[0045] To facilitate the installation of the valve stem 112 and the spring 118, and to ensure that the valve stem 112 and the valve seat 111 cooperate to maintain a sealing state, the elastic device includes: a spring 118 and a base plate 119 fixedly disposed on the core 101 to prevent fluid from flowing out from the bottom of the valve core hole 110. One end of the spring 118 abuts against the bottom of the valve stem 112 and the other end abuts against the base plate 119.

[0046] To improve the stability of the spring 118, a first guide hole 120 is provided at the bottom of the valve stem 112, and a second guide hole 121 matching the first guide hole 120 is provided on the base plate 119.

[0047] To facilitate the user in pressing the valve stem 112, a pressing device is also provided on the valve stem 112 to facilitate pressing the valve stem 112;

[0048] The pressing device includes: a hinge seat 122 disposed on the core 101, and a lever block 123 hinged to the hinge seat 122, the bottom of the lever block 123 abutting against the top of the two valve stems 112.

[0049] In order to protect the core 101, a protective shell 124 is also provided on the core 101 to facilitate the user's horizontal grip and to protect the core 101;

[0050] The protective shell 124 has a first pin hole 125, and the core 101 has a second pin hole 126 corresponding to the first pin hole 125. The protective shell 124 and the core 101 are fixed by pins 127.

[0051] To facilitate the positioning of the protective shell 124, the spray cover 104 is provided with a limiting ring platform 128 for abutting against the protective shell 124.

[0053] To facilitate the connection of the shower hose, the core 101 is also provided with a connecting thread 130 for connecting the shower hose.

[0054] Working principle: During assembly, the user first installs the first sealing ring 113 and the second sealing ring 115 on the valve stem 112, then inserts the valve stem 112 into the valve core hole 110, then installs the spring 118 on the second guide hole 121 of the base plate 119, aligns the first guide hole 120, and covers the core 101 with the base plate 119, then fixes it on the core 101 by ultrasonic welding. Next, the positioning tube 108 on the spray cover 104 is inserted into the positioning ring groove 109, ensuring that the mounting ring platform 106 abuts against the abutment platform 107, and the positioning tube 108 abuts against the positioning ring groove 109. At this time, the two can be fixed by ultrasonic welding. Then, the counterweight 129 is placed on the core 101, and the protective shell 124 is sleeved on the core 101. Positioning is completed by the pin 127. Finally, the lever block 123 is installed on the hinge seat 122 to complete the installation.

[0055] In use, fluid enters the core 101 from the main channel 102 and flows to the two valve core holes 110. At this time, the user presses one end of the lever block 123, causing the valve rod 112 to push the spring 118 downward, thereby contacting the first sealing ring 113 and the valve seat 111 to engage. The fluid can then flow from the valve core hole 110 to the water outlet channel 114, and then through the water outlet channel 114 to the water outlet 103, and finally out from the spray hole 105. Depending on the lever block 123 pressed, the spray gun has two water outlet modes: one is a single-hole direct spray from the positioning ring groove 109 to the spray cover 104, and the other is a multi-hole spray from the core 101 to the cavity between the core 101 and the spray cover 104.
