Specifically, switch actuator 11 be suitable for the axial movement along switch mounting hole 1212 in the first predeterminated position and It is switched between second predeterminated position；When switch actuator 11 is located at the first predeterminated position, switch actuator 11 drives list Control device gas outlet 1222 is opened to valve 13, and switch actuator 11 is connected between air pump switch 14 and control unit 1213 Electrical connection；When switch actuator 11 is located at the second predeterminated position, switch actuator 11 drives check valve 13 to close control dress Gas outlet 1222 is set, and switch actuator 11 disconnects being electrically connected between air pump switch 14 and control unit 1213.

More specifically, it when needing to be inflated inflatable body, is applied to the switch press portion 112 of switch actuator 11 Add external force, i.e. push switch press section 112, the switch insertion switch guiding groove 1223 of guide portion 111 is with directing switch actuator 11 The control device gas outlet 1222 that is axially facing along switch mounting hole 1212 is moved to the first predeterminated position.In switch actuator 11 In moving process, for switch actuator 11 with ovable valve stem 133 along the axial movement of switch mounting hole 1212, the first of valve rod 133 is sliding Block 1332 and is distally-oriented to proximal slide, the second sliding block from the first planing surface 1321 along the axial movement of switch mounting hole 1212 1333 from the proximal slide of the second sliding block slide slot 1325 to distal end, and slides into proximal end from the distal end of the second planing surface 1322, That is the first sliding block 1332 and the second sliding block 1333 are rotated and are moved axially in supporting element through-hole section 132, are carried on the back with band moving valve plate 134 Control device gas outlet 1222 is opened from the direction movement towards control device gas outlet 1222；When control device gas outlet When 1222 opening, the switch main body portion 113 of switch actuator 11 is single to connect air pump switch 14 and control against air pump switch 14 Electrical connection between member 1213, the thus starting of air pump 15 operating；When air pump 15 operates, the fluid of inflatable body exterior space is successively Via control device air inlet 1211, control device chamber 1221, control device gas outlet 1222, flow transition chamber 163, gas Pump steam inlet 1511 enters fan blade chamber 1533, then pressurizes through fan blade 154, the fluid after pressurization successively goes out via blade cover again Port 1531, the rest part of air pump chamber, air pump gas outlet 1521 flow into inflatable body internal cavities (not shown), it is thus right Inflatable body is inflated.

When the switch press portion 112 of push switch actuator 11 again, switch actuator 11 is made in the rebound of spring 135 The second predeterminated position (restoring to initial position), valve are moved axially to along switch mounting hole 1212 with lower driving stem 133 Direction of the bar 133 with moving valve plate 134 towards control device gas outlet 1222 is mobile with shutoff control unit gas outlet 1222, and Switch main body portion 113 disconnects being electrically connected between air pump switch 14 and control unit 1213, thus stops filling inflatable body Gas.

Specifically, second is sliding when switch press portion 112 in switch actuator 1111 of push switch actuator again Block 1333 first deviates from the axial movement of the second planing surface 1322 along the axial direction of switch mounting hole 1212, then slides from adjacent second The distal end in face 1322 is slided to proximal end, and continues to slide into the second sliding block slide slot 1325, later from the second sliding block slide slot 1325 are distally-oriented to proximal slide；In 1333 sliding process of the second sliding block, the first sliding block 1332 is from adjacent first planing surface Then 1321 proximal slide is detached from the first planing surface along switch mounting hole 1212 and is axially facing switch mounting hole to distal end 1212 is mobile, until the first sliding block 1332 is connected with switch, the contact of portion 115 is to stop valve rod to continue to slide.

As shown in Figure 12 and Figure 13, the utility model also shows another exemplary embodiment, the exemplary embodiment party The difference of formula and above-mentioned example embodiment is only in that: control device shell 122 is close to control device gas outlet 1222 Place has control device gas outlet flange 1228；The valve block 134 of check valve 13 may include valve block extension 1343, valve block extension 1343 are suitable for switching between compressive state and extended mode, in the illustrative embodiments, valve block extension 1343 For flexible film.In addition to the difference, the illustrative embodiments and above-mentioned example embodiment are all the same, and phase It is in it and has been described in above, hereafter will not be described in great detail.

Air pressure when the electric air pump component 1 using the illustrative embodiments inflates inflatable body, inside inflatable body Less than the air pressure of inflatable body exterior space, push switch actuator 11 is at this time to drive check valve 13 to open control device gas outlet 1222, and switch actuator 11 is made to connect the electrical connection between air pump switch 14 and control unit to start operating air pump 15, so that the fluid of inflatable body exterior space flows (i.e. fluid flows from outside to inside) towards inflatable body, at this point, check valve 13 Valve block extension 1343 is held in compression with by the pressure of fluid, without coating control device gas outlet 1222, by The fluid of this permission inflatable body exterior space flows to the inside of inflatable body, to be inflated to inflatable body.

After completing to inflate inflatable body, the air pressure inside inflatable body is greater than the air pressure of inflatable body exterior space, at this point, working as The accidental push switch actuator 11 of user makes the opening control device gas outlet 1222 of check valve 13 and air pump 15 does not operate (example Such as, air pump 15 breaks down or cuts off the power supply supply of electric air pump component when air pump being caused not operate) when, inside inflatable body Fluid tend to towards inflatable body exterior space flow (i.e. fluid flows from inside to outside), the valve block extension of check valve 13 1343 are in extended mode (as shown in figure 13), and cover control device gas outlet flange 1228, thus valve block extension 1343 Hermetic seal is formed with control device gas outlet 1222, thus prevents the fluid leakage inside inflatable body to the external sky of inflatable body Between.In the illustrative embodiments, the valve block extension 1343 of extended mode is in umbrella.

In conclusion inflatable body will be formed by being set to the valve block extension 1343 of check valve 13 and valve block main part 1342 The effect of sealing.When not inflated to inflatable body, the closing of check valve 13 and seal control device gas outlet 1222.When to inflatable body When inflation, check valve 13 is opened, and fluid is blown open by export-oriented inflatable body internal flow, valve block extension 1343 and compression shape is presented State does not coat control device gas outlet 1221.In addition, inflate and complete when inflatable body to avoid maloperation that inflatable body is caused to lose heart, And power supply is removed for seasonable, if rotary switch actuator 11 opens check valve 13, but air pump 15 is supplied because of non-transformer at this time Inoperative, extended mode will be presented in valve block extension 1343, be coated on control device gas outlet 1222, so that inflation is intracorporal Gas will not leak to the outside.
