Description

Technical Field

[0001] This utility model belongs to the technical field of aerosol spraying equipment, and in particular relates to a novel spray cap for insecticidal aerosols. Background Technology

[0002] Since its invention in 1931, aerosol cans have been widely used by manufacturers, and the development of aerosol products has spanned nearly a century. With continuous iteration and upgrades, aerosol products have penetrated various industries. To date, thousands of products are packaged in aerosol cans—including hairspray, paint, pharmaceuticals, and more. In recent years, the development of aerosol products in the skincare industry has been particularly rapid. The aerosol spray cap is a crucial component of the aerosol can; pressing the cap at the top of the can sprays the product contained within as a mist.

[0003] As functional and aesthetically pleasing components, aerosol spray caps have increasingly higher requirements in terms of atomization effect, ease of use, transport strength and safety, and appearance. Existing aerosol spray caps have simple internal liquid channel structures, low liquid spraying rates, insufficient atomization fineness, and narrow spray coverage areas, which cannot achieve ideal insecticidal effects. Utility Model Content

[0004] To address the problems described in the background art, such as the simple internal liquid channel structure of the aerosol spray cap, low liquid spraying rate, insufficient atomization fineness, and narrow spray coverage area, which prevent the achievement of ideal insecticidal effects, this utility model proposes the following technical solution:

[0005] A novel spray cap for insecticidal aerosols, mounted on an aerosol bottle with a valve body, includes: a base, a pusher, and a nozzle; the end face of the base has a clearance hole; the side of the base has a discharge hole communicating with the clearance hole; the pusher has a coaxial and communicating liquid guiding channel and a liquid channel inside, the liquid guiding channel is inserted and connected to the valve body, and the liquid channel is perpendicularly connected to the nozzle; the fixed end of the pusher is fixedly connected to the inner wall of the discharge hole of the base through a fulcrum structure; when the movable end of the pusher is pressed, the pusher elastically presses down relative to the fulcrum structure, causing the liquid guiding channel to tightly insert into the valve body and push the valve body downward, driving the aerosol in the bottle to be drawn into the liquid channel; the variable diameter structure of the liquid channel increases the liquid flow rate, and the high-speed flowing liquid is broken and sheared by the nozzle, refined into narrow-diameter droplets and sprayed outward.

[0006] The base has multiple reinforcing ribs on its inner wall, each reinforcing rib being arranged at intervals along the circumference of the base and extending along the axial direction of the base.

[0007] Furthermore, the movable end of the press head is arc-shaped, and the height of the fixed end of the press head is greater than the height of the movable end of the press head.

[0008] Furthermore, the fulcrum structure includes a first part and a second part symmetrical about the centerline of the nozzle; the first part and the second part are respectively bent and extended to form an L-shaped structure.

[0009] Furthermore, in the longitudinal section of the liquid guiding channel, the inclination angles on both sides of the liquid guiding channel are equal, both being 30° to 60°.

[0010] Furthermore, in the longitudinal section of the liquid channel, the diameter of the liquid channel near the nozzle is smaller than the diameter of the liquid channel near the guide channel; the inclination angles on both sides of the liquid channel are equal, both being 80° to 88°.

[0011] Furthermore, the liquid channel is vertically connected to multiple nozzles, and each nozzle is connected to the others by a connecting piece. The diameter of each nozzle is 0.8mm to 1.2mm.

[0012] Furthermore, the diameter of the liquid guiding channel gradually increases from the side of the liquid guiding channel closer to the feed liquid channel towards the side of the liquid guiding channel closer to the valve body.

[0013] Beneficial effects: This utility model optimizes the internal structure of the liquid channel and nozzle inside the pump head by designing and improving the internal connection structure of the two, so that the aerosol can be quickly discharged through the liquid channel and nozzle after being drawn into the liquid channel and achieve a considerable coverage area.

Figure 2 This is a schematic cross-sectional view of the assembly structure of a novel spray cap and valve body for an insecticidal aerosol according to an embodiment of the present invention.

[0022] Reference Figure 1 A novel spray cap for an insecticidal aerosol according to an embodiment of the present invention includes: a base 1, a push-button 2, and a nozzle 3. The base 1 is detachably connected to the bottle body by pressing. The base 1 is generally cover-shaped, with a clearance hole 11 on one end face and a discharge hole 12 communicating with the clearance hole 11 on the side side. (Reference) Figure 2 The press head 2 has a liquid guiding channel 21 and a liquid material channel 22 inside. The liquid guiding channel 21 is inserted and connected to the valve body 5, and the liquid material channel 22 is vertically connected to the nozzle 3. The fixed end of the press head 2 is fixedly connected to the inner wall of the base outlet hole 12 through the fulcrum structure 4. The liquid guiding channel 21 is inserted and connected to the upper end of the valve body 5. One side of the movable end of the press head 2 is suspended in the outlet hole 12, thereby improving the elasticity of the press head 2 after being pressed, thus improving the elastic pressing effect of the press head 2. One end of the nozzle 3 extends out of the outlet hole 12, and the other end of the nozzle 3 is inserted and connected to the liquid material channel of the press head 2. When the movable end of the pusher 2 is pressed, the pusher 2 elastically presses down relative to the fulcrum structure 4, causing the liquid guiding channel 21 to be tightly inserted into the valve body 5 and pushing the valve body 5 downward, driving the aerosol in the bottle to be drawn into the liquid channel 22; the variable diameter structure of the liquid channel 22 increases the liquid flow rate, and the high-speed flowing liquid is broken and sheared by the nozzle 3, and refined into narrow-diameter droplets that are sprayed outward.

[0023] Figure 3 This is a cross-sectional structural diagram of a novel spray cap for an insecticidal aerosol according to an embodiment of the present invention. Figure 4 This is another cross-sectional structural schematic diagram of a novel spray cap for an insecticidal aerosol according to an embodiment of the present invention.

[0024] In practical application scenarios, please refer to the following: Figure 3 and Figure 4 When the user presses the nozzle 2, the nozzle 2 presses down relative to the fulcrum structure 4 to activate the valve body 5 of the aerosol. At this time, the distance between the power point of the user's hand and the fulcrum is greater than the resistance point of the valve body 5. Based on the lever principle, a mechanical structure is formed in which the power arm is greater than the resistance arm, thus achieving labor-saving operation, allowing the user to complete the pressing and activation with less force. The fulcrum structure 4 includes a first part 41 and a second part 42 symmetrically distributed about the center of the nozzle 3. Both the first part 41 and the second part 42 are curved and extended, thus forming an L-shaped structure. This L-shaped structure design allows the force to be distributed more evenly, avoiding stress concentration that could cause the fulcrum to deform and break. When the user releases the nozzle 2 and stops pressing, the "L"-shaped structure helps the valve body 5 to rebound and reset more quickly, ensuring the smoothness and continuity of the spray cap during use.

[0025] Figure 5 This is a bottom view of a novel spray cap for an insecticidal aerosol according to an embodiment of the present invention.

[0026] Specifically, refer to Figure 5 To enhance the overall support strength of the base 1, multiple reinforcing ribs 13 are arranged circumferentially along the inner wall of the base 1, with each rib extending axially along the base 1. The bottom of the base 1 is press-fitted to the bottle. The top of the base 1 has a certain curvature, forming a smooth arc surface that conforms to gripping habits. The movable end of the pump head 2 is concave and has corresponding rough texture to facilitate user pressing. Furthermore, the movable end of the pump head 2 is arc-shaped, and the height of the fixed end of the pump head 2 is greater than the height of the movable end. Under normal conditions, the movable end of the pump head 2 allows the user to easily achieve a spray effect by pressing the pump head 2.

[0027] Furthermore, to improve the fineness and coverage of the spray, in this embodiment, multiple nozzles 3 are fixedly provided on the end face of the fixed end of the nozzle 2. Each nozzle 3 has a diameter of 0.8 mm. In other embodiments, the diameter of each nozzle 3 is 1.2 mm. Additionally, the diameter of the liquid channel 22 near the nozzle 3 is smaller than the diameter of the liquid channel 22 near the inlet channel 21. During the intake of the aerosol, the pressure on the aerosol increases with the depth of entry into the liquid channel 22. Preferably, in this embodiment, the inclination angles on both sides of the liquid channel 22 are equal in the longitudinal section, and this inclination angle is 85°. In other embodiments, the inclination angle can also be 80°, 88°, or between 80° and 88°. The high-speed flowing liquid is broken and sheared by the nozzles 3, refined into narrow-diameter droplets and sprayed outwards. In other embodiments, the number of nozzles is 2-4; the length of each nozzle is 10mm-25mm; the diameter of each nozzle is 0.8mm-1.2mm; and the spacing between each nozzle is 4mm-8mm. The specific number can be selected according to actual needs.

[0028] In summary, this invention optimizes the internal structure of the liquid channel and the nozzle, and improves the internal connection structure of the two, so that the aerosol can be quickly discharged through the internal structure of the liquid channel and the nozzle after being drawn into the liquid channel, and achieve a considerable coverage area.
