Description

Technical Field

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

[0002] At present, liquid heaters on the market usually include a kettle body with an open bottom and a kettle seat fixed to the bottom end of the kettle body. For example, the kettle body of a health-preserving kettle is mostly made of glass or ceramic. Because glass and ceramic are relatively brittle, in order to ensure effective sealing between the kettle body and the kettle seat and avoid damage to the kettle body, there are roughly two ways to connect the kettle body and the kettle seat: one is to set a silicone piece between the kettle body and the kettle seat to clamp and seal; the other is to set a groove in the kettle seat, pour glue into the groove, and then insert the kettle body into the groove and wait for curing and sealing. For example, the prior art CN208463669U discloses a new type of health-preserving kettle body, including a kettle body and a heating chassis, the kettle body is made of glass, and an annular groove is provided on the heating chassis. The lower end of the kettle body is provided with a plug-in portion, which is inserted into the annular groove, and welding glue is poured between the inner wall of the annular groove and the plug-in portion. A connection ring is provided at the connection between the plug-in portion and the kettle body, which extends to the inside of the kettle body and is connected to the heating chassis. The top surface of the hot bottom plate is tightly attached to the protruding part, and the lower end of the kettle body and the outer side of the heating bottom plate are covered with a bottom shell; for another example, the prior art CN212346221U discloses a new type of sealing mechanism for a kettle body and a kettle seat, comprising a kettle body and a kettle seat, the kettle body is plugged into the upper surface of the corresponding kettle seat, the kettle body comprises a glass cup body and an inner liner, the inner side of the glass cup body is formed with an inner liner, the upper end of the glass cup body is provided with a spout, the spout is connected with the inner liner, the inner side of the kettle seat is provided with a thermostat, the thermostat is located at the middle end of the kettle seat, a heating plate is also provided on the kettle seat, a heating plate silicone is provided at the gap between the heating plate and the glass cup body, and the bottom end of the glass cup body is connected to the kettle seat by glue, and the heating plate silicone is provided at the gap between the heating plate and the glass cup body and the heating plate silicone is bonded to the heating plate, so that the heating plate silicone can seal the kettle body and the kettle seat, thereby preventing foreign objects from falling into the gap and affecting the user experience, and greatly improving the user experience satisfaction.

[0003] However, in the above-mentioned method of sealing the glass cup body and the heating plate with glue, due to the size difference between the glass cup body and the heating plate, there will be a tolerance in the depth of the gap formed between the glass cup body and the heating plate after assembly. If too much glue is injected into the glue injection groove, it will overflow when the glass cup body and the heating plate are assembled, causing the glue to flow to other areas that do not require sealing, affecting the assembly or use of other parts. If too little glue is injected into the glue injection groove, it will affect the sealing effect between the glass cup body and the heating plate, and after curing, the glue will form an uneven structure on the inside of the glass cup body. Since the distance between the inner side surface of the glass cup body and the inner circle side surface of the glue injection groove is small, it is easy to produce sanitary dead corners. Utility Model Content

[0004] The purpose to be achieved by the utility model is to provide a liquid heater, which solves the problem that when the kettle body and the heating chassis are sealed and connected by glue, there is too much glue used, which is easy to overflow and affect the assembly or use of other parts; or too little glue is used to form sanitary dead corners. It can effectively prevent the glue from flowing to other areas and affecting the assembly or use of other parts, and can improve the flatness of the glue on the inner side of the kettle body, effectively reducing sanitary dead corners.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a liquid heater, including a kettle body, the kettle body including a kettle body with an open bottom end and a heating base fixed to the bottom end of the kettle body, the heating base including a main body part provided with a heating tube and an outer ring part provided with an annular glue injection groove, the bottom end of the kettle body is inserted into the annular glue injection groove for connection, the outer ring part is also provided with an overflow glue groove, the overflow glue groove is located on the outer peripheral side of the annular glue injection groove, the outer ring part forms two circles of reinforcement structure through the overflow glue groove and the annular glue injection groove, the outer circle height of the annular glue injection groove is H1, the inner circle height is H2, H1<H2.

[0006] After adopting the above technical scheme, the utility model has the following advantages: by arranging an overflow glue groove on the outer peripheral side of the annular glue injection groove, and the outer ring height of the annular glue injection groove is smaller than the inner ring height, wherein the outer ring of the annular glue injection groove is close to the overflow glue groove, and the inner ring of the annular glue injection groove is close to the main part of the heating chassis; when the annular glue injection groove is filled with glue, the height difference formed by the outer ring and the inner ring can make the glue overflow to the outside and flow into the overflow glue groove; the overflow glue groove can collect the overflowed glue, effectively preventing the glue from flowing to the main part or other areas of the heating chassis; at the same time, the excess glue in the annular glue injection groove is discharged in an overflow manner, which can ensure that the overall liquid level of the glue remaining in the annular glue injection groove remains flat; after the bottom end of the kettle body is inserted into the annular glue injection groove, the outer side of the bottom end of the kettle body and the annular glue injection groove will be Part of the glue between the outer circle side surfaces of the groove is squeezed out of the annular glue injection groove, and part of the glue located between the inner side surface of the bottom end of the kettle body and the inner circle side surface of the annular glue injection groove will slightly raise the liquid level and be slightly lower than or basically level with the inner circle top of the annular glue injection groove, thereby improving the flatness of the glue on the inner side of the kettle body. The flat inner side of the kettle body is not prone to sanitary dead corners and is easier to clean; if H1≥H2, the glue overflowing from the annular glue injection groove after the kettle body and the heating chassis are assembled will find it difficult to flow into the overflow groove, but may flow to the main part of the heating chassis; the two-circle reinforcement structure formed by the overflow groove and the annular glue injection groove can improve the structural strength of the heating chassis, better support and fix the kettle body, thereby improving the stability and durability of the liquid heater.

[0007] Furthermore, H2-H1≤3mm.

[0008] When adopting the above-mentioned technical solution, the height difference between the inner circle and the outer circle of the annular glue injection groove should not be too large, so as to avoid the glue liquid level on the inner side of the pot body being too low relative to the top of the inner circle of the annular glue injection groove, which would produce an annular groove that is difficult to clean.

[0009] Furthermore, H2-H1=1 mm.

[0010] By adopting the above-mentioned technical solution, a small height difference is formed between the inner circle and the outer circle of the annular glue injection groove, which can effectively guide the excess glue to flow to the overflow glue groove, and at the same time make the glue on the inside of the pot body basically level with the top of the inner circle of the annular glue injection groove, so that the glue on the inside of the pot body will not form a large depression relative to the top of the inner circle of the annular glue injection groove, thereby forming a sanitary dead corner that is difficult to clean.

[0011] Furthermore, a retaining ring is provided between the outer ring portion and the main body portion, and the top end of the retaining ring is higher than the upper surface of the main body portion.

[0012] By adopting the above-mentioned technical solution, the height of the retaining ring limits the flow direction of the glue, which can prevent the glue from overflowing to the main part of the heating chassis during the pouring process.

[0013] Furthermore, the upper surface of the retaining ring is smoothly connected to the inner ring side surface of the annular glue injection groove and is smoothly connected to the upper surface of the main body part.

[0014] By adopting the above-mentioned technical solution, a smooth connection is achieved without any sharp edges, so that the surface of the connection is smooth and easy for users to clean.

[0015] Furthermore, the bottom end of the pot body is a connecting end inserted downward into the annular glue injection groove, the distance from the connecting end to the inner circle side of the annular glue injection groove is S1, and the distance from the connecting end to the outer circle side of the annular glue injection groove is S2, S1>S2.

[0016] By adopting the above-mentioned technical solution and designing S1>S2, when the connecting end is inserted, the excess glue in the annular glue injection groove will overflow outward instead of flowing inward and overflowing to the main part of the heating chassis.

[0017] Furthermore, the kettle body includes a connecting end inserted downward into the annular glue injection groove and a transverse portion extending outward relative to the connecting end, the transverse portion being connected to the top end of the connecting end. The kettle body also includes a bottom cover, the top end of the bottom cover is connected to the outer periphery of the transverse portion and forms a accommodating space for accommodating the overflow glue groove between the connecting end.

[0018] By adopting the above-mentioned technical solution, the connection end, the transverse part and the bottom cover are interconnected to form a stable connection structure, which can provide a stable support for the liquid heater, thereby maintaining the integrity and stability of the kettle body.

[0019] Furthermore, the surface of the glue overflow groove is a smooth curved surface.

[0020] By adopting the above-mentioned technical solution, the surface of the glue overflow groove is designed to be a smooth curved surface, which helps the glue to flow and distribute evenly in the glue overflow groove, and avoids the glue from gathering in a certain place of the glue overflow groove and overflowing the glue overflow groove.

[0021] Furthermore, the bottom surface of the overflow glue groove is arc-shaped.

[0022] By adopting the above-mentioned technical solution, the bottom surface of the overflow glue groove is designed to be arc-shaped, which reduces the resistance of the glue flowing in the groove and helps the glue to flow evenly in the overflow glue groove.

[0023] Furthermore, the depth D1 of the glue overflow groove is smaller than the depth D2 of the annular glue injection groove.

[0024] By adopting the above-mentioned technical solution, the depth of the annular glue injection groove is greater than the depth of the overflow glue groove. While ensuring that the amount of glue poured into the annular glue injection groove can achieve effective sealing between the kettle body and the heating chassis, it avoids excessive glue being wasted during the assembly process, thereby improving the utilization rate of the glue and avoiding the difficulty of assembly and interference caused by designing the overflow glue groove too large.

[0034] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0035] like Figures 1 to 5As shown, the utility model provides a liquid heater, including a kettle body 1, the kettle body 1 includes a kettle body 2 with an open bottom end and a heating bottom plate 3 fixed to the bottom end of the kettle body 2, the heating bottom plate 3 includes a main body part 32 provided with a heating pipe and an outer ring part 31 provided with an annular glue injection groove 311, the bottom end of the kettle body 2 is inserted into the annular glue injection groove 311 for connection, the outer ring part 31 is also provided with an overflow glue groove 312, the overflow glue groove 312 is located on the outer peripheral side of the annular glue injection groove 311, and the outer ring part 31 forms a two-circle reinforcement structure through the overflow glue groove 312 and the annular glue injection groove 311 The outer ring height of the annular glue injection groove 311 is H1, and the inner ring height is H2, H1<H2, wherein the outer ring of the annular glue injection groove 311 is close to the overflow glue groove 312, and the inner ring of the annular glue injection groove 311 is close to the main part 32 of the heating chassis 3. When the annular glue injection groove 311 is filled with glue, the height difference formed by the outer ring and the inner ring can make the glue overflow to the outside and flow into the overflow glue groove 312. The overflow glue groove 312 can collect the overflowed glue, effectively preventing the glue from flowing to the main part 32 or other areas of the heating chassis 3, and at the same time, the annular glue injection groove 311 is discharged in an overflow manner. The excess glue in the glue injection groove 311 can ensure that the overall liquid level of the glue remaining in the annular glue injection groove 311 remains flat. After the bottom end of the pot body 2 is inserted into the annular glue injection groove 311, part of the glue between the outer side of the bottom end of the pot body 2 and the outer ring side of the annular glue injection groove 311 will be squeezed out of the annular glue injection groove 311, while part of the glue between the inner side of the bottom end of the pot body 2 and the inner ring side of the annular glue injection groove 311 will slightly raise the liquid level and be slightly lower than the inner ring top of the annular glue injection groove 311 or basically maintain the same level as the inner ring top of the annular glue injection groove 311. flat, thereby improving the flatness of the glue on the inner side of the kettle body 2. The flat inner side of the kettle body 2 is not prone to sanitary dead corners and is easier to clean; if H1≥H2, the glue overflowing from the annular glue injection groove 311 after the kettle body 2 and the heating chassis 3 are assembled will find it difficult to flow into the overflow glue groove 312, but may flow to the main part 32 of the heating chassis 3; the two-circle reinforcement structure formed by the overflow glue groove 312 and the annular glue injection groove 311 can improve the structural strength of the heating chassis 3, and can better support and fix the kettle body 2, thereby improving the stability and durability of the liquid heater.

[0036] In this embodiment, the height difference between the outer circle height H1 and the inner circle height H2 of the annular glue injection groove 311 is designed to be in the range of 0mm<H2-H1≤3mm, and the height difference formed by the inner circle and the outer circle of the annular glue injection groove 311 should not be too large to avoid the glue liquid level on the inner side of the pot body 2 being too low relative to the top of the inner circle of the annular glue injection groove 311, which will produce an annular groove that is difficult to clean.

[0037] Specifically, in the present embodiment, H2-H1=1mm, and a small height difference is formed between the inner circle and the outer circle of the annular glue injection groove 311, which can effectively guide the excess glue to flow to the overflow glue groove 312, and at the same time make the glue on the inner side of the kettle body 2 basically level with the top of the inner circle of the annular glue injection groove 311, so that the glue on the inner side of the kettle body 2 will not form a large depression relative to the top of the inner circle of the annular glue injection groove 311, thereby forming a sanitary dead corner that is difficult to clean.

[0038] Specifically, the surface of the overflow glue groove 312 is a smooth curved surface. The surface of the overflow glue groove 312 is designed to be a smooth curved surface, which helps the glue to flow and distribute evenly in the overflow glue groove 312 and avoids the glue from gathering in a certain place of the overflow glue groove 312 and overflowing the overflow glue groove 312.

[0039] Specifically, the bottom surface of the overflow glue groove 312 is arc-shaped. The bottom surface of the overflow glue groove 312 is designed to be arc-shaped, which reduces the resistance of the glue flowing in the overflow glue groove 312 and helps the glue to flow evenly in the overflow glue groove 312.

[0040] Specifically, the depth D1 of the overflow glue groove 312 is less than the depth D2 of the annular glue injection groove 311. The depth of the annular glue injection groove 311 is greater than the depth of the overflow glue groove 312, which ensures that the amount of glue poured into the annular glue injection groove 311 can achieve effective sealing between the kettle body 1 and the heating chassis 3, while avoiding excessive glue being wasted during the assembly process, thereby improving the utilization rate of the glue and avoiding the overflow glue groove 312 being designed too large to increase the difficulty of assembly and cause interference. If D1 ≥ D2, the amount of glue used and the difficulty of assembly will increase.

[0041] In order to further prevent unnecessary splashing of glue, in this embodiment, a retaining ring 313 is provided between the outer ring portion 31 and the main body portion 32, and the top of the retaining ring 313 is higher than the upper surface of the main body portion 32.

The smooth connection method has no edges and corners, so that the surface of the connection is smooth and easy for users to clean. Designing such a connection method can also avoid the formation of cracks at the connection between the upper surface of the retaining ring 313 and the annular glue injection groove 311, thereby reducing the risk of glue overflowing from the connection. At the same time, the smooth connection method has no edges and corners, so that the surface of the connection is flat, and the glue will not stay at the connection and thus flow smoothly into the overflow groove 312.

[0044] In addition, the kettle body 2 further includes a connecting end 21 inserted downward into the annular glue injection groove 311 and a transverse portion 22 extending outward relative to the connecting end 21, the transverse portion 22 being connected to the top of the connecting end 21, and the kettle body 1 further includes a bottom cover 4, the top of the bottom cover 4 being connected to the outer periphery of the transverse portion 22 and forming a receiving space for receiving the overflow glue groove 312 with the connecting end 21. The connection between the connecting end 21, the transverse portion 22 and the bottom cover 4 forms a stable connection structure, which can provide a stable support for the liquid heater, thereby maintaining the integrity and stability of the kettle body 1.

[0045] The kettle body 2 can be made of glass, which is beautiful and easy to clean.

[0046] In this embodiment, the kettle body 1 further comprises a handle 7 arranged outside the kettle body 2, the top of the handle 7 is fixed to the top outside of the kettle body 2 by a metal tie 71, and the bottom of the handle 7 is fixedly connected to the bottom cover 4. The top of the kettle body 2 is provided with a spout 23, the top of the kettle body 2 is provided with a lid 8, the bottom of the lid 8 is provided with a retaining ring 81 which extends into the top of the kettle body 2 and fits, the retaining ring 81 is provided with a plurality of water outlet holes 82, the bottom of the retaining ring 81 is lower than the spout 23 to prevent materials (such as tea leaves) from pouring out from the gap between the retaining ring 81 and the spout 23. The retaining ring 81 is provided with a plurality of springs 83 which fit closely with the kettle body 2 to increase the resistance of removing the lid 8 from the kettle body.

[0047] In this embodiment, a heat conducting plate 5 is further provided on the lower surface of the main body of the heating base 3, and the heating tube is fixed on the lower surface of the heat conducting plate 5. The material of the heating base 3 is generally stainless steel, which is easy to clean. The material of the heat conducting plate 5 is generally aluminum, which has good thermal conductivity and can transfer the heat of the heating tube to the heating base 3 more quickly and evenly, so that the liquid heater can heat up quickly and achieve a good liquid heating effect.
