Detailed Description

The invention will be further described in the following with reference to specific embodiments thereof, with reference to the accompanying drawings, in which fig. 1-3:

a change-over valve for a closestool comprises an upper shell 1 with a lower opening 10 and a water inlet pipe 11, wherein a water inlet cavity 12 is formed in the upper shell 1, the lower end of the upper shell 1 is fixedly connected with a base 2 with an upper opening 20, a water outlet cavity 21 is formed in the base 2, the water outlet cavity 21 forms a first water cavity 210 and a second water cavity 211 through a partition plate 3, the lower end of the first water cavity 210 is connected with a first water pipe 22, the lower end of the second water cavity 211 is connected with a second water pipe 23, the upper end of the base 2 is covered with a ceramic bottom plate 4, the ceramic bottom plate 4 is provided with a first water outlet 40 communicated with the first water cavity 210 and a second water outlet 41 communicated with the second water cavity 211, a ceramic cover plate 5 is covered above the ceramic bottom plate 4, the water inlet hole 50 is formed on the ceramic cover plate 5, the upper end of the ceramic cover plate 5 is inserted with a driven shaft 6, a mounting seat 13 for mounting the driven shaft 6 is formed at the top in the upper shell 1, the upper end of the upper shell 1 is provided with a driving motor 7, a driving shaft of the driving motor 7 penetrates through the top of the upper shell 1 and is fixedly connected with the driven shaft 6 in the mounting seat 13, and when the driving motor 7 drives the driven shaft 6 to rotate, the water inlet hole 50 is communicated with the second water outlet hole 41 and slides to the state that the water inlet hole 50 is communicated with the first water outlet hole 40 or the water inlet hole 50 is communicated with the first water outlet hole 40 and slides to the state that the water inlet hole 50 is communicated with the second water outlet hole 41.

The closestool is washed by water and is had two kinds of circumstances, for 22 play water of first water pipe and 23 play water of second water pipe, realize two kinds of above-mentioned play water circumstances and do, driven shaft 6 is because of driving motor 7, driven shaft 6 rotates for the ceramic cover plate rotates, different apopores are aimed at to inlet opening 50 on the ceramic cover plate 4 after the rotation, aim at first apopore 40 and realize 22 play water of first water pipe, aim at the play water that second apopore 41 realized second water pipe 23.

Preferably, the outer edge of the ceramic base plate 4 is formed with a clamping portion 42, and the inner side wall of the upper shell 1 is formed with a clamping groove 14 matched with the clamping portion 42. By utilizing the structure, the ceramic gasket 4 is convenient to fix and is not easy to slide when water flows out.

It is worth mentioning that a gasket is arranged between the ceramic bottom plate 4 and the upper end of the base 2, and due to the problem of ceramic material, the sealing performance between the ceramic bottom plate 4 and the base 2 is poor, and the sealing performance of the joint between the ceramic bottom plate 4 and the base 2 is enhanced by the setting of the gasket.

Preferably, a diversion trench 51 is formed between the outer wall of the ceramic cover plate 5 and the inner side wall of the upper shell 1.

Preferably, the water inlet pipe 11 is obliquely inserted into the upper shell 1.

Ceramic cover 5 is in often pivoted state, along with long-time rotation, impurity in aquatic adsorbs easily between ceramic cover 5 and ceramic film 4, thereby influence sealing performance, and guiding gutter 51 that forms between the lateral wall piles up silt or other impurity with guiding gutter 51 in easily, the inlet tube 11 rivers that again sets up through the slope erode the guiding gutter 51 with impurity rushing out, and along with rivers gush into inlet opening 50 and rush out, its main objective of foretell structure is for avoiding piling up of impurity, thereby the leakproofness of indirect protection valve, thereby prolong its life.

Preferably, the partition plate 3 is L-shaped, the outlet cavity 21 forms the first water cavity 210 and the second water cavity 211 with a cavity ratio of 1:3 through the partition plate 3, the number of the second water outlet holes 41 is two, the first water outlet hole 40 and the second water outlet hole 41 are in a 90-degree fan shape with the same shape, the two second water outlet holes 41 are respectively arranged at two sides of the first water outlet hole 40, the number of the water inlet holes 50 is two, and the two water inlet holes 50 are oppositely arranged above the two second water outlet holes 41.

The retainer ring 130 and the base 2 are integrally formed, and the proportion of the first water cavity 210 to the second water cavity 211 is selected to be 1:3 consider that different bath positions need different bath dynamics, so it is not saying that first water cavity 210 and second water cavity 211 set up the communicating volume size to spout 131 occupies its 1/4 in retaining ring 130 position, and the 90 rotation contained angle that forms lets driving motor rotation range less, makes the friction scope between ceramic cover plate 5 and the ceramic film 4 less, reduces the ceramic wafer loss, strengthens the leakproofness more.

Preferably, the outer wall of the driven shaft 6 is sleeved with a plurality of sealing rings 61. The sealing performance between the driven shaft and the inner wall of the mounting seat is enhanced.

The working principle is as follows:

the utility model discloses utilize driving motor to drive the rotation of ceramic cover plate to the apopore of realizing following on the different ceramic films goes out water, and utilizes the guiding gutter to place piling up of aquatic impurity, thereby strengthens the leakproofness more, makes this change-over valve life-span longer, and is more durable.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
