Description

Technical Field

[0001] This application relates to the field of sanitary ware technology, and in particular to a positioning device and a toilet. Background Technology

[0002] In the production process of smart toilets, sensors need to be attached to fixed positions on the S-bend to detect siphon signals within the S-bend. When a siphon signal is detected, the flushing system can automatically adjust the flush volume to avoid over-flushing and thus save water. In related technologies, when attaching sensors, it is usually done manually by visually inspecting the sensor positions on the sample before attaching the sensors to the new product.

[0003] The inventors of this application have discovered that manual visual inspection has low accuracy and makes it difficult to ensure the consistency of sensor mounting positions, which can easily lead to large differences in sensor detection signals and cause inconvenience.

[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] It should be noted that this application uses the application of the positioning device to a toilet as an example for illustration. The positioning device can also be applied to other products or equipment that require positioning, such as automobiles, ships, drones, etc.

[0022] Please see Figure 1 The toilet 1000 includes a toilet body 10, a sensor 20, and a positioning device 30. The positioning device 30 is mounted on the toilet body 10 and is used to form a positioning area on the S-bend of the toilet body 10. The sensor 20 is disposed in the positioning area. In some embodiments, a laser 34 on the positioning device 30 emits a positioning laser towards the S-bend, forming a positioning area on the S-bend, and the sensor 20 is disposed in the positioning area. The toilet body 10, sensor 20, and positioning device 30 are described in detail below.

[0023] Regarding the toilet body 10 mentioned above, such as Figure 1 and Figure 2 As shown, the toilet body 10 is provided with a receiving cavity 10a and an opening 10b communicating with the receiving cavity 10a. The S-bend of the toilet body 10 is located inside the receiving cavity 10a, and the positioning device 30 is placed at the opening 10b of the receiving cavity 10a.

[0024] To better explain the structure of the positioning device 30, it will be described in conjunction with the first direction X, the second direction Y, and the vertical direction Z, wherein the first direction X is perpendicular to the second direction Y and the vertical direction Z.

[0025] Regarding the aforementioned sensor 20 and positioning device 30, such as Figure 1 and Figure 2As shown, the positioning device 30 includes a base 31, a connecting plate 32, a moving component 33, and a laser 34. The base 31 has a first surface 31a and a second surface 31b arranged opposite each other in the vertical Z direction. A positioning groove 31c is also provided on the base 31, extending from the first surface 31a to the second surface 31b. The base 31 can be installed on the toilet body 10, and the positioning groove 31c is opposite to the S-bend on the toilet body 10. The connecting plate 32 is disposed on the first surface 31a and connected to the base 31. The connecting plate 32 is located at the edge of the positioning groove 31c, and the connecting plate 32 can be positioned relative to the... The base 31 moves, and the moving component 33 is set on the connecting plate 32. The moving component 33 includes a first moving plate 331, which can move relative to the connecting plate 32 in the vertical direction Z. The laser 34 is connected to the first moving plate 331 and can move with the first moving plate 331. The laser 34 can emit a positioning laser towards the S-bend on the toilet body 10. The positioning laser forms a positioning area on the S-bend. The sensor 20 is set in the positioning area and can be used to detect the siphon signal in the S-bend.

[0026] It should be noted that during the use of the positioning device 30, the user can first place the positioning device 30 on the sample, and adjust the position of the connecting plate 32 and the first moving plate 331 according to the position of the sensor 20 on the sample, so that the positioning laser emitted by the laser 34 on the positioning device 30 corresponds to the position of the sensor 20 on the sample. Then, the positioning device 30 with the laser 34 adjusted is placed on the new product, and the laser 34 emits a positioning laser towards the new product. The user then attaches the sensor 20 to the positioning laser position on the new product, thereby achieving precise attachment of the sensor 20 to the new product, ensuring the consistency of the attachment position of the sensor 20 on multiple new products, and thus reducing the difference between the detection signals of the sensor 20.

[0027] In some embodiments, please refer to the following: Figure 3The base 31 has a first connecting hole 311 at one end along the first direction X. The connecting plate 32 is located at one end of the base 31 along the first direction X. The connecting plate 32 has a first moving groove 321 that extends along the second direction Y. The first moving groove 321 is opposite to the first connecting hole 311. The connecting plate 32 also has a first connecting screw 322 that passes through the first moving groove 321 and connects to the first connecting hole 311. When the first connecting screw 322 is in the locked state, the connecting plate 32 is relatively fixed to the base 31. When the first connecting screw 322 is in the loosened state, the connecting plate 32 can move relative to the base 31 along the second direction Y, thereby enabling the laser 34 to move along the second direction Y, that is, to adjust the position of the laser 34 along the second direction Y. It is understandable that, in order to enable the connecting plate 32 to move relative to the base 31 along the second direction Y, the connection method between the connecting plate 32 and the base 31 is not limited to the above, and can also be other structures, such as the connection method of the connecting plate 32 and the base 31 using a slide rail, a slider, etc.

[0028] In some embodiments, such as Figure 3 As shown, the movable component 33 includes a fixed sleeve 332 and a locking member 333. The fixed sleeve 332 is fixed to the connecting plate 32 and extends vertically in the Z direction. The fixed sleeve 332 is provided with an installation space 332a and a locking hole 332b communicating with the installation space 332a. The locking hole 332b is located on the outer wall of the fixed sleeve 332. One end of the first movable plate 331 is inserted into the installation space 332a, and the other end of the first movable plate 331 is connected to the laser 34. The first movable plate 331 can move relative to the fixed sleeve 332 along... The laser 34 moves vertically upwards (Z-direction), emitting a positioning laser beam towards the S-bend. The locking member 333 is inserted into the locking hole 332b. When the locking member 333 abuts against the first moving plate 331, the first moving plate 331 is relatively fixed to the fixing sleeve 332. When the locking member 333 is not abutting against the first moving plate 331, the first moving plate 331 can move vertically upwards (Z-direction) within the installation space 332a, thereby enabling the laser 34 to move vertically upwards (Z-direction), i.e., adjusting the position of the laser 34 vertically upwards (Z-direction). It is understood that to enable the first moving plate 331 to move vertically upwards (Z-direction), the structure is not limited to the above; other structures can also be used, such as a connection between a cylinder and a telescopic rod, etc.

[0029] In some embodiments, the first movable plate 331 is provided with a second connecting hole 331a at one end away from the base 31. The movable assembly 33 also includes a second movable plate 334. The second movable plate 334 is provided with a second movable through groove 3341 and a second connecting screw 3342. The second movable through groove 3341 extends upward along the first direction X and is disposed opposite to the second connecting hole 331a. The second connecting screw 3342 passes through the second movable through groove 3341 and connects to the second connecting hole 331a. The laser 34 is disposed at one end of the second movable plate 334 away from the first movable plate 331. When the second connecting screw 3342 is in the locked state, the second movable plate 334 is relatively fixed to the first movable plate 331. When the second connecting screw 3342 is in the loosened state, the second movable plate 334 can move relative to the first movable plate 331 upward along the first direction X, thereby driving the laser 34 to move upward along the first direction X, thereby adjusting the position of the laser 34 upward along the first direction X.

[0030] It is understandable that, in order to enable the first moving plate 331 in the moving component 33 to move relative to the base 31 in the vertical direction Z, the structure of the moving component 33 may be other than the one described above, as will be explained in detail below.

[0031] In some embodiments, such as Figure 4 and Figure 5 As shown, the moving component 33 includes a fixed plate 335 and a third moving plate 336. The fixed plate 335 is disposed on the connecting plate 32. The end of the fixed plate 335 facing away from the connecting plate 32 is connected to the third moving plate 336. The third moving plate 336 can move relative to the fixed plate 335 along the first direction X. The end of the third moving plate 336 facing away from the fixed plate 335 is connected to the first moving plate 331. The laser 34 is disposed on the first moving plate 331. The laser 34 emits a positioning laser 34a along the vertical direction Z towards the S-bend direction. When the third moving plate 336 moves relative to the fixed plate 335 along the first direction X, it can drive the laser 34 to move along the first direction X, thereby adjusting the position of the laser 34 in the first direction X.

[0032] In some embodiments, the fixed plate 335 has a third connecting hole 3351 at one end away from the connecting plate 32, and the third moving plate 336 has a third moving groove 3361 and a third connecting screw 3362. The third moving groove 3361 extends upward along the first direction X and is disposed opposite to the third connecting hole 3351. The third connecting screw 3362 passes through the third moving groove 3361 and connects to the third connecting hole 3351. When the third connecting screw 3362 is in the locked state, the third moving plate 336 is relatively fixed to the fixed plate 335. When the third connecting screw 3362 is in the loosened state, the third moving plate 336 can move relative to the fixed plate 335 along the first direction X, thereby enabling the third moving plate 336 to move relative to the fixed plate 335 along the first direction X, and thus the third moving plate 336 can drive the laser 34 to move along the first direction X.

[0033] In some embodiments, the third movable plate 336 has a fourth connecting hole 3363 at one end opposite to the fixed plate 335. The first movable plate 331 has a fourth movable through groove 3311 and a fourth connecting screw 3312. The fourth movable through groove 3311 extends vertically in the Z direction and is opposite to the fourth connecting hole 3363. The fourth connecting screw 3312 passes through the fourth movable through groove 3311 and connects to the fourth connecting hole 3363. When the fourth connecting screw 3312 is in the locked state, the first movable plate 331 is relatively fixed to the third movable plate 336. When the fourth connecting screw 3312 is in the loosened state, the first movable plate 331 can move vertically in the Z direction relative to the third movable plate 336, thereby enabling the first movable plate 331 to move vertically in the Z direction relative to the base 31, thereby driving the laser 34 to adjust its position in the vertical Z direction.

[0034] It is understandable that, in addition to being located on one side of the base 31 along the first direction X, the connecting plate 32 can also be located at one end of the base 31 along the second direction Y. In this case, the laser 34 can emit a positioning laser towards the S-bend along the second direction Y.

[0035] In some embodiments, such as Figure 6 and Figure 7As shown, the connecting plate 32 is disposed at one end of the base 31 along the second direction Y. The connecting plate 32 is provided with a fifth connecting hole 323 on the side near the positioning groove 31c. The first moving plate 331 is provided with a fifth moving through groove 3313 and a fifth connecting screw 3314. The fifth moving through groove 3313 extends along the vertical direction Z and is disposed opposite to the fifth connecting hole 323. The fifth connecting screw 3314 passes through the fifth moving through groove 3313 and connects to the fifth connecting hole 323. The laser 34 is disposed on the first moving plate 331 and emits a positioning laser along the second direction Y toward the direction of the tube to be bent. When the fifth connecting screw 3314 is in the locked state, the first moving plate 331 is relatively fixed to the connecting plate 32. When the fifth connecting screw 3314 is in the loosened state, the first moving plate 331 can move relative to the connecting plate 32 along the vertical direction Z, thereby driving the laser 34 to move along the vertical direction Z.

[0036] In some embodiments, please refer to the following: Figure 8 The positioning device 30 also includes a first limiting block 35 and a second limiting block 36. Both the first limiting block 35 and the second limiting block 36 are disposed on the second surface 31b. The first limiting block 35 is detachably connected to one end of the base 31 along the second direction Y, and the second limiting block 36 is detachably connected to the other end of the base 31 along the second direction Y. The first limiting block 35 and the second limiting block 36 can move closer to each other or away from each other along the second direction Y, thereby adjusting the distance between the first limiting block 35 and the second limiting block 36 along the second direction Y. As a result, the first limiting block 35 and the second limiting block 36 can be installed on toilet bodies 10 of different sizes, so that the positioning device 30 is more stably installed on the toilet body 10 along the second direction Y. It is understandable that the first limiting block 35 and the second limiting block 36 can move closer to each other or further apart along the second direction Y. That is, the first limiting block 35 can move relative to the base 31 along the second direction Y, and the second limiting block 36 can move relative to the base 31 along the second direction Y. The specific principle can be referred to the connection method between the third moving plate 336 and the first moving plate 331 mentioned above, which will not be repeated here.

[0037] In some embodiments, the positioning device 30 further includes a fixing block 37 and a third limiting block 38. Both the fixing block 37 and the third limiting block 38 are disposed on the second surface 31b. Both the fixing block 37 and the third limiting block 38 are detachably connected to one end of the base 31 along the first direction X. The fixing block 37 and the third limiting block 38 are positioned opposite each other and spaced apart along the first direction X. The third limiting block 38 can move along the first direction X towards or away from the fixing block 37, thereby adjusting the distance between the third limiting block 38 and the fixing block 37 along the first direction X. This allows the third limiting block 38 and the fixing block 37 to be engaged with toilet bodies 10 of different thicknesses, making the positioning device 30 more stably installed on the toilet body 10 along the first direction X. It is understood that the third limiting block 38 can move relative to the base 31 along the first direction X. The specific principle can be referred to the connection method between the third moving plate 336 and the first moving plate 331 described above, and will not be repeated here.

[0038] In some embodiments, the base 31, connecting plate 32, first moving plate 331, second moving plate 334, third moving plate 336 and fixed plate 335 are all provided with scales, so that when adjusting the position of the laser 34 in the corresponding directions X, Y and Z, the position of the laser 34 can be recorded by the scales.

[0039] In this embodiment, a base 31, a connecting plate 32, a moving component 33, and a laser 34 are provided. The base 31 has a first surface 31a and a second surface 31b arranged opposite each other in the vertical direction Z. A positioning groove 31c is also provided on the base 31, extending from the first surface 31a to the second surface 31b. The base 31 can be installed on a product to be positioned, and the positioning groove 31c is partially opposite to the product to be positioned. The connecting plate 32 is disposed on the first surface 31a and connected to the base 31. The connecting plate 32 is located at the edge of the positioning groove 31c and can move relative to the base 31. The moving component 33 is disposed on the connecting plate 32 and includes a first moving plate 331, which can move relative to the connecting plate 32 in the vertical direction Z. The laser 34 is connected to the first moving plate 331 and can move with the first moving plate 331. The laser 34 can emit a positioning laser towards the product to be positioned. Compared with the manual visual positioning method in related technologies, in this embodiment, the user can first place the positioning device 30 on the sample and adjust the position of the connecting plate 32 and the first moving plate 331 according to the position of the sensor 20 on the sample, so that the positioning laser emitted by the laser 34 on the positioning device 30 corresponds to the position of the sensor 20 on the sample. Then, the positioning device 30 with the laser 34 adjusted is placed on the new product, and the laser 34 emits a positioning laser towards the new product. The user then attaches the sensor 20 to the positioning laser position on the new product, thereby achieving precise attachment of the sensor 20 to the new product, ensuring the consistency of the attachment position of the sensor 20 on multiple new products, and reducing the difference between the detection signals of the sensor 20.
