In this embodiment, the first pipe 4 and the second pipe 5 are configured as hoses, specifically hoses used for common sputum suction equipment, which have a corresponding bendable effect; this is prior art and is not described in detail here.

[0037] The upper end of the cylinder shell 61 is movably connected with an adapter 63, and the adapter 63 is connected to the suction piece 7; the adapter 63 is movably fixed in the cylinder shell 61, and the lower end of the adapter 63 is connected to one end of the alignment tube 62 and can be rotated, while maintaining a sealing effect, forming a connecting effect, which can facilitate all-round cleaning when disassembling.

[0038] The suction piece 7 is detachably connected to the other end of the handheld component 6, which is convenient for disassembling and replacing the suction piece 7; the position of the suction piece 7 is adjusted by rotating the handheld component 6; it is convenient to change the position at any time during suction, which is conducive to adsorbing sputum.

[0039] The sputum suction piece 7 includes a main pipe 71, one end of which is detachably fixedly connected to the adapter 63, and the other end of the main pipe 71 is connected to the work pipe 72. A notch 721 is provided on one end of the work pipe 72. The notch 721 can prevent the work pipe 72 from being blocked when it contacts the surface tissue, thereby facilitating the adsorption of sputum; a spare port 722 is provided on the outer peripheral side of the work pipe 72, and a sealing sleeve 73 is provided on the work pipe 72. The sealing sleeve 73 slides over the spare port 722 so that it can be opened for standby when the end of the work pipe 72 or the notch 721 is blocked, thereby improving the fault tolerance of use;

[0040] Two convex rings are provided on the outer circumference of the station tube 72 , and the sleeve 73 can slide between the two convex rings, thereby limiting the sliding range of the sleeve 73 and realizing the initial position setting of the sleeve 73 at the same time.

[0041] The adjustment component 8 is detachably fixed to the handheld component 6, and the suction port of the sputum suction piece 7 can be adjusted by pulling the adjustment component 8 during operation; the adjustment component 8 includes a columnar component 81 detachably fixed to the adapter 63, and the columnar component 81 includes two threaded rods threadedly connected to the handheld component 6 and a sleeve plate rotatably connected; a movable plate 82 is slidably sleeved on the columnar component 81, and a circular hole is machined in the middle of the movable plate 82 for the sputum suction piece 7 to pass through, and a traction rope 83 that can pull the cover 73 is connected to the movable plate 82, and both ends of the traction rope 83 are detachably connected to the corresponding components;

[0042] The alarm component 9 is arranged on the top of the sputum cup 3. When the sputum suction port of the sputum suction member 7 is blocked, the alarm component 9 is activated by the negative pressure. The alarm component 9 includes a round box 91 fixed on the sputum cup 3. The bottom of the round box 91 is provided with an air vent so that the round box 91 is connected with the inside of the sputum cup 3. When the inside of the sputum cup 3 is under negative pressure, the inside of the round box 91 is also under negative pressure. A battery component 92 is fixed to the inner bottom of the round box 91. Contacts of the positive and negative electrodes of the battery component 92 are respectively provided on both ends of the battery component 92. A movable component 93 is slidingly provided in the round box 91. The piston sliding is used to ensure the sealing. In this embodiment, Specifically, a rubber sealing ring is provided on the outer periphery of the movable member 93 to improve the sealing performance; a return spring 95 is provided between the lower side of the movable member 93 and the round box 91 for support, and the return spring 95 can be compressed by the action of negative pressure difference. A buzzer 94 is provided on the movable member 93 to provide an alarm function. The positive and negative terminals of the buzzer 94 are respectively connected to electrode springs. When the buzzer 94 sounds an alarm, the electrode springs contact the positive and negative electrode contacts, forming power supply to the buzzer 94, thereby completing the alarm function. A locking plug 96 is provided in the round box 91 to prevent the movable member 93 from sliding out of the round box 91.

The cup cover is provided with a mounting hole, and the mounting hole is provided with threads corresponding to those on the outer circumference of the round box 91, so as to facilitate assembly.

[0044] During operation, when the suction unit 1 is in operation, negative pressure is applied to the sputum cup 3 via pipe 1 4. This pressure causes the return spring 95 to descend a certain distance, causing the movable element 93 to slide. However, at this time, the buzzer 94 is not powered by the battery 92. Since the sputum cup 3 is connected to the handheld assembly 6 and the suction unit 7, respectively, via pipe 2 5, the suction unit 7 absorbs the suction area, drawing sputum from the suction unit 7 through the work tube 72 and the notch 721 into the main pipe 71. The sputum then flows through the adapter 63, the alignment pipe 62, and then through pipe 2 5 into the sputum cup 3. If the end of the work tube 72 encounters human tissue or large foreign matter, it may become clogged. When the work tube 72 is adsorbed onto the human tissue, the gap 721 can reduce the situation that the end of the work tube 72 is adsorbed onto the human tissue; when the work tube 72 is adsorbed onto a large piece of foreign matter, the gap 721 is not sufficient to meet the demand, and the work tube 72 is blocked; at this time, the work tube 72 cannot enter air or sputum, thereby increasing the negative pressure in the sputum cup 3, and the pressure in the round box 91 is reduced at the same time. At this time, the sliding of the movable part 93 cooperates with the force compression of the return spring 95, and the buzzer part 94 will form power supply with the battery part 92, and the buzzer part 94 is started to sound an alarm, which can prompt the operator to move the suction port of the sputum suction part 7; at this time, the movable plate 82 is pulled, and the cover 73 and the work tube 72 are pulled by the pull rope 83 to slide, exposing the spare port 722 to open, and sputum can be suctioned through the spare port 722, thereby improving the use of the backup solution when the foreign matter is adsorbed and blocked, thereby improving the fault tolerance rate.

[0045] Example 2

[0046] This embodiment is further optimized based on the first embodiment, and the parts that are the same as the above technical solutions will not be repeated here. Figure 3-5 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0047] A sleeve 611 is provided at the upper end of the cylindrical shell 61 , and the inner ring of the sleeve 611 is provided with at least one annular groove; in this embodiment, the number of the annular grooves is set to three.

[0048] The lower end of the cylindrical shell 61 is provided with a threaded portion, which is threadedly connected to the alignment tube 62. The upper end of the cylindrical shell 61 is provided with a sleeve 611, and the inner ring of the sleeve 611 is provided with at least one annular groove;

[0049] The adapter 63 includes a plug-in portion, a knob portion, and a pipe portion. The plug-in portion is provided with at least one annular groove, within which is located a rubber ring 64 that aligns with the annular groove when plugged in. In this embodiment, there are three annular grooves and three rubber rings 64. The knob portion is provided with anti-slip grooves.

[0050] The cylindrical shell 61 is hollow and its lower end is narrowed in the axial and radial directions. A limiting ring is fixed on the cylindrical shell 61. A placement position is provided on one side of the sputum cup 3. The narrowing of the lower end facilitates the placement of the cylindrical shell 61.

[0051] In order to meet the demand for a more precise suction position of the work station tube 72, when adjusting the angle of the suction piece 7, the adapter 63 is rotated with the thumb by holding the cylinder shell 61. Due to the use of the plug-in method and the annular groove, rubber ring 64 and annular groove; the rotation method can be used to achieve adjustment, thereby meeting the angle adjustment of the specified position during suction, avoiding the deviation of the suction position, and improving the accuracy of the suction position; at the same time, the rotatable feature can be used to reduce the adsorption of human tissue during suction.

[0052] The above are only preferred embodiments of the present invention and are intended to be illustrative rather than restrictive. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the embodiments within the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
