Description

Technical Field

[0001] The utility model relates to the technical field of squatting pits, in particular to an intelligent water-saving squatting pit. Background Technique

[0002] A squatting pit refers to a place for defecation when using the toilet, and also refers to a squatting pan. A squatting pan is a toilet characterized by the human body taking a squatting position when in use. Squatting pans are divided into those without a shield and those with a shield; the structure of squatting pans has a water seal bend and no water seal bend. The working principle of the water seal bend is to use a horizontal S-shaped bend pipe to create a "water seal" to prevent the odor from the sewer from flowing back.

[0003] A water-saving squatting pit provided by the publication number "CN104594486B" includes a water storage squatting pit frame, a defecation squatting pit, and a stepping flushing device. The water storage squatting pit frame has a box-shaped structure and is connected to a washbasin. In the middle of the top plate of the water storage squatting pit frame, there is a squatting pit assembly opening. The defecation squatting pit is installed in the squatting pit assembly opening, and stepping flushing devices are provided on both sides thereof. The stepping flushing device is installed in the inner cavity of the water storage squatting pit frame, and its structure includes a suction flushing water tank and a stepping flushing water switch. The bottom of the suction flushing water tank is provided with a water suction valve pipe and a flushing valve pipe, and the flushing valve pipe is connected to the defecation squatting pit. In this embodiment, it can be connected to the washbasin individually or multiple ones can be connected to the washbasin side by side. The washing water used by people for washing is collected and stored in the water storage squatting pit frame for flushing the toilet, which not only reduces the use amount of tap water but also reduces the discharge amount of sewage. Therefore, this water-saving squatting pit has a reasonable structure, simple operation, and is convenient for people to save water.

[0004] However, the following problems still exist in the implementation process of the above device:

[0005] After the user defecates in the squatting pit, by pressing the switch on the water tank, the water in the water tank flows into the squatting pit, thereby flushing away the feces in the squatting pit. However, in this process, the situation where feces stick to the inner wall of the squatting pit often occurs, and the user has to press the switch multiple times for flushing, which will cause waste of water resources and thus reduce the practicability of the squatting pit. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an intelligent water-saving squatting pit to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] An intelligent water-saving squat toilet, comprising a squat toilet and a water tank. The connection between the water tank and the squat toilet is fixedly communicated through a transmission pipe. An infrared sensor is fixedly installed on one side of the water tank, and a PLC controller is fixedly installed on the other side of the water tank. The PLC controller is signal-connected to the infrared sensor. An electromagnetic valve is fixedly installed on the surface of the transmission pipe, and the electromagnetic valve is electrically connected to the PLC controller. A pressurization mechanism is arranged at the bottom of the water tank;

[0009] The pressurization mechanism includes an L-shaped bracket fixedly installed at the bottom of the water tank. The inner wall of the L-shaped bracket is fixedly connected with a pressurization box. The top of the pressurization box is fixedly communicated with an exhaust pipe. One side of the pressurization box is fixedly communicated with an intake pipe. An electric telescopic rod is fixedly installed at the bottom of the L-shaped bracket. The electric telescopic rod is electrically connected to the PLC controller. The output end of the electric telescopic rod penetrates into the interior of the L-shaped bracket and is fixedly connected with a push rod. The top of the push rod penetrates into the interior of the pressurization box and is fixedly connected with a push block. A discontinuous opening and closing mechanism is arranged on one side of the push rod.

[0010] Preferably, the discontinuous opening and closing mechanism includes a baffle arranged inside the transmission pipe. A rubber ring is fixedly connected to the surface of the baffle. One side of the baffle is fixedly connected with a rotating rod. One end of the rotating rod penetrates to the outside of the transmission pipe and is fixedly connected with a gear. A rotating hole matched with the rotating rod is opened on one side of the transmission pipe. One side of the push rod is fixedly connected with a connecting frame. One side of the connecting frame is fixedly connected with a rack matched with the gear.

[0011] Preferably, a sealing ring is fixedly connected to the inner wall of the rotating hole, and the sealing ring is made of silica gel.

[0012] Preferably, a torsion spring is sleeved on the surface of the rotating rod. One end of the torsion spring is fixedly connected with one side of the gear, and the other end of the torsion spring is fixedly connected with the surface of the transmission pipe.

[0013] Preferably, a first one-way valve is fixedly installed on the surface of the exhaust pipe, and a second one-way valve is fixedly installed on the surface of the intake pipe.

[0014] Preferably, a piston is fixedly connected to the top of the push block, and the outer surface of the piston contacts the inner wall of the pressurization box.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. By setting a pressurizing mechanism in the present utility model, when the user gets up after defecation, the infrared rays irradiated by the infrared sensor will be blocked for intelligent induction. Then, the signal is transmitted to the PLC controller, which will start the electric telescopic rod, causing the electric telescopic rod to drive the push rod, push block, and piston to move up and down reciprocally. When the piston moves upward, the gas in the pressurizing tank is compressed into the water tank. When the piston moves downward, a negative pressure is formed in the pressurizing tank, and the gas will enter the pressurizing tank through the intake pipe, circulating in turn to increase the pressure in the water tank. At the same time, the PLC controller will also start the solenoid valve, causing the water in the water tank to flow into the squat toilet through the transmission pipe. The air pressure in the water tank will push the water flow, making the water flow impact stronger, effectively flushing the feces, and thus achieving the effect of water conservation.

[0017] 2. By setting an intermittent opening and closing mechanism in the present utility model, after the push rod moves upward to a certain position, it will drive the toothed plate on the connecting frame to contact the gear, and the gear and the rotating rod will rotate. The rotating rod will drive the baffle and the rubber ring to rotate, opening the transmission pipe, so that the water flow is discharged into the squat toilet through the transmission pipe. When the push rod moves downward, the toothed plate will drive the gear, and the rotating rod, baffle, and rubber ring will reset to block the transmission pipe, thereby achieving the effect of controlling the intermittent discharge of water flow. Simply put, when the pressurizing mechanism discharges gas into the water tank, the baffle will open, and the water flow enters the squat toilet through the transmission pipe. During the air intake process of the pressurizing mechanism, the baffle is in a state of blocking the transmission pipe, further improving the water conservation effect and effectively enhancing the flushing effect.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1 - Figure 6 , the present invention provides a technical solution:

[0027] Embodiment 1:

[0028] An intelligent water-saving squatting pan, including a squatting pan 1 and a water tank 2. The connection between the water tank 2 and the squatting pan 1 is fixedly connected through a transmission pipe 3. An infrared sensor 4 is fixedly installed on one side of the water tank 2, and a PLC controller 5 is fixedly installed on the other side of the water tank 2. The PLC controller 5 is signal-connected to the infrared sensor 4. A solenoid valve 6 is fixedly installed on the surface of the transmission pipe 3, and the solenoid valve 6 is electrically connected to the PLC controller 5. A boosting mechanism is provided at the bottom of the water tank 2;

[0029] The boosting mechanism includes an L-shaped bracket 7 fixedly installed at the bottom of the water tank 2. The inner wall of the L-shaped bracket 7 is fixedly connected with a booster tank 8. The top of the booster tank 8 is fixedly communicated with an exhaust pipe 9. One side of the booster tank 8 is fixedly communicated with an intake pipe 10. An electric telescopic rod 11 is fixedly installed at the bottom of the L-shaped bracket 7. The electric telescopic rod 11 is electrically connected to the PLC controller 5. The output end of the electric telescopic rod 11 penetrates into the interior of the L-shaped bracket 7 and is fixedly connected with a push rod 12. The top of the push rod 12 penetrates into the interior of the booster tank 8 and is fixedly connected with a push block 13. A discontinuous opening and closing mechanism is provided on one side of the push rod 12.

[0030] In this embodiment, considering that after the user defecates in the squatting pan 1, by pressing the switch on the water tank 2, the water in the water tank 2 flows into the squatting pan 1, thereby flushing away the feces in the squatting pan 1. However, during this process, it often happens that feces stick to the inner wall of the squatting pan 1, and the user has to press the switch multiple times for flushing, which will cause waste of water resources and thus reduce the practicability of the squatting pan 1. Therefore, by setting a pressurizing mechanism, when the user gets up after defecating, the infrared rays irradiated by the infrared sensor 4 will be blocked for intelligent induction, and then the signal will be transmitted to the PLC controller 5. The PLC controller 5 will start the electric telescopic rod 11, so that the electric telescopic rod 11 drives the push rod 12, the push block 13 and the piston 25 to move up and down reciprocally. When the piston 25 moves upward, the gas in the pressurizing tank 8 will be compressed into the water tank 2. When the piston 25 moves downward, the pressure in the pressurizing tank 8 is negative, and the gas will enter the pressurizing tank 8 from the air inlet pipe 10 and circulate in turn to increase the pressure in the water tank 2. At the same time, the PLC controller 5 will also start the solenoid valve 6, so that the water in the water tank 2 flows into the squatting pan 1 from the transmission pipe 3. The air pressure in the water tank 2 will push the water flow, making the impact force of the water flow stronger, and thus effectively flushing the feces, and then achieving the effect of saving water;

[0031] It solves the problem that considering that after the user defecates in the squatting pan 1, by pressing the switch on the water tank 2, the water in the water tank 2 flows into the squatting pan 1, thereby flushing away the feces in the squatting pan 1. However, during this process, it often happens that feces stick to the inner wall of the squatting pan 1, and the user has to press the switch multiple times for flushing, which will cause waste of water resources and thus reduce the practicability of the squatting pan 1.

[0032] A first one-way valve 23 is fixedly installed on the surface of the exhaust pipe 9, and a second one-way valve 24 is fixedly installed on the surface of the air inlet pipe 10.

[0033] In this embodiment, by setting the first one-way valve 23 and the second one-way valve 24, where the first one-way valve 23 is a valve that can only admit air into the water tank 2, and the second one-way valve 24 is a valve that can only admit air into the pressurizing tank 8. Thus, when the piston 25 squeezes the gas in the pressurizing tank 8, the gas can only enter the water tank 2 from the exhaust pipe 9.

[0034] The top of the push block 13 is fixedly connected with a piston 25, and the outer surface of the piston 25 is in contact with the inner wall of the pressurizing tank 8.

[0035] In this embodiment, by setting the piston 25, the sealing performance between the push block 13 and the pressurizing tank 8 can be improved. When the push block 13 moves upward, the gas in the pressurizing tank 8 can be compressed.

[0036] Embodiment Two:

[0037] Based on the first embodiment, in this embodiment, the pressurizing mechanism can increase the air pressure in the water tank 2, thereby increasing the impact force of the water flow and improving the flushing effect, and further achieving the effect of water conservation. However, considering that if the water in the water tank 2 continuously flows out through the transmission pipe 3, the gas squeezed by the pressurizing mechanism is difficult to meet the function of enhancing the impact force of the water flow. The intermittent opening and closing mechanism in this application includes a baffle 14 arranged inside the transmission pipe 3. A rubber ring 15 is fixedly connected to the surface of the baffle 14. A rotating rod 16 is fixedly connected to one side of the baffle 14. One end of the rotating rod 16 penetrates to the outside of the transmission pipe 3 and is fixedly connected with a gear 17. A rotating hole 18 matching with the rotating rod 16 is opened on one side of the transmission pipe 3. A connecting frame 19 is fixedly connected to one side of the push rod 12. A rack 20 matching with the gear 17 is fixedly connected to one side of the connecting frame 19.

[0038] In this embodiment, considering that if the water in the water tank 2 continuously flows out through the transmission pipe 3, the gas squeezed by the pressurizing mechanism is difficult to meet the function of enhancing the impact force of the water flow. Therefore, by setting the intermittent opening and closing mechanism, after the push rod 12 moves upward to a certain position, the rack 20 on the connecting frame 19 will contact the gear 17. The gear 17 and the rotating rod 16 will rotate. The rotating rod 16 will drive the baffle 14 and the rubber ring 15 to rotate, opening the transmission pipe 3, so that the water flow is discharged from the transmission pipe 3 into the squatting pan 1. When the push rod 12 moves downward, the rack 20 will drive the gear 17, and the rotating rod 16, the baffle 14 and the rubber ring 15 will reset, blocking the transmission pipe 3, thereby achieving the function of controlling the intermittent discharge of the water flow. Simply put, when the pressurizing mechanism discharges gas into the water tank 2, the baffle 14 will open, and the water flow enters the squatting pan 1 through the transmission pipe 3. During the air intake process of the pressurizing mechanism, the baffle 14 is in a state of blocking the transmission pipe 3, further improving the water conservation effect and effectively improving the flushing effect at the same time.

[0039] It solves the problem that considering if the water in the water tank 2 continuously flows out through the transmission pipe 3, the gas squeezed by the pressurizing mechanism is difficult to meet the function of enhancing the impact force of the water flow.

[0040] A sealing ring 21 is fixedly connected to the inner wall of the rotating hole 18. The sealing ring 21 is made of silica gel.

[0041] In this embodiment, by setting the sealing ring 21, the sealing performance between the rotating rod 16 and the rotating hole 18 can be improved, and the water flow can be prevented from leaking from the rotating hole 18.

[0042] A torsion spring 22 is sleeved on the surface of the rotating rod 16. One end of the torsion spring 22 is fixedly connected to one side of the gear 17, and the other end of the torsion spring 22 is fixedly connected to the surface of the transmission pipe 3.

[0043] In this embodiment, by providing a torsion spring 22, the torsion generated by the torsion spring 22 can support structures such as the gear 17, the rotating rod 16, and the baffle 14, preventing the baffle 14 from rotating under the pressure of water flow and gas.

[0044] Working principle: When the user gets up after defecation, the infrared rays irradiated by the infrared sensor 4 will be blocked for intelligent sensing. Then, the signal is transmitted to the PLC controller 5, which will activate the electric telescopic rod 11, causing the electric telescopic rod 11 to drive the push rod 12, the push block 13, and the piston 25 to move up and down reciprocally. When the piston 25 moves upward, the gas in the pressure increasing tank 8 will be compressed into the water tank 2. When the piston 25 moves downward, a negative pressure is generated in the pressure increasing tank 8, and the gas will enter the pressure increasing tank 8 through the intake pipe 10. This cycle continues to increase the pressure in the water tank 2. At the same time, the PLC controller 5 will also activate the solenoid valve 6, causing the water in the water tank 2 to flow into the squat toilet 1 through the transmission pipe 3. The air pressure in the water tank 2 will push the water flow, making the water flow impact stronger, effectively flushing the feces, and thus achieving the effect of water conservation.

[0045] After the push rod 12 moves upward to a certain position, it will drive the toothed plate 20 on the connecting frame 19 to contact the gear 17, causing the gear 17 and the rotating rod 16 to rotate. The rotating rod 16 will drive the baffle 14 and the rubber ring 15 to rotate, opening the transmission pipe 3, allowing the water flow to drain from the transmission pipe 3 into the squat toilet 1. When the push rod 12 moves downward, the toothed plate 20 will drive the gear 17, and the rotating rod 16, the baffle 14, and the rubber ring 15 will reset, blocking the transmission pipe 3, thereby achieving the function of controlling the intermittent discharge of water flow. Simply put, when the pressure increasing mechanism discharges gas into the water tank 2, the baffle 14 will open, and the water flow will enter the squat toilet 1 through the transmission pipe 3. During the air intake process of the pressure increasing mechanism, the baffle 14 is in a state of blocking the transmission pipe 3, further improving the water conservation effect and effectively enhancing the flushing effect.

[0046] It should be noted that the infrared sensor 4, the PLC controller 5, the solenoid valve 6, and the electric telescopic rod 11 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Moreover, the specific composition and principle of the power supply of the infrared sensor 4, the PLC controller 5, the solenoid valve 6, and the electric telescopic rod 11 are clear to those skilled in the art, so they will not be elaborated in detail here.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
