Description

Technical Field

[0001] This utility model relates to the field of mosquito repellent liquid manufacturing technology, and in particular to a mosquito repellent liquid canning and metering mechanism. Background Technology

[0002] Mosquito repellent is a liquid chemical preparation specifically designed to prevent mosquito bites. Its core function is to release specific active ingredients that interfere with the mosquito's olfactory perception or nervous system, thereby effectively reducing the likelihood of mosquitoes approaching a person or a specific area. These products typically contain active ingredients such as DEET, picaridin, and lemon eucalyptus oil (PMD), which achieve their repellent effect by masking mosquito-attracting odors emitted by the human body (such as carbon dioxide and lactic acid) or by directly acting on the mosquito's sensory system. Mosquito repellent is commonly available in spray and lotion forms and is suitable for protecting exposed skin during outdoor activities.

[0003] In the prior art, there is a Chinese utility model patent with publication number "CN220682822U" and patent name "A mosquito repellent liquid canning and metering mechanism". This patent describes a technical solution such as "by setting a driving mechanism, a moving mechanism can be driven to rotate in both directions inside the metering cylinder, so that the cleaning mechanism will move back and forth vertically inside the metering cylinder as the moving mechanism rotates, thereby wiping and cleaning the mosquito repellent liquid remaining on the inner wall of the metering cylinder conveniently and quickly, thus ensuring the accuracy of the metering cylinder when measuring other substances, and also extending the service life of the metering cylinder".

[0004] However, in actual use, although this technical solution can improve the accuracy of metering by wiping the mosquito repellent on the inner wall of the metering cylinder with the cleaning sponge ring as it moves up and down, the cleaning sponge ring is difficult to disassemble after cleaning. This leads to the repellent being contaminated by the residue on the cleaning sponge ring when it is added to the metering cylinder. Furthermore, the cleaning sponge ring absorbs some of the mosquito repellent, causing changes in the liquid level inside the metering cylinder, which affects the accuracy of the metering. At the same time, because the size of the fixing ring is fixed, it is impossible to clean metering cylinders of different sizes. And simply wiping with the sponge ring up and down is not enough to effectively remove the residue attached to the inner wall of the metering cylinder. Therefore, the applicability and practicality of this technical solution and the cleaning effect on the metering cylinder are reduced.

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a mosquito repellent liquid filling and metering mechanism. Utility Model Content

[0006] The main objective of this invention is to provide a mosquito repellent liquid dispensing and metering mechanism that can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A mosquito repellent liquid dispensing and metering mechanism includes a support base, a metering can fixedly connected to the top surface of the support base, and a cleaning mechanism inside the metering can. The cleaning mechanism includes a vertical cylinder, a bidirectional adjusting screw, adjusting discs, a scraper, a connecting rod, a concave seat, a drive motor, and a drive motor. The drive motor is fixedly connected to the top of the mounting opening on the top surface of the metering can, and the concave seat is fixedly connected to the output end of the drive motor. The vertical cylinder is fixedly connected to the bottom end of the concave seat, and the bidirectional adjusting screw is movably connected to the inside of the vertical cylinder through first rotating rods at both ends. The drive motor is fixedly connected to the concave seat, and the output end of the drive motor is fixedly connected to the first rotating rod. The two adjusting discs are movably connected to the bidirectional adjusting screw through screw holes on the top surface, and the connecting rod is movably connected between the adjusting disc and the scraper through second rotating rods at both ends.

[0009] Preferably, an inlet pipe and an installation port are fixedly installed on the top surface of the metering tank, and an outlet pipe is fixedly connected to the bottom surface of the metering tank. A level gauge is fixedly installed on the outer wall of the metering tank. A metering pump is fixedly installed inside the support base, and a connecting pipe is fixedly installed between the input end of the metering pump and the outlet pipe. A filling pipe is fixedly installed on the output end of the metering pump, and a filling head is fixedly installed at the bottom end of the filling pipe.

[0010] Preferably, a set of symmetrical sliding openings are provided on the outer wall of the vertical cylinder, and a first rotating hole is provided on the top and bottom surfaces of the vertical cylinder, a concave seat is fixedly installed at the top of the vertical cylinder, the drive motor is fixedly installed at the top of the mounting port, and the output end of the drive motor is fixedly installed together with the concave seat.

[0011] Preferably, the upper and lower ends of the bidirectional adjusting screw are respectively fixedly installed with a first rotating rod, and the first rotating rod is movably installed in the first rotating hole. The drive motor is fixedly installed on the inner top surface of the concave seat, and the output end of the drive motor is fixedly installed together with the upper first rotating rod.

[0012] Preferably, the top surface of the adjusting plate is provided with a screw hole, and the adjusting plate is threadedly connected to the bidirectional adjusting screw through the screw hole. A set of symmetrical sliders are fixedly installed on the outer wall of the adjusting plate, and the sliders are movably installed in the sliding opening. A concave block is fixedly installed on the outer wall of the slider, and a second rotating hole is provided on both sides of the inner wall of the concave opening of the concave block.

[0013] Preferably, the scraper is provided with a symmetrical set that is close to the inner wall of the metering tank, and a set of symmetrical concave blocks are also fixedly installed on the inner side wall of the scraper. A set of symmetrical second rotating rods are fixedly installed at both ends of the connecting rod, and the second rotating rods are movably installed in the second rotating hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the liquid level of the mosquito repellent liquid in the metering tank can be monitored by a liquid level gauge, and the metering pump can accurately and quantitatively extract the mosquito repellent liquid from the metering tank through the liquid outlet pipe via the connecting pipe on the input end, and then transport it to the filling pipe installed on the output end. The filling head can then position and fill it into the mosquito repellent liquid container to achieve filling and metering during the production of the mosquito repellent liquid.

[0016] In conjunction with the cleaning mechanism, when it is necessary to clean the residue on the inner wall of the metering tank, the drive motor can be pre-installed on the top surface of the mounting port. Turning on the drive motor drives the bidirectional adjusting screw to rotate via the first rotating rod. This causes the symmetrical adjusting discs to move in opposite directions along the bidirectional adjusting screw through the screw holes, forcing the connecting rods on both sides of the vertical cylinder to tilt. The angle between the upper and lower symmetrical connecting rods will gradually increase, causing the symmetrical scrapers to move in opposite directions until the scrapers are tightly against the inner wall of the metering tank. Then, the drive motor can be turned on to drive the vertical cylinder to rotate via the concave seat, causing the vertical... The scrapers on both sides of the cylinder rotate closely against the inner wall of the metering can under the drive of the connecting rod, scraping off the residue on the inner wall of the metering can during the rotation. This achieves the purpose of effectively cleaning the metering can. Compared with the existing technology, it can avoid the problem of secondary pollution of mosquito repellent by residue and the problem of reducing the accuracy of mosquito repellent measurement. At the same time, it also avoids the problem of mosquito repellent absorption and reduced measurement accuracy when cleaning the sponge ring. By adjusting the distance between the scrapers, metering cans of different sizes can be cleaned, thereby improving the applicability and practicality of the cleaning mechanism and the cleaning effect on the metering can.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 5 As shown, a mosquito repellent liquid dispensing and metering mechanism includes a support base 1, a metering tank 2 fixedly connected to the top surface of the support base 1, a cleaning mechanism 11 inside the metering tank 2, and the cleaning mechanism 11 including a vertical cylinder 12, a bidirectional adjusting screw 15, an adjusting plate 17, a scraper 22, a connecting rod 23, a concave seat 25, a drive motor 26, and a drive motor 27.

The two adjusting plates 17 are movably connected to the bidirectional adjusting screw 15 through screw holes 18 on the top surface, and the connecting rod 23 is movably connected between the adjusting plate 17 and the scraper 22 through second rotating rods 24 at both ends.

[0025] like Figure 1As shown, the top surface of the metering tank 2 is fixedly equipped with an inlet pipe 3 and an installation port 5, and the bottom surface of the metering tank 2 is fixedly connected with an outlet pipe 4. A level gauge 6 is fixedly installed on the outer wall of the metering tank 2. A metering pump 7 is fixedly installed inside the support base 1, and a connecting pipe 8 is fixedly installed between the input end of the metering pump 7 and the outlet pipe 4. A filling pipe 9 is fixedly installed on the output end of the metering pump 7, and a filling head 10 is fixedly installed at the bottom end of the filling pipe 9. The mosquito repellent liquid for filling can be put into the metering tank 2 through the inlet pipe 3. When the level gauge 6 detects that the mosquito repellent liquid in the metering tank 2 is insufficient, it can also be added to the metering tank 2 through the inlet pipe 3. The metering pump 7 can accurately and quantitatively extract the mosquito repellent liquid from the metering tank 2 through the outlet pipe 4 through the connecting pipe 8 installed on the input end and deliver it to the filling pipe 9 installed on the output end. Finally, the quantitative mosquito repellent liquid can be filled into the container through the filling head 10 at the bottom end of the filling pipe 9 to realize the filling and metering during the production of mosquito repellent liquid.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, a set of symmetrical sliding openings 13 are provided on the outer wall of the vertical cylinder 12. The sliding openings 13 are used to cooperate with the slider 19 to realize the sliding operation. The top and bottom surfaces of the vertical cylinder 12 are respectively provided with first rotating holes 14. The first rotating holes 14 are used to cooperate with the first rotating rod 16 to realize the rotation operation. A concave seat 25 is fixedly installed at the top of the vertical cylinder 12. The drive motor 27 is fixedly installed at the top of the mounting port 5. The output end of the drive motor 27 is fixedly installed together with the concave seat 25. When the drive motor 27 is turned on, the output end can drive the concave seat 25 to rotate. After the concave seat 25 drives the vertical cylinder 12 to rotate, it provides rotational driving force for the scraper 22.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown, the upper and lower ends of the bidirectional adjusting screw 15 are respectively fixedly installed with a first rotating rod 16, and the first rotating rod 16 is movably installed in the first rotating hole 14. The drive motor 26 is fixedly installed on the inner top surface of the concave seat 25, and the output end of the drive motor 26 is fixedly installed together with the first rotating rod 16 at the upper end. When the drive motor 26 is turned on, the output end can drive the bidirectional adjusting screw 15 to rotate through the first rotating rod 16.

[0028] like Figure 3 , Figure 4 and Figure 5As shown, the top surface of the adjusting plate 17 is provided with a screw hole 18, and the adjusting plate 17 is threadedly connected to the bidirectional adjusting screw 15 through the screw hole 18. A set of symmetrical sliders 19 are fixedly installed on the outer wall of the adjusting plate 17, and the sliders 19 are movably installed in the sliding opening 13. A concave block 20 is fixedly installed on the outer wall of the slider 19, and a second rotating hole 21 is provided on both sides of the concave inner wall of the concave block 20. Under the rotation of the bidirectional adjusting screw 15, the upper and lower symmetrical adjusting plates 17 will move in opposite directions through the screw hole 18 on the top surface along the bidirectional adjusting screw 15, and the sliders 19 will move in the sliding opening 13, and drive the concave block 20 installed on the outer wall to move synchronously, so as to achieve the purpose of adjusting the scraper 22 and adapt to the use of metering tanks 2 of different sizes.

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, the scraper 22 is provided with a symmetrical set that is close to the inner wall of the metering tank 2, and a set of symmetrical concave blocks 20 are also fixedly installed on the inner side wall of the scraper 22. A set of symmetrical second rotating rods 24 are fixedly installed at both ends of the connecting rod 23, and the second rotating rods 24 are movably installed in the second rotating holes 21. Since the second rotating rods 24 at both ends of the connecting rod 23 are movably installed in the second rotating holes 21 opened on both sides of the concave inner wall of the concave blocks 20 installed on the outer wall of the slider 19 and the inner wall of the scraper 22, when the adjusting plate 17 moves, the connecting rod 23 will tilt and the angle between the symmetrical connecting rods 23 will increase, pushing the scraper 22 outward until the scraper 22 is close to the inner wall of the metering tank 2. During the rotation, the residue on the inner wall of the metering tank 2 can be scraped off, which can avoid the problem of secondary pollution of mosquito repellent liquid by residue and reduction of the accuracy of mosquito repellent liquid measurement.

[0030] The specific operating principle of the cleaning mechanism 11 in conjunction with the metering tank 2 is as follows:

[0031] Mosquito repellent can be added to metering tank 2 through inlet pipe 3. When filling the mosquito repellent, metering pump 7 installed in support base 1 is turned on. Metering pump 7 will draw out the mosquito repellent from metering tank 2 through outlet pipe 4 at the bottom of metering tank 2 through connecting pipe 8 installed on input end, and deliver it to filling pipe 9 installed on output end. Then, filling head 10 installed at bottom of filling pipe 9 will fill the mosquito repellent into container. During this process, liquid level gauge 6 can monitor the liquid level in metering tank 2 to prevent the liquid level in metering tank 2 from dropping to the preset value. In time, mosquito repellent can be added to metering tank 2 through inlet pipe 3. After metering and filling the mosquito repellent in this way, the consistency of mosquito repellent volume in container can be ensured.

[0032] To prevent mosquito repellent residue inside the metering can 2 from affecting the metering accuracy of subsequent fillings, the metering can 2 needs to be cleaned by the cleaning mechanism 11. Before cleaning, the drive motor 27 can be pre-installed on the top of the mounting opening 5 on the top surface of the support base 1. During cleaning, the drive motor 26 installed in the concave base 25 is turned on according to the size of the metering can 2. The drive motor 26 drives the first rotating rod 16 to rotate in the first rotating hole 14. The first rotating rod 16 will drive the bidirectional adjustment The screw 15 rotates inside the vertical cylinder 12, causing the symmetrical adjusting discs 17 to move in opposite directions along the bidirectional adjusting screw 15 through the screw holes 18 on the top surface. The symmetrical sliders 19 mounted on the outer walls of the adjusting discs 17 slide within the sliding openings 13 on the vertical cylinder 12. At this time, the symmetrical second rotating rods 24 mounted at both ends of the connecting rod 23 are movably installed on the outer walls of the sliders 19 and the inner walls of the scraper 22, respectively, into the second rotating holes 21 on both sides of the inner walls of the corresponding concave blocks 20. Therefore, as the adjusting plate 17 moves, the connecting rod 23 will be forced to tilt, and the angle between the upper and lower symmetrical scrapers 22 will gradually increase. During this change, the scrapers 22 will be pushed outward until they are in close contact with the inner wall of the metering tank 2. The distance between the scrapers 22 can be adjusted in this way to accommodate metering tanks of different sizes. Finally, the drive motor 27 is turned on to drive the output end to rotate the concave seat 25. After the concave seat 25 rotates the vertical cylinder 12, the scrapers 22 are pressed against the inner wall of the metering tank 2 by the connecting rod 23. During the rotation, the residue attached to the inner wall is scraped off, thus achieving the purpose of effectively cleaning the metering tank 2. Compared with the existing technology, it can avoid the problem of secondary pollution of mosquito repellent liquid by residue and the problem of reducing the accuracy of mosquito repellent liquid measurement. At the same time, it also avoids the problem of mosquito repellent liquid absorption and reduced measurement accuracy when cleaning the sponge ring. This improves the applicability and practicality of the cleaning mechanism 11 and the cleaning effect on the metering tank 2.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
