Description

Technical Field

[0001] The present invention relates to the technical field of intelligent toilets, and particularly relates to a wireless button remote control flushing device for an intelligent toilet and an implementation method thereof. Background Art

[0002] Chinese Patent CN211735636U discloses a wireless button remote control flushing device for a toilet, which includes a power adapter, a main body of the flushing device, and a wireless switch remote control. The main body of the flushing device includes a housing, a toilet flushing button, a wireless receiver, a telescopic electromagnet, and a telescopic pressure rod. The wireless receiver is located on one side outside the telescopic electromagnet, the telescopic pressure rod is located inside the telescopic electromagnet, the toilet flushing button is located above the telescopic pressure rod, a fuse is installed on one side of the inner wall of the telescopic electromagnet, and one end of the telescopic pressure rod penetrates through the telescopic electromagnet and extends to the lower part outside the telescopic electromagnet.

[0003] Although this application solves to a certain extent the technical problem in the background art that one needs to turn around and use a certain amount of force to press the flushing button to complete flushing after using the toilet, this application only solves the problem of pressing for flushing. When the toilet is in use, due to different sitting postures, after using the toilet, the position of dirt is not fixed. The existing toilet flushes water synchronously in a circle to wash the inner wall of the toilet, and cannot wash the concentrated dirt on the inner wall of the toilet specifically. Sometimes, secondary flushing is required, and even manual brushing is needed, which is inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide a wireless button remote control flushing device for an intelligent toilet and an implementation method thereof. An adjustable water outlet ring is arranged within a fixed frame. By changing the position of the water outlet ring, the water outlet position during toilet flushing is changed. In cooperation with the use of the lower support plate, when the position of the water outlet ring is changed, part of the water outlet is received, thereby realizing concentrated flushing, increasing the local water flushing volume, and improving the pertinence of flushing. When the water outlet ring is displaced, the lever principle is realized through a support rod, a balance rod, a support rod, and a push-pull rod. The water outlet ring drives the blocking block to move, that is, the leakage holes corresponding to the position of the water outlet ring with normal water outlet can also discharge water. A support spring is particularly arranged to connect the push-pull rod and the blocking block. In cooperation with the fact that the area of the inner wall of the blocking block is smaller than the area of the outer wall, the leakage holes corresponding to the water outlet ring that cannot discharge water normally do not discharge water either, which is convenient to control and easy to implement. A flushing button is arranged on the surface of the housing. There are five flushing buttons. Four flushing buttons roughly divide the inner wall of the toilet seat into four areas. Different waterproof motors correspond to different areas. The user can select the corresponding flushing button for flushing according to the specific position of the dirt, which is easy to judge and convenient to use, so as to solve the problems raised in the above background art.

[0014] A plurality of rollers are arranged on the edge of each lifting cam. The diameter of the rollers is parallel to the axial direction of the output shaft of the waterproof motor, and the rollers are in rolling contact with the water outlet ring.

[0015] Another technical problem to be solved by the present invention is to provide an implementation method of a wireless button remote control flushing device for a smart toilet, including the following steps:

[0016] S1: The user selects the corresponding flushing button according to the specific position of the dirt for flushing. After the processor receives the flushing requirement, it determines the area position that needs to be focused on flushing and the corresponding waterproof motor, and at the same time takes corresponding measures for the areas that do not need to be focused on flushing, and issues a flushing instruction to the waterproof motors in the whole area;

[0017] S2: The communication module receives the instruction. According to the instruction indication, the driving module in the area that needs to be focused on flushing controls the waterproof motor to rotate the lifting cam to eject the water outlet ring, and the driving module in the area that does not need to be focused on flushing controls the waterproof motor to rotate the lifting cam to a position adapted to the water outlet ring;

[0018] S3: The position of the water outlet ring is shifted. One side of the water outlet ring in the area that needs to be focused on flushing moves outside the lower support plate, and the corresponding water leakage hole of the water outlet ring is opened. One side of the water outlet ring in the area that does not need to be focused on flushing moves above the lower support plate, and the corresponding water leakage hole of the water outlet ring is blocked;

[0019] S4: The water outlet ring intakes water through the water inlet hose. The water outlet ring in the area that needs to be focused on flushing sprays water obliquely onto the inner wall of the toilet seat. At the same time, the water sprayed by the water outlet ring in the area that does not need to be focused on flushing is received by the lower support plate, collected by the water through-flow groove, and discharged into the toilet seat through the water leakage hole in the area that needs to be focused on flushing;

[0020] S5: After flushing is completed, the waterproof motor drives the lifting cam to reset, and the water outlet ring returns to the initial position.

[0021] Preferably, when flushing for the first time, the initial velocity of the water sprayed by the water outlet rings in each flushing area is detected, including the key initial velocity and the ordinary initial velocity, and the average value of the key initial velocity and the average value of the ordinary initial velocity are respectively calculated and saved;

[0022] Every time flushing is performed later, the water flow velocity of the water sprayed by the water outlet rings in each flushing area is detected, including the key water flow velocity and the ordinary water flow velocity, and the attenuation index of the flushing velocity is calculated using the following formula:

[0023]

[0024] In the above formula, τ represents the decay exponent of the flushing speed; n represents the number of water outlet rings in the key flushing area of this flushing; V i represents the key water flow speed of the water outlet ring in the i-th key flushing area of this flushing; represents the average value of the key initial speed of the water outlet ring in the key flushing area during the first flushing saved; m represents the number of water outlet rings in the flushing area that does not require key flushing this time; V j represents the normal water flow speed of the water outlet ring in the j-th flushing area that does not require key flushing this time; represents the average value of the normal initial speed of the water outlet ring in the flushing area that does not require key flushing during the first flushing saved;

[0025] If the calculated decay exponent of the flushing speed exceeds the preset decay threshold, a prompt message for cleaning the water outlet ring is sent.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In the prior art, a water outlet device is directly provided at the upper end of the toilet seat, and the position of the water outlet device is fixed, and the position of the water outlet hole cannot be adjusted. In the present invention, a movable water outlet ring is provided in the fixed frame. By changing the position of the water outlet ring, the water outlet position during toilet flushing is changed. With the use of the lower support plate, after the position of the water outlet ring is changed, part of the water outlet is received, so as to realize concentrated flushing, increase the local flushing amount, improve the pertinence of flushing, focus on flushing the dirt position on the inner wall of the toilet seat, improve the flushing cleanliness, save water resources, and avoid repeated flushing;

[0028] 2. When the water outlet ring is displaced, the lever principle is realized through the support rod, balance rod, support rod and push-pull rod. The water outlet ring drives the plugging block to move, that is, the water leakage hole corresponding to the position of the normally water outlet water outlet ring can also discharge water. A support spring is specially provided to connect the push-pull rod and the plugging block. With the area of the inner wall of the plugging block being smaller than the outer wall area, the water leakage hole corresponding to the water outlet ring that cannot normally discharge water does not discharge water either. The water outlet ring and the plugging block are interlocked, and the automatic adjustment of the plugging block can be realized by adjusting the position of the water outlet ring, without providing a driving force for the plugging block, which is convenient to control and easy to realize;

[0029] 3. A flushing button is provided on the surface of the shell. There are five flushing buttons. Four flushing buttons roughly divide the inner wall of the toilet seat into four areas. Different areas correspond to different waterproof motors. The user selects the corresponding flushing button to flush according to the specific position of the dirt. Through the judgment of the user, targeted toilet flushing after using the toilet is realized. The shape of the flushing button is set to be corresponding to the shape of the toilet seat, which is convenient for the user to use, easy to judge, and convenient and simple.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1-8, An intelligent toilet wireless button remote control flushing device, including a water outlet ring 1 arranged at the upper end of the toilet seat and a wireless remote control 5. A fixed frame 2 is sleeved outside the water outlet ring 1, and the fixed frame 2 is fixedly connected to the upper end of the toilet seat. The fixed frame 2 includes an upper cover plate 21, a lower support plate 22 and a side plate 23. The upper and lower ends of the side plate 23 are respectively connected to the upper cover plate 21 and the lower support plate 22. The water outlet ring 1 is arranged in the space surrounded by the upper cover plate 21, the lower support plate 22 and the side plate 23. A waterproof motor 3 is embedded in the side wall of the side plate 23, and the waterproof motor 3 is wirelessly connected to the wireless remote control 5. A water blocking ring 4 is arranged on the lower surface of the lower support plate 22, and the water blocking ring 4 is movably connected to the water outlet ring 1.

[0042] A water through groove 221 matching the size of the water outlet ring 1 is opened on the upper surface of the lower support plate 22, and a water leakage hole 222 penetrating the lower support plate 22 is opened in the water through groove 221.

[0043] Specifically, the water outlet ring 1 is arranged above the water through groove 221. The water of the water outlet ring 1 crosses the lower support plate 22 and sprays obliquely onto the inner wall of the toilet seat. When the position of the water outlet ring 1 is offset, the water spraying direction remains unchanged when the water outlet ring 1 is placed outside the lower support plate 22. When the water outlet ring 1 is placed above the lower support plate 22, the sprayed water is received by the lower support plate 22, collected by the water through groove 221, and discharged into the toilet seat through the water leakage hole 222.

[0044] One end of the water outlet ring 1 is provided with a water inlet hose 11. One end of the water inlet hose 11 is connected to the toilet water tank. Water outlet holes 12 inclined downward are opened on the inner wall of the water outlet ring 1. A support rod 13 is arranged on the outer wall of the water outlet ring 1. The support rod 13 penetrates the side plate 23, and one end of the support rod 13 outside the side plate 23 is hinged with a balance rod 14.

[0045] Specifically, the water outlet ring 1 is filled with water through the water inlet hose 11, and the water entering the water outlet ring 1 is discharged through the water outlet holes 12. The support rod 13 fixes the circumference of the water outlet ring 1, so that the water outlet ring 1 is suspended. When the water outlet ring 1 is pushed, the support rod 13 will stretch on the side plate 23, driving the balance rod 14 to tilt. The balance rod 14 is used to fix the position of the support rod 13 and drive the water blocking ring 4 to move at the same time.

[0046] An activity hole 231 matching the support rod 13 is opened on the side plate 23. A support rod 232 is arranged on the outer wall of the side plate 23. One end of the support rod 232 is hinged with the balance rod 14. A cam groove 233 is opened on the outer wall of the side plate 23 close to the waterproof motor 3.

[0047] Specifically, the balance rod 14 can rotate around the support rod 232. When the upper end of the balance rod 14 inclines towards the inner circle of the water outlet ring 1, the lower end of the balance rod 14 drives the connected water blocking ring 4 to move outwards from the outer circle of the lower support plate 22, and the water leakage hole 222 is exposed.

[0048] See also Figures 3-9 A lifting cam 31 is provided at the output end of the waterproof motor 3. The lifting cam 31 passes through the cam groove 233, and one side of the lifting cam 31 contacts the outer wall of the water outlet circle 1. A driving module 32 and a communication module 33 are provided in the waterproof motor 3. The driving module 32 is used to control the start and stop of the waterproof motor 3. The communication module 33 is wirelessly connected to the wireless remote control 5, and the communication module 33 receives the flushing instruction of the wireless remote control 5.

[0049] Specifically, the communication module 33 receives the flushing instruction and controls the driving module 32 to work. The driving module 32 controls the start and stop of the waterproof motor 3. The waterproof motor 3 rotates, driving the lifting cam 31 to rotate. The lifting cam 31 pushes the water outlet ring 1 to move horizontally, changing the relative position of the water outlet ring 1 and the lower support plate 22. When the lifting cam 31 pushes out one side of the water outlet ring 1, the other side of the water outlet ring 1 is correspondingly retracted, and the lifting cam 31 corresponding to the retracted side of the water outlet ring 1 rotates accordingly to a position adapted to the position of the water outlet ring 1.

[0050] The water blocking ring 4 includes a blocking block 41 that can be spliced into a size equal to the lower support plate 22. The blocking block 41 is movably connected to the lower surface of the lower support plate 22 through a slider. The blocking block 41 cannot be separated from the lower support plate 22, and the blocking block 41 moves along the surface of the lower support plate 22. A support spring 42 is provided on the outer wall of the blocking block 41. A push-pull rod 43 is sleeved on one end of the support spring 42. The end of the push-pull rod 43 away from the support spring 42 is hinged to the balance rod 14.

[0051] Specifically, the position of the water outlet ring 1 is offset, and one side of the water outlet ring 1 moves to above the lower support plate 22, then the upper end of the balance rod 14 is pushed to move away from the side plate 23, and the lower end of the balance rod 14 moves toward the side plate 23. At this time, the push-pull rod 43 squeezes the support spring 42, and the support spring 42 reacts to the blocking block 41, but the blocking block 41 is annular in structure as a whole, and the area of the inner wall of the blocking block 41 is smaller than the area of the outer wall, so that the blocking block 41 cannot move toward the center. The support spring 42 shrinks, and the blocking block 41 still blocks the water leakage hole 222 at the corresponding position. The water outlet ring 1 moves to the position above the lower support plate 22 without draining water or a small amount of water overflows from the water trough 221 to the inner wall of the toilet.

[0052] On the contrary, the lower end of the balance rod 14 at the symmetrical position of the water outlet ring 1 drives the push-pull rod 43 connected thereto to move downward along the outer ring of the lower support plate 22. The push-pull rod 43 pulls the plugging block 41 to move downward along the outer ring of the lower support plate 22 through the support spring 42. The water leakage holes 222 blocked by the plugging block 41 are opened, and the water entering the water trough 221 can be discharged through the water leakage holes 222 here. At the same time, the water outlet ring 1 at the position corresponding to the opened water leakage holes 222 also moves out of the lower support plate 22, and the water outlet ring 1 discharges water normally. At the same time, the water leakage holes 222 collect and discharge the water from other places, increasing the water output at this place.

[0053] The wireless remote control 5 includes a housing 51, a flushing button 52 and a processor 53. The processor 53 is installed in the housing 51. The flushing button 52 is arranged on the surface of the housing 51. There are five flushing buttons 52. The flushing button 52 is communicatively connected to the processor 53. The processor 53 is wirelessly connected to the communication module 33. The processor 53 receives the flushing requirement through the flushing button 52, and after processing, sends the flushing instruction to the communication module 33.

[0054] Specifically, four flushing buttons 52 are area flushing keys. The four flushing buttons 52 are spliced into the top view contour shape of the toilet seat. A normal flushing button is arranged at the center of the four flushing buttons 52. The four flushing buttons 52 roughly divide the inner wall of the toilet seat into four areas. Different areas correspond to different waterproof motors 3. The user selects the corresponding flushing button 52 for flushing according to the specific position of the dirt. The normal flushing button does not change the flushing position. After the processor 53 receives the flushing requirement, it issues a working instruction to the waterproof motors 3 in the whole area and turns on the flushing button at the same time. The communication module 33 receives the instruction and controls the waterproof motors 3 to work through the driving module 32.

[0055] In some embodiments, each plugging block 41 corresponds to at least two water leakage holes 222, so that each plugging block 41 can block at least two water leakage holes 222. At least the surface area of the plugging block 41 can be made of rubber material, and the rubber material can play a good sealing role to ensure that the water leakage holes 222 do not leak under the action of the plugging block 41.

[0056] Among them, the plugging block 41 is in an arc shape or a fan shape; the shape jointly surrounded by all the plugging blocks 41 is similar to or the same as the shape of the fixed frame 2.

[0057] The lower support plate 22 and the side plate 23 are integrally formed and made of the same material, which can ensure good structural strength and product consistency. The lower support plate 22 is perpendicular to the side plate 23, and the upper cover plate 21 is detachably connected to the side plate 23; when installing the water outlet ring 1, first open the upper cover plate 21, embed the water outlet ring 1 at the corner between the lower support plate 22 and the side plate 23, then cover the upper cover plate 21 on the water outlet ring 1, and fix the upper cover plate 21 to the side plate 23.

[0058] A plurality of rollers are arranged on the edge of each lifting cam 31, and the diameter of the rollers is parallel to the axial direction of the output shaft of the waterproof motor 3. The rollers are in rolling contact with the water outlet ring 1, so that when the lifting cam 31 rotates, the rollers can roll and rub against the water outlet ring 1, thereby reducing the wear on the water outlet ring 1 and reducing the output power of the waterproof motor 3.

[0059] In order to better demonstrate the implementation process of the wireless button remote control flushing device for a smart toilet, this embodiment now proposes an implementation method of the wireless button remote control flushing device for a smart toilet, including the following steps:

[0060] Step 1: The user selects the corresponding flush button 52 to flush according to the specific location of the dirt. After receiving the flushing request, the processor 53 determines the location of the area that needs to be flushed and the corresponding waterproof motor 3. At the same time, the corresponding area that does not need to be flushed is prepared with corresponding measures, and a flushing instruction is issued to the waterproof motors 3 in the entire area;

[0061] Step 2: The communication module 33 receives the instruction. According to the instruction, the driving module 32 of the key flushing area controls the waterproof motor 3 to rotate the lifting cam 31 to push out the water outlet circle 1. The driving module 32 of the non-key flushing area controls the waterproof motor 3 to rotate the lifting cam 31 to a position suitable for the water outlet circle 1.

[0062] Step 3: The position of the water outlet ring 1 is offset, and one side of the water outlet ring 1 in the area where flushing is required is moved to the outside of the lower support plate 22, where the corresponding leakage hole 222 of the water outlet ring 1 is opened, and the lower end of the balance rod 14 at the symmetrical position of the water outlet ring 1 drives the push-pull rod 43 connected thereto to move toward the outer ring of the lower support plate 22, and the push-pull rod 43 pulls the blocking block 41 to move toward the outer ring of the lower support plate 22 through the support spring 42, and the leakage hole 222 blocked by the blocking block 41 is opened, and the water entering the water channel 221 can be discharged through the leakage hole 222 here;

[0063] One side of the water outlet ring 1 in the area that does not need to be flushed is moved to the top of the lower support plate 22, and the corresponding water leakage hole 222 of the water outlet ring 1 is blocked. When one side of the water outlet ring 1 is moved to the top of the lower support plate 22, the upper end of the balance rod 14 is pushed to move away from the side plate 23, and the lower end of the balance rod 14 moves toward the side plate 23. The area of the inner wall of the blocking block 41 is smaller than the area of the outer wall, so that the blocking block 41 cannot move toward the center. The support spring 42 contracts, and the blocking block 41 still blocks the water leakage hole 222 at the corresponding position. The water outlet ring 1 moves to the position above the lower support plate 22, and no water is discharged or a small amount of water overflows from the water channel 221 to the inner wall of the toilet.

[0064] Step 4: The water outlet ring 1 is filled with water through the water inlet hose 11. The water outlet ring 1 in the area that needs to be flushed intensively sprays water obliquely onto the inner wall of the toilet seat. At the same time, the water sprayed by the water outlet ring 1 in the area that does not need to be flushed intensively is received by the lower support plate 22, collected by the water through-flow groove 221, and discharged into the toilet seat through the water leakage holes 222 in the area that needs to be flushed intensively;

[0065] Step 5: After flushing is completed, the waterproof motor 3 drives the lifting cam 31 to reset, and the water outlet ring 1 returns to its initial position.

[0066] In summary: An intelligent toilet wireless button remote control flushing device and its implementation method proposed by the present invention are provided with a movable water outlet ring 1 in the fixed frame 2. By changing the position of the water outlet ring 1, the water outlet position during toilet flushing is changed. In cooperation with the use of the lower support plate 22, after the position of the water outlet ring 1 is changed, part of the water outlet is received, so as to achieve concentrated flushing, increase the local water flushing volume, and improve the pertinence of flushing; when the water outlet ring 1 is displaced, the lever principle is realized through the support rod 13, the balance rod 14, the support rod 232 and the push-pull rod 43. The water outlet ring 1 drives the blocking block 41 to move, that is, the water leakage holes 222 corresponding to the position of the normally discharging water outlet ring 1 can also discharge water. A support spring 42 is specially provided to connect the push-pull rod 43 and the blocking block 41. In cooperation with the fact that the area of the inner wall of the blocking block 41 is smaller than the area of the outer wall, the water leakage holes 222 corresponding to the water outlet ring 1 that cannot discharge water normally do not discharge water either, which is convenient to control and easy to implement; a flushing button 52 is provided on the surface of the housing 51. There are five flushing buttons 52. Four flushing buttons 52 roughly divide the inner wall of the toilet seat into four areas. Different areas correspond to different waterproof motors 3. The user selects the corresponding flushing button 52 for flushing according to the specific position of the dirt, which is easy to judge and convenient to use.

[0067] An intelligent controller is set on the intelligent toilet. The wireless remote control 5 is connected to the intelligent controller wirelessly. The intelligent controller is electrically connected to the waterproof motor 3. The intelligent controller is connected with a plurality of flushing speed sensors, and the flushing speed sensors are used to detect the jet water flow speed of the water outlet rings in each flushing area;

[0068] When flushing for the first time, the flushing speed sensors detect the initial speeds of the jet water of the water outlet rings in each flushing area, including the key initial speed and the normal initial speed, and calculate the average value of the key initial speed and the average value of the normal initial speed respectively, which are saved by the intelligent controller;

[0069] Every time flushing is carried out later, the flushing speed sensors detect the water flow speeds of the jet water of the water outlet rings in each flushing area, including the key water flow speed and the normal water flow speed. The intelligent controller uses the following formula to calculate the attenuation index of the flushing speed:

[0070]

[0071] In the above formula, τ represents the attenuation index of flushing speed; n represents the number of water outlet circles in the key flushing area of this flushing; V i Indicates the key water flow velocity of the water outlet circle of the i-th key flushing area of this flushing; represents the average initial velocity of the water outlet circle of the key flushing area during the first flushing; m represents the number of water outlet circles in the flushing area that does not need key flushing this time; V j It represents the normal water flow velocity of the water outlet circle of the j-th flushing area that does not need to be flushed; It indicates the average value of the common initial velocity of the water outlet circle of the flushing area which does not need to be flushed during the first flushing;

[0072] If the calculated attenuation index of the flushing speed exceeds the attenuation threshold preset in the intelligent controller, the intelligent controller will issue a prompt message that the water outlet circle needs to be cleaned.

[0073] During the first flush, the flush speed sensor detects the initial speed of the jet water of the water outlet circle of each flushing area, and the calculated average value of the key initial speed and the average value of the common initial speed are used as reference data, instead of directly using the set fixed design data as a reference. This can avoid false alarms caused by large deviations in the calculation results due to toilet installation in the project (such as local altitude, project water supply pressure, etc.) and debugging differences (such as water level debugging of the water tank, etc.); by calculating the attenuation index of the toilet flush speed and comparing it with the preset attenuation threshold, the attenuation effect of the accumulation of scale and the like in the water outlet during use can be effectively evaluated, and a prompt can be given to clean it in time, thereby ensuring the flushing speed and flushing effect of the toilet, and avoiding unclean flushing of the toilet due to excessive attenuation of the flush speed and failure to clean it in time, or requiring multiple flushings to waste water resources.

[0074] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
