This application is a national stage of International Application No, PCT/CN2016/103191, filed Oct. 25, 2016, which claims the benefit and priority of Chinese Patent Application No. 201610305770.6, filed May 10, 2016, both of which are incorporated herein by reference in their entireties.
The present invention relates to the field of household health care or medical instrument, and more particularly, to a urine testing device and a smart toilet comprising same.
With the improvement of people's life demands, smart toilets are increasingly favored by the consumer. Currently, the smart toilets generally have the functions of cleaning, heating, sterilizing, or the like, but rarely have the urine testing function. Most of the existing urine testing devices are large medical instruments. During testing, the test paper is usually vertical to a pushing direction of a machine, a mechanical device pushes the test paper below a sample adding needle, the sample adding needle moves in a direction parallel to the test paper and dropwise adds samples, and then the mechanical device continues to push the test paper to a photoelectric detection position. A photoelectric probe moves in a direction parallel to the test paper and reads the results, and the mechanical device continues to push the test paper to a waste paper box. A system designed in this way has a very fast testing speed, but is not compact enough in structure, and has a larger space volume, which is not suitable to an occasion such as the smart toilet, which needs a compact structure, has heavy environmental humidity, and does not need fast testing speed.
One object of the present invention is to provide a urine testing device that has a small volume and a compact structure, is easy in installation and reliable in operation, and is more suitable for being installed in a smart toilet for use.
Another object of the present invention is to provide a smart toilet containing the urine testing device above.
In order to achieve the objects above, the following technical solutions are adopted in the present invention.
A urine testing device comprises a base, and a paper feeding module, a sample adding module and a testing module installed on the base and compactly arranged in a linear form from left to right, wherein: the paper feeding module comprises a test paper box, a lifting mechanism, and a pushing mechanism, a horizontal paper leakage groove is disposed at a bottom of the test paper box, and is used for receiving a bottommost piece of test paper which drops down by dead weight; the lifting mechanism is used for lifting and descending the test paper box to reveal or seal the paper leakage groove; the pushing mechanism is used for pushing out the test paper from the paper leakage groove and delivering the test paper to the sample adding module and the testing module; the sample adding module is used for dropwise adding urine to be tested on the test paper; and the testing module is used for testing the test paper added with the sample to obtain a urine testing result.
As a further improvement, the base is an integrated base, the base is respectively provided with an installation area for the paper feeding module, an installation area for the sample adding module and an installation area for the testing module, the installation area for the paper feeding module is provided with a containing cavity for installing the test paper box, a paper guide table is disposed at a right side of the containing cavity, and a test paper translation channel on the base is disposed at a right side of the paper guide table.
A bottom of the containing cavity is provided with a groove used for embedding the paper leakage groove, and an opening of the groove is provided with a sealing gasket for sealing the paper leakage groove.
The lifting mechanism comprises a first motor and a lifting snap table, the lifting snap table is installed in the containing cavity, the test paper box is snap-fit into the lifting snap table, and the first motor is connected to the lifting snap table and drives the lifting snap table to lift and descend, so as to drive the test paper box to lift and descend.
The pushing mechanism comprises a second motor, a pulling rod connected to the second motor, a third motor, and a screw rod connected to the third motor, the second motor is fixedly installed in a platform, the platform is sheathed on the screw rod and is internally provided with an internal thread matched with the screw rod, when the third motor drives the screw rod to rotate, the platform translates along the screw rod to drive the pulling rod to translate, the second motor is used for driving the pulling rod to an initial position or a working position, and the working position of the puling rod is aligned with the paper leakage groove.
The sample adding module comprises a fourth motor and a sample adding needle, the sample adding needle is used for being connected to a sample feeder, and the fourth motor is connected to the sample adding needle and drives the sample adding needle to move to a sample adding position or a cleaning position.
The sample feeder comprises a liquid inlet tube and a plunger pump, the liquid inlet tube is connected to the sample adding needle, the plunger pump is used for being respectively connected to a urine-collecting pipeline and a cleaning pipeline; during testing, the sample adding needle moves to the sample adding position, and the plunger pump is used for pumping the urine to be tested from the urine-collecting pipeline to the sample adding needle through the liquid inlet tube; and after testing, the sample adding needle moves to the cleaning position, and the plunger pump is used for pumping a cleaning fluid from the cleaning pipeline to the sample adding needle through the liquid inlet tube.
The testing module comprises a photoelectric probe detector, the photoelectric probe detector comprises a support installed on the base and multiple sets of photoelectric probes disposed in the support side by side, and each set of photoelectric probes is used for correspondingly testing one testing area on the test paper to be tested.
The testing module further comprises a fifth motor, the fifth motor is connected to the photoelectric probe detector and drives the photoelectric probe detector to move to a calibrating position, a testing position or a test paper recycling position, and a separable test paper recycling box is disposed below a position of the base corresponding to the test paper recycling position of the photoelectric probe detector.
A smart toilet comprises the urine testing device.
By adopting the technical solutions above, the present invention at least has the following advantages.
(1) Since the test paper box provided with the horizontal paper leakage groove at the bottom thereof is used, and matched with the lifting mechanism and the pushing mechanism, the horizontally placed test paper leaks out automatically by dead weight, and the test paper is easy to be movably pushed in a horizontal direction, thereby laying the foundation for the layout and working mode of the subsequent sample adding module and the testing module.
(2) Because the test paper is parallel to the pushing direction, the paper feeding module, the sample adding module and the testing module can be compactly arranged on the base in a linear form, so as to realize the modular setting with reasonable layout and high space utilization, and the urine testing process is finished at one time on the base from left to right; when each module implements the test, the movement range and the occupied space are small.
(3) Since the groove and the sealing gasket are disposed, sealing can be ensured when the lifting mechanism descends the test paper box, and the test paper box is not easy to be affected with damp and invalid during storage, so that when the test paper box is applied to the smart toilet, the test paper box is prevented from being affected by damp environment of toilet.
(4) Because the sample adding module is provided with the working position and the cleaning position of the sample adding needle, the cleaning is timely conducted after finishing the urine test, so as to avoid mutual effect between two tests.
(5) Since the photoelectric probe detector comprises multiple sets of photoelectric probes disposed side by side, when the test paper is translated below the photoelectric probe, the multiple sets of photoelectric probes work simultaneously, the test work of multiple test areas on the test paper can be finished at one time, comparing with traditional single-probe mobile scanning, the test efficiency is improved, the work mode of the detector is simplified, and the occupied space is saved.
