Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water purifiers, and in particular to a maintenance-free water quality detection device for water purifiers. Background Art
[0002] A water purifier can filter tap water and provide people with cleaner and even drinkable pure water.
[0003] In order to filter tap water, a filter element is usually installed in the water purifier, and the filter element is a consumable item and needs to be replaced. The filter element in the water purifier is mostly replaced according to the use cycle, but due to the high frequency of use of some water purifiers or filter element damage, the water quality may not meet the standard. Therefore, water quality testing is required to facilitate the replacement reminder of the filter element.
[0004] The water quality of a water purifier can be tested by manual sampling or online direct testing. Manual sampling is cumbersome, wastes manpower, and is not timely enough. Online direct testing requires the water quality detection sensor to maintain real-time contact with the water flow. Although problems can be discovered in a timely manner, the water quality detection sensor is easily covered with scale due to long-term immersion in the water flow, which affects the accuracy of the test. The water purifier needs to be unpacked for cleaning and maintenance, and the maintenance cost is high, which needs to be improved. Utility Model Content
[0005] The utility model aims to provide a maintenance-free water quality detection device for a water purifier, so as to realize online detection of the water quality of the water purifier and reduce the maintenance frequency.

[0008] Wherein, the diameter of the leakage hole is smaller than the inner diameter of the sampling tube.
[0009] Wherein, the diameter of the leakage hole is 3-5 mm.
[0010] Wherein, an air inlet hole is arranged on the top of the detection box.
[0011] Wherein, a dustproof net is arranged in the air inlet.
[0012] Wherein, a sewage pipe joint is arranged at the bottom of the leakage hole.
[0013] Wherein, a liquid level sensor is arranged on the detection box, and the liquid level sensor is connected to the controller.
[0014] Wherein, the detection box is provided with a second pipe joint connected to the sampling tube.
[0015] The beneficial effects of the utility model include: a maintenance-free water quality detection device for a water purifier, a controller that can open the solenoid valve at a fixed time, and introduce part of the water flow passing through the water purification pipe into the detection box through the sampling tube, so as to realize the immersion of the water quality detection sensor and the online detection of the water quality, and the water flow in the detection box can be slowly discharged through the leakage hole, which will not affect the detection work of the water quality detection sensor, but also avoid the problem of the water quality detection sensor being immersed for a long time, reduce scale, and can maintain the cleanliness of the water quality detection sensor for a longer time, which is beneficial to improve the detection accuracy and reduce the maintenance frequency. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0017] Combine the following Figure 1 The technical solution of the utility model is further illustrated by specific embodiments.
[0018] like Figure 1 The maintenance-free water quality detection device for a water purifier shown includes: a water purification pipe 7, a sampling tube 11, a controller 5, a solenoid valve 9, a water quality detection sensor 2 and a detection box 1. The water purification pipe 7 is arranged in the water purifier. The water purification pipe 7 can be connected between the filter and the faucet to deliver the filtered pure water to the faucet for easy use.
[0019] The water purification pipe 7 is provided with a first pipe joint 8, and the sampling pipe 11 is provided between the first pipe joint 8 and the detection box 1. In this embodiment, the detection box 1 is provided with a second pipe joint 12 connected to the sampling pipe 11, which is convenient for assembly. The solenoid valve 9 is connected in series to the sampling pipe 11. When the solenoid valve 9 is opened, part of the water flow passing through the water purification pipe 7 is introduced into the detection box 1 through the sampling pipe 11 to realize online sampling.
[0020] The water quality detection sensor 2 is arranged on one side or the bottom of the detection box 1, and the water quality detection sensor 2 is connected to the controller 5 to send a signal. Figure 1 As shown, the water flow in the detection box 1 immerses the water quality detection sensor 2, making it convenient for the water quality detection sensor 2 to perform water quality detection.
[0021] In this embodiment, the controller 5 is connected to the electromagnetic valve 9, and the electromagnetic valve 9 is automatically opened at a fixed time to guide the water flow into the detection box 1 for real-time online detection. The controller 5 can be a single-chip microcomputer, which is low in cost and easy to operate. In order to ensure that the sampled water flow immerses the water quality detection sensor 2, a liquid level sensor 4 is provided on the detection box 1. The liquid level sensor 4 is connected to the controller 5 to perform liquid level detection and control the electromagnetic valve 9 to close after the liquid level reaches the standard, thereby saving water.
[0022] After the detection is completed, the detection box 1 needs to be emptied. A drainage hole 10 is arranged at the bottom of the detection box 1. In the present embodiment, the diameter of the drainage hole 10 is smaller than the inner diameter of the sampling tube 11, so that the water in the detection box 1 can flow out automatically, thereby avoiding the problem of the water quality detection sensor 2 being immersed for a long time, reducing scale, and maintaining the cleanliness of the water quality detection sensor 2 for a longer period of time, which is beneficial to improving the detection accuracy and reducing the maintenance frequency.
[0023] The diameter of the drainage hole 10 is 3-5 mm, and the hole diameter is small, which controls the flow rate and avoids the problem that the water flow is quickly emptied and the detection cannot be completed. In this embodiment, a sewage pipe joint 3 is set at the bottom of the drainage hole 10, and the sewage tank of the water purifier can be connected to the outside through the pipeline.
[0024] like Figure 1 As shown, an air inlet 6 is provided on the top of the detection box 1 to replenish air, avoid negative pressure problems in the detection box 1, and ensure that the water in the detection box 1 flows downward through the leakage hole 10. In this embodiment, a dustproof net is provided in the air inlet 6 to prevent dust from falling into the detection box 1 through the air inlet 6 and keep the detection box 1 clean.
[0025] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
