[0037] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a medical atomization device 10 provided in an embodiment of the present application can be applied to the medical field or other fields. The medical atomization device 10 includes a housing 100, a bottle body 200, a main body mechanism 300, an atomization mechanism 400, a liquid pumping mechanism 500, a liquid storage mechanism 600 and a control valve 700. The main body mechanism 300 is connected to the housing 100, and the bottle body 200, the liquid pumping mechanism 500, the liquid storage mechanism 600, the atomization mechanism 400 and the control valve 700 can be disposed on the main body mechanism 300.
[0038] Referring to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the housing 100 may include a first housing 110 and a second housing 120, and the first housing 110 and the second housing 120 are detachably connected. For example, the first housing 110 and the second housing 120 can be detachably connected by means of snap connection. By the detachable connection of the first housing 110 and the second housing 120, the convenience of the medical atomization device 10 during the assembly process can be improved, thereby improving the assembly efficiency. An avoidance notch 111 is formed on the first housing 110, and the avoidance notch 111 communicates with the outside and the inner cavity of the housing 100. A part of the liquid pumping mechanism 500 can be received in the avoidance notch 111, so that a part of the liquid pumping mechanism 500 can be exposed through the avoidance notch 111, so that the user can directly contact and operate the liquid pumping mechanism 500 through the avoidance notch 111.
[0039] Referring to Figure 4 and Figure 5 , in some embodiments, the bottle body 200 is connected to the main body mechanism 300, and the bottle body 200 is provided with a liquid storage cavity 210 for storing liquid. The medical atomization device 10 may further include a straw 800. One end of the straw 800 is a fixed end and is fixedly connected to the main body mechanism 300, and the other end of the straw 800 is a free end and extends into the liquid storage cavity 210. The free end of the straw 800 is disposed close to the bottom of the bottle body 200, so that the distance between the free end of the straw 800 and the bottom of the bottle body 200 can be reduced.
[0040] Refer to Figure 4 、 Figure 8 、 Figure 9 and Figure 10 ,In some embodiments, the main body mechanism 300 includes a substrate 350, a first mounting tube 310, a second mounting tube 320, a third mounting tube 330, and a fourth mounting tube 340. The first mounting tube 310, the second mounting tube 320, the third mounting tube 330, and the fourth mounting tube 340 are all protrudingly disposed on the substrate 350. The first mounting tube 310 and the substrate 350 enclose a first lumen 311, the second mounting tube 320 and the substrate 350 enclose a second lumen 321, the third mounting tube 330 and the substrate 350 enclose a third lumen 331, and the fourth mounting tube 340 and the substrate 350 enclose a fourth lumen 341. The second lumen 321 and the third lumen 331 are always in communication with each other. Liquid is allowed to flow unidirectionally from the first lumen 311 into the third lumen 331, that is, liquid cannot flow from the third lumen 331 into the first lumen 311. And liquid is allowed to flow unidirectionally from the fourth lumen 341 into the first lumen 311, that is, liquid cannot flow from the fourth lumen 341 into the first lumen 311. In fact, the fourth lumen 341 will form a liquid guiding cavity 303, and a straw 800 is inserted into the fourth lumen 341. The liquid in the liquid storage cavity 210 can enter the liquid guiding cavity 303 through the straw 800.
[0041] In some embodiments, the third mounting tube 330 has the longest length, that is, the length of the third mounting tube 330 is greater than the lengths of the first mounting tube 310, the second mounting tube 320, and the fourth mounting tube 340. In this way, the third lumen 331 has sufficient length and volume. The first mounting tube 310 and the second mounting tube 320 are both protrudingly disposed on one side in the thickness direction of the substrate 350, and the third mounting tube 330 and the fourth mounting tube 340 are both protrudingly disposed on the other side in the thickness direction of the substrate 350. In this way, the layout of the first mounting tube 310, the second mounting tube 320, the third mounting tube 330, and the fourth mounting tube 340 can be optimized to achieve the compactness of the structure of the main body mechanism 300.
[0042] Refer to Figure 5 and Figure 10, in some embodiments, the main body mechanism 300 further includes a convex post 360. The convex post 360 protrudes from the substrate 350 and is received in the first lumen 311. The number of the convex posts 360 can be several, and the plurality of convex posts 360 are spaced apart from each other. The control valve 700 can be received in the first lumen 311 such that the control valve 700 is carried on the substrate 350, and the convex post 360 can pass through the control valve 700. By the action of the convex post 360, the control valve 700 can be well positioned to prevent the control valve 700 from rotating around the central axis of the first lumen 311 within the first lumen 311, thereby improving the installation accuracy and installation efficiency of the control valve 700.
[0043] Refer to Figure 4 , Figure 8 and Figure 10 , in some embodiments, a first locking hole 322 is formed in the second installation pipe 320. The first locking hole 322 penetrates through the second installation pipe 320 such that the first locking hole 322 communicates with the second lumen 321. The atomization mechanism 400 can be inserted into the second lumen 321, and the atomization mechanism 400 cooperates with the first locking hole 322, thereby realizing a snap connection relationship between the atomization mechanism 400 and the second installation pipe 320.
[0044] Refer to Figure 6 , Figure 7 and Figure 10 , in some embodiments, the main body mechanism 300 may further include a first limiting ring 371 and a second limiting ring 372. Both the first limiting ring 371 and the second limiting ring 372 protrude from the substrate 350, and the first limiting ring 371, the second limiting ring 372, the third installation pipe 330, and the fourth installation pipe 340 are all located on the same side in the thickness direction of the substrate 350. The first limiting ring 371 is disposed around the second installation pipe 320 and the fourth installation pipe 340, the second limiting ring 372 is disposed around the first limiting ring 371, and the first limiting ring 371 and the second limiting ring 372 are spaced apart from each other. The protruding length of the second limiting ring 372 relative to the substrate 350 may be greater than the protruding length of the first limiting ring 371 relative to the substrate 350. A second locking hole 3721 is formed in the second limiting ring 372, and the second locking hole 3721 penetrates through the second limiting ring 372. During the installation of the bottle body 200, the bottle body 200 can be inserted into the space between the first limiting ring 371 and the second limiting ring 372, and the bottle body 200 cooperates with the second locking hole 3721, so that a snap connection relationship between the bottle body 200 and the second limiting ring 372 can be realized.
[0045] Refer to Figure 11 , Figure 12 and Figure 13, in some embodiments, the atomizing mechanism 400 includes a nozzle 410 and a pre-pressure valve 420. The nozzle 410 is provided with a nozzle opening 401. The pre-pressure valve 420 includes a valve seat 421 and a valve core 422. The valve core 422 has an elastic part 4221. The elastic part 4221 abuts against the valve seat 421 and encloses a first chamber 4211b and a second chamber 4211c that are isolated from each other with the valve seat 421. The first chamber 4211b is communicated with the nozzle opening 401. When the pressure in the second chamber 4211c is greater than or equal to a preset value, the elastic part 4221 disengages from the valve seat 421, causing the first chamber 4211b and the second chamber 4211c to communicate with each other.
[0046] Refer to Figure 11 , in some embodiments, the valve seat 421 is provided with a receiving cavity 4211a. The valve core 422 is received in the receiving cavity 4211a. The valve core 422 further includes a mounting part 4223 and a connecting part 4222. The mounting part 4223 is fixedly connected to the valve seat 421, so that the mounting part 4223 can provide a good sealing effect for the receiving cavity 4211a. The connecting part 4222 is connected between the mounting part 4223 and the elastic part 4221. In the natural state, the cross-sectional dimension of the connecting part 4222 is smaller than the cross-sectional dimensions of the mounting part 4223 and the elastic part 4221. The elastic part 4221 can divide the receiving cavity 4211a into a first chamber 4211b and a second chamber 4211c. The valve seat 421 can be inserted into the second lumen 321, and the valve seat 421 is snap-connected to the second mounting pipe 320, so that the second chamber 4211c and the second lumen 321 are always communicated with each other. Obviously, when the pressure in the second chamber 4211c is less than the preset value, under the action of the self-elastic force of the elastic part 4221, the elastic part 4221 will abut against the inner wall surface of the receiving cavity 4211a, so that there is no gap between the elastic part 4221 and the inner wall surface of the receiving cavity 4211a, thus providing a good isolation effect on the first chamber 4211b and the second chamber 4211c to prevent the first chamber 4211b and the second chamber 4211c from communicating with each other. When the pressure in the second chamber 4211c is greater than or equal to the preset value, the elastic part 4221 disengages from the valve seat 421, that is, the elastic part 4221 disengages from the inner wall surface of the receiving cavity 4211a and there is a gap between the elastic part 4221 and the inner wall surface, and the first chamber 4211b and the second chamber 4211c can communicate with each other through this gap.
[0047] Refer to Figure 12 , in some embodiments, the valve core 422 may further include a reinforcing rib 4224. The reinforcing rib 4224 protrudes from the connecting part 4222. Both ends of the reinforcing rib 4224 are respectively connected to the elastic part 4221 and the mounting part 4223. The number of the reinforcing ribs 4224 can be multiple, and the multiple reinforcing ribs 4224 are arranged at intervals along the circumferential direction of the connecting part 4222. By providing the reinforcing rib 4224, the structural strength of the connecting part 4222 and the entire valve core 422 can be reasonably improved.
[0048] Refer to Figure 13 , in some embodiments, the elastic part 4221 encloses an open cavity 4221a. The open cavity 4221a communicates with the first cavity 4211b. From one end of the open cavity 4221a close to the connecting part 4222 to the end far from the connecting part 4222, the diameter of the open cavity 4221a increases. In this way, the whole elastic part 4221 can be roughly in a horn shape. When the pressure in the second cavity 4211c is greater than or equal to a preset value, it can ensure that the elastic part 4221 quickly disengages from the valve seat 421 so that the first cavity 4211b and the second cavity 4211c communicate with each other. When the pressure in the second cavity 4211c is less than the preset value, it can also ensure that the elastic part 4221 quickly abuts against the valve seat 421 under the action of its own elasticity.
[0049] Refer to Figure 13 , in some embodiments, the valve seat 421 includes a seat body 4211, a sleeve 4212 and a limiting post 4213. The seat body 4211 encloses a receiving cavity 4211a. Both the sleeve 4212 and the limiting post 4213 protrude from the seat body 4211. The sleeve 4212 is arranged around the limiting post 4213. The sleeve 4212 is snap-connected to the nozzle 410. The limiting post 4213 is inserted into the nozzle 410. The sleeve 4212 and the limiting post 4213 are arranged at intervals, so that an annular cavity 4212a is formed between the sleeve 4212 and the limiting post 4213. The annular cavity 4212a can communicate with the spray opening 401. A through hole 4211d is formed in the seat body 4211. The through hole 4211d can communicate the annular cavity 4212a and the first cavity 4211b. The liquid in the second cavity 4211c can be sprayed out from the spray opening 401 through the first cavity 4211b, the through hole 4211d and the annular cavity 4212a in sequence.
[0050] Refer to Figure 13 and Figure 14, in some embodiments, the nozzle 410 includes a bottom plate 411, an outer collar 412, and an inner collar 413. The outer collar 412 and the inner collar 413 protrude from the bottom plate 411. The outer collar 412 is disposed around the inner collar 413, and there is a gap between the outer collar 412 and the inner collar 413. The sleeve 4212 of the valve seat 421 can be inserted into the gap between the outer collar 412 and the inner collar 413, so that the outer collar 412 is snap-connected to the sleeve 4212 of the valve seat 421, thereby realizing the snap-connection relationship between the entire valve seat 421 and the nozzle 410. The inner collar 413 and the bottom plate 411 enclose a communication cavity 4131, and the communication cavity 4131 can communicate with the first cavity 4211b through a through hole 4211d. The limiting post 4213 is inserted into the communication cavity 4131, so that the limiting post 4213 is in clearance fit with the communication cavity 4131, that is, there is a gap between the limiting post 4213 and the inner collar 413, and the liquid flowing out from the through hole 4211d can enter the gap between the limiting post 4213 and the inner collar 413.
[0051] Refer to Figure 14 , in some embodiments, the nozzle 410 further includes a first convex block 414. The first convex block 414 protrudes from the side wall surface of the communication cavity 4131. The number of the first convex blocks 414 is multiple, and the multiple first convex blocks 414 are arranged at intervals along the circumferential direction of the inner sleeve 4212. The first convex blocks 414 are disposed around the limiting post 4213 and are in contact with the first convex blocks 414 along the radial direction of the communication cavity 4131. It can be understood that the limiting post 4213 cooperates with the holes formed by the multiple first convex blocks 414. Through the action of the first convex block 414, the contact between the limiting post 4213 and the side wall surface of the communication cavity 4131 can be effectively avoided, ensuring a reasonable distance between the limiting post 4213 and the side wall surface of the communication cavity 4131, and then there is a gap between the limiting post 4213 and the inner collar 413.
[0052] Refer to Figure 14 , in some embodiments, the nozzle 410 further includes a second convex block 415. The second convex block 415 protrudes from the bottom wall surface of the communication cavity 4131. The number of the second convex blocks 415 is multiple, and the multiple second convex blocks 415 are arranged at intervals along the circumferential direction of the inner sleeve 4212. The second convex block 415 abuts against the end of the limiting post 4213. Through the action of the second convex block 415, the contact between the limiting post 4213 and the bottom wall surface of the communication cavity 4131 can be effectively avoided, ensuring a reasonable distance between the limiting post 4213 and the bottom wall surface of the communication cavity 4131, and then there is a gap between the limiting post 4213 and the bottom wall surface of the communication cavity 4131, that is, there is a gap between the limiting post 4213 and the bottom plate 411.
[0053] Refer to Figure 14, in some embodiments, a first counterbore 4111 is formed by recessing the bottom wall surface of the communication cavity 4131, and a second counterbore 4112 is formed by recessing the bottom wall surface of the first counterbore 4111. The diameter of the first counterbore 4111 is larger than that of the second counterbore 4112, so that the first counterbore 4111 and the second counterbore 4112 together form a stepped hole. The second bump 415 is disposed around the first counterbore 4111, and a nozzle 401 is formed at one end of the second counterbore 4112 away from the first counterbore 4111. The second counterbore 4112 is a circular hole, and the number of the second counterbores 4112 is one or more.
[0054] Refer to Figure 11 and Figure 14 , during the working process, the liquid in the first cavity 4211b can enter the gap between the limiting column 4213 and the inner collar 413 through the through hole 4211d, that is, enter the communication cavity 4131. The liquid entering the communication cavity 4131 can then flow into the first counterbore 4111 from the gap between the limiting column 4213 and the substrate 350, and finally the liquid in the first counterbore 4111 flows into the second counterbore 4112 and is ejected from the nozzle 401.
[0055] Refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , in some embodiments, the liquid pumping mechanism 500 includes a liquid pumping assembly 510 and a first elastic member 520. The liquid pumping assembly 510 is slidably connected to the main body mechanism 300 and encloses a liquid pumping cavity 301 with the main body mechanism 300. The first elastic member 520 is pressed between the liquid pumping assembly 510 and the main body mechanism 300. For example, the liquid pumping assembly 510 includes a button 511 and a first piston 512. The button 511 is received in the avoidance notch 111 of the housing 100. The button 511 can be slidably sleeved outside the first installation tube 310. The first elastic member 520 is in a sleeve shape and abuts against the button 511. The first piston 512 is fixedly connected to the button 511, and the first piston 512 is slidably matched with the first tube cavity 311, that is, the first piston 512 and the button 511 can slide relative to the first installation tube 310 synchronously. The first piston 512, the first installation tube 310 and the substrate 350 together enclose the liquid pumping cavity 301, and the first piston 512 seals the liquid pumping cavity 301. Obviously, the liquid pumping cavity 301 is part of the first tube cavity 311. When the first piston 512 moves closer to the control valve 700, the volume of the liquid pumping cavity 301 decreases. When the first piston 512 moves away from the control valve 700, the volume of the liquid pumping cavity 301 increases.
[0056] Refer to Figure 4 , Figure 5 , Figure 6 and Figure 7, in some embodiments, the button 511 has a first conical surface 5111, and the first elastic member 520 is sleeved outside the first conical surface 5111. When the button 511 moves closer to the control valve 700 and the liquid extraction chamber 301 decreases, the part with a larger radius of the first conical surface 5111 will contact the first elastic member 520, causing the first conical surface 5111 to extrude the first elastic member 520 outward, so that the first elastic member 520 generates an outward expansion effect, thereby increasing the cross-sectional size of the first elastic member 520 and also enabling the first elastic member 520 to store energy. Conversely, when the first elastic member 520 releases energy, the cross-sectional size of the first elastic member 520 will decrease, causing the first elastic member 520 to contact the part with a smaller radius on the first conical surface 5111, and then causing the first elastic member 520 to push the button 511 and the first piston 512 to move away from the control valve 700, and the volume of the liquid extraction chamber 301 increases.
[0057] Refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , in some embodiments, the main body mechanism 300 has a second conical surface 380, and the structure of the second conical surface 380 is substantially similar to that of the first conical surface 5111. The first elastic member 520 is sleeved outside the second conical surface 380. When the button 511 moves closer to the control valve 700 and the liquid extraction chamber 301 decreases, the part with a larger radius of the second conical surface 380 will contact the first elastic member 520, causing the second conical surface 380 to extrude the first elastic member 520 outward, so that the first elastic member 520 generates an outward expansion effect, thereby increasing the cross-sectional size of the first elastic member 520 and also enabling the first elastic member 520 to store energy. Conversely, when the first elastic member 520 releases energy, the cross-sectional size of the first elastic member 520 will decrease, causing the first elastic member 520 to contact the part with a smaller radius on the second conical surface 380, and then causing the first elastic member 520 to push the button 511 and the first piston 512 to move away from the control valve 700, and the volume of the liquid extraction chamber 301 increases.
[0058] Refer to Figure 4 , Figure 5 , Figure 6 and Figure 7, in some embodiments, the liquid storage mechanism 600 includes a liquid storage component 610, a fixed seat 630, and a second elastic member 620. The fixed seat 630 is fixedly connected to the main body mechanism 300. The liquid storage component 610 is slidably connected to the main body mechanism 300 and encloses a liquid storage cavity 302 with the main body mechanism 300. The second elastic member 620 is pressed between the liquid storage component 610 and the fixed seat 630. For example, the fixed seat 630 can be disposed near the end of the third installation pipe 330 such that the fixed seat 630 is at least partially received in the third pipe cavity 331, and the second elastic member 620 can be generally in the shape of a sleeve 4212. The liquid storage component 610 includes a mounting seat 611 and a second piston 612. The second piston 612 can be fixedly sleeved outside the mounting seat 611. The second piston 612 is slidably engaged with the third pipe cavity 331, that is, the second piston 612 and the mounting seat 611 can slide relative to the third installation pipe 330 synchronously, and the second elastic member 620 abuts against the mounting seat 611. The second piston 612, the third installation pipe 330, and the substrate 350 jointly enclose the liquid storage cavity 302, and the second piston 612 seals the liquid storage cavity 302. Obviously, the liquid storage cavity 302 is part of the third pipe cavity 331. When the second piston 612 moves closer to the control valve 700, the volume of the liquid storage cavity 302 decreases. When the second piston 612 moves away from the control valve 700, the volume of the liquid storage cavity 302 increases.
[0059] Refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , in some embodiments, a sunk groove 6121 is formed on the second piston 612. The sunk groove 6121 is formed on the surface of the second piston 612 for defining the boundary of the liquid storage cavity 302. The sunk groove 6121 communicates with the liquid storage cavity 302, and the sunk groove 6121 can be in a closed-loop shape. When the liquid enters the liquid storage cavity 302, the liquid can also enter the sunk groove 6121, so that the sunk groove 6121 also plays a certain role in accommodating the liquid.
[0060] Refer to Figure 4 , Figure 5 , Figure 6 and Figure 7, in some embodiments, the mounting seat 611 has a third conical surface 6111, and the second elastic member 620 is sleeved outside the third conical surface 6111. When the mounting seat 611 moves away from the control valve 700 and the liquid storage cavity 302 increases, the part with a larger radius of the third conical surface 6111 will contact the second elastic member 620, causing the third conical surface 6111 to extrude the second elastic member 620 outward, so that the second elastic member 620 produces an outward expansion effect, thereby increasing the cross-sectional size of the second elastic member 620 and also enabling the second elastic member 620 to store energy. Conversely, when the second elastic member 620 releases energy, the cross-sectional size of the second elastic member 620 will decrease, causing the second elastic member 620 to contact the part with a smaller radius on the third conical surface 6111, and then causing the second elastic member 620 to push the mounting seat 611 and the second piston 612 to move closer to the control valve 700, and the volume of the liquid extraction cavity 301 decreases.
[0061] Refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , in some embodiments, the fixed seat 630 has a fourth conical surface 631, and the second elastic member 620 is sleeved outside the fourth conical surface 631. When the mounting seat 611 moves away from the control valve 700 and the liquid storage cavity 302 increases, the part with a larger radius of the fourth conical surface 631 will contact the second elastic member 620, causing the fourth conical surface 631 to extrude the second elastic member 620 outward, so that the second elastic member 620 produces an outward expansion effect, thereby increasing the cross-sectional size of the second elastic member 620 and also enabling the second elastic member 620 to store energy. Conversely, when the second elastic member 620 releases energy, the cross-sectional size of the second elastic member 620 will decrease, causing the second elastic member 620 to contact the part with a smaller radius on the fourth conical surface 631, and then causing the second elastic member 620 to push the mounting seat 611 and the second piston 612 to move closer to the control valve 700, and the volume of the liquid extraction cavity 301 decreases.
[0062] In some embodiments, all the components of the entire medical atomization device 10 can be made of plastic materials, so that the material cost of the medical atomization device 10 can be reduced, thereby reducing the manufacturing cost of the medical atomization device 10.
[0063] Refer to Figure 4 , Figure 5 , Figure 6 and Figure 7, in some embodiments, the control valve 700 has a liquid extraction hole 710 and a liquid storage hole 720. The liquid extraction hole 710 is located between the liquid extraction chamber 301 and the liquid guiding chamber 303, and the liquid storage hole 720 is located between the liquid extraction chamber 301 and the liquid storage chamber 302. When the button 511 moves closer to the control valve 700 and reduces the liquid extraction chamber 301, the pressure in the liquid extraction chamber 301 increases, causing the liquid extraction hole 710 to close and the liquid storage hole 720 to open. Therefore, the liquid or gas in the liquid extraction chamber 301 can enter the liquid storage chamber 302 through the liquid storage hole 720, and the liquid or gas in the liquid extraction chamber 301 cannot enter the liquid guiding chamber 303 through the liquid extraction hole 710. When the first elastic member 520 pushes the button 511 to move away from the control valve 700, the pressure in the liquid extraction chamber 301 decreases, causing the liquid extraction hole 710 to open and the liquid storage hole 720 to close. Under the action of the gas pressure in the liquid storage chamber 210, the liquid in the liquid storage chamber 210 can enter the liquid guiding chamber 303 through the straw 800, and then enter the liquid extraction chamber 301 through the liquid extraction hole 710, while the liquid in the liquid storage chamber 302 cannot enter the liquid extraction chamber 301 through the liquid storage hole 720.
[0064] Refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , the working principle of the medical atomization device 10 is introduced as follows:
[0065] First step, in the initial state, there may be no liquid in both the liquid extraction chamber 301 and the liquid storage chamber 302. By applying a pressing force to the button 511 and the first piston 512, the first piston 512 moves closer to the control valve 700 against the elastic force of the first elastic member 520, and then the liquid extraction chamber 301 is reduced. At this time, the liquid extraction hole 710 is closed and the liquid storage hole 720 is open. The gas in the liquid extraction chamber 301 enters the liquid storage chamber 302 through the liquid storage hole 720, and then is discharged from the liquid storage chamber 302 through the second lumen 321, the second chamber 4211c, the first chamber 4211b, the through hole 4211d, the annular chamber 4212a, the communication chamber 4131, the first sink hole 4111, and the nozzle 401 of the second sink hole 4112 in sequence. Figure 6 The dotted arrow in
[0066] represents the flow trajectory of the liquid.
[0067] In the third step, continue to apply a pressing force to the button 511 and the first piston 512, so that the first piston 512 moves closer to the control valve 700 against the elastic force of the first elastic member 520. Subsequently, the liquid suction chamber 301 is reduced. At this time, the liquid suction hole 710 is closed and the liquid storage hole 720 is opened. The gas in the liquid suction chamber 301 enters the liquid storage chamber 302 through the liquid storage hole 720, causing the liquid in the liquid storage chamber 302 to push the second piston 612 and the mounting seat 611 to move closer to the fixed seat 630 against the elastic force of the second elastic member 620, and the volume of the liquid storage chamber 302 increases. Of course, in the case of a large amount of liquid, the liquid in the liquid storage chamber 302 can also enter the second chamber 4211c. Given that the hydraulic pressure formed by the liquid in the liquid storage chamber 302 and the second chamber 4211c is too small to push the elastic portion 4221 of the valve core 422 away from the valve seat 421, that is, the elastic portion 4221 still abuts against the valve seat 421, so that the first chamber 4211b and the second chamber 4211c are isolated from each other, and the liquid in the second chamber 4211c cannot enter the first chamber 4211b.
[0068] In the fourth step, the button 511 can be repeatedly pressed multiple times, which will cause more liquid in the liquid storage chamber 210 to enter the liquid storage chamber 302 through the liquid suction chamber 301. As the amount of liquid in the liquid storage chamber 302 and the second chamber 4211c increases, the liquid pressure formed by the liquid in the liquid storage chamber 302 and the second chamber 4211c gradually increases. When the liquid pressure in the liquid storage chamber 302 and the second chamber 4211c is greater than or equal to the preset value, the elastic portion 4221 of the valve core 422 will be separated from the valve seat 421 under the action of the liquid pressure, so that the first chamber 4211b and the second chamber 4211c are connected to each other. Subsequently, the liquid in the liquid storage chamber 302 is sprayed to the outside through the second chamber 4211c, the first chamber 4211b, the through hole 4211d, the annular chamber 4212a, the communication chamber 4131, the first counterbore 4111 and the nozzle 401 of the second counterbore 4112, thereby realizing the spraying of the liquid by the medical atomizing device 10.
[0069] After the nozzle 401 starts spraying, stop pressing the button 511. At this time, the second elastic member 620 will release energy, and the second elastic member 620 will push the second piston 612 and the mounting seat 611 away from the fixed seat 630, thereby reducing the liquid storage cavity 302, reasonably increasing the pressure of the liquid in the liquid storage cavity 302, and enabling the liquid in the liquid storage cavity 302 to continuously pass through the nozzle 401 for spraying. It can be understood that as the continuous spraying progresses, the liquid volume in the liquid storage cavity 302 and the second cavity 4211c decreases. When the liquid pressure formed by the liquid in the liquid storage cavity 302 and the second cavity 4211c is less than the preset value, the elastic portion 4221 of the valve core 422 will abut against the valve seat 421 under the action of its own elastic force, so that the first cavity 4211b and the second cavity 4211c are isolated from each other, and the liquid in the second cavity 4211c cannot enter the first cavity 4211b and spray out from the nozzle 401. At this time, the medical atomization device 10 will stop spraying.
[0070] If a mode of setting high pressure in the medical atomization device 10 to spray the liquid is adopted, since the gas in the medical atomization device 10 will be higher than the atmospheric pressure, the medical atomization device 10 needs to have a relatively high mechanical strength to withstand the internal high pressure. In this way, the housing 100 of the medical atomization device 10 will be made of a metal material with a relatively high strength, thereby increasing the material cost and manufacturing cost of the medical atomization device 10. Other components such as the button 511 of the medical atomization device 10 can be made of plastic materials. Therefore, some components of the medical atomization device 10 are made of plastic materials, while another part of the components are made of metal materials. During the process of recycling the discarded medical atomization device 10, due to the different materials of the components, it is necessary to sort the metal components and plastic components, thereby increasing the workload of recycling and the recycling cost. At the same time, when the spraying stops, there will be liquid dripping at the nozzle 401.
[0071] For the medical atomization device 10 in the above embodiments, only by pressing the liquid extraction assembly 510 and under the action of the control valve 700 and the liquid storage mechanism 600, the atomization mechanism 400 can continuously spray the liquid. In this way, there is no need to store a certain high pressure in the medical atomization device 10, thereby reducing the requirements for the strength of the housing 100. As a result, the housing 100 and other components of the medical atomization device 10 can all be made of plastic materials, thus reducing the material cost and manufacturing cost of the medical atomization device 10. Given that all components of the medical atomization device 10 can be made of plastic materials, during the process of recycling the discarded medical atomization device 10, there is no need to sort the components according to different materials, thereby improving the convenience of recycling and reducing the recycling cost. At the same time, when the pressure in the liquid storage chamber 302 is less than the preset value, the elastic portion 4221 of the valve core 422 will abut against the valve seat 421 under the action of its own elastic force, so that the first chamber 4211b and the second chamber 4211c are isolated from each other, and the liquid in the liquid storage chamber 302 and the second chamber 4211c cannot enter the first chamber 4211b and the spraying stops. Therefore, after the medical atomization device 10 stops spraying, the liquid cannot enter the first chamber 4211b and cause dripping at the spray nozzle 401. Thus, the dripping phenomenon at the spray nozzle 401 after the medical atomization device 10 stops spraying can be eliminated.
[0072] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0073] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
