Description

Technical Field

[0001] The present invention relates to the technical field of shower devices, and particularly to a shower head. Background Art

[0002] A shower head is a commonly used shower device in people's daily life. Existing shower heads mostly adopt the method of discharging water through small holes. After using for a period of time, the phenomenon of blockage of the water outlet holes often occurs, resulting in uneven water lines sprayed or abnormal sounds when discharging water; however, once the small-hole water discharge method is blocked, it is very difficult to clean. For this reason, a Chinese invention patent with the patent number CN201810006248.7 discloses "A Shower Head with a Cleaner". This shower head mainly consists of a rear cover and a front cover; the shower head with a cleaner further includes a guiding device and a cleaner. The middle part of the cleaner is a positioning ring, and more than two hollow rotors extending outwards are evenly arranged on the outer wall of the positioning ring. An inwardly sunken water inlet groove is provided on the wall surface of the positioning ring facing inwards; the guiding device divides the water storage cavity into a water inlet cavity and a water spraying cavity, and a diversion hole is provided on the guiding device. The cleaner is arranged outside the guiding device, and the cleaner is provided with hollow rotors. A water outlet spray hole is provided on one side wall of each rotor. After water enters the guiding device, it flows into the rotor through the diversion hole and then sprays outwards from the water outlet spray holes on the rotor. The water sprayed out from all the water outlet spray holes on the rotors forms a forward or reverse water flow, which pushes the cleaner to rotate forward or reverse. The cleaning device arranged below the rotor cleans the water inlet end of the water spraying hole, so that scale is not easily formed; this shower head uses the cleaner to clean the water spraying hole when discharging water, thereby preventing the water spraying hole from being blocked. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide another shower head that is not easily blocked and is easy to clean in view of the above technical status.

[0004] The technical solution adopted by the present invention to solve the above technical problem is as follows: This shower head includes a body with a central hole and a flow guiding member arranged in the central hole of the body for guiding water flow, and is characterized in that:

[0005] The body is in a disc shape, and a plurality of radially distributed water guiding grooves extending outwards from the axis of the central hole are opened on the lower surface. Each of the water guiding grooves opens downwards, and the head end of each water guiding groove is communicated with the flow guiding member, and a guiding arc surface is arranged at the tail end of each water guiding groove.

[0006] To more evenly spray water outwards, preferably, the cross-section of the water guide groove is an inverted V shape, including a long groove where the guiding arc surface is adjacent to the peripheral edge of the body, a short groove where the guiding arc surface is adjacent to the central hole of the body, and a middle groove where the guiding arc surface is located between the peripheral edge of the body and the central hole of the body. Dividing the water guide groove into a long groove, a middle groove, and a short groove can enable water to be sprayed out at various positions of the disc-shaped body, thereby achieving uniform water discharge.

[0007] To better fix the flow guide member on the body, preferably, the head of the flow guide member can pass through the central hole of the body and is provided with a water inlet. Correspondingly, the tail of the flow guide member is provided with a water outlet communicating with the head end of the water guide groove, and the tail end of the flow guide member is provided with a flanging turned outwards, so that the tail end of the flow guide member is restricted below the body.

[0008] Furthermore, a fixing member for fixing the flow guide member in the central hole is further provided on the upper surface of the body.

[0009] Furthermore, the head of the flow guide member is provided with an external thread; correspondingly, the fixing member is provided with an internal thread; in the state where the fixing member is screwed with the head of the flow guide member, the flow guide member is fixed in the central hole of the body.

[0010] Since the water flowing out of the water outlet of the flow guide member can flow in various directions, to make the water flow better into the water guide groove, preferably, the shower head further includes an O-ring sleeved on the flow guide member and used for sealing. Correspondingly, the flow guide member is provided with a mounting groove for mounting the O-ring above the water outlet; and a sealing ring placed on the flanging and below the water outlet; under the action of the O-ring and the sealing ring, the water flowing out of the water outlet flows into each water guide groove.

[0011] To prevent the sealing ring from moving, preferably, at least one convex ring is protruded on the flanging. In the state where the sealing ring is placed on the flanging, the convex ring can increase the friction force of the sealing ring, so that the sealing ring does not slip.

[0012] Compared with the prior art, the advantages of the present invention are as follows: Through the design of multiple downward-opening water guide grooves, the water flow is guided by the flow guide member, flows into each water guide groove, and is sprayed downward under the guidance of the corresponding guiding arc surfaces; in this way, the water flow guided by the flow guide member is directly sprayed outwards from the water guide groove without passing through the common water spraying holes, making it easier to clean the water scale, not easily blocking the water outlet channel, not easily affected by the water scale, and at the same time, the overall design is ingenious, the structure is simple, and it is easy to implement.

[0018] The present invention will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0019] In the description and claims of the present invention, terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention. However, these terms are used here only for the convenience of description and are determined based on the exemplary orientations shown in the drawings. Since the embodiments disclosed by the present invention can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity.

[0020] As Figures 1 to 5 shown, it is a preferred embodiment of the shower head of the present invention. The shower head of this embodiment includes a body 1, a flow guide member 2, a fixing member 3, an O-ring 4, and a sealing ring 5.

[0021] Among them, the body 1 is disc-shaped and has a central hole 11. A plurality of water guide grooves 12 radially distributed outward from the axis of the central hole 11 are formed on the lower surface of the body 1. Each water guide groove 12 opens downward, and the head end of each water guide groove 12 is communicated with the flow guide member 2, and a guiding arc surface 121 is arranged at the tail end; the flow guide member 2 is used to guide the water flow. The head 21 of the flow guide member 2 can pass through the central hole 11 of the body 1 and is provided with a water inlet 23. Correspondingly, a water outlet 24 communicated with each water guide groove 12 is formed at the tail 22 of the flow guide member 2. A flanging 25 turned outward is arranged at the tail end 221 of the flow guide member 2, so that the tail end 221 of the flow guide member 2 is limited below the body 1. Under the guidance of the flow guide member 2, the water flow flows into each radially distributed water guide groove 12 and is ejected downward under the guidance of the corresponding guiding arc surfaces 121. An external thread is also arranged on the head 21 of the flow guide member 2; the fixing member 3 is arranged on the upper surface of the body 1, and the fixing member 3 is provided with an internal thread screwed with the external thread of the head 21 of the flow guide member 2. The flow guide member 2 is fixed in the central hole 11 of the body 1 by screwing with the fixing member 3; the O-ring 4 is sleeved on the flow guide member 2 and is used for sealing. Correspondingly, an installation groove 26 for installing the O-ring 4 is formed above the water outlet 24 of the flow guide member 2; in addition, the sealing ring 5 is placed on the flanging 25 and is located below the water outlet 24. Correspondingly, two convex rings 251 are convexly arranged on the flanging 25. In the state where the sealing ring 5 is placed on the flanging 25, the convex rings 251 can increase the friction force of the sealing ring 5, so that the sealing ring 5 does not slip. Among them, since the water flow flowing out of the water outlet 24 of the flow guide member 2 can flow in all directions, under the action of the O-ring 4 and the sealing ring 5, the water flow flowing out of the water outlet 24 can only flow into each water guide groove 12, so that the water flow is more concentrated and ejected outward from the water guide groove 12.

[0022] In order to make the water flow eject outward at each position of the body 1, the following structure is adopted in this embodiment: the cross-section of the water guide groove 12 in this embodiment is an inverted V shape, including a long groove 122 adjacent to the periphery of the body 1 of the guiding arc surface 121, a short groove 123 adjacent to the central hole 11 of the body 1 of the guiding arc surface 121, and a middle groove 124 of the guiding arc surface 121 located between the periphery of the body 1 and the central hole 11 of the body 1. Dividing the water guide groove 12 into the long groove 122, the middle groove 124 and the short groove 123 can make the water flow eject at each position of the disc-shaped body 1, and then realize uniform water output.

[0023] In summary, the use process of this shower head is as follows: As Figure 1 shown by the arrow in, the water flow enters the flow guide member 12 from the water inlet 23 at the head 21 of the flow guide member 12 and flows out from the water outlet 24; since the O-ring 4 seals above the water outlet 24 and the sealing ring 5 seals below the water outlet 24, the water flow can only flow into the water guide groove 12, and then is ejected downward under the guidance of the guiding arc surface 121.
