Description

Technical Field

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

[0002] In daily life, people need to breathe all the time. However, with the increasingly serious environmental pollution, the air people inhale is not pure. These impurities and harmful substances are blocked in the nasal cavity by the filtering function of the nasal cavity when inhaled into the human body, so that they cannot enter the lungs. However, if these impurities and harmful substances are not cleaned in time and stay in the nasal cavity for a long time, more bacteria may be produced, leading to nasal cavity diseases. Therefore, the nasal washer came into being. The nasal washer uses a certain pressure to send the cleaning liquid into the nasal cavity, so as to discharge the dirt that has accumulated in the nasal cavity, restore the normal physiological environment of the nasal cavity, and achieve the purpose of protecting the nasal cavity. The defect of the existing nasal washer is that it cannot collect the waste liquid well after cleaning the nasal cavity. Summary of the Utility Model

[0003] Based on this, the purpose of the present utility model is to provide a nasal washer head assembly and a nasal washer that can collect the waste liquid well after cleaning the nasal cavity.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A nasal washer head assembly includes a barrel body, a liquid inlet pipe, an upper cover, and a soft nasal washer head; a circular partition is arranged inside the barrel body, and the circular partition divides the interior of the barrel body into a clean liquid cavity and a waste liquid cavity, and the waste liquid cavity is located outside the clean liquid cavity; an air inlet pipe is arranged in the middle of the clean liquid cavity of the barrel body; the liquid inlet pipe is sleeved on the air inlet pipe, and there is a liquid inlet gap between the liquid inlet pipe and the air inlet pipe; the upper cover is installed on the top of the barrel body; the upper cover includes a clean liquid cavity cover body, a circular baffle, and a plurality of connecting columns. The clean liquid cavity cover body covers the clean liquid cavity and is clamped with the outer side surface of the top of the circular partition; a through hole is arranged at the top of the clean liquid cavity cover body, and the top of the liquid inlet pipe passes through the through hole; the circular baffle is arranged at intervals on the outer periphery of the clean liquid cavity cover body and is located above the outer side wall of the barrel body; the plurality of connecting columns are respectively arranged between the clean liquid cavity cover body and the circular baffle, and a waste liquid recovery hole is formed at intervals between every two adjacent connecting columns, and the waste liquid recovery hole is communicated with the waste liquid cavity; the soft nasal washer head is installed on the through hole of the clean liquid cavity cover body, and the soft nasal washer head is a hollow structure and surrounds the top of the liquid inlet pipe.

[0006] For the nasal cleaning head assembly of the present utility model, the purified nasal cleaning liquid is added to the purified liquid chamber. The liquid inlet pipe is sleeved on the air inlet pipe, and the upper cover and the soft nasal cleaning head are installed. The soft nasal cleaning head is inserted into the nostril, and the air inlet pipe is made to pass air. The purified nasal cleaning liquid is sucked in from the liquid inlet gap under negative pressure, atomized and ejected from the top of the liquid inlet pipe, enters the nostril through the soft nasal cleaning head, and cleans the nasal cavity. After the cleaning, the waste nasal cleaning liquid is diverted outside the soft nasal cleaning head and the cover of the purified liquid chamber, and enters the waste liquid chamber through the waste liquid recovery hole. The nasal cleaning head assembly of the present utility model can well collect the waste liquid after cleaning the nasal cavity and prevent the waste liquid from entering the purified liquid chamber to contaminate the purified liquid.

[0007] Further, the bottom of the air inlet pipe penetrates through the bottom of the barrel body, and air holes are provided at the top of the air inlet pipe; atomization holes are provided at the top of the liquid inlet pipe, and the atomization holes are communicated with the air holes. The air flowing through the air inlet pipe flows out from the air holes and then flows out from the atomization holes. Among them, after the air flows out of the air holes, a negative pressure is formed in the liquid inlet gap, sucking the purified nasal cleaning liquid in the purified liquid chamber to flow towards the atomization holes. The purified nasal cleaning liquid achieves an atomization effect under the action of the air flow and is atomized and ejected from the atomization holes.

[0008] Further, a plurality of first protrusions are provided at intervals on the outer periphery of the air inlet pipe, so as to form a liquid inlet gap between the outer side wall of the air inlet pipe and the inner side wall of the liquid inlet pipe. This prevents the outer side wall of the air inlet pipe from being in contact with the inner side wall of the liquid inlet pipe.

[0009] Further, a stepped structure is provided on the outer side wall at the top of the air inlet pipe, and a plurality of positioning portions are provided at intervals on the inner periphery of the inner side wall at the top of the liquid inlet pipe, and each positioning portion is matched with the stepped structure. Through this design, the error of sleeving the liquid inlet pipe on the air inlet pipe can be reduced, and the gap between the outer end face at the top of the air inlet pipe and the inner end face at the top of the liquid inlet pipe can be controlled well, which is beneficial to the dispersion of the purified nasal cleaning liquid and prevents poor atomization caused by contact. At the same time, since there are intervals between the positioning portions, it does not affect the flow of the purified nasal cleaning liquid, enabling the purified nasal cleaning liquid to smoothly enter the liquid inlet gap and be atomized and ejected under the action of the air flow at the atomization holes.

[0010] Further, an umbrella-shaped structure is provided at the bottom of the liquid inlet pipe, and the umbrella-shaped structure extends outward from the bottom of the liquid inlet pipe; a plurality of second protrusions are provided at intervals on the outer periphery of the bottom surface of the umbrella-shaped structure, so as to form a gap between the bottom surface of the umbrella-shaped structure and the upper bottom surface of the barrel body; a liquid inlet groove is formed between every two second protrusions. By setting the bottom of the liquid inlet pipe as an umbrella-shaped structure and providing a plurality of second protrusions on the outer periphery of its bottom surface, the bottom of the liquid inlet pipe has a larger liquid inlet space, which is beneficial to accelerating the liquid inlet and sucking the purified liquid in the purified liquid chamber clean.

[0011] Furthermore, the cover of the purified liquid chamber is provided with a diversion portion; the diversion portion extends obliquely downward from the through hole; the cover of the purified liquid chamber is further provided with a clamping portion, the clamping portion is connected to the outer periphery of the diversion portion and extends downward; the inner side surface of the clamping portion of the cover of the purified liquid chamber is clamped with the outer side surface of the top of the annular partition. The diversion of the waste liquid is accelerated through the diversion portion, so that the waste liquid falls into the waste liquid chamber through the waste liquid recovery hole; at the same time, through the clamping action of the clamping portion, the waste liquid chamber can also be isolated from the purified liquid chamber, preventing the waste liquid from entering the purified liquid chamber during the process of being recovered into the waste liquid chamber.

[0012] Furthermore, the outer periphery of the diversion portion is provided with an arc edge with a downward concave. By designing a downward concave arc edge on the outer periphery of the diversion portion, the diversion of the waste liquid can be further enhanced, accelerating the fall of the waste liquid at the outer peripheral position of the diversion portion, and enabling the waste liquid to quickly fall into the waste liquid chamber.

[0013] Furthermore, the inner side of the cover of the purified liquid chamber is provided with an abutting portion; the inner side surface of the clamping portion of the cover of the purified liquid chamber is clamped with the outer side surface of the top of the annular partition, and the abutting portion abuts against the top end of the annular partition. An abutting portion is designed on the inner side of the cover of the purified liquid chamber to facilitate the more stable installation of the cover of the purified liquid chamber on the top of the annular partition.

[0014] As a preferred solution, the plurality of connecting columns are respectively installed horizontally between the cover of the purified liquid chamber and the annular baffle. The plurality of connecting columns are spaced apart, and the plurality of connecting columns are horizontally arranged, and both ends of the plurality of connecting columns are respectively connected to the outer side of the cover of the purified liquid chamber and the inner side of the annular baffle.

[0015] As another preferred solution, the plurality of connecting columns are respectively installed obliquely between the cover of the purified liquid chamber and the annular baffle, and are inclined downward from the end close to the annular baffle to the end close to the cover of the purified liquid chamber. When the waste liquid falls on the connecting columns, the inclined arrangement of the connecting columns can be utilized to accelerate the diversion of the waste liquid on the connecting columns, so that the waste liquid falls from the outer side of the cover of the purified liquid chamber into the waste liquid chamber through the waste liquid recovery hole.

[0016] The present utility model further provides a nasal washer, including the nasal tip assembly described in any one of the above.

[0017] Furthermore, the nasal washer further includes a main body, the main body includes a main body housing, and an air pump arranged in the main body housing; the bottom of the barrel body of the nasal tip assembly is detachably installed on the top of the main body housing; and the air inlet pipe is communicated with the air pump.

[0018] The nasal washer adopting the nasal tip washing component of the present utility model can well collect the waste liquid after washing the nasal cavity, and avoid the waste liquid from entering the clean liquid cavity to contaminate the clean liquid.

[0044] For the nasal washing nozzle assembly of this embodiment, nasal washing liquid purified liquid is placed in the liquid purification chamber 12, and the liquid inlet pipe 2, the upper cover 3 and the soft nasal washing nozzle 4 are assembled. After the air inlet pipe 14 passes through gas, the nasal washing liquid purified liquid enters from the liquid inlet gap between the liquid inlet pipe 2 and the air inlet pipe 14, is atomized and sprayed out at the top of the liquid inlet pipe 2, enters the nasal cavity through the hollow structure of the soft nasal washing nozzle 4, and washes the inside of the nasal cavity. The waste nasal washing liquid after washing then enters the waste liquid chamber 13 through the soft nasal washing nozzle 4 and the diversion outside the liquid purification chamber cover body 31 through the waste liquid recovery hole 34 to collect the waste liquid after washing the nasal cavity.

The plurality of first protrusions 142 are evenly and spacedly arranged on the outer periphery of the air inlet pipe 14 and are close to the upper bottom surface of the barrel body 1. When the liquid inlet pipe 2 is sleeved on the air inlet pipe 14, due to the action of the first protrusions 142, a liquid inlet gap is formed between the outer side wall of the air inlet pipe 14 and the inner side wall of the liquid inlet pipe 2, preventing the outer side wall of the air inlet pipe 14 and the inner side wall of the liquid inlet pipe 2 from being in contact with each other. At the same time, since the plurality of first protrusions 142 are spaced apart, the purified nasal washing liquid can smoothly enter the liquid inlet gap and be atomized and ejected under the action of the air flow at the atomization holes 21. In this embodiment, the number of the first protrusions 142 is set to 4.

[0047] In this embodiment, in order to further enhance the atomization effect of the purified nasal washing liquid at the top position of the liquid inlet pipe 2, please refer to Figure 4 and Figure 7 , a stepped structure 143 is provided on the outer side wall at the top of the air inlet pipe 14, that is, in this embodiment, a structural design is carried out at the top position of the air inlet pipe 14 where the "outer diameter of the upper part" is smaller than the "outer diameter of the lower part", so as to form the stepped structure 143 at its joint surface; a plurality of positioning parts 23 are designed at the corresponding positions on the inner side wall at the top of the liquid inlet pipe 2. The plurality of positioning parts 23 are spaced and evenly arranged on the inner periphery of the inner side wall at the top of the liquid inlet pipe 2.
