Description

Technical Field

[0001] This utility model belongs to the field of daily necessities technology, and specifically relates to a spray bottle body structure that integrates multi-specification nozzle adaptation, precise liquid dispensing, convenient mixing and medicine storage functions. It is suitable for scenarios such as home gardening plant care, indoor and outdoor cleaning, and small-scale farmland irrigation, and is especially suitable for fine maintenance operations with high requirements for the precision of medicine concentration control. Background Technology

[0002] Watering cans, as a common liquid spraying tool, are widely used for watering plants, foliar fertilization, cleaning, and dust removal. Traditional watering cans typically consist of a single cavity, a fixed nozzle, a simple handle, and a push-button pump, and have the following technical drawbacks: 1. Limited functionality and poor adaptability. Traditional spray bottle nozzles are often integrated into the bottle body or have a single threaded connection, making it impossible to change nozzles according to different spraying needs (such as mist, column, or water flow). This results in the same spray bottle only being able to meet a single usage scenario, increasing procurement costs.

[0003] 2. Insufficient liquid sampling accuracy leads to resource waste. Plant care requires precise control of nutrient solution or pesticide concentration. Traditional sprayers rely on subjective estimation by the user or additional measuring cups, resulting in large errors (usually ±10% or more). This can easily lead to excessively high pesticide concentrations that burn plants or excessively low concentrations that affect the effect, causing pesticide waste and environmental pollution.

[0004] 3. The mixing process is cumbersome and inefficient. Traditional spray bottles do not have a dedicated mixing mechanism. When adding pesticides or water, an external funnel is required, which is prone to spillage. Mixing pesticides and water requires manual shaking, which is uneven and time-consuming. Especially for high-viscosity pesticides (such as foliar fertilizers), sedimentation or stratification is likely to occur.

[0005] 4. Inconvenient storage and chaotic management of pesticides. Maintenance operations often require the use of multiple pesticides (such as insecticides, fungicides, and nutrient solutions). Traditional sprayers lack integrated storage structures, and pesticide bottles must be stored separately, making them prone to loss, confusion, or accidental spillage, especially inconvenient to carry when working outdoors.

[0006] 5. Poor sealing performance and high risk of liquid leakage. The detachable parts of traditional spray bottles (such as nozzles and straws) often use clearance fits or simple threaded connections. After long-term use, wear and tear can easily lead to seal failure, resulting in liquid leakage, affecting the user experience and creating safety hazards.

[0007] To address the aforementioned issues, while some improvements exist in the prior art (such as the "a spray bottle with replaceable nozzles" disclosed in patent CN202021234567.8), these only solve the problem of replacing a single nozzle and do not integrate functions for precise liquid dispensing, mixing, and storage. Patent CN202120876543.2 proposes a "spray bottle body with graduations," but the graduations are only used to roughly display the total capacity, which cannot achieve precise dispensing of the medicine and does not solve the problem of storing the medicine bottle.

[0008] Therefore, the present invention provides a spray bottle body structure that integrates multiple functions, which is the key to improving the practicality of the spray bottle. Summary of the Invention

[0009] The technical problem to be solved: To address the problems of limited functionality, low liquid dispensing accuracy, cumbersome mixing, and inconvenient storage in existing spray bottle technologies, this utility model provides a spray bottle that integrates four functions: multi-specification nozzle adaptation, precise liquid dispensing, convenient mixing, and medicine storage, achieving "one bottle for multiple uses" and improving operational efficiency and safety.

[0010] The technical solution of this invention is: a multi-functional spray bottle body, the structure of which includes a bottle body, a multi-specification adapter, a rubber bulb liquid dispensing tube, a slot assembly, a water inlet, and a funnel assembly, and the specific connection relationship of each component is as follows: 1. Bottle Body: Made of food-grade polypropylene (PP) injection molding, it can withstand the corrosion of acidic and alkaline agents with pH 2-12. After 24 hours of soaking, there is no cracking, discoloration or swelling. The overall shape is cylindrical, with a capacity of 1.5L, a height of 300mm, and a maximum diameter of 100mm. The outer side of the bottle body has longitudinal capacity scale lines (0-1500mL, minimum scale 50mL) for easy observation of the total liquid level. The bottom is equipped with a non-slip silicone pad (2mm thick) to prevent tipping. The top center has a cylindrical water outlet (outer diameter 20mm, height 15mm), and the outer surface of the water outlet has a threaded structure for installing adapters.

[0011] 2. Multi-specification adapter: Made of ABS engineering plastic injection molding, it can withstand the corrosion of acidic and alkaline agents with pH 2-12. After 24 hours of immersion, it shows no cracking, discoloration, or swelling. The overall shape is a stepped cylinder, 25mm high. The bottom has an internal thread interface (M20×1.5) that connects to the external thread of the bottle's outlet. The top has three sets of nozzle interfaces of different specifications along the axial direction. Specific parameters are as follows: Interface A: Internal thread M12×1.25, compatible with φ5mm mist nozzle (for foliar spraying); Interface B: Internal thread M10×1, compatible with φ8mm columnar nozzle (for root irrigation); Interface C: Internal thread M8×0.75, compatible with φ12mm water nozzle (for cleaning and rinsing); Each interface is equipped with a nitrile rubber sealing ring (1.5mm thick) on its inner wall, which is interference-fitted with the nozzle (0.2mm interference) to ensure a leak-free seal.

[0012] 3. Gel-ball dispensing tube: Consists of a gel-ball, a graduated pipette, and a one-way valve. Rubber ball: made of nitrile rubber, capacity 30mL, wall thickness 2mm, with a pressing surface (diameter 20mm) on the top for easy manual operation; Graduated pipette: made of transparent polyvinyl chloride (PVC), 250mm in length, 4mm in inner diameter, with graduations printed on the outer wall (0-30mL, minimum graduation 1mL), and a slanted cut (45°) at the bottom for easy insertion into the bottom of the medicine bottle to dispense liquid; One-way valve: Located at the connection between the pipette and the rubber bulb, it uses a silicone valve core (5mm in diameter) to achieve a precise liquid dispensing function of "squeezing the rubber bulb - releasing to draw in - one-way discharge"; The straw is connected to the bottle body through a fixing hole (4.2mm in diameter) on the side of the bottle. The hole wall and the straw are interference-fitted (0.1mm interference) to ensure a secure and sealed fit.

[0013] 4. Card slot assembly: Located on the side of the main body of the bottle, used to fix the medicine bottle. The card slot assembly is made of chemical corrosion resistant material and can withstand the corrosion of acid and alkali medicines with pH 2-12. After 24 hours of soaking, there is no cracking, discoloration or swelling. Each set of card slots includes: a PP retaining ring with a semi-open circular structure, 30mm in height, and inner diameters of 51mm (suitable for 50mL medicine bottles), 61mm (suitable for 100mL medicine bottles), and 71mm (suitable for 150mL medicine bottles). Elastic protrusions: Two silicone protrusions (2mm high, 3mm in diameter) are symmetrically arranged on the inner wall of the retaining ring, forming a small interference fit with the outer wall of the medicine bottle (interference amount 0.1-0.3mm), achieving the effect of "insertion to fix and easy removal"; Label slot: A rectangular groove (30mm long × 15mm wide) is provided on the outside of the retaining ring, which contains a replaceable paper label for marking the name and concentration of the medicine.

[0014] 5. Inlet and funnel assembly: Water inlet: Located on the upper part of the bottle body (50mm from the top), cylindrical in shape (20mm inner diameter, 10mm height), with external threads (M24×1.5) on the outer wall; Funnel: Made of transparent polycarbonate (PC), with an upper diameter of 60mm, a lower diameter of 20mm, and a height of 40mm. The inner wall of the lower opening is threaded (M24×1.5) to connect with the inlet thread. Wedge assembly structure: Three circumferentially evenly distributed wedge-shaped protrusions (5mm high, 15° inclination angle) are provided on the outer side of the lower opening of the funnel, and a wedge-shaped groove is provided at the corresponding position of the water inlet. When tightened, the protrusions are embedded into the groove to form a mechanical lock and prevent the funnel from loosening and falling off during use. Beneficial effects

[0015] The specific advantages of this invention are as follows: 1. Enhanced adaptability to multiple scenarios. With multiple adapters (3 types of interfaces), mist, column, and water jet nozzles can be quickly changed to suit various scenarios such as foliar spraying, root irrigation, and cleaning. This expands the applicability range by more than 3 times compared to traditional single-nozzle sprayers.

[0016] 2. Significantly improved liquid sampling accuracy. The gel ball sampling tube, combined with a one-way valve design, ensures a sampling error of ≤±0.5mL (compared to the traditional estimation error of ±5-10mL), guaranteeing precise control of pesticide concentration, avoiding plant burn or insufficient efficacy, and increasing pesticide utilization by 40%.

[0017] 3. Simplified preparation process. The integrated funnel assembly requires no additional tools, allowing for one-step water intake and chemical addition; the wide-mouth design of the funnel (60mm in diameter) reduces the risk of liquid spillage (the spillage rate is reduced from the traditional 15% to below 2%); and with the bottle's volume markings, it can be directly mixed according to the ratio (e.g., "10mL of chemical + 1000mL of water"), improving mixing efficiency by 60%.

[0018] 4. Convenient and safe medicine management. The card slot can fix medicine bottles of different sizes, and the label slot can be used to classify and store them, solving the traditional problem of "medicine bottles scattering"; the elastic protrusion with small interference fit design ensures that medicine bottles are stable and do not fall off (withstood a 1.5m drop test without loosening), while also facilitating quick and easy access.

[0019] 5. Enhanced sealing and durability. The interference fit (0.1-0.2mm) between the adapter, dispensing tube, and bottle body, along with the wedge-shaped assembly structure, ensures no leakage during long-term use (≥500 disassembly and assembly cycles). Key components are made of chemically resistant materials, which can withstand corrosion from common acid and alkali agents (pH 2-12), extending the service life to more than twice that of traditional spray bottles.

[0028] 3. Prepare the solution: Unscrew the funnel 2, insert the liquid collection tube 5 of the rubber ball into the water inlet, squeeze the top of the rubber ball 11 to inject 10mL of nutrient solution into the bottle 10, then add 1000mL of clean water through the funnel 2 (refer to the volume scale line), and tighten the funnel.

[0029] 4. Spraying procedure: Shake the bottle 10 times (approximately 2 rpm) to mix the solution evenly, press the spray bottle handle, and spray the leaves through the mist nozzle.

[0030] Scenario 2: Watering the roots of roses (requires a column nozzle + 20mL of pesticide) 1. Nozzle replacement: Unscrew the mist nozzle and screw the φ8mm cylindrical nozzle into interface B (M10×1) of the multi-specification adapter 1, ensuring a seal.

[0031] 2. Taking liquid from the medicine bottle: Take liquid from the 100mL medicine bottle, the operation is the same as in scenario 1, and the liquid volume is 20mL.

[0032] 3. Preparation and irrigation: Inject 20mL of pesticide and 1500mL of water (full capacity), mix them, and then slowly irrigate the roots through a columnar nozzle, using the concentrated water flow to penetrate the soil.

[0033] Scenario 3: Maintenance and Cleaning 1. Daily cleaning: After use, unscrew the funnel 2, pour in clean water through the side inlet 9, shake the bottle for 30 seconds, and then drain it from the adapter. Repeat 3 times to clean any residual medicine inside.

[0034] 2. Component replacement: If the sealing ring is aged (cracks appear or elasticity decreases), unscrew the multi-specification adapter 1, use needle-nose pliers to remove the old sealing ring, replace it with a new sealing ring (specification φ12mm×1.5mm) and reinstall.

[0035] In summary, this utility model, through its innovative design of multi-specification adapters, precise liquid dispensing tubes, integrated slots, and wedge-shaped funnels, effectively solves the problems of traditional sprayers' limited functionality and cumbersome operation, significantly improving the efficiency and precision of plant maintenance. It possesses high practical value and promising market prospects. This utility model is not limited to the specific embodiments described above.
