Description

Technical Field

[0001] The invention belongs to the technical field of basin drain parts and relates to a replacement core for a deodorizing basin. Background Art

[0002] The basin is a porcelain basin installed in the bathroom for washing face and hands. Basins are divided into two types according to the difference in installation: above-the-counter basin and under-the-counter basin. The basin that protrudes from the countertop is called an above-the-counter basin, and the basin that is completely sunken below the countertop is called an under-the-counter basin. Above-the-counter basins are more commonly used in families. Basins need to store water when in use, and after use, the sewage needs to be discharged to the sewer pipe through the drain through the drain. In order to avoid the backflow of odor in the sewer pipe, the drain is often equipped with an anti-odor plug.

[0003] The patent with the authorization announcement number CN214033924U discloses an anti-odor and anti-blocking drainer including a drainer shell, a pressing surface cover installed on the drainer shell, and an anti-odor mechanism, the pressing surface cover includes a pressing cylinder, the axial direction of the pressing cylinder is parallel to the direction from the water inlet of the shell to the water outlet of the shell, the pressing cylinder includes a first limit part and a second limit part, the first limit part and the second limit part are spaced apart along the axial direction of the pressing cylinder; and a pressing cylinder core, the pressing cylinder core is telescopically installed on the pressing cylinder and connected to the surface cover body, and the pressing cylinder core moves between the first limit part and the second limit part. The above drainer is provided with a pressing bounce mechanism, which can conveniently realize different modes of water storage and drainage by operating the pressing surface cover.

[0004] The patent with authorization announcement number CN218322996U discloses a new type of odor-proof bouncing drain, which can be opened or closed by pressing the bouncing core when needed, and the odor-proof component uses a driving device to provide pre-tightening force to the cover. Since the force applied by the power device to the cover is greater than the gravity of the cover and less than the sum of the gravity of the cover and the weight of the water that can be contained in the drain cylinder, when there is no water flow, the power device can overcome the gravity of the cover and keep the cover automatically blocking the drain outlet upward. When there is water flow in the drain cylinder, the power device cannot keep the cover blocking the drain outlet due to insufficient force, and the water flow rushes open the cover. After the water flow is discharged, the cover still automatically blocks the drain outlet for real-time odor prevention.

[0005] The above-mentioned drain can cooperate with the press-and-pop mechanism to achieve a stable anti-odor effect, but there are still some shortcomings: the cover is sealed with the lower end of the drain cylinder, and the sealing pressure cap seals the upper end of the drain cylinder. When the basin drain is not used for a long time, the inner cavity of the drain cylinder will easily generate negative pressure, which will suck the cover tightly and form adhesion. When it is used again, water flow with normal pressure cannot make the anti-odor plug open normally and affect the drainage effect. In order to solve the above problems, general technicians in this field usually consider: such as opening an air vent at the upper end of the drain cylinder to keep its internal pressure balanced with the outside world, or removing the soft seal between the cover and the drain cylinder to ensure basic anti-odor effect while avoiding adhesion. Summary of the invention

[0006] In view of the above problems existing in the prior art, the present invention provides a deodorizing basin replacement core. The technical problem to be solved by the present invention is that the deodorizing plug of the existing basin drain cannot be opened if it has not been used for a certain period of time, which affects the normal drainage.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] A deodorizing basin replacement core comprises a drain cylinder, a push-and-pop mechanism and a deodorizing umbrella cover that can move up and down, the push-and-pop mechanism comprising a bouncing shell and a moving component that can move up and down relative to the bouncing shell to switch between a high position and a low position, the bouncing shell being positioned in the drain cylinder, the moving component being connected to the bouncing shell, the deodorizing umbrella cover being connected to the lower end of the drain cylinder, the deodorizing umbrella cover always having a tendency to move upward and blocking the lower port of the drain cylinder, and the characterised in that the replacement core also comprises a vertically arranged top rod, the upper end of the top rod being axially fixed to or integrally connected to the moving component, the lower end of the top rod being downwardly opposed to the deodorizing umbrella cover, the moving component located in a low position being able to move downward by a stroke that is greater than the spacing between the lower end of the top rod and the deodorizing umbrella cover.

[0009] The drain tube is used to be inserted into the drain hole of the basin to achieve quick replacement. The push-to-pop mechanism is an existing component, and its moving component can be switched between high and low positions by pressing operation, such as the related bouncing mechanism in the background technology or the press-to-adjust structure on existing ballpoint pens and automatic pens. When it is in a high position, the moving component jumps up to open the upper port of the drain tube to achieve a drainage mode. When it is in a low position, the moving component falls to close the upper port of the drain tube to achieve a water storage mode. The deodorizing umbrella cover can be sealed with the lower port of the drain tube under the reset force of a compression spring or other reset mechanisms to achieve a deodorizing effect. The deodorizing umbrella cover can move downward to open the lower port of the drain tube for drainage after being subjected to the pressure of the water above. By providing a vertically arranged top rod, the upper end of the top rod is connected to the moving component, the lower end of the top rod is opposite to the deodorizing umbrella cover, and the downward movement of the moving component in the low position is greater than the distance between the lower end of the top rod and the deodorizing umbrella cover. In this way, the moving component can cyclically jump between the high position and the low position during the pressing operation. Each time the moving component moves downward, it can drive the top rod to move downward synchronously and can push the deodorizing umbrella cover to open once before reaching the maximum stroke, which can effectively prevent the deodorizing umbrella cover from sticking to the drain pipe port. At the same time, even if the deodorizing umbrella cover is sucked tightly by negative pressure generated in the drain pipe due to long-term non-use, the moving component can be controlled to move downward by pressing and the deodorizing umbrella cover can be forced to be pushed open by the top rod, thereby ensuring normal drainage.

[0010] In the above-mentioned deodorizing basin replacement core, the moving component includes a bouncing member which is columnar and extends upward from the bouncing shell and a bouncing core located in the bouncing shell. The bouncing member is located above the bouncing core, and a vertically arranged return spring is provided between the bouncing core and the bouncing shell below. Each time the bouncing member moves downward, it can push the bouncing core to rotate, and under the action of the return spring, the bouncing core switches and jumps between a high position and a low position in turn. The push rod is axially fixed on the bouncing core and the lower end extends out of the bouncing shell. The bouncing part can make the movable part rotate under the action of the return compression spring through the existing guiding structures such as the inclined surface. When the bouncing inner core rotates to the position constrained by the bouncing shell upward, the bouncing inner core and the bouncing part are both in the low position for water storage mode. When the bouncing inner core rotates to the position where it can move freely up and down, the return compression spring is fully extended. At this time, the movable part and the bouncing part are both in the high position for drainage mode. The top rod is connected to the bouncing inner core, which is conducive to reducing the design length of the top rod, reducing the probability of the top rod being deflected and deformed by force, and ensuring that the deodorizing umbrella cover can be stably pushed open by the top rod.

[0011] As another solution, the moving assembly includes a bouncing member that is columnar and extends upward from the bouncing shell, and a bouncing inner core located in the bouncing shell, the bouncing member is located above the bouncing inner core, a vertically arranged return spring is provided between the bouncing inner core and the bouncing shell below, each time the bouncing member moves downward, it can push the bouncing inner core to rotate, and under the action of the return spring, the bouncing inner core switches and jumps between the low position and the high position in turn, the push rod is axially fixed to the bouncing member, and the lower end of the push rod passes through the bouncing inner core and extends out of the bouncing shell. Similarly, when the push rod is connected to the bouncing member above the bouncing inner core, the bouncing member can more directly transmit the downward pressure exerted by the user's hand on the moving member, reduce the loss of the opening force, and make the opening more convenient and labor-saving.

[0012] In the above-mentioned replacement core of the deodorizing basin, the replacement core also includes a pressing cover, which is screwed to the top of the bouncing part and seals the upper port of the lower water cylinder. The bottom surface of the pressing cover is opposite to the bouncing shell, and the vertical distance between the bottom surface of the pressing cover and the bouncing shell is greater than the distance between the lower end of the push rod and the deodorizing umbrella cover. When operating, the user can directly push the pressing cover downward with a finger to control the action of the pressing and bouncing mechanism. The pressing cover is screwed to the bouncing part, so that the user can easily remove the pressing cover when he needs to maintain the inner wall of the replacement core. In addition, the bottom surface of the pressing cover moves downward to form abutment with the relative bouncing shell, so the distance between the bottom surface of the pressing cover and the lower bouncing shell is set to be greater than the distance between the lower end of the push rod and the deodorizing umbrella cover, which is beneficial to avoid excessive compression of the reset spring due to excessive downward travel of the moving component under the condition that the push rod can push open the deodorizing umbrella cover, thereby ensuring the service life.

[0013] In the above-mentioned deodorizing basin replacement core, the reset spring is sleeved on the periphery of the push rod, so that the reset spring can be guided and restrained by the push rod during the expansion and contraction process, avoiding the reset spring from deflecting and ensuring the working stability of the replacement core.

[0014] In the above-mentioned odor-proof basin replacement core, the lower end of the top rod is vertically opposite to the center of the odor-proof umbrella cover. This is conducive to fully exerting the downward force of the top rod on the odor-proof umbrella cover, ensuring a stable opening effect and avoiding the odor-proof umbrella cover being subjected to an eccentric load due to the downward pressure of the top rod, thereby affecting the sealing effect.

[0015] In the above-mentioned odor-proof basin replacement core, the lower end of the lower water cylinder is fixedly connected to an odor-proof bracket, and the odor-proof umbrella cover has a downwardly arranged guide rod, which is inserted into the odor-proof bracket, and an upper magnet is fixedly arranged in the guide rod, and a lower magnet is fixedly arranged in the odor-proof bracket. The upper magnet is located above the lower magnet, and the magnetic poles of the upper magnet and the lower magnet are distributed up and down and the same poles are arranged opposite to each other. This is conducive to the odor-proof umbrella cover to keep the lower port of the lower water cylinder closed under the repulsive force of the upper magnet and the lower magnet, and the magnet provides repulsive force without direct contact, which is conducive to reducing scratches.

[0016] In the above-mentioned deodorizing basin replacement core, the lower magnet is annular and arranged around the periphery of the guide rod, so that the lower magnet can provide uniform repulsive force to the upper magnet in the guide rod from the circumferential direction, ensuring the stable resetting action of the deodorizing umbrella cover.

[0017] In the above-mentioned deodorizing basin replacement core, a cylindrical hair-blocking net is sleeved on the outer periphery of the bouncing shell, and the outer periphery of the hair-blocking net has a plurality of vertical plate-shaped blades arranged at intervals around the circumference, and the blades are against or slightly spaced from the inner wall of the drain tube. In this way, the hair-blocking net can intercept hair in the water flow during drainage to prevent it from entering the sewer, and the cylindrical hair-blocking net can be easily removed from the bouncing shell, making cleaning and maintenance more convenient.

[0018] In the above-mentioned deodorizing basin replacement core, the hair-blocking net is a soft material. The hair-blocking net can be a soft material such as silicone or rubber. The hair-blocking net has elasticity, which is conducive to the full contact between the blade part and the inner wall of the water cylinder to prevent hair from passing between the two. In addition, when it is removed, it can be deformed by force, which makes it easier and more convenient to disassemble and clean. When it is mounted on the bouncing shell, it can shrink inward to ensure a stable position.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] The replacement core of the odor-proof basin cleverly links the independently acting press-and-pop mechanism and the odor-proof umbrella cover through a top rod, and realizes the forced opening of the odor-proof umbrella cover by external force control of switching drainage and water storage modes. Even if the replacement core has not been used for a long time, it can still maintain stable odor prevention and drainage. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment 1:

[0036] like Figure 3-7As shown, the deodorizing basin replacement core includes a drain pipe 1, a push-and-pop mechanism 2 and a deodorizing umbrella cover 3 that can move up and down. The push-and-pop mechanism 2 includes a bouncing shell 21 and a moving component 22 that can move up and down relative to the bouncing shell 21 to change its position between a high position and a low position. The bouncing shell 21 is positioned in the drain pipe 1, and the moving component 22 is connected to the bouncing shell 21. The deodorizing umbrella cover 3 is connected to the lower end of the drain pipe 1.

When the bouncing inner core 222 rotates to the inner wall limit position against the bouncing shell 21, the bouncing inner core 222 is in a low position, so that the bouncing member 221 is also in a low position for water storage mode, and when the bouncing inner core 222 rotates to a position where it can move freely up and down, the return compression spring 23 is fully extended, and the bouncing inner core 222 and the bouncing member 221 are in a high position for drainage mode. The replacement core also includes a pressing cover 5, which is screwed to the top of the bouncing member 221 and seals the upper port of the lower water cylinder 1. The spacing between the bottom surface of the pressing cover 5 and the relative bouncing shell 21 below is greater than the spacing between the lower end of the top rod 4 and the deodorizing umbrella cover 3. Preferably, the return compression spring 23 is sleeved on the periphery of the top rod 4, and the lower end of the top rod 4 is vertically opposite to the center of the deodorizing umbrella cover 3.

[0037] like Figure 1-5As shown, the lower end of the water cylinder 1 is fixedly connected with an odor-proof bracket 6, and the odor-proof umbrella cover 3 has a guide rod 31 arranged downward, which is inserted into the odor-proof bracket 6. An upper magnet 7 is fixedly arranged in the guide rod 31, and an annular lower magnet 8 is fixedly arranged in the odor-proof bracket 6. The upper magnet 7 is located above the lower magnet 8. The magnetic poles of the upper magnet 7 and the lower magnet 8 are both distributed up and down and arranged with the same poles opposite to each other. The upper part of the lower magnet 8 is annular and arranged around the periphery of the guide rod 31. The outer periphery of the bouncing shell 21 is sleeved with a cylindrical hair-blocking net 9, and the outer periphery of the hair-blocking net 9 has a plurality of vertical plate-shaped blades 91 arranged at intervals around the circumference, and the blades 91 are against the inner wall of the water cylinder 1, and the hair-blocking net 9 is a silicone material.

[0038] Embodiment 2:

[0039] like Figure 8 As shown, this embodiment is basically the same as the first embodiment, except that the top rod 4 is integrally connected to the bouncing member 221 and the lower end thereof passes through the bouncing inner core 222 and extends out of the bouncing shell 21 .

[0040] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
