Description

[Technical Field] This invention relates to a nozzle device that is easy to assemble. [Background Technology] Currently, to facilitate the dispensing of substances from the inner cavity of containers, spray nozzle devices are commonly used to spray the substances from the inner cavity. When performing the reset step, modern spray nozzle devices typically use springs made of metal, plastic, silicone, or other elastic materials to reset them. However, using springs for reset results in high manufacturing costs, complex structures, and safety issues for both the spray nozzle device and the container.

[0003] In addition, nozzle devices that use air springs for reset have assembly difficulties during factory assembly.

[0004] Therefore, this invention addresses the aforementioned problems. [Summary of the Invention] The purpose of this invention is to overcome the shortcomings of the prior art and provide a nozzle device that is easy to assemble. It can improve the problems existing in the prior art and has the characteristics of simple structure, safety and reliability, low cost and convenient assembly.

[0006] This invention is achieved through the following technical solution: A nozzle device that is easy to assemble includes a hollow base 1, on which a movable component 2 is slidably connected. The movable component 2 is connected to a valve component 3 located inside the base 1. A temporary storage cavity 4 is formed between the valve component 3 and the base 1. When the movable component 2 slides downward relative to the base 1, the temporary storage cavity 4 is used to isolate itself from the inner cavity of the container and communicate with the outside. When the movable component 2 slides upward relative to the base 1, the temporary storage cavity 4 is used to communicate with the inner cavity of the container and isolate itself from the outside. A sealing cavity 20 is provided on the base 1 or the movable component 2. A movable part 10 that can slide and cooperate with the sealing cavity 20 is provided on the movable component 2 or the base 1. An air outlet control structure 5 is provided between the movable component 2 and the valve component 3 to control the communication between the sealing cavity 20 and the outside and to control the isolation between the sealing cavity 20 and the outside when the movable component 2 moves relative to the valve component 3 for the first time.

[0007] As described above, a nozzle device that is easy to assemble includes a movable component 2 comprising a nozzle 21 communicating with the outside; a valve assembly 3 comprising a valve pipe 31 communicating with the inner cavity of a container; an air outlet control structure 5 located between the nozzle 21 and the valve pipe 31; a first liquid outlet control structure 6 provided between the nozzle 21 and the valve pipe 31, capable of communicating or isolating the temporary storage chamber 4 from the inner cavity of the nozzle 21; and a second liquid outlet control structure 7 provided between the nozzle 21 and the valve pipe 31, capable of isolating the temporary storage chamber 4 from the inner cavity of the container when communicating with the inner cavity of the nozzle 21, and capable of communicating the temporary storage chamber 4 from the inner cavity of the container when isolated from the inner cavity of the nozzle 21.

[0009] As described above, a nozzle device that is easy to assemble includes a connecting structure 8 comprising a first connecting position 81 and a second connecting position 82 on a valve tube 31. The outer wall of the nozzle 21 is provided with a connecting block 83 that can cooperate with the first connecting position 81 or the second connecting position 82. When the connecting block 83 is connected to the first connecting position 81, the second air outlet window 52 is aligned with the first air outlet window 51. When the nozzle 21 slides upward relative to the base 1 for the first time, the limiting structure causes the nozzle 21 and the valve tube 31 to move relative to each other, thereby causing the connecting block 83 to separate from the first connecting position 81 and cooperate with the second connecting position 82.

[0010] As described above, a nozzle device that is easy to assemble includes a limiting block 32 provided on the valve pipe 31, and a limiting ring 11 provided on the inner wall of the base 1, which abuts against the limiting block 32 when the nozzle 21 moves upward relative to the base 1, so that the nozzle 21 and the valve pipe 31 move relative to each other.

[0011] As described above, a nozzle device that is easy to assemble is provided with a connecting plate 33 on the valve pipe 31, which is slidably and sealingly connected to the inner wall of the base 1. The temporary storage cavity 4 is formed by the lower side of the connecting plate 33, the inner cavity of the base 1, and the outer wall of the valve pipe 31.

[0012] As described above, a nozzle device that is easy to assemble is provided between the nozzle 21 and the valve tube 31. When the nozzle 21 slides downward relative to the base 1 and when the first liquid discharge control structure 6 connects the temporary storage chamber 4 with the inner cavity of the nozzle 21, the valve tube 31 can be pushed by the nozzle 21 to make it slide relative to the base 1.

[0013] As described above, a nozzle device that is easy to assemble includes a first liquid outlet control structure 6, which is provided on the valve pipe 31 and communicates with the temporary storage chamber 4, and a second liquid outlet window 62 that is aligned and communicates with the first liquid outlet window 61 on the nozzle pipe 21.

[0014] As described above, the nozzle device is easy to assemble. The second liquid discharge control structure 7 includes a first liquid discharge hole 71 provided on the valve pipe 31 and communicating with the temporary storage chamber 4. The nozzle 21 is provided with a second liquid discharge hole 72 that communicates with the inner cavity of the valve pipe 31 and can be aligned and communicated with the first liquid discharge hole 71.

[0015] As described above, a nozzle device that is easy to assemble includes a push structure 9 comprising a strip groove 91 on a valve pipe 31, and a push block 92 on the outer wall of the nozzle 21 that can enter the strip groove 91.

[0016] Compared with the prior art, the present invention has the following advantages: 1. During assembly, the present invention provides an air outlet control structure between the movable component and the valve component for controlling the connection between the sealing cavity and the outside, which facilitates the installation of the movable component onto the base, thus featuring convenient assembly and operation.

[0017] 2. This invention provides a sealing cavity on the base or movable component, and a movable part on the movable component or base that can slide and engage with the sealing cavity. In use, the movable part slides downwards relative to the base, causing the liquid in the temporary storage cavity to flow out to the outside, and isolating the temporary storage cavity from the inner cavity of the container. During the sliding of the movable component, the movable part moves upwards relative to the movable component, reducing the volume of the sealing cavity and making the air pressure inside the sealing cavity greater than the external atmospheric pressure. When the external force on the movable part is removed, the air pressure inside the sealing cavity pushes the movable part to slide upwards relative to the base to reset. During this reset process, the liquid in the inner cavity of the container enters the temporary storage cavity, which is then isolated from the outside. Therefore, this invention uses a movable part that slides and engages with the sealing cavity to create a pressure difference between the sealing cavity and the outside, replacing the complex structure of using a spring to achieve reset. Thus, this invention is characterized by its simple structure, safety, reliability, and low cost.

Detailed Implementation Methods

[0020] like Figure 1-14 As shown, the present invention provides a nozzle device that is easy to assemble, comprising a hollow base 1, a movable component 2 slidably connected to the base 1, a valve component 3 located inside the base 1 connected to the movable component 2, and a temporary storage cavity 4 formed between the valve component 3 and the base 1. When the movable component 2 slides downward relative to the base 1, the temporary storage cavity 4 is used to isolate itself from the inner cavity of the container and communicate with the outside. When the movable component 2 slides upward relative to the base 1, the temporary storage cavity 4 is used to communicate with the inner cavity of the container and isolate itself from the outside. A sealing cavity 20 is provided on the base 1 or the movable component 2, and a movable part 10 that can slide and cooperate with the sealing cavity 20 is provided on the movable component 2 or the base 1. An air outlet control structure 5 is provided between the movable component 2 and the valve component 3 to control the communication between the sealing cavity 20 and the outside and to control the isolation between the sealing cavity 20 and the outside when the movable component 2 moves relative to the valve component 3 for the first time. During assembly, this invention provides an air outlet control structure between the movable component and the valve component to control the communication between the sealing cavity and the outside. This allows the movable component to be easily installed on the base, facilitating the sliding connection between the movable component and the sealing cavity. It features convenient assembly and easy operation.

[0021] This invention features a sealed cavity on the base or movable component, with a movable part on the movable component or base that slides within the sealed cavity. In use, the movable part slides downwards relative to the base, causing liquid in the temporary storage cavity to flow out and isolating it from the container's inner cavity. During the sliding of the movable component, the movable part moves upwards relative to the movable component, reducing the volume of the sealed cavity and increasing the air pressure inside the sealed cavity to be greater than the external atmospheric pressure. When the external force on the movable part is removed, the air pressure inside the sealed cavity pushes the movable part upwards relative to the base to reset. During this reset process, liquid from the container's inner cavity enters the temporary storage cavity, which is then isolated from the outside. Therefore, this invention uses a sliding engagement between the movable part and the sealed cavity to create a pressure difference between the sealed cavity and the outside, replacing the complex structure of using a spring for reset. Thus, this invention is characterized by its simple structure, safety, reliability, and low cost.

[0022] Furthermore, the active component 2 includes a nozzle 21 communicating with the outside; the valve assembly 3 includes a valve pipe 31 for communicating with the inner cavity of the container; the gas outlet control structure 5 is located between the nozzle 21 and the valve pipe 31; a first liquid outlet control structure 6 is provided between the nozzle 21 and the valve pipe 31 to connect or isolate the temporary storage chamber 4 from the inner cavity of the nozzle 21; a second liquid outlet control structure 7 is also provided between the nozzle 21 and the valve pipe 31 to isolate the temporary storage chamber 4 from the inner cavity of the container when it is connected to the inner cavity of the nozzle 21, and to connect the temporary storage chamber 4 from the inner cavity of the container when it is isolated from the inner cavity of the nozzle 21.

[0023] Furthermore, the air outlet control structure 5 includes a first air outlet window 51 disposed on the valve pipe 31 and communicating with the sealing cavity 20, and a second air outlet window 52 disposed on the nozzle 21 that can be aligned and communicated with the first air outlet window 51 or misaligned and blocked; a connecting structure 8 is provided between the valve pipe 31 and the nozzle 21, and a limiting structure is provided between the valve pipe 31 and the base 1 that allows the valve pipe 31 and the nozzle 21 to move relative to each other when the nozzle 21 slides upward relative to the base 1 for the first time, thereby causing the second air outlet window 52 to be misaligned with the first air outlet window 51.

[0024] Furthermore, the connection structure 8 includes a first connection position 81 and a second connection position 82 provided on the valve pipe 31. The outer wall of the nozzle 21 is provided with a connecting block 83 that can cooperate with the first connection position 81 or the second connection position 82. When the connecting block 83 is connected to the first connection position 81, the second air outlet window 52 is aligned with the first air outlet window 51. When the nozzle 21 slides upward relative to the base 1 for the first time, the limiting structure causes the nozzle 21 and the valve pipe 31 to move relative to each other, thereby causing the connecting block 83 to separate from the first connection position 81 and cooperate with the second connection position 82.

[0025] Furthermore, the limiting structure includes a limiting block 32 provided on the valve pipe 31, and a limiting ring 11 provided on the inner wall of the base 1, which abuts against the limiting block 32 when the nozzle 21 moves upward relative to the base 1, so that the nozzle 21 and the valve pipe 31 move relative to each other.

[0026] Furthermore, the valve pipe 31 is provided with a connecting plate 33 that is slidably and sealingly connected to the inner wall of the base 1, and the temporary storage cavity 4 is formed by the lower side of the connecting plate 33, the inner cavity of the base 1 and the outer wall of the valve pipe 31.

[0027] Furthermore, a pusher structure 9 is provided between the nozzle 21 and the valve pipe 31, which can be pushed by the nozzle 21 to make the valve pipe 31 slide relative to the base 1 when the nozzle 21 slides downward relative to the base 1 and when the first liquid discharge control structure 6 connects the temporary storage chamber 4 with the inner cavity of the nozzle 21.

[0028] Furthermore, the first liquid discharge control structure 6 includes a first liquid discharge window 61 disposed on the valve pipe 31 and communicating with the temporary storage chamber 4, and the nozzle 21 is provided with a second liquid discharge window 62 that can be aligned and communicated with the first liquid discharge window 61.

[0029] Furthermore, the second liquid discharge control structure 7 includes a first liquid discharge hole 71 disposed on the valve pipe 31 and communicating with the temporary storage chamber 4, and the spray pipe 21 is provided with a second liquid discharge hole 72 that communicates with the inner cavity of the valve pipe 31 and can be aligned and communicated with the first liquid discharge hole 71.

[0030] Furthermore, the push structure 9 includes a strip groove 91 provided on the valve pipe 31, and a push block 92 that can enter the strip groove 91 is provided on the outer wall of the nozzle 21.

[0031] Furthermore, for smooth and convenient access, the base 1 is provided with an air inlet channel for connecting the inner cavity of the container with the outside. When the liquid in the inner cavity of the container is drawn into the temporary storage chamber 4, external gas enters the inner cavity of the container through the air inlet channel to replenish the gas.

[0032] Assembly principle: During production and assembly, the connecting block 83 on the movable part 2 is first connected to the first connecting position 81 on the valve assembly 3, which connects the valve pipe 31 to the nozzle 21. Simultaneously, the second air outlet window 52 aligns and connects with the first air outlet window 51, thus enabling the sealing cavity 20 to communicate with the outside. Figure 1 , 2 As shown, the movable part 2, together with the valve assembly 3, is then assembled onto the base 1 along the direction from the upper opening to the lower opening of the base 1. Since the sealing cavity 20 is connected to the outside, it is convenient for the movable part 10 to slide upward within the sealing cavity 20 until the upper end of the movable part 10 approaches or abuts against the bottom of the sealing cavity 20. Figure 3 , 4As shown, most of the movable part 2 is located inside the base 1, which makes the overall volume of the invention smaller, making it easier to transport, store, and package, and saving space.

[0033] In this invention, to facilitate packaging, the movable component 2 needs to be fully or partially retracted into the inner cavity of the base 1 to reduce the overall volume. However, this invention aligns and connects the second air outlet 52 with the first air outlet 51, allowing the sealed cavity 20 to communicate with the outside. This facilitates the upward sliding of the movable component 10 within the sealed cavity 20 until its upper end approaches or abuts against the inner bottom of the sealed cavity 20, thus retracting the movable component 2 into the inner cavity of the base 1. Furthermore, this invention eliminates the need for additional limiting mechanisms to restrict the movable component, and the movable component will not extend relative to the base. Compared to existing nozzle devices that use air springs or spring-reset mechanisms, which require the nozzle to be pressed into the base during packaging and then fitted with limiting mechanisms to prevent the air spring or spring from resetting, this invention features a simple structure, low cost, and reasonable design.

[0034] Furthermore, during the initial operation of the movable component 2 sliding upward relative to the base 1, the second air outlet window 52 is misaligned with the first air outlet window 51, thereby isolating the sealing cavity 20 from the outside. In subsequent operations, when the movable component 2 slides relative to the base 1, the connecting block 83 separates from the first connecting position 81 and engages with the second connecting position 82, so the second air outlet window 52 and the first air outlet window 51 cannot be realigned and connected. Therefore, the present invention has the feature of preventing counterfeiting.

[0035] Working principle: When the user uses it for the first time, they first operate the movable part 2 to slide upward relative to the base 1. Since the movable part 2 and the valve assembly 3 are connected to the first connection position 81 via the connecting block 83, the valve assembly 3 can slide upward with the movable part 2. During this sliding process, the limiting block 32 on the valve assembly 3 abuts against the limiting ring 11 on the base 1. At this time, the movable part 2 and the valve assembly 3 move relative to each other, causing the connecting block 83 to move from the first connection position 81 to the second connection position 82, and the second air outlet 52 to be misaligned with the first air outlet 51, thereby isolating the sealing cavity 20 from the outside. Figure 5 , 6 As shown; In subsequent use, the user presses the movable component 2 and slides it downward relative to the base 1, causing the connecting block 83 to abut against the second connecting position 82. At this time, the first liquid outlet window 61 and the second liquid outlet window 62 are aligned and connected, and the first liquid outlet hole 71 and the second liquid outlet hole 72 are misaligned and blocked. Simultaneously, the connecting plate 33 reduces the volume of the temporary storage chamber 4, allowing the liquid in the temporary storage chamber 4 to flow out from the first liquid outlet control structure 6 through the nozzle 21 to the outside, such as... Figure 7-10As shown; at this time, the push structure 9 is formed by the connecting block 83 and the second connecting position 82, and in the above process, the movable part 10 slides relative to the movable component 2, so that the movable part 10 can reduce the volume of the sealing cavity 20, thereby making the air pressure in the sealing cavity 20 greater than the external atmospheric pressure. When the external force applied to the movable part 2 is removed, the air pressure inside the sealing cavity 20 pushes the movable part 2 to slide upward relative to the base 1 and reset. During this reset process, the nozzle 21 slides upward relative to the base 1, while the valve pipe 31 remains stationary relative to the base 1, causing the first liquid outlet window 61 and the second liquid outlet window 62 to be misaligned and blocked, and the first liquid outlet hole 71 and the second liquid outlet hole 72 to be aligned and connected. When the push block 92 abuts against the upper end of the strip groove 91, the nozzle 21 drives the valve pipe 31 to slide upward relative to the base 1 and reset. The connecting plate 33 then moves upward, increasing the volume of the temporary storage cavity 4, thereby allowing the liquid inside the container to be drawn into the temporary storage cavity 4. Figure 11 , 12 As shown.
