Description

Technical Field

[0001] The utility model relates to the technical field of nasal washers, in particular to a nozzle for a nasal washer. Background Art

[0002] A nasal washer is a tool for flushing the nasal cavity. It usually uses a certain pressure or suction, or gravity, or mechanical pressure to send physiological saline into the nostrils, flowing through the part of the nasal vestibule exposed outside the head, the nasal sinuses, the nasal passages around the nasopharynx, and discharging from one nostril or from the mouth. Through the above paths, with the help of the bactericidal effect of physiological saline itself and the impact force of the water flow, the pathogenic substances and dirt accumulated in the nasal cavity are discharged, so as to restore the normal physiological environment of the nasal cavity, restore the self-detoxification function of the nasal cavity, and achieve the purpose of protecting the nasal cavity.

[0003] Publication (Announcement) No.: CN209500234U discloses a nasal washer with a nozzle that can be quickly replaced, including a bottle body, a bottle cap that can be tightened and loosened on the upper part of the bottle body, a diversion tube integrally formed and connected to the upper part of the bottle cap, a nozzle detachably installed at the end of the diversion tube, a clamping part provided on the diversion tube corresponding to the nozzle, the nozzle including a connecting part clamped to the clamping part, a nozzle provided on the connecting part, a clamping bar provided on the clamping part, a clamping groove provided on the connecting part, and a sealing ring provided on the connecting part corresponding to the clamping part; a base is fixedly connected to the bottom of the bottle body, a pressure pump is installed inside the base, a control circuit board electrically connected to the pressure pump, and a power supply provided on one side of the control circuit board and electrically connected to the control circuit board. The nozzle of this nasal washer with a nozzle that can be quickly replaced is detachably installed with the diversion tube by a clamping method. Although this installation method can achieve the disassembly of the nozzle, it has defects. The clamping needs to be achieved by an interference fit to ensure the stable connection between the nozzle and the diversion tube. The interference fit will cause difficulties in both installation and disassembly. In both processes, the user needs to apply a certain force, but this method has obvious limitations and misleading, that is, whether the user has the force to satisfy the connection between the two when installing the nozzle, or whether the interference fit is really installed in place. Conversely, whether the user has the force to satisfy the connection between the two when disassembling the nozzle. Content of the Utility Model

[0018] The present utility model will be further described below with reference to the accompanying drawings:

[0019] Referring to the accompanying drawings: This nasal irrigation nozzle for a nasal irrigator includes a nozzle tube 1 and a nozzle 2 detachably connected to the water outlet end of the nozzle tube 1. A partition 3 is provided at a position above the middle of the nozzle tube 1 inside the nozzle tube 1. The partition 3 divides the water flow channel inside the nozzle tube 1 into a water flow section 11 communicating with the nasal irrigator bottle body and an installation section 12 for installing the nozzle 2. An extension rod 31 extending into the installation section 12 is provided on the partition 3. A diversion channel 31-a is provided inside the extension rod 31, which penetrates through the extension rod 31 and the partition 3 and communicates with the water flow section 11. The upper part of the extension rod 31 is placed inside the water flow channel of the nozzle 2, and a sealing plug 4 hermetically connected to the water flow channel of the nozzle 2 is provided on the part of the extension rod 31 placed inside. The principle of the present utility model is that the partition 3 is used to divide the water flow channel of the nozzle tube 1, so that two spaces can be obtained, namely the water flow section 11 and the installation section 12. And an extension rod 31 for water outlet is provided on the partition 3. The extension rod 31 is combined with the nozzle 2 by the sealing plug 4. The sealing plug 4 is made of rubber material. In this way, it can not only increase the connection stability between the sealing plug 4 and the nozzle 2, but also achieve good sealing performance to avoid leakage during water spraying. Compared with the prior art, the connection difficulty is reduced, and it is more convenient to replace the nozzle 2.

[0020] The installation section 12 is provided with locking nodes 5 distributed on both sides on the nozzle tube 1. The nozzle 2 is provided with locking plugs 6 that match the number and position of the locking nodes 5 and prevent the nozzle 2 from detaching from the nozzle tube 1 when combined with the locking nodes 5. Such a setting enables the nozzle 2 and the nozzle tube 1 to always maintain a connected state, that is, it strengthens the connection strength between the sealing plug 4 made of rubber material and the nozzle 2, thereby effectively preventing the nozzle 2 from detaching from the nozzle tube 1.

[0021] The locking node 5 is provided with a first guiding channel 7 and a second guiding channel 8 on the nozzle 1 to guide the locking plug 6 to reach the locking node 5 along the assembly direction. The nozzle 2 rotates by the movement of the locking plug 6 in the corresponding second guiding channel 8. Through the first guiding channel 7, the second guiding channel 8, and the locking node 5, an operation mode of tool - free and part - free assembly of the locking plug 6 can be realized, which is suitable for rapid assembly and convenient assembly. Moreover, the assembly direction provided by the first guiding channel 7 is consistent with the assembly direction of the nozzle 2 and the sealing plug 4. At the same time, the first guiding channel 7 and the second guiding channel 8 also extend the total length of the route for the locking plug 6 to reach the locking node 5, which can also increase the difficulty of the locking plug 6 escaping; the rotation is considered because the water flow channels of the sealing plug 4 and the nozzle 2 are coaxial, that is, after the nozzle 2 and the sealing plug 4 are combined, the movement form of the nozzle 2 is limited, and the only movement form that can be shown is rotation. Moreover, the first guiding channel 7 (vertical) and the second guiding channel 8 (horizontal) are in an L - shaped configuration, so the nozzle 2 can enter the second guiding channel 8 after rotation.

[0022] The two second guiding channels 8 extend in different directions on both sides to match the rotational movement of the nozzle 2. Such a setting is considered because after the nozzle 2 rotates, the two locking plugs 6 will change accordingly, that is, one locking plug 6 moves to the left and one locking plug 6 moves to the right. Therefore, the two second guiding channels 8 extending in different directions on both sides can meet the changes of the two locking plugs 6 following the rotation of the nozzle 2.

[0023] The nozzle 1 is provided with a turning channel 9 that guides the locking plug 6 to reach the second guiding channel 8 from the first guiding channel 7 by turning in the assembly direction. The turning channel 9 connects the first guiding channel 7 and the second guiding channel 8. The first guiding channel 7 and the second guiding channel 8 are basically in a straight - line extension direction, while the turning channel 9 is basically in an arc - line extension direction. Thus, when the locking plug 6 slides in the turning channel 9, the corresponding turning assembly direction is an arc - shaped direction, which can be clearly felt by the user and will play a corresponding prompting role, enabling the user to anticipate that they are about to reach the turning channel 9, which also means that the locking plug 6 is about to enter the turning channel 9, and can avoid the user's misjudgment.

[0024] The turning channel 9 is formed with a fitting wall 91 that completely fits on a part of the surface of the locking plug 6 when the locking plug 6 reaches the turning channel 9, so that the locking plug 6 is accurately positioned in the turning channel 9 to match the accuracy of the locking plug 6 entering the second guiding channel 8.

[0025] The locking node 5 includes a semi-enclosing wall 51 communicating with the second guiding channel 8, and a locking space 52 defined within the semi-enclosing wall 51 and allowing the locking plug 6 to be placed therein. The semi-enclosing wall 51 abuts against the locking plug 6 in the direction opposite to the assembly direction. When the locking plug 6 is placed within the locking space 52, the locking plug 6 abuts against the semi-enclosing wall 51, thereby preventing the locking plug 6 from returning along the original path, thus completing the locking state of the locking plug 6 and maintaining the connection state of the nozzle 2 to the nozzle tube 1.

[0026] A holding piece 61 located outside the locking node 5 is provided on one end face of the locking plug 6 where it is placed in the locking node 5. That is, when the user performs a locking or unlocking action on the nozzle 2, the user can apply a force with fingers (thumb and index finger) to the holding piece 61. Since the usable area of the holding piece 61 is larger than the usable area of the locking plug 6, sufficient contact area can be provided, thereby facilitating the user to apply a force to drive the nozzle 2 to rotate.

[0027] Although the present utility model has been illustrated and described with reference to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details may be made within the scope of the claims.
