Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more specifically to an ultrasonic atomization device for stomatology. Background Art

[0002] The ultrasonic atomization device uses the high-frequency vibration energy of ultrasound to break up the liquid into tiny particles, and converts electrical energy into mechanical energy through an ultrasonic transducer, causing the piezoelectric ceramic to deform and vibrate, which then acts on the liquid medium, causing the liquid to be continuously refined as the piezoelectric ceramic continues to vibrate, eventually forming a mist.

[0003] Patent No. CN111938852A discloses an oral cleaning spraying device for stomatology, comprising a box assembly (1), a piston assembly (2) arranged in the box assembly (1), and a support assembly (3) arranged outside the box assembly (1), wherein the box assembly (1) comprises a box (11), wherein the box (11) is provided with a first through hole (111), and the support assembly (3) comprises a connecting frame (31), wherein one end of the connecting frame (31) is aligned with the first through hole (111) and is fixedly connected to the side of the box (11).

[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention is provided with an atomizer body, which is conducive to atomizing the drug liquid into uniform particles with a diameter of 3-10 microns, which is convenient for deep cleaning and disinfection of fine areas of the wound. The atomized particles generate a vortex in the drainage tube, which increases the turbulence and shear force. This rotational motion helps to cut the liquid into smaller and more uniform droplets, thereby improving the atomization quality, and can remove the condensed droplets in the compression chamber and the vortex chamber, ensuring the smoothness of the internal channel of the drainage tube, and improving the circulation efficiency of the atomized particles in the overall process. Finally, the atomized particles are sprayed out by the spherical nozzle to clean the patient's oral cavity, increase the humidity of the oral mucosa, and relieve dryness. It is especially suitable for patients with xerostomia. The tiny atomized particles of the drug liquid can penetrate into every corner of the oral cavity, effectively remove dirt and bacteria, and keep the oral cavity clean.

[0017] 2. The present invention is advantageous in adjusting the spray angle and spray pressure of the spherical nozzle by providing a spray pressure regulating mechanism and a fine-tuning mechanism. Adjusting the spray angle can clean more of the inside of the oral cavity, and can more easily clean difficult-to-clean locations, thereby expanding the scope of use, ensuring that the atomized particles are accurately delivered to the target area in the oral cavity, improving the therapeutic effect, and reducing unnecessary drug waste. In addition, during the spraying process, it is important that the spray pressure can be adjusted by the spray pressure regulating mechanism, and the movable design of the cone head slider in the transformer cylinder can directly affect the spray pressure of the atomized particles. The size of the spray pressure determines the size, shape, and distribution of the sprayed droplets. Appropriate spray pressure can make the droplets finer and more uniform, thereby improving the spraying effect and controlling the distribution range of the liquid. During the spraying process, the flight distance and diffusion range of the droplets are closely related to the spray pressure. By adjusting the spray pressure, the distribution range of the liquid can be accurately controlled to ensure that the liquid can evenly cover the target area, more comprehensively clean the inside of the oral cavity, flexibly control the spray range and intensity, and meet different wound care needs.

[0018] 3. The present invention is provided with a heating ring and a filter, which is conducive to preheating and heating the drainage tube, keeping the drainage tube at a stable working temperature, so as to reduce the generation of droplets due to atomization condensation caused by temperature differences, and ensure the stable flow of atomized particles. The filter can filter the moisture in the gas entering the filter chamber from the external environment, avoid excessive moisture entering, resulting in excessive humidity inside the drainage tube, promoting condensation of atomized particles, and further ensuring the stable flow of atomized particles.

[0019] 4. The present invention is provided with a power-off mechanism, which is beneficial for pushing the travel switch through the extended end of the electric push rod when the water level gauge detects that the water level of the medicine liquid in the medicine storage tank is too low, and then automatically cutting off the power supply and shutting down the atomizer body to prevent the atomizer body from being overheated and damaged, protecting the internal components and extending the service life.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The ultrasonic atomization device for stomatology involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0030] Reference Figure 1-Figure 8 The present invention provides an ultrasonic atomization device for stomatology, comprising a shell 1, a handle 101 is arranged on the lower side of the shell 1, a medicine storage tank 2 is fixedly installed on the upper side of the shell 1, an atomizer body 3, a drainage tube 4, a transformer tube 6 and a fine-tuning mechanism 9 are arranged in the shell 1, a liquid outlet of the medicine storage tank 2 is connected to the atomizer body 3, the drainage tube 4 is arranged between the atomizer body 3 and the transformer tube 6, a heating ring 14 is fixedly connected to the surface of the drainage tube 4, a nozzle shell 7 is arranged at the end of the atomizer body 3, a spherical nozzle 701 is rotatably arranged in the nozzle shell 7, a spray pressure regulating mechanism 8 is installed on the transformer tube 6, the spray pressure regulating mechanism 8 is used to control the spray pressure of atomized particles, the fine-tuning mechanism 9 is used to adjust the spray angle of the spherical nozzle 701, a controller 10 is fixedly connected in the handle 101, a plurality of control buttons 1001 are arranged on the side of the controller 10, and a power-off mechanism 11 is arranged on the controller 10, and the liquid water level in the medicine storage tank 2 is monitored by the power-off mechanism 11 to automatically cut off the power supply.

[0031] The drainage tube 4 is provided with a filter chamber 401, a volume expansion chamber 402, a diameter reduction chamber 403, a swirl chamber 405 and a compression chamber 406 from right to left. The filter chamber 401 is connected to the output end of the atomizer body 3. The filter chamber 401, the volume expansion chamber 402 and the diameter reduction chamber 403 are directly connected. The swirl chamber 405 is located at the outer layer of the diameter reduction chamber 403. The diameter reduction chamber 403 and the swirl chamber 405 are connected by opening a flow groove 404. The swirl chamber 405 is directly connected to the compression chamber 406.

[0032] In this embodiment, it is necessary to specifically explain that: the housing 1 and the handle 101 adopt an ergonomic streamlined design, which is light in weight, comfortable to hold, and easy to operate with one hand; the medicine storage tank 2 is used to store disinfectant liquid, which can be specifically iodine liquid; the medicine storage tank 2 is made of PP medical-grade polymer material, which has the characteristics of transparency, corrosion resistance, and high-temperature disinfection resistance, and has high strength and rigidity, and can meet some application scenarios that require container strength; the medicine storage tank 2 is equipped with a scale 201, which can directly observe the water level of the liquid medicine in the medicine storage tank 2, so as to accurately control the amount of liquid medicine and reduce waste; the atomizer body 3 is used to atomize the liquid medicine, and is mainly composed of a high-performance ultrasonic transducer, a piezoelectric ceramic, and an air pump, and converts electrical energy into mechanical energy through high-frequency vibration to atomize the liquid medicine. The uniform particles are 3-10 microns in diameter, which are convenient for deep cleaning and disinfection of fine areas of wounds. The atomized liquid medicine is sprayed into the drainage tube 4, which is used to guide the flow of atomized particles. The atomized particles are easy to condense and produce droplets in ordinary pipes. The drainage tube 4 can eliminate the condensed droplets during the flow of atomized particles. The atomized particles enter the expansion chamber 402 from the filter chamber 401. The internal diameter of the expansion chamber 402 gradually expands and then shrinks. The diameter reduction has a pressurizing effect. The atomized particles after preliminary pressurization enter the reduced diameter chamber 403. The focus is on the design of the through-flow groove 404. The through-flow groove 404 is provided with a plurality of grooves, which are evenly distributed on the inner wall of the reduced diameter chamber 403, and the through-flow groove 404 is inclined. The atomized particles enter the swirl chamber from the through-flow groove 404. 405, due to the further pressurization to generate high-speed swirl, the atomized particles of the high-speed swirl are accelerated to enter the compression chamber 406. The swirl causes the atomized particles to rotate in the swirl chamber, which increases the turbulence and shear force. This rotational motion helps to cut the liquid into smaller and more uniform droplets, thereby improving the atomization quality, and can remove the condensed droplets in the compression chamber 406 and the swirl chamber 405, ensuring the smoothness of the internal channel of the drainage tube 4, and improving the circulation efficiency of the atomized particles in the overall process. Then, the atomized particles enter the transformer tube 6 through the screw joint 601, and are finally sprayed out by the spherical nozzle 701 to clean the patient's oral cavity. Compared with gargling or directly spraying water for cleaning, the atomized particles can increase the humidity of the oral mucosa and relieve dryness, which is particularly suitable for For patients with xerostomia, tiny atomized particles of liquid medicine can penetrate into every corner of the mouth, effectively remove dirt and bacteria, and keep the mouth clean. The atomized particles directly act on the oral mucosa, which can inhibit the growth and reproduction of bacteria or viruses, reduce inflammatory reactions in the mouth, and effectively relieve oral pain, such as pain caused by oral ulcers, through the action of local anesthetics. The drug ingredients in the atomized particles can increase local blood circulation, accelerate cell repair and regeneration, and help wound healing. For patients with respiratory problems such as coughing and sputum, the atomized particles can help dilute the sputum and humidify the airway, thereby reducing cough symptoms and promoting sputum discharge. In addition, the overall gun-shaped holding structure of the device is convenient for users to operate and is more suitable for use in stomatology.

[0033] Preferably, a heating ring 14 is installed on the surface of the drainage tube 4 to preheat and heat the drainage tube 4 and keep the drainage tube 4 at a stable working temperature to reduce the generation of droplets caused by atomization condensation due to temperature differences and ensure stable flow of atomized particles.

[0034] The main difference between the present embodiment and the prior art is that the present embodiment adopts the cooperation of the nozzle shell 7 and the spray pressure regulating mechanism 8, specifically: the structure of the spherical nozzle 701 located in the nozzle shell 7 is spherical, and the nozzle shell 7 can support the spherical nozzle 701 to rotate to a certain extent. When in use, the short rod 902 is pushed to rotate by the extended end of the micro electric telescopic rod 901, and the short rod 902 drives the spherical nozzle 701 to rotate slightly, so as to adjust the spray angle of the spherical nozzle 701. Since the oral cavity sizes of different patients are different and the mouth opening ranges are also different, adjusting the spray angle can clean more of the inside of the oral cavity, and it is easier to clean the difficult-to-clean positions, thereby expanding the scope of use, ensuring that the atomized particles are accurately delivered to the target area in the oral cavity, improving the treatment effect and Reduce unnecessary waste of medicine, and during the spraying process, it is important that the spray pressure can be adjusted through the spray pressure regulating mechanism 8. The movable design of the cone head slider 801 in the transformer cylinder 6 can directly affect the spray pressure of the atomized particles. The size of the spray pressure determines the size, shape and distribution of the sprayed droplets. Appropriate spray pressure can make the droplets smaller and more uniform, thereby improving the spray effect and controlling the distribution range of the liquid. During the spraying process, the flight distance and diffusion range of the droplets are closely related to the spray pressure. By adjusting the spray pressure, the distribution range of the liquid can be accurately controlled to ensure that the liquid can evenly cover the target area, more comprehensively clean the inside of the oral cavity, flexibly control the spray range and intensity, and meet different wound care needs.

[0035] The above structure is the main structure of this embodiment, which solves the problem of oral cleaning, and the atomizing medicine liquid of the nebulizer body 3 is an existing structure. The specific structure and connection method of the medicine storage tank 2 and the nebulizer body 3 are not described in detail in this embodiment. In addition, the rotation of the spherical nozzle 701 also belongs to the existing technology. Therefore, this application does not make detailed limitations.

[0036] Reference Figure 2 A filter 5 is fixedly installed in the filter cavity 401, and a desiccant is filled in the filter 5.

[0037] In this embodiment, it should be specifically explained that the filter 5 is mainly composed of desiccant filling, which can filter the moisture in the gas entering the filter chamber 401 from the external environment, avoid excessive moisture entering, resulting in excessive humidity inside the drainage tube 4, and promote condensation of atomized particles, thereby ensuring stable flow of atomized particles.

[0038] Reference Figure 4 and Figure 8A screw joint 601 is provided on the upper side of the transformer cylinder 6 , and the screw joint 601 is fixedly connected to the outlet of the compression chamber 406 , and the nozzle shell 7 is fixedly connected to the outlet of the transformer cylinder 6 .

[0039] In this embodiment, it should be specifically explained that: the screw joint 601 is connected to the compression chamber 406, the atomized particles enter the screw joint 601 from the compression chamber 406, then enter the transformer cylinder 6, and finally are sprayed out by the spherical nozzle 701, and the diameter of the end of the transformer cylinder 6 gradually decreases, thereby increasing the kinetic energy of the flow of the atomized particles and ensuring the spray effect.

[0040] Reference Figure 4 and Figure 6 The spray pressure regulating mechanism 8 includes a cone head slider 801, a long rod 802, a servo motor 803, a ball screw 804, a screw sleeve 805 and a reinforcement sleeve 806. The cone head slider 801 is slidably connected to the transformer tube 6, and a sealing ring 807 is embedded on the circumferential surface of the cone head slider 801. One end of the long rod 802 is fixedly connected to the cone head slider 801, and the other end of the long rod 802 slides through the transformer tube 6 to extend outward. The servo motor 803 is fixedly connected to the handle 101, the ball screw 804 is fixedly connected to the output end of the servo motor 803, the screw sleeve 805 is threadedly connected to the circumferential surface of the ball screw 804, and the reinforcement sleeve 806 is fixedly connected between the screw sleeve 805 and the long rod 802.

[0041] In this embodiment, it is necessary to specifically explain that: the end of the cone head slider 801 is a cone structure, the long rod 802 is used to connect the cone head slider 801 and the screw sleeve 805, the long rod 802 is restricted to move linearly in the housing 1, and when in use, the control button 1001 controls the servo motor 803, and the output end of the servo motor 803 drives the ball screw 804 to rotate, the ball screw 804 drives the screw sleeve 805 to move linearly, the screw sleeve 805 drives the reinforcement sleeve 806 to move linearly, the reinforcement sleeve 806 drives the long rod 802 to move linearly, and finally drives the cone head slider 801 to move linearly. The line moves. When the cone head slider 801 moves, the pressure of the atomized particles sprayed from the transformer cylinder 6 changes accordingly. The size of the spray pressure determines the size, shape and distribution of the sprayed droplets. Appropriate spray pressure can make the droplets smaller and more uniform, thereby improving the spray effect and controlling the distribution range of the liquid. During the spraying process, the flight distance and diffusion range of the droplets are closely related to the spray pressure. By adjusting the spray pressure, the distribution range of the liquid can be accurately controlled to ensure that the liquid can evenly cover the target area, and the spray range and intensity can be flexibly controlled to meet different wound care needs.

[0042] Reference Figure 6 and Figure 8The fine-tuning mechanism 9 includes a micro electric telescopic rod 901 and a short rod 902. The bottom of the micro electric telescopic rod 901 is connected to the inner wall of the housing 1 through an ear shaft, one end of the short rod 902 is fixedly connected to the spherical surface of the spherical nozzle 701, and the other end of the short rod 902 is rotatably connected to the extended end of the micro electric telescopic rod 901.

When in use, the micro-electric telescopic rod 901 can be controlled by the control button 1001, and the short rod 902 is pushed to move by the extended end of the micro-electric telescopic rod 901. The short rod 902 drives the spherical nozzle 701 to rotate a certain angle, so that the spray angle of the spherical nozzle 701 can be directly adjusted. Adjusting the spray angle can clean more of the inside of the oral cavity, and it is easier to clean difficult-to-clean positions, thereby expanding the scope of use, and ensuring that the atomized particles are accurately delivered to the target area in the oral cavity.

[0044] Reference Figure 4 The power-off mechanism 11 includes a travel switch 1101, an electric push rod 1102 and a water level gauge 1103. The travel switch 1101 and the electric push rod 1102 are both fixedly connected to the handle 101. The travel switch 1101 is connected to the controller 10 by electrical signals. The water level gauge 1103 is fixedly connected to the connection between the medicine storage tank 2 and the atomizer body 3. When the water level gauge 1103 monitors that the liquid level in the medicine storage tank 2 is too low, the extended end of the electric push rod 1102 is driven to push the travel switch 1101 to automatically disconnect the power supply.

[0045] In this embodiment, it should be specifically explained that: the water level meter 1103 can monitor the water level of the medicine liquid in the medicine storage tank 2 in real time, the travel switch 1101 is a commonly used limit switch, and can control the switch of the atomizer body 3. When the water level meter 1103 detects that the water level of the medicine liquid in the medicine storage tank 2 is too low, the travel switch 1101 is pushed by the extended end of the electric push rod 1102, and then the power is automatically cut off to turn off the atomizer body 3, so as to prevent the atomizer body 3 from being damaged by overheating, protect the internal components, and extend the service life.

The lighting lamp 13 is a high-brightness LED lamp, which provides a shadowless light source and is conducive to precise visual operation. The scale ruler 201 can directly observe the water level of the medicine solution, which is conducive to the user to accurately control the amount of medicine solution in advance and reduce waste.

[0050] Working principle of the present invention:

[0051] The main problem solved by this embodiment is: the atomized medicine liquid is used by the atomizer body 3 without direct contact with the wound, which solves the problem of pain caused by direct flushing, avoids the risk of blood clots falling off, and is conducive to the natural healing of the wound. The adjustable spray mode can accurately control the distribution range of the liquid to ensure that the liquid can evenly cover the target area, more comprehensively clean the inside of the oral cavity, and solves the problem that mouthwash cannot comprehensively clean.

[0052] The specific steps are as follows:

[0053] S1. Preparation: Add an appropriate amount of liquid medicine to the medicine storage tank 2, fix the medicine storage tank 2 on the housing 1, and check whether the battery 12 has sufficient power;

[0054] S2, start cleaning: put the nozzle shell 7 into the oral cavity, aim the spherical nozzle 701 at the area to be cleaned, and then start the atomizer body 3 to start working. The liquid medicine is atomized into fine particles of 3-10 microns through the atomizer body 3. The atomized particles are sprayed to the area to be cleaned through the drainage tube 4, the transformer tube 6 and the nozzle shell 7;

[0055] S2-1, drying and heat preservation: when the atomized particles pass through the filter chamber 401, the filter 5 is used to dry the atomized particles to reduce the moisture in the atomized particles and prevent the atomized particles from condensing, and the heating ring 14 is started to keep the drainage tube 4 at a stable working temperature;

[0056] S2-2, swirl: When the atomized particles enter the swirl chamber 405 from the reduced diameter chamber 403 through the flow groove 404, a high-speed swirl is generated under the action of the internal air pressure. The atomized particles of the high-speed swirl can carry away the droplets on the inner walls of the swirl chamber 405 and the compression chamber 406;

[0057] S3, disinfection process: aim the spherical nozzle 701 at the target area, hold the housing 1 and move the atomized particles to evenly cover the wound and the surrounding tissues. The atomized particles can penetrate into the small gaps of the wound to complete comprehensive sterilization and disinfection;

[0058] S3-1. Adjust the spray pressure: During cleaning, the ball screw 804 is driven to rotate by the output end of the servo motor 803, and the ball screw 804 drives the screw sleeve 805 to move linearly, the screw sleeve 805 drives the reinforcement sleeve 806 to move linearly, the reinforcement sleeve 806 drives the long rod 802 to move linearly, and finally drives the cone head slider 801 to move linearly. At this time, the pressure of the atomized particles sprayed from the transformer cylinder 6 changes accordingly. The size of the spray pressure determines the size, shape and distribution of the sprayed droplets, and the spray range and intensity are flexibly controlled to meet different wound care needs and clean the dead corners inside the oral cavity;

[0059] S3-2, adjusting the angle: during cleaning, the short rod 902 is pushed to rotate by the extended end of the micro electric telescopic rod 901, and the short rod 902 drives the spherical nozzle 701 to rotate slightly, thereby adjusting the spray angle of the spherical nozzle 701. Adjusting the spray angle can clean more of the inside of the oral cavity, and it is easier to clean the difficult-to-clean positions, ensuring that the atomized particles are accurately delivered to the target area in the oral cavity;
