Guide part 123c is arranged circumferentially being penetrated in vertical direction by multiple (in this case 8) cylinder element in the way of cone shape stream wall 23a. Thus, guide part 123c is formed generally, and rectification guttation mouth 21 side is thinner compared with jet 11 side. In the present embodiment, especially, guide part 123c is made up of the 1st region 123c1 formed towards rectification guttation mouth 21 with certain width from jet 11 side and the 2nd region 123c2 gradually attenuated in downstream compared with the 1st region 123c1.
Additionally, what be directed to that portion 123c divides divides stream 23d after forming upstream side along the region 123c2 of above-mentioned 1st region 123c1 and the 2 with certain width, gradually extend in downstream. And, divide stream 23d and be configured in the upstream side of necking part 23b, merge into a stream.
So, being directed to the portion 123c division stream 23d divided is following composition, i.e. its regulation is not advanced tortuously from jet 11 towards the current of the water of rectification guttation mouth 21 on stream wall 23a, additionally, do not converge with the water flow through in stream 23d that divides at other. Guide part 123c is following composition ideally, i.e. regulation water advances towards the circular cone center position of cone shape stream wall 23a with linearity, in other words, specifies towards the central shaft of gas-liquid interface described later with beeline.
Spray stream 24 is formed from guiding the stream of water in the jet 11 of outer circumferential side towards spray guttation mouth 22. Specifically, in the 2nd portion 20, spray stream 24 is configured in the outside of rectification stream 23 across stream wall 23a. Spray its upstream side of stream 24 is circumferentially configured with the vertical hole 124a (adverse current preventing portion) of multiple tubular, possessing bubble in downstream is mixed into water reservoir 24b2 simultaneously, described bubble is mixed into water reservoir 24b2 by annular circle-shaped for the through one-tenth in bottom in the 2nd portion 20, temporarily to accumulate water.
The mode that since constituting the vertical hole 124a of spray stream 24, the water of blowing loophole 11 flows down immediately below injection direction is positioned on the position on the periphery of jet 11, and is provided with multiple (in this case at equal intervals 8) on the outer circumferential side in the 2nd portion 20. Further, since the wall of vertical hole 124a is to prominent in rectification stream 23, therefore play a role as guide part 123c in rectification stream 23.
On the other hand, spray other element of stream 24 and bubble are mixed into water reservoir 24b2 and are then formed in the part of cone shape inclination at the stream wall 23a of rectification stream 23, and the direction, inner side to the 2nd portion 20 is prominent and volume enlargement. This part becomes the state prominent to rectification stream 23 side, thus in rectification stream 23 side, forming necking part 23b across stream wall 23a.
Additionally, bubble is mixed into the water reservoir 24b2 stream wall 23a in side downstream in the part of rectification guttation mouth 21 extension being provided with screens 21a, have in circular guide part 24c. This guide part 24c is configured to overlapping at least partially with the cross section of vertical hole 124a. Thus, in the 2nd portion 20 rotating guttation mouth cap 1, and during from rectification state to spray state switching, first pass through from the vertical hole 124a of spray stream 24 water flowed into and bump against with guide part 24c to underface flowing. It addition, in the present embodiment, it is preferable that bump against from the major part of the vertical hole 124a water flow through with guide part 24c, namely less than the water bumped against with the guide part 24c water not bumped against. Additionally, in the present embodiment, it is preferable that form guide part 24c with the component identical with spray guttation mouth 22, in order to formed as the part in the 2nd portion 20, and form guide part 24c and spray guttation mouth 22 regularly.
Spray stream 24 is formed by being mixed into water reservoir 24b2 by such vertical hole 124a and bubble, the flow path cross sectional area that among spray stream 24, can make upstream side (vertical hole 124a) is less than the flow path cross sectional area of downstream (bubble is mixed into water reservoir 24b2). Thus, when spraying guttation, can make to be mixed into water reservoir 24b2 from vertical hole 124a towards bubble to the water that spray stream 24 stream comes from jet 11 effectively to spray such that it is able to prevent the water in spray stream 24 because the flow path resistance of spray guttation mouth 22 to jet 11 side adverse current. It addition, the flow path cross sectional area of vertical hole 124a is formed more slightly greater than jet 11, in order to forming the space for importing air about.
On the other hand, if increase the flow of water from the vertical hole 124a water sprayed when spraying guttation, then owing to being mixed into water reservoir 24b2 at the bubble accepting this water, the bubble vibration of gas-liquid interface that is mixed in water reservoir 24b2 to be formed increase, therefore the 2nd portion 20 becomes easily mobile (easily rotating). When the 2nd portion 20 moves, then cause that the position being located in 2 portions 20 of spray state offsets to rectification state direction.
Under spray state, by making water spray towards spray stream 24 from jet 11, and producing negative pressure in rectification stream 23 side, utilizing this negative pressure to make air be flowed into spray stream 24 from rectification guttation mouth 21 via rectification stream 23, thus generating bubble to be mixed into water.
Thus, when, under spray state, when the position relationship of the jet 11 and vertical hole 124a that are positioned as spray guttation produces skew, then having the misgivings causing that bubble mixed volume during spray guttation reduces.
Therefore, in the present embodiment, possessed the impact preventing the water because spraying from jet 11 and the position relationship of jet 11 and vertical hole 124a produces the position skew prevention unit of skew. Specifically, by above-mentioned guide part 24c, the water sprayed from jet 11 is led in diameter foreign side. That is, lead to the direction different from the direction of rotation (the 1st direction) in the 2nd portion 20 when being switched to 2 state from the 1st state. Thereby, it is possible to make the position relationship that the collision recoil strength occurred when the internal face that the water sprayed from jet 11 and bubble are mixed into water reservoir 24b2 bumps against acts on jet 11 and vertical hole 124a not produce on the direction of skew.
And, in the present embodiment, the connecting portion in the 1st portion 10 and the 2nd portion 20 is provided with and brings the resistance mechanism of resistance (such as to the movement changing respective position relationship, the elastic component such as rubber, spring 50), in order to the position relationship in the 1st portion 10 and the 2nd portion 20 is received in the scope of regulation. The range set of defined is in following permissible range, i.e. be able to ensure that in the permissible range of skew of the jet 11 of bubble mixed volume required during spray guttation and the position relationship of vertical hole 124a. The flow path cross sectional area that the scope of this regulation has vertical hole 124a is more little, becomes more narrow trend.
As it is shown on figure 3, the resistance mechanism of present embodiment possesses the jut 131 of side, the 2nd portion 20 and jut 112a, 112b of side, the 1st portion 10. Be arranged among the frame portion 30 on the end in the 2nd portion 20 in the way of surrounding the periphery in the 1st portion 10, the jut 131 of side, the 2nd portion 20 be formed on on the 1st face that portion 10 is relative. This frame portion 30 could be arranged to interlock when making the 2nd portion 20 rotate and rotate, it is also possible to is the component being attached to the 2nd portion 20, it is also possible to be integrally formed with the 2nd portion 20. Jut 112a, 112b of side, 1st portion 10 is arranged on the position that the jut 131 with side, the 2nd portion 20 can be relative. Jut 112a, 112b are designed to, and when being subject to load from the upper side of apex portion, are then pressed on the central axis direction in the 1st portion 10, when releasing from this load, then utilize elastic force to return to original state.
Under the spray state of Fig. 3 (c), the side of the jut 131 in frame portion 30 abuts with the limiting section 113a in the 1st portion 10, thus on accompanying drawing, the 2nd portion 20 and frame portion 30 become in the counterclockwise direction can not state of rotation again. On the other hand, when the opposite side of jut 131 in frame portion 30 and the jut 112a in the 1st portion 10 abut, then by the elastic force of jut 112a, becoming relative to the 2nd portion 20 and frame portion 30 on accompanying drawing, the movement rotated in the clockwise direction brings the state of resistance. Thereby, it is possible to suppress mobile because causing the 2nd portion 20 to produce when spraying guttation from the flow of water of the water of vertical hole 124a injection such that it is able to prevent the position being located in the 2nd portion 20 of spray state from offseting to rectification state direction.
Under the rectification state of Fig. 3 (a), the side of the jut 131 in frame portion 30 abuts with the limiting section 113b in the 1st portion 10, thus on accompanying drawing, the 2nd portion 20 and frame portion 30 become in the clockwise direction can not state of rotation again. On the other hand, when the opposite side of jut 131 in frame portion 30 and the jut 112b in the 1st portion 10 abut, then by the elastic force of jut 112b, becoming relative to the 2nd portion 20 and frame portion 30 on accompanying drawing, the movement rotated in the counterclockwise direction brings the state of resistance. The state so giving resistance is defined as the 1st resistance unit. Thus, when rectification guttation, it is possible to suppress the movement in the 2nd portion 20 such that it is able to prevent the position being located in the 2nd portion 20 of rectification state from offseting to spray state direction.
Fig. 3 (b), (d) are constituted from rectification state to the state of spray status transition or from spraying the state state to rectification state transition. Under such conditions, abutting to any one of jut 112a, 112b in jut 131 and the 1st portion 10 in frame portion 30, become and do not give the 2nd portion 20 and movement that frame portion 30 rotates is with the state of resistance. Resistance unit less for mobile ratio the 1st resistance unit resistance so rotated for the 2nd portion 20 and frame portion 30 is defined as the 2nd resistance unit. When any one of jut 112a, 112b in jut 131 and the 1st portion 10 in frame portion 30 abuts, then by the elastic force of jut 112a, 112b, become and give the 2nd portion 20 and movement that frame portion 30 rotates is with the state of resistance.
At this, by the resistance mechanism shown in Fig. 3, side, the 1st portion 10 is provided with 2 juts 112a, 112b, thus in the respective use of rectification state and spray state, it is suppressed that the movement in the 2nd portion 20. On the other hand, owing to jut 112a, 112b also give resistance when being switched to rectification state or spray state, the misgivings that operability when causing making switching reduces therefore are had.
Among rectification state and spray state, suppress when guttation the necessity of the movement in the 2nd portion 20 high be when spray state. This is due to when the state of spray, except the permissible range that offset except the position of jet 11 and vertical hole 124a is little, also because from the vertical hole 124a water sprayed, the 2nd portion 20 is in the state of easy movement.
Therefore, resistance mechanism among rectification state and spray state, can also give resistance when being in spray state. Now, it is preferable that resistance mechanism gives resistance in the region switched from rectification state to spray state. Thus, due to when being in spray state, the position relationship being prevented from the 1st portion 10 and the 2nd portion 20 offsets, therefore when spraying guttation, it is possible to suppress the reduction of the bubble mixed volume worried because the position relationship in the 1st portion 10 and the 2nd portion 20 produces skew.
Additionally, resistance mechanism has the 1st region constituting the 1st Resistance Value and constitutes the 2nd region of 2nd Resistance Value less than the 1st resistance unit resistance, and can also using the resistance that gives when being in spray state as the 1st Resistance Value. By reducing the region giving resistance, it is possible to reduce required power when being switched to spray state such that it is able to suppress the reduction of operability. Now, it is preferable that resistance mechanism is closer to spray state and then gives more big resistance, and gradually increases resistance. Thus, when being switched to spray state, owing to the collision sense produced because of resistance can be made to become soft, therefore, it is possible to prevent user from thinking by mistake, operation completes, and can suppress the reduction of operability. In addition, when leaving from spray state, owing to the skew in the 1st portion 10 and the position relationship in the 2nd portion 20 can be received in the scope of regulation, therefore, it is possible to suppress the reduction of the bubble mixed volume worried because the position relationship in the 1st portion 10 and the 2nd portion 20 produces skew. With reference to Fig. 4, this variation is specifically described.
Fig. 4 indicates that the figure of the variation of the resistance mechanism shown in Fig. 3. Resistance mechanism in this variation possesses the protrusion 231 of side, the 2nd portion 20 and the jut 212 of side, the 1st portion 10. The protrusion 231 of side, the 2nd portion 20 is formed among frame portion 30, and on the 1st face that portion 10 is relative. On protrusion 231, the end of length direction is formed with limiting section 231a, 231b. The limiting section 231a of side is formed substantially vertical crown line, and the limiting section 231b of opposite side then is formed from crown line end to tilt and be formed.
The jut 212 of side, the 1st portion 10 is arranged on the position that the protrusion 231 with side, the 2nd portion 20 can be relative. Jut 212 is designed to, and is then pressed on the central axis direction in the 1st portion 10 when being subject to load from the upper side of apex portion, is then returned to original state by elastic force when releasing from this load.
At Fig. 4 (c) under spray state, the limiting section 213a in 1 portion 10 of limiting section 231a and the in frame portion 30 abuts, thus on accompanying drawing, the 2nd portion 20 and frame portion 30 become in the counterclockwise direction can not state of rotation again. On the other hand, when the jut 212 in 1 portion 10 of limiting section 231b and the in frame portion 30 abuts, then by the elastic force of jut 212, becoming relative to the 2nd portion 20 and frame portion 30 on accompanying drawing, the movement rotated in the clockwise direction brings the state of resistance.
Thereby, it is possible to suppress because of when spraying guttation from the flow of water of water of vertical hole 124a injection, and the 2nd portion 20 produces mobile such that it is able to prevent the position being positioned the 2nd portion 20 of spray state to the skew of rectification state direction.
Under the rectification state of Fig. 4 (a), the limiting section 213b in 1 portion 10 of limiting section 231b and the in frame portion 30 abuts, thus on accompanying drawing, the 2nd portion 20 and frame portion 30 become in the clockwise direction can not state of rotation again. On the other hand, owing to the jut 212 in the 1st portion 10 maintains the state of the protrusion 231 being pressed into frame portion 30, the movement in the 2nd portion 20 and frame portion 30 is therefore allowed.
Fig. 4 (b), (d) are constituted from rectification state to the state of spray status transition or from spraying the state state to rectification state transition. Under such conditions, owing to the jut 212 in the 1st portion 10 maintains the state of the protrusion 231 being pressed into frame portion 30, the movement in the 2nd portion 20 and frame portion 30 is therefore allowed.
Fig. 5 is the guttation state chart with the relation of operation resistance of the resistance mechanism being illustrated in variation unlike those described above. As it is shown in figure 5, resistance mechanism is among the zone line of rectification state and spray state, from being switched to close to spray state in the region R of spray state, is constituting the movement to the 2nd portion 20 and frame portion 30 rotation and bringing the state of resistance. Additionally, the resistance then given in the R of region closer to spray state becomes more big.
The summary using the effect of Fig. 6 and Fig. 7 guttation mouth cap 1 to being made up of above-mentioned composition illustrates. Fig. 6 (a) and Fig. 7 (a) indicates that as the 1st state and rectification state, and makes water W flow to rectification stream 23, and makes to be mixed into the figure of the guttation state of water W from the air Air spraying stream 24. Additionally, indicate that and namely spray state with figure (b) as the 2nd state, make water W flow to spray stream 24, and make the air Air of self-rectifying stream 23 be mixed into the figure of guttation state of water W.
As shown in Fig. 6 (a) and Fig. 7 (a), under rectification state, when the multiple jet 11 formed from the periphery in the 1st portion 10 is for feedwater W, then water W flows down on injection direction, it is flowed into rectification stream 23, and bumps against with stream wall 23a. Water W or flick from stream wall 23a, or flow down along stream wall 23a, and it is directed into rectification guttation mouth 21 side. It addition, Fig. 3 (a) illustrates the jet 11 of this rectification state and the state of the relation in the 2nd portion 20.
Now, spray guttation mouth 22 plays a role as air induction port, and spray stream 24 plays a role as air flow circuit. Namely, as shown in Fig. 6 (a) and Fig. 7 (a), by spraying water from jet 11 towards rectification stream 23, and in spray stream 24, produce negative pressure, thus air Air flows into towards rectification stream 23 from spray guttation mouth 22 via spray stream 24. Air Air is mixed into water reservoir 24b2 from bubble and is flowed in rectification stream 23 via vertical hole 124a, and is rolled into the current of water W with cystose.
In rectification guttation mouth 21, owing to water is temporarily detained on screens 21a, therefore form gas-liquid interface Ia. Protrude into this gas-liquid interface Ia by water W, and form foamed air Air and be mixed into it, and generate bubble and be mixed into water Bw. Bubble is mixed into water Bw and flows through screens 21a and spue successively from rectification guttation mouth 21.
On the other hand, as shown in Fig. 6 (b) and Fig. 7 (b), under spray state, when supplying feedwater W from the jet 11 of multiple formation on the periphery in the 1st portion 10, then water W flows down on injection direction, it is flowed into the vertical hole 124a of spray stream 24, and the bubble being directed under just with original state is mixed into water reservoir 24b2. It addition, Fig. 3 (c) illustrates the state of the relation in the jet 11 under this spray state and the 2nd portion 20.
Now, rectification guttation mouth 21 plays a role as air induction port, and rectification stream 23 then plays a role as air flow circuit. That is, as shown in Fig. 6 (b), by spraying water from jet 11 towards spray stream 24, producing negative pressure on rectification stream 23 side, air Air flows into towards spray stream 24 from rectification guttation mouth 21 via rectification stream 23. Air Air flows through rectification stream 23 from screens 21a, and is flowed into the vertical hole 124a spraying stream 24, and is rolled into the current of water W with cystose.
In spray stream 24, due to the flow path resistance because spraying guttation mouth 22, and water is mixed in water reservoir 24b2 at bubble and is temporarily detained, and therefore forms gas-liquid interface Ib. Protrude into this gas-liquid interface Ib by water W, and form foamed air Air and be mixed into it, and generate bubble and be mixed into water Bw. Bubble is mixed into water Bw and flows through spray guttation mouth 22 and spue to outside.
In addition, owing to being mixed in water reservoir 24b2 at bubble, by above-mentioned guide part 24c, the water sprayed from jet 11 is upwards led in diameter foreign side, therefore, it is possible to make the position relationship that the collision recoil strength that the internal face that the water from jet 11 injection and bubble are mixed into water reservoir 24b2 occurs when bumping against acts on jet 11 and vertical hole 124a not produce the direction of skew.
The guttation mouth cap 1 of present embodiment is following device, namely, by making the 2nd portion 20 rotate relative to the 1st portion 10, or make it from the spray state shown in Fig. 3 (a) to the rectification state transition shown in Fig. 3 (c), or make it from the rectification state shown in Fig. 3 (c) to the spray status transition shown in Fig. 3 (a), thus realize rectification guttation and the device of spray guttation.
As mentioned above, according to the embodiment of the present invention, by changing the relative position relationship in the 1st portion 10 and the 2nd portion 20, allow hand over the rectification state making water flow from jet 11 to rectification stream 23 and making from the inclusion of air to this water spraying stream 24, and make water flow from jet 11 to spray stream 24 and make the inclusion of air spray state to this water of self-rectifying stream 23, and by the flow path cross sectional area of the upstream side of spray stream 24 is formed as less than the flow path cross sectional area in downstream, it is prevented from the adverse current in the spray stream 24 when spraying guttation, and by arranging position skew prevention unit (guide part 24c and resistance mechanism), bring resistance can to the movement of the position relationship changing the 1st portion 10 and the 2nd portion 20, the position relationship in the 1st portion 10 and the 2nd portion 20 is received in the scope of regulation.
Thus, due to can by guttation time the 1st portion 10 and the skew of position relationship in the 2nd portion 20 be received in the scope of regulation, therefore, it is possible to suppress the reduction of the bubble mixed volume worried because the position relationship in the 1st portion 10 and the 2nd portion 20 produces skew.
It follows that the guttation mouth cap 1 involved by the embodiment of the 3rd of the present invention the is illustrated. Although offseting prevention unit as position, and the flowing path section of vertical hole (adverse current preventing portion) 324a is formed as different on this aspect of flat pattern in the way of becoming length direction by the direction of rotation (the 1st direction) in the 2nd portion 20 in time being switched to 2 state from the 1st state, but the composition for other is then identical with above-mentioned embodiment. Therefore, the explanation to the composition common with above-mentioned embodiment omitted below.
As shown in Figure 8, the direction of rotation (the 1st direction) in the flowing path section shape of the vertical hole 324a of present embodiment the 2nd portion 20 in time being switched to 2 state from the 1st state is formed flat pattern in the way of becoming length direction.
And, the width being formed the orthogonal width of the length direction of the vertical hole 324a of flat pattern with flowing path section shape is configured to substantially uniform width.
Fig. 9 indicates that the sectional view of the summary of the effect of the spray stream of guttation mouth cap.
As shown in Fig. 9 (a) and Fig. 9 (b), time in the centre line L that jet 11 is configured in vertical hole 324a, water from jet 11 becomes the central-injection to vertical hole 324a such that it is able to discharge bubble is mixed into water, and does not reduce bubble mixed volume.
In addition, as shown in Fig. 9 (c) and Fig. 9 (d), even if when jet 11 offsets from the centre line L of vertical hole a, owing to the flowing path section of vertical hole 324a is shaped so as to flat pattern, therefore it also is able to easily maintain the state that whole injection water passes through in the inside of vertical hole 324a.
And, by the flowing path section of vertical hole 324a is shortened (reduction flow path cross sectional area) on the direction orthogonal with the direction of rotation (the 1st direction) in the 2nd portion 20 when being switched to 2 state from the 1st state, it is also possible to prevent the bubble being mixed in water reservoir 24b2 to accumulate at bubble to be mixed into water to air introduction part 602 side adverse current.
It follows that the guttation mouth cap 1 involved by the embodiment of the 4th of the present invention the is illustrated. Although offseting prevention unit as position, and make the flow path cross sectional area of vertical hole (adverse current preventing portion) 424a become different from upstream side 425a towards this aspect of the downstream 425b shape diminished, but the composition for other is then identical with above-mentioned embodiment. Therefore, the explanation to the composition common with above-mentioned embodiment omitted below.
As shown in Figure 10, the flowing path section of the vertical hole 424a in present embodiment is shaped so as to the inverted cone-shaped that gradually diminishes from upstream side towards downstream.
According to this composition, even if when just in case because of the impact of water spray from jet 11, the position relationship of jet 11 and vertical hole (adverse current preventing portion) 424a somewhat produces skew, owing to the inlet opens 426 in vertical hole is big, therefore it also is able to easily maintain the state that whole injection water passes through in the inside of vertical hole 424a. Additionally, because the flow path cross sectional area of the downstream portion of vertical hole 424a is little, so also being able to prevent the bubble being mixed in water reservoir 24b2 to accumulate at bubble to be mixed into water to air introduction part 602 side adverse current. In addition, owing to the flow path cross sectional area of vertical hole 424a to be formed as reduce from upstream side 425a towards downstream 425b, even if therefore when the inwall of the downstream portion of a part with vertical hole 424a of spraying water somewhat produces to interfere, water owing to bumping against because spraying the flow of water of water is pressed into downstream, also therefore is able to prevent injection water to air introduction part 602 side adverse current.
Above by reference to concrete example, embodiments of the invention are illustrated. But, the invention is not limited in above-mentioned concrete example. For example, it is also possible to by making the 2nd portion 20 slide relative to the 1st portion 10, switchably to constitute as mentioned above spray guttation and rectification guttation.
