[0014] In some embodiments, one of the rear shell and the front shell is provided with two foolproof grooves, and the other of the rear shell and the front shell is provided with a foolproof part;

[0015] When the first fastener is fastened to one of the second fasteners, the foolproof part is embedded in one of the foolproof grooves; when the first fastener is fastened to another second fastener, the foolproof part is embedded in the other foolproof groove.

[0016] In some embodiments, the first fastener includes:

[0017] An elastic arm is connected to the side of the front housing facing the rear housing and is opposite to the disassembly port; and

[0018] A hook is attached to the end of the elastic arm away from the front housing, and the hook is used to engage with the second fastener.

[0019] The elastic arm can undergo elastic deformation under the action of external force, so that the hook part can be separated from the second fastener.

[0020] In some embodiments, the hook has a first guide slope and the second fastener has a second guide slope, and the first guide slope and the second guide slope slide in contact during the hook and the second fastener fastening process.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0054] Home appliances refer to electrical equipment used in homes or similar places, widely applied in all aspects of daily life to improve convenience, comfort, and efficiency. Common home appliances include, but are not limited to: kitchen appliances (such as refrigerators, microwave ovens, and ovens), cleaning appliances (such as washing machines and vacuum cleaners), comfort appliances (such as air conditioners and water heaters), and other multi-functional appliances (such as air purifiers and smart speakers). These devices are powered by electricity to perform various functions and meet users' needs in different scenarios.

[0055] The following description uses an electric water heater as an example to illustrate this embodiment. Other home appliances such as air purifiers, vacuum cleaners, and smart speakers can be considered similarly.

[0056] Electric water heaters, as an indispensable household appliance in modern life, provide people with a convenient hot water bathing experience. With continuous technological development and increasingly diversified user needs, electric water heater products are constantly being innovated to meet the usage requirements of different scenarios. Among these innovations, the diversification of installation methods has become an important development trend for electric water heater products.

[0057] Please see Figure 1 and Figure 2This application provides a household appliance 100, which includes a main body 2. The main body 2 has at least two installation states, namely, at least a vertical installation state (e.g., vertical installation state). Figure 1 ) and horizontal installation status (such as Figure 1 Vertical installation is the traditional installation method, suitable for larger bathrooms or kitchens, making full use of vertical space. Horizontal installation, on the other hand, is suitable for smaller environments, such as narrow bathrooms or corners, making better use of horizontal space.

[0058] like Figure 1 , Figure 2 and Figure 3 As shown, specifically, the main body 2 has a length direction, which is also the main extension direction of the main body 2 structure. The main body 2 includes a shell 210, an upper cover 220, and a lower cover 230. The upper cover 220 and the lower cover 230 are respectively connected to both sides of the shell 210 along the length direction of the main body 2. It can be understood that in the vertical installation state of the home appliance 100, the length direction of the main body 2 is perpendicular to the ground, and the upper cover 220 and the lower cover 230 are arranged opposite each other in the vertical direction, presenting an overall "standing" posture. In the horizontal installation state of the home appliance 100, the length direction of the main body 2 is parallel to the ground, and the upper cover 220 and the lower cover 230 are arranged along the length direction of the main body 2, opposite each other in the horizontal direction, presenting an overall "lying" posture.

[0059] It is important to note that even if the length of the main body 2 is not perfectly perpendicular to the ground, but has a certain angle of inclination (e.g., not exceeding 15 degrees), it is still considered a vertical installation. This design allows the equipment to maintain stability and functionality during actual installation, even if the ground is not perfectly level or there are slight deviations in the installation position. Similarly, even if the length of the main body 2 is not perfectly parallel to the ground, but has a certain angle of inclination (e.g., not exceeding 15 degrees), it is still considered a horizontal installation. This design takes into account potential ground tilt or installation space limitations in actual installation scenarios, ensuring that the equipment remains stable and functions normally when installed horizontally.

[0060] The outer casing 210 can be cylindrical or square. The main function of the outer casing 210, upper end cover 220, and lower end cover 230 is to protect the internal components from the influence of the external environment. They are typically made of metal or high-strength plastic materials. The upper end cover 220 and lower end cover 230 are detachably connected to the outer casing 210 by screws, welding, or other mechanical connections. This design allows the internal components to be installed first during manufacturing, and then the upper end cover 220 and lower end cover 230 to be fixed. Through their tight fit with the outer casing 210, they form a sealed protective space, ensuring the stability and reliability of the internal components under various operating conditions.

[0061] Please continue reading. Figure 3 Furthermore, the outer shell 210, upper end cover 220, and lower end cover 230 enclose a receiving cavity 2A. The main body 2 also includes an inner tank 240, which is housed within the receiving cavity 2A for storing hot water. It is typically made of a metallic material (such as stainless steel or enamel-coated steel plate) and possesses good sealing and pressure resistance. The inner tank 240 is equipped with a cold water inlet pipe and a hot water outlet pipe. A heating element 250 (such as an electric heating tube or heating rod) is also installed inside the inner tank 240, which heats the water to a set temperature through the thermal effect of the electric current. The inner tank 240 typically has good heat preservation properties, reducing heat loss during storage and maintaining the water temperature for a longer period.

[0062] The main body 2 also includes a thermostat (not shown), which is a safety device of the appliance 100 used to prevent the water temperature in the inner tank 240 from becoming too high. The thermostat is typically installed near the inner tank 240 or in the circuit of the heating element 250. When the water temperature exceeds a preset safe temperature, the thermostat automatically cuts off the power to the heating element 250 to prevent equipment damage or danger. The thermostat's design ensures the safety and reliability of the appliance 100 during use.

[0063] In some embodiments, the appliance 100 further includes a bracket 3, which includes a mounting element (not shown) and two mounting supports (not shown). The mounting element is connected to the main body 2, and the two mounting supports are respectively connected to the left and right ends of the mounting element. Each mounting support has at least one hanging hole and a hanging groove located below the hanging hole. The hanging hole is used to connect to an external hanging point (such as a wall hook or bracket) to suspend the appliance. The size of the hanging groove in the left-right direction is larger than the size of the hanging hole. This provides additional support and stability when the appliance 100 is installed horizontally. Through the combined design of the hanging hole and the hanging groove, the bracket 3 can adapt to both vertical and horizontal installation methods. In vertical installation, the hanging hole is used to connect to an external hanging point to ensure stable suspension of the appliance; in horizontal installation, the hanging groove provides additional support to ensure the stability of the appliance in the horizontal direction. The size of the hanging groove is larger than the hanging hole, which can adapt to the needs of different installation environments. Users do not need to reinstall the bracket 3 structure or purchase additional mounting elements, reducing installation costs.

[0064] Please continue reading. Figure 2 and Figure 3The home appliance 100 also includes a display structure 1, which is mounted on the main body 2. The display structure 1 is partially exposed on the outer surface of the housing 210 and is located on the side of the housing 210 facing the user. The display structure 1 can be used to display the working status and related information of the home appliance 100. Exemplarily, a portion of the display structure 1 is embedded in the main body 2, and the display content is externally displayed by providing a through hole 2B on the main body 2. The embedded design makes the outer surface of the electric water heater smoother and cleaner. In other embodiments, the display structure 1 can also be connected to the main body 2 by screwing, snap-fitting, or other methods.

[0065] The home appliance 100 also includes a power board (not shown) and a control board (not shown). The display structure 1 can be connected to the power board via a power cord. The power board can be located inside the main body 2 or integrated into the display structure 1 to reduce the use of external connection cables. The display structure 1 also needs to receive signals from the control board to display the operating status and related information of the electric water heater. Signal connection can be achieved by connecting the display structure 1 to the control board via a signal cable, or by using wireless communication technology (such as Bluetooth, Wi-Fi, etc.) to realize signal transmission between the display structure 1 and the control board.

[0066] Since the home appliance 100 has at least two installation states, in related technologies, the display structure 1 is usually fixedly installed on the main body 2. For example, when an electric water heater is switched between vertical and horizontal installation methods, the text and patterns on the display structure 1 may appear upside down or skewed, causing users to need to adjust their viewing angle or posture when operating, which is inconvenient for users.

[0067] To solve the above problems, such as Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the display structure 1 includes a rear shell 30, a front shell 20, and a display element 10. The rear shell 30 is fixedly mounted on the main body 2. The rear shell 30 and the front shell 20 together define a mounting cavity 1A. The display element 10 is disposed within the mounting cavity 1A. The rear shell 30 may be provided with a connecting hole 30D that connects the receiving cavity and the mounting cavity 1A, so that the display element 10 can be connected to a power board or control board within the main body 2. The display element 10 is used to display the operating status of the home appliance 100, such as displaying information like water temperature, time, and heat level. The display element 10 may be composed of a liquid crystal display (LCD) or a light-emitting diode (LED) display.

[0068] The display 10 is connected to the front housing 20, and the front housing 20 has a light-transmitting opening 21A (e.g., ...). Figure 8 As shown, the light-emitting side of the display element 10 is positioned towards the light-transmitting port 21A. The design of the light-transmitting port 21A can improve the display effect of the display structure 1. The front shell 20 is an external protective component of the display structure 1, which can reduce the risk of damage to the display element 10 due to external forces and improve its service life.

[0069] like Figure 6 and Figure 7 As shown, the display structure 1 also includes a disassembly assembly 40, which includes a first latching member 41 and at least two second latching members 42. The first latching member 41 is disposed on one of the front shell 20 and the rear shell 30, and the at least two second latching members 42 are disposed at intervals on the other of the front shell 20 and the rear shell 30. The first latching member 41 and the second latching member 42 are latched together. One of the first latching member 41 and the second latching member 42 can be an elastic hook, and the other can be a door-shaped slot, which is adapted to the elastic hook. The door-shaped slot can be "L"-shaped or "U"-shaped to accommodate the free end of the first latching member 41. It should be noted that the specific structural forms of the first latching member 41 and the second latching member 42 are not limited to the elastic hook and the gate-shaped slot described above. For example, in other embodiments, the first latching member 41 can be a first magnetic latch, and the second latching member 42 can be a second magnetic latching member, whose magnetism is compatible with the first magnetic latch to ensure a stable connection under normal working conditions and to release the connection when subjected to external force. In addition, a latching structure with a spring, a slotting structure with a sliding lock, etc., can also be used. Therefore, any structural design that can achieve a stable connection and release the connection when subjected to external force is within the protection scope of this invention.

[0070] Since the display component 10 is connected to the front housing 20, when installing the display structure 1, it is only necessary to install the front housing 20 onto the rear housing 30 to complete the installation of the display component 10. During installation, the front housing 20 and the rear housing 30 are aligned so that the first latching member 41 is aligned with one of the second latching members 42. The first latching member 41 and the second latching member 42 are engaged by pressing, thereby fixing the display component 10 and completing the installation.

[0071] If the home appliance 100 is adjusted in its installation position, the display structure 1 on it also needs to be adjusted accordingly to ensure that the display component 10 has the same display angle in different installation positions. If the display angle of the display component 10 changes in different installation positions, the displayed content may be tilted or inverted, thus affecting the user's reading experience. Therefore, maintaining the same display angle ensures that the displayed content is always in a direction that is easy to read, and the user can easily obtain information without adjusting their viewing angle or posture.

[0072] Please continue reading. Figure 6 and Figure 7In this embodiment, the front shell 20 or the rear shell 30, which is provided with the first latching member 41, has a disassembly port 20A opposite to the first latching member 41. The user can use tools such as screwdrivers or small wrenches through the disassembly port 20A to drive the first latching member 41 and the second latching member 42 to release their latching state, that is, the first latching member 41 and the second latching member 42 separate, so that the front shell 20 together with the display member 10 is separated from the rear shell 30. The user can rotate the front shell 20 together with the display member 10 to adjust to the required angle, and then align the first latching member 41 with another second latching member 42 so that the first latching member 41 can be latched and connected with different second latching members 42 to adjust the display angle of the display member 10, and so that the front shell 20 and the display member 10 are reconnected to the rear shell 30.

[0073] Furthermore, the circumferential contours of the front shell 20 and the rear shell 30 are both circular, so that the overall appearance of the display structure 1 remains consistent after the display component 10 is adjusted in angle, avoiding abrupt appearance or visual discontinuity caused by irregular shape.

[0074] This embodiment provides a flexible and reliable display structure 1. Through the design of the detachable component 40, users can freely adjust the display angle according to the installation status of the electric water heater (vertical or horizontal) and their personal usage habits. The cooperative design of the first latch 41 and the second latch 42 not only ensures the stable fixation of the display component 10 but also provides multiple angle options, ensuring that the displayed content is always in a readable orientation. This design significantly improves the user experience while simplifying the installation and maintenance process.

[0075] Understandably, in this embodiment, at least two second latching members 42 are arranged at intervals along the circumference of the front shell 20 or the rear shell 30 to provide different display angles (e.g., 0°, 45°, 90°, 180°, etc.). Since the first latching member 41 is necessarily connected to a second latching member 42, the disassembly port 20A only needs to be set along with the first latching member 41. That is, if the first latching member 41 is set on the front shell 20, then the disassembly port 20A is set on the front shell 20; if the first latching member 41 is set on the rear shell 30, then the disassembly port 20A is set on the rear shell 30. The disassembly port 20A being set opposite to the first latching member 41 allows the user to directly contact the connection position of the first latching member 41 and the second latching member 42 through the disassembly port 20A. That is, the user can accurately find and release the connection between the first latching member 41 and the second latching member 42 during operation, thereby reducing the possibility of misoperation.

[0076] In other embodiments, at least two disassembly ports 20A may be provided, with the two disassembly ports 20A positioned opposite the two second fasteners 42. Referring to the above configuration, the user can also release the engagement relationship between the second fastener 42 and the first fastener 41 through the disassembly ports 20A.

[0077] Please continue reading. Figure 6 and Figure 7 In this embodiment, the first latching member 41 is disposed on the front shell 20, which has a disassembly port 20A formed on the side of the front shell 20 for easy user operation. Correspondingly, at least two second latching members 42 are disposed on the rear shell 30 along the circumference of the rear shell 30. The user can select different second latching members 42 for latching connection as needed, thereby realizing multiple angle adjustments of the display member 10 located on the front shell 20. This design allows the display structure 1 to adapt to different installation states (such as the vertical or horizontal installation of the home appliance 100). The positions of the two second latching members 42 can be configured to correspond to the rotation angle required by the display member 10 in the vertical and horizontal installation states. When the display structure 1 is switched from vertical installation to horizontal installation, the user only needs to switch the first latching member 41 from one of the second latching members 42 to the latching member in the other direction to quickly complete the adjustment of the display angle.

[0078] Furthermore, the line connecting the two second latches 42 to the center of the front housing 20 is perpendicular. Understandably, the angle between the line connecting these two second latches 42 and the center of the light-transmitting opening 21A is 90°. This design allows users to easily achieve a 90° angle adjustment. This corresponds to the required rotation angle of the display component 10 in both horizontal and vertical installation states of the appliance 100. For example, when switching the appliance 100 from vertical to horizontal installation, the user only needs to switch the first latch 41 from one second latch 42 to another vertical latch to quickly adjust the display angle.

[0079] like Figure 7 As shown, in some embodiments, the first latching member 41 includes an elastic arm 411 and a hook 412. The elastic arm 411 is connected to the side of the front shell 20 facing the rear shell 30 and is opposite to the disassembly port 20A. The hook 412 is connected to the end of the elastic arm 411 away from the front shell 20. The hook 412 is used to latch with the second latching member 42, thereby fixing the front shell 20 and the rear shell 30. This latching connection method is simple and reliable and can effectively prevent the front shell 20 and the display member 10 from loosening or falling off during use.

[0080] The elastic arm 411 can undergo elastic deformation under external force, allowing the hook 412 to separate from the second fastener 42, and returns to its original shape after the force is released. This characteristic allows the hook 412 to flexibly engage or disengage from the second fastener 42. The user contacts the elastic arm 411 through the disassembly port 20A and applies external force to it, causing the elastic arm 411 to deform, thereby separating the hook 412 from the second fastener 42.

[0081] Understandably, in other embodiments, the hook 412 may be positioned relative to the disassembly port 20A. The user can push the hook 412 through the disassembly port 20A to cause the elastic arm 411 to undergo elastic deformation, thereby separating it from the second fastener 42. This can achieve the same effect, and will not be elaborated further here.

[0082] Please see Figure 7 , Figure 8 and Figure 9 Specifically, the rear shell 30 has a first opening 30C on the side facing the front shell 20. A second latching member 42 is disposed circumferentially on the first opening 30C. The second latching member 42 includes a latching part 421, which can be engaged with a hook part 412. This latching connection method is simple and reliable, and can effectively prevent the display structure 1 from loosening or falling off. The hook part 412 of the first latching member 41 is disposed on the side of the elastic arm 411 away from the center of the light-transmitting hole, that is, the hook part 412 is engaged with the latching part 421 in the direction of the disassembly port 20A, so that the user can directly operate the elastic arm 411 through the disassembly port 20A. The direction of force can correctly make the hook part 412 move towards the center of the light-transmitting hole, so as to disengage the hook part 412 and the latching part 421.

[0083] Please continue reading. Figure 7 , Figure 8 and Figure 9 In some embodiments, the hook 412 further includes a first guide slope 412A located on its side, and the second latching member 42 includes a second guide slope 421A. During the latching process of the hook 412 and the second latching member 42, the first guide slope 412A and the second guide slope 421A slide in contact, meaning that the inclination angle and shape of the second guide slope 421A match that of the first guide slope 412A. The first guide slope 412A acts as a guide during installation, allowing the hook 412 to more easily approach the second latching member 42. When the user aligns the front shell 20 with the rear shell 30, the first guide slope 412A can automatically guide the hook 412 into the latching part 421 of the second latching member 42, enabling the user to quickly and accurately complete the latching connection during installation. This reduces the time and difficulty required for the user to install the front shell 20 and the rear shell 30.

[0084] like Figure 8 and Figure 9 As shown, to achieve a stable connection between the front shell 20 and the rear shell 30 in the circumferential direction, multiple first fasteners 41 and second fasteners 42 are provided, and they are connected one-to-one. By providing multiple first fasteners 41 and second fasteners 42 and connecting them one-to-one, the front shell 20 and the rear shell 30 are fixed at multiple points in the circumferential direction. This multi-point fixing method significantly enhances the overall stability of the display structure 1, ensuring that it will not loosen or fall off due to external forces during use.

[0085] It should be noted that although there are multiple sets of first latches 41 and second latches 42, only one disassembly port 20A is required. Through this single disassembly port 20A, the user can disconnect a corresponding set of first latches 41 and second latches 42. Once this set of first latches 41 and second latches 42 is disconnected, the connection between the front shell 20 and the rear shell 30 will loosen, allowing the front shell 20 some room to move. The user can use this room to pry open this side and further disconnect other sets of latches. This design facilitates subsequent operations, eliminating the need for the user to individually disconnect each set of first latches 41 and second latches 42, greatly simplifying the assembly and disassembly process and improving efficiency.

[0086] like Figure 8 As shown, to facilitate user identification of the disassembly port 20A, a label is provided on the side of the front cover 20 facing the user. This label can take various forms, such as an arrow, text description, or other graphic symbols. It indicates the specific location of the disassembly port 20A, allowing users to quickly and accurately locate it, thus improving the convenience and efficiency of the disassembly process.

[0087] like Figure 8 and Figure 10 As shown, to improve the correct angle at which the front cover 20 is installed on the rear cover 30 under different installation states, in this embodiment, a guide groove 30B is provided on the side of the rear cover 30 facing the front cover 20. A second fastener 42 is provided in the guide groove 30B, and the guide groove 30B is positioned opposite to the disassembly port 20A. In one specific configuration, the guide groove 30B is located on the side of the rear cover 30 near the lower end cover 230.

[0088] When the appliance 100 is installed vertically, the guide groove 30B is located on the lower side in the vertical direction. After removing the front cover 20, the user can align the marked side with the guide groove 30B, and then fasten the front cover 20 and the rear cover 30 together. At this time, the display 10 will be in the correct display state.

[0089] Accordingly, when the appliance 100 is in a horizontal installation position, the guide groove 30B is located on the side of the main body 2 closer to the lower end cover 230 along its length. After removing the front cover 20, the user aligns the marked side with the guide groove 30B and then fastens the front cover 20 and the rear cover 30 together. At this time, the display 10 will be at the same display angle as in the vertical installation position.

[0090] Through the above design, this embodiment not only improves the installation accuracy of the front shell 20 in different installation states, but also provides users with intuitive installation direction prompts through the optimized position of the guide groove 30B, significantly enhancing the user experience. At the same time, this design ensures that the display component 10 maintains the correct display angle in both vertical and horizontal installation states, further enhancing the product's versatility and applicability.

[0091] like Figure 10 and Figure 11 As shown, furthermore, since multiple sets of first latching members 41 and second latching members 42 are provided, there are more options when adjusting the angle. In order to further optimize the installation and angle adjustment process of the display member 10, and at the same time avoid users from making mistakes at unsuitable installation angles, in some embodiments, one of the rear shell 30 and the front shell 20 is provided with two anti-fooling grooves 30A, and the other of the rear shell 30 and the front shell 20 is provided with an anti-fooling part 23. Understandably, the rear shell 30 is provided with two anti-fooling grooves 30A, which are distributed circumferentially and correspond to the correct positions of the display structure 1 in the vertical installation state and the horizontal installation state of the home appliance 100, respectively. The shape and size of the anti-fooling part 23 match the anti-fooling grooves 30A.

[0092] When the first latching member 41 is latched to one of the second latching members 42, the foolproof part 23 is embedded in one of the foolproof grooves 30A; when the first latching member 41 is latched to another second latching member 42, the foolproof part 23 is embedded in the other foolproof groove 30A, thus ensuring the correct position of the display structure 1 in the vertical installation state and the correct position in the horizontal installation state.

[0093] Please continue reading. Figure 10 and Figure 11 In one configuration, two anti-misalignment parts 23 are positioned on the side of the front shell 20 facing the rear shell 30. If the front shell 20 has not been rotated into position, the anti-misalignment parts 23 cannot be inserted into the anti-misalignment grooves 30A. Due to the restriction of the anti-misalignment parts 23, such as the contact between the anti-misalignment parts 23 and the wall of the outer shell 210, the first latching member 41 and the second latching member 42 cannot be engaged. This design ensures that installation or angle adjustment can only be completed when the correct position is achieved. When attempting to engage, the user will experience significant resistance or be unable to complete the engagement, prompting the user to adjust the position of the front shell 20 until the anti-misalignment parts 23 can be smoothly inserted into the anti-misalignment grooves 30A.

[0094] When installing or adjusting the display angle, users only need to ensure that the error-proof part 23 can be smoothly inserted into the error-proof slot 30A to confirm that the operation is correct. If the error-proof part 23 cannot be inserted into the error-proof slot 30A, the user needs to adjust it to the correct position. This not only prevents users from installing or adjusting at the wrong angle, but also significantly simplifies the operation steps and improves the user experience.

[0095] Correspondingly, in other embodiments, two anti-mistake parts 23 and one anti-mistake groove 30A may also be provided. When the front shell 20 is rotated to the correct position, at least a portion of the anti-mistake part 23 can be embedded in the anti-mistake groove 30A. Its effect can be deduced from the above-mentioned configuration, and will not be elaborated further here.

[0096] like Figure 8 , Figure 11 and Figure 12 As shown, to achieve a stable connection between the display element 10 and the front housing 20, in some embodiments, one of the display element 10 and the front housing 20 is provided with a limiting protrusion 13, and the other of the display element 10 and the front housing 20 is provided with a limiting groove 21B. The limiting protrusion 13 is inserted into the limiting groove 21B. Through the limiting structure, the precise position of the display element 10 within the front housing 20 can be ensured, ensuring that the displayed content is accurately aligned with the light-transmitting hole, avoiding display deviations, and improving the visual effect. Furthermore, the cooperation between the limiting protrusion 13 and the limiting groove 21B can effectively limit the relative displacement between the display element 10 and the front housing 20, especially the displacement in the axial direction of the light-transmitting hole.

[0097] Please continue reading. Figure 8 , Figure 11 and Figure 12In one configuration, a limiting groove 21B is provided on the front shell 20, and limiting protrusions 13 are provided on the display element 10. Multiple limiting protrusions 13 are provided, and these protrusions 13 are unevenly arranged circumferentially around the light-transmitting hole. Specifically, the display element 10 includes a support portion 11 and a display portion 12. The display portion 12 is connected to the side of the support portion 11 facing the light-transmitting hole and is used to display electronic information such as temperature and mode. The support portion 11 extends in a cross shape, which not only provides stable support for the display portion 12 but also allows for diverse layout options for the limiting protrusions 13. The support portion 11 has four branch portions 111, and multiple limiting protrusions 13 are connected to different branch portions 111 of the support portion 11, with adjacent branch portions 111 having different numbers of limiting protrusions 13. For example, one side may have three limiting protrusions 13, while an adjacent side may have one limiting protrusion 13. Correspondingly, the number of limiting slots 21B on the front housing 20 corresponds one-to-one with the limiting protrusions 13. This uneven arrangement ensures that the display component 10 can only be installed on the front housing 20 in one correct manner. If the user attempts to install the display component 10 at the wrong angle or direction, the limiting protrusions 13 and the limiting slots 21B will not match, thus preventing misinstallation.

[0098] like Figure 12 As shown, further, in some embodiments, the front shell 20 has a protruding corner plate 25 facing the display 10, wherein a set of adjacent forked portions 111 are provided with a chamfered angle 111B, which can be used to avoid the corner plate 25, while the adjacent forked portions 111 on the side opposite to the one with the chamfered angle 111B are not provided with a chamfered angle 111B. Due to the presence of the chamfered angle 111B, the user can intuitively identify the correct installation direction when installing the display 10, reducing installation failures or damage caused by incorrect orientation.

[0099] Understandably, when the user incorrectly installs the display component 10 and the front cover 20, the forked portion 111 without the beveled angle 111B will interfere with the corner plate 25. During the installation process, the user can intuitively feel whether the installation is correct, reducing problems caused by incorrect installation.

[0100] like Figure 12 As shown, in some embodiments, the limiting groove 21B is disposed on the front shell 20, and the display structure 1 also includes a hook 24. The hook 24 is connected to the front shell 20 and arranged at intervals with the limiting groove 21B. The hook 24 engages with the surface of the display element 10 opposite to the front shell 20. The design of the hook 24 restricts the position of the display element 10 axially from the light-transmitting hole, preventing the display element 10 from shifting or loosening axially during use. This design ensures the stability of the display element 10 after installation and reduces display problems caused by vibration or external impact.

[0101] Specifically, the hook 24 is connected to the side of the support portion 11 that does not have the beveled angle 111B, and there are two hooks 24. The two hooks 24 are respectively engaged with the surface of a forked portion 111 that is away from the front shell 20, which enhances the connection stability between the display component 10 and the front shell 20.

[0102] In some embodiments, positioning holes 1111A are provided on the two forked portions 111 in the same extending direction. The front cover is provided with positioning posts 26 that are adapted to the positioning holes 1111A. The positioning posts 26 can pass through the positioning holes 1111A. The matching design of the positioning holes 1111A and the positioning posts 26 ensures that the display 10 and the front cover can only be installed in one correct manner when connected. If the rotation direction of the display 10 is incorrect, the positioning posts 26 will not be able to be inserted into the positioning holes 1111A, thus clearly indicating to the user that the installation direction is incorrect. This effectively prevents the user from misinstalling the display 10 and the front cover due to incorrect rotation direction.

[0103] like Figure 6 and Figure 8 As shown, to reduce water ingress at the connection between the front shell 20 and the rear shell 30, the display structure 1 also includes a waterproof boss 60. The waterproof boss 60 is circumferentially arranged around the rear shell 30, specifically around the first opening 30C. At least two second fasteners 42 are evenly spaced circumferentially on the waterproof boss 60. The waterproof boss 60 protrudes towards the front shell 20, and the front shell 20 is fastened to the waterproof boss 60. The waterproof boss 60 forms a water-blocking structure between the front shell 20 and the rear shell 30, effectively preventing water from entering the interior of the display structure 1 circumferentially from the connection between the front shell 20 and the rear shell 30, thus enhancing the waterproof performance.

[0104] Furthermore, the design of the waterproof boss 60 makes the connection between the front shell 20 and the rear shell 30 tighter, reducing visible gaps and improving the overall aesthetics of the product. In other embodiments, the waterproof boss 60 can be integrally molded with the rear shell 30. This integral molding design makes the connection between the waterproof boss 60 and the rear shell 30 more robust, resulting in higher overall structural strength. This design can better withstand external impacts and vibrations, reducing functional problems caused by structural loosening. It also significantly improves waterproof performance; this seamless connection effectively prevents moisture from seeping into the device from the connection point, protecting internal components from moisture.

[0105] like Figure 8 and Figure 11As shown, in some examples, the front shell 20 further includes a front panel 21 and a surrounding panel 22. The front panel 21 has a light-transmitting opening 21A opposite to the display element 10. The aforementioned limiting groove 21B, corner plate 25, positioning post 26, and hook 24 can all be provided on the side of the front panel 21 facing the rear shell 30. The surrounding panel 22 surrounds the periphery of the front panel 21 and the outer periphery of the waterproof protrusion 60. Along the direction away from the rear shell 30, the surrounding panel 22 is inclined towards the center of the front panel 21. When water splashes onto the surrounding panel 22, due to the inclined design of the surrounding panel 22, the water will flow inward along the surface of the surrounding panel 22 (i.e., towards the center of the front panel 21), rather than flowing outward (i.e., at the connection between the front shell 20 and the rear shell 30). This design effectively reduces the possibility of water flowing to the connection between the front shell 20 and the rear shell 30. By reducing water flow to the connection points, the waterproof performance of the display structure 1 is further enhanced, protecting the internal electronic components and display 10 from moisture.

[0106] Furthermore, the inclined design of the enclosure 22 allows water to drain quickly from its surface, reducing the time water remains on the surface and further optimizing drainage. This reduces water accumulation on the enclosure 22 surface, avoiding the risk of leakage due to water accumulation.

[0107] like Figure 6 , Figure 8 and Figure 9 As shown, in some embodiments, the display structure 1 further includes a patch 50 connected to the front housing 20. The patch 50 is configured to cover the display element 10, preventing dust, moisture, or other impurities from entering the display element 10, thereby protecting the display element 10 from external environmental influences and extending its service life. The patch 50 also provides an additional layer of protection for the display element 10, preventing blurring or damage to the display content caused by external scratches.

[0108] The patch 50 is made of transparent or semi-transparent material to ensure that the displayed content can be clearly seen through the patch 50 without affecting the user's reading experience.
