as the lower connector and the upper connector are inserted and connected deeply and are not completely connected and coupled, the top of the lower control valve is propped against the steel balls, the upper propping force of the lower control valve to the steel balls is smaller than the acting force of the return elastic piece to the steel balls, the steel balls in the upper water injection assembly are in a state of covering the upper opening of the hollow connecting sleeve, namely, the water injection channel on the upper water injection assembly 1 is in a closed state, the lower control valve in the lower water injection assembly is subjected to the pressure of the steel balls to open the water injection channel of the lower sleeve, the lower water injection channel in the lower water injection assembly is opened, and the water injection channel is in a pre-opened state of being closed and opened up and down, as shown in fig. 6.
As the lower connector continues to be inserted into the upper connector until the lower connector is completely connected to the coupling position, as shown in fig. 7, i.e. when the upper water injection assembly 1 and the lower water injection assembly are inserted into the bottom to complete the connection, the lower control valve of the lower water injection assembly 2 opens the water injection channel of the lower sleeve, and simultaneously the lower water injection assembly overcomes the elastic force of the return elastic member 12 to push up the steel balls, so that the steel balls leave the upper opening of the hollow connecting sleeve, and the water injection channel on the upper water injection assembly 1 is opened, and the water injection channel is in a channel state.
In the process of separating the lower connector from the upper connector, the water injection channel is always butted into a pipe, the water injection channel is turned from a passage state to a pre-opening state of which the upper part is closed and the lower part is opened, the lower control valve of the lower water injection assembly 2 leaves from a lower threshold stop position, the supporting force of the lower threshold stop structure on the driving rod is released, the upward pushing force of the driving rod on the steel ball is weakened to be smaller than the resilience force of the return elastic piece on the steel ball, the steel ball covers the upper opening of the hollow connecting sleeve, the water injection channel on the upper water injection assembly 1 is closed, and meanwhile, the stroke of the driving rod in the lower water injection assembly is not separated from the steel ball. Along with the continuous separation process of the upper water injection component and the lower water injection component, the water injection channel is kept to be a pipe, the driving rod is separated from the steel ball, the driving rod drives the sealing plug ring 25 to move upwards under the action of the pressure-bearing spring, the inclined sealing surface of the sealing plug ring 25 is in abutting fit with the inner edge of the bottom of the upper water cavity, the inner diameter water through hole of the lower sleeve is plugged, the water injection channel of the lower water injection component is closed, and the water injection channel is in a butt joint state.

Because the butt joint position is that the butt joint is in a tubular state and a pre-opening state in the coupling and uncoupling process, for the water injection channel, the upper water injection component serving as a flowing water active inlet is started to be closed last and first, and the lower water injection component serving as a flowing water passive outflow port is started in advance in the coupling process, the influence of the excessive initial pressure of flowing water on the water injection channel is effectively avoided, the lower water injection component is closed relatively to the upper water injection component in the uncoupling process, the smooth outflow of residual water in the water injection channel after the active inlet is closed is facilitated, and after the upper water injection pipeline and the lower water injection pipeline are closed, compared with the conventional upper sleeve and lower sleeve plane butt joint, the invention adopts a plurality of convex rib rings 141 distributed at intervals to form tight fit sealing on the outer surface wall of the upper section of the lower sleeve 21, the sealing is multiple, the lower sleeve is always kept tight fit sealing with the outer surface wall of the upper section of the lower sleeve 21 after entering the hollow connecting sleeve 14, the lower sleeve is guaranteed to be in butt joint with the upper sleeve in the butt joint position and the complete coupling position, and the wall pipe is sealed outwards and separated.
The water injection mechanism is more adaptive to the upper water injection type temperature control coupler, and the upper water injection component and the lower water injection component can be directly or reversely installed on the spring type temperature control coupler, namely, the lower water injection component is installed in the upper connector, and the upper water injection component is installed in the lower connector, so that the water injection mechanism is more reasonable and beneficial to flow control.
