Description

A kind of air matting

Technical field

This utility model belongs to the articles for daily use, is specifically related to a kind of air matting.

Background technology

Mattress is requisite article of everyday use in people's daily life, and the hardness of existing mattress is all often fixing, unadjustable; Further, seldom having mattress to heat, the mattress that on market, existing minority can heat also is all adopt electric-heating-wire-heating, and this mode of heating is uneven, also has the risk of spontaneous combustion of leaking electricity.

Utility model content

The purpose of this utility model is: the deficiency existed for prior art, it is provided that a kind of simple in construction, scalable hardness, the air matting on homogeneous heating ground.

For realizing the purpose of this utility model, it is achieved by the following technical solutions:

A kind of air matting, includes inflatable packer, and is connected to the medicated pillow of inflatable packer length direction one end,

Also including water pump, air pump and heater, described water pump, air pump and heater are all disposed within inside medicated pillow; Be provided with gas-charging connection in one end of inflatable packer length direction, described gas-charging connection is connected with air pump by trachea;

It is further installed below water pipe network within described inflatable packer, is provided with 1 water out adapter and 1 water supply connector that are connected with water pipe network in one end of inflatable packer length direction; The water intaking valve of described water pump is connected with water out adapter, and the outlet valve of described water pump is connected with heater, and heater is connected with water supply connector by pipeline;

Described water pump, air pump, heater, electromagnetic valve are electrically connected with the controller respectively;

As preferably: described inflatable packer is spliced to form by multiple rectangle air cushions, described rectangle air cushion is hollow structure, at least two avris at rectangle air cushion is connected with 2 gas-charging connections, and the inner volume of each described rectangle air cushion is connected by gas-charging connection;

As preferably: described water pipe network is divided into symmetrical two parts along inflatable packer length direction, and water pipe network is connected away from the end of water supply connector; It is connected also by multiple tubules between two parts of water pipe network, and the 1/10-1/5 that the internal diameter of tubule is water pipe network internal diameter.

Compared with prior art, the beneficial effects of the utility model are:

1, described air cushion can regulate the hardness of air cushion by air pump, by heater, water is heated, makes hot water flow by water pump; Tubule between two parts of water pipe network is connected, and the 1/10-1/5 that the internal diameter of tubule is water pipe network internal diameter, the liquid sluggish flow near water supply connector or water out adapter can be made, be not result in the liquid from water supply connector is come in and flow out from water out adapter again, it is impossible to make overall flow.

2, the housing of described water pump is applied not only to install stator winding, p-m rotor and two pistons are also installed inside it simultaneously, piston is connected at two pump covers at housing two ends, form two plunger displacement pumps, p-m rotor is between two plunger displacement pumps, gathering sill and guide match and make p-m rotor move back and forth in the axial direction while rotating, drive two plunger displacement pump alternations, this water pump structure is compact, and the pumping for water pump comparing equal volume is in hgher efficiency. P-m rotor is in the sealing space between housing and two pistons, even if such piston produces a small amount of leakage after a long time use, the liquid being sucked is without being leaked to outside the pump housing, and a small amount of leak liquid is present in sealing space and will not the work of water pump be impacted. The big distance t of length of the length ratio stator winding of described p-m rotor, distance t is at least the distance that p-m rotor is axially moveable, the motor that such p-m rotor and stator winding are constituted will not produce the situation of leakage field, and relative normal motor, longer p-m rotor weight is bigger, inertia is relatively big, is beneficial to its smooth rotation. Described shaft bearing by inner ring molding ball grooves and arrange ball and rotating shaft and roll and coordinate, makes rotating shaft be in low Frotteurism in rotation and the process that moves along axis, it is ensured that the efficiency of water pump. Described guide is inserted in housing from housing, so when mounted, in ball shrinkage pool, first fill butter, take up the ball guide to penetrate to housing, it is directed to ball again and is installed in ball shrinkage pool, then connecting plate is adjusted vertical with housing, continue inwardly to promote guide to make its front end insert in gathering sill, rotary connection plate makes it snap in guide positions groove again, meanwhile guiding ball also turns to the state towards gathering sill medial wall, is fixed on housing finally by screw by connecting plate and namely completes to install. So facilitate aliging of guide and gathering sill, accelerate the assembling speed of guide.

3, the pump case of described air pump is applied not only to install external stator winding, p-m rotor and two pistons in also installing inside it simultaneously, piston is connected at two pump covers at pump case two ends, form two air pumps, interior p-m rotor is between two air pumps, matched by direction recess and guide post and make interior p-m rotor move back and forth in the axial direction while rotating, drive two air pump alternations. Specifically, owing to the diameter of described first piston is more than the diameter of the second piston, so within a cycle, first air pump charge volume is more than the second air pump charge volume, therefore the first air pump makes in pump case the air pressure between first piston and the second piston raise, when the second air pump air inlet, the pressure differential of the second piston body both sides is bigger so that the outlet pressure of the second air pump is higher; Two air pumps are equivalent to series connection and use, and make the air pressure that air pump exports higher than the air pump with power. The big distance t of length of the length ratio external stator winding of described interior p-m rotor, distance t is at least the distance that interior p-m rotor is axially moveable, the motor that in so, p-m rotor and external stator winding are constituted will not produce the situation of leakage field, and relative normal motor, longer interior p-m rotor weight is bigger, inertia is relatively big, is beneficial to its smooth rotation. Described rotor bearing by bearing inner race molding steel ball mounting groove and arrange steel ball and armature spindle and roll and coordinate, makes armature spindle be in low Frotteurism in rotation and the process that moves along axis, it is ensured that the efficiency of air pump. Described guide post is inserted in pump case from pump case, so when mounted, in steel ball shrinkage pool, first fill butter, take up the ball guide post to penetrate to pump case, it is directed to steel ball again and is installed in steel ball shrinkage pool, then location-plate is adjusted vertical with pump case, continue inwardly to promote guide post to make its front end insert in direction recess, rotating retaining plate makes it snap in guide post locating slot again, meanwhile guiding steel ball also turns to the state towards direction recess medial wall, is fixed on pump case finally by screw by location-plate and namely completes to install. So facilitate aliging of guide post and direction recess, accelerate the assembling speed of guide post.
