Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a waterproof and dustproof grinding charging base and grinding components. Background Technology

[0002] Currently, most rechargeable grinders on the market (such as pepper grinders, coffee grinders, and sea salt grinders) have their charging ports located at the discharge end. During the grinding process, pepper, coffee, and sea salt powders inevitably leave residue. This residue can easily seep into the charging port, causing corrosion and poor charging contact. In severe cases, it can even cause the charging components to rust and corrode, affecting the grinder's normal use and lifespan. Furthermore, given that these grinders are primarily used in kitchens, where the environment is humid and frequently wet, if the charging port on the base gets wet, it can easily cause a short circuit, posing a serious safety hazard and threatening the user's personal safety and property. Utility Model Content

[0005] This utility model discloses a waterproof and dustproof grinding tool charging base, comprising an upper cover plate and a lower cover plate, which are detachably connected. The upper cover plate has several seats, each with a cavity in the center for holding a grinding tool. Two charging holes are symmetrically arranged on one side of the top wall of each seat. Two lower conductive silicone heads are symmetrically arranged inside the lower cover plate, each with a lower conductive spring connected to its bottom end and connected to a charging circuit board. The lower conductive silicone heads are correspondingly positioned and extend into the corresponding charging holes. The bottom of the grinding tool has symmetrically arranged downward-extending upper conductive silicone heads, each with a top end connected to an upper conductive spring connected to a battery. When the upper and lower conductive silicone heads are correspondingly positioned and in contact with each other, the grinding tool can be charged.

[0006] Furthermore, a positioning groove is provided on the other side of the top wall of the base, and an LED light is provided at the bottom of the grinder, with the LED light corresponding to the positioning groove.

[0007] Furthermore, the LED light is a hemisphere, and the positioning groove is a semi-waist-shaped groove.

[0008] Furthermore, the bottom of the upper cover plate is symmetrically provided with a number of positioning posts, and the upper part of the lower cover plate is correspondingly provided with a number of positioning seats, and the positioning posts are inserted into the corresponding positioning seats.

[0009] Furthermore, the lower conductive silicone head has a stepped cylindrical structure.

[0010] Furthermore, the bottom of the lower cover plate is provided with several anti-slip pads.

[0011] This utility model also provides a grinder assembly, which adopts the aforementioned waterproof and dustproof grinder charging base and includes a grinder. The bottom of the grinder is provided with a base plate, and a mating end is provided at the center of the bottom of the base plate. The mating end extends into the receiving cavity.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] This utility model discloses a waterproof and dustproof grinder charging base and grinder assembly. By incorporating a conductive silicone structure at the charging interface, the conductive silicone, with its excellent elasticity, ensures a tight seal between the lower conductive silicone head and the charging hole on the upper cover when no grinder is placed, effectively preventing the intrusion of external dust and moisture, thus providing waterproofing and dustproofing. When the grinder is placed on the charging base, the upper and lower conductive silicone heads contact and press downwards under the grinder's own weight, achieving a stable and reliable conductive connection and ensuring smooth charging. Furthermore, due to the insulating properties of the conductive silicone surface, even if accidentally exposed to water during daily use, it will not cause a short circuit due to conductivity, unlike traditional metal gaskets, further ensuring safety.

[0033] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figures 1 to 5As shown, the waterproof and dustproof grinder charging base 1 of this embodiment 1 includes an upper cover plate 11 and a lower cover plate 12. The upper cover plate 11 and the lower cover plate 12 are detachably connected for easy assembly and maintenance. Several seats 13 are provided on the upper cover plate 11. Each seat 13 has a receiving cavity 14 in the middle to accommodate the grinder 2. This arrangement allows multiple grinders 2 to be charged simultaneously, improving charging efficiency. Two charging holes 16 are symmetrically opened on one side of the top wall of the seat 13. Two lower conductive silicone heads 17 are symmetrically arranged inside the lower cover plate 12. The bottom end of the lower conductive silicone head 17 is connected to a lower conductive spring 18, which is connected to the charging circuit board. The lower conductive silicone head 17 is correspondingly arranged with the charging hole 16 and extends into the corresponding charging hole 16 for docking with the upper conductive silicone head 24 at the bottom of the grinder 2 to realize the charging function.

[0036] Furthermore, the bottom of the grinder 2 is symmetrically provided with downwardly extending upper conductive silicone heads 24. The top of the upper conductive silicone head 24 is connected to the upper conductive spring 26, which is connected to the battery. The upper conductive silicone head 24 and the lower conductive silicone head 17 are correspondingly arranged and in contact with each other, so that the grinder 2 can be charged.

[0037] At this time, when the grinder 2 is placed in the receiving cavity 14, its upper conductive silicone head 24 and lower conductive silicone head 17 make corresponding contact to form a conductive path. The charging circuit board transfers electrical energy to the battery of the grinder 2 through the lower conductive spring 18 and the lower conductive silicone head 17 to realize the charging function.

[0038] Specifically, a positioning groove 15 is provided on the other side of the top wall of the base 13, and an LED light 23 is provided at the bottom of the grinder 2. The LED light 23 is set in correspondence with the positioning groove 15, that is, the shape and size of the positioning groove 15 match the LED light 23 at the bottom of the grinder 2. This effectively ensures that the grinder 2 can be accurately aligned with the lower conductive silicone head 17 during charging without repeated adjustments. Furthermore, the close cooperation between the positioning groove 15 and the LED light 23 enhances the stability of the grinder 2 during the charging process, preventing the grinder 2 from slipping or shifting due to external interference. This not only protects the grinder 2 and the charging base 1 from damage, but also ensures the smooth progress of the charging process.

[0039] Preferably, the LED light 23 is a hemisphere and the positioning groove 15 is a semi-waist-shaped groove. The shape of the hemisphere allows the LED light 23 to be naturally guided and aligned when inserted into the positioning groove 15, reducing the difficulty of user operation.

[0040] The upper cover plate 11 has several symmetrically arranged positioning posts at its bottom, and the lower cover plate 12 has several corresponding positioning seats on its upper part. The positioning posts are inserted into the corresponding positioning seats. The cooperation between the positioning posts and the positioning seats makes the upper cover plate 11 and the lower cover plate 12 more stable when connected, and it is not easy for them to move or deform relative to each other. This improves the overall structural stability of the charging base 1 and ensures its reliability and durability during long-term use.

[0041] Preferably, the lower conductive silicone head 17 has a stepped cylindrical structure. The stepped cylindrical structure of the lower conductive silicone head 17 can ensure close contact with the charging hole 16 and effectively prevent external dust, moisture and other substances from entering the charging hole 16.

[0042] In addition, several anti-slip pads 3 are provided at the bottom of the lower cover plate 12, which can increase the friction between the charging base 1 and the placement surface and prevent the charging base 1 from sliding due to accidental contact or uneven ground during use.

[0043] The waterproof and dustproof grinder charging base 1 of this embodiment 1 incorporates a conductive silicone structure at the charging interface. Due to the excellent elasticity of the conductive silicone, when the grinder 2 is not placed on it, the lower conductive silicone head 17 fits tightly against the charging hole 16 on the upper cover plate 11, forming a reliable sealing structure that effectively prevents external dust and moisture from intruding, thus providing waterproof and dustproof protection. When the grinder 2 is placed on the charging base 1, under the weight of the grinder 2 itself, the upper conductive silicone head 24 contacts the lower conductive silicone head 17 and presses downwards, achieving a stable and reliable conductive connection and ensuring smooth charging. Furthermore, due to the insulating properties of the conductive silicone surface, even if it accidentally gets wet during daily use, it will not cause a short circuit due to conductivity like traditional metal gaskets, further ensuring safety during use.

[0044] In this embodiment 1, conductive silicone is a prior art technology and will not be described in detail here.

[0045] Example 2

[0046] like Figures 6 to 11 As shown, the grinder assembly of this embodiment 2 adopts the waterproof and dustproof grinder charging base 1, and also includes a grinder 2. The bottom of the grinder 2 is provided with a base plate 21, and a mating end 22 is provided at the center of the bottom of the base plate 21. The mating end 22 extends into the receiving cavity 14 to achieve preliminary positioning. A mating hole is symmetrically provided on one side of the base plate 21, and an upper conductive silicone head 24 is mated and connected in the mating hole.

[0047] Specifically, an LED light 23 is provided on the other side of the base plate 21, and a positioning groove 15 is provided on the other side of the base body 13. The LED light 23 and the positioning groove 15 are correspondingly set. The two work together to ensure that the grinder 2 can be quickly and accurately aligned with the position on the charging base 1 when placed, avoiding the risk of poor charging or charging interruption due to inaccurate positioning.

[0048] Furthermore, a limiting plate 27 is fixedly connected to the upper part of the base plate 21, and a conductive limiting seat 25 is connected to the top of the upper conductive silicone head 24. The conductive limiting seat 25 is fixed inside the limiting plate 27, and the top of the conductive limiting seat 25 is connected to the upper conductive spring 26.

[0049] Preferably, the upper conductive silicone head 24 is frustum-shaped.

[0050] This utility model discloses a waterproof and dustproof grinding tool charging base and grinding tool assembly. By incorporating a conductive silicone structure at the charging port, it effectively prevents external dust and moisture from entering the charging port. Even if accidentally exposed to water during daily use, it will not cause short circuits due to conductivity, unlike traditional metal pads, thus ensuring safe use. This utility model features a reasonable overall structural design, is easy to use, and highly practical.

[0051] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
