Technical Field
[0001] This utility model relates to an integrated filter bottle device, belonging to the technical field of filter bottle devices. Background Technology
[0002] Currently, there is a problem of backflow of filtered pure water at the outlet of the filter bottle on the market. The existing solution is often to add a one-way check valve, but there is still a risk of check valve failure, which causes the filtered water to flow back into the filter bottle, contaminating the pure water and affecting the overall water flow of the filter bottle.
[0003] The cumbersome replacement and installation of filter bottles in the current market is also a problem that urgently needs to be addressed. Replacing filter elements often requires disassembling and installing multiple parts, resulting in a complicated installation and replacement process and high labor costs. At the same time, the poor integrity of the filter bottle also increases the risk of failure of the overall sealing structure of the filter bottle.
[0004] In existing filter bottle devices on the market, the check valve is subject to water hammer impact, which causes the check valve sealing ring to shift. This affects the seal between the check valve O-ring and the side wall, increasing the risk of pure water flowing back into the liquid bottle. Utility Model Content
[0005] To address the above problems, this utility model provides an integrated filter bottle device, comprising: The bottle cap has a sealed inner cavity at its top, which includes a first cavity, a second cavity, and a third cavity connected sequentially from top to bottom. At least one check valve is fitted in the third cavity, and at least one sealing ring is fitted in the second cavity. A pure water outlet is provided at the top of the first cavity. The bottle cap is also provided with a raw water channel communicating with the outside. A filter bottle, connected to a bottle cap, wherein a filter element is provided inside the filter bottle; There is a gap space at the connection between the filter bottle and the bottle cap. The gap space connects the raw water channel and the filter element. The raw water enters the bottle cap through the raw water channel and enters the filter element in the filter bottle through the gap space to be filtered into pure water. Then, under pressure, it flows out of the pure water outlet through the third chamber, the second chamber, and the first chamber in sequence.
[0006] Furthermore, the diameters of the first cavity, the second cavity, and the third cavity decrease sequentially. A large gear step connects the first cavity and the second cavity, and a small gear step connects the second cavity and the third cavity. A check valve step is provided at the bottom of the third cavity.
[0007] Furthermore, a small gear ring is fitted on the small gear step, and a sealing ring is provided on the top of the small gear ring; a large gear ring is fitted on the large gear step, and a three-part retaining claw is provided on the top of the large gear, so that the small gear ring and the three-part retaining claw can limit and fix the sealing ring.
[0008] Furthermore, the third chamber has two check valves stacked on top of each other, and the second chamber has two sealing rings stacked on top of each other.
[0009] Furthermore, the bottom of the bottle cap is provided with a threaded portion, and the top of the filter bottle is provided with a threaded surface that can engage with the threaded portion.
[0010] Furthermore, there is a stepped gap space at the connection between the filter bottle and the cap.
[0011] Furthermore, the top of the bottle cap is also provided with a wastewater outlet.
[0012] Furthermore, the bottle cap and the side of the filter bottle are fixedly connected to the horizontal filter bottle mounting sheet metal.
[0013] Furthermore, the top of the bottle cap is fixedly connected to the sheet metal for mounting the filter bottle.
[0014] The beneficial effects of this utility model are: This invention optimizes the internal structure of the filter bottle cap and, in conjunction with the layout of the check valve, sealing ring, and raw water channel, provides a backflow prevention structure for the outlet of a double check valve filter bottle. This not only reduces the risk of check valve seal failure but also simplifies the installation process and enhances the overall structural integrity. Furthermore, the filter bottle can be hoisted, either vertically or horizontally mounted on the water treatment sheet metal, simplifying the disassembly and assembly process and facilitating after-sales maintenance and replacement of the filter bottle and filter element.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Specifically, the terms "first position" and "second position" refer to two different positions.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] This utility model provides an integrated filter bottle device, mainly including a filter bottle 2 and a matching bottle cap 1, with a filter element 3 disposed inside the filter bottle 2. Specifically, in some embodiments, the top of the bottle cap 1 has a sealed inner cavity, which is a tubular chamber structure and is connected vertically. In the examples of Figures 2 and 3, the sealed inner cavity includes a first cavity, a second cavity, and a third cavity connected sequentially from top to bottom. The diameters of the first cavity, the second cavity, and the third cavity decrease sequentially to form a spiral tubular structure. Furthermore, a large gear step 21 is formed between the first cavity and the second cavity due to the diameter difference, and a small gear step 20 is formed between the second cavity and the third cavity due to the diameter difference. A check valve step 19 is disposed at the bottom of the third cavity. In the example shown in Figure 3, two check valves 11 are fitted inside the third chamber, stacked one on top of the other to prevent backflow of water; two sealing rings 12, both O-rings, are fitted inside the second chamber to enhance the sealing performance of the bottle opening; a pure water outlet 17 and a wastewater outlet 18 directly connected to the first chamber are provided at the top of the first chamber; a raw water channel 16 connected to the outside and perpendicular to the pure water flow direction is also provided on the side of the bottle cap 1. In some embodiments, the two check valves 11 are stacked so that they fit perfectly into the third chamber. A small gear ring 14 is positioned on top of the upper check valve 11, supported by a small gear step 20. Two sealing rings 12 are then stacked on top of the small gear ring 14. A large gear ring 13 is positioned on top of the upper small gear ring 14, supported by a large gear step 21. A three-part retaining claw 15 is positioned above the large gear ring 13 to cover the top of the first chamber. Since the small gear ring 14 and the check valve step 19 can limit the two check valves 11, they can effectively prevent the backflow of filtered pure water. Using two check valves 11 is equivalent to double protection. Since the large gear ring 13 and the small gear step 20 can limit the two sealing rings 12, they can prevent the sealing rings 12 from shifting and failing. Furthermore, the bottom of the three-part clamping claw 15 can further fix the sealing rings 12, further suppressing the risk of displacement and failure of the sealing rings 12. The above-mentioned stacked structure forms the inner cavity of the integrated bottle cap 1, enhancing the structural integrity, ensuring both sealing effect and preventing backflow of water, thus stably producing pure water. In some embodiments, the top opening of the filter bottle 2 is connected to the bottle cap 1, and a filter element 3 is provided inside the filter bottle 2. In the examples of Figures 2 and 3, the bottom of the bottle cap 1 is provided with a threaded portion, and the top of the filter bottle 2 is provided with a threaded surface that can cooperate with the threaded portion. In the example in Figure 3, there is a stepped gap space at the connection between the filter bottle 2 and the cap 1.
[0021] Because there is a gap space at the connection between the filter bottle 2 and the bottle cap 1, the gap space connects the raw water channel 16 and the filter element 3; the raw water enters the bottle cap 1 through the raw water channel 16 and enters the filter element 3 in the filter bottle 2 through the gap space to be filtered into pure water, and then flows out of the pure water outlet 17 in sequence through the third chamber, the second chamber and the first chamber under pressure.
[0022] Example 1 As shown in Figure 4, the bottle cap 1 and the side of the filter bottle 2 can be fixedly connected to the horizontal filter bottle mounting sheet metal 4 through the hanging ears, thus realizing the horizontal structure of the entire integrated filter bottle device for use in specific environments.
[0023] Example 2 As shown in Figure 5, the top of the bottle cap 1 is fixedly connected to the suspended filter bottle mounting sheet metal 5. With the adoption of the suspended structure, the filter element 3 can be replaced without disassembling the bottle cap 1, making after-sales installation more convenient.
[0024] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
