Description

Technical Field

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

[0002] With the advancement of science and technology, the anti-overflow detection method currently used in kitchen appliances is mainly detection board detection. For example, the patent with application number CN201610753199.4 discloses that a signal PCB board is arranged between the cup body and the hand-held handle of the food processor, and a metal sheet is arranged on the signal PCB board. When the volume of the food in the cup body changes, the capacitor formed by the metal sheet and the food in the cup body will generate a charge signal, and the signal PCB board will then transmit the charge signal to the control circuit board. The control circuit board can judge the height of the current food liquid level in the cup body according to the transmitted signal. At the same time, the control circuit board controls the electric heating element or the knife group according to the current liquid level, thereby effectively controlling the change of the liquid level of the food and preventing food from overflowing. However, in this solution, there is an installation gap between the signal PCB board and the cup body, and the signal PCB board has no reliable positioning structure relative to the cup body, and the relative positions of the two are not fixed. Based on this, the signal PCB board cannot accurately identify the overflow signal. Therefore, the above-mentioned food processor still does not completely solve the problem of food overflow.

[0003] In order to make the detection plate and the cup body have a relatively better positioning relationship. The applicant previously proposed a patent with application number CN201720526032.4. The patent discloses that the capacitive sensing plate is positioned on the outer wall of the glass cup through a handle shell. During the installation process, two symmetrical and oppositely spliced ​​and fixed handle covers need to clamp the handle while clamping the capacitive sensing plate, so as to achieve the positioning of the capacitive sensing plate while fixing the handle shell, and ensure the relative position relationship between the capacitive sensing plate and the glass cup body. Although in this solution, the capacitive sensing plate and the glass cup body are in a relatively fixed relationship and no displacement will occur between the two, in this structure, a handle is required to be provided on the glass cup body to position the handle shell, and then the capacitive sensing plate is fixed and limited by the positioning of the handle shell. Since the outer wall of the glass cup is an arc-shaped structure and the sensing plate is a strip-shaped flat plate, the sensing plate is directly positioned on the smooth glass cup through the handle shell, which may cause the sensing plate to slide relative to the cup body and make positioning of the sensing plate difficult, resulting in inaccurate assembly position of the sensing plate and affecting detection accuracy. Therefore, not only is the installation structure complicated, but there is an assembly error between the handle shell and the handle, or when the sensing plate slides, the capacitive sensing plate will detect inaccurate liquid level signals, and there may also be unreliable sealing of the matching gap.

[0004] In the process of further research, the applicant also proposed a patent with application number CN2024103319154, which uses a bracket to encapsulate the detection board on the outside of the glass body by glue pouring. However, during the glue pouring process, it is necessary to set up a separate bracket, use the bracket to frame the detection board on the curved outer wall of the glass body, and then perform the glue pouring operation. After the glue solidifies, install the handle, and use the handle to block the positioning bracket and the glue pouring port. This method can reliably and accurately fix the detection board to the curved outer wall of the glass, but there are many auxiliary parts, many installation procedures during the assembly process, complicated assembly, and the handle needs to be installed after the glue solidifies, so the assembly takes a long time.

[0008] The utility model provides a liquid heater with a simple structure, which comprises a handle including a cover plate and a grip connected to the cover plate, and the cover plate is extended vertically and a fitting portion is arranged on the edge to fit with the peripheral wall of the glass cup body, so that the cover plate and the peripheral wall of the glass cup body enclose a receiving cavity for receiving the detection plate, and the detection plate is limited in the receiving cavity. Therefore, the multifunctionality of the handle is realized, which is convenient for users to take and can realize the installation and positioning of the detection plate during the assembly process, reduce the space occupied, and help to reduce the radial size of the whole machine, eliminate the need for additional brackets to position the detection plate, simplify the positioning steps and the overall structure, provide reliable and accurate positioning for the glue filling and fixing of the detection plate, and realize reliable and accurate positioning of the detection plate; in addition, in the cover After the plate is installed on the glass cup body, glue is poured into the accommodating cavity through the glue inlet to encapsulate the detection plate. The glue fills the accommodating cavity so that the gap between the detection plate and the peripheral wall of the glass cup body is reliably fixed and sealed, which not only ensures the reliability and sealing of the positioning and fixation of the detection plate on the peripheral wall of the glass cup body, but also realizes the fixation of the handle after the glue solidifies, improves the connection strength between the handle and the glass cup body, and enhances the connection strength of each part of the glass cup body, the detection plate, and the handle, and greatly improves the reliability of the overall structure; because the cover plate is provided with a fitting part, in the process of pouring glue into the accommodating cavity, the glue is not easy to overflow from the gap between the cover plate and the glass cup body, which ensures the effective use of the glue and solves the problem of difficult cleaning and glue waste after glue overflow. Moreover, the installation of the cover plate of the handle does not require waiting for the glue to solidify, which reduces the waiting time during the assembly process, greatly shortens the assembly time of the whole machine, improves assembly efficiency, and reduces production costs. In summary, the liquid heater provided by the utility model utilizes the handle to realize multiple functions, simplifies the positioning and installation of the detection plate, and realizes reliable fixation of the handle while fixing the detection plate by glue, thereby realizing rapid assembly of the whole machine and simplification of the structure, so that both the detection plate and the handle can be fixed to the glass cup body more reliably and accurately.

[0009] In a preferred embodiment, the cover plate is provided with a connecting portion connected to the handle, and the glue inlet is arranged at the connecting portion.

[0015] By directly hiding the glue inlet with the handle or closing the glue inlet with the cover, dust, liquid or other debris can be prevented from entering the accommodating cavity, protecting the detection board, and the overall visual effect will not be affected by the exposure of the glue inlet, making the appearance more neat and beautiful.

[0016] In a preferred embodiment, the cover plate is provided with a pressing portion, and the pressing portion presses the detection plate against the peripheral wall of the glass body;

[0017] The detection plate is pressed against the peripheral wall of the glass body by providing a pressing portion. The pressing portion can pre-position the detection plate before glue pouring, so that the detection plate is accurately positioned, avoiding displacement of the detection plate before and during glue pouring, and effectively performing overflow prevention detection. After glue pouring, the pressing portion plays an auxiliary positioning role in the fixed connection between the detection plate and the glass body, ensuring a reliable connection between the detection plate and the glass body, so as to further ensure a reliable connection between the handle and the glass body.

[0018] In a preferred embodiment, the edge of the detection plate abuts against the inner side of the fitting portion to limit position.

[0023] In a preferred embodiment, a limiting rib is convexly provided on the inner side wall of the fitting portion, and the limiting rib abuts against the edge of the detection plate to limit the position, so that a glue gap is formed between the edge of the detection plate and the fitting portion, and the inner chamber and the outer chamber are connected through the glue gap;

[0024] Alternatively, a concave communicating groove is provided on the inner side wall of the fitting portion, and the inner chamber and the outer chamber are communicated with each other through the communicating groove.

[0025] The outer surface of the peripheral wall of the glass cup body is curved, and the detection plate divides the accommodating chamber into an inner chamber located on one side of the glass cup body and an outer chamber located on one side of the positioning plate. A glue inlet connected to the accommodating chamber is also provided on the outer wall of the cover plate. After the detection plate is pre-positioned in the accommodating chamber, a glue filling process is adopted to fill glue into the accommodating chamber through the glue inlet. After standing for a period of time, the glue liquid can pass through the glue gap or the connecting groove to fill the inner chamber and the outer chamber, so that the glue liquid is filled into every corner of the accommodating chamber, so as to realize the packaging and fixation of the rigid detection plate on the outer wall of the curved glass cup body, which not only ensures the reliability of the positioning and fixation of the detection plate, but also realizes the waterproof sealing of the detection plate, and also realizes the reliable fixation of the handle, which solves the problem of fixing the rigid detection plate on the outer wall of the curved glass cup body in the prior art.

[0026] In a preferred embodiment, a positioning plane is provided on the peripheral wall of the glass body, and the detection plate is arranged close to the positioning plane.

[0027] By setting the positioning plane, the fit between the detection plate and the glass cup body is further improved. The detection plate is set close to the positioning plane, so that the distance between the detection plate and the liquid in the glass cup body is uniform and accurate, which improves the detection accuracy of the detection plate and is also conducive to the pre-positioning of the detection plate, making the installation of the detection plate easier.

[0043] like Figure 1-6As shown, the utility model provides a liquid heater with a simple structure in one embodiment, including a glass cup body 10, a handle 30 fixed on the side of the glass cup body 10, and a strip-shaped detection plate 20 for detecting the liquid level in the air, the handle 30 includes a cover plate 31 and a grip 32 connected to the cover plate 31, the cover plate 31 extends vertically along the peripheral wall of the glass cup body 10, and the edge of the cover plate 31 is convexly provided with a fitting portion 311 that fits with the peripheral wall of the glass cup body 10, the cover plate 31 and the peripheral wall of the glass cup body 10 enclose a receiving cavity 40 for accommodating the detection plate 20, the detection plate 20 is limited in the receiving cavity 40, the cover plate 31 is provided with a glue inlet 314 connected to the receiving cavity 40, after the cover plate 31 is installed on the glass cup body 10, glue is poured into the receiving cavity 40 through the glue inlet 314 to encapsulate the detection plate 20.

[0044] The utility model provides a liquid heater with a simple structure. The handle 30 is configured to include a cover plate 31 and a grip 32 connected to the cover plate 31. The cover plate 31 is extended vertically and a fitting portion 311 is provided at the edge to fit with the peripheral wall of the glass cup body 10, so that the cover plate 31 and the peripheral wall of the glass cup body 10 are enclosed to form a receiving cavity 40 for accommodating the detection plate 20. The detection plate 20 is limited in the receiving cavity 40. Therefore, the multifunctionality of the handle 30 is realized, which can not only facilitate the user to take it, but also realize the installation and positioning of the detection plate 20 during the assembly process, reduce the space occupied, and help to reduce the radial size of the whole machine, eliminate the need for additional brackets to position the detection plate 20, simplify the positioning steps and the overall structure, provide reliable and accurate positioning for the glue filling and fixation of the detection plate 20, and realize reliable and accurate positioning of the detection plate 20; in addition, when the cover plate 31 is arranged After being installed in the glass cup body 10, glue is poured into the accommodating cavity 40 through the glue inlet 314 to encapsulate the detection board 20. The glue fills the accommodating cavity 40, so that the gap between the detection board 20 and the peripheral wall of the glass cup body 10 is reliably fixed and sealed, which not only ensures the reliability and sealing of the positioning and fixation of the detection board 20 on the peripheral wall of the glass cup body 10, but also realizes the fixation of the handle 30 after the glue solidifies, and improves the connection strength between the handle 30 and the glass cup body 10, so that the connection strength of each part of the glass cup body 10, the detection board 20 and the handle 30 is enhanced, and the reliability of the overall structure is greatly improved; because the cover plate 31 is provided with a fitting portion 311, in the process of pouring glue into the accommodating cavity 40, the glue is not easy to overflow from the gap between the cover plate 31 and the glass cup body 10, which ensures the effective use of the glue and solves the problems of difficult cleaning and waste of glue after overflow. Furthermore, the installation of the cover plate 31 of the handle 30 does not require waiting for the glue to solidify, which reduces the waiting time during the assembly process, greatly shortens the assembly time of the entire machine, improves assembly efficiency, and reduces production costs.

[0045] It should be noted that the present invention does not limit the location of the glue inlet 314. Figure 2The cover plate 31 is provided with a connecting portion 310 connected to the handle 32 , and the glue inlet 314 is optionally provided at the connecting portion 310 ; or, the glue inlet 314 and the projection of the handle 32 on the cover plate 31 are staggered.

[0046] The present invention is combined with the specific form of the handle 30 and takes the setting of the glue inlet 314 at the connecting part as an example to explain:

[0047] Implementation example 1, such as Figure 1-6 As shown, the cover plate 31 is provided with a connection portion 310 connected to the handle 32, and the glue inlet 314 is provided at the connection portion 310. In this embodiment, the handle 32 includes a base body integrally connected to the cover plate 31 and a handle cover 33 separately provided on the outside of the base body, the base body and the handle cover 33 enclose a handle cavity, and the glue inlet 314 is hidden in the handle cavity.

[0048] In this embodiment, the connection part includes an upper connection part and a lower connection part, so that the base of the handle 32 is connected to the cover plate 31 in a ring shape, and an opening is provided in one of the upper connection part and the lower connection part to serve as the glue inlet 314. More preferably, openings can also be provided in the upper connection part and the lower connection part, respectively, one of which serves as the glue inlet 314 and the other serves as the exhaust port.

[0049] In this implementation example, preferably, the handle cover 33 is connected to the base body by snap-fit ​​connection to avoid the situation where screws are exposed by screws or the like, thereby improving the overall appearance.

[0050] In this embodiment, by setting the glue inlet 314 at the connection part, the worker can avoid the interference of the handle 32 during the glue pouring operation to the glue inlet 314, which is convenient for operation and improves the glue pouring efficiency and the fixing efficiency of the detection board 20. The handle 32 includes a base body integrally connected with the cover plate 31 and a handle cover 33 covering the outside of the base body. Under the premise of using the structure of the traditional handle 30, the handle 30 can be positioned on the detection board 20, and the detection board 20 and the handle 30 can be reliably fixed, eliminating the trouble of changing the structure of the handle 30 and re-molding, thereby reducing the structural changes to the handle 30. At the same time, the glue inlet 314 is hidden in the handle cavity, and the original structure of the handle 30 is used to hide the glue inlet 314, reducing the possibility of dust, liquid or other debris entering, making full use of the internal space of the handle 30, making the structure more compact, and not affecting the overall visual effect due to the exposure of the glue inlet 314, and the appearance is more neat and beautiful.

[0051] Of course, based on this embodiment, the handle 32 can also be connected to the upper part of the cover plate 31 , and the handle 32 and the lower end of the cover plate 31 are opened to form an open handle 30 .

[0052] Implementation Example 2, such as Figure 7-8As shown, what is different from Implementation Example 1 is that in this implementation example, the handle 32 is separately connected to the cover plate 31. Optionally, the handle 32 and the cover plate 31 are connected by snap fixation or screw fixation. After glue is poured into the accommodating cavity 40, the handle 32 is connected to the cover plate 31 to hide the glue inlet 314, and a cup cover 11 is provided on the glass cup body 10.

[0053] In this embodiment, the upper end of the handle 32 is connected to the cover plate 31 , and the lower end of the handle 32 and the lower end of the cover plate 31 are open to form an open handle 30 .

[0054] In fact, the upper end and the lower end of the grip 32 may also be connected to the cover plate 31 respectively to form a ring-shaped handle.

[0055] Implementation Example 3 is different from Implementation Example 1 in that, in this implementation example, the grip 32 is an independent component integrally connected to the cover plate 31 , and the handle 30 also includes a baffle that closes the glue inlet 314 . Optionally, the baffle only blocks the glue inlet 314 .

[0056] By directly hiding the glue inlet 314 with the handle 32 or closing the glue inlet 314 with a cover, dust, liquid or other debris can be prevented from entering the accommodating cavity 40, protecting the detection board 20, and the overall visual effect will not be affected by the exposure of the glue inlet 314, making the appearance more neat and beautiful.

[0057] It should be noted that the present invention does not limit the limiting method between the cover plate 31 and the detection plate 20, for example:

[0058] In a preferred embodiment, referring to Example 1 Figure 1 , Figure 4 As shown, the cover plate 31 is provided with a pressing portion 312, and the pressing portion 312 presses the detection plate 20 against the peripheral wall of the glass cup body 10. Specifically, as shown in FIG. Figure 4 As shown, the pressing portion 312 is the inner side surface of the cover plate 31 . Of course, pressing ribs may be protruded from the inner side surface of the cover plate 31 to form the pressing portion 312 .

[0059] More preferably, if Figure 4 As shown, the fitting portion 311 is a convex edge of the cover plate 31 protruding toward the glass cup body 10 , and a limiting rib 313 is protruding from the inner side wall of the convex edge, and the limiting rib 313 abuts against the edge of the detection plate 20 for limiting position.

[0060] By setting the pressing portion 312 to press the detection plate 20 against the peripheral wall of the glass cup body 10, the pressing portion 312 can pre-position the detection plate 20 before glue pouring, so that the positioning of the detection plate 20 is accurate, avoiding the displacement of the detection plate 20 before and during glue pouring, and effectively performing overflow prevention detection. After glue pouring, the pressing portion 312 plays an auxiliary positioning role in the fixed connection between the detection plate 20 and the glass cup body 10, ensuring the reliable connection between the detection plate 20 and the glass cup body 10, so as to further ensure the reliable connection between the handle 30 and the glass cup body 10.

[0061] In fact, in another preferred embodiment, the edge of the detection plate 20 abuts against the inner side of the fitting portion 311 to limit the position.

[0062] By abutting the edge of the detection board 20 against the inner side of the fitting portion 311 for limiting position, a pre-positioning effect is achieved to avoid displacement of the detection board 20 before and during glue pouring, which would cause errors in the detection position of the detection board 20, thereby achieving accurate and reliable detection.

[0063] In the present invention, the fixing method of the cover plate 31 and the glass body 10 can be selected as follows:

[0064] In a preferred embodiment, referring to Figure 1 , Figure 3 , Figure 4 As shown, the top of the cover plate 31 has a hook portion 315 hooked on the edge of the glass body 10, and the cover plate 31 is pre-positioned on the glass body 10 through the hook portion;

[0065] Alternatively, a cup holder is fixed at the bottom of the glass cup body 10, and the bottom of the cover plate 31 has a pre-positioning structure that matches the cup holder. The pre-positioning structure is, for example, an insert plate provided at the bottom of the cover plate, and a slot is provided in the cup holder, and the insert plate is plugged and matched with the slot;

[0066] Alternatively, adhesive is provided on the end surface of the fitting portion 311 , and the cover plate 31 is fixed to the outer surface of the peripheral wall of the glass cup body 10 by the adhesive.

[0067] Whether by setting a hook portion on the top of the cover plate 31 or using a pre-positioning structure or adhesive that cooperates with the cup holder on the bottom of the cover plate 31, the pre-positioning between the cover plate 31 and the glass cup body 10 can be achieved, and the detection plate 20, the cover plate 31 and the glass cup body 10 can be directly fixed after the glue filling is completed. Of course, the above-mentioned hook portion, pre-positioning structure or adhesive can also be used to achieve a double reinforcement effect on the detection plate 20, thereby improving the connection strength of each part and preventing the liquid heater from falling and causing problems such as loose connection.

[0068] In a preferred embodiment, referring to Figure 1-6As shown, the outer surface of the peripheral wall of the glass cup body 10 is curved, and the detection plate 20 divides the accommodating chamber 40 into an inner chamber 41 located on one side of the glass cup body 10 and an outer chamber 42 located on one side of the positioning plate. The glue inlet 314, the inner chamber 41 and the outer chamber 42 are connected, and a limiting rib 313 is convexly provided on the inner wall of the fitting portion 311. The limiting rib 313 abuts against the edge of the detection plate 20 for limiting, and a glue gap is formed between the edge of the detection plate 20 and the fitting portion 311, and the inner chamber 41 and the outer chamber 42 are connected through the glue gap.

[0069] Of course, in other embodiments, a recessed connecting groove may be optionally provided on the inner wall of the fitting portion 311, and the inner chamber 41 and the outer chamber 42 are connected through the connecting groove. Optionally, one side of the detection plate 20 is fitted with the inner wall of the fitting portion 311; or both sides of the detection plate 20 are fitted with the inner wall of the fitting portion 311.

[0070] The outer surface of the peripheral wall of the glass cup body 10 is curved, and the detection plate 20 divides the accommodating chamber 40 into an inner chamber 41 located on one side of the glass cup body 10 and an outer chamber 42 located on the side of the positioning plate. A glue inlet 314 connected to the accommodating chamber 40 is also provided on the outer wall of the cover plate 31. After the detection plate 20 is pre-positioned in the accommodating chamber 40, a glue filling process is adopted to fill glue into the accommodating chamber 40 through the glue inlet 314. After standing for a period of time, the glue can pass through the glue gap or the connecting groove to fill the inner chamber 41 and the outer chamber 42, so that the glue is filled into every corner of the accommodating chamber 40, so as to realize the packaging and fixation of the rigid detection plate 20 on the outer wall of the curved glass cup body 10, which not only ensures the reliability of the positioning and fixation of the detection plate 20, but also realizes the waterproof sealing of the detection plate 20, and also realizes the reliable fixation of the handle 30, which solves the problem of fixing the rigid detection plate 20 on the outer wall of the curved glass cup body 10 in the prior art.

[0071] In fact, in order to make the detection plate 20 fit tightly against the peripheral wall of the glass body 10, in other preferred embodiments, a positioning plane is optionally provided on the peripheral wall of the glass body 10, and the detection plate 20 is provided tightly against the positioning plane.

[0072] By setting the positioning plane, the fit between the detection plate 20 and the glass cup body 10 is further improved. The detection plate 20 is set close to the positioning plane, so that the distance between the detection plate 20 and the liquid in the glass cup body 10 is uniform and accurate, which improves the detection accuracy of the detection plate 20 and is also beneficial to the pre-positioning of the detection plate 20, making the installation of the detection plate 20 easier.

[0073] It should be noted that the detection board provided by the utility model can realize the detection of water level signals as well as the detection of overflow prevention signals, and a plurality of capacitor electrodes can also be arranged on the detection board for detecting different overflow prevention positions.

[0074] In addition, it should be noted that the liquid heater of the present invention is not limited. The liquid heater can be selected as the health pot in the embodiment 1, including a base 50 and a glass cup body 10 detachably mounted on the base 50. Figure 6 Alternatively, the liquid heater may be a food processor in Example 2, comprising a glass body 10, a motor 70 integrally disposed at the bottom of the glass body 10, and a crushing knife 60 disposed in the glass body 10 and driven by the motor, Figure 8 .

[0075] In fact, liquid heaters can also be used in soymilk machines with motors mounted on top, wall-breaking machines with separate cups and bases, and food processors that can automatically discharge and clean without hands-washing. In addition, liquid heaters can also be used as heating appliances for making beverages such as boiling soymilk and rice paste, such as water kettles and health kettles.
