[0021] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the present invention.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1 The present invention provides a grinding device 100, which includes a power supply base 10 and an electric grinder 20. The electric grinder 20 is detachably mounted on the power supply base 10. For example, when the electric grinder 20 needs to be charged, the electric grinder 20 can be mounted on the power supply base 10, so that the power supply base 10 can charge the electric grinder 20. For another example, after the electric grinder 20 is fully charged, the electric grinder 20 can be removed from the power supply base 10 for use.

[0024] The power supply base 10 includes a base circuit board 11 and a power indicator light 12, which are electrically connected. The electric grinder 20 includes a grinder circuit board 21 and a battery 22, which are electrically connected. When the electric grinder 20 is installed on the power supply base 10, the power supply circuit and the indicator light circuit between the electric grinder 20 and the power supply base 10 are electrically connected. The base circuit board 11 transmits electrical energy to the battery 22 via the power supply circuit, and the grinder circuit board 21 controls the power indicator light 12 to illuminate via the indicator light circuit.

[0025] Thus, when the electric grinder 20 is mounted on the power base 10, the power indicator light 12 illuminates, allowing the user to intuitively understand whether the device is charging, which helps improve user convenience and satisfaction. Furthermore, since the power indicator light 12 is controlled by the grinder circuit board 21, the circuit complexity of the base circuit board 11 is reduced, helping to reduce manufacturing costs and maintenance difficulties.

[0026] In some embodiments, the power supply base 10 further includes a first power supply electrical connector 13, a first indicator light electrical connector 14, and a first electrical connector 15, and the base circuit board 11 is electrically connected to the first power supply electrical connector 13, the first indicator light electrical connector 14, and the first electrical connector 15. The electric grinder 20 further includes a second power supply electrical connector 23, a second indicator light electrical connector 24, and a second electrical connector 25, and the grinder circuit board 21 is electrically connected to the second power supply electrical connector 23, the second indicator light electrical connector 24, and the second electrical connector 25.

[0027] When the electric grinder 20 is installed on the power supply base 10, the first power supply electrical connector 13 is electrically connected to the second power supply electrical connector 23 and is set in the power supply circuit, the first indicator light electrical connector 14 is electrically connected to the second indicator light electrical connector 24 and is set in the indicator light circuit, and the first electrical connector 15 is electrically connected to the second electrical connector 25 and conducts the power supply circuit and the indicator light circuit.

[0028] Thus, by providing the first and second power supply electrical connectors 23, the first and second indicator light electrical connectors 24, and the first and second electrical connectors 25, the connection between the base circuit board 11 and the grinder circuit board 21 is made more modular, which helps simplify the overall circuit design, reducing manufacturing costs and maintenance difficulties. The electrical contact between the first power supply electrical connector 13 and the second power supply electrical connector 23, the first indicator light electrical connector 14 and the second indicator light electrical connector 24, and the first electrical connector 15 and the second electrical connector 25 helps ensure the stability and reliability of the connection, thereby improving the efficiency of power transmission during the charging process. Furthermore, stable power transmission helps reduce damage to the battery 22 caused by unstable charging, thereby helping to extend the service life of the battery 22.

[0029] In some embodiments, the second power supply electrical connector 23 may serve as the positive electrode, the second indicator light electrical connector 24 may serve as the positive electrode, and the second electrical connector 25 may serve as the negative electrode.

[0030] In some embodiments, when the electric grinder 20 is removed from the power supply base 10, the first power supply electrical connector 13 and the second power supply electrical connector 23 are separated and the power supply circuit is disconnected, the first indicator light electrical connector 14 and the second indicator light electrical connector 24 are separated and the indicator light circuit is disconnected, and the first electrical connector 15 and the second electrical connector 25 are separated and the power supply circuit and the indicator light circuit are disconnected.

[0031] In this way, when the electric grinder 20 is removed from the power supply base 10, the power indicator light 12 will go out, and the user can intuitively understand that the device is no longer in the charging state, which helps to improve the user's operating convenience and satisfaction, and also helps to reduce unnecessary power consumption, thereby improving energy utilization efficiency.

[0032] In some embodiments, one of the first power supply electrical connector 13 and the second power supply electrical connector 23 is a spring probe and the other is a conductive sheet; and / or, one of the first indicator light electrical connector 14 and the second indicator light electrical connector 24 is a spring probe and the other is a conductive sheet; and / or, one of the first electrical connector 15 and the second electrical connector 25 is a spring probe and the other is a conductive sheet.

[0033] In this way, the use of a combination of a spring probe and a conductive sheet can ensure that when the electric grinder 20 is installed on the power supply base 10, the electrical connectors can be in close contact, which helps to improve the stability and reliability of the connection and reduce failures caused by poor contact. The design of the spring probe has a certain degree of elasticity, which can reduce the wear on the conductive sheet during multiple plugging and unplugging, and help to extend the service life of the electrical connector. The elastic properties of the spring probe can adapt to conductive sheets of different sizes and shapes, which helps to improve the versatility and adaptability of the connector and is suitable for a variety of different devices and application scenarios. The coordinated design of the spring probe and the conductive sheet makes the connection and disconnection between the electric grinder 20 and the power supply base 10 faster and more convenient, which helps to improve the user's efficiency and helps to reduce short circuits or electric sparks caused by poor contact, thereby providing a safer operating environment during the charging process. In addition, the combined design of the spring probe and the conductive sheet is relatively simple, which helps to simplify the circuit design of the base and the grinder, and reduce manufacturing costs and maintenance difficulties.

[0034] In some embodiments, the first power supply electrical connector 13, the first indicator light electrical connector 14, and the first electrical connector 15 are all electrically the same type of electrical connector. Using the same type of electrical connector simplifies the assembly process, reduces the possibility of assembly errors, and helps improve assembly efficiency and production speed. This helps simplify the manufacturing process of the power supply base 10, reduces the need for different types of parts, and thus reduces production costs.

[0035] In some embodiments, the second power supply electrical connector 23, the second indicator light electrical connector 24, and the second electrical connector 25 are all of the same type. Using the same type of electrical connector simplifies the assembly process, reduces the likelihood of assembly errors, and helps improve assembly efficiency and production speed. This helps simplify the manufacturing process of the electric grinder 20, reduces the need for different types of parts, and thus reduces production costs.

[0036] In some embodiments, the first electrical connector 15 is located between the first power supply electrical connector 13 and the first indicator light electrical connector 14. The second electrical connector 25 is located between the second power supply electrical connector 23 and the second indicator light electrical connector 24, with the second electrical connector 25 opposing the first electrical connector 15, the second power supply electrical connector 23 opposing the first power supply electrical connector 13, and the second indicator light electrical connector 24 opposing the first indicator light electrical connector 14.

[0037] In this way, the first electrical connector 15 and the second electrical connector 25 can jointly serve as the negative electrode for the power supply circuit and the indicator light circuit. This design helps simplify the circuit design of the base circuit board 11 and the grinder circuit board 21. This layout reduces the need for complex wiring, helps improve circuit reliability and maintainability, and thus helps reduce production costs and maintenance difficulties.

[0038] In some embodiments, the power supply base 10 further includes at least one isolating member 16, with at least one isolating member 16 positioned between and separating the first power supply connector 13 and the first electrical connector 15. This isolating member 16 helps physically isolate the first power supply connector 13 from the first electrical connector 15, reducing electrical interference between them. For example, it helps reduce the risk of a short circuit between the first power supply connector 13 and the first electrical connector 15 due to accumulated water or other conductive materials. This design helps improve the safety and reliability of the device in humid environments, thereby enhancing the overall performance of the device.

[0039] In some embodiments, multiple insulating members 16 are provided, with at least one insulating member 16 positioned between and separating the first indicator electrical connector 14 and the first electrical connector 15. This insulating member 16 helps physically isolate the first indicator electrical connector 14 from the first electrical connector 15, reducing electrical interference between them. For example, this helps mitigate the risk of short circuits between the first indicator electrical connector 14 and the first electrical connector 15 due to accumulated water or other conductive materials. This design helps improve the safety and reliability of the device in humid environments, thereby enhancing the overall performance of the device.

[0040] In some embodiments, the electric grinder 20 is further provided with at least two slots 26, at least one of which is located between the second power supply electrical connector 23 and the second electrical connector 25 and is provided for the insulating member 16 located between the first power supply electrical connector 13 and the first electrical connector 15 to be retained; and at least one of which is located between the second indicator light electrical connector 24 and the second electrical connector 25 and is provided for the insulating member 16 located between the first indicator light electrical connector 14 and the first electrical connector 15 to be retained.

[0041] In this way, the slot 26 provides a clear positioning point for the insulating member 16. By snapping the insulating member 16 into the slot 26, it helps to increase the mechanical bonding force between the electric grinder 20 and the power supply base 10, and helps to improve the contact accuracy between the electrical connectors, so that the user can simply place the electric grinder 20 on the power supply base 10 to achieve automatic alignment and power supply, and also helps to reduce the movement or shaking of the device during the charging process, thereby helping to maintain a stable and reliable electrical connection.

[0042] In some embodiments, the power supply base 10 is provided with a plurality of base grooves 17 , and the first electrical connector 15 , the first power supply electrical connector 13 and the first indicator light electrical connector 14 are respectively located in the corresponding base grooves 17 and exposed from the corresponding base grooves 17 to the power supply base 10 .

[0043] In this way, by arranging the electrical connector in the base groove 17, the electrical connector can be located at a lower position relative to the upper surface of the power supply base 10, which helps reduce the risk of external objects directly hitting the electrical connector, thereby helping to protect the electrical connector from physical damage.

[0044] In some embodiments, the base groove 17 may be substantially in the form of a circular groove, an elliptical groove, a triangular groove, a square groove, a polygonal groove, a special-shaped groove, or other shapes.

[0045] In this utility model, unless otherwise expressly specified or limited, terms such as "mounted," "connected," and "fixed" should be interpreted broadly. For example, these terms may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; internal communication between two components; surface contact only; or surface contact through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0046] In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as specific or special structures. The descriptions of the terms "some embodiments", "other embodiments", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.
