[0054] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0055] The arrows in the figure are used to indicate the direction of air flow. Figures 1 to 11As shown, the embodiment of the present disclosure provides an air supply device, which includes: a housing 10, a reciprocating motion assembly 30 and a one-way valve assembly 20, wherein the housing 10 defines a cavity 101 having a first air port 104 and a second air port 105; the reciprocating motion assembly 30 is movably disposed on the housing, and divides the cavity 101 into a first air cavity 102 and a second air cavity 103, and the reciprocating motion assembly 30 is used to change the volume of the first air cavity 102 and the second air cavity 103; the one-way valve assembly 20 is disposed at the first air port 104 and the second air port 105; 4 and the second air outlet 105, the one-way valve assembly 20 is used to make one of the first air outlet 104 and the second air outlet 105 for air intake and the other for air discharge; wherein the first air outlet 104 is connected with both the first air cavity 102 and the second air cavity 103, and the second air outlet 105 is connected with both the first air cavity 102 and the second air cavity 103, when the reciprocating motion assembly 30 moves, one of the first air cavity 102 and the second air cavity 103 discharges air, and the other of the first air cavity 102 and the second air cavity 103 takes in air.

[0056] By adopting the air supply device provided in the embodiment of the present disclosure, by defining a cavity 101 with a first air outlet 104 and a second air outlet 105 in a shell 10, air can flow into the cavity 101 from the first air outlet 104 and flow out of the cavity 101 from the second air outlet 105, or flow into the cavity 101 from the second air outlet 105 and flow out of the cavity 101 from the first air outlet 104. By setting a reciprocating motion component 30, the reciprocating motion component 30 can drive the air flow in the cavity 101. By setting a one-way valve component 20 and setting the one-way valve component 20 at the first air outlet 104 and the second air outlet 105, air can flow along the flow path of the first air outlet 104-cavity 101-second air outlet 105 or the flow path of the second air outlet 105-cavity 101-first air outlet 104, thereby realizing a fixed air flow direction.

[0057] Compared with the air outlet method in the related art, the present embodiment uses the reciprocating motion component 30 and the one-way valve component 20 to cooperate with the compression of the first air chamber 102 and the second air chamber to achieve air outlet. There is no need to set up structures such as motors and blades. It can avoid the centrifugal force generated by the high-speed rotating blades causing the air to be sent out to be strong, which makes the user uncomfortable. In other words, the air supply method of the present embodiment is more gentle, reduces the impact when it is directly blown to the human body, is closer to natural wind, and improves the user's experience. Secondly, the wind shear feeling can be avoided, and the noise can be effectively reduced. Thirdly, the installation space required for the air supply device can be effectively reduced, and the installation position is more flexible. In addition, the present embodiment can better adapt to the changes in air volume requirements, and the adjustment is more flexible, so that the air outlet of natural wind can be better simulated, allowing more sophisticated speed regulation and air volume control, and the air volume and wind pressure can be accurately adjusted according to actual needs. The reciprocating motion component 30 can generate airflows of different intensities and rhythms by changing the volume of the air chamber, so as to be closer to the variable characteristics of wind speed in nature, and can also reduce wind pressure fluctuations to a certain extent, and provide a more stable pressure output.

[0058] Optionally, the one-way valve assembly 20 includes: two Tesla valve units 200, one of the two Tesla valve units 200 is connected to the first air outlet 104, and the other is connected to the second air outlet 105, so that one of the first air outlet 104 and the second air outlet 105 is used for air intake and the other is used for air outlet.

[0059] The air supply device provided by the embodiment of the present disclosure is provided with a Tesla valve unit 200 at the first air outlet 104 and the second air outlet 105 respectively. The Tesla valve unit 200 has the function of forward conduction and reverse inhibition, and can make the outside air flow into the cavity 101 from one of the first air outlet 104 and the second air outlet 105, and flow out of the cavity 101 from the other of the first air outlet 104 and the second air outlet 105, so as to realize the air supply device to form a fixed flow air outlet path, and by providing the Tesla valve unit 200, compared with the effect of unidirectional conduction and reverse inhibition achieved by providing a movable part, that is, automatically opening and closing valves are provided at the first air outlet 104 and the second air outlet 105. Since the Tesla valve unit 200 is a fixed structure, the sealing effect can be guaranteed, and the situation that the gap exists when the movable part is sealed, resulting in poor air outlet effect, and the fixed structure is not easy to be damaged, which can improve the reliability of the air supply device. Secondly, the Tesla valve can automatically adjust the flow rate according to the speed and pressure of the air flow. When the wind speed or wind pressure changes, the Tesla valve can still maintain a good unidirectional conduction function, which helps to maintain stable air duct operation. Thirdly, compared with traditional one-way valves, Tesla valves do not have fast-opening and closing parts, so they may produce less noise during operation, while also reducing energy loss caused by resistance and improving energy efficiency. In addition, Tesla valves have a simple and compact structure, do not take up too much space, and can effectively reduce the size of the air supply device.

[0060] Specifically, there are two one-way valve assemblies 20 , one of which is disposed at the first air outlet 104 and the second air outlet 105 corresponding to the first air cavity 102 , and the other is disposed at the first air outlet 104 and the second air outlet 105 corresponding to the second air cavity 103 .

[0061] In this way, the flow paths of the first air cavity 102 and the second air cavity 103 can be made the same, or the flow paths of the first air cavity 102 and the second air cavity 103 can be made different.

[0062] Optionally, each Tesla valve unit 200 is provided with a reverse air inlet 201 and a reverse air outlet 202 , wherein the reverse air inlet 201 of one Tesla valve unit 200 is connected to the first air port 104 , and the reverse air outlet 202 of another Tesla valve unit 200 is connected to the second air port 105 .

[0063] By adopting the air supply device provided by the embodiment of the present disclosure, by connecting the reverse air inlet 201 of a Tesla valve unit 200 with the first air outlet 104, the outside air can flow into the Tesla valve unit 200 from the reverse air outlet 202 of the Tesla valve unit 200, and flow along the internal pipeline to the reverse air inlet 201 and flow into the first air outlet 104. When the air flows in the reverse direction, the Tesla valve unit 200 can suppress the reverse flow of the air, so that the air can flow in one direction from the first air outlet 104; The reverse air outlet 202 of another Tesla valve unit 200 is connected to the second air outlet 105. The air in the second air outlet 105 can flow into the Tesla valve unit 200 along the reverse air outlet 202 and flow along its internal pipeline to the reverse air inlet 201 and flow out of the Tesla valve unit 200 from the reverse air inlet 201. When the air flows in the reverse direction, the Tesla valve unit 200 can suppress the reverse flow of the air and realize the unidirectional outflow of the air from the second air outlet 105, thereby forming a flow path with a specified wind direction.

[0064] Optionally, the Tesla valve unit 200 includes a choke column 203, which divides the interior of the Tesla valve unit 200 into a first flow channel 204 and a second flow channel 205. The wall surface of the choke column 203 facing the first flow channel 204 is arc-shaped, and the wall surface of the choke column 203 facing the second flow channel 205 is straight.

[0065] In this way, by making the wall surface of the wind-blocking column 203 facing the first flow channel 204 arc-shaped and the wall surface of the wind-blocking column 203 facing the second flow channel 205 straight-line-shaped, the resistance at the intersection of the first flow channel 204 and the second flow channel 205 can be increased, thereby improving the reverse blocking ability of the Tesla valve unit 200. In addition, by providing the wind-blocking column 203, the vortex and turbulence phenomena when the airflow passes through can be effectively reduced, thereby reducing the noise and vibration generated thereby, and improving the quiet performance and stability of the entire air supply device.

[0066] Optionally, the cross section of the cavity 101 is circular, and the reverse air outlet 202 is arranged along the tangent direction of the first air outlet 104 of the cavity 101 , and / or the reverse air inlet 201 is arranged along the tangent direction of the second air outlet 105 of the cavity 101 .

[0067] The air supply device provided by the embodiment of the present disclosure is used in combination with Figure 2 and Figure 3As shown in , by arranging the reverse air outlet 202 along the tangent direction of the first air outlet 104 in the cavity 101, the air resistance of the reverse air outlet 202 flowing into the first air outlet 104 can be reduced, and when the air at the first air outlet 104 flows in reverse, the resistance of the air flowing out of the first air outlet 104 flowing along the reverse air outlet 202 to the first flow channel 204 can also be reduced, thereby improving the reverse blocking ability of the Tesla valve unit 200. Similarly, by arranging the reverse air inlet 201 along the tangent direction of the second air outlet 105 in the cavity 101, not only the air outlet distance can be increased, but also the reverse blocking ability of the Tesla valve unit 200 can be improved. And by setting the cavity 101 to be circular, on the one hand, the power loss of air flowing in the cavity 101 can be reduced, and the air outlet distance can be further improved. On the other hand, the design of the circular cavity 101 can maximize the use of space, and at the same time, the air outlet is opened along the tangential direction, which reduces the right-angle transition between the air outlet and the cavity 101, making the structure more compact and more suitable for installation in embedded or narrow spaces. By setting the reverse air outlet 202 and the reverse air inlet 201 along the tangential direction of the cavity 101, it helps the airflow to enter or leave the cavity 101 smoothly, reducing the vortex and turbulence generated by the airflow at the air outlet, thereby reducing wind resistance and noise and improving airflow efficiency. Secondly, the airflow can be guided to diffuse along the circumference of the cavity 101, promoting the uniform distribution of the airflow in the cavity 101, further improving the uniformity and comfort of the air supply, and also helping to reduce wind pressure loss. In addition, the wind flow can be made smoother when entering or leaving the cavity 101, reducing kinetic energy loss, thereby improving the energy utilization efficiency of the entire air supply device.

[0068] Optionally, a tangent direction where the first air outlet is located and a tangent direction where the second air outlet is located form a certain angle, and the angle is greater than 45 degrees and less than 180 degrees.

[0069] Preferably, the angle between the tangent direction of the first air outlet and the tangent direction of the second air outlet is 90 degrees.

[0070] In this way, the backflow of air can be avoided.

[0071] Optionally, the Tesla valve unit 200 includes a plurality of Tesla valve lines connected in series.

[0072] By using the air supply device provided by the embodiment of the present disclosure, by setting a plurality of Tesla valve pipelines in series, the reverse blocking capability of the Tesla valve unit 200 can be further improved, and the air supply efficiency of the air supply device can be ensured. In addition, the Tesla valve pipelines in series can form a step-by-step pressure reduction process, and each level of Tesla valve can share a part of the pressure regulation task, so that the air pressure change is more stable, avoiding the situation where a single Tesla valve is subjected to excessive pressure difference and causes performance degradation.

[0073] Optionally, the solenoid valve assembly 21 includes: a fixed magnet 211 and a moving magnet 212, the fixed magnet 211 is arranged at the first air outlet 104 or the second air outlet 105; the moving magnet 212 is movably connected to the fixed magnet 211, and the moving magnet 212 has a first position and a second position. When the moving magnet 212 is in the first position, the moving magnet 212 blocks the first air outlet 104 or the second air outlet 105; when the moving magnet 212 is in the second position, the moving magnet 212 opens the first air outlet 104 or the second air outlet 105, so as to switch between the first position and the second position under the control of the fixed magnet 211.

[0074] With the disclosed embodiment, the fixed magnet 211 is fixed and the moving magnet 212 can switch between the first position (closing the air outlet) and the second position (opening the air outlet) under the action of its magnetic field. The fast switching of the moving magnet 212 under the action of the magnetic field of the fixed magnet 211 can realize the instant opening and closing of the air outlet, with a fast response speed, reducing ineffective power consumption and improving air supply efficiency. Under the action of the magnetic field of the fixed magnet 211, the moving magnet 212 can only allow airflow to pass from one direction, realize the function of a one-way valve, ensure the correct wind direction, avoid airflow backflow, and maintain the normal operation of the system.

[0075] Optionally, the solenoid valve assembly 21 includes: a first solenoid valve group 213 and a second solenoid valve group, the first solenoid valve group 213 is arranged at the first air port 104 and the second air port 105 corresponding to the first air chamber 102, and the first solenoid valve group 213 is electrically connected to the reciprocating motion assembly 30, and is used to control the opening and closing of the first air port 104 and the second air port 105 corresponding to the first air chamber 102, and is configured that when the reciprocating motion assembly 30 compresses the first air chamber 102, the first solenoid valve group 213 closes the first air port 104 corresponding to the first air chamber 102 and opens the second air port 105 corresponding to the first air chamber 102, and when the reciprocating motion assembly 30 compresses the second air chamber 103, the first solenoid valve group 213 opens the first air chamber 104 and the second air port 105 corresponding to the first air chamber 102. The first solenoid valve group is arranged at the first air outlet 104 and the second air outlet 105 corresponding to the second air chamber 103, and the first solenoid valve group 213 is electrically connected to the reciprocating motion component 30, for controlling the opening and closing of the first air outlet 104 and the second air outlet 105 corresponding to the second air chamber 103, and is configured that when the reciprocating motion component 30 compresses the first air chamber 102, the second solenoid valve group opens the second air outlet 105 corresponding to the second air chamber 103 and closes the first air outlet 104 corresponding to the second air chamber 103, and when the reciprocating motion component 30 compresses the second air chamber 103, the second solenoid valve group closes the second air outlet 105.

[0076] In this way, by electrically connecting the electromagnetic valve group and the reciprocating motion component 30, the electromagnetic valve group and the reciprocating motion component 30 can work synchronously, and the air outlet state can be adjusted instantly according to the change of the air cavity volume, so as to realize the precise switching of the wind flow direction, and ensure that the wind can enter or flow out of the corresponding air cavity at the right time, so as to realize the fixed flow path of the first air outlet 104-cavity 101-second air outlet 105 or the fixed flow path of the second air outlet 105-cavity 101-first air outlet 104. By precisely controlling the opening and closing of the air outlet through the electromagnetic valve group, the loss of air flow in the switching process can be minimized, and the overall performance and air volume stability of the air supply device can be ensured.

[0077] Optionally, the first solenoid valve group 213 includes two first solenoid switches, which are respectively arranged corresponding to the first air cavity 102 ; the second solenoid valve group includes two second solenoid switches, which are respectively arranged corresponding to the first air cavity 102 and the second air cavity 103 .

[0078] It should be noted that the electromagnetic switch includes the above-mentioned fixed magnet 211 and moving magnet 212. The electromagnetic switch here is used to refer to the first electromagnetic switch and the second electromagnetic switch. That is, the first electromagnetic switch and the second electromagnetic switch have the same structure, and both the first electromagnetic switch and the second electromagnetic switch include the fixed magnet 211 and the moving magnet 212.

[0079] Optionally, the cross-section of the cavity 101 is circular, a first air duct 22 is formed between the first air outlet 104 and the cavity 101 , a second air duct 23 is provided between the second air outlet 105 and the cavity 101 , and both the first air duct 22 and the second air duct 23 are extended along the tangent direction of the cavity 101 .

[0080] In this way, by setting the cavity 101 to be circular, on the one hand, the power loss of air flowing in the cavity 101 can be reduced, and the air outlet distance can be further improved. On the other hand, the design of the circular cavity 101 can maximize the use of space. At the same time, the first air duct 22 and the second air duct 23 are arranged along the tangent direction of the cavity 101, which reduces the right-angle transition of air between the cavity 101 and the first air outlet 104 or the second air outlet 105, making the structure more compact and more suitable for installation in embedded or narrow spaces. By setting the first air duct 22 and the second air duct 23 along the tangent direction of the cavity 101, it helps the airflow to enter or leave the cavity 101 smoothly, reducing the vortex and turbulence generated by the airflow at the air outlet, thereby reducing wind resistance and noise and improving airflow efficiency. Secondly, the airflow can be guided to diffuse along the circumference of the cavity 101, promoting the uniform distribution of the airflow in the cavity 101, further improving the uniformity and comfort of air supply, and also helping to reduce wind pressure loss. In addition, the airflow can be made smoother when entering or leaving the cavity 101, reducing kinetic energy loss, thereby improving the energy utilization efficiency of the entire air supply device.

[0081] Combination Figure 8 and Fig. 9 As shown in , optionally, the first electromagnetic switch is arranged in the first air duct 22 , the second electromagnetic switch is arranged in the second air duct 23 , and the first electromagnetic switch and the second electromagnetic switch are arranged between the first air duct 22 and the second air duct 23 .

[0082] In this way, by arranging the first electromagnetic switch in the first air duct 22 and the second electromagnetic switch in the second air duct 23, the electromagnetic switch can control each air duct individually, can quickly respond to the changes of the reciprocating motion component 30, and timely adjust the opening and closing state of the air duct, so as to minimize the energy loss of the wind flow during the switching process, thereby improving the air supply efficiency. By arranging the first electromagnetic switch and the second electromagnetic switch between the first air duct 22 and the second air duct 23, the space layout inside the air supply device can be optimized, making the overall structure more compact, which is conducive to the miniaturization design of the device.

[0083] Optionally, in the middle of the reciprocating assembly cavity, the volume of the first air cavity is equal to the volume of the second air cavity.

[0084] This helps to achieve the mechanical balance of the reciprocating component during operation, reduce vibration and noise caused by eccentric loading, and improve the stability and reliability of equipment operation. Secondly, the air output of the first air cavity and the second air cavity can be basically consistent. Compared with the arrangement of arranging the reciprocating component on one side of the cavity, the air supply component can be evenly discharged, achieving the effect of constant air output.

[0085] Optionally, the reciprocating motion component 30 includes: a permanent magnet 31 and a coil 32, the permanent magnet 31 is movably disposed in the cavity 101, and divides the cavity 101 into a first wind cavity 102 and a second wind cavity 103; the coil 32 is disposed in the shell and the coil 32 is disposed around the permanent magnet 31, and the coil 32 is used to drive the permanent magnet 31 to reciprocate.

[0086] By adopting the air supply device provided by the embodiment of the present disclosure, by movably arranging the permanent magnet 31 in the cavity 101, when the permanent magnet 31 moves from the first air cavity 102 to the second air cavity 103, the volume of the first air cavity 102 can be increased and the volume of the second air cavity 103 can be reduced; when the permanent magnet 31 moves from the second air cavity 103 to the first air cavity 102, the volume of the second air cavity 103 can be increased and the volume of the first air cavity 102 can be reduced, providing power for the air flow in the corresponding air cavity, and realizing intermittent air discharge of the first air cavity 102 and the second air cavity 103. This method has high energy conversion efficiency, fast response speed of the permanent magnet 31, can accurately control the position and movement speed of the permanent magnet 31, and realizes precise regulation of the volume of the first air cavity 102 and the second air cavity 103. By setting the coil 32, a magnetic field can be generated when the coil 32 is energized, and the permanent magnet 31 moves in the cavity 101 under the action of the magnetic force of the magnetic field. By constantly changing the direction of the current in the coil 32, the permanent magnet 31 can be made to reciprocate. By using the coil 32 to drive the permanent magnet 31 to move to achieve reciprocating motion to change the volume of the first air cavity 102 and the second air cavity 103, the control accuracy of the air supply device can be improved, and by controlling the movement frequency of the permanent magnet 31, the wind blown out by the air supply device can be made close to natural wind, thereby improving the user experience. In addition, the electromagnetic drive technology allows the drive component to be made small and compact, which is conducive to the miniaturized design of the air supply device, and can also be highly integrated with other electronic control systems, which is conducive to the realization of intelligent and automated operation.

[0087] Optionally, the magnitude and direction of the current flowing through the coil 32 can be adjusted.

[0088] In this way, by controlling the magnitude of the current flowing through the coil 32, the magnetic field strength generated by the coil 32 can be controlled, thereby controlling the magnitude of the force exerted on the permanent magnet 31, thereby controlling the movement speed of the permanent magnet 31, and controlling the air outlet distance of the air supply device. The user can increase or decrease the air outlet distance of the air supply device. In addition, by adjusting the magnitude and direction of the current in the coil 32, the magnitude and direction of the electromagnetic force can be conveniently changed, thereby flexibly controlling the movement state of the permanent magnet 31, adapting to different air volume requirements, and realizing intelligent control of wind speed and wind pressure.

[0089] Optionally, combined Figure 1 , Fig.10 and Fig.11 As shown in , the shell can be annular or linear. It can be understood that the structural form of the shell is not unique and can be changed according to actual use requirements, and is not limited to the structural form disclosed in this application.

[0090] In this way, compared with a traditional fan in which a motor drives the blades to rotate and discharge air, this embodiment can flexibly set the structural shape of the shell according to the actual installation environment, which can effectively improve the adaptability of the air supply device.

[0091] Optionally, there are multiple reciprocating motion components, and the multiple reciprocating motion components are arranged in the shell along the extension direction of the shell to divide the cavity into multiple air outlet areas.

[0092] In this way, multiple reciprocating motion components can work independently or collaboratively to achieve precise control of the air volume and wind direction in different air outlet areas, enhancing the flexibility and adaptability of the equipment. Secondly, if one of the reciprocating motion components fails, it will not affect the operation of the air supply device, thereby improving the reliability of the air supply device.

[0093] Specifically, combined Fig.10 As shown in the figure, the shell is in a circular shape, and a mounting groove for mounting a reciprocating motion component 30 is defined on the shell. The number of the reciprocating motion components 30 is four, and the four reciprocating motion components 30 are evenly spaced along the shell, dividing the shell into four air outlet parts, wherein two non-adjacent air outlet parts discharge air at the same time, and the other two air outlet parts take in air at the same time.

[0094] In this way, when the air supply device discharges air, the middle cavity of the shell can form a negative pressure zone, which plays a role in guiding the air on the rear side of the shell to flow forward. The air volume and wind direction of each air outlet part can also be independently controlled as needed. When two non-adjacent air outlet parts discharge air at the same time, and the other two air outlet parts take in air at the same time, the air volume can be evenly distributed among different areas, which is beneficial to improving the efficiency and comfort of the entire air supply system. Secondly, the four reciprocating motion components 30 can be controlled independently, that is, the four reciprocating motion components 30 can be moved at the same time, or one or more of them can be moved at the same time. By setting four independent air outlet parts, it is possible to achieve multi-point simultaneous air supply or suction, meeting the air circulation needs in a larger range or more complex space.

[0095] It should be noted that the number of reciprocating motion components 30 can be two, three, five, etc. The number of reciprocating motion components 30 in this embodiment is not unique. The setting of four reciprocating motion components 30 in the above embodiment is only used as an illustrative example and does not constitute a limitation on the number of reciprocating motion components 30.

[0096] Optionally, the housing 10 includes a main housing 11 and a sub-housing 12 , and the sub-housing 12 is detachably connected to the main housing 11 ; wherein the permanent magnet 31 and the coil 32 are both disposed in the sub-housing 12 .

[0097] By adopting the air supply device provided by the embodiment of the present disclosure, by configuring the shell to be a sub-shell 12 and a main shell 11 that can be detachably connected, and arranging the permanent magnet 31 and the coil 32 in the sub-shell 12, the user can conveniently disassemble and replace the reciprocating motion component 30, thereby avoiding the situation in which the inner wall of the sub-shell 12 is worn out for too long a time and the air outlet effect of the air supply device is seriously affected, and the user is unable to replace and repair it.

[0098] Optionally, both ends of the sub-housing 12 are provided with limit blocks 121 , and the limit blocks 121 are used to limit the movement distance of the permanent magnet 31 .

[0099] The air supply device provided by the embodiment of the present disclosure is adopted, and by setting limit blocks 121 at both ends of the sub-shell 12, the limit blocks 121 can limit the movement distance of the permanent magnet 31, so as to prevent the permanent magnet 31 from moving to the point of being out of the magnetic field of the coil 32, resulting in the permanent magnet 31 being unable to reciprocate. The limit blocks 121 can accurately control the reciprocating distance of the permanent magnet 31, ensuring that each movement is within a preset range, thereby ensuring the accuracy of air volume regulation. In addition, ensuring that the permanent magnet 31 moves within a limited area can maintain the stability of the operation of the air supply device, and avoid problems such as unstable airflow or reduced air supply efficiency caused by the movement of the permanent magnet 31 beyond the expected range.

[0100] Optionally, the air supply device further includes: a sliding sleeve 40 , the sliding sleeve 40 is nested in the permanent magnet 31 , and the sliding sleeve 40 is used to reduce the wear between the permanent magnet 31 and the inner surface of the cavity 101 .

[0101] By adopting the air supply device provided by the embodiment of the present disclosure, by arranging the sliding sleeve 40 and arranging the sliding sleeve 40 nested permanent magnet 31, the wear of the inner surface of the permanent magnet 31 and the shell can be reduced, and the permanent magnet 31 and the shell can be protected, thereby effectively extending the service life of the air supply device. If the sliding sleeve 40 is worn, only the sliding sleeve 40 needs to be replaced, and the expensive permanent magnet 31 does not need to be replaced, thereby reducing the maintenance cost and difficulty. Secondly, through the lubrication of the sliding sleeve 40, the mechanical noise generated when the permanent magnet 31 moves can be reduced, so that the air supply device is quieter during operation. Thirdly, the sliding sleeve 40 can protect the permanent magnet 31 from dust, dirt and other impurities, and prevent the surface of the permanent magnet 31 from being damaged and affecting its magnetic field strength and performance. In addition, the sliding sleeve 40 can also help improve the sealing performance inside the cavity 101 to a certain extent, prevent gas leakage, and ensure the operating efficiency of the air supply device.

[0102] Specifically, the permanent magnet 31 is cylindrical, the sleeve 40 is annular, and the sleeve 40 is made of polytetrafluoroethylene. In this way, due to the advantages of polytetrafluoroethylene such as corrosion resistance, high temperature resistance, high lubricity and non-stick properties, the normal operation of the permanent magnet 31 can be ensured, thereby effectively extending the service life of the sleeve 40, and further extending the service life of the permanent magnet 31 and the cavity 101.

[0103] Optionally, the air supply device further includes: a coating, which is provided on the surface of the cavity 101 in contact with the permanent magnet 31 to reduce wear between the permanent magnet 31 and the inner surface of the cavity 101 .

[0104] By using the air supply device provided in the embodiment of the present disclosure, by providing a coating and providing the coating on the surface where the cavity 101 contacts the permanent magnet 31, the wear between the permanent magnet 31 and the inner surface of the shell can be reduced, thereby protecting the permanent magnet 31 and the shell, thereby effectively extending the service life of the air supply device.

[0105] Specifically, the coating may be a graphene coating.

[0106] In this way, the graphene coating has the characteristics of wear resistance and high temperature resistance, which can effectively extend the service life of the air supply device. Secondly, the heat generated by the permanent magnet 31 during operation can be dissipated in time to avoid the situation where the permanent magnet 31 overheats and causes performance degradation.

[0107] Optionally, the coating has good thermal conductivity.

[0108] In this way, the heat generated by the permanent magnet 31 during operation can be transferred to the cavity 101 in time, and then dissipated through the cavity 101 structure, thereby reducing the temperature of the permanent magnet 31 and avoiding demagnetization or performance degradation of the permanent magnet 31 due to long-term high-temperature operation. Secondly, the heat dissipation coating can reduce the thermal stress caused by the mismatch of thermal expansion between the permanent magnet 31 and the cavity 101 due to excessive temperature, and prevent deformation or cracking of components.

[0109] Optionally, the air supply device further includes: a heat sink, which is disposed on the shell and is used to dissipate heat generated when the permanent magnet 31 moves.

[0110] In this way, by providing a heat sink, the heat sink can dissipate the heat of the shell, increase the heat dissipation area of ​​the shell, and thus avoid overheating during movement that affects the stable operation of the air supply device.

[0111] Optionally, the air supply device further includes: a damper, which is arranged on the shell and is used to suppress vibration of the shell.

[0112] In this way, by arranging the damper and arranging the damper on the housing, the damper can reduce the noise generated by the resonance of the housing. Through the vibration reduction function of the damper, the precision components inside the air supply device, such as the permanent magnet 31 and the coil 32, can be effectively protected to avoid wear or damage caused by vibration.

[0113] Optionally, the air supply device further includes: a silencer structure 50, the silencer structure 50 is connected to the Tesla valve unit 200, and the silencer structure 50 is used to reduce wind noise.

[0114] By using the air supply device provided by the embodiment of the present disclosure, by providing a silencer structure 50 and connecting the silencer structure 50 to the Tesla valve unit 200, the silencer structure 50 can absorb and weaken the noise generated by the wind flow, thereby reducing the noise of the air supply device.

[0115] Optionally, the air supply device further includes: a noise reduction structure 50, which is connected to the first air duct 22 and / or the second air duct 23, and is used to reduce wind noise.

[0116] By using the air supply device provided by the embodiment of the present disclosure, by setting up a silencer structure 50 and connecting the silencer structure 50 to the first air duct 22 and / or the second air duct 23, the silencer structure 50 can absorb and weaken the noise generated by the wind flow, thereby reducing the noise of the air supply device.

[0117] Exemplarily, the muffler structure 50 is a Helmholtz muffler.

[0118] In this way, the Helmholtz silencer can effectively absorb noise within a specific frequency range through its internal resonance cavity structure. It is particularly good at dealing with medium and high frequency noise, and has a good suppressing effect on the wind noise generated by the air supply device. Secondly, by reasonably designing the chamber size and length of the Helmholtz silencer, a wider noise frequency range can be covered, thereby achieving effective control of the full-band wind noise of the air supply device. Thirdly, the Helmholtz silencer has a relatively simple structure and occupies a small space. It is suitable for situations where the internal space of the air supply device is limited and will not cause too much impact on the overall structural layout. In addition, the Helmholtz silencer can reduce the resistance to the airflow, thereby maintaining the air supply efficiency of the air supply device.

[0119] Specifically, combined Figure 2 and Figure 3 As shown in , the number of the muffler structures 50 is two, the two muffler structures 50 are respectively connected to the two Tesla valve units 200, and the two muffler structures 50 are adjacently arranged and disposed between the two Tesla valve units 200.

[0120] In this way, the space can be reasonably utilized and the installation space required for the air supply device can be reduced.

[0121] Optionally, the number of the muffler structures 50 may be four, and the four muffler structures 50 are respectively connected to the first flow channel 204 and the second flow channel 205 of the two Tesla valve units 200 .

[0122] In this way, by silencing each flow channel of the Tesla valve unit 200, precise silencing can be achieved to further reduce the noise of the air supply device.

[0123] Optionally, the housing 10, the Tesla valve unit 200 and the muffler structure 50 are integrally formed.

[0124] This makes it easier to produce and process, and improves the structural stability of the air supply device. In addition, the integrated design reduces seams and interfaces, reduces the possibility of air leakage, and improves the overall sealing and air supply efficiency.

[0125] Optionally, the muffler structure may be an expansion chamber muffler.

[0126] Optionally, the muffler structure 50 includes a muffler pipe 51 and a muffler chamber 52 , one end of the muffler pipe 51 is connected to the Tesla valve unit 200 , and the other end of the muffler pipe 51 is connected to the muffler chamber 52 .

[0127] The air supply device provided by the embodiment of the present disclosure is adopted, and the silencer pipe 51 and the silencer chamber 52 are provided. The silencer pipe 51 connects the Tesla valve unit 200 with the silencer chamber 52, and the silencer pipe 51 and the air in the silencer chamber 52 constitute an elastic resonance system. When the external noise is at the same frequency as the noise, resonance is generated, and the air in the silencer pipe 51 rubs against the pipe wall and consumes sound energy. The airflow first passes through the Tesla valve unit 200 and then enters the silencer pipe 51. The structural design inside the silencer pipe 51 can initially absorb and disperse part of the noise, and then the silencer chamber 52 performs deep noise reduction processing. This two-stage noise reduction structure is conducive to reducing wind noise more comprehensively and effectively. Secondly, the silencer pipe 51 and the silencer chamber 52 have different silencer mechanisms. The silencer pipe 51 is mainly for medium and high frequency noise, while the silencer chamber 52 processes low frequency noise through the chamber structure. The combination of the two can expand the silencer frequency band of the entire air supply device, thereby more effectively suppressing wind noise of various frequencies. Secondly, the silencer pipe 51 is tightly connected with the Tesla valve unit 200 and the silencer chamber 52, which can effectively utilize the limited space, realize a compact design, and facilitate installation inside the air supply device.

[0128] Optionally, the muffler pipe 51 is connected to the intersection of the first flow channel 204 and the second flow channel 205 of the Tesla valve unit 200 .

[0129] By using the air supply device provided by the embodiment of the present disclosure, by connecting the silencer pipe 51 to the intersection of the first flow channel 204 and the second flow channel 205 of the Tesla valve unit 200, when the Tesla valve unit 200 switches the wind direction, the airflow will produce a large flow rate change and pressure fluctuation at the intersection of the first flow channel 204 and the second flow channel 205. The silencer pipe 51 connected here can absorb and eliminate these noise sources in a targeted manner, thereby improving the noise reduction efficiency. The silencer structure 50 can not only eliminate wind noise, but also partially allow part of the air after the first flow channel 204 and the second flow channel 205 merge to flow into the silencer pipe 51, thereby inhibiting the outflow of air, further enhancing the air supply device's ability to inhibit wind outflow.

[0130] Optionally, the volume of the muffler chamber 52 may be adjustable.

[0131] In this way, by adjusting the volume of the silencer cavity 52 , the range of the silencer frequency of the silencer structure 50 can be increased to eliminate noise of different frequencies of the air supply device and improve the silencer effect of the silencer structure 50 .

[0132] Optionally, the diameter of the silencer pipe 51 can be flexibly set.

[0133] In this way, by adjusting the diameter of the silencer pipe 51, the range of the silencer frequency of the silencer structure 50 can be increased to eliminate noise of different frequencies of the air supply device and improve the silencer effect of the silencer structure 50. Specifically, by increasing the diameter of the silencer pipe 51, the height-to-diameter ratio can be reduced to eliminate higher frequency noise; conversely, by reducing the diameter of the silencer pipe 51, the height-to-diameter ratio can be increased to eliminate lower frequency noise.

[0134] Optionally, the air supply device further includes: honeycomb sound-absorbing cotton, which is filled in the muffler cavity 52 to reduce wind noise.

[0135] In this way, by filling the silencing cavity 52 with honeycomb sound-absorbing cotton, the tiny pores formed by the honeycomb structure can absorb noise without excessively hindering the passage of airflow, which helps to maintain the stability of air volume and wind pressure, and can reduce wind noise while reducing wind resistance.

[0136] Optionally, the air supply device further includes: sound-absorbing cotton, which is attached to the outer surface of the shell.

[0137] In this way, the sound-absorbing cotton can absorb and attenuate the noise generated inside the shell, especially the wind noise generated when high-speed airflow passes through the shell, significantly reducing the impact of noise on the external environment and providing a quieter operating environment. Secondly, the sound-absorbing cotton can also play a certain buffering and protective role, reducing the possibility of damage to the shell when it is impacted or bumped by external forces. In addition, the sound-absorbing cotton attached to the outer surface of the shell is relatively easy to install and replace, without the need to change the internal structure of the equipment, and the maintenance cost is relatively low.

[0138] Optionally, the shell includes a main shell 11 and a sub-shell 12, and the sub-shell 12 is detachably connected to the main shell 11; wherein the sub-shell 12 includes a first connecting structure 121 and a second connecting structure 122, the first connecting structure 121 is snap-connected to the sub-shell 12 and is detachably connected to the main shell 11; the second connecting structure 122 is snap-connected to the first connecting structure 121.

[0139] In this way, the main housing 11 and the sub-housing 12 are detachably connected, so that when the equipment needs maintenance, cleaning or replacement of parts, the operator can quickly and easily disassemble and assemble the housing, greatly improving the maintenance efficiency and convenience. The first connection structure 121 is snap-fitted with the sub-housing 12 and detachably connected with the main housing 11, and the second connection structure 122 is snap-fitted with the first connection structure 121. This layered connection ensures the stability of the housing after assembly and reduces the performance degradation or safety hazards of the equipment caused by loose housing connections.

[0140] Specifically, in the air supply device of this embodiment, the user energizes the coil 32, and the coil 32 generates a magnetic field. The permanent magnet 31 moves under the action of the interaction force of the magnetic field, and by continuously changing the direction of the current flowing through the coil 32, the magnetic pole position of the magnetic field can be changed, driving the permanent magnet 31 to reciprocate in the shell. When the permanent magnet 31 moves in the direction of increasing the volume of the first air cavity 102, the outside air flows in from the reverse air outlet 202 of the Tesla valve unit 200 connected to the first air outlet 104 and flows into the first air cavity 102 from the first air outlet 104, and the Tesla valve unit 200 at the second air outlet 105 blocks the air from flowing into the second air outlet 105; when the permanent magnet 31 moves in the direction of reducing the volume of the first air cavity 102, the Tesla valve unit 200 at the first air outlet 104 blocks the air from flowing into the second air outlet 105. The air flows out of the first air port 104, and the air in the first air cavity 102 flows into the Tesla valve unit 200 from the second air port 105. Since the permanent magnet 31 divides the cavity 101 into the first air cavity and the second air cavity, when the volume of the first air cavity 102 increases, the volume of the second air cavity 103 decreases. Similarly, at this time, the air in the second air cavity 103 flows out from the second air port 105. When the volume of the second air cavity 103 increases, the outside air flows into the second air cavity 103 from the first air port 104. In this way, intermittent air discharge of the air supply device can be achieved, and by adjusting the movement distance of the reciprocating motion component 30, that is, controlling the volume of the cavity 101 changed by a single movement of the permanent magnet 31, the wind force of the first air cavity 102 and the second air cavity 103 can be controlled.

[0141] It should be noted that the air outlet of the air supply device mentioned below can represent the first air outlet 104 or the second air outlet 105, and the air inlet of the air supply device mentioned below can represent the first air outlet 104 or the second air outlet 105. It can be understood that the first air outlet 104 and the second air outlet 105 as the air outlet are the air outlet of the air supply device, and the first air outlet 104 and the second air outlet 105 as the air inlet are the air inlet of the air supply device. Figure 8 and Fig. 9 As shown in , the air inlet of the air supply device represents the first air outlet 104 , and the air outlet of the air supply device represents the second air outlet 105 .

[0142] Combination Figures 12 to 26 As shown in , optionally, an embodiment of the present disclosure further provides an air conditioning device, including an air supply device as in any one of the above embodiments.

[0143] The air conditioning device provided by the embodiment of the present disclosure includes the air supply device of any one of the above embodiments, and thus has all the beneficial effects of the air supply device of any one of the above embodiments, which will not be described in detail here.

[0144] Optionally, the air conditioning device may be a fresh air blower, an air conditioner, or a fan. It is understandable that the specific structural form of the air conditioning device is not unique.

[0145] Combination Figure 12 to Figure 14 As shown in , the air conditioning device is provided with a cabinet 80 , and the cabinet 80 is provided with an air inlet 801 , an air outlet 802 and an air duct 803 , wherein an air supply device is provided at the air duct 803 , and the air supply device is used to control the air flow rate flowing from the air duct 803 into the cabinet 80 .

[0146] In this way, by arranging the air supply device at the air induced opening 803, the induced air volume of the air supply device can be actively controlled, and then the proportion of the induced air volume of the air outlet of the air conditioner can be actively adjusted.

[0147] Optionally, the air conditioning device also includes: a temperature detection device and a controller, the temperature detection device is arranged at the air outlet 802 of the cabinet 80, and is used to detect the outlet air temperature; the controller is electrically connected to the temperature detection device and the air supply device, and is used to adjust the air intake volume of the air supply device according to the outlet air temperature.

[0148] In this way, the controller can automatically adjust the induced air volume of the air supply device according to the outlet air temperature information fed back by the temperature detection device, thereby realizing precise control and intelligent adjustment of the outlet air temperature of the air conditioning device, and ensuring that the indoor temperature is always kept within an appropriate range. Specifically, when the outlet air temperature is too high or too low, the controller will increase or decrease the induced air volume of the air supply device accordingly to achieve the purpose of quickly adjusting the temperature, which not only improves the working efficiency of the air conditioning device, but also reduces unnecessary energy consumption. It can also reduce the discomfort caused by temperature fluctuations and improve the user experience.

[0149] Optionally, the air conditioning device further includes: an air induced baffle 83, which is arranged on the air supply device and is used to separate the two sides of the air supply device into two parts, wherein the air inlet and the air outlet of the air supply device are respectively located on both sides of the air induced baffle 83.

[0150] In this way, the air induced baffle 83 divides the internal space of the air supply device into two independent parts, so that one side of the air supply device serves as the air inlet area and the other side serves as the air outlet area, thereby realizing the orderly flow of air and avoiding the air flow flowing out of the air outlet from flowing back to the air inlet area to cause air flow short circuit, thereby affecting the air induced volume or causing part of the air to flow out from the inside of the air supply device to the outside.

[0151] Optionally, the air outlet of the air supply device is arranged toward the air outlet of the cabinet 80 .

[0152] In this way, it can be ensured that the airflow generated by the air supply device can flow out directly and effectively through the air outlet of the cabinet 80, thereby improving the efficiency of air volume transmission. Secondly, the wind resistance caused by the turning, expansion and contraction of the air duct can be minimized, so that the airflow is smooth, the wind energy loss is reduced, and the overall air supply performance is improved.

[0153] Combination Fig.17 and Fig.18 As shown in the figure, the embodiment of the present disclosure also provides a fresh air fan, which includes an air supply device 60 and a locking sleeve 61. The air supply device 60 is a ring structure; the locking sleeve 61 is nested on the outside of the air supply device 60 and is used to fix and install the air supply device 60; wherein the outer edge size of the locking sleeve 61 is greater than or equal to the outer edge size of the air supply device 60.

[0154] In this way, the retaining sleeve 61 is nested on the outside of the air supply device, which can provide stable support and firm fixation for the air supply device 60, preventing the air supply device from shifting or loosening due to vibration and other reasons during operation. The outer edge size of the retaining sleeve 61 is greater than or equal to the outer edge size of the air supply device 60, which can provide additional protection for the air supply device and prevent the air supply device from being bumped.

[0155] Specifically, the user can use the locking sleeve 61 to fix the fresh air fan on the wall or glass to facilitate installation and fixation.

[0156] Optionally, the locking sleeve 61 is made of elastic material.

[0157] In this way, the locking sleeve 61 can play a buffering role and improve the protection capability, and the locking sleeve 61 can fit tightly against the installation position, effectively filling the gap between the fresh air fan and the installation surface, enhancing the stability of the fresh air fan installation and reducing vibration and noise during operation.

[0158] Optionally, the locking sleeve 61 is made of a heat-insulating material.

[0159] In this way, the retaining sleeve 61 made of heat-insulating material can effectively prevent heat exchange between indoor and outdoor, reduce the cold bridge effect, and prevent temperature from being exchanged through the installation location of the fresh air fan, thereby reducing heat loss in winter and preventing heat intrusion in summer. Secondly, in cold seasons, the retaining sleeve 61 with good heat-insulating performance can reduce the temperature difference between the fresh air fan housing and the installation location, reduce the probability of condensation, protect the internal electrical components of the fresh air fan from moisture, and extend the service life of the equipment.

[0160] Specifically, the locking sleeve 61 may be made of polyurethane material.

[0161] Optionally, the fresh air fan also includes: a HEPA filter 62, which is connected to the air supply device and is located on the air inlet side of the air supply component, and is used to filter the air flowing through the HEPA filter; wherein the size of the HEPA filter is adapted to the inner edge size of the air supply device so that the HEPA filter covers the annular cavity of the air supply device.

[0162] In this way, the size of the HEPA filter 62 is matched with the inner edge size of the air supply device 60, ensuring that the filter can completely cover the annular cavity of the air supply device, achieving comprehensive filtration, preventing unfiltered air from directly entering the air supply device, and ensuring the maximum purification effect. Secondly, the size-matching design makes the air flow channel between the HEPA filter and the air supply device smooth, reducing the resistance when air passes through, helping to maintain the air volume and static pressure of the fresh air fan stable, and improving the overall ventilation efficiency.

[0163] Optionally, the fresh air fan also includes: an air inlet cover 63, which is arranged on the air inlet side of the air supply device, and the cover is arranged on one side of the HEPA filter and connected to the HEPA filter; wherein the air inlet cover 63 is provided with a plurality of openings, and the plurality of openings are evenly spaced.

[0164] In this way, the multiple openings on the air inlet cover 63 are evenly spaced, which helps air to enter the HEPA filter evenly from different directions, avoiding uneven airflow distribution that leads to reduced filtering effect or local blockage, and ensuring the high efficiency and stability of air filtration. Secondly, the air inlet cover 63 is connected to the HEPA filter. When replacing or cleaning the filter, the filter can be easily removed or replaced by operating the air inlet cover 63, which simplifies the maintenance steps and improves the convenience of user operation. Finally, the air inlet cover 63 can also prevent external objects from directly contacting the HEPA filter, reducing the possibility of the filter being damaged by foreign objects, and playing a role in protecting the HEPA filter.

[0165] Optionally, the air inlet cover 63 is detachably connected to the HEPA filter.

[0166] In this way, the detachable design allows the user to easily remove and install the air inlet cover 63 when the HEPA filter needs to be replaced or cleaned, without the need for professional tools or complicated operations, thereby greatly simplifying the maintenance procedure of the filter and improving the convenience of daily use.

[0167] Specifically, the outer edge of the HEPA filter is concave, the outer edge of the air inlet cover 63 is convex, and the air inlet cover 63 is engaged with the HEPA filter.

[0168] Optionally, the air supply device includes: a shell, provided with a first air outlet 104 and a second air outlet 105, one of the first air outlet 104 and the second air outlet 105 is used for air intake and the other is used for air outlet; the fresh air fan also includes: a fresh air partition 64, arranged in the shell to separate the two sides of the shell into an air inlet side and an air outlet side; wherein the first air outlet 104 and the second air outlet 105 are respectively located on both sides of the fresh air partition 64.

[0169] In this way, the existence of the fresh air partition 64 clarifies the air inlet and outlet channels, ensures that the air inlet and outlet air flows do not interfere with each other, ensures the orderly flow of the air flow inside the fresh air blower, and improves the air purification efficiency. By effectively separating the air inlet side and the air outlet side through the partition, it is possible to prevent the already purified air from mixing with the unpurified air, thereby avoiding re-pollution and improving the purification quality. Exemplarily, the air enters from the first air outlet 104 (air inlet), is filtered and purified by purification components such as the HEPA filter, and then is discharged from the second air outlet 105 (air outlet). In this way, the entire purification process is clear and definite, which is conducive to the efficient removal of pollutants.

[0170] Combination Figures 17 to 23 As shown in, optionally, an embodiment of the present disclosure further provides a fresh air air conditioner, comprising a fresh air fan as in any of the above embodiments.

[0171] The fresh air fan provided by the embodiments of the present disclosure includes the fresh air fan of any one of the above embodiments and thus has all the beneficial effects of the fresh air fan of any one of the above embodiments, which will not be described in detail here.

[0172] Optionally, the fresh air air conditioner includes: an indoor unit; a first end of the fresh air duct 65 is connected to the indoor unit, and the second end of the fresh air duct 65 is suitable for extending to the outdoors; wherein the fresh air fan is arranged in the fresh air duct 65, for driving outside air to flow into the indoor unit along the fresh air duct 65.

[0173] In this way, a fresh air duct 65 and a fresh air fan can be added to an air conditioner that does not have a fresh air module 66, so that it can have a fresh air function without large-scale modification of the existing air conditioner. By arranging the fresh air fan in the fresh air duct 65 instead of directly installing it inside the air conditioner, compared with the traditional fresh air air conditioner, there is no need to arrange the fresh air fan inside the air conditioner, which can effectively reduce the volume of the air conditioner. Secondly, the noise generated when the fresh air fan is running can be absorbed and attenuated by the duct wall of the fresh air duct 65, thereby reducing the noise level transmitted to the room and improving the comfort of the user. In addition, the fresh air fan is separately arranged in the fresh air duct 65, independent of the air conditioner body, and when it is necessary to clean, maintain or replace the fresh air fan, it is more convenient to operate and will not affect the normal use of other parts of the air conditioner.

[0174] The sealing of existing family rooms is getting better and better. The traditional one-way fresh air supply has good indoor sealing. After a period of time, as the indoor atmospheric pressure increases, the fresh air supply decreases, and the ventilation effect cannot be achieved. Therefore, a two-way fresh air air conditioner is proposed. The existing two-way fresh air air conditioner is often realized by setting an air inlet duct and an air outlet duct, and the fan is set in the air conditioner body to absorb the air around the air conditioner. There will be a situation where part of the air treated by the air conditioner is directly discharged from the room, affecting the efficiency of the air conditioner.

[0175] Optionally, the fresh air fan includes: the indoor unit has a fresh air module 66; the first end of the fresh air duct 67 is connected to the fresh air module 66, and the second end of the fresh air duct 67 is connected to the fresh air fan; wherein the fresh air fan is nested in the fresh air duct 67 and the fresh air fan is located on the outside of the fresh air duct 67, for driving the indoor air to flow out to the outside.

[0176] In this way, by nesting the fresh air fan in the fresh air duct 67 and locating the fresh air fan outside the fresh air duct 67, the air at the installation position of the fresh air fan can be driven to flow to the outside, which can effectively improve the fresh air efficiency of the fresh air air conditioner. In addition, the fresh air fan can dynamically adjust the exhaust volume according to the indoor pressure conditions, effectively solving the problem of gradually reducing the air supply volume due to the indoor airtightness, ensuring that the room continues to obtain sufficient fresh air and achieving efficient air exchange.

[0177] Specifically, the exhaust volume of the fresh air fan is smaller than the intake volume of the fresh air module 66 , and the exhaust volume of the fresh air fan is larger than half of the intake volume of the fresh air module 66 .

[0178] In this way, the exhaust volume of the fresh air fan is less than the intake volume of the fresh air module 66, so that the room can always maintain an appropriate positive pressure state, prevent external polluted air from penetrating into the room through the gaps, and avoid the phenomenon of stuffy air and hypoxia, which can improve the user experience. The exhaust volume exceeds half of the fresh air intake volume, indicating that there is enough fresh air in the room and an appropriate amount of old air is discharged, forming a good air circulation. In this way, harmful gases, moisture and odors in the room can be effectively removed, keeping the indoor air fresh.

[0179] Optionally, the indoor unit includes: a fresh air outlet duct 69, the fresh air outlet duct 69 has a first air outlet duct 691 and a second air outlet duct 692, the first air outlet duct 691 extends to the heat exchanger, and the second air outlet duct 692 extends to the outside of the indoor unit; a duct switching component 68, arranged in the fresh air outlet duct 69, for controlling the air in the fresh air outlet duct 69 to flow out along the first air outlet duct 691 or the second air outlet duct 692.

[0180] In this way, the first air outlet duct 691 extends to the heat exchanger, which means that the fresh air can be sent into the room after being processed (heated or cooled) by the heat exchanger to ensure the appropriate indoor temperature. The second air outlet duct 692 extends directly to the outside of the indoor unit, which may be used for natural air supply in a non-heating or cooling state, providing a more diverse air outlet mode. By setting the air duct switching component 68, the air outlet path of the fresh air can be freely switched, so that the treated fresh air can be sent into the room, or the untreated fresh air can be directly introduced when necessary, to achieve flexible and efficient air conditioning, and then the indoor air quality and temperature can be accurately controlled, so that users can enjoy a more comfortable and natural indoor environment.

[0181] Specifically, the indoor unit is provided with an exhaust port, and the second air outlet duct 692 extends to the exhaust port so that air can be exhausted from the indoor unit.

[0182] Optionally, the first end of the first air outlet duct 691 is connected to the first end of the second air outlet duct 692; the air duct switching assembly 68 includes: an air guide portion 682, rotatably disposed at the connection point between the first air outlet duct 691 and the second air outlet duct 692; a motor 681, used to drive the air guide portion 682 to rotate; wherein the air guide portion 682 has a first position and a second position, and the guide plate can switch between the first position and the second position under the drive of the motor 681 to control the air in the fresh air outlet duct 69 to flow out along the first air outlet duct 691 or the second air outlet duct 692.

[0183] In this way, the air guide part 682 can be driven to rotate by the motor 681, and the fresh air can be automatically or manually switched to flow out from the first air outlet duct 691 or the second air outlet duct 692 according to the indoor environment and user needs, thereby realizing intelligent control and flexible operation.

[0184] Specifically, when the air guide portion 682 is in the first position, the air guide portion 682 blocks the second air outlet duct 692 to allow air to flow out from the first air outlet duct 691 , and when the air guide portion 682 is in the second position, the air guide portion 682 blocks the first air outlet duct 691 to allow air to flow out from the second air outlet duct 692 .

[0185] In this way, the air guide part 682 can switch between the first position (guiding fresh air through the heat exchanger) and the second position (directly introducing untreated fresh air) under the drive of the motor 681, so that the first air outlet duct 691 is used when the temperature needs to be adjusted, and the second air outlet duct 692 is used when only fresh air needs to be introduced, effectively reducing energy consumption and improving energy efficiency.

[0186] Optionally, the fresh air air conditioner also includes: a detection device for detecting indoor temperature and outdoor temperature; a controller, which is electrically connected to the detection device and the air duct switching assembly 68, and is used to control the air guide part 682 to be in the first position or the second position according to the indoor and outdoor temperature difference.

[0187] In this way, based on the indoor and outdoor temperature difference data obtained by the detection device, the controller can intelligently determine the working mode of the fresh air air conditioner. Automated temperature detection and air duct switching ensure that the indoor environment is always maintained within a comfortable temperature range, avoiding excessively high or low temperatures, and improving the user's living or working comfort. Adjusting the fresh air processing method according to the actual temperature difference can avoid heating or cooling the fresh air when it is not necessary, reduce unnecessary energy consumption, improve the energy efficiency of the air conditioning system, and achieve energy-saving operation. The controller automatically controls the air duct switching, reducing the tediousness of manual intervention.

[0188] Specifically, when the temperature difference between the indoor temperature and the outdoor temperature is less than a preset value, the controller controls the air guide part 682 to be in the second position; when the temperature difference between the indoor temperature and the outdoor temperature is greater than or equal to the preset value, the controller controls the air guide part 682 to be in the first position.

[0189] In this way, the indoor and outdoor temperatures are automatically detected and compared, and the air duct switching component 68 is intelligently adjusted accordingly, which reflects the high degree of automation and intelligence of the air-conditioning system, does not require frequent manual intervention, and greatly improves the convenience of use.

[0190] Optionally, the preset value may be 3 degrees Celsius, 4 degrees Celsius, or 5 degrees Celsius. It is understood that the preset value is not unique.

[0191] Combination Figure 24 to Figure 26As shown in the embodiment of the present disclosure, there is also provided a bladeless fan, which includes: a base 70; a fan head 71 rotatably connected to the base 70, the fan head 71 includes an air distribution ring 72; an air supply device is arranged on the air distribution ring 72, and is used to drive air to flow from the rear side of the air distribution ring 72 toward the front side of the air distribution ring 72.

[0192] In this way, by arranging the air supply device on the air distribution ring 72, it is not necessary to arrange a fan inside the fan head 71 to drive the air flow. On the one hand, the air supply device can increase the air intake volume, and on the other hand, the air supply device can shorten the air duct distance, reduce wind loss, and increase the air outlet distance. By rotatably connecting the fan head 71 to the base 70, the air outlet direction of the air supply device can be changed, and multi-angle air supply can be achieved.

[0193] Optionally, there are multiple air supply devices, and the multiple air supply devices are evenly spaced along the air distribution ring 72; wherein each air supply device can independently discharge air.

[0194] In this way, multiple air supply devices can form a three-dimensional air supply effect in all directions and at multiple angles, so that the airflow covers the entire space more evenly, improves air circulation efficiency, and enhances comfort. Secondly, turning on some or all of the air supply devices according to actual needs avoids unnecessary energy waste, improves energy utilization efficiency, and is beneficial to energy conservation and environmental protection. In addition, compared with a single high-power fan, the independent operation of multiple small air supply devices can reduce the noise of a single device, making the entire fan quieter during operation.

[0195] Optionally, the fan head 71 is provided with an air inlet and an air outlet, the air inlet is located at the bottom of the fan head 71, and the air outlet is opened on the air distribution ring 72;

[0196] The bladeless fan also includes: a blower 73, which is arranged in the fan head 71, and is used to drive air to flow in from the air inlet and out from the air outlet; wherein, the air supply device 60 is arranged on the inner side of the air distribution ring 72, and the air supply device 60 discharges air in a controlled manner so that the air discharged by the air supply device 60 is mixed with the air discharged by the air distribution ring 72.

[0197] In this way, the airflow generated by the blower 73 is mixed with the air output of the air supply device 60, which can effectively improve the uniformity and diffusion effect of air mixing, making the blown airflow softer and covering a wider range. Secondly, the air supply device 60 can independently control the air output intensity and direction, thereby changing the size and direction of the mixed airflow. In addition, the combination of the blower 73 and the air supply device 60 can not only increase the air supply volume, but also reduce the loss of wind power during the transmission process, thereby improving the air supply efficiency and air output distance.

[0198] Optionally, the air distribution ring 72 is in a circular ring shape, and the shell of the air supply device 60 is adapted to the air distribution ring 72 .

[0199] In this way, the annular design helps the air to flow evenly from all angles, and combined with the air outlet of the air supply device 60, the air outlet airflow can be evenly dispersed under the guidance of the air distribution ring 72, providing a more comfortable wind feeling experience. Secondly, the annular design gives people a harmonious and smooth feeling visually, and the cooperation between the air supply device 60 shell and the air distribution ring 72 can increase the overall beauty and craftsmanship of the product.

[0200] Optionally, the air distribution ring 72 is square, and there are multiple air supply devices 60, the number of the multiple air supply devices 60 is equal to the number of sides of the air distribution ring 72, and the multiple air supply devices 60 are respectively arranged on each side.

[0201] In this way, the number of the plurality of air supply devices 60 is equal to the number of the sides of the air distribution ring 72, which means that each side has an air supply device 60. In this way, even air supply can be achieved on all four sides, increasing the air flow coverage area and enhancing the indoor air circulation effect. An air supply device 60 is independently arranged on each side of the air distribution ring 72, allowing the air volume and wind speed in each direction to be adjusted or controlled separately, further improving the flexibility of the air outlet of the bladeless fan.

[0202] Combination Fig.15 and Fig.16 As shown, the embodiment of the present disclosure also provides a vertical air conditioner, which includes: a cabinet 80 and an air supply device 60, the cabinet 80 is provided with an air inlet and an air outlet; the air supply device 60 is rotatably arranged at the air outlet, and is used to drive external air to flow into the cabinet 80 from the air inlet and flow out of the cabinet 80 from the air outlet.

[0203] In this way, by rotatably arranging the air supply device 60 at the air outlet, the angle and direction of the air supply can be adjusted, thereby realizing all-round and multi-angle air supply and ensuring more uniform indoor air circulation. Compared with the existing vertical cabinet, this embodiment does not need to set a guide plate to realize the change of the air outlet angle by rotating the guide plate, thereby avoiding the guide plate blocking the air outlet, thereby increasing the air outlet distance of the vertical air conditioner and realizing a wide range of long-distance air supply.

[0204] Optionally, the air supply device 60 is in the shape of an elongated strip, and there are multiple air supply devices 60 , and the multiple air supply devices 60 are all arranged to extend horizontally and / or vertically.

[0205] In this way, multiple air supply devices 60 are distributed inside the cabinet 80 and can extend horizontally or vertically, so that the air conditioner can achieve a more comprehensive and uniform air supply coverage area, effectively improving the indoor air circulation efficiency and cooling / heating effect. Each air supply device 60 can be controlled separately, and each air supply device 60 can flexibly adjust the air supply direction to achieve up and down, left and right multi-angle air supply.

[0206] Exemplary, combined Fig.15As shown in FIG, the plurality of air supply devices 60 are arranged vertically, and the plurality of air supply devices 60 are arranged evenly spaced laterally.

[0207] Optionally, the air supply device 60 is an annular structure, and the upper end and the lower end of the annular structure are rotatably connected to the cabinet 80.

[0208] In this way, the air supply device 60 of the ring structure can realize 360° all-round air supply, so that the air conditioner can evenly deliver the processed air to every corner of the room, thereby improving the indoor air circulation efficiency and the uniformity of temperature regulation. Secondly, compared with a single or several long strip air supply devices 60, the ring structure can increase the air supply area, reduce blind spots, and adjust the indoor temperature more quickly and effectively.

[0209] Optionally, the vertical air conditioner further includes: an air outlet guide plate 81, which is rotatably disposed at the air outlet of the air supply device 60 and is disposed around the air outlet of the air supply device 60, and is used to change the air outlet direction of the air supply device 60.

[0210] In this way, by rotatably arranging the air outlet guide plate 81 at the air outlet of the air supply device 60 and changing the angle of the air outlet guide plate 81, the air outlet direction of the air supply device 60 can be changed, thereby effectively optimizing the indoor air flow distribution, so that the hot and cold air delivered by the vertical air conditioner can circulate more evenly in the entire space, thereby improving the uniformity and comfort of indoor temperature regulation.

[0211] Specifically, the vertical air conditioner includes a motor, which is drivingly connected to the air outlet guide plate 81 and is used to drive the air outlet guide plate 81 to rotate relative to the air supply device 60.

[0212] In this way, the motor drives the air outlet guide plate 81 and the rotation angle of the air outlet guide plate 81 can be accurately controlled.

[0213] Optionally, there are multiple air outlet guide plates 81 , and the number of the air outlet guide plates 81 is equal to the number of the air supply devices 60 and is arranged in a one-to-one correspondence.

[0214] In this way, by providing the air outlet guide plate 81 and the air supply device 60 in a one-to-one correspondence, the air outlet direction of each air supply device 60 can be individually controlled. Fig.15 As shown in , the air supply devices 60 on both sides of the multiple air supply devices 60 can be tilted to discharge air toward the sides, and the middle air supply device 60 can discharge air forward, so as to achieve simultaneous large-scale air supply.

[0215] Optionally, the vertical air conditioner further includes: an elastic rubber strip, which is arranged between the air outlet guide plate 81 and the air outlet, and the elastic rubber strip is connected to the air outlet guide plate 81 and the cabinet 80, and is used to close the gap between the air outlet guide plate 81 and the air outlet.

[0216] In this way, by providing the elastic rubber strip, the elastic rubber strip can well fill the gap between the air outlet guide plate 81 and the air outlet, ensuring that the air outlet guide plate 81 still maintains good sealing performance when the guide plate rotates, and preventing air from escaping from the gap. The sealed gap can effectively reduce the wind noise generated when the air flows, and improve the quiet performance of the air conditioner.
