[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0031] like Figures 1 to 3As shown in the figure, this utility model discloses an intelligent food purifier, including a purification body 1, a baffle 5, a purification component 4, a probe component 9, and a display component 6. The purification body 1 has a closed chamber 101 and a fixed shaft 11. At least a drive component 2 and a control main board 3 are provided in the closed chamber 101. A limiting part 111 is provided on the outer periphery of the fixed shaft 11. The baffle 5 is arranged around the fixed shaft 11 and is connected to the drive component 2. A positioning part 501 is provided on the baffle 5. The limiting part 111 cooperates with the positioning part 501 to restrict the baffle 5 from detaching from the purification body 1. The purification component 4 is located on the purification body and is used to generate ozone or hydroxyl groups. One end of the probe component 9 extends out of the closed chamber 101 and detects the TOC and COD values ​​of the water. The probe component 9 is connected to the control main board 3. The display component 6 is used to display the TOC and COD values ​​and is connected to the control main board 3.

[0032] In this embodiment, a probe assembly 9 is installed on the purification body 1 to detect the TOC and COD values ​​of the water to provide feedback on changes in the water quality during fruit and vegetable washing. The detected TOC and COD values ​​are displayed to the user through the display assembly 6. The user can intuitively and easily understand the TOC and COD values ​​before and after fruit and vegetable washing, so that the user can determine the washing effect of the fruit and vegetable.

[0033] It should be noted that TOC stands for Total Organic Carbon, and COD stands for Chemical Oxygen Demand; both are commonly used indicators in water quality testing. TOC represents the total amount of organic matter in water, while COD represents the amount of oxygen required for the chemical oxidation of organic matter in water.

[0034] The TOC value in the water where the fruit and vegetable machine is located can be detected by a TOC sensor. The higher the TOC value in the water, the higher the organic matter content in the water. The COD value in the water where the fruit and vegetable machine is located can be detected by a COD sensor. COD and TOC sensors are existing technologies for detecting water quality, and their principles and structures will not be elaborated on here.

[0035] In some embodiments, an end cap 8 is detachably installed on the top of the fixed shaft 11, and a purification chamber is formed between the end cap 8 and the fixed shaft 11. The end cap 8 is provided with a first through hole 801 that connects the inside and outside of the purification chamber. The purification assembly 4 is provided with a first electrolysis module and a second electrolysis module, and the first electrolysis module or the second electrolysis module is installed in the purification chamber.

[0036] Furthermore, a clearance space 503 and a channel connecting the inside and outside of the clearance space are formed between the bottom of the baffle 5 and the purification body 1, and the first electrolysis module or the second electrolysis module is located in the clearance space 503.

[0037] The first electrolysis module can be used alone to generate ozone, and the second electrolysis module can be used alone to generate hydroxyl groups. Ozone and hydroxyl groups are used to sterilize and disinfect the surface of fruits and vegetables.

[0038] In a specific example, the first electrolysis module (not shown in the figure) is located in the clearance space, and the second electrolysis module is located in the purification chamber. The connection between the first and second electrolysis modules and the control mainboard in the closed chamber is existing technology. When the drive component operates, it causes the turbulence component to rotate. The first electrolysis module electrolyzes and generates ozone. Under the high-speed rotation of the turbulence component, the generated ozone can be cut to form bubbles. Some of the ozone dissolves in water to become hydroxyl groups. The second electrolysis module also generates hydroxyl groups. The ozone and hydroxyl groups dissolved in the water sterilize and disinfect the fruits and vegetables.

[0039] Of course, the second electrolysis module can also be placed in the clearance space, while the first electrolysis module is placed in the purification chamber. By placing the first and second electrolysis modules separately in the purification chamber and the clearance space, the overall structure of the fruit and vegetable machine can be miniaturized.

[0040] In some embodiments, a positioning ring (not shown in the figure) is provided on the side of the purification body 1 near the baffle 5 or at the bottom end of the fixed shaft 11, and the positioning ring abuts against the bottom end of the baffle 5.

[0041] By abutting the bottom of the positioning ring against the baffle, the risk of movement interference between the first or second electrolysis module and the baffle within the clearance space is reduced. In addition, the bottom of the baffle is designed to taper upward relative to the first or second electrolysis module, that is, the bottom of the baffle and one side of the purification body form a sufficient clearance space for the first or second electrolysis module to be fixedly installed.

[0042] Of course, the main purpose of this positioning ring is to increase the distance between the bottom of the baffle and one side of the purification body, and increase the height of the clearance space, so that the distance between the first electrolysis module or the second electrolysis module and the baffle is increased. Therefore, a fixing groove can be opened on one side of the purification body, and the first electrolysis module or the second electrolysis module can be installed in the fixing groove, which can also achieve the effect of increasing the distance between the first electrolysis module or the second electrolysis module and the baffle. The specific design depends on the actual situation.

[0043] In some embodiments, the protruding end of the probe assembly 9 is located in the clearance space 503 between the baffle 5 and the purification body 1.

[0044] The probe assembly 9 is installed in a concealed manner to avoid exposing it, reducing its damage rate and improving its aesthetics. This installation does not affect the detection function of the probe assembly 9. The baffle 5 is positioned around the fixed shaft 11 and rotates relative to the purification body 1. Cleaning water can freely enter and exit the clearance space 503 formed between the baffle 5 and the purification body 1. The probe assembly 9, installed within this clearance space 503, can detect the TOC and COD values ​​of the water.

[0045] Of course, the probe assembly 9 may be installed in other locations on the purification body 1, as long as the probe assembly 9 can detect the water quality for cleaning fruits and vegetables.

[0046] The probe assembly is equipped with an online OPR sensor for OPR value, and the display assembly is also used to display the OPR value, which represents the redox potential of the electrolyte solution.

[0047] In some embodiments, the display end of the display component 6 extends out of the top of the fixed shaft 11, and the end cap is provided with a second through hole 802 for the visible display component.

[0048] In other embodiments, a fixing seat 7 is provided at the top of the fixing shaft 11, and a fixing cavity 701 is formed on one side of the fixing seat 7. The fixing seat 7, the inner cavity of the fixing shaft 11, and the purification body 1 form a closed chamber 101, and the display component 6 is installed in the fixing cavity 701. Furthermore, the display end of the fixing cavity 701 is made of a visible material.

[0049] Thus, the circuitry of the display component 6 is located within the enclosed cavity 101, and at least a portion of the display component 6 is located within the enclosed cavity 101. That is, the display end of the display cavity can be designed to be open. The display component 6 is embedded in the fixed cavity 701, with the display end of the display component 6 facing outwards for the user to view. In other words, the digital display end (display end) of the display component 6 extends out of the display end of the fixed cavity 701. It is only necessary to seal the connection between the display component 6 and the fixed cavity 701.

[0050] In some embodiments, an end cap 8 is detachably mounted on the top of the fixed shaft 11 or on the fixed base 7. The end cap 8 and the top of the fixed shaft 11 or the fixed base 7 form a purification chamber. The end cap 8 is provided with a first through hole 801. A purification component 4 is provided inside the purification chamber and is connected to the control main board 3. The first through hole 801 serves as a channel connecting the inside and outside of the purification chamber.

[0051] The end cap 8 can be detachably installed on the top of the fixed shaft 11 or on the fixed seat 7 by any of the following methods: snap-fit, screw-on, threaded connection, or screw connection.

[0052] The spoiler 5 is arranged around the fixed shaft 11. During the rotation of the spoiler 5, the end cover 8 does not come into contact with the spoiler 5, that is, there is a certain gap between the spoiler 5 and the end cover 8, and they are set apart. There is no friction noise between the spoiler 5 and the end cover 8, which solves the problem of high noise in the existing method of the end cover and the spoiler 5 abutting each other, and greatly improves the user experience.

[0053] Furthermore, the purification component 4 is an electrode assembly, including at least two spaced-apart electrode sheets. The electrode sheets have a ring-shaped or mesh-like structure. The electrode sheets located in the clearance space adopt a ring-shaped structure design and can be stacked vertically. This embodiment does not limit the fixing method of the electrode sheets. The principle of electrolysis to generate ozone and hydroxyl groups is existing technology.

[0054] The first and second electrolysis modules of the purification component 4 are both electrode plate components. When the fruit and vegetable machine is put into water, the first electrolysis module electrolyzes to generate ozone, and the electrode plate components of the second electrolysis module ionize water to generate hydrogen ions and hydroxide ions, forming hydroxyl radicals. The strong oxidizing power of hydroxyl radicals can kill bacteria and remove pesticide residues, thereby achieving the cleaning and purification of fruits and vegetables.

[0055] Furthermore, the end cap 8 is also provided with a second through hole 802, and the display end of the display component 6 is located in the second through hole 802.

[0056] In some implementations, the control motherboard 3 is equipped with a communication module, through which the control motherboard 3 sends the TOC value and COD value to the user terminal.

[0057] Through the communication module, users can view the changes in TOC and COD values ​​of the water before and after the fruit and vegetable purifier has been working online. Users can view the TOC and COD value test results without removing the purifier from the water. The system can provide users with TOC and COD value trends in the form of charts and graphs. Combined with the display component 6 on the main purification unit 1, it enables both online and offline visualization of TOC and COD values, enhancing the user experience.

[0058] This communication module can be implemented using various technologies such as Bluetooth, WIFI, home networking, local area network, and wide area network, enabling both remote and local online display of TOC and COD values.

[0059] Furthermore, the display component 6 is provided with a first display module and a second display module. The first display module is used to display the real-time TOC value and COD value detected by the probe component 9, and the second display module is used to display the initial TOC value and COD value.

[0060] The purification body 1 is designed with a flow-dispersing component 5. The flow-dispersing component 5 is driven to rotate by the drive component 2 to accelerate the water flow, so that the substances generated by the purification component 4 for purifying fruits and vegetables can quickly diffuse in the water, resulting in a better purification effect. The positioning part 501 and the limiting part 111 restrict the flow-dispersing component 5 from the fixed shaft 11 of the purification body 1. The positioning part 501 and the limiting part 111 work together to allow the flow-dispersing component 5 to be detachably set around the fixed shaft 11, which also facilitates the maintenance of components such as the probe component 9 and the flow-dispersing component 5.

[0061] Specifically, the positioning part 501 and the limiting part 111 adopt a concave-convex fitting method. The positioning part 501 is provided in the inner circumference of the baffle 5, and the limiting part 111 is concave-convex fitted with the contour of the limiting part 111 on the fixed shaft 11. After the baffle 5 and the fixed shaft 11 are assembled, the positioning part 501 is located below the limiting part 111, and the positioning part 501 and the limiting part 111 are offset from each other. The drive assembly 2 drives the baffle 5 to rotate, and the positioning part 501 and the limiting plate remain offset, that is, the positioning part 501 and the limiting part 111 do not align, and the baffle 5 does not detach from the fixed shaft 11 of the purification body 1. When disassembling and installing the baffle 5 and the fixed shaft 11 of the purification body 1, the positioning part 501 and the limiting part 111 are aligned, so that the baffle 5 can be easily separated and assembled from the fixed shaft 11.

[0062] Furthermore, a limiting part 111 is formed by a radial protrusion on the outer wall of the fixed shaft 11, and a positioning part 501 that is adapted to the limiting part 111 is formed by the upper and lower edges of the inner ring edge of the spoiler 5. When the spoiler 5 rotates, the positioning part 501 is located below the limiting part 111, and the positioning part 501 is misaligned with the limiting part 111. The end cover 8 is separated from the spoiler 5. When the spoiler 5 is disassembled or assembled, the positioning part 501 is connected to the limiting part 111.

[0063] The contours of the positioning part 501 and the limiting part 111 are adapted to each other. When the positioning part 501 and the limiting part 111 are connected, the baffle 5 can be installed by being fitted downward from the top of the fixed shaft 11 onto the fixed shaft 11. The baffle 5 can also be disassembled by moving upward from the bottom of the fixed shaft 11. At the same time, after the baffle 5 is assembled and installed with the fixed shaft 11 of the purification body 1, the positioning part 501 is located below the limiting part 111, and the positioning part 501 and the limiting part 111 are misaligned. During the rotation of the baffle 5, the limiting part 111 cannot be connected with the positioning part 501, ensuring that the baffle 5 does not detach from the fixed shaft 11. The friction between the baffle 5 and the fixed shaft 11 is small, which improves the rotation efficiency of the drive assembly 2 and greatly reduces noise. The baffle 5 does not contact the end cover 8 during the rotation, i.e., it is set separately, which solves the problem of high noise in the existing method of the end cover and the baffle 5 abutting each other, and greatly improves the user experience.

[0064] Furthermore, another concave-convex adaptation method between the positioning part 501 and the limiting part 111 is as follows: the outer wall edge of the fixed shaft 11 is formed by the vertically extending limiting part 111, the inner ring edge of the spoiler 5 protrudes towards the center to form the positioning part 501 that is adapted to the limiting part 111, the fixed shaft 11 is shaped with a larger upper part and a smaller lower part, when the spoiler 5 rotates, the positioning part 501 is located below the limiting part 111, the positioning part 501 and the limiting part 111 are misaligned, the end cap 8 is separated from the spoiler 5, and when the spoiler 5 is disassembled and assembled, the positioning part 501 and the limiting part 111 are connected.

[0065] The limiting part 111 protrudes slightly from the outer periphery of the fixed shaft 11. The limiting part 111 has a small overall volume, a small extension width along the axial direction of the fixed shaft 11, and a small extension thickness along the radial direction of the fixed shaft 11. This ensures that after the positioning part 501 is aligned with the limiting part 111, the turbulence member 5 can slide into the fixed shaft 11 from the top end to complete the installation of the turbulence member 5 and the purification body 1. Alternatively, it can slide out from the lower end of the fixed shaft 11 to complete the separation of the turbulence member 5 and the purification body 1. At the same time, it ensures that after the positioning part 501 and the limiting part 111 are misaligned, the turbulence member 5 will not detach from the fixed shaft 11 during rotation under the drive of the drive assembly 2, and the turbulence member 5 will not come into contact with or rub against the end cap 8.

[0066] In some embodiments, the drive assembly 2 includes a drive element 201, an output shaft, and a transmission gear 202. A rack 502 is circumferentially mounted on the outer periphery of the deflector 5. The drive element 201 drives the output shaft to rotate. One end of the output shaft extends out of the sealed chamber and is fitted with the transmission gear 202, which meshes with the rack 502. The drive element 201 can be a motor.

[0067] The electrode plate located in the clearance space has clearance parts to avoid the probe assembly and transmission structure (output shaft, transmission gear), such as the electrode plate adopting a ring structure with one end open.

[0068] This embodiment also includes a power supply component, which is located in the enclosed chamber 101. The power supply component is existing technology and will not be described in detail here.

[0069] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
