Description

Technical Field

[0001] This application relates to the technical field of air outlet devices, and more specifically, to an air outlet structure and an air outlet fan. Background Art

[0002] As an indispensable electrical appliance product in modern household and personal care, the hair dryer is deeply loved by users for its high efficiency and convenience. It mainly drives the fan blades to rotate through an internal motor, sucks in the surrounding air and heats it through a heating element (for products with hot air function), and finally blows out warm or cool airflows for quickly drying hair, styling hair, or increasing the luster and softness of hair.

[0003] Most of the air blown out by conventional hair dryers is in a straight air beam. For large, hairy pets (such as dogs, cats, etc.), the area that can be blown by this type of hair dryer is relatively small, and it takes a long time to dry the pet's whole body and it is easy to have uneven drying; in addition, because the air beam blown out by this type of fan is relatively concentrated, when the fan blows out hot air, the temperature in the area affected by the air beam is too high for the sensitive and delicate fur of the pet, which is likely to cause damage to the pet's hair or cause discomfort and anxiety to the pet. Conventional hair dryers are difficult to meet the usage needs of users who want to dry or care for the hair of their pets together. Summary of the Invention

[0004] The purpose of this application is to provide an air outlet structure and an air outlet fan to address the above problems and improve the situation.

[0005] This application is implemented through the following technical solutions:

[0006] In a first aspect, this application provides an air outlet structure. The air outlet structure includes a baffle, a first housing, and a flow guiding component. The baffle is provided with a first air outlet, and the first air outlet is annular, surrounding the center of the baffle and close to the edge of the baffle; the first housing is connected to the baffle, and the first housing has a first installation port and a second installation port. The first installation port is blocked by the baffle, and the baffle and the first housing enclose an air cavity for accommodating fluid, and the first air outlet of the baffle communicates with the air cavity; the flow guiding component is located in the air cavity and is connected to the baffle and the first housing, and the flow guiding component and the inner wall of the first housing enclose a first flow channel communicating with the first air outlet.

[0007] In the technical solution of the embodiment of the present application, the first housing has a first mounting port and a second mounting port. The baffle and the first housing enclose a wind cavity for passing and accommodating fluid. Wind enters the wind cavity from the second mounting port and then moves to the first mounting port. The first air outlet of the baffle communicates with the wind cavity. After the wind in the wind cavity is blocked by the baffle, it will pass through at the first air outlet. The first air outlet is annular, and the first air outlet surrounds the center of the baffle and is close to the edge of the baffle, so that the wind passing through the first air outlet blows out in a dispersed annular shape, increasing the coverage area of the wind and improving the uniform drying effect on the whole body of a hairy pet or long hair. In addition, making the influence area of the wind relatively dispersed can make the heat applied to the hair by the blown wind relatively dispersed, reducing the discomfort or restlessness stress reaction of the pet caused by the over-high temperature in a local area due to the hot wind. Moreover, making the wind more dispersed through the shape of the first air outlet can also reduce the intensity of the wind that can be felt in the area being blown, making the wind blown by the hair dryer provided with the air outlet structure of the present application a soft wind, reducing the risk that the pet is frightened by the sudden stimulation of strong wind, and enabling the user to dry and care for the hair together with the pet. The diversion component is located in the wind cavity. The diversion component and the inner wall of the first housing enclose a first flow channel communicating with the first air outlet. The wind in the wind cavity is dispersed and guided to the first air outlet through the first flow channel, reducing the impact of the wind on the baffle. On the one hand, it reduces the risk of damage to the baffle under the continuous pressure of the wind force. On the other hand, it avoids the baffle being continuously impacted by the hot wind, resulting in the temperature of the baffle being too high. The baffle may come into contact with the body of the user or the pet, reducing the risk that the too-high temperature of the baffle scares the user or the pet, and improving the use comfort of the hair blowing device applying the air outlet structure provided by the present application.

[0008] In some embodiments, the diversion component includes a first section and a second section. The first section is connected to the baffle, and the second section is closer to the second mounting port than the first section. The dimension of the second section in the height direction of the first housing gradually decreases from the first mounting port to the second mounting port.

[0009] In the technical solution of the embodiment of the present application, the diversion component includes a first section and a second section. The size of the second section in the height direction of the first housing gradually decreases from the first installation opening to the second installation opening, enabling the wind in the wind cavity to be more easily guided by the second section into the first flow channel, reducing the residence time of the wind in the wind cavity, thereby reducing the internal pressure on the first housing during use, making the first housing not easily damaged due to internal pressure, and extending the service life of the first housing; the flow velocity of the wind is inversely proportional to the width of the flow-through area, that is, the smaller the size of the first channel in the height direction of the first housing, the faster the speed of the wind passing through the first channel. The size of the second section in the height direction of the first housing gradually decreases from the first installation opening to the second installation opening, making the size of the part where the wind enters the first flow channel larger and the size of other parts smaller, causing the wind to accelerate after entering the first flow channel, thereby increasing the speed of the wind in the wind cavity being blown out from the first air outlet through the first flow channel, so that the air volume blown out from the first air outlet is larger, meeting the requirement of drying the hair of people or pets.

[0010] In some embodiments, the size of the first housing in its own height direction and / or the size of the first housing in its own width direction gradually decreases from the first installation opening to the second installation opening, and the outer wall of the first section is parallel to the inner wall of the first housing.

[0011] In the technical solution of the embodiment of the present application, the size of the first housing in its own height direction and / or the size of the first housing in its own width direction gradually decreases from the first installation opening to the second installation opening, making the size of the ring formed by the first air outlet larger. The wind entering the wind cavity from the second installation opening can diffuse along the first housing and then decelerate, and then be blown out through the first air outlet, reducing the wind force of the wind blown out from the first air outlet and the risk of scaring pets with too strong wind force. The outer wall of the first section is parallel to the inner wall of the first housing, enabling the gas passing through a part of the first flow channel between the first section and the first housing to move at a uniform speed, so that the wind can be blown out from the first air outlet in a relatively uniform and gentle state, reducing the stimulation brought to the user or pet by the air outlet.

[0012] In some embodiments, the inner wall of the first air outlet is inclined towards the center of the baffle, and the distance between the inner wall of the first air outlet and the center of the baffle gradually decreases from the side of the first air outlet facing away from the wind cavity to the side of the first air outlet facing the wind cavity.

[0013] In the technical solution of the embodiment of the present application, the inner wall of the first air outlet is inclined towards the center of the baffle. The inclination angles at various parts of the first air outlet can be the same as the inclination angles of the corresponding parts of the first flow channel, so that the air in the first flow channel can smoothly pass through the first air outlet and blow out; the inclined first air outlet can make the air blow obliquely towards the hair of people or pets, reducing the sense of stimulation caused by the direct impact of the air on the skin when the direction of the air is perpendicular to the skin surface, and improving the use comfort of the hair dryer using the air outlet structure provided by the present application.

[0014] In some embodiments, the inner wall of the first air outlet is flush with the outer wall of the first section.

[0015] In the technical solution of the embodiment of the present application, the inner wall of the first air outlet is flush with the outer wall of the first section, so that the air flowing through the first channel can smoothly enter the first air outlet and is not easily blocked by the baffle to generate noise, reducing the decibel of the noise generated when the air outlet structure provided by the present application works, making the noise generated when using the hair dryer using the air outlet structure provided by the present application smaller, and not easily scaring or causing discomfort to pets.

[0016] In some embodiments, the size of the baffle in the width direction of the first housing is greater than the size of the baffle in the height direction of the first housing.

[0017] In the technical solution of the embodiment of the present application, the size of the baffle in the width direction of the first housing is greater than the size of the baffle in the height direction of the first housing, increasing the coverage area of the air blown out from the first air outlet in the width direction of the first housing, thereby accelerating the drying speed of the hair of people or pets, making the drying process more controllable and not easily leaving omissions.

[0018] In some embodiments, the first air outlet includes a plurality of port segments, the plurality of port segments are distributed around the center of the baffle, a first connecting portion is provided between any two adjacent port segments among the plurality of port segments, the flow guiding assembly is connected to the inner wall of the first housing through a plurality of first connecting plates, and the first connecting plates are connected to the first connecting portion.

[0019] In the technical solution of the embodiment of the present application, a first connecting portion is provided between any two adjacent port segments among the plurality of port segments, enhancing the connection strength between the part of the baffle located inside the annular first air outlet and the part of the baffle located outside the first air outlet. The flow guiding assembly is connected to the inner wall of the first housing through a plurality of first connecting plates, and the first connecting plates are connected to the first connecting portion. On the one hand, the first connecting plates can enhance the strength of the first connecting portion, and on the other hand, they can block the first connecting portion, reducing the risk of damage to the first connecting portion caused by the heat and impact force brought by the air in the air cavity when passing through the port segments, and improving the service life of the first connecting portion.

[0020] In some embodiments, the first connecting plate extends along the length direction of the first housing and does not exceed the flow guiding assembly.

[0021] In the technical solution of the embodiment of the present application, along the length direction of the first housing, the first connecting plate enables the wind in the wind cavity to pass through the first flow channel at the shortest distance.

[0022] In some embodiments, the baffle is further provided with a plurality of second air outlets. The first air outlet is closer to the edge of the baffle than the second air outlets. The second air outlets are annular and arranged around the center of the baffle. The plurality of second air outlets are arranged in sequence along the connection line between any point from the center of the baffle to the edge of the baffle.

[0023] In the technical solution of the embodiment of the present application, the baffle is further provided with a plurality of second air outlets. The second air outlets are annular and arranged around the center of the baffle. The plurality of second air outlets are arranged in sequence along the connection line between any point from the center of the baffle to the edge of the baffle. The plurality of second air outlets further disperse the wind blown out through the baffle, so that the wind blown out through the baffle changes from the speed of drying hair to the speed of drying hair. The second air outlet can be blocked. When the second air outlet is blocked, the air is blown out from the first air outlet, and the relatively fast wind speed can dry the hair. When the second air outlet is opened, the air is blown out from the first air outlet and the second air outlets together, and the relatively slow wind speed can dry the hair or perform hot compress heating care on local parts of the body, etc., meeting the diverse needs of users.

[0024] In some embodiments, the flow guiding assembly is composed of a plurality of flow guiding sleeves sleeved with each other from inside to outside in sequence. Any two adjacent flow guiding sleeves among the plurality of flow guiding sleeves enclose a second flow channel communicating with the second air outlet.

[0025] In the technical solution of the embodiment of the present application, the flow guiding assembly is composed of a plurality of flow guiding sleeves sleeved with each other from inside to outside in sequence. Any two adjacent flow guiding sleeves among the plurality of flow guiding sleeves enclose a second flow channel communicating with the second air outlet. The plurality of second flow channels disperse and guide the wind in the wind cavity to the second opening, enabling the wind to pass through the second air outlet more smoothly, and reducing the risk that the wind in the wind cavity impacts the baffle near the second air outlet to generate noise and affect the use experience of the air outlet structure provided by the present application.

[0026] In some embodiments, in the length direction of the first housing, the spacing distance between the flow guiding sleeve and the second mounting opening gradually decreases from the outermost flow guiding sleeve among the plurality of flow guiding sleeves to the innermost flow guiding sleeve among the plurality of flow guiding sleeves.

[0027] In the technical solution of the embodiment of the present application, the spacing distance between the flow guide sleeve and the second installation port gradually decreases from the outermost flow guide sleeve among the multiple flow guide sleeves to the innermost flow guide sleeve among the multiple flow guide sleeves. During the process of the wind in the wind cavity moving from the direction of the second installation port towards the first installation port, the wind speed gradually slows down. The innermost flow guide sleeve among the multiple flow guide sleeves is close to the second installation port, that is, the wind with the largest volume and the fastest speed will first contact the opening of the innermost flow guide sleeve. Although the volume of air is large, due to the relatively fast flow rate of the wind, the amount of air that just enters the opening of this flow guide sleeve will not be too much. The outermost flow guide sleeve among the multiple flow guide sleeves is far from the second installation port, that is, the wind with the smallest volume and the slowest speed will finally contact the opening of the outermost flow guide sleeve. Although the volume of air is small, due to the relatively slow flow rate of the wind, the amount of air that just enters the opening of this flow guide sleeve will be more. Through the distribution of the positions of the openings of the multiple flow guide sleeves, the amount of air entering each second channel is made similar, so that the wind passing through the baffle can be blown out more evenly, improving the user experience.

[0028] In a second aspect, the present application provides an air outlet fan, which includes a second housing, the air outlet structure of the first aspect, and a power mechanism. The second housing has a first air inlet end and a first air outlet end; the air outlet structure is inserted into the first air outlet end of the second housing, and the first air outlet end is flush with the baffle; the power mechanism is arranged inside the second housing, and the power mechanism is used to guide the fluid to move from the first air inlet end to the first air outlet end; wherein, the first air inlet end is provided with a plurality of through holes for air inlet.

[0029] In the technical solution of the embodiment of the present application, the air outlet structure is inserted into the first air outlet end of the second housing; the power mechanism is arranged inside the second housing. Air enters the second housing from the first air inlet end, and the power mechanism guides the air to move from the first air inlet end to the first air outlet end. The air enters the air outlet structure through the second installation port and is then blown out through the first air outlet and / or the second air outlet on the baffle, which can meet the needs of shared use by humans and pets, and can also meet the needs of drying and caring for long or short hair.

[0030] In some embodiments, the second housing includes a first straight section, a second straight section, and a connecting section. The connecting section connects the first straight section and the second straight section. The first air outlet end is located at the first straight section, and the first air inlet end is located at the second straight section; the value range of the angle between the first straight section and the second straight section is 75° to 45°.

[0031] In the technical solution of the embodiment of the present application, the second housing includes a first straight section, a second straight section, and a connecting section. The connecting section connects the first straight section and the second straight section, making the hair dryer provided by the present application triangular as a whole. The range of the angle between the first straight section and the second straight section is from 75° to 45°. When the user holds the second straight section, the first air outlet end of the air blower can more easily reach the parts of a person or a pet that are blocked or difficult to reach, improving the convenience of the hair dryer provided by the present application.

[0032] In some embodiments, the dimension of the first straight section in its own length direction is the same as that of the second straight section in its own length direction; the end face of the first air inlet end is flush with the surface of the baffle plate facing away from the air cavity.

[0033] In the technical solution of the embodiment of the present application, the dimension of the first straight section in its own length direction is the same as that of the second straight section in its own length direction; the end face of the first air inlet end is flush with the surface of the baffle plate facing away from the air cavity. When the end face of the first air inlet end is in contact with the ground or the working platform, the baffle plate can also be in contact with the ground or the working platform. Thus, by supporting the ground or the working platform with the end face of the first air inlet end and the surface of the baffle plate facing away from the air cavity, the supporting device provided by the present application can stand up for placement, which is easier to store and also convenient for the user to grasp the first straight section or the second straight section to pick up the air blower provided by the present application.

[0034] In some embodiments, it further includes a heating module, a sound - generating module, and a switching switch. The switching switch is used to control the heating module to switch between a first state and a second state. When the heating module is in the first state, the heating module heats the fluid inside the second housing to T1. When the heating module is in the second state, the heating module heats the fluid inside the second housing to T2, where T1>T2. Among them, when the switching switch controls the heating module to switch from the first state to the second state, the sound - generating module emits a prompt sound.

[0035] In the technical solution of the embodiment of the present application, when the heating module is in the first state, the heating module heats the fluid inside the second housing to a temperature T1 suitable for human use. When the heating module is in the second state, the heating module heats the fluid inside the second housing to a temperature T2 suitable for pet use, enabling timely switching of the temperature according to the user's needs. When the switching switch controls the heating module to switch from the first state to the second state, the sound - generating module emits a prompt sound to prompt the user that a mode switch has been made, eliminating the trouble for the user to specifically confirm the state.

[0036] In some embodiments, it further includes a plug. The power mechanism is electrically connected to the plug through an electric wire. The plug includes a plug housing and a pin. The plug housing is provided with a baffle plate perpendicular to the length direction of the pin.

[0037] In the technical solution of the embodiment of the present application, most of the hair dryers provided by the present application are applied in relatively humid environments. The plug housing is provided with a baffle perpendicular to the length direction of the pin. When the plug is inserted into the power socket, the baffle can block the socket near itself, avoiding the situation that water splashes or flows along the wire into the socket during the drying process, which may cause safety accidents.

[0054] According to some embodiments of the present application, optionally, as Figures 4 to 7 shown, the present application provides an air outlet structure 1. The air outlet structure 1 includes a baffle 10, a first housing 11, and a flow guiding component 12. The baffle 10 is provided with a first air outlet 100. The first air outlet 100 is annular, surrounds the center of the baffle 10 and is close to the edge of the baffle 10. The first housing 11 is connected to the baffle 10. The first housing 11 has a first installation opening 110 and a second installation opening 111. The first installation opening 110 is blocked by the baffle 10. The baffle 10 and the first housing 11 enclose an air cavity 112 for accommodating fluid. The first air outlet 100 of the baffle 10 communicates with the air cavity 112. The flow guiding component 12 is located in the air cavity 112 and is connected to the baffle 10 and the first housing 11. The flow guiding component 12 and the inner wall of the first housing 11 enclose a first flow channel 113 that communicates with the first air outlet 100.

[0055] The edge of the baffle 10 can extend beyond the first housing 11.

[0056] The first housing 11 and the baffle 10 can be detachably connected, such as by snap fit, threaded connection, bonding, socket connection, etc.

[0057] The shape of the first air outlet 100 can be the same as the shape enclosed by the edge of the baffle 10, so that the air outlet positions on the first baffle 10 are farther from the center position of the baffle 10, making the blown air more dispersed.

[0058] The first housing 11 can be connected to the surface of the baffle 10 facing the air cavity 112. The first housing 11 can be fixedly connected or hermetically connected to the baffle 10, reducing the risk of air leakage between the two and improving the control effect on the flow direction of the air passing through the air cavity 112.

[0059] The fluid in the volume of this application is air.

[0060] The diversion component 12 can have a hollow inner structure to reduce the overall weight of the diversion component 12, making it easier for the user to pick up; alternatively, the diversion component 12 can be a solid structure to enhance the strength of the diversion component 12, reduce the risk of deformation of the diversion component 12 under the continuous blowing of hot air, and extend the service life of the diversion component 12.

[0061] The first housing 11 has a first mounting port 110 and a second mounting port 111. The baffle 10 and the first housing 11 enclose a wind cavity 112 for passing and receiving fluid. Wind enters the wind cavity 112 from the second mounting port 111 and then moves to the first mounting port 110. The first air outlet 100 of the baffle 10 is in communication with the wind cavity 112. After the wind in the wind cavity 112 is blocked by the baffle 10, it will pass through the first air outlet 100. The first air outlet 100 is annular, surrounds the center of the baffle 10 and is close to the edge of the baffle 10, so that the wind passing through the first air outlet 100 blows out in a dispersed annular shape, increasing the coverage area of the wind and improving the uniform drying effect on the whole body of a hairy pet or long hair; in addition, making the influence area of the wind more dispersed can make the heat applied to the hair by the blown wind more dispersed, reducing the discomfort or restlessness stress reactions of the pet caused by excessive local temperature due to hot air; furthermore, making the wind more dispersed through the shape of the first air outlet 100 can also reduce the intensity of the wind that can be felt in the area being blown, making the wind blown by the hair dryer with the air outlet structure 1 provided by the present application a soft wind, reducing the risk of the pet being frightened by the sudden stimulation of strong wind, and enabling the user to dry and care for the pet's hair together; the diversion component 12 is located in the wind cavity 112, and the diversion component 12 and the inner wall of the first housing 11 enclose a first flow channel 113 communicating with the first air outlet 100. The wind in the wind cavity 112 is dispersed and guided to the first air outlet 100 through the first flow channel 113, reducing the impact of the wind on the baffle 10. On the one hand, it reduces the risk of the baffle 10 being damaged under the continuous pressure of the wind force. On the other hand, it avoids the baffle 10 being continuously impacted by hot air, resulting in too high a temperature of the baffle 10. The baffle 10 may come into contact with the user's or pet's body, reducing the risk of the baffle 10 having too high a temperature and scaring the user or pet, and improving the use comfort of the hair drying device applying the air outlet structure 1 provided by the present application.

[0062] According to some embodiments of the present application, optionally, as Figure 5 shown, the diversion component 12 includes a first section 120 and a second section 121. The first section 120 is connected to the baffle 10, and the second section 121 is closer to the second mounting port 111 than the first section 120. The size of the second section 121 in the height direction of the first housing 11 gradually decreases from the first mounting port 110 to the second mounting port 111.

[0063] The surface of the second section 121 can be an arc surface, so that the wind blowing onto the second section 121 can be guided by the second section 121 more smoothly to the first flow channel 113 without easily impacting the second section 121 to generate noise, reducing the noise generated during the use of the air outlet structure 1 provided in the present application, and reducing the risk of pets being frightened by the noise or showing irritable emotions.

[0064] The flow guiding assembly 12 includes a first section 120 and a second section 121. The size of the second section 121 in the height direction of the first housing 11 gradually decreases from the first mounting opening 110 to the second mounting opening 111, enabling the wind in the wind cavity 112 to be more easily guided by the second section 121 into the first flow channel 113, reducing the residence time of the wind in the wind cavity 112, thereby reducing the internal pressure on the first housing 11 during use, making the first housing 11 not easily damaged due to the internal pressure, and extending the service life of the first housing 11; the flow velocity of the wind is inversely proportional to the width of the flowing-through area, that is, the smaller the size of the first channel in the height direction of the first housing 11, the faster the speed of the wind passing through the first channel. The size of the second section 121 in the height direction of the first housing 11 gradually decreases from the first mounting opening 110 to the second mounting opening 111, making the size of the part where the first flow channel 113 enters larger and the size of other parts smaller, causing the wind to accelerate after entering the first flow channel 113, thereby increasing the speed of the wind in the wind cavity 112 blowing out from the first air outlet 100 through the first flow channel 113, so that the air volume at the first air outlet 100 is relatively large, capable of meeting the need for drying the hair of people or pets.

[0065] According to some embodiments of the present application, optionally, as Figure 5 and Figure 7 shown, the size of the first housing 11 in its own height direction and / or the size of the first housing 11 in its own width direction gradually decreases from the first mounting opening 110 to the second mounting opening 111, and the outer wall of the first section 120 is parallel to the inner wall of the first housing 11.

[0066] The first housing 11 can be in a horn shape, the first mounting opening 110 is the wide opening of the first housing 11, and the second mounting opening 111 is the narrow opening of the first housing 11.

[0067] The dimension of the first housing 11 in its own height direction and / or the dimension of the first housing 11 in its own width direction gradually decreases from the first mounting opening 110 to the second mounting opening 111, so that the size of the ring formed by the first air outlet 100 is larger. The air entering the air cavity 112 from the second mounting opening 111 can diffuse along the first housing 11 and then decelerate, and then be blown out through the first air outlet 100, reducing the risk that the pet is frightened by the too strong wind force of the air blown out from the first air outlet 100. The outer wall of the first section 120 is parallel to the inner wall of the first housing 11, enabling the speed of the gas passing through a part of the first flow channel 113 between the first section 120 and the first housing 11 to move at a uniform speed, so that the air can be blown out from the first air outlet 100 in a relatively uniform and gentle state, reducing the stimulation brought to the user or the pet by the air outlet.

[0068] According to some embodiments of the present application, optionally, as Figure 5 and Figure 7 shown, the inner wall of the first air outlet 100 inclines towards the center of the baffle 10, and the distance between the inner wall of the first air outlet 100 and the center of the baffle 10 gradually decreases from the side of the first air outlet 100 facing away from the air cavity 112 to the side of the first air outlet 100 facing the air cavity 112.

[0069] The outer wall of the first air outlet 100 can be parallel to the inner wall of the first air outlet 100.

[0070] The inner wall of the first air outlet 100 inclines towards the center of the baffle 10, and the inclination angle of each part of the first air outlet 100 can be the same as the inclination angle of the corresponding part of the first flow channel 113, enabling the air in the first flow channel 113 to pass through the first air outlet 100 more smoothly; the inclined first air outlet 100 can make the air blow obliquely towards the hair of people or pets, reducing the sense of irritation caused by the direct impact of the air on the skin when the direction of the air is perpendicular to the skin surface, and improving the use comfort of the blowing device using the air outlet structure 1 provided by the present application.

[0071] According to some embodiments of the present application, optionally, as Figure 5 and Figure 7 shown, the inner wall of the first air outlet 100 is flush with the outer wall of the first section 120.

[0072] The outer wall of the first air outlet 100 can be flush with the inner wall of the first housing 11.

[0073] The inner wall of the first air outlet 100 is flush with the outer wall of the first section 120, allowing the air flowing through the first channel to smoothly enter the first air outlet 100 without being easily blocked by the baffle 10 to generate noise, reducing the decibel of the noise generated when the air outlet structure 1 provided in the present application works, making the noise generated when the blowing device using the air outlet structure 1 provided in the present application acts smaller, and not easily scaring or causing discomfort to pets.

[0074] According to some embodiments of the present application, optionally, as Figure 4 and Figure 6 shown, the size of the baffle 10 in the width direction of the first housing 11 is greater than the size of the baffle 10 in the height direction of the first housing 11.

[0075] In some embodiments, the size of the baffle 10 in the width direction of the first housing 11 may be smaller than the size of the baffle 10 in the height direction of the first housing 11.

[0076] The size of the baffle 10 in the width direction of the first housing 11 is greater than the size of the baffle 10 in the height direction of the first housing 11, increasing the coverage area of the air blown out from the first air outlet 100 in the width direction of the first housing 11, thereby accelerating the drying speed of the hair of people or pets, making the drying process more controllable and not easily leaving omissions.

[0077] According to some embodiments of the present application, optionally, as Figure 4 and Figure 6 shown, the first air outlet 100 includes a plurality of port segments 1000, the plurality of port segments 1000 are distributed around the center of the baffle 10, a first connecting portion 101 is provided between any two adjacent port segments 1000 among the plurality of port segments 1000, the flow guiding assembly 12 is connected to the inner wall of the first housing 11 through a plurality of first connecting plates 122, and the first connecting plate 122 is connected to the first connecting portion 101.

[0078] The number of the plurality of first connecting portions 101 is one less than the number of the plurality of port segments 1000.

[0079] The plurality of first connecting portions 101 and the plurality of first connecting plates 122 correspond one by one.

[0080] A first connecting portion 101 is provided between any two adjacent opening segments 1000 among the multiple opening segments 1000, so as to enhance the connection strength between the partial baffle 10 located on the inner side of the annular first air outlet 100 and the partial baffle 10 located on the outer side of the first air outlet 100. The air guide assembly 12 is connected to the inner wall of the first shell 11 through multiple first connecting plates 122, and the first connecting plate 122 is connected to the first connecting portion 101. On the one hand, the first connecting plate 122 can enhance the strength of the first connecting portion 101, and on the other hand, it can shield the first connecting portion 101, thereby reducing the risk of damage to the first connecting portion 101 caused by the heat and impact force brought to the first connecting portion 101 by the wind in the wind cavity 112 when passing through the opening segment 1000, thereby improving the service life of the first connecting portion 101.

[0081] According to some embodiments of the present application, optionally, Figure 5 and Figure 7 As shown, the first connecting plate 122 extends along the length direction of the first shell 11 and does not exceed the guide assembly 12 .

[0082] The first connecting plate 122 is arranged along the length direction of the first housing 11 , so that the wind in the wind cavity 112 can pass through the first flow channel 113 in the shortest distance.

[0083] According to some embodiments of the present application, optionally, Figures 6 to 7 As shown, the baffle 10 is also provided with a plurality of second air outlets 102. The first air outlet 100 is closer to the edge of the baffle 10 than the second air outlet 102. The second air outlet 102 is ring-shaped and arranged around the center of the baffle 10. The plurality of second air outlets 102 are arranged in sequence along a line between the center of the baffle 10 and any point on the edge of the baffle 10.

[0084] The second air outlets 102 are located at the innermost side. The second air outlet 102 may be a round hole or a special-shaped hole having the same shape as the edge of the baffle 10 , and the center point of the baffle 10 is located inside the second air outlet 102 .

[0085] A cover plate is also provided on the baffle 10 , and the cover plate is used to close the second air outlet 102 . The cover plate is configured to switch between a state of shielding the second air outlet 102 and a state of avoiding the second air outlet 102 .

[0086] The baffle 10 is also provided with a plurality of second air outlets 102. The second air outlets 102 are annular and arranged around the center of the baffle 10. The plurality of second air outlets 102 are arranged in sequence along the connection line between any point from the center of the baffle 10 to the edge of the baffle 10. The plurality of second air outlets 102 further disperse the air blown out through the baffle 10, so that the air blown out through the baffle 10 changes from the speed of drying hair to the speed of drying hair; the second air outlets 102 can be blocked. When the second air outlets 102 are blocked, the air is blown out from the first air outlet 100, and the relatively fast wind speed can dry the hair. When the second air outlets 102 are opened, the air is blown out jointly by the first air outlet 100 and the second air outlets 102, and the relatively slow wind speed can dry the hair or perform hot compress heating care on local parts of the body, etc., meeting the diverse needs of users.

[0087] According to some embodiments of the present application, optionally, as Figure 7 shown, the flow guiding assembly 12 is composed of a plurality of flow guiding sleeves 123 sleeved from inside to outside in sequence. Any two adjacent flow guiding sleeves 123 among the plurality of flow guiding sleeves 123 enclose a second flow channel 124 communicating with the second air outlet 102.

[0088] The plurality of second channels can correspond to the plurality of second air outlets 102 one by one. At this time, the number of the plurality of flow guiding sleeves 123 is one more than the number of the plurality of second air outlets 102.

[0089] The flow guiding assembly 12 is composed of a plurality of flow guiding sleeves 123 sleeved from inside to outside in sequence. Any two adjacent flow guiding sleeves 123 among the plurality of flow guiding sleeves 123 enclose a second flow channel 124 communicating with the second air outlet 102. The plurality of second flow channels 124 disperse and guide the air in the air cavity 112 to the second opening, so that the air can pass through the second air outlet 102 more smoothly, reducing the risk that the air in the air cavity 112 impacts the baffle 10 near the second air outlet 102 and generates noise, which affects the use experience of the air outlet structure 1 provided by the present application.

[0090] According to some embodiments of the present application, optionally, as Figure 7 shown, in the length direction of the first housing 11, the interval distance between the flow guiding sleeve 123 and the second mounting opening 111 gradually decreases from the outermost flow guiding sleeve 123 among the plurality of flow guiding sleeves 123 to the innermost flow guiding sleeve 123 among the plurality of flow guiding sleeves 123.

[0091] The interval dimension between any two adjacent flow guiding sleeves 123 among the plurality of flow guiding sleeves 123 can be the same.

[0092] The spacing distance between the flow guide sleeve 123 and the second mounting port 111 gradually decreases from the outermost flow guide sleeve 123 among the multiple flow guide sleeves 123 to the innermost flow guide sleeve 123 among the multiple flow guide sleeves 123. During the process of the air in the air cavity 112 moving from the direction of the second mounting port 111 towards the first mounting port 110, the wind speed gradually slows down. The innermost flow guide sleeve 123 among the multiple flow guide sleeves 123 is close to the second mounting port 111, that is, the air with the largest quantity and the fastest speed will first contact the opening of the innermost flow guide sleeve 123. Although the quantity of air is large, due to the relatively fast flow rate of the wind, the quantity of air that just enters the opening of this flow guide sleeve 123 will not be too much; the outermost flow guide sleeve 123 among the multiple flow guide sleeves 123 is far from the second mounting port 111, that is, the air with the least quantity and the slowest speed will finally contact the opening of the outermost flow guide sleeve 123. Although the quantity of air is small, due to the relatively slow flow rate of the wind, the quantity of air that just enters the opening of this flow guide sleeve 123 will be a little more. Through the distribution of the positions of the openings of the multiple flow guide sleeves 123, the quantity of air entering each second channel is made similar, so that the wind passing through the baffle 10 can be blown out more evenly, improving the user experience.

[0093] According to some embodiments of the present application, optionally, as Figures 1 to 7 shown, the present application provides an air outlet fan, which includes a second housing 2, the air outlet structure 1 as described above, and a power mechanism 3. The second housing 2 has a first air inlet end 20 and a first air outlet end 21; the air outlet structure 1 is inserted into the first air outlet end 21 of the second housing 2, and the first air outlet end 21 is flush with the baffle 10; the power mechanism 3 is arranged inside the second housing 2, and the power mechanism 3 is used to guide the fluid to move from the first air inlet end 20 to the first air outlet end 21; wherein, the first air inlet end 20 is provided with a plurality of through holes for air inlet.

[0094] The first air inlet end 20 is provided with an end plate, and the through holes for air inlet can be arranged on the end plate and / or the side wall of the first air inlet end 20.

[0095] The power structure may include an air pump and a flow guide pipe. The air pump is arranged inside the flow guide pipe, and the second mounting port 111 can be detachably connected to the flow guide pipe.

[0096] The first housing 11 is located inside the part of the first air outlet end 21 of the second housing 2, and the baffle 10 is connected to the inner wall of the second housing 2.

[0097] The air outlet structure 1 is inserted into the first air outlet end 21 of the second housing 2; the power mechanism 3 is arranged inside the second housing 2. Air enters the second housing 2 from the first air inlet end 20, and the power mechanism 3 guides the air to move from the first air inlet end 20 to the first air outlet end 21. The air enters the air outlet structure 1 through the second mounting opening 111 and then blows out through the first air outlet 100 and / or the second air outlet 102 on the baffle 10, which can meet the needs of human and pet sharing, and can also meet the needs of drying and caring for long or short hair.

[0098] According to some embodiments of the present application, optionally, as Figures 1 to 3 shown, the second housing 2 includes a first straight section 22, a second straight section 23 and a connecting section 24. The connecting section 24 connects the first straight section 22 and the second straight section 23. The first air outlet end 21 is located at the first straight section 22, and the first air inlet end 20 is located at the second straight section 23; the value range of the angle between the first straight section 22 and the second straight section 23 is 75° to 45°.

[0099] The second straight section 23 can be cylindrical, which is convenient for the user to hold.

[0100] The second housing 2 includes a first straight section 22, a second straight section 23 and a connecting section 24. The connecting section 24 connects the first straight section 22 and the second straight section 23, making the hair dryer provided by the present application as a whole triangular; the value range of the angle between the first straight section 22 and the second straight section 23 is 75° to 45°, so that when the user holds the second straight section 23, the first air outlet end 21 of the hair dryer can more easily reach the parts of a person or a pet that are blocked or difficult to reach, improving the convenience of the hair dryer provided by the present application.

[0101] According to some embodiments of the present application, optionally, as Figures 2 to 3 shown, the dimension of the first straight section 22 in its own length direction is the same as the dimension of the second straight section 23 in its own length direction; the end surface of the first air inlet end 20 is flush with the surface of the baffle 10 facing away from the air cavity 112.

[0102] The spacing distance between the first air inlet end 20 and the baffle 10 is similar to the dimension of the first straight section 22 in its own length direction and the dimension of the second straight section 23 in its own length direction.

[0103] The dimension of the first straight section 22 in its own length direction is the same as that of the second straight section 23 in its own length direction; the end face of the first air inlet end 20 is flush with the surface of the baffle 10 facing away from the air cavity 112. When the end face of the first air inlet end 20 is in contact with the ground or the working platform, the baffle 10 can also be in contact with the ground or the working platform. Thus, when the ground or the working platform is supported by the end face of the first air inlet end 20 and the surface of the baffle 10 facing away from the air cavity 112, the supporting device provided by the present application can be placed upright, which is easier to store and also convenient for the user to hold the first straight section 22 or the second straight section 23 to pick up the air blower provided by the present application.

[0104] According to some embodiments of the present application, optionally, it further includes a heating module, a sound - emitting module and a change - over switch. The change - over switch is used to control the heating module to switch between a first state and a second state; when the heating module is in the first state, the heating module heats the fluid located inside the second housing 2 to T1, and when the heating module is in the second state, the heating module heats the fluid located inside the second housing 2 to T2, where T1>T2; among them, when the change - over switch controls the heating module to switch from the first state to the second state, the sound - emitting module emits a prompt sound.

[0105] The prompt sound can be the barking of a pet (such as a dog bark, a cat meow, etc.), which can remind the user of the mode switch and is not likely to startle the pet easily.

[0106] T1 is the temperature for human use, and its value range is 50° - 90°.

[0107] T2 is the temperature for pet use, and its value range is 30° - 70°.

[0108] When the heating module is in the first state, the heating module heats the fluid located inside the second housing 2 to the temperature T1 suitable for human use. When the heating module is in the second state, the heating module heats the fluid located inside the second housing 2 to the temperature T2 suitable for pet use, which can timely switch the temperature according to the user's needs; when the change - over switch controls the heating module to switch from the first state to the second state, the sound - emitting module emits a prompt sound to remind the user of the mode switch, eliminating the trouble for the user to specifically confirm the state.

[0109] According to some embodiments of the present application, optionally, it further includes a plug. The power mechanism 3 is electrically connected to the plug through an electric wire. The plug includes a plug housing and a plug pin, and the plug housing is provided with a baffle perpendicular to the length direction of the plug pin.

[0110] The outer layer material of the electric wire uses a flexible material such as silicone to imitate the skin texture, reducing the risk of scaring the pet when the electric wire comes into contact with the pet.

[0111] The baffle can be folded to save the installation space.

[0112] Most of the hair dryers provided by this application are applied in relatively humid environments. A baffle perpendicular to the length direction of the pin is provided on the plug housing. When the plug is inserted into the power socket, the baffle can block the jacks near itself, avoiding the situation that the water generated during the drying process splashes into or flows along the wire into the jacks, causing safety accidents.

[0113] Although this application has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of this application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. This application is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
