Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, specifically, it relates to a multi-functional cleaning device. Background Technology

[0002] As living standards improve, people's demands for automated cleaning are gradually increasing. Taking baby bottles as an example, baby bottles generally include the bottle body, nipple, dust cover and screw cap. As baby products, baby bottles are frequently cleaned, have high cleaning requirements, and the cleaning task is heavy.

[0003] Besides baby bottles, there are various other items that need to be cleaned in daily life, such as straws, bottle caps, and water cups. Existing cleaning equipment generally cleans these items by rotating and spraying them with a spray arm. However, the spray arm cannot be replaced, resulting in a limited cleaning method. For items with narrow nozzles, it cannot thoroughly clean the inner cavity of the nozzle and requires secondary manual cleaning, so the cleaning effect needs to be improved.

[0004] In addition, the cleaning capacity is generally fixed, and its adaptability to parts of different heights is low. During cleaning, because the bottle body is relatively tall and the nipple, dust cover and screw cap are relatively short, the various parts of the bottle are placed haphazardly on the bottle rack or dish rack, which will create blind spots in cleaning and result in incomplete cleaning. Summary of the Invention

Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0067] refer to Figure 1 , Figure 2 This application proposes a cleaning device, which includes a housing 100, a base 110, a shelf assembly 200, and a spray assembly 300.

[0068] The outer shell 100 is a shell structure with a washing cavity inside. A cover is provided on the outer shell 100 to seal the washing cavity.

[0069] The base 110 is located at the bottom of the outer casing 100, providing a supporting foundation for the entire cleaning equipment.

[0070] The base 110 has an inner cavity for installation, and a water supply component is installed in the inner cavity.

[0071] The water supply assembly is mainly used to supply water to the washing chamber. It includes a water supply pump. In addition to the water supply assembly, a drainage assembly is also installed in the washing chamber to drain the water from the washing chamber.

[0072] The cleaning equipment also includes a water tank 120, specifically a clean water tank 120, which is used to connect to the water supply component. Of course, the cleaning equipment can also be equipped with a wastewater tank 120, which is used to connect to the drainage component to temporarily store wastewater. Alternatively, the drainage component of the cleaning equipment involved in this application can be connected to an external drainage pipe assembly to directly discharge wastewater.

[0073] The shelf assembly 200 is disposed in the washing cavity, and the shelf assembly 200 includes at least a first shelf 210 disposed at the bottom of the washing cavity for supporting the item 400 to be washed.

[0074] In another embodiment, the spray assembly 300 includes a bottom spray member 310, at least two replaceable spray members 320, and a support member 330 disposed between the bottom spray member 310 and the replaceable spray members 320.

[0075] The bottom spray element 310 is disposed on the upper or lower side of the first shelf 210 and connected to the water supply component. The bottom spray element 310 has spray holes 322 with openings facing the first shelf 210. The bottom spray element 310 outputs washing water upward to clean the item 400 to be cleaned.

[0076] Refer again Figure 2 , Figure 3 In some embodiments of this application, the shelf assembly 200 specifically includes a first shelf 210 and a second shelf 220, that is, at least a double-layer support structure is provided in the washing cavity.

[0077] The first shelf 210 and the second shelf 220 are spaced apart along the depth direction of the washing cavity, and the replaceable spray element 320 is located between the first shelf 210 and the second shelf 220.

[0078] The bottom spray component 310 can be a fixed structure or rotatably connected above or below the first shelf 210.

[0079] The spray holes 322 on the bottom spray member 310 are arranged in the same inclined direction. In the washing state, under the reaction of the washing water output from the spray holes 322, the bottom spray member 310 rotates and sprays the washing water evenly into the washing cavity to clean the items to be cleaned.

[0080] Refer again Figure 2 , Figure 3 In some embodiments of this application, the shelf assembly 200 specifically includes a first shelf 210 and a second shelf 220, that is, at least a double-layer support structure is provided in the washing cavity.

[0081] The first shelf 210 and the second shelf 220 are spaced apart along the depth direction of the washing cavity, and the replaceable spray element 320 is located between the first shelf 210 and the second shelf 220.

[0082] In addition to spraying and cleaning the parts 400 to be cleaned on the first shelf 210 together with the bottom sprayer 310, the replaceable sprayer 320 can also clean the parts 400 to be cleaned on the second shelf 220 according to the user's actual needs, so as to improve cleaning efficiency.

[0083] The second shelf 220 is detachably connected to the washing cavity to facilitate the placement and removal of the item 400 to be washed on the first shelf 210. Specifically, an inner support protrusion extending into the washing cavity is formed on the side wall of the washing cavity, and the second shelf 220 is supported on the inner support protrusion.

[0084] Of course, the second shelf 220 can also be connected by other detachable means such as snap-fit, but the specific connection is not the focus of this application and will not be described in detail here.

[0085] The cleaning equipment has two shelves, which can clean 400 layers of different sizes of items, resulting in a larger capacity and better cleaning effect. Each shelf is equipped with a spray nozzle at the bottom, which improves cleaning efficiency and reduces blind spots.

[0086] refer to Figure 6 In some embodiments of this application, one of the replaceable spray components 320 is a spray arm structure with a through connection hole 321 formed thereon. The replaceable spray component 320 specifically includes at least two spray arms arranged at equal angles along the periphery of the connection hole 321. Each spray arm has a spray channel formed thereon, and the spray channel is connected to the water supply channel through the connection hole 321. Each spray arm has a spray surface with the same orientation, and a plurality of spray holes 322 are arranged at intervals on the spray surface. A cover portion 350 is detachably connected to the connection hole 321 for sealing the top of the connection hole 321.

[0087] Specifically, with the second shelf 220 connected to the washing chamber, the replaceable spray members 320 are configured with each spray surface facing the second shelf 220 for cleaning the items 400 to be cleaned on the second shelf 220.

[0088] With the second shelf 220 removed from the washing chamber, the replaceable spray members 320 are configured with each spray surface facing the first shelf 210 for cleaning the items 400 to be cleaned on the first shelf 210.

[0089] In other words, the replaceable spray component 320 can be installed on both sides according to the actual washing requirements. That is, its spray surface can face the second shelf 220 or the first shelf 210. After the replaceable spray component 320 is installed, the specific spray direction of the replaceable spray component 320 can be adjusted by simply covering the connecting hole 321 with the cover part 350.

[0090] The above-described structure of the replaceable spray component 320 enables multi-functional washing of the cleaning equipment. It can perform bi-directional cleaning of the items 400 to be cleaned on the first shelf 210 from both top and bottom, improving the cleaning effect. Alternatively, the bottom spray component 310 and the replaceable spray component 320 can be used to clean the items 400 to be cleaned on the first shelf 210 and the second shelf 220 respectively. It has a large washing capacity, stronger versatility, and is simple and convenient to operate.

[0091] Combination Figures 7-11 In some embodiments of this application, the replaceable spray member 320 is detachably connected to the top of the support member 330 via an adapter 340. The adapter 340 has a plurality of connecting portions 342 formed on its periphery. The spray channel is connected to the water supply channel through the corresponding connecting portions 342. The cover portion 350 is connected to the adapter 340. The replaceable spray member 320 is rotatably connected to the adapter 340.

[0092] The adapter 340 includes a first connecting end 344 and a second connecting end 341. The first connecting end 344 is a cylindrical structure, and the second connecting end 341 is a cylindrical structure that is at least partially closed at the top. A through connecting channel is formed in the first connecting end 344 and the second connecting end 341.

[0093] The first connecting end 344 is sleeved on the top of the uppermost adjustable support unit 332. Specifically, a snap-fit ​​hole 3321 is provided on the outer wall of the uppermost support member 330, and a snap-fit ​​block 345 is provided on the inner wall of the second connecting end 341. In the connected state, the snap-fit ​​block 345 snaps into the snap-fit ​​hole 3321 to realize the connection and fixation between the second connecting end 341 and the support member 330.

[0094] Specifically, a groove 246 is provided on the second connecting end 341. The groove 246 is specifically located on both sides of the locking block 345. A reset arc plate is formed between the two grooves 246. The reset arc plate has a certain amount of deformation. When the second connecting end 341 is connected to the support member 330, the reset arc plate expands outward under the action of the locking block 345 until the locking block 345 is engaged in the locking hole 3321. Then the reset arc plate is reset, so as to reduce the friction between the second connecting end 341 and the support member 330 during the installation process and improve the assembly efficiency.

[0095] In addition, please refer to the specific details. Figure 9 In order to support and limit the replaceable spray component 320, a limiting protrusion 343 is formed between the first connecting end 344 and the second connecting end 341, extending radially outward along the first connecting end 344. The size of the connecting hole 321 of the replaceable spray component 320 is larger than the outer diameter of the second connecting end 341, and the outer diameter of the limiting protrusion 343 is larger than the connecting hole 321. The replaceable spray component 320 is sleeved on the adapter 340 from above the second connecting end 341 through the connecting hole 321, and is rotatably connected above the limiting protrusion 343.

[0096] The second connecting end 341 is a cylindrical structure with a closed top, and the connecting part 342 is formed on the periphery of the second connecting end 341.

[0097] Washing water, transported upward from the water supply channel, is conveyed through the connecting part 342 to the spray channel, and finally output from the spray holes 322 on the spray arm.

[0098] The cover portion 350 is specifically connected to the second connecting end 341. The outer diameter of the cover portion 350 is adapted to the size of the connecting hole 321, and the inner diameter is adapted to the outer diameter of the second connecting end 341. The cover portion 350 is fixedly connected to the second connecting end 341. The cover portion 350 is connected inside the connecting hole 321, and the replaceable spray component 320 is rotatably connected to the cover portion 350.

[0099] For details, please refer to the following: Figure 10 The top of the cover portion 350 also has a positioning outer edge 351 extending to the periphery. The positioning outer edge 351 is located outside the replaceable spray member 320 and is used to limit the replaceable spray member 320. It can also reduce the gap between the connecting hole 321 and the cover portion 350 and reduce the leakage of washing water from the replaceable spray member 320 and the cover portion 350.

[0100] Thus, the replaceable spray component 320 is rotatably connected between the positioning outer edge 351 and the limiting protrusion 343.

[0101] In some embodiments, the cover portion 350 is snapped onto the second connecting end 341. A plurality of snap-fit ​​portions 352 are distributed along the circumferential direction on the cover portion 350. The snap-fit ​​portions 352 are specifically formed on the inner surface of the cover portion 350 and extend downward. A snap-fit ​​portion 347 is formed on the second connecting end 341, and the snap-fit ​​portion 352 is connected to the corresponding snap-fit ​​portion 347.

[0102] Specifically, the latching portion 347 is a latching protrusion formed on the connecting portion 342, and the snap-fit ​​portion 352 is correspondingly connected to the latching protrusion.

[0103] Combination Figure 12 , Figure 13 In other embodiments, the cap portion 350 is adsorbed onto the adapter 340, the second connecting portion is provided with a first adsorption portion 361, the cap portion 350 is provided with a second adsorption portion 362, and the second adsorption portion 362 is connected to the first adsorption portion 361 by magnetic attraction, so as to realize the detachable connection between the cap portion 350 and the adapter 340.

[0104] refer to Figures 14-16 In some other embodiments, a spray end face is formed on one of the replaceable spray members 320, the spray end face is located at the far end where the replaceable spray member 320 is connected to the adapter, and a plurality of through spray nozzles 323 are dispersed on the spray end face.

[0105] The number and specific size of the spray nozzles 323 are designed according to actual needs. Specifically, the spray nozzles 323 are through water inlets formed on the spray end face, and the water flow in the water supply channel is directly output from the spray nozzles 323 to the washing inner cavity.

[0106] The replaceable spray unit 320 is mainly designed for bottle-shaped components 400 with large openings and deep depths. In use, the component 400 is placed upside down on the first shelf, and the replaceable spray unit 320 extends into the inner cavity of the component 400. In addition to the bottom spray unit 310 located on the lower layer spraying the component 400 over a wide area, the concentrated water flow output from the spray nozzle 323 on the replaceable spray unit 320 can also powerfully clean the inner cavity of the component 400.

[0107] In some embodiments, the inner side of the spray end face of the replaceable spray member 320 is provided with a plurality of snap-fit ​​portions 352 distributed along the circumferential direction, and a snap-fit ​​portion 347 is formed on the second connecting end 341, with the snap-fit ​​portion 352 connected to the corresponding snap-fit ​​portion 347.

[0108] The specific structures of the latching part 352 and the engaging part 347 are similar to those in the above embodiments, and will not be described in detail here.

[0109] The second connecting end 341 is provided with a first adsorption part, and the spray end face is formed with a second adsorption part. The second adsorption part is connected to the first adsorption part by magnetic attraction, so as to realize the detachable connection between the replaceable spray part 320 and the adapter.

[0110] It should be noted that, in order to enable the washing water in the adapter to be transported to the spray nozzle 323 through the connecting part 342, the second connecting end 341 is designed to have an outwardly extending sealing edge 3411 on the side near the limiting protrusion 343. The size of the sealing edge 3411 is smaller than that of the limiting protrusion 343. The bottom of the replaceable spray member 320 is connected to the sealing edge 3411, and an overflow gap is formed between the outer wall of the second connecting end 341 and the inner wall of the replaceable spray member 320.

[0111] The water flow from the connecting part 342 is output outward through the flow gap, and is output through the spray nozzle 323, the spray column 324 or the spray channel.

[0112] refer to Figure 17 , Figure 18 In other embodiments, a spray end face is formed on one of the replaceable spray members 320, the spray end face is located at the far end where the replaceable spray member 320 is connected to the adapter, and a spray column 324 extending in a direction away from the adapter is formed on the spray end face, and a spray channel communicating with the water supply channel is formed on the spray column 324.

[0113] The difference between this replaceable spray component 320 and the replaceable spray component 320 in the previous embodiment is that an upwardly extending spray column 324 is formed on the spray end face.

[0114] The replaceable spray unit 320 is mainly designed for bottle-shaped or tubular items 400 with small opening sizes.

[0115] During cleaning, the bottle-shaped or tubular part 400 to be cleaned with a small opening is inverted onto the corresponding spray column 324. In addition to the bottom spray component 310 located at the lower layer spraying the part 400 over a wide area, the concentrated water flow output from the spray column 324 on the alternative spray component 320 can also powerfully clean the inner cavity of the part 400 to be cleaned.

[0116] The replaceable spray unit 320 can also be connected to the adapter via a snap or magnetic connection.

[0117] The cleaning equipment involved in this application includes at least two of the above three replaceable spray components 320, and the connection method between each replaceable spray component 320 and the adapter is uniform to achieve detachable connection.

[0118] Combining 13, Figure 16 as well as Figure 18In addition, in some embodiments, in order to reduce the vortex formed by the water flow on the lower side of the second connection end 341 and reduce the upward force on the second connection end 341, this application forms a guide portion 348 extending in the direction of the water supply channel at the top of the second connection end 341. The guide portion 348 is used to guide the water flow output from the water supply channel to the periphery.

[0119] The guide section 348 is specifically a guide arc surface structure that gradually narrows from the top periphery of the second connecting end 341 towards the center. Under the action of the guide section 348, the water flow is guided towards the peripheral connecting section 342 to reduce the force of the water flow on the second connecting end 341.

[0120] In some embodiments, the height of the support 330 is adjustable, thereby adjusting the height of the replaceable spray member 320 to match the position of the item 400 to be cleaned in the washing cavity and improve the cleaning effect.

[0121] Specifically, when the height of the item to be cleaned 400 on the first shelf 210 is low, the height of the support 330 is lowered, and the replaceable sprayer 320 is moved above the item to be cleaned 400 and closer to the item to be cleaned, thereby increasing the impact force of the washing water sprayed from the replaceable sprayer 320 on the item to be cleaned 400.

[0122] When the height of the item 400 to be cleaned on the first shelf 210 is high, such as a baby bottle, the height of the support 330 is adjusted to match the item 400 to be cleaned.

[0123] Specifically, in combination Figures 5-7 The support member 330 includes at least two support units connected end to end. The support member 330 is configured to adjust its height by changing the relative position of adjacent support units. Specifically, the adjacent support units are movably connected by plugging in each other. The height of the entire support member 330 can be adjusted according to the depth of the plugging in between the adjacent support units.

[0124] A water supply channel is formed within the support member 330, which is used to connect the bottom spray member 310 and the replaceable spray member 320.

[0125] refer to, Figures 19-21 In some embodiments, the support member 330 is vertically arranged and includes a bottom support unit 331 connected to the first shelf 210 and at least one adjustable support unit 332 movably connected to the bottom support unit 331. The bottom spray member 310 is rotatably connected below the bottom support unit 331, and the replaceable spray member 320 is rotatably connected to the topmost adjustable support unit 332.

[0126] To facilitate processing, the bottom support unit 331 is designed to be integrally formed with the first shelf 210. Specifically, the bottom support unit 331 is a tubular structure formed in the middle of the first shelf 210 and extending upward. The middle of the first shelf 210 also has a through hole that communicates with the inner cavity of the bottom support unit 331. The bottom spray component 310 is connected to the bottom support unit 331 through the through hole.

[0127] The number of adjustable support units 332 can be designed to be one or more depending on the actual design requirements.

[0128] When there is only one adjustable support unit 332, the bottom of the adjustable support unit 332 is inserted into the bottom support unit 331 and can move up and down within a certain range relative to the bottom support unit 331.

[0129] When there are two or more adjustable support units 332, the adjustable support unit 332 at the bottom is inserted into the bottom support unit 331, and it and the adjustable support unit 332 are inserted into the adjacent adjustable support units 332 from top to bottom.

[0130] Along the top-to-bottom direction, the diameter of each adjustable support unit 332 gradually increases.

[0131] In order to limit the movement of the adjustable support unit 332, a limiting recess 333 is formed on the bottom support unit 331 and / or the adjustable support unit 332, which is recessed into the water supply channel.

[0132] When there is only one adjustable support unit 332, the bottom of the adjustable support unit 332 is inserted into the bottom support unit 331 and can move up and down within a certain range relative to the bottom support unit 331.

[0133] Specifically, the bottom support unit 331 has a limiting recess 333 recessed into the water supply channel at both ends. The inner diameter of the limiting recess 333 is adapted to the outer wall size of the adjustable support unit 332 connected above it. A positioning part 334 is provided on the outer wall of the end of the adjustable support unit 332 that extends into the bottom support unit 331. The positioning part 334 and the corresponding limiting recess 333 are used to limit the maximum displacement of the adjustable support unit 332 relative to the bottom support unit 331.

[0134] When there are two or more adjustable support units 332, the adjustable support unit 332 at the bottom is inserted into the bottom support unit 331, and it and the adjustable support unit 332 are inserted into the adjacent adjustable support units 332 from top to bottom.

[0135] Except for the topmost adjustable support unit 332 which is directly connected to the spray unit, at least one end of each of the other adjustable support units 332 is formed with a limiting recess 333 that is recessed into the water supply channel, and a positioning part 334 is provided at one end of each adjustable support unit 332 that extends into the adjacent adjustable support unit 332.

[0136] The inner diameter of the limiting recess 333 is adapted to the outer wall size of the adjustable support unit 332 connected above it, and a tight connection is formed between the limiting recess 333 and the adjustable support unit 332 connected thereto, ensuring sealing and preventing water leakage.

[0137] When the adjustable support unit 332 moves up and down along the bottom support unit 331 or the adjacent adjustable support unit 332, the positioning part 334 connected to it moves synchronously until the positioning part 334 contacts the limiting recess 333, at which point the adjustable support unit 332 is adjusted into position.

[0138] Specifically, at least two positioning holes are provided at equal angles along the circumference of the lower position of the adjustable support unit 332. The positioning part 334 is specifically a positioning arc plate, on which a positioning protrusion is formed. The positioning part 334 is connected to the outer wall of the adjustable support unit 332 through the positioning protrusion.

[0139] The positioning protrusion can be formed by stamping. Taking the installation of the bottom support unit 331 and the adjacent adjustable support unit 332 as an example:

[0140] First, a limiting recess 333 is machined at the first end of the bottom support unit 331. The positioning part 334 is connected to the positioning hole of the adjustable support unit 332. Then, one end of the adjustable support unit 332 with the positioning part 334 is inserted from the second end of the bottom support unit 331. Finally, the limiting recess 333 at the second end of the bottom support unit 331 is machined into shape.

[0141] Specifically, in order to facilitate processing and assembly, in addition to the bottom support unit 331 located at the bottom of the adjustable support 330, each adjustable support unit 332 is provided with a limiting recess 333 at the end away from the positioning hole. That is, the limiting recess 333 is located at the upper end of each adjustable support unit 332, and the lower end of each adjustable support unit 332 is limited by the bottom support unit 331 or the positioning part 334 on the adjustable support unit 332 connected to it.

[0142] The positioning protrusion on the positioning part 334 extends from the positioning hole on the adjustable support unit 332 into the interior of the adjustable support unit 332, and can limit the downward movement of the adjacent adjustable support unit 332 connected above it.

[0143] Combination Figure 22, Figure 23 In some embodiments of this application, in order to support and limit the cleaning component 400 on the first shelf 210 and to clean the inner cavity of the bottle-shaped cleaning component 400 on the first shelf 210, this application designs the first shelf 210 to be provided with a first support stand 230 and a second support stand 240.

[0144] A cleaning outlet is formed on the first support upright 230, and a water conveying channel communicating with the cleaning outlet is formed inside the first support upright 230. The water conveying channel is connected to the water supply channel through the conveying part 250, and the conveying part 250 is connected to the first shelf 210.

[0145] The first support upright 230, the second support upright 240 and the first shelf 210 are integrally formed. The second support upright 240 is a support column structure, which improves the limiting support effect for the large opening of the part to be cleaned 400.

[0146] The top of the first support stand 230 also has a cleaning function, making it more suitable for bottle-shaped items 400 with small openings, such as baby bottles, that need to be cleaned.

[0147] For ease of processing, the conveying section 250 includes a first conveying housing 251 and a second conveying housing 252. A water supply channel is formed between the first conveying housing 251 and the second conveying housing 252. The first conveying housing 251 is integrally formed at the bottom of the first shelf 210, and the second conveying housing 252 is detachably connected to the first conveying housing 251.

[0148] The second conveying housing 252 and the first conveying housing 251 can be detachably connected by a snap-fit, or they can be connected and fixed by fasteners or other means, without any specific limitation.

[0149] The cleaning equipment involved in this application includes a spray assembly 300 comprising a bottom spray component 310 and a replaceable spray component 320 spaced apart vertically. The bottom spray component 310 and the replaceable spray component 320 can clean the item 400 placed on the first shelf 210 according to the user's actual needs, which is beneficial for cleaning the item 400 from all angles. In addition, the height of the replaceable spray component 320 relative to the bottom spray component 310 is adjustable under the action of the support component 330, so that the height of the replaceable spray component 320 can be adjusted according to the height of the item 400 to be cleaned on the first shelf 210, thereby improving the cleaning effect.

[0150] In addition, the bottom spray unit 310 and the replaceable spray unit 320 can also clean the items 400 to be cleaned on the first shelf 210 and the second shelf 220 respectively. The first shelf 210 and the second shelf 220 are arranged at intervals in the washing cavity. The spray surface on the replaceable spray unit 320 can be adjusted to face upwards to clean the items 400 to be cleaned on the second shelf 220 located above the replaceable spray unit 320. This method is beneficial to increase the capacity of the washing cavity and to perform layered cleaning of items 400 with different heights, which helps to reduce cleaning blind spots.
