The working procedure that the present embodiment is described in detail in detail is as follows:
In the time that needs are inflated inflatable substrate, first, requirement according to user to inflatable substrate soft or hard degree, regulate the position of the second sensitive switch 53, specific operation are: this second knob part 553 of turn makes screw rod 551 drive nut part 552 to move on suitable position, this second sensitive switch 53 moves on suitable position with nut part 552 is movable, the second sensitive switch 53 from the distance of the second air pressure sensor film 54 more away from, it is just harder that inflatable substrate completes hardness after inflation, otherwise softer, in the time that the second knob part 553 is threaded on suitable position, diverter switch 52 has been touched portion 502 and has triggered and connect simultaneously.Then, this the first knob part 47 of turn, making to rotate press part 46, to drive the second control mechanism 26(be screw rod part) rotate, the rotation of the second control mechanism 26 and drive that to switch housing 23 movable downwards, and air flue 207 is communicated with between air outlet 206 and the 4th gas port 201, this suction port 205 is by the shell 10 internal communication external worlds, meanwhile, the pressure section 461 of this rotation press part 46 compresses the first sensitive switch 49, and, this positioning part 462 is located by a limited part 451 wherein, now, this low pressure blower device 20 is started working, rotated by motor 24 impeller 22, make extraneous air form air-flow, air-flow promotes the first one-way valve 13 and opens and enter in inflatable substrate.Along with the continuous rising of inflatable substrate internal air pressure, air pressure in this first cavity 401 constantly raises, the first air pressure sensor film 48 is upwards out of shape, in the time that inflatable substrate inside reaches default low pressure, this the first air pressure sensor film 48 promotes this yoke frame 42, the service portion 421 of yoke frame 42 acts on swing part 43 swing part 43 is swung, the swing of this swing part 43 drives rotary spacing part 45 to rotate by connecting rod 44, thereby make rotary spacing part 45 upper limit portions 451 depart from positioning part 462 spacing to rotating press part 46, this rotary spacing part 46 resets, pressure section 461 on rotary spacing part 46 departs from compressing the first sensitive switch 49, this low pressure blower device 20 quits work, meanwhile, under the Facilitation of diverter switch 52, this high-pressure blast device 30 is started working, drive two open/close mechanisms 33 to swing and open each other back and forth or closure by electromagnetic assembly 32, so gas is pressed in inflatable substrate, make the air pressure in inflatable substrate continue to raise, the air pressure of the 3rd cavity 501 also increases, to impel the second air pressure sensor film 54 to be upwards out of shape, in the time that inflatable substrate inside reaches preset high-pressure, this second sensitive switch 53 is triggered by the second air pressure sensor film 54, this high-pressure blast device 30 quits work.
After inflatable substrate loses heart on a small quantity, this the second air pressure sensor film 54 leaves compressing the second sensitive switch 53, this high-pressure blast device 30 starts automatically, continue inflatable substrate to carry out high-pressure aerated, until again reach preset high-pressure, the second sensitive switch 53 is triggered by the second air pressure sensor film 54 again, this high-pressure blast device 30 can quit work, so move in circles, make inflation remain on preset high-pressure state.
In the time that needs are bled to inflatable substrate, first, this second knob part 553 of turn rotates screw rod 551, thereby makes touch part 502 depart from compressing diverter switch 52, then, oppositely this first knob part 47 of turn, making to rotate press part 46 drives the second control mechanism 26 to rotate, the rotation of the second control mechanism 26 and drive that to switch housing 23 movable downwards, and air flue 207 is communicated with between suction port 205 and the 4th gas port 201, this air outlet 206 is by the shell 10 internal communication external worlds, simultaneously, protuberance 232 on this switching housing 23 presses on the push rod 131 of the first one-way valve 13, the first one-way valve 13 is opened, gas in inflatable substrate is successively by the first gas port 101, the 4th gas port 201, air flue 207, suction port 205, air-inlet cavity 202, discharge to the external world outlet chamber 203 and air outlet 206, meanwhile, the pressure section 461 of this rotation press part 46 compresses the first sensitive switch 49, and, this positioning part 462 is located by another limited part 451, now, this low pressure blower device 20 is started working, and is rotated by motor 24 impeller 22, makes the gas in inflatable substrate form air-flow to discharge toward extraneous fast, along with the continuous decline of inflatable substrate internal air pressure, air pressure in this first cavity 401 constantly declines, the first air pressure sensor film 48 is upwards out of shape, in the time that gas in inflatable substrate is extracted out completely, this the first air pressure sensor film 48 promotes this yoke frame 42, the service portion 421 of yoke frame 42 acts on swing part 43 swing part 43 is swung, the swing of this swing part 43 drives rotary spacing part 45 to rotate by connecting rod 44, thereby make rotary spacing part 45 upper limit portions 451 depart from positioning part 462 spacing to rotating press part 46, this rotary spacing part 46 resets, pressure section 461 on rotary spacing part 46 departs from compressing the first sensitive switch 49, this low pressure blower device 20 quits work, complete the operation of bleeding.
Design focal point of the present utility model is: by utilizing knob part to drive screw rod, nut part is moved around along screw axial, thereby drive sensitive switch away from or near air pressure sensor film, to have realized the stepless adjustment of the distance to sensitive switch, be convenient to the inflatable substrate that user obtains most suitable hardness, and it is simple in structure, the fast and easy operating also extremely, for user's use brings more convenience.
