[0002] With the rapid development of people's lives, lotion spray nozzles are becoming more and more widely used in the cosmetics industry. Currently, bottles containing cosmetics or daily necessities all use spray nozzles to squeeze out lotion, which is not only convenient but also brings convenience to people to a certain extent.

[0003] Existing emulsion nozzles cannot control the amount of emulsion dispensed during use, which can easily lead to excessive emulsion being squeezed out with a single press, resulting in waste. Furthermore, the pressing part of most emulsion nozzles is located at the top of the nozzle, requiring the user to apply significant pressure to dispense emulsion, making the emulsion nozzle inconvenient to use. To address this issue, we propose a vacuum constant pressure emulsion nozzle. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum constant pressure emulsion nozzle to solve the problems mentioned in the background art, such as the inability to control the amount of emulsion input during use, which easily leads to excessive emulsion being squeezed out during a single press, resulting in emulsion waste. Furthermore, the pressing part of a typical emulsion nozzle is located at the top of the nozzle, requiring the user to apply considerable pressure to obtain emulsion, thus making the emulsion nozzle inconvenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum constant pressure emulsion nozzle, comprising a connecting box and a mounting cover, wherein the mounting cover is fixedly connected to the top of the connecting box, a lead screw is rotatably connected to the bottom left side of the inner cavity of the connecting box, a first bevel gear is fixedly connected to the lower side of the outer side wall of the lead screw, a baffle is screwed to the upper side of the outer side wall of the lead screw, a rotating shaft is rotatably connected to the left side wall of the connecting box, the right end of the rotating shaft passes through the connecting box and extends into the inner cavity of the connecting box, and a second bevel gear is fixedly connected to the right end of the rotating shaft, the second bevel gear meshing with the first bevel gear and rotating, a knob is fixedly connected to the left end of the rotating shaft, a limiting groove is formed on the left side wall of the inner cavity of the connecting box, a limiting block is slidably connected to the inner cavity of the limiting groove, and the limiting block is fixedly connected to the left side wall of the baffle.

[0006] As a further description of the above technical solution:

[0007] A bottle cap is fixedly connected to the bottom of the connecting box, and the inner wall of the bottle cap is provided with internal threads.

[0008] As a further description of the above technical solution:

[0009] The top of the inner cavity of the bottle cap is fixedly connected to a nozzle body, and the bottom of the nozzle body is fixedly connected to a straw.

[0010] As a further description of the above technical solution:

[0011] A pressing head is slidably connected to the top of the connecting box, and a liquid outlet is fixedly connected to the right side wall of the pressing head. The liquid outlet is connected to the nozzle body.

[0012] As a further description of the above technical solution:

[0013] A sleeve is rotatably connected to the right side wall of the inner cavity of the mounting cover, and a semi-circular pressure block is fixedly connected to the bottom of the sleeve.

[0014] As a further description of the above technical solution:

[0015] The inner cavity of the sleeve is slidably connected to a movable rod, and the end of the movable rod is fixedly connected to a pressure plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This vacuum constant pressure emulsion nozzle, by rotating the knob, causes the rotating shaft to rotate the second bevel gear, which in turn drives the first bevel gear to rotate, causing the lead screw to rotate. Then, the rotation of the lead screw, in conjunction with the limiting block, causes the baffle to move longitudinally, thereby adjusting the height of the baffle. When the baffle is at the top, the pressing head is quickly blocked by the baffle when pressed, resulting in a shorter pressing head stroke and less emulsion output from the nozzle. Conversely, when the baffle is at the bottom, the pressing head has a longer pressing stroke, resulting in more emulsion output from the nozzle. This allows the device to adjust the amount of emulsion output according to demand, avoiding emulsion waste.

[0018] 2. This vacuum constant pressure emulsion nozzle works by pulling the pressure plate outward, causing the pressure plate to drive the movable rod to extend out of the sleeve. Then, by pressing down the pressure plate, the pressure plate and the movable rod drive the sleeve to move, which in turn causes the semi-circular pressure block to press down on the pressing head, thus completing the pressing work of the pressing head. By pulling the movable rod, the overall length of the movable rod and the sleeve can be adjusted, thereby adjusting the lever arm length, which reduces the force required to press down the pressing head, making the emulsion nozzle easier to press.

[0027] This invention provides a vacuum constant pressure emulsion nozzle that can adjust the output emulsion volume according to needs, avoiding emulsion waste, and making the emulsion nozzle easy to press. Please refer to [link / reference]. Figure 1-4 This includes a connecting box 100 and a mounting cover 200;

[0028] Please see Figure 1-4 A lead screw 110 is rotatably connected to the bottom left side of the inner cavity of the connecting box 100. A first bevel gear 111 is fixedly connected to the lower side of the outer wall of the lead screw 110. A baffle 120 is screwed to the upper side of the outer wall of the lead screw 110. A rotating shaft 130 is rotatably connected to the left side wall of the connecting box 100. The right end of the rotating shaft 130 passes through the connecting box 100 and extends into the inner cavity of the connecting box 100. A second bevel gear 131 is fixedly connected to the right end of the rotating shaft 130. The second bevel gear 131 and the first bevel gear 120 are connected to each other. Gear 111 meshes and rotates. A knob 140 is fixedly connected to the left end of the rotating shaft 130. A limiting groove 150 is formed on the left side wall of the inner cavity of the connecting box 100. A limiting block 160 is slidably connected to the inner cavity of the limiting groove 150. The limiting block 160 is fixedly connected to the left side wall of the baffle 120. A bottle cap 170 is fixedly connected to the bottom of the connecting box 100. An internal thread 171 is provided on the inner side wall of the bottle cap 170. A nozzle body 180 is fixedly connected to the top of the inner cavity of the bottle cap 170. A straw 181 is fixedly connected to the bottom of the body 180, and a pressing head 190 is slidably connected to the top of the connecting box 100. A liquid outlet 191 is fixedly connected to the right side wall of the pressing head 190. The liquid outlet 191 is connected to the nozzle body 180. By rotating the knob 140, the rotating shaft 130 drives the second bevel gear 131 to rotate, which in turn drives the first bevel gear 111 to rotate, causing the lead screw 110 to rotate. In conjunction with the limiting block 160, the baffle 120 moves longitudinally to adjust its height. When the baffle 120 is at the top, the pressing head 190 is quickly blocked by the baffle 120 when it is pressed, resulting in a shorter stroke of the pressing head 190 and less emulsion output from the nozzle body 180. Conversely, when the baffle 120 is at the bottom, the pressing head 190 has a longer downward stroke, resulting in more emulsion output from the nozzle body 180.

[0029] In summary, this allows the device to adjust the amount of emulsion output according to demand, thus avoiding emulsion waste.

[0030] Please see Figure 1-3 The mounting cover 200 is fixedly connected to the top of the connecting box 100. The inner right side wall of the mounting cover 200 is rotatably connected to the sleeve 210. The bottom of the sleeve 210 is fixedly connected to the semi-circular pressure block 220. The inner cavity of the sleeve 210 is slidably connected to the movable rod 230. The end of the movable rod 230 is fixedly connected to the pressure plate 240. By pulling the pressure plate 240 outward, the pressure plate 240 drives the movable rod 230 to extend out of the sleeve 210. Then, by pressing down the pressure plate 240, the pressure plate 240 and the movable rod 230 drive the sleeve 210 to move, thereby causing the semi-circular pressure block 220 to press down on the pressing head 190, thus completing the pressing work of the pressing head 190. By pulling the movable rod 230, the overall length of the movable rod 230 and the sleeve 210 is adjusted, thereby adjusting the lever arm length and reducing the force required to press down on the pressing head 190.

[0031] In summary, this makes the emulsion nozzle easy to press.

[0032] In practical use, those skilled in the art first install the emulsion nozzle onto the emulsion bottle using the bottle cap 170 and internal thread 171. Then, by rotating the knob 140, the rotating shaft 130 drives the second bevel gear 131 to rotate, which in turn drives the first bevel gear 111 to rotate, causing the lead screw 110 to rotate. Then, by rotating the lead screw 110 and cooperating with the limiting block 160, the baffle 120 moves longitudinally, thereby adjusting the baffle 120 to the appropriate position. Then, by pulling the pressure plate 240 outward, the pressure plate 240 drives the movable rod 230 to extend out of the sleeve 210. Then, by pressing down the pressure plate 240, the pressure plate 240 and the movable rod 230 drive the sleeve 210 to move, which in turn causes the semi-circular pressure block 220 to press down the pressing head 190. When the pressing head 190 reaches the required position, the baffle 120 will block the pressing head 190 from continuing to press down, so that the nozzle body 180 completes the quantitative output of emulsion.
