Referring to fig. 1 to 8, an embodiment of the present invention provides a household appliance 20, which includes a conveying component 11, a first control device 15 and a feeding component 14. The transport member 11 is formed with a fluid passage 119. The first control device 15 is used to cause the fluid passage 119 to convey fluid. The feeding component 14 is used for receiving and throwing in materials.

The utility model discloses embodiment's domestic appliance 20, first controlling means 15 can control conveying element 11 and carry fluid (for example water), and pay-off component 14 can accept and put in the material (for example rice), so, realizes that domestic appliance 20 automatic control advances rice and processes such as intaking, so makes domestic appliance 20 more intelligent and multi-functional, has promoted domestic appliance 20's practicality.

In the present embodiment, the first control device 15 is connected to the conveying member 11. This facilitates the first control device 15 to cause the fluid passage 119 to convey fluid.

The household appliance 20 includes, but is not limited to, an electric cooker, an electric pressure cooker, a coffee maker, a soymilk maker, a cooking machine, and other electric devices, and the specific type of the household appliance 20 is not limited herein. In the illustrated embodiment, the household appliance 20 is an electric cooker, the conveying component 11 can supply water to the electric cooker, and the feeding component 14 can supply rice to the electric cooker, so that the electric cooker can realize the function of automatically cooking rice.

In some embodiments, the household appliance 20 includes a second control device 16, the second control device 16 is connected to the feeding component 14, and the second control device 16 is used for delivering the material to the feeding component 14.

In this manner, material addition to the feeding component 14 is facilitated.

Referring further to fig. 1 to 8, in some embodiments, the delivery unit 11 is formed with a first port 111 and a second port 112, the fluid passage 119 communicates the first port 111 and the second port 112, the household appliance 20 includes at least one first connection pipe 201 connected to the first port 111, the first control device 15 is configured to deliver fluid to the fluid passage 119 through the at least one first connection pipe 201 and out through the second port 112, and to draw fluid into the fluid passage 119 through the at least one first connection pipe 201 and into the fluid passage 119 through the second port 112.

In this manner, fluid flow into or out of the fluid passage 119 is facilitated.

Further, the first connection pipe 201 can be used for conveying fluid, and the first control device 15 can control the fluid to flow in the fluid channel 119, wherein the conveying can refer to forward conveying or directional conveying, and can be set according to different situations.

Wherein, first connecting pipe 201 can be the hose, and the setting of hose makes first connecting pipe 201 can the bending setting, under such condition, is favorable to reducing the area occupied of first connecting pipe 201 to can reduce domestic appliance 20's volume, be favorable to domestic appliance 20's miniaturized design. Of course, the first connection pipe 201 may not be just a hose, and a specific type of the first connection pipe 201 may be provided according to different situations. The specific type of the first connection pipe 201 is not limited herein.

Referring to fig. 1, 2 and 8, in an example, the number of the first connection pipes 201 is one, and at this time, the first control device 15 can implement the input and extraction functions through the first connection pipes 201, so that the number of the first connection pipes 201 can be reduced, the internal space of the household appliance 20 can be increased, and the household appliance 20 can be miniaturized.

Referring to fig. 1, 2 and 9, in another example, the number of the first connection pipes 201 is two, and the first control device 15 is used for pumping the fluid from the second port 112 into the fluid channel 119 through the first connection pipe 201; and for inputting liquid or gas to the first port 111 through the second first connection pipe 201.

The arrangement is such that the first control device 15 can control the first connection pipe 201 to input liquid or gas to the first port 111 while controlling the first connection pipe 201 to extract liquid from the second port 112 into the fluid channel 119, so as to improve the working efficiency of the household appliance 20.

In the above example, in the case where the number of the first ports 111 is two, the two first connection pipes 201 can be connected to the different first ports 111, respectively, and in this case, the two first connection pipes 201 can be operated simultaneously. That is, at this time, the first connection tube 201 draws the fluid of the second port 112 into the fluid passage 119. The second first connection pipe 201 inputs liquid or gas to the first port 111. When the number of the first ports 111 is one, since both the first connection pipes 201 are connected to the first ports 111, the two first connection pipes 201 cannot be operated at the same time.

Further, in the above example, the two first connection pipes 201 are used for different delivery (the first connection pipe 201 pumps the fluid from the second port 112 into the fluid passage 119. the second first connection pipe 201 feeds the liquid or gas to the first port 111). In other examples, the two first connection pipes 201 may also extract fluid or liquid or gas at the same time, that is, both the two first connection pipes 201 are used for extracting fluid or inputting liquid or gas, which may be achieved by the two first connection pipes 201, and of course, the specific delivery types of the two first connection pipes 201 may be set according to different situations, which is not limited herein.

Referring to fig. 1, 2 and 10, in another example, the number of the first connection pipes 201 is three, and the first control device 15 is used for pumping the fluid from the second port 112 into the fluid channel 119 through the first connection pipe 201; and for inputting liquid to the first port 111 through the second first connection pipe 201; and for inputting gas to the first port 111 through the third first connection pipe 201.

This arrangement enables each first connecting pipe 201 to be used individually for delivering different types of fluid, thus facilitating the control of the first control device 15. For example, the first control device 15 can simultaneously draw the fluid from the second port 112 into the fluid channel 119 via a first connecting line 201, feed the fluid to the first port 111 via a second first connecting line 201, and feed the gas to the first port 111 via a third first connecting line 201. For another example, the first control device 15 can simultaneously control the first connection pipe 201 to pump the fluid from the second port 112 into the fluid channel 119, the second first connection pipe 201 to supply the fluid to the first port 111, and the third first connection pipe 201 not to supply the gas to the first port 111. As is apparent from the above description, the first control device 15 can control the operation in the first connecting pipe 201 differently according to the situation.

Further, taking the household appliance 20 as an electric cooker as an example, in a case that the number of the first connection pipes 201 is one, the first connection pipes 201 need to be used for not only extracting rice washing water in the electric cooker, but also introducing clean water or gas into the electric cooker, so that the clean water or gas may bring the rice scale attached to the inner wall of the first connection pipe 201 into the electric cooker when flowing in the first connection pipes 201, which may cause a large amount of rice scale in the electric cooker and affect the quality of the rice cooked by the electric cooker.

The number of the first connecting pipes 201 is three, so that the defects can be effectively solved, and the working quality of the electric cooker is improved.

In the above example, the number of the first ports 111 is three, and three different first connection pipes 201 are connected to different ones of the first ports 111, respectively. At this time, simultaneous operation of the three first connection pipes 201 can be achieved. That is, at this time, the first connection tube 201 draws the fluid of the second port 112 into the fluid passage 119. The second first connection pipe 201 inputs liquid to the first port 111. The third first connection pipe 201 inputs gas to the first port 111. When the number of the first ports 111 is one or two, since the three first connection pipes 201 are not connected to different first ports 111, the three first connection pipes 201 cannot be operated at the same time.

Further, in the above example, three first connection pipes 201 are used for different delivery, respectively (the first connection pipe 201 pumps the fluid from the second port 112 into the fluid passage 119. the second first connection pipe 201 inputs the liquid to the first port 111. the third first connection pipe 201 inputs the gas to the first port 111). In other examples, the three first connection pipes 201 may also extract fluid or liquid or gas at the same time, that is, all of the three first connection pipes 201 are used for extracting fluid or inputting liquid or gas, which may be achieved by the three first connection pipes 201, and of course, specific delivery types of the three first connection pipes 201 may be set according to different situations, which is not limited herein.

Further, the above is only for the case that the number of the first connection pipes 201 is one, two, and three, and in other embodiments, the number of the first connection pipes 201 may also be four, five, or six, wherein a plurality of first connection pipes 201 may be respectively used for conveying different fluids or conveying the same fluid, and may be specifically set according to different situations, and the specific number of the first connection pipes 201 is not limited herein.

Referring to fig. 1, 2 and 11, in some embodiments, the household appliance 20 includes a second connection pipe 202 and a third connection pipe 203, and the first connection pipe 201 is used to communicate with the second connection pipe 202 or with the third connection pipe 203;

in the case where the first connection pipe 201 is communicated with the second connection pipe 202, the first control device 15 is configured to supply the liquid to the first port 111 through the second connection pipe 202 and the first connection pipe 201 so that the liquid flows to the second port 112 through the fluid passage 119;

in the case where the first connection pipe 201 is communicated with the third connection pipe 203, the first control device 15 serves to supply gas to the first port 111 through the third connection pipe 203 and the first connection pipe 201 so that the gas flows to the second port 112 through the fluid passage 119.

Thus, the number of the connection pipes of the household electrical appliance 20 can be reduced, and the manufacturing cost of the household electrical appliance 20 is reduced, which is beneficial to mass production of the household electrical appliance 20.

Under the condition that first connecting pipe 201 and second connecting pipe 202 communicate, first connecting pipe 201 and second connecting pipe 202 are used for carrying liquid, under the condition that first connecting pipe 201 and third connecting pipe 203 communicate, first connecting pipe 201 and third connecting pipe 203 are used for conveying gas, so, through dividing the pipe setting, be favorable to first controlling means 15's control, and then prevent the condition of unusual transport from appearing.

In the case where the household appliance 20 is an electric cooker, for example, the abnormal transportation means that, when only the second connection pipe 202 (or the third connection pipe 203) is provided, the second connection pipe 202 is required to transport liquid or gas, and since part of the liquid may remain in the second connection pipe 202 when the liquid is transported, in this case, when the gas is transported through the second connection pipe 202, the liquid remaining in the second connection pipe 202 may be transported into the electric cooker together, so that the weight of the liquid in the electric cooker may be increased, and the quality of rice cooked by the electric cooker may be affected, and the second connection pipe 202 and the third connection pipe 203 may be provided to effectively prevent the above situation, where the second connection pipe 202 is only used to transport liquid, and the third connection pipe 203 is only used to transport gas. Of course, in other embodiments, the second connection pipe 202 can be used for conveying gas, and the third connection pipe 203 can be used for conveying liquid, and the specific arrangement mode can be set according to different situations.

Referring further to fig. 1, 2 and 11, in some embodiments, the household appliance 20 includes a first reversing element 211, the first reversing element 211 is connected to the first connecting tube 201, the second connecting tube 202 and the third connecting tube 203, and the first reversing element 211 is used to connect the first connecting tube 201 to the second connecting tube 202 or to connect the first connecting tube 201 to the third connecting tube 203.

As such, it is more convenient for the first connection pipe to communicate with the second connection pipe 202 or communicate with the third connection pipe 203.

Through the arrangement of the first reversing element 211, the first connecting pipe 201 is conveniently controlled to be communicated with the second connecting pipe 202 or the third connecting pipe 203, so that the situation that the first connecting pipe 201 is communicated with both the second connecting pipe 202 and the third connecting pipe 203 can be prevented.

In this embodiment, the first direction changing member 211 is a three-way member, such as a three-way valve.

Referring to fig. 1, 2 and 12, in some embodiments, the household appliance 20 includes a fourth connection pipe 204, the first control device 15 includes a liquid feeding part 151 and a gas feeding part 152, the fourth connection pipe 204 is connected to the liquid feeding part 151, and the liquid feeding part 151 is used for feeding liquid to the first connection pipe 201 through the fourth connection pipe 204 and the second connection pipe 202 in a case where the fourth connection pipe 204 is communicated with the second connection pipe 202 and the second connection pipe 202 is communicated with the first connection pipe 201.

In the case where the fourth connection pipe 204 is disconnected from the second connection pipe 202 and the third connection pipe 203 is communicated with the first connection pipe 201, the gas supply part 152 serves to supply gas to the first connection pipe 201 through the third connection pipe 203.

In this way, the household appliance 20 is facilitated to perform different functions.

With this arrangement, in the case where the fourth connection pipe 204 is communicated with the second connection pipe 202 and the second connection pipe 202 is communicated with the first connection pipe 201, the liquid feeding part 151 can feed the liquid through the fourth connection pipe 204, the second connection pipe 202 and the first connection pipe 201, and in the case where the fourth connection pipe 204 is disconnected from the second connection pipe 202 and the third connection pipe 203 is communicated with the first connection pipe 201, the liquid feeding part 151 cannot feed the liquid through the fourth connection pipe 204, the second connection pipe 202 and the first connection pipe 201. At this time, the gas supply member 152 can supply the gas to the first connection pipe 201 through the third connection pipe 203. This not only facilitates the operation of the first control device 15, but also is simple in structure and easy to implement.

Further, the liquid feeding part 151 may be a water tank connected to the fourth connection pipe 204, and the water tank inputs water in the water tank into the second connection pipe 202 through the fourth connection pipe 204. It is understood that the liquid feeding part 151 may be not only a water tank, but a specific type of the liquid feeding part 151 may be set according to various situations. For example, in other embodiments, the liquid feeding part 151 may be an external tap or an external water supply device (water station).

Further, the gas supply part 152 may be a gas pump capable of generating gas and supplying the gas into the third connection pipe 203, and then into the first connection pipe 201 through the third connection pipe 203.

Wherein, the air pump can be electronic air pump, and the setting up of electronic air pump makes domestic appliance 20 more intelligent, and it can be understood that the air pump not only can be electronic air pump, can set up the specific type of air pump according to different situation.

The third direction changing element 213 serves to selectively communicate the sixth connection pipe 206 with the third connection pipe 303 or with the seventh connection pipe 207. When the sixth connection pipe 206 and the seventh connection pipe 207 are connected, the air supply member 14 supplies gas to the conveyance member 11 through the sixth connection pipe 206 and the seventh connection pipe 207 to extend the conveyance member 11.

Further, the household appliance 20 further comprises an eighth connection pipe 208, and the eighth connection pipe 208 connects the feeding part 14 and the third reversing element 213.

In some embodiments, the delivery member 11 includes a retraction assembly 110 and a delivery tube 118 coupled to the retraction assembly 110, the delivery tube 118 defining a fluid passageway 119, and the first control 15 is configured to deliver fluid into the retraction assembly 110 to extend the actuation retraction assembly 110.

Therefore, the telescopic assembly 110 is driven by fluid, and has a simple structure and is easy to realize.

Wherein, flexible subassembly 110 includes first mouth 111 and second mouth 112, and the upper and lower direction is flexible direction of flexible subassembly 110, and along upper and lower direction, flexible subassembly 110 has both ends, and the both ends of flexible subassembly 110 are provided with first mouth 111 and second mouth 112 respectively. Further, the telescopic assembly 110 has a top portion 113 and a bottom portion 116 at two ends thereof, the first port 111 is disposed at the top portion 113, and the second port 112 is disposed at the bottom portion 116.

The delivery pipe 118 is disposed inside the telescopic assembly 110, and the delivery pipe 118 can be vertically extended and retracted in cooperation with the telescopic assembly 110. The delivery pipe 118 is a hollow structure, and one end of the delivery pipe 118 is connected to the first port 111 and the other end is connected to the second port 112 to form a fluid passage 119. Thus, via the first port 111, fluid can flow along the fluid passage 119 to the second port 112, thereby performing a water inlet function. It is understood that in other embodiments, a portion of the delivery tube 118 may be disposed within the retraction assembly 110, another portion may be disposed outside of the retraction assembly 110, and a portion of the delivery tube 118 disposed within the retraction assembly 110 may communicate with the second port 112.

Accordingly, via the second port 112, fluid may flow along the fluid passage 119 to the first port 111, performing a pumping function. Meanwhile, the telescopic assembly 110 drives the conveying pipe 118 to extend and retract in the up-and-down direction, so that the conveying part 11 can occupy a small space. Preferably, the first port 111 and the second port 112 are provided at the top portion 113 and the bottom portion 116, respectively, in the central axis direction. Thus, the processing is convenient.

Further, in some embodiments, the fluid channel 119 is used to selectively deliver liquid or gas entering from the first port 111 to the second port 112. Referring to fig. 18, when the fluid is a liquid, the liquid may flow from the first port 111 to the second port 112, or may flow from the second port 112 to the first port 111; when the fluid is a gas, the gas may flow from the first port 111 to the second port 112, or may flow from the second port 112 to the first port 111. In this manner, the fluid passage 119 may be used to perform the functions of water intake, water pumping, and air intake of the delivery member 11.

It is noted that the fluid passage 119 may be open to one of a liquid and a gas. That is, when the fluid passage 119 is filled with liquid, no gas is filled in the fluid passage 119; when the fluid passage 119 is filled with gas, no liquid is filled in the fluid passage 119.

Further, referring to fig. 18 and 19, in some embodiments, telescoping assembly 110 includes a plurality of telescoping members 12, each telescoping member 12 having a hollow configuration, and telescoping assembly 110 further includes a first end member 114 coupled to one of telescoping members 12 and positioned at top 113 and a second end member 117 coupled to another of telescoping members 12 and positioned at bottom 116. The plurality of telescopic members 12 are sequentially sleeved along the telescopic direction, and the delivery pipe 118 is accommodated in the telescopic members 12 and extends from the top portion 113 to the bottom portion 116. Thus, the telescoping effect of the telescoping assembly 110 can be achieved.

Specifically, the plurality of telescopic members 12 are all of a cylindrical structure, one of the telescopic members 12 is located at the top portion 113 and is fixedly connected to the first end member 114, and the other telescopic members 12 are sequentially sleeved on the telescopic member 12 located at the top portion 113 and extend to the bottom portion 116.

Further, the first end member 114 is formed with a first port 111, the second end member 117 is formed with a second port 112, the plurality of expansion members 12, the first end member 114 and the second end member 117 together define a receiving space 120, the delivery tube 118 is disposed in the receiving space 120, and the delivery tube 118 is received in the receiving space 120. Thus, the duct 118 can be isolated from the outside space while having a telescopic effect, and a protective effect on the duct 118 can be provided.

In one example, the plurality of telescoping members 12 are each circular in cross-section in the up-down direction, which provides the telescoping assembly 110 with greater strength. In other embodiments, the cross section of the plurality of telescopic members 12 in the up-down direction may be rectangular, triangular, or the like.

Further, in the present embodiment, the delivery pipe 118 is stacked from the first port 111 to the second port 112 and disposed in the housing space 120, specifically, the length of the delivery pipe 118 is greater than the linear distance between the first port 111 and the second port 112, and preferably, the delivery pipe 118 is spiral-shaped from the first port 111 to the second port 112. In this manner, the delivery tube 118 can be stacked and has a minimum stretchable length corresponding to the telescopic assembly 110, so that the delivery tube 118 can be easily installed and detached, and the situation that the delivery tube 118 is separated from the first port 111 and/or the second port 112 and is broken to cause the fluid passage 119 to be unable to communicate when being stretched in the up-down direction is avoided.

Further, in some embodiments, the plurality of telescoping members 12 includes a first telescoping member 121 and a second telescoping member 124 nested within each other, the second telescoping member 124 slidably nested within the first telescoping member 121. Referring to fig. 20 and 22, specifically, the cross-sectional area of the first telescopic member 121 in the vertical direction is larger than the cross-sectional area of the second telescopic member 124, and the second telescopic member 124 can slide on the first telescopic member 121 in the vertical direction, so that the second telescopic member 124 can be accommodated in the hollow structure of the first telescopic member 121.

Preferably, a sealing member 13 is disposed between the first telescopic member 121 and the second telescopic member 124, and the sealing member 13 seals a gap between the first telescopic member 121 and the second telescopic member 124 to form the receiving space 120. In this way, the sealing member 13 can be used to seal the receiving space 120.

Further, in some embodiments, the sealing member 13 includes a mounting portion 131 and a resilient sealing arm 134 extending from the mounting portion 131, referring to fig. 21 and 23, the mounting portion 131 is annularly defined and fixed on an outer side wall surface of the second telescopic member 124, the resilient sealing arm 134 is elastically abutted from the mounting portion 131 to an inner side wall surface of the first telescopic member 121, and a movable space for elastic deformation of the resilient sealing arm 134 is formed between the mounting portion 131 and the resilient sealing arm 134.

Specifically, when the elastic sealing arm 134 elastically abuts against the inner side wall of the first telescopic member 121, the elastic sealing arm 134 elastically deforms and is pressed into the active space, and since the active space is sufficient to accommodate the elastic sealing arm 134, the elastic sealing arm 134 cannot be attached to the surface of the mounting portion 131 located in the active space, and the elastic sealing arm 134 only exerts an elastic force generated by its elastic deformation on the inner side wall of the first telescopic member 121. Thus, the sealing element 13 does not generate excessive friction on the inner side wall of the first telescopic element 121 while achieving the sealing effect, and the mounting portion 131 is tightly attached to the outer side wall surface of the second telescopic element 124, so that when the second telescopic element 124 slides on the first telescopic element 121, the situation that the sealing element 13 is rolled on the outer side wall surface of the second telescopic element 124 due to the fact that the second telescopic element 124 drives the sealing element 13 to deviate can be avoided.

Preferably, the second telescopic member 124 is formed with a groove 129, and the mounting portion 131 is fixed in the groove 129, and the groove 129 may serve to confine the sealing member 13 to the second telescopic member 124 and also prevent the sealing member 13 from being rolled up.

Further, in some embodiments, the elastic sealing arm 134 includes a first arm 135 extending obliquely upward from the mounting portion 131 in the extending direction and a second arm 136 connecting an end of the first arm 135 away from the mounting portion 131. The mounting portion 131 is arranged along the vertical direction and has a top end 132 and a bottom end 133, the top end 132 and the bottom end 133 are respectively abutted to two sides of the inner wall of the groove 129 in an interference manner, the first arm 135 extends upwards from the bottom end 133 of the mounting portion 131 along the direction B and is connected to the second arm 136, the second arm 136 extends upwards from the first arm 135 along the direction C, and an included angle is formed between the extending portion of the first arm 135 along the direction B and the mounting portion 131. In this way, the elastic sealing arm 134 and the mounting portion 131 are spaced to form a movable space. In one example, the C direction is parallel to the telescoping direction.

Preferably, the included angle is an acute angle, please refer to fig. 21, so that when the first expansion member 121 is sleeved to the second expansion member 124, the elastic sealing arm 134 can have a guiding function, so as to facilitate the sliding of the second expansion member 124 along the inner sidewall of the first expansion member 121.

Further, in some embodiments, referring to fig. 20, the first telescopic member 121 includes a first cylinder 122 and a first stop edge 123 extending from the first cylinder 122 into the first cylinder 122, and correspondingly, the second telescopic member 124 includes a second cylinder 125 and a second stop edge 126 extending from the second cylinder 125 to the outside of the second cylinder 125, the second stop edge 126 is used for cooperating with the first stop edge 123 to limit the telescopic distance between the first telescopic member 121 and the second telescopic member 124, and the second stop edge 126 defines a groove 129.

Specifically, the first stopping edge 123 extends radially on the inner side wall of the bottom of the first cylinder 122 and is formed with a through hole for the second cylinder 125 to pass through. Correspondingly, the second stopping edge 126 includes a first stopping edge 127 and a second stopping edge 128, the first stopping edge 127 and the second stopping edge 128 respectively extend in the radial direction on the outer side walls of the top and the bottom of the second cylinder 125, the thickness of the first stopping edge 123 is greater than that of the first stopping edge 127, when the second cylinder 125 penetrates through the first cylinder 122, the first stopping edge 123 can limit the sliding direction of the second cylinder 125 on the inner side wall of the first cylinder 122, and the first stopping edge 127 and the first stopping edge 123 cooperate to limit the downward telescopic distance of the second cylinder 125.

Similarly, second flange 128 cooperates with first flange 123 to limit the upward telescoping distance of second barrel 125 such that first flange 123 and second flange 126 cooperate to retain second telescoping member 124 for sliding movement within first barrel 122. In one example, the position of first rib 127 and second rib 128 on second barrel 125 can be freely adjusted. The specific values of the positions of the first rib 127 and the second rib 128 are not limited herein.

The groove 129 is formed in the second cylinder 125 in an annular shape, and two corresponding annular side plates are formed in the vertical direction, the first rib 127 forms one side plate of the groove 129, the other side plate of the groove 129 is located above the second rib 126 in the vertical direction, and the top end 132 and the bottom end 133 are respectively abutted to the two side plates of the groove 129 in an interference manner. Thus, the second stopping edge 126 is provided to eliminate the need for a side plate for the groove 129, and to simplify the structure.

In addition, first rib 127 and/or second rib 128 can be removably coupled to second cylinder 125, in one example, first rib 127 is removably coupled to second cylinder 125, and preferably, second rib 128 is removably coupled to second cylinder 125. In this way, the second telescopic member 124 is conveniently slid into the top of the first cylinder 122 along the inner side wall of the first cylinder 122.

In some embodiments, the first end member 114 defines a third opening 115 communicating with the receiving space 120, referring to fig. 18 and 19, the third opening 115 is used for introducing air into the receiving space 120 to drive the expansion assembly 110 to expand.

Specifically, since the receiving space 120 is sealed by the sealing member 13 and the sealing process is also performed between the telescopic member 12 and the first end element 114 and between the telescopic member 12 and the second end element 117, the gas introduced into the receiving space 120 along the third opening 115 generates pressure on the inner wall of the telescopic member 12 and can push the plurality of telescopic members 12 to sequentially extend in the up-down direction, for example, the second telescopic member 124 slides downward along the inner sidewall of the first telescopic member 121 after being pushed by the gas pressure. In this manner, a stretching effect of the retraction assembly 110 is achieved.

Further, in some embodiments, the conveying component 11 comprises a restoring member 137 connecting the plurality of telescopic members 12, preferably, the restoring member 137 is disposed between two telescopic members 12 which are sleeved, and the restoring member 137 is used for keeping the plurality of telescopic members 12 in a contracting tendency.

Specifically, referring to fig. 20, an accommodating space 138 is defined among the first retaining edge 127, the first cylinder 122, the second cylinder 125 and the first retaining edge 123, the restoring member 137 is disposed in the accommodating space 138, the restoring member 137 has two ends along the direction of maximum elastic deformation, one end of the restoring member 137 abuts against the bottom of the first retaining edge 127, and the other end of the restoring member 137 abuts against the top of the first retaining edge 123.

Specifically, the fluid is gas, when the gas enters the accommodating space 120 along the third opening 115, the second expansion piece 124 is pushed by the gas pressure to slide downward along the inner side wall of the first expansion piece 121, and meanwhile, the reset piece 137 is squeezed in the accommodating space 138 to be elastically deformed, so that the reset piece 137 has a tendency that the second expansion piece 124 slides and contracts into the first expansion piece 121; when the gas is exhausted from the receiving space 120 along the third opening 115, the restoring member 137 restores and pushes the first rib 127 upward, and the second expansion member 124 finally slides and contracts into the first expansion member 121. In this manner, the retraction effect of retraction assembly 110 is achieved. When the fluid is liquid, the action principle is similar to that when the fluid is gas, and will not be described herein.

In one example, the upper surface of the first stopper 123 is provided with a flange for defining the restoring member 137, and the flange has the effect of thickening the first stopper 123. Thus, the first stopping edge 123 has a certain strength, so that the situation that the first stopping edge 123 is separated from the first cylinder 122 or is broken due to the overlarge elastic force exerted by the resetting piece 137 on the first stopping edge 123 is avoided.

Additionally, in one example, restoring member 137 can resiliently couple top portion 113 and first telescoping member 121, and/or restoring member 137 can resiliently couple top portion 113 and second telescoping member 124, in another example, restoring member 137 can be provided outside of the overall structure of telescoping assembly 110.

In addition, the restoring member 137 may be a hydraulic member, a pneumatic member (e.g., a cylinder), a motor, and a magnetic member, and the driving principle is similar to that of the elastic member, and thus, will not be described in detail. In the case that the reset member includes a magnetic member, the magnetic member may include a permanent magnetic member, and may also include an electromagnetic member, and the second telescopic member 124 slides in the telescopic direction within the first telescopic member 121 by the acting force (including the attractive force or the repulsive force) of the two magnetic members. In one example, the first stopping edge 123 is provided with a permanent magnetic member, and the second stopping edge 126 is provided with an electromagnetic member, so that the sliding of the second telescopic member 124 is realized by changing the magnetism of the electromagnetic member so that the first stopping edge 123 and the second stopping edge 126 attract or repel each other. In another example, the first stop edge 123 and the second stop edge 126 are each provided with an electromagnetic member. The restoring member may also include a combination of two or more of an elastic member, a hydraulic member, a pneumatic member, a motor, and a magnetic member, and other embodiments are not specifically limited herein.

It is understood that in this embodiment, the first telescopic member 121 and the second telescopic member 124 do not only refer to two specific telescopic members 12 sleeved with each other in the telescopic assembly 110, but only for clearly describing the specific related structure for realizing the telescopic function between two adjacent telescopic members 12, any two telescopic members 12 sleeved and connected have the same or similar specific structure between the first telescopic member 121 and the second telescopic member 124. In particular, in the illustrated embodiment, the number of telescopic elements 12 is four, namely

telescopic elements

12a, 12b, 12c, 12d, in the first case the first telescopic element being 12a and the second telescopic element being 12 b; in the second case, the first telescopic member may be 12b and the second telescopic member may be 12 c; in a third case, the first telescoping member may be 12c and the second telescoping member may be 12 d. It is understood that in other embodiments, the number of telescoping members 12 can be any number, and is provided according to the specific situation, and the number of telescoping members 12 is not limited herein.

Referring to fig. 1, fig. 2 and fig. 24, in some embodiments, the feeding component 14 includes a quantitative cavity 141 and a switch 142 movably disposed relative to the quantitative cavity 141, the quantitative cavity 141 is provided with a quantitative cavity 1411 and a discharge opening 1412, the quantitative cavity 1411 is used for accommodating materials, and the quantitative cavity 1411 is communicated with the discharge opening 1412; the switch piece 142 is used for closing the feed opening 1412 or opening the feed opening 1412;

the first control device 15 is used for driving the switch piece 142 to move relative to the quantitative cavity 141, so that the switch piece 142 opens the feed opening 1412 and/or closes the feed opening 1412.

Thus, the opening and closing of the feed opening 1412 are conveniently controlled, and the quantity of the material falling from the feed opening 1412 is controlled.

Specifically, the switch member 142 is formed with a slope 1421 inclined toward the axial direction L of the discharge port 1412 in the circumferential direction, so that when the switch member 142 opens the discharge port 1412, the material is guided and dispersed by the slope 1421, and the material is prevented from forming a material peak at a position corresponding to the discharge port 1412 in the quantitative chamber 1411.

Referring to fig. 7, in some embodiments, the quantitative cavity 141 of the feeding member 14 may be a hollow structure. The bottom of the quantitative cavity 141 is tapered. This facilitates the fall of the material in the dosing chamber 141. Of course, the bottom of the quantitative cavity 141 may not only be tapered, but the specific shape of the bottom of the quantitative cavity 141 may be set according to different situations. The specific shape of the bottom of the quantitative cavity 141 is not limited herein.

In the above embodiment, the quantitative cavity 141 is formed at the bottom thereof with the discharge port 1412, and the switch member 142 may have a valve structure that can open or close the discharge port 1412. The valve structure may be an electronic valve, and the electronic valve includes a driving element and a moving plate connected to the driving element, and the driving element is used to drive the moving plate to move so that the moving plate opens or closes the feed opening 1412. Alternatively, the valve structure may open or close the feed opening 1412 under the force of gravity of the material. As can be seen from the above description, the valve structure may be a mechanical valve structure (the discharge opening 1412 is opened or closed by gravity) or an electronic valve (the moving plate is driven by the driving element to move to open or close the discharge opening 1412), and the specific type of the valve structure may be specifically set according to different situations, and only the valve structure is required to open or close the discharge opening 1412. The specific type of valve structure is not limited herein.

Referring to fig. 3 and 4, in some embodiments, the conveying member 11 is disposed outside the quantitative cavity 141, and one end of the conveying member 11 is connected to the switch 142, so that the conveying member 11 drives the switch 142 to move together during the expansion and contraction process, and the switch 142 can open or close the discharging opening 1412. As shown in fig. 3, during the extension of the conveying member 11, the switch piece 142 moves downward along with the conveying member 11, so that the switch piece 142 is separated from the discharge opening 1412 to open the discharge opening 1412 to allow the material in the quantitative cavity 141 to fall from the discharge opening 1412. As shown in fig. 4, during the shortening of the conveying member 11, the switch member 142 moves upward along with the conveying member 11, so that the switch member 142 can close the discharge opening 1412 so that the material in the quantitative cavity 141 cannot fall from the discharge opening 1412.

In both embodiments, the user can pour the material (e.g., rice) into the feeding part 14, and then the valve structure or the conveying part 11 operates to open the discharge opening 1412 so that the material in the quantitative chamber 141 falls out of the discharge opening 1412.

It is to be understood that, in the above embodiment, the conveying member 11 is disposed at a distance from the quantitative cavity 141. Thus, the quantitative cavity 141 and the conveying component 11 are arranged at an interval, which can prevent the feeding component 14 and the conveying component 11 from interfering with each other during operation, and is beneficial to the operation of the household appliance 20. That is, the conveying member 11 is used for conveying fluid, the feeding member 14 is used for receiving and feeding material, and both can be operated independently.

Of course, the above two embodiments are merely illustrative of the operation of the switch member 142. In other embodiments, the operation of the switch member 142 includes not only the above two. For example, in some embodiments, the following drive device 215 may also be used to control the operation of the switch member 142. The specific operation can be selected according to actual conditions, and the specific operation mode of the switch element 142 is not limited herein.

It is understood that, referring to fig. 5 and 6, in other embodiments, the conveying component 11 may be disposed inside the quantitative cavity 141 of the feeding component 14. In this case, the switch member 142 is connected to one end of the conveying member 11, so that the conveying member 11 can drive the switch member 142 to move during the expansion and contraction process, and the switch member 142 can open or close the discharging opening 1412. As shown in fig. 5, during the extension of the conveying member 11, the switch piece 142 moves downward along with the conveying member 11 so that the switch piece 142 is separated from the discharge opening 1412 to open the discharge opening 1412 so that the material in the quantitative cavity 141 can fall from the discharge opening 1412. As shown in fig. 6, during the shortening of the conveying member 11, the switch member 142 moves upward along with the conveying member 11, so that the switch member 142 can close the discharge opening 1412 so that the material in the quantitative cavity 141 cannot fall from the discharge opening 1412.

Referring to fig. 1 to 6 and 24, the switch element 142 is disposed in the middle of the quantitative cavity 1411, which facilitates the arrangement between the switch element 142 and the quantitative cavity 1411. Preferably, in the orientation of fig. 1 and 2, the switch member 142 is disposed in a vertical direction in the middle of the dosing chamber 1411.

In some embodiments, referring to fig. 1, 2 and 24, the household appliance 20 includes a driving device 215, the driving device 215 includes a fixed member 2151 and a moving member 2152, the fixed member 2151 is disposed in the dosing chamber 1411, the moving member 2152 is connected to the switch member 142, the moving member 2152 is partially received in the fixed member 2151 and can move relative to the fixed member 2151, and the switch member 142 is connected to the moving member 2152 and moves along with the moving member 2152.

Specifically, one end of the eighth connecting pipe 208 is communicated with the fixing member 2151, and when the sixth connecting pipe 206 is communicated with the eighth connecting pipe 208, the air supply member 152 supplies air into the fixing member 2151 through the sixth connecting pipe 206 and the eighth connecting pipe 208 to move the moving member 2152, thereby moving the switch member 142. And the moving member 2152 can be reset by the reset member 137. Specifically, the driving device 215 includes a restoring member 137, the restoring member 137 is connected to the moving member 2152, and the restoring member 137 is used for providing a force to the moving member 2152 to enable the switch member 142 to close the discharge opening 1412.

The restoring member 137 may include at least one of the following structures: elastic component, hydraulic pressure spare, air casting die, motor, magnetic part. In the illustrated embodiment, the restoring member 137 includes an elastic member, such as a spring. The elastic member is located in the fixing member 2151, and one end of the elastic member abuts against the bottom surface in the fixing member 2151 and the other end abuts against one end of the moving member 2152 located in the fixing member 2151, so that the elastic member provides an upward thrust to the moving member 2152. In the absence of gas pressure, the moving member 2152 allows the switching member 142 to maintain the state of closing the discharge opening 1412 under the action of the elastic member. Under the condition that the moving member 2152 is driven to move downwards by the gas pressure, the elastic member is compressed, and the moving member 2152 drives the switch member 142 to move downwards to open the discharge opening 1412. When the gas pressure is removed, the elastic member drives the moving member 2152 to reset and move upwards, so as to drive the switch member 142 to close the discharge opening 1412 again and keep the switch member 142 in a state of closing the discharge opening 1412. In another embodiment, an elastic member may be connected to the top of the moving member 2152, and the elastic member provides an upward pulling force to the moving member 2152 to maintain the switching member 142 in a state of closing the discharge opening 1412 in the absence of gas pressure. It will be appreciated that the upward pushing and/or pulling force may also be provided by two or more elastic members. The driving principle of the hydraulic part, the pneumatic part, the motor and the magnetic part is similar to that of the elastic part, and the driving principle is not expanded in detail. In addition, in the case where the restoring member 137 includes a magnetic member, the magnetic member may include a permanent magnetic member, or may include an electromagnetic member. The moving member 2152 may itself be magnetic or another magnetic member may be fixed to the moving member 2152, and the moving member 2152 may be reset by the force (including attractive or repulsive force) of the two magnetic members. The restoring member 137 may also include a combination of two or more of an elastic member, a hydraulic member, a pneumatic member, a motor, and a magnetic member.

The moving member 2152 may be connected to the switch member 142 by means of a snap fit, a thread, an interference fit, an adhesive, and the like, which is not limited herein.

In some embodiments, the first control device 15 is configured to drive the switch member 142 to move relative to the dosing chamber 141 by fluid means so that the switch member 142 opens the discharge opening 1412.

Thus, the open/close state of the switch member 142 is easily controlled.

In the above case, the moving member 2152 is moved by the gas supply part 152, that is, the gas supply part 152 can supply not only the gas flow but also the gas to the feeding part 14 to the feeding part 11, so that the structure of the home appliance 20 is more simplified.

It will be appreciated that in other embodiments, the first control device 15 may also comprise a drive component which solely supplies the feeding component 14 with fluid, for example, in an example, the air supply component 152 is connected only to the feeding component 11, that is, in such an example, the eighth connecting pipe 208 of the household appliance 20 is not connected to the third reversing element 213, one end of the eighth connecting pipe 208 remote from the feeding component 14 is directly connected to the drive component, and the drive component supplies fluid to the feeding component 14 directly through the eighth connecting pipe 208 so that the switch member 142 is movable relative to the dosing cavity 141 to cause the switch member 142 to open the discharge opening 1412, and it is noted that in such an example, the third reversing element 213 is a one-in two-out solenoid valve.

Further, in the above example, the driving part includes at least one of the following structures: cylinder, hydro-cylinder, electromagnetism spare, motor. In the case where the driving member is an oil cylinder, the principle and structure for driving the movement of the shutter 142 using the structure of the oil cylinder are similar to those for driving the movement of the shutter 142 using the air feeding member 152. In case that the driving part includes a motor, the household appliance 20 is not provided with the eighth connection pipe 208 at this time, and the motor may be connected with the moving member 2152 through a transmission assembly including, but not limited to, a belt, a gear, a screw, a hinge, etc. In the case where the driving member includes an electromagnetic member, and the household appliance 20 is not provided with the eighth connection pipe 208 at this time, the moving member 2152 itself may be magnetic or the magnetic member may be fixed on the moving member 2152, and the moving member 2152 is moved by the force (including an attractive force or a repulsive force) of the electromagnetic member on the magnetic member. Of course, the driving component may also include a combination of two or more of a cylinder, a motor, and an electromagnetic component.

In summary, the first control device 15 can be used to drive the moving member 2152 to move by means of fluid (fluid can include liquid and gas, and liquid can be water, oil, etc.) so that the switch member 142 moves relative to the dosing cavity 141 to open the discharge opening 1412. The moving member 2152 can also be controlled to move directly by a motor or an electromagnetic member so that the switch member 142 moves relative to the dosing cavity 141 to open the discharge opening 1412. The specific design can be designed according to the actual situation, and only the first control device 15 needs to be enabled to directly or indirectly drive the moving member 2152 to move so that the switch member 142 moves relative to the quantitative cavity 141 to open the discharge opening 1412.

Specifically, the storage device 214 is communicated with the quantitative cavity 1411 through the ninth connecting pipe 209, and the blower (suction fan) is communicated with the quantitative cavity 1411 through the tenth connecting pipe 210, so that when the blower works, an airflow from the storage device 214 to the quantitative cavity 1411 can be established in the ninth connecting pipe 209, the quantitative cavity 1411 and the tenth connecting pipe 210, and thus, the material in the storage device 214 can be sucked into the quantitative cavity 1411.

Further, in other embodiments, in the feeding direction of the quantitative cavity 1411, a fan (blower) may be provided, and in the case that two fans are operated simultaneously, one fan blows the material into the quantitative cavity 1411, and the other fan draws the material into the quantitative cavity 1411.
