It can remove more than 99.97% of particles with diameter of more than 0.3 micron (1/200 of hair diameter), and is the most effective filtering medium for smoke, dust and bacteria.

The term "surface cleaning system" includes various types of floor sweeping robots, such as automatic floor sweepers, intelligent floor mopping machines, intelligent floor cleaning machines, intelligent floor sweeping and cleaning machines, and the like, which are capable of performing a floor sweeping and cleaning operation. While the commercial name may vary, the function of cleaning/sanitizing surfaces is essentially fulfilled and is within the scope of the present invention. It will be appreciated by those skilled in the art that the scope of the present invention is defined by the appended claims.

The term "air duct" refers to the path of air flow through a surface cleaning apparatus, consisting of an inlet, an outlet, and a space between the inlet and the outlet.

As shown in fig. 1 and 2, in the present invention, the base 30 includes an upper tray 35, a lower tray 36, and a base fan 32.

In some embodiments of the invention, the upper tray 35 and the lower tray 36 are snap fit to form a cavity of the base 30. The base fan 32 is located at one end of the cavity, and the air outlet 33 is located at the other end of the cavity. The heating assembly 31 is located in the cavity at a position between the outlet vents 33 and the base fan 32.

In other embodiments of the present invention, the upper tray and the lower tray form the cavity by means of magnetic attraction. Those skilled in the art will know how to implement this, and will not be described in detail here.

The air guide portion 34 is provided at a position of the upper tray 35 adjacent to the air outlet 33. The air guide portion 34 has a shape with a high front and a low rear, or at least has a shape with a high front and a low rear as a whole. Preferably, the air guide part 34 is a comb structure, which guides air and simultaneously facilitates combing and brushing a soft brush head, and makes air flow fully contact with the brush head, thereby greatly improving drying/air-drying efficiency.

Fig. 3 and 4 illustrate one embodiment of the surface cleaning system of the present invention, which is exemplified as a pool robot. This shows the situation where the main unit is replaced on the base after the completion of the pool cleaning.

As shown in fig. 4, the pool robot provided by the present invention includes a main frame assembly 40 and a roll brush 42. The main assembly 40 includes a top water outlet 41, a water inlet 43, a main pump 44, a filter assembly 45, and a drive motor (not shown).

Figures 5 and 6 show another embodiment of the surface cleaning system of the present invention, which is illustrated as a scrubber. It shows the situation where the main unit is replaced in the base after the floor cleaning is completed.

As shown in fig. 5, the present invention provides a floor washing machine including a main assembly 10, a floor brush assembly 20, and a base 30. Wherein the host assembly 20 comprises a handle 13, a mode button 14, a sewage tank 17, a clean water tank 15, a water valve 12 (not shown), a main body motor 11, a main control board (not shown) and an air duct 16; the mode key 14 is electrically connected to the main control board.

Compared with the prior art, the floor washing machine with the comb tooth structure air guide part shortens the drying time by 60 percent under the same wind speed by the inventor through a comparison test. And because of the improvement of the drying efficiency, the upper tray of the base does not need to be provided with a concave cleaning groove for receiving water, so that the breeding of bacteria and the generation of peculiar smell are further reduced, and the base is healthier and more environment-friendly.

In the present invention, the bottom of the air outlet 33 is higher than the bottom of the upper tray, preferably higher than the front end of the air guiding part, as shown in fig. 1. This design prevents on the one hand that sewage from getting into the air outlet, is favorable to improving wind-guiding efficiency on the one hand. In the prior art, a plurality of complicated settings are provided, the efficiency is not high, and the invention has simple and effective structure and practical value.

In the present invention, the heating assembly 31 is located in the cavity between the upper tray 35 and the lower tray 36, and is preferably a PTC heating assembly.

In further embodiments of the present invention, the heating assembly has a temperature control element.

Preferably, the heating assembly is not arranged right below the air guide part. As shown in fig. 4 and 8, in some embodiments of the present invention, the heating unit 31 is disposed at a position slightly distant from a position just below the air guide part, and the position is offset from a portion of the upper tray supporting the roller brush. This design is for heating safety considerations. Compared with the prior art, a plurality of schemes directly arrange the heating assembly under the corresponding rolling brush, and the schemes have potential safety hazards and need to be designed for ensuring safety. The invention realizes the balance of safety and efficiency by using a simple structure because of high air guide efficiency.

Some embodiments of the invention provide a floor brush assembly comprising a wiper strip, a roller brush, a water pump and a drive motor. As shown in fig. 7, in some embodiments of the present invention, the wiper strip 24 is disposed in front of the roller brush 23, preferably directly in front of the roller brush 23. During self-cleaning, the rolling brush 23 rotates clockwise, the scraping strip 24 scrapes off dirt on the rolling brush, and the angle of the scraping strip prevents the scraped dirt from entering the air outlet 33.

In some embodiments of the present invention, the air duct 16 connects the waste tank 17 and the floor brush assembly 20. The water valve is arranged to cooperate with the water pump to spray water from the clean water tank to the roll brush.

The sewage tank is provided with a detachable filter assembly, preferably a HEPA filter screen.

The surface cleaning system of the invention has energy-saving and high-efficiency self-cleaning drying function, and comprises:

a self-cleaning mode for cleaning the roll brush;

a main machine drying mode for drying the main machine air duct and the filtering component; and

and a rolling brush drying mode for drying the rolling brush.

In some embodiments of the invention, a roller brush air drying mode is further included for air drying the roller brush.

In the self-cleaning mode, a main body motor and a water valve in the main machine assembly are started, and a driving motor and a water pump in the floor brush assembly are started, so that water in the clean water tank is sprayed onto the rolling brush through the water valve and the water pump.

In some embodiments of the present invention, the roller brush rotates with the operation of the driving motor, and dirt on the roller brush enters the sewage tank through the air duct under the dual actions of the scraper bar and the main body motor.

As shown in fig. 10, in some embodiments of the present invention, the self-cleaning mode includes:

Wherein the third rotational speed is greater than the first rotational speed and the second rotational speed, preferably substantially greater than the first and second rotational speeds. The first and second rotational speeds may be the same or different.

In the self-cleaning mode of the present invention, neither water supply nor suction is initiated, while the roll brush is kept rotating for a certain time. During this time, the water-soaked roll brush is cleaned by the action of the wiper strip. The inventors have found that such a design improves the efficiency of self-cleaning and also saves water.

In other embodiments of the present invention, as shown in fig. 11, the self-cleaning step is a deep self-cleaning mode including:

s130, the roller brush rotates at a third rotating speed for a third time, and meanwhile, the main body motor sucks water thrown out by the roller brush into the sewage tank through the air channel at a first gear.

Wherein the third rotational speed is greater than the first rotational speed and the second rotational speed, preferably much greater than the first and second rotational speeds, e.g. an order of magnitude higher. The first and second rotational speeds may be the same or different. The sixth rotational speed is greater than the fourth rotational speed and the fifth rotational speed, preferably much greater than the fourth rotational speed and the fifth rotational speed, for example, by one order of magnitude. The fourth and fifth rotational speeds may be the same or different.

The power of the second gear may be the same as or different from the power of the first gear. The sixth time is greater than the third time, e.g., an order of magnitude higher.

In this mode, there are two puffs, the second for a greater time than the first. This is because the inventors consider that when suction is applied, noise is large. If it is used for a long time for the first time, the user is scared by sudden noise. Through the design, the whole using process can be more humanized. And the roller brush is cleaned during the first suction, the roller brush is cleaned during the second suction, the time is long, and the whole pipeline, including the filtering component, is cleaned.

FIG. 9 illustrates an air duct in another embodiment of the surface cleaning system of the present invention, which is exemplified by a pool robot. It shows the situation where the main unit is replaced on the base after the completion of the pool cleaning.

The pool robot includes a roller brush 42 and a host assembly 40. The top nozzle 41 is located at the top of the main unit assembly. The host assembly 40 includes a host pump 44, a filter assembly 45 (e.g., a dirt box). The pool robot has a water inlet 43 at the bottom and an outlet 41 at the top.

When the swimming pool robot is placed on the base after working, the swimming pool robot can complete the process from cleaning the rolling brush to cleaning the filtering component and the pipeline and sucking dirt into the sewage tank by only externally connecting the clean water tank and the sewage tank, thereby realizing the self-cleaning effect. The arrows in fig. 9 illustrate the flow of air within the surface cleaning system during the drying step, forming a wind tunnel. It will be appreciated by those skilled in the art that during the self-cleaning step, the airflow will at least have a similar course to that from the roller brush 42 to the top outlet 41. In the self-cleaning-drying process, the water inlet and the water outlet in the main machine assembly also serve as the functions of the air inlet and the air outlet. The external sewage tank is connected with the water outlet 41.

After self-cleaning, hot air generated from the base is blown out from the air outlet 33, is discharged from the top water outlet 41 through the rolling brush 42, the water inlet 43, the filtering component 45 and the main machine pump 44, and can dry the rolling brush 42, the filtering component 45 and the interior of the machine body, so that the filtering component and the pipeline in the machine body are prevented from breeding bacteria and mildewing.

Whether an external motor is needed depends on whether the selected host pump can meet the design requirements of the invention, and a person skilled in the art can determine the external motor according to specific conditions.

In the self-cleaning mode of the present invention, the first, second, third, fourth, fifth, and sixth rotational speeds and the operating time, and the operating parameters of the first gear and the second gear may be parameters preset in the main control system. Of course, it is fully understood by those skilled in the art that the real-time adjustment/setting can be performed by the main control system according to the detected condition of the rolling brush, as long as the basic logic meets the design logic of the inventor.

In some embodiments of the present invention, the host control systems of the base and the host components may be configured separately to accommodate different host situations. The user can pair the base with the host parameters on the App.

In the mainframe drying mode according to some embodiments of the present invention, the water valve and the water pump are turned off, the main body motor and the driving motor are kept running, the heating assembly and the base fan are turned on, and under the combined action of the main body motor and the base fan, the airflow is heated by the heating assembly, passes through the air duct and the sewage tank, and is finally discharged by the main body motor.

In the rolling brush drying mode, the main body motor, the water valve and the water pump are in a closed state, and the driving motor, the heating assembly and the base fan are in an operating state; the round brush is at the uniform velocity, and under base fan and heating element's effect, moisture on the round brush evaporates fast, reaches the fast drying effect.

In the rolling brush air drying mode, a main body motor, a water valve, a water pump and a heating assembly are in a closed state, and a driving motor and a base fan are in an operating state; the rolling brush rotates at a constant speed, and the hair of the rolling brush is gradually dried until the hair is completely dried under the action of the base fan.

From the perspective of a user, the rolling brush and the pipeline can be automatically cleaned by one key. After cleaning, hot air drying is started, full-channel efficient drying is initiated, the rolling brush, the pipeline, the filter screen and the sewage tank can dry and remove peculiar smell, and stains are prevented from being left to generate mould.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the idea of the present invention.
