Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a gas sustained release device that can gradually vaporize and diffuse liquid into the air for purposes such as aroma, deodorization, or sterilization. It is.

[Conventional technology]

For example, for fragrances that use liquid, there are two methods: storing the liquid fragrance in a container body and vaporizing the liquid while adjusting the opening of the fragrance part at the mouth of the container body, or creating a fragrance using the container body. A dispersion member made of felt or the like is provided at the mouth of the device, one end of the suction member is connected to the dispersion member, and the other end is placed in the liquid aromatic agent, and the liquid aromatic agent is sucked up to the dispersion member using capillary phenomenon. There are methods such as bringing the dispersion member into contact with air to gradually vaporize the liquid fragrance to create a fragrance, and many products using these methods are commercially available.

Such a method is also widely used when liquid deodorizers or liquid sterilizers are vaporized and released for the purpose of deodorization or sterilization.

[The problem that the idea attempts to solve]

As mentioned above, the conventional method of using liquid for purposes such as fragrance, deodorization, and even sterilization and vaporizing this liquid to achieve the desired purpose is to directly transfer the liquid to the container body. Since the liquid contained in the container body is directly or indirectly vaporized and diffused into the air, there are no problems when it is placed indoors or the like.

However, for example, when heating and cooling a room, if you want to add fragrance or deodorize at the same time as cooling or warming air,
The use of a container body containing the liquid directly as described above has problems such as leakage of the liquid during use and difficulty in assembling the container body containing the liquid into an air conditioner.

Therefore, it is currently not practical to use liquid fragrances and chemicals in air conditioners such as air conditioners and heaters for purposes such as fragrance, deodorization, insecticide and pest extermination, and even sterilization.

In view of the current situation, this idea was developed to provide fragrance, deodorization, sterilization, etc. using a liquid that can be easily and easily incorporated into air conditioners such as air conditioners and heaters, as well as for use in general households. The purpose of the present invention is to provide a sustained gas release device.

[Means to solve the problem]

In order to achieve the above object, the gas sustained release device of this invention has a porous member for holding and supplying liquid loaded in a sealable container body having a hollow part, and a porous member for holding and supplying liquid in the hollow part. A core member having a large number of capillary tube parts formed in the hollow part is disposed, and both ends of the core member are inserted into the container body from the wall surface forming the hollow part, and the ends of the core member and the porous member are brought into contact with each other. ,
The liquid impregnated into the porous member is guided into the hollow part through the core member, and is vaporized and diffused.

In this invention, the container body has a hollow part,
There are no particular restrictions on its shape, size, material, etc. as long as it can be sealed, but it is preferable to have a ring-like shape as a whole with a hollow part formed in the center.

The porous member for holding and supplying the liquid loaded into the container body is made of, for example, felt, cotton, or urethane foam, and the amount of liquid that can be impregnated into the porous member is 90 to 95% of its own volume. However, taking into consideration the unlikely event of liquid leakage, it is more preferable that the amount of liquid that can be held in the porous member be approximately 8 times 90 to 95% of the porous member's own volume.

The liquid to be impregnated into this porous member is a liquid aromatic agent, a liquid deodorant, or a liquid medicine for purposes such as fragrance, deodorization, and sterilization, and one or more of these liquids may be used. It is also possible to use a mixture.

If the core member disposed in the hollow part of the container body has a large number of capillary tubes formed on the outer periphery,
The material and specific shape are not limited at all, but for example, a irregularly shaped monofilament made of a thermoplastic synthetic resin such as polyacetal, nylon, or polyolefin with many capillary tubes formed on the outer periphery of the shaft core. It is preferable to use a porous fibrous structure in which fibers are bundled together, or a porous body in which inorganic or organic microspheres are bonded or sintered, which have capillary action.

In addition, if the capillary force of this core member is not larger than the capillary force of the porous member for holding and supplying the liquid (the capillary force necessary for holding the liquid), the capillary force from the porous member to the core member will smoothly flow. No liquid is supplied to the

The amount of vaporized liquid retained in the porous member through the core member depends on the diameter of the core member, the size of the capillary tube of the core member, the number of core members disposed in the hollow part, and the flow around the core member. Although it can be arbitrarily adjusted by appropriately selecting the air flow rate, it is preferable to design so that the amount of vaporized liquid is 5 to 100 mg/h.

In addition, when the liquid held in the porous member consists of multiple components with different evaporation rates, the components with slower evaporation rates will initially be concentrated in the capillary portion of the core member, but since an equilibrium state will then be reached, this does not pose any particular problems in practice. However, concentration can be prevented by impregnating the core member with a specified amount of the component with a slower evaporation rate before use.

[Effect]

The sustained gas release device of this invention houses a porous member impregnated with a liquid suitable for aroma, deodorization, sterilization, etc. in a container body, and a porous member is placed in a hollow part formed in the container body on the outer circumferential surface. A core member having a large number of capillary portions is provided, and each end of the core member is inserted into the container body from the wall surface forming the hollow portion, and the end of the core member and the porous member are brought into contact with each other. Therefore, the liquid impregnated into the porous member is guided into the hollow part through the core member and vaporized into the air due to the difference between the capillary force of the porous member and the capillary force of the core member. .

Therefore, the amount of vaporized liquid is determined by the diameter of the core member,
It can be easily and easily adjusted by appropriately selecting the size of the capillary tube of the core member, the number of core members disposed in the hollow portion, and the flow velocity of the air flowing around the core member.

In addition, since the porous member is impregnated with a liquid suitable for the purpose of vaporization and dissipation, and this is vaporized and dissipated into the air through the core member, there are no restrictions on the installation direction, and it can be easily and easily attached to various types of equipment. It is possible to incorporate

It consists of

In this embodiment, the container body 2 is made of a synthetic resin material, has a hollow part 3 in the center, and is composed of a ring-shaped container with an open top and a ring-shaped lid 4 that seals the opening. A plurality of holes 6 for inserting and holding the core member 9 are provided at approximately the center of the inner circumferential wall 5 of the container body 2 forming the hollow portion 3, and a plurality of holes 6 for inserting and holding the core member 9 are provided at equal intervals. One small diameter air introduction hole 7 is provided in the section.

The porous member 8 accommodated in the container body 2 includes:
It is composed of two ring-shaped felt sheets, and when loaded into the container body 2, an air passage 5a is formed inside the inner peripheral wall 5 by communicating with the air introduction hole 7 formed in the inner peripheral wall 5. Therefore, it is preferable to use felt having a width narrower than the ring width of the container body 2.

The core member 9 is composed of a deformed monofilament made of a thermoplastic synthetic resin material such as polyacetal, nylon, or polyolefin, and is molded by an extrusion molding machine using a die having a diameter similar to the cross-sectional shape shown in Fig. 3. It is molded by molding.

This core member 9 has an axis 10, and the axis 1
0 to 6 protruding pieces 11 are formed to protrude radially at equal intervals, and a narrow gap 12 is formed between adjacent protruding pieces 11, 11, and the same rotation is formed on the side wall of each protruding piece 11. Branch-like pieces 13 and 14 having different lengths are formed at a predetermined interval in the direction, and the gap 12 is further subdivided to form a capillary tube between the adjacent protruding pieces 11 and 11. be.

The core member 9a shown in FIG. 4 shows another embodiment, and like the core member 9, the core member 9a is
Seven protruding pieces 11a are arranged radially on the outer periphery of this axis 10a at equal intervals, and each protruding piece 11a
A narrow gap 12a is formed therebetween, and large and small spherical protrusions (not labeled) are formed on the side walls of each protruding piece 11a, thereby making the entire gap 12a a capillary tube.

Unless the capillary force of the core members 9, 9a is stronger than the capillary force of the porous member 8 that holds the liquid, it will be difficult to lead the liquid impregnated into the porous member 8 to the core member and vaporize it. Become.

As shown in FIGS. 1 and 2, six core members 9 having such a cross-sectional shape are intersected in a star shape in the hollow portion 3 formed in the center of the container body 2. The ends of each core member 9 are inserted into the container body 2 through the holes 6 provided in the inner circumferential wall 5 of the container body 2 forming the hollow portion 3, and the tips thereof are inserted between the two porous members. By sandwiching it between 8 and 8, it is attached and held to the container body 2.

In this way, after the core member 9 is set in the container body 2, the porous member 8 is impregnated with a liquid aromatic agent, and the lid 4 is attached to the container body 2 with adhesive or the like and sealed for use. The liquid aromatic agent impregnated into the porous body 8 is guided from the end of the core member 9 to the hollow part 3, and the liquid is vaporized from the side and gradually dissipated into the air, so it can be used in air conditioning equipment. By partially installing the device, it is possible to mix the fragrance into the gas blown into the room.

It should be noted that this example is merely for illustrative purposes, and does not limit the shape or material of the container body, porous member, core member, etc.

[Effect of idea]

The sustained gas release device of this invention has a porous member impregnated with a liquid suitable for the purpose of use in a sealable container body, and a large number of capillary tubes on the outer periphery of the hollow part formed in the container body. The ends of the shaft members are inserted and held into the container body from the wall surface of the container body forming a hollow portion, and the porous member is impregnated by the capillary force of the shaft member. Since the liquid is guided into the hollow part and vaporized and dissipated, there is no risk of liquid leakage compared to conventional fragrance devices that directly contain the liquid, so the installation location and direction can be changed. It has the characteristic that there are no restrictions, and it has become possible to simply and easily incorporate it into air conditioning equipment, etc.

In addition, the amount of liquid vaporized and dissipated can be easily adjusted by adjusting the diameter of the core member, the number of core members installed, the amount of air flowing around the core member, etc., which increases the degree of freedom in design. This has been greatly improved and has many practical advantages, such as making it possible to design a container body that suits the purpose of use.
