[0032] 1 to 12 , a handheld floor cleaning machine includes a main body portion 1 and a floor brush portion 2 .

[0033] The main unit 1 includes a water tank support 3 for mounting a clean water tank 8 and a dirt tank 7, a suction device 4 mounted on the top of the water tank support 3 and connected to the dirt tank 7, and a handle 5 plugged into the suction device 4. The previous structure of integrated assembly by the supporting shell is eliminated. The main unit 1 is assembled and connected in sequence by the water tank support 3, the suction device 4 and the handle 5, which effectively solves the problem of the bloated structure of the main unit 1, thereby achieving the effect of reducing the volume of the machine and further reducing the weight of the entire machine.

[0034] The top of the water tank support 3 is provided with an embedded portion 31 for installing the suction device 4, and the embedded portion 31 is provided with a connecting port 32 connected to the dirt tank 7 and a grounding terminal; the suction device 4 has an insertion channel 43 for inserting the handle 5, and the bottom of the suction device 4 is provided with an insertion seat 41 that is fitted with the embedded portion 31 at the top of the water tank support 3 and an electrical port that docks with the grounding terminal to electrically connect the suction device to the water tank component 3 and the electrical components of the floor brush part 2, and a suction port 42 connected to the internal suction motor is provided at the bottom of the insertion seat 41, and buckles are respectively arranged on both sides of the insertion seat 41, and the buckles arranged on both sides of the embedded portion 31 are respectively provided with buckle grooves 33, and the buckles are inserted into the buckle grooves 33 to realize the installation connection of the suction device 4 and the water tank support 3; the water tank support 3, the suction device 4 and the handle 5 are assembled and connected in sequence, eliminating the previous structure of integrated assembly by the support shell, effectively solving the problem of the bloated structure of the main unit 1, thereby achieving the effect of reducing the volume of the machine and then reducing the weight of the whole machine.

[0035] Moreover, one of the groups of buckles on the insertion seat 41 of the suction device 4 is a movable buckle, which is linked to the mounting structure of the suction device 4 by the handle 5. The group of buckles includes a buckle I 61 and an elastic member I 62. The buckle I 61 is arranged inside the insertion seat 41 and the elastic member I 62 is clamped between the buckle I 61 and the inner wall of the insertion seat 41. The buckle I 61 can be elastically extended and retracted through the insertion seat 41 by the elastic member I 62. The buckle I 61 is driven by the handle 5. The handle 5 is inserted into the insertion channel 43 to push the buckle I 61 out of the insertion seat 41 and snap into the buckle groove 33. Then the movable buckle is locked, and When the handle 5 is pulled out of the insertion channel 43, the buckle I61 is disengaged from the buckle groove 33 and retracted into the insertion seat 41 under the action of the elastic member I62, and the movable buckle is loosened and unlocked. The movable buckle is locked and loosened with the buckle groove 33 of the embedded part 31 by disassembling and assembling the handle 5, thereby realizing the locking and release of the suction device 4 and the water tank support 3 while realizing the insertion and removal of the handle 5. The embedded part 31 does not need to be provided with multiple unlocking structures, further simplifying the structure of the embedded part 31, making the structure of the water tank support 3 very light and simple, thereby realizing the simplification of the structure of the main body part 1.

[0036] When installing the suction device 4, the user first inserts the insertion seat 41 of the suction device 4 into the embedded portion 31, and locks the other buckle with the buckle groove 33 first, then inserts the handle 5 into the insertion channel 43 of the suction device 4 and pushes the buckle I 61 out of the insertion seat 41 and into the buckle groove 33 after the handle 5 is installed in place, so that the two movable buckles are locked and the suction device 4 is fixed on the water tank support 3. The opposite operation is performed when disassembling.

[0037] As a preferred solution, another set of buckles on the insertion seat 41 of the suction device 4 is also a movable buckle, including a buckle II 63 and an elastic member II 64. The buckle II 63 is installed on the side wall of the insertion seat 41 and is elastically pushed out by the elastic member II 64 to engage with the buckle groove 33. The embedded part 31 is provided with a press switch 34 located on the side of the buckle groove 33 and can push the buckle II 63 out of the buckle groove 33. Since the buckles at both ends of the insertion seat 41 are movable buckles, the installation of the suction device 4 and the embedded part 31 is more flexible and simple, and the suction device 4 can be disassembled and assembled in a straight line along the axial direction relative to the embedded part 31, so that the power port and the power terminal are directly plugged in, thereby avoiding the situation where the power port and the power terminal are misaligned and collided due to the installation inclination angle of the suction device 4 during installation, resulting in damage to the power terminal.

[0038] Furthermore, a mounting groove 46 for installing the buckle II 63 is provided on the outside of the insertion seat 41, and a hinge shaft is provided on the side of the buckle II 63 for rotatably installing in the mounting groove 46. The elastic member II 64 is clamped between the lower part of the buckle II 63 and the mounting groove 46, so that the buckle II 63 forms a seesaw structure and its lower part remains in an ejected state under the action of the elastic member II 64. The press switch 34 is arranged on the lower side of the buckle groove 33. Pressing the press switch 34 will push the lower part of the buckle II 63 to compress the elastic member II 64 and make the buckle II 63 disengage from the buckle groove 33.

[0039] Preferably, the mounting portion 31 is a mounting cavity with side walls. The snap grooves 33 are arranged on the side walls. These snap grooves 33 are two grooves corresponding to the two sets of active snap positions. Accurate positioning between these two points ensures secure circumferential and axial positioning of the suction device 4. Multiple vertical ribs 36 are evenly distributed along the circumference of the side walls of the mounting portion 31. These ribs enhance the tightness of the mounting portion 31 and the insertion seat 41, reducing excess clearance, and mitigate frictional forces when the mounting portion 31 and the insertion seat 41 come into contact.

[0040] Furthermore, an elastic positioning buckle 47 is provided on the side wall of the insertion seat 41 between the buckles on both sides, and a positioning slot 35 is provided in the side wall of the embedded part 31 for the elastic positioning buckle 47 to be inserted into, thereby enhancing the circumferential positioning effect and reducing the force load on the two sets of movable buckles.

[0041] As a preferred solution of the present invention, a push rod 44 that can move up and down is provided at the bottom of the insertion channel 43 to simplify the internal structure of the installation of the handle 5. There is no need to extend the handle 5 to the area where the buckle I 61 is located to drive the buckle I 61. After the handle 5 is inserted into the insertion channel 43 and installed in place, it presses the top of the push rod 44, causing the push rod 44 to move downward and contact the buckle I 61 from the bottom end, pushing the buckle I 61 out of the insertion seat 41 and snapping into the buckle groove 33. Furthermore, a pushing slope 441 facing the buckle I61 is provided at the bottom end of the push rod 44, and a pressure seat 611 is provided at the top of the buckle I61. A pressure slope 612 cooperating with the pushing slope 441 is provided on the pressure seat 611, so that the pushing action of the push rod 44 on the buckle I61 is more stable and smooth. The elastic member I62 is clamped between the pressure seat 611 and the inner wall of the insertion seat 41, and can be compressed and stored in time, and the buckle I61 is immediately rebounded to its original position after the bottom end of the push rod 44 leaves the buckle I61, and it is out of the buckle groove 33 in time.

[0042] Preferably, in order to ensure the stable sliding movement of the buckle I 61, a guide groove 45 for the sliding installation of the buckle I 61 is provided inside the insertion seat 41, and the end of the guide groove 45 passes through the side wall of the insertion seat 41 for the buckle I 61 to pass through.

[0043] The water tank support 3 includes a mounting base 37 pivotally connected to the floor brush part 2, a connecting base 39 with an embedded portion 31 formed on the top, and a connecting vertical rod 38 connected between the mounting base 37 and the connecting base 39. A clean water tank 8 and a dirt tank 7 are detachably installed between the mounting base 37 and the connecting base 39, and the dirt tank 7 and the clean water tank 8 are arranged on opposite sides of the connecting vertical rod 38. The supporting shell structure is eliminated and the connecting vertical rod 38 is used as the supporting skeleton of the entire floor scrubber. The internal space of the support rod is effectively reduced. In addition, the mold manufacturing cost of the support shell can be reduced, thereby achieving the purpose of reducing costs.
