[0057] In an embodiment of the present disclosure, referring to Figure 1 , the walking direction of the floor brush assembly 1 is defined as the front direction, and the steam spray plate 20 is arranged on the front side of the floor brush assembly 1. During operation, the floor brush assembly 1 walks forward, and the steam spray plate 20 first sprays steam to the working surface in front of the floor brush assembly 1 to preliminarily clean the working surface, and the floor brush assembly 1 walks forward to further clean the area sprayed by the steam, so as to fully clean the working surface.

[0058] In an embodiment of the present disclosure, referring to Figure 1 , the floor brush assembly 1 is provided with a roller brush 11, and the roller brush 11 can rotate on the working surface under the action of a driving device, so as to clean the working surface. The rotation axis of the roller brush 11 is consistent with the axis direction of the walking wheel on the floor brush assembly 1. The floor brush assembly 1 further comprises a detachably connected roller brush cover 12, and the roller brush cover 12 is buckled above the roller brush 11 to protect the roller brush 11. The roller brush cover 12 can be arranged in an arc-shaped structure matched with the shape of the roller brush 11. In detail, the roller brush cover 12 extends from the upper side of the rear side of the roller brush 11 to the top of the roller brush 11, and then extends to the front side of the roller brush 11.

[0059] In a specific embodiment of the present disclosure, the steam spray plate 20 extends along the axis direction of the roller brush 11, and the first spray holes 201 and the second spray holes 202 are distributed along the extension direction of the steam spray plate 20, so as to increase the coverage range of the steam when the floor brush assembly 1 walks forward.

[0060] In an embodiment of the present disclosure, referring to Figure 1 , Figure 4 , the steam generator 23 and the control valve 24 are arranged behind the roller brush 11 and in the inner cavity of the floor brush assembly 1. The floor brush assembly 1 is provided with a first steam outlet 25 directly connected to the steam generator 23, and a second steam outlet 26 connected to the control valve 24. When the roller brush cover 12 is installed in place, the first steam outlet 25 is in butt joint and communication with the first channel 21, and the second steam outlet 26 is in butt joint and communication with the second channel 22.

The safety valves 3 are configured to open the first steam outlet 25 when the first channel 21 is connected to the first steam outlet 25, and to open the second steam outlet 26 when the second channel 22 is connected to the second steam outlet 26.

[0062] In detail, the safety valve 3 includes a valve chamber 30 and a valve core 31 disposed in the valve chamber 30 via an elastic device 32. The valve core 31 closes the valve chamber 30 under the action of the elastic device 32, that is, closes the first steam outlet 25 and the second steam outlet 26. The first channel 21 is connected to the first steam outlet 25 via a connector, and the second channel 22 is connected to the second steam outlet 26 via a connector. Both the connectors of the first channel 21 and the second channel 22 are provided with a pin structure. When connected to the first steam outlet 25 and the second steam outlet 26, the pin structure cooperates with the safety valve 3 and overcomes the force of the elastic device 32 to push the valve core 31 to move, thereby opening the valve chamber 30, opening the first steam outlet 25 and the second steam outlet 26, and supplying steam to the first channel 21 and the second channel 22.

[0063] When the user manually disassembles the roller brush cover 12, the pin structure of the first channel 21 and the pin structure of the second channel 22 disengage from the corresponding safety valve 3. Under the action of the elastic device 32, the valve core 31 of the safety valve 3 is driven to close the valve chamber 30, preventing steam from being discharged from the first steam outlet 25 and the second steam outlet 26, so as to avoid scalding people with high temperature steam and improve the safety of the cleaning equipment.

[0064] In one embodiment of this disclosure, reference is made to Figure 5 , Figure 6 The floor brush assembly 1 is also equipped with a light assembly 4, which is configured to emit light in different light-emitting modes when the first nozzle 201 emits steam and when the first nozzle 201 and the second nozzle 202 emit steam simultaneously.

The lighting assembly 4 includes an outer frame and multiple lamp tubes mounted on the outer frame. The position and number of lamp tubes can be set to correspond to the first spray hole 201 and the second spray hole 202. Each first spray hole 201 and second spray hole 202 has a corresponding lamp tube. The control lines and power lines of the lamp tubes can be set to be the same as the air path layout of the corresponding spray hole, referring to the layout of the first spray hole 201, the second spray hole 202, and the inner channels 203 and 204 of the first plate.

[0066] When the first nozzle 201 and the second nozzle 202 spray steam, the corresponding lamp is lit, otherwise the corresponding lamp is off. The lighting modes include a burst lighting mode and a uniform lighting mode. In the burst lighting mode, the first nozzle 201 sprays steam, and the lamp corresponding to the first nozzle 201 is lit; in the uniform lighting mode, the first nozzle 201 and the second nozzle 202 spray steam, and all the lamps corresponding to the first nozzle 201 and the second nozzle 202 are lit. When the steam spray plate 20 switches between the burst mode and the uniform mode, the lighting assembly 4 can switch between the two lighting modes instantaneously or gradually.

[0067] The present disclosure also provides a steam assembly, which can be applied to cleaning equipment such as a steam mop, a steam cleaning robot, an ironing machine, etc. The steam assembly includes a steam spray plate 20, which is provided with at least one first nozzle 201 and a plurality of second nozzles 202 for spraying steam onto a working surface, and further includes a first channel 21 for providing steam to the first nozzle 201, and a second channel 22 for providing steam to the second nozzle 202. The steam assembly 2 is configured to provide steam to the first nozzle 201 through the first channel 21, or to provide steam to the first nozzle 201 and the second nozzle 202 through the first channel 21 and the second channel 22 simultaneously. The specific structure and principles of the steam assembly of the present disclosure can be referred to the steam assembly in the above cleaning equipment, and the present disclosure will not be repeated again.

[0068] The technical solutions adopted by the present disclosure will be described below in combination with specific application scenarios to help understanding. In the following application scenarios, a mop is taken as an example.

[0069] Application scenario one

[0070] During the working process of the mop, the floor brush assembly 1 walks forward, and the steam spray plate 20 first sprays steam onto the working surface in front of the floor brush assembly 1 to preliminarily clean the working surface, and the floor brush assembly 1 walks forward to further clean the area sprayed with steam, so as to fully clean the working surface. The steam assembly has a uniform mode with a larger cleaning range and more uniform steam, and a burst mode with a concentrated cleaning range and greater cleaning force. In the uniform mode, the control valve 24 of the steam assembly 2 is opened, the steam generator 23 directly provides steam to the first nozzle 201 through the first channel 21, and provides steam to the second nozzle 202 through the second channel 22, so that the number of nozzles spraying steam is relatively large, and the steam pressure of each nozzle is relatively small and uniform. In the burst mode, the control valve 24 is closed, and the steam generator 23 only provides steam to the first nozzle 201 through the first channel 21, so that the steam pressure is relatively large, and the cleaning force on the working surface is greater. The first nozzle 201 participates in steam spraying in both the burst mode and the uniform mode, which can reduce the total number of nozzles, and is conducive to reducing the size of the steam spray plate and reducing costs.
