DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0037] The embodiment of the present application provides a shower head, such as Figure 1-Figure 5As shown, the shower head includes a water outlet tray 3, a water outlet sleeve 4 and a cover 5 which are sequentially arranged along the water outlet direction. A first water cavity 20 is provided on the side of the water outlet tray 3 which is away from the water outlet sleeve 4, and a second water cavity 30 is provided between the water outlet tray 3 and the water outlet sleeve 4.

[0038] The water outlet tray 3 is provided with a plurality of connecting holes 31, and the connecting holes 31 are connected with the first water chamber 20 and the second water chamber 30 on both sides of the water outlet tray 3; the water outlet sleeve 4 is provided with a plurality of water outlet nozzles 41 connected with the second water chamber 30, and the surface cover 5 is provided with a plurality of water outlet holes 51 corresponding to the water outlet nozzles 41 one by one. Figure 1 As shown, the water outlet 41 can extend from the water outlet hole 51 to the outside of the cover 5;

[0039] Among them, the water outlet sleeve 4 is also provided with a plurality of elastic sealing caps 42 protruding toward the connecting hole 31 and corresponding to the connecting hole 31 one by one, and the side of the surface cover 5 facing the water outlet sleeve 4 is provided with a plurality of supporting structures 52 corresponding to the elastic sealing caps 42 one by one. The elastic sealing caps 42 are configured to block the connecting hole 31 when the shower is turned off. When the shower is turned on, the elastic sealing caps 42 can be deformed by the pressure of the water in the connecting hole 31 to make the connecting hole 31 conductive. The supporting structure 52 is configured to support the elastic sealing cap 42 when the elastic sealing cap 42 is pressed to deform, so that the elastic sealing cap 42 can bounce up and block the connecting hole 31 when the shower is turned off.

[0040] The technical solution provided by the embodiment of the present application is that when the shower is turned on, the water flow of the connecting hole 31 can pressurize the elastic sealing cap 42 to deform it, so that the water of the first water chamber 20 can enter the second water chamber 30 through the connecting hole 31, and the water of the second water chamber 30 can flow out from the water outlet 51 of the face cover 5 through the water outlet 41. When the shower is turned off, the elastic sealing cap 42 pops up to block the connecting hole 31, thereby isolating the water in the first water chamber 20 and the water inlet end, and the small amount of water left in the second water chamber 30 cannot drip out from the water outlet 41 under the action of atmospheric pressure and the adsorption force of the water droplets themselves, thereby achieving the purpose of instant shut-off and instant stop. The embodiment of the present application provides a support structure 52, so that the elastic sealing cap 42 is supported by the support structure 52 when it is squeezed and deformed, which can solve the problem that the elastic sealing cap 42 cannot bounce up when it is squeezed onto the face cover 5, especially when the elastic sealing cap 42 is made of elastic rubber material, the elastic sealing cap 42 may be adsorbed on the face cover 5, thereby causing the elastic sealing cap 42 to be unable to bounce up to seal the connecting hole 31. Therefore, the solution provided by the embodiment of the present application can ensure that each elastic sealing cap 42 can bounce up to seal the connecting hole 31 when the water of the shower is turned off, thereby realizing the rapid water stopping function of the shower.

[0041] In one embodiment, if Figure 2 and Figure 3 As shown (combined Fig. 9 and Fig.10 ), a recessed portion 421 and an annular sealing portion 422 surrounding the recessed portion 421 are formed at the top of the elastic sealing cap 42, and the annular sealing portion 422 abuts against the water outlet tray 3 and surrounds the connecting hole 31 to seal the connecting hole 31. In this way, when the shower head is turned on, the water flow of the connecting hole 31 can exert pressure on the recessed portion 421, thereby easily deforming the elastic sealing cap 42 and opening the connecting hole 31.

[0042] In one embodiment, the support structure 52 has a central cavity 523 , and when the elastic sealing cap 42 is pressurized by water in the connecting hole 31 , the elastic sealing cap 42 deforms toward the central cavity 523 , that is, the support structure 52 allows the elastic sealing cap 42 to have a deformable space.

[0043] like Fig.11 and Fig.12 As shown, the support structure 52 includes support ribs arranged around the central cavity 523, and the support ribs are provided with a communication opening 524 that connects the central cavity 523 to the outside. By setting the central cavity 523 to be connected to the outside, the central cavity 523 is ventilated, and the elastic sealing cap 42 can be prevented from being adsorbed by the central cavity 523. Fig.12 It is shown in the figure that the central cavity 523 is connected to the water outlet hole 51 on the cover 5 through the connecting opening 524 to achieve ventilation of the central cavity 523.

[0044] In one example, the support structure 52 cooperates with the elastic sealing cap 42 as shown in FIG. Figure 3As shown, in this example, a recessed portion 421 and an annular sealing portion 422 surrounding the recessed portion 421 are formed at the top of the elastic sealing cap 42, and the annular sealing portion 422 surrounds the connecting hole 31 and abuts against the water outlet tray 3 to achieve sealing of the connecting hole 31; the elastic sealing cap 42 has a sealing cap cavity 43 with an opening toward the surface cover, and since the elastic sealing cap 42 is recessed on the side of the water outlet sleeve 4 facing the surface cover 5 to form a convex bulge protruding toward the water outlet cover 3, a sealing cap cavity 43 with an opening toward the surface cover 5 is formed inside the elastic sealing cap 42, the recessed portion 421 at the top of the elastic sealing cap 42 forms a convex portion protruding toward the sealing cap cavity 43, and the annular sealing portion 422 forms an annular recessed portion 431 surrounding the convex portion in the sealing cap cavity 43. The support structure 52 includes a support rib protruding toward the sealing cap cavity 43, and the support rib is arranged around to form a central cavity 523 located at the center. The support rib includes a first rib portion 521 and a second rib portion 522 located above the first rib portion 521, and the second rib portion 522 corresponds to the annular recess 431, wherein the width of the second rib portion 522 in the radial direction is greater than the width of the first rib portion 521, and the second rib portion 522 being located above the first rib portion 521 means that the second rib portion 522 is away from the main body of the face cover 5 relative to the first rib portion 521, and the second rib portion 522 corresponding to the annular recess 431 means that the two positions correspond in the direction away from the face cover 5. Since the annular recess 431 is narrow at the top and wide at the bottom, a narrower second rib portion 522 is provided, so that when the sealing cap 43 is deformed toward the central cavity of the support structure by water pressure, the second rib portion 522 can easily enter the annular recess 431.

[0045] It can be understood that the structure of the elastic sealing cap 42 may not be limited to the structure described above, as long as it can be deformed under the action of water pressure to make the connecting hole 31 connected. The structure of the supporting structure 52 is also not limited to the structure described above. For example, the supporting structure 52 can also be in the form of a spring or an elastic sheet. After the elastic sealing cap 42 is deformed by the water pressure and supported on the supporting structure 52, the spring or elastic sheet is also deformed. When the shower is turned off, the elastic sealing cap 42 can immediately bounce up to stop water under the action of its own elasticity and the elasticity of the supporting structure 52.

[0046] In one embodiment, the shower head further includes a sealing plate 2, and a first water chamber 20 is formed between the sealing plate 2 and the water outlet plate 3. The first water chamber 20 includes a central water chamber 201 located at the center of the water outlet plate 3 and a plurality of first water chambers 202 connected to the central water chamber 201 and arranged circumferentially, and a plurality of connecting holes 31 are divided into a plurality of groups, and each first water chamber 301 corresponds to a group of connecting holes 31. The central water chamber 201 is connected to a water inlet hole 23 located at the center of the water outlet plate 3, and the water supply of the shower head enters the central water chamber 201 from the water inlet hole 23, and then is dispersed to each first water chamber 202, so that the water output of the connecting holes 31 can be uniform.

[0047] like Figure 6 As shown, in order to form a first water cavity 20 between the sealing disk 2 and the water outlet disk 3, a first water barrier 21 is provided on the surface of the sealing disk 2 facing the water outlet disk 3, and the first water barrier 21 abuts against the water outlet disk 3, thereby forming a central water cavity 201 and a plurality of first water dividing cavities 202 between the sealing disk 2 and the water outlet disk 3.

[0048] Figure 6 In the example shown, the first water diversion chamber 202 includes a plurality of communicating hole regions and a channel connecting two adjacent communicating hole regions, wherein the plurality of communicating hole regions correspond one-to-one to the plurality of communicating holes in a group of communicating holes 31 . Figure 6 The diagram shows five communicating hole regions a, b, c, d, and e in a first water diversion chamber 202. The five communicating hole regions correspond one-to-one to five communicating holes in a group of communicating holes 31, respectively. Adjacent communicating hole regions are connected through channels. This water chamber partitioning method allows long channels to be set between the communicating hole regions to achieve water connectivity. Thus, the first water diversion chamber can be made as small as possible when corresponding to a group of communicating holes with the same number. Therefore, when the shower is turned off, the residual water left in each first water diversion chamber is as small as possible, which is conducive to achieving rapid water stopping.

[0049] In one embodiment, the sealing plate 2, the water outlet plate 3, the water outlet sleeve 4 and the surface cover 5 are fixed together by bolts 11. Figure 4-11 As shown, the sealing plate 2 is provided with a plurality of bolt holes 22, the water outlet plate 3 is provided with a plurality of first through holes 33, the water outlet sleeve 4 is provided with a plurality of second through holes 44, and the side of the surface cover 5 facing the water outlet sleeve 4 is provided with a plurality of bolt fixing columns 53, and the plurality of bolts 11 respectively pass through the bolt holes 22 on the sealing plate 2, the first through holes 33 on the water outlet plate 3 and the second through holes 44 on the water outlet sleeve 4 in sequence, and then are fixed to the bolt fixing columns 53 on the surface cover 5, thereby fixing the sealing plate 2, the water outlet plate 3, the water outlet sleeve 4 and the surface cover 5 together.

[0050] In one embodiment, a second water chamber 30 is formed between the water outlet tray 3 and the water outlet sleeve 4. The second water chamber 30 includes a plurality of second water sub-cavities. The plurality of second water sub-cavities are connected to a plurality of connecting holes 31 one by one. Each second water sub-cavity is connected to a group of water outlet nozzles 41. To form the second water chamber 30, as shown in FIG. Figure 7 and Figure 8 As shown, a second water barrier 32 is provided on the surface of the water outlet tray 3 on one side facing the water outlet sleeve 4. The second water barrier 32 abuts against the water outlet sleeve 4 to divide the space between the water outlet tray 3 and the water outlet sleeve 4 to form a plurality of second water diversion chambers. Each second water diversion chamber is connected to a corresponding connecting hole 31, so that the water supply of each connecting hole 31 flows to the corresponding second water diversion chamber, and then the second water diversion chamber supplies water to a corresponding group of water outlet nozzles 41, thereby ensuring that the water output of each water outlet nozzle 41 is uniform.

[0051] Figure 7 and Figure 8 In the example shown, each second water diversion chamber includes a central area 301 corresponding to a connecting hole 31, a plurality of water outlet areas 302, and a channel 303 connecting the plurality of water outlet areas 302 to the central area 301, wherein the plurality of water outlet areas 302 correspond one-to-one to a plurality of water outlets 41 in a group of water outlets 41, wherein the central area 301 may be a substantially circular area surrounding the connecting hole 31, the water outlet area 302 may be a substantially circular area surrounding the hole on the water outlet 41, and the channel 303 may be set to have a width smaller than the diameter of the water outlet area 302. The setting method of the second water diversion chamber can make the second water diversion chamber as small as possible when corresponding to a group of water outlets with the same number, so that the residual water in the second water diversion chamber is as small as possible when the shower is turned off, thereby facilitating rapid water stopping.

[0052] In one embodiment, if Figure 1-Figure 5 As shown, the shower head also includes a shower body 1 and a ball head assembly with a water inlet end. The shower body 1 and the face cover 5 form a cavity. The sealing plate 2, the water outlet plate 3, and the water outlet sleeve 4 are all located in the cavity between the shower body 1 and the face cover 5.

[0053] Figure 2In the example shown, the ball head assembly includes a connecting sleeve 7 and a ball head 6 which is limited in the connecting sleeve 7 by a ball head sleeve 8, and the ball head 6 has a water inlet end, wherein the shower body 1 is sleeved on the central connecting portion 23 of the sealing disc 2, and the connecting sleeve 7 is threadedly connected to the central connecting portion 23 of the sealing disc 2 and abuts against the shower body 1, so that the shower body 1 and the cover 5 are matched and fixed together. A gasket 10 is provided between the ball head 6 and the central connecting portion 23, and a sealing ring 9 is provided between the ball head 6, the gasket 10 and the central connecting portion 23, so as to prevent the water supply of the shower from leaking from the ball head assembly. The water entering from the water inlet end of the ball head 6 can enter the first water chamber 20 through the water inlet hole 231 of the central connecting portion 23 of the sealing disk 2, and then dispersed from the central water chamber 201 of the first water chamber 20 to each first water diversion chamber 202, and the water in each first water diversion chamber 202 flows to each second water diversion chamber of the second water chamber 30 through a group of connecting holes 31, and then the water in each second water diversion chamber is sprayed out from each water outlet nozzle 41.
