[0028] Currently, the waterproofing of electric shavers on the market is not comprehensive enough. For example, the waterproofing of parts such as the pores in the cover plate, the motor, and the charging port is generally not waterproof, and they cannot achieve the effect of being fully washed.

[0029] Therefore, this utility model provides a waterproof razor. Figure 1-4 For an embodiment of the waterproof razor provided by this utility model, please refer to [link / reference]. Figure 1-4 The shaver 100 includes a head assembly 1, a drive assembly 2, and a housing 3.

[0030] The housing 3 includes a base 31 and a cover plate 32. The base 31 is approximately ellipsoidal in shape and has an installation space inside. The drive assembly 2 is disposed in the installation space. The end of the base 31 is opened to form an opening 31a. The cover plate 32 is engaged with the inner wall protrusion of the base 31 by a snap fastener on its outer edge and is installed at the opening 31a to facilitate encapsulation after the internal components are assembled.

[0031] Please see Figure 2 and 4 The outer periphery of the cover plate 32 extends in a direction perpendicular to the plate to form a raised wall 321, and a recessed platform is formed on one side of the cover plate 32. When the user performs a shaving action, the cut hair will fall onto this recessed platform. The cover plate 32 is provided with a magnetic component (not shown in the figure) for adsorbing and connecting with the blade assembly 1. When cleaning is required, the blade assembly 1 can be forcefully moved away to clean the cover plate 32 and the blade assembly 1.

[0032] Please see Figure 4 The cover plate 32 has two symmetrical through holes 32a perpendicular to the plate. The two driving ends 211 of the driving assembly 2 protrude outward from the through holes 32a of the cover plate 32 and are drivenly connected to the two rotatably arranged cutting heads 11 of the cutting head assembly 1. It should be understood that in other embodiments, the number of through holes 32a can be set to other numbers, such as one, three, etc., and the corresponding number of driving ends 211 and cutting heads 11 is also the same.

[0033] Specifically, please refer to Figure 4 An annular groove 322 is formed on the outer side of the protruding wall 321 of the cover plate 32. A first soft rubber 5 is fixedly installed in the annular groove 322, and the first soft rubber 5 is also interference-fitted with the inner side wall of the base 31 so that the connection between the cover plate 32 and the base 31 is sealed.

[0034] Additionally, a second soft rubber 6 is provided at the through hole 32a of the cover plate 32. The second soft rubber 6 and the through hole 32a are press-fitted to seal the connection between them. The part of the drive end 211 that passes through the through hole 32a is a shaft. This shaft can be connected to the second soft rubber 6 through and press-fitted with it so that the through hole 32a on the cover plate 32 is sealed.

[0035] In this technical solution, soft rubber is provided between the base 31 and the cover plate 32, and between the drive end 211 of the drive assembly 2 in the base 31 and the cover plate 32. When the user cleans the hair on the cover plate 32 with water, water is prevented from seeping in through the pores, thus achieving complete waterproofing of the drive assembly 2 and the base 31, preventing its components from being corroded or damaged by short circuits.

[0036] For better waterproofing of the pores in cover plate 32, please refer to [link / reference]. Figure 2 and 4 In one embodiment of this utility model, the first soft rubber 5 and the second soft rubber 6 are integrally molded, which facilitates installation and further improves the compactness of the seal. The second soft rubber 6 is disc-shaped, with its main body outline tightly fitted to the other side of the cover plate 32. A conical structure is formed at the center of the disc, and the shaft of the drive end 211 passes through the hole 6a of this conical structure, with the shaft surface and the hole 6a having an interference fit. This conical structure effectively prevents water from seeping into the machine base 31 through the hole 6a, reducing water settling.

[0037] Please see Figure 2 and 3 In one embodiment of this utility model, a frame 4 is installed inside the base 31, and the drive assembly 2 is fixed to the frame 4. To fix the frame 4, a screw hole 31b is provided at the bottom of the base 31, through which a bolt 33 can pass and be fixedly connected to the frame 4. The frame 4 may have internal threads or a nut to engage with the bolt 33. To waterproof the screw hole 31b, a third soft rubber 7 is provided between the bolt 33 and the screw hole 31b. The outline of the third soft rubber 7 is adapted to the surface of the base 31, achieving an effective seal. Simultaneously, the third soft rubber 7 acts as a sealing gasket and has an interference fit with the bolt 33. Preferably, the bolt 33 and the screw hole 31b are further sealed by a threaded connection.

[0038] Similar to most models on the market, the shaver 100 provided in this embodiment is rechargeable. Please refer to [link / reference]. Figure 2 In addition to the micro motor 21, the drive assembly 2 also includes a power supply 22 and a circuit board 23, which are electrically connected in sequence. To charge the power supply 22, the circuit board 23 is equipped with a charging head 231, and the housing 3 is correspondingly equipped with a charging interface 31c. The charging head 231 of the circuit board 23 is located inside the charging interface 31c. To prevent water from entering the gap between the charging head 231 and the charging interface 31c, a fourth soft adhesive 8 is provided between the outer wall of the charging head 231 and the inner wall of the charging interface 31c, and is press-fitted to it.

[0039] Please see Figure 2 and 3To control the opening and closing of the motor 21, the circuit board 23 is also equipped with a control switch, and the housing 3 is also equipped with a mounting hole 31d. The control switch is connected to the circuit board 23 and protrudes outward from the mounting hole 31d. A fifth soft rubber 9 is provided between the control switch and the mounting hole 31d. It should be noted that the control switch consists of a button 24 and a push-button switch 232 on the circuit board 23. The button 24 is located in the mounting hole 31d and protrudes outward. While the button 24 is connected inside the mounting hole 31d, it also has an interference fit with the fifth soft rubber 9, so that the gap between the mounting hole 31d and the button 24 is sealed. At the same time, the outer contour of the fifth soft rubber 9 is adapted to the surface of the base 31, which can achieve effective sealing.

[0040] Please see Figure 3 In a preferred embodiment, the third soft adhesive 7 and the fifth soft adhesive 9 are integrally molded, which facilitates installation and further enhances the compactness of the seal.

[0041] Additionally, since the one-piece molded third soft rubber 7 and fifth soft rubber 9 are partially exposed on the surface of the base 31, please refer to... Figure 1 In one embodiment of this utility model, a protective shell 34 is also provided around the outer periphery of the housing 3 to protect the lower part of the base 31 and prevent water from entering.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
