Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a saliva suction system for a dental workbench. Background Technique

[0002] The saliva suction system (also known as a saliva aspirator or suction system) of a dental workbench is an important device in a dental clinic for removing saliva, blood and other liquids from a patient's oral cavity during treatment. Such a system helps to keep the operation area dry, ensuring that doctors or dentists can perform treatment better, and can improve work efficiency and patient comfort.

[0003] The saliva suction system of a dental workbench sucks the excess waste liquid in the oral cavity into a waste liquid bottle for collection through a saliva suction pump during teeth cleaning or dental surgery. There is no effective alarm measure in the existing waste liquid bottle of the saliva suction system of a dental workbench when the waste liquid is excessive, so that the user cannot detect it when the waste liquid in the waste liquid bottle is excessive, resulting in the saliva suction pump still working but unable to suck the oral waste liquid after the waste liquid is excessive. In the long run, it is easy to cause damage to the saliva suction pump and the waste liquid bottle. For this reason, we propose a saliva suction system for a dental workbench. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a saliva suction system for a dental workbench. A waste liquid excess alarm component is installed between the relay and the saliva suction waste liquid bottle. When the liquid level of the waste liquid in the saliva suction waste liquid bottle rises to a certain height, the float of the float switch will rise with the waste liquid, so that the float switch is disconnected, and then the relay is disconnected, and the saliva suction pump is powered off and stops working. When the user finds that the saliva suction pump stops working, check whether the saliva suction waste liquid bottle is full. If it is full, remove the saliva suction waste liquid bottle, pour out the waste liquid, and then the saliva suction system can be used again after reassembly. This waste liquid excess alarm component effectively reminds the user when the waste liquid is excessive, avoiding damage to the saliva suction system caused by excessive waste liquid. An opening and closing component is installed on the saliva suction hanging rack valve, so that when the saliva suction gun is taken out of the saliva suction hanging rack valve, the air path on the saliva suction hanging rack valve is opened, and the pneumatic switch is turned on, so that the saliva suction pump starts to work through the relay. When the saliva suction gun is put back on the saliva suction hanging rack valve, the air path is closed and the pneumatic switch is turned off, so that the saliva suction pump stops working through the relay. This opening and closing component simply and conveniently opens and closes the saliva suction system, reducing the labor intensity of the user and solving the problems in the background.

[0005] To achieve the above object, the present utility model is realized through the following technical solutions: A saliva suction system for a dental workbench, comprising a mounting bracket and a saliva suction waste liquid bottle. A number of saliva suction hanger valves are installed on the mounting bracket. The top side opening of the saliva suction waste liquid bottle is threadedly connected with a waste liquid bottle cap.

[0013] Beneficial effects:

[0014] 1. In this dental workbench saliva suction system, a waste liquid over - alarm component is installed between the relay and the saliva suction waste liquid bottle. When the liquid level of the waste liquid in the saliva suction waste liquid bottle rises to a certain height, the float of the float switch will rise with the waste liquid, causing the float switch to disconnect. Subsequently, the relay disconnects, and the saliva suction pump is powered off and stops working. When the user finds that the saliva suction pump has stopped working, they check whether the saliva suction waste liquid bottle is full. If it is full, the user removes the saliva suction waste liquid bottle, pours out the waste liquid, and can use the saliva suction system again after reassembly.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a saliva suction system for a dental workbench, including a mounting bracket 13 and a saliva suction waste liquid bottle 14. A number of saliva suction hanging valve 2 are installed on the mounting bracket 13. The top side opening of the saliva suction waste liquid bottle 14 is threadedly connected with a waste liquid bottle cap 15. A saliva inlet 16 is penetrated and opened on the waste liquid bottle cap 15. A second saliva suction tube 10 is fixedly communicated with the saliva inlet 16. The other end of the second saliva suction tube 10 is fixedly communicated with a saliva suction pump 12. The input end of the saliva suction pump 12 is fixedly communicated with a first saliva suction tube 1. The end of the first saliva suction tube 1 away from the saliva suction pump 12 is fixedly installed with a saliva suction gun 3. The saliva suction gun 3 is clamped on the saliva suction hanging valve 2. And a relay 8 and a saliva suction adapter 11 are arranged between the saliva suction pump 12 and the saliva suction waste liquid bottle 14. An opening and closing component is installed on the saliva suction hanging valve 2. A waste liquid excess alarm component for preventing the waste liquid in the saliva suction waste liquid bottle 14 from exceeding the limit is installed between the relay 8 and the saliva suction waste liquid bottle 14.

[0023] The saliva suction system for the dental workbench accesses 220V alternating current through the saliva suction adapter 11 and exports 12V direct current. The saliva suction adapter 11 is connected to the relay 8. The saliva suction pump 12 is started through the relay 8 to start the saliva suction work. The input end of the saliva suction pump 12 is connected to the saliva suction gun 3 through the first saliva suction tube 1. The excess waste liquid in the oral cavity is absorbed through the saliva suction gun 3. After the waste liquid is inhaled into the saliva suction pump 12, it is sent into the saliva suction waste liquid bottle 14 through the second saliva suction tube 10 at the output end of the saliva suction pump 12 for collection. The saliva suction gun 3 in the saliva suction system is placed on the saliva suction hanging valve 2. By installing an opening and closing component on the saliva suction hanging valve 2, the saliva suction system can be simply and conveniently opened and closed, reducing the labor intensity of the user. And a waste liquid excess alarm component for preventing the waste liquid in the saliva suction waste liquid bottle 14 from exceeding the limit is installed between the relay 8 and the saliva suction waste liquid bottle 14, so that the saliva suction system effectively reminds the user when the waste liquid exceeds the limit, avoiding damage to the saliva suction system due to excessive waste liquid.

[0024] The opening and closing component includes a pneumatic switch 9. The input end of the pneumatic switch 9 is fixedly communicated with a second air pipe 7. The end of the second air pipe 7 is fixedly communicated with the air outlet end of the saliva suction hanging valve 2. The air inlet end of the saliva suction hanging valve 2 is fixedly communicated with a first air pipe 4. The end of the first air pipe 4 away from the saliva suction hanging valve 2 is fixedly communicated with an eight-way valve 6. An air inlet pipe 5 is fixedly communicated with the eight-way valve 6.

[0025] When the opening and closing component is in use, the eight-way valve 6 accesses a 0.5mpa air source through the air inlet pipe 5 and sends it into the saliva suction hanging valve 2 through the first air pipe 4. The saliva suction hanging valve 2 sends it into the pneumatic switch 9 through the second air pipe 7. When the saliva suction gun 3 is taken out from the saliva suction hanging valve 2, the air path on the saliva suction hanging valve 2 is opened, the pneumatic switch 9 is turned on, and thus the saliva suction pump 12 starts to work through the relay 8. When the saliva suction gun 3 is put back on the saliva suction hanging valve 2, the air path is closed and the pneumatic switch 9 is turned off, and thus the saliva suction pump 12 stops working through the relay 8.

[0026] The waste liquid excess alarm component includes a float switch 18, which is installed on the waste liquid bottle cap 15, and the bottom side of the float switch 18 extends into the inside of the saliva suction waste liquid bottle 14.

[0027] When the waste liquid excess alarm component is in use, when the liquid level of the waste liquid in the saliva suction waste liquid bottle 14 rises to a certain height, the float of the float switch 18 will rise with the waste liquid, so that the float switch 18 is disconnected, and then the relay 8 is disconnected, and the saliva suction pump 12 is powered off and stops working. When the user finds that the saliva suction pump 12 stops working, check whether the saliva suction waste liquid bottle 14 is full. If it is full, remove the saliva suction waste liquid bottle 14, pour out the waste liquid, and the saliva suction system can be used again after reassembly.

[0028] A number of exhaust ports 17 are provided on the waste liquid bottle cap 15, and the gas inhaled by the saliva suction pump 12 is discharged through the exhaust ports 17.

[0029] A number of bolt mounting holes are provided on the mounting bracket 13, and the mounting bracket 13 is fixedly installed through the bolt mounting holes.

[0030] The relay 8 is electrically connected to the saliva suction pump 12, the relay 8 is electrically connected to the saliva suction adapter 11, and the float switch 18 is electrically connected to the relay 8. The power supply is connected through the saliva suction adapter 11 and led to the relay 8, and the relay 8 controls the switch of the saliva suction pump 12. When the float switch 18 is disconnected, the relay 8 is controlled to be disconnected, resulting in the closure of the saliva suction pump 12.

[0031] Working principle: The saliva aspiration system of this dental workbench accesses 220V AC power through the saliva aspiration adapter 11 and outputs 12V DC power. The saliva aspiration adapter 11 is connected to the relay 8, and the saliva aspiration pump 12 is started through the relay 8 to start the saliva aspiration work. The input end of the saliva aspiration pump 12 is connected to the saliva aspiration gun 3 through the first saliva aspiration tube 1. Excess waste liquid in the oral cavity is absorbed through the saliva aspiration gun 3. After the waste liquid is inhaled into the saliva aspiration pump 12, it is sent into the saliva aspiration waste liquid bottle 14 through the second saliva aspiration tube 10 at the output end of the saliva aspiration pump 12 for collection. The saliva aspiration gun 3 in this saliva aspiration system is placed on the saliva aspiration hanging rack valve 2. The eight-way valve 6 accesses a 0.5mpa air source through the air inlet pipe 5 and sends it into the saliva aspiration hanging rack valve 2 through the first air pipe 4. The saliva aspiration hanging rack valve 2 sends it into the pneumatic switch 9 through the second air pipe 7. When the saliva aspiration gun 3 is taken out from the saliva aspiration hanging rack valve 2, the air path on the saliva aspiration hanging rack valve 2 is opened, and the pneumatic switch 9 is turned on, so that the saliva aspiration pump 12 starts to work through the relay 8. When the saliva aspiration gun 3 is put back on the saliva aspiration hanging rack valve 2, the air path is closed and the pneumatic switch 9 is turned off, so that the saliva aspiration pump 12 stops working through the relay 8, thus simply and conveniently opening and closing the saliva aspiration system, reducing the labor intensity of the user. Moreover, when the liquid level of the waste liquid in the saliva aspiration waste liquid bottle 14 rises to a certain height, the float of the float switch 18 will rise with the waste liquid, so that the float switch 18 is turned off, and then the relay 8 is turned off, and the saliva aspiration pump 12 is powered off and stops working. When the user finds that the saliva aspiration pump 12 stops working, check whether the saliva aspiration waste liquid bottle 14 is full. If it is full, remove the saliva aspiration waste liquid bottle 14, pour out the waste liquid, and the saliva aspiration system can be used again after reassembly. Thus, the saliva aspiration system effectively reminds the user when the waste liquid is excessive, avoiding damage to the saliva aspiration system due to excessive waste liquid.
