DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] See also Figure 1 and Figure 2The embodiment of the present application provides an electric shaver 10, including a body 100, a head cover assembly 200, a start-stop controller 300 and a drive assembly 400, the head cover assembly 200 includes a blade mesh cover 210 and a blade head 220 arranged inside the blade mesh cover 210, the blade mesh cover 210 is arranged on the body 100, the start-stop controller 300 and the drive assembly 400 are arranged inside the body 100, and the start-stop controller 300 is connected to the drive assembly 400 and can be conducted with the blade mesh cover 210, and is used to control the drive assembly 400 to open when a change in the electrical signal carried by the blade mesh cover 210 is detected, so as to drive the blade head 220 to work, or control the drive assembly 400 to close so as to stop the blade head 220 from working.

[0041] Through the above arrangement, when a human body is close to or away from the knife net cover 210, since the human body itself carries a certain amount of electrical capacitance, the electrical signal detected by the start-stop controller 300 will change, and then according to the change, the drive component 400 is controlled to be turned on to drive the knife head 220 to work, or the drive component 400 is controlled to be closed to stop the knife head 220 from working. The change of the electrical signal mainly refers to the change of electrical capacitance. For example, when a human body is close to the knife net cover 210, the electrical capacitance detected by the start-stop controller 300 increases, and the drive component 400 is controlled to be turned on to drive the knife head 220 to work. When the user moves away from the blade mesh cover 210, the capacitance detected by the start-stop controller 300 decreases, and the drive assembly 400 is controlled to be turned off to stop the blade head 220 from working, thereby achieving the purpose of the invention that the user brings the blade mesh cover 210 of the electric shaver 10 close to the target area, and the electric shaver 10 can be automatically turned on, and the user moves the blade mesh cover 210 of the electric shaver 10 away from the target area, and the electric shaver 10 can be automatically turned off, which greatly enhances the convenience of using the electric shaver 10. The target area can be any area of ​​the human body such as the face, head, legs, etc. where beards or hair need to be shaved.

[0042] Please combine Figure 3In the embodiment of the present application, the knife net cover 210 can drive the knife head 220 to be closed or opened relative to the body 100, and when the knife net cover 210 is closed relative to the body 100, the driving component 400 cooperates with the knife head 220, and when the knife net cover 210 is opened relative to the body 100, the driving component 400 is away from the knife head 220. Based on this, in order to prevent the user from accidentally touching the blade mesh cover 210 and causing the electric shaver 10 to automatically turn on when the blade mesh cover 210 is opened relative to the body 100 so that the drive component 400 is away from the blade head 220, in an embodiment of the present application, the electric shaver 10 may further include a guide component 500, which is connected to the start-stop controller 300, and when the blade mesh cover 210 is closed relative to the body 100, the guide component 500 is connected to the blade mesh cover 210 so that the start-stop controller 300 is connected to the blade mesh cover 210, and when the blade mesh cover 210 is opened relative to the body 100, the guide component 500 is disconnected from the blade mesh cover 210 so that the start-stop controller 300 is disconnected from the blade mesh cover 210.

[0043] Furthermore, please combine Figures 4 to 7 In the embodiment of the present application, the driving assembly 400 includes a motor 410 and a transmission shaft assembly 420. The motor 410 is arranged inside the fuselage 100, connected to the start-stop controller 300, and connected to the transmission shaft assembly 420 through a motor shaft 411. The fuselage 100 includes a working end surface 110 of the knife net cover 210 for setting the working end surface 110 of the knife net cover 210, and a driving connection hole is provided on the working end surface 110. The transmission shaft assembly 420 is arranged on the working end surface 110 of the fuselage 100 through the driving connection hole. When the knife net cover 210 is closed relative to the fuselage 100, the transmission shaft assembly 420 cooperates with the knife head 220. When the knife net cover 210 is opened relative to the fuselage 100, the transmission shaft assembly 420 is away from the knife net cover 210. It should be noted that, in the embodiment of the present application, one or more transmission shaft assemblies 420 may be provided, and the specific number shall be determined according to the number of the cutter heads 220 provided. However, it can be understood that when one transmission shaft assembly 420 is provided, the motor 410 may be directly connected to the transmission shaft assembly 420 via the motor shaft 411; and when multiple transmission shaft assemblies 420 are provided, the motor 410 may control the rotation of the driving gear 600 via the motor shaft 411, and the driving gear 600 is meshed with multiple driven gears 700, and each driven gear 700 has a unique correspondingly connected transmission shaft assembly 420.

[0044] Based on the above settings, in an embodiment of the present application, if the transmission shaft assembly 420 is made of a conductive material, the guide assembly 500 can be connected to the start-stop controller 300 and the transmission shaft assembly 420 respectively, so that when the knife net cover 210 is closed relative to the fuselage 100 and the transmission shaft assembly 420 is matched with the knife head 220, the start-stop controller 300 is connected to the knife net cover 210 through the guide assembly 500, the transmission shaft assembly 420 and the knife head 220 in sequence; and when the knife net cover 210 is opened relative to the fuselage 100 and the transmission shaft assembly 420 is away from the knife head 220, it is disconnected from the knife head 220 and indirectly disconnected from the knife net cover 210, so that the start-stop controller 300 is disconnected from the knife net cover 210.

Therefore, even if the user accidentally touches the blade mesh cover 210, the electric shaver 10 will not automatically turn on, thereby enhancing the safety of the electric shaver 10. However, it should be noted that if the guide assembly 500 is opened relative to the body 100 and the user accidentally touches the part of the transmission shaft assembly 420 located outside the body 100 for cooperating with the blade head 220, the electric shaver 10 will still automatically turn on.

[0048] Furthermore, in an embodiment of the present application, the conduction control component 540 can be arranged on the body 100 and located at the end where the knife mesh cover 210 is provided, and the conduction connection component 530 may include a second conductive sheet 531 and a second conductive wire 532, the second conductive sheet 531 is located at the end of the conduction control component 540 away from the knife mesh cover 210, and the second conductive wire 532 is respectively connected to the start-stop controller 300 and the second conductive sheet 531. In addition, to facilitate the setting of the conduction control component 540, in an embodiment of the present application, a control connection hole can also be provided on the working end surface 110 of the fuselage 100, and the conduction control component 540 can include a connector 541 and a control component 542, wherein the connector 541 is provided on the working end surface 110 of the fuselage 100 through the control connection hole, and the first end of the connector 541 is located inside the fuselage 100, and the second end of the connector 541 is located outside the fuselage 100, and the control component 542 is provided on the connector 541, so that when the knife net cover 210 is closed relative to the fuselage 100, the control connector 541 is respectively connected to the knife net cover 210 and the conduction connection component 530, and when the knife net cover 210 is opened relative to the fuselage 100, the control connector 541 is away from the knife net cover 210 and is disconnected from the conduction connection component 530, so that the start-stop controller 300 is disconnected from the knife net cover 210.

The second controller 340 can also be a general-purpose processor, for example, it can be a digital signal processor (Digital Signal Processor, DSP), an application-specific integrated circuit (Application Specific Integrated Circuit, ASIC), a discrete gate or transistor logic device, a discrete hardware component, and in addition, the general-purpose processor can be a microprocessor or any conventional processor.

[0055] In the embodiment of the present application, the signal generator 320 is used to generate an initial AC signal and transmit the initial AC signal to the conductor member 330. The second controller 340 is used to collect the target AC signal output by the conductor member 330 after the initial AC signal is transmitted to the conductor member 330, and generate a sensing result based on the target AC signal to indicate whether the electrical signal carried on the knife net cover 210 changes, and control the drive component 400 to turn on to drive the cutter head 220 to work, or control the drive component 400 to turn off to stop the cutter head 220 from working, wherein controlling the drive component 400 to turn on can be to connect the drive component 400 to the power module 800, and controlling the drive component 400 to turn off can be to disconnect the drive component 400 from the power module 800.

[0056] In addition, the working principle of the start-stop controller 300 provided by the second optional implementation is that when the human body is away from the knife mesh cover 210, the target AC signal output by the conductor 330 is equivalent to the initial AC signal in strength, but when the human body is close to the knife mesh cover 210, since the human body carries a certain amount of capacitance, it will bypass the initial AC signal transmitted on the conductor 330, so that the conductor 330 outputs a target AC signal weaker than the initial AC signal. The second controller 340 can generate a sensing result according to the strength of the target AC signal to indicate whether the electrical signal carried by the knife mesh cover 210 has changed, and control the drive group The control driving component 400 is turned on to drive the cutter head 220 to work, or the control driving component 400 is turned off to stop the cutter head 220 from working. For example, when the intensity of the target AC signal is less than the preset intensity threshold, it indicates that the electrical signal carried by the knife mesh cover 210 has increased, and a first sensing result of controlling the driving component 400 to turn on is generated. When the intensity of the target AC signal is greater than or equal to the preset intensity threshold, it indicates that the electrical signal carried by the knife mesh cover 210 has not changed or has decreased, and a second sensing result indicating that the electrical signal carried by the knife mesh cover 210 has not changed or has decreased is generated, and the control driving component 400 is turned off to stop the cutter head 220 from working.

[0057] To sum up, the electric shaver 10 provided in the embodiment of the present application includes a body 100, a head cover assembly 200, a start-stop controller 300 and a drive assembly 400. The head cover assembly 200 includes a blade mesh cover 210 and a blade head 220 arranged inside the blade mesh cover 210. The blade mesh cover 210 is arranged on the body 100, and the start-stop controller 300 and the drive assembly 400 are arranged inside the body 100. The start-stop controller 300 is connected to the drive assembly 400 and can be conducted with the blade mesh cover 210. When a change in the electrical signal carried by the blade mesh cover 210 is detected, the drive assembly 400 is controlled to be turned on to drive the blade head 220 to work, or the drive assembly 400 is controlled to be turned off to stop the blade head 220 from working. In this way, when the human body is close to or away from the blade mesh cover 210, since the human body itself carries a certain amount of electrical capacitance, the electrical signal detected by the start-stop controller 300 will change. According to the change, the drive component 400 is controlled to be turned on to drive the blade head 220 to work, or the drive component 400 is controlled to be turned off to stop the blade head 220 from working. For example, when the human body is close to the blade mesh cover 210, the electrical capacitance detected by the start-stop controller 300 increases, and the drive component 400 is controlled to be turned on to drive the blade head 220 to work. When the human body is away from the blade mesh cover 210, the electrical capacitance detected by the start-stop controller 300 decreases, and the drive component 400 is controlled to be turned off to stop the blade head 220 from working. In this way, the user brings the blade mesh cover 210 of the electric razor 10 close to the target area, and the electric razor 10 can be automatically turned on. The user moves the blade mesh cover 210 of the electric razor 10 away from the target area, and the electric razor 10 can be automatically turned off. The convenience of using the electric razor 10 is greatly enhanced.
