The floor brush 200 has a wet mopping function, and wet mopping of the surface to be cleaned can be performed by wetting the surface to be cleaned or wetting cleaning members, such as a drum, a mop, etc., on the floor brush 200. The user can operate the host 100 to control the moving direction of the floor brush 200.

The host 100 includes a housing 110, a dust collection assembly 120, and a hot air outlet assembly 130, where the dust collection assembly 120 and the hot air outlet assembly 130 are disposed in the housing 110.

The hot air outlet assembly 130 can be communicated with the dust collection assembly 120, and air flow generated during operation of the dust collection assembly 120 is utilized to blow the wetted surface to be cleaned and heat the air flow so that the wet and towed ground can be dried quickly.

In some embodiments, the dust collection assembly 120 includes a dust collection fan, the housing 110 has an air outlet duct 111 in communication with an air outlet side of the dust collection fan, and the air outlet duct 111 extends toward an end of the main unit 100 facing the floor brush 200 and forms an air outlet 112.

In addition, since the heating element 131 is blocked in the air outlet duct 111, the heat exchange efficiency of the air flow between the heating element 131 and the air outlet duct 111 is higher, so that the air flow at the air outlet 112 has a higher temperature, and the cleaning effect of water stains is improved.

The structure of the air outlet duct 111 and the specific installation position of the heat generating element 131 will be described in detail.

Referring to fig. 1 and 2, in one possible implementation, an end of the host machine 100 may be movably connected to a rear end of the ground brush 200 in the advancing direction, and the host machine 100 may rotate relative to the ground brush 200, so as to facilitate controlling the advancing direction of the ground brush 200. The dust absorption fan can set up the one end that keeps away from the floor brush 200 on the host computer 100, and air-out wind channel 111 can extend along the length direction of host computer 100, and wherein, air-out wind channel 111's first end communicates with dust absorption fan's air-out side, and air-out wind channel 111's second end is located the one end that the host computer 100 is close to floor brush 200, and air-out 112 forms in air-out wind channel 111's second end.

It can be appreciated that the heating element 131 may be disposed at one end of the air outlet duct 111 near the air outlet 112, that is, the heating element 131 may be disposed at the second end of the air outlet duct 111, so that the air flow heated by the heating element 131 can be blown out from the air outlet 112 as soon as possible, and the flow path of the hot air from the air outlet duct 111 to the surface to be cleaned is shortened, so that the temperature of the air flow blown out from the air outlet 112 can be increased, and the temperature of the heated air flow is prevented from being reduced. In this way, the air flow blown to the surface to be cleaned has a higher temperature, and the drying efficiency is improved.

In some embodiments, the air outlet 112 may be located at the rear of the travelling direction of the floor brush 200, so that the air flow blown out from the air outlet 112 may face the floor surface cleaned by the floor brush 200, and thus, after the floor brush 200 is wet-towed, the air flow blown out from the air outlet 112 may immediately dry the clean and wet floor surface cleaned by the floor brush 200, so as to prevent slipping or secondary pollution.

It should be noted that, the heat generating element 131 may occupy at least a part of a ventilation section in the air outlet duct 111, and when the air flow flows through the air outlet duct 111, the heat generating element 131 contacts, and the heat generating element 131 transfers heat to the air flow to heat the air flow.

In addition, the heating element 131 may adopt an electric heating mode, and the heating temperature of the heating element 131 may be adjusted according to the magnitude of the current, however, other heating modes may also be adopted for the heating element 131, which is not particularly limited in the embodiment of the present utility model.

It is understood that the fixing bracket 132 may be detachably connected to the inner wall of the air outlet duct 111, including but not limited to a threaded fastener connection, a snap connection, etc. Alternatively, the fixing bracket 132 may be connected to the air outlet duct 111 by welding, bonding, or the like, which is not particularly limited in the embodiment of the present utility model.

Illustratively, the heat generating member 131 may be detachably mounted on the fixing bracket 132, and the outer profile shape of the fixing bracket 132 may be matched with the ventilation cross-sectional shape of the air outlet duct 111, and when the air flows through the air outlet duct 111, the air flows may pass through the circumferential side or the inside of the heat generating member 131.

In some embodiments, the heat generating element 131 may be blocked in the air outlet duct 111, so that the heat generating element 131 has enough coverage in the air outlet duct 111, so that the air flow flowing through the air outlet duct 111 can be heated by the heat generating element 131 as much as possible, and the heating efficiency of the air flow is improved.

It is understood that the side wall of the heat generating element 131 may extend along the flowing direction of the air flow, so that the side wall of the heat generating element 131 may guide the air flow, and the air flow may sufficiently contact with the side wall of the heat generating element 131 when the air flow passes through the heat generating element 131.

In the embodiment of the present utility model, the shape of the groove wall of the accommodating groove 1321 is matched with the outline of the outer wall of the heating element 131, and the groove wall of the accommodating groove 1321 is adhered to the outer wall of the heating element 131, and the operating notch 1322 communicated with the groove opening is formed in the groove wall of the accommodating groove 1321, so that the reliability and stability of the installation of the heating element 131 in the accommodating groove 1321 can be improved.

It can be appreciated that when the heat generating component 131 needs to be installed or replaced, the heat generating component 131 can be inserted and removed through the operation notch 1322. The outer wall of the fixed support 132 can be tightly attached to the inner wall of the air outlet channel, so that the occupation of the fixed support 132 to the inner space of the air outlet channel is reduced, the ventilation sectional area as large as possible is reserved, and the airflow circulation efficiency is improved.

For example, the fixing bracket 132 may have a first clamping portion 1323, the first clamping portion 1323 extends to the outside of the bottom of the accommodating groove 1321, and the inner wall of the air outlet duct 111 may be provided with a second clamping portion 113, where the first clamping portion 1323 is clamped with the second clamping portion 113, so that the fixing bracket 132 may be fixedly installed in the air outlet duct 111, and the reliability of the installation of the hot air outlet assembly 130 in the air outlet duct 111 is improved.

One end of the first clamping portion 1323 connected to the fixing bracket 132 may be in an "L" structure, and the first clamping portion 1323 extends a certain distance toward the middle of the fixing bracket 132, so when the heating element 131 is located in the accommodating groove 1321, one end of the heating element 131 may abut against the first clamping portion 1323, and the other end of the heating element 131 may be fastened and fixed by the third clamping portion 1324.

It should be noted that, the two ends of the heating element 131 along the extending direction of the air outlet channel can be respectively limited and fixed by the first clamping portion 1323 and the third clamping portion 1324, so that the two ends of the fixing bracket 132 along the extending direction of the air outlet air duct 111 can be penetrated, and the space occupation of the through openings at the two ends is reduced, which not only can ensure the installation stability and reliability of the heating element 131, but also can ensure that the air outlet air duct 111 has good airflow circulation efficiency.

Referring to fig. 1 to 7, in some embodiments, the number of the third clamping portions 1324 may be at least two, the at least two third clamping portions 1324 are respectively disposed on two opposite sides of the accommodating groove 1321 in the first direction, and the positions of the at least two third clamping portions 1324 in the second direction are staggered, where the first direction and the second direction are perpendicular to each other, and the first direction and the second direction are both perpendicular to the extending direction of the air outlet duct 111, so that the heat generating element 131 has a plurality of stress positions on the fixing bracket 132, which improves the installation stability of the heat generating element 131, and avoids affecting the circulation of the air flow.

Each third clamping portion 1324 is provided with a buckle protruding towards the middle of the fixing bracket 132, and is abutted with the end part of the heating element 131 through a clamping hook, so that the limiting and fixing functions are realized.

Since the heating member 131 is required to continuously generate heat when the cleaning apparatus 10 is in operation, the fixing bracket 132 is required to bear the high temperature generated by the heating member 131 when the fixing bracket 132 is used for mounting the heating member 131, the fixing bracket 132 may be a heat-resistant bracket, and the heat-resistant temperature of the fixing bracket 132 ranges from 70 ℃ to 110 ℃, thereby preventing the fixing bracket 132 from aging when the heating member 131 generates heat.
