Description

Technical Field

[0001] The utility model belongs to the technical field of fans, and in particular relates to a fan with an automatic adjustment function. Background Art

[0002] A fan is a driven fluid machine that relies on input mechanical energy to increase gas pressure and discharge the gas. Fans also play a vital role in waste incineration, supplying the necessary oxygen by introducing the appropriate amount of air into the incinerator.

In fact, the practical new heating wire has a mesh structure, so that the heat generated by the heating wire can be evenly blown into the incinerator by the motor, thereby preheating some wet items and making the items drier. When incinerating, the generated particulate matter and smoke can be greatly reduced, reducing pollution to the environment and avoiding the blockage of the ventilation pipe. At the same time, the direction of the heating wire can be adjusted by rotating the rod to reduce wind resistance and increase practicality.

[0004] Although the above solution can preheat the incineration material through the heating wire during use, the air volume provided by the heating wire cannot be automatically increased due to the resistance of the heating wire, which in turn affects the use effect of the fan and the oxygen supply in the incinerator. In addition, after long-term use, impurities attached to the surface of the heating wire will affect the heating effect. Utility Model Content

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0023] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The present invention provides a fan with automatic adjustment function. Figure 1-5 As shown, the fan with automatic adjustment function includes: a shell 1, a bracket 2 is fixedly mounted on the bottom inner wall of the shell 1, a first motor 3 is fixedly mounted on the bracket 2, and a fan blade is fixedly mounted on the output shaft of the first motor 3; a mounting shell 4 is fixedly mounted on the shell 1, and slide grooves are provided on the inner walls on both sides of the mounting shell 4; a limit rod 5 is fixedly mounted on the top inner wall of the mounting shell 4, and a limit block 6 is slidably mounted on the limit rod 5; a heating wire 7 is fixedly mounted on the limit block 6; a first conductive copper sheet 8 is fixedly mounted on the top of the heating wire 7; a second conductive copper sheet 9 is fixedly mounted on the top inner wall of the mounting shell 4; a moving mechanism for retracting the heating wire 7 is mounted on the mounting shell 4; and two cleaning mechanisms are mounted on the mounting shell 4 for cleaning the heating wire 7.

[0025] In this embodiment, when in use, the first motor 3 drives the fan blades to rotate, so that the external gas enters from the air inlet net 21, and then the gas is heated by the heating wire 7 and discharged from the air outlet net 22. Since the gas is heated, the incineration material in the incinerator can be heated in advance. Since the heating wire 7 will produce a certain wind resistance, the power consumption of the first motor 3 is relatively large at this time. When the weather temperature is high and the heating wire 7 is not needed, the moving mechanism can be used to store the heating wire 7 in the installation shell 4. When the heating wire 7 is stored in the installation shell 4, the first conductive copper sheet 8 on its top will contact the second conductive copper sheet 9, releasing the heat. After that, the controller 19 will automatically reduce the power of the first motor 3, thereby reducing the air volume provided by the fan. Conversely, when the heating wire 7 needs to be used, the moving mechanism is used to move the heating wire 7 into the shell 1, and the first conductive copper sheet 8 on the top thereof will be separated from the second conductive copper sheet 9. After separation, the controller 19 will automatically increase the power of the first motor 3 under the setting, thereby increasing the fan blade speed and increasing the air supply volume. The adjustment is more convenient. When the heating wire 7 is located in the mounting shell 4, the staff can use the cleaning mechanism to clean the heating wire 7. Cleaning is more convenient and labor-saving. After cleaning, the heating effect of the heating wire 7 can be effectively improved.

[0026] In a further preferred embodiment of the present invention, the moving mechanism includes: a screw 10 rotatably mounted on the mounting shell 4; a second motor 11 fixedly mounted on the mounting shell 4, the output shaft of the second motor 11 being fixedly connected to the top end of the screw 10; a support block 12 threadedly mounted on the screw 10, one side of the support block 12 being fixedly connected to one side of the heating wire 7.

[0027] In this embodiment, the moving mechanism is used to retract the heating wire 7. When in use, the second motor 11 is started to drive the screw 10 to rotate. The screw 10 will drive the support block 12 to move vertically, and the support block 12 will drive the heating wire 7 to move vertically. At this time, the limit block 6 fixed to the heating wire 7 will also slide vertically on the limit rod 5, and then the heating wire 7 can be stably stored in the mounting shell 4. Conversely, the heating wire 7 can be moved out of the mounting shell 4 so that the heating wire 7 enters the shell 1.

[0028] In a further preferred embodiment of the present invention, the cleaning mechanism includes: a sliding rod 13 fixedly mounted on the inner wall of the slide groove, two springs 14 being slidably sleeved on the sliding rod 13; a connecting block 15 slidably mounted on the sliding rod 13, the connecting block 15 being in contact with the two springs 14; a mounting plate 16 welded to the connecting block 15, bristles 17 being provided on the mounting plate 16, two grooves being provided on the mounting plate 16, and a vibration motor 18 being fixedly mounted on the inner walls of the two grooves.

[0029] In this embodiment, the cleaning mechanism is used to clean the heating wire 7. When in use, the vibration motor 18 is started, and the vibration motor 18 will drive the mounting plate 16 to shake, so that the bristles 17 on the mounting plate 16 can clean the impurities attached to the heating wire 7 by vibration, thereby improving the use effect of the heating wire 7. During the cleaning process, the connecting block 15 connected to the mounting plate 16 will continuously slide vertically on the slide rod 13 and repeatedly squeeze the spring 14.

[0030] In a further preferred embodiment of the present invention, a controller 19 is fixedly mounted on one side of the mounting shell 4 , and the plurality of springs 14 are all made of stainless steel.

[0031] In this embodiment, through the use of the controller 19, the power consumption of the first motor 3 can be automatically adjusted according to the use of the heating wire 7. When the heating wire 7 is in use, the power of the first motor 3 is relatively large. When the heating wire 7 is not needed to be stored in the mounting shell 4, the power consumption function of the first motor 3 will be reduced. The spring 14 made of stainless steel ensures long-term stable operation under harsh working conditions and is not easy to rust, deform or fail.

[0032] In a further preferred embodiment of the present invention, a noise reduction layer 20 is fixedly mounted on the outer wall of the shell 1 , and the noise reduction layer 20 is made of polyester fiber cotton material.

[0033] In this embodiment, the noise reduction layer 20 made of polyester fiber cotton material can reduce the sound inside the housing 1 with its excellent sound absorption and sound insulation properties, thereby reducing the noise pollution caused to the surrounding environment.

[0034] In a further preferred embodiment of the present invention, an air inlet net 21 and an air outlet net 22 are fixedly mounted on the inner wall of the housing 1 , and both the air inlet net 21 and the air outlet net 22 are made of metal.

[0035] In this embodiment, the metal air inlet mesh 21 and the air outlet mesh 22 can effectively prevent larger objects from entering the housing 1 and can prevent objects from entering the housing 1 and causing damage to the fan blades.

[0036] In a further preferred embodiment of the present invention, baffles are fixedly mounted on the bottom ends of the limiting rod 5 and the screw rod 10, and both baffles are circular.

[0037] In this embodiment, the use of two baffles can prevent the limiting block 6 from being separated from the limiting rod 5 and can prevent the supporting block 12 from being separated from the screw rod 10.

[0038] To sum up, compared with the relevant technology, this solution can effectively prevent large objects from entering the shell 1 through the air inlet net 21 and the air outlet net 22, and can prevent objects from entering the shell 1 and causing damage to the fan blades. The first motor 3 can drive the fan blades to rotate, so that the external gas enters the shell 1 from the air inlet net 21, and then these gases are heated by the heating wire 7 and discharged from the air outlet net 22. Since the gas has been heated, the incinerator can be heated in advance. When the weather is hot and the heating wire 7 is not needed, the heating wire 7 can be put into the mounting shell 4 to reduce wind resistance. Through the coordinated use of the first conductive copper sheet 8, the second conductive copper sheet 9 and the controller 19, the fan can automatically adjust the power consumption of the first motor 3 according to the usage of the heating wire 7, thereby realizing automatic adjustment of the air supply volume. The cleaning mechanism can realize the cleaning of the heating wire 7, which is more convenient and labor-saving. After cleaning, the heating effect of the heating wire 7 can be effectively improved.
