Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of brewing beverage machine, especially a coffee grinder device for grinding tea. BACKGROUND

[0002] The existing beverage machine uses a powder grinding device, which is generally a coffee machine, because the freshly ground coffee machine can better improve the quality of coffee, but in the consumer population, some people also like tea beverages, but the tea brewing machine is not as mature and rich as the coffee machine in terms of technology, and in view of the different properties and brewing requirements of tea leaves and coffee beans, people need to buy a tea brewing machine again if they have the need to make tea after buying a coffee machine.

[0003] In fact, although there are differences between tea powder brewing and coffee powder brewing, these differences can be changed in terms of water temperature and time through electric control adjustment, and the main reason is that the different fluidity of tea leaves and coffee beans will lead to a large difference in the structure of the powder grinding device, and the existing technology has not considered how to save the grinding tea device and the grinding coffee device. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a coffee grinder device for grinding tea, which can be converted from grinding coffee beans to grinding tea leaves through simple changes.

[0005] The technical scheme adopted by the utility model to solve its technical problem is: a coffee grinder device for grinding tea, which has an upper grinding disc and a lower grinding disc, both of which are annular and hollow, the lower grinding disc is fixed on the support disc of the disc shaft and rotates with the disc shaft, the support section of the disc shaft extending downward from the support disc is arranged in the lower cavity of the shell, the upper grinding disc and the lower grinding disc are located in the upper cavity of the shell, the upper cavity wall of the shell is provided with a powder outlet, the upper end face of the installation cylinder is fixed with the upper grinding disc, the installation cylinder is screwed on the upper opening part of the shell, the disc shaft has a screw rod installation section extending upward from the support disc, and has a replaceable material driving screw, the material driving screw is vertically screwed on the screw rod installation section, the upper opening of the installation cylinder is provided with a replaceable material storage cylinder, the conical surface of the material storage cylinder downward and with a small opening downward is attached to the conical end surface of the installation cylinder upward and with a large opening upward, and the material driving screw extends into the material storage cylinder from the hollow part of the upper grinding disc and the lower grinding disc.

[0006] In the above scheme, the replaceable and detachable meanings are the same, mainly to reflect the difference between the fixed structure and the long-standing technical bias.

[0007] Specifically, in order to make the material better enter the grinding surface, especially not to cause the coffee beans to be stuck between the material driving screw and the lower grinding disc, causing the driving motor resistance to rise and the current to increase, and then alarm stop, therefore, the material driving screw thread outside is higher than the grinding surface of the upper grinding disc.

[0008] Specifically, in order to adjust the grinding fineness, the shell is provided with a mill gap adjuster for adjusting the distance between the upper mill and the lower mill.

[0009] Specifically, since the plastic part is easy to carry static charge, causing powder sticking, the metal discharge guide groove is mounted outside the powder outlet.

[0010] Specifically, a driving motor is provided, and a worm segment on the output shaft of the driving motor is engaged with a worm wheel mounted at the lower end of the disc shaft.

[0011] The beneficial effects of the present application are: the driving screw and the storage cylinder are designed as a detachable and replaceable structure, and the technical contribution is that the driving screw and the storage cylinder can be replaced on the hardware, and then the software setting and the selection of tea or coffee mode are matched, so that the user only needs to purchase the driving screw and the storage cylinder capable of accelerating the flow of tea leaves after purchasing the coffee grinding device, the user's capital investment is reduced under the condition of meeting the two use requirements, and the performance-price ratio of the product is improved.
