Description

Technical Field

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

[0002] At present, existing health pots, electric kettles, tea makers and other liquid heating containers are designed with anti-dumping lids to prevent water from overflowing when dumping. Figure 1 As shown, the existing anti-dumping pot lid 100 generally includes a pot lid lock 101 and a spring 102 that drives the pot lid lock to extend to both sides. When closing the lid, the user needs to press the spring 102 to put the pot lid lock 101 in a retracted state, and at the same time press the pot lid downward so that the sealing ring at the lower end of the pot lid abuts against the sealing surface on the inner wall of the pot body, and then release the spring 102 to make the pot lid lock 101 extend from the openings on both sides of the pot lid and snap into the snap position of the pot body. When opening the lid, the user needs to press the spring 102 again to put the pot lid lock 101 in a retracted state, and at the same time pull the pot lid upward, so as to separate the pot lid from the pot body.

[0003] The inventor of the present application has found that, since the spring 102 needs to be compressed when opening and closing the lid, the strength of the spring will decay over time, which results in that after long-term use, the lid lock 101 cannot be locked in the buckle position of the kettle body effectively and reliably, so that when the kettle body is tipped over, the lid lock may be disengaged from the buckle position under the action of impact force, causing the lid to become loose, thereby causing the hot water in the kettle to overflow. Therefore, the liquid heating container including such an anti-tipping lid has a high risk of scalding the user when in use. In addition, since the user needs to press the lid downwards to achieve the sealing engagement between the lid and the kettle body when closing the lid, it is laborious and inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0048] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices, systems, equipment and methods consistent with some aspects of the utility model.

[0049] The following will be combined Figures 2 to 23 A liquid heating container according to some embodiments of the present application is described.

[0050] Figure 2 Parts A and B of the figure schematically show from different angles a liquid heating container according to some embodiments of the present application, which includes a body 6 having a container opening at the top and a cover assembly 1 that can be sealed and covered at the container opening. The body 6 includes a cavity for containing liquid. Figure 2As shown, the body 6 also 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 respectively arranged on the first side and the second side of the body liquid outlet nozzle 6.04, and a body steam channel connected to the body steam inlet 6.2. The body liquid outlet nozzle 6.04 is used to pour liquid from the cavity of the body. The body steam inlet 6.2 is arranged on the inner wall of the container mouth at a position opposite to the body liquid outlet nozzle 6.04, for receiving steam discharged from the cover assembly 1, and communicating with the body steam channel. It should be understood that the body steam channel can be arranged 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 position. The body sealing surface 6.03 is annular and is arranged on the inner wall of the container mouth, located below the body steam inlet 6.2 and the body liquid outlet nozzle 6.04, for contacting with the sealing ring 1.4 ( Figure 3 ) to achieve a sealed connection between the cover assembly 1 and the body 6. Figure 3 , Figure 4 As shown, the cover assembly 1 includes cover steam inlets 1.2, 1.3 (two in the illustrated exemplary embodiment, but the number may be less than or more than two), a cover steam outlet 1.1, a cover steam channel (not shown) communicating with the cover steam outlet 1.1 and the cover steam inlets 1.2, 1.3, a cover liquid outlet 1.075 located at a position opposite to the cover steam outlet 1.1, and a cover sealing ring 1.4 disposed at the lower end of the cover assembly 1. In addition, as shown in FIG. Figure 3 As shown, the cover assembly 1 also includes two pairs of cover protrusion assemblies, each pair of cover protrusion assemblies includes cover protrusions 1.072, 1.074 and guide slopes 1.071, 1.073, and the cover protrusions 1.072, 1.074 and the guide slopes 1.071, 1.073 are spaced apart from each other to form a receiving space therebetween. The cover assembly 1 can be screwed into the container opening of the body 6 by rotating the first body protrusion 6.01 and the second body protrusion 6.02 into the corresponding receiving spaces of the cover assembly 1, respectively. When the cover assembly 1 is screwed into place, a compression seal is achieved between the cover sealing ring 1.4 and the body sealing surface 6.03, the cover steam outlet 1.1 is aligned with the body steam inlet 6.2, and the cover liquid outlet 1.075 is aligned with the body liquid outlet nozzle 6.04.

[0051] In these embodiments, the connection between the cover assembly 1 and the container body 6 can be conveniently and labor-savingly achieved by rotating and buckling. Moreover, the above-mentioned structure for achieving the rotating buckle is simple and reliable, and will not cause functional degradation after long-term use. Even if the liquid heating container is overturned, the cover assembly 1 will not be loosened from the container body 6, which undoubtedly improves the safety of the liquid heating container when in use and reduces the risk of accidental scalding of the user. In addition, when the cover assembly 1 is screwed into place, it can not only ensure a sealed connection between the cover assembly 1 and the container body 6, but also ensure that the steam entering the cover assembly 1 smoothly enters the body steam inlet 6.2, and then passes through the body steam channel to the bottom of the container or other parts, and can also ensure that the liquid in the container smoothly flows through the cover assembly 1 to the body liquid outlet 6.04, thereby achieving the function of smooth pouring.

[0052] The cover sealing ring 1.4 can be made of an elastomer such as silicone, and can achieve sealing by compression. At the same time, the compression also has resilience, further ensuring the tight fit between the cover assembly 1 and the container body 6.

[0053] According to some embodiments of the present application, Figure 3 As shown, the receiving space formed between the cover protrusion 1.072 or 1.074 and the corresponding guide slope 1.071 or 1.073 in each pair of cover protrusion assemblies includes a snap-fit ​​space 1.0722 or 1.0742 located above the cover protrusion 1.072 or 1.074, and the cover protrusion 1.072 or 1.074 includes a stop surface 1.0721 or 1.0741 at the circumferential end of the snap-fit ​​space 1.0722 or 1.0742. During the process of screwing the cover assembly 1 onto the body 6, the first body protrusion 6.01 and the second body protrusion 6.02 move in the corresponding receiving spaces along the corresponding guide slopes 1.071 and 1.073 respectively, so that the cover assembly 1 rotates horizontally and moves downward at the same time until the first body protrusion 6.01 and the second body protrusion 6.02 reach the corresponding engaging spaces 1.0722 and 1.0742 and abut the corresponding stop surfaces 1.0721 and 1.0741.

[0054] When the user correctly puts the cap assembly 1 into the container mouth, the guiding inclined surfaces 1.071 and 1.073 contact the first body protrusion 6.01 and the second body protrusion 6.02 respectively. Under the guidance of the inclined surfaces and gravity, the cap assembly naturally tends to rotate clockwise, which will guide the user to rotate the cap assembly clockwise until it is buckled in place. When buckled in place, the first body protrusion 6.01 and the second body protrusion 6.02 reach the corresponding engaging spaces 1.0722 and 1.0742 and abut the corresponding stop surfaces 1.0721 and 1.0741, which ensures the accurate matching and reliable locking of the cap assembly 1 and the container body 6.

[0055] According to some embodiments of the present application, Figure 2 As shown, the body 6 further includes a first surface 6.07 located on both sides of the body liquid outlet 6.04 for cooperating with the cover liquid outlet 1.075, a screw-on start surface 6.05 located at a first end of the first surface 6.07 in the circumferential direction, and a screw-on end surface 6.06 located at a second end of the first surface 6.07 in the circumferential direction, the screw-on start surface 6.05 is located at a second side of the body liquid outlet 6.04, and the screw-on end surface 6.06 is located at a first side of the body liquid outlet 6.04. According to some embodiments of the present application, as Fig.11 , Fig.12 , Fig.14 , Fig. 20 As shown, the cover assembly 1 further includes an anti-foolproof bone 1.076 protruding from the side surface of the cover assembly 1. When the cover assembly 1 is screwed into place on the body 6, the anti-foolproof bone 1.076 abuts against the screw-on end surface 6.06.

[0056] When closing the lid, the user places the lid assembly 1 in the container mouth, so that the lid outlet 1.075 is located at the second side of the body liquid outlet nozzle 6.04 and abuts against the screw-on start surface 6.05, and the end surface of the lid outlet 1.075 is facing the first surface 6.07 of the body 6. At this time, the first body protrusion 6.01 and the second body protrusion 6.02 are just located in the receiving space formed between the lid protrusions 1.072, 1.074 and the guide slopes 1.071, 1.073 and contact the corresponding guide slopes 1.071, 1.073, and the anti-fool bone 1.076 is located between the screw-on start surface 6.05 and the screw-on end surface 6.06 and does not contact the first surface 6.07. Then, the user rotates the lid assembly 1 clockwise until the anti-fool bone 1.076 abuts against the screw-on end surface 6.06. At this time, the cover steam outlet 1.1 is aligned with the body steam inlet 6.2, the cover liquid outlet 1.075 is aligned with the body liquid outlet nozzle 6.04, the first body protrusion 6.01 and the second body protrusion 6.02 reach the corresponding engaging spaces 1.0722, 1.0742 and abut the corresponding stop surfaces 1.0721, 1.0741, that is, the cover assembly 1 is screwed into place and sealedly locked on the body 6. Due to the provision of the anti-fool bone 1.076, it can prevent the user from placing the cover liquid outlet 1.075 on the wrong side and rotating it when closing the cover. In fact, if the user places the cover liquid outlet 1.075 on the first side of the body liquid outlet nozzle 6.04, the anti-fool bone 1.076 will interfere with the inner surface of the container mouth with a smaller diameter, which can remind the user that the cover assembly 1 is misplaced, playing a good anti-mistake role.

[0057] When opening the cover, the user only needs to rotate the cover assembly 1 in a counterclockwise direction until the first body protrusion 6.01 and the second body protrusion 6.02 are disengaged from the corresponding engaging spaces 1.0722 and 1.0742, and then lift the cover assembly 1 upward to separate the cover assembly 1 from the body 6.

[0058] Those skilled in the art should understand that the above-mentioned structure of the cover assembly 1 and the main body 6 can be designed in the opposite direction, so that when closing the cover, the cover liquid outlet 1.075 must be placed on the first side of the main body liquid outlet nozzle 6.04 and the cover assembly 1 must be rotated in the counterclockwise direction, and when opening the cover, the cover assembly 1 must be rotated in the clockwise direction.

[0059] According to some embodiments of the present application, Figure 9-13 , Fig.18 As shown, the circumferential distance between the free end of the anti-fool bone 1.076 and the side of the cover liquid outlet 1.075 away from the anti-fool bone 1.076 is K1, the circumferential distance from the screw-on start surface 6.05 to the screw-on end surface 6.06 is K2, and the circumferential width of the second body protrusion 6.02 is K3, wherein K1, K2, and K3 satisfy the following relationship: K2>K1+K3. In this way, it can be ensured that the cover assembly 1 has sufficient rotation space.

[0060] According to some embodiments of the present application, Fig.11 , Figure 15-18 As shown, the radius of the circle where the radial outer side surfaces of the cover protrusions 1.072 and 1.074 lie is R1, the radius of the circle where the radial outer side surfaces of the cover liquid outlet 1.075 lie is R2, the radius of the circle where the radial outer side surfaces of the anti-fouling bone 1.076 lie is R3, the radius of the circle where the radial inner side surfaces of the first body protrusion 6.01 and the second body protrusion 6.02 lie is R4, the radius of the circle where the root surfaces 1.077 and 1.078 of the cover protrusions 1.072 and 1.074 lie is R5, and the radius of the circle where the first surface 6.07 lies is R6, wherein R1 to R6 satisfy the following relationship: R1>R4>R5, R6>R2>R5, and R6>R3. Since R6>R2 and R6>R3, it can be ensured that the cover liquid outlet 1.075 and the anti-fool bone 1.076 can rotate smoothly in the space between the screw-on starting surface 6.05 and the screw-on ending surface 6.06 without interfering with the first surface 6.07. Since R2>R5, it can be ensured that the cover liquid outlet 1.075 protrudes sufficiently from the side surface of the cover, so that it is close enough to the first surface 6.07, preventing a large amount of liquid from penetrating into the gap between the cover assembly 1 and the container mouth when pouring liquid, ensuring smooth liquid discharge. In addition, since R4>R5, it can be ensured that the cover assembly 1 can be smoothly placed in the container mouth and rotated smoothly. Since R1>R4, it can be ensured that the cover protrusions 1.072, 1.074 are reliably buckled with the first body protrusion 6.01 and the second body protrusion 6.02. Preferably, R4-R5>=0.5mm, and R1-R4>=1.5mm. When this condition is met, the cover assembly 1 can achieve satisfactory snap-fitting with the body 6 through smooth rotation.

[0061] According to some embodiments of the present application, Fig.21As shown, a transition slope 6.071 is provided between the first surface 6.07 for cooperating with the cover liquid outlet 1.075 and the radial inner surface 6.072 of the main body liquid outlet nozzle 6.04, and the radius of the circle where the radial inner surface 6.072 of the main body liquid outlet nozzle 6.04 is located is slightly smaller than the radius R6 of the circle where the first surface 6.07 is located. In this way, the cooperation between the cover liquid outlet 1.075 and the first surface 6.07 can be better ensured, while giving the user a clear feeling of rotation in place. Those skilled in the art can design the size of the radial inner surface 6.072 of the main body liquid outlet nozzle 6.04 according to actual needs, so as to ensure that the rotation force is appropriate and the cover assembly 1 and the main body liquid outlet nozzle 6.04 are well connected.

[0062] According to some embodiments of the present application, Figure 4 , Figure 6 As shown, the cover assembly 1 further comprises a cover sealing tube 1.8 arranged at the cover steam outlet 1.1, and when the cover assembly 1 is screwed into place on the body 6, the cover sealing tube 1.8 is aligned with the body steam inlet 6.2 and sealed. In this way, it can be ensured that the steam discharged from the cover steam outlet 1.1 enters the body steam channel through the body steam inlet 6.2 without leakage.

[0063] According to some embodiments of the present application, Figure 6 As shown, the cover assembly 1 includes an upper cover 1.01, a middle cover 1.07 and a lower cover 1.11, wherein the cover steam outlet 1.1 and the cover liquid outlet 1.075 are located on the side wall of the middle cover 1.07, the cover steam inlets 1.2 and 1.3 are located on the bottom wall of the lower cover 1.11, and the cover steam channel is located in the space between the middle cover 1.07 and the lower cover 1.11. According to some embodiments of the present application, as Figure 5 As shown, the body 6 also includes an air duct 4 disposed inside it, an upper sealing tube 2 sealedly connected to the upper end of the air duct 4, a lower sealing tube 5 sealedly connected to the lower end of the air duct 4, a steam chamber sealing cover 3 sealingly covered on the upper sealing tube 2, and a temperature controller 7 connected to the lower sealing tube 5 and disposed in the bottom cover 9 of the body 6. The steam chamber sealing cover 3, the upper sealing tube 2, the air duct 4 and the lower sealing tube 5 together form at least a part of the steam channel of the body. It should be understood that the air duct 4 can also be disposed in the handle of the body 6, or can be a channel disposed on the inner wall of the body 6 or the handle. Figure 5 and Figure 7 As shown, the body 6 also includes a heating plate 11 arranged at the bottom thereof for heating the liquid. The heating plate 11 is provided with a conducting hole 11.1. The lower sealing tube 5 seals through the conducting hole 11.1 and is sealedly connected to the air duct 4 at the upper end, thereby ensuring water tightness and stability of steam conduction.

[0064] When liquid needs to be heated, the liquid heating container is placed on the power base 10, and the power switch 8 is pressed to start heating. When the liquid in the cavity of the body 6 boils, the steam will enter the cover steam channel through the cover steam inlets 1.2 and 1.3, and then enter the body steam channel through the cover steam outlet 1.1, and flow along the air guide pipe 4 to the lower sealing tube 5. Since the lower sealing tube 5 is connected to the thermostat 7, the steam will contact the thermostat 7 and trigger the thermostat 7, thereby disconnecting the circuit, and the power switch 8 pops up, automatically stopping the heating of the liquid in the container.

[0065] According to some embodiments of the present application, Fig.14 , Fig. 22 , Fig.23 As shown, the upper surface of the upper cover 1.01 includes two symmetrically arranged depressions 1.013, and the portion between the two depressions constitutes a grip portion 1.011, wherein an integrally formed cover buckle 1.02 is provided in the grip portion 1.011, and the two ends of the cover buckle 1.02 extend from the slots on both sides of the grip portion 1.011. In this way, when the user holds the grip portion 1.011, the protruding ends of the cover buckle 1.02 can prevent the cover assembly 1 from slipping. It should be understood that those skilled in the art can reasonably set the length of the two ends of the cover buckle 1.02 according to actual needs. The length should not be too large, otherwise it will affect the appearance of the cover assembly and prevent the user's hand from reaching into the depression 1.013 to grasp the grip portion 1.011, and it should not be too small, otherwise it will not play an anti-slip role. In addition, the conventional cover buckle is formed by assembling two left and right parts together. Since there is an assembly gap between the two parts, it is easy to be loose and have a bad hand feel. According to the embodiment of the present application, the cover buckle handle 1.02 is a single component formed in one piece, and the user will not feel loose when holding it, and the structure is simpler and more reliable.

[0066] According to some embodiments of the present application, Fig.23 As shown in parts C and D of , the cover buckle 1.02 has a middle portion 1.021, wing portions 1.022 located on both sides of the middle portion, and a flexible area 1.023 connecting the middle portion 1.021 and the wing portions 1.022. Due to the existence of the flexible area 1.023, the two wings 1.022 can be bent upward. The natural width of the cover buckle 1.02 (i.e., the width when not subject to any external force) is W1, the width of the cover buckle 1.02 after bending 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 so that W1>W4>W3>W2. In this way, as Fig.23As shown in part C, before assembling the lid buckle handle 1.02 to the upper lid 1.01, the wing part 1.022 can be bent upward so that the width of the lid buckle handle 1.02 becomes W2. Since W2 < W3, both ends of the lid buckle handle 1.02 can smoothly enter the slot seams on both sides of the upper lid 1.01. After the lid buckle handle 1.02 is installed in place, it returns to its natural width W1. Since W1 > W4, both ends of the lid buckle handle 1.02 will protrude from the slot seams on both sides of the upper lid 1.01, achieving an anti-slip effect. After the lid buckle handle 1.02 is assembled on the upper lid 1.01, the upper lid 1.01, the middle lid 1.07, and the lower lid 1.11 are fixed together by fasteners such as screws. Under the combined limiting effect of the upper lid 1.01 and the lower lid 1.11, the lid buckle handle 1.02 maintains a reliable natural width W1.
