Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly relates to a docking device and a cold fan. Background Art

[0002] The cold fan adopts the principle of water evaporation effect and uses physical methods to achieve cooling, solving the problems of excessive "Freon" emissions and high energy consumption of ordinary air conditioners. It usually uses a wet curtain as a cooling medium, and water uniformly flows down along the corrugated surface of the wet curtain from the top, making the wet curtain uniformly wet from top to bottom. When the fan draws air, it generates pressure, forcing unsaturated air to flow through the porous and wet surface of the wet curtain, converting a large amount of heat and humidity in the air into latent heat, forcing the air entering the room to decrease from the dry bulb temperature to approach the wet bulb temperature, increasing the humidity of the air, and turning the dry and hot air into clean and cool air, thus playing the role of cooling and humidifying.

[0003] In the prior art, the cold fan is designed as an integrated water tank and body or a drawer-type water tank. After long-term use, the water tank will have scale and breed bacteria. Since the integrated water tank cannot be disassembled and cleaned, it is inconvenient for users to clean; for the drawer-type water tank, the water pump is hung on the body, and structures such as the water pump flipping are required to make the water tank removable, with complex structures and easy damage during packaging and transportation and other technical problems.

[0004] To solve the problems existing in the above two structures, a split-type cold fan is provided in the prior art, in which the upper body and the lower water tank can be separated from each other. When technicians tested the product, they found that due to the existence of electrical connectors between the water tank and the body, when the water volume in the water tank is too much, the water in the water tank will overflow and splash onto the electrical connectors, causing electric leakage or short circuit. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect of potential electric leakage in the split-type cold fan in the prior art, so as to provide a docking device and a cold fan.

[0006] The present invention provides a docking device, including:

[0007] A first docking structure, including: a first metal coil, the first metal coil being adapted to connect to a first AC wire, and a first insulating housing surrounding the first metal coil;

[0008] A second docking structure, including: a second metal coil, the second metal coil being adapted to connect to a second AC wire, and a second insulating housing surrounding the second metal coil;

[0009] A metal core, adapted to be at least partially disposed in the first metal coil and the second metal coil simultaneously in the working state.

[0010] One of the first insulating housing and the second insulating housing is provided with a recess, and the other of the first insulating housing and the second insulating housing is provided with a protrusion that cooperates with the recess. A metal core is provided inside the protrusion.

[0011] The first insulating housing or the second insulating housing includes a receiving housing and the protrusion provided on the receiving housing. The metal core is provided in the protrusion, and the first metal coil or the second metal coil is provided inside the receiving housing.

[0012] A cold fan includes: a fuselage main body and a water tank assembly that can be detachably arranged;

[0013] At least one set of the above docking devices, one of the first docking structure and the second docking structure of the docking device is provided on the fuselage main body, and the other of the first docking structure and the second docking structure is provided on the water tank assembly.

[0014] The first docking structure is provided on the water tank assembly, and a protrusion is provided on the first insulating housing, and the protrusion is arranged facing the fuselage main body.

[0015] The water tank assembly includes a wave baffle, and the first docking structure is provided on the wave baffle.

[0016] A connection hole is provided on the wave baffle, and the first docking structure is provided on the connection hole.

[0017] A buckle is provided on the fuselage main body, and the second docking structure is provided on the buckle.

[0018] The technical solution of the present invention has the following advantages:

[0019] 1. The present invention provides a docking device, including: a first docking structure, including: a first metal coil adapted to connect a first AC wire, and a first insulating housing surrounding the first metal coil; a second docking structure, including: a second metal coil adapted to connect a second AC wire, and a second insulating housing surrounding the second metal coil; a metal core adapted to be at least partially disposed in the first metal coil and the second metal wire simultaneously in a working state.

[0020] The docking device inserts a metal core into a coil. The metal coil with alternating current flowing through it generates a continuously changing magnetic field in the metal core, causing an alternating current with a changing direction of current to be generated in another metal coil. By using the principle of a transformer and arranging metal coils inside an insulating housing, direct contact between conductive parts is avoided, preventing the occurrence of electric leakage when the docking device is powered on, ensuring electrical safety, achieving wireless transmission of current, and at the same time, the voltage of the wire can also be adjusted, making it more versatile in use.

[0021] 2. For the docking device provided by the present invention, one of the first insulating housing and the second insulating housing is provided with a recess, and the other of the first insulating housing and the second insulating housing is provided with a protrusion that mates with the recess, and a metal core is provided inside the protrusion.

[0022] The first insulating housing and the second insulating housing with the protrusion and recess mating play a role in installation and positioning on the one hand, facilitating the user to connect the first insulating housing and the second insulating housing, and on the other hand, to a certain extent, avoiding the occurrence of tripping and improving the stability of the connection. The metal core provided inside the protrusion avoids the possible contact with the outside world and rust of the metal core when it is arranged outside the insulating housing, which may lead to an increase in eddy current circulation, an increase in the heat generation of the metal core, and excessive local temperature rise, which will affect the insulation of the insulating housing and even burn out the docking device. In addition, the metal core with higher hardness can also ensure the connection strength between the protrusion and the connecting part, preventing external forces from damaging the connection between the first insulating housing and the second insulating housing and improving the stability of the connection.

[0023] 3. For the docking device provided by the present invention, the first insulating housing or the second insulating housing includes a receiving shell and the protrusion provided on the receiving shell, the metal core is provided in the protrusion, and the first metal coil or the second metal coil is provided inside the receiving shell.

[0024] With such an arrangement, the metal core has been pre-placed inside a metal coil and can protrude into another metal coil inside the receiving shell where the recess is located when the docking device is mated, thus realizing the function of wireless conduction. Compared with the arrangement of an external metal core, this arrangement integrates the metal core and a metal coil, making the on-off of the docking device more convenient, preventing the metal core from coming out during operation, and improving the stability of the docking device during operation.

[0025] 4. For the cold fan provided by the present invention, the first docking structure is provided on the water tank assembly, and a protrusion is provided on the first insulating housing, and the protrusion faces the body main body.

[0026] The main body of the body of the cold fan is arranged above the water tank assembly, and the protruding part of the first insulating housing is arranged towards the main body of the body, preventing the water in the water tank from overflowing and splashing onto the concave part when the amount of water in the water tank is too much due to the arrangement of the concave part of the second insulating housing, and accumulating in the concave part. The unevaporated part of the accumulated water will adhere to pollutants after being placed for a long time, thereby causing pollution to the water body in the water tank.

[0027] 5. For the cold fan provided by the present invention, the water tank assembly includes a wave baffle, and the first docking structure is arranged on the wave baffle.

[0028] The wave baffle is arranged at the upper end of the water tank assembly, providing an installation position for the first docking structure. Such an arrangement can, on the one hand, complete the docking of the first docking structure and the second docking structure when the water tank assembly is connected to the main body of the body, simplifying the docking setting of the docking device and facilitating user operation; on the other hand, the wave baffle can reduce the contact between the water overflowing in the water tank and the components at the top of the water tank, and arranging the first docking structure on the wave baffle can reduce the risk of electric leakage caused by the contact between the first alternating current wire in the water tank and water.

[0039] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] Embodiment 1

[0041] As Figure 1 - Figure 4As shown in the figure, this embodiment provides a docking device, including: a first docking structure 1, including: a first metal coil 11 adapted to connect to a first alternating current wire 6, and a first insulating housing 12 surrounding the first metal coil 11; a second docking structure 2, including a second metal coil 21 adapted to connect to a second alternating current wire 7, and a second insulating housing 22 surrounding the second metal coil 21; a metal core 3 adapted to be at least partially disposed in the first metal coil 11 and the second metal coil 21 simultaneously in the working state.

[0042] In this embodiment, the metal core 3 is disposed inside the first insulating housing 12 or the second insulating housing 22. The metal core 3 is an iron core, and the currents in the first alternating current wire 6 and the second alternating current wire 7 are both alternating currents. The working state refers to the state in which alternating current has been passed through one of the docking structures, and the docking device transmits power to the other alternating current wire.

[0043] The docking device inserts the metal core 3 into the coil. The metal coil with alternating current generates a continuously changing magnetic field in the metal core 3, causing an alternating current with a changing direction of current to be generated in the other metal coil. By arranging metal coils inside the insulating housing using the principle of a transformer, direct contact between conductive parts is avoided, so that the docking device will not have a leakage phenomenon due to the contact between conductive parts and the outside during the power-on process, ensuring electrical safety, realizing wireless transmission of current, and at the same time, the voltage of the wire can be adjusted, making it more versatile.

[0044] In this embodiment, a recessed portion is provided in the second insulating housing 22, and the first insulating housing 12 has a protruding portion 121 that cooperates with the recessed portion, and the metal core 3 is disposed inside the protruding portion 121.

[0045] The first insulating housing 12 and the second insulating housing 22 with the protruding and recessed portions cooperatively arranged play a role of installation and positioning on the one hand, facilitating the user to connect the first insulating housing 12 and the second insulating housing 22, and on the other hand, avoiding the occurrence of tripping to a certain extent and improving the connection stability. Disposing the metal core 3 inside the protruding portion 121 avoids the possible contact between the metal core 3 disposed outside the insulating housing and the outside, resulting in rust, an increase in eddy current circulation, an increase in the heat generation of the metal core 3, and too high a local temperature rise, which will affect the insulation of the insulating housing and even burn out the docking device. In addition, the relatively hard metal core 3 can also ensure the connection strength between the protruding portion 121 and the connecting portion, preventing external forces from damaging the connection between the first insulating housing 12 and the second insulating housing 22, and improving the connection stability.

[0046] As a transformable embodiment, the recessed portion can be set as a through hole, and a metal coil is provided on the inner side of the through hole.

[0047] The first insulating housing 12 includes a receiving housing and a protruding portion 121 provided on the receiving housing. The metal core 3 is disposed in the protruding portion 121, and the first metal coil 11 is disposed inside the receiving housing.

[0048] With such an arrangement, the metal core 3 has been pre-placed in a metal coil and can protrude into another metal coil in the receiving housing where the recessed portion is located when the docking device is engaged, thereby realizing the function of wireless conduction. Compared with the arrangement of the external metal core 3, such an arrangement integrates the metal core 3 and a metal coil, making the on-off of the docking device more convenient, preventing the metal core 3 from coming out during operation, and improving the working stability of the docking device.

[0049] This embodiment further provides a cold fan, which includes: a body main body 4 and a water tank assembly 5 that can be detachably arranged; the body main body 4 is disposed above the water tank assembly 5, a power supply 41 is arranged inside the body main body 4, a water pump 51 and a water tank water level induction switch 52 are arranged inside the water tank assembly 5. The cold fan includes two sets of the above-mentioned docking devices. The first AC wire 6 and the second AC wire 7 connected to the metal coil in one set of docking devices are respectively connected to the power supply 41 and the water pump 51, and the AC wires connected to the metal coils on the other set of docking devices are respectively connected to the power supply 41 and the induction switch 52. The two docking devices are arranged in parallel and fixed.

[0050] One of the first docking structure 1 and the second docking structure 2 of the docking device is arranged on the body main body 4, and the other is arranged on the water tank assembly 5. The first docking structure 1 is arranged on the water tank assembly 5, and a protruding portion 121 is provided on the first insulating housing 12, and the protruding portion 121 faces the body main body 4.

[0051] The protruding portion of the first insulating housing 12 faces the body main body 4. Compared with the recessed portion of the second insulating housing 22 arranged in the same way, when the water in the water tank is too much, the water in the water tank overflows and splashes onto the protruding portion, and it will not accumulate on the protruding portion, preventing water accumulation and preventing the unevaporated part from adhering to pollutants after being placed for a long time, thereby avoiding the situation of polluting the water body in the water tank and improving the use safety of the cold fan.

[0052] The water tank assembly 5 further includes a wave baffle 53, and the first docking structure 1 is arranged on the wave baffle 53. The wave baffle 53 is arranged at the upper end of the water tank assembly 5, providing an installation position for the first docking structure 1. Such an arrangement can, on the one hand, complete the docking of the first docking structure 1 and the second docking structure 2 when the water tank assembly 5 is connected to the body main body 4, simplifying the docking setting of the docking device and facilitating user operation; on the other hand, the wave baffle 53 can reduce the contact between the water overflowing in the water tank and the components at the top of the water tank, and arranging the first docking structure 1 on the wave baffle 53 can reduce the risk of electric leakage caused by the first AC wire 6 in the water tank contacting water.

[0053] The wave baffle 53 is provided with connection holes, and the first docking structure 1 is arranged on the connection holes.

[0054] The body main part 4 is provided with a buckle 42, and the second docking structure 2 is arranged on the buckle 42. When the body main part 4 and the water tank assembly 5 are installed and docked, the position of the projection directly below the buckle 42 is the position of the connection hole of the wave baffle 53. At the same time, the distance between the buckle 42 and the connection hole after installation is suitable for the protruding part 121 to enter the recessed part.

[0055] Embodiment 2

[0056] In this embodiment, the setting of the metal core 3 in the above docking device can be changed, and at the same time, the docking device of this embodiment can be commonly used in a cold fan.

[0057] The metal core 3 is arranged on the outer sides of the first insulating housing 12 and the second insulating housing 22. Both the first insulating housing 12 and the second insulating housing 22 are provided with concave parts. The two ends of the metal core 3 are detachably arranged in the concave parts and pass through the first metal coil 11 and the second metal coil 21 arranged on the first insulating housing 12 and the second insulating housing 22.

[0058] Since the magnetic field in the metal core 3 is constantly changing and there is no current passing through, and due to the blocking of the insulating housing, water will not come into contact with the metal coil and will not cause problems such as electric leakage. Therefore, it can overcome the defect of potential electric leakage in the split cold fan in the prior art.

[0059] As a variable implementation manner, the metal core 3 can be in interference connection with the concave part on the first insulating housing 12 or the second insulating housing 22 and be fixed on one of them.

[0060] As a variable implementation manner, the first insulating housing 12 and the second insulating housing 22 may not be provided with concave parts, but instead be replaced with through holes suitable for the metal core 3 to pass through.

[0061] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
