Description

Technical Field

[0001] The present invention relates to the field of household vacuum sealing machines, and in particular to a highly hygienic vacuum sealing machine. Background Art

[0002] A vacuum sealer is a machine that places food into a bag, extracts the air from the bag, and completes the sealing process after reaching a predetermined vacuum level. With technological advancements and increased public health awareness, the size of vacuum sealers has gradually decreased, and customers prefer using small vacuum sealers to seal and preserve food at home.

[0003] The relevant vacuum sealing machine includes a shell, a workbench and a pressing mechanism. The shell is provided with a receiving slot for the opening of the packaging bag to enter. The workbench and the pressing mechanism are both arranged in the shell. When the packaging bag is inserted into the receiving slot, the workbench and the pressing mechanism are respectively located on both sides of the packaging bag. The pressing mechanism is connected to a driving mechanism, which drives the pressing mechanism to slide back and forth in the direction of approaching and moving away from the workbench. An electric heating plate is installed on the pressing mechanism. The electric heating plate is used to generate heat and press against the packaging bag, so that the opening of the packaging bag is sealed. An air pump is provided in the shell. The air pump is used to extract the air in the packaging bag so that the bag contains less air when it is sealed.

[0004] The above-mentioned related technical solutions have the following defects: when the washed food is placed in the packaging bag and sealed, the water droplets attached to the surface of the food can easily enter the receiving groove of the sealing machine with the air. The water droplets accumulate in the sealing machine and are difficult to clean. The humid environment can easily breed bacteria or attract mosquitoes, resulting in poor hygiene in the sealing machine and easy contamination of the sealed food. Summary of the Invention

[0005] In order to reduce the chance of moisture accumulating and bacteria growing in the sealing machine, the present application provides a highly hygienic vacuum sealing machine.

[0006] The present application provides a highly hygienic vacuum sealing machine that adopts the following technical solutions:

[0007] A highly hygienic vacuum sealing machine comprises an outer shell, a mounting plate, a pressing mechanism and a driving mechanism. The outer shell is provided with a receiving groove for inserting a packaging bag. The mounting plate, the pressing mechanism and the driving mechanism are installed in the outer shell. The mounting plate and the pressing mechanism are parallel to each other and are respectively installed on opposite sides of the receiving groove. The pressing mechanism is used to press on the packaging bag and seal the packaging bag. An air pump is installed on the mounting plate. The air pump is used to evacuate or inflate the internal space of the receiving groove. A water collecting box is detachably connected to the outer shell. The water collecting box is used to be inserted into the receiving groove. The water collecting box is used to collect water droplets flowing out of the packaging bag. The pressing mechanism is used to fall and press on the bottom wall of the water collecting box.

[0008] By adopting the above technical solution, a mounting plate and a pressing mechanism are provided in the outer shell, so that the pressing mechanism can slide and abut against the mounting plate. When the opening of the packaging bag is inserted into the receiving groove, the pressing mechanism can press the packaging bag and seal the packaging bag. By inserting the water collecting box into the receiving groove, after the user inserts the bag opening of the packaging bag into the receiving groove, the pressing mechanism can press the packaging bag and abut against the bottom wall of the water collecting box. When the air pump evacuates the receiving groove, the water droplets in the packaging bag flow out from the bag opening and accumulate in the water collecting box. The user can take out the water collecting box and clean the water collecting box after the sealing is completed, thereby reducing the amount of water accumulated in the receiving groove and reducing the chance of bacteria breeding in the receiving groove.

[0009] Optionally, a slide bar is installed on the mounting plate, and a matching groove is provided on the outer side wall of the water collecting box, and the slide bar is used to be slidably connected in the matching groove.

[0010] By adopting the above technical solution, by arranging a slide bar on the mounting plate, the water collecting box is slidably connected to the slide bar through the matching groove, thereby reducing the probability of the water collecting box sliding vertically in the receiving groove.

[0011] Optionally, the pressing mechanism includes a base plate, two sliding plates, an abutment frame and a heating element. The base plate is parallel to the mounting plate, and the two sliding plates are respectively mounted on two opposite side walls of the base plate. A sliding groove is provided on the mounting plate, and the sliding plate is slidably connected in the sliding groove.

The driving element is mounted on the mounting plate. The driving element is used to drive the active cam to rotate, and the active cam is used to push the inner wall of the cavity and drive the base plate to move back and forth.

[0012] By adopting the above technical solution, the substrate is connected by sliding on the mounting plate, so that the substrate can drive the abutment frame and the heating element to abut against the mounting plate. By opening a cavity on the sliding plate, the driving member drives the active convex circle to rotate in the cavity, and then the active convex circle drives the sliding plate to slide on the mounting plate, thereby achieving the effect of making the downward pressing mechanism move back and forth.

[0013] Optionally, a driven cam is rotatably connected to the mounting plate, and the driven cam and the active cam are respectively installed in the cavity of a sliding plate. A connecting rod is provided on the active cam, one end of the connecting rod is fixed on the active cam, and the other end is fixed on the driven cam. The connecting rod is used to make the active cam and the driven cam rotate synchronously.

[0014] By adopting the above technical solution, by respectively arranging an active cam and a driven cam on the two sliding plates, and arranging a connecting rod between the active cam and the driven cam, the active cam and the driven cam can rotate synchronously, and then the two sliding plates can move up and down synchronously. When the substrate slides on the mounting plate, the substrate can move parallel to the mounting plate, and then the heating element on the substrate can be pressed flatly on the packaging bag, so that the sealing performance of the packaging bag after sealing is better.

[0015] Optionally, an ultraviolet lamp is provided on a surface of the substrate close to the mounting plate, and the ultraviolet lamp is used to irradiate and disinfect the inner wall of the receiving tank.

[0016] By adopting the above technical solution and arranging an ultraviolet lamp on the substrate, the user can turn on the ultraviolet lamp after completing the sealing, so that the ultraviolet lamp can sterilize and disinfect the inner wall of the receiving groove, thereby reducing the chance of bacteria growing on the inner wall of the receiving groove.

[0017] Optionally, a sealing mechanism is detachably connected to the shell, and the sealing mechanism includes a sealing member and a cover member, the cover member and the sealing member are fixedly connected, the sealing member is elastic, the sealing member is used to be inserted into the accommodating groove, and the cover member is used to abut against the shell and cover the accommodating groove.

[0018] By adopting the above technical solution, a sealing mechanism is provided on the outer shell so that the sealing piece can be inserted into the receiving groove. When the sealing machine is idle for a long time, dust is likely to accumulate in the receiving groove. By inserting the sealing piece into the receiving groove, the chance of dust or insects entering the receiving groove can be reduced, so that the inner wall of the receiving groove can be kept clean.

[0019] Optionally, a heating resistance wire is provided on the blocking member, the heating resistance wire passes through the blocking member and extends from a side of the blocking member away from the cover member, and the heating resistance wire is used to be inserted into the accommodating groove.

[0020] By adopting the above technical solution, by arranging a heating resistance wire on the sealing member, when the sealing mechanism is inserted into the receiving groove, the heating resistance wire can be inserted into the receiving groove and generate heat, thereby allowing the heating resistance wire to dry the moisture in the receiving groove and keep the receiving groove dry.

[0021] Optionally, a connecting piece is provided on the cover piece, the connecting piece is made of a flexible material, and the connecting piece is connected to the outer side wall of the shell.

The connecting piece can fit the surface of the outer shell and cover the water collecting box, thereby reducing the chance of the water collecting box slipping out of the receiving groove when the sealing machine is moved.

[0023] In summary, the beneficial technical effects of this application are:

[0024] 1. By arranging a mounting plate and a pressing mechanism in the housing, the pressing mechanism can slide and abut against the mounting plate.

[0037] The present application is further described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] The present application embodiment discloses a highly hygienic vacuum sealer, referring to Figure 1 、 Figure 2 and Figure 3 , including a shell 1, a mounting plate 2, a pressing mechanism 3 and a driving mechanism 4. The mounting plate 2 is installed in the shell 1. A receiving groove 14 is provided on the shell 1. The receiving groove 14 is a blind groove. The receiving groove 14 is used for inserting the opening of the packaging bag. The pressing mechanism 3 is slidably connected in the shell 1. The driving mechanism 4 is installed in the shell 1 and connected to the pressing mechanism 3. The driving mechanism 4 is used to drive the pressing mechanism 3 to move back and forth. When the packaging bag is inserted into the shell 1, the packaging bag is located between the mounting plate 2 and the pressing mechanism 3. By moving the pressing mechanism 3 downward, the pressing mechanism 3 and the mounting plate 2 can clamp the opening of the packaging bag. The pressing mechanism 3 includes a heating element 34 that can generate heat through electrical energy. The heating element 34 presses on the packaging bag to achieve the effect of sealing the packaging bag.

[0040] Reference Figure 1The housing 1 includes an upper curved plate 11, a lower curved plate 12, and two end caps 13. The upper curved plate 11 is an arc-shaped plate. The upper curved plate 11 and the lower curved plate 12 can be assembled into a cylindrical structure. The receiving groove 14 is provided on the upper curved plate 11 and the lower curved plate 12. The length direction of the receiving groove 14 is parallel to the length direction of the upper curved plate 11. The end caps 13 are circular cover structures. The two end caps 13 are respectively covered at both ends of the upper curved plate 11. The end caps 13 are detachably connected to the upper curved plate 11 and the lower curved plate 12 by bolts.

[0041] Reference Figure 2 The mounting plate 2 is mounted on the lower curved plate 12, with its length parallel to that of the lower curved plate 12. An air pump 23 is mounted on the mounting plate 2, which is used to degas the packaging bag inserted into the receiving groove 14. A workbench 21 is provided on the mounting plate 2, which is a horizontal surface. The pressing mechanism 3 is used to press against the workbench 21 and seal the packaging bag.

[0042] Reference Figure 3 、 Figure 4 and Figure 5The pressing mechanism 3 also includes a base plate 31, two sliding plates 32 and an abutment frame 33. The two opposite sides of the base plate 31 are respectively connected to the sliding plates 32. The base plate 31 is perpendicular to the sliding plates 32. Two slide grooves 22 are provided on the mounting plate 2. Each sliding plate 32 is inserted into a slide groove 22. The base plate 31 is slidably connected to the mounting plate 2 through the sliding plates 32. The base plate 31 is parallel to the workbench 21 and is used to slide back and forth in the direction of approaching and moving away from the workbench 21. The abutment frame 33 is installed on the side of the base plate 31 close to the mounting plate 2. The abutment frame 33 is a frame-shaped structure and is made of an elastic material such as rubber. An air hole 331 is provided on the base plate 31. The air hole 331 is located in the middle of the abutment frame 33. The air hole 331 is connected to the air pump 23 through a pipe. The length direction of the abutment frame 33 and the heating element 34 is equal to the width of the receiving groove 14. When a packaging bag with a width smaller than the receiving groove 14 is inserted into the receiving groove 14, the length of the abutment frame 33 and the heating element 34 is greater than the width of the packaging bag, thereby enabling the abutment frame 33 and the heating element 34 to press on the packaging bag. The heating element 34 is installed on the substrate 31 at a position close to the opening of the receiving groove 14, and the abutment frame 33 is located on the substrate 31 at a position away from the opening of the receiving groove 14. When the substrate 31 moves downward, the abutment frame 33 gradually abuts on the packaging bag, reducing the cross-sectional area of ​​the opening of the packaging bag. The air pump 23 continues to pump air to extract the air in the packaging bag. The abutment frame 33 continues to fall, causing the abutment frame 33 to abut on the mounting plate 2 and deform. At this time, the heating element 34 can press the packaging bag on the mounting plate 2, completing the work of pumping air and sealing. The air pump 23 can inflate the containing tank 14 through the pipe and the air hole 331, so that the gas injected by the air pump 23 can blow out the solid impurities remaining in the containing tank 14, thereby keeping the workbench 21 and the pressing mechanism 3 clean and improving the hygiene of the packaging bag processing.

[0043] Reference Figure 4 and Figure 5The driving mechanism 4 includes a driving member 41, an active cam 42, a driven cam 43 and a connecting rod 44. The driving member 41 is configured as a motor, and the motor housing is fixed to the side of the mounting plate 2 away from the pressing mechanism 3. The output shaft of the motor is coaxially connected to the active cam 42, and the driving member 41 can drive the active cam 42 to rotate. A cavity 321 is provided on the sliding plate 32. The active cam 42 is installed in the cavity 321 on one sliding plate 32, and the driven cam 43 is installed in the cavity 321 on the other sliding plate 32. The driven cam 43 is rotatably connected to the side of the mounting plate 2 away from the pressing mechanism 3. The rotating axes of the active cam 42 and the driven cam 43 coincide when they rotate on the mounting plate 2. When the active cam 42 rotates, different positions on the active cam 42 press against the inner wall of the cavity 321, thereby driving the sliding plate 32 and the base plate 31 to move. The connecting rod 44 is arranged on the side of the mounting plate 2 away from the pressing mechanism 3. One end of the connecting rod 44 is connected to the active cam 42, and the other end is connected to the driven cam 43. During the rotation of the active cam 42, the length direction of the connecting rod 44 is always parallel to the mounting plate 2. The connecting rod 44 is used to connect the active cam 42 and the driven cam 43, thereby allowing the driven cam 43 to be stationary relative to the active cam 42, thereby allowing the two sliding plates 32 on the base plate 31 to move the same distance at the same time, and ultimately allowing the base plate 31 to always move parallel to the mounting plate 2. When the base plate 31 presses down on the packaging bag, the heating element 34 on the base plate 31 can be pressed flat on the packaging bag, so that the sealing effect of the packaging bag is better.

[0044] Reference Figure 1 and Figure 6 The outer shell 1 is detachably connected to a water collection box 5. The water collection box 5 is a rectangular box structure and is used to be inserted into the receiving tank 14. A sink is provided on the mounting plate 2, the bottom surface of which forms a workbench 21. The side walls of the sink fit on the outer wall of the water collection box 5. Slide bars 211 are provided on the side walls of the sink. The length of the slide bars 211 is perpendicular to the sliding direction of the pressing mechanism 3 on the mounting plate 2. A mating groove 51 is provided on the outer wall of the water collection box 5. The slide bars 211 are used to insert into the mating groove 51, thereby reducing the probability of the water collection box 5 sliding vertically in the receiving tank 14. When the water collection box 5 is inserted into the receiving tank 14, the outer bottom surface of the water collection box 5 fits on the workbench 21, and the opening of the water collection box 5 faces the pressing mechanism 3. When the packaging bag is inserted into the receiving tank 14, the pressing mechanism 3 can fall and press on the bottom of the water collection box 5. When water droplets adhere to the surface of the items contained in the packaging bag, the water droplets are easily drawn into the receiving groove 14 along with the air. By providing a water collection box 5 in the receiving groove 14, the water droplets in the packaging bag can be accumulated in the water collection box 5, thereby reducing the chance of water droplets adhering to the receiving groove 14 and the chance of bacteria growing on the inner wall of the receiving groove 14. After the sealing work is completed, the user can remove the water collection box 5 and pour out the water in the water collection box 5.

[0045] Reference Figure 4An ultraviolet lamp 311 is provided on one side of the substrate 31 close to the mounting plate 2 , and the ultraviolet lamp 311 is used to irradiate the inner wall of the receiving groove 14 , thereby reducing the probability of bacteria growing on the inner wall of the receiving groove 14 .

[0046] The implementation principle of the embodiment of the present application is as follows: by arranging a mounting plate 2 and a pressing mechanism 3 in the outer shell 1, the user can insert the opening of the packaging bag into the receiving groove 14, so that the pressing mechanism 3 and the mounting plate 2 clamp the packaging bag, and then the heating element 34 generates high temperature and presses on the packaging bag, thereby achieving the effect of sealing the packaging bag; by arranging an air pump 23 on the mounting plate 2, the air pump 23 is connected to the air hole 331 through a pipe, so that the air pump 23 can extract the air in the packaging bag to achieve the effect of vacuum sealing; by inserting a water collecting box 5 in the receiving groove 14, the water droplets in the packaging bag can accumulate in the water collecting box 5, thereby reducing the amount of water droplets accumulated on the inner wall of the receiving groove 14, which can reduce the chance of bacteria growing on the inner wall of the receiving groove 14, improve the hygiene of the sealed packaging bag, and reduce the chance of bacteria adhering to the surface of food in the vacuum-sealed packaging bag.

[0047] Example 2

[0048] This application discloses a highly hygienic vacuum sealing machine, referring to Figure 7 On the basis of Example 1, a sealing mechanism 6 is detachably connected to the housing 1. The sealing mechanism 6 includes a sealing member 61, a cover member 62, and a heating resistor 63. The sealing member 61 is connected to the cover member 62. The cross-sectional area of ​​the sealing member 61 is smaller than that of the cover member 62. The sealing member 61 is made of an elastic material such as silicone. The sealing member 61 is used to be inserted into the receiving groove 14, and the cover member 62 is used to fit the housing 1 and cover the opening of the receiving groove 14. After the user completes the sealing, the sealing mechanism 6 can be installed on the housing 1, thereby reducing the chance of dust and insects entering the receiving groove 14 and improving hygiene. The heating resistor 63 is set through the sealing member 61 and the cover member 62. The elastic material buries the heating resistor 63 and solidifies to form the sealing member 61. The end of the heating resistance wire 63 extends from the end of the sealing member 61 away from the sealing member 62. The heating resistance wire 63 is used to be inserted into the receiving groove 14. When the user vacuum seals the cleaned food, water droplets remain in the receiving groove 14 and the water collecting box 5. The heating resistance wire 63 can accelerate the evaporation rate of liquid water by generating heat, thereby keeping the receiving groove 14 dry and reducing the chance of bacterial growth. The high temperature generated by the heating resistance wire 63 can sterilize and disinfect the inner wall of the receiving groove 14, thereby improving the hygiene of the sealing machine.

[0049] Reference Figure 8 and Figure 9The cover member 62 is equipped with a battery, a controller 7, and a pressure sensor 8. The battery is used to power the heating resistor 63. The controller 7 is used to control the operation of the heating resistor 63. The pressure sensor 8 is in communication with the controller 7. The pressure sensor 8 is arranged on the surface of the cover member 62 connected to one side of the blocking member 61. When the blocking mechanism 6 is installed on the housing 1, the pressure sensor 8 is clamped by the cover member 62 and the housing 1 and transmits an electrical signal. The controller 7 receives the electrical signal and controls the operation of the heating resistor 63, thereby causing the heating resistor 63 to sterilize and dry the inner wall of the receiving tank 14. The controller 7 is equipped with a timing module that can periodically cut off the power to the heating resistor 63, thereby reducing the power consumption of the heating resistor 63. In other embodiments, a wireless communication module may be provided on the controller 7, and the wireless communication module includes a signal transmitting end and a signal receiving end. The signal transmitting end is communicatively connected to the controller 7, and the signal receiving end is communicatively connected to the air pump 23. After receiving the electrical signal from the pressure sensor 8, the controller 7 can control the air pump 23 to start and pump air, so that the water vapor generated by the heating resistor 63 in the receiving tank 14 can be pumped out of the receiving tank 14 through the air pump 23.

[0050] Reference Figure 8 The cover 62 is provided with a connector 64, which is made of a flexible material and has a rectangular structure. One side of the connector 64 is connected to the cover 62, and the other side is connected to the housing 1. The connector 64 is used to install the blocking mechanism 6 on the housing 1.

[0051] Reference Figure 8 The connector 64 is provided with a plurality of snap fasteners 641. The snap fasteners 641 are fixed to the housing 1, and the female snap fasteners 641 are fixed to the edges of the connector 64. The snap fasteners 641 allow the connector 64 to be detachably connected to the housing 1, further facilitating the user's removal of the sealing mechanism 6 and the water collection box 5. When the sealing mechanism 6 is inserted into the receiving slot 14, the edge of the connector 64 can be connected to the housing 1, thereby covering the receiving slot 14 and reducing the chance of the water collection box 5 slipping out of the receiving slot 14.

[0052] The implementation principle of the embodiment of the present application is: by arranging a sealing mechanism 6 on the outer shell 1, the sealing mechanism 6 can cover the receiving groove 14 on the outer shell 1, further reducing the chance of dust accumulation and insect entry in the receiving groove 14, and improving the hygiene of the sealing machine.

[0053] In other embodiments, the blocking member 61 is provided with an opening, and a cover is detachably connected to the blocking member 61, which is used to cover the opening of the blocking member 61. The cover has a hole, and a volatile disinfectant or insect repellent is placed in the opening of the blocking member 61. When storing the sealer, the user can insert the blocking member 61 into the receiving groove 14, further reducing the chance of bacterial growth or mosquito intrusion inside the sealer, thereby keeping the interior of the sealer clean and hygienic.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
