An air outlet structure and an air outlet fan Technical Field
[0001] This application relates to the field of air outlet equipment technology, and more specifically, to an air outlet structure and an air outlet fan. Background Technology
[0002] Hair dryers, as an indispensable electrical appliance in modern households and personal care, are loved by many users for their efficiency and convenience. They primarily use a built-in motor to drive fan blades, drawing in ambient air and heating it through a heating element (for products with a hot air function), ultimately blowing out warm or cool airflow for quickly drying hair, styling hair, or increasing its shine and smoothness.
[0003] Conventional hair dryers typically produce a straight airflow, which is insufficient for larger, hairy pets (such as dogs and cats). This results in a longer drying time and uneven drying. Furthermore, the concentrated airflow can cause excessively high temperatures on a pet's sensitive fur, potentially damaging it or causing discomfort and anxiety. Therefore, conventional hair dryers are insufficient for users who want to dry or groom their pets' fur together. Summary of the Invention
[0004] The purpose of this application is to provide an air outlet structure and fan that can meet the needs of both humans and furry pets, thereby improving the aforementioned problems.
[0005] This application is achieved through the following technical solution:
[0006] In a first aspect, this application provides an air outlet structure, which includes a baffle, a first housing, and a flow guiding assembly. The baffle has a first air outlet, which is annular and surrounds the center of the baffle and is close to the edge of the baffle. The first housing is connected to the baffle and has a first mounting port and a second mounting port. The first mounting port is blocked by the baffle. The baffle and the first housing form an air cavity for accommodating fluid, and the first air outlet of the baffle is connected to the air cavity. The flow guiding assembly is located in the air cavity and connects the baffle and the first housing. The flow guiding assembly and the inner wall of the first housing form a first flow channel communicating with the first air outlet.
[0007] In the technical solution of this application embodiment, the first housing has a first mounting port and a second mounting port. The baffle and the first housing form a wind cavity for accommodating fluid. Air enters the wind cavity from the second mounting port and then moves to the first mounting port. The first air outlet of the baffle is connected to the ventilation cavity. The air in the wind cavity, after being blocked by the baffle, passes through the first air outlet. The first air outlet is annular, surrounding the center of the baffle and close to the edge of the baffle, allowing the air passing through the first air outlet to be blown out in a dispersed annular shape, increasing the coverage area of the air and improving the uniform drying effect on the whole body or long fur of furry pets. In addition, making the area affected by the air more dispersed allows the heat applied to the fur by the blown air to be more dispersed, reducing the discomfort or anxiety and stress reactions of pets caused by excessive local temperature due to hot air. Furthermore, the shape of the first air outlet, which makes the air outlet more dispersed, can also reduce the amount of air blown out. The wind intensity felt in the wind zone ensures that the air blower using the air outlet structure provided in this application produces a gentle breeze, reducing the risk of pets being startled by sudden strong winds and allowing users to dry and groom their pets' fur together. The airflow guide component is located in the air cavity, forming a first flow channel with the inner wall of the first housing, connecting to the first air outlet. This first flow channel disperses and guides the air in the air cavity to the first air outlet, reducing the impact of the wind on the baffle. On the one hand, this reduces the risk of the baffle being damaged under continuous pressure from the wind; on the other hand, it prevents the baffle from overheating due to continuous hot air impact, which could cause the baffle to come into contact with the user or pet's body, thus reducing the risk of the baffle overheating and improving the user comfort of the hair dryer using the air outlet structure provided in this application.
[0008] In some embodiments, the flow guiding component includes a first segment and a second segment, the first segment being connected to a baffle, the second segment being closer to the second mounting port than the first segment, and the dimension of the second segment in the height direction of the first housing gradually decreasing from the first mounting port to the second mounting port.
[0009] In the technical solution of this application embodiment, the air guiding component includes a first section and a second 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, allowing the air in the air cavity to be more easily guided into the first flow channel by the second section, reducing the residence time of the air in the air cavity, thereby reducing the internal pressure on the first housing during use, making the first housing less susceptible to damage due to internal pressure, and extending the service life of the first housing. The air velocity is inversely proportional to the width of the flow area, that is, the smaller the dimension of the first channel in the height direction of the first housing, the faster the air velocity through the first channel. 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, making the dimension of the first flow channel entry part larger and the dimension of other parts smaller, allowing the air to accelerate after entering the first flow channel, thereby increasing the speed at which the air in the air cavity is blown out of the first air outlet through the first flow channel, thereby making the air volume of the first air outlet larger, which can meet the needs of drying human or pet hair.
[0010] In some embodiments, the dimensions of the first housing in its height direction and / or the dimensions of the first housing in its width direction gradually decrease from the first mounting opening to the second mounting opening, and the outer wall of the first segment is parallel to the inner wall of the first housing.
[0011] In the technical solution of this application embodiment, the dimensions of the first housing in its height direction and / or the dimensions of the first housing in its width direction gradually decrease from the first mounting port to the second mounting port, making the size of the ring formed by the first air outlet larger. The air entering the air cavity from the second mounting port can diffuse and slow down along the first housing before being blown out through the first air outlet, reducing the wind force of the air blown out of the first air outlet and reducing the risk of pets being frightened by excessive wind force. The outer wall of the first section is parallel to the inner wall of the first housing, allowing the gas velocity in the part of the first flow channel between the first section and the first housing to move at a uniform speed, so that the air can be blown out from the first air outlet in a more uniform and gentle state, reducing the stimulation of the air outlet to the user or pet.
[0012] In some embodiments, the inner wall of the first air outlet is inclined toward 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 away from the air cavity to the side of the first air outlet facing the air cavity.
[0013] In the technical solution of this application embodiment, the inner wall of the first air outlet is inclined toward the center of the baffle. The inclination angle of each part of the first air outlet can be the same as the inclination angle of the corresponding part of the first flow channel, so that the air in the first flow channel can pass through the first air outlet more smoothly and blow out. The inclined first air outlet can make the wind blow towards the hair of people or pets, reducing the irritation caused by the wind directly impacting the skin when the wind direction is perpendicular to the skin surface, and improving the user comfort of the blower device using the air outlet structure provided in this application.
[0014] In some embodiments, the inner wall of the first air outlet is flush with the outer wall of the first segment.
[0015] In the technical solution of this application embodiment, 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 enter the first air outlet more smoothly and is not easily blocked by the baffle to generate noise, thereby reducing the decibel of the noise generated when the air outlet structure provided in this application is working, and making the noise generated when using the blower with the air outlet structure provided in this application less, so as not to frighten or cause discomfort to the pet.
[0016] In some embodiments, the dimension of the baffle in the width direction of the first housing is greater than the dimension of the baffle in the height direction of the first housing.
[0017] In the technical solution of this application embodiment, the dimension of the baffle in the width direction of the first housing is greater than the dimension of the baffle in the height direction of the first housing, thereby 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 human and pet hair, making the drying process more controllable and less likely to miss any areas.
[0018] In some embodiments, the first air outlet includes multiple inlet segments distributed around the center of the baffle. A first connecting portion is provided between any two adjacent inlet segments. The air guiding assembly is connected to the inner wall of the first housing through multiple first connecting plates, and the first connecting plates are connected to the first connecting portion.
[0019] In the technical solution of this application embodiment, a first connecting part is provided between any two adjacent outlet segments in a plurality of outlet segments to enhance the connection strength between the baffle located inside the annular first air outlet and the baffle located outside the first air outlet. The flow guiding component is connected to the inner wall of the first housing through a plurality of first connecting plates. The first connecting plates are connected to the first connecting part. The first connecting plates can enhance the strength of the first connecting part on the one hand, and shield the first connecting part on the other hand, reducing the risk of damage to the first connecting part caused by the heat and impact force brought by the air in the air cavity when passing through the outlet segment, thereby improving the service life of the first connecting part.
[0020] In some embodiments, the first connecting plate extends along the length of the first housing and does not exceed the flow guiding component.
[0021] In the technical solution of this application embodiment, the first connecting plate is along the length direction of the first housing, allowing the air in the air cavity to pass through the first flow channel in the shortest distance.
[0022] In some embodiments, the baffle is further provided with a plurality of second air outlets, the first air outlet being closer to the edge of the baffle than the second air outlet, the second air outlets being annular and arranged around the center of the baffle, and the plurality of second air outlets being arranged sequentially along a line connecting any point from the center of the baffle to the edge of the baffle.
[0023] In the technical solution of this application embodiment, the baffle is further provided with multiple second air outlets. The second air outlets are annular and arranged around the center of the baffle. The multiple second air outlets are arranged sequentially along the line connecting any point from the center of the baffle to any point on the edge of the baffle. The multiple second air outlets further disperse the air blown out through the baffle, so that the air blown out through the baffle changes from the speed of drying hair to the speed of drying hair. The second air outlets can be blocked. When the second air outlets are blocked, air is vented from the first air outlet. The faster air speed can dry the hair. When the second air outlets are opened, air is vented from both the first and second air outlets. The slower air speed can be used to dry the hair or to apply heat to the body for local heating care, etc., to meet the diverse needs of users.
[0024] In some embodiments, the flow guiding component is composed of a plurality of flow guiding sleeves arranged sequentially from the inside to the outside, and any two adjacent flow guiding sleeves among the plurality of flow guiding sleeves form a second flow channel that connects to the second air outlet.
[0025] In the technical solution of this application embodiment, the airflow guiding component is composed of multiple airflow guiding sleeves arranged sequentially from the inside to the outside. Any two adjacent airflow guiding sleeves form a second flow channel that connects to the second air outlet. The multiple second flow channels disperse and guide the air in the air cavity to the second opening, allowing the air to pass through the second air outlet more smoothly. This reduces the risk of the air in the air cavity impacting the baffle near the second air outlet and generating noise that affects the user experience of the air outlet structure provided by this application.
[0026] In some embodiments, in the length direction of the first housing, the distance between the guide sleeve and the second mounting port gradually decreases from the outermost guide sleeve to the innermost guide sleeve.
[0027] In the technical solution of this application embodiment, the distance between the guide sleeve and the second mounting port gradually decreases from the outermost guide sleeve to the innermost guide sleeve. As the air in the air cavity moves from the second mounting port towards the first mounting port, the wind speed gradually decreases. The innermost guide sleeve is closest to the second mounting port, meaning the largest and fastest airflow will contact the opening of the innermost guide sleeve first. Although the air volume is large, the high airflow speed ensures that the airflow is more efficient. The amount of air entering the opening of the guide sleeve is not too much; among the multiple guide sleeves, the outermost guide sleeve is the farthest from the second installation port, meaning that the smallest amount and slowest speed will eventually come into contact with the opening of the outermost guide sleeve. Although the amount of air is small, the slower airflow speed results in a larger amount of air entering the opening of the guide sleeve. By distributing the openings of the multiple guide sleeves, the amount of air entering each second channel is similar, allowing the airflow through the baffle to be blown out more evenly, thus improving the user experience.
[0028] Secondly, this application provides a blower, which includes a second housing, a first-aspect air outlet structure, 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 a baffle. The power mechanism is disposed inside the second housing and is used to guide fluid from the first air inlet end to the first air outlet end. The first air inlet end is provided with a plurality of through holes for air intake.
[0029] In the technical solution of this application embodiment, the air outlet structure is inserted into the first air outlet end of the second housing; the power mechanism is located inside the second housing. Air enters the second housing from the first air inlet end, and the power mechanism guides the air from the first air inlet end to the first air outlet end. The air enters the air outlet structure through the second mounting port, and is then blown out through the first air outlet and / or the second air outlet on the baffle. This can meet the needs of both humans and pets, and can also meet the needs of drying and caring for longer or shorter fur.
[0030] In some embodiments, the second housing includes a first straight section, a second straight section, and a connecting section, the connecting section connecting the first straight section and the second straight section, the first air outlet being located in the first straight section, and the first air inlet being located in the second straight section; the angle between the first straight section and the second straight section is in the range of 75° to 45°.
[0031] In the technical solution of this application embodiment, 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 this application triangular in shape. The angle between the first straight section and the second straight section is in the range of 75° to 45°, so that when the user holds the second straight section, the first air outlet of the blower can be easily extended to the parts of the person or pet that are blocked or difficult to reach, thus improving the convenience of the hair dryer provided by this application.
[0032] In some embodiments, the dimensions of the first straight section in its own length direction are the same as those of the second straight section in its own length direction; the end face of the first air inlet is flush with the surface of the baffle away from the air cavity.
[0033] In the technical solution of this application embodiment, the dimensions of the first straight section in its own length direction are the same as those of the second straight section in its own length direction; the end face of the first air inlet is flush with the surface of the baffle away from the air cavity, so that when the end face of the first air inlet is in contact with the ground or work platform, the baffle can also be in contact with the ground or work platform, thereby supporting the ground or work platform through the end face of the first air inlet and the surface of the baffle away from the air cavity, so that the support device provided by this application can be placed upright, making storage easier, and also making it convenient for users to grab the first straight section or the second straight section to pick up the air outlet provided by this application.
[0034] In some embodiments, the system further includes a heating module, a sound-emitting 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, it heats the fluid located inside the second housing to T1. When the heating module is in the second state, it heats the fluid located inside the second housing to T2, satisfying that T1 > T2. When the switching switch controls the heating module to switch from the first state to the second state, the sound-emitting module emits a prompt sound.
[0035] In the technical solution of this application embodiment, when the heating module is in the first state, the heating module heats the fluid located 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 located inside the second housing to a temperature T2 suitable for pet use. It can switch the temperature in a timely manner according to the user's needs. When the switch controls the heating module to switch from the first state to the second state, the sound module emits a prompt sound to remind the user that the mode has been switched, saving the user the trouble of specifically confirming the state.
[0036] In some embodiments, a plug is also included, and a power mechanism is electrically connected to the plug via a wire. The plug includes a plug housing and pins, and the plug housing is provided with a baffle plate perpendicular to the length direction of the pins.
[0037] In the technical solutions of this application, the hair dryer provided in this application is mostly used in relatively humid environments. The plug housing is provided with a baffle plate perpendicular to the length direction of the pin. When the plug is inserted into the power socket, the baffle plate can block the socket near itself to prevent water generated during the drying process from splashing onto or flowing along the wire into the socket and causing a safety accident.

[0054] According to some embodiments of this application, optionally, as shown in Figures 4 to 7, this 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 has a first air outlet 100, which is annular and 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 and has a first mounting port 110 and a second mounting port 111. The first mounting port 110 is blocked by the baffle 10. The baffle 10 and the first housing 11 form a wind cavity 112 for accommodating fluid. The first air outlet 100 of the baffle 10 is connected to the wind cavity 112. The flow guiding component 12 is located in the wind cavity 112 and connects the baffle 10 and the first housing 11. The flow guiding component 12 and the inner wall of the first housing 11 form a first flow channel 113 that communicates with the first air outlet 100.
[0055] The edge of the baffle 10 may 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, adhesive, or sleeve.
[0057] The shape of the first air outlet 100 can be the same as the shape formed by the edge of the baffle 10, so that the air outlets on the first baffle 10 are far from the center 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 or sealed to the baffle 10 to reduce the risk of air leakage between the two and improve the control effect on the flow direction of the air passing through the air cavity 112.
[0059] The fluid in this application is air.
[0060] The flow guide component 12 can be a hollow structure on the inside, which reduces the overall weight of the flow guide component 12 and makes it easier for users to handle; or, the flow guide component 12 can be a solid structure, which increases the strength of the flow guide component 12, reduces the risk of deformation of the flow guide component 12 under the influence of continuous blowing of high temperature wind, and increases the service life of the flow guide 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 form a ventilation cavity 112 for fluid passage. Air enters the ventilation 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 connected to the ventilation cavity 112. The air in the ventilation cavity 112 is blocked by the baffle 10 and then passes through the first air outlet 100. The first air outlet 100 is annular and surrounds the center of the baffle 10. Furthermore, the air outlet 100 is positioned near the edge of the baffle 10, allowing the airflow to be dispersed in a ring shape, increasing the coverage area and improving the even drying effect on the entire body or long fur of furry pets. Additionally, the dispersed airflow area allows the heat applied to the fur to be distributed more evenly, reducing discomfort or stress caused by localized overheating due to hot air. Moreover, the shape of the first air outlet 100 also helps to reduce... The airflow intensity felt in the small area being blown is reduced, resulting in a gentle breeze from the hair dryer using the air outlet structure 1 provided in this application. This reduces the risk of pets being startled by sudden strong winds, allowing users to dry and care for their pets' fur together. The airflow guide component 12 is located in the air cavity 112, and the airflow guide component 12 and the inner wall of the first housing 11 form a first flow channel 113 that connects to the first air outlet 100. The first flow channel 113 disperses and guides the air in the air cavity 112 to the first air outlet 100, reducing the impact of the wind on the baffle 10. On the one hand, this reduces the risk of the baffle 10 being damaged under the continuous pressure of the wind. On the other hand, it prevents the baffle 10 from overheating due to continuous hot air impact, which could cause the baffle 10 to come into contact with the user or pet's body. This reduces the risk of the baffle 10 overheating and improves the user comfort of the hair dryer using the air outlet structure 1 provided in this application.
[0062] According to some embodiments of this application, optionally, as shown in FIG5, the flow guiding component 12 includes a first segment 120 and a second segment 121. The first segment 120 is connected to the baffle 10. The second segment 121 is closer to the second mounting port 111 than the first segment 120. The dimension of the second segment 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 curved, so that the air blowing onto the second section 121 can be smoothly guided to the first flow channel 113 without impacting the second section 121 and generating noise, thereby reducing the noise emitted by the air outlet structure 1 provided in this application during use and reducing the risk of pets being frightened or becoming irritable by noise.
[0064] The airflow guiding component 12 includes a first section 120 and a second section 121. The dimension 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, allowing the air in the air cavity 112 to be more easily guided into the first flow channel 113 by the second section 121, reducing the residence time of the air in the air cavity 112, thereby reducing the internal pressure on the first housing 11 during use, making the first housing 11 less susceptible to damage due to internal pressure, and extending the service life of the first housing 11. The airflow velocity is inversely proportional to the width of the flow area, that is, the first channel in the first... The smaller the dimension of the housing 11 in the height direction, the faster the air speed through the first channel. The dimension 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, making the dimension of the part entering the first flow channel 113 larger and the dimension of the other parts smaller. This allows the air to accelerate after entering the first flow channel 113, thereby increasing the speed at which the air in the air cavity 112 is blown out of the first air outlet 100 through the first flow channel 113. This results in a larger air volume at the first air outlet 100, which can meet the needs of drying human or pet hair.
[0065] According to some embodiments of this application, optionally, as shown in Figures 5 and 7, the dimensions of the first housing 11 in its height direction and / or the dimensions of the first housing 11 in its width direction gradually decrease from the first mounting opening 110 to the second mounting opening 111, and the outer wall of the first segment 120 is parallel to the inner wall of the first housing 11.
[0066] The first housing 11 may be flared, with the first mounting port 110 being the wide opening of the first housing 11 and the second mounting port 111 being the narrow opening of the first housing 11.
[0067] The dimensions of the first housing 11 in its height direction and / or the dimensions of the first housing 11 in its width direction gradually decrease from the first mounting port 110 to the second mounting port 111, making the size of the ring formed by the first air outlet 100 larger. The air entering the air cavity 112 from the second mounting port 111 can diffuse and slow down along the first housing 11 before being blown out through the first air outlet 100. This reduces the wind force of the air blown out of the first air outlet 100, reducing the risk of pets being frightened by excessive wind force. The outer wall of the first section 120 is parallel to the inner wall of the first housing 11, allowing the gas velocity in the 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 more uniform and gentle state, reducing the stimulation of the airflow to the user or pet.
[0068] According to some embodiments of this application, optionally, as shown in Figures 5 and 7, the inner wall of the first air outlet 100 is inclined toward 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 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 is inclined toward the center of the baffle 10. 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, so that the air in the first flow channel 113 can pass through the first air outlet 100 and blow out more smoothly. The inclined first air outlet 100 can make the wind blow towards the hair of people or pets, reducing the irritation caused by the wind directly impacting the skin when the wind direction is perpendicular to the skin surface, and improving the comfort of using the blower with the air outlet structure 1 provided in this application.
[0071] According to some embodiments of this application, optionally, as shown in Figures 5 and 7, the inner wall of the first air outlet 100 is flush with the outer wall of the first segment 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, so that the air flowing through the first channel can enter the first air outlet 100 more smoothly and is not easily blocked by the baffle 10 to generate noise. This reduces the decibel of the noise generated when the air outlet structure 1 provided in this application is working, so that the noise generated when the blower using the air outlet structure 1 provided in this application is smaller, and it is less likely to frighten or cause discomfort to pets.
[0074] According to some embodiments of this application, optionally, as shown in Figures 4 and 6, the dimension of the baffle 10 in the width direction of the first housing 11 is greater than the dimension of the baffle 10 in the height direction of the first housing 11.
[0075] In some embodiments, the dimension of the baffle 10 in the width direction of the first housing 11 may be smaller than the dimension of the baffle 10 in the height direction of the first housing 11.
[0076] The dimension of the baffle 10 in the width direction of the first housing 11 is larger than the dimension of the baffle 10 in the height direction of the first housing 11, thereby increasing the coverage area of the air blown out by the first air outlet 100 in the width direction of the first housing 11, thus accelerating the drying speed of human or pet hair, making the drying process more controllable and less likely to miss any areas.
[0077] According to some embodiments of this application, optionally, as shown in Figures 4 and 6, the first air outlet 100 includes a plurality of outlet segments 1000, which are distributed around the center of the baffle 10. A first connecting portion 101 is provided between any two adjacent outlet 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 plates 122 are connected to the first connecting portion 101.
[0078] The number of multiple first connecting parts 101 is one less than the number of multiple segments 1000.
[0079] Each of the multiple first connecting parts 101 corresponds to one of the multiple first connecting plates 122.
[0080] A first connecting portion 101 is provided between any two adjacent outlet segments 1000 in the plurality of outlet segments 1000 to enhance the connection strength between the portion of baffle 10 located inside the annular first air outlet 100 and the portion of baffle 10 located outside the first air outlet 100. The flow guiding assembly 12 is connected to the inner wall of the first housing 11 through a plurality of first connecting plates 122. The first connecting plates 122 are connected to the first connecting portion 101. The first connecting plates 122 can enhance the strength of the first connecting portion 101 on the one hand, and shield the first connecting portion 101 on the other hand, reducing the risk of damage to the first connecting portion 101 caused by the heat and impact force brought by the air in the air cavity 112 passing through the outlet segment 1000, thereby improving the service life of the first connecting portion 101.
[0081] According to some embodiments of this application, optionally, as shown in Figures 5 and 7, the first connecting plate 122 extends along the length direction of the first housing 11 and does not exceed the flow guiding assembly 12.
[0082] The first connecting plate 122 runs along the length of the first housing 11, allowing the air in the air cavity 112 to pass through the first flow channel 113 in the shortest possible distance.
[0083] According to some embodiments of this application, optionally, as shown in Figures 6 and 7, the baffle 10 is further 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 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 sequentially along the line connecting any point from the center of the baffle 10 to the edge of the baffle 10.
[0084] Multiple second air outlets 102 are located on the innermost side. The second air outlet 102 can be a round hole or an irregular hole with 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] The baffle 10 is also provided with a cover plate, which is used to close the second air outlet 102. The cover plate is configured to switch between blocking the second air outlet 102 and avoiding the second air outlet 102.
[0086] The baffle 10 is also provided with multiple second air outlets 102. The second air outlets 102 are arranged in a ring around the center of the baffle 10. The multiple second air outlets 102 are arranged sequentially along the line connecting any point from the center of the baffle 10 to any point on the edge of the baffle 10. The multiple second air outlets 102 further disperse the air blown out by the baffle 10, so that the speed of the air blown out by the baffle 10 changes from drying the hair to drying the hair. The second air outlets 102 can be blocked. When the second air outlets 102 are blocked, the first air outlet 100 blows out the air. The faster air speed can dry the hair. When the second air outlets 102 are opened, the first air outlet 100 and the second air outlet 102 blow out the air together. The slower air speed can dry the hair or provide local heat therapy to the body, etc., to meet the diverse needs of users.
[0087] According to some embodiments of this application, optionally, as shown in FIG7, the flow guiding component 12 is composed of a plurality of flow guiding sleeves 123 arranged sequentially from the inside to the outside, and any two adjacent flow guiding sleeves 123 among the plurality of flow guiding sleeves 123 form a second flow channel 124 that connects to the second air outlet 102.
[0088] Multiple second channels can correspond one-to-one with multiple second air outlets 102. In this case, the number of multiple air guide sleeves 123 is one more than the number of multiple second air outlets 102.
[0089] The airflow guiding component 12 is composed of multiple airflow guiding sleeves 123 arranged sequentially from the inside to the outside. Any two adjacent airflow guiding sleeves 123 form a second flow channel 124 that connects to the second air outlet 102. The multiple second flow channels 124 disperse and guide the air in the air cavity 112 to the second opening, allowing the air to pass through the second air outlet 102 more smoothly. This reduces the risk that the air in the air cavity 112 will impact the baffle 10 near the second air outlet 102, generating noise that affects the user experience of the air outlet structure 1 provided in this application.
[0090] According to some embodiments of this application, optionally, as shown in FIG7, in the length direction of the first housing 11, the spacing between the guide sleeve 123 and the second mounting port 111 gradually decreases from the outermost guide sleeve 123 to the innermost guide sleeve 123 among the plurality of guide sleeves 123.
[0091] The spacing between any two adjacent guide sleeves 123 in the plurality of guide sleeves 123 can be the same.
[0092] The distance between the guide sleeve 123 and the second mounting port 111 gradually decreases from the outermost guide sleeve 123 to the innermost guide sleeve 123. As the air in the air cavity 112 moves from the second mounting port 111 towards the first mounting port 110, the wind speed gradually decreases. The innermost guide sleeve 123 is closest to the second mounting port 111, meaning the largest and fastest airflow will first contact the opening of the innermost guide sleeve 123. Although the volume of air is large, the high airflow speed makes... The amount of air entering the opening of the guide sleeve 123 is not too much; among the multiple guide sleeves 123, the outermost guide sleeve 123 is the farthest from the second mounting port 111, that is, the one with the least amount and the slowest speed will eventually come into contact with the opening of the outermost guide sleeve 123. Although the amount of air is small, the airflow speed is slow, so the amount of air entering the opening of the guide sleeve 123 will be more. By distributing the positions of the openings of the multiple guide sleeves 123, the amount of air entering each second channel is similar, so that the air passing through the baffle 10 can be blown out more evenly, improving the user experience.
[0093] According to some embodiments of this application, optionally, as shown in Figures 1 to 7, this application provides a blower, which includes a second housing 2, an 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 disposed inside the second housing 2, and the power mechanism 3 is used to guide fluid from the first air inlet end 20 to the first air outlet end 21. The first air inlet end 20 is provided with a plurality of through holes for air intake.
[0094] The first air inlet end 20 is provided with an end plate, and the through hole for air inlet can be provided 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 guide tube, with the air pump located inside the guide tube, and the second mounting port 111 being detachably connected to the guide tube.
[0096] The first housing 11 is located inside the first air outlet 21 portion 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 located 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 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 port 111, and is then blown out through the first air outlet 100 and / or the second air outlet 102 on the baffle 10. This can meet the needs of both humans and pets, and can also meet the needs of drying and caring for longer or shorter fur.
[0098] According to some embodiments of this application, optionally, as shown in Figures 1 to 3, 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 21 is located in the first straight section 22, and the first air inlet 20 is located in the second straight section 23. The angle between the first straight section 22 and the second straight section 23 is in the range of 75° to 45°.
[0099] The second straight section 23 can be cylindrical, making it easier for users 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 in this application triangular in shape. The angle between the first straight section 22 and the second straight section 23 is in the range of 75° to 45°, so that when the user holds the second straight section 23, the first air outlet 21 of the blower can be easily extended to the parts of the person or pet that are blocked or difficult to reach, thus improving the convenience of the hair dryer provided in this application.
[0101] According to some embodiments of this application, optionally, as shown in Figures 2-3, the dimensions of the first straight section 22 in its own length direction are the same as the dimensions of the second straight section 23 in its own length direction; the end face of the first air inlet 20 is flush with the surface of the baffle 10 away from the air cavity 112.
[0102] The distance between the first air inlet 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 dimensions of the first straight section 22 in its own length direction are the same as those 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 away from the air cavity 112, so that when the end face of the first air inlet end 20 is in contact with the ground or work platform, the baffle 10 can also be in contact with the ground or work platform. Thus, the end face of the first air inlet end 20 and the surface of the baffle 10 away from the air cavity 112 support the ground or work platform, allowing the support device provided by this application to be placed upright, making storage easier and facilitating the user to pick up the air outlet provided by this application by grasping the first straight section 22 or the second straight section 23.
[0104] According to some embodiments of this application, optionally, a heating module, a sound-emitting module, and a switching switch are also included. 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 located inside the second housing 2 to T1. When the heating module is in the second state, the heating module heats the fluid located inside the second housing 2 to T2, satisfying that T1 > T2. When the switching 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 alert sound can be a pet's bark (such as a dog bark or a cat meow), which can remind the user to switch modes without startling the pet.
[0106] T1 is the user temperature, with a value range of 50°~90°.
[0107] T2 is the temperature for pets, with a range of 30°C to 70°C.
[0108] When the heating module is in the first state, it heats the fluid inside the second housing 2 to a temperature T1 suitable for human use. When the heating module is in the second state, it heats the fluid inside the second housing 2 to a temperature T2 suitable for pets, allowing for timely temperature switching according to the user's needs. When the switch controls the heating module to switch from the first state to the second state, the sound module emits a prompt sound to alert the user that the mode has been switched, eliminating the need for the user to specifically confirm the status.
[0109] According to some embodiments of this application, optionally, a plug is also included. The power mechanism 3 is electrically connected to the plug via a wire. The plug includes a plug housing and pins. The plug housing is provided with a baffle plate perpendicular to the length direction of the pins.
[0110] The outer layer of the wire is made of flexible materials such as silicone to mimic the texture of skin, reducing the risk of startling pets when the wire comes into contact with them.
[0111] The cover can be folded up to save installation space.
[0112] The hair dryer provided in this application is mostly used in relatively humid environments. The plug housing is provided with a baffle plate perpendicular to the length direction of the pin. When the plug is inserted into the power socket, the baffle plate can block the socket near itself to prevent water generated during the drying process from splashing onto or flowing along the power cord into the socket and causing a safety accident.
[0113] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
