Description

Technical Field

[0001] This utility model relates to the field of beverage equipment technology, specifically to a stirring device and a beverage machine. Background Technology

[0002] In food production, especially in the beverage industry, stirring is a common process that has led to the development of many stirring devices. For example, magnetically driven stirring devices are widely used. These devices typically employ an active magnetic element to drive a driven magnetic element. It should be noted that the driven magnetic element is usually rotatably mounted in a cavity in the center of a mounting base, and the stirring element passes through the mounting base and is connected to the driven magnetic element.

[0003] However, while the active magnetic component rotates to drive the driven magnetic component to rotate, the driven magnetic component moves closer to the active magnetic component under the magnetic attraction of the active magnetic component. Therefore, the driven magnetic component will directly and with a large area abut against the inner wall of the accommodating cavity. As a result, there will be a large friction between the driven magnetic component and the inner wall of the accommodating cavity during the rotation process. This phenomenon will reduce the rotational speed of the driven magnetic component and increase the wear between the driven magnetic component and the mounting base. Utility Model Content

[0004] This invention addresses the shortcomings of existing methods by proposing a stirring device and beverage machine to solve the technical problems of high frictional loss and limited rotational speed in the prior art.

The rolling element is located at least in the receiving cavity and is movably disposed on the side of the second magnetic element close to the first magnetic element.

[0007] The stirring element is connected to the second magnetic element and extends beyond the mounting base;

[0008] The first magnetic element rotates and drives the second magnetic element to rotate via magnetic force, thereby achieving the rotation and stirring of the stirring element. The rolling element serves to isolate the contact friction between the second magnetic element and the accommodating cavity.

[0012] The mounting base is embedded in the second magnetic component. When the first magnetic component attracts the second magnetic component, the ball abuts against the inner wall of the accommodating cavity.

[0013] Optionally, the second magnetic element includes a driven magnet and a rotating base;

[0014] The rotating seat includes a base and a rotating column. The rotating column is disposed on the base and extends through the receiving cavity. The rotating column serves as the rotating shaft on which the base is rotatably disposed of in the mounting seat.

[0015] The driven magnet and the mounting base are embedded in the base, and the stirring element is connected to the rotating column;

[0016] The rolling element is movably disposed on the side of the base near the first magnetic element.

[0017] Optionally, the driven magnet is embedded in the base on the side near the first magnetic element;

[0018] Alternatively, the driven magnet is cross-shaped and embedded in the base on the side near the first magnetic element.

[0019] Optionally, the agitator includes a threaded shaft, agitator blades, and two locking nuts;

[0020] The base is provided with a hidden groove. One end of the threaded shaft passes through the rotating column and enters the hidden groove. Two locking nuts are respectively screwed onto the threaded shaft. One locking nut is located at the end of the rotating column away from the base, and the other locking nut is located in the hidden groove. The two locking nuts move in opposite directions to lock the threaded shaft.

[0021] The stirring blade is located at the other end of the threaded shaft.

[0022] Optionally, the first magnetic component includes a mounting strip, an active magnet, and an active magnet.

[0023] The mounting strip is rotatably mounted on the bracket, and the first active magnet and the second active magnet are each located at one end of the mounting strip.

[0024] Optionally, it further includes a driving member, which is disposed on the bracket and acts on the first magnetic member to drive the first magnetic member to rotate.

[0029] The beneficial technical effects brought about by the technical solution provided by this utility model embodiment include:

[0030] By arranging a rolling element on the side of the second magnetic element close to the first magnetic element, when the first magnetic element attracts the second magnetic element and causes the second magnetic element to move closer to the first magnetic element, the rolling element can isolate the second magnetic element from the inner wall of the accommodating cavity. Thus, when the second magnetic element rotates, the second magnetic element forms rolling friction with the inner wall of the accommodating cavity through the rolling element, thereby reducing the frictional resistance between the second magnetic element and the inner wall of the accommodating cavity, reducing frictional loss, and increasing the rotational speed of the second magnetic element.

[0043] The present invention provides a stirring device and a beverage machine, which aims to solve the above-mentioned technical problems of the prior art.

[0044] The technical solution of this utility model and how the technical solution of this utility model solves the above-mentioned technical problems will be described in detail below with specific embodiments.

[0045] This utility model provides a stirring device product, the structural schematic diagram of which is shown below. Figure 1 or Figure 3 As shown, it includes: a bracket 10, a first magnetic element 20, a mounting base 30, a second magnetic element 40, a rolling element 50, and a stirring element 60; the first magnetic element 20 is rotatably disposed on the bracket 10, with the axis of rotation of the first magnetic element 20 defined as a reference line, the mounting base 30 is aligned and disposed on the reference line, the mounting base 30 is provided with a receiving cavity 31, the second magnetic element 40 is rotatably disposed in the receiving cavity 31 of the mounting base 30, the rolling element 50 is located in the receiving cavity 31, and is at least movably arranged on the side of the second magnetic element 40 close to the first magnetic element 20; the stirring element 60 is connected to the second magnetic element 40 and extends outside the mounting base 30; the first magnetic element 20 rotates and drives the second magnetic element 40 to rotate through magnetic force, thereby achieving the rotation and stirring of the stirring element 60, and the rolling element 50 serves to isolate the contact friction between the second magnetic element 40 and the receiving cavity 31.

[0046] For example, this embodiment is described from above and below. The bracket 10 can be a flat plate or profile frame with a supporting function, etc., which will not be described in detail here. The first magnetic component 20 and the second magnetic component 40 are magnetic components. The mounting base 30 can be divided into a base and a cover. The base has a slot, and the cover covers the slot to form a receiving cavity 31. The mounting base 30 is located directly below the first magnetic component 20 (ideally, the vertical center lines of the two should coincide). The second magnetic component 40 is rotatably disposed in the receiving cavity 31, and the stirring component 60 passes through the bottom of the mounting base 30 and is connected to the second magnetic component 40.

[0047] The key point is that in this embodiment, a rolling element 50 is arranged on the top of the second magnetic component 40, allowing the rolling element 50 to roll freely on top of the second magnetic component 40. According to existing principles, the first magnetic component 20 and the second magnetic component 40 are driven by the principle of attraction between like magnetic poles and repulsion between dissimilar magnetic poles. The first magnetic component 20, as the active driving source, can be rotated manually. However, because both the first and second magnetic components 20 and 40 possess magnetic force, they may attract each other. Without the rolling element 50, the top of the second magnetic component 40 would directly abut against the top wall of the accommodating cavity 31. During rotation, the top of the second magnetic component 40 would experience significant friction (mainly sliding friction) with the top wall of the accommodating cavity 31, easily causing substantial wear. This reduces the rotational speed of the second magnetic component 40, affecting the stirring speed of the stirring component 60. Therefore, after the rolling element 50 is set, the second magnetic element 40 can roll (roll) and rub against the top wall of the accommodating cavity 31 through the rolling element 50. This solution reduces the friction and thus solves the aforementioned problem.

[0048] Furthermore, rolling elements can also be provided on the top or side of the second magnetic element 40, which can also reduce the degree of direct friction and wear between the corresponding side walls and inner walls of the second magnetic element 40 and the accommodating cavity 31.

[0049] For example, in order to avoid magnetic attraction between the second magnetic element 40 and the mounting base 30 and the rolling element 50, the mounting base 30 and the rolling element 50 can be made of non-metallic materials.

[0050] Optionally, combined Figure 2 As shown in the figure, the stirring device product of this utility model includes a rolling element 50 comprising a ball bearing 51.

[0051] Among them, the ball 51 is spherical, which can minimize friction and improve rolling performance; alternatively, the ball 51 can be replaced with a roller, the side of which is used for rolling.

[0052] Optionally, combined Figure 2 As shown, the rolling element 50 also includes an embedding seat 52 and a sealing plate 53; the embedding seat 52 is provided with a placement groove 521, and the ball 51 is rotatably disposed in the placement groove 521; the sealing plate 53 is provided with a through hole 531, and the sealing plate 53 covers the placement groove 521, and the ball 51 partially passes through the through hole 531 to protrude from the side of the sealing plate 53 away from the placement groove 521; the embedding seat 52 is embedded in the second magnetic member 40, and when the first magnetic member 20 attracts the second magnetic member 40 to approach, the ball 51 abuts against the inner wall of the receiving cavity 31.

[0053] For example, the mounting base 52 is a column, and one end of the mounting base 52 is provided with a mounting groove 521. The mounting groove 521 is adapted to the ball 51, but the depth of the mounting groove 521 is greater than the radius of the ball 51 but less than its diameter, and the diameter of the through hole 531 is smaller than the diameter of the ball 51. Therefore, after the sealing plate 53 covers the mounting groove 521, the ball 51 will not detach from the mounting groove 521, but the ball 51 can still roll in the mounting groove 521.

[0054] Furthermore, the second magnetic component 40 may be provided with a cylindrical groove, and the mounting seat 52 is embedded in the cylindrical groove. Note that the ball 51 protrudes from the top wall of the second magnetic component 40. In this embodiment, the ball 51 is directly connected to the second magnetic component 40 through the mounting seat 52. Compared with the aforementioned arrangement of the ball 51, the second magnetic component 40 can be evenly arranged with rolling elements 50 on the same side as needed, achieving a balanced arrangement of rolling support points, thereby ensuring the stable rotation of the second magnetic component 40.

[0055] Furthermore, when the ball bearing 51 is replaced with a roller, the through hole 531 on the sealing plate 53 becomes a square hole. Similarly, the depth of the groove 521 is greater than the radius of the roller but less than its diameter, the diameter of the through hole 531 is less than the diameter of the ball bearing 51, and the length of the square hole is greater than or equal to the length of the roller. In this way, the sealing plate 53 is fitted onto the roller, and the roller can rotate without coming off.

[0056] Optionally, the second magnetic element 40 includes a driven magnet 41 and a rotating seat 42; the rotating seat 42 includes a base 421 and a rotating column 422, the rotating column 422 is disposed on the base 421, the rotating column 422 extends to the outside of the receiving cavity 31, and the rotating column 422 serves as the rotating shaft for the base 421 to be rotatably disposed on the mounting seat 30; the driven magnet 41 and the embedding seat 52 are embedded in the base 421, and the stirring element 60 is connected to the rotating column 422; the rolling element 50 is movably disposed on the side of the base 421 near the first magnetic element 20.

[0057] For example, the base 421 is preferably disc-shaped. The rotating post 422 is disposed at the bottom center of the base 421 to form a T-structure. A rotating through hole is provided at the center of the bottom wall of the receiving cavity 31, and the bottom end of the rotating post 422 extends through the rotating through hole to the outside of the rotating through hole. It should also be noted that when the base 421 and the rotating post 422 move upward until the ball 51 abuts against the top wall of the receiving cavity 31, the rotating post 422 will not disengage from the rotating through hole.

[0058] Optionally, the driven magnet 41 is embedded in the base 421 on the side near the first magnetic member 20; or, the driven magnet 41 is cross-shaped and embedded in the base 421 on the side near the first magnetic member 20.

[0059] For example, the driven magnet 4 is located on the side of the base 421 closest to the first magnetic member 20 (i.e., the top), where it is closer to the first magnetic member 20, resulting in a stronger magnetic drive between them. Furthermore, the driven magnet 41 is embedded in the base 421, simplifying its fixation. Preferably, in this embodiment, the driven magnet 41 is fully embedded in the base 421, and its absence from protruding from the base 421 reduces its impact on the ball bearing 51.

[0060] In addition, the driven magnet 41 is configured in a cross shape, and the corresponding base 421 is provided with a cross-shaped groove for mounting the cross-shaped driven magnet 41. The cross-shaped magnet has more magnetic pole distribution points, which enhances the interaction force between it and the first magnetic element 20.

[0061] Furthermore, within the defined circular base 421, the cross-shaped driven magnet 41 divides the base 421 into four equal parts, and a rolling element 50 can be provided on each part.

[0062] Optional, combined Figure 4 As shown, the stirring component 60 includes a threaded shaft 61, a stirring blade 62, and two locking nuts 63; the base 421 is provided with a hidden groove, one end of the threaded shaft 61 passes through the rotating column 422 and enters the hidden groove, and the two locking nuts 63 are respectively screwed to the threaded shaft 61, one locking nut 63 is located at the end of the rotating column 422 away from the base 421, and the other locking nut 63 is located in the hidden groove. The two locking nuts 63 move spirally towards each other to lock the threaded shaft 61; the stirring blade 62 is provided at the other end of the threaded shaft 61.

[0063] For example, for ease of processing, the hidden groove continues to be machined towards the rotating column 422 from the bottom of the aforementioned cross groove, with the bottom of the hidden groove extending to the end where the rotating column 422 connects to the base 421. As described above, the rotating column 422 is provided with a mounting through hole or a through-hole screw hole; in this embodiment, a screw hole is preferred. The threaded shaft 61 is screwed into the screw hole, with its top end entering the hidden groove and its bottom end protruding from the lower end of the rotating column 422. The two locking nuts 63 move towards each other to lock the threaded shaft 61, and the top locking nut 63 is located in the hidden groove. Of course, the stirring blade 62 is connected to the bottom end of the threaded shaft 61. In particular, the midpoint of the bottom of the stirring blade 62 is provided with an upward-facing concave arc, allowing the material to be stirred to pass through the concave arc during stirring, reducing the stirring resistance of the stirring blade 62 while increasing the disturbance.

[0064] Optionally, the first magnetic component 20 includes a mounting strip 21, an active magnet 22, and an active magnet 23; the mounting strip 21 is rotatably mounted on the bracket 10, and the active magnet 22 and the active magnet 23 are each mounted at one end of the mounting strip 21.

[0065] For example, both the active magnet 22 and the active magnet 23 are circular magnets with better magnetic field uniformity. With the edge of the circular region within the rotation range of the driven magnet 41 as a reference, the vertical projections of the active magnet 22 and the active magnet 23 at least coincide on the circular region; ideally, the vertical projections of the centers of the active magnet 22 and / or the active magnet 23 coincide on the edge of the circular region. This results in a shorter pole distance between the active magnet 22 and the end of the driven magnet 41, enabling better actuation.

[0066] Optionally, it also includes a drive member 70, which is disposed on the bracket 10 and acts on the first magnetic member 20 to drive the first magnetic member 20 to rotate.

[0067] For example, the drive component 70 is a motor, and the output shaft of the motor is connected to the midpoint of the mounting strip 21. The motor drives the mounting strip 21 to rotate. More preferably, to reduce the overall height of the mixing device, the motor is horizontally mounted on the bracket 10, and the output direction of the motor is changed by a reducer or the like, so that the mounting strip 21 is connected to the reducer.

[0068] Based on the same utility model concept, combined with Figure 5 As shown in the figure, the present invention provides a beverage machine (including but not limited to a milk tea machine), which includes: a base 80, a support member 90 and the above-mentioned stirring device; a bracket 10 is disposed on the base 80 and a mounting base 30 is disposed on the support member 90.

[0069] For example, the support member 90 can be various types of brackets, etc., which mainly provide support for the mounting base 30.

[0070] Optionally, the support member 90 includes a material bucket, the mounting base 30 is disposed on the material bucket, and the stirring member 60 extends into the material bucket;

[0071] Alternatively, the support member 90 includes a material bucket and a bucket lid, with the bucket lid covering the material bucket, the mounting base 30 disposed on the bucket lid, and the stirring member 60 passing through the bucket lid and extending into the material bucket.

[0072] For example, the material bucket serves as both a mounting support for the mounting base 30 and a container for the material, thus reducing the amount of material required and simplifying the overall structure of the beverage machine. Additionally, the support member 90 may also include a lid with a through hole for the threaded shaft 61 to pass through, and the lid is sandwiched between the bottom locking nut 63 and the mounting base 30.

[0073] In addition, a square groove is provided on the top of the bucket lid, and the bottom of the mounting base 30 in this embodiment is provided with a step corresponding to the depth of the square groove. The step is engaged with the edge of the square groove, and the mounting base 30 is screwed to the bucket lid by bolts or the like.

[0074] In addition, the bottom of the material barrel is provided with a recessed part that is recessed inward. A discharge pipe that connects to the inside of the material barrel is provided on the outer wall of the recessed part. The discharge pipe is equipped with a discharge switch. The recessed part provides a hidden installation position for the discharge pipe to prevent spatial collision and other problems caused by the protruding part of the discharge pipe.
