Upper drainage system for footbath chair
Technical field
The present invention relates to a kind of upper drainage system more particularly to a kind of upper drainage systems for footbath chair.
Background technology
In the prior art, footbath chair drainage pattern is divided into draining and lower draining, and upper draining is logical when being exactly footbath chair draining
It crosses draining pump lifting waste water to be then exhausted from, lower draining is discharged using natural pressure.At present draining pump used by China be mostly from
Heart pump, it is well known that the centrifugal force that centrifugal pump generates when driving liquid at high speed to rotate by high-speed rotating impeller makes water outlet produce
It gives birth to pressure and water is discharged, while in water inlet in water suction pump.But if having in starting mode of pump advance water pipe and draining pump
Air, impeller are the air rotation driven in pump, because of the severe very little of air, the centrifugal force of generation is too small, cannot be pump
Air in interior and pipeline is all discharged, i.e., vacuum cannot be generated in pump, thus water just can not be inhaled.And what the country used washes one's hair
Drainage system substantially lacks exhaust apparatus on sufficient chair, it is sometimes desirable to close valve and turn back on up to as many as three or four times, cause to make
The inconvenience used.Especially with the footbath chair of foot-washing basin made of the fragile materials such as glass, due on fragile material
Processing hole easy tos produce slight crack, and the installation for causing exhaust apparatus is inconvenient.
Invention content
Present invention seek to address that above-mentioned mentioned technical problem, provides a kind of upper drainage system for footbath chair, energy
It is automatically drained out air in water inlet pipe and draining pump, suitable for using the foot care of the foot-washing basin made of the fragile materials such as glass
Chair.
The present invention is realized by following technical solution:
For the upper drainage system of footbath chair, including draining pump, exhaust pipe, water inlet in the chassis interior of footbath chair are set
The water inlet of pipe, outlet pipe, the draining pump is connected by the discharge outlet of the bottom of water inlet pipe and foot-washing basin;The draining pump
Water outlet is connect by outlet pipe with external pipeline;The inlet end of the exhaust pipe and the water inlet of draining pump connect, exhaust
The outlet side of pipe is arranged at the top of foot-washing basin.
Preferably, the water check valve for preventing flow returning drainage from pumping is additionally provided between the draining pump and outlet pipe.
Preferably, the outlet side of the exhaust pipe is connected with single tube elbow, the single tube elbow include the first cuboid section,
First bending section and the first linkage section, the first cuboid section both ends are separately connected the first bending section and the first linkage section, the
One cuboid section is arranged at the top of the pedestal of footbath chair, and the first linkage section is threadedly coupled with exhaust pipe.
Preferably, the outlet side of the exhaust pipe connects two-tube elbow, and the two-tube elbow includes the second cuboid section, the
The both ends of two bending sections and two the second linkage sections, the second cuboid section are separately connected the second bending section and two second companies
Section is connect, the second cuboid section is arranged at the top of the pedestal of footbath chair;Independent through-hole there are two being set on second bending section
Two the second linkage sections are extended through, exhaust pipe is threadedly coupled with one of them second linkage section.
Preferably, the discharge outlet of the water inlet pipe and foot-washing basin is connected by lower water elbow.
Preferably, the pipeline opening of the water inlet pipe is equipped with filter.
Preferably, the exhaust pipe is metal bellows.
Preferably, the exhaust pipe is plastic film capicitor.
Advantageous effect is:Compared with prior art, a kind of upper drainage system for footbath chair, suitable for using by glass
The footbath chair of foot-washing basin made of the fragile materials such as glass, can be automatically drained out air in water inlet pipe and draining pump, and avoiding the occurrence of cannot
The failure of draining, it is simple in structure, easy to use.
Description of the drawings
The specific implementation mode of the present invention is described in further detail below in conjunction with attached drawing, wherein:
Fig. 1 is the structural schematic diagram of the embodiment of the present invention one;
Fig. 2 is the structural schematic diagram of the embodiment of the present invention two;
Fig. 3 is the connection schematic diagram of the embodiment of the present invention one.
Specific implementation mode
Embodiment one
As shown in figures 1 and 3, it is used for the upper drainage system of footbath chair, including is arranged inside the pedestal 10 of footbath chair
Draining pump 1, exhaust pipe 2, water inlet pipe 3, outlet pipe 4, the bottom that the water inlet of the draining pump 1 passes through water inlet pipe 3 and foot-washing basin 11
The discharge outlet in portion connects;Water inlet pipe 3 can be connect with the discharge outlet of the bottom of foot-washing basin 11 by lower water elbow 5.The draining
The water outlet of pump 1 is connect by outlet pipe 4 with external pipeline;The inlet end of the exhaust pipe 2 connects with the water inlet of draining pump 1
It connects, there is water to go out from 2 overflow of exhaust pipe when being vented in order to prevent, the outlet side of exhaust pipe 2 is arranged at the top of foot-washing basin 11.For
Enhancing exhaust effect, the installation site of exhaust pipe 2 should be close proximity to draining pump 1.
Under normal circumstances, after draining, remaining water can countercurrently return in draining pump 1 in outlet pipe 4, in order to prevent should
The generation of phenomenon is additionally provided with the water check valve 7 for preventing flow returning drainage pump 1 between draining pump 1 and outlet pipe 4.
The outlet side of exhaust pipe 2 is connected with single tube elbow 8, and the single tube elbow 8 includes the first cuboid section, the first bending
Section and the first linkage section, the first cuboid section both ends are separately connected the first bending section and the first linkage section, the first cuboid
Section is arranged at the top of the pedestal 10 of footbath chair, and the first linkage section is threadedly coupled with exhaust pipe 2, and the first bending section is towards foot-washing basin
11。
In order to protect draining pump 1, prevent sundries from entering draining pump 1, the pipeline opening of water inlet pipe 3 is equipped with filter(In figure not
It shows).
Exhaust pipe 2 is metal bellows or plastic film capicitor.
Embodiment two
As shown in Fig. 2, the outlet side of exhaust pipe 2 connects two-tube elbow 9, the two-tube elbow 9 include the second cuboid section,
Second bending section and two the second linkage sections, the both ends of the second cuboid section are separately connected the second bending section and two second
Linkage section, the second cuboid section are arranged at the top of the pedestal 10 of footbath chair;It is independent there are two being set on second bending section
Through-hole extends through two the second linkage sections, and exhaust pipe 2 is threadedly coupled with one of them second linkage section.Another second connection
Section is connected to the water source to supply water for footbath chair.By using above-mentioned two-tube elbow 9, it is provided simultaneously with exhaust and water supply function, is subtracted
A tap is lacked, structure is simpler, and installation is also more convenient.Place reference implementation example one is not specified in the present embodiment.
The above embodiments are merely illustrative of the technical solutions of the present invention and is not intended to limit it, all without departing from the present invention
Any modification of spirit and scope or equivalent replacement, shall fall within the scope of the technical solution of the present invention.
