Description

Technical Field

[0001] The utility model relates to the technical field of faucet accessories, in particular to a water distribution core of a shower faucet. Background Art

[0002] After using a traditional shower faucet, there is often undischarged water remaining in the inner cavity. In a cold environment, affected by the external low temperature environment, the water remaining in the faucet cavity is easy to freeze. Since the freezing process is a process of volume expansion, the ice formed in the inner cavity will squeeze the inner cavity outward, and the main body is generally made of plastic, which has poor ability to withstand freezing expansion, resulting in a greater risk of cracking of the main body. Utility Model Content

[0003] Based on the above problems, the utility model provides a water distribution core of a shower faucet which has a simple structure and can effectively prevent the main body from freezing and cracking.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water distribution core of a shower faucet, comprising a main body, a cold water inlet and a hot water inlet are respectively arranged at the rear end of the main body, a mixing water chamber is arranged at one end in the length direction of the main body, the cold water inlet and the hot water inlet are respectively connected to the mixing water chamber through a cold water inlet channel and a hot water inlet channel, a plurality of water outlets are arranged at the front end of the main body, the mixing water chamber is connected to the water outlets through a water diversion channel, a first pressure relief channel is arranged at the other end of the hot water inlet channel relative to the mixing water chamber, and the The first pressure relief channel is coaxially arranged with the hot water inlet channel and is communicated with the same, a first pressure relief assembly is arranged in the first pressure relief channel, the first pressure relief assembly includes a sealing plug, a spring and a plug, a mounting hole is opened at one end of the first pressure relief channel facing away from the hot water inlet channel, the plug closes the mounting hole and is fixed in the mounting hole through a connecting piece, the sealing plug is slidably arranged in the first pressure relief channel and seals with the inner wall of the first pressure relief channel, the spring is arranged between the sealing plug and the plug and one end of the spring is connected to the sealing plug, and the other end is connected to the plug.

[0005] By adopting the above technical scheme, a thermostatic switch is arranged in the mixing chamber. When the thermostatic switch is closed, water will remain in the inner cavity of the cold water inlet channel and the hot water inlet channel. In a cold environment, the residual water in the inner cavity of the hot water inlet channel will freeze into ice. The arrangement of the first pressure relief component allows the sealing plug in the first pressure relief channel to be squeezed by the expansion of ice, and can push the spring to compress it, provide expansion space for ice, release expansion pressure, and avoid the expansion of ice exerting pressure on the inner wall of the inner cavity to cause it to freeze and crack. When the ice melts, the spring drives the sealing plug to reset, automatically preventing freezing and cracking, and improving structural reliability. The hot water inlet is far away from the mixing chamber, so that the length of the hot water inlet channel from the mixing chamber is long, and the expansion pressure of water after freezing is large. Therefore, the first pressure relief component is arranged at the other end of the hot water inlet channel relative to the mixing chamber. The structural distribution is reasonable and it is more convenient to process. There are multiple water outlets. The user can control and open the switch arranged at the corresponding water outlet position according to the use requirements, so that it controls the corresponding water outlet to perform water discharge operation, thereby improving the practicality of the structure.

[0006] The utility model is further provided that: the connecting member comprises a pin shaft, and the first pressure relief channel and the plug are both provided with vertical pin holes, and the pin shaft is fixedly connected with the two by plugging into the pin hole.

[0007] By adopting the above technical solution, when the plug is installed to the mounting hole position, the pin hole on the plug position just corresponds to the pin hole on the first pressure relief channel. After the correspondence, the plug is fixed in the mounting hole by the pin shaft, and the structure is stable and easy to install.

[0008] The utility model is further arranged that: a guide column is arranged on the side of the spring facing the plug, and the guide column is arranged coaxially with the spring and is inserted into the spring.

[0009] By adopting the above technical solution, the setting of the guide column plays a guiding role in the deformation of the spring, making it less likely to change direction, be displaced, twist and be damaged, thereby increasing the service life. At the same time, it better cooperates with the sealing plug to expand and contract, and the pressure acts on the sealing plug more stably, making the structure more reliable.

[0010] The utility model is further configured that: the first pressure relief channel and the water inlet channel are integrally formed.

[0011] By adopting the above technical solution, the number of parts is reduced, the production process is simplified, thereby saving costs, and the structure is more stable and convenient to use.

[0012] The utility model is further configured as follows: a second pressure relief channel is provided at the other end of the water diversion channel relative to its water inlet end, the second pressure relief channel is coaxially arranged with the water diversion channel and is connected with the water diversion channel, and a second pressure relief component with the same structure as the first pressure relief component is provided on the second pressure relief channel.

[0013] By adopting the above technical scheme, when the user does not turn off the thermostatic faucet, water will remain in the inner cavity of the water diversion channel, the cold water inlet channel and the hot water inlet channel. In a cold environment, the water at each inner cavity position will freeze into ice. The second pressure relief component having the same structure as the first pressure relief component is also provided, which also includes a sealing plug, a spring and a plug. The sealing plug pushes the spring to compress by squeezing, provides expansion space for ice formation, releases expansion pressure, and prevents the ice expansion from exerting pressure on the inner wall of the inner cavity of the water diversion channel to cause it to freeze and crack. The first pressure relief component and the second pressure relief component are used in a two-pronged manner to further improve the stability of the structure. When the main body is core-pulling, the core is pulled at the other end of the water diversion channel relative to the mixing chamber. The second pressure relief channel is provided at the other end of the water diversion channel relative to the mixing chamber. The plug of the second pressure relief component can replace the plug originally required to close the core-pulling hole. The structural distribution is more reasonable and the production process is simplified. BRIEF DESCRIPTION OF THE DRAWINGS
