Description

Technical Field

[0001] The utility model relates to the technical field of air supply equipment, in particular to an air supply equipment. Background Art

[0002] With improved living standards, people are paying more attention to their health and demanding higher air quality, leading to a growing demand for fans with filtering capabilities. Fans with filters can pre-emptively remove dust, lint, and other impurities from the air, delivering clean, healthy air, and are highly sought after by consumers. However, with long-term use, if filters are not replaced promptly, dust, lint, and other impurities can accumulate on the filters, reducing airflow and affecting fan airflow. This increases the pressure on the input airflow, and prolonged operation of the fan in this state can lead to increased power consumption in the motor and motherboard, and continuous operation can damage the fan. Utility Model Content

[0003] Based on this, it is necessary to provide an air supply device to address the above-mentioned problems.

[0008] The detection component includes a detection blade, a resistance member and a detection member. The detection blade is rotatably installed in the air supply channel. The resistance member is used to apply resistance to the detection blade to hinder the rotation of the detection blade. The detection member is communicatively connected to the air supply body and is used to detect whether the detection blade to which resistance is applied is rotating.

[0009] When the air supply device in the above embodiment is used, the air supply body is powered on and works, and the air in the external environment is sucked into the air supply channel, generating a wind field in the air supply channel, causing the detection blade to rotate passively. The detection component monitors the rotation state of the detection blade, and the air in the air supply channel is filtered by the filter assembly and blown out to provide clean and healthy wind. At this time, the filter assembly is in the initial use state, and there is no impurities such as dust and lint in the air on its surface. The air penetration is high, and the air intake volume is large. The rotational torque applied to the detection blade is greater than the resistance of the resistance component to the detection blade, and the detection blade rotates passively. The detection component generates a normal signal and feeds it back to the air supply body, and the air supply body operates normally. As the air supply body continues to work, the amount of impurities such as dust and lint attached to the filter assembly continues to increase, the air penetration of the filter assembly gradually decreases, the wind field volume in the air supply channel gradually decreases, and the rotational torque applied to the detection blade also gradually decreases. When the rotational torque applied to the detection blade is less than the resistance of the resistance member to the detection blade, the detection blade stops rotating, the detection member generates a stop signal and feeds it back to the air supply body, the air supply body stops working, and reminds the user to replace the filter assembly in time to avoid malfunction of the air supply equipment due to excessive impurities attached to the filter assembly, thereby improving the reliability and safety of the air supply equipment.

[0031] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, an air supply device 10 is provided, comprising an air supply main body 100, a filter assembly 200 and a detection assembly 300. The air supply main body 100 is provided with an air supply channel 110. The filter assembly 200 is installed in the air supply channel 110. The detection assembly 300 comprises a detection blade 310, a resistance member 320 and a detection member 330. The detection blade 310 is rotatably installed in the air supply channel 110. The resistance member 320 is used to apply resistance to the detection blade 310 to hinder the rotation of the detection blade 310. The detection member 330 is communicatively connected to the air supply main body 100, and is used to detect whether the detection blade 310 to which resistance is applied is rotating.

[0033] When the air supply device 10 in the above embodiment is used, the air supply body 100 is powered on and the air in the external environment is sucked into the air supply channel 110. A wind field is generated in the air supply channel 110, causing the detection blade 310 to rotate passively. The detection member 330 monitors the rotation state of the detection blade 310. The air in the air supply channel 110 is filtered by the filter assembly 200 and blown out to provide clean and healthy air. At this time, the filter assembly 200 is in the initial use state, and its surface is free of impurities such as dust and lint in the air. The air penetration is high, and the air intake volume is large. The rotational torque applied to the detection blade 310 is greater than the resistance of the resistance member 320 to the detection blade 310. The detection blade 310 rotates passively, and the detection member 330 generates a normal signal and feeds it back to the air supply body 100, and the air supply body 100 operates normally. As the air supply body 100 continues to operate, the amount of impurities such as dust and lint attached to the filter assembly 200 continues to increase, the air penetration of the filter assembly 200 gradually decreases, the air volume in the air supply channel 110 gradually decreases, and the rotational torque applied to the detection blade 310 gradually decreases. When the rotational torque applied to the detection blade 310 is less than the resistance of the resistance member 320 to the detection blade 310, the detection blade 310 stops rotating, and the detection member 330 generates a stop signal and feeds it back to the air supply body 100, causing the air supply body 100 to stop operating and reminding the user to replace the filter assembly 200 in a timely manner. This prevents the air supply device 10 from malfunctioning due to excessive impurities attached to the filter assembly 200, thereby improving the reliability and safety of the air supply device 10.

[0034] It should be noted that the detection blade 310 will not rotate automatically after being powered on. The resistance applied by the resistance member 320 to the detection blade 310 can be flexibly adjusted according to actual use needs, thereby adjusting the maximum amount of impurities attached to the filter assembly 200.

[0035] The air supply body 100 can be configured as any structure for supplying air in the prior art. The filter assembly 200 can be configured as any filter structure in the prior art that can filter impurities such as dust and lint in the air.

[0036] Specifically, in this embodiment, the filter assembly 200 is detachably mounted within the air supply duct 110. The filter assembly 200 includes a filter holder 210 and a filter 220. The filter 220 is mounted on the filter holder 210, which is fixed within the air supply duct 110. This improves the ease of assembly of the filter assembly 200.

[0037] The number of detection assemblies 300 can be flexibly adjusted based on actual usage needs. The relative positions of the filter assembly 200 and the detection vane 310 within the air supply channel 110 can be flexibly adjusted based on actual usage needs. For example, along the axial direction of the air supply channel 110, the detection vane 310 can be installed on the side of the filter assembly 200 close to the air inlet, or on the side of the filter assembly 200 away from the air inlet, or can be installed on both sides of the filter assembly 200.

[0038] like Figure 2 、 Figure 3 and Figure 4 As shown, optionally, the air supply body 100 includes a rear net 120 and an air duct body 130 having an air supply channel 110. The air supply channel 110 has an air inlet, the rear net 120 is mounted at the air inlet, and the detection blade 310 is rotatably mounted on the rear net 120. In this way, the detection blade 310 can be pre-installed on the rear net 120 and then installed in the air supply channel 110 through the rear net 120, thereby improving the convenience of assembling the air supply device 10.

[0039] like Figure 2 As shown, in one embodiment, the resistance member 320 includes a first magnetic body 321 and a second magnetic body 322. The first magnetic body 321 is installed on the detection fan blade 310, and the second magnetic body 322 is installed on the rear mesh 120. The second magnetic body 322 is used to be attracted to the first magnetic body 321 to apply resistance to the detection fan blade 310.

[0040] Among them, the number of the first magnetic body 321 and the number of the second magnetic body 322 can be flexibly adjusted according to the actual needs of use. One of the first magnetic body 321 and the second magnetic body 322 is set as a first magnet, and the other is set as a second magnet or a magnetic metal part that can be attracted by the first magnet. Specifically in this embodiment, the first magnetic body 321 is set as the first magnet, and the second magnetic body 322 is set as the second magnet, and the magnetic properties of the first magnet and the second magnet are opposite. In this way, the second magnetic body 322 can apply stable and reliable resistance to the detection fan blade 310 through the first magnetic body 321, thereby improving the reliability of the air supply equipment 10.

[0041] It should be noted that the second magnetic body 322 may continuously apply resistance to the detection blade 310 through the first magnetic body 321 , or may intermittently apply resistance to the detection blade 310 through the first magnetic body 321 .

[0042] like Figure 2 and Figure 5As shown, optionally, the detection blade 310 includes a detection blade 311, and the first magnetic body 321 is disposed on the detection blade 311. In this way, the second magnetic body 322 intermittently applies resistance to the detection blade 310 through the first magnetic body 321, so that the detection blade 310 can rotate at a higher speed. The first magnetic body 321 can pass through the magnetic attraction area of ​​the second magnetic body 322 at a faster speed, ensuring smooth rotation of the detection blade 310.

[0043] like Figure 2 、 Figure 6 and Figure 7 As shown, optionally, the rear net 120 is provided with a mounting channel 121 communicating with the air inlet, and a mounting bracket 122 is provided in the mounting channel 121, and the detection blade 310 and the second magnetic body 322 are both mounted on the mounting bracket 122. In this way, the convenience of assembling the air supply device 10 is improved.

[0044] Specifically in this embodiment, the mounting bracket 122 is disposed at one end of the mounting channel 121 close to the air inlet. The detection blade 310 is mounted on a side of the mounting bracket 122 away from the air inlet and is located in the mounting channel 121.

[0045] like Figure 2 、 Figure 4 and Figure 5 As shown, specifically in this embodiment, the mounting bracket 122 is provided with a first mounting position 123 for mounting the detection blade 310. The detection blade 311 is provided with a second mounting position 312 for mounting the first magnetic body 321. The mounting bracket 122 is also provided with a third mounting position 124 corresponding to the second mounting position 312, and the third mounting position 124 is used to mount the second magnetic body 322.

[0046] In other embodiments, the resistance member 320 may also apply resistance to the detection blade 310 by frictionally engaging with the detection blade 310 or other methods.

[0047] like Figure 4 、 Figure 5 and Figure 7 As shown, in one embodiment, the detection member 330 includes a detection circuit 331 and a conductive contact 332. The detection circuit 331 is provided with a positive contact 333 and a negative contact 334. One of the detection circuit 331 and the conductive contact 332 is mounted on the detection blade 310, and the other is mounted on the rear mesh 120. The conductive contact 332 is configured to be in a state where the detection blade 310 rotates relative to the rear mesh 120 to a preset position (i.e., Figure 7 When the detection blade 310 is rotated away from the preset position, it is separated from at least one of the positive contact 333 and the negative contact 334.

[0048] Specifically, in this embodiment, when the detection blade 310 rotates to a predetermined position relative to the rear grille 120, the conductive contact 332 is connected to both the positive contact 333 and the negative contact 334, and the first magnetic body 321 and the second magnetic body 322 are correspondingly attracted. When the detection blade 310 rotates away from the predetermined position, the conductive contact 332 separates from at least one of the positive contact 333 and the negative contact 334, and the first magnetic body 321 and the second magnetic body 322 separate.

[0049] In other embodiments, the detection member 330 may also be configured as a camera, a rotation speed sensor, or other devices capable of detecting whether the fan blade 310 is rotating.

[0050] like Figure 6 and Figure 7 As shown, optionally, the detection blade 310 includes a blade body 314 having a mounting cavity 313. The detection circuit 331 is mounted in the mounting cavity 313. The positive contact 333 and the negative contact 334 both extend from a side of the blade body 314 near the conductive contact 332. In this way, the detection blade 310 can protect the detection circuit 331 and improve the reliability of the air supply device 10.

[0051] Specifically in this embodiment, a first mounting hole and a second mounting hole corresponding to the second magnetic body 322 are provided on one side of the fan blade body 314 close to the second magnetic body 322. The first mounting hole and the second mounting hole are both connected to the mounting cavity 313. The positive contact 333 extends out of the fan blade body 314 from the first mounting hole, and the negative contact 334 extends out of the fan blade body 314 from the second mounting hole.

[0052] like Figure 2 As shown, in one embodiment, the air supply body 100 further includes an air supply blade 140 rotatably installed in the air supply channel 110 , and the air supply blade 140 is coaxially arranged with the detection blade 310 .

[0053] like Figure 2 and Figure 3 As shown, specifically in this embodiment, the air supply body 100 also includes a motor 150 and a fan knob 160. The inner side wall of the air supply channel 110 is provided with a first bracket for mounting the motor 150, and a mounting groove for mounting the filter assembly 200. The output shaft of the motor 150 is suspended along the axial direction of the air supply channel 110. The air supply fan blades 140 are sleeved on the output shaft and are connected to the output shaft in a transmission manner. The fan knob 160 is mounted on the output shaft to fix the air supply fan blades 140 on the output shaft. When the motor 150 is energized to rotate the output shaft at high speed, the air supply fan blades 140 will rotate synchronously with the rotation direction of the output shaft, thereby achieving an air supply effect.

[0054] like Figure 2 and Figure 3 As shown, specifically in this embodiment, the air supply body 100 also includes a front net 170 and a mesh cover 180. The air supply channel 110 also has an air outlet arranged opposite to the inlet and outlet, and the front net 170 is installed at the air outlet. The mesh cover 180 is installed on the side of the installation channel 121 away from the air inlet. When the motor 150 is powered on, the motor 150 drives the air supply blades 140 to rotate, and the air in the external environment is sucked into the air supply channel 110 through the rear net 120, the mesh cover 180 and the filter screen 220, so that a wind field is generated in the air supply channel 110. In addition, the front net 170, the rear net 120 and the mesh cover 180 can all prevent the user's fingers from reaching into the air supply channel 110, thereby improving the safety of the air supply device 10.
