Embodiment 2
[0043] refer to Figure 5 and Figure 6 , The difference between this embodiment and Embodiment 1 is that: the pressing block 231 is arranged on the pawl 234 and swings in conjunction with the pawl 234 . In this embodiment, the pressing block 231 is replaced from the rotation in the first embodiment to the swing.
[0044]The pressing block 231 is driven to swing when the pawl 234 is driven by the operating member 21 to trigger the electronic switch 24 . Since the ratchet 234 is in the position of engaging with the ratchet 234 of the ratchet wheel 232 when the operating member 21 is not operated, it will only change its position during the operation of the operating member 21, so it has no way to maintain electronic control all the time. The pressing state of the switch 24, for this reason, the electronic switch 24 in this embodiment is a self-locking switch. As long as the electronic switch 24 is touched, the switch state can be switched, and the electronic switch 24 does n...
Embodiment 3
[0047] refer to Figure 7-Figure 9 The difference between this embodiment and Embodiment 1 is that the operating member 21 directly drives the pressing block 26 to swing through the transmission member 22 to drive the electronic switch 24 to open or close, and the pressing block 26 is in the process of swinging Drive the waterway switching member 23 to rotate to switch the waterway.
[0048] In order to realize the swing of the pressing block 26, the pressing block 26 is provided with a sliding groove 261 along the radial direction of the swinging arc, and the operating member 21 is a push-twist; one end of the transmission member 22 is connected with the sliding groove. 261 is slidingly connected, and the other end is linked with the push-twist along the moving direction of the push-twist. When pushed and twisted, one end of the transmission member 22 slides in the slide groove 261 , and then drives the pressing block 26 to swing.
[0049] In order to realize that the press...
Embodiment 4
[0052] refer to Figure 10 The difference between this embodiment and Embodiment 1 is that there are two electronic switches 24, so that when the pressing block 231 is in contact with one of the electronic switches 24, it will be separated from the other electronic switch 24, so that To achieve the purpose of turning on one of the circuits and closing the other circuit, so as to realize the switching of electronic functions.
