It will be appreciated that in other embodiments the cleaning device 1 may also be a floor washer or a cleaning robot, which is not limited only herein.
Referring to fig. 1 and 6, in a specific embodiment, the cleaning apparatus 1 further includes a stain detection device 19, where the stain detection device 19 is disposed on the machine body 11 and connected to the battery 15 and the controller, and the stain detection device 19 is configured to emit light to the outside of the machine body 11 to detect stains on a surface to be cleaned, when a user needs to find hidden stains on the surface to be cleaned of a fabric product, the stain detection device 19 may be turned on, so that the user can conveniently find hidden stains on the fabric product, and control the liquid spraying port 11C to spray clear water and/or cleaning liquid on the hidden stains, and then the cleaning member 18 disposed at the bottom of the cleaning apparatus 1 can reciprocate on the surface to be cleaned, and recover the liquid carrying the stains into the sewage tank 12 through the stain absorbing port 11A, thereby realizing fixed-point cleaning of the hidden stains on the surface to be cleaned, and improving cleaning efficiency, so as to reduce the probability of bacteria growing on the surface of the fabric product due to long-term residues of the hidden stains; and can use the cleaning solution that the pertinence is stronger to different recessive stains to clear away to improve cleaning quality.
Referring to fig. 1 and 6, in a specific embodiment, the cleaning apparatus 1 further includes a transparent protection member 20, the transparent protection member 20 is connected to the machine body 11, and covers the soil detecting device 19, the soil detecting device 19 is protected by the transparent protection member 20, so that the damage probability of the soil detecting device 19 can be reduced, the service life of the soil detecting device 19 is prolonged, and the light emitted by the soil detecting device 19 is emitted out of the machine body 11 through the transparent protection member 20.
Further, in order to enhance the overall aesthetic appearance of the cleaning apparatus 1, the body 11 has a mounting groove 11D, the stain detection device 19 is disposed in the mounting groove 11D, and the transparent protective member 20 may be disposed at a notch of the mounting groove 11D.
Specifically, the stain detection device 19 is at least one of an ultraviolet stain detection device or a laser stain detection device. For example, when the stain detection device 19 is an ultraviolet stain detection device, for example, an ultraviolet lamp, the wavelength of ultraviolet light emitted by the ultraviolet stain detection device is greater than or equal to 360mm and less than or equal to 370mm, so that when the ultraviolet light emitted by the ultraviolet stain detection device irradiates on pet stains on the surface to be cleaned, a fluorescent reaction is induced on the pet stains, so that a user can find out hidden pet stains according to the fluorescence, and the user can clean the hidden pet stains conveniently. The pet stain includes at least urine and may also include feces, and in order to reduce the effect of the transparent protective member 20 on ultraviolet light, the transparent protective member 20 may be an acrylic lamp cover that is highly transparent to ultraviolet light while being resistant to ultraviolet light. Of course, the stain detection device 19 may be a laser stain detection device for detecting dust stains.
Referring to fig. 1, in a specific embodiment, the stain detection device 19 is disposed on the front side of the machine body 11, so that a user can open the stain detection device 19 to detect stains on the front surface to be cleaned when driving the cleaning device 1 to move forward through the holding portion 114, or can detect stains on the surface to be cleaned through the stain detection device 19 when the user lifts the cleaning device 1 through the holding portion 114.
Specifically, the stain detection device 19 is disposed on the main body 113 and is located on one side of the main body 113 away from the holding portion 114, so that a user can conveniently detect stains on a front surface to be cleaned by using the stain detection device 19 when the user drives the cleaning apparatus 1 to move forward through the holding portion 114, or when the user lifts the cleaning apparatus 1 through the holding portion 114, the main body 113 rotates by taking a hand of the user as a rotating shaft under the action of gravity, and can also detect the stains on the surface to be cleaned by using the stain detection device 19.
Referring to fig. 1, in a specific embodiment, the liquid spraying opening 11C is higher than the surface to be cleaned than the dirt sucking opening 11A, and the dirt detecting device 19 is located between the dirt sucking opening 11A and the liquid spraying opening 11C than the surface to be cleaned, so that the dirt detecting device 19 is closer to the surface to be cleaned, and the light spot of the dirt detecting device 19 on the surface to be cleaned has a larger area, so as to improve the efficiency of finding the dirt by the user.
Referring to fig. 1, further, the distance between the stain detection device 19 and the surface to be cleaned is a first height H1, where the first height H1 is greater than or equal to 26mm and less than or equal to 32mm, so that the stain detection device 19 has a light spot with a larger area on the surface to be cleaned, and the efficiency of searching for stains by the user can be improved. If the first height H1 is smaller than 26mm, the soil detecting device 19 is too close to the surface to be cleaned, resulting in smaller spot area of the soil detecting device 19 on the surface to be cleaned, and lower efficiency of finding the soil by the user. If the first height H1 is greater than 32mm, the stain detection device 19 is further away from the surface to be cleaned, resulting in an excessively large spot area of the stain detection device 19 on the surface to be cleaned, and a weak fluorescence reaction of the induced pet stains, thereby being inconvenient for the user to find the stains.
Referring to fig. 1, in a specific embodiment, the cleaning apparatus 1 further includes a control panel 21, where the control panel 21 is disposed on the machine body 11 and connected to the controller, and is configured to send a control signal to the controller according to a user operation, so that the controller controls the stain detection device 19 to be turned on or off. When the device is used for detecting the hidden stains on the surface to be cleaned by using the stain detection device 19, the control panel 21 can be operated to control the stain detection device 19 to be opened so as to search for the hidden stains by using the light spots irradiated to the surface to be cleaned by the stain detection device 19, so that the cleaning efficiency can be improved; after cleaning is completed, the user operates the control panel 21 to control the soil detecting apparatus 19 to be turned off, so as to reduce the power consumption of the battery 15 and prolong the service life of the soil detecting apparatus 19.
In other embodiments, when the cleaning apparatus 1 is a cleaning robot, the stain detection device 19 may be disposed on the head of the cleaning robot to emit detection light to the surface to be cleaned on the front side of the cleaning robot, and when stains on the surface to be cleaned are detected, the cleaning robot may focus on cleaning the area where the stains are located, such as reciprocating cleaning, or the cleaning robot may bypass the area where the stains are located, so as to avoid the cleaning robot from being stained with an odor. The specific execution action of the cleaning robot may be determined according to the actual situation, and is not limited only herein.
