改良に係る。[Detailed description of the invention] [Industrial application field] This invention is a plastic pressurizing pump cylinder that is removably screwed onto a plastic spray liquid container at the enlarged diameter section provided at the base of the cylinder. The present invention relates to an improvement of a portable pressure accumulating sprayer of the above type, which has a relatively large capacity and is used for agricultural or horticultural purposes.
上記形式の蓄圧式噴霧器の従来例としては本出
願人の出願に係る実開昭53−40512号公報に示さ
れたものも従来品の欠点を持つた代表例の一つで
ある。
As a conventional example of the pressure accumulating type sprayer of the above type, the one disclosed in Japanese Utility Model Application Publication No. 53-40512 filed by the present applicant is also one of the representative examples which has drawbacks of conventional products.

ポンプのシリンダを噴霧液容器から取りはずし噴
霧液容器の上方開口から噴霧液を補充した後再び
前記シリンダの基部を噴霧液容器にねじ込んでい
た。 These conventional products do not have a dedicated injection port for refilling the spray liquid into the spray liquid container, so when refilling the spray liquid, the cylinder of the pressure pump must be removed from the spray liquid container. After replenishing the spray liquid from the upper opening of the spray liquid container, the base of the cylinder was again screwed into the spray liquid container.

リンダと噴霧液容器とがねじで結合されているの

大径部はその径が大き過ぎ、またシリンダの径は
その径が小さ過ぎて、大きな容器を固定した状態
でシリンダ側に所要大きさの捻回力を与えること
は極めて困難である。 In the first place, the reason why the pressure cylinder and the spray liquid container are connected with screws in this type of sprayer is that the cylinder is manufactured separately by injection molding and the container by blow molding. Due to this, once the cylinder and container are connected as a pressure-accumulating atomizer, they should always be kept airtight and watertight as an atomizer, except in special cases such as cleaning the inside of the container. It is. Further, since the threaded connection between the container and the cylinder does not take into account frequent loosening and tightening, operation is extremely difficult and inconvenient. In other words, the diameter of the enlarged diameter portion at the base of the cylinder is too large, and the diameter of the cylinder is too small, making it extremely difficult to apply the required amount of twisting force to the cylinder side while a large container is fixed. be.
さらに噴霧液を補充する都度頻繁にねじ部をゆ
るめたり締め付けたりすることはねじ部を摩損さ
せる原因となり噴霧器の機能を永く維持すること
ができない。 Furthermore, frequently loosening or tightening the threaded portion every time the spray liquid is replenished causes wear and tear on the threaded portion, making it impossible to maintain the function of the sprayer for a long time.

であり、且つ接着手段は強度的にも好ましくなく
短筒部が剥離したりしてその結果噴霧液の漏洩す
る原因ともなつていた。 Furthermore, in conventional products, the short cylindrical part for inserting and holding the liquid guiding pipe for guiding the spray liquid to the spray nozzle, the short cylindrical part for installing the safety valve, etc. are all made of plastic as appropriate for the spray liquid container. In order to construct each of these short cylindrical parts into a spray liquid container, first, the short cylindrical parts are planted and fixed by adhesive means on the outside of the upper perforation part which is bored in the appropriate position of the spray liquid container. Ta. Such a working means is extremely inefficient, and the adhesive means is not favorable in terms of strength, and the short tube portion may peel off, resulting in leakage of the spray liquid.

る。 Furthermore, in the present invention, the above-mentioned short cylindrical parts 7, 8, and 9, which are integrally formed to project from the cylinder base 3 integrally formed at the end of the cylinder 2, are All of the cylinder axes passing through the center of the parts lie within one common plane passing through the center axis of the pressurizing cylinder 2, and by doing so, when these parts are integrally molded with plastic material. The use of two separate molds allows for extremely efficient molding. In connection with this, the hooking parts 6, 6 of the shoulder belt, which are protruding parts other than the short cylinder parts, have a diameter of the cylinder base perpendicular to one common plane passing through the central axis of the cylinder 2 mentioned above. Preferably, they are located opposite in direction. (See Figures 1 and 4) To briefly describe the operation of this invention,
Hold the grip 15 shown in Figures 1 and 2 and press the piston rod 1.
The pressure inside the spray liquid container 1 is increased by the action of the piston 13 reciprocating in the cylinder 2 which raises and lowers the spray liquid container 1 via a check valve (the part shown in FIG. 2, 16). Although not shown, a spray operating device consisting of a spray nozzle and an operation part such as a push button is connected to the tip of the liquid guide pipe 18, and if necessary, the push button provided on the handle of the device can be pressed. By pressing, a desired spray can be ejected from the nozzle. When not in use, the spray actuating device is held by locking the locking portion of the grip provided with the push button with a holding hook 20 provided at the top of the cylinder 2.

The accompanying drawings show embodiments of the invention, and FIG.
In the case where the cylinder base, which is integrally and continuously formed below the pressurizing air pump, has a shape in which a large diameter cylindrical part is connected to the bottom of a conical part that widens downward, the upper part of the pump cylinder and the lower part of the spray liquid container A sloped view showing only the main parts with the shoulder belt and a part removed.
In addition, Figure 2 shows the vertical cross section taken along the line A-A in Figure 1, that is, the axis of the pump cylinder and the installation of a safety valve for holding the liquid guide pipe for injecting the spray liquid formed at the base of the cylinder. It is a vertical cross-section of the main part cut along one common plane including the cylinder axis of each short cylinder part for the purpose of the present invention. Figure 3 shows an example of a safety valve. (A) in the figure shows a case in which a safety valve with a valve body enclosed in a cylindrical valve case is housed and held in a short cylindrical part at the base of the cylinder, and (A) in the figure shows a case in which a safety valve with a valve body enclosed in a cylindrical valve case is housed and held in a short cylindrical part at the base of the cylinder. ) shows the cross section of the case where the short cylinder part is used as it is as a valve cylinder of a safety valve. Moreover, FIG. 4 illustrates the shape of the cylinder base and the relationship of each short cylinder part to the base. Note that, in each of the above figures, the spray actuating device, which consists of a spray nozzle connected to the tip of the liquid conduit and an operating section such as a push button, is not shown. In the drawings, 1 is a spray liquid container, 2 is a cylinder, 3 is a cylinder base, 4 is a conical part, 4' is a flat part,
5', 5' are enlarged diameter parts, 6 is a hook part, 7' is a closing lid,
7, 8, and 9 are short cylinder parts for spray liquid injection, liquid guide pipe holding, and safety valve equipment, respectively; 13 is a piston;
14 is a piston rod, 15 is a grip, 16 is a check valve device, 17 is a liquid riser pipe, 18 is a liquid guiding pipe, 19 is a shoulder strap, and 20 is a holding hook.
