[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] To achieve the above-mentioned purpose, the embodiment of the present invention provides a multi-unit integrated solenoid valve, referring to Figure 2-8 As shown, including:

[0035] A detachable box 1 having a sealed chamber, wherein an air inlet interface 2 is provided at the top of the box 1, and an integrated interface 3 is provided at the bottom of the box 1, wherein the air inlet interface 2 and the integrated interface 3 are in communication with the chamber;

[0036] A manifold valve assembly 4 for installation in the housing 1, wherein one end of the manifold valve assembly 4 is movable for use at the inner side of the integration interface 3;

[0037] A control valve wiring row 5 is arranged outside the housing 1 and electrically connected to the manifold valve assembly 4 , and the control valve wiring row 5 controls the manifold valve assembly 4 to form a flow passage or blockage for the integrated interface 3 .

[0038] Compared with the traditional complex structure of large-volume multi-airway connection composed of one valve and one airway, this embodiment has made great improvements and innovations. The sealed chamber is used as the air intake storage space, the collective valve assembly 4 is installed in the space, and the air outlet end is set as the integrated interface 3. The valve control wiring row 5 is used to control the collective valve assembly 4 to form ventilation or blocking of the integrated interface 3 to form an airflow, which solves the defects of the traditional valve seat that the ventilation pipeline is difficult to process and there is no internal space available, so the coil 7 can only be set outside to form a large volume. On the one hand, the sealed chamber can accommodate the installation and fixation of the collective valve assembly 4, and it does not need to be set outside the box 1. The overall volume is only the size of the box 1, the structure is simple, and the cost is greatly reduced; on the other hand, the airflow of the sealed chamber flows outward through the integrated interface 3, and one integrated interface 3 can match multiple airways at the same time, solving the trouble of traditional single airway intubation and complicated pipeline connections.

[0039] Specifically, the integrated valve assembly 4 arranged in the sealed chamber includes a fixed plate 6, an air outlet electromagnet body 7, and an exhaust electromagnet body 8. At least one fixed plate 6 is fixedly installed in the chamber by screws, and several air outlet electromagnet bodies 7 are arranged on the fixed plate 6. An exhaust electromagnet body 8 is arranged at the end of the fixed plate 6.

[0040] It should be noted that the air outlet electromagnet body 7 and the exhaust electromagnet body 8 used in the present invention are both electromagnets, which are different from traditional solenoid valves. Traditional solenoid valves require the design of components such as coils and gate valves, which make the entire solenoid valve structure larger in size. Multiple solenoid valves are arranged and spliced ​​to form a large volume structure. The electromagnets used in this embodiment are all electromagnets, and the electromagnetism is generated by winding a coil around the iron core inside the electromagnet. The magnetism of the electromagnet can be controlled by turning on and off the current, and the size of the magnetism can be controlled by the strength of the current or the number of turns of the coil; the size of the magnetism can also be controlled by changing the resistance to control the current size. The electromagnet has the advantages of simple structure and small size. The use of the electromagnet can be controlled by turning on and off the power, which is conducive to the miniaturization design of the product and further reduces the mold development cost.

[0041] In an optional embodiment, the number of fixing plates 6 is preferably two, which are arranged in two rows, and three air outlet electromagnet bodies 7 are arranged at intervals on each fixing plate 6, which are used to dock with the integrated interface 3 and form ventilation or air circulation. An exhaust electromagnet body 8 is arranged at the end of one of the fixing plates 6, and an exhaust hole 9 is provided on the box body 1. The exhaust hole 9 is located on the side of the air inlet interface 2. The exhaust electromagnet body 8 is connected to the exhaust hole 9 for exhaust and pressure maintenance. A pressure detection hole 12 for detecting the air pressure in the sealed chamber is provided on the box body 1, and the pressure detection hole 12 is located on the side of the air inlet interface 2. When it is detected that the air pressure in the sealed chamber is too high, the exhaust hole 9 can be controlled by the exhaust electromagnet body 8 to release the gas in the sealed chamber to reduce the air pressure. The maximum air pressure of the sealed chamber in this embodiment is 40kPa.

[0042] Furthermore, the exhaust electromagnet body 8 includes a first shell 801, a first magnetic core 802, a first electromagnet 803, a first coil 807, a first silicone plug 804, a first retaining spring 805 and a first spring 806. The first shell 801 is fixedly installed on the fixing plate 6. The first shell 801 is wrapped with a first electromagnet 803 with a middle portion passing through. The first electromagnet 803 is penetrated by a first magnetic core 802. The first coil 807 is wrapped around the outer periphery of the first magnetic core 802. One end of the first magnetic core 802 passes through the exhaust hole 9 and is provided with a first silicone plug 804 for forming ventilation or air circulation with the exhaust hole 9. The first magnetic core 802 is provided with a first retaining spring 805. A first spring 806 is provided between the first retaining spring 805 and the end face of the first electromagnet 803. After power is supplied to the first coil 807, the first magnetic core 802 shrinks inward so that the first silicone plug 804 tightly blocks the exhaust hole 9. At this time, the first spring 806 is compressed and the air pressure in the sealed chamber rises. When the air pressure exceeds the preset air pressure value (for example, air pressure value = 25kPa), power supply to the first coil 807 is stopped. Driven by the first spring 806, the first silicone plug 804 of the first magnetic core 802 stretches outward to release air, separating it from the exhaust hole 9, and the gas in the sealed chamber can be discharged.

[0043] Furthermore, the integrated interface 3 includes a groove socket 10, and a plurality of air outlet holes 11 are provided at the bottom of the groove socket 10, and the air outlet holes 11 correspond to the air outlet electromagnet body 7, and the air outlet electromagnet body 7 includes a second shell 701, a second magnetic core 702, a second electromagnet 703, a second coil 707, a second silicone plug 704, a second retaining spring 705 and a second spring 706. The second shell 701 is fixedly installed on the fixed plate 6, and a second magnetic core 702 is provided in the second shell 701. A second coil 707 is wound around the outer periphery of the second magnetic core 702. A movable second silicone plug 704 is provided at one end of the second magnetic core 702. The second silicone plug 704 acts on the inner side of the air outlet hole 11 to pass or block the airflow. A second retaining spring 705 is provided on the second magnetic core 702, and a second spring 706 is provided between the second retaining spring 705 and the end face of the second electromagnet 703.

[0044] In this embodiment, the number of the air outlet holes 11 provided at the bottom of the groove socket 10 is preferably 6, which correspond to the second silicone plug 704 of each air outlet electromagnet body 7, and the second silicone plug 704 is located in the sealed chamber. When power is supplied to the second coil 707, the second magnetic core 702 stretches so that the second silicone plug 704 tightly plugs the air outlet hole 11, cutting off the airway of the air outlet hole 11 corresponding to the electromagnetic valve 7. At this time, the stretched second magnetic core 702 drives the second spring 706 to be stretched. Of course, the 6 air outlet holes 11 can be blocked and the ventilation can be cut off at the same time, or one or more of them can be blocked, which can be controlled by the valve control wiring row 5 as needed; when the power supply to the second coil 707 is stopped, the second spring 706 resets and drives the second silicone plug 704 of the second magnetic core 702 to shrink inward to the original position, so that it is separated from the air outlet hole 11, and the gas in the sealed chamber can be supplied, and the gas is output to the corresponding air outlet hole 11.

[0045] Furthermore, the box body 1 includes a shell 13 with an opening at the upper end and a cover plate 14 . The cover plate 14 is airtightly connected to the opening of the shell 13 . The air inlet interface 2 and the control valve wiring row 5 are located on the cover plate 14 . The integrated interface 3 is located on the shell 13 .

[0046] Furthermore, an integrally connected mounting portion 15 is provided on the outer side of the bottom of the housing 13 , and a screw through hole 16 is provided on the mounting portion 15 .

[0047] In summary, the present invention provides a multi-unit integrated solenoid valve, which adopts a collective valve assembly 4 arranged in a chamber inside a box body 1, and the external air outlet is arranged as an integrated interface 3. The control valve terminal row 5 controls the collective valve assembly 4 to form ventilation or air blocking for the integrated interface 3. The external air circuit is integrated, the connection is convenient, the structure is simple, the volume is only the size of the box body 1, and the cost is low.

[0048] In addition, reference Fig. 9As shown, in order to achieve the above-mentioned purpose, the present invention also provides a multi-unit integrated solenoid valve system, including the multi-unit integrated solenoid valve as described in any one of the above items.

[0049] In an embodiment used in an application scenario, the multi-unit integrated solenoid valve is fixed to an appropriate position through a mounting portion 15, the air inlet interface 2 is connected to an external air pump, the control valve wiring row 5 is connected to an external control connection line, the control valve wiring row 5 is used to control the use of the outlet electromagnet body 7 and the exhaust electromagnet body 8 as needed, and the pressure detection hole 12 is connected to an external detection device with a pressure sensor to determine the air pressure of the sealed chamber and appropriately exhaust and reduce the pressure. In the initial state, the second magnetic cores 702 of the six outlet electromagnet bodies 7 are stretched outward, so that the second silicone plug 704 is blocked in the outlet hole 11, and the first magnetic core 802 of the exhaust electromagnet body 8 is contracted inward, so that the first silicone plug 804 blocks the exhaust hole 9. When in use, an air pump is used to supply air to the sealed chamber in the box body 1 to increase the internal air pressure. At this time, the control valve terminal block 5 controls the second silicone plug 704 of one or more air outlet electromagnet bodies 7 to separate from the air outlet 11, and the gas is discharged outward through an air outlet 11 in the integrated interface 3. It is used for equipment or components connected by pipelines. One integrated interface 3 can be paired with the airway transportation of multiple pipelines. The external air path is integrated, which avoids the trouble of complex and intertwined single pipeline plug-in in the past, greatly improving the convenience of use, small size and low cost.

In this way, when the gas enters the box body through the air inlet hole, a certain air pressure is formed in the sealed chamber. When any air outlet electromagnet body or exhaust electromagnet body is opened, gas can be transported to the corresponding airway for use by externally connected equipment.
