Description

Technical Field

[0001] The utility model belongs to the technical field of faucet accessories and relates to a new inner core structure of a faucet. Background Art

[0002] The faucet consists of a shell, a built-in thermostatic valve core, a handle and other structures. It is an indispensable sanitary ware for every household.

[0003] The faucet shell material usually contains lead, and water directly contacts the faucet shell for a long time. If used or even ingested by the human body, it will endanger human health.

[0004] Currently, two solutions are generally used to solve this problem:

[0005] 1. Replace the shell material with copper. Copper shells are harmless to human health for normal use, but the cost of copper is high, resulting in high replacement and maintenance costs, and affecting the sales stability of the faucet market;

[0006] 2. The valve core structure is installed in the shell. The water flows directly through the valve core structure without passing through the shell. However, the valve core structures paired with different faucet shells are different, which means that the valve core structure is not universal. If the valve core structure needs to be replaced later, the entire faucet must be replaced, which increases the replacement cost and is inconvenient to maintain. Summary of the Invention

[0007] The purpose of the utility model is to address the above-mentioned problems existing in the prior art and to provide a new inner core structure of a faucet which has high versatility, is safe for water flow, and is easy to maintain in the later stage.

[0008] The purpose of the utility model can be achieved through the following technical solutions: A new inner core structure of a faucet, characterized in that the inner core structure includes an inner core shell and a core tube, the inner core shell has a first water inlet, a first water outlet, a second water inlet and a second water outlet, and the core tube is positioned and connected to the inner core shell.

[0009] In the above-mentioned novel inner core structure of a faucet, the inner core shell includes an inner core base and an inner core top cover pressed onto the inner core base.

[0010] In the above-mentioned new inner core structure of a faucet, a mounting groove is provided on the inner core base, the end of the core tube has a mounting portion fitted into the mounting groove, and the inner core top cover is pressed onto the inner core base to prevent the mounting portion from falling off.

[0011] In the above-mentioned novel inner core structure of a faucet, the inner core top cover positions the core tube in the installation groove through a snap-fit ​​structure.

[0012] In the above-mentioned new inner core structure of a faucet, the snap-in structure includes a clamping block located on the top seat of the core tube, and a clamping slot for the clamping block to be clamped into the mounting portion is provided on the mounting portion. The clamping slots are respectively provided on both sides of the mounting portion, and the clamping block is arranged at the bottom of the inner core top cover and at the clamping slot position corresponding to the core tube.

[0013] In the above-mentioned novel inner core structure of a faucet, the inner core base has a water outlet channel connecting the second water outlet and the core tube, and the mounting portion has a water flow channel connecting the water outlet channel and the core tube.

[0014] In the above-mentioned novel inner core structure of a faucet, a positioning hole is provided on the inner core shell.

[0015] In the above-mentioned novel inner core structure of a faucet, the bottom of the inner core top cover is provided with a protrusion, and the inner core base is provided with a groove for installing the protrusion.

[0016] In the above-mentioned novel inner core structure of a faucet, the mounting portion is sealed and mounted in the mounting groove of the inner core base.

[0017] In the above-mentioned novel inner core structure of a faucet, the inner core shell is made of POM polyoxymethylene material.

[0018] Compared with the existing technology, the new inner core structure of the faucet has the following advantages:

[0019] 1. The material is harmless and the water is safe to use;

[0020] 2. The structure is easy to connect and disassemble;

[0021] 3. High versatility, it is connected to the thermostatic valve core with its own positioning feet, so there is no need to replace the entire faucet when replacing it. BRIEF DESCRIPTION OF THE DRAWINGS
