Description

Technical Field

[0001] The invention relates to accessories for automatically dispensing liquid consumables in a washing machine, and in particular to automatic dispensing of multiple categories of liquid consumables. Background Art

[0002] At present, the liquid consumables of washing machines in the market are mainly put in manually. The disadvantage is that they need to be put in manually every time washing clothes, and the amount of liquid put in depends entirely on personal feeling, which cannot achieve the best ratio of liquid consumables for washing clothes. Washing machines with automatic liquid consumables dispensing function on the market also have one or more liquid refilling container boxes inside the washing machine. Due to the limitation of the structure of the washing machine, the capacity of the container box is too small, and liquid needs to be added frequently during use. After a long time of use, the container box is difficult to clean. Summary of the invention

[0003] The present invention provides a mobile multi-category liquid extraction device, the purpose of which is to simplify the laundry process through the device; users only need to purchase liquid consumables that have been made into standard packaging on the market and install the device in the washing machine to realize the automatic extraction and use of liquid consumables in the laundry process. The device automatically detects the amount of liquid consumables used and gives the user a usage reminder. When the liquid consumables are used up, the user extracts the empty liquid packaging box from the device and reloads a new liquid packaging box to complete the replacement of liquid consumables.

[0004] In order to achieve the above-mentioned objectives, the present invention adopts the following technical scheme: a mobile multi-category liquid pumping device, including a guide rail assembly, a mobile liquid pumping assembly, a control circuit board, a box upper cover, a box lower cover, a liquid packaging box, a water outlet pipe, a water inlet pipe and a joint. The sliding bearing on the mobile liquid pumping assembly is passed through the guide rail of the guide rail assembly, and the two ends of the transmission belt of the guide rail assembly are respectively fixed on the fixed columns on the mobile liquid pumping assembly, and the transmission belt cooperates with the power output shaft of the stepper motor. The rotation of the stepper motor drives the transmission belt to rotate, thereby driving the mobile liquid pumping assembly to move along the guide rail; the upper cover of the box body and the lower cover of the box body are fastened to form an integral box body, the liquid packaging box is placed in the mounting groove of the upper cover of the box body, and the guide rail assembly and the control circuit board are fastened on the upper cover of the box body; one end of the water outlet pipe and the water inlet pipe are respectively fixedly connected to the mixing liquid cavity of the mobile liquid pumping assembly; the stepper motor, the pumping device, the control circuit board, the reset switch and the washing machine are electrically connected; the control circuit board receives relevant instructions of the washing machine, and then controls the stepper motor and the pumping device according to the relevant instruction requirements.
