Certainly, in order to improve the connection sealing performance between the bottle cap 2 and the bottle body 1, a sealing ring 23 is arranged inside the bottle cap 2, wherein the sealing ring 23 may specifically adopt a frameless rubber ring, so that the outer side wall of the sealing ring is tightly attached to the inner side wall of the bottle body 1, so as to strengthen the sealing and avoid water leakage.
It is worth mentioning that the tube cap of the centrifuge tube can be directly used as the bottle cap 2 because the existing centrifuge tube is generally provided with the tube cap (the tube cap is screwed at the open end of the centrifuge tube).
As shown in fig. 1, the pressure stabilizer 3 is disposed on the side wall of the closed end of the bottle body 1, and the pressure stabilizer 3 is disposed in a hollow manner to form an air flow passage (not shown in the view angle reason), which is linear, for communicating the inside of the bottle body 1 with the outside air through the air flow passage, specifically: one end of the air flow channel is communicated with the inside of the bottle body 1, the other end of the air flow channel is arranged outside the bottle body 1 and is communicated with the external environment, and air is supplemented into the bottle body 1 through the air flow channel so as to balance the air pressure in the bottle body 1.
It should be noted that the diameter of the air flow passage in the pressure stabilizer 3 ranges from 0.35mm to 0.6mm, and the diameter of the air flow passage, i.e. the diameter of the air flow passage, is too large or too small, which affects the water outlet effect of the water outlet member 4.
In a preferred embodiment, the air flow passage has a diameter of 0.45 mm.
In this embodiment, the stabilizer 3 can use the existing 1m l standard syringe needle, in other words, the existing 1ml standard syringe needle is used as the stabilizer 3, so that the injection channel inside the needle can be used as the air flow channel in this embodiment; because the injection passage of the needle head is smaller, the syringe needle can be used as an air flow passage for communicating the interior of the bottle body 1 with the external air pressure, the material is convenient to obtain, and the cost is low.
Moreover, because the head end (the needle point end) of the syringe needle is sharp needle-shaped, when the needle is assembled on the bottle body 1, a blind hole (namely, the hole does not directly penetrate through the wall of the bottle body 1) can be firstly drilled on the outer wall of the bottle body 1, the blind hole is mainly used for reducing the wall thickness of the bottle body 1, then, the sharp end of the needle can be directly punctured into the wall of the blind hole, at the moment, the needle is inserted into the bottle body 1, because the needle directly punctures the bottle body 1, the connection position (namely, the puncture position) of the needle and the bottle body 1 is very tightly matched at the moment, almost no gap exists, higher sealing performance can be realized, and extra sealing processing at the connection position is not needed.
The water outlet member 4 is mounted on the bottle cap 2, and a water outlet channel (not shown in the figure for reasons of visual angle) is formed in the hollow part of the water outlet member, and the water in the bottle body 1 is guided out through the water outlet channel for animals to drink, it is worth mentioning that the water outlet channel is linear, and one end of the water outlet channel is provided with water inlet, namely a water inlet end, and the other end of the water outlet channel is provided with water outlet, namely a water outlet end, wherein the diameter range of the water outlet end is 0.4mm-1.0mm, and the diameter refers to the caliber of the water outlet end.
