Abstract:
An inflatable bed includes a bedstead assembly, a mattress assembly having at least one air chamber, and an electric air pump unit disposed on the bedstead assembly. The air pump unit includes a centrifugal pump device for performing initial inflation of the air chamber, a diaphragm pump device for performing subsequent inflation of the air chamber, and a control valve operable to allow for and interrupt fluid communication between the centrifugal pump device and the air chamber.
Abstract:
An envelope is made by at least heat sealing two face sheets. Each face sheet has thick marginal parts and spaced apart thick connection parts. The envelope has at least one heat-sealed peripheral joint, and a plurality of spaced apart heat-sealed seams. The heat-sealed seams are provided on the thick connection parts, and the heat-sealed peripheral joint is provided on the thick marginal parts. The thick connection parts have spaced apart longitudinal strips, and at least one transverse strip extending transversely of the longitudinal strips and interconnecting at least two of the longitudinal strips.
Abstract:
An inflatable product includes an inflatable body with a recess. A pump matching the recess is installed in the recess. Whereby, the inflatable body and pump are integrated together, and it is very convenient to use and carry. Furthermore, the pump is concealed in the inflatable product, giving the inflatable product an attractive appearance.
Abstract:
An inflatable product includes an inflatable body, a fan and motor assembly for pumping air, a housing built into the inflatable body, and an air conduit disposed at least in part in the housing. The housing has an interior region. The air conduit is movable between a first position and a second position, the fan and motor inflating the inflatable body when the air conduit is in the first position, and deflating the inflatable body when the air conduit is in the second position. Air flows between the interior region of the housing and the inflatable body during inflation and deflation.
Abstract:
An inflatable product includes a first chamber, a first mechanically-controlled valve, an air pump, a first switch and a switch circuit. The air pump inflates the first chamber through the first mechanically-controlled valve. The first switch activates the air pump and opens the first mechanically-controlled valve. The air pump is activated through the switch circuit by the first switch, wherein the switch circuit has a second switch turned on by the first switch when the first switch is turned on, and a relay activated to supply the air pump with power when the second switch is turned on.
Abstract:
A water jet massage apparatus includes a body for supporting a user's body. A chamber is defined in the body and through a top surface of the body. An elastic water-proof film formed on the top surface of the body to cover the chamber. A water spraying member installed in the chamber and directly jetting water towards the elastic water-proof film. Whereby, while a user lies or sits on the body, water is jetted by the water spraying member to the elastic water-proof film to massage the user's body. The user can use his massage apparatus without taking off. Moreover, this massage apparatus can be conveniently used at anywhere.
Abstract:
An inflating/deflating device in combination with an inflatable mattress having multiple chambers includes a casing with an inlet and three outlets, a pump received in the inlet to provide inflation/deflation to the chambers of the inflatable mattress and multiple controllable valves respectively and movably mounted on the outlets such that the pump is able to inflate/deflate the chambers of the inflatable mattress simultaneously.
Abstract:
A swirling bathing tub includes a bathing tub, a water ejecting device mounted on an inner side face of the bathing tub and having at least one water outlet defined in the casing and a water inlet for connection with a water source, a water pump mounted inside the casing and having a water inflow pipe in communication with the water inlet and a water outflow pipe corresponding to the at least one water outlet, a baffle rotatably mounted inside the casing and having at least one through hole corresponding to the at least one water outlet so that water flowing through the water outflow pipe of the pump is able to selectively flow to the bathing tub to create a soothing massaging effect to the user.
Abstract:
A self inflatable mattress includes a main portion with a first chamber and a sponge in the first chamber, an extended portion and having a second chamber, a valve mounted on the main portion to allow surrounding air to enter the first chamber and a unidirectional valve received in the extended portion and sandwiched between the first chamber and the second chamber to provide alternate communication between the first chamber and the second chamber. A self expansion of the main portion due to the automatic expansion of the sponge from a compressed state to a non-compressed state allows the surrounding air to enter the first chamber, the air inside the first chamber is able to be forced to enter the second chamber by pushing away the unidirectional valve to resume communication between the first chamber and the second chamber so that the second chamber is inflated.
Abstract:
A plastic product is fabricated from plastic sheets by heat sealing the plastic sheets to form an enclosure member. In order to strengthen the heat-sealed joints of the plastic sheets, the plastic sheets are thickened at portions where the heat-sealed joints are to be formed. Preferably, the heat-sealed joints are formed in such a manner that the cross-section of the heat-sealed joints is smaller than that of the thickened portions of the plastic sheet, thereby preventing effectively the non-thickened portions of the plastic sheets from being affected adversely by the heat sealing process.
