These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here, for example.

[0032] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0033] The electric water heater of the related technology includes a barrel in an outer shell and an anti-electricity wall cover. The anti-electricity wall cover is provided with a display screen for displaying temperature, water consumption or other data that needs to be displayed. A plurality of buckles are provided on the inner wall of the anti-electricity wall cover and on one side of the anti-electricity wall cover. A plurality of claws are provided on the inner wall of the anti-electricity wall cover and on the other side of the anti-electricity wall cover. The buckles are used to locate the position of the anti-electricity wall cover, and the claws are used to achieve the installation and fixation of the anti-electricity wall cover and the barrel in the outer shell. When the anti-electricity wall cover needs to be installed, the claws need to be matched with the slots on the barrel in the outer shell first, and then the buckles need to be matched with the mounting holes on the barrel in the outer shell, and finally the bolts are screwed in to achieve the installation and fixation of the anti-electricity wall cover.

[0034] However, when installing the anti-electricity wall cover, not only the claws and the slots need to be matched, but also the buckles and the mounting holes need to be matched, which makes it inconvenient to install the anti-electricity wall cover; and when the claws, slots and buckle mounting holes are used to install the anti-electricity wall cover, because the settings of the buckles and the slots can only achieve the positioning effect, when the buckle mounting holes on the other side cooperate with each other, the anti-electricity wall cover may fall off. At this time, three to four screws need to be driven into the anti-electricity wall cover and the barrel in the outer shell to fix them, which further makes it inconvenient to install the anti-electricity wall cover.

[0035] Combination Figures 1 to 3 In order to solve the above technical problems, on the one hand, the present application provides a shell structure of an electric water heater, including a barrel 100 in an outer shell and an anti-electricity wall cover 200, a plurality of clips 210 are arranged on the inner wall of the anti-electricity wall cover 200, a plurality of card interfaces 110 are opened on the barrel 100 in the outer shell, and the plurality of clips 210 are used to be simultaneously clipped or disengaged with the plurality of card interfaces 110 to drive the anti-electricity wall cover 200 to be installed or disengaged from the barrel 100 in the outer shell, and the clips 210 include a wedge surface 220, and the wedge surface 220 is used to guide the clips 210 to be clipped into the card interface 110.

[0036] In this embodiment, eight card connectors 210 are provided and eight card interfaces 110 are provided. The card connectors 210 and the card interfaces 110 are provided in a one-to-one correspondence. Six of the eight card connectors 210 are provided on the side of the anti-electrical wall cover 200 where the display screen is located, and the remaining two of the eight card connectors 210 are provided on the side of the anti-electrical wall cover 200 away from the display screen.

[0037] By adopting the above technical solution, when it is necessary to install the barrel 100 in the shell and the anti-electricity wall cover 200, the anti-electricity wall cover 200 is moved toward the barrel 100 in the shell, so that the anti-electricity wall cover 200 drives multiple clamping parts 210 to be clamped into the clamp interface 110 at the same time, thereby realizing the installation of the anti-electricity wall cover 200. The arrangement of multiple clamping parts 210 and multiple clamp interfaces 110 does not require positioning and then installing the anti-electricity wall cover 200, saving the step of positioning the anti-electricity wall cover 200, thereby facilitating the installation and fixing of the anti-electricity wall cover 200; and only the barrel 100 in the shell needs to be fixed. 00, the installation and fixation of the anti-electricity wall cover 200 can be achieved by opening a card interface 110 on the outer shell, and there is no need to simultaneously open card slots and installation ports 113 of different shapes on the inner barrel 100 of the outer shell, and there is no need to set claws and buckles of different shapes on the anti-electricity wall cover 200, thereby facilitating the production of the inner barrel 100 and the anti-electricity wall cover 200 in the outer shell, and reducing the production costs of the inner barrel 100 and the anti-electricity wall cover 200 in the outer shell; the setting of the wedge-shaped surface 220 can guide the card connector 210 to be connected to the card interface 110, thereby further facilitating the installation of the anti-electricity wall cover 200.

[0038] Combination Figure 2 and Figure 3 The card connector 210 includes a connecting rod 211 and a mounting rod 212. The connecting rod 211 is connected to the anti-electricity wall cover 200, and the mounting rod 212 is connected to the connecting rod 211. The card interface 110 is used for allowing the connecting rod 211 and the mounting rod 212 to pass through at the same time. The mounting rod 212 is used to abut against the inner wall of the outer shell barrel 100 to drive the anti-electricity wall cover 200 to be installed on the outer shell barrel 100. In this embodiment, the mounting rod 212 and the connecting rod 211 are integrally arranged.

[0039] By adopting the above technical solution, by moving the anti-electricity wall cover 200 toward the middle barrel 100 of the outer shell, the anti-electricity wall cover 200 drives the connecting rod 211 and the installation rod 212 to pass through the card interface 110, and drives the installation rod 212 to abut against the inner wall of the middle barrel 100 of the outer shell. At this time, the edge of the anti-electricity wall cover 200 abuts against the outer wall of the middle barrel 100 of the outer shell, so that the anti-electricity wall cover 200 is installed on the middle barrel 100 of the outer shell. The setting structure of the connecting rod 211 and the installation rod 212 is simple, which further facilitates the installation and fixation of the anti-electricity wall cover 200 and the middle barrel 100 of the outer shell.

[0040] Combination Figure 2 and Figure 3 The plurality of mounting rods 212 are all along the axial direction of the barrel 100 in the housing (see Figure 2 The mounting rod 212 is arranged perpendicular to the connecting rod 211, and the mounting rod 212 includes an abutting surface 230 for abutting against the inner wall of the barrel 100 in the outer shell, and the abutting surface 230 is located on the surface of the mounting rod 212 facing the anti-electrical wall cover 200, and the abutting surface 230 is used to abut against the inner wall of the barrel 100 in the outer shell to drive the anti-electrical wall cover 200 to be installed on the barrel 100 in the outer shell.

[0041] By adopting the above technical solution, by arranging multiple installation rods 212 along the axial direction of the barrel 100 in the outer shell, the anti-electricity wall cover 200 drives the connecting rods 211 and the installation rods 212 along the axial direction of the barrel 100 in the outer shell to realize the clamping of the multiple installation rods 212, thereby preventing the inconvenience of installing the anti-electricity wall cover 200 due to the obstruction of the wall, and making the anti-electricity wall cover 200 have a larger installation space, thereby further facilitating the installation and fixation of the anti-electricity wall cover 200.

[0042] When the anti-electricity wall cover 200 drives the connecting rod 211 and the mounting rod 212 to pass through the card interface 110, since the abutment surface 230 is located on the surface of the mounting rod 212 facing the anti-electricity wall cover 200, the mounting rod 212 can drive the abutment surface 230 to directly abut against the inner wall of the middle barrel 100 of the outer shell, thereby allowing the anti-electricity wall cover 200 to be installed on the middle barrel 100 of the outer shell, further facilitating the installation of the anti-electricity wall cover 200 and improving the installation and fixing effect between the anti-electricity wall cover 200 and the middle barrel 100 of the outer shell.

[0043] Combination Figure 2 and Figure 3 The clamping member 210 also includes a guide rod 213, which is arranged at the end of the mounting rod 212 away from the connecting rod 211, and a wedge surface 220 is arranged on the guide rod 213, and the wedge surface 220 is used to guide the abutting surface 230 to abut against the inner wall of the barrel 100 in the outer shell; in this embodiment, the widths of the connecting rod 211, the mounting rod 212 and the guide rod 213 are all the same.

[0044] By adopting the above-mentioned technical solution, when the connecting rod 211 drives the installation rod 212 and the guide rod 213 to pass through the card interface 110, the wedge surface 220 can guide the abutment surface 230 to abut against the inner wall of the outer shell barrel 100, thereby realizing the installation and fixation of the anti-electric wall cover 200 and the outer shell barrel 100, and further improving the installation effect of the anti-electric wall cover 200 on the outer shell barrel 100.

[0045] Combination Figure 2 and Figure 3 The wedge-shaped surface 220 is arranged on the surface of the guide rod 213 facing the anti-electrical wall cover 200 , one side of the wedge-shaped surface 220 is connected with the abutting surface 230 , and the other side is inclined and extended in a direction away from the anti-electrical wall cover 200 .

[0046] In this embodiment, one end of the guide rod 213 is integrally arranged on the mounting rod 212, and the other end is inclined and extended in a direction away from the anti-electrical wall cover 200, so that the guide rod 213 drives the wedge surface 220 to be inclined and extended in a direction away from the anti-electrical wall cover 200. By tilting the guide rod 213 as a whole in a direction away from the anti-electrical wall cover 200, there is no need to separately set the wedge surface 220 on the guide rod 213. By bending the guide rod 213 as a whole, the guide rod 213 is inclined, thereby facilitating the production of the guide rod 213 and the wedge surface 220.

[0047] By adopting the above technical solution, when the installation rod 212 and the guide rod 213 pass through the card interface 110 and enter the inner barrel 100 of the outer shell, the wedge surface 220 is inclined and extends in the direction away from the anti-electrical wall cover 200, so that the edge of the card interface 110 is conveniently moved to the bottom of the wedge surface 220. By continuously driving the anti-electrical wall cover 200 to move, the edge of the card interface 110 moves to the position of the abutting surface 230 through the wedge surface 220. At this time, there is a certain distance between the wedge surface 220 and the inner wall of the inner barrel 100 of the outer shell, and the abutting surface 230 can abut against the inner wall of the inner barrel 100 of the outer shell, thereby realizing the installation and fixation between the anti-electrical wall cover 200 and the inner barrel 100 of the outer shell. The wedge surface 220 facilitates guiding the abutting surface 230 to abut against the inner wall of the inner barrel 100 of the outer shell, thereby further facilitating the installation of the anti-electrical wall cover 200.

[0048] Combination Figure 2 and Figure 3 , an arcuate surface 240 is provided at the end of the guide rod 213 away from the mounting rod 212; in the present embodiment, one side of the arcuate surface 240 is connected with the wedge-shaped surface 220, and the other side extends to the surface of the guide rod 213 away from the anti-electrical wall cover 200.

[0049] By adopting the above technical solution, the arc surface 240 can prevent the end of the guide rod 213 away from the installation rod 212 from abutting against the edge of the card interface 110 , thereby facilitating the guide rod 213 to drive the installation rod 212 to pass through the card interface 110 .

[0050] Combination Figure 2 and Figure 3 The connecting rod 211, the mounting rod 212 and the guide rod 213 are all provided with grooves 250 on their surfaces facing away from the anti-electricity wall cover 200, and the plurality of grooves 250 are interconnected.

[0051] In this embodiment, the cross-section of the groove 250 is set in a "U" shape. The end of the "U"-shaped groove 250 close to the anti-electrical wall cover 200 passes through the connecting rod 211, and the end of the "U"-shaped groove 250 away from the anti-electrical wall cover 200 is closed.

[0052] By adopting the above technical solution, the provision of the groove 250 reduces the material consumption of the connecting rod 211 , the mounting rod 212 and the guide rod 213 , thereby reducing the production costs of the connecting rod 211 , the mounting rod 212 and the guide rod 213 .

[0053] Combination Figure 2 and Figure 3 The card interface 110 includes an insertion port 111, a guide port 112 and an installation port 113. The width of the insertion port 111 is greater than the width of the card connector 210, the width of the installation port 113 is equal to the width of the card connector 210, and the guide port 112 is used to guide the card connector 210 from the insertion port 111 to the installation port 113.

[0054] In this embodiment, the insertion port 111, the guide port 112 and the installation port 113 are arranged in sequence along the axial direction of the barrel 100 in the outer shell, the guide port 112 is connected with the insertion port 111 and the installation port 113, and the distance between the two opposite sides of the guide port 112 gradually decreases from the side where the insertion port 111 is located toward the side where the installation port 113 is located. The two opposite sides of the guide port 112 can be tilted at the same time, or one side of the guide port 112 can be horizontal and the other side tilted, so that the guide port 112 can guide the clamping part 210.

[0055] By adopting the above technical solution, by making the width of the insertion port 111 larger than the width of the clip 210, it is convenient to pass the clip 210 through the insertion port 111, and by making the width of the installation port 113 equal to the width of the clip 210, it is convenient to prevent the clip 210 from moving in the installation port 113. The setting of the guide port 112 facilitates the movement of the clip 210 along the insertion port 111 to the installation port 113. The setting of the insertion port 111, the guide port 112 and the installation port 113 facilitates the installation of the clip 210, thereby facilitating the anti-electricity wall cover 200 to be fixed to the barrel 100 in the outer shell.

[0056] Combination Figure 1 , Figure 4 and Figure 5 A water intercepting groove 260 is provided on the outer wall of the anti-electrical wall cover 200 and located above the display screen, and a mounting plate 261 is provided on the inner wall of the anti-electrical wall cover 200 and located at the position of the water intercepting groove 260, and several of the multiple clips 210 are connected between the mounting plate 261 and the anti-electrical wall cover 200.

[0057] In this embodiment, the cross-section of the water intercepting groove 260 is arc-shaped, one side of the mounting plate 261 is fixedly connected to the inner wall of the anti-electrical wall cover 200, and the other side is inclined and extended in a direction away from the anti-electrical wall cover 200, and the connecting rod 211 of the clamping part 210 is fixedly set between the mounting plate 261 and the inner wall of the anti-electrical wall cover 200.

[0058] By adopting the above technical scheme, water on the barrel 100 in the outer shell can flow to the anti-electricity wall cover 200, and flow along the anti-electricity wall cover 200 to the position where the water intercepting groove 260 is located. Due to the setting of the water intercepting groove 260, part of the water can drip along the edge of the water intercepting groove 260, preventing the water from flowing to the position where the display screen is located and causing some impact on the display screen; due to the setting of the water intercepting groove 260, the thickness of the anti-electricity wall cover 200 at the position where the water intercepting groove 260 is located is reduced, and by setting the mounting plate 261 at the position where the water intercepting groove 260 is located, the strength of the anti-electricity wall cover 200 at the position where the water intercepting groove 260 is located is improved; several of the clips 210 are set between the mounting plate 261 and the anti-electricity wall cover 200, the strength of the clips 210 fixed to the anti-electricity wall cover 200 is improved, thereby indirectly improving the installation effect between the anti-electricity wall cover 200 and the barrel 100 in the outer shell.

[0059] On the other hand, the present application provides an electric water heater, comprising a shell, wherein the shell adopts the shell structure of the electric water heater of any of the above embodiments.

[0060] Among them, the shell structure of the electric water heater has been described in detail in the above embodiments, and will not be repeated here.

[0061] When it is necessary to install the anti-electricity wall cover 200 on the barrel 100 in the outer shell, the anti-electricity wall cover 200 drives the connecting rod 211, the installation rod 212 and the guide rod 213 to pass through the insertion port 111, and the anti-electricity wall cover 200 is moved along the axial direction of the barrel 100 in the outer shell, so that the connecting rod 211 moves along the guide port 112 to the installation port 113. Since the guide rod 213 is tilted as a whole in the direction away from the anti-electricity wall cover 200, the arc surface 240 first abuts against the edge of the installation port 113, and then the arc surface 240 guides the wedge surface 220 to abut against the edge of the installation port 113, and finally the wedge surface 220 guides the abutting surface 230 to abut against the edge of the installation port 113, so that the abutting surface 230 abuts against the inner wall of the barrel 100 in the outer shell. At this time, the surrounding of the anti-electricity wall cover 200 is tightly abutted against the outer wall of the barrel 100 in the outer shell. A screw is driven into the middle barrel 100 of the outer shell to prevent the anti-electricity wall cover 200 from retreating from the middle barrel 100 of the outer shell; by passing the connecting rod 211, the installation rod 212 and the guide rod 213 through the card interface 110, the anti-electricity wall cover 200 is continuously moved along the axial direction of the middle barrel 100 of the outer shell to achieve the installation and fixation of the anti-electricity wall cover 200. The fixing method is convenient and simple, and after the clamping piece 210 is clamped with the card interface 110, only one screw needs to be driven in to prevent the anti-electricity wall cover 200 from retreating, which further facilitates the fixing of the anti-electricity wall cover 200 to the middle barrel 100 of the outer shell. When the middle barrel 100 of the outer shell is injection molded, there is no need to set a groove on the middle barrel 100 of the outer shell for the anti-electricity wall cover 200 to be inserted. Only the card interface 110 needs to be opened on the middle barrel 100 of the outer shell to achieve the installation of the anti-electricity wall cover 200, which is convenient for the production of the middle barrel 100 of the outer shell.

[0062] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments, and the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
