Through the provided connecting frame 28, the entire support mechanism 2 can be connected to the negative pressure machine 1 after being folded and stored, thereby ensuring the stability of the support mechanism 2 after storage, avoiding the support mechanism 2 from unfolding on its own, and ensuring the storage effect.

[0080] The structure of the negative pressure machine 1 in this embodiment is described as follows:

[0081] The negative pressure machine 1 is provided with a storage box 12, and a negative pressure tube 11 is connected to the negative pressure machine 1, a support mechanism 2 is connected to the negative pressure machine 1, a universal wheel 6 is fixedly installed on the lower surface of the negative pressure machine 1, and a touch screen is provided on the negative pressure machine 1.

The side wall of the negative pressure machine 1 is provided with a threaded hole. When performing oral care, the negative pressure machine 1 is pushed, and the negative pressure machine 1 is moved to a suitable place through the universal wheel 6. After connecting the power supply, the function is selected through the touch screen, and then the support mechanism 2 is unfolded, and the negative pressure tube 11 is connected to the support mechanism 2.

[0082] The mask mechanism 4 is connected to the card connector 5 at the end of the negative pressure tube 11 to perform aerosol suction operation; the support mechanism 2 is adjusted, and the support mechanism 2 runs with the negative pressure tube 11 until the mask is close to the patient's mouth, and then the oral care work is started. At the same time, the negative pressure machine 1 works to generate negative pressure. Under the action of negative pressure, the dirt and the like cleaned in the patient's mouth enter the negative pressure tube 11 through the mask, and finally enter the negative pressure machine 1, thereby ensuring that the dirt and the like can be cleaned out in time during the oral cleaning process. In the process of oral care, the negative pressure tube 11 can be adjusted at will with the support mechanism 2, which improves the adjustment flexibility. When the care work is completed, the negative pressure tube 11 is disassembled for storage, and the support mechanism 2 is folded and stored on the side wall of the negative pressure machine 1, and then the mask and other items are cleaned and disinfected and placed in the storage box 12, and then the mobile device is placed in the corresponding location.

[0083] The working principle of the aerosol suction device of the utility model is described as follows:

[0084] 1. When using the support mechanism 2, first remove the connecting frame 28 from the negative pressure machine 1, and then unfold the first flip rod 23 and the second flip rod 24. Rotate the rotating rod 25 so that the angle between it and the second flip rod 24 is between 150 and 180 degrees, and then loosen the tightening bolt.

[0085] Adjust the height of the lifting rod 22 relative to the support rod 21, and tighten the bolts after the height adjustment. Then, insert the negative pressure tube 11 into the clamping frame 27, and the clamping joint 5 is located at the rotating rod 25. Connect the mask at the end of the clamping joint 5, and then start using it.

[0086] During the use of the bracket structure, the first flip rod 23 and the second flip rod 24 can be rotated at any angle. When they are rotated to a specific position, they will not continue to rotate due to the action of the second tightening bolt, thereby ensuring the stability of use after adjustment. At the same time, the rotating rod 25 can rotate on the second flip rod 24, further improving the flexibility of use.

[0087] 2. When the clamping mechanism 3 is in use: through the limiting component 33, it can be connected to one end of the supporting component 32, and can also be plugged and installed on the mask mechanism 4, and the clamping component 31 is convenient for medical staff to flexibly clamp it on the bracket or other medical devices according to needs. At the same time, the clamping component 31 can also install the supporting component 32, thereby improving the stability of the use of the limiting component 33. When the mask mechanism 4 is needed, it can be clamped on the bracket or other medical device through the clamping component 31, and then the negative pressure machine 1 is connected to the air outlet end of the mask mechanism 4, and then the supporting component 32 is bent, so that the position of the mask mechanism 4 can be flexibly adjusted through the limiting component 33, so that the mask mechanism 4 can be close to the patient's face, so that the medical staff can use it flexibly.

[0088] When the dental care personnel are performing oral treatment on the patient, the negative pressure machine 1 is turned on, so that the mask mechanism 4 can conveniently absorb the aerosol generated during the treatment process, thereby preventing the aerosol from spreading.

[0089] When the mask mechanism 4 needs to be disassembled and replaced, just unplug the connection end of the negative pressure machine 1 first, and then slide the mask mechanism 4 outward, so that the mask mechanism 4 can be separated from the limit assembly 33, and then the mask mechanism 4 can be quickly disassembled and replaced. Conversely, the mask mechanism 4 can be quickly installed.

[0090] When the clamping assembly 31 is needed, the clamping frame 311 is engaged with the supporting mechanism 2 or the workbench, and then the locking button 314 on the screw hole 313 is rotated, so that the locking button 314 can drive the clamping plate 315 to move closer to the other side wall of the inner cavity of the clamping frame 311, thereby enabling the clamping frame 311 to clamp and fix the supporting mechanism 2 or the workbench, so that the clamping frame 311 can provide a stable foundation for the supporting assembly 32, and the anti-slip rubber plate 316 can increase the friction between the inner wall of the clamping frame 311 and the object, thereby enabling the clamping frame 311 to clamp the object stably.

[0091] Through the first external threaded column 322 and the second external threaded column 323, the two ends of the shaping hose 321 can be connected to the clamping assembly 31 and the limiting assembly 33 respectively, and then by bending the shaping hose 321, the medical staff can flexibly adjust the position of the limiting assembly 33, thereby facilitating the mask mechanism 4 on the limiting assembly 33 to approach the patient's face, so that the medical staff can flexibly use the mask mechanism 4.

[0092] Through the limit block 21 in the limit assembly 33, the second external threaded column 323 can be installed through the second internal threaded tube 22, thereby ensuring the stability of the connection between the shaping hose 321 and the limit block 21, and providing space for the tenon groove 23, thereby facilitating the insertion and installation of the tenon groove 23 on the top of the mask mechanism 4.

[0093] When the mask mechanism 4 is needed, the positioning plate 41 in the mask mechanism 4 can be inserted into the mortise 23 on the limit block 21 through the tenon 43, so that the transparent breathing mask 42 can be installed. Then, through the shaping hose 321, the medical staff can adjust the position of the transparent breathing mask 42 through the limit component 33, so that the transparent breathing mask 42 can be close to the patient's face. Then, through the airway 45, the negative pressure machine 1 can be externally connected, thereby providing adsorption force to the breathing mask 42, so that the breathing mask 42 can absorb the aerosol generated during the diagnosis and treatment process, thereby preventing the aerosol from diffusing, and improving the convenience of using the breathing mask 42.

[0094] When the mask mechanism 4 needs to be disassembled and replaced, the tenon 43 only needs to be slid outward to separate the tenon 43 from the tenon groove 23 on the limit block 21, thereby making it convenient for medical staff to disassemble and replace the transparent breathing mask 42.

[0095] The bottom end of the spring pin 25 can be flexibly engaged in the arc groove 44 on the tenon 43, thereby limiting the tenon 43, so as to prevent the tenon 43 from automatically sliding out of the tenon groove 23, thereby improving the stability of the mask mechanism 4. By reinforcing the rib ring 46, the stability of the bottom end of the transparent breathing mask 42 can be enhanced, thereby preventing the bottom end of the transparent breathing mask 42 from deformation.

[0096] The support mechanism 2 in this embodiment is detachably connected to the clamping assembly 31, and the clamping assembly 31 can also be clamped on the side panel of the nursing cart, which improves the practicality of the structure of the clamping assembly 31; the clamping method of the clamping assembly 31 and the side panel of the nursing cart is similar to the connection method between the support mechanism 2 and the clamping assembly 31, which will not be repeated here.

[0097] 3. After the support structure is used, the negative pressure tube 11 is removed from the clamping frame 27 for storage, the rotating rod 25 is flipped to overlap with the second flip rod 24, and then the two flip rods are stored so that the entire flip rod fits on the lifting rod 22, and then the connecting bolt 284 at the end of the connecting strip 282 is connected to the threaded hole to fix the entire support mechanism 2. During the fixing process, the connecting strip 282 has a flexible effect, such as a common elastic rope, cowhide belt, etc. The connecting strip 282 in this embodiment is preferably an elastic rope. The connecting strip 282 can be deformed to ensure the accuracy of the connection, and then the entire negative pressure device can be moved and stored.

[0098] In addition, the internal structure of the negative pressure machine in this embodiment and its adsorption principle are prior arts, and the negative pressure machine 1 is provided with a touch screen as a conventional setting, which will not be elaborated here.

[0099] This completes the working process of the aerosol inhalation device of this preferred embodiment.

[0100] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
