Description

Technical Field

[0001] The utility model relates to the technical field of liquid heaters, in particular to a liquid heater. Background Art

[0002] In modern kitchen life, liquid heaters are increasingly used. During the use of liquid heaters, foam is prone to overflow when making drinks.

[0003] In order to solve the problem of overflow during stewing in a health-preserving kettle, the prior art CN201721213292.2 proposes that an anti-overflow electrode is provided on the outer shell on the upper side of the inner liner of the health-preserving kettle. When the foam contacts the anti-overflow electrode, the anti-overflow electrode is turned on, and the control board connected to the anti-overflow electrode cuts off the power supply of the heating device or reduces the heating power of the heating device, thereby preventing the foam from overflowing. However, the anti-overflow electrode of the prior art is installed on the outer shell, and the outer shell and the anti-overflow electrode cannot be disassembled, making the prior art difficult to clean.

[0004] Some existing technologies, such as CN201820211183.5, propose to provide an anti-overflow electrode at the connection between the handle and the upper end of the inner pot, and the anti-overflow electrode extends into the boiling space of the inner pot to detect whether the foam overflows. Although this solution does not require the outer shell to be higher than the inner pot, the anti-overflow electrode of this solution cannot be removed, which makes it difficult for the user to put his hand into the boiling space of the inner pot during the cleaning process, making it difficult to clean, and the anti-overflow electrode is easily damaged during the cleaning process.

[0005] In order to solve the technical problem that the anti-overflow electrode is difficult to remove, the prior art has a technical solution of installing the anti-overflow electrode on the pot lid. For example, in the prior art CN201811617937.8, the anti-overflow electrode is arranged on the lower side of the pot lid, and the anti-overflow electrode extends into the boiling space of the inner pot; the anti-overflow electrode is connected to the metal part of the inner pot through the conductive touch rod on the pot lid. The pot lid is provided with a conductive touch rod, which slides in the pot lid; the pot lid is also provided with an elastic member, which pushes the conductive touch rod and can extend out of the pot lid. When the pot lid is closed on the inner pot, the elastic member pushes the conductive touch rod to abut against the metal part of the inner pot, and the conductive touch rod is electrically connected to the anti-overflow electrode through the elastic member.

[0006] During use of the prior art, the elastic member is used to electrically connect the anti-overflow electrode and the conductive contact rod, and the elastic member also ensures that the conductive contact rod abuts against the metal part of the inner container, so the elastic force of the elastic member cannot be too small to ensure that the electrical connection between the anti-overflow electrode, the conductive contact rod and the inner container is stable. However, the lid and the inner container are installed and sealed by a seal, and the elastic member will squeeze the seal to deform the seal and offset the lid, which will cause the conductive contact rod to fail to completely abut against the inner container.

[0007] In particular, in order to facilitate the closing of the lid and the kettle body and the convenience of taking out, the prior art also provides a sealing tongue on the outside of the sealing ring. For example, the prior art CN201820507586.4 includes a sealing ring provided at the joint between the upper port of the cup body and the side wall of the cup cover, and the sealing ring includes an annular sealing body and a sealing lip arranged outside the sealing body. When the cup lid is closed, the sealing lip abuts against the upper port of the cup body. The sealing tongue is relatively soft, which is convenient for abutting against the cup body and for the user to take out the lid. However, in the scenario where the elastic member connects the lid and the kettle body, the sealing tongue will increase the displacement of the lid, and the elastic member cannot make the conductive touch rod completely abut against the inner liner. Utility Model Content

[0008] The utility model aims to provide a liquid heater, which is used to solve the technical problem that when a sealing tongue is provided on a sealing ring of a kettle lid, the elastic component squeezes the kettle lid to cause it to deviate, and the sealing tongue cannot support the kettle lid to press the elastic component.

[0009] An embodiment of the present application provides a liquid heater, comprising a kettle body with a kettle mouth and a kettle cover arranged above the kettle body, when the kettle cover is closed with the kettle body, the kettle cover and the kettle body are abutted by an elastic component, comprising a sealing ring, the sealing ring comprising a sealing body and a sealing tongue, the sealing body is sleeved on the outer side surface of the kettle cover, the sealing tongue extends from both sides of the elastic component along the outer peripheral side of the sealing body away from the elastic component, the sealing tongue abuts against the inner side surface of the kettle mouth, and the deformation amount of the sealing tongue on each side tends to decrease from the elastic component to the position away from the elastic component.

[0010] In some embodiments of the present invention, at least three supporting ribs are radially arranged between the sealing tongue and the sealing body on each side, and the strength of the supporting rib on each side increases from the elastic component to a position away from the elastic component.

[0011] In some embodiments of the present invention, the strength of the support ribs on each side increases gradually from the elastic component to a position away from the elastic component until the strength of the support ribs no longer increases.

[0012] In some embodiments of the present invention, the cross-section of the supporting ribs on each side increases gradually from the elastic component to a position away from the elastic component.

[0013] In some embodiments of the present invention, the spacing between the supporting ribs on each side gradually decreases from the elastic component to a location away from the elastic component.

[0014] In some embodiments of the present invention, the supporting ribs on each side are symmetrically arranged on both sides of the elastic component.

[0015] In some embodiments of the present invention, the length of the supporting rib is not greater than the length of the sealing ring.

[0016] In some embodiments of the present invention, the thickness of the sealing tongue on each side gradually increases from the elastic component to a position away from the elastic component.

[0017] In some embodiments of the present utility model, a longitudinal section of the sealing tongue bends and extends upward from inside to outside, and the sealing tongue and the sealing ring together form an upward opening.

[0018] In some embodiments of the present invention, the width of the sealing tongue is not less than 10 mm.

[0019] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0020] When the pot lid is closed over the pot mouth, the sealing tongue abuts against the inner side of the pot mouth, so that the elastic component abuts against the pot lid or the pot mouth, and at the same time the elastic component squeezes the pot lid and the sealing tongue toward the side away from the elastic component. Therefore, the deformation of the sealing tongue on each side of the present embodiment tends to decrease, thereby reducing the movement of the pot lid and allowing the sealing tongue to continue to squeeze the elastic component.

[0021] In some embodiments, support ribs are arranged between the sealing tongue and the sealing body on each side, so that the support ribs can provide support for the sealing tongue. The greater the strength of the support ribs, the smaller the deformation of the sealing tongue at that location. In order to reduce the deformation of the sealing tongue away from the elastic component and to compress the elastic component, the strength of the support ribs gradually increases from the elastic component to the location away from the elastic component.

[0022] In some embodiments, the thickness of the sealing tongue on each side gradually increases from the elastic component to the position away from the elastic component. The thickness of the sealing tongue increases the bending resistance of the sealing tongue, so that the deformation of the sealing tongue on each side tends to decrease from the elastic component to the position away from the elastic component, thereby facilitating the compression of the elastic component.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 3 As shown, the liquid heater comprises a pot body with a pot mouth and a pot cover 5 covering the pot mouth, and the pot cover 5 or the pot mouth may be provided with an elastic component 4, and when the pot cover 5 covers the pot mouth, the elastic component 4 may abut against the pot cover 5 and the pot mouth, so that the pot cover 5 and the pot mouth are electrically connected through the elastic component 4. The elastic component 4 may be an elastic ejector pin.

[0029] The liquid heater further comprises a sealing ring, which comprises a sealing body 1 sleeved on the outer side of the pot cover 5, and a sealing tongue 2, which extends from both sides of the elastic component 4 along the outer circumference of the sealing body 1 and away from the elastic component 4. When the pot cover 5 is closed with the pot mouth, the sealing tongue 2 abuts against the inner side of the pot mouth, so that the elastic component 4 abuts against the pot cover 5 or the pot mouth, and at the same time, the elastic component 4 presses the pot cover 5 and the sealing tongue 2 toward the side away from the elastic component 4, so that the deformation amount of the sealing tongue 2 on each side of the embodiment tends to decrease, thereby reducing the movement amount of the pot cover 5, and also allowing the sealing tongue 2 to continue to press the elastic component 4.

[0030] The deformation of the sealing tongue 2 refers to the degree of compression deformation of the sealing tongue 2 under the action of external force, that is, the ratio of the deformation of the sealing ring after being squeezed by the elastic component 4 to its original thickness. When subjected to the same force, the smaller the deformation of the sealing tongue 2, the more difficult it is for the sealing tongue 2 to be deformed under pressure, thereby reducing the movement of the pot cover 5; the smaller the deformation of the sealing tongue 2, the more sufficient it is to compress the elastic component 4 after the sealing tongue 2 is deformed under pressure, and also ensure that the supporting elastic component 4 can abut against the pot cover 5 and the pot mouth.

[0031] In some embodiments, an anti-overflow electrode may be provided on the lower side of the pot cover 5. The anti-overflow electrode is used to detect the liquid level of the beverage inside the pot body and the generated foam. When the liquid and the foam contact the anti-overflow electrode, the anti-overflow electrode is turned on to generate an overflow signal. A metal sheet for receiving the overflow signal may be provided at the pot mouth. At this time, the elastic component 4 may be an elastic ejector installed on the pot cover 5, and the elastic ejector connects the anti-overflow electrode on the pot cover 5 and the metal sheet inside the pot mouth. When the pot cover 5 is closed with the pot mouth, the elastic ejector extends from the pot cover 5 and abuts against the metal sheet inside the pot mouth, so that the elastic ejector generates a thrust to the side away from the metal sheet (away from the elastic ejector), thereby squeezing the sealing tongue 2 away from the elastic ejector. On the other hand, the sealing tongue 2 also applies a force in a direction to the elastic ejector, thereby ensuring that the elastic ejector abuts against the metal sheet. Further, the sealing body 1 may be provided with a through hole at the corresponding position of the anti-overflow electrode, which, on the one hand, facilitates the anti-overflow electrode to pass through the sealing body 1, and on the other hand, can limit the circumferential rotation of the sealing body 1 and the sealing tongue 2.

[0032] In some embodiments, the elastic component 4 can be a micro switch for detecting whether the pot lid 5 is closed. The micro switch is installed on the pot body, and the micro switch extends from the pot mouth and faces the pot lid 5. When the pot lid 5 is closed with the pot mouth, the pot lid 5 squeezes the micro switch, thereby detecting whether the pot lid 5 is closed. When the pot lid 5 is closed, the sealing tongue 2 away from the micro switch is squeezed, and an opposite force is generated on the pot lid 5, ensuring that the pot lid 5 triggers the micro switch.

[0033] In the above-mentioned embodiment, the deformation amount of the sealing tongue 2 can be changed at least through the following embodiments.

[0034] First, by radially arranging a plurality of supporting ribs 3 between the sealing tongue 2 and the sealing body 1 on each side, the strength of the supporting ribs 3 on each side increases from the elastic component 4 to the position away from the elastic component 4.

[0035] The supporting ribs 3 are arranged between the sealing tongue 2 and the sealing body 1 on each side, so that the supporting ribs 3 can provide support for the sealing tongue 2 and also improve the rigidity of the sealing tongue 2, so that the deformation of the sealing tongue 2 squeezed by the elastic component 4 is reduced.

[0036] The greater the strength of the support rib 3, the smaller the deformation of the sealing tongue 2 at that location. In order to reduce the deformation of the sealing tongue 2 away from the elastic component 4 and to enable the sealing tongue 2 to press the elastic component 4, the strength of the support rib 3 gradually increases from the elastic component 4 to the location away from the elastic component 4, and the strength of the support rib 3 away from the elastic component 4 is greater than the strength of the support rib 3 close to the elastic component 4.

[0037] In some embodiments, when the deformation of the sealing tongue 2 is reduced, it is still necessary to ensure that the sealing tongue 2 has sufficient elasticity so that the sealing tongue 2 can fit the pot mouth and adapt to the processing error between the pot mouth and the pot cover 5; the sealing tongue 2 maintains sufficient elasticity, which is also convenient for the user to remove the pot cover 5. Therefore, from the elastic component 4 to the part away from the elastic component 4, the strength of the support ribs 3 on each side increases one by one, so that the deformation of the sealing tongue 2 gradually decreases; in the area with greater pressure, the strength of the support ribs 3 is also increased accordingly, especially in the area where the sealing tongue 2 is away from the elastic component 4, providing stronger support; in the area with less pressure, the strength of the support ribs 3 does not need to be very large, and the elasticity of the sealing tongue 2 needs to be maintained, such as the area where the sealing tongue 2 is close to the elastic component 4. Further, if the deformation of the sealing tongue 2 is sufficient to squeeze the elastic component 4, the strength of the support ribs 3 may no longer increase, and the elasticity of the sealing tongue 2 is balanced as much as possible.

[0038] In some embodiments, the supporting ribs 3 on each side are symmetrically arranged on both sides of the elastic component 4, so that the sealing tongue 2 is subjected to more uniform force, and thus the sealing tongue 2 supports the elastic component 4 more uniformly.

[0039] In some embodiments, three supporting ribs 3 may be radially arranged between the sealing tongue 2 on each side and the sealing body 1. For example, at least two supporting ribs 3 may be arranged on each side of the sealing tongue 2 away from the elastic component 4 to ensure that the sealing tongue 2 is subjected to stable force.

[0040] Furthermore, the strength of the supporting rib 3 can be changed at least by the following implementation methods.

[0041] 1.1, change the shape of the support rib 3. From the elastic component 4 to the position away from the elastic component 4, the cross-section of the support rib 3 on each side increases. The cross-section of the support rib 3 includes a horizontal cross-section (the cross-section is parallel to the horizontal plane), a radial cross-section (the cross-section coincides with the diameter of the pot cover 5) and a circumferential cross-section (the cross-section is tangent to the diameter of the pot cover 5). The size of the cross-section of the support rib 3 can be achieved by changing the length, width and thickness of the support rib 3. The cross-section of the support rib 3 can be a rectangular cross-section, a "T"-shaped cross-section or an "O"-shaped cross-section, etc.

[0042] For example, the length and width of the support rib 3 gradually increase from the elastic component 4 to the position away from the elastic component 4, thereby realizing a trend of reducing the deformation of the sealing tongue 2. The length of the support rib 3 is not greater than the length of the sealing ring, ensuring that the sealing tongue 2 contacts the pot mouth.

[0043] For example, the horizontal cross-section of the supporting rib 3 is a trapezoid as a whole, wherein in the horizontal cross-section, the large end of the trapezoid is connected to the sealing body 1, and the small end of the trapezoid is close to the edge of the sealing tongue 2, so that the edge of the sealing tongue 2 still has better elasticity.

[0044] 1.2, change the number and density of the support ribs 3. For example, from the elastic component 4 to the part away from the elastic component 4, the spacing of the support ribs 3 on each side gradually decreases, which can better disperse the extrusion force on the sealing tongue 2, increase the support of the support ribs 3 to the sealing tongue 2 away from the elastic component 4, and thus achieve a trend of reducing the deformation of the sealing tongue 2.

[0045] 1.3, change the material of the support rib 3. For example, the support rib 3 can be made of a material with higher strength.

[0046] Second, the deformation of the sealing tongue 2 can also be changed by changing the thickness of the sealing tongue 2 .

[0047] In some embodiments, the thickness of the sealing tongue 2 on each side gradually increases from the elastic component 4 to the location away from the elastic component 4. The thickness of the sealing tongue 2 increases the bending resistance of the sealing tongue 2, so that the deformation amount of the sealing tongue 2 on each side tends to decrease from the elastic component 4 to the location away from the elastic component 4, thereby facilitating the compression of the elastic component 4.

[0048] In addition, during actual use, the sealing tongue 2 can be in a variety of postures. For example, the sealing tongue 2 can be extended in the horizontal direction. For example, the longitudinal section of the sealing tongue 2 is bent and extended upward from the inside to the outside, and the sealing tongue 2 and the sealing ring together form an upward opening, which is convenient for the user to cover the pot lid 5, and can also prevent the pot lid 5 from falling when the liquid heater is tilted. In some cases, condensed water from the liquid heater can fall into the above-mentioned opening, enhancing the sealing effect of the sealing ring. In some embodiments, the support rib 3 can be provided in the opening, the inner side of the support rib 3 is connected to the sealing body 1, and the lower side and the front side of the sealing rib are connected to the sealing tongue 2, so as to better adjust the deformation of the sealing tongue 2.

[0049] In actual use, the width of the sealing tongue 2 is not less than 10 mm, thereby improving the sealing effect between the pot lid 5 and the pot mouth, and also improving the user's experience of opening and closing the lid.

[0050] In some embodiments, the sealing ring may be made of silicone.

[0051] In some embodiments, a limit block is provided on the contact surface between the sealing body 1 and the pot cover 5, and the pot cover 5 is provided with a limit groove for accommodating the limit block. When the sealing body 1 is sleeved on the pot cover 5, the limit block is placed in the limit groove, thereby preventing the sealing body 1 and the sealing tongue 2 from rotating.

[0052] In some embodiments, the sealing tongue 2 extends from both sides of the elastic component 4 along the outer peripheral side of the sealing body 1 away from the elastic component 4, so that in some cases, on the side close to the elastic component 4, an escape space for avoiding the elastic component 4 is provided between the sealing tongues 2 on both sides; on the side away from the elastic component 4, the sealing tongues 2 on both sides may be continuous, or a gap may be provided for assisting the water discharge from the spout.

[0053] In some embodiments, the sealing tongue 2 is located at the elastic component 4, which may refer to the end of the sealing tongue 2 close to the elastic component 4, or the area near the end.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
