Push type water tap with automatic closing functions

A push-type water tap having an automatic closing function, the push-type water tap comprising:

• a main body having an inner space defining an upper chamber and a lower chamber, said inner space having a transverse middle partition formed between said upper chamber and said lower chamber, said main body having an inlet pipe extending vertically and communicating with said lower chamber, said main body having a threaded hole formed at an upper center of said upper chamber, said transverse middle partitions having a through hole formed in a center thereof;
• a through valve tube positioned vertically in a center of said upper chamber of said main body, said through valve tube having a top connected to a lock-joining seat, said lock-joining seat having a male threaded portion threadedly engaged with said threaded hole of said main body, said locking-joining seat having a vertical guiding hole with an O-ring set therein, said through valve tube having a discharge guiding hole set laterally therethrough and a water stop ring flange positioned at a bottom thereof;
• a bottom tube positioned vertically into a center of said lower chamber of said main body, said bottom tube having an upper portion extending through said through hole of said transverse middle portion, said bottom tube having a top end linked to a bottom of said through valve tube, said bottom tube having an inlet guiding hole formed laterally therethrough and a sealing surface at a bottom thereof;
• a lifting valve lever having a top and a lever body and a bottom, said lever body translatably positioned into said vertical guiding hole of said locking-joining seat and said through valve tube, said top of said lifting valve lever extending from a top of said locking-joining seat, said bottom of said lifting valve lever extending into said bottom tube and having a stop ring abuttable onto said water stop ring flange so as to stop a flow of water;
• a push button removably affixed to said top of said lifting valve lever and covering an exterior of said top of said locking-joining seat;
• a restoring spring positioned between said top of said lifting valve lever and said locking-joining seat so as to resiliently support said lifting valve lever and said push button;
• a one-way check ring sleeved onto a periphery of said bottom of said lifting valve lever so as to move in correspondence with said lifting valve lever, said one-way check ring having a tapered cross-section so as to maintain contact with an inner wall of said bottom tube so as to prevent water from flowing downwardly between said bottom of said lifting valve lever and said inner wall of said bottom tube;
• a resettable regulating space defined by a gap between said bottom of said lifting valve lever and said sealing surface of said bottom tube;
• a resettable regulating water channel formed at said bottom of said lifting valve lever, said resettable regulating water channel having a radial channel and an axial tapered channel interconnected to each other such that water can be guided into said radial channel from said inlet guiding hole, said axial tapered channel connected downwardly with said resettable regulating space;
• a holding groove formed vertically in a center of said lifting valve lever, said holding groove having an upper end extending to said top of said lifting valve lever and a lower end extending to said bottom of said lifting valve lever, said holding groove connected to said axial tapered channel, said holding groove having a female threaded section formed therein;
• and
• a flow regulating screw assembled into said holding groove, said flow regulating screw having a male threaded section mated with said female threaded section of said holding groove, said flow regulating screw having a tooling slot formed at a top thereof, said flow regulating screw having a tapered column formed at a bottom thereof, said tapered column having a lower end mating with and positioned within said axial tapered channel of said resettable regulating channel, said tapered column having said lower end adjustably positioned adjacent an end of said radial channel so as to as to control a flow of water through said radial channel.
