Description
Technical field
The utility model relates to a kind of air-flow switching mechanism, and particularly the air-flow switching mechanism that promotes air-flow air inlet, the certain function of pressure release start is used in a kind of air-inflating device inside of being located at.
Background technique
Press, with traditional on the market air-inflating device (such as vapour, the motor-vehicle tyre inflating gun) structure, usually the function that only has simple air inlet, if when the user imposes too much suction pressure to tire, then must do the pressure release action from cranked tire valve, doubt on not only affecting convenience and easily causing safely, and also can't do accurately tire pressure control of the utmost point, in view of this, then there is relevant industry to develop a kind of air-inflating device improved type structure kenel in having decompression function, with this series products, its early stage design as shown in Figure 1, be provided with a pressure release button A2 in inflating gun body A, finish air-suction state when the user decontrols handgrip A1, need press again pressure release button A2 and reach the pressure release action, so operate because air inlet must see through different fingers from the operation of pressure release, not only the action of operation has some setbacks, and long-time use more can cause user's hand uncomfortable.
Because the problems referred to above point, then there is the industry improvement to develop another kind and can controls simultaneously the known product of inflating that switches air inlet, decompression function by the single section of controlling, shown in Fig. 2 to 4, the known air-flow switching mechanism B1 that inflates product is located in the hollow groove B2 of air gun body B inside; Hollow groove B2 has an air input part B21, a B22 of pressure release section; Known air-flow switching mechanism B1 mainly finishes switch motion by a valve rod B3 and a valve seat B4 who is removable state, wherein valve rod B3 is located at the B22 of pressure release section of hollow groove B2, as the set handgrip C of the light compressed gas gun body of user B when (as shown in Figure 2), meeting so that valve rod B3 shrink back towards hollow groove B2, make the interior air-flow of tire discharge by the set relief hole B31 of valve rod B3 and reach the pressure release effect, and when the weight handgrip (as shown in Figure 3), valve rod B3 can continue inwardly to shrink back and pass valve seat B4, enter the B22 of pressure release section with barrier air, and make compressed air stream enter air input part B21 and reach the effect of giving vent to anger; Structure kenel by this consists of that the user can see through that the handgrip power is pressed in control and air inlet, pressure release switching function.
Yet the known product of inflating with air inlet, pressure release air-flow switching mechanism finds still to exist the following problems point in practical application experience:
Although known air-flow switching mechanism can switch air inlet, pressure release state by pressing power, but, when the user presses power not really the time, as shown in Figure 4, tend to occur broken away from the formation air inlet runner between valve seat B4 and the hollow groove B2, but this while valve rod B3 does not stop yet disappointing stream fully and causes air inlet and the simultaneous embarrassed shape of pressure release state, cause switch motion indefinite, allow the user be difficult to precisely be affectedly bashful the hand pressing force and switch air inlet, relief mode, and then impact operation smoothness and convenience.
