When the movable motor works, the upper end and the lower end of the movable motor can be provided with the baffle plates parallel to the transverse rack or the longitudinal rack, so that the movable motor is prevented from rotating, and the movable motor is ensured to move along the transverse direction or the longitudinal direction when working. By controlling the operation of the movable motor, the transverse rod and the longitudinal rod move to drive the motor mounting seat to move, so that the motor part and the pump body part move. The transverse rod or the longitudinal rod can be respectively provided with a moving motor, a moving gear and a corresponding transverse rack or a corresponding longitudinal rack at two ends, and the moving motor synchronously rotates to prevent the transverse rod or the longitudinal rod from being blocked.

The bottom in the water tank is fixedly connected with a water collecting tank 111 at the front end of the bed body; a plurality of guide pipes 1115 are uniformly distributed at the upper end of the water collecting tank; each guide pipe is communicated with the water collecting tank; a piston column 6 is connected in each guide pipe in a sliding manner; a water inlet pipe 1111 for feeding water into the water collection tank is fixedly connected to one side of the water collection tank; the end part of the water inlet pipe is fixedly connected with a vertical pipe 1113; a check valve 1112 is arranged on the water inlet pipe; the one-way valve is communicated to the water collecting tank from the vertical pipe in a one-way mode; a water inlet connecting pipe 1114 is formed at the upper part of the stand pipe towards the rear end of the bed body; the water inlet connecting pipe is rotatably connected with a rotating connecting pipe 4; the rotary connection pipe includes a guide pipe 41; one end of the guide pipe is in sealed rotary connection with the water inlet connecting pipe; a rotating plate 42 is fixedly connected below one end of the guide pipe positioned at the water inlet connecting pipe; the other end of the guide pipe is sleeved at the outlet of the water spray pipe after rotating; a spring piece 43 is arranged between the rotating plate and the vertical pipe; two ends of the spring piece are respectively fixedly connected with the rotating plate and the vertical pipe; the outlet of the water spray pipe is conical. The rotating connecting pipe enables the guide pipe to be sleeved at the outlet of the water spraying pipe after being rotated.

A water outlet pipe 1116 for discharging water in the water collection tank is formed at one end of the water collection tank away from the rotary connecting pipe; a reset handle 1117 for controlling the opening and closing of the water outlet pipe is arranged on the water outlet pipe; the structure of the reset handle is the same as that of a wrench type water faucet, namely when the reset handle rotates from an initial state, the inside of the water outlet pipe is communicated with the water tank, and when the pressure in the water collecting tank is higher than that in the water tank, water in the water collecting tank enters the water tank through the water outlet pipe; a torsion spring is arranged between the reset handle and the water outlet pipe; after the external force acting on the reset handle is cancelled, the reset handle rotates back to the initial state, and the interior of the water outlet pipe is not communicated with the water tank.

A vertical plate 3122 is fixedly connected to one side of the shell of the pump body part facing the vertical pipe; a transverse pushing column head 3111 for pushing the reset handle is fixedly connected to the housing corresponding to the reset handle. 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 spray pipe after rotating, so that when the driving motor works, water in the water tank is pumped into the guide pipe from the spray pipe through the pump body part and enters the water collection tank, the water pressure in the water collection 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 spray pipe; when the pump body part moves to one side of the water outlet pipe, the reset handle is pushed by the transverse pushing column head 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.

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 use, the pump body part is controlled to move to be close to the vertical pipe through the controller, and the water pump is controlled to work to enable the piston column to ascend; 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.

When the water spray pipe sprays water, the water pump moves through the work of the moving motor, and then a massage effect of pushing is generated.

Example 2

This example is modified from example 1 as follows: a ratchet wheel 24 is fixedly connected to the upper part of the output shaft of the driving motor below the moving seat; a cylindrical cam 25 is sleeved on the ratchet wheel; the inner wall of the cylindrical cam is formed with a ratchet 251 which is in transmission connection with the ratchet; the periphery of the cylindrical cam is formed with W-shaped grooves 252 which are connected end to end along the circumferential direction. When the driving motor rotates forwards to drive the impeller to rotate, idle rotation is formed between the ratchet wheel and the cylindrical cam, namely the cylindrical cam does not rotate along with the ratchet wheel; when the driving motor rotates reversely, the cylindrical cam is driven to rotate through the ratchet wheel.

A transposition sleeve 26 is sleeved on the cylindrical cam; a guide post 262 which is connected in the groove in a sliding way is arranged in the transposition sleeve; the lower end of the transposition sleeve is rotatably connected with a transposition gear 27; a noncircular sliding hole 271 is formed in the center of the transposition gear; a sliding column 212 with the same section as the sliding hole is formed at the lower part of the output shaft of the driving motor corresponding to the transposition gear. The driving motor drives the transposition gear to rotate when working through the matching between the sliding column and the sliding hole.

A fixed seat 211 fixedly connected with the driving motor is arranged below the movable seat; the upper end of the fixed seat is provided with a ring gear 281 and a fixed gear 282 which are meshed with each other; the ring gear is coaxial with an output shaft of the driving motor; an inner ring gear 2811 in meshing transmission connection with the transposition gear is formed in the inner ring of the ring gear.

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; the support ring is provided with a guide bar 21111 corresponding to the guide groove. 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, and when the transposition sleeve moves to the lower end, the transposition gear is meshed with the inner gear ring; when the transposition sleeve moves to the upper end, the transposition gear is separated from the inner gear ring; the rotation angle of the cylindrical cam is controlled by the reverse rotation angle of the driving motor, and the rotation angle is the angle formed by the rotation shaft when the groove goes upwards or downwards, 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.

The engagement or the disengagement 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, and no driving part is additionally arranged for realizing the function.
