[0017] In the utility model, the motor is started to drive the turntable to rotate through the rotation of the first rotating shaft.

Since the third rotating shaft on the first connecting rod is rotatably connected to one end of the second connecting rod, and the piston installed on the push rod at the other end of the second connecting rod can only slide in the spray rod, which plays a limiting role on the second connecting rod, so that the second connecting rod can only expand and contract in the sleeve coinciding with the axis of the spray rod under the drive of the first connecting rod, which is similar to the common crank connecting rod motion. When the piston moves forward, the space where the anesthetic in the spray rod is located is squeezed, and the pressure in the space opens the first one-way valve, and the anesthetic in the spray rod is sprayed out through the spray pipe. When the piston moves backward, a negative pressure is formed in the space where the anesthetic is located, so that the first one-way valve closes and the second one-way valve opens, and the anesthetic in the medicine bottle is adsorbed into the spray rod through the medicine pipe, which is convenient for the next spray. When the rotation speed of the motor is constant, the distance that the piston pushes in the spray rod can determine the actual amount of anesthetic sprayed. The longer the distance that the piston slides in the spray rod, the more anesthetic is sprayed out of the spray rod each time. By adjusting the disk hole at different positions of the first connecting rod on the turntable, the radius of the circular motion of one end of the first connecting rod is changed, which is equivalent to changing the length of the crank in the crank connecting rod motion, driving the reciprocating stroke of the second connecting rod to change, so as to change the distance that the piston slides in the spray rod, and achieve the adjustment of the amount of anesthetic used for a single spray.

A spray pipe 11 is detachably installed on the joint 10, and a spray head 12 is installed at the end of the spray pipe 11; A rechargeable battery and a motor are installed in the box body 2, the battery is electrically connected to the motor, the first rotating shaft of the motor is perpendicular to the front surface of the box body 2, the first rotating shaft faces the front surface of the box body 2, a turntable 14 is installed on the first rotating shaft, the axis of the turntable 14 coincides with the axis of the first rotating shaft, a plurality of disk holes 21 are provided on the turntable 14, the axis of each disk hole 21 is parallel to the axis of the turntable 14, and the distance from each disk hole 21 to the first rotating shaft is different. The turntable 14 is rotationally connected to the first connecting rod 17 through a second rotating shaft 15, and the axis of the turntable 14 is perpendicular to the length direction of the first connecting rod 17. A first rod hole is provided at one end of the first connecting rod 17, and the second rotating shaft 15 is detachably connected in one of the disk holes 21 and the first rod hole; A third rotating shaft 18 is vertically installed at the other end of the first connecting rod 17, and the axis of the third rotating shaft 18 is perpendicular to the length direction of the first connecting rod 17. A second rod hole is provided at one end of the second connecting rod 19, and the third rotating shaft 18 is rotationally connected in the second rod hole; The other end of the second connecting rod 19 is connected to a push rod 20, a piston is installed at the end of the push rod 20, the piston is slidably connected in the spray rod 9, the piston is not separated from the spray rod 9, and the second connecting rod 19 expands and contracts in the sleeve 13; One end of a medicine tube 8 communicates with the side wall of the spray rod 9, the other end of the medicine tube 8 is connected to a medicine bottle 6, and a second one-way valve is installed on the medicine tube 8, and the opening direction of the second one-way valve is from the medicine bottle 6 towards the spray rod 9.

[0026] In the process of specific implementation of the present utility model, the main structures such as the battery and motor of the device are installed in the box body 2, with a small volume, convenient to carry and use. However, the outer shape of the box body 2 of the device is not limited to a rectangle, and can also be set to a shape similar to a pistol, but the internal structure remains unchanged. The device uses a rechargeable battery to start the motor, which is convenient for the device to be used alone. When starting the motor of the device, the first rotating shaft on the motor drives the turntable 14 to rotate. One end of the first connecting rod 17 rotatably connected to the turntable 14 through the second rotating shaft 15 on the turntable 14 will follow the turntable 14 to make a circular motion. The third rotating shaft 18 at the other end of the first connecting rod 17 is rotatably connected to one end of the second connecting rod 19. A push rod 20 is installed at the other end of the second connecting rod 19, and a piston is fixedly installed at the end of the push rod 20. The piston slides in the fixed spray rod 9. Therefore, the spray rod 9 restricts the movement directions of the push rod 20 and the second connecting rod 19, so that the second connecting rod 19 can only move back and forth in the sliding direction of the piston. Therefore, when one end of the first connecting rod 17 makes a circular motion on the turntable 14, the other end of the first connecting rod 17 follows the second connecting rod 19 to move in the movement direction of the spray rod 9, and the third rotating shaft 18 and the second connecting rod 19 remain rotatably connected, and the principle is similar to the crank connecting rod motion. The distance between the second rotating shaft 15 and the first rotating shaft is equivalent to the crank of the crank connecting rod motion. When the length of the crank is longer, the radius of the circular motion of one end of the first connecting rod 17 is longer, so that the moving stroke of the second connecting rod 19 connected to the first connecting rod 17 is longer, that is, the distance that the piston can move on the spray rod 9 is longer, and the amount of anesthetic ejected from the spray rod 9 is more. Therefore, the amount of anesthetic ejected each time can be adjusted by adjusting the distance between the second rotating shaft 15 and the first rotating shaft. When the rotation speed of the motor remains unchanged, the rotation speed of the turntable 14 remains unchanged, the reciprocating sliding speed of the piston remains unchanged, and the more the amount of anesthetic ejected each time, the more the amount of anesthetic spray produced per unit time. The distance between the second rotating shaft 15 and the first rotating shaft can be adjusted by adjusting the second rotating shaft 15 to be rotatably connected to different disk holes 21 on the turntable 14. When the distance between the disk hole 21 where it is located and the first rotating shaft is the largest, the distance between the second rotating shaft 15 and the first rotating shaft is the largest, and the reciprocating distance of the piston in the spray rod 9 is longer, and the anesthetic spray ejected from the spray rod 9 is larger. In order to facilitate the installation of the second rotating shaft 15 in different disk holes 21, the second rotating shaft 15 is detachably connected to the turntable 14. Therefore, further, a clamping block is provided around one end of the second rotating shaft 15, a limit nut 16 is threadedly connected to the second rotating shaft 15, the clamping block is located on the back of the turntable 14, and the limit nut 16 is located outside the first connecting rod 17, and this outside refers to the side away from the turntable 14. The second rotating shaft 15 is inserted into the first rod hole of the first connecting rod 17, and the second rotating shaft 15 is restricted within the turntable 14 and the first connecting rod 17 by the clamping block and the limit nut 16 and cannot be separated, but the second rotating shaft 15 can rotate in the first rod hole and the disk hole 21.When it is necessary to adjust the distance between the second rotating shaft 15 and the first rotating shaft, loosen the limit nut 16 so that the limit nut 16 is disengaged from the second rotating shaft 15, remove the second rotating shaft 15, insert it into the disk hole 21 to be placed and the first rod hole, and then tighten the limit nut 16 so that the second rotating shaft 15 will not be disengaged from the turntable 14 and the first connecting rod 17 and can rotate inside.

[0027] When it is necessary to use the anesthetic spray, start the motor, and the first rotating shaft rotates, so that the turntable 14, the first connecting rod 17, the second connecting rod 19, the second rotating shaft 15, and the third rotating shaft 18 perform a crank - connecting rod motion, so that the piston on the push rod 20 connected to the second connecting rod 19 slides back and forth on the spray rod 9. When the piston moves forward, that is, moves in the direction of the joint 10 of the spray rod 9, the piston squeezes the space filled with anesthetic in the spray rod 9, the internal pressure increases, the first one - way valve is opened, and the second one - way valve is closed, so that the anesthetic is sprayed from the joint 10 of the spray rod 9 into the spray tube 11, and an anesthetic spray is formed through the nozzle 12 on the spray tube 11, which is convenient for treatment. When the piston moves backward, a negative pressure is formed in the spray rod 9, the first one - way valve is closed, and the second one - way valve is opened, and the anesthetic in the medicine bottle 6 is sucked out from the medicine tube 8 into the spray rod 9, waiting for the next forward movement of the piston. Since the distance of each round - trip of the piston remains unchanged and the amount of anesthetic for each spray is fixed, the amount of anesthetic used can be controlled by controlling the starting time of the motor. When the area to be anesthetized is small and the amount of anesthetic spray required per single time is small, the amount of anesthetic spray generated per single time can be reduced by adjusting the distance between the second rotating shaft 15 and the first rotating shaft, that is, the length of the crank, to avoid waste.

[0028] Further, a length scale line is provided on the second connecting rod 19, and the stroke of the movement sliding in the spray rod 9 can be known.

[0029] Further, a medicine slot 5 is opened on the side surface of the box body 2, a baffle 7 is installed at the notch of the medicine slot 5, the medicine bottle 6 is placed in the medicine slot 5, the height of the baffle 7 is lower than the height of the medicine bottle 6, and the medicine tube 8 extends out of the medicine slot 5 from the notch above the baffle 7 and is communicated with the spray rod 9. When it is necessary to replace the anesthetic in the medicine bottle 6 or to clean and disinfect the medicine bottle 6, the medicine bottle 6 can be conveniently taken out from the medicine slot 5. The baffle 7 can prevent the medicine bottle 6 from falling out of the medicine slot 5, and when it is necessary to take out the medicine bottle 6, just open the baffle 7.

[0030] Further, the medicine bottle 6 includes a bottle cap and a bottle body, the bottle cap and the bottle body are detachably connected, which is convenient to open the bottle cap and add anesthetic into the bottle body. The medicine tube 8 is arranged through the bottle cap, and the pipe orifice of the medicine tube 8 is at the bottom of the bottle body, which is convenient to suck the anesthetic in the bottle body into the spray rod 9.

[0031] Further, a medicine adding hole is formed in the bottle cap, and a sealing cover is arranged on the medicine adding hole. The sealing cover can be opened to add anesthetic into the medicine bottle 6 through the medicine adding hole.

[0032] Further, the spray pipe 11 is a disposable plastic hose, one for each person, reducing the probability of cross-infection.

[0033] Further, the head of the spray pipe 11 is an arc-shaped stainless steel pipe. For the treatment of different parts, the requirements for the spray pipe 11 are different. For the throat part, a hard arc-shaped elbow is needed to better reach the affected area. It is made of stainless steel for convenient disinfection and repeated use.

[0034] Due to the long-term use of the spray rod 9, it also needs to be cleaned and disinfected or replaced. Further, the spray rod 9 is threadedly connected to the sleeve 13, which is convenient for removing the spray rod 9.

[0035] Further, a switch button 4 is arranged on the upper end surface of the box body 2. The switch button 4 is electrically connected to the motor, facilitating the control of the motor start through the switch button 4. Further, a time display 3 is arranged on the upper end surface of the box body 2, facilitating the understanding of the using time of the anesthetic spray.
