A saw blade (100) is annular and includes an external gear (101) arranged on an outer edge and an internal gear (102) arranged on an inner edge, and the external gear (101) is configured for cutting; a drive gear (200), where the internal gear (102) is meshed with the drive gear (200); a transmission assembly (300), where the transmission assembly (300) includes a transmission shaft (301) and a first bevel gear (302), and the drive gear (200) and the first bevel gear (302) are fixedly arranged at two ends of the transmission shaft (301), respectively; an output assembly (400), including an output shaft (401) and a second bevel gear (402) that are fixedly connected, where the first bevel gear (302) and the second bevel gear (402) are meshed with each other for transmission. The advantages of the present invention are as follows: first, by setting a transmission mode in which the internal gear (102) is meshed with the drive gear (200), the original hard friction transmission mode is replaced, thereby improving the transmission performance of the saw blade (100) and overcoming the defect of being prone to slippage; second, the gear (200, 101, 102, 302, 402) transmission mode makes a side press wheel (500) fixed, and no adjustment is required after the saw blade (100) is replaced, thereby reducing the difficulty of replacing and adjusting the saw blade (100) and the press wheels (500), and achieving convenience and efficiency.

Provided are a surface passivation structure for a cut solar cell, a preparation method thereof, a cut solar cell, and a photovoltaic module. The surface passivation structure includes a silicon substrate, where one side or two opposite sides of the silicon substrate are laser-cut surfaces; a front/back surface of the silicon substrate includes a base region located in a central portion and small textured regions located on four side edges; the base region is provided with a boron emitter; a front passivation and anti-reflection layer covers the boron emitter and the small textured regions; surfaces of the boron emitter and the small textured regions are provided with pyramidal textured structures; and a pyramid in the base region has a larger dimension than pyramids in the small textured regions. This application removes pn junctions on a laser-cut edge and a non-laser-cut edge of the cut cell and forms small pyramidal textured structures. This reduces the negative impact of edge carrier recombination on efficiency, lowers the efficiency variation across different positions of the cut cell, and improves the overall efficiency of the cut cell and power of a corresponding module.

An electric WDT distribution tool (WDT) is structurally simple and convenient-to-operate, can realize distribution synchronously during a dosing process, and can be adapted to baskets of different depths. The electric WDT distribution tool (WDT) includes a distributor body (1), where a powder inlet (2) is formed in a middle of the distributor body (1); a distribution module is further provided on the distributor body (1); the distribution module (1) is a vibratory distribution device or a rotary distribution device; the distributor body cooperates with a basket of a coffee maker; and coffee powders fall into the basket through the powder inlet (2), while being distributed by the distribution module.

Disclosed are a cyclone dust absorption system, a cleaning robot, and a dust absorption method. The dust absorption system includes a dust absorption opening (22), a dust collection box (1), a separator (2), and a negative pressure generator (3), where the separator is capable of forming a spiral airflow, using a centrifugal force to separate garbage from the airflow and collecting the garbage in the dust collection box, thereby being capable of replacing a filter net assembly and reducing use costs. Further, an acceleration guide surface (25) is capable of accelerating flow of the spiral airflow, causing a larger centrifugal force to the garbage, and facilitating more thorough and faster separation of the garbage from a separation opening, thereby enhancing an effect of separating the garbage.

Provided are a dust collection base station, a dust cup for a dust collector, a cleaning device and a dust collection method, which belong to the field of cleaning devices. The dust collection base station includes a base station body and a cover opening structure, where an end of the base station body is provided with an accommodating groove; the cover opening structure is located on a side wall of the accommodating groove; and the cover opening structure is configured to trigger unlocking of a dust discharge cover of a dust cup when an air pressure in the accommodating groove is within a preset negative pressure range. During unlocking, since the air pressure in the accommodating groove is within the preset negative pressure range, the air pressure difference between the dust cup and the accommodating groove is within an acceptable range. In addition, the impact generated when the dust discharge cover is opened under the action of the air pressure difference on both sides is also within an acceptable range. Thus, the debris in the dust cup enters the accommodating groove under the action of the air pressure difference between the dust cup and the accommodating groove. This design reduces or even avoids the residue of debris in the dust cup, and avoids impairing the normal operation of the cleaning device due to excessive impact generated when the debris enters the accommodating groove.
