Background

Before tap water reaches a water terminal through a water supply network, a plurality of pipelines are provided, and impurities such as a plurality of silt, rust, suspended matters and the like exist in the pipelines, if no filtering treatment is performed, secondary pollution of the tap water can be caused.

The pre-filter is used as a first filtering device of a water terminal, and can filter the sediment, rust, ova, red worms and other large-particle substances in tap water. Therefore, the prior waterway system mostly adopts a pre-filter to filter water at the source before entering the water terminal, so that the secondary pollution can be effectively eliminated, the water pollution disease is reduced, the solid impurities can be removed, the waterway system is protected, and the system maintenance cost is reduced.

Currently, in practical applications, the pre-filter is generally installed in two ways:

1. in the concealed installation mode, the pre-filter is arranged at a concealed corner such as a kitchen. The installation mode has the advantages of saving living space and enabling the whole home decoration effect to be more attractive, but has the defect of inconvenient installation and operation.

2. In the open mounting mode, the pre-filter is arranged outside the wall body. The installation mode has the advantages of being convenient to install and operate, but has the defects of occupying living space and affecting the overall home decoration effect.

In the practical application process, the pre-filter can obviously find that the water flow is smaller when two water taps are opened at the same time because the water flow is low and the water flow is small when the pre-filter is installed. Therefore, the matched supercharging device is needed in the use of the pre-filter, the requirement on space is high no matter the above-mentioned open mounting or installation mode is adopted, and the supercharging device is additionally added, so that larger space is required to be occupied, and meanwhile, no matter the open mounting or installation mode is adopted, noise is brought to the surrounding environment due to the addition of the supercharging device.

Detailed Description

The technical scheme of the utility model is further described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the prefilter of the present utility model includes a prefilter body and a universal valve 13 provided at an upper end of the prefilter body. The prefilter body comprises a shell 1 and an end cover 2 arranged at the upper end of the shell 1. The housing 1 is provided with a cavity for accommodating the filter element 3, and the filter element 3 can be a single filter element or a composite filter element which is known in the art, and can be selected according to actual requirements without specific limitation. A water inlet cavity is formed between the outer side wall of the filter element 3 and the inner side wall of the shell 1, and a filtered water channel 4 is formed in the inner side cavity of the filter element 3, as shown in fig. 2.

As shown in fig. 2, the joint of the end cover 2 and the universal valve 13 is provided with a water inlet channel 5 and a water purifying channel 6.
