Description

Technical Field

[0001] This utility model relates to the field of hairdressing equipment technology, and in particular to a razor. Background Technology

[0002] As a commonly used electric hair-cutting tool for men, razors have a large user base and a broad market prospect. Currently, razors are generally turned on or off by manually pressing a power button. In actual use, it is easy to accidentally press and touch the power button, causing the razor to turn on unexpectedly, resulting in unnecessary power waste and affecting normal use. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a razor that solves the problem that existing razors are easily accidentally turned on.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a shaver, including a magnet, a power switch, a magnetic induction switch, and a shaver head output unit controlled by the magnetic induction switch. The magnet is located on one side of the power switch, and the power switch is magnetically attracted to the housing by the magnet, so that the power switch can be flipped to bring the magnet closer to or away from the magnetic induction range of the magnetic induction switch. When it is close, the magnetic induction switch is triggered to start the shaver head output unit, and when it is away, the magnet is removed from the magnetic induction range of the magnetic induction switch to turn off the shaver head output unit.

[0005] Furthermore, a mounting groove is provided on one side of the switch, and the magnet is embedded in the mounting groove accordingly.

[0006] By adopting the above technical solution, the magnet is placed in the mounting groove, which makes it easier to keep the side of the switch flat and improves the integration of the two after assembly.

[0007] Furthermore, a metal part is provided on the housing, and the magnet is magnetically attracted to the metal part so that the switch is magnetically connected to the housing.

[0008] By adopting the above technical solution, the metal component setting allows the switch to be magnetically attracted to the housing by a magnet, increasing the magnetic attraction stability between the switch and the housing.

[0009] Furthermore, the metal component includes a metal block disposed within the housing, with a groove on the inner wall of the housing for accommodating the metal block; or the metal component includes a metal plate formed on the surface of the housing.

[0010] By adopting the above technical solution, the metal block is placed in the groove inside the housing, which makes it easy to hide the metal block. Of course, the metal block can also be omitted. The metal part can be a metal plate placed in the housing corresponding to the position of the switch, which can also play a magnetic attraction role.

[0011] Furthermore, the switch is magnetically attached to the housing so that when the magnet approaches the magnetic switch, the switch can be slid to allow the magnet to enter or leave the magnetic field of the switch.

[0012] By adopting the above technical solution, the power switch is slidably mounted on the housing. To turn on the shaver, the magnet on the power switch approaches the magnetic switch, and the sliding of the power switch allows it to enter or leave the magnetic field of the switch, thus enabling the shaver to be turned on. When the magnet moves away from the magnetic switch as the power switch rotates, sliding the power switch will not trigger the magnetic switch, thus entering a safe mode. In this mode, users can freely manipulate the power switch to enhance the shaver's usability. Simultaneously, this mode also prevents accidental activation of the shaver, making it safer to carry and use.

[0013] Furthermore, a groove is provided on the housing, and the switch is correspondingly slidably disposed in the groove.

[0014] By adopting the above technical solution, the slide groove is designed to facilitate the concealment of the switch, and at the same time, the sliding stroke of the switch is specifically limited within the slide groove.

[0015] Furthermore, the slide groove is equipped with a slide rail, and the side of the switch is equipped with a slide path that cooperates with the slide rail.

[0016] By adopting the above technical solution, the design of the slide rail and slide path facilitates the sliding of the switch.

[0017] Furthermore, auxiliary magnets are provided at both ends of the corresponding slide groove inside the housing, and the auxiliary magnets are attracted to the main magnets by magnetism.

[0018] By adopting the above technical solution, the design of the auxiliary magnet can improve the magnetic attraction between the switch and the housing. At the same time, by setting auxiliary magnets at both ends of the slide, the magnetic attraction between the auxiliary magnets causes the switch to strike the slide when it slides into place, thus producing a "click" sound, which improves the feel of the shaver switch.

[0019] Furthermore, when the switch is slid to its extreme position, the center line of the magnet and the center line of the auxiliary magnet do not coincide.

[0020] By adopting the above technical solution, the non-coincident center line has the following effects: the magnet is always subjected to a force in the direction of alignment with the center line of the auxiliary magnet, so the switch is always pressed against the end face of the housing. First, it ensures that the switch will not easily move in the opposite direction; second, there will be a crisp knocking sound after sliding; third, the switch and the end face of the housing are always pressed tightly without gaps; fourth, there is magnetic assistance during sliding, and with just a little force, the switch will be automatically attracted into place by the magnetic force and can turn the device on and off, making it more effortless for the user. The above four points effectively improve the user experience, product aesthetics and stability.

[0021] Furthermore, magnetic switches include any one of reed switches, Hall elements, and magnetic sensors.

[0022] By adopting the above technical solutions, reed switches, Hall elements, and magnetic sensors have a wide range of applications and high reliability.

[0023] Furthermore, the cutter head output unit includes a moving cutter head, a drive mechanism, and a circuit board. The magnetic switch and the drive mechanism are both electrically connected to the circuit board, and the drive mechanism is used to drive the moving cutter head to reciprocate.

[0024] Compared with the prior art, the advantages of this utility model are:

[0025] In this invention, a magnet and a magnetic switch are magnetically inductively connected, thereby controlling the shaver's start and stop. The magnet is located on one side of the switch, allowing the switch to be magnetically and detachably mounted on the housing. When the switch is flipped to the other side and magnetically connected to the housing, the magnet moves away from the magnetic switch, thus removing it from the switch's magnetic field and turning the shaver off. In this way, by flipping the switch to move the magnet away from or near the magnetic switch, the shaver can be turned on or off. This unique starting method also prevents accidental activation of the shaver when the switch is flipped to a position where the magnet is away from the magnetic switch, further reducing the probability of accidental activation during carrying or storage and effectively improving product safety.

[0034] 500 magnetic induction switch. Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] Reference Figure 1 A shaver includes a magnet 220, a power switch 200, a magnetic switch 500, and a shaver head output unit controlled by the magnetic switch 500. The magnet 220 is located on one side of the power switch 200 (for ease of description, this side of the power switch 200 is referred to as the back side, and the opposite side is referred to as the front side). The power switch 200 is magnetically attracted to the housing 100 by the magnet 220 on the back side. This allows the power switch 200 to be magnetically attracted to the housing 100 from either the front or the back side. When the back side is magnetically attracted to the housing 100, that is, when the magnet 220 is positioned close to the magnetic switch 500, the magnet 220 enters the sensing range of the magnetic switch 500, thereby triggering the magnetic switch 500. The magnetic switch 500 detects the magnetic field and sends an electrical signal to the shaver head output unit, thereby turning on the shaver. When the switch 200 is flipped so that its front side is magnetically connected to the housing 100, the magnet 220 moves away from the magnetic switch 500 and is out of the sensing range of the magnetic switch 500. The magnetic switch 500 will not be triggered, thus turning off the shaver. In this way, when the front side of the switch 200 is connected to the housing 100, it can effectively prevent the shaver from being accidentally triggered when carried or used. Compared with the traditional button switch method, this embodiment can effectively prevent the shaver from being accidentally turned on, thereby improving the safety of carrying or placing the shaver.

[0037] Referring to 1, in order to hide and store the magnet 220 and optimize the volume of the combination of the switch 200 and the magnet 220, a mounting groove 210 is provided on the back of the switch 200, and the corresponding magnet 220 is assembled in the mounting groove 210 to be combined with the switch 200.

[0038] In this embodiment, the housing 100 is provided with a metal part corresponding to the magnet 220, so that the switch can be magnetically attracted to the housing 100 by the magnet 220. As one embodiment of the metal part, the metal part can be a separate metal block, and a groove 120 can be provided inside the housing 100 (see reference). Figure 4Then, the metal block is placed in the groove 120 to limit and hide the metal block.

[0039] As another embodiment of the metal part, the metal part can also be the housing 100 itself or a metal plate provided on its surface, as long as it can form a magnetic adsorption with the magnet 220 so that the switch 200 can be magnetically and detachably installed on the housing 100. The metal part can also be other components or structures. For example, the metal part can also be other metal parts inside the shaver. Common metal parts inside the shaver include motor housing, spring, metal screw and electrode plate, etc., which will not be described in detail here.

[0040] Reference Figure 2 and 3 , ( Figure 2 The image shown is the front of the power switch 200. Figure 3 (The back of the switch 200 is shown) The above-mentioned start and stop of the shaver relies on disassembling and flipping the switch 200, and whether the magnet 220 on the side of the switch 200 triggers the magnetic switch 500, thereby turning the shaver on or off. In order to further improve the convenience, practicality and playability of turning the shaver on or off, in this embodiment, a groove 110 is provided on the housing 100, and the switch 200 is correspondingly slidably disposed in the groove 110. The sliding direction of the groove 110 is along the length direction of the housing 100. In this way, when the switch 200 contacts the housing 100 through the back, the sliding of the switch 200 in the groove 110 will cause the magnet 220 to enter or leave the magnetic field range of the magnetic switch 500, thereby realizing the shaver's on / off state. Compared to the previous method of turning the shaver on by adjusting the back and front of the power switch 200, this method is more convenient and simpler to operate. Correspondingly, when the front of the power switch 200 is connected to the housing 100, the horizontal distance between the magnet 220 and the magnetic switch 500 increases because the power switch 200 separates the magnet 220 from the magnetic field of the magnetic switch 500. At this time, even if the power switch 200 is arbitrarily slid, the shaver cannot be turned on or off. In this state, the user can treat the shaver as a toy and play with the power switch 200. At the same time, this state can also prevent the shaver from being accidentally turned on due to accidental contact with the power switch 200, greatly improving the safety of carrying and storing the shaver.

[0041] Based on the above embodiments, referring to Figure 3 In order to improve the linear stability of the switch 200 when it slides in the slide groove 110, a slide rail 111 is provided in the slide groove 110, and a slide channel 230 is provided on the back of the switch 200. In this way, the slide channel 230 and the slide rail 111 slide together to guide the switch 200 to slide linearly and smoothly.

[0042] Based on the above embodiments, referring to 4, in order to further improve the stability of the magnetic attraction between the switch 200 and the housing 100 via the magnet 220 and to improve the sliding feel of the switch 200 in the slide groove 110, an auxiliary magnet 400 is provided inside the housing 100. The auxiliary magnet 400 is located on the housing 100 and at both ends of the slide groove 110. The auxiliary magnet 400 and the magnet 220 form a magnetic attraction. When the switch 200 slides into place, it will hit the side wall of the slide groove 110, thereby producing a "click" impact sound, improving the feel of the shaver switch.

[0043] In this embodiment, the auxiliary magnet 400 can be disposed in the groove 120 of the housing 100 in the above embodiment, that is, the metal block in the above embodiment can be replaced by the auxiliary magnet 400.

[0044] To further improve the operability of the switch 200, the center line of the auxiliary magnet 400 does not coincide with the center line of the magnet 220 when it slides to the extreme position in the slide groove 110. That is, after the magnet 220 slides to the extreme position in the slide groove 110, there is a gap 'a' between the center line of the auxiliary magnet 400 located at the corresponding end of the slide groove 110 and the center line of the auxiliary magnet 400 located at the corresponding end of the slide groove 110. Utilizing this feature, the following effect can be achieved:

[0045] Because magnet 220 is always subjected to a force aligned with the center line of auxiliary magnet 400 after sliding into position, the switch is always firmly pressed against the end face of the housing. This ensures that the switch 200 will not easily move in the opposite direction; secondly, there will be a crisp knocking sound after sliding; thirdly, the switch 200 and the end face of housing 100 are always firmly pressed together without any gaps; and fourthly, there is magnetic assistance during sliding, so with just a little force, the switch 200 will be automatically attracted into position by the magnet and can be turned on and off, making it easier for users. The above four points effectively improve the user experience, product aesthetics, and stability.

[0046] In this embodiment, the transmission principle of the shaver head output unit is not a major inventive point of this application, so this embodiment only provides a brief description. The shaver head drive mechanism includes a moving shaver head 310, a drive mechanism, and a circuit board 320. The drive mechanism includes a motor 330 and a transmission structure. The motor 330 is electrically connected to the circuit board 320, and the circuit board 320 is electrically connected to a magnetic induction switch 500. After the magnetic induction switch 500 detects a change in the magnetic field, it generates a corresponding electrical signal and transmits it to the circuit board 320. The circuit board 320 controls the motor 330 to start or stop or adjust the output power of the motor 330 according to the corresponding electrical signal. The motor 330 is connected to the moving shaver head 310 through the transmission structure to drive the moving shaver head 310 to move or stop.

[0047] In this embodiment, the swing structure and transmission structure of the corresponding moving cutter head 310 are not the main inventive points of this application, and there are many existing technologies, so they will not be described in detail.

[0048] In this embodiment, the magnetic switch 500 includes any one of a reed switch, a Hall element, and a magnetic sensor. The working principle of the above three magnetic sensors is existing technology, so it will only be described simply. The working principle of the reed switch is as follows: when the magnet 220 is close to the reed switch, the internal contacts close to form a circuit. When the magnet 220 is away from the reed switch, the contacts open and the circuit is broken. The working principle may also be combined with a relay, etc.

[0049] Hall elements, such as Hall effect sensors, can detect changes in magnetic fields and output corresponding electrical signals. These electrical signals can be digital signals, such as switch signals or analog signals. Their working principle may also involve components such as controllers, relays, and circuit boards, which will not be elaborated on here.

[0050] The resistance value of a magnetoresistive sensor changes with the magnetic field. By detecting the change in resistance value, the presence and strength of the magnetic field can be determined. The magnetoresistive sensor can output an analog signal, which is converted into a switching signal by an appropriate signal processing circuit (such as an amplifier and a comparator), thereby controlling the start and stop of the shaver motor 330.

[0051] Based on the above embodiments, the magnetic switch 500 may also involve other components. Any solution that can turn the shaver on or off through a corresponding control unit (such as circuit board 320, microcontroller, etc.) based on the strength or presence of the magnetic field of magnet 220 is acceptable. No further examples will be listed here.

[0052] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
