Title: Water outlet assembly of stool washing device

Description:
FIELD OF THE INVENTION 
     The present invention relates to stool flushing device, and particularly to a water outlet assembly of a stool washing device which has two water outlet portions, and has the functions of angle and transversal adjustments. The water outlet is adjustable to a desired one. 
     BACKGROUND OF THE INVENTION 
     In the prior art stool, only one water outlet is installed for flushing water, however, this kind deign can not flush the stool effectively and completely. Thus in another design, the stool has two outlets with two water tubes, but the two tubes are adjusted individually. Thus the operation is tedious. 
     Furthermore in the prior art, the spraying head is fixed to the stool by screwing or riveting a retaining sheet. The assembly work is difficult and time consumed. In another prior art, the water outlet head is buckled to the stool by using a stool, but in that, the position of the head cannot be adjusted transversally. Thereby all these make difficult in operation and assembly. 
     Therefore, there is an eager demand for a novel one which can improve the defect in the prior art. 
     SUMMARY OF THE INVENTION 
     Accordingly, the primary object of the present invention is to provide a water outlet assembly of a stool washing device which has two water outlet portions, and has the functions of angle and transversal adjustments. The water outlet is adjustable to a desired one. 
     To achieve above objects, the present invention provides a water outlet assembly of a stool washing device which comprises a water outlet head installed with a main portion and a sub-portion; an upper end of the water outlet head having a main inlet and a sub-inlet; the main inlet being communicated to the output hole of the main portion and the sub-inlet being communicated to the outlets of the sub-portion; an adjust portion having two insertion ends at a lower end thereof; each insertion end having a ball like shape; a lower end of each insertion end having a through hole; the insertion ends being engaged to the main inlet and the sub-inlet with the through holes being communicated to the main inlet and the sub-inlet; wherein rotation of the adjust portion will adjust the water output from the outlets. 
     The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

     DETAILED DESCRIPTION OF THE INVENTION 
     In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims. 
     Referring to  FIGS. 1 to 4 , the water outlet assembly of a stool washing device of the present invention is illustrated. The structure of the present invention will be described hereinafter. 
     A water outlet head  10  is a flat block. A flat surface of the water outlet head  10  is installed with a main portion  11  and a sub-portion  12 . In this embodiment, the main portion  11  has an outlet  13  for outputting water and the sub-portion  12  has three outlets  13  for outputting water. However, the numbers of the outlets  13  in the main portion  11  and sub-portion  12  are not confined to this example. 
     An upper end of the water outlet head  10  has a main inlet  14  and a sub-inlet  15 . The main inlet  14  is communicated to the output hole  21  of the main portion  11  and the sub-inlet  15  is communicated to the outlets  13  of the sub-portion  12 . 
     An adjust portion  20  has two insertion ends  21  at a lower end thereof. Each insertion end  21  has a ball like shape (see  FIG. 1-1 ). A lower end of each insertion end  21  has a through hole  22 . The insertion ends  21  are engaged to the main inlet  14  and the sub-inlet  15  with the through holes  22  are communicated to the main inlet  14  and the sub-inlet  15 . Rotation of the adjust portion  20  will adjust the water output from the outlets  13 . 
     The adjust portion  20  has two connection ends  23  at an upper end thereof. The two connection ends  23  are communicated to the two insertion ends  21 . 
     Two water tubes  30  are connected to the two insertion ends  21  of the adjust portion  20 . Water flows from the two water tubes  30  to the two connection ends  23 , the two insertion ends  21 , the main inlet  14  and sub-inlet  15  and then to the outlet  13  of the main portion  11  and the outlets  13  of the sub-portion  12 . 
     The positioning disk  40  is a cover like structure. The positioning disk  40  is installed with a control switch  41 . A pipe set  42  with two pipe lines is installed in the positioning disk  40 . The control switch  41  serves to open and close the water flow of the water tube  30 . The pipe set  42  has an elastic structure. One end of the positioning disk  40  is a combining portion  43  which can be installed to a stool. The positioning disk  40  has a long and slender sliding groove  44  at an end opposite to the combining portion  43 . Two ends of the sliding groove  44  are installed with respective openings  441 . 
     A bottom end of the positioning disk  40  is installed with a cover plate  45  having a shape corresponding to that of the positioning disk  40  so as to seal the positioning disk  40  and thus to confine the elements in the positioning disk  40 . 
     An adjusting block  46  is installed in the sliding groove  44  of the positioning disk  40 . A length of the sliding groove  44  is slightly shorter than that of the sliding groove  44  so as to be received in the sliding groove  44  and is able to slide in the sliding groove  44 . The adjusting block  46  is formed with an embedding groove  461  at a position corresponding to the openings  441 . The pipe set  42  of the positioning disk  40  can be installed to the embedding groove  461  so that the water outlet head  10  is interacted with the adjusting block  46 . 
     In the present invention, the adjustment of the water outlet head  10  is not necessary to detach it as reference to  FIGS. 5 and 6 . 
     In  FIG. 5 , when the water outlet head  10  is moved to left, the water tubes  30  will drive the adjusting block  46  to move along the sliding groove  44  leftwards. The pipe set  42  is flexible and thus it is deform to match the adjustment of the water tube  30 . 
     On the contrary, if the water outlet head  10  is moved rightwards, it will move to a position for flushing water. 
     Referring to  FIGS. 7 and 8 , the angle adjustment of the water outlet head  10  of the present invention is illustrated. When the water outlet head  10  is at a predetermined position in the stool, it has the effect of flushing water. The ball shape insertion ends  21  have the effect of adjusting the angle of the water outlet head  10 . The main portion  11  and sub-inlet  15  make the user can have different flushing effect as desired. 
     The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
