[0071] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0072] Ginseng Figures 1 to 13 As shown, the vacuum cleaner includes a vacuum cleaner body 10, a remote controller 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 force, a dust collection container 30 that contains garbage, and a first switch, and the remote controller 11 is provided with a magnet 40 corresponding to the first switch, and the first switch is a magnetically controlled switch that can be triggered under the action of the magnetic field of the magnet 40 of the remote controller 11. The magnet 40 can be a permanent magnet, such as a magnet, a magnet, etc. The remote controller 11 controls the turning on and off of the motor 20 to control the turning on and off of the vacuum cleaner body 10. Since the first switch is a magnetically controlled switch, by providing a corresponding magnet 40 on the remote controller 11, the remote controller 11 can use its magnet 40 to trigger the first switch on the vacuum cleaner body 10, which is conducive to expanding or enriching the role of the remote controller 11, thereby enhancing the practicality of the remote controller 11. The rated power of the motor 20 is between 100w and 3000w, preferably between 200w and 1800w, for example 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, for example 6 gallons, 9 gallons, 10 gallons, 12 gallons, 14 gallons, 16 gallons.

[0073] The magnetic control switch is located inside the vacuum cleaner body 10, and the magnetic control switch 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 to facilitate hand force operation, they are easily eroded and damaged by the outside world. In addition, it is often necessary to open an open switch receiving hole in the shell 21 of the head 2 of the vacuum cleaner body 10 to accommodate the mechanical switch. The magnetic control switch is triggered by the magnetic field inside the vacuum cleaner body 10, so it does not need to be triggered by human touch operation. There is no need to set an open switch receiving hole in the shell 21 of the vacuum cleaner body 10 to place the magnetic control switch, which also reduces the safety protection burden of waterproofing and anti-corrosion. The magnetic control switch is preferably a normally open switch. The remote control 11 can be close to the magnetic control switch to turn on the magnetic control switch, and the magnetic control switch is turned off when the remote control 11 is removed. The magnetic control switch is further preferably a reed switch 22. The remote control 11 can be close to 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, also known as a tongue reed switch or a magnetic reed switch, is a common magnetically controlled normally open switch. The reed switch 22 has two magnetizable metal reeds with overlapping ends, which are sealed in a glass tube or a plastic tube. The distance between the two reeds is only about a few microns. The glass tube or the plastic tube is filled with a high-purity inert gas. Before operation (that is, when the magnet 40 is not close), the two reeds are not in contact, so the reed switch 22 is disconnected. When the magnet 40 approaches, its magnetic field magnetizes the reeds, causing the ends of the two reeds to have different polarities and attract each other and close, so that the reed switch 22 is connected. After the remote control 11 is removed, the magnetism of the two reeds disappears and the reeds return to a separated state under the action of their own elasticity, so that the reed switch 22 is disconnected. The remote control 11 can be close to the reed switch 22 so that the distance between the reed switch 22 and the magnet 40 is less than a first distance, and the reed switch 22 is triggered under the action of 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.

The vacuum cleaner body 10 is turned off by pressing the remote control switch 44 again, so that 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 line. The second wireless communication module 23 is arranged on the main circuit board 28. The magnetic control switch is arranged on the second circuit board 25. The second circuit board 25 faces the first outer side wall 211. The magnetic control switch is located between the second circuit board 25 and the first outer side wall 211. The first outer side wall 211 is provided with a remote control area 2110 located outside thereof. The magnet 40 is located at the front end of the remote control 11. When the front end of the remote control 11 is attached to 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 plane area. The remote control area 2110 can be marked by a label or the like.

[0079] 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 its internal components (magnet 40, first wireless communication module 41, first circuit board 42, pairing switch 43, remote control switch 44, etc.) constitute the remote controller body, and the wristband of the remote controller 11 is detachably assembled on the remote controller housing 45. The remote controller housing 45 is provided with a positioning protrusion 50, a first through groove 51, and a second through groove 52 embedded in the wristband. The positioning protrusion 50 is located between the first through groove 51 and the second through groove 52, and the wristband partially penetrates the first through groove 51 and the second through groove 52. The first through groove 51 and the second through groove 52 are arranged on opposite sides of the bottom wall 452 to limit the wristband. The remote control housing 45 is further provided with a first raised portion 53 and a second raised portion 54. The bottom wall 452 is in contact with the wristband. The opposite ends of the first raised portion 53 and the 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 form a first through groove 51, and the second raised portion 54 and the bottom wall 452 form a second through groove 52. The first through groove 51 and the second through groove 52 are located on opposite sides of the remote control housing 45. The first through groove 51 and the second through groove 52 are parallel. The opposite ends of the first raised portion 53 and the opposite ends of the second raised portion 54 are respectively connected to the bottom wall 452 in one piece. The first raised portion 53 and the second raised portion 54 protrude from the positioning protrusion 50, respectively. This design is because the wrist has an arc, and the first raised portion 53 and the second raised portion 54 protrude from the positioning protrusion 50, respectively, so that the remote control housing and the wrist are more compatible. The first surface 456 of the bottom wall 452 facing away from the top wall 453 is in contact with 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 to a direction away from the top wall 453.

[0080] The wristband is provided with a middle hole 600, the positioning protrusion 50 matches the middle hole 600, the positioning protrusion 50 is embedded in the middle hole 600, and the wristband is made of a flexible material. The wristband is preferably made of rubber material, the positioning protrusion 50 is cylindrical, matching the aperture of the middle hole 600, and the middle hole 600 has a certain binding force on the positioning protrusion 50. The middle hole 600 is a through hole, and the free end of the positioning protrusion 50 does not exceed the middle hole 600 but is inside the middle hole 600. With this design, the free end of the positioning protrusion 50 shrinks inside the middle hole 600, avoiding the positioning protrusion 50 giving a foreign body feeling when the wristband remote control 11 is worn on the wrist. The wristband includes a first strap portion 61 and a second strap portion 62. The first strap portion 61 is provided with a buckle 610, which is located at the end portion of the first strap portion 61. The second strap portion 62 is provided with a plurality of buckling holes 620 for cooperating with the buckle 610 and an end ring 621 located at the end of the second strap portion 62. The buckling holes 620 are arranged in a row in the length direction of the wristband. The buckling holes 620 are located between the end ring 621 and the remote control housing 45. The end portion of the first strap portion 61 can pass through the end ring 621 and the buckle 610 can be selectively buckled with any one of the buckling holes 620. With such a design, the buckle 610 not only buckles the first strap portion 61 to the second strap portion 62, but the end of the first strap portion 61 can also be kept on the second strap portion 62 through the buckle 610, without the need for an additional ring to keep the end portion of the first strap portion 61 on the second strap portion 62, and the wristband design is more concise.

[0081] The buckle 610 can be removed from the first belt 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 belt portion 61 is also provided with an assembly hole 613. The assembly hole 613 is located at the end of the first belt portion 61. The buckle 610 is assembled in the assembly hole 613. The pin portion 612 is provided with a large head 614 and an outer flange 615. An inner flange 616 is provided inside the assembly hole 613. The outer flange 615 is located between the large head 614 and the seat body 611. The large head 614 and the outer flange 615 respectively enlarge the inner flange 616 and pass through the inner flange 616. The large head 614 extends out of the assembly hole 613 to be engaged with the buckling hole 620. The outer flange 615 is located inside the assembly hole 613, and 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.

[0082] The buckle hole 620 is provided with a first hole section 622 and a second hole section 623. The second hole section 623 has a larger hole diameter than the first hole section 622. When the buckle 610 is buckled with the buckle hole 620, the large head 614 is passed through the first hole section 622 by expanding the first hole section 622 and then received in the second hole section 623. The end of the first belt portion 61 passes through the first through slot 51 when the buckle 610 is not installed, and cannot pass through the first through slot 51 when the buckle 610 is installed; the end 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 cannot pass through the second through slot 52 when the buckle 610 is installed. The buckle 610 is relatively large in size, so the buckle 610 must be removed or not installed so that the end 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 manufactured and formed separately, which does not hinder the molding of the wristband body and can be made of a stronger material. In the application, the buckle 610 can be a hard plastic or metal part. The wristband also includes a middle belt portion 60. The first belt portion 61, the middle belt portion 60, and the second belt portion 62 are 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 is close to the remote control housing 45, and the middle hole 600 is provided in the middle belt portion 60.

[0083] The magnetic control switch is electrically connected to the second wireless communication module 23. The remote control 11 can approach the magnetic control switch so that the magnetic control switch is triggered 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 paired successfully before they can be used. If the pairing is not successful, the second wireless communication module cannot recognize the first wireless communication module 41, and thus there is no way to remotely control; if the first wireless communication module 41 and the second wireless communication module 23 are paired successfully, there is no need to re-pair them in the future to use them normally, unless the pairing information of the first wireless communication module 41 and the second wireless communication module 23 is cleared, then they need to be re-paired before they can be used; the first wireless communication module 41 and the second wireless communication module 23 can use wireless communication modules already available on the market.

[0084] Based on the magnetic switch being turned on under the magnetic field of the magnet 40 of the remote controller 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 pairing switch 43 of the remote controller can be operated for pairing. Fig.11The second wireless communication module 23 is provided with a first pin 231, and the first pin 231 is grounded via a magnetically controlled switch. The magnetically controlled switch is turned on under the magnetic field of the magnet 40 and pulls the first pin 231 from a high level to a low level. The second wireless communication module 23 enters the code-binding state and exits the code-binding state based on the low-level signal of the first pin 231; if the second wireless communication module 23 is in the code-binding state, the second wireless communication module 23 receives the low-level signal of the first pin 231 and exits the code-binding state. If the second wireless communication module 23 is not in the code-binding state, the second wireless communication module 23 receives the low-level signal of the first pin 231 and enters the code-binding state. The second wireless communication module 23 switches the state based on the low-level signal of the first pin 231. Basically, the second wireless communication module 23 switches the state once each time it receives the low-level signal of the first pin 231, thereby entering the code-binding state or exiting the code-binding state. When the vacuum cleaner body is connected to a power source 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 triggers the magnetic switch for the first time, the second wireless communication module 23 enters the code pairing state. Fig.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 triggers the magnetic switch for the first time, the indicator light 26 is always on, indicating that the second wireless communication module 23 enters the code binding state. The indicator light 26 is fixed to the housing 21 of the vacuum cleaner body 10. When the second wireless communication module 23 is in the process of binding with the first wireless communication module 41, the magnet 40 triggers the magnetic switch to make the second wireless communication module 23 exit the code binding state. When the magnetic switch is a reed switch 22, triggering the magnetic switch means turning on the reed switch 22.

[0085] If the second wireless communication module 23 is successfully paired with the first wireless communication module 41, 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 for a third time and then goes out. Within the third time, the magnet 40 triggers the magnetic switch to make the indicator light 26 go out in advance. The third time is 8 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 remote control 11 can be used to trigger the magnetic switch within the third time, so that the indicator light 26 can go out immediately.

[0086] 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.

[0087] The coding method of the vacuum cleaner remote controller 11 includes:

[0088] Step 1, the vacuum cleaner body 10 is connected to a power source and switched to a remote control mode;

[0089] 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;

[0090] 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.

[0091] In step 2, the indicator light 26 is on for a long time to indicate that the second wireless communication module 23 enters the code pairing state. If step 3 is not performed after step 2, the indicator light 26 will continue to be on until the vacuum cleaner body 10 is turned off. After the power is turned on again, the entire code pairing process can be performed again from step 1. The code pairing switch 43 uses a press key, and step 3 is further to press the code pairing switch 43 for a long time and for a first time; after step 3 is completed, the first wireless communication module 41 and the second wireless communication module 23 are successfully paired, and the first time is 3 seconds to 8 seconds; preferably 5 seconds. The code pairing method also includes step 4: after step 3, the indicator light 26 flashes a first number of times to remind the user that the code pairing is successful, and the first number is 2 to 5 times, preferably 3 times. During step 3, the indicator light 26 is on for a long time. The code pairing method also includes step 5 after step 4: the indicator light 26 is on for a long time and then goes out; within the third time when the indicator light 26 is on, the magnet 40 triggers the magnetic control switch to make the indicator light 26 go out in advance. The third time is 6 seconds to 12 seconds, preferably 8 seconds or 10 seconds. During the process of step 4 and step 5, the magnet 40 of the remote control 11 triggers the magnetic switch, which will cause the process of step 4 and step 5 to end in advance and the indicator light 26 to go out. Because step 4 usually only flashes a few times and the process is very fast, the operator usually does not trigger the magnetic switch to end the code binding process in advance during step 4; while step 5 lasts for a long time, and if you want the indicator light 26 to go out immediately after knowing that the code binding is successful, you can trigger the magnetic switch; step 4 and step 5 are the end of the entire code binding process, mainly to remind the user, and the early end of step 4 and step 5 does not change the fact that the code binding has been successful after step 3.

Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
