Description

Technical Field

[0001] The present invention relates to the technical field of paper cups, and in particular to a paper cup heat preservation device with heat preservation function. Background Art

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

[0003] After searching, Chinese invention 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 with a connecting piece. The interior of the connecting piece is provided with a heat preservation cup body, and the interior of the heat preservation cup body is provided with a heating layer. The interior of the heating layer is provided with a paper cup body, and the bottom of the paper cup body is connected to a bearing plate, and the bottom of the bearing plate is installed with a connecting column. The bottom of the paper cup body of the present invention contacts the bearing plate, and the interior of the paper cup body is filled with water. Gravity causes the bearing 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, and the switch is turned on to drive the heating layer to heat and keep the paper cup body warm, so that the heat preservation performance is better. When there is no water in the paper cup body, the reset spring drives the 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 paper cup body is filled with water, gravity causes the load-bearing plate to drive the connecting column to descend, and the connecting column squeezes the reset spring, causing the connecting plate at the bottom of the connecting column to press the switch, and the switch is turned on to drive the heating layer to heat and keep the 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 performed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a paper cup heat preservation device with heat preservation function. The structure has the function of heat preservation when a certain amount of water is present.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A paper cup heat preservation device with heat preservation function comprises: a heat preservation device, a heat preservation cover installed on the heat preservation device, and a paper cup arranged between the heat preservation cover and the heat preservation device; the heat preservation device comprises a heat preservation shell, a plug installed at the bottom of the heat preservation shell, a telescopic current limiter connected to the plug wire, a current controller installed on the telescopic current limiter, a heating device connected to the current controller wire, a mercury box installed on the heating device, and a spiral pipe installed on the mercury box; the spiral pipe is arranged in the inner wall of the heat preservation shell; the heating device is connected to the plug through a wire.

[0008] Preferably, the telescopic current limiter comprises a lifting device, a substrate for mounting the lifting device, a resistor mounted on the substrate, and a connecting piece arranged on the resistor; the resistor is composed of a plurality of resistor bars.

[0009] Preferably, the resistor body includes a first resistor bar, a second resistor bar, a third resistor bar, a fourth resistor bar and a fifth resistor bar; the first resistor bar, the second resistor bar, the third resistor bar, the fourth resistor bar and the fifth resistor bar are connected in series; the first resistor bar, the second resistor bar, the third resistor bar, the fourth resistor bar and the fifth resistor bar are all provided with connecting parts, and are all arranged at the end where current flows out.

[0010] Preferably, the lifting device includes a fixed cylinder, a limit plate installed in the fixed cylinder, a lifting rod installed on the limit plate, and a spring sleeved on the lifting rod; the spring is installed between the fixed cylinder and the limit plate.

[0011] Preferably, the current controller comprises a receiving plate, an expander group mounted on the receiving plate, and parallel wires connected to the expander group; the expander group is composed of a plurality of expanders, and the number of the expanders is the same as the resistance strip.

[0012] Preferably, the expander group includes a first expander, a second expander, a third expander, a fourth expander and a fifth expander; the first expander and the connecting piece position on the first resistor bar correspond to each other up and down; the second expander and the connecting piece position on the second resistor bar correspond to each other up and down; the third expander and the connecting piece position on the third resistor bar correspond to each other up and down; the fourth expander and the connecting piece position on the fourth resistor bar correspond to each other up and down; the fifth expander and the connecting piece position on the fifth resistor bar correspond to each other up and down; the lengths of the expansion needles in the first expander, the second expander, the third expander, the fourth expander and the fifth expander decrease in sequence.

[0013] Preferably, the heating device comprises a heating box and an electric heating wire arranged in the heating box.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] The present invention adopts a telescopic current limiter and a current controller. The resistor in the telescopic current limiter sets the number of resistor bars according to the water volume, and sets the number of telescopes according to the number of resistor bars. In this solution, five resistor bars are set based on the fact that a cup of water is 200 ml and 40 ml is set as a level. When the water in the cup reaches 40 ml, the telescopic needle of the first telescope contacts the connector on the first resistor bar. At this time, the power supply is connected, and the heating device starts to heat, so that the mercury in the mercury box rises to the insulation shell along the spiral pipe, and the heat is transferred to the paper cup through the mercury for insulation.

[0016] The present invention adopts the above-mentioned step-by-step connection method to provide heat supply and heat preservation, and adopts the principle of mercury expansion due to heat, which can effectively solve the existing empty cup heat preservation problem caused when the water volume is lower than the heating layer, and reduce the waste of electricity; specifically, when the water in the water cup is between 40ml and 80ml, after passing through, the current must pass through five resistor bars before reaching the heating wire for heating. At this time, the heat generated by the heating wire can only keep the mercury at the water level in the water cup. When the water volume in the water cup exceeds 80ml, the telescopic needle of the second telescope contacts the connector on the second resistor bar. At this time, the first resistor bar is in parallel state. According to the principle of current priority, the current will directly pass through the second resistor bar to reach the heating wire for heating. At this time, the current passes through one less resistor bar, so the current is larger than when it passes through five resistors, that is, the heating wire can generate more heat, push the mercury to a higher place, and keep the water warm; by analogy, mercury will always appear at the water level to be kept warm to keep the water warm.

[0030] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0031] Embodiment 1:

[0032] A paper cup heat preservation device with heat preservation function comprises: a heat preservation device 10, a heat preservation cover 20 installed on the heat preservation device 10, and a paper cup 30 arranged between the heat preservation cover 20 and the heat preservation device 10; the heat preservation device 10 comprises a heat preservation shell 11, a plug 12 installed at the bottom of the heat preservation shell 11, a telescopic current limiter 13 connected to the plug 12 by a wire, a current controller 14 installed on the telescopic current limiter 13, a heating device 15 connected to the current controller 14 by a wire, a mercury tank 16 installed on the heating device 15, and a spiral pipe 17 installed on the mercury tank 16; the spiral pipe 17 is arranged in the inner wall of the heat preservation shell 11; the heating device 15 is connected to the plug 12 by a wire.

[0033] like Figures 1 to 3 As shown, the 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, thereby further enhancing the heat preservation effect of the paper cup 30 .

[0034] Furthermore, the heat preservation device 10 is connected to a socket in daily life through a plug 12, and the connection method can be a USB interface, a data line interface, etc., which is not limited in this embodiment; the paper cup 30 is above the current controller 14, and the current controller 14 is installed on the telescopic current limiter 13. When water starts to be filled in the paper cup 30, the current controller 14 will slowly drop under the action of gravity. When it contacts and energizes the telescopic current limiter 13, the current will be transmitted to the heating device 15 through the wire connected to the current controller 14, so that the heating device 15 starts to heat and heats the mercury tank 16 arranged on the heating device 15, so that the mercury in the mercury tank 16 expands and flows to the entire heat preservation shell 11 through the spiral pipe 17, thereby achieving the insulation of the water in the paper cup 30.

[0035] like Figure 3 and Figure 4 As shown, the telescopic current limiter 13 includes a base plate 132 , and the base plate 132 is installed with four lifting devices 131 . The current controller 14 is installed on the four lifting devices 131 . The lifting and lowering of the current controller 14 is achieved through the lifting and lowering functions of the four lifting devices 131 .

[0036] Furthermore, a resistor 133 is installed on the substrate 132 , and current is limited by the resistor 133 . A connector 134 is installed on the resistor 133 .

[0037] Furthermore, the lifting device 131 is installed on the base plate 132 through a fixed tube 1311, and is connected to the current controller 14 through a lifting rod 1313 inserted in the fixed tube 1311. A limiting plate 1312 is installed under the lifting rod 1313, and the lifting function is realized by a spring 1314 sleeved on the lifting rod 1313. The spring 1314 is installed in the fixed tube 1311.

[0038] like Figure 6 As shown, the current controller 14 includes a receiving plate 141, on which a retractor group 142 is installed. When the current controller 14 descends, the retractor group 142 supports the connecting piece 134 to be energized, generating current, which then flows into the heating device 15 through the parallel wire 143 connected to the retractor group 142 to heat the heating device 15.

[0039] like Fig. 9 As shown, the heating device 15 includes a heating box 151, and the heating box 151 is provided with a heating wire 152. One end of the heating wire 152 is connected to the parallel wire 143, and the other end is connected to the plug 12; when current passes through the heating wire 152, heat is generated to heat the mercury box 16.

[0040] In the prior art, no matter how much water is in the paper cup 30, the same heating power is always guaranteed, resulting in a waste of electricity. In order to solve this problem and meet the requirements at the same time, a certain amount of water is injected into the paper cup 30 to activate the heat preservation effect.

[0041] In this embodiment, a cup of water is 200 ml, and each 40 ml is a level, and the heat preservation effect is divided into 5 levels. Of course, the five levels are not unique and can be divided according to actual needs.

[0042] In order to meet the five-level effect, such as Figure 5 As shown, the substrate 132 is installed with a resistor body 133, and the resistor body 133 is provided with five resistor bars according to the five-level effect; the five resistor bars are named as the first resistor bar 1331, the second resistor bar 1332, the third resistor bar 1333, the fourth resistor bar 1334 and the fifth resistor bar 1335 for distinction; the first resistor bar 1331, the second resistor bar 1332, the third resistor bar 1333, the fourth resistor bar 1334 and the fifth resistor bar 1335 are connected in series; the first resistor bar 1331, the second resistor bar 1332, the third resistor bar 1333, the fourth resistor bar 1334 and the fifth resistor bar 1335 are all provided with a connecting piece 134, and are all arranged at the end where the current flows out.

[0043] like Figures 6 to 8As shown, the retractors correspond to the resistor bars one by one, so there are five retractors. In order to distinguish them, the five retractors are named as the first retractor 1421, the second retractor 1422, the third retractor 1423, the fourth retractor 1424 and the fifth retractor 1425 respectively; the first retractor 1421, the second retractor 1422, the third retractor 1423, the fourth retractor 1424, the fifth retractor 1425 and the connector 134 on the first resistor bar 1331, the second resistor bar 1332, the third resistor bar 1333, the fourth resistor bar 1334 and the fifth resistor bar 1335 are arranged in one-to-one correspondence; the lengths of the retractable needles in the first retractor 1421, the second retractor 1422, the third retractor 1423, the fourth retractor 1424 and the fifth retractor 1425 decrease successively.

[0044] like Figures 1 to 9 As shown, according to the above setting of this example, its working principle is as follows: when water starts to be poured into the paper cup 30 on the receiving plate 141, the receiving plate 141 rises due to gravity, and slowly descends under the lifting device 131. When the amount of water in the paper cup 30 reaches 40 ml, the telescopic needle of the first telescope 1421 on the receiving plate 141 contacts the connecting piece 134 of the first resistor bar 1331. At this time, the power is turned on, and the current flows out from the plug 12, passes through the fifth resistor bar 1335, the fourth resistor bar 1334, the third resistor bar 1333, the second resistor bar 1332 and the first resistor bar 1331 in sequence for current limiting, and then flows into the heating wire 152 through the parallel wire 143, so that the heating wire 152 generates heat, heats the mercury box 16, and causes the mercury in the mercury box 16 to heat and expand, and rise to the spiral pipe 17 to heat and keep the heat-insulating shell 11.

[0045] When the telescopic needle of the first telescoping device 1421 contacts the connecting piece 134 of the first resistor bar 1331, the current is limited through the five resistor bars. The current is minimum in the current state, so that the heating wire 152 generates the minimum heat. According to the principle of mercury expansion, the higher the heat, the greater the expansion. Under low heat, the mercury cannot fill the entire spiral pipe 17. Therefore, by controlling the heating value of the heating wire 152, the height that the mercury can reach in this case is exactly at the water level position in the paper cup 30. This not only prevents waste of electricity, but also concentrates the heating and heat preservation effect on the water-containing part, preventing heating from occurring in the empty cup and scalding the paper cup.

[0046] According to the above description, when water is continuously poured into the paper cup 30, the receiving plate 141 will continue to drop. When the amount of water reaches 80 ml, the retractable needle of the second retractor 1422 contacts the second resistor bar 1332. At this time, although the first retractor 1421 is also connected to the first resistor bar 1331, the first resistor bar 1331 is in parallel. According to the principle of current priority, the current will bypass the first resistor bar 1331 and directly enter the parallel wire 143, and then flow into the heating wire 152, so that the heating wire 152 generates heat to heat the mercury box 16; at this time, the current directly passes through the fifth resistor bar 1335, the fourth resistor bar 1334, the third resistor bar 1333 and the second resistor bar 1332. The current at this time exceeds the current when the water volume is 40 ml, that is, at this time, the heat generated by the heating wire 152 is higher than that at 40 ml, and the height of the mercury rise is also higher than that at 40 ml. Of course, the height of the mercury still remains at the water level.

[0047] 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 the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.
