Description

[0001] WATER FILTERING DEVICE [0002]

The present invention relates to a water filtering apparatus, and more particularly to a water filtering apparatus capable of replacing a filter element.

Currently, water filtering devices are commonly used in general homes and public places. 1, a conventional water filtering apparatus 1 includes a base 11 and a housing 13, a filter element 2 mounted on a base 11, and a housing 13 connected to a base 11, And the filter element 20 is received. A first pipe end 111 and a second pipe end 113 are correspondingly formed at a position where the filter element 2 is installed in the base 11 and the inlet 21 and the outlet 23 of the filter element 2 ) Is provided at the bottom thereof. The first pipe end 111 and the second pipe end 113 of the base 11 are mounted on the inlet 21 and the outlet 23 of the filter element 2 and are in fluid communication with each other.

Since the life of the filter element 2 is constant, the user has to replace the filter element 2 when the service life is reached. When the user wishes to replace the filter element 2 of the conventional water filtering apparatus 1, the housing 13 and the base 11 must first be separated and then the inlet 21 and outlet 22 of the filter element 2 23 must be separated from the first pipe end 111 and the second pipe end 113 of the bay 11 and then the filter element 2 must be taken out.

However, when the filter element 2 is used in general, water is left inside. Therefore, when the user takes out the filter element 2, the water remaining in the filter element 2 flows out from the filter element 2 to the lower inlet 21 and the outlet 23 so that the base 11 remains To the water. Generally, since various circuit components are provided on the base 11, there is a risk that the circuit components may be damaged if the base 11 comes into contact with the remaining water. Particularly, when one of the filter elements 2 is an ultraviolet (UV) filter element, a relatively high voltage must be connected to the UV filter element 2. If the base 11 comes into contact with the remaining water, The circuit components of the UV filter element 2 connected to the electrodes 11 are more easily damaged due to the high voltage and this damage is more dangerous.

In view of this, it is an urgent problem in the art to provide a water filtering apparatus in which the filter element is more easily replaced and the water remaining in the filter element does not flow easily when the filter element is replaced.

It is an object of the present invention to provide a water filtering apparatus in which the filter element is easily mounted and the water remaining in the filter element does not easily flow down when the filter element is replaced.

In order to achieve the above object, a water filtering apparatus equipped with the filter element of the present invention includes a main body and a main frame. The main frame has a second pivot member pivotally connected to the first pivot member of the main body.

[ As shown in the figure, in the present embodiment, the abutment portion 337 of the main frame 33 is in one with the rack 375 and is adjacent to the end tooth 379. When the main frame 33 is rotated to the second angle A2 with respect to the main body 31 since the rack 375 is fixed to the main frame 33, the latch 351 moves from the through hole 311 to the inside The main frame 33 is fixed to the second angle A20 by abutting against the abutment portion 337 which is one with the rack 375 of the main frame 33 by sliding.

Preferably, the fastening device 35 comprises two latches 351 on the first side 3a and the second side 3b opposite the water filtering device 3, The through holes 311 are correspondingly formed in the main body 31 of the first side 3a and the second side 3b and the through holes 311 are formed in the main frame 33 of the first side 3a and the second side 3b Two abutment portions 337 are formed correspondingly. The two latches 351 are engaged with the two through holes 311 of the main body 31 when the main frame 33 is rotated to the second angle A2 for replacing the filter element 4 with respect to the main body 31. [ So that the main frame 33 is fixed to the second angle A2 by abutting against the two abutment portions 337 of the main frame 33, respectively.

The water filtering device 3 according to the present invention is characterized in that the main frame 33 is entirely rotated with respect to the main body 31 at the second angle A2 and the filter element 4 is moved to the outside of the main body 31 The fixing device 35 fixes the main frame 33 to the second angle A2 via the rotation preventing device 37 when the protruding member 37 is protruded so that the filter element 4 can be easily replaced. When the filter element 4 of the water filtering device 3 according to the present invention is replaced, the inlet 41 and the outlet 43 of the filter element 4 are directed substantially upward, The water remaining in the filter element 4 does not flow down easily when the filter element 4 is separated from the mounting portion 331 in the downward direction.

The embodiments described above are preferred embodiments of the present invention, but the present invention is not limited thereto. It will be apparent to those skilled in the art that other embodiments may be readily devised by referring to the embodiments described above.
