Description

Flow regulation and control device and bathroom equipment

Technical Field

The utility model relates to a bathroom technical field especially relates to a flow regulation and control device and bathroom equipment.

Background

The sanitary ware is a product applied to a toilet or a bathroom, and can be a closestool, a squatting pan, a hand basin or a bathtub and the like. In order to wash articles or parts of a user's body or clean sanitary equipment, corresponding waterways are generally provided in the sanitary equipment to control the flow of water and perform corresponding washing or cleaning functions.

A part of water channels in the sanitary equipment need to overflow redundant water in the water channels by utilizing a flow regulation structure, so that the final output flow of the water channels is maintained in a preset range. The pressure at the input end of the water flow is generally relatively stable, the output end of the water flow is easy to have drastic changes of the pressure due to the state switching of the load, and the drastic changes of the pressure generated at the output end of the traditional flow regulation structure easily cause the oscillation of the water flow, so that the stability of the output flow of the water path is low.

SUMMERY OF THE UTILITY MODEL

Therefore, a flow control device and sanitary equipment are provided to solve the problem that the stability of the output flow of the waterway is low because the flow control structure cannot respond to the pressure change of the output end in time.

A flow regulating device comprising:

the through-flow assembly is provided with a first flow passage and a second flow passage; the through-flow assembly is provided with a regulating hole between the first flow passage and the second flow passage; the output end of the second flow channel is used for connecting a load; and

the overflow assembly is provided with a feed cavity communicated with the first flow channel and an overflow cavity communicated with the second flow channel; a movable separation boundary is formed between the overflow cavity and the flow feed cavity; the opening degree of the outlet of the overflow cavity is limited by the position of the movable separation boundary.

According to the flow regulating device, when water flows through the flow regulating device, the water flows sequentially through the first flow channel, the regulating hole and the second flow channel and then is output to a load through the second flow channel. A part of water flow in the first flow channel flows into the feed cavity, and a part of water flow in the second flow channel flows into the overflow cavity. The water in the overflow cavity and the water in the feed cavity both generate pressure action on the movable separation boundary, so that the movable separation boundary generates position change under the action of medium pressure borne by two sides. Because the opening degree of the output port of the overflow cavity is restricted by the position of the movable separation boundary, the overflow flow of the overflow cavity can be changed when the pressure difference between the overflow cavity and the feed cavity is changed. The change of the overflow flow of the overflow cavity can adjust the pressure difference before and after the adjusting hole, so that the flow which passes through the adjusting hole and is output by the second flow channel is kept stable and is only influenced by the adjustment of the size of the adjusting hole. Because the output end of the second flow passage is used for connecting a load, and the water flow of the overflow cavity comes from the second flow passage, when the pressure intensity of the second flow passage changes due to the change of the load, the pressure intensity state in the second flow passage can be quickly transmitted to the overflow cavity, before the opening degree of the output port of the overflow cavity changes, the pressure intensity difference change between the inner side and the outer side of the output port of the overflow cavity can generate a short-time adjusting effect on the overflow flow of the overflow cavity, so that before the opening degree of the output port changes, the overflow flow can generate an instant response, the overlarge impact of the violently changed pressure intensity on a movable separation boundary is reduced, the oscillation influence on the two sides of the adjusting hole is reduced, and the stability of the flow passing through the adjusting hole is improved.

In one embodiment, the overflow assembly is provided with a main partition, and a part of the overflow cavity is positioned between the main partition and the movable partition boundary; and a part of the overflow cavity is communicated with the output port and is positioned on one side of the main partition part, which is back to the movable partition boundary.

In one embodiment, a gap is arranged between an inner wall of the overflow cavity facing the output port and the output port.

In one embodiment, a guide groove is formed in the overflow assembly; the guide groove is arranged around the output opening along the plane of the output opening.

In one embodiment, a through groove is formed in the overflow assembly; a part of the overflow cavity between the main partition part and the movable partition boundary is communicated with a part of the overflow cavity on one side of the main partition part, which faces away from the movable partition boundary, through the through groove; the width of the through groove is larger than the inner diameter of the input port of the overflow cavity.

In one embodiment, the overflow assembly comprises a housing provided with the main partition and a valve core connected to the movable partition boundary; the valve core is matched with the shell to form the output port; the valve core is movably arranged on the main partition part in a penetrating way.

The technical solution provided by the embodiments of the present invention is described below with reference to the accompanying drawings.

The utility model provides a bathroom equipment.

In some embodiments, the sanitary fitting comprises a body provided with a liquid bath. In one embodiment, the sanitary fixture may be a toilet. In another embodiment, the sanitary equipment may be any combination structure at least including a squatting pan and a water storage device.

In some embodiments, the sanitary fixture is provided with a spray waterway for directing a flow of water to flow. In one embodiment, the spray waterway is capable of directing a stream of water to the privacy of a sanitary user. In another embodiment, the sanitary equipment may be provided with a liquid pool, and the spray water path is used for guiding water flow to the liquid pool so as to wet the wall surface of the liquid pool or clean dirt on the wall surface of the liquid pool. In one embodiment, the spray water circuit is terminated by a load. In particular, the load may be a spray gun module, a water tap, a shower head or other device capable of forming a water flow outlet.

In some embodiments, as shown in fig. 1, the sanitary equipment includes a flow control device 100, and the flow control device 100 is used to form a partial boundary of a spray waterway. And can control the output flow of the spray washing water path. Further, the flow control device 100 keeps the output flow constant by overflowing the excess water flow into the spray water path.

In some embodiments, the sanitary equipment is provided with a liquid storage container, and the water flow overflowing from the flow regulating device 100 can be stored in the liquid storage container. Furthermore, the stored water in the liquid storage container can be sent into the water channel again or flow into the liquid pool through other water channels to clean or wash the liquid pool.

Referring to fig. 1 to 9, the present invention further provides a flow control device 100.

In some embodiments, as shown in fig. 3 and 5, the flow regulating device 100 includes: a through-flow assembly 20 and an overflow assembly 30. The through-flow assembly 20 has a first flow passage 201 and a second flow passage 202. The through-flow assembly 20 is provided with a regulation hole 231 between the first flow passage 201 and the second flow passage 202. The output of the second flow path 202 is used to connect a load. The overflow assembly 30 has a feed chamber 301 connected to the first flow channel 201 and an overflow chamber 302 connected to the second flow channel 202. An active separation boundary is formed between the overflow chamber 302 and the feed chamber 301. The opening of the outlet 305 of the overflow chamber 302 is limited by the position of the movable separation boundary.

Specifically, when passing through the flow rate control device 100, the water flows through the first flow channel 201, the adjustment hole 231, and the second flow channel 202 in sequence, and then is output to the load through the second flow channel 202. A portion of the water in the first flow channel 201 flows into the feed chamber 301 and a portion of the water in the second flow channel 202 flows into the overflow chamber 302. The water in the overflow cavity 302 and the water in the feed cavity 301 both generate pressure on the movable separation boundary, so that the movable separation boundary generates position change under the action of medium pressure borne by the two sides. Since the opening degree of the output port 305 of the overflow chamber 302 is restricted by the position of the movable partition boundary, the overflow flow rate of the overflow chamber 302 can be changed when the pressure difference between the overflow chamber 302 and the feed chamber 301 varies.

Further, since the pressure in the second flow path 202 is decreased when the overflow volume of the overflow chamber 302 is increased and the pressure in the second flow path 202 is increased when the overflow volume of the overflow chamber 302 is decreased, a pressure difference between the front and rear of the adjustment hole 231 is adjusted, so that the flow passing through the adjustment hole 231 and outputted from the second flow path 202 is kept stable and is only affected by the adjustment of the size of the adjustment hole 231.

Because the output end of the second flow channel 202 is used for connecting a load, and the water flow of the overflow cavity 302 comes from the second flow channel 202, when the pressure of the second flow channel 202 changes due to the change of the load state, the pressure state in the second flow channel 202 can be quickly transferred to the overflow cavity 302, before the opening degree of the output port 305 of the overflow cavity 302 changes, the pressure difference change between the inner side and the outer side of the output port 305 of the overflow cavity 302 can generate a short-time adjusting effect on the overflow flow of the overflow cavity 302, so that before the opening degree of the output port 305 changes, the overflow flow can generate a transient response, the excessively large impact of the pressure which is changed violently on the movable separation boundary is reduced, the oscillation influence on the pressure state at two sides of the adjusting hole 231 is reduced, and the stability of the flow passing through the adjusting hole 231 is improved.

In some embodiments, as shown in conjunction with fig. 5 and 6, overflow assembly 30 includes a partition unit 60 for forming an active partition boundary. In some embodiments, the overflow assembly 30 further comprises a resilient member 70, the resilient member 70 being capable of at least partially counteracting a pressure of the medium in the feed chamber 301 beyond the overflow chamber 302. Specifically, the elastic member 70 is abutted between the housing 40 and the partition unit 60.

In some embodiments, as shown in fig. 3 and 4, the flow-dividing assembly 20 includes a first flow-dividing member 21, a second flow-dividing member 22, and an adjusting unit 23. The first flow splitter 21 serves to at least partially delimit the first flow channel 201. The second flow splitter 22 is configured to at least partially bound the second flow passage 202. The adjusting unit 23 is provided with an adjusting hole 231 and connected between the first flow dividing member 21 and the second flow dividing member 22. Specifically, the first flow splitter 21 is three-way and is formed with a first flow splitting port 211 for docking the feed flow chamber 301. The second flow diverter 22 is three-way and defines a second flow diversion port 212 for interfacing with the overflow chamber 302. Further, the overflow assembly 30 has a first protruding portion 425 communicating with the feeding cavity 301, the flow control device 100 further includes a first sleeve 80, one end of the first sleeve 80 is sleeved on the first protruding portion 425, and the other end of the first sleeve 80 is sleeved on a portion of the first flow splitter 21 having the first flow splitting port 211. So that the communication between the first flow channel 201 and the feed chamber 301 can be reliably completed. The overflow assembly 30 has a second protruding cylinder 426 communicated with the feeding cavity 301, the flow control device 100 further includes a second sleeve 90, one end of the second sleeve 90 is sleeved on the second protruding cylinder 426, and the other end of the second sleeve 90 is sleeved on the portion of the second flow divider 22 having the second flow dividing port 212. So that communication between the second flow passage 202 and the spill cavity 302 can be reliably accomplished.

In some embodiments, as shown in fig. 3 and 4 in combination, the adjustment unit 23 is at least partially capable of being deformed in a contracting manner. The through-flow assembly 20 further includes a first drain tube 24 having a rigidity. The adjusting unit 23 is connected between the first drain tube 24 and the second flow dividing member 22. Specifically, the adjusting unit 23 adjusts the size of the adjusting hole 231 by shrinkage deformation, and controls the flow rate finally output by the second flow passage 202. Since the first drain tube 24 and the second flow dividing member 22 have rigidity, the first drain tube 24 or the second flow dividing member 22 can be prevented from being deformed under the influence of the adjusting unit 23. Thereby ensuring that the adjustment holes 231 can perform a primary flow adjustment function. One end of the first draft tube 24 is connected to the adjusting unit 23, and the other end of the first draft tube 24 is adapted to be directly or indirectly butted to the first diverging part 21. Specifically, the adjustment unit 23 includes a compressible tube 232 and a hoop member 233, the compressible tube 232 is abutted between one end of the first draft tube 24 and one port of the second flow dividing member 22. The compressible tube 232 can be contracted and gathered in a radial direction, and the radial direction of the compressible tube 232 is perpendicular to the flowing direction of the water flow. The hoop member 233 is disposed outside the compressible tube 232 and keeps an abutting relationship with the compressible tube 232. The adjustment member 234 is screwed to adjust the tightening degree of the hoop member 233, so as to control the pressing force of the hoop member 233 against the outer side of the compressible tube 232. Specifically, the adjustment member 234 comprises a screw, or a screw and nut. When the hoop member 233 provides different pressures to the compressible tube 232, the compressible tube 232 is at different gathering degrees, so that the size of the adjusting hole 231 in the compressible tube 232 is changed.

In some embodiments, as shown in connection with fig. 3 and 4, the through-flow assembly 20 further includes a second drain tube 25 connected between the first drain tube 24 and the first flow divider 21. The second draft tube 25 has flexibility. In particular, since the second drainage tube 25 has flexibility, the position between the first flow dividing member 21 and the second flow dividing member 22 can be adjusted to some extent, which facilitates the flow through assembly 20 to adapt to the accommodating space in the sanitary ware. Further, the first sleeve 80 and the second sleeve 90 are flexible at the same time.

In some embodiments, as shown in fig. 5 and 6 in combination, the overflow assembly 30 is provided with a main partition 421, and a portion of the overflow chamber 302 is located between the main partition 421 and the movable partition boundary. The overflow chamber 302 also has a portion that communicates with the outlet 305 of the overflow chamber 302 and is on the side of the main partition 421 facing away from the active partition boundary. Specifically, it is assumed that a portion of the overflow chamber 302 between the main partition 421 and the movable partition boundary is the first sub-chamber 303, and a portion of the overflow chamber 302, which communicates with the output port 305 and is located on a side of the main partition 421 opposite to the movable partition boundary, is the second sub-chamber 304. When the water flows normally, the pressure of the first flow passage 201 and the pressure of the second flow passage 202 are kept stable, and the water flow does not flow through the first sub-chamber 303 but directly passes through the second sub-chamber 304, so that the impact of the water flow on the movable separation boundary can be reduced, and the stability of the opening degree of the output port 305 is improved. When the pressure of the second flow passage 202 changes, the water in the first sub-chamber 303 is replenished or discharged. For example, when the pressure in the second flow path 202 decreases relative to the pressure in the first flow path 201, the feed chamber 301 expands relative to the overflow chamber 302 and compresses the overflow chamber 302 via the active separation boundary, allowing the body of water in the first sub-chamber 303 to drain to the second sub-chamber 304. When the pressure in the second flow path 202 rises relative to the pressure in the first flow path 201, the spill cavity 302 expands relative to the feed cavity 301 and compresses the feed cavity 301 by moving the separation boundary, and the second flow path 202 provides a portion of the flow into the second sub-cavity 304 while additionally providing a portion of the flow into the first sub-cavity 303.

In some embodiments, as shown in connection with fig. 5, a gap is provided between an inner wall of the overflow chamber 302 facing the output port 305 and the output port 305. Therefore, the water flow in the overflow cavity 302 can flow to the output port 305 from different angles, and the feedback sensitivity of the overflow flow to the pressure change of the second flow channel 202 is improved.

In some embodiments, as shown in fig. 6 and 9, a channel 422 is provided in overflow assembly 30. The guide groove 422 is arranged around the outlet opening 305 along the plane of the outlet opening 305. Specifically, the guide groove 422 is used as a part of the first sub-chamber 303, when the water flows in the first sub-chamber 303, a part of the water can flow to positions at different angles relative to the output port 305 along the guide groove 422, so that the uniformity of the water flow entering the output port 305 can be improved, and the instantaneous overflow flow of the output port 305 is prevented from being limited.

In some embodiments, as shown in fig. 5 and 8, a through groove 423 is formed in the overflow assembly 30. A part of the overflow cavity 302 between the main partition 421 and the movable partition boundary communicates with a part of the overflow cavity 302 on a side of the main partition 421 facing away from the movable partition boundary via the through groove 423. The width of the through slot 423 is larger than the inner diameter of the inlet 306 of the spill cavity 302. Specifically, the main partition 421 at least partially forms a boundary of the through slot 423. Because the width of the through groove 423 is larger than the inner diameter of the input port 306 of the overflow cavity 302, after the water flow enters the through groove 423, the obstruction of the water flow can be reduced, and the water can flow to the first sub-cavity 303 or the second sub-cavity 304 more quickly. Further, the communication direction of the through groove 423 is parallel to the plane of the input port 306.

In some embodiments, as shown in connection with fig. 6, the relief assembly 30 includes a housing 40 provided with a main partition 421 and a valve cartridge 50 connected to the movable partition boundary. The valve cartridge 50 cooperates with the housing 40 to form an output port 305. The valve body 50 is movably inserted through the main partition 421.

Specifically, the outer diameter of the main portion 51 of the valve core 50 is matched with the inner diameter of the through hole of the main partition 421, so that the moving direction of the valve core 50 relative to the housing 40 is well defined. When the spool 50 moves along with the movable partition boundary and adjusts the opening degree of the output port 305, it is possible to avoid the influence on the adjustment accuracy of the output port 305 due to the deflection of the spool 50. More specifically, the end of the spool 50 remote from the movable partition boundary cooperates with the housing 40 to form the output port 305 of the spill cavity 302. More specifically, the housing 40 is formed with a cylindrical portion 424 on a side of the main partition 421 facing away from the movable partition boundary, and one end of the valve element 50 cooperates with an inner edge of the cylindrical portion 424 to form the output port 305. More specifically, the end of the valve element 50 remote from the movable partition boundary is provided with a tapered surface 52, and the tapered surface 52 cooperates with the inner edge of the cylindrical portion 424 to form the output port 305. The average outer diameter of the taper 52 decreases in a direction away from the active separation boundary. Further, the guide groove 422 is provided around the circumference of the cylindrical portion 424. In one embodiment, the output port 305 is annular.

In some embodiments, as shown in fig. 5 and 6, the housing 40 includes a housing cover 41, a housing body 42, and a cover plate 43. The partition unit 60 covers one of the openings of the housing body 42, and cooperates with the housing body 42 and the cover plate 43 to form an overflow chamber 302. Specifically, the partition unit 60 further covers an opening of the housing cover 41, and forms the feed chamber 301 in cooperation with the housing cover 41. More specifically, a main partition 421, a cylindrical portion 424, a guide groove 422, or a through groove 423 is provided to the case body 42. Further, the housing body 42 is provided with an output flow passage 427, and the water overflowing from the output port 305 of the overflow chamber 302 flows out of the housing body 42 through the output flow passage 427. In one embodiment, the resilient member 70 is a compression spring. More specifically, a gap is provided between an end of the cylindrical portion 424 facing away from the main partition 421 and the cover plate 43.

In some embodiments, as shown in fig. 5 and 6, the separating unit 60 includes a flexible pad 61, and the flexible pad 61 is supported between the housing body 42 and the housing cover 41, so as to prevent the water in the feed chamber 301 from leaking through a gap between the flexible pad 61 and the housing cover 41, or prevent the water in the overflow chamber 302 from leaking through a gap between the flexible pad 61 and the housing body 42. Specifically, the partition unit 60 further includes a pressing plate 62, the middle portion of the flexible mat 61 is clamped by the pressing plates 62 at both sides, and the pressing plates 62 at both sides of the flexible mat 61 are connected. Further, one of the pressing plates 62 is located on a side of the flexible pad 61 facing the main partition 421, and the elastic element 70 is abutted between the pressing plate 62 and the main partition 421.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
