Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a water tank anti-tipping structure and a garment steamer. Background Technology

[0002] In the field of home appliances, for devices that require water tanks, the stability of the tank's installation and the ease of disassembly directly affect the user experience. Existing water tank structures, some assembled using simple placement or single-positioning methods, are prone to lateral displacement or even tipping over due to collisions or movement, leading to leaks. Others employ fixed connection designs to improve anti-tipping performance, but these make it difficult to quickly disassemble the tank for adding water or cleaning, failing to balance anti-tipping stability and ease of disassembly, thus impacting user experience. Utility Model Content

[0003] Therefore, it is necessary to provide a water tank anti-tipping structure and a garment steamer to address the problem that existing water tank structures cannot simultaneously ensure anti-tipping stability and ease of disassembly and assembly.

[0004] A water tank anti-tipping structure includes: a base, the base having an installation groove, a connecting hole, and a positioning groove; a water tank, the water tank being detachably mounted on the base and partially located within the installation groove, the water tank including a water tank body, a limiting protrusion, and a positioning protrusion, the limiting protrusion and the positioning protrusion both being disposed on the water tank body, the limiting protrusion being adjacent to the connecting hole, and the positioning protrusion being at least partially located within the positioning groove; and a limiting key, the limiting key being disposed on the base and located on the side of the base away from the water tank, a portion of the limiting key being able to pass through the connecting hole and abut against the limiting protrusion, or a portion of the limiting key being able to move away from the limiting protrusion.

[0005] The aforementioned anti-tipping structure for the water tank initially accommodates and limits the water tank through the mounting groove of the base. The cooperation between the positioning protrusion of the water tank and the positioning groove of the base enables the water tank to be accurately positioned on the base, preventing the water tank from shifting laterally relative to the base. The engagement of the limit key with the limit protrusion of the water tank further fixes the water tank longitudinally and laterally, preventing the water tank from tipping over. At the same time, the design of the limit key being located away from the limit protrusion ensures that the water tank is detachable, taking into account both the anti-tipping stability of the water tank and the convenience of disassembly and assembly.

[0006] In one embodiment, the connecting holes are located on the wall of the mounting groove, and there are one or more connecting holes. The number of limiting keys is the same as the number of connecting holes. The number of connecting holes and limiting keys on the base corresponds to the number of limiting keys, and there are one or more of them. All of them can effectively abut and limit the limiting protrusion of the water tank through the cooperation of the limiting keys and connecting holes, meeting the basic anti-tipping requirements. When there are multiple limiting keys, they can also abut and limit the limiting protrusion of the water tank from different positions on the wall of the mounting groove, making the limiting force on the water tank more uniform, avoiding excessive force on a single limiting point that may cause limiting failure, further enhancing the stability of the connection between the water tank and the base, and improving the anti-tipping effect.

[0007] In one embodiment, there are multiple positioning protrusions located on the side of the water tank body near the base. The positioning protrusions extend towards the mounting groove, and the positioning groove is located at the bottom of the mounting groove, extending away from the water tank. There are multiple positioning grooves, each adapted to one of the positioning protrusions. The adaptation of the multiple positioning protrusions of the water tank to the multiple positioning grooves of the base increases the positioning contact points between the water tank and the base, precisely limiting the horizontal displacement of the water tank within the mounting groove of the base, and preventing the water tank from tipping over due to external forces. The design of the positioning protrusions extending towards the mounting groove and the positioning grooves extending away from the water tank ensures a deeper fit and stronger positioning stability.

[0008] In one embodiment, the end of the positioning protrusion near the base is parallel to the horizontal plane, and multiple positioning protrusions are spaced apart circumferentially along the bottom of the water tank body near the base. The parallel horizontal plane of the positioning protrusion near the base ensures surface contact between the positioning protrusion and the bottom of the positioning groove on the base, resulting in more stable force distribution and preventing the water tank from tilting after installation due to tilted contact surfaces. Simultaneously, this parallel end face serves as a support surface when the water tank is placed alone, allowing it to be stably placed on a horizontal surface after being removed from the base, preventing it from tipping over. The multiple positioning protrusions spaced apart circumferentially along the bottom of the water tank body allow for uniform positioning from the bottom perimeter, further limiting circumferential rotation and lateral displacement of the water tank and improving the overall stability of the water tank after installation.

[0009] In one embodiment, the limiting key includes a fixed member, a movable member, and an elastic member. The fixed member is disposed on the base, and the movable member and the elastic member are disposed on the fixed member. The movable member partially passes through the connecting hole and abuts against the limiting protrusion. One end of the elastic member abuts against the movable member, and the other end of the elastic member abuts against the fixed member. The fixing component of the limit key provides a stable mounting base for the moving and elastic components. The elastic component can continuously push the moving component against the limit protrusion of the water tank through its own elastic force, ensuring a tight fit between the two and preventing the moving component from detaching from the limit protrusion due to external forces such as vibration, thus losing the limiting effect. At the same time, the cooperation of the fixing component, moving component, and elastic component of the limit key ensures that the moving component continuously and tightly abuts against the limit protrusion under the action of elastic force. Therefore, when removing the water tank, it is necessary to overcome the elastic force of the elastic component to push the moving component away from the limit protrusion, ensuring that the water tank will not accidentally detach from the base without intentional human intervention. The movable design of the moving component allows for position adjustment through the deformation of the elastic component during the water tank disassembly and assembly process, without the need to disassemble the limit key, simplifying the water tank disassembly and assembly process.

[0010] In one embodiment, the fixing member has a movable groove, the opening of which is opposite to the connecting hole. The inner diameter of the movable groove is larger than the diameter of the connecting hole. The movable member and the elastic member are partially located within the movable groove. One end of the elastic member abuts against the bottom of the movable groove, and the other end of the elastic member is wound around the movable member. The movable groove of the fixing member of the limit key provides a limited space for the movable member and the elastic member, preventing lateral displacement during operation and ensuring that the movable member always moves along the axis of the connecting hole of the base, ensuring precise contact with the limit protrusion of the water tank. The inner diameter of the movable groove is larger than the diameter of the connecting hole, which can prevent the movable member from getting stuck at the edge of the connecting hole during movement. The elastic member is wound around the movable member and abuts against the bottom of the movable groove, so that the direction of the elastic force is always along the axis of the movable member, ensuring the stability of the force exerted by the elastic member on the movable member and improving the reliability of the limit key.

[0011] In one embodiment, the movable member includes a fixed end, an abutment protrusion, and a movable end. The movable end abuts against the limiting protrusion. The abutment protrusion is located between the fixed end and the movable end, and abuts against the side of the base away from the water tank. The elastic member is wound around the fixed end and abuts against the abutment protrusion. The abutment protrusion of the movable member abuts against the side of the base away from the water tank, which can limit the excessive movement of the movable member towards the water tank and prevent the movable member from affecting the normal installation of the water tank due to excessive insertion into the connection hole of the base. The elastic member is wound around the fixed end of the movable member and abuts against the abutment protrusion, so that the elastic force of the elastic member can be accurately transmitted to the movable member through the abutment protrusion, ensuring that the movable end of the movable member stably abuts against the limiting protrusion of the water tank. At the same time, the fixed end can play a positioning role for the elastic member and prevent the elastic member from shifting during deformation.

[0012] In one embodiment, the length of the movable groove is less than the free length of the elastic element. The shorter length of the movable groove in the fixing member compared to the free length of the elastic element ensures that the elastic element remains compressed after installation within the movable groove. This continuously provides the movable element with an elastic force towards the limiting protrusion in the water tank, ensuring that the movable element and the limiting protrusion remain in close contact. This prevents the limiting effect from weakening or failing due to relaxation of the elastic element, thus improving the long-term reliability of the limiting key and the stability of the water tank's anti-tipping structure.

[0013] In one embodiment, the limiting protrusion is inclined relative to the bottom of the mounting groove on both the side near the mounting groove and the side away from the mounting groove. The movable member is also inclined relative to the bottom of the mounting groove on both the side near the mounting groove and the side away from the mounting groove. The inclination angle of the limiting protrusion is adapted to the inclination angle of the movable member. When the water tank is disassembled or installed, the movable member slides relative to the limiting protrusion, the elastic member is compressed, and the movable member moves away from the connecting hole. The inclined surface angle of the limiting protrusion of the water tank is matched with that of the movable part of the limiting key. During water tank installation, the inclined surface of the limiting protrusion can push the movable part to slide along the inclined surface and compress the elastic element. The movable part automatically moves away from the connection hole of the base, and the water tank can be installed without manual operation of the limiting key. During disassembly, the water tank moves upward, and the inclined surface of the limiting protrusion can also push the movable part to slide and compress the elastic element, so that the movable part disengages from the limiting protrusion. This simplifies the water tank disassembly and assembly steps and improves the convenience of use. At the same time, the inclined surface fit can ensure the contact area when the movable part abuts the limiting protrusion, without affecting the limiting effect.

[0014] The second aspect of this application discloses a garment steamer, which includes the aforementioned anti-tipping structure for the water tank.

[0015] The aforementioned garment steamer, through the coordinated operation of its various structures, effectively prevents the water tank from tipping over due to external forces such as collisions or movement during use, avoiding water leakage caused by water tank tipping and ensuring the normal operation of the garment steamer. At the same time, the detachable water tank facilitates users to add water and clean the water tank, and after the water tank is removed, it can be stably placed on a horizontal surface by the positioning protrusion, improving the reliability of the garment steamer and the user experience.

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0035] The water tank anti-tipping structure and garment steamer of this utility model are described below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figures 1 to 13 As shown, this embodiment discloses a water tank anti-tipping structure, including a base 1, which has an installation groove 101, a connecting hole 102, and a positioning groove 103; a water tank 2, which is detachably mounted on the base 1 and partially located in the installation groove 101. The water tank 2 includes a water tank body 21, a limiting protrusion 22, and a positioning protrusion 23. The limiting protrusion 22 and the positioning protrusion 23 are both mounted on the water tank body 21. The limiting protrusion 22 is adjacent to the connecting hole 102, and the positioning protrusion 23 is at least partially located in the positioning groove 103; and a limiting key 3, which is mounted on the base 1 and located on the side of the base 1 away from the water tank 2. A portion of the limiting key 3 can pass through the connecting hole 102 and abut against the limiting protrusion 22, or a portion of the limiting key 3 can move away from the limiting protrusion 22.

[0038] The water tank anti-tipping structure disclosed in this application initially accommodates and limits the water tank 2 through the mounting groove 101 of the base 1. The positioning protrusion 23 of the water tank 2 cooperates with the positioning groove 103 of the base 1 to achieve precise positioning of the water tank 2 on the base 1, preventing the water tank 2 from shifting laterally relative to the base 1. The abutting cooperation between the limit key 3 and the limit protrusion 22 of the water tank 2 can further fix the water tank 2 longitudinally and laterally to prevent the water tank 2 from tipping over. At the same time, the design of the limit key 3 being able to be far away from the limit protrusion 22 ensures that the water tank 2 is detachable, taking into account both the anti-tipping stability of the water tank 2 and the convenience of disassembly and assembly.

[0039] like Figures 1 to 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the connecting hole 102 is located on the groove wall of the mounting groove 101, the number of connecting holes 102 is one or more, and the number of limiting keys 3 is the same as the number of connecting holes 102. The number of connecting holes 102 and limiting keys 3 on the base 1 corresponds to the number of one or more, and all of them can effectively abut and limit the limiting protrusion 22 of the water tank 2 through the cooperation of the limiting keys 3 and the connecting holes 102, thus meeting the basic anti-tipping requirements; when there are multiple, they can also abut and limit the limiting protrusion 22 of the water tank 2 from different groove wall positions of the mounting groove 101, making the limiting force on the water tank 2 more uniform, avoiding excessive force on a single limiting point leading to limiting failure, further enhancing the stability of the connection between the water tank 2 and the base 1, and improving the anti-tipping effect.

[0040] like Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: there are multiple positioning protrusions 23, which are located on the side of the water tank body 21 near the base 1. The positioning protrusions 23 extend toward the mounting groove 101, and the positioning groove 103 is located at the bottom of the mounting groove 101. The positioning groove 103 extends away from the water tank 2, and there are multiple positioning grooves 103 that are adapted to the multiple positioning protrusions 23. The multiple positioning protrusions 23 of the water tank 2 are adapted to the multiple positioning grooves 103 of the base 1, which increases the positioning contact points between the water tank 2 and the base 1. This can accurately limit the horizontal displacement of the water tank 2 within the mounting groove 101 of the base 1, avoiding the risk of the water tank 2 tipping over due to displacement caused by external forces. The design of the positioning protrusions 23 extending toward the mounting groove 101 and the positioning grooves 103 extending away from the water tank 2 makes the mating depth between the two more sufficient and the positioning stability stronger.

[0041] In addition to the features of the above embodiments, this embodiment further specifies that: the end of the positioning protrusion 23 near the base 1 is parallel to the horizontal plane, and multiple positioning protrusions 23 are spaced apart circumferentially along the bottom of the water tank body 21 near the base 1. The parallel horizontal plane of the end of the positioning protrusion 23 near the base 1 of the water tank 2 not only ensures that the positioning protrusion 23 is in surface contact with the bottom of the positioning groove 103 of the base 1, resulting in more stable force distribution and avoiding tilting of the water tank 2 after installation due to the tilting of the contact end face; at the same time, the parallel end face can also serve as a support surface when the water tank 2 is placed alone, so that the water tank 2 can be stably placed on the horizontal plane after being removed from the base 1, and is not easy to tip over; the multiple positioning protrusions 23 are spaced apart circumferentially along the bottom of the water tank body 21 of the water tank 2, which can uniformly position the water tank 2 from the bottom periphery, further restricting the circumferential rotation and lateral displacement of the water tank 2, and improving the overall stability of the water tank 2 after installation.

[0042] like Figure 2 , Figure 4 , Figure 5 , Figure 8 , Figure 11 , Figure 12 and Figure 13 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the limiting key 3 includes a fixing member 31, a movable member 32 and an elastic member 33. The fixing member 31 is disposed on the base 1, the movable member 32 and the elastic member 33 are disposed on the fixing member 31, the movable member 32 partially passes through the connecting hole 102 and abuts against the limiting protrusion 22, one end of the elastic member 33 abuts against the movable member 32, and the other end of the elastic member 33 abuts against the fixing member 31. The fixing part 31 of the limit key 3 provides a stable installation base for the movable part 32 and the elastic part 33. The elastic part 33 can continuously push the movable part 32 against the limiting protrusion 22 of the water tank 2 through its own elastic force, ensuring the tightness of the contact between the two and preventing the movable part 32 from detaching from the limiting protrusion 22 due to external forces such as vibration, thus losing the limiting effect. At the same time, the cooperation of the fixing part 31, the movable part 32 and the elastic part 33 of the limit key 3 ensures that the movable part 32 continuously and tightly abuts against the limiting protrusion 22 under the action of elastic force. Therefore, when removing the water tank 2, it is necessary to overcome the elastic force of the elastic part 33 to push the movable part 32 away from the limiting protrusion 22, ensuring that the water tank 2 will not accidentally detach from the base 1 without human intentional operation. The movable design of the movable part 32 can be adjusted in position through the deformation of the elastic part 33 during the disassembly and assembly of the water tank 2, without the need to disassemble the limit key 3, simplifying the disassembly and assembly process of the water tank 2.

[0043] In addition to the features of the above embodiments, this embodiment further specifies that: the fixing member 31 is provided with a movable groove 3101, the opening of the movable groove 3101 is opposite to the connecting hole 102, the inner diameter of the movable groove 3101 is larger than the hole diameter of the connecting hole 102, the movable member 32 and the elastic member 33 are partially located in the movable groove 3101, one end of the elastic member 33 abuts against the bottom of the movable groove 3101, and the other end of the elastic member 33 is wrapped around the movable member 32. The movable groove 3101 of the fixing part 31 of the limit key 3 provides a limited space for the movable part 32 and the elastic part 33 to avoid lateral displacement of the movable part 32 and the elastic part 33 during operation, ensuring that the movable part 32 always moves along the axis of the connecting hole 102 of the base 1, and ensuring precise contact with the limiting protrusion 22 of the water tank 2. The inner diameter of the movable groove 3101 is larger than the diameter of the connecting hole 102, which can prevent the movable part 32 from getting stuck with the edge of the connecting hole 102 during movement. The elastic part 33 is wrapped around the movable part 32 and abuts against the bottom of the movable groove 3101, so that the direction of the elastic force is always along the axis of the movable part 32, ensuring the stability of the force exerted by the elastic part 33 on the movable part 32, and improving the working reliability of the limit key 3.

[0044] In addition to the features of the above embodiments, this embodiment further specifies that: the movable member 32 includes a fixed end 321, an abutting protrusion 322 and a movable end 323, the movable end 323 can abut against the limiting protrusion 22, the abutting protrusion 322 is located between the fixed end 321 and the movable end 323, the abutting protrusion 322 abuts against the side of the base 1 away from the water tank 2, and the elastic member 33 is wound around the fixed end 321 and abuts against the abutting protrusion 322. The abutting protrusion 322 of the movable part 32 abuts against the side of the base 1 away from the water tank 2, which can limit the excessive movement of the movable part 32 towards the water tank 2 and prevent the movable part 32 from being excessively inserted into the connection hole 102 of the base 1, thus affecting the normal installation of the water tank 2. The elastic part 33 is wrapped around the fixed end 321 of the movable part 32 and abuts against the abutting protrusion 322, so that the elastic force of the elastic part 33 can be accurately transmitted to the movable part 32 through the abutting protrusion 322, ensuring that the movable end 323 of the movable part 32 stably abuts against the limiting protrusion 22 of the water tank 2. At the same time, the fixed end 321 can play a positioning role for the elastic part 33, preventing the elastic part 33 from shifting during deformation.

[0045] In addition to the features of the above embodiments, this embodiment further specifies that the length of the movable groove 3101 is less than the free length of the elastic member 33. The shorter length of the movable groove 3101 of the fixing member 31 compared to the free length of the elastic member 33 ensures that the elastic member 33 remains compressed after being installed in the movable groove 3101. This continuously provides the movable member 32 with an elastic force towards the limiting protrusion 22 of the water tank 2, ensuring that the movable member 32 and the limiting protrusion 22 always maintain a tight contact. This prevents the limiting effect from weakening or failing due to the loosening of the elastic member 33, thereby improving the long-term working reliability of the limiting key 3 and the stability of the anti-tipping structure of the water tank 2.

[0046] like Figure 3 , Figure 5 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the side of the limiting protrusion 22 near the mounting groove 101 and the side away from the mounting groove 101 are both inclined relative to the bottom of the mounting groove 101; the side of the movable member 32 near the mounting groove 101 and the side away from the mounting groove 101 are both inclined relative to the bottom of the mounting groove 101; the inclination angle of the limiting protrusion 22 is adapted to the inclination angle of the movable member 32; when the water tank 2 is disassembled or installed, the movable member 32 slides relative to the limiting protrusion 22, the elastic member 33 is compressed, and the movable member 32 moves away from the connecting hole 102. The inclined surface angle of the limiting protrusion 22 of water tank 2 is adapted to that of the movable part 32 of the limiting key 3. When water tank 2 is installed, the inclined surface of the limiting protrusion 22 can push the movable part 32 to slide along the inclined surface and compress the elastic part 33. The movable part 32 automatically moves away from the connection hole 102 of the base 1. The installation of water tank 2 can be completed without manual operation of the limiting key 3. When disassembling, water tank 2 moves upward. The inclined surface of the limiting protrusion 22 can also push the movable part 32 to slide and compress the elastic part 33, so that the movable part 32 is disengaged from the limiting protrusion 22. This simplifies the disassembly and assembly steps of water tank 2 and improves the convenience of use. At the same time, the inclined surface can ensure the contact area when the movable part 32 and the limiting protrusion 22 abut, without affecting the limiting effect.

[0047] Example 2

[0048] like Figures 1 to 13 As shown in the figure, this embodiment discloses a garment steamer, including a water tank anti-tipping structure.

[0049] The garment steamer disclosed in this application effectively prevents the water tank 2 from tipping over due to external forces such as collisions or movement during use through the cooperation of various structures, avoiding water leakage caused by the tipping of the water tank 2 and ensuring the normal operation of the garment steamer. At the same time, the detachability of the water tank 2 makes it easy for users to add water and clean the water tank 2. After the water tank 2 is removed, it can be stably placed on a horizontal surface by the positioning protrusion 23, which improves the reliability of the garment steamer and the user experience.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
