Description

Technical Field

[0001] The utility model relates to the field of bathtub accessories, in particular to a flow channel structure head built into a bathtub faucet. Background Art

[0002] A bathtub is a water container primarily used for bathing or showering, typically found in bathrooms. It's often fitted with a faucet, a common term for a water valve used to control the flow and temperature of water. The earliest faucets were typically made of alloy or copper, with the flow channel molded directly into the faucet. Due to the excellent thermal conductivity of alloy or copper, hot water flowing through them could easily overheat the faucet's surface during use, posing a safety hazard and potentially scalding the user. Consequently, scald-resistant faucets were introduced.

[0003] For example, Chinese invention patent application number 202010407462.0 (publication number CN113669482 A), titled "Scalding-Proof Bathtub Faucet," discloses a scalding-proof faucet comprising a faucet housing and an inner water flow assembly. The inner water flow assembly is fixedly attached to the faucet housing and includes a first pin, a second pin, a water flow pipe, and a water outlet pipe body, each of which is formed separately. The water flow pipe body includes an integrally formed first water flow pipe body, a second water flow pipe body, and a mixing chamber connecting the two water flow pipe bodies. The first water flow pipe body is sealedly connected to the first pin, the second water flow pipe body is sealedly connected to the second pin, and the water outlet pipe body is sealedly connected to the mixing chamber. A first valve core passes through the faucet housing and is assembled with the first pin, while a second valve core passes through the faucet housing and is assembled with the second pin. A gap is defined between the inner water flow assembly and the faucet housing, allowing air to be trapped in the gap, thereby achieving heat insulation and scalding protection.

[0004] However, this faucet with anti-scalding function also has some problems. Since the relative size of the internal water flow component here is fixed after assembly, it can only be adapted to faucet shells of fixed shape or size. If the distance between the faucet water outlet and the wall needs to be increased, it is necessary to replace the faucet shell with a different water outlet length, and the corresponding internal water flow component must also be replaced as a whole, which increases the replacement cost and causes excessive waste.

[0005] Therefore, how to provide a compact and reasonable structure, and to adjust the assembled size of the inner water flow component as needed, so that it can be quickly adapted to faucet housings of different shapes or sizes, is an urgent problem that technicians in this field need to solve.
