The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 2 and 3, the present embodiment provides a switching mechanism, which includes a water pipe 110, a switching pipe 130, a switching base 120, a water dividing head 140, and a push rod 150. The water passage pipe 110 is provided with a water passage 111 therein, the switching pipe 130 is provided with a switching passage 131 therein, and the push rod 150 is disposed on the switching pipe 130. Wherein, the side wall of the water passing pipe 110 is provided with a water passing opening 112 communicated with the water passing channel 111, the side wall of the switching pipe 130 is provided with a switching opening 132 communicated with the switching channel 131, and the water dividing head 140 is provided with a first water outlet channel 141 and a second water outlet channel 142 respectively communicated with the switching channel 131.

It should be noted that, as shown in fig. 2 and fig. 3, in the present embodiment, the switching opening 132 and the water passing opening 112 are both rectangular openings respectively disposed on the side walls of the switching pipe 130 and the water passing pipe 110, wherein the length of the switching opening 132 along the moving direction of the switching pipe 130 is smaller than the length of the water passing opening 112. The switching tube 130 is movable back and forth under the driving of the push rod 150, so that different communication relations between the first water outlet channel 141, the second water outlet channel 142 and the switching channel 131 can be realized, and the following specific conditions applied to the shower head through the switching mechanism 100 are as follows:

as shown in fig. 4, which is a first state of the switching mechanism 100, in which the switching opening 132 is communicated with the lower portion of the water passing opening 112, the first and second

water outlet passages

141 and 142 are communicated with the switching passage 131, respectively. At this time, the water from the first and second

water outlet channels

141 and 142 flows into the first and second

water outlet cavities

210 and 220, respectively, so as to realize the first water outlet state of the shower head.

As shown in fig. 5, which is a second state of the switching mechanism 100, in which the switching opening 132 is communicated with the upper portion of the water passing opening 112, only the first water outlet passage 141 is communicated with the switching passage 131. At this time, the water from the first water outlet channel 141 flows into the first water outlet cavity 210, and the second water outlet state of the shower head is realized.

As shown in fig. 6 and 7, which are the third state of the switching mechanism 100, the switching opening 132 is not directly communicated with the water passing opening 112, and only the first water outlet passage 141 is communicated with the switching passage 131. At this time, the water from the water passing opening 112 flows out to the switching opening 132 and the lower port of the switching tube 130 along the gap between the outer wall of the switching tube 130 and the water passing tube 110, and further flows into the switching passage 131. Since the gap between the outer wall of the switching tube 130 and the water passing tube 110 is relatively small, in the third state, the water flow and the water pressure flowing from the switching channel 131 into the first water outlet chamber 210 through the first water outlet channel 141 are both smaller than those in the second state, and are more gentle.

As shown in fig. 4, 5 and 6, in the present embodiment, the switching mechanism 100 further includes a first seal ring 170, a second seal ring 180 and a third seal ring 190, which are all V-shaped seal rings. The first sealing ring 170 is located between the first water outlet channel 141 and the water inlet of the second water outlet channel 142, and the first sealing ring 170 is disposed on the water dividing head 140. When the switching tube 130 moves forward under the driving of the push rod 150 and the first sealing ring 170 is sleeved on the switching tube 130, the communication between the second water outlet channel 142 and the switching channel 131 is cut off, and the water from the switching channel 131 can be discharged only from the first water outlet channel 141. The second and third sealing rings 180 and 190 are respectively sleeved on the switching tube 130 and sandwiched between the side wall of the switching tube 130 and the switching seat 120 to prevent water from leaking out of the switching mechanism 100.

It should be noted that, in another embodiment, the water distribution head 140 may be provided with other numbers of water outlet channels, and the water outlet channels are communicated with the switching channel 131, and the switching is also realized by the activity of the switching pipe 130, which is not described herein again.

As shown in fig. 3, in the present embodiment, the side wall of the switching tube 130 is provided with a connecting portion 133, the switching seat 120 is provided with an opening through which the connecting portion 133 passes, and the push rod 150 is detachably disposed on the connecting portion 133. The connecting portion 133 is a protrusion in a shape of a Chinese character 'tu'. In addition, in the present embodiment, the switching mechanism 100 further includes a push button 160 disposed on the push rod 150. In the actual operation process, the push rod 150 and the switching tube 130 can be driven to move back and forth only by pushing the push button 160.

Through the above scheme of the embodiment, the switching mechanism 100 of the present disclosure can realize the switching function by pushing the push button 160.

As shown in fig. 1, 4, 5, 6 and 7, the present embodiment further provides a water outlet device, which includes a housing mechanism 300, a switching mechanism 100, and a water outlet mechanism 200. The switching mechanism 100 and the water outlet mechanism 200 are respectively disposed on the housing mechanism 300, the water outlet mechanism 200 is provided with a first water outlet cavity 210 and a second water outlet cavity 220, the first water outlet cavity 210 is communicated with the first water outlet channel 141, the second water outlet cavity 220 is communicated with the second water outlet channel 142, and the second water outlet cavity 220 is disposed around the first water outlet cavity 210. The water outlet mechanism 200 is prior art in the art and will not be described herein. The switching mechanism 100 is the switching mechanism 100 described in the embodiment.

In a specific operation, the push button 160 is pushed forward and backward to switch the water outlet of the water outlet device, and the switching principle is described in the switching mechanism 100, and will not be described herein again. When the switching mechanism 100 is in the first state, both the first water outlet chamber 210 and the second water outlet chamber 220 are in the water outlet state. When the switching mechanism 100 is in the second state, only the first water outlet chamber 210 is in the water outlet state. When the switching mechanism 100 is in the third state, only the first water outlet cavity 210 is in the water outlet state, and the water outlet pressure and the flow rate are small.

It should be noted that, in this embodiment, the water outlet device is a handheld shower head. In other embodiments, the water outlet device may be a faucet, a spray gun, a side spray, etc., and will not be described herein.

Through the above scheme of this embodiment, the water outlet apparatus of this embodiment can realize the water outlet switching of the water outlet apparatus by the pushing operation mode through the arrangement of the switching mechanism 100 of this embodiment. Compared with the prior art, the switch has larger operation stroke by pressing, and better operation hand feeling is achieved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
