Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 5 As shown, a sampling spoon with vibration cleaning function includes: a handle 1, on which a vibration motor 103 is fixedly mounted, and the housing of the vibration motor 103 is fixedly connected to the handle 1; a spoon body 2, on which a connecting rod 201 is fixedly mounted, and the connecting rod 201 has a mounting groove 204 corresponding to the output shaft 10302 of the vibration motor 103, and the output shaft 10302 of the vibration motor 103 is installed inside the mounting groove 204; the connecting rod 201 is detachably connected to the output shaft 10302 of the vibration motor 103 through a connecting assembly.

[0034] The outer surface of the spoon body 2 is polished and coated with a nano anti-stick layer, which can reduce the friction between the powder and the spoon body 2, thereby reducing powder adhesion.

[0035] The handle 1 has a shell-like structure. A vibration motor 103 is installed inside the handle 1. The vibration motor 103 is electrically connected to a power module 102 via a push-button switch 101, which is also installed inside the handle 1. The push-button switch 101 is mounted on the side wall of the handle 1. The vibration motor 103 uses, but is not limited to, existing eccentric wheel 10301 DC motors (frequency 120Hz). An eccentric wheel 10301 is fixed on the motor's output shaft 10302; the diameter of the output shaft 10302 is smaller than the diameter of the mounting groove 204. Alternatively, the vibration motor 103 can be a magnetic levitation vibration motor 103 used in existing electric toothbrushes. In this case, the output shaft 10302 of the magnetic levitation vibration motor 103 will not vibrate but will only oscillate within a certain angle.

[0036] The power module 102 includes a battery box and a battery. The battery is detachably connected to the battery box. The handle 1 has a through hole corresponding to the battery box. The handle 1 is provided with a cover plate 104 corresponding to the through hole. The cover plate 104 is detachably connected to the handle 1 and is used to close the through hole. The battery can be a dry cell battery or a 3.7V lithium battery.

[0037] There are various models of spoon body 2, and different models of spoon body 2 have different capacities, which are suitable for sampling operations of different powders.

[0038] In some embodiments, the connecting assembly includes a tension spring 3, one end of which is detachably connected to a connecting rod 201, and the other end of which is connected to a handle 1. Multiple tension springs 3 are arranged circumferentially and evenly along the connecting axis. Hooks are fixed at both ends of the tension spring 3, and a crossbar 202 is fixed on the connecting rod 201. An annular limiting groove 203 corresponding to the hook is opened on the crossbar 202. The hook at one end of the tension spring 3 is connected to a connecting ring on the handle 1, and the hook at the other end of the tension spring 3 is located inside the annular limiting groove 203. When it is necessary to replace the spoon body 2 with a different model or to disassemble the spoon body 2 for maintenance, the hook can be disengaged from the annular limiting groove 203 and slide out of the crossbar 202, thus facilitating disassembly. When the vibration motor 103 is an eccentric wheel 10301 DC motor, the tension spring 3 not only fixes the spoon body 2 but also prevents the spoon body 2 from rotating with the output shaft 10302.

[0039] In other embodiments, the connecting assembly includes a tension spring 3, one end of which is detachably connected to a connecting rod 201, and the other end of which is connected to a handle 1. Multiple tension springs 3 are arranged circumferentially and evenly along the connecting axis. A mounting ring 205 is provided on the connecting rod 201, and the mounting ring 205 is fixedly installed on the outer side of the connecting rod 201. An ear plate 206 is fixedly provided on the outer wall of the mounting ring 205, and the ear plate 206 has a connecting hole 207. A hook at one end of the tension spring 3 is connected to the connecting ring on the handle 1, and a hook at the other end of the tension spring 3 is located inside the connecting hole 207. When it is necessary to replace the spoon body 2 with a different model or to disassemble the spoon body 2 for maintenance, the hook can be disengaged from the connecting hole 207 to disassemble the spoon body 2, improving ease of disassembly. The tension spring 3 also serves to fix the spoon body 2.

[0040] In other embodiments, (such as) Figure 6The connecting assembly (shown) includes a tension spring 3, one end of which is detachably connected to a connecting rod 201, and the other end of which is connected to a handle 1. Multiple tension springs 3 are arranged circumferentially along the connecting axis. A mounting ring 205 is provided on the connecting rod 201, and an ear plate 206 is fixed to the outer wall of the mounting ring 205. The ear plate 206 has a connecting hole 207. A hook at one end of the tension spring 3 is connected to the connecting ring on the handle 1, and a hook at the other end of the tension spring 3 is located inside the connecting hole 207. The mounting ring 205 is movably connected to the connecting rod 201 along its length. An external thread is provided on the outer side of the connecting rod 201 away from the spoon body 2. An adjusting ring 208 is provided on the outer side of the connecting rod 201, and an internal thread is provided on the inner side of the adjusting ring 208. The adjusting ring 208 is threadedly connected to the connecting rod 201. The mounting ring 205 is located between the adjusting ring 208 and the spoon body 2, and the adjusting ring 208 limits the movement of the mounting ring 205. When it is necessary to replace the spoon body 2 with a different model or to disassemble the spoon body 2 for maintenance, the spoon body 2 can be disassembled by disengaging the hook from the connecting hole 207, which facilitates disassembly. The tension spring 3 serves to fix the spoon body 2 in place. When it is necessary to adjust the vibration amplitude of the spoon body 2, the tension of the tension spring 3 can be adjusted by rotating the adjusting ring 208, thereby adjusting the vibration amplitude of the spoon body 2.

[0041] Work process:

[0042] When implementing this solution, after the sampling operation is completed, the vibration motor 103 is turned on to automatically clean the residual powder on the spoon surface through high-frequency vibration. Alternatively, the spoon body 2 can be immersed in the cleaning solution before turning on the vibration motor 103 to accelerate the cleaning operation. After the operation is completed, the vibration motor 103 is turned on to accelerate the drying of the liquid on the spoon body 2. This can quickly remove residual powder and improve sampling accuracy; simplify the cleaning process and reduce the risk of manual intervention and cross-contamination.
