Description

Technical Field

[0001] The utility model relates to, in particular to, a liquid heater. Background Art

[0002] Existing liquid heaters, such as electric kettles, boiling water kettles, health kettles, etc., generally include a glass kettle body and a liquid level detection component arranged on the outside of the glass kettle body. The liquid level detection component includes a detection plate for air-to-air detection and a mounting bracket attached to the glass kettle body. The mounting bracket encloses a receiving space, and the detection plate is placed in the receiving space. In order to increase the service life of the detection plate, sealant will be filled in the receiving space to encapsulate the detection board. The sealant is not easy to flow and will affect the packaging efficiency. Therefore, in order to improve the packaging efficiency, connecting ribs will be provided on the mounting bracket to divide the receiving space into multiple glue filling grooves. At the same time, the connecting ribs are designed to be located on the surface of the detection plate facing away from the glass kettle body to limit the detection plate from being away from the glass kettle body, which is also beneficial to improve the structural strength of the mounting bracket. However, after the glue filling grooves are increased, each glue filling groove needs to be filled with glue, and the sizes of the glue filling grooves cannot be completely consistent. The amount of sealant added to each glue filling groove varies, and uneven thickness is likely to occur. Moreover, after filling one glue filling groove, adding sealant to another glue filling groove requires crossing the connecting ribs. Therefore, it is necessary to avoid the sealant dripping onto the connecting ribs. When passing the connecting ribs, it is necessary to make sure to stop adding sealant. The process of adding sealant will become intermittent, which is very inconvenient to operate, affecting the efficiency of adding sealant, and thus affecting the packaging efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a liquid heater to solve the problem that the thickness of sealant in different glue filling grooves is uneven and affects the packaging efficiency, ensure the continuity of adding sealant, and make the thickness of sealant in different glue filling grooves more uniform.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a liquid heater, comprising a glass kettle body and a liquid level detection component arranged on the outside of the glass kettle body, the liquid level detection component comprising a detection plate for air-to-air detection and a mounting bracket attached to the glass kettle body, the mounting bracket enclosing a accommodating space, the detection plate being placed in the accommodating space, the sealant being filled in the accommodating space to encapsulate the detection plate, the mounting bracket being provided with connecting ribs which divide the accommodating space into a plurality of glue filling grooves, the connecting ribs being located on the surface of the detection plate facing away from the glass kettle body to limit the detection plate from being away from the glass kettle body, the surface of the connecting rib away from the glass kettle body being provided with a circulation groove, the two ends of the circulation groove being connected to the glue filling grooves on both sides of the connecting rib, and the sealant flowing balance between different glue filling grooves through the circulation grooves.

[0005] After adopting the above technical scheme, the utility model has the following advantages: the sealant flows evenly between different glue filling grooves through the circulation groove, so that the sealant thickness of different glue filling grooves can be more uniform. At the same time, since the purpose of the design of the circulation groove is to allow the sealant to flow, when adding sealant, the moving path of the container storing the sealant can be from one glue filling groove to another glue filling groove through the circulation groove. The sealant can keep flowing out of the container. The moving speed can be appropriately increased through the glue filling groove. The process of adding sealant will become a continuous state, which is more convenient to operate. The sealant will not drip onto the parts of the connecting rib where sealant is not desired (parts of the non-circulation groove). Firstly, the efficiency of adding sealant can be improved, secondly, unnecessary waste of sealant can be reduced, and thirdly, the packaging effect can be ensured to be consistent and stable.

[0006] Furthermore, the connecting ribs are arranged transversely so that the glue pouring grooves are arranged longitudinally, or are arranged longitudinally so that the glue pouring grooves are arranged transversely.

[0007] The above technical solution is adopted, and the structure is simple and effective.

[0008] Furthermore, a flow groove is provided on each connecting rib so that all the glue pouring grooves form a single-line connected state, or two flow grooves are provided on each connecting rib so that all the glue pouring grooves form a loop connected state.

[0009] By adopting the above-mentioned technical solution, the container for storing sealant can continuously and quickly add sealant to each glue filling groove, which is not only convenient for manual operation but also conducive to automatic addition of sealant.

[0010] Furthermore, the connecting rib includes a first rib body arranged transversely and a second rib body arranged longitudinally, the glue pouring grooves are distributed along the height direction and the circumferential array of the glass pot body, and the flow grooves are arranged on the first rib body and the second rib body so that all the glue pouring grooves form a single curve connection state or a loop connection state.

[0011] By adopting the above-mentioned technical solution, the first rib and the second rib are connected to form a grid structure, which can improve the structural strength of the mounting bracket, improve the limiting effect of the detection plate, and reduce the adverse effects on the structural strength of the connecting rib caused by the setting of the flow groove.

[0012] Furthermore, the connecting rib includes a first rib body arranged transversely and a second rib body arranged longitudinally, at least two glue pouring grooves are distributed side by side along the height direction of the glass pot body and are arranged in sequence with other glue pouring grooves along the height direction of the glass pot body, and the flow grooves are arranged on the first rib body and the second rib body so that all the glue pouring grooves form a single curve connection state or a loop connection state; or, the connecting rib includes a first rib body arranged transversely and a second rib body arranged longitudinally, at least two glue pouring grooves are distributed side by side along the circumference of the glass pot body and are arranged in sequence with other glue pouring grooves along the circumference of the glass pot body, and the flow grooves are arranged on the first rib body and the second rib body so that all the glue pouring grooves form a single curve connection state or a loop connection state.

[0013] By adopting the above-mentioned technical solution and increasing the distribution of the glue filling slots, a variety of adaptation solutions can be provided according to actual needs.

[0014] Furthermore, the connecting rib includes a first rib body arranged transversely and a second rib body arranged longitudinally, and the flow groove is provided in the first rib body and / or the second rib body.

[0015] Furthermore, both ends of the first rib are connected to the mounting bracket or the second rib; or, one end of the first rib is connected to the mounting bracket, and the other end is connected to the second rib.

[0016] Furthermore, both ends of the second rib are connected to the mounting bracket or the first rib; or, one end of the second rib is connected to the mounting bracket, and the other end is connected to the first rib.

[0017] Furthermore, the second rib is located on the longitudinal symmetry line of the mounting bracket, the surface of the second rib away from the glass pot body is higher than the surface of the mounting bracket away from the glass pot body, one end of the first rib is connected to the mounting bracket, and the other end is connected to the second rib, and the surface of the first rib away from the glass pot body extends obliquely from the second rib to the mounting bracket.

[0018] By adopting the above-mentioned technical solution, the strength of the position where the second rib is located is better, and at the same time, the sealant will also change in thickness along the height of the first rib under the action of tension, that is, the thickness is larger near the second rib, and the thickness is smaller near the mounting brackets on both sides. The encapsulated structure forms a structure that is relatively far away from the outer side of the glass pot body in the middle and inclined close to the glass pot body on both sides. If water flows onto the liquid level detection component, it will not remain.

[0019] Furthermore, the mounting bracket includes two first brackets extending along the height direction of the glass pot body and a second bracket connected between the two first brackets, and the first bracket and the second bracket enclose an accommodating space;

[0021] By adopting the above-mentioned technical solution, the sealant has a certain shock-absorbing effect. After filling the gap between the side of the detection plate and the mounting bracket (side flow gap and / or end flow gap) with sealant, the rigid contact between the mounting bracket and the detection plate can be reduced, which is conducive to the flexible fixation of the detection plate and ensures reliability in long-term use.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0038] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0039] like Figures 1 to 5As shown, the present invention provides a liquid heater, including a glass kettle body 100 and a liquid level detection assembly arranged on the outside of the glass kettle body 100. The glass kettle body 100 generally includes a kettle body made of glass material and a heating plate at the bottom (not shown). A kettle lid is installed on the top of the kettle body, and the heating plate seals the opening at the bottom of the kettle body. These belong to the existing technology and are not described in detail. The liquid level detection assembly includes a detection plate 200 for air detection and a mounting bracket 300 attached to the glass kettle body 100. The detection plate 200 for air detection is also an existing technology, which usually uses the capacitance value of the sensing electrode piece caused by the change of water level. The water level detection is realized by the change, which will not be described in detail here. In order to obtain long-term reliability of the detection board 200 after installation and to facilitate packaging, the mounting bracket 300 is surrounded by a receiving space, the detection board 200 is placed in the receiving space, and the sealant 400 is filled in the receiving space to encapsulate the detection board 200. The mounting bracket 300 can not only constrain the detection board 200, but also constrain the sealant 400. The mounting bracket 300 is provided with a connecting rib 31 that divides the receiving space into a plurality of glue filling grooves 301. The connecting rib 31 is located on the surface of the detection board 200 facing away from the glass pot body 100 to limit the detection board 20 0 is away from the glass pot body 100. In order to further improve the packaging efficiency, a circulation groove 32 is provided on the surface of the connecting rib 31 away from the glass pot body 100. The two ends of the circulation groove 32 are connected to the glue pouring grooves 301 on both sides of the connecting rib 31. The sealant 400 flows evenly between different glue pouring grooves 301 through the circulation groove 32, which can make the thickness distribution of the sealant 400 in different glue pouring grooves 301 more uniform. At the same time, since the purpose of the design of the circulation groove 32 is to allow the sealant 400 to flow, the moving path of the container storing the sealant 400 can be adjusted when adding the sealant 400. When passing from one glue filling groove 301 through the circulation groove 32 to another glue filling groove 301, the sealant 400 can keep flowing out of the container. By appropriately increasing the moving speed through the glue filling groove 301, the process of adding the sealant 400 will become a continuous state, which is more convenient to operate. The sealant 400 will not drip onto the parts of the connecting rib 31 where the sealant 400 is not desired (the parts of the non-circulation groove 32). Firstly, the efficiency of adding the sealant 400 can be improved, secondly, unnecessary waste of the sealant 400 can be reduced, and thirdly, the packaging effect can be ensured to be consistent and stable.

[0040] In this embodiment, the connecting rib 31 includes a first rib body 311 arranged horizontally and a second rib body 312 arranged longitudinally. Some glue pouring grooves 301 are arranged in an array along the height direction of the glass pot body 100 and the circumference of the glass pot body 100. At the same time, there is another glue pouring groove 301 at the bottom and arranged in an array with the glue pouring grooves 301 arranged above. The flow groove 32 is provided on the first rib body 311 and the second rib body 312 so that all the glue pouring grooves 301 form a loop connection state, that is, Figure 2As shown by the middle dotted line, the moving path of the container storing the sealant 400 can move along the dotted line, and the sealant 400 can be added to each glue filling groove 301 continuously and quickly, which is not only convenient for manual operation, but also conducive to automatic addition of the sealant 400.

[0041] Regarding the structure of the connecting rib 31, the first rib 311 can be connected to the mounting bracket 300 at both ends, or one end of the first rib 311 can be connected to the mounting bracket 300 and the other end to the second rib 312, or even both ends of the first rib 311 can be connected to the second rib 312. Similarly, the second rib 312 can be connected to the mounting bracket 300 or the first rib 311 at both ends, or one end of the second rib 312 can be connected to the mounting bracket 300 and the other end to the first rib 311. The connection between the first rib 311 and the second rib 312 can form a grid structure, which improves the structural strength of the mounting bracket 300, enhances the limiting effect of the detection plate 200, and reduces the adverse effect on the structural strength of the connecting rib 31 caused by the provision of the flow groove 32.

[0042] In one embodiment, the length of the detection plate 200 is much larger than the width, that is, the size of the detection plate 200 in the height direction of the glass pot body 100 is much larger than the size in the circumferential direction. Therefore, more limits are required in the height direction of the glass pot body 100, so the length of the mounting bracket 300 is much larger than the width, and the number of the first ribs 311 is more than the number of the second ribs 312. It can be understood that if the size of the detection plate 200 in the circumferential direction of the glass pot body 100 is much larger than the size in the height direction, then the number of the second ribs 312 can be increased accordingly, and the number of the first ribs 311 can be reduced. Based on the small number of the second ribs 312, the second ribs 312 can be selected to be located on the longitudinal symmetry line of the mounting bracket 300, and the mounting bracket 300 can form a left-right symmetrical structure. The volume of the glue filling groove 301 can be equal or similar, which is convenient for quantitative addition of sealant 400. The surface of the second rib 312 away from the glass pot body 100 is higher than the surface of the mounting bracket 300 away from the glass pot body 100. One end of the first rib 311 is connected to the mounting bracket 300, and the other end is connected to the second rib 312. Since the center position on the mounting bracket 300 needs to limit the detection plate 200, the surface of the first rib 311 away from the glass pot body 100 can be designed to extend obliquely from the second rib 312 to the mounting bracket 300, that is, the strength at the position of the second rib 312 is better. At the same time, the sealant 400 will also change in thickness along the height change of the first rib 311 under the action of tension, that is, the thickness is large near the second rib 312, and the thickness is small near the mounting brackets 300 on both sides. Figure 3As shown, the packaged structure forms a structure in which the middle is relatively far away from the outer side of the glass pot body 100 and the two sides are inclined close to the glass pot body 100. If water flows onto the liquid level detection component, no residue will remain.

[0043] The structure of the mounting bracket 300 is also affected by the shape of the detection plate 200. For example, the detection plate 200 in this embodiment is a rectangular structure, and the corresponding design of the mounting bracket 300 includes two first brackets 33 extending along the height direction of the glass pot body 100 and a second bracket 34 connected between the two first brackets 33. The first bracket 33 and the second bracket 34 enclose an accommodating space; and in order to improve the packaging effect, it can be combined with Figure 4 and Figure 5 As can be seen, a side flow gap 302 for the sealant 400 to pass through is provided between the first bracket 33 and the longitudinal side of the detection plate 200. The side flow gap 302 connects the accommodation space of the detection plate 200 facing the glass pot body 100 with the accommodation space facing away from the glass pot body 100. Similarly, an end flow gap 303 for the sealant 400 to pass through can be provided between the second bracket 34 and the transverse side of the detection plate 200. The end flow gap 303 connects the accommodation space of the detection plate 200 facing the glass pot body 100 with the accommodation space facing away from the glass pot body 100. The sealant 400 has a certain shock-absorbing effect. After the gap between the side of the detection plate 200 and the mounting bracket 300 (the side flow gap 302 and / or the end flow gap 303) is filled with the sealant 400, the rigid contact between the mounting bracket 300 and the detection plate 200 can be reduced, which is beneficial to the flexible fixation of the detection plate 200 and ensures reliability in long-term use.

[0044] like Figure 6 As shown, in another embodiment, the connecting rib 31 can be designed to include only the first rib body 311 arranged horizontally, without the second rib body 312, so that the glue pouring grooves 301 are arranged vertically. In order to facilitate glue pouring, a flow groove 32 can be provided on each connecting rib 31 so that all the glue pouring grooves 301 form a single curved connection state ( Figure 6 (shown by the dashed line), or Figure 7 As shown, two flow grooves 32 are provided on each connecting rib 31, forming a looped connection between all the glue filling grooves 301. Alternatively, the connecting rib 31 may include only the longitudinally arranged second rib 312, without the first rib 311, so that the glue filling grooves 301 are arranged transversely, for example, when the transverse dimension of the test board 200 is greater than the longitudinal dimension.

[0045] like Figure 8As shown, in another embodiment, the connecting rib 31 includes a first rib body 311 arranged horizontally and a second rib body 312 arranged longitudinally. The glue pouring grooves 301 are distributed along the height direction and the circumference direction of the glass pot body 100, for example, in a 2X4 form. The flow grooves 32 are provided on the first rib body 311 and the second rib body 312 so that all the glue pouring grooves 301 form a loop connection state. Figure 9 As shown, all the glue filling grooves 301 form a single curved line connection state, so it can be understood that the single curved line connection state is not limited to a straight line, and can also be a curve.

[0046] like Figure 10 As shown, in another embodiment, the connecting rib 31 includes a first rib 311 arranged transversely and a second rib 312 arranged longitudinally. Even if the longitudinal dimension of the detection board 200 is much larger than the transverse dimension, the number of the first ribs 311 can be consistent with the number of the second ribs 312. The two glue pouring grooves 301 are distributed side by side along the height direction of the glass pot body 100 and are arranged in sequence with other glue pouring grooves 301 in the height direction of the glass pot body 100. In fact, the number of glue pouring grooves 301 distributed side by side along the height direction of the glass pot body 100 can be increased as needed. For example, three glue pouring grooves 301 can be arranged side by side and then arranged in sequence with one or two or four or more glue pouring grooves 301 in the height direction of the glass pot body 100. In short, some simple deformations can be made according to actual needs. Figure 11 As shown, the individual glue pouring grooves 301 can also be at both ends of the glue pouring grooves 301 arranged side by side, and there is a glue pouring groove 301 above and below the two glue pouring grooves 301 arranged side by side, and both can form a loop connection state as shown by the dotted line. Of course, a single curved connection state can also be selected. It is understandable that at least two glue pouring grooves 301 can also be arranged side by side along the circumference of the glass pot body 100 and arranged in sequence with other glue pouring grooves 301 along the circumference of the glass pot body 100. The flow grooves 32 are provided on the first rib 311 and the second rib 312 so that all the glue pouring grooves 301 form a single curved connection state or a loop connection state, which is equivalent to Figure 10 or Figure 11 Rotate 90 degrees. This type will no longer be described with accompanying drawings.

[0047] In addition to the above distribution rules, the glue filling groove 301 can also be staggered, such as Figure 12 As shown, in another embodiment, the glue pouring grooves 301 are arranged side by side and staggered along the height direction of the glass pot body 100, and the flow grooves 32 are provided on the first rib 311 and the second rib 312 so that all the glue pouring grooves 301 form a single curved connection state. Of course, it can also be formed as shown in FIG. Figure 13 The loop connection status is shown.

[0048] After the glue potting grooves 301 are set on the first rib 311 and the second rib 312, their structural strength will be affected. Therefore, the number of glue potting grooves 301 is minimized, and it is not necessary to set a glue potting groove 301 on each first rib 311 and the second rib 312. At the same time, no matter what distribution form the glue potting grooves 301 adopts, as long as they can form a single curve connection state or a loop connection state, it can ensure the structural strength of the connecting rib 31 and facilitate packaging.

[0049] In addition to being arranged longitudinally or transversely, the connecting ribs 31 may also be arranged obliquely, and the mounting bracket 300 may also adopt a circular ring structure or other structure that is adapted to the shape of the detection board 200 .

[0050] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
