In a preferred embodiment of the present invention, the base 1 is provided with indication marks 12 on the outer side, and the extension tube 2 is provided with at least two height marks and an angle mark corresponding to each height mark;
when the extension tube 2 moves relative to the base 1 to a position where one of the height marks has a predetermined height relative to the base 1 and the extension tube 2 rotates to a position where the angle mark corresponding to the height mark has a predetermined angle relative to the indication mark 12, the nozzle 25 can be aligned with a predetermined position of the nasal cavity to spray when the extension tube 2 extends into the nasal cavity. Wherein, the angle described in the present application is an angle centered on the center of the telescopic tube 2.
Preferably, the height mark is made to have a predetermined height with respect to the base 1 by moving the telescopic tube 1 to align the height mark with the upper edge of the opening 11 of the base 1. Of course, it is also possible to align the height marks with other structures on the base 1.
Specifically, as shown in fig. 4 and 5, the telescopic tube 2 is open at the bottom end, closed at the top end and provided with a nozzle 25 on the side wall of the top end, and two height marks, a first height mark 21 and a second height mark 23, and two angle marks, a first angle mark 22 and a second angle mark 24, are provided on the outer side surface of the telescopic tube 2. The first height mark 21 corresponds to the first angle mark 22, which is used in combination, and the second height mark 23 corresponds to the second angle mark 24, which is used in combination.

When the second height mark 23 is aligned with the upper edge of the opening on the base 1 and a third angle (for example, 90 °) is formed between the second angle mark 24 corresponding to the second height mark 23 and the indication mark 12 on the base 1, the extension tube 2 is inserted into the nasal cavity and the nozzle 25 can be ejected in alignment with a third predetermined portion of the nasal cavity.
When the second height mark 23 is aligned with the upper edge of the opening of the base 1 and a fourth angle (for example, 0 °) is formed between the second angle mark 24 corresponding to the second height mark 23 and the indication mark 12 on the base 1, the extension tube 2 is inserted into the nasal cavity and the nozzle 25 can be ejected in alignment with a fourth predetermined portion of the nasal cavity.

When the telescopic tube 2 moves relative to the base 1 to a position where one of the height marks has a predetermined height relative to the base 1 and the telescopic tube 2 rotates to a position where the nozzle 25 has a predetermined angle relative to the indication mark 12 of the base 1, the nozzle 25 can be aligned with a predetermined position of the nasal cavity to spray when the telescopic tube 2 is inserted into the nasal cavity. That is to say, the angle to be adjusted of the telescopic tube 2 is determined directly by the angular position of the spout 25 with respect to the indicator mark 12 on the base 1.
The preset angle of the nozzle 25 relative to the indication mark 12 of the base 1 can be obtained through a visual estimation mode, and the nozzle 25 of the telescopic tube 2 is rotated to a certain position, so that when the nozzle 25 and the indication mark 12 are approximately within a certain angle range, the nozzle 25 can be aligned to a preset position of the nasal cavity in use.
In another mode, in order to facilitate the angle between the nozzle 25 and the indication mark 12 of the base 1, a straight line extending from the nozzle 25 to the base 1 may be provided on the extension tube 2, and when the extension tube 2 is rotated to have a predetermined angle between the straight line and the indication mark 12, that is, the predetermined angle between the nozzle 25 and the indication mark 12 is indicated.
In this embodiment, the base 1 is preferably made of a flexible silicone material.
The base 1 may be of a construction as shown in figures 2 and 3, the base 1 comprising a conical portion with an outer diameter tapering in a direction towards the tip of the telescopic tube 2.
The indication mark 12 on the base 1 is a protrusion arranged on the outer surface of the base 1.
One end of the base 1, which is far away from the top end of the extension tube 2, is provided with a connecting structure, and the connecting structure is used for being connected with a structure at an opening of a liquid container. Preferably, the connecting structure is an annular groove 13 arranged on the inner side of the end of the base 1 away from the top end of the telescopic tube 2, and the annular groove 13 is used for being matched and connected with an annular projection 33 at the opening of the liquid container (refer to fig. 7 and the following description).
Preferably, the opening 11 of the base 1 is cooperatively arranged with the extension tube 2, and the extension tube 2 maintains the position of the extension tube 2 relative to the base 1 by friction with the side wall of the opening 11. That is, the telescopic tube 2 can be moved and rotated when a force is applied to the telescopic tube 2 that overcomes the friction between the telescopic tube 2 and the base 1, the telescopic tube 2 being held in a predetermined relative position with respect to the base 1 by means of friction when the telescopic tube 2 is adjusted to this position.
