Detailed Description
The following detailed description of the invention is provided in connection with the accompanying drawings to facilitate understanding and grasping of the technical scheme of the invention.
Example 1:
As shown in fig. 1, the embodiment provides a rodent feeding and drinking device, which comprises a bottle body 1, a bottle cap 2, a water outlet piece 4 and a pressure stabilizing piece 3. Specific:
The bottle body 1 has one open end and the other closed end, is mainly used for containing animal drinking water, and is used for conveniently and intuitively observing the actual water containing amount in the bottle body 1, in the embodiment, the bottle body 1 is made of transparent materials, and the bottle body 1 is provided with scale marks 11 distributed along the axial direction of the bottle body 1; the water quantity in the bottle body 1 can be directly read out by the scale marks 11.
As shown in fig. 1 and 2, the bottle 1 may be a centrifuge tube made of 50ml of plastic material, which is currently available in the laboratory, and the centrifuge tube is mainly made of transparent plastic material and has graduation marks 11, so that the bottle 1 can be directly used.
As shown in fig. 1, the bottle cap 2 is disposed at an open end of the bottle body 1 to close the open end of the bottle body 1, and for conveniently taking down 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:
Referring to fig. 4, an external thread section 12 is provided on the outer peripheral wall of the open end of the bottle body 1; an inner thread section 22 matched with the outer thread section 12 is arranged on the inner peripheral wall of the bottle cap 2; the bottle cap 2 is in threaded connection with the external thread section 12 of the bottle body 1 through the internal thread section 22.
Of course, in order to improve the connection tightness between the bottle cap 2 and the bottle body 1, a sealing ring 23 is arranged in the bottle cap 2, wherein the sealing ring 23 can be 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, and the sealing ring is used for strengthening sealing and avoiding water infiltration.
It should be noted that, since the conventional centrifuge tube is generally provided with a tube cap (the tube cap is screwed on the open end of the centrifuge tube), the tube cap of the centrifuge tube can be directly used as the bottle cap 2.
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 an air flow channel (not shown in view reason diagram) for air circulation is formed in the pressure stabilizer 3 in a hollow manner, and the air flow channel is in a straight line shape, so that the interior of the bottle body 1 is communicated with the outside air through the air flow channel, specifically: one end of the air flow passage is communicated with the interior of the bottle body 1, the other end of the air flow passage is arranged outside the bottle body 1 and communicated with the external environment, and air is supplemented into the bottle body 1 through the air flow passage 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 stabilizing member 3 ranges from 0.35mm to 0.6mm, and the diameter of the air flow passage is the caliber of the air flow passage, and the excessive or insufficient diameter of the air flow passage can affect the water outlet effect of the water outlet member 4.
As a preferred embodiment, the diameter of the air flow channel is 0.45mm.
In this embodiment, the pressure stabilizer 3 may be an existing 1ml standard syringe needle, in other words, an existing 1ml standard syringe needle is used as the pressure stabilizer 3, so that 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 smaller, the needle can be used as an air flow channel for communicating the interior of the bottle body 1 with the outside air pressure, and the material is convenient to obtain and the cost is low.
Moreover, because the head end (needle tip) of the syringe needle is pointed, when the needle is assembled on the bottle body 1, a blind hole (i.e. 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 formed for reducing the wall thickness of the bottle body 1, then the tip of the needle can directly penetrate through the wall of the position where the blind hole is located, at the moment, the needle is inserted on the bottle body 1, and because the needle directly penetrates through the bottle body 1, the connection position (i.e. the penetrating position) of the needle and the bottle body 1 is very tightly matched, almost has no gap, can have higher tightness, and does not need to do extra sealing treatment at the connection position.
The water outlet member 4 is mounted on the bottle cap 2, and a water outlet flow passage (not shown in view angle reason chart) through which water flows is formed in the interior of the bottle cap, and water in the bottle body 1 is led out mainly through the water outlet flow passage for animals to drink, it is worth mentioning that the water outlet flow passage is in a straight line shape, one end of the water outlet flow passage is provided with water inlet, namely a water inlet end, and the other end of the water outlet flow passage is provided with water outlet, namely a water outlet end, wherein the diameter of the water outlet end ranges from 0.4mm to 1.0mm, and the diameter refers to the caliber of the water outlet end.
As a preferred embodiment, the diameter of the water outlet end of the water outlet channel is 0.6mm.
Because the diameter of the water outlet end of the water outlet flow channel is smaller (0.4 mm-1.0 mm), the whole device is not touched by external force, water can be blocked in the water outlet flow channel of the water outlet piece 4 under the tension of water and can not naturally drop, when the device is touched by external force, such as an animal touching device, the device can shake, the tension of the water in the water outlet flow channel of the water outlet piece 4 is destroyed, the balance is lost, the water can be discharged from the water outlet end of the water outlet piece 4, when touching is stopped, the tension of the water in the water outlet piece 4 is restored, the water is blocked in the water outlet piece 4 again under the tension, and the water can not drop, so the effect of automatic water stopping is realized.
It should be noted 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 cut-off cannot be achieved, that is, water is continuously discharged from the water outlet member 4, and 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 is difficult to drip water.
Specifically, in this embodiment, the tip of the existing 100 μl-1000 μl plastic pipette may be used as the water outlet member 4, the outer wall of the existing pipette tip is cone-shaped, the internal channel of the existing pipette tip can be used as the water outlet flow channel, and the caliber of the liquid outlet end of the tip is smaller, so that the existing pipette tip can be used as the water outlet member 4 in this embodiment.
The outer wall of the existing pipetting gun head is conical, namely the gun head gradually narrows towards one side of the water outlet end of the gun head along the axial direction of the gun head; thus, when the gun head is assembled on the bottle cap 2, only a small through hole 21 (penetrating through the bottle cap 2) is needed to be formed on the bottle cap 2; the radius of the through hole 21 is smaller than that of the tail end section of the gun head (namely, one end far away from the liquid outlet end of the gun head), so that when the gun head is installed, the water outlet end of the gun head only needs to penetrate into the through hole 21 from the inner side of the bottle cap 2, and the gun head is continuously pushed, when the tail end section of the gun head penetrates to the position of the through hole 21, the gun head can be firmly and tightly embedded in the through hole 21 due to the fact that the diameter of the through hole 21 is smaller than that of the section, no gap is almost reserved between the outer wall of the gun head and the hole wall of the through hole 21, the sealing performance of the gun head is guaranteed, and the problem of water seepage at the edge of the through hole 21 can not occur.
The implementation principle is as follows: when the device is used, the bottle cap 2 is unscrewed, a proper amount of water is injected into the bottle body 1, then the bottle cap 2 is screwed, the whole device is placed on a water feeding carrier of an animal cage (such as a squirrel cage), and at the moment, one end of the water outlet piece 4 faces the inside of the cage to be sucked by animals; when an animal touches the device or sucks, the tension of water at the water outlet of the water outlet piece 4 is destroyed, the water outlet end of the water outlet flow channel of the water outlet piece 4 starts to output water for the animal to drink, and when the animal touches or sucks to stop, the water in the water outlet piece 4 is plugged again under the tension of the water, the water cannot be continuously discharged, the effect of automatic water cut-off is realized, and therefore, the function of automatic water supply feeding can be realized.
Moreover, as can be seen from the description, the materials in the invention are composed of conventional basic consumables in a laboratory, and the materials are convenient to obtain and assemble. And the consumable materials have low cost, so that the device has lower manufacturing cost and can be used as a disposable drinking water device.
