Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sprayer, and its purpose is to be able to use a pressurized device for liquid spraying with a simple configuration and large capacity, so that it can be used in remote and high places. The object of the present invention is to provide a sprayer capable of spraying.

As shown in Fig. 1, a conventional sprayer has a main body 1' placed on a container 2', and the two parts 1' and 2' are connected by screwing, and water is sprayed from the direction of soil cultivation. For example, when it rains, raindrops enter the motor cooling intake and exhaust holes,
In order to avoid damaging the equipment by breaking the electrical insulation or causing electric shock to the human body, the power source was a dry cell battery, the motor was made larger than necessary, and the structure was designed without air intake and exhaust holes.

Therefore, it becomes extremely heavy and difficult to handle,
There is a problem that the sprayer cannot achieve its original performance due to the limited output, and since the main body 1' and the container 21 are connected by screwing, it is difficult to put the aqueous solution to be sprayed into the container 2'. In this case, the weight will be directly applied to the threaded joint between the main body 1' and the container 2', and as a result, the threaded joint must be constructed to be quite strong. In addition, if the size of the container 2' is made smaller, the capacity of the container 2' to hold the aqueous solution will decrease, and the weight of the liquid spray pressurizing device installed in the main body 1' cannot be increased too much. , it becomes impossible to use a pressurizing device with a large capacity, and as a result, the liquid has to be replaced many times, and there are problems such as the inability to effectively spray far or high places. It had

The present invention has been made to solve the above-mentioned conventional problems, and one embodiment of the present invention will be described below with reference to FIGS. 2 to 4.

In the figure, reference numeral 1 denotes a container of a sprayer, and the interior thereof is hollow, and an aqueous solution to be sprayed can be introduced through a water supply port 2 and accommodated therein.

In addition, this container 1 has a hole 3 penetrating the side surface of its upper half to form a space, and a handle 4 is provided on the upper side with this space as a boundary.
, and a liquid storage section 5 is integrally formed on the lower side thereof.

A main body 6 is housed in this hole 3.

The main body 6 includes a pump 7 for spraying the aqueous solution under pressure, and a motor 8 for operating the pump 7.

Reference numeral 9 denotes a fan for cooling the motor 8, which takes in outside air through an intake hole 10 and exhausts it through an exhaust hole 11 to cool the motor 8.

12 is a waterproof switch for controlling the motor 8; 13 is a water absorption hose for sucking up the aqueous solution in the container 1; 14
is a filter.

15 and 16 are pressure hoses for guiding the aqueous solution pressurized by the pump 7 to a nozzle (not shown).

Next, the structural relationship between the main body 6 and the container 1 will be described.

As mentioned above, the main body 6 is housed in the hole 3 penetrating the side surface of the container 1, but as shown in the partial cross-sectional view of FIG. 1
The container 1 and the main body 6 are connected by inserting and placing the container 1 into the container 8 .

In this normal positional relationship, the intake and exhaust holes 1 of the main body 6
0.11 is provided so as to face the surface 19.20 parallel to the penetrating direction of the hole 3, as shown in Fig. 3 and Fig. 4, and when viewed from the side as shown in Fig. 3. At least the intake/exhaust holes 10.11 are hidden from view by a portion of the container 1 that connects the handle 4 and the liquid storage section 5.

In addition, the intake and exhaust holes 10 and 11 are connected to a recess 22 on the side surface of the main body 6.
Therefore, if the gap a between the container 1 and the container 1 is small to some extent, it is possible to create a structure that cannot be seen from any direction.

Furthermore, by dividing the structure of the main body 6 into upper and lower sections such as an upper frame 23 and a lower frame 24, it is possible to further prevent water from penetrating inside.

Note that air flows in and out as shown by the arrows in FIG. 4 to cool the motor 8.

25 is a power cord.

As is clear from the above structure, in one embodiment of the present invention, when constructing a container 1 for storing liquid, a hole 3 penetrating the upper side surface is provided to constitute a space, and this space is a boundary. Since the handle 4 is integrally formed on the upper side and the liquid storage section 5 is formed on the lower side, the weight of the liquid in the liquid storage section 5 is directly applied to the handle 4. However, no unreasonable force is applied to the connection between the container 1 and the main body 6, and as a result, it is possible to use a pressurizing device for liquid spraying that has a large capacity, so there is no need to replace the liquid many times. It is capable of spraying liquid to distant or high places.

In addition, the intake and exhaust holes 10 and 11 of the main body 6 are configured to be shielded by the part that connects the handle 4 and the liquid storage part 5, which constitute the container 1, so that rain and the like can be prevented from easily entering the inside of the main body. As a result, it is possible to maintain insulation from internal electrical components, thereby making it possible to prevent accidents such as equipment damage and electric shock.

As described above, according to the present invention, a hole is provided through the upper side surface to form a space, and the handle is integrally formed on the upper side and the liquid reservoir is formed on the lower side with this space as a boundary. The container is equipped with a container, and the main body, which has a built-in pressurizing device that sprays liquid into the space of the container, is removably mounted, so the weight of the liquid in the liquid storage section is not directly applied to the handle. Therefore, even if a large volume of liquid is poured into the container, no undue force will be applied to the connection between the container and the main body.
As a result, it becomes possible to use a pressurized device for liquid spraying that has a large capacity, so it is possible to spray liquid to far or high places without having to replace the liquid many times. This is what you can get.
