Description

Technical Field

[0001] This utility model relates to the field of pre-filter technology, and in particular to a cup structure in a pre-filter. Background Technology

[0002] Currently, pre-filters on the market come in two types: one with a completely transparent cup, which allows you to clearly see the filtered debris, but has the disadvantage of being prone to bursting (many pre-filters are installed under cabinets, and a burst cup can flood the entire room and damage downstairs neighbors). Another type is made of pure copper, which is less prone to bursting, but has the disadvantage of obscuring the internal debris, having a higher lead content than plastic, and lacking sufficient toughness, making it susceptible to cracking at low temperatures. Therefore, it is essential to improve upon the existing defects in pre-filter cups. Summary of the Invention

[0003] The purpose of this invention is to solve the problems mentioned in the background art and to provide a cup structure in a pre-filter.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a cup structure in a pre-filter, including a cup body, a filter element, a three-way connector, and a drain valve; the cup body includes an inner cup body and an outer cup body, the inner cup body is disposed in the outer cup body, the filter element is disposed in the inner cup body, the inner cup body is made of plastic, and the outer cup body is made of metal.

[0005] In the cup structure of the aforementioned pre-filter, the outer cup is provided with multiple observation holes, and the inner cup is provided with an observation part corresponding to the position of the observation holes.

[0006] In the cup structure of the aforementioned pre-filter, the inner cup is a transparent plastic cup, and the outer cup is a copper cup made of metal.

[0007] In the cup structure of the aforementioned pre-filter, the inner cup is formed inside the outer cup by injection molding.

[0008] In the cup structure of the aforementioned pre-filter, one end of the inner cup is connected to the drain valve, and one end of the outer cup is connected to a three-way connector.

[0009] In the cup structure of the aforementioned pre-filter, the inner cup and the outer cup are respectively provided with a connecting groove and a connecting boss at their mating ends. The end of the outer cup is embedded in the connecting groove, and the end of the outer cup is also provided with a connecting groove that mates with the connecting boss.

[0010] In the cup structure of the aforementioned pre-filter, the end of the inner cup that connects to the drain valve is located at the end of the outer cup.

[0011] In the cup structure of the aforementioned pre-filter, a sealing ring is provided between one end of the inner cup and the three-way connector.

[0012] The beneficial effects of this utility model are:

[0013] The cup body of this utility model consists of two parts: an inner cup body and an outer cup body. The inner cup body is a transparent cup body made of plastic, and the outer cup body is a copper cup body made of metal. The inner cup body is formed inside the outer cup body by injection molding. Therefore, the inner cup body plays a good role in lead isolation and environmental protection, and at the same time eliminates the concern of bottle explosion caused by cup bodies made of plastic alone on the market.

[0014] This structure features a transparent inner cup and a transparent observation structure, achieving the need for visualization while ensuring strength and environmental friendliness.

[0015] This structure significantly reduces the amount of metal used in the cup body while ensuring strength, thus saving energy and reducing costs. Attached Figure Description

[0020] The present invention will be further described in conjunction with the accompanying drawings. Example

[0021] Please see Figure 1 , Figure 2 This utility model provides a cup structure in a pre-filter, including a cup body 1, a filter element 2, a three-way connector 3, and a drain valve 4; the cup body 1 includes an inner cup body 5 and an outer cup body 6, the inner cup body 5 is disposed in the outer cup body 6, the filter element 2 is disposed in the inner cup body 5, one end of the inner cup body 5 is connected to the drain valve 4, and one end of the outer cup body 6 is connected to the three-way connector 3. The inner cup body 5 is made of plastic, and the outer cup body 6 is made of metal.

[0022] Furthermore, the inner cup body 5 is a transparent cup body made of plastic, and the outer cup body 6 is a copper cup body made of metal; the inner cup body 5 is formed inside the outer cup body 6 by injection molding.

[0023] The cup consists of two parts: an inner cup and an outer cup. The inner cup is made of transparent plastic, while the outer cup is made of copper. The inner cup is formed inside the outer cup using a mold injection molding process, thus providing excellent lead protection and eliminating concerns about bottle breakage caused by simply using plastic cups on the market.
