[0002] As people's living standards continue to improve, smart homes and smart bathrooms are also developing and improving in a healthier and smarter direction. There is a large market demand for adding urine testing functions to smart toilets.

[0003] The existing urine test device is placed at the bottom of the toilet. When a urine test is required, the water seal at the bottom of the toilet seat must be emptied before the urine test can be performed. Furthermore, the urine test process requires the user to urinate as quickly as possible and leave in time, otherwise the test paper cannot be tested because the liquid level in the ceramic is higher than the test paper extension hole. The user experience is not good, and because of the influence of the water seal water on the test paper, the test paper reaction time is too long, resulting in unstable test results. Therefore, it is particularly important to change the influence of the water seal water on urine testing while retaining the daily water seal and odor isolation needs of the water seal water.

DETAILED DESCRIPTION

[0034] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0035] In the related art, the ceramic toilet seat has an inner cavity in the front wall or the rear wall of the toilet bowl, and the urine test device is arranged in the inner cavity. In order to facilitate urine collection, it is common to place the urine test device close to the sewage outlet at the bottom of the ceramic toilet seat to ensure that urine can be collected. However, if the urine test device is set at this position, it is inevitable that the water seal liquid level will be higher than the urine test device under normal conditions. If the water in the water seal is not emptied during the urine test, there will be no way to perform the test. Currently, the water seal water is usually emptied through normal drainage, but this method will quickly replenish the water seal water, requiring users to urinate quickly and test, which gives customers a poor experience and unstable test results.

[0036] See also Figures 1 to 9 A toilet 100 includes a toilet seat 10, a sewage pipe 30, a urine testing device 20 and a driving device. The toilet seat 10 includes a water seal groove 11, a sewage outlet 13 and a detection hole 12, and the sewage outlet 13 and the detection hole 12 are respectively arranged on the side wall of the water seal groove 11. The sewage pipe 30 includes an inlet end 31 and an outlet end 32, and the inlet end 31 is connected to the sewage outlet 13. The driving device and the urine testing device 20 are placed in the toilet 100, and the driving device is used to drive the sewage pipe 30 and / or related accessories matching the sewage pipe 30. The urine testing device 20 includes a collecting piece 21, and the collecting piece 21 can extend from the detection hole 12 and extend into the water seal groove 11 to collect urine.

[0037] The position of the detection hole 12 is higher than the position of the sewage outlet 13, and the driving device drives the sewage pipe 30 to move or switch the pipeline to change the height of the highest point of the water seal liquid level in the sewage pipe 30. In the normal water seal state, the highest point of the water seal liquid level in the sewage pipe 30 is higher than the detection hole 12; in the reduced water seal state, the highest point of the water seal liquid level in the sewage pipe 30 is lower than the detection hole 12. The state change of the sewage pipe 30 can be that the sewage pipe 30 itself changes its state through activities such as rotation, deformation, and expansion, or multiple pipelines or paths can be set on the sewage pipe 30, and the state change can be achieved by switching the pipelines.

[0038] See also Figures 1 to 4In some embodiments, in the normal water seal state, the highest point of the water seal liquid level in the sewage pipe 30 is located at the position of the outlet end 32. Therefore, to switch to the reduced water seal state, the sewage pipe can be driven by the driving device to move to change the position of the outlet end 32. In the normal water seal state, the position of the outlet end 32 is higher than the position of the detection hole 12; in the reduced water seal state, the outlet end 32 is adjusted downward, and the position of the outlet end 32 is lower than the position of the detection hole 12. After the outlet end 32 is adjusted downward, it must meet the position lower than the detection hole 12.

[0039] Preferably, the sewage pipe 30 includes an inlet section 301 and an outlet section 302, wherein the inlet section 301 is formed with an inlet end 31, and the outlet section 302 is formed with an outlet end 32, and the inlet section 301 is arranged along the central axis of the sewage outlet 13. The outlet end 32 can be rotated downward by 90° to 180°.

[0040] See also Figure 1 and Figure 2 In one embodiment, the sewage pipe 30 is a curved pipe, and the driving device drives the sewage pipe 30 to rotate around the central axis of the inlet end 31, thereby adjusting the position of the outlet end 32 of the sewage pipe 30. In the normal water seal state, the outlet end 32 faces upward, the outlet end 32 is higher than the detection hole 12, and the highest point of the water seal liquid level in the water seal groove 11 is higher than the detection hole 12; in the reduced water seal state, the outlet end 32 rotates downward, the outlet end 32 is lower than the detection hole 12, and the highest point of the water seal liquid level is lower than the detection hole 12.

[0041] The curved pipe structure of the sewage pipe 30 can be various, for example, the sewage pipe 30 can be a pipe made of hard material, the rib pipe can be a pipe bent at 90° or more than 90°, or an arc-shaped pipe. The outlet end 32 can be oriented differently from the inlet end 31, and the outlet end 32 and the inlet end 31 are not at the same height. When the water seal state is reduced, the downward rotation of the outlet end 32 means that the outlet end 32 is rotated downward relative to the position of the outlet end 32 in the normal water seal state, which can be rotated 90 degrees or more.

[0042] In one embodiment, see Figure 3 and Figure 4 The sewage pipe 30 includes an inlet section 301 and an outlet section 302, at least the outlet section 302 is deformable, the inlet section 301 is connected to the sewage outlet 13, and the outlet section 302 is connected to the discharge outlet, and the driving device can drive the outlet section 302 to swing up and down to change the position of the outlet end 32. In the normal water seal state, the outlet section 302 faces upward, so that the outlet end 32 is higher than the detection hole 12, and the water seal liquid level in the water seal groove 11 is higher than the detection hole 12; in the reduced water seal state, the outlet section 302 swings downward, so that the outlet end 32 is lower than the detection hole 12, and the water seal liquid level is lower than the detection hole 12.

[0043] The water inlet section 301 can be made of hard material or soft material, and the water outlet section 302 can be a hose. The water inlet section 301 can swing up and down together with the water outlet section 302, or the water inlet section 301 can remain in a fixed position. Preferably, the water inlet section 301 is fixed in position to ensure the stability of the matching relationship between the water inlet section 301 and the sewage outlet 13.

[0044] See also Figures 5 to 7 In some embodiments, the sewage pipe 30 is a curved pipe, and the middle part of the sewage pipe 30 has an arched portion 303. In the normal water seal state, the highest point of the water seal liquid level in the sewage pipe 30 is located at the arched portion 303. In the normal water seal state, the arched portion 303 is located above the sewage outlet 13, and the highest point of the bottom wall in the arched portion 303 is higher than the position of the detection hole 12; when the water seal state is reduced, the height of the arched portion 303 is lowered or the arched portion 303 is located below the sewage outlet 12, and the highest point of the bottom wall in the arched portion 303 is lower than the position of the detection hole 12.

[0045] In one embodiment, see Figure 5 , the sewage pipe 30 is a deformable curved pipe, and the driving device can drive the arched portion 303 of the sewage pipe 30 to deform upward or downward in the vertical direction to change the height of the arched portion 303. In the normal water seal state, the arched portion 303 of the sewage pipe 30 faces upward, and the highest point of the water seal liquid level is formed in the arched portion 303, and the position of the highest point of the water seal liquid level is higher than the detection hole 12, and the water seal liquid level formed in the water seal groove 11 is higher than the detection hole 12. When the water seal state is reduced, the arched portion 303 of the sewage pipe 30 deforms downward, and the arched portion 303 can be arched upward or concave downward, and the position of the highest point of the water seal liquid level in the arched portion 303 is lower than the detection hole 12, and the water seal liquid level formed in the water seal groove 11 is lower than the detection hole 12.

[0046] The structure of the sewage pipe 30 can be in various forms. In the normal water seal state, the positions of the inlet end 31 and the outlet end 32 of the sewage pipe 30 are lower than the position of the arched portion 303 in the middle, so that the water seal requirement of the sewage pipe 30 can be achieved. The sewage pipe 30 can be a hose, and the sewage pipe 30 can be deformed downward by pressing the driving device. The sewage pipe 30 can also be a retractable pipeline, and the sewage pipe 30 is shortened by the driving device, thereby driving the height of the arched portion 303 to decrease.

[0047] See also Figure 6 and Figure 7In one embodiment, the sewage pipe 30 is a curved pipe made of a hard material, and the driving device drives the sewage pipe 30 to rotate around the central axis of the inlet end 31 to change the direction of the arched portion 303 of the sewage pipe 30. In the normal water seal state, the arched portion 303 of the sewage pipe 30 bulges upward, the highest point of the water seal liquid level in the arched portion 303 is higher than the detection hole 12, and the water seal liquid level formed in the water seal groove 11 is higher than the detection hole 12; when the water seal state is reduced, the sewage pipe 30 is rotated to make the arched portion 303 move downward, the highest point of the water seal liquid level in the sewage pipe 30 is lower than the detection hole 12, and the water seal liquid level formed in the water seal groove 11 is lower than the detection hole 12.

[0048] The structure of the sewage pipe 30 can be an arc-shaped elbow or a V-shaped elbow. Preferably, the outlet end 32 and the inlet end 31 are on the same central axis. When the sewage pipe 30 rotates, the outlet end 32 can always rotate around the central axis of the inlet end 31, and the stability of the state switching of the sewage pipe 30 is good. When switching to the lowered water seal state, the sewage pipe 30 can be driven to rotate downward by 90° or more than 90°.

[0049] In one embodiment, see Figure 8 and Fig. 9 The sewage pipe 30 includes a main pipe 34 and a water seal pipe 33. A switching member 40 is provided in the sewage pipe 30. The driving device drives the switching member 40 to move to control the connection or disconnection of the main pipe 34. The highest point of the water seal liquid level of the water seal pipe 33 is higher than the detection hole 12, and the highest point of the water seal liquid level of the main pipe 34 is lower than the detection hole 12. In the normal water seal state, the main pipe 34 is disconnected, and the sewage flows to the sewage outlet after passing through the water seal pipe 33; when the water seal state is reduced, the main pipe 34 is connected, and the sewage flows directly to the sewage outlet through the main pipe 34.

[0050] In the embodiment, the main line 34 is in an inverted L-shape, the water seal line 33 is a U-shaped pipe, and the water seal line 33 is connected to the upstream and downstream of the main line 34 respectively. The switching member 40 is configured to be rotatable or translatable to switch between a first position and a second position. When the switching member 40 is in the first position, the main line 34 is disconnected, and the water seal line 33 can be water-sealed. Water exceeding the water seal liquid level can flow from the water seal line 33 to the downstream of the main line 34 and be discharged from the discharge port. When the switching member 40 is in the second position, the main line 34 is connected, and sewage can be discharged.

[0051] The sewage pipe 30 is provided with an installation cavity 35 for installing the switching member 40, and the switching member 40 includes a sealing piston that can reciprocate. The end of the sealing piston is configured to abut against the main line 34 to form a sealing fit to disconnect the main line 34, or to separate from the main line 34 to connect the main line 34.

[0052] See also Figures 1 to 9In some embodiments, an inflection point 14 is formed on the upper wall of the sewage outlet 13, and the inflection point 14 is lower than the detection hole 12. The water seal has a better deodorizing effect only when it is higher than the inflection point 14. The inflection point 14 is set below the detection hole 12, and the water seal liquid level can still be kept higher than the inflection point 14 during detection, which is conducive to maintaining a good deodorizing effect when the water seal state is reduced. Specifically, in the normal water seal state, the highest point of the water seal liquid level in the sewage pipe 30 is higher than the inflection point 14; in the reduced water seal state, the highest point of the water seal liquid level in the sewage pipe 30 is higher than the inflection point 14 and lower than the detection hole 12, and the water seal liquid level in the water seal groove 11 is higher than the inflection point 14 and lower than the detection hole 12.

[0053] The urine testing device 20 includes a urine testing preparation stage, a urine collecting stage, and a detection and analysis stage. The urine testing preparation stage is when the urine testing device 20 is in operation, the collecting member 21 is extended out of the detection hole 12 to prepare for urine collecting; the urine collecting stage is when the collecting member 21 is extended out of the detection hole 12 to collect the user's urine; the detection and analysis stage is when the collecting member 21 collects the user's urine and analyzes the user's urine.

[0054] The driving device starts the state switching operation according to the instruction of the urine test device 20. The driving device drives the sewage pipe 30 to switch to the reduced water seal state as needed during the urine test preparation stage, urine collection stage and detection and analysis stage. The urine test preparation stage, urine collection stage and detection and analysis stage do not need to always maintain the reduced water seal state, and during these stages, the state switching can be implemented once or multiple times.

[0055] Preferably, in the urine test preparation stage, the sewage pipe 30 is in a reduced water seal state; in the urine collection stage and the detection and analysis stage, the sewage pipe 30 always maintains the reduced water seal state. Alternatively, the sewage pipe 30 returns to the normal water seal state after the urine collection stage, and then in the detection and analysis stage, the driving device drives the sewage pipe 30 to switch to the reduced water seal state again; after the urine test is completed, the sewage pipe returns to the normal water seal state.

[0056] When the water seal is reduced, the sewage discharge capacity of the sewage pipe 30 is 0.1 to 300 L / min. In this state, when the inflow flow of the sewage pipe 30 is less than or equal to the sewage discharge capacity of the sewage pipe 30, the water seal liquid level in the water seal groove 11 is always lower than the detection port 12. Preferably, the central axis of the sewage outlet 13 is horizontal or nearly horizontal, and when the sewage pipe 30 is driven to move, such as rotating, rotating, etc., the eccentric rotation and rotation that causes the sewage pipe 30 to be out of engagement with the sewage outlet 13 are reduced.
