[0009] The sealing plate is arranged on the side of the layered plate away from the cup lid. Threaded posts are provided on the sealing plate, and a limiting block is fixedly arranged at the top of the threaded posts. The threaded posts are inserted into threaded holes and are threadedly connected to the connecting posts. The limiting block passes through the threaded holes and is slidably connected to the limiting posts. The limiting block and the limiting posts cannot rotate relative to each other. When the cup lid is opened, the limiting posts drive the threaded posts to rotate through the limiting blocks, causing the sealing plate to move towards the layered plate and close the communication hole.

[0010] Further, a limiting hole is axially formed in the limiting post, and the limiting block is inserted into the limiting hole, and the limiting block fits against the hole wall of the limiting hole.

[0011] Further, the cross-sections of both the limiting hole and the limiting block are square.

[0019] The beneficial effects of the present utility model are as follows:

[0020] 1. When the cup lid of the present utility model is tightened on the cup body, the sealing plate and the layered plate are in a separated state. At this time, the upper layer chamber and the lower layer chamber are communicated. When the cup lid is rotated, the limiting block will rotate together under the action of the limiting post. Since the sealing plate and the layered plate are threadedly connected through the threaded post and the connecting post, the threaded post and the connecting post will move relative to each other along the axial direction, thereby causing the sealing plate to move towards the layered plate and close the communication hole. At this time, the lower layer chamber is closed, and the liquid in the lower layer chamber will not be accidentally ingested by the patient.

[0021] 2. The present utility model realizes the sliding connection between the limiting block and the limiting post and the non-relative rotation therebetween by forming a limiting hole on the limiting post and inserting the limiting block into the limiting hole. The limiting block and the limiting hole can adopt a polygonal structure, such as a triangle, a quadrilateral, etc.

Detailed implementation mode

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] Embodiment 1

[0038] As Figure 1 shown, this embodiment provides an anti-reflux sputum cup, including a cup body 1, a cup cover 2 and an anti-reflux mechanism. The cup body 1 is a transparent structure. The anti-reflux mechanism includes a layered plate 501, a sealing plate 507 and a limiting post 510. The layered plate 501, the sealing plate 507 and the limiting post 510 are all located inside the cup body 1.

[0039] As Figure 4 shown, an internal thread is provided on the inner side of the cup cover 2. The cup cover 2 and the cup body 1 are threadedly connected to seal the cup body 1. The limiting post 510 is fixedly arranged at the top of the inner side of the cup cover 2. The upper end of the limiting post 510 is integrally formed with the cup cover 2. The limiting post 510 is axially provided with a limiting hole 511 from the lower end upwards.

[0040] As Figure 3 shown, the edge of the layered plate 501 is hermetically connected to the inner wall of the cup body 1. The layered plate 501 divides the inside of the cup body 1 into an upper chamber and a lower chamber. A plurality of communication holes 502 are provided on the layered plate 501. The communication holes 502 are used to communicate the upper chamber and the lower chamber. A connecting column 504 is provided at the center of the layered plate 501. The connecting column 504 is axially provided with a threaded hole 505. The lower end of the connecting column 504 penetrates through the layered plate 501.

[0041] As Figure 2As shown in the figure, the sealing plate 507 is arranged on the side of the layered plate 501 away from the cup lid 2. The diameter of the sealing plate 507 is smaller than the inner diameter of the cup body 1. When the cup lid 2 is tightened, the sealing plate 507 is separated from the layered plate 501. A threaded post 506 is provided at the center of the sealing plate 507. The lower end of the threaded post 506 is fixed on the sealing plate 507, and a limiting block 509 is fixedly arranged at the upper end of the threaded post 506. The threaded post 506 is inserted into the threaded hole 505 and is threadedly connected with the connecting post 504. The limiting block 509 passes through the threaded hole 505 and is slidably connected with the limiting post 510. The limiting block 509 and the limiting post 510 cannot rotate relative to each other. When the cup lid 2 is loosened, the sealing plate 507 will gradually approach the layered plate 501 and finally be in close contact with the layered plate 501, so that the communication hole 502 is closed.

[0042] In this embodiment, both the limiting hole 511 and the limiting post 510 are square, and the side length of the limiting post 510 is slightly smaller than the side length of the limiting hole 511.

[0043] In this embodiment, the threaded post 506, the limiting block 509, the connecting post 504, the threaded hole 505, the limiting post 510, and the limiting hole 511 are arranged along the axis of the cup body 1 and the cup lid 2.

[0044] As Figure 1 shown, a scale bar 4 is provided on the outer wall of the cup body 1, and an alignment bar 3 is provided on the outer wall of the cup lid 2. When the alignment bar 3 is aligned with the scale bar 4, the limiting block 509 can be inserted into the limiting hole 511.

[0045] As Figure 6 shown, a disinfection tablet 6 is placed at the bottom inside the cup body 1, and water can be directly added to the upper layer bin to prepare disinfected water. In addition, the volume of the upper layer bin can be set to the volume of water required to prepare disinfected water with a specific concentration. In this way, after filling the upper layer bin with water and covering the cup lid 2, disinfected water with a specific concentration can be prepared. In addition, the outer surface of the cup body 1 can be provided with concave and convex patterns to increase the friction with the palm and facilitate grasping and turning the cup lid 2.

[0046] The usage method of this anti-reflux sputum cup is as follows: Open the cup lid 2, the cup lid 2 drives the limit post 510 to rotate, the limit post 510 drives the limit block 509 to rotate, thereby causing the threaded post 506 to rotate. Since the threaded post 506 is threadedly connected to the connecting post 504, the rotation of the threaded post 506 will cause a relative axial movement between the threaded post 506 and the connecting post 504, causing the sealing plate 507 to move towards the layered plate 501 and close the communication hole 502. At this time, the lower chamber is in a sealed state. Add a certain amount of water to the upper chamber, align the alignment strip 3 with the scale strip 4, so that the limit block 509 is inserted into the limit hole 511 of the limit post 510, and then rotate the cup lid 2 to tighten the cup lid 2 on the cup body 1. During the process of rotating the cup lid 2, the threaded post 506 will also be driven to rotate. The rotation of the threaded post 506 will cause a relative axial movement between the threaded post 506 and the connecting post 504, causing the sealing plate 507 to move away from the layered plate 501 and open and close the communication hole 502. At this time, the lower chamber is in communication with the upper chamber, and the water in the upper chamber flows into the lower chamber to melt the disinfection tablet 6, thus completing the preparation of the disinfectant solution.

[0047] When the patient uses this anti-reflux sputum cup, open the cup lid 2, and the sealing plate 507 will close the communication hole 502, making the lower chamber in a sealed state, so that the patient cannot accidentally ingest the disinfectant solution in the lower chamber. After the patient spits out the sputum, tighten the cup lid 2, and the sealing plate 507 will separate from the layered plate 501, making the lower chamber in communication with the upper chamber, and the sputum can flow into the lower chamber through the communication hole 502 for disinfection.

[0048] Embodiment 2

[0049] Compared with Embodiment 1, the difference in Embodiment 2 is only the shape and size of the cup body 1. In this embodiment, the outer diameter of the bottom of the cup body 1 is smaller than the outer diameter of the cup lid 2, and the bottom of the cup body 1 is arc-shaped.

[0050] It can be understood that after the patient spits out the sputum and tightens the cup lid 2, since the bottom of the cup body 1 is small and arc-shaped and cannot be placed stably, the patient will invert the cup body 1 and place the cup lid 2 on the table. At this time, the disinfectant solution will flow from the lower chamber into the upper chamber to fully disinfect the upper chamber and the sputum in the upper chamber, so that before the patient uses it next time, the entire inside of the cup body 1 and the sputum are disinfected, avoiding the situation where the sputum cannot flow into the lower chamber. Tuberculosis patients can use the anti-reflux sputum cup of this embodiment, which is beneficial to reducing the pollution of the environment by sputum and the risk of spreading diseases, and protecting the health of others.

[0051] Embodiment 3

[0052] Compared with Embodiment 1, the difference in Embodiment 2 is only the structure of the sealing plate 507 and the layered plate 501; as Figure 7As shown, a circular sealing groove 503 is provided on the lower surface of the layered plate 501, and the communication hole 502 is within the range of the sealing groove 503. As Figure 6 shown, a sealing gasket 508 is fixedly provided on the upper surface of the sealing plate 507. The diameter of the sealing gasket 508 is equal to the diameter of the sealing groove 503, and the diameter of the sealing plate 507 is slightly larger than the diameter of the sealing groove 503, so that the sealing gasket 508 can be embedded in the sealing groove 503 to seal the communication hole 502.

[0053] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the protection scope of the present application.
