Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to the field of household appliances, and more particularly to liquid heating vessels. [Background technology]

[0002] Currently, existing liquid heating containers such as health pots, electric kettles, and teapots are designed with a pot lid to prevent tipping over in order to prevent water from spilling out of the liquid heating container when it is tipped over.

[0003] As shown in FIG. 1, an existing anti-tipping pot lid 100 generally includes a pot lid lock 101 and a spring 102 for driving the pot lid lock to extend the pot lid lock to both sides.

[0004] When closing the pot lid, the user presses the spring 102 to retract the pot lid lock 101, and at the same time, pushes the pot lid downward to bring the sealing ring at the bottom end of the pot lid into contact with the sealing surface of the inner wall of the pot body, and then releases the spring 102 to extend the pot lid lock 101 from the openings on both sides of the pot lid and engage with the engaging position of the pot body. When opening the pot lid, the user presses the spring 102 again to retract the pot lid lock 101, and at the same time, pulls the pot lid upward to separate the pot lid from the pot body.

[0005] The inventors discovered that because spring 102 must be compressed when opening or closing the lid, the strength of the spring decreases over time, and after the lid has been used for a long period of time, the lid lock 101 cannot effectively and reliably lock into the engaged position on the lid body. If the lid is tipped over, the lid lock disengages from the engaged position due to the force of the impact, causing the lid to come off and spilling hot water. Therefore, when using a liquid heating container equipped with such a tip-preventing lid, there is a high risk of the user being burned. Furthermore, when closing the lid, the user must apply force to press the lid downward to seal the lid and the lid body, which is time-consuming and inconvenient to use. Summary of the Invention [Problem to be solved by the invention]

[0006] One of the objects of the present disclosure is to solve the above technical problems, that is, to provide a liquid heating container that is convenient and labor-saving to use, and is also highly safe. [Means for solving the problem]

[0007] Therefore, the present disclosure provides a liquid heating container, the liquid heating container comprising: a body having a container opening at an upper portion; and a lid assembly capable of sealingly covering the container opening. The body comprises: a body liquid outlet nozzle; a body vapor inlet disposed on an inner wall of the container opening at a position relative to the body liquid outlet nozzle; an annular body sealing surface disposed on the inner wall of the container opening and positioned below the body vapor inlet and the body liquid outlet nozzle; a first body protrusion disposed on a first side of the body liquid outlet nozzle; a second body protrusion disposed on a second side of the body liquid outlet nozzle; and a body vapor passage communicating with the body vapor inlet. The lid assembly includes a lid steam outlet, at least one lid steam inlet, a lid steam passage communicating with the lid steam outlet and the at least one lid steam inlet, a lid liquid outlet located opposite the lid steam outlet, a lid sealing ring attached to the lower end of the lid assembly, and two pairs of lid projection assemblies, each pair including a lid projection and a guide ramp, the lid projections and guide ramps spaced apart to form a receiving space therebetween. When the lid assembly is rotated, the first body projection and the second body projection enter the corresponding receiving space of the lid assembly, thereby rotating the lid assembly to fit into the container opening of the body. When the lid assembly is rotated and properly fitted into place, the lid sealing ring seals against the body sealing surface in a compressed state, the lid steam outlet is aligned with the body steam inlet, and the lid liquid outlet is aligned with the body liquid outlet nozzle.

[0008] In these embodiments, by providing two pairs of lid protrusion assemblies and first and second body protrusions as described above, the lid protrusion assemblies and the container body can be rotated and mated with each other, allowing for easy and labor-saving connection.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Exemplary embodiments are described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, like numbers in different drawings refer to the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus, systems, facilities, and methods consistent with aspects of the present invention.

[0023] A liquid heating container according to an embodiment of the present invention will be described below with reference to FIGS.

[0024] Parts A and B of FIG. 2 are schematic views of a liquid heating container according to some embodiments of the present application, from different angles. The liquid heating container includes a body 6 having a container opening at its top and a lid assembly 1 configured to sealingly cover the container opening. The body 6 includes a cavity for containing a liquid. As shown in FIG. 2, the body includes a body liquid outlet nozzle 6.04, a body steam inlet 6.2, a body sealing surface 6.03, a first body protrusion 6.01 and a second body protrusion 6.02 located on a first side and a second side of the body liquid outlet nozzle 6.04, respectively, and a body steam passage communicating with the body steam inlet 6.2. The body liquid outlet nozzle 6.04 is configured to pour liquid from the cavity of the body. The body steam inlet 6.2 is located on the inner wall of the container opening, opposite the body liquid outlet nozzle 6.04, and is configured to receive steam discharged from the lid assembly 1 and communicate with the body steam passage. It should be understood that the body steam passage may be provided in the cavity of the body 6, in the wall of the body 6, in the handle of the body 6, or in any other suitable location. The body sealing surface 6.03 is annular, installed on the inner wall of the container opening, and located below the body steam inlet 6.2 and the body liquid outlet nozzle 6.04. The body sealing surface 6.03 corresponds to the sealing ring 1.4 (FIG. 3) on the lid assembly 1, and is configured to achieve a sealing connection between the lid assembly 1 and the body 6. As shown in FIGS. 3 and 4, the lid assembly 1 includes a lid steam inlet 1.2, a lid steam inlet 1.3 (two in the illustrated embodiment, but the number may be less than two or more), a lid steam outlet 1.1, a lid steam passage (not shown) connected to the lid steam outlet 1.1, the lid steam inlet 1.2, and the lid steam inlet 1.3, a lid liquid outlet 1.075 located opposite the lid steam outlet 1.1, and a lid sealing ring 1.4 located at the lower end of the lid assembly 1. As shown in Figure 3, the lid assembly 1 also comprises two pairs of lid protrusion assemblies, each pair of which comprises lid protrusions 1.072, 1.074 and guide inclined surfaces 1.071, 1.073, the lid protrusions 1.072, 1.074 and the guide inclined surfaces 1.071, 1.073 being spaced apart from each other to form a receiving space therebetween.By rotating the lid assembly 1, the first body protrusion 6.01 and the second body protrusion 6.02 each enter into the corresponding receiving spaces of the lid assembly 1, thereby rotating the lid assembly 1 to fit into the container opening of the body 6. When the lid assembly 1 is rotated and properly fitted into place, the lid sealing ring 1.4 seals against the body sealing surface 6.03 in a compressed state, the lid steam outlet 1.1 is aligned with the body steam inlet 6.2, and the lid liquid outlet 1.075 is aligned with the body liquid outlet nozzle 6.04.

[0025] In these embodiments, the connection between the lid assembly 1 and the container body 6 can be achieved easily and labor-savingly by rotating and mating. Furthermore, the above-described structure for achieving the rotation and mating is simple and reliable, and does not suffer from functional degradation even after long-term use. Even if the liquid heating container is overturned, the lid assembly 1 will not loosen from the container body 6, ensuring safety during use of the liquid heating container and reducing the risk of users being accidentally burned. Furthermore, rotating the lid assembly 1 into place and properly mating it not only ensures a tight connection between the lid assembly 1 and the container body 6, but also ensures that steam entering the lid assembly 1 smoothly enters the container body steam inlet 6.2 and then passes through the container body steam passage to the bottom or other parts of the container, allowing the liquid in the container to smoothly flow through the lid assembly 1 to the container body liquid outlet nozzle 6.04, thereby achieving smooth pouring.

[0026] The lid sealing ring 1.4 is made of an elastomer such as silicone, and can be sealed by being compressed, while at the same time having a resilience when compressed, which further ensures that the lid assembly 1 is tightly engaged with the container body 6.

[0027] According to some embodiments of the present application, as shown in FIG. 3, the receiving space formed between the lid protrusion 1.072 or lid protrusion 1.074 and the corresponding guide ramp 1.071 or guide ramp 1.073 in each pair of lid protrusion assemblies includes an engagement space 1.0722 or engagement space 1.0742 located above the lid protrusion 1.072 or lid protrusion 1.074, and the lid protrusion 1.072 or lid protrusion 1.074 is provided with a stop surface 1.0721 or stop surface 1.0741 at the circumferential end of the engagement space 1.0722 or engagement space 1.0742. When the lid assembly 1 is rotated and fitted to the main body 6, the first main body protrusion 6.01 and the second main body protrusion 6.02 move along the corresponding guide inclined surfaces 1.071 and 1.073 in the corresponding receiving spaces, respectively, causing the lid assembly 1 to rotate horizontally and simultaneously move downward until the first main body protrusion 6.01 and the second main body protrusion 6.02 reach the corresponding engagement spaces 1.0722 and 1.0742 and abut against the corresponding stop surfaces 1.0721 and 1.0741.

[0028] When the user correctly places the lid assembly 1 on the container opening, the guide ramps 1.071 and 1.073 contact the first body projection 6.01 and the second body projection 6.02, respectively. Due to the guiding functions of the ramps and gravity, the lid assembly naturally tends to rotate clockwise, thereby guiding the user to rotate the lid assembly clockwise until the lid assembly is properly fitted into place. When the lid assembly is properly fitted into place, the first body projection 6.01 and the second body projection 6.02 reach the corresponding engagement spaces 1.0722 and 1.0742 and abut against the corresponding stop surfaces 1.0721 and 1.0741. This ensures a precise fit and secure lock between the lid assembly 1 and the container body 6.

[0029] According to some embodiments of the present application, as shown in Figure 2, the body 6 includes a first surface 6.07 located on either side of the body liquid outlet nozzle 6.04 and corresponding to the lid liquid outlet 1.075, a rotational engagement initiation surface 6.05 located around a first end of the first surface 6.07, and a rotational engagement termination surface 6.06 located around a second end of the first surface 6.07, the rotational engagement initiation surface 6.05 being located on the second side of the body liquid outlet nozzle 6.04, and the rotational engagement termination surface 6.06 being located on the first side of the body liquid outlet nozzle 6.04. According to some embodiments of the present application, as shown in Figures 11, 12, 14 and 20, the lid assembly 1 further includes an error-proof rib 1.076 protruding from a side of the lid assembly 1, which abuts against the rotational engagement termination surface 6.06 when the lid assembly 1 is rotated and properly fitted into place on the body 6.

[0030] When closing the lid, the user places the lid assembly 1 into the container opening, and the lid liquid outlet 1.075 is located on the second side of the body liquid outlet nozzle 6.04, abutting the rotational engagement start surface 6.05, with the end surface of the lid liquid outlet 1.075 facing the first surface 6.07 of the body 6. At this time, the first body projection 6.01 and the second body projection 6.02 are located in the receiving space formed between the lid projection 1.072 and the lid projection 1.074 and the guide slopes 1.071 and 1.073, respectively, and contact the corresponding guide slopes 1.071 and 1.073, while the error-proof rib 1.076 is located between the rotational engagement start surface 6.05 and the rotational engagement end surface 6.06, and does not contact the first surface 6.07. The user then rotates the lid assembly 1 clockwise until the error-proof rib 1.076 abuts the rotational engagement end surface 6.06. At this time, the lid steam outlet 1.1 is aligned with the body steam inlet 6.2, the lid liquid outlet 1.075 is aligned with the body liquid outlet nozzle 6.04, and the first body projection 6.01 and the second body projection 6.02 reach the corresponding engagement spaces 1.0722 and 1.0742 and abut against the corresponding stop surfaces 1.0721 and 1.0741, i.e., the lid assembly 1 is rotated and properly fitted into place, sealingly engaging with the body 6. The error-proof rib 1.076 prevents the user from placing and rotating the lid liquid outlet 1.075 on the wrong side when closing the lid. In fact, when the user places the lid liquid outlet 1.075 on the first side of the main body liquid outlet nozzle 6.04, the error-proof rib 1.076 interferes with the inner surface of the small diameter container opening, notifying the user that the lid assembly 1 is placed incorrectly, thereby playing an excellent role in preventing erroneous operation.

[0031] When opening the lid, the user rotates the lid assembly 1 counterclockwise until the first body protrusion 6.01 and the second body protrusion 6.02 disengage from the corresponding engagement spaces 1.0722 and 1.0742, and then lifts the lid assembly 1 upward to separate it from the main body 6.

[0032] Those skilled in the art will understand that the above structure of the lid assembly 1 and the main body 6 can be designed in the opposite direction, and when closing the lid, the lid liquid outlet 1.075 should be placed on the first side of the main body liquid outlet nozzle 6.04 and the lid assembly 1 should be rotated counterclockwise, and when opening the lid, the lid assembly 1 should be rotated clockwise.

[0033] According to some embodiments of the present application, as shown in Figures 9-13 and 18, the circumferential distance between the free end of the error-proof rib 1.076 and the side of the lid liquid outlet 1.075 away from the error-proof rib 1.076 is K1, the circumferential distance from the rotational engagement start surface 6.05 to the rotational engagement end surface 6.06 is K2, and the circumferential width of the second body projection 6.02 is K3, where K1, K2, and K3 satisfy the following relationship: K2>K1+K3, thereby ensuring sufficient rotation space for the lid assembly 1.

[0034] According to some embodiments of the present application, as shown in Figures 11 and 15-18, the radius of the circle on which the radially outer surfaces of the lid projections 1.072 and 1.074 are located is R1, the radius of the circle on which the radially outer surface of the lid liquid outlet 1.075 is located is R2, the radius of the circle on which the radially outer surface of the error-proof rib 1.076 is located is R3, the radius of the circle on which the radially inner surfaces of the first body projection 6.01 and the second body projection 6.02 are located is R4, the radius of the circle on which the root surfaces 1.077 and 1.078 of the lid projections 1.072 and 1.074 are located is R5, and the radius of the circle on which the first surface 6.07 is located is R6, where R1-R6 satisfy the following relationships: R1>R4>R5, R6>R2>R5, and R6>R3. Because R6 > R2 and R6 > R3, the lid liquid outlet 1.075 and the error-proof rib 1.076 can rotate smoothly in the space between the rotational engagement start surface 6.05 and the rotational engagement end surface 6.06 without interfering with the first surface 6.07. Because R2 > R5, the lid liquid outlet 1.075 protrudes sufficiently from the side of the lid and is close enough to the first surface 6.07, preventing a large amount of liquid from seeping into the gap between the lid assembly 1 and the container opening when pouring liquid and ensuring smooth pouring. Furthermore, because R4 > R5, the lid assembly 1 can smoothly insert into the container opening and rotate smoothly. Because R1 > R4, the lid protrusions 1.072 and 1.074 can reliably engage with the first body protrusion 6.01 and the second body protrusion 6.02. Preferably, R4 - R5 ≥ 0.5 mm and R1 - R4 ≥ 1.5 mm. When this condition is met, the lid assembly 1 can be satisfactorily fitted with the main body 6 through smooth rotation.

[0035] According to some embodiments of the present application, as shown in Figure 21, a transition slope 6.071 is provided between the first surface 6.07 corresponding to the lid liquid outlet 1.075 and the radially inner surface 6.072 of the body liquid outlet nozzle 6.04, and the radius of the circle on which the radially inner surface 6.072 of the body liquid outlet nozzle 6.04 is located is slightly smaller than the radius R6 of the circle on which the first surface 6.07 is located. This ensures a more secure engagement between the lid liquid outlet 1.075 and the first surface 6.07, while at the same time providing the user with a clear feeling that it has been rotated into place. Those skilled in the art can design the size of the radially inner surface 6.072 of the body liquid outlet nozzle 6.04 according to actual needs to ensure both an appropriate rotation force and a good connection between the lid assembly 1 and the body fluid outlet nozzle 6.04.

[0036] According to some embodiments of the present application, as shown in Figures 4 and 6, the lid assembly 1 further includes a lid sealing tube 1.8 disposed in the lid steam outlet 1.1. When the lid assembly 1 is rotated and properly fitted into the body 6, the lid sealing tube 1.8 is aligned with and sealingly engaged with the body steam inlet 6.2. This ensures that steam discharged from the lid steam outlet 1.1 enters the body steam passage through the body steam inlet 6.2 without leaking.

[0037] According to some embodiments of the present application, as shown in Figure 6, the lid assembly 1 includes an upper lid 1.01, an intermediate lid 1.07, and a lower lid 1.11, wherein the lid steam outlet 1.1 and the lid liquid outlet 1.075 are located on the side wall of the intermediate lid 1.07, the lid steam inlets 1.2 and 1.3 are located on the bottom wall of the lower lid 1.11, and the lid steam passage is located in the space between the intermediate lid 1.07 and the lower lid 1.11. According to some embodiments of the present application, as shown in Figure 5, the main body 6 includes an air conduit 4 installed therein, an upper sealing pipe 2 sealingly connected to the upper end of the air conduit 4, a lower sealing pipe 5 sealingly connected to the lower end of the air conduit 4, a steam chamber sealing lid 3 sealingly covering the upper sealing pipe 2, and a temperature controller 7 communicating with the lower sealing pipe 5 and installed on the bottom lid 9 of the main body 6, wherein the steam chamber sealing lid 3, the upper sealing pipe 2, the air conduit 4, and the lower sealing pipe 5 together form at least a part of the main body steam flow path. It should be understood that the air conduit 4 may be installed within the handle of the main body 6, or may be a channel installed on the inner wall of the main body 6 or the handle. As shown in Figures 5 and 7, the main body 6 includes a heating plate 11 arranged at its bottom for heating the liquid. The heating plate 11 is provided with a through hole 11.1, and the lower sealing tube 5 is sealingly passed through the through hole 11.1 and is sealingly connected at its upper end to the air conduit 4, thereby ensuring watertightness and stability of steam conduction.

[0038] When liquid needs to be heated, place the liquid heating container on the power supply base 10 and press the power switch 8 to start heating. When the liquid in the cavity of the main body 6 boils, steam enters the lid steam passage from the lid steam inlet 1.2 and lid steam inlet 1.3, then enters the main body steam passage from the lid steam outlet 1.1, and flows along the air guide 4 to the lower sealing tube 5. Since the lower sealing tube 5 is connected to the temperature controller 7, the steam comes into contact with the temperature controller 7, activating the temperature controller 7 and breaking the circuit. This causes the power switch 8 to pop up, and the heating of the liquid in the container is automatically stopped.

[0039] According to some embodiments of the present application, as shown in Figures 14, 22, and 23, the top surface of the upper lid 1.01 is provided with two symmetrically arranged recesses 1.013, with a gripping portion 1.011 formed between the two recesses. The gripping portion 1.011 is provided with an integrally formed lid clasp 1.02, with both ends of the lid clasp 1.02 protruding through slots at both ends of the gripping portion 1.011. Thus, when a user grips the gripping portion 1.011, the protruding ends of the lid clasp 1.02 can prevent the lid assembly 1 from slipping off. It should be understood that those skilled in the art can reasonably set the extension length of both ends of the lid clasp 1.02 according to actual needs. The length should not be too long; if it is too long, it will affect the appearance of the lid assembly and prevent the user's hand from reaching the recesses 1.013 to grasp the gripping portion 1.011. If the length is too short, the anti-slip effect will be lost. In addition, conventional lid clasps are formed by assembling two parts, one on the left and one on the right, and have an assembly gap between the two parts, making them prone to loosening and uncomfortable to the touch. According to the embodiment of the present disclosure, the lid clasp 1.02 is integrally formed from a single part, which does not feel loose when the user grips it, and has a simpler and more reliable structure.

[0040] According to some embodiments of the present application, as shown in parts C and D of FIG. 23, the lid clasp 1.02 includes an intermediate portion 1.021, wing portions 1.022 on both sides of the intermediate portion, and a flexible region 1.023 connecting the intermediate portion 1.021 and the wing portions 1.022. Due to the existence of the flexible region 1.023, the two wing portions 1.022 can be bent upward. The natural width (width when no external force is applied) of the lid clasp 1.02 is W1, the folding width of the lid clasp 1.02 is W2, the distance between the slots on both sides of the gripping portion 1.011 is W3, and the width of the gripping portion 1.011 is W4. These parameters are set such that W1>W4>W3>W2. In this way, as shown in part C of FIG. 23, before the lid clasp 1.02 is assembled to the upper lid 1.01, the wing portions 1.022 are bent upward, and the width of the lid clasp 1.02 becomes W2. Since W2<W3, both ends of the lid clasp 1.02 can smoothly enter the slots on both sides of the upper lid 1.01. After the lid clasp 1.02 is properly attached to a predetermined position, its natural width W1 is restored. Since W1>W4, both ends of the lid clasp 1.02 extend from the slots on both sides of the upper lid 1.01 to achieve an anti-slip effect. After the lid clasp 1.02 is assembled to the upper lid 1.01, the upper lid 1.01, the intermediate lid 1.07, and the lower lid 1.11 are fixed with fasteners such as screws. Due to the limiting function between the upper lid 1.01 and the lower lid 1.11, the lid clasp 1.02 can maintain a highly reliable natural width W1.
