Description

  The present invention relates to a chemical solution supply apparatus for supplying various chemical solutions.

  Generally, a device such as a container having a pump mechanism is used as a device for supplying various chemical solutions. As a chemical solution supply apparatus provided with such a pump mechanism, for example, there is an invention as described in Patent Document 1 below.

JP 11-293742 A

  As in the chemical solution supply apparatus disclosed in Patent Document 1, a device having a mechanism portion such as a pump mechanism inside is in contact with the chemical solution contained in the container, and the chemical solution is used over a long period of use. There was a risk that the mechanism part in contact with the surface would corrode.

  Further, when the members move up and down in the mechanism portion, each member is in contact with the chemical solution, so that there is a risk of energy loss or the like when supplying the chemical solution.

  The present invention has been made to solve such problems, and does not include any mechanism part that contacts the chemical solution, and therefore causes corrosion or energy loss of the mechanism part due to the chemical solution. It is an object of the present invention to provide a chemical solution supply device that does not have any problem.

  The present invention has been made to solve such a problem. The invention according to claim 1 includes a storage container 1 that stores a chemical solution, and a gas phase portion 2 in which the chemical solution in the storage container 1 does not exist. Air supply means for supplying air to the container, and when the liquid level of the chemical liquid is pushed down by the air supplied by the air supply means, the chemical liquid is introduced to supply the chemical liquid to the outside of the container 1 And a chemical supply pipe 7.

  According to a second aspect of the present invention, in the chemical liquid supply apparatus according to the first aspect, the air supply means is connected to the air pump 4 and the air pump 4 and protrudes to the gas phase portion 2 in the container 1. It is an air supply pipe 3.

  The invention described in claim 3 is characterized in that, in the chemical liquid supply apparatus according to claim 1 or 2, the air supply means is configured to operate with a timer.

  The present invention includes a container that contains a chemical solution as described above, an air supply unit that supplies air to a gas phase portion in which the chemical solution does not exist, and air supplied by the air supply unit. When the liquid level of the chemical liquid is pushed down, the chemical liquid supply pipe is provided to flow the chemical liquid and supply the chemical liquid to the outside of the storage container. By supplying air to the gas phase portion, the pressure in the gas phase portion gradually increases, and thereby the liquid level of the chemical solution is pushed down.

  When the liquid level of the chemical solution is pushed down in this way, a part of the chemical solution flows into the supply pipe, and a volume of the chemical solution corresponding to the lowered liquid level is supplied to the outside of the container through the supply pipe. The Rukoto.

  In this case, since the driving force for pushing down the liquid level of the chemical liquid and supplying the chemical liquid to the outside of the storage container through the supply pipe is generated only by the air blown into the gas phase part of the storage container, a general pump Unlike the chemical solution supply device with the mechanism inside the container, the mechanism part never comes into contact with the chemical solution. Therefore, there is no problem such as corrosion of the mechanism part due to the chemical solution. There is an effect that the possibility of causing an energy loss or the like in the driving force for supplying the chemical liquid is remarkably reduced as compared with the chemical liquid supply apparatus provided in the container.

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

  As shown in FIG. 1, the chemical liquid supply apparatus of the present embodiment includes a storage container 1 for storing a chemical liquid, and an air supply pipe 3 for supplying the gas phase portion 2 in the storage container 1 into the air. When the liquid level 6 of the chemical solution 5 in the container 1 is pushed down by the air pump 4 connected to the air supply pipe 3 and the air blown from the air supply pipe 3, the chemical solution 5 is caused to flow. And a chemical solution supply pipe 7 for supplying the container 1 to the outside.

  The storage container 1 includes a container body 8 and a lid body 9, and the lid body 9 is fixed to the container body 8, whereby the interior of the storage container 1 becomes a sealed space, and the chemical solution 5 is stored in the storage container 1. In this state, the portion in which the chemical solution 5 is stored becomes the liquid phase portion, and the other portion becomes the gas phase portion 2.

  One end 3 a side of the air supply pipe 3 is connected to the air pump 4, and the other end 3 b side of the air supply pipe 3 penetrates the lid body 9 of the storage container 1, and the air in the storage container 1 It is in a state of appearing in the phase part 2. That is, the other end 3 b side of the air supply pipe 3 is not immersed in the chemical solution 5.

Further, one end 7a side of the chemical solution supply pipe 7 is immersed in the chemical solution 5, and the other end side of the chemical solution supply pipe 7 is extended to a supply destination of the chemical solution although not shown.

  The air pump 4 is configured to be operated by a timer, whereby the supply amount of the chemical liquid from the chemical liquid supply pipe 7 is the operating time of the air pump 4, more specifically, the operating time of the motor that drives the air pump 4. It can be prepared.

  The type of the chemical liquid is not particularly limited, and various chemical liquids such as various detergents, hand detergents installed in bathrooms, urine stone removers, and the like can be used.

  And when using the chemical | medical solution supply apparatus which consists of such a structure, as shown to the arrow direction of FIG. 2 from the air pump 4 via the air supply pipe 3, air is first supplied to the gaseous-phase part 2 in the container 1 here. Supply. As air is supplied into the gas phase part 2 in this way, the pressure in the gas phase part 2 gradually increases, and as a result, the liquid level of the chemical solution is changed as shown by the two-dot chain line and the solid line in FIG. It will be pushed down.

  When the liquid level 6 of the chemical liquid 5 is pushed down, a part of the chemical liquid 5 flows into the chemical liquid supply pipe 7 as shown by the arrow direction in FIG. The chemical solution supply pipe 7 flows upward from one end side 7a of the supply pipe 7, and is supplied from the chemical solution supply pipe 7 to the outside of the container 1, specifically, to a supply destination such as a washroom.

  And in the washroom etc. which are supply destinations, a chemical | medical solution will be discharged from the other end side (not shown) of the said chemical | medical solution supply pipe 7. FIG.

  When the chemical liquid is supplied in this way, the driving force for pushing down the liquid surface 6 of the chemical liquid 5 and supplying the chemical liquid to the outside of the storage container 1 through the chemical liquid supply pipe 7 is an air pump 4 outside the storage container 1. Can be generated only by the air blown from the air supply pipe 3 into the gas phase section 2, so there is no need to provide a mechanism section such as a pump mechanism in the container 1. Does not come into contact with chemicals. As a result, there is no possibility of causing energy loss or the like in the driving force for supplying the chemical solution without causing a problem such as corrosion of the mechanism portion by the chemical solution.

  Further, the air pump 4 is configured to operate with a timer, whereby the supply amount of the chemical solution from the chemical solution supply pipe 7 can be adjusted by the operation time of the air pump 4.

  In the above-described embodiment, the case where a cleaning agent or the like is used as a chemical solution and the chemical solution supply device is installed in a washroom or the like has been described. However, the use of the chemical solution supply device is not limited to the embodiment. It is also possible to use the urine stone removing agent as an application and install the chemical supply device in a male urinal.

Such a liquid medicine supply device installed in a men's urinal contains, for example, a solid medicine in a container, and at the time of washing with water, water flows into the container to dissolve the medicine into a medicine, which is discharged into the male urinal. However, the chemical supply device of the present invention stores a liquid urine stone removing agent in the storage container 1, and as described above, the storage container 1, the air pump 4, the air supply pipe 3,
Since the liquid urine stone removing agent can be discharged from the chemical liquid supply pipe 7 to the men's urinal using the chemical liquid supply apparatus having a simple configuration only including the chemical liquid supply pipe 7, at the time of washing as described above Therefore, the urinary stone removing agent can be supplied to the male urinal even when the male urinal is not used.

  In addition, when applied to such a chemical solution supply apparatus installed in a men's urinal, if the air pump 4 is configured to operate with a timer as described above, a user is generally extremely difficult to use in a public toilet, for example. Even at nighttime when there seems to be few, the urinary stone removing agent can be supplied to the male urinal by operating the air pump 4 with a timer.

  Furthermore, in the said embodiment, although the storage container 1 was comprised by the container main body 8 and the cover body 9, the structure of the storage container 1 is not limited to this embodiment.

  In addition, it is also possible to configure the chemical liquid supply apparatus by housing the container 1, the air pump 4, the air supply pipe 3, the chemical liquid supply pipe 7, and the like as described above in a casing or the like.

  Further, in the above embodiment, since the air pump 4 is configured to operate with a timer, the above-described preferable effects are obtained. However, the configuration in which the air pump 4 is operated with a timer in this way is described in the present invention. It is not an essential condition.
