Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a drainer and a sink. Background Art

[0002] After the drainer of the kitchen sink is used for a long time, food residues are likely to accumulate on its filter screen, which not only affects the drainage speed, but also easily mildews and rots, affecting the user experience. Common cleaning of the filter screen includes flushing with water, but flushing usually cannot effectively remove viscous residues. It is necessary to invert the filter screen in the reverse direction and knock on the tabletop or the edge of the sink, so that the viscous food residues on the filter screen vibrate down, but it is necessary to clean the sink and the tabletop for the second time, and may damage the sink and the tabletop, and the user experience is poor. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a drainer and a sink, aiming to improve the convenience of users to clean the food residues accumulated on the filter screen.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A drainer, a first limiting member and a second limiting member are fixedly connected to the outside of the lifting rod; a filter screen is also included, the filter screen is movably sleeved outside the lifting rod, the filter screen is located between the first limiting member and the second limiting member, and the water inlet end of the filter screen faces the first limiting member. The filter screen can reciprocate axially along the lifting rod between the first limiting member and the second limiting member under the action of an external force, and the filter screen alternately impacts the first limiting member and the second limiting member during the movement process.

[0006] Further, the first limiting member is made of a rigid material, and the second limiting member is made of a flexible material.

[0007] Further, a drainage device is included, and the drainage device is provided with a drainage channel; a sealing device is sleeved outside the lifting rod, the sealing device is located at one end of the second limiting member away from the first limiting member, and one end of the lifting rod close to the sealing device is detachably and movably connected to the drainage device. The sealing device moves with the lifting rod, so that the sealing device has a first state of separating from the drainage device to open the drainage channel and a second state of being hermetically adapted to the drainage device to close the drainage channel.

[0008] Further, the drainage device includes a locking member, an insertion hole is provided axially along the locking member, one end of the lifting rod close to the sealing device is movably inserted into the insertion hole, and an elastic device that moves radially along the lifting rod is provided on the lifting rod. A clamping groove extending radially outward is provided on the hole wall of the insertion hole;

[0009] Further, when the elastic device is clamped in the clamping groove, the sealing device is in the first state; when the elastic device disengages from the clamping groove and moves along the water outlet direction until the sealing device is sealingly adapted to the water outlet device, the sealing device is in the second state.

[0010] Further, the filter screen is provided with a limiting post extending along the axis of the lifting rod. When the lifting rod is pressed so that the first limiting member abuts against the limiting post, the sealing device is in the second state.

[0011] Further, the water outlet device further includes a water passing member and a connecting ring sleeved outside the locking member. The cavity between the water passing member and the connecting ring forms a water passing cavity. The water passing member and the connecting ring are provided with communication holes communicating with the water passing cavity, thereby forming the water passing channel; and the side vertical surface of the water passing member is a conical surface with a gradually decreasing water passing area along the water outlet direction. When the sealing device is in the second state, the sealing device is sealingly adapted to the conical surface.

[0012] Further, the sealing device includes an upper pressing piece, a lower pressing piece, and a sealing ring installed between the upper pressing piece and the lower pressing piece and pressed tightly; when in the first state, the sealing ring is disengaged from the conical surface, and when in the second state, the sealing ring is sealingly adapted to the conical surface.

[0013] Further, the filter screen is provided with a filtering cavity recessed along the water outlet direction. The outer side of the edge of the filtering cavity is provided with a lapping edge extending radially outward. The radial dimension of the lapping edge is larger than the radial dimension of the water inlet of the water outlet cavity at the bottom of the water tank.

[0014] A water tank includes a tank body. The bottom surface of the tank body is provided with a downwardly recessed water outlet cavity. The water outlet device as described above is installed in the water outlet cavity. The gap between the water outlet cavity and the filter screen forms a water passing cavity; when the sealing device is in the first state, the water passing cavity communicates with the water passing channel, and when the sealing device is in the second state, the water passing cavity does not communicate with the water passing channel.

[0015] Further, when the lifting rod is in the first state, the first limiting member is flush with the bottom surface of the tank body or a part of the first limiting member is higher than the bottom surface of the tank body.

[0016] The beneficial effects of the present utility model are:

[0017] 1. A drainer proposed by the present utility model. When it is necessary to clean the filter screen, the user holds the other end of the lifting rod, makes the water inlet end of the filter screen face downwards, and shakes it up and down, so that the filter screen moves up and down, and alternately impacts the first limiting member and the second limiting member during the moving process, causing the filter screen to vibrate when impacted, thereby effectively removing dirt. During the cleaning process, there is no need to knock on the tabletop or the edge of the sink, and the residue can be directly vibrated into the garbage bag without secondary cleaning of the sink or the tabletop, while avoiding damage to the sink and the tabletop caused by impact.

[0018] 2. A drainer proposed by the present utility model. When the filter screen moves up to the highest point and impacts the second limiting member made of flexible material, the second limiting member absorbs part of the vibration, the vibration generated by the filter screen decreases, and the possibility of water stains and residue splashing upwards onto the user's hand is reduced. When falling, the filter screen impacts the first limiting member made of rigid material, causing a large vibration of the filter screen, thereby vibrating the viscous residue in the filter screen away from the filter screen, thus forming a slag cleaning process in which water stains and residue only fall and do not splash upwards onto the user's hand, improving the user experience.

[0019] 3. A drainer proposed by the present utility model. The filter screen is provided with a limiting column extending along the axis of the lifting rod. Press the lifting rod to make the first limiting member abut against the limiting column, restricting the downward pressing distance of the lifting rod and avoiding excessive downward pressing of the sealing device, which accelerates the aging of the sealing device.

[0020] 4. A drainer proposed by the present utility model. The sealing device includes an upper pressing piece, a lower pressing piece, and a sealing ring installed between the upper pressing piece and the lower pressing piece and tightly pressed. The upper pressing piece and the lower pressing piece increase the strength of the sealing ring and extend its service life.

[0021] 5. A drainer proposed by the present utility model. The outer side of the edge of the filtering cavity is provided with a lapping edge extending radially outwards. The radial dimension of the lapping edge is larger than the radial dimension at the water inlet orifice of the water outlet cavity of the sink. When the filter screen is installed in the water outlet cavity of the sink, it restricts the filter screen from falling, ensuring that there is always a drainage gap between the filter screen and the water outlet cavity.

[0022] 6. A sink proposed by the present utility model includes the beneficial effects of the drainer described above, and the first limiting member is flush with the bottom surface of the tank body or part of the first limiting member is higher than the bottom surface of the tank body, avoiding excessive interference of the first limiting member higher than the bottom surface of the tank body with the items to be cleaned in the tank body and affecting normal use.

Detailed implementation manners

[0032] Embodiment 1

[0033] The following will be combined with Figure 1-3 to describe this embodiment in detail.

[0034] A drainer, a first limiting member 40 and a second limiting member 50 are fixedly connected to the outside of the lifting rod; a filter screen 60 is further included. The filter screen 60 is movably sleeved on the outside of the lifting rod. The filter screen 60 is located between the first limiting member 40 and the second limiting member 50, and the water inlet end of the filter screen 60 faces the first limiting member 40. The filter screen 60 can reciprocate between the first limiting member 40 and the second limiting member 50 along the axial direction of the lifting rod under the action of an external force. When it is necessary to clean the sediment in the filter screen 60, such as Figure 2 As shown, turn the water inlet end of the filter screen 60 downward and shake it up and down. The filter screen 60 reciprocates between the first limiting member 40 and the second limiting member 50 along the axial direction of the lifting rod under the action of an external force, so that the filter screen 60 alternately impacts on the first limiting member 40 and the second limiting member 50, causing the filter screen 60 to vibrate when impacted, thereby effectively removing dirt. During the cleaning process, there is no need to knock on the tabletop or the edge of the sink 160. The residue can be directly vibrated into the garbage bag, without secondary cleaning of the sink 160 or the tabletop, and at the same time, damage caused by impact to the sink 160 and the tabletop can be avoided.

[0035] In this embodiment, as Figure 1 As shown, the first limiting member 40 is made of a rigid material, and the second limiting member 50 is made of a flexible material. Rigid materials have very high hardness. Common rigid materials include metals, concrete, and ceramics, while flexible materials have lower hardness and are more likely to deform under the action of an external force, including but not limited to rubber, foam, and cloth. Therefore, the first limiting member 40 is made of steel, and the second limiting member 50 is made of an elastic material. Specifically, when the filter screen 60 moves up to the highest point and impacts the second limiting member 50 made of a flexible material, the second limiting member 50 absorbs part of the vibration, and the vibration generated by the filter screen 60 is reduced, reducing the possibility of water stains and residues splashing up onto the user's hands. When falling, the filter screen 60 impacts the first limiting member 40 made of a rigid material, causing a large vibration of the filter screen 60, thereby vibrating the viscous residue in the filter screen 60 away from the filter screen 60, thus forming a slag cleaning process in which water stains and residues only fall and do not splash up onto the user's hand, improving the user experience.

[0036] In this embodiment, as Figure 1 As shown, it includes a drainage device provided with a drainage channel; a sealing device is sleeved outside the lifting rod. The sealing device is located on the side of the second limiting member 50 away from the first limiting member 40. One end of the lifting rod close to the sealing device is detachably and movably connected to the drainage device. The sealing device moves with the lifting rod, so that the sealing device has a first state of detaching from the drainage device to open the drainage channel and a second state of being hermetically adapted to the drainage device to close the drainage channel.

[0037] In this embodiment, as Figure 1As shown, the drainage device includes a locking member 801. An insertion hole 8011 is provided along the axial direction of the locking member 801. The other end of the lifting rod is movably inserted into the insertion hole 8011, and an elastic device 30 that moves radially along the lifting rod is provided. A clamping groove 8012 that extends radially outward along the hole wall of the insertion hole 8011 is provided. When the elastic device 30 is clamped in the clamping groove 8012, the sealing device is in the first state. When the clamping member disengages from the clamping groove 8012 and moves along the water outlet direction until the sealing device is sealingly adapted to the drainage device, the sealing device is in the second state.

[0038] In this embodiment, as Figure 1 shown, the filter screen 60 is provided with a limiting post 70 that extends along the axis of the lifting rod. When the lifting rod is pressed so that the first limiting member 40 abuts against the limiting post 70, the sealing device is in the second state. Specifically, the limiting post 70 is movably sleeved outside the lifting rod. The limiting post 70 can be connected to the filter screen 60 through threaded fit or integrally formed on the filter screen 60.

[0039] In this embodiment, as Figure 1 shown, the drainage device further includes a water passing member 90 and a connecting ring 100 sleeved outside the locking member 801. The water passing member 90 is sealingly adapted to form a flow-through cavity 110 between the cavity between the water passing member 90 and the connecting ring 100. The water passing member 90 and the connecting ring 100 are provided with communication holes communicating with the flow-through cavity 110, thereby forming a drainage channel; and the side vertical surface of the water passing member 90 is a conical surface 901 with a gradually decreasing water passing area along the water outlet direction. When the sealing device is in the second state, the sealing device is sealingly adapted to the conical surface 901.

[0040] In this embodiment, one end of the lock nut is provided with a limiting step. The water passing member 90 abuts against the limiting step, and the connecting ring 100 is connected to the other end of the lock nut through threaded fit. By rotating the lock nut, the water passing member 90 and the connecting ring 100 are sealingly adapted to the inner bottom surface and the outer bottom surface of the tank body 170.

[0041] In this embodiment, as Figure 3 shown, the sealing device includes an upper pressing piece 120, a lower pressing piece 140, and a sealing ring 130 installed between the upper pressing piece 120 and the lower pressing piece 140 and pressed tightly. The upper pressing piece 120 and the lower pressing piece 140 increase the strength of the sealing ring 130 and extend its service life. Further, when in the first state, the sealing ring 130 is separated from the conical surface 901. When in the second state, the sealing ring 130 is sealingly adapted to the conical surface 901. Further, the lower pressing piece 140 is provided with a positioning convex portion 1401, and the sealing ring 130 is provided with a positioning groove adapted to the positioning convex portion 1401, so that during the axial movement of the sealing device, it is ensured that the sealing ring 130 is fixed in the radial direction without deviation.

[0042] In this embodiment, as Figure 1As shown in the figure, the filter screen 60 is provided with a filtering cavity 601 that is recessed along the water outlet direction. At the outer edge of the filtering cavity 601, there is a lapping edge 602 that extends radially outward. The radial dimension of the lapping edge 602 is larger than the radial dimension at the water inlet orifice of the drain cavity 1701 of the sink 160. When the filter screen 60 is installed in the drain cavity 1701 of the sink 160, it restricts the filter screen 60 from falling, ensuring that there is always a drainage gap between the filter screen 60 and the drain cavity 1701. Further, the edge of the filter screen 60 forms the lapping edge 602 through a flanging process.

[0043] In this embodiment, the lifting rod includes an extension rod 201 and a convex rod 202. One end of the extension rod 201 is threadedly connected to a first limiting member 40. The other end of the extension rod 201 is provided with a second limiting member 50 and a sealing device. And one end of the convex rod 202 is threadedly connected to the other end of the extension rod 201, thereby pressing the second limiting member 50 and the sealing device against the other end of the extension rod 201. The convex rod 202 is further provided with an elastic device 30. Specifically, the side surface of the convex rod 202 is provided with a mounting hole arranged along its radial direction. The elastic device 30 includes a spring and a clamping member. One end of the spring abuts against the mounting hole, and the other end abuts against the clamping member, such that the clamping member is clamped in the clamping groove 8012 under the action of elastic force.

[0044] Embodiment Two

[0045] The following Figure 4-7 will elaborate on this embodiment in detail.

[0046] A sink 160 includes a tank body 170. As Figure 4-5 shown, the bottom surface of the tank body 170 is provided with a downwardly recessed drain cavity 1701. The drainer 10 as described above is installed in the drain cavity 1701. The gap between the drain cavity 1701 and the filter screen 60 forms a water passing cavity 180. When the sealing device is in the first state, the water passing cavity 180 communicates with the drain passage. When the sealing device is in the second state, the water passing cavity 180 does not communicate with the drain passage. As Figure 6 and Figure 7 shown, during installation, the water passing member 90 is sealingly adapted to the inside of the tank body 170, and the connecting pipe is sealingly adapted to the outside of the tank body 170. Specifically, an upper sealing ring 1501 is provided between the water passing member 90 and the bottom surface of the tank body 170, and a lower sealing ring 1502 is provided between the connecting ring 100 and the outer bottom of the tank body 170. By rotating the locking nut, the water passing member 90 and the connecting ring 100 are respectively sealingly adapted to the inner bottom surface and the outer bottom surface of the tank body 170.

[0047] In this embodiment, when the lifting rod is in the first state, the first limiting member 40 is flush with the bottom surface of the tank body 170 or a part of the first limiting member 40 is higher than the bottom surface of the tank body 170, avoiding that the first limiting member 40 being too much higher than the bottom surface of the tank body 170 interferes with the items to be cleaned in the tank body 170 and affecting normal use.

[0048] In this embodiment, the water tank 160 proposed has the following drainage and water storage working principles:

[0049] The elastic device 30 is snap-connected in the snap groove 8012, and the sealing device is in the first state, that is, the sealing ring 130 is separated from the water passing member 90, the water passing cavity 180 communicates with the water discharge channel, and the water tank 160 is in the drainage state, as Figure 6 shown. Press down the lifting rod, so that the elastic device 30 is separated from the snap groove 8012 until the first limiting member 40 abuts against the limiting column 70. The sealing device is in the second state, that is, the sealing ring 130 is sealingly adapted to the water passing member 90, blocking the communication between the water passing cavity 180 and the water discharge channel, and the water tank 160 is in the water storage state, as Figure 7 shown.

[0050] The above embodiments are only for explaining the technical concept and characteristics of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention.
