[0048] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Example 1

[0050] This embodiment provides a water tank assembly structure. In one implementation, as Figures 1 to 10 shown, the water tank assembly structure includes a water tank structure, a fuselage, and a knob 3.

[0051] Among them, the water tank structure is provided with an installation part 202; the fuselage has a base 1, the fuselage is rotatably arranged on the water tank structure, and has a first position in a free state and a second position suitable for locking with the water tank structure. A first locking part is provided on the base 1; the knob 3 is rotatably arranged in the installation part 202, and has a locking state in which it cooperates with the first locking part to lock the fuselage in the second position, and an unlocking state in which it leaves the first locking part.

[0052] For the water tank assembly structure provided in this implementation, during assembly, first install the fuselage base 1 on the water tank, and then rotate the base 1 so that the base 1 rotates to the second position. By rotating the knob 3, the base 1 is locked in the second position. During assembly, the knob 3 can be hidden at the back, making the front of the water tank structure look without protrusions or depressions, and the appearance is more beautiful. At the same time, since the water tank structure and the fuselage can be separated, it is convenient for users to clean the water tank structure, and it has a large volume and does not require frequent water addition.

[0053] Based on the above implementation, in one implementation, the knob 3 is provided with a second locking part. When the knob 3 is in the locking state and the fuselage is in the second position, the second locking part cooperates with the first locking part to prevent the fuselage from rotating towards the first position. In this implementation, by setting the second locking part, the second locking part can be driven to rotate during the process of rotating the knob 3, and the structural size of the second locking part can be set to be smaller without interfering with the rotation of the base 1.

[0054] Based on the above implementation, in one implementation, as Figure 5 shown, the outer peripheral wall of the base 1 is provided with a concave cavity with openings facing downwards and outwards at the same time. The concave cavity has a first cavity wall 103, and the first locking part includes the first cavity wall 103; when the knob 3 is in the locking state, the second locking part is located in the concave cavity and abuts against the first cavity wall 103. In this implementation, when the fuselage needs to be locked, by rotating the knob 3, the second locking part enters the concave cavity through the opening at the lower end of the concave cavity, and the second locking part abuts against the first cavity wall 103, combined with Figure 5, when the second locking part abuts against the first cavity wall 103, it can prevent the base 1 from rotating counterclockwise, that is, prevent the base 1 from rotating to the first position; when it is necessary to separate the fuselage from the water tank structure, rotate the knob 3 to make the second locking part leave the concave cavity, and the base 1 can rotate to the first position. When rotated to the first position, the fuselage and the water tank structure can be separated. The structure is simple and convenient for manual operation. In an alternative embodiment, the first locking part may include a first engaging part, and the second locking part may include a second engaging part. The locking of the base 1 is achieved through the cooperation of the first engaging part and the second engaging part.

[0055] Based on the above embodiment, in one embodiment, as Figure 7 and Figure 8 shown, the second locking part includes an arc-shaped limiting part 301, which has a first side surface 3011 and a second side surface 3012. The central angle between the first side surface 3011 and the second side surface 3012 is 90°. A limiting surface 203 is provided at the inner end of the mounting part 202. When the knob 3 is in the unlocked state, the first side surface 3011 abuts against the limiting surface 203. When the knob 3 is in the locked state, the second side surface 3012 abuts against the limiting surface 203, and the outer wall of the arc-shaped limiting part 301 abuts against the first cavity wall 103. In this embodiment, the setting of the limiting surface 203 enables the knob 3 to only rotate between two positions, which can prevent the user from over-rotating and is more convenient for the user to operate. In other alternative embodiments, the limiting surface 203 may not be provided.

[0056] Based on the above embodiment, in one embodiment, as Figure 9 shown, the knob 3 is provided with an elastic cantilever 302, and a spring post 303 is provided on the elastic cantilever 302. As Figure 7 shown, a contact wall 204 is provided inside the mounting part 202, and the central angle corresponding to the contact wall 204 is 90°. The spring post 303 is adapted to abut against the contact wall 204. In this embodiment, when the knob 3 rotates to the unlocked state or the locked state, there will be an obvious feeling of reaching the rotation position, which is beneficial to improving the user experience.

[0057] Based on the above embodiment, in one embodiment, a limiting groove 205 is provided on the inner wall of the mounting part 202. The limiting groove 205 extends along the circumferential direction of the mounting part 202, and the central angle corresponding to the limiting groove 205 is greater than or equal to 90°. The knob 3 is provided with a convex block 304, and the convex block 304 is arranged in the limiting groove 205. The cooperation of the limiting groove 205 and the convex block 304 can prevent the knob 3 from detaching from the mounting part 202.

[0058] Based on the above embodiment, in one embodiment, a handle 305 is provided at the outer end of the knob 3. The user can hold the handle 305 to rotate the knob 3, which is convenient for the user to operate and further improves the user experience.

[0059] Based on the above embodiments, in one embodiment, at least one notch 201 is provided on the water tank structure. As Figure 10 shown, at least one boss 401 is provided on the inner wall of the water tank structure, and a tongue 101 is provided on the base 1. The tongue 101 is adapted to be inserted into the notch 201, and when the fuselage is in the second position, the tongue 101 is supported below the boss 401. In this embodiment, when the fuselage is in the second position, the tongue 101 is supported below the boss 401, which can prevent the water tank structure from falling off the fuselage when carrying the water tank assembly structure.

[0060] Based on the above embodiments, in one embodiment, a convex column 402 extending downward is provided at the lower end of the boss 401, and a card slot 102 with an upward opening is provided on the tongue 101. When the fuselage is in the second position, the convex column 402 is snapped into the card slot 102. In this embodiment, since the convex column 402 is stuck in the card slot 102, it can limit the position of the water tank structure in the radial direction and prevent the tongue 101 from leaving the lower end of the boss 401 when the water tank structure expands and deforms outward. Therefore, the assembly stability of the water tank assembly structure is further ensured.

[0061] Based on the above embodiments, in a preferred embodiment, there are two bosses 401, and the two bosses 401 are arranged oppositely. One boss 401 is provided on the front side of the water tank structure, and the other boss 401 is provided on the rear side of the water tank structure. Correspondingly, there are two tongues 101. In this embodiment, the water tank structure and the base 1 are connected by the cooperation of two tongues 101 and bosses 401, which can further ensure the assembly stability of the water tank assembly structure. In other alternative embodiments, the number of notches 201 can be set to 3, and correspondingly, the number of bosses 401 is set to 3, and the number of tongues 101 is set to 3.

[0062] Based on the above embodiments, in a preferred embodiment, the mounting portion 202 is provided at the position of the boss 401 near the rear side of the water tank structure. In this embodiment, there is no pit or protrusion at the front end of the water tank structure, and the appearance is beautiful.

[0063] Based on the above embodiments, in a preferred embodiment, the water tank structure includes a water tank body 4 and a decorative ring 2. The notch 201 and the mounting portion 202 are provided on the decorative ring 2. Specifically, a circular groove with a downward opening is provided on the decorative ring 2, and the upper end of the water tank body 4 is embedded in the circular groove. The decorative ring 2 can be easily installed on the water tank body 4. The setting of the decorative ring 2 can not only make the appearance more beautiful, but also facilitate processing when the notch 201 and the mounting portion 202 are both processed on the decorative ring 2.
