Detailed implementation manners

[0042] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0043] The present utility model relates to an instant-stop water outlet structure, including a water distribution assembly 100, a water outlet assembly 200, a valve plate 400, an elastic member 500, and a piston section.

[0044] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the water distribution assembly 100 is provided with an incoming water flow channel 110 for connecting to an external water supply system. The incoming water flow channel 110 can have a water inlet 141 opened on the surface of the water distribution assembly 100. The water outlet assembly 200 is connected to the water distribution assembly 100, and the connection between the water outlet assembly 200 and the water distribution assembly 100 can be achieved through methods such as screw connection, snap connection, screw connection, or pressing. An outlet cavity 300 is defined between the water outlet assembly 200 and the water distribution assembly 100. The water outlet assembly 200 is provided with a plurality of water outlets 210. A first water passing port 120 is provided between the incoming water flow channel 110 and the outlet cavity 300. The incoming water flow channel 110, the first water passing port 120, the outlet cavity 300, and the water outlets 210 are connected in sequence. The valve plate 400 is installed in the outlet cavity 300 and can move between a first position and a second position in the outlet cavity 300. When the valve plate 400 moves to the first position, the valve plate 400 blocks each water outlet 210, and at this time, no water can pass through each water outlet 210. When the valve plate 400 moves to the second position, the valve plate 400 opens each water outlet 210, that is, at this time, each water outlet 210 can pass water. The elastic member 500 can be installed in the outlet cavity 300. One end of the elastic member 500 abuts against the water distribution assembly 100 or the water outlet assembly 200, or abuts against other components installed in the outlet cavity 300. In this embodiment, one end of the elastic member 500 abuts against the water outlet assembly 200, and the other end abuts against the valve plate 400. The elastic member 500 can be a component such as a spring that can undergo elastic deformation. The elastic member 500 exerts an elastic force on the valve plate 400. The elastic force drives the valve plate 400 to move towards the first position, that is, the valve plate 400 remains at the first position under the elastic force of the elastic member 500 alone to block each water outlet 210. The piston member 600 is disposed between the incoming water flow channel 110 and the outlet cavity 300. It can be that the piston member 600 passes through the water distribution assembly 100, and the piston member 600 can move on the water distribution assembly 100. The piston member 600 has a first pressure receiving surface 601 and a second pressure receiving surface 602. The first pressure receiving surface 601 and the second pressure receiving surface 602 can be respectively located on both end faces of the piston member 600. The first pressure receiving surface 601 faces the incoming water flow channel 110, and the first pressure receiving surface 601 is in communication with the incoming water. The second pressure receiving surface 602 faces the outlet cavity 300, and the second pressure receiving surface 602 is in communication with the outlet cavity 300. The area of the first pressure receiving surface 601 is larger than the area of the second pressure receiving surface 602.

[0045] In actual use, the instant stop water outlet structure can be applied to a water outlet device. The water outlet device can be a shower head, a spray gun, a shower head, etc. In this embodiment, as Figure 14 shown, the water outlet device is a shower head, and the instant stop water outlet structure is installed inside the shower head. One end of the incoming water flow channel 110 is connected to the water inlet channel of the shower head. When not in use, as Figure 5 and Figure 6, the valve plate 400 is in the first position under the elastic force of the elastic member 500, and each water outlet 210 is in a blocked state to cut off water. When using water, such as Figure 7 and Figure 8 , external water enters the water inlet channel 110 through the shower head. The water flows along the water inlet channel 110 and enters the water outlet cavity 300 through the first water passing opening 120. At this time, the first pressure receiving surface 601 is subjected to the water pressure in the water inlet channel 110, and the second pressure receiving surface 602 is subjected to the water pressure in the water outlet cavity 300. According to the pressure formula F = p * s, where F is the pressure, p is the pressure intensity, and s is the area, the water pressure received by the first pressure receiving surface 601 is F1 = p1 * s1, and the water pressure received by the second pressure receiving surface 602 is F2 = p2 * s2. The pressure intensities in the water inlet channel 110 and the water outlet cavity 300 are the same, that is, p1 = p2. Since the area of the first pressure receiving surface 601 is larger than the area of the second pressure receiving surface 602, that is, s1 > s2, then F1 > F2, and at the same time, the difference between F1 - F2 is greater than the elastic force. After water is passed, the piston member 600 moves toward the water outlet cavity 300 under the action of the pressure difference between the first pressure receiving surface 601 and the second pressure receiving surface 602. The piston member 600 abuts against the valve plate 400 and pushes the valve plate 400 to move to the second position, thereby opening each water outlet 210. The water in the water outlet cavity 300 will spray out from each water outlet 210 for use. When the water use stops, the external water stops supplying water to the water inlet channel 110. At this time, the water pressures in the water inlet channel 110 and the water outlet cavity 300 disappear. The piston member 600 and the valve plate 400 are reset to the first position under the elastic action of the elastic member 500, so that each water outlet 210 is immediately blocked to cut off water after the water is cut off, restricting the water in the water outlet cavity 300 from slowly and intermittently continuing to drip to the outside from the water outlet 210, thereby realizing the instant stop function. With the assistance of the instant stop function of the instant stop water structure, the water outlet device can instantaneously stop water outlet, effectively avoiding water dripping during non-water use periods, generating noise or dripping on the user, which affects the user experience.

[0046] In some embodiments of the present invention, such as Figure 4 、 Figure 5 、 Figure 7 and Figure 10As shown in the figure, an active cavity 130 is provided on the water distribution component 100. One, two or more active cavities 130 can be provided. In this embodiment, four active cavities 130 are provided on the water distribution component 100, and the active cavities 130 can be evenly distributed around the center of the water distribution component 100 at equal intervals. The active cavity 130 is connected between the water inlet flow channel 110 and the water outlet cavity 300. The interior of the active cavity 130 is medium. One end opening of the active cavity 130 is connected to the water inlet flow channel 110, and the other end opening is connected to the water outlet cavity 300. The piston member 600 is movably installed in the active cavity 130, and a sealed sliding connection is provided between the piston member 600 and the interior of the active cavity 130. It can be that the outer wall or the whole of the piston member 600 is made of rubber or other materials, and the outer wall of the piston member 600 fits on the inner wall of the active cavity 130 to prevent the water in the water inlet flow channel 110 from directly flowing into the water outlet cavity 300 through the active cavity 130. It can also be that a sealing ring is sleeved on the piston member 600, and the sealing ring abuts against the inner wall of the active cavity 130 to seal the water.

[0047] The piston member 600 can be set to a conical shape, a stepped shape or other structures to form a first pressure receiving surface 601 and a second pressure receiving surface 602 with different areas. The shape of the active cavity 130 is adapted to the shape of the piston member 600. In this embodiment, as Figure 4 , Figure 5 and Figure 7 shown, the active cavity 130 includes a first cavity 131 and a second cavity 132. The first cavity 131 and the second cavity 132 are distributed in a stepped hole shape. The inner diameter of the first cavity 131 is larger than the inner diameter of the second cavity 132. The first cavity 131 and the second cavity 132 are interconnected. The first cavity 131 is connected to the water inlet flow channel 110, and the second cavity 132 is connected to the water outlet cavity 300. The piston member 600 is in the shape of a stepped shaft and includes a first shaft section 610 and a second shaft section 620. The outer diameter of the first shaft section 610 is larger than the outer diameter of the second shaft section 620. The piston member 600 is installed in the active cavity 130, and the first shaft section 610 slides in the first cavity 131, and the second shaft section 620 slides in the second cavity 132. Correspondingly, sealing rings can be sleeved on the first shaft section 610 and the second shaft section 620 respectively to make sealed sliding connections with the first cavity 131 and the second cavity 132 respectively. The end face of the first shaft section 610 facing the water inlet flow channel 110 forms the first pressure receiving surface 601, and the end face of the second shaft section 620 facing the water outlet cavity 300 forms the second pressure receiving surface 602. Among them, in order to ensure that there is water pressure acting on the second pressure receiving surface 602, a protrusion can be provided on the second pressure receiving surface 602, or an avoidance hole can be provided on the valve plate 400, etc., to ensure that after the piston member 600 abuts against the valve plate 400, the water entering the water outlet cavity 300 can act on the second pressure receiving surface 602.

[0048] Furthermore, the axial length of the first shaft segment 610 is less than the axial height of the first cavity 131. After the piston member 600 is installed in the movable cavity 130, an air cavity 133 is defined between the first shaft segment 610 and the first cavity 131. The air cavity 133 will change dynamically as the first shaft segment 610 moves. When the piston member 600 moves towards the water outlet cavity 300, the volume of the air cavity 133 decreases. When the piston member 600 moves towards the water inlet channel 110, the volume of the air cavity 133 increases. A vent hole 134 is formed in the side wall of the first cavity 131, and the vent hole 134 connects the air cavity 133 to the atmosphere. When the piston member 600 moves and the volume of the air cavity 133 changes, the vent hole 134 is used to keep the air cavity 133 at atmospheric pressure.

[0049] In some specific embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 9 , Figure 10 and Figure 11As shown, the water distribution assembly 100 includes a water distribution tray 140 and a water distribution body 150. The water distribution tray 140 and the water distribution body 150 can be set in a disc shape or the like. An inlet 141 and a first partition 142 are provided on the water distribution tray 140. The first partition 142 extends from one side surface of the water distribution tray 140. A second partition 151, a third partition 152 and a plurality of movable cavities 130 are provided on the water distribution body 150. The plurality of movable cavities 130 can be evenly distributed around the center of the water distribution body 150 at equal intervals. The second partition 151 can extend from the side surface of the water distribution body 150 and be located between the outer walls of adjacent movable cavities 130. The third partition 152 can extend from the side surface of the water distribution body 150 and be located between the outer walls of adjacent movable cavities 130. A second flow channel 112 is defined between the second partition 151 and the third partition 152. The water distribution tray 140 covers the water distribution body 150, and a first flow channel 111 is defined between the first partition 142 and the second partition 151. The inlet 141 is communicated with the first flow channel 111. A second water passing port 135 and a third water passing port 136 are formed on the side wall of the movable cavity 130. The second water passing port 135 is communicated with the first flow channel 111, and the third water passing port 136 is communicated with the second flow channel 112. A first water passing port 120 is formed on the water distribution body 150. The first water passing port 120 can be multiple, and the first water passing port 120 is communicated with the second flow channel 112. It can be that the first water passing port 120 is located between the second partition 151 and the third partition 152. The first flow channel 111, the movable cavity 130, the cavity communicated with the first flow channel 111 and the second flow channel 112, and the second flow channel 112 are sequentially communicated to form an inlet water flow channel 110. The outside water sequentially flows through the inlet 141, the first flow channel 111, the second water passing port 135, the movable cavity 130, the third water passing port 136, the second flow channel 112, and the first water passing port 120 and flows to the outlet cavity 300. After the water in the first flow channel 111 enters the movable cavity 130, it will be blocked by the piston member 600, and the water cannot directly flow through the movable cavity 130 to the outlet cavity 300. The water can only flow from the third water passing port 136 to the second flow channel 112. Before the water flows to the second flow channel 112, it must flow through the movable cavity 130, thereby generating a pressure on the first pressure receiving surface 601 of the piston member 600, ensuring that the piston member 600 will surely push the valve plate 400 to move to the second position after water is passed.

[0050] The sealing structure of the valve plate 400 for the water outlet 210 can be to provide a sealing gasket or the like at the position of the valve plate 400 corresponding to each water outlet 210, and use the sealing gasket to block the water outlet 210. In some specific embodiments of the present invention, such as Figure 6 , Figure 7 , Figure 12 and Figure 13As shown, a plurality of valve posts 410 are provided on the valve plate 400. The valve posts 410 are paired and inserted into the water outlet 210 one by one. The valve posts 410 move with the valve plate 400 between the first position and the second position. The water outlet 210 is blocked or opened by the valve posts 410.

[0051] Specifically, the valve plate 400 is arranged in a circular plate shape. The valve plate 400 has a first surface 401 and a second surface 402 in the thickness direction. The first surface 401 faces the water distribution assembly 100, and the second surface 402 faces the water outlet 210. The valve post 410 includes a water passage section 411 and a plunger head 412. The water passage section 411 extends from the second surface 402. A plurality of water passage grooves 413 are provided on the circumferential side wall of the water passage section 411. The water passage grooves 413 extend axially along the water passage section 411 to the first surface 401, and one end of the water passage groove 413 is opened on the first surface 401. The plunger head 412 is located at the end of the water passage section 411 away from the second surface 402. The plunger head 412 and the water passage section 411 can be integrally formed. The outer diameter of the plunger head 412 is larger than the outer diameter of the water passage section 411, and the two are distributed in a stepped manner. The water outlet 210 has a first end 211 and a second end 212. The plunger head 412 passes through the first end 211 and extends into the water inlet 141. The first end 211 is in a constricted shape, and the outer diameter of the plunger head 412 is larger than the inner diameter of the first end 211. When the valve plate 400 moves, the plunger head 412 remains in the water outlet 210. In the direction shown in the figure, when the plunger head 412 moves upward toward the first end 211, the valve plate 400 moves to the first position, and the plunger head 412 blocks the first end 211. When the plunger head 412 moves downward toward the second end 212, the valve plate 400 moves to the second position. At this time, the plunger head 412 leaves the first end 211, the first end 211 is opened, and there is a certain gap between the plunger head 412 and the inner wall of the water inlet 141. The water passage groove 413 extends into the water inlet 141. Water enters the water passage cavity 213, then flows into the water passage groove 413 from the end of the water passage groove 413 on the first surface 401. The water enters the water outlet 210 along the water passage groove 413, and then the water is ejected from the second end 212 for use.

[0052] Further, as Figure 6 and Figure 7As shown, the water outlet 210 includes a water passage chamber 213 and a reduced-diameter chamber 214. The inner diameter of the water passage chamber 213 is larger than that of the reduced-diameter chamber 214. The first end 211 is the end of the water passage chamber 213 far from the reduced-diameter chamber 214. The second end 212 is the end of the reduced-diameter chamber 214 far from the water passage chamber 213. Among them, the plunger head 412 can be set to a conical shape. The inner diameter at the position of the first end 211 of the water passage chamber 213 is the smallest, and then the water passage chamber 213 gradually expands in the direction of the reduced-diameter chamber 214. When the plunger head 412 moves upward to the first position, the upper part of the plunger head 412 abuts against the inner wall of the first end 211 to achieve sealing. When the plunger head 412 moves downward to the second position, the plunger head 412 leaves the first end 211, and there is a certain gap between the outer wall of the plunger head 412 and the inside of the water passage chamber 213. The water trough 413 extends into the water passage chamber 213 through the first end 211.
