DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0034] It should be understood that, in the description of the present application, the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, that is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.

[0035] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0036] like Figure 1-Figure 4 As shown, the washable heating rod 100 of some embodiments of the present invention comprises a main body 1, a heating wire 2, an upper cover 3, a high temperature adhesive tape 4 and two sealing rings 5. The upper cover 3 is removed to facilitate maintenance and repair of the heating wire 2 installed in the main body 1, and the interior of the main body 1 is sealed by installing the upper cover 3 and cooperating with the high temperature adhesive tape 4 and the two sealing rings 5, so that the structure of the main body 1 has a sealing effect, ensuring that the exterior of the main body 1 is easy to clean.

[0037] The main body 1 has a receiving cavity 11 inside, a first opening 12 at the upper part of the main body 1, and two conductive column holes 13 at the lower part of the main body 1. The receiving cavity 11 is connected with the first opening 12 and the two conductive column holes 13 respectively. In this way, the heat generated by the heating wire 2 is dissipated upward through the first opening 12, which is conducive to heating and sealing the bag opening of the vacuum bag; the conductive column holes 13 are used to install the conductive column 400 so that the heating wire 2 can be connected to the power supply.

[0038] The heating wire 2 is installed in the accommodating cavity 11 , so that the installation structure of the heating wire 2 is compact, and the heating wire 2 is kept clean during use by sealing the accommodating cavity 11 .

[0039] The upper cover 3 is disposed on the upper part of the main body 1. For example, the upper cover 3 and the main body 1 are connected by snap-fitting, screwing or bonding to ensure a compact installation structure between the two. The upper cover 3 has a second opening 31 arranged opposite to the first opening 12. In this way, the heat generated by the heating wire 2 is dissipated from the second opening 31 of the upper cover 3, which is conducive to heating and sealing the bag opening of the vacuum bag.

[0040] The lower surface of the high temperature tape 4 is wrapped around the heating wire 2 and used to seal the first opening 12, and the upper surface of the high temperature tape 4 is used to seal the second opening 31. By providing the high temperature tape 4, on the one hand, it can withstand high temperatures and conduct heat, which is conducive to heating and sealing the bag opening of the vacuum bag placed on the high temperature tape 4, and on the other hand, the high temperature tape 4 seals the first opening 12 and the second opening 31, so that the accommodating cavity 11 in the main body 1 has a waterproof effect.

[0041] The two sealing rings 5 ​​are installed in the conductive column holes 13 in a one-to-one correspondence. The conductive column holes 13 are used to install the conductive column 400. When the upper end of the conductive column 400 passes through the sealing ring 5 and is electrically connected to the heating wire 2, the accommodating cavity 11 is in a sealed state. At this time, during the heating and sealing process of the bag opening of the vacuum bag, no contaminants will enter the interior of the accommodating cavity 11, so as to ensure the cleanliness of the internal structure.

[0042] Based on the above-mentioned structural setting, by installing the heating wire 2 in the accommodating cavity 11 of the main body 1, the heat generated by the heating wire 2 is conducted to the bag opening of the vacuum bag placed on the high-temperature tape 4 through the first opening 12 and the second opening 31, and the bag opening of the vacuum bag is sealed. At this time, the upper end of the conductive column 400 passes through the sealing ring 5 and is electrically connected to the heating wire 2 so that the accommodating cavity 11 is in a sealed state, and no contaminants enter the interior of the accommodating cavity 11 to ensure the cleanliness of the internal structure. In addition, by removing the upper cover 3, it is convenient to maintain and inspect the heating wire 2 installed in the main body 1, so that the structure of the washable heating rod 100 has both disassembly and sealing effects, thereby achieving convenient cleaning and maintenance.

[0043] like Figure 2As shown, in some embodiments, the two ends of the main body 1 have third openings 14, and the two third openings 14 are both connected to the accommodating cavity 11. The two ends of the upper cover 3 extend downward to form side covers 32, and the two side covers 32 are respectively arranged on the two third openings 14, and a sealing strip is arranged between the side covers 32 and the main body 1. In this way, the installation and removal of the heating wire 2 are more convenient through the third openings 14, and the side covers 32 formed by the two ends of the upper cover 3 extending downward can keep the third openings 14 sealed.

[0044] like Figure 3 As shown, in some embodiments, the lower part of the main body 1 has a fourth opening 15, and the fourth opening 15 is arranged between the two conductive column holes 13. The washable heating rod 100 includes a bottom shell 6, which is installed at the bottom of the main body 1 and is used to seal the fourth opening 15. The bottom shell 6 has two first through holes 61, and the two first through holes 61 are arranged in a one-to-one correspondence with the two conductive column holes 13. The arrangement of the fourth opening 15 is conducive to reducing the structural weight of the main body 1, and is conducive to the heat dissipation of the main body 1, so as to avoid the main body 1 from being too high in temperature after being heated by the heating wire 2. The fourth opening 15 can be sealed by arranging the bottom shell 6. When in use, the conductive column 400 can pass through the first through hole 61.

[0045] like Figure 3 As shown, in some embodiments, the washable heating rod 100 includes a sealing pad 7, which is disposed between the main body 1 and the bottom shell 6. The sealing pad 7 has two second through holes 71, and the two second through holes 71 are disposed one-to-one with the two conductive column holes 13. The sealing effect of the fourth opening 15 can be further improved by providing the sealing pad 7. When in use, the conductive column 400 can pass through the first through hole 71.

[0046] like Figure 3 As shown, in some embodiments, the lower part of the main body 1 has a plurality of threaded holes 16, and the threaded holes 16 are located on both sides of the fourth opening 15. The washable heating rod 100 includes a plurality of screws, and the screws pass through the bottom shell 6 and the sealing gasket 7 and are installed in the threaded holes 16. The bottom shell 6 and the sealing gasket 7 are conveniently installed and removed by the screws.

[0047] Further, in some embodiments, the lower part of the main body 1 has a screw hole seat 17, the screw hole seat 17 is located in the middle of the fourth opening 15, and the screw passes through the bottom shell 6 and the sealing gasket 7 and is installed in the screw hole seat 17. The bottom shell 6 and the sealing gasket 7 are evenly stressed, and the bottom shell 6 and the sealing gasket 7 are installed firmly at the lower part of the main body 1.

[0048] Exemplarily, in some embodiments, the outer edge of the bottom of the main body 1 is flush with the outer edge of the bottom shell 6, and the outer edge of the sealing gasket 7 does not exceed the outer edge of the bottom shell 6. In this way, the overall structure of the washable heating rod 100 is regular.

[0049] like Figure 3 As shown, in some embodiments, the washable heating rod 100 includes a conductive sheet 9, which is disposed in the accommodating cavity 11, the upper surface of the conductive sheet is electrically connected to the heating wire 2, the lower surface of the conductive sheet is sealed and covered on the upper part of the conductive column hole 13, and the conductive column 400 is electrically connected to the heating wire 2 through the conductive sheet. In this way, the conductive column hole 13 can be sealed by the conductive sheet 9, so that the heating wire 2 will not enter water during the washing process of the washable heating rod 100.

[0050] In some embodiments, the washable heating rod 100 includes a heat preservation sheet installed between the high temperature tape 4 and the heating wire 2. Specifically, the heat preservation sheet is made of mica, which can slow down the speed at which the heat generated by the heating wire 2 is dissipated through the main body 1, thereby achieving a better heat sealing effect on the vacuum bag.

[0051] like Figure 4 As shown, in some embodiments, the washable heating rod 100 includes a bag clamp 8, which is mounted on the side wall of the main body 1. The bag clamp 8 includes a base 81 and an elastic sheet 82 integrally formed on the base 81. The base 81 has a groove 83, and the groove 83 is correspondingly arranged below the elastic sheet 82. The elastic sheet 82 is used to clamp the bag opening of the vacuum bag. By setting the bag clamp 8, the position of the vacuum bag can be fixed, so that the bag opening of the vacuum bag can be heat-sealed regularly.

[0052] like Figure 5 As shown, some other embodiments of the vacuum machine of the present invention include a machine case 200, a case cover 300, two conductive columns 400 and a heating rod 100 that can be washed and cleaned.

[0053] The housing 200 has a vacuum chamber 210 therein.

[0054] The box cover 300 is installed on the chassis 200 , and the box cover 300 is used to open or close the vacuum chamber 210 .

[0055] The food tray 500 is disposed in the vacuum chamber 210 .

[0056] Two conductive posts 400 are mounted on the chassis 200 , and upper ends of the conductive posts 400 extend through the food tray 500 and into the vacuum chamber 210 .

[0057] The washable heating rod 100 is disposed in the vacuum chamber 210 , and the two conductive posts 400 are installed in the two conductive post holes 13 of the washable heating rod 100 in a one-to-one correspondence and are electrically connected to the heating wire 2 of the washable heating rod 100 .

[0058] When in use, open the box cover 300 and place the vacuum bag in the vacuum chamber 210, fix the bag opening of the vacuum bag by the bag clamp 8 of the washable heating rod 100, close the box cover 300 and open the washable heating rod 100 to heat and seal the bag opening of the vacuum bag.

[0059] Based on the above structural setting, the structure of the vacuum machine has both disassembly and sealing effects, making cleaning and maintenance convenient.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
