Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of coffee powder distributor, in particular to a height adjusting structure and coffee powder distributor. BACKGROUND

[0002] The coffee powder distributor plays an important role in the process of making espresso coffee, and its main functions include scattering and distributing coffee powder. In the related art, the coffee powder distributor generally includes a top cover, a support and a powder distribution paddle. When it is necessary to scatter and distribute the coffee powder in the powder bowl, the support is first placed and positioned at the bowl opening of the powder bowl. Then, the top cover is pressed, and the powder distribution paddle is lowered relative to the support towards the bottom of the powder bowl to uniformly distribute the coffee powder in the powder bowl. Finally, the top cover is rotated to drive the powder distribution paddle to rotate, so as to scatter and distribute the coffee powder in the powder bowl, thereby improving the extraction effect of the coffee. However, when pressing the top cover of the coffee powder distributor, the force must be controlled, which requires certain skills and practice. Moreover, after the operation is completed, the top cover needs to be rotated to drive the powder distribution paddle to rotate, so as to scatter and distribute the coffee powder in the powder bowl, which greatly reduces the convenience of using the coffee powder distributor. To solve the above problems, some related products have been further developed.

[0003] The prior art such as patent CN221383250U proposes an adjustable powder distributor composed of a first adjusting assembly and a second adjusting assembly. The second adjusting assembly is composed of a moving part, a bottom ring, a "T" shaped part, a spring and a nut. The spring is sleeved on the "T" shaped part, the moving part is threadedly connected in the bottom ring, and the moving part is threadedly connected to the outer ring. In the above adjustable powder distributor, the first adjusting assembly and the second adjusting assembly are rotated by holding the inner ring and rotating the moving part. Under the rotation of the two, the rotating end is rotated upward in the annular limiting groove. At the same time, the spring rebounds, which avoids the falling of the rotating end. Through the above operation, the height of the first adjusting assembly and the second adjusting assembly can be adjusted, so as to control the depth of the powder pressing and distributing. At the same time, the "T" shaped part of the above adjustable powder distributor can rotate relative to the powder bowl during pressing the coffee, so that the above adjustable powder distributor can effectively scatter and distribute the coffee in the powder bowl, thereby improving the convenience of using the above adjustable powder distributor.

[0004] However, the user needs to fix the adjusting assembly two at the bowl opening of the powder bowl by hand and rotate the adjusting assembly one along the preset direction to make the adjusting assembly one drive the "T" type piece to rotate relative to the adjusting assembly two and descend towards the bowl bottom of the powder bowl, and at the same time, the adjusting assembly one also descends relative to the adjusting assembly two towards the powder bowl, so that the hand is easily pinched in the use process, which greatly reduces the use safety of the above-mentioned powder distributor. In addition, the adjusting assembly one is subjected to a large friction force during the rotation relative to the adjusting assembly two, which is time-consuming and laborious during use, and greatly reduces the use convenience of the above-mentioned powder distributor.

[0037] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in conjunction with specific embodiments:

[0038] As Figures 1 to 4As shown in the figure, the height adjusting structure 100 of one embodiment is used to be fixedly installed on the coffee powder distributor 10, and includes an adjusting ring 110, a paddle base 120, and a sliding plate 130. An inner peripheral wall of the adjusting ring 110 is formed with a first threaded abutting surface 111. The paddle base 120 is provided with a position avoiding hole 121, and a guide limiting area 122 in communication with the position avoiding hole 121 is further formed at a top end of the paddle base 120. The adjusting ring 110 is sleeved on the top end of the paddle base 120 and is in sliding connection with the paddle base 120. A connecting end of the sliding plate 130 is arranged in the position avoiding hole 121, and the connecting end of the sliding plate 130 is used to be connected with a connecting end of a powder paddle assembly 200. A sliding end of the sliding plate 130 is arranged in the guide limiting area 122 and is in sliding connection with an inner wall of the guide limiting area 122. The sliding end of the sliding plate 130 is formed with a second threaded abutting surface 131 arranged correspondingly to the first threaded abutting surface 111, so that the sliding end of the sliding plate 130 is screwed to the inner peripheral wall of the adjusting ring 110. When it is needed to scatter and distribute the coffee powder in a powder bowl, the coffee powder distributor 10 is first placed at a preset position of the powder bowl, and the position of the paddle base 120 is fixed by hand, and then the adjusting ring 110 is rotated relative to the paddle base 120 along a preset direction, so that the adjusting ring 110 drives the sliding plate 130 to descend along a guide path of the guide limiting area 122 to the bottom of the powder bowl, so as to scatter and distribute the coffee powder in the powder bowl, thereby improving the extraction effect of the coffee powder.

[0039] As shown in the figure, Figures 1 to 4 Further, an outer peripheral wall of the top end of the paddle base 120 is provided with a positioning flange 123, and an annular limiting sliding groove 112 arranged correspondingly to the positioning flange 123 is formed in the inner peripheral wall of the adjusting ring 110, so that the adjusting ring 110 is limited to the top end of the paddle base 120 by the positioning flange 123. Compared with the adjustable powder distributor in the above related art, when the adjusting ring 110 is rotated relative to the paddle base 120, the adjusting ring 110 can be limited to a preset position of the paddle base 120, so that the phenomenon that the adjusting ring 110 slides up and down relative to the paddle base 120 when the coffee powder distributor 10 distributes the coffee powder in the powder bowl is prevented, thereby effectively avoiding the phenomenon that the user is injured by hand when using the coffee powder distributor 10, and greatly improving the use safety of the coffee powder distributor 10 of the present disclosure.
