DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the automatic water replenishing device for a pool in an embodiment of the present invention includes a water replenishing tank 1, a sealing tube 2, a water inlet pipe 3, a floating plate 4, a sealing plate 5 and a connecting piece 6. The water replenishing tank 1 has a water storage chamber 11. The bottom of the water replenishing tank 1 is provided with a water inlet hole 12 connected to the water storage chamber 11. The water replenishing tank 1 is provided with a connecting pipe 13 connected to the water storage chamber 11 and used to communicate with the pool. The sealing tube 2 is arranged corresponding to the water inlet hole 12 and is connected to the water storage chamber 11. The other end of the sealing tube 2 is blocked. The sealing tube 2 has an active cavity. The water inlet pipe 3 is connected to the sealing tube 2 and is used to transport water to the water storage chamber 11 through the sealing tube 2. The floating plate 4 is arranged in the water storage chamber 11 and is used to Floating on the water surface, the sealing plate 5 is adjustable in position and is arranged in the movable cavity. The density of the sealing plate 5 is greater than the density of the water body. The two ends of the connecting piece 6 are respectively connected to the floating plate 4 and the sealing plate 5. The floating plate 4 is used to drive the sealing plate 5 to move upward when the water level in the water storage cavity 11 rises. A first protrusion 41 is provided on the side of the floating plate 4 close to the water inlet hole 12. The first protrusion 41 is used to drive the sealing plate 5 to move downward when the water level in the water storage cavity 11 drops. The sealing plate 5 has a first position and a second position. In the first position, the sealing plate 5 blocks the water inlet hole 12. In the second position, there is a set distance between the sealing plate 5 and the water inlet hole 12.

[0028] When the automatic water replenishing device for the pool of the embodiment of the present invention is in use, the water replenishing tank 1 forms a communicating vessel with the pool through the connecting pipe 13. When the water level of the pool is within the height range of the water storage chamber 11, the water level of the water replenishing tank 1 can rise or fall with the change of the height of the pool to always keep the liquid level the same. When the liquid level in the pool drops, the water level in the water replenishing tank 1 drops, and at the same time, the float plate 4 moves with the liquid surface in the direction close to the sealing tube 2. When the first protrusion 41 abuts against the sealing plate 5, the float plate 4 continues to drop with the water level. The thrust applied to the sealing plate 5 away from the water replenishing tank 1 by the combination of the gravity of the float plate 4 itself and the pressure of the sealing plate 5 itself being greater than the pressure of the water body pressure in the active chamber on the sealing plate 5, the sealing plate 5 contacts the water inlet 12, thereby blocking the sealing plate 5. The water in the water inlet pipe 3 can enter the water storage chamber 11 through the movable chamber, and the sealing plate 5 continues to move downward and sinks to the bottom of the movable chamber to reach the second position, thereby realizing the water replenishment operation in the water replenishment tank 1, and meeting the requirement of replenishing water in the pool. When the water level in the water storage chamber 11 rises, the float plate 4 moves with the liquid surface in the direction away from the sealing tube 2. When the float plate 4 rises to the set height, that is, it pulls the sealing plate 5 toward the water replenishment tank 1 through the connecting piece 6 until the sealing plate 5 blocks the water inlet hole 12. The sealing plate 5 reaches the first position, and the water in the water inlet pipe 3 simultaneously applies an upward thrust to the sealing plate 5 to ensure the sealing effect of the sealing plate 5 on the water inlet hole 12. At this time, the water levels in the water replenishment tank 1 and the pool reach the set height, and the automatic water replenishment operation is completed.

[0029] The automatic water replenishing device for the water pool in the embodiment of the present invention realizes automatic water replenishment of the water pool based on the principle of communicating vessels, and automatically stops the water replenishment operation after the set water level is reached. It has a simple structure, convenient operation, and more reliable water replenishment operation, which improves the safety of the summer evaporative cooler when used.

[0030] It should be noted that when the water replenishing device is installed, the water replenishing device can be fixed in the pool, or the water replenishing tank 1 and the pool can be separated, and the water level change height of the pool must be within the height range of the water storage chamber 11.

[0031] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, a second protrusion 51 is provided on one side of the sealing plate 5 close to the floating plate 4. The diameter or the circumscribed circle diameter of the second protrusion 51 is smaller than the diameter of the water inlet hole 12. In the first position, at least part of the second protrusion 51 is inserted into the water inlet hole 12. By limiting the size of the second protrusion 51, it can be ensured that the second protrusion 51 can be inserted into the water inlet hole 12, and part of the second protrusion 51 can be extended into the water replenishment cavity through the water inlet hole 12. At this time, when the first protrusion 41 pushes the sealing plate 5 to move downward, the first protrusion 51 41 can directly push the second protrusion 51, increase the downward moving distance of the sealing plate 5 in the active cavity, ensure that the sealing plate 5 moves to below the connection position of the water inlet pipe 3 and the sealing tube 2 in the active cavity, and avoid that during the water replenishment stage, when the connecting piece 6 does not apply traction to the sealing plate 5 during the rising process of the floating plate 4, the sealing plate 5 is at the connection position of the water inlet pipe 3 and the sealing tube 2 in the active cavity, and the sealing plate 5 moves upward under the action of the water pressure in the active cavity to block the water inlet hole 12 to terminate the water replenishment operation, thereby ensuring the normal progress of the water replenishment operation.

[0032] Optionally, the second protrusion 51 is cylindrical, the sealing plate 5 is a disc structure, the second protrusion 51 is coaxially arranged on the sealing plate 5, the sealing tube 2 and the water inlet hole 12 are coaxially arranged, the second protrusion 51 and the sealing plate 5 are coaxially arranged, and the diameter of the sealing tube 2 and the straight drop difference of the water inlet hole 12 are smaller than the straight drop difference between the sealing plate 5 and the second protrusion 51, so as to ensure that when the sealing plate 5 moves, the second protrusion 51 can extend into the water storage chamber 11.

[0033] In some embodiments, the first protrusion 41 and the second protrusion 51 are both magnets, and the magnetism of the side of the first protrusion 41 close to the second protrusion 51 is opposite to the magnetism of the side of the second protrusion 51 close to the first protrusion 41. Through the principle of opposite poles repelling each other between magnets, force transmission can be achieved when the first protrusion 41 and the second protrusion 51 are not in contact, thereby effectively ensuring the driving effect of the floating plate 4 on the sealing plate 5 when it moves downward in the water storage chamber 11, and increasing the pushing distance of the floating plate 4 on the sealing plate 5 when it descends while the sizes of the first protrusion 41 and the second protrusion 51 remain unchanged, thereby ensuring the normal progress of the water replenishment operation.

[0034] Optionally, the water inlet pipe 3, the sealing pipe 2 and the water replenishing tank 1 are all made of non-magnetic materials, such as plastic.

[0035] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the water replenishment tank 1 includes a box body 14 and a cover body 15 that are detachably connected. The box body 14 is provided with an exhaust pipe 16 that is connected to the water storage chamber 11. The distance between the exhaust pipe 16 and the cover body 15 is smaller than the distance between the side of the floating plate 4 away from the cover body 15 and the cover body 15 when the sealing plate 5 is in the first position. The box body 14 and the cover body 15 form a sealed structure with the water replenishment tank 1, which can prevent the components in the water storage chamber 11 from being interfered with by other objects and extend the service life. At the same time, the exhaust pipe 16 is arranged. During the water replenishment and water level lowering stages, the water replenishment tank 1 can be connected with the atmospheric environment to ensure that the water level in the water storage tank and the water level in the pool change at the same time, and the air pressure in the water storage chamber 11 is prevented from changing and then the floating plate 4 in the water replenishment tank 1 rises and falls, so as to ensure the automatic water replenishment effect. By limiting the position of the exhaust pipe 16, the water in the water storage chamber 11 is prevented from flowing out through the exhaust pipe 16, so that the water replenishment operation can be automatically stopped, which is convenient for controlling the water level height of the pool.

[0036] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the connecting pipe 13 is connected to the bottom of the box body 14, and when the height of the water storage chamber 11 is constant, the maximum liquid level of the water storage chamber 11 and the water level of the pool are guaranteed to change synchronously.

[0037] In some embodiments, a sealing gasket is provided between the box body 14 and the cover body 15 to ensure the sealing of the connection position between the box body 14 and the cover body 15 .

[0038] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the connecting member 6 is a traction line, and a fixing member is provided on the side of the floating plate 4 facing away from the sealing plate 5. One end of the connecting member 6 passes through the floating plate 4 and is movably connected to the fixing member. The connecting member 6 is movably connected to the fixing member through the traction line. The length of the connecting member 6 between the floating plate 4 and the sealing plate 5 can be adjusted by winding part of the connecting member 6 around the fixing member and tying a slipknot on the fixing member. The highest position of the floating plate 4 in the water storage chamber 11 can be adjusted, thereby realizing the control of the water level in the pool. The operation is convenient and reliable.

[0039] Optionally, the fixing member is a fixing frame or a winding disk.

[0040] In some embodiments, the cross-section of the float plate 4 and the cross-section of the water storage chamber 11 are both circular, and the difference between the cross-sectional diameter of the water storage chamber 11 and the cross-sectional diameter of the float plate 4 is not greater than the dimension of the float plate 4 along the axial direction. By limiting the diameters of the water storage chamber 11 and the float plate 4, it is possible to prevent the float plate 4 from deflecting when moving relative to the water storage chamber 11 to affect the downward driving of the sealing plate 5 by the float plate 4, thereby ensuring that the first protrusion 41 can enter the active cavity through the water inlet hole 12 to push the sealing plate 5 to move, thereby ensuring the normal progress of the water replenishment operation.

[0041] Optionally, the first protrusion 41 is cylindrical, and a guide section is provided at the end of the first protrusion 41 , and the cross-sectional diameter of the guide section decreases in a direction away from the floating plate 4 .

[0042] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the diameter of the sealing tube 2 is larger than the diameter of the water inlet hole 12, the diameter of the sealing plate 5 is larger than the diameter of the water inlet hole 12 and smaller than the diameter of the sealing tube 2, and the length of the first protrusion 41 in the direction perpendicular to the floating plate 4 is not less than the sum of the distance from the water inlet pipe 3 to the water inlet hole 12 and the radius of the water inlet pipe 3. By taking into account the difference between the diameter of the sealing tube 2 and the diameter of the water inlet hole 12, the side wall of the water replenishment tank 1 is used to provide a stop for the sealing plate 5 at the end of the active cavity, which is convenient for installation. At the same time, the length of the first protrusion 41 is limited to ensure that the sealing plate 5 moves in the active cavity to below the connection position between the water inlet pipe 3 and the sealing tube 2, thereby ensuring that the water replenishment operation proceeds normally.

[0043] In some embodiments, Figure 1 and Figure 4 As shown, it includes a frame 7, and a water replenishment tank 1 is arranged on the frame 7. The frame 7 is used to lift the water replenishment tank 1 to a set height, and the height of the frame 7 is adjustable to adjust the height of the water replenishment tank 1. By setting the frame 7, it is convenient to fix the water replenishment tank 1. At the same time, the height of the water replenishment tank 1 can be adjusted by adjusting the height of the frame 7, thereby controlling the water replenishment line of the water pool to ensure that there is sufficient cooling water in the water pool.

[0044] In some embodiments, Figure 4 As shown, the frame 7 includes a frame 71, a support plate 72 and a support leg 73 arranged at the bottom of the frame 71. The support plate 72 is fixed to the frame 71 and fixedly connected to the water replenishment tank 1. The support plate 72 is provided with a through hole for the sealing tube 2 to pass through, and the length of the support leg 73 is adjustable.

[0045] Specifically, the support leg 73 includes a sleeve and an insertion rod. One end of the sleeve is fixedly connected to the frame 71, and the insertion rod is plugged into the sleeve. The sleeve is provided with first through holes at intervals, and the insertion rod is correspondingly provided with multiple second through holes. The first through holes and the second through holes are penetrated by fixing bolts. By increasing the insertion length of the insertion rod and the sleeve and fixing them with fixing bolts, the height of the frame 7 can be easily adjusted.
