[Industrial applications]
The present invention relates to an inhaler using a compressor used for disinfecting and treating a throat.
[0002]
[Prior art]
An inhaler using a compressor (pump) has a configuration shown in FIG. 11, in which 1 is a bottle having an inlet 1a containing a chemical 2, 3 is an atomizing nozzle having a chemical inlet 4, and 5 is a chemical bottle. 1 is a mouthpiece having an outside air introduction port 6 mounted on the mouthpiece 1.
[0003]
[Problems to be solved by the invention]
An inhaler using a conventional compressor having such a structure is configured such that power is supplied to a pump 8, and pressurized air passes through a pneumatic tube 7 and the chemical solution 2 sucked in from a chemical solution inlet 4 by an atomizing nozzle 3 and air. As a result, a mist of the chemical solution is formed, and the air that has flowed in from the outside air inlet 6 is added and discharged from the tip of the mouthpiece 5.
[0004]
However, in this conventional inhaler, the pump 8 used therein must have a large capacity in order to discharge the atomized chemical liquid and make the atomized particles fine, and it is difficult to reduce the size and cost.
[0005]
The present invention provides an inhaler in which the size of the pump is reduced and thereby the overall size is reduced.

[Means for Solving the Problems]
The inhaler of the present invention is a medicinal bottle containing a medicinal solution, a mouthpiece attached to the medicinal solution bottle, and an atomizing nozzle provided with a medicinal solution suction port attached to an air supply port provided in the medicinal solution bottle, An air outlet provided in the mouthpiece was provided, and air from the pressure pump was supplied from both the air inlet provided in the chemical solution bottle and the air outlet of the mouthpiece. As a result, even when a small-capacity pump is used, it is possible to discharge the mist of the fine particle chemical liquid with a sufficient amount of the chemical liquid discharge.
[0007]
In the inhaler of the present invention, both pumps are driven by one drive mechanism with the above-described configuration.
[0008]
Further, the inhaler of the present invention is configured as described above, and is characterized by a pump device for supplying air.
[0009]
That is, the pump device used in the present invention includes a plurality of diaphragm bodies having a pump chamber disposed in a case, and these diaphragm bodies are divided into two sets each including at least one diaphragm body and the remaining diaphragm bodies. Divided, each set has a common valve chamber and a discharge port connected to the valve chamber, and all the diaphragm parts perform a pumping operation by driving one drive mechanism, and a pump of the diaphragm body of each set. The discharge of the air by the action is performed from the discharge port through the common valve chamber, and two pumping actions (supply of air from the two discharge ports) are performed by driving one drive mechanism. For this purpose, a driving section of each diaphragm main body including a diaphragm section and a driving section is attached, and the driving section of each diaphragm main body performs a motion having a phase difference by a rubbing motion of the driving body, whereby each of the diaphragm main bodies is moved. With a pump action having a phase difference of, the air is sent out from the discharge port through the common valve chamber from the pump chamber for each set. Can be supplied.
[0010]
【Example】
Next, an embodiment of the inhaler of the present invention will be described with reference to the drawings.
[0011]
FIG. 1 is a view showing an embodiment of an inhaler according to the present invention. In the figure, reference numeral 1 denotes a bottle having an air supply port 1a and containing a chemical solution 2, 3 an atomizing nozzle having an inlet port 4, and 5 a bottle 1 These structures of the attached mouthpiece are the same as those of the conventional example.
[0012]
Reference numeral 11 denotes a pump, one of which is connected to an air supply port 1 a by an air supply pipe 12, and the other of which is connected to an air supply port 15 provided in the mouthpiece 6 through a flow rate adjustment unit 14 by an air supply pipe 13.
[0013]
In the inhaler of this embodiment, the air pressurized by the pump 11 via the air supply pipe 12 is sent to the atomizing nozzle 3, whereby the chemical solution 2 is atomized. On the other hand, the air sent from the air supply pipe 13 is sent to the mouthpiece 6 from the air outlet 15 at an appropriate flow rate by the flow rate adjusting unit 14, and the atomized chemical solution is discharged from the mouthpiece.
[0014]
In this embodiment, since the air for supplying the atomized chemical solution uses air from a separate pump from the air to atomize the chemical solution to be sent to the nozzle, it is not necessary to use a large-capacity pump. In addition, the size of the pump can be reduced and the size of the inhaler can be reduced.
[0015]
The pump 11 used in this embodiment is composed of two pumps, a pump for sending air to the air supply pipe 12 and a pump for sending air to the air supply pipe 13. These two pumps can be operated by one drive mechanism with one drive source.
[0016]
Hereinafter, an example of a pump including a drive mechanism used in the inhaler of the present invention will be described.
[0017]
2 and 3 show a pump used in the inhaler according to the present invention. In these figures, 21 is a motor, 23 is an eccentric cam fixed to an output shaft 22 of the motor 21, and 24 is an eccentric cam via a ball bearing 25. The connecting rod 26 attached to the core cam 23 is connected to the connecting rod 24 via a connecting shaft 27 and a ball bearing 28 as a connecting body.
[0018]
Pumps 31 and 32 form pump chambers 37 and 38 by casings 33 and 34 and diaphragms 35 and 36 fixed to the casings 33 and 34, respectively. The diaphragms 35 and 36 are attached to both ends of the connecting body 26, respectively.
[0019]
The pump chambers 37 and 38 have intake valves 39 and 40 and exhaust valves 41 and 42, respectively.
[0020]
In the pump device shown in FIGS. 2 and 3, the connecting body 26 reciprocates through the eccentric cam 23, the connecting rod 24, and the connecting shaft 27 by the rotation of the output shaft 22 driven by the motor 21. Due to the change in the volume of the pump chambers 37, 38 based on the deformation of the diaphragms 35, 36 due to this movement, the air is sucked into the pump chamber 37 from the intake port, subsequently discharged from the pump chamber 37 through the exhaust port, and similarly from the intake port. The intake into the pump chamber 38 and the exhaust from the pump chamber 38 are performed.
[0021]
Thus, according to the pump device shown in FIGS. 2 and 3, the driving of one motor 21 causes the pump 31 and the pump 32 to operate.
[0022]
If the pump device shown in FIGS. 2 and 3 is used as the pump 11 of the inhaler of the present invention shown in FIG. 1, the exhaust port of the pump 31 of the pump device shown in FIGS. In addition, if another pump 32 is connected to the air supply pipe 13, two pumps can be operated by one driving mechanism, and the pneumatics for atomizing the chemical solution and the air blowing from the mouthpiece are driven by one drive. It can be done by a mechanism.
[0023]
Next, another example of the pump device used in the inhaler of the present invention will be described. 4 is a plan view of this pump device, and FIG. 5 is a cross-sectional view taken along line AA of FIG. 4. In FIG. 5, reference numeral 51 denotes a motor, 52 denotes an output shaft of the motor 51, 53 denotes a case, and 54 denotes an output shaft. Reference numeral 55 denotes a drive shaft fixed to the collar 54 by being inclined, 56 denotes a drive unit attached to the drive shaft 55, and 57 denotes a diaphragm main body. The diaphragm main body 57 includes a bell-shaped diaphragm portion 58 made of an elastic body and a driving portion 59. In this pump device, four diaphragm bodies 57 of the same size and shape are arranged at equal intervals on the same circumference as shown in FIG. 4 by attaching the drive unit 59 to the drive body 56, respectively. These diaphragm bodies are integrally formed to form four pump chambers 71, 72, 73 and 74. Reference numeral 60 denotes a lid fixed to the upper part of the case 53, and a suction port 61 and a valve 62 are provided for each pump chamber. FIG. 6 is a cross-sectional view taken along the line BB in FIG. 4, and a valve chamber 64 corresponding to the valve body 63 is provided between the two pump chambers 73 and 74. The pump chambers 73a and 74a communicate with two pump chambers 73 and 74 formed by the diaphragm 58, respectively. However, the portions of the grooves 73a and 74a are always closed by the valve body 63 as is clear from FIG. The valve chamber 64 is connected to the discharge port 76. On the other hand, the other two pump chambers 71 and 72 are connected to other valve chambers (not shown) corresponding to other valve bodies through grooves 71a and 72a, and further connected to a discharge port 75.
[0024]
In the pump device shown in FIGS. 4, 5, and 6, the output shaft 52 is rotated by the driving of the motor 51, so that the collar 54 fixed thereto is rotated. The driving body 56 makes a rubbing motion by the motion of the driving shaft. Due to the movement of the driving body 56, the driving portion 59 of each of the diaphragm main bodies 57 attached thereto moves up and down to change the volume of the pump 65, thereby performing the pumping action. In this pumping operation, two diaphragm portions adjacent to one valve chamber act to suck air from the upper suction ports of the pump chambers 71 and 72 to open one valve body and pass through one of the grooves 71a and 72a to pass one of the grooves. Air is sucked from the valve chamber to the discharge port 75 and from the upper suction ports of the pump chambers 73 and 74 by the function of the two diaphragm portions adjacent to the other valve chamber, and the other valve body is opened to open the grooves 73a and 74a. The discharge is performed by discharging the gas from the other valve chambers to the discharge port 76, respectively. These pumping operations are performed on both of the two discharge ports 75 and 76 by driving one drive mechanism including the motor 51, the drive section 55, the drive body 56, and the like, and air is discharged from both of the discharge ports.
[0025]
4, 5 and 6, the inhaler of the present invention can be operated by connecting one of the two discharge ports to the air supply pipe 12 and the other to the air supply pipe 13.
[0026]
As described above, this pump device is configured such that two of the four pump chambers are connected to one discharge port, and the other two pump chambers are connected to another discharge port.
[0027]
The above-described pump device is different from a conventionally known pump device of this type, in which a plurality of pump chambers are divided into two sets and provided on two valve chambers that communicate with the respective pump chambers of the respective sets via valves. A small pump device that is provided with each of the specified discharge ports, and that constitutes a novel pump device in which air is simultaneously supplied from two discharge ports and air is simultaneously transmitted to two places. It is.
[0028]
That is, in FIGS. 4, 5, and 6, the pump chamber 71 and the pump chamber 72 are a first set, and these pump chambers are communicated from the common valve chamber to the discharge port 75 through the groove 71a and the groove 72a. The pump chamber 73 and the pump chamber 74 are a second set, and are communicated from the common valve chamber (a different valve chamber from the valve chamber leading to the discharge port 75) to the discharge port 76 through the groove 73a and the groove 74a. I have. This constitutes a novel pump device that simultaneously supplies air to two different points from two discharge ports with one pump device.
[0029]
It is preferable to use this novel pump device in the inhaler of the present invention.
[0030]
However, in the above pump device, as shown in FIGS. 7, 8, and 9, of the four pump chambers, a combination of three pump chambers and one discharge port, or one pump chamber and one discharge port may be used. .
[0031]
That is, in FIG. 7, the three pump chambers of the upper one pump chamber 71 and the two left and right pump chambers 72 and 74 are made into one set (first set), and these pump chambers are grooves 71a, 72a, 72a, respectively. A lower outlet 74 is connected to the center discharge port 75 with the valve interposed therebetween, and the other one (second set) of lower pump chambers 73 is connected to another outlet 76 with the valve interposed therebetween by a groove 73a. . Connection of these three pump chambers 71, 72, 74 to the discharge port 75 is substantially the same as the embodiment shown in FIGS. 4 and 5 as shown in FIG. 8, which is a cross-sectional view taken along the line CC in FIG. In the same manner as above, the connection of the pump chamber 73 to the outlet 76 is as shown in FIG. 9, which is a cross-sectional view along the line DD in FIG.
[0032]
In this embodiment, the flow rate of air from the discharge port 75 is larger than the flow rate of air from the discharge port 76. Therefore, when this pump is used in the inhaler of the present invention, the discharge port 75 may be connected to the air supply port side of the liquid medicine bottle, and the discharge port 76 may be connected to the air supply port provided in the mouthpiece. That is, the air supplied to the chemical liquid bottle is used for atomizing the chemical liquid and needs to have a large flow rate. Conversely, the air supplied to the mouthpiece does not require a large flow rate. Therefore, when the pump shown in FIG. 7 is used, the flow rate adjustment may not be necessary.
[0033]
Further, a diaphragm pump having three pump chambers can be used as the pump device. That is, as shown in FIG. 10, a diaphragm pump in which three pump chambers are arranged on the same circumference at intervals of 120 ° with respect to the center point of the pump device, and the configuration and operation are three pump chambers. It is substantially the same as the other diaphragm pumps shown, except that the arrangement is slightly different.
[0034]
The diaphragm pump composed of the three pump chambers has a configuration in which discharge ports corresponding to the discharge ports 75 and 76 of the diaphragm pump shown in FIG. 7 are arranged as shown in FIG. Are connected to the two pump chambers 71 and 72 via grooves 71a and 71b via valves, respectively, and the discharge port 76 is connected to the remaining pump chamber 73 (the second set). ing. The connection method between the pump chamber and the discharge port is substantially the same as that of the pump device shown in FIG. 7, and the connection between the two pumps along the line CC in FIG. 10 is along the line CC in FIG. The connection method is substantially the same as that of the sectional view (FIG. 8), and the location of the pump chamber 73 along the line DD in FIG. 10 is the same as the sectional view along the line DD in FIG. 7 (FIG. 9). They can be connected in virtually the same way.
[0035]
In the diaphragm pump device having the pump chambers arranged as shown in this figure, the flow rate of the air discharged from the discharge port 75 is large, and the flow rate of the air discharged from the discharge port 76 is small.
[0036]
The diaphragm pump device shown in FIGS. 7 to 9 and the diaphragm pump device shown in FIG. 10 differ in the amount of air from the two discharge ports as described above. Also, in the case of the diaphragm pumps shown in FIGS. 4 to 6, by changing the volume of the diaphragm portion at the time of the maximum volume for each diaphragm main body, for example, by changing the diameter of the pump chamber, that is, the diameter of the diaphragm portion, It is possible to make the air volume different.
[0037]
Also, by selecting the volume of each pump chamber, it is possible to set the ratio of the amount of air discharged from both discharge ports to a desired value.
[0038]
Further, in the case of the diaphragm pumps having the configurations shown in FIGS. 7 to 9 and 10, the maximum volumes of the respective pump chambers can be different, and the ratio of the amount of air from both discharge ports is set to a desired value. I can do it.
[0039]
Each of the pump devices used in the above embodiments can provide a great effect when used in the inhaler of the present invention.
[0040]
However, in addition to the inhaler of the present invention, there are known those requiring the supply of air from two pumps at the same time. It is also possible to use each pump device for these devices and devices.
[0041]
In particular, the pump devices shown in FIGS. 4 to 6, 7 to 9, and 10 are different from a plurality of pumps such as the inhaler of the present invention by improving this kind of conventional diaphragm pump. One pump device, particularly a plurality of pumps by one drive unit, can be operated for equipment and devices that need to supply air.
[0042]
That is, it has a plurality of diaphragm bodies 57 that comprise a diaphragm section 58 and a driving section 59 arranged in the case 53 and form a pump chamber. These diaphragm bodies 57 (the pump chambers 71, 72,...) Are provided. ) Are divided into at least one set of diaphragm bodies (pump chambers) (first set) and a set of remaining diaphragm bodies (pump chambers) (second set) which are part of each set (first set). A common valve chamber (a common valve chamber of the first set and a common valve chamber of the second set) is provided near each diaphragm main body 57 and connected to the pump chamber via a valve for each of the first and second sets. , Two suction chambers, a suction port 61 connected to each pump chamber 65 via a valve 62, and a common valve chamber 64 of each set (first and second sets). Discharge ports 65 and 66 are provided. The drive portion 59 of the main body 57 is attached to one drive body 56, and the movement of the drive body 56 performs a pumping operation with a phase difference between the discharge ports 65 and 66 (the first set of discharge ports and 66). This is a pump having a novel configuration in which air is discharged from the second set of discharge ports.
[0043]
As described above, the pump device itself has a novel structure and an inventive step, and is very effective if used for a device capable of supplying two systems simultaneously.
[0044]
Therefore, in the pump device shown in FIGS. 4 to 6, the pump device itself is novel and has an inventive step.
[0045]
【The invention's effect】
In the inhaler of the present invention, a pump for supplying air by performing air blowing for forming an air flow for discharging a mist-like chemical solution in addition to the air supplied for forming a mist of the chemical solution is provided. It can be small and the inhaler itself small.
