Description

Technical Field

[0001] The utility model relates to the technical field of toilet deodorization function testing, in particular to intelligent toilet deodorization function testing equipment. Background Art

[0002] With the development of science and technology, various designs to improve people's living conditions have emerged. As for toilets, they are now basically automatic flushing types, divided into two types: sitting toilets and squatting toilets. Sitting toilets have flushing toilets, and squatting toilets have toilet bowls. Their main structures are composed of toilet bowls, water tanks, and sewer pipes. When using them, the feces are defecated in the toilet bowl, and then the water stored in the water tank is used to flush the feces into the sewer pipes for drainage. When we use this kind of toilet, we will encounter such a problem. Since it takes a certain amount of time to defecate, during this period of time, feces and human intestinal gas will continue to emit a foul odor. Before flushing, These odors have nowhere to go and can only spread in the bathroom. Especially when the bathroom is too small or poorly ventilated, the odor will be more pungent. Sometimes the odor will even escape from the bathroom and enter the room. It usually takes a while to open the window for ventilation before it can dissipate. Therefore, the existing toilets are equipped with deodorizing filter modules to purify the air inside the bathroom. With the improvement of users' quality of life, users' demand for deodorizing toilets is increasing, and the requirements are also increasing accordingly. Therefore, the deodorizing filter modules of toilets need to be tested in the process of toilet production and sales.

[0003] The detection function of the existing toilet deodorization function testing equipment is relatively simple. When testing the deodorization filter module of the toilet, it can only detect the deodorization purification rate of the toilet. The existing toilet deodorization function testing equipment can guarantee the deodorization effect of a new toilet to a certain extent. However, after the toilet has been used for a certain period of time, the function of the deodorization filter module of the toilet will be damaged, resulting in a decrease in the deodorization effect of the deodorization filter module, and it is impossible to completely remove the odor in the bathroom, affecting the user's experience. If the deodorization filter module is damaged for too short a time, it will cause users to lose trust in the toilet manufacturer and reduce the repurchase rate. Utility Model Content

[0104] The working principle of the utility model is: when it is necessary to detect the long-term deodorization and purification effect of the deodorization and filtration module inside the toilet, take 100ml of ammonia solution, pour it into the storage container 22, place the container in the detection chamber 2 to volatilize (at any position), start the circulation fan 27, make the ammonia concentration at any position in the detection chamber 2 uniform, and use the ammonia detector 8 to test the concentration value change at each detection port until the concentration value reaches 0.4mg / ㎡ (0.5ppm), immediately cover the lid of the ammonia storage container 22 to stop volatilization, keep the circulation fan 27 rotating at the same time, place the prepared deodorization and filtration module to be tested in the closed detection chamber 2, start the deodorization and filtration module, and connect Continue to run for 48 hours (during operation, ensure that ammonia should pass through the deodorization filter module). When the ammonia concentration is insufficient, open the safety valve 32 to allow the ammonia in the ammonia bottle 31 to enter the detection chamber 2 through the ammonia inlet pipe 33 to replenish the ammonia concentration value and control the ammonia concentration value in the detection chamber 2 to be 0.32mg / ㎡±0.08mg / ㎡ (0.4ppm±0.1ppm). After running for 48 hours, take out the deodorization filter module and place it in the air at room temperature for 48 hours; then place the toilet body 1 equipped with the above-mentioned deodorization filter module on the rack 61. Before testing, start the flushing function of the flushing device of the toilet body 1, and flush the toilet 2 to 3 times. Then take 300ml of edible blended oil and pour it on the water seal in the toilet cavity so that the surface of the water seal is covered with edible oil. Place a gas collection sealing cover on the outside of the toilet body 1, cover the toilet body 1 with the gas collection sealing cover, and let the gas in the toilet water tank be smoothly discharged to the outside air through the sealing cover through the PVC pipe on the back of the sealing cover. Place a second ammonia detector 8b at the outlet of the pipe to check the ammonia concentration value after filtration at this position. Take 100ml of 2% ammonia solution again, pour it into an ammonia storage container 22 with a maximum height of 100mm and a diameter of 50mm, place the container in the closed test space to volatilize (at any position), and start the test. The circulating fan 27 in the closed test space is used to accelerate the uniformity of ammonia concentration at any position in the closed space, and the ammonia detector 8 is used to test the concentration value change at each detection port until the concentration value reaches 1.20 mg / ㎡ (1.5 ppm). The lid of the ammonia container is immediately covered to stop its volatilization, and the circulating fan 27 is turned off. The deodorization system of the deodorizing flushing device of the toilet body 1 is started, and the values ​​on the first ammonia detector 8a before filtration and the second ammonia detector 8b after filtration in the exhaust pipe are read at the same time, and the values ​​on the two ammonia gun detectors are recorded every 15 seconds until the recording is stopped after 8 minutes, completing the long-term test of the deodorization and purification effect of the deodorizing filter module.
