[0046] The following will be described in detail below with reference to the accompanying drawings. Figure 1 - The accompanying drawings Figure 6 The present application will be further described in detail.

[0047] The present application discloses a toilet and a method for using the same.

[0048] A toilet, referring to Figure 1 and Figure 2 , comprises a toilet seat 1, a toilet cover 2, and a toilet ring 3; the toilet cover 2 and the toilet ring 3 are hinged to the toilet seat 1, and the toilet cover 2 covers the toilet ring 3; a flushing cavity 11 and a water storage cavity 12 are formed in the toilet seat 1, and the flushing cavity 11 is communicated with the water storage cavity 12, and the water storage cavity 12 is connected with a drain pipe.

[0049] The toilet seat 1 is in the shape of an elliptical cylinder, and the material can be ceramic; the flushing cavity 11 inside the toilet seat 1 is used for storing filth and water; the water storage cavity 12 is curved, and is used for forming a water seal with the flushing cavity 11 to avoid the odor of the external drain pipe entering the toilet seat 1; the toilet seat 1 can be a floor-mounted toilet seat 1 or a suspended toilet seat 1; taking the suspended toilet seat 1 as an example, the suspended toilet seat 1 refers to the toilet seat 1 directly installed on a wall, so that the toilet is suspended and not installed on the ground; therefore, the curvature of the water storage cavity 12 is changed accordingly.

[0050] The shape of the toilet ring 3 matches the cavity opening of the flushing cavity 11, and the size is slightly larger than the cavity opening of the flushing cavity 11, so that the toilet ring 3 can be placed on the wall surface of the toilet seat 1 outside the flushing cavity 11, and the user can sit on the toilet ring 3 when using, so as to separate the lower body of the user from the toilet seat 1 and keep the lower body of the user clean.

[0051] The shape of the toilet cover 2 is consistent with that of the toilet ring 3, and the size is slightly larger than that of the toilet ring 3, which is used for covering the toilet ring 3 and the flushing cavity 11 to avoid the odor in the toilet seat 1 from being transmitted out.

[0052] The toilet further comprises a water storage member 4, a water outlet member 5, and a discharge member 6; the water storage member 4 for storing flushing water is embedded in the toilet seat 1, and is connected with a water inlet pipe; the water storage member 4 can be a water storage tank or a water storage cavity formed directly in the toilet seat 1; in this embodiment, the water storage tank is taken as an example; after the external drain pipe is communicated with the water storage tank, the water storage tank can be supplied with water; the material of the water storage tank can be ceramic; a detachable cover is arranged on the water storage member 4, which is convenient for maintenance.

[0053] The water outlet 5 is embedded in the toilet seat 1 and has an inlet and an outlet. The outlet is located at the opening of the flushing chamber 11. The inlet is connected to the water storage component 4. The water outlet 5 can be a water outlet ring. The inlet of the water outlet ring is the water inlet and the outlet is the water outlet. There can be one or several water outlets, depending on the size of the toilet seat 1 and the size of the water outlet. The inlet is close to the bottom of the water storage tank.

[0054] The discharge device 6, which provides negative pressure water flow to the water storage component 4, is connected to the inner wall of the water storage component 4. The water storage component 4 can be a pressure cylinder, such as a small air cylinder or a small hydraulic cylinder. The output end of the pressure cylinder is equipped with a pressure cover. The pressure cover fits the inner wall of the water storage tank, that is, the two are matched in size. The pressure cover covers the water storage tank. The pressure cover can be a rubber cover. The outer surface of the pressure cylinder is also equipped with a sealing box. The output end of the pressure cylinder extends out of the sealing box to prevent the pressure cylinder from being stuck by water. The output end of the pressure cylinder can drive the pressure cover to move along the water storage tank. The output end of the pressure cylinder can be connected to an external switch outside the toilet seat 1 to control the opening and closing of the pressure cylinder.

[0055] Specifically, when the toilet seat 1 needs to be used, the user discharges excrement into the flushing chamber 11, and then opens the pressure cylinder by switching on a switch. The output end of the pressure cylinder drives the pressure cover to move along the water storage tank, causing the water in the storage tank to be pressurized by the pressure cover, rushing into the inlet of the water outlet ring, flowing along the inside of the water outlet ring, and being discharged from the outlet. The pressure provided by the pressure cover causes changes in water pressure to ensure that the water flow discharged from the outlet has sufficient flushing force to wash away the waste. When there is too much water in the flushing chamber 11, the waste... Water will flow into the water storage chamber 12 and be discharged from the water storage chamber 12 into the drain pipe to complete the discharge. The remaining water will form a water seal in the water storage chamber 12 to prevent odors from the drain pipe from coming out of the water storage chamber 12 and the flushing chamber 11. The pressurization of the pressurization cylinder ensures that there is enough flushing potential energy to flush away the dirt. Therefore, the water storage tank does not need to be installed at an external high place to maintain flushing potential energy. It can be directly installed in the toilet seat 1, reducing the overall space occupied. At the same time, the pressurization cylinder provides pressurization to ensure sufficient water pressure.

[0056] In some embodiments, refer to Figure 3 As shown, the water storage component 4 is provided with several baffles 44, and each baffle 44 has a preset opening for water flow. When the water storage component 4 is a water storage tank or water storage pool, the baffles 44 divide the space inside the water storage tank into several parts. In this embodiment, two baffles 44 are used as an example. The two baffles 44 cooperate with the wall of the water storage tank to divide the internal space of the water storage tank into three spaces. When the discharge component 6 is a small hydraulic cylinder, a small hydraulic cylinder is set in each of the three spaces.

[0057] The single small hydraulic cylinder can reduce the pressure application area, that is, when water is used, only the water in the single space separated by the water plate 44 is pressed down to reduce the amount of water used. When a user urinates, there is no need to use too much water and too high water pressure for flushing, so only one small hydraulic cylinder output end pressing down the pressure cover can apply negative pressure to the water for flushing. After the user defecates, three small hydraulic cylinders can be used to increase the negative pressure value and improve the flushing force. The water in the three spaces can also fully flush the excrement.

[0058] Specifically, the control switch can be provided with a urination flushing switch, a defecation flushing switch, and a child defecation flushing switch to control the required flushing amount in sequence. For example, the urination flushing switch only controls one small hydraulic cylinder for flushing, the child defecation flushing switch controls two small hydraulic cylinders for flushing, and the defecation flushing switch controls three small hydraulic cylinders for flushing to correspond to the required amount of water respectively, thereby achieving the effect of saving water.

[0059] In another embodiment, referring to FIG. 4, Figure 4 The water storage part 4 includes a water storage part 41, a sensing part 42, and a switch part 43. The water storage part 41 can be a water storage tank or a water storage pool. In this embodiment, the water storage tank is taken as an example. The water storage tank can be made of ceramic or plastic. The sensing part 42 and the switch part 43 are installed in the water storage tank and are electrically connected. The sensing part 42 can be a liquid level sensor, and the switch part 43 can be an electronic valve. The liquid level sensor is arranged inside the water storage tank and is close to the top of the water storage tank. The liquid level sensor is used to detect the water level in the water storage tank to determine whether the water needs to be supplemented. The electronic valve is connected with an external water inlet pipe. The valve body can open or close the water inlet pipe to control the water delivery of the water inlet pipe.

[0060] Specifically, when the liquid level sensor detects that the water in the water storage tank is insufficient, the electronic valve opens the water inlet pipe, and the water inlet pipe continuously delivers water to the water storage tank until the liquid level sensor detects that the water level is qualified, that is, the water in the water storage tank is sufficient. Then, a command is sent to the electronic valve to close the valve, thereby achieving the effect of automatically adding water.

[0061] In some embodiments, referring to FIG. 5, Figure 5 The water outlet part 5 includes a water outlet part 51, a reset part 52, and an adjusting part 53. The water outlet part 51 is internally provided with a water delivery cavity 54. One cavity opening of the water delivery cavity 54 is communicated with the water storage part 4, and the other cavity opening is communicated with the flushing cavity 11. The water storage part 4 is a water storage tank, and the water outlet part 51 is a water outlet cylinder. The water outlet cylinder is embedded in the toilet seat 1 and is close to the cavity opening of the flushing cavity 11. The water outlet cylinder is provided with one water inlet and one water outlet corresponding to the two cavity openings of the water delivery cavity 54. The water inlet is communicated with the water storage tank, and the water outlet is communicated with the flushing cavity 11. The water outlet cylinder is used to deliver and discharge the water in the water storage tank.

[0062] The adjusting part 53 is slidably located in the water delivery cavity 54 and blocks the cavity opening away from the water storage part 4. The adjusting part 53 can be an adjusting column. When the adjusting column moves along the water delivery cavity 54, the water outlet can be blocked or opened. The shape and size of the adjusting column are matched with the inner cavity space of the water delivery cavity 54, so that the blocking of the water outlet is stable and the gap is reduced.

[0063] The reset part 52 is located in the water delivery cavity 54 and connected with the adjusting column at one end and the inner wall of the water outlet cylinder at the other end. The reset part 52 can be a spring. The spring exerts force on the adjusting column, so that the adjusting column can move along the water delivery cavity 54 to achieve the reset effect.

[0064] When the water storage tank is affected by the discharge part 6 to form negative pressure, the water in the water storage tank flows into the water delivery cavity 54 affected by the negative pressure, and the water pressure can be adjusted according to the discharge part 6. The water flows into the water delivery cavity 54, and the adjusting column is affected by the water pressure and moves along the water delivery cavity 54 in the direction of the water pressure (refer to the change state shown in the figure). When the adjusting column is separated from the water outlet, the water outlet is opened to make the water flow from the water outlet to the flushing cavity 11, and the water flow and flow rate change with the size of the water pressure. When the flushing is completed, the pressure of the water flow on the adjusting column is less than the spring force on the adjusting column, so that the spring resets the adjusting column to move in the direction opposite to the direction of the water pressure, so as to block the water outlet and push the remaining water back into the water storage tank to reduce the loss of water and achieve the effect of water saving. Figure 5

[0065] The adjusting part 53 is wedge-shaped and gradually opens the cavity opening of the water delivery cavity 54 away from the water storage part 4 when sliding along the water delivery cavity 54, that is, the plane of the adjusting column towards the water outlet is wedge-shaped. When the adjusting column is affected by the water pressure, the adjusting column moves in the direction of the water pressure. During the movement, the water outlet is gradually opened by the wedge-shaped surface. The gradually opened water outlet can allow a small amount of water flow to enter the flushing cavity 11 first to wet the inner wall of the flushing cavity 11, and then flush out a larger water flow to discharge the dirt. Finally, when the spring is reset, the wedge-shaped surface of the adjusting column gradually moves in the direction opposite to the water pressure, so that the water outlet is gradually covered by the wedge-shaped surface to achieve the effect of gradually closing the water outlet. In this way, the remaining part of the water flow can enter the flushing cavity 11 from the water outlet. This part of the water can supplement and maintain the water storage capacity of the water seal.

[0066] ​The outlet of the water outlet 51 has an inclined wall, which is connected to the wall of the inner cavity of the flushing chamber 11. When water flows from the water storage tank into the water outlet, the water flows along the inclined wall of the outlet to guide the flow. The water flows along the inner wall of the flushing chamber 11 after it sprays from the outlet, thus guiding the water flow to the entire flushing chamber 11. In particular, the inner cavity of the flushing chamber 11 is elliptical, which allows the water flow to form a vortex along the inner cavity of the flushing chamber 11, thereby improving the flushing efficiency.

[0067] In some embodiments, the discharge component 6 includes a drain section 61 and a pressing section 62; the water storage component 4 is connected to the water outlet component 5 through the drain section 61, and the drain section 61 provides negative pressure. The water storage component 4 is a water storage tank, and the drain section 61 can be a small water pump. The pumping end of the small water pump can be a flexible hose connected to the bottom of the water storage tank, and the water delivery end can be directly connected to the water outlet component 5, such as directly connected to the inlet of the water delivery chamber 54, or a water delivery pipe can be provided to deliver water to the water delivery chamber 54.

[0068] The pressing part 62 is electrically connected to the drain part 61, and the input end of the pressing part 62 is located on the outer wall of the toilet seat 1. The pressing part 62 may include a pressing switch and a control board. The pressing switch is located outside the toilet seat 1, and the control board is embedded in the outer wall of the toilet seat 1. It may also be installed overlapping the pressing switch. The pressing switch is controlled by the control board. The small water pump inside the toilet seat 1 is also controlled by the control board signal.

[0069] Specifically, when the toilet needs to be used, the control board receives an activation signal by touching the button, which then controls the small water pump to pump water. During the pumping process, the control board can preset the pumping power of the small water pump and the continuous pumping time, and accurately control the pumping volume based on the pumping power and continuous pumping time.

[0070] In some embodiments, refer to Figure 6 As shown, the toilet seat 1 has a connection port 13; the water storage component 4 is directly connected to the flushing chamber 11 through the connection port 13. The water storage component 4 is a water storage tank. The connection port 13 is located on the side wall of the water storage tank near the top, and this side wall is close to the flushing chamber 11. Therefore, the connection port 13 can be directly connected to the flushing chamber 11. When there is a power outage, the water in the water storage tank will overflow. The overflowing water will directly overflow the toilet seat 1, causing damage to the driving components such as the small water pump, or filling the space where the toilet is installed with water, such as inside the toilet. Therefore, when the water overflows, it can be directly poured back into the flushing chamber 11 through the connection port 13 to avoid affecting the small water pump and the installation space of the toilet.

[0071] In some embodiments, the toilet seat 1 is also provided with a backup power supply 7, which can adopt a storage battery, and can be arranged inside the toilet seat 1 or on the wall of the toilet seat 1, for providing power supply for the power elements such as the discharge element 6 in the case of power failure or other special conditions.

[0072] A toilet using method based on a toilet, comprising the following steps:

[0073] S1, water storage: when the water level of the water storage element 4 is lower than the preset value, the water inlet pipe injects water into the water storage element 4, and when the preset value is reached, the water injection of the water inlet pipe is stopped.

[0074] Specifically, the liquid level sensor in the water storage element 4 senses whether the water level reaches the preset water level, and the electronic valve opens the water inlet pipe for water injection. When the liquid level sensor detects that the water level reaches the preset water level, it sends data information to the control panel of the discharge element 6, and the control panel sends a command to close the water inlet pipe to the electronic valve. The electronic valve receives the command and closes the water inlet pipe to stop water injection.

[0075] S2, water outlet: a flushing command is applied to the discharge element 6, and the discharge element 6 operates to form a negative pressure in the water storage tank to transport water to the water outlet element 5, and the water outlet element 5 realizes discharge.

[0076] Specifically, the user touches the press switch, the press switch sends a trigger information to the control panel, the control panel receives the trigger information and sends an opening command to the small water pump, and the small water pump receives the opening command and pumps water to the water storage tank, forming a negative pressure in the water storage tank, and pumping water to the water delivery cavity 54 of the water outlet cylinder until it is discharged from the water outlet.

[0077] P1, P3, and P2 are the negative pressure values that the control panel pre-sets for the water pumping of the small water pump, and their respective durations, the negative pressure values of P1, P2, and P3 are related to the water discharge amount delivered within the duration, so the duration of each negative pressure value can be consistent, or different durations can be adjusted according to the required water discharge amount.

[0078] S21, first stage: when the negative pressure value provided by the small water pump reaches P1, the water flow enters the flushing cavity 11 from the water outlet element 5 and flows along the inner wall surface of the flushing cavity 11, wetting the inner wall surface of the flushing cavity 11.

[0079] S22, second stage: after P1 lasts for a preset time, the negative pressure value provided by the discharge element 6 reaches P2, the water flow increases sharply, and the water flow potential for flushing the dirt increases to flush the dirt from the storage cavity 12 into the external drain pipe;
