Description

Technical Field

[0001] This utility model relates to the field of swimming pool technology, specifically to a swimming pool dosing device. Background Technology

[0002] To maintain the cleanliness of swimming pool water, it is usually necessary to regularly add disinfectant tablets, typically chlorine tablets, to the pool. Currently, the most common method is to use a floating pool disinfectant dispenser. This dispenser consists of a shell containing floats and a storage chamber for the tablets. The storage chamber has inlet holes on its side wall, allowing pool water to enter. The tablets dissolve slowly in the water, effectively disinfecting the pool.

[0003] The current floating pesticide dispenser has the problem that it is difficult to quickly determine whether the pesticide has been dispensed. In order to replace it in time, it is necessary to open the shell from time to time for observation, which is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a swimming pool dosing device that solves the aforementioned problems of current swimming pool dosing devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A swimming pool dosing device includes a lower shell and an upper shell. The lower shell has a lower hemisphere and a cylindrical portion, with the cylindrical portion located at the lower end of the lower hemisphere. The lower shell is hollow to form a cavity for holding tablets. The cylindrical portion has water-permeable holes. The upper shell has an upper hemisphere and a counterweight, with the counterweight located at the upper end of the upper hemisphere. The upper and lower hemispheres are detachably connected. The cylindrical portion is configured such that when there are tablets in the cavity, it is located in the pool water. When the tablets in the cavity have completely dissolved, the weight of the counterweight drives the cylindrical portion to flip and be positioned above the pool water surface.

[0007] Furthermore, the counterweight part is conical in shape, with its outer diameter decreasing from bottom to top, and a counterweight block is provided in the counterweight part.

[0008] Furthermore, the counterweight is threadedly connected to the upper hemisphere.

[0009] Furthermore, the top of the lower hemisphere is provided with a insertion hole, and a tablet clip for clamping tablets is inserted into the insertion hole.

[0010] Furthermore, the tablet holder is provided with two clips spaced apart, and the two clips are used to clamp tablets stacked one on top of the other, with the lower part of the clips located in the cylindrical part.

[0011] Furthermore, the tablet holder is provided with a handle at the top.

[0012] Furthermore, the lower hemisphere has an upwardly extending flange at its top and an upper hemisphere has a mounting groove at its bottom, with the flange and the mounting groove connected by threads.

[0013] Furthermore, a flow regulating ring is provided on the outer wall of the cylindrical portion, and the flow regulating ring is rotatably disposed on the outer wall of the cylindrical portion.

[0014] The beneficial effects of this utility model are:

[0015] This utility model provides a swimming pool dosing device that effectively solves the problem of existing floating dosing devices making it difficult to quickly determine whether dosing is complete. The device includes a lower shell and an upper shell. The lower shell has permeable holes to allow pool water to enter the receiving cavity and dissolve the tablets. The upper shell has a counterweight; once the tablets have dissolved, the weight of the counterweight will automatically flip the device above the pool surface. This design eliminates the need for frequent opening of the shells for observation; users can determine whether dosing is complete simply by observing whether the device has flipped, greatly improving ease of use.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figures 1-3 As shown, this embodiment provides a swimming pool dosing device, including a lower housing 1 and an upper housing 2. The lower housing 1 has a lower hemisphere 11 and a cylindrical portion 12, with the cylindrical portion 12 located at the lower end of the lower hemisphere 11. The lower housing 1 is hollow to form a receiving cavity for holding tablets. The cylindrical portion 12 is provided with a water-permeable hole 13, allowing water from the swimming pool to enter the receiving cavity and dissolve the tablets.

[0026] Figure 2 and Figure 3 As shown, the upper housing 2 has an upper hemisphere 21 and a counterweight 22, with the counterweight 22 located at the upper end of the upper hemisphere 21. The counterweight 22 is conical in shape, with its outer diameter decreasing from bottom to top to increase the stability of the device. A counterweight block is provided in the counterweight 22 to increase the overall weight of the device. The counterweight 22 is connected to the upper hemisphere 21 by a thread, facilitating disassembly and replacement.

[0027] Figure 2 As shown, the lower hemisphere 11 has an insertion hole 14 at its top, into which a tablet holder 3 for holding tablets is inserted. Two clips 31 are spaced apart on the tablet holder 3, used to hold stacked tablets. The lower parts of the clips 31 are located within the cylindrical portion 12. A handle 32 is provided at the top of the tablet holder 3 for easy user operation.

[0028] The lower hemisphere 11 has an upwardly extending flange 15 at its top, and the upper hemisphere 21 has a mounting groove 23 at its bottom. The flange 15 and the mounting groove 23 are connected by threads to achieve a detachable connection between the upper housing 2 and the lower housing 1.

[0029] A flow regulating ring 4 is provided on the outer wall of the cylindrical part 12. The flow regulating ring 4 is rotatably provided on the outer wall of the cylindrical part 12 and is used to regulate the water flow rate entering the accommodating cavity, thereby controlling the dissolution rate of the tablet.

[0030] The working principle of this embodiment is as follows:

[0031] When the tablets are in the container, the entire device floats in the pool water due to buoyancy. As the tablets dissolve, the amount in the container gradually decreases, and the device's center of gravity gradually shifts upward. Once the tablets are completely dissolved, the weight of the counterweight 22 causes the cylindrical part 12 to flip, and the entire device flips above the pool surface. Users can determine whether the tablets have completely dissolved by observing whether the device has flipped, without needing to open the casing for observation, thus improving ease of use.

[0032] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
