Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a liquid heater. Background Art

[0002] The anti-overflow detection methods currently used in kitchen appliances include contact and non-contact types. For example, the Chinese patent application number 201720526032.4 previously filed by the present applicant discloses a non-contact anti-overflow detection method, in which a detection component is fitted on the outer wall of a glass, and the handle shell is used to position and shield the detection component at a preset position adjacent to the outer wall of the glass. Although in this solution, the capacitive sensing plate and the glass body are in a relatively fixed relationship and no displacement occurs between the two, and the fixed structure is reliable, in this structure, a handle is required on the glass body to position the handle shell, and then the capacitive sensing plate is fixed and limited by the positioning of the handle shell. Not only is the installation structure complex and the installation steps cumbersome, but the assembly errors between the various parts accumulate, resulting in inaccurate assembly position of the sensing plate and inaccurate detection.

[0003] The applicant has previously filed an application with application number CN2024103319154, in which the detection plate is positioned on the outer wall of the glass cup body with the help of a positioning plate, and a receiving cavity for accommodating the detection plate is formed by the positioning plate and the peripheral wall of the glass cup body. The detection plate is first positioned in the receiving cavity, and then glue is poured into the receiving cavity. After the glue solidifies, the detection plate is reliably positioned in the receiving cavity, which simplifies the positioning structure of the detection plate and reduces assembly errors. However, if the glue is simply used to bond the detection plate to the outer wall of the glass cup body, since the glass cup body will be heated when it is in working condition, the glue layer will soften due to long-term heat, the viscosity will deteriorate, and the fixing effect will not last long, which will cause the adhesion between the detection plate and the glass cup body to deteriorate, and the detection plate will separate from the glass cup body. Utility Model Content

[0004] The utility model provides a liquid heater, which positions the detection plate on the glass cup body by designing an installation structure, thereby solving the problem of complicated installation steps of the detection plate and the problem of poor durability of the fixing effect between the detection plate and the glass cup body in a long-term heating environment.

[0005] The technical solution adopted by this utility model is:

[0006] The utility model provides a liquid heater, comprising a glass cup body and a detection plate for detecting the liquid level in the air, the detection plate being strip-shaped and vertically arranged on the outside of the glass cup body, the liquid heater also comprising a mounting bracket fixed to the outside of the glass cup body, the mounting bracket being provided with a plurality of elastically deformable spring clips, the plurality of spring clips being arranged around the edge of the detection plate, at least two of the spring clips being respectively located on opposite sides of the detection plate, the plurality of spring clips cooperating to position the detection plate on the outside of the glass cup body.

[0007] The utility model provides a liquid heater, by arranging a mounting bracket on the outside of the glass cup body, and a plurality of elastically deformable spring buckles are provided on the mounting bracket, and the elastic deformation characteristics of the spring buckles are utilized, and the plurality of spring buckles are arranged around the edge of the detection plate. During the installation of the detection plate, the edge of the detection plate squeezes the spring buckles to cause them to deform. After the detection plate is installed to the preset position, the detection plate is limited by the spring buckles, which is simple and fast to operate, saves time and labor, and improves assembly efficiency. The plurality of spring buckles cooperate to position the detection plate on the outside of the glass cup body, and the detection plate is positioned by the spring buckles to achieve mechanical fixation, which reduces the need for the glass cup body to be fixed. The impact of long-term exposure to a heating environment on the fixing reliability of the detection plate makes the fixation of the detection plate reliable and durable, and effectively prevents the detection plate from falling off or loosening. Since at least two of the spring buckles are located on opposite sides of the detection plate, the forces on both sides of the detection plate are balanced, avoiding one side of the detection plate from tilting or the detection plate from being skewed, which is beneficial to the accurate detection of the detection plate. In addition, the use of the spring buckle to position the detection plate reduces the accumulation of assembly errors compared to the traditional technology of positioning the detection plate with multiple assembly parts of the handle and the handle shell, which is beneficial to the accurate positioning of the detection plate and improves the detection accuracy of the detection plate.

[0008] In a preferred embodiment, the spring clip includes a connecting portion and a deformation portion connected to the mounting bracket, the free end of the deformation portion forms a snap fit with the outer side surface of the glass cup body, the detection plate squeezes the deformation portion to fit into the snap fit, and the free end of the deformation portion abuts against the outer side surface of the detection plate after resetting.

[0009] The snap fastener includes a connecting part and a deformation part, and the free end of the deformation part is used to form a bayonet with the outer side surface of the glass cup body for the detection plate to be installed. After the detection plate squeezes the deformation part, the deformation part elastically moves to be installed into the bayonet. In the process of the detection plate squeezing the deformation part, the deformation part also guides the detection plate, so that the detection plate is accurately installed to the preset position along the deformation part. The position of the detection plate is accurately installed, and the free end of the deformation part abuts against the outer side surface of the detection plate after resetting, and the free end of the deformation part is used to directly prevent the detection plate from detaching from the glass cup body outward, so that the connection between the detection plate and the glass cup body is reliable.

[0010] In a preferred embodiment, the detection plate has a long side extending vertically and a short side extending laterally, the spring buckles are arranged in pairs on both sides of the long side, and the outer side of the glass cup body is also provided with a pair of retaining edges on both sides of the short side.

[0011] By arranging the snap hooks in pairs on both sides of the long side, the snap hooks position the detection plate in the horizontal direction, preventing the detection plate from detaching from the glass cup body. At the same time, a rib is arranged on the outside of the glass cup body to position the detection plate vertically, preventing the detection plate from falling downward, so that the detection plate can be reliably positioned in different directions, thereby strengthening the reliable connection between the detection plate and the glass cup body.

[0012] In a preferred embodiment, the spring buckle is provided on each side of the detection plate.

[0013] By setting spring buckles on each side of the detection plate, reliable limiting is achieved in different directions of the detection plate, so that the detection plate is subjected to balanced force, avoiding deviation and loosening of the detection plate and preventing the detection plate from detaching from the glass cup body.

[0014] In a preferred embodiment, the spring clip includes a connecting portion and a deformation portion connected to the mounting bracket, the free end of the deformation portion extends toward the outer surface of the side wall of the glass cup body, the detection plate abuts against the outer surface of the side wall of the glass cup body, and the deformation portion of the spring clip clamps the detection plate.

[0015] The detection plate is clamped by the deformation part of the spring buckle, which can facilitate the assembly of the detection plate. The worker only needs to press the detection plate to the preset position to complete the positioning of the detection plate. The operation is labor-saving and convenient, and it is also convenient for the disassembly and assembly of the detection plate and the replacement of the detection plate. In addition, the detection plate can be positioned horizontally under the clamping force of the spring buckle to prevent the detection plate from being offset, and can also be positioned vertically to prevent the detection plate from falling downward, so that the detection plate can be reliably fixed on the outside of the glass cup body.

[0016] In a preferred embodiment, the plurality of snap buckles include a first snap buckle and a second snap buckle arranged in pairs, and the first snap buckle and the second snap buckle are symmetrically arranged on both sides of the detection plate;

[0017] By arranging the first spring buckle and the second spring buckle symmetrically on both sides of the detection plate, that is, arranging the spring buckles in pairs, the force on the detection plate is balanced, the detection plate is prevented from moving, the fixation is reliable, and the appearance is beautiful.

[0018] In a preferred embodiment, the plurality of snap hooks include a first snap hook, a second snap hook and a third snap hook, wherein the first snap hook and the second snap hook are located on the same side of the detection plate, and the third snap hook is located on the other side of the detection plate and is staggered between the first snap hook and the second snap hook.

[0019] By providing the first spring buckle, the second spring buckle and the third spring buckle, the three spring buckles are distributed on both sides of the detection plate, thereby achieving reliable positioning of both sides of the detection plate. At the same time, the third spring buckle is staggered between the first spring buckle and the second spring buckle, forming a staggered arrangement, which saves the number of spring buckles while ensuring reliable fixation of the detection plate.

[0020] In a preferred embodiment, the mounting bracket includes a first bracket and a second bracket which are separately provided, and both the first bracket and the second bracket are provided with the spring buckle.

[0021] The mounting bracket includes a first bracket and a second bracket that are separately arranged. Therefore, the shape design of the first bracket and the second bracket can be more flexible. In addition, since some liquid heaters have some components naturally arranged on the outside of the glass cup body due to functional requirements, such as a decorative ring that is sleeved on the outside of the glass cup body or a cup holder fixed on the lower side of the glass cup body, the mounting bracket can utilize the liquid heater's own structure as the first bracket or the second bracket by setting the first bracket and the second bracket separately, thereby realizing structural integration and simplification.

[0022] More preferably, the first bracket and the second bracket are located on opposite sides of the detection board;

[0023] Alternatively, the first bracket is a decorative ring that is sleeved and fixed on the outside of the glass body;

[0024] Alternatively, the second bracket is a cup holder that is sleeved and fixed on the outside of the glass body.

[0025] By arranging the first bracket and the second bracket on opposite sides of the detection plate, it is convenient to directly arrange spring buckles on the first bracket and the second bracket to achieve positioning of the opposite sides of the detection plate, reduce the arrangement of spring buckles, and have a compact structure.

[0026] By setting the first bracket as a decorative ring that is sleeved and fixed on the outside of the glass cup body; and setting the second bracket as a cup holder that is sleeved and fixed on the outside of the glass cup body, the first bracket and the second bracket are not only used to form the spring buckle installation position, but also serve as a decorative ring to realize functions such as decoration or assembly handles, and as a cup holder to realize support and other functions, thereby realizing functional integration and making the structure of the whole machine compact.

[0027] In a preferred embodiment, the mounting bracket includes an annular rib, the spring clip is provided on the rib, the rib encloses to form a positioning groove for accommodating the detection board, and glue is poured into the positioning groove to encapsulate the detection board.

[0028] The mounting bracket forms a positioning groove through the surrounding reinforcement, and the spring buckle is set on the surrounding reinforcement to perform primary positioning of the detection plate. By pouring glue into the positioning groove, the detection plate is positioned secondary using the glue, making the connection between the detection plate and the glass cup body more reliable, preventing the detection plate from falling or shifting and causing detection failure.

[0029] In a preferred embodiment, the snap fastener is detachably fixed to the mounting bracket;

[0030] Alternatively, the snap button includes a spring or a spring.

[0031] By removably fixing the spring clips to the mounting bracket, for example, using springs or spring clips, the number of spring clips can be flexibly and reasonably arranged according to the size of the detection board. The spring clips are flexible to be disassembled and assembled. For small detection boards, the number of spring clips can be reduced to avoid unnecessary waste. For large detection boards, the number of spring clips can be increased, thereby achieving reliable fixation of different types of detection boards. BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0047] like Figure 1-5 As shown, the utility model provides a liquid heater in one embodiment, including a glass cup body 10 and a detection plate 20 for detecting the liquid level in the air, the detection plate 20 is strip-shaped and vertically arranged on the outside of the glass cup body 10, and the liquid heater also includes a mounting bracket 30 fixed on the outside of the glass cup body 10, and the mounting bracket 30 is provided with a plurality of elastically deformable spring clips 40, and the plurality of spring clips 40 are arranged around the edge of the detection plate 20, and at least two spring clips 40 are respectively located on two opposite sides of the detection plate 20, and the plurality of spring clips 40 cooperate to position the detection plate 20 on the outside of the glass cup body 10.

[0048] The utility model provides a liquid heater, which provides a mounting bracket 30 on the outer side of the glass cup body 10, and a plurality of elastically deformable spring buckles 40 are provided on the mounting bracket 30. The elastic deformation characteristics of the spring buckles 40 are utilized, and since the plurality of spring buckles 40 are arranged around the edge of the detection plate 20, the edge of the detection plate 20 squeezes the spring buckles 40 to deform it during the installation of the detection plate 20. After the detection plate 20 is installed to the preset position, the detection plate 20 is limited by the spring buckles 40, which is simple and fast to operate, saves time and labor, and improves assembly efficiency. The plurality of spring buckles 40 cooperate to position the detection plate 20 on the outer side of the glass cup body 10, and the detection plate 20 is positioned by the spring buckles 40 to achieve mechanical fixation, reducing The glass cup body 10 needs to be in a heated environment for a long time, which affects the fixing reliability of the detection plate 20, so that the fixing of the detection plate 20 is reliable and durable, and the detection plate 20 is effectively prevented from falling off or loosening. Since at least two spring buckles 40 are respectively located on opposite sides of the detection plate 20, the forces on both sides of the detection plate 20 are balanced, avoiding one side of the detection plate 20 from tilting or the detection plate 20 from being tilted, which is beneficial to the accurate detection of the detection plate 20. In addition, the detection plate 20 is positioned by the spring buckle 40, which reduces the accumulation of assembly errors compared to the traditional technology of positioning the detection plate 20 by multiple assembly parts of the handle and the handle shell, which is beneficial to the accurate positioning of the detection plate 20 and improves the detection accuracy of the detection plate 20.

[0049] Preferably, a capacitor electrode is provided on the side of the detection plate 20 facing the glass body to detect the liquid level in the glass body in the air. The capacitor electrode includes a water level capacitor electrode for detecting the water level and an anti-overflow capacitor electrode for preventing overflow, and the water level capacitor electrode is provided below the anti-overflow capacitor electrode.

[0050] It should be noted that the present invention does not limit the specific positioning method of the snap hook 40 on the detection plate 20. For example, it can adopt any of the following implementation examples:

[0051] Implementation Example 1, such as Figure 1-5 As shown, the snap fastener 40 includes a connecting portion 41 connected to the mounting bracket 30 and a deforming portion 42. Figure 4 As shown, the free end of the deformation portion 42 forms a bayonet 43 with the outer side of the glass body 10, and the detection plate 20 squeezes the deformation portion 42 to fit into the bayonet 43. When the detection plate 20 squeezes the deformation portion 42, the deformation direction of the deformation portion 42 is as shown in FIG. Figure 4 The direction of the arrow shown, as Figure 5 As shown, when the detection plate 20 is installed in the bayonet 43 , the free end of the deformable portion 42 abuts against the outer side surface of the detection plate 20 after being reset.

[0052] The snap hook 40 includes a connecting portion 41 and a deforming portion 42. The free end of the deforming portion 42 and the outer side surface of the glass cup body 10 form a snap-in 43 for the detection plate 20 to be installed. After the detection plate 20 squeezes the deforming portion 42, the deforming portion 42 elastically moves to be installed into the snap-in 43. In the process of the detection plate 20 squeezing the deforming portion 42, the deforming portion 42 also guides the detection plate 20, so that the detection plate 20 is accurately installed to the preset position along the deforming portion 42. The position of the detection plate 20 is accurately installed, and the free end of the deforming portion 42 abuts against the outer side surface of the detection plate 20 after resetting. The free end of the deforming portion 42 is used to directly prevent the detection plate 20 from detaching from the glass cup body 10 outward, so that the connection between the detection plate 20 and the glass cup body 10 is reliable.

[0053] Of course, it should be noted that the free end of the above-mentioned deformation part 42 abuts against the outer side surface of the detection plate 20, which can be selected as contact or pressure. Preferably, in this embodiment, the free end of the deformation part 42 provides a pressing force to press the detection plate 20, so that the detection plate 20 and the glass cup body 10 can be tightly attached, thereby improving the detection sensitivity of the detection plate 20.

[0054] More preferably, if Figure 2 、 3 As shown, the detection plate 20 has a long side extending vertically and a short side extending horizontally. The spring buckles 40 are arranged in pairs on both sides of the long side, that is, the left and right sides of the detection plate 20. The outer side of the glass cup body 10 is also provided with a pair of retaining edges 50 that stop on both sides of the short side. The retaining edges 50 stop on the upper and lower sides of the detection plate 20.

[0055] Of course, it should be noted that in this implementation example, Figure 2 、 3 As shown, the retaining edge 50 is integrally formed with the mounting bracket 30 , and the mounting bracket 30 is a one-piece component.

[0056] In fact, in other implementation examples, the rib 50 may also be a convex rib protruding from the glass cup body 10 .

[0057] In this embodiment, the spring buckles 40 are arranged in pairs on both sides of the long side, and the spring buckles 40 position the detection plate 20 in the horizontal direction, thereby preventing the detection plate 20 from detaching from the glass cup body 10. At the same time, a retaining edge 50 is provided on the outside of the glass cup body 10, and the retaining edge 50 positions the detection plate 20 vertically, thereby preventing the detection plate 20 from falling downward, so that different directions of the detection plate 20 can be reliably positioned, thereby strengthening the reliable connection between the detection plate 20 and the glass cup body 10.

[0058] Implementation Example 2. This implementation example is similar to Implementation Example 1 in that the spring clip 40 includes a connecting portion 41 and a deformation portion 42 connected to the mounting bracket 30. The free end of the deformation portion 42 forms a snap fit 43 with the outer side surface of the glass cup body 10. The detection plate 20 squeezes the deformation portion 42 to fit into the snap fit 43. When the detection plate 20 is fitted into the snap fit 43, the free end of the deformation portion 42 abuts against the outer side surface of the detection plate 20 after resetting.

[0059] Different from Implementation Example 1, a spring clip 40 is provided on each side of the detection plate 20, that is, spring clips 40 are provided not only on the left and right sides of the detection plate 20, but also on the upper and lower sides of the detection plate 20, so that the detection plate 20 can be reliably positioned in the bayonet 43.

[0060] By setting spring buckles 40 on each side of the detection plate 20, reliable limiting is achieved in different directions of the detection plate 20, so that the detection plate 20 is subjected to balanced force, avoiding displacement and loosening of the detection plate 20 and preventing the detection plate 20 from detaching from the glass cup body 10.

[0061] Implementation Example 3, such as Figure 6 As shown, the spring clip 40 of this embodiment includes a connecting portion 41 and a deformation portion 42 connected to the mounting bracket 30. This embodiment is different from embodiment 1 in that the free end of the deformation portion 42 extends toward the outer surface of the side wall of the glass cup body 10, the detection plate abuts against the outer surface of the side wall of the glass cup body, and the deformation portion 42 of the spring clip 40 clamps the detection plate.

[0062] The detection plate 20 is clamped by the deformation part 42 of the spring buckle 40, which can facilitate the assembly of the detection plate 20. The worker only needs to press the detection plate 20 to the preset position to complete the positioning of the detection plate 20. The operation is labor-saving and convenient. It also facilitates the disassembly and assembly of the detection plate 20 and the replacement of the detection plate 20. In addition, the detection plate 20 can be positioned horizontally under the clamping force of the spring buckle 40 to prevent the detection plate 20 from being offset, and can also be positioned vertically to prevent the detection plate 20 from falling downward, so that the detection plate 20 can be reliably fixed on the outside of the glass cup body 10.

[0063] It should be noted that the present invention does not limit the specific arrangement position and number of the spring buckles 40. For example, in Example 1, Figure 3 As shown, the plurality of spring buckles 40 include a first spring buckle 401 and a second spring buckle 402 arranged in pairs. The first spring buckle 401 and the second spring buckle 402 are symmetrically arranged on both sides of the detection plate 20, and three pairs are provided.

[0064] By arranging the first spring buckle 401 and the second spring buckle 402 symmetrically on both sides of the detection plate 20, that is, arranging the spring buckles 40 in pairs, the force on the detection plate 20 is balanced, preventing the detection plate 20 from moving, and the fixation is reliable and the appearance is beautiful.

[0065] In addition to the arrangement of embodiment 1, the snap button 40 may also adopt other embodiments, for example:

[0066] Implementation Example 4, such as Figure 7 As shown, multiple spring buckles 40 include a first spring buckle 401, a second spring buckle 402 and a third spring buckle 403. The first spring buckle 401 and the second spring buckle 402 are located on the same side of the detection plate 20, and the third spring buckle 403 is located on the other side of the detection plate 20 and the third spring buckle 403 is staggered between the first spring buckle 401 and the second spring buckle 402.

[0067] By providing the first spring buckle 401, the second spring buckle 402 and the third spring buckle 403, the three spring buckles 40 are distributed on both sides of the detection plate 20, thereby achieving reliable positioning of both sides of the detection plate 20. At the same time, the third spring buckle 403 is staggered between the first spring buckle 401 and the second spring buckle 402, forming a staggered arrangement. Under the premise of achieving reliable fixation of the detection plate 20, the number of spring buckles 40 arranged is saved.

[0068] In addition, the spring buckle 40 may be integrally formed with the mounting bracket 30 , or the spring buckle 40 may be detachably fixed to the mounting bracket 30 . For example, the spring buckle 40 may include a spring or a spring sheet detachably fixed to the mounting bracket 30 .

[0069] By removably fixing the spring clips 40 to the mounting bracket 30, for example, using springs or spring clips, the number of spring clips 40 can be flexibly and reasonably arranged according to the size of the detection board 20. The spring clips 40 are flexible to be assembled and disassembled. For small detection boards 20, the number of spring clips 40 can be reduced to avoid unnecessary waste. For large detection boards 20, the number of spring clips 40 can be increased, thereby achieving reliable fixation of different models of detection boards 20.

[0070] It should be noted that the present invention does not limit the specific structure of the mounting bracket 30. For example, in Example 1, the mounting bracket 30 includes an annular rib, the aforementioned retaining edge 50 is integrally formed in the rib, and the snap hook 40 is disposed in the rib. More preferably, the rib encloses a positioning groove for accommodating the detection board 20, and glue is poured into the positioning groove to form a glue layer to encapsulate the detection board 20. Optionally, the positioning bracket is provided with adhesive backing to bond to the glass cup body 10.

[0071] The mounting bracket 30 forms a positioning groove through the ribs, and the spring buckle 40 is set on the ribs to perform primary positioning of the detection plate 20. By pouring glue into the positioning groove, the detection plate 20 is secondarily positioned using the glue, making the connection between the detection plate 20 and the glass cup body 10 more reliable, preventing the detection plate 20 from falling or shifting to cause detection failure.

[0072] Of course, the present invention does not limit the order of the detection board 20 and the glue pouring. For example, optionally, in a specific embodiment, the detection board 20 is installed between the positioning grooves, a first glue pouring layer is laid in the positioning grooves, and then the detection board 20 is arranged on the outside of the first glue pouring layer, and finally glue is poured on the outside of the detection board 20 to form a second glue pouring layer to encapsulate the detection board in the positioning grooves.

[0073] Of course, you can also first set the detection plate in the positioning groove and then fill it with glue to form a first glue layer between the detection plate and the glass cup body, and form a second glue layer on the outside of the detection plate away from the glass cup body to achieve reliable fixation of the detection plate.

[0074] In addition to the structure of the mounting bracket 30 shown in Example 1, other examples may also be used, for example:

[0075] Implementation Example 5, such as Figure 8 As shown, the mounting bracket 30 includes a first bracket 31 and a second bracket 32 ​​which are separately provided. Both the first bracket 31 and the second bracket 32 ​​are provided with a spring buckle 40 .

[0076] The mounting bracket 30 includes a first bracket 31 and a second bracket 32 ​​that are separately arranged. Therefore, the shape design of the first bracket 31 and the second bracket 32 ​​can be more flexible. In addition, since in some liquid heaters, some components are naturally set on the outside of the glass cup body 10 due to functional requirements, such as a decorative ring that is sleeved on the outside of the glass cup body 10 or a cup base fixed on the lower side of the glass cup body 10, the mounting bracket 30 can utilize the liquid heater's own structure as the first bracket 31 or the second bracket 32 ​​by setting the separate first bracket 31 and the second bracket 32, thereby realizing structural integration and simplification.

[0077] More preferably, the first bracket 31 and the second bracket 32 ​​are located on opposite sides of the detection board 20 . For example, in this embodiment, the first bracket 31 and the second bracket 32 ​​are located on the upper and lower sides of the detection board 20 .

[0078] Specifically, in this implementation example, Figure 8 As shown, the first bracket 31 is a decorative ring that is sleeved and fixed on the outside of the glass cup body 10, and the decorative ring is optionally used to fix the handle; the second bracket 32 ​​is a cup base that is sleeved and fixed on the outside of the glass cup body 10.

[0079] By arranging the first bracket 31 and the second bracket 32 ​​on opposite sides of the detection board 20, it is convenient to directly arrange the spring buckle 40 on the first bracket 31 and the second bracket 32 ​​to achieve positioning of the opposite sides of the detection board 20, reduce the arrangement of the spring buckle 40, and make the structure compact.

[0080] By setting the first bracket 31 as a decorative ring that is sleeved and fixed on the outside of the glass cup body 10; and setting the second bracket 32 ​​as a cup holder that is sleeved and fixed on the outside of the glass cup body 10, the first bracket 31 and the second bracket 32 ​​are not only used to form the installation position of the spring buckle 40, but also serve as a decorative ring to realize functions such as decoration or assembly handles, and as a cup holder to realize support and other functions, thereby realizing functional integration and making the structure of the whole machine compact.

[0081] The present invention does not limit the structure of the liquid heater. For example, the liquid heater can be selected as a food processor, and a crushing knife is provided inside the glass cup body 10 to realize the function of crushing soy milk and juice; or, the liquid heater can be selected as a boiling water kettle; of course, the liquid heater can also be selected as a health pot, etc.

[0082] Anything not described in this utility model can be achieved by adopting or drawing on existing technologies.

[0083] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0084] The above are merely examples of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
