Detailed Implementation

[0048] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0049] The present invention relates to a drainage device, comprising a control component 100, a moving component 200, a water-passing component 300, and a temperature-sensing element 400.

[0050] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the control component 100, movable component 200, and water-passing component 300 are distributed from top to bottom in the illustrated direction. The movable component 200 has a water-passing cavity 201, and its opening faces downwards towards the water-passing component 300. The control component 100 can move the movable component 200 from a first position to a second position, which are laterally distributed left and right in the illustration. When the control component 100 resets, it does not move the movable component 200 back from the second position to the first position. The water-passing component 300 and the movable component 200 are slidably connected. In this application, the sliding connection can be between two feature surfaces that abut against each other and slide relative to each other, or it can be a sliding connection through grooves or other mechanical structures. The water-passing component 300 includes a first channel 310 and a second channel 320. A temperature-sensing element 400 is installed between the water-passing cavity 201 and the water-passing component 300. When the movable component 200 is in the first and second positions, the first channel 310 and the second channel 320 have different operating states. Figure 3 As shown, under normal conditions, the active component 200 is located in the first position, at which time the first channel 310 and the second channel 320 are disconnected. Figure 4 As shown, when the control component 100 moves the movable component 200 to the second position, the water passage chamber 201 moves with the movable component 200. Both the first channel 310 and the second channel 320 are connected to the water passage chamber 201, thus making the first channel 310 and the second channel 320 interconnected. After the first channel 310 and the second channel 320 are connected, the temperature sensing element 400 is located on the path connecting the first channel 310 and the second channel 320. Liquid (such as water) flows between the first channel 310 and the second channel 320. The temperature sensing element 400 has a preset temperature. When the temperature sensing element 400 gradually rises from a low temperature to the preset temperature due to the influence of external temperature, such as water temperature, the temperature sensing element 400 will activate, causing the movable component 200 to move relative to the water passage component 300, causing the movable component 200 to reset from the second position to the first position, thereby switching the first channel 310 and the second channel 320 from the connected state to the disconnected state. The drainage device automatically resets according to the liquid temperature, meeting the requirement that water heaters and other equipment need to drain the initial cold water before use. Once the active component 200 returns to its first position, it will not automatically activate the cold water drainage function due to a drop in water temperature, effectively preventing water waste. The overall structure is simple, easy to use, and convenient to maintain. The drainage device can be used as a standard module with various types of push-button shower faucets, making it widely applicable. Shower faucets equipped with this drainage device can drain cold water from the hot water pipe separately, eliminating the need to drain cold water from the cold water pipe, thus saving more water than other pre-drained cold water faucets.

[0051] A second aspect of the present invention, such as Figure 12As shown, a drainage device 001 is applied in a water supply system having a hot water path 900. The hot water path 900 is connected to the first channel 310. The water supply system can be a water heater, etc. During use, the hot water in the hot water path 900 mixes with cold water from the outside before use. After one use, some water remains in the hot water path 900. Before the next use, this water gradually cools and becomes cold water. Before turning on the water supply system again to obtain hot water, the drainage device can be used to drain the remaining cold water from the hot water path 900. Specifically, the control component 100 is manually operated to move the movable component 200 from the first position to the second position. Water in the hot water path is discharged along the first channel 310, the water passage 201, and the second channel 320. After the cold water in the hot water pipe is completely drained, the hot water continues to flow. When the hot water flows through the temperature sensing element 400, the water temperature reaches the preset temperature of the temperature sensing element 400. The temperature sensing element 400 then drives the movable component 200 to reset to the first position, disconnecting the first channel 310 and the second channel 320. The hot water pipe can no longer drain water through the drainage device. The water supply equipment then supplies water through its own channels. After the temperature sensing element 400 resets, it will not automatically move the movable component 200 to the second position due to a drop in water temperature. The drainage device allows for the separate discharge of residual cold water from the beginning of the hot water pipe, solving the problem of water waste caused by the mixing of residual cold water with normal cold water in traditional water heaters and other equipment, thus effectively saving water.

[0052] In some embodiments, such as Figure 3 As shown, the operation of the control component 100 is a pressing reciprocating translation, with the pressing action of the control component 100 along a first direction. The movement action of the movable component 200 is a translation along a second direction. The first and second directions intersect. Preferably, in the directions shown in the figure, the first direction is the vertical direction (up and down), and the second direction is the horizontal direction (left and right), with the first and second directions perpendicular to each other.

[0053] In some specific embodiments, such as Figure 1 , Figure 3 and Figure 6As shown, the control component 100 includes a pressing member 110 and a lever 120. The pressing member 110 may be, but is not limited to, a rod structure. The rod is installed vertically. The lever 120 may be, but is not limited to, a rod structure with a bend. One end of the lever 120 serves as a hinged end 121, which is hinged to the pressing member 110 via a pivot. In this embodiment, the lever 120 swings left and right relative to the pressing member 110 about the pivot. The other end of the lever 120 is a free end 122. The free end 122 slides on the movable component 200. The pressing member 110 moves in a first direction, and the pressing member 110 moves to a third position and a fourth position. The pressing member 110 presses down from the third position to the fourth position. During the pressing process, the lever 120 swings to the right relative to the pressing member 110, and its free end 122 slides against the movable component 200. When the lever 120 swings to the right, its free end 122 abuts against the right side wall of the movable component 200, thereby pushing the movable component 200 to translate to the right, causing the movable component 200 to translate from the first position to the second position. The linear movement of the pressing member 110 in the first direction is converted into the linear movement of the movable component 200 in the second direction by the swinging action of the lever 120.

[0054] Furthermore, such as Figure 1 , Figure 3 and Figure 7 As shown, the movable component 200 is provided with a slide groove 210. The slide groove 210 extends left and right in a second direction. The slide groove 210 has a first end 211 and a second end 212 in the second direction, which are distributed left and right. The free end 122 abuts against the bottom surface of the slide groove 210 and slides relative to the first end 211 and the second end 212. When the pressing member 110 is pressed down, the free end 122 slides on the bottom surface of the slide groove 210 until the free end 122 abuts against the second end 212, and pushes the movable component 200 to the right to the second position through the second end 212. When the pressing member 110 returns to the third position from the fourth position, the free end 122 slides in the slide groove 210. At this time, the free end 122 does not exert a pushing force on the slide groove 210 in the second direction, thereby keeping the movable component 200 in the second position.

[0055] Among them, such as Figure 1 and Figure 3 As shown, the control component 100 includes a first elastic element 130. The first elastic element 130 can be a first spring. After the control component 100 moves the movable component 200 to the second position, the first elastic element 130 exerts a first elastic force on the control component 100. This first elastic force can drive the control component 100 to reset, allowing the movable component 200 to remain in the second position. Figure 3As shown, in this embodiment, one end of the first elastic member 130 abuts against the pressing member 110, and the other end abuts against a fixed component within the drainage device. Figure 4 As shown, when the pressing member 110 is pressed down, the first elastic member 130 is elastically compressed. (As indicated...) Figure 5 As shown, after the active component 200 reaches the second position, the pressing member 110 is released. Under the first elastic force of the first elastic member 130, the pressing member 110 automatically resets upward. After the user presses the control component 100, the first elastic member 130 automatically resets the control component 100, which, together with the temperature sensing element 400, realizes the automatic reset action of the entire drainage device.

[0056] In some embodiments, such as Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the movable component 200 includes an adapter 220 and a movable seat 230. The adapter 220 is fixedly mounted on the movable seat 230, and the adapter 220 and the movable seat 230 move synchronously. A water passage cavity 201 is formed on the end face of the movable seat 230 facing the water passage component 300. In this embodiment, the water passage component 300 is located below the movable seat 230, and the water passage cavity 201 is formed on the bottom surface of the movable seat 230. A sliding groove 210 is formed on the adapter 220, and one end (free end 122) of the control component 100 slides in the sliding groove 210 on the adapter 220. Depending on the model, adapters 220 and movable seats 230 of different sizes can be used together, suitable for movable components 200 with different first and second positions or different sizes of water passage cavities 201. The adapter 220 can also be integrally formed on the movable seat 230 as a single component. Figure 1 and Figure 3As shown, it also includes a bracket 500. The bracket 500 is fixed in position relative to the drainage device, which may have a housing 600, and the bracket 500 is fixed to the housing 600. The bracket 500 is located above the adapter 220. One end of the first elastic member 130 abuts against the pressing member 110, and the other end abuts against the bracket 500, supporting the first elastic member 130. A second elastic member 510 is provided between the bracket 500 and the adapter 220, and the second elastic member 510 may be a second spring 511. The second elastic member 510 exerts a second elastic force on the adapter 220. The second elastic force causes the end face of the water passage cavity 201 on the movable component 200 to press against the water passage component 300. In this embodiment, the water passage cavity 201 is disposed on the bottom surface of the movable component 200, and the bottom surface of the movable component 200 is in close contact with the water passage component 300. The second elastic force presses the movable component 200 downward, increasing the pressure between the movable component 200 and the water passage component 300, thereby increasing the friction between the two, so that the movable component 200 remains in the second position before the temperature sensing element 400 is reset.

[0057] In some specific instances, such as Figure 1 and Figure 7 As shown, a column 221 is provided on the adapter 220. The column 221 is hollow and open at the top. A second elastic element 510 is installed in the column 221. The second elastic element 510 includes a second spring 511 and a top column 512. The two ends of the second spring 511 abut against the top column 512 and the column 221, respectively. The upper end of the top column 512 faces the bracket 500, and the upper end of the top column 512 is set as a spherical end 513. The spherical end 513 abuts against the bottom surface of the bracket 500. When the movable component 200 translates, the spherical end 513 slides relative to the bottom surface of the bracket 500, reducing the friction between the movable component 200 and the bracket 500, while ensuring that the bracket 500 exerts downward pressure on the movable component 200.

[0058] In some embodiments, such as Figure 3 , Figure 8 , Figure 9 and Figure 10As shown, the lower end face of the movable component 200 is the first connecting surface 202, and the upper end face of the water-passing component 300 is the second connecting surface 301. The first connecting surface 202 and the second connecting surface 301 are slidably connected to each other. The water-passing cavity 201 is formed on the first connecting surface 202, and one end of the first channel 310 and one end of the second channel 320 are formed on the second connecting surface 301. By moving the first connecting surface 202 and the second connecting surface 301 relative to each other, the relative positions of the water-passing cavity 201 and the first channel 310 and the second channel 320 are changed. Specifically, when the movable component 200 is in the first position, the water-passing cavity 201 communicates with the end of one of the first channel 310 and the second channel 320, while the other is not communicated with the water-passing cavity 201, thus making the first channel 310 and the second channel 320 not communicate with each other. Alternatively, in the first position, the water-passing cavity 201 is not communicated with the ends of either the first channel 310 or the second channel 320. When the active component 200 is in the second position, the water passage 201 is connected to the end of the first channel 310 and the end of the second channel 320, and the first channel 310 and the second channel 320 are connected through the water passage 201.

[0059] The temperature sensing element 400 can be a component that changes shape according to temperature changes, or it can be an electronic component that operates according to temperature changes. In some embodiments, such as Figure 1 , Figure 3 , Figure 8 and Figure 9 As shown, a recess 330 is formed on the second connecting surface 301. The temperature sensing element 400 is a memory spring. The memory spring is sleeved on a retaining element 410. One end of the retaining element 410 is fixed to either the water passage cavity 201 or the recess 330, and the memory spring acts on the other. In this embodiment, the retaining element 410 can be L-shaped. The upper end of the retaining element 410 is inserted and fixed in the water passage cavity 201, one end of the memory spring abuts against the retaining element 410, and the other end abuts against the recess 330. When the movable component 200 moves from the first position to the second position, it drives the retaining element 410 to move, and the retaining element 410 compresses the memory spring. When the temperature of the liquid flowing through the memory spring reaches the phase change temperature of the memory spring, the memory spring extends and resets, and the retaining element 410 drives the movable component 200 to reset from the second position to the first position.

[0060] In some embodiments, such as Figure 1 , Figure 2 , Figure 9 and Figure 10As shown, the drainage device also includes a housing 600. The control component 100, the movable component 200, and the water-passing component 300 are all mounted on the housing 600. In this embodiment, the housing 600 is cylindrical. The control component 100 is vertically slidably mounted on the upper part of the housing 600. The movable component 200 is mounted below the control component 100 and located inside the housing 600. The water-passing component 300 is fixed to the lower part of the housing 600. The water-passing component 300 can be a separate component or a component formed by a mounting base 340, a sealing ring 350, and a water-passing plate 360, etc. The first channel 310 and the second channel 320 can be respectively opened on the water-passing component 300 along a first direction.

[0061] like Figure 1 , Figure 2 and Figure 11 As shown, an adjusting seat 700 is movably mounted on the housing 600. The adjusting seat 700 can push the movable component 200 from the second position to the first position. When the user accidentally operates the control component 100 when drainage is not required, the user can operate the adjusting seat 700 to quickly reset the movable component 200 from the second position to the first position to stop drainage, thus manually resetting the movable component 200. Specifically, the housing 600 is provided with an annular groove 610. An adjusting piece 710 extends downward from the side edge of the adjusting seat 700. The adjusting piece 710 is arc-shaped, and its arc shape matches the shape of the annular groove 610. The adjusting piece 710 passes downward through the annular groove 610. The adjusting seat 700 rotates relative to the housing 600 along the annular groove 610. Figure 11 As shown, the left and right transverse sections of the adjusting plate 710 gradually thicken along the arc-shaped extension direction. The adjusting plate 710 extends into the housing 600 through the annular groove 610 and surrounds the side of the movable component 200. When the movable component 200 moves to the second position, the adjusting plate 710 rotates relative to the housing 600 with the adjusting seat 700. The thicker part of the adjusting plate 710 can abut against the movable component 200. With rotation, the adjusting plate 710 pushes the movable component 200 back to the first position. After the movable component 200 is reset, the user manually reverses the adjusting seat 700 to reset it, thus completing the manual reset operation of the movable component 200.

[0062] In some specific embodiments, such as Figure 1 , Figure 3 and Figure 11As shown, a third elastic element 810 and a positioning post 820 are provided between the adjusting seat 700 and the housing 600. The third elastic element 810 connects the positioning post 820 and the housing 600. The third elastic element 810 can be a third spring. The third elastic element 810 exerts a third elastic force on the positioning post 820, causing the positioning post 820 to push towards the adjusting seat 700. The adjusting seat 700 has a positioning hole 720 on its end face facing the housing 600, and one end of the positioning post 820 can move inside or outside the positioning hole 720. The third elastic element 810 and the positioning post 820 are mounted on the housing 600. Under normal conditions, the upper end of the positioning post 820 abuts against the bottom surface of the adjusting seat 700 and slides into the positioning hole 720. When it is necessary to manually reset the movable component 200 using the adjusting seat 700, the adjusting seat 700 is rotated, and the upper end of the positioning post 820 slides out of the positioning hole 720. After the movable component 200 returns to the first position, the adjusting seat 700 reverses until the positioning hole 720 and the positioning pin 820 are re-aligned and the positioning pin 820 slides back into the positioning hole 720, thus completing the reset of the adjusting seat 700. When one end of the positioning pin 820 slides into the positioning hole 720, under the third elastic action of the third elastic element 810, the positioning pin 820 and the positioning hole 720 touch and trigger a "tick" sound, indicating that the adjusting seat 700 has been reset.
