DETAILED DESCRIPTION
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.
[0025] like Figure 1As shown, this embodiment discloses a pure water circulation device, including a second pipe body 2, a third pipe body 3, and a pipeline 4. The second pipe body 2, the third pipe body 3, and the pipeline 4 are connected end to end to form a circulating water path inside. Specifically, the second pipe body 2 includes an extension pipe 1 21 at the upper end, which is arranged in a horizontal direction. The third pipe body 3 includes an extension pipe 2 31 at the upper end. The extension pipe 2 31 is installed at the lower end of the extension pipe 1 21, which is arranged in a vertical direction. The top of the extension pipe 2 31 is connected to the extension pipe 1 21. The height of the third pipe body 3 and the pipeline 4 are both lower than that of the extension pipe 1 21. The pipeline 4 includes a pipeline 1 41, a pipeline 2 42, and a pipeline 3 43. The third pipe body 3 is interconnected with the pipeline 1 41, the pipeline 2 42, and the pipeline 3 43. The heat dissipation pipeline of the component 5 to be dissipated is also connected between the pipeline 2 42 and the pipeline 3 43. The cooling water is transported through the heat dissipation pipeline of the component 5 to be dissipated to perform heat exchange with the heat dissipation component 5.
[0026] like Figure 1 、 Figure 3 As shown, a fixed plate 32 and a slide plate 33 are mounted on the inner wall of the second extension tube 31. The slide plate 33 is located below the fixed plate 32 and can move up and down along the axial direction of the second extension tube 31. A third boss 311 is provided on the inner wall of the second extension tube 31, the upper end surface of which abuts against the lower end surface of the fixed plate 32. The fixed plate 32 also has a first through-hole 321, which axially extends through the fixed plate 32. Four through-holes 321 are evenly distributed along the circumference of the fixed plate 32.
[0027] like Figure 3 As shown, the slide 33 is provided with a second through-hole 331, which extends axially through the slide 33. The slide 33 is also provided with a first groove 332, which is recessed downward along the upper end surface of the slide 33. The first grooves 332 are evenly distributed along the circumference of the slide 33 and correspond one to the first through-hole 321. The first grooves 332 are mounted with sealing balls 34, which snap into the first grooves 332 and are located below the first through-hole 321. The center of the sealing ball 34 is flush with the upper end surface of the slide 33. The slide 33 is also provided with a third through-hole 333, which is located below the first groove 332 and extends downward through the slide 33 along the bottom surface of the first groove 332.
[0028] A fourth boss 312 is formed on the inner wall of the second extension tube 31 . When the slide plate 33 is located at the lower limit position, the bottom of the slide plate 33 abuts against the top of the fourth boss 312 .
[0029] like Figure 1 、 Figure 3As shown, it also includes a cylinder 2 8, a connecting rod 81 is installed at the output end of the cylinder 2 8, and a connecting ring 82 is installed on the connecting rod 81. The extension tube 2 31 passes through the connecting ring 82, and the connecting ring 82 is located radially outside the slide 33. The slide 33 is made of iron material, and the connecting ring 82 is a magnet. When the connecting ring 82 moves up and down, it drives the slide 33 to move up and down, thereby driving the sealing ball 34 to move synchronously. The sealing ball 34 moves upward so that the sealing ball 34 blocks the bottom of the through hole 1 321 to seal it.
[0030] like Figure 3 、 Figure 4 As shown, it also includes a limiting cylinder 9, a connecting ring 82 is inserted into the limiting cylinder 9, and the connecting ring 82 can move up and down along the inner wall of the limiting cylinder 9. The limiting cylinder 9 is provided with a second groove body 91, and the connecting rod 81 passes through the second groove body 91, and the connecting rod 81 can move up and down along the inner wall of the second groove body 91.
[0031] like Figure 1 、 Figure 2 As shown, the upper end of extension tube 1 21 is mounted with tube assembly 1, and the bottom of tube assembly 1 is connected to extension tube 1 21. Specifically, tube assembly 1 includes tube 11, the inner wall of which is slidably connected to slider 12. Slider 12 divides the inner wall of tube assembly 1 into upper and lower inner cavities 14 and 15, respectively. Inner cavities 15 are connected to extension tube 1 21. The outer wall of slider 12 is clearance-matched with the inner wall of tube 6, so that the gap between inner cavities 14 and 15 reduces the amount of blowby.
[0032] The device also includes a tube 6, which contains a sealed cavity. A piston 63 is mounted on the inner wall of the tube 6. Driven by cylinder 1 7, piston 63 can move axially along the tube 6. Piston 63 divides the cavity within the tube 6 into cavity 1 61 and cavity 2 62. Cavity 2 62 communicates with inner cavity 1 14. When piston 63 moves to the left, the pressure in cavity 2 62 and inner cavity 1 14 decreases, creating a pressure differential between the upper and lower ends of slider 12, causing it to move upward. Slider 12 is provided with a groove 122 to reduce weight.
[0033] like Figure 2 As shown, the tube assembly 1 also includes a sleeve 13 at the bottom. The bottom of the tube body 11 is inserted into the upper end of the sleeve 13, and the bottom of the sleeve 13 is connected to the extension tube 1 21. The sleeve 13 is provided with a boss 131. When the slider 12 is at the lower limit position, the upper end of the boss 131 abuts the lower end of the slider 12.
[0034] like Figure 2As shown, one side of the slider 12 is provided with an air channel 121. One end of air channel 121 extends through the upper end surface of the slider 12 and communicates with the inner cavity 14. The other end of air channel 121 extends through the side wall of the slider 12. The sleeve 13 is provided with an annular groove 132 and an air channel 133. Annular groove 132 is recessed radially outward along the inner wall of the sleeve 13 to form an annular groove. When the slider 12 is in the lower limit position, the end of air channel 121, away from the inner cavity 14, communicates with annular groove 132. Annular groove 132 communicates with air channel 2 133. Air channel 2 133 includes air channel 3 1331, which communicates with the inner cavity 2 15 located below the boss 131.
[0035] Because the outer wall of slider 12 and the inner wall of tube 6 have a clearance fit, air will flow from the higher pressure chamber 14 or chamber 2 15 to the lower pressure chamber 15. When the pressure in chamber 14 is higher and the pressure in chamber 2 15 is lower, when piston 63 moves leftward, chamber 14 reaches a lower pressure, increasing the response time for slider 12 to rise and activate. This reduces slider 12 sensitivity and reduces the distance it can rise, resulting in a lower minimum pressure in chamber 2 15. Therefore, when slider 12 is at its lower limit, chambers 14 and 15 are interconnected through airway 121, annular groove 132, and airway 2 133, ensuring that the pressures in chambers 14 and 15 approach equilibrium.
[0036] The circulation method of the above-mentioned pure water circulation device is:
[0037] ① Such as Figure 3 As shown, in the non-operating state, the liquid level of the pure water circulation device is indicated by the dashed line L in the figure. Liquid level L is lower than the slide 33, creating a gas space in the pipeline above the liquid level L. The upward movement of the connecting ring 82 drives the slide 33 upward, thereby driving the sealing ball 34 to abut the bottom of the first through-hole 321. The fixed plate 32 seals the second extension tube 31, and the cavity above the fixed plate 32 communicates with the first extension tube 21 and the second inner cavity 15.
[0038] Driven by cylinder 1 7 , piston 63 moves to the left, the air pressure in inner chamber 14 decreases, a pressure difference is formed on the upper and lower sides of slider 12 , and slider 12 moves upward, thereby reducing the air pressure in extension tube 1 21 and inner chamber 2 15 and making it greater than the air pressure in extension tube 2 31 below fixed plate 32 , and the cooling water in tube body 2 2 is sucked upward into extension tube 1 21 and extension tube 2 31 .
[0039] When the piston 93 moves to the left, due to the rapid change in the air pressure in the inner chamber 14, the inner chamber 14 and the inner chamber 2 15 cannot achieve air pressure balance in a very short time, so that the upper and lower sides of the slider 12 quickly produce a pressure difference and move upward. When the slider 12 moves upward, the air channel 121 is immediately disconnected from the annular groove 132, and the inner chamber 14 and the inner chamber 2 15 are no longer connected.
[0040] ② The piston 63 moves to the right under the drive of the cylinder 7, the air pressure in the inner cavity 14 increases, and the slider 12 falls back downward. At the same time, the connecting ring 82 moves downward to drive the slide plate 33 to move downward, thereby driving the sealing ball 34 to separate from the bottom of the through hole 321, and the cooling water above the fixed plate 32 flows downward, and the liquid levels of the tube body 2 2 and the extension tube 2 31 return to the same horizontal plane. The water circulation is completed by continuously sending the cooling water at the upper end of the tube body 2 2 into the extension tube 2 31. Due to the intermittent delivery of the cooling water during circulation, the cooling water inside the pipeline forms turbulence. When the cooling water exchanges heat with the heat dissipation pipe in the heat dissipation component 5, the cooling water close to the contact point heats up quickly. The cooling water close to the contact point is promptly merged with the cooling water far from the contact point through the turbulent flow, thereby improving the heat exchange effect.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
