Description

Technical Field

[0001] The present invention relates to the technical field of drinking water equipment, and particularly relates to a water outlet device. Background Art

[0002] With the popularization of heated water purifiers, the non-pressure solenoid valves used in current water purifiers on the market often have the phenomenon of water leakage, that is, water still drips from the water outlet or even flows out in a stream after the solenoid valve is closed. Especially when using hot water, it is very easy to scald users, with poor safety. Moreover, the water in the water outlet does not flow out all at once, and when the machine shakes, the remaining water will also flow out from the water outlet, causing water dripping, and the user's water receiving experience is poor. Summary of the Invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a water outlet device, which can make the water flow out of the water outlet in time, so as to avoid the phenomenon of water leakage, and further avoid scalding users when the water flow is hot water, improving the safety in use and the user's water receiving experience. The technical solution is as follows:

[0004] A water outlet device provided by the present invention includes a first pipeline, a second pipeline, a branch pipeline, a solenoid valve assembly and a sealing assembly;

[0005] The water inlet end of the first pipeline is communicated with the water inlet pipe, and the water outlet end of the first pipeline is communicably connected to the second pipeline through the solenoid valve assembly;

[0006] The branch pipeline is provided through the side wall of the second pipeline and obliquely extends from the side wall of the second pipeline. The end of the branch pipeline far from the second pipeline is higher than the end of the branch pipeline connected to the second pipeline;

[0007] The sealing assembly is arranged at the end of the branch pipeline far from the second pipeline. When there is water pressure in the second pipeline, the sealing assembly can seal the branch pipeline under the action of water pressure and move to communicate the branch pipeline with the outside when there is no water pressure in the second pipeline.

[0008] Further, the sealing assembly includes a first sealing member and a sealing cover. After the sealing cover is connected to the branch pipeline, a receiving cavity is formed, and the first sealing member is movably arranged in the receiving cavity;

[0009] A through hole is opened on the sealing cover. When there is water pressure in the second pipeline, the first sealing member can move to be sealingly connected to the through hole under the action of water pressure. When there is no water pressure in the second pipeline, the first sealing member can move to communicate the branch pipeline with the through hole under the action of gravity.

[0010] Further, the first seal includes a moving part and an elastic sealing part. The elastic sealing part is fixedly connected to one end of the moving part away from the second pipeline. When there is water pressure in the second pipeline, the elastic sealing part can abut against the inner wall of the sealing cover under the action of the water pressure to seal the through hole. When there is no water pressure in the second pipeline, the elastic sealing part can be separated from the inner wall of the sealing cover to connect the branch pipe and the through hole.

[0011] Further, the branch pipe is provided with a limiting part. When there is no water pressure in the second pipeline, the first seal can abut against the limiting part under the action of gravity.

[0012] Further, at least one end of the first seal is provided with a guiding part, and the guiding part can extend into the limiting part or the through hole.

[0013] Further, the solenoid valve assembly includes a magnetic part and a second seal sleeved on the magnetic part. The magnetic part and the second seal can move synchronously to make the second seal seal or separate from the water inlet of the second pipeline.

[0014] Further, one end of the magnetic part is provided with a clamping part, and the second seal is provided with a clamping groove. The diameter of the notch of the clamping groove is smaller than the diameter of the bottom of the clamping groove, and the clamping part is embedded in the clamping groove.

[0015] Further, the solenoid valve assembly further includes a first fixing part and an elastic part. The first fixing part is provided with an installation groove, and at least part of the magnetic part is arranged in the installation groove;

[0016] One end of the elastic part is fixed in the installation groove, and the other end of the elastic part abuts against one end of the magnetic part away from the second seal.

[0017] Further, the water outlet end of the first pipeline is provided with a sealing groove, and a third seal is arranged in the sealing groove. The first pipeline is hermetically connected to the first fixing part through the third seal.

[0018] Further, at least one flow guiding boss is arranged on the inner wall of the water outlet of the second pipeline. The flow guiding boss protrudes from the inner wall of the second pipeline towards the central axis of the second pipeline, and a water guiding channel is formed between adjacent flow guiding bosses.

[0019] Implementing the present invention has the following beneficial effects:

[0020] 1. In the present invention, a branch pipe is provided obliquely on the second pipeline for discharging water, and a sealing component is connected to the branch pipe, so that the sealing assembly seals the branch pipe under the action of the water pressure existing in the second pipeline, improving the reliability and safety of water discharge. It also enables the sealing assembly to move to communicate the branch pipe with the outside under the state where there is no water pressure in the second pipeline, and the water outlet of the second pipeline communicates with the atmosphere. The water in the second pipeline flows out of the water outlet in time under the action of its own gravity, reducing the residue of water flow in the second pipeline, so as to avoid the phenomenon that the water outlet of the second pipeline cannot seal the water, and also avoid direct scalding or splashing of users by dripping or flowing hot water in a stream, greatly improving the use safety and enhancing the user's water receiving experience.

[0021] 2. In the present invention, through the moving part and the elastic sealing part arranged at one end of the moving part away from the second pipeline, the first sealing member plays a one-way sealing role, that is, the end of the first sealing member close to the second pipeline can always communicate with the second pipeline, avoiding the accidental blockage of the branch pipe. And the end with the elastic sealing member is sealed with the sealing cover under the action of water pressure or separated from the sealing cover in the state of no water pressure, with good flexibility, high overall reliability and good stability during use.

[0022] 3. In the present invention, a diversion boss is arranged at the water outlet of the second pipeline, which further cooperates with the sealing assembly to promote the water flow in the second pipeline to flow out in time, further avoiding the phenomenon that the second pipeline cannot seal the water, and improving the user's use feeling and use safety.

[0033] Embodiment 1

[0034] The embodiment of the present invention provides a water outlet device, such as Figure 1As shown, the water outlet device includes a first pipeline 1, a second pipeline 2, a branch pipe 4, a solenoid valve assembly 3 and a sealing assembly 5. Among them, the water inlet end of the first pipeline 1 is connected to the water inlet pipe, and the water outlet end 11 of the first pipeline 1 is connected to the second pipeline 2 through the solenoid valve assembly 3 in a switchable manner. The branch pipe 4 is arranged through the side wall of the second pipeline 2 and extends obliquely from the side wall of the second pipeline 2. The end of the branch pipe 4 far from the second pipeline 2 is higher than the end of the branch pipe 4 connected to the second pipeline 2, that is, the branch pipe 4 is arranged obliquely upward. The sealing assembly 5 is arranged at the end of the branch pipe 4 far from the second pipeline 2. When the solenoid valve assembly 3 is opened, the first pipeline 1 and the second pipeline 2 are connected, so that water flows out of the second pipeline 2. At the same time, along the direction of water flow out, there is a relatively small water pressure in the second pipeline 2. In the case of the existence of water pressure in the second pipeline 2, the sealing assembly 5 can seal the branch pipe 4 under the action of water pressure, so as to prevent water from flowing out of the branch pipe 4 during the normal water outlet of the water outlet device, which may cause waste or even scald the user. When the solenoid valve assembly 3 is closed, the first pipeline 1 and the second pipeline 2 are disconnected. At this time, there is almost no water pressure in the second pipeline 2. Then, in the state where there is no water pressure in the second pipeline 2, the sealing assembly 5 can move to connect the branch pipe 4 with the outside under the action of its own gravity, so that the inside of the second pipeline 2 is connected to the outside for air intake. At this time, the inside of the second pipeline 2 and its water outlet are at the same atmospheric pressure as the outside. The remaining water flow in the second pipeline 2 can flow out of the water outlet of the second pipeline 2 in time under the action of its own gravity, reducing the remaining amount of water flow in the second pipeline 2, and there will be no water remaining at the water outlet. Furthermore, it can avoid the situation that water drips or flows out in a stream from the water outlet after the user finishes receiving water, solve the problem that the existing water outlet device is prone to water leakage, and greatly improve the user experience.

[0035] Specifically, as Figure 1 shown, the water inlet of the second pipeline 2 is higher than the water outlet of the second pipeline 2, so that the water flow can flow out in time under the action of its own gravity when the solenoid valve assembly 3 is closed. In this embodiment, the second pipeline 2 is arranged vertically, with a simple structure and can effectively prevent water from remaining at the water outlet.

[0036] Specifically, as Figure 2As shown in the figure, the solenoid valve assembly 3 includes a magnetic member 31 and a second seal 32 sleeved on the magnetic member 31. The magnetic member 31 and the second seal 32 can move synchronously, so that the second seal 32 is hermetically connected to or separated from the water inlet of the second pipeline 2. When the solenoid valve assembly 3 is opened, the magnetic member 31 moves in a direction away from the water inlet of the second pipeline 2 under the electromagnetic force, driving the second seal 32 to separate from the water inlet of the second pipeline 2, so as to conduct the first pipeline 1 and the second pipeline 2, and make the water flow out smoothly from the water outlet of the second pipeline 2. When the solenoid valve assembly 3 is closed, when the electromagnetic force disappears, the magnetic member 31 moves in the direction of the water inlet of the second pipeline 2, driving the second seal 32 to be hermetically connected to the water inlet of the second pipeline 2, and the water outlet stops discharging water. It is convenient to switch, has good smoothness when discharging water, and good sealing performance when closing water, improving the user experience.

[0037] In this embodiment, the first pipeline 1 and the second pipeline 2 are low-pressure and small-flow pipelines, and the solenoid valve assembly 3 is a pressureless solenoid valve. When working, no external pressure is required. Only by moving the magnetic member 31 through the electromagnetic force, the solenoid valve assembly 3 can be opened or closed, controlling the connection or disconnection of the first pipeline 1 and the second pipeline 2, and the control is simple, convenient and labor-saving.

[0038] Specifically, as Figure 3 shown, the diameter of the end of the second seal 32 away from the magnetic member 31 is larger than the inner diameter of the water inlet of the second pipeline 2, that is, the end face of the second seal 32 that can abut against the water inlet of the second pipeline 2 can completely cover the entire water inlet with which it abuts, so that the second seal 32 can effectively cut off the water flow, disconnect the first pipeline 1 and the second pipeline 2, and has good sealing performance and reliability in the closed state of the solenoid valve assembly 3.

[0039] Specifically, as Figure 4 shown, one end of the magnetic member 31 is provided with a clamping portion 310, and the second seal 32 is provided with a clamping groove. The diameter of the groove opening of the clamping groove is smaller than the diameter of the groove bottom of the clamping groove, and the clamping portion 310 is embedded in the clamping groove. In some embodiments, the diameter of the end of the clamping portion 310 connected to the magnetic member 31 is smaller than the diameter of the other end of the clamping portion 310, so that a clamping groove recessed in the direction of the central axis of the magnetic member 31 is formed at the connection between the main body structure of the magnetic member 31 and the clamping portion 310. When the second seal 32 is sleeved on the magnetic member 31, the clamping groove can accommodate the clamping portion 310, and the groove opening of the clamping groove can be correspondingly clamped to the clamping groove, forming limits in the up and down directions to prevent the second seal 32 from falling off the magnetic member 31, with good anti-detachment effect and improving the structural stability of the solenoid valve assembly 3. In this embodiment, the cross-section of the clamping portion 310 is an inverted T-shape, which is convenient to process and has a firm clamping.

[0040] In some embodiments, the material of the magnetic member 31 is a magnetic material, which includes at least one of rare earth permanent magnet materials and ferrite permanent magnet materials. It has good magnetism and can move stably under the drive of electromagnetic force. In this embodiment, the magnetic member 31 is an armature, with easily obtainable material, convenient processing, good magnetism, capable of effectively moving under the action of electromagnetic force, easy to drive, and easy to control the movement precision.

[0041] In some embodiments, the second seal 32 is at least one of a frustum shape, a truncated cone shape, a semi-ellipsoidal shape, and a hemispherical shape, and the end face area of the second seal 32 away from the magnetic member 31 is larger than the end face area of the second seal 32 close to the magnetic member 31. When the solenoid valve assembly 3 is closed, it can completely cover the water inlet of the second pipeline 2 to effectively isolate the first pipeline 1 and the second pipeline 2 and stop the water flow. In this embodiment, as Figure 4 shown, the second seal 32 is frustum-shaped, and the bottom of the frustum shape has a certain thickness to further improve the sealing performance between the second seal 32 and the second pipeline 2 when the solenoid valve assembly 3 is closed, with good reliability.

[0042] Optionally, the second seal 32 is an elastic seal, which can enhance the sealing performance between the solenoid valve assembly 3 and the water inlet of the second pipeline 2, improve the reliability when the solenoid valve assembly 3 is closed, and prevent the phenomenon of water leakage. In this embodiment, the elastic seal is made of silicone material, with low processing and forming difficulty, high forming precision, good elasticity, convenient for the installation of the magnetic member 31 and the second seal 32, and can also effectively improve the sealing reliability.

[0043] Specifically, as Figure 2 shown, the solenoid valve assembly 3 further includes a first fixing member 33 and an elastic member 34. Among them, the first fixing member 33 is fixed on the water outlet end 11 of the first pipeline 1. The first fixing member 33 is provided with an installation groove, at least part of the magnetic member 31 is arranged in the installation groove, and the installation groove can play a guiding role as the track for the up and down movement of the magnetic member 31, restricting the movement direction of the magnetic member 31 so that the magnetic member 31 can move linearly along the installation groove under the action of electromagnetic force.

[0044] Specifically, one end of the elastic member 34 is fixed in the installation groove, and the other end of the elastic member 34 abuts against the end of the magnetic member 31 away from the second seal 32. The elastic member 34 is used to buffer the moving speed of the magnetic member 31 when the magnetic member 31 is subjected to electromagnetic force, so that the magnetic member 31 moves smoothly, the water flow from the second pipeline 2 is stable, not easy to scald, and has good safety. The elastic member 34 can also push the magnetic member 31 to reset when the magnetic member 31 is not subjected to electromagnetic force, abutting against the water inlet end of the second pipeline 2, improving the sealing reliability when the solenoid valve assembly 3 is closed, and preventing the situation of water leakage. In this embodiment, the elastic member 34 is a compression spring, with convenient assembly, good elasticity, and easy to control the deformation stroke.

[0045] Specifically, in some alternative embodiments, as Figure 3 shown, one end of the magnetic member 31 connected to the elastic member 34 is provided with an avoidance boss 311. The diameter of the avoidance boss 311 is smaller than the maximum diameter of the magnetic member 31, and the diameter of the avoidance boss 311 is smaller than the inner diameter of the installation groove, so as to reduce the contact area between the top of the magnetic member 31 and the first fixing member 33, prevent excessive contact from affecting the up and down movement of the magnetic member 31, reduce jamming, and improve the smoothness of the movement of the magnetic member 31; in addition, the gap between the avoidance boss 311 and the installation groove can also be used to accommodate one end of the elastic member 34 that abuts against the magnetic member 31, facilitating the abutment of the elastic member 34 and the magnetic member 31, and also preventing the elastic member 34 from being stuck with the side wall of the installation groove of the first fixing member 33 during the movement, which is beneficial to improving the structural reliability and driving smoothness of the solenoid valve assembly 3.

[0046] In this embodiment, the installation groove extends vertically upward from the first fixing member 33, and the magnetic member 31 and the elastic member 34 are vertically arranged in the installation groove. In the open state of the solenoid valve assembly 3, the magnetic member 31 moves upward under the electromagnetic force, compresses the elastic member 34, and drives the second seal 32 to rise from the water inlet of the second pipeline 2, thereby conducting the first pipeline 1 and the second pipeline 2; in the closed state of the solenoid valve assembly 3, under the downward pressure of the compressed state of the elastic member 34 and the downward gravity of the magnetic member 31 itself, the second seal 32 can be tightly pressed on the water inlet of the second pipeline 2, effectively disconnecting the first pipeline 1 and the second pipeline 2, with good reliability and effectively preventing the phenomenon that the water outlet device cannot seal the water.

[0047] Specifically, as Figure 3 shown, the solenoid valve assembly 3 further includes a second fixing member 35, which is fixedly connected to the water outlet end 11, and fixes the first fixing member 33 between the water outlet end 11 and the second fixing member 35, with reliable fixation and not easy to loosen; optionally, the water outlet end 11 and the second fixing member 35 are fixedly connected by a fastener, and the fastener includes at least one of a bolt and a pin, which is convenient for assembly and tightly connected; in some embodiments, a plurality of first connection holes are provided on the water outlet end 11, and a plurality of second connection holes are provided on the second fixing member 35, and the plurality of first connection holes and the plurality of second connection holes are connected by fasteners in a one-to-one correspondence, with good fixing reliability; in this embodiment, as Figure 1 shown, four first connection holes are evenly distributed on the water outlet end 11, and four uniformly arranged second connection holes are provided on the second fixing member 35. Each first connection hole is fixedly connected to a second connection hole by a bolt, effectively fixing the first fixing member 33 and the second fixing member 35.

[0048] Specifically, as Figure 3As shown, the solenoid valve assembly 3 further includes an electrical connector 36. The electrical connector 36 is sleeved outside the installation groove and is used to provide electromagnetic force for the magnetic member 31. In this embodiment, the electrical connector 36 includes a conductive insert and a wire coil assembly. The wire coil assembly includes a wire coil housing, internal wires, and an external inverted U-shaped bracket. When the wire coil assembly is energized, the armature member can be attracted to the top, causing the elastic member 34 to be compressed, and the solenoid valve assembly 3 is in an open state. When the wire coil assembly is de-energized, the armature member presses downward on the second seal 32, and at the same time, the elastic member 34 provides a part of the elastic force to the armature member, further pressing downward on the second seal 32, and the solenoid valve assembly 3 is in a closed state, improving the sealing reliability of the water inlet of the second pipeline 2.

[0049] Specifically, as Figure 5 shown, a sealing groove 110 is provided inside the water outlet end 11 of the first pipeline 1. A third seal 6 is provided in the sealing groove 110. The water outlet end 11 of the first pipeline 1 is hermetically connected to the first fixing member 33 through the third seal 6, so that the water outlet end 11 of the first pipeline 1 forms a sealed cavity. The magnetic member 31 synchronously drives the second seal 32 to perform a linear motion in this sealed cavity to connect or disconnect the first pipeline 1 and the second pipeline 2. In this embodiment, the bottom of the first fixing member 33 is provided with a sealing edge extending towards the second pipeline 2, and the inner side wall of the water outlet end 11 is provided with a sealing boss. The sealing groove 110 is arranged on this sealing boss. The sealing edge can abut against the sealing boss, so that the gap between the sealing edge and the sealing boss is filled by the third seal 6 in the sealing groove 110, thereby effectively sealing the water outlet end 11 and preventing water leakage.

[0050] Optionally, the third seal 6 is an elastic seal, which can enhance the sealing performance between the first fixing member 33 and the water outlet end 11 in the solenoid valve assembly 3, prevent water from flowing out between the first fixing member 33 and the water outlet end 11 and causing water leakage, and also prevent water from contacting the electrical connector 36 and even causing a short circuit to damage the water outlet device, improving the overall safety of the water outlet device. In this embodiment, the third seal 6 is an annular sealing ring with good sealing performance.

[0051] Specifically, as Figure 6As shown, the sealing assembly 5 includes a first seal 51 and a sealing cover 52. After the sealing cover 52 is connected to the branch pipe 4, a receiving cavity 53 is formed, and the first seal 51 is movably disposed in the receiving cavity 53. A through hole 520 is formed in the sealing cover 52. When there is water pressure in the second pipeline 2, the first seal 51 can move under the action of the water pressure to be sealingly connected to the through hole 520. When there is no water pressure in the second pipeline 2, the first seal 51 can move under the action of gravity until the branch pipe 4 communicates with the through hole 520, so that the inside of the second pipeline 2 is at the same atmospheric pressure as the outside, prompting the water flow in the water outlet to flow out in time under its own gravity, avoiding the phenomenon that water still drips or flows out after the solenoid valve assembly 3 closes one end for a long time, and further preventing the user from being scalded by the dripping water when moving the hand away after receiving water.

[0052] Specifically, as Figure 6 shown, the inner diameter of the through hole 520 is smaller than the maximum diameter of the first seal 51, which can play a role in limiting and preventing detachment, preventing the first seal 51 from detaching from the through hole 520 under the action of water pressure, and having good stability.

[0053] Specifically, as Figure 6 shown, the branch pipe 4 is provided with a limiting portion 41. When there is no water pressure in the second pipeline 2, the first seal 51 can abut against the limiting portion 41 under the action of gravity, that is, the inner diameter of the branch pipe 4 at the limiting portion 41 is smaller than the maximum diameter of the first seal 51. The limiting portion 41 plays a role in preventing detachment, preventing the first seal 51 from falling off from the branch pipe 4 into the second pipeline 2, avoiding the failure of the first seal 51, and improving the structural reliability of the sealing assembly 5.

[0054] Specifically, as Figure 6As shown, the first seal 51 includes a moving part 510 and an elastic sealing part 511. The elastic sealing part 511 is fixedly connected to one end of the moving part 510 away from the second pipeline 2, so that the first seal 51 functions as a one-way seal. When there is water pressure in the second pipeline 2, the elastic sealing part 511 can abut against the inner wall of the sealing cover 52 under the action of water pressure, that is, the elastic sealing part 511 abuts against the side wall of the through hole 520 to seal the through hole 520, ensuring that the water outlet pipeline 2 can discharge water normally, with good stability and high safety. When there is no water pressure in the second pipeline 2, that is, when the solenoid valve assembly 3 is closed, under the action of the self-gravity of the first seal 51, the elastic sealing part 511 moves obliquely downward with the moving part 510, so that the elastic sealing part 511 can be separated from the inner wall of the sealing cover 52, that is, the side wall of the through hole 520, to connect the branch pipe 4 with the through hole 520, making the second pipeline 2 and the outside at the same atmospheric pressure. The water flow in the second pipeline 2 can flow out of the water outlet of the second pipeline 2 in time under the action of its own gravity, avoiding the phenomenon that water droplets still drip after the solenoid valve assembly 3 has been closed for a period of time, improving the user experience, and especially greatly improving the safety when using hot water.

[0055] Specifically, as Figure 7 shown, at least one end of the first seal 51 is provided with a guiding part 512. The guiding part 512 can extend into the limiting part 41 or the through hole 520, preventing the first seal 51 from shifting during movement and resulting in poor sealing, which is beneficial to improving the sealing reliability and safety when the second pipeline 2 discharges water normally.

[0056] In this embodiment, the first seal 51 is provided with two guiding parts 512, which are respectively located at both ends of the first seal 51. The outer diameter of the guiding part 512 is smaller than the major diameter of the moving part 510. Among them, the outer diameter of the guiding part 512 close to the water outlet pipeline 2 is smaller than the inner diameter of the limiting part 41, so that the guiding part 512 at this end can smoothly extend into the limiting part 41, and the outer diameter of the other guiding part 512 is smaller than the inner diameter of the through hole 520, so that the guiding part 512 at this end can smoothly extend into the through hole 520, thereby being able to limit the moving direction of the first seal 51 and enabling the elastic sealing part 511 to accurately abut against the side wall of the through hole 520 to seal the through hole 520 when discharging water, with good reliability.

[0057] In addition, in some embodiments, a receiving groove may be provided at one end of the moving portion 510 away from the second pipeline 2, and the elastic sealing portion 511 is installed in the receiving groove. Moreover, the elastic sealing portion 511 may be configured as an elastic sealing portion 511 with a preset thickness, that is, the portion of the elastic sealing portion 511 protruding from the receiving groove (or one end of the moving portion 510) can surround a part of the guiding portion 512, so that when there is water pressure in the second pipeline 2, the elastic sealing portion 511 can be in interference fit with the side wall of the through hole 520, further improving the sealing reliability.

[0058] Specifically, in some embodiments, as Figure 7 shown, at least one air guiding boss 513 is provided on the side of the moving portion 510 close to the second pipeline 2. Further, the air guiding boss 513 is disposed at the connection between the moving portion 510 and the guiding portion 512, and an air guiding channel is formed between adjacent air guiding bosses 513. When the solenoid valve assembly 3 is closed, that is, when there is no water pressure in the second pipeline 2, the outside air can flow into the second pipeline 2 along the through hole 520, the gap between the moving portion 510 and the sealing cover 52, the air guiding channel between the air guiding bosses 513, and the branch pipe 4. The air guiding channel increases the flow space of the air flow inside the sealing assembly 5, which is beneficial to improving the reliability and stability of the communication between the second pipeline 2 and the outside, and reducing the risk of accidental blockage. In this embodiment, six air guiding bosses 513 are provided on the side of the moving portion 510 close to the second pipeline 2, and the six air guiding bosses 513 are evenly distributed on one side of the moving portion 510 along the circumferential direction of the branch pipe 4, greatly improving the reliability of the communication between the second pipeline 2 and the outside and the air flow uniformity.

[0059] Specifically, the acute angle formed between the axial direction of the branch pipe 4 and the axial direction of the second pipeline 2 is 15 - 75°. On the one hand, the first seal 51 can be affected by gravity and automatically fall when there is no water pressure in the second pipeline 2, thus conducting the second pipeline 2 and the outside. On the other hand, the first seal 51 is easily affected by the impact force of the water flow in the second pipeline 2 and moves obliquely upward, thereby effectively sealing the through hole 520 and isolating the second pipeline 2 from the outside. In some embodiments, the acute angle formed between the axial direction of the branch pipe 4 and the axial direction of the second pipeline 2 is 45 - 75°, improving the flatness of the slope of the branch pipe 4. The water pressure required to seal the branch pipe 4 during water discharge is lower, that is, it can push the sealing assembly 5 to move for sealing at a lower water pressure, with good water discharge convenience and easy and labor-saving use. Exemplarily, in this embodiment, the acute angle formed between the axial direction of the branch pipe 4 and the axial direction of the second pipeline 2 is 70°, which can reliably perform one-way sealing on the through hole 520 and the second pipeline 2 with the branch pipe 4.

[0060] In addition, the branch pipe 4 is arranged towards the inside or the side of the device with the water outlet device, avoiding the direction towards the user, preventing the hot steam generated when hot water comes out from scalding the user, and improving safety.

[0061] Specifically, as Figure 1 shown, at least one guiding convex platform 21 is provided on the inner wall of the water outlet of the second pipeline 2. The guiding convex platform 21 protrudes from the inner wall of the second pipeline 2 towards the central axis of the second pipeline 2, and the guiding convex platform 21 extends along the axial direction of the second pipeline 2, that is, the guiding convex platform 21 has a preset length in the axial direction of the second pipeline 2. A water guiding channel is formed between adjacent guiding convex platforms 21, which plays a role in guiding the flow, making the water shape of the outlet water more beautiful, further improving the convenience of the water flow flowing down, and further reducing the residual amount of water in the second pipeline 2, with a better anti-scalding effect; in this embodiment, eight guiding convex platforms 21 are provided on the inner wall of the water outlet of the second pipeline 2, and the eight guiding convex platforms 21 are evenly distributed on the inner wall of the water outlet along the circumferential direction of the second pipeline 2, with a good guiding effect.

[0062] During operation, the conductive insert is connected to the input voltage, that is, the coil assembly is powered on, and electrical energy is converted into magnetic energy, sucking the magnetic armature part to the top. During the upward movement of the armature part, the second sealing member 32 is driven to move upward synchronously, so that the first pipeline 1 and the second pipeline 2 are completely communicated. Water will flow in from the water inlet end of the first pipeline 1 and finally flow out from the water outlet of the second pipeline 2; among them, at the branch pipe 4 on the second pipeline 2, under the impact of the water flow, the moving part 510 drives the elastic sealing part 511 to move obliquely upward synchronously under the action of the water pressure, so that the elastic sealing part 511 abuts against and squeezes the side wall of the through hole 520 of the sealing cover 52 to seal the through hole 520, isolating the second pipeline 2 from the outside, ensuring that the water flow does not flow out from the branch pipe 4, but stably flows out from the water outlet of the second pipeline 2.

[0063] When there is no voltage input to the conductive insert, that is, the coil assembly loses magnetism, the armature part moves downward under the action of gravity and the elastic force of the elastic member 34. The second sealing member 32 is pressed onto the water inlet of the second pipeline 2 under the action of the gravity of the armature part and the elastic force of the elastic member 34, thus closing the water outlet; at this time, there is no water flow in the second pipeline 2, that is, there is no water impact force in the second pipeline. The first sealing member 51 will move obliquely downward under the action of its own gravity, and the elastic sealing part 511 is separated from the side wall of the through hole 520, so that the atmospheric pressure enters the second pipeline 2 through the through hole 520, the gap between the moving part 510 and the sealing cover 52, the air guiding channel and the branch pipe 4, making the second pipeline 2 at the same atmospheric pressure as the outside. The residual water at the water outlet will flow out from the water outlet in time under the action of gravity, and there is no water residue at the water outlet, preventing the phenomenon that water still drips after the water outlet device is closed for a period of time.

[0064] Embodiment 2

[0065] The difference between this embodiment and Embodiment 1 is that, as Figure 4 shown, there is at least one raised structure on the third seal 6, which can further improve the sealing reliability of the third seal 6; in this embodiment, the third seal 6 is provided with two annular raised structures, which are respectively located at the top and bottom of the third seal 6 to respectively enhance the sealing reliability between the third seal 6 and the first fixing member 33 and the sealing reliability between the third seal 6 and the water outlet end 11; the rest is the same as Embodiment 1.
