DETAILED DESCRIPTION

[0018] Specific embodiment one: please refer to Figures 1-3The utility model provides an automatic pressurized inflatable baby sofa, including the cushion 10, the pair of armrests 11 are fixedly connected to the upper end of the cushion 10, and the backrest 13 is fixedly connected between the pair of armrests 11, the upper end surface of the cushion 10 is fixedly connected with the blocking block 16, the upper end of the blocking block 16 is provided with the filter screen 17, the inside of the blocking block 16 is provided with the mounting plate 25 at the lower end of the filter screen 17, the upper side of the mounting plate 25 is fixedly connected with the electric control assembly 18, the lower end of the mounting plate 25 is fixedly connected with the electric cylinder 19, the output end of the electric cylinder 19 is fixedly connected with the piston plate 21, the four spring closure plates two 22 are arranged around the electric cylinder 19 at the mounting plate 25, the four spring closure plates one 20 are arranged around the electric cylinder 19 at the piston plate 21, the lower end of the cushion 10 is provided with the blocking plug 23, through the setting of the electric cylinder 19, spring closure plates two 22, piston plate 21, spring closure plates one 20, utilize the principle of air pump, realize pressurized inflation in the reciprocating process of electric cylinder 19, improve the inflation efficiency, and the blocking block 16 is arranged in the inside of the blocking block 16, is cooperated with the mounting plate 25 to make the blocking block 16 form the stable support to the baby when prostrating forward, improves the security and the comfort degree, through the setting of filter screen 17, prevent the inside of blocking block 16 from being blocked, improve the service life.

[0019] Please refer to Figure 2 The cushion 10 is provided with the mounting groove 24 corresponding to the blocking plug 23, and the blocking plug 23 is located in the inside of the mounting groove 24. Through the setting of the mounting groove 24, the mounting groove 24 is used to hide the blocking plug 23, so that the stability of the cushion 10 is improved, and the baby cannot touch the blocking plug 23 and cause damage, which is more practical.

[0020] Please refer to Figure 2 The upper ends of the two armrests 11 are fixedly connected with the head encircling barriers 12, and the headrests 15 are fixedly connected between the two head encircling barriers 12. The inside of the cushion 10, the armrest 11, the head encircling barrier 12, the backrest 13 and the headrest 15 are connected. Through the setting of the head encircling barrier 12, protection and support are provided when the baby falls on one side, and the safety of use is improved. Through the setting of the headrest 15, the headrest 15 is used as a fulcrum for the baby to grab backward, and the stability of the baby lying backward is improved, and the comfort degree of use is improved.

[0021] Please refer to Figure 1 The inside of the cushion 10, the two armrests 11, the two head encircling barriers 12 and the two headrests 15 is provided with the inflatable ring 14 to prevent bruising.

[0022] In work, by sending signals to the electric control assembly 18, the electric cylinder 19 is started, the output end of the electric cylinder 19 drives the piston plate 21 to press down, at this time, the space between the mounting plate 25 and the piston plate 21 becomes larger, and the gas pressure in it becomes smaller, at this time, the spring sealing plate two 22 on the upper side slides down to open, and the air on the upper side of the blocking block 16 enters the space between the piston plate 21 and the spring sealing plate two 22, when the air pressure is balanced, the spring on the spring sealing plate two 22 drives the middle valve core to reset, and the sealing of the spring sealing plate two 22 is completed; then the electric cylinder 19 is started again, so that the output end of the electric cylinder 19 is pulled up, the air between the mounting plate 25 and the piston plate 21 presses the spring sealing plate one 20 downward, the valve core of the spring sealing plate one 20 is pressed downward to open, and the air between the mounting plate 25 and the piston plate 21 enters the lower side of the piston plate 21, at this time, the air pushes the valve core part of the spring sealing plate two 22 upward, so that the spring sealing plate two 22 cannot be opened downward, and the air can only enter the lower end of the piston plate 21 through the spring sealing plate one 20; since the filter screen 17 is arranged, the filter screen 17 can filter out dust in the air to prevent the spring sealing plate two 22 and the spring sealing plate one 20 from being blocked.

[0023] Since the baby is relatively active, and the baby's skin is delicate, the head protection fence 12 is arranged to try to raise the sofa part around the baby's brain, so that the baby can always touch the parts of the cushion 10, the head protection fence 12, the backrest 13 and the headrest 15 when shaking the head and the body, and the impact on the baby is reduced.

[0024] The headrest 15 is arranged to further improve the protection capability, and the baby can provide a force point when stretching the hand to grip the back side; the inflatable ring 14 provides a force point for the baby to grip when the baby grips, and further protection is provided; since the baby's balance ability is poor, the baby may fall forward when sitting on the cushion 10, and the blocking block 16 is arranged to provide a force point for the baby when falling forward, and prevent the baby from falling.
