An environment cleaning system for an animal breeding house has an outside environment, a breeding house, an air covering, and a cleaning device. The breeding house is deposited in the outside environment. The air covering is deposited in the outside environment and is mounted around the breeding house. The air covering is used to buffer the air pressure between the outside environment and the breeding house. The cleaning device is deposited in the outside environment, is connected to the air covering and the breeding house, and has an air exchanging unit and at least one filtering unit. The air exchanging unit controls the relative pressure among the outside environment, the air covering, and the breeding house to provide a unidirectional air flowing effect, and the flowing direction of the air is based on the relative pressure between the breeding house and the air covering.

A non-alcohol mouthwash composition without chemical antibacterial medicament is disclosed. The non-alcohol mouthwash composition includes from 0.03% to 1.5% of &#x3b3;-polyglutamic acid (&#x3b3;-PGA) and from 0.5% to 4% of surfactant, all percentages based on the total weight of the mouthwash composition. The non-alcohol mouthwash composition preferably includes from 0.4% to 1.5% by weight, or more preferably from 0.8% to 1.3% by weight, of &#x3b3;-PGA. Containing no chemical antibacterial medicament, the non-alcohol mouthwash composition can effectively inhibit bacterial growth in the oral cavity without irritating the oral mucosa.

A hybrid step motor comprises a stator, a rotor assembly, a magnet and a mandrel. The rotor assembly and the magnet are mounted on the mandrel and are disposed in the stator. The proportion of a stator outer diameter to a stator inner diameter is 1:0.475 to 1:0.6. The proportion of the stator outer diameter to a rotor outer diameter is 1:0.5125 to 1:0.5875. The proportion of a first rotor thickness to a magnet thickness to a second rotor thickness is 0.236:0.09:0.236 optimally. The proportion of the rotor outer diameter to a magnet outer diameter is 0.54:0.45. By such arrangements, the optimal proportion is formed and the output efficiency is improved.

An insulation device for being assembled in a linear motor is primarily made through molding a sheet insulation material into an insulation module with the shape harmonized with the shape of an iron core of a linear motor. Thus, coil wildings can be indirectly wrapped around the iron core with the insulation module positioned intermediately and thereby a linear motor with perfect insulation treatment between the iron and coil windings is achieved.

A tongue-and-groove floorboard is composed of a lower board and an upper board mated with the lower board. The lower board and the upper board each have a plurality of channels and ribs longitudinally formed in pairs, wherein the channels and ribs in the lower board and the upper board are complementary. A plurality of recesses are defined between each lower board and upper board, wherein the recesses in the lower board and the upper board are corresponding and can construct circular passages. Sound insulation material is disposed in the passages in the lower board and the upper board. A plurality of slots is defined therein not parallel to the channels and ribs and being staggered respectively in the lower board and the upper board. A tongue is formed at one side of the lower board and upper board, and a groove is defined at the opposite side of the lower board and upper board.
