DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application.

[0021] Embodiment 1, refer to Figure 1 and Figure 2 The present embodiment is a sputum suction device, comprising a shell 10, an air inlet pipe 20 and an air outlet pipe 30 are arranged on the shell, the air inlet pipe is arranged at the top of the shell and close to one side of the shell, and the air outlet pipe is arranged close to the other side of the shell; an electric heating plate 40 is arranged in the shell in an inclined manner, the electric heating plate is arranged below the air inlet pipe and close to one side of the air inlet pipe at the top; a water inlet pipe 50 is arranged on the shell, and a water spraying structure communicating with the water inlet pipe is arranged in the shell and corresponds to the position of the electric heating plate.

[0022] The water spraying structure comprises a water tank 60 arranged in parallel with the electric heating plate, a plurality of first water spraying holes 60-1 are arranged on the bottom surface of the water tank; a shielding plate 70 is arranged on the bottom surface of the water tank in a sliding manner, a second water spraying hole 70-1 is arranged on the shielding plate and corresponds to the position of the first water spraying hole, and a telescopic device 80 for driving the shielding plate to move is mounted on the shell. The telescopic device can be a linear motion motor, a hydraulic cylinder or an electric telescopic rod.

[0023] When the sputum suction device is manufactured or used, the air outlet pipe is connected with an air blower or a negative pressure generator, and a negative pressure pipe is connected to the air inlet pipe, the negative pressure pipe is used to extend into the throat and other parts of the human body, the air blower or the negative pressure generator is operated to generate negative pressure in the shell, sputum enters the shell through the negative pressure pipe and the air outlet pipe, and falls on the electric heating plate under the action of gravity. Since the electric heating plate is arranged in an inclined manner, the sputum is more easily spread downward under the action of inertia. After the sputum suction operation is completed, the electric heating plate is powered on, and the sputum is carbonized under the roasting action of the electric heating plate. After the sputum is carbonized, water is supplied to the water tank through the water inlet pipe. In the original state, the second water spraying hole of the shielding plate partially overlaps the first water spraying hole of the water tank, so that the water column sprayed by the water tank has a small diameter. When the water column falls on the electric heating plate, a large amount of water vapor is generated instantaneously, the inside of the shell is sterilized at high temperature, and part of the carbonized sputum floats with the water vapor and is discharged through the air outlet pipe. After high-temperature sterilization, the telescopic device drives the shielding plate to move, so that the first water spraying hole and the second water spraying hole overlap, the water column sprayed by the water tank has a large diameter, and the water column falls on the electric heating plate to flush the residual sputum and clean the electric heating plate.

[0024] As an embodiment, the exhaust pipe comprises a first exhaust pipe 30-1 and a second exhaust pipe 30-2, the first exhaust pipe is connected to the top surface of the shell, so that when the first exhaust pipe is used to suck air, the air flows to the first exhaust pipe through the lower part of the water tank due to the obstruction of the water tank, facilitating the rapid falling of sputum; the second exhaust pipe is connected to the side surface of the shell and is located between the electric heating plate and the shielding plate, so that when the second exhaust pipe is used to suck air, it is convenient to suck the water vapor generated on the electric heating plate; the end of the first exhaust pipe not connected to the shell is communicated with the end of the second exhaust pipe not connected to the shell; the first electromagnetic valve 30-3 is arranged on the first exhaust pipe, the second electromagnetic valve 30-4 is arranged on the second exhaust pipe, the third electromagnetic valve 50-1 is arranged on the water pipe, the bottom of the shell is provided with a liquid discharge pipe 90, and the fourth electromagnetic valve 100 is installed on the liquid discharge pipe. When sputum is sucked, the first electromagnetic valve is opened, the second electromagnetic valve, the third electromagnetic valve and the fourth electromagnetic valve are closed, the air blower or the negative pressure generator is operated, the negative pressure is generated in the shell, the sputum enters the shell through the negative pressure pipe and the exhaust pipe, and falls on the electric heating plate under the action of gravity; after the sputum suction operation is completed, the electric heating plate is powered on, so that the electric heating plate dries and carbonizes the sputum; then the first electromagnetic valve is closed, the third electromagnetic valve is opened, water is supplied to the water tank through the water inlet pipe, the water column diameter of the water tank is small when the water supply starts, a large amount of water vapor is generated instantaneously when the water column falls on the electric heating plate, the inside of the shell is sterilized at high temperature, and part of the carbonized sputum floats with the water vapor in this process; at this time, the second electromagnetic valve is opened, the water vapor carries part of the carbonized sputum out of the exhaust pipe, preventing the carbonized sputum from accumulating in the position of the liquid discharge pipe after being flushed, causing the liquid discharge pipe to be blocked; after high-temperature sterilization, the telescopic device drives the shielding plate to move, so that the first water spraying hole and the second water spraying hole are coincided, the water column diameter of the water tank is large, the water column falls on the electric heating plate to flush the residual sputum, and then the fourth electromagnetic valve is opened to discharge the liquid.

[0025] Embodiment 2, refer to Figure 3 Embodiment 2 is substantially the same as embodiment 1, the difference is that the shielding plate is not arranged on the water tank, but the first water spraying hole is arranged to be smaller in diameter than embodiment, a bypass pipe 50-2 is arranged on the water inlet pipe, a fifth electromagnetic valve 50-3 is installed on the bypass pipe, a spray head 110 is arranged in the shell and communicated with the bypass pipe, and the spray head is located between the water tank and the air inlet pipe; when a large amount of water vapor is needed, the third electromagnetic valve is opened and the fifth electromagnetic valve is closed; when the electric heating plate needs to be flushed, the fifth electromagnetic valve is opened and the third electromagnetic valve is closed. The spray head described above can be inclined relative to the electric heating plate, such as upward or downward inclination, facilitating the water column to flush the electric heating plate.

[0026] It should be noted that the water spraying structure in the above embodiment can also be other structures, as long as it can be adjusted so that the water spraying structure can spray water columns of different sizes, which is not specifically limited here. Of course, the water spraying structure is located above the electric heating plate to facilitate washing the electric heating plate.

[0027] The above description is merely preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art, according to the technical range disclosed in the present application and the inventive concept, can make equivalent replacements or changes within the technical range disclosed in the present application, which should be covered within the protection scope of the present application.
