Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-6 , a water quality detection device for drinking water equipment, including a water dispenser body 1, a top cylinder 2 is provided in the water storage tank at the upper end of the water dispenser body 1, an inner shell 4 is fixedly connected to the middle of the inner top wall of the top cylinder 2, an electric push rod 5 is fixedly installed inside the inner shell 4, a TDS water quality detection probe 6 is fixedly connected to the lower end of the electric push rod 5, a water sealing cylinder 7 is slidably connected to the outer side of the inner shell 4, a first sleeve 8 is fixedly connected to the inside of the left and right ends of the TDS water quality detection probe 6, the first sleeve 8 is slidably connected to the first clamp 9 at one end away from the TDS water quality detection probe 6, a first spring 10 is provided between the first clamp 9 and the first sleeve 8, and a card groove 11 is provided on the left and right inner walls of the water sealing cylinder 7 near the lower side. When the water in the bottled water is not drunk for a long time, the user can drink it. By opening the electric push rod 5, the TDS water quality detection probe 6 is driven to descend. During this process, since the force exerted by the second spring 14 on the second clamp 13 is greater than the force exerted by the first spring 10 on the first clamp 9, the water sealing cylinder 7 remains stationary when the TDS water quality detection probe 6 descends. When the first clamp 9 descends to the slot 11, the rebound effect of the first spring 10 can make the first clamp 9 and the slot 11 engage, and at the same time stop the TDS water quality detection probe 6 from descending. At this time, the lower end probe of the TDS water quality detection probe 6 is at the lower side of the water sealing cylinder 7, which releases the sealing effect between the sealing plate 17 and the water sealing cylinder 7, so that the TDS water quality detection probe 6 can detect the purity of the current bottled water and evaluate the purity of the water quality.

[0023] See also Figure 2-Figure 4Water inlet grooves 3 are provided at the front and rear ends of the top tube 2 near the lower side, and the length of the water sealing tube 7 is greater than the length of the slot of the water inlet groove 3, which ensures the rationality of the structure and enables the water sealing tube 7 to block and close the water inlet groove 3.

[0024] See also Figure 3-Figure 5 , the end of the first clamp 9 away from the first spring 10 is fitted with the inner wall of the water sealing cylinder 7, the end of the first clamp 9 away from the first spring 10 is adapted to the card slot 11, the left and right inner walls of the water sealing cylinder 7 are fixedly connected with a second sleeve 12 near the upper side, and the second sleeves 12 are slidably connected with a second clamp 13 at one end thereof, and a second spring 14 is provided between the second clamp 13 and the second sleeve 12. The elastic force of the second spring 14 is greater than the elastic force of the first spring 10. When the TDS value of the water quality is detected to be higher than the set TDS value for safe drinking, it means that the current The bottled water has deteriorated due to being stored for a long time or for other reasons, that is, the test result is unqualified. In order to ensure the user's drinking water safety, the output end of the electric push rod 5 will continue to extend downward. At this time, due to the clamping effect between the first clamp 9 and the clamping groove 11, which is much greater than the reaction force of the second spring 14 on the second clamp 13, the TDS water quality detection probe 6 will drive the water sealing cylinder 7 to descend synchronously when it descends. When the water sealing cylinder 7 descends to the appropriate position, it can block the water inlet groove 3 on the top cylinder 2, thereby isolating the deteriorated water in the bucket and preventing people from accidentally drinking it and affecting their health.

[0025] See also Figure 3 , both ends of the inner shell 4 are provided with a slide groove 15, and the end of the second clamp 13 away from the second sleeve 12 is slidably connected to the inside of the slide groove 15. By sliding the second clamp 13 inside the slide groove 15, it can be avoided that the water sealing cylinder 7 causes the first clamp 9 and the slot 11 to be misaligned during the lifting process, affecting the use effect.

[0026] See also Figure 1-Figure 2 The lower end of the TDS water quality detection probe 6 is fixedly connected to a fixing rod 16 near the left and right sides, and the lower end of the fixing rod 16 is fixedly connected to a sealing plate 17, and the sealing plate 17 fits in with the inner wall of the water sealing cylinder 7, and a sealing ring 18 is provided at the outer ring of the sealing plate 17. When the TDS water quality detection probe 6 rises and resets, the water sealing cylinder 7 will also rise, and eventually return to the initial position by the blocking effect of the top cylinder 2. At the same time, the first clamp 9 and the card slot 11 are separated. When the TDS water quality detection probe 6 also rises to the initial position, the sealing plate 17 is fitted with the lower opening of the water sealing cylinder 7 to form a closed space, and the sealing effect between the sealing plate 17 and the water sealing cylinder 7 is further improved by the sealing ring 18, thereby avoiding the TDS water quality detection probe 6 being soaked in water and affecting the detection results, and at the same time, the service life of the TDS water quality detection probe 6 can be improved.

[0027] Working principle: When the water in the bottled water has not been consumed for a long time, the user can turn on the electric push rod 5 to drive the TDS water quality detection probe 6 to descend. During this process, since the force exerted by the second spring 14 on the second clamp 13 is greater than the force exerted by the first spring 10 on the first clamp 9, the water sealing cylinder 7 remains stationary when the TDS water quality detection probe 6 descends. When the first clamp 9 descends to the card slot 11, the rebound effect of the first spring 10 can make the first clamp 9 and the card slot 11 engage, and at the same time stop the TDS water quality detection probe 6 from descending. At this time, the lower end probe of the TDS water quality detection probe 6 is under the water sealing cylinder 7, releasing the sealing effect between the sealing plate 17 and the water sealing cylinder 7, so that the TDS water quality detection probe 6 can detect the purity of the current bottled water and evaluate the purity of the water quality. When the TDS value of the water quality is detected to be higher than the set TDS value for safe drinking, it means that the current bottled water has deteriorated due to a long storage time or other reasons, that is, the test result is unqualified. In order to ensure the user To ensure the drinking water safety of the users, the output end of the electric push rod 5 will continue to extend downward. At this time, due to the clamping effect between the first clamp 9 and the clamping groove 11, which is much greater than the reaction force of the second spring 14 on the second clamp 13, the TDS water quality detection probe 6 will drive the water sealing cylinder 7 to descend synchronously when it descends. When the water sealing cylinder 7 descends to an appropriate position, it can block the water inlet groove 3 on the top cylinder 2, thereby isolating the deteriorated water in the bucket and preventing people from drinking it by mistake and affecting their health. Furthermore, when the TDS water quality detection probe 6 rises and resets, , the water sealing cylinder 7 will also rise, and eventually return to its initial position due to the blocking effect of the top cylinder 2. At the same time, the first clamp 9 and the card slot 11 are separated. When the TDS water quality detection probe 6 also rises to its initial position, the sealing plate 17 and the lower opening of the water sealing cylinder 7 are fitted together to form a closed space. The sealing effect between the sealing plate 17 and the water sealing cylinder 7 is further improved by the sealing ring 18, thereby avoiding the TDS water quality detection probe 6 being soaked in water and affecting the detection results. At the same time, the service life of the TDS water quality detection probe 6 can be improved.
