Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and particularly to a detection structure, air duct assembly, fan, and detection method. Background Technology

[0002] Currently, fans have evolved over the years and added many additional functions, such as heated fans that keep the fan warm in winter and cool in summer. However, customers need to be assured of the safety of such additional heating functions in order to better attract customers. Fans that are frequently used will also accumulate a lot of dust over time. Therefore, it is necessary to disassemble the fan's front grille to make it easier for users to clean its internal components.

[0003] However, when users manually remove or install the fan's front grille, they may forget to disconnect the fan's power supply. If the fan is leaking electricity at this time, it could cause an electric shock to the user.

[0004] In other words, in the existing technology, there is a risk of electric shock when users disassemble the fan. Summary of the Invention

[0005] This invention provides a detection structure, air duct assembly, fan, and detection method to address the risk of electric shock when users disassemble the fan.

[0006] This invention provides a detection structure for disassembling and assembling a fan, comprising:

[0007] A detection component, which is installed in the fan's air duct; and

[0008] The first moving component is mounted on the air duct and is configured in correspondence with the detection component;

[0009] When the front net of the air duct is installed on the air duct, one end of the first moving component is in contact with the front net, and the other end of the first moving component is against the detection component. The detection component is pressed and emits a first signal. When the front net is removed from the air duct, the first moving component moves a preset distance toward the front net so that the detection component is not pressed. At this time, the detection component stops emitting the first signal.

[0010] In one embodiment, a second movable component is also included. The second movable component is disposed on the air duct and is correspondingly disposed to the detection component. When the rear screen of the air duct is installed on the air duct, one end of the second movable component presses against the detection component, and the other end contacts the rear screen. At this time, the detection component emits a first signal. When the rear screen is removed from the air duct, the second movable component moves a preset distance toward the rear screen so that the detection component is not pressed. At this time, the detection component stops emitting the first signal.

[0011] In one embodiment, a first guide rail extends along a first direction on the air duct, and the first moving component includes:

[0012] A movable telescopic rod is slidably connected to the first guide rail; one end of the movable telescopic rod contacts the front net, and the other end is connected to the detection component; and

[0013] An elastic compression element is sleeved on the other end of the movable telescopic rod and located between the movable telescopic rod and the first guide rail;

[0014] When the current net is installed on the air duct, the detection component sends a first signal, the elastic compression component is in a compressed state, and an elastic restoring force is generated; when the current net is removed from the air duct, the elastic restoring force can push the first moving component to slide a preset distance along the first guide rail towards the front net, at which point the detection component stops sending the first signal.

[0015] In one embodiment, the detection component includes a first micro switch connected to the other end of a movable telescopic rod. When the current net is installed on the air duct, the first micro switch button is pressed and deformed, and the first micro switch sends a first signal. When the current net is removed from the air duct, the first movable component drives the first micro switch to move forward a preset distance, the first micro switch button returns to its initial position, and the first micro switch stops sending the first signal.

[0016] In one embodiment, the detection component further includes a mounting base in which a first micro switch is disposed. The first micro switch is connected to the other end of the movable telescopic rod via the mounting base. When the front net is removed from the air duct, the movable telescopic rod moves the front net a preset distance, the first micro switch returns to its initial position, and the first micro switch stops emitting the first signal.

[0017] In one embodiment, when both the front and rear nets are installed on the air duct, one end of the second moving component presses the first micro switch to deform it, and the first micro switch sends a first signal. The other end of the second moving component comes into contact with the rear net. When the rear net is removed from the air duct, the second moving component slides a preset distance toward the rear net, the first micro switch returns to its initial position, and the first micro switch stops sending the first signal.

[0018] In one embodiment, a second guide rail extends along a first direction on the air duct, and a second moving component is slidably connected to the second guide rail. When the rear net is removed from the air duct, the second moving component slides a preset distance along the second guide rail toward the rear net.

[0019] In one embodiment, a second movable component is also included. The second movable component is disposed on the air duct and is correspondingly disposed to the detection component. When the rear screen of the air duct is installed on the air duct, one end of the second movable component presses against the detection component, and the other end contacts the rear screen. At this time, the detection component emits a second signal. When the rear screen is removed from the air duct, the second movable component moves a preset distance toward the rear screen so that the detection component is not pressed. At this time, the detection component stops emitting the second signal.

[0020] In one embodiment, a first guide rail extends along a first direction on the air duct, and the first moving component includes:

[0021] The movable telescopic rod is slidably connected to the first guide rail; one end of the movable telescopic rod contacts the front net, while the other end presses against the detection component; and

[0022] An elastic compression element is sleeved on the other end of the movable telescopic rod and located between the movable telescopic rod and the first guide rail;

[0023] When the current net is installed on the air duct, the detection component sends a first signal, the elastic compression component is in a compressed state, and an elastic restoring force is generated; when the current net is removed from the air duct, the elastic restoring force can push the first moving component to slide a preset distance along the first guide rail towards the front net, at which point the detection component stops sending the first signal.

[0024] In one embodiment, the detection component includes a first micro switch fixed to the air duct; wherein, when the current net is installed on the air duct, the first micro switch button is pressed and deformed by the other end of the movable telescopic rod, and the first micro switch emits a first signal; when the current net is removed from the air duct, the movable telescopic rod moves the current net a preset distance, the first micro switch button returns to its initial position, and the first micro switch stops emitting the first signal.

[0025] In one embodiment, the detection component further includes a second micro switch fixed on the air duct. When the front net is installed on the air duct, the second micro switch button is pressed and deformed by the second moving component, and the second micro switch sends a second signal. When the rear net is removed from the air duct, the second moving component moves a preset distance toward the rear net, the second micro switch button returns to its initial position, and the second micro switch stops sending the second signal.

[0026] In one embodiment, the detection assembly further includes a mounting base fixed to the air duct, and a first micro switch and a second micro switch fixed inside the mounting base.

[0027] In one embodiment, a second guide rail extends along a first direction on the air duct, and a second moving component is slidably connected to the second guide rail. When the rear net is removed from the air duct, the second moving component moves a preset distance along the second guide rail toward the rear net.

[0028] In one embodiment, a control device is also included, which is electrically connected to the power supply of the detection component and the fan. When the detection component stops emitting the first signal, the control device cuts off the power supply to the fan.

[0029] The present invention also provides an air duct assembly, comprising:

[0030] Air duct; and

[0031] The detection structure described above;

[0032] The detection structure is installed on the air duct.

[0033] The present invention also provides a fan, comprising:

[0034] The aforementioned air duct components; and

[0035] The front grille, which is detachably mounted on one end of the air duct; and

[0036] The rear grille is detachably mounted on the other end of the air duct.

[0037] The present invention also provides a detection method for detecting the disassembly of the front grille of a fan, comprising:

[0038] Determine if the front grille is installed in the air duct;

[0039] With the front grille installed on the air duct, the detection component continuously emits the first signal;

[0040] When the front grille is removed from the air duct, the detection component stops sending the first signal.

[0041] Compared with existing technologies, the advantages of this invention are that by having the other end of the first moving component contact the detection component and apply pressure, the detection component deforms under pressure, triggering it to emit a first signal. This prompts the user that the front grille is installed on the air duct. By moving the first moving component a predetermined distance toward the front grille, the detection component is no longer under pressure, and at this point, the detection component stops emitting the first signal. This prompts the user to remove the front grille from the air duct. In other words, the user can determine the current installation status of the front grille by judging whether the detection component emits the first signal. This ensures that when the user determines that the front grille needs to be removed, the fan power can be disconnected in time, thus avoiding the risk of electric shock caused by the user operating without disconnecting the power. This ensures that the user can safely install and remove the front grille. Attached Figure Description

[0057] The invention will now be further described with reference to the accompanying drawings.

[0058] Example 1

[0059] like Figure 1 As shown, the present invention provides a detection structure for the disassembly and assembly of a fan, comprising a detection component 10 and a first moving component 20. The detection component 10 is disposed on the air duct 101 of the fan; the first moving component 20 is disposed on the air duct 101 and is correspondingly disposed to the detection component 10.

[0060] When the front net 102 is installed on the air duct 101, one end of the first moving component 20 contacts the front net 102, and the other end contacts the detection component 10. At this time, the detection component 10 is pressed and sends out a first signal. When the front net 102 is removed from the air duct 101, the first moving component 20 moves a preset distance toward the front net 102 so that the detection component 10 is not pressed. At this time, the detection component 10 stops sending out the first signal to prompt the front net 102 to be removed from the air duct 101.

[0061] In the above configuration, the other end of the first moving component 20 contacts the detection component 10, applying pressure to the detection component 10, causing it to deform and triggering the issuance of a first signal. This prompts the user that the front screen 102 is installed on the air duct 101. The first moving component 20 moves a preset distance towards the front screen 102, removing pressure from the detection component 10, at which point the detection component 10 stops issuing the first signal. This prompts the user to remove the front screen 102 from the air duct 101. In other words, the user can determine the current installation status of the front screen 102 by checking whether the detection component 10 issues a first signal. This ensures that the user can promptly disconnect the fan power when determining whether to remove the front screen 102, thus avoiding the risk of electric shock due to operation without disconnecting the power. This ensures that the user can safely install and remove the front screen 102.

[0062] Specifically, such as Figure 1 As shown, in one embodiment, a second moving component 30 is also included. The second moving component 30 is disposed on the air duct 101 and is correspondingly disposed with the detection component 10. When the rear net 103 is installed on the air duct 101, one end of the second moving component 30 presses against the detection component 10, and the other end abuts against the rear net 103. At this time, the detection component 10 sends out a first signal. When the rear net 103 is removed from the air duct 101, the second moving component 30 moves a preset distance toward the rear net 103 so that the detection component 10 is not pressed. At this time, the detection component 10 stops sending out the first signal to prompt the rear net 103 to be removed from the air duct 101.

[0063] In the above configuration, one end of the second moving component 30 presses against the detection component 10, causing the detection component 10 to deform under pressure and triggering it to emit a first signal. This indicates that both the front screen 102 and the rear screen 103 are installed on the air duct 101. The second moving component 30 moves a preset distance towards the rear screen 103, removing pressure from the detection component 10, at which point it stops emitting the first signal. This indicates that the rear screen 103 should be removed from the air duct 101. In other words, the current installation status of the rear screen 103 can be determined by whether the detection component 10 emits the first signal. This ensures that when the user determines whether to remove the rear screen 103, they can promptly disconnect the fan power supply, thus avoiding the risk of electric shock due to operation without disconnecting the power. Furthermore, it ensures that the user can safely install and remove the front screen 102.

[0064] As can be seen from the above, when either the front net 102 or the rear net 103, or both the front and rear nets, are removed from the air duct 101, the detection component 10 will stop sending the first signal. This ensures that the user can disconnect the fan power supply in a timely manner, thereby avoiding the risk of electric shock caused by the user operating without disconnecting the power. Furthermore, it ensures that the user can safely install and remove the front and rear nets.

[0065] Specifically, such as Figure 1 and Figure 6 As shown, in one embodiment, a first guide rail 1011 extends along a first direction on the air duct 101, and the first moving component 20 includes a movable telescopic rod 21 and an elastic compression member 22. The movable telescopic rod 21 is slidably connected to the first guide rail 1011, with one end of the rod abutting against the front net 102 and the other end connected to the detection component 10. The elastic compression member 22 is sleeved on the other end of the movable telescopic rod 21 and located between the rod 21 and the first guide rail 1011. When the front net 102 is installed on the air duct 101, the detection component 10 sends a first signal, the elastic compression member 22 is compressed, and an elastic restoring force is generated. When the front net 102 is removed from the air duct 101, the elastic restoring force can push the first moving component 20 to slide a preset distance along the first guide rail 1011 towards the front net 102, at which point the detection component 10 stops sending the first signal.

[0066] Specifically, such as Figure 1 As shown, in one embodiment, the elastic compression member 22 is a spring.

[0067] Specifically, such as Figure 1 and Figure 3As shown, in one embodiment, the detection component 10 includes a first micro switch 12 connected to the other end of the movable telescopic rod 21. When the current net 102 is installed on the air duct 101, the first micro switch button 121 of the first micro switch 12 is pressed and deformed, and the first micro switch 12 sends a first signal. When the current net 102 is removed from the air duct 101, the first movable component 20 drives the first micro switch 12 to move forward a preset distance towards the current net 102, the first micro switch button 121 returns to its initial position, and the first micro switch 12 stops sending the first signal. This realizes the detection function of the detection component 10.

[0068] Specifically, such as Figure 1 and Figure 4 As shown, in one embodiment, the detection component 10 further includes a mounting base 11, within which a first micro switch 12 is disposed. The first micro switch 12 is connected to the other end of the movable telescopic rod 21 via the mounting base 11. When the front net 102 is removed from the air duct 101, the first moving component 20 drives the mounting base 11 and the first micro switch 12 to move the front net 102 a preset distance, the first micro switch 121 returns to its initial position, and the first micro switch 12 stops emitting the first signal.

[0069] It should be noted that in this embodiment, the first signal is the signal emitted by the first micro switch.

[0070] Specifically, such as Figure 2 As shown, in one embodiment, a locking groove 211 is provided on the other end of the movable telescopic rod 21, and the locking groove 211 is locked and fixed to the mounting base 11.

[0071] Specifically, such as Figure 1 As shown, in one embodiment, when both the front net 102 and the rear net 103 are installed on the air duct 101, one end of the second moving component 30 presses the first micro switch 121 to deform it, and the first micro switch 12 sends a first signal. The other end of the second moving component 30 comes into contact with the rear net 103. When the rear net 103 is removed from the air duct 101, the second moving component 30 slides a preset distance toward the rear net 103, the first micro switch 121 returns to its initial position, and the first micro switch 12 stops sending the first signal.

[0072] In the above configuration, when either the front grille 102 or the rear grille 103, or when both the front and rear grilles are removed from the air duct 101, the detection component 10 stops sending the first signal. This ensures that the user can disconnect the fan power supply in a timely manner, thereby avoiding the risk of electric shock caused by the user operating without disconnecting the power. Furthermore, it ensures that the user can safely install and remove the front and rear grilles.

[0073] Specifically, in one embodiment, the first signal is configured to include two different types of signals, one of which indicates that the front net 102 is installed in the air duct 101, and the other of which indicates that the rear net 103 is installed in the air duct 101.

[0074] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, a second guide rail 1012 extends along a first direction on the air duct 101, and a second moving component 30 is slidably connected to the second guide rail 1012. When the rear net 103 is removed from the air duct 101, the second moving component 30 slides a preset distance along the second guide rail 1012 toward the rear net 103.

[0075] In the above configuration, a second guide rail 1012 is provided to guide the second moving component 30 to slide. This ensures that the second moving component 30 slides a preset distance toward the rear net 103, and the first micro switch 121 returns to its initial position, thereby ensuring that the first micro switch 12 stops sending the first signal.

[0076] Specifically, such as Figure 3 and Figure 4 As shown, in one embodiment, a positioning post 111 is provided on the mounting base, and a positioning hole 122 is provided on the first micro switch, with the positioning post 111 cooperating with the positioning hole 122.

[0077] Specifically, such as Figure 2 As shown, in one embodiment, a limiting shoulder 212 is provided on the movable telescopic rod 21 for compressing the spring.

[0078] Specifically, such as Figure 6 As shown, in one embodiment, a first slide rail 1013 is provided on the first guide rail 1011, and a second slide rail 1014 is provided on the second guide rail 1012.

[0079] Specifically, in one embodiment, a control device is also included, which is electrically connected to the power supply of the detection component 10 and the fan. When the detection component 10 stops emitting the first signal, the control device cuts off the power supply to the fan. This allows the detection structure to automatically cut off the power supply based on the current installation status of the front and rear nets, thereby avoiding the risk of electric shock caused by the user operating without disconnecting the power. This ensures that the user can safely install and remove the front and rear nets.

[0080] Specifically, in one embodiment, when both of the above-mentioned different types of signals are emitted, the control device can be set to automatically turn on the power.

[0081] Example 2

[0082] like Figure 7As shown, the present invention provides a detection structure for the disassembly and assembly of a fan, comprising a detection component 10 and a first moving component 20. The detection component 10 is disposed on the air duct 101 of the fan; the first moving component 20 is disposed on the air duct 101 and is correspondingly disposed to the detection component 10.

[0083] When the front net 102 is installed on the air duct 101, one end of the first moving component 20 contacts the front net 102, and the other end contacts the detection component 10. At this time, the detection component 10 is pressed and sends out a first signal. When the front net 102 is removed from the air duct 101, the first moving component 20 moves a preset distance toward the front net 102 so that the detection component 10 is not pressed. At this time, the detection component 10 stops sending out the first signal to prompt the front net 102 to be removed from the air duct 101.

[0084] In the above configuration, the other end of the first moving component 20 contacts the detection component 10, causing the detection component 10 to deform under pressure and triggering it to emit a first signal. This indicates that the front screen 102 is installed on the air duct 101. The first moving component 20 moves a preset distance towards the front screen 102, reducing the pressure on the detection component 10, at which point the detection component 10 stops emitting the first signal. This indicates that the front screen 102 should be removed from the air duct 101. In other words, the current installation status of the front screen 102 can be determined by whether the detection component 10 emits a first signal. This ensures that when the user needs to remove the front screen 102, they can promptly disconnect the fan power supply, thus avoiding the risk of electric shock due to operation without disconnecting the power. This ensures that the user can safely install and remove the front screen 102.

[0085] Specifically, such as Figure 7 As shown, in one embodiment, a second moving component 30 is also included. The second moving component 30 is disposed on the air duct 101 and is disposed corresponding to the detection component 10. When the rear net 103 of the air duct 101 is installed on the air duct 101, one end of the second moving component 30 presses against the detection component 10, and the other end abuts against the rear net 103. At this time, the detection component 10 emits a second signal. When the rear net 103 is removed from the air duct 101, the second moving component 30 moves a preset distance toward the rear net 103 so that the detection component 10 is not pressed. At this time, the detection component 10 stops emitting the second signal.

[0086] Specifically, such as Figure 7As shown, in one embodiment, a first guide rail 1011 extends along a first direction on the air duct 101. The first moving component 20 includes a telescopic rod 21 and an elastic compression member 22. The telescopic rod 21 is slidably connected to the first guide rail 1011, with one end of the telescopic rod 21 contacting the front net 102 and the other end pressing against the detection component 10. The elastic compression member 22 is sleeved on the other end of the telescopic rod 21 and located between the telescopic rod 21 and the first guide rail 1011. When the front net 102 is installed on the air duct 101, the detection component 10 sends a first signal, the elastic compression member 22 is compressed, and an elastic restoring force is generated. When the front net 102 is removed from the air duct 101, the elastic restoring force can push the first moving component 20 to slide a preset distance along the first guide rail 1011 towards the front net 102, at which point the detection component 10 stops sending the first signal. This realizes the front net detection function of the detection structure.

[0087] Specifically, such as Figure 7 As shown, in one embodiment, the elastic compression member 22 is a spring.

[0088] Specifically, such as Figure 7 As shown, in one embodiment, the detection component 10 includes a first micro switch 12, which is fixed to the air duct 101. When the current net 102 is installed on the air duct 101, the first micro switch button 121 of the first micro switch 12 is pressed and deformed by the other end of the movable telescopic rod 21, and the first micro switch 12 emits a first signal. When the current net 102 is removed from the air duct 101, the movable telescopic rod 21 moves the current net 102 a preset distance, the first micro switch button 121 returns to its initial position, and the first micro switch 12 stops emitting the first signal.

[0089] Specifically, such as Figure 7 As shown, in one embodiment, the detection component 10 further includes a second micro switch 13, which is fixed on the air duct 101. When the front net 102 is installed on the air duct 101, the second micro switch 13's second micro button 131 is pressed and deformed by the second moving component 30, and the second micro switch 13 sends a second signal. When the rear net 103 is removed from the air duct 101, the second moving component 30 moves a preset distance toward the rear net 103, the second micro button 131 returns to its initial position, and the second micro switch 13 stops sending the second signal.

[0090] It should be noted that in this embodiment, the second signal is the signal emitted by the second micro switch 13.

[0091] Specifically, such as Figure 7 As shown, in one embodiment, the detection component 10 further includes a mounting base 11, which is fixed on the air duct 101, and the first micro switch 12 and the second micro switch 13 are fixed inside the mounting base 11.

[0092] Specifically, such as Figure 7 As shown, in one embodiment, a second guide rail 1012 extends along a first direction on the air duct 101, and a second moving component 30 is slidably connected to the second guide rail 1012. When the rear net 103 is detached from the air duct 101, the second moving component 30 moves a preset distance along the second guide rail 1012 toward the rear net 103.

[0093] In the above configuration, a second guide rail 1012 is provided to guide the second moving component 30 to slide. This ensures that the second moving component 30 slides a preset distance toward the rear net 103, and the second micro switch 131 returns to its initial position, thereby ensuring that the second micro switch 13 stops emitting the second signal.

[0094] Specifically, in one embodiment, a control device is also included. The control device is electrically connected to the power supply of the detection component 10 and the fan. When the detection component 10 stops emitting the second signal or the first signal, or both the second and first signals, the control device cuts off the power supply to the fan. This allows the detection structure to automatically cut off or connect the power supply based on the current installation status of the front and rear nets; that is, the power is only connected when both the second and first signals are emitted simultaneously. This avoids the risk of electric shock caused by the user operating without disconnecting the power, thereby ensuring that the user can safely install and remove the front and rear nets.

[0095] Example 3

[0096] like Figure 8 As shown, the present invention also provides an air duct assembly, which includes an air duct 101 and the detection structure described in Embodiment 1 above. The detection structure is disposed on the air duct 101.

[0097] Specifically, such as Figure 1 As shown, the detection structure is used for the disassembly and assembly of the fan, and includes a detection component 10 and a first moving component 20. The detection component 10 is disposed on the air duct 101 of the fan; the first moving component 20 is disposed on the air duct 101 and is disposed corresponding to the detection component 10.

[0098] When the front net 102 is installed on the air duct 101, one end of the first moving component 20 contacts the front net 102, and the other end contacts the detection component 10. At this time, the detection component 10 is deformed by pressure and sends out a first signal. When the front net 102 is removed from the air duct 101, the first moving component 20 moves a preset distance toward the front net 102 so that the detection component 10 is not compressed. At this time, the detection component 10 stops sending out the first signal to prompt the front net 102 to be removed from the air duct 101.

[0099] In the above configuration, the other end of the first moving component 20 contacts the detection component 10, applying pressure to the detection component 10, causing it to deform and triggering the issuance of a first signal. This prompts the user that the front screen 102 is installed on the air duct 101. The first moving component 20 moves a preset distance towards the front screen 102, removing pressure from the detection component 10, at which point the detection component 10 stops issuing the first signal. This prompts the user to remove the front screen 102 from the air duct 101. In other words, the user can determine the current installation status of the front screen 102 by checking whether the detection component 10 issues a first signal. This ensures that the user can promptly disconnect the fan power when determining whether to remove the front screen 102, thus avoiding the risk of electric shock due to operation without disconnecting the power. This ensures that the user can safely install and remove the front screen 102.

[0100] Specifically, such as Figure 1 As shown, in one embodiment, a second moving component 30 is also included. The second moving component 30 is disposed on the air duct 101 and is correspondingly disposed with the detection component 10. When the rear net 103 is installed on the air duct 101, one end of the second moving component 30 presses against the detection component 10, and the other end abuts against the rear net 103. At this time, the detection component 10 sends out a first signal. When the rear net 103 is removed from the air duct 101, the second moving component 30 moves a preset distance toward the rear net 103 so that the detection component 10 is not pressed. At this time, the detection component 10 stops sending out the first signal to prompt the rear net 103 to be removed from the air duct 101.

[0101] In the above configuration, one end of the second moving component 30 presses against the detection component 10, causing the detection component 10 to deform under pressure and triggering it to emit a first signal. This indicates that both the front screen 102 and the rear screen 103 are installed on the air duct 101. The second moving component 30 moves a preset distance towards the rear screen 103, removing pressure from the detection component 10, at which point it stops emitting the first signal. This indicates that the rear screen 103 should be removed from the air duct 101. In other words, the current installation status of the rear screen 103 can be determined by whether the detection component 10 emits the first signal. This ensures that when the user determines whether to remove the rear screen 103, they can promptly disconnect the fan power supply, thus avoiding the risk of electric shock due to operation without disconnecting the power. Furthermore, it ensures that the user can safely install and remove the front screen 102.

[0102] As can be seen from the above, when either the front net 102 or the rear net 103, or both the front and rear nets, are removed from the air duct 101, the detection component 10 will stop sending the first signal. This ensures that the user can disconnect the fan power supply in a timely manner, thereby avoiding the risk of electric shock caused by the user operating without disconnecting the power. Furthermore, it ensures that the user can safely install and remove the front and rear nets.

[0103] Specifically, such as Figure 1 and Figure 6 As shown, in one embodiment, a first guide rail 1011 extends along a first direction on the air duct 101, and the first moving component 20 includes a movable telescopic rod 21 and an elastic compression member 22. The movable telescopic rod 21 is slidably connected to the first guide rail 1011, with one end of the rod abutting against the front net 102 and the other end connected to the detection component 10. The elastic compression member 22 is sleeved on the other end of the movable telescopic rod 21 and located between the rod 21 and the first guide rail 1011. When the front net 102 is installed on the air duct 101, the detection component 10 sends a first signal, the elastic compression member 22 is compressed, and an elastic restoring force is generated. When the front net 102 is removed from the air duct 101, the elastic restoring force can push the first moving component 20 to slide a preset distance along the first guide rail 1011 towards the front net 102, at which point the detection component 10 stops sending the first signal.

[0104] Specifically, such as Figure 1 and Figure 3 As shown, in one embodiment, the detection component 10 includes a first micro switch 12 connected to the other end of the movable telescopic rod 21. When the current net 102 is installed on the air duct 101, the first micro switch button 121 of the first micro switch 12 is pressed and deformed, and the first micro switch 12 sends a first signal. When the current net 102 is removed from the air duct 101, the first movable component 20 drives the first micro switch 12 to move forward a preset distance towards the current net 102, the first micro switch button 121 returns to its initial position, and the first micro switch 12 stops sending the first signal. This realizes the detection function of the detection component 10.

[0105] Specifically, such as Figure 1 As shown, in one embodiment, the elastic compression member 22 is a spring.

[0106] Specifically, such as Figure 1 and Figure 4 As shown, in one embodiment, the detection component 10 further includes a mounting base 11, within which a first micro switch 12 is disposed. The first micro switch 12 is connected to the other end of the movable telescopic rod 21 via the mounting base 11. When the front net 102 is removed from the air duct 101, the first moving component 20 drives the mounting base 11 and the first micro switch 12 to move the front net 102 a preset distance, the first micro switch 121 returns to its initial position, and the first micro switch 12 stops emitting the first signal.

[0107] Specifically, such as Figure 2 As shown, in one embodiment, a locking groove 211 is provided on the other end of the movable telescopic rod 21, and the locking groove 211 is locked and fixed to the mounting base 11.

[0108] Specifically, such as Figure 1As shown, in one embodiment, when both the front net 102 and the rear net 103 are installed on the air duct 101, one end of the second moving component 30 presses the first micro switch 121 to deform it, and the first micro switch 12 sends a first signal. The other end of the second moving component 30 comes into contact with the rear net 103. When the rear net 103 is removed from the air duct 101, the second moving component 30 slides a preset distance toward the rear net 103, the first micro switch 121 returns to its initial position, and the first micro switch 12 stops sending the first signal.

[0109] In the above configuration, when either the front grille 102 or the rear grille 103, or when both the front and rear grilles are removed from the air duct 101, the detection component 10 stops sending the first signal. This ensures that the user can disconnect the fan power supply in a timely manner, thereby avoiding the risk of electric shock caused by the user operating without disconnecting the power. Furthermore, it ensures that the user can safely install and remove the front and rear grilles.

[0110] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, a second guide rail 1012 extends along a first direction on the air duct 101, and a second moving component 30 is slidably connected to the second guide rail 1012. When the rear net 103 is removed from the air duct 101, the second moving component 30 slides a preset distance along the second guide rail 1012 toward the rear net 103.

[0111] In the above configuration, a second guide rail 1012 is provided to guide the second moving component 30 to slide. This ensures that the second moving component 30 slides a preset distance toward the rear net 103, and the first micro switch 121 returns to its initial position, thereby ensuring that the first micro switch 12 stops sending the first signal.

[0112] Specifically, in one embodiment, a control device is also included, which is electrically connected to the power supply of the detection component 10 and the fan. When the detection component 10 stops emitting the first signal, the control device cuts off the power supply to the fan. This allows the detection structure to automatically cut off the power supply based on the current installation status of the front and rear nets, thereby avoiding the risk of electric shock caused by the user operating without disconnecting the power. This ensures that the user can safely install and remove the front and rear nets.

[0113] Specifically, such as Figure 3 and Figure 4 As shown, in one embodiment, a positioning post 111 is provided on the mounting base, and a positioning hole 122 is provided on the first micro switch, with the positioning post 111 cooperating with the positioning hole 122.

[0114] Specifically, such as Figure 2 As shown, in one embodiment, a limiting shoulder 212 is provided on the movable telescopic rod 21 for compressing the spring.

[0115] Specifically, such as Figure 6 As shown, in one embodiment, a first slide rail 1013 is provided on the first guide rail 1011, and a second slide rail 1014 is provided on the second guide rail 1012.

[0116] Example 4

[0117] like Figures 9 to 12 As shown, the present invention also provides a fan, which includes the above-described air duct assembly, front grille 102 and rear grille 103. The front grille 102 is detachably disposed on one end of the air duct 101; the rear grille 103 is detachably disposed on the other end of the air duct 101.

[0118] like Figure 10 As shown, the fan also includes a heat-generating element 104, which is disposed on the air duct assembly. The air duct assembly enables the fan to blow hot air.

[0119] Specifically, such as Figure 1 , Figures 9 to 12 As shown, the detection structure is used for the disassembly and assembly of the fan, and includes a detection component 10 and a first moving component 20. The detection component 10 is disposed on the air duct 101 of the fan; the first moving component 20 is disposed on the air duct 101 and is disposed corresponding to the detection component 10.

[0120] When the front net 102 is installed on the air duct 101, one end of the first moving component 20 contacts the front net 102, and the other end contacts the detection component 10. At this time, the detection component 10 is pressed and sends out a first signal. When the front net 102 is removed from the air duct 101, the first moving component 20 moves a preset distance toward the front net 102 so that the detection component 10 is not pressed. At this time, the detection component 10 stops sending out the first signal to prompt the front net 102 to be removed from the air duct 101.

[0121] In the above configuration, the other end of the first moving component 20 contacts the detection component 10, applying pressure to the detection component 10, causing it to deform and triggering the issuance of a first signal. This prompts the user that the front screen 102 is installed on the air duct 101. The first moving component 20 moves a preset distance towards the front screen 102, removing pressure from the detection component 10, at which point the detection component 10 stops issuing the first signal. This prompts the user to remove the front screen 102 from the air duct 101. In other words, the user can determine the current installation status of the front screen 102 by checking whether the detection component 10 issues a first signal. This ensures that the user can promptly disconnect the fan power when determining whether to remove the front screen 102, thus avoiding the risk of electric shock due to operation without disconnecting the power. This ensures that the user can safely install and remove the front screen 102.

[0122] Specifically, such as Figure 1 , Figures 9 to 12As shown, in one embodiment, a second moving component 30 is also included. The second moving component 30 is disposed on the air duct 101 and is correspondingly disposed with the detection component 10. When the rear net 103 is installed on the air duct 101, one end of the second moving component 30 presses against the detection component 10, and the other end abuts against the rear net 103. At this time, the detection component 10 sends out a first signal. When the rear net 103 is removed from the air duct 101, the second moving component 30 moves a preset distance toward the rear net 103 so that the detection component 10 is not pressed. At this time, the detection component 10 stops sending out the first signal to prompt the rear net 103 to be removed from the air duct 101.

[0123] In the above configuration, one end of the second moving component 30 presses against the detection component 10, causing the detection component 10 to deform under pressure and triggering it to emit a first signal. This indicates that both the front screen 102 and the rear screen 103 are installed on the air duct 101. The second moving component 30 moves a preset distance towards the rear screen 103, removing pressure from the detection component 10, at which point it stops emitting the first signal. This indicates that the rear screen 103 should be removed from the air duct 101. In other words, the current installation status of the rear screen 103 can be determined by whether the detection component 10 emits the first signal. This ensures that when the user determines whether to remove the rear screen 103, they can promptly disconnect the fan power supply, thus avoiding the risk of electric shock due to operation without disconnecting the power. Furthermore, it ensures that the user can safely install and remove the front screen 102.

[0124] As can be seen from the above, when either the front net 102 or the rear net 103, or both the front and rear nets, are removed from the air duct 101, the detection component 10 will stop sending the first signal.
