[0042] The present application describes a plurality of embodiments, but the description is exemplary rather than limiting, and it is obvious to those skilled in the art that there can be more embodiments and implementation schemes within the scope of the embodiments described in the present application.

[0044] Furthermore, in describing representative embodiments, the specification can have presented the method and / or process as a particular sequence of steps. However, to the extent that the method or process depends on more than one step, the method or process should not be limited to the particular sequence of steps described. Other sequences of steps can be possible, as would be understood by a person of ordinary skill in the art. Therefore, the particular order in which the steps are presented in the specification is not an indication of the order in which the steps are to be performed. Additionally, the claims set forth below are not to be limited by the particular order in which the steps are written.

[0045] Embodiments of the present application provide a toilet, such as Figures 3-7 In the illustrated embodiment, the toilet is a flip-type toilet bowl, which includes a toilet body 1 and a toilet bowl module 2. The toilet bowl module 2 includes a toilet bowl box 21 fixed relative to the toilet body 1 and a toilet bowl pipe 22 at least partially located in the toilet bowl box 21. The toilet bowl pipe 22 is connected to a toilet bowl outlet of the toilet body 1 and is configured to rotate about a central axis of the toilet bowl outlet relative to the toilet body 1 between an initial position and a toilet bowl position. When rotated to the toilet bowl position, the toilet bowl pipe 22 discharges waste toward a discharge opening of the toilet bowl box 21. The toilet further includes a control device, a water replenishing device, and a water level sensor 3. The water replenishing device and the water level sensor 3 are connected to the control device, and the water level sensor 3 is configured to detect a water level of a water seal surface of the toilet. The water replenishing device, the water level sensor 3, and other devices requiring power are connected to a power source, which can be a battery installed on the toilet or a household power supply.

[0046] The control device is configured to give an alarm prompt when the water seal surface water level meets a first condition, and to control the water supplement device to supplement water to the closestool main body 1 to make the water seal surface reach a normal water level when a second condition is met; the first condition is that the falling time t1 of the water seal surface from the normal water level to the excessively low water level under the condition that the closestool is not flushed does not exceed a first preset time T1, and the second condition is that the falling time t1 of the water seal surface from the normal water level to the excessively low water level under the condition that the closestool is not flushed exceeds the first preset time T1.

[0047] The normal water level is a water seal surface water level of the closestool in a normal state set for deodorization, and the excessively low water level is a preset water level lower than or equal to the normal water level. Figure 2 A water seal surface of a closestool in a normal water level A is shown in an embodiment, Figure 3 A water seal surface of a closestool in an excessively low water level lower than or equal to a preset water level B is shown, and the preset water level B has a preset water level difference from the normal water level A.

[0048] The technical scheme provided by the embodiment of the application can determine that the closestool is in an abnormal condition if the falling time t1 of the water seal surface from the normal water level to the excessively low water level under the condition that the closestool is not flushed does not exceed the first preset time T1. The abnormal condition can be, for example, that the sewage pipe of a flip-type sewage closestool cannot be reset due to being blocked by foreign matter, so that the water seal surface is in the excessively low water level, or that the closestool has other serious leakage conditions. An alarm is given when it is determined that the closestool is in an abnormal condition, so as to remind the user. The user can receive feedback and perform inspection and repair operations on the closestool. If the falling time t1 of the water seal surface from the normal water level to the excessively low water level is greater than the first preset time T1, it indicates that the closestool has slow leakage. The slow leakage can be caused by aging of a sealing connector, and the sealing connector that appears slow leakage is usually a sealing connector between the sewage box and the sewage outlet of the closestool main body 1. Since other sealing connectors can pollute the bathroom, it is not necessary to detect the water level to know that slow leakage occurs. In this case, the user can not process or urgently process the closestool. The closestool can automatically supplement water, so that the closestool can be automatically supplemented with water when the water level is detected to decrease from the normal water level to the excessively low water level under the condition that the closestool is not flushed, so as to solve the problem of deodorization caused by the excessively low water seal surface.

[0049] Therefore, the scheme provided by the embodiments of the present application can automatically determine the possible situation of the water seal surface being too low and take different measures according to different situations when the water seal fails due to the water seal surface being too low. In the case of rapid leakage of the toilet or other abnormal situations (for example, the sewage pipe of the flip-type sewage toilet is blocked by foreign matter and is not flipped into place), the user is warned, and the user can solve the toilet odor problem according to the feedback; in the case of slow leakage of the toilet, the control device can automatically supplement water to the toilet. Since the leakage is very slow, the entire device can be used for a long time even without maintenance. During use, the slow leakage of the toilet due to the sealing connector and other reasons causes the water seal surface to be too low, and the odor problem is solved by automatic water replenishment.

[0050] The scheme provided by the present application is suitable for a flip-type sewage toilet. Since the situation that the sewage pipe of the flip-type sewage toilet is blocked by foreign matter and is not flipped into place is relatively common, when the control device gives a warning, the user can check whether the sewage pipe of the toilet is not reset, so that the problem of the water seal surface being too low can be quickly solved.

[0051] In one embodiment, as shown in Figure 1 and Figure 2 , the control device is further configured to control the water replenishing device to replenish water to the toilet body when the information that the duration t2 of the water seal surface being at the low water level is greater than the second preset duration T2 is obtained for the first time, so that the water seal surface reaches at least the normal water level. The falling duration t1 is started to be counted after the water replenishing device replenishes water to the toilet body.

[0052] The information that the duration t2 of the water seal surface being at the low water level is greater than the second preset duration T2 is obtained for the first time means that the duration t2 of the water seal surface being at the low water level is greater than the second preset duration T2 has not occurred before. When it occurs for the first time, the falling duration of the water seal surface from the normal water level to the low water level is not detected, so in this case, the water replenishing device is controlled to replenish water to the toilet body. After the water level of the toilet body reaches the normal water level, the falling duration t1 of the water seal surface from the normal water level to the low water level is started to be counted, and then the abnormal situation of the water seal surface falling to the low water level is determined according to the falling duration t1.

[0053] In one embodiment, as shown in Figure 1 , the control device is configured to, after the falling duration t1 is started to be counted, if the falling duration t1 is within the first preset duration T1 (i.e., t1≤12h, Figure 1In the embodiment shown in FIG. 1, the control device is configured to, after starting timing the falling duration tl, determine whether the water level of the water seal surface is at the low water level within the first preset duration Tl (i.e., tl≤12h); if the water level of the water seal surface is at the low water level within the first preset duration Tl, determine whether the duration t2 of the water seal surface being at the low water level is greater than the second preset duration T2 (i.e., t2>30s); if the duration t2 of the water seal surface being at the low water level is greater than the second preset duration T2, determine that the water level of the water seal surface meets the first condition, and the control device determines that an abnormality occurs and prompts an alarm; if the duration t2 of the water seal surface being at the low water level is not greater than the second preset duration T2, determine that the falling of the water level of the water seal surface is caused by flushing the toilet, and re-time the falling duration tl; if the water level of the water seal surface is not at the low water level when the falling duration tl exceeds the first preset duration Tl (i.e., tl>12h), determine that the water level of the water seal surface meets the second condition, and control the water supplement device to supplement water to the toilet body 1 so that the water level of the water seal surface reaches the normal water level, and re-time the falling duration tl; if the toilet is flushed when the falling duration tl exceeds the first preset duration Tl, re-time the falling duration tl.

[0054] In another embodiment, as shown in FIG. 2, the control device is configured to, after starting timing the falling duration tl, determine whether the water level of the water seal surface is at the low water level within the first preset duration Tl (i.e., tl≤12h, t2>30s); if the water level of the water seal surface is at the low water level within the first preset duration Tl, determine that the water level of the water seal surface meets the first condition, and the control device determines that an abnormality occurs and prompts an alarm; if the water level of the water seal surface is not at the low water level when the falling duration tl exceeds the first preset duration Tl (i.e., tl>12h), determine that the water level of the water seal surface meets the second condition, and control the water supplement device to supplement water to the toilet body 1 so that the water level of the water seal surface reaches the normal water level, and re-time the falling duration tl; if the toilet is flushed when the falling duration tl exceeds the first preset duration Tl, re-time the falling duration tl. Figure 2 Figure 2 In the embodiment shown in FIG. 1, the control device is configured to, after starting timing the falling duration tl, determine whether the water level of the water seal surface is at the low water level within the first preset duration Tl (i.e., tl≤12h, t2>30s); if the water level of the water seal surface is at the low water level within the first preset duration Tl, determine that the water level of the water seal surface meets the first condition, and the control device determines that an abnormality occurs and prompts an alarm; if the water level of the water seal surface is not at the low water level when the falling duration tl exceeds the first preset duration Tl (i.e., tl>12h), determine that the water level of the water seal surface meets the second condition, and control the water supplement device to supplement water to the toilet body 1 so that the water level of the water seal surface reaches the normal water level, and re-time the falling duration tl; if the toilet is flushed when the falling duration tl exceeds the first preset duration Tl, re-time the falling duration tl. Figure 2

[0055] In one embodiment, as shown in FIG. 1, the toilet is a flushing toilet, and the water level sensor 3 is arranged on the toilet body 1, and is configured to detect the water level of the water seal surface of the toilet. Figures 3-7

[0056] ​​​The water level sensor 3 can be a contact water level sensor. The water level sensor 3 is installed on the side wall of the sewage pipe 22. A hole can be made in the side wall of the sewage pipe 22 so that the water level sensor 3 can detect the water level by contacting the water in the sewage pipe 22 through the hole. In other embodiments, the water level sensor 3 can also be inserted into the water from the top opening of the sewage pipe 22 to detect the water level.

[0057] The water level sensor 3 can also be a non-contact water level sensor. The non-contact sensor can be a laser liquid level sensor, a capacitive liquid level sensor, or a photoelectric liquid level sensor, etc. The non-contact water level sensor can be installed on the outside of the side wall of the sewage pipe 22 or on the sewage box 21.

[0058] Figure 6 The water level sensor 3 is shown to be installed on the outer side wall of the drain pipe 22 of the drain module 2. Figure 7 The image shows that the water level sensor 3 is installed on the sewage box 21 of the sewage module 2.

[0059] like Figure 7 As shown, the sewage box 21 includes a sewage box body 211 with an opening on one side and a sewage box cover 212 covering the opening on one side of the sewage box body 211. The sewage pipe 22 is installed into the sewage box 21 through the opening on one side of the sewage box body 211, and then the sewage box cover 212 is placed over the opening. A flipping power mechanism 23 is provided on the outside of the sewage box cover 212. This flipping power mechanism 23 is connected to the sewage pipe 22 through the sewage box cover 212 to drive the sewage pipe 22 to flip. In this example, the water level sensor 3 is a non-contact sensor and is located on the sewage box cover 212, but it can also be located on the sewage box body 211.

[0060] Since the sewage box 21 is located outside the sewage pipe 22, installing the water level sensor 3 on the sewage box 21 facilitates the exit of the connection wire of the water level sensor 3.

[0061] The control process when the toilet water cover fails is described below through two specific examples.

[0062] Example 1

[0063] refer to Figure 1, the water level sensor 3 detects the water seal water level, and when it is detected that the water seal is at an excessively low water level (for example, the water seal is lower than 30 mm) and the duration t2 of the water seal being at the excessively low water level is not greater than 30 s (the second preset duration T2 is set to 30 s), it is determined that the water seal being at the excessively low water level is caused by flushing the toilet, and the water seal can return to the normal water level within 30 s. If the duration t2 of the water seal being at the excessively low water level is greater than 30 s, it is determined that the water seal being at the excessively low water level is not caused by flushing the toilet, and the toilet has an abnormal condition such as rapid water leakage or slow water leakage. At this time, the water replenishing device is controlled to replenish water to the toilet main body 1 so that the water seal reaches the normal water level, and the falling duration t1 is started to be counted to further determine the abnormal condition of the toilet.

[0064] When the falling duration t1 is less than or equal to 12 h (i.e., t1 is within the first preset duration T1, and the first preset duration T1 is set to 12 hours), if there is a situation of flushing the toilet, the water level of the water seal is detected before flushing. If it is detected that the water level of the water seal is at an excessively low water level, it indicates that the water level of the water seal has fallen from the normal water level to the excessively low water level within the first preset duration T1, and the water level of the water seal satisfies the first condition. Therefore, the control device determines that there is an abnormality and gives an alarm. If the water level of the water seal is not detected to be at an excessively low water level, the falling duration t1 is restarted to be counted after flushing the toilet, i.e., the falling duration of the water seal from the normal water level to the excessively low water level is recalculated after flushing the toilet.

[0065] When the falling duration t1 is less than or equal to 12 h, if there is no situation of flushing the toilet, it is determined whether the water seal is at an excessively low water level when the falling duration t1 is not greater than 12 h. If the water seal is at an excessively low water level when the falling duration t1 is less than or equal to 12 h, the water seal satisfies the first condition, the control device determines that there is an abnormality and gives an alarm. If the water seal is detected to be at an excessively low water level when the falling duration t1 exceeds the first preset duration T1 without flushing the toilet, the water seal satisfies the second condition, and the water replenishing device is controlled to replenish water to the toilet main body 1 so that the water seal reaches the normal water level. The falling duration t1 is restarted to be counted. If the toilet is flushed when the falling duration t1 exceeds the first preset duration T1, the falling duration t1 is restarted to be counted.

[0066] Embodiment Two

[0067] Reference Figure 2, the water level sensor 3 detects the water seal water level, when detecting that the water seal is at an excessively low water level (for example, the water seal is lower than 30 mm), and the duration t2 of the water seal being at the excessively low water level is not greater than 30 s (the second preset duration T2 is set to 30 s), it is determined that the water seal being at the excessively low water level is caused by flushing the toilet, and the water seal can return to the normal water level within 30 s. If the duration t2 of the water seal being at the excessively low water level is greater than 30 s, it is determined that the water seal being at the excessively low water level is not caused by flushing the toilet, and the toilet has an abnormal condition such as rapid water leakage or slow water leakage. At this time, the water replenishing device is controlled to replenish water to the toilet main body 1 so that the water seal reaches the normal water level, and the falling duration t1 is started to be counted to further determine the abnormal condition of the toilet.

[0068] When the falling duration t1 is less than or equal to 12 h (that is, t1 is within the first preset duration T1, and the first preset duration T1 is set to 12 h), if the water seal is detected to be at an excessively low water level, it is determined whether the duration t2 of the water seal being at the excessively low water level is greater than 30 s (that is, whether the duration t2 of the water seal being at the excessively low water level is greater than the second preset duration T2), so as to determine whether the water seal being at the excessively low water level is caused by flushing the toilet. If the duration t2 is greater than 30 s, it is determined that the water seal water level satisfies the first condition, the control device determines that an abnormality occurs, and an alarm is prompted. If the duration t2 is not greater than 30 s, it is determined that the water seal being at the excessively low water level is caused by flushing the toilet, and the falling duration t1 is restarted to be counted.
