Description

Technical Field

[0001] The invention relates to an excrement detection device for a built-in intelligent toilet, and relates to the technical field of intelligent toilet equipment. Background Art

[0002] Smart toilets are a common sanitary ware in people's daily lives, because their intelligent automatic operation can bring more convenience to users.

[0003] The main functions of existing smart toilets are flushing, drying, and sensing the opening and closing of toilet lids. However, as people pay more and more attention to health, the detection of excrement has also become one of the functions of smart toilets. However, the detection mechanism of existing smart toilets is mostly directly arranged on the inside of the toilet lid and directly exposed to the air. The detection mechanism may be damaged when using or cleaning the toilet. Moreover, the surface of the detection mechanism is inevitably contaminated with dust when exposed to the outside world for a long time, which affects the detection effect. In addition, the overall aesthetics is insufficient. Therefore, a built-in excrement detection device for smart toilets is proposed to solve the problems existing in the prior art. Summary of the invention

[0004] The purpose of the present invention is to address the defects or shortcomings in the prior art and provide an excrement detection device for a built-in smart toilet. The detection device is set on the base of the toilet cover and the extension and retraction of the sensor is controlled by a stepper motor to detect excrement. The detection device automatically extends to photograph and detect the odor of the excrement, and transmits the image and odor information to a data center. The excrement is detected by the data center to obtain health data. After the detection is completed, the detection device automatically returns to the base, which plays a good protective role for the detection device and makes the overall equipment more beautiful without affecting normal use.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: it includes a toilet cover base 1, on which a telescopic detection mechanism 2 is arranged, and the telescopic detection mechanism 2 includes a stepping motor 21, a gear box 22, a movable fixed frame 23, and a detection sensor 24. A driving gear 27 is arranged in the gear box 22, and the motor output shaft of the stepping motor 21 is connected to the driving gear 27 in the gear box 22. A guide rail 221 is arranged on the top of the gear box 22, and the movable fixed frame 23 is movably connected to the guide rail 221. The detection sensor 24 is socketed with the front end of the movable fixed frame 23, and a rack 231 is arranged at the bottom of the movable fixed frame 23, and the rack 231 is meshed with the driving gear 27. The detection sensor 24 includes a fixed shell and a collection component 25, and the collection component 25 includes a high-definition camera and an odor sensor.

[0006] Furthermore, a microphone head 3 is also provided on the toilet seat base 1.

[0007] Furthermore, two clamping plates 232 are symmetrically arranged at the bottom of the movable fixing frame 23 . The clamping plates 232 are L-shaped structures, and the bent parts of the clamping plates 232 are arranged to face each other and match the guide rails 221 .

[0008] Furthermore, a rack groove 222 is provided on the guide rail 221 , and the driving gear 27 passes through the rack groove 222 and meshes with the rack 231 .

[0009] Furthermore, a rear end cover 233 is provided at the rear end of the movable fixing frame 23 , and a wire hole is provided on the rear end cover 233 .

[0010] Furthermore, a gear box cover plate 26 is provided on the side of the gear box 22 away from the stepping motor 21 .

[0011] Furthermore, the toilet seat base 1 is provided with a through hole 11 matching the detection sensor 24 .

[0012] The working principle of the present invention is as follows: a central processing unit and a wireless transmission module are also integrated on the toilet lid base 1. When the user opens the toilet lid for use, the central processing unit starts the stepper motor 21 and drives the gear 27 to rotate, thereby driving the rack 231 to move. The mobile fixing bracket 23 and the detection sensor 24 are stably extended from the fixing bracket 223 and extend into the toilet through the through hole 11. The acquisition component 25 shoots the excrement through a high-definition camera, and the captured image is transmitted to an external data center through a wireless transmission module for comparative analysis, so as to obtain the user's health status. At the same time, the microphone 3 collects the sound signal during urination to determine whether urination is in progress. If urination is in progress, the urination duration is collected and the data is transmitted to the data center for analysis of the urination situation. The odor sensor will also collect feces or urine odor information at the same time, and also transmit it to the data center for comparative analysis. When the user finishes excreting, the central controller controls the water pump to flush. During flushing, the stepper motor 21 is started again to drive the detection sensor 24 back to its original position to protect the detection sensor 24.

[0013] After adopting the above technical scheme, the beneficial effects of the present invention are as follows: by setting the detection device on the base of the toilet lid and controlling the extension and retraction of the sensor through a stepper motor, the excrement is detected, the detection device automatically extends to shoot and detect the odor of the excrement, and transmits the image and odor information to the data center, and the excrement is detected by the data center to obtain health data. After the detection is completed, it automatically returns to the base, which plays a good protective role for the detection device and makes the overall equipment more beautiful without affecting normal use.

DETAILED DESCRIPTION

[0023] Example 1

[0024] See also Figure 1-Figure 6As shown, the technical solution adopted in this specific embodiment is: it includes a toilet cover base 1, and a telescopic detection mechanism 2 is arranged on the toilet cover base 1. In this embodiment, the toilet cover base is the installation carrier of the telescopic detection mechanism. The central controller and the wireless transmission module are integrated on the toilet cover base. It can be understood that wired signal transmission can also be performed through the signal line. The central controller controls the telescopic detection mechanism. When the telescopic detection mechanism transmits the detection information to the external data center through the wireless or wired transmission module, the user's excrement (feces or urine) is compared and analyzed in the data center to obtain the health status. The telescopic detection mechanism is arranged on the toilet cover base, which will not be exposed to the outside all the time, and can effectively protect the detection mechanism. At the same time, it also increases the overall aesthetics of the toilet and is easier to clean.

[0025] More specifically, the telescopic detection mechanism 2 includes a stepper motor 21, a gear box 22, a movable fixed frame 23, and a detection sensor 24. The gear box 22 is provided with a driving gear 27. The output shaft of the stepper motor 21 is connected to the driving gear 27 in the gear box 22. A guide rail 221 is provided on the top of the gear box 22. The movable fixed frame 23 is movably connected to the guide rail 221. The detection sensor 24 is sleeved with the front end of the movable fixed frame 23. A rack 231 is provided at the bottom of the movable fixed frame 23. The rack 231 is connected to the driving gear 27. When the stepper motor is working, the gear is driven to rotate and the rack is driven to move, thereby driving the movable fixed frame and the detection sensor to extend and retract on the guide rail. At the same time, a fixed bracket 223 is provided at the front end of the guide rail 221. The fixed bracket 223 is fixed on the toilet cover base 1 and is clearance-matched with the detection sensor 24. A through hole 11 is provided on the toilet cover base to match the detection sensor 24. The fixed bracket also plays a fixing and guiding role when the detection sensor is extended and retracted, ensuring that it can be smoothly extended from the through hole into the toilet and then retracted therefrom.

[0026] The detection sensor 24 includes a fixed shell and a collection component 25. The collection component 25 includes a high-definition camera and an odor sensor. The high-definition camera can capture the shape of excrement and the objects attached thereto. The odor sensor collects the odor of the excrement, transmits it to the data center for comparative analysis, and obtains the user's health data. The built-in automatic telescopic detection mechanism can not only bring the sensor closer to the excrement and obtain more accurate collection data, but also return it to the toilet cover to protect the sensor after the collection is completed.

[0027] More specifically, the toilet seat base 1 is also provided with a microphone head 3. During use, especially when the elderly urinate, the microphone head is used to collect the urination time, and the urine volume is determined by the data center, so that the urination situation can be monitored and the user's health condition can be better determined.

[0028] To be more specific, two clamping plates 232 are symmetrically arranged at the bottom of the movable fixed frame 23. The clamping plates 232 are L-shaped structures, and the bent parts of the clamping plates 232 are arranged opposite to each other and matched with the guide rail 221. The movable fixed frame drives the movement of the sensor by clamping the clamping plates and the guide rail, and the sensor can be stably telescopically moved in conjunction with the fixed bracket at the front end.

[0029] To be more specific, a rack groove 222 is provided on the guide rail 221, and the driving gear 27 passes through the rack groove 222 and meshes with the rack 231. In order to facilitate the driving of the rack by the driving gear, a rack groove is opened on the guide rail, and the rack body passes through the rack groove and meshes with the driving gear. When the driving gear rotates, it can effectively drive the rack to drive the movable fixed frame to move, thereby driving the sensor to extend and retract.

[0030] More specifically, the rear end of the movable fixing frame 23 is provided with a rear cover 233, and the rear cover 233 is provided with a wire hole. The rear cover supports the movable fixing frame and is provided with a wire hole. The connecting wires of the sensor pass through the wire hole and are connected to the control mainboard.

[0031] More specifically, a gear box cover 26 is provided on the side of the gear box 22 away from the stepper motor 21. The gear box cover 26 cooperates with the gear box to fix the driving gear, and the detachable structure facilitates the replacement of the driving gear.

[0032] Example 2

[0033] See also Figure 7 As shown, the difference between this embodiment and embodiment 1 is that a fixed detection mechanism is adopted, and the fixed detection mechanism includes a detection sensor 24, a collection component 25, and a microphone 3. The detection sensor 24 is fixed on the toilet cover base 1, and the collection component 25 is arranged at the front end of the detection sensor 24 to detect the excrement in the toilet. The microphone 3 is arranged on the toilet cover base 1, located on one side of the detection sensor 24, to collect the sound signal. The adoption of this solution can reduce the production cost, and the user can choose according to the actual needs.

[0034] The above description is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
