Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a faucet with a novel valve core tube. Background Art

[0002] Most of the existing faucets are cast in one piece. This type of faucet has complex mold requirements and high production costs. After long-term use, it is easy to release heavy metal substances that affect health. For this reason, there are faucets on the market that manufacture the valve core body and the faucet body separately, and then assemble them into a whole at a later time. However, in order to facilitate the installation of the valve core through the valve core gland, this type of faucet often needs to make the faucet body thicker, thereby reserving the thickness of the tapping thread. The material cost is high and the economic benefit is low. Alternatively, the faucet body is manufactured in parts and then welded, which has high requirements on the welding process. If the positioning is insufficient, it is very easy to affect the sealing and cause water leakage. Utility Model Content

[0003] Therefore, in view of the above problems, the utility model provides a faucet with a low production cost and a novel valve core tube.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is to provide a faucet with a new valve core tube, including: a valve core tube, the valve core tube including: an inlet pipe, an outlet pipe, and a valve seat arranged between the inlet pipe and the outlet pipe, the valve seat is detachably provided with a valve core mounting sleeve, and the valve core mounting sleeve is provided with a positioning device for positioning the valve core.

[0005] A further improvement is that: a first connecting thread is provided on the peripheral side of the valve seat, and a second connecting thread matching the first connecting thread is provided on the valve core mounting sleeve.

[0006] A further improvement is that: the positioning device is: a positioning ring for pressing the valve core is arranged inside the valve core installation sleeve, or a plurality of positioning blocks for pressing the valve core are arranged inside the valve core installation sleeve.

[0007] A further improvement is that the water inlet pipe is also provided with a water inlet seat for easy connection with the water delivery pipeline.

[0008] A further improvement is that: a core-pulling hole is provided on the water inlet pipe, a sealing screw is locked in the core-pulling hole, and a sealing ring is provided between the sealing screw and the core-pulling hole.

[0009] A further improvement is that: a connecting ring is integrally formed on the water inlet seat, and a third connecting thread is provided on the connecting ring.

[0010] A further improvement is that a plurality of latch teeth are provided on the outer side of the connecting ring.

[0011] A further improvement is that a faucet shell is sleeved on the valve core tube, a positioning hole is opened on the faucet shell, a water screw passing through the positioning hole is locked on the water inlet pipe, and a water passage connected to the water inlet pipe is opened on the water screw.

[0012] A further improvement is that: the water screw is also provided with a fourth connecting thread.

[0013] A further improvement is that a stop platform is arranged outside the valve core installation sleeve, and the faucet housing and the stop platform resist each other to enhance the positioning of the faucet housing and protect the valve core installation sleeve.

[0014] A further improvement is that: the water inlet pipe is also provided with a plurality of positioning rods for assisting the installation of the faucet housing.

[0015] A further improvement is that a cover plate is also provided at the bottom of the faucet housing, and a avoidance hole is provided on the cover plate to facilitate the connection between the valve core tube and the water supply pipeline.

[0016] A further improvement is that the water inlet pipe includes a cold water inlet pipe and a hot water inlet pipe.

[0017] The advantages and beneficial effects of the utility model are:

[0018] 1. The valve core is fixed by the valve core installation sleeve and the positioning device, so that the thickness of the faucet shell can be selected more freely during production, which reduces material costs and improves economic benefits. Compared with the welding of the faucet shell, the number of positioning times required is reduced. While saving labor costs, it also brings better positioning and sealing, improves the yield rate, and improves economic benefits.

[0019] 2. The faucet shell and the valve core tube are manufactured separately, and the materials are independent of each other, which makes it convenient to use environmentally friendly and harmless materials to manufacture the valve core tube, thereby improving the safety of the faucet.
