The spray gun realizes that the spray water is switched among a plurality of nozzles through the motor rotating reversing valve, thereby realizing the switching of different cleaning water types.

However, in the cleaning process of the spray gun of the traditional intelligent toilet, if the cleaning mode needs to be switched, the spray gun needs to stop the current function first, and after the reversing valve plate is switched into the required function and the residual cold water in the pipeline in the new mode is exhausted, the spray gun stretches out again to spray and clean the human body again. In addition, after the cleaning mode is switched, the pressure and the temperature of the effluent are unstable, so that the user experience is poor.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 to 5, the present application provides a nozzle 10 including a housing 100, a rotating member 200, and a driving device 300. The housing 100 is provided with a water inlet 111, a water inlet channel 112, a regulating hole 113 and a water jet 114, which are sequentially communicated, wherein the water jet 114 is directly communicated with the external environment and is used for jetting water flow. The driving device 300 is disposed in the housing 100 and connected to the rotary member 200. The rotating member 200 is disposed in the adjusting hole 113, and the rotating member 200 is set to rotate along the circumferential direction of the adjusting hole 113 under the driving of the driving device 300, and drives the water flow in the adjusting hole 113 to rotate, so that the water jet 114 can jet different water types.

According to the nozzle 10, when an external water source enters the adjusting hole 113 from the water inlet channel 112, the driving device 300 can drive the rotating member 200 to rotate, and the rotating member 200 can synchronously drive the water flow of the adjusting hole 113 to rotate along the circumferential direction (clockwise or anticlockwise) of the adjusting hole 113 while rotating. Thus, the rotating water stream is dispersed by centrifugal force as it exits the water jet 114.

It can be understood that when the rotation speed of the rotary member 200 is increased and the rotation speed of the water flow in the adjusting hole 113 is increased, the water flow from the water jet 114 is dispersed by the centrifugal force, so that a soft water jet with a large coverage area and a large cone angle can be generated. Conversely, when the rotation speed of the rotary member 200 is reduced and the rotation speed of the water flow in the regulation hole 113 is also reduced, the water flow from the water jet port 114 is dispersed by the centrifugal force, and a water jet type having a small cone angle with a small coverage area is generated. When the driving means 300 does not drive the rotation of the rotary member 200 in the regulation hole 113, the water flow in the regulation hole 113 does not rotate, and thus the water sprayed from the regulation hole is substantially in the shape of a thin cylinder and the coverage area is minimized.

In short, the present application sets the rotating member 200 in the adjusting hole 113, controls whether the rotating member 200 rotates or not through the driving device 300, and controls the rotating speed of the rotating member 200 when rotating through the driving device 300, so as to flexibly adjust the rotating speed of the water flow in the adjusting hole 113, thereby realizing the full-range control that the water type emitted from the water outlet 114 gradually changes from the maximum value to the minimum value of the coverage area, i.e. a single water outlet 114 can emit a plurality of water types. In the process of realizing the mode switching of spraying and washing, the water spray type of the water spray opening 114 can be gradually changed into the small cone angle water spray type from the large cone angle water spray type, and then gradually changed into the thin cylindrical water spray type from the small cone angle water spray type, and the water spray opening 114 can not be cut off, thereby realizing the continuous switching and stepless gradual change of the water spray type and improving the user experience.

Referring to fig. 2, 4, 6, 7 and 8, in one embodiment, the water outlet 114 may be considered as the adjusting hole 113 formed through the housing 100, and the aperture of the adjusting hole 113 gradually shrinks in a direction close to the water outlet 114, i.e. the aperture of the water outlet 114 is larger than that of the adjusting hole 113. The structural arrangement can ensure that the water flow speed of the water flow in the adjusting hole 113 is gradually increased in the process of flowing to the water spraying opening 114, namely, the initial speed of the water flow emitted by the water spraying opening 114 is increased, thereby increasing the range of the water flow.

The shifting piece 240 may also be detachably connected by a snap-fit connection or the like and inserted on the outer circumferential surface of the column 230. The drive means 300 may be a variable frequency electric motor having an output shaft coaxially connected to the cylinder 230.

More specifically, as shown in fig. 5, in some embodiments, the plurality of paddles 240 are each disposed along an axial extension of the cylinder 230. As can be appreciated, such a configuration increases the contact surface of the paddle 240 with water during rotation, so that the paddle can effectively rotate the water stream.
