Description

Technical Field

[0001] The utility model belongs to the technical field of sprayers and relates to a sprayer. Background Art

[0002] Sprayers are one of the most widely used tools in agricultural production, providing a simple and convenient way to spray water mist. Currently, they are not only used in agricultural production, but are also suitable for sanitation and epidemic prevention, as well as disinfection in hotels, greenhouses, and warehouses. Therefore, sprayers are widely used for spraying and pest control on flowers, bonsai, and nurseries; for pest control on small plots of farmland, vegetables, and fruit trees; for spraying various perfumes, cleaning agents, detergents, and detergents in homes and public places; and for cleaning furniture and glass with water.

[0003] However, current sprayers pre-mix the liquid medicine according to the desired concentration. The mixed liquid medicine is then pumped directly into a liquid tank, increasing its kinetic energy and overcoming pipe resistance, thereby achieving atomized spraying. The atomized liquid medicine is then sprayed onto the surface of crops and other targets for pest control, weed control, and disease prevention. However, practical drawbacks often arise. For example, users cannot precisely control the mixing ratio of the liquid medicine during dispensing, resulting in haphazard mixing of the liquid medicine, which can lead to the actual effect being less than expected. Furthermore, users cannot accurately estimate the required amount of liquid medicine, often leaving some liquid medicine in the tank after spraying. When this is inconvenient to retain, it can be discarded, polluting the environment and causing waste. When multiple liquid medicines need to be sprayed, the liquid medicine in the tank must be frequently cleaned and replaced, making it inconvenient to use. Furthermore, after the liquid medicine is atomized by the pump, it corrodes the pump, reducing its service life. Summary of the Invention

[0004] The purpose of the utility model is to solve the above problems existing in the prior art and to provide a sprayer that can easily switch between different liquid medicines by replacing the medicine box.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a sprayer, comprising a water tank, a medicine box, a pressure pump, and a proportional dosing pump, the water tank being located above the pressure pump and connected to the pressure pump, the pressure pump being provided with a water delivery pipe, the medicine box and the proportional dosing pump being both installed on the side of the water tank, the proportional dosing pump being located above the pressure pump, the proportional dosing pump comprising an inlet, an outlet, and a drug suction pipe, the medicine box being located outside the water tank, the end of the drug suction pipe being inserted into the medicine box, the end of the water delivery pipe being connected to the inlet of the proportional dosing pump, and the outlet of the proportional dosing pump being provided with a drug delivery pipe.

[0006] In the above-mentioned sprayer, two first fixing blocks are fixed to the side of the water tank, and a plurality of first fixing holes are formed on the first fixing blocks. Second fixing blocks are fixed to the sides of the medicine box and the proportional dosing pump, and a plurality of second fixing holes corresponding to the first fixing holes are formed transversely through the second fixing block. An insertion groove is formed longitudinally on the second fixing block, and a bolt and a nut are provided on the second fixing block. The first fixing block is inserted into the insertion groove, and the bolt passes through the second fixing hole and the first fixing hole and is fastened to the bolt.

[0007] In the above-mentioned sprayer, the first fixing block is fixed to the water tank by welding, and a contact protrusion is formed on the end of the first fixing block, and the contact protrusion contacts the side surface of the water tank.

[0008] In the above-mentioned sprayer, a limiting protrusion is formed on the first fixing block.

[0009] Compared with the prior art, the water tank and the medicine box in this sprayer are independently arranged. The water in the water tank is transported to the proportional dosing pump through the pressure pump and the water delivery pipe. The proportional dosing pump accurately absorbs a certain amount of liquid medicine in the medicine box through the medicine suction pipe. The water and liquid medicine are evenly mixed in the proportional dosing pump and then output through the medicine delivery pipe. There is no need to mix the liquid medicine and water in advance. The matching ratio of the two is accurately controlled by the proportional dosing pump to ensure the use effect of the mixed liquid medicine. At the same time, the liquid medicine is mixed immediately when used, and no residual liquid medicine will be generated, thereby avoiding waste and being beneficial to environmental protection. When it is necessary to spray multiple liquid medicines, the medicine box can be removed and disassembled and replaced. By replacing the medicine box, the purpose of easily switching between different liquid medicines can be achieved, and frequent cleaning of the water tank can be avoided. At the same time, since the liquid medicine in the medicine box is the original liquid, the remaining liquid medicine can still be stored in the medicine box after use, and the concentration will not change, thereby avoiding waste of liquid medicine. The water tank, pressure pump, etc. are only used for storing and pressurizing water, and are not easily corroded by the liquid medicine, thereby extending the service life and reducing maintenance and cleaning work.

DETAILED DESCRIPTION

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 and Figure 2 As shown, the sprayer includes a water tank 1, a medicine box 2, a pressure pump 3, and a proportional dosing pump 4. The water tank 1 is located above the pressure pump 3 and is connected to the pressure pump 3. The pressure pump 3 is provided with a water pipe 5. The medicine box 2 and the proportional dosing pump 4 are both installed on the side of the water tank 1, and the proportional dosing pump 4 is located above the pressure pump 3. The proportional dosing pump 4 includes an inlet, an outlet and a drug suction pipe 41. The medicine box 2 is located outside the water tank 1, and the end of the drug suction pipe 41 is inserted into the medicine box 2. The end of the water pipe 5 is connected to the inlet of the proportional dosing pump 4, and the outlet of the proportional dosing pump 4 is provided with a drug delivery pipe 6. The proportional dosing pump 4 can be purchased directly from the market.

[0015] In the above technical solution, two first fixing blocks 7 are fixed to the side of the water tank 1. The first fixing blocks 7 are formed with a plurality of first fixing holes 71. A second fixing block 8 is fixed to the side of each of the medicine box 2 and the proportional dosing pump 4. The second fixing block 8 has a plurality of second fixing holes 81 extending transversely therethrough, corresponding to the first fixing holes 71. An insertion slot 82 is also formed longitudinally therethrough. Bolts and nuts are provided on the second fixing block 8. The first fixing block 7 is inserted into the insertion slot 82. The bolts are then passed through the second fixing holes 81, the first fixing hole 71, and the second fixing hole 81, in sequence, to be secured to the bolts.

[0016] In the above technical solution, the first fixing block 7 is welded to the water tank 1. A contact protrusion 72 is formed on the end of the first fixing block 7, which contacts the side of the water tank 1. The contact protrusion 72 increases the contact area between the first fixing block 7 and the side of the water tank 1, thereby increasing the connection stability of the first fixing block 7. Of course, the first fixing block 7 can also be fixed using other connection methods or can be integrally formed on the water tank 1.

[0017] In the above technical solution, a limiting protrusion 73 is formed on the first fixing block 7 , and the limiting protrusion 73 limits the insertion process of the first fixing block 7 into the insertion slot, thereby facilitating the alignment of the first fixing hole 71 and the second fixing block 81 .

[0018] In this sprayer, the water tank 1 and the medicine box 2 are independently arranged. The water in the water tank 1 is transported to the proportional dosing pump 4 through the pressure pump 3 and the water delivery pipe 5. The proportional dosing pump 4 accurately draws a fixed amount of liquid medicine in the medicine box 2 through the medicine suction pipe 41. The water and the liquid medicine are evenly mixed in the proportional dosing pump 4 and then output through the medicine delivery pipe 6. There is no need to mix the liquid medicine and water in advance. The matching ratio of the two is accurately controlled by the proportional dosing pump 4 to ensure the use effect of the mixed liquid medicine. At the same time, the liquid medicine is mixed immediately when used, and no liquid medicine is left, which avoids waste and is beneficial to environmental protection. When it is necessary to spray multiple liquid medicines, the medicine box is removed and the medicine box 2 is disassembled and replaced. By replacing the medicine box 2, the purpose of easily switching between different liquid medicines can be achieved, and frequent cleaning of the water tank 1 can be avoided. At the same time, since the liquid medicine in the medicine box 2 is the original liquid, the remaining liquid medicine can still be stored in the medicine box 2 after use, and the concentration will not change, which avoids waste of liquid medicine. The water tank 1, the pressure pump 3, etc. are only used for storing and pressurizing water, and are not easily corroded by the liquid medicine, thereby extending the service life and reducing maintenance and cleaning work.
