Abstract
Description
Technical Field
[0001] This utility model relates to the field of air shower technology, specifically an air shower for three-sided air blowing in a cleanroom. Background Technology
[0002] An air shower is a localized air purification device widely used in cleanrooms, primarily for the transition between clean and non-clean areas. When personnel need to enter a clean area from a non-clean area, they must first pass through an air shower. During this process, the air shower releases high-speed clean air. This airflow effectively removes dust and particulate matter from the human body surface, thereby reducing or preventing contaminants from being brought into the clean environment and ensuring the air quality of the cleanroom.
[0003] Extensive searches revealed that CN220346708U discloses an air shower, comprising an air shower body, an air blowing assembly on the inner wall of the air shower body, a rotating motor fixedly connected to the bottom outer wall of the air shower body, a rotating disk fixedly connected to the output shaft of the rotating motor, and a collection mechanism on the bottom of one side outer wall of the air shower body.
[0004] In existing technologies, air showers use a fan to blow air from outside the shower body through a filter screen into a cavity. The air is then dispersed within the cavity and blown out through the nozzles, allowing for air showering of users. However, in practice, due to the single air source, the airflow from the nozzles, which are far from the air source, is relatively weak. Furthermore, during air showering, dust from the user's body is stirred up within the shower chamber by the airflow. The existing dust discharge ports are located in a single location, making it difficult to quickly collect the stirred-up dust, resulting in low efficiency during air showering. Therefore, a three-sided air shower for cleanrooms is needed to solve these problems. Utility Model Content
[0005] The purpose of this invention is to provide an air shower for cleanrooms with three-sided airflow, which has the advantages of efficient dust removal, uniform airflow distribution and rapid collection of dust, and solves the problems of insufficient airflow and low dust removal efficiency caused by a single air source in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an air shower chamber for three-sided air blowing in a cleanroom, comprising a base, an air chamber fixedly installed on the upper surface of the base, the air chamber comprising an air shower compartment and a dust collection compartment, the front and rear ends and the bottom of the air shower compartment adopt an open structure design, an inner lining plate fixedly installed on the inner side of the air shower compartment, an air duct provided between the air shower compartment and the inner lining plate, and an air inlet slot provided on the inner lining plate;
[0007] The dust collection chamber includes a bottom chamber and a vertical chamber. The rear end of the bottom chamber is connected to the vertical chamber and installed. The bottom chamber is embedded in the bottom of the air shower chamber. A first dust discharge trough is opened on the upper surface of the bottom chamber, and a second dust discharge trough is opened on the front of the vertical chamber.
[0008] Preferably, a door frame is fixedly installed on the front end of the upper end of the base, the back of the door frame is fixedly connected to the front of the air shower chamber, and a sealing door is rotatably installed on the inner side of the door frame. This design, through the fixed connection between the door frame and the air shower chamber, ensures the structural stability and sealing of the air shower, preventing the intrusion of external pollutants and improving the purification efficiency of the air shower. The sealing door self-closes with the door frame via a self-closing component. This design simplifies the operation process, reduces the risk of cleanroom contamination due to human factors, and improves the convenience and safety of using the air shower.
[0009] Preferably, a self-closing component is fixedly installed on the top front of the sealed door, and the sealed door automatically closes with the door frame through the self-closing component. The application of the self-closing component in the design ensures that the sealed door can automatically close after personnel pass through without additional operation. This not only improves the automation level of the air shower, but also reduces clean area contamination caused by forgetting to close the door.
[0010] Preferably, the air shower chamber has openings on its top and sides, and five axial fans are embedded therein. All five axial fans output airflow to one side of the inner lining plate. This five-fan layout on the top and sides of the air shower chamber provides omnidirectional airflow to the user. This three-sided airflow design improves air shower efficiency and ensures more thorough dust removal. Because the axial fans are evenly distributed on the top and sides of the air shower chamber, the airflow is more uniform, avoiding differences in dust removal effect caused by uneven airflow and improving the overall performance of the air shower chamber.
[0011] Preferably, the air inlet slots are longitudinally equidistantly distributed on the inner lining plate, with the bottom of the inner side of the air inlet slots flush with the top of the bottom chamber. This longitudinal equidistant distribution of the air inlet slots on the inner lining plate ensures that the airflow is evenly distributed into the air shower chamber. This design contributes to a more uniform air shower effect and improves the dust removal efficiency of the air shower. The flush design of the bottom of the inner side of the air inlet slots with the top of the bottom chamber ensures the continuity of airflow and effective dust collection, avoiding waste of airflow and dust dispersion.
[0012] Preferably, the bottom back of the vertical compartment has an opening and a dust-collecting sponge is embedded therein. A mounting bracket is fixedly installed at the bottom back of the vertical compartment, and a grid plate is movably inserted into the back of the vertical compartment via the mounting bracket. The design of the dust-collecting sponge and grid plate at the bottom back of the vertical compartment provides a highly efficient dust collection and filtration system. This design helps to quickly collect dust raised during the air shower process, maintaining the cleanliness of the air shower room. The movable installation of the grid plate on the back of the vertical compartment via the mounting bracket makes the maintenance and cleaning of the dust collection system more convenient, improving the maintenance efficiency and service life of the air shower room.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This invention achieves three-sided airflow by installing five axial fans on the top and sides of the air shower chamber. This design improves air shower efficiency and ensures a more thorough dust removal effect.

An inner lining plate is fixedly installed inside the air shower chamber, and air inlet slots are formed on the inner lining plate. These air inlet slots are evenly distributed longitudinally on the inner lining plate, allowing the airflow to be evenly directed into the air shower chamber. This design helps to achieve a more uniform air shower effect and improves the dust removal efficiency of the air shower chamber.
[0015] The dust collection chamber consists of a base chamber and a vertical chamber. The top surface of the base chamber has a first row of dust troughs, and the front of the vertical chamber has a second row of dust troughs. This design helps to quickly collect dust generated during the air shower process, maintaining the cleanliness of the air shower room. A dust-collecting sponge is embedded at the bottom rear of the vertical chamber, further collecting and filtering dust. This design also helps to quickly collect dust generated during the air shower process, maintaining the cleanliness of the air shower room. A grid plate is movably inserted into the rear of the vertical chamber via a mounting bracket. This design makes the maintenance and cleaning of the dust collection system more convenient, improving the maintenance efficiency and service life of the air shower room.

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.
[0024] Example
[0025] like Figures 1 to 5 As shown, one embodiment of this utility model is provided: an air shower for three-sided air blowing in a cleanroom, including a base 1, an air chamber 2 fixedly installed on the upper surface of the base 1, the air chamber 2 including an air shower chamber 21 and a dust collection chamber 22, the front and rear ends and the bottom of the air shower chamber 21 are all designed with an open structure, an inner lining plate 24 is fixedly installed on the inner side of the air shower chamber 21, an air duct is provided between the air shower chamber 21 and the inner lining plate 24, and an air inlet slot 241 is opened on the inner lining plate 24;
[0026] The dust collection chamber 22 includes a bottom chamber 221 and a vertical chamber 222. The rear end of the bottom chamber 221 is connected to the vertical chamber 222 and installed. The bottom chamber 221 is embedded in the bottom of the air shower chamber 21. A first dust trough 2211 is opened on the upper surface of the bottom chamber 221, and a second dust trough 2221 is opened on the front of the vertical chamber 222.
[0027] Specifically, by installing five axial fans 23 on the top and sides of the air shower chamber 21, three-sided airflow is achieved. This design improves air shower efficiency and ensures a more thorough dust removal effect. Since the axial fans 23 are evenly distributed on the top and sides of the air shower chamber 21, the airflow output is more uniform, avoiding differences in dust removal effect caused by uneven airflow and improving the overall performance of the air shower chamber. An inner lining plate 24 is fixedly installed inside the air shower chamber, and air inlet slots 241 are formed on the inner lining plate 24. These air inlet slots 241 are longitudinally and equidistantly distributed on the inner lining plate 24, allowing the airflow to be evenly directed into the air shower chamber 21. This design helps to achieve a more uniform air shower effect and improves the dust removal efficiency of the air shower chamber.
[0028] The dust collection chamber 22 includes a bottom chamber 221 and a vertical chamber 222. The top surface of the bottom chamber 221 has a first dust trough 2211, and the front of the vertical chamber 222 has a second dust trough 2221. This design helps to quickly collect dust generated during the air shower process, maintaining the cleanliness of the air shower chamber. A dust-collecting sponge 25 is embedded in the bottom rear of the vertical chamber 222. The dust-collecting sponge 25 further collects and filters dust, helping to quickly collect dust generated during the air shower process and maintaining the cleanliness of the air shower chamber. A grid plate 26 is movably inserted into the back of the vertical chamber 222 via an insert bracket 27. This design makes the maintenance and cleaning of the dust collection system more convenient, improving the maintenance efficiency and service life of the air shower chamber.
[0029] In summary, the design of this air shower effectively solves the problems in the existing technology by using three-sided airflow, evenly distributed air output, and a high-efficiency dust collection system, thereby improving the dust removal and ash discharge efficiency of the air shower.
[0030] Furthermore, a door frame 12 is fixedly installed on the front end of the upper part of the base 1. The back of the door frame 12 is fixedly connected to the front of the air shower chamber 21, and a sealing door 11 is rotatably installed on the inner side of the door frame 12. The fixed connection between the door frame 12 and the air shower chamber 21 ensures the structural stability and sealing of the air shower chamber, prevents the intrusion of external pollutants, and improves the purification efficiency of the air shower chamber. The sealing door 11 self-closes with the door frame 12 through the self-closing component 13. This design simplifies the operation process, reduces the risk of cleanroom contamination caused by human factors, and improves the convenience and safety of using the air shower chamber.
[0031] Furthermore, a self-closing assembly 13 is fixedly installed on the top front of the sealed door 11, and the sealed door 11 closes automatically with the door frame 12 through the self-closing assembly 13. The application of the self-closing assembly 13 in the design ensures that the sealed door 11 can automatically close after personnel pass through without additional operation. This not only improves the automation level of the air shower, but also reduces clean area contamination caused by forgetting to close the door.
[0032] Furthermore, five axial fans 23 are embedded in the top and sides of the air shower chamber 21, with each fan outputting airflow to one side of the inner lining plate 24. This arrangement of five axial fans 23 on the top and sides of the air shower chamber 21 provides omnidirectional airflow to the user. This three-sided airflow design improves air shower efficiency and ensures more thorough dust removal. Because the axial fans 23 are evenly distributed on the top and sides of the air shower chamber 21, the airflow is more uniform, avoiding differences in dust removal efficiency caused by uneven airflow and improving the overall performance of the air shower.
[0033] Furthermore, the air inlet slots 241 are longitudinally equidistantly distributed on the inner lining plate 24, with the bottom of the inner side of the air inlet slots 241 flush with the top of the bottom chamber 221. This longitudinal equidistant distribution of the air inlet slots 241 on the inner lining plate 24 ensures that the airflow is evenly directed into the air shower chamber 21. This design helps achieve a more uniform air shower effect and improves the dust removal efficiency of the air shower chamber. The flush design of the bottom of the inner side of the air inlet slots 241 with the top of the bottom chamber 221 ensures the continuity of airflow and effective dust collection, avoiding waste of airflow and dust dispersion.
[0034] Furthermore, a dust-collecting sponge 25 is embedded and installed at the bottom rear opening of the vertical chamber 222. An insert bracket 27 is fixedly installed at the bottom rear of the vertical chamber 222, and a grid plate 26 is movably inserted into the back of the vertical chamber 222 via the insert bracket 27. The design of the dust-collecting sponge 25 and grid plate 26 at the bottom rear of the vertical chamber 222 provides a highly efficient dust collection and filtration system. This design helps to quickly collect dust raised during the air shower process, maintaining the cleanliness of the air shower chamber. The movable insertion of the grid plate 26 into the back of the vertical chamber 222 via the insert bracket 27 makes the maintenance and cleaning of the dust collection system more convenient, improving the maintenance efficiency and service life of the air shower chamber.
[0035] In use, the user stands outside the air shower chamber, facing the door frame 12 and the sealed door 11. The user manually opens the sealed door 11, enters the air shower chamber 21, and stands inside, ensuring the sealed door 11 is closed to maintain a clean environment. The operation control system activates the five axial fans 23 on the top and sides of the air shower chamber 21, which output airflow to one side of the inner lining plate 24. The clean air blown out by the axial fans 23 enters the air shower chamber 21 through the air inlet slots 241 on the inner lining plate 24, achieving three-sided airflow and effectively removing dust from the user's body. During the air shower process, dust is blown into the first dust trough 2211 of the bottom chamber 221 and the second dust trough 2221 of the vertical chamber 222. After initial separation, dust falls into the dust collection sponge 25 at the bottom of the back of the vertical chamber 222 for further collection and filtration. After the air shower process is completed, the user opens the sealed door 11 and leaves the air shower chamber. Regularly inspect and clean the dust collection sponge 25 and the grid plate 26 to ensure that the dust removal system of the air shower is unobstructed and maintains efficient operation.
