[0002] A cleanroom, also known as a dust-free workshop, clean room, or clean space, refers to an environment with a low level of contamination. Temperature and humidity control within a cleanroom is crucial for ensuring product quality, protecting precision equipment, and improving personnel comfort. Therefore, during the design and operation of a cleanroom, temperature and humidity parameters should be strictly controlled to ensure they fluctuate within a suitable range.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] See Figure 1-2 and Figure 9As shown, an automatic control device for cleanroom air conditioning includes a fixed base 1 and a housing 2 disposed on the fixed base 1. The housing 2 is detachably mounted on the fixed base 1 by four sets of locking mechanisms 3. After the two are connected, a chamber 4 is formed between the fixed base 1 and the housing 2, and the opening of the chamber 4 is opposite to the fixed base 1. A controller 5 and a temperature and humidity sensor 6 are disposed in the chamber 4. An operation panel 7 is disposed at the opening of the chamber 4. The temperature and humidity sensor 6 and the operation panel 7 are respectively connected to the controller 5. It should be noted that the number of sets of locking mechanisms 3 is only one embodiment and is not intended to limit the scope of this application. In actual settings, other numbers of sets can be used, such as two sets, six sets, etc., depending on actual needs. The operation panel 7 is a touch screen panel.

[0032] Further, see Figure 3 and Figure 6-7 As shown, in this embodiment, the mounting base 1 has a wire-passing hole 11. In use, external wires are passed through the wire-passing hole 11 into the chamber 4 and connected to the controller 5. In this embodiment, in order to arrange the wires more aesthetically at the wire-passing hole 11, the mounting base 1 has a wire-avoiding groove 12. The wires pass through the wire-avoiding groove 12 and then pass into the wire-passing hole 11. The outer shell 2 has a clearance groove 21. By setting the clearance groove 21, interference between the outer shell 2 and the wires is avoided when the outer shell 2 is connected to the mounting base 1.

[0033] Further, see Figure 3-5 As shown, in this embodiment, the locking mechanism 3 includes a locking rod 31 with its front end passing through the fixed seat 1 and sliding within the fixed seat 1, a mounting seat 32 fixed on the fixed seat 1, and a spring 33 fitted on the locking rod 31. A ring of protruding ribs 34 is provided circumferentially in the middle of the outer surface of the locking rod 31. The protruding ribs 34 are integrally formed with the locking rod 31. When the protruding ribs 34 abut against the fixed seat 1, the locking rod 31 slides outward through the mounting seat 32 to the maximum distance. At this time, the front end of the locking rod 31 extends out of the mounting seat 32. In this embodiment, the part of the locking rod 31 extending out of the mounting seat 32 is hemispherical.

[0034] See also Figure 3-5As shown, in this embodiment, the mounting base 32 and the fixing base 1 are integrally formed. The mounting base 32 has a mounting slot 321. In this embodiment, the mounting slot 321 includes a mounting hole 3211 and a connecting groove 3212. The mounting hole 3211 communicates with the upper end face of the mounting base 32 through the connecting groove 3212. Both the mounting hole 3211 and the connecting groove 3212 penetrate the front and rear end faces of the mounting base 32. The width of the connecting groove 3212 is smaller than the diameter of the mounting hole 3211. The rear end of the locking rod 31 is pressed into the mounting hole 3211 from the connecting groove 3212. In this embodiment, the diameter of the mounting hole 3211 is slightly larger than the rear end of the locking rod 31. Therefore, the rear end of the locking rod 31 can slide in the mounting hole 3211.

[0035] See also Figure 3-5 As shown, the spring 33 is sleeved on the locking rod 31 between the protrusion 34 and the mounting base 32. Without the action of external force, the spring 33 has a tendency to drive the locking rod 31 to move outward toward the fixed base 1. In this embodiment, the two ends of the spring 33 are respectively connected to the fixed base 1 and the mounting base 32 in an abutting manner, but it is not limited to the abutting manner. For example, welding can also be used.

[0036] Further, see Figure 6 As shown, in this embodiment, the outer shell 2 has a locking groove 22 through which the front end of the locking rod 31 can pass. The locking groove 22 corresponds one-to-one with the locking mechanism 3. Each locking groove 22 is a hemispherical groove, and the dimensions of the hemispherical groove are the same as the hemispherical dimensions of the front end of the locking rod 31. During locking, see... Figure 5 As shown, the outer shell 2 drives the locking rod 31 to move into the fixed base 1 by compression. After the outer shell 2 is installed in place, the locking rod 31 moves outward from the fixed base 1 under the reaction force of the spring 33, so that the hemisphere at the front end of the locking rod 31 sinks into the locking groove 22, thereby locking the outer shell 2 onto the fixed base 1. When it is necessary to disassemble the outer shell 2, simply pull the outer shell 2 outward. However, it should be noted that the pulling force should not be too large or too strong to prevent the connecting line between the operation panel 7 and the controller 5 from being torn.

[0037] Further, see Figure 6 As shown, in this embodiment, a ventilation opening 23 is provided on the side wall of the outer shell 2. By setting the ventilation opening 23, the airflow in the clean room can flow through the outer shell 2 and through the chamber 4, thereby achieving more accurate monitoring of the temperature and humidity in the clean room.

[0038] Further, see Figure 3 As shown, in this embodiment, to facilitate the installation of the device of this application, the fixing base 1 is provided with fixing holes 13. During installation, the locking screws fix the fixing base 1 through the fixing holes 13. Of course, the above is only one embodiment and is not intended to limit the scope of this application. For specific implementation details, please refer to [reference needed]. Figure 8 As shown, a fixing adhesive 8 can also be provided on the fixing base 1 for fixing by adhesive.

[0039] The working principle of this utility model is as follows:

[0040] In use, first connect the air conditioner to the controller 5 via the corresponding line and power it on; then set the temperature and humidity through the operation panel 7 and start the air conditioner; at this time, the temperature and humidity sensor 6 will feed back the monitored parameters to the controller 5. The controller 5 will compare the temperature and humidity signal fed back by the temperature and humidity sensor 6 with the temperature and humidity set on the operation panel 7 and control the operation of the air conditioner to adjust the clean room and keep the temperature and humidity of the clean room within the set range.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
