[0042] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered.

[0043] Example 1:

[0044] like Figure 1 As shown, this embodiment provides a watering device for rodent laboratory animals, including a bottle body 1, a bottle cap 2, a water outlet 4, and a pressure stabilizing component 3. Specifically:

[0045] The bottle 1 is open at one end and closed at the other end. It is mainly used to hold drinking water for animals. In order to make it easy to observe the actual water volume in the bottle 1, in this embodiment, the bottle 1 is made of transparent material, and the bottle 1 is provided with scale lines 11 distributed along the axis of the bottle 1; thus, the water volume in the bottle 1 can be directly read from the scale lines 11.

[0046] Among them, such as Figure 1 and Figure 2 As shown, the bottle body 1 can be a 50ml plastic centrifuge tube that is already available in the laboratory. The existing centrifuge tube is mainly made of transparent plastic and has graduation lines 11, so it can be used directly as the bottle body 1.

[0047] like Figure 1 As shown, the bottle cap 2 is located at the open end of the bottle body 1 to seal the open end of the bottle body 1. In order to facilitate the removal of the bottle cap 2 to add water into the bottle body 1, in this embodiment, the bottle cap 2 is detachably connected to the open end of the bottle body 1. Specifically:

[0048] Combination Figure 4 As shown, the outer peripheral wall of the open end of the bottle body 1 is provided with an external thread section 12; the inner peripheral wall of the bottle cap 2 is provided with an internal thread section 22 that is adapted to the external thread section 12; the bottle cap 2 is threadedly connected to the external thread section 12 of the bottle body 1 through the internal thread section 22.

[0049] Of course, in order to improve the sealing performance of the connection between the bottle cap 2 and the bottle body 1, a sealing ring 23 is provided inside the bottle cap 2. Specifically, the sealing ring 23 can be a frameless rubber ring, so that its outer wall is tightly fitted with the inner wall of the bottle body 1 to strengthen the seal and prevent water leakage.

[0050] It is worth mentioning that since existing centrifuge tubes are generally equipped with caps (the caps are threaded onto the open end of the centrifuge tube), the caps of the centrifuge tubes mentioned above can be directly used as bottle caps 2.

[0051] like Figure 1 As shown, the pressure stabilizer 3 is located on the closed end side wall of the bottle body 1, and the interior of the pressure stabilizer 3 is hollow to form an air flow channel for air circulation (not shown in the figure due to perspective). The air flow channel is straight and connects the interior of the bottle body 1 with the outside air through the air flow channel. Specifically, one end of the air flow channel is connected to the interior of the bottle body 1, and the other end is located outside the bottle body 1 and connected to the outside environment. Air is supplied to the interior of the bottle body 1 through the air flow channel to balance the air pressure inside the bottle body 1.

[0052] It is worth mentioning that the diameter of the air channel in the pressure stabilizer 3 is in the range of 0.35mm-0.6mm. The diameter here is the opening diameter of the air channel. If the diameter of the air channel is too large or too small, it will affect the water output effect of the water outlet 4.

[0053] As a preferred implementation, the diameter of the airflow channel is 0.45 mm.

[0054] In this embodiment, the pressure stabilizer 3 can be a standard 1ml syringe needle. In other words, the standard 1ml syringe needle can be used as the pressure stabilizer 3. In this way, the injection channel inside the needle can be used as the air flow channel in this embodiment. Because the injection channel of the needle is small, it can be used as an air flow channel connecting the inside of the bottle 1 with the external air pressure. It is easy to obtain materials and has low cost.

[0055] Furthermore, since the tip of the syringe needle is needle-shaped, when assembling the needle onto the bottle body 1, a blind hole can be drilled on the outer wall of the bottle body 1 (i.e., the hole does not directly penetrate the bottle wall of the bottle body 1). The blind hole is mainly used to reduce the wall thickness of the bottle body 1. Then, the tip of the needle can be directly pierced through the bottle wall at the location of the blind hole. At this time, the needle is inserted into the bottle body 1. Since the needle directly pierces the bottle body 1, the connection point between the needle and the bottle body 1 (i.e., the piercing point) fits very tightly with almost no gaps, resulting in a high degree of sealing. Thus, no additional sealing treatment is required at the connection point.

[0056] The water outlet 4 is installed on the bottle cap 2. Its interior is hollow, forming a water outlet channel for water to flow through (not shown in the figure due to perspective). The water is mainly discharged from the bottle body 1 through this water outlet channel for animals to drink. It is worth mentioning that the water outlet channel is straight, and water enters at one end, i.e., the inlet end, and water exits at the other end, i.e., the outlet end. The diameter of the outlet end is in the range of 0.4mm-1.0mm, where the diameter refers to the opening diameter of the outlet end.

[0057] As a preferred embodiment, the diameter of the water outlet end of the water outlet channel is 0.6mm.

[0058] Since the diameter of the water outlet end of the water outlet channel is small (0.4mm-1.0mm), under the water tension, water will be blocked in the water outlet channel of the water outlet member 4 and will not naturally drip, without the device being touched by external force. When the device is touched by external force, such as when an animal touches the device, the device will shake, and thus the water tension in the water outlet channel of the water outlet member 4 will be destroyed, and the water will be discharged from the water outlet end of the water outlet member 4. When the touching stops, the water tension in the water outlet member 4 is restored, and under the water tension, the water will be blocked in the water outlet member 4 again, and thus the water will not drip, thereby achieving the effect of automatic water stop.

[0059] It is worth mentioning that if the diameter of the water outlet end of the water outlet channel of the water outlet member 4 is too large, the effect of automatic water stop cannot be achieved, i.e. water will continuously be discharged from the water outlet member 4. If the diameter of the water outlet end of the water outlet channel is too small, even if the device is touched, the water outlet member 4 will be difficult to drip water.

[0060] Specifically, in the present embodiment, the tip of an existing 100μl-1000μl plastic material pipette can be used as the water outlet member 4. The outer wall of the tip of the existing pipette is in the shape of a cone, and the channel inside the tip can be used as the water outlet channel. Moreover, the diameter of the liquid outlet port of the tip is small, and thus the tip can be used as the water outlet member 4 in the present embodiment.

[0061] Moreover, the outer wall of the tip of the existing pipette is in the shape of a cone, i.e. the tip gradually narrows towards the water outlet end of the tip along the axial direction. Thus, when the tip is assembled to the bottle cap 2, only a small through hole 21 (penetrating the bottle cap 2) needs to be formed on the bottle cap 2. The radius of the through hole 21 is smaller than the diameter of the tail end section of the tip (i.e. the section far from the liquid outlet end of the tip). Thus, when the tip is installed, the water outlet end of the tip is inserted into the through hole 21 from the inner side of the bottle cap 2, and the tip is continuously pushed. When the tail end section of the tip is inserted into the position of the through hole 21, since the diameter of the through hole 21 is smaller than the diameter of the section, the tip can be stably and tightly embedded in the through hole 21. At this time, there is almost no gap between the outer wall of the tip and the hole wall of the through hole 21, which ensures the sealing property, and the problem of water seepage from the edge of the through hole 21 does not occur.

[0062] Principle: when using the device, first unscrew the bottle cap 2, inject an appropriate amount of water into the bottle body 1, then screw the bottle cap 2, place the entire device on the water feeding carrier of the animal cage (such as a mouse cage), at this time ensure that one end of the water outlet 4 faces the inside of the cage for the animal to touch and suck; in this way, when the animal touches the device or sucks, the water tension at the water outlet of the water outlet 4 is broken, the water outlet end of the water outlet channel of the water outlet 4 starts to supply water for the animal to drink, when the touching or sucking stops, the water in the water outlet 4 is again blocked under the water tension, and cannot continue to supply water, achieving the effect of automatic water stop. As can be seen, the automatic water supply feeding function can be realized.

[0063] Moreover, as can be known from the above description, the materials in the present application are all composed of conventional basic consumables in the laboratory, which are convenient to obtain and easy to assemble. Moreover, these consumables are low in cost, so that the manufacturing cost of the device is low, and therefore the device can be used as a disposable drinking water device.

[0064] Example 2:

[0065] The present embodiment provides an assembly method of a rodent experimental animal feeding and drinking device, comprising the following steps:

[0066] S1, prepare the following materials:

[0067] - bottle body 1, one end of which is open and the other end is closed, specifically, an existing 50ml plastic centrifuge tube can be used as the bottle body 1, as shown in Figure 1 .

[0068] - bottle cap 2, which is matched with the open end of the bottle body 1, used to be installed on the open end of the bottle body 1 to block the open end of the bottle body 1, specifically, the cap of the above-mentioned centrifuge tube is used as the bottle cap 2, as shown in Figure 3 and Figure 4 .

[0069] - water outlet 4, which is hollow inside to form a water outlet channel, one end of the water outlet channel is water inlet, i.e. the water inlet end, the other end is water outlet, i.e. the water outlet end, and the diameter of the water outlet end is in the range of 0.4mm-1.0mm; specifically, an existing 100ul-1000ul plastic pipette tip is used as the water outlet 4, as shown in Figure 1 .

[0070] - pressure stabilizing piece 3, which is hollow inside to form an air flow channel, and the diameter of the air flow channel is in the range of 0.35mm-0.6mm; an existing 1ml standard syringe needle is used as the pressure stabilizing piece 3, as shown in Figure 1 .

[0071] S2, assemble the pressure stabilizer 3 (i.e. the syringe needle): install the pressure stabilizer 3 on the closed end side wall of the bottle body 1, so that one end of the pressure stabilizer 3 is in communication with the inside of the bottle body 1 and the other end is in communication with the outside environment. The specific steps are as follows: use a tool such as scissors to drill a blind hole (i.e. the hole does not penetrate the bottle wall of the bottle body 1) on the side wall of the closed end of the bottle body 1. The purpose of drilling the blind hole is to thin the bottle wall of the bottle body 1 to ensure that the syringe needle can be quickly and conveniently inserted into the bottle body 1 by piercing the bottle wall.

[0072] Next, the tip of the syringe needle is aligned with the blind hole, and the tip of the syringe needle is used to pierce the inner hole wall of the blind hole until the tip of the syringe needle extends into the bottle body 1 and communicates with the bottle body 1. Since the needle is directly inserted into the bottle body 1 by piercing the bottle wall, the cooperation between the needle and the bottle body 1 is very tight at this time, with good sealing performance, and no additional sealing treatment is required.

[0073] S3, assemble the water outlet 4 (i.e. the pipette head): install the water outlet 4 on the bottle cap 2 so that the two ends of the water outlet 4 are located on the two sides of the bottle cap 2; wherein the specific steps for assembling the water outlet 4 are as follows: use a tool such as scissors to drill a through hole 21 (as shown in Figure 3 ) on the bottle cap 2 for inserting the head; wherein the diameter of the through hole 21 is smaller than the diameter of the tail end section of the head. It is pointed out that the outer wall of the existing pipette head is conical.

[0074] Then the head end of the head is inserted into the through hole 21 from the inside of the bottle cap 2 until the tail end section of the head is clamped in the through hole 21. In this way, when installing the head, only the water outlet end of the head needs to be inserted into the through hole 21 from the inside of the bottle cap 2, and the head is continuously pushed. When the tail end section of the head reaches the position of the through hole 21, since the diameter of the through hole 21 is smaller than the diameter of the section, the head can be stably and tightly embedded in the through hole 21, so that the head is not easy to fall off. At this time, there is almost no gap between the outer wall of the head and the hole wall of the through hole 21, ensuring its sealing performance, and there is no problem of water seepage at the edge of the through hole 21.

[0075] S4, assemble the bottle cap 2, first pad the sealing ring 23 in the bottle cap 2, then rotate and tighten the bottle cap 2 on the open end of the bottle body 1, so that the water inlet end of the water outlet flow channel in the water outlet 4 on the bottle cap 2 is in communication with the inside of the bottle body 1, and the water outlet end of the water outlet flow channel is located outside the bottle body 1 and in communication with the outside environment, to guide the water for the animals to drink.

[0076] Complete the assembly of the entire device.

[0077] From the above assembly method, it can be seen that the materials used by the device are basically conventional consumables in the laboratory, which are easy to obtain, and during assembly, many tools are not needed to assist, so that the assembly of the device can be quickly and conveniently completed. Moreover, the cost of these consumables is low, so the device can be used at one time or repeatedly used for a long time.

[0078] The above is only a typical example of the present application, in addition to which the present application can have other various specific embodiments, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
