Description

A baby bottle cleaning machine structure Technical Field

[0001] This invention belongs to the field of cleaning machine technology, and particularly relates to a structure for a baby bottle cleaning machine. Background Technology

[0002] Baby bottles are containers used to hold dairy products. For infants who do not consume breast milk, baby bottles are an essential feeding utensil. Because infants are weak and have poor immunity, the requirements for baby bottles are very high. Before feeding an infant, it is essential to ensure that the baby bottle is clean. Therefore, baby bottles and their accessories need to be cleaned frequently, which undoubtedly consumes a lot of time and energy. Meanwhile, mothers need to dedicate even more time to caring for their babies. As a result, baby bottle cleaning machines have gradually become the best cleaning tool for cleaning infant bottles, bottle accessories, pacifiers, breast pump cups, and other related items.

[0003] Commercially available bottle washers often leave large water droplets on the surface of bottles and other items after washing. These droplets, after drying, can easily form water stains or marks, making the surfaces appear unclean. Furthermore, the large water droplets prolong drying time, reducing the user experience. Most commercially available bottle washers also operate on a dishwasher principle, where items are fixed in place and a rotating water arm creates a converging flow of water to clean the surfaces, combined with detergent. While this rotating water arm design can effectively clean bottles, it consumes water pressure during the cleaning process, affecting the cleaning effect.

[0004] In addition, existing bottle cleaning machines typically include a water supply system, a hollow column, a bottle holder, a nipple holder, and a spray arm mounted on the column. In use, the bottle is usually placed upside down on the bottle holder, and the nozzle on the bottle holder is used to clean the inside of the bottle, while the water spray holes on the spray arm are used to clean the outside of the bottle. In existing technology, the spray arm is directly fitted onto the column, and then the nipple holder is pressed down on the spray arm from above. However, this connection is unstable. Because the spray arm generates a reverse thrust when spraying water downwards, it is easy for it to slide upwards and the water channel inside the spray arm to lose contact with the water channel inside the column, thus affecting the spraying effect of the spray arm.

[0005] To overcome the aforementioned technical deficiencies, Chinese patent document CN223126466U discloses a spray device for a baby bottle washing machine and the baby bottle washing machine itself, comprising: a base frame with a water supply assembly; a water guide column with a water channel extending upwards and communicating with the water supply assembly; and an upper spray arm; a locking assembly is provided between the upper spray arm and the water guide column to engage the upper spray arm with the water guide column; the locking assembly includes a first locking part located on the upper spray arm and having elasticity, and a second locking part located on the outer wall of the water guide column; the first locking part engages with the second locking part under the action of elasticity. The locking assembly forms a stable connection between the upper spray arm and the water guide column, preventing the upper spray arm from sliding relative to the water guide column. The second locking part is a locking block, which is an annular locking block arranged around the water guide column, with an elastic hook hooking onto the lower side of the annular locking block and rotatable around the annular locking block. By setting two elastic hooks on opposite sides, the forces on both sides are balanced, making it more stable; by setting the locking block as a ring-shaped locking block around the water guide column, the elastic hooks can rotate around the ring-shaped locking block when the upper spray arm rotates to spray water, so that they are always hooked on the locking block.

[0006] In the aforementioned patent literature's technical solution, during bottle cleaning, the upper and lower spray arms continuously rotate under the action of water flow, thus creating a dynamic cleaning effect. However, the bottle remains stationary, leading to blind spots (such as the bottom of the bottle and the inside of the nipple) that cannot be rinsed by the continuous water flow, resulting in incomplete cleaning. Furthermore, after cleaning, water droplets remain on the top and sides of the bottle. Once the bottle is dried, impurities from the cleaning water can form watermarks on the bottle's surface. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a spray-type baby bottle cleaner. This spray-type baby bottle cleaner uses a rotating basket to spin dry large water droplets, reducing water stains and marks on the inner and outer surfaces of the baby bottle or nipple, shortening the drying time, reducing energy consumption, and improving the user experience.

[0008] A spray-type baby bottle cleaner includes a cylindrical shell with a cleaning chamber inside. The cleaning chamber has at least one rotatable basket and a rotating water spraying mechanism for spraying water into the cleaning chamber.

[0014] As described above, the spray-type baby bottle cleaner has a steam sterilization device inside the cylinder shell for sterilizing the items in the cleaning chamber.

[0015] As described above, the spray-type baby bottle washing machine has a hot air blower inside the cylindrical shell for drying the items inside the washing chamber.

[0016] As described above, the spray-type baby bottle cleaner has an upper cover on the cylinder shell that is adapted to movably fit the cylinder shell.

[0017] Compared with the prior art, the present invention has the following advantages: 1. After the cleaning work is completed, the adjustable rotation drive mechanism drives the basket to rotate rapidly, thereby achieving the effect of shaking off large water droplets, reducing water stains and watermarks on the inner and outer surfaces of the object, shortening the drying time, reducing energy consumption, and improving the user experience.

[0018] 2. The cleaning device of the present invention fixes the object in a rotatable basket. During cleaning, the rotation drive mechanism drives the basket to rotate slowly, so that the object is evenly rinsed by water, resulting in a good rinsing effect.

[0019] The present invention features a fixed water nozzle spraying method, resulting in minimal water pressure loss. The rotating water spraying mechanism of the present invention is not limited to the vertical spraying of the central column; nozzles can also be set around the machine body to achieve a three-dimensional spraying effect, ensuring thorough cleaning without dead angles.

[0020] This invention effectively prevents items from being accidentally thrown off when the storage basket rotates by providing guardrails of a certain height around the perimeter of the storage board, thus effectively protecting the items.

[0021] Another objective of this invention is to provide a baby bottle cleaning machine structure that addresses the problems of incomplete cleaning and watermark formation on the surface after cleaning and drying in existing baby bottle cleaning machines.

[0022] To achieve the above objectives, this invention provides a baby bottle cleaning machine structure, including a cylindrical shell, a rotary drive mechanism, a storage basket, a water pumping device, and a rotary spraying mechanism. The cylindrical shell contains a cleaning chamber, and a base plate is provided at the bottom of the cleaning chamber, forming an installation cavity with the bottom of the cylindrical shell. The rotary drive mechanism is located within the installation cavity, and its rotating end has a rotating shaft. The upper end of the rotating shaft passes through the base plate and extends into the cleaning chamber. The storage basket is supported at the upper end of the rotating shaft and has multiple support positions. The rotary spraying mechanism includes an annular ring located at the bottom of the storage basket. A water flow channel is provided within the annular ring, and multiple water jets are provided on the annular ring. These water jets extend into the storage basket and rotate with it. The water pumping device is connected to the water flow channel.

[0023] Furthermore, the water pumping device includes a water pump and an annular channel. The annular channel is fitted around the outside of the rotating shaft, and a connecting channel extends from one side of the annular channel. The water pump is located at one end of the connecting channel. The annular channel is provided with an annular outlet, and the bottom of the annular ring is provided with an inlet located above the annular outlet.

[0024] Furthermore, the annular outlet has an upward-extending guide ring at its opening, and the inlet has a downward-extending baffle ring at its opening, with the baffle ring fitted around the outside of the guide ring.

[0025] Furthermore, the annular channel includes an inner ring that extends upward into the annular ring, and a baffle plate extends outward from the upper end of the inner ring; the top side of the annular ring is provided with an opening that fits around the outside of the baffle plate.

[0026] Furthermore, both the inner wall of the water-blocking ring and the inner wall of the opening are provided with water-blocking strips, and the cross-section of the water-blocking strips is semi-circular.

[0027] Furthermore, several fixed spray arms extend from the outer side of the annular channel, each fixed spray arm including multiple nozzles facing different directions; the fixed spray arms are supported at the bottom of the cleaning chamber; and the bottom of the storage basket is provided with several clearance grooves.

[0028] Furthermore, the water pump includes a circulation pump, which has an inlet end and an outlet end, and the outlet end is connected to the connecting channel; the base plate is provided with a return channel, which is connected to the inlet end of the circulation pump.

[0029] Furthermore, a water tank is provided on one side of the cylindrical shell, and a water inlet pump is provided in the mounting cavity. The water inlet pump is connected to the water tank and the cleaning cavity. The water pump also includes a drain pump. The drain pump is connected to the return channel.

[0030] Furthermore, the bottom of the storage basket is provided with an upwardly extending connecting post, the connecting post is provided with a positioning hole, the top side of the annular ring is provided with a positioning post extending into the positioning hole, and the locking screw passes through the top side of the connecting post and connects with the positioning post; the top side of the water spray column is provided with multiple water spray holes facing different directions.

[0031] Furthermore, a hot air blower is provided inside the installation cavity, and an air duct is provided on one side of the cylinder shell. The lower end of the air duct is connected to the cleaning cavity, and the upper end of the air duct is connected to the hot air blower pipe.

[0032] The above-mentioned technical solutions of one or more of the baby bottle cleaning machine structure provided by the present invention have at least the following technical effects: 1. Baby bottles, nipples and other items that need to be cleaned are placed in the various support positions of the storage basket. The water pumping device pumps cleaning water into the annular water flow channel. The water flow in the water flow channel is transported into the water spray column, and then the water spray column sprays water onto the items to be cleaned, so as to achieve point-to-point cleaning of the items, avoid the formation of dead corners, and make the cleaning more thorough.

[0033] 2. During the cleaning process, the rotating drive mechanism can drive the storage basket and the rotating water spray mechanism to rotate together, which can realize dynamic cleaning of the objects and achieve all-round cleaning of the objects.

[0034] 3. After the washing is completed, the basket can be rotated by the rotary drive mechanism. Under the action of centrifugal force, water droplets on the cleaned items can be removed from the surface of the items. This not only improves the drying efficiency, but also effectively avoids watermarks on the surface of the cleaned items. Attached Figure Description

[0056] As shown in Figures 1-3, a spray-type baby bottle cleaner of the present invention includes a cylindrical shell 100, a cleaning chamber 101 inside the cylindrical shell 100, at least one rotatable storage basket 300 inside the cleaning chamber 101, and a rotating water spraying mechanism 500 for spraying water into the cleaning chamber 101 to clean items placed on the storage basket 300. At least one rotating shaft 210 penetrating through the bottom plate of the cleaning chamber 101 is provided inside the cleaning chamber 101, and the storage basket 300 is correspondingly fixed to the rotating shaft 210. Below the rotating shaft 210 is a rotating drive mechanism 200 that drives the rotating shaft 210 to rotate and whose speed is adjustable. The items mainly cleaned by the present invention include baby bottles and accessories, breast pump cups and accessories, and other baby items, such as pacifiers and teething rings.

[0057] This invention features at least one rotatable basket 300 within the cleaning chamber 101, which holds items in place. During cleaning, an adjustable-speed rotary drive mechanism 200 drives the basket 300, fixed to a rotating shaft 210, to rotate slowly, ensuring the items are evenly rinsed with water. A rotating water spray mechanism 500 sprays water onto the items inside. After cleaning, the adjustable-speed rotary drive mechanism 200 drives the basket 300 to rotate rapidly, shaking off large water droplets from the items. This reduces water stains and marks on the inner and outer surfaces of bottles 21, nipples 22, breast pump cups and accessories, and other baby items, shortens drying time, reduces energy consumption, and improves the user experience.

[0058] In this invention, there is at least one storage basket 300, or there can be two or more. Multiple storage baskets 300 can be stacked or set independently and separately in the cleaning chamber 101. The rotatable storage basket 300 can be storage baskets of various shapes. In order to increase the utilization space, in actual operation, a round storage basket 300 is generally selected to match the cylindrical or square cleaning chamber 101.

[0059] Specifically, as shown in Figures 3-4, a gear 211 is provided on the rotating shaft 210. The rotating drive mechanism 200 of this embodiment includes a drive motor 220 with controllable rotation speed, and a belt 230 connected between the gear of the drive motor 220 and the gear 211 of the rotating shaft 210.

[0060] The present invention may also include several rotating shafts 210 penetrating the bottom plate of the cleaning chamber 101 within the cleaning chamber 101. A storage basket 300 is fixedly attached above each rotating shaft 210, and the lower part of each rotating shaft 210 can be driven to rotate by the same rotating drive mechanism 200. In practical applications, the embodiment is generally adopted, where a rotating shaft 210 penetrating the bottom plate of the cleaning chamber 101 is located at or near the center of the cleaning chamber 101, and the storage basket 300 is fixedly attached to the rotating shaft 210. This saves costs and increases space utilization.

[0061] As shown in Figures 1-3 and 5, the storage basket 300 of the present invention includes a storage plate 310 and a guardrail 320 of a certain height surrounding the storage plate 310. The storage basket 300 has several perforated structures 330 for water drainage. The guardrail 320 of a certain height around the storage plate 310 effectively prevents items from being accidentally thrown off when the storage basket 300 rotates, thus effectively protecting the items. The perforated structures 330 on the storage basket 300 ensure that water can smoothly enter the storage basket 300 to wash the items inside, and can also smoothly flow out from the top, which can also speed up the spin-drying and drying of the items.

[0062] As shown in Figures 2 and 5, the storage basket 300 of this invention is provided with a support position 301. The support position 301 is used to fix the baby bottle 21 and prevent the baby bottle 21 from shaking and accidentally breaking when the storage basket 300 rotates and the cleaning chamber 101.

[0063] As shown in Figures 3 and 5, the cleaning chamber 101 is provided with at least two stacked storage baskets 300. The cleaning chamber 101 also includes a support structure 340 for connecting and supporting the upper storage basket 300, with both ends of the support structure 340 positioned between the upper storage basket 300 and the rotating shaft 210. The stacked storage baskets 300 further increase the usable space of the cleaning chamber 101 and allow for the washing of more items such as bottles 21 and nipples 22 from the storage baskets 300 at once.

[0064] As shown in Figures 1-3 and 5, the rotary water spray mechanism 500 of the present invention is fixedly installed inside the cleaning chamber 101. Using the same water pump and a fixed water nozzle spray method, water pressure loss is low and the rinsing effect is good. Specifically, the rotary water spray mechanism 500 includes a first spray structure 540 disposed within the rotating shaft 210 and extending upward to the upper part of the cleaning chamber 101. The first spray structure 540 is a hollow, water-permeable fixed shaft. Water can be sprayed out through the through hole 541 at the top of the fixed shaft. In this embodiment, the first spray structure 540 is disposed within the rotating shaft 210. During cleaning, the basket 300 rotates slowly, and water can be sprayed outward from the center onto the items inside the basket 300. This saves internal space in the cleaning chamber 101 and improves the spraying effect.

[0065] More specifically, the outer wall of the first spray structure 540 is provided with a number of first spray holes 542 that spray water upwards and a number of second spray holes 543 that spray water downwards, so that water can be sprayed from all directions to the baby bottles 21, nipples 22 and other items to be washed in the storage basket 300 around the first spray structure, so that the items in the storage basket 300 are washed cleaner.

[0066] As shown in Figures 2-5, the rotating water spray mechanism 500 includes a second spray structure 550 installed at the bottom of the cleaning chamber 101, which sprays water into the cleaning chamber 101 from bottom to top. In this embodiment, the second spray structure 550 is located at the bottom of the cleaning chamber 101, and the water flow sprays the items in the storage basket 300 from bottom to top. The water flow can also enter the interior of the baby bottle 21, further improving the washing effect.

[0067] The rotating water spray mechanism 500 of the present invention is not limited to the central column intersecting spray shown in the attached drawings of this embodiment. It can also be equipped with nozzles around the machine body to achieve a three-dimensional spraying effect and cleaning without dead angles; it can also use a rotatable spray arm for spraying.

[0068] As shown in Figures 3-5, the cylindrical shell 100 of the present invention is provided with a water tank 130 and a water pumping device 400, and the rotating water spraying mechanism 500 is connected to the water tank 130 through the water pumping device 400.

[0069] As shown in Figure 5, the cylindrical shell 100 is also equipped with a steam sterilization device 600 for sterilizing the items in the cleaning chamber 101 and a hot air blower 700 for drying the items in the cleaning chamber 101. Specifically, the steam sterilization device 600 includes a heating plate, a steam generator, etc., and is used to sterilize the items in the cleaning chamber 101 with steam after the cleaning work is completed; the hot air blower 700 is equipped with a fan, a heating device, and an air duct, and is used to blow air into the cleaning chamber 101 after the steam sterilization work is completed to dry the items on the storage basket 300; the cylindrical shell 100 is also equipped with a drainage device 13 connected to the bottom of the cleaning chamber 101 to drain the washing water in the cleaning chamber 101 to the outside of the cylindrical shell 100.

[0070] As shown in Figures 1 and 5, the cylindrical shell 100 of the present invention is provided with an upper cover 104 adapted to movably cover the cylindrical shell 100.

[0071] In one embodiment of the bottle washing machine structure of the present invention, referring to Figures 6 to 18, the bottle washing machine structure of this embodiment includes a cylindrical shell 100, a rotary drive mechanism 200, a storage basket 300, a water pump device 400, and a rotary spray mechanism 500. A washing chamber 101 is provided inside the cylindrical shell 100, and a bottom plate 110 is provided at the bottom of the washing chamber 101. The bottom plate 110 and the bottom of the cylindrical shell 100 form an installation cavity 102. Preferably, an inner liner 120 is provided inside the cylindrical shell 100, and the edge of the opening of the inner liner 120 is fastened to the edge of the opening of the cylindrical shell 100 to form a sealing structure. The bottom of the inner liner 120 forms the bottom plate 110, and the interior of the inner liner 120 forms the washing chamber 101.

[0072] Referring to Figures 8, 12, and 13, a rotary drive mechanism 200 is disposed within the mounting cavity 102. The rotary drive mechanism 200 has a rotating shaft 210 at its rotating end, with the upper end of the rotating shaft 210 extending through the base plate 110 into the cleaning cavity 101. Specifically, the rotary drive mechanism 200 includes a drive motor 220 and a transmission assembly (not shown in the figures). The drive motor 220 is disposed within the mounting cavity 102, and the transmission assembly connects the drive motor 220 and the rotating shaft 210, allowing the drive motor 220 to drive the rotating shaft 210 to rotate via the transmission assembly. The transmission assembly can be a pair of meshing bevel gears. Further, the base plate 110 has a downwardly extending first sleeve 111 at its bottom and an upwardly extending second sleeve 112 at its top. A partition 113 is disposed within the first sleeve 111. Bearings are disposed within the first sleeve 111 and the second sleeve 112, and the rotating shaft 210 extends into the cleaning cavity 101 through each bearing. Therefore, while the drive motor 220 can drive the rotating shaft 210 to rotate, it can also play a good role in waterproofing, preventing water in the cleaning chamber 101 from entering the installation chamber 102.

[0073] Referring to Figure 6, the storage basket 300 is supported on the upper end of the rotation shaft 210, and the storage basket 300 has multiple support positions 301. The support positions 301 are used to place items to be cleaned, such as baby bottles, nipples, and gravity balls. The structure of each support position 301 can be different, and is specifically defined according to the structure of the item being cleaned.

[0074] Referring to Figures 8 to 10 and 13 to 17, the rotating water spray mechanism 500 includes an annular ring 510, which is located at the bottom of the storage basket 300. A water flow channel 511 is provided within the annular ring 510, and multiple water jets 520 are provided on the annular ring 510. The water jets 520 extend into the storage basket 300 and rotate with the storage basket 300. Preferably, the annular ring 510 is fixedly installed at the bottom of the storage basket 300. Specifically, the bottom of the storage basket 300 has an upwardly extending connecting post 302, which has a positioning hole 303. The top side of the annular ring 510 has a positioning post 513 extending into the positioning hole 303, and a locking screw passes through the top side of the connecting post 302 and connects to the positioning post 513. A clearance position for the water jets 520 is provided at the bottom of the storage basket 300. Preferably, the top side of the water jets 520 has multiple water holes 521 facing different directions. Water can be sprayed in different directions from the water nozzles 521, which can increase the cleaning range.

[0075] Referring to Figures 10, 11 and 18, the water pump 400 is connected to the water flow channel 511, so that the water pump 400 can input cleaning water into the water flow channel 411. The water in the water flow channel 411 is injected into the water spray column 520, so that the water is sprayed out from the water spray column 520 and sprayed onto the items to be cleaned in the storage basket 300.

[0076] In this embodiment, items requiring cleaning, such as baby bottles and nipples, are placed in the support positions 301 of the storage basket 300. The water pumping device 400 pumps cleaning water into the water flow channel 511 of the annular ring 510. The water flow in the water flow channel 511 is then transported into the water spray column 520, which sprays water onto the items to be cleaned, achieving targeted cleaning and avoiding the problem of dead corners, thus making the cleaning more thorough. During the cleaning process, the rotating drive mechanism 200 can drive the storage basket 300 and the rotating water spray mechanism 500 to rotate together, enabling dynamic cleaning of the items and achieving all-round cleaning. After cleaning, the rotating drive mechanism 200 can drive the storage basket 300 to continue rotating. Under the action of centrifugal force, water droplets on the cleaned items can be removed from the surface of the items, which not only improves drying efficiency but also effectively avoids watermarks on the surface of the cleaned items.

[0077] Further referring to Figures 8 to 18, the water pumping device 400 includes a water pump 410 and an annular channel 420. The annular channel 420 is fitted around the outside of the rotating shaft 210, and a connecting channel 430 extends from one side of the annular channel 420. The water pump 410 is located at one end of the connecting channel 430. The annular channel 420 is provided with an annular outlet 421, and the bottom of the annular ring 510 is provided with an inlet 512 located above the annular outlet 421. In this embodiment, the water pump 410 pressurizes and pumps water into the annular channel 420, and the water is input into the water flow channel 511 of the annular ring 510 through the annular outlet 421 and the inlet 512.

[0078] Furthermore, referring to Figures 8, 13, 15, and 16, the annular outlet 421 has an upwardly extending guide ring 422, and the inlet 512 has a downwardly extending baffle ring 514, which is fitted around the outside of the guide ring 522. In this embodiment, the water flow for cleaning enters the annular ring 510, avoiding excessive water overflow.

[0079] Further referring to Figures 8 and 13, the annular channel 420 includes an inner ring 423 extending upward into the annular ring 510, with a baffle plate 424 extending outward from the upper end of the inner ring 423. An opening is provided on the top side of the annular ring 510, fitting around the outside of the baffle plate 424. In this embodiment, the inner ring 423 extending into the annular ring 510 facilitates water flow into the annular ring 510. Furthermore, the inner ring 423 and the baffle plate 424 isolate the rotating shaft 410, preventing water from spraying towards it.

[0080] Furthermore, referring to Figure 13, the bottom of the storage basket 300 is provided with a connecting sleeve 305, which extends into the inner ring 422, and the connecting shaft 210 is connected to the connecting sleeve 305. Additionally, the upper end of the first sleeve 111 extends into the inner ring 422. Therefore, the inner ring 422 can isolate the connection position of the rotating shaft 210, preventing water from entering and preventing splashing water from impacting the rotating shaft 410.

[0081] Furthermore, referring to Figure 16, both the inner wall of the water-blocking ring 514 and the inner wall of the opening are provided with water-blocking strips 515, the cross-section of which is semi-circular. The water-blocking strips 515 can further prevent water from overflowing from the gap between the water-blocking ring 515 and the guide ring 422, thus further serving a waterproof function.

[0082] Furthermore, referring to Figure 18, several fixed spray arms 440 extend from the outer side of the annular channel 420. Each fixed spray arm 440 includes multiple nozzles 441 facing different directions. The fixed spray arms 440 are supported at the bottom of the cleaning chamber 101, and the annular channel 420 is supported at the bottom of the inner liner 120 by the fixed spray arms 440 and the connecting channel 430. The bottom of the storage basket 300 is provided with several clearance grooves 303. In this embodiment, water is sprayed onto the items inside the storage basket 300 by the nozzles 441 of the fixed spray arms 440, forming an all-around cleaning process.

[0083] In this embodiment, more preferably, the cleaning method can be that the object to be cleaned is fixed in the support position 301, and the water pumping device 400 pumps water to make the fixed spray arm 440 and the water spray column 520 spray water onto the object to be cleaned. After cleaning for a period of time, the rotation drive mechanism 200 drives the storage basket 300 to rotate, thereby realizing dynamic cleaning. At the same time, the water spray column 520 keeps rotating synchronously with the object and rinses the object with water.

[0084] Further, referring to Figures 12, 13 and 18, the water pump 410 includes a circulation pump 411, which includes an inlet end 412 and an outlet end 413. The outlet end 413 is connected to the connecting channel 430. The base plate 110 is provided with a return channel 114, which is connected to the inlet end 412 of the circulation pump 411.

[0085] Preferably, the base plate 110 is inclined, and the return channel 114 is located at the bottom end of the base plate 110. More preferably, a cavity is also provided at the bottom end of the base plate 110, and the return channel 114 is located in the cavity, thereby facilitating water return and recycling.

[0086] Furthermore, referring to Figures 1 and 13, a water tank 130 is also provided on one side of the cylindrical shell 100, which stores cleaning water. An inlet pump 600 is also provided inside the mounting cavity 102, connecting the water tank 130 and the cleaning chamber 101. In this embodiment, during cleaning, the inlet pump 600 first pumps water from the water tank 130 into the cleaning chamber 101, and then the circulation pump 411 pumps water from the cleaning chamber 101 from the return channel 114 into the connecting channel 430. The connecting channel 430 transports the water to the annular channel 420, and then sprays it onto the object to be cleaned from the nozzle 441 and the water jet 520. The cleaning water is then recycled through the return channel 114.

[0087] Further referring to Figures 11 to 13, the water pump 410 also includes a drain pump 414; the drain pump 414 is connected to the return channel 114. In this embodiment, after cleaning is completed, the water in the cleaning chamber 101 can be drained by the drain pump 214.

[0088] Furthermore, referring to Figures 11 to 13, a hot air blower 700 is also provided inside the mounting cavity 102, and an air duct 800 is provided on one side of the cylinder shell 100. The lower end of the air duct 800 is connected to the cleaning cavity 101, and the upper end of the air duct 800 is connected to the hot air blower 700. After cleaning, hot air can be delivered into the cleaning cavity 101 by the hot air blower 700 to dry the cleaning cavity 101 and the objects in the cleaning cavity 101. Specifically, the hot air blower 700 delivers hot airflow from the upper end to the lower end of the air duct 800, and the hot airflow then enters the cleaning cavity 101 from the lower end of the air duct 800.

[0089] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
