Description

Technical Field

[0001] The utility model relates to the technical field of medical experiments, in particular to a leakage-proof water feeding device. Background Art

[0002] Laboratory animals are animals specially bred for experimental use. They mainly refer to animals that are domesticated, bred, and raised for the purpose of scientific research, teaching, medical treatment, identification, diagnosis, and biological product manufacturing in medicine, pharmacy, biology, and veterinary medicine. For example, mice and rats are experimental animals that are first bred strictly according to experimental requirements. In the past, the main way to feed water to experimental animals was to use a milk bottle-type water bottle. This type of water bottle is generally composed of a bottle body, a bottle stopper, and a straw. It has the advantages of being economical, easy to move, and easy for animals to drink water. They are described as follows: (1) Economical. Compared with the unified water supply in the animal room, the water bottle does not require engineering modification, has no special requirements for the environment, and is economical. (2) Convenient. The water bottle can be moved with the animal or the animal cage, which is convenient for feeding the animal when changing locations or waiting for a long time. (3) Effortless for animals to drink water. Animals obtain water by licking the straw of the water bottle. During this process, air enters the bottle through the straw, making the air pressure above the liquid in the bottle equal to the atmospheric pressure. This makes it easy for the ordinary water bottle straw to dispense water, and animals do not need special training to drink. (4) It is convenient to provide customized water for specific experimental animal populations. The water bottle can be said to be one of the most common water supply systems for experimental animals.

[0003] However, when the water bottle is placed in the breeding cage, after the licking action stops, the water bottle needs to continue dripping water for a while. When the water source in the bottle decreases, the space in the bottle increases, and the air pressure in the bottle is slightly lower than the atmospheric pressure, the dripping action will automatically stop, and the automatic water stop of the water bottle will be realized. This is a simple self-correction process to prevent water leakage and maintain negative pressure. But in fact, when the animal's intense activities (such as fighting, experimental intervention causing irritability and other behavioral changes) cause the cage to collide, the water bottle will continue to drip due to shaking. During the shaking process, dripping water can easily cause small air bubbles to enter the bottle, causing the water bottle to be unable to maintain negative pressure and continue to drip water. The more the cage shakes, the more water drops will be thrown away from the licking end of the water bottle straw, and the easier it is for air to enter the bottle. In other words, when the bottle shakes, it is easy to enter a vicious cycle of "dripping water-intake air-dripping water-intake air", causing the water bottle to leak. When the water bottle leaks, it will have a variety of adverse consequences, affecting the health of experimental animals and the progress of the experiment. First, the amount of water animals drink is not accurately measured, affecting experimental records. Second, a large amount of bedding is accidentally soaked, increasing the chances of animal illness and even causing mice to drown. In addition, animals such as diabetic models lack sufficient drinking water and it is difficult to predict the timing of water replenishment, increasing the difficulty of feeding. Third, it will cause animals to have "empty bottle anxiety", adding variables that affect experimental results.

[0004] Therefore, it is necessary to provide a leak-proof water feeding device that can prevent shaking and cause water leakage. Utility Model Content

[0005] The utility model aims to provide a leakage-proof water feeding device which can prevent water leakage caused by shaking.

[0006] To achieve the above purpose, the utility model provides a leakage-proof water feeding device, comprising:

[0007] The bottle body is provided with a partition, which divides the bottle body into a water storage section and a water outlet section. The partition is provided with a water through hole, through which the water storage section is connected to the water outlet section;

[0008] The anti-leakage water outlet assembly includes a gravity member and a buoyancy member, wherein the density of the gravity member is greater than the density of the liquid in the bottle body, and the density of the buoyancy member is less than the density of the liquid in the bottle body, and the gravity member always has a tendency to sink downward, and the buoyancy member always has a tendency to float upward; the gravity member is located in the water storage section, and the buoyancy member is located in the water outlet section, and a connecting line is provided between the gravity member and the buoyancy member;

[0009] Among them, the gravity piece is spherical and has multiple water outlet channels running through it, and the buoyancy piece is a spherical structure; one side of the gravity piece passes through the water hole in a static state, so that there is a water outlet gap between the buoyancy piece and the water hole; the bottle body is shaken to make the gravity piece roll along the partition and drive the buoyancy piece to block the water hole.

[0010] Compared with the prior art, the leak-proof water feeding device of the utility model can effectively prevent the device from leaking due to shaking. The leak-proof water feeding device includes a bottle body and a leak-proof water outlet assembly, and the leak-proof water outlet assembly includes a gravity member, a buoyancy member, and a connecting line for connecting the gravity member and the buoyancy member. A partition is provided in the bottle body, the gravity member is located on one side of the partition, and the buoyancy member is located on the other side of the partition. Specifically, the partition divides the bottle body into a water storage section and a water outlet section, the gravity member is located in the water storage section, and the buoyancy member is located in the water outlet section. A water hole is provided on the partition so that the water storage section is connected to the water outlet section, and the water in the water storage section can enter the water outlet section through the water hole. Since the density of the gravity member is greater than the density of the liquid in the bottle, and the density of the buoyancy member is less than the density of the liquid in the bottle. The gravity member always has a tendency to sink downward, and the buoyancy member always has a tendency to float upward. Among them, the gravity piece is spherical and has multiple water outlet channels running through it along its circumference. In a static state, the gravity piece sinks downward under the action of its own gravity and one end passes through the water hole on the partition to prevent the buoyancy piece floating upward from blocking the water hole. The buoyancy piece floats upward and presses against the partition or the gravity piece. Since multiple water outlet channels are provided on the gravity piece, the water in the water storage section can enter the water outlet section. On the other hand, when the bottle body shakes, the gravity piece rolls along the partition and detaches from the water hole under the shaking, and at the same time, the buoyancy piece is pulled by the connecting piece, and the buoyancy piece always has an upward tendency and blocks the water hole. The leak-proof water feeding device of the utility model has a simple structure and can effectively prevent the device from leaking due to shaking.

[0011] Preferably, the diameter of the water hole is smaller than the ball diameter of the gravity member.

[0012] Preferably, the thickness of the portion of the gravity member passing through the water hole is greater than the thickness of the partition, so that the portion of the gravity member passing through the water hole can be located in the water outlet section in a static state.

[0013] Preferably, one end of the connecting line is connected to the gravity member, and the other end of the connecting line is connected to the buoyancy member, and the length of the connecting line between the gravity member and the buoyancy member is less than the spherical radius of the gravity member.

[0029] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0030] See also Figure 1 and Figure 2The utility model provides a leak-proof water feeding device 100, comprising a bottle body 10 and a leak-proof water outlet assembly 20. A partition 11 is arranged in the bottle body 10, and the partition 11 divides the space in the bottle body 10 into a water storage section 101 and a water outlet section 102. A water through hole 111 is opened on the partition 11, and the water storage section 101 is connected to the water outlet section 102 through the water through hole 111. The leak-proof water outlet assembly 20 includes a gravity member 21 and a buoyancy member 22, and the density of the gravity member 21 is greater than the density of the liquid in the bottle body 10, so that the gravity member 21 always has a tendency to sink downward. The density of the buoyancy member 22 is less than the density of the liquid in the bottle body 10, so that the buoyancy member 22 always has a tendency to float upward. Specifically, the gravity member 21 is located in the water storage section 101, the buoyancy member 22 is located in the water outlet section 102, and a connecting line 23 is arranged between the gravity member 21 and the buoyancy member 22. The gravity member 21 is spherical, and a plurality of water outlet channels 211 are provided through the gravity member 21. The buoyancy member 22 is also spherical. In a static state, one side of the gravity member 21 passes through the water hole 111, and the portion passing through the water hole 111 is located in the water outlet section 102, so that there is a water outlet gap between the buoyancy member 22 and the water hole 111, that is, the gravity member 21 passes through the water hole 111 to prevent the buoyancy member 22 from blocking the water hole 111, so that the liquid in the water storage section 101 can reach the water outlet section 102 through the water outlet channel 211 on the gravity member 21. When the bottle body 10 is shaken, the gravity member 21 rolls along the partition 11 and then returns from the water outlet section 102 to the water storage section 101. At the same time, the gravity member 21 drives the buoyancy member 22 to move through the connecting line 23, and the gravity member 21 is separated from the water hole 111 so that the buoyancy member 22 can be blocked at the water hole 111.

[0031] Compared with the prior art, the leak-proof water feeding device 100 of the utility model can effectively prevent water leakage due to shaking. The leak-proof water feeding device 100 includes a bottle body 10 and a leak-proof water outlet assembly 20, and the leak-proof water outlet assembly 20 includes a gravity member 21, a buoyancy member 22, and a connecting line 23 for connecting the gravity member 21 and the buoyancy member 22. A partition 11 is arranged in the bottle body 10, the gravity member 21 is located on one side of the partition 11, and the buoyancy member 22 is located on the other side of the partition 11. Specifically, the partition 11 divides the bottle body 10 into a water storage section 101 and a water outlet section 102, the gravity member 21 is located in the water storage section 101, and the buoyancy member 22 is located in the water outlet section 102. A water through hole 111 is opened on the partition 11 to connect the water storage section 101 to the water outlet section 102, so that the water in the water storage section 101 can enter the water outlet section 102 through the water through hole 111. Since the density of the gravity member 21 is greater than the density of the liquid in the bottle, and the density of the buoyancy member 22 is less than the density of the liquid in the bottle, the gravity member 21 always tends to sink downward, and the buoyancy member 22 always tends to float upward. The gravity member 21 is spherical and has a plurality of water outlet channels 211 running through it along its circumference. In a static state, the gravity member 21 sinks downward under its own gravity and one end passes through the water hole 111 on the partition 11 to prevent the buoyancy member 22 floating upward from blocking the water hole 111. The buoyancy member 22 floats upward and presses against the partition 11 or the gravity member 21. Since a plurality of water outlet channels 211 are provided on the gravity member 21, the water in the water storage section 101 can enter the water outlet section 102. On the other hand, when the bottle body 10 is shaken, the gravity member 21 rolls along the partition 11 and detaches from the water hole 111, and at the same time pulls the buoyancy member 22 through the connecting member, and the buoyancy member 22 always has an upward tendency and blocks the water hole 111. The leak-proof water feeding device 100 of the utility model has a simple structure and can effectively prevent the device from leaking due to shaking.

[0032] See also Figures 1 to 4In some optional embodiments, the diameter of the water hole 111 is smaller than the ball diameter of the gravity member 21. It is understandable that the ball diameter of the gravity member 21 is larger than the water hole 111 so that the gravity member 21 can always remain in the water storage section 101. On the other hand, the thickness of the portion of the gravity member 21 that passes through the water hole 111 is greater than the thickness of the partition 11, so that the gravity member 21 can pass through the portion of the water hole 111 and be located in the water outlet section 102 in a static state. The thickness of the partition 11 should not be too thick so that a portion of the gravity member 21 can pass through the water hole 111 and be located in the water outlet section 102, thereby ensuring that the water in the water storage section 101 can flow into the water outlet section 102 normally, and water can be discharged normally when the experimental animals need to drink water. In addition, the ball diameter of the buoyancy member 22 is larger than the radius of the water hole 111 so that the buoyancy member 22 is always placed in the water outlet section 102. The ball diameter of the buoyancy member 22 is larger than the water hole 111, so that the buoyancy member 22 can always remain in the water outlet section 102. When the weight member 21 is shaken away from the water hole 111, the buoyancy member 22 can be pulled and blocked at the water hole 111, so that the water in the water storage section 101 will not continue to enter the water outlet section 102.

[0033] See also Figure 1 , Figure 2 and Figure 4 In some optional embodiments, one end of the connecting line 23 is connected to the gravity member 21, and the other end of the connecting line 23 is connected to the buoyancy member 22, and the length of the connecting line 23 between the gravity member 21 and the buoyancy member 22 is less than the spherical radius of the gravity member 21. It can be understood that if the length of the connecting line 23 between the gravity member 21 and the buoyancy member 22 is too long, the buoyancy member 22 cannot be pulled to the water hole 111 in time when the gravity member 21 shakes, thereby failing to effectively achieve the purpose of preventing water leakage. Therefore, the connecting line 23 must be of a suitable length. Among them, a connecting portion 212 connected to the connecting line 23 is provided on the gravity member 21, and a fixing portion 221 for fixing the connecting line 23 is provided on the buoyancy member 22. Through the connecting portion 212 and the fixing portion 221, the connecting line 23 is firmly connected to the gravity member 21 and the buoyancy member 22. Thereby, the gravity member 21 can drive the buoyancy member 22 to move, so that the buoyancy member 22 can block the water hole 111 .

[0034] See also Figures 1 to 3In some optional embodiments, the water outlet section 102 is provided with a water outlet 121, and a water feeding pipe 13 is connected to the water outlet 121, and one end of the water feeding pipe 13 is tilted at a preset angle. It can be understood that an opening is provided at one end of the water outlet section 102 away from the water storage section 101, so that water can be replenished after the water in the bottle body 10 is used up. A cover body 12 is provided at the opening, and the cover body 12 is used to block the opening. A water outlet 121 is provided on the cover body 12, and a water feeding pipe 13 is connected to the water outlet 121, and the water feeding pipe 13 is used for animals to lick and replenish water. One end of the water feeding pipe 13 is set to a structure with a certain tilt angle, which can facilitate animal licking, and the structure is reasonably set. The preset angle can be a reasonable water feeding angle such as 15°, 30° or 45°.

[0035] See also Figures 1 to 3 In some optional embodiments, the partition 11 is close to the water outlet 121 so that the volume of the water storage section 101 is larger than the volume of the water outlet section 102, and the height of the water outlet section 102 is larger than the ball diameter of the buoyancy member 22. Among them, the bottle body 10 has a gradual structure from the water storage section 101 to the water outlet section 102, with a cross-sectional area gradually decreasing. The volume of the water storage section 101 is much larger than the volume of the water outlet section 102, but the water outlet section 102 can still make the buoyancy member 22 float.

[0036] See also Figures 1 to 3 In some optional embodiments, the partition 11 is an arc-shaped plate and is integrally formed with the bottle body 10, and the concave surface of the partition 11 is located in the water storage section 101, and the convex surface of the partition 11 is located in the water outlet section 102. Among them, the concave surface of the partition 11 is smoothly arranged so that the gravity member 21 rolls along the partition 11. It can be understood that the partition 11 is an arc-shaped structure, and the water hole 111 is opened in the middle of the partition 11, that is, the water hole 111 is located at the lowest point of the partition 11, and the gravity member 21 is a spherical structure. The gravity member 21 can automatically roll to the lowest point under the action of its own gravity. Thereby, the gravity member 21 can be located at the water hole 111 in a static state, and a part of it passes through the water hole 111. The gravity member 21 is hollowed out so that the water in the water storage section 101 can be thrown through the gravity member 21 into the water outlet section 102. On the other hand, the plane where the buoyancy member 22 is located is the convex surface of the partition 11. In a static state, the buoyancy member 22 has the characteristic of floating upward and floats away from the water hole 111. However, under the traction of the connecting line 23, the buoyancy member 22 will not move away from the water hole 111, and the buoyancy member 22 is against the partition 11 and the gravity member 21. Exemplarily, the gravity member 21 can be a rust-proof hollow metal ball, and the buoyancy member 22 can be a buoyant ball. In some embodiments, the gravity member 21 is a loose hollow sphere woven from non-dense filamentary materials. Specifically, the gravity member 21 can be woven from metal wire, or the gravity member 21 can be woven from materials such as rattan, so that the overall gap is larger, so that water can pass through the gravity member 21 better.

[0037] like Figures 1 to 4 As shown, the leak-proof water feeding device 100 of the utility model can effectively prevent water leakage due to shaking. The leak-proof water feeding device 100 includes a bottle body 10 and a leak-proof water outlet assembly 20, and the leak-proof water outlet assembly 20 includes a gravity member 21, a buoyancy member 22, and a connecting line 23 for connecting the gravity member 21 and the buoyancy member 22. A partition 11 is arranged in the bottle body 10, the gravity member 21 is located on one side of the partition 11, and the buoyancy member 22 is located on the other side of the partition 11. Specifically, the partition 11 divides the bottle body 10 into a water storage section 101 and a water outlet section 102, the gravity member 21 is located in the water storage section 101, and the buoyancy member 22 is located in the water outlet section 102. The partition 11 is an arc-shaped structure, and a water hole 111 is provided on the partition 11, so that the water storage section 101 is connected to the water outlet section 102, so that the water in the water storage section 101 can enter the water outlet section 102 through the water hole 111. Since the density of the gravity member 21 is greater than the density of the liquid in the bottle, and the density of the buoyancy member 22 is less than the density of the liquid in the bottle, the gravity member 21 always has a tendency to sink downward, and the buoyancy member 22 always has a tendency to float upward. Among them, the gravity member 21 is spherical and has a plurality of water outlet channels 211 running through it along its circumference. In a static state, the gravity member 21 rolls along the partition 11 to the lowest point under the action of its own gravity, and one end passes through the water hole 111 on the partition 11, so as to prevent the buoyancy member 22 floating upward from blocking the water hole 111. The buoyancy member 22 floats upward and presses against the partition 11 or the gravity member 21. Since a plurality of water outlet channels 211 are provided on the gravity member 21, the water in the water storage section 101 can enter the water outlet section 102. On the other hand, when the bottle body 10 is shaken, the gravity member 21 rolls along the partition 11 and detaches from the water through hole 111, and at the same time pulls the buoyancy member 22 through the connecting member, and the buoyancy member 22 always has an upward trend and blocks the water through hole 111. The greater the shaking amplitude of the bottle body 10, the more the gravity member 21 rolls, and the more the buoyancy member 22 is blocked at the water through hole 111 under the pull of the gravity member 21, and the better the waterproof effect. When stationary, the gravity member 21 rolls to the lowest point under the action of its own gravity, and the connecting line 23 between the gravity member 21 and the buoyancy member 22 is loose, and the buoyancy member 22 floats to the high buoyancy point. At the same time, the gravity member 21 can also push the buoyancy member 22 away from the water hole 111, so that the water in the water storage section 101 can enter the water outlet section 102 through the water outlet channel 211 on the gravity member 21, and the water feeding pipe 13 can discharge water normally. The leak-proof water feeding device 100 of the utility model has a simple structure, can effectively prevent the device from leaking due to shaking, and will not affect the original advantage of the milk bottle type water feeding bottle of convenient water acquisition.
