Description

Technical Field

[0001] The present invention relates to the technical field of kitchen and bathroom, and in particular to a descaling water outlet device, a shower head and a faucet. Background Art

[0002] The existing descaling water outlet device includes a shower head cover, at least one water inlet, at least one group of main water outlet holes, a group of auxiliary water outlet holes, a switching device, a descaling rack, a pressure plate, and an elastic member. The main water outlet hole and the auxiliary water outlet hole are both provided on the shower head cover, with a main water passage formed between the main water outlet hole and the water inlet, and a driving water passage formed between the auxiliary water outlet hole and the water inlet. One end of the switching device is connected to the water inlet, and the other end is respectively connected to the main water passage and the driving water passage for switching the connection. The descaling rack is provided with a descaling member corresponding to the main water outlet hole. The pressure plate is located in the driving water passage and is fixed to the descaling rack. When water flows through the driving water passage, the pressure plate is pushed by the water pressure to insert the descaling member into the main water outlet hole. The elastic member presses against the shower head cover at one end and against the descaling rack at the other end. When the driving water passage stops flowing, the descaling rack is pushed away from the shower head cover. When the water channel is driven to discharge water, the hydraulic force of the driving water channel drives the descaling rack to insert into the main water outlet hole. When the water is stopped or the main water channel is discharged, the descaling rack is reset by the elastic force of the elastic body. Since the elastic body is used for elastic reset, the control accuracy of the descaling rack activity is low. Summary of the Invention

The main body part 11 and the water outlet part 12 are fixed together and can be rotated (for example, to achieve the following water path switching by rotation) or detachably connected as needed. The water outlet part 12 is provided with a first water outlet nozzle 121. The movable part 2 is movable and installed in the main body part 1 and can move between a first position and a second position relative to the main body part 1.

The descaling parts 22 of the movable part 2 located in the first position are inserted into the first water outlet nozzle 121 to be in a pressurized descaling state. On the one hand, descaling and impurity removal are achieved by insertion. On the other hand, after insertion, the water flow area of ​​the first water outlet nozzle is reduced to achieve pressurization, enhance the water splash intensity, and increase the spray distance. Furthermore, the first water outlet is arranged with a water flow area gradually decreasing toward the water outlet and the end of the descaling component of the movable part 2 in the first position extends out of the water outlet to enhance the pressurized descaling effect, and the descaling component 22 of the movable part 2 in the second position is pulled out of the first water outlet or only the end of the descaling component 22 is located at the water inlet position of the first water outlet to be in a normal water outlet state; the elastic body 4 is pressed between the water outlet component 12 and the movable plate 21 of the movable part 2 and when it moves from the second position to the first position, the elastic body 4 stores energy and can generate elastic force acting on the movable part 2. The waterway switching component 3 is provided on the main body 11 of the main body 1 and includes a water inlet 31, at least two waterways 321, 322, 323 and a switching mechanism 33 provided between the water inlet and the waterway. The waterway can be switched to connect the water inlet 31 by the switching mechanism 33. The switching mechanism 33 can adopt an existing switching mechanism, such as rotating switching, sliding switching, swinging switching, etc. The at least two waterways 32 include a first waterway 321 and a second waterway 322. The first waterway 321 and the second waterway 323 are connected to each other. When the paths 322 are both connected to the first water outlet 121 to switch to the first and second water outlets, the first water outlet both discharges water to achieve different water splashes from one water outlet. The water flowing through the first water outlet 321 acts on the movable part 2 with a first force that drives the movable part 2 to move to the first position. The water flowing through the second water outlet 322 acts on the movable part 2 with a second force and an elastic force that drives the movable part 2 to move to the second position.
