The liquid outlet pipe 61 is used to extract the cleaning liquid in the cleaning liquid container. During use, due to the action of the counterweight 62, the counterweight 62 is affected by gravity and will drive the liquid outlet pipe 61 to move to or near the lowest point of the cleaning liquid container. There are many forms of movement of the liquid outlet pipe 61. In this embodiment, the liquid outlet pipe 61 is a flexible pipe 6141, and the counterweight 62 is arranged on the free end 612 of the liquid outlet pipe 61. Therefore, under the action of gravity, the free end 612 of the liquid outlet pipe 61 will droop to the lowest point of the cleaning liquid container. It should be noted that the connection between the counterweight and the liquid outlet pipe can be a detachable connection, an integral connection, a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, including but not limited to insert injection molding, hot melt connection, snap connection, plug connection, etc. For those of ordinary skill in the art, it can be set according to specific circumstances. In this embodiment, a filter tip 63 is arranged at the free end 612 of the liquid outlet pipe 61. The filter tip 63 can filter the cleaning liquid to prevent the problem of agglomeration caused by the high viscosity of the cleaning liquid, thereby avoiding the problem of blocking the liquid outlet pipe 61.

[0036] In this embodiment, at least part of the liquid outlet pipe 61 is rotatably arranged in the cleaning liquid container 2. The liquid outlet pipe 61 is rotatably arranged in the cleaning liquid container 2, which can enable the free end 612 to move relative to the fixed end 611 when affected by gravity.

[0037] The liquid outlet pipe 61 includes a first liquid outlet section 613, a second liquid outlet section 614 and a liquid outlet seat 615.

The liquid outlet structure 6 includes a liquid outlet pipe 61, a counterweight 62, a filter tip 63, a hose 6141, a rotating elbow 6142 and a fastener 6143. The counterweight 62 and the filter tip 63 form a component and are connected to the rotating elbow 6142 by the hose 6141. The rotating elbow 6142 can rotate around the circumference of the cleaning liquid container. When the rotating elbow 6142 rotates, the counterweight 62 and the filter tip 63 rotate accordingly. At this time, if the liquid suction function of the shower head is turned on, the cleaning liquid is sucked in from the filter tip 63, enters the hose 6141, then enters the rotating elbow 6142, and then enters the first liquid outlet section 613. When taking a bath, holding the shower head at any angle, the shower head can suck the liquid from the cleaning liquid container.

[0039] The liquid outlet structure and the liquid suction structure will be described in more detail below.

[0040] The shower head body forms the water outlet structure. Specifically, the shower head body includes a handle 11 and a water outlet plate 12. One end of the handle 11 is connected to the water outlet plate 12. A water outlet face cover is provided on one side end face of the water outlet plate 12. The other end face of the water outlet plate 12 is connected to the cleaning liquid container 2. The shower head body includes a water inlet pipe 13 and a water distributor 14 provided in the handle 11 and the water outlet plate 12. One end of the water inlet pipe 13 extends outside the handle 11 to form a water inlet joint 131. A water inlet channel 132 is formed in the water inlet pipe 13. A connecting pipe 15 is connected between the cleaning liquid container 2 and the water inlet pipe 13. The connecting pipe 15 is provided in the handle 11. A connecting channel 151 is formed in the connecting pipe 15. In this embodiment, the cleaning liquid contained in the cleaning liquid container 2 can be body wash, etc. The cleaning liquid container 2 is detachably connected to the water outlet plate 12.

[0041] The liquid suction structure includes a control mechanism 3, a Venturi structure 4, and the connecting channel 151. The Venturi structure 4 is provided on the water inlet channel 132. The connecting channel 151 is connected between the liquid outlet structure 6 and the Venturi structure 4. The connecting channel 151 is further configured with an air inlet 152. The control mechanism 3 is provided on the connecting channel 151 and is located downstream of the air inlet 152 and the cleaning liquid container 2. The control mechanism 3 is used to control the on-off of the connecting channel 151. When water passes through the water inlet channel 132 and the connecting channel 151 is opened, the Venturi structure 4 is configured to apply negative pressure to the connecting channel 151 to suck the cleaning liquid and gas.

[0042] 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 136 that is adaptively plugged into the plug-in channel 135. The Venturi structure 4 is provided in the plug-in channel 135. The connecting channel 151 communicates with the plug-in channel 135.

[0043] The Venturi structure 4 includes a diameter-reducing structure 41 that gradually constricts along the water flow direction in the water inlet channel 132. The diameter-reducing 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. 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 insertion channel 135. The Venturi structure 4 further includes a liquid suction port 42 formed on the water inlet pipe 13. The liquid suction port 42 connects the connection channel 151 and the gap 43. The liquid suction port 42 is provided on the wall of the insertion channel 135. When the water flow in the water inlet channel 132 passes through the diameter-reducing structure 41, due to the increased flow rate, a negative pressure is generated on the liquid suction port 42. Since the liquid suction port 42 is connected to the connection channel 151, the negative pressure generated in the connection channel 151 can simultaneously suck the cleaning liquid from the cleaning liquid container 2 and suck air from the air inlet 152. The cleaning liquid, air, and water in the water inlet channel 132 are mixed into foamed water and sprayed out from the water outlet surface cover. When the control mechanism 3 closes the connection channel 151, the shower head no longer sprays foamed water.

[0044] The control mechanism 3 includes a rotary plunger 31, a push button 32, and a switching rack 33. The push button 32 is connected to the rotary plunger 31 through a gear-rack structure. The push button 32 is movably pushed to drive the rotary plunger 31 to rotate to switch between a closed position that blocks the connection channel 151 and an open position that opens the connection channel 151. The gear-rack structure includes a switching rack 33 connected to the push button 32 and a gear provided on the rotary plunger 31. The switching rack 33 meshes with the gear.

[0045] In this embodiment, the water inlet channel 132, the connection channel 151, and the control mechanism 3 are provided 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 rotary plunger 31 is configured to be perpendicular to the length direction of the handle 11. The configurations of the push button 32 and the rotary plunger 31 enable the control of the push button 32 to be achieved on the handle 11 with a relatively small space.

[0046] 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 connection passage 151 to achieve sealing. A cylindrical space 153 is formed in the connection passage 151. One side of the cylindrical space 153 communicates with the air inlet 152 and the cleaning liquid container 2, and the other side of the cylindrical space 153 forms a liquid outlet and communicates with the liquid suction port 42. The plunger 313 is supported by rubber or silica gel of elastic material, and the plunger 313 is pushed by the spring 312 to abut against the inner wall of the cylindrical space 153 so as to seal the liquid outlet.

[0047] A first one-way check device 5 is further provided at the connection between the cleaning liquid container 2 and the connection passage 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 connection passage 151 from flowing back into the cleaning liquid container 2. The check valve 52 includes a first check surrounding wall 521 that gradually tapers along the water flow direction in the connection passage 151. The diameter of the front end opening of the first check surrounding wall 521 is smaller than that of the rear end opening of the first check surrounding wall 521, which can prevent a large amount of cleaning liquid from flowing back.

[0048] 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 surrounding wall 212, and the second check surrounding wall 212 gradually expands in diameter along the direction away from the cleaning liquid container 2. The lower end opening of the second check surrounding wall 212 is smaller than the upper end opening of the second check surrounding wall 212, and its two openings communicate with the cleaning liquid container 2 and the air respectively, playing a role in air pressure balance.

[0049] The water outlet surface cover is rotatably arranged on the water outlet tray 12. A variety of water outlet holes are arranged on the water outlet surface cover. The water outlet holes are connected to the water inlet channel 132, and the variety of water outlet holes respectively correspond to a variety of water flower forms; the water outlet surface cover rotates to be able to switch the water outlet of the water outlet holes. The Venturi structure 4 corresponds to a critical water flow velocity. When the water flow velocity is greater than the critical water flow velocity, the Venturi structure 4 generates negative pressure to suck the cleaning liquid and gas; wherein, in at least one water flower 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 flower 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 surface cover rotates to make the water outlet surface cover discharge strong pressure water, sprinkler water and spray water. When discharging spray water, 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 connection channel 151, no foam will be discharged under the spray water. When discharging strong pressure water and sprinkler water, the water flow velocity in the water inlet channel 132 is greater than or equal to the critical water flow velocity. Therefore, foam is discharged when discharging strong pressure water or sprinkler water.
