Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a liquid heating container. Background Art

[0002] A liquid heating container includes a container body and an outer cover that is fastened to the container body. The container body is provided with an exhaust hole. When the container heats liquid, steam generated inside the container can be discharged from the exhaust hole through the gap between the container body and the outer cover. To improve the stability of the outer cover, a retaining ring can be provided on the container body. The retaining ring can abut against the side wall of the outer cover to provide support for the outer cover. However, this will result in the gap between the container body and the outer cover being blocked from the outside world, resulting in poor steam discharge. This can lead to excessive pressure between the container body and the outer cover, creating a safety hazard. Utility Model Content

[0003] The present application provides a liquid heating container, which can solve the problem in the prior art that steam cannot be discharged smoothly when the liquid heating container is heated.

[0004] The present application provides a liquid heating container, comprising: a kettle body, having an exhaust hole; a limiting ring, installed on the kettle body, the limiting ring having a support surface; an outer cover, buckled onto the kettle body, the side wall of the outer cover having a first support mating surface, the first support mating surface abutting and mating with the support surface; at least one of the support surface and the first support mating surface is provided with a pressure relief groove, and the pressure relief groove is respectively connected to the exhaust hole and the outside world.

[0005] In the above scheme, the limiting ring is used to support the outer cover when it is fastened to the body of the kettle, so as to improve the stability of the outer cover when it is fastened to the body of the kettle. When the liquid heating container heats the liquid, the high-temperature steam in the kettle body can flow to the outside along the exhaust hole, the gap between the kettle body and the outer cover, and the pressure relief groove. That is, the pressure relief groove can play the role of exhausting and relieving pressure, preventing the gas pressure between the kettle body and the outer cover from being too high and causing the outer cover to be lifted off, reducing the safety hazards during the use of the liquid heating container, and improving the user experience. Moreover, when the liquid heating container stops heating, the gas in the kettle body contracts due to the drop in temperature, causing the gas between the outer cover and the kettle body to be sucked back into the body through the exhaust hole. At this time, the outside air can enter between the outer cover and the kettle body through the pressure relief groove, reducing the risk of vacuum forming between the kettle body and the outer cover, which makes it impossible to remove the outer cover, and improving the user experience.

[0006] In a possible design, the number of the pressure relief grooves is at least two.

[0007] In the above solution, when one pressure relief groove fails, the remaining pressure relief grooves can still function normally to relieve pressure, exhaust air or intake air, thereby helping to improve the reliability of the pressure relief grooves.

[0008] In a possible design, the support surface is provided with two pressure relief grooves; the two pressure relief grooves are distributed relatively along the radial direction of the limiting ring.

[0009] In the above scheme, the two pressure relief grooves are relatively distributed along the radial direction of the limiting ring, which can achieve uniform pressure relief and exhaust and uniform air intake, so as to improve the pressure relief efficiency and air intake efficiency of the liquid heating container.

[0010] In a possible design, the kettle body includes a main body, and the main body is provided with a convex rib; the inner wall of the limiting ring is provided with a limiting groove, and the limiting groove is interference fit with the convex rib.

[0011] In the above solution, the limiting groove and the convex rib are interference fit, which limits the axial movement of the limiting ring along the kettle body, thereby achieving a fixed connection between the limiting ring and the body.

[0012] In a possible design, the liquid heating container further includes a handle, and the handle is fixedly connected to the limiting ring.

[0013] In the above solution, the user can take or move the liquid heating container by the handle, which is more convenient to use.

[0014] In a possible design, an outer wall of the limiting ring is provided with a mounting groove, and at least a portion of the handle is located in the mounting groove.

[0015] In the above solution, the mounting groove can limit the axial movement of the handle along the kettle body, and can also limit the radial movement of the handle along the kettle body, thereby helping to improve the installation stability of the handle.

[0016] In a possible design, the kettle body includes a main body and an inner cover detachably connected to the main body, the exhaust hole is located on the inner cover; and the outer cover is buckled onto the inner cover.

[0017] In the above solution, when the liquid heating container is heating liquid, the inner lid snaps onto the main body, preventing the boiling liquid from splashing out, thereby avoiding burns to the user. Steam generated by the heated liquid can be discharged outward through the vent, thereby preventing excessive pressure inside the kettle. After heating, when the user needs to drink water, the inner lid can be removed from the main body and the water can be poured out. The detachable structure makes it easier for the user to clean the main body and inner lid.

[0018] In one possible design, the inner cover includes a cover body and a connecting piece that are fixedly connected, and at least a portion of the connecting piece extends into the body to be detachably connected to the body; the cover body is buckled into the body, and the side wall of the cover body has a second supporting mating surface, and the second supporting mating surface is abutted against the supporting surface.

[0019] In the above solution, the second support mating surface abuts against the support surface. On the one hand, the limiting ring can provide support to the cover body, thereby improving the stability of the inner cover. On the other hand, the user can judge whether the connector is installed in place by observing whether the second support mating surface abuts against the support surface, thereby improving the convenience of user use.

[0020] In a possible design, a breathable and waterproof membrane is installed on the connecting member, and the steam in the body can flow to the exhaust hole through the breathable and waterproof membrane.

[0021] In the above solution, the breathable waterproof membrane is breathable and can allow steam to pass through, thereby realizing the pressure relief and exhaust function. At the same time, the breathable waterproof membrane is also waterproof, preventing the liquid in the body from passing through, thereby avoiding water leakage in the liquid heating container.

[0022] In a possible design, the outer cover is provided with a first magnetic component, and the inner cover is provided with a second magnetic component; the outer cover and the inner cover are magnetically connected via the first magnetic component and the second magnetic component.

[0023] In the above solution, when the outer cover is buckled onto the kettle body, the outer cover and the inner cover can be magnetically connected via the first magnetic part and the second magnetic part, thereby improving the stability of the outer cover when buckled onto the kettle body.

[0024] It should be understood that the foregoing general description and the following detailed description are merely illustrative and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0057] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0059] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0060] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0061] The embodiment of the present application provides a liquid heating container, such as Figure 1 As shown, the liquid heating container includes a kettle body 1 and an outer cover 3 that is buckled into the kettle body 1. The kettle body 1 includes a main body 11, which includes a fixedly connected outer shell 11a and a base 11b. The outer shell 11a is provided with an inner liner 11c for holding liquid and a heating plate assembly 11d installed on the outer bottom wall of the inner liner 11c and used to heat the liquid. The base 11b is provided with a circuit board assembly 11e. The circuit board assembly 11e is electrically connected to the heating plate assembly 11d for controlling the heating temperature or heating time of the liquid heating container. The kettle body 1 also includes an inner cover 12 that is detachably connected to the main body 11, combined with Figure 2 As shown, the top of the inner cover 12 is provided with a vent hole 10. When the liquid heating container is heating liquid, the inner cover 12 is snap-fitted onto the body 11 to prevent the boiling liquid from splashing outwards, thereby avoiding scalding the user. The steam generated by the heated liquid can be discharged outwards through the vent hole 10, thereby preventing excessive pressure inside the kettle body 1. After heating is completed, when the user needs to drink water, the inner cover 12 can be removed from the body 11 and the water can be poured out. The detachable structure makes it easier for the user to clean the body 11 and inner cover 12.

[0062] The outer cover 3 is inverted on the outside of the inner cover 12 to prevent dust. There is a gap between the inner wall of the outer cover 3 and the outer wall of the inner cover 12. When the liquid heating container heats the liquid, the steam at the exhaust hole 10 can flow to the gap, that is, the outer cover 3 can guide the steam, and the temperature of the outer cover 3 is relatively low, which can condense part of the steam and reduce the risk of high-temperature steam scalding the user. After the heating is completed, when the user needs to drink water, the outer cover 3 can be removed and used as a drinking cup, which improves the practicality of the liquid heating container. Figure 3 As shown, a limiting ring 2 is also mounted on the body 11. The limiting ring 2 has a support surface 21, which is the surface of the limiting ring 2 facing the outer cover 3 along the axial direction Z of the kettle body 1. The side wall of the outer cover 3 has a first supporting mating surface 31, which is the surface of the side wall of the outer cover 3 facing the limiting ring 2 along the axial direction Z of the kettle body 1. The first supporting mating surface 31 can abut and mate with the supporting surface 21. That is, the limiting ring 2 is used to support the outer cover 3 when it is buckled onto the kettle body 1, thereby improving the stability of the outer cover 3 when buckled onto the kettle body 1.

[0063] Specifically, at least one of the support surface 21 and the first support mating surface 31 is provided with a pressure relief groove 4. Along the radial direction Z of the kettle body 1, one end of the pressure relief groove 4 is connected to the exhaust hole 10 through the gap between the outer cover 3 and the inner cover 12, and the other end is connected to the outside. Figure 3 As shown in the direction of the middle arrow, when the liquid heating container heats the liquid, the high-temperature steam in the kettle body 1 can flow to the outside along the vent 10, the gap between the outer cover 3 and the inner cover 12, and the pressure relief groove 4. That is, the pressure relief groove 4 can play the role of exhausting and relieving pressure, preventing the gas pressure between the kettle body 1 and the outer cover 3 from being too high and causing the outer cover 3 to be lifted off, reducing the safety hazards during the use of the liquid heating container, and improving the user's experience. Moreover, when the liquid heating container stops heating, the gas in the kettle body 1 contracts due to the drop in temperature, causing the gas between the outer cover 3 and the kettle body 1 to be sucked back into the main body 11 through the vent 10. At this time, the outside air can enter between the outer cover 3 and the kettle body 1 through the pressure relief groove 4, reducing the risk of vacuum forming between the kettle body 1 and the outer cover 3 and causing the outer cover 3 to be unable to be removed, thereby improving the user's experience.

[0064] This embodiment is described by taking the pressure relief groove 4 provided on the support surface 21 as an example. Figure 4 As shown, the number of pressure relief grooves 4 should be set to at least two, so that when one pressure relief groove 4 fails, the remaining pressure relief grooves 4 can still function normally to relieve pressure, exhaust or intake air, thereby improving the reliability of the pressure relief grooves 4. The number of pressure relief grooves 4 can be designed to be 2, 3, 4, 5 or more according to the ventilation requirements of the liquid heating container, and this embodiment does not impose any limitation on this.

[0065] When the number of pressure relief grooves 4 is two, the two pressure relief grooves 4 can be oppositely distributed along the radial direction X of the limiting ring 2, so as to realize uniform pressure relief and uniform air intake, thereby improving the pressure relief efficiency and air intake efficiency of the liquid heating container. If the distance between the two pressure relief grooves 4 is very close, when the liquid heating container heats the liquid, a part of the steam needs to pass through a relatively long path to be discharged to the outside through the pressure relief grooves 4, which results in low pressure relief efficiency of the liquid heating container and potential safety hazards. Correspondingly, when the number of pressure relief grooves 4 is greater than two, the plurality of pressure relief grooves 4 can be uniformly and spacedly distributed along the circumferential direction of the limiting ring 2, so as to realize uniform pressure relief and uniform air intake, thereby improving the pressure relief efficiency and air intake efficiency of the liquid heating container.

[0066] In a specific embodiment, as shown in Figure 2 and Figure 3 , the body 11 is provided with a protruding rib 111 which protrudes outwardly along the radial direction X of the kettle body 1. Correspondingly, as shown in Figure 3 and Figure 4 , the inner wall of the limiting ring 2 is provided with a limiting groove 22 which is recessed inwardly along the radial direction X of the kettle body 1. When the limiting ring 2 is installed on the body 11, the protruding rib 111 can extend into the limiting groove 22 and be clamped and matched with the limiting groove 22, so as to limit the movement of the limiting ring 2 along the axial direction Z of the kettle body 1 and improve the installation stability of the limiting ring 2. Further, the limiting groove 22 can be interference-fitted with the protruding rib 111, so as to realize the fixed connection between the limiting ring 2 and the body 11.

[0067] The material of the limiting ring 2 can be hard plastic, which has low cost and is convenient to install.

[0068] In a specific embodiment, as shown in Figure 1 and Figure 2 , the liquid heating container further comprises a handle 5 which is fixedly connected with the limiting ring 2. The user can take or move the liquid heating container through the handle 5, which is more convenient to use. Specifically, the handle 5 can be welded with the limiting ring 2, or the handle 5 can be fixedly connected with the handle 5 through a fastener. As shown in Figure 4 , when the handle 5 is fixedly connected with the limiting ring 2 through a fastener, an installation groove 23 can be arranged on the outer wall of the limiting ring 2, so that at least part of the handle 5 is located in the installation groove 23. The installation groove 23 can limit the movement of the handle 5 along the axial direction Z of the kettle body 1, and also limit the movement of the handle 5 along the radial direction X of the kettle body 1, thereby facilitating the improvement of the installation stability of the handle 5.

[0069] In a specific embodiment, as shown in Figure 3As shown, the inner cover 12 includes a fixedly connected cover body 121 and a connector 122, at least part of which extends into the body 11 and is detachably connected to the body 11. Specifically, the connector 122 can be snap-fitted or threadedly fitted with the inner wall of the body 11. The cover body 121 is snapped onto the outer side of the body 11, and the side wall of the cover body 121 has a second support fitting surface 121a, which is in abutment with the support surface 21. On the one hand, the limiting ring 2 can provide support for the cover body 121, thereby improving the stability of the inner cover 12. On the other hand, the user can judge whether the connector 122 is installed in place by observing whether the second support fitting surface 121a is in abutment with the support surface 21, thereby improving the convenience of user use.

[0070] A sealing ring 125 is further provided between the cover 121 and the body 11 to prevent liquid or steam in the body 11 from flowing out from between the cover 121 and the body 11 , thereby improving the sealing performance of the kettle body 1 .

[0071] like Figure 3 As shown, the exhaust hole 10 is provided at the top of the cover 121, and the inner cover 12 further includes a filter screen 126 with air holes. The filter screen 126 is installed at the lower end of the connecting member 122, which is also provided with air holes. The connecting member 122 is also installed with a breathable waterproof membrane 123. The steam in the body 11 can flow to the exhaust hole 10 through the filter screen 126, the breathable waterproof membrane 123 and the connecting member 122. Among them, the breathable waterproof membrane 123 is breathable and can allow steam to pass through, realizing the pressure relief and exhaust function. At the same time, the breathable waterproof membrane 123 is also waterproof and can prevent the liquid in the body 11 from passing through, thereby preventing water leakage in the liquid heating container.

[0072] In a specific embodiment, a first magnetic member 32 is provided on the outer cover 3, and a second magnetic member 124 is provided on the cover body 121 of the inner cover 12. When the outer cover 3 is buckled onto the kettle body 1, the outer cover 3 and the inner cover 12 can be magnetically connected via the first magnetic member 32 and the second magnetic member 124, thereby improving the stability of the outer cover 3 when buckled onto the kettle body 1 and preventing the outer cover 3 from falling off.

[0073] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
