Description

Technical Field

[0001] This utility model relates to the field of water spout technology, specifically to a water spout for a faucet. Background Technology

[0002] A faucet spout, commonly known as an aerator, is a small device installed at the spout of a faucet. Its function is to increase the amount of air bubbles in the water flow, making the water flow gentler and saving water. The principle of a faucet aerator is to use air bubbles generated by the entry of air into the water flow to reduce the water flow intensity. Air bubbles are generated at the very small aperture of the aerator spout. When water flows out of this small aperture, the air bubbles enter the water along with it, thus reducing the mass of the water flow, softening the flow, and reducing the water volume.

[0003] Although traditional aerators can be installed and removed from the faucet outlet via their threaded surfaces, when the aerator's outlet becomes clogged and needs cleaning, it is necessary to first reverse the aerator to remove it from the faucet outlet, and then reverse the aerator back onto the faucet outlet after cleaning. This cleaning process requires frequent twisting, making it cumbersome and difficult to reduce the time spent cleaning the aerator. Utility Model Content

[0004] The purpose of this utility model is to provide a water spout for a faucet, addressing the defects and shortcomings of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a faucet spout, comprising a spout housing for connecting to the spout end of an external faucet, a spout perforation formed through the spout housing, a spout block disposed on the spout housing within the spout perforation for rising or falling within the spout perforation when driven by an external force, a limiting member disposed on the spout housing within the spout perforation and above the spout block for restricting the rise of the spout block when it rises to a predetermined position within the spout perforation, and a limiting member disposed between the limiting member and the spout block. The system includes: an adsorption device for adsorbing and fixing the water outlet block to the limiting member when the water outlet block is restricted from rising; a sealing member disposed between the water outlet block and the water outlet housing for sealing the gap between the water outlet block and the water outlet housing after the adsorption device adsorbs and fixes the water outlet block to the limiting member; several water outlet holes opened on the water outlet block for supplying water flow from the water outlet block; a water outlet channel opened on the limiting member for supplying water flow into the water outlet holes; and a driving member disposed on the water outlet block for allowing a hand to remove the water outlet block from the water outlet perforation.

[0006] A further improvement is that the adsorption device includes at least one first adsorption block fixedly disposed on the limiting member, and a second adsorption block fixedly disposed on the upper end face of the water outlet block and magnetically adsorbed with the first adsorption block.

[0007] A further improvement is that the adsorption device includes a first adsorption block disposed on the water outlet housing and located on the periphery of the water outlet block, and a second adsorption block disposed on the periphery of the water outlet block and magnetically adsorbed with the first adsorption block, wherein the first adsorption block is located below the limiting member.

[0008] A further improvement is that both the first and second adsorption blocks are magnetic blocks, and the magnetic poles of the first and second adsorption blocks are opposite.

[0009] A further improvement is that the first adsorption block is a magnetic block, and the second adsorption block is a metal block that can be adsorbed by the magnetic block.

[0010] A further improvement is that the second adsorption block is a magnetic block, and the first adsorption block is a metal block that can be adsorbed by the magnetic block.

[0011] A further improvement is that the sealing element includes an installation groove formed on the water outlet housing and communicating with the water outlet perforation, and a sealing ring disposed on the water outlet housing within the installation groove, the installation groove being located on the periphery of the water outlet block.

[0012] A further improvement is that the sealing element includes an installation groove formed on the periphery of the water outlet block and a sealing ring disposed on the water outlet block within the installation groove.

[0013] A further improvement is that the driving component includes a driving column for two fingers to grip on the lower end face of the water outlet block, and an anti-slip ball on the lower end face of the driving column, with the driving column vertically positioned at the lower center of the water outlet block.

[0014] A further improvement is that several engaging grooves are provided on the lower periphery of the water outlet shell.

[0015] A further improvement is that an auxiliary ring groove is formed on the upper end face of the water outlet shell, and an auxiliary sealing ring is provided on the upper end face of the water outlet shell within the auxiliary ring groove.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the water outlet of the aerator is blocked and needs to be cleaned, the water block is removed from the water outlet perforation by the drive component, so that the adsorption device releases the fixation of the water block and the limiting component, thereby clearing the blockage of the water block. Then, simply place the upper end of the water block into the water outlet perforation with the direction of the limiting component aligned with the limiting component, and push the water block upward so that it abuts against the lower end of the limiting component. The lower end of the limiting component restricts the rise of the water block, and the adsorption device adsorbs and fixes the water block and the limiting component. The gap between the water block and the water outlet housing is sealed by the sealing component. When the water flows from the water outlet of the faucet into the water outlet perforation, the water flows outward through the water outlet channel and the water outlet. Compared with the cleaning process of traditional aerators, there is no need to frequently twist, the operation is simpler, and the cleaning process of the aerator can be reduced.

[0017] Further benefits: The channel formed on the limiting component not only allows for the installation of the first adsorption block and the passage of water flow, but also disperses the water flow in the form of a water column before it enters the water outlet perforation body and the water outlet block, so that the dispersed water flow enters the water outlet hole, thereby making the water outlet effect of the water outlet block uniform.

[0018] Further benefits: When the upper end of the water outlet housing is connected to the water outlet end of the faucet, the gap between the upper end of the water outlet housing and the water outlet end of the faucet can be sealed by the auxiliary sealing ring, thereby reducing the occurrence of leakage after the water outlet is installed.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0030] See Figures 1 to 8 As shown, the technical solution adopted in this specific embodiment is: a faucet spout, including a spout housing 1 for connecting to the spout end of an external faucet, a spout perforation 2 penetrating the spout housing 1, a spout block 3 vertically disposed on the spout housing 1 within the spout perforation 2 for rising or falling within the spout perforation 2 when driven by an external force, a limiting member 4 disposed on the spout housing 1 within the spout perforation 2 and above the spout block 3 for restricting the rise of the spout block 3 when it rises to a predetermined position within the spout perforation 2, and a connection between the limiting member 4 and the spout block 3. The device includes an adsorption device for adsorbing and fixing the water outlet block 3 to the limiting member 4 when the limiting member 4 restricts the water outlet block 3 from rising; a sealing member disposed between the water outlet block 3 and the water outlet housing 1 for sealing the gap between the water outlet block 3 and the water outlet housing 1 after the adsorption device adsorbs and fixes the water outlet block 3 to the limiting member 4; a plurality of water outlet holes 5 opened on the water outlet block 3 for supplying water flow from the water outlet block 3; a water outlet channel 6 opened on the limiting member 4 for supplying water flow into the water outlet holes 5; and a driving member disposed on the water outlet block 3 for allowing the hand to remove the water outlet block 3 from the water outlet perforation 2.

[0031] The periphery of the water outlet block 3 is fitted with the water outlet perforation 2 with a clearance. The water outlet 5 can be directly installed through the water outlet block 3, or several water outlets 5 can be staggered vertically, and all of these staggered water outlets 5 are interconnected. Multiple water outlets 5 are arranged equidistantly in a ring around the water outlet block 3, or their positions can be predetermined according to design requirements. The shape of the water outlet channel 6 only needs to allow water to flow through the limiting member 4. It can be set as a ring shape that runs through the center of the limiting member 4, or multiple holes can be provided on the limiting member 4. The water outlet perforation 2 is connected to the water inlet housing.

[0032] The adsorption device includes at least one first adsorption block 7 fixedly disposed on the limiting member 4, and a second adsorption block 8 fixedly disposed on the upper end surface of the water outlet block 3 and magnetically adsorbed with the first adsorption block 7.

[0033] like Figure 1 , Figure 2 As shown, when there is only one first adsorption block 7, it is positioned at the center of the limiting member 45. At this time, the second adsorption block 8 should also be positioned at the upper center of the water outlet block 3 to improve the stability of the water outlet block 3 within the water outlet perforation 2 when the first adsorption block 7 and the second adsorption block 8 are magnetically adsorbed. When there is only one first adsorption block 7 and one second adsorption block 8, the second adsorption block 8 can be directly embedded in the upper surface of the water outlet block 3, so that when the first adsorption block 7 and the second adsorption block 8 are adsorbed and fixed, the upper surface of the water outlet block 3 is attached to the lower surface of the limiting member 4. Alternatively, to improve water flow, an extension post can be provided on the upper surface of the water outlet block 3, and the second adsorption block 8 can be embedded in the upper end of the extension post. The extension post is used to separate the distance between the limiting member 4 and the water outlet block 3, allowing water to enter the water outlet 5 more easily.

[0034] like Figure 3 , Figure 4 As shown, when there are three or more first adsorption blocks 7, each of the first adsorption blocks 7 is arranged equidistantly in a ring on the limiting member 4. When there are three or more first adsorption blocks 7, each of the first adsorption blocks 7 is arranged equidistantly in a ring on the limiting member 4. The number of second adsorption blocks 8 corresponds to the number of first adsorption blocks 7.

[0035] Alternatively, the number of second adsorption blocks 8 can be less than the number of first adsorption blocks 7, as long as it can achieve adsorption and fixation between the water outlet block 3 and the limiting member 4. For example, when four first adsorption blocks 7 are arranged in a ring at equal intervals, only two second adsorption blocks 8 can be set. When two second adsorption blocks 8 correspond to the first adsorption blocks 7, magnetic adsorption can be achieved. The shape of the first adsorption blocks 7 can be circular or arc-shaped. Its shape only needs to achieve adsorption. In this ring-shaped arrangement embodiment, an extension column can also be set to separate the distance between the limiting member 4 and the water outlet block 3, so that the water flow can more easily enter the water outlet hole 5.

[0036] The adsorption device includes a first adsorption block 7 disposed on the water outlet housing 1 and located on the periphery of the water outlet block 3, and a second adsorption block 8 disposed on the periphery of the water outlet block 3 and magnetically adsorbed with the first adsorption block 7. The first adsorption block 7 is located below the limiting member 4.

[0037] Alternatively, the limiting component 4 can be omitted, and only the first adsorption block 78 and the second adsorption block 89 can be used to achieve the effect of limiting and fixing. In this embodiment, as shown... Figure 5 , Figure 6 As shown, the first adsorption block 7 can be configured as an annular block, which is embedded or bonded to the inner wall of the water outlet housing 1, and the second adsorption block 8 is also configured as an annular block, which is embedded or bonded to the periphery of the water outlet block 3; or it can be configured as follows: Figure 6 As shown, four first adsorption blocks 7 are arranged in a ring on the inner wall of the water outlet housing 1. Four second adsorption blocks 8 are arranged in a ring at equal intervals around the water outlet block 3. When the water outlet block 3 is placed into the water outlet perforation 2 and contacts the lower end face of the limiting member 4, the first adsorption blocks 7 and the second adsorption blocks 8 are magnetically attracted, thereby fixing the water outlet block 3 in the water outlet perforation 2. The number of first adsorption blocks 7 and second adsorption blocks 8 can also be three or five, but when arranged on the periphery, there should be no less than two to prevent the water outlet block 3 from tilting during adsorption.

[0038] Both the first adsorption block 7 and the second adsorption block 8 are magnetic blocks, with opposite magnetic poles. The first adsorption block 7 is a south pole magnet, and the second magnetic block is a north pole magnet, or vice versa. The magnetic force of the first adsorption block 7 and the second adsorption block 8 is such that it can adsorb and fix the water outlet block 3 onto the limiting member 4, preventing the water outlet block 3 from being impacted by the water flow and allowing the first adsorption block 7 and the second adsorption block 8 to detach from the adsorption. Furthermore, it can detach the first adsorption block 7 and the second adsorption block 8 when the drive groove is squeezed and pulled outwards by hand. The magnitude of this magnetic force can vary depending on the size, specifications, shape, and number of arrangements; a specific limit on the magnitude of the magnetic force is not specified here, and it can be selected according to requirements.

[0039] The first adsorption block 7 is a magnetic block, and the second adsorption block 8 is a metal block that can be attracted by the magnetic block. The magnetic block of the first adsorption block 7 is fixed or snapped onto the limiting member 4 by embedding or adhesive, and the second adsorption block 8 is also fixed in the same way and installed on the upper surface of the water outlet block 3. Regarding the magnetic strength of the magnetic blocks, it is sufficient that they can attract and fix the water outlet block 3 to the limiting member 4, prevent detachment due to water pressure impact, and allow the first adsorption block 7 and the second adsorption block 8 to separate when pulled by external force. Reducing the size of the magnetic blocks, selecting magnetic blocks with different magnetic strengths, setting the shape of the magnetic blocks, or applying adhesive to the magnetic blocks and embedding them into the limiting member 4 are all acceptable as long as the above requirements are met. Since there are many options, they will not be elaborated here.

[0040] The second adsorption block 8 is a magnetic block, and the first adsorption block 7 is a metal block that can be attracted by the magnetic block. The metal block is made of iron, cobalt, or nickel. The magnetic block can be either a south pole magnet or a north pole magnet. When the first adsorption block 7 and / or the second adsorption block 8 are magnetic, the limiting member 4, the water outlet housing 1, and the water outlet block 3 are all made of materials that are not magnetically attracted.

[0041] like Figure 2 As shown, the sealing element includes an installation groove 9 formed on the water outlet housing 1 and connected to the water outlet perforation 2, and a sealing ring 10 disposed on the water outlet housing 1 within the installation groove 9. The installation groove 9 is located on the periphery of the water outlet block 3.

[0042] The number of mounting slots 9 can be one or two, and the number of sealing rings 10 corresponds to the number of mounting slots 9. The sealing rings 10 are installed in the mounting slots 9 by embedding, bonding or snapping, and the mounting slots 9 are used to restrict the sealing rings 1011 to the water outlet housing 1.

[0043] like Figure 7 As shown, the sealing element includes a mounting groove 9 formed on the periphery of the water outlet block 3 and a sealing ring 10 disposed on the water outlet block 3 within the mounting groove 9. The sealing ring 10 may also be a sealing lip or a sealing strip.

[0044] like Figure 2 , Figure 7 , Figure 8As shown, the driving component includes a driving post 11 for gripping with two fingers, disposed on the lower end face of the water outlet block 3, and an anti-slip ball 12 disposed on the lower end face of the driving post 11. The driving post 11 is vertically disposed at the lower middle of the water outlet block 3. The upper end of the driving post 11 is fixedly disposed on the lower end face of the water outlet block 3. The driving post 11 and the water outlet block 3 can be integrally formed or separately glued or hot-melt bonded. Alternatively, a rubber coating layer can be provided on the outer surface of the driving post 11 to increase the friction between the fingers and the driving post 11, thereby reducing slippage, or anti-slip ridges can be provided on the driving post 11.

[0045] The lower circumference of the water outlet housing 1 is provided with several engaging grooves 13. A threaded surface is provided on the outer circumference of the water outlet housing 1. During installation, the water outlet housing 1 is held by hand and aligned with the water outlet of the faucet. The water outlet housing 1 is then screwed to connect with the water outlet of the faucet via the threaded surface. After manual tightening, a tool can be used to engage the engaging grooves 13 and further tighten the water outlet housing 1 onto the water outlet of the faucet. This tool can be a Torx socket, a hex wrench, or flathead pliers, or any tool capable of gripping the lower end of the water outlet housing 1. The engaging grooves 13 should have the same shape as the internal teeth of the Torx socket, or be hexagonal, or consist of two symmetrically arranged S-shaped grooves.

[0046] An auxiliary annular groove 14 is annularly formed on the upper end face of the water outlet housing 1, and an auxiliary sealing ring 15 is disposed within the auxiliary annular groove 14 on the upper end face of the water outlet housing 1. The auxiliary sealing ring 15 can be a sealing material such as a rubber ring or a silicone ring.

[0047] The working principle of this utility model is as follows: When the water outlet 5 of the aerator is blocked and needs to be cleaned, the water outlet block 3 is removed from the water outlet perforation 2 by the drive component, so that the adsorption device releases the fixation of the water outlet block 3 and the limiting component 4, thereby clearing the blockage of the water outlet block 3. Then, simply place the upper end of the water outlet block 3 into the water outlet perforation 2 with the limiting component 4 facing upward, and push the water outlet block 3 upward so that it abuts against the lower end face of the limiting component 4. The lower end face of the limiting component 4 restricts the rise of the water outlet block 3. Then, the adsorption device adsorbs and fixes the water outlet block 3 and the limiting component 4, and the sealing component seals the gap between the water outlet block 3 and the water outlet housing 1. When the water flows from the water outlet end of the faucet into the water outlet perforation 2, the water flows out through the water outlet channel 6 and the water outlet 5. Compared with the cleaning process of traditional aerators, there is no need to twist frequently, the operation is simpler, and the cleaning process of the aerator can be reduced.

[0048] The channel formed on the limiting member 4 by the water outlet channel 6 can not only realize the installation of the first adsorption block 7 and the passage of water supply, but also disperse the water flow in the form of a water column before the external water flow enters the water outlet perforation 2 and enters the water outlet block 3, so that the dispersed water flow enters the water outlet hole 5, thereby making the water outlet effect of the water outlet block 3 uniform.

[0049] When the upper end of the water outlet housing 1 is connected to the water outlet end of the faucet, the gap between the upper end of the water outlet housing 1 and the water outlet end of the faucet can be sealed by the auxiliary sealing ring 15, thereby reducing the occurrence of leakage after the water outlet is installed.
