[0043] Further, after the indicator light flashes the several times, the indicator light stays on for a third period of time and then goes out. Triggering the magnetic control switch by the magnet within the third period of time can cause the indicator light to go out in advance.

[0044] This application also provides a pairing method for a vacuum cleaner remote control. The vacuum cleaner includes a vacuum cleaner body and a remote control that can control the vacuum cleaner body to turn on and off. The vacuum cleaner body is provided with a motor for providing suction and a dust collection container for accommodating garbage. Further, the remote control is provided with a magnet, a first wireless communication module, and a pairing switch. The vacuum cleaner body is provided with a magnetic control switch and a second wireless communication module for wireless communication with the first wireless communication module. The pairing method includes:

[0045] Step 1, the vacuum cleaner body is powered on and switched to the remote control mode.

[0046] Step 2, the remote control is brought close to the magnetic control switch so that the magnetic control switch is triggered under the magnetic field of the magnet of the remote control, and the second wireless communication module enters the pairing state.

[0047] Step 3, trigger the pairing switch so that the first wireless communication module and the second wireless communication module perform pairing.

[0048] Further, when the vacuum cleaner body is powered on and switched to the remote control mode, the second wireless communication module is powered on. When the vacuum cleaner body is not in the remote control mode, the second wireless communication module is not powered on.

[0049] Further, during Step 3, triggering the magnetic control switch by the magnet will cause the second wireless communication module to exit the pairing state.

[0050] Further, the second wireless communication module is provided with a first pin. The first pin is grounded via the magnetic control switch. The magnetic control switch is turned on under the magnetic field of the magnet, pulling the first pin from a high level to a low level. In Step 2, the second wireless communication module enters the pairing state based on the low-level signal of the first pin. In Step 3, the second wireless communication module can exit the pairing state based on the low-level signal of the first pin.

[0051] Further, the magnetic control switch is a reed switch. The remote control can be brought close to the magnetic control switch to turn it on, and the magnetic control switch will turn off when the remote control is moved away. Based on the magnetic control switch being turned on under the magnetic field of the magnet of the remote control, the second wireless communication module enters or exits the pairing state.

[0052] Further, the vacuum cleaner body further includes an indicator light. The indicator light is electrically connected to the second wireless communication module. In Step 2, the indicator light stays on to indicate that the second wireless communication module has entered the pairing state.

[0053] Further, a push button is used for the pairing switch. Step 3 is further to long-press the pairing switch for a first period of time. After step 3 is completed, the first wireless communication module and the second wireless communication module are successfully paired, and the first period of time is from 3 seconds to 8 seconds.

[0054] Further, the vacuum cleaner body further includes an indicator light, and the indicator light is electrically connected to the second wireless communication module. The pairing method further includes:

[0055] Step 4, after step 3, the indicator light flashes a first number of times to remind the user that the pairing is successful. The first number of times is from 2 to 5 times, and the indicator light stays on during step 3.

[0056] Further, the pairing method further includes step 5 after step 4: the indicator light stays on for a third period of time and then goes out.

[0057] Further, triggering the magnetic control switch by the magnet within the third period of time when the indicator light stays on will cause the indicator light to go out in advance. The third period of time is from 6 seconds to 12 seconds. When the magnet on the remote control triggers the magnetic control switch during steps 4 and 5, steps 4 and 5 end in advance and the indicator light goes out. The early end of steps 4 and 5 does not change the fact that the remote control has been successfully paired after passing through step 3.

Specific Embodiments

[0072] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0073] Refer Figures 1 to 13 As shown, the vacuum cleaner includes a vacuum cleaner body 10 and a remote control 11 that can remotely control the vacuum cleaner body 10 to turn on and off. The vacuum cleaner body 10 is provided with a motor 20 that provides suction, a dust collection container 30 that accommodates garbage, and a first switch. The remote control 11 is provided with a magnet 40 corresponding to the first switch. The first switch is a magnetic control switch that can be triggered under the action of the magnetic field of the magnet 40 of the remote control 11. The magnet 40 can be a permanent magnet, such as a magnetite, a magnet, etc. The remote control 11 controls the motor 20 to turn on and off to control the vacuum cleaner body 10 to turn on and off. Since the first switch is a magnetic control switch, by setting a corresponding magnet 40 on the remote control 11, the remote control 11 can trigger the first switch on the vacuum cleaner body 10 with its magnet 40, which is beneficial to expanding or enriching the functions of the remote control 11, and thus beneficial to enhancing the practicability of the remote control 11. The rated power of the motor 20 is between 100w and 3000w, preferably between 200w and 1800w, such as 960w, 1200w, 1320w, 1440w; the capacity of the dust collection container 30 is between 0.5 gallons (1 gallon = 3.785412 liters) and 30 gallons, preferably between 1 gallon and 20 gallons, such as 6 gallons, 9 gallons, 10 gallons, 12 gallons, 14 gallons, 16 gallons.

[0074] The magnetic control switch is located inside the vacuum cleaner body 10 and cannot be seen from outside the vacuum cleaner body 10. Since mechanical switches (such as push-button switches and rocker switches) that are directly operated by hand force often need to be external or exposed for easy operation by hand, they are vulnerable to external erosion and damage. In addition, it is often necessary to open an open switch accommodation hole in the housing 21 of the head 2 of the vacuum cleaner body 10 to accommodate the mechanical switch. However, the magnetic control switch triggered by a magnetic field inside the vacuum cleaner body 10 does not require manual touch operation to trigger, and there is no need to set an open switch accommodation hole in the housing 21 of the vacuum cleaner body 10 to place the magnetic control switch, which also reduces the safety protection burden such as waterproofing and anti-erosion. The magnetic control switch is preferably a normally open switch. The remote controller 11 can approach the magnetic control switch to turn on the magnetic control switch, and when the remote controller 11 is removed, the magnetic control switch is turned off. The magnetic control switch is further preferably a reed switch 22. The remote controller 11 can approach the reed switch 22 so that the reed switch 22 is turned on under the magnetic field of the magnet 40. The reed switch 22 is also called a tongue reed switch or a magnetic reed switch, etc. It is a common magnetic control normally open switch. The reed switch 22 has two magnetizable metal reed pieces with overlapping ends, which are sealed in a glass tube or a plastic tube. The distance between the two reed pieces is only about a few micrometers. The glass tube or plastic tube is filled with high-purity inert gas. When not operated (i.e., when the magnet 40 is not close), the two reed pieces do not contact and the reed switch 22 is turned off. After the magnet 40 approaches, its magnetic field magnetizes the reed pieces, causing the ends of the two reed pieces to generate different polarities and attract and close each other, so that the reed switch 22 is turned on. After the remote controller 11 is removed, the magnetism of the two reed pieces disappears and they return to the separated state under the action of the elasticity of the reed pieces themselves, so that the reed switch 22 is turned off. The remote controller 11 can approach the reed switch 22 so that when the distance between the reed switch 22 and the magnet 40 is less than the first distance, the reed switch 22 is triggered under the magnetic field of the magnet 40. The first distance is 1.5 cm to 3 cm, preferably 2 cm. The first distance is the maximum distance at which the magnet 40 can effectively trigger the reed switch 22.

[0075] The remote controller 11 is also provided with a first wireless communication module 41, a first circuit board 42, a pairing switch 43, and a remote control switch 44. The first wireless communication module 41 is arranged on the first circuit board 42. Further, the first wireless communication module 41 is adhesively welded to the first circuit board 42. The pairing switch 43 is electrically connected to the first wireless communication module 41, and the remote control switch 44 is electrically connected to the first wireless communication module 41. The vacuum cleaner body 10 is also provided with a second wireless communication module 23 for wireless communication with the first wireless communication module 41. The second wireless communication module 23 is located inside the vacuum cleaner body 10, and the magnetic control switch is electrically connected to the second wireless communication module 23. The pairing switch 43 preferably adopts a push-button switch, and the remote control switch 44 also preferably adopts a push-button switch. The first wireless communication module 41 is provided with a first antenna 410, and the second wireless communication module 23 is provided with a second antenna 230 for communication with the first antenna 410.

[0076] The remote controller 11 is further provided with a remote controller housing 45. The magnet 40 and the first wireless communication module 41 are located inside the remote controller housing 45, and the first wireless communication module 41 is located behind the magnet 40. The magnet 40 is arranged forward to facilitate the magnet 40 approaching the magnetic control switch. The first circuit board 42 is located inside the remote controller housing 45, and the first wireless communication module 41 is arranged on the first circuit board 42. The remote controller housing 45 is provided with a front wall 450, a rear wall 451, a bottom wall 452, and a top wall 453. The magnet 40 is located between the front wall 450 and the first circuit board 42, and the magnet 40 is arranged close to the front wall 450. The front wall 450, the magnet 40, the first circuit board 42, and the rear wall 451 are sequentially distributed in the front-rear direction. The remote controller housing 45 of this embodiment is assembled by upper and lower halves, locked together by screws. A sealing ring 46 is provided between the upper and lower halves to enhance the tightness between the upper and lower halves of the remote controller housing 45. An inner frame wall 454 is further provided inside the remote controller housing 45. The inner frame wall 454 extends upward from the bottom wall 452. The inner frame wall 454 is located between the front wall 450 and the first circuit board 42. The cross-section of the inner frame wall 454 is U-shaped. The inner frame wall 454 is connected to the front wall 450 to enclose a first accommodation space 455 for accommodating the magnet 40.

[0077] The remote controller 11 is further provided with a battery 49. The battery 49 abuts against and is electrically connected to the first circuit board 42. The battery 49 is located between the magnet 40 and the first wireless communication module 41. The battery 49 and the first wireless communication module 41 are located between the first circuit board 42 and the top wall 453. The remote controller 11 is further provided with a remote control light. The remote control light includes an LED light-emitting body 470 arranged on the first circuit board 42 and a light-transmitting body 471 that transmits light to the outside of the remote controller 11. Triggering the remote control switch 44 will cause the remote control light to light up once. The battery 49 is a button battery. The remote controller 11 is further provided with a metal frame 480. The metal frame 480 is welded to the first circuit board 42. The metal frame 480 and the first circuit board 42 enclose a second accommodation space 481 for accommodating the battery 49. The battery 49 is inserted into the second accommodation space 481 from the front end of the second accommodation space 481. A notch 420 is left at the front edge of the first circuit board 42 to facilitate removing the button battery. In a direction perpendicular to the first circuit board 42, at least part of the front part of the button battery overlaps with the notch 420. The notch 420 penetrates both opposite sides of the first circuit board 42 in the said direction (perpendicular to the first circuit board 42). Such a design of the notch 420 provides space for a person's finger to insert or pinch out the button battery 49 from the second accommodation space 481. The front edge of the battery 49 abuts against the inner frame wall 454.

[0078] The machine head 2 is installed together with the dust collection container 30. The motor 20 is part of the machine head 2, and the magnetic control switch is located inside the housing 21. The machine head 2 is also provided with a handle 29 and a second switch 24 exposed outside the housing 21 and used to switch the vacuum cleaner body 10 to the remote control mode. The housing 21 is provided with a through hole 210 penetrating the inside and outside of the housing 21 and at least partially accommodating the second switch 24, and a first outer wall 211 exposed outside the housing 21. The magnetic control switch is located inside the first outer wall 211 and is disposed close to the first outer wall 211. The first outer wall 211 separates the magnetic control switch from the outside of the vacuum cleaner body 10. The minimum distance between the magnetic control switch and the first outer wall 211 is less than 1 cm, preferably 0 cm (i.e., the magnetic control switch is in contact with the first outer wall 211), 0.1 cm, 0.2 cm, 0.3 cm, 0.4 cm. The second switch 24 is preferably a conventional rocker switch and has three gears: on, off, and remote control. In the off gear, the vacuum cleaner body 10 is turned off, the motor 20 does not work and cannot be remotely controlled; in the on gear, the vacuum cleaner body 10 is turned on, the motor 20 operates normally, but cannot be remotely controlled; only in the remote control gear can the vacuum cleaner body 10 be remotely controlled by the remote control 11. In this embodiment, when the vacuum cleaner body 10 is switched to the remote control mode, it means that the vacuum cleaner body 10 is switched to the remote control gear; the method of switching the vacuum cleaner body 10 to the remote control mode is not limited to this. For example, a remote control button can also be set on the vacuum cleaner body 10, and the remote control mode can be switched by triggering the remote control button; it can only be remotely controlled by the remote control 11 in the remote control mode. Of course, the premise is that the first wireless communication module 41 and the second wireless communication module 23 have been paired before, otherwise it cannot be remotely controlled; when the vacuum cleaner body 10 is connected to the power supply and switched to the remote control mode, the second wireless communication module is powered on; when the vacuum cleaner body 10 is not in the remote control gear, the second wireless communication module has no power, and of course it cannot be remotely controlled or paired. The vacuum cleaner body 10 can be powered by a battery pack or alternating current. In this embodiment, the vacuum cleaner body 10 is connected to the alternating current through the plug 27.

[0079] During remote control, when the remote control switch 44 is pressed, the vacuum cleaner body 10 is turned on and the motor 20 starts to work. When the remote control switch 44 is pressed again, the vacuum cleaner body 10 is turned off and the motor 20 stops. The machine head 2 is also provided with a second circuit board 25 and a main circuit board 28 located inside the housing 21. The second circuit board 25 is electrically connected to the main circuit board 28 through a circuit. The second wireless communication module 23 is disposed on the main circuit board 28, and the magnetic control switch is provided on the second circuit board 25. The second circuit board 25 faces the first outer wall 211, and the magnetic control switch is located between the second circuit board 25 and the first outer wall 211. The first outer wall 211 is provided with a remote control area 2110 on its outside. The magnet 40 is located at the front end of the remote control 11. When the front end of the remote control 11 abuts against the remote control area 2110, the magnetic control switch is turned on under the magnetic field of the magnet 40. The remote control area 2110 is a planar area, and the remote control area 2110 can be marked by labels or the like.

[0080] The remote controller 11 is preferably a bracelet-type remote controller 11, so that it can be worn on the human wrist for convenient portable use. The remote controller housing 45 and the components inside it (magnet 40, first wireless communication module 41, first circuit board 42, pairing switch 43, remote control switch 44, etc.) constitute the remote controller body. The wristband of the remote controller 11 is detachably assembled to the remote controller housing 45. The remote controller housing 45 is provided with positioning protrusions 50, a first through groove 51, and a second through groove 52 that are embedded in the wristband. The positioning protrusion 50 is located between the first through groove 51 and the second through groove 52. The wristband partially penetrates into the first through groove 51 and the second through groove 52. The first through groove 51 and the second through groove 52 are provided on opposite sides of the bottom wall 452 for limiting the wristband. The remote controller housing 45 is further provided with a first raised portion 53 and a second raised portion 54. The bottom wall 452 abuts against the wristband. Opposite ends of the first raised portion 53 and opposite ends of the second raised portion 54 are respectively connected to the bottom wall 452. The first raised portion 53 and the second raised portion 54 are located on opposite sides of the positioning protrusion 50. The first raised portion 53 and the bottom wall 452 enclose the first through groove 51, and the second raised portion 54 and the bottom wall 452 enclose the second through groove 52. The first through groove 51 and the second through groove 52 are located on opposite sides of the remote controller housing 45. The first through groove 51 and the second through groove 52 are parallel. Opposite ends of the first raised portion 53 and opposite ends of the second raised portion 54 are respectively integrally connected to the bottom wall 452. The first raised portion 53 and the second raised portion 54 respectively protrude from the positioning protrusion 50. With such a design, since the wrist has a curvature, the first raised portion 53 and the second raised portion 54 respectively protruding from the positioning protrusion 50 make the remote controller housing more compatible with the wrist. The first surface 456 of the bottom wall 452 facing away from the top wall 453 abuts against the wristband, and the positioning protrusion 50 protrudes from the first surface 456. The positioning protrusion 50 is integrally connected to the bottom wall 452, and the positioning protrusion 50 extends from the bottom wall 452 in a direction away from the top wall 453.

[0081] The wristband is provided with a central hole 600. The positioning protrusion 50 is matched with the central hole 600. The positioning protrusion 50 is embedded in the central hole 600. The wristband is made of a flexible material. Preferably, the wristband is made of rubber. The positioning protrusion 50 is cylindrical and matches the aperture of the central hole 600. The central hole 600 has a certain binding force on the positioning protrusion 50. The central hole 600 is a through hole. The free end of the positioning protrusion 50 does not extend beyond the central hole 600 but is within the central hole 600. With such a design, the free end of the positioning protrusion 50 is retracted within the central hole 600, avoiding a foreign body sensation caused by the positioning protrusion 50 when the wristband remote control 11 is worn on the wrist. The wristband includes a first band portion 61 and a second band portion 62. The first band portion 61 is provided with a buckle 610. The buckle 610 is located at the end portion of the first band portion 61. The second band portion 62 is provided with a plurality of fastening holes 620 for cooperating with the buckle 610 and an end ring 621 located at the end of the second band portion 62. These fastening holes 620 are arranged in a row in the length direction of the wristband. These fastening holes 620 are located between the end ring 621 and the remote control housing 45. The end portion of the first band portion 61 can pass through the end ring 621 and the buckle 610 can be selectively fastened to any one of these fastening holes 620. With such a design, the buckle 610 not only functions to fasten the first band portion 61 to the second band portion 62, but also the end of the first band portion 61 can be held on the second band portion 62 through the buckle 610, without the need for an additional loop to hold the end portion of the first band portion 61 on the second band portion 62, making the wristband design more concise.

[0082] The buckle 610 can be detached from the first band portion 61. The buckle 610 is provided with a seat body 611 and a pin portion 612. The pin portion 612 extends integrally from the seat body 611. The first band portion 61 is further provided with an assembly hole 613. The assembly hole 613 is located at the end portion of the first band portion 61. The buckle 610 is assembled in the assembly hole 613. The pin portion 612 is provided with a large head portion 614 and an outer flange 615. An inner flange 616 is provided within the assembly hole 613. The outer flange 615 is located between the large head portion 614 and the seat body 611. The large head portion 614 and the outer flange 615 respectively expand the inner flange 616 and pass through the inner flange 616. The large head portion 614 extends outside the assembly hole 613 for fastening with the fastening hole 620. The outer flange 615 is located within the assembly hole 613. The inner flange 616 is limited between the seat body 611 and the outer flange 615. The assembly hole 613 is further provided with a recess 617 for accommodating the seat body 611. The outer flange 615 and the inner flange 616 are respectively annular.

[0083] The buckle hole 620 is provided with a first hole section 622 and a second hole section 623. The aperture of the second hole section 623 is larger than that of the first hole section 622. When the buckle 610 is buckled to the buckle hole 620, the large head portion 614 passes through the first hole section 622 by expanding the first hole section 622 and is received in the second hole section 623 after passing through the first hole section 622. The end portion of the first belt portion 61 passes through the first through slot 51 when the buckle 610 is not installed, and the end portion of the first belt portion 61 cannot pass through the first through slot 51 when the buckle 610 is installed on the first belt portion 61; the end portion of the first belt portion 61 passes through the second through slot 52 and the first through slot 51 in sequence when the buckle 610 is not installed, and the end portion of the first belt portion 61 cannot pass through the second through slot 52 when the buckle 610 is installed on the first belt portion 61. The size of the buckle 610 is relatively large, resulting in the necessity to remove or not install the buckle 610 so that the end portion of the first belt portion 61 can freely pass through the second through slot 52 and the first through slot 51. Since the buckle 610 is detachable, it can be separately manufactured and formed, does not hinder the forming of the wristband body, and can be made of a stronger material. In the application, the buckle 610 can be a hard plastic part or a metal part. The wristband further includes a middle belt portion 60. The first belt portion 61, the middle belt portion 60, and the second belt portion 62 are integrally connected in sequence in the length direction of the wristband. The first through slot 51 is the boundary between the first belt portion 61 and the middle belt portion 60, and the second through slot 52 is the boundary between the second belt portion 62 and the middle belt portion 60. The middle belt portion 60 abuts against the remote control housing 45, and a middle hole 600 is provided in the middle belt portion 60.

[0084] The magnetic control switch is electrically connected to the second wireless communication module 23. The remote control 11 can approach the magnetic control switch to trigger the magnetic control switch under the magnetic field of the magnet 40. Based on the remote control 11 approaching the magnetic control switch to trigger the magnetic control switch, the second wireless communication module 23 enters the pairing state or exits the pairing state. The so-called pairing is the process of pairing or handshaking between the first wireless communication module 41 and the second wireless communication module 23. The first wireless communication module 41 and the second wireless communication module 23 must be successfully paired before they can be used. Without successful pairing, the second wireless communication module cannot identify the first wireless communication module 41, and thus there is no way to perform remote control; when the first wireless communication module 41 and the second wireless communication module 23 are successfully paired, they can be normally used for remote control without re-pairing in the future, unless the pairing information of the first wireless communication module 41 and the second wireless communication module 23 is cleared, in which case re-pairing is required before use; the first wireless communication module 41 and the second wireless communication module 23 can adopt existing wireless communication modules on the market.

[0085] Based on the magnetic control switch being turned on under the magnetic field of the magnet 40 of the remote control 11, the second wireless communication module 23 enters the pairing state or exits the pairing state. The second wireless communication module 23 entering the pairing state means that the remote control pairing switch 43 can be operated for pairing. Refer Figure 11, the second wireless communication module 23 is provided with a first pin 231. The first pin 231 is grounded via a magnetic control switch. The magnetic control switch is turned on under the action of the magnetic field of the magnet 40, and the first pin 231 is pulled down from a high level to a low level. The second wireless communication module 23 enters and exits the pairing state based on the low-level signal of the first pin 231; if the second wireless communication module 23 is in the pairing state, the second wireless communication module 23 receives the low-level signal of the first pin 231 and exits the pairing state. If the second wireless communication module 23 is not in the pairing state, the second wireless communication module 23 receives the low-level signal of the first pin 231 and enters the pairing state. The second wireless communication module 23 switches states based on the low-level signal of the first pin 231. Basically, every time the second wireless communication module 23 receives a low-level signal of the first pin 231, it will switch states once, thereby entering or exiting the pairing state. When the vacuum cleaner body is powered on and switched to the remote control mode, the second wireless communication module is powered on; after the second wireless communication module 23 is powered on, when the magnet 40 initially triggers the magnetic control switch, the second wireless communication module 23 enters the pairing state. The vacuum cleaner body 10 is also provided with an indicator light 26 (see Figure 11 ), the indicator light 26 is electrically connected to the second wireless communication module 23. After the second wireless communication module 23 is powered on, when the magnet 40 initially triggers the magnetic control switch, the indicator light 26 stays on continuously to indicate that the second wireless communication module 23 has entered the pairing state. The indicator light 26 is fixed to the housing 21 of the vacuum cleaner body 10. During the pairing process between the second wireless communication module 23 and the first wireless communication module 41, triggering the magnetic control switch by the magnet 40 will cause the second wireless communication module 23 to exit the pairing state. When the magnetic control switch is a reed switch 22, triggering the magnetic control switch means turning on the reed switch 22.

[0086] If the pairing between the second wireless communication module 23 and the first wireless communication module 41 is successful, the indicator light 26 flashes for the first number of times to remind the user that the pairing is successful. The first number of times is 3 to 5 times; in other embodiments, the indicator light 26 can also be provided on the remote control 11 and electrically connected to the first wireless communication module 41. After the indicator light 26 flashes for the first number of times, the indicator light 26 stays on continuously for a third time and then goes out. Triggering the magnetic control switch by the magnet 40 within this third time can cause the indicator light 26 to go out in advance; the third time is 8 seconds to 12 seconds, preferably 10 seconds. Therefore, if the user does not want to wait and wants the indicator light 26 to go out in advance, the user can trigger the magnetic control switch with the remote control 11 within this third time, which can cause the indicator light 26 to go out immediately.

[0087] In the present application, the effective communication distance between the first wireless communication module 41 and the second wireless communication module 23 is 20 meters, so remote control can be performed at a longer distance; in the present application, the first wireless communication module 41 and the second wireless communication module 23 are preferably in a one-to-one pairing relationship. If the first wireless communication module 41 is to be paired with other second wireless communication modules 23, it is necessary to first cancel the original pairing between the first wireless communication module 41 and the originally paired second wireless communication module 23. The one-to-one pairing relationship enables one remote control 11 to only remotely control one vacuum cleaner body 10 and one vacuum cleaner body 10 can only be controlled by one remote control 11, so that there is a completely one-to-one relationship between the remote control 11 and the vacuum cleaner body 10, and there will be no confusion in remote control, but the versatility is weakened; if you need to clear the pairing, long press the pairing switch 43 on the remote control 11 for a second time, and the second The time is 3 seconds to 8 seconds, preferably 5 seconds. If the pairing switch 43 on the remote control 11 is pressed and held for a second time, the indicator light 26 will flash several times to indicate that the pairing is cleared; based on different actual application scenarios, the first wireless communication module 41 and the second wireless communication module 23 can be configured into a one-to-many, many-to-one, or many-to-many relationship, so that it can be applied to a variety of application scenarios, such as one remote control 11 can remotely control multiple vacuum cleaner bodies 10 or one vacuum cleaner body 10 can be controlled by multiple remote controls 11, etc. The above configuration and pairing program can be realized by burning the software code into the first wireless communication module 41 and the second wireless communication module 23, which belongs to conventional technology and is therefore not repeated here. In this embodiment, the first wireless communication module 41 and the second wireless communication module 23 both use the wireless communication module model DL-BK24K6 available on the market.

[0088] The coding method of the vacuum cleaner remote controller 11 includes:

[0089] Step 1: The vacuum cleaner body 10 is connected to a power source and switched to a remote control mode;

[0090] Step 2, the remote control 11 is brought close to the magnetic switch so that the magnetic switch is triggered by the magnetic field of the magnet 40 of the remote control 11, and the second wireless communication module 23 enters the code binding state;

[0091] Step 3, trigger the pairing switch 43 to pair the first wireless communication module 41 with the second wireless communication module 23. During step 3, if the magnet 40 triggers the magnetic switch, the second wireless communication module 23 will exit the pairing state, thus failing to pair. Therefore, do not bring the remote control 11 close to the magnetic switch during step 3.

[0092] In Step 2, the indicator light 26 stays on constantly to indicate that the second wireless communication module 23 enters the pairing state. If Step 3 is not performed after Step 2, the indicator light 26 will stay on constantly until the vacuum cleaner body 10 is powered off. After powering on again, the entire pairing process can be restarted from Step 1. The pairing switch 43 is a push button. Step 3 further involves long-pressing the pairing switch 43 for a first period of time; after Step 3 is completed, the first wireless communication module 41 and the second wireless communication module 23 are successfully paired. The first period of time is from 3 seconds to 8 seconds; preferably 5 seconds. The pairing method further includes Step 4: after Step 3, the indicator light 26 flashes a first number of times to remind the user that the pairing is successful. The first number of times is from 2 to 5 times, preferably 3 times. During Step 3, the indicator light 26 stays on constantly. The pairing method also includes Step 5 after Step 4: the indicator light 26 stays on for a third period of time and then goes out; triggering the magnetic control switch by the magnet 40 within the third period of time when the indicator light 26 is on will cause the indicator light 26 to go out in advance. The third period of time is from 6 seconds to 12 seconds, preferably 8 seconds or 10 seconds. During Steps 4 and 5, triggering the magnetic control switch by the magnet 40 of the remote controller 11 will cause the processes of Steps 4 and 5 to end in advance and the indicator light 26 to go out. Since Step 4 usually only flashes the light a few times and the process is very fast, the operator usually does not trigger the magnetic control switch to end the pairing process in advance during Step 4; while Step 5 lasts for a longer time, if you want the indicator light 26 to go out immediately after knowing that the pairing is successful, you can trigger the magnetic control switch; Steps 4 and 5 are the end of the entire pairing process and mainly serve to prompt the user. The fact that Steps 4 and 5 end in advance does not change the fact that the pairing has been successful after Step 3.
