Description

Technical Field

[0001] The present invention relates to the technical field of airbag mattress inflation, in particular to an airbag mattress inflation and deflation assembly for adjusting the softness and hardness of a mattress by partition. Background Art

[0002] Application No. CN202420212313.2 discloses a zoned airbag mattress with adjustable comfort, the device including an elastic frame, which is used to wrap and fix components inside the mattress; an air blower, which is used to supply air when inflating the air mattress; the zoned airbag mattress also includes: an inflation device, which is used to inflate the airbags inside the airbag mattress; the inflation device includes a conveying pipe, the inner surface of the conveying pipe is rotatably connected to an adjustment device, the outer surface of the adjustment device is rotatably connected to an inflatable airbag, the end of the inflatable airbag away from the adjustment device is fixedly connected to an air outlet nozzle, the outer surface of the air outlet nozzle is threadedly connected to a sealing cover, a separation pad is provided on the outside of the sealing cover, and a vent is opened in the wall of the separation pad to pass through the separation pad and the adjustment device, thereby achieving the purpose of zoned adjustment of the comfort of the airbag mattress in different areas.

[0003] Due to the curvilinear structure of the human body, different areas of the airbag mattress will be concave when lying flat or on the side. This makes the user experience poor for rehabilitation patients or the elderly, and may even be counterproductive, causing fatigue damage to the affected parts of the body. Therefore, it is necessary to set up multi-zone adjustment scenarios based on the characteristics of different parts of the human body. Traditional solutions rely on multiple independent air pumps or complex air distributors, which have high hardware costs and uneven air pressure distribution, and are prone to local overcharging or underpressure. In addition, the lack of dynamic pressure self-adaptation requires users to frequently manually adjust parameters, which is especially poor for elderly people or rehabilitation patients with limited mobility. Summary of the Invention

[0004] In order to overcome the defects in the prior art, the purpose of the present invention is to provide an airbag mattress inflation and deflation assembly for adjusting the softness and hardness of the mattress by partition, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides an airbag mattress inflation and deflation assembly for zoned adjustment of softness and hardness, comprising a bladder mattress having a plurality of sealed interlayers between the long sides thereof, thereby dividing the interior of the bladder mattress into at least four independent airbag zones: a headrest zone, a waist and back zone, a hip pressure zone, and a leg rest zone; An air conditioning unit is provided on the long side of the bladder mattress, comprising a ventilation tube connected to the interior of the bladder mattress, an air pump controller connected to one end of the ventilation tube, and several electric air valves nested on the sides of the ventilation tube. Each of the four independent airbag areas is provided with an electric air valve. The air pump controller has a built-in control module and software system for controlling the opening and closing of the electric air valves individually or in pairs. Each of the four independent airbag areas is equipped with an air pressure sensor for real-time monitoring of the air pressure value in each area and feeding back to the control module. The software system includes a single-mode adjustment unit. When the user selects a single independent airbag zone, the corresponding electric valve is opened to perform independent inflation and deflation. The dual-mode adjustment unit allows the user to select any two independent airbag zones and simultaneously open the two corresponding electric valves to inflate and deflate the two zones independently.

[0006] As a further improvement of the present technical solution, flexible pressure sensing sheets are arranged at equal intervals on the inner layer of the top of the bladder mattress to monitor the pressure distribution ratio of the body on the bladder mattress in real time.

[0007] As a further improvement of the present technical solution, the software system of the air pump controller has a built-in dynamic pressure balance algorithm, which automatically controls the opening and closing timing of the two corresponding electric air valves according to the air pressure values ​​of the two independent airbag areas, and inflates according to the pressure distribution ratio to achieve a matching air pressure ratio.

[0008] As a further improvement of this technical solution, the software system of the air pump controller is provided with a human posture adaptive unit, which automatically matches the preset inflation mode according to the pressure distribution data: When a side-lying posture is detected, dual-mode inflation of the lumbar back area and the buttocks pressure area is activated; When a lying flat posture is detected, dual-mode inflation of the headrest area and the waist and back area is activated to conform to the lying posture of the human body curve.

[0009] As a further improvement of the present technical solution, air holes are provided on both long sides of the bag mattress and in the four independent air bag areas. One side of the ventilation tube is connected with a number of branch air tubes, and the branch air tubes are plugged and sealed correspondingly to the air holes on the same side. The other end of the ventilation tube is threadedly connected with a cap.

[0010] As a further improvement of the present technical solution, the electric air valve includes a pipe sleeve tightly fitted with the air distribution pipe, a pipe plug coaxially arranged at the air outlet end of the pipe sleeve, and an electromagnetic component coaxially arranged at the air inlet end of the pipe sleeve; the air outlet end of the pipe sleeve is provided with a funnel-shaped air nozzle, the pipe plug is made of a frustum of silica gel and is snap-fitted with the air nozzle, and an iron sleeve is coaxially inserted into one end of the pipe plug. When the electromagnetic component is energized, it generates magnetism and the magnetic iron sleeve drives the pipe plug and the air nozzle to separate, thereby communicating the airflow.

[0011] As a further improvement of the present technical solution, the electromagnetic component includes an electromagnetic column wound with a coil, a sleeve adapted to be fitted with the electromagnetic column, and a compression spring sleeved on the outside of the sleeve, one end of the compression spring rests on the boss on the outer wall of the sleeve, and the other end of the compression spring is fixedly connected to the port of the iron sleeve, and the iron sleeve is sleeved and slid on the outer wall of the sleeve.

[0012] As a further improvement of the present technical solution, protruding rods are provided on both sides of the closed end of the sleeve, and the inner wall of the large-aperture end of the sleeve is symmetrically provided with card grooves, and a pair of protruding rods are correspondingly engaged with a pair of card grooves.

[0013] As a further improvement of the present technical solution, the closed end of the shaft sleeve is in a tapered sleeve structure, and the large-aperture end of the pipe sleeve is provided with an inwardly facing chamfered surface.

[0014] As a further improvement of the present technical solution, a side band is bonded to the bottom of the long side of the bladder mattress, a magic tape is bonded to the top of the long side of the bladder mattress, the side band covers the ventilation tube and is bonded to the magic tape, and the two ends of the side band are sewn with a strap that is mounted on the air pump controller.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The airbag mattress inflation and deflation component, which is used to adjust the softness and hardness of different areas, divides the airbag mattress horizontally into several areas to match the support at the intersection of the human body curves. The single-mode and dual-mode design of the air pump controller allows patients to freely choose combinations such as the headrest area or the waist and back area + leg rest area to adjust the air pressure to support the required parts, breaking through the limitations of traditional fixed areas and meeting the precise support needs of lumbar rehabilitation patients and the elderly.

[0016] 2. The airbag mattress inflation and deflation component, which is used to adjust the softness and hardness of the mattress in different areas, uses flexible pressure sensors and adaptive algorithms to monitor the user's body pressure distribution in real time and automatically match the inflation mode. It automatically strengthens the support of the waist and hip area when lying on the side, and adjusts the air pressure of the head, neck and legs when lying flat, reducing the frequency of manual operation by the user.

[0017] 3. The airbag mattress inflation and deflation component for zoned hardness adjustment replaces the multi-air pump hardware solution through software algorithms, completing the independent control of multiple zones of the airbag mattress using a single air pump and several electric air valves, thereby reducing hardware costs.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. Furthermore, in the description of the present invention, "several" means two or more, unless otherwise specifically defined.

[0022] See also Figures 1-9 As shown, the present invention provides an airbag mattress inflation and deflation assembly for zoned adjustment of softness and hardness, comprising a bladder mattress 100 having a plurality of sealed interlayers between its internal long sides, thereby dividing the interior of the bladder mattress 100 into at least four independent airbag zones: a headrest zone 101, a waist and back zone 102, a hip pressure zone 103, and a leg rest zone 104; so that the air pressure of different parts of the human body corresponding to these four independent airbag zones can be adjusted separately when lying down.

[0023] Furthermore, the mattress 100 further includes an air regulating unit 200 disposed on the long side of the bladder mattress 100. The air regulating unit 200 includes a ventilation tube 210 connected to the interior of the bladder mattress 100, an air pump controller 220 connected to one end of the ventilation tube 210, and a plurality of electric air valves 230 nested on the side of the ventilation tube 210. A side band 110 is bonded to the bottom of the long side of the bladder mattress 100, and a magic tape 112 is bonded to the top of the long side of the bladder mattress 100. The side band 110 covers the ventilation tube 210 and is bonded to the magic tape 112. Both ends of the side band 110 are sewn with a sleeve 111 that is sleeved with the air pump controller 220, so that the ventilation tube 210 and the air pump controller 220 are stabilized on the side of the bladder mattress 100, and the air pump controller 220 can adjust the position of the air pump controller 220 according to the power sockets at the four corners of the mattress, which has the characteristics of humanized design.

[0024] Furthermore, an electric valve 230 is arranged in each of the four independent airbag areas. The air pump controller 220 has a built-in control module and software system for controlling the opening and closing of several electric valves 230 individually or in pairs. The four independent airbag areas are each equipped with an air pressure sensor for real-time monitoring of the air pressure value in each area and feeding it back to the control module.

[0025] Among them, the software system includes a single-mode adjustment unit. When the user selects a single independent airbag area, the corresponding electric valve 230 is opened for independent inflation and deflation; a dual-mode adjustment unit. When the user selects any two independent airbag areas, the two corresponding electric valves 230 are opened synchronously to independently inflate and deflate the two areas.

[0026] Furthermore, flexible pressure sensing sheets are arranged at equal intervals on the inner layer of the top of the bladder mattress 100 to monitor in real time the pressure distribution ratio of the body on the bladder mattress 100; the software system of the air pump controller 220 has a built-in dynamic pressure balance algorithm, which automatically controls the opening and closing timing of the corresponding two electric air valves 230 according to the air pressure values ​​of the two independent air bag areas, and inflates the air to achieve a matching air pressure ratio according to the pressure distribution ratio.

[0027] The inflation time is dynamically adjusted by calculating the pressure value ratio of different positions of the bladder mattress 100 in real time, and the areas with large deviations are processed first. For example, when the waist and back area 102 is under-pressured, the electric air valve 230 there is opened first for inflation.

[0028] Specifically, the software system architecture code of the air pump controller 220 of the present invention is: class AirMattressController: def __init__(self): # Hardware initialization self.valves = { # Solenoid valve control object (example) 'head': Valve(pin=12), 'lumbar': Valve(pin=13), 'hip': Valve(pin=14), 'leg': Valve(pin=15)} self.pump = Pump(pin=16) # Pump control self.sensors = { # Pressure sensor zone: PressureSensor() for zone in ['head', 'lumbar', 'hip', 'leg']} # Control parameters self.mode = 'single' # Current mode (single / dual) self.target_pressures = {} # Target pressure for each area self.pid_controllers = {} # PID controller instance def run(self): while True: self.read_sensors() self.adjust_pressure() time.sleep(0.1) # 100ms control period.

[0029] Specifically, the dynamic pressure balance algorithm of the present invention is: a. Pressure control core code class PIDController: def __init__(self, Kp=1.2, Ki=0.05, Kd=0.1): self.Kp, self.Ki, self.Kd = Kp, Ki, Kd self.integral = 0 self.prev_error = 0 def compute(self, current, target): error = target - current self.integral += error derivative = error - self.prev_error output = self.Kp*error + self.Ki*self.integral + self.Kd*derivative self.prev_error = error return max(0, min(output, 1)) # Output is limited to 0~1 (air pump power percentage); b. Dynamic balance inflation logic def adjust_pressure(self): if self.mode == 'dual': zones = self.selected_zones # Two zones selected by the user (such as ['lumbar', 'leg']) pressures = {z: self.sensors[z].read() for z in zones} # Calculation priority: The area with a larger difference between the target pressure and the current pressure is inflated first priority = sorted(zones, key=lambda z: abs(self.target_pressures[z] - pressures[z]), reverse=True ) # Dynamically allocate inflation time slices (unit: ms) for zone in priority: pid = self.pid_controllers[zone] pump_power = pid.compute(pressures[zone], self.target_pressures[zone]) # Open the valve in the current area and inflate self.valves[zone].open() self.pump.set_power(pump_power) time.sleep(10 * pump_power) # Inflation time is proportional to power # Close the valve and pause (to prevent airflow crosstalk) self.valves[zone].close() self.pump.set_power(0) time.sleep(5). Furthermore, the software system of the air pump controller 220 is provided with a human posture adaptive unit, which automatically matches the preset inflation mode according to the pressure distribution data: When a side-lying posture is detected, dual-mode inflation of the waist and back area 102 and the buttocks pressure area 103 is activated; When a lying posture is detected, dual-mode inflation of the headrest area 101 and the waist and back area 102 is activated to conform to the lying posture of the human body curve.

[0030] Specifically, the code for adaptive mode switching based on pressure sensor data is as follows: def detect_posture(self): # Determine pressure distribution characteristics (example: waist-hip pressure difference > threshold when lying on the side) lumpar_p = self.sensors['lumbar'].read() hip_p = self.sensors['hip'].read() if abs(lumbar_p - hip_p)>15: # Unit kPa self.switch_to_dual_mode(['lumbar', 'hip'], ratio=1.2) else: self.switch_to_dual_mode(['head', 'leg']). Further, pressure balance test script: # Simulate dual zones (back zone target 30kPa, leg target 20kPa) controller = AirMattressController() controller.mode = 'dual' controller.target_pressures = {'lumbar': 30, 'leg': 20} # Record inflation process data pressures = {'lumbar': [], 'leg': []} for _ in range(100): # simulate 10 seconds of inflation controller.run_cycle() pressures['lumbar'].append(controller.sensors['lumbar'].read()) pressures['leg'].append(controller.sensors['leg'].read()) # Generate pressure curve (expected two zones to reach the target simultaneously) import matplotlib.pyplot as plt plt.plot(pressures['lumbar'], label='Lumbar') plt.plot(pressures['leg'], label='Leg') plt.show(). Furthermore, add pressure mutation protection code: if current_pressure - target>5: # Emergency exhaust when overpressure self.valves[zone].open() self.pump.set_power(-0.5) # Assume that reverse pumping is supported.

[0031] like Figure 5-Figure 7 As shown, further, air holes 105 are provided on both long sides of the bag mattress 100 and in the four independent air bag areas. A plurality of branch air pipes 211 are connected to one side of the ventilation tube 210. The plurality of branch air pipes 211 are correspondingly plugged and sealed with the plurality of air holes 105 on the same side. A cap is threadedly connected to the other end of the ventilation tube 210 so that when the air pump controller 220 at the other end of the ventilation tube 210 is inflated or deflated, only one channel is left in the ventilation tube 210 for inflation or deflation.

[0032] Specifically, the electric air valve 230 includes a pipe sleeve 231 tightly fitted with the air distribution pipe 211, a pipe plug 232 coaxially arranged at the air outlet end of the pipe sleeve 231, and an electromagnetic component 233 coaxially arranged at the air inlet end of the pipe sleeve 231; the air outlet end of the pipe sleeve 231 is provided with a funnel-shaped air nozzle 2311, the pipe plug 232 is made of a frustum of silica gel and is snap-fitted with the air nozzle 2311, and an iron sleeve 2321 is coaxially inserted into one end of the pipe plug 232. When the electromagnetic component 233 is energized, it is magnetized and the magnetic iron sleeve 2321 drives the pipe plug 232 to separate from the air nozzle 2311, thereby communicating the airflow.

[0033] Furthermore, the electromagnetic component 233 includes an electromagnetic column 2331 wound with a coil, a sleeve 2332 adapted to be matched with the electromagnetic column 2331, and a compression spring 2333 sleeved on the outside of the sleeve 2332. The coil on the outside of the electromagnetic column 2331 is connected to the power supply area of ​​the control module circuit board of the air pump controller 220, so as to obtain electricity for operation; one end of the compression spring 2333 is against the boss on the outer wall of the sleeve 2332, and the other end of the compression spring 2333 is fixedly connected to the port of the iron sleeve 2321, and the iron sleeve 2321 is sleeved and slidably with the outer wall of the sleeve 2332; when the pipe plug 232 is closed, the compression spring 2333 is in a state of pressing the pipe plug 232; when the electromagnetic column 2331 magnetically attracts the pipe plug 232 from the air nozzle 2311, the compression spring 2333 is in a contracted state, waiting to reset the pressing pipe plug 232 to seal the pipe sleeve 231.

[0034] Furthermore, protruding rods are provided on both sides of the closed end of the sleeve 2332, and the inner wall of the large-aperture end of the pipe sleeve 231 is symmetrically provided with card grooves 2312. A pair of protruding rods and a pair of card grooves 2312 are correspondingly engaged with each other, so that the sleeve 2332 can be stably installed; the closed end of the sleeve 2332 is a conical sleeve structure, and the large-aperture end of the pipe sleeve 231 is provided with an inward-facing chamfered surface, so that the airflow entering the pipe sleeve 231 from the ventilation pipe 210 can flow quickly along the two inclined surfaces.

[0035] like Figure 8 and Figure 9As shown, the airbag mattress inflation and deflation component for adjusting the softness and hardness by zone of the present invention uses a single-mode adjustment function when in use. The user uses a single target area, such as the headrest area, on the touch screen of the air pump controller 220. The software sends an opening instruction to the electric air valve 230 corresponding to the area, and the electromagnetic column 2331 connects the electromagnetic straw plug 232 to disengage the air nozzle 2311. At the same time, the air pump controller 220 is started, and the air volume is automatically controlled by the real-time feedback of the air pressure value by the air pressure sensor. The user can manually increase or decrease the air pressure to the target value; and a "one-click matching" button for the optimal softness and hardness is provided, which automatically inflates to the recommended value according to the preset ergonomic data, such as low pressure in the headrest area and high support in the waist and back area.

[0036] Using the dual-mode adjustment function, the user selects any two areas, such as the waist and back area + the leg rest area. The software synchronously controls the opening of the electric air valves 230 in the two areas. The air pump controller 220 uses the dynamic pressure balance algorithm of the software to open the electric air valves 230 in the two areas in turn, realizing independent air pressure adaptive human body adjustment in the two areas, which is suitable for use in lumbar rehabilitation scenarios.

[0037] It should be noted that the above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
