Description

Technical Field

[0001] The present invention relates to the technical field of coffee grinders, and particularly to a powder outlet structure and a coffee grinder adopting the powder outlet structure. Background Art

[0002] At present, the powder outlet of the existing coffee grinder is often integrally formed with the coffee grinder housing or fixed to the coffee grinder housing. The powder outlet is located below the cutter head. As the cutter head rotates, the ground powder is discharged through the powder outlet. However, due to the electrostatic adsorption of the powder, powder will accumulate on the inner wall of the pipeline of the powder outlet. On the one hand, it will cause waste (especially for coffee powder with high value). On the other hand, the powder accumulated in the powder outlet for a long time will also deteriorate and breed bacteria, affecting consumption. To solve the problem of powder accumulation in the powder outlet, the traditional solution is generally to use fingers to flick or tap the powder outlet after grinding, so that the powder outlet vibrates and the residual powder in the powder outlet is shaken off. However, since the powder outlet is integrated with the coffee grinder housing, the vibration amplitude of the powder outlet is limited and the powder cannot be shaken off well. It often requires multiple flicks or taps to clean the residual powder in the powder outlet, which is inconvenient to use. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems existing in the prior art, and provide a powder outlet structure and a coffee grinder adopting the powder outlet structure. By rotating the knob to drive the powder outlet pipe to vibrate up and down, the powder in the powder outlet pipe can be effectively shaken off, which is convenient to use.

[0004] To achieve the above object, the present invention is realized through the following technical solutions:

[0005] A powder outlet structure includes a powder outlet pipe. An upper bracket is provided at the upper part of the powder outlet pipe, and a lower bracket is provided at the lower part of the powder outlet pipe. The upper bracket and the lower bracket are connected by a connecting member. An annular upper tooth seat is provided on the outer wall of the powder outlet pipe. A plurality of upper vibration teeth are evenly provided along the circumference of the bottom of the upper tooth seat. A powder outlet nozzle is provided at the bottom of the lower bracket. A knob is provided at the top of the powder outlet nozzle. The knob is detachably connected to the powder outlet nozzle. The lower bracket is limited within the knob and the knob is rotatably connected to the lower bracket. An annular lower tooth seat is provided at the upper part of the powder outlet nozzle. Lower vibration teeth adapted to the upper vibration teeth are provided at the top of the lower tooth seat. The lower vibration teeth are in contact with the upper vibration teeth.

[0006] Preferably, central holes adapted to the powder outlet pipe are provided on both the upper bracket and the lower bracket, and the inner diameter of the central hole is larger than the outer diameter of the powder outlet pipe.

[0007] Preferably, the lower bracket includes a circular ring adapted to the lower tooth seat. A stop block extending outward is provided on the circular ring. The outer side surface of the stop block is an arc surface adapted to the inner surface of the knob. A limit block adapted to the stop block is provided on the inner wall of the knob. The stop block is located below the limit block.

[0008] Preferably, the powder outlet nozzle is threadedly connected to the knob.

[0009] Preferably, a spring is provided between the upper tooth seat and the upper bracket. The top end of the spring abuts against the upper bracket, and the bottom end abuts against the upper tooth seat.

[0010] Preferably, the upper tooth seat is provided with mounting holes adapted to the springs. The number of springs is at least two, and the multiple springs are evenly arranged along the circumferential direction of the upper tooth seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The powder outlet pipe of the present invention can move up and down. By rotating the knob, the lower vibrating teeth can be driven to rotate around the axis of the powder outlet pipe, so that the upper vibrating teeth and the lower vibrating teeth slide relative to each other. During the relative sliding of the upper vibrating teeth and the lower vibrating teeth, the upper vibrating teeth move along the tooth surface of the lower vibrating teeth, so that the upper tooth seat first moves upward and then moves downward under the action of gravity. The powder outlet pipe moves synchronously with the upper tooth seat. By rotating the knob, the powder outlet pipe can be driven to vibrate up and down, which can effectively shake off the powder in the powder outlet pipe and is convenient to use.

[0017] 2. The spring of the present invention gives a downward thrust to the powder outlet pipe, which can make the upper tooth seat quickly fall back after moving to the highest point, and can improve the vibration effect of the powder outlet pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by this application.

[0031] Embodiment 1: A powder outlet structure includes a powder outlet pipe 1. An upper bracket 2 is provided on the upper part of the powder outlet pipe 1, and a lower bracket 3 is provided on the lower part of the powder outlet pipe 1. The upper bracket 2 and the lower bracket 3 are connected by a connecting member, and the connecting member can be a screw. Corresponding screw mounting holes are provided on both the upper bracket 2 and the lower bracket 3. A connecting hole can be provided on the upper bracket 2, and the upper bracket 2 is fixed to the housing of the coffee grinder by screws. Preferably, central holes adapted to the powder outlet pipe 1 are provided on both the upper bracket 2 and the lower bracket 3, and the inner diameter of the central hole is larger than the outer diameter of the powder outlet pipe 1.

[0032] An annular upper tooth seat 4 is provided on the outer wall of the powder outlet pipe 1. The upper tooth seat 4 and the powder outlet pipe 1 can adopt an integral structure, and the axis of the upper tooth seat 4 coincides with the axis of the powder outlet pipe 1. A plurality of upper vibrating teeth 41 are evenly provided along the circumference of the bottom of the upper tooth seat 4.

[0033] At the bottom of the lower bracket 3, there is a powder outlet nozzle 6. At the top of the powder outlet nozzle 6, there is a knob 7. The knob 7 is detachably connected to the powder outlet nozzle 6. The knob 7 and the powder outlet nozzle 6 can be connected by a snap connection. Preferably, for the convenience of disassembling the knob and the powder outlet nozzle, the powder outlet nozzle 6 is threadedly connected to the knob 7. An external thread is machined on the powder outlet nozzle 6, and a corresponding internal thread is machined on the inner wall of the knob 7.

[0034] The lower bracket 3 is defined within the knob 7 and the knob 7 is rotatably connected to the lower bracket 3. The lower bracket 3 is located inside the knob 7, and the axis lines of the knob 7, the lower bracket 3, the upper bracket 2, and the powder outlet pipe 1 coincide. Preferably, for the convenience of assembling the present invention, the lower bracket 3 includes a circular ring 31 adapted to the lower tooth seat 8. On the circular ring 31, there is a blocking block 32 extending outward. The outer side surface of the blocking block 32 is an arc surface adapted to the inner surface of the knob 7. On the inner wall of the knob 7, there is a limiting block adapted to the blocking block 32. The blocking block 32 is located below the limiting block.

[0035] At the top of the powder outlet nozzle 6, there is an annular lower tooth seat 8. The lower tooth seat 8 and the powder outlet nozzle 6 can adopt an integral structure. At the top of the lower tooth seat 8, there is a lower shock tooth 81 adapted to the upper shock tooth 41. The lower shock tooth 81 abuts against the upper shock tooth 41.

[0036] When the present invention is in use, by rotating the knob 7, the lower tooth seat 8 rotates synchronously with the knob 7, which can drive the lower shock tooth 81 to rotate around the axis line of the powder outlet pipe 1, so that the upper shock tooth 41 and the lower shock tooth 81 slide relative to each other. During the relative sliding process of the upper shock tooth 41 and the lower shock tooth 81, the upper shock tooth 41 moves along the tooth surface of the lower shock tooth 81. Under the action of the spring 5, the upper tooth seat 4 moves up and down. The powder outlet pipe 1 moves synchronously with the upper tooth seat 4, so that the upper tooth seat 4 first moves upward and then moves downward under the action of gravity. By rotating the knob 7, the powder outlet pipe 1 can be driven to vibrate up and down, which can effectively shake off the powder in the powder outlet pipe and is convenient to use.

[0037] Preferably, to improve the vibration effect of the powder outlet pipe, a spring 5 is provided between the upper tooth seat 4 and the upper bracket 2. The top end of the spring 5 abuts against the upper bracket 2, and the bottom end abuts against the upper tooth seat 4. The spring 5 gives a downward thrust to the upper tooth seat 4. One spring 5 can be directly sleeved on the powder outlet pipe 1. Further, the number of springs 5 is at least two. The multiple springs 5 are evenly arranged along the circumferential direction of the upper tooth seat 4, and on the upper tooth seat 4, there are mounting holes 42 adapted to the springs 5. The mounting holes 42 are blind holes provided at the top of the upper tooth seat 4, which can ensure balanced force.

[0038] Preferably, to improve the vibration effect of the powder outlet pipe, both the upper shock tooth 41 and the lower shock tooth 81 include a vertical surface and an inclined surface, as shown in the attached Figure 4As shown, the vertical surface of the lower vibrating tooth 81 is located at one end of the highest point of the inclined surface. During the relative sliding of the upper vibrating tooth 41 along the inclined surface of the lower vibrating tooth 81, the upper tooth seat 4 gradually moves upward, overcoming the elastic force of the spring 5, and the spring 5 is compressed. When the upper vibrating tooth 41 slides to the highest point of the inclined surface of the lower vibrating tooth 81, under the action of the spring 5, the upper tooth seat 4 quickly drops, which can improve the vibration effect.

[0039] Preferably, in order to prevent the upper vibrating teeth and the lower vibrating teeth from being damaged due to collision, a groove 43 is provided between two adjacent upper vibrating teeth 41.

[0040] Preferably, in order to facilitate the rotation of the knob, anti-slip lines are provided on the outer wall of the knob 7.
