[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1:

[0029] like Figure 1-3 The image shows a portable coffee grinder provided in this embodiment, including a motor compartment 1, a coffee bean compartment 2, and a powder collection compartment 3;

[0030] The motor compartment 1 contains a motor 101, a drive rod 102, and a drive gear set. The output end of the motor is rotatably connected to the drive rod 102 via the drive gear set. The bean compartment 2 contains a driven rod 201 and a blade 202. Both the motor compartment 1 and the bean compartment 2 are equipped with a snap-fit ​​structure. When grinding beans, the motor compartment 1 can be installed on top of the bean compartment 2 via the snap-fit ​​structure. The powder collection compartment 3 is installed on the bottom of the bean compartment 2 via a snap-fit ​​structure. The bottom of the drive rod 102 is connected to the top of the driven rod 201. The motor drives the drive rod 102 and the driven rod 201 to rotate, thereby driving the blade 202 to rotate and grind the beans. After grinding, the lower part of the bean compartment 2 can be stored in the powder collection compartment 3, and the motor compartment 1 can be stored in the bean compartment 2. At this time, the drive rod 102 is sleeved on the outside of the driven rod 201.

[0031] The motor output end is provided with a driving tooth 103, and the drive rod 102 is provided with a driven tooth 104. The driving tooth and the driven tooth mesh with each other. The upper and lower ends of the drive rod 102 are rotatably connected to the motor compartment 1 through bearings. The drive rod 102 is a hollow hexagonal prism structure, and the driven rod 201 is a hexagonal prism structure. When working, the motor compartment 1 is snapped into the top of the bean compartment 2, and the bottom of the drive rod 102 is sleeved on the outside of the top of the driven rod 201. After the motor 101 is started, it drives the drive rod 102 to rotate through the motor output end, the driving tooth, and the driven tooth. The drive rod 102 drives the driven rod 201 to rotate, thereby driving the cutter 202 to rotate and grind the coffee beans into coffee powder.

[0032] This utility model discloses a portable coffee grinder. During grinding, the motor compartment is snapped onto the top of the coffee compartment via a snap-fit ​​structure, and the bottom of the drive rod is sleeved onto the top of the driven rod, thereby driving the blades to rotate and grind the coffee. After grinding, the drive rod can slide along the driven rod and be sleeved on the outside of the driven rod, thus allowing the motor compartment to be stored inside the coffee compartment, improving space utilization, significantly reducing the storage volume, and enhancing the portability of the coffee grinder.

[0033] Preferably, the locking structure on the motor compartment 1 is an elastic locking pin 105 provided at the bottom of the motor compartment 1 and extending radially outward, and the locking structure on the bean compartment 2 is a locking groove 205 provided on the wall of the bean compartment 2. After the elastic locking pin pops outward through the locking groove, the motor compartment 1 is locked onto the top of the bean compartment 2. External force can drive the elastic locking pin to retract inward and exit the locking groove, and drive the motor compartment 1 to slide into the bean compartment 2 for storage. The outer diameter of the motor compartment 1 is smaller than the inner diameter of the bean compartment 2, which facilitates its storage in the bean compartment 2. The motor compartment can be separated from the bean compartment by driving the elastic locking pin to retract inward and exit the locking groove with external force, moving the motor compartment away from the bean compartment, which facilitates the cleaning and maintenance of the grinder.

[0034] The bean hopper 2 is equipped with an opening and closing door 208. When grinding beans, open the opening and closing door 208, put the coffee beans into the bean hopper 2, close the opening and closing door, and start the motor to grind the beans.

[0035] In this embodiment, the bottom of the coffee grinder's bean hopper 122 can be stored inside the powder collection chamber 123, and the specific structure is as follows:

[0036] like Figure 1As shown, the bean hopper 2 has two sets of retaining structures on its wall: a storage retaining structure 203 and a connecting retaining structure 204. The storage retaining structure 203 is positioned higher than the connecting retaining structure 204. The powder collection chamber 3 has a protrusion structure 301 on its side wall. When grinding coffee beans, the bottom surface of the connecting retaining structure 204 abuts against the top surface of the protrusion structure 301, at which point the bean hopper 2 abuts against the top of the powder collection chamber 3. After grinding, the bean hopper 2 is rotated so that the bottom surface of the storage retaining structure abuts against the top surface of the protrusion structure, at which point the bottom of the bean hopper 2 contacts the bottom of the powder collection chamber 3, and the lower part of the bean hopper 2 is stored inside the powder collection chamber 3. This coffee grinder significantly reduces the size of the grinder after storage by storing the lower part of the bean hopper 2 inside the powder collection chamber 3 and by storing the motor chamber 1 inside the bean hopper 2, achieving efficient space utilization and significantly improving the product's portability.

[0037] Example 2:

[0038] A coffee grinder, differing from Example 1 only in that, as Figure 4 As shown, in this embodiment, the locking structure on the motor compartment 1 is an L-shaped slide rail 106, and the locking structure on the bean compartment 2 is a radial locking pin 206 provided on the compartment wall; the L-shaped slide rail includes a first slide rail 106a arranged laterally and a second slide rail 106b connected to one end of the first slide rail and extending vertically upward; the inner side of the radial locking pin 206 can slide within the first slide rail or the second slide rail. When the radial locking pin 206 is in the first slide rail, the motor compartment 1 is locked onto the top of the bean compartment 2; when the radial locking pin 206 is in the first slide rail, the motor compartment 1 is locked onto the top of the bean compartment 2. When pin 206 slides from the first slide into the second slide and is at the top of the second slide, the motor compartment 1 is housed inside the bean compartment 2. The lower side of the first slide is connected to the third slide 107. When it is necessary to remove the motor compartment 1 from the bean compartment 2, rotate the motor compartment 1 so that the inner side of the radial locking pin enters the third slide. Then apply a drive to the motor compartment 1 to move it away from the bean compartment 2, which can separate the motor compartment 1 from the bean compartment 2. This makes it easy to clean the residual coffee bean residue in the bean compartment and motor compartment, and also makes it easy to inspect and replace the parts of the grinder.

[0039] Example 3:

[0040] A coffee grinder, differing from Example 1 only in that, as Figure 5As shown, in this embodiment, the snap-fit ​​structure on the motor compartment 1 is a snap-fit ​​slide 108, and the snap-fit ​​structure on the bean compartment 2 is a radial elastic snap-fit ​​pin 207 provided on the wall of the bean compartment 2. The snap-fit ​​slide 108 is vertically arranged on both sides of the motor compartment 1, and a fixed snap-fit ​​groove 109 is provided in the snap-fit ​​slide. When no external force is applied, under the elastic action of the spring inside the radial elastic snap-fit ​​pin, the inner side of the radial elastic snap-fit ​​pin is arranged in the snap-fit ​​slide. When the inner side of the radial elastic snap-fit ​​pin enters the fixed snap-fit ​​groove, the motor compartment 1 is snapped into the top of the bean compartment 2. When an external force pulls the radial elastic snap-fit ​​pin outward, the inner side of the radial elastic snap-fit ​​pin moves out of the fixed snap-fit ​​groove, and the external force drives the motor compartment to slide into the bean compartment, and the motor compartment 1 is housed inside the bean compartment 2.

[0041] like Figure 6 As shown, the radial elastic locking pin 207 includes a locking pin 207a, a fixing frame 207b, a spring 207c, and a connecting plate 207d. The fixing frame 207b is provided on the inner wall of the bean hopper 2. One end of the locking pin 207a is located on the outer side of the bean hopper 2, and the other end of the locking pin 207a extends through the fixing frame 207b to the outside of the fixing frame 207b. The connecting plate 207d is provided on the locking pin. The spring 207c and the connecting plate 207d are located inside the fixing frame 207b. The two ends of the spring 207c abut against the inner wall of the fixing frame 207b and the connecting plate 207d, respectively. The inner side of the locking pin 207a can enter the fixing slot 109 to fix the motor hopper 1 on the upper side of the bean hopper 2. External force drives the locking pin 207a to move away from the motor compartment, and the connecting plate moves within the fixed frame. At the same time, the spring within the fixed frame is compressed, pulling the inner side of the locking pin away from the fixed slot 109. At this time, the motor compartment can be slid into the bean compartment, allowing the motor compartment to be stored inside the bean compartment. In its natural state, due to the spring force, the inner side of the locking pin can be inserted into the fixed slot 109, locking the motor compartment at the top of the bean compartment, thus enabling the bean grinding operation.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
