Technical Field

[0001] The present invention relates to the field of food purification devices, in particular to a purification device and food purification equipment. Background Art

[0002] There will be residual pollutants such as pesticides, hormones, dust and germs on the surface of fruit and vegetable products. If the fruit and vegetable products are not cleaned properly before being eaten, it will affect people's health. Therefore, food cleaning devices for cleaning fruit and vegetable products have appeared on the market. Common food cleaning devices include a sink and a purification device. The purification device includes a shell, a purification module and a water driving device. The purification module is arranged on the shell, and the rear terminal of the purification module passes through the side wall of the shell and is connected to the external power supply. The water driving device is used to drive the water in the sink to flow through the purification module; a water outlet is arranged on the inner wall of the sink, and the shell is arranged on the outside of the sink, and the opening of the shell is sealed and connected with the water outlet through a sealing ring; the purification device of this type of food cleaning device is large in size, complex in structure, difficult to assemble, and not easy to disassemble and clean. In addition, the shell, the purification module terminal and the sink all rely on the sealing ring for sealing, and there are strict requirements on the selection of the sealing ring, resulting in high production costs. At the same time, the sealing ring ages after long-term use, and the leak-proof effect decreases, which easily causes the water in the sink to seep out from the connection between the purification device and the sink. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a purification device with a simple structure that is easy to assemble and disassemble. After the purification device is installed in the water tank, the water in the water tank cannot seep out from the connection between the purification device and the water tank, and the water leakage prevention effect is good.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a purification device, comprising a shell, a water catalyst mechanism and a baffle; the shell is provided with a purification chamber, and the purification chamber is provided with a front opening; the water catalyst mechanism is installed in the purification chamber, and it comprises an electrode unit, a first electrode terminal and a second electrode terminal, the electrode unit is composed of a plurality of first electrode pieces and second electrode pieces arranged alternately, the first electrode terminal and the second electrode terminal are arranged at the upper part of the electrode unit, each first electrode piece is connected to the first electrode terminal, each second electrode piece is connected to the second electrode terminal, a catalytic zone is formed between adjacent first electrode pieces and second electrode pieces, and the ends of the first electrode terminal and the second electrode terminal extend out of the upper part of the shell; the baffle is detachably arranged on the front side of the shell, and is provided with a mesh hole connected to the front opening of the purification chamber.

[0005] Compared with the prior art, the purification device of the present invention has the following beneficial effects:

[0006] (1) The purification device of the present invention is composed of three main components, namely, a housing, a water catalyst mechanism and a cover. The number of components is small, thereby reducing production costs and facilitating component production and assembly of the entire device. In addition, since pollutants will adhere to the surface of the water catalyst mechanism after long-term use, reducing the purification effect of the purification device, the small number of components of the purification device makes it easier for users to disassemble the purification device and clean the water catalyst mechanism separately, thereby ensuring the purification effect of the purification device and extending the service life of the water catalyst mechanism.

[0007] (2) The purification device of the present invention has a simple structure, which makes it easy for production personnel to make full use of the internal space of the purification device and arrange the components in the purification device more tightly, thereby effectively reducing the volume of the purification device. On the one hand, it can reduce the storage space required for transporting the purification device and effectively reduce the transportation cost. On the other hand, it can reduce the space required for installing the food purification equipment equipped with the purification device, reduce the space requirement for installing the food purification equipment, and facilitate users to install the food purification equipment.

[0008] (3) The water catalyst mechanism of the present invention is connected to an external power source by passing through the first electrode terminal and the second electrode terminal extending out of the upper part of the shell. By extending the end of the water catalyst mechanism connected to the external power source out of the upper part of the shell, it is avoided to open a hole in the middle or lower part of the side wall of the water tank. After the water in the water tank soaks in the purification device, the water will not seep out, thereby improving the sealing and safety performance of the purification device, and improving the aesthetics of the purification device.

[0009] Preferably, the first pole piece and the second pole piece are arranged vertically; the upper end of each first pole piece is fixedly connected in parallel through a first power connection plate, and the lower end of the first electrode terminal is connected to the first power connection plate; the upper end of each second pole piece is fixedly connected in parallel through a second power connection plate, and the lower end of the second electrode terminal is connected to the second power connection plate.

[0010] The above-mentioned arrangement integrates a plurality of first pole pieces, the lower end of the first electrode terminal and the first power connection plate, and a plurality of second pole pieces, the lower end of the second electrode terminal and the second power connection plate into an integral component, thereby simplifying the structure of the electrode unit and reducing the volume of the electrode unit, making it easier for production personnel to design a smaller purification device. In addition, this arrangement can facilitate installation by production personnel, increase the speed of assembling the water catalyst mechanism, and thus improve production efficiency.

[0011] Preferably, a first rear step is provided on the rear side of the upper end of the first pole piece, and the first power connection plate is installed on the front side of the upper end of the first pole piece; a second front step is provided on the front side of the upper end of the second pole piece, and the second power connection plate is installed on the rear side of the upper end of the second pole piece; when the first pole piece and the second pole piece are combined, the first power connection plate is located on the upper side of the second front step, and the second power connection plate is located on the upper side of the first rear step.

[0012] The above-mentioned arrangement of the first pole piece and the second pole piece has the following beneficial effects: through the first rear step of the first pole piece, the second front step on the second pole piece can play a role in avoiding the first power connection plate and the second power connection plate, so that the arrangement of parts in the purification device is more compact. In addition, this arrangement can reduce the materials required for the production of electrode units, thereby reducing the production cost of electrode units.

[0013] Preferably, the bottom wall of the purification chamber is provided with a plurality of lower positioning grooves corresponding to the first electrode piece and the second electrode piece, and the top wall of the purification chamber is provided with upper positioning grooves corresponding to the first electrode terminal and the second electrode terminal, the lower ends of the first electrode piece and the second electrode piece are clamped in the corresponding lower positioning grooves, and the first electrode terminal and the second electrode terminal are arranged in the corresponding upper positioning grooves.

[0014] By providing a lower positioning groove and an upper positioning groove, the upper and lower parts of the water catalyst mechanism are fixed, which makes it easier for production personnel to install the water catalyst mechanism in the purification room, improves the assembly speed, and shortens the production time. In addition, by fixing the upper and lower parts of the water catalyst mechanism, it is possible to avoid displacement or even damage of the electrode unit during transportation and installation (installation in food purification equipment) of the purification device, resulting in a decrease in the purification effect of the purification device, and to avoid adjacent plates from shifting and contacting under the impact of water flow, which would make the purification device unable to be used normally.

[0015] Preferably, it also includes a connecting component for connecting the first electrode terminal and the second electrode terminal to the sink; the shell is provided with a through hole for the first electrode terminal and the second electrode terminal to pass through; the connecting component includes a fixing kit and a fixing part, the fixing kit is arranged at the rear side of the through hole, and the first electrode terminal and the second electrode terminal can pass through the corresponding through hole and the fixing kit in sequence; the fixing part is used to connect the fixing kit and the sink wall.

[0016] The connecting component has a simple structure, which can effectively reduce the difficulty of installing and disassembling the purification device, and is convenient for production personnel and users to install the purification device, as well as to disassemble the purification device for cleaning. The connecting component is stable and reliable, so that the purification device can be firmly fixed on the side wall of the water tank to prevent the purification device from shaking during operation. In addition, the connecting component is arranged at the position corresponding to the shell and the first electrode terminal and the second electrode terminal. On the one hand, when producing the shell, a through hole and a fixing kit for the first electrode terminal and the second electrode terminal to pass through can be simultaneously arranged, thereby reducing the processing steps and shortening the production time, and avoiding the setting of a fixing structure at other positions of the shell, so that the volume of the purification device can be designed to be smaller. On the other hand, since the connecting component is arranged on the upper part of the shell, it can prevent the water in the water tank from seeping out from the surrounding side of the connecting component, and the fixing kit can fix the first electrode terminal and the second electrode terminal and improve the structural strength.

[0017] Preferably, a photocatalyst mechanism is provided on one side of the shell, and the photocatalyst mechanism comprises a UV lamp, and the photocatalyst mechanism performs photocatalysis on the water in the catalytic zone after being energized.

[0018] The purification device of the present invention is provided with a photocatalyst mechanism, which has the following beneficial effects: since the water body will bend in energy band after being irradiated by light, and the water body will undergo a decomposition reaction (H 21 =H + +0H - ), the present invention realizes the combination of electrocatalysis and photocatalysis by simultaneously arranging a water catalyst mechanism and a photocatalyst mechanism, so that the water body can quickly generate hydroxyl free radicals under the joint action of the electrocatalysis and photocatalysis of the purification device, thereby improving the efficiency of the purification device in generating hydroxyl free radicals, making the hydroxyl free radicals in the water body increase exponentially, thereby improving the cleaning effect of the present invention on fruit and vegetable products and utensils. In addition, the purification device of the present invention can achieve the same cleaning effect in a shorter time than the existing food cleaning device, thereby saving electric energy and water resources.

[0019] Preferably, the housing is provided with a UV lamp slot with an opening at the front side, and the UV lamp is installed in the UV lamp slot.

[0020] By setting up a UV lamp trough and pre-setting an opening with a fixed direction in the UV lamp trough, it is convenient for production personnel to quickly install the photocatalyst mechanism, avoiding the photocatalyst mechanism from being improperly installed or shifting during use, which leads to a decrease in the photocatalytic effect. In addition, the UV lamp trough is arranged as a whole on the shell, which is convenient for production personnel to design the arrangement of parts in the shell in advance, so that the structure of the purification device can be designed to be more compact.

[0021] Preferably, the shell is provided with an air diffusion channel, the air diffusion channel is provided with an air vent for ventilating the catalytic zone, and the upper part of the shell is provided with an air supply interface connected to the air diffusion channel for connecting to an air supply source.

[0022] When the purification device is working, the air supply source supplies gas from the air supply interface to the air diffusion channel and sprays it out from the vent. The sprayed gas and water form a surge and flow toward the upper part of the shell, thereby promoting the flow of water in the purification room.

[0023] The above arrangement of using the gas discharged from the gas diffusion channel to drive the water flow in the purification chamber has the following advantages:

[0024] (1) By controlling the airflow direction and airflow speed of the gas discharged from the diffuser channel, a mechanical boosting effect is generated on the circulation of water in the purification room, promoting the rapid circulation exchange between the purified water containing disinfectants in the purification room and the external water, and preventing the backflow of water, ensuring the directional flow of water, and improving the working efficiency of the purification device;

[0025] (2) The air diffusion channel is placed as a whole in the purification room, which can make the internal structure of the purification device more compact, thereby reducing the space occupied by the purification device and facilitating the installation of the purification device;

[0026] (3) Using gas to drive the flow of water requires fewer parts, consumes less electricity, and is more efficient than other power sources, which can effectively reduce the production and operating costs of the purification device.

[0027] Another object of the present invention is to provide a food purification device using the above-mentioned purification device, which includes a water tank and a purification device, wherein a purification device installation groove is provided on the side wall of the water tank, the front side of the purification device installation groove is open, and the purification device is installed in the purification device installation groove.

[0028] Compared with the prior art, the food purification equipment of the present invention has the following beneficial effects:

[0029] (1) The food purification equipment of the present invention generates hydroxyl radicals by decomposing water. Hydroxyl radicals have a strong ability to obtain electrons and can react with organic matter (such as pesticide residues and hormones) to oxidize the organic matter into substances that are harmless to the human body, such as oxygen, carbon dioxide, water, mineral salts, etc. Therefore, the present invention has high safety, stable and reliable cleaning effect, and can fully meet the cleaning and disinfection needs of fruit and vegetable products and utensils in daily life;

[0030] (2) The food purification equipment of the present invention is composed of a water tank and a purification device. By providing a purification device installation slot in the water tank for installing the purification device, it is convenient for users to install the purification device and disassemble it for cleaning, thereby reducing the maintenance cost of the food purification equipment.

[0031] (3) The purification device of the present invention is installed in the purification device installation groove, so there is no need to set other sealing structures on the side wall of the water tank to cooperate with the purification device seal. On the one hand, it can effectively reduce the difficulty of processing the water tank and reduce production costs. On the other hand, it can effectively improve the sealing performance of the food purification equipment, prevent the water in the water tank from flowing out from the connection between the water tank and the purification device, and improve the safety of the food purification equipment.

[0032] Preferably, the water catalyst mechanism is arranged on one side of the purification chamber, and a rear opening is provided on the other side of the purification chamber. A water driving device is provided at a position corresponding to the rear opening of the purification chamber on the rear side of the purification device installation slot; when the purification device is installed in the purification device installation slot, the water driving device is located in the purification chamber.

[0033] By providing a water driving device, the water in the purification device can be exchanged with the external water, thereby increasing the water circulation speed and improving the purification efficiency of the food purification equipment. In addition, the water driving device can contact the external water through a baffle with mesh holes. When the purification device is placed in a water tank, the water driving device can drive the water in the water tank to flow quickly, thereby improving the cleaning effect of the water on the food.

DETAILED DESCRIPTION

[0055] The following describes the embodiments of the present invention in conjunction with the accompanying drawings:

[0056] Embodiment 1

[0058] See also Figure 8 The first pole piece 35 and the second pole piece 36 are arranged vertically; the upper end of each first pole piece 35 is fixedly connected in parallel through the first power connection plate 33, and the lower end of the first electrode terminal 31 is connected to the first power connection plate 33; the upper end of each second pole piece 36 is fixedly connected in parallel through the second power connection plate 34, and the lower end of the second electrode terminal 32 is connected to the second power connection plate 34.

[0059] The above-mentioned arrangement integrates a plurality of first pole pieces 35, the lower end of the first electrode terminal 31 and the first power board 33, and a plurality of second pole pieces 36, the lower end of the second electrode terminal 32 and the second power board 34 into an integral component, thereby simplifying the structure of the electrode unit and reducing the volume of the electrode unit, making it easier for production personnel to design the purification device 1 smaller. In addition, this arrangement can facilitate installation by production personnel, increase the speed of assembling the water catalyst mechanism 3, and thus improve production efficiency.

[0060] See also Figure 8 A first rear step 352 is provided on the rear side of the upper end of the first pole piece 35, and the first power connection plate 33 is installed on the front side of the upper end of the first pole piece 35; a second front step 362 is provided on the front side of the upper end of the second pole piece 36, and the second power connection plate 34 is installed on the rear side of the upper end of the second pole piece 36; when the first pole piece 35 and the second pole piece 36 are combined, the first power connection plate 33 is located on the upper side of the second front step 362, and the second power connection plate 34 is located on the upper side of the first rear step 352.

[0061] In this embodiment, a first protrusion 351 is provided in the middle of the upper end of the first pole piece 35 , and the first rear step 352 is formed behind the first protrusion 351 ; a second protrusion 361 is provided in the middle of the upper end of the second pole piece 36 , and the second front step 362 is formed in front of the second protrusion 361 .

[0062] The arrangement of the first pole piece 35 and the second pole piece 36 has the following beneficial effects: through the first rear step 352 of the first pole piece 35, the second front step 362 on the second pole piece 36 can play a role in avoiding the first power connection plate 33 and the second power connection plate 34, so that the arrangement of the components in the purification device 1 is more compact. In addition, this arrangement can reduce the materials required for the production of the electrode unit, thereby reducing the production cost of the electrode unit.

[0063] Specifically, the first electrode terminal 31 and the second electrode terminal 32 are connected to the positive electrode and the negative electrode of the external power source respectively, so that the first electrode piece 35 and the second electrode piece 36 are the cathode plate and the anode plate respectively, and the electron charge is transferred between the adjacent first electrode piece 35 (cathode plate) and the second electrode piece 36 (anode plate), and the water body will undergo a decomposition reaction (H 21 =H + +0H - ), quickly generating hydroxyl radicals; in this embodiment, the first electrode terminal 31 and the second electrode terminal 32 are bent. In another embodiment, the first electrode 35 is an anode plate, and the second electrode 36 is a cathode plate.

[0064] See also Figures 9 and 10 The bottom wall of the purification chamber 21 is provided with a plurality of lower positioning grooves 23 corresponding to the first electrode piece 35 and the second electrode piece 36. The purification chamber 21 is provided with a top wall 28 located above the electrode unit. The top wall 28 of the purification chamber 21 is provided with upper positioning grooves 24 corresponding to the first electrode terminal 31 and the second electrode terminal 32. The lower ends of the first electrode piece 35 and the second electrode piece 36 are clamped in the corresponding lower positioning grooves 23, and the first electrode terminal 31 and the second electrode terminal 32 are arranged in the corresponding upper positioning grooves 24.

[0065] By providing the lower positioning groove 23 and the upper positioning groove 24, the upper and lower parts of the water catalyst mechanism 3 are fixed, which makes it easier for production personnel to install the water catalyst mechanism 3 in the purification chamber 21, thereby increasing the assembly speed and shortening the production time. In addition, by fixing the upper and lower parts of the water catalyst mechanism 3, it is possible to avoid displacement or even damage of the electrode unit during the transportation and installation (installation in food purification equipment) of the purification device 1, thereby reducing the purification effect of the purification device 1, and to avoid displacement and contact between adjacent electrode plates under the impact of water flow, thereby preventing the purification device 1 from being used normally.

[0066] See also Figure 1 and Figure 7, and also includes a connecting component for connecting the first electrode terminal 31 and the second electrode terminal 32 to the water tank; the shell 2 is provided with a through hole 25 for the first electrode terminal 31 and the second electrode terminal 32 to pass through, and the inner wall of the water tank involved is provided with an electrode hole corresponding to the through hole 25 (not shown in the figure); the connecting component includes a fixing kit 27 and a fixing member (not shown in the figure), the fixing kit 27 is arranged on the side of the through hole 25 facing the electrode hole, and the first electrode terminal 31 and the second electrode terminal 32 can pass through the corresponding through hole 25 and the fixing kit 27 in sequence; the fixing member is used to connect the fixing kit 27 and the water tank wall, specifically, the fixing kit 27 is inserted into the electrode hole, and the fixing member is connected to the end of the fixing kit 27 inserted into the electrode hole, so that the fixing kit 27 is fixedly connected to the inner wall of the water tank.

[0067] Specifically, the fixing kit 27 is threadedly connected to the fixing piece. The fixing piece in this embodiment is a nut. The fixing kit 27 is integrally arranged with the shell 2. In order to avoid the tightness and waterproof performance between the electrode terminal and the via hole 25, a sealing ring 26 is provided in the via hole 25.

[0068] The connecting assembly has a simple structure, which can effectively reduce the difficulty of installing and disassembling the purification device 1, and is convenient for production personnel and users to install the purification device 1, and to disassemble the purification device 1 for cleaning. The connecting assembly is stable and reliable, so that the purification device 1 can be firmly fixed on the side wall of the water tank to prevent the purification device 1 from shaking during operation. In addition, the connecting assembly is arranged at the position corresponding to the shell 2 and the first electrode terminal 31 and the second electrode terminal 32. On the one hand, when the shell 2 is produced, a through hole 25 and a fixing kit 27 for the first electrode terminal 31 and the second electrode terminal 32 to pass through can be simultaneously arranged, thereby reducing the processing steps and shortening the production time, and avoiding the setting of a fixing structure at other positions of the shell 2, so that the volume of the purification device 1 can be designed to be smaller. On the other hand, since the connecting assembly is arranged on the upper part of the shell 2, it can prevent the water in the water tank from seeping out from the surrounding side of the connecting assembly, and the fixing kit 27 can fix the first electrode terminal 31 and the second electrode terminal 32 and improve the structural strength.

[0069] In order to reduce the production cost and weight of the purification device 1 and thereby ensure that the connection assembly can firmly fix the purification device 1 , a clearance hole 29 is provided on the housing 2 .

[0070] See also Figure 3 The shell 2 is provided with a gas diffusion channel 5, and the gas diffusion channel 5 is provided with a vent 51 for ventilating the catalytic zone 37. The upper part of the shell 2 is provided with a gas supply interface 52 connected to the gas diffusion channel 5 for connecting to a gas supply source.

[0071] When the purification device 1 is working, the gas supply source supplies gas from the gas supply interface 52 to the gas diffusion channel 5, and the gas is ejected from the vent 51. The ejected gas and water form a surge and flow toward the upper part of the shell 2, thereby promoting the flow of water in the purification chamber 21.

[0072] Specifically, the air diffusion channel 5 extends from the side of the purification chamber 21 to the lower part of the purification chamber 21 , and the vent 51 is arranged at the lower part of the purification chamber 21 .

[0073] The above arrangement of using the gas discharged from the gas diffusion channel 5 to drive the water flow in the purification chamber 21 has the following advantages:

[0074] (1) By controlling the airflow direction and airflow speed of the gas discharged from the air diffusion channel 5, a mechanical boosting effect is generated on the circulation of the water body in the purification chamber 21, thereby promoting the rapid circulation exchange between the purified water containing disinfectants in the purification chamber 21 and the external water body, and preventing the backflow of the water body, ensuring the directional flow of the water body, and improving the working efficiency of the purification device 1;

[0075] (2) The air diffusion channel 5 is placed as a whole in the purification chamber 21, which can make the internal structure of the purification device 1 more compact, thereby reducing the space occupied by the purification device 1 and facilitating the installation of the purification device 1;

[0076] (3) Using gas to drive the flow of water requires fewer parts, consumes less electricity, and has higher efficiency than other power sources, which can effectively reduce the production cost and operation cost of the purification device 1.

[0077] See also Figure 1 to Figure 2 Specifically, an interface kit 53 and a fixing part (not shown in the figure) are provided on the outside of the air supply interface 52. The interface kit 53 is fixedly arranged on the outside of the end of the air supply interface 52 penetrating the shell 2. The inner wall of the water tank is provided with an air supply through hole (not shown in the figure) corresponding to the interface kit 53. The interface kit 53 is inserted into the air supply through hole. The fixing part is connected to the end of the interface kit 53 inserted into the air supply through hole, so that the interface kit 53 is fixedly connected to the inner wall of the water tank. The interface kit 53 can fix the air supply interface 52 and improve the structural strength.

[0078] In order to ensure the best driving effect of the air diffusion channel 5 on the water body, the air vent 51 of the air diffusion channel 5 is set at the lower part of the purification chamber 21, and the air vent 51 is filled with air diffusion stones (not shown in the figure). The air diffusion stones can disperse the air mass discharged from the air diffusion channel 5 into uniform small bubbles, and the generation of a large number of small bubbles is conducive to the dispersion of the water body. After the water body is fully dispersed, it is conducive to the improvement of the catalytic decomposition efficiency of the purification device 1, thereby increasing the content of disinfectants in the water body; because the small bubbles rise more slowly than the large air mass, the air diffusion stones can prolong the flow time of the water body in the purification device 1, on the one hand, prolonging the contact time between the water body and the second pole piece 36 and the first pole piece 35, thereby increasing the content of disinfectants in the water body, and on the other hand, it can reduce the circulation speed of the water body between the outside world and the purification device 1, so that the water body containing disinfectants is fully in contact with the fruit and vegetable products in the outside world, and improve the cleaning effect of the present invention on fruit and vegetable products.

[0079] See also Figure 3 A photocatalyst mechanism (not shown in the figure) is provided on one side of the shell 2. The photocatalyst mechanism includes a UV lamp. When the photocatalyst mechanism is powered on, it performs photocatalysis on the water in the catalytic zone 37.

[0080] The purification device 1 of the present invention is provided with a photocatalyst mechanism, which has the following beneficial effects: since the water body will have energy band bending after being irradiated by light, and the water body will undergo a decomposition reaction after being energized (H 21 =H + +0H - ), the present invention realizes the combination of electrocatalysis and photocatalysis by simultaneously setting a water catalyst mechanism 3 and a photocatalyst mechanism, so that the water body can quickly generate hydroxyl free radicals under the joint action of the electrocatalysis and photocatalysis of the purification device 1, thereby improving the efficiency of the purification device 1 in generating hydroxyl free radicals, making the hydroxyl free radicals in the water body increase exponentially, thereby improving the cleaning effect of the present invention on fruit and vegetable products and utensils. In addition, the purification device 1 of the present invention can achieve the same cleaning effect in a shorter time than the existing food cleaning device, thereby saving electric energy and water resources.

[0081] See also Figure 3 The housing 2 is provided with a UV lamp slot 4 with a front opening 41 , and the UV lamp is installed in the UV lamp slot 4 .

[0082] By setting up a UV lamp trough 4 and pre-setting an opening 41 with a fixed direction in the UV lamp trough 4, it is convenient for production personnel to quickly install the photocatalyst mechanism, avoiding the photocatalyst mechanism from being improperly installed or shifted during use, which leads to a decrease in the photocatalytic effect. In addition, the UV lamp trough 4 is arranged as a whole on the shell 2, which is convenient for production personnel to design the arrangement of components in the shell 2 in advance, so that the structure of the purification device 1 can be designed to be more compact.

[0083] The UV lamp slot 4 of the present embodiment extends from the side of the purification chamber 21 to the lower part of the purification chamber 21, the opening 41 is arranged at the lower part of the purification chamber 21, and the UV lamp is arranged at the lower part of the purification chamber 21 through the UV lamp slot 4. When the UV lamp is working, it irradiates ultraviolet light to the catalytic zone 37. Specifically, the UV lamp is arranged at the lower side of the vent 51 of the air diffusion channel 5 along the length direction of the air diffusion channel 5, and the interface kit 53 is provided with an opening 40 connected to the UV lamp slot 4.

[0084] Placing the UV lamp below the vent 51 has the following advantages:

[0085] (1) This arrangement can prevent the water flowing into the lower part of the shell 2 from being directly pushed by the air mass discharged from the vent 51 to flow toward the upper part of the shell 2, resulting in the water being irradiated by the UV lamp for too short a time and producing less disinfectant;

[0086] (2) Since the UV lamp can disinfect and sterilize the water body, and can catalyze and oxidize the pollutants in the water body, this arrangement can ensure that the water body flowing into the shell 2 is fully irradiated by the UV lamp before flowing to the upper part of the shell 2, thereby reducing the content of pollutants in the water body circulating between the outside world and the purification device 1.

[0087] See also Figure 3 and Fig.10 The mesh holes 13 are disposed at the upper and lower parts of the blocking cover 11 , and the middle part of the blocking cover 11 is inclined toward a side relative to the housing 2 to form a guide part 14 .

[0088] Since the guide portion 14 in the middle of the baffle 11 is in a closed state and tilted toward a side relative to the shell 2, it guides the water in the purification chamber 21, so that the water in the purification chamber 21 flows in a directional manner along the tilted direction of the guide portion 14, from the lower part of the purification chamber 21 to the upper part of the purification chamber 21, thereby realizing a water purification cycle. At the same time, since the guide portion 14 is tilted, the capacity of the purification device 1 is increased, so that the contact time between the water in the purification chamber 21 and the water catalyst mechanism 3 is longer, thereby improving the catalytic effect of the water catalyst mechanism 3; the connection between the upper part of the guide portion 14 and the baffle 11 is at a right angle, which can limit the flow direction of the water, thereby preventing the water from flowing to the upper part of the purification device 1.

[0089] See also Figure 3 and Fig.10The blocking cover 11 is connected to the front side of the shell 2 through a clamping structure, and the clamping structure includes a claw 61 and a slot 62; the claw 61 is arranged on the side of the blocking cover 11 facing the shell 2, and the slot 62 is arranged on the side of the shell 2 facing the blocking cover 11 corresponding to the claw 61; or, the claw 61 is arranged on the side of the shell 2 facing the blocking cover 11, and the slot 62 is arranged on the side of the blocking cover 11 facing the shell 2 corresponding to the claw 61.

[0090] In order to further improve the connection strength between the blocking cover 11 and the shell 2, the snap-on structure also includes an insert block 63 and a slot 64, the insert block 63 is arranged on the side of the blocking cover 11 facing the shell 2, and the slot 64 is arranged on the side of the shell 2 facing the blocking cover 11 corresponding to the insert block 63; or, the insert block 63 is arranged on the side of the shell 2 facing the blocking cover 11, and the slot 64 is arranged on the side of the blocking cover 11 facing the shell 2 corresponding to the insert block 63.

[0091] The blocking cover 11 is fixedly connected to the shell 2 through a snap-fit ​​structure, which can effectively improve the structural strength, prevent the purification device 1 from being damaged under the impact of water flow, and ensure that the blocking cover 11 protects the components in the purification chamber 21. In addition, the snap-fit ​​structure is simple in structure, which can reduce the difficulty of producing components and facilitate production personnel to assemble and disassemble the purification device 1.

[0092] See also Fig.10 After the blocking cover 11 is connected to the shell 2, a certain gap is left between the blocking cover 11 and the purification chamber 21. In order to prevent the first electrode terminal 31 and the second electrode terminal 32 from shaking, the blocking cover 11 is provided with a positioning block 16 corresponding to the first electrode terminal 31 and the second electrode terminal 32, and the positioning block 16 fixes the first electrode terminal 31 and the second electrode terminal 32.

[0093] See also Fig. 9 and Fig.10 A baffle 12 is provided on the baffle cover 11 corresponding to the top wall 28, and the mesh 13 on the upper part of the baffle cover 11 is located below the baffle 12; when the baffle cover 11 is assembled with the shell 2, the baffle 12 abuts against the upper end of the top wall 28; similarly, the top wall abutting against the upper end of the baffle is also a feasible solution for this implementation.

[0094] By respectively arranging a top wall 28 and a baffle 12 that can fit tightly together on the purification chamber 21 and the upper part of the blocking cover 11, when the purification device 1 is immersed in water, the upper part of the purification chamber 21 is relatively sealed, keeping the upper part of the purification chamber 21 dry, and preventing water from flowing into the upper part of the purification chamber 21 and contacting the first electrode terminal 31 and the second electrode terminal 32, causing leakage accidents, affecting the production and use of the purification device 1 and causing harm to the user; in addition, the step formed by the baffle 12 and the guide portion 14 can play a positioning role on the top wall 28, thereby facilitating the assembly of the blocking cover 11 and the shell 2.

[0095] Embodiment 2

[0096] See also Figure 11 to Figure 12 The difference between this embodiment and the first embodiment is that the purification device 1 further includes a water driving device 7, the water driving device 7 is connected to the purification chamber 21, and the water driving device 7 is used to drive the water in the purification chamber 21 to exchange with the external water.

[0097] The water catalyst mechanism 3 is disposed on one side of the purification chamber 21 , and a rear opening 20 is disposed on the other side of the purification chamber 21 . A water driving device 7 is disposed at the rear opening 20 of the purification chamber 21 .

[0098] The water driving device 7 and the air diffusion channel 5 jointly promote the exchange of water in the purification device 1 with water in the outside.

[0099] The water driving device 7 of this embodiment is a tubeless water pump, and the tubeless water pump is provided with a water inlet 71 and a water outlet 72 .

[0100] The working part of the tubeless water pump is placed in the purification device 1, avoiding external power devices and pipelines, reducing the loss of water pump power, thereby improving pumping efficiency, saving energy, and preventing purified water containing disinfectants from being contaminated by external water sources.

[0101] Compared with the prior art, a purification device 1 of the present invention has the following beneficial effects:

[0102] (1) The purification device 1 of the present invention is composed of three main components: a housing 2, a water catalyst mechanism 3, and a cover 11. The number of components is small, thereby reducing production costs and facilitating component production and assembly of the entire device. In addition, since pollutants may adhere to the surface of the water catalyst mechanism 3 after long-term use, reducing the purification effect of the purification device 1, the small number of components of the purification device 1 makes it easy for users to disassemble the purification device 1 and clean the water catalyst mechanism 3 separately, thereby ensuring the purification effect of the purification device 1 and extending the service life of the water catalyst mechanism 3.

[0103] (2) The purification device 1 of the present invention has a simple structure, which makes it easy for production personnel to make full use of the internal space of the purification device 1 and arrange the components in the purification device 1 more tightly, thereby effectively reducing the volume of the purification device 1. On the one hand, it can reduce the storage space required for transporting the purification device 1, effectively reducing the transportation cost. On the other hand, it can reduce the space required for installing the food purification equipment equipped with the purification device 1, reduce the space requirement for installing the food purification equipment, and facilitate users to install the food purification equipment.

[0104] (3) The water catalyst mechanism 3 of the present invention is connected to an external power source by penetrating the first electrode terminal 31 and the second electrode terminal 32 of the upper part of the shell 2. By extending the end of the water catalyst mechanism 3 connected to the external power source out of the upper part of the shell 2, it is avoided to open a hole in the middle or lower part of the side wall of the water tank 81. After the water in the water tank 81 soaks the purification device 1, the water will not seep out, thereby improving the sealing and safety performance of the purification device 1, and improving the aesthetics of the purification device 1.

[0105] Embodiment 3

[0106] See also Figure 13 to Figure 14 Another object of the present invention is to provide a food purification device 8 using the purification device 1 of the above-mentioned embodiment 1, which includes a water tank 81, a purification device 1 and a control device. The side wall of the water tank 81 is provided with a purification device installation groove 83, the front side of the purification device installation groove 83 is open and the rear side is closed, and the upper part of the rear side of the purification device installation groove 83 is provided with electrode holes corresponding to the first electrode terminal 31 and the second electrode terminal 32. The purification device 1 is installed in the purification device installation groove 83; the control device is used to control the working state of the purification device 1.

[0107] Specifically, the control device may be a controller (such as a control panel) disposed on the water tank 81, or the control device may be a mobile device (such as a mobile phone, a tablet, a smart wearable device, etc.).

[0108] See also Fig.15 A through hole 810 is provided on the side wall of the water tank 81, and the purification device installation groove 83 is arranged on the through hole 810. The peripheral wall of the purification device installation groove 83 is sealed and connected with the through hole 810 on the side of the water tank 81; this arrangement can ensure that the purification device installation groove 83 and the water tank 81 are in a sealed state, thereby preventing the water in the water tank 81 from leaking out from the purification device installation groove 83. When the purification device 1 is installed on the purification device installation groove 83, there is no need to add another sealing structure, thereby reducing the number of parts, simplifying the structure of the food purification device 1, and improving the safety of the food purification device 1.

[0109] See also Fig.18The peripheral wall of the purification device installation groove 83 is connected to the through hole 810. The purification device installation groove 83 includes a vertical wall 85, an upper plate 86, a lower plate 87 and two side plates 88. The two side plates 88 are respectively arranged on both sides of the vertical wall 85, the lower plate 87 is arranged on the lower side of the vertical wall 85, and the upper plate 86 is arranged on the upper side of the vertical wall 85, and is connected to the vertical wall 85, the side plate 88 and the inner wall of the through hole 810, so that the upper side of the purification device installation groove 83 is closed; the purification device installation groove 83 has a simple structure, and can be designed to be as small as possible while ensuring that sufficient space is reserved for the purification device 1 to be installed. On the one hand, it can make the internal structure of the food purification equipment 8 more compact On the other hand, it can reduce the space occupied by the food purification equipment 8 and facilitate the installation of the food purification equipment 8. On the other hand, it can reduce the area of ​​the purification device installation groove 83 immersed in the water body after the water tank 81 is filled with water, thereby reducing the space required for the user to clean the purification device installation groove 83 after disassembling the purification device 1 and shortening the cleaning time. In addition, the purification device installation groove 83 is a semi-closed structure composed of a vertical wall 85, an upper plate 86, a lower plate 87 and two side plates 88. By adjusting the relative positions of the upper plate 86, the lower plate 87 and the two side plates 88, the upper plate 86, the lower plate 87 and the two side plates 88 can play a positioning role for the purification device 1, which is convenient for the rapid installation of the purification device 1.

[0110] The lower plate 87 is inclined from the side of the vertical wall 85 to the side of the water tank 81; the lower plate 87 can guide the water body by adopting the above-mentioned setting method. When the water tank 81 is storing water, due to the inclination of the lower plate 87, the water capacity of the lower part of the purification device installation groove 83 is reduced, so that the water level in the water tank 81 rises faster, so that the water body can immerse the purification device 1 faster along the lower plate 87. In addition, when the water tank 81 is drained, the water body can flow to the middle part of the water tank 81 along the inclination direction of the lower plate 87, avoiding the water body that has cleaned the food from remaining in the purification device installation groove 83, reducing the cleanliness of the water tank 81, and affecting the purification effect of the food purification equipment 8 when cleaning the food next time.

[0111] A drain port 82 is provided on the side wall of the water tank 81 , and the drain port 82 is connected to an external drainage pipe. The height of the drain port 82 from the bottom of the water tank 81 is less than the height of the ends of the first electrode terminal 31 and the second electrode terminal 32 passing through the shell 2 from the bottom of the water tank 81 .

[0112] By setting the drain port 82, the water level in the water tank 81 is always lower than the upper part of the purification device installation tank 83, so as to avoid water soaking the upper part of the purification device installation tank 83. On the one hand, it can prevent pollutants in the water body that has been used to clean food from remaining in the upper part of the purification device installation tank 83, thereby reducing the cleanliness of the water tank 81 and affecting the purification effect of the food purification equipment 8 when cleaning food next time. On the other hand, it can prevent water from soaking the electrode terminals of the purification device 1 to cause leakage accidents, thereby ensuring the safety of the food purification equipment 8.

[0113] See also Fig. 9 , an extension portion 15 extending toward one side of the shell 2 is provided on the upper part of the blocking cover 11; when the purifier 1 is assembled into the purifier mounting groove 83, the extension portion 15 is tightly matched with the inner wall of the purifier mounting groove 83; this arrangement can prevent water droplets from entering the upper part of the purifier 1 from the connection between the blocking cover 11 and the water groove 81 when the water in the water tank 81 splashes onto the side wall of the water tank 81 during the flow, thereby improving the waterproof performance of the upper part of the purifier 1. In addition, the blocking cover 11 adopts the above-mentioned structure, so there is no need to set an upper cover on the purifier 1, which can reduce the production cost of the purifier 1, and there is no need to consider the matching degree between the upper end of the purifier 1 and the purifier mounting groove 83, thereby reducing the requirements for the installation accuracy of the purifier 1.

[0114] It also includes a water inlet mechanism (not shown in the figure), which includes a water supply device and a water level monitor. The water inlet of the water supply device is connected to the water supply pipe, and the water outlet of the water supply device is arranged in the purification device installation groove 83; the water level monitor is arranged in the water tank 81 to monitor the water level in the water tank 81.

[0115] The water supply device is a water supply pump.

[0116] Specifically, in order to simplify the structure of the water tank 81, the water level monitor is arranged in the purification device installation groove 83. A water inlet hole 90 is arranged in the purification device installation groove 83 corresponding to the water outlet of the water supply device, and a water level monitor installation hole 91 is arranged corresponding to the water level monitor; the water inlet hole 90 is located above the plane where the water drain port 82 is located, and the water level monitor installation hole 91 is located below the plane where the water drain port 82 is located, and the water inlet hole 90 and the water level monitor installation hole 91 are arranged corresponding to the air avoidance hole 29 of the purification device 1.

[0117] By providing the water inlet mechanism, it is convenient for the user to realize automatic water inflow into the water tank 81 by controlling the opening and closing of the water supply device, thereby improving the degree of automation of the water tank 81 and improving the user experience. Moreover, it is only necessary to provide an opening matching the water supply device on the purification device installation groove 83, and there is no need to open another hole on the water tank 81, thereby reducing the difficulty of processing the water tank. In addition, by providing the water outlet of the water supply device in the purification device installation groove 83, on the one hand, the thrust generated when the water supply device outputs the water body can be used to promote the circulation of the water body in the purification device 1, thereby increasing the flow speed and external diffusion speed of the water body in the purification device 1 while reducing energy consumption. On the other hand, the water body input into the water tank 81 flows into the water tank 81 after being purified by the purification device 1. Compared with the water body input into the water tank 81 flowing for a distance before entering the purification device 1, it can improve the purification efficiency and shorten the time required for purifying food.

[0118] The purpose of adding a water inlet mechanism in the present embodiment is to realize automatic water inlet into the water tank 81, which is a preferred scheme of the present embodiment. In order to reduce production costs, the setting of the water inlet mechanism can also be omitted, and the water tank 81 can be directly filled with water using a faucet. Therefore, the food purification equipment 8 without a water inlet mechanism also falls within the protection scope of the present invention.

[0119] Embodiment 4

[0120] See also Figure 11 to Figure 12 , Fig.19 This embodiment is an improved solution of the third embodiment. The food purification device of this embodiment is also provided with a water driving device 7.

[0121] The water catalyst mechanism 3 is arranged on one side of the purification chamber 21, and a rear opening 20 is provided on the other side of the purification chamber 21. A water body driving device 7 is provided at the rear side of the purification device installation groove 83 corresponding to the rear opening 20 of the purification chamber 21; when the purification device 1 is installed in the purification device installation groove 83, the water body driving device 7 is located in the purification chamber 21.

[0122] By providing a water driving device 7, the water in the purification device 1 can be exchanged with the external water, thereby increasing the water circulation speed and improving the purification efficiency of the food purification equipment 8. In addition, the water driving device can contact the external water through the baffle 11 with a mesh 13. When the purification device 1 is placed in the water tank 81, the water driving device 7 can drive the water in the water tank 81 to flow quickly, thereby improving the cleaning effect of the food purification equipment 8 on the food.

[0123] In the related drawings of the fourth embodiment, in order to facilitate the understanding of the scheme, the water driving device 7 is shown to be placed in the purification chamber 21.

[0124] Compared with the prior art, the food purification device 8 of the present invention has the following beneficial effects:

[0125] (1) The food purification device 8 of the present invention generates hydroxyl radicals by decomposing water. Hydroxyl radicals have a strong ability to obtain electrons and can react with organic matter (such as pesticide residues and hormones) to oxidize the organic matter into substances that are harmless to the human body, such as oxygen, carbon dioxide, water, mineral salts, etc. Therefore, the present invention has high safety and a stable and reliable cleaning effect, and can fully meet the cleaning and disinfection needs of fruit and vegetable products and utensils in daily life;

[0126] (2) The food purification device 8 of the present invention is composed of a water tank 81 and a purification device 1. By providing a purification device installation slot 83 in the water tank 81 for installing the purification device 1, it is convenient for users to install the purification device 1 and disassemble it for cleaning, thereby reducing the maintenance cost of the food purification device 8;

[0127] (3) The purification device 1 of the present invention is installed in the purification device installation groove 83, so there is no need to set other sealing structures on the side wall of the water tank 81 to seal with the purification device 1. On the one hand, it can effectively reduce the difficulty of processing the water tank 81 and reduce production costs. On the other hand, it can effectively improve the sealing performance of the food purification equipment 8, prevent the water in the water tank 81 from flowing out from the connection between the water tank 81 and the purification device 1, and improve the safety of the food purification equipment 8.
