Description

Technical Field

[0001] The utility model relates to the field of water-saving shower heads, in particular to a cleaning mechanism for water-saving shower heads. Background Art

[0002] Shower heads, also known as shower heads, were originally devices for watering flowers, potted plants and other plants. Later, some people modified them into shower devices, making them common items in bathrooms. Water-saving shower heads enter the nozzle base of the shower head through water flow, and the water flow passing through the three-wing accelerator forms a relative selection effect, thereby increasing the speed and impact of the water flow, thereby achieving the effect of saving water. However, water-saving shower heads have the following shortcomings: after the water-saving shower head is stopped, a certain amount of water flow will accumulate inside the nozzle base. The water flow stays inside the nozzle base for a long time, which is easy to produce scale inside the nozzle base, thereby causing blockage inside the nozzle base. After blockage, the nozzle base needs to be disassembled for cleaning, which is inconvenient during the cleaning process. Utility Model Content

[0003] In view of the above problems, the utility model provides a cleaning mechanism for a water-saving showerhead.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a cleaning mechanism for a water-saving shower head, whose structure includes a threaded joint pipe, a hand-held rod pipe, and a nozzle mechanism. The threaded joint pipe is fixedly installed at the bottom of the hand-held rod pipe and is through-connected, and the nozzle mechanism is installed on the top of the hand-held rod pipe and is through-connected.

[0005] As a further improvement of the utility model, the nozzle mechanism includes a nozzle base, a water outlet panel, a central water outlet hole, a middle ring water outlet hole, an outer ring water outlet hole, and an adjustment plate. The nozzle base is installed on the top of the handheld rod tube and is through-connected. The nozzle base is embedded in the back of the water outlet panel. The central end of the water outlet panel is embedded with a central water outlet hole, and a middle ring water outlet hole is provided on the outside of the central water outlet. An outer ring water outlet hole is embedded on the outside of the middle ring water outlet hole. The adjustment plate is installed at the lower end of the water outlet panel, and the adjustment plate is mechanically connected to the central water outlet hole, the middle ring water outlet hole and the outer ring water outlet hole.

[0006] As a further improvement of the utility model, the nozzle base includes a base shell, a cleaning mechanism, a filter hole, an elastic strip, and a protrusion. The base shell is installed on the top of the handheld rod tube and is through-connected. The base shell is embedded in the back of the water outlet panel. The cleaning mechanism is embedded in the base shell and is through-connected. The front surface of the cleaning mechanism is embedded with a filter hole, and the inside of the filter hole is connected to the protrusion through an elastic strip.

[0007] As a further improvement of the utility model, the cleaning mechanism includes an outer shell, filter particles, a positioning shaft, and blades. The outer shell is embedded in the base shell and is through-connected. The front surface of the outer shell is embedded with filter holes. The filter particles are installed inside the outer shell. A positioning shaft is installed at the middle end of the inner part of the outer shell with a clearance fit. Blades are installed on the outer side of the positioning shaft, and the blades are located inside the outer shell.

[0008] As a further improvement of the utility model, there are multiple filter holes, which are distributed in a ring array on the front surface of the cleaning mechanism, and each filter hole has four positions inside it and an elastic strip connected to the four positions outside the protrusion.

[0009] As a further improvement of the present invention, the filter particles are made of calcium sulfite, which has the advantages of good hardness, high efficiency and short reaction time.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the utility model, water flows through the handheld rod tube into the interior of the outer shell on the inner side of the base shell, and the water flows are filtered by the filtering particles inside the outer shell. While filtering, the blades are rotated around the positioning axis by the impact of the water flow, which can drive the water flow and increase the impact force of the water flowing out from the filter hole.

[0012] According to the utility model, when water flows out from the filter hole, the elastic traction of the elastic strip enables the projection to clear the center water outlet hole, the middle ring water outlet hole and the outer ring water outlet hole, preventing the center water outlet hole, the middle ring water outlet hole and the outer ring water outlet hole from being blocked by scale, thereby achieving a self-cleaning effect.
