Description

Technical Field

[0001] The utility model relates to a water-saving squat toilet, in particular to a high-efficiency flushing and water-saving squat toilet capable of adding a post-strong flush. Background Art

[0002] Existing water-saving squat toilets in public toilets: In most cases where flushing is easy, there is a problem of significantly surplus flushing volume, wasting water; in a few cases where flushing is not easy, there is a problem that flushing is not thorough once, and it must be flushed again, or even flushed twice, to be thorough. In order to solve this problem, the usual practice is to make the flushing volume compatible with easy flushing and difficult flushing, so as to avoid the situation of incomplete flushing as much as possible, thus wasting water; the latest practice is to reduce the size of the squat toilet's collection bucket, and relatively increase the flushing force of the collection bucket without increasing the flushing volume; however, in rare cases, the reduced collection bucket will cause defecation and urination outside the collection bucket, which greatly increases the cleaning burden, affects the normal use of the squat toilet, and damages the clean environment of the public toilet. In short, there is a problem of not being able to achieve efficient flushing.

[0003] There is a pre-flushing double-flush squat toilet with announcement number CN204676663U, which includes a squat toilet body fixed on the ground, a water seal elbow connected to the sewer is provided at the rear of the body, a flushing pipe I is provided at the rear end of the body, a valve I is provided on the flushing pipe I, a pre-flushing water channel is provided on the upper edge of the body; the pre-flushing water channel is connected to a flushing pipe II; the flushing pipe II is connected in series with a valve II; the flushing pipe II is connected to a pre-flushing water tank; the water inlet of the pre-flushing water tank is connected to the flushing pipe I. In order to ensure complete flushing, a flushing port is provided on the inner side of the front section of the upper edge of the body. In order to enable all-round flushing during the secondary flushing, the flushing pipe II between the valve II and the body is connected to the flushing pipe I through a pipe. In order to prevent water from flowing back to the water seal elbow, a one-way valve is provided on the pipe connecting the flushing pipe II and the flushing pipe I. Both the valve I and the valve II are electronic valves. A concave buffer groove is provided at the front of the body. Its advance flushing can significantly save water compared to the existing double flushing. However, its front and back flushing still has the problems of water waste and low flushing efficiency in most easy flushing situations. Utility Model Content

[0004] The utility model aims to overcome the above-mentioned defects of the prior art and provide a high-efficiency flushing and water-saving squat toilet with additional post-strong flushing. It can perform a single water-saving daily flushing in most cases to save water. If the flushing is not complete, a secondary strong flushing can be performed in a few cases to achieve a thorough flushing effect, thus realizing water-saving and efficient flushing.

[0005] To achieve the above-mentioned purpose, the utility model is a high-efficiency flushing and water-saving squat toilet with an additional strong back flush. The special feature of the utility model is that the squat toilet is provided with a flushing channel, a flushing hole and a total water inlet, or the squat toilet with a flushing channel and a flushing hole is respectively provided with a primary flushing water inlet and a secondary flushing water inlet connected to the flushing channel at the ends near and far from the lower discharge outlet; the secondary flushing water inlet or the total water inlet is connected to a water source pipe through a secondary flushing valve pipeline; the primary flushing water inlet or the total water inlet is connected to the output port of a soda-water mixing device through a primary foot valve pipeline suitable for most easy flushing situations, and the water inlet of the soda-water mixing device is connected to the water source pipe; or the primary flushing water inlet or the total water inlet is connected to the water source pipe through a primary foot valve pipeline suitable for most easy flushing situations. Compared with the one or two water inlets at the back and front, the flushing ability of the secondary flushing for difficult-to-flush objects can be significantly enhanced; compared with the one-time flushing with pure water, the one-time flushing with a mixture of soda and water can significantly save water; because the one-time flushing is applicable to most easy-to-flush situations, it can significantly save water for the one-time flushing compared with the existing flushing that is compatible with easy flushing and difficult flushing, and because the secondary flushing is a flushing in a few cases, it can save water overall compared with the majority and the minority, and can solve the problem of difficult flushing. In this way, after going to the toilet, in most cases, you can step on the foot valve once to perform daily water-saving soda-water mixed flushing or pure water flushing through the one-time foot valve pipeline applicable to most easy-to-flush situations, so as to meet the normal flushing in daily easy-to-flush situations and play a water-saving role. If it is found that the one-time water-saving flushing applicable to most easy-to-flush situations is not flushed, you can also open the secondary flushing valve and perform a strong flushing in a few cases through the secondary flushing valve pipeline, so as to achieve a thorough flushing effect. Of course, the second flushing can also be a combined flushing of the one and two flushes through the linkage mechanism, which can further enhance the flushing ability. It has the function of performing a water-saving daily flushing with soda and water which is suitable for most easy-to-flush situations, thus saving water. If flushing is not thorough, a secondary strong flushing or a one-two combined flushing can be performed in a few cases to solve the problem of difficult flushing and achieve the advantages of water-saving flushing and efficient flushing.

[0006] As an optimization, the secondary flushing valve is a secondary foot valve used separately from the primary foot valve. In this way, when flushing once, only the foot valve is stepped on once, and when flushing twice, the secondary foot valve is stepped on again, which is convenient for separate pipeline settings.

[0007] As an optimization, the primary foot valve and the secondary foot valve are respectively equipped with eye-catching applicable labels. The primary foot valve is flushed daily according to the applicable labels for guidance, and the secondary foot valve is flushed strongly according to needs and instructions, which is convenient for correct use. The applicable labels, such as the primary normal flushing foot valve and the secondary strong flushing foot valve.

[0008] As an optimization, the applicable signs are set on the ground or wall near the primary foot valve and the secondary foot valve without any additional settings, which is convenient for identification and setting.

[0009] As an optimization, the primary foot valve and the secondary foot valve are both arranged on the ground, and the arrangement positions satisfy that: the primary foot valve is more convenient to step on than the secondary foot valve. The primary foot valve with high utilization rate is convenient to step on and is also conducive to correct selection.

[0010] As an optimization, the distance between the primary foot valve and the squat toilet is greater than that between the secondary foot valve and the squat toilet. This is convenient for the primary foot valve with high utilization rate and is also conducive to the correct selection of the pedal.

[0011] As an optimization, the primary foot valve and the secondary foot valve are respectively arranged on the ground and on the vertical pipe or wall surface close to the wall. In this way, it is more conducive to avoiding the mistake of stepping on the secondary foot valve.

[0012] As an optimization, the secondary flushing valve is a secondary foot valve in parallel with the primary foot valve, and the primary foot lever of the primary foot valve and the secondary foot lever of the secondary foot valve are configured with a dual-purpose foot device through an automatic switching return device or an intelligent electric switching return device. In this way, when you step on it for the first time, you step on the primary foot valve, and it automatically or intelligently switches to the secondary foot valve position. When you step on it again, you step on the secondary foot valve. If you do not step on it for a long time, the automatic switching return device or the intelligent electric switching return device will automatically return to the primary foot valve position.

[0013] As an optimization, the automatic switching return device consists of an automatic switching mechanism and a delayed return mechanism; the automatic switching mechanism relies on pedal force to drive the switching position between the connecting branch between the primary pedal rod and the dual-purpose pedal device and between the connecting branch between the secondary pedal rod and the dual-purpose pedal device, or relies on pedal force to generate electricity to drive the switching position between the connecting branch between the primary pedal rod and the dual-purpose pedal device and between the connecting branch between the secondary pedal rod and the dual-purpose pedal device; the position between the secondary pedal rod and the dual-purpose pedal device that has not been stepped on returns to the position between the connecting branch between the primary pedal rod and the dual-purpose pedal device under the drive of the delayed return mechanism.

[0014] The intelligent electric switching and returning device is electrically connected to the human body sensor; the human body sensor senses the human body signal and starts the intelligent electric switching and returning device. The initial working position of the intelligent electric switching and returning device is connected between the primary foot pedal and the dual-purpose foot pedal device. When the dual-purpose foot pedal device is stepped on after using the toilet, the foot valve pipeline is flushed once. When the foot valve is stepped on or stepped back, the working position of the intelligent electric switching and returning device is moved to the connecting position between the secondary foot pedal and the dual-purpose foot pedal device. When the dual-purpose foot pedal device is stepped on again, the secondary foot valve pipeline is flushed. The human body sensor loses the human body signal, and the working position of the intelligent electric switching and returning device is moved back to the connecting position between the primary foot pedal and the dual-purpose foot pedal device.

[0015] As an optimization, the primary foot valve is electrically connected to the human body sensor through a linkage switch, and the secondary flushing valve is a secondary flushing electric control valve electrically connected to the human body sensor. When the foot valve is stepped on once, the primary foot valve pipeline is flushed, and the human body sensor is activated through the linkage switch. When the foot valve is stepped on again, the primary foot valve and the secondary flushing electric control valve are opened at the same time, and the primary foot valve pipeline and the secondary flushing valve pipeline are strongly flushed together to solve the problem of difficult flushing. Compared with the strong flushing of the secondary flushing valve pipeline only, a part of the flushing water volume of the secondary flushing valve pipeline can be relatively saved, and it is replaced by the soda-water mixed flow of the primary foot valve pipeline, thereby further saving water on the basis of solving the problem of difficult flushing, which is more simple and practical.

[0016] After adopting the above technical scheme, the utility model can add a high-efficiency flushing and drainage water-saving squat toilet with a strong back flush. It can perform a water-saving soda-water mixed daily flushing suitable for most easy flushing situations, which plays a role in saving water. If it cannot be flushed completely, a secondary strong flush or a one-two combined flush can be performed in a few cases to solve the problem of difficult flushing and achieve the advantages of water-saving flushing and efficient drainage.

Compared with the rear and front having one or two water inlets, the flushing ability of the secondary flushing on the difficult-to-flush objects can be significantly enhanced; compared with the primary flushing of the soda-water mixture, the primary flushing can significantly save water; because the primary flushing is applicable to most easy flushing situations, compared with the existing flushing that is compatible with easy flushing and difficult flushing, it can significantly save water for the primary flushing; and because the secondary flushing is a flushing in a few cases, it can save water and solve the difficult flushing problem in general compared with the few cases.

It can also be driven by pedaling force to switch the working position between the connecting branch between the primary pedal rod and the dual-purpose pedal device 8 and between the connecting branch between the secondary pedal rod and the dual-purpose pedal device 8. The working position between the connecting branch between the secondary pedal rod and the dual-purpose pedal device that is not stepped on is driven by the delayed returning mechanism to return to the working position between the connecting branch between the primary pedal rod and the dual-purpose pedal device.

The intelligent electric switching return device is electrically connected to the human body sensor 7; the human body sensor senses the human body signal and starts the intelligent electric switching return device. The initial working position of the intelligent electric switching return device is connected between the primary foot pedal and the dual-purpose foot pedal device.

When the foot valve is stepped on or stepped back, the working position of the intelligent electric switching return device is moved to the connecting branch between the secondary foot pedal and the dual-purpose foot pedal device. When the dual-purpose foot pedal device is stepped on again, the secondary foot valve pipeline is flushed. The human body sensor loses the human body signal, and the working position of the intelligent electric switching return device is moved back to the connecting branch between the primary foot pedal and the dual-purpose foot pedal device.

[0029] Embodiment 5, as Figure 5 As shown, the difference between the high-efficiency flushing and water-saving squat toilet with additional strong back flushing of the utility model and the above-mentioned embodiment 1 is that the primary foot valve 2 is electrically connected to the human body sensor 7 through a linkage switch, and the secondary flushing valve is a secondary flushing electric control valve 31 electrically connected to the human body sensor 7. When the foot valve is stepped on once, the primary foot valve pipeline is flushed, and the human body sensor is activated through the linkage switch.
