Description

Technical Field

[0001] This disclosure relates to the field of electrical equipment technology, and more particularly to an electrical device. Background Technology

[0002] As people's living standards improve, electrical appliances such as air coolers are being used more and more widely in daily life and work environments. These appliances use water pumps to deliver water from a tank to specific components, thereby achieving functions such as cooling and humidification.

[0003] However, a significant design flaw exists in many electrical appliances currently on the market: their water pumps are mostly installed directly inside the water tank. For appliances where the water tank and the main unit are not integrated, when users need to add water, the pump is located inside the tank, and the connection structure is relatively complex. Users must first remove the pump from the tank to add water, causing inconvenience. Furthermore, with the pump inside the tank, the connecting pipes and electrical wires are frequently exposed during the water-adding process, making the internal components of the appliance appear cluttered and affecting its aesthetics.

[0057] In order to solve the technical problems of inconvenience in operation and poor aesthetics caused by the water pump being located inside the water tank in the prior art, this disclosure provides an electrical device.

[0058] In this electrical device, the water pump is housed inside the casing. The outlet of the connecting pipe is also located inside the casing and connects to the inlet of the water pump. An opening is provided at the junction of the casing and the water tank. The inlet of the connecting pipe is located at this opening and can be detachably connected to the outlet of the water tank, allowing for both detached and connected states. In other words, the water pump is no longer housed inside the water tank but is instead located within the casing. The water pump and water tank are connected via a connecting pipe. When water needs to be added, the inlet of the connecting pipe is separated from the outlet of the water tank, and the water tank can be removed for filling. The entire process requires no disassembly of the water pump and avoids exposing the pump and its wiring, thus facilitating operation, improving aesthetics, and enhancing the user experience.

[0059] In one exemplary embodiment, an electrical device is provided. (Reference) Figures 1 to 3 As shown, the electrical equipment may include a housing 1, a water tank 2, a water pump 3, and a connecting pipe 4. The water pump 3 is located inside the housing 1, and the outlet of the connecting pipe 4 is located inside the housing 1 and is connected to the inlet of the water pump 3. An opening is provided at the location where the housing 1 connects to the water tank 2, and the inlet of the connecting pipe 4 is located at the opening and can be detachably connected to the outlet of the water tank 2, so that the inlet of the connecting pipe 4 and the outlet of the water tank 2 can be in a detached state and a connected state.

[0060] When water needs to be added to water tank 2, simply disconnect the inlet end of the connecting pipe 4 from the outlet end of water tank 2, then remove water tank 2 to add water. The entire process does not require disassembling water pump 3, nor does it expose water pump 3 and its connecting wires, making it convenient to operate, improving aesthetics, and enhancing the user experience. Once water tank 2 is full, the outlet end of water tank 2 can be reconnected to the inlet end of the connecting pipe 4, thus establishing a water connection between water pump 3 and water tank 2 to supply water to the water-requiring components 5 of electrical equipment.

[0061] In some implementations...

[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 locate the connection between the inlet of the connecting pipe 4 and the outlet of the water tank 2. Then, according to the design of the connection structure, if it is a snap-fit ​​connection, gently press the snap to pull the inlet of the connecting pipe 4 from the outlet of the water tank 2, so that the two are separated. At this time, the user can easily remove the water tank 2 from the housing 1. Since the water pump 3 is located inside the housing 1, no disassembly is required. 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 can be observed directly through the transparent or semi-transparent material of the water tank 2. When the water level reaches the required height, stop adding water.

[0063] After water tank 2 is filled with water, align the outlet of water tank 2 with the inlet of the connecting pipe 4 and connect them according to the design of the connection structure. If it is a snap-fit ​​connection, insert the inlet of the connecting pipe 4 into the outlet of water tank 2 until you hear a "click" sound, indicating that the connection is in place; if it is a threaded connection, tighten the nut to ensure a tight connection. At this point, the inlet of the connecting pipe 4 and the outlet of water tank 2 are in a connected state, realizing the water circuit connection between water pump 3 and water tank 2.

[0064] In this embodiment, when the evaporator fan starts, the water pump 3 begins to work. Driven by the motor, the impeller of the water pump 3 rotates at high speed, generating centrifugal force, which draws water from the water tank 2 into the water pump 3 through the connecting 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 evaporator assembly. Through the blowing action of the fan, the water evaporates rapidly, absorbing heat from the surrounding air, thereby lowering the air temperature and realizing the cooling function of the evaporator fan. At the same time, it also has a certain humidifying effect on the surrounding air.

[0065] It should be noted that the electrical equipment can be a fan, a humidifier, an air purifier, etc., as long as it requires a water pump 3 and a water tank 2. There are no restrictions on the specific type of equipment.

[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 at least partially inside the housing 1, so that the inlet end of the water supply pipe 6 is connected to the outlet end of the water pump 3, thereby realizing the water circuit communication between the water supply pipe 6 and the water pump 3.

[0067] When the electrical equipment is started, water pump 3 begins to work. The impeller of water pump 3 rotates at high speed, generating negative pressure at its inlet, drawing water from water tank 2 into water pump 3 through a rubber hose. Then, water pump 3 pressurizes the water and discharges it from its outlet. The water flows through water supply pipe 6 to the water-requiring components 5 of the electrical equipment. For example, in an air cooler, water is delivered to the evaporator assembly. 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.

[0068] In this embodiment, the water supply pipe 6 is located outside the water tank 2 and connected to the water pump 3 inside the housing 1. When water needs to be added, the operation of removing the water tank 2 does not interfere with the operation of removing the water tank 2 and the water supply pipe 6. The connection position between the water supply pipe 6 and the water pump 3 will not be exposed, which can greatly improve the convenience of operation and the overall aesthetics.

[0069] The electrical equipment may include an electrical connection cable (not shown in the figure) for the water pump 3. The electrical connection cable is located outside the water tank 2 and at least partially inside the housing 1 to achieve electrical connection with the water pump 3. Because the electrical connection cable for the water pump 3 is located outside the water tank 2 and connected to the water pump 3 inside the housing 1, there is no interference between the operation of removing the water tank 2 and the electrical connection cable when adding water, and the connection point between the electrical connection cable and the water pump 3 is not exposed. This significantly improves operational convenience and overall aesthetics.

[0070] For example, during the assembly of electrical equipment, the electrical connection cable of water pump 3 is led out from the wire groove inside the housing 1 and connected to the electrical connection port of water pump 3 through the reserved opening. During connection, first align the waterproof plug with the port of water pump 3 and insert it. A "click" sound indicates that the plug and port are locked in place, achieving a stable electrical connection. At this point, the power is turned on, and current is transmitted to water pump 3 through the electrical connection cable, and water pump 3 begins to work. For example, in an air cooler, water pump 3 draws water from water tank 2 and delivers 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 water needs to be added to water tank 2, the user simply needs to gently press the latches around water tank 2 to remove it from the housing 1. Since the electrical connection cable is located outside water tank 2 and securely fixed inside housing 1, it will not tangle or interfere with water tank 2 during removal, allowing the user to easily carry it to a water source for refilling. After refilling, align water tank 2 with the mounting position on housing 1 and press the latches to reinstall it. Throughout the entire process, the connection between the electrical connection cable and water pump 3 remains inside housing 1, ensuring ease of operation and enhancing the overall aesthetics of the equipment.

[0072] In this embodiment of the electrical equipment, the water pump 3 is no longer located inside the water tank 2, but is located inside the housing 1. The water pump 3 and the water tank 2 are connected by a connecting pipe 4. When water needs to be added to the water tank 2, the inlet end of the connecting pipe 4 is separated from the outlet end of the water tank 2, and then the water tank 2 can be removed to add water. The entire process does not require disassembling the water pump 3, and it does not expose the water pump 3 and its connecting pipes (such as water inlet pipes) and connecting wires (such as electrical connection wires), which is convenient to operate, improves aesthetics, and enhances the user experience.

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

[0074] In this configuration, the inlet end of the connecting pipe 4 and the outlet end of the water tank 2 are in a separated state. The first connecting sealing structure 41 seals the inlet end of the connecting pipe 4 to prevent external dust, impurities, etc. from entering the pipe and also to prevent water leakage in the connecting pipe 4. The second connecting sealing structure 21 seals the outlet end of the water tank 2 to prevent water leakage in the water tank 2 and also to prevent external dust, impurities, etc. from entering the interior of the water tank 2.

[0075] In this configuration, the inlet end of the connecting pipe 4 and the 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 to each other, so that the connecting pipe 4 and the water tank 2 are connected, thereby realizing the water circuit connection between the water pump 3 and the water tank 2, which makes it easier for the water pump 3 to drive the water in the water tank 2 to the water-requiring component 5.

[0076] The first docking sealing structure 41 may include a first water valve and a first elastic element (e.g., a spring). When the water inlet end of the docking pipeline 4 is separated from the water outlet end of the water tank 2, the first water valve seals the water inlet end of the docking pipeline 4 under the elastic force of the first elastic element to form a reliable seal.

[0077] In some implementations...

[0078] The first water valve may include a valve seat and a circular rubber valve plate, with a spring as the first elastic element. Inside the valve seat at the water inlet of the connecting 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 plate. When the connecting pipe 4 is separated from the water tank 2, the spring force presses the rubber valve plate tightly against the water inlet of the valve seat, thereby sealing the water inlet of the connecting pipe 4. This effectively prevents external dust, impurities, etc., from entering the connecting pipe 4, keeping the inside of the pipe clean.

[0079] In this embodiment, the size of the rubber valve plate is adapted to the structure of the inlet of the valve seat at the water inlet end of the connecting pipeline 4 and the outlet end of the water tank 2, so as to completely cover the water inlet and achieve effective sealing. The thickness of the valve plate is about 2mm. This thickness ensures that the valve plate can effectively deform and open under certain pressure, while maintaining its shape and elasticity under normal conditions to ensure sealing performance.

[0080] A small protrusion can be provided on one side of the valve plate (the side connected to the spring). This protrusion is for easy connection with the spring. The protrusion can be hemispherical or cylindrical. When using a cylindrical protrusion, a small hole can be provided in the center of the protrusion for one end of the spring to pass through or for connection to the spring's hook structure.

[0081] The edges of the rubber valve disc can have a certain degree of curvature and smoothness. This design allows the valve disc to fit better when in contact with the valve seat inlet, forming a tight seal. The relatively soft rubber material at the edges can adaptively deform according to the slight irregularities in the valve seat inlet, further enhancing the sealing effect.

[0082] It should be noted that the first sealing and docking structure can be any other structure besides the one described above, and there is no limitation on this.

[0083] The second docking sealing structure 21 includes a second water valve and a second elastic element (e.g., a spring). When the water inlet end of the docking pipe 4 is separated from the water outlet end of the water tank 2, the second water valve seals the water inlet end of the docking pipe 4 under the elastic force of the second elastic element to form a reliable seal.

[0084] It should be noted that in this embodiment, the first mating sealing structure 41 and the second sealing structure may be the same or different, and there is no limitation on this.

[0085] For example, the second water valve may also include a circular rubber valve plate, and the second elastic element is also a spring. In the chamber at the 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 plate. When the connecting pipe 4 is separated from the water tank 2, the spring pushes the rubber valve plate to close the outlet 912 of the chamber, preventing water leakage from the water tank 2.

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

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

[0088] In some implementations, when electrical equipment needs to be used and the water tank 2 is connected to the connecting 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 housing 1, then slowly lowers the water tank 2. During the descent of the water tank 2, the outlet of the water tank 2 gradually approaches the inlet of the connecting pipe 4. Upon contact, as the water tank 2 continues to descend, its weight acts on the valve plate of the second water valve, overcoming the spring force in the second docking sealing structure 21, causing the valve plate of the second water valve to move upward and open the outlet 912 of the water tank 2. Simultaneously, the weight of the water tank 2 is also transmitted to the first water valve through the inlet of the connecting pipe 4. Because the weight of the water tank 2 is greater than the spring force in the valve seat of the first water valve, the piston of the first water valve moves downward, thereby causing the rubber valve plate to move downward and opening the inlet of the valve seat. Thus, driven by the gravity of water tank 2, both the first and second water valves move to connect the inlet of the connecting pipe 4 with the outlet of water tank 2. Water in water tank 2 flows into connecting pipe 4 under gravity, and is then pumped by water pump 3 and delivered to the water-requiring components 5 of electrical equipment. For example, in a desktop air cooler, water is delivered to the evaporator assembly's wet curtain; under the fan's action, the water evaporates and absorbs heat, lowering the surrounding air temperature and providing cool air to the user. As another example, in a humidifier, water is delivered to the atomizing device, where it is atomized into tiny water droplets and sprayed out, increasing air humidity.

[0089] In this configuration, the inlet end of the connecting pipe 4 and the outlet end of the water tank 2 are in a mating state, with the inlet end of the connecting pipe inserted into the outlet end of the water tank 2, or vice versa, to achieve a reliable connection between the two. Additionally, the electrical equipment may include a sealing element 8. When the inlet end of the connecting pipe 4 and the outlet end of the water tank 2 are in a mating state, the sealing element 8 may be located in the gap between the inlet end of the connecting pipe 4 and the outlet end of the water tank 2 to achieve a sealed connection between them.

[0090] For example, when the outlet of water tank 2 is a protruding insert pipe, the sealing element 8 can be installed first in the annular groove on the outer wall of the insert pipe. Then, align the inlet connecting sleeve of the connecting pipe 4 with the insert pipe of water tank 2, and slowly put the connecting sleeve onto the insert pipe. During insertion, the annular protrusion on the inner wall of the connecting sleeve will squeeze the sealing element 8, causing the sealing element 8 to undergo elastic deformation and fill the gap between the connecting sleeve and the insert pipe. When the connecting sleeve is completely fitted onto the insert pipe, the connecting pipe 4 and water tank 2 are fixed together by a simple snap-fit ​​structure or threaded connection to prevent accidental detachment. At this time, the sealing element 8, under compression, forms a reliable seal, ensuring that the water in water tank 2 will not leak.

[0091] For example, when the outlet of water tank 2 is a concave cavity, first place the sealing element 8 in the annular groove on the inner wall of the cavity. Next, align the inlet rod of the connecting pipe 4 with the cavity of water tank 2 and gently insert the rod into the cavity. During insertion, the annular protrusion on the outer wall of the rod will compress the sealing element 8, deforming it and filling the gap between the rod and the cavity. After insertion, use a snap-fit ​​or other fixing method to securely connect the two, achieving a sealed connection.

[0092] It should be noted that the sealing structure can be arranged in other ways besides the above-mentioned arrangement, and there are no restrictions on this.

[0093] In some embodiments, the seal 8 may include a sealing ring. The inlet end of the connecting pipe 4 is aligned with the outlet end of the water tank 2. The inlet end of the connecting pipe is inserted into the outlet end of the water tank 2. The sealing ring is fitted radially outward from the outlet end of the connecting pipe 4, and the outlet end of the water tank 2 is fitted radially outward from the sealing ring. In this embodiment, for example, when the connecting pipe 4 needs to be aligned with the water tank 2, the sealing ring can be fitted onto the connecting sleeve of the inlet end of the connecting pipe 4. Then, the inlet end of the connecting pipe 4 is aligned with the convex cylindrical interface of the water tank 2 and slowly inserted. During insertion, the interface of the water tank 2 gradually fits into the sealing ring. The sealing ring is compressed and undergoes elastic deformation, its inner diameter decreases, and it tightly fits against the outer wall of the connecting sleeve of the connecting pipe 4 and the inner wall of the interface of the water tank 2, filling the gap between them. When fully inserted, the sealing ring forms a reliable seal under double compression, ensuring that the water in the water tank 2 does not leak.

[0094] In some embodiments, the seal 8 may include a sealing ring. The inlet end of the connecting pipe 4 is aligned with the outlet end of the water tank 2, with the outlet end of the water tank 2 inserted into the inlet end of the connecting pipe. The sealing ring is fitted radially outward from the outlet end of the water tank 2, and the outlet end of the connecting pipe 4 is fitted radially outward from the sealing ring. In this embodiment, for example, when the connecting pipe 4 needs to be aligned with the water tank 2, the sealing ring is first fitted onto the outer wall of the outlet end of the concave cavity of the water tank 2. Then, the inlet end of the connecting pipe 4 is aligned with the cavity of the water tank 2 and gently inserted. During insertion, the insertion rod of the connecting pipe 4 gradually fits into the sealing ring, causing the sealing ring to deform under pressure, reducing its inner diameter and tightly fitting against the outer wall of the cavity of the water tank 2 and the inner wall of the insertion rod of the connecting pipe 4, filling the gap between them. After insertion, the water tank 2 and the connecting pipe 4 are fixed using the fixing structure of the housing 1, effectively sealing the water tank 2 and ensuring a leak-free water passage between the water tank 2 and the connecting pipe 4.

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

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

[0097] For example, when the electrical equipment is a fan evaporator, the evaporator assembly of the fan evaporator is connected to the water pump 3 via a water supply pipe 6, that is, the water supply pipe 6 is used to supply water to the evaporator assembly; the evaporator assembly and the water tank 2 can be connected to a drain pipe 7, that is, the drain pipe 7 is used to drain water from the evaporator assembly and transport the water discharged by the evaporator assembly to the water tank 2 to achieve water recycling.

[0098] It should be noted that when water flows into the water tank 2 from the drain pipe 7, without the anti-wave structure 9, the water flow directly impacts the water surface inside the tank 2, generating a significant impact force. The anti-wave structure 9 is partially located on the circumferential outer side of the drain pipe 7's outlet end, buffering the water flow as it exits the drain pipe 7. For example, the anti-wave structure 9 can be a sleeve with guide vanes. When the water flow impacts the guide vanes, its speed and direction are altered, and its energy is dispersed. This is similar to placing an obstacle in a river; the water flow impacts the obstacle, reducing the impact force and thus decreasing the waves formed inside the water tank 2. In some electrical equipment requiring high water level monitoring accuracy (such as evaporative coolers with level sensors), this wave reduction effect effectively prevents misjudgments of the water level caused by surface fluctuations.

[0099] Additionally, when the water flow is fast or the outlet of the drain pipe 7 is at a certain height above the water surface in the water tank 2, water can easily splash out. The anti-splash structure 9 acts as a barrier on the outer circumference, confining the splashing water inside the anti-splash structure 9. For example, the anti-splash structure 9 can include a barrier with a certain height and curvature, like a small dam. Even if the water flow tends to splash, it will be blocked by the barrier and fall back into the water tank 2, preventing water from overflowing and avoiding damage to electrical equipment or surrounding items due to water overflow. This function of preventing water overflow is particularly important for electrical equipment such as dehumidifiers that produce a large amount of condensate that quickly flows into the water tank 2.

[0100] The wave-damping structure 9 can be designed with spiral or inclined guide channels to guide water flow into the water tank 2 in a specific manner. When the water flows into the water tank 2 along these guide channels, its flow becomes more orderly. For example, a spiral guide channel allows the water to flow slowly into the water tank 2 in a spiral motion, gradually converting the kinetic energy of the water flow into potential energy, preventing the water flow from concentrating and impacting a single location, thus avoiding large waves. This orderly water flow helps maintain the stability of the water surface inside the water tank 2, ensuring normal water circulation within electrical equipment that requires a stable water supply environment (such as air purifiers with water circulation systems).

[0101] Additionally, some water tanks 2 may contain components such as sensors and filters. The anti-surge structure 9, which surrounds the outlet of the drain pipe 7, prevents water from directly impacting these components. For example, in a water tank 2 equipped with a water quality sensor, without the anti-surge structure 9, direct impact from the water flow could damage the sensor or affect its detection accuracy. The anti-surge structure 9 reduces this risk by buffering the water flow, extending the service life of internal components and improving the overall reliability of the electrical equipment.

[0102] The anti-wave structure 9 may include a connected snap-fit ​​part 92 and an anti-wave part 91. The snap-fit ​​part 92 and the anti-wave part 91 may be integrally formed or fixedly connected in other ways, which is not limited. The snap-fit ​​part 92 is snapped into the water inlet end of the water tank 2 to achieve a fixed assembly between the anti-wave structure 9 and the water tank 2. The anti-wave part 91 has a groove-shaped structure, and the water outlet end of the drain pipe 7 is located on the side of the groove opening of the groove-shaped structure and extends into the groove-shaped structure so that the anti-wave part 91 can better achieve the anti-wave effect.

[0103] When the electrical equipment generates water that needs to be discharged, the water pump 3 starts, drawing water from the source and transporting it through the drain pipe 7. After flowing out of the outlet of the drain pipe 7, the water directly enters the trough-shaped structure of the wave-damping structure 9. Due to the blocking and buffering effect of the trough-shaped structure, the impact force of the water flow is first weakened. Then, the water flows along the inner wall of the trough-shaped structure, thereby effectively reducing the waves generated when the water flow directly impacts the water surface of the water tank 2.

[0104] The bottom wall of the trough-shaped structure may include a drainage area 911, which may be the entire bottom wall or a part of the bottom wall, without limitation. The trough-shaped structure is provided with a water outlet 912. The drainage area 911 slopes downward from the direction away from the water outlet 912 to the direction closer to the water outlet 912, so as to more smoothly guide the water discharged from the drain pipe 7 to the water outlet 912 and discharge it into the water tank 2.

[0105] The drainage area 911 is equipped with multiple drainage ribs (not shown in the figure). The multiple drainage ribs are distributed and extend from the outlet 912 away to the outlet 912 closer to it, so as to better achieve the drainage effect.

[0106] In some implementations...

[0107] The anti-surge structure 9 includes a connected snap-fit ​​part 92 and an anti-surge part 91. The snap-fit ​​part 92 may include a slot, and the anti-surge structure 9 can be snapped into the slot of the snap-fit ​​part 92 through the upper edge of the water tank 2 to achieve a fixed assembly with the water tank 2. The anti-surge part 91 is constructed as a trough-shaped structure, which can be semi-cylindrical. The bottom wall of the trough-shaped structure includes a drainage area 911, which covers most of the bottom wall area, extending from one end of the trough-shaped structure to the other end, and occupies about two-thirds of the bottom wall area on the side near the outlet 912. Multiple drainage ribs are provided on the drainage area 911, and the drainage ribs have a triangular cross-section. The drainage ribs extend from away from the outlet 912 towards the outlet 912, and are distributed at an angle of 30 degrees to 60 degrees to each other. A circular outlet 912 is provided on the trough-shaped structure, located at the lowest point of the drainage area 911. The drainage area 911 is inclined downwards from the outlet 912 to the outlet 912, with an inclination angle of 10-15 degrees. This allows the water discharged from the drain pipe 7 to be more smoothly drained into the water tank 2 through the outlet 912.

[0108] When the electrical equipment is running, the water pump 3 delivers water through the drain pipe 7 to the trough-shaped structure of the anti-surge structure 9. The water flow is first blocked and buffered by the trough-shaped structure's perimeter, reducing the initial impact force. Then, the water diffuses within the trough-shaped structure and flows towards the drainage area 911. Since the drainage area 911 slopes downwards from the outlet 912 towards it, the water naturally flows towards the outlet 912 under gravity. Simultaneously, the drainage ribs further guide the water flow, dividing it into multiple smaller streams that converge orderly towards the outlet 912 along the direction of the drainage ribs. For example, in a dehumidifier, a large amount of condensate can quickly and smoothly enter the water tank 2 through the drainage system of the anti-surge structure 9, without forming large waves or splashing within the water tank 2. During the water circulation process of the cooling fan, water returning from the evaporator can also smoothly enter the water tank 2 through the anti-surge structure 9, ensuring a stable water level in the water tank 2 and facilitating the normal operation of the equipment.

[0109] It should be noted that the wave-breaking structure 9 can be any other structure besides the one described above, as long as it can achieve the wave-breaking effect. There are no restrictions on its specific structure.

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

[0111] The function of water tank 2 is to store water, and its basic property is to be a rigid body that is leak-proof. The relationship between water tank 2 and the connecting pipe 4 is a water-to-water connection. Water tank 2 can be fixedly assembled to the body housing 1 and can be removed from the body housing 1. Water tank 2 and connecting pipe 4 are respectively provided with a connecting sealing structure. The connecting sealing structure at the water outlet end of water tank 2 can be referred to as the first connecting sealing structure 41, and the connecting sealing structure at the water inlet end of connecting pipe 4 can be referred to as the second connecting sealing structure 21.

[0112] When the two sealing structures are not assembled, the water valves, under the action of springs, seal the corresponding water tank 2 and connecting pipe 4 respectively, ensuring that water tank 2 and connecting pipe 4 will not leak when the user removes water tank 2 to add water. When the sealing structures are assembled, the water valves on water tank 2 and connecting pipe 4 are opened, allowing the water passage between water tank 2 and connecting pipe 4 to be connected, and water from water tank 2 can flow into connecting pipe 4.

[0113] The function of connecting pipe 4 is to connect water tank 2 and water pump 3. Connecting pipe 4 is located at the bottom of the casing 1 and is a rigid, leak-proof structure. The relationship between connecting pipe 4 and water pump 3 is a sealed connection. The relationship between connecting pipe 4 and water tank 2 is a water connection. This water connection between connecting pipe 4 and water tank 2 is a key feature for concealing water pump 3 and its connected water pipes and wiring (e.g., electrical wiring). This design allows water pump 3 and most of connecting pipe 4 to be hidden inside the casing 1, with only the inlet end connecting to water tank 2 exposed. Compared to related technologies, this design allows for the concealment of water pump 3 and its connected water pipes and wiring (e.g., electrical wiring).

[0114] It should be noted that in this embodiment, the water pump 3, along with the connected water pipes and water pump 3 cables (e.g., electrical connection cables), are all concealed inside the casing 1. They do not need to be directly connected to the water tank 2. Only the interface of the casing 1 is exposed, enabling the crucial function of connecting the entire water circuit. In contrast, in related technologies, the water tank 2, which does not have the connecting pipe 4 in this embodiment, needs to be directly connected to the water pump 3. After removing the water tank 2, the water pump 3, along with the connected water pipes and water pump 3 cables (e.g., electrical connection cables), must be pulled out together, resulting in poor aesthetics and safety. Alternatively, the water tank 2 can be fixed to the casing 1, and the water pump 3 can also be concealed, but the water tank 2 cannot be removed for water replenishment, making water replenishment inconvenient.

[0115] In this embodiment, a spring force between the water valve and the water tank 2 / connecting pipe pushes the water valve towards the outlet of the sealed water tank 2 / inlet of the connecting pipe 4. After the water tank 2 and the connecting pipe 4 are connected, the water tank 2 is pressed down by gravity and fully engages with the connecting pipe 4, meaning that the outlet of the water tank 2 and the inlet of the connecting pipe 4 are coaxially inserted into each other. The weight of the water tank 2 is greater than the spring force, and the two water valves will push each other away after connection, achieving water connection. It should be noted that a sealing ring can be provided on the water tank 2 or the connecting pipe 4. The sealing ring can block the gap between the outlet of the water tank 2 and the inlet of the connecting pipe 4 after connection, achieving a sealing connection. Before connection, each of the two water valves seals its corresponding opening.

[0116] Additionally, a sealing pipe 10 can be installed between the water inlet of the water pump 3 and the outlet of the connecting pipe 4. The sealing pipe 10 can block the gap between the water inlet of the water pump 3 and the outlet of the connecting pipe 4 to prevent water leakage, while allowing water to flow between the two. Alternatively, the connecting pipe 4 itself can serve as the sealing pipe 10 to achieve a seal; this is not limited.

[0117] The function of the wave deflector is to divert back water. It is located on the upper part of the water tank 2 and is fixedly assembled with the water tank 2. The outlet of the drain pipe 7 is above the diversion area 911 of the wave deflector structure 9. The diversion area 911 reduces the backflow velocity of the returning water into the water tank 2, thereby reducing water flow impact noise.

[0118] It should be noted that the anti-surge structure 9 and the water tank 2 can be fixedly assembled via clips. The anti-surge structure 9 may include inner anti-surge ribs, assembly clips, and the structure corresponding to the aforementioned drainage area 911. At least a portion of the drainage area 911 may have an inclined angle greater than 5 degrees with respect to the horizontal plane. A gap for water passage is left between the drainage area 911 and the water tank 2 to form a water outlet 912. The minimum cross-section of the aforementioned gap must be larger than the cross-sectional area of ​​the water outlet 912 of the return water drain pipe 7 to avoid the accumulation of return water.

[0119] In this embodiment, after water is added to the water tank 2, it is installed onto the machine housing 1. After the water tank 2 is connected to the connecting pipe 4, the water passages of the water tank 2 and the connecting pipe 4 are automatically connected, and the water in the water tank 2 flows into the connecting pipe 4. During the installation of the water tank 2 into the machine housing 1, the inlet end of the connecting pipe 4 is inserted into the outlet end of the water tank 2, or the outlet end of the water tank 2 is inserted into the inlet end of the connecting pipe 4. During the installation process, two water valves are gradually pushed open. After installation, both water valves are opened, and the water from the tank 2 flows into the connecting pipe 4 from the connection point, completing the water connection and flow. A sealing ring can be provided between the outlet end of the water tank 2 and the inlet end of the connecting pipe 4 to prevent water overflow after connection.

[0120] After water pump 3 is started, it draws water from the corresponding pipe 4 and delivers it to the evaporator assembly via the water inlet pipe 6. Unevaporated return water flows from the drain pipe 7 onto the anti-surge structure 9, and is then guided through the diversion area 911 to the water tank 2, forming a complete water circuit with water pump 3. It should be noted that the diversion area 911 can be replaced with vertical diversion ribs or diversion columns; there are no limitations on this, as long as the diversion effect is achieved.

[0121] Most of the components, including the water pump 3 and its electrical connection, the water inlet pipe 6, the water outlet pipe 7, and the connecting pipe 4, are hidden inside the casing 1, rather than inside the water tank 2. After removing the water tank 2, users will only see the exposed part of the connecting pipe 4 that connects to the water tank 2, which reduces safety hazards, improves operational convenience, and greatly optimizes the overall appearance.

[0122] In this embodiment of the electrical equipment, the water pump 3 is no longer located inside the water tank 2, but is located inside the housing 1. The water pump 3 and the water tank 2 are connected by a connecting pipe 4. When water needs to be added to the water tank 2, the inlet end of the connecting pipe 4 is separated from the outlet end of the water tank 2, and then the water tank 2 can be removed to add water. The entire process does not require disassembling the water pump 3, and it does not expose the water pump 3 and its connecting pipes (such as water inlet pipes) and connecting wires (such as electrical connection wires), which is convenient to operate, improves aesthetics, and enhances the user experience.
