[0002] Existing smart toilets generally have the functions of butt washing and women washing. With the development of smart toilet manufacturing technology, the water type of the spray gun of the smart toilet is generally changed by adding an air pump or a pulse pump to introduce air into the spray gun, and by controlling the opening and closing of the air pump or the pulse pump, the water is changed from a continuous water column type to an intermittent pulse water type, thereby achieving a change in water type. The use of an air pump or a pulse pump will occupy additional internal space of the smart toilet, and because the ventilation pipe of the air pump or the pulse pump is connected to the water circuit of the spray gun, the water pressure in the water circuit will flow back to the inside of the air pump or the pulse pump through the ventilation pipe, causing the internal pressure to be pressurized, which is easy to cause damage to the pump body.

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0022] like Figure 1-Figure 3 As shown, a specific embodiment of the utility model provides a spray head, including a spray head body 1, a water outlet 2 and a vibration plate 3. A water inlet 4 is provided on one side of the spray head body 1, and a receiving chamber 11 connected to the water inlet 4 is provided inside; the water outlet 2 is provided in the receiving chamber 11, and can move up and down relative to the receiving chamber 11; the water outlet 2 is provided with a water outlet chamber 21 connected to the receiving chamber 11, and the water outlet chamber 21 is also connected to a water outlet hole 22 located on the surface of the water outlet 2; the water outlet 2 extends from the bottom of the spray head body 1 and is connected to the vibration plate 3, and the vibration plate 3 is used to drive the water outlet 2 to vibrate up and down relative to the spray head body 1. The vibration plate 3 and the spray head body 1 are relatively fixed by an additional shell.

[0023] By adopting the above embodiment, the water outlet 2 is driven to vibrate up and down by the vibration plate 3, so that the water outlet 2 sprays out intermittent pulse water columns, which improves the cleanliness of flushing, and can also improve the user experience and meet the needs of different users. In addition, the vibration plate 3 can be a piezoelectric ceramic sheet. The piezoelectric ceramic sheet is small in size and does not directly contact the water channel. It has the advantages of occupying a small space and not being easily damaged. By controlling and adjusting the voltage frequency passed into the piezoelectric ceramic sheet, the vibration frequency of the piezoelectric ceramic sheet can be adjusted, thereby obtaining pulse water columns of different frequencies, providing more personalized functions, and meeting the cleaning needs of different users.

[0024] Specifically, the water outlet 2 includes a butt wash water outlet 2a and a women's wash water outlet 2b, and the water inlet 4 includes a butt wash water inlet 4a and a women's wash water inlet 4b; the butt wash water outlet 2a and the women's wash water outlet 2b are respectively arranged in the independent accommodating cavity 11. The butt wash water outlet 2a is provided with a butt wash water outlet hole 22a, and the women's wash water outlet 2b is provided with a women's wash water outlet hole 22b, and the diameter of the butt wash water outlet hole 22a is greater than the diameter of the women's wash water outlet hole 22b.

[0025] It should be noted that the hip wash water outlet 2a is used to realize the hip wash function, while the feminine wash water outlet 2b is used to realize the feminine wash function. Generally speaking, hip wash requires a larger water flow, so the diameter of the hip wash water outlet 22a is made larger than the diameter of the feminine wash water outlet 22b, and a water column with a larger diameter can be sprayed through the hip wash water outlet 2a to realize the functional change of hip wash and feminine wash.

[0026] Preferably, the number of the women's wash water outlet holes 22b is greater than the number of the hip wash water outlet holes 22a. In this embodiment, there is one hip wash water outlet hole 22a and four women's wash water outlet holes 22b. The four women's wash water outlet holes 22b can form a larger washing surface, and the force is relatively gentle, meeting the needs of women's wash. Of course, the number of women's wash water outlet holes 22b can also be set to 2, 3 or more than 4 according to needs.

[0027] Combination Figure 4 and Figure 5 As shown, for ease of assembly, a nozzle base plate 5 is provided at the bottom of the nozzle body 1, and a sealing convex strip 51 is provided at the edge of the nozzle base plate 5 corresponding to the accommodating cavity 11, and a sealing groove 12 is provided at the bottom of the nozzle body 1; the nozzle base plate 5 is provided with a nozzle limiting hole 52 that allows the water outlet 2 to pass through. During installation, glue can be applied to the sealing groove 12 first, and then the sealing convex strip 51 of the nozzle base plate 5 is installed into the sealing groove 12 to form a complete accommodating cavity 11. A sealing ring 6 is provided on the side of the water outlet 2. The sealing ring 6 abuts against the surface of the accommodating cavity 11 to ensure that the water inlet 4 is sealed and connected with the water outlet cavity 21 of the water outlet 2 through the accommodating cavity 11.

[0028] The nozzle body 1 is provided with a step surface 13 at the top of the accommodating chamber 11, and the water outlet 2 is provided with a limiting top surface 23 that cooperates with the step surface 13, and there is a 0.5-1mm gap between the limiting top surface 23 and the step surface 13. The step surface 13 is provided with an assembly hole 14, and the assembly hole 14 allows the top end 24 of the water outlet 2 provided with the water outlet hole 22 to extend therefrom; and the step surface 13 cooperates with the limiting top surface 23 to limit the maximum stroke of the water outlet 2. When the water outlet 2 is driven by the vibration plate 3 to move up and down in the accommodating chamber 11, the water in the water outlet chamber 21 is pushed outward at the same frequency, forming a pulsed water flow that sprays outward.

[0029] Finally, the specific embodiment of the utility model also provides a spray gun, which is provided with the spray head as described above. The spray gun provided in this embodiment has a compact structure of the spray head, occupies a small space, and can provide a pulsed outward water flow, thereby providing more personalized functions to meet the cleaning needs of different users.

[0030] The above is a preferred embodiment of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
