Description

Technical Field

[0001] This utility model relates to an automatic descaling device. Background Technology

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] Referring to the accompanying drawings, an automatic descaling device includes a body 10 with water outlets 11, which ultimately forms a water outlet device such as a shower head or shower faucet. A movable plate 20 is provided within the body, and a pin 21 that can be inserted into the water outlet is provided on the movable plate. In use, the body has multiple water outlet functions, thus having multiple sets of water outlets. In this invention, the water outlet requiring descaling is a low-pressure water jet, such as shower water. When the shower water is not flowing, but other water jets are flowing, the pin is inserted into the water outlet to perform descaling. When the shower water is flowing, the pin moves upward to ensure the water outlet can function normally. The device includes a first water inlet 31, through which water flows to the bottom of the moving plate and lifts the moving plate. The ejector pin moves upward from the water outlet mainly through the reverse impact and / or buoyancy of the water, and the water flows out from the water outlet. It also includes a second water inlet 32, through which water flows to the top of the moving plate and presses the moving plate down. The ejector pin inserts into the water outlet mainly through the water pressure and pushes out the scale from the water outlet. This device eliminates the elastic element (spring) in the prior art, reduces the number of parts used, and also eliminates the need to consider the mold opening problem of the installation position of the elastic element in production, thus simplifying the structure.

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

[0033] Furthermore, a first water-dividing cavity 13 can be formed between the water-dividing plate and the water-separating plate, and the water flowing into the first water-dividing cavity can flow to the bottom of the moving plate; a first guide post 33 is provided on the water-separating plate, and a first water inlet is formed in the first guide post. The first water-dividing cavity can be connected to the first water inlet. A first guide hole 22 is provided on the moving plate, and the first guide post is inserted into the first guide hole. A connecting ring 14 is provided on the panel. The connecting ring can be located on the outer periphery of the first guide post. The top surface of the connecting ring is not lower than the bottom surface of the first guide post. In use, the top surface of the connecting ring is higher than the bottom surface of the first guide post, so that the water flow can form multiple bends (water enters from the first water inlet downwards, then bends upwards when it reaches the panel, and then bends downwards again after hitting the lower end surface of the moving plate and flows out from the water outlet). A first water outlet cavity 15 can be formed between the panel and the moving plate, and the first water outlet cavity can be connected to the first water inlet and the water outlet.

[0034] Furthermore, the lower end face of the movable plate is provided with an upwardly recessed sink 23. The sink 23 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 sink 23. This allows the water flow in the first water distribution chamber to flow downward from the outlet hole after passing through the connecting ring. The water flow in the first inlet can flow into the connecting ring and then flow upward to the bottom of the sink 23, and then flow downward into the first outlet chamber and out of the outlet hole, forming multiple bends in the water flow.

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

[0036] Furthermore, the outer peripheral wall of the second guide post is provided with a sealing ring 25 that can seal with the second water inlet. The water in the second water distribution chamber can act on the second guide post, causing the moving plate to move downward. The second guide post is provided with a downwardly recessed groove, and the water flow in the second water distribution chamber can act on the groove through the second water inlet. In a preferred embodiment of this utility model, a second water outlet chamber can also be formed in the main body. The second water outlet chamber is connected to the second water inlet, and the water flow in the second water outlet chamber can flow out from other water outlets on the panel (such as water outlets for particulate water). The moving plate can move downward by diverting the water pressure from part of the second water outlet chamber on the second guide post. Of course, it is also possible to stop the water flow (stop the water or allow a small amount of water to pass through) without water discharge.

[0037] Furthermore, the main body is also provided with a water inlet chamber 17, and a rotatable water distribution plate 50 is provided in the water inlet chamber. A sealing element 51 is provided between the water distribution plate and the water distribution plate. In normal use, the water distribution plate is provided with a water outlet, and the water distribution plate is provided with a corresponding water inlet that can be connected to the water outlet. Each water inlet corresponds to a water distribution chamber. In this way, the water flow can be switched by rotating the water distribution plate. There are existing similar technologies, which will not be described in detail here. The switching of water flow can determine whether to perform descaling.

[0038] Preferably, the main body is further provided with a water inlet channel 60, which can communicate with the water inlet chamber; the main body is also provided with a push button 71, which can move synchronously with a push rod 72 provided in the main body. The push rod is provided with a rack 73 and a gear 74, which can mesh with the rack. 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 divider. By pushing the push button, the rotating shaft is driven to rotate, thereby realizing the switching of water flow, that is, switching whether to perform descaling operation.

[0039] More specifically, this utility model describes a water system where water enters the main body (which can be a shower head or suds head) through the inlet channel 60 into the inlet chamber. After passing through a water divider, the water flows through different water dividers and then out through different outlet holes on the panel. By pushing the push button to rotate the water divider, water is switched to different water dividers for output. Switching between the first and second water dividers adjusts the position of the moving plate. When water flows through the first water divider, the water flows upwards into the first outlet chamber. Without pressure relief, the moving plate is lifted to form the outlet, at which point the moving plate and the ejector pin move away from the outlet hole, and water (shower water) flows out. Pushing the push button switches the water system to the second water divider. The water pressure acts on the second guide post, forming a seal on the inner ring of the moving plate of the second inlet. Under the action of the sealing ring, the moving plate moves downwards under water pressure, and the ejector pin inserts into the outlet hole (at which point other non-shower water can be switched out). If there is dirt in the outlet hole, it will be blocked by the ejector pin, achieving descaling in one operation. When the flow path switches back to the first water passage chamber, there is no water pressure in the second water distribution chamber of the moving plate, so the flow path switches to the first water distribution chamber to provide water pressure. The water path switching process relies on the water pressure of different water paths to repeatedly retract and push the ejector pin. Preferably, except for the second water distribution chamber which acts on the second guide post, the other water paths can all enter the lower part of the moving plate, with a specific structure similar to the first water outlet chamber. When the first water outlet is opened, the moving plate is impacted by water pressure. At this time, the moving plate retracts, and the first water outlet opens normally.

As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge.
