Description

Technical Field

[0001] The invention relates to a shaver, in particular to a reciprocating electric shaver. Background Art

[0002] Current razors are generally used to shave short beards, but not long beards. This is because the beard inlet of the razor cannot accommodate long beards. After a long period of design, the designer has also designed a razor head that can shave long beards, but the shell of the razor head cover and the blade net are integrally formed, such as the razor net, razor head and razor disclosed in application number 202323469161.9, which require relatively high processing technology and are relatively expensive. In order to ensure the fit between the razor head cover and the blade, the shapes of the two need to be processed exactly the same to ensure that the razor can shave the beard cleanly. However, this structure has strict requirements on the size of the components and is difficult to process. Summary of the invention

[0003] The present invention aims at solving the shortcomings of the prior art and provides a reciprocating electric shaver.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-8 The present invention is further described in detail with examples. Example

[0030] A reciprocating electric shaver includes a housing 10, a blade cover 11 and a blade 12. The blade 12 is mounted on the housing 10. The blade cover 11 covers the blade 12 and can be detachably mounted on the housing 10. The blade 12 includes a blade seat 121 and a blade 122 fixed on the blade seat 121. The blade cover 11 includes a plastic shell 111 and a metal blade net 112. The top of the shell 111 forms a tip 1111 with an acute angle. The tip 1111 is provided with a notch 1112. The blade net 112 is embedded in the notch 1112 of the tip 1111 and forms an integral body with the housing 111. The tops of the blade net 112 and the blade 122 are both provided with a number of beard inlet holes 100. The beard inlet holes 100 on the same component are connected and arranged to form a zigzag shape. The zigzag beard inlet holes 100 of the blade net 112 and the blade 122 can be used to inlet long beards, so that the shaver can shave long beards. The blade cover 11 is divided into two parts, and the blade net 112 is embedded in the shell 111, which simplifies the processing technology and saves processing costs. The traditional one-piece molded blade cover 11 needs to use micro-carving technology when processing the blade net, which is costly.

[0031] The projection shape of the side of the blade 122 is an inverted V shape. The blade 122 includes a fixing portion 1221 and a cutting portion 1222. The top of the blade 122 is bent to form the cutting portion 1222. The angle between the fixing portion 1221 and the cutting portion 1222 is an obtuse angle. This structural form allows the cutting portion 1222 of the blade 122 to be tightly attached to the knife net 112. The bending from the top reduces the friction surface with the knife net 112, thereby reducing friction resistance.

[0032] The casing 10 includes a shell 101, a top seat 102 and a metal shell 17. The metal shell 17 is wrapped around the shell 101 to improve the strength of the shaver casing. An annular groove 1021 is provided on the side wall of the lower end of the top seat 102. A sealing ring 13 is installed in the annular groove 1021. The top seat 102 is sealed at the port of the metal shell 17 by the sealing ring 13 to prevent water from entering between the metal shell 17 and the shell 101.

[0033] The top seat 102 includes a lower seat body 1021 and an upper seat body 1022 . The upper seat body 1022 is detachably mounted on the lower seat body 1021 . The lower seat body 1021 is integrally formed on the top of the shell 101 . The sealing ring 13 is mounted on the lower seat body 1021 .

[0034] A reciprocating linear motor 14 is installed at the upper end of the housing 101. The lever 141 of the linear motor 14 passes through the top seat 102 and is fixedly connected to the blade seat 121. The hole in the top seat 102 through which the lever 141 passes is the lever hole. The linear motor 14 works and drives the blade seat 121 to swing left and right. The blade seat 121 drives the blade 122 to cut the beard. The linear motor is a modular product that makes installation more efficient and also reduces the mechanical structure of the shaver that converts rotational power into linear motion. The shaft of the lever 141 is covered with a sealing sleeve 15. The lever 141 is sealed on the top seat 102 through the sealing sleeve 15 to prevent water from entering the housing 101 through the lever hole of the top seat 102, thereby improving the waterproofness of the shaver.

[0035] Elastic reset seats 1023 are provided on both sides of the upper end of the lower seat body 1021, and a retractable and movable elastic reset member 16 is installed in the elastic reset seat 1023. The elastic reset member 16 can lock the cutter head cover 11 on the cutter head 12. The elastic reset member 16 includes a spring and a limit head. The inner side wall of the cutter head cover 11 is provided with a slot 1113. When the cutter head cover 11 is installed on the top seat 102, the limit head of the elastic reset member 16 is engaged in the slot 1113.

[0036] The lower seat body 1021 is provided with a through hole 1024 for the lever 141 to move left and right, and the through hole 1024 is a waist-shaped through hole. The lower seat body 1021 is provided with a positioning sleeve 1025 integrally formed at the end of the through hole 1024. The sealing sleeve 15 is provided with a positioning groove 151, and the sealing sleeve 15 is installed on the positioning sleeve 1025 through the positioning groove 151. The upper seat body 1022 presses the positioning sleeve 1025 onto the positioning sleeve 1025. The sealing sleeve 15 has good stability on the top seat 102, and the sealing sleeve 15 will not easily fall off the top seat 102 when the lever 141 moves.

[0037] A button 18 is installed on the upper end of the metal shell 17, and an elastic membrane covering the button 18 is installed on the inner side of the metal shell 17. The elastic membrane improves the waterproofness and prevents water from entering the metal shell 17 through the button 18. A fixed block 1011 is integrally formed on the upper end of the shell 101, and a switch 19 is installed on the fixed block 1011. When the elastic button 18 touches the switch 19, the linear motor 14 is started.

[0038] A guide rod 103 protruding upward is fixed on the top seat 102, and the guide rod 103 is integrally formed on the upper seat body 1022. A guide hole 1210 penetrating the upper and lower end surfaces of the knife seat 121 is provided. The guide hole 1210 is long and the guide rod 103 extends into the guide hole 1210. The guide rod 103 is used to stabilize the knife head 12 to prevent the lower end of the knife head 12 from shaking back and forth when the knife head 12 moves left and right to cut beards, causing a gap between the blade 122 and the knife net 112.

[0039] The housing 101 is also provided with a battery 20 for supplying power to the linear motor 14. A stepped notch is provided at the lower end of the battery 20. A circuit board 21 for controlling the linear motor 14 is installed at the notch. The space utilization rate in the housing 101 is high, and the battery 20 can be made larger and have more power. The battery 20 is provided below the linear motor 14.
