Detailed Description

The present invention will now be further described with reference to the accompanying drawings and specific embodiments. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 4, the technical solution adopted by the present embodiment is:

a water splashing device with a sealing function comprises a water splashing disc 35 with the water splashing function and a spraying plug 3 which can be used for blocking or opening a water outlet 84 of a water splashing device 81 under the action of external force and can realize automatic centering with the water outlet 84 of the water splashing device 81 when being assembled, wherein the upper end face of the water splashing disc 35 is fixedly connected with the lower end face of the spraying plug 3, a sealing member 33 for sealing the water outlet 84 of the water splashing device is further arranged on the spraying plug 3, the water splashing device further comprises two guide rods 36, the lower end faces of the guide rods 36 are fixedly connected with the water splashing disc 35 and are arranged on the water splashing disc 35 at an angle of 180 degrees in the circumferential direction of the water splashing disc 35, ten water splashing blades 34 for enlarging a water splashing area are arranged at equal angle intervals in the circumferential direction of the edge of the water splashing disc 35, the two guide rods 39 are fixedly connected with the lower end faces of the guide rods 36, the guide rods 36 not only can play a role of guiding sliding, but also can be convenient for installing the water splashing device at a proper position to block or open the water splashing device 84, the upper end of the guide rods 36 can limit the water splashing device 38 to enable the water splashing device to slide to move to a maximum position after the water splashing device is arranged at the water splashing device 81.

The spraying plug 3 comprises a round table 31 passing through the water outlet 84 of the water spraying device 81 and extending into the internal communication channel 85 of the water spraying device 81 for blocking or opening the internal communication channel 85, the lower bottom surface of the round table 31 is matched with the water outlet 84 of the water spraying device 81 to realize the automatic centering function of the round table 31 and the internal communication channel 85 of the water spraying device 81, the lower bottom surface of the round table 31 is provided with the connecting column 32 of the sealing element 33, the lower bottom surface of the connecting column 32 is provided with the abutting block 37 abutting against the radial end surface of the water outlet 84 of the water spraying device 81, and the lower end surface of the abutting block 37 is fixedly connected with the upper end surface of the water spraying disc 35.

The inclined plane 24 of the circular truncated cone 31 is favorable for the spraying plug 3 to smoothly enter the internal communication channel 85 of the water spraying device 81, when the lower bottom surface 25 of the circular truncated cone 31 is matched with the water outlet 84 of the water spraying device 81 to realize automatic centering, the axis 10 of the circular truncated cone 31 is superposed with the axis 7 of the internal communication channel 85 of the water spraying device 81, and when the circular truncated cone 31 is continuously pushed tightly, the sealing element 33 on the connecting column 32 can be propped against the end surface of the water outlet 84 of the water spraying device 81 by taking the axis 10 of the circular truncated cone 31 as the center, so that the water outlet 84 of the water spraying device 81 is more effectively sealed.
