling the powder distributing mechanism 300 to return to the position without force, achieving the function of resetting the powder distributing mechanism 300 and the pressing handle 120 by the elastic force of the compression spring 400.

[0037] Combined with Figure 1 and Figure 2As shown, in one embodiment, the pressing needle type powder distributor 10 further includes a locking member 600 and a bracket 500; the bracket 500 is provided with an adjustment cavity 510, the second end of the guiding and pushing middle cylinder 200 passes through the adjustment cavity 510 and is threadedly connected to the cavity wall of the adjustment cavity 510; the powder distributing mechanism 300 is located inside the bracket 500; the locking member 600 is screwed to the guiding and pushing middle cylinder 200 and abuts against the bracket 500. It can be understood that the adjustment cavity 510 is provided in the bracket 500, and the second section of the guiding and pushing middle cylinder 200 passes through the adjustment cavity 510, so that the guiding and pushing middle cylinder 200 is threadedly connected to the cavity wall of the adjuster, enabling the guiding and pushing middle cylinder 200 to adjust the distance between the powder distributing mechanism 300 and the powder bowl, thus achieving the function of deep adjustment of the powder distributing mechanism 300. When the depth of the powder distributing mechanism 300 is adjusted, the powder distributing mechanism 300 can be fixed by screwing the locking member 600 to the guiding and pushing middle cylinder 200 to prevent the powder distributing mechanism 300 from sliding downwards.

[0038] Combined with Figure 1 and Figure 2 As shown, in one embodiment, the powder distributing mechanism 300 includes a rotating bearing 310 and a rotating needle holder 320. The rotating bearing 310 is sleeved on the connecting rod body 1320, and the rotating bearing 310 is fixedly connected to the rotating needle holder 320. It can be understood that by sleeving the rotating bearing 310 on the connecting rod body 1320 and fixedly connecting the rotating bearing 310 to the rotating needle holder 320, when the connecting rod body rotates to drive the rotating needle holder 320 to slide downwards, using the rotating bearing 310 to sleeve the rotating needle holder 320 can reduce the friction between the rotating needle holder 320 and the connecting rod body 1320, improve the smoothness and efficiency of the downward sliding movement of the rotating needle holder 320, and at the same time reduce the friction between the rotating needle holder 320 and the connecting rod body 1320. At the same time, the rotating bearing 310 can stably support the rotating needle holder 320 to ensure its stability during rotation, reduce the situation of deviation and vibration, and the rotating bearing 310 can effectively bear and distribute the load generated by the rotating needle holder 320 during movement, protecting the rotating needle holder 320 and the connecting rod body 1320 from excessive wear.

[0039] Combined with Figure 1 and Figure 2As shown, in one embodiment, the rotary needle holder 320 includes a stirring turntable 3210 and a plurality of stirring needles 321a. The stirring turntable 3210 extends circumferentially with a plurality of racks 3211. At least one stirring needle 321a is provided on each rack 3211, and each stirring needle 321a extends downward. It can be understood that a plurality of racks 3211 are arranged circumferentially on the stirring turntable 3210, and at least one stirring needle 321a is provided on each rack 3211. When the connecting rod body 1320 rotates downward, the stirring turntable 3210 is driven to rotate downward, so that the stirring needles 321a on the racks 3211 rotate downward to stir the coffee powder in the powder bowl, making the coffee powder evenly stirred.

[0040] Combined with Figure 1 With Figure 2 As shown, in one embodiment, the rotary needle holder 320 further includes a plurality of counterweight columns 3220, and each counterweight column 3220 is correspondingly arranged on one rack 3211. It can be understood that a configuration column is correspondingly arranged on each rack 3211. Because the counterweight columns 3220 generate a weight deviation, when the friction body 1310 and the connecting rod body rotate, the number of rotations of the rotary needle holder 320 is always greater than the number of rotations of the friction body 1310 and the connecting rod body 1320, enabling the powder distribution mechanism 300 to complete the stirring of the coffee powder more efficiently. At the same time, because the counterweight columns 3220 generate weight and are fixed on the rotary needle holder 320, the impact of the rotary needle holder 320 on the coffee powder during powder distribution is stronger, and the agglomerated coffee powder can be better stirred evenly.

[0041] This application also provides a coffee powder distribution device, including the pressing needle type powder distributor 10 described in any of the above embodiments. It can be understood that by arranging the guiding spiral groove 210 to surround the pushing portion 110 circumferentially in a spiral shape, the friction path of the guiding and pushing middle cylinder 200 becomes longer, thereby reducing the situation of repeatedly rubbing the inner wall structure, avoiding repeatedly rubbing the pushing portion 110 at the same position, reducing the wear of the inner wall structure of the guiding and pushing middle cylinder 200 caused by sliding friction, protecting the structure of the guiding and pushing middle cylinder 200, and enabling the pressing and pushing assembly 100 to drive the powder distribution mechanism 300 more smoothly.

[0042] Compared with the prior art, the present disclosure has at least the following advantages:

[0043] 1) By arranging the pressing and pushing component 100 at the end of the threaded middle cylinder, and the pushing end of the pressing and pushing component 100 sliding through the sliding cavity of the threaded middle cylinder and connecting with the powder distributing mechanism 300, the pressing and pushing component 100 can push the powder distributing mechanism 300 to move. Also, because the sliding cavity is provided with equidistant threads 220, the pressing and pushing component 100 moves downward along the equidistant threads 220. And since the pressing and pushing component 100 is connected with the powder distributing mechanism 300, the powder distributing mechanism 300 is driven to rotate downward by the pressing and pushing component 100, thus achieving the effect of powder distribution. Because the pressing and pushing component 100 extends and moves along the equidistant threads 220 in the sliding cavity, and at the same time the equidistant threads 220 extend in the sliding cavity towards the powder distributing mechanism 300, the friction area between the pressing and pushing component 100 and the threaded middle cylinder is reduced, and the inner wall structure of the threaded middle cylinder is less likely to be worn.

[0044] 2) Compared with the prior art, in the above-mentioned pressing needle-type powder distributor 10, the pressing and pushing component 100 is slidably arranged in the sliding cavity, and the sliding cavity is provided with equidistant threads 220 which extend towards the powder distributing mechanism 300 in the sliding cavity. So that the pressing and pushing component 100 slides downward along the equidistant threads 220. At the same time, because the pressing and pushing component 100 is connected to the powder distributing mechanism 300, when the pressing and pushing component 100 slides downward, it drives the powder distributing mechanism 300 to rotate downward. The pressing and pushing component 100 slides downward along the equidistant threads 220 of the threaded middle cylinder, reducing the situation that the inner wall structure of the threaded middle cylinder is worn due to sliding friction, thereby improving the smoothness of the movement of the pressing and pushing component 100 in the threaded middle cylinder.

[0045] The above embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several deformations and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
