Description

Technical Field

[0001] This invention relates to the technical field of household cleaning equipment, specifically to a handheld vacuum cleaner. Background Technology

[0002] Vacuum cleaners, as household cleaning appliances, have evolved from bulky to compact, and their use has become increasingly widespread. The working principle of a vacuum cleaner is that the high-speed rotation of the internal motor draws dust into the vacuum cleaner along with the air, where it is filtered by the dust filter. The filtered air is then released back into the environment, improving environmental conditions and enhancing comfort and air quality.

[0003] Some existing vacuum cleaners include the vacuum cleaner body and a floor brush. The floor brush is one of the important components of a vacuum cleaner; it has a suction port at the front that sweeps up dust for the suction port to draw in. To enhance the functionality of the floor brush, a wet mopping module has been added. This wet mopping module is a vibrating plate module that is detachably mounted on the floor brush. The floor brush has an eccentric drive component that drives the reciprocating movement of the vibrating plate module, thereby achieving vibration cleaning. The installation can be selected according to usage needs, allowing for simultaneous sweeping and mopping, which is very convenient for those who require this feature.

[0004] However, the eccentric drive component on the existing floor brush is exposed. Although this facilitates the installation of the wet mopping module, the long-term exposure of the eccentric drive component is prone to damage, which may lead to the wet mopping module being unable to be installed and used properly. Summary of the Invention

[0005] The purpose of this invention is to provide a handheld vacuum cleaner to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a handheld vacuum cleaner, including a floor brush assembly and a wet mopping module. The floor brush assembly has a suction port. When the main unit is activated, it generates negative pressure suction, which draws debris into a dust collection bin through the suction port. The floor brush assembly has a drive assembly, a connecting groove, and a sliding track. The connecting groove is slidably connected to the sliding track. The drive assembly includes a drive unit and a baffle. The baffle covers the drive unit and has a connecting through hole. The wet mopping module includes a movable plate and a cleaning cloth. The cleaning cloth is fixed to one side of the movable plate, and a transmission component and a connecting block are provided on the other side of the movable plate. The transmission component extends into the through hole and is connected to the drive assembly. The connecting block is embedded in the connecting groove. The drive assembly drives the movable plate to reciprocate.

[0007] Furthermore, the drive unit includes a motor, a transmission rod, an eccentric wheel, and a drive plate connected in sequence. The eccentric wheel rotates on the horizontal surface of the movable plate. The eccentric wheel is provided with an eccentric protrusion, which is connected to the drive plate. The drive plate reciprocates under the drive of the eccentric protrusion. The drive plate abuts against the transmission component and drives the movable plate to reciprocate.

[0008] Furthermore, the drive plate is provided with a transmission groove and a limiting groove. The transmission groove is opened along a first direction, and the limiting groove is opened along a second direction. The floor brush assembly is provided with a limiting protrusion, and the limiting groove is sleeved on the limiting protrusion. The first direction and the second direction are set perpendicularly, and the drive plate reciprocates along the second direction.

[0009] Furthermore, the floor brush assembly is provided with a mounting cavity, the drive unit is located in the mounting cavity, the baffles on both sides of the drive plate are provided with the connecting through holes, the transmission component is a connecting rod, and the connecting rod is provided corresponding to the connecting through holes.

[0010] Furthermore, the drive plate is provided with a guide slope, which abuts against the connecting rod.

[0011] Furthermore, the connecting rod is a cylindrical rod.

[0012] Furthermore, there are four connecting through holes, which are located near the corners of the baffle.

[0013] Furthermore, the connecting groove is magnetically connected to the connecting block.

[0014] Furthermore, the handheld vacuum cleaner also includes a water tank that supplies water to the wet mopping module.

[0015] Furthermore, the floor brush assembly is equipped with a water circuit switch, and the water tank is connected to the water circuit switch via a connecting pipe.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. By setting a baffle, the drive unit is shielded and protected, avoiding the risk of damage from exposure. Simultaneously, the baffle has through holes allowing transmission components on the movable plate to extend and connect, enabling the connection and installation of the movable plate and the drive assembly.

[0018] 2. The drive unit includes a motor, transmission rod, eccentric wheel and drive plate connected in sequence. The drive plate directly abuts against the transmission components to realize the movement of the movable plate. This makes the overall force on the movable plate balanced during the movement, avoids positional deviation during reciprocating movement, reduces the failure rate of the wet mopping module and improves the cleaning effect.

[0019] 3. The drive plate is equipped with a guide ramp, which abuts against the transmission rod. By setting the guide ramp, the movement of the drive plate in the second direction can be converted into the movement of the movable plate in the first direction. The transmission rod is a cylindrical rod, and the small contact area between the cylindrical rod and the guide ramp effectively reduces frictional resistance, facilitating the guide ramp to drive the movement of the transmission rod.

[0020] 4. The handheld vacuum cleaner also includes a water tank, which supplies water to the wet mopping module. By separating the wet mopping module and the water tank, the wet mopping module is made lighter, easier to install, and less likely to fall off during use, making it more convenient for users.

[0034] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] Reference Figure 1-7As an embodiment of the present invention, a handheld vacuum cleaner includes a floor brush assembly 1 and a wet mopping module 2. The floor brush assembly 1 is provided with a suction port. When the main unit is activated, it generates negative pressure suction and sucks the garbage into the dust collection bin through the suction port. The floor brush assembly 1 is provided with a drive assembly 11, a connecting groove 12 and a sliding rail. The connecting groove 12 is slidably connected to the sliding rail. The drive assembly 11 includes a drive part 111 and a baffle 112. The baffle 112 covers the drive part 111 and is provided with a connecting through hole 1121. The wet mopping module 2 includes a movable plate 21 and a cleaning cloth 22. The cleaning cloth 22 is fixed on one side of the movable plate 21. The other side of the movable plate 21 is provided with a transmission member 211 and a connecting block 212. The transmission member 211 extends into the through hole 1121 and is connected to the drive assembly 11. The connecting block 212 is embedded in the connecting groove 12. The drive assembly 11 drives the movable plate 21 to move back and forth.

[0036] By setting up a baffle 112, the drive unit 111 is shielded and protected, avoiding the risk of damage caused by exposure of the drive unit 111. At the same time, the baffle 112 is provided with a through hole 1121, which allows the transmission component 211 on the movable plate 21 to extend and connect, realizing the connection and installation between the movable plate 21 and the drive assembly 11.

[0037] Specifically, the floor brush assembly 1 is provided with a mounting cavity 13, and the drive unit 111 is located in the mounting cavity 13. The drive unit 111 includes a motor 1111, a transmission rod 1112, an eccentric wheel 1113 and a drive plate 1114 connected in sequence. The eccentric wheel 1113 rotates on the horizontal surface of the movable plate 21. The eccentric wheel 1113 is provided with an eccentric protrusion 1115. The eccentric protrusion 1115 is connected to the drive plate 1114. The drive plate 1114 reciprocates through the drive of the eccentric protrusion 1115. The drive plate 1114 abuts against the transmission component 211 and drives the movable plate 21 to reciprocate. The drive plate 1114 is provided with a transmission groove and a limiting groove 1117. The transmission groove is opened along a first direction, and the limiting groove 1117 is opened along a second direction. The first direction and the second direction are set perpendicularly. The floor brush assembly 1 is provided with a limiting protrusion 1118. The limiting groove 1117 is fitted onto the limiting protrusion 1118. The limiting protrusion 1118 limits the movable position of the limiting groove 1117, that is, the drive plate 1114 can only reciprocate along the second direction. The movement of the movable plate 21 is achieved by the drive plate 1114 directly abutting against the transmission component 211. This ensures that the movable plate 21 is subjected to balanced force during movement, avoids positional deviation during reciprocating movement, reduces the failure rate of the wet mopping module 2, and improves the cleaning effect.

[0038] Furthermore, the drive plate 1114 is provided with a guide ramp 1119, which abuts against the connecting rod. By providing the guide ramp 1119, the movement of the drive plate 1114 in the second direction can be converted into the movement of the movable plate 21 in the first direction.

[0039] Specifically, connection through-holes 1121 are provided at the positions of the baffles 112 on both sides of the driving plate 1114. The transmission member 211 is a connecting rod, and the connecting rod is arranged corresponding to the connection through-holes 1121. In this embodiment, there are four connection through-holes 1121, and the four connection through-holes 1121 are arranged near the corners of the baffle 112. Four guiding inclined surfaces 1119 are provided on the driving plate 1114, and are arranged near the four corners of the driving plate 1114. After the transmission member 211 passes through the connection through-holes 1121, it abuts against the guiding inclined surfaces 1119. At this time, the transmission members 211 are respectively located on both sides of the driving plate 1114. Therefore, the reciprocating movement of the driving plate 1114 can drive the reciprocating movement of the transmission member 211. In this embodiment, the transmission rod 1112 is a cylindrical rod, and the contact area between the cylindrical rod and the guiding inclined surface of is small, which can effectively reduce the frictional resistance and facilitate the guiding inclined surface 1119 to drive the movement of the transmission rod 1112.

[0040] Furthermore, the connecting groove 12 and the connecting block 212 are magnetically connected. The magnetic connection can facilitate the disassembly and assembly of the wet mopping module 2. In other embodiments, the magnetic adsorption connection method can also be replaced with a clamping and fixing form.

[0041] Furthermore, the hand-held vacuum cleaner further includes a water tank 3, and the water tank 3 supplies water to the wet mopping module 2. By separately arranging the wet mopping module 2 and the water tank 3, the wet mopping module 2 is made lighter in weight, convenient to install, and not likely to fall off during use, which is convenient for users. By separately arranging the wet mopping module 2 and the water tank 3, the wet mopping module 2 is made lighter in weight, convenient to install, and not likely to fall off during use, which is convenient for users.

[0042] In this embodiment, a water path switch is provided on the floor brush assembly 1, and the water tank 3 is connected to the water path switch through a connecting pipe.
