Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to an integrated machine for transplanting and watering tobacco seedlings. Background Technology

[0002] During the transplanting of flue-cured tobacco, the soil at the bottom of the pre-dug seedling pits needs to be loosened with a small hoe. Then, each seedling is removed from the seedling tray and planted into the pit. Soil is then backfilled to cover the seedlings, and water is applied to ensure the tobacco plants survive and thrive. However, this method also presents some problems, such as low efficiency of manual transplanting, high risk of seedling damage, uneven watering, and wasted water resources.

[0003] Therefore, while some transplanters have been introduced to the market, current transplanters offer only a single transplanting method and cannot guarantee the integrity of seedlings during the transplanting process. Furthermore, they cannot effectively control watering after backfilling, leading to resource waste, reduced seedling survival rates, and negatively impacting tobacco growth. Additionally, current transplanters are relatively large and require auxiliary equipment, making them unsuitable for small-scale planting in the Yunnan, Guizhou, and Sichuan regions.

[0004] To address the problems of low transplanting efficiency, high risk of seedling damage, uneven watering, and water waste in the current technology for transplanting tobacco seedlings, it is necessary to optimize and improve the structure of the current transplanter in order to solve these technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an integrated watering machine for tobacco seedling transplanting, in order to solve the problems of low transplanting efficiency, high risk of seedling damage, uneven watering, and waste of water resources in the existing technology.

[0006] To achieve the above objectives, this utility model provides an integrated tobacco seedling transplanting and watering machine, comprising:

[0007] A pile tube having a central hole for tobacco seedlings to pass through, and a limiting platform provided on the outer wall of the pile tube;

[0008] A handle is provided on the pile tube;

[0009] A pressing handle is located below the holding handle. One end of the pressing handle is rotatably connected to the pile cylinder via a pin, and the other end is connected to the pile cylinder via a first spring. The connection point between the pin and the pile cylinder is spaced apart from the connection point between the first spring and the pile cylinder.

[0010] The claw-shaped flaps are configured in at least three and are rotatably connected to the ring seat;

[0011] The transmission component includes a sliding ring, a second spring, a first connecting rod, and a second connecting rod. The second spring and the sliding ring are both sleeved on the pile cylinder, and the second spring is positioned between the limiting platform and the sliding ring. The two ends of the first connecting rod are respectively connected to the pressing handle and the sliding ring. Multiple second connecting rods are configured to correspond one-to-one with the claw flaps, and the two ends of the second connecting rods are respectively connected to the sliding ring and the claw flaps.

[0012] A water injection component is connected to the pile cylinder. The inlet of the water injection component is connected to an external water source, and the outlet of the water injection component is equipped with a control valve, which is located above the claw flap. The valve core of the control valve is connected to the sliding ring through a connector.

[0013] When the press handle is pressed, the first connecting rod pushes the sliding ring to compress the second spring, causing the claw flaps to open. At the same time, the connecting member pushes the valve core of the control valve to open, allowing water to flow out from the outlet. When the press handle is released, the second spring drives the sliding ring to reset, causing the claw flaps to close. At the same time, the connecting member drives the valve core to close, sealing the water in the water injection component.

[0014] In one possible design, the water injection component includes a cylinder, a pouring pipe, and a ball valve. The upper end of the cylinder is equipped with the ball valve, and the lower end of the cylinder is connected to the pouring pipe. The diameter of the pouring pipe is smaller than the diameter of the cylinder. The control valve is located at the outlet of the cylinder, and the valve core of the control valve is connected to the connector via a valve stem. When the connector pushes the valve core upward, it enables the cylinder to connect to the pouring pipe. When the connector drives the valve core to reset, it enables the outlet of the cylinder to be blocked.

[0015] In one possible design, the lower end of the casting pipe is flat.

[0016] In one possible design, the cylinder is provided with a vent pipe, one end of which is provided with a filter cartridge that extends into the inner bore of the cylinder; the other end is connected to the atmosphere; the float of the ball valve is disposed in the vent pipe.

[0017] Specifically, when the control valve blocks the cylinder, the float rises and blocks the vent pipe; when the control valve opens the outlet, the float moves downward, allowing the cylinder to connect to the atmosphere through the vent pipe.

[0018] In one possible design, the water injection components are configured in at least two sets, and adjacent water injection components are connected by conduits.

[0019] In one possible design, a cushioning pad is fitted onto the handle.

[0020] In one possible design, the top of the pile tube is also provided with a guide plate, which is funnel-shaped.

[0021] In one possible design, the pile tube is provided with a positioning pile, and the positioning pile protrudes from the claw flap.

[0022] In one possible design, the positioning stake is detachably connected to the ring seat.

[0023] In one possible design, the connector is L-shaped, with its two ends connected to the control valve core and the sliding ring, respectively.

[0024] Through the aforementioned technical solutions, this integrated machine employs a mechanized claw-like structure, gently handling each tobacco seedling to ensure they are not subjected to additional pressure or damage during transplanting. This provides each seedling with an optimal starting point for growth, effectively reducing the risk of seedling damage associated with traditional transplanting. A control valve and sliding ring linkage mechanism enables precise and quantitative water supply, accurately providing the necessary moisture for each transplant, ensuring a humid environment for early seedling growth while conserving water resources, aligning with the concept of sustainable development in modern agriculture. This integrated machine combines soil loosening, planting, backfilling, and appropriate watering functions, significantly improving transplanting efficiency. The entire machine has a simple and compact structure, making it easy to carry, operate, and maintain. No complex training is required to master its use, making it suitable for farmers of different ages and skill levels. Furthermore, its lightweight design allows for easy transport to different plots, adapting to complex and varied terrain conditions, making it suitable for small-scale farmland in the Yunnan, Guizhou, and Sichuan regions.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that while the description of these embodiments is intended to aid in understanding the present invention, it does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0031] According to a specific embodiment of this utility model, an integrated machine for transplanting and watering tobacco seedlings is provided. Figures 1 to 3 One specific embodiment is shown.

[0032] See Figures 1 to 3 As shown, the integrated tobacco seedling transplanting and watering machine includes: a pile cylinder 1 with a central hole for the tobacco seedlings to pass through, and a limiting platform on the outer wall of the pile cylinder 1; a handle 2 disposed on the pile cylinder 1; a pressing handle 3 disposed below the handle 2, one end of the pressing handle 3 being rotatably connected to the pile cylinder 1 via a pin, and the other end being connected to the pile cylinder 1 via a first spring, wherein the connection point between the pin and the pile cylinder 1 and the connection point between the first spring and the pile cylinder 1 are spaced apart; claw flaps 4, configured with at least three, and rotatably connected to a ring seat 101; and a transmission component 5, including a sliding ring 51, a second spring 52, a first connecting rod 53, and a second connecting rod 54. The system includes a rod 54, in which the second spring 52 and the sliding ring 51 are both sleeved on the pile cylinder 1, and the second spring 52 is located between the limiting platform and the sliding ring 51; the two ends of the first connecting rod 53 are respectively connected to the pressing handle 3 and the sliding ring 51; the second connecting rod 54 is configured in multiple ways corresponding to the claw flaps 4; the two ends of the second connecting rod 54 are respectively connected to the sliding ring 51 and the claw flaps 4; and a water injection component 6 is connected to the pile cylinder 1. The inlet of the water injection component 6 is connected to an external water source, and the outlet of the water injection component 6 is equipped with a control valve, and the outlet is located above the claw flaps 4; the valve core of the control valve is connected to the sliding ring 51 through the connecting piece 8.

[0033] When the pressing handle 3 is pressed, the first connecting rod 53 pushes the sliding ring 51 to squeeze the second spring 52, causing the claw flap 4 to open. At the same time, the connecting piece 8 pushes the valve core of the control valve to open, allowing water to flow out from the outlet. When the pressing handle 3 is released, the second spring 52 drives the sliding ring 51 to reset, causing the claw flap 4 to close. At the same time, the connecting piece 8 drives the valve core to close, sealing the water in the water injection part 6.

[0034] The central hole of the seedling cylinder 1 allows the seedlings to pass through, ensuring they can smoothly enter the soil during transplanting. A limiting platform located on the outer cylinder wall provides positioning and support for the transmission component 5. A handle 2 is mounted on one side of the seedling cylinder 1, serving as the operator's grip. The connection point between the pin and the first spring is spaced, creating a lever effect when the handle 3 is pressed. The arrangement of at least three claw flaps 4 allows the seedlings to be effectively confined within their space when closed, and allows them to fall quickly and efficiently into the pre-designated seedling pit when the claw flaps 4 open.

[0035] A sliding ring 51 is mounted on the pile cylinder 1 and can slide on it. A second spring 52 is also mounted on the pile cylinder 1, located between the limiting platform and the sliding ring 51, and serves a resetting function. The two ends of the first connecting rod 53 are connected to the pressing handle 3 and the sliding ring 51 respectively, transmitting the action of the pressing handle 3 to the sliding ring 51. Second connecting rods 54 are arranged in a one-to-one correspondence with the claw flaps 4, with each second connecting rod 54 connected to the sliding ring 51 and the corresponding claw flap 4 respectively, enabling the sliding ring 51 to move and drive the claw flaps 4 to open and close.

[0036] Water inlet 6 connects to an external water source to provide a stable water supply. Furthermore, the outlet of the water inlet is equipped with a control valve, and the outlet is located above the claw flap 4, allowing water to flow out at appropriate times and be evenly sprayed onto the transplanting location. The valve core of the control valve is connected to the sliding ring 51 via a connector 8; when the sliding ring 51 moves, the control valve opens or closes accordingly.

[0037] The working process of the integrated tobacco seedling transplanter and watering machine is as follows: In the pre-transplanting state, the claw petals 4 are closed. At this time, the machine can be moved to the preset seedling pit, and the tobacco seedlings are placed into the pile cylinder 1 with the roots facing down and the leaves facing up, falling into the temporary storage space formed by the closed claw petals 4. Pressing the pressing handle 3 causes the sliding ring 51 to move upward through the first connecting rod 53, thereby compressing the second spring 52. Based on the movement of the sliding ring 51, the second connecting rod 54 moves upward, causing each claw petal 4 to open, allowing the tobacco seedling to detach from the temporary storage space of the claw petals 4 and fall into the seedling pit. At the same time, based on the action of the pressing handle 3, as the sliding ring 51 moves, the valve core of the control valve can be opened through the connecting piece 8, allowing water in the water injection piece 6 to flow out from the outlet for fixed-point and quantitative watering. After watering is completed, the all-in-one machine can be moved away and the pressure on the handle 3 can be released, so that the sliding ring 51 is reset under the action of the second spring 52. At this time, the claw flap 4 closes again; and the valve core in the water injection component 6 also closes the water outlet, stops the water flow, and ensures that the water is sealed in the water injection component 6, thus preparing for the next transplanting work.

[0038] Through the aforementioned technical solutions, this integrated machine adopts a mechanized claw-petal 4 structure, which gently handles each tobacco seedling, ensuring they are not subjected to additional pressure or damage during transplanting. This provides each seedling with an optimal starting point for growth, effectively reducing the risk of seedling damage associated with traditional transplanting. A linkage mechanism between the control valve and sliding ring 51 enables precise and quantitative water supply, accurately providing the necessary moisture at each transplanting stage, ensuring a moist environment for early seedling growth while conserving water resources, aligning with the concept of sustainable development in modern agriculture. This integrated machine combines soil loosening, planting, backfilling, and appropriate watering functions, significantly improving transplanting efficiency. The entire machine has a simple and compact structure, making it easy to carry, operate, and maintain. No complex training is required to master its use, making it suitable for farmers of different ages and skill levels. Furthermore, its lightweight design allows for easy transport to different plots, adapting to complex and varied terrain conditions, making it suitable for small-scale farmland in the Yunnan-Guizhou-Sichuan region.

[0039] In one embodiment provided in this disclosure, the water injection component 6 includes a cylinder 61, a pouring pipe 62, and a ball valve. The upper end of the cylinder 61 is provided with a ball valve, and the lower end of the cylinder 61 is connected to the pouring pipe 62. The diameter of the pouring pipe 62 is smaller than the diameter of the cylinder 61. A control valve is provided at the outlet of the cylinder 61, and the valve core of the control valve is connected to the connector 8 through the valve stem 7. When the connector 8 pushes the valve core upward, the cylinder 61 is connected to the pouring pipe 62. When the connector 8 drives the valve core to reset, the outlet of the cylinder 61 can be blocked.

[0040] The cylinder 61 serves as a water storage container, with a ball valve at its upper end and a connection to the pouring pipe 62 at its lower end. The pouring pipe 62, connected to the bottom of the cylinder 61, has a diameter smaller than that of the cylinder 61. This design helps ensure concentrated water flow and effectively directs water to the target location (such as the roots of tobacco seedlings). The ball valve, installed at the upper end of the cylinder 61, controls the fluid pressure within the cylinder 61. A control valve is located at the outlet of the cylinder 61. Since the valve stem 7 of the control valve is connected to the connecting piece 8, movement of the valve stem can move the valve core, thereby blocking and opening the outlet, and thus controlling the flow of water from the cylinder 61 to the pouring pipe 62.

[0041] Furthermore, the smaller diameter of the pouring pipe 62 allows the integrated machine to adapt more easily to different types of soil conditions, making it more flexible to use, especially for small-scale farmland in the Yunnan-Guizhou-Sichuan region, and reducing water waste.

[0042] In the initial state, the control valve is in the closed position, meaning the valve core blocks the outlet of cylinder 61, preventing water from flowing out. At this time, the ball valve is in the closed state, and there is a certain pressure inside cylinder 61, allowing water to flow into cylinder 61, but it will not be discharged through the pouring pipe 62.

[0043] When watering is needed, the operator can push the connector 8 to move the valve core upward, thereby opening the control valve. In this way, the water in the cylinder 61 can flow through the outlet into the watering pipe 62 and eventually reach its destination (e.g., the soil around the tobacco seedlings).

[0044] After watering is complete, release connector 8. The valve core of the control valve will automatically reset under the action of spring and / or gravity, re-sealing the outlet of cylinder 61 and preventing water from continuing to flow out. During this process, the remaining water in the pouring pipe 62 will also flow back into cylinder 61 due to gravity, avoiding waste.

[0045] The control valve design allows for precise water flow control, ensuring consistent and appropriate watering amounts for each irrigation, which helps water-sensitive crops like tobacco adapt better to transplanting environments. This device simplifies the irrigation process, reduces manual intervention, and improves work efficiency, especially in large-scale planting scenarios, saving significant time and labor costs. Precise water control effectively reduces water waste and lowers the risk of soil erosion and nutrient loss due to overwatering. The water injection unit 6 has a simple overall structure, is easy to assemble and disassemble, facilitates daily cleaning and maintenance, and also aids in troubleshooting and repair.

[0046] In one embodiment provided in this disclosure, the lower end of the irrigation pipe 62 is flattened. The flattened end helps to better disperse the water flow, allowing the water to penetrate evenly into the surrounding soil, rather than concentrating at a single point. This helps ensure that the soil around the roots of the tobacco seedlings is adequately moistened, promoting healthy seedling growth. Therefore, setting the lower end of the irrigation pipe 62 to be flat allows the water to act gently on the plant and the surrounding soil. Compared to a sharp end, the flattened design effectively reduces the risk of accidental damage to tobacco seedlings, especially important when operating near the root system. It is particularly suitable for small-area farmland in mountainous areas with complex terrain, such as Yunnan, Guizhou, and Sichuan, and has better adaptability.

[0047] Furthermore, the cylinder 61 is provided with a vent pipe 63, one end of which is equipped with a filter cartridge that extends into the inner hole of the cylinder 61; the other end is connected to the atmosphere. The float of the ball valve is disposed in the vent pipe 63 and is used to automatically adjust the opening and closing of the vent pipe 63 in response to changes in the liquid level inside the cylinder 61. Specifically, when the control valve blocks the cylinder 61, the float rises and blocks the vent pipe 63; when the control valve opens the outlet, the float moves downward, allowing the cylinder 61 to be connected to the atmosphere through the vent pipe 63.

[0048] When the control valve is closed, it can block the outlet of cylinder 61, preventing water from flowing out. In this situation, due to the high water level inside cylinder 61, the float will rise under the buoyancy of the water until it blocks the opening of the vent pipe 63, effectively preventing air from entering cylinder 61, maintaining stable internal pressure, and preventing accidental water leakage.

[0049] When the operator opens the control valve to clear the outlet, water begins to flow out of cylinder 61. As the water level drops, the float loses sufficient buoyancy and sinks, no longer blocking the vent pipe 63. At this time, the vent pipe 63 is connected to the atmosphere, allowing outside air to enter cylinder 61 to replenish the space, ensuring pressure balance inside and outside cylinder 61. This prevents water flow obstruction or cessation of water output due to internal vacuum, thus allowing water to flow out smoothly.

[0050] The float moves up and down with the water level, which can automatically adjust the opening and closing of the vent pipe 63, thereby ensuring that the water flow can be stable and continuous throughout the watering process, while also avoiding unnecessary waste of water resources.

[0051] The design of the float and vent pipe 63 allows for more precise control of the timing and amount of watering, reducing resource waste and poor crop growth caused by over- or under-watering. This not only reduces the need for manual intervention and improves work efficiency, but is also particularly suitable for large-scale planting scenarios. Furthermore, even and appropriate water supply helps protect newly transplanted tobacco seedlings and promotes their healthy and rapid growth.

[0052] In one embodiment, the water injection element 6 is configured in at least two groups, and adjacent water injection elements 6 are connected by a conduit 64, so that they can share a water source or operate synchronously.

[0053] When the control valve in a set of water injection components 6 is opened, water will not only flow out of that water injection component 6, but will also be transmitted to adjacent water injection components 6 through the conduit 64. This ensures that multiple locations receive a uniform water supply simultaneously, improving watering efficiency.

[0054] Each water inlet 6 retains independent operational capability, meaning that precise irrigation of localized areas can be achieved by individually controlling the control valve on each water inlet 6. This is particularly useful when different crops or different growth stages of the same crop have different water requirements.

[0055] Since all water inlets 6 are connected via conduits 64, the water pressure throughout the entire water supply system is relatively balanced. Even if the soil in one location is compacted or slightly blocked, it will not significantly affect the normal water outflow from other locations, ensuring the consistency of overall irrigation.

[0056] Based on the modular design of the water inlet unit 6, more water inlets 6 can be flexibly added as needed to cover a larger planting area. For small-scale farmland in the Yunnan-Guizhou-Sichuan region, the appropriate number and arrangement can be selected according to specific terrain conditions and crop layout to construct an optimized irrigation network.

[0057] Through the aforementioned technical solution, based on the design of multiple water inlets 6, irrigation can be carried out simultaneously over a wider area, reducing repetitive labor and improving work efficiency. Whether it's a large farm or a small, scattered plot of land, specific needs can be met by adjusting the number and arrangement of the water inlets 6, increasing the applicability and flexibility of this integrated machine. Despite having multiple water inlets 6, their collaborative operation simplifies the overall management and maintenance process. For example, adding a water source at just one point can provide service to all connected water inlets 6.

[0058] Furthermore, a cushioning pad is fitted onto the handle 2. One of the main functions of the cushioning pad is to improve the user's comfort when holding it. The soft and elastic material can reduce hand pressure and fatigue during prolonged use, especially in situations requiring frequent operation, such as the large-scale irrigation operation of tobacco transplanting as disclosed in this disclosure.

[0059] The cushioning pad is typically designed with textured or textured materials to increase friction, allowing users to grip the handle 2 more firmly and maintain good grip performance even in wet environments, reducing the risk of slippage. By improving the grip feel, operation becomes easier and more natural, reducing discomfort caused by prolonged work.

[0060] In one embodiment provided in this disclosure, a guide plate 9 is further provided at the top of the pile cylinder 1. The guide plate 9 is funnel-shaped. The funnel-shaped guide plate 9 has a large opening, which makes it easier for users to operate and makes it easier to add new tobacco seedlings into the pile cylinder 1, thereby improving the efficiency of tobacco seedling transplanting. At the same time, it can also reduce damage to the tobacco seedlings, thereby increasing the survival rate of the tobacco seedlings.

[0061] In this disclosure, a positioning stake 10 is provided on the pile cylinder 1, and the positioning stake 10 protrudes from the claw petal 4. Based on the setting of the positioning stake 10, it can help the user to accurately place the water injection component 6 in the predetermined position. By aligning the positioning stake 10 with a pre-marked point (e.g., the position of the tobacco seedling), it can be ensured that watering is carried out in the correct position each time, avoiding the problem of uneven irrigation caused by positional deviation.

[0062] In addition, the positioning stake 10 protruding from the claw-shaped petals 4 provides extra support when inserted into the soil, making the entire water injection component 6 more stable. Especially in soft or moist soil conditions, the positioning stake 10 can prevent the water injection component 6 from tilting or moving, ensuring the directionality and consistency of the water flow.

[0063] In this disclosure, the end of the positioning stake 10 is pointed. This design serves two purposes: when the water injection component 6 needs to be inserted into a deeper soil layer, the positioning stake 10 can also act as a guide, guiding the water injection component 6 along the correct path, reducing resistance and improving operational efficiency. This makes the water injection component 6 more stable during use, reducing the possibility of accidental displacement, which is especially important under complex terrain conditions.

[0064] Furthermore, the positioning stake 10 is detachably connected to the ring seat 101. Based on the detachable structure of the positioning stake 10 and the ring seat 101, users can easily install or remove the positioning stake 10 without tools. For example, a quick-release mechanism, such as a spring clip or rotation lock, can be used to make the operation simple and quick. This allows users to make flexible adjustments according to actual needs. Of course, users can also choose whether to install the positioning stake 10, as well as the specific number and location, based on different planting row spacings or specific location requirements.

[0065] When the positioning stake 10 wears or is damaged, a new part can be quickly replaced through the ring seat 101 without replacing the entire water injection system 6. In addition, the positioning stake 10 can be easily removed when the positioning function is not in use, reducing unnecessary volume and weight.

[0066] Specifically, the positioning pile 10 is connected to the ring seat 101 via a threaded connection structure.

[0067] In this disclosure, the connector 8 is L-shaped, with its two ends connected to the control valve core and the sliding ring 51, respectively. Based on the L-shaped structure of the connector 8, the movement from the movable handle to the sliding ring 51 and then to the control valve can be transmitted more directly and effectively. When the movable handle is pressed, the first connecting rod 53 pushes the sliding ring 51 upward, causing one end of the L-shaped connector 8 to rise, while the other end pulls the control valve core, opening it. This allows the movement of the sliding ring 51 and the control valve to be synchronized. When the claw flap 4 opens, the water injection component 6 begins to supply water; and when the movable handle is released, the claw flap 4 closes, and the control valve immediately closes, stopping the water supply.

[0068] The invention is implemented as follows: First, the water injection component 6 is connected to an external water source. Opening the operating valve allows the water source to continuously inject water into the cylinder 61. At this time, the pressing handle 3 is in the reset state, and the sliding ring 51 is reset under the action of the second spring 52. Simultaneously, under the action of the second spring 52, the second connecting rod 54 connected to the sliding ring 51 also moves the claw petal 4 and completes the closing action. When planting seedlings, hold the handle 2 with both hands or one hand, align the transplanter with the cultivation pit, insert the positioning stake 10 into the seedling pit, fix the positioning stake 10 on the sliding ring 51, straighten the transplanter, and place the flue-cured tobacco seedlings into the guide tray 9. The flue-cured tobacco seedlings slide down the guide cylinder 1 to the claw petal 4 and stop for planting. By gripping the handle 2 with both hands and pulling the pressing handle 3 upwards, the lever principle drives the first connecting rod 53 to move the sliding ring 51 upwards. The second connecting rod 54, under the action of the sliding ring 51, also pulls the claw flaps 4 upwards, causing them to open and push away the loose soil at the bottom of the seedling pit, thus helping the tobacco seedlings slide more easily into the pit. Simultaneously, since the sliding ring 51 is connected to the connecting piece 8, its displacement also drives the connecting piece 8 to move, indirectly allowing the valve core of the control valve to move relative to the water outlet, thus releasing water. When water flows into the seedling pit, it washes away the loose soil around the tobacco seedlings like quicksand, covering the roots. After watering, the user grips the handle 2 and lifts the machine upwards, completing the transplanting of the tobacco seedlings. At this point, releasing the pressing handle 3 causes the claw flaps 4 to close again under the action of the second spring 52, closing the water valve and stopping water overflow, thus saving water.

[0069] Finally, it should be noted that this utility model is not limited to the above-described optional embodiments, and anyone can derive other various forms of products under the guidance of this utility model. The above specific embodiments should not be construed as limiting the scope of protection of this utility model, which should be determined by the claims, and the description can be used to interpret the claims.
