Abstract
Description
Technical Field
[0001] This invention relates to the field of energy conservation and environmental protection, and in particular to an energy-saving and environmentally friendly toilet device. Background Technology
[0002] The urinals are designed based on men's toilet habits. After use, they can be automatically flushed by an infrared sensor system that detects when a person leaves.
[0003] Existing urinals generally use the same drainage structure as toilets, namely a connecting pipe combined with a siphon pipe. After excretion, regardless of the amount of waste, the urinal is flushed with a fixed amount of water. In addition, in order to realize the function of the siphon pipe, there are also certain requirements for the amount of water used for each flush. These two issues lead to water waste.
[0004] Some patent applications propose adding water pressure sensors or gravity sensors to urinals to sense the amount of excretion and release corresponding flushing water. However, during the excretion process, the liquid levels at both ends of the connecting pipe remain basically the same (urine enters at one end, and an equal amount of water is discharged at the other end). The water pressure and gravity in the connecting pipe remain basically unchanged, so sensing the water pressure and gravity cannot effectively monitor the amount of excretion.
[0005] In view of this, how to provide an energy-saving and environmentally friendly toilet that can solve all or part of the above-mentioned technical problems is a technical problem that urgently needs to be solved by those in the field. Summary of the Invention
[0006] The purpose of this invention is to provide an energy-saving and environmentally friendly toilet device to solve the problems existing in the prior art. It can achieve the effects of speeding up the start-up speed of the siphon tube, reducing the minimum water volume for a single flush, and adaptively adjusting the flushing water volume according to the amount of excretion.
[0007] To achieve the above objectives, the present invention provides the following solution: The present invention provides an energy-saving and environmentally friendly toilet device, comprising:
[0008] A urinal, wherein the bottom of the urinal has a drain outlet;
[0009] A connecting pipe, one end of which is connected to the discharge port and the other end of which is connected to the siphon pipe;
[0010] An extension tube is provided, which is vertically arranged, closed at the top and connected to the connecting tube at the bottom. The connection between the extension tube and the connecting tube is close to the connection between the connecting tube and the siphon tube.
[0011] Rotate the valve, which is rotatably connected to the connecting pipe or siphon between a first position and a second position. When the valve is in the first position, it closes the connection between the connecting pipe and the siphon and connects the connecting pipe to the extension pipe. When the valve is in the second position, the connecting pipe connects to the siphon and the extension pipe connects to the siphon.
[0012] Furthermore, the rotary valve includes: an inner disc, a sealing rubber ring provided on the outer edge of the inner disc, a mounting hole provided radially through the inner disc and the sealing rubber ring, a rotating shaft rotatably disposed in the mounting hole, the left and right ends of the rotating shaft being fixedly connected to the inner wall of the connecting pipe or the inner wall of the siphon pipe respectively, and the inner disc and the sealing rubber ring being able to rotate along the rotating shaft.
[0013] Furthermore, the sealing rubber ring is shaped to fit the connection between the connecting pipe and the siphon pipe.
[0014] Furthermore, it also includes:
[0015] A telescopic motor is hinged to a first hinge seat via a first hinge rod. The first hinge seat is fixedly disposed on the inner side wall of the extension tube. The output end of the telescopic motor is hinged to a second hinge seat via a second hinge rod. The second hinge seat is fixedly disposed on the inner disc. The telescopic motor can drive the inner disc to rotate between a first position and a second position.
[0016] Furthermore, the second hinge seat is located above the center of the inner disk. When the inner disk moves from the first position to the second position, the top of the inner disk rotates toward the siphon tube.
[0017] Furthermore, multiple liquid level sensors are installed inside the extension pipe from bottom to top. These multiple liquid level sensors are communicatively connected to the controller. After the liquid level sensors at different heights come into contact with the liquid surface inside the connecting pipe, they send different electrical signals to the controller. A water outlet mechanism is installed inside the urinal. The controller receives different electrical signals and controls the water outlet mechanism to output different water volumes.
[0018] The present invention discloses the following technical effects:
[0019] 1. An extension pipe was added to the original structure. The top of the extension pipe is closed, and the bottom end connects to the connecting pipe, forming a "semi-communicating vessel" structure with one end closed and the other open. When the urinal is in use, excrement flows into the urinal, increasing the liquid level at the outlet. The liquid level in the extension pipe also increases. However, because the upper end of the extension pipe is closed, the air pressure inside the extension pipe increases, resulting in the liquid level in the urinal being higher than that in the extension pipe. After opening the rotary valve, because the liquid level in the urinal is much higher than the connection between the siphon and the connecting pipe, the liquid in the connecting pipe moves quickly towards the siphon, rapidly creating a siphon effect. Under these conditions, the required water volume for a single flush of the urinal can be reduced by about 23%. At the same time, the liquid rising into the extension pipe will also flow towards the siphon along the gap between the rotary valve and the siphon after the rotary valve is opened, preventing liquid stagnation.
[0020] 2. With the valve closed, the discharge will directly cause the liquid level in the extension pipe to rise after entering the discharge port (although it will eventually stop rising due to the increased air pressure in the extension pipe, the overall height will still be higher than the initial state). Therefore, the discharge volume can be determined by monitoring the liquid level in the extension pipe. Rotating the valve ensures that the function of this structure is completely unaffected by the connecting pipe, and the detection results are accurate and effective. The controller can control the water output of the water outlet mechanism according to the discharge volume to achieve water-saving function. Attached Figure Description

Detailed Implementation
[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] Reference Figures 1-9 This invention provides an energy-saving and environmentally friendly toilet device, comprising: a urinal 1, the bottom of which has a discharge port 2, the discharge port 2 being generally funnel-shaped to facilitate the rapid entry of excrement; a connecting pipe 3, one end of which is connected to the discharge port 2, and the other end of which is connected to a siphon pipe 4; an extension pipe 5, which is vertically arranged, its top closed, and its bottom connected to the connecting pipe 3, the connection point of the extension pipe 5 and the connecting pipe 3 being close to the connection point of the connecting pipe 3 and the siphon pipe 4; and a rotating valve 6, which is rotatably connected to the siphon pipe 4 between a first position and a second position. When the rotating valve 6 is in the first position, the rotating valve 6 closes the siphon pipe 4 and the connecting pipe 3 is connected to the extension pipe 5. When the rotating valve 6 is in the second position, the connecting pipe 3 is connected to the siphon pipe 4, and the extension pipe 5 is connected to the siphon pipe 4.
[0035] like Figure 2 and Figure 3As shown, the rotary valve 6 includes: an inner disc 601, a sealing rubber ring 602 provided on the outer edge of the inner disc 601, and a mounting hole 7 provided radially through the inner disc 601 and the sealing rubber ring 602. A rotating shaft is rotatably installed in the mounting hole 7, and the left and right ends of the rotating shaft are respectively fixedly connected to the inner sidewall of the siphon tube 4. The inner disc 601 and the sealing rubber ring 602 can rotate along the rotating shaft.
[0036] In some other embodiments, the sealing rubber ring 602 is shaped to fit the connection between the connecting pipe 3 and the siphon pipe 4. In this embodiment, the sealing rubber ring 602 has sufficient elasticity so that when it comes into contact with the inner wall of the siphon pipe 4, it can adaptively deform elastically and block the siphon pipe 4.
[0037] like Figure 2 and Figure 4 As shown, in this embodiment, it also includes: a telescopic motor 8, which is hinged to a first hinge seat 10 via a first hinge rod 9, and the output end of the telescopic motor 8 is hinged to a second hinge seat 12 via a second hinge rod 11. The second hinge seat 12 is fixedly mounted on the inner disc 601, and the telescopic motor 8 can drive the inner disc 601 to rotate between the first position and the second position. The second hinge seat 12 is located above the middle of the inner disc 601, and the first hinge seat 10 is fixedly mounted on the inner wall of the extension tube 5 and is a certain distance above the second hinge seat 12, so that the output rod of the telescopic motor 8 is generally inclined downward. When the inner disc 601 moves from the first position to the second position, the output end of the telescopic motor 8 pushes the top of the inner disc 601 to rotate towards the siphon tube 4; due to the special function of the siphon tube 4 in the toilet, the siphon tube 4 must be... Figure 2 As shown in the design, after adding the rotary valve 6, the rotary valve 6 can actually only move along... Figure 2 If you rotate it counterclockwise, it will be stuck on the inner wall of the siphon tube 4 if you rotate it clockwise.
[0038] like Figure 2 As shown, multiple liquid level sensors 13 are installed in the extension pipe 5 from bottom to top. The multiple liquid level sensors 13 are connected to the controller. After the liquid level sensors 13 at different heights come into contact with the liquid surface in the connecting pipe 3, they send different electrical signals to the controller. A water outlet mechanism is installed in the urinal 1. The controller receives different electrical signals and controls the water outlet mechanism to output different water volumes.
[0039] The specific work process is as follows:
[0040] like Figure 5 As shown, in the initial state, the rotating valve 6 is in the first position, at which time the liquid level in the connection is fixed and roughly horizontal with the bend of the siphon tube 4.
[0041] like Figure 6As shown, when someone uses urinal 1, the liquid level at the end of urinal 1 rises rapidly. The liquid in the connecting pipe 3 moves into the extension pipe 5. The air in the extension pipe 5 is compressed, generating pressure that causes the pressure in the extension pipe 5 to be greater than the pressure in urinal 1. At this time, it will produce... Figure 5 In the state shown, the liquid level in the urinal 1 is relatively high, and although the liquid level in the extension tube 5 has risen, it is still lower than the height of the urinal 1. At this time, the liquid level sensor 13 at the bottom of the extension tube 5 is completely submerged and sends an electrical signal to the controller.
[0042] like Figure 7 As shown, the controller controls the telescopic motor 8 to quickly move the rotary valve 6 from the first position to the second position (the stroke is short, taking about 0.3 seconds). The liquid rising in the extension pipe 5 flows rapidly into the siphon pipe 4 due to its own gravity. At this time, the liquid level in the siphon pipe 4 is lower than the liquid level in the urinal 1, quickly forming a siphon effect. The liquid in the connecting pipe 3 and the urinal 1 flows rapidly towards the siphon pipe 4. Simultaneously, the controller controls the water outlet mechanism to dispense water according to the water flow rate corresponding to the aforementioned electrical signal. The water outlet speed of the water outlet mechanism is much greater than the drainage speed in the connecting pipe 3. Therefore, the liquid level in the urinal 1 quickly changes to... Figure 8 The state shown.
[0043] After the water outlet mechanism flushes, the liquid in the connecting pipe 3 gradually decreases, eventually forming... Figure 9 The liquid level shown indicates that the controller controls the telescopic motor 8 to reset the rotary valve 6 from the second position to the first position, ready for the next use.
[0044] This invention discloses an energy-saving and environmentally friendly toilet device. An extension pipe 5 is added to the original structure. The top of the extension pipe 5 is closed, and its bottom end connects to the connecting pipe 3, forming a "semi-connecting device" structure with one end closed and the other open. When the urinal 1 is used, excrement flows into the urinal 1, increasing the liquid level at the outlet 2. The liquid level in the extension pipe 5 also increases. However, because the upper end of the extension pipe 5 is closed, the air pressure inside the extension pipe 5 increases, resulting in the liquid level in the urinal 1 being higher than that in the extension pipe 5. After opening the rotary valve 6, because the liquid level in the urinal 1 is much higher than the connection point between the siphon pipe 4 and the connecting pipe 3, the liquid in the connecting pipe 3 quickly moves towards the siphon pipe 4, rapidly forming a siphon effect. Under these conditions, the required water volume for a single flush of the urinal 1 can be reduced by approximately 23%. Simultaneously, the liquid rising into the extension pipe 5 also flows along the gap between the rotary valve 6 and the siphon pipe 4 after the rotary valve 6 is opened, preventing liquid stagnation. With valve 6 closed, the discharge entering the discharge port 2 will directly cause the liquid level in the extension pipe 5 to rise. Therefore, the discharge volume can be determined by monitoring the liquid level in the extension pipe 5. Rotating valve 6 can ensure that the function of this structure is completely unaffected by the connecting pipe 3. The detection results are accurate and effective. The controller can control the water output of the water outlet mechanism according to the discharge volume to achieve water saving function.
