Referring to FIGS. 2 to 4, the adapter of the present invention comprises a body 3, seal rings 4, a stationary ceramic disk 5, a movable ceramic disk 5, a plate 7 and a knob 8.
The body 3 is connected to a liquid bottle 2 in any known way. A pump connector 9 and a tire connector 10 are respectively connected to the body 3. The pump connector 9 is connected to a pump by a hose or by directly connected with the pump. The tire connector 10 is connected to the valve of the tire. As shown in FIG. 4, the body 3 has four independent paths which are an air intake path, an air outgoing path 11, a liquid outgoing path 12 and a tire connection path. The air outgoing path 11 and the liquid outgoing path 12 are connected to the liquid bottle 2. The air intake path and the tire connection path are respectively connected with the pump connector 9 and the tire connector 10. The body 3 has an installation face in which four independent holes are defined, the four holes are an air inlet 13, an air outlet 15, a liquid outlet 16 and a tire connection hole 14. The air inlet 13, the air outlet 15, the liquid outlet 16 and the tire connection hole 14 are respectively connected with the air intake path, the air outgoing path 11, the liquid outgoing path 12 and the tire connection path. The stationary ceramic disk 5 is located on the installation face of the body 3 and the stationary ceramic disk 5 is sealed to the body 3 by the seal rings 4. The movable ceramic disk 6 is located on the stationary ceramic disk 5. The knob 8 is connected on the movable ceramic disk 6 so as to rotate the movable ceramic disk 6 relative to the stationary ceramic disk 5. The plate 7 is located between the knob 8 and the movable ceramic disk 6. The stationary ceramic disk 5 is sealed with the body 3 and the movable ceramic disk 6. The movable ceramic disk 6 has a first smooth face and the stationary ceramic disk 5 has a second smooth face, the first and second faces are ground to be fine and smooth, so as to be snugly matched to each other.
As shown in FIGS. 5 and 6, the stationary ceramic disk 5 has four independent units which are an air intake unit 17, an air outgoing unit 18, a liquid outgoing unit 19 and a tire connection hole unit 20. The air intake unit 17, the air outgoing unit 18, the liquid outgoing unit 19 and the tire connection hole unit 20 are respectively connected with the air inlet 13, the air outlet 15, the liquid outlet 16 and the tire connection hole 14. The movable ceramic disk 6 has a first slot 21 and a second slot 22.
When the movable ceramic disk 6 is rotated to the air-pumping position by operating the knob 8, the air intake unit 17 communicates with the tire connection hole unit 20 via the first slot 21. The pressurized air enters into the air inlet path via the pump connector 9, the pressurized air then is introduced into the tire via the air inlet 13, the air intake unit 17, the first slot 21, the tire connection hole unit 20, the tire connection hole 14, the tire connection path, and the tire connector 10 so as to pump the tire.
When the movable ceramic disk 6 is rotated to the liquid-introducing position by operating the knob 8, the air intake unit 17 communicates with the air outgoing unit 18 via the first slot 21. The liquid outgoing unit 19 communicates with the tire connection hole unit 20 via the second slot 22. The pressurized air from the pump enters into the air inlet path via the pump connector 9. The pressurized air enters into air intake path, the air inlet 13, the air intake unit 17, the first slot 21, the air outgoing unit 18, the air outlet 15, the air outgoing path 11 and finally enters into the liquid bottle 2. The pressure in the liquid bottle 2 pushes the liquid in the liquid bottle 2 to flow through the liquid outgoing path 12, the liquid outlet 16, the liquid outgoing unit 19 and enters into the second slot 22. When the liquid passes through the second slot 22, the liquid enters into the tire via the tire connection hole unit 20, the tire connection hole 14, the tire connection path and the tire connector 10. When the liquid in the liquid bottle 2 completely flows into the tire, the user then switches the knob 8 to the air-pumping position to inflate the tire without detaching any hose.
As shown in FIG. 7, in order to prevent the movable ceramic disk 6 from overly rotated to cause the effective air-pumping position and the liquid-introducing position not work properly, the plate 7 is used. A first restriction portion 24 and a second restriction portion 23 extend from the periphery of the plate 7. A sliding portion 25 extends from the periphery of the movable ceramic disk 6. The sliding portion 25 slides between the first and second restriction portions 24, 25, so that when the movable ceramic disk 6 is rotated to make the sliding portion 25 contact the first restriction portion 24, the position is the effective air-pumping position. Similarly, when the movable ceramic disk 6 is rotated to make the sliding portion 25 contact the second restriction portion 23, the position is the effective liquid-introducing position.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
