Each pair of shoes can only use the cleaning unit in the shoe cleaning and protecting all-in-one machine, also can only use the nursing unit in the shoe cleaning and protecting all-in-one machine, and also can use the cleaning unit and the nursing unit in the sub cleaning and protecting all-in-one machine at the same time, and the specific operation is determined according to the cleaning and protecting program determined by the exclusive information of each pair of shoes.

It can be understood that the cleaning unit and the nursing unit can be arranged in the shoe washing and nursing all-in-one machine in the structure of the upper layer and the lower layer, and can also be arranged in the shoe washing and nursing all-in-one machine in a front-back mode.

For example, if the shoes only need to be cleaned or nursed, the shoes are transferred to the cleaning unit or the nursing unit through the transfer module; if shoes need wash simultaneously and nurse the operation, then set up in shoes washing protects all-in-one when the structure of the upper and lower floor of cleaning unit and nursing unit, convey the shoes to cleaning unit earlier through transfer module, after shoes wash, convey the shoes to nursing unit by the elevation structure between cleaning unit and the nursing unit, wash and protect all-in-one with the front and back mode at shoes when cleaning unit and nursing unit and place in shoes, convey the shoes to cleaning unit earlier through transfer module, after shoes wash, convey the shoes to nursing unit by the toggle structure between cleaning unit and the nursing unit.

On the basis of the embodiment, the shoe washing and protecting all-in-one machine further comprises an outlet conveying module; the outlet transmission module is connected with the washing and protecting module;

the outlet transmission module is used for transmitting the shoes which are subjected to the operation corresponding to the washing and nursing program to a shoe cabinet.

Specifically, the outlet transmission module can be connected with the shoe cabinet and used for transmitting the shoes after the washing and protecting operation is finished, the shoes are automatically transmitted to the corresponding shoe cabinet, and the experience of a user is improved.

It should be noted that the conveying module and the outlet conveying module are used for moving the shoes from the shoe washing and protecting all-in-one machine to the shoe washing and protecting all-in-one machine, and the specific structures of the conveying module and the outlet conveying module can be realized by depending on the existing conveying and moving mechanism.

The working principle of the shoe washing and protecting integrated machine is as follows:

after the shoes are put into the entrance of the shoe washing and protecting all-in-one machine, the exclusive information such as the material and the nursing requirement of the shoes is acquired through the detection module, and the exclusive information is fed back to the control module. Meanwhile, a conveying module is arranged at the inlet of the washing and protecting integrated machine, the conveying module comprises a lifting structure or a shifting structure which is connected with the detection module and used for washing and protecting the module, and the lifting structure or the shifting structure is responsible for sending shoes into the washing and protecting module from the detection module. After the control module receives the exclusive information, the control module determines the washing and protecting program of the shoe according to the exclusive information, the washing and protecting module carries out the dust removal, oiling and waxing, deodorization and other nursing operations on the shoe through the nursing unit according to the washing and protecting program, the cleaning unit carries out the cleaning operations of automatically matching a detergent, selecting the washing program and the like, and finally the shoe is dried and pushed out and is sent to the outlet conveying module of the washing and protecting all-in-one machine so as to send the shoe to the shoe cabinet through the outlet conveying module.

Fig. 2 is a flowchart of a control method of the shoe washing and caring all-in-one machine according to an embodiment of the present invention, which is applicable to a case where the shoe washing and caring operation is automatically completed. The method specifically comprises the following steps:

s210, acquiring exclusive information of the shoe through a detection module, and feeding the exclusive information back to a control module connected with the detection module.

The mode that the detection module acquireed the exclusive information of shoes can be for through the mode of scanning shoes bar code, also can shoot shoes through the camera, later by control module and server communication to shoes search to acquire the exclusive information about shoes on the net, for example can wash, washing temperature, washing agent type and quantity, exclusive information such as material.

S220, determining a washing and protecting program of the shoe according to the exclusive information received by the control module.

For example, for washable shoes, proper temperature, time and detergent dosage can be set according to information obtained from an official website or an online shopping mall, and then a drying or air-drying mode is set according to material information to generate a shoe cleaning program; for shoes such as unwashable leather shoes and the like, basic cleaning can be carried out by using a rolling brush, and then shoe polish care is carried out according to the colors of the shoes so as to generate a shoe care program.

And S230, controlling a washing and protecting module to execute the operation corresponding to the washing and protecting program on the shoe based on the received washing and protecting program.

On the basis of the above embodiment, the washing and caring program comprises a washing program and/or a caring program; optionally, the controlling, washing and protecting module executes an operation corresponding to the washing and protecting program on the shoe based on the received washing and protecting program, including: controlling the washing and protecting module to perform washing operation corresponding to the washing program on the shoe based on the received washing program; and/or controlling the washing and caring module to perform a caring operation corresponding to the caring program on the shoe based on the received caring program.

It can be understood that the benefit of this embodiment is that only need to put shoes and protect all-in-one entrance can, need not the problem of the user's consideration how to wash and nurse, shoes wash and protect all-in-one will automatically accomplish and wash and protect the action.

Furthermore, the shoe washing and protecting all-in-one machine can be connected with a shoe cabinet, the outlet of the shoe washing and protecting all-in-one machine is connected to the shoe cabinet through an automatic outlet transmission module, and the washed and protected shoes are sent into the shoe cabinet to be put.

According to the technical scheme of the embodiment of the invention, the exclusive information of the shoe is obtained through the detection module, and the exclusive information is fed back to the control module connected with the detection module; determining a washing and protecting program of the shoe according to the exclusive information received by the control module; and controlling a washing and protecting module to execute the operation corresponding to the washing and protecting program on the shoe based on the received washing and protecting program. In this embodiment, according to the exclusive information of obtaining waiting to wash shoes, wash the washing and protecting procedure of protecting all-in-one according to the exclusive information of shoes, provide exclusive washing for shoes and protect the scheme promptly for wash shoes more intellectuality, intellectuality.
