Since the pawl 13 is always engaged with the ratchet 10 and the pawl 13 has elasticity, the pawl 13 can change a position engaged with the ratchet 10 when the ratchet 10 rotates. However, if the ratchet 10 rotates in the opposite direction, the pawl 13 collides with the external tooth surface 10b1, thereby preventing the ratchet 10 from reversing, ensuring that the ratchet 10 can only rotate forward but not reverse, and avoiding the switching failure.
Further, as shown in fig. 2 and 12, a seal ring 14 for sealing water is provided on the inner side wall of the lower body 1, and the turntable 4 is hermetically connected to the lower body 1 via the seal ring 14, and the seal ring 14 has a longitudinal cross-sectional shape with a wide middle and narrow ends. The upper end and the lower end of the sealing ring 14 are narrower than the middle part, namely the upper end and the lower end are symmetrically arranged, so that the contact area between the rotary disk 4 and the sealing ring 14 is reduced, the friction force is reduced, the switching hand feeling is lighter, and the operation is easy. Meanwhile, the upper end and the lower end are narrow, so that convenience is brought to installation, and the installation direction does not need to be identified.
Preferably, as shown in fig. 10 and 11, the upper opening edge of the water guiding hole 4a is provided with a first rounded corner 4a1, and the lower opening edge is provided with a second rounded corner 4a2. The invention utilizes the coanda effect, and leads the water on the upper surface of the rotary disk 4 to the water guide hole 4a through the first round angle 4a1, thereby realizing quick water outlet. The second rounded corners 4a2 can prevent the sealing ring 14 from being damaged by scraping the sealing ring 14 at the edge of the water guide hole 4a in the rotating process of the turntable 4, so that the water sealing effect is weakened.
Correspondingly, as shown in fig. 15-16, the invention also discloses a shower head, which comprises a shell 100 and the water outlet switching device arranged in the shell 100. The specific structure of the water outlet switching device is as above, and will not be described here again. Wherein, the distance between the top end of the reinforcing rib ring 1f and the inner wall of the housing 100 is 1mm, and the distance between the top end of the rotating shaft 11 and the inner wall of the housing 100 is 2mm.
The working principle of the water outlet switching device of the invention is as follows: the driving member 5 is manually pressed, the driving member 5 pushes the crank 6, the crank 6 pushes the transmission rod 7 to move towards the ratchet 10, and the pawl 9 moves towards the ratchet 10. At the same time, the pawl 9 automatically engages with the ratchet 10 under the action of the tightly driving mechanism, so that the pawl 9 drives the ratchet 10 to rotate. The ratchet wheel 10 drives the turntable 4 to rotate through the rotating shaft 11, so that the water guide holes 4a are connected with different water outlets 2a, and water outlet switching is realized. The driving rod 7 is reset under the action of the first spring 8 by loosening the hand, the pawl 9, the crank 6 and the driving piece 5 are reset at the same time, and the ratchet wheel 10 is not driven by the pawl 9 under the action of the stopping claw 13. Thus, the next switching operation can be performed.
The implementation of the invention has the following beneficial effects:
the invention sets the strengthening component on the water outlet main body, the strengthening component can increase the strength of the water outlet main body, and avoid the deformation of the water outlet main body in the environment of long-term high temperature and high pressure, thereby avoiding the situation that the switching component pawl 9 and ratchet 10 arranged on the water outlet main body are blocked with the shell 100 and can not realize the switching. Wherein, the strengthening subassembly includes strengthening rib ring 1f and strengthening rib strip 1h, and when the play water main part warp and upwards bulge, the strengthening rib ring 1f can touch the inner wall of casing 100, plays spacing effect to the play water main part, and the height that highly is greater than actuating mechanism and step by step mechanism of strengthening rib ring 1f simultaneously makes actuating mechanism and step by step mechanism can not with casing 100 jamming, guarantees actuating mechanism and step by step mechanism normal work. The reinforcing rib blocks 1g can support the reinforcing rib ring 1f and strengthen the strength of the reinforcing rib ring 1 f. The strength of the water outlet main body can be enhanced by the reinforcing ribs 1h, so that the water outlet main body is not easy to deform.
In addition, the invention also provides a tight driving mechanism, so that the pawl 9 and the ratchet wheel 10 are not easy to separate in the water outlet switching process, the pawl 9 can effectively and reliably drive the ratchet wheel 10 to rotate, the operation is reliable, and the switching failure is effectively prevented. Specifically, the tight drive mechanism comprises a tight connection assembly and a tight drive connection assembly, the tight connection assembly pushes the pawl 9 to the ratchet 10, the pawl 9 is guaranteed to move to one side of the ratchet 10, the pawl 9 is not separated from the ratchet 10, and switching failure is prevented. The driving assembly enables the pawl 9 to be automatically meshed with the ratchet wheel 10, so that the connection reliability of the pawl 9 and the ratchet wheel 10 is further ensured, and the reliability of operation switching is further ensured.
In conclusion, the water outlet switching device and the shower head are compact and firm in structure and reliable in operation, and clamping stagnation and switching failure are effectively prevented.
The foregoing is a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention and are intended to be comprehended within the scope of the present invention.
