[0037] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figure 1 As shown, an automatic drug dispensing device includes a tank 1 for containing water, a tablet collection box 2 with a mesh structure located inside the tank 1, the tablet collection box 2 being connected to a buoyancy body 3 so that the tablet collection box 2 is suspended when immersed in water; and a closable drug dispensing port 101 located on the upper side of the tank 1.

[0040] A dispensing port 101 is provided at the upper part of the tank body 1, through which tablets 7 can be dispensed into the tank body 1. The dispensing port 101 may have a cover to seal the tank body 1 after dispensing to prevent chlorine gas leakage. In some embodiments, the cover may be provided at the dispensing port 101 by providing an openable and closable insert plate 104. The insert plate 104 may be slidably connected to the tank body 1, for example. When dispensing is required, the dispensing port 101 is opened by pulling the insert plate 104, and after dispensing is completed, the dispensing port 101 is closed by pushing the insert plate 104. The cover of the dispensing port 101 of the present invention may also be connected to the dispensing port 101 in other ways, such as by rotation, to achieve an openable / closable connection.

[0041] The tablet collection box 2 is located inside the tank body 1. The tablets 7 put into the above-mentioned dispensing port 101 will fall into the tablet collection box 2. The tablet collection box 2 has a mesh structure, which facilitates water to flow into the inside of the tablet collection box 2 to contact the tablets 7 and dissolve them.

[0042] The tank body 1 may, for example, have a circular horizontal cross-section, with an internal cavity formed inside for containing water. Preferably, a conical bottom is formed at the lower part of the tank body 1, meaning the cross-sectional area gradually decreases from top to bottom, which facilitates the accumulation of impurities at the bottom of the tank body 1. Furthermore, a waste discharge port 102 can be provided at the lower end of the tank body 1. The conical bottom can be used to collect the impurities, and a valve can be installed on the waste discharge port 102, allowing the waste to be discharged by opening the valve.

[0043] The top of the tank 1 is provided with a detachable observation cover 103. The observation cover 103 can be made of transparent material such as glass. The condition inside the tank 1 can be checked through the observation cover 103, and the observation cover 103 can be removed when necessary to repair and replace the components inside the tank 1.

[0044] The outer contour of the pill collection box 2 is slightly smaller than the inner cavity of the container 1, thereby preventing the pills 7 from falling outside the pill collection box 2. Preferably, the buoyancy body 3 is located on the upper side of the pill collection box 2, so that the pill collection box 2 can be completely immersed in water.

[0045] In some embodiments, a base 8 for supporting the tank 1 may be provided on the lower side of the tank 1. Preferably, the tank 1 and the base 8 have a separable structure to facilitate installation, cleaning of the interior of the tank 1, and equipment maintenance.

[0046] In some embodiments, such as Figure 1 and Figure 3 As shown, the automatic dosing device also includes an automatic water replenishment system 4, which is connected to the tank 1. This system replenishes water to the tank 1 when the water level is below the low water level 92 and stops replenishing water when the water level reaches the high water level 91. Preferably, the automatic water replenishment system 4 includes a float valve 401 located inside the tank 1 and connected to the water outlet of the automatic water replenishment system 4, enabling automatic control of water replenishment. The tablet collection box 2 of this invention is connected to the buoyancy body 3 and can rise and fall with the water level in the tank 1, avoiding obstruction to the operation of the float valve 401. The buoyancy body 3 preferably has an annular structure, providing greater buoyancy, and the annular holes facilitate the falling of tablets into the tablet collection box 2.

[0047] like Figure 1 As shown, the automatic dosing device also includes a water output system 6, which includes a delivery pump 601. The suction end of the delivery pump 601 is connected to the tank 1, and the output end of the delivery pump 601 can be connected to a swimming pool through a pipe to deliver the solution into the swimming pool.

[0048] In real-world applications, many swimming pool water treatment equipment rooms, including equipment and stairs, become corroded after a period of use. Through continuous exploration, the inventors of this application discovered that the root cause of this phenomenon is that the chemicals in the dosing tank continuously release chlorine gas.

[0049] To address the above problems, in some embodiments, such as Figure 1 As shown, the tank 1 has a sealable inner cavity, which can reduce the diffusion of chlorine gas into the outside air and reduce the corrosive effect on the environment.

[0050] However, the inventors of this application have discovered that even if the tank 1 is designed to be airtight, it can only temporarily seal the chlorine gas in the inner cavity of the tank 1. However, when the dosing or other operations are performed, the dosing port 101 needs to be opened. At this time, the chlorine gas sealed in the inner cavity of the tank 1 will diffuse into the air, which still poses a problem of environmental corrosion.

[0051] To further solve the above-mentioned technical problems, the inventors of this application have creatively designed a chlorine adsorption unit 5. The inlet 51 of the chlorine adsorption unit 5 is connected to the upper end of the tank 1, and the outlet 531 of the chlorine adsorption unit 5 is connected to the atmosphere. The chlorine gas volatilized from the solution will be filtered out by the chlorine adsorption unit 5, thereby solving the corrosive adverse effects of chlorine on the swimming venue environment.

[0052] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the chlorine adsorption unit 5 includes a cylindrical body 53 and a filter layer 54 located inside the cylindrical body 53. The filter layer 54 includes a first porous material layer 541, an activated carbon layer 542, an activated adsorption material layer 543, and a second porous material layer 544 sequentially arranged from the inlet 51 to the outlet 531 of the chlorine adsorption unit 5. Through the above-mentioned multi-layer filtration and adsorption, chlorine can be effectively removed, effectively reducing the corrosive effect of chlorine on the swimming pool environment. The activated adsorption material layer 543 can be, for example, activated alumina.

[0053] Figure 4 The chlorine filtration process is further indicated in the text, such as... Figure 4 As shown, chlorine gas evaporates from the solution inside tank 1. Since other parts of tank 1 are designed to be sealed, the chlorine gas can only be discharged through the chlorine adsorption unit 5. When flowing through the chlorine adsorption unit 5, it passes through the first porous material layer 541, the activated carbon layer 542, the activated adsorption material layer 543, and the second porous material layer 544 in sequence. After the above filtration process, the chlorine gas in the discharged gas is effectively removed, and finally discharged into the pool environment through the outlet 531.

[0054] like Figure 2 As shown, the automatic dosing device further includes an upper cover 52 that is detachably connected to the cylinder 53. The filter layer 54 inside the cylinder 53 can be replaced by opening the upper cover 52, which improves the convenience of maintenance.

[0055] Example 2

[0056] This embodiment is a further improvement on embodiment 1. In this embodiment, a closed automatic drug delivery unit 10 is added.

[0057] Specifically, in Example 1, when the tablets are added into the tank 1 through the dosing port 101, the cover of the dosing port 101 must be opened. At this time, the chlorine gas sealed inside the tank 1 will diffuse outward and affect the swimming pool environment.

[0058] To address the aforementioned issues, this embodiment adds an automatic dosing unit 10. This unit 10 includes a water flow sensor 1001, a controller 1002, a medicine container 1003, and a screw conveyor 1004. The medicine container 1003 holds the medicine tablets. The inlet of the screw conveyor 1004 is connected to the medicine container 1003, and the outlet of the screw conveyor 1004 is connected to the tank 1, for conveying the medicine tablets into the tank 1. In this embodiment, since the medicine container 1003 and the screw conveyor 1004 are not connected to the outside environment, chlorine leakage during dosing is avoided.

[0059] The water flow sensor 1001 is used to detect the water flow signal in the inlet pipe of the automatic water replenishment system 4. When there is water flow in the inlet pipe 402, that is, when the automatic water replenishment system 4 replenishes water into the tank 1, the water flow sensor 1001 sends a signal to the controller 1002. After receiving the water flow signal, the controller 1002 further controls the screw conveyor 1004 to work, adding tablets into the tank 1, and stopping the addition of tablets when the amount of tablets added reaches the preset amount.

[0060] In this embodiment, the automatic dosing device determines whether it is in a water replenishment state based on the water flow signal from the inlet pipe 402, and then controls the screw conveyor 1004 to add chemicals into the tank 1. Throughout the entire process, the space inside the tank 1 remains sealed, thus completely solving the problem of chlorine leakage.

[0061] Example 3

[0062] In the structure of Example 2, moisture in the solution can easily enter the screw conveyor 1004 and the medicine container 1003, causing the stored tablets 7 to become damp. To avoid the tablets 7 becoming damp, this example further improves upon Example 2. Specifically, in this example, the outlet of the screw conveyor 1004 extends downwards through the wall of the tank 1 towards the interior of the tank 1 to form a sliding channel 1005, and the end of the sliding channel 1005 extends downwards to form a medicine storage section 1006. The tablets discharged from the screw conveyor 1004 can slide along the sliding channel 1005 towards the medicine storage section 1006.

[0063] A sealing cover 1007 capable of closing the lower port of the medicine storage section 1006 is provided at the lower port, along with an elastic element 1009 that holds the sealing cover 1007 closed. Thus, in its natural state, the elastic element 1009 provides the elastic force to hold the sealing cover 1007 closed, preventing moisture from entering the screw conveyor 1004 and the medicine compartment 1003 and causing the tablets to become damp. The elastic element 1009 is preferably a helical spring. When the lower port is closed, the helical spring not only tightens the sealing cover 1007, but its helical structure also helps to retain the tablets in the medicine storage section 1006.

[0064] A pull cord 1008 is provided between the tablet collection box 2 and the sealing cover 1007. Before the tablet collection box 2 falls to its lowest position, the sealing cover 1007 can be pulled down by the pull cord 1008 to open the lower port, allowing the tablets in the storage section 1006 to fall. At this time, the automatic dispensing device is in a water replenishment state. The added water washes away the tablets, which helps the tablets dissolve quickly and evenly. Furthermore, with the lower port open, the increased pitch of the helical spring reduces its holding effect on the tablets, which helps the tablets fall evenly and gradually, rather than suddenly.

[0065] In some embodiments, the free end of the valve stem 4011 of the float valve 401 is connected to the buoyancy body 3. The buoyancy body 3 is used instead of the float, which increases the magnitude of buoyancy and reduces the number of parts, thereby reducing manufacturing costs.

[0066] The above provides a detailed description of the automatic drug dispensing device according to the preferred embodiment of the present invention. However, those skilled in the art can make various modifications, alterations, and combinations based on this description, and all such modifications, alterations, and combinations fall within the protection scope of the claims of this application.
