Description

Multifunctional check valve structure

Technical Field

The utility model relates to an electrical appliance structure, in particular to a multifunctional check valve structure.

Background

With the improvement of living standard, the requirements of people on indoor environment are higher and higher, and especially the indoor air quality has attracted important attention, so that the indoor air interchanger becomes a necessary choice of indoor electric appliances, and especially places where the air quality of two places, namely a kitchen and a bathroom, is easy to cause problems.

At present, a kitchen or a bathroom often has only one outdoor exhaust hole, but when two outdoor exhaust electric appliances need to be installed, the hole needs to be increased, and the hole needs to be increased again, so that the switching structure which can use one hole and can be communicated with the two electric appliances is an urgent product in the market.

Disclosure of Invention

In order to solve the problems, the utility model provides the following scheme:

the multifunctional check valve structure comprises a first valve cavity and a second valve cavity, wherein the first valve cavity is of a three-way structure and comprises a first outlet, a first inlet and a first communication port, the first outlet is internally provided with the first check valve, the first valve cavity is internally provided with a switching baffle plate, the switching baffle plate is driven by a switching motor to rotate, and the switching baffle plate can block the first communication port or the first inlet; the second valve cavity comprises a second outlet and a second communication port, a second non-return valve is arranged in the second outlet, and the second communication port and the first communication port are buckled with each other to enable the first valve cavity to be communicated with the second valve cavity.

Further, the first check valve and the second check valve are identical in structure and comprise valve plates, a valve rod penetrates through the middle of each valve plate, the valve rod is connected with the first outlet or the second outlet, and the end head of the valve rod is connected with a switch motor.

Further, a valve sealing strip is sleeved outside the valve plate.

Further, a sealing ring is arranged at the buckling position of the first communication port and the second communication port.

The beneficial effects of the utility model are as follows:

1. two ventilation appliances can be connected at the same time, so that the occupied space or extra holes for installing pipelines of the appliances are reduced;

2. the switching of the communication state of the check valve is realized by rotating the switching partition plate to switch different states.

Detailed Description

The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.

Example 1: as shown in figures 1-4 of the drawings,

the multifunctional check valve structure comprises a first valve cavity 1 and a second valve cavity 7, wherein the first valve cavity 1 is of a three-way structure and comprises a first outlet 2, a first inlet 3 and a first communication port 4, the first outlet 2 is internally provided with a first check valve, the first valve cavity is internally provided with a switching baffle 5, the switching baffle 5 is driven to rotate by a switching motor 6, and the switching baffle 5 can seal the first communication port 4 or the first inlet 3; the second valve cavity 7 comprises a second outlet 8 and a second communication port 9, a second non-return valve is arranged in the second outlet 8, and the second communication port 9 and the first communication port 4 are buckled with each other to enable the first valve cavity 1 to be communicated with the second valve cavity 7.

Further, the first check valve and the second check valve have the same structure and comprise valve plates 10, a valve rod 11 penetrates through the middle of each valve plate 10, the valve rod 11 is connected with the first outlet 2 or the second outlet 8, and the end of each valve rod 11 is connected with a switch motor 13.

Further, a valve sealing strip 12 is sleeved outside the valve plate 10.

Further, a sealing ring 14 is arranged at the buckling position of the first communication port 4 and the second communication port 9.

When in use, the device has three different communication states: 1. the switching partition plate 5 rotates to a vertical state, so that the first communication hole 4 is communicated with the first inlet 3, the first outlet 2 is plugged, at the moment, an electric appliance communicated with the second valve cavity 7 is started, and the electric appliance can be communicated to the first inlet 3 through the second valve cavity 7; 2. the switching partition plate 5 rotates to a horizontal state, so that the first communication port 4 and the second communication port 9 are closed, the first inlet 3 and the first outlet 8 are communicated, at the moment, an electric appliance communicated with the first valve cavity 1 is started, and the electric appliance can be communicated with the first inlet 3 through the first valve cavity 1; 3. the lower end of the switching baffle plate 5 rotates to the middle position of the first inlet 3, at the moment, both the electric appliance communicated with the first valve cavity 1 and the electric appliance communicated with the second valve cavity 7 can be started, and are respectively communicated with the first inlet 3 through the second valve cavity 7 and the first inlet 3 through the first valve cavity 1.

According to the utility model, two ventilation appliances can be connected at the same time, so that the occupied space or extra holes for installing pipelines of the appliances are reduced; the switching of the communication state of the non-return valve is realized by rotating the switching partition plate 5 to switch different states.
