Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of dialing shower. BACKGROUND

[0002] In the long-term use process, the inside of the water spray hole of the shower is easily attached by scale, resulting in small water output, poor user experience and other problems. The common cleaning method is to use a needle object to prick and push the scale out of the water spray hole. However, the process of pricking from the outside to the inside can easily bring the scale back into the water outlet cavity of the shower. In subsequent use, the scale will still flow into the water spray hole. If the removal method is from the inside to the outside, the shower structure needs to be disassembled as a whole, which undoubtedly increases the removal difficulty. SUMMARY

[0044] The structure of each component of the utility model is described below.

[0045] As Figure 4 , Figure 9 and Figure 10 shown, the number of actuating grooves 221 on the top surface of actuating plate 22 is four as an example, and four actuating grooves 221 are arranged in a rectangular array on actuating plate 22, and the number of actuating grooves 221 opened on driving frame 40 corresponds to and is arranged in position with sliding block 42;Such design can improve the stability of the movement of needle plate 23, so that the overall structure has high structural strength.

The drive frame 40 has a drive groove 41 with an opening facing downward on both sides at the tail end, which allows the push blocks 321 to slide up and down. When the actuating tube 32 is slidably moved along the axial direction of the connecting tube 33, the push blocks 321 push the groove wall of the drive groove 41 to drive the drive frame 40 to move forward as a whole. During this process, the sliding block 42 on the drive frame 40 moves forward synchronously and slides from point C to point B on the actuation slope 222. The actuation plate 22 is subjected to the downward pressure of the sliding block 42 and synchronously drives the needle plate 23 to move longitudinally downward, so that the cleaning needle 231 is inserted downward into the water spray hole 241 and pushes out the dirt in the water spray hole 241.

[0047] like Figures 4-7 As shown, the upper surface of the water supply chamber plate 21 has several limiting hooks 211 for preventing the drive frame 40 from disengaging from the water supply chamber plate 21. The actuating plate 22 has clearance holes 223 for the limiting hooks 211 to pass through. The actuating plate 22 and the needle plate 23 are fixed together by bolts 50. There are four bolts 50 arranged in a rectangular array. The actuating plate 22 has through holes 224 for the bolts 50 to pass through. The needle plate 23... A threaded post 232 for bolt 50 to be screwed is fixed on the top surface. A boss 212 corresponding to bolt 50 is provided on the water supply chamber plate 21. A sliding hole 2121 for the threaded post 232 to slide up and down is provided on the boss 212. A return spring 213 for providing an upward movement tendency for the needle plate 23 and the actuating plate 22 is sleeved on the outer periphery of the boss 212. One end of the return spring 213 contacts the bottom surface of the actuating plate 22, and the other end contacts the top surface of the water supply chamber plate 21.

[0049] It should be noted that the first water outlet hole 214 and the second water outlet hole 215 correspond to different water outlet modes, when the first water outlet cavity 201 resumes water supply, water flows out of the first water outlet hole 214 and flows out of the water outlet hole 241 on the water outlet panel 24 to complete the water outlet of the shower; and when the second water outlet cavity 202 resumes water supply, water directly flows out of the second water outlet hole 215, and users can select the water outlet mode corresponding to the second water outlet mode according to actual use requirements.

[0050] As shown in Figure 2 and Figure 3 The push pipe 32 further includes an extension plate 324 fixedly arranged on the peripheral surface of the pipe body 322 and extending forward, and a mounting bracket 325 in the shape of T is buckled to the front end of the extension plate 324, and two pushing blocks 321 are fixedly arranged on the left and right sides of the mounting bracket 325.

In this way, the sealing performance of the push pipe 32 during movement can be improved, and the situation of liquid leakage can be avoided. The shell 10 is buckled by half, and a knob 326 is fixedly connected to the extension plate 324, and a strip-shaped hole 11 is formed on the shell 10 for sliding cooperation of the knob 326.

[0051] As shown in Figure 2As shown, a spring pin 311 is arranged at the lower end of the outer wall of the water inlet pipe 31, and the poking pipe 32 further comprises a fixing plate 327 fixed to the outer wall of the pipe body 322 and extending rearward, and the fixing plate 327 is provided with first positioning holes 3271 spaced apart thereon and matched with the spring pin 311 when the shower head is in the first water outlet state, and second positioning holes 3272 matched with the spring pin 311 when the shower head is in the second water outlet state; in this way, the locking effect of the poking pipe 32 can be achieved, and when the spring pin 311 is matched with the positioning holes, a crisp "click" sound will be emitted, thereby achieving the prompting effect.
