[0043] The sterilization functions of the plurality of sterilization devices 14 are activated when the power-on structure 142 is in the power-on state.

[0044] Specifically, the main structure 1 of the filter is usually provided with a water inlet 11 and a water outlet 12, and a filter element 13 is provided inside the main structure 1, for example, a carbon rod filter element, a sintered carbon rod, an extruded carbon rod filter element, etc. When the filter is powered on, water flows into the main structure 1 from the water inlet 11, and the water inside the main structure 1 is purified by the filter element 13, and the purified water flows out from the water outlet 12.

[0045] In order to sterilize at the source of bacterial reproduction and make the sterilization more thorough, the present embodiment adopts a sterilization device 14 including a main body 141 and an electrification structure 142, wherein the main body 141 has a sterilization function, and the electrification structure 142 is used to connect to an external power source to provide power to the main body 141 to activate the sterilization function. By providing a plurality of through holes on the main structure 1, the sterilization device 14 is provided on the main structure 1 through the through holes in a manner that the main body 141 is located inside the main structure 1 and the electrification structure 142 is exposed outside the main structure 1, so that the sterilization device 14 can sterilize the water flow inside the main structure 1.

[0046] It should be noted that the sterilization device 14 can be an LED (light emitting diode) sterilizer, an ultraviolet sterilizer, or any other device capable of achieving a sterilization function, and this embodiment does not specifically limit this.

[0047] This embodiment arranges a number of sterilization devices on the main structure of the filter to activate the sterilization function when powered on, which can not only effectively kill bacteria, but also sterilize at the source of bacterial reproduction, making the sterilization more thorough and avoiding the harm to the human body caused by the metabolic products produced by the reproduction of bacteria in the filter element.

[0048] In a specific embodiment, the main structure 1 includes a bottle body 15 and a cover body 16 covered on the bottle body 15;

[0049] A boss 151 is provided around the cover body 16, and a boss structure 152 is provided on the boss 151;

[0050] The boss structure 152 is used to cooperate with the bottle body 15 to form a closed space.

[0051] Specifically, the main structure 1 can be divided into a bottle body 15 and a cover body 16, wherein a boss 151 is provided around the cover body 16, a boss structure 152 is further provided on the boss 151, a groove is correspondingly provided on the bottle body 15, and the boss structure 152 on the cover body 16 matches with the groove on the bottle body 15, so that the cover body 16 is covered on the bottle body 15 to form a closed space. The cover body 16 can be covered on the bottle body 15 by spin welding to ensure the sealing of the main structure 1.

[0052] In one specific embodiment, a plurality of through holes are provided on the cover 16;

[0053] A first thread structure is provided on the inner surface of each through hole;

[0054] A second thread structure is provided on the outer surface of each sterilizing device 14;

[0055] The first thread structure cooperates with the second thread structure to fix the sterilization device 14 on the cover body 16 .

[0056] Specifically, in order to reduce the difficulty of process implementation, a plurality of through holes can be provided on the cover 16, so that the sterilization device 14 is provided on the cover 16 via the through holes to sterilize the water flow inside the bottle 15. The sterilization device 14 and the cover 16 can be connected by a threaded structure, by providing a first threaded structure (e.g., an external thread) on the inner surface of each through hole, and providing a second threaded structure (e.g., an internal thread) on the outer surface of each sterilization device 14, so that the sterilization device 14 cooperates with the first threaded structure via the second threaded structure, and is screwed into the cover 16. Of course, the first threaded structure can also be an internal thread, and the second threaded structure can be an external thread, which is not specifically limited in this embodiment.

[0057] In a specific embodiment, the cover body 16 is also provided with a detection through hole;

[0058] The water level detection device 17 is disposed on the cover 16 via the detection through hole;

[0059] The water level detection device 17 is used to detect the liquid level in the main structure 1 .

[0060] In a specific embodiment, the water level detection device 17 is a liquid level probe;

[0061] The length of the liquid level probe is shorter than the length of the body 141 .

[0062] Specifically, in order to avoid the sterilization device 14 from running idle, the present embodiment detects the water level by setting a water level detection device 17, for example, real-time water level detection is performed by a liquid level probe, and when a water level signal is detected, the sterilization device 14 is started for sterilization. By setting a detection through hole on the cover body 16, the liquid level probe is arranged on the cover body 16 through the detection through hole, in the same direction as the sterilization device 14, wherein the length of the liquid level probe needs to be less than the length of the body 141, thereby ensuring that when the water level signal is detected, the sterilization device 14 has been placed in the water, and the sterilization device 14 can effectively work.

[0063] In one specific embodiment, the diameter of the power-on structure 142 is larger than the diameter of the through hole;

[0064] A sealing ring 18 is provided on the contact surface between the power supply structure 142 and the main structure 1 .

[0065] Specifically, the diameter of the power-carrying structure 142 in the sterilizing device 14 is set to be larger than the diameter of the through hole to ensure that the power-carrying structure 142 of the sterilizing device 14 is located outside the main structure 1, and at the same time, a sealing ring 18 is provided on the contact surface between the power-carrying structure 142 and the main structure 1 to further ensure the sealing of the main structure 1. For example, when the sterilizing device 14 is provided on the cover 16, the sealing ring 18 is used to seal between the sterilizing device 14 and the cover 16.

[0066] In a specific embodiment, the water outlet 12 includes a first passage 121 and a second passage 122;

[0067] The sterilization device 14 is disposed on the main structure 1 via the first passage 121;

[0068] The body 141 is located inside the main structure 1 , and covers one end of the second passage 122 .

[0069] Specifically, in order to further ensure the sterilization effect, the present embodiment divides the water outlet 12 into a first passage 121 and a second passage 122, wherein the first passage 121 does not discharge water, but is connected to the sterilization device 14, and the main body 141 of the sterilization device 14 covers one end of the second passage 122, that is, the water flow filtered by the filter element 13 will first pass through the sterilization device 14 for re-sterilization before it can flow out through the second passage 122.

[0070] In a specific example, the cover 16 is provided with three through holes for fixing the sterilization device 14 and a liquid level probe, and the inner surface of each through hole is provided with an internal thread. The body 141 of the sterilization device 14 is located inside the bottle 15, and the power supply structure 142 is located outside the bottle 15 and fixed to the cover 16 through the through hole. The detection part of the liquid level probe is located inside the bottle 15 and fixed to the cover 16 through the through hole, and the through hole and the sterilization device 14 and the through hole and the liquid level probe are sealed with a sealing ring 18. At the same time, a groove is also provided at the center of the inner surface of the cover 16, and the groove mainly realizes the positioning and fixing of the inner core upper cover 19. The periphery of the cover 16 is provided with a boss 151, and the boss 151 has a boss structure 152 for spin melting welding.

[0071] The top of the bottle body 15 has a groove for spin welding, which cooperates with the boss structure 152 on the cover body 16. The bottom of the bottle body 15 is provided with a water inlet 11 and a water outlet 12, and has reinforcing ribs for strengthening. The water outlet 12 is divided into two paths, the first path is connected to the sterilizing device 14, and the second path is used to make the water in the bottle body 15 flow out after passing through the sterilizing device 14 connected in the first path.

[0072] One end of the inner core upper cover 19 is limitedly connected to the groove set in the center of the inner surface of the cover body 16, and the other end is installed with one end of the filter element 13. One end of the inner core lower cover 20 is connected to the filter element 13, and the middle of the other end has a through hole connected to the water outlet 12 at the bottom of the filter bottle. The clean water filtered by the filter element 13 will flow out from the through hole. The inner core lower cover 20 and the bottle body 15 are also sealed with a sealing ring 18.

[0073] This embodiment sets several sterilization devices on the main structure of the filter to start the sterilization function when powered on, which can not only effectively kill bacteria, but also sterilize at the source of bacterial reproduction, making the sterilization more thorough and avoiding the harm to the human body caused by the metabolic products produced by the reproduction of bacteria in the filter element. A water level detection device is set in the filter to regularly sterilize the retained water in the main structure. At the same time, when the user takes water, the sterilization device is immediately started for sterilization. By installing sterilization devices on the main structure and water outlet of the filter, the problem of excessive bacteria can be completely eliminated to ensure the safety of users' water use.

[0074] Example 2

[0075] In a specific embodiment of the present disclosure, a water purifier is provided, and the water purifier includes the filter of Example 1.

[0076] Specifically, the filter of Example 1 may be disposed in a water purifier, and the filter may be used to prepare purified water to realize the function of the water purifier.

[0077] In a specific embodiment, the water purifier further includes a main controller;

[0078] Several sterilization devices are electrically connected to the main controller;

[0079] The main controller is used to drive several sterilization devices to start the sterilization work.

[0080] Specifically, the filter can be arranged as a post-filter element in the water purifier and electrically connected to the main controller in the water purifier, so that the start and stop control of the sterilization device can be achieved based on the main controller.

[0081] The following is an explanation of the operating principle of installing the filter as a post-filter in the water purifier:

[0082] like Figure 3-4 As shown, the raw water entering the water purifier first passes through the pretreatment composite filter element for the first filtration, and the water that has passed the first filtration enters the reverse osmosis membrane filter element through the water inlet solenoid valve and the booster pump for the second filtration, and the concentrated water is discharged to the outside of the water purifier through the wastewater solenoid valve, the one-way valve and the concentrated water outlet, and the water that has passed the second filtration is input into the filter, the filter sterilizes the water that has passed the second filtration and performs the third filtration, and then the clean water flows out through the clean water outlet through the water outlet solenoid valve.

[0083] When the water purifier system is used for the first time, the entire machine needs to be flushed when it is powered on and water is supplied for the first time. The flushing is divided into two steps. The first is the flushing mode, that is, the water inlet solenoid valve, booster pump, and wastewater solenoid valve are all turned on. The default time here can be set according to factors such as the size of the filter. The general default time is 30 minutes. After completing the above instructions, continue to complete the water production mode flushing, that is, the water inlet solenoid valve, booster pump, and water outlet solenoid valve are all turned on. The system default is also 30 minutes. You can set it according to the actual time needed.

[0084] After completing the above instructions, the water purifier system is debugged. If the user uses purified water at this time, an electric control signal is given to the faucet, and the faucet will output the signal to the whole machine control system. At this time, the water inlet solenoid valve is turned on, the booster pump is turned on, and the liquid level probe detects the signal in real time. At this time, as long as the liquid level probe detects the signal, the sterilizer is turned on. Since the bottle body of the filter is a pressure filter bottle, after the filter is filled with water for the first time, the user will almost always be full of water during normal use.

[0085] As long as the liquid level probe detects the liquid level signal in real time, the four sterilizers will be turned on for 15 minutes, then turned on for 15 minutes cumulatively and then turned off for 15 minutes, and so on. However, if a water intake signal is given at this time, this signal comes from the water supply of the entire water purifier. In this case, no matter whether the sterilizer is in the closed state or the open state, it must be turned on immediately until the water intake signal stops and the previous unfinished instruction is executed. After the filter sterilization is completed, the total number of colonies in the outlet water quality meets the requirements.

[0086] This embodiment sets several sterilization devices on the main structure of the filter to start the sterilization function when powered on, which can not only effectively kill bacteria, but also sterilize at the source of bacterial reproduction, making the sterilization more thorough and avoiding the harm to the human body caused by the metabolic products produced by the reproduction of bacteria in the filter element. A water level detection device is set in the filter to regularly sterilize the retained water in the main structure. At the same time, when the user takes water, the sterilization device is immediately started for sterilization. By installing sterilization devices on the main structure and water outlet of the filter, the problem of excessive bacteria can be completely eliminated to ensure the safety of users' water use.
