Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a fruit and vegetable purifier. Background Technology

[0002] For fruits and vegetables that are difficult to clean and come in large quantities, cleaning them thoroughly is undoubtedly time-consuming and laborious. In particular, some fruits and vegetables cannot be completely cleaned by simply rinsing and scrubbing with water. Starch is needed to absorb the dust, dirt, pesticides, etc. that are stuck to the fruits and vegetables. Directly pouring away the starch water after washing the fruits and vegetables can easily cause sewer blockage.

[0003] Currently, most fruit and vegetable washing machines on the market use water hydroxyl technology and / or mechanical swirling water flow technology. The latter uses swirling water flow to rub against the surface of fruits and vegetables, thus removing dirt from their skin.

[0004] The cleaning effect of water flow on fruits and vegetables depends on the force of the water flow rubbing against the surface of the fruits and vegetables. If the water flow rotates axially in one direction, the fruits and vegetables will be stirred and rotated together. In this case, the friction between the water flow and the fruits and vegetables is very small, and the cleaning effect is poor. When the water flow is swirling in a boiling and rolling manner, the friction between the water flow and the fruits and vegetables is greater, and the cleaning effect is better. However, for some stubborn stains, such as dirt on the surface of the fruits and vegetables, it is difficult to completely clean them in a short time by hand scrubbing.

[0005] Some fruit and vegetable washing machines are equipped with water tanks with bristles on the inner surface. The washing machine rotates the water flow axially, and the fruits and vegetables are carried by the water flow to rotate along the water tank and be rubbed and cleaned by the bristles. However, because the water flow direction is unidirectional, it is difficult for the fruits and vegetables to change the brushing surface in contact with the bristles, resulting in a low brushing coverage. In addition, the water tank limits the space provided for washing fruits and vegetables, making it difficult to adapt to fruits and vegetables of various shapes and quantities. It also increases the difficulty for users to clean and maintain the fruit and vegetable washing machine, occupies a large storage space, and greatly affects users' enthusiasm for using fruit and vegetable washing machines to clean fruits and vegetables. Utility Model Content

The fruit and vegetable purifier is equipped with a scrubbing area, and the fruit and vegetable purifier can drive the fruits and vegetables into the scrubbing area in different postures by rotating the water flow for multi-angle scrubbing and cleaning, thereby increasing the cleaning efficiency and cleaning coverage of the fruit and vegetable skin.

[0007] Another advantage of this utility model is that it provides a fruit and vegetable purifier, wherein the fruit and vegetable purifier can push the nearby water flow outward, so that the washing area forms a low pressure, and the outer water flow carries the fruits and vegetables into the washing area one after another for washing, and then leaves the washing area. In this way, the fruits and vegetables continuously enter and exit the washing area under the complex flow field to be washed in turn.

[0008] Another advantage of this invention is that it provides a fruit and vegetable purifier, wherein the fruit and vegetable purifier can drive the fruit and vegetables to rotate to change the brushing surface of the fruit and vegetables facing the brush body, thereby increasing the brushing coverage of the fruit and vegetables.

[0009] Another advantage of this invention is that it provides a fruit and vegetable purifier that can remain stable in water during the process of swirling water flow.

[0010] Another advantage of this utility model is that it provides a fruit and vegetable purifier, wherein the fruit and vegetable purifier is equipped with a brush cover. When the fruit and vegetable purifier rotates the water flow, it can drive the brush cover to rotate. The rotation of the brush cover further enhances the water flow rotation in the brushing area and forms multiple vortices, driving the fruits and vegetables into the brushing area and colliding with multiple brushes on the brush cover, thereby cleaning the surface of the fruits and vegetables through the friction of the brushes.

[0011] Another advantage of this invention is that it provides a fruit and vegetable purifier, wherein the shape of the brush body assembly on the brushing cover corresponds to the water flow swirling in the brushing area, so that when fruits and vegetables enter the brushing area, the brush body can brush the surface of the fruits and vegetables in multiple directions, which helps to clean the dents and crevices on the surface of the fruits and vegetables.

[0012] Another advantage of this invention is that it provides a fruit and vegetable purifier, wherein the fruit and vegetable purifier has a hydroxyl generator capable of electrolyzing water to generate hydroxyl free radicals. The position of the hydroxyl generator is designed to facilitate the generation and diffusion of hydroxyl free radicals, and to facilitate the direct entry of the high-concentration hydroxyl free radicals generated by the hydroxyl generator into the scrubbing area to react with the surface of the fruit and vegetables.

[0013] Another advantage of this invention is that it provides a fruit and vegetable purifier, which can be placed in water tanks of different models and shapes to clean and purify fruits and vegetables of various quantities, shapes and sizes.

[0014] Another advantage of this utility model is that it provides a fruit and vegetable purifier, wherein the scrubbing cover is detachably installed in the fruit and vegetable purifier, so that users can disassemble and wash or replace the scrubbing cover as needed, and can also select the shape and material of the scrubbing cover according to the cleaning needs of fruits and vegetables.

[0015] Another advantage of this invention is that it provides a fruit and vegetable purifier that is self-cleaning and easy to disassemble for deep cleaning. This avoids users having doubts about the cleanliness of the internal structure of the purifier, which is exposed to dirt, and increases users' enthusiasm for using the purifier to clean fruits and vegetables.

[0016] Another advantage of this utility model is that it provides a fruit and vegetable purifier, which is easy to install, so that users can correctly install it after disassembling it, thus avoiding the frequent installation and disassembly of the fruit and vegetable purifier from affecting its service life.

[0053] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0054] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0055] like Figure 1As shown, the fruit and vegetable purifier 100 according to the first preferred embodiment of the present invention is used to place in a container filled with water to clean fruits and vegetables. The fruit and vegetable purifier 100 includes a main body 10, a rotating impeller 20 and a brush cover 30. The rotating impeller 20 includes an inner hub 21 and a plurality of blades 22 connected to the inner hub 21. The blades 22 are configured to generate upward and radial thrust on the water based on rotation when the rotating impeller 20 is placed in the water in a horizontal state. The rotating impeller 20 surrounds the brush cover 30, and the top of the brush cover 30 is provided with a plurality of brush bodies 31.

[0056] It is understood that the main body 10 is used for the assembly of corresponding circuits and drive modules, such as circuit boards, motors, etc., and its shape and features are diverse, which are not limited in this utility model.

[0057] The fruit and vegetable purifier 100 also includes a hydroxyl generator 40, with the rotating impeller 20 arranged in a ring around the hydroxyl generator 40 and the brush cover 30 located above the hydroxyl generator 40. The hydroxyl generator 40 electrolyzes and generates hydroxyl free radicals that diffuse outward through the brush cover 30.

[0058] like Figure 2 and Figure 3 As shown, the brush body 31 in the brush cover 30 has an overall dome-shaped profile with a high center and low outer edge, so as to guide the fruits and vegetables piled in the central area to the surrounding area for brushing. The brush body 31 is arranged to form multiple brush clusters 310 that spiral outward from the central area. Each brush cluster 310 gradually narrows from the proximal end near the center to its distal end.

[0059] A cavity 32 is formed at the near-end center of any of the brush clusters 310, thereby reducing the impact force of the near end of the brush cluster 310 on the water flow, providing support for fruits and vegetables and performing preliminary washing.

[0060] Furthermore, a guide channel 33 is formed between two adjacent brush clusters 310, which spiral outward from the center. Fruits and vegetables located near the brush cluster 310 move to the far end of the brush cluster 310 through the guide channel 33, so that the brush cluster 310 can brush the fruits and vegetables from multiple angles, which helps to clean the depressions and crevices on the surface of the fruits and vegetables. The far ends of the multiple brush clusters 310 are provided with multiple brush bodies 31 arranged in a ring array to serve as the boundary of the guide channel 33, increasing the brushing density and brushing angle of the fruits and vegetables.

[0061] The guide channel 33 is provided with multiple openings 34, which are connected to the hydroxyl generator 40. The hydroxyl free radicals generated by the electrolysis of the hydroxyl generator 40 diffuse outward through the openings 34. In this way, the fruits and vegetables located in the scrubbing area 301 formed by the brush body 31 can directly react with the high concentration of hydroxyl free radicals, thereby increasing the reaction rate of hydroxyl free radicals with toxic and harmful substances on the surface of fruits and vegetables, and thus increasing the cleaning speed of the fruit and vegetable purifier 100.

[0062] like Figure 4 and Figure 5 As shown, the fruit and vegetable purifier also includes an inner rotating body 50 and a drive gear 60. The rotating impeller 20 is coaxially arranged around the inner rotating body 50. The rotating impeller 20 and the inner rotating body 50 are driven by the drive gear 60 to rotate in opposite directions.

[0063] The inner rotating body 50 has a plurality of inner rotating blades 51 arranged radially, and each inner rotating blade 51 is configured to generate a radial thrust on the water based on rotation when the inner rotating body 50 is placed in water in a horizontal state.

[0064] The rotating impeller 20 rotates in the forward direction to push the water flow to swirl in the upward and radial directions, while the inner swirling body 50 rotates in the reverse direction to push the water flow to swirl in the opposite direction. The water flow swirling in the inner swirling body 50 collides and merges with the water flow swirling in the rotating impeller 20, thereby forming a continuously boiling, tumbling and spreading water flow, which accelerates the diffusion of hydroxyl radicals generated by the hydroxyl generator 40.

[0065] The inner rotating body 50 surrounds and fixes the brush cover 30. The inner rotating body 50 drives the brush cover 30 to rotate. The brush body 31 of the brush cover 30 further pushes the nearby water flow to rotate in the same direction as the inner rotating blades 51 rotate. The rotating brush body 31 causes multiple vortices to be generated in the brushing area 301. Fruits and vegetables entering the brushing area 301 are drawn into these vortices and come into contact with the brush body 31, increasing the contact time between the fruits and vegetables and the brush body 31, and improving the brushing frequency and brushing coverage of the brush cover 30.

[0066] Specifically, such as Figure 4 As shown, the inner rotating body 50 includes a bayonet 52 located on each of the inner rotating blades 51. The bayonet 52 of the multiple inner rotating blades 51 form a ring array of multiple bayonet 52. The brush cover 30 is fixed to the inner rotating body 50 by engaging with the multiple bayonet 52.

[0067] The inner rotating body 50 also includes a support frame 53 located at the top of the inner rotating body 50 and extending from its edge toward the center. The top of the brush cover 30 can abut against the support frame 53, so that the support frame 53 provides support for the brush cover 30. The support frame 53 is provided with at least one positioning hole 54, and the brush cover 30 is provided with at least one positioning pin 35. The brush cover 30 is fixed to the inner rotating body 50 by the insertion and engagement of the positioning pin 35 with the positioning hole 54.

[0068] like Figure 5 As shown, the rotating impeller 20 also includes a drive ring 23. The inner hub 21 is fixed to the drive ring 23. The drive ring 23 drives each blade 22 to rotate through the inner hub 21. The inner hub 21 is provided with a plurality of fixing pins 211. The upper part of the drive ring 23 is provided with a plurality of fixing holes 231. The plurality of fixing pins 211 are inserted into the plurality of fixing holes 231 to fix the inner hub 21 to the upper part of the drive ring 23.

[0069] The drive ring component 23 also includes a plurality of guide grooves 232 corresponding to each of the fixing holes 231. Each of the plurality of guide grooves 232 forms a notch on the top of the drive ring component 23 to guide the fixing hole 231. The user aligns the plurality of fixing pins 211 on the inner hub 21 one by one with the plurality of guide grooves 232 of the drive ring component 23, and then pushes the inner hub 21 to press the plurality of fixing pins 211 into the plurality of fixing holes 231 for insertion and engagement, thereby assembling and installing the inner hub 21 and the drive ring component 23 together.

[0070] like Figure 5 and Figure 6 As shown, the upper end of the main body 10 is provided with an outer ring wall 11 and a plurality of elastic limiting members 12 located on the outer ring wall 11. The outer ring surface of the driving ring member 23 is provided with a limiting ring groove 233. Each of the elastic limiting members 12 is engaged with the limiting ring groove 233. When the driving ring member 23 rotates, the elastic limiting members 12 restrict the driving ring member 23 from disengaging from the main body 10, and do not hinder the rotation of the driving ring member 23.

[0071] The main body 10 also includes an inner ring wall 13, the inner rotating body 50 is sleeved on the inner ring wall 13, and an installation chamber 14 is formed between the outer ring wall 11 and the inner ring wall 13. The driving ring 23 and the inner rotating body 50 are located in the installation chamber 14.

[0072] The outer ring surface of the inner rotating body 50 is provided with an outwardly protruding first limiting part 55, and a rotating chamber 56 is defined above the first limiting part 55. Each of the inner rotating blades 51 is located in the rotating chamber 56. The inner ring surface of the driving ring member 23 is provided with an outwardly protruding second limiting part 234. The outwardly protruding end of the second limiting part 234 extends into the rotating chamber 56. When the inner rotating body 50 moves outward away from the main body 10, the first limiting part 55 abuts against the second limiting part 234 to prevent the inner rotating body 50 from continuing to move outward, thereby limiting the inner rotating body 50.

[0073] The inner ring wall 13 surrounds and forms the generating chamber 15, and the hydroxyl generator 40 is located in the generating chamber 15.

[0074] The bottom of the main body 10 is also provided with a suction cup 16, which further stabilizes the position of the fruit and vegetable purifier 100 in the water through the adsorption force of the suction cup 16.

[0075] like Figure 5 and Figure 7 As shown, the drive gear 60 protrudes outward from the mounting chamber 14, the inner rotating body 50 is provided with an external toothed ring 57 below the first limiting part 55, the drive ring 23 is provided with an internal toothed ring 235 below the second limiting part 234, the drive gear 60 is located between the internal toothed ring 235 and the external toothed ring 57 and drives the rotating impeller 20 and the inner rotating body 50 to rotate in opposite directions through meshing transmission.

[0076] The rotating impeller 20 is provided with an outer wall 24 that connects the outer ends of each blade 22 to form a continuous annular shape, so as to avoid the blades 22 impacting and damaging fruits and vegetables during rotation.

[0077] When the fruit and vegetable purifier 100 cleans fruits and vegetables, the drive gear 60 meshes with the inner vortex body 50 and the rotating impeller 20 to rotate in opposite directions. During the forward rotation, the rotating impeller 20 continuously stirs the nearby water flow upward and radially, while the inner vortex body 50 continuously stirs the nearby water flow in the reverse rotation. The water flows in different directions collide to form multiple eddies, and the fruits and vegetables are drawn into the eddies and tumble irregularly. The water flow continuously impacts and rubs the surface of the fruits and vegetables to carry away the impurities adhering to the surface. Due to the influence of weight, shape, volume, etc., these impurities and fruits and vegetables have different movement trajectories in the tumbling and spreading water, and will gradually be carried away from the fruits and vegetables by the water flow, completing the initial cleaning of the fruits and vegetables.

[0078] The fruit and vegetable purifier 100 is subjected to the reaction force generated by the water flow during the swirling process, thereby maintaining its stability in a complex flow field.

[0079] like Figure 2 and Figure 3 As shown, as the fruit and vegetable purifier 100 continuously rotates the water flow, part of the water flow diffuses outward, while another part carries the fruits and vegetables towards the central area and enters the scrubbing zone 301 to fill the backflow. The scrubbing cover 30 rotates in the same direction as the inner rotating body 50. The brush body 31 on the scrubbing cover 30 rotates the water flow and generates multiple eddies. The fruits and vegetables are drawn into these eddies and collide with the brush body 31. The fruits and vegetables in the central area move outward along the guide channel 33. During this time, the brush body 31 scrubs the fruits and vegetables from multiple angles. The hydroxyl radicals generated by the electrolysis of the hydroxyl generator 40 diffuse through the opening 34 and react directly with the fruits and vegetables, thereby deeply cleaning them. The water flow continues to move the fruits and vegetables outward and tumble irregularly. In this way, the water flow continuously carries the fruits and vegetables in and out of the scrubbing zone 301 for cleaning, greatly increasing the cleaning power and efficiency of the fruits and vegetables.

[0080] The brush body 31 can be made of silicone, which is soft and easy to clean.

[0081] like Figure 5 As shown, the fruit and vegetable purifier 100 can perform daily cleaning by rotating water flow. In addition, the fruit and vegetable purifier 100 can be disassembled for deep cleaning. Specifically, the inner hub 21 and drive ring 23 of the rotating impeller 20, as well as the inner rotating body 50 and the brush cover 30 of the fruit and vegetable purifier 100 are disassembled from the main body 10 in sequence and brushed and cleaned one by one. After thoroughly cleaning each component of the fruit and vegetable purifier 100, the inner rotating body 50 is fitted onto the inner ring wall 13 of the main body 10. Then, the drive ring 23 is pressed against the elastic limiting member 12 so that the elastic limiting member 12 is engaged with the limiting ring groove 233. Finally, the fixing pin 211 on the inner hub 21 is aligned with the guide groove 232 of the drive ring 23, and the inner hub 21 is pressed to insert the fixing pin 211 into the fixing hole 231, thereby completing the assembly of the fruit and vegetable purifier 100.

[0082] like Figures 8 to 10As shown, a fruit and vegetable purifier 100' according to a second preferred embodiment of the present invention is illustrated. The fruit and vegetable purifier 100' has a brush cover 30' with a plurality of brush bodies 31' on top. The brush bodies 31' in the brush cover 30' have an overall dome-shaped profile with a high center and low outer edge, so as to guide the fruits and vegetables piled in the central area to the surrounding area for brushing. The brush bodies 31' are arranged to form a plurality of brush clusters 310' that radiate outward from the central area. Each brush cluster 310' gradually thickens from the proximal end near the center to its distal end. The inner rotating blades 51 of the inner rotating body 50 surround the brush cover 30' and drive the brush cover 30' to rotate in the same direction. During the forward rotation, the brush clusters 310' further enhance the water flow swirling in the central area and form a plurality of vortices. The fruits and vegetables that are drawn into the vortices come into contact with the brush bodies 31' for cleaning.

[0083] Between two adjacent brush clusters 310', a guide channel 33' is formed, which is also radially surrounding the center area. Fruits and vegetables located near the brush cluster 310' move to the far end of the brush cluster 310' through the guide channel 33'. The far ends of multiple brush clusters 310' are provided with multiple brush bodies 31' in a ring array to serve as the boundary of the guide channel 33', so that the brush clusters 310' can brush fruits and vegetables from multiple angles, which helps to clean the dents and crevices on the surface of fruits and vegetables.

[0084] The guide channel 33' is provided with multiple openings 34', which are connected to the hydroxyl generator 40. The hydroxyl radicals generated by the electrolysis of the hydroxyl generator 40 diffuse outward through the openings 34' to react with the fruits and vegetables located in the scrubbing zone 301' formed by the brush body 31'.

[0085] like Figure 11 As shown, a fruit and vegetable purifier 100 according to a third preferred embodiment of the present invention is illustrated. The fruit and vegetable purifier 100 includes a plurality of brushes 31 disposed on the rotating impeller 20, the brushes 31 extending radially from the outer wall 24 of the rotating impeller 20.

[0086] As the rotating impeller 20 rotates, the water flow near it flows upward and radially. The brush body 31 on the outer wall 24 rotates accordingly. When the fruits and vegetables are carried by the water flow from bottom to top through the outer wall 24, they collide with the brush body 31 on the outer wall 24. The brush body 31 rotates and rubs against the fruits and vegetables, pushing them away from the outer wall 24. The fruits and vegetables are then carried by the outer water flow downward and axially towards the main body 10, thereby increasing the frequency of fruit and vegetable washing and accelerating the cleaning efficiency.

[0087] like Figure 12As shown, a fruit and vegetable purifier 100 according to a fourth preferred embodiment of the present invention is illustrated. The main body 10 of the fruit and vegetable purifier 100 is provided with a plurality of outwardly extending brushes 31. Each brush 31 on the main body 10 is located below the rotating impeller 20. During the upward and radial flow of water near the rotating impeller 20, a low pressure is formed in the area below the rotating impeller 20. The outer water flow carries fruits and vegetables to fill the gap in the area below. The fruits and vegetables are driven to impact the main body 10 to collide and rub against the brushes 31 on the main body 10 for washing, and then move upward with the water flow spun by the rotating impeller 20.
