[0057] Currently, the water reservoir inside a hot water cup is usually fixed inside the cup with bolts to ensure its stability during operation. However, since the internal space of a hot water cup is usually quite small, and there are many integrated components, the bolts can easily be obstructed by other parts. This makes it inconvenient for maintenance personnel to remove the bolts, requiring the use of special tools or angles to complete the operation, reducing maintenance efficiency and increasing the workload of maintenance personnel.

[0058] Based on this, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this application embodiment provides a stable hot water cup with a multi-clamping structure, including a housing 1, a water tank 2, a heating element 3, and a lid 6; wherein, the housing 1 has an internal receiving cavity 1121, and the water tank 2 is clamped and installed in the receiving cavity 1121; as shown Figure 2 As shown, in the height direction of the housing 1, the top of the water tank 2 has an opening 22, through which water can be added to the water tank 2 or the water in the water tank 2 can be poured out; the heating element 3 is located below the water tank 2 and is attached to the bottom wall of the water tank 2. When the heating element 3 is working, it generates heat to heat the water in the water tank 2; the cover 6 is movably covered at the opening 22 and is used to open or close the opening 22.

[0059] In this embodiment, a receiving cavity 1121 is provided inside the housing 1, and the water tank 2 is clamped and installed in the receiving cavity 1121. The water tank 2 in this application is installed in the receiving cavity 1121 by clamping and fixing. Compared with the traditional installation method, it does not require a large number of bolts and other fasteners, thereby improving the convenience of disassembling and assembling the water tank 2 when maintenance personnel perform maintenance or repair. This helps to improve the efficiency of maintenance or repair of related components inside the hot water cup and reduce the workload of maintenance personnel.

[0060] In this embodiment, the heating element 3 is disposed within the receiving cavity 1121 and located at the bottom of the water tank 2. The heating element 3 is in close contact with the bottom of the water tank 2, thereby enabling the heat generated when the heating element 3 is working and generating heat to be transferred to the water in the water tank 2 through the bottom wall of the water tank 2, thus achieving the effect of heating the water in the water tank 2. It is understood that the water tank 2 needs to have good thermal conductivity, corrosion resistance, safety and a certain mechanical strength, such as stainless steel, aluminum alloy, etc. For example, the heating element 3 can be an electric heating wire, which generates heat after being energized, thereby achieving the effect of heating the water in the water tank 2.

[0061] It is understandable that a socket for connecting to an external power source is provided at a suitable location on the casing 1. The socket and the heating element 3, which is attached to the bottom wall of the water tank 2, are electrically connected by a wire. When heating is required, the socket is plugged into the external power source to supply power to the heating element 3 and achieve the heating function.

[0062] In this embodiment, the cover 6 is movably positioned over the opening 22, used to open or close the opening 22, such as... Figure 2 As shown, a sealing ring 61 is provided at the bottom of the cover 6. When the cover 6 is placed at the opening 22, the sealing ring 61 connected to the bottom of the cover 6 is inserted into the interior of the water tank 2, so that the sealing ring 61 abuts and fits against the inner wall of the water tank 2 to ensure the sealing performance of the water tank 2. At the same time, an air hole 62 is provided through the cover 6 to discharge the steam in the water tank 2 during the heating process, prevent the pressure in the water tank 2 from being too high, and thus ensure the safe operation of the equipment.

[0063] Reference Figure 5 , Figure 8 , Figure 9 As shown, in one embodiment of this application, a clamping space 1121a is formed on the circumferential inner sidewall above the receiving cavity 1121 in the height direction of the housing 1; as Figure 5 , Figure 8 As shown, a clamping part 21 is provided on the upper periphery of the water tank 2, extending in a direction away from the axial center line of the water tank 2. The clamping part 21 is clamped in the clamping space 1121a and is used to position the water tank 2 in the receiving cavity 1121.

[0064] In this embodiment, a clamping part 21 is provided on the periphery of the upper end of the water tank 2. When the water tank 2 is placed in the receiving cavity 1121, the clamping part 21 is clamped in the clamping space 1121a, thereby fixing the water tank 2 in the receiving cavity 1121. This avoids the inconvenience of disassembly and assembly caused by the traditional method of fixing and installing with bolts and other fasteners. When it is necessary to remove the water tank 2 from the housing 1, the maintenance personnel only need to open the clamping space 1121a to release the clamping and fixing of the clamping part 21 on the periphery of the upper end of the water tank 2. This allows for quick disassembly and assembly of the water tank 2, improving the work efficiency of the maintenance personnel. At the same time, by avoiding the operation of disassembling bolts and other operations in the relatively small space of the housing 1, the workload of the maintenance personnel is also significantly reduced.

[0065] It is understood that the inner circumferential dimensions and contour of the receiving cavity 1121 should be matched with the outer circumferential dimensions and contour of the water tank 2. Thus, when the water tank 2 is placed in the receiving cavity 1121, the outer circumferential wall of the water tank 2 can fit and contact the inner circumferential side of the receiving cavity 1121, thereby improving the limiting effect on the water tank 2 and ensuring the stability of the water tank 2 installed in the receiving cavity 1121. In this embodiment, when the clamping part 21 is clamped in the clamping space 1121a, the bottom of the water tank 2 abuts against the bottom of the receiving cavity 1121. For example, an abutment post extending along the height direction of the housing 1 can be provided on the bottom wall of the water tank 2 or the receiving cavity 1121. When the water tank 2 is installed in the receiving cavity 1121, a cavity is formed between the bottom wall of the water tank 2 and the bottom wall of the receiving cavity 1121. This cavity is used to install the heating element 3.

[0066] Reference Figure 1 , Figure 2 , Figure 8 As shown, in one embodiment of this application, the housing 1 includes a housing 11 and an upper cover 12; wherein, a receiving cavity 1121 is formed inside the housing 11, and the upper cover 12 is disposed on the top of the housing 11, for forming the aforementioned clamping space 1121a between the top of the housing 11 and the upper cover 12; as Figure 6 As shown, in the height direction of the housing 1, the upper cover 12 is provided with a through hole 121. When the upper cover 12 is placed on the top of the housing 11, at least part of the bottom of the cover 6 can be inserted into the interior of the water tank 2 through the through hole 121 to achieve a seal on the opening 22.

[0067] In this embodiment, when the water tank 2 is placed in the receiving cavity 1121, the clamping part 21 provided on the upper periphery of the water tank 2 is clamped in the clamping space 1121a, and under the clamping action between the upper end cover 12 and the top of the shell 11, the water tank 2 is clamped and fixed in the receiving cavity 1121; compared with the traditional method of fixing and installing with fasteners such as bolts, there is no need to use fasteners such as bolts, which reduces the difficulty of operation for maintenance personnel to remove the water tank 2.

[0068] In this embodiment, the upper end cover 12 can be fixedly installed on the housing 11 by bolts or other fasteners, or it can be snapped into the housing 11; for example Figure 8 As shown, when the water tank 2 needs to be removed, the maintenance personnel only need to remove the upper cover 12 from the housing 11 and remove it, thereby opening the clamping space 1121a. The maintenance personnel can then remove the water tank 2 from the receiving cavity 1121, thus quickly completing the disassembly process of the water tank 2. It can be understood that the upper cover 12 only covers the top of the housing 11 (and does not extend into the receiving cavity 1121). Therefore, regardless of whether bolts or snap-fit ​​connections are used, the maintenance personnel can easily complete the disassembly process of the upper cover 12. After the maintenance personnel remove the upper cover 12 from the top of the housing 11, the clamping space 1121a can be opened. The clamping part 21 on the upper periphery of the water tank 2 is no longer clamped by the upper cover 12, and the water tank 2 can be removed from the receiving cavity 1121. This greatly improves the convenience of the maintenance personnel in disassembling and assembling the water tank 2 and reduces the operational difficulty of the maintenance personnel when disassembling the water tank 2.

[0069] Reference Figure 7 , Figure 8 As shown, in one embodiment of this application, the housing 11 includes an outer shell 111 and a cylindrical frame 112; wherein, the cylindrical frame 112 is fixedly installed inside the outer shell 111, and the internal space of the cylindrical frame 112 constitutes the aforementioned receiving cavity 1121, as shown. Figure 4 As shown, in the height direction of the housing 1, an annular groove 1122 is formed at the upper end of the cylindrical frame 112, and the periphery of the annular groove 1122 facing the water tank 2 communicates with the receiving cavity 1121, so that the clamping part 21 provided on the upper periphery of the water tank 2 can synchronously enter the annular groove 1122 as the water tank 2 moves in the receiving cavity 1121; as Figure 9 As shown, when the upper end cover 12 is placed on the top of the housing 11, the space between the annular groove 1122 and the upper end cover 12 constitutes the clamping space 1121a.

[0070] In this embodiment, as Figure 8 As shown, when the water tank 2 is placed in the receiving cavity 1121, the lower end face of the clamping part 21 located on the upper periphery of the water tank 2 presses against the bottom wall of the annular groove 1122. When the upper end cover 12 is placed on the top of the housing 11, the bottom wall of the upper end cover 12 presses against the upper end face of the clamping part 21, thereby clamping and fixing the clamping part 21 in the clamping space 1121a and fixing the water tank 2 in the receiving cavity 1121.

[0071] In this embodiment, as Figure 4As shown, the cylindrical frame 112 needs to have strong structural strength to ensure that the overall boiling cup has a strong structural strength. The material of the cylindrical frame 112 can be stainless steel, aluminum alloy, etc. It can be understood that in order to achieve the overall lightweighting of the boiling cup, multiple through holes can be provided on the periphery of the cylindrical frame 112, so that the cylindrical frame 112 forms a mesh-like frame structure, thereby reducing the weight of the cylindrical frame 112 and helping to achieve the lightweight design of the boiling cup.

[0072] Reference Figure 4 , Figure 8 , Figure 9 As shown, in one embodiment of this application, the outer periphery of the upper end face of the cylindrical frame 112 has an upwardly extending annular protrusion 1123, so that the upper end face of the cylindrical frame 112 located inside the annular protrusion 1123 forms the aforementioned annular groove 1122. The height of the annular protrusion 1123 is consistent with the thickness of the clamping portion 21, thereby ensuring that when the clamping portion 21 is located within the aforementioned annular groove 1122, the upper surface of the clamping portion 21 remains flush with the upper surface of the annular protrusion 1123; as Figure 8 As shown, the bottom wall of the upper end cover 12 has a first annular portion 122 and a second annular portion 123 arranged in a stepped manner. In the height direction of the housing 1, the first annular portion 122 is located below the second annular portion 123 and is located outside the second annular portion 123. When the upper end cover 12 is placed on the top of the housing 11, the first annular portion 122 presses against the upper surface of the housing 111, and the second annular portion 123 presses against the annular protrusion 1123 and the upper surface of the extension, thereby further improving the installation stability between the upper end cover 12 and the housing 11.

[0073] In this embodiment, as Figure 8 As shown, when the clamping part 21 located on the upper periphery of the water tank 2 is located in the annular groove 1122, the outer periphery of the clamping part 21 away from the water tank 2 abuts against the inner wall of the annular protrusion 1123. Under the clamping action of the upper end cover 12, the clamping part 21 can further improve the stability of the water tank 2 in the receiving cavity 1121 and improve the positioning effect of the water tank 2.

[0074] In this embodiment, the bottom of the upper cover 12 is configured with a first annular portion 122 and a second annular portion 123 arranged in a stepped manner, and the cooperation with the annular protrusion 1123 makes the inner circumferential side of the first annular portion 122 abut against the outer circumferential side of the annular protrusion 1123 when the upper cover 12 is placed on the top of the housing 11. Thus, the blocking cooperation between the first annular portion 122 and the annular protrusion 1123 achieves the limitation of the upper cover 12 relative to the housing 11, which can further improve the installation stability between the upper cover 12 and the housing 11.

[0075] Reference Figure 8 , Figure 9 As shown, in one embodiment of this application, the second annular portion 123 is at least partially concave upward to form an annular cavity 1231, which can appropriately reduce the weight of the upper end cap 12 and help to achieve a lightweight design of the entire hot water cup; at the same time, while setting the above-mentioned annular cavity 1231, attention should be paid to ensuring that the second annular portion 123 can at least partially press against the upper surface of the clamping portion 21 to achieve clamping and positioning of the clamping portion 21.

[0076] Reference Figure 2 , Figure 3 , Figure 6 As shown, in one embodiment of this application, the upper cover 12 has an operating part 124 on one axial side, and the operating part 124 is connected to the outer shell 111 by fasteners. Various control buttons are integrated on the operating part 124 for user operation and control of the hot water cup. Due to the arrangement of the operating part 124, the upper cover 12 has excess area for fixed connection with the outer shell 111 via fasteners; for example... Figure 6 As shown, the operating part 124 is provided with multiple bolts, and the housing 11 has threaded holes at corresponding positions for threaded installation with the bolts, thereby achieving a fixed connection between the side of the upper end cover 12 with the operating part 124 and the housing 11 by bolt fastening.

[0077] In this embodiment, as Figure 6 As shown, a panel is detachably provided on the upper surface of the upper cover 12. The panel is provided with a display screen and some operation buttons. The panel and the upper cover 12 can be connected by snap-fit ​​or by adhesive.

[0078] In this embodiment, the side of the upper cover 12 away from the operating part 124 is snapped into the housing 11. Since there is no extra area on the side of the upper cover 12 away from the operating part 124 for connecting and fixing with the housing 11 by fasteners, the upper cover 12 and the housing 11 are connected and fixed in this area by snap-fit. Thus, the upper cover 12 is fixedly installed on the top of the housing 11 by fasteners and snap-fit ​​connection, ensuring the connection stability between the upper cover 12 and the housing 11.

[0079] Reference Figure 6 , Figure 10 As shown, in one embodiment of this application, the bottom of the upper cover 12 and the side away from the operating part 124 have a downwardly extending snap-fit ​​plate 125, and the snap-fit ​​plate 125 has a snap-fit ​​groove 1251 on the side opposite to the operating part 124; as Figure 6As shown, the snap-fit ​​plate 125 is connected to the bottom of the upper cover 12 and extends downward. For example, the number of snap-fit ​​plates 125 can be multiple, and the multiple snap-fit ​​plates 125 are all arranged on the side of the upper cover 12 away from the operating part 124, that is, the side opposite to the position of the operating part 124, so as to realize the snap-fit ​​connection between the side of the upper cover 12 away from the operating part 124 and the housing 11, so as to ensure the connection stability between the upper cover 12 and the housing 11.

[0080] In this embodiment, as Figure 10 As shown, the top of the housing 11 has a downwardly recessed groove 13 for accommodating the aforementioned snap-fit ​​plate 125. The number of grooves 13 is the same as the number of snap-fit ​​plates 125. This allows the snap-fit ​​parts connected to the bottom of the upper cover 12 to be inserted into the corresponding grooves 13 when the upper cover 12 is placed on top of the housing 11, and the snap-fit ​​plates 125 are snapped into the corresponding grooves 13. This achieves a snap-fit ​​connection between the side of the upper cover 12 away from the operating part 124 and the housing 11, ensuring the connection stability between the upper cover 12 and the housing 11.

[0081] In this embodiment, the groove 13 includes a first slot 131 and a second slot 132 that are connected together; for example Figure 4 As shown, the first slot 131 is located on the outer periphery of the cylindrical frame 112, and the upper end of the first slot 131 extends upward through the upper end face of the cylindrical frame 112; as shown Figure 13 As shown, a second slot 132 is formed on the inner circumferential side of the outer shell 111, and the upper end of the second slot 132 extends upward through the upper end face of the outer shell 111; when the cylindrical frame 112 is installed in a predetermined position inside the outer shell 111, the first slot 131 and the second slot 132 are combined to form the aforementioned groove 13, and the upper end of the groove 13 is connected to the outside, so that the snap-fit ​​plate 125 connected to the bottom of the upper end cover 12 can enter the aforementioned groove 13.

[0082] In this embodiment, as Figure 6 As shown, the snap-fit ​​plate 125 has a snap-fit ​​groove 1251 on the side opposite to the water tank 2; as Figure 10 As shown, a snap-fit ​​block 133 is provided on the side wall of the second slot away from the water tank 2. When the upper end cover 12 is placed on top of the housing 11, as... Figure 10 , Figure 13 As shown, the bottom of the snap-fit ​​block 133 is pressed against the bottom wall of the snap-fit ​​groove 1251. Thus, under the blocking action of the snap-fit ​​block 133 and the snap-fit ​​groove 1251, the snap-fit ​​plate 125 is snapped into the groove 13, thereby achieving a snap-fit ​​connection between the side of the upper end cover 12 away from the operating part 124 and the housing 11, ensuring the stability of the connection between the upper end cover 12 and the housing 11.

[0083] Reference Figure 6 , Figure 10 , Figure 13 As shown, in one embodiment of this application, in the height direction of the housing 1, the bottom of the snap-fit ​​plate 125 has a first inclined surface 1252, and the top of the snap-fit ​​block 133 has a second inclined surface 1331; in the height direction of the housing 1, from top to bottom, both the first inclined surface 1252 and the second inclined surface 1331 extend towards the water tank 2; by providing the first inclined surface 1252 at the bottom of the snap-fit ​​plate 125 and the second inclined surface 1331 at the top of the snap-fit ​​block 133, it is achieved that while the upper end cover 12 is placed on the top of the housing 11, the snap-fit ​​plate 125 is simultaneously driven downward into the groove 13, and the snap-fit ​​plate... The first inclined surface 1252 at the bottom of the 125 contacts the second inclined surface 1331 at the top of the snap-fit ​​block 133. Under the guiding action of the first inclined surface 1252 and the second inclined surface 1331, the snap-fit ​​plate 125 is forced to deform in a direction away from the snap-fit ​​block 133. When the bottom of the upper end cover 12 presses against the top of the housing 11, the snap-fit ​​groove 1251 moves to the position corresponding to the snap-fit ​​block 133. At this time, the snap-fit ​​plate 125 is no longer squeezed by the snap-fit ​​block 133 and recovers its deformation in a direction away from the water tank 2, thereby causing the snap-fit ​​block 133 to snap into the snap-fit ​​groove 1251 (e.g., Figure 10 (as shown), thereby achieving a snap-fit ​​connection between the upper cover 12 and the housing 11.

[0084] In this embodiment, by providing a second inclined surface 1331 at the top of the snap-fit ​​block 133 and a first inclined surface 1252 at the bottom of the snap-fit ​​plate 125, the snap-fit ​​plate 125 can smoothly enter the groove 13 as the upper end cover 12 moves, thereby achieving the snap-fit ​​engagement between the snap-fit ​​block 133 and the snap-fit ​​groove 1251, which is used to snap-fit ​​the side of the upper end cover 12 away from the operating part 124 to the housing 11.

[0085] Reference Figure 7 , Figure 11 , Figure 12 As shown, in one embodiment of this application, the heating element 3 includes a ceramic substrate 31, a DC heating wire 32, and an AC heating wire 33. The ceramic substrate 31 is fixedly connected to the bottom wall of the water tank 2. For example, an adhesive 7 can be provided between the ceramic substrate 31 and the bottom wall of the water tank 2 to bond and fix the ceramic substrate 31 to the bottom wall of the water tank 2. The adhesive 7 can be cured silicone. Cured silicone can remain stable at high temperatures and has good electrical insulation properties, which can prevent leakage and improve safety. Cured silicone also has good high-temperature thermal conductivity. It is understood that before bonding, the bottom wall of the water tank 2 and the surface of the ceramic substrate 31 need to be thoroughly cleaned to remove oil, dust and other impurities. Alcohol or special cleaning agents can be used for cleaning.

[0086] In this embodiment, the heating element 3 also includes a DC heating wire 32 and an AC heating wire 33, such as Figure 12 As shown, DC heating wire 32 and AC heating wire 33 are respectively disposed on both sides of ceramic substrate 31. It can be understood that DC heating wire 32 and AC heating wire 33 can be fixed on ceramic substrate 31 by adhesive bonding, such as high-temperature adhesive; or by sintering process (before sintering ceramic substrate 31, the heating wire is arranged inside the powder raw material of ceramic substrate 31, and the heating wire is fixed inside ceramic substrate 31 through the sintering process). In this solution, there is no restriction on the fixing method between heating wire and ceramic substrate 31, and any feasible fixing method can be used for fixing.

[0087] In this embodiment, as Figure 3 As shown, the housing 11 is equipped with a DC socket 4 electrically connected to the DC heating wire 32 and an AC socket 5 electrically connected to the AC heating wire 33. The DC socket 4 and AC socket 5 are connected to an external power connector to supply power to the DC heating wire 32 or the AC heating wire 33, thereby heating the water in the water tank 2. It can be understood that by setting up the matching AC socket 5, AC heating wire 33 and DC socket 4, DC heating wire 32, the hot water cup can be used with a 220V household AC power supply or a 12-24V DC vehicle power supply, thereby significantly improving the applicability of the hot water cup.

[0088] Understandably, the outer casing 111 should have sockets corresponding to the DC socket 4 and AC socket 5, so that external power connectors can be inserted into the DC socket 4 or AC socket 5. In order to prevent external debris from entering the DC socket 4 or AC socket 5 when not heating, a sealing plug can be inserted into the socket to block the socket; when heating is required, the sealing plug can be removed from the socket.

[0089] In this embodiment, as Figure 11 As shown, a temperature measuring element 8 is also provided on the ceramic substrate 31. The temperature measuring element 8 is bonded and fixed to the ceramic substrate 31 by an adhesive 7, and is used to detect the heating temperature in real time. For example, the temperature measuring element 8 can be a thermistor (NTC), which is a resistive element made of semiconductor ceramic material. Its resistance value decreases as the temperature increases, and it is used for temperature measurement. The hot water cup is equipped with a control circuit board and related control modules, such as a temperature sensor module (connected to the temperature measuring element 8), a user input module, a display module, a safety protection module, etc. All of the above modules are connected to the control circuit board, and coordinate and manage the normal operation of the entire device under the action of the control circuit board. Since the above control circuit board and related control modules are all existing technologies, they will not be described in detail here.

[0090] In this embodiment, a storage battery can be installed in a suitable location inside the housing 11 to provide necessary power to the display screen and control buttons on the operation unit 124. The storage battery can be connected to an external DC power source and charged through the DC socket 4.

[0091] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
