Description

Technical Field

[0001] This utility model relates to the field of coffee grinder technology, specifically a household coffee grinder. Background Technology

[0002] A coffee grinder is a device that mechanically grinds coffee beans into a powder suitable for brewing. Its core function is to control the coarseness of the grind particles to ensure the uniformity of taste and flavor during coffee brewing. It achieves efficient grinding by using electricity to drive the grinding discs.

[0003] In home use, coffee grinders are not used as frequently as commercial grinders. Each grinding process leaves some powder and debris inside. If not used continuously and cleaned in time, mold can easily grow, especially in the more humid air environments of the south. Therefore, cleaning a home grinder is usually done after each grinding session. However, for motor-driven grinders, which have an internal motor structure, directly rinsing the inside with water can easily cause water stains to seep into the motor or the base of the electrical equipment, causing unnecessary danger. Therefore, it is necessary to design a grinder that allows for quick separation of the grinding body and the base of the electrical equipment. Utility Model Content

[0004] The purpose of this invention is to provide a household coffee grinder to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a base and a grinding frame. A drive shaft is rotatably connected to the center of the upper end of the base. A protrusion is fixed to the outside of the drive shaft. A drive motor that drives the drive shaft to rotate is installed inside the base. The grinding frame is installed on the upper end of the base via a quick-release assembly. A grinding groove is formed inside the grinding frame. A fixed grinding sleeve is fixed to the side wall of the grinding groove. A conical grinding disc is rotatably connected to the fixed grinding sleeve via a connecting shaft. A connecting sleeve adapted to the drive shaft is rotatably connected to the bottom of the grinding frame. The bottom of the connecting shaft is fixed to the connecting sleeve, and the upper end of the drive shaft is inserted into the connecting sleeve.

[0006] Preferably, a hopper is installed at the upper end of the grinding frame, and an insertion sleeve is fixed at the bottom of the hopper. The insertion sleeve is inserted into the opening at the upper end of the grinding groove.

[0007] Preferably, the bottom of the grinding tank is provided with an inclined surface, and the side wall of the grinding tank is provided with a discharge port. A guide frame is fixed outside the grinding frame and below the discharge port.

[0008] Preferably, the quick-assembly assembly includes a side plate, an annular plate, a plug block, and a socket. The plug block is fixed to the upper end of the base and is distributed circumferentially around the drive shaft. The socket is opened at the bottom of the grinding frame and is aligned with the plug block. The upper end of the plug block is inserted into the socket.

[0009] Preferably, the annular plate is rotatably connected to the upper end of the base and located around the insert block, the side plates are fixed to the bottom of the grinding frame and are symmetrically distributed, and a pair of end plates are fixed to the upper end of the annular plate.

[0010] Preferably, the end plate has a positioning hole, and a positioning block is installed on the side plate at a position corresponding to the positioning hole. The bottom of the positioning block is slidably connected to the side plate and is equipped with an ejector spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the electric drive structure and grinding structure of the coffee grinder are set as a detachable combination structure. When cleaning the inside of the coffee grinder, the grinding frame can be easily removed from the base for cleaning. This not only allows for quick internal cleaning with water, but also prevents water from entering the electric drive structure. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: including a base 1 and a grinding frame 2. A drive shaft 11 is rotatably connected to the center of the upper end of the base 1. A protrusion 12 is fixed on the outside of the drive shaft 11. A drive motor that drives the drive shaft 11 to rotate is installed inside the base 1. The grinding frame 2 is installed on the upper end of the base 1 through a quick-release assembly. A grinding groove 3 is opened inside the grinding frame 2. A fixed grinding sleeve 32 is fixed on the side wall of the grinding groove 3. A conical grinding disc 33 is rotatably connected inside the fixed grinding sleeve 32 through a connecting shaft 31. A connecting sleeve 34 that is adapted to the drive shaft 11 is rotatably connected to the bottom of the grinding frame 2. The bottom of the connecting shaft 31 is fixed on the connecting sleeve 34, and the upper end of the drive shaft 11 is inserted into the connecting sleeve 34.

[0019] A hopper 4 is installed on the upper end of the grinding frame 2. An insertion sleeve 41 is fixed at the bottom of the hopper 4. The insertion sleeve 41 is inserted into the upper opening of the grinding tank 3. The bottom of the grinding tank 3 is provided with an inclined surface, and a discharge port 21 is opened on the side wall of the grinding tank 3. A guide frame 22 is fixed on the outside of the grinding frame 2 and below the discharge port 21.

[0020] The quick-assembly assembly includes a side plate 6, an annular plate 5, a plug 13, and a socket 23. The plug 13 is fixed to the upper end of the base 1 and is distributed around the periphery of the drive shaft 11. The socket 23 is opened at the bottom of the grinding frame 2 and is aligned with the plug 13. The upper end of the plug 13 is inserted into the socket 23. The annular plate 5 is rotatably connected to the upper end of the base 1 and is located around the plug 13. The side plate 6 is fixed to the bottom of the grinding frame 2 and is symmetrically distributed. A pair of end plates 51 are fixed to the upper end of the annular plate 5. The end plates 51 are provided with positioning holes 52. Positioning blocks 61 are installed on the side plate 6 at positions corresponding to the positioning holes 52. The bottom of the positioning blocks 61 is slidably connected to the side plate 6 and is equipped with an ejector spring 62.

[0021] Working principle: First, connect the entire device to an external power source. Then, assemble the grinding frame 2 onto the upper part of the base 1. Pour coffee beans into the hopper 4. The drive motor then rotates the drive shaft 11, which in turn rotates the connecting shaft 31 and the conical grinding disc 33, achieving the grinding purpose. The ground powder can be discharged through the discharge port 21. During internal cleaning, the positioning block 61 can be squeezed, causing it to slide out of the positioning hole 52 under the compression of the ejector spring 62. Then, the annular plate 5 is rotated, positioning the side plate 6 in the gap between the end plates 51, allowing the side plate 6 to be easily pulled out of the annular plate 5. The purpose of disassembly is to insert the side plate 6 into the annular plate 5. At this time, the insert block 13 will be inserted into the insertion hole 23 to achieve horizontal positioning. Then, the annular plate 5 is rotated so that the end plate 51 rotates above the side plate 6, which limits the vertical pulling of the grinding frame 2 and achieves the purpose of fixing. At this time, the positioning block 61 is pushed into the positioning hole 52 by the push of the ejector spring 62 to prevent the annular plate 5 from rotating and to ensure the stability after fixing. This achieves quick disassembly and assembly between the grinding frame 2 and the base 1. After disassembly, the inside of the grinding frame 2 can be washed and cleaned separately with water, making the operation more convenient and eliminating the risk of cleaning water stains entering the power base 1.
