Description

Technical Field

[0001] This utility model relates to the field of coffee grinder technology, and in particular to an automatic coffee grinder with built-in weighing. Background Technology

[0002] A coffee grinder is a common device for grinding coffee beans into coffee powder. It mainly grinds coffee beans into coffee powder by the relative rotation between two internal blades.

[0003] Currently, coffee grinders on the consumer market generally use a dispensing unit to measure the amount of coffee grounds. This unit divides the coffee into several spaced-out sections, each section representing the smallest unit of measurement. Each dispensing cycle dispenses one section of coffee, requiring a multiple of this minimum unit. This method cannot meet the requirement of dispensing non-integer multiples of coffee. Furthermore, due to variations in grind size, the average density of the same volume of coffee grounds can differ, leading to significant errors. To address this issue, a precision coffee grinder (CN2024213414199) has emerged on the consumer market. This grinder includes a housing and a dispensing assembly. The housing contains a grinding chamber at its top, and a motor is located inside. A blade is mounted on the motor's output shaft within the grinding chamber. The dispensing assembly is connected to the grinding chamber. The grinder also includes a quantitative weighing assembly, comprising a power board, a control board, an AD converter board, and a weight sensor, etc. This coffee grinder uses a weight sensor to detect the weight of the coffee grounds in the container. When the weight reaches a predetermined value, the motor stops and the weight of the coffee grounds is displayed. Grinding ends when the weight is within acceptable tolerances, thus improving the accuracy of coffee grounds dispensing. However, the part of the weight sensor connected to the stand is exposed to the outside of the grinder, making it susceptible to scratches, impacts, liquid spills, and dust intrusion during daily use, which can affect the lifespan of the weight sensor. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art. Therefore, the objective of this invention is to provide an automatic coffee grinder with a built-in weighing system that can completely control the weight sensor, protecting it and extending its service life.

[0005] To achieve the above objectives, this utility model proposes: An automatic coffee grinder with built-in weighing function, comprising: Organism; A powder outlet pipe is disposed in the machine body; A bracket, which is mounted on the machine body; The powder receiving cup is detachably mounted on the bracket; and A quantitative weighing component, wherein the quantitative weighing component is disposed in the machine body, and the quantitative weighing component includes a weight sensor; The machine body is equipped with a sensor bracket, and the bracket is provided with a mounting cavity. One part of the weight sensor is located inside the machine body and fixed on the sensor bracket, while the other part of the weight sensor extends out of the machine body and is fixed in the mounting cavity.

[0006] Furthermore, a powder-blocking component is provided on the machine body, the powder-blocking component is located between the machine body and the bracket, and the weight sensor passes through the powder-blocking component and is fixed in the mounting cavity.

[0007] Furthermore, the powder-blocking component is provided with a powder-blocking part, which is located above the weight sensor.

[0008] Furthermore, the top surface of the powder-blocking component and the top surface of the powder-blocking part are inclined structures.

[0009] Furthermore, the sensor bracket is provided with a mounting part, and the weight sensor is fixed in the mounting part.

[0010] Furthermore, the bracket is provided with an adjustable component, which includes a support column, an upper slider, and a locking member.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

[0021] like Figure 1-5 As shown, an automatic coffee grinder with built-in weighing includes a body 1, a powder outlet tube 2, a bracket 3, and a powder collection cup 4. The powder outlet tube 2 is located within the body 1, the bracket 3 is mounted on the body 1 and positioned below the powder outlet tube 2, and the powder collection cup 4 is detachably mounted on the bracket 3. When the powder collection cup 4 is placed on the bracket 3, it faces the powder outlet of the powder outlet tube 2, thus catching the coffee powder falling from the powder outlet tube 2.

[0022] It should be noted that the machine body 1 is equipped with a PCB board, a drive motor, a grinding tool assembly and a grinding chamber, and the powder outlet pipe 2 is connected to the grinding chamber. The drive motor, the grinding tool assembly and the grinding chamber are all existing technologies, so they will not be described in detail in this application.

[0023] An automatic coffee grinder with built-in weighing includes a quantitative weighing component housed in the machine body 1. The quantitative weighing component includes a weight sensor 5, a power board, a control board, and an AD conversion board. The quantitative weighing component is existing technology, and for details, please refer to the patent document with patent number CN2024213414199. Therefore, it will not be described in detail in this application. The quantitative weighing component detects the weight of coffee powder in the powder receiving cup 4. When the weight reaches a predetermined value, the motor stops working and displays the weight of the coffee powder. When the weight is within the allowable error range, the grinding ends. This can improve the accuracy of coffee powder metering.

[0024] To prevent the weight sensor 5 from being damaged by scratches, impacts, liquid splashes, or dust intrusion during daily use, this application includes a sensor bracket 6 inside the housing 1 and a mounting cavity 301 on the bracket 3. Part of the weight sensor 5 is located inside the housing 1 and fixed to the sensor bracket 6 with screws, while the other part of the weight sensor 5 protrudes from the housing 1 and is fixed to the mounting cavity 301 with screws. In this way, the weight sensor 5 can be concealed by the housing 1 and bracket 3, preventing it from being exposed to the environment. The weight sensor 5 is encapsulated inside the housing 1 and bracket 3, protected by them, thus avoiding the risks of scratches, impacts, liquid splashes, and dust intrusion during daily use, resulting in a longer lifespan.

[0025] In this embodiment, the weight sensor 5 is a sensor with a maximum range of 5kg, that is, the maximum range of the weight sensor 5 is 5kg.

[0026] Because there is a gap between the machine body 1 and the bracket 3, a very small amount of coffee powder may float outside when the powder outlet tube 2 dispenses coffee powder. This coffee powder may enter the weight sensor 5 through the gap between the machine body 1 and the bracket 3 and then adhere to the weight sensor 5, affecting the accuracy of the weight sensor 5. Therefore, this application provides a powder blocking component 7 on the machine body 1. The powder blocking component 7 is located between the machine body 1 and the bracket 3, and the weight sensor 5 passes through the powder blocking component 7 and is fixed in the mounting cavity 301. In this way, the powder blocking component 7 and the powder blocking part 701 can block the floating coffee powder, preventing the powder blocking component 7 from falling into the weight sensor 5 through the gap between the machine body 1 and the bracket 3, and avoiding the floating coffee powder affecting the accuracy of the weight sensor 5.

[0027] The powder blocking component 7 is provided with a powder blocking part 701, which is a baffle strip arranged along the width direction of the powder blocking component 7. The powder blocking part 701 is located above the weight sensor 5 and can block the gap between the machine body 1 and the bracket 3, thereby preventing the floating coffee powder from falling onto the weight sensor 5 and ensuring the accuracy of the weight sensor 5.

[0028] The top surface of the powder blocking component 7 and the top surface of the powder blocking part 701 are inclined structures, and both are inclined from the upper right to the lower left. The inclined structure plays a guiding role, which can guide the coffee powder falling on the powder blocking component 7 and the powder blocking part 701 to the tray 3 or the table, and avoid excessive coffee powder on the powder blocking component 7 and the powder blocking part 701.

[0029] The sensor bracket 6 is provided with a mounting part 601, which is a groove. The weight sensor 5 is fixed in the mounting part 601 by screws, thereby restricting the position of the weight sensor 5.

[0030] The bracket 3 is equipped with an adjustable component, which includes two support pillars 302, an upper slider 303, and two locking members 304. The two support pillars 302 are symmetrically fixed to the bracket 3. The upper slider 303 is disposed in the support pillars 302 and can move on the support pillars 302. The locking members 304 are disposed in the upper slider 303 and can abut against the support pillars 302. The powder receiving cup 4 is placed on the bracket 3, and its upper end contacts the upper slider 303 and is limited by the upper slider 303. By contacting the locking members 304 to restrict the support pillars 302 and the upper slider 303, the position of the upper slider 303 on the support pillars 302 can be adjusted, thereby changing the height of the upper slider 303 to accommodate different powder receiving cups 4.

[0031] In this embodiment, the locking member 304 is a knurled bolt. The upper slider 303 is provided with bolt holes, and the knurled bolt can be screwed into the bolt holes. The knurled bolt is used in the forward direction so that the end of the knurled bolt abuts against the column, thereby fixing the support column 302 and the upper slider 303. The knurled bolt is used in the reverse direction so that the end of the knurled bolt no longer abuts against the column, thereby fixing the support column 302 and the upper slider 303. After both locking members 304 are in contact with the restriction, the upper slider 303 can move on the column and adjust its height.

[0032] The bracket 3 is provided with two through holes 305, and the support column 302 is provided with an insertion part 306. The insertion part 306 is inserted into the through hole 305 and is adapted to the diameter of the through hole 305. The diameter of the insertion part 306 is smaller than the diameter of the support column 302. Since the diameter of the insertion part 306 is smaller than the diameter of the support column 302, the support column 302 can be inserted and fixed on the bracket 3.

[0033] The sensor bracket 6 is provided with two first connection holes 602, which are threaded holes. The powder blocking component 7 is provided with two second connection holes 702, which are ordinary through holes. The second connection holes 702 are aligned with the first connection holes 602. Screws can be installed in the first connection holes 602 and the second connection holes 702. The screws pass through the second connection holes 702 and are screwed into the first connection holes 602. That is, the sensor bracket 6 and the powder blocking component 7 are connected by screws. The sensor bracket 6 is fixed on the inner wall of the machine body 1, and the powder blocking component 7 is fixed on the outer wall of the machine body 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
