Description

Technical Field

[0001] This utility model relates to a vacuum sealing machine with a convenient water collection tank, which is applied in the field of vacuum sealing machines. Background Technology

[0002] A vacuum sealing machine is a device used to achieve vacuum packaging. It creates a vacuum inside the packaging bag by removing the air, thereby extending the shelf life of food, medicine and other items and maintaining their freshness.

[0003] Existing vacuum sealing machines have their air pumps directly connected to the negative pressure chamber. Therefore, when some bags, especially those containing food, are vacuumed, some high-moisture gas may enter the air pump, potentially causing water accumulation inside. This could affect the lifespan of the air pump components or the internal circuitry of the vacuum sealing machine. To address this issue, this invention designs a vacuum sealing machine with a convenient water collection tank. Utility Model Content

[0004] This invention provides a vacuum sealing machine with a convenient water collection tank, which can effectively solve the above problems.

[0005] This utility model is implemented as follows:

[0006] A vacuum sealing machine with a portable water collection tank includes:

[0007] A sealing machine housing, wherein a first groove is provided inside the sealing machine housing, an air extraction hole is provided in the first groove, an installation groove is provided on the sealing machine housing, and an air extraction pump is provided inside the sealing machine housing;

[0008] A collection device includes a collection tank installed in an installation groove. The collection tank includes a first through hole disposed on the upper side wall of the collection tank and a second through hole disposed on the side of the first through hole. The first through hole is connected to an air pump, and the second through hole is connected to an air extraction port.

[0009] The first groove is used to place the bag to be sealed;

[0010] The air pump is used to extract gas from the bag.

[0011] The collection tank is used to collect liquid that sinks due to gravity in the air when the air pump extracts gas.

[0012] As a further improvement, a first water tank connector corresponding to the first through hole is fixed inside the sealing machine housing, and a second water tank connector corresponding to the second through hole is provided below the first water tank connector. The first water tank connector is connected to the air pump through a conduit, and the second water tank connector is connected to the air extraction hole through a conduit. The collecting water tank is installed in the mounting groove, such that the first water tank connector is inserted into the first through hole, and the second water tank connector is inserted into the second through hole.

[0013] As a further improvement, the sealing machine housing includes a receiving groove disposed on the side wall of the sealing machine housing. A fastening detection device is disposed inside the sealing machine housing, including a sliding block disposed in the receiving groove. A compression spring is connected to one side of the sliding block, and the other end of the compression spring abuts against the inner side wall of the sealing machine housing. A button is connected to the other side of the sliding block. A slot is disposed in the middle of the sliding block, and an inclined protrusion is disposed on the side wall of the slot. The outer surface of the inclined protrusion is an inclined surface. A positioning element is disposed below the sliding block, and a positioning groove is disposed on the inner side wall of the positioning element. A pressing block is inserted into the positioning groove, and a first detection button abuts against the bottom of the pressing block. A first control board is disposed inside the sealing machine housing, and a first controller is disposed on the first control board. The first detection button is electrically connected to the first controller.

[0014] As a further improvement, the sealing machine further includes a sealing machine cover hinged to the sealing machine housing. The sealing machine cover includes buckles on both sides of the sealing machine cover corresponding to the fastening detection device. An embedding groove is provided on the side wall of the buckle. When the sealing machine cover and the sealing machine housing are fastened together, during the process of the buckle pressing down against the inclined protrusion, the sliding block compresses the compression spring. When the inclined protrusion is fully accommodated in the embedding groove, the buckle presses down on the pressing block, causing the pressing block to press the first detection button. The first detection button sends a fastening completion signal to the first controller.

[0015] As a further improvement, a vacuum sealing device is further included, comprising a vacuuming assembly disposed within the sealing machine housing and a sealing assembly disposed in front of the first groove.

[0016] The beneficial effects of this invention are as follows: the gas inside the bag first enters the second through-hole through the suction hole. Due to the density difference between the gas and the liquid, they separate in the gravitational field. The liquid is driven downward by gravity, while the gas continues to flow upward, thus separating the liquid and gas. The liquid collects in the collection tank, and the gas is drawn away by the suction pump through the first through-hole. This collection device achieves gas-liquid separation, preventing liquid from entering the sealing machine housing and preventing water from flowing into the suction pump, affecting the service life of the suction pump components or the internal circuitry of the vacuum sealing machine.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0036] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Reference Figures 1-3 As shown, a vacuum sealing machine with a fastening detection device includes: a sealing machine housing 10 including a sealing machine shell 11 and a sealing machine cover 12 hinged to the sealing machine shell 11; a vacuum sealing device 20 is provided inside the sealing machine shell 11; the vacuum sealing device 20 includes a vacuum pumping assembly 21 disposed inside the sealing machine shell 11; the vacuum pumping assembly 21 includes an air pump 211 disposed inside the sealing machine shell 11; a first groove 113 corresponding to the vacuum pumping assembly 21 is provided on the sealing machine shell 11; an air extraction hole 114 is provided on the first groove 113; and an installation groove 117 is provided on the side wall of the sealing machine shell 11.

[0038] Reference Figures 3-4 As shown, a collection device 50 is provided in the mounting groove 117. The collection device includes a collection water tank 51 disposed in the mounting groove 117. A first through hole 511 is provided above the side wall of the collection water tank 51. A second through hole 512 is provided to the side of the collection water tank 51 located on the first through hole 511. A first water tank connector 52 corresponding to the first through hole 511 is fixedly provided in the sealing machine housing 11. A second water tank connector 53 corresponding to the second through hole 512 is provided below the first water tank connector 52. A water tank connector 52 is connected to a vacuum pump 211 via a conduit, and a second water tank connector 53 is connected to a vacuum port 114 via a conduit. The collection water tank 51 is installed in the mounting groove 117, such that the first water tank connector 52 is inserted into the first through hole 511, and the second water tank connector 53 is inserted into the second through hole 512. When the vacuum pump 211 evacuates the bag in the first groove 113, the gas in the bag first enters the second through hole 512 through the vacuum port 114. Due to the density difference between the gas and the liquid, they are separated in the gravitational field. The liquid experiences a downward velocity due to gravity, while the gas flows into the first through-hole 511 through the second through-hole 512, thus separating the liquid and gas. The liquid collects in the collection tank 51, while the gas is drawn away by the vacuum pump through the first through-hole 511. Through this collection device 50, gas-liquid separation can be achieved, preventing liquid from entering the sealing machine housing 11 and preventing water from flowing into the vacuum pump, affecting the service life of the vacuum pump components or the internal circuitry of the vacuum sealing machine.

[0039] A bag fixing block 115 is provided on the first groove 113. The bag to be vacuumed is placed on the bag fixing block 115, and the sealing machine cover 12 and sealing machine housing 11 are fastened. The gas inside the bag is extracted by the vacuum pump 211 to achieve a vacuum effect.

[0040] A sealing component 22 is provided in front of the first groove 113. The sealing component 22 includes a heat sealing strip 221 provided on the sealing machine housing 11. The sealing machine cover 12 is provided with a heat sealing strip receiving groove 121 corresponding to the heat sealing strip 221. The sealing machine cover 12 and the sealing machine housing 11 are fastened together. After the air in the bag is completely extracted, the bag opening is heated by the heat sealing strip 221 to seal the bag opening.

[0041] Reference Figures 5-6 As shown, this utility model designs a low-cost negative pressure detection device 30. The negative pressure detection device 30 includes a control panel 31 disposed inside the sealing machine cover 12. The control panel 31 is provided with a controller 32 and a detection button 33. The controller 32 can be an STM32 series microcontroller. The controller 32 is electrically connected to the detection button 33. The bottom of the sealing machine cover 12 is provided with a second groove 122 corresponding to the first groove 113. When the sealing machine cover 12 and the sealing machine housing 11 are fastened together, the first groove 113 and the second groove 122 combine to form a negative pressure cavity. The sealing machine cover 12 is provided with a hollow mounting post 123 corresponding to the detection button 33. The mounting post 123 is provided with a through hole 124 communicating with the second groove 122. A negative pressure diaphragm 34 is provided on the mounting post 123. In the initial state, the negative pressure diaphragm 34 presses the detection button 33. When the vacuum assembly 21 extracts the air in the first groove 113... When the bag reaches a vacuum state, the negative pressure diaphragm 34 indents downwards in the middle, causing the negative pressure diaphragm 34 to release the detection button 33. The detection button 33 transmits a negative pressure signal to the controller 32. Upon receiving the negative pressure signal, the controller 32 indicates that the vacuuming operation is complete. This utility model replaces the traditional mechanical negative pressure detection device 30 with a detection button 33 and a negative pressure diaphragm 34. This method does not require a complex mechanical mechanism, has better stability, and can better complete the negative pressure detection work. The vacuum sealing machine can select a negative pressure diaphragm 34 of appropriate thickness so that when the gas pressure in the negative pressure chamber reaches a certain value, the negative pressure diaphragm 34 indents downwards. In one embodiment, when the gas pressure in the negative pressure chamber reaches -0.5 MPa, the negative pressure diaphragm 34 drops by 1.5 mm, thus allowing the detection button 33 to be released smoothly. Compared with a precise negative pressure detection module, this utility model can effectively reduce costs by using a detection button 33 and a detection diaphragm 34.

[0042] Reference Figures 7-11As shown, a receiving groove 116 is provided on the side wall of the sealing machine housing 11. A fastening detection device 40 is provided in the receiving groove 116. The fastening detection device 40 includes a sliding block 41 disposed in the receiving groove 116. A compression spring 42 is connected to one side of the sliding block 41, and the other end of the compression spring 42 abuts against the inner side wall of the sealing machine housing 11. A button 43 is connected to the other side of the sliding block 41. A slot 411 is provided in the middle of the sliding block 41, and an inclined protrusion 412 is provided on the side wall of the slot 411. The outer surface of 412 is an inclined surface. A positioning element 44 is provided below the sliding block 41. A positioning groove 441 is provided on the inner side wall of the positioning element 44. A pressing block 45 is inserted into the positioning groove 441. The pressing block 45 abuts against the first detection button 46 below. A first control board 47 is provided inside the sealing machine housing 11. A first controller 48 is configured on the first control board 47. The first detection button 46 is electrically connected to the first controller 48. The first controller 48 can be a single-chip microcomputer of the STM32 series.

[0043] The sealing machine cover 12 is provided with buckles 125 on both sides of the sealing machine cover 12, which correspond to the fastening detection device 40. An embedding groove 1251 is provided on the side wall of the buckle 125.

[0044] When the sealing machine cover 12 and the sealing machine housing 11 are fastened together, during the process of the buckle 125 pressing down against the inclined protrusion 412, the sliding block 41 compresses the compression spring 42. When the inclined protrusion 412 is fully accommodated in the embedded groove 1251, the buckle 125 presses down on the pressing block 45, causing the pressing block 45 to press the first detection button 46. The button sends a signal indicating that the fastening is complete to the first controller 48. The first controller 48 receives the signal indicating that the sealing machine housing 11 and the sealing machine cover 12 have completed the fastening operation. By pressing down on the fastening detection device 40 during the process of the buckle 125, the switch of the first detection button 46 can be triggered, thereby detecting whether the sealing machine cover 12 and the sealing machine housing 11 have completed the fastening. On the one hand, this can prevent the sealing machine cover 12 and the sealing machine housing 11 from being fastened together. The poor sealing of the negative pressure chamber prevents complete vacuum extraction of the bag, resulting in residual air inside the bag. Furthermore, during the heat-sealing process, the heat-sealing blade on the upper cover may not completely seal the bag, leaving a gap at the bag opening that allows air to enter and cause spoilage. On the other hand, detecting whether the upper cover 12 and the sealing machine housing 11 are properly engaged can effectively improve the detection accuracy of the negative pressure detection device 30. Since the design of this product is pre-calculated during manufacturing, the required pressure for the negative pressure diaphragm 34 to indent downwards and release the detection button 33 is precisely calculated. Therefore, if the upper cover 12 and the sealing machine housing 11 are not properly engaged, gas leakage within the negative pressure chamber will prevent the chamber from reaching the specified pressure value, affecting the detection results.

[0045] The sealing machine housing 11 includes an upper housing 111 and a lower housing 112. The positioning member 44 is fixed in the upper housing 111 by bolts. The side wall of the positioning groove 441 is provided with an opening groove 442. The side wall of the pressing block 45 is provided with an extension block 451 that is adapted to the opening groove 442. The extension block 451 is disposed in the opening groove 442. The buckle 125 presses the extension block 451 downward so that the pressing block 45 presses the first detection button 46. Since the pressing block 45 and the first detection button 46 are both circular in shape, the extension block 451 can effectively prevent the pressing block 45 from rotating.

[0046] A hollow positioning block 443 is provided below the positioning groove 441. A button limiting block 444 is provided on each of the four sides of the positioning block 443. A limiting post 445 is provided below the positioning member 44 in the lower housing 112. The first detection button 46 abuts against the upper limit post 445. When the positioning member 44 is locked and fixed in the upper housing 111, the button limiting block 444 abuts against the upper surface of the first detection button 46. The button limiting block 444 abuts against the periphery of the first detection button 46, so that the first detection button 46 can be fixed inside the sealing machine housing 11. This prevents the first detection button 46 from shifting when the sealing machine is moved, which would prevent the pressing block 45 from pressing the first detection button 46 and affect the fastening operation between the sealing machine housing 11 and the sealing machine cover 12.

[0047] A first limiting block 413 is symmetrically arranged on the side wall of the sliding block 41, and a second limiting block 446 corresponding to the first limiting block 413 is arranged above the positioning member 44. When the sliding block 41 is installed above the positioning member 44, the side wall of the first limiting block 413 away from the compression spring 42 abuts against the second limiting block 446, which can effectively prevent the sliding block 41 from detaching from the sealing machine housing 11 under the action of the compression spring 42.

[0048] 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.
