Detailed Implementation

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The dynamic demonstration device for water filtration principle in this embodiment of the invention includes a first sleeve 1, a second sleeve 2, a swing assembly 4, a sieve plate component 3, and a flipping component 5. The second sleeve 2 is sleeved inside the first sleeve 1. The sieve plate component 3 includes a first sieve plate 31 and a second sieve plate 32. The first sieve plate 31 is sleeved on the second sleeve 2 and is pivotally connected to the second sleeve 2. One end of the flipping component 5 is connected to the first sieve plate 31, and the other end of the flipping component 5 is connected to the second sieve plate 32. The flipping component 5 is adapted to rotate the second sieve plate 32 relative to the first sieve plate 31. The swing assembly 4 includes a connecting rod component and a swinging component. The swinging component is connected to the end of the first sieve plate 31 away from the second sieve plate 32. The connecting rod component is pivotally connected to the end of the first sieve plate 31 away from the second sieve plate 32. The swinging component is connected to the connecting rod component to drive the connecting rod 43 to move along the length direction of the first sleeve 1.

[0031] Specifically, such as Figures 1 to 8 As shown, the first sleeve 1 and the second sleeve 2 extend vertically. The second sleeve 2 is arranged inside the first sleeve 1, meaning there is a certain distance between the inner wall surface of the first sleeve 1 and the outer wall surface of the second sleeve 2. The first sieve plate 31 is fitted inside the second sleeve 2. A preset gap can be provided between the outer circumferential surface of the first sieve plate 31 and the inner wall surface of the first sleeve 1, thereby facilitating the vibration of the first sieve plate 31 in the vertical direction. One end of the flipping component 5 is connected to the first sieve plate 31, and the other end of the flipping component 5 is connected to the second sieve plate 32. During the water filtration demonstration, the flipping component 5 makes the upper surfaces of the first sieve plate 31 and the second sieve plate 32 lie on the same plane.

[0032] The lower end of the swing component is connected to the ground, and the driving end of the swing component is connected to the lower end of the connecting rod component. The swing component causes the connecting rod component to move in the vertical direction. The connecting rod component is pivotally connected to the first screen plate 31. The swing component moves the connecting rod component in the vertical direction.

[0033] The first sieve plate 31 and the second sieve plate 32 are provided with sieve holes, which are arranged at intervals around the circumference of the first sieve plate 31 and the second sieve plate 32.

[0034] During the water filtration demonstration, the flipping component 5 brings the upper surfaces of the first screen plate 31 and the second screen plate 32 to the same plane, and the swinging component causes the connecting rod 43 to swing vertically. At this time, the filter ball and the impurity ball roll on the first screen plate 31 and the second screen plate 32. The radial dimensions of the filter ball and the impurity ball are different; for example, the radial dimension of the impurity ball is larger than that of the filter ball. Consequently, the filter ball passes through the screen holes, while the impurity ball cannot.

[0035] After the water filtration demonstration is completed, the flipping component 5 flips the second screen plate 32 relative to the first screen plate 31. At this time, the swinging component causes the first screen plate 31 to rotate relative to the second screen plate 32, and the swinging component causes the end of the first screen plate 31 away from the second screen plate 32 to tilt upward, thereby facilitating the discharge of impurity balls.

[0036] The dynamic demonstration device for water filtration principle in the embodiment of the present invention, by setting a flipping component 5, can flip the second screen plate 32 relative to the first screen plate 31, so as to facilitate the discharge of the filtered impurity balls. The swinging component is adapted to tilt the first screen plate 31 relative to the second sleeve 2, so that the first screen plate 31 is tilted relative to the second sleeve 2, and then the impurity balls on the first screen plate 31 flow to the position after the second screen plate 32 is flipped under the action of gravity, so as to facilitate the discharge of impurity simulation and facilitate subsequent use.

[0037] In some embodiments, the flipping component 5 includes a first bracket 51, a second bracket 52 and a first driving member 53. One end of the first bracket 51 is connected to the first driving end of the first driving member 53, the second driving end of the first driving member 53 is connected to one end of the second bracket 52, the other end of the second bracket 52 is connected to the second sieve plate 32, and the other end of the first bracket 51 is connected to the first sieve plate 31.

[0038] Specifically, such as Figures 1 to 8 As shown, the first bracket 51 is connected to the first driving end of the first driving member 53, and the second bracket 52 is connected to the second driving end of the first driving member 53. The first bracket 51 is connected to the first sieve plate 31, and the second bracket 52 is connected to the second sieve plate 32. The first driving member 53 can open the first driving end. Since the first sieve plate 31 is sleeved on the second sleeve 2, opening the first driving end will eventually cause the second sieve plate 32 to flip relative to the first sieve plate 31.

[0039] Alternatively, the first driving member 53 can activate the second driving end to flip the second screen plate 32, thereby discharging the impurity balls; or, the first driving member 53 can activate both the first and second driving ends, causing the second screen plate 32 to rotate relative to the first screen plate 31, facilitating the discharge of the impurity balls.

[0040] Furthermore, the second flipping component 5 can be located below the first sieve plate 31 and the second sieve plate 32. The lower end of the first sieve plate 31 is connected to the upper end of the first support 51, and the lower end of the second sieve plate 32 is connected to the upper end of the second support 52. The first driving end of the first driving component 53 is connected to the first support 51, and the second driving end of the first driving component 53 is connected to the second support 52. The first driving component 53 causes the second sieve plate 32 to flip downward, thereby making it easier for the impurity balls to be discharged.

[0041] It should be noted that the first driving component 53 can be a servo motor, or the first driving component 53 can be other existing components, such as a servo motor.

[0042] In some embodiments, there are multiple sieve plate components 3, which are arranged at intervals along the length of the first sleeve 1. Each sieve plate component 3 has multiple sieve holes in its circumferential direction, and the size of the sieve holes on the multiple sieve plate components 3 gradually decreases along the direction closer to the ground.

[0043] There are multiple flipping components 5, and each flipping component 5 is connected to a corresponding screen plate component 3.

[0044] Specifically, such as Figures 1 to 8 As shown, the first sieve plate 31 and the second sieve plate 32 are each provided with multiple sieve holes, and the radial dimensions of the sieve holes on the multiple sieve plate components 3 in the vertical direction gradually decrease from top to bottom. That is, in the vertical direction, the size of the sieve holes on the sieve plate component 3 with a higher height is larger than the size of the sieve holes on the sieve plate component 3 with a lower height, thereby better simulating the water filtration process, facilitating popular science about the water stratification filtration process, and improving the teaching demonstration effect.

[0045] It is understandable that the first sleeve 1, the second sleeve 2, and the sieve plate component 3 can all be made of transparent material, which facilitates the improvement of teaching effectiveness.

[0046] It should be noted that the radial dimensions of the multiple impurity balls are different, but the radial dimension of the sieve holes on the bottommost sieve plate component 3 is larger than the radial dimension of the filter ball, and the radial dimension of the sieve holes on the bottommost sieve plate component 3 is smaller than the filter size of the smallest impurity ball.

[0047] In some embodiments, the dynamic demonstration device for the water filtration principle further includes a ball-dropping assembly 6 and a lifting component 7, wherein the ball-dropping assembly 6 is connected to the lifting component 7.

[0048] The ball-dropping assembly 6 includes a ball-dropping component 61 and a ball-collecting component 62. The ball-dropping component 61 is sleeved on the second sleeve 2. The ball-collecting component 62 and the lifting component 7 are disposed inside the second sleeve 2. The ball-dropping component 61 passes through the second sleeve 2 and contacts the ball-collecting component 62. The lifting component 7 is connected to the ball-collecting component 62. The ball-collecting component 62 has a ball outlet 621 away from the ball-dropping component 61. The second sleeve 2 has a ball inlet 21 at the end away from the ground.

[0049] The lifting component 7 is connected to the ball collecting component 62. The lifting component 7 moves the ball collecting component 62 along the length of the first sleeve 1 to connect or close the ball inlet 21 and the ball outlet 621.

[0050] Specifically, such as Figures 1 to 8 As shown, the ball-dropping component 61 is sleeved at the lower end of the second sleeve 2. The ball-dropping component 61 is located between the second sleeve 2 and the first sleeve 1 to collect the filter balls filtered by the upper sieve plate component 3. Alternatively, when the second sieve plate 32 is flipped, the ball-dropping component 61 is adapted to collect impurity balls. The ball-dropping component 61 also passes through the second sleeve 2 and contacts the ball-collecting component 62. That is, the ball-dropping component 61 discharges the impurity balls or filter balls into the ball-collecting component 62, and the ball-collecting component 62 collects the impurity balls or filter balls. Alternatively, the ball-dropping component 61 also passes through the second sleeve 2, and one end of the ball-dropping component 61 passing through the second sleeve 2 is located above the ball-collecting component 62.

[0051] The lifting component 7 is located inside the second sleeve 2 and is connected to the ball collecting component 62. The lifting component 7 moves the ball collecting component 62 in the vertical direction to connect or close the ball inlet 21 and the ball outlet 621.

[0052] For example, the ball collecting component 62 is located at the lower end of the second sleeve 2. After the water filtration process is demonstrated, the impurity balls and filter balls are collected in the collecting component. The lifting component 7 is adapted to lift the ball collecting component 62 upwards. When the inlet 21 of the second sleeve 2 is connected to the outlet 621 of the ball collecting component 62, the impurity balls and filter balls pass through the outlet 621 and the inlet 21, thus simulating the water filtration process above the first screen plate 31 and the second screen plate 32. At this time, the lifting component 7 moves the ball collecting component 62 downwards, thereby moving the ball collecting component 62 to the lower end of the second sleeve 2.

[0053] The dynamic demonstration device for the water filtration principle of this invention, by setting a ball-dropping component 61 and a ball-collecting component 62, is suitable for collecting impurity balls and filter balls, and then collecting the impurity balls and filter balls onto the ball-collecting component 62. The lifting component 7 lifts the ball-collecting component 62 so that the ball inlet 21 and the ball outlet 621 are connected or closed, thereby facilitating the circulation of impurity balls and filter balls and improving the operational stability of the dynamic demonstration device for the water filtration principle.

[0054] In some embodiments, the dynamic demonstration device for the water filtration principle further includes a first stroke induction switch, which is connected to the end of the second sleeve 2 away from the ground.

[0055] Specifically, such as Figures 1 to 8 As shown, the first limit switch is connected to the upper end of the second sleeve 2. When the inlet 21 and outlet 621 are connected, the ball collecting component 62 contacts the first limit switch. At this time, the lifting component 7 stops lifting the ball collecting component 62 upwards. Furthermore, the dynamic demonstration device of the water filtration principle also includes a second limit switch, which is located at the lower end of the second sleeve 2. When the ball collecting component 62 descends to a position that facilitates the collection of impurity balls and filter balls, that is, when the ball collecting component 62 descends to the lowest point of the second sleeve 2, the ball collecting component 62 contacts the second limit switch. At this time, the lifting component 7 stops moving the ball collecting component 62 downwards.

[0056] The dynamic demonstration device for the water filtration principle in this embodiment of the invention can detect the position of the ball collecting component 62 in the vertical direction by setting a first stroke sensor switch and a second stroke sensor switch, or set the range of movement of the ball collecting component 62 in the vertical direction, thereby improving the stability and safety of the ball collecting component 62 in the vertical direction.

[0057] In some embodiments, the ball-dropping component 61 includes a ball-dropping tube 611 and an inclined plate 612. One end of the ball-dropping tube 611 is connected to the inclined plate 612, and the inclined plate 612 is sleeved on the second sleeve 2. The other end of the ball-dropping tube 611 passes through the second sleeve 2 and is connected to the ball-collecting component 62. The side of the inclined plate 612 away from the ground has a preset included angle A with the length direction of the first sleeve 1, and 4°≤A≤15°. The height of the inclined plate 612 gradually decreases along the direction close to the ball-dropping tube 611.

[0058] Specifically, such as Figures 1 to 8 As shown, the inclined plate 612 is sleeved on the second sleeve 2. The inclined plate 612 is suitable for collecting impurity balls and filter balls. The upper end of the ball drop pipe 611 is connected to the lowest end of the inclined plate 612, thus facilitating the entry of impurity balls and filter balls on the inclined plate 612 into the ball drop pipe 611. The outlet of the ball drop pipe 611 is located above the ball collecting component 62, so that the impurity balls and filter balls in the ball drop pipe 611 enter the ball collecting component 62 through the ball drop pipe 611.

[0059] Furthermore, the dynamic demonstration device for the water filtration principle also includes a buffer 8. The upper end of the buffer 8 is connected to the lower end of the ball collecting component 62. The buffer 8 can be a rubber buffer block. The buffer 8 buffers the movement of the ball collecting component 62 in the vertical direction, thereby improving the stability and safety of the ball collecting component 62.

[0060] The upper surface of the inclined plate 612 has a preset angle A with the vertical direction. A can be 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, or 15°. This facilitates the collection of impurity balls and filter balls, improving the efficiency of the ball-dropping component 61 in collecting impurity balls and filter balls.

[0061] The dynamic demonstration device for the water filtration principle in this embodiment of the invention, by setting up a ball drop tube 611 and an inclined plate 612, facilitates the collection of impurity balls and filter balls, thereby improving the operational stability of the dynamic demonstration device for the water filtration principle.

[0062] In some embodiments, the dynamic demonstration device for the water filtration principle further includes a ball-sweeping component 9, which includes a collar 93, a sliding motor 92, and a ball-sweeping rod 91. The collar 93 is sleeved on the second sleeve 2, and the sliding motor 92 is disposed on the collar 93. The sliding motor 92 slides in the circumferential direction of the collar 93. The sliding motor 92 is connected to the ball-sweeping rod 91, which extends in a direction away from the second sleeve 2.

[0063] Specifically, such as Figures 1 to 8 As shown, the collar 93 is sleeved on the second sleeve 2, and the sliding motor 92 is mounted on the collar 93. The sliding motor 92 moves on the collar 93 and is connected to the sweeping rod 91, which extends radially along the first screen plate 31. When an impurity ball gets stuck on the first screen plate 31, the sliding motor 92 is activated, moving on the collar 93, thereby causing the sweeping rod 91 to remove the impurity ball.

[0064] Furthermore, when the first screen plate 31 swings in the up and down direction, the upper end of the first screen plate 31 contacts the collar 93, thereby driving the ball sweeping component 9 to swing in the up and down direction. When it is necessary to clean the impurity balls, the end of the first screen plate 31 away from the second screen plate 32 tilts upward, thereby causing the end of the ball sweeping component 9 away from the second screen plate 32 to tilt upward, thus improving the cleaning efficiency of the ball sweeping component 9.

[0065] The dynamic demonstration device for the water filtration principle in this embodiment of the invention improves the stability and safety of the operation of the dynamic demonstration device by setting up a ball-sweeping component 9. When impurity balls are stuck on the first screen plate 31, the ball-sweeping component 9 is activated to clean the impurity balls, thereby improving the stability and safety of the operation of the dynamic demonstration device for the water filtration principle. By arranging the inclined plate 612 at an angle, the efficiency and stability of the ball-dropping component 61 are improved.

[0066] In some embodiments, the lifting component 7 includes a cylinder body 71 and a slider 72. The slider 72 is disposed on the cylinder body 71 and is connected to the ball collecting component 62. The height of the bottom surface of the ball collecting component 62 gradually decreases along the direction adjacent to the ball outlet 621.

[0067] Specifically, such as Figures 1 to 8 As shown, the cylinder body 71 extends in the vertical direction, and the slider 72 is disposed on the cylinder body 71. The slider 72 is connected to the ball collecting component 62. The slider 72 moves in the vertical direction to make the ball collecting component 62 move in the vertical direction, thereby connecting or closing the ball inlet 21 and the ball outlet 621. The height of the bottom surface of the ball collecting component 62 gradually decreases along the direction adjacent to the ball outlet 621, thereby facilitating the discharge of impurity balls and filter balls when the ball inlet 21 and the ball outlet 621 are connected, improving the smoothness and stability of the dynamic demonstration device of the water filtration principle.

[0068] In some embodiments, the dynamic demonstration device for the water filtration principle further includes an upper cover plate 10, which is connected to the second sleeve 2 and the end of the first sleeve away from the ground. The swing assembly 4 includes a second drive member 41, a cam member 42, a connecting rod 43, a lower guide sleeve 44, and an upper guide sleeve 45. The second drive member 41 is connected to the cam member 42, and the other end of the cam member 42 is pivotally connected to the connecting rod 43. One end of the connecting rod 43 is arranged inside the lower guide sleeve 44, and the other end of the connecting rod 43 is arranged inside the upper guide sleeve 45. The upper guide sleeve 45 is connected to the upper cover plate 10.

[0069] The connecting rod 43 is pivotally connected to a plurality of first screen plates 31, and the second driving member 41 rotates to move the connecting rod 43 along the length direction of the first sleeve 1.

[0070] Specifically, such as Figures 1 to 3 As shown, the swing assembly 4 can be understood to include a swing component and a connecting rod component. The swing component includes a second drive component 41 and a cam component 42, and the connecting rod component includes a connecting rod 43, a lower guide sleeve 44, and an upper guide sleeve 45.

[0071] The lower end of the second driving component 41 is connected to the ground, and the driving end of the second driving component 41 is pivotally connected to the lower end of the cam component 42. The upper end of the cam component 42 is pivotally connected to the connecting rod 43, and the other end of the connecting rod 43 is pivotally connected to the plurality of first screen plates 31 respectively.

[0072] The upper end of the upper guide sleeve 45 is connected to the lower end of the cover plate. The upper end of the connecting rod 43 is arranged inside the upper guide sleeve 45, and the lower end of the connecting rod 43 is arranged inside the lower guide sleeve 44. The lower guide sleeve 44 is connected to the ground. The upper guide sleeve 45 and the lower guide sleeve 44 cooperate to guide and limit the movement of the connecting rod 43 in the vertical direction.

[0073] Furthermore, the cam component 42 includes a turntable and a rocker arm. One end of the turntable is connected to the output end of the second drive member 41, and the rocker arm is pivotally connected to one end of the turntable. For example, the center position of the turntable is connected to the output end of the second drive member 41, and the position of the turntable away from the center is pivotally connected to the lower end of the rocker arm. The side of the turntable that is pivotally connected to the lower end of the rocker arm is away from the second drive member 41. The upper end of the rocker arm is pivotally connected to the connecting rod 43. Furthermore, a guide sleeve can also be provided. The guide sleeve is provided on the connecting rod 43, and the upper end of the rocker arm is pivotally connected to the guide sleeve, thereby facilitating the second drive member 41 to drive the connecting rod 43 to reciprocate in the vertical direction.

[0074] Furthermore, the dynamic demonstration device for the water filtration principle can also be equipped with a drive bracket. The lower end of the drive bracket is connected to the ground, and the upper end of the drive bracket is connected to the second drive component 41 to fix the second drive component 41. The second drive component 41 can be a rocker arm motor, thereby improving the stability and safety of the dynamic demonstration device for the water filtration principle.

[0075] The dynamic demonstration device for the water filtration principle of this invention uses a swing component 4, a second driving component 41, and a connecting rod 43 to drive multiple first screen plates 31 to swing repeatedly in the up and down direction, thereby simulating the irregular movement during water filtration.
