Description

Technical Field

[0001] This invention relates to an automatic control method for electric shavers, and more particularly to an intelligent control method that combines prompting for shaving effect and safe shaving function. Background Technology

[0002] Painful and reddened skin after shaving with an electric shaver may be due to improper force. Therefore, high-speed shavers typically have stronger cutting power and can shave faster, but they can also cause skin irritation and discomfort. People with thick, coarse beards may need a higher speed shaver for a faster shave, while those with sensitive skin should choose a lower speed setting to reduce over-irritation.

[0003] Furthermore, when using an electric shaver to shave, it's necessary to determine whether the face is clean using either a mirror or by touch. The former is inconvenient as it requires a mirror for confirmation, while the latter, relying on touch, is inaccurate and can easily result in an incomplete shave. Summary of the Invention

[0004] This invention designs an intelligent control method that combines prompting for shaving and safe shaving functions. The technical problem it solves is that existing electric shavers are complicated to achieve a clean shave and there is a risk of skin damage from improper shaving.

[0005] To solve the aforementioned technical problems, the present invention adopts the following solution:

[0006] A smart control method that combines shaving effect enhancement and safe shaving functions includes the following steps: Step 1: The user holds the electric shaver and activates the handle pressure sensor on the handle. The control unit starts the camera to perform the first image acquisition based on the activation signal of the handle pressure sensor; Step 2: The camera acquires facial information, including images of the left cheek, right cheek, upper jaw, and lower jaw, and acquires beard distribution information in the above areas; Step 3: The electric shaver head contacts the skin, activating the shaving pressure sensor. The control unit starts the motor based on the activation signal of the shaving pressure sensor, causing the shaver head to work; Step 4: When the electric shaver head... Once the head is removed from the skin, the control unit loses the sensing signal from the shaving pressure sensor, stops the motor, and activates the camera to capture a second image. Step 5: The control unit compares the first and second images to determine if the beard distribution information from the first image is present in the second image. If it is confirmed that the beard distribution information is present, the control unit activates the corresponding light strip for the corresponding area of ​​the face to flash, prompting the user to clean the beard in that area again. If it is confirmed that the beard distribution information is not present, the control unit turns off or keeps the corresponding light strip for the corresponding area of ​​the face off. Step 6: Repeat steps 3-5 until all light strips are off.

[0007] Preferably, there are three cameras in step 2: the first camera captures image information of the left cheek, the second camera captures image information of the right cheek, and the third camera captures image information of the upper and lower jaws.

[0008] Preferably, when the cameras collect information in steps 2 and 4, the user holds the electric shaver head directly in front of their face and provides a better collection angle for the three cameras by shaking their head left and right and up and down.

[0009] Preferably, in step 3, when the shaving pressure sensor senses the T1 pressure value generated by the contact between the shaving head and the user's skin, the control unit starts the motor, and the motor makes the rotation speed of the shaving head V1; when the shaving pressure sensor senses the T2 pressure value generated by the contact between the shaving head and the user's skin, T2>T1, the control unit increases the rotation speed of the shaving head to V2 to improve the shaving effect, V2>V1; when the shaving pressure sensor senses the T3 pressure value generated by the contact between the shaving head and the user's skin, T3>T2, the control unit reduces the rotation speed of the shaving head to V1 to protect the user's skin.

[0010] Preferably, when the top of the shaving head contacts the skin, it causes the shaving head to move downwards and activate the shaving pressure sensor. The moving shaving head drives the cover to move via a transmission mechanism and cover the camera, preventing water, oil, or dirt on the face from sticking to the camera lens during shaving.

[0011] Preferably, in step 5, when the control unit compares the first image with the second image, it identifies the area of ​​facial change in the second image as the shaved beard area S1 in the first image. The shape and color of the beard area S1 in the first image are used to further determine whether other areas in the second image are areas that need to be shaved, thus avoiding misjudgment.

[0012] Preferably, there are three light bars in step 5: the first light bar displays the shaving status of the left cheek, the second light bar displays the shaving status of the right cheek, and the third light bar displays the shaving status of the upper and lower jaws.

[0013] Preferably, each lamp body has multiple LED beads arranged in a straight line, and the multiple beads can be lit in a specific order; if the beads of the first light strip light up sequentially from top to bottom, it indicates that the upper part of the left cheek is not clean; if the beads of the first light strip light up sequentially from bottom to top, it indicates that the lower part of the left cheek is not clean; if all the beads of the first light strip are lit, it indicates that both the upper and lower parts of the left cheek are not clean. If the beads of the second light strip light up sequentially from top to bottom, it indicates that the upper part of the right cheek is not clean; if the beads of the second light strip light up sequentially from bottom to top, it indicates that the lower part of the right cheek is not clean; if all the beads of the second light strip light are lit, it indicates that both the upper and lower parts of the right cheek are not clean. If the beads of the third light strip light up sequentially from top to bottom, it indicates that the upper jaw is not clean; if the beads of the third light strip light up sequentially from bottom to top, it indicates that the lower jaw is not clean; if all the beads of the third light strip light are lit, it indicates that both the upper and lower jaws of the right cheek are not clean.

[0014] Preferably, the control unit is a mobile terminal, which collects data and controls sensors, motors, cameras, and light strips via wireless transmission.

[0015] The present invention relates to an intelligent electric shaver, characterized in that it is equipped with the aforementioned intelligent control method.

[0016] This intelligent control method, which combines shaving effect enhancement and safe shaving functions, has the following beneficial effects:

[0017] (1) The method of the present invention can not only achieve the function of safe shaving, but also automatically identify and indicate whether the user has shaved clean, without the need for a mirror or the user to touch and check, thus increasing the shaving experience.

[0018] (2) The present invention informs the user of the force applied by a pressure sensor, and increases the speed of the blade head to accelerate shaving when the force is appropriate, while reducing the speed of the blade head to avoid damaging the skin and causing redness and swelling when the force is too great.

[0019] (3) The present invention can also make the moving blade head drive the cover to move through the transmission mechanism and cover the camera, so as to prevent water, oil or dirt on the face from sticking to the lens of the camera when shaving. Attached Figure Description

[0027] The following is combined Figures 1 to 4 The present invention will be further described as follows:

[0028] like Figure 1 As shown, the present invention provides an intelligent control method that combines shaving effect prompts and safe shaving functions, comprising the following steps: Step 1: The user holds the electric shaver and activates the handle pressure sensor on the handle. The control unit starts the camera to perform the first image acquisition based on the activation signal of the handle pressure sensor; Step 2: The camera acquires facial information, including images of the left cheek, right cheek, upper jaw, and lower jaw, and acquires beard distribution information in the above areas; Step 3: The shaver head contacts the skin, activating the shaving pressure sensor. The control unit starts the motor based on the activation signal of the shaving pressure sensor, causing the shaver head to work; Step 4: When the shaver head leaves the skin... When the skin loses the sensing signal from the shaving pressure sensor, the control unit stops the motor and activates the camera to capture a second image. Step 5: The control unit compares the first and second images to determine if the beard distribution information from the first image is present in the second image. If it is confirmed that the beard distribution information from the first image is present, the control unit activates the corresponding light strip for the corresponding area of ​​the face to flash, prompting the user to clean the beard in that area again. If it is confirmed that the beard distribution information is not present, the control unit turns off or keeps the corresponding light strip for the corresponding area of ​​the face off. Step 6: Repeat steps 3-5 until all the light strips are off, indicating that the facial shaving has met the predetermined requirements.

[0029] In step 2, there are three cameras: the first camera 41 captures image information of the left cheek, the second camera 42 captures image information of the right cheek, and the third camera 43 captures image information of the upper and lower jaws.

[0030] In steps 2 and 4, when the cameras are collecting information, the user should hold the electric shaver head directly in front of their face and move their head left and right and up and down to provide better shooting angles for the three cameras.

[0031] In step 3, when the shaving pressure sensor senses the T1 pressure value generated by the contact between the shaving head and the user's skin, the control unit starts the motor, and the motor makes the rotation speed of the shaving head V1; when the shaving pressure sensor senses the T2 pressure value generated by the contact between the shaving head and the user's skin, T2 > T1, the control unit increases the rotation speed of the shaving head to V2 to improve the shaving effect, V2 > V1; when the shaving pressure sensor senses the T3 pressure value generated by the contact between the shaving head and the user's skin, T3 > T2, the control unit reduces the rotation speed of the shaving head to V1 to protect the user's skin.

[0032] When the tip of the shaving head contacts the skin, it moves downwards to activate the shaving pressure sensor. The moving shaving head then moves the cover via a transmission mechanism and covers the camera, preventing water, oil, or dirt from sticking to the camera lens during shaving.

[0033] In step 5, when the control unit compares the first image with the second image, it identifies the area of ​​facial change in the second image as the shaved beard area S1 in the first image. Based on the shape and color of the beard area S1 in the first image, it further determines whether other areas in the second image are areas that need to be shaved, thus avoiding misjudgment.

[0034] There are three light bars in step 5. The first light bar 31 shows the shaving status of the left cheek, the second light bar 32 shows the shaving status of the right cheek, and the third light bar 43 shows the shaving status of the upper and lower jaws.

[0035] Each light unit contains multiple LED beads arranged in a straight line, and these beads can be lit in a specific order. If the beads in the first light strip 31 light up sequentially from top to bottom, it indicates that the upper part of the left cheek is not clean; if the beads in the first light strip 31 light up sequentially from bottom to top, it indicates that the lower part of the left cheek is not clean; if all the beads in the first light strip 31 are lit, it indicates that both the upper and lower parts of the left cheek are not clean. Similarly, if the beads in the second light strip 32 light up sequentially from top to bottom, it indicates that the upper part of the right cheek is not clean; if the beads in the second light strip 32 light up sequentially from bottom to top, it indicates that the lower part of the right cheek is not clean; if all the beads in the second light strip 32 are lit, it indicates that both the upper and lower parts of the right cheek are not clean. Likewise, if the beads in the third light strip 33 light up sequentially from top to bottom, it indicates that the upper jaw is not clean; if the beads in the third light strip 33 light up sequentially from bottom to top, it indicates that the lower jaw is not clean; if all the beads in the third light strip 33 are lit, it indicates that both the upper and lower jaw of the right cheek are not clean.

[0036] The control unit is a mobile terminal, which collects data and controls sensors, motors, cameras, and light strips via wireless transmission. Mobile terminals include smartphones and tablets.

[0037] like Figure 2As shown, the electric shaver 1 has three blades 2 on its shaving panel: a first blade 21, a second blade 22, and a third blade 23. The first blade 21, the second blade 22, and the third blade 23 are arranged in a triangle and can rotate under the action of a motor to shave. Each blade 2 is set in a mounting slot and can move downward a certain distance and act on the shaving pressure sensor 5 at the bottom.

[0038] The electric shaver 1 has a first camera 41, a second camera 42 and a third camera 43 on its shaving panel. The first camera 41 captures image information of the left cheek, the second camera 42 captures image information of the right cheek, and the third camera 43 captures image information of the upper jaw and lower jaw.

[0039] The electric shaver 1 also has a first light strip 31, a second light strip 32, and a third light strip 43 on its shaving panel. The first light strip 31 displays the shaving status of the left cheek, the second light strip 32 displays the shaving status of the right cheek, and the third light strip 43 displays the shaving status of the upper and lower jaws. The three light strips form a "V" shape in the center area of ​​the shaving panel.

[0040] like Figure 3 As shown, the shaving area on the face is divided into four regions: left cheek A, right cheek B, upper jaw C, and lower jaw D. Different cameras capture images of the left cheek A, right cheek B, upper jaw C, and lower jaw D, respectively.

[0041] like Figure 4 As shown, the moving blade drives the cover to move via a transmission mechanism, covering and protecting the camera 4. There are many types of transmission mechanisms, too numerous to list. They could be... Figure 4 The structure in.

[0042] The transmission structure is a lever 61. One end of the lever 61 is raised and a return spring 64 is provided between it and the fixed end. The other end of the lever 61 is connected to an elastic cover 62. The elastic cover 62 has a through hole 63. When the blade head 2 is not moving downward, the through hole 63 is located above the camera 4 for easy image acquisition. When the blade head 2 is moved downward by the skin, the blade head 2 presses one end of the lever 61, causing the other end of the lever 61 and the elastic cover 62 to also move. Ultimately, the through hole 63 is misaligned with the camera 4, causing the elastic cover 62 to block the through hole 63. When the blade head 2 is no longer in contact with the face, the blade head moves upward under the action of the lifting return spring. The lever 61 is reset by the return spring 64, and the through hole 63 of the elastic cover 62 moves back above the camera 4, opening the channel for image acquisition.

[0043] There are many types of transmission structures, including levers and gears.

[0044] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
