Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As shown in fig. 1 to 5, the sealing device 10 for thermoplastic garbage bag of the present invention comprises a base 11, a heating element 12, a fastening element 13 and a wiring element 14. The base 11 is used to support the heating member 12. The base 11 includes a first end surface on which at least two holes are provided. The heating member 12 is disposed on the first end surface and at least two ends of the heating member 12 are located at positions of at least two holes. The wiring members 14 are provided on the base 11 at positions of at least two holes. And at least two fastening members 13 corresponding to the at least two holes one by one, one ends of the fastening members 13 being disposed at the first end surface and fixing the heating member 12, and the other ends of the fastening members 13 being inserted into the holes of the base 11 corresponding to the fastening members 13.
The material of the base 11 is an insulating material such as asbestos or artificial stone. In this embodiment, the material of the base 11 is asbestos. The shape of the susceptor 11 is not limited as long as the susceptor includes a support surface 111 for supporting the heater 12. In the present embodiment, the base 11 has a rectangular parallelepiped shape, and the length and width of the rectangular parallelepiped shape are slightly larger than those of the heating member 12, so as to facilitate the arrangement of the heating member 12 thereon and save space. The base 11 includes a first end surface and a second end surface disposed opposite to the first end surface. The first end surface of the base 11 is used for supporting the heating element 12, and the second end surface of the base 11 is fixed on a mounting seat of the intelligent garbage can. Because the base 11 is made of an insulating heat-insulating material, the high temperature generated by the heating element 12 is prevented from being transmitted to other elements of the intelligent garbage can through the base 11, so that the other elements of the intelligent garbage can are prevented from being thermally damaged. The thickness of the susceptor 11 ranges from 5 mm to 10 mm, and the thickness prevents heat generated from the heating member 12 above the susceptor 11 from being transferred to other components. In the present embodiment, the thickness of the base 11 is 6 mm.
The base 11 is provided with at least two holes on a first end surface thereof. In the present embodiment, the number of holes on the base 11 is 2, and the two holes of the base 11 are through holes that penetrate the first end surface and the second end surface, respectively. The two holes are located at both ends of the first end surface of the susceptor 11, and the positions of the two holes correspond one-to-one to the positions of both end portions of the heating member 12. Specifically, both end portions of the heating member 12 are fixed above the two holes by fasteners 13.
The first end face of the base 11 includes a supporting face 111 located in a central region of the first end face, two fitting faces 113 located at both ends of the first end face, and two connecting faces 112 connecting the supporting face 111 and the two fitting faces 113 at both sides thereof. The supporting surface 111 and the fitting surface 113 are planes parallel to each other. The attachment surface 112 is an inclined surface inclined with respect to the support surface 111 and the fitting surface 113. The two through holes of the base 11 are respectively located on the two fitting surfaces 113 of the base 11. The supporting surface 111 of the base 11 is used for supporting the middle section of the heating element 12, and the two mounting surfaces 113 of the base 11 are used for fixing the two ends of the heating element 12. The supporting surface 111 and the fitting surface 113 of the base 11 have a height difference h therebetween. The height difference h should be greater than the height difference between the top of the fastening member 13 and the assembling surface 113, so as to ensure that the top of the fastening member 13 is not higher than the supporting surface 111 of the base 11, so as to avoid that the pressing rod pressing the garbage bag to the heating member 12 is jacked up when the garbage bag thermoplastic sealing device 10 is in use under the condition that the top of the fastening member 13 is higher than the supporting surface 111 of the base 11, and the garbage bag cannot be pressed on the heating member 12, so that the sealing effect of the garbage bag is poor. The connecting surface 112 of the base 11 is inclined with respect to the supporting surface 111 and the assembling surface 113, and because of the height difference h between the supporting surface 111 and the assembling surface 113, the inclined connecting surface 112 helps the heating element 12 to be attached to the connecting surface 112, so that the transition from the supporting surface 111 to the assembling surface 113 is smoothly performed, the suspension and excessive bending of the heating element 12 are avoided, and the service life of the heating element 12 is longer. Alternatively, at least one connecting surface 112 is provided with an elongated limiting groove which extends from the end of the connecting surface 112 adjoining the supporting surface 111 to the end of the connecting surface 112 adjoining the mounting surface 113, or the limiting groove may be provided only in a partial section of the connecting surface 112 in the direction from the supporting surface 111 to the mounting surface 113. The part of the heating member 12 on the connecting surface 112 is arranged in the limiting groove, so that the heating member 12 is fixed and limited, and the phenomenon that the heating member 12 shakes to influence the sealing effect of the heating member 12 on the garbage bag is avoided. Optionally, at least one of the connection surfaces 112 is provided with a limiting rib comprising two elongated ribs arranged parallel to and spaced apart from each other. The two elongate ribs extend from the end of the connecting surface 112 adjoining the supporting surface 111 to the end of the connecting surface 112 adjoining the mounting surface 113, or the ribs are arranged only in a partial section of the connecting surface 112 in the direction from the supporting surface 111 to the mounting surface 113. The portion of the heating member 12 on the connection surface 112 is disposed between the two ribs. Two sand grips can be fixed and spacing heating member 12 equally, have avoided heating member 12 to rock, influence heating member 12 and to the garbage bag seal the effect.
The heating member 12 is made of a heating wire, specifically, a resistance wire, which is capable of efficiently converting electric energy into thermal energy. The heating members 12 are fixed to both ends of the base 11 by fasteners 13, so that the heating wires are tensioned. The intermediate section of the heating member 12 is closely attached to the supporting surface 111 of the base 11 and supported by the supporting surface 111. The part of the heating element 12 on the connecting surface 112 of the base 11 is tightly attached to the two connecting surfaces 112 of the base 11 and is limited by the limiting groove or the limiting convex strip on the connecting surface 112, so as to keep the stability of the heating element 12. Both ends of the heating member 12 are positioned on the mounting surface 113 of the base 11 and fixed at the mounting surface 113. The heating member 12 may be a straight line as a whole, or the end of the heating member 12 may be wound around the stem portion 132 of the fastening member 13 at least once to be more firmly fixed by the fastening member 13. In this embodiment, the central portion of the heating element 12 is straight, the ends wrap around the stem portion 132 of the fastener 13, and the ends are bent into a generally circular shape.
The number of the fasteners 13 is at least two, and the positions of the fasteners 13 correspond to the positions of the through holes on the base 11 one by one. In the present embodiment, the fasteners 13 are two, and each of the two fasteners 13 includes a cap portion 131 and a stem portion 132. The cap 131 includes a fastening surface 133 disposed opposite the mounting surface 113 of the base 11. The cap 131 is flat or spherical, and thus, the fastening surface 133 of the cap 131 may be polygonal or circular. The end of the rod 132 is disposed at the center of the fastening surface 133 of the cap 131. The rod portion 132 extends perpendicularly to the fastening surface 133 of the cap portion 131, and the two fastening members 13 press-fix both end portions of the heating member 12 between the fastening surface 133 of the cap portion 131 and the fitting surface 113 of the base 11, respectively, with the rod portion 132 inserted into the through hole of the base 11. The fastening surface 133 of the cap 131 applies a compressive force to the heating member 12. In the present embodiment, the fastener 13 is a rivet or a combination of a screw and a nut. The fastener 13 is made of brass, phosphor bronze or stainless steel. In the present embodiment, the material of the fastener 13 is brass. The material of the fastener 13 is such that it has the advantage of low thermal and electrical conductivity. The two fasteners 13 may be identical in construction, i.e., both are rivets, both are a combination of screws and nuts. The two fasteners 13 may also be of different construction, i.e. one fastener 13 being a rivet and the other being a screw and nut combination.
The wiring piece 14 can be electrified to the heating member 12, and in use, the pressing rod of the intelligent garbage bin presses the garbage bag on the middle section of the heating member 12. The heating member 12 after the energization generates heat, and the temperature of the heating member 12 rises to a temperature capable of melting the garbage bag. The garbage bag is melted by the high temperature of the heating element 12, thereby realizing that the garbage bag is sealed. Specifically, the temperature range of the heating member 12 after the temperature rise is 200 ℃ to 400 ℃. In this embodiment, the temperature of heating element 12 after the temperature rise is 300 ℃. The wiring member 14 is electrically connected to an external power supply line to energize the heating member 12. In this embodiment, the wiring member 14 is two wiring terminals each having a through hole formed thereon.
In the present embodiment, the connection terminals are disposed at the openings of the two through holes of the base 11 at the second end surface, the shaft portions 132 of the fasteners 13 pass through the through holes of the base 11 and extend to the outside of the through holes of the base 11, and the shaft portions 132 of the fasteners 13 further extend through the through holes of the connection terminals. In this case, the fastener 13 is a rivet or a combination of a screw and a nut. The rivet can fasten the heating member 12 at the first end surface of the base 11 by its own properties. In the case where the fastener 13 is a combination of a screw and a nut, the shank 132 of the fastener 13 further passes through the through-hole of the nut after passing through the through-hole of the connection terminal. The nut is tightened onto the shank 132 of the fastener 13 in a direction toward the second end surface of the base 11, such that the cap 131 of the fastener 13 is compressed in a direction toward the first end surface of the base 11 until the cap 131 secures the heating element 12 to the first end surface of the base 11. The nut thus cooperates with the screw to fasten the heating element 12 to the mounting surface 113. At the second end surface of the base 11, the nut, the terminal 14 and the base 11 are firmly fixed together, and at the fitting surface 113 of the base 11, the fastening surface 133 of the fastening member 13 presses the heating member 12.
The position of the wiring piece 14 is arranged at the second end face of the base 11, so that the connection point of the wiring piece 14 and the external power supply lead is far away from the heating element 12, the safety problem caused by the failure of the insulating layer of the external power supply lead due to the overheating of the external power supply lead is avoided, and the safety of the thermoplastic sealing device 10 for the garbage bag is improved. And the fasteners 13 are made of a material with low thermal conductivity, further preventing the heat generated by the heating member 12 from being conducted to external power supply lines and other components in contact with the base 11. Since only the cap portion 131 of the fastener 13 is accommodated in the through hole of the base 11 at the fitting surface 113 of the first end surface of the base 11, the height difference h between the supporting surface 111 of the base 11 and the fitting surface 113 should be larger than the height of the cap portion 131 of the fastener 13 (in this case, the height of the heating member 12 is ignored), which ensures: the top of the fastening member 13 is not higher than the supporting surface 111 of the base 11, so as to avoid that the pressing rod pressing the garbage bag to the heating member 12 is jacked up by the top of the fastening member 13, the garbage bag cannot be pressed on the heating member 12, and further the sealing effect of the garbage bag is poor.
The working principle of the thermoplastic sealing device 10 for the garbage bag of the embodiment is as follows: the wiring member 14 is electrically connected to an external power supply line, and the electric current of the wiring member 14 is transmitted to the heating member 12 through the fastening member 13, so that the heating member 12 generates heat to seal the garbage bag located above the heating member 12.
The thermoplastic sealing device 10 for the garbage bag of the embodiment has the advantages that: the first fastener 13 is selected from a rivet or a combination of a screw and a nut, so that the heating element 12 can be firmly fixed on the first end surface of the base 11, and the structure is simple and the manufacturing process is simple; secondly, the material of the fastening piece 13 is selected from materials with low thermal conductivity and high electrical conductivity, such as brass, phosphor bronze or stainless steel, so that the fastening piece 13 can well transmit the current of the wiring piece 14 to the heating piece 12, meanwhile, the fastening piece 13 does not generate large heat, damage to other elements of the intelligent garbage can caused by overheating of the second end face of the base 11 is avoided, and the safety of the thermoplastic sealing device 10 for the garbage bag is improved; thirdly, the wiring piece 14 is located at the second end face of the base 11, so that the connection point of the wiring piece 14 and the external power supply lead is far away from the heating element 12, thereby avoiding the safety problem caused by the failure of the insulating layer of the external power supply lead due to the overheating of the external power supply lead and improving the safety of the thermoplastic sealing device 10 for the garbage bag.
Referring to fig. 6, another embodiment of the present invention provides a sealing device 10 for thermoplastic garbage bag, wherein a wire connecting member 14 is disposed at an opening of the through hole of the first end surface of the base 11. That is, two connection terminals are respectively located between the two mounting faces 113 of the base 11 and the two ends of the heating member 12. At this time, there is no contact resistance between the connection terminal and the heating member 12, increasing the reliability of the electrical connection. Because the wiring terminal and the heating member 12 are both far away from the second end surface of the base 11, when a large current is conducted to the heating member 12, no heating phenomenon occurs at the second end surface of the base 11, and no thermal damage is caused to other elements of the intelligent garbage can which are in contact with the second end surface of the base 11. The fasteners 13 may be rivets, screws, combinations of screws and nuts. When the fastening member 13 is only a screw, the through-hole of the base 11 is formed with an internal thread which is engaged with the external thread of the screw, and the external thread of the screw and the internal thread of the through-hole of the base 11 are engaged with each other, so that the heating member 12 can be firmly fixed to the mounting surface 113 of the base 11.
The working principle of the thermoplastic sealing device 10 for the garbage bag of the embodiment is as follows: the wiring member 14 is electrically connected to an external power supply line, and the current of the wiring member 14 is directly transmitted to the heating member 12, so that the heating member 12 generates heat to seal the garbage bag located above the heating member 12.
The thermoplastic sealing device 10 for the garbage bag has the advantages that: firstly, the fastening member 13 can be a rivet, a screw or a combination of the screw and the nut, so that the heating member 12 can be firmly fixed on the first end surface of the base 11, the structure is simple, and the manufacturing process is simple; second, there is no contact resistance between the wiring member 14 and the heating member 12, increasing the reliability of the electrical connection; thirdly, because the wiring member 14 and the heating member 12 are both far away from the second end surface of the base 11, when a large current is applied to the heating member 12, no heat is generated at the second end surface of the base 11, and no heat damage is generated to other elements of the intelligent trash can contacting the second end surface of the base 11.
Another embodiment of the present invention provides a sealing device 10 for thermoplastic garbage bag, wherein the wiring member 14 is disposed on the mounting surface 113 of the first end surface of the base 11, and the hole on the base 11 is a blind hole with an internal thread. In this case, the fastener 13 may be a screw. The external thread of the screw cooperates with the internal thread of the blind hole to fasten the heating element 12 to the mounting surface 113.
The working principle of the thermoplastic sealing device 10 for the garbage bag of the embodiment is as follows: the wiring member 14 is electrically connected to an external power supply line, and the current of the wiring member 14 is directly transmitted to the heating member 12, so that the heating member 12 generates heat to seal the garbage bag located above the heating member 12.
The thermoplastic sealing device 10 for the garbage bag has the advantages that: the first fastener 13 is a screw and is matched with the internal thread in the blind hole of the base, so that the heating element 12 can be firmly fixed on the first end surface of the base 11, and the structure is simple and the manufacturing process is simple; secondly, there is no contact resistance between the wiring member 14 and the heating member 12, which increases the reliability of the electrical connection; thirdly, because the wiring member 14 and the heating member 12 are both far away from the second end surface of the base 11, when a large current is applied to the heating member 12, no heat is generated at the second end surface of the base 11, and no heat damage is generated to other elements of the intelligent trash can contacting the second end surface of the base 11.
Referring to fig. 7, another embodiment of the present invention provides a sealing device 10 for thermoplastic garbage bag, wherein a first end surface of a base 11 is a plane, two ends of the base are formed with counter bores for receiving fasteners 13, and a wire connecting member 14 is disposed at a second end surface of the base 11. The area of the first end face of the base 11 adjacent to the counter bore may be formed with a transition groove, and the heating element 12 is transited from the first end face of the base 11 to the counter bore through the transition groove, so that the wear caused by excessive bending of the heating element 12 is avoided, and the service life is short. The counter bore is a through hole and has a large diameter portion whose inner diameter is matched with the outer diameter of the cap portion 131 of the fastener 13 so that the cap portion 131 can be accommodated in the large diameter portion, and a small diameter portion whose inner diameter is matched with the outer diameter of the shank portion 132 of the fastener 13 so that the shank portion 132 can be accommodated in the small diameter portion. The large diameter portion has a depth d. At this time, the depth d of the large diameter portion should be greater than the height of the cap portion 131 of the fastening member 13, so that the top of the fastening member 13 is completely embedded into the counter bore and does not protrude out of the first end surface of the base 11, thereby preventing the pressing rod pressing the garbage bag to the heating member 12 from being jacked up by the fastening member 13, and preventing the garbage bag from being pressed onto the heating member 12, and further preventing the sealing effect of the garbage bag from being poor. The fasteners 13 may be rivets or a combination of screws and nuts.
The thermoplastic sealing device 10 for the garbage bag has the advantages that: the holes in the base 11 are counter bored holes, which are easy to machine and further simplify the structure and the manufacturing process.

The counterbore has a large diameter portion and a small diameter portion and a stepped surface between the large diameter portion and the small diameter portion, which in this case is a mounting surface 113 of the first end surface of the base 11.
