SPECIFIC EMBODIMENTS

(8) This invention is described further as follows by reference to the attached drawings and specific embodiments.

(9) As shown in FIG. 1 and FIG. 6, which are the overall structural diagram and overall exploded view of the electric grinder, the electric grinder provided in this embodiment comprises a shell 1, wherein said shell 1 accommodates a grinding mechanism 2, a reducing mechanism 3 and a power mechanism 4, and also comprises a grinding chamber 5, where said grinding mechanism 2 is set at one end of said grinding chamber 5, and said power mechanism 4 and said reducing mechanism 3 are set at the other end of said grinding chamber 5. During use, pepper particles and sea salt particles etc. are loaded into the electric grinder, and the grinding mechanism 2 is driven by the power mechanism 4 and the reducing mechanism 3 to implement the automatic grinding function of the electric grinder.

(10) In further combination with FIG. 2, said grinding chamber 5 is provided with a filling hole 6, and a chamber cover 7 provided opposite to said filling hole 6, and the filling hole 6 of said grinding chamber 5 can be opened or closed by turning said chamber cover 7. The filling hole 6 can be easily opened or closed by turning the turnable chamber cover 7, which is easy and convenient to operate. After the chamber cover 7 rotates and closes the filling hole 6 of the grinding chamber 5, the grinding chamber 5 will be well sealed and no pepper particles or sea salt particles will flow out easily from the filling hole 6.

(11) As a selected embodiment, referring to FIG. 3, said chamber cover 7 is provided with a snap 71, and said chamber cover 7 is detachably connected to said grinding chamber 5 through the snap 71. When it is necessary to seal the grinding chamber 5, the chamber cover 7 is easily fastened onto the filling hole 6 of the grinding chamber 5 through the snap 71. There may be two said snaps 71, which are mounted symmetrically on said chamber cover 7.

(12) As shown in FIG. 2 and FIG. 5, in order to fit the chamber cover 7 closely at the filling hole 6 of the grinding chamber 5, said filling hole 6 is provided with a limiting part 61, where said limiting part 61 is mounted at the inner edge of said filling hole 6. Such design can ensure that after the bottom of the chamber cover 7 extends into the filling hole 6 on the grinding chamber 5, the snap 71 on said chamber cover 7 can be interlocked with the limiting part 61 on the grinding chamber 5, and the chamber cover 7 will not easily fall out of the filling hole 6 on the grinding chamber 5.

(13) With further reference to FIG. 2, a notch 62 is provided on said limiting part 61, where said notch 62 has a width greater than the width of said snap 71. There are two said notches 62, which are mounted symmetrically on said limiting part 61. When the snap 71 of the chamber cover 7 is aligned with the notch 62 of the limiting part 61, the bottom of the chamber cover 7 can extend into the grinding chamber 5 and cover the filling hole 6 of the grinding chamber 5, and the snap 71 of the chamber cover 7 is fastened on the limiting part 61 of the grinding chamber 5 by turning the chamber cover 7 further to ensure that the chamber cover 7 will not fall off from the filling hole 6 of the grinding chamber 5.

(14) With reference to FIG. 5 and FIG. 6, said limiting part 61 is further provided with a slot 63 on the side facing the inside of said grinding chamber 5, said slot 63 is connected to said notch 62, and said slot 63 fits with said snap 71. Such design will ensure that the snap 71 will be housed in the slot 63 after the chamber cover 7 is turned further when the snap 71 is aligned with the notch 62 of the limiting part 61, and extended into the grinding chamber 5 from the notch 62. The slot 63 could hold the snap 71 to prevent the chamber cover 7 from moving, and thus improve the closing stability between the chamber cover 7 and the filling hole 6.

(15) With further reference to FIG. 3 and FIG. 4, said snap 71 is provided with a recess 72 on the side wall, said slot 63 is provided with a projection 64 on the side wall, and said recess 72 fits with said projection 64. Such design will ensure that the recess 72 on the snap 71 is fastened on the projection 64 in the slot 63 when the snap 71 is housed in the slot 63 by turning the chamber cover 7, which further holds the chamber cover 7 to prevent the chamber cover 7 from moving and close the chamber cover 7 tighter.

(16) Specifically, said projection 64 is an arc-shaped block, said recess 72 is an arc-shaped slot, and said snap 71 is provided with an arc-shaped portion at the end first in contact with said projection 64, which reduces the resistance of the projection 64 to the snap 71 and facilitates turning the chamber cover 7 to align the recess 72 with the projection 64.

(17) With reference to FIG. 3 and FIG. 5, said chamber cover 7 comprises an annular edge 73, and said snap 71 and said annular edge 73 are spaced apart to snap on said limiting part 61 on the inner and outer sides. When the chamber cover 7 is closed at the filling hole 6, the annular edge 73 of the chamber cover 7 leans against the outer side of the limiting part 61, while the snap 71 is housed in the slot 63 on the inner side of the limiting part 61. In this way, the chamber cover 7 will be held in the inner and outer directions, which will ensure that the chamber cover 7 will not fall off from the filling hole 6 of the grinding chamber 5.

(18) The rotating handle 74 is mounted above the chamber cover 7, and the chamber cover 7 can be rotated by turning the rotating handle 74, where the rotating handle 74 can be a solid structure or a hollow structure. Such design makes it easier to remove the chamber 7 from the filling chamber.

(19) As a selected embodiment, please refer to FIG. 4 and FIG. 5 in which a transmission shaft 8 is mounted in said grinding chamber 5, where one end of said transmission shaft 8 is connected to said reducing mechanism 3, and the other end of said transmission shaft 8 is connected to said grinding mechanism 2. The shell 1 is further provided with a battery pack 9, where said battery pack 9 is electrically connected to said power mechanism 4.

(20) The electric grinder provided in this invention is so designed that the filling hole 6 of the grinding chamber 5 can be easily opened or closed by turning the chamber cover 7, which is easy and convenient to operate. After the chamber cover 7 rotates and closes the filling hole 6 of the grinding chamber 5, the grinding chamber 5 will be well sealed and no material will flow out easily, and the chamber cover 7 will not fall off easily.
