Description

Technical Field

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

[0002] A pool dosing system is a device used to add chemicals to a pool's circulating water system. Its core principle is to dissolve solid chemicals in water and deliver them evenly to the pool. The main body of the dosing system is a dissolving tank with a screw cap at the bottom for manually loading solid tablets (such as disinfectant tablets). As the circulating water flows through the dissolving tank, the tablets are slowly dissolved and diluted. The resulting solution is then carried by the water flow into the pool's distribution pipes, achieving even dosing. It is typically installed on the distribution lines of the circulating water system to ensure uniform distribution of the solution and prevent excessively high local concentrations.

[0003] In practical use, valves are usually installed on the pipelines before and after the pool tubular chemical dosing device for easy maintenance. This allows for convenient closure of the device for repairs and operation. However, current tubular chemical dosing devices do not integrate valves, requiring additional installation on the pipeline, which presents installation inconvenience. Furthermore, the base of the tubular chemical dosing device is fixed and cannot be adjusted, leading to instability due to the gap between the bottom of the device and the ground after installation on the pipeline. Utility Model Content

[0004] The purpose of this invention is to provide a tubular dosing device for swimming pools, which solves the aforementioned problems of existing tubular dosing devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tubular dosing device for swimming pools includes a dissolving tank, a lid, and a base assembly. The dissolving tank has an internal chamber for holding solid disinfectant tablets. The lid is located at the top of the tank for sealing and adding the disinfectant. The base assembly is located at the bottom of the tank. An inlet is located on the bottom surface of the tank, and an outlet is located on the lower part of the outer wall. Both the inlet and outlet communicate with the dissolving chamber. An inlet valve for adjusting the inlet flow rate is installed on the inlet, and an outlet valve for controlling the flow of the disinfectant is installed on the outlet. The base assembly includes a support base and an adjusting component. The support base is connected to the bottom of the tank, and the adjusting component is connected to the support base, allowing adjustment of the vertical distance between the bottom of the tank and the mounting surface (e.g., the ground).

[0006] Furthermore, the support base is designed as a frustum-shaped structure with an upper diameter smaller than the lower diameter, and it is hollow. The upper end of the support base is threaded to the lower end of the dissolving tank. The water inlet valve is housed in the internal cavity of the support base. A clearance groove for operating the water inlet valve handle is provided on the side wall of the support base.

[0007] Furthermore, multiple clearance grooves are provided and evenly distributed along the circumference of the support sidewall, facilitating valve operation from different angles.

[0008] Furthermore, the support base adjustment component includes a height adjustment block. The height adjustment block has an internally threaded hole (threaded groove) at its center. An externally threaded post (stud) extends downwards from the lower end of the support base, and this stud engages with the internally threaded hole of the height adjustment block. By rotating the height adjustment block, the distance between it and the lower end face of the support base can be changed, thereby achieving fine-tuning of the overall height.

[0009] Furthermore, the lower end of the height adjustment block is provided with a mounting flange, which has multiple mounting holes for fixing the entire dosing device to the ground or base using fasteners such as bolts.

[0010] Furthermore, a transparent observation window is provided on the outer wall of the dissolving tank along its vertical direction, which is used to visually observe the remaining amount of tablets in the dissolving chamber.

[0011] The beneficial effects of this utility model are: This invention integrates the inlet and outlet valves directly onto the dosing device body, eliminating the need for additional valve installation on external pipelines, simplifying the system structure, and reducing installation costs and complexity. The threaded support adjustment mechanism allows for flexible adjustment of the dosing device's installation height, ensuring tight contact between the bottom of the device and the support surface, eliminating issues of suspension or wobbling caused by size mismatches, and resulting in a more stable installation.

[0012] The circumferentially distributed clearance grooves facilitate the operation of the inlet valve; the transparent observation window makes the dosage check clear at a glance without opening the tank lid; the integrated valve makes equipment isolation and maintenance more direct; the frustum-shaped support provides stable support and also provides installation and protection space for internal valves. The overall structure is compact and the functions are complete. Attached Figure Description

[0016] like Figure 1 As shown, the main body of the pool tubular dosing device is a cylindrical dissolving tank 1, typically made of corrosion-resistant plastic (such as UPVC). The interior of the dissolving tank 1 contains a dissolving chamber 11 for holding solid disinfectant tablets. An openable lid 2 is attached to the top of the dissolving tank 1 via threads or snap-fit ​​for easy addition of disinfectant. A long, transparent observation window 16, made of acrylic or glass, is embedded in the upper side wall of the dissolving tank 1 for observing the tablet dissolution process.

[0017] The dissolving tank 1 has an inlet 12 at the center of its bottom and an outlet 13 on the lower side wall. An inlet valve 14 is installed at the inlet 12; in this example, a ball valve or butterfly valve can be used, to precisely control the water flow into the dissolving chamber, thereby adjusting the dissolution rate of the agent. An outlet valve 15 is installed at the outlet 13; similarly, a ball valve can be used, to disconnect the dosing device from the downstream pipeline when maintenance or replacement of the dosing device is required.
