Description

Intuitively operated segmented water-saving spool

The present invention relates to a faucet spool; in particular, an innovative spool structure type revealer capable of achieving an intuitively operated segmented water saving function.

According to the internal structure design of the faucet, the purpose of controlling the water flow opening and closing and the flow switching state is mainly achieved through the setting of a valve core, and the structural type of the valve core is different according to the functional type of the faucet. There are differences, such as single temperature faucet, double temperature faucet, split faucet, etc., the structure of the valve core has different differences.

The faucet valve core to be discussed in this creation is specifically for the valve core structure used in the single-temperature faucet. The valve core structure of the single-temperature faucet is mainly based on a rotating valve piece on a fixed valve plate. The rotation angle changes to control the water flow opening and closing and the size state. If the faucet switch is in the range of 180 degrees of the stroke range, the rotating valve piece and the fixed valve piece are usually provided with a half-moon shaped water hole, so As the angle of rotation of the rotating valve plate on the fixed valve plate changes, a state of full opening, full closing or different cross-section between the two half-moon shaped water-permeable holes is formed.

In recent years, due to the rapid changes in climate, the factors that make water resources scarce, so that the relevant units continue to advocate the concepts of “water saving” and “saving water”, and water saving is the faucet that is closely related to the daily life of the public. However, it has become one of the focuses of attention; however, in terms of the general habit of the general public to operate the faucet, it is actually difficult to achieve the purpose of water saving, which mainly involves the design of the conventional faucet valve core structure described in the previous paragraph; In other words, because of the aforementioned two-half-moon shape of the rotating valve piece and the fixed valve piece When the degree of communication between the water holes exceeds about 30% (that is, the faucet switch rotates by more than 30 degrees), since the cross-sectional area of the flow path has reached a sufficient flow amount, the water output of the faucet is actually already at the time of full opening. The difference in water volume is not large. However, when the general public operates the faucet switch, the instantaneous rotation angle will easily exceed 30 degrees. Especially the wrench type is more likely to exceed this angle range. Impossible, and it is quite difficult to change the inherent habits that people have developed over a long period of time; if they can change the design of the sump structure itself to solve this problem, instead The possibility is relatively high, and it is also a technical issue worthy of consideration by the relevant industry.

Therefore, in view of the problems existing in the above-mentioned conventional faucet valve core structure, how to develop an innovative structure that can be more ideal and practical, and the relevant industry should further consider the goal and direction of breakthrough.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation.

Please refer to Figures 1 to 5 for a preferred embodiment of the intuitively operated segmented water-saving spool. However, these embodiments are for illustrative purposes only and are not limited by this structure in patent applications. The spool A includes the following components: The valve housing 10 is in the form of a hollow casing, and includes a through hole 11 formed in one of the reduced diameters at the upper end of the valve casing 10, and a lower port 12 disposed at the lower end of the valve casing 10, and is formed inside the valve casing 10. An accommodating space 13 and a water flow outlet hole 14 disposed on the circumferential side of the valve casing 10 adjacent to the lower port 12, the water flow outlet hole 14 is in communication with the accommodating space 13; a control valve stem 20 is a rotatable vertical direction The rod body type includes a top end receiving portion 21 and a bottom end driving piece 22, wherein the top end receiving portion 21 extends upwardly and protrudes above the upper opening 11 of the valve casing 10, and the bottom end driving piece 22 is directed to The lower extension is placed in the accommodating space 13 of the valve casing 10; a swash plate 30 is slidably coupled to the bottom end of the control valve stem 20 to drive the sheet 22; a linkage 40 is in a movable state. Below the turret disk 30, the locating block 40 includes a through-flow recess 41 corresponding to the water flow outlet hole 14 provided on the circumferential side of the valve casing 10. A fixed valve plate 50 is a ceramic plate body and is in a combined state. The valve housing 10 is near the lower port 12, and the fixed valve piece 50 has a water inlet hole 51 in an upright through-type; a rotating valve piece 60, A ceramic sheet body is assembled under the linkage housing 40 and stacked above the fixed valve plate 50. The rotary valve sheet 60 has a water-through hole 61 in an up-through shape. The water-passing hole 61 The upper portion is in communication with the through-hole recess 41 of the linkage 40; the rotating valve piece 60 is rotatable on the fixed valve plate 50 to change the alignment state between the water-passing hole 61 and the water inlet hole 51; The reducing block 70 is formed by the interlocking seat 40 having a side portion of the through-hole recess 41 projecting downwardly into a partial area of the water-passing hole 61 of the rotating valve piece 60. The flow path reducing block 70 can block the wearing. The partial flow path area of the water hole 61 is such that a flat space is left between one side of the flow path reducing block 70 and the hole wall of the water penetrating hole 61 (as shown by W1 in FIG. 4); The through-flow passage 80 is reduced by the flat passage between the one side of the block 70 and the hole wall of the water-passing hole 61 (as shown in FIG. 4). The narrow flow path space type of the opposite structure is shown by W1. The flow reduction passage 80 communicates with the water inlet hole 51 of the fixed valve piece 50 and the water flow outlet hole 14 of the valve casing 10 (see FIG. 5). Shown).

With the above structural composition design, when the rotating valve piece 60 is rotated between the water-permeating hole 61 and the water inlet hole 51 on the fixed valve piece 50, please follow the steps 7 and 9 and first pass through a section. Only the water-reducing section of the flow-reducing flow passage 80 that provides a weaker outlet flow rate (as indicated by an arrow L1) allows the user to use the water-saving mode at the initial stage of opening the water supply, which is most directly adopted by the user. The operational sensation (including the visual and the feeling of flipping or turning the faucet switch) can be achieved without having to deliberately fine-tune the control to achieve the intuitively operated segmental water saving function.

As shown in the second and third figures, the water inlet hole 51 of the fixed valve piece 50 and the water penetration hole 61 of the rotating valve piece 60 may be semi-circular hole patterns, and the flow path reduction block 70 is occupied. The through hole 61 has a block form of a ratio of one-ninth to two-thirds of the area. (Note: the figure is expressed in a quarter area ratio)

As shown in FIG. 6, the accommodating space 13 of the valve housing 10 corresponds to the height position of the bottom end of the control valve rod 20, and the limiting rib 15 can be disposed to resist the bottom end of the driving piece 22 to limit Control the maximum angle of rotation of the valve stem 20 (such as 180 degrees or 90 degrees, etc.).

As shown in the figures of Figs. 7, 9, and 11, wherein the rotating valve piece 60 is rotated on the fixed valve piece 50, the maximum angle of the action range between the water-passing hole 61 and the water inlet hole 51 from the closing to the set maximum communication state is as follows. It can be set to 180 degrees; the water-saving section which provides the weak water discharge flow rate by the flow reducing passage 80 is rotated when the rotating valve piece 60 is rotated on the fixed valve piece 50 to start the communication between the water-passing hole 61 and the water inlet hole 51. When it is set to 0 degree, the maximum angle of the actuation stroke range is between 20 degrees and 120 degrees; in this example, the part of the rotation angle range set to 180 degrees can be accommodated by the valve casing 10 13 is to achieve the distribution pattern of the limit retaining edge 15, which can be compared with the sixth, eighth, and tenth figures. The limit retaining edge 15 of this example is distributed in a half arc length. Blanking The shape of the bump on the inner side of the gap 13 can thereby limit the rotation angle of the bottom end of the control valve stem 20 to a range of 180 degrees; the flow path change state of this example is as shown in FIG. When the control valve stem 20 is rotated to the set water stop mode, the water passage hole 61 constituting the rotary valve piece 60 and the water inlet hole 51 of the fixed valve piece 50 are completely displaced (as shown in FIG. 7). At this time, the water flow outlet hole 14 on the circumferential side of the valve casing 10 is in a waterless flow-extracting state; then, as shown in FIG. 8, when the control valve stem 20 is rotated to the set water-saving section position, since the self-fixing valve plate 50 The water flow introduced by the water inlet hole 51 can only pass through the narrow flow-reducing flow passage 80 which is provided between the side of the flow path reducing block 70 and the hole wall of the water-passing hole 61 (for example, the arrow of FIG. 9 No. L2), so the water flow outlet hole 14 will only exhibit a weak water flow state (as indicated by arrow L3 in Fig. 9); then, as shown in Fig. 10, when the control valve stem 20 is rotated to the set In the full water discharge mode, the bottom end driving piece 22 is restrained by the limiting retaining edge 15 and is limited, and at this time, the water passing hole 61 and the fixed valve piece 50 of the rotating valve piece 60 are formed. The water inlet holes 51 are in a state of full hole alignment (as shown in FIG. 11), so that the water flow introduced from the water inlet hole 51 of the fixed valve piece 50 can simultaneously reduce the flow passage 80 and the rotary valve piece from the flow rate. The unblocked area of the water permeable aperture 61 of 60 passes (as indicated by arrow L4), thereby causing the water flow outlet aperture 14 to reach a large outlet flow state (as indicated by arrow L5).

As shown in Figs. 13 and 15, the rotation angle of the rotating valve piece 60 on the fixed valve piece 50 between the water-passing hole 61 and the water inlet hole 51 from the closing to the set maximum communication state can also be set to 90. The water-saving section that provides the weak water discharge flow rate by the flow reducing passage 80 is set to 0 when the rotating valve piece 60 is rotated on the fixed valve piece 50 to cause the communication between the water-passing hole 61 and the water inlet hole 51 to start communication. The maximum angle of the actuation stroke range is between 20 degrees and 90 degrees. In this example, the portion of the rotation angle range set to 90 degrees can be set by the valve housing 10 housing space 13. The distribution pattern of the limit retaining edge 15B is achieved. This portion can be compared with the 12th and 14th drawings. The limit retaining edge 15B of this example is distributed in the accommodating space 13 by two quarters of an arc length. Relative to the convex shape on the two sides, thereby limiting the rotation of the bottom end of the control valve stem 20 to rotate the sheet 22 The angle is in the range of 90 degrees; in this example, if the maximum angle of the operating stroke range of the water saving section is also set to 90 degrees, as shown in Fig. 15, even if the rotating valve piece 60 is on the fixed valve piece 50 When it is rotated to the maximum angle, it is still only in the state of weak water flow, and there is no water supply mode with large water volume. This embodiment can be applied to some public places to achieve the purpose of normal water saving.

As shown in FIG. 2, the tilting disk 30 can include a driven edge portion 32 that can be driven by the bottom end driving piece 22. The tilting disk 30 and the connecting base 40 are provided with a card that can be interlocked with each other. The bottom linking block 33 and the driven groove 42; and the two sides of the rotating seat 40 and the rotating valve piece 60 are provided with two claws 43 and two engaging grooves 62 which can be interlocked with each other.

As shown in the second and fifth figures, the rocking disk 30 can include a water stop ring 31 on the circumferential side of the casing, and the water stop ring 31 is in close contact with the peripheral wall of the accommodating space 13 of the valve casing 10. Therefore, the tilting disk 30 has the function of waterproofing and leaking out, but the water stopping function is not limited to adopting such a type, for example, the control valve stem 20 and the valve casing 10 can also be used. The type of the water stop ring is set between the upper piers 11 (note: the illustration is omitted from the drawing).

As shown in FIG. 16 , another embodiment of the flow path reducing block 70B of the connecting frame 40 is provided. The maximum angle of the operating range of the flow path reducing block 70B of this embodiment (ie, X) is It is also possible to implement a mode that is set to an angle of less than 90 degrees.

Efficacy description:

The "intuitively operated segmented water-saving valve core" disclosed in the present invention mainly consists of a portion of the water-passing hole of the rotating valve plate which protrudes downward from the side of the connecting seat to form a flow-reducing block capable of blocking the wearing.

The user almost does not need to change the inherent faucet operating habits, because the user created the valve core structure, the user just Within a certain angle range of opening the faucet switch (such as within 90 degrees), it will be set to a smaller outlet flow state (ie, water saving mode). If the user feels that the water flow does not meet the demand, the faucet switch must be further turned to the maximum. The angle (such as 180 degrees) will truly reach the state of large water flow. Therefore, the user can easily achieve the purpose of water saving through intuitive control, which is practical and progressive and user-friendly. On the other hand, the “intuitive control-type segmental water-saving valve core” disclosed in this creation shows that the water-saving function can be achieved only by the structural type innovation of the linkage seat, and the majority of the valve core. The components can follow the existing types and specifications, which can save the manufacturing cost of the innovative development products for the industry, and achieve better industrial economic benefits and be easier to implement.

The disclosures of the above embodiments are specifically intended to illustrate the present invention, and although the descriptions are made by specific terms, the scope of patents of the present invention cannot be limited thereto; those skilled in the art can understand the spirit of the creation. The principles are changed and modified to achieve an equivalent purpose, and such changes and modifications are to be included in the scope defined by the scope of the patent application as described later.
