Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shavers, in particular to a handheld infrared induction shaver. Background Art
[0002] It is known that a razor is a tool for shaving and is an indispensable daily necessity for adult men. For some men who travel frequently, a razor must be carried. Traditional razors use a switch key to control the opening and closing operations. For example, the Chinese utility model patent with authorization announcement number CN217046511U discloses a portable razor, in which the user can insert a finger into the switch exposure port and press the switch button to start shaving. However, after the number of times the switch button is operated exceeds the life span, the switch operation feel and sensitivity decrease, which ultimately affects the product experience and life span. Therefore, there is an electric razor disclosed in the Chinese utility model patent with authorization announcement number CN220446525U, which includes a protective cover, a middle shell and a bottom shell, which are sequentially combined from top to bottom, and a plurality of blade heads arranged on the upper surface of the middle shell; the interior of the bottom shell forms an installation cavity, and the installation cavity is provided with a battery, a motor for driving the blade head to rotate, and a switch circuit. A thermal sensing structure is provided on the side of the bottom shell, and the battery, motor, and switch circuit form a series circuit. The thermal sensing structure is used to control the on and off of the switch circuit. By replacing the switch structure of the existing electric shaver with a thermal sensing structure, it is necessary to rely on the infrared thermal radiation / heat released by the human hand to trigger the thermal sensing structure to close the switch circuit and then start the electric shaver. This better solves the technical problem of the electric shaver being mistakenly triggered by other items when placed in a backpack or suitcase, and improves the safety of the electric shaver. This infrared thermal radiation / heat can trigger the thermal sensing structure to close the switch circuit and then start the electric shaver. For this type of shaver that requires heat, it cannot be started when the heat is insufficient, so sometimes it cannot be started normally, and it is still not accurate enough for users to start, so it is necessary to make improvements.

However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.
[0028] Example 1: See Figure 1 , Figure 2 , Figure 3 and Figure 4A handheld infrared induction shaver comprises a body assembly 1 and a cutter head assembly 2 arranged on the body assembly 1, a first induction connecting piece 3 and a second induction connecting piece 4 are arranged on the body assembly 1, when the cutter head assembly 2 is inserted and installed on the body assembly 1, the first induction connecting piece 3 and the second induction connecting piece 4 are in contact and conductive, the body assembly 1 comprises a shell 11 and the cutter head assembly 2 is installed at one end of the shell 11, a bottom cover 12 is installed at the other end of the shell, the bottom cover 12 and the shell 11 form a chamber 13, a circuit board 14 is installed at the bottom cover 12 position of the chamber 13, a motor 15 and a power supply 16 are arranged in the chamber 13 above the circuit board 14, the output shaft of the motor 15 drives the cutter head assembly 2 through a gear transmission assembly, at least two infrared sensors 17 are arranged in the chamber 13, the circuit board 14 is respectively connected to the first induction connecting piece 3, the motor 15 and the infrared sensor 17, and the power supply 16 provides power to the circuit board 14, the motor 15 and the infrared sensor 17 respectively. When in use, after the infrared sensor 17 senses that the user's hand is holding the shell 11, the circuit board 14 will give a working signal to the motor 15, and the motor 15 will drive the blade assembly 2 to start working through the gear transmission assembly. After the hand leaves the shell 11, the infrared sensor 17 cannot sense the signal and the motor 15 stops working. In this way, the infrared sensor 17 should control the power on and off without pressing the switch, thereby improving the user experience and accuracy.
[0029] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the housing 11 is provided with an infrared emitting hole 111 corresponding to the infrared sensor 17. At this time, when the infrared rays of the human body or a part of the human body (hand) enters the sensing range of the infrared sensor 17, the emitting tube of the infrared sensor 17 will automatically emit infrared rays through the infrared emitting hole 111. When these infrared rays pass through the human body, they will be reflected by the human body back to the receiving tube in the infrared sensor 17. Then, the microcomputer in the integrated circuit in the circuit board 14 receives the infrared signal emitted by the receiving tube in the infrared sensor 17, and sends these signals to the pulse solenoid valve. Then, the valve core in the pulse solenoid valve will control the motor due to the instruction issued by the pulse solenoid valve, and the output shaft on the motor 15 drives the rotating cutter head of the cutting unit in the cutter head assembly 2 to rotate through the gear transmission assembly to achieve the purpose of starting the machine. When the motor 15 adopts an induction motor, this is conducive to achieving the purpose of induction start-up. In this embodiment, two infrared sensors 17 are used, and the two infrared sensors 17 are symmetrically distributed in the cavity 13 of the housing 11, which is conducive to more accurate sensing of a certain part of the user's body (hand) and more conducive to the power-on operation.
[0030] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 1 , Figure 3 and Figure 4 As shown, a bottom plate 131 is provided in the chamber 13, a motor 15 and a power supply 16 are provided on the bottom plate 131, and an infrared sensor 17 is provided on the bottom plate 131. This arrangement is reasonable and more conducive to the installation of the motor 15, the power supply 16 and the infrared sensor 17.
[0031] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 1 As shown, the outer surface of the shell 11 is provided with wave patterns, and the wave patterns are arranged in an inclined shape, which is not only conducive to increasing friction when the user holds it and avoiding the problem of slipping, but also the structure is more novel and beautiful, and is more conducive to meeting the usage needs of ordinary consumer users.

[0033] Embodiment 5: It can be described on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4, such as Figure 3 and Figure 4 As shown, the circuit board 14 is connected to the first sensing connecting piece 3 via the sensing wire 31. This arrangement is reasonable, simple in structure and easy to implement.
[0034] Embodiment 6: It can be described on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4 or Embodiment 5, such as Figure 1 and Figure 3 As shown, the circuit board 14 contains a single-chip microcomputer, and a delay module is prefabricated in the single-chip microcomputer. The delay module can delay the start of the motor 15. In this embodiment, the delay module is preset to 1-2 seconds, so that the motor 15 can have a buffer time, which greatly improves the service life.
