TECHNICAL FIELD
[0001] The present application relates to the technical field of household appliances, and in particular to a liquid heating container. BACKGROUND
[0002] At present, in order to prevent water from overflowing when pouring, the existing liquid heating containers such as health-care pots, electric kettles and tea infusers are designed with anti-pouring pot lids. As shown in FIG. 1, the existing anti-pouring pot lid 100 generally comprises a pot lid lock 101 and a spring 102 driving the pot lid lock to stretch out to both sides. When closing the lid, the user needs to press the spring 102 to make the pot lid lock 101 in a retracted state, and press the lid downward at the same time, so that the sealing ring at the lower end of the lid abuts against the sealing surface on the inner wall of the pot body. Then, the spring 102 is released, and the pot lid lock 101 stretches out from the openings on both sides of the lid and is clamped into the clamping position of the pot body. When opening the lid, the user needs to press the spring 102 again to make the pot lid lock 101 in a retracted state, and then pull the lid upward, so as to realize the separation of the lid and the pot body. Figure 1
[0003] The present inventor finds that since the spring 102 needs to be compressed when opening and closing the lid, the force of the spring will decay over time, which leads to that the pot lid lock 101 cannot be reliably locked in the clamping position of the pot body after long-term use, so that the pot body may cause the pot lid lock to be detached from the clamping position under the impact force when pouring, resulting in the loosening of the lid, and further causing the hot water in the pot to overflow. Therefore, the liquid heating container comprising such an anti-pouring pot lid has a high risk of scalding the user when in use. In addition, since the user needs to press the lid downward to realize the sealing engagement of the lid and the pot body when closing the lid, it is relatively laborious and inconvenient to use. SUMMARY

DETAILED DESCRIPTION
[0048] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description herein relates to the drawings, whose reference numerals indicate corresponding or analogous elements throughout the several views. The following description of exemplary embodiments is not representative of all embodiments consistent with the present application. Rather, they are merely examples of devices, systems, apparatuses, and methods consistent with some aspects of the present application.
[0049] The following description of a liquid heating container according to some embodiments of the present application will be made with reference to the accompanying drawings. Figures 2 to 23 A liquid heating container according to some embodiments of the present application will be described.
[0050] Figure 2 A liquid heating container according to some embodiments of the present application will be described. Figure 2As shown, the body 6 also includes a body outlet 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 disposed on the first and second sides of the body outlet 6.04, and a body steam channel communicating with the body steam inlet 6.2. The body outlet 6.04 is used to pour liquid out of the cavity of the body. The body steam inlet 6.2 is disposed on the inner wall of the container opening opposite to the body outlet 6.04, used to receive steam discharged from the cap assembly 1, and communicates with the body steam channel. It should be understood that the body steam channel can be disposed within 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 and disposed on the inner wall of the container opening, located below the body steam inlet 6.2 and the body outlet 6.04, for use with the sealing ring 1.4 on the cap assembly 1. Figure 3 This, in conjunction with the main body 6, achieves a sealed connection between the cover assembly 1 and the main body 6. For example... Figure 3 , Figure 4 As shown, the cover assembly 1 includes cover steam inlets 1.2 and 1.3 (two in the illustrated exemplary embodiment, but the number may be less or more than two), cover steam outlet 1.1, a cover steam channel (not shown) communicating with the cover steam outlet 1.1 and cover steam inlets 1.2 and 1.3, a cover liquid outlet 1.075 located opposite the cover steam outlet 1.1, and a cover sealing ring 1.4 disposed at the lower end of the cover assembly 1. Furthermore, as... Figure 3 As shown, the cover assembly 1 also includes two pairs of cover protrusions. Each pair of cover protrusions includes cover protrusions 1.072 and 1.074 and guide slopes 1.071 and 1.073. The cover protrusions 1.072 and 1.074 and guide slopes 1.071 and 1.073 are spaced apart to form a receiving space between them. The cover assembly 1 can be rotated to allow the first body protrusion 6.01 and the second body protrusion 6.02 to enter the corresponding receiving spaces of the cover assembly 1 and screw into the container opening of the body 6. 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 6.04.
[0051] In these embodiments, the connection between the cover assembly 1 and the container body 6 can be achieved conveniently and labor-savingly by rotating and buckling. Moreover, the above structure for achieving the rotating and buckling is simple and reliable, and will not cause functional decay after long-term use. Even if the liquid heating container is tilted, the cover assembly 1 will not be loosened from the container body 6, which undoubtedly improves the safety of the liquid heating container in use and reduces the risk of accidental scalding of the user. In addition, when the cover assembly 1 is screwed in place, not only can the sealing connection between the cover assembly 1 and the container body 6 be ensured, but also the steam entering the cover assembly 1 can smoothly enter the body steam inlet 6.2, and then pass through the body steam channel to the bottom or other parts of the container, and the liquid in the container can also smoothly flow to the body liquid outlet 6.04 through the cover assembly 1, thereby achieving the function of smooth pouring of water.
[0052] The cover sealing ring 1.4 can be made of an elastic body such as silica gel, and can achieve sealing by compression. At the same time, compression also has a rebounding force, which further ensures the close fit of the cover assembly 1 and the container body 6.
[0053] According to some embodiments of the present application, as shown in Figure 3 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 clamping space 1.0722 or 1.0742 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 clamping space 1.0722 or 1.0742. During the process of screwing the cover assembly 1 into the body 6, the first body protrusion 6.01 and the second body protrusion 6.02 move in the corresponding receiving space along the corresponding guide slope 1.071, 1.073, so that the cover assembly 1 rotates horizontally and moves downward, until the first body protrusion 6.01 and the second body protrusion 6.02 reach the corresponding clamping space 1.0722, 1.0742 and abut against the corresponding stop surface 1.0721, 1.0741.
[0054] When the user correctly puts the cover assembly 1 into the container mouth, the guide slope 1.071, 1.073 is in contact with the first body protrusion 6.01 and the second body protrusion 6.02, respectively. Under the guidance of the slope and gravity, the cover assembly naturally has a tendency to rotate clockwise, which will guide the user to rotate the cover 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 clamping space 1.0722, 1.0742 and abut against the corresponding stop surface 1.0721, 1.0741, which ensures the accurate fit and reliable locking of the cover assembly 1 and the container body 6.
[0055] According to some embodiments of the present application, as shown inFigure 2 As shown, the body 6 further comprises a first surface 6.07 on both sides of the body liquid outlet 6.04 for cooperating with the cover liquid outlet 1.075, a screwing starting surface 6.05 located at a first end of the first surface 6.07 in the circumferential direction, and a screwing ending surface 6.06 located at a second end of the first surface 6.07 in the circumferential direction, the screwing starting surface 6.05 is located at the second side of the body liquid outlet 6.04, and the screwing ending surface 6.06 is located at the first side of the body liquid outlet 6.04. According to some embodiments of the present application, as shown in Figure 11 、 Figure 12 、 Figure 14 、 Figure 20 As shown, the cover assembly 1 further comprises a fool-proof rib 1.076 protruding from the side surface of the cover assembly 1, when the cover assembly 1 is screwed onto the body 6 in place, the fool-proof rib 1.076 abuts against the screwing ending surface 6.06.
[0056] When screwing the cover, the user places the cover assembly 1 into the container mouth, so that the cover liquid outlet 1.075 is located at the second side of the body liquid outlet 6.04 and abuts against the screwing starting surface 6.05, and the end surface of the cover liquid outlet 1.075 faces 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 located in the receiving spaces formed between the cover protrusions 1.072, 1.074 and the guide inclined surfaces 1.071, 1.073 respectively and contact the corresponding guide inclined surfaces 1.071, 1.073, and the fool-proof rib 1.076 is located between the screwing starting surface 6.05 and the screwing ending surface 6.06 and does not contact the first surface 6.07. Then, the user rotates the cover assembly 1 clockwise until the fool-proof rib 1.076 abuts against the screwing ending 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 6.04, the first body protrusion 6.01 and the second body protrusion 6.02 reach the corresponding engagement spaces 1.0722, 1.0742 and abut against the corresponding stop surfaces 1.0721, 1.0741, i.e., the cover assembly 1 is screwed into place and locked on the body 6 in a sealed manner. Due to the arrangement of the fool-proof rib 1.076, it can prevent the user from placing the cover liquid outlet 1.075 at the wrong side and rotating it when screwing the cover. In fact, if the user places the cover liquid outlet 1.075 at the first side of the body liquid outlet 6.04, the fool-proof rib 1.076 will interfere with the inner surface of the container mouth having a smaller diameter, which can remind the user that the cover assembly 1 is placed in the wrong position, and plays a good error prevention role.
[0057] When unscrewing the cover, the user only needs to rotate the cover assembly 1 in the counterclockwise direction until the first body protrusion 6.01 and the second body protrusion 6.02 are disengaged from the corresponding engagement spaces 1.0722, 1.0742, and then lifts the cover assembly 1 upward, so that the cover assembly 1 can be separated from the body 6.
[0058] It should be understood by those skilled in the art that the above structure of the cap assembly 1 and the body 6 can be designed reversely, such that when closing the cap, the cap liquid outlet 1.075 must be placed at the first side of the body liquid outlet 6.04 and the cap assembly 1 must be rotated in the counterclockwise direction, and when opening the cap, the cap assembly 1 must be rotated in the clockwise direction.
[0059] According to some embodiments of the present application, as shown in Figures 9-13 , Figure 18 the circumferential distance between the free end of the foolproof rib 1.076 and the side of the cap liquid outlet 1.075 away from the foolproof rib 1.076 is K1, the circumferential distance between the screwing start surface 6.05 and the screwing 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 cap assembly 1 has sufficient rotation space.
[0060] According to some embodiments of the present application, as shown in Figure 11 , Figures 15-18 the radius of the circle on which the radially outer side surface of the cap protrusion 1.072, 1.074 is located is R1, the radius of the circle on which the radially outer side surface of the cap liquid outlet 1.075 is located is R2, the radius of the circle on which the radially outer side surface of the foolproof rib 1.076 is located is R3, the radius of the circle on which the radially inner side surface of the first body protrusion 6.01 and the second body protrusion 6.02 is located is R4, the radius of the circle on which the root surface 1.077, 1.078 of the cap protrusion 1.072, 1.074 is located is R5, and the radius of the circle on which the first surface 6.07 is located is R6, wherein R1 to R6 satisfy the following relationships: R1 > R4 > R5, R6 > R2 > R5, and R6 > R3. Since R6 > R2 and R6 > R3, it can be ensured that the cap liquid outlet 1.075 and the foolproof rib 1.076 rotate smoothly in the space between the screwing start surface 6.05 and the screwing end surface 6.06 without interfering with the first surface 6.07. Since R2 > R5, it can be ensured that the cap liquid outlet 1.075 sufficiently protrudes from the side surface of the cap so as to be sufficiently close to the first surface 6.07, preventing a large amount of liquid from penetrating into the gap between the cap assembly 1 and the container mouth when pouring, and ensuring smooth pouring. In addition, since R4 > R5, it can be ensured that the cap assembly 1 is smoothly placed into the container mouth and rotates smoothly. Since R1 > R4, it can be ensured that the cap protrusion 1.072, 1.074 reliably engages 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 cap assembly 1 can achieve satisfactory engagement with the body 6 through smooth rotation.
[0061] According to some embodiments of the present application, as shown in Figure 21As shown, a transition slope 6.071 is provided between the first surface 6.07, which mates with the cap's outlet 1.075, and the radially inner surface 6.072 of the body's outlet 6.04. The radius of the circle containing the radially inner surface 6.072 of the body's outlet 6.04 is slightly smaller than the radius R6 of the circle containing the first surface 6.07. This better ensures the fit between the cap's outlet 1.075 and the first surface 6.07, while providing the user with a clear tactile feedback when the cap is fully rotated into place. Those skilled in the art can design the dimensions of the radially inner surface 6.072 of the body's outlet 6.04 according to actual needs, ensuring both appropriate rotational force and a good connection between the cap assembly 1 and the body's outlet 6.04.
[0062] According to some embodiments of this application, such as Figure 4 , Figure 6 As shown, the cover assembly 1 also includes a cover sealing tube 1.8 disposed at the cover steam outlet 1.1. When the cover assembly 1 is screwed into place on the body 6, the cover sealing tube 1.8 is aligned with and sealed to the body steam inlet 6.2. This ensures 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 this application, such as 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. The cover vapor outlet 1.1 and the cover liquid outlet 1.075 are located on the side wall of the middle cover 1.07, and the cover vapor inlets 1.2 and 1.3 are located on the bottom wall of the lower cover 1.11. The cover vapor channel is located in the space between the middle cover 1.07 and the lower cover 1.11. According to some embodiments of this application, such as... Figure 5 As shown, the main body 6 also includes an internal air guide pipe 4, an upper sealing pipe 2 sealed to the upper end of the air guide pipe 4, a lower sealing pipe 5 sealed to the lower end of the air guide pipe 4, a steam chamber sealing cover 3 sealingly covering the upper sealing pipe 2, and a thermostat 7 communicating with the lower sealing pipe 5 and disposed within the bottom cover 9 of the main body 6. The steam chamber sealing cover 3, the upper sealing pipe 2, the air guide pipe 4, and the lower sealing pipe 5 together form at least a portion of the steam passage of the main body. It should be understood that the air guide pipe 4 can also be disposed in the handle of the main body 6, or it can be a channel disposed on the inner wall of the main body 6 or the handle. Figure 5 and Figure 7 As shown, the main body 6 also includes a heating plate 11 for heating liquid at its bottom. The heating plate 11 is provided with a through hole 11.1. The lower sealing tube 5 passes through the through hole 11.1 in a sealed manner and its upper end is sealed to the air guide tube 4, which ensures the stability of water tightness and steam conduction.
[0064] When the 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, steam enters the cover steam passage through the cover steam inlets 1.2, 1.3, and then enters the body steam passage through the cover steam outlet 1.1, and flows along the air guide tube 4 to the lower sealing tube 5. Since the lower sealing tube 5 is in communication with the temperature controller 7, the steam contacts the temperature controller 7 and triggers the temperature controller 7, thereby achieving the disconnection of the circuit, the power switch 8 is popped up, and the heating of the liquid in the container is automatically stopped.
[0065] According to some embodiments of the present application, as shown in Figure 14 , Figure 22 , Figure 23 The upper surface of the upper cover 1.01 includes two symmetrically arranged recesses 1.013, and the portion between the two recesses constitutes a holding portion 1.011, wherein an integrally formed cover hand 1.02 is arranged in the holding portion 1.011, and the two ends of the cover hand 1.02 extend out of the slots on the two sides of the holding portion 1.011. In this way, when the user holds the holding portion 1.011, the protruding ends of the cover hand 1.02 can prevent the cover assembly 1 from falling off. It should be understood that a person skilled in the art can reasonably set the length of the two ends of the cover hand 1.02 extending out according to actual needs, which cannot be too large, otherwise it will affect the aesthetics of the cover assembly and hinder the user's hand from reaching into the recess 1.013 to grab the holding portion 1.011, and cannot be too small, otherwise it will not play a role in preventing slipping. In addition, a conventional cover hand is assembled by two parts, and since there is an assembly gap between the two parts, it is easy to loosen and feel bad. The cover hand 1.02 according to the embodiments of the present application is an integrally formed single part, and the user will not have a loose feeling when holding it, and the structure is simpler and more reliable.
[0066] According to some embodiments of the present application, as shown in Figure 23 Part C and Part D of FIG. 1, the cover hand 1.02 has a middle portion 1.021, wing portions 1.022 on both sides of the middle portion, and a flexible region 1.023 connecting the middle portion 1.021 and the wing portions 1.022. Due to the presence of the flexible region 1.023, the two wing portions 1.022 can be bent upwards. The natural width of the cover hand 1.02 (i.e. the width when not subjected to any external force) is W1, the width of the cover hand 1.02 after being bent is W2, the distance between the slots on the two sides of the holding portion 1.011 is W3, and the width of the holding portion 1.011 is W4. These parameters are set such that W1>W4>W3>W2. In this way, as shown in Figure 23As shown in part C, before the cover handle 1.02 is assembled to the upper cover 1.01, the wing 1.022 can be bent upward to make the width of the cover handle 1.02 become W2, and since W2 < W3, the two ends of the cover handle 1.02 can smoothly enter the slots on both sides of the upper cover 1.01. After the cover handle 1.02 is installed in place, its natural width W1 is restored, and since W1 > W4, the two ends of the cover handle 1.02 will protrude from the slots on both sides of the upper cover 1.01 to achieve the anti-slip effect. After the cover handle 1.02 is assembled to the upper cover 1.01, the upper cover 1.01, the middle cover 1.07 and the lower cover 1.11 are fixed together by screws or other fasteners. Under the combined limiting action of the upper cover 1.01 and the lower cover 1.11, the cover handle 1.02 maintains a reliable natural width W1.
