Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0036] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings:

[0037] refer to Figures 1 to 5According to the toilet body of the first embodiment of the present application, the main body 100 and the water flow component 200 include a main body 100 and a water flow component 200, the main body 100 includes a toilet chamber 110 and an installation chamber 120 arranged adjacent to each other in front and back, the toilet chamber 110 is located in front of the installation chamber 120, and a human body sensor 130 is further provided on the outer wall in front of the main body 100, and the water flow component 200 includes a water inlet 210, a first water outlet 220, a second water outlet 230, a first pipe 240, and a second pipe 250, a pump body 260 and a liquid storage member 270, the first water outlet 220 and the second water outlet 230 are both located at the upper end of the toilet chamber 110, the water inlet 210 is connected with the first water outlet 220 through a first pipe 240, the water inlet 210 is connected with the second water outlet 230 through a second pipe 250, the pump body 260 is located in the installation cavity 120, the liquid storage member 270 is connected with the second pipe 250 through the pump body 260, and the liquid storage member 270 is used to store cleaning agent. The human body sensor 130 is used to sense the human body within a set range. The human body sensor 130 is communicated with the pump body 260 through the controller 140. The controller 140 controls the pump body 260 to start according to the sensing signal transmitted by the human body sensor 130. The pump body 260 draws detergent from the liquid storage part 270 and injects it into the second pipe 250. The detergent is mixed with running water in the second pipe 250 and discharged from the second water outlet 230 to flush the inner wall of the toilet chamber 110, thereby achieving timely cleaning of the inner wall of the toilet chamber 110.

[0038] It should be noted that the first pipe 240 and the first water outlet 220 form a first water circuit, the second pipe 250 and the second water outlet 230 form a second water circuit, and the pump body 260 is used to transfer the detergent in the liquid storage part 270 to the second pipe 250, and the detergent is mixed with the water flow in the second pipe 250 and then sprayed out from the second water outlet 230. Among them, the first water circuit is provided with a larger water flow than the second water circuit, and the size of the water flow can be controlled by controlling the flow rate of water in the water circuit, the size of the diameter of the water circuit pipe, the opening degree of the valve connected to the water circuit, etc. The first water circuit is used to flush the toilet cavity, and the second water circuit is used to discharge the running water mixed with the detergent through the second water outlet 230 to clean the inner wall of the toilet cavity 110, so as to timely clean the pollutants such as urine scale remaining after flushing by the first water circuit, which is beneficial to ensure the cleanliness of the toilet.

[0039] Specifically, the first water path is used to flush the toilet bowl cavity 110. When the human body sensor 130 senses that the human body is away from the toilet, for example, the human body sensor 130 can be an infrared sensor. The use of infrared sensor detection signals to control the water flow interruption can be commonly seen in automatic sensing faucets, infrared smoke alarms, and pet drinking water equipment. The automatic sensing faucet can automatically turn on the water flow when a person's hand approaches, and automatically disconnect when the person leaves; the infrared smoke alarm can detect smoke particles in the air. When smoke particles are detected, the infrared smoke alarm transmits a signal to control the spraying of water for fire extinguishing; the pet drinking water equipment senses the pet through the infrared sensor, and automatically supplies water when a pet approaches. Based on this, the use of infrared sensors to control the water flow interruption is known to those skilled in the art based on existing control principles and control methods, and its specific control methods and control principles are not described in detail. The human body sensor 130 transmits a sensing signal to the controller 140, and the controller 140 controls the pump body 260 to start. The pump body 260 sucks the detergent in the liquid storage part 270 into the second pipe 250, and the detergent is mixed with the water flow in the second pipe 250. The second water outlet 230 sprays the water flow mixed with the detergent to clean the inner wall of the toilet bowl cavity 110, so as to promptly remove pollutants such as urine scale remaining on the toilet bowl cavity 110, and avoid the long-term accumulation of pollutants on the toilet.

[0040] It should be understood that the time for injecting water into the second pipe 250 through the water inlet 210 and the start time of the pump body 260 can be set. For example, water is first injected into the second pipe 250 through the water inlet 210. After the water injection starts, the pump body 260 is delayed to start pumping detergent into the second pipe 250. The pump body 260 is closed at a preset time. During the period when the pump body 260 is turned on, the water flow in the second pipe 250 always keeps flowing toward the second water outlet 230. After the pump body 260 is closed, the water flow in the second pipe 250 stops flowing with a delay, so as to avoid residual detergent in the second pipe 250, which is beneficial to prolonging the service life of the second pipe 250.

[0041] Artificial removal of urine scale usually uses highly corrosive cleaning agents such as disinfectants and toilet cleaners to dissolve urine scale. However, disinfectants and toilet cleaners are destructive to human skin and toilet materials. In addition, in order to quickly remove urine scale, there is also a situation where disinfectants and toilet cleaners are mixed for use. Among them, the main component of the disinfectant is sodium hypochlorite, and the main component of the toilet cleaner is hydrochloric acid. The mixture of the two will produce a chemical reaction to generate toxic gas chlorine, which is harmful to human health. The use of weak acid to dissolve urine scale is slow, the descaling efficiency is low, and the descaling is easy to remain. In some embodiments of the present application, the cleaning agent stored in the liquid storage part 270 can be selected from citric acid, picric acid and other aqueous solutions that do not contain chlorine elements, which is safer to remove pollutants such as urine scale. It should be understood that after the controller 140 receives the two signals transmitted by the human body sensor 130, that is, the human body enters the sensing range and the human body leaves the sensing range, the second water outlet 230 sprays the detergent mixture to remove scale. When the human body is within the sensing range of the human body sensor 130, the human body sensor 130 transmits a sensing signal to the controller 140, and the controller 140 limits the opening of the pump body 260. This ensures that the urine scale on the inner wall of the toilet chamber 110 is removed in time, and pollutants such as urine scale are prevented from precipitating and accumulating on the inner wall of the toilet chamber 110. At the same time, it also prevents the detergent mixture from splashing onto human skin, thereby achieving safe and timely descaling.

[0042] refer to Figures 1 to 5 In some embodiments, the toilet body further includes a heating assembly 300, which includes an infrared light source 310. The infrared light source 310 is installed at the upper end of the toilet bowl cavity 110. The infrared light source 310 emits infrared light waves toward the inside of the toilet bowl cavity 110 to heat and sterilize the inner wall of the toilet bowl cavity 110 and the water storage bay in the toilet bowl cavity 110. The infrared light source 310 is connected to the human body sensor 130 through the controller 140. The human body sensor 130 transmits sensing information to the controller 140. The controller 140 controls the switch of the infrared light source 310 according to the sensing information, so as to control the infrared light source 310 to turn on and heat and sterilize in time after the human body sensor 130 senses that the human body has left, which is beneficial to maintaining the hygiene of the toilet bowl cavity 110.

[0043] Specifically, before a person leaves the toilet, the first water path is used to flush the toilet. When the human body sensor 130 senses that the person has left the sensing range, the human body sensor 130 feeds back the sensing signal to the controller 140. The controller 140 controls the infrared light source 310 to turn on, and sterilizes and disinfects the toilet bowl cavity 110 by heating the toilet bowl cavity 110 with infrared rays. The infrared light source 310 can be set to turn on for a fixed time, and can also be set to turn off when the human body sensor 130 senses the person, so that the infrared light source 310 is turned off when the person approaches the human body sensor 130 to avoid infrared light damaging the skin of the person. To avoid inaccurate sensing caused by external environmental interference, during the process of turning on the infrared light source 310, the controller 140 can control the human body sensor 130 to narrow the sensing range, so as to ensure that the infrared light source 310 is turned off when the person is close to the human body sensor 130. After the infrared light source 310 is interrupted, in order to ensure that the temperature in the toilet bowl cavity 110 is appropriate, the first water path can flush water to reduce the temperature in the toilet bowl cavity 110, which is beneficial to ensure the comfort of using the toilet.

[0044] It should be noted that currently toilets mainly use electrolysis and UVC (short-wave ultraviolet light) for sterilization. The principle of electrolysis sterilization is to produce chlorine compounds through electrolysis of water for sterilization, which is greatly affected by the electrolysis time and the chlorine content in the water. During sterilization, it is easy to have a poor sterilization effect due to the short electrolysis time and insufficient chlorine content. However, the penetration ability of UVC is weak, and it is easily blocked by the residues on the inner wall surface of the toilet cavity 110 to form a sterilization dead corner. Compared with the two sterilization methods of electrolysis and UVC, infrared rays have a stronger penetration effect, and infrared rays sterilize the toilet cavity 110 by heating. The heat can be transferred along the inner wall of the toilet cavity 110 until the entire toilet cavity 110 is heated, effectively eliminating the sterilization dead corner. At the same time, high temperature also helps to promote the mixed liquid of detergent and water to dissolve urine scale and improve the removal efficiency.

[0045] refer to Figures 1 to 5 In some embodiments, the heating assembly 300 further includes a temperature sensor 320, which is located at the upper end of the toilet bowl cavity 110. The temperature sensor 320 is connected to the infrared light source 310 through the controller 140. The temperature sensor 320 is used to detect the temperature information in the toilet bowl cavity 110 and transmit the temperature information to the controller 140. The controller 140 controls the infrared light source 310 to be turned off according to the detected temperature information. Alternatively, the temperature sensor 320 is connected to the pump body 260 through the controller 140 and transmits the temperature information to the controller 140. The controller 140 controls the pump body 260 to be turned on according to the temperature information. Timely high-temperature sterilization or descaling is achieved.

[0046] In other embodiments, the temperature sensor 320 is used to detect temperature information in the toilet bowl cavity 110 and transmit the temperature information to the controller 140. The controller 140 controls the closing of the infrared light source 310 according to the detected temperature information. In addition, the temperature sensor 320 is also communicated with the pump body 260 through the controller 140 and transmits the temperature information to the controller 140. The controller 140 controls the opening of the pump body 260 according to the temperature information. Specifically, after the human body sensor 130 senses that the human body has left the sensing range, the human body sensor 130 is connected to the infrared light source 310 through the controller 140, and the controller 140 controls the opening of the infrared light source 310, and the infrared light source 310 heats and sterilizes the toilet cavity 110. When the temperature sensor 320 detects that the temperature in the toilet cavity 110 reaches a preset temperature value, the temperature information is fed back to the controller 140, and the infrared light source 310 is turned off through the controller 140. After the infrared light source 310 is turned off, the temperature in the toilet cavity 110 slowly drops, and the sterilization of the inside of the toilet cavity 110 can still be maintained for a certain period of time.

[0047] In other embodiments, after the human body sensor 130 senses that the human body has left the sensing range for a certain period of time, the infrared light source 310 is turned on to heat and sterilize the toilet bowl cavity 110, and the temperature sensor 320 senses the temperature inside the toilet bowl cavity 110. When the temperature of the toilet bowl cavity 110 reaches a preset temperature value, the temperature sensor 320 transmits temperature information to the controller 140, and the controller 140 controls the pump body 260 to turn on. The pump body 260 draws detergent from the liquid storage part 270 and injects it into the second pipe 250, so that the detergent is mixed with water in the second pipe 250, and the aqueous solution mixed with the detergent flows out from the second water outlet 230 to descale the toilet bowl cavity 110. After the second water outlet 230 stops discharging water, the infrared light source 310 remains on for a period of time and then turns off. The detergent has a better cleaning effect at high temperature, further ensuring the cleanliness of the toilet.

[0048] It should be noted that the preset temperature values ​​at the above-mentioned locations can be adjusted to different values ​​according to needs. When the toilet is performing the above-mentioned actions, the human body sensor 130 always senses the surrounding human bodies. When a human body is detected approaching the toilet, the human body sensor 130 immediately transmits the sensing information to the controller 140. The controller 140 controls the infrared light source 310 to turn off, and the first water outlet 220 discharges water to flush the inside of the toilet bowl cavity 110 to reduce the temperature inside the toilet bowl cavity 110. The flushing time can be set according to needs to ensure the normal use of the toilet.

[0049] Alternatively, when the temperature sensor 320 detects that the temperature inside the toilet chamber 110 reaches a preset temperature value, the temperature sensor 320 transmits the temperature information to the controller 140, and the controller 140 controls the infrared light source 310 to disconnect, and opens the water valve corresponding to the first water channel, and the first water outlet 220 drains water to reduce the temperature inside the toilet chamber 110. Similarly, the water valve of the first water channel is closed after being opened for a set time, and the first water outlet 220 also stops draining water after discharging water for a period of time.

[0050] refer to Figures 1 to 5 In some embodiments, the heating component 300 includes a temperature sensor 320 and an infrared light source 310. The temperature sensor 320 is arranged adjacent to the infrared light source 310. The heating component 300 is located on the side of the toilet chamber 110 close to the installation chamber 120. A device for supplying power to the heating component 300 is provided in the installation chamber 120. Therefore, the heating component 300 is arranged on the side of the toilet chamber 110 close to the installation chamber 120, which can effectively shorten the wiring length of the heating component 300 and facilitate installation.

[0051] refer to Figures 1 to 5 In some embodiments, the water flow component 200 further includes a water distribution member 280, on which a water inlet 210 and a plurality of water distribution ports 281 are provided, the first pipe 240 and the second pipe 250 are respectively connected to different water distribution ports 281, the human body sensor 130 is communicated with the water distribution member 280 through the controller 140, each water distribution port 281 is provided with a water valve, each water valve can be individually controlled to be on and off, the human body sensor 130 is used to transmit a sensing signal to the controller 140, and the controller 140 controls the sensing signal according to the sensing signal. The signal controls the opening of the water supply valve of the water outlet 281 on the water distribution member 280, so that the water entering the water distribution member 280 from the water inlet 210 can flow out from one of the water outlets 281 alone, wherein the first pipe 240 and the first water outlet 220 as the first water path can flow through a larger water flow, the first water path is used for flushing and cooling, the second pipe 250 and the second water outlet 230 as the second water path can flow through a smaller water flow, the second water path is used to spray an aqueous solution containing a detergent to remove pollutants such as urine scale remaining in the toilet bowl cavity.

[0052] refer to Figures 1 to 5 In some embodiments, the water flow component 200 also includes a third pipe 290, and the liquid storage component 270 is connected to the pump body 260 through the third pipe 290. The liquid storage component 270 is located outside the installation cavity 120 and can be placed on one side of the toilet. Compared with the liquid storage component 270 being set in the installation cavity 120, the liquid storage component 270 being set outside the installation cavity 120 facilitates the addition of detergent into the liquid storage component 270, thereby ensuring the normal operation of the toilet descaling function.

[0053] refer to Figures 1 to 4In some embodiments, an annular groove 111 is provided at the opening of the upper end of the toilet cavity 110, and the opening of the annular groove 111 is arranged toward the toilet cavity 110. The first water outlet 220 is located in the annular groove 111, and the first water outlet 220 is used to discharge water into the annular groove 111, so that the water flows along the annular groove 111, and the water will flow from the opening of the annular groove 111 into the toilet cavity 110 during the process of flowing in the annular groove 111, and flow downward along the inner wall of the toilet cavity 110, forming a rotating water flow in the toilet cavity 110, thereby improving the cleaning ability of the toilet cavity 110.

[0054] refer to Figures 1 to 4 In some embodiments, the inner wall of the annular groove 111 is connected to the inner wall of the toilet chamber 110. The annular groove 111 includes a starting end 1111 and a terminal end 1112 near the installation chamber 120. Along the extension direction from the starting end 1111 to the terminal end 1112, the change trend of the cross-sectional area of ​​the annular groove 111 is configured to gradually decrease first, then gradually increase, and finally gradually decrease again. The first water outlet 220 is located at the starting end 1111. The first water outlet 220 is arranged toward the front. The water flowing out of the first water outlet 220 flows along the annular groove 111 and flows out of the annular groove 111 during the flow. The water flows along the inner wall of the toilet chamber 110 to flush the toilet chamber 110. It should be noted that the curvature of the annular groove 111 is different at different places. On the side of the toilet chamber 110 away from the installation chamber 120, the curvature of the annular groove 111 is larger. When the water flows to this section, it will be subjected to a greater centrifugal force than other sections, and the water is not easy to flow out of the annular groove 111. Therefore, the cross-sectional area of ​​this section of the annular groove 111 is smaller, so that the bearing area of ​​the annular groove 111 for the water flow in this section is smaller, which facilitates the water flow to escape from the annular groove 111 and flush the inner wall of the toilet chamber 110, that is, the cross-sectional area of ​​the annular groove 111 gradually decreases from the starting end 1111 to this section, and its curvature gradually decreases from this section to the terminal end 1112, and the cross-sectional area of ​​the annular groove 111 in this section gradually increases to better carry the circular flow of water and fully flush the inner walls of the toilet chamber 110. Along the extension direction of the annular groove 111, the cross-sectional area at the terminal end 1112 of the annular groove 111 gradually decreases, which is used to speed up the water flow speed and form a rotating water flow, which is beneficial to improving the flushing effect.

[0055] refer to Figure 1 In some embodiments, the second water outlet 230 is located on a side of the toilet chamber 110 close to the installation chamber 120. Compared with being set at other positions of the toilet chamber 110, it is beneficial to shorten the length of the second pipe 250. The second water outlet 230 is also connected to a nozzle 231, which is used to spray water mixed with a detergent. The use of the nozzle 231 can increase the coverage of the detergent, so that the cleaning liquid can better cover the inner wall of the toilet chamber 110, which is beneficial to reduce the amount of detergent used.

[0056] refer to Figures 1 to 5 According to the second aspect of the present application, the toilet comprises a water supply component, a toilet cover assembly and a toilet body in any of the above embodiments, the water supply component is connected to the water inlet 210, the toilet cover assembly comprises a seat ring and a toilet cover, and the seat ring and the toilet cover are both rotatably connected to the top of the toilet body.

[0057] In some embodiments, the toilet includes the toilet body in any of the above embodiments, the water supply part is connected to the water inlet 210 on the water distribution part 280, and the water distribution part 280 is also provided with multiple water distribution ports 281. The first pipe 240 and the second pipe 250 are connected to different water distribution ports 281. When the human body sensor 130 senses that the human body has left within the set range, the human body sensor 130 transmits a sensing signal to the controller 140, and the controller 140 controls the infrared light source 310 to turn on and heat and sterilize the toilet bowl cavity 110. The temperature sensor 320 is used to sense the temperature in the toilet bowl cavity 110. When the temperature in the toilet bowl cavity 110 reaches a preset temperature value, the temperature sensor 320 transmits temperature information to the controller 140. The controller 140 controls the infrared light source 310 to turn off according to the temperature information. The temperature in the toilet bowl cavity 110 is gradually reduced, so the high temperature sterilization effect can be maintained for a period of time.

[0058] After the infrared light source 310 is turned off for a period of time, if the human body sensor 130 does not sense that a human body enters the sensing range during the period when the infrared light source 310 is turned off, the infrared light source 310 is turned on to heat the toilet chamber 110, and the temperature sensor 320 detects the temperature in the toilet chamber 110. When the temperature in the toilet chamber 110 reaches a preset temperature value, the temperature sensor 320 transmits the detected temperature information to the controller 140, and the controller 140 controls the water valve of the water outlet 281 on the water distribution member 280 that is connected to the second pipe 250 to open, so that water flows into the second pipe 250. The controller 140 also controls The pump body 260 is opened later than the water valve, and the pump body 260 pumps the detergent in the liquid storage part 270 into the second pipe 250 to mix with the water flow. The water flow mixed with the detergent is sprayed out from the second water outlet 230. The mixed liquid is used to dissolve pollutants such as urine scale remaining on the inner wall of the toilet chamber 110 to avoid the accumulation of urine scale on the inner wall of the toilet chamber 110. The water valve on the water distribution part 280 is closed later than the pump body 260, so that the water flow in the second pipe 250 can discharge all the detergent pumped into the second pipe 250, avoid the detergent remaining in the second pipe 250, and help to extend the service life of the second pipe 250.

[0059] When the second water outlet 230 sprays water mixed with detergent, the infrared light source 310 always remains on to continuously heat the toilet bowl cavity 110. The detergent can dissolve urine scale faster when heated, which is beneficial to timely and efficient cleaning of the toilet.

[0060] In addition, when the infrared light source 310 is turned on, if the human body sensor 130 senses that a human body is approaching the toilet, the human body sensor 130 transmits a use signal to the controller 140, and the controller 140 controls the infrared light source 310 to be disconnected, and flushes and cools the toilet chamber 110 through the first water channel. The water flow rate and flow time of the first pipe 240 can be set.

[0061] The toilet in the embodiment of the present application is described below in combination with specific usage scenarios:

[0062] The human body sensor 130 may be an infrared sensor. The human body sensor 130 is always in an on state. When a human body is within the sensing range or outside the sensing range, the human body sensor 130 may transmit a corresponding sensing signal to the controller 140. When the human body sensor 130 cannot sense the presence of a human body for a long time, the toilet is in an idle state. The toilet does not perform any operation in the idle state. After the human body sensor 130 senses that a human body has entered the sensing range, it transmits a sensing signal to the controller 140. After the human body sensor 130 senses that a human body has left the sensing range, it transmits a sensing signal to the controller 140 again. After receiving the above two signals, the controller 140 controls the toilet. The component obtains from the water distribution component 280 whether the water valve connected to the first pipe 240 is closed, that is, determines whether the flushing is completed. After the flushing is completed, the water distribution component 280 transmits a signal that the water valve is closed to the controller 140, and the controller 140 controls the infrared light source 310 to turn on to sterilize the inner wall of the toilet cavity 110. At the same time, the temperature sensor senses the temperature in the toilet cavity 110. When the temperature sensor 320 senses that the temperature of the toilet cavity 110 reaches the set temperature, the temperature sensor 320 transmits a signal to the controller 140, and the controller 140 controls the infrared light source 310 to turn off, and the temperature in the toilet cavity 110 slowly drops, so that the toilet cavity 110 can be continuously sterilized within a certain period of time.

[0063] After the infrared sterilization process is completed, the controller 140 starts timing. After the timing reaches a preset time, the controller 140 controls the infrared light source 310 to turn on again, and the temperature sensor 320 senses the temperature of the toilet chamber 110. When the temperature of the toilet chamber 110 reaches the preset temperature value, the temperature sensor 320 transmits a sensing signal to the controller 140. After receiving the sensing signal, the controller 140 controls the water valve connected to the second pipe 250 on the water distribution member 280 to open, and delays the control of the pump body 260 to open. The pump body 260 is closed after the preset time is opened. The pump body 260 is used to transport cleaning agent from the liquid storage member 270 to the second pipe 250. The water valve connected to the second pipe 250 on the water distribution member 280 is delayed to close relative to the pump body 260, and the infrared light source 310 is delayed to close relative to the water valve connected to the second pipe 250 on the water distribution member 280. It should be noted that the preset temperature value in this step may be different from the preset temperature value in the previous step. The main purpose of this step is to remove scale. Therefore, the preset temperature value in this step can be set to a lower preset temperature value relative to the sterilization step to speed up the speed at which the detergent dissolves urine scale.

[0064] In the above two steps, the human sensor 130 and the temperature sensor 320 are always in the on state. When the human sensor 130 senses the human body, it will transmit a sensing signal to the controller 140. The controller 140 will interrupt other execution processes, control the infrared light source 310 to turn off, and control the water valve on the water distribution part 280 connected to the first pipe 240 to open, and flush and cool according to the preset water flow rate; or, when the temperature sensor 320 senses the preset upper temperature limit, the temperature sensor 320 transmits a sensing signal to the controller 140, and the controller 140 will also interrupt other execution processes, control the infrared light source 310 to turn off, and control the water valve on the water distribution part 280 connected to the first pipe 240 to open, and flush and cool according to the preset water flow rate. The above two interruption situations have higher priority than the sterilization and descaling steps. The water valve connected to the first pipe 240 stops after opening for a preset time to ensure the normal use of the toilet.

[0065] It should be noted that the controller 140 is a feedback loop component widely used in industrial control applications, such as a programmable memory, which generally stores instructions for performing operations such as logical operations, sequential control, timing, counting and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog input and output. The embodiment of the present application controls the on-off of the valves on the infrared light source 310, the pump body 260 and the water distribution member 280 through the controller 140 to achieve the mutual cooperation of flushing the first water channel and descaling the second water channel, as well as the sterilization of the infrared light source 310. This can be achieved by those skilled in the art based on the existing functions of the controller 140, and its control principle and control method are not described in detail here.

[0066] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
