Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description merely illustrates a preferred embodiment of the utility model and that the utility model may be practiced without one or more of these details. In other instances, well known features have not been described in detail so as not to obscure the utility model.

According to one aspect of the present invention, a combination valve 100 is provided, as shown in FIG. 1. The combination valve 100 can be applied to various devices for controlling fluid (including liquid and gas) such as a water purifier. Therefore, according to another aspect of the utility model, a water purifier is also provided. The water purifier includes, but is not limited to, a household water purifier, a central water purifier, etc. The principles of the present invention will be described below in the context of an embodiment in which the fluid passing within the combination valve 100 is water.

As shown in fig. 1, the combination valve 100 may include a valve body 110, a check valve 200, and a solenoid valve 300.

The valve body 110 may be provided with a water inlet 111 and a water outlet 112. Illustratively, water may enter the valve body 110 through the water inlet 111 and exit through the water outlet 112.

The check valve 200 may employ various types of check valves known in the art or that may occur in the future. The solenoid valve 300 may employ various types of solenoid valves known in the art or that may occur in the future. The check valve 200 and the solenoid valve 300 may be disposed on the valve body 110 by any suitable means such as welding, clamping, coupling, etc. The check valve 200 and the solenoid valve 300 may be connected in series between the water inlet 111 and the water outlet 112. The sequence of the check valve 200 and the electromagnetic valve 300 between the water inlet 111 and the water outlet 112 is not limited. That is, after entering the valve body 110 through the water inlet 111, water may pass through the check valve 200 and the solenoid valve 300 in sequence, and then flow out through the water outlet 112; or after water enters the valve body 110 through the water inlet 111, the water can sequentially pass through the electromagnetic valve 300 and the one-way valve 200 and then flow out through the water outlet 112.

The check valve 200 may be used to control the one-way conductance of the valve body 110. That is, by providing the check valve 200, water can only flow from the inlet 111 to the outlet 112, but cannot flow from the outlet 112 to the inlet 111. The solenoid valve 300 may be used to control the on and off of the valve body 110. The water flow through the check valve 200 flows entirely through the solenoid valve 300. That is, there is no other water gap between the check valve 200 and the solenoid valve 300.

The principle of the present invention will be explained below by taking a water purifier shown in fig. 7 as an example. After the user finishes taking water, the electromagnetic valve 300 of the combination valve 100 controls the valve body 110 to be conducted. The pure water prepared in the reverse osmosis filter cartridge 420 is returned into the reverse osmosis filter cartridge 420 through the combination valve 100 to displace the concentrated water and the raw water in the reverse osmosis filter cartridge 420, so that the reverse osmosis filter cartridge 420 is completely filled with the water having the low TDS at the standby time. Like this, when next time getting water, the TDS of the first cup of water that the user received is lower, accords with operation requirement. After the replacement is completed, the electromagnetic valve 300 of the combination valve 100 controls the valve body 110 to stop, and the check valve 200 can prevent water from flowing reversely and entering the pure water end of the reverse osmosis filter element 420, so as to ensure that the water quality of the pure water meets the use requirement.

Therefore, the combination valve 100 of the present invention, which integrates the check valve 200 and the solenoid valve 300 by itself, can also avoid a case where the check valve and the solenoid valve are separately provided and connected using a pipe, on the basis of preventing the reverse flow of water. Therefore, the number of pipeline joints can be effectively reduced, and the cost of equipment is lower; the structural size of the equipment is small, so that the equipment is suitable for narrow spaces; meanwhile, the water leakage points of the equipment are correspondingly reduced, and the equipment is safer and more reliable.

The solenoid valve 300 is preferably a direct acting solenoid valve. The structure and operation principle of the direct-acting solenoid valve are known to those skilled in the art, and the description thereof is omitted for brevity. The direct-acting electromagnetic valve has the advantages of simple structure, few parts, quick response, sensitive action, simple control, wide application range and the like. Also, the solenoid valve 300 of this structure is easy to assemble and replace.

A preferred solenoid valve 300 is provided below, and as shown in fig. 2-6, the solenoid valve 300 may include a solenoid valve body assembly and a solenoid valve cartridge assembly. The solenoid valve body assembly may be provided with a solenoid valve water inlet 321 and a solenoid valve water outlet 322. The solenoid valve water inlet 321 may communicate with the water inlet 111. The solenoid valve outlet 322 may be in communication with the outlet 112. For example, water may enter the valve body 110 through the water inlet 111, and then flow out through the water outlet 112 after passing through the solenoid valve water inlet 321 and the solenoid valve water outlet 322 in sequence.

The solenoid valve spool assembly may be movable relative to the solenoid valve body assembly between an open position and a closed position. That is, when the solenoid valve spool assembly is in the open position, the solenoid valve water inlet 321 and the solenoid valve water outlet 322 are communicated. When the solenoid valve spool assembly is in the closed position, the solenoid valve water inlet 321 and the solenoid valve water outlet 322 are closed. When the electromagnetic valve core assembly is in the closed position, the electromagnetic valve core assembly is radially sealed with at least one of the electromagnetic valve water outlet 322 and the electromagnetic valve water inlet 321, so that at least one of the electromagnetic valve water outlet 322 and the electromagnetic valve water inlet 321 can be blocked. The radial seal means that along the radial direction of the water gap, a seal is formed between the valve core assembly of the electromagnetic valve and the corresponding water gap. Radial seals are opposed to axial seals. The axial seal means that the valve core assembly of the electromagnetic valve and the corresponding water gap form a seal along the axial direction. The adoption of radial sealing can improve the sealing reliability, thereby ensuring that the valve core assembly of the electromagnetic valve has stronger stopping capability on water, preventing water leakage and having stronger performance of the electromagnetic valve 300.

Further, as shown in fig. 2-6, the valve body 110 may be provided with a mounting opening 120. The solenoid valve 300 may be installed at the installation opening 120. A sidewall 121 may be disposed within the mounting opening 120. The sidewall 121 may separate an inlet chamber 131 and an outlet chamber 132 within the valve body 110. The inlet chamber 131 may communicate between the inlet 111 and the solenoid valve inlet 321. The water outlet chamber 132 may be in communication between the water outlet 112 and the solenoid valve water outlet 322. That is, water may enter the valve body 110 through the water inlet 111, and then sequentially pass through the water inlet chamber 131, the solenoid valve water inlet 321, the solenoid valve water outlet 322, and the water outlet chamber 132, and then flow out through the water outlet 112. Through the arrangement, the valve body 110 is convenient to process and manufacture and low in cost.

In a preferred embodiment, the sidewall 121 may have a ring shape. The inner side of the sidewall 121 may form an inlet chamber 131. The outer side of the side wall 121 may form an outlet chamber 132. Such a side wall 121 is convenient to process and low in manufacturing cost.

In a preferred embodiment, as shown in fig. 2-6, the solenoid valve body assembly may include a solenoid valve housing 310 and a resilient spacer assembly 320. The solenoid housing 310 may be provided with a solenoid housing opening 311 opposite the mounting opening 120. The solenoid valve housing 310 may be attached to the valve body 110 by welding, gluing, or the like.

The edge of the resilient partition assembly 320 is sandwiched between the edge of the mounting opening 120 and the edge of the solenoid housing opening 311. The solenoid valve water outlet 322 and the solenoid valve water inlet 321 may be disposed at any suitable location on the resilient partition assembly 320. The solenoid valve inlet 321 may be aligned with the inlet chamber 131. The solenoid valve outlet 322 may be aligned with the outlet chamber 132.

By clamping the resilient partition member 320, the sealing between the edge of the mounting opening 120 and the edge of the solenoid housing opening 311 is improved, water leakage is prevented therefrom, and the performance of the combination valve 100 is reliable.

Further, as shown in fig. 2-6, the elastic partition assembly 320 may include an elastic membrane 323 and a fixed cover 324. The edge of the elastic diaphragm 323 may be sandwiched between the edge of the mounting opening 120 and the edge of the solenoid housing opening 311. The fixing cover 324 may be fixed to the elastic membrane 323 by various means such as adhesion, snap-fit, etc. at a side facing the solenoid housing 310. The solenoid valve water inlet 321 and the solenoid valve water outlet 322 both penetrate through the elastic membrane 323 and the fixed cover 324. Wherein an edge of the stationary cover 324 may abut an edge of the mounting opening 120 when the solenoid valve cartridge assembly is in the closed position. By providing the fixing cover 324, a certain strength can be provided for the elastic diaphragm 323, so that the elastic diaphragm 323 can be prevented from being deformed by an excessive impact force of the valve core assembly of the solenoid valve, and the performance of the solenoid valve 300 is unstable.

In a preferred embodiment, as shown in fig. 2-6, the solenoid valve spool assembly may include a solenoid valve spool 330 and a solenoid 340. The solenoid spool 330 may be movably disposed within the solenoid housing 310 between an open position and a closed position. When the solenoid valve core 330 is in the closed position, the solenoid valve core 330 pushes the elastic partition member 320, so that the elastic partition member 320 abuts against the side wall 121. This separates the inlet chamber 131 from the outlet chamber 132. Meanwhile, the solenoid valve core 330 may radially seal at least one of the solenoid valve water inlet 321 and the solenoid valve water outlet 322. Preferably, the end of the solenoid core 330 may be provided with a sealing portion 331, and the sealing portion 331 of the solenoid core 330 pushes against the elastic partition member 320. When the solenoid spool 330 is in the open position, the solenoid spool 330 may be spaced apart from the resilient partition assembly 320.

The solenoid 340 may be disposed outside the solenoid housing 310. The solenoid 340 may be used to control the movement of the solenoid 330 between the open and closed positions. Optionally, when the solenoid 340 is powered, the solenoid 330 may be controlled to be in the open position; when the electromagnetic element 340 is de-energized, the electromagnetic valve core 330 can be controlled to be in the closed position. Optionally, when the solenoid 340 is powered, the solenoid 330 may be controlled to be in the closed position; when the electromagnetic element 340 is de-energized, the electromagnetic valve core 330 can be controlled to be in the open position. The working principle of the valve core assembly of the solenoid valve is well known to those skilled in the art and is not described in detail.

Electrical connection of the solenoid 340 to other components may be facilitated by positioning the solenoid 340 outside the solenoid housing 310; meanwhile, the heat dissipation of the electromagnetic piece 340 is facilitated, and the electromagnetic piece 340 is prevented from being damaged due to overheating.

In a preferred embodiment, as shown in fig. 1-6, a one-way valve 200 may be disposed between the water inlet 111 and the solenoid valve 300. That is, after entering the valve body 110 through the inlet 111, the water passes through the check valve 200 and the solenoid valve 300 in sequence, and then flows out through the outlet 112. Thus, the check valve 200 can also provide a damping effect if the combination valve 100 is used on a water path where water pressure fluctuations are large.

Preferably, as shown in fig. 1 to 6, the check valve 200 may be detachably mounted to the valve body 110 through the water inlet 111. In the embodiment shown in the figures, the check valve 200 is threadably mounted to the valve body 110. In other embodiments not shown, the check valve 200 may be mounted to the valve body 110 by a variety of means, such as by a connector, snap fit, or the like. With this arrangement, the check valve 200 can be individually replaced or cleaned.

A preferred one-way valve 200 is provided below and may include a first one-way valve housing 211, a second one-way valve housing 212, a one-way valve spool 220, and a reset member 230, as shown in fig. 2-6.

The first one-way valve housing 211 and the second one-way valve housing 212 may be separately connected by various means such as insertion, screw connection, adhesion, etc. First one-way valve housing 211 and second one-way valve housing 212 may enclose one-way valve passage 213.

Both the check valve spool 220 and the reset piece 230 may be received in the check valve passage 213. The check valve body 220 is movable between an on position where the check valve passage 213 is turned on and an off position where the check valve passage 213 is turned off. The reset member 230 may be used to apply a force to the check valve spool 220 toward the off position. Preferably, the restoring member 230 may be a spring.

Thus, when water passes through the check valve 200, the water pressure presses the check valve element 220, and when the water pressure is greater than the force applied by the reset member 230 to the check valve element 220 toward the off position, the water pressure may move the check valve element 220 to the on position, at which the check valve passage 213 is turned on. When the water pressure is less than the force applied by the reset element 230 to the check valve spool 220 toward the off position, the reset element 230 may move the check valve spool 220 to the off position, at which the check valve passage 213 is blocked. The one-way valve 200 is simple in structure and low in production and manufacturing cost. And because the first one-way valve housing 211 and the second one-way valve housing 212 are separately connected, the assembly of the one-way valve element 220 and the reset member 230 can be facilitated, and the assembly cost of the one-way valve 200 is also low.
