The mounting parts 34a, 34b are corresponding to the mounting parts 14a,14b of the first housing 1 for clipping the valve assembly 5 therebetween. The shape of the mounting parts 34a, 34b and the mounting parts 14a,14b is not limited and is able to be modified according to the shape of the valve assembly 5. A plurality of second assembly holes 311 corresponding to the first assembly hole 13 of the first housing 1 is disposed on the inner surface 31b for being threaded a screw (not shown in figure) therein and assembling with the corresponding first housing 1 and the second housing 3 so as to form a second space B, as shown in FIG. 7.
The first fasteners 212a, 212b and the second fasteners 213a, 213b on the first cover 21 of the display module 2 are hidden by the label plate 27 attached over the panel 21a. That means the label plate 27 covers the first fasteners 212a, 212b and the second fasteners 213a, 213b. Thus after the display module 2 being assembled into the frame 11 of the first housing, the first fasteners 212a, 212b and the second fasteners 213a, 213b are not exposed and unable to be seen.
Refer to FIG. 7, one end of the first fasteners 212a, 212b and of the second fasteners 213a, 213b is disposed with hooks 212a′, 213a′respectively. The hooks 212a′, 213a′ feature on the inverted type. The hooks 212a′, 213a′ are disposed in opposite directions. The first fasteners 212a, 212b and the second fasteners 213a, 213b are arranged at the wall 211a of the first cover 21 symmetrically, without projecting out of the wall 211a. After being mounted into the frame 11 of the first housing 1, the display module 2 is locked with the first assembly concaves 11a, 11b and the second assembly concaves 11c, 11d of the frame 11 by the hooks 212a′, 213a′. 
The above components are assembled by the following steps:
(i) First the second cover 24 of the display module 2 is aligned to an inner edge of the walls 211a, 211b of the first cover 1, as shown in FIG. 4 and a screw is passed through each fourth assembly holes 244 and threaded into the third assembly hole 214 so as to connect the first cover 21 and the second cover 24 closely. This is the first step. Before connecting the first cover 21 and the second cover 24, the display panel, the input member 22, and the circuit board 26 are mounted into the first cover 21.
(ii) Then the first fasteners 212a, 212b and the second fasteners 213a, 213b of the display module 2 are corresponding to and locked with the inner walls of the first assembly concaves 11a, 11b and the second assembly concaves 11c, 11d of the first housing 1 at the angle below the horizontal. The stopping part 215 of the first cover 21 is against the periphery 111 of the first housing 1. Thereby the display module 2 is connected to the first housing 1 and the display module 2 is unable to be detached from the outside. This is a second step.
(iii) Next, the valve assembly 5 is positioned at the mounting parts 14a,14b of the first housing 1 and the ribs 41 of the side plates 4a, 4b are inserted the first guiding slots 12a, 12b, 12c, 12d and the second guiding slots 121a, 121b, 121c, 121d of the first housing 1 for positioning. This is the third step.
(iv) The mounting parts 34a,34b of the second housing 3 is aligned to the valve assembly 5 and the second assembly holes 311 are corresponding to the first assembly holes 13 of the first housing 1. Then screws are threaded into the second assembly holes 311 and the first assembly holes 13 so as to connect the first housing 1 to the second housing 3. At last, the front end 25a of the battery box 25 is mounted into the second end 243b at the angle above the horizontal. Thus the assembling of the water timer of the present invention is completed. The assembled water timer is shown in FIG. 8.
Furthermore, the periphery of the first housing 1 and the periphery of the second housing 3 are disposed with at least one male buckle and at least one female buckle. The male buckle is a rib 15 projecting from the periphery while the female buckle is a hollow part 34 corresponding to the rib 15. Thereby the first housing 1 and the second housing 3 are assembled with and positioned by each other.
In summary, the present invention has following advantages:
1. Due to the locked/limited design, the assembling of the water timer is easy and quick during production processes.
2. The battery box 25 is mounted in the rectangular column 243 at the angle below the horizontal. The inclined arrangement of the battery box 25 enables smooth movement of the rectangular column 243 while replacing the battery. Moreover, when there is water flowing into the water timer, the water flows downward along the rectangular column 243. Such design prevents water from flowing into the battery box 25.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
