Example 1
A detergent dispenser, which comprises a containing cavity 1 for storing a detergent 8, a liquid adding component 2 for adding the detergent 8 into the containing cavity 1 and a throwing component 3 for throwing the detergent 8 in the containing cavity 1 to the outside; a one-way valve 4 which is conducted to the outside in a one-way is arranged at the outlet of the liquid outlet pipeline 302 in the throwing component 3; the cavity 1 is provided with a gas guide cavity 101 for discharging the gas in the cavity 1. The outside refers to a washing tub, such as a washing tub of a washing machine or a washing tub of a dishwasher, etc. As shown in fig. 1, the accommodating cavity 1 is distributed on the whole plate surface of the detergent dispenser, the liquid adding component 2 is positioned at the upper right of the accommodating cavity 1, and the throwing component 3 is positioned at the middle part and the lower right of the accommodating cavity 1.
The liquid adding component 2 generally comprises a liquid adding opening, a liquid adding cover and a sealing ring for sealing the liquid adding opening and the liquid adding cover, and the throwing component 3 generally comprises a conveying pump 303, a liquid inlet pipeline 301 connected with the inlet end of the conveying pump 303, a liquid outlet pipeline 302 connected with the outlet end of the conveying pump 303 and a throwing part 304 connected with the liquid outlet pipeline 302, wherein the other end of the liquid inlet pipeline 301 is connected with the containing cavity 1, and after the conveying pump 303 is started, the detergent 8 in the containing cavity 1 is sucked in from the liquid inlet pipeline 301 and discharged through the liquid outlet pipeline 302, so that the throwing of the detergent 8 is completed. For ease of observation, the discharge portion 304 of the discharge assembly and the one-way valve 4 are separated from the discharge pipe 302 in the exploded view shown in fig. 1.
The one-way valve 4 is opened when the liquid outlet pipeline 302 is out of liquid (namely, when the delivery pump 303 works), and the detergent 8 can be pumped out; the check valve 4 is closed when the liquid outlet pipe 302 stops discharging liquid (that is, when the delivery pump 303 is closed), at this time, the liquid outlet of the liquid outlet pipe 302 is sealed, and the liquid outlet pipe 302 is isolated from the outside, so that the liquid which is not pumped in the liquid outlet pipe 302 can be prevented from drying.
The air guide cavity 101 is beneficial to discharging the air in the accommodating cavity 1 instead of discharging the air only by virtue of the extrusion force of the detergent 8, and the discharged air in the accommodating cavity 1 is beneficial to rapidly diffusing the detergent 8 in the accommodating cavity 1, so that the accumulation of the detergent 8 at a liquid adding port is avoided.
The structure of the check valve 4 in this embodiment is: as shown in fig. 3, the valve body support device comprises a valve body support member 401, a pressure spring 402 and a sealing member 403, wherein the valve body support member 401 is fixedly arranged, and the pressure spring 402 is sleeved on the valve body support member 401; when the one-way valve 4 is in a closed state, the pressure spring 402 can push the sealing element 403, so that the sealing element 403 seals the outlet of the liquid outlet pipeline 302; when the non-return valve 4 is in the open state, the compression spring 402 is able to contract under the pressure of the liquid in the liquid outlet channel 302, so that the sealing member 403 leaves the outlet of the liquid outlet channel 302. The outer peripheral surface on the valve body support piece 401 is a cylindrical surface and is used for supporting a pressure spring 402, the pressure spring 402 is sleeved on the outer periphery of the valve body support piece 401, one end of the pressure spring 402 is abutted against the end face of the valve body support piece 401, the other end of the pressure spring 402 is abutted against the end face of the sealing piece 403, and when the pressure spring 402 stretches and contracts due to the fact that the valve body support piece 401 is fixed, the sealing piece 403 can be close to or far away from the liquid outlet pipeline 302.
The principle of the one-way valve 4 is as follows: when the delivery pump 303 pumps out the liquid in the cavity 1, the pumped liquid has a strong pressure, and the pressure satisfies the compression of the compression spring 402, and the one-way valve 4 is in an open state at this time, so that the delivery can be performed. As shown in fig. 3, in the open state, the arrows indicate the path of the liquid in the open state of the check valve 4, and the liquid presses the seal 403 to the right while flowing out. When the delivery pump 303 does not work, no pressure is used for compressing the sealing element 403 at this time, under the action of the elastic force of the compression spring 402, the sealing element 403 is attached to the outlet of the liquid outlet pipe 302, the liquid outlet is sealed, the communication with the outside air is isolated, and the liquid in the liquid outlet pipe 302 which is not pumped out is prevented from being dried.
The containing cavity 1 is provided with a liquid storage cavity 102 communicated with the air guide cavity 101, when the detergent dispenser is in a liquid adding state, the highest surface of the air guide cavity 101 is higher than the highest surface of the liquid storage cavity 102, an air hole 6 is formed in the highest surface of the air guide cavity 101, a waterproof and breathable film 7 is arranged at the air hole 6, and when the containing cavity 1 is full of liquid, the air guide cavity 101 cannot be filled with the liquid and plays a role in air guide and exhaust, as shown in fig. 5. The lowest surface of the air guide cavity 101 is lower than the highest surface of the liquid storage cavity 102, at this time, the air guide cavity 101 is directly communicated with the liquid storage cavity 102, and the liquid in the liquid storage cavity 102 can spread into the air guide cavity 101. Preferably, the lowest surface of the air guide cavity 101 is flush with the lowest surface of the liquid storage cavity 102 when the detergent dispenser is in a liquid-filled state. The air guide cavity 101 is based on the following principle: when the liquid filling opening is used for filling liquid, the viscosity of the used detergent 8 is high, the flow speed is low, the detergent is collected around the liquid filling opening, the liquid can reach the highest surface of the liquid storage cavity 102, and the gas in the containing cavity 1 is discharged to the outside through the gas guide cavity 101.
