Description

Technical Field

[0001] The utility model relates to the technical field of electric water faucets, in particular to a water outlet pipe component of an electric water faucet and the electric water faucet. Background Art

[0002] Electric water faucets can heat water quickly, providing convenience for users' lives.

[0003] Currently, electric faucets have a silicone tube installed inside the outlet elbow, connected to the water outlet of the inner tank. This prevents the water heated by the electric heating tube from coming into direct contact with the metal outlet elbow. In the event of electrical leakage and charged water, the water resistance is greater when passing through the longer outlet elbow, reducing the leakage current and the risk of leakage. However, some electric faucets used in bathrooms lack a longer outlet elbow, resulting in a shorter water path from the inner tank to the outlet, resulting in higher leakage current and increasing the risk of leakage.

[0041] like Figure 1-Figure 3As shown, this embodiment provides a water outlet pipe assembly for an electric faucet, comprising a housing 1 and an inner pipe sleeve 22. The housing 1 is provided with a water inlet 11 and a water outlet 12 at either end. An inner pipe 21 is provided within the housing 1, extending axially along the housing 1 and communicating with the water inlet 11. The inner pipe 21 and the inner pipe sleeve 22 cooperate to form a long outlet flow path within the housing 1. This allows water to enter the housing 1 through the water inlet 11, flow through the long outlet flow path, and then exit through the water outlet 12, increasing the water's electrical resistance and reducing leakage current, thereby providing a safety measure and mitigating the risk of leakage.

[0042] In one embodiment, the end of the inner tube 21 near the water inlet 11 is connected to the inner wall of the housing 1, and the inner tube sleeve 22 is inserted into the housing 1 from the end near the water outlet 12. The inner tube sleeve 22 is sleeved outside the inner tube 21, leaving a first radial gap 13 between the inner wall of the inner tube sleeve 22 and the outer wall of the inner tube 21, and a second radial gap 14 between the outer wall of the inner tube sleeve 22 and the inner wall of the housing 1. The first radial gap 13 is connected to the second radial gap 14, and the water outlet 12 is connected to the second radial gap 14 to form a sequentially connected water outlet channel, thereby extending the flow path of the outlet water flow, increasing the water outlet resistance, and significantly reducing the leakage current during water outlet, thereby significantly reducing the leakage hazard. In addition, the overall structure of the outlet pipe assembly is compact, realizing the integration of the anti-electrical wall function in a relatively short electric water faucet, improving the safety of use.

[0043] The first radial gap 13 and the second radial gap 14 can be connected through a connecting hole, or the inner tube 21 and the inner tube sleeve 22 can be spaced apart at both ends along the axial direction to achieve communication.

[0044] In one embodiment, a first axial gap 15 is left between the inner tube sleeve 22 and the inner tube 21 at the end near the water inlet 11, and a second axial gap 16 is left at the end near the water outlet 12. The second axial gap 16 connects the inner tube 21 and the first radial gap 13, the first axial gap 15 connects the first radial gap 13 and the second radial gap 14, and the water outlet 12 connects to the second radial gap 14. By fixedly connecting the ends of the inner tube sleeve 22 and the inner tube 21 that are separated from each other to the housing 1 and providing axial gaps at both ends of the inner tube 21 and the inner tube sleeve 22 along the axial direction, the first radial gap 13 and the second radial gap 14 are connected, resulting in a compact structure and no need to process additional connecting holes, thereby reducing costs.

[0045] In one embodiment, the outer wall of the inner sleeve 22 is provided with a spiral structure 221, which abuts against the inner wall of the housing 1 to form a spiral flow channel within the second radial gap 14. Specifically, the spiral protrusion structure provided on the outer wall of the inner sleeve 22 forms a spiral flow channel within the second radial gap 14, further extending the path of the water outlet channel, increasing the resistance of the water, further reducing leakage current, and minimizing leakage damage.

[0046] In one embodiment, an outer edge disk 211 having a diameter larger than that of the inner tube 21 is provided at one end of the inner tube 21 away from the water outlet 12 . The outer edge disk 211 is connected to the inner wall of the shell 1 to fix the inner tube 21 in the shell 1 .

[0047] In one embodiment, the inner tube 21 is integrally formed with the housing 1. The inner tube 21 and the housing 1 are integrally formed, eliminating the need for assembly steps to connect the inner tube 21 and the housing 1. Furthermore, no additional seals are required, ensuring a tight seal at the connection between the inner tube 21 and the housing 1. This makes assembly more convenient and reduces costs.

[0048] Of course, in other embodiments, the outer edge disk 211 and the inner wall of the shell 1 can be detachably connected by screw connection or other means.

[0049] In one embodiment, the water outlet 12 is arranged on the circumference of the shell 1. In this arrangement, the axis of the water outlet 12 is arranged perpendicular to the axis of the shell 1, the water outlet pipe assembly of the electric faucet is arranged horizontally, and the water flows out in a vertical downward direction.

[0050] One end of the inner tube sleeve 22 is provided with a closure cap 222, which is sealed to the end of the housing 1 near the water outlet 12. One end of the inner tube sleeve 22 is provided with an opening for insertion between the housing 1 and the inner tube 21, forming a first radial gap 13 and a second radial gap 14 to define a water outlet channel. The other end is provided with a closure cap 222. After the inner tube sleeve 22 is inserted into the housing 1 and in place, the closure cap 222 directly seals the housing 1 along one axial end, eliminating the need for a separate closure member to seal the housing 1. This reduces the number of components in the outlet pipe assembly of the electric faucet and simplifies the assembly process.

[0051] Of course, in other embodiments, the water outlet 12 can also be set at one axial end of the shell 1, and the axis of the water outlet 12 coincides with the axis of the water outlet pipe assembly of the electric faucet, and the water flows out in a horizontal direction and flows downward under the action of gravity.

[0052] In one embodiment, the water inlet 11 is disposed circumferentially of the housing 1, and a waterproof plug 23 is disposed at one end of the housing 1 away from the inner tube sleeve 22. The water inlet 11 is disposed circumferentially of the housing 1, i.e., the axis of the water inlet 11 is perpendicular to the axis of the housing 1 and coincides with the axis of the faucet body 100, making connection with the body 100 more convenient.

[0053] The water inlet 11 and the water outlet 12 on the housing 1 can be specifically arranged according to the structure of the body 100 of the electric faucet. The water inlet 11 can also be arranged at the other end of the housing 1 along the axial direction.

[0054] The shell 1, the inner tube 21, the inner tube sleeve 22 and the waterproof plug 23 are all made of nylon; of course, other high-temperature resistant insulating materials can also be used to ensure that when the water in the water outlet pipe assembly of the electric water faucet is charged, the water outlet pipe assembly of the electric water faucet itself is not charged and will not conduct leakage electricity to other components such as the fuselage 100.

[0055] In one embodiment, the outlet pipe assembly of the electric faucet further includes a sealing assembly comprising a first sealing ring 31 and a second sealing ring 32. The first sealing ring 31 is disposed between the closure cover 222 and the inner wall of the housing 1, and the second sealing ring 32 is disposed between the waterproof plug 23 and the inner wall of the housing 1. The first sealing ring 31 and the second sealing ring 32 ensure the sealing of both ends of the outlet pipe assembly along the axial direction of the electric faucet to prevent water leakage.

[0056] Specifically, the closure cover 222 is circumferentially provided with a first sealing groove 2221, and a first sealing ring 31 is disposed within the first sealing groove 2221. Furthermore, two first sealing grooves 2221 are spaced apart, with a first sealing ring 31 disposed within each first sealing groove 2221. The waterproof plug 23 is circumferentially provided with a second sealing groove 231, and a second sealing ring 32 is disposed within the second sealing groove 231. Furthermore, two second sealing grooves 231 are spaced apart, with a second sealing ring 32 disposed within each second sealing groove 231. The provision of two first sealing rings 31 and two second sealing rings 32 ensures the sealing of both ends of the outlet pipe assembly of the electric faucet along the axial direction.

[0057] In one embodiment, a water outlet channel is provided at one end of the housing 1 near the water outlet 12. A water inlet chamber 17 is provided at one end of the housing 1 near the water inlet 11. The water inlet chamber 17 communicates with the water inlet 11 and the inner tube 21. Because the diameter of the water outlet channel, formed by the gap between the inner tube 21, the inner tube sleeve 22, and the housing 1, is relatively small, if water entering the housing 1 through the water inlet 11 directly enters the water outlet channel, the pressure is relatively high, which could easily cause the first sealing ring 31 and the second sealing ring 32 at both ends of the electric faucet's water outlet pipe assembly to fail, thereby affecting the sealing performance of the electric faucet's water outlet pipe assembly.

[0058] Specifically, the length of the inner tube 21 is less than half the length of the shell 1. While increasing the water flow path of the water outlet channel, it ensures the volume of the water inlet chamber 17 to avoid excessive pressure in the shell 1, which affects the service life of the first sealing ring 31 and the second sealing ring 32.

[0059] In one embodiment, a connecting lug 19 is provided on the outer periphery of the housing 1 , and the water outlet pipe assembly of the electric water faucet is fixed by the connecting lug 19 .

[0060] like Figure 4 and Figure 5 As shown, this embodiment also provides an electric water faucet, including a body 100 and the above-mentioned water outlet pipe assembly of the electric water faucet, the water outlet pipe assembly of the electric water faucet is arranged in the water outlet pipe housing 102, and the water inlet 11 is connected to the body 100.

[0061] Specifically, the water outlet housing 102 includes a bottom housing 1021 and a top cover 1022. The top cover 1022 is mounted on the bottom housing 1021 and is detachably connected to the bottom housing 1021. A connection port is provided on a side of the bottom housing 1021 near the inner liner 101. The body 100 includes the inner liner 101. The connection port is connected to one end of the inner liner 101. The water inlet pipe 18 provided at the water inlet 11 extends from the connection port and is sealedly connected to the outlet of the inner liner 101.

[0062] In order to ensure the sealing between the water inlet pipe 18 and the outlet of the inner tank 101, two third sealing grooves 181 are arranged at intervals on the outer periphery of the water inlet pipe 18, and a third sealing ring 33 is arranged in each third sealing groove 181. The third sealing ring 33 is located between the water inlet pipe 18 and the outlet of the inner tank 101 to achieve a sealed connection.

[0063] When connecting the water outlet pipe assembly of the electric faucet to the body 100, the top cover 1022 is removed, and the water outlet pipe assembly of the electric faucet is placed in the bottom shell 1021. Both ends of the connecting lug 19 are provided with connecting holes 191. The water outlet pipe assembly of the electric faucet is fixed in the bottom shell 1021 by two fastening screws, and then the top cover 1022 is covered on the bottom shell 1021.

[0064] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The specific contents of the above-mentioned specific embodiments only express several embodiments of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the appended claims.
