Detailed Description
In an embodiment, please refer to the drawings, the shower head for improving the impact force of water flow of the present invention includes a shower head body 1 and a water outlet member, the water outlet member is specifically a water outlet cover 2, which is locked on the shower head body 1 through a screw 3, and a plurality of O-ring seals 4 are fitted between the water outlet cover 2 and the shower head body 1, the shower head body 1 includes a shower head handle and a shower head, but is not limited thereto. A plurality of water outlet units are distributed on the water outlet surface cover 2, and each water outlet unit comprises a plurality of water outlet holes 21 and a convex guide plate 22; the guide plate 22 is located on one side where the water outlet end of the water outlet hole 21 is located (i.e., the guide plate 22 is located on the front surface of the water outlet cover 2), and the water outlet holes 21 of the water outlet unit are distributed on two sides of the surface where the guide plate 22 is located, so that water flowing out through the water outlet holes 21 can flow along the guide plate 22 and finally converge into one strand.
In this embodiment, the water outlet hole 21 is an accelerating hole, specifically, a conical accelerating hole, and the diameter (i.e., diameter) of the accelerating hole is gradually smaller along the water flow direction. The aperture D of the water outlet end of the water outlet hole 21 is 0.5 mm-1.2 mm, and the preferred value is 0.85 mm.
In this embodiment, the number of the water outlet holes 21 of the water outlet unit is two, but not limited thereto. The two water outlet holes 21 are symmetrically distributed on two sides of the surface where the guide plate 22 is located, and the distance A between the water outlet end of each water outlet hole 21 and the guide plate 22 is 0-0.8 mm. The deflector 22 is the straight wall body, the thickness C of deflector 22 is 0.5mm ~ 1.15mm, the interval (the width of deflector 22 promptly, the broadside of deflector 22 along the rivers direction) at the inside and outside both ends of deflector 22 is 0.5mm ~ 3mm, and the inner of deflector 22 indicates the deflector to be close to the one end of apopore, the outer end of deflector 22 guides the deflector to deviate from the one end of apopore.
Referring to fig. 8 and 9, fig. 8 is a comparison graph of water outlet effects of the present invention at different center distances when the water inlet pressure is 0.01 MPa; fig. 9 is a comparison graph of water outlet effects of different center distances when the water inlet pressure is 0.03MPa, the center distance of the double holes refers to the distance between the centers of the two water outlet holes 21, and as can be seen from fig. 8 and 9, no matter the water inlet pressure is 0.01MPa or 0.03MPa, the spray distance is farthest when the center distance of the double holes is 1.6mm, the water pressure is low, the spray distance is obvious, the spray distance is shorter when the center distance of the double holes is 1.2mm, and the spray distance is shorter when the center distance of the double holes is less than 1.2mm, so that the spray device is not suitable for use. Therefore, the optimal value range of the center distance of the double holes is 1.2 mm-1.6 mm. When the aperture of the water outlet end of each water outlet hole is 0.85mm, the distance B between the water outlet ends of the two water outlet holes (namely the difference between the center distance of the double holes and the aperture of the water outlet end) is 0.35 mm-1.15 mm, and the thickness C of the fixed guide plate is 0.5 mm-B in consideration of the feasibility of the process, namely the thickness C of the guide plate is 0.5 mm-1.15 mm.
Referring to fig. 10, fig. 10 is a comparison graph of the water outlet effect of the present invention under different outlet lengths when the water inlet pressure is 0.01MPa, the outlet length is the distance between the inner end and the outer end of the guide plate 22, the water outlet area basically does not change with the increase of the outlet length, but the water outlet speed and the water outlet force gradually decrease, the water spraying distance of the shower head tends to be shortened, and the water outlet distance is basically the same after 3 mm. Therefore, in consideration of process feasibility, the optimal range of the outlet length (i.e., the distance between the inner and outer ends of the guide plate 22) is set to 0.5mm to 3 mm.
In this embodiment, the water outlet unit further includes a protruding ring 23 located at one side of the water outlet end of the water outlet hole 21 (i.e., the front surface of the water outlet cover 2), the guide plate 22 is located in the protruding ring 23, and two ends of the guide plate 22 located in a direction perpendicular to the water flow direction (i.e., the length direction of the guide plate 22, and the long side of the guide plate 22 perpendicular to the water flow direction) are integrally connected to the inner wall surface of the protruding ring 23. The inner diameter (i.e. the inner diameter) of the convex ring 23 is much larger than the diameter of the outlet end of the water outlet hole 21, and the outlet end of each water outlet hole 21 of the water outlet unit falls within the inner range of the convex ring 23, so that the outlet end of each water outlet hole 21 is visible. Due to the arrangement of the convex ring 23, the guide plate 22 can be conveniently machined, the strength of the guide plate 22 can be improved, and the guide plate 22 is not easy to damage.
According to the shower head capable of improving the impact force of water flow, when water flows out, the water flow enters from the two water outlet holes 21 of each water outlet unit and is accelerated through the water outlet holes 21 and then sprayed out to form the two water flows 13 and 14, the speeds of the two water flows 13 and 14 are v15 and v17 respectively, the force values of the two water flows are F16 and F18 respectively, and when the two water flows 13 and 14 pass through the guide plate 22, the two water flows tend to flow along the surface of the protruding guide plate 22 due to the wall attachment effect or the coanda effect so as to ensure that the shape of the sprayed water is in a linear trend. The guide plate 22 is combined into a water flow 19, the flow speed of the water flow 19 is v20, the impact force is F21, v 20-v 15-v 17, and F21-F16 + F18.
Compared with the single-hole shower head in the prior art (that is, each water outlet unit of the shower head is a single water outlet hole, as shown in fig. 1), under the condition of the same water pressure and water outlet area (that is, the water outlet area of a single water outlet hole of the single-hole shower head is equal to the sum of the water outlet areas of two water outlet holes 21 of the present invention), because the water outlet hole 21 of the present invention is smaller and the back pressure is larger, the pressure difference P10 of the water outlet surface cover 2 of the present invention is greater than the pressure difference P25 of the water outlet surface cover of the shower head in the prior art. Meanwhile, under the condition of the same water outlet area and the same water inlet pressure P30, the flow Q29 of the water flow 19 is larger than the flow Q32 of the water flow 26 of the shower head in the prior art, so the flow speed v20 is larger than v27, and v27 refers to the flow speed of the shower head in the prior art. From F ═ ρ qv (ρ is fluid density, q is flow rate, and v is velocity), the impact force F21 > F28 of the water flow. That is, the water flow 26 has the same area as the water flow 19, the water flow 19 is formed by converging two small holes, the water flow 26 flows out from a hole twice as large, the water flow 26 has no wall attachment effect, and the effluent is subjected to gravity G and has a falling tendency, as shown in fig. 2. The water profile of the water stream 19 will be relatively better maintained due to the coanda effect and the distance of the spray will be greater as shown in figure 7.
The flow rate and back pressure of the water outlet holes of the shower head of the present invention (each water outlet unit comprises two water outlet holes, which are referred to as double holes for short) and the flow rate and back pressure of the water outlet holes of the shower head of the prior art (each water outlet unit of the shower head is a single water outlet hole, which is referred to as single hole for short) are further described in a table form below under the same water inlet pressure and the same water outlet area.
Therefore, under the action of the same water inlet pressure P30, compared with a common shower head with the same water outlet area, the shower head water has higher flow and higher speed through porous pressurization, and the water shape of the shower head water can be kept relatively straighter under the action of gravity G and the impact force of water spray is larger by combining the wall attachment effect. Therefore, compared with the shower head in the prior art, the shower head has higher water impact force and longer spraying distance under the condition of lower water pressure, so that a user can shower more comfortably.
In other embodiments, a converging portion is disposed at an end of the guide plate (i.e., an end of the guide plate facing away from the water outlet hole), and a cross section of the converging portion is convex-pointed, so that a water flow converging effect is better.
The above embodiments are only used to further illustrate the shower head for increasing the impact force of water flow, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention fall within the protection scope of the technical solution of the present invention.
