Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a solenoid valve system. Background Technology

[0002] Vitrectomy is performed by using a vitrectomy machine or phacoemulsification machine to drive the vitrectomy head back and forth to cut the vitreous body. As disclosed in the prior art CN202310546690X, the main control element in the main unit used to control the air circuit is a solenoid valve. Especially when using a vitrectomy machine for posterior segment vitrectomy, the solenoid valve acts as a high-frequency, rapid switch during the operation, with switching times generally reaching 10,000 times / minute or even 15,000 times / minute. Such high-frequency and rapid on / off actions can easily lead to overall vibration, overheating, and noise problems in the solenoid valve, bringing many negative effects to the surgical environment. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems in the prior art and to provide a solenoid valve system.

[0004] The objective of this utility model is achieved through the following technical solution:

An inlet pipe and an outlet pipe are formed on the electromagnetic valve, and the inlet pipe and the outlet pipe extend through the inlet channel and outlet channel of the housing. A damping spring is disposed between the electromagnetic valve manifold and the inner wall of the housing to isolate the vibration of the electromagnetic valve from the housing.

[0023] The purpose, advantages, and features of this utility model will be illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of applying the technical solutions of this utility model, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this utility model.

[0024] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience and simplification of description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0025] like Figures 1 to 2 As shown, this utility model discloses a solenoid valve system, including a housing 1. Further, the housing 1 includes an inner housing 11 and an outer housing 12 nested together, with sound-insulating material 13 filling the space between them. Preferably, the sound-insulating material 13 in this utility model is made of known materials such as PVB film or sound-absorbing cotton, thereby reducing vibration noise during operation.

[0026] A solenoid valve manifold 21 is disposed within the housing 1. Furthermore, the solenoid valve manifold 21 is located within the inner housing 11, and the inner wall of the inner housing 11 is also provided with the sound-insulating material 13. The presence of sound-insulating material in both the inner and outer housings provides a double sound insulation effect, further reducing vibration noise. A damping spring 102 is disposed between the solenoid valve manifold 21 and the inner wall of the housing 1 to isolate the vibration of the solenoid valve 2 from the housing 1. The damping spring reduces the vibration generated by the solenoid valve during operation, thereby reducing vibration and the noise caused by vibration.

[0027] Specifically, such as Figure 3 As shown, the solenoid valve manifold 21 includes an integrally formed limiting part 211, a supporting part 212, and an abutting part 213. Preferably, in this invention, the limiting part 211 and the supporting part 212 are designed in a Z-shape, and the abutting part 213 is designed in an L-shape with the limiting part 211 and the supporting part 212. Figure 1 or Figure 2As shown, the two ends of the shock-absorbing spring 102 are fixedly connected to the abutment portion 213 and the inner housing 11, respectively. Furthermore, the limiting portion 211 includes two spaced and parallel limiting plates 2111 for limiting the movement direction of the solenoid valve 2.

[0028] Combination Figure 1 and Figure 2 As shown, a set of pipes is provided within the support portion 212 of the solenoid valve manifold 21. The pipes include at least one exhaust pipe 203 and a main pipe 204 connecting the output ends of all the exhaust pipes 203. Figure 2 As shown, the input end of each exhaust pipe 203 corresponds to a hole 20 of the solenoid valve 2; when the solenoid valve 2 is working, air is output to the exhaust pipe 203 and the main pipe 204 through the hole 20.

[0029] like Figure 1 As shown, since the solenoid valve 2 is in contact with the limiting plate 2111, friction will generate heat between them during the movement of the solenoid valve 2, which will affect the use of the solenoid valve 2. Therefore, a cooling structure 22 is provided on the limiting plate 2111 in this invention. Specifically, the cooling structure 22 is a set of cooling holes 220 provided on the limiting plate 2111. The input end of a set of cooling holes 220 located on the same horizontal line is connected to a cooling channel 2201, and the cooling channel 2201 is connected to the first output end of the main pipe 204. After air enters the main pipe 204, some of the air will dissipate heat to the outer surface of the solenoid valve 2 through the cooling channel 2201 and the cooling holes 220, eliminating the need for additional cooling equipment, ensuring the service life of the solenoid valve while simplifying the system structure and reducing costs.

[0030] Furthermore, such as Figure 1 As shown, the second output end of the main pipe 204 is an exhaust port, and a silencer 3 is connected to the exhaust port via a pipe. The silencer 3 is fixed above the limiting plate 211 by a mounting base 30 and is located in the inner housing 11. After air enters the main pipe 204, another portion of the air will enter the silencer 3 through a pipe and be discharged through the silencer; this portion of air can be fully utilized and reach a designated cooling location for cooling through an external air pipe.

[0031] like Figures 1 to 2 As shown, the housing 1 is provided with the following: Figure 4The solenoid valve 2 shown is fixed to the solenoid valve manifold 21. Further, the solenoid valve 2 is placed between the two limiting plates 2111 and located on the limiting part 211 and the support part 212. The support part 212 is also provided with a limiting rod 2121 that limits the movement direction of the solenoid valve 2, and the limiting rod 2121 is located on the outer wall of the solenoid valve 2. The vibration of the solenoid valve 2 is isolated from the housing 1 by the shock-absorbing spring 102 to reduce vibration and noise.

[0032] The solenoid valve 2 is a known two-position four-way or two-position five-way solenoid valve. An inlet pipe 201 and an outlet pipe 202 are formed on the solenoid valve 2, and an inlet channel 2011 and an outlet channel 2021 extending through the housing 1 are connected to the inlet pipe 201 and the outlet pipe 202.

[0033] Furthermore, any of the aforementioned solenoid valve systems is applied to a glass cutting machine. Specifically, there is one inlet channel 2011 connected to the solenoid valve 2, and the outer end of the inlet channel 2011 is connected to an air source, which includes, but is not limited to, known components with air supply functions such as a compressor pump. There are two outlet channels 2021 connected to the solenoid valve 2, and the outer ends of the outlet channels 2021 are connected to the dual-air-path glass cutting head air pipe in the glass cutting machine.

[0034] This utility model has many other embodiments. All technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of this utility model.
