These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
Example 1:
referring to fig. 5 to 11, the present embodiment provides a check valve including: the device comprises a guide body 1, an air inlet 11 and an air outlet 12 which are arranged on the guide body 1, and a valve body which is arranged in the guide body 1 and is suitable for plugging the air inlet 11; wherein, a cavity 13 for accommodating the valve body is arranged in the guide body 1, and the air inlet 11 and the air outlet 12 are communicated with the cavity 13; the valve body is suitable for moving in the cavity 13 from the gas inlet 11 to the gas outlet 12 to conduct gas inside and outside the cavity 13. The specific shape of the guide body 1 of the present embodiment is not limited in any way, and may be a cylindrical structure, or may be other shapes, and for the shape of the cavity 13 of the guide body 1, the cavity 13 of the valve body is preferably a regular cylindrical structure in consideration of the smoothness of the movement process of the valve body in the cavity 13.
Specifically, when the valve block blocks the gas inlet 11, the valve block serves as a partition between the gas inlet 11 and the gas outlet 12, so that gas cannot enter the cavity 13 of the guide body 1 from the gas inlet 11; when the valve body leaves the air inlet 11, the cavity 13 and the air outlet 12 are in a communicated state, and air can enter the cavity 13 of the guide body 1 through the air inlet 11 and then is discharged from the air outlet 12. The specific arrangement positions of the air inlet 11 and the air outlet 12 on the guide body 1 are not absolutely limited in this embodiment, that is, in the process of moving the valve body in the cavity 13, when the valve body does not block the air inlet 11, the valve body does not block the air outlet 12, so that the air can smoothly enter the cavity 13 from the air inlet 11 and then be discharged from the air outlet 12; when the valve body forms a plug for the air inlet 11, the valve body can not form a plug for the air outlet 12, and the use requirements of the embodiment are met.
For the valve body used in the present embodiment, in an alternative embodiment, the valve body includes a flexible body 16 for blocking the air inlet 11 and an elastic body 15 connected to the flexible body 16, that is, the valve body includes a flexible body 16 and an elastic body 15 which are separated but connected, where the elastic body 15 is, for example, but not limited to, a spring. In yet another alternative embodiment, the valve body is a flexible member made of an elastic material and having an integral structure. This embodiment is not limited in any way.
Next, a valve body of a split structure will be described by way of example with reference to the accompanying drawings. The specific matching structure of the valve body and the guide body 1 with a split structure can adopt the following two conditions:
in the first case, the elastic body 15 is connected with the end surface of the flexible body 16 facing the air inlet 11, that is, the elastic body 15 is arranged between the cavity wall of the cavity 13 with the air inlet 11 and the flexible body 16; here, two elastic bodies 15 can be symmetrically arranged, the two elastic bodies 15 are symmetrically arranged to play a balanced tensile force for the flexible body 16, and the connecting ends of the two elastic bodies 15 and the cavity 13 are both positioned at the side of the air inlet 11; it is also possible to provide only one elastic body 15, and in this case, it is only necessary to locate the connection point of the elastic body 15 and the cavity 13 at the circumferential outer side of the air inlet 11. This embodiment is not limited in any way. In this case, the flexible body 16 blocks the gas inlet 11 in the normal elastic state of the elastic body 15, and when the gas outside the guide body 1 applies pressure to the flexible body 16, the guide body 1 moves from the gas inlet 11 to the gas outlet 12, so that the guide body 1 is separated from the gas inlet 11, and the elastic body 15 is in a state of being stretched and deformed. And when the pressure applied by the gas outside the guide body 1 to the flexible body 16 disappears, the guide body 1 will move from the gas outlet 12 to the gas inlet 11 again under the reset action of the elastic body 15 to realize the blocking of the gas inlet 11.
In the second case, the elastic body 15 is connected to the end face of the flexible body 16 facing away from the air inlet 11. In this case, the flexible body 16 blocks the gas inlet 11 in the normal elastic state of the elastic body 15, and when the gas outside the guide body 1 applies pressure to the flexible body 16, the guide body 1 moves from the gas inlet 11 to the gas outlet 12, so that the guide body 1 is separated from the gas inlet 11, and the elastic body 15 is in a compressed state. And when the pressure applied by the gas outside the guide body 1 to the flexible body 16 disappears, the guide body 1 will move from the gas outlet 12 to the gas inlet 11 again under the reset action of the elastic body 15 to realize the blocking of the gas inlet 11.
In addition to the above configuration, in order to further improve the sealing property between the flexible body 16 and the intake port 11 in the closed state, the present embodiment is configured such that the end surface of the intake port 11 facing the flexible body 16 is provided with a projection 18 extending along the edge of the intake port 11 toward the cavity 13 and adapted to abut against the valve body. The protrusion 18 may be an annular structure along the edge of the air inlet 11, and the annular structure may press against the flexible body 16 to slightly deform the flexible body 16, so as to effectively ensure the sealing performance between the flexible body 16 and the air inlet 11.

In the dispenser 2 of the present embodiment, in further detail, the main housing 21 is a box structure with one side open, and the panel 22 is adapted to close the open side of the main housing 21 so as to form a chamber 23 with the main housing 21 for storing liquid. The main housing 21 of the dispenser 2 is also connected to a metering pump 24, the metering pump 24 communicating with the chamber 23 and delivering the liquid in the chamber 23 to the outside of the chamber 23. A liquid inlet 221 and a liquid outlet 222 are arranged on the panel 22, and an input end of the metering pump 24 is communicated with the chamber 23, and an output end of the metering pump 24 is communicated with the liquid outlet 222.
When the dispenser 2 of the present embodiment is used in a dishwasher 3, the dispenser 2 is mounted on the door of the dishwasher 3 and, for the dispenser 2 mounted on the door, the side of the main housing 21 facing away from the panel 22 abuts the door. When the locomotive is closed, the liquid inlet 221 is positioned above the liquid outlet 222, and liquid can be conveyed from top to bottom along the pipeline under the action of gravity; and the liquid inlet 221 is provided with a sealing cover 25 adapted to seal the liquid inlet 221. It should be noted that the air inlet 11 of the one-way valve is located on the side of the main housing 21 away from the panel 22, and in one instance, referring to the drawings, the air inlet 11 is located on one side end of the guide body 1 in the width direction; namely, the side of the guide body 1 provided with the air inlet 11 is fixedly connected with the main housing 21.
In consideration of the sealing property of the mating surface of the main housing 21 and the face plate 22, the outer periphery of the mating surface of the face plate 22 and the main housing 21 is further provided with a seal ring 27.
For the case of the arrangement of the air outlet 12 of the present embodiment that dispenses the check valve practical therein, the following structure may be adopted:
the first structure is as follows: the end of the guide body 1 opposite to the air inlet 11 is a closed end; and when the panel 22 is fixed to the main housing 21, the closed end contacts the panel 22, and the contact state between the closed end and the panel 22 does not affect the assembly between the panel 22 and the main housing 21. In this case, in the case of a valve body structure of a separate structure with reference to the drawings, and the side end of the elastic body 15 and the flexible body 16 away from the air inlet 11 of the valve body are connected, one end of the elastic body 15 is connected to the flexible body 16, and the other end of the elastic body 15 is connected to the closed end of the guide body 1 opposite to the air inlet 11. In this structure, the air outlet 12 is disposed on the circumferential side wall of the closed end, and there may be only one air outlet 12 or a plurality of air outlets 12 arranged at intervals, which is not absolutely limited in this embodiment.
The second structure is as follows: the end of the guide body 1 opposite to the air inlet 11 is a closed end; and when the panel 22 is fixed to the main housing 21, a slight gap exists between the closed end and the panel 22. In this case, in the case of a valve body structure of a separate structure with reference to the drawings, and the side end of the elastic body 15 and the flexible body 16 away from the air inlet 11 of the valve body are connected, one end of the elastic body 15 is connected to the flexible body 16, and the other end of the elastic body 15 is connected to the closed end of the guide body 1 opposite to the air inlet 11. In this structure, the air outlet 12 is disposed on the circumferential side wall of the closed end, and there may be only one air outlet 12 or a plurality of air outlets 12 arranged at intervals, which is not absolutely limited in this embodiment.
A third structure: the end part of the guide body 1 opposite to the air inlet 11 is an open end; and when the panel 22 is fixed with the main casing 21, the open end contacts with the panel 22; in this case, in the case of a valve body structure of a separate structure with reference to the drawings, and the side end of the elastic body 15 of the valve body facing away from the intake port 11 is connected to the side end of the flexible body 16, one end of the elastic body 15 is connected to the flexible body 16, and the other end of the elastic body 15 is in contact with the end face of the face plate 22 facing the guide body 1. In this structure, the air outlet 12 is disposed on the circumferential side wall of the open end, and there may be only one air outlet 12 or a plurality of air outlets 12 arranged at intervals, which is not limited to this embodiment.
A fourth configuration: the end part of the guide body 1 opposite to the air inlet 11 is an open end; and when the panel 22 is fixed with the main housing 21, a micro gap is formed between the open end and the panel 22; in this case, in the case of a valve body structure of a separate structure with reference to the drawings, and the side end of the elastic body 15 of the valve body facing away from the intake port 11 is connected to the side end of the flexible body 16, one end of the elastic body 15 is connected to the flexible body 16, and the other end of the elastic body 15 is in contact with the end face of the face plate 22 facing the guide body 1. At this time, a stopper 223 adapted to be inserted into the elastic body 15 is optionally provided on the end surface of the panel 22 facing the main housing 21, so as to improve the stability of the use state of the elastic body 15. In this structure, the air outlet 12 is disposed on the circumferential side wall of the open end, and there may be only one air outlet 12 or a plurality of air outlets 12 arranged at intervals, which is not limited to this embodiment. It should be noted that the micro-gap existing between the open end of the guiding body 1 and the face plate 22 in this structure can also form a discharge path for the gas entering from the gas inlet 11 in the guiding body 1, i.e. the gas in the guiding body 1 is discharged together with the gas outlet 12.
A fifth configuration: the end part of the guide body 1 opposite to the air inlet 11 is an open end; and when the panel 22 is fixed with the main housing 21, a micro gap is formed between the open end and the panel 22; in this case, in the case of a valve body structure of a separate structure with reference to the drawings, and the side end of the elastic body 15 of the valve body facing away from the intake port 11 is connected to the side end of the flexible body 16, one end of the elastic body 15 is connected to the flexible body 16, and the other end of the elastic body 15 is in contact with the end face of the face plate 22 facing the guide body 1. At this time, a stopper 223 adapted to be inserted into the elastic body 15 is optionally provided on the end surface of the panel 22 facing the main housing 21, so as to improve the stability of the use state of the elastic body 15. In this configuration, the air outlet 12 is formed by the micro-gap existing between the open end of the guide body 1 and the face plate 22, that is, in this case, it is not necessary to additionally provide the air outlet 12 on the guide body 1.
It should be noted that, when filling the chamber 23 of the dispenser 2 and when the dispenser 2 is in operation, the highest longitudinal level K of the liquid in the chamber 23 is lower than the outlet 12 of the one-way valve, so that the liquid in the chamber 23 does not enter the guide body 1, both in the filled state and in the operating state. So set up, can make the air inlet 11 department of check valve can not have liquid agent all the time, liquid agent can not ooze from air inlet 11 during the liquid feeding promptly, and during operation, liquid agent liquid can not flow from the air inlet 11 that opens.
Referring now to the drawings in greater detail, when the door of the dishwasher 3 is opened horizontally, the XOY surface of the dispenser 2 is oriented horizontally, and the dispenser 2 can be filled; when the door of the dishwasher 3 is gradually closed from the horizontally opened state to enter the working state, the XOY plane of the dispenser 2 is gradually displaced from the horizontal orientation to the vertical orientation.
When the distributor 2 works, the one-way valve is opened timely, namely, the valve body of the one-way valve is in a blocking state with respect to the air inlet 11, at the moment, the external air of the distributor 2 can enter the guide body 1 through the air inlet 11 of the guide body 1 and then enter the chamber 23 of the distributor 2 from the air outlet 12 of the guide body 1, and at the moment, the chamber 23 of the distributor 2 is communicated with the outside, so that the air pressure inside and outside the chamber 23 of the distributor 2 can be balanced. When the distributor 2 does not work, the one-way valve is closed, namely, the valve body of the one-way valve blocks the air inlet 11, and the valve body separates the cavity 23 of the distribution cavity from the outside, so that the reliable sealing of the cavity 23 of the distribution cavity is effectively ensured.
Specifically, when the dispenser 2 is in a non-operating state, the flexible body 16 closes and seals the air inlet 11 under the action of the elastic body 15, and at this time, the chamber 23 of the dispenser 2 is in a closed and isolated state from the outside, so that the liquid agent in the chamber 23 does not leak out and volatilize. Because the air inlet 11 of the one-way valve is positioned on the main shell 21, after the distributor 2 is installed, the air inlet 11 is positioned in the door of the dishwasher 3, and the sealing state of the air inlet is not influenced by high-temperature steam or high-pressure water flow in the washing cavity of the dishwasher 3; in addition, the air inlet 11 of the one-way valve is arranged on the main shell 21 (the distributor 2 is not visible after being assembled with the machine door), so that the damage to the air inlet 11 by people can be effectively avoided. When the distributor 2 is in the working state, because the liquid agent in the chamber 23 of the distributor 2 is pumped out, the air pressure in the chamber 23 is reduced, the external air pressure can press the flexible body 16 to move towards the direction far away from the air inlet 11 and compress the elastic body 15 by a certain amount, at the moment, the air inlet 11 is opened, the external air can enter the chamber 23 of the distributor 2 from the guide body 1 through the air inlet 11, and therefore the air pressure inside and outside the chamber 23 of the distributor 2 is balanced, and the metering pump 24 can work normally. After the air pressure is balanced, the flexible body 16 is reset under the action of the elastic body 15, and the sealing state of the air inlet 11 is recovered.
