Description

Technical Field

[0001] Some embodiments of this utility model relate to a coffee grinder, and specifically design a negative ion generator and a coffee grinder. Background Technology

[0002] Portable coffee grinders are portable devices that grind coffee beans into coffee powder. Because of their small size and portability, users can enjoy freshly ground coffee anytime, anywhere.

[0003] Furthermore, current coffee grinders generate static electricity due to friction between the inner and outer blades of the grinding assembly and the coffee beans during grinding. This static electricity causes some coffee powder to adhere to the walls of the inner and outer blades. As a result, after the grinder finishes grinding the coffee beans, the amount of coffee powder in the coffee cup is much less than the amount of beans added, which affects the concentration of the coffee powder during extraction and the final taste of the coffee. Utility Model Content

[0004] The purpose of this invention is to design a negative ion generator and a coffee grinder, which can effectively prevent coffee powder from adsorbing onto the grinding component due to static electricity after the grinding component has finished grinding. This ensures that the quality of coffee powder held in the coffee cup is basically consistent with the quality of the coffee beans added, thereby guaranteeing the concentration of coffee powder during extraction and ensuring the taste of the coffee after brewing.

[0005] To achieve the above objectives, some embodiments of this utility model provide a negative ion generator, which is disposed on the main housing of a coffee grinder and located above the grinder's powder container. The negative ion generator includes:

[0006] The generator body has an emitter that can generate negative ions into the coffee grinder's powder container, the emitter acting on the powder container;

[0007] An electrical connection component is disposed on the generator body and electrically connected to the main control module of the grinder. It is used to transmit the electrical energy generated by the main control module to the generator body, causing the emitter of the generator body to discharge and generate electrons that enter the powder cup.

[0008] In addition, some embodiments of this utility model also provide a coffee grinder, including:

[0009] Main unit casing;

[0010] The coffee grinding assembly is disposed inside the main unit housing along a preset axial direction;

[0011] A coffee powder cup is disposed at the bottom of the main housing along the preset axis and is used to receive coffee powder produced by the grinding assembly when grinding coffee beans; wherein, the side of the grinding assembly relative to the coffee powder cup is the powder dispensing side;

[0012] A connector, located at the bottom of the main housing, is used to detachably connect the powder cup and is used to be passed through the powder outlet side of the grinding assembly, such that the powder outlet side is located above the powder cup;

[0013] The negative ion generator as described above;

[0014] The main control module is electrically connected to the electrical connection component of the negative ion generator and is used to supply power to the negative ion generator.

[0015] Compared to the prior art, the embodiments of this utility model have an advantage in that the negative ion generator is located on the main housing of the coffee grinder and above the coffee caddy. After the coffee grinder finishes grinding the coffee beans, the main control module of the coffee grinder can supply power to the negative ion generator, allowing the emitter of the negative ion generator to continuously discharge and generate electrons that enter the coffee caddy. These electrons can quickly transfer to the coffee powder adsorbed on the grinding components, allowing the coffee powder on the grinding components to quickly fall into the coffee caddy. This ensures that the quality of the coffee powder held in the coffee caddy is basically consistent with the quality of the coffee beans fed in, thereby improving the concentration of the coffee powder during extraction and ensuring the taste of the coffee after brewing.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0024] Example 1

[0025] The first embodiment of this utility model relates to a negative ion generating device, such as... Figure 2 As shown, the negative ion generator 5 is mounted on the main housing 2 of the coffee grinder and positioned above the grinder's powder container 3. Furthermore, combined with... Figure 5 As shown, the negative ion generator 5 includes a generator body 51 and an electrical connection assembly 52. ​​The generator body 51 has an emitter 511 that can generate negative ions into the coffee grinder's powder container 3, and this emitter 511 can act within the powder container 3. Secondly, as... Figure 2 As shown, the electrical connection component 52 is disposed on the generator body 51, and the electrical connection component 52 is also electrically connected to the main control module 6 of the grinder. At the same time, the electrical connection component 52 is also used to transmit the electrical energy generated by the main control module 6 to the generator body 51, so that the emitter 511 of the generator body 51 discharges and generates electrons that enter the powder cup 3.

[0026] As can be seen from the above, since the negative ion generator 5 is located on the main housing 2 of the coffee grinder and above the coffee powder cup 3, after the coffee grinder finishes grinding the coffee beans, the main control module 6 of the coffee grinder can supply power to the negative ion generator 5, so that the emitter 511 of the negative ion generator 5 can continuously discharge and generate electrons that enter the coffee powder cup 3. These electrons can quickly transfer to the coffee powder adsorbed on the grinding component 4, so that the coffee powder on the grinding component 4 can quickly fall into the coffee powder cup 3. This ensures that the quality of the coffee powder held in the coffee powder cup 3 is basically consistent with the quality of the coffee beans, thereby improving the concentration of coffee powder during extraction and ensuring the taste of coffee after brewing.

[0027] Specifically, in some embodiments, such as Figure 4 and Figure 5As shown, the generator body 51 includes a head housing 512 and a flange portion 513. The head housing 512 is disposed within the main housing 2 of the grinder, and at least partially passes through the connector 1 connecting the main housing 2 and the powder cup 3. The flange portion 513 is formed by a portion of the head housing 512 protruding circumferentially, and is used for detachable connection with the main housing 2. An emitter 511 is disposed within the head housing 512 and is electrically connected to the electrical connection assembly 52. ​​It is evident that the detachable connection between the flange portion 513 and the main housing 2 allows the head housing 512 to be stably fixed within the main housing 2, for example, as... Figure 5 As shown, connecting holes 515 can be provided on the flange portion 513, and each connecting hole 515 can cooperate with threaded locking parts such as bolts, thereby locking the head shell 512 into the main body housing 2. Of course, in other embodiments, the head shell 512 and the main body housing 2 can also be connected in other ways, such as by a snap-fit ​​connection. However, in this embodiment, the connection method between the head shell 512 and the main body housing 2 is not specifically limited. In addition, in order to enable the emitter 511 to discharge under the power supply of the main control module 6, in some embodiments, the emitter 511 can be made of carbon material. Of course, in other embodiments, the emitter 511 can also be made of stainless steel, or it can be made of composite material with metal plating or other alloy materials. However, in this embodiment, the material of the emitter 511 is not specifically limited.

[0028] Additionally, it is worth noting that in some other embodiments, such as Figure 5 As shown, the head shell 512 includes, along a predetermined axis, an insertion portion 5121 passing through the connector 1 and a clamping portion 5122 connected to the insertion portion 5121. Wherein, as... Figure 5 As shown, the flange portion 513 is partially protruding from the clamping portion 5122 around its circumference, and the radial width of the clamping portion 5122 is greater than the radial width of the insertion portion 5121, so that the clamping portion 5122 can abut against the connector 1, thereby ensuring that the head shell 512 can be stably fixed inside the main body shell 2. Furthermore, as a preferred embodiment, in other embodiments, such as... Figure 2 and Figure 5As shown, the negative ion generator 5 also includes a sealing ring 53, which is fitted onto the insertion part 5121 and positioned between the pressing part 5122 and the connecting member 1. This allows for a flexible seal between the pressing part 5122 and the connecting member 1, effectively preventing coffee powder collected in the powder cup 3 from overflowing into the main unit housing 2. It should be noted that the sealing ring 53 mentioned in the above embodiment can be a rubber sealing ring or a silicone sealing ring. A flexible seal between the pressing part 5122 and the connecting member 1 can be achieved using a rubber or silicone sealing ring. Of course, in other embodiments, the sealing ring can also be made of other materials. However, in this embodiment, the type of sealing ring 53 is not specifically limited.

[0029] Additionally, it is worth mentioning that, in order to further improve the sealing performance between the head shell 512 and the connector 1, in some other embodiments, such as Figure 4 and Figure 5 As shown, the insertion portion 5121 of the head shell 512 is interference-fitted with the connector 1. This interference fit further improves the sealing performance between the head shell 512 and the connector 1. Of course, in other embodiments, the insertion portion 5121 and the connector 1 can also employ other fitting methods. For example, the head shell 512 as a whole can be a flexible component, so that when the insertion portion 5121 is inserted into the connector 1, the insertion portion 5121 and the connector 1 can have a flexible abutment fit, thus similarly improving the sealing performance between the head shell 512 and the connector 1.

[0030] Additionally, in order to enable the main control module 6 of the coffee grinder to supply power to the emitter 511 of the negative ion generator 5, in some other embodiments, such as Figure 2 and Figure 5As shown, the electrical connection assembly 52 includes a first electrical connector 521 and a second electrical connector 522. The first electrical connector 521 is electrically connected to both the emitter 511 and the positive terminal of the main control module 6. Simultaneously, the second electrical connector 522 is electrically connected to both the emitter 511 and the negative terminal of the main control module 6. This allows the emitter 511 of the generator body 51 to be connected in series with the main control module 6 via the first and second electrical connectors 521 and 522. Therefore, after the grinder finishes grinding the coffee beans, the main control module 6 can supply power to the emitter 511 through the first and second electrical connectors 521 and 522 according to the current command, enabling the emitter 511 to continuously discharge and generate electrons that enter the powder cup 3. Furthermore, the first and second electrical connectors 521 and 522 mentioned in the above embodiment need to be flexible connectors such as copper wire or iron wire, thus allowing the negative ion generator 5 to be installed in any part of the main housing 2. Of course, it should be noted that in other embodiments, the first connector 521 and the second electrical connector 522 may also be electrical connector posts, such as copper posts, iron posts, etc. However, in this embodiment, the shape of the first electrical connector 521 and the second electrical connector 522 is not specifically limited.

[0031] Example 2

[0032] Embodiment 2 of this utility model relates to a coffee grinder, such as... Figure 1 , Figure 3 and Figure 6 As shown, it includes: main unit housing 2, grinding assembly 4, powder cup 3, connector 1, main control module 6, and negative ion generator 5 as described in Embodiment 1.

[0033] Among them, such as Figure 2 and Figure 7 As shown, the grinding component 4 is disposed within the main housing 2 along a preset axial direction, and the grinding component 4 has a powder outlet side 41. Furthermore, as... Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, the coffee caddy 3 is positioned at the bottom of the main housing 2 along a predetermined axis. This coffee caddy 3 is used to collect the coffee powder produced by the grinding assembly 4 during coffee bean grinding. Furthermore, the side of the grinding assembly 4 opposite the coffee caddy is the coffee powder dispensing side 41. Finally, as... Figure 2 As shown, connector 1 is located at the bottom of main housing 2. Connector 1 is used to detachably connect to powder cup 3 and is passed through by powder outlet side 41 of grinding assembly 4, so that powder outlet side 41 is located above powder cup 3.

[0034] Furthermore, it is not difficult to see from the above embodiment 1 that since the negative ion generator 5 is set on the main body housing 2, and the emitter 511 of the negative ion generator 5 is electrically connected to the main control module 6 through the electrical connection component 52, the main control module 6 can supply power to the emitter 511 after the grinder finishes grinding the coffee beans. At this time, the emitter 511 of the generator body 51 begins to discharge and can generate electrons that enter the powder cup 3. These electrons can quickly transfer to the coffee powder adsorbed on the grinding component 4, so that the coffee powder on the grinding component 4 can quickly fall into the powder cup 3, ensuring that the quality of the coffee powder held in the powder cup 3 is basically consistent with the quality of the beans, thereby improving the concentration of coffee powder during extraction and ensuring the taste of coffee after brewing. Furthermore, it is worth noting that, in order to enable the main control module 6 to supply power to the emitter 511 of the negative ion generator 5 via the electrical connection component 52, the main control module 6 integrates a negative ion generating submodule. In practical applications, the positive electrode of the negative ion generating submodule can be electrically connected to the first electrical connector 521 of the electrical connection component 52, and the negative electrode of the negative ion generating submodule can be electrically connected to the second electrical connector 522 of the electrical connection component 52. This allows the current generated by the negative ion generating submodule during operation to be delivered to the emitter 511 of the negative ion generator 5, thereby achieving the discharge of the emitter 511.

[0035] Additionally, it is worth mentioning that in some embodiments, such as Figure 5 As shown, the connector 1 is also provided with a mounting hole 13, which is used for the generator body 51 to pass through, so that the electrons generated by the discharge of the emitter 511 can smoothly enter the powder cup 3. Specifically, in some embodiments, such as Figure 7 As shown, connector 1 is an annular component, and connector 1 includes: a partition 11 and a connecting ring 12, wherein the partition 11 is disposed at the bottom of the main housing 2 and connected to the bottom of the main housing 2, and the partition 11 is used to separate the main housing 2 and the powder cup 3. Furthermore, as... Figure 7 As shown, the partition 11 includes: an inner side 112 forming the powder outlet 111, an upper surface 113 facing the main housing 2, and a lower surface 114 facing the powder cup 3. The powder outlet side 41 of the grinding assembly 4 also passes through the powder outlet 111, so that the powder outlet side 41 and the powder cup 3 are opposite to each other, so as to ensure that the powder cup 3 can receive the coffee powder discharged from the powder outlet side 41.

[0036] In addition, such as Figure 7 As shown, the connecting ring 12 is arranged circumferentially around the partition 11, and the connecting ring 12 is also connected to the partition 11. Secondly, in conjunction with... Figure 7As shown, the connecting ring 12 protrudes from the upper surface 113 of the partition 11 to form an upper edge 121, and this upper edge 121 surrounds an upper mounting area 115 on the upper surface 113 of the partition 11. This upper mounting area 115 is used to mount the main unit housing 2. Meanwhile, as... Figure 7 As shown, the connecting ring 12 also protrudes from the lower surface 114 of the partition 11 to form a lower edge 122, and the lower edge 122 surrounds the lower surface 114 of the partition 11 to form a lower mounting area 116, which is used to detachably connect the powder cup 3.

[0037] Furthermore, after the grinding assembly 4 finishes grinding the coffee powder, to further prevent the coffee powder from adhering to the grinding assembly 4 due to static electricity, as a preferred solution in some embodiments, the connector 1 should have certain conductive properties. Specifically, the connector 1 can be a conductive component, such as a metal component made of materials like iron, aluminum, or copper. It is easy to see that since the connector 1 is a conductive component, after the grinder finishes grinding the coffee beans, the user can touch the connector 1 to conduct the charge generated by the coffee powder during grinding through the connector 1 and the human body to the ground, thereby eliminating static electricity on the coffee powder. This allows the coffee powder adhering to the grinding assembly 4 to fall smoothly into the coffee cup 3, ensuring the consistency of the quality of the coffee powder held in the coffee cup 3 with the quality of the added beans, and further improving the concentration of the coffee powder during extraction, thus ensuring the taste of the brewed coffee. Furthermore, it should be noted that the connector 1 mentioned in the above embodiments is only described using a metal component as an example. In other embodiments, in order to ensure the conductivity of the connector 1, the connector 1 can also be made of carbon-based or silicon-based materials. However, in this embodiment, the material type of the connector 1 is not specifically limited.

[0038] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
