[0002] In daily life, there are often situations where it is necessary to grind food, medicine, etc. These items usually need to be stored intact, so each time they are used, the part to be taken out needs to be ground separately. Most existing portable grinders are rechargeable or plugged in, so when going out, you not only need to carry the grinder itself, but also the charging equipment, which reduces portability. Moreover, when used outdoors, they are limited by the lack of power supply. Therefore, there is a need to develop a new type of portable grinder to solve the shortcomings of existing technology. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a convenient grinder.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a portable grinder, comprising a grinding cylinder, an adjustable discharge head connected to the bottom of the grinding cylinder, a manual grinding mechanism connected to the top of the grinding cylinder, an electric mechanism connected to the top of the manual grinding mechanism, a grinding rod disposed inside the grinding cylinder, and the upper and lower ends of the manual grinding mechanism being connected to the grinding rod and output shaft inside the grinding cylinder and the electric mechanism, respectively.

[0005] The manual grinding mechanism includes an integrated assembly fixedly connected between the grinding cylinder and the electric mechanism. A transmission assembly is movably sleeved inside the integrated assembly. The bottom of the transmission assembly extends into the interior of the grinding cylinder and is connected to the grinding rod. The top of the transmission assembly extends into the interior of the electric mechanism and is connected to the bottom of the output shaft. A pull rope assembly is connected to the outer surface of the transmission assembly, and the other end of the pull rope assembly extends to the outside of the integrated assembly.

[0006] As a preferred technical solution of this utility model, the integrated component includes an integrated cover threaded between the grinding cylinder and the electric mechanism, the integrated cover having an integrated cavity inside, and a partition plate located at the bottom of the pull rope assembly and the outside of the transmission assembly being fixedly sleeved inside the integrated cavity.

[0007] As a preferred technical solution of this utility model, the transmission component includes a transmission sleeve that is movably fitted inside the integrated cavity, and a transmission shaft is movably fitted inside the transmission sleeve. The upper and lower ends of the transmission shaft pass through the integrated cover and are fixedly connected to the output shaft and the grinding rod, respectively.

[0008] As a preferred embodiment of this utility model, the integrated cover is provided with a first spring located at the bottom of the partition plate and outside the transmission sleeve. The two ends of the first spring are respectively connected to the inner wall of the integrated cavity and the outer surface of the transmission sleeve.

[0009] As a preferred embodiment of this utility model, a plurality of uniformly distributed one-way transmission components are embedded in the top of the transmission sleeve. One end of the one-way transmission component is connected to the transmission sleeve, and the other end of the one-way transmission component is connected to the transmission shaft.

[0010] As a preferred embodiment of this utility model, the one-way transmission assembly includes a transmission groove formed on the top of the transmission sleeve and the outside of the transmission shaft. A transmission gear is rotatably connected inside the transmission groove. The transmission gear is fixedly sleeved on the outer surface of the transmission shaft.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a convenient grinder, including a grinding cylinder 1, an adjustable discharge head 2 connected to the bottom of the grinding cylinder 1, a manual grinding mechanism 3 connected to the top of the grinding cylinder 1, an electric mechanism 4 connected to the top of the manual grinding mechanism 3, a grinding rod arranged inside the grinding cylinder 1, and the upper and lower ends of the manual grinding mechanism 3 connected to the grinding rod and output shaft inside the grinding cylinder 1 and the electric mechanism 4, respectively.

[0023] The manual grinding mechanism 3 includes an integrated component 31 fixedly connected between the grinding cylinder 1 and the electric mechanism 4. A transmission component 32 is movably sleeved inside the integrated component 31. The bottom of the transmission component 32 extends into the interior of the grinding cylinder 1 and is connected to the grinding rod. The top of the transmission component 32 extends into the interior of the electric mechanism 4 and is connected to the bottom of the output shaft. A pull rope component 33 is connected to the outer surface of the transmission component 32. The other end of the pull rope component 33 extends to the outside of the integrated component 31. Due to the setting of the transmission component 32, the motor in the electric mechanism 4 can automatically drive the grinding rod in the grinding cylinder 1 to rotate through the transmission component 32. Moreover, the pull rope component 33 allows the user to easily manually control the rotation of the grinding rod in the grinding cylinder 1, avoiding the inconvenience caused by the lack of charging equipment when traveling, thereby effectively improving the portability and usability of the device.

[0024] The integrated component 31 includes an integrated cover 311 threaded between the grinding cylinder 1 and the electric mechanism 4. The integrated cover 311 has an integrated cavity 312 inside. A partition plate 313 located at the bottom of the pull rope assembly 33 and the outside of the transmission assembly 32 is fixedly sleeved inside the integrated cavity 312. Due to the setting of the partition plate 313, it can ensure that the first spring 314 and the pull rope 331 can be connected to the transmission sleeve 321 at the same time, and can avoid the pull rope 331 and the first spring 314 from interfering with each other.

[0025] The transmission assembly 32 includes a transmission sleeve 321 that is movably fitted inside the integrated cavity 312. A transmission shaft 322 is movably fitted inside the transmission sleeve 321. The upper and lower ends of the transmission shaft 322 pass through the integrated cover 311 and are fixedly connected to the output shaft and the grinding rod, respectively.

[0026] The integrated cover 311 is equipped with a first spring 314 located at the bottom of the partition plate 313 and outside the transmission sleeve 321. The two ends of the first spring 314 are connected to the inner wall of the integrated cavity 312 and the outer surface of the transmission sleeve 321, respectively. Due to the setting of the first spring 314, under the action of its elastic restoring force, it can automatically drive the transmission sleeve 321 to rotate in the opposite direction, thereby restoring the winding of the pull rope 331. This ensures that the pull rope 331 can pull the integrated cover 311 again and drive the transmission shaft 322 to rotate through the transmission sleeve 321 with the cooperation of the one-way transmission component 34.

[0027] The top of the transmission sleeve 321 is embedded with several evenly distributed one-way transmission components 34. One end of the one-way transmission component 34 is connected to the transmission sleeve 321, and the other end of the one-way transmission component 34 is connected to the transmission shaft 322.

[0028] The one-way transmission component 34 includes a transmission groove 341 located on the top of the transmission sleeve 321 and the outside of the transmission shaft 322. A transmission gear 342 is rotatably connected inside the transmission groove 341. The transmission gear 342 is fixedly sleeved on the outer surface of the transmission shaft 322. A plurality of evenly distributed abutment rods 343 are movably connected inside the transmission groove 341. One end of the abutment rod 343 abuts against the outer surface of the transmission gear 342, and the other end of the abutment rod 343 is movably sleeved with a positioning shaft 344. The positioning shaft 344 has an "I" shaped cross section. A second spring 345 is connected between the positioning shaft 344 and the abutment rod 343. Due to the setting of the one-way transmission component 34, the cooperation between the transmission sleeve 321 and the transmission shaft 322 ensures that when the motor in the electric mechanism 4 drives the grinding rod to rotate through the transmission component 32, it will not drive the pull rope component 33 to move. At the same time, when the pull rope component 33 drives the transmission component 32 to rotate, it will not be restricted by the motor, thereby ensuring the effect of electric and automatic grinding.

[0029] The pull cord assembly 33 includes a pull cord 331 disposed inside the integrated cavity 312 and on the top of the partition plate 313. The pull cord 331 is wound around the outside of the transmission sleeve 321. One end of the pull cord 331 is fixedly connected to the outer surface of the transmission sleeve 321, and the other end of the pull cord 331 passes through the integrated cavity 312 and extends to the outside of the integrated cover 311 and is fixedly connected to a pull head 332. Due to the setting of the pull head 332, it can be ensured that the outer end of the pull cord 331 is always located outside the integrated assembly 31, thereby facilitating the operation of the user.

[0030] Working principle and usage process of this utility model:

[0031] Assemble the equipment as shown in the figure. Unscrew the manual grinding mechanism 3 and remove the manual grinding mechanism 3, electric mechanism 4 and grinding rod as a whole. Then, put the material to be ground into the grinding cylinder 1. After installing the manual grinding mechanism 3, electric mechanism 4 and grinding rod as a whole, start the motor inside the electric mechanism 4 by opening the top of the electric mechanism 4. The output shaft will drive the transmission shaft 322 to rotate, thereby driving the grinding rod inside the grinding cylinder 1 to rotate at high speed.

[0032] When the motor inside the electric mechanism 4 is turned off or there is no power, pulling the pull head 332 will drive the pull rope 331 to move, which in turn drives the transmission sleeve 321 to rotate. Since the rotation of the transmission sleeve 321 can cause the first spring 314 to rotate and increase its elastic restoring force under the restriction of the integrated cavity 312, while the transmission sleeve 321 rotates, it can push the transmission gear 342 to rotate through the abutment rod 343 under the restriction of the positioning shaft 344, which in turn drives the transmission shaft 322 to rotate, thereby driving the grinding rod inside the grinding cylinder 1 to rotate at high speed. After releasing the pull head 332, the transmission sleeve 321 can be driven to rotate quickly in the opposite direction under the action of the elastic restoring force of the first spring 314, so that the pull rope 331 can be reconnected and the pull rope assembly 33 can be pulled again, thereby realizing continuous manual drive.
