Description

Technical Field

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

[0002] The prior art CN201610753199.4 discloses that a signal PCB board is arranged between the cup body and the hand-held handle of a food processor. A metal sheet is arranged on the signal PCB board. When the volume of food in the cup body changes, a capacitor formed by the metal sheet and the food in the cup body will generate a charge signal. The signal PCB board then transmits the charge signal to the control circuit board. The control circuit board can judge the height of the food liquid level in the current cup body according to the transmitted signal. At the same time, the control circuit board further controls the electric heating element or the knife set according to the current liquid level height, so as to effectively control the change of the food liquid level and prevent food from overflowing. However, there is an installation gap between the signal PCB board and the cup body in this solution, and there is no reliable positioning structure for the signal PCB board relative to the cup body, and their relative positions 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 enable the detection board and the cup body to have a relatively better positioning relationship. The applicant previously filed a patent with the application number CN201720526032.4. This patent discloses that a capacitive induction board is positioned on the outer side wall of a glass cup through a handle shell. During the installation process, two symmetric and oppositely joined and fixed handle covers need to clamp the handle while clamping the capacitive induction board, so as to realize the positioning of the capacitive induction board while fixing the handle shell, and ensure the relative position relationship between the capacitive induction board and the glass cup body. Although in this solution, the capacitive induction board and the glass cup body are in a relatively fixed relationship and there will be no displacement between them, in this structure, a handle needs to be provided on the glass cup body to position the handle shell, and then the capacitive induction board is fixed and limited through the positioning of the handle shell. Not only is the installation structure complex, but when there is an assembly error between the handle shell and the handle, it will cause the problem that the capacitive induction board cannot accurately detect the liquid level signal. Moreover, in existing food processors or health kettles, tubular glass is widely used, and it is impossible to integrally form a handle structure on the glass cup body. Therefore, the above solution cannot be applied to tubular glass cup bodies. Moreover, the induction board is a rigid board, and the peripheral wall of the glass cup body is generally arc-shaped. How to reliably and accurately position and install the rigid liquid level detection board on the outer wall of the arc-shaped glass cup has always been a difficulty for R & D engineers to apply the non-contact detection technology to the liquid level detection of kitchen appliances.

[0004] After further research, the applicant has previously filed an application with application number CN2024103319154, in which the detection plate is positioned on the outer wall of the glass body with the help of a positioning plate, and a receiving cavity for accommodating the detection plate is formed by enclosing the positioning plate and the peripheral wall of the glass body. The detection plate is reliably installed by pouring glue into the receiving cavity, which effectively solves the above-mentioned problem of reliably and accurately fixing the detection plate to the curved outer wall of the glass. Of course, the applicant is still conducting continuous research on how to facilitate the positioning of the detection plate and optimize the glue feeding process. Utility Model Content

By designing a simple installation structure and fixing the detection plate by glue filling, the technical problem that the detection plate is difficult to be reliably and accurately installed on the glass cup body is solved, and the detection plate and the positioning structure are clamped labor-savingly and reliably, and the installation is convenient.

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

[0007] The utility model provides a liquid heater that is easy to install, comprising a glass cup body and a strip-shaped detection plate for detecting liquid level in the air, the detection plate is vertically installed on the peripheral wall of the glass cup body, and also comprises a positioning bracket fixed on the outer side of the glass cup body, the edge of the positioning bracket has a surrounding edge protruding toward the glass cup body, the end face of the surrounding edge is tightly matched with the peripheral wall of the glass cup body, so that the positioning bracket and the peripheral wall of the glass cup body are enclosed to form a receiving cavity for receiving the detection plate, the detection plate divides the receiving cavity into an inner chamber located on one side of the glass cup body and an outer chamber located on one side of the positioning bracket, the surrounding edge comprises a first side surrounding edge and a second side surrounding edge arranged vertically, the detection plate has a first side end wall affixed to the first side surrounding edge and a second side end wall corresponding to the second side surrounding edge, the second side surrounding edge is provided with a protruding limiting portion, the detection board is clamped between the first side surrounding edge and the limiting portion, and a glue gap is provided between the second side end wall and the second side surrounding edge, and glue fills the outer cavity and the inner cavity through the glue gap to encapsulate the detection board.

[0008] The utility model provides a liquid heater which is convenient to install. By fixedly arranging a positioning bracket on the outer side of a glass cup body, an accommodating cavity for accommodating a detection board is formed by enclosing the positioning bracket and the peripheral wall of the glass cup body. The detection board divides the accommodating cavity into an inner cavity on one side of the glass cup body and an outer cavity on one side of the positioning bracket. The first side edge of the positioning bracket and the limiting part protruding from the second side edge are used to clamp the detection board to realize pre-positioning of the detection board. Then, a glue filling process is adopted to fill the accommodating cavity with glue. The glue can fill the outer cavity and the inner cavity through the glue passing gap between the second side end wall and the second side edge. After standing for a period of time, the detection board can be firmly fixed on the outer wall of the glass cup body to encapsulate the detection board, effectively solving the problem of fixing a rigid detection board on the outer wall of a curved glass cup in the prior art. Moreover, the first side edge and the second side edge also play a good role in protecting the detection board, and the end face of the side edge is tightly fitted with the peripheral wall of the glass cup body. During the process of filling the accommodating cavity with glue, the glue is not easy to overflow from the gap between the positioning board and the glass cup body, ensuring the effective utilization of the glue and solving the problems of difficult cleaning and glue waste after overflow. In addition, the first side end wall of the detection board is attached and limited to the first side edge, and the detection board is clamped by the limiting part and the first side edge. During the process of positioning the detection board and the positioning bracket, the operator can first use the first side end wall as a fulcrum, and then tilt the detection board into the positioning bracket. Only by adjusting the angle of the detection board so that the second side end wall of the detection board abuts against the limiting part can the contact area between the second side end wall and the positioning bracket be reduced on the premise of realizing reliable fixation of the detection board, so that the clamping of the detection board and the positioning bracket is more labor-saving and the operation is convenient. Moreover, through the glue passing gap between the second side end wall and the second side edge, the inner cavity and the outer cavity separated by the detection board are communicated. In this way, during the glue filling process, the glue can more quickly and comprehensively fill into the inner cavity and the outer cavity from the glue passing gap, and the glue flowing is smooth, so as to realize the encapsulation of the whole detection board and ensure the reliability of the positioning and fixation of the detection board.

Moreover, under the limiting action of the hollowed-out frame, the solidified glue can cover the detection board in a larger area, so as to achieve a good sealing effect.

[0011] In a preferred embodiment, the positioning bracket includes a cover plate that closes the accommodating cavity, and the cover plate is integrally formed with the surrounding edge.

[0012] The positioning bracket uses a cover plate to close the accommodating cavity, and glue can be injected through a separately provided glue inlet. During the glue injection process, it can prevent the glue from spilling out, causing waste and troublesome cleaning, and realize the effective utilization of the glue. In addition, the cover plate can block the outside of the detection plate, so that the detection plate is protected in a double layer through the glue injection layer and the cover plate.

[0013] In a preferred embodiment, the first side surrounding edge and the second side surrounding edge are arranged to be disconnected along the edge of the cover plate, and an opening for injecting glue into the accommodating cavity is formed between the ends of the first side surrounding edge and the second side surrounding edge.

[0014] By arranging the first side surrounding edge and the second side surrounding edge to be disconnected along the edge of the cover plate, an opening for injecting glue into the accommodating cavity is formed between the ends of the first side surrounding edge and the second side surrounding edge, which facilitates injecting glue into the outer cavity or the inner cavity, or injecting glue into the outer cavity and the inner cavity simultaneously, thus accelerating the fixing efficiency.

[0015] In a preferred embodiment, a pressing portion for pressing the detection plate against the glass cup body is provided on the side of the cover plate facing the glass cup body, and a glue channel is recessed on the pressing surface of the pressing portion, and the glue channel communicates the inner cavity with the outer cavity.

[0016] By providing a pressing portion on the cover plate, the detection plate can be pressed tightly against the glass cup body, reducing the volume of the accommodating cavity, making the structure compact, facilitating the close detection of the liquid level in the glass cup body by the detection plate, improving the detection accuracy, saving the glue injection amount, and realizing the reliable fixation of the detection plate.

A traditional glass cup body can be used without additional processing and modification, reducing processing costs. In addition, the detection plate abuts against the glass cup body to form a first inner cavity and a second inner cavity. The glue passing gap communicates the second inner cavity with the outer cavity. The glue can be filled in sequence through the glue passing gap, the communication groove or the glue passing hole, via the outer cavity, the second cavity and the first cavity to achieve the encapsulation of the detection plate.

[0020] In a preferred embodiment, the outer surface of the circumferential wall of the glass cup body is a curved surface concave towards the center of the glass cup body. The detection plate is located in the accommodation cavity and abuts tightly against the circumferential wall of the glass cup body.

[0048] like Figures 1-6 As shown, the utility model provides a liquid heater that is easy to install in one embodiment, including a glass cup body 10 and a strip-shaped detection plate 20 for detecting the liquid level in the air, wherein the detection plate 20 is vertically installed on the peripheral wall of the glass cup body 10, and further includes a positioning bracket 30 fixed to the outside of the glass cup body 10, wherein the edge of the positioning bracket 30 has a surrounding edge protruding toward the glass cup body 10, and the end surface of the surrounding edge is tightly matched with the peripheral wall of the glass cup body 10, so that the positioning bracket 30 and the peripheral wall of the glass cup body 10 are enclosed to form a receiving cavity 40 for receiving the detection plate 20, and the detection plate 20 divides the receiving cavity 40 into two parts located in the glass cup body 1 0 and an outer chamber 42 located on one side of the positioning bracket 30, the surrounding edge includes a first side surrounding edge 31 and a second side surrounding edge 32 arranged vertically, the detection board 20 has a first side end wall corresponding to the first side surrounding edge 31 and a second side end wall corresponding to the second side surrounding edge 32, the second side surrounding edge 32 is provided with a raised limiting portion 33, the detection board 20 is clamped between the first side surrounding edge 31 and the limiting portion 33, and a glue gap 34 is provided between the second side end wall and the second side surrounding edge 32, and the glue liquid fills the outer chamber 42 and the inner chamber 41 through the glue gap 34 to encapsulate the detection board 20.

[0049] A liquid heater that is convenient for installation provided by the present utility model forms an accommodation cavity 40 for accommodating a detection board 20 by fixedly arranging a positioning bracket 30 on the outer side of a glass cup body 10, so that the positioning bracket 30 and the peripheral wall of the glass cup body 10 enclose the accommodation cavity 40. The detection board 20 divides the accommodation cavity 40 into an inner cavity 41 on one side of the glass cup body 10 and an outer cavity 42 on one side of the positioning bracket 30. The first side edge 31 of the positioning bracket 30 and the limiting portion 33 protruding from the second side edge 32 are used to clamp the detection board 20 to realize the pre-positioning of the detection board 20. Then, a potting process is adopted to pot the glue into the accommodation cavity 40. The glue can fill the outer cavity 42 and the inner cavity 41 through the glue passing gap between the second side end wall and the second side edge 32. After standing for a period of time, the detection board 20 can be firmly fixed on the outer wall of the glass cup body 10 to encapsulate the detection board 20, effectively solving the problem of fixedly installing a rigid detection board 20 on the outer wall of a curved glass cup body 10 in the prior art. Moreover, the first side edge 31 and the second side edge 32 also have a good effect of protecting the detection board 20, and the end face of the side edge is tightly fitted with the peripheral wall of the glass cup body 10. During the process of potting the glue into the accommodation cavity 40, the glue is not easy to overflow from the gap between the positioning plate and the glass cup body 10, ensuring the effective utilization of the glue and solving the problems of difficult cleaning and glue waste after overflow. In addition, the first side end wall of the detection board 20 is fitted and limited with the first side edge, and the detection board 20 is clamped by means of the limiting portion and the first side edge. During the process of positioning the detection board 20 and the positioning bracket 30, the operator can first use the first side end wall as a fulcrum, and then tilt the detection board 20 and put it into the positioning bracket 30. Only by adjusting the angle of the detection board 20 so that the second side end wall of the detection board 20 abuts against the limiting portion. Therefore, on the premise of realizing the reliable fixation of the detection board 20, the contact area between the second side end wall and the positioning bracket 30 is reduced, so that the clamping of the detection board 20 and the positioning bracket 30 is more labor-saving and the operation is convenient. And through the glue passing gap between the second side end wall and the second side edge, the inner cavity and the outer cavity separated by the detection board 20 are communicated. In this way, during the potting process, the glue can fill the inner cavity and the outer cavity more quickly and comprehensively from the glue passing gap, and the glue flow is smooth, so as to realize the encapsulation of the entire detection board 20 and ensure the reliability of the positioning and fixation of the detection board 20.

[0050] The present utility model does not limit the shape of the positioning bracket 30. For example:

[0051] Embodiment 1, as Figures 1-6 shown, the positioning bracket 30 includes a cover plate that closes the accommodation cavity 40, and the cover plate and the side edge are integrally formed.

[0052] The positioning bracket 30 uses a cover plate to enclose the accommodation cavity 40. Glue can be poured through a separately provided glue inlet, preventing glue from spilling during the pouring process, which causes waste and troublesome cleaning, and realizing the effective utilization of the glue. In addition, the cover plate can block the outside of the detection plate 20, enabling the detection plate 20 to achieve double protection through the glue pouring layer and the cover plate.

[0053] Preferably, as Figure 3 shown, an opening 35 is provided through the cover plate to pour glue into the accommodation cavity 40.

[0054] As Figure 4 shown, the limiting part 33 is two limiting steps respectively located at both ends of the second side edge 32, and the glue passing gap is formed between the two limiting steps. Of course, the number of the limiting parts 33 provided in the present utility model is not limited to this.

[0055] In addition, in other embodiments, the first side edge 31 and the second side edge 32 can also be disconnected along the edge of the cover plate, and an opening for pouring glue into the accommodation cavity 40 is formed between the ends of the first side edge 31 and the second side edge 32. By disconnecting the first side edge 31 and the second side edge 32 along the edge of the cover plate to form an opening for pouring glue into the accommodation cavity 40 between the ends of the first side edge 31 and the second side edge 32, it is convenient to pour glue into the outer cavity 42 or the inner cavity 41, or pour glue into the outer cavity 42 and the inner cavity 41 at the same time, thus accelerating the fixing efficiency.

[0056] As Figure 5 shown, in this embodiment, preferably, a pressing part for pressing the detection plate 20 against the glass cup body 10 is provided on the side of the cover plate facing the glass cup body 10. The pressing part can be the inner side surface of the cover plate or a pressing rib protruding from the inner side surface. A glue running groove 36 is recessed in the pressing surface of the pressing part, enabling the glue to flow smoothly between the outer cavity 42 and the inner cavity. As Figure 5 shown, more preferably, the glue running groove 36 is arranged along the first side edge 31; of course, the glue running groove can also be arranged close to the second side end wall of the detection plate, and the glue running groove is communicated with the glue passing gap.

[0057] By providing a pressing part on the cover plate, the detection plate 20 can be pressed against the glass cup body 10, reducing the volume of the accommodation cavity 40, making the structure compact, facilitating the close-range detection of the liquid level in the glass cup body 10 by the detection plate 20, improving the detection accuracy, saving the glue pouring amount, and realizing the reliable fixation of the detection plate 20. It should be noted that the above-mentioned pressing part can also be applied to other embodiments.

[0058] In this embodiment, the liquid heater is a health kettle. Specifically, the outer surface of the peripheral wall of the glass body 10 is a curved surface protruding outward. The detection plate 20 is pressed against the peripheral wall of the glass body 10. The inner cavity 41 includes a first inner cavity and a second inner cavity separated by the pressed part of the detection plate 20 and the glass body 10. The glue passing gap communicates the second inner cavity with the outer cavity 42. More preferably, a sunken communication groove is provided on the inner side surface of the first side border 31, and the communication groove communicates between the first inner cavity and the outer cavity 42.

[0059] Actually, glue passing holes can also be penetrated through the detection plate 20, and the glue passing holes communicate between the first inner cavity and the outer cavity 42.

[0060] The outer surface of the peripheral wall of the glass body 10 is a curved surface protruding outward. A traditional glass body 10 can be used without additional processing and modification, reducing the processing cost. In addition, the detection plate 20 is in contact with the glass body 10 to form a first inner cavity and a second inner cavity. The glue passing gap communicates the second inner cavity with the outer cavity 42. The glue can pass through the glue passing gap, the communication groove or the glue passing hole, and is filled in sequence through the outer cavity 42, the second chamber and the first chamber to realize the encapsulation of the detection plate 20.

[0061] In addition, it should be noted that for the detection plate 20 of this embodiment, the detection plate 20 is provided with capacitor plates 21. The detection plate 20 can not only detect the water level signal but also detect the anti-overflow signal. Moreover, multiple capacitor plates can be provided on the detection plate 20 for detecting different anti-overflow positions. And for this embodiment, the changes in the above structure can also be applied to other embodiments of the present invention.

[0062] Embodiment 2, as Figure 7 、 Figure 8 shown, different from Embodiment 1, in this embodiment, the positioning bracket 30 includes a hollowed-out frame connecting the first side border 31 and the second side border 32. A hollowed-out opening 37 that opens the outer cavity 42 is formed on the hollowed-out frame, and glue is poured into the outer cavity 42 through the hollowed-out opening.

[0063] The positioning bracket 30 adopts a hollowed-out frame, and a hollowed-out opening that opens the outer cavity 42 is formed on the hollowed-out frame. The hollowed-out opening serves as a glue inlet, and glue is poured into the outer cavity 42 through the hollowed-out opening, which can accelerate the glue pouring process, save the glue pouring time, and improve the fixing efficiency of the detection plate 20. Moreover, under the limiting effect of the hollowed-out frame, the cured glue can cover the detection plate 20 in a larger area, thus achieving a good sealing effect.

[0064] In addition, the difference between this embodiment and Embodiment 1 is also that, as Figure 8As shown, the outer surface of the circumferential wall of the glass cup body 10 is a curved surface that is concave inward towards the center of the glass cup body 10. The detection plate 20 is located inside the accommodation cavity 40 and abuts against the circumferential wall of the glass cup body 10. An inner cavity 41 is formed between the detection plate 20 and the circumferential wall of the glass cup body 10, and the horizontal cross-section of the inner cavity 41 is crescent-shaped. More preferably, a recessed groove (not shown) is provided on the second side wall of the detection plate 20, and the groove communicates the glue-passing gap with the inner cavity 41.

[0065] The outer surface of the circumferential wall of the glass cup body 10 is a curved surface that is concave inward towards the center of the glass cup body 10, forming a groove for accommodating the glue. During the glue injection process, the glue can be more stably retained in the accommodation cavity 40, and then the detection plate 20 can be reliably positioned outside the glass cup body 10 after curing. By providing the groove, the glue-passing gap is communicated with the inner cavity 41, thereby accelerating the flow rate of the glue between the outer cavity 42 and the inner cavity 41, accelerating the efficiency of filling the installation cavity with the glue, and improving the assembly efficiency.

[0066] Of course, it can be understood that different forms of the glass cup body 10 and different forms of the positioning bracket 30 can be freely combined, not limited to the above combination method.

[0067] The present invention does not limit the fixing method between the positioning bracket 30 and the glass cup body 10. For example:

[0068] Embodiment 3, as Figures 9-11 shown, the top of the positioning bracket 30 has a hooking portion 301 that hooks on the rim of the glass cup body 10, and the positioning bracket 30 is pre-positioned on the glass cup body 10 through the hooking portion 301.

[0069] In addition, in this embodiment, the liquid heater is an integrated food processor with a motor at the bottom. The liquid heater includes a crushing knife 60 located inside the glass cup body and a motor 70 fixed to the bottom of the glass cup body to drive the crushing knife.

[0070] Preferably, a shielding member 50 for covering the positioning bracket 30 is provided on the outside of the positioning bracket 30. As Figure 10 、 11 shown, the shielding member 50 is a handle.

[0071] Of course, the shielding member can also be adjusted according to the form of the liquid heater. For example, when the liquid heater is an automatic water-inlet food processor that does not need to be hand-washed, the shielding member can be an operation panel. Or, when the liquid heater uses a double-layer cup body, the shielding member is a cup body shell sleeved outside the glass cup body 10, etc.

[0072] By setting the shielding member, the glue inlet opening on the positioning bracket 30 is prevented from being exposed, the possibility of dust, liquid or other sundries entering the accommodating cavity 40 is avoided, the detection board 20 is protected, and the overall visual effect is not affected due to the exposure of the glue inlet, and the appearance is more tidy and beautiful.

[0073] Embodiment 4: A cup base is fixed to the bottom of the glass cup body 10, and the bottom of the positioning bracket 30 has a pre-positioning structure that cooperates with the cup base; the pre-positioning structure is, for example, an insertion plate provided at the bottom of the positioning bracket 30, and a slot is provided in the cup base, and the insertion plate is inserted and cooperated with the slot.

[0074] Embodiment 5: Adhesive is provided on the end surface of the surrounding edge, and the positioning bracket 30 is fixed to the outer surface of the peripheral wall of the glass cup body 10 through the adhesive.

[0075] Whether by setting a hanging part at the top of the positioning bracket 30, or using a pre-positioning structure that cooperates with the cup base or adhesive at the bottom of the positioning bracket 30, the pre-positioning between the positioning bracket 30 and the glass cup body 10 can be achieved. After the glue injection is completed, the fixation between the detection board 20, the positioning bracket 30 and the glass cup body 10 can be directly completed. Of course, the above-mentioned hanging part, pre-positioning structure or adhesive can also be used to achieve a double reinforcement effect on the detection board 20, improve the connection strength of each part, and prevent problems such as loosening of the connection caused by the liquid heater falling.

[0076] It should be noted that the liquid heater of the present invention is not limited to the above-mentioned health preservation kettle and integrated food processor. The liquid heater can also be a soymilk machine with a motor placed on top, a wall breaker with a separable cup body and machine base, and a hands-free food processor that can achieve automatic pulp discharge and automatic cleaning. In addition, the liquid heater can also be applied to heating appliances for making beverages such as soymilk cooking and rice paste making, such as a boiling water pot and a health preservation pot.

[0077] In the present invention, the parts not described can be realized by adopting or referring to the existing technologies.

[0078] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments.

[0079] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
