Technical Field

[0001] The utility model relates to the technical field of water treatment devices, in particular to a liquid inlet anti-scaling filtering device. Background Art

[0002] Humans have been treating water for many years. Physical methods include using filter elements with different pore sizes to remove impurities from the water through adsorption or barrier methods. Existing filter elements are prone to size errors during processing, resulting in excessive squeezing of the filter elements during installation. Due to the different sizes of the devices, not only will there be size mismatch problems, but after long-term operation, the filter element structure is prone to breakage and deformation, resulting in a decrease in anti-scaling filtration effect. Utility Model Content

[0003] In view of the above problems, the utility model proposes a liquid inlet anti-scaling filtering device, which is convenient for the installation of the filter element, avoids the problem of filter element structure breakage during installation, and has a stable anti-scaling filtering effect.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: it includes a shell, an upper cover and a filter element, a support panel for fixing the filter element is arranged in the shell, a telescopic assembly is arranged on the support panel, the telescopic assembly includes a sliding part, a clamping sleeve and an elastic member, the sliding part is arranged in a sliding state toward the axis of the support panel, the clamping sleeve is fixed to the outer peripheral surface of the support panel by a bolt connection, the elastic member is clamped between the sliding part and the clamping sleeve, and the filter element is arranged in a vertical state through the support panel and pressed against the sliding part.

[0005] By adopting the above technical solution, the filter element is installed on the support panel. When the filter element is inserted into the sliding part, the elastic part is compressed and prompts the sliding part to give way to the side close to the shell, so that the filter element can move downward to form a connection. The elastic part is supported by the sleeve and the elastic part releases the contraction pressure to reset. The filter element and the sliding part form a limited abutment, and the upper cover is closed to form a matching installation with the filter element, which reduces the risk caused by processing errors and avoids excessive extrusion of the filter element during installation, which may cause the filter element structure to break, and has a stable anti-scaling filtration effect.

[0007] By adopting the above technical solution, the filter element passes through the plug-in slot and forms a tight contact with the sliding part. The sliding part compresses the elastic member to achieve telescopic concession to one side of the shell, so that the sliding part can form a concession space in the sliding slot, thereby allowing the filter element to achieve downward matching displacement in the plug-in slot, avoiding structural breakage during the installation process.

[0008] The utility model is further configured such that the sliding portion is provided with an abutting flange inclined toward one side of the plug-in slot, an extended support leg is provided on the outer peripheral surface of the sliding portion, a positioning track adapted to the extended support leg is opened in the sliding slot, and the extended support leg is slidably arranged in the positioning track.

[0009] By adopting the above technical solution, the filter element is inserted and displaced downward, and the abutting flange is used to transmit the force, so that the sliding part cooperates with the elastic part to form a telescopic operation in the sliding groove, which can better form a plug-in fit with the filter element. The setting of the extended support leg can improve the smoothness of the telescopic operation, and cooperate with the positioning track to further improve the stability during operation.

[0011] By adopting the above technical solution, the ferrule can be tightened with the positioning slot by means of bolts, wherein the rectangular opening can play a role in sharing the deformation pressure during the installation process of the ferrule, thereby avoiding deformation and breakage of the structure.

[0012] The utility model is further configured such that a support flange is provided on the inner circumference of the sleeve toward the sliding portion, and a telescopic groove is provided on the sliding portion toward the support flange.
