Description

Technical Field

[0001] This utility model relates to the field of nasal spray technology, specifically to a nozzle structure for a nasal spray. Background Technology

[0002] Nasal sprays are common nasal cleaning tools. To enable nasal sprays to adjust the flow rate of the cleaning solution, making them suitable for different users, patent application number CN202223175015.0 discloses a tool for nasal cleaning. This technology uses a rotating operating shaft, which, through a first and second bevel gear, causes the transmission shaft and the opening / closing plate to rotate and rotate, thus opening and closing the plate. It also allows users to freely select the flow rate according to their needs, making it suitable for different users. However, the adjustment mechanism in this technology is relatively complex, requiring transmission between gears and rotating shafts, which reduces the stability of use. Utility Model Content

[0003] To address the aforementioned issues, this application provides a nozzle structure for a nasal sprayer that is simple in structure and capable of adjusting the flow rate of the cleaning fluid.

[0004] The objective of this utility model is achieved through the following technical solution: the nozzle structure of the nasal sprayer includes:

[0005] Nozzle;

[0006] The nozzle is axially movable and mounted at the end of the nozzle pipe, and has a spray hole that communicates with the nozzle pipe.

[0007] A blocking mechanism is disposed inside the nozzle to block the nozzle orifice; when the nozzle moves axially along the nozzle, the opening of the nozzle orifice can be adjusted.

[0008] Furthermore, the blocking mechanism includes a conical plug, which is fixed inside the nozzle by a fixing rod; when the nozzle moves axially along the nozzle, the depth of the plug inserted into the nozzle orifice can be adjusted to adjust the opening of the nozzle orifice, thereby realizing the flow rate regulation of the cleaning fluid.

[0009] As a preferred embodiment, the plug is provided with a conical guide platform, the tip of which faces away from the nozzle. By providing the guide platform, the cleaning fluid is directed to the surrounding area, mitigating the impact of the cleaning fluid on the clogging mechanism.

[0010] As a preferred embodiment, the nozzle and the nozzle pipe are connected by a thread to facilitate adjustment of the nozzle position, thereby adjusting the opening of the nozzle orifice.

[0011] As a preferred embodiment, the nozzle connection end is provided with an annular connection bayonet, and the nozzle connection end is movably connected within the annular connection bayonet.

[0012] As a preferred embodiment, a seal is connected between the bottom of the annular connecting bayonet and the end of the nozzle, forming a seal between the nozzle and the nozzle to prevent cleaning fluid from leaking out from the connection point.

[0013] Furthermore, the sealing element includes a sealing gasket; at least one side of the sealing gasket is connected to an arc-shaped elastic sheet, and an adjustment cavity is formed between the elastic sheet and the sealing gasket.

[0014] Both sides of the sealing gasket are connected to elastic sheets.

[0015] The elastic sheet is elastic and forms an adjustment cavity with the sealing gasket. When the nozzle moves, the elastic sheet can always fit tightly against the bottom of the annular connecting jaw and the end of the nozzle, so that the nozzle and the nozzle always remain sealed.

[0016] The nozzle's connecting end and the annular connecting bayonet are connected by a thread to facilitate adjustment of the nozzle's position.

[0017] Compared with the prior art, this application has the following beneficial effects:

[0018] (1) This utility model can adjust the depth of the plug inserted into the nozzle by adjusting the position of the nozzle, thereby adjusting the opening of the nozzle and realizing the flow rate regulation of the cleaning fluid. It has a simple structure and is easy to operate.

[0019] (2) The present invention is provided with a flow guide platform, which can guide the cleaning fluid to the surrounding area and reduce the impact of the cleaning fluid on the clogging mechanism.

[0020] (3) The present invention provides a sealing element between the bottom of the nozzle and the annular connecting bayonet. The sealing element is provided with an elastic sheet. When the nozzle moves, the elastic sheet can always be in close contact with the bottom of the annular connecting bayonet and the end of the nozzle, so that the nozzle and the nozzle are always sealed.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0029] Example 1

[0030] like Figure 1 As shown in the figure, this embodiment discloses a nasal spray nozzle structure, which includes: a nozzle 1, a nozzle 2, and a blocking mechanism 3. The nozzle 2 is installed at the end of the nozzle 1 and is movable along the axial direction of the nozzle 1. The nozzle 2 has a spray hole 4 communicating with the nozzle 1. In use, the cleaning fluid flows along the nozzle 1 and is sprayed out from the spray hole 4 on the nozzle 2. Specifically, the nozzle 2 and the nozzle 1 can be connected by a thread, and the position of the nozzle 2 can be easily adjusted by turning it.

[0031] The blocking mechanism 3 is located inside the nozzle 1 and is used to block the nozzle 4. When the nozzle 2 moves along the axial direction of the nozzle 1, the position between the nozzle 2 and the blocking mechanism 3 can be adjusted, thereby adjusting the opening of the nozzle 4.

[0032] Specifically, such as Figure 1 , 4As shown, the blocking mechanism 3 includes a plug 31, which is fixed inside the nozzle 1 by a fixing rod 32. The plug 31 is conical, with its tip facing the nozzle 4 and corresponding to the position of the nozzle 4. When the nozzle 2 is turned to move towards the nozzle 1, the nozzle 2 gradually approaches the plug 31, causing the plug 31 to insert into the nozzle 4. The opening of the nozzle 4 decreases, and the flow rate of the cleaning fluid decreases. When the nozzle 2 moves away from the nozzle 1, the plug 31 gradually exits the nozzle 4, and the opening of the nozzle 4 gradually increases, increasing the flow rate of the cleaning fluid. This allows for the adjustment of the cleaning fluid flow rate. The structure is simple, and the operation is convenient and stable.

[0033] Example 2

[0034] This embodiment is basically the same as embodiment 1, except that the plug 31 in this embodiment is provided with a conical guide platform 33. The tip of the guide platform 33 faces away from the nozzle 2, that is, the tip of the guide platform 33 faces the direction of the cleaning fluid flow. In this way, the guide platform 33 can guide the cleaning fluid to the surrounding area and reduce the impact of the cleaning fluid on the clogging mechanism 3.

[0035] Example 3

[0036] like Figure 2 As shown, in this embodiment, based on embodiment 1 or 2, the connecting end of the nozzle 2 is provided with an annular connecting slot 5, and the connecting end of the spray pipe 1 is movably connected within the annular connecting slot 5. Alternatively, the connecting end of the nozzle 2 and the annular connecting slot 5 can be configured as a threaded connection to facilitate adjustment of the nozzle 2's position.

[0037] In addition, a sealing element 6 is connected between the bottom of the annular connecting bayonet 5 and the end of the nozzle 1. The sealing element 6 forms a seal between the nozzle 2 and the nozzle 1 to prevent the cleaning fluid from leaking out from the connection between the two.

[0038] Specifically, such as Figure 3 As shown, the seal 6 includes a sealing gasket 61, at least one side of which is connected to an arc-shaped elastic sheet 62, and an adjustment cavity 63 is formed between the elastic sheet 62 and the sealing gasket 61. In this embodiment, elastic sheets 62 are connected to both sides of the sealing gasket 61.

[0039] Two elastic plates 62 are in contact with the bottom of the annular connecting slot 5 and the end of the nozzle 1, respectively. When the nozzle 2 is turned so that the nozzle 1 moves into the annular connecting slot 5, that is, the opening of the nozzle 4 is reduced, the two elastic plates 62 are squeezed and the adjusting cavity 63 becomes smaller. When the nozzle 1 moves out of the annular connecting slot 5, that is, the opening of the nozzle 4 is increased, the two elastic plates 62 gradually return to their original shape and the adjusting cavity 63 becomes larger. During this process, the two elastic plates 62 can always be tightly attached to the bottom of the annular connecting slot 5 and the end of the nozzle 1, so that the nozzle 2 and the nozzle 1 are always sealed.

[0040] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0041] Furthermore, the specific embodiments described above are exemplary.
