Description

Technical Field

[0001] This invention belongs to the field of dishwasher technology, and particularly relates to a device for rapid cleaning of dishes. Background Technology

[0002] As a common cleaning appliance in modern kitchens, dishwashers' core function is to automatically clean dishes through water rinsing. Based on their structure, they can be categorized into built-in medium-to-large dishwashers, sink-integrated dishwashers, and small, movable countertop dishwashers. Current dishwashers generally employ a "stationary dishes + rotating nozzles" working mode, with water jets typically being non-fan-shaped direct streams. Water pressure is usually below 0.45 MPa, resulting in relatively weak water impact.

[0003] In actual use, the existing rinsing mechanism has the following significant defects: (1) Poor water coverage. Since the dishes are mostly stacked, the combination of the stationary dishes and the rotating nozzle makes it difficult for the water to penetrate the gaps in the dishes, and it is easy to form cleaning dead corners in the inner side and bottom of the dishes, which cannot achieve comprehensive cleaning; (2) Low cleaning efficiency. Due to the limitations of water flow characteristics and motion mode, the cleaning time of the existing dishwasher is usually as long as tens of minutes to several hours. It lacks the coordinated design of rotation and swing, and cannot achieve the synchronous improvement of cleaning efficiency and cleaning effect through the optimization of motion parameters, resulting in poor ease of use.

[0004] The aforementioned shortcomings of existing technologies make it difficult for current dishwashers to meet users' needs for fast, efficient, and thorough cleaning, especially in scenarios where small dishwashers are installed in already renovated kitchens. The performance limitations of existing rinsing mechanisms are even more pronounced, thus requiring urgent improvement. Summary of the Invention

[0005] The purpose of this invention is to solve the aforementioned technical problems in the prior art and to provide a quick dishwashing device. By optimizing the water flow pattern, motion coordination mode, and mechanism structure, this invention solves the problems of insufficient water flow impact, incomplete cleaning coverage, and low cleaning efficiency in the washing mechanisms of existing dishwashers.

[0015] Furthermore, the water supply components include a booster pump, which is connected to the water supply pipeline and is used to provide a high-pressure water flow.

[0016] Furthermore, the inner nozzle unit is connected to a fixed water supply passage via a rotary sealing assembly. The rotary sealing assembly is configured to allow the inner nozzle unit to rotate relative to the water supply passage and to maintain a waterproof seal at the connection point during rotation.

[0017] Furthermore, the water supply path includes a connecting pipe section, which is connected to the water supply pipe of the inner nozzle, and a rotary sealing assembly is located between the inner nozzle unit and the connecting pipe section.

[0018] Furthermore, the connecting pipe section and the water pipe of the inner nozzle are integrally formed and are fixedly connected to the fixed structure by locking nuts.

[0019] Furthermore, the rotary sealing assembly includes a sealing plug and a sealing ring fitted onto the end of the connecting pipe section, the inner nozzle unit being threadedly connected to the sealing plug, and the sealing ring being located between the sealing plug and the inner nozzle unit.

[0020] Furthermore, the second drive assembly includes a power mechanism and a transmission conversion mechanism connected in sequence. The transmission conversion mechanism is connected to the inner nozzle unit. The power mechanism outputs power and transmits the power through the transmission conversion mechanism to drive the inner nozzle unit in a scanning motion.

[0021] Furthermore, the power mechanism includes a main drive gear connected to the power source and a driven drive gear connected to the transmission conversion mechanism. The main drive gear and the driven drive gear mesh to output power.

[0029] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0030] 1. This invention utilizes the synergistic design of high-pressure fan-shaped water flow with the dish rack assembly and reciprocating oscillating nozzle to enable water flow to efficiently impact the inner and outer surfaces of the dishes at an angle, achieving second-level rinsing without dead angles, significantly shortening cleaning time, improving cleaning efficiency, and meeting users' needs for rapid cleaning.

[0031] 2. The high-pressure fan-shaped water jet of this invention has high energy concentration and strong impact force, which can directly remove stubborn oil stains without relying on special detergents, thus reducing usage costs and avoiding chemical residues. At the same time, the inner nozzle covers the swing trajectory from the edge of the dish rack assembly to the center area, and works with the outer nozzle to specifically rinse the outside of the dishes, thoroughly eliminating the cleaning dead corners of traditional rinsing modes and ensuring that the entire surface of the dishes is clean to the required standard.

[0032] 3. The linkage configuration of the drive component and the swing component of the present invention enables the inner nozzle unit to reciprocate at a swing frequency higher than the rotation speed of the bowl basket component during the washing process. This allows the high-pressure fan-shaped water jet sprayed by the inner nozzle to achieve a scanning and covering rinsing of the inner surface of the bowl within its spray range during one rotation of the bowl basket component.

Detailed Implementation

[0054] Example 1

[0055] like Figures 1 to 8 As shown, this invention provides a quick dishwashing device suitable for various small dishwashers, especially compact dishwashers that can be fixedly installed above the kitchen sink. Its core is to achieve quick and thorough cleaning of dishes through the coordinated design of the rotating dish rack assembly 11 and the high-pressure fan-shaped oscillating nozzle.

[0056] The dishwashing device of this embodiment includes a washing chamber 10, a dish basket assembly 11, a first drive assembly 20, a spray assembly 30, a water supply assembly 40, and a second drive assembly 50. The components work together to complete the dishwashing operation, which greatly shortens the washing time, improves the cleaning efficiency, and meets the user's need for quick cleaning.

[0057] The washing chamber 10 includes an inner liner 18 and a surrounding shell 17. The inner liner 18 and the surrounding shell 17 combine to form a receiving cavity, which, together with the chamber cover, forms a relatively enclosed washing space for accommodating dishes to be washed. The chamber cover is not shown in the attached drawings for clarity regarding the internal structure. The bottom of the washing chamber 10 has a mounting hole 12 for mounting the drive shaft 58 of the second drive assembly 50. Simultaneously, the bottom of the washing chamber 10 also has a drain outlet 13 connecting to the outside of the machine body. The drain outlet 13 connects to an external drain pipe, allowing for direct discharge of rinsing wastewater. This eliminates the need for a circulating water system, preventing pipe blockage and food residue buildup. Wastewater and detached food residue generated during washing can be directly discharged through the drain outlet 13, thus eliminating the need for tedious pre-cleaning of dishes; simple placement is sufficient for efficient cleaning, lowering the user's operational threshold.

[0058] like Figure 4 and Figure 8 As shown, the middle of the washing chamber 10 is connected to a dish basket assembly 11 via a rotating shaft 23. The dish basket assembly 11 includes a transmission component 14, a rotating basket 16, and a clamping component 15. The rotating basket 16 adopts a hollow mesh structure for placing dishes to be washed without stacking. Its bottom is connected to the rotating shaft 23 of the first drive assembly 20 via the transmission component 14, and can rotate at a constant speed around its own axis. The first drive assembly 20 drives the transmission component 14 to rotate, and the transmission component 14 drives the clamping component 15 to clamp the dishes to be washed. The clamping component 15 drives the rotating basket 16 to rotate by clamping the dishes to be washed.

[0059] When rotating in the forward direction, the rotating shaft 23 of the first drive assembly 20 drives the transmission component 14 to rotate in the forward direction. The transmission component 14 drives the clamping assembly 15 to move towards the center of the rotating basket 16, thereby clamping the dishes to be washed in the rotating basket 16. After clamping, the clamping assembly 15 drives the rotating basket 16 to rotate.

[0060] When rotating in the reverse direction, the rotating shaft 23 of the first drive assembly 20 drives the transmission component 14 to rotate in the reverse direction. The transmission component 14 drives the clamping assembly 15 to move away from the center of the rotating basket 16, thereby releasing the dishes to be washed that are clamped in the rotating basket 16.

[0061] like Figure 6 As shown, the first drive assembly includes a drive motor 21 and a rotating shaft 23, which are connected by a transmission mechanism.

[0062] In this embodiment, the first drive assembly further includes a mounting plate 22, wherein the mounting plate 22 is fixed to the outer bottom of the cleaning chamber 10 by bolts, the drive motor 21 is vertically mounted below the mounting plate 22 by bolts, the output shaft of the drive motor 21 passes through the mounting plate 22 and is fixedly connected to the lower end of the rotating shaft 23 by a coupling, the upper end of the rotating shaft 23 extends into the cleaning chamber 10 and is fixedly connected to the transmission component 14 of the dish basket assembly 11, so that when the drive motor 21 drives the rotating shaft 23 to rotate, it synchronously drives the dish basket assembly 11 to rotate in the cleaning chamber 10.

[0063] like Figure 9 As shown, in another embodiment, the transmission mechanism includes correspondingly arranged synchronous pulleys 24, and the two synchronous pulleys 24 are connected by a synchronous belt to realize the connection between the drive motor 21 and the rotating shaft 23.

[0064] In another embodiment, the transmission mechanism between the drive motor 21 and the rotating shaft 23 can also use a meshing gear pair to transmit power.

[0065] The drive motor 21 in this invention is an integrated geared motor with a built-in worm gear reducer. Its output shaft is inserted into the shaft hole at the tail end of the rotating shaft 23 to achieve a shaft connection (e.g., fixed by a key or pin). The upper end of the rotating shaft 23 extends into the cleaning chamber 10 and is fixedly connected to the transmission component 14 of the dish basket assembly 11, so that when the drive motor 21 drives the rotating shaft 23 to rotate, it synchronously drives the dish basket assembly 11 to rotate within the cleaning chamber 10.

[0066] The transmission mechanism between the drive motor 21 and the rotating shaft 23 can be implemented in various forms. For example, a coupling connection or a shaft-hole mating connection can be used (such as...). Figure 6 As shown), synchronous belt drive (such as...) Figure 9(As shown), gear pairs or worm gear reducers, etc. These transmission methods are all conventional techniques in this field, and those skilled in the art can choose the appropriate method according to actual needs.

[0067] like Figure 1 and Figure 4 As shown, the spray assembly 30 is used to spray high-pressure fan-shaped water jets onto the surface of the bowls for targeted rinsing. It includes at least one external spray head unit and at least one internal spray head unit, and adopts a layout design of "upper and lower opposite, inner and outer coverage".

[0068] In this embodiment, both the external nozzle unit and the internal nozzle unit are designed as a single unit, each including a nozzle mounting base and a nozzle. The nozzle mounting base includes an external nozzle mounting base and an internal nozzle mounting base, and the nozzle includes an external nozzle and an internal nozzle. Both the external nozzle mounting base and the internal nozzle mounting base are connected to the water supply assembly. The external nozzle is mounted on the external nozzle mounting base, and the internal nozzle is mounted on the internal nozzle mounting base. Both the external nozzle and the internal nozzle spray fan-shaped water streams.

[0069] Specifically, the external spray unit is installed on the top inner side of the washing chamber 10, above or to the side of the rotating basket 16. It sprays a fan-shaped water stream toward the outer surface of the bowl. It includes an external spray head mounting base 31 and an external spray head 32. The water inlet of the external spray head mounting base 31 is sealed to the external spray head water pipe 42 of the water supply assembly 40. The external spray head 32 is installed at an angle downward in the external spray head mounting base 31. The spray direction is toward the outer surface of the bowl carried on the bowl basket assembly 11. The fan-shaped water stream sprayed by the external spray head 32 is configured at an angle with the outer surface of the bowl to enhance the rinsing effect.

[0070] The inner nozzle unit is located below or to the side of the bowl basket assembly 11. It sprays a fan-shaped water stream toward the inner surface of the bowl. It includes an inner nozzle mounting base 33 and an inner nozzle 34. The water inlet of the inner nozzle mounting base 33 is sealed to the inner nozzle water pipe 43 of the water supply assembly 40. The inner nozzle 34 is installed in the inner nozzle mounting base 33 and sprays toward the inner surface of the bowl carried on the bowl basket assembly 11.

[0071] The external nozzle unit in this invention can be installed in the same swing-type installation method as the internal nozzle unit, or it can be fixedly installed in the cleaning chamber 10.

[0072] The water supply assembly 40 is used to provide a stable high-pressure water flow to the spray assembly 30. It specifically includes a solenoid valve (not shown in the figure) and a water supply pipeline. The solenoid valve is installed on the main line of the water supply pipeline and is used to control the on / off of the entire water supply pipeline to realize the start and stop control of the cleaning process. The water supply pipeline includes two branches: an external spray head water pipe 42 and an internal spray head water pipe 43. The external spray head water pipe 42 is sealed to the external spray head mounting base 31, and the internal spray head water pipe 43 is sealed to the internal spray head mounting base 33.

[0073] In another embodiment, the water supply assembly 40 may also selectively be equipped with a booster pump 41, wherein the booster pump 41 may be a low-noise plunger pump, the inlet of which is connected to the external water supply pipeline and the outlet is sealed to the main line of the water supply pipeline. The booster pump 41 can boost the water flow to a design threshold of not less than 0.6MPa, providing sufficient impact force for the fan-shaped water flow.

[0074] To achieve stable installation and rotation of the inner nozzle unit, the inner nozzle unit is connected to a fixed water supply passage through a rotary sealing assembly. The core function of the rotary sealing assembly is to allow the inner nozzle mounting base 33 to drive the inner nozzle 34 to rotate freely on the inner nozzle water pipe 43 to perform scanning motion, while preventing high-pressure water from leaking from the rotation joint. The water supply passage includes a connecting pipe section 47, which is connected to the inner nozzle water pipe 43. The rotary sealing assembly is located between the inner nozzle unit and the connecting pipe section 47.

[0075] In this embodiment, the connecting pipe section 47 and the inner nozzle water pipe 43 are integrally formed. The connection is fixed by tightening the locking nut 44 with the threaded engagement of the outer wall of the cleaning chamber 10. That is, the locking nut 44 fixes the connecting pipe section 47 to the wall of the cleaning chamber. The connecting pipe section 47 is made of metal (such as copper or 304 stainless steel).

[0076] It should be noted that the aforementioned fixed water supply passage is not limited to a single pipe component directly penetrating the chamber wall. In other embodiments of the present invention, the water supply passage may include a connecting base penetrating and fixed to the wall of the cleaning chamber 10; for example, a section of hollow metal pipe, or a pipe joint with a connecting flange, with the inner nozzle water pipe 43 then sealed to the connecting base. A rotary sealing assembly may also be disposed between the inner nozzle unit and the connecting base. This design also achieves the core architecture of a fixed water supply passage and a relatively rotatable sealing nozzle unit, and therefore should be considered an equivalent technical solution falling within the protection scope of the present invention.

[0077] The rotary sealing assembly includes a sealing plug 45 and a sealing ring 46 fitted onto the end of the connecting pipe section 47. The sealing ring 46 is located between the sealing plug 45 and the inner nozzle unit. The inner nozzle unit is threadedly engaged with the sealing plug 45 and tightened to axially compress the sealing ring 46, thereby forming a reliable radial rotary seal.

[0078] In this embodiment, the rotary sealing assembly uses a Step seal ring. It can be understood that the rotary sealing assembly is not limited to the threaded locking and compression sealing ring forms described above. For example, the fixing assembly can use flange bolt connections, quick-connect couplings, etc.; the sleeved rotary assembly can use mechanical seals, Glyd rings, or other mature rotary dynamic sealing forms. Any structure that can achieve water pipe fixing, nozzle rotation, and sealing function is within the protection scope of this invention.

[0079] The second drive assembly 50 is used to drive the inner nozzle unit to reciprocate and swing, so as to realize the water flow to scan and cover the inside of the bowl. It includes a power mechanism and a transmission conversion mechanism connected in sequence. The transmission conversion mechanism is connected to the inner nozzle unit. The power mechanism outputs power and transmits power through the transmission conversion mechanism to drive the inner nozzle unit to scan.

[0080] The second drive component 50 can be selectively connected to the first drive component 20, using the first drive component 20 as a power source for oscillating motion, or it can be a separate power source. In this embodiment, the second drive component 50 is selected to be connected to the first drive component 20 to convert the rotational power of the first drive component 20 into the reciprocating oscillating power of the nozzle. Alternatively, the second drive component 50 can be used as a power source, with the first drive component 20 obtaining driving force from the second drive component 50, i.e., the power source is set on the second drive component 50. In other embodiments of the present invention, the first drive component and the second drive component can also be provided with independent power sources.

[0081] In this invention, the power source of the second drive component 50 shares the power source of the first drive component 20, that is, the drive motor 21 is the power source of the entire mechanism.

[0082] like Figure 5 As shown, the specific structure is as follows: the power mechanism includes a main drive gear 510 and a driven gear 51. The main drive gear 510 is sleeved on the rotating shaft 23 and rotates synchronously with the rotating shaft 23. The driven gear 51 is rotatably mounted on the mounting plate 22 through a rotating shaft, and the gear part of the driven gear 51 meshes with the main drive gear 510 to realize the linkage between the first drive assembly 20 and the second drive assembly 50. That is, when the drive motor 21 drives the rotating shaft 23 to rotate, the driven gear 51 is driven to rotate through the meshing of the main drive gear 510 and the driven gear 51.

[0083] Specifically, the number of teeth of the main drive gear 510 is greater than the number of teeth of the driven gear 51 to achieve speed-increasing transmission, which causes the nozzle oscillation frequency to be higher than the rotation frequency of the bowl basket assembly 11. This enables the bowl basket assembly 11 to perform scanning coverage rinsing on the inner surface of the bowl within its spray range during the process of rotating the bowl basket assembly 11 several times or up to one revolution.

[0084] In another embodiment, a power source with a higher rotational speed than the first drive component 20 is independently set in the second drive component 50, so that the nozzle oscillation frequency is higher than the rotational frequency of the bowl assembly 11.

[0085] In another embodiment, the power mechanism can also use a synchronous belt to transmit power.

[0086] In this embodiment, the transmission gear 51 adopts an eccentric wheel structure to realize the reciprocating oscillation of the inner nozzle 34 driven by the transmission conversion mechanism.

[0087] The transmission mechanism includes a swing arm 52, a swing fork arm 53, a shaft hole support 54, and a swing arm shaft 55. One end of the driven gear 51 is fitted into the shaft hole on the mounting plate 22, and the other end is fitted into the shaft hole of the shaft hole support 54. Specifically, the driven gear 51 is provided with an eccentric wheel structure. The main drive gear 510 meshes with the driven gear 51. The eccentric wheel structure of the driven gear 51 fits into the elliptical groove on the swing arm 52. One end of the swing arm shaft 55 is fitted into the shaft hole on the mounting plate 22, and the other end is fitted into the shaft hole of the shaft hole support 54, so that the swing arm 52 can rotate around the swing arm shaft 55. When the main drive gear 510 rotates, it drives the eccentric wheel structure fixedly connected to the driven gear 51 to rotate synchronously, thereby driving the drive arm 52 to swing back and forth.

[0088] The swing fork arm 53 is fixed to one end of the swing arm 52 by a pin 531. The two ends of the swing fork arm 53 are provided with symmetrically arranged pins 531, and a limiting space 532 is formed between the two pins 531. The axis of the pin 531 is perpendicular to the swing plane of the swing arm 52, so that the swing fork arm 53 swings together with the swing arm 52, and the swing fork arm 53 can rotate relative to the swing arm 52 around the pin 531. The first-level power transmission of the transmission conversion mechanism is realized through the swing fork arm 53, which converts the rotational motion of the transmission gear 51 into the reciprocating swing motion of the swing fork arm 53.

[0089] The transmission conversion mechanism also includes a rocker arm 56, a connecting arm 57, a transmission shaft 58, and a bushing 561. The bushing 561 is sleeved on the rocker arm 56 and embedded in the limiting space 532 of the swing fork arm 53. When the swing fork arm 53 moves back and forth with the swing arm 52, it can drive the rocker arm 56 to swing back and forth. One end of the connecting arm 57 is fixedly connected to the rocker arm 56, and the other end is connected to the transmission shaft 58 through a flat key. The transmission shaft 58 passes through the mounting hole 12 at the bottom of the cleaning chamber 10 and is installed in conjunction with the mounting hole 12 through the bearing 59. The transmission shaft 58 is connected to the inner nozzle mounting seat 33 through a flat key, which can drive the inner nozzle mounting seat 33 and the inner nozzle 34 to swing back and forth, thereby realizing the two-stage power transmission of the transmission conversion mechanism, converting the reciprocating swing motion of the swing arm 52 into the reciprocating swing motion of the inner nozzle 34.

[0090] In this embodiment, the swing arm 52, swing fork arm 53, rocker arm 56, connecting arm 57 and transmission shaft 58 together constitute a transmission conversion mechanism of the present invention to drive the reciprocating swing motion of the inner nozzle unit.

[0091] The working process of this invention is as follows:

[0092] 1. Place the dishes to be washed without stacking them in the rotating basket 16, and close the lid of the washing chamber 10 to form a relatively sealed space in the washing chamber;

[0093] 2. Start the drive motor 21 and the booster pump 41. The drive motor 21 drives the rotating shaft 23 to rotate the rotating basket 16 at a constant speed. At the same time, the main transmission gear 510 drives the driven gear 51 to rotate synchronously.

[0094] 3. The transmission gear 51 drives the swing arm 52 to swing back and forth around the swing arm shaft 55 through the eccentric wheel structure. The swing fork arm 53 on the swing arm 52 drives the rocker arm 56 to swing through the limiting space 532. The rocker arm 56 drives the transmission shaft 58 to rotate back and forth through the connecting arm 57, thereby driving the inner nozzle mounting base 33 and the inner nozzle 34 to swing back and forth.

[0095] 4. The booster pump 41 pressurizes the water flow and delivers it to the outer nozzle 32 and the inner nozzle 34 through the outer nozzle water pipe 42 and the inner nozzle water pipe 43 respectively. The two nozzles spray out fan-shaped high-pressure water flow at the same time. The water flow from the outer nozzle 32 impacts the outer surface of the bowl, and the water flow from the inner nozzle 34 impacts the inner surface of the bowl.

[0096] 5. The uniform rotation of the rotating basket 16 and the reciprocating swing of the inner nozzle 34 work together to make the water curtain formed by the fan-shaped water flow contact the surface of the bowl at an angle, so as to achieve full coverage rinsing of the bowl surface. The wastewater generated during rinsing is directly discharged through the drain pipe connected to the drain port 13 on the side wall of the inner liner 18.

[0097] 6. After cleaning, turn off the drive motor 21 and the booster water pump 41, open the compartment cover and take out the dishes to complete the cleaning operation.

[0098] This invention uses a high-pressure fan-shaped water flow, combined with the coordinated movement of the rotating basket 16 and the swinging of the inner nozzle 34, to achieve thorough cleaning of the inner and outer surfaces of the bowls and utensils without dead angles. It can also quickly complete the cleaning process, significantly improving cleaning efficiency compared to existing technologies. Furthermore, it can quickly remove stubborn oil stains without the need for special detergents.

[0099] It should be noted that the order of the above steps is not strictly required and can be adjusted according to actual working conditions. For example, the booster pump can be turned on after the drive motor is started; or it can be turned on before the drive motor is started. As long as the dishes can be cleaned quickly, any adjustment to the order of steps should be considered an equivalent embodiment of the present invention.

[0100] Example 2

[0101] like Figures 10 to 15 As shown, this embodiment is based on the structure of embodiment one, but the structure of the second drive component, namely the nozzle scanning mechanism, is designed differently. Unlike embodiment one, which uses a reciprocating swing nozzle scanning method, this embodiment uses a rotary nozzle scanning method.

[0102] The transmission conversion mechanism in this embodiment includes a gear transmission group, which drives the power mechanism and the inner nozzle unit. The power mechanism drives the inner nozzle unit to rotate through the gear transmission group.

[0103] Specifically, the transmission conversion mechanism includes a primary power gear 511 and a secondary rotary gear 512. The primary power gear 511 and the driven gear 51 rotate synchronously through a key connection to realize the primary power transmission of the transmission conversion mechanism. The secondary rotary gear 512 meshes with the primary power gear 511 to realize the secondary power transmission of the transmission conversion mechanism. The secondary rotary gear 512 is threadedly connected to the inner nozzle mounting seat 33 in the inner nozzle unit through a sealing plug 45 and locked by a positioning screw to prevent the sealing plug from reversing and falling out, thereby driving the inner nozzle 34 to rotate.

[0104] The sealing plug 45 in this embodiment has a different structure from that in Embodiment 1. In this embodiment, the sealing plug can be fixed to the secondary rotating gear 512 using an integrated structure or a separate structure.

[0105] In this embodiment, the rotation axis of the inner nozzle mounting base 33 is inclined to the spray center line of the inner nozzle 34, so that a larger rinsing area can be achieved by rotating the inner nozzle 34 one revolution.

[0106] In this embodiment, the water supply passage is fixed differently from that in Embodiment 1. The connecting pipe section 47 is fixed to a bracket connected to the wall of the cleaning chamber 10, and this bracket serves as a fixing structure to securely install the water supply passage. Similarly, a rotary sealing assembly is disposed between the inner nozzle unit and the connecting pipe section 47 to achieve a rotary seal for the inner nozzle unit.

[0107] In this embodiment, the power relationship between the first drive component 20 and the second drive component 50 can also be that they share a power source or have an independent power source, and the specific method is the same as in Embodiment 1.

[0108] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
