[0025] In order to enable those skilled in the art to better understand the solutions of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model.

[0027] Please refer to Figure 1 , an embodiment of the present utility model provides a power supply base 100, which can be applied to a grinding device 1000. For example, the power supply base 100 can supply power to an electric grinder 200. In other embodiments, the power supply base 100 can also supply power to other products.

[0028] Please refer to Figures 2 to 3 , the power supply base 100 includes a base housing 10, a first electrical connector 20, a second electrical connector 30, and an insulating member 40. The base housing 10 is provided with a first power supply part 11 and a second power supply part 12. The first electrical connector 20 and the second electrical connector 30 are spaced apart and arranged on the base housing 10. The first electrical connector 20 is exposed from the first power supply part 11 outside the base housing 10, and the second electrical connector 30 is exposed from the second power supply part 12 outside the base housing 10.

[0029] The insulating member 40 protrudes from the base housing 10. The insulating member 40 is located between the first power supply part 11 and the second power supply part 12, and spaces apart the first electrical connector 20 and the second electrical connector 30, so that the insulating member 40 can better isolate the first electrical connector 20 and the second electrical connector 30 in the physical space. Even if water drops on the first power supply part 11 and the second power supply part 12 during the charging process, it helps to reduce the situation of conduction between the first electrical connector 20 and the second electrical connector 30 due to the accumulated water, thereby helping to reduce the risk of short circuit and facilitating the application of the power supply base 100 in easily humid spaces such as kitchens and bathrooms.

[0030] In some embodiments, the base housing 10 includes an upper surface 13, a first side surface 14, and a second side surface 15. The upper surface 13 is connected between the first side surface 14 and the second side surface 15. Both the first power supply part 11 and the second power supply part 12 are arranged on the upper surface 13. One end of the insulating member 40 extends to the junction of the upper surface 13 and the first side surface 14, and the other end of the insulating member 40 extends to the junction of the upper surface 13 and the second side surface 15.

[0031] In this way, the design of the insulating member 40 extending from the upper surface 13 to the two side surfaces helps the insulating member 40 to form a more effective insulating continuous structure, which not only helps to reduce the risk of moisture or other liquids flowing along the edge of the base housing 10 to the first electrical connector 20 and the second electrical connector 30, but also helps to increase the firmness of the overall structure of the insulating member 40, thereby helping to improve the impact resistance of the power supply base 100 during use.

[0032] In some embodiments, the insulating member 40 and the base shell 10 are integrally formed, so that the insulating member 40 becomes a part of the structure of the base shell 10, which helps to reduce the number of parts of the power supply base 100, helps to make the overall appearance more neat and uniform, and helps to enhance the visual appeal of the product. Among them, the insulating member 40 and the base shell 10 can be integrally formed by a mold, and for example, the insulating member 40 and the base shell 10 can be injection molded. In other embodiments, the insulating member 40 and the base shell 10 can also be integrally formed by other methods.

[0033] In some embodiments, the first electrical connector 20 may be a conductive sheet.

[0034] In some embodiments, the first power supply part 11 is provided with a first groove 110, and the first electrical connector 20 is located in the first groove 110 and is exposed from the first groove 110 to the base housing 10. In this way, by arranging the first electrical connector 20 in the first groove 110, the first electrical connector 20 can be located at a lower position relative to the upper surface 13 of the base housing 10, which helps to reduce the risk of external objects directly hitting the first electrical connector 20, thereby helping to protect the first electrical connector 20 from physical damage.

[0035] In some embodiments, the first groove 110 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.

[0036] In some embodiments, the first groove 110 is spaced from the insulating member 40 , and the spacing distance between the first groove 110 and the insulating member 40 can serve as an additional barrier to help slow down the flow of moisture or other liquids from the first groove 110 to the insulating member 40 , thereby helping to improve the anti-short circuit performance of the power supply base 100 .

[0037] See also Figures 3 to 6 In some embodiments, a first carrier 16 is disposed in the first groove 110. The first electrical connector 20 includes a first conductor 21, a second conductor 22, and a first stopper 23, which are connected in sequence. The first conductor 21 is disposed on the first carrier 16 and is exposed from the first groove 110 to the base housing 10. The second conductor 22 extends from the first conductor 21 toward the base housing 10. The first stopper 23 abuts against a surface of the first carrier 16 that is away from the first conductor 21.

[0038] Thus, the first carrier 16 provides a stable support point for the first conductor 21 and, in cooperation with the first stopper 23, helps to limit the position of the first conductor 21. Since the first conductor 21 is supported by the first carrier 16 and has the first stopper 23 as a rear support, it helps to ensure that the position of the first conductor 21 remains fixed during the charging process, thereby helping to enhance the stability of the electrical connection of the entire power supply base 100. In addition, the design of the second conductor 22 extending into the base housing 10 helps to hide the electrical connection part, helps to reduce the impact of external factors (such as moisture, dust, etc.) on it, and helps to protect the internal circuit from damage.

[0039] In some embodiments, the first electrical connector 20 is an integrally formed structure. Thus, it helps to reduce the number of parts of the first electrical connector 20, helps to improve the mechanical strength of the first electrical connector 20, and helps to ensure a stable and reliable electrical connection every time charging occurs.

[0040] In some embodiments, the second power supply part 12 is provided with a second groove 120. The second electrical connector 30 is located in the second groove 120 and is exposed from the second groove 120 to the base housing 10. Thus, by arranging the second electrical connector 30 in the second groove 120, the second electrical connector 30 can be positioned at a lower level relative to the upper surface 13 of the base housing 10. This helps to reduce the risk of an external object directly hitting the second electrical connector 30, thereby helping to protect the second electrical connector 30 from physical damage.

[0041] In some embodiments, the second groove 120 can generally be in the shape of a circular groove, an oval groove, a triangular groove, a square groove, a polygonal groove, a special-shaped groove, or other shapes.

[0042] In some embodiments, the second groove 120 is spaced from the isolator 40. Then, the spacing distance between the second groove 120 and the isolator 40 can serve as an additional barrier, helping to slow down the flow of moisture or other liquids from the second groove 120 to the isolator 40, and helping to improve the short-circuit prevention performance of the power supply base 100.

[0043] In some embodiments, the second electrical connector 30 can be a conductive sheet.

[0044] In some embodiments, a second carrier 17 is disposed in the second groove 120. The second electrical connector 30 includes a third conductor 31, a fourth conductor 32, and a second stopper 33, which are connected in sequence. The third conductor 31 is disposed on the second carrier 17 and is exposed from the second groove 120 to the base housing 10. The fourth conductor 32 extends from the third conductor 31 toward the inside of the base housing 10. The second stopper 33 abuts against a surface of the second carrier 17 that is away from the third conductor 31.

[0045] In this way, the second support platform 17 provides a stable support point for the third conductor 31, and cooperates with the second limiter 33 to help limit the position of the third conductor 31. Since the third conductor 31 is supported by the second support platform 17 and has the second limiter 33 as a rear support, it helps to ensure that the position of the third conductor 31 remains unchanged during the charging process, thereby helping to enhance the stability of the electrical connection of the entire power supply base 100. In addition, the design of the fourth conductor 32 extending into the base shell 10 helps to hide the electrical connection part, helps to reduce the impact of external factors (such as water vapor, dust, etc.) on it, and helps to protect the internal circuit from damage.

[0046] In some embodiments, the second electrical connector 30 is an integrally formed structure, which helps reduce the number of parts of the second electrical connector 30, helps improve the mechanical strength of the second electrical connector 30, and helps ensure that a stable and reliable electrical connection is formed each time charging.

[0047] In some embodiments, the first electrical connector 20 may serve as a positive electrode and the second electrical connector 30 may serve as a negative electrode.

[0048] An embodiment of the utility model provides a grinding device 1000, which includes a power supply base 100 of any of the above-mentioned embodiments and an electric grinder 200, wherein the electric grinder 200 includes a third electrical connector 201 and a fourth electrical connector 202. When the electric grinder 200 is placed on the power supply base 100, the third electrical connector 201 is electrically connected to the first electrical connector 20, and the fourth electrical connector 202 is electrically connected to the second electrical connector 30.

[0049] In some embodiments, the third electrical connector 201 and the fourth electrical connector 202 may both be spring probes.

[0050] In some embodiments, the third electrical connector 201 may serve as a negative electrode, and the fourth electrical connector 202 may serve as a positive electrode.

[0051] In some embodiments, the electric grinder 200 is further provided with a card slot 203. The card slot 203 is located between the third electrical connector 201 and the fourth electrical connector 202, and the isolator 40 is clamped in the card slot 203. In this way, the card slot 203 provides a definite positioning point for the isolator 40. By clamping the isolator 40 into the card slot 203, it helps to increase the mechanical bonding force between the electric grinder 200 and the power supply base 100, helps to improve the contact precision between the electrical connectors, so that it helps the user to simply place the electric grinder 200 on the power supply base 100 to achieve automatic alignment and power supply. And it also helps to reduce the movement or shaking of the device during the charging process, thus helping to maintain a stable and reliable electrical connection.

[0052] In some embodiments, the number of the electric grinders 200 can be one or more. Correspondingly, the number of the structures (such as the first power supply part 11, the second power supply part 12, the first electrical connector 20, the second electrical connector 30, the isolator 40, etc.) in the power supply base 100 that match the electric grinder 200 can also be one or more, and the number of the above-mentioned matching structures of the power supply base 100 can be the same as the number of the electric grinders 200.
