Embodiment 2
[0055] The filter device that is easy to install and prevents water leakage described in this embodiment is basically the same as the filter device that is easy to install and prevents water leakage in Embodiment 1, except that: Figure 14 As shown, the connecting block 9 adopts a section in the form of a "comma"; the section in the form of a "comma" has two pushing surfaces 901 and three locking surfaces 902. There are a total of 5 sections in the form of "commas". The "commas" in the sections in the form of "commas" are mirror-symmetrical to the commas in conventional punctuation marks. The 5 "commas" sections are set at intervals, and two adjacent "commas One of the tapered parts faces down and the other faces up, and the two outermost tapered parts of all the "commas" face down; the "comma" with the tapered parts facing up is the pushing surface, and the "comma" with the tapered parts facing down is the locking noodle.

The invention provides a filtration apparatus with characteristics of convenient installation and water leakage prevention. The filtration apparatus comprises a shell, a filtration core arranged in the shell, and a base positioned on the bottom portion of the shell, wherein a water inlet pipe and a water outlet pipe are arranged on the top portion of the shell, valve rods capable of moving up anddown are respectively arranged in the water inlet pipe and the water outlet pipe, the upper ends of the valve rods extend into the water inlet pipe and the water outlet pipe, the valve rod parts closeto the top portions of the water inlet pipe and the water outlet pipe are respectively sleeved with a first sealing rubber ring, the middle cross section of the valve rod is +-shaped, the water inletpipe position corresponding to the middle position of the valve rod is provided with a water inlet, the water outlet pipe position corresponding to the middle of the valve rod is provided with a water outlet, the lower ends of the valve rods are snapped at the communication positions between the shell and the water inlet pipe and between the shell and the water outlet pipe, the snapping positionsare provided with second sealing rubber rings, and the valve rod lower end part positioned in the shell is sleeved with a spring. According to the present invention, by arranging the two sealing ribson the bush, the inclined surface sealing can be avoided.
Description
technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a filter device which is easy to install and can prevent water leakage. Background technique [0002] With the development of refrigerator manufacturing technology, refrigeration devices or cold drink preparation devices are often installed in existing refrigerators to provide more choices and convenience for users. In order to facilitate operation, there is also a drinking water supply pipe in the refrigerator, which has provided drinking water for making ice cubes or cold drinks. Due to pollution of the environment due to wastewater discharge and other reasons, the source of drinking water is also affected. In addition, drinking water will also be polluted twice in the transmission path. Therefore, if drinking water is not purified, it will be used directly for ice making or drinking. , is likely to pose a threat to human health. Therefore, water filters f...
