Description

Technical Field

[0001] This invention relates to the field of humidification air outlet equipment technology, specifically to a water tank device and a humidification air outlet equipment. Background Technology

[0002] Humidifying air outlet devices such as air coolers use an evaporative cooling structure that cools the air by evaporating water. The working principle is that a water pump draws water from a water tank and delivers it to the evaporator. The water is evenly distributed over a large area on the evaporator. The water on the evaporator evaporates and absorbs heat. The heat of the air blowing over the evaporator is absorbed, making the air blown out by the air cooler cooler at a lower temperature.

[0003] In related technologies, water tanks typically have a water inlet with a detachable water cap. Adding water usually requires manually removing the cap and then manually reinstalling it. However, the cap is small, making removal and installation inconvenient. Furthermore, different installation methods by different people can lead to misalignment, potentially causing leaks in the water tank. Summary of the Invention

[0004] In view of this, the present invention provides a water tank device and a humidifying air outlet device to solve the problem of inconvenience caused by the need to remove the water filling cap when adding water to the water tank device.

[0005] In a first aspect, the present invention provides a water tank device, comprising:

[0006] The enclosure has a connecting port;

[0007] The water valve is sealed to the connecting port.

[0008] The first force-generating component is connected to the housing and is adapted to apply a first force to the valve core of the water valve.

[0009] The second force-generating component is connected to the water valve and is adapted to apply a second force to the valve core of the water valve.

[0010] When the first force is greater than the second force, the water valve opens; when the first force is less than the second force, the water valve closes.

[0011] Beneficial effects: The enclosure is equipped with a connecting port and a water valve. The opening and closing of the water valve are controlled by a first force-operating component and a second force-operating component. When the first force of the first force-operating component is greater than the second force of the second force-operating component, the water valve opens, allowing water to be added to the enclosure without disassembling the valve. This simplifies the water adding process and reduces the risk of leakage caused by disassembly and installation errors. When the first force of the first force-operating component is less than the second force of the second force of the second force-operating component, the water valve closes, keeping the enclosure sealed and preventing leakage.

[0012] In one optional embodiment, the first force-generating component includes:

[0013] A buoyancy component is movably disposed within the box and located below the communication opening;

[0014] The pusher has one end connected to the buoyancy member and the other end adapted to apply a first force to the valve core of the water valve.

[0015] Beneficial effects: The buoyancy component rises or falls according to the liquid level in the tank. When the liquid level is below the preset level, the weight of the buoyancy component is greater than the buoyancy, and the buoyancy component exerts a pushing force on the pusher. This pushing force is the first force. When the first force is greater than the second force, the water valve can be opened by the pusher. When the liquid level reaches or approaches the preset level, the weight of the buoyancy component is less than the buoyancy, and the buoyancy component rises. It no longer exerts a pushing force on the pusher or the pushing force decreases. The first force is less than the second force, and the water valve can be closed under the action of the second force. Furthermore, because the buoyancy component is located below the connecting port, the preset liquid level is lower than the connecting port. Once the tank reaches the preset liquid level, the water valve closes, preventing further water addition and ensuring that the tank does not overflow through the connecting port.

[0016] In one optional embodiment, the communication port is located at the top of the side wall of the box; the buoyancy component includes a float and a transmission rod, the transmission rod being rotatably connected to the box, one end of which is connected to the float and the other end of which is connected to the pusher.

[0017] Beneficial effects: Due to the transmission rod, the vertical movement of the float can be transmitted and converted into horizontal movement, facilitating the control of the water valve's opening and closing. Furthermore, because the connection port is located on the top side wall of the tank, leakage at the connection port is prevented.

[0018] In one alternative embodiment, the water tank assembly further includes a tank cover, the tank cover comprising:

[0019] A cover, which is placed on top of the box body;

[0020] The first bracket is fixedly connected to the cover, and the transmission rod is rotatably connected to the end of the first bracket away from the cover;

[0021] The second bracket is fixedly connected to the cover and spaced between the first bracket and the communication port. The pusher is slidably connected to the second bracket.

[0022] The cover is placed on top of the tank, protecting it and providing good support. The first bracket facilitates the connection of the transmission rod. The second bracket facilitates the limiting connection of the pushing component. The cover, the first bracket, and the second bracket can limit the connection of the buoyancy component and the pushing component on the top of the tank, and facilitates cooperation with the water valve.

[0023] In one optional embodiment, the transmission rod includes a first rod body and a second rod body, one end of the first rod body and one end of the second rod body are connected at an acute angle, and the connection is rotatably connected to the first bracket; the other end of the first rod body is connected to the float plate, and the other end of the second rod body is connected to the transmission plate, and the transmission plate is in movable contact with the pusher.

[0024] In one alternative embodiment, the cover is detachably attached to the housing. This detachable attachment allows for easy removal to clean and maintain the interior of the housing.

[0025] In one alternative embodiment, the second bracket is provided with a first sliding hole, and the pusher slides through the first sliding hole.

[0026] Beneficial effects: The first sliding hole can limit and guide the pusher, preventing it from tilting or falling, and can also guide its movement.

[0027] In one optional embodiment, the pushing member is provided with a second sliding hole, the second sliding hole is a strip-shaped hole, and the length direction of the second sliding hole is consistent with the depth direction of the first sliding hole; the first force-generating member further includes a limiting shaft, the limiting shaft is slidably inserted through the second sliding hole, and its two ends are respectively connected to the hole wall of the first sliding hole.

[0028] Beneficial effects: The second sliding hole further limits the movement of the pusher. Furthermore, the second sliding hole can limit the range of movement of the pusher; when the limiting shaft moves to either end of the length direction of the second sliding hole, the pusher stops moving.

[0029] In one alternative embodiment, the water valve includes:

[0030] A valve body is sealed to the communication port, and a valve cavity is provided on the valve body;

[0031] The valve core is movably disposed within the valve cavity; it has a first open position for opening the valve cavity and a first closed position for closing the valve cavity;

[0032] The second force-generating component is connected between the valve core and the valve body; it is adapted to apply the second force to the valve core, and the first force-generating component is adapted to apply the first force to the valve core.

[0033] Beneficial effects: The valve core can cooperate with the first force-generating component. When the first force of the first force-generating component is greater than the second force of the second force-generating component, the valve core moves to the first open position to open the tank and allow water to be added. When the first force of the first force-generating component is less than the second force of the second force of the second force-generating component, the valve core closes under the action of the second force of the second force of the second force-generating component, and the tank will not leak water.

[0034] In one alternative embodiment, the valve core includes:

[0035] The valve stem has one end that engages with the first force-generating component, and the outer periphery of the other end is provided with a limiting flange; the valve stem is movably disposed within the valve cavity;

[0036] The piston is fixedly connected to the other end of the valve stem and has a first closed position and a first open position.

[0037] The second force-generating component is a spring, which is sleeved on the outer periphery of the valve stem, with one end connected to the limiting flange and the other end connected to the valve cavity.

[0038] In one optional embodiment, the valve chamber is provided with a fluid inlet and a fluid outlet. The fluid inlet is connected to the first housing. When the water valve is sealed to the second communication port, the fluid outlet is connected to the second housing. The piston is adapted to close or open the fluid inlet.

[0039] In one optional embodiment, the water valve further includes an elastic cover, which is sealed at one end of the valve body and disposed between the first force-generating member and the valve core.

[0040] In one optional embodiment, the housing includes a first housing and a second housing that are detachably connected, and the communication port includes a first communication port and a second communication port. The first housing is provided with a first communication port, and the second housing is provided with a corresponding second communication port. The water valve is sealed and connected at the first communication port and is detachably sealed and connected to the second communication port.

[0041] Beneficial effects: The first tank can be easily disassembled for water filling, while the second tank can be fixedly installed and connected to the water pump, water pipes, and pump wiring. Therefore, the first tank has a simpler, more compact structure and is lighter, significantly reducing the difficulty of water filling. Furthermore, due to the water valve, when the first and second tanks are separated, the first force-generating component no longer applies the first force; the first force is zero. Since the first force is less than the second force, the water valve closes, preventing leakage from the first tank. After the first and second tanks are connected, the first force-generating component applies the first force to the valve core according to the water demand of the second tank. When the first force is greater than the second force, the water valve opens, and water from the first tank enters the second tank through the first and second connecting ports under gravity. This allows the first tank to be convenient for water filling, water storage, and water supply to the second tank.

[0042] In one optional embodiment, the first box is located above the second box, the first communication port is located at the bottom of the first box, and the second communication port is located at the top of the second box.

[0043] In one alternative embodiment, the water tank device further includes a docking switch adapted to limit the connection between the first tank and the second tank.

[0044] Beneficial effects: The docking switch can limit and fix the first and second enclosures after they are connected in place, which can both ensure that the first and second enclosures are connected in place and limit and fix the first and second enclosures after they are connected in place.

[0045] In one alternative implementation, the docking switch includes:

[0046] The first chute is provided on the first housing;

[0047] The second slide is provided on the second housing;

[0048] The lever has a second open position that is slidably connected to the first slide groove, and a second closed position that is slidably connected to the first slide groove and the second slide groove.

[0049] Beneficial effects: The lever is slidably mounted on the first slide groove. After the first and second housings are connected in place, the lever can move from the first slide groove to the second slide groove to connect with both simultaneously. When the first and second housings are not connected in place, the lever cannot move from the first slide groove to the second slide groove. When it is necessary to disassemble the first housing for water addition, the lever can be moved away from the second slide groove. After the lever is moved into the first slide groove, the docking switch is in the second open position, and the first housing can be removed. Since the first housing is located above the second housing, and the first slide groove is located above the second slide groove, after connection, the lever moves to the second closed position under gravity, or moves to the second closed position under user operation, and can remain in the second closed position under gravity.

[0050] In one alternative embodiment, the top of the side wall of the first housing is provided with a pull-out recess for easy application of force.

[0051] Beneficial effects: Users can apply a horizontal pulling force through the pull-out recess to easily pull out, disassemble, and install the first compartment. They can also apply a vertical or upward-sloping force through the pull-out recess to easily lift the first compartment to the water filling position, or from the water filling position to the location of the second compartment.

[0052] Secondly, the present invention also provides a humidifying air outlet device, including a body and the aforementioned water tank device, wherein the first housing is detachably connected to the body.

[0053] Beneficial effects: The first box is detachably connected to the main body, and the first box does not need to be connected to the water pump, water pipe and water pump wiring, etc. Therefore, the structure of the first box is simpler and more compact, and the weight is lighter, which greatly reduces the difficulty of adding water.

[0054] In one optional implementation, the humidifying air outlet device further includes:

[0055] The base is fixedly connected to the bottom of the machine body, and the second tank body located at the bottom of the water tank device is fixedly connected to the base;

[0056] A water pump is connected to the base, and the water inlet of the water pump is connected to the second housing located at the bottom.

[0057] Beneficial effect: The water pump is located outside the water tank unit, which prevents users from seeing the water pipes, water pump and water pump wiring when cleaning the second tank, making it easier to clean the second tank. Attached Figure Description

[0074] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0075] The following is combined with Figures 1 to 13 The following describes embodiments of the present invention.

[0076] According to an embodiment of the present invention, in one aspect, a water tank device is provided, including a tank body, a water valve 3, a first force-generating component 4, and a second force-generating component 5. The tank body is provided with a communication port, and the water valve is sealed to the communication port. The first force-generating component 4 is connected to the tank body and is adapted to apply a first force to the valve core 33 of the water valve 3. The second force-generating component 5 is connected to the water valve 3 and is adapted to apply a second force to the valve core 33 of the water valve 3. Wherein, when the first force is greater than the second force, the water valve 3 is opened; when the first force is less than the second force, the water valve 3 is closed.

[0077] The enclosure is equipped with a connecting port, at which a water valve 3 is located. The opening and closing of the water valve 3 are controlled by a first force-operating component 4 and a second force-operating component 5. When the first force of the first force-operating component 4 is greater than the second force of the second force-operating component 5, the water valve 3 opens, allowing water to be added to the enclosure without disassembling it. This simplifies the water-adding process and reduces the risk of leakage due to disassembly and installation errors. When the first force of the first force-operating component 4 is less than the second force of ...

[0078] In related technologies, the water tank and the air cooler are fixedly connected. When adding water to the tank, the air cooler needs to be moved to the water source and water is added via a pipe, or a basin or bucket is used to move water between the water source and the air cooler, causing considerable inconvenience to the user. Therefore, to facilitate water addition, some air coolers provide a water tank that is detachably pulled out of the air cooler. When water needs to be added, the water tank is simply pulled out and taken to the water source. However, this type of water tank easily accumulates dirt, is large in size, and heavy, making water addition inconvenient. Furthermore, to facilitate the detachable pull-out connection between the water tank and the air cooler, the water tank usually contains a water pump, water pipes, and water pump connecting wires, which leads to dirt accumulation inside the tank, and the large size and weight of the tank further complicate water addition. In this embodiment,

[0079] In one embodiment, the housing includes a first housing 1 and a second housing 2, and the communication port includes a first communication port and a second communication port 21. The first housing 1 is provided with a first communication port, and the second housing 2 is provided with a corresponding second communication port 21. The water valve 3 is sealed and connected at the first communication port, and is detachably sealed and connected to the second communication port 21.

[0080] Multiple tanks are provided. The first tank 1 can be easily disassembled for water addition, while the second tank 2 can be fixedly installed and connected to the water pump 8, water pipes, and water pump 8 wiring. Therefore, the structure of the first tank 1 is simpler, more compact, and lighter, greatly reducing the difficulty of adding water. Furthermore, due to the water valve 3, when the first tank 1 and the second tank 2 are separated, the first force-generating component 4 no longer applies the first force; the first force is zero, and since the first force is less than the second force, the water valve 3 closes, isolating the first and second connecting ports 21 to prevent leakage from the first tank 1. Because the second connecting port 21 is located at the top of the second tank 2, the second tank 2 also does not leak. After the first tank 1 and the second tank 2 are connected, the first force-generating component 4 applies the first force to the valve core 33 according to the water demand of the second tank 2. When the first force is greater than the second force, the water valve 3 opens, connecting the first and second connecting ports 21. Water in the first tank 1 can enter the second tank 2 through the first connecting port and the second connecting port 21 under gravity, making it convenient for the first tank 1 to add water, store water, and supply water to the second tank 2. Alternatively, water in the first tank 1 can also enter the second tank 2 under the action of a pump.

[0081] In one embodiment, the first housing 1 is located above the second housing 2, the first communication port is located at the bottom of the first housing 1, and the second communication port 21 is located at the top of the second housing 2.

[0082] The first housing is detachably connected vertically to the top of the second housing. When the first and second connecting ports 21 are connected, water in the first housing 1 can automatically enter the second housing 2 under gravity, easily supplying water to the second housing 2 without the need for an additional water pump 8 or other structures, resulting in a relatively simple structure. Furthermore, since the second connecting port 21 is located at the top of the second housing, it will not leak after the first housing is disassembled.

[0083] In a specific implementation, there may be two or more boxes. The box at the bottom can be a fixed box, and the other boxes can be detachably connected to the adjacent box below it. Each pair of adjacent boxes is equipped with a water valve 3, a first force-generating component 4, and a second force-generating component 5.

[0084] Under normal conditions, water valve 3 is normally closed under the action of the second force exertion component 5. Water valve 3 is sealed to the first housing 1, sealing the first connection port of the first housing 1. It will only open and connect the first connection port when the first force exerted on the valve core 33 of water valve 3 is greater than the second force. After the first housing 1 and the second housing 2 are installed in place, water valve 3 is sealed to the second connection port 21. If the water level in the second housing 2 does not reach the preset water level, the first force exertion component 4 applies the first force to the valve core 33 of water valve 3 to connect the first housing 1 and the second housing 2. If the water level in the second housing 2 reaches or is close to the preset water level, the first force exerted by the first force exertion component 4 is zero or less than the second force, and water valve 3 is closed and remains normally closed. When the first housing 1 and the second housing 2 are separated, the closed water valve 3 keeps the first housing 1 sealed, preventing water leakage.

[0085] In one embodiment, the water valve 3 includes a valve body 31 and a valve core 33. The valve body 31 is sealed to the communication port. In this embodiment, the valve body is sealed to the first communication port and detachably sealed to the second communication port 21. The valve body 31 is provided with a valve cavity 32. When the water valve 3 is sealed to the second communication port 21, the valve cavity 32 communicates with the first housing 1 and the second housing 2. The valve core 33 is movably disposed in the valve cavity 32. It has a first open position for opening the valve cavity 32 and a first closed position for closing the valve cavity 32. The second force-applying member 5 is connected between the valve core 33 and the valve body 31. It is adapted to apply a second force to the valve core 33, and the first force-applying member 4 is adapted to apply a first force to the valve core 33.

[0086] The valve core 33 can cooperate with the first force-generating component 4. When the first force of the first force-generating component 4 is greater than the second force of the second force-generating component 5, the valve core 33 moves to the first open position to connect the first housing 1 and the second housing 2. Water in the first housing 1 automatically enters the second housing 2 under the action of gravity. When the first force of the first force-generating component 4 is less than the second force of the second force of the second force-generating component 5, the valve core 33 closes under the action of the second force of the second force-generating component 5, and the first housing 1 and the second housing 2 are mutually isolated, preventing water leakage.

[0087] In one embodiment, the valve core 33 includes a valve stem 331 and a piston 332. One end of the valve stem 331 is engaged with the first force-generating member 4, and a limiting flange is provided on the outer periphery of one end of the valve stem 331. The valve stem 331 is movably disposed in the valve cavity 32. The piston 332 is fixedly connected to the other end of the valve stem 331 and has a first closed position and a first open position. The second force-generating member 5 is a spring, which is sleeved on the outer periphery of the valve stem 331, with one end connected to the limiting flange and the other end connected to the valve cavity 32.

[0088] When the first force acting on valve stem 331 is greater than the second force, the second force-generating component 5 is compressed and moved. Valve stem 331 drives piston 332 from the first closed position to the first open position, and water valve 3 opens. When the first force acting on valve stem 331 is less than the second force, valve stem 331 drives piston 332 from the first open position to the first closed position, and water valve 3 closes.

[0089] Specifically, a support portion protrudes from the inner wall of the valve cavity 32, and a sliding hole is provided on the support portion. The valve stem 331 slides through the sliding hole. The second force-generating member 5 is sleeved on the outer periphery of the valve stem 331, and both ends of the second force-generating member 5 abut against the limiting flange and the support portion, respectively.

[0090] In one embodiment, the valve chamber 32 is provided with a fluid inlet 321 and a fluid outlet 322. The fluid inlet 321 communicates with the housing. Taking the fluid inlet communicating with the first housing 1 as an example, when the water valve 3 is sealed to the second communication port 21, the fluid outlet 322 communicates with the second housing 2. The piston 332 is adapted to close or open the fluid inlet 321. When the piston 332 is in the first open position, the piston 332 moves away from the fluid inlet 321 and opens it; when the piston 332 is in the second open position, the piston 332 blocks the fluid inlet 321 and closes it. Alternatively, the piston 332 can also be used to open or close the fluid outlet 322.

[0091] In a specific embodiment, the fluid inlet 321 is located at one axial end of the water valve 3; the fluid outlet 322 is located at the other axial end of the water valve 3, and is positioned below it. A water-dividing structure is provided on the valve core 33 at one end of the fluid inlet 321. The water-dividing structure includes a conical water-dividing platform and reinforcing ribs connected to the outer periphery of the conical water-dividing platform. The water valve 3 can be integrally molded onto the first housing 1 via secondary injection molding, or it can be detachably fixed to the first housing 1 via a snap-fit ​​or other structure. The outer diameter of the water valve 3 is smaller than the diameter of the second connecting port 21 to facilitate a detachable connection between the water valve 3 and the second housing 2.

[0092] In one embodiment, the water valve 3 further includes an elastic cover 34, which is sealed at one end of the valve body 31. For example, the elastic cover 34 is positioned at the end of the valve body 31 furthest from the first housing 1. The elastic cover 34 is located between the first force-applying member 4 and the valve core 33. The elastic cover 34 can both seal the end of the water valve 3 and facilitate the first force-applying member 4 to apply a first force to the valve core 33.

[0093] In one embodiment, the first force-generating component 4 includes a buoyancy component 41 and a pusher component 42; the buoyancy component 41 is movably disposed in the housing, and is described here as disposed in the second housing 2, and is located below the second communication port 21; one end of the pusher component 42 is connected to the buoyancy component 41, and the other end applies a first force to the valve core 33 of the water valve 3.

[0094] The buoyancy component 41 can rise or fall according to the liquid level in the second tank 2. When the liquid level has not reached the preset level, the weight of the buoyancy component 41 is greater than the buoyancy, and the buoyancy component 41 applies a pushing force to the pusher 42. This pushing force is the first force. When the first force is greater than the second force, the water valve 3 can be opened by the pusher 42. When the liquid level reaches or is close to the preset level, the weight of the buoyancy component 41 is less than the buoyancy, and the buoyancy component 41 rises. It no longer applies a pushing force to the pusher 42 or the pushing force decreases, and the first force is less than the second force. The water valve 3 can be closed under the action of the second force. Furthermore, since the buoyancy component 41 is located below the second connecting port 21, the preset liquid level is lower than the second connecting port 21. After the second tank 2 reaches the preset liquid level, the water valve 3 closes, and the first tank 1 will no longer add water to the second tank 2, ensuring that the second tank 2 will not overflow through the second connecting port 21.

[0095] As an alternative implementation, the first force-generating component 4 may include an electric push rod and a liquid level sensor. The liquid level sensor is used to detect the liquid level in the second tank 2, and the electric push rod opens or closes the water valve 3 according to the liquid level detected by the liquid level sensor.

[0096] In one embodiment, the communication port is located at the top of the side wall of the box; the buoyancy member 41 includes a float plate 411 and a transmission rod 412, the transmission rod 412 is rotatably connected to the box, one end is connected to the float plate 411, and the other end is connected to the pusher 42.

[0097] Thanks to the transmission rod 412, the up-and-down movement of the float 411 can be transmitted and converted into horizontal movement, facilitating the control of the water valve 3. Furthermore, because the connection port is located at the top of the side wall of the tank, water leakage is prevented at the connection port.

[0098] Specifically, the second communication port 21 is located on the side wall of the second housing 2; the buoyancy component 41 includes a float plate 411 and a transmission rod 412, the transmission rod 412 is rotatably connected inside the second housing 2, one end is connected to the float plate 411 and the other end is connected to the pusher 42.

[0099] Due to the transmission rod 412, the up-and-down movement of the float 411 can be transmitted and converted into horizontal movement, facilitating the control of the water valve 3. Furthermore, when the first housing 1 and the second housing 2 are separated, the second connecting port 21, located on the side wall of the top of the second housing 2, prevents water leakage at the second connecting port 21.

[0100] Specifically, when the liquid level in the second tank 2 has not reached the preset level, the float 411 descends under gravity, causing the transmission rod 412 to rotate in the forward direction. The end of the transmission rod 412 away from the float 411 moves toward the direction of the second connection port 21 and applies a pushing force to the pusher 42. The pusher 42 then applies a force to the water valve 3 to open the water valve 3. When the liquid level in the second tank 2 reaches the preset level, the float 411 rises under buoyancy, causing the transmission rod 412 to rotate in the reverse direction. The end of the transmission rod 412 away from the float 411 moves away from the direction of the second connection port 21 and no longer applies a pushing force to the pusher 42. The water valve 3 returns to its normally closed state under the elastic force of its own second force-generating component 5.

[0101] In a specific embodiment, the top of the second housing 2 is provided with a groove on one side. The groove is L-shaped and includes a first groove wall arranged vertically and a second groove wall arranged horizontally. A second connecting port 21 is provided on the first groove wall. The bottom wall of the first housing 1 is provided with a corresponding protrusion, and the protrusion has a first connecting port on its inner side wall near the bottom wall of the first housing 1. The first housing 1 and the second housing 2 can be pulled out horizontally or vertically. In this embodiment, the first housing 1 and the second housing 2 are pulled out horizontally, and the first groove wall and the inner side wall are adapted to abut against each other; the bottom of the protrusion slides in conjunction with the second groove wall.

[0102] In one embodiment, the water tank device further includes a tank cover 6, which includes a cover body 61, a first bracket 62, and a second bracket 63. The cover body 61 covers the top of the second tank body 2. The first bracket 62 is fixedly connected to the cover body 61, and a transmission rod 412 is rotatably connected to the end of the first bracket 62 away from the tank cover 6. The second bracket 63 is fixedly connected to the cover body 61 and is spaced between the first bracket 62 and the second communication port 21. The pusher 42 is slidably connected to the second bracket 63.

[0103] The cover 61 is placed on top of the second housing 2, protecting it and providing good support for the first housing 1. The first bracket 62 facilitates the connection of the transmission rod 412. The second bracket 63 facilitates the limiting connection of the pusher 42. The cover 61, the first bracket 62, and the second bracket 63 limit the connection of the buoyancy member 41 and the pusher 42 to the top of the second housing 2 and facilitate their cooperation with the valve.

[0104] In a specific embodiment, the first support 62 includes a first support rod and a second support rod. The ends of the first support rod and the second support rod away from the cover 61 are provided with a first shaft hole. The transmission rod 412 is provided with a corresponding second shaft hole. The rotating shaft is rotatably inserted through the second shaft hole, and its two ends are respectively connected to the first shaft hole of the first support rod and the first shaft hole of the second support rod.

[0105] In one embodiment, the cover 61 is detachably connected to the housing, specifically, the cover 61 is detachably connected to the second housing 2. The detachable connection of the cover 61 to the second housing 2 facilitates the removal of the cover for cleaning and maintenance of the interior of the second housing 2 and the cover itself.

[0106] In one embodiment, the transmission rod 412 includes a first rod body and a second rod body. One end of the first rod body is connected to one end of the second rod body at an acute angle, and the connection is rotatably connected to the first bracket 62. The other end of the first rod body is connected to the float plate 411, and the other end of the second rod body is connected to the transmission plate 413. The transmission plate 413 is in movable contact with the pusher 42.

[0107] The first and second rods are connected at an acute angle, which can reduce the distance between the float 411 and the pusher 42, allowing the overall structure to be made more compact. This also raises the water level in the second tank 2, allowing it to hold more water. Even if the first tank 1 is removed and water is added, the second tank 2 can still be used. The transmission plate 413 is movably abutted against the pusher 42 and can also be rotatably connected.

[0108] In one embodiment, the second bracket 63 is provided with a first sliding hole 631, and the pusher 42 slides through the first sliding hole 631.

[0109] The first sliding hole 631 can limit and guide the pusher 42, prevent the pusher 42 from tilting and falling, and also guide the movement of the pusher 42.

[0110] In a specific embodiment, the second bracket 63 includes a third support rod, a fourth support rod, and a fifth support rod. The tops of the third and fourth support rods are connected to the cover 61 at intervals. The two ends of the fifth support rod are respectively connected to the bottoms of the third and fourth support rods. The first sliding hole 631 is provided on the fifth support rod.

[0111] In one embodiment, the pusher 42 is provided with a second sliding hole 421, which is a strip-shaped hole, and the length direction of the second sliding hole 421 is consistent with the depth direction of the first sliding hole 631; the first force-generating member 4 also includes a limiting shaft 43, which is slidably disposed in the second sliding hole 421, and its two ends are respectively connected to the hole wall of the first sliding hole 631.

[0112] The second sliding hole 421 further limits the movement of the pusher 42. Furthermore, the second sliding hole 421 also limits the range of movement of the pusher 42; when the limiting shaft 43 moves to either end of the length direction of the second sliding hole 421, the pusher 42 stops moving.

[0113] In a specific embodiment, the top of the pushing member 42 is spaced apart from the top wall of the first sliding hole 631, allowing the pushing member 42 to rotate up and down within a small range in the first sliding hole 631 to accommodate the rotation of the transmission member. The shape of the pushing member 42 matches the shape of the first sliding hole 631. In a preferred embodiment, the pushing member 42 is a square rod-shaped structure, and the cross-section of the first sliding hole 631 is rectangular. The pushing member 42 and the transmission rod 412 can abut against each other or be rotatably connected.

[0114] In one embodiment, the water tank device further includes a docking switch 7, adapted to limit the connection between the first tank 1 and the second tank 2.

[0115] The docking switch 7 can limit and fix the connection between the first housing 1 and the second housing 2 after they are connected in place. It can both detect whether the first housing 1 and the second housing 2 are connected in place, and limit and fix the first housing 1 and the second housing 2 after they are connected. This prevents water overflow or leakage between the first housing 1 and the second housing 2 if they are not connected in place.

[0116] In one embodiment, the docking switch 7 includes a first slide 71, a second slide 72, and a lever 73; the first slide 71 is disposed on the first housing 1; the second slide 72 is disposed on the second housing 2; the lever 73 has a second open position slidably connected to the first slide 71, and a second closed position slidably connected to the first slide 71 and the second slide 72.

[0117] The lever 73 is slidably mounted on the first slide groove 71. After the first housing 1 and the second housing 2 are connected in place, the lever 73 can move from the first slide groove 71 to the second slide groove 72 to connect with both slide grooves simultaneously. When the first housing 1 and the second housing 2 are not connected in place, the lever 73 cannot move from the first slide groove 71 to the second slide groove 72. When it is necessary to disassemble the first housing 1 to add water, the lever 73 can be moved away from the second slide groove 72. After the lever 73 is moved into the first slide groove 71, the docking switch 7 is in the second open position, and the first housing 1 can be removed. Since the first housing 1 is located above the second housing 2, and the first slide groove 71 is located above the second slide groove 72, after connection, the lever 73 moves to the second closed position under gravity, or moves to the second closed position under user operation, and can remain in the second closed position under gravity.

[0118] In a further embodiment, the water tank device also includes a contact switch, which can be used to detect the status of the docking switch 7. If the docking switch 7 is not closed, the contact switch can provide a reminder by flashing a light or making a buzzer.

[0119] In one embodiment, the top of the side wall of the first housing 1 is provided with a pull-out recess 11 for easy application of force. The user can apply a horizontal pulling force through the pull-out recess 11 to facilitate the pulling, disassembly, and installation of the first housing 1. The user can also apply a vertical or upward force through the pull-out recess 11 to facilitate lifting the first housing 1 to the water filling position, or from the water filling position to the position of the second housing 2.

[0120] According to an embodiment of the present invention, another aspect provides a humidifying air outlet device, including a body and the aforementioned water tank device, wherein a first housing 1 is detachably connected to the body.

[0121] The first housing 1 is detachably connected to the main body, and the first housing 1 does not need to be connected to the water pump 8, water pipe and water pump 8 wiring, etc. Therefore, the structure of the first housing 1 is simpler and more compact, and the weight is lighter, which greatly reduces the difficulty of adding water.

[0122] In one embodiment, the humidifying air outlet device further includes a base and a water pump 8; the base is fixedly connected to the bottom of the unit body, and the second tank 2 located at the bottom of the water tank device is fixedly connected to the base; the water pump 8 is connected to the base, and the water inlet 81 of the water pump 8 communicates with the second tank 2 located at the bottom.

[0123] The water pump 8 is located outside the water tank device to prevent users from seeing the water pipes, water pump 8 and water pump 8 wiring when cleaning the second tank 2, thus facilitating the cleaning of the second tank 2.

[0124] In a specific embodiment, the bottom of the second housing 2 is provided with an upwardly recessed L-shaped groove, and the water pump 8 is installed in the L-shaped groove for easy maintenance of the water pump 8. The groove wall of the L-shaped groove is provided with a water outlet 22, and the water inlet 81 of the water pump 8 is connected to the water outlet 22.

[0125] Specifically, humidifying air supply equipment can be water-using equipment such as air coolers and humidifiers.
