The present invention relates to control over water from a hose and, more particularly, to a nozzle for use with a hose.
In irrigation for example, a hose is connected to a water source such as a faucet at an end and connected to a nozzle at another end. Thus, the nozzle is operable to control water from the faucet through the hose.
A conventional nozzle includes a mechanism to control the flow rate and another mechanism to control splash patterns. Basically, the operation of the first mechanism is independent of the operation of the second mechanism. The first mechanism includes a number of elements. The second mechanism includes another amount of element. Hence, there are problems with this conventional nozzle.
Firstly, it is structurally complicated for including a large amount of elements. This large amount of elements inevitably increases the cost of the conventional nozzle regarding the production of the elements and regarding the assembly.
Secondly, it is bulky for including the large amount of elements. The large size renders it difficult to carry and store the conventional nozzle.
Thirdly, the operation of the conventional nozzle is complicated because a trigger is operated to control the flow rate and a switch is operated to select from the splash patterns. It requires skills from a user to handle this conventional nozzle.
Fourthly, the entire conventional nozzle has to be disassembled even though only the first or second mechanisms is out of order. The maintenance of this conventional nozzle is troublesome and hence expensive.
The present invention is therefore intended to obviate or at least alleviate the problems encountered in the prior art.
It is the primary objective of the present invention to provide an inexpensive, compact, easy-to-use and easy-to-maintain nozzle.
To achieve the foregoing objective, the nozzle includes a shell, a splashing plate, a valve and a switch. The splashing plate is connected to the shell. The valve is movably inserted in the shell. The switch is connected to the shell and the valve both. The switch is operable to control the flow rate and splash patterns.
Other objectives, advantages and features of the present invention will be apparent from the following description referring to the attached drawings.
The present invention will be described via detailed illustration of the preferred embodiment referring to the drawings wherein:

The rings 443 and 444, which are always in contact with the wall of the section 133 of the axial channel 13, close the annular groove 433. The ring 442, which are always in contact with the wall of the section 132 of the axial channel 13, closes the annular groove 432 on a side but allows the annular groove 432 to communicate with the conical aperture 31 of the splashing plate 30 through the sections 132 and 131 of the axial channel 13.
Thus, water goes from the hose H into the inlet 42, the first group of outlets 451 and the sections 132 and 131 of the axial channel 13. Finally, the water goes out of the conical aperture 31 of the splashing plate 30 as conical splash.
Referring to
The rings 443 and 444, which are always in contact with the wall of the axial channel 13, close the annular groove 433. The ring 442, which is always in contact with the wall of the axial channel 13, closes the annular groove 432 on a side but allows the annular groove 432 to communicate with the conical aperture 31 of the splashing plate 30 through the gap.
Thus, water goes from the hose H into the inlet 42, the first group of outlets 451, the annular groove 432, the axial channel 13 and the annular groove 431 and the gap. Finally, the water goes out of the conical aperture 31 in a water jet.
