ものである。 In the central space 13 of the diaphragm 7 having a dish shape, there are an inlet passage 14 and a discharge passage 15 bored in the base 3b.
and open. A rubber plate-shaped suction valve body 16 is disposed at the opening of the suction passage 14 so as to close the opening, and one end of the suction valve body 16 is held between the base 3b and the flange 7a of the diaphragm 7. , the other end is left free and acts as a valve. Since the suction path 14 is an introduction path for outside air, a filter 1 is installed at the suction port.
Cleaning air is introduced through the air filter 7. On the other hand, the discharge passage 15 is provided so as to open at the center of the central space 13, and its outlet is connected to the spacer 1.
It communicates with the air passage 19 of No. 8. A rubber plate-shaped discharge valve body 20 is disposed at the outlet of the discharge passage 15 so as to close the outlet, one end of the discharge valve body 20 is held between the base 3b of the frame 3 and the spacer 18, and the other end is held between the base 3b of the frame 3 and the spacer 18. The portion has a free end that can move into the air guide path 19 and functions as a valve. The air conduction path 19 communicates with a conduction portion 22 of the nozzle block 21. The nozzle block 21 is connected to the spacer 18 via an O-ring 23.
The airtightness is maintained to prevent compressed air from leaking from the air guide path 19. A conical space is provided at the end of the conductive portion 22 of the nozzle block 21, and an air nozzle 24 is passed through and held at the top of the conical space, so that the tip of the air nozzle 24 projects into an ejection space 25 provided in the nozzle block 21. This air nozzle 24 blows out compressed air sent from the air pump 2 as a high-speed jet flow, and sucks up liquid from a water suction nozzle 26 provided near its tip. The water suction nozzle 26 is connected to a water suction pipe 28 that is provided substantially perpendicular to the axis of the air nozzle 24 and inserted to the bottom of the storage tank 27 . The storage tank 27 is a container molded from an elastic material, and its outer periphery is covered with a hard cover body 29 so as not to lose its shape when the liquid is stored therein. It's summery. Bottom part 29a of cover body 29
A recess 30 is provided in the bottom 2 of the storage tank 27.
A portion of 7a enters into the recess 30 and is recessed. Therefore, when a strainer 31 is attached to the tip of the water suction pipe 28 inserted into the storage tank 27 and the lower end of the strainer 31 is pressed against the bottom 27a, the bottom 27a is pushed by the strainer 31 and a recess 32 is formed. This recess 32 is located in the storage tank 27.
This is done to reduce the amount of residual liquid in the tank.
本体ケース４の先端には噴霧カバー３３を螺着

広がりながら飛散する。 Next, the operation of the liquid sprayer having the above configuration will be explained. The motor 1 is operated by operating a power switch 34 attached to the outer surface of the main body case 4, and the air pump 2 is operated. When the air pump 2 enters the suction stroke, that is, when the diaphragm 7 moves to the right in the figure, the suction valve body 16 opens and the discharge valve body 20 closes, so air is removed from the suction passage 14 through the filter 17. will be introduced.
When the central space 13 of the diaphragm 7 is filled with air and the air pump 2 then enters the discharge stroke, that is, as the diaphragm 7 moves to the left in the figure, the discharge valve body 20 opens, and at the same time the suction valve body 16 opens. When closed, air is discharged into the air guide path 19. The discharged air becomes compressed air and is vigorously blown out from the air nozzle 24. This air with a high flow rate creates a negative pressure at the tip of the water suction nozzle 26 due to the Ventury effect, and the liquid in the storage tank 27 is transferred to the water suction pipe 28.
suck it up through. The sucked up liquid exits from the tip of the water suction nozzle 26 and at the same time is ejected as a mist by compressed air from the air nozzle 24. The mist is dispersed while being spread at an appropriate angle by the spray cover 33.

つた。 However, in the conventional air pump of a liquid sprayer, during the discharge stroke, the diaphragm does not come into contact with the base wall surface of the central space into which air is introduced, and a gap volume is created in the central space. If this gap volume is large relative to the pump volume, in the case of a compressed body such as air, it will not be possible to discharge it, and the pump will not function as an air pump. Further, the compressed air discharged by the reciprocating motion of the diaphragm has pulsations, and no means have been taken to eliminate this pulsation, so that a constant spray state cannot be obtained.
本発明は、効率を向上させ、しかも脈動をなく

Since the liquid sprayer has already been described, the air pump will now be described. The air pump 35 has a main body case 3 which is the base of the pump.
6, a diaphragm 38, a suction valve body 39, and a discharge valve body 40. The base 37 is
It penetrates the air suction passage 41 and the discharge passage 42 and opens into the pump air chamber 43 . Pump air chamber 43
is a space formed between the base 37 and the diaphragm 38, and the inner wall of the base 37 is the space formed between the diaphragm 38.
Diaphragm 3 is formed to match the shape of diaphragm 3.
When 8 is at the end of the discharge stroke, the pump air chamber 4
3 is the narrowest. At the end of the discharge stroke, the diaphragm 38 has a substantially M-shaped cross section and is fixed by applying a support ring 44 to a flange portion 38a provided on its outer peripheral edge. Further, the diaphragm 38 is connected to a motor 46 via a motion converter 45 and a shaft 46

ることになる。 The suction valve body 39 is an elastic member such as a rubber plate arranged to close the opening of the suction passage 41, and one end thereof is connected to the base 37 and the flange 3 of the diaphragm 38.
8a, and the other end is used as a free end to function as a valve. The discharge valve body 40 is connected to the pump air chamber 4
3, and its outlet communicates with the air guide path 48 of the spacer 47. A discharge valve body 40 made of an elastic material such as a rubber plate is disposed at the outlet of the discharge passage 42 so as to close the outlet, one end of the discharge valve body 40 is held between the base 37 and the spacer 47, and the other end is held between the base 37 and the spacer 47. The portion has a free end that can move into the air conduction path 48 to function as a valve. base 3
Since the diaphragm 38 has an M-shaped cross section at the end of the discharge stroke, the diaphragm 38 has a thick part 37a in a part between the air chamber 43 and the discharge valve body 40.
A space 49 is provided in the base 37 from the discharge valve body 40 side using the space 7a. The opening of this space 49 is covered with the discharge valve body 40 and is sealed, thereby functioning as an accumulator. That is, the diaphragm 38
The compressed air pushed out and discharged into the air guide path 48 hits the elastic discharge valve body 40 and pushes the discharge valve body 40 into the space 49, so that the discharge valve body 40 and the space 49 are separated. It will act as an accumulator.

In addition, since the space that is created based on the shape of the diaphragm makes effective use of the thick wall part and the discharge valve body that is in contact with this space acts as an accumulator, the structure of the accumulator is simple and does not require any special installation space. Moreover, it is compact, and the generation of pulsation in the discharged compressed air can be prevented.
