Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0015] To keep the drawings concise, only the parts relevant to this invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0016] First Embodiment Please see Figure 1-2 The technical solution of the outer casing integrated operation button structure provided in this embodiment includes the following: The outer housing 1 has an electromagnetic valve 2 at the bottom of its inner cavity. The top of the electromagnetic valve 2 is fixed in the inner cavity of the outer housing 1 by an electromagnetic valve fixing block 3. The electromagnetic valve fixing block 3 has a first guide 31. The second guide member 4 is disposed at the bottom of the upper end face of the outer housing 1, and the inner cavity of the second guide member 4 is in continuous contact with the upper end face of the outer housing 1. The control component 5 is disposed in the inner cavity of the outer housing 1. The head and tail of the control component 5 can slide up and down in the second guide 4 and the first guide 31 respectively. The tail end is connected to the switch of the solenoid valve 2. A sealing element 6 is disposed between the inner cavity of the control element 5 and the second guide element 4 to isolate the inner cavity of the outer housing 1 from the outside.

[0017] In specific implementation, as shown in the appendix Figure 1 As shown, the outer shell of the large frame is the outer casing 1. The hollow cylindrical structure at the top of the inner cavity of the outer casing 1 is the second guide 4. The bottom of the outer casing 1 is the solenoid valve 2. The structure above the solenoid valve 2 and connected to the solenoid valve 2 is the solenoid valve fixing block 3. The first through hole in the solenoid valve fixing block 3 is the first guide 31. The structure passing through the first guide 31 is the solenoid valve control needle. The lower end face of the solenoid valve control needle is in contact with the switch of the solenoid valve 2. The upper end face of the solenoid valve control needle is almost flush with the upper end face of the second through hole in the second guide 4.

[0018] Specifically, the inner cavity of the second guide member 4 includes a second through hole and a third through hole arranged coaxially from top to bottom, and the outer diameter of the third through hole is larger than the outer diameter of the second through hole.

[0019] Specifically, the control element 5 is a solenoid valve control needle. The control element 5 includes a main control element 51 and a first limiting element 52 and a second limiting element 53 arranged around the upper half of the main control element 51. The area between the lower end face of the first limiting element 52, the upper end face of the second limiting element 53 and the outer wall of the main control element 51 is the sealing element installation area 7.

[0020] Specifically, the outer diameters of the first limiting member 52 and the second limiting member 53 are matched with the inner diameter of the third through hole; the outer diameter of the main control member 51 is matched with the outer diameter of the second through hole.

[0021] In practical implementation, under this structural and dimensional design, since the third through hole is larger than the second through hole, and the outer diameters of the first limiting member 52 and the second limiting member 53 match the inner diameter of the third through hole, it is not difficult to conclude that the outer diameter of the first limiting member 52 is larger than the inner diameter of the second through hole. The surface of the second guide member 4 that is in contact with the upper end face of the third through hole generates a contact force with the first limiting member 52, thereby preventing the first limiting member 52 from slipping off.

[0022] Specifically, the sealing element 6 is a sealing ring, and the sealing element 6 is disposed in the sealing element mounting area 7.

[0023] In practice, the outer diameter of the seal 6 is preferably slightly larger than the inner diameter of the third through hole, so that the seal 6 can undergo elastic deformation to isolate the inside and outside without generating significant resistance to the downward movement of the solenoid valve control needle.

[0024] Specifically, the upper end face of the first limiting member 52 is chamfered to the side wall. This chamfer design helps guide the top of the solenoid valve control needle when it is inserted into the second guide member 4.

[0025] Specifically, the upper end face of the solenoid valve fixing block 3 and the first guide member 31 are chamfered. This chamfer design helps to guide the solenoid valve control when the tail end is inserted into the solenoid valve fixing block 3.

[0026] In specific implementation, the upper half of the solenoid valve control needle is installed inside the outer housing 1 after a sealing ring is assembled in the sealing installation area 7. The solenoid valve control needle is axially positioned and installed in the ejector pin cavity of the outer housing 1 after a dynamic sealing ring is pre-installed in the guide section of the solenoid valve fixing block 3. During product operation, according to production line operation requirements, the operator externally presses the solenoid valve control needle to cause axial displacement, thereby controlling the on / off state of the solenoid valve 2. The movement of the solenoid valve control needle directly drives the opening and closing action of the solenoid valve 2, thereby precisely controlling the opening and closing of the gas path of the vacuum generating mechanism, realizing the opening (generating vacuum) or closing (releasing vacuum) of the product vacuum state. When no force is applied to the solenoid valve control needle, the opening and closing of the solenoid valve 2 is controlled by the vacuum system and does not require external adjustment. When the circuit control malfunctions or external control is required, it can be achieved by pressing the solenoid valve control needle.

[0027] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
