Problems solved by technology
[0003] When used in cold winter areas in the north, the water in the cup of the pre-filter freezes, and the volume expands and squeezes the cup of the filter. However, the structure of the existing cup is limited, and it is easy to cause pre-filter damage after repeated freezing and thawing. The cup of the filter bursts, and eventually the entire pre-filter is scrapped, resulting in a short service life of the pre-filter

Abstract
The invention discloses an anti-freezing cup and a filter. The anti-freezing cup comprises a hollow cup body. The cup body comprises a first mounting portion, a second mounting portion and a main body. The main body is fixedly arranged on the first mounting portion and the second mounting portion, and comprises at least three protruded bodies and recessed bodies. The protruded bodies are recessedinwards, and are same as the recessed bodies in quantity. One recessed body is arranged between every two adjacent protruded bodies. The protruded bodies and the corresponding recessed bodies are arranged sequentially in an encircling mode to form a cavity. The first mounting portion is provided with a fitting hole communicated with one end of the cavity. A sewage drain hole communicated with theother end of the cavity is formed in the second mounting portion. The anti-freezing cup and the filter have the advantages of high anti-freezing capability and prolonged service life of the filter.
Description
technical field [0001] The invention relates to the technical field of water purification equipment, in particular to an antifreeze cup body and a filter. Background technique [0002] The pre-filter is installed in the front section of the pipeline (usually outside the user's door) to filter and purify water. The cup body of the pre-filter is mostly made of engineering plastics such as PC (Polycarbonate, polycarbonate) and PA (Polyamide, nylon or polyamide), and is made into a transparent cup body structure, which is convenient for observing the internal condition of the filter. [0003] When used in cold winter areas in the north, the water in the cup of the pre-filter freezes, and the volume expands and squeezes the cup of the filter. However, the structure of the existing cup is limited, and it is easy to cause pre-filter damage after repeated freezing and thawing. The cup body of the filter bursts, and eventually the entire pre-filter is scrapped, resulting in a short ...
