Description

Technical Field

[0001] This disclosure relates to the field of coffee tool technology, and in particular to a manual coffee powder dispenser and coffee powder dispensing device. Background Technology

[0002] After coffee beans are ground into powder, some of the ground coffee powder will clump together. If the brewing process continues, the coffee will not be brewed sufficiently, which will affect the taste of the brewed coffee.

[0003] Therefore, the existing patent CN212650722U discloses a coffee needle-type powder dispenser, including a handheld part, a base part, and a needle-type panel; the bottom surface of the base part is provided with a groove; the handheld part is located on the upper part of the base part, and there is a gap between the handheld part and the base part and they are rotatably connected; the needle-type panel is located inside the groove part, and the bottom surface of the needle-type panel is provided with several needles that are connected and fixed thereto, with the bottom end of the needles protruding from the bottom surface of the groove part; the upper part of the needle-type panel is connected and fixed to the handheld part through a connecting rod that passes through the base part, so that the needle-type panel can be rotated by rotating the handheld part, and then the needles will follow the rotation.

[0004] Although this solution can loosen coffee powder and make it easier to extract, when loosening coffee powder, the needle panel and the handpiece rotate in concentric circles synchronously. That is, when the handpiece rotates once, the needle panel also rotates once. In other words, when the handpiece is manually rotated once, the needle panel can only follow the handpiece to rotate once. This makes the coffee powder distribution effect relatively simple and the work efficiency low. Utility Model Content

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

[0032] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0033] Please see Figure 1 and Figure 2This is a manual powder applicator 10 according to an embodiment of the present invention, comprising a rotating assembly 100, a base assembly 200, and a powder applicator 300. The rotating assembly 100 includes a handle 110, a spring 120, a spiral rod 130, and a screw sleeve 140. The spiral rod 130 is movably connected to the handle 110. The handle 110 has an interconnected mounting port 111 and a mounting cavity 112. The screw sleeve 140 passes through the mounting port 111 and the mounting cavity 112 in sequence, and is spirally mounted on the spiral rod 130. The outer wall of the screw sleeve 140 has a protruding abutment ring 141. The pressure end of the spiral rod 130, the abutment ring 141, and the spring 120 are all located in the mounting cavity 112. The abutment ring 141 is located adjacent to the mounting port 111. The two ends of the spring 120 abut against the abutment ring 141 and the inner wall of the handle 110, respectively. 20 is also arranged around the outside of the screw rod 130 and the outside of the screw sleeve 140; the base assembly 200 includes a base body 210 and a base support 220 connected to each other. Specifically, the base body 210 and the base support 220 are engaged. The base support 220 has a receiving cavity 220a and the base body 210 has a clearance opening 211. The receiving cavity 220a communicates with the clearance opening 211. The screw sleeve 140 is fixedly connected to the base support 220. Another part of the screw sleeve 140 is exposed between the handle 110 and the base support 220. The rotating end of the screw rod 130 is located in the receiving cavity 220a; the powder distribution assembly 300 is arranged at the rotating end of the screw rod 130. The powder distribution assembly 300 is located in the receiving cavity 220a. The powder distribution assembly 300 is used to disperse the coffee powder in the coffee powder cup after passing through the clearance opening 211. It can be understood that the pressure-bearing end of the spiral rod 130 is the end located within the mounting cavity 112; the rotating end of the spiral rod 130 is the end located within the receiving cavity 220a, and the pressure-bearing end and the rotating end of the spiral rod 130 are oppositely arranged ends. Furthermore, the powder application assembly 300 is movably disposed at the rotating end of the spiral rod 130, so that the powder application assembly 300 rotates around the spiral rod 130 as the center.

[0034] In this embodiment, the screw rod 130 has an external thread, while the screw sleeve 140 has an internal thread. After the coffee powder cup is fixed, when the handle 110 is pressed down by hand, the handle 110 moves downward, driving the screw rod 130. Through the engagement of the external and internal threads, the screw rod 130 moves downward in a spiral rotation, thereby driving the powder distribution assembly 300 to rotate. During this process, the rotating end of the screw rod 130 gradually moves away from the screw sleeve 140, causing the powder distribution assembly 300 to gradually approach the coffee powder cup. The powder distribution assembly 300 passes through and avoids the coffee powder cup. After the coffee powder is stirred at port 211, one side of spring 120 abuts against the abutment ring 141, while the screw sleeve 140 is fixed. At this time, spring 120 will be subjected to a certain downward pressure. When no more force is applied to handle 110, due to the elasticity of spring 120, handle 110 moves upward under the action of spring 120, thereby driving screw rod 130 to move upward in a spiral rotation until handle 110 returns to its original position. At this time, powder distribution assembly 300 does not rotate or rotates in the opposite direction.

[0035] Furthermore, the powder application assembly 300 can be unidirectionally movable at the shaft end of the spiral rod 130, so that when the spiral rod 130 moves downward, it drives the powder application assembly 300, and when the spiral rod 130 moves upward, the powder application assembly 300 does not rotate with the spiral rod 130; the powder application assembly 300 can also be fixedly installed at the shaft end of the spiral rod 130, so that when the spiral rod 130 moves downward, it drives the powder application assembly 300, and when the spiral rod 130 moves upward, the powder application assembly 300 rotates in the opposite direction with the spiral rod 130.

[0036] In the above embodiments, the rotating assembly 100 includes a handle 110, a spring 120, a screw rod 130, and a screw sleeve 140. When the user presses down on the handle 110, the handle 110 moves downward, driving the screw rod 130 to move downward. Since the screw rod 130 and the screw sleeve 140 are engaged through corresponding threaded parts, the screw rod 130 moves downward in a spiral manner relative to the screw sleeve 140, thereby driving the powder distribution assembly 300 to rotate and move closer to the coffee powder receiving cup containing coffee powder, so that the powder distribution assembly 300 can disperse the coffee powder. In this way, when pressed once, the powder distribution assembly 300 can rotate several times, which improves the efficiency of coffee powder distribution.

[0037] like Figures 2 to 4As shown, in one embodiment, the rotating assembly 100 further includes a steel ball rotating component 150, which is located in the mounting cavity 112. The steel ball rotating component 150 includes an upper rotating ball plate component 151, a pressure plate 152, and a lower rotating ball plate component 153. The pressure plate 152 is connected to the inner wall of the handle 110 and is movably arranged around the outside of the screw rod 130 so that the screw rod 130 is movably connected to the pressure plate 152. The upper rotating ball plate component 151 and the lower rotating ball plate component 153 are connected to the outer wall of the screw rod 130, and the upper rotating ball plate component 151, the pressure plate 152, and the lower rotating ball plate component 153 are arranged sequentially in the vertical direction. The two sides of the spring 120 abut against the pressure plate 152 and the abutting ring 141, respectively. It is understandable that when using the manual coffee powder dispenser 10, when the handle 110 is pressed down, the handle 110 moves downward. At this time, the pressure plate 152 contacts the lower rotating bead plate component 153, and the lower rotating bead plate component 153 and the screw rod 130 rotate downward synchronously, so that the powder dispensing component 300 gradually approaches the coffee powder and performs a stirring action. When the pressure on the handle 110 is no longer applied, the spring 120 applies pressure to the pressure plate 152 with its own elasticity, so that it contacts the upper rotating bead plate component 151. At this time, the upper rotating bead plate component 151 and the screw rod 130 rotate upward synchronously, so that the powder dispensing component 300 gradually moves away from the coffee powder.

[0038] Furthermore, such as Figure 4 As shown, the upper rotating ball bearing component 151 includes an upper ball bearing disk 1511 and multiple upper ball bearings 1512. The upper ball bearing disk 1511 is connected to the outer wall of the screw rod 130. The upper ball bearing disk 1511 has an upper circular groove, and each upper ball bearing 1512 is located in a corresponding upper circular groove. The openings of the multiple upper circular grooves face the pressure plate 152. Thus, when the handle 110 is no longer pressed, the spring 120, with its own elasticity, presses the pressure plate 152 upward, causing it to contact the upper ball bearings 1512 of the upper rotating ball bearing component 151. At this time, the upper ball bearing disk 1511 rotates upward synchronously with the screw rod 130 under the rotation of the upper ball bearings 1512. During this process, the rolling of the upper ball bearings 1512 can indirectly reduce the rotational resistance of the screw rod 130 when it moves upward, making it easier for the screw rod 130 to return to its initial position under the action of the spring 120. Therefore, the handle 110 can more easily return to its original position under the action of the upper ball bearings 1512.

[0039] Furthermore, such as Figure 4As shown, the lower rotating bead disc component 153 includes a lower steel ball disc 1531 and multiple lower steel balls 1532. The lower steel ball disc 1531 is connected to the outer wall of the screw rod 130. The lower steel ball disc 1531 has a lower circular groove, and each lower steel ball 1532 is located in a corresponding lower circular groove. The openings of the multiple lower circular grooves face the pressure plate 152. Thus, when the handle 110 is pressed down, the handle 110 moves downward. At this time, the pressure plate 152 contacts the lower steel balls 1532 of the lower rotating bead disc component 153. Under the rotation of the lower steel balls 1532, the lower steel ball disc 1531 rotates downward synchronously with the screw rod 130, thereby causing the powder distribution component 300 to gradually approach the coffee powder and perform a stirring action. During this process, the rolling of the lower steel balls 1532 can indirectly reduce the rotational resistance of the screw rod 130 when it moves downward, making it easier for the screw rod 130 to move downward and for the powder distribution component 300 to better disperse the coffee powder. In this embodiment, the upper steel ball disk 1511, upper steel ball 1512, pressure plate 152, lower steel ball 1532 and lower steel ball disk 1531 are arranged in sequence along the vertical direction.

[0040] Furthermore, such as Figure 4 As shown, a portion of the structure of each upper steel ball 1512 is located in the corresponding upper circular groove, and the remaining portion of the structure of each upper steel ball 1512 is exposed between the upper steel ball disk 1511 and the pressure plate 152, so that an upper rotation gap is formed between the upper steel ball disk 1511 and the pressure plate 152; a portion of the structure of each lower steel ball 1532 is located in the corresponding lower circular groove, and the remaining portion of the structure of each lower steel ball 1532 is exposed between the lower steel ball disk 1531 and the pressure plate 152, so that a lower rotation gap is formed between the lower steel ball disk 1531 and the pressure plate 152.

[0041] In another embodiment, the pressure plate 152 divides the mounting cavity 112 into a first mounting cavity and a second mounting cavity, wherein the upper rotating bead plate component 151 is located in the first mounting cavity, and the lower rotating bead plate component 153, the spring 120, the screw rod 130, the screw sleeve 140 and the abutment ring 141 are all located in the second mounting cavity.

[0042] like Figure 2 and Figure 7As shown, in one embodiment, the base support 220 includes a support body 221 and an adjustment knob 222. A receiving cavity 220a is disposed within the support body 221. The adjustment knob 222 is connected to the screw sleeve 140. The support body 221 has a threaded hole 221a that communicates with the receiving cavity 220a. A spiral portion 2221 is provided on the outer side of the adjustment knob 222, and the spiral portion 2221 is located within the threaded hole 221a, so that the support body 221 and the adjustment knob 222 are spirally connected. It can be understood that when the adjustment knob 222 is used, the user can rotate the adjustment knob 222 to adjust the distance of the entire rotating assembly 100 relative to the base support 220. Specifically, rotating the adjustment knob 222 adjusts the vertical position of the screw sleeve 140, causing the screw sleeve 140 to move up and down, indirectly causing the powder distribution assembly 300 to move up and down to adapt to coffee powder cups of different depths.

[0043] Furthermore, such as Figure 6 and Figure 7 As shown, the adjusting knob 222 has a spiral mounting hole 222a, which communicates with the receiving cavity 220a. The outer side of the screw sleeve 140 has a mounting screw portion 142, which is located inside the spiral mounting hole 222a, so that the screw sleeve 140 passes through the spiral mounting hole 222a. Figure 2 As shown. It can be understood that when installing the screw sleeve 140, it can be installed with the adjusting knob 222 through a threaded connection, thus forming part of the structure of the manual powder distributor 10. During the process, only rotation is required for screw installation, and no other tools are needed to assemble it, which is highly convenient.

[0044] like Figure 2 and Figure 7 As shown, in one embodiment, the base assembly 200 further includes multiple magnetic connectors 230, and the base body 210 has multiple magnetic mounting slots 212, with the magnetic connectors 230 disposed in corresponding magnetic mounting slots 212. It is understood that when multiple magnetic connectors 230 are used, the coffee powder cup used for receiving coffee powder is typically made of stainless steel. During the powder dispensing step, the edge of the coffee cup is magnetically connected to the magnetic connector 230, causing the coffee powder cup to magnetically engage with the manual powder dispenser 10. Then, the coffee powder is dispensed by pressing down the handle 110. During this process, the coffee powder cup is less likely to detach from the manual powder dispenser 10, ensuring the stability of the coffee powder dispensing process. Furthermore, the opening direction of the magnetic mounting slot 212 is opposite to that of the base bracket 220.

[0045] like Figure 2 , Figures 5 to 8As shown, in one embodiment, the powder application assembly 300 includes a needle holder 310, a one-way bearing 320, and a plurality of powder application needles 330. The plurality of powder application needles 330 are all disposed on the side of the needle holder 310 away from the screw sleeve 140. The needle holder 310 has an installation channel 311 and a rotating shaft channel 312 that are sequentially connected. The rotating shaft end of the spiral rod 130 passes through the rotating shaft channel 312 and the installation channel 311 in sequence. The one-way bearing 320 abuts against the side wall of the installation channel 311. The one-way bearing 320 and the needle holder 310 are both movably disposed on the rotating shaft end of the spiral rod 130. It is understandable that when the screw rod 130 rotates, it will drive the one-way bearing 320 to rotate, which in turn drives the needle holder 310 to rotate synchronously with the screw rod 130 through the one-way bearing 320. The one-way bearing 320 has the characteristic of being able to rotate freely in one direction and locked in the other direction. Thus, the one-way bearing 320 drives the needle holder 310 to rotate. Since the powder dispensing needle 330 is set on the needle holder 310, the powder dispensing needle 330 rotates with the needle holder 310, thereby dispersing the coffee powder. When the handle 110 moves down to the bottom, the screw rod 130 no longer acts on the one-way bearing 320, and the needle holder 310 continues to rotate due to its own inertia. Thus, the powder dispensing needle 330 rotates with the needle holder 310. In this way, as long as the handle 110 is pressed down once, the needle holder 310 can rotate several times, thereby improving the efficiency of coffee powder dispensing. Meanwhile, under the action of the one-way bearing 320, when the spiral rod 130 moves downward in a spiral motion, it will drive the needle holder 310 to rotate to perform the powder dispensing operation. When the handle 110 returns to its original position, the one-way bearing 320 no longer interacts with the needle holder 310, and thus, when the spiral rod 130 moves upward in a spiral motion, it will not drive the needle holder 310 to rotate. Furthermore, multiple powder dispensing needles 330 are mounted on the needle holder 310 by magnetic means or by snap-fit, and are staggered in distribution.

[0046] like Figure 5 , Figure 6 and Figure 8 As shown, in one embodiment, the powder dispensing assembly 300 further includes a screw 340. The shaft end of the spiral rod 130 is provided with an internal threaded hole 131. The threaded portion of the screw 340 is located in the internal threaded hole 131, and the top of the screw 340 abuts against the spiral rod 130 and the one-way bearing 320 respectively, to prevent the one-way bearing 320 and the needle holder 310 from falling off when the coffee powder is dispensed.

[0047] This disclosure also provides a coffee powder distribution device, including the manual powder distributor 10 of any of the above embodiments.

[0048] Compared with the prior art, this disclosure has at least the following advantages:

[0049] The aforementioned manual coffee powder dispenser 10, in its rotating assembly 100, comprises a handle 110, a spring 120, a screw rod 130, and a screw sleeve 140. When the user presses down on the handle 110, the handle 110 moves downward, causing the screw rod 130 to move downward as well. Since the screw rod 130 and the screw sleeve 140 are engaged by corresponding threaded parts, the screw rod 130 moves downward in a spiral motion relative to the screw sleeve 140, thereby causing the coffee powder dispensing assembly 300 to rotate and move closer to the coffee powder receiving cup containing coffee powder, so that the coffee powder dispensing assembly 300 can disperse the coffee powder. Thus, when pressed once, the coffee powder dispensing assembly 300 can rotate several times, which improves the efficiency of coffee powder dispensing.

[0050] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
