Technical Field
[0001] The utility model relates to the field of toilet drain valves, and in particular to a drain valve with controllable drain speed and a flushing system. Background Art
[0002] Some existing drain valves use full-drain and half-drain floats to identify water levels to control the closing time of the drain valve outlet, thereby achieving the full-drain and half-drain functions of the drain valve; some drain valves cancel the full-drain and half-drain floats and directly control the length of time the outlet is open to achieve the full-drain and half-drain functions of the drain valve. Among them, the half-drain function of the drain valve has a small drainage volume (such as 3.0L, 3.5L), resulting in a short drainage time and a short siphon time for the main flush of the toilet, resulting in poor function. Extending the siphon time of the half-drain can improve the flushing effect of the toilet.

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0032] It should be noted that in the present invention, the terms "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element of the present invention must have a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example
[0033] Cooperate Figures 1 to 6 As shown, the utility model discloses a drain valve and flushing system with controllable drainage speed. The drain valve effectively prolongs the flushing time of half the drainage by controlling the drainage speed of half the drainage, that is, prolongs the siphon time of half the drainage, and effectively enhances the flushing effect of half the drainage.
[0034] Cooperate Figures 1 to 6As shown, a drain valve with controllable drainage speed comprises:
[0035] A base 10, wherein the base 10 is provided with a drain port 11, a first drain port 12, and a second drain port 13;
[0036] The sealing assembly 20 is movably arranged on the base 10. When the sealing assembly 20 is in the sealing position, the sealing assembly 20 seals the drain port 11, and the drain valve does not drain water. When the sealing assembly 20 moves to the first position, the first drain port 12 is connected to the drain port 11, and the drain valve is in the first drainage mode. When the sealing assembly 20 moves to the second position, the first drain port 12 and the second drain port 13 are both connected to the drain port 11, and the drain valve is in the second drainage mode.
[0037] The driving mechanism 30 drives the sealing assembly 20 to switch between the sealing position, the first position, and the second position.
[0038] The drain valve described in this embodiment is a drain valve installed in a water tank in a toilet flushing system. Its drainage principle is basically the same as that of the existing drain valve. In the initial position, the sealing component 20 closes the drain port 11 of the base 10, and the drain valve does not drain water at this time. The sealing component 20 moves to open the drain port 11, and the first drain port 12 or the first drain port 12 and the second drain port 13 are connected to the drain port 11 at the same time. The water stored in the water tank enters the drain port 11 through the first drain port 12 or the first drain port 12 and the second drain port 13 and is discharged, thereby realizing the drainage function of the drain valve.
[0039] The base 10 is provided with two groups of drain ports (a first drain port 12 and a second drain port 13). When the driving mechanism 30 drives the sealing assembly 20 to the first position, only the first drain port 12 is connected to the drain port 11 for drainage, and the drain valve is in the first drainage mode; when the driving mechanism 30 drives the sealing assembly 20 to the second position, both the first drain port 12 and the second drain port 13 are connected to the drain port 11 for drainage, and the drain valve is in the second drainage mode. The first drainage mode of the drain valve is the half-drain mode of the drain valve, and the first drainage mode of the drain valve is the full-drain mode of the drain valve. Compared with the existing design of the drain valve with the same drainage flow rate for the full and half-drain (only one drain port), the utility model has a different design of opening the drain port in the full and half-drain mode, so that the drainage flow rate of the drain valve in the half-drain mode is significantly reduced, thereby effectively extending its siphon time. For the full-drain mode, the drainage flow rate is guaranteed to be large enough, so that the flushing effect of the half-drain and full-drain can be effectively guaranteed. It should be noted here that when the drain valve is in half-drain mode, it mainly flushes out some colored liquids, and the length of siphon time is the main factor affecting its flushing effect. When the drain valve is in full-drain mode, some solid matter needs to be flushed out, and the drainage flow rate is the main factor affecting its flushing effect.
[0040] Cooperate Figures 1 to 3 As shown, in this embodiment, the specific design of the base 10 is as follows: the base 10 is a cylinder, the bottom of the cylinder is provided with the drain port 11, the side wall of the cylinder is provided with the first drain port 12 and the second drain port 13 from bottom to top, the first drain port 12 and / or the second drain port 13 are connected with the drain port 11 to form a drainage channel, when the sealing component 20 is in the sealing position, the sealing component 20 is sealed with the drain port 11, when the sealing component 20 is in the first position, the sealing component 20 is located between the first drain port 12 and the second drain port 13, when the sealing component 20 is in the second position, the sealing component 20 is located above the second drain port 13. Among them, the sealing component 20 is a water-stopping rubber pad, which can be sealed with the drain port 11. The sealing component adopts the existing design, which is adapted to seal with the drain outlet when in the sealing position, and cooperates with the inner wall of the base 10 when in the first position. At this time, the sealing component 20 and the base 10 can be sealed, so that the second drain outlet 13 and the drain outlet 11 are not connected; or the sealing component 20 and the base 10 are gap-fitted, and the water outflow of the gap is smaller than the water outflow of the second drain outlet 13.
[0041] There are multiple first drain ports 12 and multiple second drain ports 13, and the first drain ports 12 and the second drain ports 13 are sequentially arranged along the circumferential side wall of the base 10. Multiple first drain ports 12 are sequentially designed along the side wall of the base 10, and multiple second drain ports 13 are sequentially designed along the side wall of the base 10, so as to ensure that the water in the water tank can quickly enter the drain port 11.
[0042] The driving mechanism 30 can be driven and controlled by the cooperation of a purely mechanical structure, or by an electric control method. When the driving mechanism 30 is a mechanical device, the sealing component 20 is driven to switch between the sealing position, the first position, and the second position by the cooperation of the mechanical structure, for example, the sealing component 20 is driven to move by the cooperation of a button, a float, a connecting rod mechanism, etc. This part can adopt the existing design and will not be elaborated here; the driving mechanism 30 is an electric control device, which drives the sealing component 20 to switch between the sealing position, the first position, and the second position by electric control technology, for example, the sealing component 20 is driven to move by a motor, a wire rope, etc. ( Figure 1 , Figures 4 to 6 The driving mechanism 30 shown is an electronic control device, which controls the opening time of the sealing assembly 20 to achieve different water discharge amounts. The electronic control device here can adopt the existing design and will not be elaborated here.
[0043] The opening area of the first water outlet 12 and / or the second water outlet 13 can be adjusted. In this embodiment, the first water outlet 12 and the second water outlet 13 are partially or completely connected to the drain port 11 by the cooperation of the sealing component 20 and the side wall at different positions of the base 10, so that the opening area of the first water outlet 12 and the second water outlet 13 can be adjusted. In this design, it is more appropriate to drive the driving mechanism 30 with electric control technology, and the electric control technology can flexibly realize the displacement of the sealing component 20 on the base 10, so as to realize the flexible adjustment of the opening area of the first water outlet 12 and the second water outlet 13.
[0044] The base 10 is also provided with a third drain port, which is located above the second drain port 13. When the sealing assembly 20 moves to the third position, the first drain port 12, the second drain port 13 and the third drain port are all connected to the drain port 11, and the drain valve is in the third drain mode. The third drain port (not shown in the figure) is also provided on the side wall of the base 10, located above the second drain port 13. When the sealing assembly 20 rises to the top of the third drain port, the first drain port 12, the second drain port 13 and the third drain port are all connected to the drain port 11. At this time, the drainage flow rate of the drain valve reaches the maximum value, and the drain valve is in the third drainage mode. The third drainage mode can be understood as another full drainage mode. Both of them will drain all the water in the water tank, but compared with the full drainage mode (the sealing assembly 20 is in the second position), the drainage flow rate of the third drainage mode is greater. Consumers choose to use this drainage mode according to actual needs. Usually, the first drainage mode and the second drainage mode can meet daily use.
[0045] The utility model also discloses a flushing system, including the water tank, the water inlet valve and the above-mentioned drain valve, the water inlet valve is installed on the water tank, the water tank is provided with a mounting hole connected to the drain pipe, the base 10 is installed on the mounting hole, and the drain port 11 is connected to the mounting hole and the drain pipe. The drain pipe is connected to the toilet flushing port, the bottom end of the base 10 is adapted to be installed in the mounting hole at the bottom of the water tank, and the drain port 11 is connected to the mounting hole. When the drain port 11 is opened, the water in the water tank enters the drain port 11 through the first drain port 12 or the first drain port 12 and the second drain port 13, and finally flushes the toilet bowl through the drain pipe.
[0046] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
