Description

Technical Field

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

[0002] Pesticides, hormones, dust, germs and other pollutants may remain on the surface of fruit and vegetable products. Eating unclean fruit and vegetable products may 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. A water outlet is provided on the inner wall of the sink, and the purification device is arranged on the outside of the sink. The purification device and the water outlet are sealed and connected by a sealing ring. The purification device of this type of food cleaning device is located on the outside of the sink, which is difficult to assemble and inconvenient to disassemble and clean. At the same time, in order to facilitate the installation of the purification device, the water outlet needs to be processed accordingly, which increases the difficulty of processing the sink and the production cost. In addition, the purification device and the water outlet are sealed with a sealing ring, which has strict requirements on the selection of the sealing ring. The sealing ring will age after long-term use, and the leak-proof effect will decrease, which may easily cause 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 deficiencies of the prior art and provide a food purification device, which facilitates the installation and removal of the purification device by arranging a purification device installation groove in the water tank and improves the sealing performance of the water tank.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a food purification equipment, including a water tank, a purification device and a control device; 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 rear side is closed, and the purification device is installed in the purification device installation groove through the front side opening; the control device is used to control the working state of the purification device; the purification device includes a shell and a water catalyst mechanism, the water catalyst mechanism is installed in the shell, and the front side of the purification device is provided with a water passage connecting the water catalyst mechanism and the inside of the water tank, the water catalyst mechanism includes an electrode unit and an electrode terminal, and the end of the electrode terminal extends out of the upper part of the shell; the upper part of the side wall of the purification device installation groove is provided with an electrode assembly hole, and the electrode terminal is connected to an external power supply through the electrode assembly hole.

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

[0006] (1) A food purification device of the present invention has a purification device installation groove provided in a water tank, so that the purification device can be quickly installed in the purification device installation groove, thereby eliminating the need to provide other sealing structures on the side wall of the water tank to seal with the purification device. On the one hand, the processing difficulty of the water tank can be effectively reduced, and the production cost can be reduced. On the other hand, the sealing performance of the food purification device can be effectively improved, and the water in the water tank can be prevented from flowing out from the connection between the water tank and the purification device, thereby improving the safety of the food purification device.

[0007] (2) The purification device installation tank of the present invention can be installed as a separate product on any water tank body provided with a through hole that matches it, thereby overcoming the problem that the purification device cannot be applied to water tanks of different specifications, increasing the applicable scope of the purification device, and reducing the installation and maintenance costs, which is convenient for the promotion and use of the purification device; and when the user needs to replace a water tank of other specifications, the purification device and the purification device installation tank of the original water tank can be disassembled, and the purification device installation tank can be fixed to the new water tank for installation of the purification device, thereby reducing the replacement cost of the new food purification equipment, realizing the recycling of the purification device and the purification device installation tank, and reducing the waste of resources;

[0008] (3) The water catalyst mechanism of the purification device is connected to the external power source through the electrode terminal passing through 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, the electrode assembly hole that connects the purification device installation tank with the outside is set at the upper part of the purification device installation tank, and the electrode assembly hole is as far away from the bottom of the water tank as possible, thereby improving the sealing and safety performance of the purification device, and preventing the water in the water tank from seeping out from the electrode assembly hole as the water level in the water tank rises, causing the water containing pollutants in the water tank to flow out of the water tank, and the outflowing water to affect external equipment.

[0009] Preferably, the shell is provided with a purification chamber, the purification chamber is provided with a front opening, and the front opening forms the water passage; the water catalyst mechanism is installed in the purification chamber, the electrode unit is composed of a plurality of first pole pieces and second pole pieces arranged alternately, the electrode terminals include a first electrode terminal and a second electrode terminal, the first electrode terminal and the second electrode terminal are arranged at the upper part of the electrode unit, each first pole piece is connected to the first electrode terminal, and each second pole piece is connected to the second electrode terminal, and a catalytic zone is formed between adjacent first pole pieces and second pole pieces; a detachable baffle cover is provided on the front side of the shell, and a mesh hole connected to the front opening of the purification chamber is provided on the baffle cover.

[0010] The above purification device has the following beneficial effects:

[0011] (1) The purification device is composed of three main parts: a shell, a water catalyst mechanism and a cover. The number of parts is small, thereby reducing production costs and facilitating the production of parts and assembly of the whole device. In addition, after long-term use, pollutants will adhere to the surface of the water catalyst mechanism, reducing the purification effect of the purification device. The small number of parts 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.

[0012] (2) The purification device 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.

[0013] 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.

[0014] 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, so that production personnel can design the purification device to be smaller. In addition, this arrangement can facilitate installation by production personnel, increase the speed of assembling the water catalyst mechanism, thereby improving production efficiency, and only need to connect the first electrode terminal and the second electrode terminal to the external power supply to start a plurality of first pole pieces and a plurality of second pole pieces at the same time, thereby reducing the connection ports between the purification device and the external power supply, thereby avoiding the need to set a plurality of through holes for the power supply terminals to pass through on the purification device installation groove, and effectively improving the sealing of the purification device installation groove.

[0015] Preferably, the position of the electrode assembly hole is higher than the position of the water tank drain port.

[0016] This arrangement ensures that the water level in the water tank is always lower than the through-holes for installing the electrode terminals on the purification device, thereby preventing water from soaking the electrode terminals of the purification device. On the one hand, it solves the problem of water leakage caused by poor sealing. On the other hand, it prevents water from soaking through the electrode assembly holes and contacting the electrode terminals of the purification device, causing leakage accidents, thereby ensuring the safety of food purification equipment.

[0017] Preferably, the electrode terminal extends out of the rear side of the upper portion of the shell, and the electrode assembly hole is arranged on the upper portion of the rear wall of the purification device installation slot.

[0018] Since there is enough space on the rear side of the upper part of the shell, this arrangement can facilitate the arrangement of the electrode terminals, thereby reducing the difficulty of designing and producing the purification device, thereby reducing the production cost.

[0019] Preferably, the lower side surface of the purification device installation tank is inclined from the rear side to one side of the water tank.

[0020] The above-mentioned arrangement of the lower side of the purification device installation groove can guide the water body. When the sink is storing water, due to the inclination of the lower side of the purification device installation groove, the water capacity of the lower part of the purification device installation groove is reduced, so that the water level in the sink rises faster, and the water body can immerse the purification device faster along the lower side of the purification device installation groove. In addition, when the sink is draining, the water body can flow to the middle of the sink along the inclination direction of the lower side of the purification device installation groove, thereby avoiding the water body that has been used to clean food from remaining in the purification device installation groove, reducing the cleanliness of the sink, and affecting the purification effect of the food purification equipment when cleaning food next time.

[0021] Preferably, it also includes a connecting assembly for connecting the electrode terminal to the water tank; the shell is provided with a through hole for the electrode terminal to pass through; the connecting assembly includes a fixing kit and a fixing part, the fixing kit is arranged on the rear side of the through hole, and the electrode terminal can pass through the corresponding through hole and the fixing kit in sequence; the fixing kit passes through the electrode assembly hole, and the fixing part connects the fixing kit and the water tank wall.

[0022] 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.

[0023] Preferably, the purification chamber is provided with a top wall above the electrode unit; a baffle is provided on the baffle cover corresponding to the top wall, and the mesh of the baffle cover is located below the baffle plate; when the baffle cover is assembled with the shell, the baffle plate abuts against the upper end of the top wall; or, the top wall abuts against the upper end of the baffle plate.

[0024] By respectively arranging a top wall and a baffle plate that can fit tightly in the purification chamber and the upper part of the baffle cover, when the purification device is immersed in water, the upper part of the purification chamber is in a relatively sealed state, keeping the upper part of the purification chamber dry, and preventing water from flowing into the upper part of the purification chamber and contacting the two electrode terminals, causing leakage accidents, affecting the normal use of the purification device and causing harm to the user; in addition, the step formed by the baffle plate and the middle part of the baffle cover can position the top wall, thereby facilitating the assembly of the baffle cover and the shell.

[0025] 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.

[0026] 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 a mesh. 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 food purification equipment on the food.

[0027] Preferably, it further comprises a water inlet mechanism, wherein the water inlet mechanism comprises a water supply device, the water inlet of the water supply device is connected to an external water supply pipeline, and the water outlet of the water supply device is arranged in the installation groove of the purification device.

[0028] By providing the water inlet mechanism, it is convenient for the user to realize automatic water inflow into the sink by controlling the opening and closing of the water supply device, thereby improving the automation degree of the sink and improving the user experience. Moreover, it is only necessary to provide an opening matching the water supply device on the purification device installation slot, and there is no need to open another hole on the sink, thereby reducing the difficulty of processing the sink. In addition, by providing the water outlet of the water supply device in the purification device installation slot, on the one hand, the thrust generated when the water supply device outputs water can be used to promote the circulation of the water in the purification device, thereby increasing the flow rate and external diffusion rate of the water in the purification device while reducing energy consumption. On the other hand, the water input into the sink flows into the sink only after being purified by the purification device. Compared with the water input into the sink flowing a certain distance before entering the purification device, the purification efficiency can be improved and the time required for purifying food can be shortened.

DETAILED DESCRIPTION

[0051] The following describes the embodiments of the present invention in conjunction with the accompanying drawings:

[0052] Embodiment 1

[0053] See also Figures 1 to 5 , Figure 8 and Fig. 9 , A food purification device of the present embodiment includes a water tank 1, a purification device 2 and a control device; a purification device installation groove 8 is provided on the side wall of the water tank 1, the purification device installation groove 8 is open at the front side and closed at the rear side, and the purification device 2 is installed in the purification device installation groove 8 through the front side opening; the control device is used to control the working state of the purification device 2; the purification device 2 includes a shell 26 and a water catalyst mechanism 3, the water catalyst mechanism 3 is installed in the shell 26, and a water passage connecting the water catalyst mechanism 3 and the inside of the water tank 1 is provided on the front side of the purification device 2, the water catalyst mechanism 3 includes an electrode unit and an electrode terminal, and the end of the electrode terminal extends out of the upper part of the shell 26; an electrode assembly hole 87 is provided on the upper part of the side wall of the purification device installation groove 8, and the electrode terminal is connected to an external power supply through the electrode assembly hole 87.

[0054] Specifically, the control device can be a controller (such as a control panel) arranged on the sink 1, or the control device can be a mobile device (such as a mobile phone, a tablet, a smart wearable device, etc.), and the control device can control the startup, shutdown, working time and working power of the purification device 2.

[0055] Specifically, a through hole 11 is provided on the side wall of the water tank 1 , and the purification device installation groove 8 is arranged on the through hole 11 .

[0056] In order to ensure that the cleaning range radiated by the purification device 2 is as large as possible, the purification device installation groove 8 is arranged in the middle of the side wall of the water tank 1, so that the water purified by the purification device 2 can be radiated to the entire water tank 1.

[0057] See also Figures 1 to 5 The electrode terminal extends out of the upper rear side of the shell 26, and the electrode assembly hole 87 is provided on the upper rear wall of the purification device installation slot 8.

[0058] Since there is enough space on the upper rear side of the shell 26, this arrangement can facilitate the arrangement of the electrode terminals, thereby reducing the difficulty of designing and producing the purification device 2, thereby reducing the production cost.

[0059] See also Figure 6 to Figure 7 This embodiment provides the following two ways of setting the purification device installation slot 82:

[0060] The first arrangement of the purification device installation groove 82: the peripheral wall of the purification device installation groove 8 is connected to the through hole 11, and the purification device installation groove 8 includes a vertical wall 83, a lower plate 84 and two side plates 85, the two side plates 85 are respectively arranged on both sides of the vertical wall 83, and the lower plate 84 is arranged on the lower side of the vertical wall 83.

[0061] The above configuration has the following beneficial effects:

[0062] (1) The peripheral wall of the purification device installation groove 8 is connected to the through hole 11, which can ensure that the purification device installation groove 8 and the water tank 1 are in a sealed state, thereby preventing the water in the water tank 1 from leaking out from the purification device installation groove 8. When the purification device 2 is installed in the purification device installation groove 8, there is no need to add another waterproof sealing structure, thereby reducing the number of parts, simplifying the structure of the food purification device 2, and improving the safety of the food purification device 2;

[0063] (2) The purification device installation groove 8 has a simple structure and can be designed to be smaller in size while ensuring that sufficient space is reserved for the installation of the purification device 2. On the one hand, it can make the internal structure of the food purification equipment more compact, thereby reducing the space occupied by the food purification equipment and facilitating the installation of the food purification equipment. On the other hand, it can reduce the area of ​​the purification device installation groove 8 immersed in the water body after the water tank 1 is filled with water, thereby reducing the space required for the user to clean the purification device installation groove 8 after disassembling the purification device 2, thereby shortening the cleaning time.

[0064] The second arrangement method of the purification device installation groove 82: the purification device installation groove 8 includes an upper plate 86, a vertical wall 83, a lower plate 84 and two side plates 85, the two side plates 85 are respectively arranged on both sides of the vertical wall 83, the lower plate 84 is arranged on the lower side of the vertical wall 83, and the upper plate 86 is arranged on the upper side of the vertical wall 83, and is connected to the vertical wall 83, the side plate 85 and the inner wall of the through hole 11, so that the upper side of the purification device installation groove 8 is closed.

[0065] By providing the upper plate 86, the sealing between the purification device installation groove 8 and the water tank 1 is improved, and the water level in the water tank 1 is prevented from being higher than the upper end of the purification device installation groove 8, which causes water to seep out from the upper end of the purification device installation groove 8, thereby further improving the safety of the food purification equipment. In addition, the purification device installation groove 8 is a semi-closed structure composed of a vertical wall 83, an upper plate 86, a lower plate 84 and two side plates 85. By adjusting the relative positions of the upper plate 86, the lower plate 84 and the two side plates 85, the upper plate 86, the lower plate 84 and the two side plates 85 can play a positioning role for the purification device 2, thereby facilitating the rapid installation of the purification device 2.

[0066] If the purification device installation groove 82 adopts the above-mentioned first setting method, the upper end of the purification device installation groove 82 is open, and the power supply line of the purification device 2 can pass through the upper end of the purification device installation groove 82. If the purification device installation groove 82 adopts the above-mentioned second setting method, the power supply line of the purification device 2 can pass through the upper plate 86 of the purification device installation groove 82 or the upper part of the vertical wall 83 or the upper part of the side plate 85; although the drawings of the present embodiment only show the drawings of the purification device installation groove 82 adopting the above-mentioned second setting method, the first setting method of the purification device installation groove 82 also belongs to the protection scope of the claims of the present invention.

[0067] The lower side surface of the purification device installation groove 8 is inclined from the rear side to the side of the water tank 1.

[0068] The above-mentioned arrangement of the lower side of the purification device installation groove 8 can guide the water body. When the water tank 1 is storing water, due to the inclination of the lower side of the purification device installation groove 8, the water capacity of the lower part of the purification device installation groove 8 is reduced, so that the water level in the water tank 1 rises faster, so that the water body can immerse the purification device 2 faster along the lower side of the purification device installation groove 8. In addition, when the water tank 1 is drained, the water body can flow to the middle part of the water tank 1 along the inclination direction of the lower side of the purification device installation groove 8, thereby avoiding the water body that has been used to clean food from remaining in the purification device installation groove 8, reducing the cleanliness of the water tank 1, and affecting the purification effect of the food purification equipment when cleaning food next time.

[0069] See also Figures 8 to 14 The shell 26 is provided with a purification chamber 261, and the purification chamber 261 is provided with a front opening, and the front opening forms the water passage; the water catalyst mechanism 3 is installed in the purification chamber 261, and the electrode unit is composed of a plurality of first pole pieces 4 and second pole pieces 5 arranged alternately, and the electrode terminals include first electrode terminals 31 and second electrode terminals 32, and the first electrode terminals 31 and the second electrode terminals 32 are arranged at the upper part of the electrode unit, each first pole piece 4 is connected to the first electrode terminal 31, and each second pole piece 5 is connected to the second electrode terminal 32, and a catalytic zone 6 is formed between adjacent first pole pieces 4 and second pole pieces 5; a detachable blocking cover 21 is provided on the front side of the shell 26, and a mesh 23 connected to the front opening of the purification chamber 261 is provided on the blocking cover 21.

[0070] The above purification device 2 has the following beneficial effects:

[0071] (1) The purification device 2 is composed of three main components: a housing 26, a water catalyst mechanism 3, and a cover 21. 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 3 after long-term use, reducing the purification effect of the purification device 2, the small number of components of the purification device 2 makes it easy for users to disassemble the purification device 2 and clean the water catalyst mechanism 3 separately, thereby ensuring the purification effect of the purification device 2 and extending the service life of the water catalyst mechanism 3.

[0072] (2) The purification device 2 has a simple structure, which makes it easy for production personnel to make full use of the internal space of the purification device 2 and arrange the components in the purification device 2 more tightly, thereby effectively reducing the volume of the purification device 2. On the one hand, it can reduce the storage space required for transporting the purification device 2, effectively reducing the transportation cost. On the other hand, it can reduce the space required for installing the food purification equipment, reduce the space requirement for installing the food purification equipment, and facilitate users to install the food purification equipment.

[0073] See also Fig.15, the first pole piece 4 and the second pole piece 5 are arranged vertically; the upper end of each first pole piece 4 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 5 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.

[0074] The above-mentioned arrangement integrates a plurality of first pole pieces 4, the lower end of the first electrode terminal 31 and the first power board 33, and a plurality of second pole pieces 5, 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, so that the production personnel can design the purification device 2 to be smaller. In addition, this arrangement can facilitate the installation of the production personnel, increase the speed of assembling the water catalyst mechanism 3, thereby improving the production efficiency, and only need to connect the first electrode terminal 31 and the second electrode terminal 32 to the external power supply, so as to start a plurality of first pole pieces 4 and a plurality of second pole pieces 5 at the same time, thereby reducing the connection port of the purification device 2 with the external power supply, thereby avoiding the provision of a plurality of through holes for the power supply terminals to pass through on the purification device installation groove 8, and effectively improving the sealing of the purification device installation groove 8.

[0075] See also Fig.15 A first rear step 42 is provided on the rear side of the upper end of the first pole piece 4, and the first power connection plate 33 is installed on the front side of the upper end of the first pole piece 4; a second front step 52 is provided on the front side of the upper end of the second pole piece 5, and the second power connection plate 34 is installed on the rear side of the upper end of the second pole piece 5; when the first pole piece 4 and the second pole piece 5 are combined, the first power connection plate 33 is located on the upper side of the second front step 52, and the second power connection plate 34 is located on the upper side of the first rear step 42.

[0077] The above-mentioned arrangement of the first pole piece 4 and the second pole piece 5 has the following beneficial effects: through the first rear step 42 of the first pole piece 4, the second front step 52 on the second pole piece 5 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 2 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.

[0078] 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 4 and the second electrode piece 5 are the cathode plate and the anode plate respectively, and the electron charge is transferred between the adjacent first electrode piece 4 (cathode plate) and the second electrode piece 5 (anode plate), and the water body will undergo a decomposition reaction (H=H + +H - ), quickly generate hydroxyl radicals; in this embodiment, the first electrode terminal 31 and the second electrode terminal 32 are bent.

[0079] See also Fig.16 The bottom wall of the purification chamber 261 is provided with a plurality of lower positioning grooves 264 corresponding to the first electrode piece 4 and the second electrode piece 5, and the top wall 269 of the purification chamber 261 is provided with upper positioning grooves 265 corresponding to the first electrode terminal 31 and the second electrode terminal 32. The lower ends of the first electrode piece 4 and the second electrode piece 5 are clamped in the corresponding lower positioning grooves 264, and the first electrode terminal 31 and the second electrode terminal 32 are arranged in the corresponding upper positioning grooves 265.

[0080] By providing the lower positioning groove 264 and the upper positioning groove 265, 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 261, 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 the food purification equipment) of the purification device 2, thereby reducing the purification effect of the purification device 2, and to avoid displacement and contact between adjacent electrode plates under the impact of the water flow, thereby preventing the purification device 2 from being used normally.

[0081] See also Figures 8 to 11 , Fig.16 , and also includes a connecting component for connecting the electrode terminal to the water tank 1; the shell 26 is provided with a through hole 266 for the electrode terminal to pass through; the connecting component includes a fixing kit 268 and a fixing member (not shown in the figure), the fixing kit 268 is arranged at the rear side of the through hole 266, and the electrode terminal can pass through the corresponding through hole 266 and the fixing kit 268 in turn; the fixing kit 268 passes through the electrode assembly hole 87, and the fixing member connects the fixing kit 268 and the wall of the water tank 1.

[0082] Specifically, the fixing kit 268 is threadedly connected to the fixing piece. The fixing piece in this embodiment is a nut. The fixing kit 268 is integrally arranged with the shell 26. In order to avoid the tightness and waterproof performance between the electrode terminal and the via hole 266, a sealing ring 267 is provided in the via hole 266.

[0083] The connecting assembly has a simple structure, which can effectively reduce the difficulty of installing and disassembling the purification device 2, and is convenient for production personnel and users to install the purification device 2, and to disassemble the purification device 2 for cleaning. The connecting assembly is stable and reliable, so that the purification device 2 can be firmly fixed on the side wall of the water tank 1 to prevent the purification device 2 from shaking during operation. In addition, the connecting assembly is arranged at the position corresponding to the shell 26 and the first electrode terminal 31 and the second electrode terminal 32. On the one hand, when producing the shell 26, a through hole 266 and a fixing kit 268 for the first electrode terminal 31 and the second electrode terminal 32 to pass through can be arranged at the same time, thereby reducing the processing steps and shortening the production time, and avoiding the setting of a fixing structure at other positions of the shell 26, so that the volume of the purification device 2 can be designed to be smaller. On the other hand, since the connecting assembly is arranged on the upper part of the shell 26, it can prevent the water in the water tank 1 from seeping out from the surrounding side of the connecting assembly, and the fixing kit 268 can fix the first electrode terminal 31 and the second electrode terminal 32 and improve the structural strength.

[0084] In order to reduce the production cost and weight of the purification device 2 and ensure that the connection assembly can firmly fix the purification device 2 , a clearance hole 27 is provided on the housing 26 .

[0085] See also Fig.11 The shell 26 is provided with a gas diffusion channel 64, and the gas diffusion channel 64 is provided with a vent 65 for ventilating the catalytic zone 6. The upper part of the shell 26 is provided with a gas supply interface 66 connected to the gas diffusion channel 64 for connecting to a gas supply source.

[0086] When the purification device 2 is working, the gas supply source supplies gas from the gas supply interface 66 to the gas diffusion channel 64, and the gas is ejected from the vent 65. The ejected gas and water form a surge and flow toward the upper part of the shell 26, thereby promoting the flow of water in the purification chamber 261.

[0087] Specifically, the air diffusion channel 64 extends from the side of the purification chamber 261 to the lower part of the purification chamber 261 , and the vent 65 is disposed at the lower part of the purification chamber 261 .

[0088] The above arrangement of using the gas discharged from the gas diffusion channel 64 to drive the water flow in the purification chamber 261 has the following advantages:

[0089] (1) By controlling the airflow direction and airflow speed of the gas discharged from the diffuser channel 64, a mechanical boosting effect is generated on the circulation of the water body in the purification chamber 261, thereby promoting the rapid circulation exchange between the purified water containing disinfectants in the purification chamber 261 and the external water body, and preventing the water body from flowing back, ensuring the directional flow of the water body, and improving the working efficiency of the purification device 2;

[0090] (2) The gas diffusion channel 64 is placed as a whole in the purification chamber 261, which can make the internal structure of the purification device 2 more compact, thereby reducing the space occupied by the purification device 2 and facilitating the installation of the purification device 2;

[0091] (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 2.

[0092] See also Figures 4 to 9 Specifically, an interface kit 67 and a fixing part (not shown in the figure) are provided on the outside of the air supply interface 66. The interface kit 67 is fixedly arranged on the outside of the end of the air supply interface 66 that passes through the shell 26. The inner wall of the sink 1 is provided with an air supply through hole 89 corresponding to the interface kit 67. The interface kit 67 is inserted into the air supply through hole 89. The fixing part is connected to the end of the interface kit 67 inserted into the air supply through hole 89, so that the interface kit 67 is fixedly connected to the inner wall of the sink 1. The interface kit 67 can fix the air supply interface 66 and improve the structural strength.

[0093] In order to ensure the best driving effect of the air diffusion channel 64 on the water body, the vent 65 of the air diffusion channel 64 is set at the lower part of the purification chamber 261, and the vent 65 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 64 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 2, 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 2, on the one hand, prolonging the contact time between the water body and the second pole piece 5 and the first pole piece 4, 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 2, 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.

[0094] See also Figures 8 to 11 A photocatalyst mechanism (not shown in the figure) is provided on one side of the shell 26. The photocatalyst mechanism includes a UV lamp. When the photocatalyst mechanism is powered on, it performs photocatalysis on the water in the catalytic zone 6.

[0095] The purification device 2 of the present invention is provided with a photocatalyst mechanism, which has the following beneficial effects: the water body will have energy band bending after being irradiated by light, and the water body will undergo a decomposition reaction (H=H + +H -), 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 2, thereby improving the efficiency of the purification device 2 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 2 of the present invention can achieve the same cleaning effect in a shorter time than the existing food cleaning device, thereby saving electrical energy and water resources.

[0096] See also Figures 8 to 9 The housing 26 is provided with a UV lamp slot 61 with a front opening 62 , and the UV lamp is installed in the UV lamp slot 61 .

[0097] By setting up a UV lamp trough 61 and pre-setting an opening 62 with a fixed direction in the UV lamp trough 61, it is convenient for production personnel to quickly install the photocatalyst mechanism, thereby avoiding the photocatalyst mechanism being improperly installed or shifted during use, which may lead to a decrease in the photocatalytic effect. In addition, the UV lamp trough 61 is arranged as a whole on the shell 26, which is convenient for production personnel to design the arrangement of components in the shell 26 in advance, so that the structure of the purification device 2 can be designed to be more compact.

[0098] The UV lamp trough 61 of the present embodiment extends from the side of the purification chamber 261 to the lower part of the purification chamber 261, the opening 62 is arranged at the lower part of the purification chamber 261, and the UV lamp is arranged at the lower part of the purification chamber 261 through the UV lamp trough 61. When the UV lamp is working, it irradiates ultraviolet light to the catalytic zone 6. Specifically, the UV lamp is arranged at the lower side of the vent 65 of the air diffusion channel 64 along the length direction of the air diffusion channel 64, and the interface kit 67 is provided with an opening 60 connected to the UV lamp trough 61.

[0099] Placing the UV lamp below the vent 65 has the following advantages:

[0100] (1) This arrangement can prevent the water flowing into the lower part of the shell 26 from being directly pushed by the air mass discharged from the vent 65 to flow toward the upper part of the shell 26, resulting in the water being irradiated by the UV lamp for too short a time and producing less disinfectant;

[0101] (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 26 is fully irradiated by the UV lamp before flowing to the upper part of the shell 26, thereby reducing the content of pollutants in the water body circulating between the outside world and the purification device 2.

[0102] See also Fig.15 The mesh holes 23 are disposed on the upper and lower parts of the blocking cover 21 , and the middle part of the blocking cover 21 is inclined toward a side relative to the shell 26 .

[0103] The middle part of the blocking cover 21 is inclined toward the side relative to the shell 26 to form a guide portion 24. Since the guide portion 24 in the middle part of the blocking cover 21 is in a closed state and inclined toward the side relative to the shell 26, it guides the water in the purification chamber 261, so that the water in the purification chamber 261 flows in a directional manner along the inclined direction of the guide portion 24, and flows from the lower part of the purification chamber 261 to the upper part of the purification chamber 261, thereby realizing a water purification cycle. At the same time, since the guide portion 24 is inclined, the capacity of the purification device 2 is increased, and the contact time between the water in the purification chamber 261 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 24 and the blocking cover 21 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 2.

[0104] See also Figure 8 , Fig.14 and Fig.15 The blocking cover 21 is connected to the front side of the shell 26 through a clamping structure, and the clamping structure includes a claw 671 and a slot 672; the claw 671 is arranged on the side of the blocking cover 21 facing the shell 26, and the slot 672 is arranged on the side of the shell 26 facing the blocking cover 21 corresponding to the claw 671; or, the claw 671 is arranged on the side of the shell 26 facing the blocking cover 21, and the slot 672 is arranged on the side of the blocking cover 21 facing the shell 26 corresponding to the claw 671.

[0105] In order to further improve the connection strength between the blocking cover 21 and the shell 26, the snap-on structure also includes an insert block 673 and a slot 674, the insert block 673 is arranged on the side of the blocking cover 21 facing the shell 26, and the slot 674 is arranged on the side of the shell 26 facing the blocking cover 21 corresponding to the insert block 673; or, the insert block 673 is arranged on the side of the shell 26 facing the blocking cover 21, and the slot 674 is arranged on the side of the blocking cover 21 facing the shell 26 corresponding to the insert block 673.

[0106] The blocking cover 21 is fixedly connected to the shell 26 via a snap-fit ​​structure, which can effectively improve the structural strength, prevent the purification device 2 from being damaged by the impact of water flow, and ensure that the blocking cover 21 protects the components in the purification chamber 261. 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 2.

[0107] See also Fig.15After the blocking cover 21 is connected to the shell 26, a certain gap is left between the blocking cover 21 and the purification chamber 261. In order to prevent the first electrode terminal 31 and the second electrode terminal 32 from shaking, the blocking cover 21 is provided with a positioning block 28 corresponding to the first electrode terminal 31 and the second electrode terminal 32. The positioning block 28 fixes the first electrode terminal 31 and the second electrode terminal 32.

[0108] The purification chamber 261 is located above the electrode unit and is provided with a top wall 269; a baffle 22 is provided on the blocking cover 21 corresponding to the top wall 269, and the mesh 23 of the blocking cover 21 is located below the baffle 22; when the blocking cover 21 is assembled with the shell 26, the baffle 22 abuts against the upper end of the top wall 269; or, the top wall 269 abuts against the upper end of the baffle 22.

[0109] By respectively arranging a top wall 269 and a baffle 22 that can fit tightly together on the purification chamber 261 and the upper part of the blocking cover 21, when the purification device 2 is immersed in water, the upper part of the purification chamber 261 is relatively in a sealed state, keeping the upper part of the purification chamber 261 dry, and preventing water from flowing into the upper part of the purification chamber 261 and contacting the two electrode terminals, causing leakage accidents, affecting the normal use of the purification device 2 and causing harm to the user; in addition, the step formed by the baffle 22 and the middle part of the blocking cover 21 can position the top wall 269, thereby facilitating the assembly of the blocking cover 21 and the shell 26.

[0110] An extension portion 25 extending toward one side of the housing 26 is disposed on the upper portion of the blocking cover 21 ; when the purification device 2 is assembled into the purification device installation slot 8 , the extension portion 25 is tightly matched with the inner wall of the purification device installation slot 8 .

[0111] This arrangement can prevent water in the water tank 1 from splashing onto the side wall of the water tank 1 during the flow, and prevent water droplets from entering the upper part of the purification device 2 from the connection between the blocking cover 21 and the purification device installation groove 8, thereby improving the waterproof performance of the upper part of the purification device 2. In addition, the blocking cover 21 adopts the above-mentioned structure, so there is no need to set an upper cover on the purification device 2, which can reduce the production cost of the purification device 2, and there is no need to consider the fit between the upper end of the purification device 2 and the purification device installation groove 8, thereby reducing the requirements for the installation accuracy of the purification device 2.

[0112] The position of the electrode assembly hole 87 is higher than the position of the drain port 12 of the water tank 1 .

[0113] A drain port 12 is provided on the side wall of the water tank 1 , and the drain port 12 is connected to an external drainage pipe.

[0114] This arrangement ensures that the water level in the water tank 1 is always lower than the through-holes for installing the electrode terminals on the purification device 2, thereby preventing water from soaking the electrode terminals of the purification device 2. On the one hand, it solves the problem of water leakage caused by poor sealing. On the other hand, it prevents water from soaking through the electrode assembly holes 87 and contacting the electrode terminals of the purification device 2, causing leakage accidents, thereby ensuring the safety of the food purification equipment.

[0115] See also Figures 3 to 7 , and also includes a water inlet mechanism (not shown in the figure), the water inlet mechanism includes a water supply device and a water level monitor, the water inlet of the water supply device is connected to the external water supply pipeline, and the water outlet of the water supply device is arranged in the purification device installation groove 8; the water level monitor is arranged in the water tank 1, and is used to monitor the water level in the water tank 1.

[0116] The water supply device is a water supply pump.

[0117] Specifically, in order to simplify the structure of the water tank 1, the water level monitor is arranged in the purification device installation groove 8. A water inlet hole 90 is arranged in the purification device installation groove 8 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 12 is located, and the water level monitor installation hole 91 is located below the plane where the water drain port 12 is located, and the water inlet hole 90 and the water level monitor installation hole 91 are arranged corresponding to the air avoidance hole 27 of the purification device 2.

[0118] By providing the water inlet mechanism, it is convenient for the user to realize automatic water inlet of the water tank 1 by controlling the opening and closing of the water supply device, thereby improving the degree of automation of the water tank 1 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 8, and there is no need to open another hole on the water tank 1, 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 8, 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 2, thereby increasing the flow speed and external diffusion speed of the water body in the purification device 2 while reducing energy consumption. On the other hand, the water body input into the water tank 1 flows into the water tank 1 only after being purified by the purification device 2. Compared with the water body input into the water tank 1 flowing a certain distance before entering the purification device 2, the purification efficiency can be improved and the time required for purifying food can be shortened.

[0119] The purpose of adding a water inlet mechanism in the present embodiment is to realize automatic water inlet into the water tank 1, 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 1 can be directly filled with water using a faucet. Therefore, food purification equipment without a water inlet mechanism also falls within the protection scope of the present invention.

A water body driving device 7 is provided at the rear side of the purification device installation slot 8 corresponding to the rear opening 260 of the purification chamber 261; when the purification device 2 is installed in the purification device installation slot 8, the water body driving device 7 is located in the purification chamber 261.

[0123] By providing a water driving device 7, the water in the purification device 2 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 7 can contact the external water through the baffle 21 provided with a mesh 23. When the purification device 2 is placed in the water tank 1, the water driving device 7 can drive the water in the water tank 1 to flow quickly, thereby improving the cleaning effect of the food purification equipment on the food.

[0124] The water driving device 7 and the air diffusion channel 64 jointly promote the exchange of water in the purification device 2 with water in the outside.

[0125] 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 .

[0126] The working part of the tubeless water pump is placed in the purification device 2, 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.

[0127] The purification device installation groove 8 is provided with an installation hole 88 corresponding to the water body driving device 7 , and the water body driving device 7 is communicated with the purification chamber 261 through the installation hole 88 .

[0128] Compared with the prior art, the food purification equipment of the present invention has the following beneficial effects:

[0129] (1) A food purification device of the present invention has a purification device installation groove 8 provided in a water tank 1, so that the purification device 2 can be quickly installed in the purification device installation groove 8, thereby eliminating the need to provide other sealing structures on the side wall of the water tank 1 to seal with the purification device 2. On the one hand, the processing difficulty of the water tank 1 can be effectively reduced, and the production cost can be reduced. On the other hand, the sealing performance of the food purification device can be effectively improved, and the water in the water tank 1 can be prevented from flowing out from the connection between the water tank 1 and the purification device 2, thereby improving the safety of the food purification device.

[0130] (2) The purification device installation slot 8 of the present invention can be installed as a separate product on any water tank 1 body provided with a through hole adapted thereto, thereby overcoming the problem that the purification device 2 cannot be applied to water tanks 1 of different specifications, increasing the applicable scope of the purification device 2, and reducing the installation and maintenance costs, which is convenient for the promotion and use of the purification device 2; and when the user needs to replace a water tank 1 of other specifications, the purification device 2 and the purification device installation slot 8 of the original water tank 1 can be disassembled, and the purification device installation slot 8 can be fixed to the new water tank 1 for the purification device 2 to be installed, thereby reducing the replacement cost of the new food purification equipment, realizing the recycling of the purification device 2 and the purification device installation slot 8, and reducing the waste of resources;

[0131] (3) The water catalyst mechanism 3 of the purification device 2 is connected to the external power source by passing through the electrode terminal of the upper part of the shell 26.
