Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic valve technology, specifically relating to an integrated low-pressure high-flow combined electromagnetic valve. Background Technology

[0002] Currently, smart bathroom products on the market typically use solenoid valves to control water flow. Solenoid valves offer convenient and timely water flow control, making them popular among manufacturers. However, in actual use, the water pressure in the pipes can sometimes be unstable, resulting in either high or low pressure. A patent with publication number CN110397130B discloses a constant pressure valve for automatically controlling water pressure, comprising an inlet pipe, a solenoid valve mechanism, a pressure reducing valve mechanism, and an outlet pipe. The two ends of the solenoid valve mechanism are connected to the inlet pipe and the pressure reducing valve mechanism, respectively, to open or close the water flow entering the pressure reducing valve mechanism from the inlet pipe. The outlet pipe is connected to the outlet end of the pressure reducing valve mechanism, which controls the inlet water flow at a constant pressure and constant flow rate before guiding it to the outlet pipe. The pressure reducing valve mechanism includes a pressure reducing valve body for water storage and a pressure reducing module installed on the valve body to reduce water pressure. Existing solenoid valves can often withstand high water pressure, but they have many connecting parts and unreliable sealing performance. Existing constant pressure valves include a solenoid valve body and a pressure-reducing mechanism, which are connected by pipelines. This results in a large overall structure for the constant pressure valve, limiting its installation. Therefore, there is a need to design an integrated low-pressure, high-flow-rate combined solenoid valve. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing an integrated low-pressure, high-flow-rate combined solenoid valve. The invention incorporates a pressure-reducing mechanism on the pressure-reducing connection channel inside the main valve body, resulting in good pressure reduction and easy installation. Furthermore, it connects the main water inlet channel and multiple water outlet channels via a central channel, enhancing its versatility.

[0004] The objective of this invention is achieved through the following technical solution: an integrated low-pressure, high-flow combined solenoid valve, comprising a main valve body, the main valve body including a main water inlet channel, with a brush ring water outlet channel and a bottom flush water outlet channel respectively provided on the left and right sides of the main water inlet channel; a brush ring water inlet chamber and a bottom flush water inlet chamber respectively provided on the top of the main valve body, with a sealing ring assembly between the brush ring water inlet chamber and the brush ring water outlet channel, and a sealing ring assembly also provided between the bottom flush water inlet chamber and the bottom flush water outlet channel; the sealing ring assembly includes a pressure relief channel, and the main valve body is provided with a first electromagnetic control component for controlling the opening or closing of the pressure relief channel; an intermediate channel connecting the main water inlet channel, the brush ring water outlet channel, and the bottom flush water outlet channel is provided; a vacuum breaker assembly is provided in the chamber of the main water inlet channel, and the main valve body is also provided with a pressure-reducing water path chamber and a pressure-reducing water outlet chamber connecting the main water inlet channel, with a pressure-reducing connection channel between the pressure-reducing water path chamber and the pressure-reducing water outlet chamber; a second electromagnetic control component is provided on the pressure-reducing water path chamber, and a pressure-reducing mechanism is provided on the pressure-reducing water outlet chamber.

[0005] Preferably, the sealing ring assembly includes a sealing ring body, a sealing ring bracket, and an anti-clogging spring; the first electromagnetic control assembly includes an inner sleeve, a first iron core, and a rubber core; the first iron core is slidably installed inside the inner sleeve, and the rubber core is fixedly installed at the end of the first iron core; the sealing ring bracket is provided with a pressure relief channel, and when the first electromagnetic control assembly is working, it drives the rubber core to move relative to the opening of the pressure relief channel; the bottom of the inner sleeve is pressed and installed on the edge sealing part of the sealing ring body, and the edge sealing part of the sealing ring body is fitted against the inner wall of the main valve body; the sealing ring body and the inner sleeve surround each other to form a back pressure chamber, and the anti-clogging spring is disposed in the back pressure chamber.

[0006] Preferably, the sealing ring bracket has a pair of protruding mounting portions, and the sealing ring body is fitted onto the protruding mounting portions; the anti-clogging spring includes a spiral portion and an extension portion, one end of the spiral portion abuts against the inner sleeve, and the other end of the spiral portion abuts against the sealing ring bracket; one of the protruding mounting portions has a mounting through hole, and the extension portion passes through the mounting through hole; the main valve body has a brush ring water inlet cavity and a bottom flush water inlet cavity, and a sealing ring assembly is provided in both the brush ring water inlet cavity and the bottom flush water inlet cavity; the extension portion passes through the mounting through hole and extends into the brush ring water inlet cavity or the bottom flush water inlet cavity.

[0007] Preferably, the first electromagnetic control assembly further includes an upper iron plate, a lower iron plate, a first encapsulated coil assembly, and a first spring. The main valve body is provided with a sealing groove, and the edge sealing part of the sealing ring body is installed in the sealing groove. The bottom of the inner sleeve presses against the edge sealing part of the sealing ring body. The lower iron plate is fixedly connected to the main valve body, and the lower iron plate is fitted to the outer horizontal end face of the inner sleeve. The first encapsulated coil assembly is provided between the upper iron plate and the lower iron plate, and the first encapsulated coil assembly is sleeved and installed on the outer layer of the inner sleeve. The first encapsulated coil assembly is hollow, and the upper iron plate and the lower iron plate extend into the first encapsulated coil assembly. The bottoms of the upper iron plate and the lower iron plate are snap-fit ​​connected.

[0008] Preferably, a first iron core is slidably installed inside the inner sleeve, and a rubber core is fixedly installed at the end of the first iron core; a first spring is provided between the first iron core and the inner wall of the inner sleeve, and when the first encapsulated coil assembly is energized, the first iron core drives the rubber core to move relative to the pressure relief channel.

[0009] When the first encapsulated coil assembly is energized, the first iron core moves the rubber core away from the pressure relief channel, thus opening the pressure relief channel. When the first encapsulated coil assembly is de-energized, the first iron core automatically resets under the action of the first spring, and the pressure relief channel automatically closes. When water enters the main water inlet channel, the water flows along the middle channel into the brush ring water inlet chamber and the bottom flush water inlet chamber, both of which are equipped with sealing ring assemblies. By default, the pressure relief channel is closed, so the water in the brush ring water inlet chamber and the bottom flush water inlet chamber enters the back pressure chamber through the mounting through hole on the sealing ring bracket, where there is a large water pressure. When the first encapsulated coil assembly is energized, the pressure relief channel opens, and the water pressure in the back pressure chamber drops. At this time, the sealing ring body elastically deforms, and the brush ring outlet channel and the bottom flush outlet channel are fully connected, generating a large impact force. Here, when the sealing ring body elastically deforms, the extension portion can expand and contract relative to the mounting through hole, thus preventing the mounting through hole from becoming blocked.

[0010] Preferably, the vacuum breaker assembly includes an anti-backflow seat, a vacuum cover, a fixing buckle, and a pair of sealing pads; the open end of the main valve body is provided with a detachable vacuum cover, and a fixing buckle is provided between the vacuum cover and the main valve body to fix the two; the vacuum cover is hollow, and the anti-backflow seat is disposed between the vacuum cover and the open end of the main valve body; sealing pads are fixedly installed on the upper and lower end faces of the anti-backflow seat, with one sealing pad facing the vacuum cover and the other sealing pad facing the open end of the main valve body.

[0011] When water enters the main water inlet channel, the water flow impacts the anti-backflow seat, and the sealing pad on the anti-backflow seat blocks the vacuum cover, thus preventing water from overflowing. The water can only flow into the brush ring inlet chamber and the underflume inlet chamber through the central channel. When rinsing is finished, negative pressure is generated in the brush ring inlet chamber and the underflume inlet chamber; at this time, the anti-backflow seat automatically falls under the action of gravity, and the sealing pad on the anti-backflow seat abuts against the outlet port of the main water inlet channel, thus preventing sewage from the brush ring inlet chamber and the underflume inlet chamber from flowing back into the main water inlet channel.

[0012] Preferably, one end of the pressure-reducing connection channel is provided with a second electromagnetic control component, and the other end of the pressure-reducing connection channel is provided with a pressure-reducing mechanism; the second electromagnetic control component includes a second encapsulated coil assembly and a second iron core, and when the second encapsulated coil assembly is energized, it controls the movement of the second iron core relative to the pressure-reducing connection channel; the pressure-reducing connection channel is located between the main water inlet channel and the vacuum breaker assembly, and the main water inlet channel is connected to the pressure-reducing water passage cavity.

[0013] Preferably, the pressure reducing mechanism is installed on the pressure reducing outlet chamber; the pressure reducing mechanism includes a pressure reducing valve body, a piston rod, and a seal; the seal is fixedly installed on the piston rod, the piston rod is slidably installed in the pressure reducing valve body, and the edge of the seal is fitted against the inner wall of the pressure reducing valve body; the pressure reducing valve body is provided with an air outlet, the pressure reducing valve body is provided with a first channel, and the seal is located at the opening end of the first channel; the first channel is located between the pressure reducing connection channel and the air outlet.

[0014] By default, the pressure-reducing connection channel is closed, and the second iron core is positioned near the open end of the pressure-reducing connection channel. When the water pressure inside the main valve body is high, the second encapsulated coil assembly controls the second iron core to move away from the pressure-reducing connection channel. This allows water to flow from the pressure-reducing water passage chamber into the pressure-reducing outlet chamber along the pressure-reducing connection channel. The water then impacts the piston rod, which in turn moves the seal. As the seal moves, the first channel opens, allowing water to flow out from the outlet, thus reducing the water pressure inside the main valve body.

[0015] Preferably, the intermediate channel and the pressure reducing connection channel are staggered vertically. The intermediate channel is connected to the main water inlet channel and the brush ring water inlet cavity, and is also connected to the main water inlet channel and the bottom flush water inlet cavity. The open end of the intermediate channel is provided with a sealing nut that is threadedly connected to it, and an O-ring is provided between the sealing nut and the intermediate channel.

[0016] By incorporating a central channel, the main water inlet channel can be easily connected to both the brush ring outlet channel and the bottom flush outlet channel, resulting in a smaller main valve body and easier installation. The central channel also features a sealing nut and O-ring for improved sealing.

[0017] Compared with the prior art, this utility model has the following advantages: 1. A pressure-reducing connection channel is set in the main valve body, and a second electromagnetic control component and a pressure-reducing mechanism are respectively set at both ends of the pressure-reducing connection channel, which facilitates pressure reduction of the main valve body in the working state and improves versatility; 2. The pressure-reducing connection channel is set inside the main valve body, making the overall structure of the solenoid valve lighter and easier to install; 3. The brush ring water outlet channel and the bottom flush water outlet channel are connected through the main water inlet channel and the intermediate channel respectively, which facilitates the control of multiple water circuits and improves versatility; 4. A sealing nut is provided on the intermediate channel, which improves the sealing performance of the intermediate channel. Attached Figure Description

[0030] The vacuum breaker assembly 9 includes an anti-backflow seat 91, a vacuum cover 92, a fixing buckle 93, and a pair of sealing pads 94. The main valve body 1 has a detachable vacuum cover 92 at its open end, and a fixing buckle 93 is provided between the vacuum cover 92 and the main valve body 1 to fix the two together. The vacuum cover 92 is hollow, and the anti-backflow seat 91 is disposed between the vacuum cover 92 and the open end of the main valve body 1. Sealing pads 94 are fixedly installed on the upper and lower end faces of the anti-backflow seat 91, with one sealing pad 94 facing the vacuum cover 92 and the other sealing pad 94 facing the open end of the main valve body 1.

The pressure reducing mechanism 15 is installed on the pressure reducing outlet chamber 13; the pressure reducing mechanism 15 includes a pressure reducing valve body 151, a piston rod 152, and a sealing element 153; the sealing element 153 is fixedly installed on the piston rod 152, the piston rod 152 is slidably installed inside the pressure reducing valve body 151, and the edge of the sealing element 153 is fitted to the inner wall of the pressure reducing valve body 151; the pressure reducing valve body 151 is provided with an air outlet 154, and a first channel 155 is provided inside the pressure reducing valve body 151, and the sealing element 153 is disposed at the opening end of the first channel 155; the first channel 155 is disposed between the pressure reducing connection channel 14 and the air outlet 154. The intermediate channel 11 and the pressure reducing connection channel 14 are staggered vertically. The intermediate channel 11 is connected to the main water inlet channel 2 and the brush ring water inlet cavity 5 respectively. The intermediate channel 11 is also connected to the main water inlet channel 2 and the bottom flush water inlet cavity 6 respectively. The open end of the intermediate channel 11 is provided with a sealing nut 17 that is threadedly connected to it. An O-ring 18 is provided between the sealing nut 17 and the intermediate channel 11.

[0031] The specific operation process of this embodiment is as follows: When the first encapsulated coil assembly 86 is energized, the first iron core 82 can drive the rubber core 83 away from the pressure relief channel 71, so the pressure relief channel 71 will be in the open state; when the first encapsulated coil assembly 86 is de-energized, the first iron core 82 will automatically reset under the action of the first spring 87, and the pressure relief channel 71 will automatically close. When water enters the main water inlet channel 2, the water flow enters the brush ring water inlet cavity 5 and the bottom flush water inlet cavity 6 along the middle channel 11 respectively. Both the brush ring water inlet cavity 5 and the bottom flush water inlet cavity 6 are equipped with sealing ring assemblies 7. In the default state, the pressure relief channel 71 is in the closed state, so the water flow in the brush ring water inlet cavity 5 and the bottom flush water inlet cavity 6 will enter the back pressure chamber 75 through the mounting through hole 77 on the sealing ring bracket 73. At this time, there is a large water pressure in the back pressure chamber 75. When the first encapsulated coil assembly 86 is energized, the pressure relief channel 71 opens, and the water pressure in the back pressure chamber 75 decreases. At this time, the sealing ring body 72 will elastically deform, and the brush ring water outlet channel 3 and the bottom flush water outlet channel 4 will be fully connected, thereby generating a large flushing force. Here, when the sealing ring body 72 elastically deforms, the extension 742 can expand and contract relative to the mounting through hole 77, thereby preventing the mounting through hole 77 from becoming blocked.

[0032] When water enters the main water inlet channel 2, the water flow impacts the anti-backflow seat 91, and the sealing pad 94 on the anti-backflow seat 91 blocks the vacuum cover 92, thus preventing water from overflowing. The water can only flow along the middle channel 11 into the brush ring water inlet chamber 5 and the bottom flush water inlet chamber 6 respectively. When rinsing is finished, negative pressure will be generated in the brush ring water inlet chamber 5 and the bottom flush water inlet chamber 6. At this time, the anti-backflow seat 91 will fall automatically under the action of gravity, and the sealing pad 94 on the anti-backflow seat 91 will abut against the water outlet of the main water inlet channel, thus preventing the sewage in the brush ring water inlet chamber 5 and the bottom flush water inlet chamber 6 from flowing back into the main water inlet channel 2.

[0033] By default, the pressure-reducing connection channel 14 is closed, and the second iron core 102 is positioned close to the open end of the pressure-reducing connection channel 14. When the water pressure inside the main valve body 1 is high, the second iron core 102 is moved away from the pressure-reducing connection channel 14 by the second sealed coil assembly 101. This allows water to flow from the pressure-reducing water passage chamber 12 along the pressure-reducing connection channel 14 into the pressure-reducing outlet chamber 13. The water then impacts the piston rod 152, which in turn moves the seal 153. When the seal 153 moves, the first channel 155 opens, allowing water to flow out from the outlet 154, thus reducing the water pressure inside the main valve body 1. By setting the intermediate channel 11, the main inlet channel 1 can be conveniently connected to the brush ring outlet channel 3 and the bottom flush outlet channel 4, resulting in a smaller main valve body 1 and easier installation. Furthermore, the pressure-reducing connection channel 14 is located inside the main valve body 1, further reducing the overall size of the main valve body 1.
