[0030] In the present application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation described as "exemplary" in the present application is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the present application. In the following description, for the purposes of explanation, numerous details are set forth. It should be appreciated that one of ordinary skill in the art will realize that the present application can be practiced without the use of these specific details. In other instances, well known structures and processes are not elaborated in order not to obscure the description of the present application with unnecessary detail. Thus, the present application is not intended to be limited by the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0031] As Figures 1 to 4 shown, in one aspect, the embodiment of the present application provides a liquid level detection device, which comprises a fixing plate 1, a sensor mounting seat 2 and a liquid level sensor 3, can make the liquid level sensor 3 stably rotate and adjust, and ensure the structural safety of the liquid level sensor 3 in the rotating process.

[0032] The fixing plate 1 is used for installing and fixing the sensor mounting seat 2, and the sensor mounting seat 2 is arranged on the fixing plate 1. The sensor mounting seat 2 has a rotating shaft clamping part 21 and an assembly through hole 22, and the assembly through hole 22 and the rotating shaft clamping part 21 are arranged adjacent to each other. The liquid level sensor 3 comprises a rotating connection shaft 31 and a liquid level sensing shaft 32, the liquid level sensing shaft 32 is connected to the peripheral wall of the rotating connection shaft 31, the rotating shaft clamping part 21 and the rotating connection shaft 31 of the liquid level sensor 3 are rotationally connected, and the liquid level sensing shaft 32 is rotationally arranged in the assembly through hole 22 around the axis of the rotating shaft clamping part 21.

[0033] In this way, the hole wall of the assembly through hole 22 can limit the liquid level sensing shaft 32, and when the liquid level sensor 3 is rotationally adjusted, the hole wall of the assembly through hole 22 can constrain and limit the rotating stroke of the liquid level sensor 3, so as to avoid the liquid level sensor 3 from shaking violently due to excessive rotation, and further avoid the liquid level sensor 3 from being structurally damaged due to violent shaking, thereby ensuring the structural safety of the liquid level sensor 3 in the rotating process. When the sensor mounting seat 2 is applied to the ducted fan machine, the ducted fan machine can be switched between the horizontal installation mode and the vertical installation mode.

[0034] As Figure 5 shown, in some embodiments, the liquid level sensor 3 can comprise a float 34 arranged on the liquid level sensing shaft 32. The float 34 floats on the liquid surface and can rise and fall with the change of the liquid level, so that the position of the float 34 and the sensing part of the liquid level sensing shaft 32 changes. In this way, the sensing part of the liquid level sensing shaft 32 can measure the position change of the float 34, and further indirectly measure the change of the liquid level by measuring the position change of the float 34.

[0035] In some embodiments, the liquid level sensor 3 can further comprise a counterweight 35 arranged on the liquid level sensing shaft 32; by arranging the counterweight 35, the self-weight of the liquid level sensor 3 can be increased, and the liquid level sensor 3 can be adaptively adjusted under the action of the self-weight.

[0036] In some embodiments, the liquid level sensor 3 can further include a limiting member 36. The liquid level sensing shaft 32 can be provided with a limiting groove 321 at an end away from the rotating connecting shaft 31, and the limiting member 36 can be clamped in the limiting groove 321. When the liquid level sensing shaft 32 is sleeved with components such as the float 34, the counterweight 35, etc., the limiting member 36 can limit the components between the limiting member 36 and the rotating connecting shaft 31. The type of the limiting member 36 can be determined according to actual needs, and can be of a type such as a snap spring, which is not limited in the embodiments of the present application.

[0037] In some embodiments, the rotating connecting shaft 31 can include a shaft body 312 and two connecting necks 313. The liquid level sensing shaft 32 is connected to the peripheral wall of the shaft body 312, and the two connecting necks 313 are arranged at opposite ends of the shaft body 312. The sensor mounting seat 2 can be provided with a plurality of rotating shaft clamping portions 21, which can be arranged on opposite sides of the assembly through hole 22. The two connecting necks 313 are rotatably clamped in different rotating shaft clamping portions 21, so that the plurality of rotating shaft clamping portions 21 can be rotatably connected on opposite sides of the assembly through hole 22 and the two connecting necks 313, respectively, to balance and stably support the liquid level sensor 3, thereby improving the reliability of the rotating connection between the liquid level sensor 3 and the sensor mounting seat 2. The shaft body 312 is partially embedded in the assembly through hole 22, so that the shaft body 312 can rotate in the assembly through hole 22, avoiding obstruction of the rotation of the liquid level sensor 3, and ensuring the smoothness of the rotation of the liquid level sensor 3.

[0038] As shown in FIG. 1, Figures 1 to 7 In some embodiments, the rotating connecting shaft 31 can be provided with a wire routing cavity 311, which is open at one end of the rotating connecting shaft 31 and at the other end of the peripheral wall of the rotating connecting shaft 31 in a region connected to the liquid level sensing shaft 32. The liquid level sensor 3 can include a signal line 33, which passes through the wire routing cavity 311 to electrically connect to a sensing portion (not shown in the figure) of the liquid level sensing shaft 32, to provide a power signal to the sensing portion and to transmit an electrical signal measured by the sensing portion outward. In this way, when the liquid level sensor 3 is adjusted in rotation, the signal line 33 can rotate synchronously with the rotating connecting shaft 31, avoiding obvious relative movement between the signal line 33 and the rotating connecting shaft 31, and further avoiding damage to the signal line 33 caused by the relative movement, thereby effectively ensuring the structural safety of the liquid level sensor 3 during rotation.

[0039] The structure of the wiring cavity 311 can be determined according to actual needs, and embodiments of the present application do not limit this. In some examples, the wiring cavity 311 can include a first cavity portion 3111 and a second cavity portion 3112 that are sequentially communicated. The first cavity portion 3111 is open at one end of the rotating connection shaft 31 and extends along the axial direction of the rotating connection shaft 31. The second cavity portion 3112 is open at a region of the rotating connection shaft 31 connecting the liquid level sensing shaft 32 on the peripheral wall of the rotating connection shaft 31 and extends along a first direction, which is perpendicular or inclined to the axial direction of the rotating connection shaft 31. In this way, the signal line 33 can enter the first cavity portion 3111 from the open end of the first cavity portion 3111, sequentially pass through the first cavity portion 3111 and the second cavity portion 3112, and then pass out from the open end of the second cavity portion 3112, thereby being electrically connected to the sensing portion of the liquid level sensing shaft 32.

[0040] The type of the signal line 33 can be determined according to actual needs, and embodiments of the present application do not limit this. In some examples, the signal line 33 can include a plurality of core wires 331 and an insulating sheath 332. The plurality of core wires 331 are insulatively arranged in the insulating sheath 332, and the plurality of core wires 331 are wrapped, constrained and protected by the insulating sheath 332; and the plurality of core wires 331 pass through the wiring cavity 311 to be electrically connected to the sensing portion of the liquid level sensing shaft 32 to provide a power signal to the sensing portion and transmit an electrical signal measured by the sensing portion outward. Here, the insulating sheath 332 is spaced apart from the rotating connection shaft 31, so that the insulating sheath 332 is not connected to the rotating connection shaft 31. In this way, when the rotating connection shaft 31 drives the liquid level sensing shaft 32 to rotate and adjust, the insulating sheath 332 will not rotate and twist, thereby avoiding damage to the plurality of core wires 331 caused by twisting of the insulating sheath 332, and ensuring the structural safety of the plurality of core wires 331 during rotation of the liquid level sensor 3.

[0041] For example, the insulating sheath 332 can be arranged outside the wiring cavity 311. In other words, the insulating sheath 332 can wrap the portion of the plurality of core wires 331 outside the wiring cavity 311, and the insulating sheath 332 is spaced apart from the rotating connection shaft 31, so that the insulating sheath 332 can movably wrap the outside of the plurality of core wires 331. In this way, when the rotating connection shaft 31 drives the liquid level sensing shaft 32 to rotate and adjust, the insulating sheath 332 will not be subjected to the rotating force of the rotating connection shaft 31, so that the insulating sheath 332 will not rotate and twist; thereby avoiding damage to the plurality of core wires 331 caused by twisting of the insulating sheath 332, and ensuring the structural safety of the plurality of core wires 331 during rotation of the liquid level sensor 3.

[0042] In some embodiments, the rotating connection shaft 31 and the liquid level sensing shaft 32 can be connected vertically or obliquely. In this way, the liquid level sensing shaft 32 can be arranged vertically or obliquely on the lower side of the rotating connection shaft 31; after the rotating connection shaft 31 is rotatably connected to the sensor mounting member, the liquid level sensing shaft 32 can be in contact with the liquid medium, thereby measuring the liquid level of the liquid medium. In some examples, the liquid level sensing shaft 32 can be connected to the middle region of the rotating connection shaft 31 along the axial direction of the rotating connection shaft 31.

[0043] In some embodiments, the sensor mounting seat 2 can include a first mounting plate 23 and a second mounting plate 24 connected to each other, and the first mounting plate 23 and the second mounting plate 24 are vertical or oblique. The rotating shaft clamping portion 21 is arranged at the connecting portion of the first mounting plate 23 and the second mounting plate 24, so that the rotating connection shaft 31 can be rotatably connected to the connecting portion of the first mounting plate 23 and the second mounting plate 24. The assembly through hole 22 extends from the first mounting plate 23 to the second mounting plate 24, that is, a part of the assembly through hole 22 is arranged on the first mounting plate 23, and another part of the assembly through hole 22 is arranged on the second mounting plate 24. In this way, the liquid level sensor 3 can rotate between the region of the first mounting plate 23 and the region of the second mounting plate 24 in the assembly through hole 22. When the sensor mounting seat 2 is applied to the ducted air conditioner, if the ducted air conditioner is installed horizontally, the liquid level sensor 3 can be kept in the region of the first mounting plate 23 in the assembly through hole 22, meeting the liquid level detection needs of the ducted air conditioner in the horizontal installation posture; if the ducted air conditioner is installed vertically, the liquid level sensor 3 can be kept in the region of the second mounting plate 24 in the assembly through hole 22, meeting the liquid level detection needs of the ducted air conditioner in the vertical installation posture.

[0044] In some examples, the sensor mounting seat 2 can also be provided with a first wire clamping portion 25. The first wire clamping portion 25 and the rotating shaft clamping portion 21 are arranged on the same side surface of the sensor mounting seat 2, and the first wire clamping portion 25 is located on the side of the rotating shaft clamping portion 21 away from the assembly through hole 22. When the liquid level sensor 3 is provided with a signal line 33, the first wire clamping portion 25 can be used to clamp and fix the signal line 33, so that the signal line 33 can be better routed on the liquid level sensor 3.

[0045] In some examples, the sensor mounting seat 2 can also be provided with a second wire clamping portion 26, which can also be used for clamping and fixing the signal line 33. The first wire clamping portion 25 and the second wire clamping portion 26 can be sequentially and spaced apart along the rotation direction of the liquid level sensor 3, and the second wire clamping portion 26 is located at the edge portion of the sensor mounting seat 2 along the rotation direction of the liquid level sensor 3, and the signal line 33 is sequentially clamped to the first wire clamping portion 25 and the second wire clamping portion 26. In this way, the signal line 33 can be routed through the first wire clamping portion 25, and then extended out of the sensor mounting seat 2 from the second wire clamping portion 26, so that the signal line 33 can be better arranged on the liquid level sensor 3 and extended outward.

[0046] For example, the second wire clamping portion 26 can be protrudingly formed on one side surface of the sensor mounting seat 2 away from the rotating shaft clamping portion 21, and the second wire clamping portion 26 is provided with a wire passing port 261. In this way, the signal line 33 can be extended from the first wire clamping portion 25 to the second wire clamping portion 26, and then extended out of the sensor mounting seat 2 from the wire passing port 261 on the other side surface of the sensor mounting seat 2 away from the rotating shaft clamping portion 21, so that the signal line 33 can be better arranged on the liquid level sensor 3 and extended outward.

[0047] For example, the second wire clamping portion 26 can include an abutting folded edge 262. The abutting folded edge 262 is located at one end edge of the sensor mounting seat 2 along the axial direction of the rotating shaft clamping portion 21, and the wire passing port 261 is formed at one end of the second wire clamping portion 26 away from the abutting folded edge 262. Here, when the sensor mounting seat 2 and the fixed plate 1 are fixedly connected, the abutting folded edge 262 can abut and support the fixed plate 1; at the same time, since the wire passing port 261 and the abutting folded edge 262 are located at opposite ends of the second wire clamping portion 26, the signal line 33 can be extended out of the sensor mounting seat 2 in a direction away from the abutting folded edge 262, and the abutting folded edge 262 can be used to block and protect the signal line 33 arranged on the second wire clamping portion 26, so as to avoid the signal line 33 from being scratched and damaged when the sensor mounting seat 2 and the fixed plate 1 are abutted and installed.

[0048] In some embodiments, the sensor mounting seat 2 can be provided with a plurality of rotating shaft clamping portions 21, which can be arranged on opposite sides of the assembly through hole 22. In this way, the plurality of rotating shaft clamping portions 21 can be rotationally connected to the liquid level sensor 3 on opposite sides of the assembly through hole 22, and can balanceably and stably support the liquid level sensor 3, thereby improving the reliability of the rotational connection between the liquid level sensor 3 and the sensor mounting seat 2.

[0049] In some embodiments, the sensor mounting base 2 can further be provided with a fixed connecting portion 27. The fixed connecting portion 27 is located at one end of the sensor mounting base 2 along the axial direction of the rotating shaft clamping portion 21, and the fixed plate 1 can be provided with a matching through hole (not shown in the figure), and a fastener is fixedly connected to the fixed plate 1 after passing through the matching through hole. The type of the fixed connecting portion 27 can be determined according to actual needs, and types such as threaded holes, pin holes, etc. can be used, which are not limited in the embodiments of the present application.

[0050] In some examples, the sensor mounting base 2 can further be provided with a plurality of fixed connecting portions 27, and the plurality of fixed connecting portions 27 can be sequentially and spaced apart along the rotating direction of the liquid level sensor 3. Correspondingly, the fixed plate 1 can be provided with a plurality of matching through holes. In this way, the plurality of fixed connecting portions 27 are located at one end of the sensor mounting base 2 along the axial direction of the rotating shaft clamping portion 21, and the sensor mounting base 2 can be connected to the fixed plate 1 at multiple points through the plurality of fixed connecting portions 27 and the plurality of matching through holes on the fixed plate 1, so that the sensor mounting base 2 can be reliably mounted on the fixed plate 1.

[0051] On the other hand, the embodiments of the present application provide a ducted air conditioner, which includes a fixed plate 1, a sensor mounting base 2 and a liquid level sensor 3. The fixed plate 1 is used to mount and fix the sensor mounting base 2, and the sensor mounting base 2 is arranged on the fixed plate 1. The sensor mounting base 2 has a rotating shaft clamping portion 21 and an assembly through hole 22, and the assembly through hole 22 and the rotating shaft clamping portion 21 are arranged adjacent to each other. The liquid level sensor 3 includes a rotating connection shaft 31 and a liquid level sensing shaft 32, the liquid level sensing shaft 32 is connected to the peripheral wall of the rotating connection shaft 31, the rotating shaft clamping portion 21 and the rotating connection shaft 31 of the liquid level sensor 3 are rotationally connected, and the liquid level sensing shaft 32 is rotationally arranged in the assembly through hole 22 along the axis of the rotating shaft clamping portion 21.

[0052] The ducted air conditioner provided by the embodiments of the present application has the above-mentioned fixed plate 1, sensor mounting base 2 and liquid level sensor 3. When the liquid level sensor 3 is adjusted in rotation, the hole wall of the assembly through hole 22 can limit the liquid level sensing shaft 32, and when the liquid level sensor 3 is adjusted in rotation, the hole wall of the assembly through hole 22 can constrain and limit the rotating stroke of the liquid level sensor 3, so as to avoid excessive rotation of the liquid level sensor 3 and prevent the liquid level sensor 3 from shaking violently, thereby avoiding structural damage of the liquid level sensor 3 due to violent shaking and ensuring the structural safety of the liquid level sensor 3 during rotation.

[0053] In some embodiments, the fixed plate 1 can be a side sealing plate of the ducted air conditioner. Using the side sealing plate of the ducted air conditioner as the mounting base of the sensor mounting base 2 can simplify the structure of the ducted air conditioner.

[0054] The liquid level detection device and the air duct machine provided by the embodiments of the present application are described in detail above, and the principles and implementation manners of the present application are described by using specific examples. The above description of the embodiments is only used to help understand the method of the present application and its core idea; meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation manners and application ranges will be changed, and the above description of the embodiments should not be understood as a limitation on the present application.
