Description

Technical Field

[0001] The utility model relates to the field of pump suction and pressing nozzles, in particular to a fast pump suction component. Background Art

[0002] The push-type spray head is a common spraying device, usually used in push-type sprayers. It generates pressure by pressing to spray the fluid in the container in the form of a thin stream, mist or foam. This type of spray head has a simple design and is easy to operate. It is suitable for cleaning, disinfection, home gardening, spraying and many other occasions.

[0003] However, the pumping efficiency of the pumping assembly inside the existing nozzle is low. Since the sealing is not high enough during pumping, it is often necessary to press multiple times to pump the fluid into the nozzle and spray it out, especially near the nozzle. Since the nozzle is located at a higher position and is connected to the external atmosphere, the fluid needs to overcome greater gravitational potential energy, and the fluid at the nozzle is more likely to fall back. When pumping again, it is necessary to pump several times again before the fluid reaches the nozzle, which undoubtedly brings a bad user experience. Utility Model Content

When the pumping is finished, the first flow limiting member 105 will quickly abut against and seal the first flow limiting port 104 due to its own gravity and the reflux of part of the fluid, to prevent the fluid from flowing back from the first flow limiting port 104. A limiting member 106 is also provided on the first flow guide tube 102, and the first flow limiting member 105 is located between the limiting member 106 and the first flow limiting port 104 to prevent the first flow limiting member 105 from leaving the first flow limiting port 104 too far during pumping, and failing to fall back in time to seal the first flow limiting port 104. The pump pressure member 200 includes a piston head 201 and a second flow guide tube 202. A reset elastic member 203 is arranged between the piston head 201 and the bottom of the cylinder body 101. The piston head 201 moves as a piston in the cylinder body 101. The second flow guide tube 202 is connected to the nozzle 300, and a second flow limiting port 204 and a second flow limiting member 205 are arranged in the second flow guide tube 202. The second flow limiting member 205 can move away from the second flow limiting port 204 or fall back in time and abut against and seal the second flow limiting port 204 to prevent the fluid from flowing back from the second flow limiting port 204. An upper valve seat 400 is also arranged on the second flow guide tube 202. The second flow limiting member 205 is located between the upper valve seat 400 and the second flow limiting port 204 to prevent the second flow limiting member 205 from moving too far and failing to fall back in time to seal the second flow limiting port 204. The upper valve seat 400 is hollow and has an interference fit with the inner wall of the second flow guide tube 202. The upper end of the upper valve seat 400 is provided with a limit claw 401 and a third flow limiting port 402 extending toward the axis. A third flow limiting member 403 is accommodated between the limit claw 401 and the third flow limiting port 402. The third flow limiting member 403 moves between the limit claw 401 and the third flow limiting port 402 to open / seal the third flow limiting port 402. The pumping assembly can well ensure the efficiency of pumping by setting three flow limiting ports. The second flow guide tube 202 is connected to the nozzle 300.

When used next time, the fluid can be ejected from the nozzle 300 by pressing once. It is convenient and quick, and improves the user's comfort.

[0034] See also Figure 1 and Figure 2In the present embodiment, the first flow limiting opening 104 is in the shape of a truncated cone funnel with a small opening facing downward, the first flow limiting member 105 is in the shape of a sphere and is located above the first flow limiting opening 104, the diameter of the first flow limiting member 105 is larger than the diameter of the small opening of the first flow limiting opening 104, and the spherical first flow limiting member 105 can fit well and seal the truncated cone funnel-shaped first flow limiting opening 104 no matter from which direction it falls back, thereby increasing the sealing reliability.

[0035] More specifically, in the present embodiment, the position limiting member 106 is in the shape of a hollow tube, and the reset elastic member 203 is preferably a spring and is sleeved on the position limiting member 106 to prevent the reset elastic member 203 from being displaced when the pumping piston moves, thereby causing an unstable pumping structure; the side wall of the position limiting member 106 is provided with a plurality of first openings 107 extending to the bottom, and the fluid flows into the cylinder body 101 from the first flow guide pipe 102 through the first openings 107 to prevent the first flow limiting member 105 from fitting exactly to the bottom of the position limiting member 106 and causing blockage; the inner diameter of the bottom of the position limiting member 106 is smaller than the diameter of the first flow limiting member 105 to limit the movement of the first flow limiting member 105 between the bottom of the position limiting member 106 and the first flow limiting port 104, thereby preventing the first flow limiting member 105 from leaving the first flow limiting port 104 too far and failing to fall back in time to seal the first flow limiting port 104.

[0036] See also Figure 1 and Figure 2 In this embodiment, the second flow restriction opening 204 is in the shape of an inverted truncated cone funnel with a small opening facing upwards, so that when the pump sucks the fluid, the fluid flows from the large opening at the lower end of the second flow restriction opening 204 to the small opening at the upper end, and the impact force of the fluid is enhanced, thereby improving the efficiency of the fluid flowing upward through the second flow restriction opening 204; the second flow restriction member 205 is in the shape of a cone and is located above the second flow restriction opening 204, the diameter of the upper end of the cone is larger than the diameter of the small opening of the second flow restriction opening 204, and the inclined surface of the cone can fit with the second flow restriction opening 204 to seal the second flow restriction opening 204; at the same time, the second flow restriction member 205 is in the shape of a cone and is located above the second flow restriction opening 204, the diameter of the upper end of the cone is larger than the diameter of the small opening of the second flow restriction opening 204, and the inclined surface of the cone can fit with the second flow restriction opening 204 to seal the second flow restriction opening 204; A connecting rod 206 extends downward from the conical bottom of the component 205, and the other end of the connecting rod 206 is connected to a limiting head 207. The limiting head 207 is inserted into the limiting component 106 and can slide up and down along the limiting component 106 to limit the movement stroke of the second flow limiting component 205 and ensure that the conical inclined surface can always abut and seal the second flow limiting port 204 when the second flow limiting component 205 falls back; the connecting rod 206 connects the pump suction cylinder 100 and the pump pressure component 200, which further increases the stability of the pumping fluid when the pump pressure component 200 moves relative to the piston of the pump suction cylinder 100.

[0037] See also Figure 3In the present embodiment, the third flow limiting port 402 is in the shape of a truncated cone funnel with a small opening facing downward, the third flow limiting member 403 is in the shape of a spherical shape and is located above the third flow limiting port 402, and the diameter of the third flow limiting member 403 is larger than the diameter of the small opening of the third flow limiting port 402, so that no matter from which direction the third flow limiting member 403 falls back to the third flow limiting port 402, it can well fit and seal the third flow limiting port 402; at the same time, the side wall of the upper valve seat 400 is provided with a second opening 404 extending to the bottom, and the second opening 404 is located below the third flow limiting port 402, and the fluid can enter the upper valve seat 400 from the second opening 404 on the side wall of the upper valve seat 400 and then pass through the third flow limiting port 402, and does not necessarily have to enter the upper valve seat 400 only through the bottom of the upper valve seat 400, thereby preventing the second flow limiting member 205 from fitting exactly to the bottom of the upper valve seat 400 when ascending and causing blockage.

[0038] It should be noted that, in the present embodiment, the upper valve seat 400 is designed with higher precision, and the distance from the limit claw 401 to the third flow limiting port 402 is designed more finely, which can ensure that the fluid can quickly pass through the upper valve seat 400 and upward, and can also ensure that the third flow limiting member 403 can quickly fall back to the third flow limiting port 402 and completely seal the third flow limiting port 402; quickly cut off the connection between the pump suction component and the outside atmosphere, maintain the pressure difference, and make the suction and pumping speed faster and the effect more stable.

[0039] See also Figure 4 and Figure 5 A press spray nozzle, in this embodiment, the spray nozzle includes a gripping handle 500, a pressing plate 600 and the above-mentioned quick pumping assembly, the gripping handle 500 is snap-connected to the pumping cylinder 100, the pressing plate 600 is hinged to the gripping handle 500, and the bottom of the pressing plate 600 abuts against the top of the nozzle 300 to press the nozzle 300.

[0040] See also Figure 5 In this embodiment, the outer wall of the pump suction cylinder 100 is sleeved with a connection cover 700 to detachably connect the container bottle (not shown). The outer wall of the pump suction cylinder 100 is circumferentially provided with a clamping ring 108, and the connection cover 700 is snap-fitted on the clamping ring 108. The connection cover 700 can rotate relative to the pump suction cylinder 100 along the clamping ring 108.

[0041] It should be noted that, in the present embodiment, the container bottle maintains pressure balance with the outside atmosphere through the ventilation hole 103 on the pump suction assembly. When the pressure plate 600 is pressed or released, the pressure inside the pump suction assembly changes. When the pressure inside the pump suction assembly is lower than the outside pressure, a liquid suction action occurs, and the liquid is sucked from the container bottle into the pump suction cylinder 100 through the first flow limiting port 104; when the pressure inside the pump suction assembly is higher than the outside pressure, a liquid spraying action occurs, and the fluid is sprayed out from the nozzle 300 through the second flow limiting port 204 and the third flow limiting port 402.
