A nasal irrigation device and nasal irrigation kit

Abstract

A nasal irrigation device and kit include a valve body, which has a water outlet channel, a material chamber connected to the water outlet channel, and a feeding port connected to the material chamber. A front housing is provided around the valve body and is movable relative to the valve body. During use, the front housing has at least a first state and a second state along its movement path. When the user drives the front housing to the first state, the feeding port is hidden inside the front housing and is not visible to the user. When the user drives the front housing to the second state, the feeding port is revealed and is within the user's visible range. Therefore, the user can quickly switch between the first and second states by driving the front housing, thus keeping the feeding port hidden or revealed, ensuring that the feeding port is only visible to the user during the feeding process, improving the overall appearance of the nasal irrigation device.

Description

Technical Field

[0001] This invention relates to the field of nasal cleaning devices, and more particularly to a nasal rinsing device and nasal rinsing kit. Background Technology

[0002] A nasal irrigator is a tool used to clean the nasal cavity, removing allergens, dust, bacteria, and other tiny particles through gentle rinsing. Users add saline solution through the filling port or add nasal saline directly. However, the filling port on most nasal irrigators is typically exposed, meaning it remains visible during both nasal irrigation and filling processes. This unsightly design disrupts the overall aesthetics of the nasal irrigator. Summary of the Invention

[0003] The purpose of this invention is to provide a nasal irrigation device and nasal irrigation kit, which aims to overcome the problem of inconvenient opening of the housing in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A nasal irrigation device includes a valve body, one end of which is provided with a water outlet channel and a material chamber communicating with the water outlet channel, and the valve body is provided with a feeding port communicating with the material chamber; the valve body is covered with a front shell that is movable relative to the valve body, and the front shell has at least a first state and a second state on its movement path;

[0006] When the front housing is in the first state, the feeding port is hidden inside the front housing; when the front housing is in the second state, the feeding port is exposed.

[0007] Furthermore, the second state includes a second state A and a second state B; when the front housing is in the second state A, the feed port is visible and the front housing is movably connected to the valve body; when the front housing is in the second state B, the front housing is detached from the valve body.

[0008] Furthermore, a limiting mechanism is provided between the front housing and the valve body, allowing the front housing to move along a preset path, with positions respectively provided on the preset path for realizing the first state, the second state A, and the second state B.

[0009] Furthermore, the limiting mechanism includes a boss provided on the inner wall of the front housing and a guide groove provided on the surface of the valve body and adapted to the boss. The guide groove includes a first groove segment and a second groove segment. The first groove segment extends from near the feed port to away from the feed port. One end of the second groove segment is connected to the first groove segment and the other end extends away from the feed port. The other end of the second groove segment passes through the end face of the valve body.

[0010] When the boss is located at the end of the first groove near the feed port, the front housing is in the first state; when the boss is located at the end of the first groove away from the feed port, the front housing is in the second state A; when the boss is separated from the valve body through the second groove, the front housing is in the second state B.

[0011] Furthermore, the guide groove also includes an anti-detachment section, which is arranged circumferentially along the valve body. One end of the anti-detachment section is connected to the end of the first groove near the feed port. When the boss is located in the anti-detachment section, the front housing is in the first state.

[0012] Furthermore, it also includes a first elastic element, one end of which abuts against the valve body, and the other end of which abuts against the front housing. When the boss is located in the first groove, the boss moves to the end of the first groove away from the feed port under the elastic force of the first elastic element, so that the front housing is in the second state A; or, when the boss is located in the second groove, the boss disengages from the valve body from the other end of the second groove under the elastic force of the first elastic element, so that the front housing is in the second state B.

[0013] Furthermore, it includes a nozzle tube, one end of which is movably and sealed to fit into the water outlet channel, and the other end of which has a water outlet. The front housing is connected to the middle of the nozzle tube, so that the nozzle tube moves with the front housing.

[0014] Furthermore, the water outlet is a flexible water outlet connector.

[0015] Furthermore, it also includes a conduit, which is disposed on one side of the valve body, the flow channel inside the conduit forms the water outlet channel, and the side wall of the conduit is provided with a connecting hole that connects the material chamber and the water outlet channel.

[0016] Furthermore, the valve body is provided with a flow chamber, the water outlet channel is connected to the flow chamber, and a movable tube that is movable relative to the valve body is provided on the other side of the valve body. The movable tube is provided with a flow channel and has a first position that closes the flow channel and the flow chamber and a second position that connects the flow channel and the flow chamber.

[0017] Furthermore, the flow cavity is provided with an abutment member. When the moving tube is sealed against the abutment member, the moving tube is in the first position; when the moving tube is disengaged from the abutment member, the moving tube is in the second position.

[0018] Furthermore, it also includes a second elastic element, one end of which abuts against the valve body, and the other end of which abuts against the moving tube, the moving tube being in the first position under the elastic force of the second elastic element.

[0019] Furthermore, the valve body is provided with a driving member, which is throttle-connected to the moving tube, and the moving tube is driven to the second position by pushing the driving member.

[0020] A nasal irrigation kit includes the nasal irrigation device as described above, and also includes a thermostatic valve, which has a cold water inlet, a hot water inlet and a mixed water outlet, the mixed water outlet being connected to the water inlet of the valve body.

[0021] The beneficial effects of this invention are:

[0022] 1. The present invention proposes a nasal irrigation device, comprising a valve body, the valve body having a water outlet channel, a material chamber connected to the water outlet channel, and a feeding port connected to the material chamber; the valve body is covered with a front shell that is movable relative to the valve body. In use, the front shell has at least a first state and a second state on its movement path. When the user drives the front shell to the first state, the feeding port is hidden inside the front shell and is not visible to the user; when the user drives the front shell to the second state, the feeding port is revealed and is within the user's visible range. Therefore, the user can quickly switch between the first and second states by driving the front shell, thereby making the feeding port either hidden or revealed, so that the feeding port is only within the user's visible range during the feeding process, improving the overall appearance of the nasal irrigation device.

[0023] 2. The nasal irrigation device proposed in this invention has two states: a second state A and a second state B. When the front housing is in the second state A, the front housing is movably connected to the valve body, allowing the user to add salt to the feeding chamber through the feeding port without completely disassembling the front housing. This reduces the possibility of the front housing being lost due to careless placement and prevents contamination of the front housing. When the front housing is in the second state B, the front housing is detached from the valve body, suitable for situations where the valve body needs to be replaced or repaired. With the feeding port visible, the front housing also has two different states to meet the user's needs for the front housing's operating state under different usage conditions.

[0024] 3. The nasal irrigation device proposed in this invention has a limiting mechanism between the front housing and the valve body, which guides the user to drive the front housing on a preset path, so that the front housing moves on the preset path, thereby realizing the first state, the second state A and the second state B respectively.

[0025] 4. The nasal irrigation device proposed in this invention includes a limiting mechanism comprising a first groove segment and a second groove segment for realizing the second state A and the second state B of the front housing, respectively. When the boss is located at the end of the first groove segment near the feeding port, the boss moves quickly to the end of the first groove segment away from the feeding port under the elastic force of the first elastic element, so that the user can add material to the material chamber through the feeding port when the front housing is not completely disassembled, thereby improving the user experience.

[0026] 5. The present invention proposes a nasal irrigation device, including a catheter, the flow channel of the catheter forming a water outlet channel, and a connecting hole on the side wall of the catheter connecting the material chamber and the water outlet channel. Part of the water flows into the material chamber through the connecting hole to initially dissolve the salt. At the same time, a vortex is generated at the connecting hole to draw out the salt solution in the material chamber. The salt that has not been completely dissolved in the salt solution is impacted by the vortex to accelerate the dissolution of the salt block, thereby increasing the salt concentration in the nasal irrigation solution and reducing the number of times salt is added.

[0027] 6. The nasal irrigation device proposed in this invention further includes a movable tube, which has a first position that abuts against a seal to block the communication between the flow channel and the flow cavity, and a second position that disengages from the seal to allow the flow channel to connect with the flow cavity, so that the user can pause and supply nasal irrigation fluid by driving the movable tube.

Detailed Implementation

[0041] Example 1

[0042] Combination Figures 1 to 9 This embodiment will be described in detail.

[0043] This embodiment proposes a nasal irrigation device, including a valve body 20. One end of the valve body 20 is provided with a water outlet channel 902 and a material chamber 201 communicating with the water outlet channel 902. The valve body 20 is provided with a feeding port 2011 communicating with the material chamber 201. A front housing 50 is provided around the valve body 20 and is movable relative to the valve body 20. The front housing 50 has at least a first state and a second state on its movement path. When the front housing 50 is in the first state, the feeding port 2011 is hidden inside the front housing 50. At this time, the outer contours of the valve body 20 and the front housing 50 are flush, resulting in a high degree of appearance integrity and aesthetics. Figure 1As shown; when the current housing 50 is in the second state, the feed port 2011 is displayed, as shown. Figure 2 As shown.

[0044] Therefore, during use, the user can quickly and easily hide or reveal the feeding port 2011 by driving the front housing 50 to either the first or second state. The user then adds an appropriate amount of the special nasal irrigation salt into the material chamber 201 through the feeding port 2011, achieving convenient operation. In addition, the design of the hidden feeding port 2011 maintains the overall appearance of the nasal irrigation device 10, reduces the abruptness caused by the feeding port 2011, and improves the user's visual experience.

[0045] In this embodiment, the second state includes second state A and second state B; when the current housing 50 is in second state A, the feed port 2011 is visible, and the front housing 50 is movably connected to the valve body 20, such as... Figure 2 As shown, this reduces the possibility of losing the front housing 50 due to careless placement. When the front housing 50 is in the second state B, the front housing 50 is detached from the valve body 20, as... Figure 3 As shown. During use, since the salt in the material chamber 201 is almost depleted, it is necessary to replenish the salt as much as possible. At this time, the front housing 50 does not need to be detached from the valve body 20; only the feeding port 2011 needs to be exposed. In this case, the front housing 50 is in the second state A. However, when the valve body 20 needs to replace parts, for ease of operation, the front housing 50 needs to be removed and detached from the valve body 20. In this case, the front housing 50 is in the second state B. Therefore, with the feeding port 2011 exposed, the front housing 50 has two different states to meet the user's needs for the working state of the front housing 50 under different operating conditions.

[0046] In this embodiment, a limiting mechanism is provided between the front housing 50 and the valve body 20 to guide the user to drive the front housing 50 on a preset path, so that the front housing 50 moves on the preset path. The preset path is provided with positions for realizing the first state, the second state A and the second state B respectively.

[0047] In this embodiment, the limiting mechanism includes a boss 501 on the inner wall of the front housing 50 and a guide groove on the surface of the valve body 20 that is adapted to one end of the front housing 50. The boss 501 and the guide groove are adapted to each other. The guide groove includes a first groove segment 2021 and a second groove segment 2022. The first groove segment 2021 extends from near the feed port 2011 to away from the feed port 2011. One end of the second groove segment 2022 is connected to the middle of the first groove segment 2021 through a connecting groove segment 2024, and the other end of the second groove segment 2022 extends away from the feed port 2011. The other end of the second groove segment 2022 passes through the end face of the valve body 20. Figure 3 As shown.

[0048] In this embodiment, the guide groove also includes an anti-detachment section 2023, which is arranged circumferentially along the valve body 20. One end of the anti-detachment section 2023 is connected to the end of the first groove section 2021 near the feed port 2011. When the boss 501 is located in the anti-detachment section 2023, the front housing 50 is in the first state.

[0049] In this embodiment, a first elastic element 1101 is also included, which is usually a compression spring. One end of the first elastic element 1101 abuts against the valve body 20, and the other end of the first elastic element 1101 abuts against the front housing 50. Furthermore, the valve body 20 is provided with an abutting surface for abutting against one end of the first elastic element 1101, and the inner side of the front housing 50 is provided with a limiting groove 502 for abutting against the other end of the first elastic element 1101.

[0050] In this embodiment, when the salt in the material chamber 201 is sufficient and the user is using the nasal irrigation device normally, the boss 501 is located in the anti-detachment groove section 2023, the first elastic element 1101 is in a compressed state, and the front housing 50 is pressed against the valve body 20. When the salt in the material chamber 201 is insufficient and the feeding port 2011 needs to be exposed for feeding, compared to the need to continuously rotate the housing when using a threaded connection, the user only needs to rotate the front housing 50 so that the boss 501 enters the first groove section 2021 from the anti-detachment groove section 2023 and enters the end of the first groove section 2021 near the feeding port 2011. The elastic force generated by the reset of the first elastic element 1101 pushes the boss 501 to slide quickly to the end of the first groove section 2021 away from the feeding port 2011, so that the housing is in the second state. In state A, the feeding port 2011 is visible, preventing the user from continuously rotating it to disassemble the housing. It also allows the user to add material to the material chamber 201 through the feeding port 2011 even when the front housing 50 is not completely disassembled, reducing the possibility of the front housing 50 being lost. When the front housing 50 needs to be completely disassembled due to malfunction or other issues, the user drives the front housing 50 to move the boss 501 to the port of the connecting groove 2024 connected to the first groove 2021. Then, the boss 501 slides into the second groove 2022 through the connecting groove 2024. The boss 501 is then separated from the valve body 20 through the second groove 2022, and at the same time, the front housing 50 is completely disassembled from the valve body 20, i.e., the front housing 50 is in state B.

[0051] In this embodiment, a sealing cap 80 is also included, which is used to cover the feed port 2011.

[0052] In this embodiment, a nozzle tube 60 is also included. One end of the nozzle tube 60 is movably sealed and adapted to the water outlet channel 902, and the other end of the nozzle tube 60 has a water outlet. The middle part of the nozzle tube 60 is connected to the side of the front housing away from the feed port 2011, so that the nozzle tube 60 moves with the front housing 50. Specifically, rotating the front housing 50 causes the boss 501 to enter the first groove section 2021 from the anti-detachment groove section 2023, and the nozzle pipe 60 rotates with the front housing 50. Under the elastic force of the first elastic element 1101, the boss 501 moves to the end of the first groove section 2021 away from the feed port 2011, and the nozzle pipe 60 moves with the front housing 50 in the direction away from the feed port 2011. At this time, one end of the nozzle pipe 60 is still sealed and adapted to the guide tube 90. When the boss 501 disengages from the valve body 20 through the second groove section 2022, the front housing 50 disengages from the valve body 20, and at the same time, the nozzle pipe 60 disengages from the guide tube 90.

[0053] In this embodiment, the water outlet is a flexible connector, specifically a silicone head 70. The soft texture of the silicone head 70 enhances the comfort of the nasal irrigation device when in contact with the user's nasal cavity.

[0054] In this embodiment, a conduit 90 is also included. The conduit 90 is disposed on one side inside the valve body 20. The flow channel inside the conduit 90 forms a water outlet channel 902. The space between the outer wall of the conduit 90 and the inner wall of the valve body 20 forms a material cavity 201. The side wall of the conduit 90 is provided with a connecting hole 901 that connects the material cavity 201 and the water outlet channel 902. In other embodiments, the material cavity 201 may also be separately disposed in the valve body 20. During use, part of the water flows into the material cavity 201 through the connecting hole 901 to initially dissolve the salt. At the same time, a vortex is generated at the connecting hole 901 to draw out the salt solution in the material cavity 201. The salt that has not been completely dissolved in the salt solution is impacted by the vortex, thereby accelerating its dissolution, increasing the salt concentration in the nasal irrigation solution, and reducing the number of times salt needs to be added.

[0055] In this embodiment, the front housing 50 has an inner cavity extending through its axis. A threaded hole is provided at one opening of the inner cavity, and this threaded hole is threaded to fit the middle of the nozzle tube 60, allowing the nozzle tube 60 to move with the front housing 50. In other embodiments, the connection between the front housing 50 and the nozzle tube 60 can also be a snap-fit, magnetic, or other connection method. The other opening of the inner cavity is adapted to the side of the valve body 20 where a guide groove is provided, allowing the valve body 20 to be inserted into the front housing 50 through the other opening of the inner cavity. Furthermore, two bosses 501 are provided at or near the other opening of the inner cavity on the inner cavity sidewall, with the two bosses 501 positioned opposite each other on the inner cavity wall of the front housing 50. Guide grooves are provided on opposite sides of the valve body 20 surface, with the two bosses 501 fitting into the corresponding guide grooves, ensuring that the front housing 50 is evenly stressed during movement.

[0056] In this embodiment, a flow passage 203 is provided in the middle of the valve body 20, and the water outlet channel 902 is connected to the flow passage 203. On the other side inside the valve body 20, a movable tube 100 is provided relative to the valve body 20. The movable tube 100 is provided with a flow passage 1001, and the movable tube 100 has a first position where the flow passage 1001 and the flow passage 203 are closed (e.g., ...). Figure 7 (as shown) and the second position connecting the flow channel 1001 and the flow cavity 203 (as shown) Figure 8 (As described above). Users can pause and resume the supply of nasal irrigation solution by driving the moving tube 100 according to their needs.

[0057] In this embodiment, the flow cavity 203 is provided with an abutment. When the moving tube 100 is sealed against the abutment, the moving tube 100 is in a first position; when the moving tube 100 is disengaged from the abutment, the moving tube 100 is in a second position. Further, the flow cavity 203 is provided with a positioning post 2031, which constitutes the abutment. A sealing member 30 is fitted over the positioning post 2031. When the moving tube 100 is in the first position, the moving tube 100 is sealed against the sealing member 30; when the moving tube 100 is in the second position, the moving tube 100 is disengaged from the sealing member 30. In other embodiments, the sealing member 30 may also be located at the end of the moving tube 100 facing the abutment, so that when the moving tube 100 is in the first position, the moving tube 100 is sealed against the sealing member 30.

[0058] In this embodiment, a top cover 40 is also included for covering the flow cavity 203. The top cover 40 is used to seal the opening of the flow cavity 203 on the one hand, and to press the sealing member 30 on the other hand.

[0059] In this embodiment, a second elastic element 1102 is also included, which is usually a compression spring. One end of the second elastic element 1102 abuts against the valve body 20, and the other end of the second elastic element 1102 abuts against the moving tube 100. The moving tube 100 is in the first position under the elastic force of the second elastic element 1102.

[0060] In this embodiment, the valve body 20 is provided with a driving member 120, which is tractively connected to the moving tube 100. Pushing the driving member 120 drives the moving tube 100 to the second position. Specifically, the driving member 120 is a button, one end of which is pivotally connected to the valve body 20, and the other end of which has a first abutting portion 1801 extending into the moving tube 100. The outer wall of the moving tube 100 has a second abutting portion 1802 extending into the driving member 120. Pressing the driving member 120 causes its other end to swing, causing the first abutting portion 1801 to push against the second abutting portion 1802, thereby driving the moving tube 100 to the second position. Releasing the driving member 120 causes the moving tube 100 to move to the first position under the elastic force of the second elastic member 1102. In other embodiments, the drive member 120 may also be a slider slidably connected to the valve body 20. The slider and the moving tube 100 are provided with a first abutting part 1801 and a second abutting part 1802 as described above. By pushing the slider, the first abutting part 1801 pushes against the second abutting part 1802, thereby driving the moving tube 100 to move to the second position.

[0061] In this embodiment, a rear housing 130 is also included. The front housing 50 is sleeved on one side of the valve body 20, and the rear housing 130 is sleeved on the other side of the valve body 20. The side of the rear housing 130 is provided with a through hole 1301 for the drive member 120 to pass through.

[0062] In this embodiment, a water inlet connector 140 is also included. The water inlet connector 140 has a water inlet channel. One end of the water inlet connector 140 is located inside the valve body 20, and the end of the moving pipe 100 away from the sealing element 30 is movably sealed inside the water inlet channel. The other end of the water inlet connector 140 is located outside the valve body 20, and the other end of the water inlet connector 140 passes through the rear housing 130 and has a connector for connecting the water inlet pipe. The water inlet end of the connector constitutes the water inlet of the valve body 20. A locking cover 150 is also connected to the end of the water inlet connector 140 outside the valve body 20. The locking cover 150 has a pressing surface adapted to the connector for pressing the water inlet pipe to the water inlet connector 140. The rear housing 130 has an abutment surface. By rotating the locking cover 150 to abut against the abutment surface of the rear housing 130, the rear housing 130 is locked onto the valve body 20.
