Description

TECHNICAL FIELD

[0001] The present application relates to a fruit and vegetable cleaning device for cleaning fruit and vegetables. BACKGROUND

[0002] CN209219203U both disclose a household fruit cleaning device, which comprises a cleaning box for containing fruits, a rotating shaft is horizontally arranged in the cleaning box, and a brush strip is arranged on the rotating shaft. In use, the fruits to be cleaned and cleaning water are put into the cleaning box, a rotating handle is manually rotated to drive the rotating shaft to rotate the bristles of the brush strip, the fruits are rolled in the water, and the bristles clean the surface of the fruits. The existing defects are that: in the cleaning box, when the brush rotates, the fruits are close to the wall surface of the cleaning box due to the centrifugal force, the fruits with large density (relative to water) will sink at the edge of the bottom of the cleaning box, and the fruits with small density (relative to water) will float at the edge of the water surface in the cleaning box, most of the fruits are thrown away from the brush, only a small part of the fruits can be contacted with the brush to be cleaned, therefore, the cleaning of the household fruit cleaning device is not uniform, especially when the amount of fruits is small, no fruits can contact the rotating brush, no fruits are cleaned by the brush, and the cleaning effect is poor; in addition, the amount of fruits that can be cleaned by the household fruit cleaning device is limited, if a large amount of fruits is to be cleaned, the volume of the cleaning box needs to be increased accordingly, and the size of the brush also needs to be increased.

[0003] CN104287650A discloses a fruit cleaning basket, which comprises a containing box and a disturbance cleaning device, the disturbance cleaning device comprises a handle, a U-shaped connecting rod and a cleaning roller, in use, clean water is filled into the containing box, fruits to be cleaned are put into the containing box, the handle is rotated, the cleaning roller can continuously disturb the fruits to be cleaned, and the bristles on the upper part of the cleaning roller can clean stains and residual pesticides on the surface of the fruits. The existing defects are that: in the disturbance cleaning device, the horizontally arranged cleaning roller can only disturb / push the fruits on the path along the circular arc path, the fruits will be concentrated to the corner part of the disturbance cleaning device, the cleaning of the fruits is chaotic and disordered, for the fruits with large density (relative to water) and large volume, the disturbance of the cleaning roller is easy to cause the fruits to be knocked, and for the fruits with large density (relative to water) and small volume, most of the fruits at the bottom of the disturbance cleaning device will not be disturbed, and the cleaning effect is poor. Similarly, the amount of fruits that can be contained in the disturbance cleaning device is limited, if a large amount of fruits is to be cleaned, the volume of the disturbance cleaning device needs to be increased accordingly, and the size of the cleaning roller also needs to be increased.

[0004] CN204104777U discloses a vegetable and fruit decontamination barrel, which comprises a cleaning barrel and a rotary cleaning device. A recess is arranged in the middle of the cleaning barrel along the center line direction of the cleaning barrel. The rotary cleaning device comprises a handheld rod, a U-shaped connecting rod and a longitudinal decontamination roller. The handheld rod is located above the barrel cover and is fixed to one end of the connecting rod. The decontamination roller is fixed to the other end of the connecting rod. The decontamination roller comprises a roller shaft and a roller brush. In use, clean water is filled into the cleaning barrel, and fruits to be cleaned are placed in the cleaning barrel. The decontamination roller can continuously disturb the fruits to be cleaned, and the bristles on the upper part of the decontamination roller can clean the stains and residual pesticides on the surface of the fruits. Compared with the fruit cleaning basket of CN104287650A, the fruit cleaning barrel only solves the problem that the fruits are concentrated at the corner of the disturbance cleaning device, and still has the problem of chaotic and disordered fruit cleaning. Moreover, the recess increases the risk of fruit bumping, and when cleaning a large amount of fruits, the decontamination roller is more likely to be jammed by the fruits.

[0005] CN105795492A, CN107280525A, CN108576866A and CN108813658A all disclose fruit cleaning devices, which comprise a container for containing fruits, and a brush vertically arranged in the container. In use, fruits are placed in the container, and water is injected into the container. The brush rotates self-rotation or rotates along the circumference of the container (CN108813658A), so as to generate a spiral water flow in the container. The fruits in the spiral water flow rotate in the container along with the water flow, and the brush brushes and cleans the relatively moving fruits. The disadvantages of the fruit cleaning device are as follows: the spiral water flow is generated by the self-rotation or circumferential rotation of the brush, the angular speed of the fruits in the spiral water flow is basically the same as that of the brush, and therefore, the relative motion between the brush and the fruits is very small, and the cleaning effect of the brush on the fruits is extremely limited. That is to say, the brush, water and fruits will rotate synchronously in the container, and the brush basically does not play a cleaning role on the fruits. Moreover, due to the centrifugal force, most of the fruits in the spiral water flow are thrown away to the side wall of the container, and only a small part of the fruits can be contacted with the brush to be brushed and cleaned, and the cleaning effect is poor. Similarly, the amount of fruits that can be contained in the container is limited. If a large amount of fruits needs to be cleaned, the volume of the container needs to be increased accordingly, and the size of the brush also needs to be increased.

[0006] CN209058078U discloses a fruit product cleaning device. Compared with CN108813658A, the stirring shaft with the brush rotates, and the fruits can be brushed and cleaned by relative motion. However, the structure is complex, and the fruit cleaning device can only be driven by electricity and cannot be manually operated. The cleaning of the fruits is still chaotic and disordered.

[0007] Therefore, the fruit cleaning device in the prior art has the following main deficiencies:

[0008] (1) the cleaning of fruits is uneven, chaotic and disordered, and uniform cleaning of fruits cannot be achieved;

[0009] (2) the capacity of the fruit cleaning container is limited, and if the cleaning capacity of fruits is to be increased, the volume of the fruit cleaning container and the size of the brush or cleaning roller need to be increased;

[0010] (3) the brush or cleaning roller is entirely immersed in water in the circumferential direction, and the rotating resistance is large, so that a large rotating force is required for rotation, and manual operation is laborious. SUMMARY

[0087] In the method of the present application, the input and output of fruits and vegetables are generally carried out in the fruit and vegetable flow temporary storage area. The fruits and vegetables are placed in the container, and water is injected into the container at the same time. The circulating driving mechanism drives the cleaning liquid to flow with the fruits and vegetables from the fruit and vegetable flow temporary storage area to the brushing zone, and then from the brushing zone to the fruit and vegetable flow temporary storage area, and so on, thereby forming a circulating flow path of fruit and vegetable flow temporary storage area-brushing zone-fruit and vegetable flow temporary storage area-brushing zone, and the circulating flow of the cleaning liquid drives the fruits and vegetables to circulate, and the brusher can brush the fruits and vegetables flowing through the brushing zone multiple times. When the fruits and vegetables are in the cleaning liquid, the cleaning liquid can soak the fruits and vegetables, which is beneficial to the cleaning of the dirt on the surface of the fruits and vegetables. When the flow speed of the fruits and vegetables and the cleaning liquid is different, the cleaning liquid can wash the surface of the fruits and vegetables. It should be noted that since the cleaning of the fruits and vegetables is carried out in sequence in the brushing zone, if the cleaning amount of fruits is to be increased, the present application only needs to increase the volume of the fruit and vegetable flow temporary storage area so that it can accommodate and soak more fruits to be cleaned, without changing the structure of the brushing zone and the brushing zone.

[0088] The present application has the following advantages:

[0089] 1. Under the action of the circulating driving mechanism, the fruits and vegetables can circulate in the circulating channel including the brushing zone and the fruit and vegetable flow temporary storage area, and the fruits and vegetables enter the brushing zone from the fruit and vegetable flow temporary storage area in sequence (for example, one by one or part by part), so that the brusher can clean all the fruits and vegetables in the circulating channel multiple times, and the cleaning is orderly and uniform, and there is no omission of fruits and vegetables, and there is no situation of uneven cleaning degree of fruits and vegetables.

[0090] 2. The process of washing fruits and vegetables in the container is as follows: Fruits and vegetables enter the washing zone from the flow storage area for washing, then flow back into the flow storage area. At the inlet and outlet of the flow storage area, there is a velocity difference between the washing liquid and the flow rate of the fruits and vegetables. The washing liquid rinses the fruits and vegetables. The fruits and vegetables then re-enter the washing zone for washing, and this cycle repeats. During this process, washing and rinsing alternate, so the fruits and vegetables are not only washed but also rinsed by the washing liquid. Furthermore, any residue remaining on the fruits and vegetables after rinsing is more easily removed in the washing zone.

[0091] 3. The volume of the fruit and vegetable flow storage area determines the maximum amount of fruit and vegetables that the fruit and vegetable washing device can wash at one time. Therefore, by adjusting the volume of the flow storage area, different quantities of fruit and vegetables can be washed without adjusting the size and structure of the washing area. Furthermore, the loading and unloading of fruit in the fruit and vegetable washing device typically takes place within the flow storage area.

[0092] 4. When the fruit and vegetable washing device is washing fruits, the fruits and vegetables flow sequentially with the washing liquid in the circulation channel, and there is less collision between fruits and vegetables and between fruits and vegetables and containers, which can reduce damage to fruits and vegetables during the washing process.

[0153] The invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0154] As described herein, the term "comprising" and its variations can be understood as open-ended terms, meaning "including but not limited to". The term "one embodiment" and similar expressions can be understood as "at least one embodiment". The terms "first", "second", etc., are used only to distinguish different features and have no substantive meaning. The terms "above", "below", and similar expressions are used only to indicate positional relationships between relative objects.

[0155] Reference Figures 1-51 A method for cleaning fruits and vegetables, which uses a fruit and vegetable cleaning device to clean fruits and vegetables, the fruit and vegetable cleaning device including a container 1, a circulation drive mechanism and a scrubber 2.

[0156] The container 1 has a circulation channel, which includes a connected fruit and vegetable flow storage area 3 and a washing area 4. When washing fruits and vegetables, the circulation channel can provide a path for the circulation of washing liquid and fruits and vegetables.

[0157] The scrubber 2 is disposed in the scrubbing area 4, and can scrub the fruits and vegetables as they pass through during washing. In one embodiment, see [reference needed]. Figure 2 In the given example, when the scrubber 2 is mounted horizontally on the container 1 with its rotating axis horizontally positioned, the container space corresponding to the orthographic projection area of ​​the rotating outer contour of the scrubber 2 onto the bottom of the container 1 is the scrubbing area 4. That is, the space area formed by the upward and downward projection of the rotating outer contour of the scrubber 2 relative to the container 1 is the scrubbing area 4 of the container 1. In another embodiment, see [reference needed]. Figure 3 and Figure 4 The given example or Figure 5 and Figure 6 In the given example, when the scrubber 2 is structured with a cleaning agent 9 disposed on the side and / or bottom of the container 1, the spatial area where the cleaning agent 9 is located corresponds to the scrubbing area 4. Those skilled in the art will understand that the structure of the scrubber 2 in this embodiment of the invention is not limited to... Figures 2 to 6 The examples given are sufficient to scrub the fruits and vegetables that pass through. Based on the foregoing description, those skilled in the art will understand the meaning of the scrubbing area described in the embodiments of the present invention.

[0158] The circulating drive mechanism provides driving force to drive the cleaning liquid and fruits and vegetables to circulate in the circulation channel during washing, sequentially passing through the scrubbing area for washing. In one embodiment, the sequential passage can be one fruit and vegetable passing through individually or multiple fruits and vegetables passing through together. Those skilled in the art will understand that the actual sequential passage during fruit and vegetable washing is affected by factors such as the size and quantity of the fruits and vegetables. When the fruits and vegetables are large, they are generally likely to pass through one by one; when the fruits and vegetables are small, multiple fruits and vegetables are generally likely to pass through together, although it is also possible for them to pass through one by one.

[0159] In one embodiment, the circulation drive mechanism can employ a rotating impeller 5. The rotation of the impeller 5 drives the cleaning liquid to circulate, thereby driving the circulation of fruits and vegetables. Of course, other mechanisms known to those skilled in the art can also be used, as long as they can drive the cleaning liquid and fruits and vegetables to circulate in the circulation channel. The circulation drive structure can be disposed on the side wall of the container 1, either on one side wall or on multiple side walls to allow for smoother and more efficient flow of the cleaning liquid. Furthermore, it can be disposed on two adjacent or opposite side walls, or on any three side walls, or even on each side wall; and each side wall can have one or more rotating impellers 5. Those skilled in the art will understand that the driving force provided by each rotating impeller 5 is in the same direction. Of course, in some embodiments, it is also feasible for the driving force direction of individual rotating impellers 5 to be inconsistent with the driving force direction of other rotating impellers 5. Figure 3 and Figure 4 The given example, or Figure 5 and Figure 6 In the given example, the circulation drive mechanism uses a rotating impeller 5. To allow the cleaning fluid to flow more smoothly and effectively, the rotating impeller 5 can be installed on at least two side walls of the container 1. In one embodiment, refer to... Figure 3 and Figure 4 As shown, or you can refer to Figure 5 and Figure 6 As shown, rotating impellers 5 can be installed on opposite side walls of the container. The rotation direction of the rotating impeller 5 on one side wall is opposite to that on the other side wall, so that the driving force provided by the rotating impellers 5 on each side wall is in the same direction. At the same time, in order to protect the fruits and vegetables and prevent them from being hit by the rotating impellers 5, a protective shell 6 needs to be installed outside the rotating impellers 5.

[0160] In one embodiment, when the fruit and vegetable washing device is provided with a partition 10, the circulation drive mechanism can also be provided on the partition 10.

[0161] The fruit and vegetable cleaning device provided by the embodiment of the present application is used to put fruits or vegetables into the container 1 (for vegetables with large shapes or irregular shapes, the vegetables need to be changed into small ones before being put into the container 1, for example, the vegetables are changed into small ones by hand or by a knife), generally, since the brusher 2 placed in the brushing area 4 occupies the holding space of the brushing area 4, when the fruits and vegetables are prepared to be cleaned, the fruits and vegetables are generally put into the fruit and vegetable flowing temporary storage area 3 first, when the container 1 holds the cleaning liquid (the cleaning liquid can be water, other liquid or a mixture of other substances and water), under the action of the circulating driving mechanism, the cleaning liquid drives the fruits and vegetables to flow from the fruit and vegetable flowing temporary storage area 3 to the brushing area 4, and then to the fruit and vegetable flowing temporary storage area 3, so as to form a circulating flow path of the fruit and vegetable flowing temporary storage area 3-brushing area 4-fruit and vegetable flowing temporary storage area 3 in the circulating channel. When the fruits and vegetables flow through the brushing area 4 along with the cleaning liquid, the brusher 2 rubs against the fruits and vegetables, so as to realize the brushing of the fruits and vegetables; when the fruits and vegetables are in the cleaning liquid, the cleaning liquid can soak the fruits and vegetables, which is beneficial to the cleaning of the dirt on the surface of the fruits and vegetables; when the flow speed of the fruits and vegetables is different from that of the cleaning liquid, the cleaning liquid can wash the surface of the fruits and vegetables. The fruits and vegetables can enter the brushing area one by one or in parts (i.e. in order) when entering the brushing area from the fruit and vegetable flowing temporary storage area 3, the brusher 2 cleans the fruits and vegetables in order, and the cleaning is uniform, orderly and good in effect. When the fruits and vegetables are cleaned in the container 1, the fruits and vegetables experience the process of brushing in the brushing area 4-washing in the fruit and vegetable flowing temporary storage area 3-brushing in the brushing area 4 again, and the brushing and washing are intermittently performed during the cleaning, the fruits and vegetables can be not only brushed but also washed by the cleaning liquid, and the garbage remaining on the fruits and vegetables after the soaking and washing is more easily brushed away by the brusher 2 in the brushing area 4, and the above beneficial effects are produced by the synergistic action of the three factors that the container 1 has the fruit and vegetable flowing temporary storage area 3 and the brushing area 4 which are communicated, the brushing area 4 has the brusher 2, and the circulating driving mechanism provides the driving of the cleaning liquid and the fruits and vegetables to circulate and flow in the circulating channel.

[0162] Meanwhile, since the container of the present application has the communicating brushing area 4 and the fruit and vegetable flow temporary storage area 3, the fruits and vegetables are brushed by the brusher 2 in the brushing area 4 and flow with the cleaning liquid in the fruit and vegetable flow temporary storage area 3 during the cleaning, and the fruits and vegetables are not strongly agitated and the collision between the fruits and vegetables and between the fruits and vegetables and the container is small during the whole process. Since the fruits and vegetables flow in the container 1 during the cleaning, the fruits and vegetables can be put in the container 1 according to the capacity of the fruit and vegetable flow temporary storage area 3, as long as the cleaning of the fruits and vegetables is not affected. In the embodiment of the present application, the fruits and vegetables are put in the fruit and vegetable cleaning device in the fruit and vegetable flow temporary storage area 3, and the above description is based on the example that the fruits and vegetables are put in the fruit and vegetable flow temporary storage area 3 before the cleaning. Of course, it is also possible that part of the fruits and vegetables or all of the fruits and vegetables are put in the brushing area 4 before the cleaning, and the person skilled in the art can know the working mode of this case according to the above description, for example, the embodiment shown in Figure 5 and Figure 6 , the fruits and vegetables put in the brushing area 4 flow from the brushing area 4 to the fruit and vegetable flow temporary storage area 3 under the driving of the cleaning liquid, and then flow from the fruit and vegetable flow temporary storage area 3 to the brushing area 4, so that a circulation flow path of brushing area 4-fruit and vegetable flow temporary storage area 3-brushing area 4 is formed in the circulation channel, and other related contents can be referred to the above description, which will not be described here. In the embodiment of the present application, the fruits and vegetables are usually taken out in the fruit and vegetable flow temporary storage area 3, so as to avoid the blockage of the brusher 2 placed in the brushing area 4. Of course, the embodiment of the present application also does not exclude the case of taking out from the brushing area 4.

[0163] In one embodiment, one structure form of the brusher is (hereinafter referred to as A form brusher): as shown in Figure 3 , Figure 4 , the brusher comprises a back plate 7 and a brushing object 8 provided on the first surface of the back plate 7, and the brushing object 8 is preferably arranged towards the bottom of the container 1. The brushing object 8 can be a plastic flexible cleaning object, or a soft rubber flexible cleaning object, or a cloth strip flexible cleaning object, or other flexible brushing components. In order to enhance the brushing effect, the brushing object 8 can also be arranged on the bottom surface of the brushing area 4 of the container. The brushing object 8 on the first surface of the back plate 7 is in contact with or has a gap with the brushing object 8 on the bottom surface of the brushing area 4.

[0164] In another embodiment, one structure form of the brusher is (hereinafter referred to as B form brusher): as shown in Figure 5 , Figure 6 , the brusher is a cleaning object 9 arranged on the side and / or bottom surface of the container 1. The cleaning object 9 can be a plastic flexible cleaning object, or a soft rubber flexible cleaning object, or a cloth strip flexible cleaning object, or other flexible brushing components. In the following, the container has a barrier 10, and the cleaning object 9 can also be arranged on the barrier 10.

[0165] In another embodiment, the scrubbing device has the following structural form (hereinafter referred to as the C-type scrubbing device): See reference... Figure 2 As shown, the scrubber includes a rotating shaft 11 and a scrubbing part 12 disposed on the rotating shaft 11. The scrubbing part 12 extends away from the rotating shaft 11, allowing fruits and vegetables to pass between the scrubber 2 and the bottom surface of the container 1 when circulating in the circulation channel, thus achieving scrubbing. In this configuration, the scrubber 2 is positioned horizontally in the container 1 with the rotating shaft 11 horizontally positioned. "Horizontally positioned rotating shaft" means that the rotating shaft 11 is essentially horizontally positioned, that is, the axis of the rotating shaft 11 is basically parallel to the horizontal plane. Even if the axis of the rotating shaft 11 forms a certain angle with the horizontal plane, it still falls within the meaning of "horizontally positioned rotating shaft" as used in this embodiment of the invention. Because of the rotating shaft 11, the scrubber 2 can rotate around the rotating shaft 11 as its central axis. Therefore, the scrubber 2 constitutes the circulation drive mechanism. When cleaning fruits and vegetables, the scrubber 2 can be rotated to provide the driving force that drives the cleaning liquid and fruits and vegetables to circulate in the circulation channel.

[0166] When using a C-type scrubber, the form of the rotating shaft can be varied. For example, it can be a single shaft, or the rotating shaft can include a main shaft 45 and a bushing 46 mounted on the main shaft 45. The scrubbing part 12 is mounted on the bushing 46. The connection between the main shaft 45 and the bushing 46 can be a snap-fit ​​connection, a threaded connection, an interference fit, etc. The main shaft 45 is usually made of metal, and the bushing 46 is usually made of plastic. In this case, the connection between the main shaft 45 and the bushing 46 can also be as follows: the end of the main shaft 45 has teeth 47 to form a rough part, and the bushing 46 is fitted onto the main shaft 45. The rough part of the main shaft 45 and the bushing 46 fit tightly together, causing the corresponding parts of the bushing 46 and the rough part of the main shaft 45 to deform to a certain extent, thereby tightly connecting the main shaft 45 and the bushing 46 to form a rotating shaft assembly.

[0167] When using a C-type scrubber, there can be only one scrubber 2, or multiple scrubbers can be arranged side by side, and the scrubbing area 4 is arranged corresponding to the scrubber 2. For example... Figure 7 , Figure 8 As shown, multiple scrubbers 2 can be linked together, allowing them to rotate synchronously. The linkage mechanism between the multiple scrubbers can be a gear drive mechanism, chain drive mechanism, belt drive mechanism, etc. Figure 7 , Figure 8 The linkage mechanism shown is a gear transmission mechanism. Figure 7 , Figure 8Two brushers 2, two brushers 3 of the rotation shaft are equipped with passive gear 13, two passive gear 13 are equipped with transition gear 14, through the effect of transition gear 14 make two brushers on rotation shaft 11 synchronous rotation, two brushers 2 need to rotate when transition gear 14 rotates, thereby drive two rotation shaft 11 synchronous rotation, transition gear 14 can be driven by the drive mechanism described later. When the brusher is multiple, the brusher corresponds to the brusher one by one, each brusher is sequentially arranged or spaced. Or, the brusher is one or more, and each brusher is provided with one or more brushers.

[0168] When the brusher is in the form of C, the brusher can also be provided as shown in the figure, the brusher 2 includes the first brusher 2-1 and the second brusher 2-2 arranged oppositely, thereby forming two opposite brusher areas 4, improving the cleaning efficiency. The first brusher 2-1 and the second brusher 2-2 are preferably connected by a reversing mechanism to make the rotation directions of the first brusher 2-1 and the second brusher 2-2 opposite, so that the cleaning liquid forms a smooth circulating flow in the circulating channel. The reversing mechanism can adopt the form of a common reversing mechanism, for example, the rotation shaft of the first brusher 2-1 is equipped with a first double gear, and the rotation shaft of the second brusher 2-2 is equipped with a second double gear, and the first double gear and the second double gear are engaged. Figure 9

[0169] The brusher 2 is preferably detachably arranged on the container 1 to facilitate replacement of the brusher 2 or removal of the brusher 2 for cleaning. When the brusher is in the form of C, the detachable connection between the brusher 2 and the container 1 can be as shown in the figure, the rotation shaft 11 of the brusher is arranged between the stop block 15 and the upper edge of the container 1, and the stop block 15 and the container 1 are fixed by screws. When disassembled, the screws can be unscrewed. Or as shown in the figure, the rotation shaft 11 of the brusher is directly arranged on the upper end of the container, and when disassembled, it can be removed. As described later, when the container 1 is provided with a barrier 10, the end of the rotation shaft 11 of the brusher can be connected to the barrier 10. In order to achieve detachability, the end of the rotation shaft 11 can be directly arranged on the barrier 10, or a second stop block 16 is arranged on the upper edge of the barrier 10, and the rotation shaft 11 of the brusher is arranged between the second stop block 16 and the upper edge of the barrier 10. The second stop block 16 and the barrier 10 are fixed by screws. When disassembled, the screws can be unscrewed. Of course, the brusher and the container can also adopt other detachable connection modes, for example, a positioning block is arranged on the rotation shaft, and the positioning block and the container are connected by buckling or screws. Figure 13 14 Figure 2

[0170] ​​​​The corners of the container 1 are preferably designed as arc-shaped chamfers. If the corners of the container 1 are designed as sharp corners, dirt accumulated at the corners of the container 1 is not easy to clean. Meanwhile, if the corners of the container 1 are all designed as arc-shaped chamfers, fruits and vegetables are not easy to be damaged when they flow with the cleaning liquid. Meanwhile, the cleaning liquid flowing in a circulating manner is also less likely to lose kinetic energy at the corners of the container 1 due to the fact that it flows along the arc-shaped surface.

[0171] As a preferred design, the bottom surface of the fruit and vegetable flow temporary storage area 3 is provided with a slope 17. When the fruits and vegetables flow from the brushing area 4 into the fruit and vegetable flow temporary storage area 3, they flow from the high position of the slope 17 to the low position of the slope 17 to accelerate the flow of the fruits and vegetables, so as to avoid congestion of the fruits and vegetables in the fruit and vegetable flow temporary storage area 3.

[0172] When the C-shaped brusher is used, in order to enable the brusher to rotate, the rotating shaft or the brusher can be held to rotate, so that the brushing area rotates. Of course, a better way is that the rotating shaft 11 is connected with a driving mechanism for driving the rotating shaft 11 to rotate, so that the brusher 2 rotates. The driving mechanism can be an electric driving mechanism or a manual driving mechanism. The driving mechanism is generally located outside the container, so as to be convenient for operation. The electric driving mechanism is for example a motor, and the output end of the motor is connected with the rotating shaft. The manual driving mechanism is for example a crank 18, and the end of the crank 18 is connected with the rotating shaft 11. The distance between the bottom surface of the container 1 and the crank 18 in the lowest position is preferably controlled to be 1.5 cm to 8 cm, so that a space for accommodating the hand is formed between the crank 18 in the lowest position and the table top when the crank 18 is shaken, and the hand holding the crank 18 does not touch the table top when the crank 18 is shaken.

[0173] The connection between the crank 18 and the rotating shaft 11 can be direct connection or connection through a connecting structure, for example, connection through a gear transmission mechanism.

[0174] The driving mechanism is preferably detachably connected with the container 1, so as to be detached together with the brusher 2 for packaging, thereby saving the packaging space.

[0175] When the driving mechanism is an electric driving mechanism, the detachable connection between the electric driving mechanism and the container can adopt buckle connection, screw connection or other ways, or can adopt the way that a sliding groove is arranged on the container and a sliding piece is arranged on the driving mechanism, and the sliding piece is inserted into the sliding groove.

[0176] When the driving mechanism is a manual driving mechanism, the detachable structure between the driving mechanism and the container can be buckle connection, screw connection or other ways, or can adopt the way that a sliding groove is arranged on the container and a sliding piece is arranged on the driving mechanism, and the sliding piece is inserted into the sliding groove.

[0177] Another way to achieve the detachable connection between the driving mechanism and the container is that since the driving mechanism is connected with the rotating shaft 11, only the detachable connection between the rotating shaft 11 and the container 1 is needed, and the detachable connection between the rotating shaft 11 and the container is as described above.

[0178] The detachable connection between the driving mechanism and the rotating shaft 11 can also be achieved, so that the driving mechanism can be detached alone. The simplest way to achieve the detachable connection between the driving mechanism and the rotating shaft 11 is that the end of the rotating shaft 11 is polygonal in cross section, and the output end of the driving mechanism is provided with a shaft sleeve which is a sleeve matching the shape of the end of the rotating shaft 11. The end of the rotating shaft 11 is inserted into the shaft sleeve to achieve the detachable connection between the rotating shaft and the driving mechanism, and the driving mechanism can smoothly drive the rotating shaft to rotate.

[0179] The detachable connection mechanism between the driving mechanism and the rotating shaft 11 can also be achieved in other ways, for example, as shown in Figures 15-21 , the rotating shaft 11 is provided with a driven gear 28, the output end of the handle 18 is provided with a driving gear 19, the driving gear 19 and the driven gear 28 on the rotating shaft 11 are engaged, a gear cavity 20 is provided on the upper end of the container 1, the driving gear 19 and the driven gear 28 on the rotating shaft 11 are arranged in the gear cavity 20 (all or part), and the detachable connection between the driving gear 19 and the handle 18 is achieved. In Figure 15 , 16 , the detachable connection between the driving gear 19 and the handle 18 is achieved in the following way: the driving gear 19 has a disassembly cavity 21, the disassembly cavity 21 is provided with a blocking rib 23, the end of the handle 18 is provided with a protruding rib 22, the end of the handle 18 is inserted into the disassembly cavity 21, and the handle 18 is rotated to make the protruding rib 22 abut against the blocking rib 23. Thus, the handle 18 can drive the driving gear 19 to rotate, and the handle 18 can be detached by being pulled out of the gear cavity 20. Figure 17 , 18 , in the driving gear 19 and the handle 18, the detachable connection between the driving gear 19 and the handle 18 is achieved in the following way: the driving gear 19 has a cavity 24, the cavity 24 is provided with a screw rod 25, the screw rod 25 is inserted into the handle 18, and a locking rod 26 is also inserted into the cavities of the handle 18 and the driving gear 19, the locking rod 26 has a threaded cavity 27, the screw rod 25 is screwed into the threaded cavity 27, and the end of the locking rod 26 is locked on the handle 18. Thus, the connection between the handle 18 and the driving gear 19 is achieved, and the handle 18 can be detached by unscrewing the locking rod 26 when disassembly is needed.

[0180] The detachable connection mechanism between the driving mechanism and the rotating shaft 11 can also be achieved in other ways, for example, as shown in Figures 52-60 , in Figures 52-60As previously described, the rotating shaft 11 includes a main shaft 45 and a bushing 46 mounted on the main shaft 45. A driven gear 28 is mounted on the main shaft 45, located at the outer end of the main shaft 45. The threads 47 on the main shaft 45 are located at the inner end of the main shaft 45. A crank handle 18, serving as the driving mechanism, has a drive shaft 48 at one end. A drive gear 19 is mounted on this drive shaft 48. The drive shaft 48 passes through a drive fixing block 49, allowing it to rotate. The drive gear 19 meshes with the driven gear 28. Rotating the crank handle 18 drives the driven gear 28 via the drive gear 19, thereby rotating the rotating shaft 11. Figure 58 , 59 As shown, the driven gear 28 can be a common gear with only one ring of teeth. In this case, the driving gear 19 drives the driven gear 28, which in turn drives the main shaft of the rotating shaft 11 to rotate, thus allowing the entire rotating shaft 11 to rotate. Simultaneously, a gear ring 50 can be provided inside the bushing 46. Part of the driven gear 28 meshes with the driving gear 19, and another part of the driven gear 28 also meshes with the gear ring 50 of the bushing 46. Figures 53-60 As shown, the driven gear 28 can also be a double gear. The first stage of the double gear meshes with the driving gear 19. A gear ring 50 is provided inside the bushing 46, and the second stage of the double gear meshes with the gear ring 50. When the above mechanism is used, one end of the bushing 46 is tightly engaged with the main shaft 45 through the action of the toothed thread 47, and the other end of the bushing 46 meshes with the driven gear 28. That is, both ends of the bushing 46 are positioned, making the bushing 46 more stable when rotating. A gear cavity 20 is provided at the upper end of the side wall of the container 1. The driving gear 19 and the driven gear 28 are both located in the gear cavity 20 (the driven gear 28 can be fully or partially located in the gear cavity 20). The driving fixing block 49 is detachably installed in the gear cavity 20. The driving fixing block 49, the driving gear 19, and the driving shaft 48 form an assembly. The entire assembly is detachable. When disassembly is required, only the driving fixing block 49 needs to be removed. Installation is also very convenient; only the driving fixing block 49 needs to be installed into the gear cavity 20. The detachable connection of the drive fixing block 49 can take many forms, such as setting a positioning rib 51 in the gear cavity 20 and setting a positioning groove 52 on the drive fixing block 49, with the positioning rib 51 inserted into the positioning groove 52 to position the drive fixing block 49; or the drive fixing block 49 can be connected to the side wall of the container by a screw, preferably the screw passing through the upper end of the drive fixing block 49; or the drive fixing block and the cavity wall of the gear cavity 20 can be connected by a snap-fit ​​connection, etc.

[0181] The main shaft 45 of the rotating shaft 11 can be inserted into the side wall of the container, or can be positioned in the following manner: a lower main shaft groove 53 is provided on the bottom surface of the gear cavity 20, one end of the main shaft 45 is supported in the lower main shaft groove 53, the lower end of the driving fixed block 49 is provided with an upper main shaft groove 54, and when the driving fixed block 49 is installed into the gear cavity 20, the upper main shaft groove 54 is pressed on the main shaft 45, at this time the upper main shaft groove 54 and the lower main shaft groove 53 surround the main shaft 45 to form a shaft hole. The other end of the main shaft 45 can be suspended, and when the barrier 10 is arranged in the container, a lower main shaft auxiliary groove 55 can be arranged on the upper end surface of the barrier 10, and the other end of the main shaft 45 is arranged in the lower main shaft auxiliary groove 55, and a second stop block 16 is arranged on the upper end of the barrier 10, and the second stop block 16 is provided with an upper main shaft auxiliary groove, and when the second stop block 16 is installed on the barrier 10, the lower main shaft auxiliary groove and the upper main shaft auxiliary groove surround the main shaft 45 to form a shaft hole. After the above installation method is adopted, the driving shaft 48 is arranged in the driving fixed block 49, and the main shaft 45 of the rotating shaft is pressed between the driving fixed block 49 and the gear cavity 20, so that the part of the side wall of the container 1 corresponding to the main shaft 45 is not provided with an opening, thereby improving the liquid capacity of the container 1 and eliminating the risk of liquid leakage caused by the direct opening of the side wall corresponding to the main shaft 45. At the same time, the driving shaft 49 is generally located above the main shaft 45 of the rotating shaft 11, so that the handle 18 connected with the driving shaft 49 is located at a high position, which facilitates the rotation of the handle 18 and avoids the hand holding the handle 18 from hitting the table top when the handle 18 is rotated.

[0182] In addition, a wear-resistant mechanism can be arranged on the driving shaft 48, and the wear-resistant mechanism can be a driving shaft protective sleeve 56 (usually a rubber sleeve), which is arranged between the driving shaft 48 and the driving fixed block 49 and is used to reduce the friction between the driving shaft 48 and the driving fixed block 49 during rotation. A wear-resistant mechanism can also be arranged on both ends of the main shaft 45 of the rotating shaft, and the wear-resistant mechanism can be a rotating shaft protective sleeve 57 (usually a rubber sleeve), which is arranged in the shaft hole and is used to reduce the friction between the main shaft 45 of the rotating shaft and the shaft hole during rotation. Of course, the detachable connection between the rotating shaft and the driving mechanism can also be threaded connection, screw connection, gear engagement connection, etc.

[0183] A speed regulation mechanism can be arranged between the driving mechanism and the rotating shaft 11. The speed regulation mechanism can be a speed increasing mechanism (for example, a gear train speed increasing mechanism, as shown in Figure 20 , 21 When the speed regulation mechanism is a speed increasing mechanism, the rotating speed of the rotating shaft can be increased to achieve higher efficiency of brushing;

[0184] The speed regulating mechanism can be a speed reducing mechanism (for example, a gear train speed reducing mechanism), and when the speed regulating mechanism is a speed reducing mechanism, the rotating speed of the rotating shaft can be reduced, and in this case, the rotation of the brush washer can be more relaxed;

[0185] The speed regulating mechanism can be a gearbox (i.e., a gear shifting gearbox, which is consistent with the principle of a manual transmission gearbox of an automobile, and different gears are outputted by shifting gears, so as to achieve the purpose of speed regulation), and when the speed regulating mechanism is a gearbox, the rotating speed of the rotating shaft can be increased or reduced according to the actual use.

[0186] The size relationship between the brush washing area 4 and the fruit and vegetable flow temporary storage area 3 can be: (1) the available volume of the fruit and vegetable in the brush washing area 4 is less than the available volume of the fruit and vegetable in the fruit and vegetable flow temporary storage area 3, so that more fruits can be placed in the fruit and vegetable flow temporary storage area 3, and at the same time, the fruits in the brush washing area 4 can also be controlled within a certain range, so as to ensure that the fruits pass through the brush washing area 4 smoothly and prevent congestion of too many fruits when passing through the brush washing area 4. The "available volume of the fruit and vegetable in the brush washing area" referred to herein refers to the volume of the fruits that can be accommodated in the brush washing area 4 under normal cleaning conditions, that is, the volume remaining after the volume occupied by the brush washer 2 in the brush washing area 4 is removed. (2) the maximum cross-sectional area of the brush washing area 4 is less than or equal to the minimum cross-sectional area of the fruit and vegetable flow temporary storage area 3, and in this case, the shapes of the brush washing area 4 and the fruit and vegetable flow temporary storage area 3 can be irregular shapes. (3) both of the above two cases exist.

[0187] When the C-shaped brush washer is used, the cleaning liquid preferably flows along the side wall of the container 1 in the direction of rotation of the brush washer 2 to drive the cleaning liquid to circulate, so that the cleaning liquid does not impact the side wall of the container 1 obliquely to lose the driving force for advancing. Therefore, the axis of the rotating shaft 11 is preferably substantially perpendicular to the flow direction of the cleaning liquid in the container 1. The "perpendicular" referred to herein refers to the engineering sense of substantially perpendicular, which falls within the scope of perpendicular within a reasonable angle, and does not require absolute perpendicular in the geometric sense. Figure 10 11 As shown in FIG. 12, the rotating shaft 11 is not absolutely perpendicular to the flow direction of the cleaning liquid, but the obliquely arranged rotating shaft 11 can still drive the cleaning liquid in the container 1 to flow in the circulation channel when rotating, and the flow direction of the cleaning liquid is also substantially along the side wall of the container. Figure 10 11 The connection between the rotating shaft 11 and the handle 18 in FIG. 12 can adopt two ways. One is shown in FIG. Figure 10 11 The output end of the handle 18 is provided with a bevel gear 45, and the rotating shaft 11 is provided with a driven gear 28. The bevel gear 45 and the driven gear 28 are engaged, and the rotation of the handle 18 drives the brush washer 2 to rotate. In this case, the rotation axis of the output end of the handle 18 is still parallel to the horizontal plane, and the handle 18 is more comfortable to operate when rotating. The other way is shown in FIG. Figure 12 ​​​The handle 18 is directly connected to the rotating shaft 11, and the rotating shaft of the output end of the handle 18 is coaxial with the rotating shaft 11, which is simple to install but slightly inconvenient to operate.

[0188] When the C-shaped brusher is adopted, the brusher 12 comprises a plurality of rows of first flexible cleaning objects 29 distributed along the axial direction of the rotating shaft 11, and the first flexible cleaning objects 29 are plastic flexible cleaning objects, soft rubber flexible cleaning objects, or cloth strip flexible cleaning objects. The aforementioned "distributed along the axial direction of the rotating shaft" means that the first flexible cleaning objects 29 are distributed along the axial direction of the rotating shaft, which can be vertically arranged or spirally arranged along the axial direction of the rotating shaft, and all of the above belong to the aforementioned "distributed along the axial direction of the rotating shaft". The above-mentioned regular arrangement mode can achieve better cleaning effect, and of course, the first flexible cleaning objects 29 can also be arranged in other irregular or regular modes. In the radial cross section of the brusher 2, the spacing between the first flexible cleaning objects 29 of adjacent two rows is preferably substantially equal.

[0189] The first flexible cleaning objects 29 can be bent, the first end of the first flexible cleaning objects 29 is arranged on the rotating shaft 11, and the second end of the first flexible cleaning objects 29 is a free end. When the fruits and vegetables pass through the brusher area 4, the fruits and vegetables are in contact with the first flexible cleaning objects 29, so that the first flexible cleaning objects 29 are bent, and the fruits and vegetables are brushed by the first flexible cleaning objects 29.

[0190] The specific formation mode of the first flexible cleaning objects 29 can be as shown in Figure 24 Each row of first flexible cleaning objects 29 can be a row of complete flexible cleaning objects, such as a complete plastic strip (such as a nylon strip, a TPR strip, etc.), a complete soft rubber strip (such as a silica gel strip, etc.), a complete cloth strip, etc.

[0191] The formation mode of each row of first flexible cleaning objects 29 can also be as shown in Figure 22 、 23 , 25, 26, which comprises a plurality of rows of rod-shaped objects (the cross section can be circular or directional or other shapes), such as a plurality of plastic rods (such as nylon rods, TPR rods, etc.) arranged to form a row of first flexible cleaning objects 29, a plurality of soft rubber rods (such as silica gel rods, etc.) arranged to form a row of first flexible cleaning objects 29, a plurality of plastic wires (such as nylon wires, TPR wires, etc.) arranged to form a brush, a plurality of brushes arranged to form a row of first flexible cleaning objects 29, a plurality of soft rubber wires (such as silica gel wires, etc.) arranged to form a soft brush, and a plurality of soft brushes arranged to form a row of first flexible cleaning objects 29, etc. Figure 22 The plurality of rows of rod-shaped objects are 6 rows as shown in Figure 23 The plurality of rows of rod-shaped objects are 10 rows as shown in Figure 25 And Figure 26 The plurality of rows of rod-shaped objects are 7 rows as shown in. The rod-shaped objects can be strips or other shapes, such asFigure 23 , Figure 25 and Figure 26 The strip shown Figure 22 The spiral shape.

[0192] When using a C-type scrubber, after the scrubber 2 is installed on the container 1, the distance between the scrubbing part 12 and the bottom surface of the container 1 is preferably 0.5mm-5cm. At this distance, the scrubbing part 12 does not contact the bottom surface of the container 1, making the rotation of the scrubber 2 easier. Alternatively, after the scrubber 2 is installed, the scrubbing part 12 contacts the bottom surface of the container 1. In this case, the debris deposited on the bottom surface of the container 1 can be swept away, achieving self-cleaning of the bottom surface of the container 1. With the above option, on the one hand, the scrubbing part 12 extends into the scrubbing zone 3, so when fruits and vegetables pass through the scrubbing zone 4, the friction between the fruits and vegetables and the scrubbing part is more sufficient, and more fruits and vegetables can rub against the scrubbing part 12, thus resulting in a better cleaning effect. On the other hand, the scrubbing part 12 extends into the scrubbing zone 4, which has a stronger driving effect on the cleaning liquid, thus making it easier to form a fast-flowing circulating water flow. The fast-flowing circulating water flow helps to drive the fruits and vegetables to circulate quickly, resulting in a better cleaning effect.

[0193] When using a C-type scrubber, after the scrubber 2 is installed, the scrubbing part 12 is preferably higher than the container 1. This arrangement ensures that only part of the scrubbing part 12 is immersed in the cleaning liquid when the scrubber 2 rotates. Therefore, the resistance of the cleaning liquid encountered by the scrubber 2 when rotating is relatively small, and the scrubber 2 does not require much effort to rotate.

[0194] When using the C-type scrubber 2, the preferred arrangement of the scrubbing parts 12 is that the scrubbing parts 12 are distributed almost evenly in the transverse width direction of the scrubbing area 4, so that the fruits and vegetables passing through the scrubbing area 4 can be scrubbed by the scrubbing parts 12, resulting in a better cleaning effect.

[0195] As a more optimized arrangement, the bottom of the container 1 is provided with a wiping component 30, which can be a flexible cleaning object (such as plastic bristles, plastic brush columns, soft rubber strips, soft rubber bristles, flexible cloth strips, etc.), convex strips or convex points, or other forms. In the direction of the cleaning liquid flow, the wiping component 30 can be located in front of the brusher 2, behind the brusher 2, below the brusher 2, or in front of, behind, and below the brusher 2, or in two of the front, back, and bottom of the brusher 2. The significance of setting the wiping component is that if the wiping component 30 is set in front of the brusher 2, the fruits and vegetables will be wiped by the wiping component 30 when they enter the brushing area 4; if the wiping component 30 is set behind the brusher 2, the fruits and vegetables will be wiped by the wiping component 30 when they flow out of the brushing area 4; if the wiping component 30 is set below the brusher 2, the fruits and vegetables will be wiped by the brushing component 12 and the wiping component 30 at the same time when they pass through the brushing area 4. Therefore, after setting the wiping component 30, the fruits and vegetables can not only be brushed by the brushing component 12, but also be rubbed between the brushing component 12 and the wiping component 30 to achieve better cleaning effect. Of course, the wiping component 30 can also be set in two or three of the front, back, and bottom of the brusher 2. In Figure 27 、 28 、29, the front, back, and bottom of the brusher 2 are all provided with the wiping component 30, in Figure 30 、 31 、32, the front of the brusher 2 is provided with the wiping component 30, in Figure 33 、 34 、35, the back of the brusher 2 is provided with the wiping component 30, in Figure 36 、 37 、38, the bottom of the brusher 2 is provided with the wiping component 30. In Figure 27 、 30 、33, 36, the wiping component is a convex point, in Figure 28 、 31 、34, 37, the wiping component is a soft rubber strip, in Figure 29 、 32 、35, 38, the wiping component is a short brush.

[0196] The wiping member 30 is preferably arranged at a position behind the brusher 2 in the direction of the flow of the cleaning liquid. Since the wiping member 30 is arranged at a position behind the brusher 2, the fruits and vegetables will not be subjected to extra resistance when entering the brushing area 4, and thus can enter the brushing area 4 smoothly. In addition, the wiping member 30 arranged at a position behind the brusher 2 will not generate extra resistance to the fruits and vegetables in the brushing area 4, and thus prevent the fruits and vegetables from being detained in the brushing area 4 due to the loss of the driving force. In addition, the wiping member 30 arranged at a position behind the brusher 2 will enable the fruits and vegetables to obtain the driving force from the brusher 12 when the fruits and vegetables are about to leave the brushing area 12 after being brushed by the brusher 12, and thus generate friction with the wiping member 30, and thus achieve better cleaning effect.

[0197] After the fruits and vegetables cleaning device is used for a period of time, the dirt removed by the cleaning will be deposited at the bottom of the container, and the wiping member 30 is arranged at the bottom of the container, and thus the dirt will be easily adhered to the wiping member 30. Therefore, the first flexible cleaning member 29 is preferably arranged in contact with the wiping member 30, so that the first flexible cleaning member 29 can brush the wiping member 30, and thus clean the wiping member 30.

[0198] In order to enhance the cleaning effect, a transition surface 31 gradually rising in the direction of the flow of the cleaning liquid can be formed on the bottom surface of the brushing area 4 or the bottom surface of the container at the outlet side of the brushing area 4. When the fruits and vegetables are brushed in the brushing area 4, the fruits and vegetables will climb along the transition surface 31, and thus the friction between the brushing area 12 and the fruits and vegetables will be enhanced, and thus the cleaning effect will be enhanced. The transition surface 31 is preferably in the form of an inclined surface or a concave arc surface, and more preferably in the form of a concave arc surface. The fruits and vegetables will climb in the concave arc surface, and thus the cleaning effect will be better. Alternatively, the transition surface 31 can be formed on the bottom surface of the container at the outlet side of the brushing area 4 in the direction of the flow of the cleaning liquid, so that the fruits and vegetables will need to climb at the outlet side of the brushing area 4, and thus the residence time of the fruits and vegetables in the brushing area 4 will be increased, and thus the cleaning effect will be enhanced. In addition, the wiping member 30 can be arranged on the transition surface 31, and the wiping member 30 is preferably arranged at a position downstream of the transition surface 31 in the direction of the flow of the cleaning liquid, i.e. the wiping member 30 is arranged at the highest point of the transition surface 31. At this position, the distance between the brushing area 12 and the wiping member 30 is the smallest or even crosses, and thus the fruits and vegetables will obtain more friction, and thus achieve better cleaning effect.

[0199] When the C-shaped brusher is used, since there is a space between the two adjacent rows of the first flexible cleaning objects 29, it is easy for the smaller fruits and vegetables to penetrate between the two adjacent rows of the first flexible cleaning objects 29, thus resulting in the following consequences: since the fruits and vegetables are located between the two adjacent rows of the first flexible cleaning objects 29, the fruits and vegetables are clamped between the two adjacent rows of the first flexible cleaning objects 29 when the brusher 2 rotates, and only rotate with the rotation of the brusher 2, and cannot break through the first flexible cleaning objects 29, so the fruits and vegetables cannot be brushed by the first flexible cleaning objects 29. Therefore, the brusher can further include a plurality of rows of second flexible cleaning objects 32, which are arranged between the two adjacent rows of the first flexible cleaning objects 29, and the height of the second flexible cleaning objects 32 is lower than the height of the first flexible cleaning objects 29, so that the smaller fruits and vegetables cannot penetrate too deeply between the two adjacent rows of the first flexible cleaning objects 29 (blocked by the second flexible cleaning objects 32), and can be brushed by the second flexible cleaning objects 32 and / or the first flexible cleaning objects 29 with different forces or contact sizes. The material, distribution and structure of the second flexible cleaning objects 32 can refer to the material, distribution and structure of the first flexible cleaning objects 29.

[0200] One or more rows of the second flexible cleaning objects 32 can be arranged between the two adjacent rows of the first flexible cleaning objects 29. If one row of the second flexible cleaning objects 32 is arranged between the two adjacent rows of the first flexible cleaning objects 29, it is recommended that the spacing between the two adjacent rows of the first flexible cleaning objects 29 and the spacing between the two adjacent rows of the second flexible cleaning objects 32 are equal in the radial cross section of the brusher 2, and the regular arrangement is conducive to enhancing the cleaning effect.

[0201] When the circulating driving mechanism circulates the cleaning liquid, the circulation of the cleaning liquid is mainly along the wall of the container 1, so there will be a dead water area (the cleaning liquid is basically stationary in this area) between the parallel arranged brusher 4 and the fruit and vegetable flow temporary storage area 3. Once the fruits and vegetables are in this dead water area, they cannot circulate with the circulating cleaning liquid, so they cannot be brushed by the brusher 2. In order to solve this problem, a barrier 10 can be arranged in the container 1, and the circulating channel surrounds the barrier 10, which can basically eliminate the dead water area, even if it cannot completely eliminate the dead water area, it can greatly reduce the range of the dead water area. It is recommended that the barrier 10 has an arc surface protruding towards the fruit and vegetable flow temporary storage area, which can not only further reduce the area of the dead water area, but also can push the flowing fruits and vegetables outward to prevent the fruits and vegetables from being stranded.

[0202] After the barrier 10 is set, one end of the rotating shaft 11 can be supported on the container 1, and the other end of the rotating shaft 11 is supported on or penetrates into the barrier 10. The installation of the rotating shaft 11 is not only simple, but also stable after installation. As mentioned above, the other end of the rotating shaft 11 and the barrier 10 are preferably detachably connected to facilitate dismounting of the brush washer 2.

[0203] The barrier 10 can be generally provided as a partition plate with a certain length to facilitate formation of the circulating channel. Of course, the barrier 10 can also be in the form of a blocking column.

[0204] The barrier 10 can be formed separately from the container 1 or integrally with the container 1. When the barrier 10 is formed separately from the container 1, the barrier 10 and the container 1 can be fixed by buckling, of course, they can also be fixed by screws, or a rail is formed on the container, and the barrier is inserted into the rail to be fixed. Figure 40 、 41 In the embodiment, a slide rail groove 33 is formed on the bottom surface of the barrier 10, and a slide rail 34 is formed on the bottom surface of the container 1. The slide rail 34 is slid into the slide rail groove 33 to achieve installation of the barrier 10. Figure 42 In the embodiment, a clamping protrusion 35 is formed on the lower part of the barrier, and an embedding groove is formed on the bottom surface of the container 1, and a clamping groove 36 is formed in the embedding groove. The clamping protrusion 35 is clamped into the clamping groove 36 to complete installation of the barrier 10. Figure 43 、 44 In the embodiment, the barrier 10 and the container 1 are connected by a screw rod. The screw rod penetrates into the barrier 10 from the container 1, and a penetrating rod 37 can be arranged in the barrier 10 for penetrating the screw rod. When the barrier 10 is integrally formed with the container 1, it is recommended that the barrier 10 is formed by forming a hollow protrusion on the bottom surface of the container 1. The forming is simple, and the protrusion forms the barrier 10.

[0205] As mentioned above, the barrier 10 can eliminate the dead water area to some extent, but cannot completely eliminate the influence of the dead water area, or the flow rate of the cleaning liquid near the barrier 10 is still slower than that of the cleaning liquid outside the container, and the fruits and vegetables near the barrier 10 still have the possibility of being retained near the barrier 10. Therefore, an inclined surface 38 can be arranged at the junction of the barrier 10 and the bottom surface of the container 1. The inclined surface 38 is inclined outward from top to bottom of the barrier 10, so that the fruits and vegetables at the junction of the barrier 10 and the container 1 flow outward along the inclined surface 38, and the fruits and vegetables at the junction of the barrier 10 and the container 1 re-enter the cleaning liquid with a faster flow rate.

[0206] After the barrier 10 is set, a fruit and vegetable inlet is formed between the downstream end of the barrier 10 and the side wall of the container 1 in the direction of the flow of the cleaning liquid. In order to prevent the fruit and vegetables from being congested at the fruit and vegetable inlet, a retracted guide surface is provided at the downstream end of the barrier 10 to form a wider fruit and vegetable guide opening between the guide surface and the side wall of the container.

[0207] Another measure to prevent the congestion of the fruit and vegetables is that the rotating shaft 11 is bidirectionally rotatable on the container, i.e. the rotating shaft 11 can rotate clockwise or counterclockwise. The simplest method to achieve this effect is to pass or mount the rotating shaft 11 on the container 1 without providing a one-way mechanism between the rotating shaft 11 and the container 1. After the rotating shaft 11 is designed to rotate bidirectionally, once the fruit and vegetables are congested in the container 1, the rotating shaft can be rotated in the opposite direction, so that the brusher 2 rotates in the opposite direction, and thus the cleaning liquid flows in the opposite direction, so as to disperse the congested fruit and vegetables, thereby solving the congestion of the fruit and vegetables.

[0208] When the brusher in the form of C is used, since the brusher 2 is arranged in the container with the rotating shaft 11 horizontally, the cleaning liquid in the container 1 will be splashed out when the brusher 2 rotates. Therefore, a splash-proof cover 39 can be provided on the brusher 2 to prevent the cleaning liquid from being splashed out. The splash-proof cover 39 most commonly includes a raised portion corresponding to the brusher 2 and a connecting portion connected to the container. Generally, the splash-proof cover 39 is a plastic part, and preferably a transparent plastic part, so that the cleaning condition in the brusher 4 can be observed. The splash-proof cover 39 can only cover the brusher 4, or can cover the area outside the brusher 4 as shown in the drawings, so as to close the open upper end of the container to achieve a better water-blocking effect. Figure 47

[0209] After the splash-proof cover 39 is provided, the water splashed out by the brusher 2 when rotating will be sprayed onto the splash-proof cover 39, and the water blocked by the splash-proof cover 39 will be back-flushed to the brusher 2, which will form resistance to the rotation of the brusher 2. In order to minimize the resistance, the minimum distance between the splash-proof cover 39 and the outer edge of the brusher 2 is 2 mm, so that the back-flushing pressure of the water blocked by the splash-proof cover 39 is controlled within a smaller range.

[0210] ​To further reduce the splashing of the cleaning liquid, a water blocking mechanism can be provided between the splash-proof cover 39 and the container 1 to block the water splashed by the brushing part 12 and prevent the water splashed by the brushing part 12 from leaking out of the container. The specific structure of the water blocking mechanism can be that the water blocking mechanism comprises a splash-proof groove 40 provided on the upper end surface of the container and a splash-proof rib 41 provided on the splash-proof cover, and the splash-proof rib 41 can be inserted into the splash-proof groove 40 when the splash-proof cover 39 covers the brushing area; or the water blocking mechanism comprises a splash-proof rib provided on the upper end surface of the container and a splash-proof groove provided on the splash-proof cover, and the splash-proof rib can be inserted into the splash-proof groove when the splash-proof cover covers the brushing area. The splash-proof rib can block the cleaning liquid, and the splash-proof groove can accommodate the blocked cleaning liquid.

[0211] Another specific structure of the water blocking mechanism can be that the water blocking mechanism comprises a sealing ring 42 provided between the splash-proof cover 39 and the container 1, and the sealing ring 42 achieves water sealing to basically prevent the splashing of the cleaning liquid.

[0212] Generally, the splash-proof cover 39 is detachably connected with the container 1, and after the splash-proof cover 39 is removed, the brushing area 4 is convenient to clean, replace the brush, etc. The splash-proof cover 39 usually only needs to be placed on the container 1, and of course, buckle connection, screw connection, etc. can be used for detachable connection between the splash-proof cover 39 and the container 1 for further stability.

[0213] After the splash-proof cover 39 is provided, the aforementioned "blocking part 10" can also be provided on the splash-proof cover 39, that is, a partition is provided on the splash-proof cover 39, and when the splash-proof cover 39 covers the brushing area, the partition can extend into the container 1, so that the circulation channel surrounds the partition.

[0214] As a preferred structure, a water filtering opening 43 can be provided on the side wall of the container 1, and the height of the cleaning liquid in the container 1 does not exceed the position of the water filtering opening. After the fruits and vegetables are cleaned, the cleaning liquid can be poured out through the water filtering opening 43, and the fruits and vegetables are retained in the container 1 and cannot be poured out from the water filtering opening.

[0215] As a preferred structure, a draining basket 44 is provided in the container 1, and the fruits and vegetables are placed in the draining basket 44 during cleaning, and after cleaning, the draining basket 44 is lifted out. The bottom surface of the draining basket 44 is preferably substantially attached to the bottom surface of the container 1 to avoid the loss of space in the container 1. The so-called "substantial attachment" means that the bottom surface of the draining basket 44 can be completely attached to the bottom surface of the container 1, or there is a small gap between them. In order to facilitate the removal of the draining basket 44, a gap is provided on the draining basket 44, and the brush 2 is located in the gap, so that the fruits and vegetables in the container 1 can be basically lifted out.
