Description

Technical Field

[0001] This utility model relates to the field of vacuum machine technology, and in particular to a vacuum sealing machine with multiple sets of drainage components. Background Technology

[0002] A vacuum sealer is a device used to seal food, medicine, and other items. It works by removing air from the packaging, creating a low-oxygen environment that helps extend the shelf life of the goods and prevents oxidation and bacterial growth. Vacuum sealers are frequently used in homes, restaurants, and the food processing industry to maintain food freshness and extend its shelf life.

[0003] Existing vacuum machines incorporate an extraction port within the vacuum chamber to remove gas from vacuum bags and achieve vacuum sealing. However, in practice, the overly tight sealing rings around the vacuum chamber can block the air passage of the vacuum bag, thus affecting the efficiency of the extraction port. To improve gas extraction, telescopic guides are typically included in the main body. However, existing telescopic guide mechanisms generally only have a single guide, which guides the gas from the vacuum bag into the vacuum chamber through a narrow channel. This results in low extraction efficiency, affecting the vacuum sealing effect of the vacuum bag and increasing the operating time of the vacuum pump. Utility Model Content

[0028] Reference Figure 1 As shown, a vacuum sealing machine with multiple sets of drainage elements includes:

[0029] A cover 2 is rotatably mounted on one side of the main body 1; a cavity is formed inside the main body 1, and a telescopic flow guiding mechanism 3 is provided inside the cavity; several flow guiding elements 34 are provided inside the telescopic flow guiding mechanism 3, and a flow guiding channel is formed between two adjacent flow guiding elements 34. The flow guiding channel is configured to guide the gas in the vacuum bag into the vacuum chamber of the vacuum sealing machine. The telescopic flow guiding mechanism 3 facilitates the vacuuming operation of the smooth vacuum bag. By setting several flow guiding elements 34 inside the telescopic flow guiding mechanism 3, and forming multiple flow guiding channels between adjacent flow guiding elements 34, the gas flow path and area are significantly increased, which can guide the gas in the vacuum bag into the vacuum chamber more efficiently and reduce the amount of residual gas in the vacuum bag.

[0030] Furthermore, referring to Figure 1-3 As shown, a first panel 11 is provided on the main body 1. The first panel 11 is detachably connected to the main body 1. A cover 12 is provided on the first panel 11. A cavity is formed inside the cover 12. A telescopic guide mechanism 3 is provided inside the cavity. A lower chamber 111 is formed on the side of the first panel 11 near the cover 12. A protrusion 112 is formed on one side of the port of the lower chamber 111 towards the cover 2. In this embodiment, the protrusion 112 extends upward along the side wall of the cover 12 at the port of the lower chamber 111, so that a height difference is formed on both sides of the port of the lower chamber 111. An opening 114 is opened on one side of the protrusion 112 in the lower chamber 111. The opening 114 has expansion plates on both sides to separate the two sides of the vacuum bag, facilitating the insertion and retraction of the guide 34. The cavity also has a control component 5 with a controller. The cover 12 has multiple buttons that are electrically connected to the input of the controller. The buttons control the extension and retraction of the telescopic guide mechanism 3. The cover 12 has a cutter groove 121 near the buttons. The cutter groove 121 contains a cutter assembly 4. The cutter groove 121 is used for the movement of the cutter assembly 4, which is used to cut the vacuum roll bag. This allows the user to cut a vacuum bag that matches the size of the sealed item, reducing vacuum bag waste.

[0031] The first panel 11 has a first sealing ring groove along the edge of the lower chamber 111 and the protrusion 112. The first sealing ring groove is connected to the first sealing ring 13. The main body 1 has a heating component 113 on one side of the lower chamber 111. The first panel 11 has a plurality of locking seats. In this embodiment, the locking seats protrude from the first panel 11 on both sides near the lower chamber 111, which can make the heating component 113 and the pressure strip 22 fit tightly when fastened, and make the upper chamber 211 fit tightly with the lower chamber 111, thereby improving the sealing effect of the vacuum bag. As a result, a limiting groove is provided on one side of each locking seat. The limiting groove is used for the locking hook assembly to insert the hook on the locking hook assembly into the limiting groove when the locking hook assembly is in the locked state, so that the cover 2 and the main body 1 are tightly fastened together. The cover 12 is provided with a fixing seat on the side away from the cutter groove 121. The fixing seat is used to fix and connect with the sealing shell 38 of the telescopic flow guiding mechanism 3, so that a sealed environment is formed between the telescopic flow guiding mechanism 3 and the cover 12, which can prevent external gas from entering the telescopic flow guiding mechanism 3 and entering the vacuum chamber through the opening 114, thus affecting the vacuum sealing effect.

[0032] Furthermore, a second panel 21 is provided on the side of the cover 2 near the first panel 11. The first surface of the second panel 21, i.e. the side near the first panel 11, forms an upper chamber 211 that matches the lower chamber 111. A recess 212 that matches the protrusion 112 is formed on one side of the port of the upper chamber 211. A second sealing ring groove is provided on the second panel 21 along the edge of the port of the upper chamber 211. The second sealing ring groove is connected to a second sealing ring 23. When fastened, the upper chamber 211 and the lower chamber 111 form a vacuum chamber. The sealing rings of the upper chamber 211 and the lower chamber 111 fit tightly together, improving the airtightness of the vacuum chamber and preventing external gas from entering the vacuum chamber and affecting the sealing effect of the vacuum bag. A pressure strip 22 is provided on the first surface of the second panel 21 at the position corresponding to the heating component 113. A groove 213 is provided on the second panel 21 at the position corresponding to the cutter groove 121. The groove 213 is used for the cutter component 4 to be embedded.

[0033] The second side of the second panel 21, i.e., the side away from the first panel 11, has a matching lock groove corresponding to the lock seat. Connecting supports are provided on both sides of the lock groove. To improve the tightness of the fit between the cover 2 and the main body 1, a locking hook assembly is provided inside the cover 2. The locking hook assembly is correspondingly installed on the connecting support. The locking hook assembly includes a support, a cylinder, a push rod, a hook, and a spring. The support is connected to the connecting support. A connecting post is provided at the end of the support near the cylinder. The connecting post is used to limit the movement range of the push rod. A movable groove for the push rod to move is formed inside the support. Wings are spaced apart on the side of the support near the connecting support. The wings are adapted to the upper wing. The upper part has a lower slot that matches the upper slot. The upper and lower slots together form a rotating groove. Both sides of the hook have a rotating shaft. The hook rotates around the rotating groove through the rotating shaft to achieve the engagement and disengagement of the hook with the limiting groove. A push rod is slidably installed inside the support. The first end of the push rod is connected to the hook. The second end of the push rod will abut against the cylinder wall when the air is released. A spring is installed between the push rod and the support. A cylinder is installed outside the spring and connected to the support. The cylinder has an air hole. The air hole is electrically connected to a solenoid valve through a pipeline. In order to improve the stability when the hook is connected with the limiting groove, the hook has a stepped hook surface on the side that contacts the limiting groove.

[0034] Furthermore, referring to Figure 4-6 As shown, the telescopic flow guiding mechanism 3 is provided with several flow guiding components 34. Each flow guiding component 34 is fixedly connected to the slider 33. A flow guiding channel is formed between two adjacent flow guiding components 34. The flow guiding channel is used to guide gas into the lower chamber 111. A flow guiding wall is formed on the side of the flow guiding component 34 near the flow guiding channel to enhance gas flow. The shape of the flow guiding wall can be straight or wavy. In this embodiment, the flow guiding wall is set to wavy, so that the flow guiding channel as a whole forms wavy side walls. The wavy structure will generate a certain turbulence during the gas flow, accelerate the diffusion and flow speed of gas molecules, thereby improving the efficiency of gas entering the vacuum chamber and shortening the running time of the vacuum pump. In order to further improve the efficiency of the vacuum pump when pumping gas, multiple flow guiding channels can be provided on the surface of each flow guiding component 34 away from the slider 33. The flow guiding channels are multiple through grooves formed on the surface of the flow guiding component 34. Through the cooperation of the flow guiding channels and the flow guiding channels, the pumping efficiency of the vacuum pump and the rate of gas extraction from the vacuum bag are improved.

[0035] A slider 33 is connected to the second end of the guide member 34. A transmission assembly 35 is connected to the end of the slider 33 furthest from the guide member 34. The transmission assembly 35 includes a transmission rod 351 and a transmission element 352. The first end of the transmission rod 351 is connected to the slider 33, the second end of the transmission rod 351 is connected to the transmission element 352, and the other end of the transmission element 352 is connected to a motor 36. The transmission element 352 includes a driving wheel and a driven wheel. The driven wheel is connected to the transmission rod 351, and the driven wheel is connected to the driving wheel. The transmission assembly 35 can be a gear drive or a pulley drive assembly. A gear drive assembly can better control the extension and retraction of the guide member 34. In this embodiment, preferably... A gear transmission assembly is provided, in which the driving wheel and driven wheel achieve transmission through the meshing of their teeth. The driving wheel is connected to a motor 36, and the input end of the motor 36 is electrically connected to the output end of the controller. To make the movement of the guide member 34 more precise, a sensor is provided on the side of the slider 33 near the controller. The controller is provided with multiple sensor switches at the positions corresponding to the sensor. In this embodiment, the telescopic guide mechanism 3 is configured to switch between a first position, a second position, and a third position. In the third position, the guide member 34 extends from the opening 114 under the drive of the slider 33, and the third sensor switch on the controller causes the guide member 34 to... 4. The guide element 34 extends into the vacuum bag, positioning the opening of the air guide channel above the heating component 113. When the vacuum sealing machine executes the evacuation command, it guides the gas inside the bag into the vacuum chamber. In the second position, the guide element 34 retracts from the vacuum bag under the action of the slider 33, and retracts into the vacuum chamber via the second inductive switch on the controller. This allows users to shorten the extension time of the guide element 34 when sealing items in batches, thus improving sealing efficiency. In the first position, the guide element 34 is placed inside the chamber via the first limit switch on the controller, protecting it. In this embodiment, the controller is equipped with... There are three sets of limit switches: a first limit switch, a second limit switch, and a third limit switch. The position corresponding to the third limit switch, i.e., the guide 34, is above the heating component 113. The position corresponding to the second limit switch, i.e., the guide 34, is above the vacuum chamber. The position corresponding to the first limit switch, i.e., the guide 34, is inside the chamber. Therefore, the preset position of the guide 34 can be adjusted according to actual usage needs. For example, if performing batch food preservation operations, the guide 34 can be retracted to the vacuum chamber position to shorten the distance the guide 34 moves and improve work efficiency. If cleaning the main body, the guide 34 can be retracted into the cover 12.

[0036] The slider 33 is provided with a collar 332 that is adapted to the transmission rod 351. Hooks 331 are provided on both sides of the collar 332 and are connected to the slide rail 32. When the transmission rod 351 rotates, the slider 33 can move back and forth through the collar 332 and the hooks 331. Multiple connecting posts 334 are provided on the side of the slider 33 away from the collar 332. The connecting posts 334 are used to fix the flow guide 34 with bolts. A partition 333 is provided between two adjacent connecting posts 334. The partition 333 is used to separate the flow guides 34 on both sides, so that there is a gap between the flow guides 34 and a flow channel is formed. A retaining ring 335 is provided on the side of the slider 33 near the controller. The retaining ring 335 is used to install a sensor. When the slider 33 moves, the sensor senses the corresponding sensor switch, so that the slider 33 stops at the corresponding position and controls the extension or retraction position of the flow guide 34.

[0037] The telescopic flow guiding mechanism 3 is also provided with a housing 31 and a sealing housing 38. The sealing housing 38 is located outside the housing 31. A third sealing ring 37 is fitted at the opening of the sealing housing 38. The cross-sectional shape of the third sealing ring 37 is "U". A convex ring is provided around the sealing housing 38 on the side wall where the third sealing ring 37 fits. The third sealing ring 37 can prevent gas from entering from the connection between the sealing housing 38 and the fixed seat. The sealing housing 38 is used to improve the airtightness of the vacuum chamber and prevent gas from leaking into the vacuum chamber from the opening 114. The housing 31 is fixedly connected by bolts or adhesive. Multiple slide rails 32 are provided inside the housing 31. A slider 33 is slidably disposed on the slide rails 32. The slider 33 is used to drive the extension of the flow guiding component 34. As the slide block 33 retracts, one end is connected to the guide member 34. In order to reduce the pressure of the guide member 34 on the first sealing ring 13 and the second sealing ring 23, an abutment post is provided on the slide block 33. The abutment post is used to support the guide member 34 and is fixedly connected by bolts. The abutment post ensures that the height of the guide member 34 is above the first sealing ring 13 and does not contact the first sealing ring 13. In the closed state, the guide member 34 is pressed down by the rotation of the cover 2. However, the downward pressure of the guide member 34 is controlled by the connecting post 334, so that the guide member 34 only leaves an indentation on the side of the first sealing ring 13 near the heating component 113. As the number of uses increases, the indentation will not deepen. Therefore, the indentation has little impact on the vacuum degree of the vacuum sealing machine.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
