Description

Technical Field

The slow-release osmotic sterilization and filtration technology is a new type of drinking water treatment method that integrates a variety of advanced technologies, and is committed to providing users with healthy, safe and convenient drinking water. The slow-release osmotic sterilization system uses slow-release materials to continuously release sterilizing factors, such as silver ions, chlorine, etc. These sterilizing factors can effectively kill microorganisms such as bacteria, viruses, and algae in water, inhibit the growth and reproduction of microorganisms, thereby ensuring the hygiene and safety of water quality. Moreover, slow-release sterilization has the advantages of being persistent and stable, not requiring frequent replacement of medicaments, and being easy to operate, greatly reducing the maintenance cost and use difficulty of the equipment. Combined with osmotic filtration technology, it can further ensure the hygiene and safety of water quality.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1:

[0020] As Figures 1-9 shown, the embodiment of the present invention provides a slow-release penetration sterilization and filtration drinking water device, which includes: a water tank assembly 1, a slow-release assembly 3, a first filtration assembly 5, and a pumping / supplying air assembly 4.

[0021] The top of the sink assembly 1 is provided with a three-step top shell 2. The shape of the three-step top shell 2 is designed to facilitate the installation of the first filtration component 5 and the air extraction / supply component 4. The sink assembly 1 and the three-step top shell 2 form a "disinfection cavity". The slow-release component 3 is fixedly installed at the top of the middle step of the three-step top shell 2, and the bottom of the slow-release component 3 is fixedly connected to the inner bottom of the sink assembly 1. The tap water after preliminary filtration enters the "disinfection cavity" formed by the sink assembly 1 and the three-step top shell 2. Most of the slow-release component 3 is also located in the "disinfection cavity". The tap water in the "disinfection cavity" enters the inside of the slow-release component 3 and dissolves the slow-release agent (such as chlorine dioxide solid slow-release agent, peracetic acid solid slow-release agent, potassium permanganate solid slow-release agent, etc.) provided inside the slow-release component 3, so as to realize the sterilization and disinfection treatment of the liquid inside the sink assembly 1. The first filtration component 5 is installed at the top of the bottom step of the three-step top shell 2. The first filtration component 5 is a combined chip of an activated carbon filtration chip and a semi-permeable membrane filtration chip, generally adopting the following two methods. The first method: semi-permeable membrane filtration chip + post-activated carbon filtration chip. The second method: pre-activated carbon filtration chip + semi-permeable membrane filtration chip + post-activated carbon filtration chip. The above-mentioned pre-activated carbon filtration chip, semi-permeable membrane filtration chip, and post-activated carbon filtration chip can all be one layer or multiple layers. The air extraction / supply component 4 is fixedly installed on the side of the slow-release component 3, and the top of the slow-release component 3 is close to the air extraction / supply component 4. When the air extraction / supply component 4 fills the inside of the slow-release component 3 with gas, the gas will form an "air pressure mass" at the top of the slow-release component 3. The designed position of the air extraction / supply component 4 ensures that when the "air pressure mass" is extracted subsequently, as little liquid inside the slow-release component 3 as possible is extracted. On a pair of opposite sides of the sink assembly 1, a water inlet 101 and a water outlet 102 are respectively opened. An inlet hole 301c is opened on the side of the slow-release component 3 close to the water inlet 101, and an outlet hole 301b is opened on the side of the slow-release component 3 close to the first filtration component 5.

[0022] During use, the tap water after preliminary filtration is added into the inside of the sink assembly 1 from the water inlet 101. The tap water fills the inside of the "disinfection cavity", and the tap water enters the inside of the slow-release component 3 from the inlet hole 301c and dissolves the slow-release agent (such as chlorine dioxide solid slow-release agent, peracetic acid solid slow-release agent, potassium permanganate solid slow-release agent, etc.) provided inside the slow-release component 3, so as to realize the sterilization and disinfection treatment of the liquid inside the sink assembly 1. When water needs to be added in the subsequent process, control the air extraction / supply component 4 to work. The air extraction / supply component 4 fills the inside of the slow-release component 3 with air, and these airs form a high-pressure "air pressure mass" at the inner top of the slow-release component 3 to pressurize the water inside the "disinfection cavity". The water passes through the first filtration component 5 (a kind of osmotic filtration part) composed of an activated carbon filtration chip and a semi-permeable membrane filtration chip.

[0023] During the operation of the above-mentioned pumping / supplying air component 4, the liquid inside the slow-release component 3 is pushed outwards, which can promote the mixing of the disinfectant solution (tap water dissolved with the slow-release agent) and other tap water, ensure the stability of the concentration of the disinfection solution inside the "disinfection cavity", and achieve a better disinfection and sterilization effect. Generally, when 3 / 4 of the solution inside the slow-release component 3 is pressed out, the pumping / supplying air component 4 is controlled to stop working, and the pumping / supplying air component 4 pumps air into the slow-release component 3 to replenish tap water into the water tank component 1 from the water inlet 101. After the above process is completed, a certain amount of water will be produced. This water is supplied to the drinking water component, and then the above work is repeated to intermittently produce water.

[0024] In the present invention, by integrating the water tank component 1, the slow-release component 3, the first filtration component 5, and the pumping / supplying air component 4, when in use, the liquid inside the water tank component 1 is sterilized by relying on the slow-release agent provided inside the slow-release component 3. When water needs to be added in the subsequent process, the pumping / supplying air component 4 is controlled to work. The pumping / supplying air component 4 fills air into the slow-release component 3, and these airs form a high-pressure "air pressure mass" at the inner top of the slow-release component 3 to pressurize the water inside the "disinfection cavity", so that the water passes through the first filtration component 5 for osmotic filtration. The device has a simple structure, high integration, and can complete intermittent osmotic filtration without using a high-pressure water pump for pressurization, which is applicable to drinking water equipment in families and factories, improving the overall water quality and water use safety of people.

[0025] In an embodiment, a water supply cavity 7 is fixedly connected to the water inlet 101 of the water tank component 1. The water tank component 1 is designed as a square structure. The water supply cavity 7 is used to cooperate with the water inlet 101 on the side of the water tank component 1. The water inlet connection port of the water supply cavity 7 is connected to a water supply component 9. One end of the water supply component 9 is connected to tap water. After the water supply component 9 preliminarily filters the tap water, it is sent into the water supply component 9. A purified water cavity 6 is fixedly connected to the water outlet 102 of the water tank component 1. The purified water cavity 6 is a temporary cavity. When there is water inside the purified water cavity 6, it should be pumped away in time. One side of the purified water cavity 6 is connected to a drinking water component 8, and the drinking water component 8 is convenient for people to receive water for drinking.

[0026] In an embodiment, the water supply cavity 7 includes: a U-shaped housing 701, an interface pipe 702, and a plug 703; the U-shaped housing 701 is horizontally buckled and fixed on the side of the water tank component 1, and the water inlet 101 is communicated with the U-shaped housing 701. Generally, the water inlet 101 is opened as a rectangle, and the U-shaped housing 701 is fixedly welded to the water tank component 1 to ensure the sealing performance of the connection; both ends of the U-shaped housing 701 are fixedly connected with interface pipes 702. One of the interface pipes 702 is connected to the water supply component 9, and a plug 703 is fixedly installed on the other interface pipe 702. One of the two interface pipes 702 is for use, and the other is for standby. The standby interface pipe 702 is installed with a plug 703 for temporary blocking.

[0027] In one embodiment, the water supply assembly 9 includes: a connecting water pipe 902, an adapter pipe 901, a second one-way valve 903, an electromagnetic control valve 904, and a pre-filter assembly 905.

[0028] The first end of the connecting water pipe 902 is connected to the interface pipe 702 through the adapter pipe 901. The water outlet interface of the pre-filter assembly 905 is fixedly connected to the second end of the connecting water pipe 902. The pre-filter assembly 905 further has a water inlet interface 905a, and the water inlet interface 905a is connected to the municipal water supply pipe. A second one-way valve 903 and an electromagnetic control valve 904 are installed on the connecting water pipe 902, and the second one-way valve 903 is close to the adapter pipe 901.

[0029] When in use, the municipal water supply pipe has a certain water pressure. When the electromagnetic control valve 904 is opened, the tap water flows through the water inlet interface 905a through the pre-filter assembly 905 for pre-filtering treatment. Here, a filter screen for generally filtering sand can be mainly used. After preliminary filtering, the water flows through the adapter pipe 901 into the water supply cavity 7, and then into the sink assembly 1.

[0030] By designing the second one-way valve 903, it allows the tap water to flow towards the inside of the sink assembly 1. When the water pressure inside the sink assembly 1 is relatively high, the second one-way valve 903 prevents the backflow of water.

[0031] In one embodiment, the drinking water assembly 8 includes: a collecting water pipe 801, a plurality of heating water tanks 805, a water supply pump 802, a plurality of branch pipes 803, a control valve group 804, a connecting pipe 806, and a water outlet pipe 807.

[0032] The first end of the collecting water pipe 801 is connected to the purified water cavity 6. A water supply pump 802 is connected to the second end of the collecting water pipe 801. When the water supply pump 802 works, the water inside the purified water cavity 6 is pumped away through the collecting water pipe 801; the water outlet end of the water supply pump 802 is connected to a connecting pipe 806, and a branch pipe 803 is connected between the connecting pipe 806 and each heating water tank 805. A control valve group 804 is installed on the branch pipe 803. The number of the control valve groups 804 is the same as that of the branch pipes 803, and they are installed in one-to-one correspondence. A water outlet pipe 807 is fixedly arranged on the side of the heating water tank 805, and a water outlet valve is designed at the water outlet pipe 807 for users to receive water for drinking.

[0033] When in use, when the water level inside one of the heating water tanks 805 is lower than the preset threshold, the control valve group 804 on the corresponding branch pipe 803 is opened, and the water supply pump 802 pumps the water inside the purified water cavity 6 through the collecting water pipe 801 and pumps the water into the corresponding heating water tank 805.

[0034] In one embodiment, a drainage plate 103 is fixedly connected to the inner side of the water tank assembly 1. A narrow flow channel is formed between the drainage plate 103 and the slow-release assembly 3. By designing the narrow flow channel, the water inside the water tank assembly 1 can flow, and it is not necessary to completely pass through the water outlet holes 301b and the water inlet holes 301c on the slow-release assembly 3.

[0036] In one embodiment, the air extraction / supply assembly 4 includes: a two-way pump 401, a water storage device 402, and an air-water separation channel 403.

[0037] The two-way pump 401 is fixedly installed on the side of the slow-release cylinder body 301, and the first interface of the two-way pump 401 is communicated with the inside of the slow-release cylinder body 301. The water storage device 402 is fixedly connected to the water tank assembly 1. The second interface of the two-way pump 401 is communicated with the water storage device 402 through the air-water separation channel 403. The first working state of the two-way pump 401: pumping air into the slow-release assembly 3. At this time, the air can directly enter the air-water separation channel 403 from the side of the air-water separation channel 403 and then enter the two-way pump 401. The second working state of the two-way pump 401: pumping out the air in the slow-release assembly 3, pumping the gas into the water storage device 402 through the air-water separation channel 403. A condensate plate is arranged inside the water storage device 402, and the water vapor in the airflow containing water vapor will liquefy, and the water is stored in the water storage device 402.

[0038] In one embodiment, the air-water separation channel 403 includes: a large-diameter cylinder body 403a, a conical section 403b, a small-diameter pipe 403c, an outer-edge cylinder body 403d, a core pipe 403e, an annular air filter cotton core 403f, an annular partition 403g, and a rubber ring 403h.

One end of the small-diameter pipeline 403c far from the large-diameter cylinder body 403a is connected to the water storage device 402. A condensate plate is arranged inside the water storage device 402. A first one-way valve 404 is installed on the small-diameter pipeline 403c. The first one-way valve 404 allows air to flow from the small-diameter pipeline 403c towards the water storage device 402. The first end of the core pipe 403e is fixedly connected to the second interface of the two-way pump 401. The second end of the core pipe 403e is fixedly connected to the second end of the large-diameter cylinder body 403a through the annular partition plate 403g. An air vent 403g1 is opened on the annular partition plate 403g. A rubber ring 403h corresponding to the annular partition plate 403g is fixedly connected to the inner side of the large-diameter cylinder body 403a. An outer edge cylinder body 403d is fixedly connected to the second end of the large-diameter cylinder body 403a and on the outer side of the core pipe 403e. An annular area is formed between the outer edge cylinder body 403d and the core pipe 403e. An annular air filter cotton core 403f is fixedly arranged inside the annular area.

[0040] External air can flow through the annular area, pass through the air filter cotton core 403f and the air vent 403g1 on the annular partition plate 403g and flow into the core pipe 403e, and then be pumped into the slow-release component 3 by the two-way pump 401; the gas containing water vapor pumped out by the two-way pump 401 flows out through the core pipe 403e. The gas squeezes the rubber ring 403h, and the rubber ring 403h deforms to completely block the air vent 403g1 on the annular partition plate 403g. At this time, the gas containing water vapor can only flow into the water storage device 402 through the large-diameter cylinder body 403a, the tapered section 403b, and the small-diameter pipeline 403c.

[0041] Embodiment Two:

[0042] The embodiment of the present invention provides a usage method of a slow-release osmotic sterilization and filtration drinking water device. Using the slow-release osmotic sterilization and filtration drinking water device in Embodiment One, it specifically includes the following steps: S1. Add preliminarily filtered water into the water tank assembly 1. Pre-filtration can improve the service life of the slow-release osmotic sterilization and filtration drinking water device. The preliminarily filtered water enters the slow-release component 3, and the slow-release agent dissolves into the preliminarily filtered water to perform sterilization and disinfection treatment on the preliminarily filtered water.

[0043] S2. Control the air extraction / supply component 4 to fill air into the slow-release component 3 to form a high-pressure gas mass inside the slow-release component 3. The high-pressure gas mass compresses the water after sterilization and disinfection treatment inside the slow-release component 3, so that the water after sterilization and disinfection treatment is pressurized and permeated and filtered through the first filtration component 5 to obtain the treated water.
