Description

Technical Field

[0001] The utility model belongs to the field of drainage and relates to a bouncing floor drain. Background Art

[0002] There are many types of floor drains. They can be divided into traditional square floor drains and new-style long-strip floor drains according to their shapes, into side-wall floor drains and floor surface floor drains according to their installation positions, and into direct-drain floor drains and bouncing floor drains according to their operation methods. The bouncing floor drain is usually opened and closed by pressing. For example, a utility model patent with the application date of September 15, 2022, the application number of 2022224499971, and the name of a bouncing water outlet device records a bouncing water outlet device, which includes a bouncing core and a housing with openings at both ends. The bouncing core includes a core body and a bouncing block. The core body is fixed inside the housing, the bouncing block is telescopically connected to the core body, the top end of the bouncing block is connected with a pressing cover, and also includes a conversion cover, which is detachably installed between the bouncing block and the pressing cover, and the conversion cover restricts the downward movement of the bouncing block and the pressing cover. Although the above solution realizes the restriction of the downward movement of the pressing cover and the bouncing block through the setting of the conversion cover, so that the pressing cover is always in the open drainage state. However, combined with the accompanying drawings of its specification, this solution has no filtering function, and there are also improvements in the existing patents for the above problems. For example, a utility model patent with the application date of July 2, 2019, the application number of 2019210235938, and the name of an anti-blocking floor drain records an anti-blocking floor drain, which includes a bouncing core, a cover plate installed at the top end of the bouncing core, and a filtering device movably sleeved at the lower end of the bouncing core. The filtering device includes a filter and a sleeve located in the center of the filter, and the sleeve is sleeved on the bouncing core. The sleeve is installed on the bouncing core by screws, and a guiding groove matched with the screws is arranged on the outer side wall of the bouncing core. The solution of this patent realizes the filtering function through the filter. However, combined with the accompanying drawings of its specification, the filter is installed at the lower end of the bouncing core, that is, inside the water outlet device. This structure cannot filter dirt such as hair and sundries outside, but allows the dirt to enter the water outlet device. When cleaning, the entire water outlet device needs to be taken out, and the operation is very troublesome. In addition, the built-in filtering range is small. When there are many external impurities, the sundries are easily blocked by the filter, which is easy to cause blockage. This is also a problem caused by the built-in filtering.

[0003] To solve the above problems, this application is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a bouncing floor drain aiming at the above problems existing in the prior art. This floor drain has the advantages of convenient filtering and cleaning, and solves the problems of built-in filtering, poor filtering and cleaning of the existing bouncing floor drains.

[0005] The object of the present utility model can be achieved by the following technical solutions: A bouncing floor drain, comprising a housing, a bouncing core and a bouncing cover. The upper end of the bouncing core is connected to the bouncing cover, and the lower end of the bouncing core is connected to the housing. It is characterized in that the upper end of the housing has a sewage inlet, the lower end of the housing has a sewage outlet, the bouncing cover can open or close the sewage inlet, the bouncing cover has a filtering part, and a plurality of filtering holes are opened in the filtering part. When the sewage inlet is open, the filtering part pops up above the sewage inlet, and when the sewage inlet is closed, the filtering part enters the sewage inlet.

[0006] This floor drain can also be called a drainer. The bouncing core is used to realize the up and down bouncing function of the bouncing cover. The specific operation is to press to realize the up and down movement of the bouncing cover. The sewage inlet is for sewage to enter, and the sewage outlet is connected to the sewer for sewage to be discharged. When the sewage inlet is open, it means that the filtering part pops up to expose the filtering holes, and the sewage can enter the housing after being filtered through the filtering holes. When the sewage inlet is closed, it means that the filtering part is inside and the sewage cannot enter the housing, that is, the floor drain is in a closed state. The filtering part of this floor drain is external, that is, the filtering behavior starts when the sewage is discharged. Firstly, it can effectively retain sundries such as hair outside the bouncing cover, which is convenient for cleaning without removing the entire floor drain. Secondly, since the filtering part is in a visible state after popping up, the accumulation of sundries on the filtering part can be clearly observed, which is convenient for judging the cleaning time. Thirdly, compared with the patented scheme in the background technology, the premise of the built-in basket-type filter is that the sundries first enter the floor drain and then are filtered. Due to the relatively small space of the basket because of the internal space structure of the housing, the filtering range is limited and it is easy to cause blockage. The external structure of this scheme has a large filtering range and is not easy to be blocked.

[0007] In the above-mentioned bouncing floor drain, the bouncing cover includes a plug cover, a filtering part and a connecting part. The filtering part extends from under the plug cover, and the connecting part is connected to the upper end of the bouncing core.

[0008] The plug cover is used to close the sewage inlet, and the connecting part realizes the connection between the bouncing cover and the bouncing core.

[0009] In the above-mentioned bouncing floor drain, the connecting part and the bouncing core are screwed.

[0010] The screwed structure can realize the quick rotation and disassembly of the bouncing cover for cleaning.

[0011] In the above-mentioned bouncing floor drain, the plug cover is in the shape of a round cover and the top surface is spherical, the filtering part is in the shape of a circular ring, and the filtering holes are distributed in a circular ring.

[0012] The shapes of the plug cover and the filtering part change according to the overall shape of the floor drain housing. When this floor drain is a long-strip floor drain, the plug cover can be long-strip.

[0013] In the above-mentioned bouncing floor drain, the bottom of the filtering part has an outwardly extending outer extension part in the shape of a circular ring, and a circular-ring-shaped filtering cavity is formed between the outer extension part, the plug cover and the filtering part.

[0014] The existence of the filtering cavity can form a dirt storage cavity, enabling sundries to remain in this chamber with a high probability, preventing the sundries from getting stuck at the edge of the drainage inlet, which may cause the plug cover to be unable to close, and at the same time, accumulating the sundries to prevent them from flushing around with the water flow.

[0015] In the above-mentioned bouncing floor drain, the outer diameter of the outer extension part matches the inner diameter of the drainage inlet.

[0016] The matching of the sizes can minimize the direct entry of sundries into the housing.

[0017] In the above-mentioned bouncing floor drain, the upper end of the housing has a receiving cavity, the top of the receiving cavity is the drainage inlet, the lower end of the housing has a sewage discharge cavity, the bottom end of the receiving cavity is connected to the top end of the sewage discharge cavity, and the bottom end of the sewage discharge cavity is the drainage outlet.

[0018] The receiving cavity provides space for installing the bouncing cover and also enables the entry and ejection of the filtering part. Sewage enters the receiving cavity and the sewage discharge cavity in sequence.

[0019] In the above-mentioned bouncing floor drain, the bouncing cover further includes a cylindrical inner tube, the upper end of the inner tube is connected to the plug cover, the lower end of the inner tube has a water-stop leather, the water-stop leather is axially fixed, and when the drainage inlet is closed, the water-stop leather can seal the top end of the sewage discharge cavity.

[0020] The water-stop leather has a sealing function. When the bouncing cover closes the drainage inlet, the water-stop leather deforms to block the sewage discharge cavity to achieve sealing, which is a prior art and will not be elaborated here.

[0021] In the above-mentioned bouncing floor drain, the bottom end of the sewage discharge cavity has a block-shaped fixing part, the lower end of the bouncing core is fixed on the fixing part, and the fixing part makes the drainage outlet form a continuous shape.

[0022] The fixing part is used for fixing the bouncing core, and the formed continuous-shaped drainage outlet can reduce the resistance when sewage is discharged, improving the sewage discharge efficiency.

[0023] In the above-mentioned bouncing floor drain, the bouncing core includes a fixing seat, a spring, a bouncing shaft and steel balls. The fixing seat is fixed on the fixing part, the spring is located between the fixing seat and the bouncing shaft, the fixing seat has an annular steel ball placement groove, the steel balls are located on the steel ball placement groove, a heart-shaped groove is formed on the outer wall of the bouncing shaft, and the steel balls can move in the heart-shaped groove to realize the card position bouncing of the bouncing shaft.

[0024] The fixed seat and the bouncing shaft are fixed by screws. During the pressing process, different positions of the heart-shaped groove come into contact with the steel ball. The special design of the heart-shaped groove enables the steel ball to be positioned at a special position, thereby realizing the ejection of the bouncing shaft. After the steel ball leaves this position, the bouncing shaft retracts. Details are not elaborated here as it is prior art.

[0025] In the above-mentioned bouncing floor drain, the fixed seat and the fixing part are connected by screwing.

[0026] The screwing structure enables the bouncing core to be rotated and disassembled. Together with the rotational disassembly of the bouncing cover, a two-stage detachable structure is achieved, making the overall floor drain convenient for disassembly and assembly.

[0027] Compared with the prior art, this bouncing floor drain has the following advantages:

[0028] 1. This bouncing floor drain has an external filtering structure design, which has the advantages of being easy to clean and not easily blocked, and the structure design is ingenious.

[0029] 2. The discharge port with a coherent shape in this bouncing floor drain can reduce the resistance when discharging sewage and improve the sewage discharge efficiency.

[0030] 3. This bouncing floor drain has a filter cavity design, which can greatly prevent sundries from getting stuck at the edge of the discharge inlet, resulting in the blocking cover being unable to close, and can accumulate sundries to prevent them from flushing around with the water flow.

[0060] Such as Figures 1 to 6As shown in the figure, this bouncing floor drain includes a housing 1, a bouncing core 2 and a bouncing cover 3. The upper end of the bouncing core 2 is connected to the bouncing cover 3, and the lower end of the bouncing core 2 is connected to the housing 1. The upper end of the housing 1 has a sewage inlet 1a1, and the lower end of the housing 1 has a sewage outlet 1b1. The bouncing cover 3 can open or close the sewage inlet 1a1. The bouncing cover 3 has a filtering part 3b, and a number of filtering holes 3b1 are provided in the filtering part 3b. When the sewage inlet 1a1 is opened, the filtering part 3b pops up above the sewage inlet 1a1. When the sewage inlet 1a1 is closed, the filtering part 3b enters the sewage inlet 1a1. The bouncing core 2 is used to realize the up and down bouncing function of the bouncing cover 3. The specific operation is to press to realize the up and down movement of the bouncing cover 3. The sewage inlet 1a1 is used for sewage to enter, and the sewage outlet 1b1 is connected to the sewer for sewage to be discharged. The opening of the sewage inlet 1a1 means that the filtering part 3b pops up to expose the filtering holes 3b1, and the sewage can enter the housing 1 after being filtered through the filtering holes 3b1. The closing of the sewage inlet 1a1 means that the filtering part 3b is located inside and the sewage cannot enter the housing 1, that is, the floor drain is in a closed state. The filtering part 3b of this floor drain is external, that is, the filtering behavior starts when the sewage discharge starts. First, it can effectively retain sundries such as hair outside the bouncing cover 3, which is convenient for cleaning without removing the entire floor drain. Second, since the filtering part 3b is in an exposed state after popping up, the accumulation of sundries on the filtering part 3b can be clearly observed, which is convenient for judging the cleaning time. Third, compared with the patented solution in the background technology, the premise of the built-in basket type filtering is that the sundries first enter the floor drain and then are filtered. Due to the relatively small basket space due to the internal space structure of the housing 1, the filtering range is limited and it is easy to cause blockage. The external structure of this solution has a large filtering range and is not easy to be blocked.

[0061] The bouncing cover 3 includes a plug cover 3a, a filtering part 3b, and a connecting part 3c. The filtering part 3b extends from under the plug cover 3a, and the connecting part 3c is connected to the upper end of the bouncing core 2. The plug cover 3a is used to close the discharge port 1a1, and the connecting part 3c realizes the connection between the bouncing cover 3 and the bouncing core 2. The connecting part 3c and the bouncing core 2 are screwed together. The screwed connection structure enables the bouncing cover 3 to be quickly rotated and disassembled for cleaning. The plug cover 3a is in the shape of a round cover with a spherical top surface, the filtering part 3b is in the shape of a circular ring, and the filtering holes 3b1 are distributed in a circular ring. When the local drain is a strip-shaped floor drain, the plug cover 3a can be strip-shaped. The bottom of the filtering part 3b has an outward-extending outer extension part 3d in the shape of a circular ring. An annular filtering cavity 3e is formed between the outer extension part 3d, the plug cover 3a, and the filtering part 3b. The existence of the filtering cavity 3e can form a dirt storage cavity, enabling debris to mostly stay in this chamber, preventing the debris from getting stuck at the edge of the discharge port 1a1 and causing the plug cover 3a to be unable to close, and at the same time being able to accumulate debris to prevent it from flushing around with the water flow. The outer diameter of the outer extension part 3d matches the inner diameter of the discharge port 1a1. The size match can minimize the direct entry of debris into the housing 1. The upper end of the housing 1 has a receiving cavity 1a, the top of the receiving cavity 1a is the discharge port 1a1, the lower end of the housing 1 has a sewage discharge cavity 1b, the bottom end of the receiving cavity 1a is connected to the top end of the sewage discharge cavity 1b, and the bottom end of the sewage discharge cavity 1b is the discharge outlet 1b1. The receiving cavity 1a provides space for the installation of the bouncing cover 3 and also enables the entry and ejection of the filtering part 3b. The sewage enters the receiving cavity 1a and the sewage discharge cavity 1b in sequence. The bouncing cover 3 further includes a cylindrical inner cylinder 3f. The upper end of the inner cylinder 3f is connected to the plug cover 3a, and the lower end of the inner cylinder 3f has a water stop skin 3g. The water stop skin 3g is axially fixed. When the discharge port 1a1 is closed, the water stop skin 3g can seal the top of the sewage discharge cavity 1b. The water stop skin 3g has a sealing function. When the bouncing cover 3 closes the discharge port 1a1, the water stop skin 3g deforms to block the sewage discharge cavity 1b to achieve sealing, which is prior art and will not be elaborated.

[0062] The bottom end of the sewage discharge chamber 1b has a block-shaped fixing part 1c, and the lower end of the bouncing core 2 is fixed on the fixing part 1c, and the fixing part 1c makes the discharge port 1b1 form a continuous shape. The fixing part 1c is used to fix the bouncing core 2, and the discharge port 1b1 formed in a continuous shape can reduce the resistance when the sewage is discharged, thereby improving the sewage discharge efficiency. The bouncing core 2 includes a fixing seat 2a, a spring 2b, a bouncing shaft 2c and a steel ball 2d, the fixing seat 2a is fixed to the fixing part 1c, the spring 2b is located between the fixing seat 2a and the bouncing shaft 2c, the fixing seat 2a has an annular steel ball placement groove 2a1, the steel ball 2d is located on the steel ball placement groove 2a1, and a heart-shaped groove 2c1 is provided on the outer wall of the bouncing shaft 2c, and the steel ball 2d can move in the heart-shaped groove 2c1 to realize the bouncing of the bouncing shaft 2c. The fixing seat 2a and the bouncing shaft 2c are fixed by screws. During the pressing process, the heart-shaped groove 2c1 contacts the steel ball 2d at different positions. The special design of the heart-shaped groove 2c1 enables the steel ball 2d to be positioned at a special position, thereby enabling the bouncing shaft 2c to pop out. After the steel ball 2d leaves this position, the bouncing shaft 2c retracts. The details are not described here, and this is the prior art. The fixing seat 2a and the fixing part 1c are screwed. The screwed structure enables the bouncing core 2 to be rotated and disassembled. The rotational disassembly with the bouncing cover 3 realizes a two-stage detachable structure, making the floor drain as a whole easy to disassemble and assemble.
