Technical Field
[0001] This application relates to the field of fan technology, and in particular to a temperature control device. Background Technology
[0002] In recent years, people have increasingly pursued a more convenient lifestyle. To meet the demand for fans during outdoor activities or other life scenarios, various portable fans, such as neck fans, have emerged on the market. The advent of neck fans has solved the limitations of handheld fans. Whether for sports, outdoor activities, or office use, neck fans can free up users' hands, providing a breeze anytime, anywhere without needing to hold them.
[0003] Traditional neck fans generate pre-swirl when the airflow enters the fan, creating turbulent airflow. When this turbulent airflow flows toward the fan blades, it impacts the fan blades and generates noise. Utility Model Content
[0004] This application provides a temperature control device.
[0005] This application provides a temperature regulating device, which includes a housing, a distribution mesh, and a fan. The housing has an air inlet and an air outlet. The distribution mesh is connected to the housing and covers the air inlet. The distribution mesh has multiple distribution holes, the total area of which is greater than or equal to 40% and less than or equal to 60% of the area of the air inlet. The diameter of the inscribed circle of the distribution holes is less than or equal to 1 mm. The fan is disposed inside the housing, with its air inlet connected to the air inlet and its air outlet connected to the air outlet.
[0006] In some optional examples, the mesh parameters of the splitting mesh are 20-80 mesh, and the standard is GB / T6005.
[0007] In some optional examples, the inlet diameter of the fan is less than or equal to 100 mm, and the diameter of the air inlet is less than or equal to the inlet diameter of the fan.
[0008] In some alternative examples, the housing has opposing inner and outer surfaces, the air inlet extends through the housing, and the diversion mesh is located on the side of the air inlet closer to the outer surface.
[0009] In some alternative examples, the housing includes a body and a support frame, with the air intake opening on the body, the support frame connected to the body and positioned at the air intake, and the diversion mesh stacked on the side of the support frame away from the fan.
[0010] In some alternative examples, the air intake extends through both the inner and outer surfaces, the wall thickness of the housing defines the length of the air intake, and a flow divider is embedded in the air intake, the thickness of which is less than the length of the air intake.
[0011] In some optional examples, the temperature control device also includes a mounting bracket through which the shunt mesh is connected to the housing.
[0012] In some alternative examples, the mounting component includes a pressure ring and a snap-fit part, with the diverter mesh disposed between the pressure ring and the housing. The snap-fit part is connected to the side of the pressure ring facing the housing, and the housing has a slot in which the snap-fit part is engaged.
[0013] In some alternative examples, the pressure ring has a mounting hole with a diameter smaller than that of the distribution mesh, the inner wall of the mounting hole is arc-shaped, and the diameter of the mounting hole increases from the fan to the outside of the housing.
[0014] In some optional examples, the number of air intakes is set to multiple, and the number of air distribution nets is also set to multiple, with each air distribution net corresponding to one of the multiple air intakes, and each air distribution net covering the corresponding air intake.
[0015] When the temperature regulating device provided in this application is in use, the fan draws in air through the intake port and blows cool air out through the outlet, directing it towards the wearer's skin to cool and lower the temperature. During intake, the airflow first passes through a dense diversion mesh, which cuts the airflow into multiple fine streams, reducing the intensity of turbulence. This controls the turbulent pulsation speed entering the housing and contacting the fan, relatively reducing the noise generated by turbulent flow impacting the fan blades, thus lowering the noise level during operation and improving the user experience. Simultaneously, the diversion mesh 30 reduces the risk of the user's hair being caught in the fan. Attached Figure Description

[0023] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in function. For example, the term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to"; "generally" means that those skilled in the art can solve the technical problem and basically achieve the technical effect within a certain margin of error.
[0024] Please see Figure 1 This application provides a temperature regulating device 100, which can be worn around the neck by a user to cool and lower the temperature, freeing the user's hands and achieving the effect of blowing air and cooling anytime and anywhere without holding it.
[0025] Please also refer to Figure 1 and Figure 2In this embodiment, the temperature control device 100 may include a housing 10, a distribution net 30, and a fan 50. The housing 10 defines a wearing space 101 for a user to wear, and an installation space 103 is provided inside the housing 10. The housing 10 has an air intake 105 and an air outlet 107 communicating with the installation space 103. The distribution net 30 is connected to the housing 10 and covers the air intake 105. The distribution net 30 has multiple distribution holes 32, the total area of which is greater than or equal to 40% and less than or equal to 60% of the area of the air intake 105, and the diameter of the inscribed circle of each distribution hole 32 is less than or equal to 1 mm. The fan 50 is disposed within the installation space 103, with its air inlet connected to the air intake 105 and its air outlet connected to the air outlet 107.
[0026] In use, the fan 50 draws in air through the intake port 105 and blows cool air out through the outlet 107, directing it towards the wearer's body surface to cool and lower the temperature. During intake, the airflow first passes through a dense distribution mesh 30, which cuts the airflow into multiple fine streams, reducing the intensity of turbulence. This controls the turbulent pulsation speed as it enters the housing 10 and contacts the fan 50, relatively reducing the noise generated by turbulent flow impacting the fan 50 blades. This lowers the noise level of the temperature control device 100 during operation and improves the user experience. The total area of the multiple distribution holes 32 is greater than or equal to 40% and less than or equal to 60% of the area of the intake port 105, ensuring the air intake efficiency of the temperature control device 100.
[0027] In this application, unless otherwise expressly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0028] When using the temperature regulating device 100, the user's neck is located within the wearing space 101. Specifically, the wearing space 101 has an opening on one side to facilitate wearing, and the overall shape of the housing 10 roughly conforms to the curvature of the user's neck to cool the user's body surface by wrapping around the neck. The housing 10 may include an outer shell 12 and an inner shell 14, with the inner shell 14 connected to the side of the outer shell 12 facing the wearing space 101. In this embodiment, the outer shell 12 is curved so that its two ends are spaced apart. The inner shell 14 may conform to the shape of the outer shell 12 and cover the entire side of the outer shell 12 facing the wearing space 101. The two ends of the inner shell 14 are respectively connected to the two ends of the outer shell 12, and the inner shell 14 defines the wearing space 101. In some embodiments, the thermal conductivity of the inner shell 14 may be higher than that of the outer shell 12, so that the portion of the housing 10 in contact with the user can efficiently transfer cold energy, improving cooling efficiency while reducing costs. For example, the inner shell 14 can be made of metal or ceramic materials with good thermal conductivity, or silicone filled with thermally conductive material to improve the skin-friendly feel of the temperature control device 100, and the outer shell 12 can be made of plastic, rubber or other materials.
[0029] The inner shell 14 has a contact surface 141 facing the wearing space 101 and a connecting surface 143 connected to the outer shell 12. Two connecting surfaces 143 are provided, one on each side of the contact surface 141 and one on each side of the outer shell 12. The two connecting surfaces 143 are spaced apart and intersect with the contact surface 141. An air intake 105 can be located on either the outer shell 12 or the inner shell 14. As an example, the air intake 105 can be located on the side of the inner shell 14 facing the wearing space 101, i.e., on the contact surface 141. An air outlet 107 can be located on the connecting surface 143 of the inner shell 14. When worn by the user, the air outlet 107 is located on the connecting surface 143 above the temperature control device 100. The connecting surface 143 is inclined towards the wearing space 101 so that the air blown from the air outlet 107 can be directed towards the user's body surface, such as the head and neck area.
[0030] The inner shell 14 is also curved to fit the shape of the outer shell 12, and both ends of the inner shell 14 are also curved to be spaced apart to wrap around the wearer's neck. There can be two air outlets 107, each located on a spaced-apart section of the inner shell 14. This specification does not limit the shape of the air outlets 107; they can be round or square. In this embodiment, the air outlet 107 is a strip-shaped vent extending along the curvature of the inner shell 14 to allow for a relatively large area of cool air to be blown out.
[0031] In some embodiments, the air outlet 107 may also be provided on the outer casing 12, or both the outer casing 12 and the inner casing 14 may be provided with air outlets 107; in other embodiments, the air outlet 107 may also be a gap between the outer casing 12 and the inner casing 14. The outer casing 12 may also be provided with structures such as heat dissipation vents.
[0032] In this embodiment, the fan 50 is disposed within the installation space 103 and located at the end of the housing 10. The air inlet side of the fan 50 is connected to the air intake 105. The fan 50 can be a centrifugal fan, with the airflow direction of the centrifugal fan being the axial direction and the airflow direction of the fan 50 being the radial direction. The air inlet side of the fan 50 can be directly connected to the air intake 105, or the air inlet side of the fan 50 can be connected to the air intake 105 through a connecting pipe. In this embodiment, the end face of the air outlet side of the fan 50 is approximately circular, and the air intake 105 is also a circular hole. The air outlet side of the fan 50 and the air intake 105 are arranged opposite to each other at intervals and are connected. The diameter of the air intake 105 is less than or equal to the diameter of the air outlet side of the fan 50, ensuring that the airflow entering the fan 50 is within the design capacity of the fan 50, which helps to control the direction of airflow, avoid uneven airflow and the generation of eddies, and maintain the stable operation of the fan 50. The fan 50 draws in air through the air inlet 105, and the airflow is blown out radially from the fan 50, flows inside the housing 10 and is blown out through the air outlet 107.
[0033] In some embodiments, the temperature control device 100 may further include a volute housing disposed within the installation space 103. The volute housing forms an air guide channel within the housing 10, and the air guide channel connects the air outlet side of the fan 50 and the air outlet 107 between the air inlet 105 and the air outlet 107. The fan 50 may be disposed within the volute housing, which surrounds the fan 50, gathers the air blown by the fan 50, and guides it to the air outlet 107 through the air guide channel, thereby relatively improving the cooling efficiency.
[0034] Please also refer to Figure 2 and Figure 3A flow divider 30 is disposed at the air intake 105 to cut the airflow entering the fan 50 and reduce turbulence intensity. The flow divider 30 covers the air intake 105, ensuring that the airflow must pass through it before entering the fan 50. The flow divider 30 may have multiple flow divider holes 32, which are evenly arranged. This specification does not limit the specific material of the flow divider 30; for example, it can be a plastic mesh or a metal mesh. In this embodiment, the flow divider 30 is made of woven metal wire. The metal wires are interwoven to form the aforementioned flow divider holes 32. Furthermore, the cross-section of the metal wire used in the flow divider 30 is circular, and the arc surface of the metal wire's peripheral wall makes the airflow smoother when entering the flow divider 30. On the other hand, the metal flow divider 30 also prevents hair from being sucked into the housing 10 when the user uses the temperature control device 100, greatly reducing the risk of hair being caught in the fan 50.
[0035] The mesh count of the flow divider 30 affects the suction efficiency and noise reduction effect of the temperature control device 100. The mesh count of the flow divider 30 refers to the number of openings per inch of the flow divider 30, used to indicate the pore density and particle size of the flow divider 30. The higher the mesh count, the more flow divider openings 32 there are in the flow divider 30, and the smaller the particle size; the lower the mesh count, the fewer flow divider openings 32 there are, and the larger the particle size. The current standard for the mesh can be based on the following standard: GB / T6005-2008 Basic dimensions of sieve openings for metal wire woven mesh, perforated plates and electroformed thin plates.
[0036] This specification does not limit the specific mesh parameters of the diversion mesh 30. The mesh parameters of the diversion mesh 30 can be adaptively adjusted according to the parameters of the fan 50 in the actual application scenario. In this embodiment, the diameter of the air inlet side of the fan 50 is less than or equal to 100mm, and the mesh parameters of the diversion mesh 30 are set to be greater than or equal to 20 mesh and less than or equal to 80 mesh. The diversion mesh 30 with a mesh size of 20 to 80 can reduce the impact on the suction efficiency of the temperature control device 100 while cutting the airflow and reducing noise. Among them, when the mesh size of the diversion mesh 30 is 40, the impact on the suction efficiency is minimal. When the mesh size of the diversion mesh 30 is 80, it can also cut the airflow and reduce noise, but the generated wind resistance is greater than that of the 40-mesh diversion mesh 30, and the impact on the suction efficiency is also greater than that of the 40-mesh diversion mesh 30. In some embodiments, the mesh count of the diversion mesh 30 is less than 80, and the total area of the multiple diversion holes 32 is greater than half the area of the air intake 105, so that the air intake 105 has a relatively large air intake range, ensuring air intake efficiency while reducing noise.
[0037] Please see Figure 4In this embodiment, the housing 10 has an inner surface 1012 and an outer surface 1014 facing away from each other. An air intake 105 penetrates the housing 10, and a flow divider 30 is located on the side of the air intake 105 closest to the outer surface 1014. The air intake 105 penetrates both the inner surface 1012 and the outer surface 1014, and the flow divider 30 is spaced from the air inlet side of the fan 50 via the air intake 105. A gap 1016 exists between the inner surface 1012 and the air inlet side of the fan 50 along the axial direction of the fan 50. The gap 1016 and the air intake 105 together form a buffer space. The airflow entering through the air intake 105 passes through the air intake 105 and the gap 1016 before reaching the fan 50. The gap 1016 and the air intake 105 provide more buffer areas for the airflow, which helps to reduce the resistance of airflow and makes it less susceptible to sudden pressure changes or collisions, making the airflow more uniform and reducing eddies and turbulence, thus making the air intake of the temperature control device 100 more stable and smooth.
[0038] As an example, if the air intake 105 is located on the inner shell 14 and extends through both the inner and outer surfaces of the inner shell 14, a flow divider 30 can be disposed on the outer surface of the inner shell 14, covering the air intake 105. The flow divider 30 and the air inlet side of the fan 50 are separated by the air intake 105 and the gap 1016. The airflow divided by the flow divider 30 enters the air intake 105 and the gap 1016, which buffer the airflow and reduce airflow resistance.
[0039] The wall thickness of the housing 10 (the distance between the inner surface 1012 and the outer surface 1014) defines the length of the air intake 105, and the diversion mesh 30 covers the side of the air intake 105 closest to the outer surface 1014. The thickness of the diversion mesh 30 is less than the length of the air intake 105, increasing the distance between the diversion mesh 30 and the air intake side of the fan 50, thus forming a certain air intake space between the diversion mesh 30 and the fan 50. The air intake space includes the aforementioned air intake 105 and the space between the end of the air intake 105 located on the inner surface of the inner housing 14 and the air intake side of the fan 50.
[0040] In the description of this application, it should be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "inside", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the purpose of simplifying the description of this application and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0041] Please also refer to Figure 2 and Figure 4The temperature control device 100 may further include a mounting member 70, through which the diversion mesh 30 is connected to the housing 10. This specification does not limit the specific structure of the mounting member 70; for example, the mounting member 70 may be a fastener such as a screw, or it may be a snap-fit structure. In this embodiment, the mounting member 70 may include a pressure ring 72 and a snap-fit part 74, with the diversion mesh 30 disposed between the pressure ring 72 and the housing 10. The snap-fit part 74 is connected to the side of the pressure ring 72 facing the housing 10, and the housing 10 has a slot 102, in which the snap-fit part 74 is engaged. During installation, the diversion mesh 30 is first placed on the housing 10, covering the air intake 105. Then, the pressure ring 72 is pressed onto the diversion mesh 30, aligning the snap-fit part 74 with the slot 102 and applying force to embed it into the slot 102, thus completing the installation of the diversion mesh 30. The diversion mesh 30 is fixed to the housing 10 by the mounting part 70, which ensures the stable installation of the mounting part 70 and reduces the possibility of the diversion mesh 30 shaking due to airflow oscillation during air intake.
[0042] The pressure ring 72 can be a circular ring with a circular mounting hole 721. The axis of the mounting hole 721 is parallel to the axis of the pressure ring 72, or the axis of the mounting hole 721 and the axis of the pressure ring 72 can be coaxial. A snap-fit part 74 is connected to one side of the pressure ring 72 and protrudes relative to the surface of the pressure ring 72. This specification does not limit the specific structure of the snap-fit part 74; it can be a wedge-shaped block with a certain elasticity, or it can be a limiting post that interferes with the slot 102. Multiple snap-fit parts 74 can be provided, evenly distributed along the circumference of the pressure ring 72, improving the installation stability of the pressure ring 72. Correspondingly, multiple slots 102 are also provided, surrounding the outer periphery of the air intake 105, with each slot 102 corresponding to one of the multiple snap-fit parts 74.
[0043] In this embodiment, the inner side of the pressure ring 72 can be rounded to improve airflow smoothness. Specifically, the diameter of the mounting hole 721 is smaller than the diameter of the diversion mesh 30, and the inner wall of the mounting hole 721 is arc-shaped. When longitudinally sectioned along the axis of the mounting hole 721, the cross-sectional profile of the inner wall surface of the mounting hole 721 is a circular arc curve. The diameter of the mounting hole 721 increases from the fan 50 to the outside of the housing 10. The arc-shaped inner wall of the mounting hole 721 acts as a guide, making it easier for air near the air intake 105 to enter the air intake and reducing noise generated by turbulence.
[0044] To prevent the diversion mesh 30 from falling into the housing 10 through the air intake 105, in some embodiments, the housing 10 may include a body 121 and a support frame 123. The air intake 105 is formed in the body 121, and the support frame 123 is connected to the body 121 and disposed at the air intake 105. The diversion mesh 30 is stacked on the side of the support frame 123 facing away from the fan 50. The support frame 123 is used to support the diversion mesh 30, preventing the diversion mesh 30 from falling into the housing 10 and improving the working stability of the temperature control device 100. To reduce the impact on the air intake efficiency, the support frame 123 may be configured as a perforated support.
[0045] Multiple air intakes 105 and multiple air distribution nets 30 are provided, with each air distribution net 30 corresponding to one of the multiple air intakes 105, covering the corresponding air intake 105. Multiple air intakes 105 ensure the air intake efficiency of the temperature control device 100, and multiple air distribution nets 30 ensure the overall noise reduction effect of the temperature control device 100. This manual does not limit the specific location or number of air intakes 105 on the housing 10. Air intakes 105 can be located on the outer shell 12 or the inner shell 14, or multiple air intakes 105 can be distributed on both the inner shell 14 and the outer shell 12. In this embodiment, the number of air intakes 105 can be four, with two air intakes 105 located on the side of the outer shell 12 away from the inner shell 14 and located at both ends of the outer shell 12 respectively; the other two air intakes 105 are located on the side of the inner shell 14 facing the wearable space 101 and located at both ends of the inner shell 14 respectively.
[0046] Correspondingly, multiple fans 50 are provided, with each fan 50 corresponding to a different air intake 105. In this embodiment, four fans 50 are provided, with two fans 50 located at both ends of the outer casing 12 and the other two fans 50 located at both ends of the inner casing 14. The air inlet side of each fan 50 is connected to the corresponding air intake 105.
[0047] The air intakes 105 and the fan 50 at both ends of the housing 10 are positioned in the same way. The following description uses the air intake 105 and fan 50 at one end of the housing 10 as an example. For ease of description, the air intake 105 located on the outer shell 12 at one end of the housing 10 is designated as the first air intake 1052, and the air intake 105 located on the inner shell 14 is designated as the second air intake 1054; the fan 50 located inside the outer shell 12 at one end of the housing 10 is designated as the first fan 52, and the fan 50 located inside the inner shell 14 is designated as the second fan 54. Both the first fan 52 and the second fan 54 are centrifugal fans, and the first fan 52 and the second fan 54 are coaxially arranged. The side of the first fan 52 facing away from the second fan 54 is the suction side, which is connected to the first air intake 1052. The side of the second fan 54 facing away from the first fan 52 is also the suction side, which is connected to the second air intake 1054. Multiple diversion nets 30 are correspondingly distributed across multiple air intakes 105.
[0048] In some embodiments, the temperature control device 100 may further include structures such as a cooling element and a heat dissipation element. For example, the cooling element may be disposed within the housing 10 and is used to output cooling capacity. The cooling element may be disposed between the air intake 105 and the air outlet 107 to cool the airflow, thereby lowering the temperature of the airflow blown out through the air outlet 107 and improving the cooling effect.
[0049] When the temperature regulating device 100 provided in this embodiment is in use, the fan 50 draws in air through the air intake 105 and blows out cool air through the air outlet 107, which is then directed towards the wearer's body surface to cool and lower the temperature. During air intake, the airflow first passes through a dense diversion net 30, which cuts the airflow into multiple fine streams, reducing the intensity of turbulence. This controls the turbulent pulsation speed as it enters the housing 10 and contacts the fan 50, thereby reducing the noise generated by turbulent flow impacting the fan 50 blades. This lowers the noise level of the temperature regulating device 100 during use and improves the user experience. Simultaneously, the diversion net 30 reduces the risk of the user's hair being caught in the fan 50.
