[0047] The present utility model discloses a nasal cavity cleaning device, which can avoid the situation that liquid drips onto the body and causes the body to be soiled, and the user experience is better.

[0048] Please refer to Figure 1 and Figure 2, which is a schematic structural diagram of a nasal cavity cleaning device 100 provided by an embodiment of the present invention. The nasal cavity cleaning device 100 includes a body 10 and a nozzle 20. A liquid pumping assembly 30 is arranged inside the body 10. The nozzle 20 has a water inlet 20a and a water outlet 20b that are in communication with each other. The nozzle 20 is connected to the body 10, and the water inlet 20a is in communication with the liquid pumping assembly 30. The water outlet 20b is used for the liquid pumped into the nozzle 20 to flow out.

[0049] As Figure 3 shown, when the body 10 is in a first posture in at least one direction, at least a part of the projection of the water outlet 20b on the horizontal plane β is located outside the projection of the body 10 on the horizontal plane β. The first posture is a posture in which the height direction x of the body 10 forms an angle α with the vertical direction p, and 0° ≤ α ≤ 30°.

[0050] Figure 3 The dotted line in

[0051] represents the horizontal plane β, and the dashed line represents the projections of the water outlet 20b and the body 10 on the horizontal plane β. Optionally, the angle α can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, etc.

[0052] Among them, the first posture is a posture in which the height direction x of the body 10 forms an angle α with the vertical direction p, that is, the body 10 is tilted by an angle α from the posture where the height direction x is parallel to the vertical direction p, thereby forming the first posture. It can be understood that the body 10 can be tilted in any direction perpendicular to the height direction x of the body, and any direction includes any one of the 360° directions.

[0053] In this embodiment, a liquid pumping assembly 30 is arranged inside the body 10. The nozzle 20 is connected to the body 10, and the water inlet 20a of the nozzle 20 is communicated with the liquid pumping assembly 30. The liquid pumping assembly 30 can pump the liquid into the nozzle 20 through the water inlet 20a, and the liquid pumped into the nozzle 20 can flow out from the water outlet 20b of the nozzle 20, so as to enable the user to wash the nasal cavity. Meanwhile, when the body 10 is in the first posture in at least one direction, at least a part of the projection of the water outlet 20b on the horizontal plane β is located outside the projection of the body 10 on the horizontal plane β. In this way, when the user uses the nasal cavity cleaning device 100 to wash the nasal cavity, by tilting the body 10 by less than 30° in at least one direction, that is, making the included angle between the height direction x of the body 10 and the vertical direction p be the included angle α, when the liquid drips along the vertical direction p under the action of gravity, it can avoid the body 10, thereby avoiding the situation that the liquid drips onto the body 10 and causes the body 10 to be soiled, and the user experience is better.

[0054] Wherein, the vertical direction p is perpendicular to the horizontal plane β. When the user uses the nasal cavity cleaning device 100 to wash the nasal cavity, the body 10 is usually held by hand. And in order to make the nozzle 20 match and fit with the user's nasal cavity and the water outlet 20b be aligned with the nasal cavity to flow out the liquid, it is necessary to tilt the body 10 by a certain angle, that is, the included angle between the height direction x of the body 10 and the vertical direction p is a certain angle, and this angle can be the included angle α. In some other embodiments, this angle can also be greater than 30°.

[0055] In some embodiments, as Figure 4 shown, at least a part of the projection of the water outlet 20b on the first plane γ is located outside the projection of the body 10 on the first plane γ, and the first plane γ is perpendicular to the height direction x of the body 10. In this way, on the one hand, by making at least a part of the projection of the water outlet 20b on the first plane γ be located outside the projection of the body 10 on the first plane γ, when the body 10 is tilted by a certain angle so that the included angle between the height direction x of the body 10 and the vertical direction p is the included angle α, the distance between the water outlet 20b and the body 10 along the inclined direction increases, then it can be ensured that at least a part of the projection of the water outlet 20b on the horizontal plane β is located outside the projection of the body 10 on the horizontal plane β, avoiding the situation that the liquid drips onto the body 10 and causes the body 10 to be soiled, and the user experience is better. On the other hand, after the nasal cavity cleaning device 100 is used, the side of the body 10 facing away from the nozzle 20 can be placed on the placement plane θ (such as a tabletop or a countertop). At this time, the height direction x of the body 10 is perpendicular to the placement plane θ, and the first plane γ is parallel to the placement plane θ. When the liquid remaining at the water outlet 20b of the nozzle 20 drips along the vertical direction p under the action of gravity, it can avoid the body 10, thereby avoiding the situation that the liquid drips onto the body 10 and causes the body 10 to be soiled, and the user experience is better.

[0056] Wherein, Figure 4The dash-dot line therein represents the first plane γ, and the dashed line represents the projections of the water outlet 20b and the body 10 on the first plane γ.

[0057] Exemplarily, the projection of the water outlet 20b on the first plane γ and the center o of the projection of the body 10 on the first plane γ are spaced along the first direction q. The first plane γ is perpendicular to the height direction x. When the body 10 is in the first posture in the first direction q, at least part of the projection of the water outlet 20b on the horizontal plane β is located outside the projection of the body 10 on the horizontal plane β. In this way, the projection of the water outlet 20b on the first plane γ and the center o of the projection of the body 10 on the first plane γ are spaced along the first direction q, forming a dislocation setting between the water outlet 20b and the center of the body 10. The water outlet 20b is close to the edge of the body 10, which is beneficial for the body 10 to tilt at a certain angle towards the first direction q, so that at least part of the projection of the water outlet 20b on the horizontal plane β is located outside the projection of the body 10 on the horizontal plane β. This is because, when the distance from the water outlet 20b to the body 10 along the height direction x of the body 10 remains unchanged, the smaller the distance between the water outlet 20b and the edge of the body 10, the smaller the angle at which the body 10 needs to tilt.

[0058] Optionally, along the height direction x, the orientation direction of the water outlet 20b is set to face away from the body 10. In this way, when the user uses the nasal cavity cleaning device 100 to clean the nasal cavity, the user can hold the body 10 by hand and make the nozzle 20 fit with the user's nasal cavity. At this time, the orientation direction of the water outlet 20b faces away from the body 10, and the liquid flowing out of the water outlet 20b can directly act on the user's nasal cavity. When the user holds the body 10 by hand, there is no need to flip the body 10 by the wrist to make the water outlet 20b face upward, and the user experience is better.

[0059] In some other embodiments, while the orientation direction of the water outlet 20b faces away from the body 10, it can slightly form an angle with the height direction x and does not need to be parallel to the height direction x. At this time, when the user holds the body 10 by hand, the user can flip the body 10 by a small angle of the wrist, and the liquid flowing out of the water outlet 20b can still directly act on the user's nasal cavity. The wrist flipping angle is small, the user's wrist is in a more comfortable state, and the user experience is better.

[0060] In some embodiments, such as Figures 1 to 3As shown, the nozzle 20 is at least partially configured to be curved and extends away from the body 10 in a bent manner, so that when the body 10 is in the first posture, at least a part of the projection of the water outlet 20b on the horizontal plane β is located outside the projection of the body 10 on the horizontal plane β. In this way, by configuring at least a part of the nozzle 20 to be curved, the shape of the bent extension is used to make the water outlet 20b away from the body 10, and when the body 10 is in the first posture at least in one direction, at least a part of the projection of the water outlet 20b on the horizontal plane β is located outside the projection of the body 10 on the horizontal plane β, and the implementation method is relatively simple and reliable.

[0061] In some other embodiments, the nozzle 20 can also be linear. By connecting the nozzle 20 to the body 10 in an inclined manner, the relative position of the water outlet 20b and the body 10 can be adjusted, and it can also be realized that when the body 10 is in the first posture, at least a part of the projection of the water outlet 20b on the horizontal plane β is located outside the projection of the body 10 on the horizontal plane β. This embodiment does not make specific limitations on this.

[0062] Exemplarily, in combination with Figure 5 As shown, the nozzle 20 includes a pipe portion 21 and a head portion 22. One end of the pipe portion 21 has a water inlet 20a. The pipe portion 21 is connected to the body 10. The pipe portion 21 is configured to be curved and extends away from the body 10. The head portion 22 is provided at the end of the pipe portion 21 away from the body 10. The head portion 22 has a water outlet 20b. The head portion 22 is used to abut against the user's nasal cavity and close the user's nasal cavity. In this way, by configuring the pipe portion 21 to be curved and extending away from the body 10, and connecting the head portion 22 at the end of the pipe portion 21 away from the body 10, the water outlet 20b of the head portion 22 is made away from the body 10, and when the body 10 is in the first posture, at least a part of the projection of the water outlet 20b on the horizontal plane β is located outside the projection of the body 10 on the horizontal plane β, and the implementation method is relatively simple and reliable. Moreover, the head portion 22 can abut against the user's nasal cavity and close the user's nasal cavity, and the liquid flowing out from the water outlet 20b can effectively clean the nasal cavity, avoiding the situation that the liquid flowing out from the water outlet 20b directly flows out between the nasal cavity and the head portion 22 and the liquid fails to effectively clean the nasal cavity.

[0063] Optionally, the head portion 22 and the pipe portion 21 are connected by interference fit. In this way, on the one hand, the connection strength between the head portion 22 and the pipe portion 21 can be improved. On the other hand, by using the interference fit connection method, the connection between the head portion 22 and the pipe portion 21 is tight and the sealing performance is better, and it can prevent the liquid from leaking out from the connection between the head portion 22 and the pipe portion 21.

[0064] Exemplarily, the nozzle 20 further includes a nozzle core 23 disposed within the pipe portion 21 and at one end where the pipe portion 21 is connected to the head 22. The nozzle core 23 is configured to cause the liquid to be ejected in a mist form from the water outlet 20b. In this way, by providing the nozzle core 23 in the pipe portion 21, the liquid can be ejected in a mist form from the water outlet 20b, improving the effect of the liquid in cleaning the user's nasal cavity.

[0065] Optionally, the nozzle core 23 is in interference connection with the pipe portion 21. In this way, on the one hand, the connection strength between the nozzle core 23 and the pipe portion 21 can be improved. On the other hand, by using the interference connection method, the connection between the nozzle core 23 and the pipe portion 21 is tight and the sealing performance is better, which can prevent the liquid from flowing from the connection between the nozzle core 23 and the pipe portion 21 to the nozzle 20 and forming a liquid in a mist form without the action of the nozzle core 23.

[0066] In some embodiments, as Figure 6 shown, the projection of the water outlet 20b on the first plane γ and the center o of the projection of the fuselage 10 on the first plane γ are spaced along the first direction q, and are located outside the projection of the fuselage 10 on the first plane γ. The projection of the water inlet 20a on the first plane γ is located within the projection of the fuselage 10 on the first plane γ and between the projection of the water outlet 20b on the first plane γ and the center o of the projection of the fuselage 10 on the first plane γ. The first plane γ is perpendicular to the height direction x. In this way, on the one hand, by the projection of the water outlet 20b on the first plane γ and the center o of the projection of the fuselage 10 on the first plane γ being spaced along the first direction q, the water outlet 20b and the center of the fuselage 10 are arranged in a staggered manner, and the water outlet 20b is close to the edge of the fuselage 10, which is beneficial to the water outlet 20b having at least a part of its projection on the horizontal plane β located outside the projection of the fuselage 10 on the horizontal plane β when the fuselage 10 is tilted at a certain angle towards the first direction q. This is because, when the distance from the water outlet 20b along the height direction x of the fuselage 10 to the fuselage 10 remains unchanged, the smaller the distance between the water outlet 20b and the edge of the fuselage 10, the smaller the angle at which the fuselage 10 needs to be tilted. On the other hand, by the projection of the water inlet 20a on the first plane γ being located between the projection of the water outlet 20b on the first plane γ and the center o of the projection of the fuselage 10 on the first plane γ, the distance between the water inlet 20a and the water outlet 20b can be shortened, thereby reducing the overall size of the nozzle 20, which is beneficial to the miniaturized design of the nasal cavity cleaning device 100 and convenient for user use.

[0067] Exemplarily, as Figure 7 and Figure 8As shown, the cross-section of the fuselage 10 perpendicular to the height direction x has a length direction y and a width direction z. The dimension of the cross-section along the length direction y is greater than the dimension of the cross-section along the width direction z. The first direction q is parallel to the length direction y. One side of the fuselage 10 along the width direction z is used to be placed on the placement plane θ. In this way, on the one hand, by placing one side of the fuselage 10 along the width direction z on the placement plane θ, a height difference along the width direction z is formed between the nozzle 20 and the placement plane θ, which can avoid the situation that when the fuselage 10 lies flat on the placement plane θ, the nozzle 20 contacts the placement plane θ, resulting in contamination or even damage to the nozzle 20. On the other hand, the dimension of one side surface of the fuselage 10 along the length direction y is larger along the width direction z, and the area of one side of the fuselage 10 along the width direction z is larger. The fuselage 10 can be placed on the placement plane θ more stably. At this time, the width direction z of the fuselage 10 is perpendicular to the placement plane θ, and the dimension of the width direction z of the fuselage 10 is smaller, which can avoid the fuselage 10 from tipping over.

[0068] Among them, Figure 8 The dashed box in

[0069] In some embodiments, as Figure 6 and Figure 9 shown, the nozzle 20 is rotatably connected to the fuselage 10. The nozzle 20 can rotate relative to the fuselage 10 to switch the nozzle 20 to different states. The different states at least include a first state and a second state. The first state is the state where the projection of the nozzle 20 on the first plane γ is within the projection of the fuselage 10 on the first plane γ (as Figure 9 shown), and the second state is the state where at least part of the projection of the water outlet 20b on the first plane γ is outside the projection of the fuselage 10 on the first plane γ (as Figure 6 shown). The first plane γ is perpendicular to the height direction x. In this way, when the user uses the nasal cavity cleaning device 100 to clean the nasal cavity, the nozzle 20 can be rotated so that the nozzle 20 rotates relative to the fuselage 10 to the second state. At this time, the projection of the nozzle 20 on the first plane γ is outside the projection of the fuselage 10 on the first plane γ, and the liquid flowing out of the water outlet 20b of the nozzle 20 can be used for the user to clean the nasal cavity. And when the liquid drips vertically along the vertical direction p under the action of gravity, it can avoid the fuselage 10, thus avoiding the situation that the liquid drips on the fuselage 10 and gets it dirty, and the user experience is better. After the user finishes using, the nozzle 20 can be rotated so that the nozzle 20 rotates relative to the fuselage 10 to the first state. At this time, the projection of the nozzle 20 on the first plane γ is within the projection of the fuselage 10 on the first plane γ, which can reduce the overall occupied space of the nasal cavity cleaning device 100, facilitate storage, and can reduce the risk of damage to the nozzle 20 during storage.

[0070] Among them, Figure 9The dotted line represents the first plane γ, and the dashed line represents the projections of the fuselage 10 and the nozzle 20 on the first plane γ.

[0071] Specifically, the pipe portion 21 is rotatably connected to the fuselage 10, and the pipe portion 21 can rotate relative to the fuselage 10 to switch the nozzle 20 to different states.

[0072] In some embodiments, the nasal cavity cleaning device 100 further includes a holding structure. The holding structure is connected to the pipe portion 21 and the fuselage 10, and the holding structure is used to keep the nozzle 20 in different states. In this way, by connecting the holding structure to the pipe portion 21 and the fuselage 10, the nozzle 20 can be held in a hovering state at different positions, avoiding the situation where the nozzle 20 accidentally rotates relative to the fuselage 10 under external force and changes its state. For example, when the user uses the nasal cavity cleaning device 100 to clean the nasal cavity, the head 22 of the nozzle 20 usually abuts against the nasal cavity. At this time, the holding structure can keep the nozzle 20 in the second state, avoiding the situation where the head 22 drives the pipe portion 21 to rotate relative to the fuselage 10 under the action of the nasal cavity force, changing the state of the nozzle 20 and causing the user to be unable to use the nasal cavity cleaning device 100 normally. Or, when the nozzle 20 is switched to the first state to facilitate the storage of the nasal cavity cleaning device 100, using the holding structure to keep the nozzle 20 in the first state can avoid the situation where the nozzle 20 rotates relative to the fuselage 10 randomly and causes the nozzle 20 to collide and be damaged.

[0073] As an alternative embodiment, the holding structure includes a damping ring (not shown). The damping ring is sleeved on the pipe portion 21, and the circumferential side surface of the damping ring facing away from the pipe portion 21 abuts against the fuselage 10. In this way, by providing a damping force through the damping ring, the damping force can hinder the rotation of the pipe portion 21 relative to the fuselage 10, thereby avoiding the situation where the pipe portion 21 accidentally rotates relative to the fuselage 10.

[0074] As another alternative embodiment, as Figure 5 shown, the holding structure includes a first serrated portion 40 and a second serrated portion (not shown). One serrated portion is disposed around the circumferential side surface of the pipe portion 21, and the second serrated portion is disposed on the fuselage 10 corresponding to the first serrated portion 40, and the second serrated portion is engaged with the first serrated portion 40. In this way, on the one hand, by engaging the first serrated portion 40 with the second serrated portion, the first serrated portion 40 and the second serrated portion can increase the acting force to hinder the rotation of the pipe portion 21 relative to the fuselage 10, thereby avoiding the situation where the pipe portion 21 accidentally rotates relative to the fuselage 10. On the other hand, when the user rotates the nozzle 20 to switch to different states, the first serrated portion 40 and the second serrated portion engage and rotate, which can produce a clear clicking sound to provide operation feedback to the user, and the user experience is better.

[0075] As another alternative embodiment, the holding structure includes a first limiting portion (not shown), a second limiting portion (not shown), and a third limiting portion (not shown). One of the pipe portion 21 and the fuselage 10 is provided with the first limiting portion, and the other of the two is provided with the second limiting portion and the third limiting portion. The second limiting portion is used to connect with the first limiting portion when the nozzle 20 is switched to the first state, and the third limiting portion is used to connect with the first limiting portion when the nozzle 20 is switched to the second state. In this way, when the nozzle 20 is switched to the first state, the second limiting portion is connected to the first limiting portion, which can prevent the nozzle 20 from rotating relative to the fuselage 10, thereby keeping the nozzle 20 in the first state. When the nozzle 20 is switched to the second state, the third limiting portion is connected to the first limiting portion, which can prevent the nozzle 20 from rotating relative to the fuselage 10, thereby keeping the nozzle 20 in the second state.

[0076] An embodiment of the present invention provides a nasal cavity cleaning device 100. By arranging a liquid pumping assembly 30 inside the fuselage 10, the nozzle 20 is connected to the fuselage 10, and the water inlet 20a of the nozzle 20 is communicated with the liquid pumping assembly 30. The liquid pumping assembly 30 can pump the liquid into the nozzle 20 through the water inlet 20a, and the water outlet 20b of the nozzle 20 can discharge the liquid pumped into the nozzle 20, so as to supply the user to clean the nasal cavity. At the same time, when the fuselage 10 is in the first posture in at least one direction, at least part of the projection of the water outlet 20b on the horizontal plane β is located outside the projection of the fuselage 10 on the horizontal plane β. In this way, when the user uses the nasal cavity cleaning device 100 to clean the nasal cavity, by tilting the fuselage 10 by less than 30° in at least one direction, that is, making the height direction x of the fuselage 10 form an angle α with the vertical direction p, when the liquid drips along the vertical direction p under the action of gravity, it can avoid the fuselage 10, thereby preventing the situation that the liquid drips onto the fuselage 10 and makes the fuselage 10 dirty, and the user experience is better.
