Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, specifically to an intelligent oral moisturizing sprayer. Background Technology

[0002] Oral humidifying sprays are devices used to relieve dry mouth and are widely used by patients with xerostomia, postoperative care, and people who wear braces or dentures for extended periods. Current oral humidifying sprays primarily use manual pressing or electric pumps to atomize the liquid in the spray bottle and spray it out, thereby moisturizing the user's oral mucosa and improving the discomfort of dry mouth.

[0003] However, during use, a small amount of incompletely atomized liquid may remain near the spray nozzle. This residual liquid can accumulate around the nozzle, potentially causing blockage, reducing the spray effect, and even becoming a breeding ground for bacteria, thus affecting the user's oral hygiene. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent oral moisturizing sprayer.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A bottle cap for sealing the spray nozzle is rotatably provided on one side of the base. A hollow pressure block is fixed inside the bottle cap at the position where it mates with the spray nozzle by a cover block.

[0008] A flow guide groove is provided on the side wall of the spray head near the side with a lower horizontal height of the spray nozzle. The bottom end of the flow guide groove passes through the bottom end of the spray head and extends out of the base. When the pressure block closes the spray nozzle with the rotation of the bottle cap, the pressure block fits against the spray nozzle from the top of the spray nozzle and slides from the top of the spray nozzle to the bottom of the spray nozzle. The pressure block squeezes the liquid remaining at the spray nozzle into the flow guide groove.

[0009] Preferably, the top of the spray head is inclined away from the connection point between the bottle cap and the spray head, and the angle between the top of the spray head and the base is in the range of 30 degrees to 45 degrees.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Example

[0027] like Figures 1-3 As shown, an intelligent oral moisturizing sprayer includes a spray bottle 1, a spray head 2 is threadedly connected to the top of the spray bottle 1 via a base 201, the base 201 of the spray head 2 is threadedly connected to the spray bottle 1, and the spray head 2 draws liquid from the cavity of the spray bottle 1 via a water pump.

[0028] A spray head 2 is connected to one end of a spray bottle 1 and has a straw fixed to it. The straw is equipped with a water pump that actively draws in liquid. A control button 31 for controlling the water pump is located on one side of the spray bottle 1 via a fixed control box 3. The control box 3 integrates an intelligent control module with a preset quantitative control program. When the control button 31 is pressed, the water pump automatically draws in the corresponding volume of liquid according to the set spray volume and automatically stops working after completing one quantitative spray. Furthermore, the control box 3 can be further equipped with a mode adjustment function, allowing users to select different spray volume modes according to their needs, such as single small-dose, medium-dose, or large-dose sprays, to meet the usage needs of different scenarios. This intelligent control method not only ensures the uniformity and stability of each spray but also reduces liquid waste and improves ease of use. It ensures that the sprayer actively draws in liquid during use, improving spray efficiency and reducing problems of insufficient liquid absorption due to gravity or low liquid level. In addition, the control button 31 allows users to control the spray according to their needs, making the spray more precise and efficient, avoiding unnecessary liquid waste, and improving the product's intelligence and user experience. The control button 31 is electrically connected to the water pump. When the button is pressed, the water pump is triggered to draw in liquid, which is then sprayed through the spray nozzle 21.

[0029] In one embodiment, such as Figures 2-3As shown, the top of the spray head 2 is inclined, and the top of the spray head 2 is provided with a spray nozzle 21. A bottle cap 4 for sealing the spray nozzle 21 is rotatably provided on one side of the base 201. A hollow pressure block 42 is fixed inside the bottle cap 4 at the position that matches the spray nozzle 21 by a cover block 41. A guide groove 22 is provided on the side wall of the spray head 2 near the side with a lower horizontal height of the spray nozzle 21. The bottom end of the guide groove 22 passes through the bottom end of the spray head 2 and extends out of the base 201. When the pressure block 42 rotates with the bottle cap 4 to seal the spray nozzle 21, the pressure block 42 fits against the spray nozzle 21 from the top of the spray nozzle 21 and slides from the top of the spray nozzle 21 to the bottom of the spray nozzle 21. The pressure block 42 squeezes the liquid remaining at the spray nozzle 21 into the guide groove 22. The top of the spray head 2 is inclined, and the spray nozzle 21 is located at the top of the spray head 2, so that one side of the spray nozzle 21 is higher and the other side is lower. The side of the spray nozzle 21 furthest from the connection point between the bottle cap 4 and the spray head 2 is the lower side, and the side of the spray nozzle 21 closest to the connection point between the bottle cap 4 and the spray head 2 is the higher side. When the spray nozzle 21 is used to spray and moisten the user's mouth, the spray nozzle 21 is sealed by the bottle cap 4. The pressure block 42 rotates with the bottle cap 4, and during the rotation, the pressure block 42 first contacts the top of the spray nozzle 21. Then, as the bottle cap 4 and the pressure block 42 continue to rotate, the pressure block 42 is compressed and squeezes out the liquid located at the spray nozzle 21, allowing the liquid to enter the guide groove 22 and slide along the guide groove 22 to the outside of the spray bottle 1. This reduces the impact of the remaining liquid on the spray nozzle 21 and reduces the impact of the residual liquid after one spray on the next spray. The pressure block 42 also seals the spray nozzle 21, improving the cleanliness and service life of the sprayer.

[0030] In one embodiment, such as Figures 2-3 As shown, the tip of the spray head 2 is tilted away from the connection point between the bottle cap 4 and the spray head 2, and the angle between the tip of the spray head 2 and the base 201 ranges from 30 degrees to 45 degrees. This tilt angle of the spray head 2 allows the spray nozzle 21 to face a direction more consistent with the structure of the human oral cavity, making it easier for the user to aim the spray at their mouth and improving comfort. Simultaneously, the 30-45 degree tilt angle helps reduce liquid backflow, further reducing the possibility of residual liquid at the spray nozzle 21, thus improving the sprayer's effectiveness and hygiene.

[0031] In one embodiment, such as Figures 2-3 As shown, three guide channels 22 are provided on the side of the spray nozzle 21 with a lower height, and the bottom ends of the three guide channels 22 intersect. Using multiple guide channels 22 can effectively increase the drainage channel, allowing the liquid remaining in the spray nozzle 21 to be guided out more quickly, reducing the possibility of liquid accumulation. The design of the intersecting bottom ends of the guide channels 22 helps to concentrate the liquid discharge, prevents liquid from stagnating in the guide channels 22, improves the guiding efficiency, further reduces the amount of liquid residue at the spray nozzle 21, and ensures the hygienic performance of the sprayer.

[0032] In one embodiment, such as Figures 2-3 As shown, the top of the cover block 41 is attached to the spray nozzle 21, and the cover block 41 gradually moves away from the spray nozzle 21 in the direction towards the spray bottle 1. The structural design of the cover block 41 allows it to better fit the spray nozzle 21 when it is closed, thereby effectively preventing the spray nozzle 21 from being exposed and reducing dust or bacterial contamination. The gradual movement of the cover block 41 away from the spray nozzle 21 in the direction towards the spray bottle 1 ensures that the cover block 41 does not affect the flow of liquid in the guide channel 22.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
