Description

Water filter

This creation relates to a water filter device, especially one that allows the cleaning member to move linearly to clean the filter.

In order to filter the impurities contained in various fluids, most people use at least one filter to filter. Among them, in terms of water resources necessary for human life, heavy metals and toxic substances released from industrialized pollution, carcinogens (trihalomethanes) produced by disinfection of chlorides, and metal pipes that are transported, and various unknowns The source of infection outside the tube, therefore, users often install various water purifiers such as filter, filter or reverse osmosis at the outlet of tap water to filter impurities in the water.

After the water purifier is used for a period of time, the filter of the water purifier must be periodically cleaned, replaced, or reversed by a motor-driven water flow to keep the filtered water flowing smoothly and ensure the filtration quality.

However, for different water sources, the filtering effect of the same filter is not the same. Although it can set a fixed filter cleaning time as needed, in the busy society today, after removing the filter core by manpower, The way of cleaning is obviously not very convenient; in addition, before the time of cleaning the filter is scheduled, due to the gradual accumulation of a large amount of impurities during the continuous cleaning process The product will make the water in the space around the filter core become more and more turbid, and adhere to the outer surface of the filter core and the surrounding surface of the water purifier, and even settle down into sludge. In the general cleaning process, even if the surrounding surface of the filter is cleaned, it is impossible to effectively remove the impurities or sludge between the outer periphery of the filter and the surrounding of the water purifier, so that the filter will not only be cleaned. The frequency increases and the life of the filter is shortened. In view of this, in order to provide a structure different from the conventional technology and to improve the above-mentioned shortcomings, the creator has accumulated many years of experience and continuous research and development improvements, and this creation has not been produced.

Wherein, the straight tubular filter core has a clean water outlet end, and the clean water outlet end communicates with the inner space of the straight tubular filter core; the inner portion of the straight cylinder has a cylindrical space, and the straight cylinder has a first water outlet end and a water inlet end; a second water outlet end, the first water outlet end is connected to the water outlet end of the straight tube filter core, the straight tube filter core is coaxially positioned in the cylindrical space, and the second water outlet end has a control valve for controlling the straight tube outlet The water volume forms an annular space between the inner wall surface of the straight cylinder and the outer wall surface of the straight tubular filter; the collar is sleeved with a straight tubular filter core, and the inner ring mask of the collar has a first cleaning member for pressing the straight tube shape The outer wall of the filter; the periphery of the collar is screwed to at least one first screw, one end of any one of the first screws is coupled to a linking member, and at least one of the linking members is coupled to a driving member for driving at least A first screw is rotated in place such that the first cleaning member of the collar moves linearly to clean the outer wall of the straight tubular filter.

When implemented, the outer ring mask of the collar has a second cleaning member for pressing and cleaning the inner wall surface of the straight cylinder.

In one embodiment, one of the first screws is coupled to a first linking member, and at least one of the first linking members is coupled to a second linking member, and the second linking member is coupled to the driving member for driving at least one of the first screws to rotate in place.

In implementation, the first screw has a plurality of screws and is screwed to the periphery of the collar in a circular array. The first linkage is a first gear, and the second linkage is a second gear. The plurality of first gears are coupled to each other, and the driving member is a motor for driving a plurality of first screws to rotate synchronously and in the same direction.

When implemented, the inner side of the inner wall of the straight cylinder further has a first guiding portion, and one side of the collar further has a second guiding portion, and the second guiding portion is coupled to the first guiding portion in a relatively linear manner. .

In practice, the first guiding portion is a straight rod, and the second guiding portion is a hole that linearly penetrates one side of the collar, and the straight rod passes through the hole, so that the collar moves linearly with respect to the first guiding portion. .
