Description

Technical Field

[0001] This invention relates to the technical field of water treatment equipment, and more particularly to a water purifier with a filter cartridge sterilizer. Background Technology

[0002] To further improve water quality and protect people's drinking water health, ozone generators are typically installed in water purification equipment. These generators work in conjunction with the filtration system to further disinfect and sterilize the purified water produced by the filtration system before it is supplied to consumers. However, as ozone generators age and their internal electrical components deteriorate, their performance gradually declines, leading to reduced ozone generation efficiency and purity. Therefore, regular replacement of the ozone generator is necessary in practical applications. However, existing water purification systems often have large ozone generators, requiring a separate cavity separate from the filtration system to install the ozone sterilizer. This increases the overall size of the water purification equipment, making installation inconvenient for users. Furthermore, traditional ozone generators typically require independent water flow and air flow circuits, complicating the piping layout between the ozone sterilizer and the filtration system, resulting in low assembly efficiency and difficult maintenance.

[0003] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0004] This invention addresses the problems mentioned above, such as the large size of ozone sterilizers in existing water purification equipment, which increases the size of the water purification equipment, making it inconvenient to install, and the complex piping layout between the ozone sterilizer and the filter device of the water purification equipment, resulting in low assembly efficiency and difficult maintenance. The invention proposes a water purifier with a filter cartridge sterilizer.

The interface section includes a raw water inlet, a pure water outlet, and a wastewater outlet that are respectively connected to the raw water inlet channel, the pure water outlet channel, and the wastewater outlet channel. The sterilizer is located on the upper part of the water circuit board and close to the interface section.

[0008] As described above, the water purifier with a filter-type sterilizer has a sterilization water path inside the sterilizer. The sterilization water path includes a sterilization inlet channel, a sterilization chamber, and a sterilization outlet channel connected in sequence. The sterilization inlet channel and the sterilization outlet channel are respectively connected to the pure water output channel. The sterilization chamber is used to sterilize pure water.

[0009] As described above, the water purifier with a filter-type sterilizer includes a sterilizer body and a mounting bracket detachably connected to the sterilizer body. The sterilizer is detachably connected to the water circuit board via the mounting bracket. The sterilization inlet channel and the sterilization outlet channel are respectively located on both sides of the mounting bracket, and the sterilization chamber is located inside the sterilizer body.

[0010] The water purifier with a filter-type sterilizer as described above further includes an inner casing.

The first casing has a water circuit board mounting cavity for mounting a water circuit board, and the second casing has a filter cartridge mounting cavity for mounting the filter cartridge module. The mounting partition has a first filter cartridge assembly port communicating between the water circuit board mounting cavity and the filter cartridge mounting cavity. The water circuit board mounting cavity extends along the length direction of the first casing, and the filter cartridge mounting cavity extends along the height direction of the second casing. The extension direction of the water circuit board mounting cavity is perpendicular to the extension direction of the filter cartridge mounting cavity, and the mounting directions of the water circuit board and the filter cartridge module are parallel to the extension direction of the filter cartridge mounting cavity.

[0011] As described above, in a water purifier with a filter cartridge sterilizer, the bottom of the second housing is provided with a second filter cartridge assembly port that communicates with the filter cartridge mounting cavity.

[0012] As described above, the water purifier with a filter-type sterilizer further includes a first mounting cavity between the first housing and the second housing. The first mounting cavity communicates with the water circuit board mounting cavity and extends along the height direction of the inner housing.

[0013] As described above, the water purifier with a filter-type sterilizer further includes a second mounting cavity located below the first mounting cavity and a mounting port located on one side of the second mounting cavity inside the second housing.

[0041] Example 1:

[0042] like Figure 1 As shown in Figure 12, this invention provides a water purifier with a filter cartridge sterilizer, including a filtration system. The filtration system includes a water circuit board 1, a filter cartridge module, and a sterilizer 3. The water circuit board 1 has a water supply circuit, which includes a raw water input channel 111, a pure water output channel 112, and a wastewater output channel 113. The raw water input channel 111 is used to connect to an external water source and input raw water into the filtration system. The raw water includes at least tap water. The filter cartridge module has a purified water channel connected to the water supply circuit. The purified water channel is used to prepare purified water and pure water. The water purifier receives raw water from the raw water input channel 111 through the purified water channel and filters the raw water to produce purified water and pure water. The pure water is discharged to the outside for people to use through the pure water output channel 112, and the wastewater generated during filtration is discharged through the wastewater output channel 113.

[0043] The sterilizer 3 is located in the pure water output channel 112. Pure water filtered by the filter module enters the pure water output channel 112 and flows through the sterilizer 3. The sterilizer 3 directly disinfects and sterilizes the pure water to improve the water quality and protect people's health. Moreover, in this embodiment, the sterilizer 3 can be directly installed on the water circuit board 1, reducing the number of pipe connections for the sterilizer 3 and simplifying the connection structure of the sterilizer 3 in the filtration system. This optimizes the pipe layout of the filtration system, facilitates the rapid assembly and subsequent maintenance of the water purifier. In addition, the sterilizer 3 is preferably a small or micro sterilizer 3. By replacing the traditional post-filter with the sterilizer 3, the volume of the filtration system can be further reduced, thereby improving the space utilization rate of the water purifier, reducing the size of the water purifier, and making it easier for users to install the water purifier.

[0044] Example 2:

[0045] Example 2, based on Example 1, has the following implementation method, such as... Figure 6As shown, an interface section 12 is provided on one side of the water circuit board 1. The interface section 12 includes a raw water inlet 121, a pure water outlet 122, and a wastewater outlet 123, which are respectively connected to the raw water inlet channel 111, the pure water outlet channel 112, and the wastewater outlet channel 113. The raw water inlet 121, the pure water outlet 122, and the wastewater outlet 123 are arranged sequentially along the width direction of the water circuit board 1. Correspondingly, the raw water inlet channel 111, the pure water outlet channel 112, and the wastewater outlet channel 113 are connected to the water circuit board 1. The outlet channels 113 are arranged parallel to each other in sequence along the width direction of the water circuit plate 1. The raw water inlet channel 111, the pure water outlet channel 112, and the wastewater outlet channel 113 extend away from the raw water inlet 121, the pure water outlet 122, and the wastewater outlet 123 along the length direction of the water circuit plate 1, respectively. This facilitates the simplification of the internal pipe layout of the water circuit plate 1, reasonably shortens the length of each pipe in the water circuit plate 1, improves the water conveying efficiency of the water circuit plate 1, and reduces the production cost of the water circuit plate 1.

[0046] The sterilizer 3 is installed on the upper part of the water circuit board 1 and near the interface 12. The top of the water circuit board 1 is provided with an assembly structure for installing the sterilizer 3, so that the sterilizer 3 can be detachably connected to the water circuit board 1. The sterilizer 3 is connected in series in the pure water output channel 112, so that pure water flows directly through the sterilizer 3, allowing pure water to directly enter the sterilizer 3 for further disinfection and sterilization. After disinfection and sterilization, the pure water re-enters the pure water output channel 112 and is discharged, which greatly shortens the pipeline length between the sterilizer 3 and the pure water output channel 112, which is beneficial to improving the disinfection efficiency and output efficiency of pure water. By directly installing the sterilizer 3 on the water circuit board 1 to replace the traditional post-filter, the pure water is further purified to improve water quality and protect people's health.

[0047] Optionally, the sterilizer 3 is configured as an electrolytic ozone generator module. The electrolytic ozone generator module generates low-concentration ozone, which is directly mixed with pure water for disinfection. The disinfected pure water directly enters the pure water output channel 112 and is then output, which improves the disinfection efficiency of pure water and simplifies the connection structure of the sterilizer 3 in the water purifier filtration system. There is no need to set up an additional airflow channel for ozone discharge, which greatly optimizes the pipeline layout of the water purifier in this embodiment, facilitates the rapid assembly and subsequent maintenance of the water purifier, and helps to reduce the size of the filtration system, thereby reducing the size of the water purifier.

[0048] Example 3:

[0049] Example 3, based on any of the above examples, has the following implementation method, such as... Figure 6As shown in Figure 11, the sterilizer 3 is equipped with a disinfection water path, which includes a disinfection inlet channel 311, a disinfection chamber, and a disinfection outlet channel 312 connected in sequence. The disinfection inlet channel 311 and the disinfection outlet channel 312 are respectively connected to the pure water output channel 112. The disinfection water path is connected in series in the pure water output channel 112 and is located near the pure water outlet 122. Pure water in the pure water output channel 112 flows through the disinfection water path. The disinfection chamber is used to disinfect the pure water to achieve disinfection and sterilization of the pure water. Optionally, the sterilizer 3 adopts a modularly designed electrolytic ozone generator. When pure water enters the disinfection chamber through the disinfection inlet channel 311, the sterilizer 3 is triggered to operate by the sterilizer 3 trigger plate, thereby achieving further disinfection of the pure water. The disinfected pure water directly re-enters the pure water output channel 112 through the disinfection outlet channel 312 and is then exported. It should be noted that when the sterilizer 3 adopts a modularly designed electrolytic ozone generator, the ozone generator can be preset to output a low concentration of ozone to ensure that the ozone concentration in the sterilized pure water does not exceed the standard and can be drunk directly.

[0050] The connecting pipe between the disinfection outlet channel 312 and the pure water output channel 112 is located near the pure water outlet 122. Specifically, the top of the water circuit board 1 is provided with a first interface 151 located on the upper part of the pure water output channel 112, and the first interface 151 is close to the output end of the disinfection outlet channel 312. The first interface 151 is connected to the disinfection outlet channel 312 through a first external pipe 161 to shorten the output path of the disinfected pure water and improve the output efficiency of the pure water. It should be noted that the connecting pipe between the disinfection outlet channel 312 and the pure water output channel 112 is the first external pipe 161.

[0051] Optionally, in order to optimize the electrical connection of the sterilizer 3, the connection port of the sterilizer 3 can be set to a Type-C interface.

[0052] Example 4;

[0053] Example 4, based on Example 3, has the following implementation method, such as... Figure 13 As shown in Figure 17, the sterilizer 3 includes a sterilizer body 32 and a mounting bracket 33 detachably connected to the sterilizer body 32. The sterilizer 3 is detachably connected to the water circuit board 1 via the mounting bracket 33. The sterilization inlet channel 311 and the sterilization outlet channel 312 are respectively located on both sides of the mounting bracket 33. The sterilization chamber is located inside the sterilizer body 32.

[0054] Optionally, the top of the water circuit plate 1 is provided with a first mounting post 152 and a second mounting post 153 for mounting the mounting bracket 33. The first mounting post 152 and the second mounting post 153 extend upward. The mounting bracket 33 is provided with a first mounting ear 331 corresponding to the first mounting post 152 and a second mounting ear 332 corresponding to the second mounting post 153. After aligning the first mounting ear 331 and the second mounting ear 332 in the mounting bracket 33 with the first mounting post 152 and the second mounting post 153 one by one, the mounting bracket 33 is fixedly installed on the water circuit plate 1 by fasteners. The sterilizer body 32 is located in the inner cavity of the mounting bracket 33 to realize the detachable connection between the mounting bracket 33 and the water circuit plate 1. The connection structure is simple and easy to operate.

[0055] Since the sterilizer body 32 needs to be replaced periodically to maintain a good sterilization effect, in order to facilitate users to replace the sterilizer body 32 themselves, the installation structure between the sterilizer body 32 and the mounting bracket 33 is further improved in this embodiment. Specifically, as follows: Figure 13 As shown in Figure 17, the top of the sterilizer body 32 is provided with a quick-release locking device 34, which allows the sterilizer body 32 to be detachably installed in the mounting bracket 33. Optionally, the quick-release locking device 34 includes a connecting seat 341 detachably connected to the sterilizer body 32, at least two sets of locking blocks 342 and driving components 343 disposed in the connecting seat 341, and the connecting seat 341 is provided with a first receiving cavity 3411 for accommodating two of the locking blocks 342 and two of the driving components 343. At least two first openings 3412 corresponding to the two locking blocks 342 are provided in the mounting bracket 33. At least two locking holes 333 corresponding to the two locking blocks 342 are provided in the mounting bracket 33. The driving assembly 343 is connected to the locking blocks 342 and is used to drive the locking blocks 342 to extend and retract relative to the first openings 3412 within the first receiving cavity 3411, thereby allowing the locking blocks 342 to be inserted into or disengaged from the locking holes 333, thus realizing the locked and unlocked states of the quick-release locking device 34. In practical applications, such as... Figure 16 As shown, when the quick-release locking device 34 is in the locked state, the locking block 342 extends out relative to the first opening 3412 and inserts into the lock hole 333, thus fixing the sterilizer body 32 into the mounting bracket 33. At this time, the sterilizer body 32 can be used normally. Figure 17As shown, when the drive assembly 343 causes the locking block 342 to retract toward the first receiving cavity 3411 relative to the first opening 3412, so that the locking block 342 disengages from the lock hole 333, the quick-release locking device 34 switches from the locked state to the unlocked state, and the sterilizer body 32 can be removed from the mounting bracket 33; so as to realize the quick disassembly and replacement of the sterilizer body 32, which is convenient for users to operate themselves.

[0056] Furthermore, the drive assembly 343 includes a drive member 3431 and an elastic member 3432 connected to the lock block 342. The drive member 3431 is vertically disposed on the side of the lock block 342 away from the lock hole 333, that is, the drive member 3431 and the lock block 342 form an L-shaped component to facilitate manual operation of the drive assembly 343 by the user. The elastic member 3432 is disposed between the drive member 3431 and the connecting seat 341 and is used to push the drive member 3431 outward relative to the first opening 3412 to facilitate the quick-release locking device 34 to realize the automatic conversion between the unlocked state and the locked state, reduce the user's operating difficulty, and optimize the user experience.

[0057] Example 5:

[0058] Example 5, based on any of the above examples, has the following implementation method, such as... Figure 7As shown in Figure 12, the bottom of the water circuit board 1 is provided with a first filter element mounting position 13 and a second filter element mounting position 14. The first filter element mounting position 13 is located near the interface portion 12, and the second filter element mounting position 14 is located on the other side of the first filter element mounting position 13. The filter element module is detachably connected to the lower part of the water circuit board 1 through the first filter element mounting position 13 and the second filter element mounting position 14. The filter element module includes a first filter element and a second filter element. The first filter element can be set as a pre-filter element, and the second filter element can be set as an RO filter element. The purified water circuit includes a first filtration water circuit located between the first filter element and the water supply water circuit, and a second filtration water circuit located between the second filter element and the water supply water circuit. The first filtration water circuit and the second filtration water circuit are connected in series and connected to the rear side of the raw water input channel 111. The first filtration water circuit includes a first filter element inlet channel and a first filter element purified water channel that are connected to each other. The second filtration water circuit includes a second filter element inlet channel, a second filter element pure water channel, and a second filter element wastewater channel that are connected to each other. The first filter element inlet channel is connected to the raw water input channel 111 and is used to guide raw water into the first filter element for filtration to produce purified water. The first filter element pure water channel is connected to the second filter element inlet channel and is used to output the purified water produced by the first filter element. The second filter element inlet channel is used to guide the purified water into the second filter element for further filtration to produce pure water. The second filter element pure water channel is connected to the pure water output channel 112 and is used to output the pure water produced by the second filter element to the pure water output channel 112. The second filter element wastewater channel is connected to the wastewater output channel 113 and is used to output the wastewater produced by the second filter element to the wastewater output channel 113.

[0059] The first filter element mounting position 13 is provided with a first filter element water inlet 131 and a first filter element clean water inlet 132 corresponding to the first filter element water inlet channel and the first filter element clean water channel, respectively. The second filter element mounting position 14 is provided with a second filter element water inlet 141, a second filter element clean water inlet 142 and a second filter element wastewater inlet 143 corresponding to the second filter element water inlet channel, the second filter element pure water channel and the second filter element wastewater channel, respectively.

[0060] Optionally, an inlet control valve 61 and a booster pump 64 are provided along the water flow direction between the first filter element's purified water flow channel and the second filter element's inlet water flow channel. The inlet control valve 61 is used to control the opening and closing of the second filter element's inlet water flow channel, and the booster pump 64 is used to control the water intake of the second filter element. The top of the water circuit plate 1 is provided with a second interface 154 and a third interface 155 for installing the inlet control valve 61. The second interface 154 is located directly above the first filter element's purified water interface 132. The water circuit plate 1 is provided with... The third interface 155 connects to the first branch 171, which extends along the width of the water circuit plate 1 and is close to the first filter element water purification interface 132. The first branch 171 is connected to the inlet of the booster pump 64 through the second external pipe 162. The booster pump 64 is located on one side of the water circuit plate 1 in the water purifier and is located close to the second filter element. The outlet of the booster pump 64 is connected to the second filter element water inlet 141 through the third external pipe 163.

[0061] Optionally, a check valve 62, a high-pressure switch 65, and the sterilizer 3 are provided along the water flow direction between the second filter element's pure water flow channel and the pure water output flow channel 112. The check valve 62 is horizontally installed on the top of the water circuit board 1. The water circuit board 1 has a second branch 172 perpendicular to the pure water output flow channel 112. The check valve 62 is connected between the second filter element's pure water interface 142 and the second branch 172. The high-pressure switch 65 is installed between the pure water output flow channel 112 and the second branch. At the intersection of 172, the second filter element pure water interface 142, the second branch 172 and the pure water output channel 112 are connected by the check valve 62 and the high-pressure switch 65 to form a pure water output channel; the high-pressure switch 65 is electrically connected to the inlet control valve 61 and is used to control the opening and closing of the inlet control valve 61 to protect the second filter element; in addition, the top of the water circuit board 1 is also provided with a fourth external pipeline 164 connecting the second branch 172 and the disinfection inlet channel 311.

[0062] Optionally, the top of the water circuit plate 1 is also provided with a wastewater control valve 63 connecting the wastewater inlet 143 of the second filter element and the wastewater output channel 113. The top of the water circuit plate 1 is provided with a fourth interface 156 and a fifth interface 157 for installing the wastewater control valve 63. The fourth interface 156 is located directly above the wastewater inlet 143 of the second filter element, and the fifth interface 157 is connected to the wastewater output channel 113. The wastewater output channel 113 extends away from the wastewater outlet 123 along the length direction of the water circuit plate 1, so that the fifth interface 157 is set close to the fourth interface 156.

[0063] like Figure 9 As shown, within the water circuit board 1, the raw water inlet channel 111, the pure water outlet channel 112, and the wastewater outlet channel 113 are arranged parallel to each other along the width direction of the water circuit board 1. The first branch 171 and the second branch 172 are arranged parallel to each other along the length direction of the water circuit board 1. The second branch 172 is perpendicular to the pure water outlet channel 112, and a high-pressure switch 65 is provided at the intersection of the second branch 172 and the pure water outlet channel 112. The end of the wastewater outlet channel 113 is close to the wastewater interface 143 of the second filter element, and the wastewater outlet channel 113 is connected to the wastewater outlet channel 113 through the wastewater control valve 63. The water circuit board 1 designed in this way has simple internal pipes, reduces the manufacturing difficulty of the water circuit board 1, and reasonably shortens the internal pipe length of the water circuit board 1, thereby improving the water conveying efficiency of the water circuit board 1.

[0064] Optionally, in the filtration system, the sterilizer 3 and the second filter element operate synchronously to ensure that the pure water produced by the second filter element can be further disinfected and sterilized by the sterilizer 3 to output disinfected drinking water, improve water quality, and protect people's health.

[0065] Example 6:

[0066] Example 6, based on Example 5, has the following implementation method, such as... Figure 11 As shown, Figure 11 The diagram shows the water flow path for the filtration system to produce pure water under normal conditions, with arrows indicating the direction of water flow. The water circuit board 1 has a dual water output channel 114 connected to the purified water interface 132 of the first filter element. Correspondingly, the interface portion 12 also includes dual water outlets 124 connected to the dual water output channel 114. The dual water output channel 114 is used to output the purified water formed by the first filter element to the outside of the water circuit board 1 for use as domestic water, thereby improving water utilization and avoiding water waste. Furthermore, the dual water output channel 114 is arranged parallel to the raw water input channel 111 and the... The pure water output channel 112 is located between the two water output channels, and the dual water output channel 114 is perpendicular to the first branch 171. One end of the dual water output channel 114 is close to one end of the first branch 171. The second interface 154 and the third interface 155 are located adjacent to each other at the intersection of the dual water output channel 114 and the first branch 171. This facilitates the optimization of the electrical component connection on the top of the water circuit board 1, makes the electrical components configured on the water circuit board 1 neatly installed, facilitates the later maintenance of the electrical components, and reduces the overall volume of the filtration system, thereby reducing the volume of the water purification equipment.

[0067] Example 7:
