Detailed Implementation

[0033] One of the core features of this invention is a heating base for beverage containers, the structural design of which facilitates the detection of the beverage container's position.

[0034] Another key aspect of this invention is to provide a heat preservation and heating device that includes the aforementioned heating base.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the position-triggered temperature control base provided in an embodiment of the present utility model. Figure 2 An exploded view of the position-triggered temperature control base provided in an embodiment of this utility model.

[0037] The first embodiment of this utility model discloses a heating base 1 for a beverage container 2, the heating base 11 including a heating component, a detection component 150 and a control component 160.

[0038] The heating assembly includes a base 110, a power supply, a heating element 120, and a temperature sensor 130. The power supply is electrically connected to both the heating element 120 and the temperature sensor 130. The power supply can be a built-in battery 190 or an external power source, such as a vehicle power supply or the power grid. The heating element 120 and / or the temperature sensor 130 are flexibly mounted on the base 110. When the beverage container 2 is placed on the base 110, the heating element 120 and / or the temperature sensor 130 can move relative to the base 110. The temperature sensor 130 is used to detect the temperature of the beverage container 2.

[0039] Depending on the structure of the beverage container 2 and the different ways in which the beverage container 2 and the heating base 1 cooperate, for example, the beverage container 2 can be an open container or a covered container, and the heating base 1 can cooperate with the beverage container 2 only through its own top, or the heating base 1 can be provided with a mating groove that can accommodate at least part of the beverage container 2. The opening of the mating groove for the beverage container 2 to enter and exit can be the side or top of the heating base 1. Based on the different ways in which the beverage container 2 and the heating base 1 cooperate, the heating device 120 and the temperature sensor 130 can be set in different positions relative to the beverage container 2. For example, the heating device 120 can be set on the top of the heating base 1 or on the wall or bottom of the mating groove. In this way, the heating device 120 can be located on the side and / or bottom of the beverage container 2. Similarly, the temperature sensor 130 can be set on the top of the heating base 1 or on the wall, top, or bottom of the mating groove. In this way, the temperature sensor 130 can be located at at least one of the three locations: the top, side, and bottom of the beverage container 2.

[0040] The detection component 150 is used to detect the movement of the heating device 120 and / or the temperature sensor 130 relative to the base 110 to a preset position and generate a detection signal. At the preset position, the temperature sensor 130 keeps in contact with the beverage container 2. The detection component 150 includes, but is not limited to, a proximity switch and a micro switch 153, wherein the proximity switch includes, but is not limited to, a capacitive proximity switch, a Hall effect proximity switch, and a photoelectric proximity switch.

[0041] The control component 160 is electrically connected to the power supply, the heating device 120 and the detection component 150 respectively. When the detection component 150 generates a detection signal, the control component 160 controls the heating device 120 to work, that is, connects the power supply and the circuit of the heating device 120.

[0042] In application, when the beverage container 2 is placed on the base 110, the beverage container 2 pushes the heating device 120 and / or the temperature sensor 130 to move relative to the base 110. When the heating device 120 and / or the temperature sensor 130 move to the preset position, it indicates that the beverage container 2 and the heating base 1 are installed in place. The detection component 150 sends a detection signal to the control component 160. After the control component 160 obtains the detection signal, it controls the heating device 120 to work.

[0043] Compared with the prior art, the heating base 1 provided in this embodiment of the utility model uses a detection component 150 disposed within the heating base 1 to detect the movement of the heating device 120 and the temperature sensor 130 to determine whether the beverage container 2 has been placed in the correct position. This positioning detection method does not limit the materials of the heating base 1 and the beverage container 2, allowing for a wider range of material selection for the heating base 1 and the beverage container 2. This avoids limitations on the material selection and application scenarios of the heat preservation and heating equipment, and enables the production of products at various price levels to meet the needs of different users.

[0044] In this embodiment, the control component 160 is electrically connected to the temperature sensor 130. When the detection component 150 generates a detection signal, i.e., when the beverage container 2 is placed in position, the control component 160 controls the temperature sensor 130 to detect the temperature of the beverage container 2. When the temperature sensor 130 detects that the temperature of the beverage container 2 is lower than a preset temperature value, the control component 160 controls the heating device 120 to start. When the temperature of the beverage container 2 is detected to exceed the preset temperature value, the control component 160 turns off the heating device 120. That is, the control component 160 controls the heating device 120 to start only when the detection component 150 generates a detection signal and the detection value of the temperature sensor 130 is lower than the preset temperature value.

[0045] It should be noted that the above-mentioned preset temperature value can be a factory setting, that is, the preset temperature value is fixed and cannot be adjusted. Of course, it can also be adjustable, and the user can manually input the preset temperature value into the control component 160. An input device can be set on the heating base 1. The input device includes, but is not limited to, buttons or touch screens set on the heating base 1, or a mobile app. The user can connect to the control component 160 of the heating base 1 via Wi-Fi, Bluetooth or Zigbee through the mobile app. In this way, the heat preservation temperature can be adjusted according to different user needs, thereby meeting the needs of different user groups.

[0046] It is foreseeable that when the beverage container 2 is removed from the heating base 1, the heating device 120 and / or the temperature sensor 130 will have difficulty resetting themselves from the position after being pushed. Therefore, in one embodiment of this application, the heating device 120 and / or the temperature sensor 130 are disposed on the base 110 by an elastic member, which is used to reset the heating device 120 and / or the temperature sensor 130 from the position after being pushed by the beverage container 2.

[0047] Specifically, as shown in the figure, a limiting part 133 is provided between the main body 131 and the detection end 132 of the temperature sensor 130, and a first elastic reset member 140 is provided between the limiting part 133 and the base 110, such as... Figure 2 and Figure 3 As shown, the first elastic reset member 140 is a compression spring, which is sleeved on the body 131 of the temperature sensor 130. The two ends of the compression spring abut against the limiting part 133 and the base 110, respectively.

[0048] like Figure 1 and Figure 3 As shown, in one embodiment of this application, the temperature sensor 130 and the heating device 120 are both located on the top of the base 110. In order to ensure that the temperature sensor 130 can contact the beverage container 2, when the beverage container 2 is not placed on the base 110, under the action of the first elastic reset member 140, the detection end 132 of the temperature sensor 130 is at a higher height than the heating device 120. Thus, when the beverage container 2 is placed on the base 110, the detection end 132 of the temperature sensor 130 contacts the beverage container 2 before the heating device 120, and under the action of the beverage container 2, it overcomes the elastic force of the first elastic limiting member to push the temperature sensor 130.

[0049] To reduce the volume of the heating base 1, in one specific embodiment of this application, the heating device 120 is provided with a through hole through which the detection end 132 of the temperature sensor 130 passes. The limiting part 133 abuts against the heating device 120 under the action of the first elastic reset member 140. The limiting part 133 cooperates with the heating device 120 to limit the temperature sensor 130, thereby preventing the temperature sensor 130 from extending too far relative to the heating device 120, thus reducing the probability of the temperature sensor 130 being hit by the beverage container 2 during the process of placing the beverage container 2 on the heating base 1.

[0050] It is foreseeable that since the beverage container 2 contains liquid, liquid spillage is inevitable during the process of handling the beverage container 2. In order to protect the electronic components inside the heating base 1, in one embodiment of this application, such as... Figure 3As shown, a first sealing structure 180 is provided between the heating device 120 and the detection end 132 of the temperature sensor 130. The first sealing structure 180 is used to seal the gap between the detection end 132 of the temperature sensor 130 and the heating device 120. Specifically, the first sealing structure 180 includes a mounting base 181 and an O-ring 182. The mounting base 181 surrounds the detection end 132 of the temperature sensor 130 and is disposed on the heating device 120. An annular groove is formed between the mounting base 181 and the heating device 120. The O-ring 182 is disposed in the annular groove and is clamped to the detection end 132 of the temperature sensor 130.

[0051] To further optimize the above technical solution, in this embodiment, both the heating device 120 and the temperature sensor 130 can move relative to the base 110, and the heating device 120 and the temperature sensor 130 can move in the same direction relative to the base 110. In the above embodiment, the purpose of moving the heating device 120 relative to the base 110 is not to trigger the detection component 150, but to compensate for the tolerances generated during the processing and production process. That is, because the beverage container 2 and the heating base 1 inevitably have tolerances during the production process, in order to ensure that the beverage container 2 and the heating base 1 can cooperate, the movement of the heating device 120 relative to the base 110 can adaptively compensate for the tolerances of the beverage container 2 and the heating base 1. Therefore, in the above embodiment, the travel distance of the heating device 120 relative to the base 110 is usually less than the travel distance of the temperature sensor 130 relative to the base 110.

[0052] To ensure that the heating device 120 can be reset in a timely manner, such as Figure 2 and Figure 3 As shown, in one embodiment of this application, a second elastic reset member 125 is provided between the heating device 120 and the base 110. Since the heating device 120 needs to be in complete contact with the bottom of the beverage container 2, the area of ​​the heating device 120 is relatively large. To ensure that the heating device 120 can reset stably and quickly, as shown... Figure 2 As shown, multiple second elastic reset members 125 are spaced apart along the circumferential direction.

[0053] To ensure a seal between the heating device 120 and the base 110, and to prevent dust and spilled liquid from affecting the electronic components inside the heating base 1, a second sealing structure is provided between the heating device 120 and the base 110 in this embodiment. The second sealing structure is used to seal the gap between the heating device 120 and the base 110. Figure 2 and Figure 3 As shown, the second sealing structure is an elastic sealing ring 170. While sealing the gap between the heating device 120 and the base 110, the elastic sealing ring 170 allows the heating device 120 and the base 110 to move relative to each other by a preset distance.

[0054] like Figure 2 As shown in a specific embodiment of this application, the heating device 120 includes a heat-conducting contact 121, a heating element 122, an insulating element 123, and a heat-insulating pad 124. The insulating element 123 is used to insulate the heating element 122 from other components. The heating element 122 includes, but is not limited to, resistance wire, heating film, etc. The heat-conducting contact 121 is used to directly contact the beverage container 2 and is made of a material with good thermal conductivity and a certain degree of rigidity, including, but not limited to, aluminum alloy, stainless steel, etc. The heat-insulating pad 124 is used to prevent the heat generated by the heating element 122 from being transferred downwards and to ensure that the heat generated by the heating element 122 is transferred upwards as much as possible. The heat transfer ensures thermal efficiency and saves energy while preventing the internal temperature of the heating base 1 from becoming too high, thus protecting the power supply, detection component 150, and control component 160 and extending their service life. The power supply, temperature sensor 130, detection component 150, and control component 160 are located inside the base 110. The heat conduction contact 121, heating element 122, insulation element 123, and heat insulation pad 124 are stacked sequentially from top to bottom on the top of the base 110. The surface of the heat conduction contact 121 away from the heating element 122 is the heat conduction contact surface.

[0055] The through hole on the heating device 120 through which the detection end 132 of the temperature sensor 130 passes is formed by connecting a first through portion 1211 on the heat conduction contact 121, a second through portion 1221 on the heating element 122, a third through portion 1231 on the insulating element 123, and a fourth through portion 1241 on the heat insulation pad 124. The shapes of the first through portion 1211, the second through portion 1221, the third through portion 1231, and the fourth through portion 1241 can be the same or different, such as... Figure 2 As shown, in this embodiment, for ease of assembly, the second through portion 1221, the third through portion 1231 and the fourth through portion 1241 are all U-shaped grooves, and for ease of sealing, the first through portion 1211 is a hole.

[0056] like Figure 2 and Figure 3 As shown, the base 110 includes a housing base 111 and a bracket 112. The bracket 112 is detachably disposed inside the housing base 111. The bracket 112 and the housing base 111 form an accommodating space for accommodating a power supply, a temperature sensor 130, a detection component 150, and a control component 160. The heating device 120 is disposed on the top of the bracket 112. The first elastic reset member 140 is disposed between the temperature sensor 130 and the bracket 112, and the second elastic reset member 125 is disposed between the heating device 120 and the bracket 112.

[0057] like Figure 3As shown, the base 110 with this split structure also provides convenient adjustment for fixing the elastic sealing ring 170. The top of the bracket 112 is provided with an annular boss, and the outer side of the elastic sealing ring 170 is provided with an annular groove that matches the annular boss. The annular groove and the annular boss cooperate, and the shell base 111 cooperates with the bracket 112 to clamp the elastic sealing ring 170. The inner side of the elastic sealing ring 170 is provided with a snap-fit ​​groove for snapping with the edge of the heat conduction contact 121. In order to increase the snap-fit ​​strength between the elastic sealing ring 170 and the heat conduction contact 121, the edge of the heat conduction contact 121 is provided with a flange with a Z-shaped cross section. The flange partially or completely snaps with the snap-fit ​​groove.

[0058] To improve the stability of the fit between the heating element 120 and the elastic sealing ring 170, such as Figure 2 As shown, one of the heat conduction contact 121 and the elastic sealing ring 170 is provided with a limiting protrusion at intervals along the circumference, and the other of the heat conduction contact 121 and the elastic sealing ring 170 is provided with a limiting groove at intervals along the circumference. The limiting protrusion and the limiting groove cooperate to fix the heat conduction contact 121 and the elastic sealing ring 170 relatively in the circumferential and axial directions.

[0059] like Figure 2 and Figure 3 As shown in this embodiment, the detection component 150 includes a micro switch 153 and a trigger 151. The trigger 151 is disposed on the temperature sensor 130 and / or the heating device 120 to touch the micro switch 153, causing the micro switch 153 to send a detection signal to the control component 160. Please refer to [link to relevant documentation]. Figure 2 The trigger 151 is an L-shaped component. The horizontal arm of the L-shaped component is sleeved on the temperature sensor 130, and the vertical arm of the L-shaped component extends downward along the temperature sensor 130 to serve as the trigger end to touch the micro switch 153.

[0060] like Figure 2 As shown, the control assembly 160 includes a control board, which is located below the temperature sensor 130 and the bracket 112. A micro switch 153 is located on the control board. When the L-shaped component moves downward with the temperature sensor 130, the end of the longitudinal arm of the L-shaped component touches the micro switch 153, forming a detection signal.

[0061] Furthermore, in order to reduce hard contact between the trigger 151 and the micro switch 153, a flexible sleeve 152 is provided on the end of the trigger 151 near the micro switch 153. The flexible sleeve 152 includes, but is not limited to, a silicone sleeve.

[0062] This application also provides a heat preservation and heating device, such as... Figure 3 and Figure 4As shown, the heat preservation and heating device includes a beverage container 2 and a heating base 1. The heating base 1 is the same as described in the above embodiment. Since this heat preservation and heating device uses the heating base 1 described in the above embodiment, the technical effect of this device can be referred to the above embodiment. The above-mentioned heat preservation and heating device includes, but is not limited to, mugs, electric hot pots, soy milk makers, and blenders.

[0063] To further optimize the above technical solution and improve the stability of the connection between the beverage container 2 and the heating base 1, a snap-fit ​​structure is provided between the beverage container 2 and the heating base 1, such as... Figure 3 and Figure 4 As shown, the bottom of the beverage container 2 is provided with an assembly groove, and a plurality of first snap-fit ​​protrusions 210 are provided at intervals on the inner peripheral wall of the assembly groove. The first snap-fit ​​protrusions 210 are inclined relative to the cross-section of the assembly groove. The top of the heating base 1 is provided with an assembly boss 1111, and a plurality of second snap-fit ​​protrusions 1112 are provided at intervals on the outer peripheral wall of the assembly boss 1111. The second snap-fit ​​protrusions 1112 are inclined relative to the cross-section of the assembly boss 1111. After the assembly groove and the assembly boss 1111 are inserted and rotated relative to each other by a preset angle, the first snap-fit ​​protrusions 210 and the second snap-fit ​​protrusions 1112 cooperate to snap-fit ​​the beverage container 2 and the heating base 1. Of course, the snap-fit ​​structure between the beverage container 2 and the heating base 1 is not limited to the above structure. The above snap-fit ​​structure is only a specific implementation method provided by the embodiment of this application. Other snap-fit ​​structures can be used in other embodiments, which are not limited here.

[0064] Furthermore, a limiting step surface 1113 is provided between the mounting boss 1111 and the heating base 1, which is used to contact and cooperate with the bottom end face of the beverage container 2.

[0065] like Figure 4 As shown, the heat preservation and heating equipment also includes a power supply base 33, which is provided with an annular electrical contact 320 for electrical connection with the power grid. The heating base 1 is provided with a mating contact for electrical connection with the power supply of the heating base 1. The annular electrical contact 320 is plugged into the mating contact.

[0066] Furthermore, the heating base 1 is provided with a battery 190 as a power source, which is used to provide power to the heating device 120, and the power supply base 33 is used to charge the battery 190.

[0067] like Figure 4As shown, the power supply base 33 is provided with an insertion slot 310, which is used to insert and cooperate with the bottom of the heating base 1. One of the two locations, the inner peripheral wall of the insertion slot 310 and the outer peripheral wall of the bottom of the heating base 1, is provided with multiple protrusions 311 along the circumferential direction. The other of the two locations, the inner peripheral wall of the insertion slot 310 and the outer peripheral wall of the bottom of the heating base 1, is provided with multiple recesses 1114 along the circumferential direction. The protrusions 311 and the recesses 1114 are engaged and cooperated.

[0068] Furthermore, such as Figure 4 As shown, the power supply base 33 is also equipped with a charging interface 330 for plugging in the charging cable. This allows the power supply base 33 and the charging cable to be designed separately, which is convenient for storage and use. If the charging cable is damaged, it can be directly replaced, which is convenient for maintenance.
