Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model discloses a wireless vacuum cleaner, including a vacuum host 1 and a vacuum head 2. The vacuum host 1 includes a main housing 11 and a vacuum motor 12 arranged inside the main housing 11. The bottom and top of the vacuum motor 12 are respectively provided with a head shockproof pad 121 and a tail shockproof pad 122. A dust cup 13 is provided at the bottom of the main housing 11. A filter element 14 located at the bottom of the vacuum motor 12 is provided inside the dust cup 13. The dust cup 13 is provided with a filter element 14 located at the bottom of the vacuum motor 12. The dust suction pipe 3 is connected with 12, and the dust suction motor 12 is the heart of the vacuum cleaner. The dust suction motor 12 is composed of two parts: a motor part and a fan part. Since the vacuum cleaner motor has a very high requirement on the rotation speed, the motor mainly adopts a series-excited motor, also known as a series-excited motor. The inner bottom of the dust cup 13 is also hinged with a valve plate 132 for blocking the top of the dust suction pipe 3. When the dust suction motor 12 is started, the valve plate 132 is sucked open by suction, and the valve plate 132 can block the sucked garbage once to reduce the impact force.

[0026] The end of the dust suction pipe 3 away from the dust cup 13 is connected to the dust suction head 2, and the dust suction head 2 includes a dust suction base 21 and a water tank 22 arranged on one side of the dust suction base 21. The top of the water tank 22 is provided with a water sealing cover 221 and a water tank switch 222. The top of the dust suction base 21 is hinged with a connecting sleeve 23 which is sleeved with the dust suction pipe 3. The interior of the dust suction base 21 is provided with a dust collecting port 24 which is connected with the dust suction pipe 3. Water can be added to the interior of the water tank 22 by pulling open the water sealing cover 221. A small hole is provided at the bottom of the water tank 22 for drainage. The water tank switch 222 controls drainage through negative pressure. When the water tank switch 222 is closed, the interior of the water tank 22 is isolated from the external air and water cannot be discharged. The water tank switch 222 is pressed to tilt it up, so that the water tank 22 is connected to the air for drainage. The bottom of the dust suction base 21 is provided with a dust suction slot connected with the dust collecting port 24.

[0027] Specifically, the inner top of the dust cup 13 is provided with a filter foam 131 which is sleeved with the filter element 14. The interior of the head shockproof pad 121 is hollow in design, which facilitates the vacuum motor 12 to extract the space inside the vacuum tube 3 through the filter element 14. The interior of the main housing 11 is provided with a motor fixing block 15 located on the top of the tail shockproof pad 122. The motor fixing block 15 is used to install the vacuum motor 12. The arrangement of the head shockproof pad 121 and the tail shockproof pad 122 ensures the stability of the vacuum motor 12 when it is started, reduces vibration transmission, makes it more comfortable for users to hold, and greatly reduces the starting noise.

[0028] Specifically, the main housing 11 is internally provided with a lithium battery 16 located on the top of the motor fixing block 15. The lithium battery 16 is used to power the main control board 17 and the dust suction motor 12. The dust suction motor 12 is powered by the lithium battery 16, and there is no need to connect a charging cable when in use. The wireless design makes it more convenient to use. The main housing 11 is internally provided with a main control board 17 and a key panel 171 and a Type-C charging board 172 respectively located on both sides of the main control board 17. A switch component 173 having one end extending to one side of the main housing 11 is provided on one side of the key panel 171, and a charging board fixing component 174 having one end extending to the other side of the main housing 11 is provided on one side of the Type-C charging board 172. The Type-C charging cable can be used to connect to the mains for charging through the Type-C charging board 172, and the key panel 171 can be triggered by pressing the switch component 173 to start the dust suction motor 12 for operation.

[0029] Specifically, the main housing 11 is provided with a decorative panel 18 on its exterior, and both sides of the main housing 11 are provided with exhaust holes 19 . The air filtered by the filter element 14 is sucked away by the dust collecting motor 12 and discharged through the exhaust holes 19 .

[0030] Specifically, a card slot 111 is provided around the bottom of the main housing 11, and the dust cup 13 is movably connected to the bottom of the main housing 11 through the card slot 111. The card slot 111 and the dust cup 13 are connected by a rotating card engagement. This design method makes it convenient for users to remove the dust cup 13 to clean the filter element 14 and the garbage inside the dust cup 13.

[0031] Specifically, the filter element 14 is conical, and a gripping hole 112 is provided inside the main housing 11. The setting of the gripping hole 112 makes it convenient for the user to hold the main housing 11. The conical setting of the filter element 14 greatly increases the filtering area of ​​the filter element 14, effectively improves the cleaning time of a single cleaning operation, reduces the clogging frequency and the cleaning frequency, and is more convenient to use.

[0032] Specifically, a wiper strip 25 is provided at the bottom of the vacuum base 21, a universal connector 26 is hinged at the top of the vacuum base 21, and the bottom of the connecting sleeve 23 is hinged to the top of the universal connector 26. The wiper strip 25 can scrape water off the ground. Figure 3 The hinge direction between the dust suction base 21 and the universal connector 26 and the hinge direction between the universal connector 26 and the connecting sleeve 23 are cross-staggered. This design greatly increases the flexibility of the dust suction base 21.

[0033] Specifically, a small wheel 27 and a large wheel 28 are hinged at both ends of the bottom of the dust suction base 21, and a decorative panel 211 is provided on the top of the dust suction base 21. The small wheel 27 and the large wheel 28 are used to support the dust suction base 21 to move, so that the dust suction base 21 moves more smoothly and flexibly.

[0034] Specifically, the number of the dust suction pipe 3 is not less than one, see Figure 1 and Figure 2 The number of dust suction pipes 3 is not less than one, and the multiple dust suction pipes 3 are connected by threads or screw-on buckles. The design of multiple dust suction pipes 3 facilitates the user to control the distance between the vacuum cleaner host 1 and the vacuum cleaner head 2. The dust suction pipe 3 is connected to the dust collecting port 24 through a hose 29. The hose 29 adopts a corrugated tube, which is more resistant to bending and can ensure the integrity of the cavity in the tube without being squeezed.

[0035] To sum up, the cordless vacuum cleaner can effectively reduce the vibration transmission between the vacuum motor 12 and the main housing 11 through the head shockproof pad 121 and the tail shockproof pad 122, making it more comfortable for users to hold and quieter to use. The conical design of the filter element 14 greatly increases the filtering area of ​​the filter element 14, effectively prolongs the cleaning time of a single cleaning operation, reduces the clogging frequency and the cleaning frequency, is more convenient to use, has a simple and compact structure, is in line with economic benefits, and has broad application prospects.
