These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1 and Figure 2 As shown, the utility model provides an inflating device for a multi-unit inflatable mattress, including a shell and a power supply unit 10, an operating unit 20, an indication unit 30, a control unit 40, pressure detection units 50a, 50b, 50c, an inflation solenoid valve 60, a deflation solenoid valve 70 and an air pump unit 80 arranged in the shell.

[0025] The operating unit 20 includes a plurality of buttons arranged on the operating panel of the inflator. Figure 2 As shown, a power button 201, a channel selection button 202, a pressure upshift button 203, a pressure downshift button 204 and a memory button 205 are provided.

[0026] The indication unit 30 includes a plurality of display devices arranged on the operation panel of the inflatable device, and gives corresponding indications to the key operations of the operation unit. Figure 2 As shown, it includes a power indicator light 301, channel indicator lights 302, 303, 304, and a character display device 305. More specifically, the character display device can be a digital tube or LCD display screen that displays multiple characters.

[0027] Usually, the operation unit 20 and the indication unit 30 are arranged on the same circuit board and then connected to the control unit 40 in a unified manner.

[0028] The control unit 40 is a circuit board on which a microprocessor and peripheral circuits are integrated. The microprocessor runs a control program to perform inflation control. The control unit 40 is set with a preset pressure value; and performs the following operations: according to the instructions given by the operating unit 20, the preset pressure value is adjusted, the airway is selected and the air pump 80 is controlled to inflate the inflation unit of the inflatable mattress connected to the selected airway.

[0029] Specifically, the control unit 40 can perform self-test, control the inflation pump 80 to inflate, and other actions after receiving the power-on command from the power button 201. The control unit 40 can switch the inflation channel after receiving the inflation channel switching command from the channel selection button 202. The inflation channels are switched in the order of 1, 2, and 3. The control unit 40 increases the pressure after receiving the pressure increase command from the pressure increase button 203, and relieves the pressure after receiving the pressure reduction command from the pressure decrease button 204. The control unit 40 includes a timing unit 401, which can be implemented by software or hardware. When inflation is started, the timing unit 401 starts timing, and when inflation is stopped, the timing unit 401 is reset; when the timing of the timing unit 401 reaches a preset time, inflation is stopped. The timing unit 401 can provide overcharging protection in abnormal situations.

[0030] In this embodiment, three air passages are provided to be connected to three independent inflatable units of the air mattress respectively, so as to inflate each inflatable unit independently.

[0031] Each airway extends a hose connected to a pressure detection unit, and the pressure detection units 50a, 50b, and 50c detect the pressure value of the corresponding airway. The control unit 40 performs inflation and deflation control according to the difference between the pressure value detected by the pressure detection unit and the preset pressure value. Specifically, each group of pressure detection units includes a pressure sensor and an amplifying circuit thereof. The pressure sensor adopts a bridge pressure sensor, which can accurately obtain the pressure change of the airway.

[0032] In this embodiment, each pressure detection unit 50 and the control unit 40 are integrated on the same circuit board to simplify the circuit connection structure.

[0033] In this embodiment, the inflation solenoid valve 60 is a multi-way solenoid valve, including multiple controlled flow channels, which are connected by a common end, namely the input end of the inflation solenoid valve 60. Each controlled flow channel has an independent control signal connected to the control unit 40, receives the inflation instruction from the control unit 40, and controls the connection or disconnection of the corresponding air channel with the air pump unit 80.

[0034] The deflation solenoid valve 70 is a multi-way solenoid valve. Similarly, each controlled flow channel of the deflation solenoid valve 70 has an independent control signal connected to the control unit 40, receives the deflation instruction of the control unit 40, and controls the connection or disconnection of the corresponding air channel with the deflation channel.

[0035] The use of multi-way solenoid valves can improve the integration of equipment and facilitate control.

[0036] The inflatable device of the utility model has the following technical effects: each inflatable unit of a multi-unit inflatable mattress can be inflated independently to meet the different softness and hardness requirements of multiple people when using it.

[0037] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
