Patent number: 11963620Abstract: A flat wiredrawing mattress includes at least a top, bottom and a side piece enclosed between the top and bottom piece, at least a hermetic air chamber is formed between the top, bottom and side pieces, a wiredrawing structure is between the top and bottom piece, and the side piece has a tension connecting piece group for tightening and smoothing. During use, the wiredrawing structure prevents the top and bottom piece swelling and makes the mattress surface flatter, avoiding uneven situation. The elastic pulling force of the wiredrawing structure on the top and bottom piece compress the air in the air chamber. The mattress body is not deformed with stable structure and better firmness. The tension connecting piece tightens the side piece, supports and flattens it, and flattens the mattress surrounding. The overall structure of the mattress is flat, and can be kept flush with the wall during use.Type: GrantFiled: November 26, 2020Date of Patent: April 23, 2024Inventor: Shouguo Long

Patent number: 11793321Abstract: A pump assembly is provided for use with an inflatable product. The inflatable product has a chamber having an air inlet and an air outlet. The pump assembly has a pump unit that is positioned inside the chamber for inflating and deflating the chamber, the pump unit having at least one motor that is operatively coupled to a first blower and a second blower, with the first blower fluidly coupled to the air inlet and the second blower fluidly coupled to the air outlet. The chamber is inflated by intake of air through the air inlet to the first blower and then into the chamber, and the chamber is deflated by drawing air from the chamber to the second blower and then out of the chamber through the air outlet.Type: GrantFiled: January 10, 2022Date of Patent: October 24, 2023Inventors: Vincent W.
