detailed description

The technical solutions of the present disclosure will be described below with reference to the accompanying drawings and the following embodiments.

Example 1

As shown in FIG. 1 , the present embodiment protects a water inlet hose of a washing machine. The water inlet hose includes a tube body 101 and a blocking device 100 disposed on the tube body 101. The blocking device 100 includes a blocking piece 102 and a stopper 103. The stopper 103 is fixed on the pipe body 101, and the blocking piece 103 is rotatably connected with the blocking piece 102, when the blocking piece When the 102 is resisted on the stopper 103, the blocking device 100 closes the outlet end of the pipe body 101. The position of the blocking device 100 may be the water outlet end of the water inlet hose or the inside of the water inlet hose.

The blocking device 100 in the water inlet hose of the washing machine comprises a blocking piece 102 and a stopper 103. The stopper 103 is fixed on the inner wall of the pipe body 101, and the blocking piece 103 is rotatably connected with the blocking piece 102. When the foam is washed, the foam will be foamed. The baffle is forced to act such that the baffle abuts against the stop 103 and the blocking device 100 is in sealing engagement with the tubular body 101 to prevent foam from flowing out of the washing machine along the inlet hose.

The flap 102 is a rubber member, and the stopper 103 is a plastic member having a certain strength to block and fix the shutter 102. Optionally, the stopper 103 and the blocking piece 102 are connected by a snap structure, and the blocking piece 102 is rotatable relative to the blocking block 103.

As shown in FIGS. 2 and 3, the flap 102 includes a flap body 104 and a first connecting portion 105, the first connecting portion 105 is disposed on one side of the flap body 104, and the stopper 103 includes a stopper body 107. And the second connecting portion 108, the buckle structure includes a first connecting portion 105 on the blocking piece 102 and a second connecting portion 108 on the blocking block 103. The first connecting portion 105 is provided with a card slot 106, and the second connection The portion 108 is a block that mates with the card slot 106. In this embodiment, the first connecting portion 105 is a block-like structure disposed radially along the shutter body 104, and the block-shaped structure is provided with an annular card slot 106 perpendicular to the longitudinal direction of the first connecting portion 105, and the second connecting portion 108 includes two symmetrical cards, the first ends of the two blocks are fixed on the block body 107, the second end is a free end, the free ends of the two blocks are close to each other, and the two blocks are simultaneously The annular card slot 106 is mated, and the two blocks clamp the first connecting portion 105 to achieve the connection between the stopper 103 and the blocking piece 102. Since the flap 102 is a rubber member, it has good elasticity. When the water enters, the pawl 102 is opened due to the momentum of the water, and the flap body 104 and the first connecting portion 105 are bent at a certain angle to realize water inflow.

As shown in FIGS. 2 and 3, the stopper body 107 includes a fixing portion 109 and an abutting portion 110. The fixing portion 109 is connected to the inner wall of the pipe body 101, and the abutting portion 110 is coupled to the fixing portion 109 and is directed to the axis of the pipe body 101. The extending portion 109 and the abutting portion 110 in this embodiment are integrally formed. The block body 107 is a closed annular plastic member. The inner wall of the pipe body 101 is provided with an annular groove 111. The fixing portion 109 is provided with an annular protrusion 112. The annular protrusion 112 and the annular groove 111 cooperate with each other. It is possible to ensure that the stopper 103 is firmly fixed to the pipe body 101. The abutting portion 110 is perpendicular to the inner wall of the tube body 101 at the corresponding position. The abutting portion 110 is provided with a side plate 113 facing the flap body 104. The side plate 113 is disposed around the flap body 104 and is opposite to the flap body 104. The interference fit ensures that the blocking device 100 can achieve a sealing fit with the inner tube when the flap 102 abuts against the stop 103. The interference fit between the side plate 113 and the flap body 104 enables the flap body 104 to be opened when there is more water flowing in the inlet hose, so that the water inlet hose can be transported or shaken when the drum washing machine is shipped from the factory. The water stored in the water can be stored in the water inlet hose under the blocking of the blocking piece 102, so as to prevent the water from flowing into the outer tube, so that the water does not deteriorate in the outer tube under high temperature conditions.

In the embodiment, the flap body 104 is a flat plate structure.

Example 2

As shown in FIG. 4-6, the water inlet hose of the washing machine protected by the embodiment is different from that of the first embodiment in that the first connecting portion 205 is provided with a card hole 206, and the second connecting portion 208 is provided with a card. The bumps 214 that the holes 206 fit. Optionally, the first connecting portion 205 is a sheet-like structure fixed on the sidewall of the blocking piece 202. The first connecting portion 205 is parallel to the side wall of the blocking piece 202, and the second connecting portion 208 is included on the block body 207. The slot body 213 is configured to receive the first connecting portion 205. The slot body 213 is provided with a protrusion 214. The protrusion 214 extends into the hole 206, and the bump 214 and the card hole 206 are interference-fitted. The secure connection between the stopper 203 and the blocking piece 202 can be ensured. When water is injected into the drum washing machine through the water inlet hose, since the blocking piece 202 is a rubber member having better elasticity, the blocking piece 202 is under the impact of water. When the stopper 203 is disengaged, the flap body 204 and the first connecting portion 205 are bent to realize water inflow.

As shown in FIG. 5, the abutting portion 210 in this embodiment is an inclined plate connected to the fixing portion 209, and the free end of the abutting portion 210 is inclined toward an end away from the blocking body 204, and the blocking body 204 and the abutting portion are 210 Interference fit. Due to the inclination of the abutting portion 210, when the flap body 204 is engaged with the abutting portion 210, the reaction force of the abutting portion 210 is received, so that the fit between the flap body 204 and the abutting portion 210 is more tight. When water is introduced, a large flow of water is required to open the flap 202, and the water in the inlet hose cannot open the flap 202 to prevent the water in the inlet hose from entering the outer cylinder when shaking.

The block body 207 is a closed annular plastic member. The inner wall of the tubular body 201 is provided with an annular groove 211. The fixing portion 209 is provided with an annular protrusion 212. The annular protrusion 212 and the annular groove 211 cooperate with each other. It is possible to ensure that the stopper 203 is firmly fixed to the tubular body 201.

In the embodiment, the flap body 204 is a plate provided with reinforcing ribs on the surface, which can strengthen the strength of the flap body 204.

In the embodiment, a drum washing machine is further protected, comprising a dispenser and an outer cylinder, and the water inlet hose of the embodiment 1 or the embodiment 2 is installed between the distributor and the outer cylinder, and the water inlet in the embodiment 1 is used. In the case of the hose, the flap 102 is located on the side of the stopper 103 away from the dispenser. When the water inlet hose of Embodiment 2 is employed, the flap 202 is located on the side of the stopper 203 away from the dispenser.
