[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] See also Figure 1 to Figure 4 , a constant temperature and humidity machine, comprising:

[0026] A humidistat body 1, wherein two groups of vents 11 are provided on the humidistat body 1, a dehumidification unit 2 and a regeneration unit 3 are installed in the humidistat body 1, and the dehumidification unit 2 and the regeneration unit 3 are used to dehumidify the outside and dry and regenerate the dehumidification unit 2 respectively;

[0027] The regulating unit 4 is slidably connected in the humidistat body 1 and connected to the dehumidifying unit 2, and is used to switch the states of the dehumidifying unit 2 and the regeneration unit 3;

[0028] The dustproof unit 5 is slidably connected in the humidistat body 1 and is used to prevent dust from entering the vent 11;

[0029] The opening and closing unit 6 is rotatably connected in the constant humidity machine body 1 and is slidably connected to the dustproof unit 5 to fold and vibrate the dustproof unit 5.

[0030] In the embodiment of the present invention, by setting the adjustment unit 4, the position of the rotary dehumidifier 23 can be switched, thereby controlling different operation modes of the device, so that the dehumidification unit 2 and the regeneration unit 3 can be operated separately and independently. The opening and closing unit 6 is turned on, and the opening and closing unit 6 can drive the dustproof unit 5 to open or close. When the dustproof unit 5 is opened, the inside of the constant humidity machine body 1 can be inspected; when the dustproof unit 5 is closed, the dustproof unit 5 can be automatically cleaned, which has the advantages of easy maintenance and automatic cleaning of the dustproof unit 5.

[0031] In one embodiment of the present invention, Figure 2 As shown, the dehumidification unit 2 includes:

[0032] The baffle 21 is fixed inside the humidistat body 1, and the upper and lower ends are respectively connected to the inner wall of the humidistat body 1;

[0033] The support plate 22 is connected to the humidistat body 1 and is perpendicular to the baffle 21. The support plate 22 is provided with two groups of through holes 221.

[0034] The rotary dehumidifier 23 is slidably connected to the surface of the support plate 22 and communicated with the through hole 221;

[0035] The first fan 24 is installed in the constant humidity machine body 1.

[0036] In this embodiment, when dehumidification is required, the first fan 24 and the regulating unit 4 are turned on, and the regulating unit 4 can be connected to the rotary dehumidification element 23 to make the rotary dehumidification element 23 slide to the right ( Figure 2Because the baffle 21 separates the humidistat body 1 into two independent parts, the first fan 24 is turned on, so that the first fan 24 can bring the outside air into the humidistat body 1 through the vent 11. The air entering the humidistat body 1 can pass through the rotary dehumidifier 23 and the right through hole 221 in sequence, and finally be discharged from the vent 11 at the other end of the humidistat body 1. In this process, the humid air becomes dry air after being humidified by the rotary dehumidifier 23, thereby achieving the effect of drying the air.

[0037] A rubber ring may also be installed on the surface of the through hole 221 , and the rubber ring may improve the sealing performance between the through hole 221 and the rotary dehumidification element 23 .

[0038] In one embodiment of the present invention, Figure 2 As shown, the regeneration unit 3 comprises:

[0039] The second fan 31 is installed in the humidistat body 1;

[0040] The heating element 32 is connected to the constant humidity machine body 1 and corresponds to the position of the second fan 31 .

[0041] In this embodiment, when the rotary dehumidifier 23 needs to be dried, the second fan 31 is turned on and the first fan 24 is turned off, and the heating element 32 and the adjustment unit 4 are turned on at the same time, so that the adjustment unit 4 drives the rotary dehumidifier 23 to slide to the surface of the through hole 221 on the left. Therefore, the second fan 31 can bring the outside air into the humidistat body 1 through the vent 11, and the heating element 32 can heat the air entering the humidistat body 1. The hot air passes through the rotary dehumidifier 23 and the through hole 221 on the left in turn. The rotary dehumidifier 23 can be turned back to a dry state under the action of the hot air, so that the rotary dehumidifier 23 has the ability to absorb moisture again, and finally the regenerated air is discharged through the vent 11 at the other end of the humidistat body 1.

[0042] Furthermore, a humidity sensor may be installed on the side of the first fan 24, and a temperature sensor may be installed on the side of the second fan 31, so that the humidity and temperature in the dehumidification process and the regeneration process can be detected respectively.

[0043] In one embodiment of the present invention, Figure 2 As shown, the adjustment unit 4 includes:

[0044] The guide frame 41 is fixed on the support plate 22 and has a sliding member 42 slidably connected on its surface;

[0045] A lifting rod 43 is slidably connected in the sliding member 42, and an end of the lifting rod 43 is connected to the rotary dehumidification member 23;

[0046] The rotating shaft 44 is rotatably connected to the supporting plate 22, and a rotating frame 45 is mounted on the surface thereof, and the end of the rotating frame 45 is hinged to the end of the lifting rod 43;

[0047] A gear 46 mounted on the surface of the rotating shaft 44;

[0048] A fixing frame 47 is connected to the side of the supporting plate 22 and has an adjusting rod 48 slidably connected therein;

[0049] The rack 481 is provided on the side of the adjusting rod 48 and is meshedly connected with the gear 46 .

[0050] In this embodiment, when the position of the rotary dehumidifier 23 needs to be adjusted, the adjusting rod 48 is pulled or pushed to make the adjusting rod 48 slide in the fixing frame 47. The adjusting rod 48 can drive the rack 481 on its side to slide synchronously. The rack 481 can drive the rotating shaft 44 to rotate on the support plate 22 through the connection with the gear 46.

[0051] like Figure 2 As shown, when the rotating shaft 44 rotates clockwise on the support plate 22, the rotating shaft 44 can drive the rotating frame 45 to rotate clockwise synchronously, so that the rotating frame 45 can drive the lifting rod 43 to rise in the sliding member 42. Since the rotating frame 45 rotates clockwise, the lifting rod 43 can also drive the sliding member 42 to slide to the right on the surface of the guide frame 41 during the process of the lifting rod 43 rising in the sliding member 42. Therefore, in this process, the lifting rod 43 not only drives the rotary dehumidifier 23 to slide upward, but also drives the rotary dehumidifier 23 to slide to the right.

[0052] When the rotating frame 45 rotates clockwise, the end of the rotating frame 45 rotates to the highest point, and then the rotating frame 45 continues to rotate clockwise. In the following process, the lifting rod 43 will continue to drive the sliding member 42 to slide rightward on the surface of the guide frame 41, but the lifting rod 43 will slide downward in the sliding member 42 under the action of the rotating frame 45. Therefore, in this process, the lifting rod 43 will drive the rotary dehumidifier 23 to move in two directions rightward and downward until the rotary dehumidifier 23 slides to the surface of the right through hole 221. When the rotary dehumidifier 23 slides to the surface of the right through hole 221, the dehumidifier unit 2 can work.

[0053] When the rotating shaft 44 rotates counterclockwise on the supporting plate 22, in contrast to the above working process, the lifting rod 43 drives the rotary dehumidifier 23 to slide to the left, and at the same time, the lifting rod 43 drives the rotary dehumidifier 23 to slide upward first, rise to the highest point, and then slide downward until the rotary dehumidifier 23 slides to the surface of the left through hole 221 (such as Figure 2 status).

[0054] When the rotary dehumidifier 23 slides to the surface of the left through hole 221, the regeneration unit 3 can work. By setting the adjustment unit 4, the position of the rotary dehumidifier 23 can be switched, thereby controlling different operation modes of the device, so that the dehumidifier unit 2 and the regeneration unit 3 can be operated separately and independently.

[0055] Furthermore, the lower end of the lifting rod 43 can be rotatably connected to a rotating shaft, the center of the rotary dehumidifier 23 is installed on the surface of the rotating shaft, and a fan blade is installed at one end of the rotating shaft close to the second fan 31. Therefore, when the first fan 24 or the second fan 31 is running, the fan blade can drive the rotating shaft to rotate on the lifting rod 43 under the action of the wind force of the first fan 24 or the second fan 31, so that the rotating shaft can drive the rotary dehumidifier 23 to rotate on the side of the through hole 221, so that the dehumidification effect or drying effect of the rotary dehumidifier 23 is more uniform.

[0056] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the dustproof unit 5 includes:

[0057] The fixed plate 51 is fixed in the humidistat body 1;

[0058] A bracket 511 is connected between the side of the fixing plate 51 and the inner wall of the constant humidity machine body 1, and at least three groups of arc frames 52 are fixed on the bracket 511;

[0059] An arc groove 53 is provided on the fixed plate 51, and a slider 531 is slidably connected inside the arc groove 53;

[0060] The slide bars 54 are fixed on the slider 531, and the two sets of slide bars 54 are connected by an elastic member 56;

[0061] One end of the flexible filter net 55 is connected to the bracket 511 , and the other end is connected to the slide bar 54 , and the flexible filter net 55 is slidably connected to the surface of the arc frame 52 .

[0062] In this embodiment, if Figure 3 As shown, two groups of dustproof units 5 are installed, so the two groups of flexible filter nets 55 can respectively perform dustproof treatment on the two groups of ventilation ports 11, thereby improving the dustproof performance of the constant humidity machine body 1.

[0063] When the dehumidification unit 2 or the regeneration unit 3 needs to be inspected and maintained, the opening and closing unit 6 is opened, and the opening and closing unit 6 can respectively drive the two groups of sliders 531 to slide in the corresponding arc grooves 53, and the sliders 531 can drive the corresponding slide bars 54 to slide synchronously when sliding, and then the slide bars 54 can drive the flexible filter net 55 to slide on the surfaces of the three groups of arc frames 52. Since the flexible filter net 55 is elastic, the flexible filter net 55 can be folded, and then the interior of the constant humidity machine body 1 can be inspected through the two groups of ventilation holes 11, which has the advantage of easy maintenance.

[0064] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the opening and closing unit 6 includes:

[0065] The driving shaft 61 is eccentrically connected to the fixed plate 51, and a rotating gear 611 is installed on the surface. The driving shaft 61 and the rotating gear 611 are respectively installed in two groups, and the two groups of rotating gears 611 are meshed and connected;

[0066] The driving member 62 is installed on the constant humidity machine body 1, and the end of the driving shaft 61 is connected to the output end of the driving member 62; the rotating frame 63 is installed on the surface of the driving shaft 61 and is slidably connected to the surface of the slider 531.

[0067] In this embodiment, the driving member 62 is turned on, and the output end of the driving member 62 can drive the driving shaft 61 to rotate clockwise ( Figure 3 The left driving shaft 61 in the middle rotates clockwise (clockwise), and under the action of the two sets of rotating gears 611, the two sets of driving shafts 61 can rotate clockwise and counterclockwise on the fixed plate 51 respectively. The driving member 62 can be an electric motor or a pneumatic motor to drive the driving shaft 61 to rotate stably on the fixed plate 51, and is not limited to this.

[0068] The driving shaft 61 can drive the rotating frame 63 to rotate synchronously during the rotation process. When the rotating frame 63 rotates to contact the slider 531, the two groups of sliders 531 can slide in the two groups of arc grooves 53 respectively under the push of the corresponding rotating frame 63, specifically, the left slider 531 slides clockwise, and the right slider 531 slides counterclockwise, so the two groups of sliders 531 can drive the two groups of slide rods 54 to slide synchronously. At the same time, the two groups of slide rods 54 can stretch the elastic member 56, so the two groups of slide rods 54 can respectively drive the flexible filter net 55 to slide on the surface of the arc frame 52, so that the flexible filter net 55 can be retracted and folded, and then the interior of the constant humidity machine body 1 can be inspected through the two groups of ventilation holes 11.

[0069] Since the two sets of driving shafts 61 are eccentrically mounted on the fixed plate 51, when the two sets of driving shafts 61 continue to rotate, the end of the rotating frame 63 will be separated from the slider 531. When the end of the rotating frame 63 is separated from the slider 531, the two sets of sliding rods 54 can drive the two sets of sliders 531 to slide in the corresponding arc grooves 53 in opposite directions under the elastic force of the elastic member 56 until the two sets of sliders 531 slide to the end of the arc groove 53 (such as Figure 3 ), so that the two sets of slide bars 54 can spread out the two sets of flexible filter nets 55, so that the two sets of flexible filter nets 55 can respectively perform dust prevention treatment on the two sets of vents 11. And when the two sets of slide blocks 531 slide to the ends of the arc groove 53, the slide blocks 531 will vibrate under the collision of the arc groove 53, and then the flexible filter net 55 can be vibrated, so that the dust adsorbed on the surface of the flexible filter net 55 can be shaken off, realizing the automatic cleaning of the flexible filter net 55, and thus improving the use effect of the constant humidity machine body 1.

[0070] like Figure 3 and Figure 4 As shown, the two groups of rotating frames 63 are installed at staggered heights on the surfaces of the two groups of driving shafts 61, thereby preventing the two groups of rotating frames 63 from interfering with each other during rotation. The elastic member 56 can be a spring or elastic rubber. Furthermore, a groove can be provided on the surface of the arc frame 52, and the elastic member 56 is slidably connected in the groove, thereby guiding and limiting the elastic member 56, thereby improving the stability of the elastic member 56 during stretching and contraction.

[0071] The working principle of the present invention is: when dehumidification is required, the first fan 24 is turned on, and the first fan 24 can bring the outside air into the interior of the humidistat body 1 through the vent 11. The air entering the interior of the humidistat body 1 can pass through the rotary dehumidifier 23 and the through hole 221 on the right side in sequence. The humid air becomes dry air after the rotary dehumidifier 23 absorbs moisture, thereby achieving the effect of drying the air. When the rotary dehumidifier 23 needs to be dried, the second fan 31 is turned on and the first fan 24 is turned off, and the heating element 32 and the adjustment unit 4 are turned on at the same time, so that the adjustment unit 4 drives the rotary dehumidifier 23 to slide to the surface of the through hole 221 on the left side. The second fan 31 can bring the outside air into the humidistat body 1 through the vent 11, and the rotary dehumidifier 23 can return to a dry state under the action of hot air, so that the rotary dehumidifier 23 has the ability to absorb moisture again.

[0072] Turn on the driving member 62, and the output end of the driving member 62 can drive the driving shaft 61 to rotate clockwise on the fixed disk 51. The driving shaft 61 can drive the rotating frame 63 to rotate synchronously during the rotation. When the rotating frame 63 rotates to contact the slider 531, the two groups of sliders 531 can slide in the two groups of arc grooves 53 respectively under the push of the corresponding rotating frame 63, so that the two groups of sliding rods 54 can respectively drive the flexible filter net 55 to slide on the surface of the arc frame 52, so that the flexible filter net 55 can be folded, and then the interior of the constant humidity machine body 1 can be inspected through the vent 11.

[0073] When the end of the rotating frame 63 is separated from the slider 531, the two groups of slide rods 54 can drive the two groups of slide blocks 531 to slide in the corresponding arc groove 53 in the opposite direction under the elastic force of the elastic member 56, and when the two groups of slide blocks 531 slide to the end of the arc groove 53, the slider 531 will vibrate under the collision of the arc groove 53, and then the flexible filter net 55 can be vibrated, so that the dust adsorbed on the surface of the flexible filter net 55 can be shaken off, thereby realizing automatic cleaning of the flexible filter net 55 and improving the use effect of the constant humidity machine body 1.

[0074] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
