[0002] As people's living standards improve, electrical appliances such as cooling fans are increasingly used in daily life and work environments. These electrical appliances use water pumps to transport water from the water tank to specific components, thereby achieving functions such as cooling and humidification.

[0003] However, there is a common and prominent design flaw in the electrical equipment on the current market. The water pump is mostly installed by immersing it directly inside the water tank. For those electrical equipment that adopts a non-integrated design of the water tank and the whole machine, when the user needs to add water to the water tank, because the water pump is located inside the water tank and the connection structure with the water tank is relatively complicated, the user has to remove the water pump from the water tank before the water adding operation can be carried out smoothly, which makes the water adding operation inconvenient. The water pump is located in the water tank.

[0057] In order to solve the technical problem in the prior art that a water pump is located inside a water tank, causing inconvenience in operation and poor aesthetics, the present disclosure provides an electrical device.

[0058] Among them, in the electrical equipment disclosed in the present invention, the water pump is arranged inside the fuselage shell, the water outlet end of the docking pipe is located inside the fuselage shell, and docked with the water inlet end of the water pump, the position where the fuselage shell and the water tank are docked is provided with an opening, the water inlet end of the docking pipe is located at the opening position, and is detachably docked with the water outlet end of the water tank, so that the water inlet end of the docking pipe and the water outlet end of the water tank have a separated state and a docked state. That is to say, in the electrical equipment disclosed in the present invention, the water pump is no longer arranged in the water tank, but is arranged in the fuselage shell, and the water pump and the water tank are connected by water through the docking pipe. When it is necessary to add water to the water tank, the water inlet end of the docking pipe is separated from the water outlet end of the water tank, and then the water tank is taken away to add water. The whole process does not require the water pump to be disassembled, and the water pump and its connecting lines will not be exposed, which is convenient for operation, improves the aesthetics, and enhances the user experience.

[0059] In an exemplary embodiment, an electrical device is provided. Figures 1 to 3 As shown, the electrical device may include a body shell 1, a water tank 2, a water pump 3, and a docking pipe 4. The water pump 3 is arranged inside the body shell 1, and the water outlet end of the docking pipe 4 is located inside the body shell 1 and docked with the water inlet end of the water pump 3. An opening is provided at the position where the body shell 1 and the water tank 2 are docked, and the water inlet end of the docking pipe 4 is located at the position of the opening and is detachably docked with the water outlet end of the water tank 2, so that the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 have a separated state and a docked state.

[0060] When it is necessary to add water to the water tank 2, the water inlet end of the docking pipe 4 is separated from the water outlet end of the water tank 2, and then the water tank 2 is taken away to add water. The whole process does not require the removal of the water pump 3, and the water pump 3 and its connecting lines will not be exposed, which is convenient for operation, improves the aesthetics, and enhances the user experience. When the water tank 2 is filled with water, the water outlet end of the water tank 2 can be docked with the water inlet end of the docking pipe 4 again, so as to achieve water communication between the water pump 3 and the water tank 2, so as to supply water to the water-requiring component 5 of the electrical equipment.

[0061] In some embodiments,

[0062] refer to Figures 1 to 3As shown, the electrical device can be a cooling fan, and its water-requiring component 5 can be an evaporator assembly. When the user needs to add water to the water tank 2, first find the connection between the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2. Then, according to the design of the connection structure, if it is a snap connection, gently press the snap to pull the water inlet end of the docking pipe 4 out of the water outlet end of the water tank 2 so that the two are in a separated state. At this time, the user can easily remove the water tank 2 from the body shell 1. Since the water pump 3 is located inside the body shell 1, there is no need to perform any disassembly operation on it. The user takes the water tank 2 to the water source and adds water through the water inlet on the top of the water tank 2. During the water adding process, the water level rise can be visually observed through the transparent or translucent material of the water tank 2. When the water level reaches the required height, stop adding water.

[0063] When the water tank 2 is filled with water, align the water outlet of the water tank 2 with the water inlet of the docking pipe 4 and dock them according to the design of the connection structure. If it is a snap connection, insert the water inlet of the docking pipe 4 into the water outlet of the water tank 2 until you hear a "click" sound from the snap, indicating that the connection is in place; if it is a threaded connection, tighten the nut to ensure a tight connection. At this time, the water inlet of the docking pipe 4 and the water outlet of the water tank 2 are in a docking state, realizing the waterway connection between the water pump 3 and the water tank 2.

[0064] In this embodiment, when the cooling fan is started, the water pump 3 starts to work. Driven by the motor, the impeller of the water pump 3 rotates at a high speed, generating centrifugal force, so that the water in the water tank 2 is sucked into the water pump 3 through the docking pipe 4. Then, the water pump 3 pressurizes the water and delivers it to the evaporator assembly. In the evaporator assembly, the water is evenly distributed on the wet curtain of the evaporation assembly. Through the blowing action of the fan, the water evaporates quickly and absorbs the heat of the surrounding air, thereby reducing the air temperature, realizing the cooling function of the cooling fan, and also achieving a certain humidification effect for the surrounding air.

[0065] It should be noted that the electrical equipment can be not only a cooling fan, but also a humidifier, an air purifier, etc. As long as it needs to be equipped with a water pump 3 and a water tank 2, there is no limitation on the specific equipment type.

[0066] In addition, in this embodiment, the electrical equipment may include a water supply pipe 6, which is located outside the water tank 2, and the water supply pipe 6 is at least partially located inside the fuselage shell 1, so that the water inlet end of the water supply pipe 6 is connected to the water outlet end of the water pump 3, thereby realizing water connection between the water supply pipe 6 and the water pump 3.

[0067] When the electrical equipment is started, the water pump 3 starts to work. The impeller of the water pump 3 rotates at a high speed, generating negative pressure at its water inlet end, and sucking the water in the water tank 2 into the water pump 3 through the rubber hose. Then, the water pump 3 pressurizes the water and discharges it from its water outlet end, and the water flows to the water-requiring component 5 of the electrical equipment through the water supply pipe 6. For example, in a cooling fan, water is transported to the evaporator assembly, where the water evaporates and absorbs heat under the action of the fan, reducing the temperature of the surrounding air and providing a cool and comfortable air environment for the user.

[0068] In this embodiment, the water supply pipe 6 is arranged on the outside of the water tank 2 and is connected to the water pump 3 inside the body shell 1. When the water tank 2 is removed when water needs to be added, there is no interference between the operation of taking the water tank 2 and the water supply pipe 6, and the connection position between the water supply pipe 6 and the water pump 3 will not be exposed, which can greatly improve the operational convenience and overall aesthetics.

[0069] Among them, the electrical equipment may include an electrical connection line of the water pump 3 (not shown in the figure), which is located outside the water tank 2 and at least partially located inside the body shell 1 to achieve electrical connection with the water pump 3. The electrical connection line of the water pump 3 is arranged outside the water tank 2 and connected to the water pump 3 inside the body shell 1. When the water tank 2 is removed when water needs to be added, there is no interference between the operation of taking the water tank 2 and the electrical connection line, and the connection position between the electrical connection line and the water pump 3 will not be exposed, which can greatly improve the convenience of operation and the overall aesthetics.

[0070] For example, when the electrical equipment is assembled, the electrical connection line of the water pump 3 is led out from the wire groove inside the body shell 1, and connected to the electrical connection port of the water pump 3 through the reserved opening. When connecting, first align the waterproof plug with the port of the water pump 3 and insert it, and then hear a "click", indicating that the plug and the port are locked in place, and a stable electrical connection is achieved. At this time, turn on the power, and the current is transmitted to the water pump 3 through the electrical connection line, and the water pump 3 starts to work. For example, in a cold fan, the water pump 3 draws water from the water tank 2 and transports it to the evaporator assembly through the water supply pipe 6. On the evaporator, the water evaporates and absorbs heat under the action of the fan, lowering the temperature of the surrounding air and providing a cool and comfortable air environment for the user.

[0071] When it is necessary to add water to the water tank 2, the user only needs to gently press the buckles around the water tank 2 to remove the water tank 2 from the body shell 1. Since the electrical connection line is located outside the water tank 2 and is well fixed inside the body shell 1, the electrical connection line will not be entangled or interfered with the water tank 2 during the process of taking the water tank 2, and the user can easily take the water tank 2 to the water source for water. After adding water, align the water tank 2 with the installation position on the body shell 1, press the buckle, and reinstall the water tank 2 in place. During the whole process, the connection position between the electrical connection line and the water pump 3 is always inside the body shell 1 and will not be exposed to the outside, which not only ensures the convenience of operation, but also improves the overall aesthetics of the device.

[0072] In the electrical device of this embodiment, the water pump 3 is no longer arranged in the water tank 2, but is arranged in the body shell 1, and the water pump 3 and the water tank 2 are connected by the docking pipe 4. When the water tank 2 needs to be filled with water, the water inlet end of the docking pipe 4 is separated from the water outlet end of the water tank 2, and then the water tank 2 is taken away to add water. The whole process does not require the removal of the water pump 3, and the water pump 3 and its connecting pipes (such as water supply pipes) and connecting lines (such as electrical connecting lines) will not be exposed, which is convenient for operation, improves the aesthetics, and enhances the user experience.

[0073] In an exemplary embodiment, an electrical device is provided. Figures 1 to 5 As shown, in the electrical device of this embodiment, a second docking sealing structure 21 is provided at the water inlet end of the docking pipe 4, and a first docking sealing structure 41 is provided at the water outlet end of the water tank 2.

[0074] Among them, the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 are in a separated state, and the first docking sealing structure 41 seals the water inlet end of the docking pipe 4 to prevent external dust, impurities, etc. from entering the pipeline, and can also prevent water leakage in the docking pipe 4; the second docking sealing structure 21 seals the water outlet end of the water tank 2 to prevent water leakage in the water tank 2, and can also prevent external dust, impurities, etc. from entering the inside of the water tank 2.

[0075] Among them, the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 are in a docking state, and the first docking sealing structure 41 and the second docking sealing structure 21 are docked and connected, so that the docking pipe 4 is connected with the water tank 2, thereby realizing the water path connection between the water pump 3 and the water tank 2, which is convenient for the water pump 3 to drive the water in the water tank 2 to the water-requiring component 5.

[0076] Among them, the first docking sealing structure 41 may include a first water valve and a first elastic member (such as a spring). The water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 are in a separated state. The first water valve seals the water inlet end of the docking pipe 4 under the elastic force of the first elastic member to form a reliable seal.

[0077] In some embodiments,

[0078] The first water valve may include a valve seat and a circular rubber valve sheet, and the first elastic member is a spring. In the valve seat at the water inlet end of the docking pipe 4, one end of the spring is fixed to the bottom of the valve seat, and the other end is connected to the rubber valve sheet. When the docking pipe 4 and the water tank 2 are in a separated state, the elastic force of the spring presses the rubber valve sheet tightly against the water inlet of the valve seat, thereby sealing the water inlet end of the docking pipe 4. This can effectively prevent external dust, impurities, etc. from entering the docking pipe 4, and keep the inside of the pipe clean.

[0079] In this embodiment, the size of the rubber valve sheet can be adapted to the water inlet of the valve seat at the water inlet end of the connecting pipe 4 and the structure of the water outlet end of the water tank 2, and can completely cover the water inlet to achieve effective sealing. The thickness of the valve sheet is about 2 mm, which ensures that the valve sheet can be effectively deformed and opened when subjected to a certain pressure, and can maintain its own shape and elasticity under normal conditions to ensure sealing performance.

[0080] A small protrusion structure may be provided on one side of the valve plate (the side connected to the spring). This protrusion is for the convenience of connecting with the spring. The shape of the protrusion may be hemispherical or cylindrical. When a cylindrical protrusion is used, a small hole may be provided in the center of the protrusion for passing one end of the spring or connecting with the hook structure of the spring.

[0081] The edge of the rubber valve sheet can have a certain curvature and smoothness. This design allows the valve sheet to fit better when in contact with the water inlet of the valve seat, forming a tight seal. The rubber material of the edge is relatively soft and can adaptively deform according to the slight irregular shape of the water inlet of the valve seat, further enhancing the sealing effect.

[0082] It should be noted that, in addition to the above-mentioned structure, the first sealing docking structure may also be other structures, which is not limited to this.

[0083] Among them, the second docking sealing structure 21 includes a second water valve and a second elastic member (such as a spring). The water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 are in a separated state. The second water valve seals the water inlet end of the docking pipe 4 under the elastic force of the second elastic member to form a reliable seal.

[0084] It should be noted that, in this embodiment, the first butt sealing structure 41 and the second sealing structure may be the same or different, and this is not limited.

[0085] For example, the second water valve may also include a circular rubber valve sheet, and the second elastic member may also be a spring. In the chamber at the water outlet of the water tank 2, one end of the spring is fixed to the bottom of the chamber, and the other end is connected to the rubber valve sheet. When the docking pipe 4 is separated from the water tank 2, the spring pushes the rubber valve sheet to close the water outlet 912 of the chamber to prevent water in the water tank 2 from leaking.

[0086] In addition, in this embodiment, the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 are in a docking state, and the water tank 2 is located above the water inlet end of the docking pipe 4. Under the action of gravity of the water tank 2, the first water valve and the second water valve are driven to move to connect the water inlet end of the docking pipe 4 with the water outlet end of the water tank 2.

[0087] For example, the first elastic member drives the first water valve to seal the water inlet end of the docking pipe 4 as the first elastic force, and the second elastic member drives the second water valve to seal the water outlet end of the water tank 2 as the second elastic force. The gravity of the water tank 2 is greater than the sum of the first elastic force and the second elastic force, so that when the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 are in a docking state, the first water valve and the second water valve are driven to move under the action of the gravity of the water tank 2 to connect the water inlet end of the docking pipe 4 with the water outlet end of the water tank 2.

[0088] In some embodiments, when it is necessary to use the electrical equipment and dock the water tank 2 with the docking pipe 4, the user picks up the water tank 2 and aligns it with the water tank 2 placement position on the top of the body shell 1, and then slowly lowers the water tank 2. During the descent of the water tank 2, the water outlet end of the water tank 2 gradually approaches the water inlet end of the docking pipe 4. After the two are in contact, as the water tank 2 continues to descend, the gravity of the water tank 2 acts on the valve plate of the second water valve to overcome the elastic force of the spring in the second docking sealing structure 21, so that the valve plate of the second water valve moves upward and opens the water outlet 912 of the water tank 2. At the same time, the gravity of the water tank 2 is also transmitted to the first water valve through the water inlet end of the docking pipe 4. Since the gravity of the water tank 2 is greater than the elastic force of the spring in the valve seat of the first water valve, the piston of the first water valve moves downward, thereby driving the rubber valve plate to move downward and opening the water inlet of the valve seat. In this way, driven by the gravity of the water tank 2, the first water valve and the second water valve both move to a state where the water inlet end of the docking pipe 4 is connected to the water outlet end of the water tank 2, and the water in the water tank 2 flows into the docking pipe 4 under the action of gravity, and is then pumped by the water pump 3 and transported to the water-requiring component 5 of the electrical equipment. For example, in a desktop cooling fan, water is transported to the wet curtain of the evaporator assembly. Under the action of the fan, the water evaporates and absorbs heat, lowering the temperature of the surrounding air and providing cool wind for the user. For another example, in a humidifier, water is transported to the atomizing device, atomized into tiny water droplets and sprayed out to increase the humidity of the air.

[0089] The water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 are in a docking state, and the water inlet end of the docking pipe is inserted into the water outlet end of the water tank 2, or the water outlet end of the water tank 2 is inserted into the water inlet end of the docking pipe, so as to achieve reliable docking between the two. In addition, the electrical device may include a sealing member 8, and when the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 are in a docking state, the sealing member 8 may be located in the gap between the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2, so as to achieve sealed docking between the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2.

[0090] For example, when the water outlet of the water tank 2 is an outwardly convex plug, the seal 8 can be first installed in the annular groove on the outer wall of the plug. Then, align the water inlet end connecting sleeve of the docking pipe 4 with the plug of the water tank 2, and slowly put the connecting sleeve on the plug. During the insertion process, the annular protrusion on the inner wall of the connecting sleeve will squeeze the seal 8, causing the seal 8 to elastically deform and fill the gap between the connecting sleeve and the plug. When the connecting sleeve is completely sleeved on the plug, the docking pipe 4 and the water tank 2 are fixed by a simple snap-fit ​​structure or threaded connection to prevent it from accidentally falling off. At this time, the seal 8 forms a reliable seal in the squeezed state to ensure that the water in the water tank 2 will not leak.

[0091] For another example, when the water outlet of the water tank 2 is a concave chamber, first place the seal 8 in the annular groove on the inner wall of the chamber. Then, align the water inlet end plug rod of the docking pipe 4 with the chamber of the water tank 2, and gently insert the plug rod into the chamber. During the insertion process, the annular protrusion on the outer wall of the plug rod will squeeze the seal 8, causing it to deform and fill the gap between the plug rod and the chamber. After being inserted into place, the two are firmly connected by snaps or other fixing methods to achieve sealed docking.

[0092] It should be noted that the sealing structure may be arranged in other ways besides the above-mentioned arrangement, and this is not limited.

[0093] In some embodiments, the seal 8 may include a sealing ring, the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 are in a docking state, the water inlet end of the docking pipe is inserted into the water outlet end of the water tank 2, the sealing ring is sleeved on the radial outer side of the water outlet end of the docking pipe 4, and the water outlet end of the water tank 2 is sleeved on the radial outer side of the sealing ring. In this embodiment, for example, when the docking pipe 4 needs to be docked with the water tank 2, the sealing ring can be sleeved on the water inlet end connecting sleeve of the docking pipe 4. Then, the water inlet end of the docking pipe 4 is aligned with the outer convex cylindrical interface of the water tank 2 and slowly inserted. During the insertion process, the interface of the water tank 2 is gradually sleeved into the sealing ring, and the sealing ring is elastically deformed by extrusion, and its inner diameter becomes smaller, and it fits tightly on the outer wall of the connecting sleeve of the docking pipe 4 and the inner wall of the interface of the water tank 2, filling the gap between the two. When inserted into place, the sealing ring forms a reliable seal under double extrusion to ensure that the water in the water tank 2 will not leak.

[0094] In some embodiments, the seal 8 may include a sealing ring, the water inlet end of the docking pipe 4 and the water outlet end of the water tank 2 are in a docking state, the water outlet end of the water tank 2 is inserted into the water inlet end of the docking pipe, the sealing ring is sleeved on the radial outer side of the water outlet end of the water tank 2, and the water outlet end of the docking pipe 4 is sleeved on the radial outer side of the sealing ring. In this embodiment, for example, when the docking pipe 4 needs to be docked with the water tank 2, the sealing ring is first sleeved on the outer wall of the water outlet end of the concave chamber of the water tank 2. Then, the plug rod of the water inlet end of the docking pipe 4 is aligned with the chamber of the water tank 2 and gently inserted. During the insertion process, the plug rod of the docking pipe 4 is gradually inserted into the sealing ring, the sealing ring is squeezed and deformed, and its inner diameter becomes smaller, and it fits tightly on the outer wall of the chamber of the water tank 2 and the inner wall of the plug rod of the docking pipe 4, filling the gap between the two. After the insertion is completed, the water tank 2 and the docking pipe 4 are fixed by the fixing structure of the fuselage shell 1, and the sealing ring is effectively sealed, so that the waterway between the water tank 2 and the docking pipe 4 is connected and leak-free.

[0095] In this embodiment, through the first docking sealing structure 41, the second docking sealing structure 21 and the sealing member 8, a good sealing effect can be achieved whether the docking pipe 4 is inserted into the water tank 2 or the water tank 2 is inserted into the docking pipe 4, which can effectively prevent water leakage from damaging the internal circuits and components of the electrical equipment, thereby improving the safety and stability of the equipment and extending the service life of the equipment.

[0096] In an exemplary embodiment, an electrical device is provided. Figures 1 to 3 as well as Figure 6 and Figure 7 As shown, the electrical equipment of this embodiment may include a sewer pipe 7 and a wave-breaking structure 9, the water outlet end of the sewer pipe 7 is connected to the water inlet end of the water tank 2, the wave-breaking structure 9 is fixedly connected to the water inlet end of the water tank 2, and the wave-breaking structure 9 is at least partially arranged on the circumferential outer side of the water outlet end of the sewer pipe 7.

[0097] For example, when the electrical equipment is a cooling fan, the evaporator assembly of the cooling fan is connected to the water pump 3 through the upper water pipe 6, that is, the upper water pipe 6 is used to supply water to the evaporator assembly; the evaporator assembly and the water tank 2 can be connected with the lower water pipe 7, that is, the lower water pipe 7 is used to drain the evaporator assembly, and the water discharged from the evaporator assembly is transported to the water tank 2 to realize the recycling of water.

[0098] It should be noted that when the water from the sewer pipe 7 flows into the water tank 2, if there is no wave-breaking structure 9, the water flow directly impacts the water surface in the water tank 2, which will produce a large impact force. The wave-breaking structure 9 is partially arranged on the circumferential outer side of the water outlet end of the sewer pipe 7, which can buffer the water flow when it flows out of the sewer pipe 7. For example, the wave-breaking structure 9 can be a sleeve with guide blades, and the water flow hits the guide blades, its speed and direction are changed, and the energy is dispersed. This is like setting an obstacle in the river, the water flow hits the obstacle, the impact force is weakened, and the waves formed in the water tank 2 are reduced. In some electrical equipment that requires high water level monitoring accuracy (such as a cooling fan with a liquid level sensor), this wave reduction effect can effectively prevent the misjudgment of the liquid level due to water surface fluctuations.

[0099] In addition, when the water flow speed is fast or the outlet end of the sewer pipe 7 is at a certain height from the water surface of the water tank 2, water is easy to splash out. The wave-proof structure 9 plays a blocking role on the circumferential outer side, so that the splashing water is confined inside the wave-proof structure 9. For example, the wave-proof structure 9 may include a fence with a certain height and curvature, like a small dam. Even if the water flow has a tendency to splash, it will be blocked by the fence and fall back into the water tank 2 to prevent the water from overflowing the water tank 2, thereby avoiding damage to electrical equipment or surrounding items due to water overflow. For example, a dehumidifier will produce a large amount of condensed water and quickly flow into the electrical equipment of the water tank 2. This function of preventing water from overflowing is particularly important.

[0100] Among them, the wave-proof structure 9 can be designed in the form of a spiral or inclined diversion channel to guide the water flow into the water tank 2 in a specific way. When the water flows into the water tank 2 along these diversion channels, its flow is more orderly. For example, the spiral diversion channel can make the water flow slowly into the water tank 2 like a spiral, gradually converting the kinetic energy of the water flow into potential energy, and avoiding the water flow from concentrating on one position and generating large waves. This orderly way of water flow entering helps to maintain the stability of the water surface in the water tank 2. For some electrical equipment that requires a stable water supply environment (such as an air purifier with a water circulation system), it can ensure the normal water circulation inside the equipment.

[0101] In addition, some water tanks 2 may be equipped with components such as sensors and filters. The wave-proof structure 9 surrounds the outlet end of the sewer pipe 7 in a circumferential direction to prevent the water flow from directly impacting these components. For example, in a water tank 2 with a water quality detection sensor, if there is no wave-proof structure 9, the direct impact of the water flow may damage the sensor or affect its detection accuracy. The wave-proof structure 9 reduces this risk by buffering the water flow, prolongs the service life of the internal components, and improves the overall reliability of the electrical equipment.

[0102] The wave-proof structure 9 may include a connected clamping portion 92 and a wave-proof portion 91. The clamping portion 92 and the wave-proof portion 91 may be integrally formed or fixedly connected in other ways, which is not limited thereto. The clamping portion 92 is clamped and connected to the water inlet end of the water tank 2 to achieve fixed assembly between the wave-proof structure 9 and the water tank 2. The wave-proof portion 91 is constructed as a groove-shaped structure, and the water outlet end of the sewer pipe 7 is located on the side where the groove of the groove-shaped structure is located, and is deep in the groove-shaped structure, so that the wave-proof portion 91 can better achieve the wave-proof effect.

[0103] When the electrical equipment runs and generates water that needs to be discharged, the water pump 3 is started to extract water from the source and transport it through the sewer pipe 7. After the water flows out from the outlet end of the sewer pipe 7, it directly enters the groove structure of the wave-proof structure 9. Due to the blocking and buffering effect of the groove structure, the impact force of the water flow is first weakened. Then, the water flows along the inner wall of the groove structure, thereby effectively reducing the waves generated when the water flow directly hits the water surface of the water tank 2.

[0104] The bottom wall of the groove-like structure may include a drainage area 911, which may be the entire bottom wall or a partial area of ​​the bottom wall, and is not limited thereto. A water outlet 912 is provided on the groove-like structure, and the drainage area 911 is inclined downward from the direction away from the water outlet 912 to the direction close to the water outlet 912, so that the water discharged from the sewer pipe 7 can be more smoothly drained to the water outlet 912 and discharged into the water tank 2.

[0105] Among them, the drainage area 911 is provided with a plurality of drainage ribs (not shown in the figure), the plurality of drainage ribs are dispersedly arranged, and the drainage ribs extend from a direction away from the water outlet 912 to a direction close to the water outlet 912, so as to better achieve the drainage effect.

[0106] In some embodiments,

[0107] The wave-proof structure 9 includes a connected clamping part 92 and a wave-proof part 91. The clamping part 92 may include a clamping groove, and the wave-proof structure 9 may be clamped into the clamping groove of the clamping part 92 through the upper edge of the water tank 2 to achieve fixed assembly with the water tank 2. The wave-proof part 91 is constructed as a groove-shaped structure, and the groove-shaped structure may be semi-cylindrical. The bottom wall of the groove-shaped structure includes a drainage area 911, which is most of the bottom wall, extending from one end of the groove-shaped structure to the other end, and occupies about two-thirds of the bottom wall area on the side close to the water outlet 912. A plurality of drainage ribs are arranged on the drainage area 911, and the drainage ribs are triangular in cross section. The drainage ribs extend from away from the water outlet 912 to close to the water outlet 912, and are dispersedly arranged at an angle of 30 degrees to 60 degrees between each other. A circular water outlet 912 is arranged on the groove-shaped structure, which is located at the lowest point of the drainage area 911. From the direction away from the water outlet 912 to the direction close to the water outlet 912, the drainage area 911 is inclined downward, and the inclination angle is 10 degrees to 15 degrees, so that the water discharged from the sewer pipe 7 can be more smoothly drained to the water outlet 912 and discharged into the water tank 2.

[0108] When the electrical equipment is running, the water pump 3 delivers water to the groove structure of the wave-proof structure 9 through the sewer pipe 7. The water flow is first blocked and buffered by the surrounding wall of the groove structure, which reduces the initial impact of the water flow. Then, the water flow diffuses in the groove structure and flows to the drainage area 911. Since the drainage area 911 is tilted downward from the direction away from the water outlet 912 to the direction close to the water outlet 912, the water flow naturally flows in the direction of the water outlet 912 under the action of gravity. At the same time, the drainage ribs further guide the water flow, divide the water flow into multiple smaller water flows, and make it converge to the water outlet 912 in an orderly manner along the direction of the drainage ribs. For example, in a dehumidifier, a large amount of condensed water can quickly and smoothly enter the water tank 2 through the drainage system of the wave-proof structure 9, and no large waves or splashes will be formed in the water tank 2. In the water circulation process of the cooling fan, the water returning from the evaporator can also smoothly enter the water tank 2 through the wave-proof structure 9, ensuring the stability of the water level in the water tank 2, which is conducive to the normal operation of the equipment.

[0109] It should be noted that the wave-breaking structure 9 may be other structures besides the structure described above, as long as it can achieve the wave-breaking effect, and its specific structure is not limited.

[0110] In an exemplary embodiment, an electrical device is provided, and the electrical device may be a cooling fan. Figures 1 to 7 As shown, the cooling fan may include a water tank 2, a body shell 1, a water pump 3, and a docking pipe 4. The docking pipe 4 may include a docking pipe or other docking structures, which are not limited thereto.

[0111] Among them, the function / role of the water tank 2 is to store water, and its basic property is a watertight rigid body. The relationship between the water tank 2 and the docking pipe 4 is a water docking connection. The water tank 2 can be fixedly assembled with the fuselage shell 1 and can be removed from the fuselage shell 1. The water tank 2 and the docking pipe 4 are respectively provided with docking sealing structures, and the docking sealing structure at the water outlet end of the water tank 2 can be recorded as a first docking sealing structure 41, and the docking sealing structure at the water inlet end of the docking pipe 4 can be recorded as a second docking sealing structure 21.

[0112] When the two docking sealing structures are not docked, the water valves seal the corresponding water tank 2 and docking pipe 4 respectively under the force of the spring, ensuring that when the user takes the water tank 2 away to add water, the water tank 2 and the docking pipe 4 will not leak. When the docking sealing structures are docked, the water valves on the water tank 2 and the docking pipe 4 are opened, so that the water path between the water tank 2 and the docking pipe is connected, and the water in the water tank 2 can flow into the docking pipe 4.

[0113] The function / role of the docking pipe 4 is to connect the water tank 2 and the water pump 3. The setting position of the docking pipe 4 is the bottom of the fuselage shell 1, and its basic property is a sealed and watertight rigid body. The relationship between the docking pipe 4 and the water pump 3 is a sealed connection. The relationship between the docking pipe 4 and the water tank 2 is water docking. Among them, the water docking relationship between the docking pipe 4 and the water tank 2 is a key feature to solve the problem of hiding the water pump 3 and the connected water pipes and water pump 3 wires (such as electrical connecting wires). The reason for this arrangement is that after the water pump 3 is connected to the docking pipe 4, the water pump 3 and most of the docking pipe 4 can be hidden inside the fuselage shell 1, and only the water inlet end docked with the water tank 2 needs to be exposed. Compared with the related art, such a setting can bring about hiding the water pump 3 and the connected water pipes and water pump 3 wires (such as electrical connecting wires).

[0114] It should be noted that the water pump 3 and the connected water pipes and water pump 3 wires (such as electrical connection wires) in this embodiment are all hidden inside the fuselage shell 1, and do not need to be directly connected to the water tank 2. Only the docking port of the fuselage shell 1 is exposed to realize the key function of connecting the water circuit of the whole machine. In the related art, the water tank 2 without the docking pipe 4 in this embodiment needs to be directly connected to the water pump 3. After the water tank 2 is taken out, the water pump 3 and the connected water pipes and water pump 3 wires (such as electrical connection wires) must be pulled out together, which has poor aesthetics and safety. Alternatively, the water tank 2 is fixed to the fuselage shell 1, and the water pump 3 and the like can also be hidden, but the water tank 2 cannot be taken out to add water, which is inconvenient to add water.

[0115] Among them, in this embodiment, there is a spring thrust between the water valve and the water tank 2 / the docking pipe, so that the water valve is pushed in the direction of the water outlet end of the sealed water tank 2 / the water inlet end of the docking pipe 4. After the water tank 2 is docked with the docking pipe 4, the water tank 2 is pressed down by gravity and docked with the docking pipe 4 in place, that is, the water outlet end of the water tank 2 and the water inlet end of the docking pipe 4 are coaxially inserted into each other's part, and the gravity of the water tank 2 is greater than the spring thrust. After docking, the two water valves will push each other apart to achieve waterway connection. It should be noted that a sealing ring may be provided on the water tank 2 or the docking pipe 4, and the sealing ring can block the gap between the water outlet end of the water tank 2 and the water inlet end of the docking pipe 4 after the docking is completed to achieve docking sealing. Before docking, the two water valves each seal the corresponding opening.

[0116] In addition, a sealing tube 10 may be provided between the water inlet end of the water pump 3 and the water outlet end of the connecting pipe 4, and the sealing tube 10 may block the gap between the water inlet end of the water pump 3 and the water outlet end of the connecting pipe 4 to prevent water leakage, and water may be allowed to flow between the two. Alternatively, the connecting pipe 4 itself may be used as the sealing tube 10 to achieve sealing, which is not limited thereto.

[0117] The function of the wave-breaking plate is to drain the return water. It is set at the upper part of the water tank 2 and is fixedly assembled with the water tank 2. The outlet end of the sewer pipe 7 is above the drainage area 911 of the wave-breaking structure 9. The drainage area 911 can reduce the return speed of the return water into the water tank 2 to reduce the water flow impact noise.

[0118] It should be noted that the wave-proof structure 9 and the water tank 2 can be fixedly assembled by buckles, and the wave-proof structure 9 may include inner wave-proof ribs, assembled buckles and the structure corresponding to the above-mentioned drainage area 911. At least part of the drainage area 911 may have an inclination angle, with an angle greater than 5 degrees with the horizontal plane, and a gap for water to pass through is left between the drainage area 911 and the water tank 2 to form a water outlet 912. The minimum cross-section of the above-mentioned gap should be larger than the cross-sectional area of ​​the water outlet 912 of the return water sewer pipe 7 to avoid the accumulation of return water.

[0119] In this embodiment, the water tank 2 is loaded onto the fuselage shell 1 after water is added, and after the water tank 2 is docked with the docking pipe 4, the water channels of the water tank 2 and the docking pipe 4 are automatically connected, and the water in the water tank 2 flows into the docking pipe 4. In the process of loading the water tank 2 into the fuselage shell 1, the water inlet end of the docking pipe 4 is inserted into the water outlet end of the water tank 2, or the water outlet end of the water tank 2 is inserted into the water inlet end of the docking pipe 4, and the two water valves are gradually pushed open during the loading process. After the water valves are installed, they are all pushed open, and the water tank 2 flows into the docking pipe 4 from the docking point, completing the docking and circulation of water. A sealing ring can be provided between the water outlet end under the water tank 2 and the water inlet end of the docking pipe 4 for sealing to avoid water overflow after docking.

[0120] After the water pump 3 is turned on, the water pump 3 pumps out the water in the docking pipe 4 and delivers it to the evaporator assembly through the upper water pipe 6. The unevaporated return water flows from the lower water pipe 7 to the wave-breaking structure 9, and is drained into the water tank 2 through the drainage area 911, forming a complete waterway with the water pump 3. It should be noted that the drainage area 911 can be replaced by vertical drainage ribs or drainage columns, which is not limited to this, as long as the drainage effect is achieved.

[0121] Among them, most of the water pump 3 and its electrical connections, water supply pipe 6, water discharge pipe 7, docking pipe 4, etc. are hidden in the body shell 1, rather than being located in the water tank 2. After taking away the water tank 2, the user will only see the exposed part of the docking pipe 4 and the structure docking with the water tank 2, which reduces safety hazards, improves operational convenience, and greatly optimizes the overall appearance.

[0122] In the electrical device of this embodiment, the water pump 3 is no longer arranged in the water tank 2, but is arranged in the body shell 1, and the water pump 3 and the water tank 2 are connected by the docking pipe 4. When the water tank 2 needs to be filled with water, the water inlet end of the docking pipe 4 is separated from the water outlet end of the water tank 2, and then the water tank 2 is taken away to add water. The whole process does not require the removal of the water pump 3, and the water pump 3 and its connecting pipes (such as water supply pipes) and connecting lines (such as electrical connecting lines) will not be exposed, which is convenient for operation, improves the aesthetics, and enhances the user experience.
