Description

Technical Field

[0001] The utility model belongs to the technical field of bathing equipment, and in particular relates to a household water-saving shower head. Background Art

[0002] The size of the spray hole of the existing shower head is fixed and cannot be changed during use. During the water spraying process, when it is necessary to increase the water flow, the water pressure of the tap water must be increased, resulting in a waste of tap water, which is not conducive to the water-saving use of the shower head. Among them, the "an efficient and durable water-saving shower head" disclosed in the application number "CN201820225696.1" is also an increasingly mature technology. The worm gear mechanism is used to drive the transmission gear to rotate by adjusting the nut, and the transmission gear then drives the water retaining disc to rotate. When the water retaining disc rotates to the appropriate position, the worm gear is used to The self-locking performance of the mechanism can ensure the stability of the relative position between the water retaining hole and the water spray hole on the water retaining disc, and flexibly adjust the size of the actual water outlet hole. However, the device also has the following defects: in actual use, there is residual water in the existing shower head after use. During the placement of the shower head, although the water supply end is closed, the residual water flow leaks from the shower head, causing water waste. The water outlet end of the shower head cannot be automatically closed after use, resulting in water leakage. When the shower head is damaged, there is water flow in the shower head due to poor sealing. Utility Model Content

[0003] The purpose of the utility model is to provide a household water-saving shower head, aiming to solve the problem in the prior art that water remains in the shower head after use, and when the shower head is placed, although the water supply end is closed, the residual water flow leaks from the shower head, causing water waste, and the shower head cannot automatically close the water outlet end after use.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: it includes a connecting seat, a control tube is provided at one end of the connecting seat, a shower head is connected to the top of the control tube, a funnel-shaped cavity is provided at the top of the inner wall of the shower head, a first water outlet plate is provided on one side of the inner wall of the funnel-shaped cavity, a water mist adjustment plate is rotatably connected to the side of the first water outlet plate, a through pipe is provided on the inner wall of the shower head, the top of the through pipe is sealed and connected to the funnel-shaped cavity, a guide groove is provided in the middle of the inner wall of the funnel-shaped cavity, a top plate is movably connected in the guide groove, a plurality of water outlet pipes are provided on the front of the surface of the first water outlet plate, and sockets corresponding to the water outlet pipes are provided on the surface of the top plate, and the water outlet pipes are inserted and connected in the sockets.

[0005] In an embodiment of a household water-saving sprinkler head of the present utility model, a through hole is provided at the bottom of one end of the water outlet pipe, and a first PVE spring is provided between the guide groove and the top plate.

[0006] In this solution, when water flows into the funnel-shaped cavity, the water flows into the top plate and squeezes the first PVE spring. At this time, the outlet pipe protrudes from the socket, the through hole opens and is exposed to the outside, and the water flows out through the outlet pipe. When the water flow decreases, the first PVE spring resets, the top plate rebounds, and the through hole retracts into the socket, automatically blocking the water outlet to avoid water waste.

[0007] In an implementation scheme of a household water-saving sprinkler head of the utility model, an adjustment cavity is opened on the inner wall of the control tube, a limit column is provided on the top of the inner wall of the adjustment cavity, a second PVE spring is provided on the outer wall of the limit column, and a blocking block is provided at one end of the second PVE spring, and the blocking block is movably connected to the limit column.

[0008] In this solution, when water flows into the control pipe, the water impacts the trapezoidal sealing plug, and the second PVE spring is squeezed, retracting the sealing block into the limit column, reducing the impact force of the water flow and the amount of water outflow. When the water source is turned off, the second PVE spring rebounds, blocking the water inlet with the trapezoidal sealing plug to prevent water overflow.

[0009] In an embodiment of a household water-saving sprinkler head of the present utility model, water outlet holes are provided on both sides of the top of the inner wall of the regulating cavity, and a water inlet hole is provided on the bottom of the inner wall of the regulating cavity.

[0010] In this solution, water flows in from the water inlet and out from the water outlet, and then the water source flows into the through pipe for water supply.

[0011] In an embodiment of the household water-saving sprinkler head of the utility model, a sealing gasket is provided on the inner wall of the insertion hole.

[0012] In this solution, when the through hole is retracted into the insertion hole, the sealing gasket prevents water from leaking into the insertion hole, thereby improving the sealing performance, avoiding water waste, and saving water resources.

[0013] In an implementation scheme of a household water-saving sprinkler head of the utility model, a trapezoidal sealing plug is provided at the bottom of the blocking block.

[0014] In this solution, the water inlet hole is blocked by a trapezoidal sealing plug to improve the sealing performance of the water inlet hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1) The water flow impacts the top plate, squeezing the first PVE spring. At this time, the outlet pipe protrudes from the socket, the through hole is opened and exposed to the outside, and the water flows out through the outlet pipe. When the water flow decreases, the first PVE spring resets and the top plate rebounds. When the through hole retracts into the socket, the sealing gasket prevents water from leaking into the socket and automatically blocks the water outlet, thereby improving the sealing performance, avoiding water waste, saving water resources, and avoiding water waste;

[0017] 2) When the water flow impacts the trapezoidal sealing plug, the second PVE spring is squeezed, and the sealing block is retracted into the limit column, reducing the impact force of the water flow and the amount of water outflow. When the water source is turned off, the second PVE spring rebounds, blocking the water inlet with the trapezoidal sealing plug, preventing water from overflowing and preventing excess water from flowing into the shower head and causing water overflow after damage, thereby further reducing waste.
