[0076] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0077] The water outlet heads of existing shower heads are mostly made of hard materials, and the water outlet heads will not deform adaptively with the water pressure. Therefore, under low water pressure, the water of the existing shower head has no impact force or has a small impact force, while under high water pressure, the impact force of the water is too large, affecting the shower experience.

[0078] To solve this problem, Figure 1-Figure 8 As shown, this embodiment provides a water spout structure 100, which includes a water spout body 1 and a water outlet end 2. A flow channel 11 is provided in the water spout body 1, and the water outlet end 2 is provided at the end of the water spout body 1. The flow channel 11 in the water spout body 1 is used to temporarily store and transport spray water, and the spray water is finally sprayed or discharged from the water outlet end 2.

[0079] Among them, the water outlet end 2 can be installed on the end of the water outlet body 1 by means of bolts, clamping, welding, etc. For example, the water outlet body 1 is a structure with two openings at both ends, one of the opening ends of the water outlet body 1 is used to receive the spray water, and the water outlet end 2 is similar to a flat plate or a plugging head structure, which is used to seal the other opening end of the water outlet body 1.

[0080] The water outlet end 2 may also be an integrally formed structure with the water outlet body 1 to reduce the time for assembling parts. The present embodiment does not limit the specific connection method between the water outlet end 2 and the water outlet body 1, and it may be adjusted according to actual production conditions.

[0081] In one embodiment, the spout body 1 is provided with a guiding slope 12. The number of the guiding slope 12 can be one or two. The two guiding slopes 12 are provided on both sides of the spout body 1. In this case, the spout body 1 is approximately a duckbill-shaped structure.

[0082] The flow channel 11 is at least partially a conical structure, and the small mouth of the conical structure is arranged toward the water outlet 2, so that the spray water in the flow channel 11 can be concentrated toward the water outlet 2, which is convenient for the water outlet 2 to discharge water.

[0083] Specifically, the water outlet end 2 is provided with a first pressure through hole 21 and a second pressure water outlet 22, and the first pressure through hole 21 is respectively connected with the flow channel 11 and the second pressure water outlet 22, that is, the flow channel 11 is connected with the first pressure through hole 21 and the second pressure water outlet 22, and according to the pressure of the spray water, the first pressure through hole 21 and the second pressure water outlet 22 are configured to adjust the corresponding opening.

[0084] Under low water pressure conditions, the opening of the second pressure water outlet 22 is approximately zero or relatively small, and 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 water outlet structure 100 can still have a certain water outlet area under low water pressure to ensure the water outlet effect, and since the water outlet area is small, the water outlet still has impact force; under high water pressure conditions, the openings of the first pressure through hole 21 and the second pressure water outlet 22 gradually increase with the water pressure of the spray water, and the spray water flowing out of the flow channel 11 is sprayed or discharged through the first pressure through hole 21 and the second pressure water outlet 22 at the same time, and 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 water outlet 22. Since the water outlet area of ​​the water outlet structure 100 is relatively large, it will not cause a large impact force, thereby improving the shower experience.

[0085] According to the pressure of the spray water, the first pressure through hole 21 and the second pressure water outlet 22 adjust the corresponding opening, that is, the expansion degree of the first pressure through hole 21 and the second pressure water outlet 22 will also change accordingly, with an automatic pressure-sensing effect, so that the water outlet end 2 can be adaptively deformed with the pressure of the spray water, and the overall water outlet area also changes with the pressure of the spray water, thereby changing the water output and the water spray intensity.

[0086] In one embodiment, the water outlet end 2 is made of elastic material.

[0087] The water outlet end 2 is made of elastic material, and can produce a certain elastic deformation. When the water pressure of the spray water is relatively small, the first pressure through hole 21 and the second pressure water outlet 22 are almost not deformed, 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 large, the first pressure through hole 21 and the second pressure water outlet 22 will be deformed, and the spray water will be sprayed or discharged through the first pressure through hole 21 and the second pressure water outlet 22. The second pressure water outlet 22 can be quickly opened by using the elastic water outlet end 2 when the water pressure is large.

[0088] In one embodiment, the thickness of the water outlet end 2 along the water flow direction of the first pressure through hole 21 is less than the wall thickness of the water outlet body 1. With this arrangement, the thickness of the water outlet end 2 is thinner, the structural strength is relatively low, and the water outlet end 2 is prone to deformation, which is conducive to the rapid opening of the second pressure water outlet 22.

[0089] Specifically, the shape of the first pressure through hole 21 is circular (eg Figure 1-Figure 8 As shown), elliptical (as Figure 9-10 As shown), at least one of an oblong hole shape, and a polygon, wherein the polygon includes but is not limited to a triangle, a rectangle, a square, a trapezoid, etc.

[0090] For example, when the shape of 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 end 2 is the area size 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, but the diameter of the first pressure through hole 21 becomes larger, and the shape of the first pressure through hole 21 may also 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.

[0091] In one embodiment, one end of the second pressure water outlet 22 close to the first pressure through hole 21 is arranged along the edge of the first pressure through hole 21. In this way, the second pressure water outlet 22 is in direct contact with the edge of the first pressure through hole 21, and the first pressure through hole 21 and the second pressure water outlet 22 are in a continuous structure, which facilitates the direct communication between the second pressure water outlet 22 and the first pressure through hole 21. As the spraying water pressure gradually increases, the first pressure through hole 21 expands and continues to expand further along the second pressure water outlet 22, thereby increasing the water outlet area.

[0092] It should be particularly noted that the cross-section of the water outlet end 2 is similar to a rectangular structure, and the length direction of the water outlet end 2 is defined as the first direction, which is the extension direction of the water outlet end 2 and is marked by D1. The width direction of the water outlet end 2 is the second direction and is marked by D2. The thickness direction of the water outlet end 2 is the third direction and is the water outlet direction of the water outlet end 2 and is marked by D3. The first direction, the second direction and the third direction are perpendicular to each other, and the first direction, the second direction and the third direction only represent spatial directions and have no practical meaning.

[0093] In one embodiment, Figure 1-Figure 8 As shown, the length of the second pressure water outlet 22 along the first direction is greater than the width of the second pressure water outlet 22 along the second direction.

[0094] That is, the second pressure water outlet 22 is similar to a long strip structure. Under different spraying water pressures, the second pressure water outlet 22 will adaptively deform according to the water pressure, and the expansion degree or opening degree of the second pressure water outlet 22 will change accordingly, so that the water outlet area of ​​the second pressure water outlet 22 changes with the change of water pressure, which can change the water output or water spraying intensity of the second pressure water outlet 22.

[0095] In one embodiment, Figure 1-Figure 10 As shown, a plurality of second pressure water outlets 22 are disposed on at least one side of the first pressure through hole 21 along the first direction.

[0096] Exemplarily, two second pressure outlets 22 are arranged on both sides of the first pressure through hole 21 along the first direction. When the water pressure of the spray water is relatively large, the expansion or expansion direction of the second pressure outlet 22 is also along the first direction, so that the opening of the second pressure outlet 22 can have a larger adjustment range. For example, after the spray water passes through the first pressure through hole 21 and enters the second pressure outlet 22, and the second pressure outlet 22 expands along the first direction, the first pressure through hole 21 and the second pressure outlet 22 can form an elliptical structure, and the major axis of the elliptical structure is arranged parallel to the first direction.

[0097] In one embodiment, side walls of the second pressure water outlet 22 located at least on one side of the first pressure through hole 21 along the first direction and arranged opposite to each other along the second direction are in contact with each other.

[0098] That is, the width of the second pressure water outlet 22 along the second direction is approximately zero. In actual production, a thin slit or a cutting slit can be opened at the corresponding position of the water outlet end 2 to form the second pressure water outlet 22. The structure is simple and the production cost is relatively low. At the same time, when the initial state or the spraying water pressure is relatively small, the side walls of the second pressure water outlet 22 that are arranged opposite to each other along the second direction contact each other, and the second pressure water outlet 22 is in a completely closed state.

[0099] In one embodiment, Figure 1-Figure 11 As shown, the side wall of the second pressure water outlet 22 located at least on one side of the first pressure through hole 21 along the first direction and arranged opposite to each other along the second direction is at least one of a straight line, a wavy line, and a broken line.

[0100] For example, Figure 1-Figure 10 As shown, when the side walls of the second pressure water outlet 22 relatively arranged along the second direction are straight lines, the second pressure water outlet 22 is similar to a straight-line structure, with a simple processing technology and relatively low production cost, and the side wall edges of the straight structure are relatively smooth, reducing the risk of residual impurities such as scale and facilitating the discharge of impurities such as scale.

[0101] In this way, when the spray water pressure is low, only the first pressure through hole 21 with a circular structure discharges water, and the water discharge area is small; when the spray water pressure is high, two second pressure outlets 22 with a slit structure are arranged on both sides of the first pressure through hole 21, so that the circular first pressure through hole 21 gradually changes to an ellipse under high pressure and the water discharge area increases, and the spray force of the water outlet end 2 does not increase significantly with the increase in pressure. By setting the first pressure through hole 21 with a circular structure and setting two second pressure outlets 22 on both sides of the first pressure through hole 21, the water outlet end 2 is easy to deform and increase under high pressure, can automatically sense the water pressure, and automatically adjust the shape and water discharge area of ​​the water outlet end 2 accordingly, and is conducive to the discharge of granular impurities.

[0102] For example, Fig.11As shown, when the side walls of the second pressure water outlet 22 oppositely arranged along the second direction are wavy lines or fold lines, the two side walls of the second pressure water outlet 22 oppositely arranged along the second direction are mutually nested structures, ensuring the reliability of closing the second pressure water outlet 22 when the spray water pressure is relatively small. Specifically, the protrusion of one side wall of the first pressure through hole 21 along the second direction is inserted into the groove of the other side wall. When the spray water is sprayed 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.

[0103] In one embodiment, Figure 1-Figure 8 As shown, along the first direction, the ratio of the length of the second pressure water outlet 22 to the length of the water outlet end 2 is greater than 1 / 3.

[0104] If the length of the second pressure outlet 22 along the first direction is relatively small, the second pressure outlet 22 can be suddenly opened when the water pressure of the spray water must reach a very high pressure, and the water outlet force of the spray water changes significantly with the water pressure. By setting the ratio of the length of the second pressure outlet 22 to the length of the water outlet end 2 to be greater than 1 / 3, the length of the second pressure outlet 22 is relatively long, and it is easy to open when the water pressure of the spray water is relatively low. The opening time of the second pressure outlet 22 is relatively early and the continuity of the start-up is good. The opening degree of the second pressure outlet 22 changes with the change of the water pressure of the spray water. The opening degree of the second pressure outlet 22 is gradual, so that the water outlet force of the spray water does not increase significantly with the increase of the water pressure, and the uniformity of the impact of the spray water is improved.

[0105] In one embodiment, Fig.12 As shown, one end of the second pressure water outlet 22 close to the first pressure through hole 21 is arranged flush with the edge of the water outlet end 2 .

[0106] In this way, one end of the second pressure water outlet 22 extends to the first pressure through hole 21, and the other end extends to the edge of the water outlet end 2, so that the length range of the second pressure water outlet 22 is expanded to the maximum, so that the first pressure through hole 21 and the second pressure water outlet 22 are throughout the entire length range of the water outlet end 2 along the first direction. When the spraying water pressure is relatively low, the second pressure water outlet 22 is easy to be opened, and when the spraying water pressure is relatively high, the water outlet area of ​​the second pressure water outlet 22 is relatively large, reducing the impact force of the spraying water, thereby reducing the difference between high and low pressure spraying water.

[0107] In one embodiment, Fig.13 As shown, a notch 13 is provided on the peripheral side of the water outlet body 1 , and the notch 13 is correspondingly provided with the second pressure water outlet 22 and is connected with the second pressure water outlet 22 .

[0108] In this way, the length of the second pressure water outlet 22 is further extended along the edge of the water outlet 2, which is equivalent to further increasing the overall length of the second pressure water outlet 2, making it easier to deform when the spray water pressure is high, which is conducive to adaptive deformation with the change of the spray water pressure, thereby promoting the adaptation of the water outlet 2. At the same time, it is easy to discharge impurities such as scale.

[0109] In one embodiment, Fig.14 As shown, along the first direction and in a direction away from the first pressure through hole 21 , the width of the second pressure water outlet 22 along the second direction gradually decreases.

[0110] That is, the width of the second pressure water outlet 22 along the second direction is not completely the same, but a variable width structure. The farther the distance between the second pressure water outlet 22 and the first pressure through hole 21 is, the smaller the width along the second direction corresponding to this position is. As the spray water pressure gradually increases, the second pressure water outlet 22 gradually opens, and the opening of the second pressure water outlet 22 also gradually increases, and the water outlet area of ​​the second pressure water outlet 22 also becomes larger. That is, when the area of ​​the water outlet end remains unchanged, a larger spray water pressure corresponds to a larger water outlet area, further improving the uniformity of the water outlet of the spray water.

[0111] In one embodiment, Fig.15 As shown, a plurality of second pressure water outlets 22 are disposed on both sides of the first pressure through hole 21 along the second direction.

[0112] Exemplarily, two second pressure outlets 22 are arranged on both sides of the first pressure through hole 21 along the second direction. When the water pressure of the spray water is relatively large, the expansion or expansion direction of the second pressure outlet 22 is also along the second direction. Since the width of the water outlet end 2 along the second direction is relatively small, the opening of the second pressure outlet 22 can be limited within a certain range to avoid the risk of easy tearing or difficulty in resetting after a large deformation of the water outlet end 2. For example, after the spray water passes through the first pressure through hole 21 and enters the second pressure outlet 22, and 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, and the major axis of the elliptical structure is arranged parallel to the second direction.

[0113] In one embodiment, Fig.16 As shown, the plurality of second pressure water outlets 22 are distributed along the circumferential direction of the first pressure through hole 21 .

[0114] For example, the four second pressure water outlets 22 are evenly distributed along the circumferential direction of the first pressure through hole 21, and the angle between two adjacent second pressure water outlets 22 is 90°. At this time, the four second pressure water outlets 22 form a cross-shaped structure. In this way, when the water pressure of the spray water is relatively large, the water outlet area of ​​the water outlet end 2 can be further increased to achieve the purpose of reducing the high-pressure impact force.

[0115] Of course, in some embodiments, the plurality of second pressure water outlets 22 may be unevenly distributed along the circumferential direction of the first pressure through hole 21, or only part of the second pressure water outlets 22 may extend along the first direction or the second direction. In this case, the plurality of second pressure water outlets 22 are radially arranged around the first pressure through hole 21, and the opening of the second pressure water outlets 22 may also be automatically adjusted according to the water pressure of the spray water.

[0116] In one embodiment, Figure 15-16 As shown, the side walls of the second pressure water outlet 22 located at at least one side of the first pressure through hole 21 along the second direction and arranged opposite to each other along the first direction are in contact with each other.

[0117] That is, the width of the second pressure water outlet 22 along the first direction is approximately zero. In actual production, a thin slit or a cutting slit can be opened on at least one side of the water outlet end 2 along the second direction to form the second pressure water outlet 22. The structure is simple and the production cost is relatively low. At the same time, when the initial state or the spraying water pressure is relatively small, the side walls of the second pressure water outlet 22 that are oppositely arranged along the first direction contact each other, and the second pressure water outlet 22 is in a completely closed state.

[0118] In one embodiment, the side wall of the second pressure water outlet 22 located at least on one side of the first pressure through hole 21 along the second direction and arranged opposite to each other along the first direction is at least one of a straight line, a wavy line, and a broken line.

[0119] Exemplarily, when the side wall of the second pressure water outlet 22 relatively arranged along the first direction is a straight line, the second pressure water outlet 22 is similar to a straight-line structure, with a simple processing technology and relatively low production cost, and the side wall edge of the straight structure is relatively smooth, reducing the risk of residual impurities such as scale and facilitating the discharge of impurities such as scale.

[0120] Exemplarily, when the side walls of the second pressure water outlet 22 oppositely arranged along the first direction are wavy lines or fold lines, the two side walls of the second pressure water outlet 22 oppositely arranged along the first direction are mutually nested structures, ensuring the reliability of closing the second pressure water outlet 22 when the spray water pressure is relatively small. Specifically, the protrusion of one side wall of the first pressure through hole 21 along the first direction is inserted into the groove of the other side wall. When the spray water is sprayed 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.

[0121] In one embodiment, along the second direction and in a direction away from the first pressure through hole 21 , the width of the second pressure water outlet 22 along the first direction gradually decreases.

[0122] That is, the width of the second pressure water outlet 22 along the first direction is not exactly the same, but a variable width structure. The farther the distance between the second pressure water outlet 22 and the first pressure through hole 21 is, the smaller the width along the first direction corresponding to this position is. As the spray water pressure gradually increases, the second pressure water outlet 22 gradually opens, and the opening of the second pressure water outlet 22 also gradually increases, and the water outlet area of ​​the second pressure water outlet 22 also becomes larger. That is, when the area of ​​the water outlet surface remains unchanged, a larger spray water pressure corresponds to a larger water outlet area, further improving the uniformity of the water outlet of the spray water.

[0123] This embodiment also provides a shower head, such as Figure 17-Figure 21 As shown, the shower head includes a shower body 200 , a water distribution component 300 , a cover 400 and the above-mentioned water outlet structure 100 . The water distribution component 300 is disposed between the shower body 200 and the cover 400 , and the water outlet structure 100 passes through the cover 400 .

[0124] In the shower head provided in this embodiment, the shower head body 200 plays the role of accommodation and support, the water distribution assembly 300 plays the role of water distribution, is used to increase multiple spray modes, and provides an installation position for the water outlet structure 100. The cover 400 plays a covering role to improve the aesthetics, and the water outlet end 2 of the water outlet structure 100 can be extended from the cover 400 for easy cleaning.

[0125] The water outlet structure 100 further includes a mounting portion 3 (such as Figure 1 and Figure 5 As shown in the figure, the mounting portion 3 is arranged at one end of the water outlet body 1 away from the water outlet end 2, that is, the mounting portion 3 is arranged around the top of the water outlet body 1, and the mounting portion 3 can be connected to the water distribution component 300 by a detachable connection method such as bolt connection and clamping, or can be fixed to the water distribution component 300 by welding. The mounting portion 3 and the water outlet body 1 can be an integrated structure, which reduces the time of parts assembly and reduces the production cost.

[0126] In one embodiment, Figure 21-24As shown, the shower head further includes a fixed seat 700 and a control intermittent structure 800. The fixed seat 700 is arranged in the shower head body 200, and the fixed seat 700 provides an installation or rotation 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 swing rod 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 seat 700 through the first pin 802, and the other end abuts against the swing rod 8040. The swing rod 8040 is rotatably connected to the fixed seat 700 through the second pin 803. A first return spring 805 is arranged between the slider 806 and the fixed seat 700. One end of the slider 806 abuts against an end of the swing rod 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 disposed inside the pawl 808 and sleeved outside the rotating block 807. A second spring 810 is disposed between the rotating block 807 and the fixed seat 700.

[0127] When the button 801 is pressed, the button 801 rotates around the first pin 802, driving the rocker arm 8040 to rotate around the second pin 803, and the rocker arm 8040 drives the slider 806 to move toward the direction close to the pawl 808 and compresses 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 pin 804. The pawl 808 drives the ratchet 809 to rotate counterclockwise through a ratchet angle. When the button 801 is released, the first return spring 805 resets and drives the pawl 808, the rocker arm 8040, and the button 801 to their initial positions. The ratchet 809 is fixed at the switched position under the action of the stop claw 8091, thereby realizing a function switch.

[0128] Specifically, Fig.21 As shown, the water distribution component 300 is arranged between the fixing seat 700 and the cover 400, and the water distribution component 300 includes a water distribution plate 301, a water distribution body 302 and a water distribution seat 303, and a sealing gasket 304 is arranged 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, and the water distribution plate 301 can rotate synchronously with the ratchet 809. Four water inlet holes are arranged on the water distribution plate 301, and six water outlet holes 305 (such as Fig.25 As shown), the three functions of intermittent water discharge are realized in this way. How to realize the intermittent water discharge is not the main utility model point of the present invention, so it is not described in detail.

[0129] In one embodiment, the shower head further includes a sealing ring 900 and a bubbler 1000. The bubbler 1000 is disposed between the water diversion seat 303 and the face cover 400 to generate bubbles and improve the user's shower experience. The sealing ring 900 is disposed between the bubbler 1000 and the water diversion body 302 to ensure the sealing effect of the bubbler 1000.

[0130] After the shower is turned off, the first pressure through hole 21 of the water outlet 2 will return to a small round hole. When the shower is hung on the socket, due to the large inclination angle of the shower, the residual water takes a very long time to be discharged from the first pressure through hole 21. If you go out for a long time, bacteria will grow in the shower.

[0131] To solve this problem, Figure 25-Figure 31 As shown, the shower head further includes a core shaft 500 and a discharge valve 600. The core shaft 500 is arranged in the shower head body 200. A siphon chamber 501 is arranged in the core shaft 500. The water distribution component 300 is provided with a water discharge hole 305. The water discharge hole 305 is connected with the water outlet structure 100 and the siphon chamber 501. The discharge valve 600 is arranged at one end of the siphon chamber 501 away from the water outlet structure 100, and is used to discharge the residual water in the siphon chamber 501.

[0132] Since the drain hole 305 is connected to the siphon chamber 501, 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 pressed into the siphon chamber 501 through the drain hole 305 to generate a siphon effect, so that the residual water in the drain hole 305 is sucked into the siphon chamber 501, and then the residual water is quickly discharged through the discharge valve 600. The discharge valve 600 can discharge all the spray water in 5 seconds at the fastest, so the discharge valve 600 can also be called a quick discharge valve. The shower head provided by the present disclosure is provided with a discharge valve 600 in the shower head body 200, so that the residual water in the shower head body 200 can be drained in a short time, preventing the residual water from dripping onto the wiped body, and at the same time reducing the situation where bacteria are easily grown due to long time outdoors.

[0133] In one embodiment, Figure 25-Figure 31 As shown, the discharge valve 600 includes a valve seat 601, a valve core 602, an elastic member 603 and a valve body 604. The valve seat 601 is installed at one end of the siphon cavity 501 away from the water outlet structure 100, that is, located 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 member 603 are arranged in the valve cavity. The elastic member 603 is arranged between the valve core 602 and the valve body 604. The elastic member 603 can be a spring. The valve core 602 is used to selectively block the quick-discharge hole 6011.

[0134] When the water is flowing, the spray water passes through the water inlet of the valve body 604 or the gap between the valve body 604 and the siphon chamber 501, and the valve core 602 overcomes the elastic force of the elastic member 603 to block the quick discharge hole 6011, and water can flow normally. When the water is turned off, the valve core 602 is reset to the initial position under the elastic force of the elastic member 603, and the quick discharge hole 6011 is opened. The residual water at the water outlet end 2 will be quickly discharged to the outside of the shower along the quick discharge hole 6011 under the action of siphon, so that the water outlet structure 100 of the shower will not drip residual water for a long time, and the dripping and leakage of the water outlet structure 100 is reduced.

[0135] In one embodiment, a check valve 1100 is further disposed at the bottom end of the discharge valve 600 to prevent the backflow of the spray water.
