Detailed Description
The invention solves the defects that the flow regulation is inaccurate and the regulation characteristic is not suitable for daily use in the prior art, and provides a multifunctional valve core which is provided with a valve shell for convenient assembly and protection, wherein a flow regulating component is arranged in the valve shell, and further, a water stopping component is also arranged in the valve shell and is respectively used for regulating the flow and switching the water flowing and stopping state of the valve core.
In order to realize the rotary flow regulating function, the flow regulating assembly comprises a rotary actuating piece, a bearing seat and a fixed seat, wherein the bearing seat and the fixed seat are respectively provided with a first water passing port and a second water passing port, and the two water passing ports are matched to form a first water flow channel in the assembled bearing seat and the fixed seat. Generally, the through-flow cross section of the first water flow channel can be changed at the throttling position by changing the matching mode of the two water passing ports. Therefore, in order to change the matching mode of the water passing ports, the rotary actuating piece is arranged in linkage with the bearing seat so as to drive the rotary actuating piece to rotate relative to the fixed seat, and further the overlapped through flow section of the first water passing port and the second water passing port is controlled to be changed.
It is a primary object of the present invention to provide a user with a small-to-large increase in flow rate change level as the adjustment travel changes, i.e., the rate of flow rate change increases, preferably linearly, with the adjustment travel to achieve an easily controllable response. Under the above requirements, one of the first water passing port and the second water passing port has an eccentric characteristic section, the other has a linear characteristic section, and the change rate of the through-flow section along the rotation stroke is increased gradually.
Understandably, the eccentric characteristic section mainly has the following two cases: (1) When water flows through the water passing port, the cross section area of the water flow changes monotonically along the water flow direction; (2) When water flows through the water passing opening, the cross section of the water passing opening along the water flow direction is constant, but the cross section of the water passing opening perpendicular to the water flow direction is a non-centrosymmetric cross section, and the change rate of the cross section along the rotation travel direction is monotonously changed. On the contrary, if a water passing port is in the water flow, the cross section of the water passing port along the water flow direction is constant, and the cross section of the water passing port perpendicular to the water flow direction is a central symmetrical cross section, or the water passing port does not have the characteristic of monotonically changing the cross section along the rotation travel direction, the water passing port is defined to have a linear characteristic cross section.
Thus, the two water passing ports form a throttling position at the matching position, and the throttling characteristic of the throttling position is determined by the changing characteristic of the through flow section of the two water passing ports. When the two water passing ports respectively have the characteristics, the forward overlapping relation of the two water passing ports is changed, so that the flow area of the first water flow channel at the throttling position is monotonously changed along with the progress of the regulating stroke. On the other hand, since the flow of the water always has the characteristic of filling the whole orifice, further, the main purpose of the invention can be achieved by adjusting the water inflow path or direction of the water flow or adjusting the assembly relation of the two water passing ports to form a first water flow channel which enables the flow area at the throttling position to be increased along with the adjustment stroke. Therefore, a user can accurately adjust the low flow section at the initial section of the adjusting stroke in a small range, and the high flow section at the rear section of the adjusting stroke can quickly respond and adjust the flow in a large range, so that the flow adjusting device meets the operation characteristics of the user flow adjustment.
In addition, in order to realize the water-through state switching of the valve core, a second water flow channel is further arranged in the bearing seat, and the first water flow channel after the completion of flow adjustment is connected with the second water flow channel through a third water flow port arranged on the bearing seat. And the water stopping assembly comprises a water stopping actuating piece and a sealing piece, wherein the sealing piece is driven by the water stopping actuating piece to selectively seal the third water passing port so as to communicate or isolate the first water flow channel and the second water flow channel. When the first water flow channel and the second water flow channel are communicated, the water flow function is realized, otherwise, when the first water flow channel and the second water flow channel are separated, the valve core is switched to a water stop state.
Under the above configuration, the valve core can realize that the first water circulation, namely the water outlet flow of the valve core, is regulated by operating the water stop actuating element to switch the water stop state of the valve core and rotating the rotary actuating element, and the two are independently operated and do not interfere with each other.
The invention is further described below with reference to the drawings and examples. It should be noted that, the following embodiments all adopt the main flow operation mode of pressing members to realize pressing switching through water, but adopt the cooperation of other existing operation members and transmission members, and combine the above-mentioned structures of the present invention to form the valve core, which is a simple replacement within the spirit of the present invention.
Example 1
Referring first to fig. 1-4, the multifunctional valve core 1 of the present embodiment includes a valve housing 10, in which a flow regulating assembly 20 and a water stopping assembly 30 are disposed.
The flow regulating assembly 20 comprises a rotary actuating member 21, a receiving seat 22 and a fixing seat 23, wherein the receiving seat and the fixing seat are respectively provided with a first water passing port 221 and a second water passing port 231, and the two water passing ports are matched to form a first water flow channel 24 with variable through flow sectional area in the assembled receiving seat and fixing seat. The rotary actuating member 21 is arranged in linkage with the receiving seat 22 to drive the rotary actuating member to rotate relative to the fixed seat 23, so as to control the overlapped through-flow section of the first water passing port and the second water passing port to be changed. In this embodiment, the rotary actuator 21 is connected to the socket 22 by a snap and a claw.
Meanwhile, the socket further has a second water flow channel 25 therein, and the first water flow channel 24 and the second water flow channel 25 are connected through a third water passing port 222 provided on the socket 22. The water stop assembly 30 includes a water stop actuating member 31 and a sealing member 32 driven by the water stop actuating member to selectively seal the third water passing port 222, thereby communicating or blocking the first water flow passage 24 and the second water flow passage 25.
Referring to fig. 5-9, in a specific structure, the receiving seat 22 and the fixing seat 23 are all integrated. The upper end of the fixing seat 23 is provided with a protruding column 232, and the sidewall of the protruding column is hollowed with a through hole, and the through hole is the second water passing hole 231. The through-hole 231 has a constant cross-sectional area along the inflow direction of the water flow, and a cross-section perpendicular to the water flow direction is a cross-section with central symmetry, and does not have the characteristic of monotonically changing the rate of change of the cross-sectional area along the rotation travel direction, so that it always has the same rate of change of the cross-sectional area along the rotation direction of the socket 22, thereby defining a cross-section with linear characteristics.
Correspondingly, the lower end of the receiving seat 22 is provided with a flow regulating cavity 223, a section of arc transition wall 224 is arranged in the flow regulating cavity, two ends of the arc transition wall are respectively connected with a large revolving wall and a small revolving wall, the inner edge and the outer edge of the transition wall 224 are two sections of arcs with different curvature radii, and the curvature radii of the two sections of arcs are the radii of the large revolving wall and the small revolving wall.
The boss 232 is inserted into the flow regulating cavity 223, and a gap is formed between the outer wall of the boss and the transition wall 224, and the gap is the first water passing hole 221. From the geometric perspective of the notch 221, if the water flow in the flow regulating cavity 223 approximately flows along the peripheral edge of the transition wall 224, the through-flow cross-sectional area of the first water passing port 221 along the water flow direction increases monotonically; if the water flow axially flows in the flow regulating cavity 223, the through-flow cross section of the first water passing port 221 perpendicular to the water flow direction is crescent, is a non-centrosymmetric cross section, and monotonically changes in the change rate of the cross section along the rotation travel direction. Thus, the first water passing hole 221 is defined to have an eccentric characteristic section.
The relative rotation direction of the bearing seat and the fixing seat is adjusted, so that the change rate of the through flow cross section area of the first water flow channel 24 along the rotation stroke is increased.
In fig. 10-13, two typical states of the valve spool 1 are shown, namely a low flow state and a high flow state, respectively. It can be seen that in fig. 10 and the corresponding fig. 12, the degree of overlap of the first water passing port 221 and the second water passing port 231 is only a small part overlapping; in fig. 11 and fig. 13, the first water passing hole 221 and the second water passing hole 231 are mostly overlapped due to the relative rotation of the socket 22 and the fixing base 23. Since the transition wall 224 has the above characteristics, the flow rate change rate at the position shown in fig. 11 and 13 is significantly larger than that at the position corresponding to fig. 10 and 12.
In addition, the present embodiment adopts two schemes to enhance the stability of the valve core during operation, so as to prevent the defects that the bearing seat 22 and the fixing seat 23 deviate from the axis of the valve core possibly caused by the larger water pressure due to the eccentric characteristic of one of the first water passing port and the second water passing port, the stability is insufficient, and noise is easily generated.
In a first embodiment: the top end of the boss 232 is downwardly formed with a positioning slot 233, and a positioning post 225 is downwardly protruded from the upper wall of the flow regulating cavity 223, and is reversely inserted into the positioning slot when the boss is inserted into the flow regulating cavity, so as to be more stable in the axial direction, as shown in fig. 3-4 and fig. 10-11.
In a second embodiment: the large rotation wall of the flow regulating cavity 223 is provided with a plurality of positioning ribs in a protruding manner along the radial direction, and the positioning ribs are matched with the outer wall of the convex column 232 so as to make the convex column more stable in the axial direction.
In a specific structure, the fourth water passing port 226 and the fifth water passing port 234 are further respectively provided on the receiving seat 22 and the fixing seat 23. The fourth water passing port 226 is an end of the second water flow channel 25 away from the third water passing port 222, and the fifth water passing port 234 is an end of the first water flow channel 24 away from the second water passing port 231. In this embodiment, the fourth water passing port 226 is located at a side of the receiving seat 22, and the fifth water passing port 234 is located at a bottom of the fixing seat 23.
For the water inlet and outlet direction of the valve core 1, the present embodiment adopts a mode that the fourth water passing port and the fifth water passing port are the water inlet and the water outlet of the valve core respectively, and similarly, the present embodiment also adopts a mode that the fifth water passing port and the fourth water passing port are the water inlet and the water outlet of the valve core respectively. Because the sealing piece or other components with the non-return function are not arranged between the first water flow channel 24 and the second water flow channel 25, the water inlet and outlet modes can be simply switched between the bottom inlet and the side outlet or the side inlet and the bottom outlet, and the corresponding shower equipment flow channel is only designed according to the water inlet parameters, so that the valve core has wide adaptability.
Further, referring to fig. 3-4 and fig. 6 in particular, in this embodiment, a revolving wall 227 is disposed at an end of the receiving seat 22 near the water stop assembly 30, and an opening at an upper end of the revolving wall forms the third water passing port 222. Specifically, the water stop assembly 30 further includes a pressure cover 33 and a propping member 34, and the sealing member 32 is a sealing cup. The pressure cover 33 and the sealing cup 32 are both installed on the receiving seat 22, and the sealing cup covers the third water passing port 222. The pressure cover and the sealing leather cup surround to form a pressure cavity 35, the sealing leather cup is provided with a pressure relief hole and a drainage hole, and the drainage hole is always communicated with the first water flow channel 24 and the pressure cavity 35.
The propping piece 34 is driven by the water stop actuating piece 31, and the tail end of the propping piece is provided with a sealing ring which is in sealing fit with the pressure relief hole, and the pressure relief hole is selectively propped by the propping piece, so that the pressure cavity 35 and the second water flow channel 25 are communicated or blocked.
When the pressure release hole is propped against the propping piece to seal the pressure release hole, water is guided by the first water flow channel 24 through the drainage hole, and fills the pressure cavity 35, and the upper and lower surfaces of the sealing cup 32 are pressed on the rotary wall 227 tightly due to the same water pressure, so that the third water passing port 222 cuts off the connection between the first water flow channel 24 and the second water flow channel 25, and the valve core is in a water stopping state, as shown in fig. 4.
When the pressure release hole is not propped against the propping piece to seal the pressure release hole, water in the pressure cavity 35 flows from the pressure release hole to the second water flow channel 25 to realize pressure release, the water pressures borne by the upper surface and the lower surface of the sealing leather cup 32 are different, the pressure difference between the upper end and the lower end is formed by the lower end, the sealing leather cup 32 is propped up by water flow to leave the rotary wall 227, so that the third water passing port 222 is communicated with the first water flow channel 24 and the second water flow channel 25, and the valve core is in a water passing state, as shown in fig. 3.
Other advantages and specific structures of the sealing member 32 used in the present embodiment are disclosed in the patent document with publication number CN107620814a, and are not described in detail below.
In a preferred embodiment, the end of the propping piece 34 that cooperates with the pressure relief hole protrudes an extension that is inserted into the pressure relief hole. And an overflow gap is reserved between the outer wall of the extension part and the wall of the pressure relief hole, so that when the propping piece is matched with the pressure relief hole, the wall of the pressure relief hole moves relative to the wall of the pressure relief hole and impurities in the hole are removed.
Further, the water stop actuating member 31 of the present embodiment is a pressing button, and the water stop assembly further includes a transmission member 36 and a reset member 37. The rotary actuating member 21 is a rotary sleeve, and the transmission member 36, the propping member 34, the pressure cover 33, the resetting member 37 and the sealing member 32 of the water stop assembly 30 are all installed in the installation space enclosed by the rotary sleeve and the bearing seat.
The pressing button 31, the transmission member 36, and the propping member 34 are disposed in a linkage manner, and pressing the pressing button 31 causes the propping member 34 to rest at a high position or a low position, so as to prop against the selectively propping sealing member 32, so as to communicate or block the pressure chamber 33 with the second water flow channel 25, and further control whether the first water flow channel 24 and the second water flow channel 25 are communicated.
The transmission member 36 is an automatic pen-type pressing mechanism commonly used in the art, and comprises a static ratchet, a dynamic ratchet and a first spring, and the reset member is a second spring arranged between the pressure cover and the static ratchet.

One end of the second spring is propped against the top wall of the inner cavity of the movable ratchet wheel, and the other end of the second spring is propped against the upper end of the propping piece; the movable ratchet of the movable ratchet is driven to rotate by pressing the pressing button and the static ratchet, so that the movable ratchet of the movable ratchet is switched between the high-position stroke and the low-position stroke back and forth in the step surface of the resisting part of the rotary sleeve and the vertical chute.
For the automatic pen-type pressing mechanism, refer to the structure specifically described in patent document such as CN107606231A, CN107191621a, and the like, and will not be described herein. Obviously, the pressing mechanism is simply replaced by other existing pressing intermittent motion mechanisms, and the effect is foreseeable.
Example 2
Referring to fig. 14-20, the main difference between this embodiment and embodiment 1 is that the eccentric relationship of the receptacle 22 and the corresponding water passing port of the holder 23 is exchanged. In a specific structure, the receiving seat and the fixing seat are still integrated, a convex column 223 is disposed at the lower end of the receiving seat 22, a through hole is engraved at the bottom of the convex column, and the through hole is communicated with the third water passing port 222 upwards, and the through hole forms the first water passing port 221. The through hole 221 has a constant cross-sectional area of the through flow along the inflow direction of the water flow and a cross-section perpendicular to the direction of the water flow, and does not have a monotonically changing characteristic of the cross-sectional area along the rotation stroke direction, so that it always has the same cross-sectional area change rate with respect to the rotation of the fixed seat 23, thereby defining a cross-section having a linear characteristic.
Correspondingly, the upper end of the fixed seat 23 is provided with a flow regulating cavity 232, a section of curved transition slope 233 is arranged in the flow regulating cavity, and two ends of the transition slope are respectively connected with a high-level platform and a low-level platform. The inner and outer edges of the transition slope 233 are two curves with different curvature radii, a section with a smaller curvature radius in the two curves is connected with the inner edges of the high-level platform and the low-level platform, and a section with a larger curvature radius is connected with the outer edges of the high-level platform and the low-level platform.
The boss 223 is inserted into the flow regulating cavity 232 downwards, and a gap is formed between the bottom wall of the boss and the transition slope, and the gap forms the second water passing port 231. As in embodiment 1, from the geometric point of view of the notch 231, the rate of change of the through-flow cross-sectional area of the second water passing port 231 along the water flow direction monotonically increases, irrespective of whether the water flow flows in the flow regulating chamber 232 substantially along the surface circumference of the transition slope 233 or the water flow flows axially in the flow regulating chamber 232, so that the second water passing port 231 is defined to have an eccentric characteristic cross section.
The relative rotation direction of the bearing seat and the fixing seat is adjusted, so that the change rate of the through flow cross section area of the first water flow channel 24 along the rotation stroke is increased.
In fig. 19-20, two typical states of the spool are shown, namely a low flow state and a high flow state, respectively. It can be seen that in fig. 19, the degree of overlap of the first water passing port 221 and the second water passing port 231 is only a small part overlapping; in fig. 20, the first water passing hole 221 and the second water passing hole 231 are mostly overlapped due to the relative rotation of the socket 22 and the fixing base 23. Since the transition slope 233 has the above characteristics, the flow rate change rate at the position shown in fig. 20 is significantly larger than that at the position corresponding to fig. 19.
Example 3
Referring to fig. 21-25, the main difference between this embodiment and embodiment 1 is that the receiving base 22 and the fixing base 23 are both separate. In a specific structure, the bearing seat 22 comprises a bearing upper seat 223 and a movable ceramic plate 224 which are interlocked, and the fixed seat 23 comprises a fixed base 232 and a fixed ceramic plate 233 which are mutually fixed. The movable ceramic plate 224 is provided with a first overflow hole to form the first water passing hole 221; the ceramic tile 233 is provided with a second water passing hole to form the second water passing hole 231.
The hole edge of the first overflow hole 221 is formed by two circular arc connection transitions having the same radius of curvature, and the hole edge of the second overflow hole 231 is formed by two circular arc connection transitions having different radii of curvature. Thus, by the foregoing analysis, it is possible to obtain more easily: the first through-hole 221 has a similar configuration to the through-hole of embodiment 2, and has a linear characteristic section; and the second through-flow hole 231 has a construction similar to that of the transition wall of embodiment 1, having an eccentric characteristic section.
The relative rotation direction of the socket 22 and the fixing seat 23 is adjusted, so that the through flow cross section area of the first water flow channel 24 increases along the change rate of the rotation stroke.
In fig. 24-25, two typical states of the spool are shown, namely a low flow state and a high flow state, respectively. It can be seen that in fig. 24, the degree of overlap of the first water passing port 221 and the second water passing port 231 is only a small part overlapping; in fig. 25, the movable ceramic plate 224, the fixed base 232 and the fixed ceramic plate 233 are driven by the upper support 22 to rotate relatively, and the first water passing hole 221 and the second water passing hole 231 are mostly overlapped. Since the orifice edge of the first overflow orifice 221 has the above characteristics, the flow rate change rate at the position shown in fig. 25 is significantly greater than that at the position corresponding to fig. 24.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, but rather is intended to cover any equivalent structure modification made by the present invention, the description of which and the accompanying drawings, directly or indirectly, as applicable to other related technical fields.
