Description

Technical Field

[0001] The invention relates to an automatic descaling shower head. Background Art

[0002] There are many areas in China with poor water quality and relatively hard water, which makes it easy for scale to form. These scales can easily block the water spouts of the water outlets, resulting in small water flows or bifurcations, thus affecting the water experience, especially the shower experience, making the overall water splash effect poor and the integrity poor. Existing descaling shower heads require manual pushing to remove the scale from the water spouts, which is very time-consuming and labor-intensive. The top plate can also be reset by elastic parts, but this structure is complicated and requires setting the installation position of the elastic parts.

[0031] Referring to the drawings of the specification, an automatic descaling shower head includes a body 10 with a water outlet 11, which can eventually form a water outlet device such as a shower head or a shower head. A movable plate 20 is arranged in the body, and a thimble 21 that can be inserted into the water outlet is arranged on the movable plate. In use, the body has multiple water outlet functions, so that the body has multiple groups of water outlet holes. The water outlet holes that need to be descaled in the present invention are water splashes with relatively low water outlet pressure, such as shower water. When the shower water does not discharge water, when other water splashes discharge water, the thimble is inserted into the water outlet hole for descaling work, and when the shower water discharges water, the thimble moves up to ensure that the water outlet hole can discharge water normally. Water; also includes a first water inlet 31, the water flow of the first water inlet can flow to the bottom of the movable plate and lift the movable plate, mainly through the reverse impact and / or buoyancy of the water, so that the ejector pin can move up from the water outlet, and the water flows out from the water outlet; also includes a second water inlet 32, the water flow of the second water inlet can flow to the top of the movable plate and press the movable plate downward, mainly through the pressure of the water, so that the ejector pin can be inserted into the water outlet to push the scale out of the water outlet. The device omits the elastic part (spring) in the prior art, reduces the use of parts, and at the same time, there is no need to consider the problem of opening the mold at the installation position of the elastic part in production, thereby simplifying the structure.

[0032] Preferably, the main body includes a panel 12, the water outlet is arranged on the panel, a water baffle 30 is also arranged in the main body, the movable plate can move between the water baffle and the panel, and a water diversion plate 40 is also arranged in the main body, the water diversion plate is located above the water baffle, and the water diversion plate can enable the main body to form multiple water channels (or water diversion chambers), each water channel can form a kind of water splash, and the formation of water channels is similar to the prior art and will not be elaborated here.

[0033] Furthermore, a first water-dividing chamber 13 can be formed between the water-dividing plate and the water-blocking plate, and the water flow flowing into the first water-dividing chamber can flow to the bottom of the movable plate; a first guide column 33 is provided on the water-blocking plate, a first water inlet is formed in the first guide column, and the first water-dividing chamber can be connected with the first water inlet; a first guide hole 22 is provided on the movable plate, and the first guide column is inserted into the first guide hole. A connecting ring 14 is provided on the panel, and the connecting ring can be located at the periphery of the first guide column, and the top surface of the connecting ring is not lower than the bottom surface of the first guide column. In use, the top surface of the connecting ring is higher than the bottom surface of the first guide column, so that the water flow can form multiple bends (flowing from the first water inlet, then turning upward when reaching the panel, and then turning downward again after hitting the lower end surface of the movable plate and flowing out from the water outlet), and a first water outlet chamber 15 can be formed between the panel and the movable plate, and the first water outlet chamber can be connected with the first water inlet and the water outlet.

[0034] Furthermore, an upwardly recessed trough 23 is provided on the lower end surface of the movable plate, and the trough can be located on the outer periphery of the connecting ring, that is, there is a water passage between the outer periphery of the connecting ring and the inner peripheral wall of the trough, so that the water flow of the first water diversion chamber can pass through the connecting ring and then flow downward from the water outlet, and the water flow flowing into the first water inlet can flow into the connecting ring and then flow upward to the bottom of the trough, and then flow downward into the first water outlet chamber and then flow out of the water outlet, forming multiple deflections of the water flow.

[0035] Preferably, a second water diversion chamber 16 can be formed between the water diversion plate and the water baffle plate, and the water flowing into the second water diversion chamber can flow to the top of the movable plate. A second water inlet is provided on the water baffle plate, and a second guide column 24 is provided on the movable plate. The second guide column can be plugged into the second water inlet, and the water flow in the second water diversion chamber can act on the second guide column through its water pressure, forcing the movable plate to move downward, and the ejector pin is inserted into the water outlet to perform descaling.

[0036] Furthermore, the outer peripheral wall of the second guide column is provided with a sealing ring 25 that can be sealed with the second water inlet, and the water in the second water distribution chamber can act on the second guide column to move the movable plate downward. The second guide column is provided with a groove that is sunken downward, and the water flow of the second water distribution chamber can act on the groove through the second water inlet. In a preferred embodiment of the present invention, a second water outlet chamber can also be formed in the body, and the second water outlet chamber is connected to the second water inlet. The water flow of the second water outlet chamber can flow out from other water outlet holes on the panel (for example, the water outlet hole for granular water). The second guide column only needs to divert the water pressure from part of the second water outlet chamber to realize the downward movement of the movable plate. Of course, it is also possible to directly pause the water (stop the water or slightly pass the water) without discharging the water.

[0037] Furthermore, a water inlet chamber 17 is also provided in the main body, and a rotatable water dividing plate 50 is provided in the water inlet chamber, and a sealing member 51 is provided between the water dividing plate and the water dividing plate. In normal use, a water dividing port is provided on the water dividing plate, and a water inlet which can be connected with the water dividing port is correspondingly provided on the water dividing plate. Each water inlet corresponds to a water dividing chamber, so that the water flow can be switched by the rotation of the water dividing plate. This technology is similar to the existing technology and will not be elaborated in detail here. The switching of the water flow can realize whether to perform descaling.

[0038] Preferably, a water inlet 60 is also provided in the body, and the water inlet can be connected with the water inlet chamber; a push button 71 is also provided on the body, and the push button can move synchronously with a push rod 72 provided in the body, and the push rod is provided with a rack 73 and also includes a gear 74, and the gear can mesh with the rack, and the gear is provided with a rotating shaft 75 that can rotate synchronously, one end of the rotating shaft is located in the water inlet chamber and connected to the water dividing plate, and the rotation of the rotating shaft is driven by pushing the push button, thereby realizing the switching of water flow, that is, switching whether to perform descaling operation.

[0039] More specifically, the present invention is as follows: the water path enters the water inlet chamber inside the body (which can be a shower or a shower head) through the water inlet channel 60. It passes through the water dividing plate, passes through different water dividing chambers, and then flows out from different water outlet holes on the panel. By pushing the push button to rotate the water dividing plate, the water flows into different water dividing chambers for water discharge. By switching the first and second water dividing chambers, the position of the movable plate is adjusted. When the first water dividing chamber is flowing, the water flows from the bottom to the top into the first water outlet chamber, and the water pressure does not release pressure, so the movable plate can only be lifted to form water discharge. At this time, the movable plate and the ejector are away from the water outlet hole, and water (which can be shower water) flows out of the water outlet hole. After the push button is pushed, the water path is switched to the second water dividing chamber for water flow, and the water pressure acts on the second guide column formed by the inner ring movable plate of the second water inlet to form a seal. At this time, under the action of the sealing ring, the movable plate is moved downward by the water pressure, and the ejector is inserted into the water outlet hole (at this time, other non-shower water can be switched to discharge water). If there is dirt in the water outlet hole, it will be supported by the ejector together to achieve one-time descaling. When the water is switched to the first water chamber again, the second water chamber of the movable plate has no water pressure, so the first water chamber is turned to provide water pressure; the water channel switching process relies on the water pressure of different water channels to repeat the process of the pin retracting and pushing out. Preferably, except for the second water chamber acting on the second guide column, the rest of the water channels can flow into the bottom of the movable plate, and the specific structure is similar to the first water outlet chamber. When the first water outlet is discharged, the movable plate is impacted by the water pressure. At this time, the movable plate retracts, and the first water outlet is discharged normally.
