Description

Technical Field

[0001] The utility model relates to the technical field of teapots, in particular to a waterproof teapot base. Background Art

[0002] Most current teapots use electric heating to make tea. Such teapots involve a circuit board. If water (such as tea water) drips onto the circuit board built into the base of the teapot during use, it will affect the circuit board. Seriously, it may burn out the circuit board and even cause safety accidents such as fires. Therefore, waterproofing is required.

[0003] A teapot includes a pot body and a base for placing the pot body. The circuit board is usually built into the base. A teapot generally needs to be provided with a display component for indicating the working state of the base. For example, whether it is heating to make tea. The display component is generally installed on the surface of the base, and there is a gap between the display component and the surface of the base. The water inside the pot body boils after heating, and the boiling water will splash out and drip onto the base. The water dripping onto the base will flow into the inside of the base from the gap, and then the water will come into contact with the circuit board inside the base, thus causing damage to the circuit board. Seriously, it may cause a fire. Therefore, generally, the base needs to be waterproof designed.

[0004] Some existing teapot bases do not have a waterproof function. Although some other teapot bases have a waterproof function, the waterproof structure design is relatively complex, involving many components and high costs. Or simply by using the law of "water flowing to lower places" to set corresponding high and low surfaces on the teapot base, the waterproof effect of this structure is poor, and it is often impossible to completely avoid the situation of water splashing. The splashed water still will contact the circuit board. Therefore, a base with good waterproof performance including the situation of water splashing is needed. Summary of the Utility Model

Specific Embodiment

[0029] The following further describes the present utility model in conjunction with the accompanying drawings and specific implementation schemes:

[0030] As Figures 1-10 shown, a waterproof teapot base includes a chassis base 1, a drainage component, and a working component. The chassis base 1 includes a panel and a bottom cover 9 that are closed together, and a cavity is formed between the panel and the bottom cover 9. A circuit board 13 is arranged in the cavity. A groove is recessed on the panel, and the groove does not penetrate the panel. The working component is snap-fitted in the groove, so that the working component is detachably installed at the upper end of the chassis base 1, so that the working component can be removed when needed (such as for maintenance and replacement). There is a drainage gap 14 between the working component and the inner wall of the groove of the groove. Specifically, the working component is installed in the groove, and the drainage gap 14 is formed between the outer edge of the working component and the inner wall of the groove of the groove. Refer to Figure 8 , a drainage gap 14 is formed between the working component and the inner wall of the groove of the groove.

[0031] During actual use, the working component can be any one of the display component 2, the function button, or other physical components. The other physical components can be physical components for decoration. The waterproof teapot base can achieve waterproofing when there is a gap between the working component thereon and the inner wall of the groove of the groove, and does not limit the specific functions and effects of the working component. The display component 2 can be an indicating component or a working component with other functions (such as a function button). A drainage gap 14 is formed between the working component and the inner wall of the groove of the groove. The indicating component is used to indicate the working state of the teapot base, and the indicating component can be indicated by means of light. The display component 2 includes a light-transmitting plate and a light-transmitting indicator piece 6 that are light-transmitting. The light-transmitting plate is made of a transparent plastic sheet. The light-transmitting indicator piece 6 has a number of patterns and / or characters. Different patterns have different indicating meanings through light irradiation, so as to play an indicating role. For example, the light-transmitting indicator piece 6 is engraved with characters such as 85 °C, 100 °C, warm water, and slow fire. The light irradiation to the corresponding characters indicates that the waterproof teapot base is in the corresponding working state. For example, when the light shines on 85 °C and becomes bright, it means that the current waterproof teapot base heats the water temperature in the teapot thereon to 85 degrees Celsius.

[0032] The upper end surface of the display assembly 2 is flush with the surface of the panel, or the upper end surface of the display assembly 2 is slightly higher than the surface of the panel, so that water can flow into the drainage gap 14 better.

[0033] Among them, the drainage component passes through the circuit board 13 from top to bottom, or bypasses the circuit board 13 from one side and extends to the bottom of the chassis seat 1 to communicate with the outside, or is located above the circuit board 13 and extends toward the side wall of the chassis seat, and then directly communicates with the outside of one side of the chassis seat 1. For example, the drainage component extends directly toward the side of the panel above the circuit board 13 and communicates with the outside, so that water is discharged to the outside of the chassis seat through the drainage component, and the water will not contact the circuit board 13, thereby achieving the purpose of waterproofing.

[0034] A drainage gap 14 allowing water to flow is formed between the display component 2 and the inner wall of the groove. The drainage component includes a water guide column 15. The water guide column 15 is protruding from the side of the panel facing the cavity. The interior of the water guide column 15 is connected to the groove. The water guide column 15 and the panel are an integral structure to avoid water leakage caused by a gap at the connection between the water guide column 15 and the panel.

[0035] A drainage hole is provided inside the water guide column 15 which runs through the water guide column 15. The interior of the groove is connected to the water inlet of the drainage hole. The water outlet of the drainage hole is located on the side of the circuit board away from the panel. The water outlet of the drainage hole is connected to the outside of the chassis seat. The water inlet and the water outlet are located at opposite ends of the drainage hole.

[0036] In this example, the bottom cover 9 is provided with a water outlet 10 connected to the cavity and the outside of the bottom cover 9, and the water outlet of the drainage hole is connected to the water outlet on the bottom cover 9 so that the drainage hole is connected to the water outlet. The outside of the bottom cover 9 is also the outside of the chassis base 1. That is, the drainage component includes a water outlet, which is connected to the water outlet 10, and one end of the drainage component having the water outlet passes through the bottom of the bottom cover from the cavity 9 and extends to the outer periphery of the chassis base 1.

[0037] It is understandable that when the drainage volume is too large, water leakage is easy to occur at the position where the water guide column 15 is connected to the water outlet 10. In this regard, a water guide sleeve (not shown in the figure) is protruding from the bottom cover 9 toward the water outlet 10, and the water guide sleeve is provided with a first water guide groove (not shown in the figure) connected to the water outlet 10. One end of the water guide column 15 with a water outlet is inserted into the first water guide groove, so that the water discharged from the water outlet can be buffered by the first water guide groove.

[0038] In another example, the bottom cover 9 is provided with a water outlet hole 10 communicating with the cavity and the outside of the bottom cover 9. The water outlet of the drain hole is located directly above the water outlet hole 10. In this case, the water outlet of the drain hole can also communicate with the outside of the bottom cover 9. As long as it can ensure that the water flowing out of the water outlet of the drain hole can flow to the outside of the bottom cover 9, that is, it can ensure that the water flowing out of the water outlet of the drain hole can flow to the outside of the chassis base 1.

[0039] In one example, one end of the water guiding column 15 with a water outlet passes through the bottom cover 9 from inside the cavity and extends to the outside of the chassis base 1. In this case, the water inside the drain hole can be directly discharged to the outside of the chassis base 1 to achieve the drainage function.

[0040] The bottom cover 9 is also provided with a heat dissipation grille 11, and the heat generated when the circuit board 13 works can be dissipated through the heat dissipation grille 11.

[0041] Reference Figure 9 , in an alternative embodiment, two or more water guiding columns 15 are provided on the panel, and the water guiding columns 15 are spaced apart. Communication holes are provided on the groove side wall and / or the groove bottom. The drain holes in the water guiding columns 15 communicate with the inside of the groove through the communication holes. More preferably, the communication holes are provided at the bottom of the groove to drain the water in the groove as much as possible. In this example, there are three water guiding columns 15 and three communication holes. The three communication holes are spaced apart at the bottom of the groove, and the communication holes correspond to the water guiding columns 15 one by one. Setting three water guiding columns 15 in this way can drain the water from the groove faster and in time. Of course, in other examples, the number of water guiding columns 15 can also be set to one, two, four or five, etc. When there are two or more water guiding columns 15, two or more water guiding columns 15 can share a through hole.

[0042] In an alternative embodiment, the light-transmitting plate includes a plate body 21 and a buckle member. The plate body 21 is a waterproof plate. The buckle member is used for buckling with the inner wall and / or the bottom of the groove. The buckle member protrudes from one side of the plate body 21. Buckle positions are provided on the panel, and the buckle member is engaged with the buckle positions. More specifically, the buckle member is fixedly provided at the lower edge of the plate body 21 and extends towards the groove. The plate body 21 is light-transmitting, for example, made of glass or transparent glass.

[0043] Preferably, the buckle member includes a convex column 22 and a step 23 provided on the convex column 22. The step 23 protrudes outwardly on the outside of the convex column 22. The step 23 includes a buckling surface 231 and a smooth surface 232. The buckling surface 231 is a horizontal plane, and the smooth surface 232 is an inclined slope inward. The convex column 22 is vertically fixed at the lower edge of the plate body 21. In this example, the buckle member is buckled in the communication hole, so as to realize the snap connection between the display component 2 and the groove.

[0044] The water guiding column 15 includes a bottom panel 51, partition strips 53 and through holes 54. The through holes 54 serve as the drainage holes. The through holes 54 penetrate from the top end to the bottom end of the water guiding column 15. The water guiding column 15 penetrates the bottom of the groove, so that the water through holes 54 also penetrate the bottom of the groove. The bottom panel 51 is located on one side of the through hole 54 and is fixed on the side wall surface of the through hole 54. One or more partition strips 53 are provided. When multiple partition strips 53 are provided, two adjacent partition strips 53 are arranged in parallel at intervals. The upper and lower ends of the partition strips 53 are respectively fixed on the side wall and the bottom panel 51. The partition strips 53 are arranged obliquely outwards. A space of a certain size is formed between two adjacent partition strips 53 and the bottom panel 51, and this space is the grid-shaped snap grid 52. The snap grid 52 serves as a glue reduction hole, which can prevent the panel 51 from deforming when being snapped into the snap position in the snap grid 52 during the processing of the snap position.

[0045] When the display component 2 is snapped into the groove, the step 23 is snapped (i.e., buckled) onto the bottom panel 51. The snap surface 231 of the step 23 is located at the lower end of the bottom panel 51 and fits against the lower surface of the bottom panel 51, thereby snapping the step 23 onto the bottom panel 51. The outer wall of the convex column 22 abuts against the outer surface of the bottom panel 51.

[0046] Among them, the smooth surface 232 enables the step 23 to cross the bottom panel 51 more smoothly, so as to buckle the snap surface 231 onto the lower surface of the bottom panel 51. While the partition strips 53 play a role in strengthening the strength, they can also further buffer the water flowing slowly along the drainage gap 14, and the water passes along the inner wall of the through hole 54 and the space, and finally the water slowly flows out from the through hole 54, avoiding the water dropping directly from the through hole 54 quickly and touching the bottom cover 9 below, avoiding splashing water, and better protecting the circuit board 13.

[0047] The snap member and the board body 21 are of an integral structure, and the convex column 22 and the step 23 are of an integral structure.

[0048] In an alternative embodiment, a boss 7 is further provided in the groove. The upper end of the boss 7 protrudes from the bottom of the groove. A plurality of light-transmitting holes 12 are provided on the boss 7. The light-transmitting holes 12 vertically penetrate through the boss 7, so that the light-transmitting holes 12 communicate with the cavity. The light-transmitting holes 12 are directly above the LED lamp beads provided on the circuit board 13, and the light emitted by the LED lamp beads can just pass through the light-transmitting holes 12, thereby emitting a light prompt, such as indicating that the teapot is working or in a standby state. A light-transmitting indicating piece 6 is provided at the upper end of the boss 7. In this example, the light-transmitting indicating piece 6 is adhered to the upper surface of the boss 7. Information related to the working state of the teapot is provided on the light-transmitting indicating piece 6. For example, text information such as water temperature, switch state, and heat level is provided to display the corresponding text through the light-transmitting brightness, so that consumers can know the current working state of the teapot.

[0049] Of course, in practical applications, the light-transmitting holes 12 can also obliquely penetrate through the boss 7, as long as the light emitted by the LED lamp beads on the circuit board 13 can irradiate out from the light-transmitting holes 12 and then irradiate onto the light-transmitting indicating piece 6.

[0050] There is a gap between the boss 7 and the inner wall of the groove, so that a second water guide groove 4 is formed between the boss 7 and the inner wall of the groove. The inside of the water guide column 15 communicates with the second water guide groove 4. This design enables the water flowing into the groove to flow into the water guide column 15 along the second water guide groove 4, which is beneficial for drainage.

[0051] In an alternative embodiment, three water guide columns 15 are provided. Each water guide column 15 is provided with a drainage hole, and a total of three drainage holes are included. The three drainage holes are all located in the second water guide groove 4 between the inner wall of the groove and the boss 7, and the three drainage holes all have water inlets and water outlets. Refer to Figure 2 、 Figure 4 , a drainage hole is provided at the middle position on one side of the boss 7, and one drainage hole is provided on each side of both ends of the boss 7. The water inlets of the three drainage holes are respectively denoted as the first water inlet 3, the second water inlet 5, and the third water inlet 8.

[0052] In an alternative embodiment, a plurality of outwardly protruding support feet 16 are fixedly installed on the bottom cover 9. The support feet 16 are distributed at different positions on the bottom cover 9. In order to better balance the support chassis 1, at least two support feet 16 are provided on the bottom cover 9. The support feet 16 play a supporting role when the teapot is placed on an object surface (such as a tabletop). At the same time, the support feet 16 also play a role in separating the bottom cover 9 of the teapot from the object surface to form a height difference, preventing the water discharged from the water outlet hole 10 on the bottom cover 9 from flowing back into the cavity of the bottom cover due to excessive accumulation, causing the circuit board 13 to come into contact with water, and playing a waterproof role.

[0053] Wherein, a protective pad is further installed at one end of the supporting foot 16 away from the bottom cover 9, and the protective pad can prevent the kettle from slipping on the surface of an object and scratching the surface of the object.

[0054] During actual use, when water spills, for example, during the process of making tea, the tea in the teapot accidentally spills onto the panel on the chassis base 1, and the water flows into the groove along the drainage gap 14. The water on the panel first flows into the drainage gap 14, and the water in the drainage gap 14 flows towards the water guiding column 15, and then flows into the through hole 54 and flows out. The water flowing out of the through hole 54 finally flows through the water outlet hole 10 on the bottom cover 9 and is discharged to the outside of the chassis base 1. During the entire flow process of the water, it will not come into contact with the circuit board 13, thereby protecting the circuit board 13 and achieving the waterproof effect.

[0055] The waterproof effect of the utility model is good, which can effectively prevent water from contacting the circuit board 13 and can well protect the circuit board 13. In addition, the utility model has a simple structure, low cost and is convenient to maintain.

[0056] The embodiments disclosed in this specification are only an illustration of the unilateral features of the utility model. The protection scope of the utility model is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of the utility model. For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the utility model.
