Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a faucet waterway structure. Background Art

[0002] Shower faucets generally have a temperature control switch and a water outlet switch, and there are many styles. To ensure water use safety, many shower faucets separately arrange the water outlet switch (or flow control switch) and the temperature control switch at the left and right ends of the faucet, so as to separate and distance the two switches as much as possible and prevent error situations. In some shower areas with small spaces, consumers hope that the length of the shower faucet can be shorter to maintain the coordination between the size of the shower faucet and the space size of the shower area. Or, some consumers like shower faucets with small sizes, believing that long faucets not only have disproportionate self-proportions but also occupy space. However, the shower faucets with the above structure are generally in a linear shape and horizontally installed, with a relatively long overall length. It is difficult to select a style that meets the above scenarios or consumer needs, resulting in limited choices of faucets for the above scenarios or consumers. Therefore, the utility model provides a faucet waterway structure with a shorter size, so that a linear shower faucet with a shorter length can be made, providing more choices for consumers. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model proposes a faucet waterway structure with a shorter size.

[0004] A faucet waterway structure includes a faucet body. The faucet body is columnar, with a water outlet installation cavity at one end and a temperature adjustment installation cavity at the other end. Inside the faucet body, there are a hot water channel, a cold water channel, a mixed water channel, and a water outlet channel.

[0005] The water inlet end of the hot water channel forms a hot water inlet on the circumference of the faucet body, and the water outlet end forms a hot water outlet on the outer circumference of the temperature adjustment installation cavity. The water inlet end of the cold water channel forms a cold water inlet on the circumference of the faucet body, and the water outlet end forms a cold water outlet on the outer circumference of the temperature adjustment installation cavity. The water inlet end of the mixed water channel forms a mixed water inlet at the end of the temperature adjustment installation cavity, and the water outlet end forms a mixed water outlet on the circumference of the water outlet installation cavity. The water inlet end of the water outlet channel is communicated with the end of the water outlet installation cavity, and the water outlet end forms a shower water outlet on the circumference of the faucet body.

[0006] The hot water inlet is arranged close to the water outlet installation cavity, and the partition where the bottom of the groove of the water outlet installation cavity is located extends to the hot water inlet, and the hot water inlet forms a special-shaped opening with a flush edge. The mixed water inlet is oval, and the longer diameter is perpendicular to the axis of the faucet body. Thus, the distance from the water outlet installation cavity to the midpoint between the hot water inlet and the cold water inlet can be shortened, avoiding excessive length of the faucet body.

[0007] The cold water inlet is arranged close to the temperature adjustment installation cavity, and the temperature adjustment installation cavity extends towards the middle of the faucet body and exceeds the cold water inlet. The cold water inlet adopts a strip-shaped opening perpendicular to the axial direction of the faucet body. The cold water outlet is also oval, and the longer diameter is perpendicular to the axis of the faucet body. Thus, the distance from the temperature adjustment installation cavity to the midpoint between the hot water inlet and the cold water inlet can be shortened, avoiding excessive length of the faucet body.

[0008] For the faucet waterway structure provided by the present utility model, the valve core installation cavities at both ends of the faucet body are both inwardly contracted. Without affecting the water inflow, by occupying part of the space of the hot water inlet and the cold water inlet, and setting an oval mixed water inlet and a cold water outlet, the distance from both ends of the faucet body to the midpoint between the hot water inlet and the cold water inlet is controlled. Thus, a faucet waterway structure and a faucet body with a shorter overall length can be formed, and then a shower faucet with a shorter overall length can be manufactured to meet the needs of some consumers and provide more choices for consumers.

[0009] Preferably, curved foot limit grooves are provided on the peripheries of the hot water inlet and the cold water inlet, which are used in cooperation with the curved feet during the installation of the shower faucet.

[0010] Preferably, a flow-cutting valve core is installed in the water outlet installation cavity. There are two water outlet channels, one end of each is communicated with the water outlet installation cavity, and the other end of each is provided with its own shower water outlet, so that the faucet waterway structure can switch the water outlet to provide different shower requirements for users.

[0011] Preferably, the two shower water outlets are respectively arranged on the upper and lower sides of the faucet body and are coaxial.

[0012] Preferably, the two water outlet channels are close to each other and arranged parallel up and down, and are arranged between the hot water channel and the mixed water channel. The layout is reasonable and the structure is compact, avoiding waste of space and avoiding increasing the diameter of the faucet body.

[0013] Preferably, the faucet body is an injection-molded part, and an insert nut is provided in the shower water outlet. On the one hand, the docking firmness between the shower water outlet and the joint can be improved, and on the other hand, the subsequent assembly steps can be reduced.

[0014] Preferably, the flow-cutting valve core is pressed by a gland, and the gland is assembled with the end of the faucet body through threads. The inner ring of the opening of the water outlet installation cavity is chamfered, and a pressed sealing ring is provided between the opening of the water outlet installation cavity, the gland and the flow-cutting valve core. On the basis of achieving sealing, the configuration of the sealing ring can be reduced.

[0015] Preferably, a gear position pin structure is provided in the flow-cutting valve core, which can stabilize the current gear position and also provide a better switching feel.

[0016] Preferably, to avoid the high forming difficulty of the faucet body, an insertion pipe is further included. The temperature adjustment installation cavity is arranged inside the insertion pipe, and the insertion pipe is inserted into the end of the faucet body, and the end is hermetically docked with the mixed water channel. There is a gap between the middle of the insertion pipe and the inner wall of the faucet body, and the gap is divided into the end of the hot water channel and the cold water channel by a sealing ring. The insertion pipe is provided with a hot water outlet and a cold water outlet corresponding to the end of the hot water channel and the cold water channel.

[0017] Preferably, a thermostatic valve core is installed inside the insertion pipe to provide a thermostatic shower experience for users, and a child lock is provided on the switch of the thermostatic valve core to improve the water use safety.

[0018] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0019] The faucet waterway structure provided by the present invention has the valve core installation cavities at both ends of the faucet body both contracting inward. Without affecting the water inflow, by occupying part of the space of the hot water inlet and the cold water inlet, and setting an oval mixed water inlet and a cold water outlet, the distance from both ends of the faucet body to the midpoint between the hot water inlet and the cold water inlet is controlled, so that a faucet waterway structure and a faucet body with a shorter overall length can be formed. Furthermore, a shower faucet with a shorter overall length can be manufactured to meet the needs of some consumers and provide more choices for consumers;

[0020] The two outlet channels are close to each other and arranged parallel up and down, and are arranged between the hot water channel and the mixed water channel. The layout is reasonable and the structure is compact, avoiding waste of space and avoiding making the diameter of the faucet body larger;
