[0030] Referring to Figure 1 and Figure 2The embodiment of the present application discloses a water spray function switching shower, comprising a shell 1, a driving assembly 2, a swing assembly 3 and a water distribution assembly 4, the shell 1 comprises a fixed cover 11 and a surface cover 12, the fixed cover 11 is provided with a water inlet hole 111 and a water inlet cavity 112, when water enters the water spray function switching shower, it first enters from the water inlet hole 111 and then flows into the water inlet cavity 112 from the water inlet hole 111. When water is discharged, the surface cover 12 is provided with a plurality of water outlet nozzles 121, water is sprayed from the water outlet nozzles 121 to form water spray. The driving assembly 2 comprises a piston 21, after water enters from the water inlet hole 111, under the action of water pressure, water can drive the piston 21 to move in the water inlet cavity 112, specifically to drive the piston 21 to move close to the swing assembly 3 and the water distribution assembly 4.

[0031] In order to drive the swing assembly 3 and the water distribution assembly 4 to switch, the swing assembly 3 comprises a switching plate 31 and a swing block 32, the two sides of the switching plate 31 are respectively provided with a first push groove 311 and a second push groove 312, one end of the swing block 32 is hinged to the piston 21, the other end is provided as a pushing end 321, since it is hinged connection, the swing block 32 can swing around the hinge, specifically, after the pushing end 321 is inserted into the first push groove 311 or the second push groove 312, it will swing under the continuous driving force of water pressure. The water distribution assembly 4 comprises a water distribution seat 41, the middle part of the switching plate 31 is hinged to the water distribution seat 41, the switching plate 31 can tilt and swing around the hinge. When water enters, water pressure drives the piston 21 to move towards the direction close to the swing assembly 3 and the water distribution assembly 4, at this time, the pushing end 321 remains in the vertical state, and the switching plate 31 is in the inclined state, the first push groove 311 or the second push groove 312 is located below the pushing end 321, when the pushing end 321 contacts the first push groove 311 or the second push groove 312, under the continuous action of water pressure, the swing block 32 will continue to move towards the switching plate 31 along with the piston 21, since the length of the swing block 32 is fixed, the first push groove 311 or the second push groove 312 will force the pushing end 321 to move laterally, thereby driving the swing block 32 to swing, in the process of swinging, the swing block 32 continues to move towards the switching plate 31 and finally inserts into the first push groove 311 or the second push groove 312, when the pushing end 321 is inserted into the bottom of the first push groove 311 or the second push groove 312, the pushing end 321 will continue to push the switching plate 31, so that the switching plate 31 inclines towards the pushing end 321.

[0032] The water distribution seat 41 is provided with a first water distribution opening 411 and a second water distribution opening 412, the switching plate 31 is provided with a first water blocking block 313 and a second water blocking block 314 at two ends corresponding to the first push groove 311 and the second push groove 312 respectively, the positions of the first water blocking block 313 and the second water blocking block 314 correspond to the positions of the first water distribution opening 411 and the second water distribution opening 412 respectively, and the first water blocking block 313 and the second water blocking block 314 can block the first water distribution opening 411 and the second water distribution opening 412 respectively. When the switching plate 31 is in an inclined state, the first water blocking block 313 or the second water blocking block 314 at one end will block the first water distribution opening 411 or the second water distribution opening 412, so that when the pushing end 321 abuts against the first push groove 311 or the second push groove 312, the inclination direction of the switching plate 31 will be changed, and after the inclination direction of the switching plate 31 is changed, the pushing end 321 will continue to push the switching plate 31, so that the first water blocking block 313 or the second water blocking block 314 can block the first water distribution opening 411 or the second water distribution opening 412, thereby diverting water to the second water distribution opening 412 or the first water distribution opening 411, and completing the switching of the water flow direction. Therefore, the swing block 32 can follow the reciprocating movement of the piston 21, the pushing end 321 can be inserted into the first push groove 311 and push the first push groove 311 to make the first water blocking block 313 block the first water distribution opening 411, or the pushing end 321 can be inserted into the second push groove 312 and push the second push groove 312 to make the second water blocking block 314 block the second water distribution opening 412. The pushing end 321 can only push a single push groove at the same time, so the switching plate 31 can only tilt and swing in one direction at the same time, so that the water flow has a diversion characteristic. By changing the direction of the pushing end 321, the switching between the communication between the first water distribution opening 411 and the second water distribution opening 412 can be realized.

[0033] The water distribution assembly 4 further comprises a water distribution disc 42, the water distribution disc 42 is provided with a first water distribution area 421 and a second water distribution area 422, the first water distribution area 421 and the second water distribution area 422 are in communication with the first water distribution opening 411 and the second water distribution opening 412 respectively, and the first water distribution area 421 and the second water distribution area 422 are in communication with the water outlet nozzle 121, so that after the water is diverted by the switching plate 31, it can be sprayed from the water outlet nozzle 121 in the first water distribution area 421 or the water outlet nozzle 121 in the second water distribution area 422, and by changing the direction of the pushing end 321, the switching between the water sprayed from the first water distribution area 421 and the water sprayed from the second water distribution area 422 can be realized, so that the swing assembly 3 and the water distribution assembly 4 can realize the effect of switching water with different water spray functions.

[0034] The beneficial effects of the embodiments of the present application are as follows:

[0035] The water spray function switching shower of the embodiments of the present application is provided with a shell 1, a driving assembly 2, a swing assembly 3 and a water distribution assembly 4, wherein the shell 1 comprises a fixed cover 11, the driving assembly 2 comprises a piston 21, the swing assembly 3 comprises a switching plate 31 and a swing block 32, and the water distribution assembly 4 comprises a water distribution seat 41. When water enters the water spray function switching shower, it will first enter the fixed cover 11. Under the drive of water pressure, the piston 21 will move towards the direction close to the switching plate 31. The swing block 32 will move along with the piston 21. Since the switching plate 31 is provided with a first push groove 311 and a second push groove 312, the swing block 32 will separately insert into the second push groove 312 or the first push groove 311 when close to the switching plate 31. After insertion, it will push the switching plate 31 to tilt and swing to one side, so that the first water blocking block 313 or the second water blocking block 314 on the switching plate 31 respectively blocks the first water distribution port 411 or the second water distribution port 412 in the water distribution seat 41. The first water distribution port 411 and the second water distribution port 412 are respectively communicated with water outlet nozzles 121 in different areas. The water outlet nozzles 121 in different areas correspond to different water spray functions. Therefore, the swing of the swing block 32 and the switching plate 31 can realize the switching of the water spray function. The switching mechanism only has the swing block 32 and the switching plate 31, and the mechanism is simple and stable in use.

[0036] Referring to Figure 4 , both sides of the swing block 32 are respectively provided with swing plates 322. The bottoms of the swing plates 322 are connected with each other to form the pushing end 321. The mutual connection can lengthen the length of the pushing end 321, thereby improving the strength of the pushing end 321. The upper parts of the swing plates 322 are respectively provided with hinge holes 323. The swing block 32 is hinged with the inner cavity of the piston 21 through the hinge holes 323, so that the swing block 32 can swing around the hinge holes 323. Both sides of the swing plate 322 are respectively provided with elastic arms 324. The elastic arms 324 are gradually expanded downward from the upper parts of the swing plates 322. The elastic arms 324 and the swing plates 322 form a “” character. The elastic arms 324 have elasticity. When the swing block 32 swings, the elastic arms 324 can abut against the inner cavity of the piston 21. The elastic arms 324 abutting against the piston 21 can provide the swing block 32 with elastic force for rebounding and resetting. When water stops, the water pressure acting on the piston 21 disappears, and the piston 21 will gradually move away from the switching plate 31 to reset. At this time, the elastic arms 324 in the inner cavity of the piston 21 can assist the swing block 32 to reset, so that the pushing end 321 can finally reset to a vertical state, preparing for the next pushing.

[0037] Referring to Figure 3 , the upper part of the switching plate 31 is respectively provided with a first protrusion 315, a third protrusion 317 and a second protrusion 316 in sequence, the third protrusion 317 is located between the first protrusion 315 and the second protrusion 316, the first push groove 311 is arranged in the recess between the first protrusion 315 and the third protrusion 317, and the second push groove 312 is arranged in the recess between the second protrusion 316 and the third protrusion 317. In this embodiment, the two sides of the third protrusion 317 are inclined planes, and in other embodiments, they can also be circular arc surfaces. When the switching plate 31 is inclined towards the first protrusion 315 or towards the second protrusion 316, the two sides of the third protrusion 317 can respectively guide the insertion of the pushing end 321 into the second push groove 312 or the first push groove 311.

[0038] Referring to Figures 5-8 , in order to achieve the guiding effect, the third protrusion 317 is located below the pushing end 321 in the vertical state. When the switching plate 31 is inclined, for example, when the switching plate 31 is inclined towards the first protrusion 315, the top of the third protrusion 317 will be inclined towards the side of the first protrusion 315. Therefore, when the pushing end 321 moves towards the switching plate 31, the pushing end 321 will be guided by the side of the third protrusion 317 close to the second protrusion 316, so that the pushing end 321 is inserted into the second push groove 312, thereby making the switching plate 31 inclined in the opposite direction of the previous inclined state. Conversely, when the switching plate 31 is inclined towards the second protrusion 316, the top of the third protrusion 317 will be inclined towards the side of the second protrusion 316. Therefore, when the pushing end 321 moves towards the switching plate 31, the pushing end 321 will be guided by the side of the third protrusion 317 close to the first protrusion 315, so that the pushing end 321 is inserted into the first push groove 311. During use, due to the repeated guidance of the two sides of the third protrusion 317, the pushing end 321 can be continuously circulated between the insertion of the first push groove 311 and the second push groove 312 during reciprocating movement, so that the water spray function is also circulated and switched.

[0039] The first water blocking block 313 is arranged on one side of the first protrusion 315 away from the third protrusion 317, and the second water blocking block 314 is arranged on one side of the second protrusion 316 away from the third protrusion 317. The shapes of the first water blocking block 313 and the second water blocking block 314 correspond to the shapes of the openings of the first water distribution port 411 and the second water distribution port 412 respectively. Therefore, when the switching plate 31 is inclined towards the side where the first protrusion 315 is located, the first water blocking block 313 can block the first water distribution port 411, and when the switching plate 31 is inclined towards the side where the second protrusion 316 is located, the second water blocking block 314 can block the second water distribution port 412.

[0040] In order to improve the sealing performance of the water spray function switching shower, the oscillating assembly 3 further comprises an oscillating pin 33, a positioning pin 34 and a supporting spring 35. The bottom of the oscillating pin 33 is provided with a hinged column 331 which abuts against the water distribution seat 41. The water distribution seat 41 is provided with a containing cavity 413 which has sufficient space for the switching plate 31 to drive the oscillating pin 33 to oscillate around the hinged column 331 in the containing cavity 413 when the switching plate 31 oscillates. The oscillation of the oscillating pin 33 is related to the inclined oscillation of the switching plate 31. Specifically, the positioning pin 34 is slidably connected with the oscillating pin 33, and the supporting spring 35 is arranged between the positioning pin 34 and the oscillating pin 33. The top of the positioning pin 34 abuts against the bottom of the switching plate 31. When the switching plate 31 oscillates, the positioning pin 34 will oscillate under the inclined thrust of the bottom of the switching plate 31. The bottom of the switching plate 31 is provided with an abutting groove 318, and the two sides of the abutting groove 318 are respectively provided with a first inclined surface 3181 and a second inclined surface 3182. The first inclined surface 3181 is arranged on one side of the abutting groove 318 close to the first water blocking block 313, and the second inclined surface 3182 is arranged on one side of the abutting groove 318 close to the second water blocking block 314. When the oscillating pin 33 oscillates, the top of the positioning pin 34 can slide between the first inclined surface 3181 and the second inclined surface 3182 respectively.

[0041] Specifically, when the pushing end 321 is inserted into the first pushing groove 311, the switching plate 31 swings towards the first protrusion 315, at this time the top of the positioning pin 34 slides from the first inclined surface 3181 to the second inclined surface 3182, under the action of the supporting spring 35, the positioning pin 34 continuously generates pressure on the second inclined surface 3182, which is basically opposite to the pushing direction of the pushing end 321 on the first pushing groove 311, so that the pushing end 321 firmly presses the first pushing groove 311, thereby making the first water blocking block 313 tightly block the first water outlet 411; on the contrary, when the pushing end 321 is inserted into the second pushing groove 312, the switching plate 31 swings towards the second protrusion 316, at this time the top of the positioning pin 34 slides from the second inclined surface 3182 to the first inclined surface 3181, under the action of the supporting spring 35, the positioning pin 34 continuously generates pressure on the first inclined surface 3181, which is basically opposite to the pushing direction of the pushing end 321 on the second pushing groove 312, so that the pushing end 321 firmly presses the second pushing groove 312, thereby making the second water blocking block 314 tightly block the second water outlet 412. Therefore, in cooperation with the pushing force of the swinging block 32 on the switching plate 31, the first water blocking block 313 or the second water blocking block 314 can maintain a better water blocking state, that is, even at low water pressure, it can have a better sealing effect.

[0042] In order to facilitate the resetting of the piston 21 when the water is stopped, the driving assembly 2 further comprises a resetting spring 22, the middle part of the water distribution seat 41 is provided with a spring placing cavity 414, the resetting spring 22 is arranged in the spring placing cavity 414, one end of the resetting spring 22 abuts against the water distribution seat 41, and the other end abuts against the top of the piston 21. When water enters the fixed cover 11, the piston 21 moves relative to the water distribution seat 41 towards the switching plate 31, and the resetting spring 22 is in a compressed state. When the water force is greater than the action force of the resetting spring 22, the piston 21 continues to move downward. When the water is stopped, the action force of the resetting spring 22 is greater than the water force, thereby driving the piston 21 to move away from the switching plate 31, thereby moving away from the swinging block 32, and under the action of the elastic force of the swinging arm, the swinging block 32 returns to the vertical state, achieving the effect of resetting. Since the resetting spring 22 always has an action force on the piston 21 away from the switching plate 31, if there is no swinging pin 33, positioning pin 34 and supporting spring 35, the pushing effect of the pushing end 321 on the first pushing groove 311 or the second pushing groove 312 will be greatly reduced, and the sealing of the first water outlet 411 or the second water outlet 412 will not be tight.

[0043] In the process that the piston 21 moves towards the switch plate 31, in order to enable water to flow from the fixed cover 11 into the water distribution seat 41, a plurality of water outlet openings 113 are arranged in the water inlet cavity 112, the water outlet openings 113 are arranged between the piston 21 and the switch plate 31, when the piston 21 moves to the water outlet openings 113, water can enter the first water distribution opening 411 or the second water distribution opening 412 from the water inlet cavity 112, so as to achieve the effect of pushing the piston 21 and the effect of water passing. The shell 1 further comprises a screw cover 13, the screw cover 13 is sleeved outside the water distribution seat 41, the screw cover 13 is provided with a through hole 131, water can enter the fixed cover 11 through the through hole 131, the water flower function switch shower head can be communicated with the external water pipe through the screw cover 13.

[0044] The above is the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the principles of the present application, can also make a number of improvements and refinements, these improvements and refinements also regarded as the protection scope of the present application.
