Description

Technical Field

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

[0002] With the advancement of technology, the anti-overflow detection method currently used in kitchen appliances is mainly a remote detection plate detection. The detection plate is arranged on the outer wall of the glass cup body. The detection plate is provided with a capacitor electrode for remote sensing the liquid level in the cup body and a processing chip electrically connected to the capacitor electrode to achieve anti-overflow detection. For example, the Chinese patent application number 201720526032.4 previously filed by the applicant discloses a food processing machine with good anti-overflow effect. The detection component is fitted on the outer wall of the glass cup, and the handle shell of the handle is used to position and shield the detection component at a preset station adjacent to the outer wall of the glass cup, so as to achieve hidden installation of the detection component.

[0003] Due to the complexity of installing the detection plate in the prior art, there are few technologies that disclose installing a liquid level detection plate on a double-layer cup body. The applicant wants to solve the positioning problem of the detection plate in the double-layer cup body structure, and has previously proposed an application with application number 2023231778235. In this application, the liquid heater includes an outer shell, a cup body mounted in the outer shell, and a detection plate for detecting the liquid level in the cup body. The detection plate is located between the glass cup body and the outer shell. A push piece is fixedly installed on the outer side of the outer shell. The side wall of the outer shell is provided with an avoidance through hole for the push piece to push the detection plate. After the cup body is installed in the outer shell, the push piece pushes the detection plate to move radially until it abuts against the outer wall of the cup body. This solution can achieve close contact between the detection plate and the cup body without affecting the assembly of the cup body and the outer shell, and will not cause the position of the detection plate to move during the process of mounting the cup body, thereby improving the detection sensitivity and accuracy.

[0004] However, during the operation or cleaning of the liquid heater, steam or cleaning water may enter the interlayer between the cup body and the shell. In order to prevent the water vapor from affecting the detection plate, the detection plate is generally wrapped with silica gel in the prior art. The reliability of the matching between the silica gel and the detection plate is poor, resulting in unreliable sealing. When condensed water exists in the space between the detection plate and the glass cup body, it will affect the detection accuracy of the detection plate. The sealing and positioning steps of the detection plate are cumbersome, resulting in complicated assembly steps and inconvenient assembly. In addition, the positioning of the detection plate is completed after the cup body is installed by setting the push piece, which makes the structural matching complicated and the installation cost high. Utility Model Content

[0005] The utility model provides a liquid heater, which solves the problem in the prior art that when a detection plate is installed between two layers of a double-layer cup-type liquid heater, it is difficult to seal and position the detection plate in one step.

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

[0007] The utility model provides a liquid heater, comprising a glass cup body, a cup body shell sleeved on the outside of the glass cup body, and a strip-shaped detection plate for detecting the liquid level in the glass cup body in the air, the cup body shell is provided with a vertically extending through-opening and a surrounding edge extending from the edge of the through-opening toward the glass cup body, the surrounding edge is combined to form a positioning groove, the detection plate is positioned in the positioning groove, and the detection plate is encapsulated by pouring glue into the positioning groove.

[0008] The utility model provides a liquid heater, comprising a glass cup body and a cup body shell sleeved on the outside of the glass cup body, the cup body shell can play a heat insulation and noise reduction effect, avoid the problem of scalding, and reduce working noise. A vertically extending through-opening and a surrounding edge extending from the edge of the through-opening to the glass cup body are provided on the cup body shell, and the surrounding edge is enclosed to form a positioning groove, that is, the positioning groove is formed by the cup body shell to position the detection plate, so as to achieve structural simplification. The detection plate can be directly installed in the positioning groove on the outside of the cup body shell, so as to avoid the complication of the structure and the installation of the detection plate caused by the additional arrangement of tooling. After the detection plate is positioned in the positioning groove, the positioning groove is poured with glue. After standing for a period of time, the detection plate can be firmly fixed, so that the positioning and sealing of the detection plate are achieved in one step. The installation of the detection plate is more convenient, and the assembly steps are simplified. At the same time, the installation of the detection plate and the installation between the glass cup body and the cup body shell do not interfere with each other. The whole machine is easy to assemble, the assembly cost of the detection plate is reduced, and the structure of the whole machine is simplified.

[0009] In a preferred embodiment, the end surface of the surrounding edge is tightly matched with the outer side surface of the glass cup body, and the surrounding edge and the outer side surface of the glass cup body are combined to form the positioning groove.

[0010] By fitting the end face of the edge tightly with the outer side of the glass body, the glue is not easy to overflow from the gap between the edge and the glass body during the glue filling process, which ensures the effective use of the glue and solves the problem of difficult cleaning and glue waste after glue overflow. The edge and the outer side of the glass body are enclosed to form a positioning groove, which is conducive to shortening the distance between the detection plate and the glass body, shortening the detection distance, and realizing sensitive detection. In addition, the glue fills the matching gap between the detection plate and the glass body, reducing the influence of condensed water in the matching gap on the detection accuracy, thereby improving the detection sensitivity and detection accuracy of the detection plate and improving the sealing reliability of the detection plate.

[0011] In a preferred embodiment, the surrounding edge is arranged around the edge of the through-hole, and the upper end or the lower end of the detection plate abuts against the surrounding edge.

[0012] By arranging the surrounding edge to surround the edge of the through - opening, the all - around limiting of the detection board is achieved. The upper end or the lower end of the detection board abuts against the surrounding edge, so that the installation position of the detection board is accurate, improving the detection accuracy of the detection board. It is also convenient for multi - directional positioning of the detection board before potting, simplifying the potting and fixing operation of the detection board, improving the assembly efficiency, and reducing the installation cost.

The upper end of the detection board abuts against the upper surrounding edge to achieve precise positioning of the detection board. The lower surrounding edge is provided with a wire - passing hole for the lead wire of the detection board to pass through, avoiding problems such as the lead wire being bent in the positioning groove and causing the detection board to be unevenly installed. The structure is reliable.

[0015] In a preferred embodiment, the surrounding edge includes a first side surrounding edge and a second side surrounding edge that vertically extend along both side edges of the through - opening. The first side surrounding edge and the second side surrounding edge are not connected to form an opening.

[0016] The surrounding edge includes a first side surrounding edge and a second side surrounding edge that vertically extend along both side edges of the through - opening, achieving the limiting of the side edges of the two detection boards, avoiding the detection board from swaying and sliding during the potting process, facilitating the precise positioning of the detection board. The first side surrounding edge and the second side surrounding edge are not connected to form an opening, and the opening can be used for inserting the detection board or for the lead wire of the detection board to pass through. The structure is reliable.

[0017] In a preferred embodiment, the upper end of the positioning groove extends towards the top edge of the cup body housing to form an upper opening. The glass cup body protrudes outwards with a positioning portion, and the positioning portion is located at the upper opening. The upper end of the detection board abuts against the positioning portion.

[0018] More preferably, the positioning portion includes a positioning rib located in the positioning groove.

[0019] More preferably, the glass cup body includes a main body section sleeved in the cup body housing and a visible section connected above the main body section and protruding out of the cup body housing. The outer diameter of the visible section is enlarged relative to the main body section to form a step, and the positioning portion includes the step.

[0020] Through the positioning portion at the upper opening, the upper end of the detection board abuts against the positioning portion to achieve the positioning of the detection board. The installation height of the detection board is precise, improving the detection accuracy. Moreover, the positioning groove is open at the end, which can expand the vertical space of the through - opening, realize the height expansion of the detection board, and increase the detection range.

[0021] In a preferred embodiment, the cup body housing is formed by rolling a metal sheet around the glass cup body. The through hole is located at the connection of the two ends of the metal sheet, and the surrounding edge is a flanging provided at the two ends of the metal sheet and folded towards the glass cup body.

[0022] The cup body housing adopts a metal sheet structure, which makes the appearance look more advanced, and is convenient for the formation of the through hole and the surrounding edge. After the cup body housing is rolled, the through hole is naturally formed, and the surrounding edge is naturally formed by flanging the two ends of the metal sheet, simplifying the structure of the cup body housing.

[0023] More preferably, recessed portions are respectively provided at the two ends of the metal sheet. The two ends of the metal sheet are spliced, and the two recessed portions enclose to form the through hole;

[0024] Alternatively, a mating gap is provided between the two ends of the metal sheet, and the mating gap forms the through hole.

[0025] In a preferred embodiment, the liquid heater further includes a connecting member fixed to the outside of the cup body housing, and the connecting member hides the through hole.

[0026] In a preferred embodiment, the glass cup body includes a main body section sleeved in the cup body housing and a visible section connected above the main body section and exposed outside the cup body housing. The outer diameter of the visible section is enlarged relative to the main body section, and a step is formed between the main body section and the visible section. The top end of the cup body housing abuts against the step, and a sealing ring is provided between the step and the top end of the cup body housing.

[0027] The glass cup body includes a main body section and a visible section. The cup body housing is sleeved outside the main body section to achieve fixation and heat insulation protection. The visible section is exposed outside the cup body housing, which is convenient for users to observe the working conditions inside the glass cup body and improves the user experience. Moreover, a step is formed between the main body section and the visible section, and the top end of the cup body housing abuts against the step to achieve reliable axial limit between the cup body housing and the glass cup body. A sealing ring is provided between the step and the top end of the cup body housing to effectively seal the sandwich between the glass cup body and the cup body housing, preventing overflow or liquid droplets from flowing down along the cup mouth into the sandwich. For the case where the end of the through hole is open, the sealing ring can further improve the waterproofness of the detection board, avoiding damage or detection failure of the detection board due to water.

[0028] In a preferred embodiment, the detection board abuts against the bottom of the positioning groove, and divides the positioning groove into an inner cavity chamber close to the glass cup body side and an outer cavity chamber far from the glass cup body side. The inner cavity chamber is communicated with the outer cavity chamber, and the outer cavity chamber and the inner cavity chamber are filled with glue to encapsulate the detection board.

[0029] By abutting the detection plate against the bottom wall of the positioning groove, the detection distance of the detection plate is reduced, improving the detection sensitivity of the detection plate. At the same time, the positioning groove is divided into an inner cavity close to the glass body and an outer cavity far from the glass body by the detection plate, and the inner cavity communicates with the outer cavity, so that during the potting process, the potting glue fills the inner cavity and the outer cavity, sealing and fixing the detection plate in all directions, making the sealing of the detection plate comprehensive and reliable positioning.

[0030] In a preferred embodiment, the positioning groove has a bottom wall integrally formed with the surrounding edge, the outer end face of the bottom wall fits against the outer side face of the glass body, and the detection plate is potted and encapsulated in the positioning groove before installing the glass body.

[0031] More preferably, the thickness of the bottom wall is S, satisfying 0.3mm ≤ S ≤ 3mm.

[0032] The positioning groove has a bottom wall integrally formed with the surrounding edge, and the outer end face of the bottom wall fits against the outer side face of the glass body, that is, the cup body shell directly forms a positioning groove by being recessed from the outside to the inside. The positioning groove is defined by the cup body shell itself to directly position and install the detection plate, solving the installation problem of the detection plate in the double-layer cup body structure. Compared with methods such as setting a pushing member, the overall structure of the machine is simplified, the assembly cost of the detection plate is reduced, and the convenient installation of the detection plate is realized.

[0033] By setting the thickness S of the bottom wall between 0.3mm and 3mm, on the basis of effectively solving the installation problem of the detection plate in the double-layer cup body structure, it is possible to avoid the detection distance of the detection plate being too large due to S being too large, and avoid the strength of the cup body shell being insufficient due to S being too small, so as to improve the detection sensitivity of the detection plate on the basis of enhancing the reliability of the overall structure.

[0034] The detection plate is potted and encapsulated in the positioning groove before installing the glass body. During the installation of the detection plate, the cup body shell is relatively light, and it is labor-saving to pick up and align, thus facilitating the accurate positioning and fixing of the detection plate.

[0050] like Figure 1-5 As shown, the utility model provides a liquid heater in one embodiment, including a glass cup body 10, a cup body shell 20 mounted on the outside of the glass cup body 10, and a detection plate 30 for detecting the liquid level in the glass cup body 10 in the air. The cup body shell 20 is provided with a vertically extending through-hole 21 and a surrounding edge 40 extending from the edge of the through-hole 21 to the glass cup body 10. The surrounding edge 50 encloses a positioning groove 50, and the detection plate 30 is positioned in the positioning groove 50. The detection plate 30 is encapsulated by pouring glue into the positioning groove 50.

[0051] A liquid heater provided by the utility model includes a glass cup body and a cup body housing sleeved outside the glass cup body. The cup body housing can achieve heat insulation and noise reduction effects, avoid the problem of scalding hands, and reduce working noise. By providing a vertically extending through-hole in the housing and a surrounding edge extending from the edge of the through-hole towards the glass cup body, the surrounding edge encloses a positioning groove, that is, the detection board is positioned by means of the cup body housing itself, realizing structural integration, avoiding the complexity of structure and installation of the detection board caused by additional arrangement of tooling. The detection board is positioned in the positioning groove. By pouring glue into the positioning groove and waiting for a period of standing, the detection board can be firmly fixed on the outer wall of the glass cup body, realizing one-step positioning and sealing of the detection board, making the installation of the detection board more convenient, streamlining the assembly steps. At the same time, the installation of the detection board and the installation between the glass cup body and the cup body housing do not interfere with each other, making the whole machine assembly simple, reducing the assembly cost of the detection board, and simplifying the structure of the whole machine.

[0052] It should be noted that the specific forms of the positioning groove and the surrounding edge 40 in the present utility model are not limited. For example:

[0053] Embodiment 1, as Figure 1-5 shown, the end face of the surrounding edge 40 is in close fit with the outer side surface of the glass cup body 10 to enclose the positioning groove 50.

[0054] More preferably, the surrounding edge 40 is arranged around the edge of the through-hole 21, and the upper end or the lower end of the detection board 30 abuts against the surrounding edge 40. More preferably, in this embodiment, as Figure 2 、 3 shown, the surrounding edge 40 includes a first side surrounding edge 41 and a second side surrounding edge 42, an upper surrounding edge 43 and a lower surrounding edge 44 located on both sides of the edge of the through-hole 21, and the four surrounding edges surround the through-hole 21.

[0055] More preferably, as Figure 3 shown, the upper end of the detection board 30 abuts against the upper surrounding edge 43, and the lower surrounding edge 44 is provided with a wire passing hole 32. For example Figure 1 shown, the lead wire 31 of the detection board 30 passes out from its lower end and is connected to the control board 60 through the wire passing hole 32.

[0056] In this embodiment, as Figure 1 shown, the liquid heater is a food processor, and further includes a motor 80 connected to the control board 60 and a crushing knife 70 driven by the motor 80. The motor 80 is arranged below the glass cup body 10, and the crushing knife 70 rotates to cut materials to realize functions such as pulping and juice preparation.

[0057] Of course, it should be noted that the way the surrounding edge surrounds the through-hole 21 is not limited to the one in this embodiment. In fact, in other embodiments, the through-hole 21 can be selected as an ellipse, and the surrounding edge is elliptical to surround the through-hole 21; or, the through-hole 21 is an irregular shape, such as an irregular quadrilateral, pentagon, etc., and the surrounding edge surrounds the through-hole 21.

[0058] In this embodiment, by tightly fitting the end face of the surrounding edge with the outer side surface of the glass cup body, during the glue injection process, the glue is not likely to overflow from the gap between the surrounding edge and the glass cup body, ensuring the effective utilization of the glue, and also solving the problems of difficult cleaning after glue overflow and waste of glue. The surrounding edge and the outer side surface of the glass cup body enclose a positioning groove, which is beneficial to shortening the distance between the detection plate and the glass cup body, shortening the detection distance, and realizing sensitive detection. Moreover, the glue fills the fitting gap between the detection plate and the glass cup body, reducing the influence on the detection accuracy caused by the presence of condensed water in the fitting gap, thereby improving the detection sensitivity and accuracy of the detection plate, and enhancing the sealing reliability of the detection plate.

[0059] By arranging the surrounding edge to surround the edge of the through-hole 21, the purpose of all-round limiting of the detection plate 30 is achieved. The upper end or the lower end of the detection plate 30 abuts against the surrounding edge, making the installation position of the detection plate 30 accurate, improving the detection accuracy of the detection plate 30, and also facilitating the multi-directional positioning of the detection plate 30 before glue injection, simplifying the glue injection and fixing operation of the detection plate 30, improving the assembly efficiency, and reducing the installation cost.

[0060] In this embodiment, as Figure 5 shown, preferably, the detection plate 30 abuts against the outer side surface of the glass cup body 10, and the positioning groove 50 is divided into an inner cavity 51 close to the glass cup body 10 and an outer cavity 52 far from the glass cup body 10, and the inner cavity 51 communicates with the outer cavity 52.

[0061] Specifically, the present invention does not limit the communication method between the inner cavity and the outer cavity. As Figure 3 、 Figure 5 shown, a protrusion 45 is provided on the first side surrounding edge 41, the detection plate 30 is clamped between the protrusion 45 and the second side surrounding edge 42, and a glue passing gap is formed between the detection plate 30 and the second side surrounding edge 42. The glue passing gap communicates the inner cavity with the outer cavity, so that the glue fills the inner cavity and the outer cavity to realize the encapsulation of the detection plate 30.

[0062] In this embodiment, by abutting the detection plate 30 against the outer side surface of the glass body 10, the detection distance of the detection plate 30 is reduced, improving the detection sensitivity of the detection plate 30. At the same time, the positioning groove 50 is divided into an inner cavity chamber close to the glass body 10 and an outer cavity chamber far from the glass body 10 by the detection plate 30, and the inner cavity chamber communicates with the outer cavity chamber. During the glue filling process, the glue fills the inner cavity chamber and the outer cavity chamber, providing multi-directional sealing and fixing for the detection plate 30, making the sealing of the detection plate 30 comprehensive and reliable positioning.

[0063] Of course, in other embodiments, optionally, a glue passing groove is provided inside the peripheral edge, and the inner cavity chamber communicates with the outer cavity chamber through the glue passing groove, so that the glue fills the inner cavity chamber and the outer cavity chamber to realize the encapsulation of the detection plate 30. The above encapsulation structure of the detection plate 30 is still applicable to other embodiments.

[0064] In addition, it should be noted that the present utility model does not limit the specific sleeving relationship between the glass body 10 and the cup body housing 20. For example, in this embodiment, as Figure 2 shown, the glass body 10 includes a main body section 11 sleeved in the cup body housing 20 and a visible section 12 connected above the main body section 11 and exposed outside the cup body housing 20. The outer diameter of the visible section 12 is enlarged relative to the main body section 11, and a step 13 is formed between the main body section 11 and the visible section 12. The top end of the cup body housing 20 abuts against the step 13, and a sealing ring 14 is provided between the step 13 and the top end of the cup body housing 20.

[0065] The glass body 10 includes a main body section 11 and a visible section 12. The cup body housing 20 is sleeved outside the main body section 11 to achieve fixation and heat insulation protection. The visible section 12 is exposed outside the cup body housing 20, facilitating the user to observe the working conditions inside the glass body 10 and improving the user experience. Moreover, a step 13 is formed between the main body section 11 and the visible section 12, and the top end of the cup body housing 20 abuts against the step 13 to achieve reliable axial limit between the cup body housing 20 and the glass body 10. A sealing ring 14 is provided between the step 13 and the top end of the cup body housing 20, effectively sealing the interlayer between the glass body 10 and the cup body housing 20 to prevent overflow or liquid droplets from flowing down along the cup mouth into the interlayer. For the case where the end opening of the through port 21 is open, the sealing ring 14 can further improve the waterproof property of the detection plate 30, avoiding water damage or detection failure of the detection plate 30.

[0066] Of course, the above sleeving relationship between the glass body 10 and the cup body housing 20 is still applicable to other embodiments. Moreover, the present utility model is not limited thereto. In other embodiments, optionally, the glass body 10 is completely wrapped in the cup body housing 20 to achieve comprehensive heat insulation and noise reduction.

[0067] In addition, it should be noted that the liquid heater provided by the present utility model is not limited to the motor 80 under-mounted food processor provided in this embodiment. It can also be a head-type soybean milk machine, a wall breaker, a food processor that does not need to be hand-washed, a health kettle, a boiling water pot, etc.

[0068] Embodiment 2, different from Embodiment 1, in this embodiment, the surrounding edge only includes the upper surrounding edge and the lower surrounding edge located at both ends of the edge of the through-hole 21. The upper end of the detection plate 30 abuts against the upper surrounding edge, and the lower surrounding edge is provided with a wire passing hole 32.

[0069] It should be noted that, in order to realize pouring glue into the positioning groove 50 without leaking glue, in this embodiment, an additional bracket can be used. The bracket, together with the upper surrounding edge and the lower surrounding edge, defines the glue to prevent the glue from flowing out of the positioning groove 50, thus realizing the reliable encapsulation of the detection plate 30.

[0070] The surrounding edge includes the upper surrounding edge and the lower surrounding edge located at both ends of the edge of the through-hole 21. The upper end of the detection plate 30 abuts against the upper surrounding edge to realize the precise positioning of the position of the detection plate 30. The lower surrounding edge is provided with a wire passing hole 32 for the lead wire 31 of the detection plate 30 to pass through, avoiding problems such as the lead wire 31 being bent in the positioning groove 50 and causing the detection plate 30 to be unevenly installed. The structure is reliable.

[0071] Embodiment 3, as Figure 6 shown, different from Embodiment 1, the surrounding edge extends along the edge of the through-hole 21 and forms an opening at the end of the through-hole 21. The opening includes an upper opening 46 located at the upper end of the through-hole 21 and a lower opening 47 located at the lower end of the through-hole 21. The glass cup body 10 protrudes outward with a positioning portion located at the upper opening, and the upper end of the detection plate 30 abuts against the positioning portion.

[0072] Specifically, in this embodiment, the surrounding edge includes a first side surrounding edge 41 and a second side surrounding edge 42 that vertically extend along both side edges of the through-hole 21. The first side surrounding edge 41 and the second side surrounding edge 42 are not connected to form an opening. More preferably, in this embodiment, the glass cup body 10 includes a main body section 11 sleeved in the cup body housing 20 and a visible section 12 connected above the main body section 11 and exposed outside the cup body housing 20. The outer diameter of the visible section 12 is enlarged relative to the main body section 11 to form a step 13, and the positioning portion includes the step 13.

[0073] Of course, as other preferred embodiments, the positioning portion can be selected to include a positioning rib located in the positioning groove 50, such as a horizontal rib.

[0074] In this embodiment, an opening is formed at the end of the through - opening 21, and a positioning portion protruding outward at the opening is provided on the glass cup body 10. The upper end of the detection plate 30 abuts against the positioning portion, realizing the positioning of the detection plate 30. The installation height of the detection plate 30 is accurate, improving the detection accuracy. Moreover, since the through - opening 21 has an opening at the end, the vertical space of the through - opening 21 can be expanded, realizing an increase in the height of the detection plate 30 and increasing the detection range.

[0075] The surrounding edge includes a first side surrounding edge and a second side surrounding edge that vertically extend along the two side edges of the through - opening 21, realizing the limit of the side edges of the two detection plates 30, preventing the detection plates 30 from swaying and sliding during the potting process, facilitating the accurate positioning of the detection plates 30. An opening is formed where the first side surrounding edge and the second side surrounding edge are not connected. The opening can be used for inserting the detection plate 30 or for the leads 31 of the detection plate 30 to pass through, and the structure is reliable.

[0076] In this embodiment, optionally, the cup body housing 20 is formed by rolling a metal thin plate around the glass cup body 10. The through - opening 21 is located at the connection of the two ends of the metal thin plate along the circumferential direction of the glass cup body 10, and the surrounding edge is a flanging provided at both ends of the metal thin plate and folded towards the glass cup body 10.

[0077] Regarding the forming method of the through - opening, preferably, recessed portions are respectively provided at both ends of the metal thin plate. The two ends of the metal thin plate are spliced, and the two recessed portions enclose to form the through - opening;

[0078] Of course, in other embodiments, it can also be that a fitting gap is provided between the two ends of the metal thin plate, and the fitting gap forms the through - opening.

[0079] In addition, in a preferred embodiment, the liquid heater further includes a connecting member fixed to the outside of the cup body housing. The connecting member hides the through - opening. The connecting member can be, for example, a handle. In this embodiment, the connecting member not only hides the through - opening but also indirectly connects the two ends of the metal thin plate.

[0080] The cup body housing 20 adopts a metal thin plate structure, making the appearance more high - grade, and facilitating the formation of the through - opening 21 and the surrounding edge. After rolling, the cup body housing 20 naturally forms the through - opening 21 and the surrounding edge is naturally formed by the flanging of the two ends of the metal thin plate, simplifying the structure of the cup body housing 20. It can be understood that the above - mentioned structure of the cup body housing is still applicable to other embodiments of the present invention.

[0081] In another embodiment of the present invention, a liquid heater is further provided, for example:

[0082] Embodiment 4, such as Figure 7 、 Figure 8As shown, the liquid heater includes a glass cup body, a cup body shell 20 sleeved on the outside of the glass cup body, and a strip-shaped detection plate for detecting the liquid level in the glass cup body in the air. The cup body shell is provided with a vertically extending through-hole and a surrounding edge extending from the edge of the through-hole to the glass cup body. Different from the embodiment 1, in this embodiment, the positioning groove has a groove bottom wall integrally formed with the surrounding edge, and the outer end face of the groove bottom wall is attached to the outer side face of the glass cup body. The detection plate is glued and encapsulated in the positioning groove before the glass cup body is installed. Specifically, the outer end face of the groove bottom wall is a plane or a curved surface that is suitable for the outer side face of the glass cup body.

[0083] In this embodiment, a surrounding edge and a groove bottom wall are provided, that is, a vertically extending positioning groove 50 is integrally formed from the outside to the inside on the outer wall of the cup body shell 20 , and the detection board is positioned in the positioning groove 50 , and the detection board is encapsulated by injecting glue into the positioning groove 50 .

[0084] Of course, in order to prevent the thickness of the cup shell 20 from having too much influence on the detection of the detection board 30, preferably, as Figure 8 As shown, the thickness of the bottom wall of the groove is S, that is, the thickness S of the bottom wall of the positioning groove 50 formed by the cup body shell 20 satisfies: 0.3mm≤S≤3mm. Avoid S being too small, less than 0.3mm, resulting in insufficient strength of the cup body shell, and avoid S being too large, greater than 3mm, resulting in too large a barrier distance between the detection plate and the liquid in the glass cup body, affecting the detection sensitivity. Therefore, satisfying 0.3mm≤S≤3mm can effectively solve the installation problem of the detection plate in the double-layer cup body structure, improve the sensitivity of the detection plate, and achieve structural reliability.

[0085] The detection board is glued and sealed in the positioning groove before the glass cup body is installed. During the installation of the detection board, the cup body shell is relatively light, and it is labor-saving to take and align, so that the detection board is convenient for accurate positioning and fixing.

[0086] Of course, the installation sequence of the detection board is not limited to the above one. For example, in other embodiments, after the glass cup body is installed into the cup body shell, the detection board is glued and fixed in the positioning groove.

[0087] In addition, it should be noted that the surrounding edge structure in this implementation example can also be selected as the surrounding edge structure in implementation examples 1-3, and the specific structure will not be repeated here.

[0088] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0089] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0090] The above are only embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
