DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 3 As shown, a special filter for bottled water includes a housing 3, a water outlet filter structure and an air filter structure. The housing 3 includes a sleeve 4 and a water outlet filter chamber 5. The sleeve 4 is fixedly connected to the bottom edge of the water outlet filter chamber 5. The sleeve 4 is sleeved on the outside of the bottle mouth 2. The upper and lower ends of the water outlet filter chamber 5 are respectively connected with connecting pipes 6. A plurality of air channel structures are circumferentially arranged on the side wall of the sleeve 4.

[0025] The water outlet filter structure is arranged inside the water outlet filter chamber 5;

[0026] The air filter structures are arranged in several groups, and are respectively arranged in the corresponding air channel structures.

[0027] In some specific embodiments, such as Figure 3 As shown, in order to facilitate filtering of water, the water outlet filtering structure includes filter cotton 8 and filter plate 9. Two filter cottons 8 are provided and are horizontally fixed at the upper and lower ends of the water outlet filter chamber 5 respectively. A filter plate 9 is fixed between the two filter cottons 8. The filter plate 9 is composed of a filter mesh plate filled with activated carbon particles.

[0028] When water flows inside the water outlet filter chamber 5, it will pass through the filter cotton 8, the filter plate 9 and the filter cotton 8 in sequence. The filter cotton 8 is made of sponge material, and the particulate matter and odor in the air are removed by utilizing the filtering effect of the sponge material. Since the plastic water bucket material will release plastic particles into the drinking water during the water storage process, the filter plate 9 is composed of a filter plate filled with activated carbon particles. The filter plate 9 can absorb the plastic particles in the water and improve the taste of the drinking water. It has three layers of filtration and can effectively filter the water quality of the barreled water bucket 1.

[0029] In some specific embodiments, such as Figure 3 As shown, in order to facilitate the introduction of air into the bottled water bucket 1, each group of air channel structures includes an air inlet 10, an air filter chamber 11 and a bent through hole 15. The air inlet 10 is arranged at the bottom of the side wall of the sleeve 4, the air filter chamber 11 is vertically arranged in the middle position of the side wall of the sleeve 4, the bent through hole 15 is arranged at the top of the sleeve 4, one end of the air filter chamber 11 is connected with the air inlet 10, and the other end is connected with the bent through hole 15. The end of the bent through hole 15 away from the air filter chamber 11 is connected with the internal space of the sleeve 4, and an air filtering structure is arranged inside the air filter chamber 11. By arranging the air inlet 10, the air filter chamber 11 and the bent through hole 15, the outside world is connected with the inside of the bottle mouth 2, so as to facilitate the external air to enter the bottled water bucket 1 to balance the air pressure.

[0030] In some specific embodiments, in order to facilitate the filtering of incoming air, each group of air filtration structures includes a sterilizing filter plate 12, an activated carbon plate 13 and a non-woven fabric 14. The sterilizing filter plate 12, the activated carbon plate 13 and the non-woven fabric 14 are fixedly connected in sequence inside the air filter chamber 11 from top to bottom. The sterilizing filter plate 12 is mainly composed of sterilizing ceramic ball filter material.

[0031] First, the air passes through the non-woven fabric 14, which can filter out large particles in the air. Then the air passes through the activated carbon plate 13, which is made of activated carbon material. The adsorption capacity of the activated carbon material is used to remove harmful gases and odors in the air. When the air passes through the activated carbon particles on the plate, the harmful gases and odor substances will be adsorbed on the surface of the activated carbon, thereby purifying the air. After being filtered by the activated carbon plate 13, the air flows upward and passes through the sterilization filter plate 12. The sterilization filter plate 12 combines the physical properties and sterilization function of the sterilization ceramic ball filter material, which can effectively inhibit the growth of bacteria, fungi and other microorganisms, thereby achieving the effect of sterilizing and disinfecting the air entering the bottled water bucket 1.

[0032] In some specific embodiments, such as Figure 2 As shown, in order to facilitate the absorption of water in the barreled water bucket 1, a water-absorbing silicone tube 7 is sleeved on the outer side of the connecting tube 6 near the bottle mouth 2, and the end of the water-absorbing silicone tube 7 away from the connecting tube 6 extends to the bottom of the barreled water bucket 1, and the end of the other connecting tube 6 is connected to a tea table pump or a barreled water pump, so as to absorb the water in the barreled water bucket 1 after filtering through the water outlet filter structure.

[0033] In some specific embodiments, such as Figure 3 As shown, in order to enhance the sealing performance of the connection between the bottle mouth 2 and the sleeve 4, a silicone sealing sleeve 16 is provided between the sleeve 4 and the bottle mouth 2 for sealing the connection between the bottle mouth 2 and the entire shell 3 to reduce air leakage, while ensuring that the air entering the bottled water bucket 1 is sterilized and filtered.

[0034] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0035] When the tea bar machine, tea table pump, bottled water pump and drinking fountain pump are working to draw drinking water from the bottled water bucket 1, the water in the bucket enters the water outlet filter structure through the water absorption silicone tube 7, and then enters the water outlet filter chamber 5, first passes through the filter cotton 8 to filter out impurities in the water, then passes through the filter plate 9, the activated carbon inside the filter plate 9 can absorb plastic particles in the water, and then filters impurities in the water again when passing through the filter cotton 8 at the top, and finally flows into the pumping equipment from the upper connecting pipe 6. After adsorption and filtration operations, the water quality in the barrel can be effectively filtered.

[0036] While pumping water, the pressure in the barreled water bucket 1 drops below the air pressure. At this time, the air outside the barreled water bucket 1 enters the air filtration structure through the air inlet 10 under the action of atmospheric pressure. First, the air passes through the non-woven fabric 14 to filter out large particles of dust for the first time, and then passes through the activated carbon plate 13 for a second filtration. The activated carbon can adsorb harmful gases and odor substances in the air. Finally, it passes through the sterilization filter plate 12 for sterilization. The purified air enters the barreled water bucket 1 through the bent through hole 15, and the air entering the barreled water bucket 1 is sterilized and filtered to eliminate bacteria and viruses in the air, reduce air pollution of bottled drinking water, and is more beneficial to the health of drinkers. A silicone sealing sleeve 16 is provided between the sleeve 4 and the bottle mouth 2 to seal and connect the bottle mouth 2 and the sleeve 4 to reduce air leakage. At the same time, it can ensure that the air entering the barreled water bucket 1 has been sterilized and filtered.

[0037] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
