For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] See also Figure 1 and Figure 2 The insect-proof pressing head of the embodiment of the utility model includes: a pressing head body 100, the pressing head body 100 is provided with a drainage channel 110, and a separate liquid outlet head 200 is installed at the end of the drainage channel 110. The liquid outlet head 200 is penetrated by a plurality of dispersed liquid outlet holes 201 connected to the drainage channel 110, and the minimum distance between any two points on the inner peripheral edge of the liquid outlet hole 201 is a, which satisfies 0.3mm≤a≤1mm.
[0030] The above-mentioned insect-proof pressing head has a liquid outlet head 200 at the end of the liquid discharge channel 110 of the pressing head body 100. The liquid outlet head 200 has a plurality of dispersed liquid outlet holes 201, and the minimum distance between any two points on the inner peripheral edge of the liquid outlet hole 201 is limited to between 0.3 mm and 1 mm, which not only ensures the function of fluid discharge, but also prevents mosquitoes from entering the bottle body through the liquid discharge channel 110, thereby ensuring the hygiene and safety of the product. It can be understood that after testing and inspection, common mosquitoes in life cannot pass through round holes of 1 mm and below. At the same time, in order to avoid the heavy pressing feel of pressing the pressing head body 100, it is found through testing that the aperture of the liquid outlet hole 201 is greater than 0.3 mm. The impact on the pressing feel is relatively small. It should be noted that the shape of the liquid outlet hole 201 is not limited, and it can be a round hole, an elliptical hole, a polygonal hole, a special-shaped hole, etc., as long as the minimum distance between any two points on the inner peripheral edge of the liquid outlet hole 201 is between 0.3 mm and 1 mm.
[0031] See also Figure 4 and Figure 5 In some embodiments of the present invention, the liquid outlet head 200 includes a cylindrical member 210, the interior of the cylindrical member 210 has a liquid outlet channel 230 with two ends connected therethrough, the interior of the cylindrical member 210 is provided with a partition member 220 for dividing the liquid outlet channel 230 into a liquid storage chamber 231 and a liquid outlet chamber 232, the liquid outlet hole 201 is opened on the partition member 220, the end of the cylindrical member 210 close to the liquid storage chamber 231 is butted with the end of the liquid discharge channel 110, and the cross-sectional area of the liquid storage chamber 231 adjacent to the partition member 220 is larger than the cross-sectional area of the end of the liquid discharge channel 110. It should be noted that when the fluid discharged from the liquid discharge channel 110 passes through the liquid outlet hole 201 on the partition member 220, it generally causes a sudden change in flow rate, which may make it difficult to squeeze out the fluid. When the liquid outlet head 200 of the above structure outputs fluid, the fluid discharged from the discharge channel 110 first enters the liquid storage chamber 231, and then passes through the liquid outlet hole 201 on the partition member 220 and is discharged from the liquid outlet chamber 232. The setting of the liquid storage chamber 231 can prevent the fluid from directly hitting the partition member 220 to form a backflow. In this embodiment, the cross-sectional area of the liquid storage chamber 231 is larger than the cross-sectional area of the discharge channel 110, which is conducive to increasing the size of the partition member 220 and setting more liquid outlet holes 201, and is also conducive to the fluid passing through the liquid outlet holes 201 more smoothly.
[0032] See also Figure 1In some embodiments of the present invention, the total area of all the liquid outlet holes 201 is greater than or equal to the minimum cross-sectional area of the liquid discharge channel 110 along its extension direction. Generally speaking, the beginning of the liquid discharge channel 110 is connected to the pump body of the pressing pump, and the end of the liquid discharge channel 110 is used to extrude the fluid. The cross-sectional area of the liquid discharge channel 110 gradually increases from the beginning to the end. When the total area of all the liquid outlet holes 201 is greater than or equal to the cross-sectional area of the beginning of the liquid discharge channel 110, the flow rate of the fluid extruded by a single press of the head body 100 can remain almost unchanged.
[0033] See also Figures 3 to 5 In some embodiments of the utility model, a plurality of needle-shaped strips 240 are scattered on the side wall of the partition member 220 away from the liquid discharge channel 110, and the needle-shaped strips 240 are extended along the length direction of the liquid outlet channel 230. The needle-shaped strips 240 are located between the liquid outlet holes 201 and are misaligned with the liquid outlet holes 201. It should be noted that the needle-shaped strips 240 extending outwards have a certain repelling effect on mosquitoes, and the needle-shaped strips 240 can have a certain warning effect on the vision and touch of mosquitoes to limit the number of mosquitoes moving near the liquid outlet hole 201. In addition, the misalignment of the needle-shaped strips 240 and the liquid outlet hole 201 can avoid further reducing the liquid flow rate of the liquid outlet hole 201.
[0034] See also Figure 3 and Figure 5 In some embodiments of the utility model, the end surface of the cylindrical member 210 away from the liquid discharge channel 110 is inclined upward from bottom to top in a direction away from the partition member 220, and the end of the needle-shaped strip member 240 away from the partition member 220 has a cone 241, and the tip of the cone 241 is inclined downward. The above-mentioned inclination angle formed on the end surface of the cylindrical member 210 is conducive to the more thorough discharge of the emulsion from the cylindrical member 210, reducing the problem of residual emulsion extruded, and the needle-shaped strip member 240 also has a drainage function. When the emulsion is discharged from the gap between the needle-shaped strip members 240, it will be discharged downward along the tip of the cone 241.
[0035] See also Figure 5 In some embodiments of the present invention, the plurality of needle-shaped strips 240 are arranged in multiple rows and columns, and the ends of the needle-shaped strips 240 do not protrude from the end surface of the cylindrical member 210 away from the liquid discharge channel 110. The plurality of needle-shaped strips 240 are arranged in multiple rows and columns to reduce the probability of mosquitoes moving to the liquid outlet 201; the ends of the needle-shaped strips 240 do not protrude from the cylindrical member 210 to avoid touching the user's skin and causing a tingling sensation, thereby avoiding a bad user experience.
[0036] In some embodiments of the utility model, in order to simplify the structure of the product, reduce processing costs, and avoid unnecessary assembly processes, the cylindrical member 210, the partition member 220, the liquid outlet 201, and the needle-shaped strip member 240 are an integrated plastic structure or an integrated rubber structure. It should be noted that the liquid outlet head 200 and the head body 100 are two independent components. By processing the liquid outlet head 200 separately, it is helpful to reduce the difficulty of production and processing. The liquid outlet head 200 is generally obtained by injection molding. The material can be selected from ordinary PVC, PC and other materials, or silicone can be selected to obtain better elasticity for easy installation.
[0037] See also Figure 2 , Figure 5 In some embodiments of the utility model, the upper side wall and the lower side wall of the liquid outlet head 200 are respectively protruded with a horizontal clamping strip 250, the head body 100 is provided with a mounting groove 120 matching the contour shape of the liquid outlet head 200, a through hole is provided at the bottom of the mounting groove 120 to communicate with the discharge channel 110, and the inner wall of the mounting groove 120 is provided with a strip groove 121 matching the clamping strip 250. In this embodiment, the clamping strip 250 and the liquid discharge head 200 are an integral structure obtained by injection molding, so the clamping strip 250 has a certain elastic deformation ability. When the liquid discharge head 200 is inserted along the depth direction of the mounting groove 120, the outer peripheral wall of the liquid discharge head 200 abuts against the inner peripheral wall of the mounting groove 120 to prevent the liquid discharge head 200 from moving relative to the head body 100. During this process, the clamping strip 250 is squeezed to undergo elastic deformation. When the clamping strip 250 enters the strip groove 121, the clamping strip 250 restores its elastic deformation to be clamped in the strip groove 121, thereby completing the assembly of the liquid discharge head 200, and the liquid discharge head 200 is not easy to fall off from the head body 100.
[0038] See also Figure 5 In some embodiments of the utility model, in order to facilitate the entry of the snap-in strip 250 into the strip groove 121, a guide slope 251 inclined backward is provided at the front end of the snap-in strip 250 in the direction pointing to the discharge channel 110. In order to prevent the snap-in strip 250 from being pulled out of the mounting groove 120, a vertical anti-detachment surface 252 is provided at the rear of the guide slope 251.
[0039] The utility model also discloses a pressing pump, including an insect-proof pressing head of any of the above technical solutions; the pressing pump is provided with a plurality of liquid outlet holes 201 of a certain size at the liquid outlet position, which not only ensures the function of fluid discharge, but also prevents mosquitoes from entering the bottle body through the liquid discharge channel 110, thereby ensuring the hygiene and safety of the product. Specifically, the minimum distance between any two points on the inner peripheral edge of the liquid outlet hole 201 is limited to between 0.3mm and 1mm. After testing and inspection, common mosquitoes in life cannot pass through a circular hole with a diameter of less than 1mm. Through testing, it is found that when the aperture of the liquid outlet hole 201 is greater than 0.3mm, the impact on the pressing feel is relatively small, thereby avoiding a heavy pressing feel of the pressing head body 100.
[0040] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
