Description

Technical Field

[0001] The utility model relates to the technical field of health-preserving kettles, in particular to a health-preserving kettle. Background Art

[0002] The electric kettles used daily are generally ordinary electric kettles that are not visible. The inner wall of the kettle is often made of metal. The outer side of the inner wall is also provided with a heat insulation layer and other protective parts. The inner wall is not in direct contact with the environment, and the temperature difference between the inner wall and the environment is small.

[0003] With the development of the times, visual health kettles are gradually becoming more and more popular. Health kettles usually consist of a power base and a detachable water boiling container. The inner wall of the water boiling container is mostly made of high borosilicate glass, and the inner bottom of the water boiling container is often made of metal. In order to achieve the visual heating effect, the inner wall often needs to be directly exposed to the environment. Compared with traditional electric kettles, the temperature difference between the inner wall of the visual health kettle and the liquid in the pot and the bottom of the inner tank is too large, which causes the bubbles on the heating surface of the inner bottom to burst very easily, generating noise.

[0004] Although the heating power of a health kettle is generally around 1000W and the noise is relatively lower than other electric kettles with higher power, with the development of the market, consumers are becoming more sensitive to heating noise. Due to the temperature difference between the glass inner wall and the heating surface, colder water flows to the heating surface, and the bubbles on the heating surface burst due to the temperature difference, causing boiling water noise, which greatly affects the user experience.

[0005] In health kettles and other electric kettles, the longitudinal cross-section of the heating tube of the earliest electric kettles is often trapezoidal. The large end of the trapezoid is in contact with the bottom of the inner pot. Only one surface of the heating tube is used for heat transfer. The heating surface area of ​​the heating tube is smaller, and the temperature of the heating surface is more concentrated. The temperature difference between the heating surface and other positions of the bottom of the inner pot is larger. During the generation of bubbles on the heating surface, the bubbles are easily affected by the temperature difference and burst, thereby generating noise.

[0006] In order to solve the problem of high noise when boiling water, the prior art proposes a boss heating structure that uses a single heating tube to increase the contact area between the heating tube and the bottom of the inner pot of the electric kettle. The boss heating structure realizes three-dimensional heating of the inner pot in the longitudinal direction, thereby increasing the area of ​​the water and the heating surface of the inner pot bottom and reducing the heat load on the heating surface. And compared with the traditional flat-bottom health kettle, the boss heating structure protrudes from the bottom of the inner pot, changing the convection circulation path of the water flow from the heating hot end to the cold end, and more eddies or turbulence can be generated at the edges or tangent surfaces of the boss, thereby improving the heating efficiency.

[0007] The prior art discloses a variety of longitudinal cross-sectional shapes of boss heating structures:

[0008] For example, the prior art CN201520068538.6 discloses a heating plate, in which an annular groove is formed in the middle of an aluminum plate (bottom of the inner tank), and the longitudinal section of the groove is rectangular, and the longitudinal section of the rectangular groove includes a vertical plane and a horizontal plane. However, the right angle between the vertical plane and the bottom of the inner tank in the rectangular longitudinal section makes the bottom of the inner tank difficult to clean, and is also difficult to make during the stamping process of the groove. More importantly, when the inner tank is boiling water, the liquid flow efficiency at the right angle between the vertical plane and the bottom of the inner tank is low, which causes heat concentration at the right angle, making the bubbles more likely to burst.

[0009] For example, the prior art patent document CN200610062819.6 discloses a liquid heater, which mainly discloses a ring-shaped boss with a "human" cross-section. The space at the top of the "human" cross-section boss is small, and when the bubbles move to the top of the boss, some bubbles do not have enough space to grow into large bubbles, and the effect of bubble aggregation and growth is limited.

[0010] For example, the prior art CN202221657704.2 discloses a liquid heater, a chassis assembly and a liquid heating container, mainly disclosing an annular groove with a semicircular cross-section. On a curved surface, bubbles may detach earlier than on a flat surface because the surface shape provides a path that is easier for bubbles to move and detach, but it is not conducive to small bubbles having enough space to grow into large bubbles.

[0011] The grooves (relative to the installation of the heating tube) or bosses (relative to the heating surface) with different cross-sections disclosed in the above-mentioned prior art are all improvements based on the traditional electric kettle.

[0012] Although the above-mentioned prior art increases the heating area, it does not take into account the special technical problems caused by the temperature difference between the glass liner wall and the heating surface in the use environment of the health kettle. The temperature of the groove or boss surface is almost the same. During the convection process, the colder water flowing through the glass liner wall flows to the hotter heating surface on the groove or boss. The bubbles are subject to a large temperature difference and are more likely to break. Moreover, before the colder water reaches the boss with a higher temperature, there is no structure or space to allow the colder water to heat up in advance, which easily causes the bubbles on the boss to come into contact with water with a large temperature difference, thereby breaking. The prior art solution has limited improvement in reducing the temperature difference between the glass liner wall and the heating surface, and it is difficult to further improve the noise reduction effect of the health kettle. Utility Model Content

[0013] The utility model aims to provide a health-preserving kettle to solve the problem in the prior art that, when the boss heating structure improves the heating efficiency, the temperature difference between the colder water flowing through the glass inner wall and the heating surface of the boss is large, which causes the bubbles to easily break and the noise to be large.

[0014] The embodiment of the present application provides a health pot, comprising an inner liner, wherein the inner liner comprises an inner liner wall made of glass material and an inner liner bottom made of metal material, a heating pipe is arranged at the bottom of the inner liner bottom, and the inner liner bottom comprises a first transverse wall located at the center of the bottom, and a boss located outside the first transverse wall;

[0015] The boss includes a first inclined wall inclined upward and outward from the outer edge of the first transverse wall, a second transverse wall extending laterally outward from the upper edge of the first inclined wall, and a second inclined wall inclined downward and outward from the second transverse wall, wherein the second transverse wall is higher than the first transverse wall;

[0016] The first inclined wall, the second transverse wall and the second inclined wall form an installation cavity opening downward, and the heating pipe is arranged in the installation cavity and fits with the wall of the installation cavity;

[0017] The outer edge of the second inclined wall is also provided with a mounting groove with an opening facing upward, and the mounting groove contains a sealing material connected to the lower edge of the inner liner wall. The length of the second inclined wall is greater than that of the first inclined wall.

[0018] In some embodiments of the present invention, the lower edge of the inner container wall is located on a side of the installation groove away from the second inclined wall.

[0019] In some embodiments of the present invention, the lower end surface of the heating tube is lower than the bottom end of the first inclined wall, and the lower end surface of the heating tube is higher than the bottom end of the second inclined wall.

[0020] In some embodiments of the present invention, the lower edge of the inner container wall does not contact the mounting groove.

[0021] In some embodiments of the present invention, the inner tank wall includes a first longitudinal wall located in the mounting groove, and a third transverse wall extending outward from an upper edge of the first longitudinal wall, and the third transverse wall is not higher than the first transverse wall.

[0022] In some embodiments of the present invention, the lower end surface of the third transverse wall is not lower than the lower end surface of the heating tube.

[0023] In some embodiments of the present invention, a rounded corner is provided between the second transverse wall and the second inclined wall.

[0024] In some embodiments of the present invention, the slope of the second inclined wall is the same as the slope of the first inclined wall.

[0025] In some embodiments of the present invention, the length of the second inclined wall is greater than the length of the second transverse wall.

[0026] In some embodiments of the present invention, connecting cold pins are provided at both ends of the heating tube, and the connecting cold pins extend in a direction away from the mounting groove.

[0027] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0028] In this embodiment, there is a second transverse wall on the upper side of the first inclined wall and the second inclined wall. During the water boiling process, in addition to some bubbles generated by the second transverse wall, some bubbles on the inclined surface can move from the inclined surface to the second transverse wall. The surface tension distribution of bubbles on the plane is more uniform than that on the inclined surface, providing a relatively stable accommodation space for bubbles that do not have time to escape, and improving the noise reduction effect of the health kettle when the height of the boss cannot be very high in the current process.

[0029] The length of the second inclined wall is greater than that of the first inclined wall. The heat of the heating pipe can be transferred more along the second inclined wall, so that the heat conduction area of ​​the second inclined wall is larger, the temperature accumulated on the second inclined wall is less, the temperature difference between the second inclined wall and the inner wall is smaller, and the probability of bubbles near the inner wall bursting is smaller. At the same time, the second inclined wall is longer, and the water flow has enough space to heat up, reducing the temperature difference to which the bubbles are subjected.

[0030] The lower edge of the inner pot wall is installed in the installation groove, and the installation groove is filled with sealing material. The lower edge of the inner pot wall is installed in the installation groove through the sealing material. The inner pot wall is connected to the second inclined wall through the sealing material and the installation groove, avoiding contact between the inner pot wall and the second inclined wall. At the same time, the installation groove and the sealing material form a temperature transition zone between the second transverse wall and the inner pot wall. When boiling water, the relatively cold water flowing through the inner pot wall can first flow through the upper side of the installation groove to be heated in advance by contact or convection, and then flow to the second inclined wall, extending the flow path of the water flow, so that the water flow is heated in advance before flowing to the second inclined wall.

DETAILED DESCRIPTION

[0035] 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.

[0036] Embodiment 1

[0037] like Figure 1-3 As shown, in this embodiment, an inner tank is included, the inner tank includes an inner tank wall 2 made of glass material and an inner tank bottom 1 made of metal material, a heating tube 3 is arranged at the bottom of the inner tank bottom 1, and the inner tank bottom 1 includes a first transverse wall 102 located at the center of the bottom, and a boss 101 located outside the first transverse wall 102.

[0038] In some embodiments of the present invention, the inner pot wall 2 is often made of high temperature resistant transparent borosilicate glass, which is convenient for users to observe in real time when boiling water or stewing. The inner pot bottom 1 is usually made of stainless steel or aluminum alloy with good thermal conductivity and easy processing.

[0039] The inner tank bottom 1 comprises a first transverse wall 102 located at the center of the bottom, which is used for mounting a coupler and other components of a thermostat.

[0040] The outer side of the first transverse wall 102 can be punched to form a boss 101, and the bottom of the boss 101 forms a mounting cavity 103 for mounting the heating tube 3. The heating tube 3 can be in contact with the inner wall of the mounting cavity 103 through solder or heat conductive material. The above-mentioned heating tube 3 is mostly a C-shaped or annular heating tube 3. In the top view, the boss 101 mounting cavity 103 can be set to be C-shaped or annular according to the structure of the heating tube 3.

[0041] In this embodiment, the boss 101 includes a first inclined wall 111 inclined upward and outward from the outer edge of the first transverse wall 102, a second transverse wall 112 extending laterally outward from the upper edge of the first inclined wall 111, and a second inclined wall 113 inclined downward and outward from the second transverse wall 112, wherein the second transverse wall 112 is higher than the first transverse wall 102; the first inclined wall 111, the second transverse wall 112 and the second inclined wall 113 form an installation cavity 103 opening downward, and the heating tube 3 is arranged in the installation cavity 103 and is in contact with the wall of the installation cavity 103.

[0042] In some embodiments of the present invention, the second transverse wall 112 is higher than the first transverse wall 102, so that the boss 101 protrudes upward from the first transverse wall 102. In the longitudinal section, the second transverse wall 112 is provided on the top of the boss 101, and the width of the boss 101 gradually increases from the second transverse wall 112 downward, forming an inclined first inclined wall 111 and a second inclined wall 113, the first inclined wall 111 is close to the first transverse wall 102, and the second inclined wall 113 is close to the inner pot wall 2. The heating tube 3 is fitted with the first inclined wall 111, the second inclined wall 113 and the second transverse wall 112, and the contact area between the boss 101 of the inner pot bottom 1 and the heating tube 3 is increased while the surface area of ​​the heating tube 3 remains unchanged.

[0043] Compared with the rectangular boss 101, the first inclined wall 111 and the second inclined wall 113 of the present embodiment, in addition to increasing the heating area, are conducive to the bubbles to converge into large bubbles along the first inclined wall 111 and the second inclined wall 113, thereby reducing the probability of bubble bursting. When boiling water, some bubbles will be generated from the first inclined wall 111 and the second inclined wall 113 (hereinafter collectively referred to as inclined surfaces for the sake of convenience), and the bubbles will be affected by the surface tension on the inclined surfaces. At the same time, the buoyancy of the bubbles is different from the normal direction of the inclined surfaces, and some of the bubbles will slide upward along the inclined surfaces and converge with other bubbles to form large bubbles.

[0044] Among them, the curvature of large bubbles is smaller than that of small bubbles. The Young-Laplace equation shows that the surface tension is inversely proportional to the radius of curvature. The greater the surface tension, the greater the pressure difference and the easier it is to break. This means that small bubbles are more likely to break than large bubbles.

[0045] To some extent, due to the distribution of surface tension, the size required for the bubble to break away from the inclined surface is smaller, and the bubble is relatively easy to break away from. However, due to the processing technology and the influence of the height of the heating tube, the height of the boss 101 (from the upper edge of the second transverse wall 112 to the upper edge of the first transverse wall 102) in this embodiment is relatively low, and the height and length of the first inclined wall 111 and the second inclined wall 113 are relatively small. The height of the inclined surface is insufficient, and when the bubble reaches the upper end of the inclined surface, the bubble still does not reach the buoyancy required for breaking away. At this time, if there is not enough space to accommodate the bubble to be broken away, the bubble is more likely to break due to the uneven distribution of the surface tension of the inclined surface (compared to the plane).

[0046] Therefore, compared with the "human" shaped cross-section boss 101 or the semicircular cross-section boss 101 of the prior art, the first inclined wall 111 and the second inclined wall 113 of this embodiment have a second transverse wall 112 on the upper side. During the water boiling process, in addition to the second transverse wall 112 generating some bubbles, some bubbles on the inclined surface can move from the inclined surface to the second transverse wall 112. The surface tension distribution of bubbles on the plane is more uniform than that on the inclined surface, providing a relatively stable accommodation space for bubbles that do not have time to escape, and improving the noise reduction effect of the health pot when the height of the boss 101 cannot be very high in the current process.

[0047] Except for a few bubbles that burst directly, the generation, movement and growth of bubbles on the inclined surface include at least the following two situations: 1. Bubbles are generated on the inclined surface, and move along the inclined surface to converge into large bubbles, and finally the bubbles break away from the inclined surface on the inclined surface; 2. Bubbles are generated on the inclined surface, and move along the inclined surface to converge, but their own size and buoyancy are not enough to break away from the inclined surface, then the bubbles continue to move to the second transverse wall 112, so that their own surface tension distribution is more stable, enough to converge into large bubbles on the plane and break away, and reduce the bubbles on the inclined surface. The bubbles burst because they do not have time to break away. Therefore, compared with the prior art, the first inclined wall 111, the second inclined wall 113 and the second transverse wall 112 in this embodiment can not only realize the convergence of bubbles into large bubbles on the first inclined wall 111 and the second inclined wall 113, but also realize the provision of growth space for small bubbles that do not have time to grow into large bubbles through the second transverse wall 112, and improve the noise reduction effect of the health pot when the height of the current process boss 101 cannot be very high.

[0048] In some embodiments, the longitudinal section of the heating tube 3 is a trapezoid, the small end of the trapezoid fits with the second transverse wall 112, and the two side walls of the trapezoid fit with the first inclined wall 111 and the second inclined wall 113 respectively. Thus, under the same circumference, the contact area between the heating tube 3 and the boss 101 is large. At the same time, the small end of the heating tube 3 fits with the second transverse wall 112, which also facilitates the installation of the heating tube 3 and the inner tank bottom 1.

[0049] In some embodiments, influenced by existing processes such as stamping, the first inclined wall 111 , the second inclined wall 113 , and the second transverse wall 112 may all be straight walls, or slightly curved walls due to process reasons.

[0050] In this embodiment, the outer edge of the second inclined wall 113 is also provided with an installation groove 104 with an opening facing upward, and the installation groove 104 contains a sealing material 141 connected to the lower edge of the inner tank wall 2. The length of the second inclined wall 113 is greater than that of the first inclined wall 111.

[0051] Compared with the traditional electric kettle, the glass inner wall 2 of the present embodiment is directly in contact with the low temperature (compared with the water boiling temperature) environment outside, and the temperature difference between the inner wall 2 and the boss 101, especially the bottom of the second inclined wall 113, is relatively large. During the convection process of boiling water, part of the water flows through the inner wall 2 with a lower temperature to the second inclined wall 113, and the surface temperature of the second inclined wall 113 is relatively high. For the bubbles on the second inclined wall 113, the temperature of the contact surface between the bubbles and the second inclined wall 113 is relatively high, while the temperature of the side of the bubbles in contact with the water flowing through the inner wall 2 is relatively low, which can easily cause the bubbles to burst due to the temperature difference.

[0052] In some embodiments of the present invention, the boss 101 structure increases the contact area with the heating tube 3 and also increases the contact area with water, so that the heat of the heating tube 3 can be transferred to the water more evenly; the temperature difference between the boss 101 (especially the second inclined wall 113) and the inner tank wall 2 reduces the probability of bubble bursting.

[0053] Different from the prior art, in some embodiments, the length of the second inclined wall 113 is greater than the length of the first inclined wall 111. The heat of the heating pipe 3 can be transferred more along the second inclined wall 113, so that the heat conduction area of ​​the second inclined wall 113 is larger, the temperature accumulated on the second inclined wall 113 is smaller, the temperature difference between the second inclined wall 113 and the inner tank wall 2 is smaller, and the probability of the bubbles near the inner tank wall 2 bursting is smaller. At the same time, the second inclined wall 113 is longer, and the water flow has enough space to heat up, reducing the temperature difference to which the bubbles are subjected.

[0054] On the other hand, the existing health pot glass inner liner wall 2 and the metal inner liner bottom 1 are often connected by mechanical clamping or interlocking, wherein the inner liner wall 2 and the inner liner bottom 1 may be in direct contact. When heat is transferred along the second inclined wall 113 toward the lower end of the inner liner wall 2, the temperature at the lower end of the inner liner wall 2 is too high, and the glass material is subjected to a large temperature difference, which may bring potential safety hazards.

[0055] Different from the prior art, in some embodiments, the lower edge of the inner pot wall 2 is installed in the installation groove 104, and the installation groove 104 is filled with a sealing material 141, and the lower edge of the inner pot wall 2 is installed in the installation groove 104 through the sealing material 141. The inner pot wall 2 is connected to the second inclined wall 113 through the sealing material 141 and the installation groove 104, thereby avoiding contact between the inner pot wall 2 and the second inclined wall 113. At the same time, the installation groove 104 and the sealing material 141 form a temperature transition zone between the second transverse wall 112 and the inner pot wall 2. When boiling water, the relatively cold water flowing through the inner pot wall 2 can first flow through the upper side of the installation groove 104 to be heated in advance by contact or convection, and then flow to the second inclined wall 113, thereby extending the flow path of the water flow, so that the water flow is heated in advance before flowing to the second inclined wall 113.

[0056] In some embodiments, the sealing material 141 may be silicone glue or silica gel.

[0057] The lower edge of the inner tank wall 2 and the inner wall of the installation groove 104 are filled with sealing material 141. However, in actual use, it is found that due to the influence of the shape or structure of the inner tank wall 2, the heat transfer between the water flow and the installation groove 104 or the sealing material 141, the temperature rise of the water flow before reaching the second inclined wall 113 is insufficient. At the same time, it is also found that if the lower edge of the inner tank wall 2 is too close to the second inclined wall 113, when the sealing material 141 is filled, the lower edge of the inner tank wall 2 is easy to block the installation groove 104, affecting the installation accuracy.

[0058] In some implementations of this embodiment, the lower edge of the inner container wall 2 is located at a side of the installation groove 104 away from the second inclined wall 113 .

[0059] In the above embodiment, the distance between the lower edge of the inner tank wall 2 and the second inclined wall 113 is increased, the flow path of the colder water flow in the inner tank wall 2 is further increased, the temperature difference between the water flow and the second inclined wall 113 is reduced, and the noise reduction performance of the health pot is further improved.

[0060] The lower edge of the inner wall 2 is away from the second inclined wall 113, providing space for filling the sealing material 141 or other processing steps. In actual use, the distance between the lower edge of the inner wall 2 and the inner wall of the mounting groove 104 can be adjusted according to the structure of the inner wall 2, the mounting groove 104 and the second inclined wall 113.

[0061] In some implementations, the minimum distance between the lower edge of the inner container wall 2 and the inner wall of the mounting groove 104 (the side close to the second inclined wall 113 ) is greater than or equal to 5 mm.

[0062] In the health pot, the temperature at the center of the inner tank and the temperature on one side of the glass inner tank wall 2 are very different, the temperature at the center of the inner tank is higher, and the temperature on one side of the glass inner tank wall 2 is higher. The water in the health pot flows spontaneously from the lower temperature to the higher temperature to form a convection cycle, which is an important way for the health pot to heat water. The faster the convection cycle, the more conducive it is to make the colder water flow be heated quickly and evenly.

[0063] In the prior art, the heat transfer area of ​​the heating tube 3 and the two sides of the boss 101 is the same, and the temperature of the inner tank wall 2 close to the inner tank wall 2 is lower, and the water flow cannot be fully guided to generate convection, resulting in the water flow with lower temperature on the side of the inner tank wall 2 to heat up slowly, and the bubbles are subject to a large temperature difference and are easily broken.

[0064] In some implementations of this embodiment, the lower end surface of the heating tube 3 is lower than the bottom end of the first inclined wall 111 , and the lower end surface of the heating tube 3 is higher than the bottom end of the second inclined wall 113 .

[0065] In the above embodiment, the contact area between the heating tube 3 and the second inclined wall 113 is greater than the contact area with the first inclined wall 111. In combination with the fact that the length of the second inclined wall 113 in this embodiment is greater than the length of the first inclined wall 111, the colder water flow on one side of the inner tank wall 2 has sufficient heat source and space for sufficient convection, thereby further reducing the temperature difference between the water flow and the second inclined wall 113 and improving the noise reduction effect.

[0066] In some implementations of this embodiment, the lower edge of the inner container wall 2 does not contact the mounting groove 104 .

[0067] In the above embodiment, the inner wall 2 is made of glass, which is brittle and easily shattered after being hit, causing safety hazards. The lower edge of the inner wall 2 does not contact the mounting groove 104 to prevent the glass inner wall 2 from shattering after the health pot is hit.

[0068] In some implementations of this embodiment, the inner tank wall 2 includes a first longitudinal wall 201 located in the mounting groove 104 and a third transverse wall 202 extending outward from an upper edge of the first longitudinal wall 201 , and the third transverse wall 202 is not higher than the first transverse wall 102 .

[0069] In the above embodiment, in the convection cycle, the flow direction of the water flow is affected by temperature and density: the higher the temperature of the water flow, the smaller the density, and the water flow moves upward; the lower the temperature of the water flow, the greater the density, and the water flow moves downward.

[0070] The inner wall 2 is made of glass and is in direct contact with the external environment. Therefore, the temperature of the third transverse wall 202 is also lower than that of the first transverse wall 102. The third transverse wall 202 is equal to or lower than the first transverse wall 102, which is conducive to the colder water flowing upward from the third transverse wall 202, realizing efficient vertical convection circulation, improving heating efficiency, making the convection circulation in the health pot more sufficient, and improving the noise reduction effect.

[0071] In some embodiments, the outer edge of the third transverse wall 202 is provided with an outer side wall 203 extending upward, the first longitudinal wall 201 and the inner liner wall 2 are composed of the third transverse wall 202 and the outer side wall 203, and the outer side wall 203 is a longitudinal wall or an arc wall.

[0072] In some implementations of this embodiment, the lower end surface of the third transverse wall 202 is not lower than the lower end surface of the heating tube 3 .

[0073] In the above embodiment, the third transverse wall 202 is prevented from being far away from the hot end, so that the colder water flows from the third transverse wall 202 to the hotter second inclined wall 113 .

[0074] In some implementations of this embodiment, a rounded corner is provided between the second transverse wall 112 and the second inclined wall 113 .

[0075] In the above embodiment, the curvature of the fillet changes relatively continuously, which is beneficial for the bubbles to flow along the second inclined wall 113 to the second transverse wall 112 , thereby reducing the resistance to the bubble flow.

[0076] In some implementations of this embodiment, the slope of the second inclined wall 113 is the same as the slope of the first inclined wall 111 .

[0077] In the above embodiment, the longitudinal section of the actually used heating tube 3 is mostly trapezoidal, and the second inclined wall 113 has the same slope as the first inclined wall 111, which is conducive to the installation of the trapezoidal heating tube 3. It is also conducive to the bubbles of the second inclined wall 113 and the first inclined wall 111 moving to the second transverse wall 112 at a similar rate, thereby improving the noise reduction effect.

[0078] In some embodiments, the included angle between the second inclined wall 113 and the first inclined wall 111 and the horizontal plane may be 60° to 80°.

[0079] In some implementations of this embodiment, the length of the second inclined wall 113 is greater than the length of the second transverse wall 112 .

[0080] In the above embodiment, the shape of the boss 101 is mainly affected by the length of the second inclined wall 113 and the length of the second transverse wall 112. When the length of the second inclined wall 113 is greater than the length of the second transverse wall 112, the height of the boss 101 in the vertical direction increases, which is beneficial to heating the water flow in the longitudinal direction and further improving the uniformity of boiling water in the health kettle.

[0081] In some implementations of this embodiment, connecting cold pins are provided at both ends of the heating tube 3 , and the connecting cold pins extend in a direction away from the installation cavity 103 .

[0082] In the above embodiment, when the cold pin is connected to the cable, the cold pin extends downward relative to the bottom 1 of the inner tank, which can reduce the depth of the cable in the installation cavity 103, reduce the probability of the cable touching the inner wall of the installation cavity 103, and prevent the cable from being heated and affecting the stability of the connection.

[0083] 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.
