Detailed ways

The descriptions of the front end and the back end in the present invention can be described in conjunction with Fig. 1 , the front end is on the bottom and the back end is on the top. In the present invention, the purpose of using "first" and "second" is to differentiate and describe structures with the same function, and should not be understood as indicating or implying a difference in relative importance or implicitly indicating the number of differentiated technical features. Therefore, the use of "first" does not necessarily include the corresponding "second" feature.

The present invention firstly provides a spraying device for sanitary ware, which is generally used for cleaning and decontamination. Taking the spraying device upright as an example, that is, the state shown in FIG. 1 , the motor 3 is located above the movable part 2 , and the present invention will be described in detail in conjunction with specific embodiments.

Embodiment one:

As shown in Figures 1 to 6, a spraying device for sanitary ware includes a fixed part 1, a movable part 2, a fluid channel and a motor 3, and the fixed part 1 is fixed on the sanitary ware. What kind of sanitary ware will be described later In the detailed description of the embodiment, the movable part 2 is arranged in the fixed part 1 and is flexibly connected with the fixed part, the motor 3 is fixed on the fixed part 1, and the motor 3 can also be fixed on the sanitary ware according to the actual situation, the movable part 2 and the motor 3’s output shaft transmission connection, the movable part 2 is driven by the motor 3 to rotate relative to the fixed part 1, in this embodiment, the fluid channel includes a first channel and a second channel, the first channel is located in the fixed part 1, and the second channel Set in the movable part 2. Specifically, the first channel has a first inlet 11 and a first outlet 12, the second channel has a second inlet 21 and a second outlet 22, and the second inlet 21 corresponds to and communicates with the first outlet 12, which can be understood as a cleaning agent solution After flowing out of the first outlet 12, it automatically flows into the second inlet 21, the first inlet 11 is used as the inlet of the fluid channel, and the second outlet 22 is used as the outlet of the fluid channel.

On the one hand, according to actual needs, the motor 3 can be used to control the movable part 2 to rotate at a constant speed or at a variable speed, and to control the rotation angle of the movable part 2, so that the movable part 2 can rotate forward and reverse within a certain angle, or it can always be kept The movable part 2 rotates in the same direction. On the other hand, since the active part 2 does not need the action of the detergent solution to rotate the movable part, the detergent solution does not need excessive pressure. After the detergent solution passes through the movable part 2 There will not be too much turbulent flow, so that the detergent solution flows relatively smoothly in the fluid channel, which is more conducive to uniform spraying. Most cleansers will have a certain degree of foam after dissolving, and the foam can not withstand a slightly larger pressure. Like the technical scheme mentioned in the background technology, it cannot adapt to chemical preparations with more foam. In the present invention, due to the foam flow The pressure received during the process is small, so the foam is not easy to break, the effect of foam spraying is still very good, and the integrity of the foam can be maintained, so that the cleaning effect of the foam is also improved.

Because the detergent solution can always produce foam, in order to make the foam formed by the detergent solution more delicate, a plurality of first ribs 26 are arranged in the second channel, and the first ribs 26 are distributed around the axis of rotation of the movable part. A communication opening 27 for fluid to pass is formed between two adjacent first ribs 26 . Since the movable part 2 is in a rotating state during work, the first tendon 26 will follow the rotation of the movable part 2, and will stir the cleaning agent solution passing through the flow port 27, making the big foam into a small foam, and the flow port 27 The size can be controlled, and the function similar to that of a filter is formed during the rotation process, which also turns the large foam into a small foam, so that the foam can be refined, and the foam can be sprayed more easily, thereby improving the cleaning ability of the detergent solution. There are many ways to arrange the first ribs 26 , which will be described below in conjunction with the specific structure of this embodiment.

In this embodiment, the fixed part 1 has a first cavity 100 inside, and the movable part 2 protrudes into the first cavity 100 for fitting and installation, so the movable part 2 is driven by the motor 3 to rotate along the inner side wall of the first cavity 100 . The front and rear ends of the first cavity 100 pass through, the movable part 2 extends from the rear end of the first cavity 100 and protrudes from the front end of the first cavity 100, and the second outlet 22 is located at the front end of the movable part 2 and is located at The outside of the fixture 1.

In order to enable the detergent solution to cover a certain area after spraying from the second outlet 22, it is required that the axis of the second outlet 22 is not parallel to the rotation axis of the movable part 2, and the two may be in the same plane or may not be in the same plane , as long as the cleaning agent solution can be sprayed from the second outlet 22 instead of spraying along the direction of the rotation axis of the movable member 2, but spraying around, the cleaning solution can be sprayed out to cover a certain area. Under the condition that the cleaning agent solution delivery pressure is constant, the angle α between the axis of the second outlet 22 and the rotation axis of the movable part 2 will affect the radius of the cleaning agent solution injection, and α can generally be 5° to 90°. °, such as 5°, 30°, 45°, 60°, 75° or 90°, etc. Of course, in some sanitary appliances, the sprayed cleaning agent solution does not need to form a covering effect, only the cleaning agent solution needs to be sprayed evenly, so the axis of the second outlet 22 can also be parallel to the rotation axis of the movable part 2 .

The structure of the fixing part 1 is seen in conjunction with FIGS. 1 to 4 .

The side wall body of the fixture 1 has a thick-walled portion 13, and a buffer cavity 130 is provided inside the thick-walled portion 13.

The first outlet 12 is arranged on the inner side wall of the first cavity 100, and the first outlet 12 is correspondingly located at the bottom of the buffer chamber 130. The width of the first outlet 12 is consistent with the width of the buffer chamber 130, so that the cleaning agent solution is discharged from the buffer chamber 130. , to avoid the residual detergent solution in the buffer cavity 130 .

The axis of the first inlet 11 is not on the same plane as the axis of rotation of the movable part 2. As shown in Figure 3, the dotted line shows the symmetrical plane M where the axis of rotation of the movable part 2 is located. It can be seen that the first inlet 11 is set The connection head 14 is offset relative to the plane of symmetry M. It can be understood that the first inlet 11 and the first outlet 12 are located on one side of the plane of symmetry M, so that the detergent solution enters the second channel from one side of the plane of symmetry M, which Associated with the rotation of the motor 3, it can facilitate the flow of the detergent solution into the second channel without requiring a large delivery pressure. Associated with the rotation of the motor 3, for example, the motor 3 drives the movable part 2 to rotate, enabling the first outlet 12 A certain degree of negative pressure is formed, and the detergent solution in the buffer chamber 130 can automatically replenish to the second channel under the action of negative pressure, so the delivery pressure of the detergent solution can be appropriately reduced.

Considering the rotation of the movable part 2 and the sealing fit between the movable part 2 and the inner wall of the fixed part 1, the cross section of the inner side wall of the fixed part is preferably a circle, and the cross section of the outer side wall of the movable part 2 is also preferably a circle.
