The control chip <NUM> is simultaneously connected to the driving component <NUM>, the handle induction element <NUM> and the head portion induction element <NUM>, and the driving component <NUM> is also connected to the cutter head <NUM>, so that the driving component <NUM> drives the cutter head <NUM> to work under the control of the control chip <NUM>. It should be noted that the control chip <NUM> is also the controller, since the control chip <NUM> may control the cutter head <NUM> to start and stop, the control chip <NUM> may also be called a start-stop controller in some embodiments.

The first electric shaver <NUM> is a beard clipper, and the structure of the electric shaver <NUM> is described in detail below by taking the first electric shaver <NUM> as an example.

Specifically, the handle induction element <NUM> may also be called a second sensor, the head portion induction element <NUM> may also be called a first sensor, simultaneously, the handle induction element <NUM> and the head portion induction element <NUM> may be collectively called as an induction assembly, in other words, the electric shaver <NUM> includes the induction assembly, and the induction assembly comprises the handle induction element <NUM> and the head portion induction element <NUM>. The handle induction element <NUM> is configured to detect whether the electric shaver <NUM> is in the state of being held by the operator, when the handle induction element <NUM> detects that the electric shaver <NUM> is in the handheld state, the handle induction element <NUM> generates a first induction signal and sends the first induction signal to the control chip <NUM>, in other words, when the handle induction element <NUM> detects that the distance between the electric shaver <NUM> and the operator at the handle induction element <NUM> is almost zero, the control chip <NUM> obtains the first induction signal. It can be understood that, in other embodiments, the distance value, corresponding to the first induction signal, between the electric shaver <NUM> and the operator can also be set according to requirements.

The second induction signal is the signal generated when the electrical signal carried on the head portion induction element <NUM> changes, specifically, the change in the electrical signal mainly refers to the change in the capacitance, since the human body itself carries a certain capacitance, when the human body approaches the head portion induction element <NUM>, the capacitance of the head portion induction element <NUM> increases, and the signal is the second induction signal.

The number of the driven gear <NUM> is multiple, the driving gear <NUM> meshes with the plurality of driven gears <NUM> at the same time, and each driven gear <NUM> has also a unique corresponding transmission shaft assembly <NUM> connected thereto.

Based on the above arrangement, in the embodiment of the present disclosure, if the transmission shaft assembly <NUM> is made of a conductor material, the guide assembly <NUM> may be connected to the control chip <NUM> and the transmission shaft assembly <NUM> at the same time, so that when the cutter head <NUM> is closed relative to the machine body <NUM>, and the transmission shaft assembly <NUM> is cooperated with the cutter head <NUM>, the control chip <NUM> is communicated to the head portion induction element <NUM> through the guide assembly <NUM>, the transmission shaft assembly <NUM> and the inner blade <NUM> in sequence, that is, the second induction signal of the head portion induction element <NUM> is sequentially transmitted along the inner blade <NUM> , the transmission shaft assembly <NUM> and the guide assembly <NUM>, and finally transmitted to the control chip <NUM>. When the cutter head <NUM> is opened relative to the machine body <NUM>, and the transmission shaft assembly <NUM> is separated from the cutter head <NUM>, the transmission shaft assembly <NUM> is disconnected from the cutter head <NUM>, that is, the transmission shaft assembly <NUM> is disconnected from the inner blade <NUM>, so that the transmission shaft assembly <NUM> is indirectly disconnected from the cutter net cover <NUM>, thereby making the control chip <NUM> disconnected from the cutter net cover <NUM>.

Optionally, as shown in <FIG> and <FIG>, as for the guide assembly <NUM>, in the embodiment of the present disclosure, as a first optional embodiment, it may include a first conductive sheet <NUM> and a first conductive wire <NUM>. The first conductive sheet <NUM> is connected to the transmission shaft assembly <NUM>, and two ends of the first conductive wire <NUM> are respectively connected to the control chip <NUM> and the first conductive sheet <NUM>, that is, the control chip <NUM> is communicated to the transmission shaft assembly <NUM> through the first conductive wire <NUM> and the first conductive sheet <NUM> in sequence, when the transmission shaft assembly <NUM> is communicated to the cutter net cover <NUM>, the control chip <NUM> is communicated to the cutter net cover <NUM>.

Optionally, the first conductive sheet <NUM> and the transmission shaft assembly <NUM> are away from one end of the cutter head <NUM>. It can be understood that when the driven gear <NUM> is made of conductive material, the first conductive sheet <NUM> can also be connected to the driven gear, so as to indirectly realize the connection with the transmission shaft assembly <NUM>.

In the above configuration, since the guide assembly <NUM> is disconnected from the cutter head <NUM>, when the cutter head <NUM> is opened relative to the machine body <NUM> and the transmission shaft assembly <NUM> is away from the cutter head <NUM>, so that the guide assembly <NUM> is disconnected from the cutter net cover <NUM>, and the control chip <NUM> is disconnected from the cutter net cover <NUM>, therefore, when the cutter head <NUM> is opened relative to the machine body <NUM>, even if the user touches the cutter net cover <NUM> by mistake, the electric shaver <NUM> will not automatically start up, thereby enhancing the use safety of the electric shaver <NUM>. However, it should be noted that when the cutter head <NUM> is opened relative to the machine body <NUM>, and the user touches by mistake the part of the transmission shaft assembly <NUM> located outside the machine body <NUM> and configured to cooperate with the cutter head <NUM>, the electric shaver <NUM> may still automatically start up.

Therefore, in order to avoid the above-mentioned situation, referring to <FIG>, in the embodiment of the present disclosure, as a second optional embodiment, the guide assembly <NUM> includes a conduction connection assembly <NUM> and a conduction control assembly <NUM>, the conduction connection assembly <NUM> is provided inside the housing <NUM> (that is, inside the machine body <NUM>), and connected to the control chip <NUM>.

When the cutter head <NUM> is opened relative to the machine body <NUM>, the conduction control assembly <NUM> is away from the cutter head <NUM>, so that the control chip <NUM> is disconnected from the head portion induction element <NUM>.

Optionally, the conduction control assembly <NUM> is provided at one end of the working end surface <NUM> of the housing <NUM>, and the conduction connection assembly <NUM> may include a second conductive sheet <NUM> and a second conductive wire <NUM>, and the second conductive sheet <NUM> is connected to one end of the conduction control assembly <NUM> away from the cutter head <NUM>, and the second conductive wire <NUM> is connected to the control chip <NUM> and the second conductive sheet <NUM> at the same time, so that when the conduction control assembly <NUM> is communicated to the head portion induction element <NUM> of the cutter head <NUM>, the control chip <NUM> is communicated to the head portion induction element <NUM> through the second conductive wire <NUM>, the second conductive sheet <NUM> and the conduction control assembly <NUM> in sequence.

When the cutter head <NUM> is opened relative to the machine body <NUM>, the second end <NUM> of the connecting member <NUM> is disconnected from the head portion induction element <NUM>, and at the same time, the control member <NUM> makes the first end <NUM> disconnected from the conduction connection assembly <NUM>, in this way, the control chip <NUM> is disconnected from both the connecting member <NUM> and the head portion induction element <NUM>. In this way, when the cutter head <NUM> is opened relative to the machine body <NUM>, even if the head portion induction element <NUM> or the connecting member <NUM> is touched by mistake, the second induction signal cannot be generated, and the second induction signal cannot be sent to the control chip <NUM>, therefore, there will be no situation that the driving component <NUM> is activated by mistake.

The control connection hole <NUM> has a first opening communicating with the inner cavity of the housing <NUM>, and the cross-sectional area of the blocking component <NUM> is larger than the cross- sectional area of the first opening, therefore, when the connecting component <NUM> has a tendency of moving outward relative to the control connection hole <NUM>, the blocking component <NUM> abuts against the inner wall of the housing <NUM> to prevent the connecting component <NUM> from continuing to move outward, thereby preventing the connecting member <NUM> from moving to the outside of the housing <NUM> as a whole, which leads to a situation that the connecting member <NUM> is separated from the housing <NUM>.

As for the control member <NUM>, in the embodiment of the present disclosure, as an optional embodiment, it may include an elastic component <NUM>. The elastic component <NUM> is connected to the connecting member <NUM>, and the elastic component <NUM> is configured so that the connecting member <NUM> has a tendency of moving away from the conduction connection assembly <NUM>, in this way, when the cutter head <NUM> is closed relative to the machine body <NUM>, the connecting member <NUM> compresses the elastic component <NUM> under the action of the cutter head <NUM>, and the connecting member <NUM> moves in a direction close to the conduction connection assembly <NUM> until the connecting member <NUM> is communicated to the conduction connection assembly <NUM>; and when the cutter head <NUM> is opened relative to the machine body <NUM>, the connecting member <NUM> moves in a direction away from the conduction connection assembly <NUM> under the action of the elastic force of the elastic component <NUM>, so that the connecting member <NUM> is disconnected from the conduction connection assembly <NUM>, thereby making the control chip <NUM> disconnected from the cutter head <NUM>.

The spring is provided in the first hole segment, and one end of the spring away from the limiting step abuts against the hole bottom of the first hole segment, in this way, when the connecting component <NUM> is pressed by the cutter head <NUM>, and moves close to the conduction connection assembly <NUM> provided in the housing <NUM>, the distance between the limiting step and the hole bottom of the first hole segment decreases, so that the elastic component <NUM> is compressed. It can be understood that, in other embodiments, elastic components <NUM> of other structures may also be used, such as elastic rubber block.

In the embodiment of the present disclosure, the first controller <NUM> may be directly communicated to the head portion induction element <NUM> to detect the electrical signal carried on the head portion induction element <NUM>, that is, the capacitance, and when an increase in the capacitance is detected, the driving component <NUM> is controlled to be started, thereby driving the cutter head <NUM> to work; and when the detected capacitance decreases, the driving component <NUM> is controlled to be turned off, so that the cutter head <NUM> stops working, wherein controlling the driving component <NUM> to be started may be controlling the driving component <NUM> to be connected to the electric energy storage module <NUM>, and controlling the driving component <NUM> to be turned off may be controlling the driving component <NUM> to be disconnected from the electric energy storage module <NUM>, that is, by controlling the power on and off of the driving component <NUM>, the starting and stopping of the driving component <NUM> may be controlled.

<FIG> is a schematic view of yet another circuit structure of the electric shaver <NUM> provided by the embodiment of the present disclosure, and the circuit structure shows the control circuit structure of the head portion induction element <NUM>. Referring to <FIG>, as for the control chip <NUM>, in the embodiment of the present disclosure, as another optional embodiment, it may also include a signal generator <NUM>, a conductor member <NUM> and a second controller <NUM> that are connected in sequence. In the above, the conductor member <NUM> is also communicated to the head portion induction element <NUM>, and the second controller <NUM> is also connected to the driving component <NUM>. Optionally, the second controller <NUM> may be an integrated circuit chip, which has signal processing capability; and the second controller <NUM> may also be a general-purpose processor, for example, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a discrete gate or a transistor logic device, or a discrete hardware assembly, in addition, a general-purpose processor may also be a microprocessor or any other conventional processor.

In an embodiment of the present disclosure, the signal generator <NUM> is configured to generate an initial alternating-current signal and transmit the initial alternating-current signal to the conductor member <NUM>. The second controller <NUM> is configured to collect the target alternating-current signal output by the conductor member <NUM> after the initial alternating-current signal is transmitted to the conductor member <NUM>, and determine whether the electrical signal carried on the cutter net cover <NUM> changes according to induction result generated by the target alternating-current signal, thereby controlling the driving component <NUM> to start and stop. When the driving component <NUM> is started, the driving component <NUM> drives the cutter head <NUM> to work; and when the driving component <NUM> is turned off, the cutter head <NUM> stops working accordingly. In the above, controlling the driving component <NUM> to be started may be controlling the driving component <NUM> to be connected to the electric power storage module <NUM>, and controlling the driving component <NUM> to be turned off may be controlling the driving component <NUM> to be disconnected from the electric power storage module <NUM>, that is, by controlling the power on and off of the driving component <NUM>, the starting and stopping of the driving component <NUM> may be controlled.

Furthermore, the working principle of the control chip <NUM> shown in <FIG> is that when the human body is far away from the cutter net cover <NUM> (that is, the head portion induction element <NUM>), the intensity of target alternating-current signal output by the conductor member <NUM> is equivalent to the intensity of the initial alternating-current signal; and when the human body is close to the cutter net cover <NUM>, the human body carries a certain capacitance, which may have a bypass effect on the initial alternating-current signal transmitted on the conductor member <NUM>, so that the conductor member <NUM> outputs the target alternating-current signal that is weaker than the initial alternating-current signal, the second controller <NUM> can generate an induction result according to the intensity of the target alternating-current signal, so as to determine whether the electrical signal carried on the cutter net cover <NUM> changes, thereby controlling the driving component <NUM> to start and stop. When the driving component <NUM> is started, the driving component <NUM> drives the cutter head <NUM> to work; and when the driving component <NUM> is turned off, the cutter head <NUM> stops working accordingly.

Specifically, the process that the second controller <NUM> generates the induction result according to the intensity of the target alternating-current signal to determine whether the electrical signal carried on the cutter net cover <NUM> changes may be that when the intensity of the target alternating-current signal is less than a preset intensity threshold, it indicates that the electrical signal carried on the cutter net cover <NUM> increases, then the first induction result of controlling the driving component <NUM> to be started is generated; and when the intensity of the target alternating-current signal is greater than or equal to the preset intensity threshold, it indicates that the electrical signal carried on the cutter net cover <NUM> has not changed or decreased, then the second induction result representing that the electrical signal carried on the cutter net cover <NUM> has not changed or decreased is generated, the second induction result controls the driving component <NUM> to be turned off, and makes the cutter head <NUM> stop working.

To sum up, the electric shaver <NUM> provided by the embodiments of the present disclosure includes a machine body <NUM> and a cutter head <NUM>.

The control chip <NUM> is configured to control the driving component <NUM> to start and stop when detecting that the electrical signal carried on the cutter net cover <NUM> changes. When the driving component <NUM> is started, the driving component <NUM> drives the cutter head <NUM> to work; and when the driving component <NUM> is turned off, the cutter head <NUM> stops working.

In this way, when the human body is close to or away from the cutter net cover <NUM>, since the human body itself carries a certain capacitance, the electrical signal detected by the control chip <NUM> will be changed, and according to the change, the driving component <NUM> is controlled to be started to drive the cutter head <NUM> to work, or the driving component <NUM> is controlled to be turned off, so that the cutter head <NUM> stops working. For example, when the human body is close to the cutter net cover <NUM>, the capacitance detected by the control chip <NUM> increases, and the driving component <NUM> is controlled to be started to drive the cutter head <NUM> to work; and when the human body is away from the cutter net cover <NUM>, the capacitance detected by the control chip <NUM> decreases, and the driving component <NUM> is controlled to be turned off, so that the cutter head <NUM> stops working, thereby achieving the purpose of the present disclosure that when the user brings the cutter net cover <NUM> of the electric shaver <NUM> close to the target area, the electric shaver <NUM> may be automatically activated, and when the user moves the cutter net cover <NUM> of the electric shaver <NUM> away from the target area, the electric shaver <NUM> may be automatically turned off, which greatly enhances the convenience of using the electric shaver <NUM>.
