Description

Technical Field

[0001] This utility model relates to the field of oral medical equipment technology, specifically to a water circuit integrated modular structure for a sandblasting dental cleaning machine. Background Technology

[0002] Air polishing scalers are key devices in the field of dental healthcare for teeth cleaning. Their water system plays a crucial role in providing cleaning water, heating water, and precisely controlling the flow of water to achieve the cleaning function. In existing technologies, the water system of air polishing scalers mostly adopts a decentralized layout, where functional components such as inlet pipes, heaters, solenoid valves, and temperature sensors are set up independently and connected one by one through external flexible hoses or rigid pipes to form a complete water circuit.

[0003] In actual production and application, this decentralized layout requires individual pipe connections and structural fixation for each component. This not only makes the assembly process cumbersome and time-consuming, increasing manufacturing costs, but also increases the internal space occupancy due to the numerous and dispersed pipes, limiting the miniaturization and portability of the equipment. Furthermore, the large number of external pipe interfaces, and the potential for leakage due to the poor sealing reliability of each interface, reduces the overall reliability of the water system and the lifespan of the equipment. In addition, when the equipment needs maintenance or component replacement, the dispersed components require disassembly of multiple connection points and fixing structures, making the operation complex and significantly impacting maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings of the existing technology by providing a modular water circuit structure for a sandblasting dental cleaning machine. This structure has the advantages of being compact, having high space utilization, high assembly efficiency, low risk of leakage, and convenient maintenance.

[0005] The technical solution to achieve the purpose of this utility model is: A modular water circuit structure for a dental air blasting machine includes: The module body has an integrally molded or integrated encapsulated water flow channel inside; The heater is integrated and installed on the module body, and forms a heat exchange relationship with the water flow channel; The water inlet and water outlet are located on the outside of the module body and are connected to the water flow channel. The water outlet control valve assembly is integrated and installed on the module body. Its valve chamber is connected to the water flow channel and is used to control the opening and closing or flow direction of the water outlet interface.

[0006] Furthermore, the water inlet interface includes a first water inlet interface and a second water inlet interface. The first water inlet interface is directly connected to the water inlet end of the heater through a water flow channel. The second water inlet interface is connected to a first solenoid valve through a water flow channel. The water outlet end of the first solenoid valve is connected to the water inlet end of the heater through a water flow channel.

[0007] Furthermore, the water outlet includes a first water outlet and a second water outlet.

[0008] Furthermore, the water outlet control valve assembly includes two independent two-position two-way solenoid valves, namely a second solenoid valve and a third solenoid valve; the water outlet of the heater is connected to the water inlet of the second solenoid valve and the third solenoid valve respectively through a water flow channel; the water outlet of the second solenoid valve is connected to the first water outlet port through a water flow channel; and the water outlet of the third solenoid valve is connected to the second water outlet port through a water flow channel.

[0009] Furthermore, the water outlet control valve assembly includes a two-position three-way solenoid valve. The inlet of the two-position three-way solenoid valve is connected to the water outlet of the heater through a water flow channel, and its two outlets are respectively connected to the first water outlet interface and the second water outlet interface through water flow channels.

[0010] Furthermore, the water circuit integrated modular structure also includes a temperature sensing unit, whose temperature sensing part is disposed in the water flow channel within the module body for detecting water temperature.

[0011] Furthermore, the temperature sensing unit includes a first temperature sensor for detecting the inlet water temperature of the heater and a second temperature sensor for detecting the outlet water temperature of the heater.

[0012] Furthermore, the heater is a tubular heater, with its heating tube nested in a spiral or serpentine water flow channel within the module body; or, the heater is a strip, plate, or sheet heating element that exchanges heat with the water flow channel within the module body through heat conduction.

[0013] Furthermore, the module body also integrates a temperature control switch that is electrically connected to the heater.

[0014] The water circuit integrated modular structure of the air-blasting dental cleaning machine provided by this utility model has the following advantages compared with the prior art: 1. Significantly improved assembly efficiency: The modular integrated design integrates multiple functional components into a single module body. The internal integrated water flow channel reduces a large number of external pipeline connection processes, simplifying the water system assembly process, greatly shortening the assembly time, and reducing production and manufacturing costs.

[0015] 2. Effectively reduced risk of leakage: By replacing the traditional multi-section external pipes with an integrated water flow channel, the number of pipe interfaces is significantly reduced, which structurally reduces the probability of leakage caused by interface sealing failure and greatly improves the reliability of the water system.

[0016] 3. Significantly improved space utilization: The integrated layout makes the water system structure extremely compact, significantly reducing the space occupied inside the air-blasting dental scaler, making it possible to miniaturize and port the air-blasting dental scaler, and expanding the application of the equipment in portable clinics, home care and other scenarios.

[0017] 4. Significantly improved maintenance convenience: The modular structure allows major functional components (such as solenoid valves and temperature sensors) to be installed independently on the module body. During maintenance, specific components can be disassembled and replaced according to the fault situation without disassembling the entire water system, which greatly improves maintenance efficiency and reduces maintenance costs.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this is not intended to limit the present invention. Example

[0020] like Figures 1 to 2 As shown in the figure, the water circuit integrated modular structure of the air-blasting dental cleaning machine provided in this embodiment is based on a module body 1, which has all the necessary water flow channels pre-installed inside.

[0021] The following settings are integrated on module body 1: There are two water inlet ports: a first water inlet port 12 and a second water inlet port 4. The first water inlet port 12 is directly connected to the water inlet of the heater 2 through an internal channel. The second water inlet port 4 is connected to the water inlet of the first solenoid valve 3 through an internal channel, and the water outlet of the first solenoid valve 3 is connected to the water inlet of the heater 2 through an internal channel. The first solenoid valve 3 is used to control the opening and closing of the water path through the second water inlet port 4.

[0022] A heater 2: In this embodiment, the heater 2 is a tubular electric heating element, whose heating tube is embedded in the module body 1 and processed into a spiral heating channel to achieve efficient heat exchange. It can be understood that the heater can also be a strip, plate, or sheet heating element, which conducts heat by adhering to the wall of the channel.

[0023] Temperature sensing unit: includes a first temperature sensor 5 and a second temperature sensor 6. The temperature sensing element of the first temperature sensor 5 is disposed in the water flow channel near the water inlet of the heater 2, and is used to monitor the inlet water temperature. The temperature sensing element of the second temperature sensor 6 is disposed in the water flow channel near the water outlet of the heater 2, and is used to monitor the outlet water temperature after heating.

[0024] A temperature control switch 11 is integrated on the module body 1 and electrically connected to the heater 2 and the second temperature sensor 6. It is used to control the start and stop of the heater 2 according to the feedback signal of the second temperature sensor 6 to prevent overheating.

[0025] Two water outlets: a first water outlet 7 and a second water outlet 8. The water outlet of heater 2 is connected to the water outlet control valve assembly via an internal main water outlet channel. In this embodiment, the water outlet control valve assembly includes two independent two-position two-way solenoid valves, namely a second solenoid valve 10 and a third solenoid valve 9. The main water outlet channel is connected to the inlet ends of the second solenoid valve 10 and the third solenoid valve 9, respectively. The water outlet of the second solenoid valve 10 is connected to the first water outlet 7 via an internal channel. The water outlet of the third solenoid valve 9 is connected to the second water outlet 8 via an internal channel. The second solenoid valve 10 and the third solenoid valve 9 independently control the on / off state of the two water outlet paths.

[0026] As an alternative to this embodiment, the water outlet control valve group can be a two-position three-way solenoid valve, with its inlet connected to the main water outlet channel and its two outlets connected to the first water outlet port 7 and the second water outlet port 8 respectively. The water outlet path can be selected by switching the valve core.

[0027] The work process is as follows: An external water source (such as an internal water tank or external purified water) can be connected to the first water inlet 12 or the second water inlet 4. Water from the first water inlet 12 flows directly into the heater 2. Water from the second water inlet 4 is controlled by the first solenoid valve 3. The water input from the first water inlet 12 or the second water inlet 4 is heated in the flow channel of the heater 2. The second temperature sensor 6 monitors the heated water temperature in real time, and the data is fed back to the temperature control switch 11 controlled by the temperature control system to achieve precise temperature control. The heated constant-temperature water flows to the water outlet control valve group through the main water outlet channel. By controlling the action of the valve group, single-channel water outlet (e.g., the first water outlet 7 is connected to the ultrasonic handpiece, and the second water outlet 8 is connected to the sandblasting handpiece) or dual-channel water outlet control can be achieved to meet different treatment needs.
