Description

Technical Field

[0001] This utility model relates to a coffee grinder, and more particularly to a device for shaking off residual coffee powder inside the coffee grinder's powder tube. Background Technology

[0002] Coffee is a popular beverage in daily life, and coffee grinders, also known as coffee grinders, grind coffee into powder and dispense it through the outlet. However, due to static electricity generated during grinding and the fineness of the coffee powder particles, some coffee powder adheres to the inner wall of the outlet. In some outlets designed to prevent or reduce powder spillage, the adhering coffee powder is even more prone to forming residue. This residue accumulates after each grind, leading to waste, reduced output, and a mixture of fresh and residual powder that affects taste. Furthermore, it can promote bacterial growth and pose health risks.

[0003] Patent No. ZL202321254523.X, published on November 3, 2023, discloses an easy-to-clean and adjustable coffee grinder core, including a grinding chamber, a motor unit, a lower blade assembly, an upper blade assembly, and an adjusting plate. The grinding chamber is located above the motor unit, the lower blade assembly is installed on the motor output end and located in the grinding chamber, and a powder outlet channel communicating with the grinding chamber is provided at the grinding chamber. The adjusting plate is installed on the grinding chamber and can move up and down, and has a grinding nozzle. The upper blade assembly is detachably installed on the adjusting plate, located in the grinding chamber and above the lower blade assembly, and the upper blade assembly cooperates with the lower blade assembly to grind the material. It has the advantages of being fixed with easy-to-disassemble fasteners after the adjusting plate, upper blade, and upper blade seat are connected, allowing for quick assembly during routine cleaning without removing the entire adjusting plate, avoiding damage caused by frequent disassembly due to fine adjustment threads, and maintaining consistent coarseness adjustment after each disassembly, as well as being quick and easy to operate. However, although this solution allows for quick loading and unloading for cleaning, it cannot be used immediately after each quick cleaning process for grinding coffee beans. This is undoubtedly insufficient to meet the daily operational needs of coffee shop grinders. Utility Model Content

[0004] This invention addresses the shortcomings of existing coffee grinders, such as the tendency for residual coffee powder to form inside the powder outlet tube. This leads to waste, reduced output, and the mixing of fresh and residual powder, affecting taste and potentially causing bacterial growth and health risks. The invention provides a residual powder dislodging device that prevents coffee powder from forming inside or on the inner wall of the powder outlet tube during the grinding process, thus avoiding waste, improving coffee purity, and preventing bacterial growth.

[0005] The specific technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a residual powder shaking device in the powder outlet pipe of a coffee grinder, including a powder outlet seat and a powder outlet pipe, characterized in that: it also includes a powder outlet support, an elastic tube and several elastic tube springs, the powder outlet support is provided with an elastic tube mounting post and an upper powder outlet pipe, the upper powder outlet pipe is connected to the powder outlet seat, the elastic tube and several elastic tube springs are connected to the elastic tube mounting post by washer screws or washer bolts, the elastic tube is provided with a powder outlet pipe connecting pipe, the powder outlet pipe connecting pipe is connected to the upper powder outlet pipe, and the powder outlet pipe and the powder outlet pipe connecting pipe are threadedly connected. This system utilizes the interplay of elasticity between the elastic tube mounting post, the elastic tube itself, and several elastic tube springs to provide synchronized elastic vibration to the powder outlet tube connected to the powder outlet tube. This vibrates away any residual coffee powder that may be present inside the powder outlet tube, preventing powder buildup during the grinding process and avoiding waste. This also improves the purity of the coffee's flavor and prevents bacterial growth. Furthermore, because the elastic tube is connected to the mounting post on the powder outlet support, the vibration also affects the upper powder outlet tube and the connecting tube, effectively achieving automatic elastic vibration powder removal from these tubes. This elastic vibration powder removal is more thorough and cleaner.

[0006] Preferably, the elastic tube mounting post is located on the outer periphery of the upper powder outlet pipe. The lower section of the elastic tube mounting post has an internal thread for threaded connection of the washer screw. The outer circumference of the upper powder outlet pipe is smaller than the inner circumference of the powder outlet pipe connecting pipe. After the elastic tube is installed on the elastic tube mounting post, the upper powder outlet pipe extends into the powder outlet pipe connecting pipe. This improves the stability, reliability, and effectiveness of the elastic vibration installation and connection limiting of the elastic tube, and enhances the reliability and effectiveness of the powder outlet connection of the elastic tube.

[0007] Preferably, the elastic tube includes an elastic tube connector and a powder outlet connector. The powder outlet connector is connected to the elastic tube connector and faces the powder outlet pipe. The elastic tube connector on the outer side of the upper end of the powder outlet connector has a mounting hole or mounting limit groove that mates with the elastic tube mounting post. The upper end of the powder outlet connector has an external threaded connection section. This improves the stability, reliability, and effectiveness of the elastic vibration mounting connection limit of the elastic tube, and also improves the stability, reliability, and effectiveness of the powder outlet connection of the elastic tube.

[0008] Preferably, the outer periphery of the powder outlet pipe connecting pipe is provided with several elastic tube springs. The upper ends of the elastic tube springs abut against the mounting connection holes or mounting connection limiting grooves, and the lower ends of the elastic tube springs are positioned and connected to the elastic tube mounting posts through washer screws. The elastic tube springs are evenly distributed in two, three, or four springs on the outer periphery of the powder outlet pipe connecting pipe and the upper section of the powder outlet pipe. The elastic tube mounting post passes through the mounting connection hole or mounting connection limiting groove, extends into the inner ring of the corresponding elastic tube spring, and is threadedly connected to the washer screw or washer bolt. This improves the stability, reliability, and effectiveness of the elastic vibration installation connection limiting of the elastic tubes, and improves the stability, reliability, and effectiveness of the same-frequency elastic vibration for removing residual powder from the powder outlet pipe.

[0009] Preferably, a single elastic tube spring is fitted around the outer periphery of the powder outlet pipe connecting pipe. The upper end of the single elastic tube spring abuts against the elastic tube connecting seat of the elastic tube, and the lower end of the single elastic tube spring abuts against a spring baffle. The spring baffle has an installation connection hole or installation connection limiting groove that mates with the elastic tube mounting post. The spring baffle is press-fitted and fixed to the elastic tube mounting post by a washer screw. The spring baffle has a baffle through hole for the powder outlet pipe to pass through freely. After the upper end of the powder outlet pipe passes through the spring baffle and the single elastic tube spring, it is threadedly connected to the external thread section of the powder outlet pipe connecting pipe. This improves the stability, reliability, and effectiveness of the elastic vibration installation connection limiting of the elastic tube, and improves the stability, simplicity, reliability, and effectiveness of the same-frequency elastic vibration for removing residual powder from the powder outlet pipe.

[0010] Preferably, the inner circumference of the single elastic tube spring is larger than the outer circumference of the powder outlet pipe. This improves the flexibility and reliability of the single elastic tube spring's free compression and elastic rebound on the outer circumference of the upper section of the powder outlet pipe.

[0011] Preferably, the length of each of the several elastic tube springs is greater than the length of the elastic tube mounting post, and the inner circumference of each elastic tube spring is greater than the outer circumference of the elastic tube mounting post. This improves the flexibility, reliability, and effectiveness of the elastic tube springs in performing elastic vibration to remove residual powder.

[0012] Preferably, the powder outlet support is equipped with a positioning post, which, along with the elastic tube mounting post, is distributed on the outer periphery of the upper powder outlet pipe. The elastic tube connector has a positioning hole that mates with the positioning post. The positioning post can freely pass through the positioning hole and is positioned on the outer periphery of the upper end of the powder outlet pipe, providing further auxiliary positioning and limiting of the powder outlet pipe. This improves the reliability and effectiveness of the auxiliary positioning and limiting of the elastic tube and the powder outlet pipe, and enhances the safety, reliability, and effectiveness of the elastic vibration for removing residual powder.

[0013] Preferably, the powder outlet support is inclinedly connected to the upper end of the powder outlet seat, and the elastic tube mounting column and the upper powder outlet pipe are inclined downwards. This reduces powder flying during grinding and improves the safety, reliability, and effectiveness of elastic vibration for removing residual powder.

[0014] Preferably, the aforementioned elastic tube springs adopt a round wire spring, a counter-wave spring, or a counter-wave spring flat-end compression spring structure. This improves the accuracy and effectiveness of elastic vibration residual powder removal elastic force control, reduces equipment damage, occupies less space, and reduces the space occupied by the elastic tube springs.

[0015] The beneficial effects of this invention are as follows: Through the mutual elastic force of the elastic tube mounting post, the elastic tube, and several elastic tube springs, a synchronous elastic vibration is provided to the powder outlet tube connected to the powder outlet tube connecting pipe. This vibrates away any residual coffee powder that may be present in the powder outlet tube, preventing the formation of residual coffee powder inside or on the inner wall of the powder outlet tube during the coffee bean grinding process, thus avoiding waste, improving the purity of the coffee's taste, and preventing bacterial growth. Residual coffee powder can be automatically dislodged from the powder outlet tube without disassembling it. Simultaneously, since the elastic tube is connected to the elastic tube mounting post on the powder outlet support, the vibration force also affects the upper powder outlet tube and the powder outlet tube connecting pipe of the powder outlet support, effectively achieving automatic elastic vibration powder removal from the upper powder outlet tube and the powder outlet tube connecting pipe. Elastic vibration powder removal is more thorough and cleaner. Automatic and efficient elastic vibration powder removal can be performed without disassembling the lower powder outlet tube.

[0029] The powder outlet support 20 is inclinedly connected to the upper end of the powder outlet seat 10. The elastic tube mounting post and the upper powder outlet pipe are inclined downwards. The upper end of the powder outlet pipe 60 is threadedly connected to the powder outlet pipe connecting pipe 31, and is also inclined downwards simultaneously (see...). Figure 4 (As indicated by the arrow).

[0030] Example 1:

[0031] Figure 5 , Figure 6 , Figure 7 In the embodiment shown, a single elastic tube spring 40A is fitted around the outer periphery of the powder outlet pipe connecting pipe 31. The upper end of the single elastic tube spring 40A abuts against the elastic tube connecting seat 30 of the elastic tube.

Figure 4 , Figure 7The coffee grinder grinds the coffee beans in the bean hopper 82, and the ground coffee powder is discharged from the powder outlet tube 60 at an angle into the powder receiving container 81 on the grinder base 80. During the grinding process, the powder outlet tube 60 automatically and efficiently removes residual coffee powder without needing to be disassembled, thus better meeting the needs of high-efficiency grinding applications and avoiding waste and bacterial growth, making grinding healthier, more hygienic, and safer. Simultaneously, because the elastic tube is connected to the elastic tube mounting post on the powder outlet support, the vibration force also affects the upper powder outlet tube and the powder outlet tube connecting tube of the powder outlet support, effectively achieving automatic elastic vibration powder removal from the upper powder outlet tube and the powder outlet tube connecting tube. This makes the elastic vibration powder removal more thorough, cleaner, and more comprehensive. Of course, after prolonged use, it is necessary to remove the gasket screws and the powder outlet tube for cleaning if necessary.
