Description

Technical Field

[0001] The present invention relates to a self-cleaning shower head. Background Art

[0002] In many regions in China, the water quality is poor. After a long time, scale is likely to appear in the water outlet holes of shower heads or shower heads, which will block the water outlet holes, resulting in no water outlet or inconsistent and uncoordinated water outlet directions, thus greatly affecting the user's shower experience. Existing descaling shower heads or shower heads all require manual pushing to eject the internal ejector pin. Although descaling can be achieved, the position of the shower head is relatively high and the hand can't reach it. A ladder or a chair is needed to perform the descaling operation, which is quite inconvenient. Moreover, in places with severe humidity in the bathroom, standing on a high place also poses a risk of falling and causing injury to the user. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a self-cleaning shower head.

[0004] The present invention is realized through the following technical solutions:

[0005] A self-cleaning shower head includes a body having a water inlet cavity, a water outlet cavity and water outlet holes. The water outlet cavity can communicate with the water outlet holes. A thimble plate is arranged in the water outlet cavity, and thimbles that can be inserted into the water outlet holes are arranged on the thimble plate; a water passing cavity is located between the water inlet cavity and the water outlet cavity. An outlet is arranged between the water passing cavity and the water outlet cavity. A lifting rod that can cooperate with the thimble plate is arranged in the water passing cavity. First and second connecting plates are arranged up and down on the lifting rod. The second connecting plate can be connected with the outlet in a matching manner; the acting area S1 of the water flow in the water passing cavity on the first connecting plate is larger than the acting area S2 of the water flow in the water passing cavity on the second connecting plate, so that the water flow can lift the lifting rod to drive the thimble plate to move.

[0006] In an embodiment of the present invention, a water inlet is arranged between the water inlet cavity and the water passing cavity. A sealing ring is arranged between the outer periphery of the first connecting plate and the inner peripheral wall of the water passing cavity, and the sealing ring is located outside the water inlet.

[0007] In an embodiment of the present invention, a connecting hole is arranged on the thimble plate. The lower end of the lifting rod can be inserted into the connecting hole, and an abutting block that can cooperate with the thimble plate is further arranged on the outer periphery of the lower end of the lifting rod, so that the lifting rod can drive the thimble plate to move upward.

[0008] In an embodiment of the present invention, a slot is further arranged at the lower end of the lifting rod. An abutting block is arranged on the outer periphery of the lifting rod on both sides of the slot. The abutting block can abut against the bottom surface of the thimble plate beside the connecting hole. A guiding inclined surface is arranged on the outer periphery of the lower end of the abutting block to facilitate the insertion of the lower end of the lifting rod into the connecting hole from top to bottom.

[0009] In an embodiment of the present invention, a water passage is formed between the lifting rod located below the second connecting plate and the water outlet. After the second connecting plate moves away from the water outlet, the water flow in the water passage chamber can flow through the water passage to the water outlet chamber.

[0010] In an embodiment of the present invention, the ejector plate is also connected with a return spring in cooperation; when there is no water flow in the water passage chamber, the return spring can drive the ejector plate to move downward, and the ejector pin is inserted into the water outlet hole.

[0011] In an embodiment of the present invention, a guide post is arranged on the upper end surface of the ejector plate, a guide hole adapted to the guide post is arranged in the body, and a return spring located in the water outlet chamber is sleeved on the outer periphery of the guide post.

[0012] In an embodiment of the present invention, water passing notches are arranged on the ejector plate, and the water flow in the water outlet can flow through the water passing notches to the water outlet hole.

[0013] In an embodiment of the present invention, the ejector plate and the lifting rod are integrally provided or separately provided.

[0014] A self-cleaning shower head of the present invention has the following beneficial effects: 1. The ejector plate is reversely pushed through the water pressure difference, making the structure more stable; through its own weight and the superimposed return spring, the ejector pin of the ejector plate can be better inserted into the water outlet hole for descaling operation; 2. The ejector plate and the lifting rod are more convenient to install through the clamping limit mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0026] In the present invention, unless otherwise clearly defined and limited, the terms "mounted", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween.

The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0028] Referring to the accompanying drawings of the specification, a self-cleaning shower head includes a body 10 having a water inlet chamber 11, a water outlet chamber 12 and water outlet holes 13. The water outlet holes are arranged on a water outlet panel below the body. The water outlet chamber can communicate with the water outlet holes so that the water flow in the water outlet chamber can smoothly flow to the water outlet holes. A thimble plate 20 is arranged in the water outlet chamber, and thimbles 21 that can be inserted into the water outlet holes are arranged on the thimble plate. When the water is turned off, the thimbles are inserted into the water outlet holes for descaling work. When the water is turned on, the thimbles move upward and away from the water outlet holes so that the water outlet holes can discharge water smoothly; a water passing chamber 30 is located between the water inlet chamber and the water outlet chamber. An outlet 31 is arranged between the water passing chamber and the water outlet chamber. A lifting rod 40 that can cooperate with the thimble plate is arranged in the water passing chamber. First connecting plates 41 and second connecting plates 42 are arranged up and down on the lifting rod. The second connecting plate can be cooperatively connected with the outlet. In one embodiment, the cross-sections of the first connecting plate and the second connecting plate are circular, and the second connecting plate can be adapted to the shape of the outlet for blocking the outlet; the acting area S1 of the water flow in the water passing chamber on the first connecting plate is larger than the acting area S2 of the water flow in the water passing chamber on the second connecting plate. These two acting areas will form a difference, which can also be the difference in the cross-sectional areas of the two connecting plates. Mainly, the water flow acts on them so that the water flow can lift the lifting rod to drive the thimble plate to move.

[0029] Preferably, a water inlet 32 is arranged between the water inlet chamber and the water passing chamber. A sealing ring 43 is arranged between the outer periphery of the first connecting plate and the inner peripheral wall of the water passing chamber. The sealing ring is located outside the water inlet. Referring to the embodiment of the accompanying drawings Figure 4 In the embodiment, the sealing ring is located above the water inlet. In this way, water leakage in the water passing chamber can be avoided, and at the same time, the loss of water pressure can be prevented. In this way, the water flow can only flow to the outlet. The sealing ring can ensure the acting force of the water flow on the two connecting plates and ensure that there is no water leakage phenomenon.

[0030] Further, the ejector plate is provided with a connection hole 22, into which the lower end of the lifting rod can be inserted, and an abutment block 44 which can cooperate with the ejector plate is also provided on the outer periphery of the lower end of the lifting rod, so that the lifting rod can drive the ejector plate to move upward. The lower end of the lifting rod is also provided with a slot 45, and an abutment block is provided on the outer periphery of the lifting rod located on both sides of the slot, and the abutment block can abut against the bottom surface of the ejector plate beside the connection hole. A guide slope 46 is provided on the outer periphery of the lower end of the abutment block, so that the lower end of the lifting rod can be inserted into the connection hole from top to bottom. When the lifting rod is inserted into the connection hole from top to bottom, the side wall of the connection hole acts on the guide slope to compress the two sides of the slot, and the slot size is reduced until the abutment block is located below the connection hole, and the two sides of the slot rebound, so that the abutment block is carried on the lower end surface of the ejector plate beside the connection hole, so that when the lifting rod moves upward, the ejector plate also moves upward. A water passage 33 is formed between the lifting rod and the water outlet below the second connecting plate. After the second connecting plate moves away from the water outlet, the water in the water passage cavity can flow to the water outlet cavity through the water passage.

[0031] Furthermore, the ejector plate is also connected with a reset spring 23; when there is no water flow in the water cavity, the reset spring can drive the ejector plate to move downward, and the ejector is inserted into the water outlet. At the same time, the gravity is superimposed, so that the ejector can be quickly inserted into the water outlet, which can make the descaling work better. The upper surface of the ejector plate is provided with a guide column 24, and the body is provided with a guide hole 14 that can adapt to the guide column. The outer periphery of the guide column is sleeved with a reset spring located in the water outlet cavity.

[0032] In one embodiment, the ejector plate is provided with a water-passing notch 25, and the water in the water outlet can flow to the water outlet hole through the water-passing notch. The ejector plate and the lifting rod are integrally or separately arranged.

[0033] In the use of the present invention, the lifting rod and the ejector plate can be integrated or divided into two parts, which can be reasonably rotated according to the application scenario. In order to facilitate production, the lifting rod and the ejector plate can be disassembled and designed. At the same time, if the product (such as top spray) is large in size and the precision error of the integrated one is not convenient for production, the lifting rod and the ejector plate can also be disassembled and designed. If the product size is small, the lifting rod and the ejector plate can be combined into one piece during production.

[0034] More specifically, in the anhydrous state, that is, when there is no water supply, the reset spring drives the lifting rod to move downward when moving the thimble plate downward. When the thimble moves downward to the water outlet hole, if the water outlet hole is blocked by dirt, the thimble will push out the dirt to achieve the function of removing dirt; when in the water outlet state, water enters the water inlet cavity from the ball head and then flows to the water passage cavity. Since the areas of the upper and lower connecting plates of the lifting rod are different, and the water pressure at the bottom water outlet cannot be relieved, an upper and lower pressure difference is formed. The water pressure pushes the lifting rod upward to achieve water outlet at the water outlet, and at the same time, the thimble is also moved away from the water outlet hole. After the pressures of the two are balanced, the lifting rod will stop rising, and the water flows from the water passage into the water outlet cavity and then out through the water outlet hole. Due to the limiting mechanism formed by the contact between the lifting rod and the thimble plate, when the lifting rod rises, it drives the thimble plate to rise, and the reset spring is compressed; after turning off the water, the reset spring pushes the thimble plate downward, and the start and the anhydrous state achieve cyclic operation through turning on and off the water.
