The number of water passing ports 41 of the fixed seat 4 is plural, the water passing ports are in one-to-one correspondence with the water discharging ports 73 of the descaling pieces 7, annular flanges 42 are arranged at the inner ends of the water passing ports 41 of the fixed seat 4 in a protruding mode downwards, the hollow cylinder bodies 74 of the descaling pieces 7 are respectively matched with the inner sides of the annular flanges 42 of the corresponding water passing ports 41, and the hollow cylinder bodies 74 are guided and positioned by the annular flanges 42. The water distribution disc 3 is provided with water flows uniformly, so that water flows are respectively fed into the water passing ports 41 of the fixing seat 4.
The state of the automatic water draining descaling sprinkler is shown in fig. 3 and 4 before water is introduced, and at the moment, each descaling needle 71 of the descaling piece 7 is respectively inserted into a corresponding water outlet hole 81, so that the water outlet hole 81 is blocked; the drainage channel 85 is in an open state, the memory alloy spring 6 is in a cold-shrink state, and the reset spring 5 is in an energy release state. When water is introduced, water flows sequentially through the water inlet channel 11 of the sprinkler body 1, the water distribution disc 3, the water passing port 41 of the fixing seat 4 and the water discharging port 73 of the descaling plate to enter the water outlet cavity 83. When water is just introduced, the water temperature is lower due to residual water in the pipeline, and the descaling piece 7 is still tightly attached to the water outlet cover 8 under the action of the reset spring 5, so that the descaling needle 71 is kept in a state of blocking the water outlet hole 81. Accordingly, the water introduced into the water discharge chamber 83 flows from the water discharge passage 85 to the water discharge chamber 84, and finally flows out of the water discharge chamber 84 as shown in fig. 5. After the residual water in the pipeline is drained, the water temperature gradually rises, when the water temperature exceeds a preset temperature (the preset temperature is 25 ℃ but is not limited to the preset temperature), the memory alloy spring 6 is heated and stretched, so that the descaling piece 7 is lifted upwards against the spring force of the reset spring 5, the descaling needle 71 is separated from the water outlet hole 81, meanwhile, the water retaining part 72 of the descaling piece 7 is lifted along with the descaling piece 7 to close the water drain channel 85, and therefore, water cannot flow out of the water drain hole 82 but only flows out of the water outlet hole 81, and the normal water outlet is realized according to the invention, as shown in fig. 6.
When water is shut off, no water flow enters the water inlet channel 11 of the sprinkler body 1, the memory alloy spring 6 is gradually cooled and contracted, the descaling piece 7 moves downwards under the action of the restoring force of the reset spring 5, so that the descaling needle 71 is inserted into the water outlet hole 81, and impurities in the water outlet hole 81 are discharged, thereby achieving the descaling purpose. As the scale remover 7 moves down, its water blocking portion 72 gradually opens the drain passage 85, ready for the next pre-discharge of cold water.
According to the automatic water draining descaling shower head, when a user uses the shower head, whether the residual cold water is drained can be judged by observing whether the drain holes 82 drain water or not, so that the shower head is very convenient for the user to use.
In other embodiments, the reset mechanism is a magnetic reset mechanism.
The above embodiment is only used for further explaining an automatic water draining descaling shower head of the present invention, but the present invention is not limited to the embodiment, and any simple modification, equivalent variation and modification of the above embodiment according to the technical substance of the present invention falls within the protection scope of the technical solution of the present invention.
