Detailed Description
The present invention will be described in detail with reference to the drawings and specific embodiments, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
As shown in figure 1, the water channel gas alarm device for the oral cavity comprehensive treatment table can be arranged at any place of a water channel, and the effect of being arranged on the water channel of a water pump is the best through experiments. The device comprises a water inlet 1, an arched window flow passage 2, a water outlet 3 and a semi-permeable membrane air filtering alarm mechanism 4; the semi-permeable membrane air-filtering alarm mechanism 4 is positioned at the arch camber of the arched window flow channel 2, the water outlet 3 is positioned at one end of the bottom of the arched window flow channel 2, and the water inlet 1 is positioned at the other end of the bottom of the arched window flow channel 2; the semi-permeable membrane gas-filtering alarm mechanism 4 comprises a connecting sealing ring 41, a gas-permeable semi-permeable membrane 42, a spherical gas chamber 43, a gas outlet 44 and an alarm 45, wherein the gas-permeable semi-permeable membrane 42 is a thickened GORE-TEX film, the gas-permeable semi-permeable membrane 42 is fixed at the bottom of the spherical gas chamber 43 and is connected with the arched window runner 2 through the connecting sealing ring 41, and the area of the gas-permeable semi-permeable membrane 42 is generally larger than the cross-sectional area of the arched window runner 2; the gas outlet 44 is positioned on the side surface of the spherical gas chamber 43, and a gas sensor contact of the gas outlet 44 is connected with the alarm 45; and a flow blocking part 21 is arranged on the arched window flow passage 2, and the flow blocking part 21 is positioned at the end of the water outlet 3.
The working principle is described in detail: the gas in the water channel of the oral complex treatment table is removed by the principle that the gas-permeable and water-impermeable semipermeable membrane 42 only can permeate gas. The pressure reduction of the water inlet 1 in the arched window flow passage 2 adapts to the air permeable semi-permeable membrane 42 for air permeability. Because of the presence of the flow blocking elements 21 on the arched window channels 2, light water with gas always flows to the arch of the arched window channels 2 and is discharged by the gas-permeable semipermeable membrane 42.
Specifically, the bottom of the arched window flow channel 2 is communicated. The choke piece 21 is composed of a first choke piece 211 and a second choke piece 212, the first choke piece 211 is located at the bottom of the arched window flow channel 2, and the second choke piece 212 is located behind the connection position of the arched window flow channel 2 and the semi-permeable membrane air-filtering alarm mechanism 4. It is worth mentioning that the aperture of the first flow blocking element 211 is smaller than that of the second flow blocking element 212, so that most of the water flows to the camber of the cambered window flow passage 2. The first flow blocking part 211 and the second flow blocking part 212 are identical in structure and are unidirectional tapered passages 213; are formed by means of projections on the wall of the tube.
In some embodiments, a transparent viewing window 431 is disposed on the spherical gas chamber 43, and the viewing window 431 is located at the bottom of the spherical gas chamber 43. Because the gas-permeable semipermeable membrane 42 adopts the thickened GORE-TEX film, partial water vapor is not discharged to the spherical gas chamber 43, and the transparent observation window 431 just observes the condition and can give an early warning.
In some embodiments, a pressure relief valve 22 is provided at the water inlet of the arched window channel 2, and the pressure relief valve 22 is connected to the water supply pipeline. The pressure relief valve 22 is present to avoid transient overpressure in the water channel that could damage the permeable, semi-permeable membrane 42.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
