Description

Technical Field

[0001] This utility model relates to the field of liquid dispensing nozzles, specifically a press-piston type nozzle. Background Technology

[0002] A typical spray bottle structure consists of core components such as a nozzle, pump body (or air pressure system), bottle body, pipe, atomizing nozzle (or cap), and sealing components. These components work together to achieve the function of liquid atomization and spraying. However, the existing spray bottle structure has a relatively simple liquid dispensing method. When a large flow rate is required to pour in different situations, the nozzle needs to be unscrewed. The nozzle is screwed onto the bottle mouth by threads. In order to ensure the seal at the bottle mouth, both the nozzle and the bottle mouth need to be sealed. Some of these are difficult to unscrew. In addition, there is currently no spray head structure on the market that combines pouring and spraying, so the liquid dispensing method cannot be switched according to user needs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-6 In this embodiment of the utility model, a press-piston type nozzle is used to screw and fasten onto the threaded opening of a bottle so that the liquid inside the bottle can be atomized and sprayed out, comprising: The housing 1 has a handle structure. The housing 1 is a hollow housing with an open top. The housing is composed of two half-shells that are interlocked by columnar, plate-shaped or other positioning structures distributed on its inner wall. The lower end of the housing 1 has a ring-shaped structure, and the inner side wall of the lower ring of the housing 1 is provided with a thread that matches the threaded opening of the bottle. A flip cover 4 is installed on the upper side wall of the housing 1. Pipe 2 is installed and fixed in the inner cavity of the shell 1. Pipe 2 is a tee pipe, with two of its openings extending to the upper opening flap 4 of the shell 1 and penetrating the bottom of the inner cavity of the shell 1, respectively. Atomizing nozzle 3 is located on one side of pipe 2 and is installed through the upper side wall of housing 1; The suction assembly 6 is installed on another port of the pipe 2. The input end of the suction assembly 6 is located inside the pipe 2 and is connected to a second conduit 8. The second conduit 8 enters the bottle body along the pipe 2. The output end of the suction assembly 6 is connected to the input end of the atomizing nozzle 3 through a first conduit 7. The suction assembly 6 generates negative pressure to draw liquid from the bottle body so that the drawn liquid is sprayed out by the atomizing nozzle 3.

[0021] In this embodiment, the pipe 2 and the suction assembly 6 work together to achieve two liquid dispensing methods: one is to tilt the pipe 2 so that the liquid flows out of the bottle through the upper and lower openings; the other is to use the suction assembly 6 to generate negative pressure to draw the liquid out of the bottle and spray it out through the atomizing nozzle 3, thus meeting the user's needs in different situations. The pipe 2, atomizing nozzle 3, flip cap 4, and suction assembly 6 are all located in the middle of the housing 1 and are locked together between the two halves of the housing for easy assembly and disassembly.

[0022] Specifically, this solution involves a nozzle installed at the bottle opening, which is threadedly connected to the bottle opening. When a large flow of liquid needs to be poured, the handle on the housing 1 is gripped, causing the bottle to tilt. Under the influence of gravity, the liquid inside the bottle enters through the opening at the lower end of the pipe 2 and flows out through the opening at the upper end of the pipe 2 near the opening of the housing 1, thus achieving a large flow of liquid pouring. When a small flow of spraying is needed, the suction assembly 6 generates a negative pressure airflow, and the lower end of the second conduit 8 draws the liquid inside the bottle. The liquid is then transported to the atomizing nozzle 3 through the suction assembly 6 and the first conduit 7, and finally atomized and sprayed out using the atomizing nozzle 3. It should be noted that the atomizing nozzle 3 in this solution is an atomizing nozzle currently available on the market, and will not be elaborated on further here.

[0023] Please refer to this carefully. Figures 1-6 The nozzle also includes a flip cover 4. The middle part of the flip cover 4 is rotatably connected to the upper opening end of the housing 1 via a shaft. A limiting slider 5 that is slidably connected to the top of the housing 1 is provided on one side of the flip cover 4. A limiting insert 51 is integrally formed on the end face of the limiting slider 5 facing the flip cover 4. A limiting slot 41 for the limiting insert 51 to be inserted is provided on the end face of the flip cover 4 corresponding to the limiting insert 51. The lower end of the flip cover 4 is provided with a plug 42 for sealing one of the pipe openings of the pipe 2. The plug 42 is a rubber block.

[0024] In this embodiment: by providing a rotatably connected flip cover 4 at the opening of the housing 1, when the flip cover 4 is flipped open, the plug 42 at the bottom of the flip cover 4 will release the blockage of the opening at the upper end of the pipe 2 near the upper opening of the housing 1, which facilitates the subsequent large-flow liquid pouring; conversely, by fastening the flip cover 4 and pushing the limiting slider 5 to move, the limiting plug 51 is inserted into the limiting slot 41, thereby restricting the rotation of the flip cover 4. At the same time, the plug 42 is also pressed tightly against the opening at the upper end of the pipe 2 to prevent liquid from flowing out when pouring.

[0025] Please see Figure 4 The suction assembly 6 includes a pump core 6-1, and a suction head 6-2 is integrally formed at the lower end of the pump core 6-1. The suction head 6-2 has a through hole that communicates with the inner cavity of the pump core 6-1, and a second conduit 8 is connected to the input end of the suction head 6-2. The suction assembly 6 also includes a connecting post 6-3, the upper end of which is integrally formed with a pressing head 6-4, and the lower end of the connecting post 6-3 is slidably connected and communicates with the pump core 6-1; a drain head 6-0 is provided on the outer wall of the upper end of the connecting post 6-3, and the drain head 6-0 communicates with the first conduit 7; the pressing head 6-4 extends to the outside of the housing 1 and can be pressed so that the liquid enters the second conduit 8, the suction head 6-2, and the pump core 6-1 from the bottle in sequence, and enters the first conduit 7 from the connecting post 6-3 and the drain head 6-0 and is sprayed out from the atomizing nozzle 3.

[0026] Both the first conduit 7 and the second conduit 8 are soft rubber tubes. One end of the first conduit 7 is connected to the outer end of the drain head 6-0, and the other end of the first conduit 7 is connected to the input end of the atomizing nozzle 3. One end of the second conduit 8 is connected to the lower end of the suction head 6-2.

[0027] In this embodiment, the suction assembly 6 generates negative pressure by reciprocating pressing and suction. Specifically, by controlling the pressing head 6-4, the connecting column 6-3 is forced to move inside the pump core 6-1, so that the liquid in the bottle flows into the suction head 6-2 through the second conduit 8, then flows to the drain head 6-0 through the pump core 6-1, and then the liquid in the suction assembly 6 is delivered to the atomizing nozzle 3 through the first conduit 7, and finally the liquid is atomized and sprayed out through the atomizing nozzle 3.

[0028] Please refer to this carefully. Figure 7 In another embodiment, the pump core 6-1 specifically includes a piston 601, a sealing ring 603, and a spring 604; a limiting baffle 605 and a first ball 606 are placed at the lower end of the inner cavity of the pump core 6-1, the limiting baffle 605 is located above the first ball 606, and the upper opening end of the suction head 6-2 is connected to the sealing ring 603 by a thread. The inner diameter of the through hole on the suction head 6-2 is smaller than the outer diameter of the first ball 606, and the outer diameter of the first ball 606 is smaller than the inner diameter of the pump core 6-1; the limiting baffle 605 has a disc-shaped structure, and multiple through holes are provided on the limiting baffle 605. The outer diameter of the limiting baffle 605 matches the inner diameter of the pump core 6-1, and the limiting baffle 605 and the inner wall of the pump core 6-1 are fixedly connected by glue. The connecting column 6-3 moves through the sealing ring 603, and a piston 601 matching the inner diameter of the pump core 6-1 body is installed on the lower outer wall of the connecting column 6-3. The spring 604 is located between the limiting baffle 605 and the piston 601. A stepped groove is provided inside the connecting post 6-3. The small diameter end of the stepped groove is located at the lower end of the connecting post 6-3. A limit post 602 is provided at the top of the stepped groove. A second ball 607 is provided below the limit post 602. The second ball 607 is located inside the large diameter end of the stepped groove. The drain head 6-0 is connected to the stepped groove, and the bottom end of the limiting post 602 is lower than the position height of the drain head 6-0; the inner diameter of the small diameter end of the stepped groove is smaller than the outer diameter of the second sphere 607, and the inner diameter of the large diameter end of the stepped groove is larger than the outer diameter of the second sphere 607. In this embodiment: by pressing the pressing head 6-4, the connecting column 6-3 is forced to drive the piston 601 to descend, and at the same time, the spring 604 is compressed. Since the first ball 606 blocks the upper end of the through hole on the suction head 6-2, the air pressure in the pump core 6-1 is compressed, which in turn pushes the second ball 607 upward, releasing the blockage of the stepped groove by the second ball 607, and the airflow will flow out from the drain head 6-0. When the pressure on the pressing head 6-4 is released, the second ball 607 falls back and continues to block the stepped groove. At the same time, the spring 604 pushes the piston 601 upward, expanding the space of the pump core 6-1. This forces the air pressure at the through hole of the suction head 6-2 to push the first ball 606 upward, releasing the blockage at the through hole of the suction head 6-2. By repeatedly pressing in this way, the liquid in the bottle can flow into the suction assembly 6 through the second conduit 8, and then be transported to the atomizing nozzle 3 through the first conduit 7. Finally, the liquid is atomized and sprayed out through the atomizing nozzle 3.

[0029] Please refer to this carefully. Figure 8 In another embodiment, the suction assembly 6 includes a suction pump head 61, and the suction operation end extends to the outside of the housing 1 to facilitate the user's suction operation. The suction pump head 61 is installed on a port of the pipe 2. The lower port of the pipe 2 is connected to a connecting pipe 62 for extending into the bottle body. A vent hole 63 communicating with the bottle body is opened at the bottom of the inner cavity of the housing. The suction pump head 61 is an existing suction and spray pump structure. The suction pump head 61 uses the input end to draw the pipe 2, so that the liquid enters the pipe through the connecting pipe 62, and then is delivered into the first conduit 7 through the output end of the suction pump head 61, and finally sprayed out by the atomizing nozzle 3. Similarly, in this embodiment, the liquid can also be discharged from another opening at the upper end of the pipe 2 by tilting the bottle.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
