Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 and 2, the embodiment provides an insecticidal sprayer capable of spraying upside down, which includes a bottle body 1 and a bottle cap 2, wherein the upper end of the bottle cap 2 is communicated with a spray head 3, the bottom end of the bottle cap is communicated with a spring cavity 4, the spring cavity 4 extends into the bottle body 1 and is communicated with a hose 5, the spray head 3 is connected with a piston rod 6, the piston rod 6 is placed in the spring cavity 4 and is abutted against a spring 7 in the spring cavity 4, the piston rod 6 is arranged in a through manner in the axial direction, when the spray head 3 is squeezed, the piston rod 6 pushes downwards to extrude air in the spring cavity 4 to form negative pressure, and insecticidal liquid is extracted upwards; after the single extraction is finished, the spring 7 urges the piston rod 6 to reset upwards.

The lateral wall of spring chamber 4 is equipped with slope 8, slope 8 is from last downward outwards protruding gradually, forms the upper surface 81 and the bottom surface 82 of slope down, the inside of slope 8 with spring chamber 4 is the intercommunication, slope upper surface 81 runs through and is equipped with a plurality of micropores 9, the lateral wall of spring chamber 4 is in the top position activity cover of slope 8 is equipped with tilt ring 10, tilt ring 10's internal surface is equipped with pearl 11. When the sprayer is upright, the inclined ring 10 is arranged on the upper surface 81 of the slope under the action of gravity, the beads 11 are abutted against the fine holes 9, so that the side wall of the spring cavity 4 is kept closed, and the spray head 3 sucks the insecticidal liquid at the end part of the hose 5 to realize the upright spraying; when the sprayer is turned upside down, the inclined ring 10 falls down, the beads 11 leave the fine holes 9, the insecticide liquid enters the spring cavity 4 through the fine holes 9, and the spray head 3 extracts the insecticide liquid at the bottle cap 2 to realize the upside-down spraying.

It should be noted that, when the sprayer is upright, the inclined ring 10 and the beads 11 are initially placed at the fine hole 9 by gravity, then with the extrusion of the nozzle 3, a negative pressure is formed inside the spring cavity 4, and at this time, the beads 11 are also tightly attached to the fine hole 9 by an inward suction force, so that the fine hole 9 is tightly blocked during the liquid suction process, and air leakage and liquid leakage due to the arrangement of the opening hole are avoided, that is, the structure of the embodiment does not affect the smooth operation of the upright spraying.

In this embodiment, the outer side wall of the spring cavity 4 is fixedly provided with a limiting block 12, the limiting block 12 is located between the bottle cap 2 and the inclined ring 10, and when the sprayer is tilted, the inclined ring 10 falls down and abuts against the limiting block 12. Thus, the stopper 12 functions to prevent the tilt ring 10 from falling excessively.

As can be seen from the above configuration, the beads 11 must be completely aligned with the fine holes 9 to achieve effective sealing, in order to ensure accurate pairing of the two, the outer side wall of the spring cavity 4 is provided with the guide ribs 13 along the axial direction, the inclined ring 10 is provided with the corresponding guide grooves 14 at the edge close to the spring cavity 4, by utilizing the sliding connection between the guide grooves 14 and the guide ribs 13, the inclined ring 10 can move back and forth along the guide ribs 13, and by virtue of the establishment direction of the guide ribs 13, the beads 11 and the fine holes 9 corresponding to the beads 11 can be always located on the same straight line, which is parallel to the guide ribs 13, that is, parallel to the axial line of the spring cavity 4, so that when the inclined ring 10 is established on the upper surface 81 of the slope, the beads 11 can be aligned with the fine holes 9 to achieve effective sealing.

Further, the fine holes 9 are uniformly arranged around the axis of the spring cavity 4, and the number of the fine holes 9 is more than two, so that the pesticide liquid on the upper section of the bottle body 1 can quickly enter the spring cavity 4 along the fine holes 9 when the sprayer is turned upside down. In the middle, the quantity and the position of the beads 11 correspond to the fine holes 9 one by one, so that the corresponding fine holes 9 can be sealed by the beads 11 when the sprayer is in an upright state, and the leakage hole is avoided.

Furthermore, the fine holes 9 are close to the bottle cap 2 to better guide the insecticide liquid at a lower liquid level, so as to avoid the retention and waste of the insecticide liquid.

In this embodiment, in order to increase the weight to block the fine pores 9, first, the beads 11 should be made of steel balls, which are heavier than conventional plastic particles, are not easily loosened due to buoyancy of the insecticide, and have a stronger adsorption degree after wetting; secondly, the diameter of the beads 11 must be larger than the pore size of the pores 9 to effectively seal them without sticking to the pore sites.

The inclined ring 10 is arranged inclined with respect to the side wall of the spring chamber 4, and the inclination angle of the inclined ring 10 is in accordance with the slope of the slope upper surface 81. The inclined ring 10 is similar to an umbrella shape or a bamboo hat shape, which is narrow at the top and wide at the bottom, and is easier to move downwards under the action of gravity, thus increasing the pressing strength of the beads 11 to the fine holes 9 to a certain extent.

Further, the circumferential width of the inclined ring 10 is greater than the width of the slope upper surface 81, and the water flow surging is reduced by the inclined ring 10, which also reduces the external impact on the beads 11.

In addition, the end of the spray head 3 is provided with the mist generator 15, because the insecticide in the upper section of the bottle body 1 enters the spring cavity 4 through the fine holes 9 when the sprayer is turned over, the mist generator 15 is arranged in the spray head 3 in the present embodiment, in addition to increasing the fine density of mist beads, more importantly, the mist generator 15 can isolate the insecticide with a slow flow rate to a certain extent, and prevent the insecticide from flowing out of the spray head 3 to form dropping liquid and being wetted to the external environment.

In summary, in the present embodiment, the fine hole 9 is formed through the side wall of the spring cavity 4, and the bead 11 and the inclined ring 10 are movably disposed outside the fine hole 9, when the sprayer is upright, the bead 11 is subject to the action of gravity to block the fine hole 9, so that the side wall of the spring cavity 4 is kept closed, when the sprayer head 3 is extruded, a negative pressure is formed in the spring cavity 4, and at this time, the bead 11 is not only subject to the gravity but also subject to an inward adsorption force to cling to the fine hole 9, so as to further avoid the air leakage phenomenon, and ensure that the liquid suction is smooth in the upright state; when the sprayer is turned upside down, the beads 11 fall toward the cap 2 so that the beads 11 leave the pores 9, and the insecticide liquid near the cap 2 enters the spring cavity 4 through the pores 9, so that the sprayer realizes the upside-down spraying.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
