Description

Technical Field

[0001] The utility model relates to a coffee bean grinder and an anti-static device thereof. Background Art

[0002] A coffee grinder primarily grinds coffee beans into ground coffee using upper and lower conical or flat blades. During the crushing and grinding process, friction between the ground coffee and the conical blades causes the ground coffee to acquire a certain electrical charge. This can cause flying coffee powder as it exits the discharge channel, or it can stick directly to the discharge channel, causing problems for the user. The usual solution is to spray the beans before grinding. However, automatic grinders typically store the beans in a hopper, making operation inconvenient. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide a coffee bean grinder and an anti-static device thereof.

[0004] In order to solve the above technical problems, the utility model provides an anti-static device for a coffee bean grinder, the anti-static device comprising a positive probe and a negative probe, the positive probe and the negative probe being arranged on both sides of the outer side of the powder outlet of the coffee bean grinder, ionizing the air between the positive probe and the negative probe to remove static electricity from the powder outlet; at least one of the positive probe and the negative probe extending a distance along the axial direction of the powder outlet, or at least one of the positive probe and the negative probe extending a distance along a direction intersecting the axial direction of the powder outlet;

[0005] The anti-static device further includes a baffle plate, which includes an opening corresponding to the powder outlet. An internal accommodating space is formed between the baffle plate and the outer side of the powder outlet, and the positive probe and the negative probe are arranged in the internal accommodating space.

[0006] In a more preferred embodiment, the opening of the baffle is spaced apart from the end of the powder outlet along the axial direction of the powder outlet; and the positive electrode probe and the negative electrode probe both extend beyond the end of the powder outlet.

[0007] In a more preferred embodiment, the anti-static device includes a first fixing frame and a second fixing frame, the first fixing frame is arranged on the motor of the bean grinder, the second fixing frame is arranged on the baffle plate of the bean grinder, the negative probe is arranged on the first fixing frame, and the positive probe is arranged on the second fixing frame.

[0008] The utility model also provides a bean grinder, comprising the anti-static device of the bean grinder.

[0009] In a more preferred embodiment, the bean grinder includes a motor, a bean grinding module and a powder discharge channel; the motor is used to drive the bean grinding module to grind beans, the powder discharge channel is connected to the bean grinding module, and the powder discharge channel forms the powder outlet.

[0010] Compared with the existing technology, the technical solution of the utility model has the following beneficial effects:

[0011] The anti-static device includes a positive probe and a negative probe, which are arranged on both sides of the powder outlet of the powder outlet channel. The positive probe and the negative probe ionize the air between the positive probe and the negative probe to remove static electricity from the powder outlet. At least one of the positive probe and the negative probe extends a distance along the axial direction of the powder outlet, or at least one of the positive probe and the negative probe extends a distance in a direction intersecting the axial direction of the powder outlet. The anti-static device also includes a baffle, which includes an opening corresponding to the powder outlet. The baffle forms an internal accommodating space between the baffle and the outer side of the powder outlet, and the positive probe and the negative probe are arranged in the internal accommodating space. Because the positive probe and the negative probe both extend beyond the end of the powder outlet, the anti-static function can be achieved within a certain distance from the powder outlet, and the anti-powder sticking effect is good. The provision of the baffle can prevent users from touching the positive probe or the negative probe, which may cause injury to the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Certain directional terms used in the following description of the drawings, such as "inner," "outer," "above," "below," and other directional terms, should be understood to have their normal meanings and refer to those directions when the drawings are normally viewed. Unless otherwise indicated, the directional terms used in this specification are generally in accordance with conventional directions understood by those skilled in the art.

[0017] The terms “first”, “second” and similar terms used in the present invention do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0018] See Figure 1-Figure 3 A bean grinder comprises a housing, a motor 2, a bean grinding module 3, a transmission mechanism 4, a powder discharge channel 5, and an anti-static device 6. The bean grinding module 3, the transmission mechanism 4, and the motor 2 are arranged in the housing. The motor 2 is connected to the bean grinding module 3 to drive the cutting tools of the bean grinding module 3 to rotate. The transmission mechanism 4 is connected to the bean grinding knife group 3 to adjust the coarseness of the ground powder. The bean grinding module 3 is connected to the powder discharge channel 5. The coffee powder ground by the cutting tools of the bean grinding module 3 falls through the powder discharge channel 5. A receiving container can be provided below the powder discharge channel 5 to receive the coffee powder falling from the powder discharge channel 5.

[0019] The anti-static device 6 includes a positive probe 61 and a negative probe 62, which are arranged on both sides of the outside of the powder outlet 51 of the powder outlet hopper 5. The air between the positive probe 61 and the negative probe 62 is ionized to remove the static electricity of the powder outlet 51. At least one of the positive probe 61 and the negative probe 62 extends a distance along the axial direction of the powder outlet 51. Alternatively, at least one of the positive probe 61 and the negative probe 62 extends a distance along the direction intersecting with the axial direction of the powder outlet 51, and the axial direction of the powder outlet 51 is as shown in FIG. Figure 3 The vertical arrow X is shown. The anti-static device 6 also includes a baffle 63, and the baffle 63 includes an opening 631 corresponding to the powder outlet 51. An internal accommodating space 7 is formed between the baffle 63 and the outer side of the powder outlet 51, and the positive probe 61 and the negative probe 62 are arranged in the internal accommodating space 7. Since the positive probe 61 and the negative probe 62 both extend beyond the end of the powder outlet 51, the anti-static function can be achieved within a certain distance from the powder outlet 51, and the anti-powder sticking effect is good. The setting of the baffle 63 can prevent the user from touching the positive probe 61 or the negative probe 62, which may cause injury to the user.

[0020] In this embodiment, the opening 631 of the baffle 63 is spaced apart from the distal end of the powder outlet 51 along the axial direction of the powder outlet 51. The positive probe 61 and the negative probe 62 both extend beyond the distal end of the powder outlet 51. Extending beyond the distal end of the powder outlet 51 prevents coffee powder from being electrostatically charged and then adhering to the outside of the powder outlet 51, thereby preventing the powder from flying.

[0021] The anti-static device 6 includes a first fixing frame 64 and a second fixing frame 65 . The first fixing frame 64 and the second fixing frame 65 are arranged on the baffle plate 63 of the grinder. The negative probe 62 is arranged on the first fixing frame 64 , and the positive probe 61 is arranged on the second fixing frame 65 .

[0022] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
