Water outlet structure, shower head

[0001] This disclosure claims priority to Chinese patent applications filed on April 23, 2024, with application number 202410494422.2 entitled "Water Outlet Structure, Shower Head" and application number 202420854264.2 entitled "Water Outlet Structure, Shower Head", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to a water outlet structure and a shower head. Background Technology

[0003] Most existing showerheads are made of rigid materials, and the nozzles do not adapt to water pressure. As a result, existing showerheads have little or no water pressure when the water is low, while the water pressure is too great when the water is high, which affects the showering experience. Summary of the Invention

[0004] The spout structure and shower head disclosed herein can improve the showering experience.

[0005] According to a first aspect of this disclosure, a spout structure is provided, comprising:

[0006] The water outlet body has a flow channel inside, which is used to transport spray water.

[0007] The water outlet is located at the end of the water outlet body. The water outlet is provided with a first pressure through hole and a second pressure outlet. The first pressure through hole is connected to the flow channel and the second pressure outlet respectively. According to the pressure of the spray water, the first pressure through hole and the second pressure outlet are configured to adjust the corresponding opening degree.

[0008] According to one embodiment of this disclosure, the length of the second pressure outlet along the first direction is greater than the width of the second pressure outlet along the second direction;

[0009] Wherein, the first direction is the extension direction of the water outlet end, and the first direction, the second direction and the water outlet direction of the first pressure through hole are perpendicular to each other.

[0010] According to one embodiment of the present disclosure, a plurality of second pressure outlets are disposed on at least one side of the first pressure through hole along the first direction;

[0011] And / or, a plurality of the second pressure outlets are disposed on at least one side of the first pressure through hole along the second direction.

[0012] According to one embodiment of this disclosure, a plurality of second pressure outlets are distributed along the circumferential direction of the first pressure through hole.

[0013] According to one embodiment of this disclosure, along the first direction and toward a direction away from the first pressure through hole, the width of the second pressure outlet gradually decreases along the second direction;

[0014] And / or, along the second direction and toward a direction away from the first pressure through-hole, the width of the second pressure outlet gradually decreases along the first direction.

[0015] According to one embodiment of this disclosure, along the first direction, the ratio of the length of the second pressure outlet to the length of the outlet end is greater than 1 / 3.

[0016] According to one embodiment of the present disclosure, the sidewalls of the second pressure outlet located on at least one side of the first pressure through hole along the first direction are in contact with each other along the second direction;

[0017] And / or, the sidewalls of the second pressure outlet located on at least one side of the first pressure through hole along the second direction are in contact with each other along the first direction.

[0018] According to one embodiment of this disclosure, the sidewall of the second pressure outlet located on at least one side of the first pressure through hole along the first direction is at least one of a straight line, a wavy line, or a broken line;

[0019] And / or, the sidewall of the second pressure outlet located on at least one side of the first pressure through hole along the second direction is a straight line, a wavy line, or a broken line.

[0020] According to one embodiment of this disclosure, the second pressure outlet is disposed along the edge of the first pressure through hole at one end near the first pressure through hole.

[0021] According to one embodiment of this disclosure, the end of the second pressure outlet near the first pressure through hole is flush with the edge of the outlet end.

[0022] According to one embodiment of this disclosure, a notch is provided on the peripheral side of the water outlet body, and the notch is correspondingly provided with and connected to the second pressure water outlet.

[0023] According to one embodiment of this disclosure, the shape of the first pressure through-hole is at least one of a circle, an ellipse, an oblong hole, or a polygon.

[0024] According to one embodiment of this disclosure, the water outlet is made of an elastic material.

[0025] According to one embodiment of this disclosure, the thickness of the water outlet end along the water flow direction of the first pressure through hole is less than the wall thickness of the water outlet body.

[0026] According to one embodiment of this disclosure, the spout body and the spout end are integrally formed.

[0027] According to a second aspect of this disclosure, embodiments of this disclosure also provide a shower head, including a shower head body, a faceplate, and a spout structure as described above passing through the faceplate.

[0028] According to one embodiment of this disclosure, the shower head further includes:

[0029] A water distribution component is disposed between the shower head body and the face cover, and the water distribution component is provided with a drain hole;

[0030] A spindle is disposed within the shower head body, and a siphon chamber is disposed within the spindle. The drain hole is connected to the water outlet structure and the siphon chamber.

[0031] A drain valve is located at the end of the siphon chamber away from the outlet structure, and is used to drain residual water in the siphon chamber.

[0032] One embodiment of this disclosure has the following advantages or beneficial effects:

[0033] The water outlet structure and shower head provided in this embodiment have the following characteristics: Under low water pressure, the opening of the second pressure outlet is approximately zero or relatively small. The spray water flowing out of the flow channel is sprayed or discharged through the first pressure through hole. The first pressure through hole ensures that the water outlet structure still has a certain water outlet area under low water pressure, guaranteeing the water output effect. Moreover, due to the small water outlet area, the water output still has an impact force. Under high water pressure, the opening of the first pressure through hole and the second pressure outlet gradually increases with the spray water pressure. The spray water flowing out of the flow channel is sprayed or discharged simultaneously through the first pressure through hole and the second pressure outlet. The water outlet area is the sum of the area of ​​the first pressure through hole and the opening area of ​​the second pressure outlet. Due to the relatively large water outlet area, it does not cause a large impact force, thus improving the showering experience.

[0034] Because the opening degree of the first pressure through hole and the second pressure outlet is adjusted according to the pressure of the sprayed water, the degree of expansion or opening of the first pressure through hole and the second pressure outlet will also change accordingly, which has the effect of automatic pressure sensing. This allows the outlet end to adapt to the deformation of the sprayed water pressure, and the overall water outlet area also changes with the pressure of the sprayed water, thereby changing the water output and spray intensity.

[0070] Most existing showerheads are made of rigid materials, and the nozzles do not adapt to water pressure. As a result, existing showerheads have little or no water pressure when the water is low, while the water pressure is too great when the water is high, which affects the showering experience.

[0071] To address this issue, as shown in Figures 1-8, this embodiment provides a water outlet structure 100. The water outlet structure 100 includes a water outlet body 1 and a water outlet end 2. A flow channel 11 is provided within the water outlet body 1, and the water outlet end 2 is located at the end of the water outlet body 1. The flow channel 11 within the water outlet body 1 is used to temporarily store and transport spray water, which is ultimately sprayed or discharged from the water outlet end 2.

[0072] The water outlet 2 can be installed at the end of the water outlet body 1 by means of bolts, snap-fit, welding, etc. For example, the water outlet body 1 has a structure with two open ends. One of the open ends of the water outlet body 1 is used to receive spray water, and the water outlet 2 is similar to a flat plate or a plug head structure, used to block the other open end of the water outlet body 1.

[0073] The water outlet 2 can also be integrally formed with the water outlet body 1 to reduce the time for parts assembly. In this embodiment, the specific connection method between the water outlet 2 and the water outlet body 1 is not limited and can be adjusted according to the actual production situation.

[0074] In one embodiment, the spout body 1 is provided with a guide slope 12. The number of guide slopes 12 can be one or two. The two guide slopes 12 are provided on both sides of the spout body 1. In this case, the spout body 1 is approximately duckbill shaped.

[0075] The flow channel 11 is at least partially conical in shape, with the smaller end of the conical structure facing the water outlet 2, so that the spray water in the flow channel 11 can be concentrated towards the water outlet 2, making it easier for the water outlet 2 to discharge water.

[0076] Specifically, the water outlet 2 is provided with a first pressure through hole 21 and a second pressure outlet 22. The first pressure through hole 21 is connected to the flow channel 11 and the second pressure outlet 22 respectively. That is, the flow channel 11 is connected to the first pressure through hole 21 and the second pressure outlet 22. According to the pressure of the spray water, the first pressure through hole 21 and the second pressure outlet 22 are configured to adjust the corresponding opening degree.

[0077] Under low water pressure, the opening of the second pressure outlet 22 is approximately zero or relatively small. The spray water flowing out of the flow channel 11 is sprayed or discharged through the first pressure through hole 21. Under the action of the first pressure through hole 21, the nozzle structure 100 can still have a certain water outlet area under low water pressure, ensuring the water outlet effect. Moreover, due to the small water outlet area, the water outlet still has an impact force. Under high water pressure, the opening of the first pressure through hole 21 and the second pressure outlet 22 gradually increases with the spray water pressure. The spray water flowing out of the flow channel 11 is sprayed or discharged simultaneously through the first pressure through hole 21 and the second pressure outlet 22. The water outlet area is the sum of the area of ​​the first pressure through hole 21 and the opening area of ​​the second pressure outlet 22. Since the water outlet area of ​​the nozzle structure 100 is relatively large, it will not cause a large impact force, thus improving the shower experience.

[0078] According to the pressure of the spray water, the opening degree of the first pressure through hole 21 and the second pressure outlet 22 is adjusted accordingly. That is, the degree of expansion or opening of the first pressure through hole 21 and the second pressure outlet 22 will also change accordingly, which has an automatic pressure sensing effect, so that the outlet end 2 can adapt to the deformation of the spray water pressure. The overall water outlet area also changes with the pressure of the spray water, thereby changing the water output and spray intensity.

[0079] In one embodiment, the water outlet 2 is made of an elastic material.

[0080] Because the water outlet 2 is made of elastic material, it can produce a certain elastic deformation. When the water pressure of the spray water is relatively low, the first pressure through hole 21 and the second pressure outlet 22 hardly deform, and the spray water can only be sprayed or discharged through the first pressure through hole 21. When the water pressure of the spray water is relatively high, the first pressure through hole 21 and the second pressure outlet 22 will deform, and the spray water will be sprayed or discharged through the first pressure through hole 21 and the second pressure outlet 22. The elastic water outlet 2 can quickly open the second pressure outlet 22 when the water pressure is high.

[0081] In one embodiment, the thickness of the outlet end 2 along the water flow direction of the first pressure through hole 21 is less than the wall thickness of the outlet body 1. With this configuration, the outlet end 2 is thinner, has lower structural strength, and is more prone to deformation, which facilitates the rapid opening of the second pressure outlet 22.

[0082] Specifically, the shape of the first pressure through hole 21 is at least one of the following: circular (as shown in Figures 1-8), elliptical (as shown in Figures 9-10), oblong, or polygonal. Among them, the polygonal shape includes, but is not limited to, triangle, rectangle, square, trapezoid, etc.

[0083] For example, when the first pressure through hole 21 is circular, if the pressure of the spray water is relatively small, the shape of the first pressure through hole 21 can remain unchanged, and the water outlet area of ​​the water outlet 2 is the same as the area of ​​the initial first pressure through hole 21. If the pressure of the spray water is relatively large, the shape of the first pressure through hole 21 can remain approximately unchanged, except that the diameter of the first pressure through hole 21 increases. Alternatively, the shape of the first pressure through hole 21 can change. For example, as the opening of the first pressure through hole 21 gradually increases, the shape of the first pressure through hole 21 gradually becomes an elliptical structure.

[0084] In one embodiment, the second pressure outlet 22 is positioned along the edge of the first pressure through hole 21 at one end near the first pressure through hole 21. In this manner, the edges of the second pressure outlet 22 and the first pressure through hole 21 are in direct contact, and the first pressure through hole 21 and the second pressure outlet 22 form a continuous structure, facilitating direct communication between them. As the spray water pressure gradually increases, the first pressure through hole 21 expands and continues to expand further along the second pressure outlet 22, increasing the water outlet area.

[0085] It should be noted that the cross-section of the water outlet 2 is similar to a rectangular structure. The length direction of the water outlet 2 is defined as the first direction, which is the extension direction of the water outlet 2. The first direction is identified by D1. The width direction of the water outlet 2 is the second direction, which is identified by D2. The thickness direction of the water outlet 2 is the third direction, which is the water outlet direction of the water outlet 2. The third direction is identified by D3. The first direction, the second direction, and the third direction are all perpendicular to each other. The first direction, the second direction, and the third direction only represent spatial directions and have no substantial meaning.

[0086] In one embodiment, as shown in Figures 1-8, the length of the second pressure outlet 22 along the first direction is greater than the width of the second pressure outlet 22 along the second direction.

[0087] That is, the second pressure outlet 22 is similar to a long strip structure. Under different spray water pressures, the second pressure outlet 22 will adapt to the water pressure and deform accordingly. The degree of expansion or opening of the second pressure outlet 22 will change accordingly, so that the water outlet area of ​​the second pressure outlet 22 changes with the water pressure. This can change the amount of water output or the spray intensity of the second pressure outlet 22.

[0088] In one embodiment, as shown in Figures 1-10, a plurality of second pressure outlets 22 are disposed on at least one side of the first pressure through hole 21 along a first direction.

[0089] For example, two second pressure outlets 22 are disposed on both sides of the first pressure through hole 21 along the first direction. When the water pressure of the spray water is relatively high, the expansion or widening direction of the second pressure outlets 22 is also along the first direction, so that the opening of the second pressure outlets 22 can have a large adjustment range. For example, when the spray water passes through the first pressure through hole 21 and enters the second pressure outlets 22, after the second pressure outlets 22 expand along the first direction, the first pressure through hole 21 and the second pressure outlets 22 can form an elliptical structure, and the major axis of the elliptical structure is arranged parallel to the first direction.

[0090] In one embodiment, the sidewalls of the second pressure outlet 22 located on at least one side of the first pressure through hole 21 along the first direction are in contact with each other along the second direction.

[0091] That is, the width of the second pressure outlet 22 along the second direction is approximately zero. In actual production, a narrow slit or cut can be made at the corresponding position of the outlet end 2 to form the second pressure outlet 22. The structure is simple and the production cost is relatively low. At the same time, when the initial state or the spray water pressure is relatively low, the side walls of the second pressure outlet 22 arranged opposite each other along the second direction are in contact with each other, and the second pressure outlet 22 is in a completely closed state.

[0092] In one embodiment, as shown in Figures 1-11, the sidewall of the second pressure outlet 22 located on at least one side of the first pressure through hole 21 along the first direction is at least one of a straight line, a wavy line, or a broken line.

[0093] For example, as shown in Figures 1-10, when the sidewall of the second pressure outlet 22 is straight along the second direction, the second pressure outlet 22 is similar to a straight-line structure. The processing technology is simple, the production cost is relatively low, and the sidewall edge of the straight structure is relatively smooth, which reduces the risk of scale and other impurities remaining and facilitates the discharge of scale and other impurities.

[0094] In this method, when the spray water pressure is low, only the circular first pressure through-hole 21 emits water, and the outlet area is small. When the spray water pressure is high, because two slit-structured second pressure outlets 22 are provided on both sides of the first pressure through-hole 21, the circular first pressure through-hole 21 gradually transforms into an ellipse under high pressure, and the outlet area increases. Consequently, the spray force at the outlet end 2 does not increase significantly with increasing pressure. By setting the circular first pressure through-hole 21 and providing two second pressure outlets 22 on both sides of the first pressure through-hole 21, the outlet end 2 is easily deformed and enlarged under high pressure. It can automatically sense the water pressure and automatically adjust the shape and outlet area of ​​the outlet end 2 accordingly, which is also beneficial for the discharge of particulate impurities.

[0095] For example, as shown in Figure 11, when the sidewalls of the second pressure outlet 22 arranged opposite each other along the second direction are wavy lines or zigzag lines, the two sidewalls of the second pressure outlet 22 arranged opposite each other along the second direction have a nested structure, ensuring the reliability of the second pressure outlet 22 closing when the spray water pressure is relatively low. Specifically, the protrusion of one sidewall of the first pressure through hole 21 along the second direction is inserted into the groove of the other sidewall. When the spray water sprays along the third direction, the protrusion can block the spray water to a certain extent, reduce the impact force of the spray water, and further improve the shower experience.

[0096] In one embodiment, as shown in Figures 1-8, the ratio of the length of the second pressure outlet 22 to the length of the outlet end 2 along the first direction is greater than 1 / 3.

[0097] If the length of the second pressure outlet 22 along the first direction is relatively short, the second pressure outlet 22 can only open suddenly when the water pressure of the spray water reaches a very high level. In this case, the spray water output force changes significantly with the water pressure. By setting the ratio of the length of the second pressure outlet 22 to the length of the outlet end 2 to be greater than 1 / 3, the length of the second pressure outlet 22 is relatively long. This makes it easier to open when the water pressure of the spray water is relatively low. The opening time of the second pressure outlet 22 is earlier and the continuity of the opening is good. The opening degree of the second pressure outlet 22 changes with the water pressure of the spray water. The opening degree of the second pressure outlet 22 is gradual, so that the spray water output force does not increase significantly with the increase of water pressure, thus improving the uniformity of the spray water impact.

[0098] In one embodiment, as shown in FIG12, the end of the second pressure outlet 22 near the first pressure through hole 21 is flush with the edge of the outlet end 2.

[0099] In this manner, one end of the second pressure outlet 22 extends to the first pressure through hole 21, and the other end extends to the edge of the outlet end 2, maximizing the length range of the second pressure outlet 22. This allows the first pressure through hole 21 and the second pressure outlet 22 to cover the entire length range of the outlet end 2 along the first direction. When the spray water pressure is relatively low, the second pressure outlet 22 is easily opened, and when the spray water pressure is relatively high, the water outlet area of ​​the second pressure outlet 22 is relatively large, reducing the force of the spray water and thus reducing the difference between high and low pressure spray water.

[0100] In one embodiment, as shown in FIG13, a notch 13 is provided on the peripheral side of the water outlet body 1, and the notch 13 is correspondingly provided with and connected to the second pressure water outlet 22.

[0101] By extending the length of the second pressure outlet 22 along the edge of the outlet end 2, the overall length of the second pressure outlet 22 is increased. This makes it easier for the outlet to deform under higher spray water pressure, facilitating adaptive deformation with changes in spray water pressure and promoting the self-adaptation of the outlet end 2. Simultaneously, it facilitates the removal of scale and other impurities.

[0102] In one embodiment, as shown in FIG14, the width of the second pressure outlet 22 gradually decreases along the second direction in the direction away from the first pressure through-hole 21.

[0103] That is, the width of the second pressure outlet 22 along the second direction is not uniform, but is a variable width structure. The farther the distance between the second pressure outlet 22 and the first pressure through hole 21, the smaller the width along the second direction at that position. As the spray water pressure gradually increases, the opening of the second pressure outlet 22 gradually increases as it gradually opens, and the water outlet area of ​​the second pressure outlet 22 also becomes larger. That is, when the area of ​​the water outlet remains unchanged, a larger spray water pressure corresponds to a larger water outlet area, further improving the uniformity of the spray water outlet.

[0104] In one embodiment, as shown in FIG15, a plurality of second pressure outlets 22 are disposed on both sides of the first pressure through hole 21 along the second direction.

[0105] For example, two second pressure outlets 22 are disposed on both sides of the first pressure through hole 21 along the second direction. When the water pressure of the spray water is relatively high, the expansion or widening direction of the second pressure outlets 22 is also along the second direction. Since the width of the outlet end 2 along the second direction is relatively small, the opening of the second pressure outlets 22 can be limited within a certain range, avoiding the risk of tearing or difficulty in repositioning after the outlet end 2 undergoes large deformation. For example, when the spray water passes through the first pressure through hole 21 and enters the second pressure outlet 22, after the second pressure outlet 22 expands along the second direction, the first pressure through hole 21 and the second pressure outlet 22 can form an elliptical structure, with the major axis of the elliptical structure parallel to the second direction.

[0106] In one embodiment, as shown in FIG16, a plurality of second pressure outlets 22 are distributed along the circumferential direction of the first pressure through hole 21.

[0107] For example, four second pressure outlets 22 are evenly distributed along the circumferential direction of the first pressure through-hole 21, with an included angle of 90° between two adjacent second pressure outlets 22. In this way, the four second pressure outlets 22 form a cross-shaped structure. By using this method, when the water pressure of the spray water is relatively high, the water outlet area of ​​the outlet end 2 can be further increased to reduce the high-pressure impact force.

[0108] Of course, in some embodiments, the multiple second pressure outlets 22 may be unevenly distributed along the circumferential direction of the first pressure through hole 21, or only some of the second pressure outlets 22 may be arranged along the first or second direction. In this case, the multiple second pressure outlets 22 are arranged radially around the first pressure through hole 21. Similarly, the opening of the second pressure outlets 22 can be automatically adjusted according to the water pressure of the spray water.

[0109] In one embodiment, as shown in Figures 15-16, the sidewalls of the second pressure outlet 22 located on at least one side of the first pressure through hole 21 along the second direction are in contact with each other along the opposite sidewalls of the first pressure outlet 22 along the first direction.

[0110] That is, the width of the second pressure outlet 22 along the first direction is approximately zero. In actual manufacturing, a slit or cut can be made on at least one side of the outlet end 2 along the second direction to form the second pressure outlet 22. The structure is simple and the production cost is relatively low. At the same time, when the initial state or the spray water pressure is relatively low, the side walls of the second pressure outlet 22 arranged opposite each other along the first direction are in contact with each other, and the second pressure outlet 22 is in a completely closed state.

[0111] In one embodiment, the sidewall of the second pressure outlet 22 located on at least one side of the first pressure through hole 21 along the second direction is at least one of a straight line, a wavy line, or a broken line.

[0112] For example, when the sidewall of the second pressure outlet 22 is straight along the first direction, the second pressure outlet 22 is similar to a straight line structure. The processing technology is simple, the production cost is relatively low, and the sidewall edge of the straight structure is relatively smooth, which reduces the risk of scale and other impurities remaining and facilitates the discharge of scale and other impurities.

[0113] For example, when the sidewalls of the second pressure outlet 22 arranged opposite each other along the first direction are wavy or zigzag, the two sidewalls of the second pressure outlet 22 arranged opposite each other along the first direction are nested, ensuring the reliability of the second pressure outlet 22 closing when the spray water pressure is relatively low. Specifically, the protrusion of one sidewall of the first pressure through hole 21 along the first direction is inserted into the groove of the other sidewall. When the spray water sprays along the third direction, the protrusion can block the spray water to a certain extent, reduce the impact force of the spray water, and further improve the shower experience.

[0114] In one embodiment, along the second direction and toward the direction away from the first pressure through-hole 21, the width of the second pressure outlet 22 gradually decreases along the first direction.

[0115] That is, the width of the second pressure outlet 22 along the first direction is not completely uniform, but is a variable width structure. The farther the distance between the second pressure outlet 22 and the first pressure through hole 21, the smaller the width along the first direction at that position. As the spray water pressure gradually increases, the opening of the second pressure outlet 22 gradually increases as it gradually opens, and the water outlet area of ​​the second pressure outlet 22 also becomes larger. That is, when the water outlet area remains unchanged, a larger spray water pressure corresponds to a larger water outlet area, further improving the uniformity of the spray water outlet.

[0116] This embodiment also provides a shower head, as shown in Figures 17-21. The shower head includes a shower head body 200, a water distribution component 300, a faceplate 400, and the aforementioned water outlet structure 100. The water distribution component 300 is disposed between the shower head body 200 and the faceplate 400, and the water outlet structure 100 passes through the faceplate 400.

[0117] The shower head provided in this embodiment has a shower head body 200 that serves to accommodate and support the shower head, and a water distribution component 300 that serves to distribute water, thereby increasing the number of spray modes and providing an installation position for the water outlet structure 100. The face cover 400 serves to cover the shower head, improving its aesthetics, and the water outlet end 2 of the water outlet structure 100 can extend from the face cover 400 for easy cleaning.

[0118] The spout structure 100 also includes a mounting part 3 (as shown in Figures 1 and 5). The mounting part 3 is located at the end of the spout body 1 away from the outlet end 2, that is, the mounting part 3 is arranged around the top of the spout body 1. The mounting part 3 can be connected to the water distribution component 300 by means of detachable connection such as bolt connection or snap-fit, or it can be fixed to the water distribution component 300 by welding. The mounting part 3 and the spout body 1 can be integrally formed, reducing parts assembly time and production costs.

[0119] In one embodiment, as shown in Figures 21-24, the shower head further includes a fixed base 700 and a control intermittent structure 800. The fixed base 700 is disposed within the shower head body 200, providing an installation or rotatable connection position for the intermittent structure. Specifically, the intermittent structure includes a button 801, a first pin 802, a second pin 803, a third pin 804, a rocker arm 8040, a first return spring 805, a slider 806, a rotating block 807, a pawl 808, and a ratchet 809. One end of the button 801 is rotatably connected to the fixed base 700 via the first pin 802, and the other end abuts against the rocker arm 8040. The rocker arm 8040 is rotatably connected to the fixed base 700 via the second pin 803. A first return spring 805 is disposed between the slider 806 and the fixed base 700. One end of the slider 806 abuts against the end of the rocker arm 8040 away from the button 801, and the other end of the slider 806 abuts against the pawl 808. The pawl 808 is rotatably connected to the fixed seat 700 via the third pin 804. The ratchet 809 is located inside the pawl 808 and sleeved on the outside of the rotating block 807. A second spring 810 is provided between the rotating block 807 and the fixed seat 700.

[0120] Pressing button 801 causes it to rotate around the first pivot 802, driving the rocker arm 8040 to rotate around the second pivot 803. The rocker arm 8040 then drives the slider 806 to move closer to the pawl 808 and compress the first return spring 805. The first return spring 805 stores energy, and the slider 806 drives the pawl 808 to rotate around the third pivot 804. The pawl 808 drives the ratchet 809 to rotate counterclockwise by one ratchet angle. When button 801 is released, the first return spring 805 resets, causing the pawl 808, rocker arm 8040, and button 801 to return to their initial positions. The ratchet 809 is then fixed in the switched position by the stop pawl 8091, thus achieving a function switch.

[0121] Specifically, as shown in Figure 21, the water distribution component 300 is disposed between the fixed base 700 and the cover 400. The water distribution component 300 includes a water distribution plate 301, a water distribution body 302, and a water distribution seat 303. A sealing gasket 304 is disposed between the water distribution plate 301 and the water distribution body 302. The rotating block 807, the water distribution plate 301, and the ratchet 809 are fixedly connected, so the water distribution plate 301 can rotate synchronously with the ratchet 809. The water distribution plate 301 is provided with four water inlet holes, and the water distribution body 302 is provided with six water outlet holes 305 (as shown in Figure 25), thus realizing three functions of intermittent water output. How the intermittent water output is specifically implemented is not the main inventive point of this disclosure, so it will not be described in detail.

[0122] In one embodiment, the shower head further includes a sealing ring 900 and an aerator 1000. The aerator 1000 is disposed between the water distribution base 303 and the faceplate 400 for generating foam to improve the user's showering experience. The sealing ring 900 is disposed between the aerator 1000 and the water distribution body 302 to ensure the sealing effect of the aerator 1000.

[0123] Because after the water is turned off, the first pressure through hole 21 of the water outlet 2 will return to a small circular hole. When the shower head is hung on the socket, due to the large tilt angle of the shower head, the residual water takes a very long time to be discharged from the first pressure through hole 21. If you are away from home for a long time, bacteria will grow in the shower head.

[0124] To solve this problem, as shown in Figures 25-31, the shower head also includes a spindle 500 and a drain valve 600. The spindle 500 is disposed inside the shower head body 200, and a siphon chamber 501 is disposed inside the spindle 500. The water distribution assembly 300 is provided with a drain hole 305, which is connected to the water outlet structure 100 and the siphon chamber 501. The drain valve 600 is disposed at the end of the siphon chamber 501 away from the water outlet structure 100, and is used to drain the residual water in the siphon chamber 501.

[0125] Since the drain hole 305 and the siphon chamber 501 are connected, as the spray water is discharged, the siphon chamber 501 gradually becomes a vacuum chamber and generates negative pressure. Under the action of atmospheric pressure, the spray water is forced through the drain hole 305 into the siphon chamber 501, creating a siphon effect. This causes the residual water in the drain hole 305 to be drawn into the siphon chamber 501. Then, the residual water is quickly discharged through the drain valve 600. The drain valve 600 can discharge all the spray water in as little as 5 seconds, so the drain valve 600 can also be called a quick-drain valve. The shower head provided in this disclosure, by setting the drain valve 600 in the shower head body 200, can quickly drain the residual water in the shower head body 200, preventing residual water from dripping onto the wiped body, and at the same time reducing the situation where bacteria can easily grow when you are away from home for a long time.

[0126] In one embodiment, as shown in Figures 25-31, the discharge valve 600 includes a valve seat 601, a valve core 602, an elastic element 603, and a valve body 604. The valve seat 601 is installed at the end of the siphon chamber 501 away from the outlet structure 100, i.e., at the end of the shower body 200. The valve seat 601 is provided with a quick discharge hole 6011. A valve cavity is formed between the valve seat 601 and the valve body 604. The valve core 602 and the elastic element 603 are disposed in the valve cavity. The elastic element 603 is disposed between the valve core 602 and the valve body 604. The elastic element 603 may be a spring. The valve core 602 is used to selectively block the quick discharge hole 6011.

[0127] When the water is flowing, the spray water passes through the inlet hole of the valve body 604 or the gap between the valve body 604 and the siphon chamber 501 into the valve cavity. The valve core 602 overcomes the elastic force of the elastic element 603 to block the quick-drain hole 6011, allowing water to flow normally. When the water is turned off, the valve core 602 returns to its initial position under the elastic force of the elastic element 603. At this time, the quick-drain hole 6011 is opened, and the residual water at the outlet 2 is quickly discharged to the outside of the shower head along the quick-drain hole 6011 under the siphon effect, preventing residual water from dripping from the shower head's nozzle structure 100 for a long time and reducing the possibility of dripping leakage from the nozzle structure 100.

[0128] In one embodiment, a check valve 1100 is also provided at the bottom of the discharge valve 600 to prevent the backflow of spray water.
