in a steam heating state, referring to fig. 5, 6, 10 and 12, adding a proper amount of water into the kettle body assembly, adjusting the vent valve 16 at the lower end of the inner cylinder assembly to be in an open state, then combining the inner cylinder assembly with the kettle body assembly, adjusting the inner cylinder assembly to enable the first vent hole 20 to be positioned at the spout 19, putting an article to be heated into the inner cylinder assembly, and covering the kettle cover assembly on the upper end of the inner cylinder assembly; after the kettle body assembly is electrified to work, steam generated in the inner container 13 enters the cylinder body 12 in the inner cylinder assembly through the vent valve 16, directly heats objects in the cylinder body 12, and if too much steam is exhausted to the outside through the first vent hole 20 at the kettle nozzle 19, so that the purpose of steam heating is achieved.

Referring to fig. 5, 11 and 12, when the multipurpose portable electric kettle is used for dry heating and steam heating of articles, a proper amount of water needs to be added into the kettle body assembly, wherein the proper amount of water means that the lower end of the inner cylinder assembly is not contacted with the water in the kettle body assembly after the inner cylinder assembly and the kettle body assembly are combined; therefore, when the dry heating is carried out, the steam generated in the kettle body component can smoothly enter the clearance between the inner cylinder component and the kettle body component, and when the steam heating is carried out, the steam generated in the kettle body component can smoothly enter the inner cylinder component through the vent valve 16; in order to more conveniently control the water quantity, a water level line can be marked on the inner wall of the inner container 13, a liquid level sensor 25 capable of feeding back real-time water quantity C1 in the inner container 13 to the controller can be arranged at the bottom of the inner container 13, the controller can display the acquired real-time water quantity C1 data, and assuming that the maximum water quantity allowed in the kettle body assembly during dry heating and steam heating is C2, under the two conditions that C1 is larger than C2 and C1 is not larger than C2, the display form of the controller for the real-time water quantity C1 is different, for example, when C1 is larger than C2, the display screen of the controller displays the real-time water quantity C1 in red, and when C1 is not larger than C2, the display screen of the controller displays the real-time water quantity C1 in green, so that a user can conveniently judge whether the real-time water quantity C1 is appropriate or not during dry heating and steam heating; and if the multipurpose portable electric kettle is used for boiling water, the real-time water quantity C1 data is not needed to be noticed.

When the multipurpose portable electric kettle is used for carrying out dry heating or steam heating on articles, the modes of 'timing heating', 'constant temperature heating', 'continuous boiling', 'intermittent boiling' and the like can be adopted for working by means of the coordination and the coordination of the controller, the temperature sensor 21 and the electromagnetic coil 14, so that a proper heating effect is realized; since steam does not enter the cylinder 12 during dry heating, it can be used to heat food or the like which is not suitable for wetting and has a low heating temperature requirement; because when steam heating, high temperature steam can get into 12 intracavity of barrel and directly heat article, so can be used to heating articles such as the food of being afraid of to soak, simultaneously because steam temperature is higher than the temperature of boiling water, can carry out high temperature heating or high temperature disinfection to some articles by the mode of steam heating, and the effect is comparatively ideal.

When the multipurpose portable electric kettle is used for carrying out dry heating and steam heating on objects, the inner cylinder assembly is often required to be placed in or taken out of the inner container 13, and the objects are often required to be placed in or taken out of the inner cylinder assembly, so that the rotating mechanism 5 is not required to be arranged between the inner cylinder assembly and the kettle cover assembly, and the rotating mechanism 5 which can be disassembled and assembled can be arranged between the inner cylinder assembly and the kettle cover assembly according to special requirements of different users.

In the multipurpose portable electric kettle, the inner barrel component is the most obvious distinguishing characteristic of the traditional electric kettle and cannot be arranged, the added multipurpose portable electric kettle inevitably increases the overall weight of the multipurpose portable electric kettle, has certain negative effect on improving portability, but has obvious advantages; on one hand, in the carrying process, the inner cavity of the cylinder body 12 has a certain storage function, the cup seat 18 at the lower end of the cylinder body 12 can be used for placing the nested cup group 15, and the nested cup group 15 is prevented from contacting with the inner wall of the inner container 13; on the other hand, when the multipurpose portable electric kettle is used, the combination of the inner cylinder component and the kettle body component enables the multipurpose portable electric kettle to have two heating functions of dry heating and steam heating which are respectively suitable for different objects, the two functions are very practical in journey life, and in addition, when the multipurpose portable electric kettle is used for boiling water, the idle inner cylinder component can be used as a cup holder and a storage container; therefore, the technical effect brought by the addition of the inner barrel assembly is more beneficial than disadvantages; and along with the continuous research and development of novel material, if the inner tube subassembly adopts the heat-resisting material of low density to make, can effectively reduce the dead weight, can make the drawback that its demonstrates almost negligible.

In conclusion, the multipurpose portable electric kettle adopts a scientific and reasonable structure, the kettle body components are designed based on a slender column shape, and each component has various combination modes, so that the multipurpose portable electric kettle is convenient to carry during travel and has a certain storage function; the multifunctional portable electric kettle not only has the function of boiling water, but also has two heating modes of dry heating and steam heating, and can meet the requirements of heating or high-temperature disinfection on food and other articles in the journey, namely, the multifunctional portable electric kettle is extremely suitable for being carried in the journey to improve the quality of life in the journey.

Further, referring to fig. 2 and 9, in the multi-purpose portable electric kettle, a rotating mechanism 5 is arranged between the lid assembly and the kettle body assembly, when the multi-purpose portable electric kettle is used for boiling water, the lid assembly and the kettle body assembly can be combined together by the rotating mechanism 5, and the lid assembly can be turned over, that is, the lid assembly can be opened and closed, and based on the technical purpose, the rotating mechanism 5 can adopt the following structure:

as shown in fig. 5, 7 and 13, the rotating mechanism 5 includes a horizontal column 51 having magnetism and fixedly connected to the outer corner of the upper end of the rib 8, and a rotating base 52 fixed to the lower side of the pressing handle 4 and capable of attracting the horizontal column 51, a semicircular groove 53 capable of being buckled on the horizontal column 51 is formed on the lower end surface of the rotating base 52, and the semicircular groove 53 is matched with the horizontal column 51 to combine the pot lid assembly and the pot body assembly and allow the pot lid assembly to turn around the horizontal column 51 between a horizontal state and a vertical state;

when the multipurpose portable electric kettle is used for boiling water, the kettle cover component and the kettle body component are combined with the horizontal column 51 by virtue of the rotating seat 52, when the pressing handle 4 is pressed down, the kettle cover component turns over around the horizontal column 51, namely the kettle cover component is lifted, and after the pressing handle 4 is released, the kettle cover component falls down under the action of self weight and is closed; if the magnetic attraction between the rotary seat 52 and the horizontal column 51 is overcome by a little force, the pot lid assembly can be separated from the pot body assembly.

Further, referring to fig. 1 and 3, the multipurpose portable electric kettle is provided with a folding handle 7, the folding handle 7 is folded and stored in the storage groove 6, extending to the outside of the rib 8 when unfolding, the folding handle 7 has various embodiments, for example, the folding handle 7 can be a round handle, the upper end of the round handle is rotatably fixed in the receiving groove 6, the round handle can be lifted to the horizontal state and locked when in use, the round handle can be rotated to the vertical state and positioned in the receiving groove 6 when in carrying, thereby realizing the necessary functions of the folding handle 7, but the design influences the appearance of the multipurpose portable electric kettle, meanwhile, the use habit of people to the electric kettle is not met, and obviously, the traditional design is not reasonable enough when being applied to the multipurpose portable electric kettle. Therefore, the invention also provides an improved design for the folding handle 7, which adopts the following specific structure:

as shown in fig. 5, 10, 14, 15 and 16, the folding handle 7 includes an upper section 71 and a lower section 74 hinged via an intermediate shaft 73, the upper end of the upper section 71 is fixed in the accommodating groove 6 by a fixed shaft 72, the lower end of the lower section 74 is provided with two guide pins 234 whose central axes are overlapped and respectively extend to the outside of the left and right sides of the lower section 74, the intermediate shaft 73, the fixed shaft 72 and the two guide pins 234 are parallel; two side walls of the middle lower part of the containing groove 6 are provided with symmetrical guide grooves 22 extending up and down, and the outer ends of the two guide pins 234 are respectively inserted into the two guide grooves 22 and can move up and down along the guide grooves 22; when the intermediate shaft 73 is positioned outside the accommodating groove 6 and the guide pin 234 is positioned at the upper end of the guide groove 22, the upper section 71, the lower section 74 and the rib 8 are distributed in a triangular shape, and the folding handle 7 is in an unfolded state; when the upper section 71 and the lower section 74 are both attached to the bottom of the accommodating groove 6, the folding handle 7 is in a folding state and is completely accommodated in the accommodating groove 6; a locking mechanism 23 is arranged between the lower section 74 and the containing groove 6, when the folding handle 7 is in the unfolding state, the locking mechanism 23 can lock the lower end of the lower section 74, so that the folding handle 7 has higher stability in the unfolding state; two side walls of the middle upper part of the containing groove 6 are respectively provided with an arc-shaped gap 24, when the folding handle 7 is in a folding state, two sides of a joint between the upper section 71 and the lower section 74 are exposed through the arc-shaped gaps 24 so as to be convenient to hold;

when the multipurpose portable electric kettle is carried, the joint of the upper section 71 and the lower section 74 is pressed downwards, so that the folding handle 7 is in a folding state and is completely accommodated in the accommodating groove 6; when the multipurpose portable electric kettle is used, the two sides of the joint of the folding handle 7 are held at the arched notch 24 and are lifted outwards, so that the folding handle 7 is in an unfolded state, then the lower end of the lower section 74 is locked by the locking mechanism 23, at the moment, the folding handle 7 extends to the outer side of the containing groove 6 and keeps a stable triangular structure, an operator can hold the kettle cover conveniently with one hand, the opening and closing of the kettle cover assembly can be controlled by using a thumb, the use habit of people is met, and the appearance is more attractive.

Referring to fig. 5, in the folding handle 7, a locking mechanism 23 is disposed between the lower section 74 and the receiving slot 6, and the locking mechanism 23 is used for locking the lower end of the lower section 74 to keep the folding handle 7 in the unfolded state, for this purpose, the locking mechanism 23 is relatively easy to be implemented by the prior art, for example, a positioning screw can be installed on the lower section 74, and a positioning hole 230 is disposed at the bottom of the receiving slot 6, when the folding handle 7 is in the unfolded state, the positioning screw can be inserted into the positioning hole 230 by rotation, so as to achieve the purpose of locking the lower end of the lower section 74, and when the locking is released, the positioning screw can be rotated to move out of the positioning hole 230; however, if the locking mechanism 23 is designed conventionally, on one hand, the positioning screw needs to be manually screwed to complete the locking and unlocking of the lower section 74 each time, which is not convenient and fast to operate, and on the other hand, the locking mechanism 23 is not beautiful enough in appearance and not very reliable in stability. Therefore, the invention also provides an innovative design for the locking mechanism 23, which adopts a structure specifically as follows:

referring to fig. 14, 15 and 16, the locking mechanism 23 includes a slot seat 236 opened on the lower section 74 and located on the upper side or the lower side of the two guide pins 234, a button 231 capable of moving forward and backward is provided in the slot seat 236, and a trapezoidal hole 232 with a small front and a large rear is opened on the button 231 for passing through the upper and lower holes; the two guide pins 234 are limited by pin holes 237 formed in the lower section 74 and can only move axially, the pin holes 237 are communicated with the groove seats 236, a pushing spring 235 for driving the two guide pins to move away is arranged between the two guide pins 234, and the opposite ends of the two guide pins 234 are respectively provided with crank arms 233 which are perpendicular to the guide pins 234 and extend into the trapezoidal holes 232; the two guide grooves 22 are respectively provided with a blind hole-shaped positioning hole 230 on the side wall of the upper end part; when the two guide pins 234 move to the upper ends of the guide slots 22, the pushing springs 235 drive the outer ends of the two guide pins 234 to be inserted into the two positioning holes 230, and the button 231 is driven by the crank arm 233 to move outwards, i.e. the lower end position of the lower section 74 is locked; when the button 231 is pressed downwards, the trapezoidal hole 232 drives the two crank arms 233 to move towards the middle, the two guide pins 234 retract respectively and move out of the positioning holes 230, and the locking of the lower end of the lower section 74 is released;

therefore, when the folding handle 7 is adjusted to the unfolding state, the locking mechanism 23 can automatically lock the lower end position of the lower section 74, so that the folding handle 7 can stably maintain the unfolding state; when folding the folding handle 7, the button 231 is pressed, the two guide pins 234 are retracted respectively and moved out of the two positioning holes 230, and then the button 231 is pressed to pull the lower section 74 downwards, so that the folding handle 7 can be adjusted to the folding state.

Further, referring to fig. 6, 11 and 12, in the multipurpose portable electric kettle, a vent valve 16 capable of switching the communication state of the lower end of the inner cavity of the cylinder 12 with the outside is installed in the cup base 18, the vent valve 16 has the function that, in the dry heating process, the vent valve 16 keeps the closed state, the water vapor generated in the inner container 13 can not enter the cylinder 12 through the vent valve 16, in the steam heating process, the vent valve 16 keeps the open state, the water vapor generated in the inner container 13 can enter the cylinder 12 through the vent valve 16, and based on the above purpose of the vent valve 16, the existing valve device with two working states of closing and opening is adopted; however, considering that the conventional valve device generally has a complex structure and a large volume, in the multi-purpose portable electric kettle, in order to ensure that the steam generated in the inner container 13 can rapidly enter the barrel 12 to ensure the heating efficiency, the vent valve 16 must have a large ventilation amount when being opened, so that the volume of the vent valve 16 is further increased, which is not beneficial to ensuring the compactness of the inner barrel assembly, and simultaneously increases the implementation difficulty. Therefore, the invention also provides an improved design of the vent valve 16, which comprises the following specific structures:

as shown in fig. 17, the vent valve 16 includes a screw cap 162 located in the cup 18, the screw cap 162 is in threaded fit with the cup 18 to adjust the axial relative position, the upper end of the cup 18 is communicated with the inner cavity of the barrel 12, the inner wall of the upper end of the cup 18 is provided with a circle of inner convex steps 164, the upper side of the inner convex steps 164 is used for installing a filter screen 29, the lower side is used for being in sealing contact with the upper end of the screw cap 162, the filter screen 29 is flush with the upper end faces of the two at the bottom of the barrel 12, the cup 18 is provided with a plurality of air inlet holes 161 penetrating through the side wall at the lower side of the inner convex steps 164, when the upper end of the screw cap 162 is in sealing contact with the lower side of the inner convex steps 164, the lower end of the inner cavity of the barrel 12 is blocked by the screw cap 162, and when the upper end of; in order to facilitate the screwing of the screw cap 162, a linear protrusion 163 may be provided at a lower end of the screw cap 162.

Further, referring to fig. 2, 3 and 4, in the multipurpose portable electric kettle, the cups in the nested cup group 15 can be combined together in a nested and clamped manner, so that the lower end of the inner barrel assembly can be integrally placed during carrying, generally speaking, a plurality of cups can be combined in a nested and clamped manner, which is common in the prior art, for example, a plurality of paper cups, plastic cups and the like which are commonly used in life are combined in a manner before use, and then packaged, and meanwhile, in order to facilitate the combination of a plurality of cups, a plurality of cups in the nested cup group 15 can be designed into different sizes, and can be nested and combined according to the size sequence; however, in the present invention, since the nested cup set 15 needs to be carried along with other components, in order to ensure that the cups in the nested cup set 15 are not automatically separated and the nested cup set 15 is not entirely separated from the cup seat 18 during carrying, the cups can be made of low-density materials, so as to reduce the self-weight of the cups, and besides, the structure of the cups can be optimized and improved to improve the stability of the nested cup set 15 after combination, the specific implementation mode is:

as shown in fig. 18, the outer wall of the upper end of each cup in the nested cup set 15 is provided with a damping sleeve 31 made of rubber material, and the damping sleeve 31 and the inner wall of the cup mouth of the cup nested outside the damping sleeve 31 have a larger friction coefficient, so as to improve the stability of the nested, clamped and combined multiple cups; the outer side of the cup base 18 is also provided with a damping sleeve 31 sleeved outside the cup base, and the damping sleeve 31 and the inner wall of the cup opening of the cup sleeved outside the damping sleeve 31 have larger friction coefficient, so that the stability of the whole nested cup set 15 and the cup base 18 after combination is improved.

Further, when the multipurpose portable electric kettle is used for boiling water, the idle inner cylinder assembly is placed on a table top and can be used as a storage container, after the dry heating and steam heating of objects are completed, the inner cylinder assembly sometimes needs to be taken out of the kettle body assembly and placed on a table, but the lower end of the cylinder 12 is provided with the cup seat 18, and the cup seat 18 is used for clamping and fixing the nested cup group 15, so the diameter of the cup seat 18 is not too large, if the inner cylinder assembly is supported by the cup seat 18, the inner cylinder assembly is not stable enough and is easy to incline, therefore, the multipurpose portable electric kettle further has the following improvements to the inner cylinder assembly:

as shown in fig. 17 and 18, the bottom of the cylinder 12 is provided with a base 30 extending downward along the bottom outer circle, and the cup base 18 is located in the cylinder cavity of the base 30, so that when the inner cylinder assembly is placed on the table surface, the inner cylinder assembly is supported by the base 30 instead of the cup base 18, thereby being stable.

Furthermore, 5, 6, 11 and 12 show that the above-mentioned multipurpose portable electric kettle has two heating functions of dry heating and steam heating, but each heating function is realized based on a specific combination mode of the inner cylinder component and the kettle body component, and the relative relationship between the inner cylinder component and the kettle body component can be determined by observing the relative positions of the first exhaust hole 20 and the second exhaust hole 27 and the spout 19, but the operation mode is not convenient enough, and the inner cylinder component and the kettle body component cannot be quickly and correctly combined according to the needs. Therefore, the multipurpose portable electric kettle also has the following improvements:

as shown in fig. 19 and 20, the upper end of the inner barrel assembly is provided with a pointer 28, and the upper end of the kettle body assembly is marked with three status marks 26, when the inner barrel assembly and the kettle body assembly are combined and the pointer 28 points to the three status marks 26 respectively, the combination status of the inner barrel assembly and the kettle body assembly is respectively:

a. the first exhaust hole 20 and the second exhaust hole 27 are not communicated with the outside through the spout 19, and are in a carrying state;

b. the second air outlet 27 is located at the spout 19 and is communicated with the outside, and is in a dry heating state;

c. the first exhaust hole 20 is positioned at the kettle mouth 19 and communicated with the outside, and is in a steam heating state at the moment;

therefore, after the inner cylinder assembly and the kettle body assembly are combined, the inner cylinder assembly can be rotated, and the corresponding relation between the pointer 28 and the state mark 26 is referred, so that the cylinder assembly and the kettle body assembly can be quickly adjusted to a required combined state.

Further, as shown in fig. 5, 6, 19 and 20, in the aforementioned multipurpose portable electric kettle, the combination state of the inner cylinder assembly and the kettle body assembly can only be judged by observation, even though a pointer 28 and a state identifier 26 which can be matched are added, the observation is only more convenient, and for improving the accuracy when the inner cylinder assembly and the kettle body assembly are correctly combined, there is no significant improvement, that is, a positioning mechanism is lacked between the inner cylinder assembly and the kettle body assembly to ensure the accuracy of the relative positions of the inner cylinder assembly and the kettle body assembly in each state; meanwhile, the multipurpose portable electric kettle has a disadvantage that after the kettle cover assembly, the inner cylinder assembly and the kettle body assembly are combined, the three do not have a binding force for preventing the three from being separated in the axial direction, the combined state can be stably maintained only by fixing the three with the help of other objects during carrying, and the relative movement of the kettle cover assembly and the inner cylinder assembly can be promoted due to the influence of non-artificial external force during use, so that the multipurpose portable electric kettle cannot smoothly work in a dry heating state or a steam heating state. Therefore, based on the defects, the multipurpose portable electric kettle further has the following improvements:

as shown in fig. 21, 22 and 23, the cylinder edge 2 of the inner cylinder component is provided with four positioning magnetic columns 32 which are distributed at intervals in a ring shape, and the upper end surface of the kettle body component and the lower end surface of the kettle cover component are respectively and correspondingly fixed with four positioning iron sheets 33 which are distributed at intervals in a ring shape; when the kettle body assembly, the inner cylinder assembly and the kettle cover assembly are combined and in a carrying state, a dry heating state and a steam heating state, the positioning magnetic column 32 and the positioning iron sheet 33 are matched in different modes, so that corresponding axial binding force or positioning effect can be provided; in fig. 21 to 23, the positioning magnetic pillar 32 and the positioning iron piece 33 filled with black are shown to overlap to generate adsorption, and the positioning magnetic pillar 32 and the positioning iron piece 33 not filled with black are shown to be not overlapped to have no adsorption; the matching modes of the positioning magnetic column 32 and the positioning iron sheet 33 under different states are respectively as follows:

in a carrying state, as shown in fig. 21, all four positioning magnetic columns 32 are respectively overlapped with all the positioning iron sheets 33 on the upper side and the lower side one by one to generate adsorption, the first exhaust holes 20 and the second exhaust holes 27 are not positioned at the spout 19 but distributed on two sides of the spout 19, and at the moment, the pressing handle 4 of the kettle cover assembly is positioned right above the convex rib 8 of the kettle body assembly;

in the water boiling state, after the kettle body assembly and the kettle cover assembly are combined, all the positioning iron sheets 33 of the kettle body assembly and the kettle cover assembly are uniformly overlapped, but no attraction force is generated between the positioning iron sheets 33 and the positioning iron sheets 33, and the kettle cover assembly cannot be hindered from overturning;

in the dry heating state, as shown in fig. 22, the second vent hole 27 is located at the spout 19, and only one positioning magnetic column 32 is overlapped with one positioning iron sheet 33 and generates adsorption between the inner cylinder component and the kettle body component;

in the steam heating state, as shown in fig. 23, the first exhaust hole 20 is located at the spout 19, and only one positioning magnetic column 32 is overlapped with one positioning iron sheet 33 and generates adsorption between the inner cylinder component and the kettle body component;

therefore, in a carrying state, a dry heating state and a steam heating state, the positioning magnetic column 32 and the positioning iron sheet 33 are matched to generate certain adsorption force, and the adsorption force can play a positioning role to ensure that the inner cylinder assembly and the kettle body assembly can be quickly and accurately combined as required; in a carrying state, the kettle body assembly, the inner cylinder assembly and the kettle cover assembly have the maximum axial binding force mutually, so that the kettle body assembly, the inner cylinder assembly and the kettle cover assembly can be prevented from being automatically separated in the carrying process, if the multipurpose portable electric kettle is needed, the axial binding force can disappear only by enabling the inner cylinder assembly, the kettle body assembly and the kettle cover assembly to rotate relatively before the multipurpose portable electric kettle is used, and then the inner cylinder assembly, the kettle body assembly and the kettle cover assembly are easily separated; when the kettle is in a water boiling state, the kettle cover component and the kettle body component are combined and connected through the rotating mechanism 5, and the kettle cover component also needs to be capable of being turned over in use, so that additional positioning and binding are not needed to be provided between the kettle cover component and the kettle body component; in the dry heating state and the steam heating state, the kettle body component and the inner cylinder component have axial binding force, so that the kettle body component and the inner cylinder component can be prevented from moving relatively due to non-artificial external force (such as vibration), and the kettle body component and the inner cylinder component can stably work under a specific combination state, but the binding force is not large, and no overlarge obstruction can be caused to the artificial separation of the kettle body component and the inner cylinder component.

When the multipurpose portable electric kettle is used for carrying out dry heating or steam heating on objects, if the kettle cover component is required to be combined at the upper end of the inner barrel component, after the inner barrel component and the kettle cover component are combined, the kettle cover component is only required to be rotated to enable the pressing handle 4 to be positioned right above the convex rib 8, and at the moment, the inner barrel component and the kettle cover component are provided with only one positioning magnetic column 32 and one positioning iron sheet 33 which are overlapped and generate adsorption, namely, a certain binding force is provided between the inner barrel component and the kettle cover component, but overlarge obstruction can not be caused to the artificial separation of the inner barrel component and the kettle cover component.

In addition, if the technical characteristics of the positioning magnetic column 32 and the positioning iron sheet 33 are combined with the technical characteristics of the pointer 28 and the state mark 26, the combination operation of various states of the multipurpose portable electric kettle is more convenient.
