The rolling assembly 15 is rotatably arranged on the mounting frame, and the rolling assembly 15 can roll and press the ointment squeezed out of the medicine outlet head 13 on the patient's skin. The transmission assembly 17 is connected with the rolling assembly 15. The driving assembly is movably arranged on the shell 10 along the long side direction of the shell 10 and is connected with the transmission assembly 17, the rolling assembly 15 can drive the driving assembly to reciprocate along the long side direction of the shell 10 through the transmission assembly 17, and the transmission assembly 17 can stop the movement of the driving assembly by adjusting the transmission assembly 17. The medicine pushing assembly is slidably arranged in the medicine storage cavity 102 along the long side direction of the shell 10, and the driving assembly can drive the medicine pushing assembly to intermittently move from the rear end of the medicine storage cavity 102 to the front end of the medicine storage cavity 102 when the driving assembly reciprocates along the long side direction of the shell 10.

[0038] In the above embodiment, the shell 10 is held, the rolling assembly 15 is brought into contact with the skin to be applied with medicine, and then the shell 10 is moved to make the rolling assembly 15 roll along the skin. The rolling assembly 15 rolls to drive the driving assembly to reciprocate along the long side direction of the shell 10 through the transmission assembly 17. When the driving assembly reciprocates, the driving assembly can drive the medicine pushing assembly to intermittently move from the rear end of the medicine storage cavity 102 to the front end of the medicine storage cavity 102. The medicine pushing assembly intermittently moves to intermittently squeeze the ointment in the medicine storage cavity 102. When the ointment is squeezed, the ointment is squeezed out of the medicine outlet head 13 through the connecting pipe 14.

[0057] The specific embodiment of the above-mentioned device for conveniently applying a skin ointment in a quantitative manner is as follows:

[0058] When it is needed to spot the ointment on the skin, first of all, the adjusting screw 177 is manually rotated, the adjusting screw 177 is threadedly connected with the connecting shaft 175, so that the connecting shaft 175 is moved along the first guide slot 1761, when the connecting shaft 175 is moved to the end of the first guide slot 1761 far away from the axis of the first rotating disc 176, the connecting shaft 175 is eccentrically arranged with the first rotating disc 176, at this time, the rotation of the first rotating disc 176 makes the connecting shaft 175 eccentrically rotate around the axis of the first rotating disc 176.

[0059] Then the shell 10 is held to make the rolling sleeve 151 contact with the skin, and then the device is moved along the skin to make the rolling sleeve 151 roll along the skin, the rolling sleeve 151 drives the rolling stick 152 to rotate, the rolling stick 152 drives the second bevel gear 153 to rotate, the second bevel gear 153 drives the first bevel gear 154 to rotate, the first bevel gear 154 drives the first transmission shaft 173 to rotate, the first transmission shaft 173 drives the second transmission shaft 174 to rotate through the meshing of the two groups of third bevel gears 171, the second transmission shaft 174 drives the first rotating disc 176 to rotate, the first rotating disc 176 drives the connecting shaft 175 to eccentrically rotate, the connecting shaft 175 eccentrically rotates through the cooperation between the connecting shaft 175 and the second guide slot 2211 to make the transmission rod 22 reciprocate along the long edge direction of the shell 10, and the first rotating disc 176 rotates one circle, the transmission rod 22 reciprocates once, and the reciprocation of the transmission rod 22 drives the plurality of groups of the pushing blocks 223 to reciprocate, when the transmission rod 22 moves backward to make the plurality of groups of the pushing blocks 223 move backward, the pushing block 223 moves to abut against the clamping block 211, the abutment force makes the pushing block 223 rotate and press the first spring 224, and the clamping block 211 moves and presses the second spring 213, at this time, the movement of the pushing block 223 can be staggered with the clamping block 211, after the pushing block 223 is staggered with the clamping block 211, the reaction force of the first spring 224 and the second spring 213 makes the pushing block 223 and the clamping block 211 reset, and when the plurality of groups of the pushing blocks 223 move forward, the pushing block 223 abuts against the clamping block 211 again, at this time, the pushing block 223 can drive the clamping block 211 to move forward, the clamping block 211 moves forward to drive the guide block 21 to move forward, the guide block 21 moves forward to drive the moving block 20 and the connecting column 19 to drive the piston block 18 to move forward, the piston block 18 moves forward to press the ointment in the storage cavity 102, and when the pushing block 223 drives the clamping block 211 to move forward, the clamping block 211 can cooperate with another group of the pushing blocks 223, therefore, through the multiple reciprocations of the transmission rod 22, the plurality of groups of the pushing blocks 223 can be sequentially cooperated with the clamping block 211, so that the piston block 18 is intermittently moved forward to perform the ointment pressing operation, the amount of the ointment pressing is convenient to control, the ointment in the storage cavity 102 is pressed to drop from the medicine outlet 13 to the rolling sleeve 151, and then the rolling of the rolling sleeve 151 can roll the ointment on the skin, so that the ointment is conveniently and quantitatively spotted on the skin of the patient, and the spotting is convenient.

[0060] After the ointment is finished, the ointment is evenly applied. First, the connecting shaft 175 is moved in reverse by manually rotating the adjusting screw 177 in reverse, and when the connecting shaft 175 moves in reverse and is concentric with the first turntable 176, the first turntable 176 rotates to drive the connecting shaft 175 to rotate in the second guide groove 2211. Therefore, the connecting shaft 175 cannot drive the transmission rod 22 to reciprocate, and the medicine outlet head 13 stops dispensing medicine. At this time, the ointment is evenly applied on the skin by rolling the rolling sleeve 151 again, which avoids cross infection, is convenient to apply, and the elastic contraction of the plurality of third springs 162 facilitates the contact between the rolling sleeve 151 and the skin without damaging the skin, thereby improving the comfort of the user.

[0061] When the ointment in the medicine storage cavity 102 is finished, the connecting pipe 14 and the medicine outlet head 13 are disconnected, and the free end of the connecting pipe 14 is inserted into the ointment in the external medicine tank. Then, the anti-slip plate 212 is moved to drive the guide block 21 to move and press the second spring 213, and the guide block 21 is separated from the block 223. At this time, the anti-slip plate 212 can be moved backward to drive the guide block 21 to move the moving block 20 and the connecting column 19 to drive the piston block 18 to move backward. The backward movement of the piston block 18 generates negative pressure in the medicine storage cavity 102, thereby sucking the ointment into the medicine storage cavity 102 through the connecting pipe 14. After the medicine is sucked, the connecting pipe 14 and the medicine outlet head 13 are connected again, and the device can be used to apply and evenly apply the medicine again. The repeated use is convenient.
