Description

[Detailed Description of the Invention] Industrial field of application The present invention is an aerosol sprayer that can be used separately for spraying spraying an insecticide from a needle tube inserted into a tatami mat and for applying it to a tatami mat or a jutan surface with a coating member. Regarding the device.

2. Description of the Related Art Conventionally, as this type of aerosol injection device, for example, the one described in Japanese Utility Model Laid-Open No. 62-75860 is known.

The aerosol injection device described in the publication is provided with a coating member in the length direction of the outer surface of the aerosol container, and a needle tube is provided in the same direction side as the coating member, and a passage communicating with the coating member and the needle tube and the ejection pipe of the aerosol container. Are connected by way of a switching valve, and are separately used for spraying in which the pesticide is sprayed from a needle tube inserted into the tatami mat and for applying the pesticide on the tatami mat or the surface of the jutan.

However, in the conventional aerosol injection device, since the needle tube projects to the same side as the application member, the needle tube becomes an obstacle when applying the pesticide to the tatami mat or the surface of the jutan with the application member, so the needle tube Had to be removed one by one, and there was a problem that usability was poor.

Therefore, an object of the present invention is to improve the usability by using the needle tube without removing the needle tube during application and by independently using the application and injection.

Means for Solving the Problems In order to achieve the above object, the present invention is provided with a needle tube that is inserted into the tatami mat, and an application member that slides into contact with the tatami or a Jutan surface, and ejects the needle tube and the application member and the aerosol container. An aerosol injection device in which a passage connecting to a pipe is connected via a switching valve, and is used for spraying to spray from a needle pipe and coating to apply with a coating member, wherein the coating member is the outer surface length of the aerosol container. Provided in a direction to support the needle tube above the ejection tube,
The push valve connected to the jet pipe is provided with the switching valve, and the push buttons are provided so that they can be separately pushed by two pushing portions, and when the switching valve is pushed by one pushing portion, the passage to the needle tube is closed. It is characterized in that the passage to the member can be opened, and the passage to the needle tube can be opened and the passage to the application member can be closed when the passage is pushed by another pushing portion.

Action When the aerosol container is inverted, the needle tube is inserted into the tatami mat and the push button is pushed in with one push-in part, the ejection pipe retracts into the aerosol container and opens the ejection valve, and the switching valve closes the passage to the application member. The passage to the needle tube is opened, and the aerosol content is supplied to the needle tube and sprayed inside the tatami mat.

On the other hand, when the aerosol container is laid down sideways without pushing the needle tube and the push button is pushed by the other pushing part, the ejection pipe retracts into the aerosol container and opens the ejection valve, and the switching valve closes the passage to the needle tube and the coating member. To open the passage for supplying aerosol content into the coating member, and the aerosol content oozes to the surface of the coating member.
