Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, specifically to a top-sprayer. Background Technology

[0002] Aerosols are a common type of spray in our daily lives. Insecticides, air fresheners, various facial care sprays, and even paint sprayers all use the same aerosol valve for spraying. When in use, pressing the actuator squeezes the valve stem, allowing the liquid inside the can to be sprayed out along the nozzle. In home use, some young children lack safety awareness. Once a child comes into contact with these aerosols, they may easily press the actuator to spray the liquid. If the nozzle is pointed towards the child's face, the sprayed aerosol may directly hit the child's eyes or mouth. Since aerosols contain chemical components, direct contact with the eyes or accidental ingestion can easily harm a child's health, posing a significant safety hazard to the use of aerosols. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a top-spraying sprayer to solve the aforementioned technical problems.

[0004] This utility model embodiment adopts the following technical solution: a top-spray sprayer includes a valve seat cup, a valve device is disposed inside the valve seat cup, the valve stem of the valve device passes through the valve seat cup and extends upwards from the valve seat cup, a top-spray actuator is disposed at the upper end of the valve seat cup, the actuator clamp is inserted into the upper end of the valve stem, the actuator includes a cylindrical cover inserted into the valve stem, the upper edge of the cylindrical cover is located above the valve seat cup, a columnar spray head is disposed at the top of the cylindrical cover, a nozzle is disposed at the top of the spray head, and the upper edge of the cylindrical cover is positioned above the valve seat cup. The valve seat cup has outwardly extending pressing plates on both sides, with a movable gap between the pressing plates and the valve seat cup.

[0015] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-2As shown, this utility model embodiment provides a top-spray sprayer, including a valve seat cup 1, a valve device 2 disposed within the valve seat cup 1, a valve stem of the valve device 2 passing through the valve seat cup 1 and extending upwards from the valve seat cup 1, a top-spray actuator disposed at the upper end of the valve seat cup 1, the actuator clamp being inserted into the upper end of the valve stem, the valve stem being rotatably mounted within the housing of the valve device 2, and the actuator being connected to the top end of the valve stem, thus the actuator as a whole can rotate within the valve seat cup 1, the actuator including a cylindrical cover 3 inserted into the valve stem, the cylindrical cover 3 being rotatable within the valve seat cup 1, the upper edge of the cylindrical cover 3 being located above the valve seat cup 1, and a columnar part being disposed at the top of the cylindrical cover 3. The spray head 4 has a nozzle 5 on its top. The cylinder cover 3 has outwardly extending pressing plates 6 on both sides of its symmetrical upper edge. There is a movable gap between the pressing plates 6 and the valve seat cup 1. The valve seat cup 1 has upwardly protruding limiting blocks 7 on both sides of its symmetrical upper edge. The upper end of the limiting block 7 is located at the lower end of the pressing plate 6. The pressing plate 6 has a mounting plate 8 on its lower edge at the end away from the cylinder cover 3. The mounting plate 8 has an adjustable limiting pin 9. One end of the limiting pin 9 is located outside the mounting plate 8. The other end of the limiting pin 9 passes through the mounting plate 8 and extends to one side of the limiting block 7. The limiting block 7 has a limiting hole 7a at the position corresponding to the limiting pin 9.

[0018] The mounting plate 8 is provided with a pin hole, and the limiting pin 9 is inserted into the pin hole. The end of the limiting pin 9 that is inserted into the limiting block 7 is provided with a rectangular limiting piece 10. The limiting hole 7a is also a rectangular structure. The width of the limiting piece 10 is the same as the width of the limiting hole 7a, and the length of the limiting hole 7a is not less than the length of the limiting piece 10. The diameter of the limiting pin 9 is not greater than the width of the limiting piece 10.

[0019] A rubber ring 11 is provided inside the pin hole. The limiting pin 9 is inserted into the rubber ring 11 and its position can be adjusted within the rubber ring 11. The rubber ring 11 serves as a limit. The limiting pin 9 is clamped within the rubber ring 11 and can be inserted, removed, and rotated within the rubber ring 11.

[0020] The limiting pin 9 is located at one end outside the mounting plate 8 and has an adjusting rod head 12. The diameter of the adjusting rod head 12 is larger than the diameter of the limiting pin 9. The user can easily adjust the position of the limiting pin 9 by pinching the adjusting rod head 12.

[0021] The end faces of the limiting block 7 and the mounting plate 8 on opposite sides are both arc-shaped structures. This arrangement ensures that the two will not interfere with each other when the actuator rotates.

[0022] The upper edge of the limiting block 7 rests against the lower edge of the pressing plate 6.

[0023] The upper surface of the pressing plate 6 is provided with several anti-slip textures 13.

[0024] In use, the limiting pin 9 is first pulled out from the mounting plate 8, thus separating the limiting piece 10 at the end of the limiting pin 9 from the limiting block 7. Then, the actuator cap 3 is rotated, causing the pressing pieces 6 at both ends of the cap 3 to rotate to a position that avoids the limiting block 7. At this time, pressing the pressing pieces 6 on both sides of the cap 3 with your fingers can press the valve stem, causing the liquid in the tank to spray out through the nozzle 5 at the top of the actuator. After use, the cap 3 is rotated again, causing the mounting pieces 8 on the two pressing pieces 6 to rotate to the corresponding positions of the limiting block 7. Then, the limiting pin 9 is pushed towards one side of the limiting block 7, and the limiting piece 10 at the end of the limiting pin 9 moves along the limiting hole. Insert 7a through the limiting block 7, then rotate the limiting pin 9, causing the limiting piece 10 to rotate 90°. At this time, the limiting piece 10 is arranged perpendicularly to the limiting hole 7a. Since the length of the limiting piece 10 is greater than the width of the limiting hole 7a, the upper and lower ends of the rotating limiting piece 10 are attached to the inner wall of the limiting block 7, and the limiting pin 9 cannot be pulled out at the limiting block 7. Thus, the actuator cannot rotate. The limiting block 7 is located below the pressing piece 6. When the pressing piece 6 is pressed, the actuator cannot move downward due to the restriction of the limiting block 7. Therefore, the normal use of the spray can be restricted, avoiding safety hazards caused by misoperation.

[0025] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
