Description

Technical Field

[0001] The utility model relates to the technical field of laminated paper cups, in particular to a laminated paper cup structure with a heat-insulating function. Background Art

[0002] Paper cup is a kind of paper container made by mechanically processing and gluing base paper (white cardboard) made of chemical wood pulp. It has a cup-shaped appearance. Paper cups are divided into single-sided PE coated paper cups and double-sided PE coated paper cups. Single-sided PE coated paper cups.

[0003] After searching, Chinese utility model patent CN219030459U discloses a laminated paper cup structure with heat preservation function, including a handle, a cover body, and a connecting piece. The bottom of the handle is provided with a cover body, and the cover body is threadedly connected to the connecting piece. The interior of the connecting piece is provided with a heat preservation cup body, the interior of the heat preservation cup body is provided with a heating layer, and the interior of the heating layer is provided with a laminated paper cup body. The bottom of the laminated paper cup body is connected to a supporting plate, and the bottom of the supporting plate is installed with a connecting column. The bottom of the laminated paper cup body of the utility model contacts the supporting plate, and the interior of the laminated paper cup body is filled with water. Gravity causes the supporting plate to drive the connecting column to descend, and the connecting column squeezes the reset spring, so that the connecting plate at the bottom of the connecting column presses the switch. When the switch is turned on, it drives the heating layer to heat and keep the laminated paper cup body warm, so that the heat preservation performance is better. When there is no water in the laminated paper cup body, the reset spring drives the laminated paper cup body upward, the connecting plate leaves the switch, and the heating layer stops working to avoid waterless heat preservation.

[0004] When the existing device is in use, the following situation may occur: the interior of the laminated paper cup body is filled with water, and gravity causes the load-bearing plate to drive the connecting column to descend. The connecting column squeezes the reset spring, causing the connecting plate at the bottom of the connecting column to press the switch. The switch is turned on and drives the heating layer to heat and keep the laminated paper cup body warm. In other words, the device must be filled with water before the connecting plate at the bottom of the connecting column can press the switch. When the water volume is insufficient to turn on the switch, heating cannot be achieved. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a laminated paper cup structure with a heat preservation function, wherein the heat preservation function is activated under a certain amount of water.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A laminated paper cup structure with a heat-insulating function comprises: a heat-insulating device, a heat-insulating cover mounted on the heat-insulating device, and a laminated paper cup disposed between the heat-insulating cover and the heat-insulating device; the heat-insulating device comprises a heat-insulating shell, a plug mounted at the bottom of the heat-insulating shell, a gravity sensing device connected to a wire of the plug, a current limiting device connected to the gravity sensing device, and a heat-insulating layer connected to the current limiting device; the heat-insulating layer is disposed within the heat-insulating shell.

[0008] Preferably, the gravity sensing device includes a gravity sensor, a PCB board connected to the gravity sensor, an automatic controller connected to the PCB board; a connecting device connected to the automatic controller; and the gravity sensing device is connected to the current limiting device via the connecting device.

[0009] Preferably, it is characterized in that the connecting device includes a driving device, a rotating shaft installed on the driving device, and a first connector, a second connector and a third connector installed on the rotating shaft in sequence from left to right.

[0010] Preferably, it is characterized in that the current limiting device includes a substrate, a first resistor installed on the substrate, a second resistor connected in series with the first resistor, and a third resistor connected in series with the second resistor; a first switch is installed on the first resistor, a second switch is installed on the second resistor, and a third switch is installed on the third resistor; the first switch, the second switch and the third switch are connected by a wire.

[0011] Compared with the prior art, this application has the following beneficial effects:

[0012] The utility model adopts a gravity sensing device. When water is poured into the coated paper cup, the gravity sensing device senses gravity and is connected to the current limiting device to be energized, so that the thermal insulation layer generates heat and keeps the water in the paper cup warm. Specifically, when gravity is generated by water in the coated paper cup, the gravity sensor in the gravity sensing device generates induction and transmits the information to the automatic controller through the PCB board. After receiving the information, the automatic controller controls the connection device to be connected to the current limiting device, so that the current limiting device is connected to the power supply and is energized, so that the thermal insulation layer generates heat and keeps the water in the paper cup warm. This solves the cumbersome problem of the existing device that the power switch must be turned on after the device is filled with water, and also solves the problem that the existing device cannot play the role of heat preservation due to insufficient water and the inability to turn on the switch.

[0013] In order to prevent power waste, the present invention is also equipped with a current limiting device in conjunction with a gravity sensing device. When the weight exceeds a certain value of the full water weight, the gravity sensor receives the gravity value and transmits the information to the automatic controller through the PCB board. After receiving the information, the automatic controller controls the driving device to rotate again so that the corresponding connector on the rotating shaft is connected to the corresponding switch. At this time, due to the different weights of the water and the different switches connected, the number of resistors through which the current passes is also different, and the voltage generated is different, thereby effectively preventing power waste.

[0023] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0024] Example 1:

[0025] A laminated paper cup structure with a heat-insulating function includes: a heat-insulating device 10, a heat-insulating cover 20 installed on the heat-insulating device 10, and a laminated paper cup 30 arranged between the heat-insulating cover 20 and the heat-insulating device 10; the heat-insulating device 10 includes a heat-insulating shell 11, a plug 12 installed at the bottom of the heat-insulating shell 11, a gravity sensing device 13 connected to the plug 12 by a wire, a current limiting device 14 connected to the gravity sensing device 13, and a heat-insulating layer 15 connected to the current limiting device 14; the heat-insulating layer 15 is arranged inside the heat-insulating shell 11.

[0026] like Figure 1 and Figure 2 As shown, the laminated paper cup 30 achieves a heat preservation effect through the heat preservation device 10 , and the heat preservation cover 20 is screwed onto the heat preservation device 10 through a threaded structure, further enhancing the heat preservation effect of the laminated paper cup 30 .

[0027] Furthermore, the heat preservation device 10 is connected to a socket in daily life through a plug 12. The connection method can be a USB interface, a data line interface, etc., which is not limited in this embodiment; the laminated paper cup 30 is placed above the gravity sensing device 13. When water starts to be filled in the laminated paper cup 30, the gravity sensing device 13 senses the change in gravity and immediately connects to the current limiting device 14, so that the current limiting device 14 is energized and the heat preservation layer 15 connected to the current limiting device 14 is heated, so that the heat preservation layer 15 can keep the water in the laminated paper cup 30 warm.

[0028] like Figure 2 and Figure 3 As shown, the gravity sensing device 13 includes a gravity sensor 131, a PCB board 132 connected to the gravity sensor 131, an automatic controller 133 connected to the PCB board 132; a connecting device 134 connected to the automatic controller 133; the gravity sensing device 13 is connected to the current limiting device 14 through the connecting device 134.

[0029] The gravity sensing device 13 receives the gravity changes in the coated paper cup 30 through the gravity sensor 131. Once the gravity changes are sensed, the gravity sensing device 13 transmits the information to the automatic controller 133 through the PCB board 132. The automatic controller 133 drives the connecting device 134 to connect with the current limiting device 14, so that the current limiting device 14 is energized and the insulation layer 15 connected to the current limiting device 14 is heated, so that the insulation layer 15 can keep the water in the coated paper cup 30 warm.

[0030] Furthermore, the connecting device 134 includes a driving device 1341, a rotating shaft 1342 installed on the driving device 1341, and a first connector 1343, a second connector 1344 and a third connector 1345 installed on the rotating shaft 1342 from left to right.

[0031] like Figure 4 and Figure 5 As shown, the current limiting device 14 includes a substrate 141, a first resistor 142 mounted on the substrate 141, a second resistor 143 connected in series with the first resistor 142, and a third resistor 144 connected in series with the second resistor 143; a first switch 145 is mounted on the first resistor 142, a second switch 146 is mounted on the second resistor 143, and a third switch 147 is mounted on the third resistor 144; the first switch 145, the second switch 146, and the third switch 147 are connected by wires.

[0032] In order to achieve different insulation effects at different water volumes and reduce power consumption at low water volumes, this embodiment uses a gravity sensor 131 to set the water volume (the gravity can be set according to actual needs and is not limited in this embodiment), and cooperates with the current limiting device 14 to limit the flow at different water levels, effectively preventing waste of electricity.

[0033] This embodiment adopts the following scheme to set the water volume:

[0034] The resistances of the first resistor 142 , the second resistor 143 , and the third resistor 144 are all set to R, and the power supply current is set to I.

[0035] When the water volume is greater than 0 and less than 30% of the full water volume, the gravity sensor 131 receives the gravity change in the coated paper cup 30 and transmits the information to the automatic controller 133. The automatic controller 133 then controls the driving device 1341 in the connecting device 134 to operate. At this time, the driving device 1341 drives the rotating shaft 1342 to rotate, just so that the first connector 1343 on the rotating shaft 1342 is connected to the first switch 145, and the second switch 146 and the third switch 147 are disconnected. At this time, the current flows through the first resistor 142, the second resistor 143 and the third resistor 144 and then flows into the insulation layer 15. After the current passes through the three resistors, U = I / 3R is obtained, and the power is P = I 2 / 3R.

[0036] When the water volume is greater than 30% of the full volume and less than 60% of the full volume, the gravity sensor 131 receives the gravity in the coated paper cup 30 and transmits the information to the automatic controller 133. The automatic controller 133 controls the driving device 1341 in the connecting device 134 to operate again. At this time, the driving device 1341 drives the rotating shaft 1342 to rotate, just so that the second connector 1344 on the rotating shaft 1342 is connected to the second switch 146, and the first switch 145 and the third switch 147 are disconnected. At this time, the current only passes through the second resistor 143 and the third resistor 144 and flows into the insulation layer 15. The voltage under this current is U = I / 2R, and the power is P = I 2 / 2R, this power is significantly greater than the power when the water volume is less than 30% of the full water volume.

[0037] When the water volume is between 60% and full, the gravity sensor 131 receives the gravity in the coated paper cup 30 and transmits the information to the automatic controller 133. The automatic controller 133 controls the driving device 1341 in the connecting device 134 to operate again. At this time, the driving device 1341 drives the rotating shaft 1342 to rotate, just so that the third connector 1345 on the rotating shaft 1342 is connected to the third switch 147, and the first switch 145 and the second switch 146 are disconnected. At this time, the current only passes through the third resistor 144 and flows into the insulation layer 15. The voltage under this current is U=I / R, and the power is P=I 2 / R.

[0038] The above current limiting solution is only one embodiment, and the number of series resistors can be increased or decreased according to actual conditions.

[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims be included in the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.
