[0002] A fruit and vegetable purifier is a household appliance used to clean pesticide residues, bacteria, dust, and other contaminants from the surface of fruits and vegetables. Currently, most fruit and vegetable purifiers on the market feature an agitating impeller; the rotation of the impeller agitates the water flow to improve purification efficiency.
[0003] The impeller is usually not detachable, which makes cleaning difficult. Later, air purifiers with end caps to limit and fix the impeller were introduced to the market. Although the impeller can be detached for cleaning, the impeller is in contact with the end cap during use, which generates a lot of noise during rotation, resulting in a poor user experience.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0034] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments: Example
[0035] like Figures 1 to 5 As shown in the figure, this utility model embodiment discloses a fruit and vegetable purifier, including a purification body 1, an agitator impeller 2, a purification component 3, and an end cover 4. The purification component 3 is provided with a sealed chamber and a fixed shaft 12. At least a drive component (not shown in the figure) and a control component (not shown in the figure) are installed in the sealed chamber 11. The fixed shaft 12 is provided with a limiting part 121 in the circumferential direction. The agitator impeller 2 is arranged around the fixed shaft 12 and is connected to the drive component. The inner edge of the agitator impeller 2 is provided with a positioning part 201 in the circumferential direction that is adapted to the concave and convex shape of the limiting part. The positioning part 201 is located below the limiting part 121. When the agitator impeller 2 rotates, the positioning part 201 and the limiting part 121 are misaligned to prevent the agitator impeller 2 from detaching from the purification body 1. When the agitator impeller 2 is disassembled and assembled, the positioning part 201 is connected to the limiting part 121.
[0036] An agitator impeller 2 is arranged around a fixed shaft 12 of the purification body 1. A limiting part 121 is added to the fixed shaft 12, and a positioning part 201 is added to the inner edge of the agitator impeller 2. The contours of the positioning part 201 and the limiting part 121 are adapted to each other, so that when the positioning part 201 and the limiting part 121 are connected, the agitator impeller 2 can be installed by sliding it from the top of the fixed shaft 12 downwards onto the outer periphery of the fixed shaft 12, and the agitator impeller 2 can also be disassembled by moving it upwards from the bottom of the fixed shaft 12. At the same time, the agitator impeller 2 is fixed to the purification body 1. After the shaft 12 is assembled and installed, the positioning part 201 is located below the limiting part 121, and the positioning part 201 and the limiting part 121 are misaligned. During the rotation of the agitator impeller 2, the limiting part 121 cannot be connected with the positioning part 201, ensuring that the agitator impeller 2 does not detach from the fixed shaft 12 and the purification body 1. The friction between the agitator impeller and the fixed shaft is reduced, which improves the rotation efficiency of the drive component and greatly reduces noise. This solves the problem of high noise in the existing method of using the end cover 4 to abut against the agitator impeller 2, and greatly improves the user experience.
[0037] At least one limiting part 121 and a positioning part 201 are provided. Generally, the number of limiting parts 121 is the same as the number of positioning parts 201. Preferably, there are two, three, or four limiting parts 121 and positioning parts 201. The specific number can be adjusted according to actual needs. The limiting parts 121 can be evenly distributed in a ring, and the positioning parts 201 can be correspondingly evenly distributed in a ring.
[0038] The diameter of the limiting part 121 is consistent along the axial direction of the fixed shaft 12, and the diameter of the positioning part 201 is consistent along the axial direction of the agitator impeller 2.
[0039] It also includes an end cover 4 and a purification component 3. The end cover 4 is detachably installed on the top of the fixed shaft 12. A purification chamber is formed between the end cover 4 and the top of the fixed shaft 12. The purification component 3 is installed in the purification chamber. The end cover 4 is provided with a through hole that connects to the purification chamber.
[0040] The purification component 3 can be a purification component 3 in the prior art, including an electrolysis device, an ultrasonic purification device, an ozone device, etc. for cleaning fruits and vegetables.
[0041] Furthermore, the fixed shaft 12 is provided with a circumferential groove 122 and an opening 123, the opening 123 is connected to the groove 122, and the end cover 4 is provided with a fixing buckle 41, which enters through the opening 123 and rotates to assemble with the groove 122.
[0042] The end cover 4 and the fixed shaft 12 can be detachably installed by means of threaded installation, screw installation, snap-fit installation, etc.
[0043] Furthermore, the drive assembly includes a drive component, an output shaft, and a transmission gear. A rack 21 is circumferentially mounted on the outer periphery of the agitator impeller 2. The drive component drives the output shaft to rotate. One end of the output shaft extends out of the sealed chamber 11 and is fitted with a transmission gear, which meshes with the rack 21. The drive component is typically an electric motor.
[0044] The control components also include power modules, controllers, and other structures, which are existing technologies and will not be described in detail here.
[0045] In some implementations, such as Figure 1 and Figure 2 As shown, a limiting part 121 is formed by a radial protrusion on the outer wall of the fixed shaft 12, and a positioning part 201 that fits the limiting part 121 is formed by a vertically extending inner ring edge of the agitator impeller 2.
[0046] The shape of the limiting part 121 can be semi-cylindrical, rectangular, strip-shaped, tooth-shaped, etc., and the concave contour of the positioning part 201 is adapted to the limiting part 121.
[0047] The limiting part 121 protrudes slightly from the outer periphery of the fixed shaft 12. The limiting part 121 has a small overall volume, a small extension width along the axial direction of the fixed shaft 12, and a small extension thickness along the radial direction of the fixed shaft 12. This ensures that after the positioning part 201 is aligned with the limiting part 121, the agitator 2 can slide into the fixed shaft 12 from the top end to complete the installation of the agitator 2 and the purification body 1, or slide out from the bottom end of the fixed shaft 12 to complete the separation of the agitator 2 and the purification body 1. At the same time, it ensures that after the positioning part 201 and the limiting part 121 are misaligned, the agitator 2 will not detach from the fixed shaft 12 during the rotation of the agitator 2 under the drive of the drive assembly.
[0048] Furthermore, the limiting part 121 has a first contact surface at one end facing the stirring impeller 2, and the stirring impeller 2 has a second contact surface on one side facing the limiting part 121, with the first contact surface and the second contact surface being separate.
[0049] The limiting part 121 has a certain distance between one end with the first contact surface and the side of the stirring impeller 2 with the second contact surface, so as to ensure that the stirring impeller 2 rotates smoothly under the drive of the drive component, stirring the water flow and improving the purification efficiency.
[0050] Furthermore, there is a certain distance between the lower edge of the end cover 4 and the other end of the limiting part 121.
[0051] The protruding limiting part 121 and the purification body 1 form an annular limiting track for the agitator impeller 2 to rotate. The agitator impeller 2 does not detach from the purification body 1 during rotation. The protruding limiting part 121 and the recessed positioning part 201 cooperate with each other to enable the agitator impeller 2 to be disassembled and installed from the purification body 1, making it convenient for users to clean the parts.
[0052] In some embodiments, the outer wall edge of the fixed shaft 12 extends vertically to form a limiting part, and the inner ring edge of the agitator impeller 2 protrudes towards the center to form a positioning part that matches the limiting part. The fixed shaft 12 has a shape that is larger at the top and smaller at the bottom.
[0053] Similarly, the shape of the positioning part can be semi-cylindrical, rectangular, strip-shaped, toothed, etc., and the concave contour of the limiting part is adapted to the positioning part.
[0054] The positioning part protrudes slightly from the inner edge of the agitator impeller 2. The positioning part has a small overall volume, a small extension width along the axial direction of the agitator impeller 2, and a small extension thickness along the radial direction of the agitator impeller 2. This ensures that after the positioning part and the limiting part are aligned, the agitator impeller 2 can slide into the fixed shaft 12 from the top to complete the installation of the agitator impeller 2 and the purification body 1, or slide out from the lower end of the fixed shaft 12 to complete the separation of the agitator impeller 2 and the purification body 1. At the same time, it ensures that after the positioning part and the limiting part are misaligned, the agitator impeller 2 will not detach from the fixed shaft 12 during rotation under the drive of the drive component.
[0055] Furthermore, after the agitator impeller 2 and the purification body 1 are assembled, a certain distance is left between the protruding positioning part on the agitator impeller 2 and the recessed limiting part on the fixed shaft 12 to ensure that the agitator impeller 2 rotates smoothly.
[0056] Furthermore, the fixed shaft 12 is provided with an annular track facing the bottom side of the inner ring of the agitator impeller 2, and the top of the positioning part is rotatably fitted into the annular track.
[0057] The protruding positioning part on the agitator impeller 2 extends upward to a certain height and is rotatably fitted into the annular track set on the bottom side of the fixed shaft 12, thereby improving the smoothness of the rotation of the agitator impeller 2.
[0058] The recessed limiting part and the raised positioning part can realize the disassembly and installation of the stirring impeller 2 and the purification body 1, which is convenient for users to clean. The fixed shaft 12 with a stepped structure with a larger upper part and a smaller lower part forms a limiting track for the rotation of the stirring impeller 2 with the purification body 1, so that the stirring impeller 2 does not detach from the purification body 1 during the rotation process.
[0059] In some embodiments, the outer diameter of the end cover 4 is larger than the inner diameter of the stirring gear. The end cover 4 can serve as a last line of defense for the safe use of the stirring impeller 2, preventing the stirring impeller 2 from flying out and causing injury.
[0060] Multiple blades 202 are provided on the inner side of the agitator impeller 2. They can be evenly arranged. The blades 202 are arranged radially or in a spiral direction. When the agitator impeller 2 rotates, the blades 202 push the water flow. Example
[0061] like Figures 1 to 5 As shown in the figure, this utility model embodiment also provides a fruit and vegetable purifier, including a purification body 1, an agitator impeller 2, an end cover 4, and a purification component 3. The purification body 1 is provided with a sealed chamber and a fixed shaft 12. At least a drive component and a control component are installed in the sealed chamber 11. A limiting part 121 is detachably installed on the fixed shaft 12 in the circumferential direction. The limiting part 121 protrudes from the outer periphery of the fixed shaft 12. The agitator impeller 2 is arranged around the fixed shaft 12. The agitator impeller 2 is connected to the drive component. The limiting part 121 restricts the agitator impeller 2 from detaching from the purification body 1. The end cover 4 is detachably installed on the top of the fixed shaft 12. The end cover 4 and the top of the fixed shaft 12 form a purification chamber. The purification component 3 is disposed in the purification chamber.
[0062] The shape and size of the limiting part 121 can refer to the limiting part 121 that is protruding on the fixed shaft 12 in Embodiment 1. The purification component 3, the drive component and the agitator impeller 2 also refer to Embodiment 1, but the agitator impeller 2 does not need to be provided with the positioning part 201.
[0063] The limiting part 121 is detachable. After the agitator impeller 2 is sleeved on the fixed shaft 12, the limiting part 121 is installed. There is a certain distance between the limiting part 121 and the agitator impeller 2 to ensure that the agitator impeller 2 rotates more smoothly. When disassembling the agitator impeller 2, the limiting part 121 is removed first, and then the agitator impeller 2 is moved out from bottom to top, which is convenient and efficient.
[0064] The limiting part 121 can be set in two, three, four, etc. The number of limiting parts 121 can be adjusted according to actual needs, and the lower edge of the limiting part 121 is kept on the same horizontal plane.
[0065] In some embodiments, the limiting part 121 and the fixed shaft 12 can be connected by threads. Specifically, a threaded hole is opened on the outer periphery of the fixed shaft 12, and the limiting part 121 has a corresponding threaded post. The threaded post of the limiting part 121 is screwed into the threaded hole to complete the installation.
[0066] In some embodiments, the limiting part 121 and the fixed shaft 12 can be installed in a sliding groove. Specifically, the fixed shaft 12 is provided with a sliding groove, which has an inlet section from top to bottom and a fixed groove section along the circumferential direction of the fixed shaft 12. The width of the sliding groove increases from the outside to the inside. Correspondingly, the limiting part 121 is provided with a sliding member that is adapted to the sliding groove.
[0067] For example, the width of the groove is shaped like an inverted U-shape from the outside in, and the sliding part is shaped like a U-shape.
[0068] The assembly of the limiting part 121 and the fixed shaft 12 is completed by sliding the sliding member into the groove section and then into the fixed groove section. The circumferential path of the sliding member into the groove is consistent with the rotation direction of the agitator impeller 2. That is, the direction from the entry end to the end of the fixed groove section is consistent with the rotation direction of the agitator impeller 2, ensuring that the limiting part 121 will not move along the groove during the rotation of the agitator impeller 2.
[0069] For example, the fixed shaft 12 has C-shaped, L-shaped, arc-shaped grooves and other sliding grooves.
[0070] The main functions of this utility model are:
[0071] By designing a limiting part and a positioning part, the positioning part and the limiting part are connected to achieve the disassembly and cleaning of the agitator impeller. During use, the positioning part and the limiting part are misaligned to prevent the agitator impeller from detaching from the fixed shaft. At the same time, the friction between the agitator impeller and the fixed shaft is reduced, which improves the motor rotation efficiency and greatly reduces the noise during rotation. This solves the problem of high noise in the current limiting method of using an end cover to agitate the impeller, and improves the user experience.
[0072] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
