Description

Technical Field

[0001] This invention relates to the field of personal care products technology, and in particular to a shaving device. Background Technology

[0002] In daily personal care, people often need to shave off unwanted hair, such as head hair, arm hair, leg hair, and nose hair. Therefore, various shaving devices have emerged, such as hair clippers for trimming head hair, shaving clippers for trimming arm and leg hair, and nose hair trimmers. Traditional shaving devices mostly use push-button switches, which protrude from the casing. This protruding switch not only increases the difficulty and cost of waterproofing the device but also affects its aesthetics. Summary of the Invention

[0003] The present invention provides a shaving device to solve the technical problem that the button switch on the outer shell of the traditional shaving device not only increases the difficulty and cost of waterproofing the device, but also affects the aesthetics of the device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This invention provides a shaving device, comprising:

[0006] The fuselage assembly includes a main body and a drive structure disposed within the main body;

[0007] A cutting head assembly includes a housing and a blade structure disposed within the housing;

[0008] The drive structure is connected to the blade structure and can drive the blade structure to rotate, so as to cut the hair that enters the housing; a drive switch is provided between the housing and the main body, and the housing can rotate circumferentially relative to the main body to switch between an open position and a closed position; there are multiple open positions and multiple closed positions, and the open positions and closed positions are arranged alternately circumferentially; in the open position, the drive switch is connected to the control circuit to trigger the drive structure to drive the blade structure to rotate; in the closed position, the drive switch is disconnected from the control circuit.

[0009] In one embodiment, the drive switch includes a push-button spring and an electronic switch. The push-button spring has a fixed end and a pressing end. The fixed end is disposed in one of the main body and the outer shell. The outer shell and the main body are rotatable relative to each other so that the pressing end can overcome the elastic resistance of the push-button spring to contact the electronic switch, thereby enabling the electronic switch to connect the control circuit. The pressing end can also be disengaged from the electronic switch.

[0010] In one embodiment, the outer casing has a plurality of first protrusions arranged circumferentially at intervals on the side facing the main body, and the pressing end has a second protrusion; when the outer casing rotates relative to the main body, the first protrusions can press the second protrusions toward the side of the electronic switch and cause the pressing end to press the electronic switch; after rotating to a certain position, the second protrusions can also be positioned between two adjacent first protrusions, so that the pressing end disengages from the electronic switch and completes a button press action.

[0011] In one embodiment, the two sides of the first protrusion that move circumferentially are curved surfaces or inclined surfaces; the two sides of the second protrusion that move circumferentially are curved surfaces or inclined surfaces.

[0012] In one embodiment, in the closed position, the second protrusion contacts and abuts against two adjacent first protrusions on opposite sides along the circumferential direction.

[0013] In one embodiment, the pressing spring arm is further provided with a limiting groove. When one of the first protrusions presses the second protrusion into contact with the electronic switch, the other different first protrusion engages in the limiting groove to maintain the current open position. The first protrusion located in the limiting groove can also disengage along the groove wall.

[0014] In one embodiment, the outer casing and the body are selectively rotatable relative to each other in a clockwise and counterclockwise direction for a full revolution.

[0015] In one embodiment, the main body includes a body, a mechanism, and a cover, the cover closing the mechanism inside the body, and the drive structure being installed on the mechanism; the outer shell is axially limited to the cover, and the outer shell and the cover are circumferentially rotatable relative to each other, and the drive switch is disposed between the outer shell and the cover.

[0016] In one embodiment, one of the outer shell and the cover is provided with a first hook, and the other is provided with a second hook. The first hook and the second hook engage to limit the outer shell and the cover in the axial direction and to allow them to rotate in the circumferential direction.

[0017] In one embodiment, the outer casing includes a blade housing and a screw cap. The blade structure is disposed on the blade housing, and the side wall of the blade housing is provided with a protruding drive block. The screw cap is axially limited to the cover and can rotate relative to the cover circumferentially. The side wall of the screw cap is provided with a plurality of circumferentially spaced toothed grooves. The blade housing can drive the drive block to selectively engage with different toothed grooves along the axial direction, thereby enabling the blade housing to drive the screw cap to rotate synchronously.

[0018] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0019] The shaving device of this invention has a housing that can rotate circumferentially relative to the main body, and can switch between multiple open and closed positions circumferentially during this rotation. In the open position, a drive switch connects to the control circuit, triggering the drive structure to rotate the blade structure; in the closed position, the drive switch disconnects from the control circuit, thereby stopping the rotation of the blade structure by the drive structure. Therefore, the shaving device provided by this invention facilitates user operation by opening and closing the device, especially in situations requiring multiple on / off cycles, as continuous rotation in one direction allows for alternating switching between open and closed states while maintaining overall aesthetic integrity.

[0030] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] refer to Figure 1 This invention provides a shaving device 10, which includes a body assembly 100 and a blade assembly 200. The blade assembly 200 is connected to the body assembly 100 and is used by a user to remove hair, such as beard, head hair, hand hair, leg hair, and nose hair. The blade assembly 200 is detachably connected to the body assembly 100, allowing the user to easily replace different types of blades on the body assembly 100 to remove beard, head hair, hand hair, leg hair, and nose hair. It is understood that in other embodiments, the blade assembly 200 may be non-detachable depending on actual usage needs.

[0034] refer to Figure 2 and Figure 3The body assembly 100 includes a main body 110 and a drive structure 120 disposed within the main body 110. In this embodiment, the main body 110 is provided with a mounting cavity 101, and the drive structure 120 is located within the mounting cavity 101. It should be explained that the drive structure 120 includes a motor and a power supply. The output end of the motor is connected to the blade assembly of the cutter head assembly 200, and the power supply provides electrical energy to the motor, thereby enabling the motor to drive the blade assembly of the cutter head assembly 200 to rotate, thus allowing the rotating blades to cut hair. The power supply can be built into the mounting cavity 101 to provide electrical energy, or an external portable power source can be used.

[0035] The main body 110 includes a body 111, a mechanism 112, and a cover 113. A mounting cavity 101 is formed within the body 111, and the cover 113 closes the mechanism 112 within the body 111. The drive structure 120 is mounted on the mechanism 112. It should be noted that the mechanism 112, used as a support, not only mounts the drive structure 120, but also houses a motherboard and a charging interface. The motherboard integrates control circuitry and is connected to the drive structure 120. The charging interface is connected to the motherboard and can be exposed from the body 111 through the mounting cavity 101, allowing users to charge the power supply mounted on the mechanism 112 via the exposed charging interface.

[0036] The blade assembly 200 includes a housing 210 and a blade structure 220 disposed within the housing 210. The blade structure 220 can be understood as the blade assembly mentioned above. The blade structure 220 is connected to the drive structure 120. Specifically, the motor in the drive structure 120 is connected to the blade structure 220, and the motor can drive the blade structure 220 to rotate, thereby cutting the hair that enters the housing 210 through the rotation of the blade structure 220.

[0037] A drive switch 300 is provided between the outer casing 210 and the main body 110. The drive switch 300 can close the control circuit where the blade structure 220 is located, thereby triggering the drive structure 120 to drive the blade structure 220 to rotate. The drive switch 300 can also be opened to be in a state of being disconnected from the control circuit. At this time, the drive structure 120 cannot drive the blade structure 220 to rotate, and the operation of the shaving device 10 stops.

[0038] The outer casing 210 is circumferentially rotatable relative to the main body 110 to switch between an open position and a closed position. Specifically, the outer casing 210 is axially limited to the cover 113, and the outer casing 210 is also circumferentially rotatable relative to the cover 113, at which time the drive switch 300 is disposed between the outer casing 210 and the cover 113. Further, refer to... Figure 4One of the outer shell 210 and the cover 113 is provided with a first hook 410 and the other is provided with a second hook 420. The first hook 410 and the second hook 420 are engaged and cooperated, that is, the two hook each other to complete the limiting, so as to realize the limiting of the outer shell 210 and the cover 113 along the axial direction and the rotation along the circumferential direction.

[0039] The aforementioned open and closed positions are both multiple, and the open and closed positions are arranged alternately along the circumference. In the open position, the drive switch 300 connects the control circuit to trigger the drive structure 120 to drive the blade structure 220 to rotate. In the closed position, the drive switch 300 disconnects from the control circuit.

[0040] For a more detailed explanation, please refer to [link / reference]. Figure 2 and Figure 4 The drive switch 300 includes a press spring arm 310 and an electronic switch 320. The press spring arm 310 has a fixed end 311 and a pressing end 312. The fixed end 311 is disposed in one of the cover 113 and the housing 210. Figure 4 The diagram illustrates that the fixed end 311 is mounted on the cover 113, and the outer casing 210 and the cover 113 can rotate relative to each other. This allows the pressing end 312 to overcome the elastic resistance of the pressing spring arm 310 and press the electronic switch 320, thereby activating the electronic switch 320 and connecting the control circuit. When the electronic switch 320 is activated in the control circuit, the blade structure 220 can cut the hair under the drive of the drive structure 120. When the outer casing 210 and the cover 113 rotate to the circumferentially closed position, the pressing end 312 can disengage from the electronic switch 320 under the elastic force of the pressing spring arm 310. This can be understood as follows: when rotating to the next gear position, the pressing spring arm 310 repeats the pressing and releasing action on the electronic switch 320, thus disconnecting the control circuit.

[0041] The outer casing 210 has a plurality of first protrusions 510 arranged circumferentially on the side facing the cover 113, and a second protrusion 520 is provided on the side of the pressing end 312 facing away from the electronic switch 320. When the outer casing 210 rotates relative to the cover 113, the first protrusions 510 can press the second protrusions 520 toward the electronic switch 320, causing the pressing end 312 to press the electronic switch 320. At this time, the relative position of the outer casing 210 and the cover 113 can be understood as the open position. After rotating to one position, the second protrusion 520 can remain between two adjacent first protrusions 510, so that the pressing end 312 can disengage from the electronic switch 320 under the elastic restoring force of the pressing spring arm 310 to complete a button action. At this time, the relative position of the outer casing 210 and the cover 113 can be understood as the closed position. When the outer casing 210 rotates relative to the cover 113, in order to switch between the open and closed positions, the two sides of the first protrusion 510 that move circumferentially can be set as curved surfaces or inclined surfaces. Similarly, the two sides of the second protrusion 520 that move circumferentially can also be set as curved surfaces or inclined surfaces. In this way, the outer casing 210 and the cover 113 can rotate not only clockwise but also counterclockwise. If only unidirectional rotation of the outer casing 210 relative to the cover 113 is desired, it is only necessary to set curved surfaces or inclined surfaces on the same side of the first protrusion 510 and the second protrusion 520 that move circumferentially.

[0042] It should be noted that in the closed position, the second protrusion 520 contacts and abuts against the two adjacent first protrusions 510 on opposite sides along the circumferential direction. Thus, unless the force driving the housing 210 and the cover 113 to rotate relative to each other is sufficiently large, the relative positions of the housing 210 and the cover 113 will not easily shift, ensuring the stability of the device in the closed position. Similarly, to ensure the stability of the device in the open position, the shaving device 10 provided by this invention can also be provided with a limiting groove 313 on the pressing spring arm 310. Figure 4 The diagram illustrates that the limiting groove 313 is located between the fixed end 311 and the pressing end 312. However, the specific location of the limiting groove 313 is not limited to the aforementioned location and can be set at any other location. When one of the first protrusions 510 presses the second protrusion 520 against the pressing electronic switch 320, the other, different first protrusion 510 engages within the limiting groove 313 to maintain the current open position. The first protrusion 510 located within the limiting groove 313 can also disengage from the limiting groove 313 along its wall. The force driving the relative rotation of the housing 210 and the cover 113 can cause the first protrusion 510 to move along the wall of the limiting groove 313. This can be achieved by designing the circumferential sidewall of the limiting groove 313 as an inclined surface or a curved surface.

[0043] refer to Figure 5In the shaving device 10 of this embodiment, the outer shell 210 is circumferentially rotatable relative to the main body 110, and the outer shell 210 can switch between multiple open and closed positions in the circumferential direction during rotation relative to the main body 110. In the open position, the drive switch 300 is connected and energized to the control circuit, triggering the drive structure 120 to rotate the blade structure 220. In the closed position, the drive switch 300 is disconnected from the control circuit, thereby stopping the rotation of the blade structure 220 by the drive structure 120. Therefore, the shaving device 10 provided by this invention facilitates the user's operation of opening and closing the device, especially for situations requiring multiple on / off cycles, as continuous rotation in one direction allows for alternating switching between open and closed states while maintaining overall aesthetic integrity.

[0044] When the movement 112 is closed onto the body 111, the cover 113 has a sealing ring 114 on its side. Figure 5 The schematic sealing ring 114 is located between the body 113 and the cover 113, thereby ensuring that external moisture can enter the body 113 and thus ensuring the safe use of the components on the movement 112.

[0045] In one embodiment, reference Figure 3 and Figure 6 The outer casing 210 includes a blade housing 211 and a screw cap 212. The blade structure 220 is disposed on the blade housing 211, and a protruding drive block 213 is provided on the side wall of the blade housing 211. Figure 6 The diagram illustrates that the drive block 213 is disposed on the inner side wall of the blade housing 211 to enhance the overall appearance of the blade housing 211. It is understood that the drive block 213 can also be disposed on the outer side wall of the blade housing 211. The cap 212 is axially limited to the cover 113 and can rotate circumferentially relative to the cover 113. The side wall of the cap 212 is provided with multiple circumferentially spaced toothed grooves 214. The blade housing 211 can selectively engage the drive block 213 with different toothed grooves 214 along the axial direction, thereby enabling the cap 212 to rotate synchronously. Based on this structure, when the user needs to use different shaver heads, or when the shaver head needs to be replaced due to its lifespan, the blade housing 211 can be detached from the cap 212, making operation very convenient. It should also be noted that because there are multiple toothed grooves 214, the blade housing 211, which has the blade structure 220 installed, can engage with the cap 212 at multiple different circumferential angles along the direction of the toothed grooves 214.

[0046] To improve the speed and convenience of aligning and installing the blade housing 211 and the screw cap 212, and to enhance the stability of their fit, a magnetic assembly can be provided between the blade housing 211 and the screw cap 212. This magnetic assembly includes a first magnetic element and a second magnetic element, which are respectively disposed on the blade housing 211 and the screw cap 212. The first and second magnetic elements are magnetically attracted to each other, allowing the blade housing 211 and the screw cap 212 to align and come closer together under the influence of magnetic force to complete the fit. It should be noted that at least one of the first and second magnetic elements is a magnet, while the other can be a magnetically attracted metal or a magnet.

[0047] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
