DETAILED DESCRIPTION

[0021] 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 of the embodiments.

[0022] Reference Figure 1-3 , a disposable electric sputum suction device comprises a shell 1 and a connecting tube 2, the connecting tube 2 is fixedly connected to the side wall of the shell 1, the inner wall of the shell 1 is provided with a cavity, the inner wall of the connecting tube 2 is fixedly connected with an adjusting box 3, the side wall of the adjusting box 3 is fixedly connected with a connecting tube 4, the bottom tube wall of the connecting tube 4 is fixedly connected with a sputum storage tank 5, the tube wall of the connecting tube 4 away from the adjusting box 3 is fixedly connected with a hose 6, the inner walls of the shell 1 on both sides of the cavity are fixedly connected with a magnetic ring 7, the inner wall of the shell 1 on the right side of the cavity is provided with a slot, the inner wall of the shell 1 on the slot is plugged with an environmentally friendly battery 9, the inner walls of the shell 1 on both sides of the cavity are fixedly connected with power boards 10, the two power boards 10 are electrically connected to the environmentally friendly battery 9, the top inner walls of the shell 1 on both sides of the cavity are provided with vents, the side walls of the electromagnet 8 are fixedly sleeved with a sealing ring 11, and the inner wall of the connecting tube 4 and the adjusting box 3 is fixedly connected with an isolation filter 12.

[0023] A through groove is provided on the inner wall of the electromagnet 8, and a transmission rod 13 is slidably provided on the inner wall of the through groove of the electromagnet 8. Two partitions 14 are hingedly provided on the end of the transmission rod 13 away from the electromagnet 8, and a guide block 15 is fixedly connected to the end of the partition 14 away from the transmission rod 13. A guide groove is provided on the inner wall of the adjustment box 3, and the guide block 15 is slidably set on the inner wall of the guide groove. The inner walls of the electromagnet 8 at both ends of the through groove are provided with card slots, and an elastic rubber card block 16 is fixedly connected to the end of the transmission rod 13 located inside the electromagnet 8. Both sides of the elastic rubber card block 16 are set as arc surfaces, and the inner wall of the electromagnet 8 at the connection between the through groove and the card slot is provided with a chamfer.

[0024] When in use, the device can be powered by plugging the environmentally friendly battery 9 into the slot of the housing 1. After power is connected, the power boards 10 on both sides can respectively energize and magnetize the electromagnet 8. After power is turned on, the magnetic poles on both sides of the electromagnet 8 are respectively the same as the magnetic poles on the corresponding side of the magnetic rings 7 on both sides. According to the principle that like poles repel each other and opposite poles attract each other, the magnetic rings 7 on both sides can respectively repel and push the electromagnet 8 after power is turned on, so that the electromagnet 8 slides along the inner wall of the cavity. The sealing ring 11 can improve the sealing performance of the electromagnet 8 sliding on the inner wall of the cavity.

[0025] When the electromagnet 8 slides to the right, negative pressure can be generated inside the cavity of the shell 1, and at the same time, the transmission rod 13 will be pulled to move. The transmission rod 13 will pull the partition 14 open, so that the interior of the regulating box 3 can be affected by the negative pressure inside the cavity of the shell 1, so that the gas inside the hose 6 flows to the interior of the regulating box 3 through the connecting pipe 4, so that the hose 6 can extract the patient's sputum. In order to ensure the efficiency of sputum suction, after the partition 14 is opened, the transmission rod 13 will still move with the electromagnet 8 until the elastic rubber block 16 is deformed by excessive pressure and slides along the inside of the through groove to the inside of another groove. At the same time, the electromagnet 8 stops moving to the right, and the subsequent electromagnet slides to the left, which can make the electromagnet 8 push the elastic rubber block 16 to move to the inside of the through groove. The rubber block 16 and the transmission rod 13 move, and can push the partition 14 to slide along the inner wall of the guide groove through the guide block 15, so that the partition 14 is quickly closed on the inner wall of the adjustment box 3, so that the adjustment box 3 can be kept closed, and the sputum adsorbed to the inside of the connecting tube 4 can be made to fall into the inside of the sputum storage tank 5. The isolation filter 12 can prevent the sputum from extending into the inside of the adjustment box 3. After the partition 14 is closed, the electromagnet 8 will still move to the left until it contacts the power board 10 on the left. At this time, in order to quickly adjust the partition 14 later, the elastic rubber block 16 is deformed by excessive pressure and slides along the inside of the through groove to the inside of another card slot, and at the same time, the excess gas will flow out through the vent hole at the top of the shell 1;

[0026] The shell 1, the connecting tube 2, the regulating box 3, the connecting tube 4 and the sputum storage tank 5 are all made of medical healthy resin materials, which can not only improve the safety during use, but also facilitate recycling after the subsequent material disassembly, thereby reducing pollution to the environment and waste of resources.

[0027] In order to prevent the gas from flowing into the cavity through the vent hole when the electromagnet 8 slides to the right, affecting the negative pressure environment inside the cavity, such as Figure 1-3 As shown, a pressure relief cylinder 17 is fixedly connected to the top of the shell 1, a spring 18 is fixedly connected to the inner wall of the top of the pressure relief cylinder 17, a rubber plug 19 is fixedly connected to the bottom of the spring 18, a pressure relief hole is opened on the inner wall of the pressure relief cylinder 17, and the side wall of the rubber plug 19 is slidably arranged on the inner wall of the pressure relief cylinder 17, and an end cover 20 is threadedly connected to the inner wall of the top of the shell 1 located in the slot.

[0028] In order to prevent the gas from flowing into the interior of the cavity through the vent when the electromagnet 8 slides to the right, affecting the negative pressure environment inside the cavity, the spring 18 and rubber plug 19 inside the pressure relief cylinder 17 can prevent the gas from entering the interior of the shell 1 from the inner wall of the left vent, so that the interior of the shell 1 can maintain a negative pressure state, thereby ensuring that sputum can enter the interior of the connecting tube 4 through the hose 6. During subsequent pressure relief, the spring 18 and the rubber plug 19 are moved upward by pressure, so that the gas can be moved out through the pressure relief hole inside the pressure relief cylinder 17, thereby ensuring the pressure relief effect. The end cover 20 can limit the environmentally friendly battery 9 to ensure the stability of the environmentally friendly battery 9 during use. At the same time, the pictorial battery 9 can be flexibly disassembled after use, which is convenient for subsequent material recycling.

[0029] 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
