[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Embodiment 1:

[0050] A massage chair based on the principle of airflow impacting acupuncture points, as shown in the attached Figure 1-5 , 8 and 9:

[0051] like Figure 1-2 As shown, a hard or flexible guide rail 300 is installed on the seat body 100, and the massage movement 200 moves along the track of the guide rail 300 under the guidance of the guide rail 300. This is the prior art in the field and will not be described in detail.

[0052] like Figure 3-5 As shown, a dense rectangular array of spring pins 205 is provided on one side of the massage movement 200, and each spring pin 205 has an air flow channel; Figure 5 As shown, the spring ejector 205 includes a fixed ejector tube 2051, a movable ejector tube 2052, a spring 2053 and an identification piece 2054. The fixed ejector tube 2051 is relatively fixed to the massage movement 200, the movable ejector tube 2052 is relatively sleeved on the outside of the fixed ejector tube 2051 and is airtightly slidably matched, the spring 2053 is arranged between the movable ejector tube 2052 and the fixed ejector tube 2051, and the elastic force of the spring 2053 pushes the movable ejector tube 2052 to move away from the fixed ejector tube 2051; an identification piece 2054 is arranged on the same side of a row of movable ejector tubes 2052 at the outermost periphery (either side of the upper, lower, left or right), and under normal conditions, all the identification pieces 2054 form a straight line;

[0053] The identification piece 2054 can be made of a material with fluorescent properties, and can glow in the dark to be photographed and identified by the camera assembly 207, and to be distinguished from the spring ejector pin 205; the distance between two adjacent identification pieces 2054 is small.

[0054] A camera assembly 207 with a visual recognition function is installed on the massage movement 200. The camera assembly 207 is used to photograph the outermost row of spring pins 205, so as to collect the contour lines composed of all the identification parts.

[0055] The air hood 206 is hollow inside and has one side open. The inner cavity of the air hood 206 is connected to an external air source, which can be compressed air. Figure 4As shown, a portion of the isolation zone 202 is located between the opening of the air hood 206 and the fixed ends of all the spring ejector pins 205 (fixed ejector tubes 2051), an elastic seal is provided at the edge of the air hood 206 to improve the sealing between the isolation zone 202, and an elastic seal is provided at the fixed end of the spring ejector pin 205 to improve the sealing between the isolation zone 202.

[0056] The isolation belt 202 is provided with multiple groups of different types of pore groups 203 along its length direction. One group of pore groups 203 includes multiple groups of pores. One group of pore groups 203 corresponds to the distribution of acupuncture points of a human body shape. The pore groups 203 can roughly correspond to the acupuncture points without being very precise. Figure 3 As shown, the red curve box represents an arrangement of the pore group 203.

[0057] like Figure 2 , 3 As shown in FIG. 6 , two types of guide wheel groups 201 are provided. The guide wheel group 201 is used to drive the isolation belt 202 to move, and can control one group of air hole groups 203 to move to between the opening side of the air cover 206 and the spring ejector pins 205 of the array.

[0058] A thin rubber layer may be provided on both the inner and outer sides of the isolation belt 202 to improve the sealing performance.

[0059] Working principle:

[0060] The user lies on the seat body 100 with his back against the spring pins 205 of the array. The spring pins 205 change according to the back shape of the user. The outermost row of spring pins 205 captured by the camera assembly 207 is as follows: Figure 8 As shown, the captured image is processed to extract all identification parts 2054 therein, and all identification parts 2054 extracted after image processing are combined into contour lines ( Fig. 9 The black line) is mapped to a two-dimensional coordinate to form a contrast line. The two-dimensional coordinate presets an outline line composed of all the identification elements 2054 in an unused state ( Fig. 9 The red lines in the figure form the reference lines.

[0061] The identification member 2054 is mapped as a line parallel to the X-axis in the two-dimensional coordinates; the movement direction of the movable top tube 2052 relative to the fixed top tube 2051 is mapped as a line parallel to the Y-axis in the two-dimensional coordinates.

[0062] The part of the comparison line that overlaps with the reference line is removed, and the offset distance H of the remaining lines on the Y axis is calculated and the average value is obtained. The pressure of the external compressed air is controlled according to the obtained average value. The larger the offset on the Y axis, the heavier the user is and the greater the airflow can be. The opposite is true.

[0063] The part of the comparison line that overlaps with the reference line is removed, and the length distance L of the two end points of the remaining line is calculated. According to whether the length distance L falls within the corresponding interval, the corresponding guide wheel group 201 is controlled to drive the isolation belt 202 to move, so that a group of air hole groups 203 corresponding to this interval moves to between the opening side of the air cover 206 and the spring ejector pin 205 of the array.

[0064] The external air source is delivered to the air hood 206, and the isolation belt 202 closes the open side of the air hood 206. The compressed air inside the air hood 206 is delivered to the air flow channels of the corresponding several spring ejectors 205 through the air hole group 203 opened on the isolation belt 202 between the open side of the air hood 206 and the spring ejectors 205 of the array. The air flow ejected by these several spring ejectors 205 is roughly aimed at a certain acupuncture point of the user.

[0065] The amount of compressed air at the same time is limited. If too many air flow channels of the spring ejector pins 205 are in the open state, the pressure of the air flow ejected from the spring ejector pins 205 will be reduced, thereby reducing the massage effect.

[0066] Embodiment 2:

[0067] The present invention includes all the contents of the first embodiment, except that:

[0068] A plurality of standard trace line groups with different shapes formed by users pressing against the spring ejector pins 205 can be preset, and each preset standard trace line group corresponds to a group of air hole groups 203 .

[0069] When in use, the contour lines formed by the user are collected and compared with all standard trace line groups for similarity, and the standard trace line group with the highest similarity is screened out, so as to move the corresponding air hole group 203 to between the opening side of the air cover 206 and the spring ejector pin 205 of the array.

[0070] The details are as follows: Determine the similarity based on the error S;

[0071] ;

[0072] in, The first The Y-axis coordinate of each identification element is mapped in the two-dimensional coordinate system; is the kth standard trace line group The Y-axis coordinate of each identification element is preset in the two-dimensional coordinate system.

[0073] The smaller the error S is, the more similar they are.

[0074] The above settings can greatly reduce the difficulty of similarity judgment and improve the efficiency and accuracy of visual recognition.

[0075] Embodiment three:

[0076] Contains all the contents of Embodiment 1 or 2, except that:

[0077] In order to improve the air tightness between the fixed end of the spring ejector pin 205 and the isolation zone 202, a first magnetic member is arranged at the periphery of the air flow channel at the fixed end of the spring ejector pin 205, and the first magnetic member can be made of iron material;

[0078] like Figure 7 As shown, a second magnetic member 2021 is arranged around the pores in the pore group 203 of the isolation zone 202. The second magnetic member 2021 can be a thin electromagnet (electromagnetic sheet). All second magnetic members 2021 of the same pore group 203 correspond to two groups of second conductive parts 2022. The second conductive parts 2022 are arranged in the isolation zone 202 near the corresponding pore group 203. The second conductive parts 2022 of different pore groups 203 are arranged differently in the isolation zone 202 along the guide axis 2011.

[0079] The guide wheel assembly 201 has a self-powered guide shaft 2011, on which a plurality of first conductive parts 2012 are arranged. The plurality of first conductive parts 2012 are arranged in at least two groups, and one group of first conductive parts 2012 is distributed in a circle along the axis of the guide shaft 2011 in a spiral.

[0080] Working principle:

[0081] When a group of air hole groups 203 are moved to between the opening side of the air cover 206 and the spring ejector pins 205 of the array, the guide shaft 2011 is driven by its own power to rotate to a set angle. At this time, the first conductive part 2012 on the guide shaft 2011 just abuts against the corresponding second conductive part 2022; the external power supply supplies power to the second magnetic part 2021 between the opening side of the air cover 206 and the spring ejector pins 205 of the array through the first conductive part 2012 and the second conductive part 2022. The second magnetic part 2021 is energized to generate magnetism, which is attracted to the first magnetic part to improve the sealing.

[0082] Whether the second magnetic member 2021 is powered on can be used as feedback to determine whether the corresponding air hole group 203 has accurately moved to between the opening side of the air cover 206 and the spring ejector pins 205 of the array.
