Abstract

PURPOSE:To feed a great volume of air through slight stroke by arranging first and second continuous pump chambers while lapping in compressing direction. CONSTITUTION:First and second pump chambers 1, 2 of diaphragm shape arranged while being lapped in compressing direction will show approximately C- shaped cross-section as a whole, where the leading edge sections are communicated to the blow-out port 3. While first and second stopper boards 4, 5 are arranged respectively on the upper face of pump chamber 1 and the lower face of pump chamber 2 to facilitate the compressing operation of each pump chamber 1, 2. Pressing of stopper boards 4, 5 will cause pressing of second pump chamber 2 through first press chip 8 while second press chip 10 will press the first pump chamber 1 to feed air in each pump chamber through the blow-out port 3 to the outside.

Description

[Detailed description of the invention] (Technical field) The invention relates to manual pumps.

(Back volume technology) Conventionally, in order to send a large volume of air with a manual pump, it was necessary to operate the manual pump with a large stroke.
It has the disadvantage that it is not easy to use and requires a lot of labor.

(Objective of the invention) Does the present invention have the above drawbacks? ]l: This was proposed to solve the problem.The purpose is to form first and second pump chambers that communicate with each other, and to stack them in the compression direction. To provide an easy-to-use manual pump that can send air of up to 100 liters of air.

(Disclosure of invention) Hereinafter, the present invention will be explained along with the drawings.

1 to 5 show a first embodiment of the present invention, and in the figures, 1 and 2 are provided overlappingly in the compression direction n,
The first and second pump chambers are bellows-shaped, and these pump chambers 1.2 are generally U-shaped as a whole, and communicate with each other at their tips 6 (i), leading to the Suita mouth 3V. In addition, the upper part of the first pump chamber 1 and the upper part of the second pump chamber 2 and the presser plates 4 and 5 of #43J2 are
is arranged in each pump chamber, making it easy to compress the pump chambers 1 and 2.
As shown in FIG. 2, an intake valve 6 is provided at the end of the second engine chamber 2 through the second holding plate 5. At both ends of the first holding plate 40 in the width direction, first operating pieces 7 are vertically disposed, and at the lower ends of these operating pieces 7. First suppression piece 8 that presses two sides of the second pump chamber 2
f12 is attached.

On the other hand, the second operation piece 9 is provided at both ends of the second holding plate 50, and the upper end of these pieces has a function of suppressing the first Honda chamber l. The second pressing piece 10 is
3. To perform this operation, press the VC holding plates 4 and 5 in the direction of the arrow in the figure from the state shown in Figure 4. The first pressing piece 8 is the second pump chamber, and the second pressing piece 10 is the first bonfu chamber 1. r: Press each pump chamber 1, 217'3? P air [blowout [13

(Effects of the Invention) As described above, the present invention is characterized in that the first and second pump chambers communicate with each other and are arranged overlappingly in the compression direction of the Honda chamber. In the second 41111J-piece of the first workpiece, which simultaneously controls the pump chambers,
As shown in Fig. g8 (example) and Fig. 5p (invention), a four-capacity pump chamber'Z 1 (la,): J,, engineering In the case of 2 and (2a), the effect is to reduce the stroke weight to J- at 1tM6, or to send the amount of air at 1tM6. be. 1,000 k, the stroke is small, but the small manual Honda and the E2 have excellent operability and the effect that the 1,000 yen can provide with the ease of use.
