Description

Technical Field

[0001] This utility model relates to an improved invention of a filter, and more particularly to an improved invention of a pre-extracted water filter. Background Technology

[0002] Existing pre-extraction water filters mostly adopt a tank structure, with filter cartridges used for filtration inside the tank. The filter cartridges have a small filtration area and high filtration precision, resulting in low filtration efficiency. Moreover, replacing filter cartridges in tanks is complicated, time-consuming, and labor-intensive. However, the filtration precision requirements for pre-extraction water are not high; instead, more emphasis is placed on filtration efficiency and convenience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pre-extraction water filter.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the pre-extraction water filter includes a cylinder and an end cap, the end cap being provided with a material inlet, characterized in that: a filter basket is provided inside the cylinder, both the bottom of the filter basket and the cylinder are set with a conical structure, and the filter basket and the cylinder are arranged coaxially and at intervals; the upper end of the filter basket is provided with two inverted U-shaped handles symmetrically arranged front and back, the inverted U-shaped handles extending out of the upper port of the cylinder, and the corresponding end cap is provided with an opening.

[0005] The end cap has no sealing gasket, and a planar seal is used between the end cap and the cylinder.

[0006] The end cap is provided with symmetrical handles, with the two handles located between two inverted U-shaped handles.

[0007] The material inlet is formed by hollowing out the outer circle of the end cap to the center.

[0008] The filter basket is provided with an upper support ring on the outer side at the upper end, and a lower support ring is provided on the inner wall of the corresponding cylinder. The upper support ring and the lower support ring are in support cooperation.

[0009] The beneficial effects of this utility model are that the improved pre-extraction water filter adopts a filter basket with a large flow rate in the atmospheric pressure system. The filter basket and the bottom of the cylinder are designed with a conical structure. The conical flow guiding structure can effectively increase the flow rate of the pre-extracted water under atmospheric pressure conditions. The end cap adopts a flat seal, which can economically and effectively block the medium and prevent it from splashing out. The filter basket is equipped with a handle, making replacement and cleaning extremely convenient. Attached Figure Description

[0010] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] Figure 2 This is a top view of the structure of this utility model.

[0013] Figure 3 This is a structural diagram of the end cap of this utility model.

[0014] Figure 4 This is a side view of the end cap of this utility model. Detailed Implementation

[0015] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figure 1-4 The pre-extraction water filter includes a cylindrical body 1 and an end cap 2. The end cap 2 is provided with a material inlet 3. The cylindrical body 1 is provided with a filter basket 4. The bottom of both the filter basket 4 and the cylindrical body 1 is set with a conical structure 5. The filter basket 4 and the cylindrical body 1 are arranged coaxially and at intervals to effectively improve the flow rate of the pre-extracted water under normal pressure conditions. The upper end of the filter basket 4 is provided with two symmetrical inverted U-shaped handles 6. The inverted U-shaped handles 6 extend out of the upper port of the cylindrical body 1, and the corresponding end cap 2 is provided with an opening, so that the filter basket 4 and the end cap 2 can be lifted together, making replacement and cleaning more convenient.

[0016] As a further improved specific implementation, the end cap 2 is not equipped with a sealing gasket, and a planar seal is used between the end cap 2 and the cylinder 1 to economically and effectively block the medium from splashing out.

[0017] As a further improved specific implementation, the end cover 2 is provided with symmetrical handles 7, with the two handles 7 located between two inverted U-shaped handles 6, which facilitates opening the end cover 2.

[0018] As a further improved specific implementation, the material inlet 3 is hollowed out from the outer circle to the center of the end cover 2, that is, it passes through the outer circle. When the feed pipe extends into the material inlet 3, the end cover 2 can be opened without restriction.

[0019] As a further improved specific implementation, the filter basket 4 is provided with an upper support ring 7 located on the outer side at the upper end, and a lower support ring 8 is provided on the inner wall of the corresponding cylinder 1. The upper support ring 7 and the lower support ring 8 support each other, so that the filter basket 4 can be quickly assembled into place in the cylinder 1 and is easy to lift.

[0020] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
