Description

Technical Field

[0001] This invention relates to the field of drinking bag technology, specifically a disposable animal drinking bag. Background Technology

[0002] A novel disposable animal drinking bag, disclosed in publication number CN113841626A, includes a valve and a bag body. The valve is installed at one end of the bag body and includes a valve nozzle, a knob, a valve stem, an elastic element, and a sealing ring. One end of the valve stem passes through the valve nozzle and extends to the outside of the nozzle, while the other end of the valve stem has a groove. A sealing ring is provided between the valve stem and the valve nozzle. An elastic element is disposed inside the valve nozzle, with one end of the valve nozzle fixed to one end of the knob. The knob has a through hole at one end of the elastic element. Both ends of the elastic element abut against the valve stem and the knob, and the elastic element is designed as a hollow structure. This technology isolates the liquid inside the bag from the atmosphere, preventing contamination and eliminating the need for regular cleaning and sterilization. It is disposable, convenient, quick, and time-saving.

[0003] Existing technologies seal valve stems and valve nozzles by using a combination of valve stem and sealing ring; this increases the number of parts and results in relatively poor sealing performance between the sealing ring and valve stem. Therefore, we propose a disposable animal drinking bag. Summary of the Invention

[0004] The purpose of this invention is to provide a disposable animal drinking bag to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disposable animal drinking bag, comprising a bag body and a valve, wherein the valve comprises a valve nozzle, an elastic element, a valve stem, and an annular sleeve; the elastic element is disposed inside the valve nozzle, and an annular sleeve is installed at the end of the valve nozzle away from the bag body, and a valve stem is installed at the annular sleeve, with one end of the valve stem abutting against the elastic element; the valve stem comprises a valve stem seat, a frustum, and a rod body, wherein a groove is formed at one end of the valve stem seat, a frustum is disposed at the other end of the valve stem seat, and a rod body is disposed at the end of the frustum away from the valve stem seat.

[0006] Preferably, the diameter of the truncated cone at one end of the valve stem seat is larger than the inner diameter of the annular sleeve, and the diameter of the truncated cone at the end away from the valve stem seat is smaller than the inner diameter of the annular sleeve.

[0007] Preferably, the outer side of the annular sleeve is provided with at least one annular protrusion, and the inner wall of the valve nozzle is provided with an annular groove that mates with the annular protrusion.

[0008] Preferably, the valve stem seat has a column on the side of the elastic element.

[0009] Preferably, it also includes a stainless steel cylinder, which is sleeved on the outside of the valve nozzle.

[0010] Preferably, the valve nozzle is provided with an annular piece at one end of the bag body.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. A frustum is provided at the other end of the valve stem seat; the diameter of the frustum at one end of the valve stem seat is larger than the inner diameter of the annular sleeve, and the diameter of the end of the frustum away from the valve stem seat is smaller than the inner diameter of the annular sleeve; sealing is achieved through the frustum, eliminating the need for additional sealing rings; reducing the number of parts, making assembly more convenient; and providing better sealing performance.

[0013] 2. A column is provided on the side of the valve stem seat located on the elastic element. After assembly, the column presses against the elastic element, and the elastic element forms an inward concave structure; this can achieve complete reset of the valve stem (in the existing technology, incomplete reset may occur, causing liquid to flow out continuously).

[0014] 3. A stainless steel sleeve is placed on the outside of the valve nozzle. Since rats have sharp teeth, using a stainless steel tube can prevent rats from chewing it up.

[0015] 4. An annular plate is provided at one end of the valve nozzle. The annular plate increases the contact area between the valve nozzle and the bag body, thereby improving the strength of the connection. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0026] Please see Figures 1-6 In this embodiment of the invention, a disposable animal drinking bag includes a bag body 1 and a valve 2. The valve 2 includes a valve nozzle 22, an elastic element 23 (made of silicone tubing), a valve stem 24, and an annular sleeve 25. The elastic element 23 is disposed inside the valve nozzle 22, and a protrusion supporting and limiting the elastic element 23 is provided at the valve nozzle 22 located on the elastic element 23. An annular sleeve 25 is installed at the end of the valve nozzle 22 away from the bag body 1. At least one annular protrusion 251 is provided on the outer side of the annular sleeve 25. An annular groove is formed on the inner wall of the valve nozzle 22 to cooperate with the annular protrusion 251. The cooperation between the annular protrusion 251 and the annular groove serves both to limit movement and to seal against leakage. The valve stem 24 is installed at the annular sleeve 25, and one end of the valve stem 24 abuts against the elastic element 23.

[0027] like Figures 6-7 The valve stem 24 includes a valve stem seat 241, a frustum 242, and a rod body 243. One end of the valve stem seat 241 has a groove 245, and the other end has a frustum 242. The rod body 243 is located at the end of the frustum 242 away from the valve stem seat 241. The diameter of the frustum 242 at the end of the valve stem seat 241 is larger than the inner diameter of the annular sleeve 25, and the diameter of the end of the frustum 242 away from the valve stem seat 241 is smaller than the inner diameter of the annular sleeve 25. Sealing is achieved through the frustum, eliminating the need for an additional sealing ring; reducing the number of parts and making assembly more convenient; and providing better sealing. A column 244 is located on one side of the elastic element 23 on the valve stem seat 241. After assembly, the column 244 compresses the elastic element 23, forming a concave structure in the elastic element 23; this allows for complete valve stem reset.

[0028] like Figures 4-5 It also includes a stainless steel cylinder 21, which is fitted over the valve nozzle 22. Since rats have sharp teeth, the stainless steel cylinder prevents them from damaging the nozzle. The valve nozzle 22 has an annular piece 221 (formed by thermoplastic molding or ultrasonic welding) at one end of the bag body 1. The annular piece 221 increases the contact area between the valve nozzle and the bag body, improving the connection's strength.

[0029] The working principle of this invention is as follows: When the animal's mouth touches the valve stem, the valve stem tilts, and the truncated cone cannot achieve a seal; the water inside the bag flows out through the groove of the valve stem, and the outflowing water flows out through the gap created between the tilted valve stem and the annular sleeve 25, so that the animal can drink the liquid flowing out of the bag through the valve mouth; after the animal has finished drinking, the valve stem returns to its original position under the elastic force of the elastic element. At this time, the truncated cone of the valve stem and the annular sleeve 25 are properly sealed, and the liquid inside the bag cannot flow out.

[0030] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
