[0017] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0018] When the existing dual-purpose cooling and heating circulation fan is used to adjust the cooling and heating converter, one adjustment method is a screw-type. This adjustment method cannot accurately control the adjustment accuracy, resulting in the adjusted cold air or hot air often being too cold or too hot. The overcooled or overheated air will be directly blown onto the user's body surface through the fan blades, such as Figure 1 As shown, whether the air is too cold or too hot, it will bring discomfort to the user and may even cause harm to the user.

[0019] In view of the problems existing in the prior art, an embodiment of the present invention provides a dual-purpose cooling and heating circulation fan, such as Figure 2As shown, the dual-purpose cooling and heating circulation fan comprises a motor cover 1 and a fan blade cover 3 which are interconnected. The right end of the motor cover 1 is a mesh structure, which allows air to enter the device; and an air duct 8 is arranged between the motor cover 1 and the fan blade cover 3, and the air duct 8 is used to suck air from the motor cover 1 into the fan blade cover 3; the fan blade cover 3 is provided with a front net 4 at one end away from the motor cover 1, and the front net 4 is used to play a protective role to avoid the risk of the fan blade 7 falling off; a cooling and heating converter 5 is arranged in the air duct 8, and the cooling and heating converter 5 is used for converting cold air and hot air. The cooling and heating converter 5 is connected to a screw-type adjustment knob. In one example, the forward rotation of the adjustment knob is used for adjusting the hot air, and the reverse rotation of the adjustment knob is used for adjusting the cold air; a driving motor 2 is arranged in the motor cover 1, The driving end of the driving motor 2 is fixedly connected with a connecting rod 6, and the free end of the connecting rod 6 extends through the air duct 8 into the fan blade cover 3 and is fixedly connected with the fan blade 7. The driving motor 2 works to rotate the fan blade 7 through the connecting rod 6, so that the cold air or hot air conditioned by the cold and hot converter 5 is blown out of the fan blade cover 3; a temperature control mechanism 9 is arranged in the air duct 8, and the temperature control mechanism 9 is arranged between the cold and hot converter 5 and the fan blade 7. When working, the temperature control mechanism 9 readjusts the temperature of the cold air or hot air conditioned by the cold and hot converter 5 to reach the standard temperature (the standard temperature can be understood as a heating or cooling temperature suitable for human skin, which is 26℃~28℃ in summer and 18℃~25℃ in winter, and the indoor comfortable temperature range is 18℃~26℃).

[0020] In one embodiment, if Figure 3 As shown, the temperature regulating mechanism 9 includes a temperature regulating box 911 fixedly arranged in the air duct 8, and the temperature regulating box 911 is used to seal the fan cover 3 and the fan blades 7, so as to ensure that the cold air or hot air after passing through the cold and warm converter 5 always passes through the temperature regulating box 911; an end of the temperature regulating box 911 close to the fan blades 7 (which can be understood as the left end) is fixedly plugged with an outlet pipe 91 connected to the inner cavity of the temperature regulating box 911, and the outlet pipe 91 is set to output the standard temperature adjusted by the temperature regulating mechanism 9; the temperature regulating box 911 is close to the cold and warm converter 5 An air inlet 93 communicating with the inner cavity of the temperature regulating box 911 is provided at one end (which can be understood as the right end), a temperature control component 94 is provided on the inner top wall of the temperature regulating box 911, and a plurality of heat-conducting nets 95 are provided on the temperature control component 94. The plurality of heat-conducting nets 95 are vertically and parallelly arranged in the temperature regulating box 911, and the lower ends of the heat-conducting nets 95 are fixedly connected to the inner bottom wall of the temperature regulating box 911, and a first sensor 92 is fixedly provided on the inner side wall of the temperature regulating box 911, and the first sensor 92 is arranged close to the air inlet 93.

[0021] During operation, the air inlet 93 is used to introduce the cold air or hot air processed by the cold-heat converter 5 into the temperature control box 911. The first sensor 92 collects the temperature signal of the cold air or hot air entering the temperature control box 911. When it is detected that the cold air or hot air is too cold or too hot, the temperature control component 94 will be controlled to adjust the overcooled or overheated cold air or hot air to the standard temperature. The temperature control component 94 adjusts the overcooled or overheated cold air or hot air through a plurality of heat conducting nets 95.

[0022] In one embodiment, if Figure 4 As shown, the temperature control assembly 94 includes a heat conducting plate 941 fixedly connected to a plurality of heat conducting nets 95, and the heat conducting plate 941 is directly connected to the heat conducting nets 95 for heat conduction; a fixed cylinder 942 is fixedly connected to the upper end surface of the heat conducting plate 941, and the fixed cylinder 942 is fixedly arranged on the inner top wall of the temperature regulating box 91, and a condenser 943 and a heater 944 are fixedly arranged in the fixed cylinder 942, and the output ends of the condenser 943 and the heater 944 are fixedly connected to the heat conducting plate 941. In this embodiment, the condenser 943 is arranged to cool down the overheated hot air to reach the standard temperature; the heater 944 is arranged to heat up the overcooled cold air to reach the standard temperature.

[0023] In one embodiment, if Figure 5 As shown, the temperature control component 94 also includes a control component 945, which controls the temperature control component 94 according to the temperature signal collected by the first sensor 92; the control component 945 includes a fixed ring 9451 fixedly arranged on the upper end surface of the heat conducting plate 941, and a rotating disk 9452 rotatably arranged in the fixed ring 9451, a third electrode contact sheet 9457 is fixedly arranged on the circumference of the rotating disk 9452, and a first electrode contact sheet 9455 and a second electrode contact sheet 9456 are relatively arranged on the inner side wall of the fixed ring 9451. Of course, in other embodiments, In the example, the first electrode contact 9455 and the second electrode contact 9456 can also be staggered; the third electrode contact 9457 is matched with the first electrode contact 9455 and the second electrode contact 9456, and the third electrode contact 9457 is arranged between the first electrode contact 9455 and the second electrode contact 9456, and a rotating rod 9453 is fixedly connected to the upper end surface of the rotating disk 9452, and the upper end of the rotating rod 9453 is fixedly connected to the driving end of the driving motor 9454, and the driving motor 9454 is fixedly set on the inner top wall of the fixed cylinder 942.

[0024] During operation, when the first sensor 92 collects an overheating temperature signal, the drive motor 9454 will be started. The drive motor 9454 will drive the rotating disk 9452 to rotate clockwise through the rotating rod 9453. The rotation of the rotating disk 9452 will drive the third electrode contact 9457 to move in the direction of the second electrode contact 9456. When the second electrode contact 9456 contacts the third electrode contact 9457, the series circuit is connected, and the condenser 943 starts to work, and the overheated hot air in the temperature control box 911 is cooled and regulated through the heat conduction plate 941 and the heat conduction network 95; conversely, when the first sensor 92 collects an overcooling temperature signal, the drive motor 9454 will drive the rotating disk 9452 to rotate counterclockwise, and the third electrode contact 9457 is brought into contact with the first electrode contact 9455 through the rotating disk 9452, and the heater 944 works to increase the temperature of the overcooled cold air in the temperature control box 911.

[0025] In one embodiment, if Figure 6 As shown, the temperature regulating mechanism 9 also includes a gathering component, and the gathering component is used to gather the dispersed air in the temperature regulating box 911, so that the cooling or heating regulation process can be performed more efficiently; the gathering component includes a first arc plate 96 fixedly arranged on the inner wall of the temperature regulating box 911, and a first air storage cavity 97 is formed between the first arc plate 96 and the inner wall of the temperature regulating box 911, and the first air storage cavity 97 is used to store cold air or hot air that has been processed by the temperature regulating mechanism 9 and reaches a standard temperature; the first air storage cavity 97 is communicated with the air outlet pipe 91, and the inner wall of the temperature regulating box 911 is fixedly connected with A second curved plate 98, a second air storage cavity 99 is formed between the second curved plate 98 and the inner wall of the temperature regulating box 911, the second air storage cavity 99 is interconnected with the air inlet 93, and the second air storage cavity 99 is used to store cold air or hot air processed by the cold-heat converter 5; a plurality of air collecting pipes 910 are fixedly plugged into the first curved plate 96 and the second curved plate 98, the number of the air collecting pipes 910 can be set to 3, 4 or more, and the air collecting pipes 910 are made of heat-conducting material; the air collecting pipes 910 are used to connect the first air storage cavity 97 and the second air storage cavity 99, and the air collecting pipes 910 are fixedly plugged into the heat-conducting network 95.

[0026] The setting of the air collecting pipe 910 in this embodiment is used to collect the air in the second air storage chamber 99 into the air collecting pipe 910, and transmit it to the first air storage chamber 97 after centralized cooling or heating treatment in the air collecting pipe 910. In this way, through the setting of the air collecting pipe 910, it is possible to avoid the air in the second air storage chamber 99 from being dispersed into the temperature control box 911, which is not conducive to the rapid adjustment of the air temperature. In this embodiment, the temperature control component 94 directly performs centralized treatment on the air in the air collecting pipe 910 through the heat conducting network 95. Since the density of air molecules in the air collecting pipe 910 is large, rapid heat transfer can be achieved, thereby achieving the effect of rapid temperature adjustment.

[0027] In order to achieve rapid and balanced temperature transfer in the gas collecting pipe 910, thereby achieving a faster temperature adjustment effect, in one embodiment, as Figure 7 and Figure 8 As shown, the dual-purpose cooling and heating circulation fan further includes a convergence and divergence regulating component 10, which is arranged in the collecting pipe 910. The number of the convergence and divergence regulating components 10 can be set to be several, specifically, it can be set to 1, 2, 3 or more. Figure 7 In the example, three convergence and dispersion adjustment components 10 are arranged in the air collecting pipe 910; the density of air molecules in the air collecting pipe 910 is large, and the distance between adjacent air molecules is short, which is beneficial to the rapid conduction of heat on the one hand, but on the other hand, it will cause the air molecules close to the central axis of the air collecting pipe 910 to be unable to directly contact the air collecting pipe 910, that is, the temperature control surface. This part of the air molecules can only achieve the temperature control process through the sequential conduction of the edge air molecules, which will invisibly reduce the heat conduction efficiency.

[0028] In order to solve the above problems, in one implementation, Figure 8 As shown, the convergence and dispersion regulation component 10 includes a heat-conducting block 103 fixedly plugged into the gas collecting pipe 910, the heat-conducting block 103 is fixedly connected to the heat-conducting net 95, and the heat-conducting block 103 is made of heat-conducting material; the convergence and dispersion regulation component 10 also includes a first temperature regulating net 101 and a second temperature regulating net 104 arranged in the gas collecting pipe 910, and the first temperature regulating net 101 and the second temperature regulating net 104 are both made of heat-conducting material; the ends of the first temperature regulating net 101 and the second temperature regulating net 104 are fixedly connected to the heat-conducting block 103, wherein the ends of the first temperature regulating net 101 and the second temperature regulating net 104 close to the cold and warm converter 5 respectively form a dispersion surface 102 and a gathering surface 105, wherein the first temperature regulating net 101 and the second temperature regulating net 104 form a rhombus structure.

[0029] The arrangement of the convergence and dispersion regulation component 10 in this embodiment is used, on the one hand, to increase the temperature regulation area of ​​the air in the air collecting pipe 910, and on the other hand, to directly and synchronously regulate the temperature of the air molecules at the central axis of the air collecting pipe 910 and the air molecules at the edge, thereby improving the temperature regulation efficiency. Specifically, when the air molecules in the air collecting pipe 910 move from right to left, they will first contact the first temperature regulation net 101. Under the action of the dispersion surface 102 of the first temperature regulation net 101, the air molecules will move to both sides along the direction of F1, which can increase the contact area between the air molecules and the first temperature regulation net 101, thereby accelerating the temperature regulation efficiency. In order to achieve a larger contact area, the first temperature regulation net 101 is a hollow cone structure, and the central axis of the cone coincides with the horizontal central axis of the air collecting pipe 910; through the first temperature regulation net 1 The air molecules of F2 will contact the second temperature regulating net 104. Under the guidance of the aggregation surface 105 on the second temperature regulating net 104, the air molecules move along F2 on the hollow cavity wall of the second temperature regulating net 104, which will increase the contact area between the air molecules and the temperature regulating surface, thereby further accelerating the temperature regulation efficiency. In this embodiment, through the arrangement of several aggregation and dispersion adjustment components 10, the temperature of the air entering the first air storage cavity 97 can reach the standard temperature. It is worth noting that the structure of the first temperature regulating net 101 is consistent with that of the second temperature regulating net 104.

[0030] In order to better monitor the air temperature in the first air storage chamber 97, in one embodiment, Fig. 9 As shown, the cooling and heating dual-purpose circulation fan also includes a second sensor 11 arranged in the outlet pipe 91, and the second sensor 11 is used to monitor the air temperature in the first air storage cavity 97 to ensure that the air temperature output from the outlet pipe 91 is within the standard temperature.

[0031] Of course, in one case, the air temperature output from the air outlet pipe 91 is not within the standard range. In order to ensure that the air temperature output to the outside of the device remains within the standard range, in one embodiment, as Fig.10As shown, the dual-purpose cooling and heating circulation fan also includes a blocking mechanism 12. The blocking mechanism 12 is used to block the outlet pipe 91 when the second sensor 11 detects that the air temperature output from the outlet pipe 91 is not within the standard temperature range, so as to prevent the air that is not within the standard temperature range from being output to the outside of the device; the blocking mechanism 12 includes an extension pipe 121 that is interconnected with the outlet pipe 91, and a blocking groove 122 is provided on the inner bottom wall of the extension pipe 121. A movable plug 122 is provided on the top plate of the extension pipe 121. A sealing plate 123 matching the sealing groove 122 is connected, a supporting plate 124 is fixedly connected to the upper end of the sealing plate 123, a first magnet block 125 is embedded on the lower end surface of the supporting plate 124, a first electromagnet 126 matching the first magnet block 125 is fixedly connected to the outer wall of the extension tube 121, a first limit support assembly 127 is fixedly connected to the lower end surface of the supporting plate 124, and the lower end of the first limit support assembly 127 is fixedly connected to the outer wall of the extension tube 121.

[0032] The blocking mechanism 12 in this embodiment is used to block the outlet pipe 91 to prevent the air that is not within the standard temperature range from being transmitted to the outside of the device; when working, when the second sensor 11 detects that the air temperature in the outlet pipe 91 is not within the standard range, it will control the first electromagnet 126 to be energized. The energization of the first electromagnet 126 will generate magnetism. Under the action of magnetic attraction, the blocking plate 123 will move downward through the first magnet block 125 and the supporting plate 124, and enter the blocking groove 122, thereby blocking the outlet pipe 91 to prevent the air that is not within the standard range from being output to the outside of the device. After the air temperature in the outlet pipe 91 is adjusted to the standard range, the second sensor 11 collects the standard temperature signal, controls the first electromagnet 126 to be powered off, and the blocking plate 123 is reset upward to open the outlet pipe 91, so that the air within the standard temperature is output to the outside of the device.

[0033] In one embodiment, if Fig.10 As shown, the first position-limiting support assembly 127 includes a first position-limiting support rod 1271, a first position-limiting support cylinder 1272 and a first position-limiting support spring 1273. The first position-limiting support rod 1271 is movably inserted in the first position-limiting support cylinder 1272. The first position-limiting support spring 1273 is wound outside the first position-limiting support rod 1271, and the two ends of the first position-limiting support spring 1273 are respectively fixedly connected to the side wall of the first position-limiting support rod 1271 and the outer side wall of the first position-limiting support cylinder 1272. The arrangement of the first position-limiting support assembly 127 in this example can not only play a guiding and supporting role for the movement of the support plate 124, but also provide a reset force for the reset movement of the support plate 124.

[0034] When the blocking mechanism 12 completes the blocking of the air outlet pipe 91, the air content in the temperature control box 911 will increase, so that the air passing through the cold and warm converter 5 will no longer enter the temperature control box 911, and thus more air cannot be conditioned. In order to solve the above problem, in one embodiment, Fig.11 As shown, the cooling and heating dual-purpose circulation fan also includes a suction mechanism 13, which includes a suction machine 131 arranged in the air inlet hole 93. Preferably, the suction machine 131 is fixed to the middle of the air inlet hole 93 in the vertical direction; a second electromagnet 132 is fixedly connected to the side wall of the suction machine 131, and a second magnet block 133 matched with the second electromagnet 132 is arranged in the air inlet hole 93. A first elastic plate 135 is fixedly connected to the side wall of the second magnet block 133. The first elastic plate 135 is fixedly connected to the side wall of the second magnet block 133. The free end of the elastic plate 135 is fixedly connected to the side wall of the air inlet hole 93, and a slide groove 134 is opened on the side wall of the air inlet hole 93 (the slide groove 134 is set on the top wall and the bottom wall of the air inlet hole 93), and the second magnet block 133 and the first elastic plate 135 are both slidably set in the slide groove 134; it is worth noting that the combined structure of the second electromagnet 132, the second magnet block 133, the slide groove 134 and the first elastic plate 135 is set into two groups, and the two groups of the combined structure are symmetrically arranged about the suction machine 131.

[0035] During operation, after the blocking mechanism 12 blocks the air outlet pipe 91, in order to allow the air on the right side of the air inlet 93 to continue to enter the left side, a suction machine 131 is provided in the present invention, which can draw the air on the right side of the air inlet 93 to the left side for temperature adjustment; in order to prevent the air drawn into the left side from escaping to the right side again, a combination structure of a second electromagnet 132, a second magnet block 133, a slide groove 134 and a first elastic plate 135 is provided in this embodiment, and the combination structure can block the other parts of the air inlet 93 except the part where the suction machine 131 is installed, thereby avoiding The air drawn into the left side escapes to the right side again. Specifically, when the second sensor 11 controls the first electromagnet 126 to start, on the one hand, the suction machine 131 is controlled to start, and the air on the right side of the air inlet 93 is drawn into the left side; on the other hand, the second electromagnet 132 is started and energized to generate magnetism. Under the action of magnetic attraction, the first elastic plate 135 is moved in the slide groove 134 by the second magnet block 133. When the second magnet block 133 contacts the second electromagnet 132, the air inlet 93 is blocked, thereby preventing the air drawn into the left side from escaping to the right side.

[0036] When the blocking mechanism 12 blocks the air outlet pipe 91, in order to extend the time for the temperature regulating mechanism 9 to regulate the air temperature, more air can be stored in the temperature regulating box 911 without being affected by the air pressure. In one embodiment, Fig.12As shown, the cooling and heating dual-purpose circulation fan also includes a telescopic mechanism 14, which includes a second position-limiting support assembly 141 disposed between the extension pipe 121 and the air outlet pipe 91 and used to connect the extension pipe 121 and the air outlet pipe 91, and a second elastic plate 142 having one end fixedly connected to the extension pipe 121 and the other end fixedly connected to the air outlet pipe 91, wherein the second elastic plate 142 is a tubular structure, and the second elastic plate 142 is covered outside the second position-limiting support assembly 141, The second position limiting support assembly 141 includes a second position limiting support rod 1411, a second position limiting support tube 1412 and a second position limiting support spring 1413. The second position limiting support rod 1411 is movably inserted in the second position limiting support tube 1412, and the second position limiting support spring 1413 is wound around the outside of the second position limiting support rod 1411, and the two ends of the second position limiting support spring 1413 are respectively fixedly connected to the side wall of the second position limiting support rod 1411 and the outer side wall of the second position limiting support tube 1412.

[0037] In this embodiment, the telescopic mechanism 14 is set to enable the extension tube 121 to move leftward relative to the exhaust pipe 91, thereby lengthening the overall length of the exhaust pipe 91 and the extension tube 121, and the extension tube 121 and the exhaust pipe 91 are sealed by the second elastic plate 142, so that the sealed cavity composed of the second elastic plate 142, the exhaust pipe 91 and the extension tube 121 continues to become larger, so that more control can be stored; wherein, the setting of the second limit support assembly 141 can not only play a guiding and supporting role for the movement of the extension tube 121, but also provide power for the resetting movement of the extension tube 121.
