The specific embodiment

Below, the embodiment that the present invention is specialized is described.

Like Fig. 1 and shown in Figure 4, the shower nozzle 10 of this embodiment possesses nozzle body 13, and nozzle body 13 has handle portion 11, and in the set inside of nozzle body 13 stream 12 that makes current logical is arranged.The leading section of said nozzle body 13 is provided with the discharge opening 14 of tubular.Nozzle body 13 is provided with button 15, and through push this button 15 to a direction, said stream 12 is cut off, and pushes button 15 to contrary direction, and stream 12 is open.Therefore, through this button 15, shower nozzle 10 can switch between the halted state at spue state and spuing of water.On said discharge opening 14, be formed with the passage 16 that is communicated with said stream 12.Surface elements 17 is installed on the front end of shower nozzle 10.On the central part of said surface elements 17, be formed with nozzle 18, when this nozzle 18 is used for wall etc. cleaned to the outside water that spues.

Said passage 16 possesses: the part 1 16a that is positioned at discharge opening 14 centers; Be positioned at the part 2 16b of part 1 16a periphery; And the 3rd part 16c that is positioned at part 2 16b periphery.So,, make any one among the 1st～the 3rd part 16a, 16b, the 16c to be communicated with said stream 12 to select one mode through switching mechanism 19.Through the ring 20 that on the periphery of surface elements 17 and the position between the nozzle body 13, is provided with the mode that can rotate is carried out rotating operation, thereby said switching mechanism 19 is carried out change action.Knob 21 is used for carrying out rotating operation to encircling 20.

That is to say that switching mechanism 19 comprises: spherical spool 23 is incorporated in the receiving room 22; Helical spring 24 pushes away this spool 23 to closing valve (left of Fig. 1) direction bullet; And the switching part 25 integrally formed with said ring 20.So when ring 20 was rotated, switching part 25 was rotated.Through the rotation of this switching part 25, the corresponding relation between spool 23 and the not shown a plurality of valve openings is switched, and any one among the 1st～the 3rd part 16a, 16b, the 16c is connected with stream 12.

On the bottom of the perisporium 14a of said discharge opening 14 and part 1 16a, be formed with introducing port 37, introducing port 37 uses as the communication channel of introducing water from stream 12.Import to water in the part 1 16a to the direction of said nozzle 18, promptly the direction x that spues flows out from this introducing port 37.At this moment, for this water is carried out rectification, the internal diameter r of part 1 16a with from said introducing port 37 to nozzle 18 till the ratio of distance L be set to 1: 1.21～1: 3.0.The ratio of distance L and internal diameter r less than 1.21 situation under, the curtailment of part 1 16a.Therefore, even the filter screen of stating after existing 38 also is difficult in part 1 16a, realize the rectification of water, the water that spues from nozzle 18 spreads.Its result can not obtain the current 32a of straight shape (Straight).On the other hand, the ratio of distance L and internal diameter r greater than 3.0 situation under, the length of discharge opening 14 is long, the shower nozzle 10 big shapeization that becomes, the usability variation of shower nozzle 10.

In addition, on part 1 16a, between the front end of the perisporium 14a of discharge opening 14 and surface elements 17, be provided with 2 filter screens (strainer) 38 as rectification part.As shown in Figure 9, said each filter screen 38 is formed by stainless steel, is made up of circular ring 38a and its inboard net 38b.The ring 38a of 2 filter screens 38 is clamped between the perisporium 14a and surface elements 17 of discharge opening 14.The line of the employed stainless steel wire of net 38b directly is 0.1～0.3mm, for example 0.2mm.This net 38b is formed by a plurality of lines braidings in longitudinal direction and transversely extension.In addition, 2 throw the net and be provided with the interval of 1～0.5mm between the 38b.

Said each filter screen 38 is used for importing to water in the said part 1 16a from introducing port 37 towards the direction x rectification that spues.In order when suppressing the impedance that current are produced, to realize good rectification effect; When the hydraulic pressure in the discharge opening 14 is 0.025～0.075MPa (megapascal (MPa)); If the line footpath of net 38b is in the scope of 0.1～0.3mm, preferably each filter screen 38 has 30～100 orders, 70 purpose meshes for example.In addition, order is the unit of the mesh quantity in per 1 inch (25.4mm) area of expression.Be less than under the 30 purpose situation at mesh, mesh is excessive, can not fully obtain the rectification effect of water.Surpass under the 100 purpose situation at mesh, mesh is meticulous, and is excessive to the impedance that current produce, its result, and discharge-amount reduces.In addition, though even filter screen 38 has only one, also can effectively realize rectification effect, through being provided with 2, can further improve effect with upper filter screen.Be that the position relation of mesh can impact rectification effect hardly under many situation at filter screen 38.That is to say that on the direction that spues, no matter mesh is to stagger or corresponding, on rectification effect, does not see difference.In addition, though the size at the interval between many filter screens 38 can be brought influence to rectification effect hardly, however preferably should be at interval more than 0.5mm.

Like Fig. 1 and shown in Figure 3; Said nozzle 18 is set on the protuberance 26; This protuberance is outstanding towards the place ahead in the center of surface elements 17, and said nozzle 18 is made up of the 2nd recess 28 of the horizontal long groove shape in inboard the 1st recess 27 that is dome shape of surface elements 17 and the outside.Said the 2nd recess 28 is to have upper surface 28a and lower surface 28b from the inside portion to the mode of open side expansion.The 2nd recess 28 entreats the position to be communicated with said the 1st recess 27 therein.Therefore, the water that has arrived the 1st recess 27 is that membranaceous state spues with lateral magnification in the 2nd recess 28.As shown in Figure 5, between the upper surface 28a of said the 2nd recess 28 and the lower surface 28b and be positioned at and be separated by equidistant locational 28e with these

faces

28a, 28b and tilt with respect to the mode above being in the front side of the direction that spues of water with the face 26a of the front end face quadrature of said protuberance 26.In this embodiment, face 28e is 20 degree with respect to the angle θ of face 26a.Therefore, shown in double dot dash line among Fig. 1, be under the situation of level, spue towards oblique upper from the water of nozzle 18 ejections at face 26a with the front end face quadrature of said protuberance 26.

That is to say, arrive nozzle 18 from the water of said part 1 16a, from the 1st recess 27 through the 2nd recess 28 to oblique upper with straight shape and be fan-shaped membranaceous form (referring to Fig. 1 and Fig. 7) and spue.Then, the current that spue receive the air impedance, form water droplet, become the form (referring to the leftward position of Fig. 1) of diffusion type.The guttation form of this diffusion type, as shown in Figure 8, forming when the front is watched is the oval shape of growing crosswise.And, through the current 32a of straight shape, can clean narrow positions such as the seam 35 in the bathroom 33, corners 36 effectively; Through the current 32b of diffusion type, can clean the broad positions such as wall 34 in the bathroom 33 effectively.

Like Fig. 1～shown in Figure 3, on ratio nozzle 18 cyclic position in the outer part of said surface elements 17, be penetrated with a plurality of holes 43, through the thin current of multiply that spue from these holes 43, form so-called strong shower (hard shower).On the cyclic position in the outer part of the ratio hole 43 of surface elements 17, run through being provided with a plurality of holes 44,, form so-called weak shower (soft shower) through the vaporific guttation that spues from these holes 44.Then, operate, make any one of said stream 12 and the 1st of said discharge opening 14～the 3rd part 16a～16c to be connected, from the current 32a of straight shape, strong shower and weak shower optional one through knob 21 to said switching mechanism 19.

As shown in Figure 4; Be provided with indicateing arm 45 in the upper end of surface elements 17; Indicateing arm 45 is used to confirm to encircle 20 turned position; And ring 20 is provided with the mark of expression from the guttation form of nozzle 18, and mark comprises the mark 46 of representing straight current 32a, the mark 47 of the strong shower of expression and the mark 48 of the weak shower of expression.So; When knob 21 is positioned at foot; The mark 46 of straight current 32a is opposed with indicateing arm 45, with knob 21 from this position when the counter clockwise direction of Fig. 3 is rotated predetermined angular, the mark 47 of strong shower is opposed with indicateing arm 45; When the clockwise direction of Fig. 3 rotated predetermined angular, the mark 48 of weak shower was opposed with indicateing arm 45 with knob 21.And said switching mechanism 19 moves according to the position of

mark

46,47,48, as stated, from the current 32a of straight shape, strong shower and weak shower, selects any one.

The function of the shower nozzle 10 of this embodiment then, is described.

At first, as shown in Figure 7, using under the situation of shower nozzle 10, the person of utilization controls the handle portion 11 of nozzle body 13, and the ring 20 of surface elements 17 is carried out rotating operation, is set at expression and hopes that the mark 46～48 of guttation form is opposed with indicateing arm 45.For example, opposed through the mark 47 and the indicateing arm 45 that are set at strong shower, thus can enough strong shower clean health or clean hair.

Under the situation that positions such as the wall in the bathroom 33 34, seam 35, corner 36 are cleaned, make said ring 20 be positioned at foot, the mark 46 of setting straight current 32a for is opposed with indicateing arm 45.As shown in Figure 1, under this state, mobile from the 1st recess 27 of nozzle 18 to the 2nd recess 28 from the water of part 1 16a.At this moment, overlay configuration has 2 filter screens 38 between discharge opening 14 and nozzle 18, so import to water in the part 1 16a through filter screen 38 and by rectification from introducing port 37.In this case; Because the net 38b of filter screen 38 constitutes through the braided metal line, thus water around each line, unroll and form turbulent flow, through this turbulent mixing effect; On whole net 38b,, and can produce pressure differential in the front and back of filter screen 38 hardly by rectification.And the distance L from nozzle 18 to introducing port till 37 is set to 1.21～3.0 with the ratio of the internal diameter r of part 1 16a, thus from introducing port 37 import in the part 1 16a water along with towards nozzle 18 suitably by rectification.Therefore, the water that spues from nozzle 18 forms the form of straight shape, and its front is the diffusion form.

Therefore, as shown in Figure 7, make the seam 35 of shower nozzle 10 near bathroom 33, narrow such as current 32a abutment joint 35 that can be through straight shape, corner 36 is concentrated cleaning.Shower nozzle 10 is left from seam 35 or corner 36, and as shown in Figure 8, the broad wall 34 that can clean bathroom 33 through the current 32b of diffusion type efficiently cleans.

Summing up record below can be through the effect of above embodiment performance.

(1) in the shower nozzle in embodiment 10; With internal diameter r is 1 o'clock; Distance L from introducing port 37 to nozzle till 18 is set at 1.21～3.0 with the ratio of the internal diameter r of the part 1 16a of discharge opening 14, so part 1 16a forms the shape that is enough to the current of its inside are carried out rectification.And, dispose filter screen 38 at the upstream side of nozzle 18 as rectification part.Therefore, the water that imports to part 1 16a from introducing port 37 is by rectification, and direction x flows out to spuing.And the water that spues from nozzle 18 demonstrates from nozzle 18 and is rectified into straight membranaceous guttation form, demonstrates the radial guttation form that diffuses at its front end.

Thus, according to the shower nozzle 10 of embodiment, can utilize the current 32a of straight shape effectively the narrow positions in the bathroom 33 to be cleaned, and utilize the current 32b of diffusion type effectively broad position to be cleaned.

(2) rectification part is made up of filter screen 38; Filter screen 38 directly is that the stainless steel wire braiding of 0.1～0.3mm forms by line; Have 30～100 purpose meshes, so in can the circulation impedance when suppressing water, carry out rectification from discharge opening 14 to the direction x that spues effectively through filter screen 38.

(3) rectification part is made up of 2 (many) filter screens 38, so water during through first filter screen 38, by the direction x rectification that spues to nozzle 18, the water that obtains rectification is during through second filter screen 38, further by the direction x rectification that spues to nozzle 18.Therefore, can further improve the rectification effect of water.

(4) mode of shower nozzle 10 most above direction people's head or health water supply is used.Therefore, as shown in Figure 6, shower nozzle 10 form under erectility its upper side towards below.Therefore, surface elements 17 also is configured to towards the below, and tiltedly below is pointed in the

hole

43,44 that strong shower and weak shower are used.But the water that spues from nozzle 18 is used to the cleaning of wall etc.Therefore, point in the formation of the direction identical, under the situation of cleaning wall, especially under the situation on the top of cleaning wall, need shower nozzle 10 be remained towards the top with

hole

43,44 at nozzle 18.In this case, bring bigger burden for upper arm or wrist, be not easy to carry out washing and cleaning operation.With respect to this, the nozzle 18 of this embodiment constitutes to the oblique upper water that spues.Therefore, the demand that shower nozzle 10 is remained towards the top reduces, and can easily carry out washing and cleaning operation.

[embodiment 1]

Then,,, condition is carried out various changes, test to the internal diameter r of part 1 16a and from the relation between the distance L of introducing port 37 to nozzle 18 about the shower nozzle 10 of above-mentioned embodiment.

That is to say, the internal diameter r of part 1 16a is reached from the change as shown in table 1 of the distance L of introducing port 37 to nozzle 18.Then, supplied with the running water of predetermined pressure to nozzle 18 from stream 12.And, with following criterion visual valuation guttation form.Their result is started from table 1.In addition; In this case; The direction of growing crosswise of the 2nd recess 28 of nozzle 18, promptly, side-to-side dimensions (left and right directions of Fig. 3) is of a size of 10～30mm (for example 20mm), is of a size of 2～6mm (for example 4mm) up and down; Border between the 1st recess 27 and the 2nd recess 28 be of a size of 1～5mm (for example 2.5mm) up and down, the side-to-side dimensions on border is 3～10 (for example 7mm).

" zero " expression has obtained the situation of straight current 32a, and " * " representes unavailable situation.

[table 1]

Result as shown in table 1 is under the situation of for example 8mm at the internal diameter r of part 1 16a, as long as be more than the 10mm, to that is to say from the distance L of introducing port 37 to nozzle 18, as long as the ratio of internal diameter r and distance L is 1: 1.25, has just obtained straight current 32a.Under the situation of distance L,,, fail to obtain the current 32a of straight shape so spread immediately after current spue from nozzle 18 owing to can not carry out rectification effectively less than 10mm.

In addition, be under the situation of 15mm at the internal diameter r of part 1 16a, needing only from the distance L of introducing port 37 to nozzle 18 is more than the 19mm, to that is to say, as long as said ratio is 1: 1.27, has just obtained straight current 32a.In distance L is under the situation below the 18mm, spreads immediately after current spue from nozzle 18, fails to obtain the current 32a of straight shape.

In addition, be under the situation of 19mm at the internal diameter r of part 1 16a, needing only from the distance L of introducing port 37 to nozzle 18 is more than the 23mm, to that is to say, as long as ratio is 1: 1.21, has just obtained straight current 32a.In distance L is under the situation below the 22mm, spreads immediately after current spue from nozzle 18, fails to obtain the current 32a of straight shape.

Result shown in the table 1 representes, as long as the ratio of said distance L and internal diameter r is more than 1.21: 1, can access the current 32a of straight shape.But if the ratio of distance L and internal diameter surpasses 3: 1, then said distance L is elongated, and shower nozzle 10 maximizes, and is difficult for using.

In addition; Be of a size of at nozzle 18 under the situation of said numerical value (side-to-side dimensions that is of a size of 2.5mm, border up and down that the direction of growing crosswise of the 2nd recess 28 is of a size of 20mm, be of a size of the border of 4mm, the 1st recess 27 and the 2nd recess 28 up and down is 7mm); When the hydraulic pressure in the discharge opening 14 is lower than 0.03MPa, though can access straight current 32a, yet; A little less than the flow of water of straight current 32a, also do not become disperse state and just fall.Therefore, the hydraulic pressure in the discharge opening 14 need be more than 0.03MPa, preferably more than 0.05MPa.At this, when said size increased, the hydraulic pressure in the discharge opening 14 descended, so in this case, in order to obtain straight current 32a, the water supply that needs to increase running water is pressed.In addition, follow the hydraulic pressure in the discharge opening 14 to increase, the length alpha of straight current prolongs.

In addition, can above-mentioned each embodiment be changed as follows and implement.
