Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, in particular to a detachable portable constant temperature insulation cup. Background Art

[0002] Thermos cups are essential drinking tools for modern people's high-quality life. Restricted by manufacturing costs and technical levels, the insulation time of the thermos cups on the market is not long, and cannot meet the normal needs of people's lives. The insulation function of the thermos cups on the market is basically achieved through the vacuum insulation layer between the inner liner and the cup body. The vacuum insulation layer can delay the heat dissipation of liquids such as water in the inner liner, thereby achieving the purpose of insulation. Some other thermos cups achieve the insulation function through materials such as ceramics. Because the thermal conductivity of ceramics is poor, when warm liquid is poured into the inner liner made of ceramic materials, the liquid temperature cannot be quickly conducted out of the inner liner, thereby achieving the insulation function. However, the above two thermos cups only have a simple insulation function, but no heating function, that is, they cannot keep the liquid in the thermos cup at a constant temperature. When water or other liquids are boiled and poured into the thermos cup, the liquid temperature in the cup will slowly drop to room temperature over time. At this time, if you want to increase the temperature of the liquid in the thermos cup, you can only pour the warm liquid into the inner liner again for neutralization, which is inconvenient to use.

[0003] After searching, it was found that there are also heatable thermos cup structures in the prior art. For example, the announcement number CN211354866U is a portable rechargeable constant temperature cup that adopts a cup bottom heating method. It includes a cup body with upper and lower ends opened, and the upper end of the outer side of the cup body is sealed with a thermos cup cover and the bottom end of the cup body is connected to a bottom cover, so that a sealed space is formed inside the cup body, and a thermal insulation liner is fixedly installed in the sealed space of the cup body, and a heating device is installed at the bottom of the cup body and below the thermal insulation liner. The heating device includes a heating plate and an inner base. The inner base is fixedly installed at the bottom of the cup body and is arranged against the upper surface of the bottom cover. The heating plate is glued to the outer surface of the thermal insulation liner and is electrically connected to the battery installed on the inner base.

[0004] However, since the cup body and the bottom cover in this structure are non-detachably fixedly connected, the entire thermos cup needs to be moved when charging, which makes it inconvenient to use. In addition, the thermos cup has a charging structure with a high overall height and a large volume, and the non-detachable structure also makes it less portable. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the present invention more clear, a detachable portable constant temperature insulation cup of the present invention is further described below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0023] like Figures 1 to 3 As shown, a detachable portable constant temperature insulation cup includes an insulation cup body 100, and the insulation cup body 100 is covered with a cup cover 200, and the covering method can be threaded connection, card connection or plug-in connection, etc., to achieve the purpose of opening the insulation cup. Of course, the cup cover 200 itself can also be provided with an opening and closing component for opening the insulation cup. The insulation cup body 100 includes an outer shell 110 and an inner liner 120 located in the outer shell 110. The outer shell 110 is composed of a side shell 111 of a metal material and a bottom shell 112 of a plastic material, which is combined into a cylindrical shape, and a heating element 130 for heating and a temperature sensor 140 for detection are provided inside, and the heating element 130 and the temperature sensor 140 are both located at the bottom of the inner liner 120. An exposed connector 150 is also provided at the bottom of the outer shell 110, and the heating element 130 and the temperature sensor 140 are electrically connected to the connector 150 respectively. The inner liner 120 is a container for holding liquid and has a barrel-shaped structure as a whole. It is made of non-toxic and harmless safe materials, such as food-grade stainless steel.

[0024] The base 300 is detachably connected to the bottom of the thermos cup body 100 through a screw-on structure 400. The base 300 includes a seat shell 310 formed by a seat wall 312 and a seat bottom 313 in a cylindrical shape. The top of the seat shell 310 has a mounting groove 311 that matches the shape of the bottom of the thermos cup body 100. A rechargeable power module 320 and a control module 330 are provided inside the seat shell 310. An exposed electrode contact pin 340 is provided at the bottom of the mounting groove 311. The electrode contact pin 340 has elastic and retractable properties and can form an electrical coupling with the connector 150. The control module 330 is connected to the power module 320 and the electrode contact pin 340, respectively. When the thermos cup body 100 is connected to the base 300, the electrode contact pin 340 is inserted into the connector 150 to form an electrical coupling, so that the electrical components in the thermos cup body 100 and the base 300 can form signal transmission and power transmission. In this embodiment, the power module 320 includes a rechargeable lithium battery 321 and a Type-C charging port 322; the control module 330 includes a circuit board 331 with an integrated control chip, a button switch 332 and a display screen 333, etc. The control module 330 has the functions of realizing the switch of the entire thermos cup as well as liquid heating, constant temperature setting, and heat preservation. Since the control module 330 itself is conventional technology, it will not be elaborated here.

[0025] Combination Figure 4As shown, the screw-on structure 400 includes a buckle head 410 disposed on the peripheral side surface of the bottom shell 112 of the housing 110 and a clamping groove 420 disposed on the inner side wall of the mounting groove 311 at the top of the base 300. The bottom of the bottom shell 112 can be inserted into the mounting groove 311 with a gap. The clamping groove 420 includes a first groove portion 421 which is vertically disposed and open at the upper end, and a second groove portion 422 which is connected to the bottom of the first groove portion 421. The width dimension of the first groove portion 421 is slightly larger than the width dimension of the buckle head 410. The second groove portion 422 is transversely disposed along the inner wall of the mounting groove 311 in the length direction, and the groove width dimension is slightly larger than the thickness dimension of the buckle head 410. In this way, when the thermos cup body 100 and the base 300 are connected, when the buckle 410 is inserted from the first groove 421 to the bottom, the thermos cup body 100 and the base 300 rotate relative to each other, and the buckle 410 moves along the length direction of the second groove 422 until the end of the groove, and at the same time, the electrode contact pin 340 elastically contracts, and when the thermos cup body 100 and the base 300 rotate into place, they are elastically inserted into the connector 150 to form an electrical coupling; according to the above installation steps, the reverse operation is performed, and the thermos cup body 100 and the base 300 are separated from each other and electrically disconnected. Of course, in order to ensure that the card slot 420 and the buckle 410 can be locked with each other when mating, the buckle 410 can be elastically squeezed in the second groove 422, for example, by changing the groove depth of the second groove 422, or the second groove 422 has a downwardly inclined groove path. In addition, in order to ensure the connection stability of the detachable structure in this embodiment, the buckle head 410 and the card slot 420 are correspondingly arranged in plurality and are evenly distributed around the circumference of the central axis of the thermos cup.

[0026] Considering the heat preservation effect of the thermos cup, it is preferred to set the thermos cup body to the following structure: the inner liner 120 is vacuum-isolated from the outer shell 110, that is, the two ends of the inner liner 120 are respectively sealed and welded to the outer shell 110, and the middle area forms a closed isolation space with a certain degree of vacuum; there is a recessed groove 121 with a notch downward at the bottom of the inner liner 120, and the heating element 130 and the temperature sensor 140 are attached to the bottom of the recessed groove 121, and the two are spaced a certain distance apart, which can reduce the detection disturbance of the temperature sensor 140, and the heat generated by the heating element 130 is directly conducted to the inner liner 120. In this embodiment, the heating element 130 is preferably a PI film heating sheet, which has the advantages of small overall volume, light weight and easy installation under the premise that the heating power meets the requirements.

[0027] Furthermore, if Figure 5 As shown, the inner surface of the inner liner 120 is provided with a polishing layer 122 and the outer surface is provided with a copper-plated layer 123. The polishing layer 122 has a high surface finish and can reduce stain adhesion; the copper-plated layer 123 can reduce vacuum radiation, effectively block temperature conduction and convection, and delay heat dissipation of the liquid in the cup to keep warm and lock in cold.

[0028] In order to improve the heating uniformity of the thermos cup, Figure 2 , Figure 3 As shown, a micro vibration motor 160 is also provided on the side wall of the recessed groove 121, and the micro vibration motor 160 is electrically connected to the connector 150. When the liquid in the thermos cup is heated, the micro vibration motor 160 generates high-frequency vibration to drive the liquid in the inner liner to vibrate, accelerate the flow of the liquid, thereby increasing the contact amount between the liquid and the bottom of the recessed groove 121, and improving the heating uniformity and efficiency.

[0029] This thermos cup has heating, constant temperature and heat preservation functions when in use. More importantly, the base 300 and the thermos cup body 100 are detachable. When the base 300 needs to be charged, it can be charged by simply moving the base 300 alone; when carrying it out, the base 300 and the thermos cup body 100 can be placed separately to reduce the height of the thermos cup, making it easier to store and carry; in addition, the thermos cup body adopts a hollow and copper-plated structure to improve the heat preservation effect; by providing a micro vibration motor 160, the uniformity and efficiency of liquid heating are improved.

[0030] The above embodiments of the utility model are merely examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the utility model still belong to the protection scope of the utility model.
