The inlet end 441 of the feedback channel is connected to the control chamber outlet 422 and the water outlet channel 43. The outlet end 442 of the feedback channel is connected to the connection between the water inlet channel 41 and the control chamber inlet 421. The outlet ends 442 of the two feedback channels are arranged opposite to each other.

[0061] like Figure 5 and Figure 6 As shown, in this embodiment, grooves 423 concave outwards are respectively provided on the inner walls on both sides of the control cavity 42, and the two grooves 423 are symmetrically arranged.

[0062] like Figure 5 and Figure 6 As shown, in this embodiment, a flow dividing wall 424 is provided between the two control chamber outlets 422 , and the inner wall of the flow dividing wall 424 is an arc surface convex outwards.

[0063] Continue reading Figure 5 and Figure 6In this embodiment, the alternating water outlet structure is provided on the top surface of the cover 30 and is provided with a water baffle 33 provided in the diameter direction in the middle of the top surface. The water baffle 33 symmetrically divides the water outlet cavity surrounded by the top surface into a first water outlet cavity 34 and a second water outlet cavity 35. A plurality of first water outlet holes 31 are provided and communicate with the first water outlet cavity 34. A plurality of second water outlet holes 32 are provided and communicate with the second water outlet cavity 35. The inlets of the two water outlet cavities are correspondingly communicated with the two control cavity outlets 422. The first water outlet cavity 34 and the second water outlet cavity 35 form a water outlet channel 43. The inlet ends of the two feedback channels 44 are respectively correspondingly communicated with the two water outlet cavities 34 and 35. The two feedback channels 44 are provided on the top surface of the cover 30 and extend along the periphery of the cover 30.

[0064] In this embodiment, a sealing plate 50 is further provided in the main body 10, and the sealing plate 50 and the surface cover 30 are sealed to form a water outlet chamber, and the water outlet chamber is divided into a first water outlet chamber 34 and a second water outlet chamber 35 by a water baffle 33. A plurality of first water outlet holes 31 are provided and connected to the first water outlet chamber 34, a plurality of second water outlet holes 32 are provided and connected to the second water outlet chamber 35, and the water dividing plate 20 is fixed on the side of the sealing plate 50 facing away from the water outlet chamber.

[0065] The working principle of this embodiment is briefly described as follows:

[0066] like Figure 6As shown, when water flows into the water inlet channel 41 on the cover 30 through the water diversion plate 20 and then flows into the control chamber 42, due to the instability of the high-speed water flow in a turbulent state, under the Coanda effect, the water flow entering the control chamber 42 will deviate to one side and flow along the left inner wall or the right inner wall of the control chamber 42 to the corresponding left control chamber outlet 422 or the right control chamber outlet 422. Assuming that at the beginning, most or all of the water flow in the control chamber 42 flows to the left control chamber outlet 422, then at this time, only a small amount of water flow or even no water flow flows to the right control chamber outlet 422, a part of the water flow flowing out of the left control chamber outlet 422 flows to the first water outlet chamber 34 through the left water outlet channel 43, and flows out from the first water outlet hole 31 on the first water outlet chamber 34, and a part of the water is diverted to the left feedback channel 44, and the water flow at the outlet end 442 of the left feedback channel 44 impacts the inlet water flow of the inlet channel 41, so that most or all of the inlet water flow turns to the right inner wall of the control chamber 42, and then flows along the right inner wall to the right control chamber outlet 422, then at this time, only a small amount of water flow or even no water flow flows to the left control chamber outlet 422, and the right control A part of the water flowing out of the cavity outlet 422 flows to the second water outlet cavity 35 through the right water outlet channel 43, and flows out from the second water outlet hole 32 on the second water outlet cavity 35, while a part of the water is diverted to the right feedback channel 44, and the water flow at the outlet end 442 of the right feedback channel 44 impacts the inlet water flow of the water inlet channel 41, so that most of the inlet water flow or all of the inlet water flow deviates to the left inner wall of the control cavity 42, and then flows along the left inner wall to the left control cavity outlet 422, and so on and so forth, so that the first water outlet hole 31 and the second water outlet hole 32 form alternating water outlets. Compared with the existing first water outlet hole 31 and the second water outlet hole 32, the average water outlet has a higher water outlet intensity, the water flow impact is stronger, and the alternating water outlet has a massage function, which makes the spraying experience better.

[0067] See also Figure 7 A pressurized shower head according to a second embodiment of the present invention is mainly different from the first embodiment in that, in the present embodiment, an alternating water outlet structure is disposed on the top surface of a face cover 30 and is provided with two, and correspondingly, the face cover 30 is provided with a first water outlet hole 31 and a second water outlet hole 32 having the same number as the alternating water outlet structure, and the alternating water outlet structure is symmetrically arranged.

[0068] See also Figure 8 A pressurized shower head according to a third embodiment of the present invention is mainly different from the first embodiment in that, in the present embodiment, four alternating water outlet structures are arranged on the top surface of the face cover 30, and correspondingly, the face cover 30 is provided with first water outlet holes 31 and second water outlet holes 32, the same number as the alternating water outlet structures, and the alternating water outlet structures are symmetrically arranged and arranged at annular intervals.

[0069] See also Fig. 9A pressurized shower head according to a fourth embodiment of the present invention mainly differs from the first embodiment in that, in the present embodiment, the inner walls on both sides of the control cavity 42 are straight surfaces inclined outwardly along the water flow direction.

[0070] See also Fig.10 , a pressurized shower head according to the fifth embodiment of the present invention, this embodiment is Fig. 9 The main difference of the fourth embodiment is that, in this embodiment, the inner wall of the diverter wall 424 is an inwardly convex arc surface.

[0071] In other embodiments, the inner wall of the diverter wall 424 may also be a straight surface.

[0072] See also Figures 11 to 13 A sixth embodiment of the present invention is a pressurized shower head. The main difference between this embodiment and the first embodiment is that, in this embodiment, the inner walls on both sides of the control cavity 42 are parallel straight surfaces.

[0073] In other embodiments, the inner walls on both sides of the control cavity 42 may also be designed to be an overall smoothly transitioned arc surface.

[0074] This embodiment also provides three feedback channels 44 of different lengths. Specifically, Fig.11 The feedback channel 44 is the longest, and its water inlet channel 41 is located on one side of the periphery of the top surface of the face cover 30, and the inlet end 441 of the feedback channel is relatively located on the other side of the periphery of the top surface of the face cover 30. Thus, the length of the feedback channel 44 is as large as possible. The longer the length of the feedback channel 44 is, the more obvious the water pressure change is, and the water outlet effect presented is the more obvious the alternating slapping feeling of the water flow out of the first water outlet hole 31 and the water flow out of the second water outlet hole 32. Preferably, the flow rate of the water inlet channel is greater than or equal to 6L / min, the length of the feedback channel is greater than or equal to 100mm, the water pressure change is most obvious, and the alternating slapping feeling of the two water outlet holes is the most obvious.

[0075] Fig.12 The length of the feedback channel 44 shown is Fig.11 The feedback path 44 shown is relatively short in length. Fig.13 The inlet end 411 of the feedback channel 44 is located close to the water inlet channel 41. Fig.13 The length of the feedback channel 44 shown is Fig.12 The length of the feedback channel 44 shown is relatively short. The shorter the length of the feedback channel 44, the greater the oscillation frequency of the water flow from the two water outlet holes 31, 32. In this way, by providing the cover 30 with feedback channels 44 of different lengths for selection, the user can select a suitable water flow oscillation frequency according to personal preference, and more choices are available.

[0076] Of course, in other embodiments, the position of the inlet end 441 of the feedback channel may be directly designed to be adjustable, so that the length of the feedback channel 44 is adjustable, which is more convenient to use.

[0077] See also Figures 14 to 18 The seventh embodiment of the present invention is a pressurized shower head. The main difference between this embodiment and the above embodiments is that the alternating water outlet structure is arranged on the water distribution plate 20 instead of on the surface cover 30.

[0078] Specifically, the alternating water outlet structure is provided with two water flow chambers 36 symmetrically arranged on both sides of the control chamber 42, and two feedback channels 44 are symmetrically arranged outside the two water flow chambers 36. The water outlet channel 43 is connected with the control chamber outlet 422 through the water flow chamber 36, and the axis of the water outlet channel 43 is perpendicular to the surface where the water diversion plate 20 is located.

[0079] Similarly, the length of the feedback channel 44 on the water distribution plate 20 can also be designed to be adjustable, or water distribution plates 20 with feedback channels 44 of different lengths can be provided for selection, so that users can choose the appropriate water flow oscillation frequency according to their personal preferences, with more options.

[0080] The working principle of the alternating water outlet structure of this embodiment is the same as that of the above embodiment, and will not be repeated here.
