Description

[Technical field]

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

[0002] Smart toilets are common sanitary fixtures in people's daily lives, and their smart automated operation brings more convenience to users.

[0003] The main functions of a conventional smart toilet are flushing, drying, and an automatic opening and closing of the toilet lid. However, as people become more and more concerned about their health, excrement detection has also become one of the functions of a smart toilet. However, most of the detection mechanisms of conventional smart toilets are installed directly on the inside of the toilet lid and are directly exposed to the air, which may cause the detection mechanism to be damaged when the toilet is used or cleaned. In addition, if exposed to the outside for a long time, the surface of the detection mechanism will inevitably be contaminated by dust, which will affect the detection effect and make the overall aesthetics lacking. Therefore, in order to solve the problems existing in the prior art, a built-in excrement detection device for a smart toilet is proposed. Summary of the Invention [Problem to be solved by the invention]

[0004] The objective of the present invention is to address the deficiencies or shortcomings of the prior art by providing an excrement detection device for a built-in smart toilet, in which a detection device is installed on the base of the toilet cover, and the extension and contraction of the sensor is controlled by a stepping motor to detect excrement, and the detection device automatically extends to photograph the excrement and detect odor, and transmits the image and odor information to a data center, which detects excrement through the data center, thereby obtaining health data, and automatically returns to the base after detection is completed, which provides good protection for the detection device, makes the entire equipment more beautiful, and does not affect normal use. [Means for solving the problem]

[0005] In order to achieve the above objectives, the present invention adopts the following technical solutions: a toilet lid base 1 includes a toilet lid base 1, and an extension / retraction detection mechanism 2 is installed in the toilet lid base 1, the extension / retraction 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 installed in the gear box 22, 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 installed on the top of the gear box 22, the movable fixed frame 23 is actively connected to the guide rail 221, the detection sensor 24 is fitted to the tip of the movable fixed frame 23, a rack 231 is installed on 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 case and a collecting component 25, and the collecting component 25 includes a high-definition camera and an odor sensor.

[0006] Furthermore, a microphone 3 is installed on the toilet lid base 1.

[0007] Furthermore, two clamping plates 232 are symmetrically installed at the bottom of the movable fixed frame 23 . The clamping plates 232 have an L-shaped structure, and the bent portions of the clamping plates 232 are installed opposite each other to be aligned with the guide rails 221 .

[0008] Further, a rack groove 222 is formed in the guide rail 221 , and the drive gear 27 passes through the rack groove 222 and meshes with a rack 231 .

[0009] Furthermore, a rear end cover 233 is provided at the rear end of the movable fixed frame 23, and a conductor hole is provided in the rear end cover 233.

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

[0011] Furthermore, a passage hole 11 is provided in the toilet lid base 1 and is aligned with a detection sensor 24 .

[0012] The working principle of this invention is that the toilet cover base 1 is further equipped with a central processor and a wireless transmission module. When the user opens the toilet cover and uses it, the central processor starts the stepping motor 21, which rotates the driving gear 27 to move the rack 231. The movable fixed frame 23 and the detection sensor 24 extend stably from the fixed bracket 223 and extend into the toilet bowl through the passage hole 11. The collecting component 25 captures the excrement with a high-definition camera, and the captured image is transmitted to an external data center through the wireless transmission module, and the comparison distribution is performed. The central controller performs an analysis to obtain the user's health condition, and the microphone 3 collects audio signals during urination to determine whether the user is urinating, and if so, collects the urination time, and transmits the data to the data center for analysis of the urination situation. At the same time, the odor sensor collects odor information of feces and urine, which is also transmitted to the data center for comparison and analysis. After the user has finished excreting, the central controller controls the pump to flush the water, and during the cleaning, it starts the stepping motor 21 again to drive the detection sensor 24 to return it to its original position, thereby protecting the detection sensor 24. Effect of the Invention

[0013] By adopting the above technical solutions, the beneficial effects of the present invention are as follows: the detection device is installed on the base of the toilet cover, and the extension and contraction of the sensor is controlled by a stepping motor to detect excrement. The detection device automatically extends to photograph the excrement and detect odor, and transmits the image and odor information to a data center, which detects the excrement through the data center, thereby obtaining health data. After the detection is completed, the detection device is automatically returned to the base, which plays a good protective role for the detection device, makes the entire equipment more beautiful, and does not affect normal use.

[0015] Example 1 As shown in Figures 1 to 6, the technical solution adopted in the embodiment for implementing the present invention includes a toilet lid base seat 1 on which an expansion detection mechanism 2 is installed. In this embodiment, the toilet lid base seat is the mounting carrier for the expansion detection mechanism, and a central controller and a wireless transmission module are integrated and installed in the toilet lid base seat, which can be understood as enabling wired signal transmission through a signal line, and the central controller controls the expansion detection mechanism, and the expansion detection mechanism transmits the detection information to an external data center through the wireless or wired transmission module, so that the data center can carry out a comparative analysis of the user's excrement (feces or urine) and obtain further health status. Furthermore, by installing the expansion detection mechanism in the toilet lid base seat, the detection mechanism can be effectively protected without being exposed to the outside for a long time, and at the same time, the overall beauty of the toilet is enhanced, making it more clean and convenient.

[0016] More specifically, the extension / contraction 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 installed in the gear box 22. 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 installed on the top of the gear box 22. The movable fixed frame 23 is actively connected to the guide rail 221. The detection sensor 24 is fitted to the tip of the movable fixed frame 23. A rack 231 is installed on the bottom of the movable fixed frame 23. The rack 231 is connected to the driving gear 27. When the stepping motor is operated, the drive gear rotates to move the rack, thereby driving the movable fixed frame and detection sensor to expand and contract on the guide rail. A fixed bracket 223 is installed at the end of the guide rail 221, and the fixed frame 223 is fixed to the toilet lid base 1 and fits into the gap of the detection sensor 24. A through hole 11 is installed in the toilet lid base to align with the detection sensor 24. The fixed bracket also plays the role of fixing and guiding when detecting the expansion and contraction of the detection sensor, ensuring that it extends and returns smoothly into the toilet from the through hole.

[0017] The detection sensor 24 includes a fixed case and a collection component 25, which includes a high-definition camera and an odor sensor. The high-definition camera can photograph the shape of the excrement and what is attached to it. The odor sensor collects the odor of the excrement and transmits it to a data center for comparative analysis to obtain health data of the user. The built-in automatic telescopic detection mechanism not only brings the sensor closer to the excrement to obtain more accurate collection data, but also allows the sensor to be returned to the toilet lid to protect it after collection is completed.

[0018] More specifically, a microphone 3 is further installed on the toilet lid base 1, and during use, especially when an elderly person urinates, the microphone collects the urination time, and the data center determines the amount of urine excreted, thereby monitoring the urination status and better determining the health condition of the user.

[0019] More specifically, two clamping plates 232 are symmetrically installed at the bottom of the movable fixed frame 23. The clamping plates 232 have an L-shaped structure, and the bent portions of the clamping plates 232 are installed opposite each other to align with the guide rail 221. The clamping between the clamping plates and the guide rail enables the sensor to be moved by the movable fixed frame, and the sensor can be stably moved and expanded in accordance with the fixed bracket at the tip.

[0020] More specifically, a rack groove 222 is provided in the guide rail 221, and the driving gear 27 meshes with the rack 231 through the rack groove 222. In order to facilitate driving of the rack by the driving gear, a rack groove is provided in the guide rail, and the rack body meshes with the driving gear through the rack groove. When the driving gear rotates, the rack can be effectively driven to move the movable fixed frame, thereby moving the sensor to expand and contract.

[0021] More specifically, a rear end cover 233 is installed at the rear end of the movable fixed frame 23, and a conductor hole is installed in the rear end cover 233. The rear end cover supports the movable fixed frame and has a conductor hole installed thereon, and the connecting wire of the sensor comes out of the conductor hole and is connected to the control motherboard.

[0022] More specifically, the gearbox 22 has a gearbox cover plate 26 installed on the side away from the stepping motor 21, which fits into the gearbox to fix the drive gear and has a removable structure to facilitate replacement of the drive gear.

[0023] Example 2 Referring to Figure 7, the difference between this embodiment and embodiment 1 is that a fixed detection mechanism is adopted, which includes a detection sensor 24, a collection module 25 and a microphone 3, the detection sensor 24 is fixed to the toilet lid base 1, the collection module 25 is installed at the tip of the detection sensor 24 to detect excrement in the toilet, and the microphone 3 is installed on the toilet lid base 1 and positioned on the side of the detection sensor 24 to collect audio signals, the adoption of this method can reduce production costs and users can choose according to their actual needs.

[0024] The above does not limit the present invention, but is only used to describe the technical solutions of the present invention, and any other modifications or equivalent replacements made to the technical solutions of the present invention by those skilled in the art should all be included in the claims of the present invention, as long as they do not deviate from the spirit and scope of the technical solutions of the present invention.
