[0031] In this application, the term "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0032] On the one hand, such as Figures 1 to 4 As shown, this application embodiment provides a water pump mounting structure, including a bracket body 1 and a drive assembly 2; the bracket body 1 is rotatably mounted on the base plate 41 of the air duct machine, and the bracket body 1 is provided with a water pump mounting part 11 and a liquid level switch mounting part 12; the drive assembly 2 is movably mounted on the base plate 41, and the drive assembly 2 is used to drive the bracket body 1 to rotate around a first rotation axis 19, the first rotation axis 19 being perpendicular to the base plate 41.

[0033] Most of the water pumps in ducted air conditioners that are designed for vertical installation cannot be changed along with the installation method and can only remain in the traditional horizontal installation position, which is a waste of unit configuration. When the installation method of the ducted air conditioner is changed, the water level changes. If the water pump remains in the horizontal installation position, it may not be able to be used normally, and there is a certain probability of condensate overflow. A small number of ducted air conditioners can be used by manually disassembling and reinstalling the water pump, but this operation is complicated and difficult for installers.

[0034] In this embodiment, when the duct air conditioner needs to be switched from a vertical installation to a horizontal installation, the installation methods of the water pump and the level switch 42 need to be changed for adaptation. The duct air conditioner can be rotated 90° so that the base plate 41 of the duct air conditioner serves as a side plate. Then, the drive assembly 2 drives the bracket body 1 to rotate around the first rotating axis 19, thereby adjusting the vertical position of the level switch mounting part 12 so that the installation height of the level switch 42 on the level switch mounting part 12 matches the warning control water level when the duct air conditioner is installed horizontally. The above switching process does not require disassembly and assembly of the water pump and the level switch 42, which can adapt the installation method of the water pump and the level switch 42 to the installation method of the duct air conditioner. This setting can ensure the normal use of the water pump, and the operation of switching the water pump installation method is simple and convenient for users.

[0035] In some embodiments, the drive assembly 2 can slide along the first rotation axis 19 between a first position and a second position. The drive assembly 2 engages with the bracket body 1 in the first position to drive the bracket body 1 to rotate. The drive assembly 2 separates from the bracket body 1 in the second position. The bottom of the bracket body 1 is provided with a first positioning part, and the end of the drive assembly 2 facing the bracket body 1 is provided with a second positioning part. The first positioning part and the second positioning part are adapted to engage. When the drive assembly 2 slides to the first position, the second positioning part engages with the first positioning part to drive the bracket body 1 to rotate. When the drive assembly slides from the first position to the second position, the second positioning part gradually separates from the first positioning part.

[0036] Specifically, the drive assembly 2 is first moved from the second position to the first position, allowing the first positioning part to engage with the second positioning part. Then, the drive assembly 2 is rotated to control the rotation of the bracket body 1 until the water pump and level switch 42 are in the appropriate positions. Afterward, the drive assembly 2 is moved to the second position, completing the change in the water pump installation method. This configuration ensures a stable connection between the drive assembly 2 and the bracket body 1, making the rotation of the bracket body 1 more reliable. In other embodiments, the first positioning part and the second positioning part are interlocked.

[0037] In some embodiments, the bottom of the bracket body 1 is provided with a recessed mounting groove 16, and a first positioning part is provided in the mounting groove 16. The first positioning part includes a plurality of first meshing teeth 15 arranged in a ring, and a second positioning part includes a plurality of second meshing teeth 22 arranged in a ring. When the drive assembly 2 slides to the first position, the first meshing teeth 15 and the second meshing teeth 22 engage to make the second positioning part engage with the first positioning part.

[0038] Specifically, multiple first meshing teeth 15 are evenly spaced, and multiple second meshing teeth 22 are distributed corresponding to the first meshing teeth 15. The multiple first meshing teeth 15 together form a first engaging ring, and the multiple second meshing teeth 22 together form a second engaging ring. The first engaging ring and the second engaging ring are interlocked, meaning that any two first meshing teeth 15 can engage with one second meshing tooth 22. This arrangement increases the engagement stability between the first positioning part and the second positioning part, preventing slippage between the bracket body 1 and the drive assembly 2 during rotation. In other embodiments, the first positioning part is a square hole, and the second positioning part is a prism structure, with the prism inserted into the square hole.

[0039] In some embodiments, the first positioning part includes a first sleeve 14, the second positioning part includes a second sleeve 21, a plurality of second meshing teeth 22 are distributed inside the second sleeve 21, the inner diameter of the second sleeve 21 is greater than or equal to the outer diameter of the first sleeve 14, and when the first meshing teeth 15 and the second meshing teeth 22 mesh, the second sleeve 21 is sleeved on the first sleeve 14.

[0040] Specifically, the inner diameter of the second sleeve 21 is greater than or equal to the outer diameter of the first sleeve 14. When the drive assembly 2 is moved to the first position, the second sleeve 21 is fitted onto the first sleeve 14, and the first meshing tooth 15 and the second meshing tooth 22 engage. Since the inner diameter of the second sleeve 21 is close to the outer diameter of the first sleeve 14, the second sleeve 21 can restrict the radial movement of the first sleeve 14. This arrangement ensures that the engagement between the first positioning part and the second positioning part will not be misaligned, and that they are not easily disengaged during engagement, thus improving engagement stability. In some other embodiments, the first meshing tooth 15 and the second meshing tooth 22 are both guide helical teeth, that is, when the first meshing tooth 15 and the second meshing tooth 22 contact, they can guide each other, so that the second meshing tooth 22 quickly inserts into the gap between the two first meshing teeth 15.

[0041] In some embodiments, the drive assembly 2 includes a movable rod 23 and a fixed base 24. The second sleeve 21 is fixed to one end of the fixed base 24, and the movable rod 23 is detachably connected to the other end of the fixed base 24. The movable rod 23 can move axially along the first rotation axis 19 to drive the fixed base 24 to move.

[0042] Specifically, the base plate 41 has a movable hole into which the movable rod 23 can be movably inserted. By controlling the forward and backward movement of the movable rod 23 on the first rotating shaft 19, the engagement and disengagement of the drive assembly 2 and the bracket body 1 are controlled. First, the movable rod 23 is passed through the movable hole, and then the fixed seat 24 is installed on the movable rod 23. The size of the fixed seat 24 is larger than the movable hole. This arrangement ensures that the drive assembly 2 will not detach from the base plate 41. In some other embodiments, the movable rod 23 and the fixed seat 24 are welded together.

[0043] In some embodiments, the pump mounting structure includes a planar bearing 34, which is mounted in the mounting groove 16 and sleeved on the second sleeve 21.

[0044] Specifically, the mounting groove 16 is a circular groove, and the planar bearing 34 is a planar thrust bearing, which can be a needle roller bearing or a ball bearing. The planar bearing 34 is interference-fitted with the mounting groove 16. When in the first position, the second sleeve 21 is inserted into the inner hole of the planar bearing 34. This arrangement makes the connection between the second sleeve 21 and the mounting groove 16, and the connection between the second sleeve 21 and the first sleeve 14, more compact, reducing the friction between the second sleeve 21 and the bracket body 1 when the second sleeve 21 rotates, making the rotation smoother.

[0045] In some embodiments, the movable rod 23 is provided with external threads, and the fixed seat 24 is provided with a threaded hole on the side near the movable rod 23, and the movable rod 23 is screwed into the threaded hole.

[0046] Specifically, the movable rod 23 is a bolt structure, comprising a nut and a screw. The outer diameter of the nut is larger than the inner diameter of the movable hole, and the screw is threaded into a threaded hole on the fixed base 24. This arrangement allows for a detachable connection between the movable rod 23 and the fixed base 24. In other embodiments, one end of the movable rod 23 is provided with an elastic buckle, and the fixed base 24 is provided with a locking interface, into which the elastic buckle engages.

[0047] In some embodiments, the bracket body 1 is provided with an arc-shaped sliding groove 17, and the water pump mounting structure further includes a first plug-in post 31, which passes through the arc-shaped sliding groove 17 and is fixedly plugged into the base plate 41.

[0048] Specifically, one end of the first plug-in post 31 is always connected to the base plate 41. First, the first plug-in post 31 is loosened so that the surface of the first plug-in post 31 is separated from the bracket body 1. The bracket body 1 is rotated to a certain angle. At this time, the first plug-in post 31 can move in the arc-shaped sliding groove 17. Then, the first plug-in post 31 is pressed tightly against the bracket body 1 so that the bracket body 1 is fixed to the base plate 41. This setting can prevent the bracket body 1 from rotating due to its own weight, thereby ensuring the installation stability of the water pump.

[0049] In some embodiments, the base plate 41 is provided with a limiting groove 18, the limiting groove 18 and the arc-shaped groove 17 are spaced apart, the side wall of the limiting groove 18 is provided with a plurality of protrusions 18a, the water pump mounting structure includes a second plug post 32, the second plug post 32 passes through the limiting groove 18 and is located between any two adjacent protrusions 18a, and the second plug post 32 is fixedly plugged into the base plate 41.

[0050] Specifically, a limiting groove 18 is provided on the opposite side of the arc-shaped groove 17. The limiting groove 18 is also arc-shaped, and the centers of the two grooves are concentric. After the bracket body 1 is rotated, the second insertion post 32 can be located between any two adjacent protrusions 18a. At this time, the second insertion post 32 is pressed against the bracket body 1, and the two protrusions 18a can clamp the second insertion post 32. This setting increases the limiting of the bracket body 1 and can further increase the installation stability of the bracket body 1.

[0051] In some embodiments, a first screw and a second screw 33 are provided corresponding to the first plug post 31 and the second plug post 32. The first screw and the second screw 33 pass through the base plate 41 and are screwed to the bottom of the first plug post 31 and the bottom of the second plug post 32 respectively, so as to fix the first plug post 31 and the second plug post 32 to the base plate 41.

[0052] Specifically, both the first and second threaded connectors 33 are bolts, and both the first and second insertion posts 31 and 32 are threaded holes extending along the axial direction. The first and second insertion posts 31 and 32 are located on the side of the bracket body 1 away from the base plate 41. Both the first and second threaded connectors 33 pass through the base plate 41 and are threaded together, thus securing the first and second insertion posts 31 and 32. In other embodiments, both the first and second insertion posts 31 and 32 are provided with external threads, and the first and second threaded connectors 33 are nuts.

[0053] In some embodiments, the bracket body 1 is provided with an extension plate 13, and the liquid level switch mounting part 12 is provided on the extension plate 13. The liquid level switch mounting part 12 is a fixing groove, which is used for mounting the liquid level switch 42.

[0054] Specifically, the support body 1 is connected to an extension plate 13. The edge of the extension plate 13 is provided with a semi-circular fixing groove. The liquid level switch 42 is clamped in the fixing groove. The liquid level switch 42 is used to detect the water level in the air duct machine, thereby controlling the start and stop of the water pump.

[0055] In some embodiments, the bracket body 1, the first positioning part, and the extension plate 13 are integrally formed.

[0056] Specifically, the bracket body 1, the first positioning part, and the extension plate 13 are all made of metal and are integrally cast. This design improves the connection stability of the three bracket components and saves production costs. In other embodiments, the bracket body 1, the first positioning part, and the extension plate 13 are welded together.
