Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a water tank and an air treatment device. Background Art

[0002] At present, for air treatment devices with a water tank assembly, such as humidifiers, a water level detection structure needs to be provided. Generally, a floating bottle bracket is arranged in the water tank. Under the buoyancy of the water in the water tank, the floating bottle rises and falls in the floating space of the floating bottle bracket to feedback whether the water level in the water tank is too low.

[0003] The floating bottle bracket is usually installed in the water tank by means of snap-fastening or rotational clamping. When it is necessary to clean or replace the floating bottle, the operation of disassembling the floating bottle is inconvenient, which affects the user experience. Summary of the Utility Model

For this reason, an object of the utility model is to provide a water tank and an air treatment device, in which a floating guide part on the floating bottle and a fixed sleeve are limitedly matched or separated between a limiting component and a matching structure, so as to limit the floating bottle or unlock the connection between the floating bottle and the fixed sleeve, and the disassembly is convenient.

[0005] A first aspect of the utility model provides a water tank, comprising:

[0006] A box body assembly defining a water storage cavity; a bracket assembly arranged in the water storage cavity, the bracket assembly comprising a fixed sleeve which defines a floating space and a floating channel communicating with the floating space, the floating channel and the floating space are arranged in sequence along the height direction of the box body assembly, and the floating space communicates with the water storage cavity; a floating bottle comprising a floating main body and a floating guide part, the floating main body is floatingly arranged in the floating space, and the floating guide part penetrates through the floating channel; a limiting component, one of the floating guide part and the fixed sleeve is provided with a movable channel extending along the radial direction of the floating bottle, and the other is provided with a matching structure, and the limiting component is telescopically arranged in the movable channel to be limitedly matched or separated from the matching structure.

[0007] For the water tank of the utility model, by telescoping the limiting component in the movable channel, when the user needs to disassemble the floating bottle, only an axial acting force needs to be applied to the floating guide part, the limiting component contracts along the movable channel and is separated from the matching structure. At this time, the connection between the floating bottle and the fixed sleeve is disengaged, and the operation of disassembling the floating bottle is convenient.

[0008] In some embodiments, the fixed sleeve includes: a sleeve body, the sleeve body defines the floating space, and the top wall of the sleeve body is provided with a movable hole; a mounting seat, which is arranged on the top of the sleeve body, the mounting seat defines the floating channel, and the floating channel is connected with the floating space through the movable hole.

[0009] The fixed sleeve is configured to consist of two parts: a sleeve body and a mounting seat. The floating body of the float bottle is disposed on the sleeve body. The floating guide portion passes through the mounting seat to play a guiding role, limiting the float bottle to be able to rise and fall along the floating channel to detect the water level in the water storage chamber, thereby avoiding tilting of the float bottle and causing false alarm detection results, thereby making the water level detection results accurate.

[0010] According to some embodiments of the utility model, a mounting portion extending radially outward along the float bottle is provided on the inner side of the mounting seat, and the mounting portion defines the movable channel.

[0011] By providing a mounting portion radially outward along the floating bottle, on the one hand, the telescopic direction of the telescopic assembly is limited to facilitate cooperation with the matching structure, and on the other hand, a storage space is provided for the telescopic assembly so that the telescopic assembly can be stored in the mounting portion.

[0012] According to some embodiments of the utility model, the matching structure includes a first limit ring and a second limit ring which are arranged on the floating guide portion at intervals along the axial direction of the float bottle, and at least a portion of the structure of the limit assembly is configured to move between a first position and a second position along the radial direction of the float bottle, wherein, in the first position, the projection of at least a portion of the structure in a first reference plane coincides with the projections of the first limit ring and the second limit ring in the first reference plane respectively, and in the second position, the projection of at least a portion of the structure in the first reference plane is staggered with the projections of the first limit ring and the second limit ring in the first reference plane respectively, and the first reference plane is perpendicular to the axis of the float bottle.

[0013] In the first position, at least part of the structure of the limiting assembly is between the first limiting ring and the second limiting ring. During the lifting and lowering of the floating bottle, at least part of the structure of the limiting assembly is limited by the first limiting ring and the second limiting ring, and the floating bottle will not be disconnected from the fixed sleeve. In the second position, the limiting assembly is stored in the movable channel and is not limited by the first limiting ring and the second limiting ring, so it is easy to disassemble.

[0014] According to some embodiments of the present invention, the diameter of the movable hole is not less than the outer diameter of any one of the first limiting ring and the second limiting ring.

[0015] Set the aperture of the movable hole to be not less than the outer diameter of any one of the first limiting ring and the second limiting ring, so that both the first limiting ring and the second limiting ring can pass through the movable hole for installation, which is beneficial to improving the reliability of the structure.

[0016] According to some embodiments of the present invention, the limiting assembly includes:

[0017] A locking pin, the locking pin is telescopically arranged in the movable channel, and the locking pin is adapted to be between the first position and the second position. In the first position, the end of the locking pin facing the floating bottle is located between the first limiting ring and the second limiting ring. In the second position, the end of the locking pin facing the floating bottle is located outside the first limiting ring and the second limiting ring; an elastic member, the elastic member is arranged in the movable channel, the elastic member is sleeved outside the locking pin, and is respectively connected to the channel wall of the movable channel and the locking pin.

[0018] The structure for the limiting member to move between the first position and the second position may include a locking pin. Through the cooperation of the elastic member and the locking pin, when the floating bottle is installed, the user or worker applies an axial force to the floating bottle, and the limiting structure on the floating bottle squeezes the elastic member and the locking pin to contract in the movable channel. At this time, the locking pin is in the second position. Continuing to push the floating bottle, the locking pin resets to the first position under the action of the elastic member. At this time, the end of the locking pin facing the floating bottle is located between the first limiting ring and the second limiting ring, limiting the position of the floating bottle and completing the installation; when disassembling, the user or worker applies an axially opposite force to the floating bottle, and the limiting structure on the floating bottle squeezes the elastic member and the locking pin to contract in the movable channel. At this time, the locking pin is in the second position. Continuing to press the floating bottle, the locking pin resets to the first position under the action of the elastic member, and the floating bottle is disconnected from the fixed sleeve, and the disassembly and assembly operation of the floating bottle is convenient.

[0019] Further, a connecting ring plate is provided on the outer side wall of the locking pin, one end of the elastic member is connected to the inner wall of the movable channel facing the floating bottle, and the other end is connected to the connecting ring plate.

[0020] By providing the connecting ring plate, a force application surface for the elastic member is provided, which is beneficial to improving the reliability of the structure. The structure is simple, and it is convenient to process the connecting ring plate on the outer wall of the locking pin.

[0021] According to some embodiments of the present invention, a through hole is provided on the inner wall of the movable channel facing the floating bottle, and the end of the locking pin away from the floating bottle passes through the through hole; an installation limiting structure is provided at the end of the locking pin away from the floating bottle, and the installation limiting structure is configured to be in limiting cooperation with the through hole.

[0022] The end of the locking pin away from the avoidance structure slides through the through hole, so that during the installation and disassembly of the floating bottle, the locking pin has a farther stroke along the active channel away from the floating bottle, which facilitates the installation and disassembly of the floating bottle and avoids the end of the locking pin away from the floating bottle from colliding with the active channel, thereby improving the reliability of the structure.

[0023] The installation limit structure includes a limit platform, which includes a first end axially away from the float bottle and a second end close to the float bottle, the outer diameter of the first end is smaller than the through hole, the outer diameter from the first end to the second end gradually increases, the outer diameter of the second end exceeds the through hole, and the side wall of the second end abuts against the side wall of the installation portion away from the float bottle.

[0024] Through the limiting effect of the limiting platform, the locking pin is restricted from moving to the first position and then further moving toward the floating bottle, thereby avoiding interference and collision between the locking pin and the floating bottle, resulting in damage to the floating bottle, which is beneficial to further improve the reliability of the structure.

[0025] Furthermore, the first end of the limiting platform defines a deformation groove.

[0026] The deformation groove is provided to provide a deformation margin for the limit table, so that the locking pin is easy to install when it is assembled into the movable channel.

[0029] According to some embodiments of the utility model, one of the mounting seat and the sleeve body is provided with a latch tongue, and the other is provided with a latch groove, and the mounting seat and the sleeve body are connected by the latch tongue being latched in the latch groove.

[0030] The mounting seat and the sleeve body are connected by a clamping tongue clamped in a clamping groove, and the structure is simple and the installation is convenient.

[0031] According to some embodiments of the utility model, the mounting seat includes: a first side plate, a second side plate and a transition connecting plate, the first side plate and the second side plate are spaced apart along the radial direction of the float bottle, the transition connecting plate is respectively connected to the first side plate and the second side plate at one end away from the sleeve body, the second side plate defines the floating channel and the movable channel, the tongue is provided on the first side plate, and the end of the second side plate away from the transition connecting plate abuts against the bottom wall of the sleeve body.

[0032] The mounting base is configured as a structure composed of a first side plate, a second side plate, and a transition connecting plate. On the one hand, it is convenient for design and processing. On the other hand, a cavity is formed between the first side plate and the second side plate, which is beneficial to saving raw materials and thus reducing costs.

[0033] In some embodiments, the bracket assembly further includes a filter element mounting frame disposed outside the fixed sleeve, and the filter element mounting frame is fixedly connected to the fixed sleeve through a connecting rod; the water tank further includes: a filter element, and the filter element is sleeved on the filter element mounting frame.

[0034] By providing a filter element mounting frame with a filter element outside the fixed sleeve, on the one hand, impurities contained in the water in the water tank are filtered by the filter element, thereby improving the user experience. On the other hand, the total mass of the bracket assembly is increased, enabling the fixed sleeve to sink to the bottom of the water storage cavity to ensure accurate water level detection for the floating bottle.

[0035] The second aspect of the present utility model further provides an air treatment device, including: a water tank as described above.

[0036] For the air treatment device of the present utility model, when it is necessary to disassemble the floating bottle for cleaning or replacement, only an axial force towards the floating body needs to be applied to the floating guiding part, and the limiting component contracts along the moving channel and separates from the matching structure. At this time, the floating bottle is disconnected from the fixed sleeve, and the operation of disassembling the floating bottle is convenient.

[0056] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0057] For an air treatment device with a water tank assembly, such as a humidifier, etc., the water level in the water tank is detected by a floating bottle. When replacing or cleaning the existing floating bottle, the disassembly operation is inconvenient.

[0058] In view of this, the present application provides a water tank and an air treatment device. The floating guiding part on the floating bottle and the fixed sleeve are limitedly fitted or separated through the limiting component and the matching structure, so as to limit the floating bottle or unlock the connection between the floating bottle and the fixed sleeve, and the disassembly is convenient.

[0059] The following refers to Figures 1 to 7 Describe a water tank 1 according to the first aspect of the present invention.

[0060] Refer to Figures 1 to 7 , the water tank 1 of this embodiment can be used for an air treatment device, such as a humidifier, or can also be used for other types of water-using devices. The water tank 1 may include: a box body assembly 10, a bracket assembly 20, a floating bottle 30, and a limiting assembly 40.

[0061] The box body assembly 10 may include a box main body, and the box main body defines a water storage cavity 11. The water storage cavity 11 can be used as a water storage and water supply structure for the air treatment device 2 to supply water to other components (such as an atomization assembly) of the air treatment device 2.

[0062] The bracket assembly 20 is arranged in the water storage cavity 11. The bracket assembly 20 may include a fixed sleeve 21. The fixed sleeve 21 can be used to accommodate the floating bottle 30. The fixed sleeve 21 defines a floating space 21a and a floating channel 21b communicating with the floating space 21a. The floating channel 21b and the floating space 21a are arranged in sequence along the height direction of the box body assembly 10, and the floating space 21a communicates with the water storage cavity 11.

[0063] The floating bottle 30 may include a floating main body 31 and a floating guiding part 32. The floating main body 31 may be a bottle body with a cavity inside. Under the buoyancy of the water in the water storage cavity 11, the floating main body 31 is floatingly arranged in the floating space 21a. The floating guiding part 32 may be a bottleneck extending axially away from the bottle body along the floating bottle 30. The floating guiding part 32 passes through the floating channel 21b. When the floating bottle 30 floats up and down, the floating guiding part 32 is in guiding cooperation with the floating channel 21b, so that the water level detection result is accurate.

[0064] The principle of the floating bottle 30 detecting the water level may be: in the air treatment device 2, a water level alarm matching with the top of the floating bottle 30 is arranged above the water tank 1. During normal use, the amount of water in the water storage cavity 11 is sufficient. Under the buoyancy, the top of the floating bottle 30 presses against the water level alarm, and the water level alarm does not alarm. As the air treatment device 2 is used, the water level in the water storage cavity 11 gradually drops, the floating bottle 30 gradually drops, the connection between the floating bottle 30 and the water level alarm is disconnected, and the water level alarm alarms. At this time, the water level in the water storage cavity 11 is too low, reminding the user to add water.

[0065] One of the floating guide part 32 and the fixed sleeve 21 is provided with a movable channel 2122 extending along the radial direction of the floating bottle 30, and the other is provided with a mating structure 50. For example, the floating guide part 32 is provided with a movable channel 2122 extending along the radial direction of the floating bottle 30, and the mating structure 50 is arranged on the fixed sleeve 21; or, the fixed sleeve 21 is provided with a movable channel 2122 extending along the radial direction of the floating bottle 30, and the mating structure 50 is arranged on the floating guide part 32. The limiting component 40 is telescopically arranged in the movable channel 2122. At least part of the structure of the limiting component 40 (such as the locking pin 41 below) moves between a first position and a second position. When at least part of the structure of the limiting component 40 is in the first position, the limiting component 40 is in limit cooperation with the mating structure 50, so that the floating bottle 30 is limited by the limiting component 40 and floats within a preset range, avoiding the floating bottle 30 deviating from the preset position; when at least part of the structure of the limiting component 40 is in the second position, the limiting component 40 is separated from the mating structure 50, and the floating bottle 30 is disconnected from the fixed sleeve 21. At this time, the floating bottle 30 can be conveniently disassembled for cleaning the floating bottle 30.

[0066] For the water tank 1 of the present utility model, since the limiting component 40 expands and contracts along the radial direction of the floating bottle 30, when it is necessary to clean the floating bottle 30, the user only needs to apply an axial force towards the floating main body 31 to the floating guide part 32, and the mating structure 50 squeezes the limiting component 40 to contract along the movable channel 2122, so that the floating bottle 30 is disconnected from the fixed sleeve 21, and the floating bottle 30 can be disassembled for cleaning. In this way, the operation of disassembling the floating bottle 30 is simple and convenient. When it is necessary to install the floating bottle 30, the user only needs to align the floating guide part 32 with the floating channel 21b, and apply an axial force towards the floating guide part 32 to the floating main body 31 of the floating bottle 30, and push the floating bottle 30 to the position where the mating structure 50 is in limit cooperation with the limiting component 40. The installation is convenient, the structure is simple, and it is easy to implement.

[0067] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , in some embodiments, the bracket assembly 20 may further include a filter element mounting rack 22, the filter element mounting rack 22 is arranged outside the fixed sleeve 21, and the filter element mounting rack 22 is fixedly connected to the fixed sleeve 21 through a connecting rod; the water tank 1 may further include a filtering member 60, the filtering member 60 may be a filter cotton, a filter net, etc., and the filtering member 60 is sleeved on the filter element mounting rack 22.

[0068] On the one hand, the impurities contained in the water in the water tank 1 are filtered by the filter element 60, thereby improving the user experience. In addition, in order to facilitate the disassembly operation of the floating bottle 30, the support assembly 20 of this embodiment can be directly placed at the bottom of the water storage cavity 11. When the floating bottle 30 needs to be replaced, the user can directly lift the support assembly 20. Thus, it is necessary to ensure that the position of the support assembly 20 in the vertical direction is accurate to ensure the accuracy of the water level detected by the floating bottle 30. By providing the filter element mounting frame 22 and the filter element 60, the filter element 60 absorbs water during the filtering process, increasing the weight of the support assembly 20, so that the support assembly 20 can be directly placed at the bottom of the water storage cavity 11, avoiding the change of the position of the support assembly 20 under the buoyancy of the floating bottle 30 and improving the reliability of the detection result.

[0069] Reference Figure 2 、 Figure 4 、 Figure 6 And Figure 7 In some embodiments, the fixed sleeve 21 may include a sleeve main body 211 and a mounting seat 212. The sleeve main body 211 may be a cylindrical structure with an opening at one end (such as Figure 1 the bottom end in

[0070] ). The sleeve main body 211 defines a floating space 21a, which communicates with the water storage cavity 11. The top wall of the sleeve main body 211 is provided with a movable hole 2111, and the movable hole 2111 is opposite to the opening. The mounting seat 212 is arranged on the top of the sleeve main body 211, and the mounting seat 212 defines a floating channel 21b, and the floating channel 21b communicates with the floating space 21a through the movable hole 2111. During the installation of the floating bottle 30, the user installs the floating bottle 30 from the opening of the sleeve main body 211, and sequentially passes the floating guiding portion 32 of the floating bottle 30 through the movable hole 2111 and the floating channel 21b to complete the installation.

[0071] By setting the fixed sleeve 21 into two parts, namely the sleeve main body 211 and the mounting seat 212, the floating main body 31 of the floating bottle 30 is arranged in the sleeve main body 211, and the floating guiding portion 32 passes through the mounting seat 212, playing a guiding role, limiting the floating bottle 30 to only lift and lower along the floating channel 21b to detect the water level in the water storage cavity 11, avoiding the inclination of the floating bottle 30 and causing false detection results, and making the water level detection result accurate.

[0072] Reference Figure 2 、 Figure 4 、Figure 6 and Figure 7 Further, when the mounting base 212 and the sleeve body 211 are detachably connected, one of the mounting base 212 and the sleeve body 211 is provided with a tongue 2124, and the other is provided with a slot. For example, the mounting base 212 is provided with a tongue 2124, and the slot is formed in the outer wall of the top end surface of the sleeve body 211, or the sleeve body 211 is provided with a tongue 2124, and the slot is formed in the lower end surface of the mounting base 212. The tongue 2124 is clamped in the slot to realize the connection between the mounting base 212 and the sleeve body 211.

[0073] Further, the tongue 2124 may be provided with a protrusion protruding radially along the floating bottle 30. One of the protrusion or the tongue 2124 may be elastic, so as to facilitate passing through the slot when inserting into the slot. After passing through the slot, the protrusion abuts against the outer wall of the side of the slot away from the tongue 2124 to fix and limit the mounting base 212.

[0074] It can be understood that the tongue 2124 and the slot can be set in multiple groups and arranged at intervals along the circumferential direction of the mounting base 212 to improve the fixing effect of the mounting base 212 mounted on the sleeve body 211. For example, the cooperation between the tongue 2124 and the slot can be set in 4 groups and arranged at intervals of 90 degrees along the circumferential direction of the mounting base 212. Of course, the cooperation between the tongue 2124 and the slot can also be set in other quantities, and the present application does not limit this.

[0075] Reference Figure 3 and Figure 4 According to some embodiments of the present utility model, an installation portion 2121 extending radially outward along the floating bottle 30 is provided inside the mounting base 212, and the installation portion 2121 defines a moving channel 2122. By providing the installation portion 2121 extending radially outward along the floating bottle 30, on the one hand, the telescopic direction of the telescopic assembly is limited, which is convenient for cooperation with the cooperation structure 50, and on the other hand, a storage space is provided for the telescopic assembly, so that the telescopic assembly can be stored in the installation portion 2121.

[0076] Reference Figure 3 and Figure 4 Further, the mounting base 212 may include: a first side plate 212a, a second side plate 212b and a transition connecting plate 212c. The first side plate 212a and the second side plate 212b are spaced apart along the radial direction of the floating bottle 30. The transition connecting plate 212c is respectively connected to one ends of the first side plate 212a and the second side plate 212b away from the sleeve body 211. The second side plate 212b defines a floating channel 21b and a moving channel 2122. The tongue 2124 is provided on the first side plate 212a, and one end of the second side plate 212b away from the transition connecting plate 212c abuts against the bottom wall of the sleeve body 211.

[0077] The mounting seat 212 is configured as a structure composed of a first side plate 212a, a second side plate 212b and a transition connecting plate 212c. On the one hand, it is easy to design and process, and on the other hand, a cavity is formed between the first side plate 212a and the second side plate 212b. In other words, the mounting seat 212 forms a U-shaped bracket with an opening facing downward and extending circumferentially along the sleeve body 211, which is conducive to saving raw materials, thereby reducing costs and reducing the overall weight.

[0078] refer to Figure 6 and Figure 7 According to some embodiments of the present invention, the matching structure 50 includes a first limiting ring 51 and a second limiting ring 52 which are arranged on the floating guide portion 32 along the axial direction of the floating bottle 30 at intervals.

[0079] When at least part of the structure of the limiting assembly 40 (for example, the locking pin 41 described below) is in the first position, in a first reference plane perpendicular to the axis of the float bottle 30, the projection of the above-mentioned at least part of the structure coincides with the projections of the first limiting ring 51 and the second limiting ring 52 in the first reference plane, respectively. In other words, at this time, when the float bottle 30 is moved up and down along the floating space 21a under the action of buoyancy, it will interfere with the above-mentioned at least part of the structure in the first position during the movement, so that the limiting assembly 40 limits the float bottle 30 to prevent the float bottle 30 from falling off the fixed sleeve 21 during use.

[0080] When the above-mentioned at least partial structure is in the second position, the projection of the above-mentioned at least partial structure in the first reference plane is staggered with the projections of the first limit ring 51 and the second limit ring 52 in the first reference plane respectively. In other words, at this time, when the floating bottle 30 is moved up and down along the floating space 21a by the action of external force, it will not interfere with the above-mentioned at least partial structure in the second position during the movement, so it is convenient to disassemble the floating bottle 30.

[0081] refer to Figure 2 , Figure 6 and Figure 7 According to some embodiments of the present invention, the aperture of the movable hole 2111 is not less than the outer diameter of any one of the first limiting ring 51 and the second limiting ring 52. In other words, the aperture of the movable hole 2111 exceeds the outer diameters of the first limiting ring 51 and the second limiting ring 52, respectively, so that the first limiting ring 51 and the second limiting ring 52 can both be installed through the movable hole 2111, which is beneficial to improving the reliability of the structure.

[0082] refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 According to some embodiments of the present invention, the limiting assembly 40 may include: a locking pin 41 and an elastic member 42 .

[0083] The locking pin 41 is telescopically arranged in the moving channel 2122. The locking pin 41 is adapted to be between a first position and a second position. In this embodiment, at least part of the structure of the above-mentioned limiting component 40 can be the locking pin 41, or at least part of the structure of the above-mentioned limiting component 40 can also be the end of the locking pin 41 facing the floating bottle 30.

[0084] When in the first position, the end of the locking pin 41 facing the floating bottle 30 is located between the first limiting ring 51 and the second limiting ring 52, so as to limit the radial movement of the floating bottle 30. When in the second position, the end of the locking pin 41 facing the floating bottle 30 is located outside the first limiting ring 51 and the second limiting ring 52, and does not limit the radial movement of the floating bottle 30, which is convenient for disassembly.

[0085] The elastic member 42 is arranged in the moving channel 2122. The elastic member 42 is sleeved outside the locking pin 41 and is respectively connected to the channel wall of the moving channel 2122 and the locking pin 41, providing a pressure towards the floating bottle 30 for the locking pin 41 and providing a reset force for the locking pin 41 to move from the second position to the first position. Optionally, the elastic member 42 can be a compression spring, or an elastic sleeve such as a rubber sleeve or a plastic sleeve. In this way, both cost is saved and installation is convenient.

[0086] Through the cooperation of the elastic member 42 and the locking pin 41, when the floating bottle 30 is installed, the user or worker applies an axial force to the floating bottle 30. The first limiting ring 51 on the floating bottle 30 squeezes the elastic member 42 and the locking pin 41 to contract in the moving channel 2122. At this time, the locking pin 41 is in the second position. Continuing to push the floating bottle 30, the locking pin 41 is reset to the first position under the action of the elastic member 42. At this time, the end of the locking pin 41 facing the floating bottle 30 is located between the first limiting ring 51 and the second limiting ring 52, limiting the position of the floating bottle 30 and completing the installation; when disassembling, the user or worker applies an axial force in the opposite direction to the floating bottle 30. The first limiting ring 51 on the floating bottle 30 squeezes the elastic member 42 and the locking pin 41 to contract in the moving channel 2122. At this time, the locking pin 41 is in the second position. Continuing to press the floating bottle 30, the locking pin 41 is reset to the first position under the action of the elastic member 42, and the floating bottle 30 is disconnected from the fixed sleeve 21, completing the disassembly of the floating bottle 30.

[0087] It can be understood that the locking pin 41 and the moving channel 2122 can be set in multiple groups and arranged at intervals along the circumferential direction of the floating bottle 30 to achieve the limiting cooperation effect between the locking pin 41 and the matching structure 50. For example, the locking pin 41 and the moving channel 2122 can be set in two groups and arranged at an interval of 90 degrees along the circumferential direction of the floating bottle 30. Of course, the number of the locking pin 41 and the moving channel 2122 can be set according to requirements, and the present application does not limit this.

[0088] Reference Figure 5, Further, a connecting ring plate 411 is provided on the outer side wall of the locking pin 41. One end of the elastic member 42 is connected to the inner wall of the movable channel 2122 facing the floating bottle 30, and the other end is connected to the connecting ring plate 411.

[0089] By providing the connecting ring plate 411, a force application surface is provided for the elastic member 42, which is beneficial to improving the reliability of the structure. At the same time, the connecting ring plate 411 is processed on the outer wall of the locking pin 41, and the structure is simple and the processing is convenient.

[0090] Reference Figure 3 , Figure 4 and Figure 5 , According to some embodiments of the present invention, a through hole is provided on the inner wall of the movable channel 2122 facing the floating bottle 30. One end of the locking pin 41 away from the floating bottle 30 is inserted through the through hole; an installation limiting structure 412 is provided at one end of the locking pin 41 away from the floating bottle 30, and the installation limiting structure 412 is configured to be in limiting cooperation with the through hole.

[0091] One end of the locking pin 41 away from the avoidance structure slides through the through hole, so that during the installation and disassembly of the floating bottle 30, when the locking pin 41 moves to the second position under the extrusion of the first limiting ring 51, the locking pin 41 has a longer moving stroke, which facilitates the installation and disassembly of the floating bottle 30, avoids the collision between one end of the locking pin 41 away from the floating bottle 30 and the movable channel 2122, and improves the reliability of the structure.

[0092] The installation limiting structure 412 includes a limiting platform 4121. The limiting platform 4121 includes a first end 4121a axially away from the floating bottle 30 and a second end 4121b close to the floating bottle 30. The outer diameter of the first end 4121a is smaller than the through hole, the outer diameter gradually increases from the first end 4121a to the second end 4121b, the outer diameter of the second end 4121b exceeds the through hole, and the side wall of the second end 4121b abuts against the side wall of the installation part 2121 away from the floating bottle 30.

[0093] When the locking pin 41 is installed in the through hole, in the movable channel 2122, the first end 4121a is directed towards the through hole, an axial force is applied to the locking pin 41, and the limiting platform 4121 passes through the through hole, so that the second end 4121b is located on the side of the installation part 2121 away from the floating bottle 30. At this time, the side wall of the second end 4121b abuts against the side wall of the installation part 2121 away from the floating bottle 30, limiting the further movement of the locking pin 41 towards the floating bottle 30 after moving to the first position, avoiding interference and collision between the locking pin 41 and the floating bottle 30, resulting in damage to the floating bottle 30, and being beneficial to further improving the reliability of the structure.

[0094] To prevent the limit platform 4121 from passing through the installation part 2121 and being damaged, one end of the through hole close to the limit platform 4121 can be set as a reamed hole. The diameter of the reamed hole exceeds the diameter of the second end 4121b, and the depth of the reamed hole along the axial direction of the locking shaft exceeds the length from the first end 4121a to the second end 4121b of the limit platform 4121, which is convenient for accommodating the limit platform 4121 in the reamed hole and prolonging the service life of the limit platform 4121.

[0095] Reference Figure 5 , Further, a deformation groove 4122 is defined at the first end 4121a of the limit platform 4121. The deformation groove 4122 extends along the axial direction of the locking shaft towards the second end 4121b. By providing the deformation groove 4122, a deformation margin for the second end 4121b of the limit platform 4121 to deform radially along the locking shaft is provided. When the locking pin 41 is assembled into the through hole, it can contract and deform inward under the extrusion of the inner wall of the through hole to pass through the through hole. After passing through the through hole, the second end 4121b resets to play a limiting role for the locking pin 41. The structure is simple and the installation is convenient.

[0096] Furthermore, the deformation groove 4122 can be a U-shaped groove, and the bottom wall and the two side walls of the U-shaped groove are connected by arc surfaces for transition, reducing stress concentration and prolonging the service life of the limit platform 4121.

[0097] The disassembly and assembly principle of the floating bottle 30 of the water tank 1 of the present utility model is as follows:

[0098] When installing the floating bottle 30, the user lifts the bracket assembly 20, passes the floating guide part 32 of the floating bottle 30 through the opening at the bottom of the fixed sleeve 21, and sequentially passes through the movable hole 2111 and the floating channel 21b. The user applies an axial force towards the floating guide part 32 to the floating bottle 30. When the first limiting ring 51 on the floating bottle 30 passes through the movable channel 2122, it squeezes the elastic member 42 and the locking pin 41 contracts in the movable channel 2122. At this time, the locking pin 41 is in the second position. Continuing to push the floating bottle 30, the locking pin 41 resets to the first position under the action of the elastic member 42. At this time, one end of the locking pin 41 facing the floating bottle 30 is located between the first limiting ring 51 and the second limiting ring 52 to limit the position of the floating bottle 30, completing the installation. Then, the bracket assembly 20 can be placed into the water storage cavity 11.

[0099] When disassembling the floating bottle 30, the user lifts the bracket assembly 20 and applies a pressure along the axis towards the floating body 31 to the floating guide portion 32 of the floating bottle 30. When the first limit ring 51 passes through the movable channel 2122, it squeezes the elastic member 42 and the locking pin 41 contracts in the movable channel 2122. At this time, the locking pin 41 is in the second position. Continuing to press the floating bottle 30, the first limit ring 51 moves away from the movable channel 2122, and the locking pin 41 resets to the first position under the action of the elastic member 42. The floating bottle 30 is disconnected from the fixed sleeve 21, and the disassembly of the floating bottle 30 is completed.

[0101] Due to the use of the above-mentioned water tank 1, when disassembling the floating bottle 30, only an axial pressing force along the floating bottle 30 needs to be applied to the floating bottle 30, and the disassembly of the floating bottle 30 can be completed, which is convenient to operate.
