[0016] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0017] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0019] Referring to the drawings of the specification, a slow-release filter element with a float ball, which can be placed vertically or tilted, includes a shell 10, a filter bottle 20 is also arranged in the shell, a float ball 30 that can be raised and lowered is arranged in the filter bottle, a first cavity 23 is formed in the filter bottle above the float ball, a block 40 made of slow-release filter material is arranged in the first cavity, the block will become smaller and lighter as it is diluted by water, a water inlet hole 21 is arranged on the filter bottle, and a slow-release hole 22 is also arranged above the filter bottle, the slow-release hole can flow the water in the shell into the filter bottle and connect with the block The slow-release hole can also make the water flow that has come into contact with the block flow out of the filter bottle; the float can float up as the slow-release of the block is consumed to reduce the volume of the first cavity to adapt to the slow-released block. After the water flows into the first cavity from the slow-release hole, it comes into contact with the block to dilute the slow-release filter material, and then can flow out of the filter bottle from the slow-release hole, and finally flow out from the water outlet of the outer shell with the water flow. As the mass of the block becomes smaller, the float can gradually move up in the filter bottle, so that the first cavity becomes randomly smaller as the degree of slow release in the block is randomly released, so that there will not be a lot of water entering the first cavity from the slow-release hole, thereby reducing the speed at which the block is slowly released.

[0020] During use, a water inlet 11 is arranged at the lower end of the shell, a water outlet 12 is arranged at the upper end of the shell, a water passage 13 is arranged between the inner periphery of the shell and the outer periphery of the filter bottle, the water flow of the water inlet can flow to the water outlet through the water passage, the water inlet hole is located at the bottom of the filter bottle and can be connected with the water flow flowing into the water inlet, and the slow-release hole is located at the top of the filter bottle and can be connected with the water flow in the water passage.

[0021] Preferably, the outer circumference of the float can be adapted to the inner circumference of the filter bottle, and the float can divide the inside of the filter bottle into a first cavity and a second cavity 24 distributed up and down. In use, the first cavity and the second cavity may not be connected, and the water flow in the second cavity cannot flow into the first cavity, ensuring that only the water flow flowing in from the slow release hole can perform the slow release operation. The first cavity can be connected to the slow release hole, and the second cavity can be connected to the water inlet hole.

[0022] Further, the filter bottle includes a lower shell 25 and an end cap 26, the end cap is arranged at the upper opening of the lower shell, the slow-release hole is arranged on the end cap, and the water inlet is arranged in the middle of the bottom of the lower shell. A hollow portion is arranged in the middle of the lower shell, and the hollow portion can be formed by a first cavity and / or a second cavity, and the cross-sections of the upper and lower ends of the hollow portion can be consistent. A floating ball is arranged in the hollow portion, and the outer periphery of the floating ball can be adapted to the inner periphery of the hollow portion.

[0023] Specifically, the utility model is as follows: a float is placed at the bottom of a filter bottle filled with filter material, a block made of slow-release filter material is placed on the upper end of the float, a slow-release hole is opened on the top of the filter bottle, raw water enters the filter bottle from the upper slow-release hole and contacts and dissolves with the block, and then precipitates from the slow-release hole and combines with the raw water to achieve the effect of removing residual chlorine. During the consumption process, the mass of the block gradually decreases, and the float lifts the filter bottle, thereby solving the problem of insufficient sinking and precipitation of the filter material block and poor residual chlorine removal effect.

[0024] The above description shows and describes the preferred embodiments of the utility model. As mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
