The lower end of the nozzle body 2-8 is connected to a water inlet hose 2-7, and the upper end of the nozzle body is a water outlet, which sprays water outward; there is a certain distance between the inner frame 2-12 and the outer frame 2-10, and the inner frame can rotate around the X-axis relative to the outer frame; a bridge frame 2-11 is also arranged in the outer frame 2-10, and there is a certain distance between the bridge frame 2-11 and the outer frame 2-10, and the bridge frame can rotate around the Y-axis relative to the outer frame, and the Y-axis and the X-axis are perpendicular to each other, and the bridge frame 2-11 includes two parallel and spaced bridge arms 2-111, and the two bridge arms 2-111 cross over the top of the inner frame 2-12, and the bridge frame There is a certain distance between the bridge frame 2-11 and the inner frame 2-12, and the rotational movement of the bridge frame around the Y axis and the rotational movement of the inner frame around the X axis are independent of each other to a certain extent and do not interfere with each other; the lower part 2-82 of the nozzle body is movably or rotationally connected with the inner frame 2-12, and the upper part 2-81 of the nozzle body passes through the inner frame and passes through between the two bridge arms 2-111 of the bridge frame. The distance between the two bridge arms matches the upper part of the nozzle body, so that when the bridge frame rotates around the Y axis, it will drive the nozzle body to rotate together. Under the drive of the driving device, the nozzle body can rotate around both the X axis and the Y axis, and the two do not interfere with each other. A limiting device 2-9 is also fixedly arranged on the outer frame 2-10, and a limiting hole is opened on the limiting device. The upper part of the nozzle body passes through the limiting hole. The specific shape of the limiting device 2-9 can be a limiting ring or an elliptical ring. In this way, the driving device can control the movement trajectory of the nozzle body from the program, and the limiting device further limits the movement range of the nozzle body from the mechanical point of view.

[0022] More specifically, the outer frame 2-10 and the inner frame 2-12 are both rectangular, the inner frame is located at the center of the outer frame, and the sides of the outer frame and the inner frame are initially parallel to each other. Bearings are provided on the two opposite side walls of the outer frame 2-10, and the bearings are equipped with X-axis direction rotating shafts 2-13. The inner ends of the two X-axis direction rotating shafts 2-13 are respectively fixedly connected to the two opposite side outer walls of the inner frame, and the outer end of one of the X-axis direction rotating shafts vertically extends to the outside of the side of the outer frame and is connected to the driving device stepper motor 2-2. Bearings are also provided on the other two opposite side walls of the outer frame 2-10, and the bearings are equipped with Y-axis direction rotating shafts 2-14. The inner ends of the two Y-axis direction rotating shafts are respectively fixedly connected to the two ends of the bridge frame, and the outer end of one of the Y-axis direction rotating shafts vertically extends to the outside of the side of the outer frame and is connected to the driving device stepper motor 1 2-1. Motor 1 and Motor 2 can be directly connected to the X-axis direction rotating shaft and the Y-axis direction rotating shaft, respectively, or can be indirectly connected through a reducer or a gear set. Figure 1-2 The figure shows that the motor 1 is meshed with the rotating shaft in the X-axis direction through a bevel gear, and the motor 2 is meshed with the rotating shaft in the Y-axis direction through a bevel gear, so that the nozzle and the motor can be separated in space for easy separation of dry and wet. The stepper motor 2-1 drives the bevel gear 4 2-6 to rotate, and then drives the bridge frame 2-11 to rotate left and right around the Y axis through the bevel gear 2-5 (see Figure 2 As shown in the orientation, the two arms 2-111 of the bridge frame clamp the nozzle 2-8 and rotate synchronously, and the maximum rotation angle is determined by the limit ring 2-9; the stepper motor 2-2 drives the bevel gear 2-4 to rotate, and then drives the inner frame 2-12 to rotate forward and backward around the X-axis through the bevel gear 1 2-3, and the nozzle 2-8 limited by the two arms of the bridge frame 2-11 rotates synchronously, and the maximum rotation angle is determined by the limit ring 2-9; the nozzle 2-8 can rotate forward and backward while rotating left and right under the drive of the driving device, so that when the nozzle sprays water, the effective area of ​​the water column sprayed by the nozzle 2-8 is no longer a point but can have a variety of changes, such as a line or a surface area, the surface area can be a circular surface or an elliptical surface, which is determined by the control program and the shape of the limit device. The rotating nozzle can be applied to a hydrotherapy massage device.

[0023] Embodiment 1

[0024] A hydrotherapy massage bed, such as Figure 3-6As shown, the bed body 1 and the control panel are included. The bed body includes a bracket 12. A waterproof jacket 13 is provided on the outer surface of the bracket 12. The waterproof jacket can be a soft board made of silicone. A pillow 11 is provided on the waterproof jacket 13. A water tank 4, a water pump and an electrical control box 3, a water pipe, an electric ball valve, and four rotating nozzles 2 are provided inside the bracket 12. The water tank 4 is filled with water. The human body lies on the waterproof jacket and the buoyancy of the water is used to support the human body. Two nozzles are provided on the back of the human body, and one nozzle is provided on each of the left and right lower limbs of the human body. The nozzle body and the outer frame are provided in the water tank. The water sprayed by the nozzle falls directly into the water tank. The outer frame is fixedly connected to the water tank. The driving device is provided below the bottom plate 41 of the water tank and is fixedly connected to the bracket to prevent the driving motor from contacting with water. The output shaft seal of the driving motor passes through the bottom plate of the water tank and enters the inside of the water tank. The water pump and the electrical control box are also provided below the water tank. The water outlet pipe 6 of the water tank provides water source for the water pump. After being pressurized by the water pump, water source with a certain pressure is provided to the nozzle through the water inlet pipe 1 7. Four electric ball valves 5 are arranged on the water inlet pipe 1 7. Each rotating nozzle is controlled by an electric ball valve to supply water. The water pump, electrical control box, electric ball valve and driving device are all electrically connected to the control panel.

[0025] Embodiment 2 A dry hydrotherapy massage chair, such as Figure 7 As shown, it includes a seat 9 and a control panel. A waterproof jacket is provided on the outer cover of the seat 1. A water tank 4, a water pump and an electrical control box 3, a water outlet pipe 6, a water inlet pipe 1 7 and a water inlet pipe 2 8, four electric ball valves 6, and four rotating nozzles 2 are provided inside the seat. Two rotating nozzles 2 are provided at the backrest of the seat, and two rotating nozzles 2 are provided at the leg of the seat. The water outlet pipe 6 is used to supply water to the water pump 3. The water inlet pipe 1 7 and the water inlet pipe 2 8 are both connected to the water pump to bear the water outlet of the water pump and the water inlet of the nozzle. Two electric ball valves 5 are arranged in parallel on the water inlet pipe 1 7, and two electric ball valves 6 are arranged in parallel on the water inlet pipe 2 8. A rotating nozzle is connected to the rear end of each electric ball valve. Each rotating nozzle 2 is controlled by an electric ball valve 6 to supply water. The water pump and the electrical control box 3, the electric ball valve 6, and the rotating nozzle 2 are all electrically connected to the control panel. Compared with a massage bed, a hydrotherapy massage chair can reduce the floor space and facilitate sitting for hydrotherapy massage.

[0026] The method of using the hydrotherapy massage bed and the massage chair is basically the same: first fill the water tank with water, and after the water filling is completed, the person lies on the bed or sits on the chair, turns on the power, operates the control panel, and the water pump will pump water from the water tank 4 through the electric ball valve to the rotating nozzle 2 for spraying. The frequency converter in the water pump and the electrical control box 3 can control the strength of the water spray, and the stepper motor of the rotating nozzle 2 can control the swing angle of the nozzle to control the massage area. The electric ball valve can control whether the rotating nozzle sprays water or not. Compared with the traditional dry hydrotherapy massage, the present invention uses fewer nozzles, but the massage area is not reduced. Four rotating nozzles are applied to the hydrotherapy massage bed, and each nozzle can be controlled to rotate separately. The water column of the nozzle is sprayed onto the waterproof jacket and then transmitted to the human body to achieve the massage effect. Its effective area is no longer a fixed point but a surface. During the water column massage process, the massage effect can also be achieved by adjusting the inclination of the nozzle. At the same time, the flow rate of water out of the nozzle and the rotation of the nozzle are controlled by the ball valve to realize massage functions such as pushing, holding, rubbing, kneading, pinching, rubbing, pressing, massaging, patting, shaking, pulling, rolling and pulling; the water jet intensity and running route can be controlled in combination with the control of water flow temperature to imitate the pushing, holding, pinching, kneading and other movements of the human hand. The user can enjoy the massage effects of controllable temperature and frequency while sitting or lying down, and can program different massage methods.
