[0055] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0056] See Figures 1-16 This food cleaning equipment with TDS and temperature / humidity detection includes an electrical control mechanism, a main body 1, and a purification tank 2. The inner side of the purification tank 2 has a purification chamber 21 for placing food. The purification tank 2 has an installation cavity 23. The installation cavity 23 contains a purification device 3 that can generate a purification medium to the purification chamber 21. The purification device 3 is electrically connected to the electrical control mechanism. The installation cavity 23 contains a water quality detection device, which is a TDS detection head 28. The head of the TDS detection head 28 is located inside the installation cavity 23, and the tail of the TDS detection head 28 extends outward and is electrically connected to the electrical control mechanism through a wire. The outer side of the purification tank 2 is connected to a temperature detection unit 29, which is electrically connected to the electrical control mechanism.

[0057] The TDS detection head 28 can detect the water quality within the installation cavity 23 and also provide feedback on the water quality status to the user through an information interaction mechanism (such as a display screen). TDS measurement is primarily based on the conductivity method. Dissolved ions in water (such as Ca²⁺ and Mg²⁺) enhance the water's conductivity. After detecting the conductivity through electrodes, the instrument converts it into a TDS value. The specific principle of TDS detection is existing technology and can be understood by those skilled in the art.

[0058] The temperature detection unit 29 can also provide feedback on the water temperature in the purified water tank 2 to the user through an information interaction mechanism (such as a display screen), so that the user can understand the water temperature status in the purified water tank 2.

[0059] The TDS detector 28 and temperature detector 29 work together to monitor the water quality and temperature in the purification tank 2 in real time, enriching the equipment's functions. The electrical control mechanism can also adjust the working status of the purification device 3 based on the water quality and temperature data to meet the cleaning needs of different ingredients.

[0060] In actual use, when the water quality is relatively poor, the electronic control mechanism can increase the power of the purification device 3 to speed up the purification efficiency. When the water temperature is relatively low (such as when purifying frozen food), the electronic control mechanism can adjust the power of the purification device according to the water temperature change based on preset data, thereby achieving a relatively better purification and energy-saving effect.

[0061] Furthermore, an electrical cavity 11 is formed between the outer side of the purification tank 2 and the main body 1. The electrical cavity 11 is equipped with a power supply mechanism 4 and an air pump device 5. The placement of the power supply mechanism 4 and the air pump device 5 in the power supply cavity can make the installation structure of the two with the main body 1 more compact.

[0062] The power supply mechanism 4 is electrically connected to the air pump device 5 and the purification device 3 respectively. The air pump device 5 is connected to a jet nozzle 51 that can supply air to the purification chamber 21. The jet nozzle 51 is located inside the purification chamber 21. The direction in which the purification medium generated by the purification device 3 enters the purification chamber 21 and the direction in which the gas generated by the jet nozzle 51 enters the purification chamber 21 converges inside the purification chamber 21. The gas generated by the air pump device 5 can quickly disperse the relatively concentrated purification medium, allowing the purification medium to diffuse more quickly inside the purification chamber 21. Food in different positions inside the purification chamber 21 can come into more full contact with the purification medium. The bubbles generated by the jet nozzle 51 can cause the water in the purification chamber 21 to tumble rapidly to balance the concentration of the purification medium. At the same time, the bubbles can also have a good cleaning function for small particles on the surface of food, improving the food purification effect of the food purifier. Meanwhile, the power supply mechanism 4 can synchronously control the air pump device 5 and the purification device 3, thereby further improving the effect of the air pump device 5 and the purification device 3 in producing a rapidly diffused purification medium.

[0063] An air guide pipe 53 is provided between the air pump device 5 and the jet component 51. The first and last ends of the air guide pipe 53 are connected to the air pump device 5 and the jet component 51, respectively. There is a rotating shaft between the tail end of the air guide pipe 53 and the air inlet end of the jet component 51. The jet component 51 can rotate relative to the air guide pipe 53 around the rotating shaft. When it is necessary to clean the bottom of the purification chamber 21, the jet component 51 can be swung to make it stand up, making the bottom cleaning action of the purification chamber 21 more convenient.

[0064] Furthermore, the purification device 3 is located on the horizontal side wall of the purification chamber 21, and the jet 51 is located at the bottom of the purification chamber 21. The gas generated by the jet 51 can move vertically upward under the action of buoyancy. The upward movement of the gas can disperse the purification medium, allowing the purification medium to diffuse more quickly within the purification chamber 21.

[0065] Furthermore, the jet component 51 is plate-shaped, and its overall thickness is relatively thin, which can relatively reduce the space occupied by the jet component 51 in the purification chamber 21.

[0066] The jet component 51 has several air outlet holes 511, which can make the air bubbles more evenly distributed in the purification chamber 21, and further improve the diffusion efficiency of the purification medium.

[0067] Furthermore, the air outlet 511 is located at the bottom of the jet component 51, and the bottom of the jet component 51 is also provided with a support foot 512. The positions of the air outlet 511 and the support foot 512 are staggered. The support foot 512 extends downward and abuts against the bottom of the purification chamber 21, so that the air outlet 511 and the bottom of the purification chamber 21 form a gap. The air outlet 511 is located at the bottom of the jet component 51, which can reduce the chance of food residue clogging the air outlet 511. At the same time, the supporting rib 512 can not only allow the gas to be smoothly lifted upward after being discharged from the air outlet 511, but also improve the structural strength of the jet component 51.

[0068] Furthermore, a support plate 52 is provided in the purification chamber 21 above the jet nozzle 51. The support plate 52 has a support portion 521 that extends downward and abuts against the bottom of the purification chamber 21. Several exhaust holes 522 are distributed on the support plate 52. The support plate 52 can prevent food from pressing directly on the jet nozzle 51 and protect the jet nozzle 51. At the same time, the support plate 52 can have a certain aggregation effect on the bubbles. Some bubbles will be first gathered by the support plate 52 and then move upward through the exhaust holes 522, making the distribution of bubbles in the purification chamber 21 more uniform.

[0069] Furthermore, the support portion 521 has a bent edge shape and is distributed circumferentially along the bottom of the support plate 52. The support portion 521 is provided with a relief notch 523 corresponding to the jet component 51. The support portion 521 can reduce the chance of bubbles emerging from the periphery of the support plate 52, allowing the bubbles to be discharged better from the exhaust hole 522. The relief notch 523 makes the connection structure between the support portion 521 and the jet component 51 more compact.

[0070] Furthermore, the support plate 52 is detachable from the jet component 51 and the purification chamber 21, which facilitates cleaning and maintenance of the support plate 52 and the jet component 51.

[0071] Furthermore, the air pump device 5 is located below the purification tank 2, making better use of the space below the purification tank 21.

[0072] The air duct 53 is shaped like a "Z". The air duct 53 extends from bottom to top to the top of the purification chamber 21 and then extends downward through a bend to the bottom of the purification chamber 21 to connect with the jet component 51. When water in the purification chamber 21 flows back into the air duct 53, since the middle section of the air duct 53 is higher than the purification chamber 21, the water flowing back into the air duct 53 will not flow to the highest position of the middle section of the air duct 53, thereby preventing the water from flowing back to the air pump device 5 and protecting the air pump device 5.

[0073] Furthermore, a sealing element 54 is provided between the tail end of the air duct 53 and the air inlet end of the jet component 51 and / or the purified water tank 2. The sealing element 54 can ensure good sealing between the air duct 53, the jet component 51 and the purified water tank 2, and prevent water leakage.

[0074] Furthermore, the power supply mechanism 4 includes a power supply housing 41 and a power supply device (not shown in the figure) and a control board 42 disposed inside the power supply housing 41. The power supply device is electrically connected to the control board 42. An outer frame 43 is provided on the outside of the power supply device. The two ends of the outer frame 43 are open. A cooling fan (not shown in the figure) is provided on the front side of the power supply housing 41. The outer frame 43 enables the airflow generated by the cooling fan to act more concentratedly on the power supply device, which can better achieve the effect of heat dissipation and cooling of the power supply device.

[0075] The first and last ends of the outer frame 43 are spaced apart from the cooling fan and the rear side of the power box shell 41, respectively. The control board 42 is located on the outside of the outer frame 43 and is offset from the openings at both ends of the outer frame 43. Since the heat generated by the control board 42 is relatively small, part of the airflow generated by the cooling fan can flow to the control board 42 through the position between the first and last ends of the outer frame 43 and the power box shell 41. This can not only provide a certain cooling effect for the control board 42, but also eliminate the need to install an additional cooling fan for the control board 42, thereby reducing material costs.

[0076] The cooling fan can simultaneously cool the power supply unit and the control board 42, reducing the chance of high-temperature failures caused by prolonged use and improving the stability of the equipment.

[0077] Furthermore, the bottom of the outer frame 43 and / or control board 42 is provided with a foot 44, which creates a gap between the bottom of the outer frame 43 and / or control board 42 and the inner bottom of the power supply box housing 41. The foot 44 allows airflow to flow between the bottom of the control board 42 and the inner bottom of the power supply box housing 41, further improving the heat dissipation and cooling effect of the power supply device and the control board 42.

[0078] Furthermore, the power box housing 41 includes a power box base 411 and a power box top cover 412. The power box base 411 has first side plates 4111 on both ends, and the power box top cover 412 has second side plates 4121 on both sides. The first side plates 4111 and the second side plates 4121 are connected and cooperate with the power box top cover 412 and the power box base 411, respectively. The first side plates 4111 and the second side plates 4121 are connected end to end along the circumference of the power box housing 41. The power box base 411 and the power box top cover 412 can be quickly assembled to form the power box housing 41. In actual assembly, the power supply device and control board 42 and other components can be assembled in the power box base 411 first, and then the power box top cover 412 is assembled last, which simplifies the assembly process.

[0079] Furthermore, the first side plate 4111 is provided with snap-fit ​​grooves 4112 on the left and right sides, and the second side plate 4121 is provided with snap-fit ​​ribs 4122 corresponding to the snap-fit ​​grooves 4112. The upper side of the snap-fit ​​grooves 4112 is open. The power box base 411 and the power box cover 412 are connected and fixed or detachable so that the snap-fit ​​ribs 4122 can enter or leave the snap-fit ​​grooves 4112 from the opening on the upper side of the snap-fit ​​grooves 4112, which can improve the stability of the connection structure between the power box base 411 and the power box cover 412.

[0080] Furthermore, the upper side of the first side plate 4111 is provided with a first flange 4113, the power box cover 412 abuts against the first flange 4113, the first flange 4113 is provided with a positioning hole 4114, the power box cover 412 is provided with a positioning rib 4123 corresponding to the positioning hole 4114, the power box base 411 and the power box cover 412 are connected and fixed or can be detached so that the positioning rib 4123 can be inserted and engaged with the positioning hole 4114 or separated from each other, which can further improve the connection accuracy and stability of the connection structure between the power box base and the power box cover 412.

[0081] Furthermore, the power box base 411 is provided with second flanges 4115 on the left and right sides. The second flanges 4115 are connected and fixed to the second side plate 4121 by screws. The second flanges 4115 can increase the contact area between the power box base 411 and the power box cover 412, making the connection structure between the two more stable, and at the same time, it is easier to lock and fix the two by screws.

[0082] Furthermore, the power box housing 41 is located at the bottom of the electrical cavity 11, corresponding to the position below the purified water tank 2. The bottom of the power box housing 41 is provided with a support mechanism, which creates a gap between the bottom of the power box housing 41 and the inner bottom of the electrical cavity 11, thereby reducing the chance of water accumulation coming into contact with the power box housing 41 and improving the safety of the equipment.

[0083] Furthermore, the support mechanism includes several first support legs 451 and second support legs 452. The first support legs 451 are columnar and distributed at the four bottom corners of the power box housing 41. The second support legs 452 are zigzag-shaped and distributed between two adjacent first support legs 451. The first support legs 451 can provide the main support for the power box housing 41 as a whole, while the second support legs 452 can provide support for the middle position of the power box housing 41, further improving the stability of the support mechanism in supporting the power box housing 41 as a whole.

[0084] Furthermore, the purification tank 2 is connected to a drain pipe 22, and the bottom of the electrical cavity 11 is provided with a drain hole 12 corresponding to the drain pipe 22. The drain pipe 22 extends outward through the drain hole 12 and can guide the water flow outward.

[0085] Furthermore, the diameter of the drain hole 12 is larger than the diameter of the drain pipe 22, and a drainage space is formed between the outer side of the drain pipe 22 and the drain hole 12. In addition to allowing the drain pipe 22 to extend outward, the drain hole 12 can also allow water to be discharged outward when water accumulates in the electrical cavity 11, reducing the chance of water accumulating in the electrical cavity 11.

[0086] Furthermore, the purification device 3 is a water catalyst generator, which can remove harmful substances such as pesticide residues, bacteria, and viruses, ensuring food safety and improving the quality of ingredients.

[0087] The water catalyst generating device includes a first conductive strip 311 and a second conductive strip 312. The electrodes of the first conductive strip 311 and the second conductive strip 312 are opposite. A plurality of first electrode plates 321 are distributed on the first conductive strip 311, and a plurality of second electrode plates 322 are distributed on the second conductive strip 312. The first electrode plates 321 and the second electrode plates 322 are alternately distributed, and a gap is formed between adjacent first electrode plates 321 and second electrode plates 322.

[0088] The first conductive strip 311 and the first electrode plate 321 are installed and positioned by corresponding limiting mechanisms and fixed by welding. The limiting mechanism can play the role of installation and positioning of the first conductive strip 311 and the first electrode plate 321, and then the two are further fixed by welding.

[0089] The second conductive strip 312 and the second electrode plate 322 are installed and positioned by corresponding limiting mechanisms and fixed by welding. The limiting mechanism can play the role of installation and positioning of the second conductive strip 312 and the second electrode plate 322, and then the two are further fixed by welding.

[0090] By using a limiting mechanism and welding fixation, the connection strength between the first conductive strip 311 and the first electrode plate 321, and between the second conductive strip 312 and the second electrode plate 322, can be improved, avoiding poor contact caused by corrosion and other reasons between the first conductive strip 311 and the first electrode plate 321, and between the second conductive strip 312 and the second electrode plate 322, thereby improving the overall stability of the water catalyst generator.

[0091] Furthermore, the limiting mechanism includes a conductive strip recess 313 and an electrode plate recess 323. The conductive strip recess 313 is disposed on the first conductive strip 311 and the second conductive strip 312, and the electrode plate recess 323 is disposed on the first electrode plate 321 and the second electrode plate 322. The first electrode plate 321 and the second electrode plate 322 are perpendicular to each other, and the conductive strip recess 313 and the electrode plate recess 323 are interlocked. The cooperation between the conductive strip recess 313 and the electrode plate recess 323 can improve the installation accuracy between the first conductive strip 311 and the first electrode plate 321 and the second conductive strip 312 and the second electrode plate 322, and can also enable the first conductive strip 311 and the first electrode plate 321 and the second conductive strip 312 and the second electrode plate 322 to be pre-installed quickly, thereby improving the efficiency of subsequent welding.

[0092] Furthermore, the water catalyst generating device also includes an insulating frame 33, which is provided with a plurality of positioning grooves 332. The positioning grooves 332 at the same horizontal height are connected and cooperate with each first electrode plate 321 and second electrode plate 322 in a one-to-one correspondence, thereby further improving the stability of the installation structure of the first electrode plate 321 and the second electrode plate 322 and avoiding direct contact between the first electrode plate 321 and the second electrode plate 322 to prevent short circuit faults.

[0093] Furthermore, the insulating frame 33 has several sets of positioning grooves distributed vertically. Each positioning groove consists of several positioning grooves 332 distributed at the same horizontal height, which makes the structure of the first electrode plate 321 and the second electrode plate 322 more stable at different vertical positions and less prone to positional displacement. This further avoids direct contact between the first electrode plate 321 and the second electrode plate 322, which could lead to a short circuit.

[0094] Furthermore, the insulating frame 33 is frame-shaped and is connected to a cover plate 34. The cover plate 34, together with the insulating frame 33, can protect the first conductive strip 311, the first electrode plate 321, the second conductive strip 312, and the second electrode plate 322.

[0095] The cover plate 34 and the insulating frame 33 are detachable and can be fixed together by a snap-fit ​​mechanism. The cover plate 34 is provided with a positioning rib 341 on the inner side of the insulating frame 33. The positioning rib 341 is tightly fitted with the inner wall of the insulating frame 33. The positioning rib 341 can improve the installation accuracy and connection strength of the cover plate 34 and the insulating frame 33.

[0096] Furthermore, the insulating frame 33 is connected and fixed to the first conductive strip 311 and the second conductive strip 312 respectively by screw devices. The insulating frame 33 is provided with positioning protrusions 331, and the first conductive strip 311 and the second conductive strip 312 are respectively provided with corresponding positioning holes 314. The positioning protrusions 331 and the positioning holes 314 are inserted and engaged. The insulating frame 33 can also play the role of installation positioning for the first conductive strip 311 and the second conductive strip 312, making the installation structure between the first conductive strip 311 and the second conductive strip 312 more stable.

[0097] Furthermore, the first conductive strip 311 and the second conductive strip 312 are respectively connected to corresponding terminal assemblies. The terminal assembly includes a terminal body 37 and a locking nut 35. The first end of the terminal body 37 is located inside the purification water tank 2 and is connected and fixed to the corresponding first conductive strip 311 or second conductive strip 312. The end of the terminal body 37 extends outward through the purification water tank 2. The locking nut 35 is connected and fixed to the end of the terminal body 37 so that the terminal body 37 is fixedly installed on the purification water tank 2. A sealing ring 36 is tightly connected between the inner and / or outer sides of the purification water tank 2 and the terminal body 37, which facilitates the electrical connection between the water catalyst generator and the external power supply equipment, and at the same time improves the sealing performance between the purification water tank 2 and the terminal assembly, making the equipment safer to operate.

[0098] Furthermore, the purification tank 2 is provided with an installation cavity 23. The inner and outer sides of the purification tank 2 corresponding to the installation cavity 23 are respectively concave and convex. The water catalyst generator is located inside the installation cavity 23. The side of the installation cavity 23 facing the purification cavity 21 is open. A baffle 24 is fixedly connected to the opening of the installation cavity 23. Several through holes 241 are distributed on the baffle 24, which relatively increases the volume of the purification cavity 21 and increases the capacity for purifying food. The baffle 24 can block relatively large impurities and prevent relatively large impurities from directly contacting the water catalyst generator.

[0099] Furthermore, an outer protective frame 25 is fixedly connected inside the mounting cavity 23. The outer protective frame 25 is provided with a connecting flange 251, which is connected and fixed to the baffle 24. The baffle 24 and the outer protective frame 25 form a cavity that can accommodate the water catalyst generator, which can further protect the water catalyst generator and further improve the stability of the connection structure of the baffle 24.

[0100] Furthermore, a platform 26 is provided on the upper side of the purification tank 2, and a boss 27 is provided on the platform 26 corresponding to the rear position of the purification tank 2. An inclined surface 271 is provided on the front side of the boss 27. The inclined surface 271 is inclined from top to bottom towards the front. A display panel 6 that can provide feedback information to the user is provided on the inclined surface 271. The display panel 6 is electrically connected to the power supply mechanism 4, which can reduce the chance of liquid splashing onto the display panel 6 during use, making the display panel 6 less prone to failure. The display panel 6 can also be a panel with touch control function.
