Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to a water outlet component and a water heater. Background Technology

[0002] An electric water heater is an appliance that uses electricity to heat water. It includes an inner tank for water storage, an electric heating element, an inlet assembly, and an outlet assembly. The electric heating element is installed in the inner tank to heat the water in the inner tank. External water enters the inner tank through the inlet assembly and then flows out through the outlet assembly.

[0003] To prevent excessive pressure in the inner tank, a safety valve is installed in the water inlet assembly. When the pressure inside the inner tank exceeds the limit of the safety valve, the safety valve will open to release pressure normally, and the water in the inner tank will drip out through the safety valve.

[0004] In existing electric water heaters, the safety valve frequently opens during use, causing water to drip and release pressure, which can easily affect the usage environment and reduce the user experience. Utility Model Content

[0005] One of the technical problems solved by this utility model is to provide a water outlet component that can effectively solve the technical problem of frequent opening of safety valves.

[0006] The second technical problem solved by this utility model is to provide a water heater that can effectively solve the technical problem of frequent opening of the safety valve.

The driven tube is provided with a liquid inlet, which is connected to the liquid outlet through the inner cavity of the driven tube and the inner cavity of the driving tube. The driving tube and the driven tube are connected in a transmission manner within the outer tube. During the rotation of the driving tube, it can drive the driven tube to adjust the distance of the liquid inlet extending out of the outer tube.

[0012] The active tube and / or the driven tube are sealed to the inner wall of the outer tube.

[0013] The water outlet component described in this utility model has the following advantages compared with the prior art:

[0014] It is understood that there is a space between the water level and the top of the inner tank, containing air. During heating, the water and air inside the inner tank expand, increasing the pressure inside. When the aforementioned water outlet assembly is used in a water heater, the active and passive pipes inside the outer casing work together. Rotating the active pipe adjusts the distance the inlet on the passive pipe extends beyond the outer casing, thus adjusting the water level inside the inner tank. When the water pressure is too high, rotating the active pipe lowers the inlet on the passive pipe, reducing the water level inside the inner tank. This allows for greater expansion space between the water and air, reducing the pressure inside the tank and effectively preventing frequent opening of the safety valve, thus improving the user experience.

[0015] In one embodiment, the active tube and the driven tube are provided with a transmission part and a transmission surface, respectively.

[0033] The water heater described in this utility model has the following advantages compared with the prior art:

[0034] It is understood that there is a space between the water level and the top of the inner tank, containing air. During heating, the water and air inside the inner tank expand, increasing the pressure inside. In the aforementioned water heater, the active and driven pipes within the outer casing work together. Rotating the active pipe adjusts the distance the inlet of the driven pipe extends beyond the outer casing, thus adjusting the water level inside the inner tank. When the water pressure is too high, rotating the active pipe lowers the inlet of the driven pipe, reducing the water level inside the inner tank.

[0070] Example 1

[0071] like Figures 1 to 4 As shown, and refer to Figure 5 This embodiment provides a water outlet assembly, including an outer sleeve 1, an active pipe 2, and a driven pipe 3. The outer sleeve 1 is fixed to the outlet of the inner liner 100. The active pipe 2 is disposed within the outer sleeve 1 and can rotate around the axis of the outer sleeve 1. The active pipe 2 has a liquid outlet. The driven pipe 3 is disposed within the outer sleeve 1 and can move along the axis of the outer sleeve 1. The driven pipe 3 has a liquid inlet 30, which connects to the liquid outlet through the inner cavity of the driven pipe 3 and the inner cavity of the active pipe 2. The active pipe 2 and the driven pipe 3 are connected in a transmission manner within the outer sleeve 1. During rotation, the active pipe 2 can drive the driven pipe 3 to adjust the distance the liquid inlet 30 extends beyond the outer sleeve 1. The active pipe 2 and / or the driven pipe 3 are sealed to the inner wall of the outer sleeve 1.

[0072] In this invention, it is understood that there is a space between the water level in the inner tank 100 and the top of the inner tank 100, and air is contained in this space. When heated, the water and air in the inner tank 100 expand, resulting in an increase in pressure inside the inner tank 100. When the above-mentioned water outlet assembly is used in a water heater, the active pipe 2 and the driven pipe 3 inside the outer sleeve 1 cooperate to adjust the distance of the liquid inlet 30 on the driven pipe 3 extending out of the outer sleeve 1 when the active pipe 2 rotates, thereby adjusting the liquid level in the inner tank 100. When the water pressure is too high, the liquid inlet 30 on the driven pipe 3 can be lowered by rotating the active pipe 2, thereby lowering the liquid level in the inner tank 100. This allows for greater expansion space for the water and air inside the inner tank 100, reducing the pressure inside the inner tank 100 and effectively preventing the frequent opening of the safety valve 94, thus improving the user experience.

[0073] In this embodiment, the active pipe 2 and the driven pipe 3 inside the outer sleeve 1 cooperate to adjust the distance of the liquid inlet 30 on the driven pipe 3 extending out of the outer sleeve 1 when the active pipe 2 rotates. Thus, when the water pressure is too high, pressure can be relieved by lowering the height of the liquid inlet 30, avoiding frequent opening of the safety valve 94. The pressure-relieved water flows out through the water outlet assembly, which is safer and more reliable, ensuring the life of the safety valve 94 and the safety of the water heater. Furthermore, the transmission parts of the active pipe 2 and the driven pipe 3 are inside the outer sleeve 1, avoiding exposure to the outside and the influence of water, making it safer and more reliable.

[0074] Specifically, the outlet is located at the end of the active pipe 2 opposite to the driven pipe 3, and the inlet 30 is located at the end of the driven pipe 3 opposite to the active pipe 2. This arrangement simplifies the structure of the active pipe 2 and the driven pipe 3, making the placement of the inlet 30 and the outlet simpler.

[0075] Specifically, the driving tube 2 and the driven tube 3 each have a transmission part and a transmission surface, respectively. The transmission surface is inclined relative to the axis of the outer tube 1. During the rotation of the driving tube 2, the transmission part abuts against different positions of the transmission surface to drive the driven tube 3 to move. The above configuration is simple in structure and easy to install, enabling the driving tube 2 to efficiently and conveniently abut against the driven tube 3.

[0076] More specifically, the top end of the active tube 2 is provided with an active surface 21, and the bottom end of the driven tube 3 is provided with a driven surface 31. Both the active surface 21 and the driven surface 31 are inclined relative to the axis of the outer tube 1, and the included angles with the axis of the outer tube 1 are equal. The top end of the active surface 21 is the transmission part, and the driven surface 31 is the transmission surface. When the active surface 21 and the driven tube 3 are in contact with each other, the distance that the liquid inlet 30 extends out of the outer tube 1 is the shortest. The arrangement of the active surface 21 and the driven surface 31 is simple in structure and easy to set up, enabling the active tube 2 to efficiently and conveniently abut against the driven tube 3.

[0077] In this embodiment, as Figure 1 As shown, and refer to Figure 3 and Figure 4 The outer sleeve 1, the active tube 2, and the driven tube 3 are coaxially and vertically arranged. The liquid outlet is located at the bottom end of the active tube 2, the active surface 21 is located at the top end of the active tube 2, the liquid inlet 30 is located at the top end of the driven tube 3, and the driven surface 31 is located at the bottom end of the driven tube 3. The orientations of the top and bottom are as follows: Figure 1 As indicated, the active surface 21 can be obtained by beveling at the end of the active tube 2, and the driven surface 31 can be obtained by beveling at the end of the driven tube 3. The active surface 21 and the driven surface 31 are easy to process and have low cost. The liquid inlet 30 at the top of the driven tube 3 is not lower than the opening at the top of the outer tube 1.

[0078] In another embodiment, the outlet may also be located on the side wall of the active tube 2.

[0079] In another embodiment, the inlet 30 may also be located on the side wall of the driven pipe 3.

[0080] In another embodiment, the top end of the active tube 2 is provided with an active surface 21, which serves as a transmission surface and is set at an angle to the axis of the outer tube 1. Correspondingly, a protrusion is provided on the driven tube 3 for the active surface 21 of the active tube 2. The protrusion serves as a transmission part and is supported by the active surface 21. When the protrusion abuts against the active surface 21 at different positions, the distance by which the liquid inlet 30 extends out of the outer tube 1 is different. The above arrangement simplifies the structure of the driven tube 3.

[0081] In another embodiment, the driven tube 3 has a driven surface 31 at its bottom end, which serves as a transmission surface and is set at an angle to the axis of the outer tube 1. Correspondingly, a protrusion is provided on the driving tube 2 for the driven surface 31 of the driven tube 3. This protrusion acts as a transmission part, and when it abuts against the driven surface 31 at different positions, the distance the inlet 30 extends beyond the outer tube 1 varies. This arrangement simplifies the structure of the driving tube 2.

[0082] In another embodiment, the active tube 2 is sleeved on the outside of the driven tube 3, the active surface 21 is disposed at the top end of the active tube 2, and the driven surface 31 or protrusion is disposed on the outer periphery of the driven tube 3.

[0083] In another embodiment, the active tube 2 passes through the driven tube 3, the driven surface 31 is disposed at the bottom end of the driven tube 3, and the active surface 21 or protrusion is disposed on the outer periphery of the active tube 2.

[0084] Specifically, such as Figure 1 As shown, and refer to Figure 3 and Figure 4The water outlet assembly also includes a reset elastic element 4. The outer sleeve 1 is provided with a fixed stop 11, and the driven tube 3 is provided with a movable stop 32. The fixed stop 11 is sealed to the outer wall of the driven tube 3, and / or the movable stop 32 is sealed to the inner wall of the outer sleeve 1. The reset elastic element 4 is sandwiched between the fixed stop 11 and the movable stop 32 and is configured to drive the driven tube 3 to press against the active tube 2. This configuration allows the active tube 2 to reliably and stably abut against the driven tube 3, enabling more precise and reliable adjustment of the distance between the inlet 30 and the outlet.

[0085] More specifically, the fixed stop 11 is annularly arranged on the inner wall of the outer sleeve 1, the movable stop 32 is annularly arranged on the outer wall of the driven tube 3, and the elastic element 4 is a spring, sleeved on the driven tube 3 and sandwiched between the fixed stop 11 and the movable stop 32. The above arrangement makes the spring element 4 more stable and reliable in its arrangement between the outer sleeve 1 and the driven tube 3.

[0086] In this embodiment, the fixed stop 11 is sealed and fitted to the outer wall of the driven tube 3, and the movable stop 32 is sealed and fitted to the inner wall of the outer tube 1. The fixed stop 11 is disposed at one end of the outer tube 1 corresponding to the driven tube 3 and is fitted to the outer wall of the driven tube 3. Both the fixed stop 11 and the movable stop 32 play a role in sealing the gap between the outer tube 1 and the driven tube 3.

[0087] Specifically, such as Figure 2 As shown, both the outer tube 1 and the driven tube 3 are provided with a guide groove 12 and a guide block 33, respectively. The guide block 33 is slidably disposed in the guide groove 12, limiting the movement of the driven tube 3 along the axis of the outer tube 1. The above configuration is simple in structure and reliable in limiting movement.

[0088] More specifically, such as Figure 1 As shown, one end of the outer sleeve 1 is provided with a mounting flange 13, and the outer side of the outer sleeve 1 is fitted with a mounting component 14, such as... Figure 4 As shown, a snap-fit ​​groove is provided on one side of the water outlet pipe seat 5. The mounting part 14 is snapped into the snap-fit ​​groove, and the mounting flange 13 is pressed against the bottom of the snap-fit ​​groove, thereby fixing the outer sleeve 1 to the water outlet pipe seat 5.

[0089] In this embodiment, the guide groove 12 is disposed on the inner wall of the outer sleeve 1 and extends along the axial direction of the outer sleeve 1. The guide block 33 is disposed on the outer wall of the driven pipe 3. The outer wall of the mounting flange 13 is provided with a first locking surface, which is parallel to the axis of the outer sleeve 1. When the mounting member 14 is engaged in the mounting groove, the first locking surface abuts against the inner wall of the mounting groove, thereby limiting the rotation of the outer sleeve 1 relative to the water outlet pipe seat 5. The outer wall of the mounting member 14 is provided with a second locking surface, which is parallel to the axis of the outer sleeve 1. When the mounting member 14 is engaged in the mounting groove, the second locking surface abuts against the inner wall of the mounting groove, thereby limiting the rotation of the mounting member 14 relative to the water outlet pipe seat 5.

[0090] Specifically, the water outlet assembly also includes a water outlet pipe seat 5 and a water outlet pipe connector 6. The water outlet pipe seat 5 has a channel, the outer sleeve 1 is fixedly connected to the water outlet pipe seat 5, and the interior of the outer sleeve 1 communicates with the channel. The water outlet pipe connector 6 is rotatably mounted on the water outlet pipe seat 5, and the active pipe 2 is fixedly connected to the water outlet pipe connector 6. The liquid outlet is connected to the outside through the water outlet pipe connector 6. This configuration simplifies the structure of the outer sleeve 1 and the active pipe 2, allowing the active pipe 2 to rotate stably and reliably relative to the outer sleeve 1.

[0091] More specifically, both the outlet pipe seat 5 and the outlet pipe connector 6 are equipped with a limiting groove 51 and a limiting block 61, respectively. The limiting block 61 extends into the limiting groove 51, and the limiting groove 51 and the limiting block 61 cooperate to limit the rotation angle of the active pipe 2 relative to the outer sleeve pipe 1. This arrangement avoids the situation where the distance between the inlet 30 and the outlet gradually decreases and then suddenly increases or gradually increases and then suddenly decreases after the active pipe 2 rotates too far relative to the outer sleeve pipe 1. It ensures that the distance between the inlet 30 and the outlet increases or decreases in one direction only, making it safer and more reliable.

[0092] In this embodiment, the limiting groove 51 is disposed on the inner wall of the water outlet pipe 5, and the limiting block 61 is disposed on the outer wall of the water outlet pipe connector 6.

[0093] Specifically, the water outlet assembly also includes a locking element 7. The outer wall of the water outlet pipe connector 6 is provided with a stop groove 62. The locking element 7 is connected to the water outlet pipe seat 5 and extends into the stop groove 62. The above configuration allows the water outlet pipe seat 5 and the water outlet pipe connector 6 to be easily assembled and disassembled while maintaining a rotatable connection.

[0094] More specifically, the locking member 7 includes a locking part 71, which is rod-shaped, inserted into the water outlet pipe seat 5, and extends into the stop groove 62 to achieve positioning support for the rotation of the water outlet pipe connector 6.

[0095] In this embodiment, the locking member 7 is a U-shaped snap ring, the two support arms are two locking parts 71, and the water outlet pipe seat 5 is provided with two insertion holes. When the two locking parts 71 are inserted into the two insertion holes one by one, they extend into both sides of the stop groove 62 of the water outlet pipe connector 6. One locking part 71 is bent after passing through the water outlet pipe seat 5, so as to prevent the locking member 7 from falling off the water outlet pipe seat 5.

[0096] Specifically, the outer wall of the end of the water outlet pipe connector 6 opposite to the main pipe 2 is provided with a threaded part 63. By providing the threaded part 63, it is easy to connect an external water pipe to the water outlet pipe connector 6.

[0097] More specifically, the outer wall of the water outlet pipe connector 6 is also provided with a hexagonal locking part 64. The locking part 64 facilitates the rotation operation of the tooling.

[0098] More specifically, the outer wall of the water outlet pipe connector 6 is provided with an annular mounting groove 65, and a sealing ring 66 is fitted on the mounting groove 65. The sealing ring 66 is sandwiched between the outer wall of the water outlet pipe connector 6 and the inner wall of the water outlet pipe seat 5, which can seal the gap between the water outlet pipe seat 5 and the water outlet pipe connector 6.

[0099] In this embodiment, along the axial direction of the water outlet pipe connector 6, the locking part 64 is located between the limiting block 61 and the threaded part 63, the stop groove 62 is located on the side of the limiting block 61 away from the locking part 64, and the mounting groove 65 is located on the side of the stop groove 62 away from the limiting block 61.

[0100] In this embodiment, the active pipe 2 of the water outlet assembly is rotated manually by the user (by manually operating the tool to tighten the locking part 64 on the water outlet pipe connector 6), or the water outlet assembly is provided with an electric drive mechanism that can drive the active pipe 2 to rotate.

[0101] like Figure 5 As shown, this embodiment provides a water heater, including the aforementioned water outlet component.

[0102] In this water heater, there is a space between the water level in the inner tank 100 and the top of the inner tank 100, containing air. During heating, the water and air in the inner tank 100 expand, increasing the pressure inside the inner tank 100. When the water heater is heating, the active pipe 2 and the driven pipe 3 inside the outer sleeve 1 work together so that the distance of the liquid inlet 30 on the driven pipe 3 extending out of the outer sleeve 1 can be adjusted when the active pipe 2 rotates. This allows adjustment of the liquid level in the inner tank 100. When the water pressure is too high, the liquid inlet 30 on the driven pipe 3 can be lowered by rotating the active pipe 2, thereby lowering the liquid level in the inner tank 100. This allows for greater expansion space for the water and air in the inner tank 100, reducing the pressure inside the inner tank 100 and effectively preventing the safety valve 94 from opening frequently, thus improving the user experience.

[0103] Specifically, the water heater also includes an inner tank 100, a water outlet pipe seat 5 of the water outlet assembly is screwed to the mounting position on the inner tank 100, and the liquid inlet 30 of the water outlet assembly is located in the inner tank 100, through which water in the inner tank 100 is discharged.

[0104] More specifically, the water heater also includes a water inlet component 9, which is fixedly installed in the inner tank 100. External water sources enter the inner tank 100 through the water inlet component 9, thereby enabling the water heater to safely receive water.

[0105] More specifically, such as Figure 5 As shown, the water inlet assembly 9 includes an inlet pipe seat 91, an inlet pipe connector 92, an inlet pipe 93, and a safety valve 94. The inlet pipe seat 91 is screwed onto a mounting position on the inner liner 100. The inlet pipe connector 92 is fixed to the inlet pipe seat 91, located on the outside of the inner liner 100, and is used to connect to an external water pipe. The inlet pipe 93 is fixed to the inlet pipe seat 91 and located inside the inner liner 100. The inlet pipe connector 92 connects to the inlet pipe 93. External water enters the inner liner 100 after passing through the inlet pipe connector 92 and the inlet pipe 93. The safety valve 94, installed on the inlet pipe connector 92, is a conventional pressure valve in the art. Its specific structure and working principle are existing technology in the field and will not be described in detail here. When the pressure in the inner liner 100 exceeds a limit value, the safety valve 94 opens to release pressure, and the water in the inner liner 100 flows back into the inlet pipe connector 92 and then drips to the outside through the safety valve 94.

[0106] In this embodiment, the side wall of the water inlet pipe 93 is provided with multiple openings. After the external water source enters the water inlet pipe 93, it flows into the inner liner 100 through the multiple openings.

[0107] Specifically, the water outlet assembly is equipped with an electric drive mechanism capable of driving the active pipe 2 to rotate. The water heater also includes a pressure detector 200 and a controller 300. The outer casing 1 is fixed relative to the inner tank 100, the inlet 30 is located within the inner tank 100, the pressure detector 200 is located within the inner tank 100 to detect the pressure value within the inner tank 100, and the controller 300 is signal-connected to the pressure detector 200 and the water outlet assembly. Based on the pressure value within the inner tank 100, the controller controls the water outlet assembly to release pressure, thereby preventing the safety valve 94 from opening frequently.

[0108] More specifically, the water heater also includes an electric heating element 400, which is fixed to the inner tank 100 and used to heat the water stored in the inner tank 100.

[0109] More specifically, when the pressure value detected by the pressure detector 200 is greater than a first preset pressure value, the controller 300 controls the water outlet component to drive the active pipe 2, causing the inlet 30 to lower; optionally, the inlet 30 is lowered to a safe height, which can be preset. When the pressure value detected by the pressure detector 200 is less than a second preset pressure value, the controller 300 controls the water outlet component to drive the active pipe 2, causing the inlet 30 to rise; optionally, the inlet 30 is raised to a set height, which can be preset, where the second preset pressure value is less than the first preset pressure value. This configuration avoids manual operation, allowing the water heater to release pressure more promptly and efficiently through the water outlet component, and also efficiently controls the water outlet component to return to a high water level when the pressure in the inner tank 100 is too low.

[0110] In this embodiment, the first preset pressure value is 0.5 MPa, the second preset pressure value is 0.15 MPa, the pressure detector 200 and the controller 300 are conventional components in the art, and their specific structures and cooperative control principles are conventional settings in the art, which will not be described in detail here. The safe height and the set height of the liquid inlet 30 can be the same or different. The safe height of the liquid inlet 30 can be its minimum height, or an intermediate value between its minimum and maximum height, or an intermediate value of multiple gradient settings. The set height of the liquid inlet 30 can be its maximum height, or an intermediate value between its maximum and minimum height, or an intermediate value of multiple gradient settings.

[0111] In other embodiments, the first preset pressure value and the second preset pressure value may be other set values, which may be preset as needed.

[0112] In specific operations, it can be that during a single test, when the pressure value detected by the pressure detector 200 is greater than 0.5 MPa, the controller 300 directly controls the inlet 30 of the water outlet component to decrease to the minimum value and then stops the operation. Then, during the next test, when the pressure value detected by the pressure detector 200 is less than 0.15 MPa, the controller 300 directly controls the inlet 30 of the water outlet component to increase to the maximum value and then stops the operation. Alternatively, during a single test, when the pressure value detected by the pressure detector 200 is greater than 0.5 MPa, the controller 300 controls the inlet 30 of the water outlet component to gradually decrease according to a set gradient difference until the pressure value detected by the pressure detector 200 is no greater than 0.5 MPa. Simultaneously, when the pressure value detected by the pressure detector 200 is less than 0.15 MPa, the controller 300 controls the inlet 30 of the water outlet component to gradually increase according to a set gradient difference until the pressure value detected by the pressure detector 200 is no less than 0.15 MPa.

[0113] Example 2

[0114] like Figures 6 to 8 As shown, this embodiment provides a water outlet component and a water heater, with the same or corresponding components as in Embodiment 1 using the same or corresponding reference numerals. For simplicity, only the differences between this embodiment and Embodiment 1 are described below.

[0115] The difference between the water outlet component in this embodiment and that in Embodiment 1 is as follows:

[0116] Specifically, the water outlet assembly also includes a drive mechanism 8, which is configured to drive the active pipe 2 to rotate relative to the outer casing 1. This configuration makes the rotation of the active pipe 2 more convenient and efficient.

[0117] More specifically, the drive mechanism 8 includes a driver 81, a drive gear 82, and a driven gear 83. The drive gear 82 is located at the output end of the driver 81, and the driven gear 83 is located in the drive tube 2 and meshes with the drive gear 82. Based on the driver 81, transmission is achieved through the meshing drive gear 82 and driven gear 83, making the drive of the drive tube 2 more precise and efficient.

[0118] In this embodiment, the driver 81 is a servo motor, which is fixedly mounted on the water outlet pipe seat 5. The driving gear 82 is fixedly mounted on the output shaft of the servo motor. The driven gear 83 is fitted onto the water outlet pipe connector 6 and is located between the stop groove 61 and the locking part 64. The diameter of the driving gear 82 is smaller than that of the driven gear 83.

[0119] In other embodiments, the actuator 81 may also be a rotary cylinder.

[0120] In other embodiments, the drive mechanism 8 may also include a driver 81, a drive wheel, a driven wheel, and a transmission belt. The driver 81 is a servo motor or a rotary cylinder. The drive wheel is located at the output end of the driver 81, the driven wheel is located on the drive tube 2, and the transmission belt is wound around the drive wheel and the driven wheel. The drive wheel and the driven wheel are tensioned to realize the drive wheel and the driven wheel transmission through the transmission belt.

[0121] Specifically, the locking component 7 includes a locking part 71 and a clamping part 72 connected to each other. The locking part 71 is rod-shaped, inserted into the water outlet pipe seat 5, and extends into the stop groove 62 to achieve positioning support for the rotation of the water outlet pipe connector 6. The clamping part 72 is clamped on the outside of the driver 81 to fix the driver 81 to the water outlet pipe seat 5.

[0122] In this embodiment, as Figure 6As shown, the locking element 7 is a U-shaped snap ring, and a locking part 72 is provided at each end of the arc-shaped clamping part 72. The water outlet pipe seat 5 is provided with two insertion holes. The clamping part 72 clamps the driver 81. When the two locking parts 71 are inserted into the two insertion holes one by one, they extend into the two sides of the stop groove 62 of the water outlet pipe connector 6. One locking part 71 is bent after passing through the water outlet pipe seat 5, so as to prevent the locking element 7 from falling off the water outlet pipe seat 5.

[0123] Specifically, in the water heater, the controller 300 is connected to the pressure detector 200 and the driver 81 of the drive mechanism 8, thereby achieving precise control of the water outlet component.

[0124] More specifically, when the pressure value detected by the pressure detector 200 is greater than the first preset pressure value, the controller 300 controls the drive mechanism 8 to drive the active tube 2 to move, so that the liquid inlet 30 is lowered to a safe height; when the pressure value detected by the pressure detector 200 is less than the second preset pressure value, the controller 300 controls the drive mechanism 8 to drive the active tube 2 to move, so that the liquid inlet 30 is raised to a set height, and the second preset pressure value is less than the first preset pressure value.

[0125] Example 3

[0126] like Figures 9 to 13 As shown, this embodiment provides a water outlet component and a water heater, with the same or corresponding components as in Embodiment 1 using the same or corresponding reference numerals. For simplicity, only the differences between this embodiment and Embodiment 1 are described below.

[0127] The difference between the water outlet component in this embodiment and that in Embodiment 1 is as follows:

[0128] Specifically, the driving tube 2 is screwed to the driven tube 3. This arrangement improves the sealing effect between the driving tube 2 and the driven tube 3, and allows the driving tube 2 to drive the driven tube 3 more smoothly and reliably when rotating.

[0129] More specifically, such as Figure 9 and Figure 10 As shown, the outer wall of the active tube 2 is provided with external threads, and the inner wall of the driven tube 3 is provided with internal threads. The active tube 2 is screwed to the inner side of the driven tube 3. The above arrangement causes the gap between the active tube 2 and the driven tube 3 to extend downward, further improving the sealing effect between the active tube 2 and the driven tube 3.

[0130] In this embodiment, there is no need for rotational limiting between the water outlet pipe seat 5 and the water outlet pipe connector 6. Therefore, no limiting groove 51 is provided on the water outlet pipe seat 5, and no limiting block 61 is provided on the water outlet pipe connector 6.

[0131] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0132] It is understood that the above embodiments can be selectively combined as needed, provided that the combination of these technical features does not contradict each other. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. These embodiments not explicitly written should also be considered to be within the scope of this specification.

[0133] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
