1. A door closer capable of adjusting its closing speed for use with a door and a door frame, comprising: a gas adjusting apparatus arranged on the door frame,a driving apparatus arranged on the door, anda lever having opposite ends, with one end of the lever connected to the gas adjusting apparatus
1. A door closer capable of adjusting its closing speed for use with a door and a door frame, comprising: a gas adjusting apparatus arranged on the door frame,a driving apparatus arranged on the door, anda lever having opposite ends, with one end of the lever connected to the gas adjusting apparatus and the other end connected to the driving apparatus;whereby the gas adjusting apparatus and the driving apparatus are connected by the lever to control closing of the door;the gas adjusting apparatus comprising: a sliding rail adapted to be arranged on the door frame;a sliding member slidably mounted in the sliding rail,a hermetic chamber formed by the sliding member and the sliding rail,an adjusting member for adjusting an exhaust of the hermetic chamber, andconfigured on a side wall of the hermetic chamber; andthe lever configured on the sliding member;wherein the driving apparatus comprises; a receiving chamber adapted for mounting on the door,an elastic component in the receiving chamber for storing resilience,a pulley adapted to be rotatably mounted on the door;a driving cam operatively connected to the pulley for transferring the resilience to the pulley; andwherein the lever is fixedly connected to the pulley;whereby opening the door compresses the elastic component and slides the sliding member to increase the volume of the hermetic chamber; andwhereby when the open door is released, the elastic member decompresses while the sliding member slides to discharge gas from the hermetic chamber, thereby controlling closing speed of the door. 2. The door closer of claim 1, wherein the sliding member comprises a sliding block, a piston and a joint rod for connecting the sliding block and the piston; a hermetic chamber is formed by the piston and the sliding rail, the lever is hinged to the sliding block. 3. The door closer of claim 1, wherein the sliding member is provided with an air-in configuration which comprises a groove on the periphery of the sliding member, a seal ring movably configured in the groove, an air intake through the sliding member; a first side wall and a second side wall are formed at the groove, wherein the first side wall is adjacent to the hermetic chamber while the second side wall is opposite the first side wall;the air intake being configured on the first side wall;a gap between the second side wall and an inner side wall of the sliding; andthe second side wall being inclined from bottom of the groove. 4. The door closer of the claim 1, wherein the elastic component is a spring. 5. The door closer of claim 4, wherein the pulley is a cam, and the driving components comprises a driving piston configured at one end of the spring, and a cam roller on the driving piston;the cam roller being tangent to the profile of the cam;the other end of the spring being connected with a side wall of the receiving chamber. 6. The door closer of claim 5, wherein a housing is configured on the door, and receives the driving apparatus. 7. The door closer of claim 6, wherein the gas adjusting apparatus is embedded into the door frame, and the housing is embedded into the top of the door. 8. The door closer of claim 6, wherein the adjusting member is a regulating valve. 9. The door closer of claim 8, wherein the gas adjusting apparatus is embedded into the door frame, and the housing is embedded into the top of the door. 10. The door closer of claim 8, wherein the sliding rail is a cylinder, the regulating valve is configured on one end of the hermetic chamber, a vent is configured on the other end of the hermetic chamber, and a slot for the lever is arranged on the cylinder. 11. The door closer of claim 4, wherein the pulley is a gear, the driving component is a rack engaged with the gear, the rack is connected to one end of the spring, and the other end of the spring is connected with a side wall of the receiving chamber. 12. The door closer of claim 11, wherein a housing is configured on the door, and receives the driving apparatus. 13. The door closer of claim 12, wherein the gas adjusting apparatus is embedded into the door frame, and the housing is embedded into the top of the door. 14. The door closer of claim 12, wherein the adjusting member is a regulating valve. 15. The door closer of claim 14, wherein the sliding rail is a cylinder, the regulating valve is configured on one end of the hermetic chamber, a vent is configured on the other end of the hermetic chamber, and a slot for the lever is arranged on the cylinder. 16. The door closer of claim 14, wherein the gas adjusting apparatus is embedded into the door frame, and the housing is embedded into the top of the door. 17. An adjustable closer for a screen door hinged to a door frame for movement between open and closed positions, comprising; a pneumatic cylinder for mounting to one of the door frame and the door;a slide member slidably mounted in the pneumatic cylinder to define an air chamber in the pneumatic cylinder;a spring mounted in the other of the door frame or the door;a lever having opposite ends connected to the slide member and to the spring;the spring compressing when the door opens and decompressing when the door closes;the lever pulling and pushing the slide member within the pneumatic cylinder as the door opens and closes, respectively; anda valve on the pneumatic cylinder to control exhaust from the chamber as the door closes.
