Description

Technical Field

[0001] The utility model relates to the technical field of powder dispensing needles, in particular to a rotatable powder dispensing needle. Background Art

[0002] When brewing powdered beverages, such as coffee, in order to avoid over-extraction or under-extraction, which will affect the flavor of the final beverage, we usually use a powder distributor to stir the coffee before extracting it, so that the coffee powder layer is distributed more evenly, so as to release the wonderful flavor of the coffee as much as possible.

[0003] A common type of powder distributor on the market is the needle-type powder distributor, which relies on multiple fine needles to break up coffee powder clumps when in use. Existing needle-type powder distributors are basically divided into two types. One is similar to an ordinary powder distributor or powder hammer, with many needles at the bottom. When in use, it is placed directly on the powder bowl, and then the top is rotated to drive the needles at the bottom to rotate, thereby achieving the powder distribution effect mentioned above; the other type has about three needles on a small handle, which needs to be fiddled with in the powder bowl by yourself, generally called a powder distribution needle. Because of their simple shape and low price; however, the needles in the above two types of needle powder distributors are directly fixed on the handles, which results in a fixed area of ​​powder dispersed after one rotation or one stirring of the needle powder distributors, which is expressed here as loose powder area. The diameters of powder bowls vary, while the loose powder area of ​​existing needle powder distributors is fixed, which results in the existing needle powder distributors being unable to adapt well to powder bowls of different diameters. For example, when the diameter of the powder bowl is large, it takes a longer time to evenly stir the coffee in the powder bowl using a needle powder distributor with a smaller loose powder area, which is time-consuming and laborious.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 5 and attached Figure 6The utility model embodiment discloses a rotatable powder dispensing needle, including a mounting member 1, an adjusting member 2, a plurality of needle bodies 3, and a locking assembly 4. The mounting member 1 is provided with a plurality of first holes 5, and the first holes 5 are through holes; the adjusting member 2 is rotatably connected to the mounting member 1, and the adjusting member 2 is provided with a plurality of second holes 6, and the plurality of second holes 6 correspond to the plurality of first holes 5 one by one; the needle body 3 is composed of a needle head 31 and a pin 32, and the needle head 31 and the pin 32 are both rod-shaped, and the needle head 31 is used for stirring powder, and the needle head 31 is sleeved in the second hole 6, and the pin 32 is sleeved in the first hole 5, and the lateral size of the needle head 31 is larger than the lateral size of the first hole 5. By rotating the mounting member 1 and the adjusting member 2 relative to each other, the first hole 5 and the corresponding second hole 6 can be relatively moved to drive the needle body 3 to tilt, so that the plurality of needle bodies 3 expand or contract, thereby adjusting the powder dispensing area of ​​the plurality of needle bodies 3; the locking assembly 4 is connected to the mounting member 1, and is used to fix the relative positions of the mounting member 1, the adjusting member 2 and the plurality of needle bodies 3.

[0040] In actual use, taking coffee powder distribution as an example, the powder distribution area of ​​multiple needle bodies 3 is adjusted according to the size of the inner diameter of the powder bowl. During the specific adjustment, first release the locking and fixing of the locking component 4 on the mounting part 1, the adjusting component 2 and the multiple needle bodies 3, and then rotate the mounting part 1 and the adjusting component 2 relatively to make the first hole 5 and the corresponding second hole 6 move relative to each other. Since the needle head 31 is located in the second hole 6 and the pin 32 is located in the first hole 5, therefore, according to the principle that two points determine a line, during the relative movement of the first hole 5 and the corresponding second hole 6, the needle head 31 will also continue to tilt, and the pin 32 will be driven to tilt, so that the multiple needle bodies 3 expand or contract, thereby achieving the purpose of adjusting the powder distribution area. After the adjustment is completed, the relative positions of the mounting part 1, the adjusting component 2 and the multiple needle bodies 3 are fixed by the locking component 4, and then it can be used, which can better adapt to powder bowls of different diameters, making the powder distribution process more time-saving and labor-saving; in general, by using the rotatable powder distribution needle, the powder distribution area of ​​the powder can be adjusted.

[0041] It should be noted that the “lateral dimension” mentioned in the present application refers to the dimension of the smallest cross section on an object. For example, when the needle 31, the pin 32, the first hole 5, and the second hole 6 are all rotating bodies and are cylindrical, the lateral dimension of the needle 31 is the dimension of the surface perpendicular to the axis of the needle 31, the lateral dimension of the pin 32 is the dimension of the surface perpendicular to the axis of the pin 32, the lateral dimension of the first hole 5 is the dimension of the surface perpendicular to the axis of the first hole 5, and the lateral dimension of the second hole 6 is the dimension of the surface perpendicular to the axis of the second hole 6.

[0042] It should be noted that the present application does not limit the length, shape and other geometric parameters of the needle body 3, the first hole 5 and the second hole 6, which can be flexibly selected according to actual needs. By changing these geometric parameters, the adjustment range of the powder dispersion area of ​​multiple needle bodies 3 can be changed; for example, when the needle head 31, the pin 32, the first hole 5 and the second hole 6 are all rotating bodies and are cylindrical, increasing the aperture of the first hole 5, increasing the aperture of the second hole 6, reducing the hole depth of the first hole 5, reducing the hole depth of the second hole 6, reducing the spacing between the first hole 5 and the second hole 6 when they are coaxial, reducing the diameter of the needle head 31, and reducing the diameter of the pin 32 can all expand the inclination range of the needle body 3, that is, expand the The adjustment range of the loose powder area; on the contrary, when the needle 31, the pin 32, the first hole 5, and the second hole 6 are all rotating bodies and are cylindrical, reducing the aperture of the first hole 5, reducing the aperture of the second hole 6, increasing the hole depth of the first hole 5, increasing the hole depth of the second hole 6, increasing the spacing between the first hole 5 and the second hole 6 when they are coaxial, increasing the diameter of the needle 31, and increasing the diameter of the pin 32 can all reduce the inclination range of the needle body 3, that is, reduce the adjustment range of the loose powder area of ​​multiple needle bodies 3; when understanding the above-mentioned adjustment range, it can be analyzed by analogy to a right triangle, and the angle range is changed by changing the side length. Since its adjustment principle is a prior art and the structure is relatively simple, it will not be repeated here.

[0043] It should be noted that the specific structure and method of the rotational connection between the mounting member 1 and the adjusting member 2 are not limited in the present application, and can be flexibly designed according to actual needs. For example, it can be set as a rotational connection structure with a non-detachable connection similar to a bearing, or it can be set as a rotational connection structure with a detachable connection.

[0044] It should be noted that the specific shapes of the mounting member 1 , the adjusting member 2 and the rotating member 41 are not limited in the present application and can be flexibly selected according to actual needs.

[0045] Furthermore, since the needle body 3 is thinner, longer and lighter, it is easy to tip over when the needle body 3 is placed as the bottom of the rotatable powder distribution needle; and if the rotating part 41 is placed as the bottom of the rotatable powder distribution needle, the thin and long needle body 3 is vertically upward, and the user may be easily pricked when taking it. In order to solve the above problems, the following settings are made in this embodiment. Specifically, it also includes a base 15, and a placement groove 16 that runs through the base 15 and is vertically arranged, and the pin 32 on the rotatable powder distribution needle can be inserted into the placement groove 16.

[0046] Through the design of the above structure, the rotatable powder distribution needle can be easy to place, not easy to tip over, and safer to take. In addition, since the pin 32 is located in the placement groove 16, it can also prevent the pin 32 from being directly exposed to the air, causing the pin 32 to be contaminated by dust.

[0047] It should be noted that the base 15 should be heavy to ensure that the center of gravity of the whole formed by the rotatable powder dispensing needle placed on the base 15 is located at the bottom, so as to maintain stability and not easily tip over.

[0048] Based on the above scheme, the following design can also be adopted. Specifically, the adjusting member 2 is arranged to be basically truncated cone-shaped, with one end with a smaller area close to the mounting member 1, and the other end with a relatively larger area close to the rotating member 41. The mounting member 1 and the placement groove 16 are basically cylindrical, and the diameter of the mounting member 1 is smaller than the diameter of the placement groove 16. The diameter of the end with a larger area of ​​the adjusting member 2 is larger than the diameter of the placement groove 16, so that the rotatable powder distribution needle can be partially inserted into the interior of the placement groove 16, and the other part is located outside the placement groove 16 for easy taking.

[0049] See attached Figure 3 -Attached Figure 6 In order to more clearly describe how the mounting member 1 and the adjusting member 2 rotate, one of the rotating structures is introduced in this embodiment. Specifically, the mounting member 1 and the adjusting member 2 are detachably connected, a slider 7 is provided at one end of the mounting member 1 close to the adjusting member 2, and a slide groove 8 is provided at one end of the adjusting member 2 close to the mounting member 1. The outer surface of the slider 7 and the inner surface of the slide groove 8 are both cylindrical and slidably connected.

[0050] Furthermore, the following design is also carried out in this embodiment. Specifically, a connecting hole 9 connecting the slide groove 8 and the plurality of second holes 6 is further provided on the adjusting member 2 .

[0051] By designing the above structure, the hole depth of the first hole 5 can be reduced, thereby increasing the range of the inclination angle of the pin 32 .

[0052] See attached Figure 3 In order to achieve the purpose of uniform powder distribution more quickly, the following design is carried out in this embodiment. Specifically, the mounting member 1 and the adjusting member 2 are both rotating bodies. There are six first holes 5 arranged in a circular array on the mounting member 1, and there are six second holes 6 arranged in a circular array on the adjusting member 2.

[0053] Through the design of the above structure, since the first holes 5 are evenly distributed on the mounting member 1 and the corresponding second holes 6 are evenly distributed on the adjusting member 2, the multiple needle bodies 3 are also evenly distributed, and the spacing between two adjacent needle bodies 3 is equal. The angle direction and range size of the multiple needle bodies 3 when moving are basically the same. The multiple stirring areas formed after the multiple needle bodies 3 are stirred are evenly distributed, so that the powder layer can reach a uniform state more quickly.

[0054] Furthermore, the following design is also carried out in this embodiment. Specifically, the diameter of the ring formed by the six first holes 5 is the same as the diameter of the ring formed by the six second holes 6, so that the first holes 5 and the corresponding second holes 6 can be coaxial.

[0055] Through the design of the above structure, when the first hole 5 and the corresponding second hole 6 are coaxial, the multiple needles 31 are parallel to each other, and the extension direction of the needles 31 is consistent with the axial direction of the adjusting member 2. At this time, the powder dispersion area of ​​the multiple needle bodies 3 is the smallest. In this state, relative to the mounting member 1, whether the adjusting member 2 is rotated forward or reversed, the powder dispersion area of ​​the multiple needle bodies 3 will be expanded; it should be noted that the forward rotation can be clockwise or counterclockwise, and the reverse rotation direction is opposite to the forward rotation direction.

[0056] Based on the above scheme, a specific description is given about "when the first hole 5 and the corresponding second hole 6 are coaxial, relative to the mounting member 1, whether the adjusting member 2 is rotated forward or reversed, the powder dispersion area of ​​the multiple needle bodies 3 will be expanded". Taking the extension direction of the needle head 31 and the pin 32 being the same as an example, when the first hole 5 and the corresponding second hole 6 are coaxial, the two adjacent needle bodies 3 are parallel to each other. After the adjusting member 2 is rotated forward or reversed relative to the mounting member 1, since the spacing between the two adjacent first holes 5 remains unchanged, the spacing between the two adjacent second holes 6 remains unchanged. Therefore, the two adjacent needle bodies 3 are equivalent to crossing at the first hole 5 on the mounting member 1, and the position of the intersection remains unchanged. This makes it possible that when the first hole 5 and the corresponding second hole 6 are coaxial, continuous forward rotation or continuous reverse rotation of the adjusting member 2 can make the spacing between the ends of the two adjacent pins 32 away from the needle head 31 larger and larger, thereby expanding the powder dispersion area of ​​the multiple needle bodies 3; it should be noted that since the needle head 31 will be driven to tilt when the adjusting member 2 rotates, the range of the rotation angle of the adjusting member 2 is limited, and it is impossible to infinitely expand the powder dispersion area of ​​the multiple needle bodies 3.

[0057] The specific material of the needle body 31 is not limited in the present application, and can be flexibly selected according to actual needs, such as a rigid material or a flexible material. In order to ensure that the needle body 31 does not affect the safety of the coffee powder during the stirring process, the following design is carried out in this embodiment. Specifically, the material of the needle head 31 and the pin 32 are both 304 stainless steel.

[0058] Through the design of the above structure, the needle body 3 can directly contact the food without affecting the safety of the food. In addition, since 304 stainless steel is selected as the material for manufacturing the needle body 3, the needle body 3 has the advantages of not being prone to permanent deformation, not being prone to breakage, being easy to clean, and having a longer service life during use.

[0059] Furthermore, when the needle 31 is made of a rigid material and is not deformable, the needle 31 and the second hole 6 should be movably connected, and the lateral dimension of the second hole 6 should be larger than the lateral dimension of the needle 31, so that the needle 31 can be tilted with the relative rotation of the mounting member 1 and the adjusting member 2; when the needle 31 is made of a flexible material or a rigid material with high toughness and is deformable, the needle 313 can be movably connected to the second hole 6, or the needle 31 can be fixed at the second hole 6 on the adjusting member 2 without affecting the tilt of the needle 31.

[0060] See attached Figure 2 and attached Figure 7 When the mounting member 1 and the adjusting member 2 rotate relative to each other, the needle 31 will tilt accordingly. Generally, the higher the hardness, the worse the plasticity, and the easier it is to break when subjected to greater force. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, the needle 31 is deformable and basically spring-shaped, so that the needle 31 can be deformed.

[0061] Through the design of the above structure, under the condition of the same material and force, the spring-shaped needle 31 is less likely to break than the straight rod-shaped needle 31; in addition, since the needle 31 in this embodiment is deformable, its ability to resist breakage can be further enhanced.

[0062] See attached Figure 2 , Attachment Figure 4 and attached Figure 5 In the case where the mounting member 1 and the adjusting member 2 are detachably connected, the needle body 3 can obviously also be detachable. However, since the lateral dimension of the needle body 3, especially the lateral dimension of the pin 32 is significantly smaller, the needle body 3 is not easy to insert into the first hole 5. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, the first hole 5 is a conical hole, and the size of the first hole 5 at one end close to the adjusting member 2 is larger than the size of the first hole 5 at one end away from the adjusting member 2.

[0063] Through the design of the above structure, the pin 32 can be guided and assisted to be inserted into the first hole 5, and the range of the inclination angle of the needle body 3 can be increased.

[0064] The specific structure of the second hole 6 is not limited in the present application and can be selected according to actual needs. In the present embodiment, two structures of the second hole 6 are provided. Specifically, the second hole 6 is a through hole or a blind hole.

[0065] See attached Figure 2 , Attachment Figure 5 and attached Figure 8There are various structures that can be locked and fixed, and one of them is introduced in this embodiment. Specifically, a fixing seat 10 is provided at one end of the mounting member 1 close to the adjusting member 2, and a threaded hole 11 is provided in the fixing seat 10. The adjusting member 2 is provided with a through hole 12 corresponding to the fixing seat 10. The locking assembly 4 includes a rotating member 41, a connecting rod 42, and a stud 43. The rotating member 41 is a rotating body, and the rotating member 41 is located on the side of the adjusting member 2 away from the mounting member 1; the connecting rod 42 is sleeved in the through hole 12 and one end is connected to the rotating member 41; the stud 43 engages with the threaded hole 11 and one end is fixedly connected to the connecting rod 42, the sum of the length of the stud 43 and the length of the connecting rod 42 is less than the length of the adjusting member 2, and the sum of the length of the stud 43, the length of the connecting rod 42 and the length of the threaded hole 11 is greater than the length of the adjusting member 2.

[0066] By means of the above structural design, the rotating member 41 can be rotated to clamp and fix the adjusting member 2 between the rotating member 41 and the mounting member 1 , or the clamping and fixing of the adjusting member 2 by the rotating member 41 and the mounting member 1 can be released.

[0067] In order to enrich the functions of the rotatable powder dispensing needle, the following design is carried out in this embodiment. Specifically, a magnetic member 13 is installed on the rotating member 41 .

[0068] Through the design of the above structure, the rotatable powder dispensing needle can be adsorbed and fixed on a metal object for easy storage.

[0069] See attached Figure 1 -Attached Figure 4 Based on the above scheme, the mounting member 1, the adjusting member 2 and the rotating member 41 all need to rotate or rotate relative to each other. In order to prevent slipping, the following design is carried out in this embodiment. Specifically, anti-slip grooves 14 are provided on the mounting member 1 and the rotating member 41.

[0070] Through the design of the above structure, the friction force of the gripping part can be increased to effectively prevent slipping.

[0071] Furthermore, anti-slip grooves can be provided on the adjusting member 2, and the anti-slip grooves 14 on the mounting member 1, the anti-slip grooves 14 on the adjusting member 2, and the anti-slip grooves 14 on the rotating member 41 can be provided with different types, so that different parts can be distinguished more conveniently and quickly, thereby accurately grasping the designated parts.
