The periphery of the shell is also provided with a second spray pipe 313 which is centrosymmetric with the first spray pipe by the axis of the shell; a side retainer ring 33 which is coaxial with the impeller is arranged in the shell; a second ratchet wheel 332 is formed at the lower part of the side retainer ring; a second ratchet 322 in transmission connection with the second ratchet is formed at the position of the impeller corresponding to the second ratchet. When the impeller rotates reversely, the impeller drives the side retainer ring to rotate.

Odd side openings 331 are formed in the side retaining rings at equal intervals; the side baffle ring is positioned between two adjacent side openings to form a side baffle 333; the sum of the angles of the side openings corresponding to the axis is 180 degrees, namely the angles of the side openings and the side baffle plates corresponding to the axis are equal; the side guards can block the junction of the first or second sprinkler tubes. The side openings are opposite to the side baffle plates because the number of the side openings is odd; when the connection of the first sprinkler pipe is blocked by the side baffle, the side opening is located at the second sprinkler pipe, that is, the first sprinkler pipe is blocked and the second sprinkler pipe is conducted.

When the pump body part moves to be close to the vertical pipe, the vertical plate is in mutual contact with the rotating plate to compress the spring piece, and the guide pipe is sleeved on the first water spraying pipe after rotating, so that when the driving motor works, water in the water tank is pumped into the guide pipe from the first water spraying pipe through the pump body part and enters the water collecting tank, the water pressure in the water collecting tank is increased, and the piston column moves upwards; when the pump body part moves towards the direction far away from the vertical pipe, the spring piece enables the rotating plate to rotate under the action of elastic potential energy, and the guide pipe is separated from the outlet of the first water spraying pipe; when the pump body part moves to one side of the water outlet pipe, the reset handle is pushed by the end part of the transverse pipe along with the movement of the pump body part towards one side of the reset handle, water in the water collecting tank is discharged through the water outlet pipe, the pressure in the water collecting tank is the same as that in the water tank, and the piston column descends to an initial state due to the reduction of the pressure in the water collecting tank and the action of self gravity.

The upper end of the water tank is fixedly connected with a bed surface 10 covering the water tank; the bed surface is made of latex or silica gel; an operation panel used for users is installed on the bed body. When the piston column moves upwards, the bed is supported to be upwards convex to form a pillow shape for a user to use; since the pressure at each location in the header tank is equal, the piston posts move an equal distance upward.

Further, a pressure sensor is arranged in the water collecting tank; the pressure sensor is electrically connected with the controller.

The position of the water pump is determined by the number of rotation turns of the two moving motors, and the position of the water pump in the transverse direction and the longitudinal direction is determined by the feedback of the moving motors to the controller.

Before the piston cylinder is used, the controller controls the pump body part to move to a position close to the vertical pipe, controls the side check ring to rotate to conduct the first water spray pipe, and controls the water pump to work to enable the piston cylinder to ascend after the guide pipe is sleeved at the outlet of the first water spray pipe; the ascending distance of the piston column is reflected by the pressure in the water collecting tank, the pressure in the water collecting tank can be controlled by the rotating speed of an impeller in the water pump and the water inlet time, so that the piston column ascends to the middle upper part of the piston column stroke, and at the moment, a pillow-shaped bulge is formed on the bed surface.

Then a user lies on the bed body, the head of the user lies on the protrusion supported by the piston column, at the moment, the piston column acted by the head of the user moves downwards under the action of pressure, the pressure in the water collecting tank is increased, the piston column which is not contacted with the head of the user is forced to move upwards, so that the pressure in the water collecting tank is recovered, the shape of the protrusion formed by the upward movement of the piston column is consistent with the head of the user, the state of the pillow is better simulated, and the phenomenon that the piston column is hard due to the increase of the pressure in the water collecting tank when the piston column rises to the top of the stroke is avoided.

An arc-shaped support ring 2111 for supporting the movable seat is formed above the fixed seat; an extension rod 261 horizontally facing the support ring is formed on the periphery of the transposition sleeve; a guide groove 2611 which is vertically arranged is formed at the end part of the extension rod; and guide strips are formed on the support ring corresponding to the guide grooves.

The groove comprises an upper arc-shaped groove 2521 and a lower arc-shaped groove 2522 which are formed along the horizontal direction; the upper arc-shaped groove and the lower arc-shaped groove are respectively positioned at the upper part and the lower part of the cylindrical cam; two ends of the upper arc-shaped groove and the lower arc-shaped groove are respectively connected with two inclined grooves 2523; the arc formed by the upper arc-shaped groove and one inclined groove corresponding to the axis of the cylindrical cam is 180 degrees; the angles corresponding to the upper arc-shaped groove and the lower arc-shaped groove are equal; the angle corresponding to the inclined groove is equal to the angle corresponding to the side opening. The transposition sleeve can only move in the vertical direction due to the limitation of the guide groove and the guide bar, when the cylindrical cam rotates, the guide post drives the transposition sleeve to move up and down under the action of the groove, when the guide post moves into the lower arc-shaped groove, the transposition sleeve moves to the lower end, and the transposition gear is meshed with the inner gear ring; when the guide post moves into the upper arc-shaped groove, the transposition sleeve moves to the upper end, and the transposition gear is separated from the inner gear ring; the rotating angle of the cylindrical cam is controlled by the reverse rotating angle of the driving motor, so that whether the transposition gear is meshed with the inner gear ring or not is indirectly controlled.

An upper mounting column 2821 which is eccentrically arranged with the fixed gear is mounted on the fixed gear; a lower mounting column 222 is arranged at one side of the fixed gear at the lower end of the movable seat; a connecting rod 29 is arranged between the upper mounting column and the lower mounting column. When the transposition gear is meshed with the inner gear ring, the driving motor rotates positively to drive the impeller to rotate and simultaneously drive the transposition gear to rotate, the ring gear drives the fixed gear to rotate, the moving seat swings back and forth under the action of the connecting rod, and the shell swings back and forth along with the moving seat through the moving seat; when the transposition gear is separated from the inner gear ring, the moving seat does not swing; when the pump body part not only sprays water upwards but also swings back and forth, the massage manipulation of kneading is realized.

Because the angle that the chute corresponds equals with the angle that the side opening corresponds, and the side opening with the quantity of side shield is odd number, consequently go up the arc wall with the angle that the arc wall corresponds down is the side opening with the integral multiple of the angle sum that the side shield corresponds, consequently, when driving motor reverses, the water pump has four operating condition: the transposition gear is disengaged from the inner gear ring and the first water spray pipe is conducted, the transposition gear is disengaged from the inner gear ring and the second water spray pipe is conducted, the transposition gear is engaged with the inner gear ring and the first water spray pipe is conducted, the transposition gear is engaged with the inner gear ring and the second water spray pipe is conducted; and the transition states corresponding to the two chutes.

The four working states can respectively correspond to four manipulation methods, namely the effects of pushing, beating, kneading and swinging.

The engagement or the separation of the transposition gear and the ring gear is controlled through the reverse rotation of the driving motor, so that whether the pump body swings or not is controlled, the function is realized, no driving part is additionally arranged, and the massage effect is increased from two massage effects to four massage effects.
