Description

TECHNICAL FIELD

[0002] With the continuous improvement of people's health awareness, the concern for daily drinking water quality is increasing. As a common terminal water dispenser in families, offices and public places, one of the core functions of the intelligent water dispenser is to monitor the water quality in real time and accurately. At present, most of the intelligent water dispensers on the market use integrated water quality detection probes (such as TDS probes) directly installed in the main flow channel to reflect the water quality by detecting the total dissolved solids value in the water.

[0003] However, this detection method directly installed in the flowing waterway is affected by many factors, which affects the accuracy of the detection results. Since the TDS probe detection is significantly affected by temperature, the continuous flow of water will cause fluctuations in the surface temperature of the probe, which will interfere with the detection results. The attachment and deposition of bubbles, impurities and scale in the water on the probe will further affect the sensitivity of the probe, resulting in a monitoring function that is virtually useless.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Embodiments of the water quality monitoring device for intelligent water dispensers of the present invention, such as... Figures 1 to 10 As shown, it includes a fixed shell 100, a movable shell 200, a detection body 300, and a vibration mechanism.

[0034] The fixed housing 100 is connected to an inlet pipe 110 and an outlet pipe 120 on both sides respectively. A partition 130 is provided inside the fixed housing 100, which divides the fixed housing 100 into a temporary flow chamber 101 and a detection chamber 102.

[0035] The movable shell 200 is slidably installed on the fixed shell 100, and the temporary flow chamber 101 and the detection chamber 102 are selectively connected to the inlet pipe 110 and the outlet pipe 120.

[0036] The detection body 300 is disposed in the fixed shell 100 and includes a probe 310 extending into the detection chamber 102; the detection body 300 is existing technology and obtains water quality information by detecting the TDS value in the water.

[0037] The vibration mechanism includes vibration rods 410 parallel to the probe 310 and disposed on both sides of the probe 310. The vibration mechanism has a high-frequency low-amplitude vibration mode and a low-frequency high-amplitude vibration mode. Compared with the low-frequency high-amplitude vibration mode, the high-frequency low-amplitude vibration mode has a smaller amplitude and a higher vibration frequency of the vibration rods 410. When the temporary flow chamber 101 is connected to the inlet pipe 110 and the outlet pipe 120, the vibration mechanism is in the high-frequency low-amplitude vibration mode. When the detection chamber 102 is connected to the inlet pipe 110 and the outlet pipe 120, the vibration mechanism is in the low-frequency high-amplitude vibration mode, and the vibration rods 410 clean the probe 310 when they vibrate.

[0038] In use, the fixed housing 100 is placed in the water inlet pipe of the water dispenser, and the water inlet pipe 110 and the water outlet pipe 120 are respectively connected to the water inlet pipe of the water dispenser. Water enters from the water inlet pipe 110, flows through the fixed housing 100, and flows out from the water outlet pipe 120. During normal water intake, the movable housing 200 moves to connect the detection chamber 102 to the water inlet pipe 110 and the water outlet pipe 120, and the vibration mechanism is in a low-frequency, high-amplitude vibration mode. At this time, the probe 310 does not perform detection, and the vibration rod 410 cleans the probe 310 during vibration, reducing the adhesion of impurities in the water to the probe 310. After the preset working time, the movable shell 200 moves to connect the temporary flow chamber 101 to the inlet pipe 110 and the outlet pipe 120, and the vibration mechanism switches to a high-frequency, low-amplitude vibration mode. At this time, the water flow in the detection chamber 102 stops, preventing temperature fluctuations near the probe 310. The probe 310 begins to detect water quality, and simultaneously, the vibration rod 410 vibrates to reduce the adhesion of air bubbles on the probe 310, preventing air bubbles from affecting the detection results. After the detection is completed, the movable shell 200 moves again to connect the detection chamber 102 to the inlet pipe 110 and the outlet pipe 120, the vibration mechanism switches back to a low-frequency, high-amplitude vibration mode, and the probe 310 stops detecting.

[0039] By setting two chambers, a temporary flow chamber 101 and a detection chamber 102, within the fixed housing 100, and enabling the vibration mechanism to have two vibration modes, during testing, the temporary flow chamber 101 is connected to the inlet pipe 110 and the outlet pipe 120, without affecting the normal water flow, while the detection chamber 102 is sealed to prevent the water flow from affecting the temperature at the probe 310. Furthermore, the high frequency and small amplitude of the vibrating rod 410 disperse air bubbles near the probe 310, reducing their adhesion and impact on the test results. When not testing, the detection chamber 102 is connected to the inlet pipe 110 and the outlet pipe 120, allowing water to flush the probe 310. The vibrating rod 410 moves in a low-frequency, high-amplitude vibration direction to clean the probe 310, preventing impurities from depositing on the probe and affecting its water quality test results.

[0040] In this embodiment, the movable shell 200 is a frame structure without a lid or bottom, and its middle part slides through the fixed shell 100. Both sides of the movable shell 200 within the fixed shell 100 have connecting openings 210. The inner wall of the movable shell 200 is fitted against the two sides of the partition 130. The movable shell 200 moves in a direction perpendicular to the partition 130, and its movement has a first position and a second position. In the first position, the movable shell 200, together with the partition 130 and the fixed shell 100, closes the detection chamber 102, and the inlet pipe 110 and outlet pipe 120 communicate with the temporary flow chamber 101 through the connecting openings 210. In the second position, the movable shell 200, together with the partition 130 and the fixed shell 100, closes the temporary flow chamber 101, and the inlet pipe 110 and outlet pipe 120 communicate with the detection chamber 102 through the connecting openings 210. Specifically, a drive cylinder 140 is installed on the fixed housing 100, and the output shaft of the drive cylinder 140 is connected to the movable housing 200 to drive the movable housing 200 to reciprocate between the first position and the second position.

[0041] In this embodiment, the vibrating rod 410 is slidably mounted on the fixed shell 100 along its own axis and connected to the fixed shell 100 through the elastic element 411; an impeller 420 is rotatably arranged in both the temporary flow chamber 101 and the detection chamber 102. When water flows through the temporary flow chamber 101 or the detection chamber 102, the impeller 420 rotates and transmits the rotation to the vibrating rod 410 through the transmission unit, causing the vibrating rod 410 to move and reset under the action of the elastic element 411, thereby generating reciprocating movement along its own axis.

[0042] In this embodiment, the transmission unit includes a first gear 431, a second gear 432, and at least one transmission block 433. The transmission block 433 is slidably mounted on the fixed housing 100 in a direction perpendicular to the axis of the vibrating rod 410 and abuts against the vibrating rod 410 through an inclined surface. The first gear 431 and the second gear 432 are both rotatably mounted on the fixed housing 100 and mesh with each other. The first gear 431 is coaxial with the impeller 420 and fixedly connected. The axis of the second gear 432 is parallel to the axis of the vibrating rod 410. A sliding column 435 is provided at an eccentric position on the second gear 432. A sliding groove 436 perpendicular to its axis is provided on the transmission block 433. The sliding column 435 and the sliding groove 436 slide in cooperation, so that when the second gear 432 rotates, it drives the transmission block 433 to reciprocate along its axis, thereby pushing the vibrating rod 410 to move and allowing the vibrating rod 410 to intermittently reset under the action of the elastic member 411. Specifically, when the second gear 432 rotates, the sliding column 435 slides within the sliding groove 436, driving the transmission block 433 to reciprocate periodically. When the transmission block 433 moves towards the vibrating rod 410, it pushes the vibrating rod 410 towards the interior of the fixed housing 100 via the inclined surface. When the transmission block 433 moves away from the vibrating rod 410, the vibrating rod 410 moves away from the interior of the fixed housing 100 under the action of the elastic element 411, thereby causing the vibrating rod 410 to reciprocate along its axial direction. Due to installation position limitations, two transmission blocks 433 can also be provided. The two transmission blocks 433 are slidably installed on the fixed housing 100 in mutually perpendicular directions and are engaged by inclined surfaces. One transmission block 433 has its own sliding groove 436 to engage with the sliding column 435, and the other transmission block 433 abuts against the vibrating rod 410 via the inclined surface.

[0043] In this embodiment, the transmission unit connected to the impeller 420 in the transient cavity 101 is the first unit 440, and the transmission unit connected to the impeller 420 in the detection cavity 102 is the second unit 450. The diameter of the first gear 431 of the first unit 440 is larger than the diameter of the second gear 432, and the diameter of the first gear 431 of the second unit 450 is smaller than the diameter of the second gear 432. This results in the first unit 440 transmitting a small amplitude and high frequency of motion to the vibrating rod 410, while the second unit 450 transmitting a large amplitude and low frequency of motion to the vibrating rod 410. Specifically, when the diameter of the first gear 431 is larger than the diameter of the second gear 432, the second gear 432 rotates faster, resulting in a smaller movement amplitude of the transmission block 433 during rotation, thereby causing the vibration frequency of the vibrating rod 410 to be high and the amplitude to be small. Conversely, when the diameter of the first gear 431 is smaller than the diameter of the second gear 432, the rotation speed of the second gear 432 is slower, and the movement amplitude of the transmission block 433 is larger when it rotates, which in turn makes the vibration frequency of the vibrating rod 410 lower and the amplitude larger.

[0044] In this embodiment, the inclination of the inclined surface where the transmission block 433 of the first unit 440 abuts against the vibration rod 410 is less than that of the inclined surface where the transmission block 433 of the second unit 450 abuts against the vibration rod 410, so as to further increase the amplitude transmitted from the second unit 450 to the vibration rod 410.

[0045] In this embodiment, a cleaning sleeve 320 is provided over the probe 310. The cleaning sleeve 320 is in frictional contact with the probe 310 and can slide relative to the probe 310. The friction between the two allows the cleaning sleeve 320 to remain at any position outside the probe 310. Two baffles 321 are spaced apart along the axial direction of the probe 310 on the outer side of the cleaning sleeve 320. A retaining ring 412 is fixed to the outside of the vibration rod 410, and the retaining ring 412 is located between the two baffles 321. The distance between the two baffles 321 is greater than the travel distance of the vibration rod 410 in the high-frequency low-amplitude vibration mode and less than the travel distance of the vibration rod 410 in the low-frequency high-amplitude vibration mode. This allows the retaining ring 412 to reciprocate between the two baffles 321 when the vibration mechanism is in the high-frequency low-amplitude vibration mode; when the vibration mechanism is in the low-frequency high-amplitude vibration mode, the retaining ring 412 moves to abut against the baffles 321 and then drives the cleaning sleeve 320 to reciprocate relative to the probe 310 to clean the probe 310.

[0046] In operation, the water quality monitoring device for a smart water dispenser of the present invention has a fixed housing 100 installed in the water inlet pipe of the water dispenser, and the water inlet pipe 110 and the water outlet pipe 120 are respectively connected to the water inlet pipe of the water dispenser. Water enters from the water inlet pipe 110, flows through the fixed housing 100, and flows out from the water outlet pipe 120. During normal water intake, the movable housing 200 is in the second position, the detection chamber 102 is connected to the water inlet pipe 110 and the water outlet pipe 120, and the vibration mechanism is in a low-frequency, high-amplitude vibration mode. At this time, the probe 310 does not perform detection, and the vibration rod 410 vibrates at a large amplitude and low frequency to clean the probe 310, reducing the adhesion of impurities in the water to the probe 310. After the preset working time, the drive cylinder 140 extends, moving the movable shell 200 to the first position. The temporary flow chamber 101 connects to the inlet pipe 110 and the outlet pipe 120. The detection chamber 102 is sealed by the partition 130, the movable shell 200, and the fixed shell 100. The vibration mechanism switches to a high-frequency, low-amplitude vibration mode. At this time, the water flow in the detection chamber 102 stops, preventing temperature fluctuations near the probe 310. The probe 310 begins to detect water quality. Simultaneously, the vibration rod 410 vibrates at a high frequency and small amplitude to reduce the adhesion of air bubbles to the probe 310, preventing air bubbles from affecting the detection results. After the detection is completed, the drive cylinder 140 retracts, moving the movable shell 200 back to the second position, connecting the detection chamber 102 to the inlet pipe 110 and the outlet pipe 120. The vibration mechanism switches back to a low-frequency, high-amplitude vibration mode, and the probe 310 stops detecting.

[0047] The embodiments of the water quality monitoring system for intelligent water dispensers provided by the present invention include the aforementioned water quality monitoring equipment for intelligent water dispensers, and further include a display module for displaying the values ​​monitored by the probe 310. In some other embodiments, the water quality monitoring system for intelligent water dispensers also includes a timing module for periodically triggering the start of the drive cylinder 140, thereby enabling the detection body 300 to automatically and periodically detect water quality. Both the display module and the timing module are prior art, and their specific principles will not be elaborated further.

[0048] A water quality monitoring method for smart water dispensers, utilizing the aforementioned water quality monitoring equipment for smart water dispensers, includes the following steps:

[0049] S10, during normal operation, the movable shell 200 connects the detection chamber 102 to the water inlet pipe 110 and the water outlet pipe 120, and the vibration mechanism is in a low-frequency high-amplitude vibration mode.

[0050] S20, after the preset working time, the movable shell 200 moves to connect the temporary flow chamber 101 with the water inlet pipe 110 and the water outlet pipe 120, and the vibration mechanism switches to the high frequency low amplitude vibration mode, and the probe 310 detects the water quality in the detection chamber 102.

[0051] S30, after the test is completed, the movable shell 200 moves again to connect the test chamber 102 with the water inlet pipe 110 and the water outlet pipe 120, and the vibration mechanism switches to the low frequency high amplitude vibration mode.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
