Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Figure 2 shows the structure of a scrubber base 300. This scrubber base 300 includes: a first support 310 corresponding to a floor brush of the main body of the washing machine, and a second support 320 corresponding to a charging plug on the main body of the washing machine.

The first supporting portion 310 is provided with a roller brush groove 311, and a roller brush on the floor brush can rotate in the roller brush groove 310 to clean the roller brush. Heating elements can also be arranged in the roller brush groove 310 to dry the cleaned roller brush.

The second supporting part 320 is provided with a charging socket, and after the floor cleaning machine host is placed on the base, a charging plug on the host is plugged with the charging socket to form circuit communication, so that the host can be charged through the charging socket and the charging plug.

This floor cleaning machine base 300 still includes the waterproof construction that charges for prevent that conductive pin and water from contacting, thereby produce the electrolysis phenomenon and cause the charging failure in conductive pin department when avoiding charging.

With reference to fig. 2 to 10, the waterproof structure includes a tapered insulator 335 with a small top and a large bottom, and the tapered insulator 335 is disposed on a conductive pin support 339 of the base of the floor washing machine corresponding to the conductive pin 336.

In one embodiment, the tapered insulator 335 is integrally formed with the upper housing 337 of the pin support 339, such as by injection molding. Tapered insulator 335 may also be provided to conductive pin support 339 in other manners, such as by gluing. In general, the tapered insulator 335 should remain around the conductive pin 336 at all times.

Thus, when fluid enters the charging receptacle, the tapered insulator 335 directs the fluid around the conductive pin 336 to a location away from the conductive pin 336. During charging, the conductive pin 336 is not in contact with liquid, so that the electrolysis phenomenon can not be generated, and the charging failure caused by the electrolysis phenomenon can be avoided.

In one embodiment, the top surface of the supporting seat 339 further includes an upwardly arched portion 334, and the conductive pin 336 and the tapered insulator 335 are fixed to the arched portion 334. Thus, the liquid guided down by the conical insulator 335 is further guided by the arch 334 toward the periphery, further away from the conductive pin 336, so that the liquid can be better separated from the conductive pin 336.

In one embodiment, a through hole is formed in the edge of the arch 334, and the through hole extends downward to the bottom of the support 339, forming a drainage channel 341 connecting the top surface of the support 339 and the bottom of the support 339. Thus, the liquid guided by the conical insulator 335 and the arch 334 is discharged from the support seat through the drainage passage 341. Therefore, even if a large amount of liquid enters the charging socket, the liquid can be separated from the conductive pin 336, and the electrolysis phenomenon can be avoided. It will be appreciated that the flow channel 341 can be a separate element, such as a rigid or flexible tube, that joins the tube with the aperture at the edge of the arch 334 to form the flow channel.

In one embodiment, the supporting base 339 includes a lower base 338 and an upper base 337 fastened together by a buckle 342, and the buckle 342 includes a convex buckle 3421 at an outer side of the upper base 337 and a buckling position 3422 at an inner side of the lower base 338. A cavity 333 is formed between the lower base 338 and the upper base 337, a first elastic element 340 is sleeved on the conductive pin 336 in the cavity 333, the lower end of the first elastic element 340 is in butt fit with the lower base 338, and the upper end of the first elastic element is in butt fit with the conductive pin 336 to provide elastic force for enabling the conductive pin 336 to move upwards. In this way, since the conductive pin 336 can move up and down and has a tendency to move upward, it can make good contact with the contact electrode on the host computer during charging. In order to prevent the liquid from contacting the conductive pin 336 after penetrating into the cavity 333 and generating electrolysis during charging, a first water blocking wall 332 is further disposed on the top surface of the lower body 338 corresponding to the periphery of the conductive pin 336 for separating the liquid entering the cavity 333 from the conductive pin 336. Preferably, a drain hole is further formed at the bottom of the lower body 338 to drain the liquid in the cavity 333.

In one embodiment, a second water blocking wall 331 is further disposed on the bottom surface of the lower base 338 and around the conductive pin 336, and the second water blocking wall 331 can block liquid from contacting the conductive pin 336 from the lower surface of the lower base 338. Thereby achieving better anti-electrolysis effect.

The first and second water blocking walls 332 and 331 are preferably integrally formed with the lower base 338, and may also enhance the strength of the lower base 338.

In one embodiment, a door 344 is hinged to an insertion port of the charging socket 343, a second elastic member 345 is provided in the hinged portion, a torsion spring is used here, under the action of the second elastic member 345, the door 344 closes the insertion port of the charging socket 343, when the host is placed on the base, a charging plug on the host presses the door 344, the door 344 overcomes the elastic force of the second elastic member 345 and rotates inwards to open, the charging plug and the charging socket form a circuit connection, and an external power source can charge the host through a conductive pin of the charging socket and a contact electrode on the charging plug. When the host is removed from the base, the door 344 is rotated outward to close the insertion opening of the charging socket 343 by the second elastic element 345, so that the liquid cannot enter the charging socket 343 from the insertion opening.

Referring to fig. 11 and 12, in an embodiment, the charging waterproof structure of the floor washing machine further includes a third water blocking wall 101 on the main body 100 of the floor washing machine, the third water blocking wall 101 is disposed around the contact electrode of the charging plug 102, and after the liquid on the main body flows down, the liquid is blocked by the third water blocking wall 101 and does not flow to the contact electrode along the bottom surface of the charging plug 102, so that the contact electrode can be prevented from being electrolyzed during charging, and charging failure caused by the electrolysis at the contact electrode can be prevented during charging.

Referring to fig. 13, the floor washing machine of an embodiment includes a main body 100 and a base 300, wherein the base 300 is the base of the above-mentioned embodiment, the main body 100 includes a body assembly 110, a floor brush assembly 120 and a handle assembly 130, the body assembly 110 includes a clean water container 111, a sewage container 112 and a vacuum source, the floor brush assembly 120 is installed at a lower end of the body assembly 110, the floor brush assembly 120 includes a roller brush, a suction inlet communicated with the sewage container, and a spray head communicated with the clean water container, the handle assembly 130 is installed at an upper end of the body assembly 110, and the handle assembly 110 includes a control key.
