Description

Technical Field

[0001] The utility model belongs to the technical field of liquid heating devices, and in particular relates to an air-insulated and overflow-proof liquid heater. Background Art

[0002] Existing liquid heating devices, such as soymilk machines, usually need to install an anti-overflow detection structure to prevent the slurry from overflowing after boiling. There are two main existing anti-overflow detection methods: one is contact anti-overflow electrode detection, in which the boiling slurry overflows and contacts the anti-overflow electrode, and the potential of the anti-overflow electrode is changed to achieve anti-overflow detection. When this detection method is used in a liquid heater, the anti-overflow electrode must be set in a place where the slurry can reach the glass cup body, which is easy to adhere to the slurry and bring inconvenience to cleaning; another anti-overflow detection method is remote detection, which is achieved by setting a detection board on the outside of the insulating glass cup body, and the detection board is attached to the capacitor electrode. The capacitance of the detection board changes with the volume of the liquid in the glass cup body, and the remote liquid level detection or anti-overflow detection is achieved without contact with the liquid, which is convenient for cleaning and has a high degree of intelligence.

[0003] For example, a patent application with application number 201720526032.4 discloses a food processor with good anti-overflow effect, including a base with a built-in motor and a mixing cup arranged above the base, the mixing cup includes a glass cup with a handle and a water level detection structure arranged on the outer side of the glass cup, the water level detection structure includes a detection component fitted on the outer wall of the glass cup and a capacitive sensing plate connected to the detection component, a handle shell is mounted on the handle, the handle shell includes an arc-shaped cavity matching the handle and an installation groove for embedding the capacitive sensing plate, and the capacitive sensing plate is positioned at a preset workstation adjacent to the outer wall of the glass cup through the handle shell.

[0004] In the above technology, since the outer wall of the glass is a cylindrical shape with an arc, and the induction plate is a strip-shaped flat plate, the induction plate is directly positioned on the smooth glass through the handle shell, which will cause the induction plate to be difficult to position and slide relative to the glass body, making the installation of the induction plate inconvenient and the assembly position inaccurate, affecting the detection accuracy. In addition, since the inner side of the glass is provided with a spoiler rib, when the preset position of the induction plate is facing the outer side of the spoiler rib, the wall thickness of the glass will be thickened due to the spoiler rib, affecting the detection accuracy of the induction plate. Utility Model Content

[0005] The utility model provides an air-insulated and spill-proof liquid heater to solve the problems in the prior art of difficulty in positioning a detection plate, resulting in difficulty in assembling the detection plate and inaccurate detection.

[0006] The technical solution adopted by the utility model is:

[0007] The utility model provides an air-insulated and overflow-proof liquid heater, comprising a glass cup body and a detection plate arranged on the outer side of the glass cup body for detecting the liquid level in the air, the detection plate is in a strip shape, the side wall of the glass cup body is provided with an inwardly protruding spoiler rib, the spoiler rib extends vertically, the outer side of the spoiler rib is recessed to form a mounting groove, and the detection plate is vertically mounted in the mounting groove.

[0008] The utility model provides an air-insulated anti-overflow liquid heater, comprising a glass cup body and a detection plate, wherein the side wall of the glass cup body has an inwardly protruding spoiler rib, and the spoiler rib extends vertically. When applied to a stirring operation scene, the spoiler rib has a spoiler effect on the liquid in the cup body, thereby improving the liquid processing effect, for example, improving the soybean milk crushing effect and the crushing efficiency in the process of preparing soybean milk. While utilizing the spoiler rib to achieve the spoiler effect, by providing an installation groove, the detection plate is vertically installed in the installation groove. On the one hand, compared with the method of directly installing the detection plate on the outer wall of the glass cup body, utilizing the installation groove to provide an installation space for the detection plate is conducive to pre-positioning the detection plate, facilitating further fixing of the detection plate, and reducing the difficulty of assembly; on the other hand, the installation groove avoids the increase of the wall thickness at the position of the spoiler rib, thereby avoiding the influence of the wall thickness of the glass cup body on the detection plate when the detection plate and the spoiler rib are in the corresponding position, thereby realizing effective air-insulated detection of the detection plate and improving the detection accuracy. Therefore, the glass cup body provided by the utility model can achieve a certain spoiler effect by utilizing spoiler ribs, and at the same time utilizes the installation groove to realize rapid assembly and accurate detection of the detection plate. The detection plate is vertically installed in the installation groove in a strip shape, so that multiple capacitor electrodes are arranged at intervals on the detection plate to realize comprehensive detection of low water level, high water level and overflow prevention, etc., with reliable detection and a wide range of applications.

[0009] In a preferred embodiment, a positioning plane is provided in the installation groove, and the detection plate includes a detection surface provided with a detection element, and the detection surface is in contact with the positioning plane.

[0010] By setting a positioning plane in the installation groove, the detection surface of the detection board is fitted to the positioning plane, and the positioning plane is used to further realize the positioning of the detection board, which facilitates the subsequent fixing operation of the detection board and reduces the difficulty of assembly. Moreover, the positioning plane and the detection surface of the detection board are fitted together, which is beneficial for the detection element on the detection board to effectively detect the capacitive signal, and the detection is sensitive and accurate.

[0011] In a preferred embodiment, a step surface is provided on the groove wall of the installation groove, and the step surface forms the positioning plane.

[0012] By arranging a step surface on the groove wall of the installation groove, the step surface forms a positioning plane to position the detection surface of the detection plate, and at the same time, the sunken transition surface of the step surface is used to limit the end of the detection plate, thereby realizing multi-directional positioning of the detection plate, and limiting the detection plate along the circumference of the glass cup body to avoid the deviation of the detection plate, thereby further improving the position accuracy of the detection plate, improving the accuracy of detection, and avoiding misjudgment.

[0013] In a preferred embodiment, the mounting groove includes a first side wall, a second side wall and a groove bottom wall connected between the first side wall and the second side wall, the groove bottom wall forms a positioning plane, and the detection surface of the detection plate is attached to the groove bottom wall.

[0014] The mounting groove includes a first side wall, a second side wall and a groove bottom wall. The groove bottom wall is a positioning plane. The detection surface of the detection board is directly attached to the groove bottom wall, thereby realizing direct positioning of the detection board, facilitating subsequent fixing operations on the detection board, reducing assembly difficulty, and facilitating the detection elements on the detection board to effectively detect capacitance signals, and the detection is sensitive and accurate.

[0015] In a preferred embodiment, the spoiler rib is provided with an inner plane corresponding to the position of the positioning plane.

[0016] By setting an inner plane corresponding to the position of the positioning plane on the spoiler rib, the inner plane and the positioning plane correspond to each other, so that the detection element on the detection board can effectively detect the liquid level inside the glass cup body, and the distance between the detection plate and the liquid is more uniform, thereby improving the consistency between the detection element on the detection board and the liquid signal sensing, making the detection more sensitive and accurate, and avoiding misjudgment and insensitive triggering.

[0017] In a preferred embodiment, the horizontal cross-section of the mounting groove is V-shaped, and the mounting groove includes two connected groove walls, and the detection plate is arranged toward one of the groove walls.

[0018] Taking into account the spoiler effect of the spoiler ribs and the noise during the spoiler process, the spoiler ribs of the glass cup body generally protrude inward in a V shape. Therefore, the horizontal cross-section of the mounting groove is V-shaped, which is easy to form. When the horizontal cross-section of the mounting groove is V-shaped and has two groove walls, the detection surface of the detection plate is set toward one of the groove walls, which is beneficial to the fitting positioning of the detection plate and the groove wall and reduces the difficulty of assembly. At the same time, it is beneficial to improve the consistency of the distance between the detection element of the detection plate and the liquid in the glass cup body, thereby improving the accuracy of detection.

[0019] In a preferred embodiment, the width of the mounting groove is W, satisfying 10 mm ≤ W ≤ 35 mm.

[0020] If the width of the installation slot is too large, greater than 35mm, the spoiler ribs may bulge inward too much, which may cause liquid splashing during operations such as crushing, resulting in overflow risks. If the width of the installation slot is too small, less than 10mm, it may make the detection board difficult to install, or it may be difficult for the detection elements on the detection board to sense signals, affecting the detection accuracy of the detection board. Therefore, meeting 10mm≤W≤35mm can reduce the risk of overflow while achieving accurate detection and reliable installation of the detection board.

[0021] In a preferred embodiment, the detection board is packaged in the installation groove through a glue potting layer.

[0022] The detection plate is sealed by filling the flowing colloid in the detection plate and the mounting groove, so that the detection plate is encapsulated in the mounting groove through the glue filling layer to form a whole with the glass cup body. The fixation between the detection plate and the glass cup body is in place in one step, eliminating the cumbersome assembly steps and assembly errors caused by indirect fixation through the handle, greatly simplifying the assembly method, and while the detection plate is fixed by the glue filling layer, the outer side of the detection plate is effectively sealed, which is also beneficial to sealing the gap between the detection plate and the mounting groove to prevent water vapor from entering. The seal is reliable and the operation of separately setting up a sealing film is eliminated. While simplifying the assembly, the waterproofness of the detection plate is ensured to avoid the detection plate from failing due to water ingress and inaccurate detection, thereby improving the detection accuracy and reliability, extending the service life, and simplifying the assembly and sealing methods.

[0023] In a preferred embodiment, the detection board is provided with a glue inlet hole.

[0024] By setting glue inlet holes on the detection board, when the detection board and the groove wall of the installation groove cannot fit together, the flowing colloid fills the gap between the detection board and the installation groove through the glue inlet holes, thereby further avoiding the presence of water vapor in the gap and affecting the detection accuracy of the detection board, thereby improving the detection accuracy and reliability.

[0025] In a preferred embodiment, the liquid heater further comprises a mounting member fixed to the outside of the glass body, and the mounting member presses the detection plate into the mounting groove.

[0026] By providing a mounting piece and utilizing the fixed connection between the mounting piece and the glass cup body, the detection plate is pressed and held in the mounting groove, thereby achieving a reliable connection between the detection plate and the glass cup body.

[0027] In a preferred embodiment, a silicone pad is sandwiched between the detection board and the mounting groove, and a sealing cavity for sealing and wrapping the detection board is provided between the silicone pad and the mounting member;

[0028] By arranging a silicone pad, and arranging a sealing cavity between the silicone pad and the mounting member to seal and wrap the detection board, a closed detection environment is provided for the detection board to prevent water vapor and the like from affecting the detection of the detection board.

[0029] In a preferred embodiment, the mounting member is a handle.

[0030] The mounting piece is a handle, which not only achieves reliable fixation of the detection board, but also makes it convenient for users to take the cup body. The handle integrates multiple functions to achieve a compact structure. 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.

[0049] like Figure 1-5 As shown, the utility model provides an air-insulated and spill-proof liquid heater in one embodiment, comprising a glass cup body 10 and a detection plate 20 arranged on the outside of the glass cup body 10 for detecting the liquid level in the air, the detection plate 20 is strip-shaped, and the side wall of the glass cup body 10 has an inwardly protruding spoiler rib 30, the spoiler rib 30 extends vertically, and the outer side of the spoiler rib 30 is recessed to form a mounting groove 40, and the detection plate 20 is vertically installed in the mounting groove 40.

[0050] For example, a mounting wall 11 with a convex interior and a concave exterior is provided on the side wall of the glass body, a spoiler rib 30 is formed on the inner side of the mounting wall 11 , and a mounting groove 40 is formed on the outer side.

[0051] Specifically, Figure 3 As shown, a mounting groove 40 is formed on the outer side of the mounting wall 11 , and the detection board 20 is vertically mounted in the mounting groove 40 .

[0052] In this embodiment, the liquid heater is a soymilk machine, a crushing blade 12 is provided inside the glass cup body 10, and a motor 13 and a heating plate 14 are provided at the bottom of the glass cup body 10 to drive the crushing blade 12 to rotate, so as to prepare soymilk. The glass cup body 10 can be a stretched glass cup body 10 or a die-cast glass cup body 10.

[0053] The air-insulated and overflow-proof liquid heater provided in this embodiment includes a glass cup body 10 and a detection plate 20. The side wall of the glass cup body 10 has spoiler ribs protruding inward, and the spoiler ribs extend vertically and form spoiler ribs 30 on the inner side. When used in a stirring operation scenario, the spoiler ribs 30 have a spoiler effect on the liquid in the cup body, thereby improving the liquid processing effect. For example, in the process of preparing soy milk, the soy milk crushing effect and the crushing efficiency are improved. While using the spoiler ribs to achieve the spoiler effect, the detection plate 20 is vertically installed in the installation groove 40 by using the installation groove. On the one hand, compared with the method of directly installing the detection plate 20 on the outer wall of the glass cup body 10, the installation groove 40 is used to provide the installation space of the detection plate 20, which is conducive to the pre-positioning of the detection plate 20, and is convenient for further fixing the detection plate 20, reducing the difficulty of assembly; on the other hand, the installation groove 40 avoids the increase of the wall thickness at the position of the spoiler rib 30, so that when the positions of the detection plate 20 and the spoiler rib 30 correspond, the influence of the wall thickness of the glass cup body 10 on the detection plate 20 is avoided, and the detection plate 20 is effectively separated from the air, and the detection accuracy is improved. Therefore, the glass cup body 10 provided by the utility model can not only achieve a certain spoiler effect by using the spoiler ribs, but also realize the rapid assembly and accurate detection of the detection plate 20. The detection plate 20 is vertically installed in the installation groove 40 in a strip shape, so that multiple capacitor electrodes are arranged on the detection plate 20 at intervals, and comprehensive detection such as low water level, high water level and overflow prevention is realized, and the detection is reliable and has a wide range of applications.

[0054] The present invention does not limit the specific form of the installation wall 11, for example:

[0055] Implementation example 1, such as Figure 1-5 As shown, the inner side of the installation wall 11 protrudes inward in an arc shape together with the outer side, so that the side wall of the spoiler rib 30 and the groove wall of the installation groove 40 are both arc surfaces.

[0056] In this embodiment, the detection plate 20 is a rigid strip-shaped flat plate, preferably, Figure 3 As shown, the detection board 20 is encapsulated in the installation groove 40 through the glue layer 15. Figure 5 As shown, the test board 20 is provided with a glue feeding hole 201. Specifically, the test board 20 includes a substrate, a capacitor electrode installed on one side of the substrate, and the glue feeding hole is arranged through the substrate and staggered with the capacitor electrode.

[0057] Of course, the capacitor electrode can also be other detection elements such as a spring.

[0058] The detection plate 20 and the mounting groove are sealed by filling the flowing colloid in the detection plate 20, so that the detection plate 20 is encapsulated in the mounting groove through the glue filling layer to form a whole with the glass cup body 10. The fixation between the detection plate 20 and the glass cup body 10 is in place in one step, eliminating the cumbersome assembly steps and assembly errors caused by indirect fixation through the handle, greatly simplifying the assembly method, and while the detection plate 20 is fixed by the glue filling layer, the outer side of the detection plate 20 is effectively sealed, which is also beneficial to sealing the gap between the detection plate 20 and the mounting groove 40 to prevent water vapor from entering, and the sealing is reliable, eliminating the need for separate setting of sealing film and other operations, while simplifying the assembly, it also ensures the waterproofness of the detection plate 20, avoids the detection plate 20 from failing due to water ingress and inaccurate detection, improves detection accuracy and reliability, extends service life, and simplifies assembly and sealing methods. By setting glue inlet holes on the detection board 20, when the detection board 20 and the groove wall of the installation groove 40 cannot fit together, the flowing colloid fills the gap between the detection board 20 and the installation groove 40 through the glue inlet holes, thereby further avoiding the presence of water vapor in the gap and affecting the detection accuracy of the detection board 20, thereby improving the detection accuracy and reliability.

[0059] Of course, the detection board 20 can also be a flexible board or a curved board to adapt to the groove wall of the installation groove 40 for fitting installation.

[0060] Implementation Example 2, such as Figure 6 As shown, a positioning plane is provided in the installation groove 40, and the detection plate 20 includes a detection surface provided with a detection element, and the detection surface is in contact with the positioning plane. Specifically, a step surface 401 is provided on the groove wall of the installation groove 40, and the step surface 401 forms the positioning plane.

[0061] By setting a positioning plane in the installation groove 40, the detection surface of the detection plate 20 is fitted to the positioning plane, and the positioning plane is used to further realize the positioning of the detection plate 20, which is convenient for the subsequent fixing operation of the detection plate 20 and reduces the difficulty of assembly. Moreover, the positioning plane and the detection surface of the detection plate 20 are fitted together, which is conducive to the detection element on the detection plate 20 to effectively detect the capacitive signal, and the detection is sensitive and accurate. By setting a step surface 401 on the groove wall of the installation groove 40, the step surface 401 forms a positioning plane to position the detection surface of the detection plate 20, and at the same time, the end of the detection plate 20 is limited by the sinking transition surface of the step surface 401, so as to realize the multi-directional positioning of the detection plate 20, limit the detection plate 20 along the circumference of the glass cup body 10, avoid the deviation of the detection plate 20, further improve the position accuracy of the detection plate 20, improve the accuracy of detection, and avoid misjudgment.

[0062] Of course, in addition to the irregular shape in this embodiment, the mounting groove can also be selected to be V-shaped or U-shaped in horizontal cross-section, and the positioning plane can also be provided with an outwardly protruding boss at the bottom of the mounting groove 40 to form a positioning plane using the boss.

[0063] Implementation Example 3, such as Figure 7 , Figure 8 , Fig. 9 As shown, the mounting groove 40 includes a first side wall 41, a second side wall 42, and a groove bottom wall 43 connected between the first side wall and the second side wall. Fig. 9 As shown, the groove bottom wall 43 forms a positioning plane, and the detection surface of the detection plate 20 is attached to the groove bottom wall 43.

[0064] In this embodiment, if Figure 7 As shown, the liquid heater is a food processor that does not require hand washing, including a main unit 70 and a cup body assembly. The cup body assembly is detachably installed in the main unit 70 , and the cup body assembly includes a glass cup body 10 .

[0065] In this implementation example, Fig. 9 As shown, preferably, the spoiler rib 30 is provided with an inner plane 301 corresponding to the position of the positioning plane.

[0066] Of course, the setting of the inner plane is not limited to the present embodiment. It can be understood that when a positioning plane is provided in the installation groove and the detection surface of the detection plate is in contact with the positioning plane, an inner plane 301 corresponding to the position of the positioning plane can be provided on the spoiler rib.

[0067] By setting an inner plane 301 corresponding to the position of the positioning plane on the spoiler rib 30, the inner plane 301 corresponds to the positioning plane, so that the detection element on the detection plate 20 can effectively detect the liquid level inside the glass cup body 10, and the distance between the detection plate 20 and the liquid is more uniform, thereby improving the consistency between the detection element on the detection plate 20 and the liquid signal sensing, making the detection more sensitive and accurate, and avoiding misjudgment and insensitive triggering.

[0068] Of course, in other preferred implementations of this embodiment, the spoiler rib 30 is a V-shaped or arc-shaped structure in horizontal cross section, and only a positioning plane is formed on the bottom wall of the installation groove.

[0069] The mounting groove 40 includes a first side wall, a second side wall and a groove bottom wall. The groove bottom wall is a positioning plane. The detection surface of the detection board 20 is directly attached to the groove bottom wall, thereby realizing direct positioning of the detection board 20, facilitating subsequent fixing operations on the detection board 20, reducing assembly difficulty, and facilitating the detection elements on the detection board 20 to effectively detect capacitance signals, and the detection is sensitive and accurate.

[0070] In implementation example 4, the horizontal cross section of the mounting groove 40 is V-shaped, and the mounting groove 40 includes two connected groove walls, and the detection plate 20 is disposed toward one of the groove walls.

[0071] In this embodiment, the spoiler rib 30 may be in a V-shape that follows the groove wall of the mounting groove 40 , or may be in other shapes.

[0072] More preferably, one of the groove walls of the mounting groove is a plane to form a positioning plane.

[0073] Taking into account the spoiler effect of the spoiler rib 30 and the noise during the spoiler process, the spoiler rib of the glass cup body 10 generally protrudes inward in a V shape. Therefore, the horizontal cross-section of the mounting groove 40 is V-shaped, which is easy to form. When the mounting groove 40 has a V-shaped horizontal cross-section and has two groove walls, the detection surface of the detection plate 20 is set toward one of the groove walls, which is beneficial to the fitting positioning of the detection plate 20 and the groove wall, reduces the difficulty of assembly, and is also beneficial to improving the consistency of the distance between the detection element of the detection plate 20 and the liquid in the glass cup body 10, thereby improving the accuracy of detection.

[0074] In a preferred embodiment, the width of the mounting groove is W, satisfying 10 mm ≤ W ≤ 35 mm.

[0075] If the width of the installation slot is too large, greater than 35mm, the spoiler ribs may bulge inward too much, which may cause liquid splashing during operations such as crushing, resulting in overflow risks. If the width of the installation slot is too small, less than 10mm, it may make the detection board difficult to install, or it may be difficult for the detection elements on the detection board to sense signals, affecting the detection accuracy of the detection board. Therefore, meeting 10mm≤W≤35mm can reduce the risk of overflow while achieving accurate detection and reliable installation of the detection board.

[0076] More preferably, 12mm≤W≤20mm to further reduce the risk of overflow and improve the detection accuracy of the detection board.

[0077] It should be noted that the fixing of the detection board 20 in the present invention is not limited to the glue filling method. In fact, the fixing of the detection board 20 can also be:

[0078] Implementation Example 5, such as Fig.10 As shown, the liquid heater further includes a mounting member 50 fixed to the outside of the glass body 10 , and the mounting member 50 presses the detection plate 20 into the mounting groove 40 .

[0079] By providing the mounting member 50 and utilizing the fixed connection between the mounting member 50 and the glass body 10 , the detection board 20 is pressed and held in the mounting groove 40 , thereby achieving a reliable connection between the detection board 20 and the glass body 10 .

[0080] As a preferred implementation of this embodiment, a silicone pad 60 is sandwiched between the detection board 20 and the mounting groove 40 to enable the detection board 20 and the mounting groove 40 to be flexibly pressed.

[0081] Of course, the mounting member 50 may also be provided with a spring, and the spring abuts against the outer side surface of the detection plate 20 to achieve reliable pressing of the detection plate 20 .

[0082] More preferably, a sealed cavity is provided between the silicone pad 60 and the mounting member 50 to seal and wrap the detection board 20. For example, the silicone pad 60 includes a first silicone sheet 61 and a second silicone sheet 62 clamped on both sides of the detection board 20, and the first silicone sheet 61 and the second silicone sheet 62 enclose to form a sealed cavity.

[0083] Alternatively, in other embodiments, the silicone pad 60 is provided with a recessed groove for accommodating the detection plate 20, and the mounting member 50 includes a covering member for covering the recessed groove, and the covering member and the recessed groove are combined to form a sealed cavity.

[0084] By providing a silicone pad 60 and providing a sealed cavity between the silicone pad 60 and the mounting member 50 to seal and wrap the detection board 20 , a closed detection environment is provided for the detection board 20 to prevent water vapor and the like from affecting the detection of the detection board 20 .

[0085] As a preferred implementation of this example, Fig.10 As shown, the liquid heater is a soybean milk maker, and the mounting member 50 is a handle.

[0086] The mounting member 50 is a handle, which can not only achieve reliable fixation of the detection board 20, but also facilitate the user to take the cup body. Therefore, the handle integrates multiple functions to achieve a compact structure.

[0087] It should be noted that the liquid heater provided by the utility model can be not only the above-mentioned soybean milk machine and the food processor without hand washing, but also a wall breaking machine, a water kettle, a health pot, etc. In addition, the mounting member 50 can be a panel, a decorative member (such as Figure 7 shown) etc.
