[0024] Example 1

[0025] like Figures 1 to 3 As shown, this embodiment discloses a connection and matching structure of a nasal spray, wherein the nasal spray consists of a main body 1 and a nasal washing head 2 connected to the upper end of the main body 1; a nozzle 19 is obliquely arranged on the nasal washing head 2, and a control button 18 is arranged on the side wall of the main body 1.

[0026] Specifically, the connection and matching structure of this embodiment is used to connect the nose washing head 2 and the main body 1, and includes a connection sleeve 3 arranged at the lower end of the nose washing head 2 and a connection cavity 6 arranged at the upper end of the main body 1. The outer wall of the connection sleeve 3 is provided with a male thread 4, and the cavity wall of the connection cavity 6 is provided with a female thread 9 that can match the male thread 4. When connected, the connection sleeve 3 is screwed into the connection cavity 6 through the cooperation of the male thread 4 and the female thread 9, so that the nose washing head 2 is installed on the main body 1.

[0027] In addition, a positioning structure is also provided in the connecting cavity 6. When the connecting sleeve 3 is screwed into the connecting cavity 6, the thread starting point 20 on the male thread 4 can abut against the positioning structure to limit the nose wash head 2, so that the nozzle 19 on the nose wash head 2 and the control button 18 on the main body 1 face in the same direction, thereby improving the user experience.

[0028] Specifically, the positioning structure includes a first thread notch 12 and a second thread notch 11 symmetrically arranged on the cavity wall of the connecting cavity 6 with the axis of the main body 1 as the center; the first thread notch 12, the second thread notch 11 and the control button 18 are located on the same vertical plane, and the first thread notch 12 is located on the side close to the control button 18, and the starting point of the female thread 9 is located on the side of the second thread notch 11, so the connecting sleeve 3 can only be screwed into the connecting cavity 6 from the position of the second thread notch 11, such as Figure 3 shown.

[0029] In addition, a long limiting rib 7 is provided in the first thread notch 12, and the thread starting point 20 on the male thread 4 is oriented in the same direction as the nozzle 19, such as Figure 2 shown.

[0030] During installation, align the thread starting point 20 on the male thread 4 with the position of the second thread notch 11, and screw the connecting sleeve 3 into the connecting cavity 6 starting from the position of the second thread notch 11. When the thread starting point 20 abuts against the long limiting rib 7, the installation of the nose wash head 2 is completed. At this time, the nozzle 19 on the nose wash head 2 and the control button 18 on the main body 1 are facing the same direction.

[0031] In addition, the long limiting rib 7 extends upward from the bottom of the connecting cavity 6 to the upper surface of the main body 1 , so that the user can better see the long limiting rib 7 , so as to confirm the installation direction of the nose washing head 2 .

[0032] As another preferred solution, the male thread 4 and the female thread 9 are both double thread structures, and in this case, the male thread 4 has two thread starting points 20. In a specific configuration, the two thread starting points 20 are symmetrically distributed with the axis of the connecting sleeve 3 as the center.

[0033] Correspondingly, a short limiting rib 8 is provided in the second thread notch 11, and the length of the short limiting rib 8 is shorter than the length of the long limiting rib 7. During installation, the thread starting point 20 facing the same direction as the nozzle 19 is aligned with the position of the second thread notch 11, and the connecting sleeve 3 is screwed into the connecting cavity 6 from the position of the second thread notch 11. The nose washing head 2 only needs to be rotated 180 degrees to complete the installation. At this time, the thread starting point 20 facing the same direction as the nozzle 19 abuts against the long limiting rib 7, and the thread starting point 20 away from the nozzle 19 abuts against the short limiting rib 8.

[0034] The short limiting rib 8 is set to be short, so that the connecting sleeve 3 can be easily screwed into the connecting cavity 6 from the second thread notch 11. The male thread 4 and the female thread 9 adopt a double thread structure design to ensure the stability of the connection between the nose washing head 2 and the main body 1 when the length of the connecting sleeve 3 is limited.

It should be noted that the nose washing head 2 includes a bottom plate 13 and a shell 14 disposed on the bottom plate 13, a medicine storage cavity 15 is formed between the bottom plate 13 and the shell 14, the nozzle 19 is connected to the medicine storage cavity 15, and the connecting sleeve 3 is disposed below the bottom plate 13. The structure of the nose washing head 2 and the main body 1 has been disclosed in the patent technology with application number 2023225648906, so its detailed structure is not repeated here.

[0037] This embodiment optimizes the sealing performance between the bottom plate 13 and the housing 14. Figure 4 , 5As shown, in this embodiment, a sealing ring 17 is provided on the side wall of the bottom plate 13 . When the housing 14 is mounted on the bottom plate 13 , the sealing ring 17 is pressed against the side wall of the housing 14 , thereby forming a seal between the housing 14 and the bottom plate 13 .

[0038] In addition, an annular groove is provided on the bottom plate 13, and an annular boss 16 is provided at the lower end of the shell 14. When the shell 14 is mounted on the bottom plate 13, the annular boss 16 is inserted into the annular groove 5. Through the cooperation of the annular boss 16 and the annular groove 5, a second seal is formed between the shell 14 and the bottom plate 13, thereby improving the sealing performance between the shell 14 and the bottom plate 13.
