[0015] As described above, compared with the prior art, this utility model has the following advantages: When the push knob is in its lowest position, the water inlet of the flow shaft is located below the sealing ring. At this time, the water inlet cannot connect with the water outlet channel, and the spray gun is in a closed state. When the push knob is pushed upward, the push knob drives the flow shaft to move upward. As the flow shaft moves upward, the water inlet gradually moves above the sealing ring, and the water inlet connects with the water outlet channel. As the flow shaft continues to rise, more of the water inlet protrudes above the sealing ring, resulting in a larger water flow through the water inlet. When the push knob is pushed to its highest point, the water flow through the water inlet is at its maximum. Similarly, when the push knob drives the flow shaft to move downward, less of the water inlet protrudes above the sealing ring until the water inlet is completely below the sealing ring, at which point the spray gun is in a closed state again. This utility model allows the user to adjust the position of the push knob according to their needs, thereby adjusting the spray gun flow rate and meeting diverse water output requirements.

In this way, the lower spindle 2, the upper spindle 1, the nozzle assembly 6 and the housing 9 form a complete connection.

[0041] Reference Figures 1 to 11The design principle of this utility model is as follows: When the push knob 5 is in its lowest position, the water inlet 31 of the flow shaft 3 is located below the sealing ring 23. At this time, the water inlet 31 cannot connect with the water outlet channel 11, and the spray gun is in a closed state. When the push knob 5 is pushed upward, the push knob 5 drives the flow shaft 3 to move upward. As the flow shaft 3 moves upward, the water inlet 31 will gradually be located above the sealing ring 23, and the water inlet 31 will connect with the water outlet channel 11. As the flow shaft 3 continues to rise, more of the water inlet 31 is exposed above the sealing ring 23, and the water flow rate through the water inlet 31 is greater. When the push knob 5 is pushed to its highest point, the water flow rate through the water inlet 31 is at its maximum. Similarly, when the push knob 5 drives the flow shaft 3 to gradually move downward, less of the water inlet 31 is exposed above the sealing ring 23, until the water inlet 31 is completely below the sealing ring 23, at which point the spray gun is in a closed state again.

[0042] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
