Description

Technical Field

[0001] This invention relates to the field of breathable and soothing devices, and more specifically to a breathable and soothing device for workers in cleanroom environments. Background Technology

[0002] Cleanroom environments are typically used in specialized, standardized workshops for the production of precision products or contamination-sensitive components. Workers are required to wear full-body cleanroom suits for cleanroom operations, and these suits do not allow for ventilation or relief during the work process. Due to the poor breathability and cumbersome nature of full-body cleanroom suits, workers usually only remove them for meals or when they leave work to allow their bodies to breathe and feel comfortable. Wearing cleanroom suits for extended periods can lead to sweating, stuffiness, and discomfort. When workers cannot get timely ventilation and relief, it can affect their work performance and efficiency.

[0003] Therefore, it is necessary to provide a breathable and soothing device for workers in cleanroom environments to solve the problems mentioned in the background art. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a breathable and comfortable device for workers in cleanroom environments, comprising:

[0005] A fixed frame has a height adjustment device fixed vertically downward at the lower end of its horizontally extended upper section. A dust collection device is suspended at the lower end of the height adjustment device. An inlet is opened at the lower end of the dust collection device. The height position of the dust collection device can be adjusted by controlling the height adjustment device.

[0006] The upper limit ring is provided in two sets, which are respectively hung on both sides of the dust collection device;

[0007] A lower limit ring, correspondingly hung below the upper limit ring, and an air inlet mechanism is provided on the lower limit ring; and

[0008] An exhaust pipe is located on both sides of the dust collection device, and a deep purification device is installed on the exhaust pipe.

[0009] As a preferred embodiment of the present invention, both the upper limit ring and the lower limit ring include: a limit ring body, on which a plurality of air bladders are uniformly adhered, and a pressure sensing unit is provided inside the air bladders; a ring seat is fixed on one outer circumferential surface of the limit ring body; the ring seat is hung on the outside of the dust collection device; an air inlet hose is connected to the side of the ring seat; one end of the air inlet hose is connected to the air bladders; and the other end of the air inlet hose is connected to an air pump.

[0010] As a preferred embodiment of the present invention, the air intake mechanism includes: a connecting hose that is connected to the air intake hose of the lower limiting ring, a limiting cylinder that is made of rigid material is sleeved on the outside of the connecting hose, and a flexible strip that is connected to the end of the connecting hose. The flexible strip has a plurality of air outlet holes that are evenly opened on it and are connected to the connecting hose.

[0011] As a preferred embodiment of the present invention, a temperature control device is connected upstream of the air intake hose, and the temperature control device is capable of regulating the temperature of the gas filled into the airbag and discharged from the air intake mechanism.

[0012] As a preferred technical solution of the present invention, the limiting ring body includes: an inner ring cylinder and an outer ring cylinder. The outer ring cylinder is coaxially disposed outside the inner ring cylinder, and the two are fixedly connected by a connecting rod. Side ring plates are provided on both sides of the inner ring cylinder and the outer ring cylinder. Each side ring plate is elastically connected by multiple tension springs. A limiting chamfer is provided on the side of the side ring plate near the center, which can form a limiting groove with a figure-eight structure on both sides of the airbag.

[0013] As a preferred embodiment of the present invention, the dust collection device includes:

[0014] The box body is suspended from the lower end of the height adjustment device. The upper end of the box body has strip-shaped slots on both sides. The inside of the box body is made of transparent material facing the face. A telescopic rod is vertically fixed in the middle of the top of the box body. Multiple arc-shaped strips are evenly fixed on the lower outer circumference of the telescopic rod. The inner arc surface of the arc-shaped strips is set downward. A sealing cylinder is coaxially set on the outer side of the telescopic rod. The end of the arc-shaped strip away from the telescopic rod is fixedly connected to the lower inner side of the sealing cylinder.

[0015] A limiting square tube is fixedly installed inside the top of the housing. A limiting circular hole is formed at the lower end of the limiting square tube, which is adapted to the sealing cylinder. Dust collection channels are formed between the two sides of the limiting square tube and the inner wall of the housing.

[0016] A dust collection mechanism is inserted into the socket and located inside the dust collection channel.

[0019] Compared with the prior art, the present invention provides a breathable and comfortable device for workers in cleanroom environments, which has the following beneficial effects:

[0020] In this invention, upper and lower limit rings are used to limit the cuffs and trouser legs of the one-piece cleanroom suit, creating a relatively sealed channel between the cleanroom suit and the human body surface, with only the face as the exit. Then, an air inlet mechanism is set up to introduce air into the lower part of the worker's legs, allowing the worker's body surface to breathe and feel comfortable without removing the cleanroom suit. A dust collection device is set up so that the worker's head can be inserted into the chamber to collect the dust blown out from inside the cleanroom suit. The dust in the air is then collected again by a dust collection plate and a deep purification device to prevent dust from spreading into the cleanroom environment and affecting the cleanliness of the cleanroom environment and the processing quality of the products.

[0021] Furthermore, the two side plates of the limiting ring are set to be elastically connected. When the airbag is inflated, the two sides of the airbag are elastically limited so that the direction of its expansion is approximately the same. This avoids uneven force on each airbag during inflation, resulting in inconsistent expansion size and shape, and air leakage at the cuff or trouser leg opening. Attached Figure Description

[0028] Please see Figure 1-5 This invention provides a breathable and comfortable device for workers in cleanroom environments, comprising:

[0029] A fixed frame 1 has a height adjustment device 2 fixed vertically downward at the lower end of its horizontally extended upper section. A dust collection device 3 is suspended at the lower end of the height adjustment device 2. An inlet 32 ​​is opened at the lower end of the dust collection device 3. The height position of the dust collection device 3 can be adjusted by controlling the height adjustment device 2.

[0030] The upper limit ring 4 is provided in two sets, which are respectively hung on both sides of the dust collection device 3;

[0031] A lower limit ring 5 is correspondingly hung below the upper limit ring 4, and an air inlet mechanism 55 is provided on the lower limit ring 5; and

[0032] The exhaust pipe 6 is located on both sides of the dust collection device 3, and a deep purification device 61 is provided on the exhaust pipe 6.

[0033] It needs to be explained that by controlling the height adjustment device 2, the height of the dust collection device 3 is adjusted to adapt to the height of the human body, thereby reserving standing space for the human body below the dust collection device 3. When the worker needs to breathe and relax due to long-term work, the upper limit ring 4 and the lower limit ring 5 are put on the wrists and ankles to limit the cuffs and trousers of the one-piece cleanroom suit, so as to form a relatively sealed channel between the cleanroom suit and the human body surface, with only the face as the exit. Then, the head is inserted into the dust collection device 3 through the inlet 32, and the air inlet mechanism 55 blows air into the trousers to breathe and relax the worker's body surface. The blown dust is collected in the dust collection device 3 to prevent the worker's own dust from overflowing when breathing and relaxing, thus ensuring the cleanliness of the cleanroom environment.

[0034] In this embodiment, both the upper limit ring 4 and the lower limit ring 5 include: a limit ring body 51, on which multiple airbags 52 are evenly adhered; a pressure sensing unit is disposed within each airbag 52; a ring seat 53 is fixed to one outer circumferential surface of the limit ring body 51; the ring seat 53 is hung on the outside of the dust collection device 3; an air inlet hose 54 is connected to the side of the ring seat 53; one end of the air inlet hose 54 is connected to the airbag 52; and the other end of the air inlet hose 54 is connected to an air pump. The airbag 52 is inflated by the air pump until it expands to the preset pressure value of the pressure sensing unit, and then the inflation stops, thus completing the limitation of the cuffs and trouser cuffs of the coverall cleanroom suit.

[0035] In this embodiment, the air intake mechanism 55 includes: a connecting hose 551, which is connected to the air intake hose 54 of the lower limiting ring 5; a limiting cylinder 552 is sleeved on the outside of the connecting hose 551; the limiting cylinder 552 is made of rigid material; and a flexible strip 553 is connected to the end of the connecting hose 551. The flexible strip 553 has a plurality of air outlet holes evenly opened on it, and the air outlet holes are connected to the connecting hose 551.

[0036] It should be explained that when the worker uses the lower limit ring 5 for limiting, the flexible strip 553 and the limiting cylinder 552 need to be inserted into the trouser leg of the cleanroom suit, and then the limiting ring body 51 is put on the outside of the limiting cylinder 552 and the trouser leg of the cleanroom suit to prevent the airbag 52 from squeezing the connecting hose 551 after inflation, changing the air intake cross section and affecting its air intake rate. In addition, the flexible strip 553 can be bent according to the worker's wishes to adapt to the cross section of the worker's legs and increase its air outlet area.

[0037] In this embodiment, a temperature control device is connected upstream of the air intake hose 54. The temperature control device can regulate the temperature of the gas filled into the airbag 52 and discharged from the air intake mechanism 55.

[0038] In other words, by adjusting the output temperature of the temperature control device, the temperature of the gas inflated into the airbag 52 and the gas introduced into the cleanroom garment can be regulated. When the worker feels cold or hot, the temperature of the temperature control device can be raised or lowered accordingly to meet the needs of breathable comfort while warming or cooling the worker.

[0039] In this embodiment, the limiting ring 51 includes an inner ring cylinder 511 and an outer ring cylinder 512. The outer ring cylinder 512 is coaxially disposed outside the inner ring cylinder 511, and the two are fixedly connected by a connecting rod 513. Side ring plates 514 are provided on both sides of the inner ring cylinder 511 and the outer ring cylinder 512. Each side ring plate 514 is elastically connected by a plurality of tension springs 515. A limiting chamfer is provided on the side of the side ring plate 514 near the center, which can form a limiting groove with a figure-eight structure on both sides of the airbag 52.

[0040] It should be explained that when the airbag 52 is inflated and limited, the side ring plates 514 elastically set on both sides of the airbag 52 can elastically limit the two sides of the airbag 52, so that the direction of its expansion and extension is approximately the same. This avoids uneven force on each airbag 52 when it is inflated, which would cause the airbags 52 to expand in different sizes and shapes, resulting in air leakage at the cuffs or trouser legs, which would cause dust to spread into the cleanroom environment.

[0041] In this embodiment, the dust collection device 3 includes:

[0042] The box body 31 is suspended at the lower end of the height adjustment device 2. The upper end of the box body 31 has strip-shaped slots on both sides. The inside of the box body 31 is made of transparent material facing the face. A telescopic rod 34 is vertically fixed in the middle of the top of the box body 31. Multiple arc-shaped strips 36 are evenly fixed on the lower outer circumference of the telescopic rod 34. The inner arc surface of the arc-shaped strips 36 is set downward. A sealing cylinder 35 is coaxially arranged on the outer side of the telescopic rod 34. The end of the arc-shaped strip 36 away from the telescopic rod 34 is fixedly connected to the lower inner side of the sealing cylinder 35.

[0043] A limiting square tube 37 is fixedly disposed inside the top of the housing 31. A limiting circular hole is formed at the lower end of the limiting square tube 37, which is adapted to the sealing cylinder 35. Dust collection channels are formed between the two sides of the limiting square tube 37 and the inner wall of the housing 31.

[0044] The dust collection mechanism 33 is inserted into the socket and located inside the dust collection channel.

[0045] It should be explained that the use of transparent materials increases the brightness inside the box 31, preventing discomfort caused to workers by the dark space. The curved strip 36, with its inverted bowl-shaped structure at the worker's head, prevents blown dust from falling onto the head and being carried away.

[0046] In the initial state, the telescopic rod 34 is at its extension limit under the influence of the gravity of the sealing cylinder 35. At this time, the sealing cylinder 35 coincides with the inlet 32, separating the internal environment of the box 31 from the external environment. When the worker needs to breathe and relax, he uses his head to lift the arc-shaped strip 36 to move the sealing cylinder 35 upward, releasing the seal of the sealing cylinder 35, allowing the worker's head to enter the box 31 for breathing and relaxation. The dust collection mechanism 33 collects most of the dust blown from the side of the worker's face, and then the deep purification device 61 performs deep treatment on the air that has passed through the dust collection mechanism 33, and then discharges it through the exhaust pipe 6. The secondary dust collection ensures the quality of the discharged air and avoids affecting the cleanliness of the dust-free environment.

[0047] In this embodiment, the dust collection mechanism 33 includes an insert plate 331, which is inserted into the socket. Multiple dust collection plates 332 are vertically spaced at the lower end of the insert plate 331. The dust collection plates 332 are arranged parallel to the side wall where the air outlet pipe 6 is located. Multiple escaping holes are evenly opened on the dust collection plates 332. The size of the escaping holes gradually decreases and the density gradually increases from the side of the sealing cylinder 35 to the side wall of the box 31.

[0048] It should be explained that the dust collection plate 332 is an electrostatic plate, which adsorbs and collects free dust in the air. It is equipped with multiple vent holes of different sizes and densities to divert the air carrying dust multiple times, changing the size of the flow channel through which the free dust flows, thereby improving the dust collection effect. After collecting for a certain period of time or using it a certain number of times, the dust collection plate 332 is cleaned and replaced.

[0049] In this embodiment, a plurality of gas nozzles 38 are evenly spaced along the circumference of the upper end of the inlet 32, and each gas nozzle 38 is inclined toward the dust collection plates 332 on both sides.

[0050] When the worker takes a breather to relax, the gas nozzle 38 is activated to blow air, creating a negative pressure outside the worker's face outlet, which drives the air blown out from inside the cleanroom suit to the dust collection plate 332, improving dust collection efficiency.

[0051] In practice, the worker places the upper and lower limit rings on their wrists and ankles respectively, and inserts the air intake mechanism inside the trouser legs of the coverall cleanroom suit. Then, the airbags of the upper and lower limit rings are inflated to limit the cuffs and trouser legs. After that, the loop elastic cord is placed around the neck of the cleanroom suit, and the head is inserted into the chamber. Then, the air pump is activated to drive the air intake mechanism to ventilate the trouser legs, providing ventilation and comfort for the worker and avoiding the problem of not being able to breathe and relieve stress when working in a cleanroom environment for a long time.

[0052] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
