Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a spraying device for cleaning agents. Background Technology

[0002] In the field of cleaning agent spray devices, spray devices are widely used in homes, industries, and commercial settings as a common tool. Their main function is to draw cleaning agent from a bottle through a suction tube and release it in spray form, thereby achieving uniform coverage and efficient cleaning of the target surface. However, existing cleaning agent spray devices have significant shortcomings, especially when large-area or long-term use is required. Users typically need to repeatedly squeeze the handle manually to maintain the spray. This operation is not only time-consuming and laborious but also easily leads to user fatigue, reducing convenience and efficiency. Furthermore, traditional spray device designs often lack automated or semi-automated operating mechanisms, failing to meet modern users' demands for efficient and labor-saving tools.

[0003] Meanwhile, existing spray devices also have certain limitations in their structural design. For example, the connection between the suction tube and the bottle may not be secure enough, easily leading to loosening or leakage due to frequent use; the design of the nozzle and spray head may also affect the uniformity and coverage of the spray, thus reducing the cleaning effect. These problems make it difficult for existing spray devices to fully meet user needs in practical applications. Therefore, developing a cleaning agent spray device that can reduce manual operation burden, improve spray efficiency, and optimize the user experience has become an urgent technical challenge to be solved in this field. Utility Model Content

[0004] The purpose of this invention is to provide a spraying device for cleaning agents to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray device for cleaning agents, comprising a bottle body, a cap, a fixing cylinder, a spray head, a nozzle, a suction assembly, and an optional automatic control mechanism. The bottle body is a container for holding the cleaning agent, and its upper part has an external thread structure that connects with the cap threadedly, ensuring that the cleaning agent does not leak during storage and use. Furthermore, a fixing cylinder is provided inside the cap; the lower end of the fixing cylinder is fixed to the inner wall of the cap by a snap-fit ​​or interference fit, while the upper end supports and connects to the spray head, ensuring the spray head remains stable during use.

[0006] The nozzle is mounted on the top of the fixed cylinder and contains multiple functional components to adjust the spray volume and spray angle. Inside the nozzle is a connecting sleeve, the outer wall of which is threaded into the inner wall of the fixed cylinder, securely mounting the nozzle to the cylinder. The inner wall of the connecting sleeve has an annular groove to accommodate a contact block, which is held in a preset position by pressure applied by an elastic element, serving as a limit. Furthermore, the nozzle also contains a sliding cylinder with a groove on its inner wall. The groove has a trapezoidal cross-sectional shape, and its width gradually changes along the axial direction of the cylinder, allowing for precise adjustment of the spray volume. A rotating ring is located outside the sliding cylinder; rotating the ring moves the cylinder along the groove, thus changing the spray volume. Notably, the bottom of the groove has a chamfered slope to reduce frictional resistance during movement and improve operational smoothness.

[0007] The nozzle is connected below the spray head and has an internal flow channel. The outlet shape of the flow channel can be designed as circular, fan-shaped, or other specific geometric shapes to control the spray direction and pattern of the cleaning agent. Furthermore, the nozzle's flow channel inlet has a guide ramp with an angle ranging from 30° to 60° to guide the cleaning agent smoothly into the flow channel, avoiding uneven spraying caused by liquid impact. In addition, the nozzle and spray head are connected by a slot with a depth of 1mm to 3mm to ensure that the nozzle will not loosen or fall off during use.

[0008] The extraction assembly includes an extraction tube, one end of which extends to the bottom of the bottle, and the other end is connected to the nozzle via a sealing ring, ensuring a stable delivery of cleaning agent from the bottle to the nozzle. The extraction tube is made of corrosion-resistant materials, such as polypropylene or stainless steel, to accommodate different types of cleaning agents. Furthermore, the inner diameter of the extraction tube ranges from 2mm to 5mm, and the outer diameter ranges from 4mm to 7mm, to ensure the cleaning agent flow rate meets spray requirements.

[0009] To further enhance ease of use, this invention may also include an automatic control mechanism, comprising a push-button trigger and a rotary adjuster. The push-button trigger utilizes a lever principle to achieve continuous spraying of the cleaning agent; the user only needs to press once to activate the spray function, eliminating the need for continuous manual operation. The rotary adjuster is located outside the nozzle; rotating the adjuster changes the opening of the internal channel, thereby achieving stepless adjustment of the spray volume. Specifically, the automatic control mechanism incorporates a spring with an elastic coefficient ranging from 5 N / mm to 15 N / mm to provide a restoring force, ensuring that the trigger quickly returns to its initial state after release.

[0010] This invention achieves flexible adjustment of spray volume and spray angle through optimized design of the nozzle's internal structure. Specifically, the cooperation between the slide cylinder and the slide groove allows for more precise adjustment of the spray volume, while the introduction of the rotating ring simplifies the user's operation. The nozzle design further enhances the stability of the spray effect, and the guide slope effectively reduces the impact of liquid impact on spray uniformity. The rational layout of the suction component ensures a stable supply of cleaning agent, preventing spray interruptions due to insufficient liquid supply.

[0011] In the above technical solution, this utility model provides a spray device for cleaning agents, which has the following beneficial effects: First, by optimizing the internal structure of the nozzle, users can easily adjust the spray volume and spray angle to meet the needs of different scenarios. Second, the rational design of the suction component ensures that the cleaning agent can be stably delivered from the bottle to the nozzle, avoiding spray interruption due to insufficient liquid supply. Third, the optional automatic control mechanism reduces the frequency of manual operation, making it particularly suitable for scenarios involving large-area or long-term use of cleaning agents. Finally, the threaded connection between the cap and the bottle body, as well as the design of the internal fixing cylinder, effectively improves the sealing performance of the device, preventing cleaning agent leakage.

[0012] In particular, this invention reduces frictional resistance between components and improves the overall structural reliability through the design of chamfered and guide bevels. The slot design further enhances the connection stability between components, preventing loosening or displacement. The layout of each component is compact and reasonable, and the overall device is small in size, making it easy to carry and store.

[0013] In summary, this utility model, through innovative structural design and functional optimization, significantly improves upon the shortcomings of existing spray devices, providing users with a more efficient, convenient, and reliable cleaning agent spray solution.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Please see Figure 1-5 This utility model provides a spray device for cleaning agents, including a bottle body 1, a bottle cap 2, a fixing cylinder 3, a spray head 4, a nozzle 5, a suction assembly 7, and an optional automatic control mechanism. The bottle body 1, a container for holding the cleaning agent, is made of corrosion-resistant materials such as polypropylene or stainless steel to accommodate different types of cleaning agents. The upper part of the bottle body 1 has an external thread structure, and the inner side of the bottle cap 2 has a corresponding internal thread structure; the two are connected by threads to ensure that the cleaning agent does not leak during storage and use. The inner side of the bottle cap 2 also has a fixing cylinder 3; the lower end of the fixing cylinder 3 is fixed to the inner wall of the bottle cap 2 by snap-fit ​​or interference fit, while the upper end is used to support and connect the spray head 4, ensuring that the spray head 4 remains stable during use.

[0019] The nozzle 4 is mounted on top of the fixed cylinder 3 and contains multiple functional components to adjust the spray volume and spray angle. A connecting sleeve 601 is located inside the nozzle 4. The outer wall of the connecting sleeve 601 is threadedly connected to the inner wall of the fixed cylinder 3, thus securely mounting the nozzle 4 onto the fixed cylinder 3. The inner wall of the connecting sleeve 601 has an annular groove to accommodate the abutment block 602. The abutment block 602 is held in a preset position by pressure applied by the elastic element 606, serving as a limit. A sliding cylinder 603 is located inside the nozzle 4. A sliding groove 604 is formed on the inner wall of the sliding cylinder 603. The cross-sectional shape of the sliding groove 604 is trapezoidal, and its width gradually changes along the axial direction of the sliding cylinder 603, thereby achieving precise adjustment of the spray volume. A rotating ring 605 is located outside the sliding cylinder 603. Rotating the rotating ring 605 moves the sliding cylinder 603 along the sliding groove 604, changing the spray volume. The bottom of the sliding groove 604 has a chamfered bevel 609 to reduce frictional resistance during the movement of the sliding cylinder 603, improving operational smoothness.

[0020] Nozzle 5 is connected below nozzle 4 and has an internal flow channel. The outlet shape of the flow channel can be designed as a circular, fan-shaped, or other specific geometric shape to control the spray direction and pattern of the cleaning agent. A guide ramp 611 is provided at the inlet of the flow channel of nozzle 5. The angle of guide ramp 611 ranges from 30° to 60° to guide the cleaning agent smoothly into the flow channel and avoid uneven spraying caused by liquid impact. Nozzle 5 is connected to nozzle 4 by a slot 610 with a depth of 1mm to 3mm to ensure that nozzle 5 will not loosen or fall off during use.

[0021] The extraction assembly 7 includes an extraction tube 71. One end of the extraction tube 71 extends to the bottom of the bottle 1, and the other end is connected to the nozzle 4 via a sealing ring, ensuring that the cleaning agent can be stably delivered from the bottle 1 to the nozzle 4. The extraction tube 71 is made of corrosion-resistant materials such as polypropylene or stainless steel, with an inner diameter ranging from 2mm to 5mm and an outer diameter ranging from 4mm to 7mm, ensuring that the flow rate of the cleaning agent meets the spray requirements. The length of the extraction tube 71 is adjusted according to the height of the bottle 1 to ensure that it can reach the lowest level of the cleaning agent inside the bottle 1.

[0022] To further improve ease of use, this invention can also be equipped with an automatic control mechanism, which includes a push-button trigger and a rotary adjuster. The push-button trigger uses a lever principle to achieve continuous spraying of the cleaning agent; the user only needs to press once to start the spraying function without continuous manual operation. The rotary adjuster is located outside the nozzle 4; rotating the adjuster changes the opening of the internal channel, thereby achieving stepless adjustment of the spray volume. The automatic control mechanism contains a spring with an elastic coefficient ranging from 5 N / mm to 15 N / mm to provide a reset force, ensuring that the trigger can quickly return to its initial state after release.

[0023] In actual use, the user first pours the cleaning agent into bottle 1 and tightens the cap 2 to ensure a tight fit between bottle 1 and cap 2. At this time, the fixing cylinder 3 firmly fixes the nozzle 4 to the cap 2, while one end of the suction tube 71 is immersed in the cleaning agent, and the other end is connected to the nozzle 4 through a sealing ring to form a complete liquid delivery channel. When spraying is required, the user rotates the rotating ring 605 to move the slide cylinder 603 along the slide groove 604 to adjust the spray volume. The trapezoidal cross-section design of the slide groove 604 makes the movement range of the slide cylinder 603 linearly related to the spray volume, which the user can adjust flexibly according to needs. The chamfered bevel 609 design reduces the frictional resistance of the slide cylinder 603 during movement, improving the smoothness of operation.

[0024] The design of nozzle 5 further enhances the stability of the spray effect. The guide bevel 611, with an angle range of 30° to 60°, guides the cleaning agent smoothly into the flow channel, avoiding uneven spraying caused by liquid impact. The groove 610 between nozzle 5 and spray head 4 has a depth of 1mm to 3mm, ensuring that nozzle 5 will not loosen or fall off during use. In addition, the flow channel outlet shape of nozzle 5 can be designed as a circular fan shape or other specific geometric shapes to meet the spraying needs of different scenarios. For example, when cleaning a large flat surface, a fan-shaped nozzle can be selected to cover a larger area; when cleaning a small space, a circular nozzle can be selected for concentrated spraying.

[0025] The introduction of an automatic control mechanism significantly improves ease of use. Users can activate the spray function simply by pressing the push-button trigger, eliminating the need for continuous manual operation. The push-button trigger uses a lever principle to convert pressing force into a continuous spray of cleaning agent, suitable for long-term or large-area cleaning tasks. A rotary adjuster located externally on the nozzle 4 allows users to steplessly adjust the spray volume by changing the opening of the internal channel. The spring's elastic coefficient ranges from 5 N / mm to 15 N / mm, providing sufficient reset force to ensure the trigger quickly returns to its initial state after release, preventing liquid leakage due to delayed reset.

[0026] In practical applications, this spray device is suitable for various scenarios, including household cleaning, industrial cleaning, and public place cleaning. For example, in household cleaning, users can fill the bottle 1 with cleaning agent and select a suitable spray mode by adjusting the flow channel outlet shape of the nozzle 5 to clean different surfaces such as kitchen range hoods, bathroom glass, or floors. In industrial cleaning, the device's large-area spraying function effectively improves cleaning efficiency and reduces the burden of manual operation. In public place cleaning, the continuous spraying function of the automatic control mechanism makes cleaning work more efficient, especially suitable for places requiring frequent cleaning, such as large shopping malls, airports, and train stations.

[0027] The technical solution of this utility model achieves flexible adjustment of spray volume and spray angle through optimized design of the internal structure of the nozzle 4. The cooperation between the slide cylinder 603 and the slide groove 604 makes the adjustment of spray volume more precise, while the introduction of the rotating ring 605 simplifies the user's operation steps. The design of the nozzle 5 further improves the stability of the spray effect, and the setting of the guide slope 611 effectively reduces the impact of liquid impact on spray uniformity. The reasonable layout of the suction component 7 ensures a stable supply of cleaning agent and avoids spray interruption due to insufficient liquid supply.

[0028] The advantages of this invention are as follows: First, by optimizing the internal structure design of the nozzle 4, users can easily adjust the spray volume and spray angle to meet the needs of different scenarios. Second, the reasonable design of the suction component 7 ensures that the cleaning agent can be stably delivered from the bottle 1 to the nozzle 5, avoiding spray interruption due to insufficient liquid supply. Third, the optional automatic control mechanism reduces the frequency of manual operation, making it particularly suitable for scenarios involving large-area or long-term use of cleaning agents. Finally, the threaded connection between the cap 2 and the bottle 1, as well as the design of the internal fixing cylinder 3, effectively improves the sealing performance of the device and prevents cleaning agent leakage.

[0029] In particular, this invention reduces frictional resistance between components and improves the overall structural reliability through the design of the chamfered bevel 609 and the guide bevel 611. The slot 610 further enhances the connection stability between components and prevents loosening or displacement. The compact and reasonable layout of each component makes the overall device small in size, easy to carry and store.

[0030] In summary, this utility model significantly improves upon the shortcomings of existing spray devices through innovative structural design and functional optimization, providing users with a more efficient, convenient, and reliable cleaning agent spray solution.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
