[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1 to 6 As shown, this embodiment provides a shower head, including a water inlet handle 1 and a handle rear shell 2. The water inlet handle 1 has a first water inlet channel 101, and the water inlet end of the first water inlet channel 101 is connected to a water inlet pipe. The handle rear shell 2 has a second water inlet channel 201, and the water outlet end of the first water inlet channel 101 is connected to the water inlet end of the second water inlet channel 201. A water channel plate 6 is installed in the handle rear shell 2. A connecting cover 7 is installed on the water inlet side of the water channel plate 6. The connecting cover 7 and the water inlet side of the water channel plate 6 form a connecting cavity 701. A push-to-switch button 3 is provided at the connecting cavity 701. The water channel plate 6 has a first water channel 601, a second water channel 602, a third water channel 603, and a fourth water channel 604. The end of the third water channel 603 is connected to a fourth mode spray nozzle 5. A quick-stopping component is provided between the end of the third water channel 603 and the fourth mode spray nozzle 5.

[0025] The rinsing mode of this utility model is achieved through the fourth mode water spray nozzle 5, which is installed at the rear of the handle rear shell 2. This allows for a rinsing method similar to direct water pipe rinsing, making operation more convenient. Pressing the switch button 3 is used to switch between different modes. The quick-stop water component allows for quick water stop when switching modes, making it more convenient in actual use.

[0026] The solution is further optimized. The quick-stopping component includes a water passage hole at the end of the third water channel 603. A movable ball 502 is provided on the side of the water passage hole near the fourth mode water nozzle 5. A spring 501 is provided between the movable ball 502 and the fourth mode water nozzle 5. The end of the third water channel 603 and the fourth mode water nozzle 5 are connected by a connecting channel 608. The movable ball 502 and the spring 501 are located in the connecting channel 608.

[0027] With the cooperation of spring 501 and movable ball 502, water can only be sprayed out through the fourth mode spray nozzle 5 when the water pressure exceeds the elastic force of spring 501. When the water pressure does not meet the requirements (i.e., mode switching or water valve closing), the fourth mode spray nozzle 5 can be quickly closed under the elastic force of spring 501, avoiding the inconvenience caused by the water flow not closing in time during rinsing.

[0028] The design is further optimized by installing a spray plate 4 on the water spray side of the handle rear shell 2. The spray plate 4 is provided with a first mode spray nozzle 401, a second mode spray nozzle 402, and a third mode spray nozzle 403. The first mode spray nozzle 401 is connected to the second water channel 602, the second mode spray nozzle 402 is connected to the fourth water channel 604, and the third mode spray nozzle 403 is connected to the first water channel 601.

[0029] To further optimize the design, the switching button 3 is rotated and connected to the water channel plate 6. The top surface of the switching button 3 is in contact with a drive pin 9, which is equipped with an adjustment valve for switching the water spray mode.

[0030] The scheme is further optimized. The regulating valve includes a rotary valve 8 that is movably installed in the waterway plate 6. The rotary valve 8 is located in the connecting cavity 701. An opening 801 is provided on the rotary valve 8. The rotary valve 8 rotates 90 degrees after being pressed once by the pressing drive component. The opening 801 connects to one of the first waterway 601, the second waterway 602, the third waterway 603, and the fourth waterway 604. A spring is installed between the rotary valve 8 and the connecting cover 7.

[0031] Further optimization of the scheme: the pressing drive component includes several first oblique protrusions 802, which are fixedly connected to the bottom surface of the rotary valve 8 at equal intervals along the circumference. The water channel plate 6 has four water passage grooves 605, which are respectively connected to the corresponding first water channel 601, second water channel 602, third water channel 603 and fourth water channel 604. The water channel plate 6 has an installation groove 606, and the rotary valve 8 is located in the installation groove 606 and on the top surface of the four water passage grooves 605. The installation groove 606 has multiple guide protrusions 607, and the first oblique protrusions 802 are slidably disposed in two guide protrusions 607. The first oblique protrusions 802 are in contact with the pressing rotating component.

[0032] The scheme is further optimized. The pressing rotating component includes a drive pin 9 that passes through the mounting groove 606. The top surface of the drive pin 9 is provided with a number of second protrusions 901 at equal intervals around the circumference. The number of second protrusions 901 corresponds to the number of first oblique protrusions 802. The bottom surface of the first oblique protrusion 802 cooperates with the top surface of the second protrusion 901. The second protrusions 901 are slidably disposed in two guide protrusions 607.

[0033] When adjustment is needed, pressing the switch button 3 moves the drive pin 9, causing the second protrusion 901 to push the first inclined protrusion 802 out of the guide protrusion 607. Furthermore, since the mating surfaces of the three components are in inclined contact (see reference...), Figure 4 , Figure 5 At this time, the first inclined protrusion 802 will drive the rotary valve 8 to rotate 90 degrees, which will also cause the opening 801 to rotate 90 degrees, so that the water flows through the corresponding first water channel 601, second water channel 602, third water channel 603 and fourth water channel 604, realizing the conversion of different water spraying modes.
