Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 10, which is a preferred embodiment of the present invention, in this embodiment, the brush head module 01 for a cleaning machine includes a housing 1, a brush head 13, and an ozone passage 16. The housing 1 has a wind guide channel 11 therein, the wind guide channel 11 has a dust suction port 111 with a downward opening and an air outlet 113 in fluid communication with the dust suction port 111, along the airflow path, the air outlet 113 is located at the downstream of the dust suction port 111, so that the dust suction port 111, the wind guide channel 11 and the air outlet 113 form a complete dust suction flow channel. In this case, the upstream section and the downstream section of the air guiding channel 11 do not necessarily have the same flow direction, and actually, since the orientations of the dust suction opening 111 and the air outlet 113 in actual production are often opposite, for example, the dust suction opening 111 is usually disposed downward to facilitate suction of dust on the surface of a bottom surface, a table top, etc., and the air outlet 113 is usually disposed upward or laterally to facilitate air exhaust. Therefore, in order to match the design of the dust suction opening 111, the air guide channel 11 in the embodiment is arranged in the upstream section substantially vertically or at a slight angle to the vertical; in order to adapt to the design of the air outlet 113, the air guiding channel 11 is substantially horizontal or slightly angled from horizontal in the downstream section.

Of course, in order to achieve the dust suction function, other structures are needed to realize the following functions in combination with the brush head module 01: in the cleaning machine, a fan 4 and a separation module 3 for separating the mixture of water and dust are also included, along the airflow path, the separation module 3 is positioned between the brush head module 01 and the fan 4, the inlet of the separation module 3 is in fluid communication with the air outlet 113 of the brush head module 01, and the outlet of the separation module 3 is in fluid communication with the inlet of the fan 4. The cleaning machine in this embodiment is a dust collector or a sweeping robot, and may also be similar cleaning equipment, which is not limited herein.

In this embodiment, the brush head 13 is used for cleaning the object to be cleaned, and the brush head 13 is disposed at the dust suction port 111 of the air guide channel 11. The brush head 13 here may be a fixed brush, or other movable brush heads such as a rolling brush, and in this embodiment, a disc brush is used, and the disc brush realizes cleaning in a rotating manner, and the rotation axis of the disc brush extends vertically to ensure the maximum contact area with the surface to be cleaned, thereby improving the cleaning effect.

In the present embodiment, the ozone channel 16 is opened on the housing 1 and has an ozone nozzle 161, and the ozone nozzle 161 is used to provide ozone to the air guide channel 11 and the dust suction port 111 to achieve the sterilization function during cleaning. In this embodiment, the ozone nozzle 161 is connected to the dust suction port 111. Therefore, the ozone nozzle 161 and the dust suction port 111 are communicated, when the cleaner is in a dust suction state, the ozone can be sucked out of the ozone nozzle 161 by negative pressure generated by airflow flowing, the conveying of the ozone to the dust suction port 111 can be realized without an additional power source, meanwhile, the conveying of the ozone can also be synchronously stopped along with the stopping of the cleaner, the ozone is further ensured not to leak, and the purposes of dust removal and sterilization are realized on the premise of safety and convenience.

Although the negative pressure generated by the airflow can suck the ozone out of the ozone nozzle 161, because the airflow is generated continuously, once the power of the fan 4 is high, the ozone at the ozone nozzle 161 stays on the surface to be cleaned only for a short time or even does not stay, and may be sucked away, thereby causing unsatisfactory cleaning effect. Therefore, the design of the ozone nozzle 161 can be varied, and different ozone injection modes can greatly affect the sterilization effect. For example, the ozone nozzle 161 can be designed to be aligned with the surface to be cleaned and sprayed, so that the surface to be cleaned can be impacted by the self impact of ozone while providing ozone, so as to play a role of flushing, and thus, more stubborn impurities can be removed.

To balance the cleaning and disinfecting effects and the prevention of leakage, the ozone jets 161 in this embodiment are arranged toward the head 13. The ozone nozzle 161 is designed in the direction, so that the ozone conveyed by the ozone nozzle is sprayed on the brush head 13, and on one hand, the ozone leakage caused by directly spraying ozone on the ground is avoided (because the brush head 13 is arranged in the dust suction port 111, the sprayed ozone is directly sucked away by the suction force transmitted to the dust suction port 111 by the air guide channel 11, the whole process is realized at the dust suction port 111, and the influence of the movement of the cleaning machine is avoided); on the other hand, because the brush head 13 is in a state of rotating at a high speed in the work process, the ozone spraying mode can scatter the ozone at the ozone nozzle 161 and can centrifugally throw out the ozone attached to the brush head 13, so that the ozone is ensured to be filled in the dust suction port 11 and the air guide channel 11 to the maximum extent on the premise of no leakage of the ozone, and further, all parts of the surface to be cleaned can have good sterilization effect.

In this embodiment, the center line of the ozone nozzle 161 intersects with the surface to be cleaned, and the ozone nozzle 161 includes at least a first nozzle 1611 and a second nozzle 1612 arranged in sequence along the ozone spraying direction, wherein the first nozzle 1611 and the second nozzle 1612 are communicated. The design of two spouts intercommunication like this, when one of them spout sprays, can provide power for another spout, take out another part ozone from this spout, two spouts complement each other for ozone fluid sprays more brute force, has good sterilization dust removal effect. In addition, since the pressure at the downstream nozzle is large, most of the ozone will be sprayed from only one outlet when the two diameters are out of balance, and the other nozzle has only a small amount of ozone, so that it is difficult to achieve the mutual gain effect, therefore, in this embodiment, the diameter of the second nozzle 1612 is not larger than the diameter of the first nozzle 1611. The ozone in the ozone channel 16 can be an external ozone source, but in this embodiment, the brush head module 01 further includes an ozone generating device 17, and an outlet end of the ozone generating device 17 is communicated with an inlet end of the ozone channel 16.

The bottom of the valve core 182 is located in the air guide passage 11, and can move downward relative to the valve chamber 18a under the negative pressure of the air guide passage 11. Furthermore, an elastic member 19 is included, the elastic member 19 acting on the spool 182 such that the spool 182 always has a tendency to move upward, and the elastic member 19 is in a charged state in a state where the spool 182 is in a downward movement. The switching design of ozone passageway 16 further makes the transport of ozone bind with the operating condition of cleaning machine like this, and the fan 4 during operation of cleaning machine promptly, ozone just can realize carrying, otherwise then stops carrying, and then has cut off the supply of ozone in the source, cooperates the position design of ozone spout 161 and brush head 13 mentioned above, forms "dual fail-safe", ensures that ozone can not leak.
