Description

Technical Field

[0001] This utility model relates to a pool filter bottle, specifically a pool filter bottle. Background Technology

[0002] In the field of liquid filtration, filter bottles, as the core filtration carrier, are widely used in many industries such as water treatment, chemical production, and food processing. Their main function is to intercept impurities, particulate matter, and other pollutants in the liquid through the filter element loaded inside, so as to achieve the purpose of liquid purification.

[0003] Existing filter bottles typically employ a design with a connecting groove at the top for connection to the supply line. This groove's dimensions are matched to the connector at the end of the supply line. To ensure a proper seal, a sealing ring is installed on the inner wall of the groove. During assembly, the operator inserts the supply line connector into the groove. Since the sealing ring only adheres to the groove's inner wall due to its elasticity, the outer wall of the connector directly frictionates with the sealing ring during supply line installation (insertion or removal). This friction causes the sealing ring to move outwards. As the sealing ring's elasticity diminishes and its fit with the groove's inner wall decreases over time, this movement becomes more pronounced, eventually leading to the sealing ring detaching from the groove. Therefore, a new pool filter bottle is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a swimming pool filter bottle to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pool filter bottle, comprising a bottle body, a bottle cap mounted on the bottle body, and a filter element disposed within the bottle body. The bottle cap is provided with an inlet channel and an outlet channel. The feature is that it further includes a connecting ring disposed on the top of the filter element, a connecting nozzle mounted on the connecting ring for connecting the connecting ring and the outlet channel on the bottle cap, a sealing ring mounting groove disposed on the connecting ring for mounting a sealing ring, and a sealing ring mounted on the sealing ring mounting groove.

[0006] A further preferred embodiment includes a partition, a connecting pipe disposed on the partition and connected to the liquid outlet channel, and a docking sleeve disposed at the lower part of the partition for fitting onto the docking ring.

[0007] A further preferred embodiment includes a plug located at the top of the bottle cap; the liquid outlet channel includes a horizontal channel that runs through the bottle cap and a vertical channel connected to the bottom of the horizontal channel for insertion and connection of a connecting tube; the liquid inlet channel includes several sub-channels located at the top of the plug.

[0008] Further preferably, it also includes several water inlets disposed on the outside of the partition and a coarse filter screen disposed at the water inlets to perform preliminary filtration of the liquid.

[0009] In a further preferred embodiment, the inlet is provided with a slot for inserting a coarse filter screen, and the partition is also provided with a notch that connects to the slot. Upper limit blocks are formed on both sides of the slot through the notch, and an upper limit plate is formed in the middle of the slot.

[0010] A further preferred embodiment includes a protrusion on the coarse filter screen that facilitates the removal of the coarse filter screen.

[0011] The beneficial effects of this utility model are as follows: by setting a sealing ring mounting groove on the mating ring, the sealing ring is installed on the sealing ring mounting groove of the mating ring, and the mating ring forms an internal support force on the sealing ring, which greatly improves the installation firmness of the sealing ring and prevents it from easily falling off. By setting several water inlets on the partition and installing coarse filter screens at the water inlets, the liquid can be initially filtered through the coarse filter screens, removing large particulate impurities and thus reducing the clogging rate of the filter element. By detachably installing the coarse filter screen on the water inlet and setting up several water inlets separately, the coarse filter screen is treated as an individual unit. When it is damaged or needs to be replaced, only the coarse filter screen that needs to be replaced needs to be replaced, without having to replace all the coarse filter screens, resulting in low usage and maintenance costs.
