Description

Technical Field

[0001] The invention relates to the technical field of toilet antifreeze and water saving, in particular to an electric antifreeze toilet. Background Art

[0002] The toilet, also known as a water closet or toilet seat, is an indispensable sanitary device in modern homes, public facilities and commercial places. It is mainly used for the collection and treatment of excrement, and discharges the waste into the sewer system through a water flushing system. In cold seasons, especially in areas where the temperature may drop below zero in winter, toilets and their water supply systems are susceptible to freezing damage, leading to problems such as pipe rupture and water tank damage. A special insulation cover is installed for the toilet tank, usually made of foam plastic or rubber, which can effectively isolate the external cold air and maintain the water temperature in the tank. In addition, in rural areas without pipe networks, there is no tap water, water use is inconvenient and there is a shortage of water, and septic tanks are used to store feces and sewage. The septic tank has a small capacity, and the use of traditional water-flushing toilets consumes a lot of water, resulting in frequent extraction of the septic tank.

[0003] There are still some problems in the use of existing antifreeze toilets. An appropriate amount of food-grade antifreeze is added to the water tank to lower the freezing point of water and prevent freezing. However, the addition of antifreeze is not convenient to calculate, and too much antifreeze can easily corrode toilet parts. Alternatively, an insulation structure is set to prevent cold air from entering, but it will also cause freezing over a long period of time. Therefore, those skilled in the art provide an electric antifreeze toilet to solve the problems raised in the above background technology. Summary of the Invention

[0004] (1) Technical problems solved In response to the deficiencies in the prior art, the present invention provides an electric antifreeze toilet, which solves the problem of adding an appropriate amount of food-grade antifreeze into the water tank to lower the freezing point of water and prevent freezing. However, the addition of antifreeze is not convenient to calculate, and excessive antifreeze can easily corrode toilet components. Alternatively, an insulating structure is provided to prevent cold air from entering, but this can also cause freezing over a long period of time. There are also problems with septic tank capacity, the lack of tap water in rural areas in the north, and the inconvenience of water use and water shortage.

[0005] (2) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: an electric antifreeze toilet, comprising a toilet body, a toilet cover provided at the front center of the upper end surface of the toilet body, a water storage tank provided at the rear center of the upper end surface of the toilet body, and a control box provided at the rear end surface of the water storage tank; The water storage tank includes a water tank body, the upper end surface of the water tank body is provided with a top cover, the lower inner wall of the water tank body is provided with a carbon steel anti-dry burning heating rod near the edge, a plurality of temperature sensors are arranged in an upper and lower arrangement at the center of the front inner wall of the water tank body, and a water spray structure is provided at one side of the center of the lower inner wall of the water tank body; The water spraying structure includes a quantitative water tank. The ceramic water tank changes the original structure so that the water tank capacity reaches 25 liters. The upper end surface of the quantitative water tank is fixedly connected to a connecting pipe. The output end of the pressurized water pump is fixedly connected to a connecting pipe. The end of the connecting pipe is provided with a water spraying seat. The lower end surface of the water spraying seat is laterally arranged with leakage holes. Through power pressure, the water outlet holes can achieve a spraying effect, and a limited amount of water is used to flush feces and sewage into the sewer pipe. The flushing volume is about 0.5 liters each time, which is different from the traditional toilet flushing once and filling the water once. A full tank of water can be flushed multiple times to achieve a water-saving effect. The water inlet method adopts two methods: connecting to tap water or injecting water. If there is no tap water, it can be injected for use, which solves the problem of no tap water. It is inconvenient to use. It can be flushed multiple times after filling with water. In addition, it can be injected with domestic sewage to solve the problem of water shortage or inconvenience in using water. The water temperature inside the water tank body is detected by multiple temperature sensors, and the temperature threshold is set by the programmable control chip. By setting the threshold from two degrees to six degrees, when the water temperature inside the water tank body is lower than two degrees, the programmable control chip controls the carbon steel anti-dry burning heating rod to energize and heat the water inside the water tank body. After heating to six degrees, multiple temperature sensors detect that the temperature has reached the threshold and send a pulse signal to the programmable control chip. The programmable control chip then cuts off the power to the carbon steel anti-dry burning heating rod and no longer heats the water inside the water tank body.

[0006] Preferably, the toilet body includes a toilet seat, a toilet bowl is provided at the front center of the upper end surface of the toilet seat, a flange self-priming anti-odor valve is provided at the lower part of the toilet bowl, the water spray seat and one end of the connecting pipe pass through the lower inner wall of the water tank body and the upper end surface of the toilet seat to the rear inner wall of the toilet bowl, and the water spray seat is fixedly connected to the rear inner wall of the toilet bowl, and the pressurized water pump draws out the water inside the quantitative water tank, transports it to the inside of the water spray seat through the connecting pipe, and sprays it out through multiple leakage holes at the bottom and side of the water spray seat, so as to facilitate flushing of excrement inside the toilet bowl.

[0007] Preferably, the flange self-priming anti-odor valve includes an outer tube, a rubber pad is provided at the upper part of the outer tube, a round tube is sleeved inside the rubber pad, and the lower end surface of the round tube is rotatably connected to a silicone counterweight plate. It is arranged in a straight-through type, and a small amount of water can flush excrement out of the toilet bowl.

[0008] Preferably, the silicone counterweight plate is composed of a counterweight block and a silicone sleeve, the silicone sleeve is arranged on the outside of the counterweight block, and one end of the silicone sleeve is fixedly connected to the lower end surface of the circular tube. During the flushing process, the water pressure impacts the silicone counterweight plate downward, causing the silicone counterweight plate to flip along the position where the silicone counterweight plate is connected to the circular tube. After the water is flushed down, the silicone counterweight plate is restored to its original state according to the restorability of the silicone on the silicone counterweight plate itself. There is no magnet and spring setting, which reduces the probability of equipment failure.

[0009] Preferably, a water inlet pipe is provided at one end of the lower inner wall of the water tank body away from the water spray structure. The water inlet pipe passes through the lower inner wall of the water tank body and the upper end surface of the toilet body and reaches the rear end of the toilet body, and a water inlet valve is fixedly connected to the end. By opening the water inlet valve and connecting the water pipe, it is convenient to replenish water into the water tank body.

[0010] Preferably, a programmable control chip is provided inside the control box, and the water temperature inside the water tank body is precisely adjusted by the programmable control chip.

[0011] Preferably, the capacity of the quantitative water tank is 250 ml, and the pressure water pump delivers 250 ml each time, which reduces the amount of water for flushing and reduces the waste of water resources.

[0012] Preferably, a heat insulating layer is provided on the inner wall of the water tank body, and the heat insulating layer reduces the heat exchange between the water inside the water tank body and the external temperature, resulting in rapid cooling of the water inside the water tank body.

[0013] (3) Beneficial effects The present invention provides an electric antifreeze toilet with the following beneficial effects: 1. In the present invention, the water temperature inside the water tank body is detected by multiple temperature sensors, and the temperature threshold is set by a programmable control chip. By setting the threshold from two degrees to six degrees, when the water temperature inside the water tank body is lower than two degrees, the programmable control chip controls the carbon steel anti-dry burning heating rod to be energized to heat the water inside the water tank body. After heating to six degrees, multiple temperature sensors detect that the temperature has reached the threshold and send a pulse signal to the programmable control chip. The programmable control chip then cuts off the power to the carbon steel anti-dry burning heating rod and no longer heats the water inside the water tank body.

[0014] 2. In the present invention, the delivered water is stored in a quantitative water tank. When flushing, the pressure water pump is started by the control box to pump out the water inside the quantitative water tank, and transport it to the inside of the water spray seat through a connecting pipe. The water is sprayed out through multiple leakage holes at the bottom and side of the water spray seat. Since it is a straight-through type, a small amount of water can flush the excrement out of the toilet.

[0015] 3. In the present invention, during the flushing process, the water pressure impacts the silicone counterweight plate downward, causing the silicone counterweight plate to flip along the position where the silicone counterweight plate is connected to the round tube. After the water is flushed down, the silicone counterweight plate is restored to its original state according to the restorability of the silicone on the silicone counterweight plate. There is no magnet and spring setting, which reduces the probability of equipment failure. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: like Figure 1-6 As shown, an embodiment of the present invention provides an electric antifreeze toilet, including a toilet body 1, a toilet cover 4 is provided at the front center of the upper end surface of the toilet body 1, a water tank 2 is provided at the rear center of the upper end surface of the toilet body 1, and a control box 3 is provided at the rear end surface of the water tank 2 to facilitate integrated control through the control box 3.

[0020] like Figure 1 、 2 As shown in Figures 3, 4 and 6, the water tank 2 includes a water tank body 201, a top cover 202 is provided on the upper end surface of the water tank body 201, a carbon steel anti-dry burning heating rod 206 is provided at the edge of the lower inner wall of the water tank body 201, a plurality of temperature sensors 205 are arranged in an upper and lower arrangement at the center of the front inner wall of the water tank body 201, and a water spray structure 204 is provided at one side of the center of the lower inner wall of the water tank body 201. The water spray structure 204 facilitates the transportation of water to the interior of the toilet body 1 for flushing.

[0021] The water spraying structure 204 includes a quantitative water tank 2041. The ceramic water tank changes the original structure to make the water tank capacity reach 25 liters. The upper end surface of the quantitative water tank 2041 is fixedly connected to a connecting pipe 2043. The output end of the pressurized water pump 2042 is fixedly connected to the connecting pipe 2043. The end of the connecting pipe 2043 is provided with a water spraying seat 2044. The lower end surface of the water spraying seat 2044 is laterally arranged with leakage holes 2045. Through power pressure, the water outlet holes can achieve a spraying effect, and a limited amount of water is used to flush the feces and sewage into the sewer pipe. The water flushing volume is about 0.5 liters each time, which is different from the traditional toilet flushing once and lasting water once. A full tank of water can be flushed multiple times to achieve a water-saving effect. The water inlet method adopts two methods: connecting to tap water or injecting water. If there is no tap water, it can be injected for use, which solves the problem of no water. Tap water is inconvenient to use, so it can be filled with water for flushing multiple times. In addition, domestic sewage can be injected for use to solve the problem of water shortage or inconvenience in using water. The water temperature inside the water tank body 201 is detected by multiple temperature sensors 205, and the temperature threshold is set by the programmable control chip. By setting the threshold from two degrees to six degrees, when the water temperature inside the water tank body 201 is lower than two degrees, the programmable control chip controls the carbon steel anti-dry burning heating rod 206 to be energized to heat the water inside the water tank body 201. After heating to six degrees, multiple temperature sensors 205 detect that the temperature has reached the threshold and send a pulse signal to the programmable control chip. The programmable control chip then cuts off the power to the carbon steel anti-dry burning heating rod 206 and no longer heats the water inside the water tank body 201.

[0022] like Figure 1 、 2 As shown in Figures 3 and 5, the toilet body 1 includes a toilet seat 101, a toilet bowl 102 is provided at the front center of the upper end surface of the toilet seat 101, and a flange self-priming anti-odor valve 103 is provided at the lower part of the inside of the toilet bowl 102. The water spray seat 2044 and one end of the connecting pipe 2043 pass through the lower inner wall of the water tank body 201 and the upper end surface of the toilet seat 101 to the rear inner wall of the toilet bowl 102, and the water spray seat 2044 is fixedly connected to the rear inner wall of the toilet bowl 102. The pressurized water pump 2042 draws out the water from the quantitative water tank 2041, and transports it to the inside of the water spray seat 2044 through the connecting pipe 2043, and sprays it out through multiple leakage holes 2045 at the bottom and side of the water spray seat 2044, so as to facilitate flushing of excrement inside the toilet bowl 102.

[0023] The flange self-priming anti-odor valve 103 includes an outer tube 1031, a rubber pad 1032 is provided at the upper part of the outer tube 1031, a round tube 1033 is sleeved inside the rubber pad 1032, and the lower end surface of the round tube 1033 is rotatably connected to a silicone counterweight plate 1034. It is a straight-through type, and a small amount of water can flush excrement out of the toilet bowl 102.

[0024] The silicone counterweight plate 1034 consists of a counterweight block and a silicone sleeve. The silicone sleeve is arranged on the outside of the counterweight block, and one end of the silicone sleeve is fixedly connected to the lower end surface of the circular tube 1033. During the flushing process, the water pressure will impact the silicone counterweight plate 1034 downward, causing the silicone counterweight plate 1034 to flip along the position where the silicone counterweight plate 1034 is connected to the circular tube 1033. After the water is flushed down, the silicone counterweight plate 1034 is restored to its original state according to the restorability of the silicone on the silicone counterweight plate 1034. There is no magnet or spring setting, which reduces the probability of equipment failure.

[0025] A water inlet pipe is provided at one end of the lower inner wall of the water tank body 201 away from the water spray structure 204. The water inlet pipe passes through the lower inner wall of the water tank body 201 and the upper end surface of the toilet body 1 and reaches the rear end of the toilet body 1. A water inlet valve 203 is fixedly connected to the end. By opening the water inlet valve 203 and connecting the water pipe, it is convenient to replenish water into the water tank body 201.

[0026] A programmable control chip is provided inside the control box 3 , and the water temperature inside the water tank body 201 is precisely adjusted by the programmable control chip.

[0027] The capacity of the quantitative water tank 2041 is 250 ml, and the pressure water pump 2042 delivers 250 ml each time, which reduces the amount of water for flushing and reduces the waste of water resources.

[0028] An insulation layer is provided on the inner wall of the water tank body 201 , which reduces the heat exchange between the water inside the water tank body 201 and the external temperature, causing the water inside the water tank body 201 to cool down quickly.

[0029] Working principle: When in use, the water temperature inside the water tank body 201 is detected by multiple temperature sensors 205, and the temperature threshold is set by the programmable control chip. By setting the threshold from two degrees to six degrees, when the water temperature inside the water tank body 201 is lower than two degrees, the programmable control chip controls the carbon steel anti-dry burning heating rod 206 to be energized to heat the water inside the water tank body 201. After heating to six degrees, multiple temperature sensors 205 detect that the temperature has reached the threshold and send a pulse signal to the programmable control chip. The programmable control chip then cuts off the power to the carbon steel anti-dry burning heating rod 206 and no longer heats the water inside the water tank body 201.

[0030] During use, the delivered water is stored in the quantitative water tank 2041. When flushing, the pressure water pump 2042 is started by the control box 3. The pressure water pump 2042 draws out the water inside the quantitative water tank 2041 and delivers it to the inside of the water spray seat 2044 through the connecting pipe 2043. The water is sprayed out through multiple leakage holes 2045 at the bottom and side of the water spray seat 2044. Since it is a straight-through type, a small amount of water can flush the excrement out of the toilet bowl 102.

[0031] During the flushing process, the water pressure pushes the silicone counterweight plate 1034 downward, causing the silicone counterweight plate 1034 to flip along the connection position between the silicone counterweight plate 1034 and the round tube 1033. After the water flushes down, the silicone counterweight plate 1034 is restored to its original state according to the recovery property of the silicone on the silicone counterweight plate 1034. There is no magnet or spring setting, which reduces the probability of equipment failure and prevents odor from overflowing.

[0032] A capacitive water level sensor is provided inside the water tank body 201 for intelligently monitoring the water level inside the water tank body 201. A leakage protector is connected in series with the circuit of the carbon steel anti-dry-burning heating rod 206 to increase the safety of the circuit and improve the safety of the equipment. These are all common technical means in smart toilets and will not be elaborated on here.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
