Technical Field
[0001] The utility model relates to the field of shower faucets, and particularly to an anti-freezing shower faucet. Background Art
[0002] A shower faucet is a kind of sanitary ware, mainly installed in the bathroom for people to use when taking a shower. Nowadays, a shower faucet usually consists of a plastic inner core and a housing assembled together, which has better economy compared with the scheme of integral metal forming. However, the strength of the plastic inner core is relatively low. When the water cavity is sealed inside, the volume expansion of the flowing water when it freezes easily cracks the plastic inner core, resulting in water leakage and failure of the inner core.
[0003] In view of this, the inventor of the present case deeply studied the above-mentioned defects in the prior art, and thus this case was born. Summary of the Utility Model
[0004] The main purpose of the utility model is to provide an anti-freezing shower faucet, which has the advantages of buffering the expansion pressure during freezing and avoiding the cracking and failure of the faucet.
[0005] In order to achieve the above object, the solution of the utility model is:
[0006] An anti-freezing shower faucet, which includes a housing, an inner core and a pressure relief valve; the inner core is installed in the housing, and the inner core includes a cold water channel, a hot water channel, a mixing channel and a plurality of water outlet channels; the cold water channel and the hot water channel are respectively communicated with a temperature control valve core, the temperature control valve core is installed between the cold water channel and the mixing channel, and a control valve core with a quantity matching the number of the water outlet channels is installed between the mixing channel and the water outlet channels; pressure relief valves are respectively installed in the cold water channel and the mixing channel.
[0007] Further, the pressure relief valve includes a moving head, a fixed head and a spring; the fixed head is fixedly connected with the inner core, the moving head is slidably and sealingly installed in the cold water channel and the mixing channel, and the spring is installed between the moving head and the fixed head.
[0008] Further, a guiding column is formed at one end of the fixed head, a guiding hole is formed at one end of the moving head, and two ends of the spring are respectively inserted into the guiding column and the guiding hole.
[0009] Further, a sunk groove is formed around the guiding column, and one end of the spring is inserted into the sunk groove.
[0010] Further, a sealing groove is formed on the moving head, and a sealing ring is installed in the sealing groove.
[0011] Furthermore, a clamping groove is formed on the inner core, and a clamping block is formed on the fixing head, and the clamping block is clamped in the clamping groove.
[0012] Furthermore, a guide groove leading to the clamping groove is formed on the inner core.
[0013] Furthermore, a butting step is formed on the inner core, and one end of the movable head away from the fixed head butts against the butting step, and the spring is pre-tightened and installed between the fixed head and the movable head.
[0014] Furthermore, a tooling hole is formed on the fixing head.
[0015] Furthermore, when the movable head is subjected to water flow pressure, it does not abut against the fixed head.
[0016] After adopting the above structure, the anti-freeze cracking shower faucet of the utility model has at least the following beneficial effects:
[0017] 1. When in use, the cold water channel and the mixed water channel are filled with water. When the temperature is too low, the water in the cold water channel and the mixed water channel will freeze and increase in volume. Through the deformation of the pressure relief device, there is enough space to accommodate the expanded volume of the water after freezing, avoiding the inner core from being squeezed and cracked, thereby greatly improving the stability of the product.
[0018] Second, when water freezes, it will squeeze the moving head, and the moving head can transfer pressure to the spring, causing the spring to deform, and the moving head displacement creates enough space to accommodate the volume of frozen water. The buffering of the spring can also reduce the impact of the water hammer effect on the inner core during the use of the faucet.
[0019] 3. Through the guiding effect of the guide column and the guide hole, the lateral deformation failure of the spring can be avoided, and the stability of the product is further improved. The guide column can be inserted into the guide hole, which allows the spring to have a longer compression stroke.
[0020] Compared with the prior art, the utility model provides an anti-freezing and cracking shower faucet, which can make room for expansion of the outlet water when it freezes by changing the position of the moving head, thereby avoiding the inner core from being squeezed and cracked, and greatly improving the stability of the product.

[0032] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail through specific embodiments below.
[0033] As Figures 1 to 4 shown, it is an anti-freezing and cracking shower faucet related to the present utility model, including a housing 1, an inner core 2 and a pressure relief valve 3; the inner core 2 is installed in the housing 1, and the inner core 2 includes a cold water channel 21, a hot water channel 22, a mixed water channel 23 and a plurality of water outlet channels 24; the cold water channel 21 and the hot water channel 22 are respectively communicated with the temperature control valve core 4, the temperature control valve core 4 is installed between the cold water channel 21 and the mixed water channel 23, and a control valve core 5 with a quantity matching the number of the water outlet channels 24 is installed between the mixed water channel 23 and the water outlet channels 24; pressure relief valves 3 are respectively installed in the cold water channel 21 and the mixed water channel 23. When in use, the cold water channel 21 and the mixed water channel 23 are in a water-filled state. In the case of too low temperature, the water in the cold water channel 21 and the mixed water channel 23 will freeze and the volume will increase. Through the deformation of the pressure relief valve 3, there is enough space to accommodate the expanded volume of the water after freezing, avoiding the situation that the inner core 2 is squeezed and cracked, and greatly improving the stability of the product.
[0034] Preferably, as Figure 2 and Figure 3As shown, the pressure relief valve 3 includes a moving head 31, a fixed head 32, and a spring 33; the fixed head 32 is fixedly connected to the inner core 2, the moving head 31 is slidably and sealingly installed in the cold water channel 21 and the mixing water channel 23, and the spring 33 is installed between the moving head 31 and the fixed head 32. After the water freezes, it will squeeze the moving head 31, and the moving head 31 can transfer the pressure to the spring 33, causing the spring 33 to deform. The displacement of the moving head 31 generates enough space to accommodate the volume of the frozen water flow. And through the buffering of the spring 33, the impact of the water hammer effect on the inner core 2 during the use of the faucet can also be reduced.
[0035] Preferably, a guiding column 321 is formed at one end of the fixed head 32, a guiding hole 311 is formed at one end of the moving head 31, and both ends of the spring 33 are respectively inserted into the guiding column 321 and the guiding hole 311. Through the guiding action of the guiding column 321 and the guiding hole 311, the lateral deformation failure of the spring 33 can be avoided, further improving the stability of the product. The guiding column 321 can be inserted into the guiding hole 311, which enables the spring 33 to have a longer compression stroke. In addition, a sunk groove 322 is formed around the guiding column 321, and one end of the spring 33 is inserted into the sunk groove 322. Preferably, a sealing groove 312 is formed on the moving head 31, and a sealing ring 313 is installed in the sealing groove 312.
[0036] Preferably, as Figure 1 and Figure 2 shown, a clamping groove 25 is formed on the inner core 2, a clamping block 323 is formed on the fixed head 32, the clamping block 323 is clamped in the clamping groove 25, and a guiding groove 26 leading to the clamping groove 25 is also formed on the inner core 2. In this way, when installing the fixed head 32, the clamping block 323 can be inserted along the guiding groove 26, and then rotated by a certain angle so that the clamping block 323 and the clamping groove 25 are clamped, fixing the fixed head 32 on the inner core 2.
[0037] Preferably, an abutting step 27 is formed on the inner core 2, one end of the moving head 31 away from the fixed head 32 abuts against the abutting step 27, and the spring 33 is pre-tensioned and installed between the fixed head 32 and the moving head 31. Through the limitation of the abutting step 27, the sliding of the moving head 31 beyond the working range can be prevented to avoid the failure of the pressure relief valve 3.
[0038] Preferably, a tooling hole 324 is also formed on the fixed head 32, and the tooling hole 324 is an internal hexagonal hole, which is convenient for the user to turn the fixed head 32 with a hexagonal wrench.
[0039] Preferably, when the moving head 31 is under the water flow pressure, it does not abut against the fixed head 32. This ensures that there is still a yielding space between the moving head 31 and the fixed head 32 when the water freezes.
[0040] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
