[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] As shown in the figure, the utility model provides an embodiment, which is a razor.

[0028] The shaver comprises an upper cover 2, an outer shell 1 and an inner shell 3, wherein the inner shell is a complete structure capable of realizing a shaving function, and the inner shell can be detachably installed into the outer shell, and the cutter head part thereof is covered by the upper cover, thereby realizing a complete shaver.

[0029] The outer shell and upper cover do not affect the normal operation of the inner tank.

[0030] An installation space is formed between the shell and the upper cover for fixing the inner shell. The shell and the upper cover can be made of the same material or different materials, such as plastic, soft rubber, metal, wood, glass, ceramic, etc. The surface of the shell and the upper cover can be sprayed with patterns, colors, etc. The shell and the upper cover can also have different shapes. Through the replaceable design, one or both of the shell and the upper cover can be replaced to make the shaver present different styles.

[0031] At the same time, the biggest advantage of replacing the outer shell is to achieve diverse processes for a single model, thereby reducing production waste and reducing consumers' after-sales replacement costs: if the inner liner is broken, replace the inner liner; if the outer shell is broken, replace the outer shell.

[0032] An inner pad 21 is provided in the upper cover 2, and a receiving space for receiving a first magnetic component 22 is formed between the inner pad and the upper cover. The inner pad is directly embedded in the upper cover, and a receiving space is formed between its upper surface and the inner wall of the upper cover. A magnetic component is provided in the receiving space, and the magnetic component can be directly magnetically adsorbed to the cutter head, making it easier to disassemble the upper cover.

[0033] The inner liner is detachably arranged in the space formed by the upper cover and the outer shell, and has a body 31 and a cutter head 32 detachably connected to the body, and the body is completely or partially placed in the outer shell, the cutter head is covered by the upper cover, and a locking mechanism is provided between the body and the outer shell.

[0034] The cutter head and the body are detachably connected by magnetic attraction. The cutter head and the body are connected by magnetic attraction, and disassembly is relatively convenient. Magnetic parts are provided in both the cutter head and the body, and the two are fixed by mutual adsorption.

[0035] The body includes a gear rack 311, a motor rack 312 and an inner shell 313, wherein a first space 314 for accommodating a gear set is formed between the gear rack and the upper end of the motor rack, the motor rack is placed in the inner shell, and the lower end of the motor rack is configured as a second space 315 for accommodating a motor and a battery, and a third space 316 for accommodating a circuit board is formed between the bottom of the motor rack and the inner shell.

[0036] A motor 4 is arranged at the central axis of the lower end of the motor frame, and mounting grooves opening to both sides are provided on both sides of the motor. A battery 5 is fixedly arranged in one of the mounting grooves, and the groove width of the mounting groove is slightly smaller than the diameter of the battery, so that the battery can extend into the mounting groove from the bottom and be confined therein, and the mounting groove can also be a hole-shaped structure, and the other side is reserved for placing another battery or a counterweight block to balance its weight and provide a better feel.

[0037] A plurality of buckles for fixing the circuit board are provided at the bottom of the motor frame, and the circuit board is placed horizontally at the bottom of the motor frame and seals the loading entrance of the second space, that is, the circuit board is placed horizontally at the bottom of the motor frame and constitutes a limit in the up and down directions, and the circuit board is used to fix the motor and the battery.

[0038] The charging port and control switch on the circuit board are arranged downward, so that the operating ends are at the bottom, thus not affecting the assembly of the inner tank.

[0039] The gear frame and the motor frame are snap-fitted together, and the motor frame and the inner shell are snap-fitted together, and the three are snap-fitted together to realize the integrated design of the fuselage, while eliminating the need for screw fixing, reducing costs, and making disassembly more convenient.

[0040] A charging interface and a control switch are provided on the circuit board, and the charging interface and the control switch are arranged perpendicular to the circuit board. A first opening adapted to the charging interface and the control switch is provided at the bottom of the inner shell, and the charging interface and the control switch are exposed through the first opening. A sealing structure is provided at the first opening to achieve a fully sealed setting of the inner shell to prevent dust from entering there.

[0041] The bottom of the shell is provided with a second opening corresponding to the first opening, and the second opening is used for operation after the shell is installed.

[0042] The locking mechanism is a screw, and the screw fixation can ensure that the outer shell is always connected to the inner shell.

[0043] At the same time, the locking mechanism can also be an interference fit between the inner shell and the outer shell.

[0044] At the same time, the locking mechanism can also be fixed in a buckle manner.

[0045] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
