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 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 spray of water to the private parts of a sanitary user. In another embodiment, the sanitary installation is provided with a liquid bath, and the spray water path is used for guiding water flow to the liquid bath so as to wet the wall surface of the liquid bath or clean dirt on the wall surface of the liquid bath.

In some embodiments, the spray rinsing circuit may be divided into a front section, a middle section and a rear section which are connected in sequence. When flowing in the spray washing water path, the water flow passes through the front section, the middle section and the rear section in sequence.

In some embodiments, as shown in fig. 1, the sanitary equipment includes a water flow control device 100, and the water flow control device 100 can be used to form the boundary of the front section, the middle section or the rear section of the spray waterway and can control the output flow of the spray waterway to be maintained within a predetermined range.

In some embodiments, the sanitary equipment is provided with a liquid storage container, and stored water in the liquid storage container can be pumped into a spraying water channel or flows to a liquid pool through other water channels to clean or wash the liquid pool.

In some embodiments, the sanitary fitting includes a body, and the liquid bath is disposed on the body. In one embodiment, the sanitary installation further comprises a spray gun module, and the end of the rear section of the spray water path is formed at the spray gun module. 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.

Referring to fig. 1 to 6, the present invention further provides a water flow control device 100.

In some embodiments, as shown in fig. 3 and 4, the water flow control device 100 has a first liquid chamber 201, a second liquid chamber 301, and an adjusting port 302, wherein the adjusting port 302 is connected to the second liquid chamber 301. The first liquid chamber 201 and the second liquid chamber 301 communicate with each other through an orifice 21. The water flow enters the first liquid chamber 201 from the outside, and then sequentially passes through the orifice 21, the second liquid chamber 301, and the adjustment port 302. Specifically, the first liquid chamber 201 and the second liquid chamber 301 may be understood as components of the spray water path. In the case where the aperture size of the orifice 21 is constant, the flow rate through the orifice 21 is affected by the difference in liquid pressure between the first liquid chamber 201 and the second liquid chamber 301.

In some embodiments, as shown in fig. 3 to 5, the water flow control device 100 includes: first valve housing 20, second valve housing 30, separator assembly 40, and valve core 50. The first valve housing 20 serves to form part of the boundary of the first liquid chamber 201. The second valve housing 30 serves to form part of the boundary of the second liquid chamber 301. The second valve casing 30 has an outer peripheral portion 31 connected to the first valve casing 20 and a regulation portion 32 connected to the outer peripheral portion 31. The partition assembly 40 is disposed between the first valve housing 20 and the second valve housing 30 and is used to form an active partition boundary between the first liquid chamber 201 and the second liquid chamber 301. The valve core 50 is connected with the separation component 40 and is matched with the second valve shell 30 to form a regulating port 302, and the valve core 50 is at least partially arranged through the limiting part 32 in a sliding mode.

Specifically, when the liquid pressure difference between the first liquid chamber 201 and the second liquid chamber 301 changes, the medium pressure of the partition member 40 changes in the first liquid chamber 201 or the second liquid chamber 301. Because the partition assembly 40 is movably disposed relative to the first valve housing 20 and the second valve housing 30, when the pressure of the medium received by any side of the partition assembly 40 changes, the partition assembly 40 drives the valve core 50 to move relative to the second valve housing 30, so as to form the adjustment ports 302 with different sizes. The size of the adjusting port 302 affects the pressure drop of the water flow leaving the second liquid chamber 301, so that the pressure inside the second liquid chamber 301 can be adjusted, the liquid pressure difference between the first liquid chamber 201 and the second liquid chamber 301 can be maintained stable, and finally the flow rate through the water flow control device 100 can be kept constant. The restriction 32 provides a guiding action to the spool 50 to ensure the accuracy of the variable control of the regulated port 302. Because the limiting portion 32 is connected with the outer peripheral portion 31, when the outer peripheral portion 31 is abutted with the first valve casing 20 to form the second liquid chamber 301, the valve core 50 can be simultaneously nested into the limiting portion 32, and the abutting between the limiting structure and the outer peripheral portion 31 after the abutting between the outer peripheral portion 31 and the first valve casing 20 is completed is avoided, so that the assembly of the water flow control device 100 can be simplified, and the assembly efficiency is improved.

Specifically, as shown in fig. 3 and 4, the medium pressure is a pressure applied to the partition member 40 by the liquid. Further, the water flow in the first liquid chamber 201 has pressure, so that a medium pressure can be generated on the partition assembly 40 according to the force-bearing area of the partition assembly 40, and the medium pressure provided by the water flow in the first liquid chamber 201 can push the partition assembly 40 in the direction of expanding the first liquid chamber 201. The water flow in the second liquid chamber 301 generates medium pressure in another direction to the separation assembly 40 under the action of pressure, and the medium pressure provided by the water flow in the second liquid chamber 301 pushes the separation assembly 40 in the direction of expanding the second liquid chamber 301.

Further, with respect to the spool 50 cooperating with the second housing 30 to form the regulated port 302, in one embodiment, as shown in connection with FIG. 4, the spool 50 cooperates with the land 32 to form the regulated port 302. In another embodiment, the valve spool 50 cooperates with the peripheral portion 31 to form the adjustment port 302. In yet another embodiment, the valve body 50 forms the adjustment port 302 in cooperation with the restriction portion 32 and other portions of the outer peripheral portion 31.

Further, with respect to the movable partition boundary, as shown in fig. 4, it can be understood that one side of the partition member 40 is a boundary of the first liquid chamber 201, and the other side of the partition member 40 is a boundary of the second liquid chamber 301. And the position of the partition member 40 is variable, such that movement of the partition member 40 causes either expansion of the first fluid chamber 201 and compression of the second fluid chamber 301, or compression of the first fluid chamber 201 and expansion of the second fluid chamber 301.

In some embodiments, as shown in fig. 3 and 4, the water flow control device 100 further includes an elastic member 60 received in the second liquid chamber 301. The elastic member 60 is abutted between the first valve housing 20 and the partition member 40. In particular, the resilient member 60 serves to balance the pressure of the medium in the first fluid chamber 201 over the second fluid chamber 301. Since the elastic member 60 generates different magnitudes of elastic force by elastic deformation to balance the medium pressure of the first fluid chamber 201 beyond the second fluid chamber 301. When the pressure of the medium in the first fluid chamber 201 is different from that in the second fluid chamber 301, the elastic member 60 is at different lengths, so that the partition member 40 and the valve core 50 are at different positions relative to the second valve housing 30. When the spool 50 is in different positions with respect to the second valve housing 30, the regulation ports 302 can be formed in different sizes to regulate the pressure of the second fluid chamber 301.

In some embodiments, as shown in fig. 4, the limiting portion 32 is provided with an output port 321, and the second liquid chamber 301 is communicated with the output port 321 through the regulating port 302. Specifically, after the water flow in the second liquid chamber 301 exits the second liquid chamber 301 from the adjustment port 302, the water flow enters a space between the valve body 50 and the restriction portion 32. Then, the water flow between the valve body 50 and the limiting portion 32 is outputted through the output port 321, so that the water flow can be guided to the external pipe through the output port 321 and outputted to a predetermined position. More specifically, the output port 321 is provided at one side of the spool 50 in a direction perpendicular to the path of movement of the spool 50. Further, the spool 50 is restricted to a movable range that does not cover the output port 321.

In some embodiments, as shown in fig. 2 and 4 in combination, the second valve housing 30 is provided with a conduit part 33 connected to the defining part 32. The conduit portion 33 is provided around the output port 321. Therefore, the inner space of the duct portion 33 can communicate with the outlet 321, and a guiding effect is exerted on the outputted water flow. In one embodiment, an external conduit is provided around the conduit portion 33, the external conduit directing the flow of water to the spray gun module.

In some embodiments, as shown in connection with FIG. 4, the defining portion 32 is semi-open. The open end 322 of the defining portion 32 communicates with the second liquid chamber 301. The valve body 50 is provided with an inner flow passage 51. The space between the valve body 50 and the closed end 323 of the restriction portion 32 communicates with the second liquid chamber 301 through the inner flow passage 51. Specifically, when the limiting portion 32 is semi-open, an opening is provided as the open end 322 at one end of the limiting portion 32. The end of the defining portion 32 opposite to the open end 322 is closed as a closed end 323. In one embodiment, the open end 322 of the defining portion 32 is abutted against the peripheral portion 31, and the closed end 323 of the defining portion 32 is disposed away from the peripheral portion 31 relative to the open end 322, so that at least a part of the internal space of the defining portion 32 can communicate with the second liquid chamber 301. The end of the valve cartridge 50 remote from the partition assembly 40 penetrates from the open end 322 into the restriction 32. To ensure that the valve element 50 can move along a linear path, the valve element 50 has an abutting surface capable of contacting the inner wall of the defining portion 32. Further, the abutting surfaces are continuously or intermittently distributed along the length direction of the valve element 50. In order to ensure the accuracy of the guiding function, the shape of the abutting surface along the circumferential direction of the valve core 50 is close to the shape of the inner wall of the limiting portion 32, so that the inside of the limiting portion 32 is divided by the portion provided with the abutting surface to form two partial spaces, wherein the first partial space 324 can be communicated with the output port 321 and the adjusting port 302, and the second partial space 325 is located between the valve core 50 and the closed end 323 of the limiting portion 32 and is isolated from the first partial space 324. Since the limiting portion 32 is semi-open, the closed end 323 of the limiting portion 32 can prevent the water leaking from the gap between the abutting surface and the inner wall of the limiting portion 32 from overflowing to the outside of the water flow control device 100. Meanwhile, the inner flow passage 51 is communicated between the second partial space 325 and the second liquid chamber 301, so that the pressure in the second partial space 325 can be kept consistent with the pressure in the second liquid chamber 301, and the influence of the pressure condition in the second partial space 325 on the movement of the valve core 50 is avoided.

In some embodiments, as shown in fig. 2 and 4, the restriction portion 32 is cylindrical. One end of the regulation portion 32 is connected to the outer peripheral portion 31. The defining portion 32 is provided to be closed with respect to one end away from the outer peripheral portion 31. Specifically, the defining portion 32 is connected to the outer peripheral portion 31 at an end relatively close to the outer peripheral portion 31. The inner wall of the restriction portion 32 has a circular cross-section so as to provide a uniform guiding function to the valve element 50. Further, the projection of the abutting surface on a plane perpendicular to the central line of the limiting portion 32 is circular.

In some embodiments, as shown in connection with fig. 4, the second valve housing 30 is provided with a positioning groove 341. One end of the elastic member 60 is received in the positioning groove 341. So that one end of the elastic member 60 can be positioned. Specifically, the elastic member 60 is a compression spring.

In some embodiments, as shown in connection with fig. 2-4, the second valve housing 30 includes a transition portion 34 connected between the peripheral portion 31 and the defining portion 32. The transition portion 34 serves to form a boundary of the positioning groove 341. Transition 34 is on a side of peripheral portion 31 remote from divider assembly 40. Specifically, since the transition portion 34 is located at a side of the outer peripheral portion 31 away from the partition member 40, the depth of the positioning groove 341 can be increased without increasing the thickness of the second valve housing 30, so that the elastic member 60 having a larger initial length can be conveniently used, and the water flow control apparatus 100 can be applied to an environment with a relatively low medium pressure difference. More specifically, the outer diameter of the transition portion 34 is larger than the outer diameter of the limiting portion 32, so that the outer peripheral portion 31, the transition portion 34 and the limiting portion 32 are sequentially distributed in a step shape in a direction away from the first valve housing 20, and the outer shape of the second valve housing 30 can better correspond to the shapes of the valve core 50 and the elastic member 60, which is beneficial to reducing the volume of the water flow control device 100 and the space in the sanitary ware. Further, the outer peripheral portion 31 is in abutting engagement with the first valve housing 20 to keep the second liquid chamber 301 sealed.

Further, as shown in fig. 2, the limiting portion 32 and the transition portion 34 are coaxially disposed such that the center of the force applied to the partition member 40 by the elastic member 60 coincides with the valve core 50. The edge of the opening end 322 of the limiting portion 32 protrudes into the positioning groove 341, so that the impurities or the elastic member 60 accumulated in the transition portion 34 can be limited, the adjusting opening 302 is prevented from being blocked by the impurities or the elastic member 60 accumulated in the non-transition portion, and the movement of the valve core 50 relative to the opening end 322 is prevented from being influenced.

In some embodiments, as shown in connection with FIG. 4, the valve spool 50 is provided with at least two linearly distributed raised ring portions 52. Gaps are provided between adjacent raised ring portions 52. The collar portion 52 is received in the restriction portion 32. Specifically, an edge of the convex ring portion 52 is used to abut against an inner wall of the defining portion 32 to define the sliding direction of the valve element 50. More specifically, the abutting surface is provided on the circumferential outer edge of the collar portion 52. In order to avoid the influence of the excessive friction force on the smoothness of the movement of the valve element 50, the outer edge of the protruding ring portion 52 needs to be processed to remove burrs and improve the smoothness. Since the gaps are provided between the collar portions 52, the processing area is reduced. And the two convex ring parts 52 are arranged at intervals, so that the stability of the valve core 50 can be improved, and the shaking of the valve core 50 is reduced. More specifically, the outer diameter of the collar portion 52 is 75% to 99% of the inner diameter of the restriction portion 32. In one embodiment, the linear distribution direction between the plurality of convex ring portions 52 is the longitudinal direction of the valve element 50. The water flow control device 100 further includes a sealing ring 70 sleeved on the valve core 50, the sealing ring 70 is located between any two of the convex ring portions 52, so as to prevent water flowing between the valve core 50 and the closed end 323 of the limiting portion 32 from flowing to the output port 321 through a gap between the convex ring portion 52 and the inner wall of the limiting portion 32, and prevent the adjusting function of the adjusting port 302 from being affected.

Further, as shown in fig. 3 and 4, the valve core 50 is provided with a narrowed portion 53, and the narrowed portion 53 is located between the convex ring portion 52 and the partition member 40. The constriction 53 has a large end 531 and a small end 532. The average outer diameter of the constriction 53 decreases and varies in the direction from the large end 531 to the small end 532. The direction from the large end 531 to the small end 532 is the same as the direction of the constriction 53 facing away from the partition element 40. The narrowing portion 53 cooperates with the port edge of the open end 322 of the defining portion 32 to form the adjustment port 302. When the narrowed portion 53 is located at different positions relative to the limiting portion 32, the narrowed portion 53 has different cross sections and is located in the same plane with the port edge of the open end 322, so that the adjustment ports 302 with different sizes can be formed. The tuning orifice 302 creates different pressure drops for the water flow therethrough at different sizes.

Understandably, when the first liquid chamber 201 and the second liquid chamber 301 communicate through the orifice 21, the flow rate through the orifice 21 can be understood as the flow rate output from the output port 321. The magnitude of the flow rate through the orifice 21 is affected by the pressure difference between the first liquid chamber 201 and the second liquid chamber 301, and the change in the magnitude of the regulation port 302 can stabilize the pressure difference between the first liquid chamber 201 and the second liquid chamber 301. More specifically, when the pressure of the second liquid chamber 301 rises relative to the pressure of the first liquid chamber 201, the partition member 40 moves in a direction of compressing the first liquid chamber 201, and at the same time, the narrowing portion 53 moves in a direction of withdrawing from the defining portion 32, and the narrowing portion 53 cooperates with the port of the open end 322 of the defining portion 32 with a relatively small outer diameter to form the regulating port 302, thereby reducing the pressure to the water flow, and reducing the pressure of the second liquid chamber 301 to restore the pressure difference between the first liquid chamber 201 and the second liquid chamber 301 to an equilibrium state. When the pressure of the second liquid chamber 301 is reduced relative to the pressure of the first liquid chamber 201, the partition member 40 moves in the direction of compressing the second liquid chamber 301, and simultaneously the narrowing portion 53 moves in the direction of penetrating into the limiting portion 32, and the narrowing portion 53 is matched with the port of the open end 322 of the limiting portion 32 to form the regulating port 302, so that the pressure to the water flow is increased, the pressure of the second liquid chamber 301 is increased, and the pressure difference between the first liquid chamber 201 and the second liquid chamber 301 is restored to a balanced state. Therefore, the pressures before and after the orifice 21 can be kept uniform, so that the flow rate passing through the orifice 21 and output from the output port 321 can be kept stable.

In some embodiments, as shown in fig. 3 and 4, the separating assembly 40 includes a flexible sheet 41 and a clamping block 42. The shape of the flexible sheet 41 is variable, while the clamping block 42 has a relatively stable shape, and the amount of any spatial variation of the first fluid chamber 201 or the second fluid chamber 301 is close to the product between the projected area of the clamping block 42 and the displacement of the clamping block 42 in the projected direction. Thereby enabling the size of the adjustment port 302 to be linearly related to the amount of spatial variation of the first fluid chamber 201 or the second fluid chamber 301. Further, the projection direction is arranged in parallel with the sliding direction of the spool 50. Understandably, as the distance between the edge of the clamp block 42 and the first or second valve housing 20, 30 is smaller, the amount of any spatial variation of the first fluid chamber 201 is closer to the product. In one embodiment, the peripheral edge of the flexible sheet 41 is abutted between the first valve housing 20 and the second valve housing 30, and the two side clamping blocks 42 at the middle part of the flexible sheet 41 are abutted to make the middle part of the partition member 40 have a stable shape. Further, the valve core 50 is threadedly coupled to one of the clamping blocks 42 to achieve synchronous movement of the valve core 50 and the spacer assembly 40.

In some embodiments, as shown in fig. 4 and fig. 6, in order to prevent the collar 52 from moving to a position covering the output port 321, the first valve housing 20 is provided with a branch portion 22, and when the partition member 40 moves in a direction of compressing the first liquid chamber 201, the branch portion 22 is used to provide a limit abutment for the partition member 40, so as to limit the moving range of the valve element 50 before the collar 52 covers the output port 321. Specifically, as shown in fig. 3, an orifice 21 is formed in the first valve housing 20.

Further, as shown in fig. 1 and 3, the first valve housing 20 is further provided with an external port 23 and an interruption port 24. Any communication path between the external port 23 and the input port 202 of the first fluid chamber 201 passes through the interruption port 24. An external pipe in the sanitary equipment is nested and matched with the peripheral part of the external interface 23 to inject water flow into the external interface 23. The water flow control device 100 further includes a switch unit 80 for switching the on-off state of the interruption port 24. When the interrupt port 24 is blocked, the fluid flow from the external port 23 to the input port 202 of the first fluid chamber 201 is blocked in a closed state between the external port 23 and the input port 202. When the centering fracture 24 is unblocked, the outer port 23 and the input port 202 are in a communication state, and water flows into the first fluid chamber 201 through the outer port 23, the fracture 24, and the input port 202 in sequence. More specifically, the switch unit 80 includes an electromagnetic driving member 81 and a piston member 82. The piston member 82 is at least partially ferromagnetic and can be magnetically acted upon. The electromagnetic drive 81 is used to generate a magnetic field to adjust the position of the piston member 82 so that the piston member 82 abuts against the edge of the break 24 or away from the piston port. The electromagnetic drive 81 may be a coil.
