Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning clothing, and in particular relates to a cuff sealing structure of air-conditioning clothing. Background Art

[0002] In air-conditioning clothing using TEC (thermoelectric cooling) technology, the collar, cuffs and lower opening of the clothing are tightened by tightening devices, so that the clothing body and the human body form a closed space, and then the air is circulated internally through the duct fan. This design can circulate the cold energy generated by the semiconductor refrigeration sheet internally, thereby achieving the purpose of improving comfort.

[0003] In order to maintain the stability of the internal temperature of the air-conditioning clothing and improve the cooling effect, the sealing performance of the cuffs as the opening of the clothing is particularly important. However, the existing sealing structure of the cuffs of air-conditioning clothing often has problems such as insufficient sealing performance and inconvenient operation. Therefore, it is necessary to improve the sealing structure of the cuffs of air-conditioning clothing. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a sealing structure for the cuff of an air-conditioning suit, so as to solve the problems that the existing sealing structure for the cuff of an air-conditioning suit often has insufficient sealing performance and inconvenient operation.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a sealing structure for the cuffs of an air-conditioning suit, comprising an air-conditioning suit body, a sealing mechanism being arranged on the inner side of the cuffs of the air-conditioning suit body, the sealing mechanism comprising an elastic band, the front end of the elastic band being sewn to the air-conditioning suit body, the rear end of the elastic band being connected to an airbag, an inflation chamber being arranged inside the airbag, the rear end of the airbag being sewn to the air-conditioning suit body, a control mechanism being installed on the outer side of the cuffs of the air-conditioning suit body, the control mechanism comprising an outer shell, an air pump, a two-position three-way solenoid valve, a power module and a controller being installed in the outer shell, the air outlet of the air pump being connected to one end port of the two-position three-way solenoid valve, and the other end port of the two-position three-way solenoid valve being connected to the inflation chamber.

[0006] The beneficial effects of the utility model are as follows: the air pump can inflate the inflation cavity through the two-position three-way solenoid valve, so that the inflation cavity is inflated and expanded to effectively seal the cuffs of the air-conditioning suit body; after the valve path of the two-position three-way solenoid valve is automatically switched, the elastic belt can pull the airbag to quickly discharge the air in the inflation cavity, making it convenient for people to wear the sealing mechanism and the air-conditioning suit body.

[0007] In order to effectively ensure the sealing effect of the airbag after inflation;

[0008] As a further improvement of the above technical solution: the inflation cavity is an annular chamber structure.

[0009] The beneficial effect of this improvement is that the airbag surrounds the suit on the outside of the wearer's wrist, and after the inflation cavity is filled with gas, the gap between the air-conditioning suit body and the wearer's wrist is effectively closed, thereby ensuring the sealing effect at the cuff of the air-conditioning suit body.

[0010] In order to facilitate the personnel's hands to penetrate into the sealing mechanism;

[0011] As a further improvement of the above technical solution: the elastic band is a cylindrical structure.

[0012] The beneficial effect of this improvement is that the elastic band can pull the airbag in the exhaust state, accelerate the discharge of gas in the inflation cavity, and enable the airbag to be attached to the air-conditioning suit body, making it convenient for the person's hand to penetrate into the sealing mechanism.

[0013] In order to inflate the inflation cavity to a suitable volume so as to effectively seal the cuff of the air-conditioning suit body with appropriate pressure;

[0015] The beneficial effect of this improvement is that after the airbag is inflated, the pressure received by the thin film pressure sensor sandwiched between the inflation chamber and the air-conditioning suit body changes. When the pressure value fed back by the thin film pressure sensor exceeds the set threshold range, the controller controls the air pump to automatically stop, so that the airbag can seal the cuff of the air-conditioning suit body with a suitable volume and pressure.

[0016] In order to achieve effective exhaust and inflation;

[0017] As a further improvement of the above technical solution: the two valve circuit states of the two-position three-way solenoid valve are that the air pump is connected to the inflation chamber, and the inflation chamber is connected to the outer shell, and the controller is electrically connected to the two-position three-way solenoid valve.

[0018] The beneficial effect of this improvement is that the controller can control the change of the valve path of the two-position three-way solenoid valve, thereby changing the gas flow direction, thereby achieving effective exhaust and inflation.

[0019] In order to keep the outer shell in effective communication with the outside air;

[0020] As a further improvement of the above technical solution: an air intake grille is provided on the outer shell.

[0021] The beneficial effect of this improvement is that the provision of the air intake grille enables the air pump to stably draw in external air and enables the inflation chamber to effectively discharge air.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0029] Embodiment 1:

[0030] like Figure 1—4 shows: a cuff sealing structure of an air-conditioning suit, comprising an air-conditioning suit body 1, a sealing mechanism 4 is arranged on the inner side of the cuff of the air-conditioning suit body 1, the sealing mechanism 4 comprises an elastic band 41, the front end of the elastic band 41 is sewn to the air-conditioning suit body 1, the rear end of the elastic band 41 is connected to an air bag 42, an inflation chamber 43 is arranged inside the air bag 42, the rear end of the air bag 42 is sewn to the air-conditioning suit body 1, a control mechanism 3 is installed on the outer side of the cuff of the air-conditioning suit body 1, the control mechanism 3 comprises an outer shell 31, an air pump 33, a two-position three-way solenoid valve 34, a power module 35 and a controller 36 are installed in the outer shell 31, the air outlet of the air pump 33 is connected to a two-position three-way solenoid valve 34, a power module 35 and a controller 36 One end port of the two-position three-way solenoid valve 34 is connected to the inflation chamber 43, and the other end port of the two-position three-way solenoid valve 34 is connected to the inflation chamber 43. The air pump 33 can inflate the inflation chamber 43 through the two-position three-way solenoid valve 34, so that the inflation chamber 43 is inflated and expanded to effectively seal the cuff of the air-conditioning suit body 1; after the valve path of the two-position three-way solenoid valve 34 is automatically switched, the elastic band 41 can pull the airbag 42 to quickly discharge the air in the inflation chamber 43, so that it is convenient for people to wear the sealing mechanism 4 and the air-conditioning suit body 1. The inflation chamber 43 is an annular chamber structure, and the airbag 42 surrounds the outside of the wearer's wrist. After the inflation chamber 43 is filled with gas, the gap between the air-conditioning suit body 1 and the wearer's wrist is effectively sealed, thereby ensuring that the air-conditioning suit The elastic band 41 is a cylindrical structure, which can pull the airbag 42 in the exhaust state, accelerate the discharge of gas in the inflation cavity 43, so that the airbag 42 can be close to the air-conditioning suit body 1, and facilitate the personnel's hand to penetrate the sealing mechanism 4. A film pressure sensor 37 is arranged between the airbag 42 and the air-conditioning suit body 1. The film pressure sensor 37 is electrically connected to the controller 36. The controller 36 includes a control switch, a single-chip microcomputer and a relay. After the airbag 42 is inflated, the pressure received by the film pressure sensor 37 sandwiched between the inflation cavity 43 and the air-conditioning suit body 1 changes. When the pressure value fed back by the film pressure sensor 37 exceeds the set threshold When the pressure is within the value range, the controller 36 controls the air pump 33 to automatically stop, so that the airbag 42 seals the cuff of the air-conditioning suit body 1 with a suitable volume and pressure. The two valve circuit states of the two-position three-way solenoid valve 34 are that the air pump 33 is connected to the inflation chamber 43, and the inflation chamber 43 is connected to the outer shell 31. The controller 36 is electrically connected to the two-position three-way solenoid valve 34. The controller 36 can control the change of the valve circuit of the two-position three-way solenoid valve 34, so as to change the gas flow direction, thereby achieving effective exhaust and inflation. An air intake grille 32 is provided on the outer shell 31. The setting of the air intake grille 32 enables the air pump 33 to stably draw external air and enables the inflation chamber 43 to effectively exhaust air.

[0031] The working principle of the present technical solution is as follows: when the inflation chamber 43 is not inflated, the elastic band 41 pulls one end of the airbag 42 to move in the direction of the elastic band 41, so that the airbag 42 can be close to the inner wall of the air-conditioning suit body 1, thereby enabling the wearer to pass his hand through the sealing mechanism 4 with less effort; when it is necessary to inflate to seal the cuffs of the air-conditioning suit body 1, the operator controls the operation of the air pump 33 through the controller 36. At this time, the two-position three-way solenoid valve 34 automatically switches the valve circuit under the control of the controller 36, so that the air inlet of the air pump 33 is connected to the inflation chamber 43, and then the air pump 33 operates to suck in external air and pressurize it into the interior of the inflation chamber 43, so that the air The airbag 42 is inflated to achieve sealing at the cuff; after the airbag 42 is inflated, the pressure on the film pressure sensor 37 sandwiched between the inflation cavity 43 and the air-conditioning suit body 1 changes, and when the pressure value fed back by the film pressure sensor 37 exceeds the set threshold range, the controller 36 controls the air pump 33 to automatically stop; when the wearer needs to pull the arm out of the cuff, the controller 36 controls the valve circuit of the two-position three-way solenoid valve 34 to reset, so that the inflation cavity 43 is connected to the external environment, and at the same time the elastic band 41 releases elastic potential energy, so that the air in the inflation cavity 43 is quickly squeezed out, thereby facilitating the wearer to pull the arm out of the sealing mechanism 4.
