[0065] As Figure 2 , 3 and 4, in the embodiment, a wireless charging mechanism is further included, the wireless charging mechanism includes:

[0066] A charging coil (not shown) is located in the sealed space 211 and electrically connected to the battery 23;

[0067] A first movable seat 25 is movably arranged at the lower part of the liquid storage cavity 11, and a wireless charging unit 2512 is installed on the first movable seat 25. When the first movable seat 25 is adjacent to the charging coil, the battery 23 can be charged.

[0069] In this way, the buoy model 2 can be charged by wireless charging without being taken out for charging.

[0070] In actual use, the movable rod of the first telescopic element 26 is a hollow rod, and the cable of the electronic element on the first movable seat 25 passes through the movable rod of the first telescopic element 26 and then passes out from the part of the movable rod of the first telescopic element 26 located outside the hollow transparent column 1.

[0071] As Figure 2 and 3 shown, in the embodiment, when the bottom of the buoy model 2 is in contact with the bottom wall of the liquid storage cavity 11, the wireless charging unit 2512 and the charging coil are at the same horizontal position.

[0072] As Figure 2 and Figure 4 shown, in the embodiment, the lower part of the outer side of the transparent columnar shell 21 has a first gear 214, and the wireless charging mechanism further includes:

[0073] A second movable seat 27 is movably arranged at the lower part of the liquid storage cavity 11, and a drive gear 271 and a motor assembly (not shown) for driving the drive gear 271 to rotate are installed on the second movable seat 27, and the drive gear 271 is used for cooperating with the first gear 214; and

[0074] A second telescopic element 28, the movable rod of the second telescopic element 28 is slidingly and sealingly arranged on the hollow transparent column 1, and the end of the movable rod of the second telescopic element 28 is fixed to the second movable seat 27.

[0075] The first movable seat 25 and the second movable seat 27 both have an arc-shaped surface 2511 on the side facing the buoy model 2. When the first movable seat 25 and the second movable seat 27 are close to each other, the buoy model 2 can be confined between the two arc-shaped surfaces 2511, and at this time the driving gear 271 and the first gear 214 are engaged with each other.

[0076] In actual use, the movable rod of the second telescopic element 28 is a hollow rod. After the cables of the electronic components on the second movable seat 27 pass through the movable rod of the second telescopic element 28, they pass through the part of the movable rod of the second telescopic element 28 located outside the hollow transparent column 1.

[0077] like Figure 4 As shown, in this embodiment, a magnet 215 is provided on the transparent cylindrical shell 21, and a control circuit for controlling the operation of the motor assembly is provided in the second movable seat 27 (omitted in the figure). The control circuit includes a Hall sensor. When the position of the magnet 215 corresponds to the position of the Hall sensor, the charging coil is aligned with the wireless charging unit 2512.

[0078] A specific working form of the wireless charging mechanism: the buoy model 2 dives to the bottom (the bottom of the buoy model 2 contacts the bottom wall of the liquid storage chamber 11), and then the first telescopic element 26 and the second telescopic element 28 work, so that the first movable seat 25 and the second movable seat 27 are close to each other, and the buoy model 2 can be restricted between the two arc-shaped surfaces 2511, and at this time the driving gear 271 and the first gear 214 are engaged with each other, and the motor assembly works, and drives the buoy model 2 to rotate through the engagement of the driving gear 271 and the first gear 214 until the magnet 215 on the transparent cylindrical shell 21 corresponds to the position of the Hall sensor. At this time, the charging coil is aligned with the wireless charging unit 2512, and accurate wireless charging can be performed.

[0079] like Figure 2 and Figure 4 As shown, in this embodiment, the first movable seat 25 and the second movable seat 27 both have a hard part 251 and an arc-shaped elastic part 252 located on both sides of the hard part 251, the arc surface 2511 is located on the hard part 251, and the arc-shaped elastic part 252 is used to play a guiding role, which can transfer the buoy model 2 between the two hard parts 251 when the first movable seat 25 and the second movable seat 27 approach each other.

[0080] like Figure 2 As shown, in this embodiment, there are two avoidance grooves 12 at the bottom of the liquid storage chamber 11, and the two avoidance grooves 12 correspond one-to-one with the first movable seat 25 and the second movable seat 27. In the initial state, the hard parts 251 of the first movable seat 25 and the second movable seat 27 are respectively located in the corresponding avoidance grooves 12.

[0081] If the avoidance groove 12 is not set, the moving seat will occupy a larger space in the lower part of the liquid storage cavity 11, and when the float model 2 is submerged to the lowest position, it is easy to fall directly above the hard part, causing the wireless charging mechanism to fail to work normally.

[0082] As shown in Figure 2 In the embodiment, the upper end of the transparent columnar shell 21 also has an antenna part 291 and a sensor part 292.

[0083] The above is only the preferred embodiment of the present application, and does not limit the patent protection scope of the present application, and any equivalent structural transformation, direct or indirect application in other related technical fields, is also included in the protection scope of the present application.
