As shown in fig. 1-6, the embodiment provides a splash-proof mechanism for a toilet bowl, which comprises a water tank 1, a foam generating tank 3, and a foaming agent tank 2 arranged at the upper end of the foam generating tank 3 and used for storing foaming agent; the lower end of the foam generating box 3 is connected with a foam conveying pipe 4, and the tail end of the foam conveying pipe 4 extends into the excrement pool; a spiral foaming device 3-1 is arranged in the foam generating box 3 and is used for foaming a foaming agent into foam; the splash-proof mechanism of the toilet bowl further comprises a liquid level detection sensor 5, wherein the liquid level detection sensor 5 is arranged at the lower part of the water tank 1, and controls the spiral foaming device 3-1 to work when detecting that the water level in the water tank 1 reaches the lowest point.

The anti-splashing mechanism of the toilet bowl type closestool mainly changes the foaming agent into foam to cover the accumulated water of the trap of the urinal, the strong tension on the surface of the foam can greatly buffer the impulsive force of excrement entering water, and splashed water can be firmly sealed by the foam layer covered on the anti-splashing mechanism when entering water. In the embodiment, the foaming agent box 2 is arranged at the upper end of the water tank 1, and foaming agent can be filled at any time to provide a main source of foam for the splash-proof mechanism of the pedestal pan type closestool. The foam generating tank 3 is provided in the water tank 1. When the device is arranged, the foam generating box 3 is arranged in a space (the size adopts the actual size of a toilet bowl in a home) which is 12.5cm long, 12.5cm wide and 12-18cm high and is arranged in the water tank 1, the upper end of the foam generating box 3 is connected with the foaming agent box 2, so that the foaming agent in the foaming agent box 2 flows downstream to the foam generating box 3, and the foaming agent is changed into foam in the foam generating box 3 under the action of the spiral foaming device 3-1. This mechanism is at the during operation, detect the water level in the water tank 1 through level detection sensor 5, water in the water tank 1 can be taken away when washing by water, just show to wash by water and accomplish when taking out the certain degree, level detection sensor 5 sets up the liquid level department (or slightly on the upper side) after having taken out water in the water tank 1, when detecting the water level in the water tank 1 and being less than this liquid level, control spiral foaming device 3-1 work, accomplish the process that the foamer becomes the foam, the foam that produces passes through foam conveyer pipe 4 in the foam generator, get into in the urinal, cover on the surface of water of trap, and then prevent to dabble.

In the embodiment, the spiral foaming device 3-1 comprises a spiral foaming rod 3-11 and a foaming shell 3-12 sleeved outside the spiral foaming rod 3-11; the foaming shell 3-12 is provided with a foam outlet 3-121 communicated with the interior of the foam generating box 3; the spiral foaming rod 3-11 is used for foaming the foaming agent in the spiral foaming device 3-1 into foam, and the foam enters the foam generating box 3 through the foam outlet 3-121. The foaming agent flows into the foam generating box 3 from the foaming agent box 2, and is stirred into foam mainly under the stirring action of the spiral foaming rods 3-11. Wherein, the spiral foaming rod 3-11 comprises a foaming agent storage part 3-111 provided with a foaming agent storage chamber 3-1111 inside and a thread 3-1112 arranged on the outer side wall of the foaming agent storage part 3-111; the foaming agent storage part 3-111 is provided with a foaming agent inlet 3-1113 for communicating the foaming agent storage cavity 3-1111 with the foaming agent box 2, and the side wall of the foaming agent storage part 3-111 is provided with a foaming agent outlet 3-1114 communicated with the foaming agent storage cavity 3-1111. The foaming agent in the foaming agent box 2 directly enters the foaming agent storage cavity 3-1111 from the foaming agent inlet 3-1113, when the liquid level of the foaming agent stored in the foaming agent storage cavity 3-1111 reaches the foaming agent outlet 3-1114, the foaming agent flows out of the foaming agent outlet 3-1114 onto the thread 3-1112 on the outer side wall of the foaming agent storage part 3-111, and when the spiral foaming rod 3-11 rotates to work, the foaming agent on the thread 3-1112 is foamed under the high-speed rotation action of the thread 3-1112. There are a plurality of blowing agent outlet holes 3-1114, and in this embodiment, in order to prevent blowing agent from flowing out too quickly in blowing agent storage chamber 3-1111, blowing agent outlet holes 3-1114 have a diameter of 1-2 mm. Wherein, thread grooves 3-1115 are formed between the threads 3-1112; the foaming agent outlet hole 3-1114 is arranged at the thread groove 3-1115. Under the action of high-speed rotation of the spiral foaming rods 3-11, centrifugal movement of the foaming agent cannot be avoided, if the peripheries of the spiral foaming rods 3-11 are not limited in space or are large in space, the foaming agent cannot be fully stirred into foam by the spiral foaming rods 3-11, the foaming agent may fall into the bottom end of the foam generator without the action of the spiral foaming rods 3-11, and then directly enters the urinal along the foam conveying pipe 4, sufficient foam cannot be generated, and waste of the foaming agent is caused. Therefore, the foaming shell 3-12 is sleeved outside the foaming agent storage part 3-111, and a foaming space for foaming is formed between the foaming shell and the foaming agent storage part 3-111; the foam outlet 3-121 has a plurality of foam outlets 3-121 communicating with the foaming space.

And because the liquid foaming agent becomes foam and then the volume becomes larger, a plurality of foam outlets 3-121 for foam to overflow are arranged around the foaming shell 3-12. The foam which is excessive in the foaming space can directly enter the foam generating box 3 through the foam outlets 3-121 and then enter the excrement pool along the foam conveying pipe 4 at the lower end of the foam generating box.

Wherein, the lower end of the spiral foaming rod 3-11 is connected with a motor 3-13 for the spiral foaming rod 3-11 to work. The spiral foaming rod 3-11 is driven to work by a motor 3-13 at the lower end of the spiral foaming rod, and the spiral foaming rod 3-11 is connected with the motor 3-13 by a coupler 3-14. So that the spiral foaming rod 3-11 is rotated with the rotation of the motor 3-13. In addition, the closestool splash-proof mechanism also comprises a singlechip; the liquid level detection sensor 5 and the motors 3-13 are connected with the single chip microcomputer. The single chip provides electric support through the power supply, a voltage converter is connected between the power supply and the single chip, the voltage converter can convert 220V power supply voltage into 24V, and the motors 3-13 are prevented from being burnt due to overlarge voltage. Meanwhile, the liquid level detection sensor 5 and the motors 3-13 are both connected with the single chip microcomputer, when the liquid level detection sensor 5 detects that the water level in the water tank 1 is lower than the lowest water level, a signal is sent to the single chip microcomputer, then the single chip microcomputer controls the motors 3-13 to work, the spiral foaming rods 3-11 are driven to work, and the foaming agent is foamed. The single chip microcomputer controls the motors 3-13 to automatically stop after working for a set time so as to prevent excessive foam deposition in the urinal and prevent excessive foaming agent waste.

In this embodiment, the liquid level detection sensor 5 is disposed in the water tank 1, and the distance from the bottom end of the water tank 1 is 1/5-1/2 of the water tank 1. According to the water level setting after the water in the water tank 1 is pumped and stopped when the water closet is flushed.
