Description

Technical Field

[0001] This invention relates to the field of air treatment technology, and more specifically to an air outlet device. Background Technology

[0002] The basic working principle of a fan evaporator is that a water pump draws water from a tank to an evaporator (wet curtain). The water evaporates and absorbs heat on the evaporator (wet curtain), and the heat of the air blowing across the evaporator (wet curtain) is absorbed, making the air blown out by the fan cooler and thus humidifying and cooling the indoor air. Air purifiers, on the other hand, use their internal filter layers to filter dust and formaldehyde and other impurities from the air, improving indoor air cleanliness.

[0003] Currently, air coolers typically only have a humidifying function and cannot filter the air. Adding a filter would increase the size of the air cooler, making the model bulky. Summary of the Invention

[0004] In view of this, the present invention provides an air outlet device to solve the problem that the existing air cooler only has a humidification function and cannot filter the air, while adding a filter will increase the size of the air cooler and make it bulky.

[0005] The first aspect of the present invention provides an air outlet device, including a base, a housing, a bracket, a wet curtain, and a filter structure. The housing is disposed on the base and has a communicating air inlet and an air outlet. The bracket is connected to the base and is disposed corresponding to the air inlet. The bracket has a first use state and a second use state. When the bracket is in the first use state, the wet curtain is disposed on the bracket, and the air entering from the air inlet flows through the wet curtain for humidification and cooling before flowing out through the air outlet. When the bracket is in the second use state, the filter structure is disposed on the bracket, and the air entering from the air inlet flows through the filter structure for purification before flowing out through the air outlet.

[0006] Beneficial Effects: The bracket has a first usage state and a second usage state. When the air outlet device needs to perform humidification, the bracket is in the first usage state. At this time, the evaporative cooling pad is installed on the bracket, and the air entering from the air inlet flows through the evaporative cooling pad and is humidified and cooled. The humidified and cooled air then flows out through the air outlet. When the air outlet device needs to perform purification, the bracket is in the second usage state. At this time, the filter structure is installed on the bracket, and the air entering from the air inlet flows through the filter structure and is purified. The purified air then flows out through the air outlet. This application, by setting the bracket to have a first usage state and a second usage state, and correspondingly installing the evaporative cooling pad or the filter structure on the bracket in different usage states, enables the air outlet device to perform both humidification and filtration functions. It also avoids the problem of large overall size and bulky model caused by simultaneously installing the evaporative cooling pad and the filter structure on the bracket, thus ensuring sufficient air outlet space within the air outlet device.

[0007] In one optional embodiment, the air outlet device further includes a water circuit assembly connected to the evaporative cooling pad. When the bracket is in the first use state, the water circuit assembly is turned on to provide saturating liquid to the evaporative cooling pad, and when the bracket is in the second use state, the water circuit assembly is turned off.

[0008] Beneficial effects: The water circuit component is used to provide humidifying liquid to the wet curtain when the bracket is in the first use state, so as to keep the wet curtain moist and ensure the humidification effect of the air. When the bracket is in the second use state, the water circuit component is turned off to ensure the normal use of the filter structure.

[0009] In one optional embodiment, the air outlet device further includes a control component coupled to the water circuit component, wherein when the bracket is in the second use state, the control component controls the water circuit component to shut down.

[0010] Beneficial effects: Further design of the control component, coupled with the water circuit component, allows the water circuit component to be shut down automatically when the support is in its second use state, thereby improving control efficiency.

[0011] In one optional embodiment, the control component includes a proximity switch and a magnetic element. The proximity switch is disposed on the bracket and coupled to the water circuit assembly. The magnetic element is disposed on the filter structure. When the bracket is in the second use state, the magnetic element corresponds to the proximity switch to trigger the proximity switch to control the water circuit assembly to close.

[0012] Beneficial effects: When the bracket is in the second use state, the filter structure is set on the bracket, and the magnetic component on the filter structure corresponds to the proximity switch, thereby triggering the proximity switch to control the water circuit assembly to shut down, preventing the wetting liquid in the water circuit assembly from wetting the filter structure and ensuring the normal use function of the filter structure.

[0013] In one alternative embodiment, the bracket includes a support body adapted to mount the wet curtain or the filter structure, the support body having a groove on its edge, and the proximity switch disposed within the groove.

[0014] Beneficial effects: The support body is used to support and fix the wet curtain or filter structure. The tank is set along the edge of the support body to avoid the installation of the wet curtain or filter structure. The tank can position the installation of the proximity switch and improve the installation stability.

[0015] In one optional embodiment, the water circuit assembly includes a water tank, a water pump, and a water outlet pipe. The water tank is disposed on the base, the water pump is disposed in the water tank, the water pump is coupled to the proximity switch, one end of the water outlet pipe is connected to the water pump, and the other end of the water outlet pipe provides the immersion liquid to the wet curtain.

[0016] Beneficial effects: The water tank is used to store the soaking liquid. The water pump can deliver the soaking liquid in the water tank to the outlet pipe. The soaking liquid then flows out to the wet curtain through the outlet pipe to keep the wet curtain moist. The water pump is coupled with a proximity switch. When the bracket is in the second use state, the water pump can be turned off by controlling the proximity switch.

[0017] In one optional embodiment, the support is further provided with a liquid distribution mechanism, which includes a water inlet and a liquid distribution hole. The water inlet is connected to the water outlet pipe, and the liquid distribution hole is distributed along the upper edge of the support. The liquid distribution hole is connected to the water inlet.

[0018] Beneficial effects: By distributing the liquid distribution holes along the upper edge of the bracket, when the bracket is in use, the soaking liquid in the water tank flows into the water outlet pipe through the water pump, and then flows from the water outlet pipe to the water inlet, and then from the water inlet to the liquid distribution holes. The liquid distribution holes are evenly distributed downwards along the upper edge of the bracket onto the wet curtain, so as to evenly wet the wet curtain.

[0019] In one optional embodiment, the lower edge of the bracket is also provided with a return water inlet, and the water circuit assembly further includes a return water pipe, one end of which is connected to the return water inlet, and the other end of which is connected to the water tank.

[0020] Beneficial effects: By further setting a return water inlet at the lower edge of the support, when excess soaking liquid on the wet curtain seeps out and flows to the lower edge of the support, it can flow into the return water pipe through the return water inlet and then back to the water tank through the return water pipe, realizing the recycling of the soaking liquid and preventing the soaking liquid from flowing to the outside and causing pollution.

[0021] In one optional embodiment, the cover is an annular structure with openings at both ends forming the air inlets, and the air outlet is disposed on the annular surface of the cover, with the air outlet direction perpendicular to the air inlet direction.

[0022] Beneficial effects: By setting the casing to a ring structure and forming air inlets at both ends, air can enter the casing through the air inlets at both ends and be blown out through the air outlets on the ring surface of the casing, thus realizing air intake and exhaust.

[0023] In one optional embodiment, the air outlet device further includes a support frame, which is disposed opposite to the air inlets at both ends of the housing. The support frame is fixedly connected to the base, and the bracket is provided on the support frame.

[0024] Beneficial effects: The set support frame can fix the bracket. The bracket is fixedly connected to the machine base and then placed on the support frame, so that the force on the bracket is transferred to the machine base through the support frame, thus achieving force support.

[0025] In one optional embodiment, the air outlet device further includes an air supply component rotatably disposed within the housing, the air supply component being used to draw air from the air inlet into the housing and deliver it to the air outlet.

[0026] Beneficial effects: Further, by setting up an air supply component, the rotation of the air supply component can draw air from the air inlet into the casing and send it out to the air outlet, realizing the dynamic circulation of air.

[0027] In one optional embodiment, the air supply assembly includes a centrifugal impeller and an air supply motor. The centrifugal impeller is rotatably disposed within the housing, and centrifugal blades are arranged circumferentially on the centrifugal impeller. The output shaft of the air supply motor is fixedly connected to the center of the centrifugal impeller to drive the centrifugal impeller to rotate.

[0028] Beneficial effects: The blower motor drives the centrifugal impeller to rotate inside the casing, creating a negative pressure inside the casing. Under the action of negative pressure, air flows into the casing from the air inlet and flows to the centrifugal fan blades through the centrifugal action of the impeller, and is then delivered to the air outlet through the centrifugal fan blades.

[0029] In one optional embodiment, the air outlet device further includes a guide air duct disposed inside the housing. The guide air duct covers the outer periphery of the centrifugal impeller. The guide air duct has a guide inlet and a guide outlet. The guide inlet and the air inlet are connected to each other, and the guide outlet and the air outlet are connected to each other.

[0030] Beneficial effects: By further setting up the airflow guide duct and covering the outer periphery of the centrifugal impeller, when the centrifugal impeller rotates, the air enters the centrifugal impeller along the air inlet and the airflow guide inlet, and flows to the airflow guide outlet through the centrifugal action of the centrifugal impeller, and finally flows out through the air outlet. It can be seen that the airflow guide duct can guide the flowing air, so that the air drawn in from the air inlet can be guided by the airflow guide duct and flow out through the airflow guide outlet to the air outlet, avoiding airflow turbulence and reducing airflow noise.

[0031] In one optional embodiment, the air duct and the housing are fixedly connected, and the air outlet device further includes an air outlet adjustment component connected to the air duct, which is used to drive the air duct and the housing to rotate together to adjust the position of the air outlet on the housing.

[0032] Beneficial effects: By fixing the air duct and the housing in place, the air duct can be rotated by the air outlet adjustment component, which in turn drives the housing to rotate as well. This allows the air outlet on the housing to rotate circumferentially, thereby adjusting the air outlet position to meet diverse air outlet needs.

[0033] In one optional embodiment, the air outlet adjustment assembly includes an adjustment motor, which is connected to the support frame at one end of the housing, and the output shaft of the adjustment motor is fixedly connected to the center of the air guide duct.

[0034] Beneficial effects: The regulating motor is connected to the support frame at one end of the cover, the air duct is connected to the output shaft of the regulating motor, and the cover is connected to the air duct. Therefore, the cover, the air duct and the regulating motor can all be supported by the support frame at one end of the cover. The regulating motor drives the air duct to rotate, thereby driving the cover to rotate synchronously.

[0035] In one optional embodiment, the airflow duct includes a first air duct and a second air duct. The first air duct is correspondingly arranged with the air inlet at one end of the cover. The first air duct is provided with a first mounting bracket. The output shaft of the regulating motor is connected to the first mounting bracket through a first bushing. The second air duct is connected to the first air duct. At least one of the first air duct and the second air duct is connected to the cover. The second air duct is correspondingly arranged with the air inlet at the other end of the cover. The centrifugal impeller is arranged between the second air duct and the first air duct. The second air duct is provided with a second mounting bracket. The blower motor is arranged on the second mounting bracket. The second mounting bracket is rotatably connected to the support frame at the other end of the cover.

[0036] Beneficial effects: By setting the airflow duct into the form of a first air duct and a second air duct, with the first and second air ducts respectively corresponding to the air inlets on both sides of the cover, the air entering from both air inlets is guided. The output shaft of the regulating motor is connected to the first mounting bracket through the first bushing, thereby realizing the connection between the regulating motor and the first air duct. The blower motor is mounted on the second air duct through the second mounting bracket, and the second air duct is rotatably fitted to the support bracket at the other end of the cover through the second mounting bracket to achieve force support. When the regulating motor drives the first air duct to rotate, it drives the second air duct, the blower motor and the cover to rotate synchronously. At the same time, the second air duct rotates relative to the support bracket at the other end of the cover through the second mounting bracket. Attached Figure Description

[0064] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] The following is combined with Figures 1 to 12 The following describes embodiments of the present invention.

[0066] According to embodiments of the present invention, such as Figures 1 to 3 , Figure 6 and Figure 7 As shown, an air outlet device is provided, including a base 1, a housing 2, a bracket 3, an evaporative cooling pad 4, and a filter structure 5. The housing 2 is disposed on the base 1 and has a connected air inlet 21 and an air outlet 22. The bracket 3 is connected to the base 1 and is disposed corresponding to the air inlet 21. The bracket 3 has a first use state and a second use state. When the bracket 3 is in the first use state, the evaporative cooling pad 4 is disposed on the bracket 3. The air entering from the air inlet 21 flows through the evaporative cooling pad 4, is humidified and cooled, and then flows out through the air outlet 22. When the bracket 3 is in the second use state, the filter structure 5 is disposed on the bracket 3. The air entering from the air inlet 21 flows through the filter structure 5, is purified, and then flows out through the air outlet 22.

[0067] In this embodiment, the air outlet device has a bracket 3 with a first usage state and a second usage state. When the air outlet device needs to perform humidification, the bracket 3 is in the first usage state. At this time, the evaporative cooling pad 4 is installed on the bracket 3. The air entering from the air inlet 21 flows through the evaporative cooling pad 4 and is humidified and cooled. The humidified and cooled air then flows out through the air outlet 22. When the air outlet device needs to perform purification, the bracket 3 is in the second usage state. At this time, the filter structure 5 is installed on the bracket 3. The air entering from the air inlet 21 flows through the filter structure 5 and is purified. The purified air then flows out through the air outlet 22. This application sets the bracket 3 with a first usage state and a second usage state, and installs the evaporative cooling pad 4 or the filter structure 5 on the bracket 3 in different usage states, so that the air outlet device can perform both humidification and filtration functions. This avoids the problem of large overall size and bulky model caused by simultaneously installing the evaporative cooling pad 4 and the filter structure 5 on the bracket 3, and ensures the air outlet space within the air outlet device.

[0068] The base 1 serves to support and fix the entire machine. In this embodiment, the base 1 includes a vertical support 11 and a chassis 12. The top of the vertical support 11 is connected to the cover 2 and the bracket 3, and the bottom of the vertical support 11 is fixedly connected to the chassis 12. The chassis 12 provides support for the vertical support 11.

[0069] like Figure 3 and Figure 4 As shown, the cover 2 has an annular structure, with openings at both ends forming air inlets 21 and air outlets 22 disposed on the annular surface of the cover 2. The air outlet direction of the air outlet 22 is perpendicular to the air inlet direction of the air inlet 21.

[0070] By setting the casing 2 as an annular structure and forming air inlets 21 at both ends, air can enter the casing 2 through the air inlets 21 at both ends and be blown out through the air outlets 22 on the annular surface of the casing 2, thus realizing air intake and exhaust.

[0071] Correspondingly, each air inlet 21 is equipped with a bracket 3, which can switch between the first and second use states to humidify or filter and purify the air.

[0072] In this embodiment, the wet curtain 4 and the bracket 3, as well as the filter structure 5 and the bracket 3, are detachably connected. When the bracket 3 needs to be changed from the first use state to the second use state, the wet curtain 4 is first removed from the bracket 3, and then the filter structure 5 is installed on the bracket 3. When the bracket 3 needs to be changed from the second use state to the first use state, the filter structure 5 is first removed from the bracket 3, and then the wet curtain 4 is installed on the bracket 3.

[0073] like Figures 5 to 8As shown, the bracket 3 can support and fix the evaporative cooling pad 4 and the filter structure 5. The bracket 3 has a rectangular frame structure, and a rectangular mounting cavity is formed inside for mounting the evaporative cooling pad 4 or the filter structure 5.

[0074] The wet curtain 4 has the function of evaporating the soaking liquid, so that the soaking liquid changes from liquid to gaseous state and absorbs heat, thereby taking away the heat in the air. While humidifying the air, it also cools the air, making the air blown out by the air outlet equipment have lower temperature and humidity.

[0075] The evaporative cooling pad 4 is specifically a sheet-like structure, which can be configured into circular, elliptical, or geometric shapes as needed. In this embodiment, the evaporative cooling pad 4 is configured as a rectangular sheet-like structure to fit and be installed within a rectangular mounting cavity.

[0076] Accordingly, the filter structure 5 can be configured as a sheet structure, and can be shaped as a circle, ellipse, or geometric shape as needed. In this embodiment, the filter structure 5 is configured as a rectangular mesh structure to fit and be installed within a rectangular mounting cavity.

[0077] Specifically, a carbon adsorption layer can be provided on the filter structure 5 to adsorb dust and other impurities in the air. In other embodiments, different materials can be selected on the filter structure 5 to filter substances such as formaldehyde in the air, depending on the purification requirements.

[0078] like Figure 1 , Figure 2 and Figure 6 As shown, in some specific embodiments, the air outlet device also includes a water circuit assembly 6 connected to the wet curtain 4. When the bracket 3 is in the first use state, the water circuit assembly 6 is turned on to provide wetting liquid to the wet curtain 4. When the bracket 3 is in the second use state, the water circuit assembly 6 is turned off.

[0079] The water circuit assembly 6 is used to provide humidifying liquid to the wet curtain 4 when the bracket 3 is in the first use state, so as to keep the wet curtain 4 moist and ensure the humidification effect of the air. When the bracket 3 is in the second use state, the water circuit assembly 6 is turned off to ensure the normal use of the filter structure 5.

[0080] It should be noted here that the soaking liquid can be water or an aqueous solution.

[0081] like Figures 6 to 8 As shown, in a preferred technical solution, the air outlet device further includes a control component 7, which is coupled to the water circuit component 6. When the bracket 3 is in the second use state, the control component 7 controls the water circuit component 6 to close.

[0082] A control component 7 is further configured, which is coupled with the water circuit component 6. When the bracket 3 is in the second use state, the control component 7 controls the water circuit component 6 to close, thereby achieving automated control of the water circuit component 6 and improving control efficiency.

[0083] Of course, in actual use, when bracket 3 is in the second use state, the water circuit component 6 can also be manually shut off.

[0084] In terms of specific structure, the control component 7 includes a proximity switch 71 and a magnetic element 72. The proximity switch 71 is mounted on the bracket 3 and coupled to the water circuit component 6. The magnetic element 72 is mounted on the filter structure 5. When the bracket 3 is in the second use state, the magnetic element 72 corresponds to the proximity switch 71 to trigger the proximity switch 71 to control the water circuit component 6 to close.

[0085] With the above configuration, when the bracket 3 is in the second use state, the filter structure 5 is installed on the bracket 3, and the magnetic component 72 on the filter structure 5 corresponds to the proximity switch 71, thereby triggering the proximity switch 71 to control the water circuit assembly 6 to close, so as to prevent the wetting liquid in the water circuit assembly 6 from wetting the filter structure 5 and ensuring the normal use function of the filter structure 5.

[0086] like Figures 5 to 8 As shown, the bracket 3 includes a support body 31, which is suitable for mounting the evaporative cooling pad 4 or the filter structure 5. A groove 311 is provided on the edge of the support body 31, and a proximity switch 71 is disposed within the groove 311. The support body 31 is used to support and fix the evaporative cooling pad 4 or the filter structure 5. The groove 311 is provided along the edge of the support body 31 to avoid obstructing the installation of the evaporative cooling pad 4 or the filter structure 5. The groove 311 can also position the proximity switch 71, improving installation stability.

[0087] Furthermore, a locking protrusion 33 is provided along one edge of the support body 31. The locking protrusion 33 engages and limits the evaporative cooling pad 4 or filter structure 5 installed on the support body 31, preventing it from detaching from the bracket 3. Multiple locking protrusions 33 can be provided along the edge of the support body 31 to enhance the engagement effect on the evaporative cooling pad 4 or filter structure 5.

[0088] In addition, a baffle plate 32 is provided on the other side of the support body 31. The baffle plate 32 and the latch 33 are used for the installation of the wet curtain 4 or the filter structure 5. The baffle plate 32 can block the wet liquid overflowing from the surface of the wet curtain 4 and prevent it from dripping from the wet curtain 4.

[0089] Multiple water baffles 32 can be spaced out along the height direction of the supporting body 31.

[0090] It is understandable that both the wet curtain 4 and the filter structure 5 are sheet-like structures with a certain degree of deformation capability. During installation and disassembly, the wet curtain 4 or the filter structure 5 is first bent and deformed to facilitate its removal from the bracket 3.

[0091] Furthermore, the water circuit assembly 6 includes a water tank 61, a water pump 62, and a water outlet pipe 63. The water tank 61 is disposed on the base 1, the water pump 62 is disposed in the water tank 61, the water pump 62 is coupled to the proximity switch 71, one end of the water outlet pipe 63 is connected to the water pump 62, and the other end of the water outlet pipe 63 provides the wet curtain 4 with the soaking liquid.

[0092] In the above configuration, the water tank 61 is used to store the soaking liquid, and the water pump 62 can transport the soaking liquid in the water tank 61 to the water outlet pipe 63. The soaking liquid then flows out to the wet curtain 4 through the water outlet pipe 63 to keep the wet curtain 4 moist. The water pump 62 is coupled with the proximity switch 71. When the bracket 3 is in the second use state, the water pump 62 can be turned off by controlling the proximity switch 71.

[0093] Regarding the specific installation of the water tank 61, a vertical mounting cavity can be set on the vertical support 11. The bottom of the vertical mounting cavity is connected to the chassis 12. The water tank 61 is snapped into the vertical mounting cavity and the bottom of the water tank 61 is placed on the chassis 12 to achieve installation and fixation.

[0094] To facilitate observation of the liquid level in the water tank 61 and allow users to replenish the wetting liquid in a timely manner, a water level gauge 65 can be installed on the surface of the water tank 61 to provide timely feedback on the liquid level in the water tank 61.

[0095] The water pump 62 is located at the bottom of the water tank 61 so that the water pump 62 can transport the wetting liquid in the water tank 61 at a low level.

[0096] One end of the outlet pipe 63 passes through the wall of the water tank 61 and is connected to the water pump 62 inside. The other end of the outlet pipe 63 is sealed to the wall of the water tank 61, so that the soaking liquid in the water pump 62 can flow into the outlet pipe 63.

[0097] The water outlet pipe 63 is distributed along the vertical support 11 and extends to the top of the vertical support 11 to be connected and fixed to the bracket 3. Preferably, the water outlet pipe 63 is a flexible hose, which facilitates pipe routing and installation.

[0098] Furthermore, the support 3 is also provided with a liquid distribution mechanism, which includes an inlet 312 and a liquid distribution hole 313. The inlet 312 is connected to the outlet pipe 63, and the liquid distribution hole 313 is distributed along the upper edge of the support 3. The liquid distribution hole 313 is connected to the inlet 312.

[0099] The above configuration, by distributing the liquid distribution holes 313 along the upper edge of the bracket 3, when the bracket 3 is in use, allows the wetting liquid in the water tank 61 to flow into the water outlet pipe 63 through the water pump 62, and then from the water outlet pipe 63 to the water inlet 312, and then from the water inlet 312 to the liquid distribution holes 313. The liquid is then evenly distributed downwards along the upper edge of the bracket 3 onto the wet curtain 4 through the liquid distribution holes 313, so as to evenly wet the wet curtain 4.

[0100] Specifically, the water inlet 312 is located on the side of the support 3, and multiple liquid distribution holes 313 are evenly distributed along the upper edge of the support 3. A water passage can be provided between the water inlet 312 and the liquid distribution holes 313 to connect the water inlet 312 and the liquid distribution holes 313.

[0101] Of course, the water passage can be a cavity opened on the bracket 3, with one end of the cavity connected to the water inlet 312 and the other end of the cavity connected to the liquid distribution hole 313; the water passage can also be an independently set pipeline, with one end of the pipeline connected to the water inlet 312 and the other end of the pipeline connected to the liquid distribution hole 313.

[0102] In this embodiment, the water outlet pipe 63 has two water outlet branches, which are respectively connected to the water inlets 312 on the two side supports 3 to simultaneously provide wet liquid to the wet curtains 4 on the two side supports 3.

[0103] In some embodiments, the lower edge of the bracket 3 is also provided with a water return port 314, and the water circuit assembly 6 also includes a water return pipe 64, one end of which is connected to the water return port 314, and the other end of which is connected to the water tank 61.

[0104] Furthermore, a return water inlet 314 is provided at the lower edge of the support 3. When excess soaking liquid on the wet curtain 4 leaches out and flows to the lower edge of the support 3, it can flow into the return water pipe 64 through the return water inlet 314 and then flow back to the water tank 61 through the return water pipe 64, thereby realizing the recycling of the soaking liquid and preventing the soaking liquid from flowing to the outside and causing pollution.

[0105] Specifically, a return water tank can be set on the side of the lower edge of the bracket 3 facing the wet curtain 4. The return water tank and the bottom edge of the wet curtain 4 are correspondingly set. The return water inlet 314 is connected to the return water tank so that the soaking liquid leached from the bottom edge of the wet curtain 4 can flow into the return water tank and flow into the return water pipe 64 through the return water inlet 314, thereby realizing the collection and recycling of the soaking liquid.

[0106] In this embodiment, the return water pipe 64 has two return water branches, which are respectively connected to the return water inlets 314 on the two side supports 3, so as to recover the soaking liquid leached from the wet curtain 4 on the two side supports 3 in a timely manner.

[0107] like Figure 3 , Figure 6 , Figure 7 and Figure 9 As shown, in addition, the air outlet device in this embodiment also includes a support frame 8, which is disposed opposite to the air inlets 21 at both ends of the cover 2. The support frame 8 is fixedly connected to the base 1, and a bracket 3 is provided on the support frame 8.

[0108] The support frame 8 can provide fixed support for the bracket 3. The bracket 3 is fixedly connected to the machine base 1 through the support frame 8, and then the bracket 3 is placed on the support frame 8, so that the force on the bracket 3 is transmitted to the machine base 1 through the support frame 8, thereby achieving force support.

[0109] Specifically, the shape of the support frame 8 matches the shape of the air inlet 21. Since the air inlet 21 is formed at the end opening of the cover 2 and is circular, the support frame 8 is also set as a circular frame.

[0110] Furthermore, to allow air to pass smoothly through the support frame 8, it is preferable to set the support frame 8 as a grid structure. Air can flow through the gaps in the grid structure through the support frame 8, which can also reduce weight.

[0111] Furthermore, the area of ​​bracket 3 is smaller than that of support frame 8. Bracket 3 is installed at the center of support frame 8 and is located on the side of support frame 8 away from cover 2. Bracket 3 and support frame 8 can be fixedly connected by bolts or snap-fit.

[0112] like Figure 3 and Figure 10 As shown, in this embodiment, the air outlet device also includes an air supply component 9, which is rotatably disposed inside the housing 2. The air supply component 9 is used to draw air from the air inlet 21 into the housing 2 and deliver it to the air outlet 22.

[0113] The air supply component 9 is further provided. By rotating the air supply component 9, the air in the air inlet 21 can be drawn into the cover 2 and sent out to the air outlet 22, so as to realize the dynamic circulation of air.

[0114] In terms of specific structure, the air supply assembly 9 includes a centrifugal impeller 91 and an air supply motor 92. The centrifugal impeller 91 is rotatably disposed inside the housing 2. Centrifugal fan blades 911 are arranged circumferentially on the centrifugal impeller 91. The output shaft of the air supply motor 92 is fixedly connected to the center of the centrifugal impeller 91 to drive the centrifugal impeller 91 to rotate.

[0115] The blower motor 92 drives the centrifugal impeller 91 to rotate inside the casing 2, so that a negative pressure is formed inside the casing 2. Under the action of negative pressure, air flows into the casing 2 from the air inlet 21 and flows to the centrifugal fan blade 911 through the centrifugal fan blade 911, and is delivered to the air outlet 22 through the centrifugal fan blade 911.

[0116] The centrifugal impeller 91 and the casing 2 are arranged concentrically, and the diameter of the centrifugal impeller 91 is smaller than the diameter of the casing 2 so that the centrifugal impeller 91 can rotate freely inside the casing 2.

[0117] In this embodiment, the centrifugal impeller 91 is a double-inlet centrifugal impeller 91, with its two ends of the air inlet facing the air inlets 21 at both ends of the cover 2, so that when the centrifugal impeller 91 rotates, it can draw in the air from the air inlets 21 on both sides of the cover 2 and send the air to the air outlet 22 through the centrifugal fan blades 911 around the centrifugal impeller 91.

[0118] Furthermore, the centrifugal impeller 91 is located between the supports 3 on both sides and is correspondingly set with the wet curtain 4 or the filter structure 5. When the centrifugal impeller 91 rotates, the air is treated by the wet curtain 4 or the filter structure 5 and then enters the centrifugal impeller 91 through the air inlet 21. Finally, it flows to the air outlet 22 through the centrifugal fan blades 911 around the centrifugal impeller 91.

[0119] The centrifugal impeller 91 has a shaft hole at its center, and the output shaft of the blower motor 92 is fixed in the shaft hole so that the output shaft and the centrifugal impeller 91 rotate coaxially.

[0120] like Figure 3 , Figure 11 , Figure 12 As shown, in an optional embodiment, the air outlet device further includes a guide air duct 10, which is disposed inside the housing 2 and covers the outer periphery of the centrifugal impeller 91. The guide air duct 10 has a guide inlet and a guide outlet, the guide inlet and the air inlet 21 are connected to each other, and the guide outlet and the air outlet 22 are connected to each other.

[0121] By further configuring the airflow guide duct 10, which covers the outer periphery of the centrifugal impeller 91, when the centrifugal impeller 91 rotates, air enters the centrifugal impeller 91 along the air inlet 21 and the airflow guide inlet, and flows to the airflow guide outlet through the centrifugal action of the centrifugal impeller 91, and finally flows out through the air outlet 22. It can be seen that the airflow guide duct 10 can guide the flowing air, so that the air drawn in from the air inlet 21 can be guided by the airflow guide duct 10 to flow out through the airflow guide outlet to the air outlet 22, avoiding airflow turbulence and reducing airflow noise.

[0122] In this embodiment, the air duct 10 and the housing 2 are fixedly connected. The air outlet device also includes an air outlet adjustment component 20, which is connected to the air duct 10 and is used to drive the air duct 10 and the housing 2 to rotate together to adjust the position of the air outlet 22 on the housing 2.

[0123] By fixing the air duct 10 and the housing 2 together, the air duct 10 is driven to rotate by the air outlet adjustment component 20, which in turn drives the housing 2 to rotate together. This allows the air outlet 22 on the housing 2 to rotate around the circumference of the housing 2, thereby adjusting the air outlet position to meet diverse air outlet needs.

[0124] Specifically, the air outlet adjustment assembly 20 includes an adjustment motor 201, which is connected to a support frame 8 at one end of the housing 2. The output shaft of the adjustment motor 201 is fixedly connected to the center of the air duct 10.

[0125] The regulating motor 201 is connected to the support frame 8 at one end of the cover 2, the air duct 10 is connected to the output shaft of the regulating motor 201, and the cover 2 is connected to the air duct 10. Therefore, the cover 2, the air duct 10 and the regulating motor 201 can all be supported by the support frame 8 at one end of the cover 2. The regulating motor 201 drives the air duct 10 to rotate, so as to drive the cover 2 to rotate synchronously.

[0126] In this embodiment, the air duct 10 includes a first air duct 101 and a second air duct 102. The first air duct 101 and the air inlet 21 at one end of the cover 2 are correspondingly arranged. The first air duct 101 is provided with a first mounting bracket 1013. The output shaft of the adjusting motor 201 is connected to the first mounting bracket 1013 through a first bushing 202. The second air duct 102 is connected to the first air duct 101. At least one of the first air duct 101 and the second air duct 102 is connected to the cover 2. The second air duct 102 and the air inlet 21 at the other end of the cover 2 are correspondingly arranged. The centrifugal impeller 91 is arranged between the second air duct 102 and the first air duct 101. The second air duct 102 is provided with a second mounting bracket 1023. The blower motor 92 is arranged on the second mounting bracket 1023. The second mounting bracket 1023 and the support frame 8 at the other end of the cover 2 are rotatably connected.

[0127] It is understandable that by setting the airflow duct 10 into the form of a first airflow duct 101 and a second airflow duct 102, the first airflow duct 101 and the second airflow duct 102 are respectively set to correspond to the air inlets 21 on both sides of the cover 2, so as to guide the air entering from the air inlets 21 on both sides. The output shaft of the regulating motor 201 is connected to the first mounting bracket 1013 through the first bushing 202, thereby realizing the connection between the regulating motor 201 and the first airflow duct 101. The blower motor 92 is mounted on the second airflow duct 102 through the second mounting bracket 1023, and the second airflow duct 102 is rotatably coupled to the support bracket 8 at the other end of the cover 2 through the second mounting bracket 1023 to achieve force support. When the regulating motor 201 drives the first airflow duct 101 to rotate, it drives the second airflow duct 102, the blower motor 92 and the cover 2 to rotate synchronously. At the same time, the second airflow duct 102 rotates relative to the support bracket 8 at the other end of the cover 2 through the second mounting bracket 1023.

[0128] It should be noted that when the regulating motor 201 drives the second air duct 102 to rotate, it also drives the air supply motor 92 to rotate. The air supply motor 92 is used to drive the centrifugal impeller 91 to rotate. Therefore, the regulating motor 201 and the air supply motor 92 rotate in the same direction. The regulating motor 201 is only turned on when the position of the air outlet 22 needs to be changed. At this time, the regulating motor 201 and the air supply motor 92 run simultaneously. When the position of the air outlet 22 is fixed (i.e., the air outlet angle of the air outlet equipment is fixed), the regulating motor 201 is turned off, and the air supply motor 92 is kept running.

[0129] Specifically, both the first air duct 101 and the second air duct 102 are volutes, with the volute tongue facing the air outlet 22 to control the incoming air to flow along the volute tongue to the air outlet 22.

[0130] The first air duct 101 has a first inlet 1011, which corresponds to the air inlet 21 at one end of the cover 2. The second air duct 102 has a second inlet 1021, which corresponds to the air inlet 21 at the other end of the cover 2. The first inlet 1011 and the second inlet 1021 are the guide inlets. The first air duct 101 has a first outlet 1012, and the second air duct 102 has a second outlet 1022. The first outlet 1012 and the second outlet 1022 are connected and cooperated to form the guide outlet.

[0131] The edges of the first air duct 101 and the second air duct 102 can be fixed with bolts, and the inner wall of the cover 2 is fixedly connected to the outer wall of the first air duct 101 or the second air duct 102.

[0132] To prevent the first bushing 202 from coming off the output shaft of the regulating motor 201, the air outlet regulating component 20 in this embodiment also includes a first limiting sleeve 203. The first limiting sleeve 203 is connected and fixed to the support frame 8 at one end of the cover 2, and the first limiting sleeve 203 is sleeved on the outer periphery of the first bushing 202. The first limiting sleeve 203 limits the end of the first bushing 202 to prevent the first limiting sleeve 203 from coming off the output shaft of the regulating motor 201 during rotation.

[0133] It should be noted that the first bushing 202 is fitted with the first limiting sleeve 203 with a clearance so that the first bushing 202 can rotate within the first limiting sleeve 203.

[0134] The output shaft of the blower motor 92 passes through the second air duct 102 and is fixedly connected to the shaft hole of the centrifugal impeller 91. The end of the output shaft of the blower motor 92 is locked to the centrifugal impeller 91 by the fan blade knob.

[0135] The second mounting bracket 1023 and the support bracket 8 at the other end of the cover 2 are connected by a rotating connector 30. Specifically, the rotating connector 30 includes a rotating shaft 301, a second bushing 302, and a second limiting sleeve 303. The rotating shaft 301 is rotatably mounted on the support bracket 8 at the other end of the cover 2. The second bushing 302 is sleeved on the rotating shaft 301. The second limiting sleeve 303 is fixedly connected to the second mounting bracket 1023. The second bushing 302 is rotatably fitted inside the second limiting sleeve 303, and the second limiting sleeve 303 limits the end of the second bushing 302 facing the blower motor 92 to prevent the second air duct 102 and the support bracket 8 at the other end of the cover 2 from loosening during rotation.

[0136] In addition to the above-mentioned settings, in order to improve the uniformity of air intake at the air inlet 21, the air outlet device of this embodiment also includes an air intake grille 40. The air intake grille 40 and the support frame 8 are fixedly connected, and the air intake grille 40 is covered outside the support 3 so that the air flows evenly through the air intake grille 40 before flowing to the wet curtain 4 or the filter structure 5.

[0137] Accordingly, the air outlet device in this embodiment also includes an air outlet grille 50, which is fixedly connected to the cover 2 and located at the air outlet 22, so that the humidified or purified air flows evenly into the room after passing through the air outlet grille 50, thereby improving the user experience.

[0138] To facilitate understanding of the air outlet device in this embodiment, the following is now combined with Figures 1 to 12 The usage process is described as follows:

[0139] When the air supply equipment needs to humidify and cool the air, the wet curtain 4 is installed on the bracket 3, the bracket 3 is in the first use state, the blower motor 92 rotates, driving the centrifugal impeller 91 to rotate, the air flows to the wet curtain 4 through the air inlet grille 40, the soaking liquid in the water tank 61 enters the water outlet pipe 63 through the water pump 62, flows to the liquid distribution hole 313 through the water outlet pipe 63 and the water inlet 312, and is evenly distributed on the wet curtain 4 through the liquid distribution hole 313 to wet the wet curtain 4, the soaking liquid overflowing from the wet curtain 4 flows into the return water pipe 64 through the return water inlet 314, and then flows back into the water tank 61, the air is humidified and cooled by the wet curtain 4 and flows to the centrifugal impeller 91 through the guide inlet, and flows to the guide outlet through the centrifugal action of the centrifugal impeller 91, and then blown out through the air outlet grille 50 at the air outlet 22;

[0140] When the air outlet equipment needs to filter and purify the air, the wet curtain 4 is removed from the bracket 3 and the filter structure 5 is installed on the bracket 3. The bracket 3 is in the second use state. At this time, the magnetic component 72 on the filter structure 5 corresponds to the proximity switch 71, thereby triggering the proximity switch 71 to control the water pump 62 to shut down, the blower motor 92 to rotate, and the centrifugal impeller 91 to rotate. The air flows through the air inlet grille 40 to the filter structure 5. After being filtered and purified by the filter structure 5, the air flows through the guide inlet to the centrifugal impeller 91, and flows through the centrifugal action of the centrifugal impeller 91 to the guide outlet, and then is blown out through the air outlet grille 50 at the air outlet 22.

[0141] When the position of the air outlet 22 needs to be adjusted, the adjusting motor 201 drives the air guide duct 10 to rotate, which in turn drives the cover 2 to rotate together, so that the air outlet 22 on the cover 2 rotates around the circumference of the cover 2, thereby realizing the adjustment of the air outlet position.

[0142] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
