Description

Technical Field

[0001] This application relates to the field of spray technology, and more specifically to a stand-alone dual-bottle dual-pipe sprayer. Background Technology

[0002] Currently, in the fields of fine chemicals, pharmaceutical testing, and especially biochemical disinfection and sterilization, the mixing ratio and timing of related biochemical reactions require strict control. In particular, if the two solutions are mixed in minute quantities (PPM level) before the reaction, it can lead to unexpected chemical reactions and affect the expected final reaction outcome.

[0003] Most sprayers on the market today are single-head sprayers, meaning they can only spray one type of solution. Although there are spray bottle designs that can spray two solutions simultaneously, such as the Chinese utility model patent, a dual-tube spray bottle (authorization publication number: CN219822276 U), this design mixes the two solutions in the compression chamber before spraying them out from a single spray nozzle. However, some mixing reactions only produce their effects at the moment of mixing. Premixing not only loses the original effect but also contaminates the original solution stored in the bottle.

[0004] Regarding storage, related designs, such as the Chinese utility model patent for a dual-channel self-mixing sprayer (authorization publication number: CN 212663948 U), employ the concept of storing two liquids in the same bottle, separated only by a partition and a snap-on cap. However, the snap-on cap cannot be screwed on, and when the bottle contains a highly volatile solution, the partition and snap-on cap may not completely isolate the two solutions, leading to leakage and mixing. Furthermore, vigorous shaking during transportation exacerbates this possibility. In use, this design not only makes it inconvenient to replace only one solution, but the compression handles are also independent, preventing the two sprayed solutions from mixing evenly.

[0055] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of this application, and not all of the embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein. Based on the embodiments of this application described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of this application.

[0056] Therefore, in view of the aforementioned technical problems, this utility model proposes an independent dual-bottle dual-pipe sprayer, referring to... Figure 1-9 This describes a stand-alone dual-bottle dual-line sprayer used to implement embodiments of the present invention. For example... Figure 1 , 2 As shown, the independent dual-bottle dual-pipe sprayer includes a first container bottle 4, a second container bottle 5, a dual-channel structure 1, a dual nozzle 2, and a dual compression handle 3.

[0057] The first container bottle 4 and the second container bottle 5 are used to hold solutions. Both are hollow containers with openings at the top. These openings are connected to the first channel 11 and the second channel 12 of the dual-channel structure 1, respectively. The first container bottle 4 and the second container bottle 5 are two independent containers; the solutions in them can be stored independently, and either solution can be freely interchanged. The first end of the dual-channel structure 1 is connected to both the first container bottle 4 and the second container bottle 5, and the first end of the dual-channel structure 1 is connected to the openings of both containers. The second end of the dual-channel structure 1 is connected to the dual-nozzle 2. Figure 4 As shown, the dual-channel structure 1 internally comprises a first channel 11 and a second channel 12. The dual-channel structure 1 is connected to the first container bottle 4, the second container bottle 5, and the dual nozzle 2 via threaded connections. The first channel 11 is threaded to the opening of the first container bottle 4, and the second channel 12 is threaded to the opening of the second container bottle 5. The first channel 11 and the second channel 12 are two independent channels, preventing premature mixing and reaction of the solutions in the containers. Regardless of the usage or transportation environment, the two solutions within the device are stored separately in two containers and two channels, preventing leakage and mixing.

[0058] The dual nozzle 2 includes a first nozzle structure 21 and a second nozzle structure 22 for spraying a solution mist. The first nozzle structure 21 and the second nozzle structure 22 are arranged adjacent to each other, and the solution mists sprayed by the first nozzle structure 21 and the second nozzle structure 22 can mix instantly in the air. The first end of the first channel 11 is connected to the first container bottle 4, and the second end of the first channel 11 is connected to the first nozzle structure 21; the first end of the second channel 12 is connected to the second container bottle 5, and the second end of the second channel 12 is connected to the second nozzle structure 22.

[0059] The dual-compression handle 3 is connected to the first nozzle structure 21 and the second nozzle structure 22. The connection between the dual-compression handle 3 and the first nozzle structure 21 and the second nozzle structure 22 can be a snap-fit ​​connection. When the dual-compression handle 3 is pressed, the solution in the first container bottle 4 is sprayed out through the first channel 11 from the first nozzle structure 21, and the solution in the second container bottle 5 is sprayed out through the second channel 12 from the second nozzle structure 22. The solutions in the first container bottle 4 and the second container bottle 5 mix during spraying.

[0060] The independent dual-bottle dual-pipe sprayer according to an embodiment of this utility model features two independent container bottles for storing the solution, two independent pipes for transporting the solution, and two independent nozzles for spraying the solution. A dual-compression handle 3 allows simultaneous control of both nozzle structures. During use, it not only controls the spraying of two different solutions but also ensures thorough mixing of the sprayed solutions at a suitable distance. This design prevents leakage and mixing of the solutions in the two container bottles during use and transportation; mixing only occurs at the moment of spraying. Furthermore, it allows for easy and convenient replacement of either solution bottle.

[0061] In the embodiments of this application, the first nozzle structure 21 and the second nozzle structure 22 of the dual nozzle 2 are fixedly connected at a specified angle via a connecting structure; the specified angle is 20°-25°, so that the solution sprayed from the first nozzle structure 21 mixes with the solution sprayed from the second nozzle structure 22. At this angle, the mixing area of ​​the solutions sprayed from the two nozzle structures is maximized, such as... Figure 10 As shown, an angle that is too small will prevent the two solutions from mixing, while an angle that is too large will prevent the two solutions from mixing over a maximum area, resulting in only a small area of ​​mixing. Figure 7As shown, the connecting structure can be a housing. After the first nozzle structure 21 and the second nozzle structure 22 are fixedly connected through the housing, it prevents the two nozzle structures from shaking when the dual compression handle 3 is pressed. The fixed connection can be a welded connection. At a specified angle, the ends of the two nozzle structures that spray the solution are close together, and the solutions sprayed by the two nozzle structures will mix at the moment of spraying. For example, the first nozzle structure 21 and the second nozzle structure 22 of the dual nozzle 2 are hand-operated sprayers made of polyethylene material, which is chemically stable and does not easily react with the solution. For example, the first nozzle structure 21 and the second nozzle structure 22 can be dual-mode nozzles, which can spray the solution as a water mist or as a water jet. They can be freely switched according to the usage scenario to achieve the best product performance. Figure 2 As shown, exemplarily, the first nozzle structure 21 and the second nozzle structure 22 may not have a connecting structure; they are simply connected by the dual compression handle 3. When the dual compression handle 3 is connected to the first nozzle structure 21 and the second nozzle structure 22, the first nozzle structure 21 and the second nozzle structure 22 are positioned adjacent to each other at a specified angle. Exemplarily, the dual compression handle 3 is also ergonomically designed with a certain curvature, allowing users to press it more easily. This ensures convenient use while also guaranteeing the normal operation of the nozzle device, enabling it to spray sufficient solution to achieve the best product performance.

[0062] For example, the device may have two independent pipes, a first pipe and a second pipe. The first pipe connects the first container bottle 4, the first channel 11, and the first nozzle structure 21. The second pipe connects the second container bottle 5, the second channel 12, and the second nozzle structure 22. The solutions in the two containers are respectively transferred to the dual nozzle 2 through the two pipes to complete the spraying action. For example, the first container bottle 4 and the second container bottle 5 are made of polyethylene, which is pressure-resistant, wear-resistant, and has stable physical and chemical properties.

[0063] like Figure 6 As shown in the embodiments of this application, the first nozzle structure 21 includes a first pressing part 211 and a first nozzle head 212, the first pressing part 211 causing the first nozzle head 212 to spray out solution; the second nozzle structure 22 includes a second pressing part 221 and a second nozzle head 222, the second pressing part 221 causing the second nozzle head 222 to spray out solution. When the first pressing part 211 is pressurized, the air compression mechanism operates, causing the liquid in the first container bottle 4 to rise through the connected first pipe and spray out from the first nozzle head 212. When the second pressing part 221 is pressurized, the air compression mechanism operates, causing the liquid in the second container bottle 5 to rise through the connected second pipe and spray out from the second nozzle head 222. At a specified angle, the first nozzle head 212 and the second nozzle head 222 are arranged close together, and the sprayed solutions mix at the moment of spraying.

[0064] like Figure 8 As shown in the embodiment of this application, the dual-compression handle 3 is provided with a first groove 31 and a second groove 32 inside: a first pressing part 211 is inserted into the first groove 31, and the first groove 31 cooperates with the first pressing part 211; a second pressing part 221 is inserted into the second groove 32, and the second groove 32 cooperates with the second pressing part 221; when the dual-compression handle 3 is pressed, the first pressing part 211 and the second pressing part 221 are pressed simultaneously, and the first nozzle 212 and the second nozzle 222 spray out solution simultaneously. The dual-compression handle 3 can drive the first pressing part 211 and the second pressing part 221 to move. When the dual-compression handle 3 is pressed, the first pressing part 211 and the second pressing part 221 are pressed simultaneously, thereby causing the first nozzle 212 and the second nozzle 222 to spray out solution simultaneously. This prevents the two pressing parts of the two independent nozzle structures from not being able to be stressed simultaneously during manual operation, which would cause the two nozzles to not spray solution simultaneously, reducing errors and making the spraying more precise. For example, when the dual compression handle 3 is pressed, the ratio of the solution sprayed by the first nozzle 212 to the second nozzle 222 is 1:1. If the ratio of the sprayed solution needs to be adjusted, different specifications of the same nozzle can be replaced as needed to adjust the ratio of the sprayed solution.

[0065] like Figure 9 As shown in the embodiment of this application, the surface of the dual compression handle 3 is provided with a first protrusion 33 and a second protrusion 34: the first protrusion 33 is inserted into the first pressing part 211 to fix the connection between the first pressing part 211 and the first groove 31; the second protrusion 34 is inserted into the second pressing part 221 to fix the connection between the second pressing part 221 and the second groove 32. Exemplarily, the first pressing part 211 and the second pressing part 221 are respectively provided with holes. The first protrusion 33 of the dual compression handle 3 is inserted into the hole of the first pressing part 211 to fix the connection between the first pressing part 211 and the first groove 31, and the second protrusion 34 of the dual compression handle 3 is inserted into the hole of the second pressing part 221 to fix the connection between the second pressing part 221 and the second groove 32, preventing the dual compression handle 3 from detaching from the first pressing part 211 and the second pressing part 221. Align the first groove 31 and second groove 32 of the dual-compression handle 3 with the first pressing part 211 and second pressing part 221 of the dual-nozzle 2, and forcefully slip it on. The first protrusion 33 and second protrusion 34 of the dual-compression handle 3 will then insert into the holes of the first pressing part 211 and second pressing part 221. This allows the dual-compression handle 3 to control the first nozzle structure 21 and the second nozzle structure 22 of the dual-nozzle 2 for simultaneous spraying. For example, a user can press the dual-compression handle 3 with one hand to spray a mixture of two solutions in a suitable ratio, making it simple and convenient to operate with one hand. In use, the user holds the dual-channel structure 1 and uses their index and middle fingers to press the dual-compression handle 3 to simultaneously spray solutions from two containers.

[0066] like Figure 3 As shown in the embodiments of this application, the first end of the dual-channel structure 1 is provided with a first connecting cap 13 and a second connecting cap 14; the second end of the dual-channel structure 1 is provided with a first connector 15 and a second connector 16; the first end of the first channel 11 is connected to the first container bottle 4 through the first connecting cap 13, and the second end of the first channel 11 is connected to the first nozzle structure 21 through the first connector 15; the first end of the second channel 12 is connected to the second container bottle 5 through the second connecting cap 14, and the second end of the second channel 12 is connected to the second nozzle structure 22 through the second connector 16. There is a certain distance between the first connecting cap 13 and the second connecting cap 14 to facilitate the connection between the first connecting cap 13 and the opening of the first container bottle 4, and the connection between the second connecting cap 14 and the opening of the second container bottle 5. The distance between the first connecting cap 13 and the second connecting cap 14 is determined according to the size of the first container bottle 4 and the second container bottle 5. There is a certain distance between the first connector 15 and the second connector 16, which facilitates the connection between the first connector 15 and the first nozzle structure 21, and the connection between the second connector 16 and the second nozzle structure 22. The distance between the first connector 15 and the second connector 16 is determined according to the size of the first nozzle structure 21 and the second nozzle structure 22. For example, the first channel 11 and the second channel 12 of the dual-channel structure 1 are made of antibacterial and smooth material and are integrally injection molded. This also facilitates cleaning and disinfection by users, allows for repeated use, and the device structure conforms to ergonomic design, making it convenient for medical personnel to use.

[0067] like Figure 5 As shown, in the embodiments of this application, the inner surfaces of the first connecting cover 13 and the second connecting cover 14 are provided with a first internal thread 1a; the outer surfaces of the first connector 15 and the second connector 16 are provided with a first external thread 1b.

[0068] In the embodiments of this application, the first container bottle 4 and the second container bottle 5 are provided with a second external thread on the outer surface near the dual-channel structure 1, and the second external thread matches the first internal thread 1a. The openings of the first container bottle 4 and the second container bottle 5 are provided with a second external thread, which matches the first internal thread 1a on the inner surface of the first connecting cap 13 and the second connecting cap 14. The first container bottle 4 and the second container bottle 5 can be disassembled and assembled with the dual-channel structure 1 through the second external thread, which not only achieves complete independence of the two solutions in the first container bottle 4 and the second container bottle 5, but also facilitates the replacement of the first container bottle 4 and the second container bottle 5. Before spraying, the first container bottle 4 and the second container bottle 5 are disassembled, and the two solutions are poured into the first container bottle 4 and the second container bottle 5 respectively. After tightening the first container bottle 4 to the first connecting cap 13 by threaded connection, the second container bottle 5 to the second connecting cap 14 is tightened by threaded connection. This avoids the two solutions from mixing prematurely when adding the two solutions to the two cavities of one bottle.

[0069] In the embodiments of this application, the inner surface of the dual-nozzle 2 near the dual-channel structure 1 is provided with a second internal thread, which matches the first external thread 1b. The first nozzle structure 21 and the second nozzle structure 22 of the dual-nozzle 2 can be disassembled and reassembled with the dual-channel structure 1 through the second internal thread.

[0070] In the embodiments of this application, the first internal thread 1a, the first external thread 1b, the second internal thread, and the second external thread are triangular threads. Triangular threads have good self-locking properties, high strength, and high stability, preventing solution leakage due to thread loosening during use.

[0071] This application discloses an independent dual-bottle, dual-pipe sprayer. It features two independent container bottles for storing the solution, two independent pipes for transmitting the solution, and two independent nozzles for spraying the solution. A dual-compression handle allows simultaneous control of both nozzle structures, enabling them to combine at a specific angle. During use, this not only allows for the spraying of two different solutions but also ensures thorough mixing of the sprayed solutions at a suitable distance. This prevents leakage and mixing of the solutions in the two container bottles during use and transportation, ensuring mixing only occurs at the moment of spraying. Furthermore, it allows for easy and convenient replacement of either solution bottle.
