Due to the influence of environmental temperature differences and other issues, the use of toilets has a certain scope of application. In the cold north, the temperature is often below zero, and the water tank in the toilet will freeze due to the low temperature, making it impossible to flush.

[0003] In the existing market, there is a method of providing hot water to the water in the water tank by connecting a three-way hot water pipe. However, the overall water volume in the water tank is large, and the heat provided by the hot water is not enough to thaw the water, resulting in low flushing efficiency and complex maintenance. Summary of the invention

[0026] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 3 :

[0027] A freeze protection mechanism for a toilet comprises a toilet seat 1 with a toilet bowl 2 mounted on its upper end surface, a water injection chamber 10 and an installation chamber 11 located at the bottom of the toilet bowl formed by a high partition 3 in the toilet seat 1, a heating rod 4 and a water pump 5 for flushing the toilet bowl 2 are fixed to the bottom of the water injection chamber 10, the heating rod 4 and the water pump 5 are connected to a PCB board 6 in the toilet via a wire 40, a water injection pipe 7 communicating with the water injection chamber 10 is arranged on one side of the high partition 3, and a bottom sewage pump 12 for connecting to the bottom sewage outlet of the toilet bowl 2 is fixed in the installation chamber 11.

[0028] In the above structure, the water filling chamber 10 formed by the high partition 3 of the toilet seat serves as the water tank of the toilet. A heating rod is provided at the bottom to continuously heat the water tank to prevent it from freezing in a cold environment. In addition, compared with the traditional method of installing a heater on the pipeline, this design heats the water in the water tank to ensure that it can be used immediately when the flushing function is used, without the need to thaw it first and then flush it as in the traditional way.

[0029] During the water filling process, the water in the water injection chamber is preferentially used for flushing through the water pump 5, and the sewage at the bottom of the toilet bowl is discharged through the pipeline and the sewage pump 12, that is, the water in the water injection chamber and the sewage discharge process do not affect each other.

[0030] Preferably, a short partition 30 is provided at the bottom of the water injection chamber 10 , a short water trough 31 is formed between the short partition 30 and the high partition 3 , and the heating rod 4 is located in the short water trough 31 .

[0031] In the above structure, the short water tank 31 formed can still have a certain amount of water when the water in the water injection chamber is completely released by the water pump, ensuring that the water in the short water tank 31 can continue to provide a temperature upper limit for the heating rod, effectively preventing the heating rod from dry burning, and extending the service life of the heating rod.

[0032] Preferably, a plurality of heating rod brackets are fixed in the short water tank 31 , and the heating rod brackets include a suction cup 41 whose bottom is in contact with the bottom of the short water tank 31 , and a “C”-shaped clamp 42 for clamping the heating rod 4 is provided above the suction cup 41 .

[0033] During the implementation process, when the heating rod heats the water, a certain heating movement will occur, or when the water pump draws water from the water injection chamber, a certain water flow will be generated. The above will cause the heating rod to have a certain displacement. The use of a heating rod bracket can effectively fix it and prevent the heating rod from slipping out of the short water tank.

[0034] Preferably, one end of the water injection pipe 7 extends out of the installation cavity 11 and is connected to a water source, and the other end of the water injection pipe 7 is connected to a water level limiter 70 located in the water injection cavity 10, and the water level limiter 70 is fixed to the side wall of the high partition 3 through a limiter bracket 71.

[0035] In the above structure, the water level limiter 70 can keep the water level in the water injection cavity at an appropriate liquid level to prevent excess water from flowing into the installation cavity.

[0036] Preferably, a mounting frame 13 is fixed to the upper edge of the toilet seat 1, a toilet bowl mounting hole 20 for mounting the toilet bowl 2 is opened on the front side of the mounting frame 13, a board groove 60 for mounting the PCB board 6 is fixed on the rear side of the mounting frame 13, one end of the wire 40 is fixed on the PCB board 6, and the other end thereof crosses the high partition board 3 and is connected to the heating rod 4 and the end of the water pump 5.

[0037] It is worth mentioning that there are two wires connecting the heating rod and the water pump, and one end is fixed on the PCB board, and the other end is connected to their respective components.

[0038] Preferably, the water pump 5 includes a water inlet pipe 50 connected to the bottom of the water injection chamber 10 at one end, and a water outlet pipe 51 connected to the upper edge of the toilet bowl 2 at the other end of the water pump 5 .

[0039] During the implementation process, the mouth of the water inlet pipe should be facing downwards, so that more water can be absorbed into the water injection cavity to prevent liquid accumulation.

[0040] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
