Description

Technical Field

[0001] This application relates to the field of sports water bottle technology, and in particular to a sports water bottle with a replaceable filter. Background Technology

[0002] Existing sports water bottles are generally designed for sports scenarios such as running and cycling, focusing on being lightweight and convenient. However, for outdoor sports such as legal trekking and hiking, sports water bottles are required to have a large capacity and specific features such as filtering raw water.

[0003] Existing outdoor sports water bottles, such as the wilderness survival sports water bottle disclosed in Chinese Patent Publication No. CN213281923U, achieve clean filtration of outdoor raw water through a coarse filter interception screen, an ultrafiltration filter element, and a multiple heavy metal removal filter element set inside the bottle body. However, since outdoor water may contain bacteria and viruses, drinking it directly after filtration poses a risk of illness. In addition, this filtration device is bulky and fixed inside the bottle body, reducing the bottle's volume. Furthermore, it has low filtration efficiency and, after long-term use, problems such as difficulty in drinking from the spout may arise.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a sports water bottle with a replaceable filter to solve one of the above-mentioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is: a sports water bottle with a replaceable filter cartridge, comprising: a bottle body, the top of which forms an upwardly extending spout, the spout having a plurality of limiting grooves arranged in a ring; a filtration device disposed within the spout, comprising a ceramic filter cartridge and an activated carbon filter cartridge, a PP cotton filter cartridge, and a filter screen placed from bottom to top within the ceramic filter cartridge, the top of which has a plurality of limiting blocks extending outward, the outer sides of which are fixed to a limiting ring, and the limiting blocks being placed within the limiting grooves. The limiting ring is fitted onto the spout of the kettle, and the inner wall of the top of the ceramic filter cartridge is threaded. The kettle lid is threaded to the spout to close it. A threaded post is rotatably mounted on the top wall of the lid, and the threaded post is threaded to the ceramic filter cartridge and can move up and down. An operating component is rotatably mounted on the side wall of the lid, and the operating component passes through the lid and is threaded to the threaded post. By operating the operating component, the threaded post and the ceramic filter cartridge are fixed, making it easy to remove the filter device and replace the filter element.

[0007] In some embodiments, the spout includes a threaded portion at the bottom and a smooth portion at the top. The threaded portion is used to thread into the lid, and the smooth portion is used for the fitting of the retaining ring, which is in close contact with the smooth portion when fitted.

[0008] In some embodiments, a limiting post is fixed inside the lid, and a limiting hole is formed on the threaded post. The limiting post is limited within the limiting hole, and the limiting post moves up and down within the limiting hole as the operating member rotates.

[0009] In some embodiments, the operating member has an operating portion formed thereon, and friction protrusions are arranged around the operating portion.

[0010] In some embodiments, the kettle body is provided with a support ring and a handle. The kettle body is made of stainless steel, the handle is made of high-strength ceramic, and the surface of the kettle body below the support ring is coated with a ceramic particle coating.

[0011] The beneficial effects of this application are as follows:

[0012] 1) The filter device of this application is removed by rotating the operating part on the lid, which drives the threaded column to move downward and engage with the ceramic filter cartridge. This avoids contamination of the spout when the filter device is handled by hand. Removing the filter device as a whole by the lid also helps to pour out the water in the pot, preventing the filter screen and other parts from being poured out when poured out directly. At the same time, this method allows for contactless replacement of the entire filter device, or the activated carbon filter and PP cotton filter in the ceramic filter cartridge can be replaced separately after the filter device is removed from the pot, avoiding contact with the spout.

[0013] 2) The filter device is small in size and is made of ceramic filter cartridge. It is equipped with activated carbon filter, PP cotton filter and filter screen inside. It has high filtration efficiency and can effectively filter out larger impurities. After filtration, the filter device can be removed through the lid and placed on the support ring on the device. The filtered water can be boiled with an open flame to further sterilize it, providing safe drinking water in outdoor environments. The kettle has a large capacity. Attached Figure Description

[0022] The technical solutions of the embodiments of this application 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 this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0023] In the embodiments of this application, please refer to Figure 1-6As shown, this sports water bottle with a replaceable filter mainly includes: a bottle body 1, the top of which forms an upwardly extending spout 2, and the spout 2 having several limiting grooves 3 arranged in a ring; a filtration device, disposed within the spout 2, including a ceramic filter cartridge 4 and an activated carbon filter cartridge 5, a PP cotton filter cartridge 6, and a filter screen 7 placed from bottom to top within the ceramic filter cartridge 4, the top of the ceramic filter cartridge 4 having several limiting blocks 8 extending outward, the outer sides of the multiple limiting blocks 8 being fixed to a limiting ring 9, the limiting blocks 8 being placed within the limiting grooves 3, the limiting ring 9 being sleeved on the spout 2, and the inner wall of the top of the ceramic filter cartridge 4 having threads; a lid 10, which threadedly engages with the spout 2 to close the spout 2, the top wall of the lid 10 having a rotatable threaded post 11, the threaded post 11 threadedly engaging with the ceramic filter cartridge 4 and being able to move up and down; the lid 10... An operating component 12 is rotatably mounted on the side wall of the lid 10. The operating component 12 passes through the lid 10 and is threadedly engaged with the threaded post 11. By rotating the operating component 12, the threaded post 11 and the ceramic filter cartridge 4 are fixed, making it easy to remove the filter device and replace the filter element. Specifically, the filter screen 7 is used to filter larger impurities in the raw water, the PP cotton filter element 6 is used to filter sediment particles in the raw water, and the activated carbon filter element 5 and the ceramic filter cartridge 4 further filter out small impurities in the water and remove odors, thus purifying the water. The ceramic filter cartridge 4 filters through its micropores, resulting in relatively fast water purification efficiency. The PP cotton filter element 6 and the activated carbon filter element 5 need to be replaced regularly depending on the frequency of use, while the ceramic filter cartridge 4 and the filter screen 7 need to be cleaned or replaced regularly depending on the frequency of use. In addition, the threads on the ceramic filter cartridge 4 are located on the inner wall and will not adversely affect the drinking experience.

[0024] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0025] like Figure 2 As shown, the spout 2 includes a threaded portion 201 at the bottom and a smooth portion 202 at the top. The threaded portion 201 is used to thread into the lid 10, and the smooth portion 202 is used for the fitting of the limiting ring 9. When the limiting ring 9 is fitted onto the smooth portion 202, it is in close contact with the smooth portion 202. During normal drinking, water can be drunk through the limiting groove 3 of the spout 2. The number of limiting grooves 3 should not affect the normal drinking action. Alternatively, after cleaning the filter device, the ceramic filter cartridge 4 can be reassembled on the spout 2 for drinking. Or, the filter screen 7, PP cotton filter element 6, and activated carbon filter element 5 can be removed before drinking to avoid drinking impurities filtered out.

[0026] Specifically, the ceramic filter cartridge 5 is engaged with the limiting groove 3 of the spout 2 via the limiting block 8, and the limiting ring 9 is engaged with the smooth part 202 of the spout 2. The ceramic filter cartridge 4 cannot rotate relative to the body 1. When the threaded column 11 rotates and approaches the threaded filter cartridge 4, the threaded filter cartridge 4 will not rotate together, which facilitates the assembly of the two. In addition, the limiting ring 9 on the ceramic filter cartridge 4 can be used as a part for manually removing the filter device. In the case of removing the filter device and needing to replace the internal filter element, the filter device can be held through the limiting ring 9. However, it should be noted that the upper part of the limiting ring 9 should be avoided, and the limiting ring should be cleaned in time.

[0027] Furthermore, a limiting post 13 is fixed inside the lid 10, and a limiting hole 14 is opened on the threaded post 11. The limiting post 13 is limited in the limiting hole 14. The limiting post 13 moves up and down in the limiting hole 14 as the operating member 12 rotates. The limiting post 13 is used to restrict the position of the threaded post 11, so that the threaded post 11 can only move in the vertical direction.

[0028] Specifically, the operating member 12 has an operating part, and friction protrusions 15 are arranged around the operating part. The user rotates the operating member 12 through the operating part. The rotation of the operating member 12 drives the threaded post 11 that is threaded with it to rotate and move in the vertical direction. In this way, the threaded post 11 engages with or disengages from the threaded sleeve, making it convenient to take out and put in the filter device through the lid 10.

[0029] like Figure 6 As shown, the kettle body 1 is provided with a support ring 16 and a handle 17. The kettle body 1 is made of stainless steel, and the handle 17 is made of high-strength ceramic. The surface of the kettle body 1 below the support ring 16 is coated with a ceramic particle coating. After filtering and producing water, the filter device is removed through the kettle lid 10. The kettle body 1 is then placed on another support 18 through the support ring 16 and boiled with an open flame to turn the water in the kettle body 1 into boiled water, providing safe drinking water. The ceramic particle coating can prevent the open flame from blackening the kettle body 1, and the ceramic handle 17 can prevent burns when handling the kettle body 1.

[0030] When using this sports water bottle, first remove the lid 10, then filter the raw water through the spout 2 and the filter device. After filtering, replace the lid 10 and rotate the operating component 12 to make the threaded post 11 engage with the ceramic filter cartridge 4. Then, unscrew the lid 10 to separate the filter device and the lid 10 from the bottle body 1. Then, place the bottle body 1 on the support 18 and boil the raw water in the bottle body 1 over an open flame to sterilize it. When replacing the filter cartridge, the entire filter device can be replaced without contacting the spout 2 through the lid 10. Alternatively, the filter device can be removed from the bottle body 1 through the lid 10, and then the operating component 12 can be rotated to separate the filter device from the lid 10. Then, the activated carbon filter cartridge 5 and the PP cotton filter cartridge 6 inside the ceramic filter cartridge 4 can be replaced separately, and the ceramic filter cartridge 4 and the filter screen 7 can be cleaned.

Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
