[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] The nasal cavity is another important channel for the human body to communicate with the outside world besides the oral cavity. It is used much more frequently than the oral cavity because people need to breathe every moment. However, since the environment around us is not pure, some impurities and harmful substances are blocked in the nasal cavity by the filtering function of the nasal cavity when they are inhaled into the human body, preventing them from entering the lungs. However, if these impurities and harmful substances are not cleaned in time and remain in the nasal cavity for a long time, they may produce more bacteria and cause nasal diseases.

[0042] There are currently two types of electric nasal cleaners on the market. One is an electric nasal washer, which can be used to treat rhinitis and other problems, and can also care for healthy nasal cavities. It mainly relies on the impact of saline water flow to expel pathogenic bacteria and dirt that have accumulated in the nasal cavity, restore the nasal cavity to a normal physiological environment, restore the nasal cavity's self-detoxification function, and achieve the purpose of protecting the nasal cavity. It can also treat the nasal cavity with liquid medicine; the other is an electric nasal aspirator, which is mainly used to suck out the snot for infants, babies and the elderly. Due to various reasons such as intelligence and physical condition, these people cannot or are not convenient to blow their noses by themselves. If the snot is not sucked out in time, it will block the nasal passage and cause breathing problems, so a nasal aspirator is needed to suck out the snot.

[0043] In the above-mentioned nasal rinser, there is an assembly gap between the cup cover and the pipette of the rinsing head part. Therefore, during the use of the nasal rinser, the waste liquid flowing to the upper surface of the cup cover will flow into the medicine liquid cavity along the assembly gap between the cup cover and the pipette, contaminating the medicine in the medicine liquid cavity.

[0044] See also Figures 1 to 3 , Fig.10 The nasal irrigation head 10 proposed by the utility model is used for the nasal cleaning device 1. The nasal irrigation head 10 is detachably connected to the main unit of the nasal cleaning device 1. The nasal irrigation head 10 includes a cup body 100 and a cup cover 200. The upper end of the cup body 100 is formed with an opening 110, and the bottom is formed with an air outlet pipe 120 extending to the opening 110. The bottom of the air outlet pipe 120 is formed with an air inlet 121, and the top of the air outlet pipe 120 is formed with an air jet hole 122. The air inlet 121 is connected to the cup cover 200. The bottom of the cup body 100 is connected to the side facing away from the opening 110, and the jet hole 122 is connected to the air inlet 121 through the air outlet channel 123 in the air outlet pipe 120; the cup cover 200 covers the cup body 100 to form the accommodating cavity 101, and the cup cover 200 includes a cover body 210 and a liquid suction tube 220, the liquid suction tube 220 is arranged through the cover body 210, the liquid suction tube 220 is sleeved with the air outlet pipe 120, and a liquid outlet gap 300 is formed between the liquid suction tube 220 and the air outlet pipe 120 (see Figure 4 ), the upper end of the liquid suction tube 220 is provided with a liquid injection hole 221 connected to the injection hole 122, and the liquid suction tube 220 and the cover body 210 are integrally formed.

[0045] Specifically, after the nasal irrigation head 10 and the host 30 of the nasal cleaner 1 are connected together, they play the role of the aforementioned electric nasal irrigator. The nasal irrigation head 10 and the host 30 are detachably connected, which is convenient for disassembly, assembly and replacement of the nasal irrigation head 10. The nasal irrigation head 10 includes a cup body 100, which is mainly used to store clean cleaning liquid and waste liquid after use. The cup body 100 is arranged in a hollow cylindrical shape, and an opening 110 is formed at its upper end, and an air outlet pipe 120 extends from the bottom of the cup body 100 to the opening 110, and an air outlet channel 123 is formed in the air outlet pipe 120, and one end of the air outlet channel 123 forms an air jet hole 122, and the other end forms an air inlet 121. The cross-section of the cup body 100 can be circular, elliptical, rectangular or other special shapes, and there is no specific limitation on this. The host 30 of the nasal cleaner 1 is provided with an air pump, a circuit board, a battery, a motor, a touch component, etc., wherein the air pump has an air inlet end and an air outlet end, and the air inlet 121 is connected to the side of the bottom of the cup body 100 facing away from the opening 110. When the nasal irrigation head 10 and the host 30 are assembled, the air inlet 121 is connected to the air outlet end of the air pump so that the gas blown out by the air pump can be directly blown into the air outlet channel 123 to generate a high-speed airflow.

[0046] See also Figures 3 to 5The cup cover 200 covers the cup body 100 to form a accommodating chamber 101, wherein a liquid pipette 220 is arranged to penetrate the cover body 210, and the liquid pipette 220 is sleeved with the air outlet pipe 120, and a liquid outlet gap 300 is formed between the liquid pipette 220 and the liquid outlet pipe, and the liquid outlet gap 300 is communicated with a chamber for placing the cleaning liquid. It can be understood that the inner diameter of the liquid pipette 220 is larger than the outer diameter of each corresponding part of the liquid outlet pipe. When the air jet hole 122 is in the air jet state, a negative pressure area is formed between the liquid pipette 220 and the liquid outlet pipe, and the cleaning liquid in the accommodating chamber 101 will overcome gravity and be sprayed out from the air jet hole 221 of the liquid pipette 220, so that the user can clean the nasal cavity.

[0047] When the cleaning liquid has finished flushing the user's nasal cavity, the used cleaning liquid (i.e., waste liquid) will flow to the upper surface of the cover body 210 of the cup cover 200. The existing pipette 220 and the cover body 210 are usually separately arranged. Therefore, the waste liquid generated by the user after use will flow into the medicine liquid cavity through the assembly gap between the cup cover 200 and the pipette 220, contaminating the medicine in the medicine liquid cavity. Therefore, the pipette 220 and the cover body 210 of the present application are integrally formed. On the one hand, the pipette 220 and the cover body 210 are integrally formed, and no assembly is required between the two, and there is no assembly gap. Therefore, the waste liquid generated by the user after use is not easy to flow into the medicine liquid cavity along the assembly gap between the cup cover 200 and the pipette 220, contaminating the medicine in the medicine liquid cavity. On the other hand, the integrally formed pipette 220 and the cover body 210 reduce a production process and reduce the trouble of assembly between the two, further improving the production and assembly efficiency.

[0048] The technical solution of the present utility model is to integrally form the pipette 220 and the cover body 210. On the one hand, there is no need to assemble the two and there is no assembly gap. Therefore, the waste liquid generated by the user after use is not easy to flow into the medicine liquid cavity along the assembly gap between the cup cover 200 and the pipette 220 to contaminate the medicine in the medicine liquid cavity. On the other hand, the integrally formed pipette 220 and the cover body 210 reduce a production process and the trouble of assembling the two, thereby further improving the production and assembly efficiency.

[0049] See also Figures 3 to 6 In one embodiment, a partition plate 130 is provided in the accommodating chamber 101, and the partition plate 130 divides the accommodating chamber into a liquid storage chamber 101a and a waste liquid chamber 101b; the air outlet pipe 120 is provided in the liquid storage chamber 101a, and the cover body 210 is provided with a first liquid leakage port 211 connected to the waste liquid chamber 101b.

[0050] Specifically, a partition plate 130 is provided in the accommodating chamber 101, and the partition plate 130 divides the accommodating chamber into a liquid storage chamber 101a and a waste liquid chamber 101b. The liquid storage chamber 101a and the waste liquid chamber 101b are arranged left and right in the horizontal direction. The liquid storage chamber 101a is used to store clean cleaning liquid, and the waste liquid chamber 101b is used to store waste liquid generated after flushing the user's nasal cavity (that is, the cleaning liquid after use). The air outlet pipe 120 is arranged in the liquid storage chamber 101a, so that the liquid outlet gap 300 formed between the liquid suction tube 220 and the air outlet pipe 120 is connected to the liquid storage chamber 101a, and the cleaning liquid in the liquid storage chamber 101a is sucked into the liquid outlet gap 300 and sprayed out from the liquid spray port. The cover body 210 is provided with a first liquid leakage port 211, which is connected to the waste liquid cavity 101b, so that the waste liquid generated when the user uses the nasal irrigation head 10 flows to the upper surface of the cover body 210 and then flows into the waste liquid cavity 101b through the first liquid leakage port 211. The setting of the waste liquid cavity 101b is convenient for collecting waste liquid after use by the user.

[0051] See also Figure 5 Furthermore, a guide surface 212 is formed on the upper surface of the cover body 210, and the guide surface 212 extends downwardly from the edge of the cover body 210 to the first liquid leakage port 211. In this way, the waste liquid flowing onto the guide surface 212 will flow to the first liquid leakage port 211 under the action of gravity and finally flow into the waste liquid chamber 101b, which is convenient for collecting the waste liquid.

[0052] See also Figure 5 and Figure 6 In one embodiment, the cover 210 is provided with a sealing groove 213 that matches the shape of the partition plate 130, and the top of the partition plate 130 is adapted to be connected with the sealing groove 213. Specifically, in order to further separate the liquid storage chamber 101a and the waste liquid chamber 101b, a sealing groove 213 that matches the shape of the partition plate 130 is provided on the cover 210, and at the same time, the top of the partition plate 130 is sealed and connected with the sealing groove 213, and a sealing structure can be provided in the sealing groove 213 to achieve a sealed connection effect, so as to ensure that when the cup body 100 is inverted, the waste liquid in the waste liquid chamber 101b and the cleaning liquid in the liquid storage chamber 101a will not flow through each other, so as to avoid the waste liquid from contaminating the cleaning liquid.

[0053] See also Figure 6, further, the partition plate 130 includes two straight plate sections 131, and an arc plate section 132 located between the two straight plate sections 131, the two sides of the arc plate section 132 are respectively connected to the two sides of the two straight plate sections 131, the arc plate section 132 is used to avoid the outlet pipe 120, and the center of the arc plate section 132 and the center of the outlet pipe 120 are staggered. Specifically, the cross section of the outlet pipe 120 is circular, and since the partition plate 130 is arranged in the accommodating chamber 101, in order to ensure that the volume difference between the liquid storage chamber 101a and the waste liquid chamber 101b is not too large, the partition plate 130 is arranged as a whole close to the middle of the accommodating chamber 101. Since the outlet pipe 120 is also arranged in the middle of the accommodating chamber 101, the arc plate section 132 is arranged on the partition plate 130 corresponding to the outlet pipe 120 to avoid it. The arc of the arc plate segment 132 may be an arc of a full circle or an arc of an ellipse, and there is no specific limitation on this.

[0054] It should be emphasized that the center of the arc plate segment 132 is offset from the center of the air outlet pipe 120. The air outlet pipe 120 is arranged at the center of the accommodating cavity 101, that is, the center line of the air outlet pipe 120 and the center line of the cup body 100 are coaxially arranged, which facilitates the connection between the air outlet pipe 120 and the air outlet end of the air pump. Considering that the cleaning liquid will be lost during the actual use of the product by the user, that is, the cleaning liquid after use will not all flow back into the waste liquid chamber 101b, and in order to ensure that there is enough cleaning liquid in the cup body 100, the volume of the liquid storage chamber 101a is set to be larger than the volume of the waste liquid chamber 101b. In this embodiment, the partition plate 130 is arranged as a whole close to the middle of the accommodating chamber 101 and biased to one side of the waste liquid chamber 101b, so that the volume of the liquid storage chamber 101a is larger than the volume of the waste liquid chamber 101b. Therefore, the center of the circular arc plate segment 132 used to avoid the outlet pipe 120 and the center of the outlet pipe 120 are staggered. Further, the center of the circular arc plate segment 132 is located on the side of the center of the outlet pipe 120 away from the partition plate 130, so as to avoid the space enclosed by the arc half segment occupying too much space of the waste liquid chamber 101b.

[0055] See also Figure 6On the basis of the previous embodiment, the cover body 210 is further provided with an anti-fool segment 214, which is connected to the outer wall of the sealing slot 213. Specifically, since the partition plate 130 is arranged close to the middle of the accommodating chamber 101 as a whole, and is biased towards one side of the waste liquid chamber 101b, that is, the connection line formed between the two sides of the partition plate 130 and the cavity wall of the accommodating chamber 101 is not a connection line passing through the axis of the accommodating chamber 101, when the cover body 210 and the cup cover 200 are assembled, the cover body 210 has the disadvantage of being installed upside down with the cup cover 200 (that is, the sealing slot 213 and the top of the partition plate 130 are not sealed), therefore, the cover body 210 is provided with an anti-fool segment 214, which is connected to the outer wall of the sealing slot 213, to avoid being installed upside down when the cup cover 200 and the cup body 100 are assembled.

[0056] See also Figure 3 and Figure 5 In one embodiment, the bottom of the accommodating cavity 101 extends downwardly from one side of the liquid storage cavity 101a to one side of the waste liquid cavity 101b. Specifically, the nasal irrigation head 10 has a front side and an opposite rear side. The front side can be understood as the side facing the user when the nasal irrigation head 10 is in use, and the rear side can be understood as the side facing away from the user when the nasal irrigation head 10 is in use. Considering that when the user uses it, the nasal cleaner 1 is generally tilted and held at a certain angle to the horizontal direction. During operation, the cleaning liquid in the liquid storage cavity 101a will rush into the human nasal cavity to clean the nasal cavity and flow out of the nasal cavity. The waste liquid flowing out of the nasal cavity will flow into the waste liquid cavity 101b. Therefore, the waste liquid cavity 101b is located on the side close to the user when in use, that is, it is arranged close to the front side of the nasal cleaner 1.

[0057] Since the waste liquid chamber 101b is arranged close to the front side and the liquid storage chamber 101a is arranged close to the rear side, the bottom of the accommodating chamber 101 extends downwardly from one side of the liquid storage chamber 101a to one side of the waste liquid chamber 101b, that is, the bottom of the accommodating chamber 101 extends downwardly from the rear side to the front side of the nasal irrigation head 10. Such an arrangement can ensure that when the nasal irrigation head 10 is in use, the cleaning liquid in the liquid storage chamber 101a can flow along the inclined bottom to the air outlet pipe 120, which is conducive to the exhaustion of the cleaning liquid and avoids a large amount of unusable cleaning liquid remaining in the liquid storage chamber 101a.

[0058] See also Figures 7 to 9 In another embodiment of the utility model, the accommodating chamber 101 is a liquid storage chamber 101a, the cup cover 200 is formed with a waste liquid chamber 101b and the cup cover 200 at least partially extends into the liquid storage chamber 101a, the liquid storage chamber 101a and the waste liquid chamber 101b are isolated, and the air outlet pipe 120 is arranged in the liquid storage chamber 101a.

[0059] Specifically, the accommodating chamber 101 is a liquid storage chamber 101a for storing clean cleaning liquid. The cup cover 200 covers the cup body 100 and the cup cover 200 forms a waste liquid chamber 101b isolated from the liquid storage chamber 101a. The waste liquid chamber 101b is used to store waste liquid generated after flushing the user's nasal cavity (i.e., the cleaning liquid after use). The cup cover 200 at least partially extends into the liquid storage chamber 101a. That is, the cup cover 200 itself forms a waste liquid chamber 101b, and the portion of the cup cover 200 extending into the liquid storage chamber 101a occupies part of the The space of the liquid storage chamber 101a, the waste liquid chamber 101b and the liquid storage chamber 101a are arranged in the vertical direction. On the one hand, the waste liquid chamber 101b and the liquid storage chamber 101a arranged in the vertical direction have a compact structure, which reduces the overall height of the nasal irrigation head 10; on the other hand, the portion of the cup cover 200 extending into the liquid storage chamber 101a occupies part of the space of the liquid storage chamber 101a, and the space in the cup body 100 is reasonably utilized to ensure that the volume of the liquid storage chamber 101a and the volume of the waste liquid chamber 101b are not too different, and avoid the liquid storage chamber 101a being too large or the waste liquid chamber 101b being too small.
