Description
Technical Field
[0001] This utility model relates to the field of tea powder feeding technology, and in particular to a tea powder feeding mechanism. Background Technology
[0002] A tea-making machine is a device used for automating tea brewing. By integrating functions such as feeding, watering, stirring, and temperature control, it achieves standardized and efficient tea production. It is widely used in commercial tea shops and teahouses, and is also gradually entering home settings.
[0003] However, the feeding mechanism of existing tea-making machines usually uses a method of adding a fixed amount of tea powder directly into the pipe from a tea powder storage tank. This causes clumps or lumps of powder to get stuck in the pipe, with only a small amount of tea powder falling out, affecting the taste of the tea. In severe cases, the clumps or lumps of powder can block the pipe, causing equipment malfunction and preventing normal operation. Utility Model Content
[0004] The purpose of this invention is to propose a tea powder feeding mechanism to solve the problem of the feeding mechanism of existing tea brewing machines, which usually uses a tea powder storage tank to directly add a fixed amount of tea powder into the pipeline for brewing tea. This causes clumps or lumps of powder to get stuck in the pipeline, with only a small amount of tea powder being dispensed, affecting the taste of the brewed tea. In severe cases, the clumps or lumps of powder can also block the pipeline, causing equipment failure and preventing normal operation.
[0005] To achieve this objective, the present invention adopts the following technical solution: A tea powder feeding mechanism includes a housing, a conveying screw, a stirring component, a rear cover, a top cover, a first driving unit, and a second driving unit; The interior of the housing is provided with a stirring zone, a feeding zone, and a discharge port. The stirring zone is connected to the discharge port through the feeding zone. The conveying screw is located in the feeding zone, with one end of the conveying screw located above the discharge port and the other end of the conveying screw connected to the first driving unit. The first driving unit is used to drive the conveying screw to rotate and convey tea powder. The first driving unit is installed on the rear cover, and the rear cover is installed at the rear end of the housing. The top cover is installed on the top of the housing. The top cover is provided with a feeding funnel, which is connected to the stirring zone. The stirring element is located in the stirring zone and between the feeding funnel and the conveying screw. The second drive unit is installed on the top cover. The output end of the second drive unit is connected to the stirring element. The second drive unit is used to drive the stirring element to rotate and disperse the powder.
[0006] Furthermore, the stirring component includes a main shaft and stirring blades. The top end of the main shaft is connected to the output end of the second drive unit. Multiple stirring blades are provided on the outer periphery of the main shaft. Multiple stirring blades in the same layer are evenly spaced along the circumferential direction of the main shaft. Multiple stirring blades in the same column are evenly spaced along the length direction of the main shaft. The stirring blades are inclined.
[0007] Specifically, the top of the housing is provided with a mounting plate, the mounting plate is provided with a positioning hole, the top cover is provided with a positioning post, the positioning post can be placed in the positioning hole, and the end of the positioning post is provided with a first arc surface.
[0008] Preferably, it further includes a locking nut, which is installed on the positioning post, and the top surface of the locking nut can be attached to the bottom surface of the mounting plate.
[0009] In some embodiments, the interior of the housing is provided with a shield and an inclined surface, the shield and the inclined surface are respectively located at the connection between the stirring zone and the feeding zone, the shield is located between the two inclined surfaces, and the shield is directly opposite the discharge port.
[0010] Furthermore, the housing is provided with a first hollow area and a second hollow area, the first hollow area being located above the feeding area, and the two second hollow areas being located on both sides of the feeding area.
[0011] Specifically, a connecting block is provided in the first hollow area, the connecting block is provided with a mounting hole, the back cover is provided with a connecting post, the connecting post can be placed in the mounting hole, and the end of the connecting post is provided with a second arc surface.
[0012] Preferably, the back cover has multiple heat dissipation holes on its left and right sides.
[0013] Compared with the prior art, one of the above technical solutions has the following beneficial effects: Through the coordinated operation of the shell, stirring zone, feeding zone, discharge port, conveying screw, stirring component, rear cover, top cover, feeding funnel, first drive unit, and second drive unit, the tea powder, after entering from the feeding funnel, is directly dispersed by the rotating stirring component during its descent. This effectively solves the problem of tea powder clumping or agglomeration caused by moisture absorption or improper storage, preventing clumped tea powder from clogging the feeding zone or getting stuck in the pitch gap of the conveying screw. This ensures that the tea powder is discharged smoothly without any jamming, reducing the frequency of equipment downtime and maintenance due to blockage. Furthermore, the tea powder, after being dispersed by the stirring component, is in a loose state and can fall more evenly into the feeding zone. Combined with the continuous rotation of the conveying screw, this allows the tea powder to form a stable conveying flow in the feeding zone, preventing clumping that could lead to uneven discharge. This ensures a uniform output of tea powder per unit time, thereby guaranteeing the taste of the tea beverage. Attached Figure Description

Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis. In the description of this utility model, unless otherwise stated, "multiple" means two or more.
[0017] In one embodiment of this utility model, such as Figure 1-6As shown, a tea powder feeding mechanism includes a housing 1, a conveying screw 2, a stirring component 3, a rear cover 4, a top cover 5, a first driving unit 6, and a second driving unit 7. The housing 1 has a stirring zone 11, a feeding zone 12, and a discharge port 13 inside. The stirring zone 11 is connected to the discharge port 13 through the feeding zone 12. The conveying screw 2 is located in the feeding zone 12, with one end positioned above the discharge port 13. The other end of the conveying screw 2 is connected to the first driving unit 6, which drives the conveying screw 2 to rotate and feed tea powder. The powder is disposed of as follows: the first drive unit 6 is installed on the rear cover 4, which is installed at the rear end of the housing 1; the top cover 5 is installed on the top of the housing 1, and the top cover 5 is provided with a feeding funnel 51, which is connected to the stirring zone 11; the stirring element 3 is disposed in the stirring zone 11, and the stirring element 3 is located between the feeding funnel 51 and the conveying screw 2; the second drive unit 7 is installed on the top cover 5, and the output end of the second drive unit 7 is connected to the stirring element 3; the second drive unit 7 is used to drive the stirring element 3 to rotate and disperse the powder.In this embodiment, both the first drive unit 6 and the second drive unit 7 are micro motors. During installation, the first drive unit 6 is installed inside the rear cover 4, and its output end is connected to one end of the conveying screw 2. Then, the rear cover 4 is installed at the rear end of the housing 1, so that the conveying screw 2 is located within the feeding area 12. Further, the second drive unit 7 is installed on the top cover 5, and its output end is connected to the stirring member 3. Then, the top cover 5 is installed on the top of the housing 1, so that the stirring member 3 is located within the stirring area 11. The tea powder feeding mechanism is specifically installed in a tea-making machine, and the first drive unit 6 and the second drive unit 7 are electrically connected to the control system of the tea-making machine. A corresponding tea powder storage tank is provided above the feeding funnel 51. When tea powder needs to be added for brewing tea, the brewing button of the tea-making machine is pressed. The second drive unit 7 drives the stirring member 3 to rotate, and the first drive unit 6 drives the conveying screw 2 to rotate. The tea powder storage tank feeds the tea powder into the stirring area 11 through the feeding funnel 51. A predetermined amount of tea powder is released, entering the stirring zone 11 from the feeding funnel 51. During its descent, the stirring element 3 rotates to disperse the tea powder, preventing clumping. The dispersed tea powder falls into the feeding zone 12, where the conveying screw 2 rotates to transport the tea powder towards the discharge port 13, allowing it to fall into the teacup. This invention, through the coordinated operation of the shell 1, stirring zone 11, feeding zone 12, discharge port 13, conveying screw 2, stirring element 3, rear cover 4, top cover 5, feeding funnel 51, first drive unit 6, and second drive unit 7, ensures that after the tea powder enters from the feeding funnel 51... The tea powder is directly broken up by the rotating agitator 3 during its descent, effectively solving the problem of clumping or agglomeration caused by moisture absorption or improper storage. This prevents clumped tea powder from clogging the feeding area 12 or getting stuck in the pitch gap of the conveying screw 2, ensuring that the tea powder is fed without any jamming throughout the process. This reduces the frequency of equipment downtime and maintenance due to blockage. Furthermore, the tea powder, after being broken up by the agitator 3, is in a loose state and can fall into the feeding area 12 more evenly. Combined with the continuous rotation of the conveying screw 2, this allows the tea powder to form a stable conveying flow within the feeding area 12, preventing the tea powder from clumping and causing uneven feeding. This ensures that the output of tea powder per unit time is uniform and consistent, thereby ensuring the taste of the tea beverage.
[0018] like Figure 2-3As shown, the stirring component 3 includes a main shaft 31 and stirring blades 32. The top end of the main shaft 31 is connected to the output end of the second drive unit 7. Multiple stirring blades 32 are arranged on the outer periphery of the main shaft 31. Multiple stirring blades 32 in the same layer are evenly spaced along the circumference of the main shaft 31, and multiple stirring blades 32 in the same column are evenly spaced along the length of the main shaft 31. The stirring blades 32 are also inclined. In this embodiment, six stirring blades 32 are arranged in the same layer of the main shaft 31, and eight stirring blades 32 are arranged in the same column. The stirring blades 32 arranged in this array can disperse the tea powder, preventing clumping or agglomeration and ensuring the tea powder is loose. Specifically, the stirring blades 32 are inclined, and their cross-section is a parallelogram structure, which not only ensures the quality of dispersion but also prevents tea powder from accumulating on the surface.
[0019] like Figure 1-2 and Figure 3-4 As shown, the top of the housing 1 is provided with a mounting plate 14, the mounting plate 14 is provided with positioning holes 141, and the top cover 5 is provided with positioning posts 52. The positioning posts 52 can be placed in the positioning holes 141, and the end of the positioning post 52 is provided with a first arc surface 521. In this embodiment, there are four positioning holes 141 and four positioning posts 52. The four positioning holes 141 are located at the four corners of the mounting plate 14, and the four positioning posts 52 are located at the four corners of the top cover 5. By positioning and installing the four positioning holes 141 and the four positioning posts 52, the installation accuracy of the top cover 5 can be guaranteed, thereby ensuring that the stirring component 3 is located in the middle of the stirring zone 11, preventing it from deviating and hitting the inner wall of the housing 1. In addition, the end of the positioning post 52 is also provided with a first arc surface 521, which ensures the installation efficiency of the positioning post 52 and avoids jamming during installation.
[0020] like Figure 1-2 As shown, it also includes a locking nut 8, which is installed on the positioning post 52, and the top surface of the locking nut 8 can be attached to the bottom surface of the mounting plate 14. In this embodiment, there are four locking nuts 8. The outer periphery of the positioning post 52 is threaded and adapted to the locking nuts 8. After the positioning post 52 is placed in the positioning hole 141, it is locked and fixed with the locking nuts 8. Specifically, the locking nuts 8 are installed at the end of the positioning post 52, and the top surface of the locking nuts 8 is attached to the bottom surface of the mounting plate 14 to prevent the top cover 5 from vibrating or shaking during operation.
[0021] like Figure 2 and Figure 4As shown, the interior of the housing 1 is provided with a baffle plate 15 and an inclined surface 16. The baffle plate 15 and the inclined surface 16 are respectively located at the connection between the stirring zone 11 and the feeding zone 12. The baffle plate 15 is located between the two inclined surfaces 16 and is directly opposite the discharge port 13. In this embodiment, the baffle plate 15 and the two inclined surfaces 16 are provided at the connection between the stirring zone 11 and the feeding zone 12. The baffle plate 15 is directly opposite the discharge port 13. Specifically, the baffle plate 15 covers the end of the conveying screw 2, thereby preventing the tea powder in the stirring zone 11 from falling directly from the discharge port 13 without being conveyed by the conveying screw 2. The inclined surface 16 facilitates the tea powder to slide down the inner wall to the conveying screw 2, avoiding the accumulation of tea powder.
[0022] like Figure 2 and Figure 5 As shown, the housing 1 has a first hollow area 17 and two hollow areas 18. The first hollow area 17 is located above the feeding area 12, and the two second hollow areas 18 are located on both sides of the feeding area 12. In this embodiment, the first hollow area 17 is specifically located behind the stirring area 11, and is located above the rear half of the feeding area 12. The two second hollow areas 18 are located on the left and right sides of the feeding area 12, and are located below the first hollow area 17. The first hollow area 17 and the two second hollow areas 18 are provided inside the housing 1, thereby reducing the weight of the housing 1 and making it lighter.
[0023] like Figure 5-6 As shown, a connecting block 171 is provided in the first hollow area 17, and the connecting block 171 is provided with a mounting hole 1711. The rear cover 4 is provided with a connecting post 41, which can be placed in the mounting hole 1711, and the end of the connecting post 41 is provided with a second arc surface 411. In this embodiment, there are two connecting blocks 171 and two connecting posts 41. The connecting post 41 and the mounting hole 1711 are interference fit. During installation, the connecting post 41 can be directly pressed into the mounting hole 1711 by external force. The second arc surface 411 at the end of the connecting post 41 prevents jamming during pressing.
[0024] like Figure 5-6 As shown, the rear cover 4 has multiple heat dissipation holes 42 on its left and right sides. In this embodiment, multiple heat dissipation holes 42 are provided on the left and right sides of the rear cover 4, so that the heat generated by the first drive unit 6 can be dissipated to the outside and overheating can be prevented.
