Description

Technical Field

[0001] This utility model generally relates to the field of electrical technology, and more specifically, to a water gauge structure for a kettle and a kettle. Background Technology

[0002] Existing kettles typically have windows to allow users to easily observe the water level inside. These windows are usually covered with transparent materials to meet this visibility requirement. However, in actual production, ordinary engineering plastics can only meet the requirements of high temperature resistance, high transparency, and good strength, but they do not meet food-grade requirements. Some materials can meet food-grade requirements, but their transparency is relatively poor and their strength is relatively low. Only a very few specialty engineering plastics can simultaneously meet all the above requirements, but these specialty engineering plastics are expensive and require sophisticated manufacturing processes. Given this situation, existing water level gauge structures require complex structures and greater thickness to ensure overall strength, resulting in higher production costs and larger window areas, which negatively impact the overall aesthetics of the kettle. Utility Model Content

[0003] This invention provides a water gauge structure for a kettle that can balance structural strength, transparency, and food-grade requirements, as well as a kettle equipped with the water gauge structure.

[0004] According to a first aspect of the present invention, an embodiment of the present invention provides a water gauge structure for a kettle, including a transparent inner water gauge and a transparent outer water gauge. The outer water gauge includes a protrusion, and the inner water gauge has a recess on the side facing the outer water gauge corresponding to the position of the protrusion. The protrusion fits into the recess.

[0005] The inner water gauge is made of food-grade material, and the outer water gauge has a greater structural strength than the inner water gauge.

[0006] In some embodiments, the transparency of the outer water gauge is greater than that of the inner water gauge.

[0007] The high transparency of the outer water gauge ensures clear water level observation for users, while the inner water gauge meets food-grade requirements, guaranteeing safety upon contact with water and complying with relevant food hygiene standards. This combination of inner and outer water gauges fully leverages the advantages of different materials, achieving a balance between ease of observation and hygiene safety.

[0008] In some embodiments, the thickness of the inner water gauge is less than the thickness of the protrusion along the thickness direction of the outer water gauge.

[0009] The thickness direction of the outer water gauge is consistent with the radial direction of the kettle when the water gauge structure is installed on the kettle.

[0010] In this way, the protruding part of the outer water gauge effectively supports the inner water gauge, improving the overall strength of the kettle's water gauge structure. At the same time, the relatively thinner inner water gauge, while meeting food-grade requirements for contact with water, reduces material costs and helps to reduce the overall thickness of the kettle's water gauge structure, improving the kettle's simplicity and aesthetics.

[0011] In some embodiments, one of the inner wall of the recess and the outer wall of the protrusion is provided with a rib, and the other is provided with a groove, wherein the rib engages with the groove.

[0012] In this method, the inner wall of the recess and the outer wall of the protrusion are interlocked by ribs and slots, achieving a reliable connection between the inner and outer water gauges. This effectively prevents relative displacement between the two water gauges during use, ensuring the structural stability of the water gauge structure. Furthermore, compared to other connection methods, this interlocking structure is easier to install and disassemble, facilitating production assembly and subsequent maintenance.

[0013] In some embodiments, the rib extends along the length of the water gauge structure;

[0014] Alternatively, the rib may include a plurality of protrusions, which are arranged at intervals along the length of the water gauge structure;

[0015] The length direction of the water gauge structure is consistent with the axial direction of the kettle when the water gauge structure is installed on the kettle.

[0016] This continuous snap-fit ​​structure allows for greater fixation between the inner and outer water gauges, further enhancing the stability of the water gauge structure in the length direction, effectively resisting forces caused by water level changes and water flow impacts, and extending the service life of the water gauge structure.

[0017] Multiple protrusions are engaged with the slots to form multiple sets of engagement points, ensuring the connection stability between the inner and outer water gauges and preventing loosening due to the failure of a single engagement point. At the same time, there is a gap between two adjacent protrusions, which can buffer slight deformation forces to a certain extent and reduce the possibility of connection failure due to deformation.

[0018] In some embodiments, the width of the protrusion is less than or equal to 6 mm along the width direction of the outer water gauge;

[0019] The width direction of the outer water gauge is consistent with the circumferential direction of the kettle when the water gauge structure is installed on the kettle.

[0020] The relatively narrow width of the protrusion achieves a narrow water level gauge design, with no structural obstruction to the viewing window. This ensures the kettle maintains visibility of the water level while minimizing the impact of the water level gauge structure on the kettle's appearance, enhancing its overall aesthetics and meeting user needs. Simultaneously, the narrow water level gauge structure saves space on the kettle body, allowing for optimized structural layout and more room for other functional components.

[0021] In some embodiments, a sealing ring is also included, which is fitted over the outside of the inner water gauge.

[0022] The sealing ring effectively prevents water from seeping out from the gap between the inner and outer water gauges, ensuring a tight seal and preventing water leakage from damaging the internal electrical components of the kettle, thus improving the safety and reliability of the kettle. Furthermore, the sealing ring also acts as a buffer, reducing wear caused by friction between the two water gauges.

[0023] In some embodiments, the outer water gauge further includes a cover portion disposed on one side of the protrusion exposed to the recess, and the protrusion extends outward from both sides of the cover portion along the width direction of the outer water gauge;

[0024] The outer wall of the inner water gauge is provided with a limiting boss, and the two sides of the sealing ring abut against the limiting boss and the cover respectively.

[0025] The width direction of the outer water gauge is consistent with the circumferential direction of the kettle when the water gauge structure is installed on the kettle.

[0026] This design allows the limiting boss to precisely position the sealing ring, ensuring its accurate placement during assembly and use, thus enhancing its sealing performance. The cover provides the mounting and abutment position for the sealing ring; both the limiting boss and the cover press against the sealing ring from both sides, ensuring its positional stability. This also prevents displacement or deformation of the sealing ring under water pressure, further improving the sealing performance and stability of the kettle's water gauge structure.

[0027] In some embodiments, the cover and the protrusion are integrally formed and are solid structures.

[0028] The lid and the protrusion are integrally molded, which reduces the number of connecting parts between them, minimizes gaps at the connection points, and improves the overall strength and stability of the kettle's water gauge structure. At the same time, the integral molding method also improves production efficiency, reduces production costs, minimizes assembly errors during production, and ensures consistent quality of the outer water gauge.

[0029] The cover and protrusions are solid structures, which further enhances the structural strength.

[0030] In some embodiments, the inner water gauge is made of PP material and the outer water gauge is made of PC material.

[0031] According to a second aspect of the present invention, an embodiment of the present invention also provides a kettle, including a kettle body and the above-mentioned kettle water level structure, wherein the kettle body is provided with a window, and the kettle water level structure is disposed in the window.

[0032] In some embodiments, the kettle body has a connecting portion that bends into the kettle body at the window position, and the water gauge structure includes a sealing ring that is fixed to the connecting portion.

[0033] This design provides strong support for the sealing ring at the connection point, further enhancing the sealing effect between the sealing ring and the kettle body window. This effectively prevents water from leaking between the kettle body window and the water gauge structure, ensuring the safety and reliability of the kettle.

[0034] One embodiment of this utility model has the following advantages or beneficial effects:

[0035] The water level gauge structure provided in this embodiment utilizes a transparent inner water level gauge and a transparent outer water level gauge to facilitate user observation of the water level inside the kettle, giving the kettle a visual water level display function. The inner water level gauge is made of food-grade material, ensuring that the food-grade material of the inner water level gauge comes into contact with water, thereby guaranteeing the user's food health and safety. The inner water level gauge has a recessed portion, and the thinner inner water level gauge can improve its transparency to a certain extent. At the same time, through the protrusion that fits into the recessed portion, the high strength of the outer water level gauge provides strong structural support for the inner water level gauge, ensuring the reliability and stability of the water level gauge structure.

[0036] The kettle provided in this embodiment has a water level indicator structure set in the window of the kettle body, which enables the kettle to have a visual water level display function, improves the overall performance of the kettle and the user experience, and makes it convenient for users to accurately grasp the water level in the kettle at any time, avoiding overflow when boiling due to adding too much water or dry burning due to adding too little water. In particular, the kettle is equipped with an automatic power-off function, which can accurately control the minimum water level, thereby improving the convenience and safety of use.

The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0056] This embodiment provides a kettle, which can be a regular kettle with only water-holding function, an electric kettle with heating function, an insulated kettle with heat preservation function, or a kettle with both heating and heat preservation functions. For example... Figures 1-2 As shown, the kettle includes a kettle body 200 and a water level gauge structure 100. The kettle body 200 may be made of stainless steel and has a window 201. The water level gauge structure 100 of the kettle is located in the window 201.

[0057] For example, the kettle body 200 has a cylindrical shape, such as a columnar structure. The kettle body 200 is hollow and has a receiving cavity 203 for holding water. The receiving cavity 203 has an open end, and a lid 205 is rotatably mounted on the top of the kettle body 200, or the lid 205 is detachably connected to the kettle body 200, allowing the lid 205 to open or close the open end. The user can add water to the receiving cavity 203 through the open end, or transfer or pour water from the receiving cavity 203 through the open end. A handle 204 may be provided on the outer wall of the kettle body 200 for easy gripping by the user.

[0058] For example, the window 201 may be a through hole provided on the body 200. For example, the shape of the through hole may be a rectangular hole, an oblong hole, an elliptical hole, etc.

[0059] The kettle provided in this embodiment features a water level gauge 100 located in the window 201 of the kettle body 200. Users can observe the water level inside the kettle body 200 through the water level gauge 100, providing a visual water level display and improving the overall performance and user experience. Users can determine the water level without opening the lid 205 of the kettle body 200, allowing for accurate monitoring of the water level at any time. This is especially beneficial for electric kettles, preventing overflow due to overfilling or dry boiling due to underfilling. For electric kettles with automatic power-off function, the minimum water level can be precisely controlled, improving ease of use and safety.

[0060] This embodiment also provides a water level gauge structure 100 for a kettle, such as... Figures 3-4 As shown, the water gauge structure 100 includes a transparent inner water gauge 1 and a transparent outer water gauge 2. The outer water gauge 2 includes a protrusion 21, and the inner water gauge 1 has a recess 11 on the side facing the outer water gauge 2, corresponding to the position of the protrusion 21. The protrusion 21 fits into the recess 11. The inner water gauge 1 is made of food-grade material, and the structural strength of the outer water gauge 2 is greater than that of the inner water gauge 1.

[0061] For example, the outer water gauge 2 is disposed outside the inner water gauge 1; or, the inner water gauge 1 is disposed on the side of the outer water gauge 2 facing the receiving cavity 203, that is, the inner water gauge 1 and the water phase in the receiving cavity 203 are in contact.

[0062] The inner water gauge 1 is made of food-grade material, such as PP material. As the part that comes into contact with water, the inner water gauge 1 meets food hygiene and safety standards, ensuring user safety. For example, the inner water gauge 1 is made of a high-temperature resistant material with a temperature resistance of not less than 100°C, ensuring its performance even when boiling water is contained in the kettle's cavity 203.

[0063] Specifically, the recessed portion 11 is provided on the side of the inner water gauge 1 facing the outer water gauge 2, which is equivalent to thinning the thickness of the inner water gauge 1 to weaken the structure. The thinner inner water gauge 1 can improve the transparency of the inner water gauge 1 to a certain extent.

[0064] Specifically, the protrusion 21 and the recess 11 cooperate, that is, the outer wall surface of the protrusion 21 contacts the inner wall surface of the recess 11. The protrusion 21 provides a certain support for the thinned inner water gauge 1, preventing the inner water gauge 1 from deforming or breaking due to water pressure and high temperature, thus improving the reliability of the kettle. At the same time, the protrusion 21 is inserted into the recess 11 to form an embedded support structure, eliminating the need for additional reinforcement structures, simplifying the design, and to a certain extent ensuring that the outer water gauge 2 and the inner water gauge 1 fit tightly together.

[0065] For example, the recessed portion 11 of the inner water gauge 1 is wrapped around the outside of the protrusion 21, so that the protrusion 21 with relatively high structural strength serves as the main strong support structure, providing a certain support force for the inner water gauge 1 and preventing the inner water gauge 1 from cracking or deforming due to insufficient strength.

[0066] The water level gauge structure 100 provided in this embodiment utilizes a transparent inner water level gauge 1 and a transparent outer water level gauge 2 to facilitate user observation of the water level inside the kettle body 200, giving the kettle a visual water level display function. The inner water level gauge 1 is made of food-grade material, ensuring that the food-grade material of the inner water level gauge 1 comes into contact with water to guarantee the health and safety of the user's food. The inner water level gauge 1 also features a recessed portion 11, and its thinner design improves its transparency to a certain extent. Simultaneously, a protrusion 21 fits into the recessed portion 11, and utilizing the high strength of the outer water level gauge 2, the protrusion 21 provides strong structural support for the inner water level gauge 1, ensuring the reliability and stability of the water level gauge structure 100.

[0067] The transparency of the outer water gauge 2 is greater than that of the inner water gauge 1.

[0068] For example, the inner water gauge 1 is made of PP material, which has the advantages of low price and food-grade compliance. Of course, the inner water gauge 1 can also be made of PP plastic material or other low-cost plastic materials that meet the requirements. PP material does not release any known hazardous substances during normal use, has high stability, meets food-grade requirements, and is resistant to high temperatures for a long time, for example, ≥100°C, and can withstand repeated boiling. This material is more suitable for the inner water gauge 1 of the kettle. Although PP material is transparent, its transparency decreases as the thickness increases.

[0069] For example, the outer water gauge 2 is made of PC material, which has the advantages of high strength, high transparency, and high temperature resistance. Of course, the outer water gauge 2 can also be made of ordinary PC plastic material or other low-cost plastic materials that meet the requirements. PC material has a relatively high light transmittance, and light is not easily refracted or deformed when it passes through, which can clearly show the water level in the kettle body 200. It also has high structural strength, is impact-resistant, and is not easy to break or crack.

[0070] The high transparency of the outer water gauge 2 ensures clear water level observation for users, while the inner water gauge 1 meets food-grade requirements, guaranteeing safety upon contact with water and meeting users' health and safety needs. This structural combination of inner and outer water gauges 1 fully leverages the advantages of different materials, achieving a balance between ease of observation and hygiene safety.

[0071] The outer water gauge 2 and the inner water gauge 1 are described below.

[0072] like Figures 3-5 As shown, the outer water gauge 2 has a shape resembling a long strip. It has at least one reference plane, which is parallel to the horizontal plane. The thickness and width directions of the outer water gauge 2 are two mutually perpendicular directions within the reference plane. The length direction of the outer water gauge 2 is perpendicular to the reference plane. Specifically, the thickness, width, and length directions of the outer water gauge 2 are mutually perpendicular to each other. The length direction of the outer water gauge 2 is denoted by D1, the width direction by D2, and the thickness direction by D3.

[0073] It should be noted that the length direction of the outer water gauge 2 is consistent with the axial direction of the kettle when the water gauge structure 100 is installed on the kettle; the thickness direction of the outer water gauge 2 is consistent with the radial direction of the kettle when the water gauge structure 100 is installed on the kettle; and the width direction of the outer water gauge 2 is consistent with the circumferential direction of the kettle when the water gauge structure 100 is installed on the kettle.

[0074] Specifically, the outer water gauge 2 also includes a cover 20, which can be called a water gauge cover. The cover 20 is similar in shape to a long strip structure. The cover 20 is provided with scale lines, such as "0.5L", "1.0L", "0.7L", etc. The cover 20 may also be provided with a maximum limit mark "MAN" to indicate the maximum water level position. The cover 20 may also be provided with a minimum limit mark "MIN" to indicate the minimum water level position.

[0075] Specifically, the cover 20 is provided on the side of the protrusion 21 exposed to the recess 11, and the protrusion 21 extends outward from both sides of the cover 20 along the width direction of the outer water gauge 2.

[0076] This design allows the cover 20 to prevent external dust and water stains from entering the mating gap between the protrusion 21 and the recess 11, reducing the risk of dirt buildup causing jamming or seal failure. The protrusions 21 extending outward from both sides of the cover 20 increase the connection strength between the cover 20 and the protrusions 21, preventing the protrusions 21 from breaking due to water pressure impact and improving the overall reliability of the outer water gauge 2 structure.

[0077] The connection between the cover 20 and the protrusion 21 can be smoothly transitioned by an arc.

[0078] At least one of the cover portion 20 and the protrusion portion 21 is a solid structure. For example, both the cover portion 20 and the protrusion portion 21 are solid structures, which further improves the structural strength.

[0079] Specifically, the cover 20 and the protrusion 21 are integrally molded. This design reduces the number of connecting parts between the cover 20 and the protrusion 21, minimizes gaps at the connection points, and improves the overall strength and stability of the water gauge structure 100. Furthermore, the integral molding method also improves production efficiency, reduces production costs, minimizes assembly errors during production, and ensures the overall consistency of the outer water gauge 2.

[0080] like Figures 3-4 and Figure 6 As shown, the inner water gauge 1 has a shape similar to a long strip structure. The structural shape of the inner water gauge 1 is adapted to the structural shape of the outer water gauge 2 to ensure the matching effect between the inner water gauge 1 and the outer water gauge 2.

[0081] In one embodiment, such as Figures 4-6 As shown, one of the inner wall of the recessed portion 11 and the outer wall of the protruding portion 21 is provided with a rib 22, and the other is provided with a groove 12. The rib 22 is engaged with the groove 12.

[0082] For example, the inner wall of the recess 11 is provided with a groove 12, and the outer wall of the protrusion 21 is provided with a rib 22. Of course, in some other embodiments, the positions of the groove 12 and the rib 22 can be interchanged.

[0083] For example, the cross-sectional shape of the rib 22 and the slot 12 can be triangular, rectangular, trapezoidal, etc.

[0084] In this manner, the inner wall of the recess 11 and the outer wall of the protrusion 21 are interlocked with the slot 12 by the rib 22, achieving a reliable connection between the inner water gauge 1 and the outer water gauge 2. This effectively prevents displacement of the two water gauges during use and ensures the structural stability of the water gauge structure 100. Furthermore, compared to other connection methods, this interlocking structure is easier to install and disassemble, facilitating production assembly and subsequent maintenance.

[0085] Among them, the rib 22 extends along the length direction of the water gauge structure 100, and the groove 12 is a continuous groove extending along the length direction of the water gauge structure 100, wherein the length direction of the water gauge structure 100 is the length direction of the outer water gauge 2.

[0086] With this design, the continuous snap-fit ​​structure can achieve fixation between the inner water gauge 1 and the outer water gauge 2 over a wider range, further enhancing the connection stability of the water gauge structure 100 in the length direction, effectively resisting the forces generated by factors such as water level changes and water flow impact, and extending the service life of the water gauge structure 100.

[0087] There are two ribs 22 and two slots 12. Along the width direction of the outer water gauge 2, the two ribs 22 are set on both sides of the protrusion 21, and the two slots 12 are set on both sides of the recess 11. The two ribs 22 are correspondingly engaged with the two slots 12.

[0088] In some other embodiments, the rib 22 includes a plurality of protrusions arranged at intervals along the length of the outer water gauge 2, and the plurality of protrusions can be engaged in a slot 12.

[0089] Alternatively, the slot 12 may include multiple sub-grooves, which are spaced apart along the length of the outer water gauge 2. Multiple protrusions engage with the multiple sub-grooves, forming multiple sets of engagement points to ensure the connection stability between the inner water gauge 1 and the outer water gauge 2, and to prevent loosening due to the failure of a single engagement point. At the same time, there are gaps between adjacent protrusions and between adjacent sub-grooves, which can buffer slight deformation forces to a certain extent and reduce the possibility of failure due to deformation.

[0090] In one embodiment, such as Figures 3-4 As shown, the water gauge structure 100 of the kettle also includes a sealing ring 3, which is fitted onto the outside of the inner water gauge 1.

[0091] In this way, the sealing ring 3 effectively prevents water from seeping out from the gap between the inner water gauge 1 and the outer water gauge 2, ensuring the seal between them and preventing water leakage from damaging the internal electrical components of the kettle, thus improving the safety and reliability of the kettle. Furthermore, the sealing ring 3 also acts as a buffer to some extent, reducing wear caused by mutual friction between the inner and outer water gauges 1 and 2.

[0092] The inner water gauge 1 has a limiting boss 13 on its outer wall, and the sealing ring 3 abuts against the limiting boss 13 and the cover 20 of the outer water gauge 2 on both sides along the thickness direction of the outer water gauge 2.

[0093] The limiting boss 13 can accurately position the sealing ring 3, ensuring its positional accuracy during assembly and use, thus better fulfilling its sealing function. Simultaneously, the cover 20 provides the installation and contact position for the sealing ring 3. Both the limiting boss 13 and the cover 20 press against the sealing ring 3 from both sides, ensuring its positional stability and preventing displacement or deformation under water pressure, further improving the sealing performance and stability of the water gauge structure 100.

[0094] In one embodiment, the kettle body 200 has a connecting part 202 that bends inward at the window 201 position, and the water level structure includes a sealing ring 3, which is fixed to the connecting part 202.

[0095] With this configuration, the connecting part 202 provides strong support for the sealing ring 3, further enhancing the sealing effect between the sealing ring 3 and the window 201, effectively preventing water from leaking between the window 201 and the water gauge structure 100, and ensuring the safety and reliability of the kettle.

[0096] In addition, the sealing ring 3 is located within the space enclosed by the connecting part 202, the cover part 20, the inner water gauge 1 and the limiting boss 13, so that each side of the sealing ring 3 can be well limited, further improving the structural stability of the sealing ring 3 and reducing the risk of leakage.

[0097] In one embodiment, such as Figure 7 As shown, along the thickness direction of the outer water gauge 2, the thickness h1 of the inner water gauge 1 is less than the thickness h2 of the protrusion 21.

[0098] In this way, the protrusion 21 of the outer water gauge 2 provides effective support for the inner water gauge 1, improving the overall strength of the water gauge structure 100 of the kettle. At the same time, the thinner inner water gauge 1 not only meets the food-grade requirements for contact with water, but also reduces material costs and helps to reduce the overall thickness of the water gauge structure 100, improving the simplicity and aesthetics of the kettle's appearance.

[0099] In one embodiment, such as Figure 7 As shown, along the width direction of the outer water gauge 2, the width B of the protrusion 21 is less than or equal to 6 mm. For example, the width B of the protrusion 21 can be 4 mm, 5 mm, or 6 mm.

[0100] The protrusion 21 has a relatively small width, achieving a narrow water level gauge design. The viewing window is unobstructed, ensuring the water level is visible while minimizing the impact of the water level gauge structure 100 on the appearance of the kettle body 200, thus improving the overall aesthetics and meeting user needs. Simultaneously, the narrow water level gauge structure 100 saves space on the kettle body 200, allowing more room for other functional components and optimizing the structural layout of the kettle body 200.
