DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Example 1, reference Figure 1 and Figure 2 The present embodiment is a device for suctioning sputum, comprising a shell 10, on which an air inlet pipe 20 and an air exhaust pipe 30 are arranged, wherein the air inlet pipe is located at the top end of the shell and is arranged close to one side of the shell, and the air exhaust pipe is arranged close to the other side of the shell; an electric heating plate 40 is arranged obliquely in the shell, and the motor heating plate is located below the air inlet pipe and is arranged close to one side of the air inlet pipe at the top end; a water inlet pipe 50 is arranged on the shell, and a water spray structure connected to the water inlet pipe is arranged in the shell at a position corresponding to the electric heating plate.

[0017] The water spray structure includes a water tank 60 arranged in parallel with the electric heating plate, and a plurality of first water spray holes 60-1 are arranged on the bottom surface of the water tank; a shielding plate 70 is slidably arranged on the bottom surface of the water tank, and a second water spray hole 70-1 is arranged on the shielding plate at a position corresponding to the first water spray hole, and a telescopic device 80 for driving the shielding plate to move is installed on the shell. The telescopic device can be a linear motion motor, a hydraulic cylinder or an electric telescopic rod, etc.

[0018] When the above-mentioned sputum suction device is manufactured or used, the exhaust pipe is connected to an induced draft fan or a negative pressure generator, and the air inlet pipe is connected to a negative pressure pipe, which is used to extend into the throat and other parts of the human body. The induced draft fan or the negative pressure generator works to generate negative pressure in the shell, and 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. Since the electric heating plate is inclined, the sputum is more likely to 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 baking effect 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 spray hole of the baffle plate partially overlaps with the first water spray hole of the water tank, so that the diameter of the water column sprayed by the water tank is smaller. When it falls on the electric heating plate, a large amount of water vapor is instantly generated to disinfect the inside of the shell at high temperature. In this process, part of the carbonized sputum floats with the water vapor and is discharged through the exhaust pipe. After high-temperature disinfection, the telescopic device drives the baffle plate to move, so that the first water spray hole and the second water spray hole overlap. The diameter of the water column sprayed by the water tank is larger, and the water column falls on the electric heating plate to flush the residual sputum, thereby cleaning the electric heating plate.

[0019] As an embodiment, the exhaust pipe includes a first exhaust pipe 30-1 and a second exhaust pipe 30-2, and the position where the first exhaust pipe is connected to the shell is located on the top surface of the shell. In this way, when the first exhaust pipe is used to inhale air, due to the obstruction of the water tank, the airflow flows to the first exhaust pipe through the lower part of the water tank, which is convenient for the sputum to fall quickly; the connection position between the second exhaust pipe and the shell is located on the side of the shell, and is located between the electric heating plate and the baffle plate. In this way, when the second exhaust pipe is used to inhale air, it is convenient to adsorb the water vapor generated on the motor hot plate; the end of the first exhaust pipe not connected to the shell is connected to the end of the second exhaust pipe not connected to the shell; a first solenoid valve 30-3 is provided on the first exhaust pipe, a second solenoid valve 30-4 is provided on the second exhaust pipe, a third solenoid valve 50-1 is provided on the water pipe, a drain pipe 90 is provided at the bottom of the shell, and a fourth solenoid valve 100 is installed on the drain pipe. In this structure, when suctioning sputum, the first solenoid valve is opened, the second solenoid valve, the third solenoid valve and the fourth solenoid valve are closed, and the induced draft fan or the negative pressure generator works, so that negative pressure is generated in the shell, and 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; when the 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 solenoid valve is closed, the third solenoid valve is opened, and water is supplied to the water tank through the water inlet pipe. When the water supply starts, the diameter of the water column sprayed from the water tank is small, and when it falls on the electric heating plate, a large pressure is instantly generated. Amount of water vapor is used to sterilize the inside of the shell at high temperature. During this process, part of the carbonized sputum floats with the water vapor. At this time, the second solenoid valve is opened, and the water vapor carries part of the carbonized sputum to be discharged through the exhaust pipe to prevent the carbonized sputum from accumulating in the position of the drainage pipe after flushing, causing blockage of the drainage pipe; after high-temperature disinfection, the telescopic device drives the baffle plate to move, so that the first water spray hole and the second water spray hole overlap, the water column sprayed by the water tank has a larger diameter, and the water column falls on the electric heating plate to flush the residual sputum, flush the electric heating plate clean, and then open the fourth solenoid valve to discharge the liquid.

[0020] Example 2, reference Figure 3 The structure of Example 2 is roughly the same as that of Example 1, except that no shielding plate is provided on the water tank, but the first water spray hole is provided with a diameter smaller than that of the example, a bypass pipe 50-2 is provided on the water inlet pipe, a fifth solenoid valve 50-3 is installed on the bypass pipe, a nozzle 110 connected to the bypass pipe is provided in the shell, and the nozzle is located between the water tank and the air inlet pipe. When a large amount of water vapor needs to be generated, the third solenoid valve is opened and the fifth solenoid valve is closed. When the electric heating plate needs to be flushed, the fifth solenoid valve is opened and the third solenoid valve is closed. The above-mentioned nozzle can be tilted relative to the electric heating plate, such as tilted upward or downward, to facilitate the water column to flush the electric heating plate.

[0021] It should be noted that the water spray structure in the above embodiment can also be other structures, as long as it can be adjusted so that the water spray structure can spray water columns of different sizes. No specific limitation is made here. Of course, the water spray structure must be located above the electric heating plate to facilitate flushing of the electric heating plate.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
