Description

Technical Field

[0001] This utility model relates to a filter detection device, and more particularly to a filter life detection device for micro-nano modules. Background Technology

[0002] Micro- and nanobubbles refer to bubbles with diameters ranging from tens of micrometers to hundreds of nanometers when they form. These bubbles fall between micrometer bubbles and nanobubbles and possess physical and chemical properties not found in conventional bubbles. Due to their unique physicochemical properties, micro- and nanobubbles show broad application prospects in many fields and have significant comparative advantages over traditional technologies.

[0003] Currently, micro and nano bubbles are used in various fields such as water treatment, agriculture, medical health, cleaning and environmental remediation. Generally, testing the lifespan of micro and nano bubble modules often requires testing the filter clogging of the module. The filter lifespan of micro and nano bubble modules has become a key factor affecting the quality of products in the above-mentioned fields.

[0004] In existing technologies, testing the filter life of micro-nano bubble modules in silty water environments typically requires repeatedly switching the water supply on and off without using pumps or valves to detect the impact of the current water quality on the filter screen. Therefore, this filter life test necessitates the testing equipment to provide intermittent water supply. However, most commercially available testing methods cannot completely eliminate the need for solenoid valves; they mostly rely on software to control the solenoid valves for intermittent water supply. This increases costs due to the need for software and circuit design, and it also fails to completely eliminate the influence of the solenoid valve itself on the degree of silty water blockage, leading to inaccurate results for the filter life test of the micro-nano module.

[0005] Therefore, to address the aforementioned problems, a more convenient and simpler tooling solution is needed to meet the requirements of intermittent water supply in the sediment test of micro-nano module filter screens, without requiring the design of software and electrical control circuits, and with higher detection accuracy and precision. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a filter life detection device for micro-nano modules with a simpler structural design and higher detection accuracy, in light of the above-mentioned existing technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a filter life detection device for micro-nano modules, characterized in that the detection device includes...

[0008] A base for mounting the micro / nano module to be tested, which includes a water inlet pipe;

[0009] The motion support is movably mounted on the base;

[0010] A drive assembly is used to control the motion support to perform vertical reciprocating motion along the base;

[0011] The micro-nano module to be tested has a slot channel on the water inlet pipe that is perpendicular to the axis of the water inlet pipe and is connected to the water inlet pipe.

[0012] The motion support includes a water channel support plate that can be inserted into the slot channel and moves vertically back and forth with the motion support. The water channel support plate has at least one water inlet that is compatible with and connected to the inner diameter of the water inlet pipe.

[0013] To ensure operational reliability, preferably, the motion support also includes a sliding rod. Correspondingly, the base is provided with a sliding sleeve that cooperates with the sliding rod to maintain the motion support's reciprocating motion in the vertical direction. Thus, the cooperation between the sliding sleeve and the sliding rod can achieve a guiding function and also ensure the reliability of the motion support's reciprocating motion.

[0014] For ease of structure and installation, the drive component preferably includes:

[0015] The base is fixed to the base.

[0016] A motor, mounted on a base, includes a rotatable output shaft;

[0017] A drive component, which is connected to the output shaft of the motor;

[0018] The motion support also includes a motion rod that can be linked with the drive component to achieve vertical reciprocating motion.

[0019] To further simplify the structure, and as a further preferred embodiment, the driving component is a cylindrical cam with a curved groove on its outer peripheral wall. Correspondingly, the moving rod is provided with a guide that can cooperate with the curved groove of the cylindrical cam to realize the vertical lifting and lowering action of the moving rod. Thus, by driving the rotation of the cylindrical cam with a motor, the rotational motion can be converted into the vertical reciprocating motion of the moving rod.

[0020] To ensure the reliability of continuous motion, preferably, there are two curved grooves, which are arranged vertically and horizontally along the outer peripheral wall of the cylindrical cam. Correspondingly, the guide is two protruding nails arranged vertically and horizontally, with the head of each protruding nail slidably embedded in the corresponding curved groove.

[0021] To facilitate assembly and enable the overall reciprocating linear motion of the motion support, preferably, the motion support also includes a top plate, a sliding rod, and a moving rod, wherein the sliding rod, the moving rod, and the water channel support plate are arranged parallel to each other, the top plate is arranged horizontally, and the sliding rod, the moving rod, and the water channel support plate are fixedly mounted on the top plate.

[0022] To improve the efficiency of water flow detection, preferably, the water channel support plate can have two water inlets spaced apart vertically, namely an upper water inlet and a lower water inlet. A sealing section is provided between the upper and lower water inlets to completely cut off the water inlet pipe of the micro / nano module. Furthermore, the size of the two water inlets is adapted to the inner diameter of the water inlet pipe of the nano module. Thus, during a single reciprocating motion, multiple water flow cycles can be achieved, obtaining multiple sets of detection data, greatly improving detection efficiency.

[0023] To achieve more precise control, preferably, the card slot channel and the water channel support plate are also equipped with sensor components that can detect the movement position of the water channel support plate.

[0024] As a further preferred embodiment, the sensor assembly includes a position signal transmitter and a position signal receiver. There is one position signal transmitter mounted on the water channel support plate. There are three position signal receivers, which are arranged sequentially from top to bottom on the slot channel at intervals. The interval between the three position signal receivers corresponds one-to-one with the interval between the two water inlets and the closed position on the water channel support plate.

[0026] Compared with the prior art, the advantages of this utility model are as follows: it eliminates the traditional solenoid valve, and can achieve stable intermittent water supply through mechanical structure alone. This not only avoids the influence of the solenoid valve itself on the degree of clogging of muddy water and improves the accuracy of the filter life detection of micro-nano modules, but also eliminates the need for software and electrical control board design, thereby saving production design and maintenance costs. The overall structure of the testing device is compact, simple, easy to assemble, and highly practical. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] like Figures 1 to 8 As shown in the figure, this embodiment discloses a testing device for testing the filter life of micro-nano modules. The testing device includes a base 1, a motion support and a drive assembly.

[0037] like Figure 1 , Figure 2 As shown, the micro-nano module 2 to be tested is mounted on the base 1. The micro-nano module 2 to be tested includes a water inlet pipe 21 (the arrows indicate the water inlet direction and the water outlet direction). A slot channel 3 is provided on the water inlet pipe 21, which is perpendicular to the axis of the water inlet pipe 21 and is connected to the water inlet pipe 21.

[0038] The drive assembly is used to control the motion support to perform vertical reciprocating motion along the base 1. The drive assembly includes a base 41, a motor 42 and a drive component. The base 41 is fixed on the base 1, the motor 42 is mounted on the base 41, and the motor 42 includes a rotatable output shaft 421. The drive component is connected to the output shaft 421 of the motor 42.

[0039] The motion support is movably mounted on the base 1. The motion support includes a top plate 51, a sliding rod 52, a motion rod 53, and a water channel support plate 54. The sliding rod 52, the motion rod 53, and the water channel support plate 54 are arranged parallel to each other, the top plate 51 is arranged horizontally, and the sliding rod 52, the motion rod 53, and the water channel support plate 54 are fixedly mounted on the top plate 51.

[0040] Therefore, a sliding sleeve 11 is provided on the base 1, which can cooperate with the sliding rod 52 to keep the moving bracket reciprocating in the vertical direction. The sliding sleeve 11 and the sliding rod 52 can achieve the guiding function and also ensure the reliability of the reciprocating motion of the moving bracket.

[0041] The moving rod 53 is linked with the driving component to achieve vertical reciprocating motion. The water channel support plate 54 can be inserted into the slot hole 31 of the slot channel 3 and move vertically reciprocating together with the moving bracket. The water channel support plate 54 has at least one water inlet that is compatible with and connected to the inner diameter of the water inlet pipe 21.

[0042] To simplify the structure, the driving component in this embodiment is a cylindrical cam 43 with a curved groove 431 on its outer peripheral wall. See [link to relevant documentation]. Figure 6 Correspondingly, the moving rod 53 is provided with a guide 531 that can cooperate with the curved groove 431 of the cylindrical cam 43 to realize the vertical lifting and lowering action of the moving rod 53. Thus, by driving the rotation of the cylindrical cam 43 through the motor 42, the rotational motion can be converted into the vertical reciprocating motion of the moving rod 53.

[0043] To ensure the reliability of continuous motion, there are two curved grooves 431, which are spaced vertically along the outer peripheral wall of the cylindrical cam 43. Correspondingly, the guide member 531 consists of two protruding pins arranged vertically and horizontally, with the head of each protruding pin slidably embedded in the corresponding curved groove 431. See [reference needed]. Figure 7 .

[0044] Alternatively, the drive component can also employ a crank-connecting rod mechanism that converts a rotating crank into linear motion. This type of crank-connecting rod mechanism is existing technology and is commonly found in the cylinder piston motion mechanism of automobile engines, and will not be described in detail in this application.

[0045] To improve the detection efficiency of water flow, the water channel support plate 54 of this embodiment has two water inlets spaced apart vertically, namely an upper water inlet 541 and a lower water inlet 543. A sealing position 542 is provided between the upper water inlet 541 and the lower water inlet 543 to completely cut off the water inlet pipe 21 of the micro-nano module. Furthermore, the size of the two water inlets is adapted to the inner diameter of the water inlet pipe 21 of the nano module.

[0046] Therefore, during a single reciprocating motion, water is alternately discharged from the upper water inlet 541 and the lower water inlet 543, allowing for multiple opening and closing of the water path and obtaining multiple sets of test data, greatly improving testing efficiency. The time it takes for the movement to pass through the intermediate closed section is the intermittent time. Alternatively, there can be only one water inlet, in which case the intermittent time will be doubled. Typically, the testing conditions for micro-nano modules used in sink products are 5-10 seconds of water flow interruption, while the testing conditions for micro-nano modules used in products with high water consumption, such as washing machines, are 30-60 seconds of water flow interruption. The number of water inlets and the interval distance of the closed positions 542 can be set according to the actual situation.

[0047] To make the control more precise, sensor components that can detect the movement position of the water channel support plate 54 are also provided on the card slot channel 3 and the water channel support plate 54 respectively.

[0048] To prevent leakage and improve the accuracy of test results, a sealing device 6 is also provided between the slot channel 3 and the water support plate 54 along the axial direction of the water inlet pipe 21. Figure 3 As shown, the sealing device 6 has an opening in the middle that can communicate with the water inlet pipe 21, and sealing soft rubber 61 is arranged symmetrically on both sides inside the sealing device 6. In this embodiment, the sealing device 6 is fixedly installed in the water inlet pipe of the micro-nano module 2 to be tested, and the position height of the sealing device 6 remains unchanged no matter how the water channel support plate 54 moves up and down in the vertical direction.

[0049] In this embodiment, the sensor assembly uses the on / off principle of an optocoupler structure to determine the specific position of the water channel support plate 54. Specifically, the sensor assembly includes a position signal transmitter 70 and a position signal receiver. There is one position signal transmitter 70, located on one side of the closed position 542 of the water channel support plate 54. There are three position signal receivers, arranged sequentially and at intervals from top to bottom on the slot channel 3, including a first position signal receiver 71, a second position signal receiver 72, and a third position signal receiver 73. (See [reference]). Figure 1 As shown, the spacing between the three position signal receivers is exactly the same as the spacing between the upper water inlet 541, the closed position 542 and the lower water inlet 543 on the waterway support plate 54.

[0050] like Figure 8 As shown, when the water inlet pipe 21 of the micro-nano module is in the cut-off state, when the position signal transmitter 70 on the water channel support plate 54 (located on one side of the closed position 542) corresponds exactly to the second position signal receiver 72 located in the middle of the slot channel 3, it indicates that the water channel is cut off. At this time, the water channel support plate 54 is in the initial position (restored position).

[0051] like Figure 4As shown, when the water inlet pipe 21 of the micro-nano module is connected, when the position signal transmitter 70 on the water channel support plate 54 (located on one side of the closed position 542) corresponds to the third position signal receiver 73 located at the bottom of the slot channel 3, it indicates that the water channel is connected. At this time, the water channel support plate 54 moves downward to the lowest position.

[0052] like Figure 5 As shown, when the water inlet pipe 21 of the micro-nano module is connected, when the position signal transmitter 70 on the water channel support plate 54 (located on one side of the closed position 542) corresponds exactly to the first position signal receiver 71 located on the upper part of the card slot channel 3, it indicates that the water channel is connected. At this time, the water channel support plate 54 moves upward to the highest position.

[0053] Therefore, by using the corresponding triggering relationship between the position signal transmitter 70 and different position signal receivers, the current movement position of the water channel support plate 54 can be determined. By controlling the speed of the motor 42, the frequency of the water channel support plate 54 moving up and down can be controlled to meet the intermittent water supply and de-flow test conditions of different products for micro-nano modules.

[0054] This embodiment eliminates the traditional solenoid valve, achieving stable intermittent water supply solely through mechanical structure. It avoids the influence of the solenoid valve itself on the degree of clogging by sediment, improves the accuracy of filter life detection for micro-nano modules, and the overall structure of the testing device is compact, simple, easy to assemble, and highly practical.
