Description

  The present invention relates to a shower head device, and more particularly to a shower head device provided with a simple mechanism for mixing soap, bathing agent, or fragrance into shower water.

  A conventional shower head device includes a water discharge portion that discharges water, and is used for bathing. However, the discharged water is simply water or warm water. The water itself has no effect. In view of this, a shower head device having a mechanism for mixing soap, bathing agent, or fragrance into the water discharged from the shower head has been developed.

  The shower head developed by the present inventor and disclosed in US Pat. No. 9,322,152, filed in the United States of America, has a cylindrical shape and is provided with a front lid and a rear lid on the front and rear, respectively. A drum for storing liquid soap is provided in the main body so as to be rotatable, and a liquid outlet is formed in the drum, and a plurality of blades are provided on the outer peripheral surface of the drum to generate a swirling flow in the shower head. Then, the drum is rotated, and the liquid soap, bathing agent, fragrance or the like stored in the drum is discharged from the liquid outlet by centrifugal force and mixed into the shower water.

  In addition, the shower head is provided with a support plate for rotatably supporting the drum in order to switch between shower water mixed with soap and normal shower water not mixed, and is screwed on the outer peripheral surface. A switching knob provided on the front lid of the shower body on the side from which shower water is discharged, and a switching mechanism in which one end of the shaft passes through the front lid and is connected to the support plate.

  The switching mechanism described above transmits the force to rotate the knob to the shaft by rotating the knob, and moves the drum along the axial direction in the shower head body. Moves from the position of the water entry hole at the upper end of the shower water flow path formed in the grip portion connected to the shower head body to the rear lid side, the water that has entered the shower head body from the water entry hole is It discharges from a plurality of discharge holes formed in the front lid without being in contact with the drum and being in contact with the drum. When the drum is positioned on the water entrance hole, it is rotated by the propulsion of water flow, and the liquid soap, bathing agent, fragrance, etc. stored in the drum flows out from the liquid outlet by centrifugal force and mixes into the shower water. The liquid is discharged from a plurality of discharge holes formed in the front lid.

  Further, the shower head includes an aspirator structure at a lower end portion of the grip portion. That is, the grip portion forms a shower water flow path from the bottom end to the top end in the interior, and the shower water flow passage gradually reduces the inner diameter upward at the bottom end portion to form a tapered portion, The upper end of the tapered portion becomes a nozzle, and after passing through the nozzle, the inner diameter of the shower water flow path becomes wider and communicates with the internal space of the shower head body at the upper end of the grip portion. Further, an intake hole is drilled at an appropriate position near the nozzle of the grip portion.

The shower head described above. Liquid soap and the like can be efficiently mixed into the shower water, and since an aspirator structure is provided, a synergistic effect with a structure in which liquid soap and the like are mixed into the shower water can be obtained. That is,
Fine water bubbles can be included in the shower water, and there are advantages such as saving water or buffering the impact force of the shower water against the skin. It is obtained and the cleaning effect by shower can be enhanced.

  However, the showerhead described above has several drawbacks in implementation. That is, the shower head body includes a shaft having one end connected to the support plate, a knob at the other end of the shaft, the front lid through which the shaft passes, and a support plate that rotatably supports the drum. And a drum for storing liquid soap and the like, and the rear cover for rotatably supporting the drum together with the support plate. In other words, the number of members is large, the manufacturing process is increased and labor is required, and the manufacturing cost is relatively increased.

  The drum, which is a container for storing liquid soap, has a plurality of blades on the outer peripheral surface. It is difficult at present to integrally form such a structure. For this reason, the blades must be connected to the outer peripheral surface of the drum. In this case, methods such as welding and adhesion are conceivable, but in any case, considerable labor and time are wasted in the processing step of the drum. In addition, the area where the blades come into contact with the drum is very small, and sufficient connection strength cannot be obtained. Since the blades are intended to rotate the drum in response to swirling flow of shower water, a low connection strength will easily break the blade, which will cause the drum to fully The centrifugal force is generated by rotation, and the stored liquid soap or the like cannot flow out.

United States Patent No. 9,322,152

  The present invention provides a shower head device that has a mechanism for mixing liquid soap, bathing agent, or fragrance, has a simple structure, has sufficient structural strength, and can be easily manufactured. Let it be an issue.

  Therefore, as a result of intensive research in view of the drawbacks found in the conventional shower head device, the present inventor has formed a substantially tapered shape that has a cylindrical shape and the inner space gradually decreases in diameter toward the rear lid. And the bottom surface is an approximately central position in the axial direction of the shower head main body, and water enters the position biased to one side along a line perpendicular to the axial direction of the shower head main body. A shower head main body having a hole formed therein, a flow path through which shower water passes, and a grip portion provided on a bottom surface of the shower head main body, a front lid provided on each of the front and rear ends of the shower head main body, A rear cover, a plate body, and a shielding plate provided with a side surface inclined at the same angle as the inclination angle of the inner wall of the shower head body, and rotatable and slidable in the shower head body; Threaded on the surface An operation knob having a shaft, and provided with a columnar shaft support portion threaded on the inner wall and formed with a shaft support hole penetrating the front cover, and having one end of the shaft The problem is solved by the shower head device that passes through the shaft support hole and is connected to the shielding plate, and the side surface of the shielding plate is in contact with the inner wall of the shower head body at a position near the rear lid from the position of the entry hole. We focused on what we can do and completed the present invention based on this knowledge.

  This device will be described below. The shower head device according to claim 1 has a cylindrical shape, and an inner space has a substantially tapered shape with an inner diameter gradually decreasing toward the rear lid, and a bottom surface in the axial direction of the shower head main body is formed.

The side surface of the shielding plate contacts the inner wall of the shower head body at a position closer to the rear lid from the position of the entry hole.

  According to the structure described above, when the operation knob is rotated to one side, the shielding plate moves toward the rear end from the position of the entry hole of the shower head body, and the side surface abuts against the inner wall of the shower head body. . Therefore, the internal space of the shower head body is divided into a space between the shielding plate and the front lid and a space between the shielding plate and the rear lid. In this state, the rear lid is removed and liquid soap or the like is directly filled in the shafu head, and when a faucet such as a hot water supply device is opened, water flows into the shower in the shower head through the grip portion, and It becomes a swirling water flow and is injected from an injection hole formed in the front lid. However, the liquid soap or the like filled in the shower head main body bisects the internal space of the shower head main body due to the shielding effect of the shielding plate, and does not enter the shower water.

  Next, when the operation knob is rotated in the other direction, the shielding plate moves in the direction of the front lid, the bisected space is communicated, and the filled liquid soap is mixed into the shower water. That is, it is possible to achieve the purpose of mixing liquid soap or the like into shower water and switching between normal shower water and shower water mixed with liquid soap or the like with a simple structure.

  The aspirator device for a shower head according to claim 2 forms an injection hole having a tapered shape at the center point of the rear lid in claim 1 with the inner wall inclined and gradually shrinking toward the shower head body side. In addition, a hollow columnar protrusion formed by a wall surface surrounding the injection hole is provided on the surface on the shower head main body side, and one end of the columnar protrusion connected to the rear lid is an open end and is externally connected through the injection hole. A spherical body that has a closed end at the other end, a plurality of holes formed in the wall surface, abuts against the elastic body and the elastic body, and closes the injection hole by the urging force of the elastic body And in-house.

  According to such a configuration, the operation for filling the shower head body with liquid soap or the like can be simplified. That is, it is hard and has a taper shape that matches the shape of the injection hole of the rear lid, and has an injection end having a hole at the tip, and a liquid or paste bath soap, fragrance, bathing agent, etc. A separate injector is formed by a storage portion that is a tube containing a container, the injection end of the injector is inserted into the injection hole of the rear lid, and the storage portion is pressed to remove the contents in the storage portion. It can be injected into the showerhead body.

  The shower head device according to the present invention has a small number of members, has few joints or adhesion points, and has a simple structure, so that sufficient strength is obtained in the structure, and bath soap and the like are mixed into the shower water with a simple operation. In addition to making it possible to efficiently bathe in the shower, it is possible to switch between normal shower water and shower water mixed with liquid soap by a simple operation. That is, it is possible to obtain a long service life as a product and convenience in use, and further, an effect that manufacturing is easy and manufacturing cost can be reduced.

  In addition, a structure is provided in the shower head for mixing bath soap and the like in the shower water, and switching between normal shower water and shower water mixed in with liquid soap, and the switching operation is performed on the front lid. Since it is performed by the provided operation knob, only a flow path through which shower water passes is formed in the grip portion. According to such a structure, it is possible to further utilize the grip portion and add other functions. For example, a stop-type water stop device that stops water on the shower head side, or something that affects the water quality of shower water. It is also possible to provide a cartridge or the like in which the components are installed in the grip portion, and an aspirator structure is provided in the grip portion as in the shower head disclosed in the aforementioned US Pat. No. 9,322,152. May be provided.
