The controller is electrically connected to the motor 6. The infrared sensor 5 is electrically connected with the controller. The infrared sensor 5 in this embodiment includes a distance measurement module and a ray module.
The working principle of the intelligent toilet lid in this embodiment will be explained in detail.
When a user approaches and reaches the trigger distance set by the distance measuring module of the infrared sensor 5, the infrared sensor 5 transmits a trigger signal to the controller, the controller sends a rotation signal to the motor 6 according to the received trigger signal, and the motor 6 drives the driving wheel to rotate according to the received rotation signal. At this time, the first stopper 409 of the first wheel 406 pushes the second protrusion 414 at the fixed end of the transmission shaft of the toilet upper cover to rotate, and the transmission shaft of the toilet upper cover rotates therewith, and simultaneously the first protrusion 413 of the first shifting tooth 412 rotates from the long axis position to the short axis position in the elliptical hole of the first elliptical member 403. The first protrusion 413 gradually shrinks when rotating from the long axis position to the short axis position, and when the short axis position is completely shrunk to the inside of the fixed end of the transmission shaft of the upper cover of the toilet, the second protrusion 414 shrinks along with the first protrusion 413, and when the transmission shaft of the upper cover of the toilet rotates 90 degrees, the first stop block 409 on the first transmission wheel is not contacted with the second protrusion 414 any more, and the first transmission wheel does not drive the transmission shaft of the upper cover of the toilet to rotate any more, thereby completing the opening of the upper cover of the toilet in the process.
In order to obtain an accurate rotation angle of the toilet upper cover, a limit switch is provided on the inner surface of the elliptical hole of the first elliptical member 403 and near the minor axis of the elliptical hole.
After the toilet upper cover is opened, the ray module of the infrared sensor 5 detects the gesture of the user, namely, whether the ray emitted by the infrared ray module is shielded by the gesture of the user is detected. If the ray emitted by the ray module is not shielded, the motor continues to rotate, and the toilet seat is opened; if the ray is detected to be blocked, the controller controls the motor to stop rotating and stops opening the toilet seat.
The process of opening the toilet seat by the motor is specifically the process of driving the transmission shaft of the toilet seat by the motor to rotate for the next 90 degrees. During the next 90 ° rotation, the second stopper 410 of the second wheel 407 pushes the fourth protrusion at the fixed end of the toilet seat transmission shaft 42 to rotate, the toilet seat transmission shaft 42 rotates therewith, and simultaneously the third protrusion of the second dialing tooth rotates from the long axis position to the short axis position in the elliptical hole of the second elliptical member 404. The third protrusion gradually shrinks when rotating from the long axis position to the short axis position, and the third protrusion shrinks into the fixed end of the toilet seat transmission shaft 42 when the short axis position is reached, the fourth protrusion shrinks along with the first protrusion 413, when the toilet seat transmission shaft rotates 90 degrees, the second stop block 410 on the second transmission wheel is not contacted with the fourth protrusion any more, the second transmission wheel can not drive the toilet seat transmission shaft to rotate, and the toilet seat is opened in the process.
After the toilet seat is opened, if the ray emitted by the ray module detects that the ray is blocked, the infrared sensor 5 sends a toilet seat closing signal to the controller, the controller controls the motor 6 to rotate reversely, and the motor drives the toilet seat transmission shaft to rotate reversely by 90 degrees, so that the toilet seat closing action is executed.
When the distance measuring module of the infrared sensor 5 determines that the user leaves, the infrared sensor sends a closing signal to the controller, the controller sends a reverse rotation signal to the motor according to the received closing signal, and the motor drives the transmission shaft of the upper cover of the closestool to rotate reversely according to the received reverse rotation signal; the transmission shaft of the upper cover of the closestool closes the upper cover of the closestool.
Further preferably, when the toilet upper cover transmission shaft is subjected to reverse resistance in forward rotation or reverse rotation, the current of the motor is increased. When the current to the motor increases to a critical threshold, the toilet lid gear shaft rotates in the opposite direction. For example, if the toilet lid is subjected to excessive resistance (i.e. the toilet lid is manually blocked from opening) during the opening process, the current of the motor will suddenly increase, and when the current of the motor reaches a critical threshold, the toilet lid is closed. During the closing process of the toilet lid, if the toilet lid is subjected to an excessive resistance (closing of the toilet lid is artificially blocked), the current of the motor will suddenly increase, and when the current of the motor reaches a critical threshold, the toilet lid is opened.
According to the scheme, the intelligent closestool cover in the application adopts the single-motor structure to control the opening and closing of the closestool cover and the seat cushion respectively in a time-sharing mode, and compared with a double-motor intelligent closestool in the prior art, the intelligent closestool with the double motors has the advantages that the structural cost can be greatly reduced, and the power consumption is small.
Further, the smart toilet lid in the present application further includes a motor separation structure 9. The motor separation structure 9 is disposed between the motor and the outer end surface of the first wheel body 406, and one end of the motor separation structure is connected to the motor and the other end of the motor separation structure is fixedly connected to the outer end surface of the first wheel body 406. Fig. 5 is a schematic structural view illustrating a motor separating structure according to a preferred embodiment. As shown in fig. 5, the motor detaching structure 9 includes a coupling 901 and a flange structure 902. Wherein, one end of the coupler is connected with the motor, and the other end surface is provided with an annular array of wedge-shaped teeth. The end face of the flange plate structure 902 connected with the coupler is provided with an annular array of wedge-shaped grooves 903, the wedge-shaped teeth are engaged with the wedge-shaped grooves, and the other end face of the flange plate structure is fixedly connected with the outer end face of the first wheel body 406.
The motor separation structure is arranged on the intelligent closestool cover, so that when the maximum load of the motor is exceeded (for example, when the closestool upper cover/closestool ring is manually opened or closed) or no power supply exists, the motor and the transmission structure are automatically separated, the closestool upper cover and the closestool ring are manually opened and closed, and the closestool upper cover can be prevented from being damaged.
Fig. 6 is a schematic structural view of the first or second set of teeth shown in accordance with another preferred embodiment. As shown in fig. 6, an inclined plane structure 419 is further disposed at the second protrusion of the first dialing tooth (or the fourth protrusion of the second dialing tooth), and when the inclined plane structure drives the corresponding dialing tooth, the dialing tooth will be automatically compressed into the corresponding slot, so that when power is off or a person is required to manually open or close the toilet lid/toilet ring, the toilet lid can be manually opened or closed with a small force.
Further, the intelligent toilet lid in the present application further includes an armrest 7 disposed outside the transmission mechanism 4. Preferably, the infrared sensor 5 is mountable on the armrest 7. The male's stool and urine can be automatically distinguished through the detection of the infrared sensor 5 on the user's gesture. Meanwhile, in order to enable the closestool to meet the requirements of users more flexibly, a man/woman gear switch can be arranged on the handrail 7 to distinguish the man/woman gears. The household closestool or the male toilet closestool can be arranged at a male gear, and when the current gear is determined to be the male gear, the rotation signal sent to the motor by the controller is the rotation signal for opening the closestool upper cover and the closestool ring. The motor drives the transmission mechanism to rotate according to the received rotation signal, and the transmission mechanism rotates 180 degrees to sequentially open the upper cover and the toilet seat. The gear can be set for ladies in a domestic environment or in a toilet for women. When the current gear is determined to be the female gear, the rotation signal sent to the motor is the rotation signal for only opening the upper cover of the closestool. The motor drives the transmission mechanism to rotate 90 degrees according to the received rotation signal, namely, only the upper cover of the closestool is opened.
According to the technical scheme, the intelligent toilet lid in this application, the lifting and closing of closestool upper cover and closestool circle adopt infrared induction range finding and gesture induction's mode, can realize opening and closing alone of closestool upper cover and closestool circle, satisfy the use habit that stool and urine/man and woman are different, and be non-contact, be difficult to be infected with the bacterium, do benefit to user's health. Simultaneously, the intelligent closestool lid in this application still uses single motor timesharing control closestool upper cover and the opening and closing of closestool circle respectively, reduces substantially manufacturing cost, and the consumption reduces.
