Description

  The present invention relates to a diffuser that diffuses a fragrance component, for example.

  Conventionally, a fragrance device is known as a diffuser that volatilizes a fragrance component (for example, Patent Document 1).

In this fragrance device, a fragrance storage cassette that stores fragrance is set, and it is configured to mix the fragrance component with the air taken in from the air intake and discharge it from the air outlet provided on the side surface. .
JP 2000-189508 A

  However, in such a diffuser, there is a limit to increasing the size of the air outlet due to the structure in which the opening is formed on the side of the case to form the air outlet.

  That is, when the air outlet is extended in the circumferential direction, the strength of the case is reduced. For this reason, complication of a structure cannot be avoided, and the new problem that an assembly becomes complicated will arise.

  The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a diffuser capable of forming a large air outlet without causing a complicated structure.

In order to solve the above-mentioned problem, in the diffuser according to claim 1 of the present invention, in the diffuser in which the liquid medicine is housed and the volatilized medicine is discharged from the outlet provided on the side, An upper member that forms the upper part with the outlet as a boundary and a lower member that forms the lower part are configured as separate members, and the lower member and the upper member are connected by a column to form the air outlet between the members. The column is formed integrally with the upper member, and a screw screwed from the lower surface side of the lower member is screwed into the tip surface while the tip surface of the column is in contact with the lower member. The upper member is fixed to the lower member, a fin disposed between the upper member and the lower member is set as the air outlet, and the column is inserted into a through hole provided in the fin. The fin is fixed to the lower member It was fixed equity to.

  That is, the air outlet provided in the side surface is formed between the upper member and the lower member connected by the pillar, and is larger than the case where the air outlet is formed by forming the opening on the side surface. A blower outlet can be formed.

  At this time, the column is formed integrally with the upper member, and a screw screwed in from the lower surface side of the lower member is screwed onto the tip surface while the tip surface of the column is in contact with the lower member. By entering, the upper member and the lower member are fixed.

Therefore, without increasing the number of parts, size of the blow outlet is achieved.

In the diffuser according to claim 2, a large-diameter portion constituting a proximal end side and a small-diameter portion constituting a distal end side having a smaller diameter than the large-diameter portion are set in the column, and the small-diameter portion is inserted. while projecting the cylindrical portion to the lower member, in a state in which the small diameter portion of the pillar is fixed to the lower member is inserted into a through hole provided in said fins, said cylinder and said larger diameter portion of the pillar The fin was sandwiched and fixed between the two parts.

  That is, at the time of assembly, the small diameter portion provided in the column of the upper member is inserted into the through hole of the fin, and the small diameter portion is inserted into the cylindrical portion protruding from the lower member. Then, a screw is screwed in from the lower surface side of the lower member, and the screw is screwed into the front end surface of the column in contact with the lower member. Then, the upper member is fixed to the lower member via the pillar, and an outlet is formed between the two members, and the fin is disposed between the upper member and the lower member.

  At this time, a large-diameter portion is formed on the proximal end side of the small-diameter portion, and the fin through which the small-diameter portion is inserted is fixed in a state of being sandwiched between the large-diameter portion and the cylindrical portion. . In this state, the fin is maintained in a separated state from the upper member when the large-diameter portion abuts, while being kept away from the lower member by abutting the cylindrical portion.

  As described above, in the diffuser according to the first aspect of the present invention, since the air outlet is formed between the upper member and the lower member connected by the pillar, the opening is formed on the side surface and the air outlet is formed. Compared with the case where it forms, a big blower outlet can be formed.

  And the said blower outlet is formed by the two members of the said upper member and the said lower member with which the said pillar was integrally formed, and this lower member is in the state which contact | abutted the front end surface of the said pillar to the said lower member The upper member and the lower member can be fixed to form the air outlet simply by screwing the screw screwed in from the lower surface side into the distal end surface.

Thus, without causing complication of the increase and the structure of the parts, it is possible to achieve an increase in the size of the blowing outlet. Therefore, assembly is also easy.

  Further, in the diffuser according to claim 2, the small diameter portion provided in the column of the upper member is inserted into the through hole of the fin and then inserted into the cylindrical portion of the lower member from the lower surface side of the lower member. The upper member can be fixed to the lower member and a fin can be disposed between the two members simply by screwing the screwed screw into the tip end surface of the column that is in contact with the lower member.

  At this time, a large-diameter portion is formed on the proximal end side of the small-diameter portion, and the fin through which the small-diameter portion is inserted is fixed in a state of being sandwiched between the large-diameter portion and the cylindrical portion. it can. In this state, the fin is maintained in a separated state from the upper member by abutting the large diameter portion, and is maintained in a separated state from the lower member by abutting the cylindrical portion. Thereby, the blowing space can be secured at the upper and lower portions of the fin.
