[0043] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, inside, outside, top, bottom, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0045] In the description of the present utility model, "a plurality" refers to two or more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0046] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0047] The water tank of the air conditioner humidifier is generally equipped with a float valve. When the solenoid valve stops working due to a power outage or a fault, the water tank can temporarily control the water inlet through the float valve. The float valve is provided with a rotatable transmission part, and the transmission part is provided with a floating part. When the water level in the water tank drops, the floating part floats and drives the transmission part to rotate, and the transmission part then drives the float valve to open, thereby achieving water inlet. When the water level in the water tank rises to a preset position, the floating part floats and drives the transmission part to rotate, and the transmission part then drives the float valve to close, thereby stopping water inlet.

[0048] In order to make the floating part receive the pressure of the liquid more uniformly and have better stability, some floating parts are set to be cylindrical. In this way, when the floating part floats up and drives the transmission part to rotate, the floating part will swing along, and the end of the floating part away from the transmission part will tilt upward relative to the water surface, so that it is easy to touch the top plate of the water tank.

[0049] Due to reasons such as installation space, it is inconvenient to increase the height of the water tank. In related technologies, this problem is generally solved by reducing the rotatable angle of the transmission member. In this way, the floating stroke of the floating part will be reduced accordingly, resulting in low utilization of the water tank and less water that can be stored.

[0050] To this end, the utility model proposes a float valve assembly, a water tank, a humidifier and an air conditioner, which can effectively improve the above problems.

[0051] Reference below Figures 1 to 5 The present invention describes a float valve assembly, a water tank, a humidifier and an air conditioner according to the embodiments of the present invention.

[0052] refer to Figures 1 to 5 As shown, the float valve assembly according to the first embodiment of the utility model is applied to a water tank, and includes a valve seat 100 , a valve core 200 , a transmission member 300 and a floating part 400 .

[0053] Among them, reference Figures 1 to 3 and Figure 5 As shown, the valve seat 100 can be installed on the water tank body 500 or the water inlet pipe. There are many ways to install the valve seat 100. For example, the valve seat 100 can be provided with a threaded column 103, and the threaded column 103 can be sleeved with a nut 104. The water tank body 500 can be provided with a mounting hole, and the threaded column 103 can be inserted into the mounting hole and the nut 104 can be tightened. Of course, the valve seat 100 can also be welded or clamped on the water tank body 500 or the water inlet pipe. The valve seat 100 is provided with a water inlet channel 101. After the valve seat 100 is installed, the water inlet channel 101 can be connected to the water inlet pipe of the water tank, and the water in the water inlet pipe enters the water tank through the water inlet channel 101.

[0054] refer to Figure 3 As shown, the valve core 200 can be movably arranged on the valve seat 100, and the valve core 200 can move in various ways. For example, the valve seat 100 can be provided with a valve cavity 102, and the valve core 200 can be slidably installed in the valve cavity 102, and the valve core 200 can block or open the water inlet channel 101 during the sliding process. In addition, the valve core 200 can also be rotatably installed on the valve seat 100, and the valve core 200 can block or open the water inlet channel 101 during the rotation process.

[0055] refer to Figures 1 to 3As shown, the transmission member 300 is rotatably connected to the valve seat 100. For example, the valve seat 100 may be provided with a mounting shaft 105, and the transmission member 300 is rotatably sleeved on the outer side of the mounting shaft 105. In addition, the valve seat 100 may also be provided with a first connecting hole, and the transmission member 300 is provided with a mounting shaft 105 and is rotatably installed in the first connecting hole through the mounting shaft 105. The transmission member 300 can drive the valve core 200 to move during rotation. Specifically, when the transmission member 300 drives the valve core 200 to move in a direction away from the water inlet channel 101, the valve core 200 opens the water inlet channel 101, and when the transmission member 300 drives the valve core 200 to move in a direction close to the water inlet channel 101, the valve core 200 blocks the water inlet channel 101. After the valve seat 100 is installed in the water tank, the rotation axis between the transmission member 300 and the valve seat 100 can extend in the horizontal direction.

[0056] refer to Figure 1 and Figure 2 As shown, the floating part 400 is rotatably connected to the transmission member 300. After the valve seat 100 is installed in the water tank, the floating part 400 is located in the water tank body 500, and the rotation axis between the floating part 400 and the transmission member 300 can extend in the horizontal direction. The floating part 400 is configured to float on the water surface in the water tank and float up and down following the change of the water level.

[0057] When the floating part 400 floats upward or downward under the buoyancy of water, it can drive the transmission member 300 to rotate relative to the valve seat 100, and when the transmission member 300 rotates relative to the valve seat 100, the transmission member 300 will rotate relative to the floating part 400, and the floating part 400 will not flip over with the transmission member 300.

[0058] In the present invention, when the water level in the water tank drops, the floating part 400 floats down and drives the transmission part 300 to rotate, and the transmission part 300 further drives the valve core 200 to move to open the water inlet channel 101, thereby realizing water inlet to the water tank. When the water level in the water tank rises to a preset position, the floating part 400 floats up and drives the transmission part 300 to rotate, and the transmission part 300 further drives the valve core 200 to move to block the water inlet channel 101, thereby realizing water inlet to the water tank is stopped.

[0059] Since the floating part 400 is rotatably connected to the transmission member 300, when the floating part 400 floats up and drives the transmission member 300 to rotate relative to the valve seat 100, the transmission member 300 will also rotate relative to the floating part 400, and the floating part 400 itself will not flip over with the transmission member 300, thereby preventing the end of the floating part 400 away from the transmission member 300 from tilting upward and touching the top plate of the water tank, thereby increasing the floating height of the floating part 400, thereby increasing the floating stroke of the floating part 400, improving the utilization rate of the water tank, and being able to store more water.

[0060] refer to Figure 1 As shown, in some embodiments of the present invention, the rotation axis between the floating part 400 and the transmission member 300 is parallel to the rotation axis between the transmission member 300 and the valve seat 100. For example, after the valve seat 100 is installed in the water tank, the rotation axis between the floating part 400 and the transmission member 300 can extend in the horizontal direction, the rotation axis between the transmission member 300 and the valve seat 100 can extend in the horizontal direction, and the rotation axis between the floating part 400 and the transmission member 300 is parallel to the rotation axis between the transmission member 300 and the valve seat 100.

[0061] In this embodiment, when the floating part 400 floats up and down following the change of water level, not only the transmission member 300 rotates more smoothly relative to the valve seat 100, but also the transmission member 300 rotates more smoothly relative to the floating part 400, thereby avoiding interference and jamming.

[0062] It should be noted that in some other embodiments of the present invention, the rotation axis between the floating portion 400 and the transmission member 300 and the rotation axis between the transmission member 300 and the valve seat 100 may also form a slight angle, for example, an angle of 1° or 2°, which will not be repeated here.

[0063] refer to Figure 1 As shown, in some embodiments of the present invention, the floating part 400 is set to be flat, and the rotation axis between the floating part 400 and the transmission member 300 is perpendicular to the thickness direction of the floating part 400. For example, the floating part 400 can be roughly a flat rectangular structure, and the rotation axis between the floating part 400 and the transmission member 300 can be parallel to the width direction of the floating part 400. Such a configuration can make the lower surface of the floating part 400 in the thickness direction float on the water surface, thereby not only making the floating part 400 float more stably and reducing the situation of the floating part 400 turning over, but also the size of the floating part 400 in the vertical direction is smaller, and it is less likely to touch the top plate of the water tank body 500, thereby further improving the floating stroke of the floating part 400, the water tank utilization rate is higher, and more water can be stored, and the practicality is better.

[0064] It should be noted that in some other embodiments of the present invention, the floating portion 400 may also be in other suitable shapes, such as a cylindrical shape, which will not be described in detail herein.

[0065] refer to Figure 4As shown, in a further embodiment of the present invention, the floating part 400 is formed with a floating cavity 401, and a reinforcement part 402 is provided in the floating cavity 401, and the two ends of the reinforcement part 402 are respectively connected to the two side walls of the floating part 400 along the thickness direction. That is, the floating part 400 is a hollow structure, which can not only reduce the weight of the floating part 400, so that the floating part 400 has a better floating effect, but also save materials and reduce costs. In addition, the floating part 400 can be blow-molded, which is more convenient to process.

[0066] There can be one or more reinforcing parts 402. When there are multiple reinforcing parts 402, the multiple reinforcing parts 402 can be arranged along the length direction of the floating part 400. The reinforcing parts 402 can play a role in reinforcing the structure. The reinforcing parts 402 can support the two side walls in the thickness direction of the floating part 400 to prevent the two side walls in the thickness direction of the floating part 400 from being deformed or even broken due to excessive water pressure, thereby making the floating part 400 less prone to damage and having a longer service life.

[0067] refer to Figure 1 , Figure 2 and Figure 4 As shown, further, cavities 403 are formed at both ends of the reinforcing portion 402, and the two cavities 403 respectively penetrate the two side walls of the floating portion 400 along the thickness direction. The reinforcing portion 402 is formed with cavities 403, which can not only further reduce the weight of the floating portion 400, so that the floating effect of the floating portion 400 is better, but also can further save materials and reduce costs. In addition, the reinforcing portion 402 can also be blow-molded, which is more convenient to process.

[0068] refer to Figure 4 As shown, further, the outer diameter of the reinforcing portion 402 gradually decreases from the two ends to the middle of the reinforcing portion 402. That is, the outer contour of the reinforcing portion 402 is in an hourglass shape as a whole, so that while ensuring the connection strength between the reinforcing portion 402 and the two side walls of the floating portion 400 in the thickness direction, it can also further save materials and reduce costs.

[0069] refer to Figure 1 and Figure 2As shown, in some embodiments of the present invention, the end of the transmission member 300 away from the valve seat 100 is provided with two mounting parts 307, and the two mounting parts 307 are respectively rotatably connected to the two sides of the middle position in the length direction of the floating part 400. For example, the mounting part 307 may be provided with a second connection hole, and the two opposite sides of the floating part 400 are respectively provided with a connection shaft 404, or the mounting part 307 may be provided with a connection shaft 404, and the two opposite sides of the floating part 400 are respectively provided with a second connection hole, and the two connection shafts 404 are respectively rotatably installed in the two second connection holes. In this way, when the floating part 400 floats on the water surface, not only can the floating stability of the floating part 400 be further improved, and the situation of the floating part 400 turning over can be further reduced, but even if the floating part 400 turns over, the height of the end of the floating part 400 away from the transmission member 300 that tilts upward is small, and will not touch the top plate of the water tank, which is more practical.

[0070] It is understandable that in some other embodiments of the present invention, the two mounting portions 307 may also be rotatably connected to the two sides of the middle position of the floating portion 400 in the width direction. Such an arrangement also has the above-mentioned beneficial effects, which will not be repeated here.

[0071] refer to Figure 1 , Figure 2 and Figure 4 As shown, in a further embodiment of the present invention, the reinforcing portion 402 includes a plurality of reinforcing portions 402, and the plurality of reinforcing portions 402 are arranged along the length direction of the floating portion 400, and at least one reinforcing portion 402 is located between the connection positions of the two mounting portions 307 and the floating portion 400. For example, three reinforcing portions 402 may be provided, one of which is located between the connection positions of the two mounting portions 307 and the floating portion 400, and the other two reinforcing portions 402 may be symmetrically arranged relative to the rotation axis of the floating portion 400.

[0072] In this embodiment, multiple reinforcement parts 402 are provided, so that the floating part 400 has a higher structural strength, is less prone to damage, and has a longer service life. Moreover, at least one reinforcement part 402 is located between the connection positions of the two mounting parts 307 and the floating part 400, which not only makes the structural strength of the connection position of the mounting part 307 and the floating part 400 higher and the connection more stable, but also can avoid the deformation of the position where the floating part 400 is connected to the mounting part 307, which causes the mounting part 307 to rotate unevenly relative to the floating part 400.

[0073] It should be noted that when the two mounting parts 307 are respectively rotationally connected to the two sides of the middle position in the length direction of the floating part 400, there may be a reinforcing part 402 located between the connection positions of the two mounting parts 307 and the floating part 400; and when the two mounting parts 307 are respectively rotationally connected to the two sides of the middle position in the width direction of the floating part 400, there may be multiple reinforcing parts 402 located between the connection positions of the two mounting parts 307 and the floating part 400.

[0074] refer to Figures 1 to 3 As shown, in some embodiments of the present invention, the transmission member 300 includes a driving part 301 and a connecting part 302. The driving part 301 is rotatably connected to the valve seat 100. The driving part 301 can drive the valve core 200 to move during rotation. The connecting part 302 is connected to the driving part 301 and can be rotated and adjusted around a first axis. The first axis is parallel to the rotation axis of the driving part 301. The floating part 400 is rotatably connected to one end of the connecting part 302 away from the driving part 301. The floating part 400 drives the driving part 301 to rotate through the connecting part 302.

[0075] In this embodiment, the connecting part 302 can be rotated and adjusted around the first axis, that is, the connecting part 302 can be fixed on the driving part 301 after being rotated and adjusted to a set angle around the first axis. In this way, the angle required for the transmission member 300 to drive the valve core 200 to rotate from fully opening the water inlet channel 101 to blocking the water inlet channel 101 can be adjusted, and then the floating stroke of the floating part 400 can be adjusted, so that water can be supplied when the water level in the water tank drops to different heights, and water supply can be stopped when the water level in the water tank rises to different heights, so that the water control volume of the water tank can be adjusted according to actual needs.

[0076] It can be understood that the first axis may coincide with the rotation axis of the driving portion 301 , or there may be a gap between the first axis and the rotation axis of the driving portion 301 , as long as the two are parallel.

[0077] refer to Figure 2 and Figure 3 As shown, in some embodiments of the utility model, the connecting part 302 is detachably connected to the driving part 301, the driving part 301 is provided with a plurality of first teeth 303, the connecting part 302 is provided with a plurality of second teeth 304, the plurality of first teeth 303 and the plurality of second teeth 304 are staggered along the circumferential direction of the first axis, and the first tooth 303 can be inserted between any two adjacent second teeth 304.

[0078] For example, the driving part 301 can be provided with a first matching part 305, the first matching part 305 forms a first matching surface, and multiple first teeth 303 are arranged on the first matching surface. The connecting part 302 can be provided with a second matching part 306, the second matching part 306 forms a second matching surface, and multiple second teeth 304 are arranged on the second matching surface. The first matching part 305 and the second matching part 306 are both provided with through holes, the first matching surface is attached to the second matching surface, the two through holes are aligned and fasteners such as screws are installed, the multiple first teeth 303 and the multiple second teeth 304 are staggered along the circumferential direction of the first axis, the first tooth 303 is inserted between two adjacent second teeth 304, and the second tooth 304 is inserted between two adjacent first teeth 303.

[0079] When the connection part 302 needs to be rotationally adjusted, the fastener is removed, and then the first tooth 303 is inserted between the other two adjacent second teeth 304, and finally the fastener is reinstalled in the two through holes. The structure is simple, the operation is convenient, time-saving and labor-saving, and the angle adjustment is more precise.

[0080] It should be noted that the connection part 302 and the driving part 301 can also be snap-fitted. In addition, one of the connection part 302 and the driving part 301 can be provided with an outer gear ring, and the other can be provided with an inner gear ring, the outer gear ring and the inner gear ring are meshed with each other, one of the teeth of the outer gear ring and the teeth of the inner gear ring forms the first teeth 303, and the other forms the second teeth 304. In addition, the transmission member 300 can also be rotationally adjusted in other ways. For example, a plurality of third connection holes can be provided in the driving part 301, and the plurality of third connection holes are arranged along the circumference of the first axis. The transmission member 300 is correspondingly provided with a plurality of fourth connection holes, and the plurality of fourth connection holes are arranged along the circumference of the first axis. The fourth connection holes are aligned with different third connection holes and fasteners are inserted, and the connection part 302 can also be rotationally adjusted.

[0081] refer to Figure 3 As shown, in some embodiments of the present invention, the valve core 200 has two abutting surfaces 201, the two abutting surfaces 201 are arranged along the moving direction of the valve core 200, the transmission member 300 extends between the two abutting surfaces 201, and the transmission member 300 can rotate to respectively abut the two abutting surfaces 201 to push the valve core 200 to move. For example, the valve core 200 can be provided with a matching groove 202, the two inner walls of the matching groove 202 along the moving direction of the valve core 200 form the abutting surfaces 201, the transmission member 300 extends into the matching groove 202, and along the moving direction of the valve core 200, the distance between the two abutting surfaces 201 is greater than the size of the portion of the transmission member 300 located in the matching surface.

[0082] When the transmission member 300 rotates to abut the abutting surface 201 of the valve core 200 close to the water inlet channel 101 and continues to rotate, the transmission member 300 can push the valve core 200 to move and block the water inlet channel 101. When the transmission member 300 rotates in the opposite direction to abut the abutting surface 201 of the valve core 200 away from the water inlet channel 101 and continues to rotate, the transmission member 300 can push the valve core 200 to move and open the water inlet channel 101. The structure is simple and the driving is convenient. In addition, after the transmission member 300 abuts against one of the abutting surfaces 201, it needs to rotate a certain angle to abut against the other abutting surface 201. Then, when the water level rises and falls and the transmission member 300 rotates, the water inlet channel 101 will not be immediately blocked or opened, but the water level will drop or rise a certain distance before water can enter or stop entering, thereby avoiding the float valve from being damaged due to excessive movement.

[0083] It should be noted that the transmission member 300 may also drive the valve core 200 to move in other ways, for example, it may be hinged to the valve core 200 .
