Description

Technical Field

[0001] The present invention relates to the technical field of shaving, and in particular to a body assembly and a shaver. Background Art

[0002] In the prior art, electric shavers are generally provided with a switch button for starting or shutting down the product, and the switch button is arranged on the body; users generally start or shut down the product by pressing the switch by hand, and the switch is prone to mechanical fatigue after long-term use, which leads to switch failure and reduces the service life of the product; in addition, when the user washes the product after use, external water can easily enter the body through the gap between the switch button and the body, which can easily cause short circuit and damage of electronic components inside the body; another alternative is to design the switch button to be waterproof, which will result in numerous parts and complicated production. Utility Model Content

[0003] In order to overcome the problems existing in the related art, this specification provides a body assembly and a shaver.

[0004] According to the first aspect of the embodiments of this specification, a body assembly is provided, the body assembly comprising: a driving assembly for controlling the operation of a cutter head assembly; a shell, the driving assembly is arranged in the shell, and a contact hole is arranged on the shell; a conductive assembly electrically connects the driving assembly and the cutter head assembly; the conductive assembly comprises a contact member, the contact member is conductive, and the contact member extends to the contact hole; when a limb touches the contact member, the contact member is used to trigger the start of the driving assembly and the cutter head assembly. By detecting the impedance difference of the contact member when there is or is not contact with a conductor, the driving assembly will perform different processing according to the received signal, and judge whether the cutter head assembly is started according to the situation, and the impedance of the contact member can change when there is limb contact, without deformation or displacement, so as to avoid the problem of starting or shutting down the product by pressing the switch by the limb, causing mechanical fatigue of the switch and thus causing the switch to fail, reducing the service life of the product, and improving the service life of the product.

[0005] Furthermore, the fuselage assembly includes a bracket, the drive assembly includes a power storage element, the bracket is located inside the shell and is fixedly connected to the shell; the inner wall of the shell is provided with a first fixing member, the bracket includes a second fixing member, and the first fixing member and the second fixing member are connected by a clamping connection; the bracket is provided with a groove on one side close to the contact hole, the power storage element and the conductive component are at least partially arranged in the groove, and the power storage element is fixed to the bracket. A bracket is fixed inside the shell, and on the one hand, the bracket can be clamped with the inner wall of the shell to prevent the shell from collapsing inwards, and on the other hand, the bracket can be used to fix internal structures such as the power storage element and / or the conductive component to prevent them from moving around inside the shell.

[0006] Furthermore, the conductive component includes a drive circuit, the bracket divides the internal space of the shell into a first space area and a second space area, the first space area is a space close to the contact hole, the drive circuit is arranged in the first space area and fixed to the bracket; the contact piece includes an elastic part and a contact part; the contact part is fixed to the contact hole, one end of the elastic part abuts the contact part, and the other end is fixed to the drive circuit and electrically connected to the drive circuit; and the contact piece is compressed. The length of the contact piece before installation is greater than the distance from the contact piece installation surface to the inner wall of the shell, so the contact piece will remain in a compressed state after installation. When the contact piece is in a compressed state but the contact piece includes an elastic part with elasticity, the elastic part is compressed after installation, driving the contact part to abut against the switch, which can play a certain clamping role.

[0007] Furthermore, the diameter of the end of the elastic part close to the contact part is less than or equal to the diameter of the contact part, and is greater than the diameter of the end of the elastic part away from the contact part; when the contact piece is compressed, the contact area between the elastic part and the contact part is greater than the contact area between the elastic part and the contact part when the contact piece is not compressed. The contact piece is a densely wound spiral coil, and the projection size of the elastic part on the contact part decreases in the direction away from the contact part. Specifically, when compressed, the contact area between the elastic part and the contact part will increase due to the increase in the number of turns of its spiral contact surface, and the limb only needs to contact the trigger area on the contact part to trigger the drive assembly to drive the blade assembly. The trigger area is the projection area of ​​the contact area between the contact part and the elastic part on the surface of the contact part away from the elastic part. By using elasticity to increase the area of ​​the trigger area, the ratio of the area of ​​the trigger area to the surface area of ​​the contact part away from the elastic part is increased, thereby increasing the probability of triggering when the limb touches the surface of the contact part away from the elastic part, making the product's switch trigger more sensitive and accurate.

[0008] Furthermore, the driving circuit is provided with a controller, and the controller is electrically connected to the elastic part to obtain impedance information; the controller is also electrically connected to the driving component, and the controller is used to send a trigger signal to the driving component according to the impedance information; or, the driving circuit is electrically connected to the driving component, and the driving circuit is electrically connected to the elastic part to obtain impedance information, and the driving circuit sends a trigger signal to the driving component according to the impedance information, and the circuit between the power storage element and the driving component is connected. The driving circuit changes the original pressing or toggling type to a more lossless touch type by directly detecting the impedance of the elastic part or indirectly detecting the impedance of the elastic part through the controller, thereby reducing the mechanical loss of the switch element, extending the product life, and reducing the maintenance cost of the product.

[0009] Furthermore, the driving assembly includes a driving motor, and the number of the driving motors is two; the output end of the driving motor is connected to the cutter head assembly, and the cutter head assembly includes two independent cutter heads, and one driving motor controls one cutter head; the bracket divides the internal space of the shell into a first space area and a second space area along a first direction, and the driving motor is fixed on the bracket, and the connection direction of the two driving motors is a second direction, and the first direction is perpendicular to the second direction. The two driving motors drive the two cutter heads of the cutter head assembly respectively, and drive / stop the cutter head operation after receiving the trigger signal, so as to realize the separate operation of the two cutter heads and improve the working stability.

[0010] Further, the bracket includes a first part and a second part, an opening is provided in the shell, the second part of the bracket enters the shell through the opening, the first part covers the opening, and forms a receiving space with the shell; the second part of the bracket is used to divide the receiving space into a first space area and a second space area; the first space is close to the contact hole, and the contact member is provided in the first space area; the surface of the shell facing the second space area is the first surface, the surface of the second part facing the second space area is the second surface, and the first surface and the second surface are at least partially abutted. The first part and the second part are connected as one body, wherein the first part is above the second part, the cross-sectional area of ​​the first part in the vertical direction is larger than the cross-sectional area of ​​the second part in the vertical direction, the first part is used to cooperate with the opening at the top of the shell, and the second part is used to be installed inside the shell, and the first part and the shell surround to form a receiving space, which can be used to accommodate the internal components of the shaver.

[0011] Furthermore, a third fixing member is provided on the first surface, and a fourth fixing member is provided on the second surface. The third fixing member is one of the grooves or convex strips, and the fourth fixing member is the other of the grooves or convex strips. The third fixing member can be fixed by snapping with the fourth fixing member. After the bracket is installed into the shell, the third fixing member and the fourth fixing member fix the bracket in the shell through the matching relationship between the grooves and the convex strips, and the matching mode of the grooves and the convex strips can also provide the bracket with the determination of the installation direction during the installation process, reduce the difficulty of installation, and improve the accuracy of installation.

[0012] Furthermore, the height of the highest point of the third fixing member is lower than the height of the opening. The height of the third fixing member is lower than the height of the opening, that is, when the third fixing member is a groove, the groove is not connected to the top of the opening, and when the third fixing member is a convex strip, a gap is provided between the highest point of the third fixing member and the height of the opening, so as not to affect the fixation after the bracket completely enters the shell.

[0023] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this specification. Instead, they are merely examples of devices and methods consistent with some aspects of this specification as detailed in the appended claims.

[0024] The first aspect of the present application provides a fuselage assembly 1, such as Figure 1-Figure 2 The body assembly 1 shown includes a driving assembly 10, a shell 12 and a conductive assembly 11. The driving assembly 10 is used to control the operation of the cutter head assembly 2. The driving assembly 10 is arranged in the shell 12. The shell 12 is provided with a contact hole 20 that penetrates through. The conductive assembly 11 electrically connects the driving assembly 10 and the cutter head assembly 2. The shell 12 wraps the conductive assembly 11 and the driving assembly 10. The conductive assembly 11 outputs a trigger signal to the driving assembly 10. After receiving the trigger signal, the driving assembly 10 drives the cutter head assembly 2, and the shaver starts to operate. The conductive assembly 11 includes a contact member 30. The contact member 30 is conductive and extends to the contact hole 20. The contact member 30 is used to trigger and start the driving assembly 10 and the cutter head assembly 2. The conductive assembly 11 outputs a trigger signal when it detects that the impedance of the contact member 30 changes. When a limb touches the contact member 30, the impedance of the contact member 30 changes because the limb is also a conductor. By detecting the impedance difference of the contact piece 30 when there is contact with a conductor or not, the drive component 10 will perform different processing according to the received signal and determine whether the blade assembly 2 is started according to the situation. The impedance of the contact piece 30 can change when there is physical contact without deformation or displacement. This can avoid the problem of starting or closing the product by pressing the switch with physical force, causing mechanical fatigue of the switch and thus causing switch failure, thereby reducing the service life of the product and improving the service life of the product.

[0025] The body assembly 1 includes a bracket 13, and the drive assembly 10 includes a power storage element 40. The bracket 13 is located inside the shell 12 and is fixedly connected to the shell 12. The inner wall of the shell 12 is provided with a first fixing member 21, and the bracket 13 includes a second fixing member 50. The first fixing member 21 and the second fixing member 50 are connected by a clamping connection. The bracket 13 is provided with a groove on one side close to the contact hole 20, and the power storage element 40 and the conductive component 11 are at least partially arranged in the groove, and the power storage element 40 is fixed to the bracket 13. The bracket 13 is fixed inside the shell 12. On the one hand, the bracket 13 can be connected with the inner wall of the shell 12 to prevent the shell 12 from collapsing inwards. On the other hand, the bracket 13 can be used to fix the internal structures such as the power storage element 40 and the conductive component 11 to prevent them from moving around inside the shell 12.

[0026] The conductive component 11 includes a drive circuit 31, and the bracket 13 divides the internal space of the housing 12 into a first space area 22 and a second space area 23. The first space area 22 is a space close to the contact hole 20. The drive circuit 31 is arranged in the first space area 22 and fixed to the bracket 13; the contact member 30 includes an elastic portion 32 and a contact portion 33; the contact portion 33 is fixed to the contact hole 20, one end of the elastic portion 32 abuts against the contact portion 33, and the other end is fixed on the drive circuit 31 and electrically connected to the drive circuit 31; and the contact member 30 is compressed. The length of the contact member 30 before installation is greater than the distance from the installation surface of the contact member 30 to the inner wall of the housing 12, so the contact member 30 will remain in a compressed state after installation. When the contact member 30 is in a compressed state but the contact member 30 includes an elastic elastic portion 32 with elasticity, the elastic portion 32 is compressed after installation, driving the contact portion 33 to abut against the switch, which can play a certain clamping role.

[0027] The diameter of the end of the elastic part 32 close to the contact part 33 is less than or equal to the diameter of the contact part 33, and is larger than the diameter of the end of the elastic part 32 away from the contact part 33; when the contact member 30 is compressed, the contact area between the elastic part 32 and the contact part 33 is larger than the contact area between the elastic part 32 and the contact part 33 when the contact member 30 is not compressed. The contact member 30 is a densely wound spiral coil, and the projection size of the elastic part 32 on the contact part 33 decreases in the direction away from the contact part 33. Specifically, when compressed, the contact area between the elastic part 32 and the contact part 33 increases due to the increase in the number of turns of its spiral contact surface, and the limb only needs to contact the trigger area on the contact part 33 to trigger the drive assembly 10 to drive the cutter head assembly 2. The trigger area is the projection area of ​​the contact area between the contact part 33 and the elastic part 32 on the surface of the contact part 33 away from the elastic part 32. By utilizing elasticity to increase the trigger area, the ratio of the trigger area to the surface area of ​​the contact portion 33 away from the elastic portion 32 is increased, thereby increasing the trigger probability when the limb touches the surface of the contact portion 33 away from the elastic portion 32, making the product's switch trigger more sensitive and accurate.

[0028] The driving circuit 31 is provided with a controller 34, and the controller 34 is electrically connected to the elastic part 32 to obtain impedance information; the controller 34 is also electrically connected to the driving component 10, and the controller 34 is used to send a trigger signal to the driving component 10 according to the impedance information; or, the driving circuit 31 is electrically connected to the driving component 10, and the driving circuit 31 is electrically connected to the elastic part 32 to obtain impedance information, and the driving circuit 31 sends a trigger signal to the driving component 10 according to the impedance information, and the circuit between the power storage element 40 and the driving component 10 is connected. The driving circuit 31 changes the original pressing or toggling type to a more lossless touch type by directly detecting the impedance of the elastic part 32 or indirectly detecting the impedance of the elastic part 32 through the controller 34, thereby reducing the mechanical loss of the switch element, extending the product life, and reducing the maintenance cost of the product.

[0029] The driving assembly 10 includes a driving motor 28, and the number of the driving motors 28 is two; the output end of the driving motor 28 is connected to the cutter head assembly 2, and the cutter head assembly 2 includes two independent cutter heads, and one driving motor 28 controls one cutter head; the bracket 13 divides the internal space of the housing 12 into a first space area 22 and a second space area 23 along a first direction X, and the driving motor 28 is fixed on the bracket 13, and the connection direction of the two driving motors 28 is a second direction Y, and the first direction X is perpendicular to the second direction Y. The two driving motors 28 drive the two cutter heads of the cutter head assembly 2 respectively, and drive / stop the cutter head operation after receiving the trigger signal, so as to realize the separate operation of the two cutter heads and improve the working stability.

[0030] like Figure 3 As shown, the bracket 13 includes a first part 41 and a second part 42, an opening 24 is provided in the shell 12, the second part 42 of the bracket 13 enters the shell 12 through the opening 24, the first part 41 covers the opening 24, and forms a receiving space 25 with the shell 12; the second part 42 of the bracket 13 is used to divide the receiving space 25 into a first space area 22 and a second space area 23; the first space is close to the contact hole 20, and the contact member 30 is arranged in the first space area 22; the surface of the shell 12 facing the second space area 23 is the first surface 26, the surface of the second part 42 facing the second space area 23 is the second surface 43, and the first surface 26 and the second surface 43 are at least partially abutted. The first part 41 and the second part 42 are integrally connected, wherein the first part 41 is above the second part 42, and the cross-sectional area of ​​the first part 41 in the vertical direction is larger than the cross-sectional area of ​​the second part 42 in the vertical direction. The first part 41 is used to cooperate with the opening 24 at the top of the shell 12, and the second part 42 is used to be installed inside the shell 12. The first part 41 and the shell 12 surround and form a accommodating space 25, which can be used to accommodate internal components of the shaver.

After the bracket 13 is installed into the housing 12, the third fixing member 27 and the fourth fixing member 44 fix the bracket 13 in the housing 12 through the matching relationship between the grooves and the convex strips, and the matching mode of the grooves and the convex strips can also provide the bracket 13 with the determination of the installation direction during the installation process, thereby reducing the difficulty of installation and improving the accuracy of installation.
