Description

Handheld atomizer

Technical Field

The utility model relates to an atomizer, in particular to a handheld atomizer.

Background

Nebulizers are commonly used in the following patients: 1. xerostomia patients have dry mouth due to less secretion of their salivary glands; 2. in uremic patients, local gland atrophy and hypofunction of the oral cavity are caused by toxin accumulation, gland secretion is reduced, and the oral cavity is dry; 3. the patient who performs nasal surgery has to breathe through the oral cavity due to nasal cavity filling after the surgery, and the dry mouth can be caused. Therefore, in the medical field, nebulizers are commonly used as tools for wetting the mouth and nasal cavities of patients.

Atomizers commonly used in hospitals are based on the venturi jet principle. The venturi jet principle is as follows: the compressed air is utilized to form high-speed air flow through the fine pipe orifice, negative pressure is generated near the high-speed air flow, so that the air flow has an adsorption effect, liquid or other fluid near the adsorption effect is sprayed onto the barrier together, and the liquid drops are splashed to the periphery under high-speed impact to become vaporific particles to be sprayed out from the air pipe. At present, an oxygen pipe is connected with a venturi pipe to provide an air source for atomizing liquid in the venturi pipe, but the mode is required to be used on or near a sickbed, and proper activity exercise is required for patients to improve blood circulation and promote rehabilitation, so that the mode cannot meet the requirements of the patients.

In this embodiment, the valve plate 31 is made of hard rubber, so that sealing is facilitated, and gas is prevented from passing through a gap between the valve plate 31 and the interior of the valve body 34. The number of ventilation holes 35 in this embodiment may be one, two, three or other numbers.

The valve 3 in fig. 4 to 6 is provided with diagonal hatching at portions other than the valve plate 31, and is only for convenience of expression, and is not limited to the material of the valve 3.

If a large mist discharge amount is desired, the handle 32 on the shaft lever 33 is rotated, the shaft lever 33 and the valve plate 31 are simultaneously rotated by 90 degrees, so that the width direction of the valve plate 31 is parallel to the axial direction of the connecting pipe, the internal state of the valve 3 is shown in fig. 6, and the gas from the shell 5 completely enters the gas inlet 22 of the venturi tube 2 and then enters the narrow opening 25 of the venturi tube 2 to atomize the liquid, and the atomization amount is maximum; if it is desired to reduce the atomization amount, the shaft 33 and the valve plate 31 are rotated 90 ° in the opposite direction, or rotated 90 ° in the original rotation direction, so that the width direction of the valve plate 31 is parallel to the radial direction of the connecting pipe, see fig. 5, and the gas portion coming out of the housing 5 enters the air inlet 22 of the venturi tube 2 through the air vent 35, and then enters the throat 25 of the venturi tube 2 to atomize the liquid, and the atomization amount is minimum.

Here, as shown in fig. 5, when the valve plate 31 is rotated to have its width direction parallel to the width direction of the valve body 34, the left edge of the valve plate 31 abuts right against the left side wall inside the valve body 34, and the right edge of the valve plate 31 abuts right against the right side wall inside the valve body 34. Under the action of no external force, the valve plate 31 can not deviate from the position independently only under the action of air flow, and the problem that the mist output is influenced due to the change of the position of the valve plate 31 is avoided.

It should be noted that, in this embodiment, the valve 3 may also be a plug-in structure, and the length of the valve body 34 is at least 2 times the outer diameter of the connecting pipe.

If the mist is required to be discharged in a large amount, the shaft rod 33 is pulled out towards the outside of the valve body 34, so that the circular valve plate 31 is separated from the diameter position of the connecting pipe, and the gas in the connecting pipe completely enters the venturi tube 2 along the inner diameter of the connecting pipe; if the amount of mist to be discharged is small, the shaft rod 33 is inserted into the valve body 34, and the circular valve plate 31 completely blocks the orifice of the connecting pipe, so that gas can only pass through the vent holes 35 on the valve plate 31, thereby reducing the throughput of gas and further reducing the amount of mist to be discharged.

When the present embodiment is used, the switch 6 on the housing 5 is turned on, and the housing 5 delivers gas from the gas outlet 51 to the venturi tube 2 by means of the gas pump, and the gas atomizes the liquid in the liquid chamber 23 via the fine slit 25 in the venturi tube 2, and is then sucked into the mouth and nose through the atomizing cover 1.
