Description

Technical Field

[0001] This utility model relates to the field of water discharge products, specifically to a water discharge device. Background Technology

[0002] To facilitate descaling and drainage of the water outlet, the water outlet is usually designed to be sliding. When the water is turned on, the water outlet moves to disengage from the descaling needle, and when the water is turned off, it resets to re-engage with the descaling needle to achieve descaling. However, the driving force of the spring is insufficient, resulting in slow reset, slow drainage, and a long dripping time in the water outlet. Utility Model Content

[0044] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0045] refer to Figures 1-10 A water outlet device includes a housing 1, a water outlet component 2, a magnetic module 9, a water inlet connector 3, a first biasing component 4, a support plate 25, a gasket 6, a sealing component 7, and a collar 8.

[0046] The housing 1 is used to install other parts. The housing 1 includes an end cap 11, a pressure cap 12, a lower body 13, and a face cover 14.

[0047] refer to Figure 2 The cover 14 has several through holes for the water outlet portion of the water outlet component 2 to extend out and discharge water. (Reference) Figure 8The face cover 14 is fixedly connected to the end cover 11, such as by welding, bonding, screw connection, snap-fit, etc. After the face cover 14 and the end cover 11 are fixedly connected, they form a water passage 15. The water passage 15 includes a sealing hole 151 and a water passage cavity 152. Water passes through the sealing hole 151 and the water passage cavity 152 in sequence. The sealing hole 151 is the water inlet end of the water passage 15. The water passage 15 has a sealing surface 153 at the water passage cavity 152. The sealing surface 153 is formed by the end cover 11 and its orientation is the first direction 51. The descaling needle 111 is installed on the housing 1. In this embodiment, the descaling needle 111 is not movable relative to the housing 1, while the water outlet 2 is movable relative to the housing 1. The descaling needle 111 is fixedly connected to the end cover 11 of the housing 1 and is integrally formed. Specifically, the end cover 11 is also provided with a plurality of descaling needles 111 protruding from the sealing surface 153 along the first direction 51. In other embodiments, however, the descaling needle 111 is movable relative to the housing 1, while the water outlet 2 is not movable relative to the housing 1. The end cap 11 is provided with a threaded portion 112 adapted to engage with the pressure cap 12. The movable parts in the descaling needle 111 and the water outlet 2 relative to the housing 1 are adapted to be driven by water pressure.

[0048] refer to Figure 2 The lower body 13 is fitted over the end cap 11 and fixed to the face cap 14, such as by welding, bonding, screw connection, snap-fit, etc. After the lower body 13 is fitted over the end cap 11, the threaded portion 112 is exposed on the lower body 13. The pressure cap 12 is threadedly engaged with the threaded portion 112 and abuts against the lower body 13 along the first direction 51.

[0049] The water inlet connector 3 is connected to the water inlet ball of the water passage 15. Specifically, it has a washer 6, a seal 7, and a collar 8, all of which are fitted onto the water inlet connector 3. The collar 8 is located on one side of the ball of the water inlet connector 3, and the seal 7 and the washer 6 are located on the other side of the ball of the water inlet connector 3. The seal 7 is used to prevent water leakage, and the collar 8 and the washer 6 prevent the ball of the water inlet connector 3 from detaching. The washer 6 is located on the end cap 11, and the collar 8 has a stepped surface 81. Through the threaded engagement of the pressure cap 12 with the end cap 11, the pressure cap 12 presses the stepped surface 81 of the collar 8 in the direction close to the washer 6, so that the collar 8 and the washer 6 are respectively clamped on both sides of the ball of the water inlet connector 3, thereby locking the water inlet connector 3; at the same time, the pressure cap 12 abuts against the lower body 13, so that the lower body 13 abuts against the face cap 14 and the pressure cap 12 in the first direction 51 and the second direction 52, respectively. After the water inlet connector 3 is connected to the water inlet end ball of the water passage 15, the housing 1 can rotate relative to the multiple free ends of the water inlet connector 3, thereby adjusting the water outlet angle of the water outlet hole 211 on the water outlet component 2.

[0050] The water outlet 2 is installed in the housing 1. The water outlet 2 is adapted to be inserted into the end cap 11 along the second direction 52. Then, the face cover 14 is fixed to the end cap 11 to form a water passage 15, and the face cover 14 is adapted to support the water outlet 2. (Reference) Figure 4 , Figure 5The water outlet component 2 includes a fixing part 23, a deformation part 22, and a water outlet part 21.

[0051] The water outlet 21 is provided with a water outlet hole 211 suitable for communicating with the water passage 15, and the water outlet hole 211 is provided in a one-to-one correspondence with the descaling needle 111. The water outlet 21 includes a sealing part 212, which is suitable for sealing with the sealing hole 151 to isolate the water passage between the water passage cavity 152 and the sealing hole 151. The sealing part 212 can be formed by a Y-shaped sealing ring. When water flows through the water passage 15, that is, when water enters through the sealing hole 151 and reaches a certain pressure, the sealing part 212 is driven by the water pressure, causing the water outlet part 21 to slide along the first direction 51, and causing the sealing part 212 to disengage from the sealing hole 151. At this time, the water passage cavity 152 is suitable for connecting the sealing hole 151 and the water outlet 211, and the descaling needle 111 is disengaged from the water outlet 211. The descaling needle 111 is no longer located in the water outlet 211, or the portion located in the water outlet 211 is reduced, to ensure normal flow out of the water outlet 211. Furthermore, the water outlet end of the water outlet 211 extends out of the housing 1. In this embodiment, when the water outlet part 21 abuts against the cover 14, it is located at the limit position of sliding along the first direction 51.

[0052] The water outlet 21 is also provided with a first surface 213, which faces the sealing surface 153 of the end cover 11. The water inlet end of the water outlet hole 211 is located on the first surface 213. The water outlet 21 is provided with a sealing rib 214 protruding from the first surface 213, which surrounds the water inlet end of the water outlet hole 211.

[0053] refer to Figures 8-9 When the water outlet 21 slides along the second direction 52, which is opposite to the first direction 51, the descaling needle 111 extends into the water outlet 211 to remove scale. When the sealing rib 214 abuts against the sealing surface 153, the water inlet end of the water outlet 211 is sealed and isolated from the water inlet end and the water passage 15, and is located at the limit position of sliding along the second direction 52. At this time, the water outlet end of the water outlet 211 is hidden inside the housing 1. When the sealing part 212 disengages from the sealing hole 151, the sealing rib 214 disengages from the sealing surface 153.

[0054] refer to Figure 10 The fixing part 23 abuts against the housing 1 along the first direction 51 and the second direction 52, and seals with the housing 1. Specifically, the upper and lower ends of the fixing part 23 abut against the end cover 11 and the face cover 14 respectively, and are squeezed by the sealing protrusion on the end cover 11 to achieve sealing, and realize the installation of the water outlet part 2.

[0055] The deformable part 22 connects the fixed part 23 and the water outlet part 21. The deformable part 22 is adapted to deform so that the water outlet part 21 slides along the first direction 51, and to recover when the water outlet part 21 slides along the second direction 52, so as to facilitate the next deformation. In this embodiment, the deformable part 22 is wavy.

[0056] To achieve a better seal, the water outlet component 2 is made of a flexible material, but to improve its strength, reference is made to... Figure 5 The water outlet component 2 includes a water outlet nozzle 26 and a support plate 25. The water outlet nozzle 26 has a deformable part 22, a fixed part 23, a water outlet hole 211, a first surface 213, and a sealing rib 214. The water outlet nozzle 26 is made of a flexible material to facilitate cleaning the water outlet hole 211 and achieving sealing. The water outlet component 2 also includes a support plate 25, which is made of a rigid material (usually without deformable function). It is fixed to the water outlet nozzle 26 and together forms the water outlet part 21, and provides strength. The support plate 25 is suitable for installing a Y-shaped sealing ring and a first magnetic element 24 that form the sealing part 212. Since the first surface 213 needs to be sealed, the support plate 25 is not fixed to it, and it is better to use a flexible water outlet nozzle 26.

[0057] In this embodiment, the structure of the water outlet 2 is relatively complex. In other embodiments, the water outlet 2 may be just a panel with a water outlet hole 211, and allow it to slide in a sealed manner relative to the housing 1 so that the descaling needle 111 can extend into or out of the water outlet hole 211.

[0058] The first magnetic component 24 is installed on a part that can move relative to the housing 1 in either the water outlet component 2 or the descaling needle 111. In this embodiment, it is installed on the water outlet component 2.

[0059] refer to Figure 8 The water outlet component 2 is provided with a first magnetic component 24, which is located in the middle of the water outlet component 2 and installed on the water outlet section 21.

[0060] One end of the first biasing member 4 acts on the water outlet 2 or the descaling needle 111, and the other end acts on the housing 1. It is adapted to store energy when the descaling needle 111 disengages from the water outlet 211. In this embodiment, energy is stored when the water outlet 21 slides along the first direction 51, so as to release energy when the water is stopped in the water passage 15, so that the descaling needle 111 extends into the water outlet 211, and the water outlet 21 slides along the second direction 52. Specifically, the two ends of the first biasing member 4 act on the cover 14 and the water outlet 21, respectively. In this embodiment, the first biasing member 4 is a spring.

[0061] refer to Figures 6-10 The magnetic module 9 is installed in the housing 1. The magnetic module 9 includes a housing 911, a first cover 912, a second cover 913, a coil 93, a second biasing element 94, a button 922, a tactile switch 923, a control board 921, a second magnetic element 95, a sensor 96, and a battery 97.

[0062] Sensor 96 is adapted to emit a water-stop signal when it senses water stopping in the water passage 15. Control board 921 is adapted to, upon receiving the water-stop signal, cause the second magnetic element 95 to interact with the first magnetic element 24, so that the descaling needle 111 extends into the water outlet 211. Sensor 96 is also adapted to emit a water-flow signal when it senses water flowing through the water passage 15. Control board 921 is adapted to, upon receiving the water-flow signal, cause the second magnetic element 95 and the first magnetic element 24 to act in opposite directions, so that the descaling needle 111 disengages from the water outlet 211.

[0063] It should be understood that when the first magnetic element 24 is installed on the descaling needle 111, the control plate 921 is adapted to make the second magnetic element 95 attract the first magnetic element 24 when receiving a water stop signal, and to make the second magnetic element 95 repel the first magnetic element 24 when receiving a water flow signal; while when the first magnetic element 24 is installed on the water outlet 2, the control plate 921 is adapted to make the second magnetic element 95 repel the first magnetic element 24 when receiving a water stop signal, and to make the second magnetic element 95 attract the first magnetic element 24 when receiving a water flow signal, the opposite of the above.

[0064] refer to Figure 7 The outer casing 911 is fixed to the housing 1, and the outer wall of the outer casing 911 is threadedly connected to the cover 14. A first cover 912 is placed on the opening of the outer casing 911 near the water outlet 2 and can be fixed by glue or other means. A second cover 913 is placed on the opening of the outer casing 911 away from the water outlet 2. The second cover 913 has a pressing hole for a button 922 to extend from it. The button 922 is adapted to slide to trigger a tactile switch 923 located inside the outer casing 911. The tactile switch 923 is electrically connected to the control board 921 and is located inside the outer casing 911, allowing manual control of the magnetism of the second magnetic component 95, such as by single and double clicks, or short and long presses to form two control signals. A battery 97 is used to power the control board 921, the tactile switch 923, and the sensor 96, and is installed inside the outer casing 911. Sensor 96 extends into the water passage cavity 152, and its wire extends into the interior of housing 911 through an opening in the side wall of housing 911 to be electrically connected to control board 921. Sensor 96 is adapted to emit a water stop signal when it senses water stopping in water passage 15, and to emit a water passage signal when it senses water flowing in water passage 15. Sensor 96 can be a flow sensor or a water pressure sensor. The second magnetic element 95 is an iron core. The second biasing element 94 causes the second magnetic element 95 to abut against the first cover 912. The two ends of the second biasing element 94 act on the second magnetic element 95 and housing 911 respectively. In this embodiment, the second biasing element 94 is a spring.

[0065] refer to Figure 8 , Figure 9A coil 93 is wound around the outside of the second magnetic element 95. A control board 921 is located inside the housing 911 and is adapted to send a drive signal to drive the coil 93 when a water flow signal is received. When the coil 93 is energized, the second magnetic element 95 becomes magnetic, attracting the second magnetic element 95 to the first magnetic element 24, causing the water outlet 21 to slide along the first direction 51. When a water stop signal is received, the control board 921 drives the coil 93. At this time, the drive signal sent by the control board 921 to the coil 93 is opposite to the above, causing the magnetism of the second magnetic element 95 to be opposite, making the second magnetic element 95 repel the first magnetic element 24, causing the water outlet 21 to slide along a second direction 52 opposite to the first direction 51, allowing the descaling needle 111 to extend into the water outlet hole 211. The control board 921 is adapted to stop the second magnetic element 95 from working after a certain period of mutual repulsion between the second magnetic element 95 and the first magnetic element 24, preventing the repulsive force from affecting the sliding of the water outlet 21 when hot water is flowing. Preferably, the magnitude of the repulsive and attractive forces can be adjusted by the magnitude of the current output by the control board 921.

[0066] Initially, reference Figure 9 , Figure 10 Under the action of the first biasing element 4, the water outlet 21 is in the water-stopping position. At this time, the sealing part 212 seals the sealing hole 151, the sealing rib 214 seals against the sealing surface 153, and the descaling needle 111 is located inside the water outlet 211. (Reference) Figure 8 When water enters the inlet connector 3, water enters the sealing hole 151, and the water pressure acts on the sealing part 212, causing the deformation part 22 to begin to deform. The water outlet part 21 slides along the first direction 51, and the first biasing element 4 stores energy. When water enters the water passage chamber 152, the control board 921 receives the water passage signal from the sensor 96, causing the second magnetic element 95 to attract the first magnetic element 24, so that the water outlet part 21 slides along the first direction 51, reducing the water pressure. During this process, the water outlet hole 211 gradually disengages from the descaling needle 111, and the sealing rib 214 disengages from the sealing surface 153, so that the water outlet hole 211 communicates with the water passage chamber 152, and water begins to flow out. The water outlet end of the water outlet hole 211 extends out of the housing 1. It is stopped when the water outlet part 21 abuts against the housing 1 or the magnetic module 9. At this time, the water outlet part 21 is in the water outlet position, and the water flow is optimal.

[0067] refer to Figure 8 , Figure 9When the water is turned off, the water outlet 21 first slides along the second direction 52 under the action of the first biasing member 4, the deformation part 22 returns to its original state, and the sealing part 212 gradually seals the sealing hole 151. Due to the movement of the water outlet 21, the water passage cavity 152 becomes smaller, which is equivalent to a smaller water storage space, allowing the water in the water passage cavity 152 to be quickly discharged, reducing the residual water dripping time; until the sealing rib 214 seals against the sealing surface 153, sealing each water outlet 211 independently, preventing the remaining water from flowing out, and further reducing the dripping time. The descaling needle 111 also returns to its original position in the water outlet 211, achieving descaling. At the same time, after the water in the water passage 152 is drained, the control board 921 receives the water stop signal from the sensor 96, causing the second magnetic element 95 to repel the first magnetic element 24, causing the water outlet 21 to slide along the second direction 52, so that the sealing part 212 and the sealing hole 151 are resealed; after the water is stopped for a certain period of time, the control board 921 controls the second magnetic element 95 to lose its magnetism, ensuring that the water outlet 21 can slide easily when the water is turned on next time.

[0072] The water outlet 2 is installed on the housing 1 and has a water outlet hole 211 adapted to communicate with the water passage 15 so as to realize water outlet when connected;

[0073] The first magnetic element 24 is installed on either the water outlet element 2 or the descaling needle 111, and is adapted to be driven by water pressure so that the descaling needle 111 is disengaged from the water outlet 211. Under the action of water force, the water outlet 211 is automatically opened or the water outlet area of ​​the water outlet 211 is increased, thereby increasing the water output.

[0074] The magnetic module 9 includes a control board 921, a second magnetic component 95, and a sensor 96. The sensor 96 is adapted to send a water-stop signal when it senses that the water passage 15 has stopped. When the control board 921 receives the water-stop signal, it is adapted to make the second magnetic component 95 interact with the first magnetic component 24 so that the descaling needle 111 extends into the water outlet 211 to achieve the descaling effect. The descaling action is controlled by magnetic force, which is more stable and has a stronger driving force compared to the biasing method.

[0075] In one exemplary embodiment, the sensor 96 is adapted to send a water flow signal when it senses water flowing through the water passage 15, and the control board 921 is adapted to cause the second magnetic element 95 and the first magnetic element 24 to act in opposite directions when receiving the water flow signal, so as to disengage the descaling needle 111 from the water outlet 211, thereby assisting the descaling needle 111 from the water outlet 211 together with the water force, reducing the starting force when the water pressure is started.

[0076] In one exemplary embodiment, a water outlet device includes a housing 1, a water outlet component 2, and a magnetic module 9. The housing 1 is provided with a water passage 15 and a descaling needle 111;

[0077] The water outlet 2 is installed on the housing 1 and includes a water outlet 21. The water outlet 21 is provided with a water outlet hole 211 suitable for communicating with the water passage 15. The water outlet 21 is suitable for sliding along the first direction 51 driven by water pressure when water passes through the water passage 15, so that the descaling needle 111 is disengaged from the water outlet hole 211, so that the descaling needle 111 does not affect the water flow and is more convenient due to hydraulic drive.

[0078] The magnetic module 9 is installed on the housing 1 for installation. The water outlet 2 is provided with a first magnetic element 24; the magnetic module 9 includes a control board 921, a second magnetic element 95 and a sensor 96. The sensor 96 is adapted to emit a water stop signal when it senses that the water passage 15 is stopped. When the control board 921 receives the water stop signal, it is adapted to make the second magnetic element 95 and the first magnetic element 24 repel each other, so that the water outlet 21 slides in a second direction 52 opposite to the first direction 51, so that the descaling needle 111 extends into the water outlet hole 211 to achieve descaling. This action is automatically triggered when the water is turned off, which is convenient and quick. During this action, due to the large enough repulsive force, the water outlet 21 moves towards the descaling needle 111, which makes the internal space of the water passage 15 smaller, which facilitates the rapid discharge of water and reduces the dripping time of the water outlet hole 211.

[0079] In one exemplary embodiment, the sensor 96 is adapted to send a water flow signal when it senses water flowing through the water passage 15, and the control board 921 is adapted to attract the second magnetic element 95 and the first magnetic element 24 when it receives the water flow signal, so that the water outlet 21 slides along the first direction 51, thereby assisting the water pressure to slide the water outlet 21, making the water outlet process of the water outlet 21 faster and reducing the starting force when the water pressure is started.

[0080] In one exemplary embodiment, the water passage 15 includes a sealing hole 151 and a water passage cavity 152. The water passage cavity 152 is adapted to connect the sealing hole 151 and the water outlet 211. The water outlet 21 also includes a sealing part 212, which is adapted to seal and cooperate with the sealing hole 151, so that energy can be stored even under low pressure, making the water outlet 21 easier to slide. When the water outlet 21 slides along the first direction 51, the sealing part 212 disengages from the sealing hole 151, thereby achieving sequential communication between the sealing hole 151, the water passage cavity 152, and the water outlet 211, and realizing water discharge. When water is stopped, under the action of repulsion, the sealing part 212 and the sealing hole 151 reseal the water outlet 21, preventing water from being discharged from the sealing hole 151 and reducing the dripping time. Since the water passage cavity 152 and the water outlet 211 are connected at least initially when water is stopped, water in the water passage cavity 152 can be discharged from the water outlet 211 when water is stopped. The sensor 96 extends into the water passage cavity 152 and can sense the water stop. The control board 921 is adapted to stop the second magnetic element 95 from working after the second magnetic element 95 and the first magnetic element 24 have repelled each other for a certain period of time, to prevent the repulsion from affecting the sliding of the water outlet 21 when the water is turned on, which would prevent water from entering the water passage cavity 152 and prevent the sensor 96 from sending a water discharge signal.

[0081] In one exemplary embodiment, one end of the first biasing member 4 acts on the water outlet member 2 or the descaling needle 111, and the other end acts on the housing 1. It is adapted to store energy when the descaling needle 111 is separated from the water outlet 211, so as to release energy when the water is stopped through the water channel 15, so that the descaling needle 111 extends into the water outlet 211. Thus, in the initial stage of water stoppage, before the water is discharged (the sensor 96 may not have sensed the water stoppage), the descaling needle 111 is first moved in the direction of extending into the water outlet 211 to assist in water stoppage and achieve descaling.

[0082] In one exemplary embodiment, the water outlet 21 is adapted to extend the water outlet end of the water outlet hole 211 out of the housing 1 when sliding along the first direction 51, so as to prevent water splashes from colliding with the housing 1 and causing a deterioration in the water pattern. When the water outlet 21 slides along the second direction 52, the water outlet end of the water outlet hole 211 is hidden inside the housing 1, which is more aesthetically pleasing and protects the water outlet end of the water outlet hole 211.

[0083] In one exemplary embodiment, the water outlet component 2 further includes a fixing part 23 and a deformable part 22. The deformable part 22 connects the fixing part 23 and the water outlet component 21. The fixing part 23 abuts against the housing 1 along a first direction 51 and a second direction 52 to prevent movement in the first direction 51 and the second direction 52, thereby achieving the installation and fixation of the water outlet component 2. The fixing part 23 and the housing 1 are sealed together to prevent water leakage. The deformable part 22 is adapted to deform so that the water outlet component 21 slides along the first direction 51 and returns to its original position when the water outlet component 21 slides along the second direction 52, assisting the water outlet component 21 in resetting. The deformability of the deformable part 22 allows the water outlet component 21 to slide.

[0084] In one exemplary embodiment, the deformable part 22 is wavy, thereby facilitating deformation.

[0085] In one exemplary embodiment, the water passage 15 is further provided with a sealing surface 153. The water outlet 21 is adapted to abut against the sealing surface 153 when sliding along the second direction 52, so that the water inlet end of the water outlet 211 is sealed and isolated from the water passage 15, thereby preventing residual water in the subsequent water passage cavity 152 from being discharged from the water outlet 211, preventing leakage, and further realizing immediate shutdown.

[0086] In one exemplary embodiment, the water outlet 21 is provided with a first surface 213, the water inlet end of the water outlet hole 211 is located on the first surface 213, the water outlet 21 is provided with a sealing rib 214 protruding from the first surface 213, the sealing rib 214 is arranged around the water inlet end of the water outlet hole 211 and is adapted to seal against the sealing surface 153, and the sealing effect is achieved by the sealing rib 214, which is simple and convenient.

[0087] In one exemplary embodiment, a water inlet connector 3 is also included, which is connected to the water inlet end ball of the water passage 15 to adapt to changing the water outlet direction of the water outlet 211.

[0088] In one exemplary embodiment, the magnetic module 9 further includes a housing 911 and a coil 93. The housing 911 is fixed to the housing 1. The coil 93 is wound around the outside of the second magnetic element 95. The control board 921 is located inside the housing 911 and is adapted to send a drive signal to drive the coil 93 to work when a water flow signal is received. After the coil 93 is energized, the second magnetic element 95 becomes magnetic and attracts the second magnetic element 95 to the first magnetic element 24. The control board 921 is adapted to drive the coil 93 to work when a water stop signal is received. The drive signal sent by the control board 921 to the coil 93 is opposite to the above, so that the magnetism of the second magnetic element 95 is opposite to the above, so that the second magnetic element 95 and the first magnetic element 24 repel each other, so that the descaling needle 111 extends into the water outlet 211. By changing the direction of the current in the coil 93, the magnetism of the second magnetic element 95 is changed, which is relatively simple and convenient.

[0089] In one exemplary embodiment, the magnetic module 9 further includes a button 922 and a tactile switch 923. The button 922 is adapted to slide to trigger the tactile switch 923 located inside the housing 911. The tactile switch 923 is electrically connected to the control board 921 and is located inside the housing 911 so that the magnetism of the second magnetic element 95 can be manually controlled, so that it can still be used when the sensor 96 is damaged or malfunctions, without causing damage to the device. The method of triggering the tactile switch 923 by the button 922 is relatively simple and easy to use.
