〔overview〕

The present invention consists of a suction fan that sucks out dust in an ashtray, a storage tank that stores the sucked dust, an exhaust filter means, a pump means that injects water from a water tank into the storage tank, and a suction fan. In an ashtray vacuum cleaner in which a battery for driving a pump means and a pump means are mounted on one trolley, the filter means uses a large number of glass beads and metal cuttings as a filter medium, and the top and bottom surfaces are covered with a metal mesh plate, and the filter means is used for storage. By using a cassette structure fitted into the space above the tank, it is possible to easily clean the filter means from clogging.

[Conventional technology]

At pachinko and other amusement facilities, when players use an intake type vacuum cleaner to collect dust such as cigarette butts and matchsticks that players throw into ashtrays, vacuum cleaners with a structure that completely extinguish the dust are used. Must.

The present inventor has already proposed in Utility Model Application No. 61-180693 an ashtray vacuum cleaner having a structure in which dust is extinguished by moistening it with water stored in a storage tank. Then, in Utility Model Application No. 62-21867, they proposed a structure in which a fountain shower is applied to the sucked dust by means of a pump when it enters the storage tank. We have proposed a system that includes a means to prevent dust from clogging the suction hose that sucks up dust.

Ashtray vacuum cleaners based on each of these ideas are used in play areas equipped with pachinko, mahjong, game machines, etc., and have been well received.

The ashtray contains unspecified materials such as cigarette butts, burning embers, and chewing gum residue, and the storage tank contains water to extinguish unextinguished cigarette butts. The filter means provided between the suction port of the suction fan includes a first filter that removes slightly larger particles of water-wet dust, and a filter that removes smaller fine particles from the air filtered by this first filter. It consists of two sets of filters, including a second filter for removal.

As the filter medium of this first filter, a porous rigid filter medium such as rock wool, steel wool, or folded fine wire mesh has conventionally been used.

[Problem that the invention attempts to solve]

However, in the case where a fountain shower is provided at the entrance of the storage tank to shower the injected dust as described above, the shower does not cover all of the fine dust, so it may fly up into the tank.

In addition, fine dust wet with water is sucked into the first filter, but with the porous rigid filter media mentioned above, if the filter media becomes clogged, it is troublesome to clean it. It was necessary to replace itself.

The present invention solves these shortcomings and can spray the entire injected dust with a fountain shower.
It is an object of the present invention to provide an ashtray vacuum cleaner in which clogging of a filter means can be easily removed.

[Means for solving problems]

The present invention consists of a suction fan with an electric motor, a battery that supplies the driving current for the electric motor, a suction hose whose tip opening approaches the ashtray, and the other end of the suction hose that is attached to store dust injected from the suction hose. A storage tank, a filter means provided between the storage tank and the suction port of the suction fan, a water tank, and a pump means for injecting water from the water tank into the storage tank are integrated into one trolley. In the implemented ashtray vacuum cleaner, the filter means includes a cassette structure that is removably fitted into the space above the storage tank, and this cassette structure communicates with the bottom surface communicating with the space above the storage tank and the suction port. The upper surface of the device is a wire mesh, and the space between the wire meshes on both sides is filled with a large number of glass beads and metal chips.

The storage tank is in the shape of a bucket that is detachably attached to the truck, and the filter means can be installed at a position where it is used as a filter for separating water and dust when the storage tank is removed from the truck and tilted for drainage. can.

[Effect]

By using a large number of glass beads as a filter medium, the surface area can be made extremely large. Moreover, this surface is relatively smooth, and even if cigarette residue or the like adheres to it, it can be easily removed by washing with water.

By using metal cuttings to cover the tops of the glass beads, the glass beads are arranged uniformly and do not move. Therefore, even if there is vibration or inclination due to the use of a vacuum cleaner, the glass beads will be evenly distributed and the filter action will not deteriorate.

When this filter is structured to double as a separation filter, cleaning of the storage tank is simplified.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the structure of a main part of an embodiment of the present invention, and FIG. 2 is a perspective view showing the entire ashtray vacuum cleaner according to this embodiment.

In both figures, a suction fan 1 with an electric motor 1A, a battery 2 that supplies driving current for the electric motor 1A, and a suction hose that brings the tip opening 3A close to the ashtray of the pachinko machine and sucks out dust including cigarette butts from the ashtray. 3, a storage tank 4 having an inlet 4A to which the other end 3B of the suction hose is attached and containing water 4B to store the dust 22 to be injected, and the storage tank 4 and the suction port 1B of the suction fan 1. a first filter 5 and a second filter 6 as filter means provided between the water tank 7 and the water tank 7 as a pump means for injecting the water in the water tank into the storage tank 5. A water pump 9 that delivers water to a nozzle 8 provided inside the storage tank 4 via a backflow prevention electromagnetic valve 9A is mounted on one cart 10 including a handle 10A and a caster 10B.

Here, the feature of the present invention is that the filter means is arranged in a bracket 4D in the space above the storage tank 4.
The first filter 5 includes a cassette-structured housing 5A that is removably fitted into the housing 5, and the bottom surface of the housing 5 that communicates with the upper part of the storage tank 4 and the upper surface that communicates with the suction port are provided with a large number of small holes. 5B, with small holes 5 between the mesh plates on both sides.
Glass beads 5C with a diameter larger than the inner diameter of B and continuous annular small metal cutting chips 5 with rust resistance
The reason is that D is filled.

In this case, the storage tank 4 is in the shape of a bucket that is detachably attached to the trolley 10, and the first filter 5 is attached to the upper part of the bucket-shaped storage tank 4, as shown in FIGS. 1 and 2. When the water in the tank is drained out of the tank by tilting the tank, the dust mixed in the water is filtered out through the small holes on the bottom of the housing 5A and remains in the tank. It has a semi-cylindrical shape such that a portion thereof comes into contact with a part of the inner surface of the storage tank 4. Although the bracket 4D is not particularly shown, in this case, the inner surface of the tank and the semicircular side surface of the casing are kept in close contact with each other, and when only the casing is removed, this close contact is released. It has a known shape.

The upper lid 4B of the storage tank 4 includes a gasket 4C for keeping the contact area airtight with the upper end of the tank and the upper end 5E of the center side of the housing 5A when the lid 4B is attached. ing. Therefore, air mixed with dust is injected from the suction hose 3 as shown by arrow A, is filtered by the first filter 5 as shown by arrow B, and is inserted into the two holes 4E provided in the lid 4B. Two pipes 6 of tray 6A
D is sent to the second filter 6 as shown by arrow C (see FIG. 2).

The glass beads of the filter medium of the first filter have a smooth surface and are spherical, so their surface area ratio is large. Therefore, when the dust is immersed in water, nicotine and other leaching components tend to adhere to the surface of the glass beads, and they also easily dissociate when rinsed with water. Therefore, cleaning of the filter medium becomes easy.

In addition, the metal cuttings themselves have a filtering effect, but they can also cover the glass bead debris in an irregularly shaped layer, so vibrations or tilting of the trolley can cause the glass bead layer to collapse and remove the debris. It is possible to prevent the glass bead layer from becoming non-uniform and reducing the filtration effect of the glass bead layer.

As described above, after the water in the storage tank 4 has been drained, the housing 5A is removed, the remaining dust is transferred to a specified container, and the inside is washed. The first filter shakes the housing in water to remove the dust adhering to the inside, and then shakes it again to drain the water. Inside the housing, the glass beads gather at the bottom and the metal cutting chips appear at the top.

If the dust adhering to these glass beads or metal cuttings does not immediately separate into the water, a spare one is installed in the storage tank, and the dirty ones are immersed in water to separate the dust. In this case, the separation can be facilitated by immersing the housing in warm water or a detergent solution containing a surfactant.

[Effect of idea]

As explained above, according to the present invention, it is easy to collect and discharge the dust accumulated in the storage tank, and to clean the filter means, so that a large number of ashtrays installed in a crowded play area with a large number of players can be used. This has the effect of realizing an ashtray vacuum cleaner that can process dust in a short amount of time.
