Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When one element is referred to as being "fixedly attached" to another element, it can be fixedly attached by welding, bolting, gluing, or the like.
Referring to fig. 1-3, in a preferred embodiment of the present invention, a rotary sealing device is disclosed, which includes a fixing base 1, a nozzle tube 2, a sealing sleeve 3, a first sealing ring 4 and a nozzle 5; one end of the fixed seat 1 is provided with a water inlet; one end of the spray pipe 2 is rotatably arranged in the fixed seat 1, and a pipeline of the spray pipe 2 is communicated with the water inlet; the sealing sleeve 3 is rotatably arranged on the outer side of the fixed seat 1 and is fixed on the outer side of the spray pipe 2; the first sealing ring 4 is rotatably sleeved on the outer side of the spray pipe 2 and is arranged between the fixed seat 1 and the sealing sleeve 3; the nozzle 5 is disposed at one side of the spout 2 and communicates with the duct of the spout 2.
