Description

Technical Field

[0001] The utility model relates to an automatic water inlet and outlet conversion device for an independent water storage bottle of a dental comprehensive treatment table. Background Art

[0002] Dental unit waterlines (DUWLs) are an important part of dental chair units (DCUs), providing water source for oral diagnosis and treatment. However, studies have found that they are often seriously polluted, and the main causes of pollution include failure of anti-back-sucking devices, water source pollution, and biofilm colonization in pipes. Bacteria in DUWLs can enter the patient's mouth with the water flow, and can also form aerosols to pollute the clinic environment, causing nosocomial infections in patients and medical staff. This is one of the key infection control measures in the process of oral diagnosis and treatment. In this regard, there are many related intervention and control measures at home and abroad, which are mainly divided into physical measures and chemical measures.

[0003] Among them, physical measures include flushing waterways, emptying waterways, installing filtering devices, anti-back-suction devices, and using sterile water, distilled water, or deionized water. Using sterile water, distilled water, or deionized water as water supply for dental chairs is mainly suitable for dental comprehensive treatment tables with independent water storage tanks. In theory, it can provide better water quality, but in the implementation process, it is very easy to be contaminated due to the back-suction caused by the negative pressure after the high-speed turbine stops, the retention of water flow in the pipe, and the material properties of the pipe. In particular, the temperature and humidity in the water pipe are conducive to the accelerated formation of biofilm. The biofilm in the lumen not only continuously releases microorganisms to pollute the water quality, but is also extremely difficult to remove. Physical measures cannot effectively inhibit the biofilm that has been generated. Therefore, regular monitoring and disinfection and maintenance of DUWLs can ensure that the sanitary quality of oral treatment water meets the relevant standards. Regular chemical disinfection can effectively control the content of microorganisms in the waterway while inhibiting the formation and development of biofilm, and play a good bacterial control effect. The ideal dental waterway microbial control method can not only ensure the effectiveness and sustainability of waterway disinfection, but also save labor costs and time costs.

[0004] According to the latest group regulations, independent water storage bottle dental comprehensive treatment units should effectively disinfect water storage bottles. Conventional disinfection measures have many work links and complicated procedures, and the total manual operation time is 30 minutes, which not only increases the workload of operators, but also increases the possibility of exogenous contamination of water storage bottles due to the need to repeatedly disassemble and assemble water bottles. Utility Model Content

[0005] The utility model provides an automatic water inlet and outlet conversion device for an independent water storage bottle of a dental comprehensive treatment table, through which the independent water bottle can be connected to an external pipeline disinfection device, thereby realizing simultaneous automatic cleaning, disinfection and emptying of the water channel of the comprehensive treatment table and the independent water bottle, providing a more efficient solution for dental water channel microbial control.

[0006] According to one aspect of the embodiment, there is provided an automatic water inlet and outlet conversion device for an independent water storage bottle of a dental comprehensive treatment table, comprising:

[0007] A water valve, which connects a water storage bottle, a water pipe for an instrument tray and a dental chair pipe cleaning machine, wherein water from the dental chair pipe cleaning machine is injected into the water storage bottle through the water valve, and the water in the water storage bottle flows into the water pipe for an instrument tray through the water valve under gas pressure; an air valve, which connects the water storage bottle and an air source, wherein the air valve releases the pressure in the water storage bottle before the water from the dental chair pipe cleaning machine is injected into the water storage bottle, and allows the gas provided by the air source to enter the water storage bottle during the process of the water in the water storage bottle entering the water pipe for an instrument tray; and a control module, which connects the water valve and the air valve and controls the states of the water valve and the air valve.

[0008] In some examples, the water storage bottle is connected to the first port of the water valve through a water pipe, and the second port and the third port of the water valve are connected to the water pipe for the instrument tray and the dental chair pipe cleaning machine, respectively.

[0009] In some examples, when water from the dental chair pipe cleaning machine is injected into the water storage bottle, the first port and the third port are connected, and the first port and the second port are blocked; when the water in the water storage bottle is pressed into the water pipe for the instrument tray, the first port and the third port are blocked, and the first port and the second port are connected.

[0010] In some examples, the portion of the water tube within the water storage bottle is close to the bottom of the water storage bottle.

[0011] In some examples, the air outlet of the air valve is connected to the water storage bottle via an air pipe.

[0012] In some examples, the portion of the air tube within the water bottle is close to the mouth of the water bottle.

[0013] In some examples, a first liquid level sensor for detecting whether the water storage bottle is filled with water is installed on the air pipe.

[0015] Figure 1The utility model is a schematic diagram of an automatic water inlet and outlet conversion device for an independent water storage bottle of a dental comprehensive treatment table according to an embodiment of the utility model.

[0016] Figure 2 It is a schematic diagram of an automatic water inlet and outlet conversion device for an independent water storage bottle of a dental comprehensive treatment table according to another embodiment of the utility model. DETAILED DESCRIPTION

[0017] like Figure 1 The automatic water inlet and outlet conversion device for a water storage bottle includes a water valve 1, an air valve 2 and a control module 3. The water storage bottle 4 is connected to the first port 11 of the water valve 1 through a water pipe 5, and the water pipe 5 is close to the bottom of the water storage bottle 4. The second port 12 and the third port 13 of the water valve 1 are respectively connected to the water pipe 14 for the instrument tray and the dental chair pipeline cleaning machine 15. The air inlet 21 of the air valve 2 is connected to the air source 6 (the air source 6 is used to pressurize the water storage bottle 4), and the air outlet 22 of the air valve 2 is connected to the water storage bottle 4 through the air pipe 7, and the air pipe 7 is close to the bottle mouth of the water storage bottle 5. The exhaust port 23 of the air valve 2 is used to relieve the pressure of the water storage bottle 4. A first liquid level sensor 8 is installed on the air pipe 7. A second liquid level sensor 9 is installed on the water pipe 5. When water is added to the water storage bottle 4, when the water is full to the first liquid level sensor 8, stop adding water. The second liquid level sensor 9 detects whether the water storage bottle is in an empty bottle state.

[0018] The present invention does not limit the types of the water valve 1 and the gas valve 2. Figure 2 As shown, the water valve 1 and the gas valve 2 are respectively an air-controlled water conversion valve and an air-controlled gas conversion valve, that is, the actuators of the water valve 1 and the gas valve 2 are pneumatic, and the required gas source and the gas source 6 for pressurizing the water storage bottle 4 can be shared. An air-controlled water conversion valve driving solenoid valve 10 and an air-controlled gas conversion valve driving solenoid valve 20 for controlling the gas volume are respectively arranged on the control gas circuit 14 of the air-controlled water conversion valve and the control gas circuit 24 of the air-controlled gas conversion valve. The solenoid valves 10 and 20 are connected to the control module 3. The control module 3 controls the gas volume of the control gas circuits 14 and 24 through the solenoid valves 10 and 20 to realize the control of the actions of the air-controlled water conversion valve and the air-controlled gas conversion valve.

[0019] The water supply process is: the control module 3 controls the water valve 1 and the air valve 2, so that the dental chair pipeline cleaning machine 15, the water valve 1 and the water storage bottle 4 are connected in sequence (at this time, the first port 11 and the second port 12 of the water valve 1 are shut off, and the first port 11 and the third port 13 are connected), the air valve 2 and the water storage bottle 4 are connected, and after the air valve 2 removes the pressure in the water storage bottle 4, the water of the dental chair pipeline cleaning machine can be injected into the water storage bottle 4. During the process of injecting water into the water storage bottle 4, the liquid level sensor 9 senses in real time whether the water in the water storage bottle 4 is full. After the water in the water storage bottle 4 is full, the control module 3 closes the water valve 1 and the air valve 2 to end the water supply.

[0020] The drainage process is: the gas from the air source enters the water storage bottle through the air valve 2 and the air pipe 7 to apply pressure to the water, causing the water to enter the water pipe of the instrument tray from the water pipe 5 and the water valve 1. At this time, the first port 11 and the second port 12 of the water valve 1 are connected, and the first port 11 and the third port 13 are closed.

[0021] The control module 3 of the utility model includes a controller 30 and a timing knob 31. The controller 30 is connected to the water valve 1 (the air-controlled water conversion valve drives the electromagnetic valve 10), the air valve 2 (the air-controlled air conversion valve drives the electromagnetic valve 20), the liquid level sensors 8 and 9, and the timing knob 31. The timing knob 31 is used to set the working time of the device. Within this set time, the device can repeatedly perform the water supply and drainage processes.

[0022] Continue to refer Figure 2 The external signal is the signal of the foot switch of the dental scaler. The dental scaler includes a main unit, a dental scaler handle and a foot switch, which is common knowledge in the art. The controller detects the signal of the foot switch, controls the water valve 1 and the air valve 2 to operate, and executes the water supply and drainage process.

[0023] Because of its integrated pipeline design, the external integrated pipeline cleaning machine can complete the disinfection and flushing process according to the set program without disassembling the water storage bottle, only through the valve in the independent water bottle automatic conversion device. The manual operation of a single water channel disinfection only takes 2 minutes, which greatly improves the convenience of manual operation and reduces the risk of exogenous contamination of the water storage bottle. At the same time, it improves the compliance of manual operation and the sustainability of the disinfection effect of DUWLs. The program involved in the utility model is a simple program that can be easily implemented by those skilled in the art.
