Description

Technical Field

[0001] The utility model relates to the technical field of bathroom products, in particular to a water outlet, a water outlet device and a shower head. Background Art

[0002] At present, the inner holes of conventional shower heads are mostly circular holes with a single function and no additional functions. When the water pressure changes, the water outlet cannot adjust the water impact force. Conventional round-hole water outlet nozzles have a strong impact force under low pressure. The water outlet diameter is 0.5mm, the number is about 100, the single water outlet area is 0.19625mm², and the total water outlet area is 19.625mm². When the water pressure increases, the ordinary round-hole water outlet nozzle cannot increase the water outlet area greatly due to the elasticity and shape limitations of the material, which causes the water outlet flow rate to increase sharply. At the same time, the water line is thinner, forming a pricking feeling. The smaller the diameter of the conventional round-hole water outlet nozzle, the faster the flow rate, but it is more likely to be blocked and difficult to clean. Utility Model Content

[0003] The utility model aims to solve at least one of the above technical problems in the related art to a certain extent. To this end, the utility model provides a water outlet nozzle, which can change the water outlet area and adjust the water outlet impact force according to the change of water pressure within a certain water pressure range.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] The utility model also provides a water outlet device having the water outlet nozzle.

[0006] The utility model also provides a shower head with the water outlet nozzle.

[0007] The water outlet spout according to the first aspect of the present invention comprises a water outlet spout body, the interior of the water outlet spout body is a cavity for water to flow out, the water outlet spout body has a water inlet end and a water outlet end, the water outlet end is provided with two or more water outlet through holes, at least two of the water outlet through holes are connected by a gap, the gap runs through the interior and the exterior of the water outlet body, and the water outlet body is made of elastic material.

[0008] The water outlet nozzle according to the embodiment of the utility model has at least the following beneficial effects:

[0009] 1. Use an elastomeric water spout with more than two water outlet holes on the water outlet end of the water spout, and gaps connecting the water outlet holes. This arrangement allows the water flow area of ​​the water outlet to change with the change of water pressure. In the case of no water pressure or low water pressure, the gaps between the water outlet holes are closed or the gap width is extremely small, and each water outlet hole discharges water separately. Since the water outlet holes are small and the water outlet area is small, the water outlet still has impact force and there are more water lines. When the water pressure increases to a certain value, the gaps between the water outlet holes open, and the water flow between the gaps attracts the water lines of each hole and merges them into a thicker water column. At the same time, due to the opening of the gaps, the water outlet area of ​​the water outlet increases, which will not cause excessive impact force and provide a good shower experience.

[0010] 2. The combination of the water outlet hole and the gap can adopt the conventional round hole silicone molding method + die-cut silicone process to reduce the difficulty of the molding process. At the same time, when the gap is not opened, the water outlet hole is still a conventional circle or quasi-circular, which is conducive to the control of the water shape and the direction of the water line.

[0011] 3. The two water outlet holes of a single water outlet are connected by a gap, which makes it easier to knead and squeeze out the blocking foreign matter, which is beneficial to cleaning the water outlet.

[0012] 4. The number of water lines will change according to different pressures. When the water pressure is low, there will be multiple thin lines of water, the water lines are denser, and the cleaning range is more comprehensive. When the pressure increases to the point where the gaps open, the water flows from each water outlet hole and the gaps will merge into a single line of thick water, and the water lines will not feel prickly due to being too thin.

[0013] According to some embodiments of the utility model, when the water pressure is lower than a set value, the slit is in a closed state. When there is no water pressure or low water pressure, the slit opening width is 0, and water only flows out from the water outlet hole.

[0014] According to some embodiments of the utility model, when the water pressure is lower than a set value, the opening width of the slit is smaller than the aperture of the water outlet hole. In the state of no water pressure, the opening width of the slit is 0, and in the state of low water pressure, the slit can remain closed, or the slit opens to a very small width, but the width is not enough to merge the water flows from various places into a single thick line of water.

[0015] According to some embodiments of the utility model, the cross-sectional area of ​​the cavity gradually decreases from the water inlet to the water outlet. The cavity for water to flow out is conical, wide at the top and narrow at the bottom, which is conducive to increasing the water pressure flowing to the water outlet.

[0016] According to some embodiments of the utility model, the outer peripheral wall of the water inlet end is provided with a flange in the radial direction. The flange plays a limiting role, making it easier for the water outlet to be installed on the through hole of the lower cover of the shower head.

[0017] According to some embodiments of the utility model, the water outlet through hole is a circular hole or a special-shaped hole. The circular hole is conducive to the control of the water shape and the direction of the water line, and is easy to process. The water outlet through hole can also be a circular special-shaped hole, such as a water drop shape, an ellipse.

[0018] According to some embodiments of the utility model, the water spout body is made of silicone material. The silicone material ensures that the gap has a certain degree of elastic deformation ability and good gap sealing. In addition, the silicone itself has the advantages of high temperature resistance, easy cleaning, environmental protection, non-toxicity, and wear resistance.

[0019] According to some embodiments of the utility model, when the number of the water outlet holes is greater than or equal to 3, the water outlet holes are distributed in a circular array, and the gap extends from each water outlet hole to the circular surface surrounded by the circular path of the circular array and intersects at any point on the circular surface.

[0020] The water outlet device according to the second aspect of the embodiment of the utility model includes the water outlet nozzle.

[0021] The shower head according to the third aspect of the present invention comprises an upper cover, a lower cover and the water outlet, wherein the upper cover is connected with the lower cover to form a water cavity, a plurality of mounting holes are formed on the lower cover, and the water outlet is arranged between the upper cover and the lower cover and penetrates the mounting holes.

[0022] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] 1-2, a water spout 100 includes a water spout body, the interior of the water spout body is a cavity for water to flow out, the water spout body has a water inlet end and a water outlet end, and the water outlet end is provided with two or more water outlet through holes 110, at least two of the water outlet through holes 110 are connected by a gap 120, and the gap 120 runs through the interior and the exterior of the water spout body, and the water spout body is made of elastic material.

[0035] An elastomeric water spout is used, and the water outlet end of the water spout is provided with more than two water outlet holes 110, and the water outlet holes 110 are connected by gaps 120. Such a setting can realize that the water flow area of ​​the water outlet changes with the change of water pressure. In the case of no water pressure or low water pressure, the gaps 120 between the water outlet holes 110 are closed or the width of the gaps 120 is extremely small, and each water outlet hole 110 discharges water separately. Since the water outlet holes 110 are small and the water outlet area is small, the water outlet still has impact force and there are more water lines. When the water pressure increases to a certain value, the gaps 120 between the water outlet holes 110 open, and the water flow between the gaps 120 attracts the water lines of each hole and merges them into a thicker water column. At the same time, since the gaps 120 are opened, the water outlet area of ​​the water outlet increases, which will not cause excessive impact force, and the shower experience is good.

[0036] The number of water lines will change according to different pressures. When the water pressure is low, there will be multiple thin lines of water, as shown in FIG6 . The water lines are denser and the cleaning range is more comprehensive. When the pressure increases to open the gap 120 , the water flows of each water outlet hole 110 and the gap 120 will merge into a single line of thick water, as shown in FIG7 . The water line will not feel prickly due to being too thin.

[0037] Referring to Figure 1, taking a single strip-shaped water outlet with two water outlet holes + gap 120 (slit) as an example, the diameter of the two water outlet holes 110 is 0.4mm, the area of ​​a single hole is 0.1256mm², the water outlet area of ​​a single water outlet is 0.2512mm², 60 water outlets are set, a total of 120 water outlet holes 110, and the total water outlet area is 15.072 mm². Under the condition of better water outlet intensity and smaller total water outlet area requirements, more water outlet holes and better shower range are required. The gap 120 (slit) between the two holes is processed by post-processing die cutting. Under no water pressure or low water pressure, the opening width of the gap 120 is 0, that is, closed state, and the pressure opening value of the gap 120 is controlled by the hardness and thickness of the water outlet material and the distance between the two holes. Set the distance between the two holes to 1.2mm, the length of the gap 120 to 0.8mm, the width of the gap 120 to X, and the water outlet area of ​​a single water outlet S=0.2512+0.8X. According to the flow rate relationship Q=V*S (Q: flow rate, V: flow rate, S: water flow area), when the pressure increases, the gap 120X becomes larger, the water outlet area increases, and the water outlet area is positively correlated with the pressure, which is conducive to adjusting the water outlet speed. If the flow rate Q remains unchanged, the water outlet area increases and the flow rate decreases.

[0038] In some specific embodiments of the present invention, referring to FIG. 3 , there are three water outlet through holes 110 arranged in a line, and the water outlet through holes 110 are connected by gaps 120 .

[0039] In a further embodiment of the utility model, when the number of water outlet through holes is greater than or equal to 3, each water outlet through hole 110 is distributed in an annular array, and the slits 120 extend from each water outlet through hole 110 to the circular surface surrounded by the annular path of the annular array and intersect at any point on the circular surface, such as the center of the circular surface, which is the center of the annular array. Referring to Figure 5, the number of water outlet through holes 110 is three, four or five, and each water outlet through hole 110 is distributed in an annular array, and the slits 120 extend from each water outlet through hole 110 to the center of the annular array and intersect at the center.

[0040] In some specific embodiments of the present invention, when the water pressure is lower than the set value, the slit 120 is in a closed state, or the opening width of the slit 120 is smaller than the aperture of the water outlet through hole 110. In the state without water pressure, the opening width of the slit 120 is 0, and in the state of low water pressure, the slit 120 can remain in a closed state, or the slit 120 opens to a very small width, but the width is not enough to merge the water flows at various places into a single thick line of water.

[0041] In some specific embodiments of the utility model, the cross-sectional area of ​​the cavity gradually decreases from the water inlet to the water outlet. The cavity for water to flow out is conical, wide at the top and narrow at the bottom, which is conducive to increasing the water pressure flowing to the water outlet.

[0042] In some specific embodiments of the present invention, a flange 130 is radially arranged on the outer peripheral wall of the water inlet end. The flange 130 serves as a limiter to facilitate the installation of the water outlet nozzle on the through hole of the shower head lower cover 300.

[0043] In some specific embodiments of the utility model, the water outlet through hole 110 is a circular hole or a special-shaped hole. The circular hole is conducive to the control of the direction of the water pattern and the water line, and is easy to process. The water outlet through hole 110 can also be a circular special-shaped hole, such as a water drop shape, an ellipse. Referring to FIG. 4 for the scheme of the special-shaped hole, the shape of the water outlet through hole 110 is a water drop shape.

[0044] In some specific embodiments of the present invention, the water spout body is made of silicone material. The silicone material ensures that the gap 120 has a certain degree of elastic deformation ability, and the gap 120 has good sealing performance. In addition, silicone itself has the advantages of high temperature resistance, easy cleaning, environmental protection, non-toxicity, and wear resistance.

[0046] A shower head, referring to FIG. 8 , includes an upper cover 200 , a lower cover 300 and a water outlet 100 . The upper cover 200 is connected to the lower cover 300 to form a water cavity. The lower cover 300 is provided with a plurality of mounting holes 310 . The water outlet 100 is disposed between the upper cover 200 and the lower cover 300 and is passed through the mounting holes 310 .
