Description

Technical Field

[0001] The present invention relates to the field of household articles, and particularly to a back scratching and back thumping device and a using method thereof. Background Art

[0002] The existing scratching devices mainly include the following types: The first type is a manual linear back scratcher. This device cannot be used by the elderly whose hands and arms cannot be lifted. Moreover, the scratching claws are small, making it difficult to use, with poor convenience and low efficiency. The second type is a manual U-shaped back scratcher. Although this device does not require the elderly to bend their hands over their shoulders, the elderly still need to move their hands up and down significantly, which is laborious and inefficient. The third type is an electric linear back scratcher. This device cannot be used by the elderly whose hands and arms cannot be lifted, and still cannot achieve simultaneous large-range scratching. The fourth type is a seat-type automatic back scratcher. Since it only relies on one scratching claw to achieve large-range scratching of the back, it cannot simultaneously achieve multi-site scratching of the back; it requires the elderly to maintain a state of not relying on the backrest and adjust the distance from the backrest, with poor convenience and comfort.

[0003] The existing integrated scratching and back thumping devices mainly include a manual linear device and an electric integrated scratching and back thumping device, such as Chinese Patent CN 206080994 U, an automatic back scratching device, and CN2259168Y, an automatic back thumping and scratching machine;

[0004] For the above-mentioned back scratchers, since they only rely on one scratching claw to achieve large-range scratching of the back, they cannot simultaneously achieve multi-site scratching of the back; when they work, the horizontal bracket needs to rotate from the vertical position to the horizontal position, which requires the elderly to maintain a state of not relying on the backrest and adjust the distance from the backrest accurately to perform the scratching work, with poor convenience and comfort. For the above-mentioned integrated scratching and back thumping devices, the scratching claws and the hammer heads cannot be displaced and can only operate at a fixed position. It requires the human body to move to cooperate to complete the large-range scratching work. Therefore, we propose a back scratching and back thumping device and a using method thereof. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the present invention provides a back scratching and back thumping device and a using method thereof, enabling the elderly to simultaneously perform large-range scratching and multi-site back thumping of the back in a relaxed and comfortable state, and providing an excellent scratching and back thumping service experience for the elderly.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the present invention provides the following technical solution: An automatic back scratching and back pounding device, comprising a seat, a computer device and an external remote control system. A vertical bracket is fixedly installed on the backrest of the seat. Gear shafts are provided at the upper, middle and lower parts between adjacent two vertical brackets. A lifting motor is fixedly installed at the top of each vertical bracket. The rotating shaft of the upper lifting motor is fixedly connected to the upper gear shaft. The other end of the upper gear shaft is rotatably connected to the vertical bracket. The middle and lower gear shafts are rotatably installed between adjacent two vertical brackets through a rotating shaft. The upper, middle and lower gear shafts are connected by a gear transmission belt. A horizontal base is fixedly installed on the surface of the gear transmission belt. A placing motor is fixedly installed inside the horizontal base. A replacement module is arranged inside the horizontal base. The replacement module is fixedly connected to the output shaft of the placing motor. A T-shaped groove is provided on the replacement module. A replaceable itching scratching claw or a hammer head is arranged on the replacement module. A T-shaped block is integrally formed on one side of the itching scratching claw and the hammer head corresponding to the T-shaped groove. The T-shaped block is clamped with the T-shaped groove. A visual recognition module is fixedly installed at the central position on the side of the replacement module corresponding to the back. The visual recognition module is a camera. The infrared remote control system includes an infrared receiving tube and an infrared remote control. The infrared receiving tube is respectively connected to the lifting motor, the camera, the buzzer and the placing motor. The computer device includes a memory, a processor and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the described automatic scratching and back pounding method is realized.

[0009] A method for using a back scratching and back pounding device, comprising the following steps:

[0010] The first step: Set the number of rotation circles of the lifting motor to be the required number for the horizontal base to just reach the top of the vertical bracket;

[0011] The second step: Replace the itching scratching claw or the hammer head according to the use requirements of scratching and back pounding;

[0012] The third step: When scratching, first place the horizontal base at the bottom of the vertical bracket, turn on the main power supply, and press the corresponding button on the infrared remote control according to the required scratching or itching part;

[0013] The fourth step: The corresponding lifting motor drives the gear shaft to rotate counterclockwise or clockwise, meshes with the gear transmission belt to drive the horizontal base to rise or fall, and the hammer head or the itching scratching claw moves up or down to perform back pounding or scratching.

[0014] Step 5: After reaching the designated part, the camera detects the designated part. When beating the back, if the part is detected to have a wound mark, the buzzer will sound an alarm, otherwise, no sound will be made. When scratching, if the part that the scratching claw is about to touch is detected to have a wound mark, the motor will be placed to rotate 30° counterclockwise to control the scratching claw to retract. After a short period of time, after skipping the wound, the motor will be placed to rotate 30° clockwise to control the scratching claw to extend and continue the scratching work. If the part that the scratching claw is about to touch does not have a wound, the scratching claw will continue to work normally.

[0015] Step 6: When you have finished pounding your back or tickling your itch, press the corresponding end button on the infrared remote control to turn off the main power and the entire device will stop working.

[0016] Preferably, the operation process of the hammer head during the back beating is as follows:

[0017] Step 1: The lifting motor drives the gear shaft to rotate counterclockwise or clockwise, the meshing gear drive belt drives the horizontal base to rise or fall, and the hammer head moves upward. Continue to press the button until the hammer head rises or falls to the specified position;

[0018] Step 2: Place the motor and rotate it 60° counterclockwise to control the hammer head to swing backward, then rotate it 60° clockwise to control the hammer head to swing forward, and the circular rotation of the motor realizes the automatic back-beating function.

[0019] Preferably, the operation process of the itching scratching claw is as follows:

[0020] Step 1: The lifting motor drives the gear shaft to rotate counterclockwise, the meshing gear transmission belt drives the horizontal base to rise, and the scratching claw moves upward;

[0021] Step 2: When the horizontal base rises to the top of the vertical bracket, the lifting motor rotates counterclockwise for the same number of turns, causing the lifting motor to drive the gear shaft to rotate clockwise, and the gear transmission belt meshing with it then drives the horizontal base down, and the scratching claw moves downward;

[0022] Step 3: Repeat the scratching process.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figure 1-7, An automatic back scratching and back pounding device, comprising a seat 1, a computer device and an external remote control system. A vertical bracket 3 is fixedly installed on the backrest of the seat 1. Gear shafts 5 are arranged at the upper, middle and lower parts between two adjacent vertical brackets 3. A lifting motor 7 is fixedly installed at the top of each vertical bracket 3. The rotating shaft of the upper lifting motor 7 is fixedly connected to the upper gear shaft 5. The other end of the upper gear shaft 5 is rotatably connected to the vertical bracket 3. The middle and lower gear shafts 5 are rotatably installed between two adjacent vertical brackets 3 through rotating shafts. The upper, middle and lower gear shafts 5 are connected by a gear transmission belt 4. A horizontal base 8 is fixedly installed on the surface of the gear transmission belt 4. A placing motor 2 is fixedly installed inside the horizontal base 8. A replacement module 10 is arranged inside the horizontal base 8. The replacement module 10 is fixedly connected to the output shaft of the placing motor 2. A T-shaped groove is formed on the replacement module 10. A replaceable itching scratching claw 6 or a hammer head 9 is arranged on the replacement module 10. A T-shaped block is integrally formed on one side of the itching scratching claw 6 and the hammer head 9 corresponding to the T-shaped groove. The T-shaped block is clamped with the T-shaped groove. A visual recognition module is fixedly installed at the central position on the side of the replacement module 10 corresponding to the back. The visual recognition module is a camera. The infrared remote control system includes an infrared receiving tube and an infrared remote controller 11. The infrared receiving tube is respectively connected to the lifting motor 7, the camera, the buzzer and the placing motor 2. The computer device includes a memory, a processor and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, an automatic scratching and back pounding method is realized.

[0036] Working buttons of the infrared remote controller 11: Button start1, button start2, button start3, and button start4 control the start operation of the first, second, third, and fourth lifting motors 7 respectively from left to right, control the rising or falling of the itching scratching claw 6 or the hammer head 9, and the turning on of the corresponding camera. Button over1, button over2, button over3, and button over4 control the end operation of the first, second, third, and fourth lifting motors 7 and the camera respectively.

[0037] The buttons down1, down2, down3, and down4 respectively control the first, second, third, and fourth lifting motors 7 to rotate clockwise at a small angle, realizing a small drop of the scratching claw 6 or the hammer head 9, and controlling the activation of the buzzer and the camera; the buttons up1, up2, up3, and up4 respectively control the first, second, third, and fourth lifting motors 7 to rotate counterclockwise at a small angle, realizing a small rise of the scratching claw 6 or the hammer head 9, and controlling the activation of the buzzer and the camera. The buttons startA, startB, startC, and startD respectively control the first, second, third, and fourth placement motors 2 to start operating, and control the buzzer and the camera to turn off, realizing the back-pounding function buttons; the buttons overA, overB, overC, and overD respectively control the first, second, third, and fourth placement motors 2 inside the four horizontal bases 8 to end the operation from the left side to the right side inside, stopping the back-pounding.

[0038] Visual recognition module: Detect whether there are wounds on the back skin through the camera above the horizontal base 8 and feedback data. Machine vision (image preprocessing) part: The camera takes pictures of the operable area of the scratching claw, so that the camera can smoothly capture the working area and the scratching claw mechanism. After graying the image, it is used as input, and a target detection algorithm or a template matching algorithm (such as the target detection algorithm: YOLOv5, or directly use the template matching method of OpenCV, such as: TM_SQDIFF_NORMED) is adopted to perform target detection (or template matching) on the scratching claw mechanism. After capturing the spatial position, combined with OpenCV (Open Source Computer Vision Library), ROI (region of interest) partitioning is performed, and the areas near the two scratching claws are boxed and set as the ROI area. The preprocessing is completed.

[0039] Machine vision (scar detection) part:

[0040] Process the B component, convert it into an image in the frequency domain, and perform Gaussian convolution on it. Then convert the convolved image back to a spatial domain image. Subsequently, perform a difference operation on the B component image and the processed B component image using the operator sub_image. Finally, the lines_gauss can be called to extract the imprints. To avoid the influence of the border on the lines_gauss, the image is further intercepted, and the four sides are removed using erosion_rectangle1.

[0041] A method for using a back scratching and pounding device includes the following steps:

[0042] Automatic scratching implementation method:

[0043] Set the number of rotation cycles of the lifting motor 7 to be the number required for the horizontal base 8 to just reach the top of the vertical bracket 3.

[0044] First, place the horizontal base 8 at the bottom of the vertical bracket 3, turn on the main power supply, and press the corresponding button (button start1, button start2, button start3, button start4) on the infrared remote control 11 according to the itchy area required.

[0045] The corresponding lifting motor 7 drives the gear shaft 5 to rotate counterclockwise, and the meshing gear belt 4 drives the horizontal base 8 to rise, and the backscratcher claw 6 moves upward.

[0046] During the upward movement of the backscratcher claw 6, the camera on the horizontal base 8 rises with the horizontal base 8. If it detects that the area about to be contacted by the backscratcher claw 6 has a wound, the placement motor 2 rotates counterclockwise by 30° to control the backscratcher to retract. When it detects that the wound has been skipped, the placement motor 2 rotates clockwise by 30° to control the backscratcher to extend and continue the scratching work. If the area about to be contacted by the backscratcher claw 6 does not have a wound, the backscratcher claw 6 works continuously normally.

[0047] When the horizontal base 8 rises to the top of the vertical bracket, the lifting motor 7 rotates counterclockwise by the same number of cycles, so that the lifting motor 7 drives the gear shaft 5 to rotate clockwise, and the meshing gear belt 4 drives the horizontal base 8 to descend accordingly, and the backscratcher claw 6 moves downward.

[0048] During the downward movement of the backscratcher claw 6, the camera on the horizontal base 8 descends with the horizontal base 8 and simultaneously detects the back skin.

[0049] If it detects that the area about to be contacted by the backscratcher claw 6 has a wound mark, the placement motor 2 rotates counterclockwise by 30° to control the backscratcher claw 6 to retract. When the wound has been skipped after a short period of time, the placement motor 2 rotates clockwise by 30° to control the backscratcher claw 6 to extend and continue the scratching work. If the area about to be contacted by the backscratcher claw 6 does not have a wound, the backscratcher claw 6 works continuously normally.

[0050] During the up and down movement of the backscratcher claw 6, if the corresponding end button for each backscratcher claw 6 is not pressed on the infrared remote control 11, the backscratcher claw 6 works continuously. If the corresponding end button (button over1, button over2, button over3, button over4) is pressed, then this backscratcher claw 6 stops working.

[0051] When the horizontal base 8 reaches the bottom of the vertical bracket, if the main power supply is not turned off, the lifting motor 7 continues to operate, driving the back scratcher claw 6 to rise again. When the horizontal base 8 reaches the top of the vertical bracket, if the main power supply is not turned off, the lifting motor 7 continues to operate, driving the back scratcher claw 6 to descend again, thus realizing the reciprocating and continuous operation of the back scratcher.

[0052] Turn off the main power supply, and the entire device stops working.

[0053] Method for realizing automatic back pounding:

[0054] When switching between scratching and back pounding, stop the operation of each motor, remove the back scratcher claw 6 or the hammer head 9 placed on the placement motor 2, and replace it with the hammer head 9 or the back scratcher claw 6. At the same time, the number of hammer heads 9 installed on each replacement module 10 can be determined according to the range of the back pounding to be performed.

[0055] Turn on the main power supply, and press the corresponding small - amplitude descent or ascent buttons (button down1, button down2, button down3, button down4 or button up1, button up2, button up3, button up4) for the placement motor 2 and the lifting motor 7 on the infrared remote control 11 according to the back - pounding position required.

[0056] The corresponding lifting motor 7 drives the gear shaft 5 to rotate counter - clockwise or clockwise, meshing with the gear transmission belt 4 to drive the horizontal base 8 to rise or fall, and the hammer head 9 moves upward. Continue to press the button until the hammer head 9 rises or falls to the specified position.

[0057] After reaching the specified position, the camera detects the specified position. If a wound mark is detected at the position, the buzzer sounds an alarm. Otherwise, no sound is emitted.

[0058] Press the corresponding start button (button startA, startB, startC, startD), the buzzer and the camera are turned off. The corresponding placement motor 2 first rotates counter - clockwise by 60°, controlling the hammer head 9 to swing backward, and then rotates clockwise by 60°, controlling the hammer head 9 to swing forward. The cyclic rotation of the placement motor 2 realizes the automatic back - pounding function.

[0059] During the cyclic operation of the hammer head 9, if the corresponding end button for each hammer head 9 is not pressed on the infrared remote control 11, the hammer head 9 continues to work. If the corresponding end button (button overA, button overB, button overC, button overD) is pressed, then this hammer head 9 stops working.

[0060] If the main power supply is not turned off, the hammer head 9 operates normally. If the main power supply is turned off, the entire device stops working.

[0061] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
