Description

[Technical Field]

[0001] The present invention relates to a portable wireless powered inflation device, and more particularly to an apparatus and method for inflating or deflating an air mattress using a portable wireless powered inflation device, or for integrally connecting a portable wireless powered inflation device to an air mattress to inflate or deflate the air mattress, or for maintaining the air inflated in the air mattress at a constant pressure. [Background technology]

[0002] Generally, an air pump draws in external air, compresses it, and then injects it into an inflatable object such as an air tent or an air mattress. Such air pumps are divided into manual types that are operated by manual pumping and electric types that are operated by electric pumping.

[0003] Conventionally, when using a manual air pump to inflate air into an air mattress or air tent that maintains a predetermined shape by inflating it, the user must manually operate the manual air pump to pump a large amount of air, which requires considerable effort. Furthermore, the air pressure in the air mattress or air tent cannot be accurately determined, resulting in problems such as different air pressures each time the pump is used. In contrast, electric pumps are simple because they use electricity to pump air, but they also have problems such as being unable to determine the air pressure or maintaining a constant air pressure. Furthermore, air mattresses and air tents become hard or soft due to thermal expansion or contraction of the air injected into them as the ambient temperature changes, making it difficult to maintain a constant air pressure.

[0004] As a prior art, Patent Document 1 discloses a system that injects air at a certain pressure into an air mattress and maintains the cushion strength of the air mattress at a set strength. However, there are problems with this system, such as being unable to respond to temperature changes in the air mattress, being unable to check the current operating status of the air mattress, and being unable to fine-tune the air pressure.

DETAILED DESCRIPTION OF THE INVENTION

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable wireless electric air inflator according to the present invention will now be described in detail with reference to the accompanying drawings.

[0021] 1 and 2 show a portable wireless electric inflation device according to the present invention, which is used to inflate objects such as air tents, air mattresses, air sofas, air bounces, tubes installed in bicycles and motorcycles, and automobile tires. The portable wireless electric inflation device 1 comprises a housing 2 having a space therein for accommodating various components, and a control panel 13 equipped with a plurality of selection buttons and a display unit 33 on the front side of the housing 2. A handle 4 is hingedly attached to the front side of the housing 2 so that the device can be held and carried by hand. A strap or the like can be attached to the handle 4 so that the device can be worn on the shoulder.

[0022] The lid 3 is attached to the housing 2 so that the top surface of the housing 2 can be opened, and the inside can be opened and closed for maintenance of the portable wireless electric air inflator 1.

[0023] An air inlet 20 and an air inlet 21 protrude from the rear surface of the housing 2. Threads are formed on the surfaces of the ends of the air inlet 20 and the air inlet 21, allowing hoses for injecting or suctioning air to be connected. The air inlet 20 discharges compressed air from within the air injection device 1 so that air can be injected into the object to be inflated, and the air inlet 21 draws in air filled in the object to be inflated and discharges it to the outside.

[0024] A plurality of exhaust holes are formed on the underside of the housing 2 so that heat generated from the internal components can be discharged to the outside by compressing, injecting, and suctioning air, and a plurality of anti-slip mats, tapes, stickers, etc. are attached to the underside of the housing 2.

[0025] 3 is a block diagram showing the configuration of a portable wireless electric air injection device. Low-pressure, high-flow pump 15 injects a fixed amount of air into object 50 to be inflated up to a first set pressure and compresses and discharges a large amount of air at a low pressure. The low-pressure, high-flow pump 15 can be a pump that can pump air up to a first set pressure of approximately 2 psi. A BLDC pump can be used as the low-pressure, high-flow pump 15. In addition, a first check valve 16 is installed in low-pressure, high-flow pump 15 to prevent the backflow of air injected from high-pressure, low-flow pump 17 along with the air injected into object 50.

[0026] The high-pressure, low-flow pump 17 injects a fixed amount of air up to a second set pressure after the low-pressure, high-flow pump 15 has injected air up to a first set pressure. The high-pressure, low-flow pump 17 compresses a small amount of air at high pressure and gradually injects or discharges it. The high-pressure, low-flow pump 17 may be equipped with a pump that can pump air up to a second set pressure of approximately 12 psi. The low-pressure, high-flow pump 15 injects approximately 90% of the air into the object 50, and the high-pressure, low-flow pump 17 pumps and injects the remaining approximately 10% of the air into the object 50. The high-pressure, low-flow pump 17 is equipped with a second check valve 19, which prevents the air injected into the object 50 from being reversed by the low-pressure, high-flow pump 15.

[0027] In addition, an electromagnetic valve 18 is installed between the high-pressure, low-flow pump 17 and the second check valve 19, and can be opened and closed under the control of the controller 10 when the high-pressure, low-flow pump 17 is operating.

[0028] The pressure sensor 11 detects the air pressure of the inflatable object 50. The pressure sensor 11 detects the pressure of the air filled in the inflatable object 50 in real time and transmits the detected value to the controller 10. The temperature sensor 12 detects the temperature of the air inside the inflatable object 50. The temperature sensor 12 detects changes in the internal temperature of the inflatable object 50 depending on the ambient temperature of the location where the inflatable object 50 is installed. Even if air is initially injected into the inflatable object 50 at a set pressure, changes in the internal temperature of the inflatable object 50 occur depending on the time of day or night or changes in weather, and the temperature sensor 12 is able to detect such temperature changes. That is, when the temperature rises due to changes in the ambient temperature of the inflatable object 50, the pressure increases, and when the temperature drops, the pressure decreases. Therefore, even if air is initially injected into the inflatable object 50 at a set pressure, the inflatable object 50 expands or contracts depending on the temperature change. Therefore, when the temperature sensor 12 detects a change in the internal temperature of the object 50 to be inflated and transmits the detected value to the controller 10, the controller 10 operates the high-pressure, low-flow pump 17 to inject or expel air into or from the object 50 to be inflated, thereby maintaining a constant pressure.

[0029] As shown in FIG. 4, the control panel 13 allows the user to select or set the corresponding function for injecting or expelling air into the inflatable object 50, and displays the operating state and current status of the air injection device 1. The power button 30 provided on the control panel 13 operates or stops the air injection device 1 by applying or cutting off power from the power supply unit 23. The air injection start / stop button 31 selects the function of injecting air into the inflatable object 50 or cutting off air injection. After selecting the air injection start / stop button 31 to operate the air injection device 1, the air injection device 1 can be stopped by selecting the air injection start / stop button 31 while it is operating.

[0030] The pressure adjustment button 32 is used to select whether to increase or decrease the pressure of the air injected into the inflatable object 50 in set steps. That is, after connecting the inflatable object 50 to the air injection device 1, the pressure adjustment button 32 is used to set the injection air pressure, and the air injection device 1 injects air up to the set pressure. After air has been injected into the inflatable object 50 up to the set pressure, the user can determine whether to inject more air into the inflatable object 50 or to suck air by selecting the pressure adjustment button 32.

[0031] As shown in FIG. 5, the display unit 33 visually displays the operating status and current status of the air inflation device 1 while it is inflating or discharging air. The display unit 33 may be an OLED display device with excellent readability and visibility. For example, the display unit 33 of FIG. 5a displays the air tent mode set as the inflation object 50 and indicates a stop state. The display unit 33 of FIG. 5b displays the air mattress mode set as the inflation object 50 and indicates an operating state (Run3). The display unit 33 also displays a memory function that can store three desired pressure values, indicates the remaining battery charge of the power supply 23, displays the real-time pressure value (0.0 PSI) and the set pressure value (SET5.00), and indicates the charge status of the power supply 23 battery.

[0032] The first to third memory buttons 34 to 36 are used to store the pressure values ​​set by the user or to operate the air injection device 1 at the stored set pressure values. The controller 10 stores the input and set pressure values ​​of the first to third memory buttons 34 to 36 and then controls the device to inject air at the corresponding set pressure selected by the user.

[0033] Charging jack 37 is used to connect a power plug for charging multiple batteries built into power supply unit 23. The charger connected to charging jack 37 can be one that converts input AC power (100 to 220 VAC / 60 Hz) into DC power (12 VDC / 2 A) and outputs it.

[0034] The alarm means 14 also emits a warning sound or voice to notify various operating conditions while injecting or expelling air into the inflatable object 50. That is, the alarm means 14 outputs a voice or a warning sound to guide the user regarding input, selection, and setting, or outputs a voice or a warning sound to audibly notify the current conditions, such as the general operation of the air injection device 1 operated under the control of the controller 10, overheating during operation, and air leakage.

[0035] The controller 10 controls the operation of the low-pressure, high-flow pump 15 and the high-pressure, low-flow pump 17 according to the values ​​sensed by the pressure sensor 11 and the temperature sensor 12, controls the opening and closing of the electromagnetic valve 18, controls the selection, setting and display of the control panel 13, and outputs various alarm sounds or audio signals via the alarm means 14. The controller 10 also inputs and outputs control signals for saving and controlling the input, selection and setting via a plurality of memory buttons 34 to 36.

[0036] The power supply unit 23 supplies the power necessary for the operation of the relevant components related to injecting or expelling air into the object to be inflated 50, and has multiple batteries built in, converting the battery power into the power necessary for the operation of the air injection device 1 and supplying it.

[0037] The operation of the portable wireless electric air inflator according to the present invention constructed as above will now be described.

[0038] 6 is a flowchart showing a method for inflating air using a portable wireless electric air inflation device. First, the portable wireless electric air inflation device 1 is connected to the object to be inflated 50 (S1). That is, hoses for injecting and discharging air are connected to the air inlet 20 and air intake 21 of the air inflation device 1 and the corresponding air inlet 20 and air intake 21 of the object to be inflated 50, respectively. Here, depending on the object to be inflated 50, it may not be necessary to connect a separate hose to the air intake 21.

[0039] Once the hose connection is complete, the power button 30 on the control panel 13 is pressed to operate the air injection device 1 (S2). Then, the pressure adjustment button 32 is pressed to select whether to increase or decrease the pressure (S3). The pressure adjustment button 32 can be selected in stages, for example, 0 to 12 stages or 0 to 12 psi. The increase or decrease selection of the pressure adjustment button 32 can vary depending on the size and type of the object 50 to be inflated.

[0040] Then, the air injection start / stop button 31 configured on the control panel 13 is selected to operate the air injection device 1 (S4). When the air injection start / stop button 31 is selected to operate the air injection device 1, the controller 10 operates the low-pressure, high-flow pump 15 (S5). Low-pressure air compressed by the low-pressure, high-flow pump 15 passes through the first check valve 16 and is injected into the object to be inflated 50 via the air inlet 20, filling it. Here, the low-pressure, high-flow pump 15 compresses and discharges a large amount of air at low pressure. This is because the object to be inflated 50 initially has almost no air pressure, so low-pressure air is injected.

[0041] The controller 10 injects low-pressure air into the inflatable object 50 through the operation of the low-pressure, high-flow pump 15, and determines whether the pressure value sensed by the pressure sensor 11 reaches the first set pressure (S6). The first set pressure may vary depending on the type and size of the inflatable object 50. The first set pressure may be up to approximately 90% of the total set air pressure. For example, air is inflated to 1.8 psi for an air mattress and 9.8 psi for an air tent.

[0042] Furthermore, when the pressure value continuously sensed by pressure sensor 11 while low-pressure, high-flow pump 15 is operating reaches the first set pressure, controller 10 stops the operation of low-pressure, high-flow pump 15 and operates high-pressure, low-flow pump 17 (S7). Then, controller 10 switches solenoid valve 18 to gradually inject small amounts of high-pressure air compressed by low-noise operating high-pressure, low-flow pump 17 through second check valve 19 and air inlet 20 into object 50 to be inflated, gradually filling it with high-pressure air.

[0043] As the controller 10 injects high-pressure air into the inflatable object 50 through the operation of the high-pressure, low-flow pump 17, it determines whether the pressure value sensed by the pressure sensor 11 reaches the second set pressure (S8). The second set pressure may vary depending on the type and size of the inflatable object 50. The second set pressure is the remainder of the total set air pressure and may be up to approximately 10%. For example, air is inflated to 2.0 psi for an air mattress and 12 psi for an air tent.

[0044] Next, when the pressure value continuously sensed by pressure sensor 11 while high-pressure, low-flow pump 17 is operating reaches the second set pressure, controller 10 stops the operation of high-pressure, low-flow pump 17 and switches to a monitoring mode in which a change in pressure value is sensed (S9). Here, operation of high-pressure, low-flow pump 17 is stopped, and solenoid valve 18 is switched off in response to a control signal from controller 10. In the monitoring mode, the pressure of object 50 to be inflated is sensed at regular intervals, for example, every 20 minutes, and if the air pressure is lower than the second set pressure, high-pressure, low-flow pump 17 is operated to inflate object 50. Then, at the user's discretion, after inflating object 50 to the set pressure, the user can further inject air or evacuate the injected air by adjusting the air pressure using pressure adjustment button 32. Therefore, the controller 10 senses input from the pressure adjustment button 32, and when an increase in pressure (▲) is input, it operates the high-pressure, low-flow pump 17 to inject more air into the object to be inflated 50 up to the set pressure, and when a decrease in pressure (▼) is input, it switches the third check valve 22 to discharge the air filled in the object to be inflated 50 (S10).

[0045] Thereafter, when the pressure reaches the pressure set by the pressure adjusting button 32, the controller 10 switches to a monitoring mode and continuously monitors the internal pressure and temperature of the object 50 to be inflated by the pressure sensor 11 and the temperature sensor 12 (S11). Therefore, when the internal pressure and temperature of the object 50 to be inflated are outside the set pressure and temperature ranges, the controller 10 repeatedly executes steps S7 to S9.

[0046] Next, after the air inflation device 1 is operated by selecting the power button 30 in step S2, the user can select any one of the first to third memory buttons 34 to 36 on the control panel 13 in which the set pressure is stored, without selecting the pressure adjustment button 32 (S20). Therefore, the controller 10 executes steps S4 to S11 at the pressure value set in any one of the first to third memory buttons 34 to 36 according to the user's selection.

[0047] FIG. 7 is a flowchart showing a method for setting the air pressure using the first through third memory buttons 34-36. After operating the air inflation device 1 by selecting the power button 30 on the control panel 13, the user selects one of the memory buttons 34-36 to save multiple set pressure values ​​(S21). When the user selects one of the memory buttons 34-36, the controller 10 displays the selected memory number on the display 33. When the user sets the pressure value by increasing or decreasing it using the pressure adjustment button 32, the controller 10 displays the pressure value on the display 33 (S22). After the pressure value is set, the controller 10 saves the set pressure value by pressing the selected one of the first through third memory buttons 34-36 for a certain period of time (S23). A message indicating that the set pressure value has been saved to the corresponding first through third memory button 34-36 is displayed on the display 33, completing the saving process.

[0048] Thereafter, when the user presses the corresponding memory button 34-36 in which the set pressure value is stored among the first to third memory buttons 34-36 (S24) and then presses the air injection start / stop button 31, air is automatically injected at the set pressure value through the corresponding memory button 34-36 (S25). Therefore, the controller 10 executes steps S4 to S11 at the pressure value set in one of the first to third memory buttons 34-36 according to the user's selection.

[0049] 8 is a diagram showing another embodiment of the present invention, in which the control panel 13 may further include an inflatable object selection button 38. The inflatable object 50 may be an object that continuously maintains a set pressure, such as an air tent, an air mattress, an air sofa, or an air bouncer for babies, or may be a disposable inflatable object, such as an inner tube in a motorcycle wheel, an inner tube in a bicycle wheel, or a vehicle tire. Therefore, by selecting the inflatable object selection button 38, the controller 10 can automatically inflate the corresponding object for inflation at a set pressure value or a pressure value selected by the user.

[0050] In addition, the control panel 13 of the present invention may further include a voltage output jack 39 for lighting the LED lights using the battery of the power supply unit 23 built into the air injection device 1 or for charging a smartphone.

[0051] The present invention may also include a smoke screen device that sprays a smoke agent capable of displaying a predetermined color, which is installed in parallel on one side of the air inlet 20 of the high-pressure, low-flow pump 17. The smoke screen device is installed on one side of the air inlet 20, and when the user selects the smoke screen button 40, the smoke agent having the color is discharged at the portion where air leaks from the inflatable object 50 in response to a control signal from the controller 10, making it easy to locate the air leak. Therefore, the smoke screen device continuously monitors the internal pressure of the inflatable object 50 for a certain period of time using the pressure sensor 11, and when the internal pressure of the inflatable object 50 deviates significantly from the set pressure, it can be determined that a portion of the inflatable object 50 has been ruptured or a gap has developed.

[0052] Next, an embodiment of the portable wireless powered inflation device of the present invention integrally coupled within an air mattress will be described.

[0053] Figure 9 is a perspective view of the air mattress with an integrated wireless electric air inflation device of the present invention, and Figure 10 is a side view thereof. An air inflation device 1 is integrally connected to the air mattress 100 as an object to be inflated. The air inflation device 1 is used to inflate and deflate air into the air mattress 100.

[0054] The air mattress 100 allows one or more users to lie or sit on its surface and can be used for camping, travel, bedrooms, hospital patient beds, etc. The air mattress 100 is formed to have a certain volume that is filled with air at a certain pressure.

[0055] As shown in Figure 11, the air inflation device 1 can be inserted into and connected to the side of the air mattress 100. That is, as shown in Figure 12, a connection hole 102 is formed in the air mattress 100, and the connection device 110 can be fixedly connected to the air mattress 100. The case 111 of the connection device 110 is inserted into the connection hole 102 formed in the side of the air mattress 100, and a flange 112 is formed on the edge of the entrance that is open at the front. The air inflation device 1 is inserted into the case 111 and fixed therein.

[0056] Cover 116 also covers and shields the front of case 111 when air injection device 1 is not in use. Cover 116 is hinged via hinge member 118 connected to one side of flange 112. The other side of cover 116 can be locked or unlocked by locking member 119 connected to the other side of flange 112. Cover 116 is formed with a transparent window 117 so that the operating state and current status of air injection device 1 can be checked via a display unit provided on the control panel of air injection device 1.

[0057] In addition, a recognition protrusion 113 of a certain length is protruded from the inside of the case 111. The recognition protrusion 113 enables determination that the air inflation device 1 has been inserted into and coupled to the air mattress 100, and is inserted into an air mattress detection sensor 24 formed on the rear of the air inflation device 1. In addition, an air inflation port insertion port 114 is provided on the inside of the case 111 to receive and couple with the air inflation port 20 protruding from the rear of the air inflation device 1, and an air inlet insertion port 115 is provided on the inside of the case 111 to receive and couple with the air inlet 21 protruding from the rear of the air inflation device 1. It is preferable to have a coupling structure that can maintain airtightness by coupling the air inflation port 20 of the air inflation device 1 with the air inflation port insertion port 114 and the air inlet 21 of the air inflation device 1 with the air inlet insertion port 115.

[0058] 13 is a block diagram showing the configuration of a portable wireless electric air inflation device that can be connected to an air mattress 100. A low-pressure, high-flow pump 15 injects a certain amount of air into the air mattress 100 up to a first set pressure and compresses and discharges a large amount of air at a low pressure. The first set pressure of the low-pressure, high-flow pump 15 can be a pump that can pump air up to a maximum pressure of approximately 2 psi. A BLDC pump can be used as the low-pressure, high-flow pump 15. A first check valve 16 is also installed in the low-pressure, high-flow pump 15 to prevent the air injected into the air mattress 100 from flowing back from the high-pressure, low-flow pump 17.

[0059] The high-pressure, low-flow pump 17 injects a fixed amount of air up to a second set pressure after the low-pressure, high-flow pump 15 has injected air up to a first set pressure. The high-pressure, low-flow pump 17 compresses a small amount of air at high pressure and gradually injects or expels it. The second set pressure of the high-pressure, low-flow pump 17 can be a pump that can pump air up to a maximum pressure of approximately 12 psi. The low-pressure, high-flow pump 15 injects approximately 90% of the air into the air mattress 100, and the high-pressure, low-flow pump 17 pumps the remaining approximately 10% of the air into the air mattress 100. The high-pressure, low-flow pump 17 is also equipped with a second check valve 19 to prevent the air injected from the low-pressure, high-flow pump 15 from flowing back in with the air injected into the air mattress 100.

[0060] Furthermore, an electromagnetic valve 18 is installed between the high-pressure, low-flow pump 17 and the second check valve 19, so that it can be opened and closed under the control of the controller 10 when the high-pressure, low-flow pump 17 is in operation.

[0061] The pressure sensor 11 detects the air pressure of the air mattress 100. The pressure sensor 11 detects the pressure of the air filled in the air mattress 100 in real time and transmits the detected value to the controller 10. The temperature sensor 12 detects the temperature of the air inside the air mattress 100. The temperature sensor 12 detects changes in the internal temperature of the air mattress 100 depending on the ambient temperature of the place where the air mattress 100 is installed or the body temperature of the user using the air mattress 100. Even if air is initially inflated into the air mattress 100 at a set pressure, the internal temperature of the air mattress 100 may change depending on the time of day, night, or weather, and the temperature sensor 12 detects such temperature changes. That is, when the ambient temperature of the air mattress 100 changes, the pressure increases and when the temperature decreases, the pressure decreases. Therefore, even if air is initially inflated into the air mattress 100 at a set pressure, the air mattress 100 will expand or contract depending on the temperature change. Therefore, when the temperature sensor 12 detects a change in the internal temperature of the air mattress 100 and transmits the detected value to the controller 10, the controller 10 operates the high-pressure, low-flow pump 17 to inject or evacuate air into or from the air mattress 100, thereby maintaining a constant pressure.

[0062] The air mattress detection sensor 24 detects whether the recognition protrusion 113 of the coupling device 110 is inserted, detects the coupling state with the air mattress 100, and transmits the detected value to the controller 10. Therefore, the controller 10 can control various operations specifically for the air mattress depending on whether the air mattress 100 is coupled.

[0063] The portable wireless electric air inflator 1 integrally combined with the air mattress 100 according to the present invention has the structure, functions and actions shown in FIGS.

[0064] The operation of the portable wireless electric air inflator-integrated air mattress according to the present invention configured as above will now be described.

[0065] 14 is a flowchart showing a method for controlling a wireless electric inflation device integrally coupled to an air mattress 100. First, the cover 116 covering the inflation device 1 on the side of the air mattress 100 is opened (S31). Here, the cover 116 is opened around the hinge member 118 after the locking member 119 is released. Then, the power button 30 configured on the control panel 13 is pressed to operate the inflation device 1 (S32). Then, the pressure adjustment button 32 is used to select whether to increase or decrease the pressure (S33). The pressure adjustment button 32 can be selected in stages, for example, 0 to 12 stages or 0 to 12 psi. The increase or decrease selection of the pressure adjustment button 32 may vary depending on the size and type of the air mattress 100.

[0066] Then, the air inflation start / stop button 31 configured on the control panel 13 is selected to operate the air inflation device 1 (S34). When the air inflation start / stop button 31 is selected to operate the air inflation device 1, the controller 10 operates the low-pressure, high-flow pump 15 (S35). Low-pressure air compressed by the low-pressure, high-flow pump 15 passes through the first check valve 16 and is injected into the air mattress 100 via the air inlet 20 to fill it. Here, the low-pressure, high-flow pump 15 compresses and discharges a large amount of air at low pressure. This is because the air mattress 100 initially has almost no air pressure, so low-pressure air is injected.

[0067] As the controller 10 injects pressurized air into the air mattress 100 through the operation of the low-pressure, high-flow pump 15, it determines whether the pressure value detected by the pressure sensor 11 has reached the first set pressure (S36). The first set pressure may vary depending on the type and size of the air mattress 100. The first set pressure may be up to approximately 90% of the total set air pressure. For example, in the case of an air mattress, air is injected until it reaches 1.8 psi.

[0068] Furthermore, when the pressure value continuously sensed by the pressure sensor 11 while the low-pressure, high-flow pump 15 is operating reaches the first set pressure, the controller 10 stops the operation of the low-pressure, high-flow pump 15 and operates the high-pressure, low-flow pump 17 (S37).The controller 10 then switches the solenoid valve 18 to gradually inject small amounts of high-pressure air compressed by the low-noise operating high-pressure, low-flow pump 17 into the air mattress 100 through the second check valve 19 and the air inlet 20, gradually filling the interior of the air mattress 100.

[0069] As the controller 10 injects high-pressure air into the air mattress 100 through the operation of the high-pressure, low-flow pump 17, it determines whether the pressure value sensed by the pressure sensor 11 reaches the second set pressure (S38). The second set pressure may vary depending on the type and size of the air mattress 100. The second set pressure is the remainder of the total set air pressure and may be up to approximately 10%. For example, in the case of an air mattress, air is injected until it reaches 2.0 psi.

[0070] Next, when the pressure value continuously sensed by the pressure sensor 11 while the high-pressure, low-flow pump 17 is operating reaches the second set pressure, the controller 10 stops the operation of the high-pressure, low-flow pump 17 and switches to a monitoring mode in which a change in the pressure value is sensed (S39). Here, the operation of the high-pressure, low-flow pump 17 is stopped, and the solenoid valve 18 is switched off in response to a control signal from the controller 10. In the monitoring mode, the pressure of the air mattress 100 is sensed at regular intervals, for example, every 20 minutes, and if the air pressure is lower than the second set pressure, the high-pressure, low-flow pump 17 is operated to inflate the air. Then, at the user's discretion, after the air mattress 100 has been inflated to the set pressure, the user can adjust the air pressure using the pressure adjustment button 32 to inflate the air or to evacuate the inflated air. Therefore, the controller 10 senses input from the pressure adjustment button 32, and when an increase in pressure (▲) is input, it operates the high-pressure, low-flow pump 17 to further inflate air into the air mattress 100 up to the set pressure, and when a decrease in pressure (▼) is input, it switches the third check valve 22 to discharge the air filled in the air mattress 100 (S40).

[0071] Thereafter, when the pressure reaches the pressure set by the pressure adjusting button 32, the controller 10 switches to the monitoring mode and continuously monitors the internal pressure and temperature of the air mattress 100 using the pressure sensor 11 and the temperature sensor 12 (S41). Therefore, when the internal pressure and temperature of the air mattress 100 are outside the set pressure and temperature ranges, the controller 10 repeatedly executes steps S37 to S39.

[0072] Next, after the air inflation device 1 is operated by selecting the power button 30 in step S32, the user can select any one of the first to third memory buttons 34 to 36 on the control panel 13 in which the set pressure is stored, without selecting the pressure adjustment button 32 (S50). Therefore, the controller 10 operates steps S34 to S41 at the pressure value set in any one of the first to third memory buttons 34 to 36 according to the user's selection.

[0073] FIG. 11 is a flowchart showing a method for setting the air pressure using the first through third memory buttons 34-36. After operating the air inflation device 1 by selecting the power button 30 on the control panel 13, the user selects one of the memory buttons 34-36 to save the set pressure values ​​(S51). When the user selects one of the memory buttons 34-36, the controller 10 displays the selected memory number on the display 33. When the user sets the pressure value by increasing or decreasing it using the pressure adjustment button 32, the controller 10 displays the pressure value on the display 33 (S52). After the pressure value is set, the controller 10 saves the set pressure value by pressing the selected one of the first through third memory buttons 34-36 for a certain period of time (S53). A message indicating that the pressure value set using the corresponding one of the first through third memory buttons 34-36 has been saved is displayed on the display 33, completing the saving process.

[0074] Thereafter, when the user presses the corresponding memory button 34-36 in which the set pressure value is stored among the first to third memory buttons 34-36 (S54) and then presses the air injection start / stop button 31, air is automatically injected at the pressure value set through the corresponding memory button 34-36 (S55). Therefore, the controller 10 operates steps S34 to S41 at the pressure value set in one of the first to third memory buttons 34-36 according to the user's selection.

[0075] The scope of the present invention is not limited to the above-described exemplary embodiments, and many other modifications based on the present invention will be possible by those skilled in the art within the technical scope described above. [Explanation of symbols]
