The electrical conductor 140 penetrates through the electrical conductive hole 1101, and based on the structural design, the cutting structure 120 serves as a first end of a first electrical conductive path, and the first electrical conductive path is used for receiving a first inductive capacitance between the cutting structure 120 and the ground when the cutting structure 120 approaches or contacts the skin of the human body, and is transmitted to the circuit board assembly through the electrical conductive floating member 130 and the electrical conductor 140 in sequence; the circuit board assembly is used for starting the motor when receiving the first induction capacitor.
In one embodiment, the tool holder 121 serves as a first end of a first conductive path for receiving a first inductive capacitance between the tool holder 121 and ground when the tool holder 121 approaches or contacts the skin of a human body, and transferring the first inductive capacitance to the circuit board assembly through the conductive floating member 130 and the conductive body 140 in sequence.
In another embodiment, the knife net 1221 serves as a first end of a first conductive path, and the first conductive path is configured to receive a first inductive capacitance between the knife net 1221 and the ground when the knife net 1221 approaches or contacts the skin of the human body, and to transmit the first inductive capacitance to the circuit board assembly through the conductive floating member 130 and the conductive body 140 in sequence.
Specifically, the conductive body 140 may further include a first conductor 141 and a second conductor 142, wherein the first conductor 141 is slidably connected to the conductive hole 1101, the second conductor 142 is an elastic member, the second conductor 142 is located in the conductive hole 1101 and elastically abuts against the connection portion 131, and a side of the second conductor 142 away from the connection portion 131 elastically abuts against the first conductor 141.
Based on the structural design, the knife rest 121 or the knife net 1221 serves as a first end of a first conductive path, the first conductive path is used for receiving a first induction capacitance between the knife rest 121 (or the knife net 1221) and the ground when the knife rest 121 (or the knife net 1221) approaches or contacts the skin of a human body, and is transmitted to the circuit board assembly through the conductive floating member 130, the second conductor 142 and the first conductor 141 in sequence, and the circuit board assembly is electrically connected to a second end of the first conductive path and is used for starting a motor when receiving the first induction capacitance.
In comparison with the prior art, referring to fig. 1, the floating shaver according to the present invention includes a cutter head assembly 100 and a body assembly 200. The floating shaver is provided with a first conductive path, the first end of which is the cartridge 121 or the foil 1221 in the cartridge assembly 100. The second end is connected to a circuit board assembly in the handle assembly 220. When shaving, the knife rest 121 or the knife net 1221 is pressed close to the skin of the human body such as the lower jaw, the cheek and the like; because the human skin has a certain charge, when the human skin directly contacts or is close to the knife rest 121 or the knife net 1221, the knife rest 121 or the knife net 1221 absorbs the human skin capacitance formed between the human skin and the ground from the close position, that is, the first inductive capacitance. When the circuit board assembly receives the first sensing capacitor, the motor is started to drive the rotating cutter head 1222 in the cutting unit 112 to rotate through the gear bin 210, so as to shave, thereby avoiding the problem that the shaver cannot normally work due to the damage or failure of a mechanical switch button, and ensuring that the shaving device can be reliably used for a long time.
In the embodiment of the present invention, the conductive floating member 130, in combination with the first and second conductors 141 and 142 electrically connected to the respective tool holders 121, transfers the first sensing capacitance to the circuit board assembly to perform a conductive function, and also functions to enable the respective cutting structures 120 to float with respect to the head cover 110.
It should be noted that, in order to realize the electrical connection between the connection portion 131 and the circuit board assembly, referring to fig. 4 and 5, the first conductor 141 can be electrically connected by a conductive structural member (i.e., the third conductor 212) abutting against the conductive hole 1101.
It should be noted that, if the first conductor 141 is mounted on the head cover 110, in order to ensure that the first conductor 141 is electrically connected with the conductive structural member, the first conductor 141 and the conductive structural member need to be in close contact, and the conductive structural member needs to abut against the first conductor 141. Based on the structural design, when the conductive structural member (i.e. the third conductor 212 in the figure) abuts against the first conductor 141, the first conductor 141 moves towards the direction of the connecting portion 131, and since the second conductor 142 is an elastic member, the second conductor 142 deforms in the floating direction, i.e. the size in the floating direction is reduced, so that the first conductor 141 can be prevented from displacing, and after the conductive floating member 130 cancels the abutting, the second conductor 142 can be reset because the second conductor 142 is an elastic member, thereby preventing the first conductor 141 from being displaced, so that the position of the first conductor 141 is always ensured not to be displaced, and the first conductor can always be tightly abutted against the conductive structural member (the third conductor 212).
In a specific embodiment, the first conductor 141 is preferably a floating pin, such that when the first conductor 141 is itself pressed by the conductive structure, it is displaced in the floating direction and is reset when the pressing of the conductive structure is removed; the second conductor 142 is preferably a coil spring, which is commercially available in standard parts with various dimensions and properties, so that it can be manufactured without special production, which is beneficial to reduce the production and manufacturing cost.
In one embodiment, referring to fig. 3 and 6, the other end of the elastic arm 132 away from the connecting portion 131 is provided with an abutting portion 133, and the abutting portion 133 is disposed in an arc shape, and the salient point thereof abuts against the tool holder 121. In the floating process of the cutting structure 120, the other end of the elastic arm 132 away from the connecting portion 131 and the tool holder 121 can generate relative displacement, if the other end of the elastic arm 132 away from the connecting portion 131 is abutted against the tool holder 121 through the convex tip structure, in the process, the tool holder 121 can be worn, and based on the structure, the conductive floating piece 130 is abutted against the tool holder 121 through the abutting portion 133, the abutting portion 133 is in an arc shape, the salient point of the conductive floating piece is abutted against the tool holder 121, so that the conductive floating piece 130 is abutted against the tool holder 121 through the smooth structure, and the abrasion of the floating piece to the tool holder 121 can be effectively reduced.
In one embodiment, referring to fig. 1, a limiting protrusion 112 protrudes from a wall of the conductive hole 1101, and the limiting protrusion 112 prevents the first conductor 141 from being detached from the conductive hole 1101. Therefore, in the assembly process, after the first conductor 141 is placed in the conductive hole 1101, the connecting part 131 is fixed to the head cover 110, and the assembly of the first conductor 141 is completed, and other structures are not required to be fastened, which is beneficial to improving the assembly efficiency.
In this embodiment, the limiting protrusion 112 is annularly disposed along the hole wall circumference of the conductive hole 1101.
In one embodiment, the connecting portion 131 is provided with at least one fixing hole 1311 disposed therethrough; skull 110 is equipped with at least one mounting, and each mounting wears to locate a fixed orifices 1311 respectively, and specifically each mounting still can be including connecting in skull 110 and along the fixed column that the direction of floating extended the setting and connect in the riveting head of the fixed column one end of keeping away from skull 110, and a fixed orifices 1311 is worn to locate respectively for each fixed column, and each riveting head all butts connecting portion 131 and deviates from the side of skull 110. Before the connection portion 131 is assembled to the head cover 110, a fixing member is not formed, and preferably, at least one fixing blank column 111 is provided at the head cover 110, and riveting is performed through a free end of each fixing blank column 111, wherein a part deformed by riveting forms a riveting head, and a part not riveted is a fixing column.
Specifically, the cross-sectional shape of each fixing column is matched with the hole shape of the corresponding fixing hole 1311, and after each fixing column passes through the corresponding positioning hole, the connecting portion 131 can be limited to move in the direction perpendicular to the central axis of the fixing column.
In other embodiments, the connection between connection portion 131 and head cover 110 is a detachable connection, and the detachable connection may be implemented by using screws.
In one embodiment, the tool holder 121 includes a tool holder body and an abutment projection attached to the peripheral side of the tool holder body, the abutment projection being in abutment with the corresponding resilient arm 132. Based on the structural arrangement, the structural design of the tool holder 121 body can be the structural design of the existing tool holder 121, that is, the tool holder 121 of the present invention can be realized by adding the abutting protrusion on the peripheral side of the existing tool holder 121 on the basis of the structure of the existing tool holder 121, which is beneficial to reducing the structural improvement of the tool holder 121. Specifically, in the embodiment of the present invention, the abutting projection is in a plate structure.
In one embodiment, the blade holder 121 is a body of electrically conductive material when the blade holder 121 or the blade mesh 1221 is used as the first end of the first electrically conductive path. The tool holder 121 is directly made of a conductive material, and thus, the processing is easy. Alternatively, the outer surface of the tool holder 121 is provided with a conductive layer. By providing the blade holder 121 with a conductive layer on the outer surface of the plastic part, the weight is reduced. Similarly, when the grid 1221 serves as a first end of a first conductive path, the grid 1221 is a conductor; alternatively, the outer surface of the foil 1221 is provided with a conductive layer. In both ways, the blade holder 121 (or the blade net 1221) can absorb the capacitance of the human skin formed between the human skin and the ground from the position close to the human skin as the first end of the first conductive path.
In one embodiment, the gear cartridge 210 is used for connection with the body assembly 200 and also for connection with the aforementioned cutter head assembly 100, the gear cartridge 210 comprises a gear cartridge body 211 and a third conductor 212 mounted to the gear cartridge body 211, the third conductor 212 is capable of abutting the conductive hole 1101 from an aperture of the conductive hole 1101 away from the connecting portion 131, the third conductor 212 is electrically connected with the conductive body 140; based on the structural design, the first sensing capacitor is sequentially transmitted to the circuit board assembly through the conductive floating member 130, the conductive body 140 and the third conductor 212, and in addition, because the conductive body 140 further comprises the second conductor 142 and the first conductor 141, based on the structural design, the first sensing capacitor is sequentially transmitted to the circuit board assembly through the conductive floating member 130, the conductive body 140 and the third conductor 212.

When the human skin is in direct contact with or close to the gear carrier cover plate 2112 during shaving, the gear carrier cover plate 2112 absorbs the human skin capacitance formed between the human skin and the ground from the close position, namely, the second induced capacitance. When the circuit board assembly receives the second sensing capacitor, the motor is started to drive the rotary cutter head 1222 in the cutting unit 112 to rotate through the gear bin 210, so that the motor can be started without forming the first sensing capacitor by the cutter holder 121 or the cutter net 1221 and the ground. In particular, when the first inductive capacitance cannot be formed between the tool post 121 or the tool net 1221 and the ground due to a failure or the like, the motor can be started by using the second inductive capacitance formed between the carrier cover plate 2112 and the ground.
In one embodiment, the carrier cover plate 2112 is a conductor, and the carrier cover plate 2112 is made of a conductive material directly and is easy to machine. Alternatively, the outer surface of the carrier cover plate 2112 is provided with a conductive layer.
