Description

Technical Field

[0001] This application relates to the field of water heating, and more specifically, to a long-lasting heating device. Background Technology

[0002] Currently, most instant hot water dispensers or long-lasting heating devices on the market use metal or ceramic heating elements to heat the liquid in the storage container. During long-term use, calcium and magnesium ions in the water easily precipitate on the surface of the heating element, forming scale. Scale buildup not only significantly reduces heat transfer efficiency and increases energy consumption, but can also cause localized overheating of the heating element, shortening its lifespan and even leading to equipment failure. Furthermore, cleaning the heating element in traditional designs relies heavily on periodic manual disassembly and cleaning or chemical descaling agents, which is cumbersome and poses a risk of secondary contamination. On the other hand, if the high-temperature water vapor generated during the heating process directly contacts the electronic control components in the top cover, it can easily lead to component aging, decreased insulation performance, or control malfunction. Utility Model Content

[0003] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] Furthermore, the cleaning component includes a cover plate; a through groove is provided on the cover plate, and an elastic cleaning structure is provided in the through groove; the heating element is inserted into the through groove; the cover plate is fastened onto the water storage bottle; the elastic cleaning structure is in close contact with the heating element.

[0006] Furthermore, the water storage bottle is provided with an upwardly protruding nozzle; a downwardly protruding cap is provided below the cap plate; the nozzle and the cap are embedded in the nozzle, and the through groove is provided on the cap.

[0007] Furthermore, the cover plate has an outwardly protruding baffle located outside the bottle mouth; a notch is provided on the bottle mouth, and the cover plate is placed on the bottle mouth, with the notch forming a pressure relief port between the bottle mouth and the cover plate.

[0008] Furthermore, the cover plate is also provided with multiple retaining plates; the retaining plates and the cover shell form retaining grooves, and the bottle mouth is embedded in the retaining grooves.

[0009] Furthermore, the bottle cap is embedded in the cap shell.

[0010] Furthermore, the elastic cleaning structure is a sponge block or an elastic rubber block.

[0011] Furthermore, multiple bumps are formed on the cleaning structure.

[0012] Furthermore, the cleaning structure is provided with multiple brush rods.

[0013] The beneficial effects of this application are as follows: By incorporating a flexible cleaning structure (such as a sponge block or elastic rubber block) within the through-slot of the cover plate, and constructing protrusions or brush rods on its surface, automatic scraping and cleaning are achieved during the insertion or removal of the heating element. This design effectively removes scale and adhering impurities from the surface of the heating element, prevents the formation of a thermal resistance layer, ensures efficient heat conduction between the heating element and water, maintains continuous heating performance, and extends the lifespan of the element.

[0014] The baffle on the cap, together with the notch at the nozzle, forms a pressure relief channel, allowing the steam generated during heating to diffuse outwards and preventing high-temperature steam from directly impacting the cap and internal electronic components (such as the control board and sensors). This structure significantly reduces the temperature rise in the control area, protecting precision electronic equipment from the effects of a humid and hot environment, thereby improving the overall reliability and operational safety of the machine.

[0015] The cap and nozzle are fitted together via a locking plate and cap shell, enhancing overall assembly stability and preventing cap displacement due to friction from the cleaning component. This design ensures the cleaning component remains in its functional position and facilitates user assembly, disassembly, and maintenance, demonstrating excellent human-machine interface engineering.

[0016] The overall structure highly integrates heating, cleaning, and control functions into the cap unit, making it compatible with various sizes of water bottles. It has strong versatility and expandability, which is conducive to product series development and market application. Attached Figure Description

[0025] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Reference Figure 1-5 , A long-lasting heating device includes: a water storage bottle 1, a cap 3, a heating element 4, and a cleaning component 5. The heating element 4 is a crystal tube used to heat water. The cleaning component 5 is used to clean the heating element 4, preventing scale buildup when it heats water, thus ensuring better heating efficiency. The cap 3 is on the water storage bottle 1; the heating element 4 is connected to the cap 3; the cap 3 houses a control board and control elements; the control elements are connected to the heating element 4 via the control board; the cleaning component 5 is disposed between the water storage bottle 1 and the cap 3, and is used to clean the heating element 4.

[0027] Specifically, the cleaning component 5 includes a cover plate 6; a through groove 72 is provided on the cover plate 6, and an elastic cleaning structure 8 is provided in the through groove 72; the heating element 4 is inserted into the through groove 72; the cover plate 6 is fastened to the water storage bottle 1; the elastic cleaning structure 8 is in close contact with the heating element 4. Utilizing the elastic cleaning structure 8, when the heating element 4 is inserted into the water storage bottle 1 from the through groove 72, the heating element 4 first passes through the elastic cleaning structure 8, and then the elastic cleaning structure 8 comes into close contact with the heating element 4. The friction between the elastic cleaning structure 8 and the heating element 4 cleans the heating element 4, thus removing dust, impurities, or scale from the heating element 4, ensuring better direct contact between the heating element 4 and the water, and improving the efficiency of water heating.

[0028] Specifically, the water storage bottle 1 has an upwardly protruding nozzle 2; the cover plate 6 has a downwardly protruding cap 71 below it; the nozzle and cap 71 are embedded in the nozzle 2, and the through groove 72 is provided on the cap 71. The bottle cap 3 is embedded in the cap 71. Thus, an elastic cleaning structure 8 can be provided on the nozzle 2, and the bottle cap 3 can be placed on the water storage bottle 1. Specifically, the elastic cleaning structure 8 is a sponge block or an elastic rubber block.

[0029] Specifically, the cover plate 6 has an outwardly protruding baffle 7 located outside the bottle mouth 2; a notch 21 is provided on the bottle mouth 2, and the cover plate 6 is located on the bottle mouth 2, with the notch 21 forming a pressure relief port between the bottle mouth 2 and the cover plate 6. With the baffle 7 in place, after water vapor overflows from the water storage bottle 1, the upward-flowing water vapor will contact the baffle 7, and then flow along the baffle 7, either upwards outside the baffle 7 or directly to the outside. This prevents high-temperature water vapor from directly or indirectly contacting the bottle cap 3, causing the bottle cap 3 to overheat, which in turn leads to overheating of the bottle cap 3's control board and control module, thus better ensuring the service life of the bottle cap 3's control board and control module.

[0030] Specifically, the cover plate 6 is also provided with multiple retaining plates 73; the retaining plates 73 and the cover shell 71 form a retaining groove 74, and the bottle mouth 2 is embedded in the retaining groove 74. Since the heating element 4 will come into contact with the cleaning structure when the bottle cap 3 is pulled out, the friction between the heating element 4 and the cleaning structure can easily drive the cover plate 6 to move upward. The retaining plates 73 are provided so that the cover plate 6 can be better positioned on the water storage bottle 1 when the bottle cap 3 is pulled out.

[0031] Specifically, the cleaning structure has multiple protrusions or multiple brush rods. The protrusions and brush rods are designed to improve the cleaning effect on the heating element 4.

[0032] Usage process The operating procedure for this long-lasting heating device is as follows: Water injection and assembly: The user injects water to be heated into the water storage bottle 1, and then fastens the cover plate 6 assembly to the bottle mouth 2, ensuring that the cover shell 71 is embedded inside the bottle mouth 2, and the clamping plate 73 structure is fitted into the notch 21 of the bottle mouth 2 to form a stable assembly.

[0033] Heating element 4 insertion and self-cleaning: The heating element 4 (crystal tube) connected to the bottle cap 3 is inserted downward into the water storage bottle 1 along the through groove 72 on the cap shell 71. During the insertion process, the surface of the heating element 4 comes into close contact and friction with the elastic cleaning structure 8 (such as a sponge block with protrusions), thereby achieving automatic scraping of scale and impurities on its surface.

[0034] Heating operation: The heating program is initiated by a control element (such as a button or touch switch) on the bottle cap 3, which controls the main board to output a signal to the heating element 4 to start working. During the heating process, the water is continuously and efficiently heated, while the cleaning element 5 remains in contact with the heating element 4 to remove any newly formed scale.

[0035] Steam Management and Depressurization: The steam generated by heating is discharged outward along the pressure relief port formed by the notch 21 of the bottle mouth 2 and the baffle 7 of the cover plate 6, preventing steam from entering the internal control area of ​​the bottle cap 3, thereby ensuring that the electronic components are in a low temperature and low humidity environment.

[0036] Removal and maintenance: After heating is complete or when water needs to be added, the user pulls the bottle cap 3 and heating element 4 upwards. During the pulling process, the cleaning component 5 performs a secondary cleaning of the surface of the heating element 4. If necessary, the user can separate the cover plate 6 assembly to clean or replace the cleaning structure to maintain the cleaning effect.

[0037] Through the above process, the device achieves fully automated integrated operation of heating, self-cleaning, and thermal management, significantly improving the product's practicality and durability.
