This invention provides an oral cleaning device and its control method. The oral cleaning device includes a first pressure detection area and a second pressure detection area spaced apart from the first pressure detection area. The control method includes: acquiring first pressure information of the first pressure detection area and second pressure information of the second pressure detection area; determining a shielding state of the first pressure detection area based on the second pressure information; the shielding state includes a shielded state and an unshielded state; when the first pressure detection area is triggered, if the shielding state is unshielded, determining whether to execute a target action based on the first pressure information; if the shielding state is shielded, not responding to the triggering state action of the first pressure detection area. This invention, by combining the detection and processing of the pressure status of the second pressure detection area, can shield the triggering of the first pressure detection area, reducing false triggering of the oral cleaning device.

The invention relates to a lubricant guide housing (32) for being arranged in the region of a hydrodynamic torque converter, comprising a radially extending first section (33) which is arranged for axially opposite positioning to one end face (35) of the torque converter (9) in the installed state of the lubricant guide housing (32). The first section (33) transitions radially outwardly into an axially extending second section (34) which is configured for axially at least partially and radially outwardly surrounding the torque converter (9) starting from the first section (33) in the installed state of the lubricant guide housing (32). In order to realize a lubricant guide housing by means of which an excessive accumulation of lubricant in the region of the hydrodynamic torque converter can be reliably prevented, both the first section (33) and the second section (34) are configured to be completely annular.

The application discloses a shielded RJ45 connector and an assembling equipment thereof, and belongs to the field of connectors. The connector comprises a first shield and a second shield, a first shield is arranged between any two adjacent terminal assemblies, the first shield is used for shielding the terminal assemblies adjacent in the horizontal direction, a second shield is arranged between the two terminal assemblies in each pair, the second shield is used for shielding the terminal assemblies adjacent in the vertical direction, the shield between the adjacent terminals is realized, the crosstalk between the terminals is reduced, and the transmission stability of the connector is ensured. In the assembling equipment, two mechanical hands are used for clamping the insulating seat and the shield shell, a pressing plate is used for positioning the bent part by pressing, a bending assembly is used for pre-bending to determine the bending position, and the bending position is bent twice, so that the accuracy and consistency of the bending are effectively ensured, and the machining precision and assembling precision of the shield shell are improved.
