Description

Technical Field

[0002] In milk tea shops and other retail places, in order to evenly disperse various powders, such as cocoa powder, matcha powder, macchiato powder, etc. on the surface of beverages, the powder sprinkler adopts a scraping component, which includes a scraping piece and a transmission shaft. The scraping piece is fixed on the transmission shaft and rotates on the surface of the powder sprinkling plate. However, this design has a problem, that is, the powder scattering is uneven. Specifically, the position of the powder sprinkling plate close to the transmission shaft will have much less powder distribution than the peripheral position, which leads to the problem of unevenly dispersed powder. This unevenness may be because when the scraping piece rotates, the position close to the transmission shaft has a lower linear velocity. When the scraping piece rotates one week at these positions, less powder is dispersed. The position far from the transmission shaft has a higher linear velocity. When the scraping piece rotates one week at these positions, more materials are dispersed. Therefore, improvement is needed. Summary of the Utility Model

[0029] The following further illustrates the detailed implementation manners of the present utility model with reference to the accompanying drawings.

[0030] It is easy to understand that according to the technical solution of the present utility model, without changing the essential spirit of the present utility model, there are various structural ways and implementation ways that can be mutually replaced by those of ordinary skill in the art. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or as a limitation or restriction on the technical solution of the utility model.

[0031] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined with respect to the structures shown in the respective drawings, and they are relative concepts. Therefore, they may change accordingly according to their different positions and different usage states. So, these or other orientation terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] In some embodiments of the present utility model, for example Figure 1 , the entire powder sprinkler can be hung on a bracket for use, or fixed to other structures for use, including: a container 1 for containing powder materials; a powder sprinkling tray 2 fixed inside or at the bottom of the container 1, and having a plurality of through holes 21 on its surface; a scraping assembly 3 including a scraping member 31 and a transmission shaft 32, the scraping member 31 being fixed on the transmission shaft 32 and rotating on the surface of the powder sprinkling tray 2; a driving device 4 connected to and driving the transmission shaft 32 to rotate; the scraping member 31 includes a first scraping member 311 and a plurality of second scraping members 312, the first scraping member 311 and the second scraping members 312 are arranged around the circumference of the transmission shaft 32, and the length of the first scraping member 311 is at least not equal to that of one of the second scraping members 312.

[0034] Specifically, the powder sprinkler includes a container 1, whose main function is to contain various powder materials, such as cocoa powder, matcha powder, macchiato powder, etc. The container 1 can have different shapes and sizes according to different beverage requirements to accommodate the required powder materials. The powder sprinkling tray 2 is a component fixed inside the container 1, and has a plurality of through holes 21 on its surface. The function of these through holes 21 is to allow the powder materials to pass through. The powder sprinkling tray 2 is usually located at the bottom of the container 1, so that the powder materials can be evenly dispersed on the surface of the beverage. The driving device 4 is a component connected to and driving the transmission shaft 32 to rotate. The function of this driving device 4 is to provide rotational power for the scraping assembly 3, so that the scraping member 31 can effectively perform its function on the surface of the powder sprinkling tray 2. The scraping assembly 3 is the key part of the powder sprinkler, and is composed of two main elements, namely the scraping member 31 and the transmission shaft 32. The scraping member 31 is fixed on the transmission shaft 32 and rotates on the surface of the powder sprinkling tray 2. The main functions of this scraping assembly 3 are as follows: the rotational movement of the scraping member 31 helps to evenly disperse the powder materials on the surface of the beverage, ensuring uniform coverage of the powder materials. When the scraping member 31 rotates on the surface of the powder sprinkling tray 2, its movement mode is equivalent to applying a slight pressure on the surface of the powder materials, slowing down the speed at which the powder particles fly away due to vibration or air flow. The chance of mutual collision between the powder particles is reduced, which reduces the kinetic energy generated by the mutual collision of the powder particles and reduces the chance of the powder particles flying away. This technology enables the powder materials to be more precisely and controllably dispersed onto the target surface, improves the cleanliness of the working environment, improves the comfort of the operator, and also helps to protect the equipment and mechanical parts from the influence of powder material scattering.

[0035] In addition, the rotational movement of the scraping member 31 evenly disperses the powder material onto the surface of the powder spreading tray 2. This disperses the powder particles, enabling them to be more evenly distributed at the channel entrance, reducing aggregation and accumulation between the particles. The rotational movement of the scraping member 31 pushes the powder material through the channel. After the powder material is dispersed on the surface of the powder spreading tray 2, the movement of the scraping member 31 effectively pushes them through the through holes 21 on the powder spreading tray 2. This helps prevent the particles from stagnating or accumulating in the channel. By continuously pushing the powder material towards the outlet of the channel, the space inside the channel is effectively kept open and is not easily blocked by the powder material. Even if some particles may accumulate in the channel, they have the opportunity to be pushed again by the scraping member 31 to continue moving. The rotational movement of the scraping member 31 helps to evenly disperse the powder material and push it through the channel, preventing the problem of powder material blockage in the channel. This movement keeps the channel unobstructed, improves production efficiency, and reduces the need for downtime and cleaning work.

[0036] Among them, the shape of the scraping member 31 can be sheet-like, strip-like, or block-like, etc. The number of scraping members 31 can be one, or multiple ones arranged around the circumference of the transmission shaft 32.

[0037] In a traditional powder spreader, only one scraping member 31 or multiple scraping members 31 with the same length are used to disperse the powder material. This results in a lower linear velocity of the scraping member 31 at the position close to the transmission shaft 32 during rotation, so the dispersion effect is uneven. In this utility model, the length of the first scraping member 311 is not equal to that of the second scraping member 312. This means that when the scraping component 3 rotates, the linear velocities of the first scraping member 311 and the second scraping member 312 are different. This means that during rotation, there are at least two scraping members 31 rotating at the position on the powder spreading tray close to the transmission shaft 32, while there may be only one scraping member 31 rotating on the powder spreading tray at the peripheral position. That is to say, the number of scraping members 31 rotating at the peripheral position on the powder spreading tray is less than the number of scraping members 31 rotating at the position on the powder spreading tray close to the transmission shaft 32. This way of multiple scraping members 31 working together simultaneously helps to disperse more powder material to the position close to the transmission shaft 32 within the same time.

[0038] In some embodiments of this utility model, the scraping member 31 includes a first scraping member 311 and a second scraping member 312, and the length of the first scraping member 311 is less than that of the second scraping member 312.

[0039] Specifically, the material spreading plate is divided into a first material spreading part and a second material spreading part, which are successively located farther away from the transmission shaft 32 and are both in the shape of concentric circles. When the length of the first scraping member 311 is less than that of the second scraping member 312, the first scraping member 311 rotates on the first material spreading part, and there is also a part of the second scraping member 312 close to the transmission shaft 32; on the second material spreading part, there is a part of the second scraping member 312 far from the transmission shaft 32. That is to say, when rotating one week, there are two scraping members 31 rotating on the first material spreading part and one scraping member 31 rotating on the second material spreading part. This makes the material distribution of the first material spreading part greater than that of the second material spreading part, compensating for the problem that the powder distributed in the first powder spreading part is less.

[0040] In some embodiments of the present utility model, the scraping member 31 includes a first scraping member 311, a second scraping member 312 and a third scraping member 313. The length of the first scraping member 311 is less than that of the second scraping member 312, and the length of the second scraping member 312 is less than that of the third scraping member 313.

[0041] Specifically, the material spreading plate is divided into a first material spreading part, a second material spreading part and a third material spreading part, which are successively located farther away from the transmission shaft 32 and are both in the shape of concentric circles. When the length of the first scraping member 311 is less than that of the second scraping member 312 and the length of the second scraping member 312 is less than that of the third scraping member 313, the first scraping member 311 rotates on the first material spreading part, and there is also a part of the second scraping member 312 close to the transmission shaft 32 and a part of the third scraping member 313 close to the transmission shaft 32; on the second material spreading part, there is a part of the second scraping member 312 far from the transmission shaft 32 and a part of the third scraping member 313 far from the transmission shaft 32; on the third material spreading part, there is only a part of the third scraping member 313 farthest from the transmission shaft 32. That is to say, when rotating one week, there are three scraping members 31 rotating on the first material spreading part, two scraping members 31 rotating on the second material spreading part, and only one scraping member 31 rotating on the third material spreading part. This makes the material distribution of the first material spreading part greater than that of the second material spreading part, and the material distribution of the second powder spreading part greater than that of the third material spreading part, compensating for the problem that the powder distributed in the first powder spreading part is less.

[0042] In some embodiments of the present utility model, the scraping member 31 includes a first scraping member 311, a second scraping member 312 and a third scraping member 313. The length of the first scraping member 311 is less than that of the second scraping member 312, and the length of the second scraping member 312 is equal to that of the third scraping member 313.

[0043] In some embodiments of the present utility model, the scraping member 31 includes a first scraping member 311, a second scraping member 312 and a third scraping member 313. The length of the first scraping member 311 is less than that of the second scraping member 312, and the length of the second scraping member 312 is equal to that of the third scraping member 313.

[0044] Specifically, the powder spreading plate is divided into a first powder spreading part, a second powder spreading part, and a third powder spreading part, which are sequentially located farther away from the transmission shaft 32 and are all in the form of concentric circles. When the length of the first scraping part 311 is less than the length of the second scraping part 312, and the length of the second scraping part 312 is equal to the length of the third scraping part 313, the first powder spreading part has the first scraping part 311 rotating, as well as a part of the second scraping part 312 close to the transmission shaft 32 and a part of the third scraping part 313 close to the transmission shaft 32; the second powder spreading part has a part of the second scraping part 312 away from the transmission shaft 32 and a part of the third scraping part 313 away from the transmission shaft 32; the third powder spreading part has only the part of the second scraping part 312 and the third scraping part 313 farthest from the transmission shaft 32. That is to say, when rotating one week, the first powder spreading part has three scraping parts 31 rotating, the second powder spreading part has two scraping parts 31 rotating, and the third powder spreading part also has one scraping part 31 rotating. This makes the powder distribution of the first powder spreading part greater than that of the second powder spreading part, and the powder distribution of the second powder spreading part equal to that of the third powder spreading part, compensating for the problem that the first powder spreading part is allocated less powder.

[0045] In some embodiments of the present invention, when the powder spreading plate 2 is fixed inside the container 1, a wind shielding cavity 5 is formed by the downward extension of the connection between the outer periphery of the container 1 and the powder spreading plate 2.

[0046] Specifically, the container 1 is the main part of the wind shielding cavity 5 and is used to hold the powder. The container 1 can have an appropriate capacity to accommodate the required amount of powder. The wind shielding cavity 5 is usually connected to the container 1, generally integrally formed. The powder spreading plate 2 is located inside the container 1 and at the connection between the container 1 and the wind shielding cavity 5. The surface of the powder spreading plate 2 has a number of through holes 21, which are used to allow the powder to pass through so as to be evenly dispersed on the surface of the beverage. The wind shielding cavity 5 is usually the part where the container 1 extends downward from the outer periphery of the powder spreading plate 2 to cover the powder spreading plate 2, forming a relatively sealed space to prevent the powder from flying. The working principle of the wind shielding cavity 5 is to provide wind resistance during the powder dispersion process to prevent the powder from flying into the environment.

[0047] In some embodiments of the present invention, the powder spreading plate 2 is detachably connected inside or at the bottom of the container 1.

[0048] Specifically, a detachable connection method is usually adopted between the powder sprinkling tray 2 and the container 1, such as threaded connection, snap connection, clamping connection or other connection methods. This ensures that the powder sprinkling tray 2 can be easily connected to the inside of the container 1 and easily disassembled when needed. The detachable connection allows the operator to easily remove the powder sprinkling tray 2 from the container 1, which makes cleaning and maintenance more convenient. Since the powder sprinkler may accumulate powder residues during use and needs to be cleaned frequently, the detachable connection can greatly reduce the maintenance time and workload. The detachable connection also provides flexibility for replacing parts or performing repairs. If the powder sprinkling tray 2 is damaged or needs to be replaced, the operator can easily remove it and replace it with a new part without repairing the entire powder sprinkler. Since the detachable powder sprinkling tray 2 can be easily cleaned, this helps to maintain hygiene and reduce food safety risks. In the food and beverage field, hygiene is very important, and the detachable connection helps to ensure the cleanliness and hygiene of the equipment. The operator can quickly replace or clean the powder sprinkling tray 2, which helps to improve the operation efficiency. There is no need to spend a lot of time on maintenance or replacement of parts, thus reducing the downtime. The detachable connection can reduce the maintenance cost because it reduces the labor and time costs required for part replacement and maintenance. In addition, reducing the downtime of the equipment also helps to reduce the production cost.

[0049] In addition, the detachable connection allows the powder sprinkler to adapt to different types of powders, not just limited to one type, which increases the versatility of the powder sprinkler and makes it more suitable for various beverage preparation requirements. By selecting an appropriately sized powder sprinkling tray 2, the operator can ensure that different powders are evenly dispersed on the surface of the beverage, thereby improving the quality and consistency of the product. Merchants do not have to purchase multiple different types of powder sprinklers, but can replace the powder sprinkling tray 2 on the same device, which can reduce the equipment procurement cost and maintenance cost. The operator can quickly replace the powder sprinkling tray 2 to meet the preparation requirements of different beverages, thereby improving the production efficiency and adaptability.

[0050] In some embodiments of the present utility model, the transmission shaft 32 is rotatably connected to the powder sprinkling tray 2.

[0051] Specifically, the transmission shaft 32 rotates relative to the powder sprinkling tray 2. This configuration enables the scraping member 31 on the scraping assembly 3 on the transmission shaft 32 to rotate on the surface of the powder sprinkling tray 2, thereby achieving the dispersion of the powder. The transmission shaft 32 is a rotating shaft, usually made of a strong material, and it is connected to the driving device 4 to generate rotational power. This rotating transmission shaft 32 is the core part of the powder sprinkler. The powder sprinkling tray 2 is located at the end of the transmission shaft 32 and is kept at a certain distance from the transmission shaft 32, such that the transmission shaft 32 can rotate relative to the powder sprinkling tray 2.

[0052] In some embodiments of the present utility model, an opening 22 or a groove is provided at the center of the powder spreading plate 2, and the transmission shaft 32 is rotatably connected to the powder spreading plate 2 through the opening 22 or the groove.

[0053] Specifically, an opening 22 or a groove is provided in the central region of the powder spreading plate 2, which allows the transmission shaft 32 to pass through and be connected to the powder spreading plate 2. The transmission shaft 32 passes through the opening 22 or the groove at the center of the powder spreading plate 2. This assembly method allows the transmission shaft 32 to be rotatably connected to the powder spreading plate 2. The presence of the opening 22 or the groove ensures a stable connection between the transmission shaft 32 and the powder spreading plate 2, and at the same time enables the operator to easily disassemble them for maintenance or replacement.

[0054] In some embodiments of the present utility model, the container 1 gradually narrows near the opening at the bottom end of the container 1.

[0055] Specifically, the gradually narrowing design is to adapt to the size of the milk tea cup under the container 1 and at the same time be able to accommodate a large amount of powder material. The purpose of this design is to ensure suitability for use with milk tea cups without sacrificing the powder material capacity. This feature can provide better applicability, making the powder sprinkler more versatile and adaptable to milk tea cups of different sizes.

[0056] In some embodiments of the present utility model, a shielding member 6 for preventing the material from falling is provided at the opening of the container 1.

[0057] Specifically, the shielding member 6 is a component located at the opening of the container 1 for preventing the powder material from accidentally falling. The feature of providing the shielding member 6 at the opening of the container 1 has the following working principle and technical effect: It can prevent the powder material from falling out of the container 1 when not needed. This helps to reduce waste and keep the working area clean. The shielding member 6 improves the safety of operation because it avoids the powder material accidentally falling to an inappropriate place, such as the beverage preparation area or the ground.

[0058] In some embodiments of the present utility model, the shielding member 6 includes a fixing frame 61 and a sliding plate 62. The fixing frame 61 is fixedly connected to the opening of the container 1, and the sliding plate 62 is slidably connected to the fixing frame 61.

[0059] Specifically, the fixing frame 61 is a part of the shielding member 6, and it is a structure fixedly installed at the opening of the container 1.

[0060] The sliding plate 62 is another part of the shielding member 6. It is slidably connected to the fixing frame 61, usually achieved through a sliding mechanism. The fixing frame 61 is connected to the opening of the container 1, providing the function of shielding the material from falling. The sliding connection between the sliding plate 62 and the fixing frame 61 means that the sliding plate 62 can slide horizontally relative to the fixing frame 61 to open or close the opening of the container 1, thereby controlling the outflow of the powder material. When the powder sprinkler is needed, the operator can slide the sliding plate 62 to open the opening of the container 1, allowing the powder material to flow out; when not needed, the sliding plate 62 can slide back to its original position to close the opening of the container 1, preventing accidental spillage of the powder material. The design of the shielding member 6 allows the operator to better control the outflow of the powder material, preventing unnecessary waste and spillage of the powder material, and improving the accuracy and safety of the operation.

[0061] In some embodiments of the present utility model, the driving device 4 is fixed to the top of the container 1 and includes a motor and an output shaft. The output shaft is in transmission connection with the transmission shaft 32.

[0062] Specifically, the motor is the core component of the driving device 4, usually an electric motor, which is responsible for providing power to rotate the output shaft. The output shaft is the output part of the motor. It is connected to the rotating shaft of the motor and transmits the rotational power to the transmission shaft 32. The motor generates rotational power, and this power is transmitted through the output shaft to the transmission shaft 32, thereby driving the scraping assembly 3 of the powder sprinkler to rotate. The motor is located at the top of the container 1. The output shaft is connected to the motor through the rotating shaft of the motor and extends to the transmission shaft 32. This movement is transmitted through the output shaft to the transmission shaft 32, and the transmission shaft 32 further drives the scraping member 31 to rotate by connecting to the scraping assembly 3, realizing the dispersion of the powder material.

[0063] Operation steps: Turn on the motor. The motor transmits rotational power to the transmission shaft 32 through the output shaft. The transmission shaft 32 drives the rotation of the scraping member 31 by connecting to the scraping assembly 3, evenly dispersing the powder material onto the surface of the beverage. The introduction of the driving device 4 allows the powder sprinkler to achieve automated powder dispersion operation, improving the convenience and accuracy of the operation, and reducing the need for manual operation at the same time.

[0064] In some embodiments of the present utility model, the material of the container 1 is a transparent material.

[0065] Specifically, the main function of the transparent container 1 is to allow the operator or customer to directly observe the powder level inside the container 1, thereby mastering the usage and remaining amount of the powder material. The method of manufacturing such a transparent container 1 includes selecting and processing a transparent material, usually plastic or glass, to form a specific shape of the container 1. The introduction of the transparent container 1 allows the operator or customer to monitor the powder level in real time, thereby better managing the usage of the powder material, reducing waste, and improving the operation efficiency.

[0066] The utility model is provided with a first scraping member 311 and a plurality of second scraping members 312. When the scraping assembly 3 rotates on the powder spreading plate 2, at least two scraping members 31 rotate at positions close to the transmission shaft 32, so that more powder materials can be evenly dispersed at these positions. In this way, the problem of uneven material distribution between the central position and the peripheral position of the powder spreading plate 2 no longer occurs.

[0067] The above are only the principles and preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, based on the principle of the utility model, several other variations can be made, which should also be regarded as the protection scope of the utility model.
