Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, and in particular to a water nozzle structure and a water purifier comprising the same. Background Art

[0002] As commercial water purifiers become more and more popular, some problems have been exposed in the market, especially the structure of the water outlet spout. Every time the user takes water, there will always be dripping. In order to solve this problem, the industry has added an exhaust pipe or exhaust port to the spout, which can effectively use the external environmental air pressure to discharge the residual water in the spout. However, on the basis of the exhaust pipe or exhaust port on the spout, when the water flow in the spout is too large, it is easy for the water to overflow from the exhaust pipe or exhaust port. On the one hand, this causes a waste of water resources, and on the other hand, it increases the difficulty of cleaning for users. If the overflowed water is not cleaned in time, the bacteria in the air will remain in the water on the spout or water purifier after the overflow and reproduce and form mold, which not only affects drinking safety, but also makes the user experience worse. Therefore, there is a need for a spout structure that can solve the above problems. Utility Model Content

When the water flow is normal, the one-way valve assembly can ensure that air enters the exhaust pipe normally, so as to exclude the residual water flow in the faucet structure when the faucet structure is used normally, and prevent bacteria in the air from multiplying in the residual water flow in the faucet structure. The seal is positioned by a protrusion to prevent the water flow from overflowing the one-way valve assembly and entering the water purifier when the seal falls off, thereby improving the reliability of the faucet structure.

[0008] Preferably, the one-way valve assembly further includes a first guide portion, the first guide portion is connected to the valve core along a vertical direction, and the first guide portion extends into the exhaust pipe.

[0009] In this solution, the first guide portion is provided to limit the moving direction of the valve core during its movement, thereby preventing the valve core from being unable to return to its original position after movement and thereby blocking the air inlet of the cavity.

[0010] Preferably, a limiting portion is provided in the cavity, the limiting portion is provided in a horizontal direction, and the limiting portion is used to position the valve core and to keep the cavity and the exhaust pipe connected at all times.

[0011] In this solution, a limit portion is provided to prevent the valve core from blocking the air outlet of the cavity when it moves, thereby ensuring the exhaust and water removal function when the water flow is normal.

[0012] Preferably, the limiting portion is a mesh structure and has a plurality of through holes, and the air inlet and the air outlet of the cavity are connected through the plurality of through holes.

[0013] In this solution, the above arrangement allows the outside air to enter the cavity smoothly, thus avoiding the situation where exhaust cannot be performed when the limiting part positions the valve core.

[0015] In this solution, a second guide portion is provided so that the valve core can be reset in time after moving, thereby avoiding the situation where the valve core is offset and blocks the air inlet or outlet of the cavity.

[0016] Preferably, the exhaust pipe is located at a side of the faucet structure and the exhaust pipe is connected to the faucet structure via a connecting piece.

[0017] In this solution, a connector is provided to support the exhaust pipe and the one-way valve assembly, and the faucet structure can be connected to the water path in the water purifier without avoiding the exhaust pipe, thereby ensuring that the water flow rate is not affected.

[0048] The following is a preferred embodiment, and the accompanying drawings are used to more clearly and completely illustrate the utility model. This embodiment provides a faucet structure 1, the specific structure is as follows Figure 1 , Figure 2 and Figure 3 As shown, the faucet structure 1 is arranged at the water outlet of the water purifier, and the faucet structure 1 is connected to an exhaust pipe 2. The faucet structure 1 includes:

[0049] The one-way valve assembly 3 is connected to the exhaust pipe 2. The one-way valve assembly 3 includes a cavity 31 and a valve core 32 movably connected in the cavity 31. A groove is provided at the connection between the valve core 32 and the air inlet of the cavity 31. A sealing member 321 is provided in the groove and the sealing member 321 protrudes from the outer surface of the valve core 32. A protrusion for positioning the sealing member 321 is provided in the groove.

[0050] Specifically, the exhaust pipe 2 is connected to the faucet structure 1, and the exhaust pipe 2 is a cylindrical structure. This embodiment is described with the exhaust pipe 2 being a silicone tube, but it is not limited thereto. In other embodiments, the exhaust pipe 2 can also be a high-temperature resistant PE tube. The exhaust pipe 2 is provided to connect the faucet structure 1 with the external environment, so that the air pressure in the faucet structure 1 is consistent with the air pressure of the external environment, and the water remaining in the faucet structure 1 after use is discharged in time through the air pressure of the external environment to avoid contact with bacteria in the air and reproduction. In addition, when hot water flows out of the water purifier, the exhaust pipe 2 can discharge the steam of the hot water to prevent the water flow from scalding the user who takes water.

[0051] On this basis, the present embodiment further provides a one-way valve assembly 3, which is provided at the end of the exhaust pipe 2 and is higher than the faucet structure 1, so that when the water flow rate in the faucet structure 1 is low, the valve core 32 of the one-way valve assembly 3 can be smoothly exhausted without pushing it. The cavity 31 of the one-way valve assembly 3 is a cylindrical structure, and the valve core 32 is a sphere made of plastic. When the water flow rate is too fast, the water flows in from the connection between the faucet structure 1 and the exhaust pipe 2 and pushes the valve core 32 to move. When the valve core 32 moves to the air inlet of the cavity 31, it abuts against the inner wall of the cavity 31, and then cuts off the air inlet of the cavity 31 through the sealing member 321. At this time, no air is taken into the exhaust pipe 2, and only the water is discharged through the faucet structure 1, until the water flow rate is weakened and the valve core 32 falls to open the air inlet of the cavity 31. The seal 321 can effectively prevent water from overflowing when in contact with the inner wall of the cavity 31, thereby preventing problems with the internal cleanliness of the water purifier after the water overflows, and preventing the overflowed water from generating mold.

[0052] It should be noted that the protrusion provided in the groove in this embodiment is located at the bottom of the groove, the protrusion extends in the vertical direction and is flush with the outer surface of the valve core 32, the sealing member 321 is a sealing ring made of rubber material, and a groove is provided on the sealing ring corresponding to the protrusion to cooperate with the protrusion to realize the positioning of the sealing member 321. The sealing member 321 is positioned by the protrusion to prevent the water flow from overflowing the one-way valve assembly 3 and entering the water purifier when the sealing member 321 falls off, thereby improving the reliability of the faucet structure 1.

[0053] It can be understood that the grooves, protrusions and trenches are all annular structures to effectively block the water flow around the air inlet of the cavity 31.

[0054] In other embodiments, the valve core 32 may also be in other shapes, such as a cylindrical structure. Its purpose is also to use water flow to push the valve core 32 to move and block the air inlet of the cavity 31 to achieve blocking of water flow, which will not be elaborated here.

[0055] In another embodiment, the one-way valve assembly 3 can also be arranged between the exhaust pipe 2 and the faucet structure 1, that is, the exhaust pipe 2 is located above the one-way valve assembly 3. At this time, when the water flow rate is greater than the drainage capacity of the faucet structure 1, the one-way valve assembly 3 will be triggered. Compared with the structure in which the one-way valve assembly 3 is arranged above the exhaust pipe 2, it is suitable for users with smaller water intake, and the position of the one-way valve assembly 3 can be adjusted according to the actual needs of the user.

[0056] In this embodiment, the one-way valve assembly 3 further includes a first guide portion 33 , which is connected to the valve core 32 along a vertical direction and extends into the exhaust pipe 2 .

[0057] Specifically, the first guide portion 33 is located at the bottom of the valve core 32 and extends vertically into the exhaust pipe 2. The first guide portion 33 is a cylindrical structure and is integrally formed with the valve core 32. The first guide portion 33 is provided to limit the moving direction of the valve core 32 during the movement of the valve core 32 to prevent the valve core 32 from being unable to return to its original position after movement and blocking the air inlet of the cavity 31.

[0058] In this embodiment, a limiting portion 34 is disposed in the cavity 31 . The limiting portion 34 is disposed in a horizontal direction. The limiting portion 34 is used to position the valve core 32 and to keep the cavity 31 and the exhaust pipe 2 connected at all times.

[0059] Specifically, the limit portion 34 is located in the middle area of ​​the cavity 31, the valve core 32 is located above the limit portion, the cavity 31 is a split cavity and is connected by rotational melting, wherein the limit portion 34 is located in the lower part of the split cavity, and the limit portion 34 is provided so that the valve core 32 maintains a certain distance from the air outlet of the cavity 31 to avoid the valve core 32 blocking the air outlet and causing the exhaust pipe 2 to be unable to intake air, thereby ensuring the exhaust and water removal function when the water flow is normal.

[0060] In this embodiment, the limiting portion 34 is a mesh structure and has a plurality of through holes, and the air inlet and the air outlet of the cavity 31 are connected through the plurality of through holes.

[0061] Specifically, the limiting portion 34 is a plate and has a plurality of through holes. When the water flow does not push the valve core 32 to move, that is, under normal circumstances, the air from the external environment flows into the exhaust pipe 2 from the air inlet of the cavity 31 through the through holes and the air outlet in sequence, thereby avoiding the situation where the exhaust pipe 2 cannot be exhausted when the limiting portion 34 positions the valve core 32.

[0062] The first guide portion 33 extends into the through hole, and the through hole is larger than the first guide portion 33 , so that the movement of the valve core 32 can be limited through the through hole.

[0063] In this embodiment, the one-way valve assembly 3 further includes a second guide portion 35 , which is arranged along the vertical direction and extends into the through hole.

[0064] Specifically, a second guide portion 35 is provided at the bottom of the valve core 32, and a plurality of second guide portions 35 are provided and extend into different through holes respectively, and the second guide portion 35 is provided integrally with the valve core 32. By providing the second guide portion 35, the valve core 32 can be reset in time after moving, so as to avoid the situation where the valve core 32 is offset and blocks the air inlet or outlet of the cavity 31. In this embodiment, the first guide portion 33 and the second guide portion 35 are both made of plastic material so as to follow the movement of the valve core 32.

[0065] In other embodiments, the first guide portion 33 may also be respectively arranged at the top and bottom of the valve core 32, the first guide portion 33 located at the top of the valve core 32 extends into the air inlet of the cavity 31, and the first guide portion 33 located at the bottom of the valve core 32 extends into the exhaust pipe 2, so as to further improve the stability of the valve core 32 during movement and prevent it from being unable to reset after movement.

[0066] In this embodiment, the exhaust pipe 2 is located at the side of the faucet structure 1 and the exhaust pipe 2 is connected to the faucet structure 1 through a connecting piece 4 .

[0067] Specifically, the connector 4 is an "L"-shaped structure and is located on the side of the faucet structure 1 away from the water path of the water purifier. The end of the "L"-shaped structure used for connecting with the faucet structure 1 is provided with an external thread, and the faucet structure 1 is correspondingly provided with a threaded hole, which is screwed to ensure the sealing of the connection between the connector 4 and the faucet structure 1. The water path of the water purifier is connected to the top port of the faucet structure 1 through a silicone tube, while the exhaust pipe 2 and the one-way valve assembly 3 are located on the side of the faucet structure 1 and are arranged in the vertical direction. On the one hand, it is ensured that the height of the exhaust pipe 2 is higher than the faucet structure 1. On the other hand, the exhaust pipe 2 is arranged on the side of the faucet structure 1 on the basis of the original connection between the water path and the faucet structure 1, which can avoid changing the original connection method between the water path and the faucet structure 1 and reduce the difficulty of improvement. The faucet structure 1 is connected to the water path in the water purifier without avoiding the exhaust pipe 2, thereby ensuring that the water flow rate is not affected.

[0068] In this embodiment, a positioning portion 5 is further provided at the connection between the one-way valve assembly 3 and the connector 4 and the exhaust pipe 2, and the positioning portion 5 is used to position the one-way valve assembly 3 and the connector 4 along the connection direction.

[0069] Specifically, the positioning portion 5 is a conical structure and is arranged in an annular manner on the outer peripheral side of the cavity 31 for connection with the exhaust pipe 2 and the outer peripheral side of the connecting piece 4 for connection with the exhaust pipe 2. The end with a smaller size of the conical structure is arranged toward the direction of connection with the exhaust pipe 2, while the end with a larger size of the conical structure is arranged away from the exhaust pipe 2, so as to limit the connection direction by the end with a larger size of the conical structure, prevent the one-way valve assembly 3 or the connecting piece 4 from loosening after connection with the exhaust pipe 2, and improve the reliability of the structure.

[0070] In addition, after the end of the conical structure with a larger size is connected to the exhaust pipe 2 made of silicone material, it extends toward the inner wall of the exhaust pipe 2 and seals the connection, which can also play a certain sealing role to prevent water from overflowing from the connection.

[0071] like Figure 4 As shown, in this embodiment, a warning light 6 is provided at the water outlet of the faucet structure 1 .

[0072] Specifically, the warning light 6 is a ring light and is arranged around the water outlet of the faucet structure 1. The warning light 6 is divided into two colors and each color represents the temperature of the outflowing water, for example, red and blue, red represents hot water, and blue represents normal temperature water. The warning light 6 is connected to the control panel of the water purifier through a wire to provide a warning according to the actual water temperature of the outflowing water in the water path of the water purifier. In addition, the warning light 6 can also enable the user to quickly find the water outlet in a dim environment, avoiding the situation where the user cannot find the water outlet in time when the light is not turned on and the hot water flows out of the water purifier, causing the user's hands to be scalded, so as to improve the user's experience.
