In this embodiment, the cleaning liquid contained in the cleaning liquid container 2 can be shower gel, etc. The cleaning liquid container 2 is detachably connected to the water outlet tray 12.

[0026] The shower head further includes a control mechanism 3 and a Venturi structure 4. The Venturi structure 4 is arranged on the water inlet channel 132, the connecting channel 151 is connected between the cleaning liquid container 2 and the Venturi structure 4, and the connecting channel 151 is also provided with an air inlet 152. The control mechanism 3 is arranged on the connecting channel 151 and is located downstream of the air inlet 152 and the cleaning liquid container 2, and the control mechanism 3 is used to control the opening and closing of the connecting channel 151; when the water inlet channel 132 is flowing and the connecting channel 151 is opened, the Venturi structure 4 is configured to apply negative pressure to the connecting channel 151 to absorb the cleaning liquid and gas.

[0027] The water inlet pipe 13 includes a water inlet section 133 and a water outlet section 134, one of the water inlet section 133 or the water outlet section 134 includes a plug-in channel 135, the other of the water inlet section 133 or the water outlet section 134 includes a plug connector 136 adapted to be plugged into the plug-in channel 135, the Venturi structure 4 is arranged in the plug-in channel 135, and the connecting channel 151 is connected to the plug-in channel 135.

[0028] The Venturi structure 4 includes a diameter-contracting structure 41 that gradually necks along the water flow direction in the water inlet channel 132, and the diameter-contracting structure 41 includes a water inlet end and a water outlet end, the water inlet end is correspondingly connected to the water inlet section 133, and the water outlet end is correspondingly connected to the water outlet section 134, and the inner diameter of the water outlet end is smaller than the inner diameter of the inlet of the water outlet section 134. A gap 43 is formed between the diameter-reducing structure 41 and the plug-in channel 135. The venturi structure 4 also includes a liquid suction port 42 formed on the water inlet pipe 13. The liquid suction port 42 connects the connecting channel 151 and the gap 43. The liquid suction port 42 is arranged on the wall of the plug-in channel 135. When the water in the water inlet channel 132 passes through the diameter-reducing structure 41, the flow rate is accelerated, and negative pressure is generated on the liquid suction port 42. Since the liquid suction port 42 is connected to the connecting channel 151, the negative pressure generated in the connecting channel 151 can simultaneously absorb cleaning liquid from the cleaning liquid container 2 and air from the air inlet 152. The cleaning liquid, air and water in the water inlet channel 132 are mixed into foam water and sprayed out from the water outlet cover. When the control mechanism 3 closes the connecting channel 151, the shower head no longer emits foam water.

[0029] The control mechanism 3 includes a rotating plunger 31, a push button 32 and a switching rack 33; the push button 32 is connected to the rotating plunger 31 through a gear rack structure, and the push button 32 can be pushed to move to drive the rotating plunger 31 to rotate to switch between a closed position that blocks the connecting channel 151 and an open position that opens the connecting channel 151. The gear rack structure includes a switching rack 33 connected to the push button 32 and a gear disposed on the rotating plunger 31, and the switching rack 33 is meshed with the gear.

[0030] In this embodiment, the water inlet channel 132, the connecting channel 151, and the control mechanism 3 are arranged on the handle 11; the push button 32 is configured to move along the length direction of the handle 11, and the rotation axis of the rotating plunger 31 is configured to be perpendicular to the length direction of the handle 11. The configuration of the push button 32 and the rotating plunger 31 enables the push button 32 control to be realized in the handle 11 with a small space.

[0031] The rotating plunger 31 includes a rotating body 311, a spring 312 and a plunger 313; the rotating body 311 is linked with the push button 32; the spring 312 is connected between the rotating body 311 and the plunger 313, and the spring 312 is used to push the plunger 313 to abut against the inner wall of the connecting channel 151 to achieve blocking. A cylindrical space 153 is formed in the connecting channel 151, one side of the cylindrical space 153 is connected to the air inlet 152 and the cleaning liquid container 2, and the other side of the cylindrical space 153 forms a liquid outlet and is connected to the liquid suction port 42. The plunger 313 is supported by elastic rubber or silicone, and the plunger 313 is pushed by the spring 312 to abut against the inner wall of the cylindrical space 153 to block the liquid outlet.

[0032] A first one-way check device 5 is also provided at the connection between the cleaning liquid container 2 and the connecting channel 151. The first one-way check device 5 is composed of a one-way valve 51 and a check valve 52. The one-way valve 51 is located upstream of the check valve 52. The first one-way check device 5 can prevent the cleaning liquid in the connecting channel 151 from flowing back to the cleaning liquid container 2. The check valve 52 includes a first check wall 521 that gradually shrinks in diameter along the water flow direction in the connecting channel 151, and the diameter of the front end opening of the first check wall 521 is smaller than the rear end opening of the first check wall 521, which can prevent a large amount of cleaning liquid from flowing back.

[0033] The cleaning liquid container 2 includes a switch cover 21, and the switch cover 21 is used to close a liquid filling port 22 of the cleaning liquid container 2; a second one-way check device 211 is provided on the switch cover 21. The second one-way check device 211 can prevent the cleaning liquid in the cleaning liquid container 2 from flowing out, and can also maintain the air pressure balance between the cleaning liquid container 2 and the outside air. The second one-way check device 211 includes a second check wall 212, and the second check wall 212 gradually expands in diameter in the direction away from the cleaning liquid container 2. The lower end opening of the second check wall 212 is smaller than the upper end opening of the second check wall 212, and the two openings are connected to the cleaning liquid container 2 and the air respectively, which plays a role in air pressure balance.

[0034] The water outlet cover is rotatably arranged on the water outlet tray 12, and is provided with a plurality of water outlet holes, which are connected to the water inlet channel 132, and the plurality of water outlet holes correspond to a plurality of water spray forms respectively; the water outlet cover is rotated to switch the water outlet holes to discharge water. The venturi structure 4 corresponds to a critical water flow velocity, and when it is greater than the critical water flow velocity, the venturi structure 4 generates a negative pressure to absorb cleaning liquid and gas; wherein, in at least one water spray form, the water flow velocity in the water inlet channel 132 is less than the critical water flow velocity, and in at least one water spray form, the water flow velocity in the water inlet channel 132 is greater than or equal to the critical water flow velocity. In this embodiment, the water outlet cover is rotated so that the water outlet cover discharges high-pressure water, shower water and spray water. When spray water is discharged, the water flow velocity in the water inlet channel 132 is less than the critical water flow velocity. Therefore, even if the control mechanism 3 opens the connecting channel 151, no foam will be produced under the spray water. When high-pressure water and shower water are discharged, the water flow velocity in the water inlet channel 132 is greater than or equal to the critical water flow velocity. Therefore, when high-pressure water or shower water is discharged, foam is produced.

[0035] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
