Automatized speedy coolant jetting device for the car interior

Claim 1

An automatic speedy coolant jetting device for mounting to a central ceiling area of a car roof comprising: a container comprising separating walls defining lower, middle and upper chambers, said container being open below the lower chamber and closable by a cover plate, said container having installation ears along a top edge thereof for attachment of said container to the car ceiling; a jet can having a base mounted through the open lower chamber and fitted within the lower chamber, and a valve extending upwardly through openings in said separating walls whereby said valve extends through the middle chamber and into the upper chamber, said jet can being loaded with a mixture of a coolant liquid and a jet-actuating air, wherein said valve has at least two symmetrically arranged orifices maintained within the middle chamber, at least one of the separating walls defining the middle chamber being shaped to form a plurality of flat, cone shaped jet gates, and wherein said valve has, at a top end thereof, an arc driven plate; a starting gear and a PC board arranged on a bottom floor of said upper chamber, wherein said starting gear comprises: a motor having an output shaft; a main gear connected to the output shaft of said motor; a reducing gear driven by said main gear, which delivers a reducing speed; a follower having a driving arm able to press said arc driven plate of said valve, wherein said driving arm is a small circular bar having one end vertically connected to a circumferential edge of the follower and sleeved with a roller; and wherein said PC board is arranged with an IC time control circuit; a delay circuit; a shifter; wherein said PC board is connected through a power lead to a microswitch behind a handle of a car door and wherein the shifter commands that conduction be made between the control circuit and the microswitch; the microswitch able to conduct open the power source of the control circuit and, through the delay circuit, to start the motor whose operation is controlled, or stopped, by the IC time control circuit; whereby, when activated, the starting gear will actuate said valve causing coolant to be sprayed through the jet gates to effect cooling of the car.
