Description

[Detailed explanation of the idea] This invention relates to an inhaler.

The basic structure of a suction device that suctions liquid as mist droplets for dry mouth or colds, etc. consists of a nozzle, a pump, and a liquid supply tank, but conventional products have separate nozzles and pumps. It was a method of constructing parts and then assembling them by connecting them together.

Therefore, not only does the number of connected parts including the airtight member increase, but also the connections must be made so that there is no air leakage, which makes the connection work difficult and poses a problem in that the reliability of the seal is questioned.

Therefore, the object of this invention is to provide an inhaler with improved seal reliability and reduced number of parts.

An embodiment of this invention is shown in FIGS. 1 to 3.

That is, in this inhaler, a connection board 2 is provided in the middle part of a main body cover 1 in the shape of a cylinder with a bottom, the lower part thereof is used as a battery storage space 3, and the bottom cover 4 is connected to dry batteries 5a, 5b for the motor.
are loaded in opposite directions.

A switch button 7a is provided on the side wall 6 of the main body cover 1, and a water amount display window 7 is provided on the side wall 6 located above the connection board 2.
b is open.

- As shown in Fig. 2, the excellent operation part A includes a nozzle base 8 and a pump base 9 that form a communication path 10 and are connected together, and a motor base 11 is attached to the pump base 9, and a water supply tank is attached to the nozzle base 8. The part 12 and the spray generating part 13 are connected together, and the nozzle 14, the diaphragm 15, and the motor 16 are fixed to the respective corresponding parts, and the motor 16-
An eccentric shaft 17 is interlocked and connected between the and diaphragm 15, while a spray guide 18 is attached to the spray generator 13, and a water tank 19 is removably held in the water tank mounting part 12 via an O-ring 20. There is.

In the figure, 21 is an intake valve of the pump chamber 22, 23 is an exhaust valve, and the diaphragm 15 is driven by the motor 16.
When the pump operates, air is sucked in from the intake valve 21 when the top dead center is reached, and when the bottom dead center is reached, the intake valve 21 closes and the exhaust valve 23 opens, and the air passes through the communication path 10 to the nozzle. 14.

Furthermore, 24 in the figure is a water absorption hole communicated with the nozzle tip;
Reference numeral 5 denotes a tube which absorbs water from the water supply tank 19 as air is injected, mixes the air into a spray state, and injects the mixture.

Therefore, in the air circulation process, since there are no connecting parts as in the past, there is no seal reliability problem associated with the connecting work, and a complete seal can be achieved, and the number of connected parts can be reduced and assembly can be facilitated.

The operating section A is integrally covered with a split cover 26, and an accent ring 29 is attached to the step 28 that abuts the opening 27 of the main body cover 1. As shown in FIG. 3, guide ribs 30 and guide grooves 31 are formed to facilitate attachment and detachment of the water tank 19 and to prevent damage to the O-nong 20.

Reference numeral 32 denotes an electrical and mechanical connection portion between the operating portion A and the main body cover 1.

As described above, in the inhaler of this invention, the nozzle base, pump base, motor base, and water tank mounting part are integrally formed and held in the actuating part, and the water tank is attached to the water tank mounting part in a protruding state. Since the water supply tank and the motor housing of the operating part are detachably attached to the main unit cover, interconnection of the nozzle, diaphragm pump, and motor is extremely simple, reducing the number of parts and eliminating air leaks caused by the pump. Therefore, the spray characteristics do not change significantly.

Furthermore, when attaching and removing the water tank, the pump and nozzle are not separated, and by integrating the motor, diaphragm pump, nozzle, and water tank holding part, the mutual positioning of the parts can be ensured, improving the reliability of the seal. .

Furthermore, even when the spray barrel is tilted upward for ease of use (see FIG. 1), since the holding portions of each part are integrally formed, no special means for holding the spray cylinder and sealing it is required.
