[0016] From the above description of the various embodiments of the present invention, it can be seen that, compared with the prior art, the various embodiments of the present invention have the following advantages:

[0017] Beneficial effects:

[0018] In the first technical solution and related embodiments, the valve realizes the rotation and pressing operation of the valve stem by designing a press-and-pop mechanism, thereby controlling the opening and closing of the water passage by the blocking member, thus becoming a new type of valve structure. When the valve stem rotates and stops at the first position along the pressing direction, the blocking member closes the water passage and prevents the passage of water; and when the valve stem rotates and stops at the second position, the blocking member opens the water passage and allows water to pass. By at least partially installing the valve stem into the blocking member along the axial direction, the space of the accommodating cavity inside the blocking member is cleverly utilized, and the axial extension of the entire valve mechanism is effectively shortened, thereby achieving a compact overall structure. Unlike the prior art in which the press-and-pop mechanism is usually stacked on the outside, making the product appear bulky as a whole, this valve reduces the external space required for the product and can adapt to a variety of space-restricted environments.

[0019] In the second technical solution and related embodiments, the accommodating hole is provided in the accommodating groove, so as to shorten the axial space of the pressing and bouncing mechanism and the blocking member.

[0020] In the third technical solution and related embodiments, sealing members are provided at both ends of the blocking member, and the inlet and outlet water paths can be flexibly provided by providing the blocking or opening conditions of the two sealing members or one of the two sealing members and the valve body, thereby satisfying more design scenarios. At the same time, since the sealing cross-sectional areas of the two ends of the blocking member provided with the two sealing members are the same or similar, the force is evenly applied, making pressing less laborious.

[0021] In the fourth technical solution and related embodiments, the guide groove is connected to the guide hole, and the accommodating groove and the accommodating hole are connected. When the push-and-pop mechanism is pressed, the water flow can form a circulation inside the plugging member through the guide groove and the guide hole, effectively balancing the water pressure difference between the upper and lower ends of the plugging member, so that the force required for pressing is lighter and the hand feel is better.

[0022] In the fifth technical solution and related embodiments, the plug-in fit between the rib and the limit groove realizes a non-rotation fit between the blocking member and the valve, so that the blocking member can be pressed and slid relative to the valve body between the first position and the second position while preventing its axial rotation.

[0023] In the sixth technical solution and related embodiments, the push-bounce mechanism is a ballpoint pen-type push-bounce mechanism, and the rotation of the valve stem is achieved by the cooperation of the oblique teeth of the pressure rod and the abutting inclined surfaces of the flange of the valve stem.

[0024] In the seventh technical solution and related embodiments, the first rib of the pressure rod is slidably matched with the guide groove and is stopped by the limit column, ensuring that the pressure rod always slides in the pressing direction during the pressing process to prevent its axial rotation. The limit column, the guide groove and the flange cooperate to enable the valve stem to slide between the first position and the second position along the pressing direction and stop.

[0025] In the eighth technical solution and related embodiments, a balancing rod is installed between the button and the valve body, so that the large-area edge of the button can be pressed evenly and the valve can be switched by pressing anywhere on the edge of the button.

[0026] In the ninth technical solution and related embodiments, which is one of the embodiments, the water passage enters from the side of the blocking member and exits from the bottom end of the blocking member along the pressing direction.

[0027] In the tenth technical solution and related embodiments, which is one of the embodiments, the water passage enters from the side of the blocking member and exits from the top end of the blocking member along the pressing direction.

[0028] In the eleventh technical solution and related embodiments, the water outlet device using the above-mentioned valve is suitable for a variety of application scenarios, such as a water outlet device with a relatively thin handle, or requiring multiple switches, or switching water on and off in multiple water outlet modes.

[0052] See also Figures 1 to 12 ,like Figure 1 and Figure 2 As shown, a valve includes a valve body, a press-and-pop mechanism 3 , a blocking member 4 , a first elastic member 5 and a button 6 .

[0053] The valve body includes a valve seat 2 and a valve cover 1. The valve body is provided with a water passage and a valve cavity 11. The outer wall of the valve cavity 11 is provided with a convex rib 12 extending in the pressing direction, and the inner wall of the valve cavity 11 is circumferentially provided with a plurality of limit posts 13 extending in the pressing direction, and a guide groove 16 is formed between two adjacent limit posts 13.

[0054] The valve seat 2 is an integrally welded assembly, and the water passage is arranged inside the valve seat 2. One end of the valve seat 2 is a handle connected to the first water inlet end 28, and the other end is connected to the water outlet end.

[0055] Valve cover 1, such as Figures 1 to 4 As shown, the valve chamber 11 is arranged on the valve cover 1. Figure 3 As shown, the number of ribs 12 is several. Figure 1 and Figure 2 As shown, the valve cover 1 is detachably and water-tightly connected to the valve seat 2. Specifically, the valve cover 1 is sealed and connected to the valve seat 2 via an O-ring 18 and fixed via screws 19. Figure 4 As shown, the valve cover 1 is provided with a plurality of guide holes 17 extending in the pressing direction along the circumferential direction, and the valve cover 1 is also provided with a plurality of pivots 21 .

[0056] like Figure 1 As shown, the valve cover 1 is provided with a second water inlet end 29 connected with the first water inlet end 28, and the second water inlet end 29 is located on the side of the valve cover 1 facing the first water inlet end 28 of the valve seat 2, and a special-shaped ring 25 is used to water-seal between the first water inlet end 28 and the second water inlet end 29.

[0057] Press the bounce mechanism 3, such as Figure 1 , Figure 2 and Figure 7 As shown, it includes a pressing rod 31, a second elastic member 32 and a valve stem 33. The valve stem 33 rotates relative to the valve body and stops at a first position or a second position along the pressing direction. The pressing and bouncing mechanism 3 is accommodated in the valve cavity 11 of the valve cover 1 and is sealed and connected with the Y-ring 26 using a pressing cover 27.

[0058] The pressure rod 31, such as Figure 2 As shown, it is provided with a mounting groove 39 opening along the pressing direction. Figure 7 As shown, a plurality of first ribs 34 distributed circumferentially are provided on one side of the pressure rod 31 facing the valve stem 33 . The first ribs 34 extend along the pressing direction and form oblique teeth 35 at one end close to the valve stem 33 .

[0059] The valve stem 33 is provided with a plurality of flanges 36 distributed circumferentially, each flange 36 is provided with two abutting inclined surfaces 37 facing each other and extending along the axial direction and forming a tooth groove 38, and the oblique teeth 35 of two adjacent first ribs 34 respectively cooperate with the two abutting inclined surfaces 37 to drive the valve stem 33 to rotate. In this embodiment, the push-and-pop mechanism 3 is a ballpoint pen-type push-and-pop mechanism 3, and the rotation of the valve stem 33 is achieved by the cooperation of the oblique teeth 35 of the pressure rod 31 and the abutting inclined surfaces 37 of the flange 36 of the valve stem 33.

[0060] Specifically, Figure 3 and Figure 7 As shown, the first rib 34 of the pressure rod 31 is suitable for sliding with the guide groove 16 along the pressing direction and is stopped by the limit column 13; the flange 36 of the valve stem 33 is adapted to the guide groove 16 and slides along the guide groove 16 when the pressure rod 31 is driven, until the flange 36 leaves the guide groove 16 and is separated from the stop limit of the limit column 13, the valve stem 33 rotates axially, and the limit column 13 presses against the tooth groove 38 of the flange 36 to stop the valve stem 33 at the second position; when the pressure rod 31 is pressed again, the flange 36 is separated from the guide groove 16 again, the valve stem 33 continues to rotate axially, the flange 36 slides into the adjacent guide groove 16, and the valve stem 33 returns to the first position. In this embodiment, the first rib 34 of the pressure rod 31 is slidably matched with the guide groove 16 and is stopped by the limit column 13, which ensures that the pressure rod 31 always slides along the pressing direction during the pressing process to prevent its axial rotation. The cooperation among the limiting column 13, the guide groove 16 and the flange 36 enables the valve stem 33 to slide along the pressing direction between the first position and the second position and stop.

[0061] The second elastic member 32, such as Figure 2 As shown, it is installed between the pressure rod 31 and the valve stem 33. Specifically, the second elastic member 32 is a spring. The second elastic member 32 is sleeved on the upper end of the valve stem 33 along the pressing direction and installed in the mounting groove 39. After the pressure rod 31 is pressed, the elastic force of the second elastic member 32 is used to return the pressure rod 31 to the initial position.

[0062] Blocking member 4, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, it is open at both the top and the bottom and is cylindrical. The blocking member 4 abuts against the valve stem 33 away from the pressing direction and stops rotating relative to the valve body. When the valve stem 33 is parked at the first position, the blocking member 4 closes the water passage. When the valve stem 33 is parked at the second position, the blocking member 4 opens the water passage. The blocking member 4 and the valve stem 33 at least partially overlap along the axial direction.

[0063] Specifically, Figure 5 and Figure 6 As shown, the blocking member 4 is provided with a receiving groove 41 which is open in a direction away from the pressing direction, and a receiving hole 42 which passes through the receiving groove 41 from top to bottom is provided therein, and the valve stem 33 is at least partially sleeved in the receiving hole 42 along the axial direction.

[0064] In this embodiment, by at least partially inserting the valve stem 33 into the plugging member 4 in the axial direction, the space of the accommodation cavity inside the plugging member 4 is cleverly utilized, and the extension of the entire valve mechanism in the axial direction is effectively shortened, thereby achieving a compact overall structure. Unlike the prior art in which the push-and-pop mechanism 3 is usually stacked on the outside, which makes the product as a whole bulky, this valve reduces the external space required for the product and can adapt to a variety of space-constrained environments. By providing an accommodation hole 42 in the accommodation groove 41, the axial space between the push-and-pop mechanism 3 and the plugging member 4 is shortened.

[0065] like Figure 6 As shown, the bottom of the receiving groove 41 is also provided with a guide hole 43, and the hole wall of the receiving hole 42 is circumferentially provided with a guide groove 44 that penetrates the receiving groove 41. The guide groove 44 is connected with the guide hole 43 to balance the water pressure when the push-and-pop mechanism 3 is pressed. The receiving groove 41 and the receiving hole 42 are connected through the guide groove 44 and the guide hole 43. When the push-and-pop mechanism 3 is pressed, the water flow can form a circulation inside the blocking member 4 through the guide groove 44 and the guide hole 43, effectively balancing the water pressure difference between the upper and lower ends of the blocking member 4, so that the force required for pressing is lighter and the hand feel is better.

[0066] like Figure 5 and Figure 6As shown, the bottom of the accommodating groove 41 is also provided with a limiting groove 46 that cooperates with the valve body, and the number of the limiting grooves 46 is consistent with the convex rib 12. The convex rib 12 and the limiting groove 46 are plugged and matched to prevent the blocking member 4 from rotating with the valve body. The plugging and matching of the convex rib 12 and the limiting groove 46 realizes the anti-rotation cooperation between the blocking member 4 and the valve, so that the blocking member 4 can be pressed and slid relative to the valve body between the first position and the second position while preventing its axial rotation.

[0067] Seal 45, such as Figure 1 and Figure 2 As shown, sealing members 45 are sleeved at both ends of the blocking member 4 along the pressing direction, and the sealing cross-sectional areas of the two ends of the blocking member 4 where the two sealing members 45 are sleeved are the same or similar. Specifically, the sealing member 45 is an O-ring, and the two sealing rings are the same size. Sealing members 45 are sleeved at both ends of the blocking member 4, and the inlet and outlet waterways can be flexibly set by setting the two sealing members 45 or one of them to block or open the valve body to meet more design scenarios. At the same time, since the sealing cross-sectional areas of the two ends of the blocking member 4 are the same or similar, the force is evenly applied, making pressing less laborious.

[0068] The first elastic member 5, such as Figure 1 and Figure 2 As shown, it is located between the blocking member 4 and the valve body so that the blocking member 4 abuts against the valve stem 33 away from the pressing direction. Specifically, the first elastic member 5 is a spring. After the pressing of the pressure rod 31 is released, when the valve stem 33 stops at the second position, the first elastic member 5 uses its elastic force to make the blocking member 4 abut against the valve stem 33 away from the pressing direction. At the same time, after the pressure rod 31 is pressed again and removed, the valve stem 33 rotates and slides into the adjacent guide groove 16, and the first elastic member 5 uses its elastic force to make the blocking member 4 abut against the valve stem 33 away from the pressing direction.

[0069] Button 6, such as Figure 1 , Figure 2 and Figure 8 As shown, it is connected to the pressing and bouncing mechanism 3 for preventing rotation. Specifically, the button 6 is connected to the pressure rod 31 for preventing rotation. The button 6 is provided with a groove 63 opening along the pressing direction. The inner wall of the groove 63 is provided with a plurality of protrusions 64 along the circumferential direction for preventing rotation with the pressure rod 31.

[0070] The button 6 is detachably connected to the valve body and is suitable for being pressed along a pressing direction. Figure 3 As shown, the valve cover 1 is provided with a plurality of hooks 22 which are downwardly pressed in the circumferential direction. Figure 8 As shown, the button 6 is provided with an elastic claw 65 which is upward in the pressing direction and adapted to the hook 22. The button 6 is provided with a plurality of guide posts 62 in the circumferential direction of the pressing direction. Figure 4 As shown, the valve cover 1 is provided with a plurality of guide holes 17 opening along the pressing direction, and the guide posts 62 are adapted to the guide holes 17 so that the button 6 can be easily pressed along the pressing direction.

[0071] A balance rod 20 is installed between the edge of the button 6 and the valve body to balance the force on the button 6. Figure 1 As shown, the balance bar 20 is a U-shaped bar, which is installed at the edge of the key 6 in the vertical pressing direction and is located at the position where the hand presses. Figure 8 As shown, the button 6 is provided with a plurality of columns, each of which is provided with a hook groove 61, and the opening of the hook groove 61 is along the vertical pressing direction to support the balance rod 20. Figure 4 As shown, the valve cover 1 is provided with a plurality of pivots 21 away from the pressing direction to support the movement of the limit balance rod 20. The balance rod 20 is arranged between the button 6 and the valve body, so that the large area edge of the button 6 can be pressed evenly, and the valve can be switched by pressing any edge of the button 6.

[0072] In this embodiment, the valve realizes the rotation and pressing operation of the valve stem 33 by designing the pressing and bouncing mechanism 3, thereby controlling the opening and closing of the water passage by the blocking member 4, and becomes a new valve structure. When the valve stem 33 rotates and stops at the first position along the pressing direction, the blocking member 4 closes the water passage and prevents the water from passing through; and when the valve stem 33 rotates and stops at the second position, the blocking member 4 opens the water passage and allows the water to pass through.

[0073] The water inlet and outlet passages of the valve can be flexibly arranged to meet the requirements of more design scenarios. The following two embodiments arrange the water passage according to the abutment between one of the seals 45 and the valve body.

[0074] Embodiment 1

[0075] like Fig. 9 As shown, when the valve stem 33 is in the second position, a first water passage 23 is formed between the sealing member 45 below the blocking member 4 along the pressing direction and the valve body away from the water inlet end, and the water passage is opened. Fig.10 As shown, when the valve stem 33 is in the first position, the water passage is closed. In this embodiment, the water passage enters from the side of the blocking member 4 and exits from the bottom end of the blocking member 4 along the pressing direction.

[0076] Embodiment 2

[0077] like Fig.11 As shown, when the valve stem 33 is in the second position, a second water passage 24 is formed between the sealing member 45 above the pressing direction of the blocking member 4 and the valve body near the water inlet end, and the water passage is opened. Fig.12 As shown, when the valve stem 33 is in the first position, the water passage is closed. In this embodiment, the water passage enters from the side of the blocking member 4 and exits from the top end of the blocking member 4 along the pressing direction.
