Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold fan, in particular to a humidifying device and cold fan. BACKGROUND

[0002] At present, as a common air cooling equipment, the cold fan is widely used in family, office and other environments.

[0003] The cold fan usually adopts a humidifying device to humidify the airflow, so as to realize the cooling and humidifying of the external environment. In order to ensure the cleanliness of the outlet air, a filter screen is usually arranged at the air inlet to block the dust and impurities in the air. However, the filter screen is easy to accumulate dust after being used for a period of time, which reduces the filtering efficiency and affects the air quality. At the same time, the user needs to regularly disassemble and clean the filter screen, which is complicated and inconvenient to use. SUMMARY

[0004] Therefore, it is necessary to provide a humidifying device and cold fan to solve the above problems.

[0005] A humidifying device is connected to the body of a cold fan, and the humidifying device comprises:

[0006] A wet curtain support is arranged on the airflow circulation path in the body and is arranged above the water tank of the cold fan along the height direction of the body; the windward surface of the wet curtain support is recessed to form a mounting groove;

[0007] A wet curtain is connected to the mounting groove;

[0008] A filter screen is connected to the mounting groove and is located on the windward side of the wet curtain;

[0009] A water guide is movably connected between the wet curtain support and the water tank;

[0010] The wet curtain support is provided with a first lower water outlet and a second lower water outlet which are both communicated with the mounting groove; the first lower water outlet and the water outlet at the bottom of the water tank are aligned with the wet curtain along the height direction; the second lower water outlet is aligned with the filter screen along the height direction;

[0011] The water guide is configured to have a first state and a second state; when the water guide is in the first state, the water guide is controlled to move to the water outlet path of the water outlet and guide the water flow from the water outlet to the second lower water outlet; when the water guide is in the second state, the water guide is controlled to move to the water outlet path away from the water outlet.

[0012] In one of the embodiments, a water blocking portion is formed on the wet curtain support, and the water blocking portion is located between the first drain and the second drain.

[0013] When the water guide is in the first state, the water guide is controlled to move to the water outlet path of the water outlet, and the water flow from the water outlet is guided to the side of the water blocking portion close to the second drain.

[0014] In one of the embodiments, the water blocking portion forms a water blocking groove facing the water tank opening, and the height of at least part of the groove side wall close to the second drain is lower than the height of the remaining groove side wall.

[0015] When the water guide is in the first state, the water guide is controlled to move to the water outlet path of the water outlet, and the water flow from the water outlet is guided into the water blocking groove.

[0016] In one of the embodiments, the groove side wall of the water blocking groove close to the second drain is defined as a drain groove wall, and the end of the drain groove wall close to the groove opening of the water blocking groove is configured as a wavy structure.

[0017] In one of the embodiments, the water guide is configured as a plate structure, the surface of the wet curtain support close to the water tank is protruded to form a mounting portion, and the water guide is rotatably connected to the mounting portion.

[0018] When the water guide is in the first state, the water guide is controlled to rotate to the water outlet path of the water outlet, and the end of the water guide close to the second drain is downwardly inclined; when the water guide is in the second state, the water guide is controlled to rotate to be perpendicular to the height direction, so as to avoid the water outlet path of the water outlet.

[0019] In one of the embodiments, one side surface of the water guide is recessed to form a water guide groove, and a drain opening is formed on one groove side wall of the water guide groove.

[0020] When the water guide is in the first state, the water guide is controlled to rotate to the groove opening of the water guide groove, and the end of the water guide close to the second drain is downwardly inclined.

[0021] In one of the embodiments, a rotating shaft is further included, one end of the rotating shaft is rotatably connected to the mounting portion, and the other end of the rotating shaft is fixedly connected to the water guide.

[0022] In one of the embodiments, a driving member is further included, which is coupled to the mounting portion and drivingly connected to the rotating shaft.

[0023] A cooling fan includes a humidifying device as in the foregoing embodiments.

[0024] In one of the embodiments, a body and a water tank are further included, the body has a mounting cavity formed therein, and the humidifying device and the water tank are coupled to the mounting cavity; the water tank is disposed above the wet curtain support in a height direction of the body, and a water outlet is formed on a bottom side of the water tank; a waste water tank is disposed below the wet curtain support in the height direction of the body, and a water inlet is formed on the waste water tank; a waste water outlet is formed on a side of the wet curtain support close to the waste water tank and is in communication with the mounting slot, and the waste water outlet is in communication with the water inlet.

[0025] The humidifying device and the cooling fan, the humidifying device includes a wet curtain support, a wet curtain, a filter screen and a water guide. The wet curtain support is disposed on a flow path of air flow in the body and is disposed below a water tank of the cooling fan in a height direction of the body. A windward surface of the wet curtain support is recessed to form a mounting slot in a flow direction of the air flow. The wet curtain is coupled to the mounting slot. The filter screen is coupled to the mounting slot and is located on a windward side of the wet curtain. The water guide is movably coupled between the wet curtain support and the water tank.

[0026] It can be understood that, in the operation process of the cooling fan, external air is accelerated to high-speed airflow under the action of the fan and is blown to the humidifying device, so as to filter the high-speed airflow by the filter screen and humidify the high-speed airflow by the wet curtain, and then discharge the filtered and humidified high-speed airflow to the outside to cool and humidify the external environment.

[0027] Specifically, the high-speed airflow flowing through the humidifying device first passes through the filter screen, and dust, hair and other large-particle impurities in the high-speed airflow are intercepted and filtered by the filter screen, thereby effectively avoiding that the impurities in the high-speed airflow directly adhere to the surface of the wet curtain to affect the humidifying effect and the service life of the wet curtain.

[0028] Subsequently, the high-speed airflow filtered by the filter screen flows through the wet curtain, and the water in the water tank flows out through the water outlet and is guided to the wet curtain by the water guide, so that the wet curtain as a whole remains wet. In this way, the high-speed airflow contacts the wet curtain and carries the moisture in the wet curtain, and forms a humid airflow.

[0029] Finally, the humid airflow is blown to the outside through the air outlet of the cooling fan to cool and humidify the external environment.

[0030] Further, the wet curtain support is provided with a water storage groove on the side facing the water tank, the bottom of the water storage groove is provided with a first water outlet and a second water outlet, the first water outlet and the second water outlet are both in communication with the mounting groove; the first water outlet is aligned with the wet curtain in the height direction; the second water outlet is aligned with the filter screen in the height direction; the bottom of the water tank is provided with a water outlet, and the water outlet faces the water storage groove. The water guide member is configured to have a first state and a second state. When the water guide member is in the first state, the water guide member is controlled to move to the water outlet path of the water outlet, and the water flow from the water outlet is guided to the second water outlet. When the water guide member is in the second state, the water guide member is controlled to move to the water outlet path away from the water outlet, so that the water flow from the water outlet is guided to the first water outlet.

[0031] It can be understood that during the operation of the cold fan, when it is necessary to humidify the external environment, the water guide member needs to be controlled to move to the water outlet path away from the water outlet, that is, to make the water guide member in the second state. At this time, the water in the water tank flows out of the water outlet and can directly enter the wet curtain in the mounting groove through the first water outlet, so that the wet curtain remains wet to realize the humidification function of the high-speed airflow.

[0032] Correspondingly, when it is necessary to clean the filter screen, the water guide member needs to be controlled to move to the water outlet path of the water outlet, that is, to make the water guide member in the first state. At this time, the water in the water tank flows out of the water outlet and is received and guided by the water guide member to the second water outlet. Since the second water outlet is aligned with the filter screen in the height direction, the water flow can directly flow to the filter screen through the second water outlet, so as to flush the dust, hair and other large particle impurities accumulated on the windward surface of the filter screen, so as to use the water flow to carry away the impurities attached to the surface of the filter screen, realize the automatic cleaning of the filter screen, and do not need the user to manually disassemble the filter screen for cleaning, effectively simplifying the operation steps of the user and improving the use convenience.

[0056] Currently, air coolers are widely used in homes, offices, and other environments as common air cooling devices.

[0057] Air coolers typically use humidifiers to humidify the airflow, thereby cooling and humidifying the external environment. Before the airflow passes through the humidifier, a filter is usually installed at the air inlet to block dust and impurities from the air and ensure the cleanliness of the outlet air. However, after a period of use, dust easily accumulates on the filter, leading to a decrease in filtration efficiency and affecting air quality. Furthermore, users need to regularly disassemble and clean the filter, which is cumbersome and inconvenient.

[0058] Therefore, to resolve the above issues, please refer to [link / reference needed]. Figures 1 to 4 This application provides a cooling fan 200 in one or more embodiments, which includes a body 20, a water tank 21, a fan, and a humidifying device 100. An installation cavity 201 is formed within the body 20, and the humidifying device 100, water tank 21, and fan are all connected within the installation cavity 201. The humidifying device 100 is located on the air outlet side of the fan, and the water tank 21 is spaced apart above the evaporative cooling pad bracket 10 along the height direction of the body 20, with a water outlet 211 on the bottom side of the water tank 21.

[0059] Understandably, please see Figures 1 to 9 The humidification device 100 provided in this embodiment of the application has a water guide 13 between the water tank 21 and the wet curtain bracket 10. By switching the different states of the water guide 13, the water flowing out of the water tank 21 has two flow paths that can respectively guide the water flow to the wet curtain 11 or the filter screen 12, thereby realizing the humidification function of the wet curtain 11 or the cleaning function of the filter screen 12. This satisfies the user's need for cooling and humidifying the external environment or the user's need for convenient cleaning of the filter screen 12, and helps to ensure the cleanliness of the air output of the cool fan 200 and the stability of the humidification function.

[0060] Specifically, please see Figure 2 , Figure 3 , Figure 6 and Figure 7 The humidifier 100 includes a wet curtain support 10, a wet curtain 11, a filter 12, and a water guide 13. The wet curtain support 10 is positioned within the airflow path of the unit 20 and is spaced apart below the water tank 21 of the evaporator 200 along the height of the unit 20. The windward side of the wet curtain support 10 has a recessed mounting groove 101 formed along the airflow direction. The wet curtain 11 is fitted into the mounting groove 101. The filter 12 is fitted into the mounting groove 101 and located on the windward side of the wet curtain 11. The water guide 13 is movably fitted between the wet curtain support 10 and the water tank 21.

[0061] Understandably, during the operation of the air cooler 200, the outside air is accelerated into a high-speed airflow by the fan and blown towards the humidifier 100. The high-speed airflow is filtered by the filter 12 and humidified by the wet curtain 11. The filtered and humidified high-speed airflow is then discharged to the outside to cool and humidify the outside environment.

[0062] Specifically, the high-speed airflow passing through the humidification device 100 will first pass through the filter screen 12, and larger particles such as dust and hair in the high-speed airflow will be intercepted and filtered by the filter screen 12, thereby effectively preventing impurities in the high-speed airflow from directly adhering to the surface of the wet curtain 11 and affecting the humidification effect and the life of the wet curtain 11.

[0063] Subsequently, the high-speed airflow filtered by the filter screen 12 flows through the wet curtain 11. The water in the water tank 21 flows out through the outlet 211 and is guided onto the wet curtain 11 by the water guide 13, so that the wet curtain 11 remains moist. In this way, when the high-speed airflow comes into contact with the wet curtain 11, it will carry the moisture in the wet curtain 11 and form a humid airflow.

[0064] Finally, the humid airflow will be blown outward through the air outlet of the air cooler 200 to cool and humidify the external environment.

[0065] Further, please see Figure 2 and Figure 3 The evaporative cooling pad bracket 10 has a water storage tank facing the water tank 21. The bottom of the water storage tank has a first drain outlet 102 and a second drain outlet 103, both of which are connected to the mounting groove 101. The first drain outlet 102 is aligned vertically with the evaporative cooling pad 11, and the second drain outlet 103 is aligned vertically with the filter screen 12. The bottom of the water tank 21 has a water outlet 211, which faces the water storage tank. The water guide 13 is configured to have a first state and a second state. When the water guide 13 is in the first state, it is controlled to move onto the water outlet path of the outlet 211 and guides the water flowing from the outlet 211 to the second drain outlet 103. When the water guide 13 is in the second state, the water guide 13 is controlled to move to the water outlet path of the avoidance outlet 211, so that the water flowing out of the outlet 211 is directed to the first drain 102.

[0066] Understandably, during the operation of the 200 air cooler, please refer to [the relevant documentation / reference]. Figure 2 When humidification of the external environment is required, the water guide 13 needs to be moved to the water outlet path of the water outlet 211, so that the water guide 13 is in the second state. At this time, the water in the water tank 21 flows out of the water outlet 211 and can enter the wet curtain 11 in the mounting groove 101 through the first drain 102, so as to keep the wet curtain 11 moist and realize the humidification function of the high-speed airflow.

[0067] Correspondingly, please see Figure 3 When the filter screen 12 needs to be cleaned, the water guide 13 needs to be moved to the water outlet path of the outlet 211, so that the water guide 13 is in the first state. At this time, the water in the water tank 21 flows out of the outlet 211 and is received by the water guide 13 and guided to the second drain 103. Since the second drain 103 is aligned with the filter screen 12 in the height direction, the water can flow directly to the filter screen 12 through the second drain 103, thereby washing away larger particles of impurities such as dust and hair accumulated on the windward side of the filter screen 12. The water flow carries away the impurities attached to the surface of the filter screen 12, realizing automatic cleaning of the filter screen 12 without the need for the user to manually disassemble the filter screen 12 for cleaning, effectively simplifying the user's operation steps and improving the convenience of use.

[0068] In some embodiments, see Figure 2 , Figure 3 and Figure 8 The water storage tank is equipped with a water-blocking part 104, which divides the water storage tank into a first water storage section and a second water storage section. A first drain outlet 102 is located in the first water storage section, and a second drain outlet 103 is located in the second water storage section. A water guide 13 is positioned above the water-blocking part 104. When the water guide 13 is in its first state, the water outlet 211 is connected to the second water storage section. When the water guide 13 is in its second state, the water outlet 211 is connected to the first water storage section.

[0069] Understandably, during the operation of the air cooler 200, when it is necessary to clean the filter screen 12, the water guide 13 needs to be controlled in the first state to direct the water flow to the second water storage section, and then flow into the installation groove 101 through the second drain 103 to clean the filter screen 12. The water blocking part 104 can block the water flow to the first drain 102, thereby ensuring that the water flow can be concentrated to the second drain 103, so as to ensure that there is enough water to rinse the filter screen 12, and to improve the cleaning effect and cleaning efficiency of the filter screen 12.

[0070] Further, please see Figure 2 , Figure 3 and Figure 8 The second water storage section is provided with a drainage channel wall 106. The water-blocking section 104, the drainage channel wall 106, and the channel wall of the second water storage section together form a water-blocking channel 105. At least part of the drainage channel wall 106 is lower in height than the channel walls of the remaining water-blocking channels 105. When the water guide 13 is in the first state, the water guide 13 is controlled to move to the water outlet path of the outlet 211 and guides the water flowing out of the outlet 211 into the water-blocking channel 105.

[0071] Understandably, during the operation of the air cooler 200, when cleaning the filter 12 is required, the water guide 13 needs to be controlled in the first state to guide the water flow into the baffle 105. Since the height of the side wall of the baffle 105 near the second drain 103 is low, the water flow will accumulate in the baffle 105. When the water level in the baffle 105 exceeds the height of at least the side wall of the baffle 105 near the second drain 103, the water will overflow along the side wall to the second drain 103, effectively preventing the water from splashing during the guiding process and ensuring that the water flow is concentrated and flows stably to the filter 12.

[0072] Furthermore, please see Figure 2 , Figure 3 and Figure 8 The end of the drainage channel wall 106 facing the water tank 21 is constructed as a wave-shaped structure.

[0073] Understandably, the wavy structure increases the contact area between the top of the drainage channel wall 106 and the water flow, allowing the water to overflow evenly along the length of the drainage channel wall 106 during overflow. This ensures that the overflowing water fully covers the filter screen 12, preventing areas from being missed or insufficiently cleaned, thus effectively improving the cleaning effect on the filter screen 12. Simultaneously, the wavy structure also slows down the water flow velocity to a certain extent, allowing for more sufficient contact time between the water and the surface of the filter screen 12, enhancing the rinsing effect.

[0074] In some embodiments, see Figure 2 , Figure 3 and Figure 9 The water guide 13 is constructed as a plate-like structure, and a water guiding surface is formed on the water guide 13. A mounting portion 107 protrudes from the surface of the wet curtain bracket 10 near the water tank 21, and the water guide 13 is rotatably fitted onto the mounting portion 107. When the water guide 13 is in the first state, it is controlled to rotate to the water outlet path of the outlet 211, with the water guiding surface facing the outlet 211, and the end of the water guiding surface near the second drain 103 inclined downwards. When the water guide 13 is in the first state, it is controlled to rotate until the water guiding surface is parallel to the height direction, thus avoiding obstructing the water outlet path of the outlet 211.

[0075] Understandably, during the operation of the air cooler 200, when cleaning the filter 12 is required, the water guide 13 needs to be rotated around the mounting part 107 to be located directly below the water outlet 211 of the water tank 21, and the end of the water guide 13 near the second drain 103 should be tilted downwards, so that the water guide 13 is in the first state. In this way, the water flowing out of the water outlet 211 of the water tank 21 can flow smoothly to the water baffle 105 under the positioning and tilting guidance of the water guide 13.

[0076] Correspondingly, when humidification of the external environment is required, the water guide 13 needs to be controlled to rotate upward or away from the outlet 211 around the mounting part 107, so that the water guide 13 can avoid the water outlet path of the outlet 211, thus ensuring that the water guide 13 is in the second state. In this way, it can be ensured that the water flow can flow directly to the wet curtain 11 through the first drain 102 without obstruction.

[0077] In some embodiments, see Figure 2 , Figure 3 and Figure 9 The water guide component 13 has a recessed sidewall facing away from the water tank 21, forming a water guide groove 131. A drain outlet 132 is located at the end of the water guide component 13 near the second drain outlet 103, and the water guide groove 131 communicates with the drain outlet 132. When the water guide component 13 is in the first state, it is controlled to rotate until the opening of the water guide groove 131 is located on the water outlet path of the water outlet 211, with the water guide groove 131 facing the water outlet 211. The end of the water guide component 13 with the drain outlet 132 is close to the second drain outlet 103 and is inclined downwards.

[0078] Understandably, during the operation of the air cooler 200, when the filter 12 needs cleaning, the water guide component 13 is in its first state. At this time, the opening of the water guide channel 131 is directly opposite the outlet 211 of the water tank 21. The water flowing out of the outlet 211 can fall directly into the water guide channel 131. The water guide channel 131 can collect and initially guide the water flow, preventing the water from flowing randomly or splashing on the surface of the water guide component 13. Furthermore, since the water guide component 13 is in its first state, the end of the water guide component 13 near the second drain 103 is inclined downwards, and the side wall of the water guide channel 131 near the second drain 103 has a drain outlet 132. The water flowing into the water guide channel 131 will flow along the inclined direction of the water guide channel 131 under its own gravity and will eventually be discharged through the drain outlet 132.

[0079] In other words, the water guide channel 131 can slow down the flow rate of water and avoid splashing caused by excessive or rapid water flow from the outlet 211. The drain outlet 132 can ensure the directional flow of water, so that the water discharged from the water guide 13 can flow accurately to the water baffle 105 or the second drain outlet 103, thereby ensuring the rinsing effect on the filter screen 12.

[0080] In some embodiments, see Figure 6 , Figure 7 and Figure 9 The humidification device 100 also includes a rotating shaft 14, one end of which is rotatably connected to the mounting part 107, and the other end is fixedly connected to the water guide 13.

[0081] Understandably, the simple structure of the rotating shaft 14, which enables the water guide 13 to rotate, provides stable support for the rotation of the water guide 13, allowing the water guide 13 to smoothly switch between the first and second states around the rotating shaft 14. This effectively ensures the switching accuracy and stability of the water guide 13 during long-term use, thereby improving the overall reliability and service life of the cooling fan 200.

[0082] It should be noted that the rotating shaft can be driven manually or automatically.

[0083] Understandably, if the shaft is manually driven, the user can directly switch the water guide 13 between the first and second states by rotating the shaft 14 or the handle connected to the shaft 14. This method is simple in structure, low in cost, and suitable for scenarios where the requirements for ease of operation are not extremely high.

[0084] If the rotating shaft adopts an automatic drive method, the humidifier 100 may further include a drive component, such as a motor. By controlling the start and stop of the drive component, the rotating shaft 14 can be driven to rotate automatically, thereby realizing the automatic switching of the state of the water guide component 13. The automatic drive method can improve the convenience of user operation.

[0085] In some embodiments, see Figure 6 , Figure 7 and Figure 9 The humidifier 100 also includes a drive component 15, which is fitted onto the mounting portion 107 and is drivenly connected to the rotating shaft 14.

[0086] Understandably, the drive unit 15 can provide power for the rotation of the water guide 13, enabling the water guide 13 to automatically switch between the first and second states without manual operation by the user, thereby effectively improving the convenience and intelligence of the cool fan 200.

[0087] In some embodiments, the evaporative cooling pad device 100 further includes a wastewater tank, which is disposed below the evaporative cooling pad support along the height direction of the device body, and the wastewater tank has a water inlet; the evaporative cooling pad support has a wastewater inlet communicating with the mounting groove on the side near the wastewater tank, and the wastewater inlet is connected to the water inlet.

[0088] Understandably, excess water from the outlet 211 of the water tank 21, generated after wetting the evaporative cooling pad, or wastewater from cleaning the filter, will flow out through the wastewater outlet on the evaporative cooling pad bracket and into the wastewater tank through the inlet for collection. This effectively prevents wastewater from dripping directly into the air cooler's interior or external environment, keeping the inside of the unit dry and clean, and maintaining a hygienic operating environment. It also facilitates regular cleaning and emptying of the wastewater tank, improving the convenience and user experience of the air cooler.

[0089] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
