[0002] In cleanroom environments, strict requirements are placed on air cleanliness. As a crucial component of cleanrooms, the sealing performance of the cleanroom door directly impacts the cleanliness level inside. Existing technology, such as a cleanroom door disclosed in CN219826589U, includes a door frame with a ring structure. The cleanroom door is hinged to the right side of the front wall of the door frame, and a sealing strip is fixedly installed at the connection between the door frame and the cleanroom door. By creating a first groove at the top of the sealing strip, when the cleanroom door approaches the door frame, the outer wall of the door contacts a semi-circular sealing ball, compressing and sliding the semi-circular sealing ball inwards towards the sealing strip. When the cleanroom door is closed, the semi-circular sealing ball, under the action of a spring, is pressed into the arc-shaped groove on the outer wall of the cleanroom door, achieving a dustproof seal.

[0003] However, this existing technology has certain shortcomings. The sealing strip at the bottom of the door frame is not easy to remove and install, and it is prone to wear after prolonged use. Once the sealing strip is worn, the seal between the door and the floor will be reduced, which will affect the air cleanliness inside the cleanroom and make it impossible to effectively meet the high environmental standards required by cleanrooms.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-7 A cleanroom door with a sweeping strip is disclosed, comprising a door body 1 for use in a cleanroom, and a detachable sweeping strip assembly 2 installed at the bottom of the door body 1. The sweeping strip assembly 2 includes a detachable fixing strip 201, a telescopic component 202 installed at the bottom of the fixing strip 201, and a detachable sweeping strip body 203 installed at the bottom of the telescopic component 202. By adopting the above technical solution, a basic structural framework for the cleanroom door is constructed, laying the foundation for subsequent functions such as convenient installation, good sealing, and easy replacement.

[0038] To facilitate the installation of the sweeping strip assembly 2 and the door body 1, in this embodiment: two symmetrically arranged fixing rods 2011 are fixedly connected to the top of the fixing strip 201, and a threaded fixing slot 2012 matching the fixing rod 2011 is provided at the bottom of the door body 1 at the position corresponding to the fixing rod 2011. The top of the fixing strip 201 is inserted into the fixing slot 2012 at the bottom of the door body 1 through the fixing rod 2011. This design makes the installation process simple and quick; the initial installation can be completed simply by inserting the fixing rod 2011 into the corresponding fixing slot 2012, without complicated operations and tools, greatly improving installation efficiency.

[0039] To ensure a stable connection between the telescopic component 202 and the fixed strip 201, and to enable its telescopic function, in this embodiment: the telescopic component 202 includes a connecting strip 2021, and the bottom of the fixed insert 2011 has a connecting groove 2022 that matches the connecting strip 2021, with the connecting strip 2021 slidably disposed on the inner wall of the connecting groove 2022. This sliding connection method allows the connecting strip 2021 to move flexibly within the connecting groove 2022, providing a structural basis for the subsequent tight contact between the sweeping strip body 203 and the ground, while also ensuring the stability of the connection.

[0040] To ensure that the bottom of the sweeping strip body 203 always remains in contact with the ground and to guarantee the seal between the door 1 and the ground, in this embodiment: a plurality of connecting springs 2023 arranged at equal intervals are fixedly connected to the top of the connecting strip 2021, and the other end of the connecting spring 2023 is fixedly connected to the top of the inner wall of the connecting groove 2022. Under the elastic force of the connecting springs 2023, no matter how the door 1 moves during use, the connecting strip 2021 will be subjected to a downward pulling force, thereby driving the sweeping strip body 203 to always be in close contact with the ground, effectively preventing dust and other impurities from entering the cleanroom from the bottom of the door 1, and improving the sealing effect of the cleanroom.

[0041] To prevent dust and other impurities from entering the telescopic assembly 202 and affecting its normal operation and service life, in this embodiment: sealing slides 2024 are provided on both sides of the connecting strip 2021, and sealing grooves 2025 matching the sealing slides 2024 are provided on both sides of the fixing strip 201 at positions corresponding to the sealing slides 2024. When the connecting strip 2021 slides in the connecting groove 2022, the sealing slides 2024 slide synchronously in the sealing groove 2025, forming a sealing barrier that effectively prevents dust from entering the telescopic assembly 202, ensuring the cleanliness and normal operation of the telescopic assembly 202.

[0042] To facilitate the installation and disassembly of the sweeping strip body 203 and the connecting strip 2021, in this embodiment: a T-shaped slide bar 2031 is provided at the top of the sweeping strip body 203, and an installation strip 2032 is fixedly connected to the bottom of the connecting strip 2021. The installation strip 2032 has a T-shaped groove 2033 that matches the T-shaped slide bar 2031, and the sweeping strip body 203 is slidably installed on the inner wall of the T-shaped groove 2033 via the T-shaped slide bar 2031. This matching design of the T-shaped groove and the T-shaped slide bar 2031 makes the installation and disassembly of the sweeping strip body 203 simple and convenient. The operation can be completed simply by sliding the T-shaped slide bar 2031 into or out of the T-shaped groove 2033, without the need for professional tools, thus improving maintenance efficiency.

[0043] To limit the installation of the sweeping strip body 203 and prevent it from shaking or shifting during operation, in this embodiment: a fixing baffle 204 for limiting the T-shaped slide strip 2031 is fixedly connected to one side of the connecting strip 2021 at the position corresponding to the T-shaped slide groove 2033; a fixing component 205 for fixing the T-shaped slide strip 2031 is detachably provided on the other side of the connecting strip 2021 at the position corresponding to the T-shaped slide groove 2033. The fixing baffle 204 can limit one end of the T-shaped slide strip 2031 to prevent it from sliding to one side; while the fixing component 205 can fix the other end of the T-shaped slide strip 2031, ensuring that the sweeping strip body 203 remains stable during operation and will not shift due to vibration or external force, thus ensuring a sealing effect.

[0044] To facilitate the easy fixing and disassembly of the T-shaped slide bar 2031 by the fixing component 205, in this embodiment: the fixing component 205 includes a movable baffle 2051 that matches the T-shaped slide groove 2033, and the movable baffle 2051 is fixedly installed on the side of the connecting bar 2021 by fixing bolts 2052. When it is necessary to fix the sweeping strip body 203, the movable baffle 2051 is placed in a suitable position and fixed to the side of the connecting bar 2021 by fixing bolts 2052, thereby fixing the other end of the T-shaped slide bar 2031; when it is necessary to disassemble the sweeping strip body 203, simply loosen the fixing bolts 2052 and remove the movable baffle 2051. The operation is simple and convenient, improving the ease of maintenance.

[0045] To ensure that the movable baffle 2051 fits more snugly against the connecting strip 2021 during use, in this embodiment, a receiving groove 2053 is provided on the side of the connecting strip 2021 corresponding to the position of the movable baffle 2051. This increases the flatness between the movable baffle 2051 and the connecting strip 2021 during installation, thereby improving the overall aesthetics.

[0046] In use, since the bottom of the door 1 is equipped with a detachable sweeping strip assembly 2, during installation, the fixing rod 2011 at the top of the fixing strip 201 is first inserted into the fixing slot 2012 at the bottom of the door 1 to complete the initial connection between the sweeping strip assembly 2 and the door 1. At this time, the connecting strip 2021 in the telescopic assembly 202 is slidably disposed in the connecting groove 2022 at the bottom of the fixing rod 2011, and under the elastic force of the connecting spring 2023, the connecting strip 2021 is subjected to a downward pulling force. The sweeping strip body 203 is slidably installed in the T-shaped groove 2033 on the bottom mounting strip 2032 of the connecting strip 2021 via the T-shaped slide strip 2031 at its top. The fixed baffle 204 on one side of the connecting strip 2021 limits one end of the T-shaped slide strip 2031, and the movable baffle 2051 on the other side is fixed to the side of the connecting strip 2021 by the fixing bolt 2052, thereby fixing the other end of the T-shaped slide strip 2031, thus realizing the convenient fixing of the sweeping strip body 203.

[0047] During use, the connecting spring 2023 always maintains its elasticity, so that the bottom of the connecting strip 2021 driving the sweeping strip body 203 is always in contact with the ground, ensuring the sealing between the door 1 and the ground.

[0048] When the sweeping strip body 203 is severely worn and cannot be sealed, simply loosen the fixing bolt 2052, remove the movable baffle 2051 and place it in the receiving groove 2053 on the side of the connecting strip 2021, and then slide the T-shaped slide bar 2031 on the top of the sweeping strip body 203 along the T-shaped slide groove 2033 to complete the disassembly of the sweeping strip body 203. When replacing the new sweeping strip body 203, slide the T-shaped slide strip 2031 on top along the T-shaped slide groove 2033, so that one end of the T-shaped slide strip 2031 abuts against the side of the fixed baffle 204. Then, take out the movable baffle 2051 from the receiving groove 2053, cover the movable baffle 2051 and make it abut against the other end of the T-shaped slide strip 2031. Finally, fix the movable baffle 2051 with the fixing bolt 2052. This allows for convenient replacement and fixing of the sweeping strip body 203, ensuring the normal use and sealing effect of the cleanroom door.
