[0024] In order to make the technical solutions, objectives and advantages of the present utility model clearer, the present utility model will be further explained below in conjunction with the accompanying drawings and embodiments.

[0025] As Figure 1 shown, an ozone catalyst water purification system of the present utility model includes a raw water inlet end 1, a purified water outlet end, a first filtering device 71, an ozone generating device 3, a water pump 4, and a first ejector 51; an inlet water flow path is formed between the raw water inlet end 1 and the water inlet side of the first filtering device 71; an ozone generating path is formed by connecting the raw water inlet end 1, the ozone generating device 3, and the first inlet of the first ejector 51; a first mixed flow path is formed between the purified water side of the first filtering device 71 and the second inlet of the first ejector 51; a second mixed flow path is formed among the jet outlet of the first ejector 51, the water pump 4, and the water inlet side of the first filtering device 71; a purified water flow path is formed between the purified water side of the first filtering device 71 and the purified water outlet end.

[0026] Its application principle is as follows:

[0027] When the purified water outlet end is opened, the raw water inlet end 1 is opened, and the ozone generating device 3 is started. The raw water inlet end 1 introduces water source. A part of the water source is input into the first filtering device 71 through the inlet water flow path for filtering to obtain purified water; among the obtained purified water, a part of the purified water can be led out through the purified water flow path by the purified water outlet end; another part of the purified water flows to the second inlet position of the first ejector 51 through the first mixed flow path.

[0028] Another part of the water source generates ozone gas by the ozone generating device 3 through the ozone generating path. The obtained ozone gas is mixed with the purified water input from the second inlet of the first ejector 51 to generate purified water incorporated with ozone, which is pressurized by the water pump 4 and flows back to the water inlet side of the first filtering device 71 through the second mixed flow path. The purified water containing ozone is mixed with the water source introduced by the raw water inlet end 1 again to obtain a water source containing ozone, and then is filtered by the first filtering device 71 again. In this way, the cycle is carried out for ozone generation and water source mixing, so that the purified water containing ozone can be output through the purified water flow path by the purified water outlet end for external application. The setting of the ejector structure can fully mix the ozone gas generated in the ozone generating device 3 with the introduced water source, so that the water source mixed with the gas can quickly reach the supersaturated state.

[0029] As a preferred embodiment, an inlet control valve 61 is provided on the water outlet side of the raw water inlet end 1, and a preliminary filtration device 73 is provided between the raw water inlet end 1 and the inlet control valve 61; an inlet check valve 81 is provided between the inlet control valve 61 and the water inlet side of the first filtration device 71. The preliminary filtration device 73 includes a PP cotton composite carbon filter element. The PP cotton composite carbon filter element can simultaneously remove particulate matter in water, by-products of tap water disinfection and the derived organic matter. Through the above settings, the input of the raw water source can be controlled and the preliminary filtration application requirements of the water source can be met, and the setting of the corresponding check valve structure effectively guides the unidirectional export of the water source.

[0030] In the ozone generation channel, a second filtration device 72 is provided between the raw water inlet end 1 and the ozone generation device 3. Specifically, the second filtration device 72 is provided at the water outlet end of the inlet control valve 61. A first check valve 82 is provided between the second filtration device 72 and the ozone generation device 3, and a second check valve 83 is provided between the ozone generation device 3 and the first inlet of the first ejector 51. The second filtration device 72 includes a cation and anion exchange resin filter element. The cation and anion exchange resin filter element can prepare high-purity water for the use of the ozone generation device 3. Through the above settings, the filtration application requirements of the water source input to the ozone generation device 3 can be met, and the setting of the corresponding check valve structure effectively guides the unidirectional export of the water source.

[0031] In the first mixing flow channel, a proportional valve 62 is provided between the purified water side of the first filtration device 71 and the second inlet of the first ejector 51; a reflux check valve 84 is provided between the proportional valve 62 and the second inlet of the first ejector 51. Through the setting of the proportional valve 62, the purified water filtered by the first filtration device 71 can be controlled to flow back at a certain ratio for mixing with ozone gas; the setting of the corresponding check valve structure effectively guides the unidirectional export of the water source.

[0032] The first filtration device 71 includes an activated carbon filter element with a catalyst and an ultrafiltration filter element; when water flows through the activated carbon filter element with a catalyst, heavy metal ions will be adsorbed by it or react with ozone under its catalytic action to produce precipitates, and most of the ozone is consumed in this stage of the filter element. The function of the ultrafiltration filter element is to intercept fine particulate matter in the front-end water.

[0033] The water outlet end of the purified water is preferably set as a structure of a water purification faucet 2. A three-way valve 63 is arranged in the water purification faucet 2. The water inlet of the three-way valve 63 is communicated with the purified water side of the first filtering device 71. The first outlet of the three-way valve 63 is communicated with the second inlet of the first ejector 51. The second outlet of the three-way valve 63 is communicated with the water outlet end of the water purification faucet 2. Through the setting of the water purification faucet 2 with a three-way structure, the application situations of water source derivation and water source reflux can be effectively taken into account. A pressure switch 64 is arranged between the purified water side of the first filtering device 71 and the water inlet of the three-way valve 63, and the specific input pressure of the water source is controlled through the setting of the pressure switch 64 for application.

[0034] Embodiment 2:

[0035] As Figure 2 shown, the difference between this embodiment and the above Embodiment 1 lies in that the setting of a second ejector 52 is further included. A water inlet flow path is formed between the raw water inlet end 1 and the first inlet of the second ejector 52. A second mixed flow path is formed among the jet outlet of the first ejector 51, the water pump 4, and the second inlet of the second ejector 52. A purified water flow path is formed among the jet outlet of the second ejector 52, the first filtering device 71, and the purified water outlet end.

[0036] Through the combined setting of the second ejector 52 and the first ejector 51, the ozone and the ozone-containing water source can be more fully mixed to ensure that the ozone content in the water source is supersaturated.

[0037] The above are only the preferred embodiments of the present invention. For those skilled in the art of this technology, without departing from the implementation principle of the present invention, the above embodiments can still be modified, and the corresponding modified solutions should also be regarded as the protection scope of the present invention.
