[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0035] This utility model embodiment provides a dual-cavity nasal irrigator, such as... Figures 1 to 6 As shown, the dual-chamber nasal irrigator includes a nozzle 1 and a bottle body 2; the nozzle 1 includes a liquid outlet tube 11 and a connecting seat 12, the liquid outlet tube 11 is connected to the connecting seat 12, and a baffle plate 121 is provided at the bottom of the connecting seat 12; the connecting seat 12 is installed at the bottle mouth 21 of the bottle body 2, the baffle plate 121 is mated to the bottle mouth 21, and the baffle plate 121 has a liquid outlet 121a that communicates with the liquid outlet tube 11 and the bottle mouth 21.
[0036] A partition 22 is provided inside the bottle body 2, which divides the internal space of the bottle body 2 into a first liquid storage chamber 23 and a second liquid storage chamber 24, both of which are connected to the bottle opening 21. The connecting seat 12 can rotate on the bottle opening 21 to switch the liquid outlet 121a to be connected to the first liquid storage chamber 23 or the second liquid storage chamber 24.
[0037] This invention relates to a dual-chamber nasal irrigator, which uses a partition 22 to divide the bottle body 2 into a first liquid storage chamber 23 and a second liquid storage chamber 24. Both the first liquid storage chamber 23 and the second liquid storage chamber 24 are connected to the bottle opening 21. The connecting seat 12 is rotatably mounted on the bottle opening 21, and the baffle plate 121 connected to the bottle opening 21 has a liquid outlet 121a. In this way, the user can switch the connection between the liquid outlet 121a and the first liquid storage chamber 23 or the second liquid storage chamber 24 by rotating the nozzle 1. When the liquid outlet 121a is rotated to connect with the first liquid storage chamber 23, the first liquid storage chamber 23 can discharge liquid through the nozzle 1, and the second liquid storage chamber 24 is closed. When the liquid outlet 121a is rotated to connect with the second liquid storage chamber 24, the second liquid storage chamber 24 can discharge liquid through the nozzle 1, and the first liquid storage chamber 23 is closed. This allows the dual-chamber nasal irrigator to discharge liquid through a single nozzle 1, resulting in a simple structure that is conducive to low cost and miniaturization.
[0038] Specifically, the first reservoir 23 and the second reservoir 24 can respectively contain saline solution and nasal wash solution.
[0039] Furthermore, the dual-chamber nasal irrigator also includes a locking sleeve 3, which is fitted and locked onto the bottle opening 21. The connecting seat 12 is confined within the locking sleeve 3. A baffle plate 121 extends outward to form an outer edge 121b, and the locking sleeve 3 has a stepped surface 33 corresponding to the outer edge 121b, which presses against the outer edge 121b. By fitting the locking sleeve 3 onto the bottle opening 21, the installation of the connecting seat 12 on the bottle opening 21 is ensured, preventing separation of the connecting seat 12 from the bottle opening 21 due to vibration or accidental collision during use, thus improving the safety of the nasal irrigator during use. The outer edge 121b of the baffle plate 121 corresponds to the stepped surface 33 within the locking sleeve 3; this design facilitates the locking sleeve 3 in fixing the connecting seat 12 and improves the sealing performance at the bottle opening 21. The locking sleeve 3 should press against the connecting seat 12 to ensure that the nozzle 1 can rotate while maintaining stable installation.
[0040] Specifically, the locking sleeve 3 can be screwed onto the bottle mouth 21, that is, the outer circumferential surface of the bottle mouth 21 is provided with external threads, the inner circumferential surface of the locking sleeve 3 is provided with internal threads, and the locking sleeve 3 is screwed onto the bottle mouth 21 through threaded connection.
[0041] Furthermore, combined Figures 7 to 9 As shown, two gradually deepening grooves 122 extending in the circumferential direction are formed on the peripheral wall of the connecting seat 12, and the central angle of the two gradually deepening grooves 122 is 180°; the gradually deepening groove 122 has an outlet 122a at only one end, and the depth of the gradually deepening groove 122 gradually increases from one end of the outlet 122a to the other end; the inner wall of the locking sleeve 3 is provided with an installation cavity 31, and the dual-cavity nasal irrigator also includes a limiting post 4 and an elastic element 5. The elastic element 5 is installed in the installation cavity 31, and one end of the limiting post 4 is inserted into the installation cavity 31 and abuts against the elastic element 5; the installation cavity 31, the limiting post 4 and the elastic element 5 are provided in two sets corresponding to the two gradually deepening grooves 122.
[0042] When the nozzle 1 is rotated to the point where the liquid outlet 121a is connected to the first liquid storage chamber 23 or the second liquid storage chamber 24, the limiting post 4 enters the deepening groove 122 from the end of the deepening groove 122 away from the outlet 122a.
[0043] As one example, Figure 2For example, when the user rotates the nozzle 1 clockwise, the limiting post 4 enters the acuminate groove 122 from the end furthest from the outlet 122a. Because the acuminate groove 122 has a significant height difference at this end, the two limiting posts 4 will "fall" into the end of the acuminate groove 122 furthest from the outlet 122a under the elastic force of the elastic element 5, making a "click" sound. The user can then know that the liquid outlet 121a is now aligned and connected with the first liquid storage chamber 23. Furthermore, because the limiting post 4 is blocked by the end of the acuminate groove 122 furthest from the outlet 122a, the nozzle 1 cannot rotate counterclockwise. Continuing to rotate nozzle 1 clockwise, the two limiting posts 4 exit from their respective deepening grooves 122 through outlets 122a. After rotating 180°, the limiting posts 4 re-enter the other deepening groove 122 from the end furthest from outlet 122a, producing a "click" sound. This indicates to the user that the liquid outlet 121a is now aligned and connected to the second liquid storage chamber 24, thus completing the connection switching between the liquid outlet 121a and the first and second liquid storage chambers 23 and 24. Continuing to rotate nozzle 1 clockwise repeats the above process, continuously switching the connection between the liquid outlet 121a and the first and second liquid storage chambers 23 and 24. In this example, if nozzle 1 is rotated counterclockwise, the limiting posts 4 will be blocked by the end of the deepening groove 122 furthest from outlet 122a, preventing continuous counterclockwise rotation and avoiding misoperation.
[0044] Of course, the above example is only an example of the clockwise rotation scheme of nozzle 1. In other examples, the depth of the gradual groove 122 can also be set in the opposite direction, that is, the outlet 122a of the gradual groove 122 is set at the other end. In this case, when switching between the liquid outlet 121a and the first liquid storage chamber 23 and the second liquid storage chamber 24, the nozzle 1 is rotated counterclockwise.
[0045] Specifically, the elastic element 5 is a spring, which provides the elastic force to push the limiting post 4, so that the limiting post 4 can abut against the peripheral wall of the connecting seat 12, ensuring that the limiting post 4 can be embedded in the progressive groove 122.
[0046] The mounting cavity 31 extends radially through the locking sleeve 3, and a sealing plug 32 is installed at its outer end. The radial extension of the locking sleeve 3 through the mounting cavity 31 facilitates the assembly of the elastic element 5 and the limiting post 4 into the mounting cavity 31 from the outside of the connecting seat 12. The outer end of the mounting cavity 31 is further sealed by the sealing plug 32. The sealing plug 32 can be glued to the mounting cavity.
[0047] The liquid outlet 121a is located on the same side as the outlet 111 of the liquid outlet pipe 11. In this way, the first liquid storage chamber 23 or the second liquid storage chamber 24, which is on the same side as the outlet 111 of the liquid outlet pipe 11, is the cavity that communicates with the liquid outlet 121a for liquid discharge. The user can determine whether the liquid outlet 121a is currently connected to the first liquid storage chamber 23 or the second liquid storage chamber 24 by the orientation of the outlet 111 of the liquid outlet pipe 11.
[0048] Furthermore, the dual-chamber nasal irrigator also includes a sealing ring 6, which is installed between the edge of the bottle opening 21 and the outer edge 121b. The sealing ring 6 can further improve the sealing performance at the bottle opening 21. The sealing ring 6 can be a rubber ring, etc. A limiting edge 61 is provided in the sealing ring 6, and a retaining groove 611 is provided on the side of the limiting edge 61 facing inward of the bottle body 2. The top edge of the partition 22 is retained in the retaining groove 611. Through the limiting cooperation between the retaining groove 611 and the top edge of the partition 22, the installation stability of the sealing ring 6 can be improved, preventing the sealing ring 6 from rotating with the connecting seat 12.
[0049] like Figure 1 , Figure 11 and Figure 12 As shown, each of the first and second liquid storage chambers 24 on the bottle body 2 is equipped with a vent switch 7. By controlling the vent switch 7, the first and second liquid storage chambers 23 and 24 can be connected to the outside. By controlling the vent switch 7, the air pressure of the first and second liquid storage chambers 23 and 24 can be balanced with the outside air pressure, thereby increasing the liquid outflow rate from the first and second liquid storage chambers 23 and 24.
[0050] Specifically, the bottle body 2 is provided with a hollow mounting ring 25, and the vent switch 7 includes a pressing element 71, a vent element 72, and a first spring 73. One end of the vent element 72 is limited inside the mounting ring 25, and the other end passes through the mounting ring 25 and connects to the pressing element 71; the pressing element 71 is sleeved on the vent element 72, and the first spring 73 is sleeved on the vent element 72 and abuts against the mounting ring 25 and the pressing element 71 respectively; a first vent groove 721 extending axially along the peripheral wall of the vent element 72 is provided, and pressing the pressing element 71 connects the first liquid storage chamber 23 and the second liquid storage chamber 24 to the outside through the first vent groove 721. A limiting ring 722 is provided around the end of the vent element 72 located inside the mounting ring 25, and a sealing ring 74 is sleeved on the vent element 72, with the sealing ring 74 located between the limiting ring 722 and the mounting ring 25. In the initial state, under the elastic force of the spring, the vent 72 is pushed towards the outside of the bottle 2, thereby causing the limiting ring 722 to press against the sealing ring 74, ensuring the sealing of the first liquid storage chamber 23 and the second liquid storage chamber 24, and preventing leakage of the liquid inside. During use, the operator inverts the nasal irrigator and presses the pressing member 71. The pressing member 71 pushes the vent 72 to retract into the bottle 2, and the first vent groove 721 connects the first liquid storage chamber 23 and the second liquid storage chamber 24 to the outside, balancing the air pressure inside and outside the bottle 2.
[0051] Furthermore, a second venting groove 711 extending axially along the periphery of the pressing member 71 is provided, making it easier for outside air to enter the bottle body 2. Specifically, the mounting ring 25 is located near the bottom of the bottle body 2, and the venting switch 7 can be installed near the bottom of the bottle body 2.
[0052] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
