  • Patent number: 11350806
    Abstract: A handheld vacuum cleaner includes a housing, motor, filter access door, filter, and dirt cup movably coupled to the housing. The housing defines a top, bottom, motor chamber, dirty air inlet, handle, clean air outlet, and air flow path. The air flow path is routed from the dirty air inlet to the clean air outlet. The motor is disposed in the motor chamber and defines a motor axis. The filter access defines a filter chamber with the housing. The filter is disposed in the filter chamber and defines a filter axis. The dirt cup defines a dirt cup axis extending parallel to the motor axis and filter axis. The filter access door is located below the filter axis. When the filter axis door is removed, the filter is removable in a downward direction from the filter chamber.

  • Patent number: 11317707
    Abstract: A brush head for an electric toothbrush includes a support part supporting upper and lower lateral brush elements and transverse brush elements for the combined brushing of the inner, outer and occlusal surfaces of the upper and lower teeth, and an oscillating device intended to impart an oscillating movement to the support part. The support part is elastically deformable such that it can fit snugly against the upper and lower dental arches during brushing. The oscillating device includes a movable part on which the support part is mounted, and a drive shaft coupled to the movable part in order to move the movable part and the support part in an oscillating manner. The movable part extends between the upper lateral brush elements and the lower lateral brush elements.

  • Patent number: 11213936
    Abstract: A torque adjustment switching structure of a torque wrench is characterized by: a screw hole seat, which is located in the rear section of the torque wrench extension shank; the axial actuating sleeve can be axially advanced and retracted; the rear pull sleeve can be forced against the axial actuating sleeve. The axial movement and the rotary motion: the clutch member has a snapping mode and a disengagement mode with the sliding forward and backward of the backward pulling sleeve; and the rearward pulling sleeve presents a force for axial advance and retreat with respect to a screw, and rotates. The timing mechanism is configured to drive the synchronous rotation of the screw. The limiting member is disposed at a corresponding portion of the screw and the rear sliding sleeve to generate a limiting force for the axial backward sliding state of the backward pulling sleeve.

  • Patent number: 11207764
    Abstract: A torque socket tool includes a main body, a driving portion, an abutting member, an axle, and a sleeve member. The main body defines an axial direction. The abutting member is non-rotatably and slidably arranged in the main body. The sleeve member is rotatably sleeved onto the main body. A threaded section drives the abutting member to slide along the axial direction for adjusting the predetermined torque when the axle is rotated by rotating the sleeve member.

  • Patent number: 11161223
    Abstract: A ratchet wrench includes a ratchet unit which has a ratchet tube with a reception hole. A collar is connected to one side of the head and has a slit defined radially through the collar. An engaging member has a first end thereof fixed to the collar, and a second end of the engaging member extends through the slit. The second end of the engaging member is partially located within the through hole of the collar and located above the reception hole of the ratchet tube. An operation ring is mounted to the collar and connected the engaging. A C-clip is mounted to the outer periphery of the collar. When the operation ring is rotated, the second end of the engaging member is pushed to move within the through hole of the collar to position a socket located in the reception hole of the ratchet tube.
