The invention relates to a through floor protection sleeve. The sleeve comprises two semicircular cylinders which are axially hinged along the outer side of the circumference, semicircular supporting plates arranged in the semicircular cylinders, insulation materials arranged on the supporting plates and locking covers arranged outside the semicircular cylinders in a covering manner; first steps locked on a floor through bolts are arranged on the semicircular cylinders, second steps locked on the floor through bolts are arranged on the locking covers, and plural compressing holes are evenly distributed in the circumferences of the semicircular cylinders; and plural protruding columns corresponding to the compressing holes are arranged on the supporting plates and arranged in the compressing holes in a penetrating manner, and the protruding columns stretch out of one ends of the semicircular cylinders to be in a circular arc shape.

A sheet product dispenser (1) for dispensing a strip (51) of a sheet product from a static center-feed coreless roll of sheet product, said roll (5) comprising a central cavity (52), the dispenser comprising a container for accommodating the roll (5), and a dispensing piece (9) which protrudes toward an interior of the container from one end of the container and which includes a guidance (92) between a receiving opening (94) for receiving the strip (51) of sheet product from said roll (5) and a dispensing opening (93) for dispensing the strip (51) of sheet product outside of the dispenser (1), wherein the dispensing piece (9) is arranged to engage into the central cavity (52) of the roll (5). The dispensers (1) allow providing a dispensing opening so that withdrawal of a sheet product is facilitated by avoiding collapsing or clogging. Furthermore, the dispenser (1) has a compact configuration that allows gaining space during delivery and transportation.

The invention discloses a card blocking prevention device for a hotel door. The card blocking prevention device comprises a door frame and a door body, wherein a sliding way communicating with the outer sidewall of the door body is arranged in the door body; a sliding plate is slidably connected into the sliding way; a first magnetic block is fixed to the outer side end of the sliding plate; a second magnetic block matched with the first magnetic block is embedded in the inner wall of the door frame; the inner side end of the sliding plate is elastically connected with the inner bottom of thesliding way through a first spring; a plurality of first magnetic plates are embedded in the bottom of the sliding plate at equal intervals; a storing groove is formed in the bottom of the door body;a plurality of circular cavities are formed between the storing groove and the sliding way; second magnetic plates matched with the first magnetic plates are arranged in the circular cavities; the plurality of first magnetic plates and the plurality of second magnetic plates are arranged in a staggered mode; and abutting columns extending into the storing groove are fixed to the lower ends of thesecond magnetic plates; and the abutting columns are sleeved with second springs. The card blocking prevention device is reasonable in structure, a gap in the bottom of the door body can be blocked when the door is closed, and thus a card is effectively prevented from being blocked.

The invention discloses an LPI fuel system and a return fuel minimizing method. A return fuel minimizing logic of a fuel pump may include: after the fuel pump may be driven by detecting a key-on (IG ON) of an engine, the pressure difference [Delta]P (=the bombe fuel pressure P[bombe]-the fuel injection pressure P[injector]) may be detected, and then the target pressure [Delta]P[target] may be set to the engine starting pressure P[start] or at least four different engine running pressures P[running] so that the duty can be maintained, increased or decreased by controlling the fuel pump to optimize the flow rate discharged from the pump, considering the difference of the magnitude between the pressure difference [Delta]P and the target pressure [Delta]P[target], by which the return flow rate which may be affected by the engine heat and the air temperature, can be reduced.

The invention is suitable for the technical field of sporting goods, and provides a badminton collecting device. The badminton collecting device comprises a main bracket, a ball sweeping mechanism, aguide plate, a ball-clamping prevention sweeping mechanism, a driving mechanism and a transmission mechanism, wherein the ball sweeping mechanism is arranged at one end of the main bracket; the guideplate is arranged in the main bracket and positioned on one side of the ball sweeping mechanism; the ball-clamping prevention sweeping mechanism is arranged at the bottom end of the main bracket and positioned between the ball sweeping mechanism and the guide plate; the driving mechanism is arranged on the main bracket and is used for driving the ball-clamping prevention sweeping mechanism to rotate; and the transmission mechanism is arranged on the main bracket and connected with the driving mechanism and is used for driving the ball sweeping mechanism to rotate in the direction which is opposite to the ball-clamping prevention sweeping mechanism. According to the badminton collecting device, the ball-clamping prevention sweeping mechanism is arranged at the bottom end of the main bracket, and the rotating direction of the ball-clamping prevention sweeping mechanism is opposite to the rotating direction of the ball sweeping mechanism, namely the ball-clamping prevention sweeping mechanism and the ball sweeping mechanism rotate oppositely, so that badminton is conveniently clamped and brought into the guide plate, the badmintons are further prevented from being inserted into the bottom of the collecting device, and the collecting efficiency is improved at the same time.
