Description

Coffee bean grinding system with antistatic structure Technical Field The utility model belongs to the technical field of coffee machines, and particularly relates to a coffee bean grinding system with an antistatic structure. Background When coffee beans are ground, the coffee particles are rubbed with each other continuously, static electricity is generated after friction, the static electricity can enable coffee powder to generate attraction/repulsion force for other objects, the coffee powder can be attracted with each other or can be adsorbed on other objects, in an existing bean grinder, a plasma generator is generally adopted to generate negative ions so as to neutralize the static electricity of the coffee powder, but the specific design has obvious defects. For example, in case 1 (patent CN 206183046U), the electrode probe directly extends into the powder outlet channel to contact with the coffee powder, while negative ions can be released efficiently, the coffee powder is easy to accumulate on the surface of the probe after long-term use, so that ion release is blocked, the powder flying preventing function is invalid, and frequent cleaning and maintenance are required. However, in the conventional racing structure of case 2, although the electrode probe is fixed on the machine body to avoid powder accumulation, the negative ions cannot effectively cover the powder flow area due to the too far distance between the probe and the powder outlet channel, so that the powder flying prevention efficiency is greatly reduced, and the problem of powder sticking caused by static electricity in the powder outlet channel cannot be solved. Both schemes have obvious defects in practicality, durability and efficiency, and a novel structural design capable of avoiding powder accumulation of a probe and ensuring the action distance of negative ions is needed. Disclosure of utility model Object of the utility model In order to overcome the defects, the utility model aims to provide a coffee bean grinding system with an antistatic structure, so as to solve the technical problems that an electrode probe in the existing coffee bean grinding machine is in direct contact with coffee powder to cause powder accumulation failure or is far away from a powder outlet channel to cause low negative ion efficiency. (II) technical scheme In order to achieve the above purpose, the technical scheme provided by the application is as follows: The coffee bean grinding system with the antistatic structure comprises a shell, an anion generating device, an electrode probe, an anion generating device and a control unit, wherein the shell is provided with a powder outlet channel, a grinding assembly is rotatably arranged in the shell, coffee beans are ground to form coffee powder and are output from the powder outlet channel, and the electrode probe is arranged outside the powder outlet channel and extends along the length direction of the powder outlet channel and is electrically connected with the anion generating device and can carry static electricity on the powder outlet channel; through arranging the electrode probe outside the powder outlet channel and extending along the length direction thereof, the double effects of static elimination and physical isolation are realized, and the structure enables negative ions to directly act on the surface of the powder outlet channel, so that the static adsorption phenomenon in the coffee powder conveying process is effectively eliminated, and meanwhile, the problem of powder accumulation failure caused by direct contact of the probe and the coffee powder is avoided. In some embodiments, the upper end of the electrode probe is positioned lower than the upper end powder inlet of the powder outlet channel; The height of the probe is designed to be lower than that of the powder inlet, so that the concentrated release of negative ions in a key area of the powder outlet channel is ensured, and the negative ions can be efficiently acted on falling coffee powder. In some embodiments, the power supply probe comprises a fixed seat, a power supply probe sleeve and a power supply probe sleeve, wherein the fixed seat is provided with a fixed plate surface at the upper end and a fixed sleeve sleeved with the power supply probe through the fixed plate surface at the lower end; The fixing seat is arranged, so that accurate positioning and quick assembly of the electrode probe can be realized, the vertical extension design of the fixing sleeve ensures that the probe and the powder outlet channel are kept in parallel, static electricity is fully removed from the whole powder outlet channel, and meanwhile, the free adjustment of the length direction of the probe is realized through the through structure, so that the mounting requirements of equipment of different models are met. In some embodiments, the outer side surface of the shell is provided with a mounting protection groove for embedding the electrode probe
