Description

Technical Field

[0001] The invention belongs to the technical field of smart toilets, and in particular relates to a urine detector for a smart toilet. Background Art

[0002] With the rapid economic development, the increase of people's income and the increasing attention of consumers to the quality of life, smart sanitary ware has entered more and more families. As a typical representative, the smart toilet is becoming more and more popular in places such as homes and high-end hotels due to its health, comfort, cleanliness and hygiene.

[0003] Urine is a waste product produced by the kidneys filtering blood. It contains various metabolic byproducts. Urine testing can reveal various diseases in the urinary system and endocrine system and various problems in metabolism-related systems. Urine testing includes routine urine analysis, urine formed element testing (such as urine red blood cells, white blood cells, etc.), protein component quantitative determination, urine enzyme determination, etc. It is a routine examination method for physical health status. Urine testing is of great value in clinical diagnosis, judgment of efficacy and prognosis.

[0004] Urine testing first requires that the person being tested collects part of their urine during urination at the best time, and then sends it to the relevant department for special testing. The disadvantages of this method are that the container is easily contaminated when collecting urine; it is also easy to make mistakes during the urine transfer process, resulting in distorted test results, and each time you need to go to the hospital to register and queue up.

[0005] In order to detect urine at any time and thus understand one's own health condition, the intelligent toilet integrated urine detection function has become a research hotspot for intelligent toilet functions. Chinese invention patent application CN109826292A discloses an intelligent toilet for urine detection, including a toilet body, a toilet seat is provided on one side of the top of the toilet body, a toilet cover is provided at the bottom of the toilet seat, an infrared sensor is provided on one side of the toilet cover, a water tank is provided on the other side of the top of the toilet body, a display screen is provided on the top of the water tank, a urine detector is provided on the bottom of the water tank, a sampler is provided on one side of the urine detector that runs through the toilet body, a controller is provided at the bottom of one side of the toilet body, and the controller is electrically connected to the control panel. The infrared sensor is set to sense the user's use, and the controller controls the rotation of the motor to replace the measured test paper, collects urine through a retractable urine collection device, and detects urine through the urine detector, and displays the detection structure through the display screen, which is simple and convenient to operate, and is convenient for users to conduct urine detection in time and understand their own physical condition. The shortcomings of this device are that its structure and functions are too simple, its degree of automation is low, and it cannot meet the urine detection needs of smart toilets.

After the urine test paper 8 is loaded into the test paper filling port 12, the test paper motor 14 is started, and the test paper motor 14 drives the friction wheel 16 to rotate to drive the urine test paper 8 to be loaded into the urine detection chamber 7.

[0056] Compare with Figure 6-9 , the structure of the test paper ejection mechanism of the present invention is:

[0057] A test paper ejection chamber 30 connected to the urine detection chamber 7 is arranged above the sleeve 2, a third rotating shaft 31 is arranged between the test paper ejection chamber 30 and the urine detection chamber 7, a baffle 32 is arranged on the third rotating shaft 31, and the baffle 32 separates the test paper ejection chamber 30 from the urine detection chamber 7. When the urine detection test paper 8 is loaded, the baffle 32 is located in a vertical position to prevent the urine detection test paper 8 from moving excessively when loaded. When the urine detection test paper 8 is ejected, the baffle 32 is rotated around the third rotating shaft 31 by the impact force of the urine detection test paper 8, the baffle 32 is opened, and the urine detection test paper 8 is ejected.

[0058] A test paper ejection mechanism is provided below the urine detection chamber 7, including an ejection rod 18 composed of two parallel branch rods connected to each other, a pair of inward clamping heads 19 are provided at the front end thereof, and a pair of upward curved hooks 20 are provided at the rear end thereof, the curved hooks 20 move in the urine detection chamber 7, and the inner side thereof is in contact with and connected to the rear end surface of the urine detection paper 8 in the urine detection chamber 7, a first spring mounting seat 21 is provided on the ejection rod 18, a second spring mounting seat 22 arranged opposite to the first spring mounting seat 21 is fixed in the housing 1, the second spring seat 22 is located at the rear side of the first spring seat 21, and the first spring mounting seat 21 and the second spring mounting seat 22 are connected to each other. A spring is arranged between the ejection rod 18, and the ejection rod 18 is driven by the test paper motor 14 to move backward to compress the spring. A second gear 25 is sleeved on the first rotating shaft 15 of the test paper motor 14, and a third gear 26 is meshed on the front side of the second gear 25.

[0067] A test paper guide groove 39 is provided at the rear side of the test paper filling port 12 to facilitate the insertion of the test paper.

[0068] A photoelectric detector is provided on the housing 1 corresponding to the front end of the urine test strip 8 to detect whether the urine test strip 8 is properly loaded.

[0069] A Hall detector is disposed on the housing 1 corresponding to the second rotating shaft 27 to detect whether the ejection mechanism is completely disengaged from the gear.

[0070] Rollers 40 are disposed on both sides of the ejection rod 18 to reduce friction when the ejection rod 18 moves.

[0071] Compare with Fig.10 A rack guide plate 41 is disposed above the first rack 10. A fifth gear 42 is meshed between the second gear 25 and the third gear.
