Description

A check valve for SPA pond

Technical Field

The utility model relates to a use pond control flap technical field among the small household appliances such as water heater, especially relate to a check valve for SPA pond.

Background

The use fan has all can exist the check valve that prevents into water in the SPA machine of bathing in the existing market, but the check valve surface is the plane or the sphere leads to the windage great, and more amount of wind is rebound can not be better, reduces the availability factor of the fan amount of wind.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a SPA is check valve for pond, its gap that forms between through connector and the passageway, and then can be when the fan produces the amount of wind, effectively with the both ends of wind dispersion to valve rod for the better atress of check valve is opened.

In order to achieve the above purpose, the present invention is implemented by the following technical solutions.

A one-way valve for a SPA pool comprises,

the SPA pool is at least provided with a water flow pipeline to form a water channel;

the fan is arranged close to the SPA pool, and an air channel generated by the fan is close to the water channel;

the valve body is arranged between the water channel and the air channel, and the opening direction of the valve body is arranged in the same direction as the airflow direction in the fan;

In this embodiment, during the use, in the valve rod activity, utilize the spring to carry out spacing and enclose the fender, ensure safe in utilizationly.

Example 4

In the present embodiment, description will be given with specific use.

In this embodiment, the water course in the SPA pond 100 is the L type setting with the wind channel, all is provided with the check valve on wind channel and water course, and this kind of using-way for after opening many times, the valve could be opened, and the leakproofness is better.

Referring to the drawings, the fan 200 is further provided with a filter assembly 600 for filtering outside air, specifically selecting filter cotton, and an SPA pool 100 is provided below the fan 200, and the purpose of the SPA pool is two: firstly, water in the water tank is prevented from rebounding or entering the fan under the action of force, and the fan is prevented from entering water; on the other hand, the problem that the air resistance is too large and the air quantity is consumed too much when the fan is used is avoided, and the using efficiency of the fan is reduced.

Specifically, in this embodiment, the pipeline is added at the fan inlet to form an air duct, at this moment, the air duct and the fan are provided with a check valve, and then the check valve is arranged in the direction perpendicular to the air duct, and the water channel is provided with the check valve. During specific installation, the one-way valve can be directly arranged at the position, close to the water channel, of the fan, and then a direct assembly mode is achieved.

In this embodiment, during the assembly of the check valve, an air outlet sealing element, i.e., a first sealing ring 510, may be further added below the fixing support 500 to seal the air outlet, the plug 320 and the valve rod 310 are both assembled on the fixing support 500, and a second sealing ring 322 formed by sealing silica gel is disposed at the joint of the fixing support 500 and the plug 320 to improve the sealing performance.

Further, in this embodiment, the plug 320 includes a conical head and a spherical structure located at the bottom of the conical head, the spherical structure is used for plugging, and the conical head is used for guiding the airflow.

In this embodiment, when the fan during operation, the end cap department of check valve is blown to the wind that produces, and when contact seal structure, if the wind is less this moment, and then rock slope silica gel spare a little, but it still can form linear connection with tee bend pipeline (or water course or wind channel) inner wall and reach sealed effect. When the wind power is smaller than the elastic force, the part is still in a sealing state, when the wind power is larger than the elastic force of the spring, the wind blows to the silica gel conical surface, the wind is guided to a linear sealing (namely a sealing structure) position better through the wind breaking conical surface, and meanwhile, the wind power loss is reduced, so that the whole plug drives the valve rod to retreat, and the valve is opened; when the one-way valve is controlled, the one-way valve is opened when wind force is larger than the elastic force of the spring and the water pressure in the water pool, otherwise, the one-way valve is in a sealing state.

The above list of details is only for the practical implementation of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention should be included in the scope of the present invention.
